通过吸嘴接口相对第一壳体侧的定位，可以以简单的方式从站立位置起实现抽吸功能，其中，根据应用目的和用户预设可以调整管装置上的长度。By positioning the suction nozzle connection with respect to the first housing side, the suction function can be realized in a simple manner from a standing position, wherein the length on the tube arrangement can be adjusted according to the purpose of application and user specification.

由此，吸尘器例如可以用作地面吸尘器，在其中，吸尘器经由地面吸嘴被放置在待清洁的面上，并且吸尘器能够用作手持式抽吸器，其是可手持的。Thus, the vacuum cleaner can be used, for example, as a floor vacuum cleaner, in which the vacuum cleaner is placed on the surface to be cleaned via the floor nozzle, and can be used as a hand-held vacuum cleaner, which is hand-held.

根据本发明的吸尘器可以有效地用于在家具或类似物下方进行抽吸。通过吸嘴接口与壳体之间的间距的可延长性，使得壳体可以停留在家具下方的空间以外，并且只需要将抽吸吸嘴连同管装置的相应的管区域探入到该空间中。The vacuum cleaner according to the invention can be effectively used for suctioning under furniture or the like. Due to the extendable distance between the nozzle connection and the housing, the housing can remain out of the space under the furniture and only the suction nozzle with the corresponding tube area of the tube arrangement has to be inserted into this space .

尤其地，在抽吸吸嘴固定在吸嘴接口上的情况下，抽吸吸嘴与第一壳体侧的间距能够以能锁定的方式调整。由此得到可变的使用可能性。站立位置可以得到固定。In particular, the distance between the suction nozzle and the first housing side can be adjusted in a lockable manner when the suction nozzle is fastened to the nozzle connection. This results in variable possibilities of use. The standing position can be fixed.

Furthermore, long flow paths can thus be achieved without significant power limitations, whereby an effective reduction of noise emissions can be achieved.

在一种实施例中，管装置具有至少一个刚性的管，并且尤其是被构造为具有至少两个刚性的管的伸缩装置。由此可以以简单的方式实现管装置的长度可调整性并且尤其能够实现吸嘴接口相对壳体的第一壳体侧的间距的可调整性。In one embodiment, the tube arrangement has at least one rigid tube and is designed in particular as a telescoping device with at least two rigid tubes. In this way, a length adjustability of the tube arrangement and in particular an adjustability of the distance of the suction nozzle connection relative to the first housing side of the housing can be realized in a simple manner.

十分特别有利的是，连接管被构造为用于握住吸尘器的弓形把手。由此，连接管也用作握持元件。于是不必设置附加的弓形把手，并且可以使吸尘器的质量保持得小。通过将连接管布置在壳体上方也得到例如用于抽吸地面或在用作手持式抽吸器时的最佳的握持功能。It is very particularly advantageous if the connecting pipe is configured as a bow-shaped handle for holding the vacuum cleaner. The connecting tube thus also serves as a grip element. It is then not necessary to provide an additional bow handle, and the mass of the vacuum cleaner can be kept low. The arrangement of the connecting pipe above the housing also results in an optimal handling function, for example for vacuuming floors or when used as a hand-held suction device.

此外有利的是，分离器装置与距第一壳体侧相比更靠近第二壳体侧地定位，并且尤其是布置在第二壳体侧上。由此得到壳体和进而吸尘器的紧凑的结构。It is also advantageous if the separator device is positioned closer to the second housing side than to the first housing side, and in particular is arranged on the second housing side. This results in a compact construction of the housing and thus of the vacuum cleaner.

出于相同的原因而有利的是，抽吸机组与距第二壳体侧相比更靠近第一壳体侧地定位，并且尤其地，分离器装置和抽吸机组沿第一延伸轴线上下相叠地定位。因此得到紧凑的结构。For the same reason it is advantageous if the suction unit is positioned closer to the first housing side than to the second housing side and in particular the separator device and the suction unit are positioned one above the other along the first axis of extension.

This results in long flow paths without a significant reduction in efficiency or suction power, which promote effective noise reduction.

出于相同的原因而有利的是，流动路径包括第三区域，第三区域布置在壳体中并具有沿着第一延伸轴线的、与第二区域中的主流动方向相反的主流动方向。For the same reason it is advantageous if the flow path comprises a third region which is arranged in the housing and has a main flow direction along the first extension axis opposite to the main flow direction in the second region.

在此有利的是，用于在第一区域和第二区域之间的流动的转向区域通过管装置与壳体并且尤其是第二壳体侧之间的连接管形成。由此得到紧凑的结构。连接管可以例如也用作弓形把手。It is advantageous here if the deflection region for the flow between the first region and the second region is formed by the connecting pipe between the pipe arrangement and the housing, in particular the second housing side. This results in a compact structure. The connection tube can, for example, also be used as a bow handle.

此外有利的是，用于在壳体中的第二区域与第三区域之间的流动的转向区域尤其是在抽吸机组与第一壳体侧之间形成。由此得到具有最佳的空间利用的紧凑的结构。在一种实施方式中，在转向区域中布置有多孔的材料例如泡沫材料以用于降噪。It is also advantageous if a diversion region for the flow between the second region and the third region in the housing is formed, in particular between the suction unit and the first housing side. This results in a compact construction with optimum space utilization. In one embodiment, a porous material, for example a foam material, is arranged in the deflection region for noise reduction.

此外有利的是，壳体中的第三区域形成在壳体器壁与分离器装置和抽吸机组之间，其中，分离器装置和抽吸机组尤其是参照第一延伸轴线上下相叠地布置。由此，抽吸机组的已清洁的排气可以经由相对较大的区域排出到周围环境中。It is also advantageous if a third region in the housing is formed between the housing wall and the separator device and the suction unit, wherein the separator device and the suction unit are arranged one above the other, in particular with reference to the first axis of extension. . As a result, the cleaned exhaust gas of the suction unit can be discharged into the surroundings over a relatively large area.

有利地，在壳体器壁上布置有至少一个逸出开口，逸出开口与第三区域流体作用地(fluidwirksam)连接。由此可以高效地排出已清洁的排气。排出可以以降低噪音的方式执行。Advantageously, at least one outlet opening is arranged on the housing wall, which outlet opening is fluidically connected to the third region. Cleaned exhaust gas can thus be discharged efficiently. Evacuation can be performed in a noise-reducing manner.

有利的是，在壳体上，在固定有管装置的第三壳体侧上布置有用于抽吸机组的排气的至少一个逸出开口，其中，第三壳体侧尤其是布置在第一壳体侧与第二壳体侧之间。由此在壳体的紧凑的结构的情况下得到最佳的流动引导。Advantageously, at least one escape opening for the exhaust air of the suction unit is arranged on the housing on the third housing side to which the pipe arrangement is fastened, wherein the third housing side is arranged in particular on the first Between the housing side and the second housing side. This results in an optimal flow guidance with a compact design of the housing.

尤其是设置了多个逸出开口，其中，逸出开口在沿第一延伸轴线的方向上布置在壳体上。由此，可以经由相对较大的面积排出抽吸机组的排气。可以实现噪音最小化的排气排出。In particular, a plurality of escape openings are provided, wherein the escape openings are arranged on the housing in the direction of the first extension axis. As a result, the exhaust gas of the suction unit can be discharged over a relatively large area. Exhaust discharge with minimum noise can be realized.

为了降噪而此外有利的是，在至少一个逸出开口上布置有开放式多孔的结构，例如泡沫元件，排气必须穿流动穿过泡沫元件。For noise reduction it is also advantageous if an open perforation is arranged on at least one escape opening For structures such as foam elements, the exhaust gas must flow through the foam element.

在一种实施方式中，在壳体上布置有能打开的门，经由该门可以接近壳体的内部空间中的布置有分离器装置的区域。门可以与分离器装置分隔开或者布置在其上。在门布置在分离装置上的情况下，随着将分离器装置从壳体取出而去除了门(并且在此打开)。可以以简单的方式去除收集到的脏物。In one embodiment, an openable door is arranged on the housing, via which door the region in the interior of the housing where the separator device is arranged can be accessed. The door may be separate from the separator device or arranged thereon. In case the door is arranged on the separating device, the door is removed (and opened here) as the separator device is taken out of the housing. The collected dirt can be easily removed.

在一种实施例中，分离器装置构造为过滤器-分离器装置，过滤器-分离器装置尤其是包括(用于粗尘的)预分离器和用于灰尘(细尘)的过滤器装置，其中，用于灰尘的过滤器装置尤其是构造为筒匣式滤芯。由此得到对附着有脏物的抽吸流的有效的清洁(过滤)。通过预分离器，根据预分离器的构造例如收集大于200μm的、大于150μm的或大于100μm的灰尘颗粒。用于(细)灰尘的过滤器装置于是收集更细小的灰尘颗粒。可以实现吸尘器和尤其是壳体的紧凑的结构。可以以简单的方式执行脏物排空。此外可以以简单的方式执行过滤器更换。In one embodiment, the separator device is designed as a filter-separator device, which in particular comprises a pre-separator (for coarse dust) and a filter device for dust (fine dust) , wherein the filter device for dust is in particular designed as a cartridge filter element. This results in an effective cleaning (filtering) of the suction flow on which dirt is attached. Depending on the configuration of the pre-separator, for example, dust particles larger than 200 μm, larger than 150 μm or larger than 100 μm are collected by the pre-separator. The filter arrangement for (fine) dust then collects finer dust particles. A compact construction of the vacuum cleaner and especially the housing can be achieved. Dirt emptying can be carried out in a simple manner. Furthermore, filter replacement can be carried out in a simple manner.

在一种实施例中，抽吸机组包括风扇马达，给风扇马达配属尤其是形式为罩的流动转向元件，其中，在风扇马达上提供具有相反的主流动方向的至少一个第一流动区域和第二流动区域。通过壳体中的这样的“子流动区域”可以实现有效的降噪，也就是说可以基于壳体中的噪音反射实现噪音排放的减小。In one embodiment, the suction unit comprises a fan motor to which a flow deflection element, in particular in the form of a hood, is assigned, wherein at least one first flow region and a second flow region with opposite main flow directions are provided on the fan motor. 2. Flow area. Effective noise reduction can be achieved by means of such “subflow regions” in the housing, that is to say a reduction in noise emissions can be achieved due to noise reflections in the housing.

此外有利的是，设置有排气过滤器，其关于流动后置于风扇马达，或者布置在风扇马达与流动转向元件之间。通过这样的排气过滤器例如可以过滤出风扇马达的磨损粒(Abrieb)。It is also advantageous if an exhaust filter is provided which is downstream of the fan motor with respect to the flow or is arranged between the fan motor and the flow deflection element. For example, wear particles of the fan motor can be filtered out by means of such an exhaust air filter.

有利的是，在第一流动区域与第二流动区域之间的过渡部上布置有由具有噪音反射率为至少94％的抗噪(schallhart)的材料构成的尤其是呈环形的元件。由此得到噪音排放的减小。在过渡部上例如也布置有泡沫塑料元件。It is advantageous if an in particular ring-shaped element is arranged at the transition between the first flow area and the second flow area and is made of a noise-resistant material with a noise reflectance of at least 94%. This results in a reduction in noise emissions. For example, a foam element is also arranged on the transition.

此外有利的是，在风扇马达上沿流动路径布置有多孔的材料并且尤其是泡沫材料，用以反射噪音。由此得到噪音排放的减小。It is also advantageous if a porous material, in particular a foam material, is arranged along the flow path on the fan motor in order to reflect noise. This results in a reduction in noise emissions.

根据本发明的吸尘器不仅可以在地面吸嘴固定在吸嘴接口上并且吸尘器以地面吸嘴放置在待清洁的面上时用作地面抽吸器，而且也可以用作手持式抽吸器，那么其中，吸尘器尤其是经由弓形把手被自由握持。由此得到广泛的使用可能性。The vacuum cleaner according to the invention can be used not only as a floor suction device, but also as a hand-held suction device when the floor suction nozzle is fastened to the nozzle connection and the vacuum cleaner is placed on the surface to be cleaned with the floor suction nozzle. In this case, the vacuum cleaner is held freely, in particular via the bow handle. This results in a wide range of possibilities of use.

在一种实施例中，长度能调整的管装置包括至少一个第一管、第二管、第三管，其中，第一管以能纵向移动的方式在第二管中引导，并且第二管以能纵向移动的方式在第三管中引导，并且包括第一锁定装置(其在第一管与第二管之间起作用，其中，在第一锁定装置的能松开的锁定位置中，第一管就纵向可移动性而言紧固在第二管上)、第二锁定装置(其在第二管与第三管之间起作用，其中，在第二锁定装置的能松开的锁定位置中，第二管就纵向可移动性而言紧固在第三管上)、第三锁定装置(其作用到第一管、第二管和第三管上，其中，第三锁定装置具有能松开的锁定位置和解锁位置，在锁定位置中，第二管就纵向可移动性而言紧固在第三管上，在解锁位置中，释放了第二管相对第三管的纵向移动)，其中，第三锁定装置就从锁定位置过渡到解锁位置中而言通过第一管相对于第二管的定位并且/或者通过力进行控制，利用该力，第三锁定装置作用到第二管上。In one embodiment, the length-adjustable tube arrangement comprises at least one first tube, a second tube, a third tube, wherein the first tube is guided longitudinally displaceably in the second tube, and the second tube Guided in a third tube in a longitudinally movable manner and comprising first locking means (which act between the first tube and the second tube, wherein, in the releasable locking position of the first locking means, The first tube is fastened on the second tube in terms of longitudinal mobility), the second locking device (which acts between the second tube and the third tube, wherein the releasable In the locked position, the second tube is fastened on the third tube in terms of longitudinal mobility), the third locking device (which acts on the first tube, the second tube and the third tube, wherein the third locking device Has a releasable locking position, in which the second tube is fastened to the third tube in terms of longitudinal displaceability, and an unlocking position, in which the longitudinal direction of the second tube relative to the third tube is released movement), wherein the third locking device is controlled by the positioning of the first tube relative to the second tube and/or by the force with which the third locking device acts on the first tube in terms of transition from the locked position to the unlocked position On the second pipe.

长度能调整的管装置级联式地构建。第一管能相对于第二管移动，其中，第一锁定装置在其锁定位置中将第一管紧固在第二管上。The length-adjustable tube arrangement is constructed in cascade. The first tube is movable relative to the second tube, wherein the first locking device secures the first tube on the second tube in its locked position.

第二管能在第三管中移动。但只有当第三锁定装置释放可移动性时才能够实现该可移动性。因为从第三锁定装置的锁定位置到解锁位置的过渡通过第一管的定位或通过力来控制，也就是说受定位控制或受力控制，所以当实现第一管相对于第二管的特定的定位时，该过渡在一定程度上自动得到。不需要单独的操纵元件。The second tube is movable within the third tube. However, this mobility is only possible when the third locking device releases the mobility. Since the transition from the locked position of the third locking device to the unlocked position is controlled by the positioning of the first tube or by force, that is to say by position control or force control, when a specific position of the first tube relative to the second tube is achieved The transition is somewhat automatic when positioned. No separate operating elements are required.

于是，当第三锁定装置位于解锁位置中时，可以经由第二锁定装置调整第二管相对于第三管的相对定位。Then, the relative positioning of the second tube relative to the third tube can be adjusted via the second locking device when the third locking device is in the unlocked position.

在简单的可操作性的情况下得到用于管装置的较大的长度调整范围。A large length adjustment range for the tube arrangement results with simple operability.

长度能调整的管装置在此具有高的操作舒适性。The length-adjustable tube arrangement provides high operating comfort.

有利的是，第一锁定装置和第三锁定装置如下这样地相互联接，即，在第三锁定装置的解锁位置中，使第一锁定装置位于其锁定位置中。由此总是仅能够同时出现一个管相对于其他的管的运动。如果第一管相对第二管运动，那么第二管不能够相对第三管运动。如果第二管相对第三管运动，那么第一管不能够相对第二管运动。由此得到简单的可调整性和高的操作舒适性。It is advantageous if the first locking device and the third locking device are coupled to one another in such a way that, in the unlocked position of the third locking device, the first locking device is in its locking position. As a result, only a movement of one tube relative to the other can always take place at the same time. If the first tube moves relative to the second tube, the second tube cannot move relative to the third tube. If the second tube moves relative to the third tube, the first tube cannot move relative to the second tube. This results in simple adjustability and high operating comfort.

此外有利的是，第一锁定装置和第二锁定装置如下这样地相互联接，即，在第三锁定装置的锁定位置中，使第一锁定装置和第二锁定装置能够共同地从其各自的锁定位置被带到解锁位置中，或者共同地位于其各自的解锁位置中。由此能够利用共同的操纵元件作用到第一锁定装置上和第二锁定装置上。尤其是可以经由第二锁定装置的相应的阻止元件居间地作用到第一锁定装置上，而不用在此取消第二管相对第三管的(通过第三锁定装置进行的)锁定。即使当第二锁定装置位于解锁位置中，经由在其锁定位置中的第三锁定装置也使第二管紧固在第三管上。Furthermore, it is advantageous if the first locking device and the second locking device are coupled to each other in such a way that, in the locked position of the third locking device, the first locking device and the second locking device can be jointly released from their respective locking The positions are brought into the unlocked position, or are collectively located in their respective unlocked positions. It is thus possible to act on the first locking device and on the second locking device with a common actuating element. In particular, the first locking device can be acted on via a corresponding blocking element of the second locking device, without canceling the locking of the second tube relative to the third tube (by means of the third locking device). Even when the second locking device is in the unlocked position, the second tube is fastened to the third tube via the third locking device in its locked position.

此外有利的是，在第三锁定装置的解锁位置中，第一锁定装置和第二锁定装置脱联，其中，第二锁定装置能被带到锁定位置中，并且第二管相对第三管的定位通过第二锁定装置能够以能锁定的方式调整。由此得到针对长度可调整性的很大的长度范围。在第三锁定装置的解锁位置中不必再作用到第一锁定装置上，这是因为该第一锁定装置位于锁定位置中。在简单的可操作性的情况下得到紧凑的结构。Furthermore, it is advantageous if, in the unlocked position of the third locking device, the first locking device and the second locking device are disengaged, wherein the second locking device can be brought into the locked position and the second tube is locked relative to the third tube. The positioning can be adjusted in a lockable manner by means of the second locking device. This results in a large length range for length adjustability. In the unlocked position of the third locking device, it is no longer necessary to act on the first locking device, since the first locking device is in the locked position. A compact structure is obtained with simple maneuverability.

在一种实施例中，第一锁定装置具有第一探入元件，第一探入元件尤其是球体或滚子，其在锁定位置中探入到第一管的第一凹部中，并且其为了解锁而能够从第一凹部中移出。尤其是在锁定位置中，探入元件也探入到第二管的相应的凹部中。由此实现第一管与第二管之间的形状锁合，并且第一管就其长度可移动性而言紧固在第二管上。当相应的第一探入元件至少从第一凹部移出时，取消了形状锁合并且能够实现第一管与第二管之间的相对的可移动性。In one embodiment, the first locking device has a first protruding element, in particular a ball or a roller, which protrudes into a first recess of the first tube in the locked position and which provides for unlocked to be able to move out of the first recess. In particular in the locked position, the probing element also protrudes into a corresponding recess of the second tube. A form-fit between the first tube and the second tube is thereby achieved and the first tube is fastened on the second tube in terms of its length displaceability. When the respective first penetrating element is moved at least out of the first recess, the positive fit is canceled and a relative movability between the first tube and the second tube can be achieved.

第一管尤其具有多个沿第一管的纵向方向间隔开的第一凹部。由此可以分级地调整和锁定第一管相对第二管的多个不同的长度定位。In particular, the first tube has a plurality of first recesses spaced apart in the longitudinal direction of the first tube. A plurality of different length positions of the first tube relative to the second tube can thus be adjusted and locked in stages.

此外有利的是，第一锁定装置具有能运动的第一阻止元件，其在锁定位置中阻止第一探入元件从第一凹部中移出，并且在解锁位置中释放移出。能运动的第一阻止元件的定位确定了是否能够实现移出。由此得到简单的锁定可能性，其又可以以简单的方式取消。It is also advantageous if the first locking device has a first movable blocking element, which in the locked position prevents the first penetrating element from moving out of the first recess, and in the unlocked position releases it. The positioning of the first movable blocking element determines whether removal is possible. This results in a simple locking possibility, which in turn can be canceled in a simple manner.

尤其是在第一阻止元件上布置有用于第一探入元件的第一容纳部，第一探入元件在解锁位置中可以探入到该第一容纳部中。由此能够实现从第一管的第一凹部移出，以便取消第一管与第二管之间的形状锁合，并且能够实现长度可移动性。In particular, a first receptacle for the first penetration element, into which the first penetration element can penetrate in the unlocked position, is arranged on the first blocking element. This makes it possible to move out of the first recess of the first tube in order to cancel the form-fit between the first tube and the second tube and to achieve length displaceability.

有利的是，第一阻止元件能平行于管装置的纵向方向移动。由此能够实现通过用于第一移动装置和第二移动装置的唯一的操纵元件进行的移动运动。Advantageously, the first blocking element is displaceable parallel to the longitudinal direction of the tube arrangement. This makes it possible to realize a displacement movement by means of a single operating element for the first displacement device and the second displacement device.

此外有利的是，设置了复位装置和尤其是弹簧装置，其在没有外力施加到第一阻止元件上的情况下力求将该第一阻止元件带到针对第一探入元件的阻止位置中。由此得到简单的可操作性。通过复位装置的复位力，在相应定位第一凹部的情况下可以以自动方式实现锁定。It is also advantageous if a restoring device and in particular a spring device is provided which, without external force acting on the first blocking element, seeks to bring the first blocking element into the blocking position for the first penetration element. This results in simple operability. By means of the restoring force of the restoring device, locking can be effected automatically with corresponding positioning of the first recess.

出于和上面结合第一锁定装置所提到的那样相同的原因而有利的是，第二锁定装置具有第二探入元件，第二探入元件在锁定位置中探入到第二管的第二凹部中，并且第二探入元件能够从第二凹部中移出以便解锁。For the same reasons as mentioned above in connection with the first locking device, it is advantageous if the second locking device has a second protruding element, which in the locked position protrudes into the first protruding part of the second tube. and the second penetrating element can be moved out of the second recess for unlocking.

此外，出于结合上面提到的结合第一锁定装置所阐述的原因而有利的是，第二管具有多个沿第二管的纵向方向间隔开的第二凹部。Furthermore, it is advantageous for the reasons explained above in connection with the first locking device that the second tube has a plurality of second recesses spaced apart in the longitudinal direction of the second tube.

此外，出于上面提到的原因而有利的是，第二锁定装置具有能运动的第二阻止元件，其在锁定位置中阻止第二探入元件从第二凹部中移出，并且在解锁位置中释放移出。Furthermore, it is advantageous for the reasons mentioned above that the second locking device has a second movable blocking element, which in the locked position prevents the second probing element from moving out of the second recess, and in the unlocked position Release to move out.

此外，出于和上面所提到的那样相同的原因而有利的是，在第二阻止元件上布置有用于第二探入元件的第二容纳部，第二探入元件在解锁位置中可以探入到该第二容纳部中。Furthermore, for the same reasons as mentioned above, it is advantageous if a second receptacle for a second penetrating element is arranged on the second blocking element, which can be poked into in the unlocked position. into the second housing.

此外出于上面提到的原因而有利的是，第二阻止元件能平行于管装置的纵向方向移动。Furthermore, it is advantageous for the reasons mentioned above if the second blocking element is displaceable parallel to the longitudinal direction of the tube arrangement.

此外出于上面提到的原因而有利的是，为第二锁定装置设置复位装置和尤其是弹簧装置，其在没有外力施加到第二阻止元件上的情况下力求将该第二阻止装置带到针对第二探入元件的阻止位置中。Furthermore, for the above-mentioned reasons, it is advantageous to provide a reset device and in particular a spring device for the second locking device, which, without external force being applied to the second blocking element, strives to bring the second blocking device to In the blocking position for the second penetration element.

此外有利的是，第三锁定装置具有第三探入元件，并且第二管和第三管具有相对应的容纳部，第三探入元件在锁定位置中定位在该容纳部中，并且第二管紧固在第三管上。由此可以以简单的方式通过借助第三探入元件的形状锁合实现第二管在第三管上的紧固。It is also advantageous if the third locking device has a third penetration element and the second tube and the third tube have corresponding receptacles in which the third penetration element is positioned in the locked position and the second The tube is fastened to the third tube. The fastening of the second tube to the third tube can thus be achieved in a simple manner by form-fitting by means of the third penetrating element.

十分特别有利的是，第一管具有配属于第三锁定装置的凹部，第三探入元件在第三锁定装置的解锁位置中探入到该凹部中，并且在此，至少从第三管的容纳部中移出。由此可以以简单的方式经由第一管相对第二管的定位进行控制地将第三锁定装置从锁定位置带到解锁位置中，以便能够实现第二管与第三管之间的可运动性。It is very particularly advantageous if the first tube has a recess assigned to the third locking device, into which the third protruding element penetrates in the unlocked position of the third locking device, and in this case at least from the third tube out of the container. As a result, the third locking device can be brought in a controlled manner from the locking position into the unlocking position via the positioning of the first tube relative to the second tube in a simple manner, in order to enable movability between the second tube and the third tube. .

有利地，第二管在第三锁定装置的锁定位置上形成针对第三探入元件的阻止器壁，阻止器壁使第三探入元件保持在第二管的和第三管的容纳部中，并且因此能够实现第二管和第三管之间的形状锁合，用以阻止相应的可运动性。Advantageously, the second tube forms a stop wall for the third penetrating element in the locked position of the third locking device, the stop wall holding the third penetrating element in the receptacle of the second tube and of the third tube , and thus enables a form-fit between the second tube and the third tube to prevent a corresponding movability.

第三锁定装置的第三探入元件或第三锁定装置的力加载元件尤其是沿管装置的纵向方向布置在第一锁定装置的第一探入元件与第二锁定装置的第二探入元件之间。由此得到具有大的长度调整范围的紧凑的结构。The third probing element of the third locking device or the force application element of the third locking device is arranged in particular in the longitudinal direction of the tube device between the first probing element of the first locking device and the second probing element of the second locking device between. This results in a compact construction with a large length adjustment range.

在一种实施方式中设置了力加载元件，其尤其是被弹簧加载，并且其在第三锁定装置的锁定位置中使第二管力锁合地(kraftschlüssig)紧固在第三管上，其中，在第三锁定装置的解锁位置中取消了力锁合的紧固。在该实施方式中，没有在第三管与第二管之间设置形状锁合紧固，而是设置力锁合紧固。力加载元件提供了用于力锁合的固定的必要的力。该固定可以通过第一管相对第二管的相应的定位来取消。该固定也可以通过用户在力加载元件上的直接干预来取消。In one embodiment, a force loading element is provided which is in particular spring-loaded and which, in the locked position of the third locking device, fastens the second tube non-positively to the third tube, wherein , the non-positive fastening is canceled in the unlocked position of the third locking device. In this embodiment, no form-fitting fastening but a force-fitting fastening is provided between the third tube and the second tube. The force-loading element provides the necessary force for a force-locked fastening. This fixation can be canceled by a corresponding positioning of the first tube relative to the second tube. This fixation can also be canceled by direct user intervention on the force-exerting element.

当设置了推动件时，得到尤其是通过唯一的操纵元件实现的简单的可操作性，推动件能关于管装置纵向移动，并且推动件与第一锁定装置的第一阻止元件和第二锁定装置的第二阻止元件联接。在第三锁定装置的锁定位置中尤其是可以通过推动件同步移动第一阻止元件和第二阻止元件。由此得到简单的可操作性。即使当第二锁定装置的阻止元件移动至解锁位置时，如果第三锁定装置在锁定位置中，那么第二管仍保持紧固在第三管上。Simple operability, in particular by means of a single actuating element, is obtained when a pusher is provided, which can be moved longitudinally with respect to the pipe arrangement and which is connected with the first blocking element of the first locking device and the second locking device The second prevents the coupling of the element. In the locking position of the third locking device, in particular the first blocking element and the second blocking element can be moved synchronously by means of the pusher. This results in simple operability. Even when the blocking element of the second locking device is moved into the unlocked position, the second tube remains fastened to the third tube if the third locking device is in the locked position.

有利地，推动件以能纵向移动的方式布置在管装置或装配有该管装置的壳体上。由此得到具有最佳的可操作性的节省空间的安装。Advantageously, the pusher is arranged in a longitudinally displaceable manner on the tube arrangement or on the housing fitted with the tube arrangement. This results in a space-saving installation with optimum operability.

在此有利的是，推动件永久地与第二阻止元件连接。由此，当第三锁定装置位于解锁位置中时，可以借助操纵推动件以简单的方式调整第二管相对第三管的相对定位。It is advantageous here if the pusher is permanently connected to the second blocking element. As a result, when the third locking device is in the unlocked position, the relative positioning of the second tube relative to the third tube can be adjusted in a simple manner by actuating the pusher.

此外有利的是，第一阻止元件并不永久地与推动件连接，并且沿移动方向的移动运动通过推动件经过推挤实现。由此可以经由推动件在第三锁定装置的锁定位置中作用到第一阻止元件上，而不必设置附加的操纵元件。It is also advantageous if the first blocking element is not permanently connected to the pusher and the displacement movement in the direction of movement is achieved by pushing the pusher through. It is thus possible to act on the first blocking element via the push element in the locked position of the third locking device without having to provide an additional actuating element.

推动件与第一阻止元件之间的联接尤其是在第三锁定装置的锁定位置中存在，并且在第三锁定装置的解锁位置中，推动件与第一阻止元件脱联并且尤其是间隔开。由此得到设计结构上简单的结构。只需要设置一个操纵元件也就是推动件，就能够实现在大的长度范围内的长度可调整性。The coupling between the pusher and the first blocking element exists in particular in the locked position of the third locking device, and in the unlocked position of the third locking device the pusher is decoupled from the first blocking element and in particular spaced apart. This results in a structurally simple structure. Length adjustability within a large length range can be realized by providing only one operating element, that is, a push piece.

在一种实施例中，用于清洁工具的第一接口和尤其是抽吸吸嘴设置在管装置上，其中，第一接口尤其是布置在第一管上。由此得到简单的长度可调整性。In one embodiment, a first connection for the cleaning tool and in particular a suction nozzle is arranged on the pipe arrangement, wherein the first connection is arranged in particular on the first pipe. This results in simple length adjustability.

此外可以设置的是，用于与抽吸机组流体作用连接的第二接口布置在管装置上，并且在此尤其是布置在第三管上。于是，抽吸流可以引导穿过管装置。Furthermore, it can be provided that the second connection for the fluidic connection to the suction unit is arranged on the pipe arrangement, and here in particular on the third pipe. A suction flow can then be guided through the tube arrangement.

有利地，在吸尘器的壳体上或在管装置上布置有能纵向移动的推动件，经由推动件可以作用到第一锁定装置和第二锁定装置上，用以建立各自的解锁位置。由此得到简单的可操作性，其中，只需要设置一个操纵元件(也就是推动件)，就能够实现针对长度可调节性的较大的长度范围。Advantageously, a longitudinally displaceable pusher is arranged on the housing of the vacuum cleaner or on the pipe arrangement, via which the first locking device and the second locking device can be acted upon in order to establish the respective unlocked position. This results in simple operability, in which only one actuating element (that is to say a pusher) has to be provided to enable a large length range for the length adjustability.

给容纳笼尤其配属有盖，在盖上安置有至少一个销形的作用元件，销形的作用元件在盖闭合时探伸到容纳空间中，并且销形的作用元件在盖相对于容纳笼运动时可以作用到容纳空间中的脏物上。In particular, a cover is assigned to the holding cage, on which at least one pin-shaped active element is arranged, which protrudes into the receiving space when the cover is closed, and which pin-shaped active element moves when the cover is moved relative to the holding cage. When it can act on the dirt in the holding space.

在吸尘器运行时，在容纳笼的容纳空间中收集有脏物。当盖打开时，至少一个销形的作用元件在容纳空间中运动，并且销形的作用元件可以作用到被收集的脏物上，并且在一定程度上搅动脏物。During operation of the vacuum cleaner, dirt collects in the receiving space of the receiving cage. When the lid is opened, at least one pin-shaped active element moves in the receiving space and can act on the collected dirt and stir it to a certain extent.

由此，使得结块的污物例如松动。使得排空容纳笼由此得到简化，这是因为在针对排空过程打开盖时作用到脏物上，并且使该脏物松动。As a result, agglomerated dirt, for example, is loosened. This simplifies the emptying of the holding cage, since when the lid is opened for the emptying process the dirt acts on it and loosens it.

尤其是也可行的是，至少一个销形的作用元件相应地构造有相应大的表面，从而使脏物或脏物的一部分挂在销形的作用元件上，并且由此在一定程度上从容纳笼拉出。In particular, it is also possible that the at least one pin-shaped active element is correspondingly configured with a correspondingly large surface, so that dirt or a part of the dirt hangs on the pin-shaped active element and thus is protected to a certain extent from the accommodating cage pulled out.

至少一个销形的作用元件作为凸片尤其被安置在盖上。由此，盖进而预分离器可以以简单的方式构造。In particular, at least one pin-shaped active element is arranged as a tab on the cover. As a result, the cover and thus the pre-separator can be constructed in a simple manner.

十分特别有利的是，当盖被固定在容纳笼上时，在盖进行松开运动的情况下，至少一个销形的作用元件在容纳空间中运动。由此，使盖的反正是必要的松开运动用于作用到容纳空间中的收集的脏物上。It is very particularly advantageous if at least one pin-shaped engagement element is moved in the receiving space during a release movement of the cover when the cover is fastened to the receiving cage. In this way, the loosening movement of the cover which is necessary anyway is used to act on the dirt collected in the receiving space.

在一种实施例中，至少一个作用元件呈楔形地和/或多齿尖地构造。由此可以有效地作用到脏物上。In one embodiment, at least one active element is wedge-shaped and/or multi-toothed. In this way, dirt can be effectively acted upon.

有利地，在盖上布置有用于抽吸流管路的接口。由此可以实现高的功能整合。本来必要的接口被整合到盖中。Advantageously, a connection for the suction flow line is arranged on the cover. A high level of functional integration can thereby be achieved. The otherwise necessary interfaces are integrated into the cover.

此外有利的是，盖具有下侧，其在盖闭合时面对容纳空间，并且至少一个销形的作用元件在下侧上横向于该下侧地定向。由此可以以简单的方式实现销形的作用元件，其固定在盖上，并且在盖闭合时探伸到容纳空间中。It is also advantageous if the cover has an underside which faces the receiving space when the cover is closed, and at least one pin-shaped engagement element is oriented on the underside transversely to the underside. In this way, a pin-shaped active element can be realized in a simple manner, which is fastened to the cover and protrudes into the receiving space when the cover is closed.

有利的是，容纳笼构造为网格笼，其尤其是具有底部器壁和布置在底部器壁上的侧器壁的网格结构。由此，(载有脏物的)抽吸流可以以简单的方式被导引穿过预分离器。网眼结构，例如织物，尤其是布置在网格笼的开口(底部器壁和侧器壁)上。网眼结构的网眼宽度于是确定了在容纳笼中收集哪些颗粒大小并且哪些颗粒大小能够穿透。It is advantageous if the receiving cage is configured as a grid cage, which in particular has a grid structure with a bottom wall and side walls arranged on the bottom wall. As a result, the (dirt-laden) suction flow can be guided through the pre-separator in a simple manner. A mesh structure, such as a fabric, is arranged in particular on the openings (bottom and side walls) of the mesh cage. The mesh width of the mesh structure then determines which particle sizes are collected in the holding cage and which particle sizes are able to penetrate.

在一种实施例中，盖可以完全从容纳笼松开。由此可以实现简单地排空容纳笼。In one embodiment, the lid is completely releasable from the containment cage. This makes it possible to easily empty the holding cage.

在一种实施例中，盖作为翻转盖被安置在容纳笼上。通过使盖相对于容纳笼翻起而打开盖。盖在此可以持久地被安置在容纳笼上或者其是能松开的。通过翻起，使至少一个销形的作用元件在容纳空间中运动，并且盖的相应的枢转运动导致作用到所收集的脏物上。In one embodiment, the cover is placed on the holding cage as a flip cover. The lid is opened by flipping the lid relative to the holding cage. The cover can be permanently attached to the holding cage or it can be detachable. By tilting up, at least one pin-shaped engagement element is moved in the receiving space, and a corresponding pivoting movement of the cover results in an action on the collected dirt.

在此有利的是，盖具有中间轴线或中间平面，并且至少一个销形的作用元件布置在中间轴线与翻转铰接部之间，并且尤其是与距中间轴线或中间平面相比更靠近翻转铰接部地被安置在盖上。由此可以在相对较大的空间区域内作用到容纳空间中的脏物上。It is advantageous here if the cover has a central axis or a central plane and at least one pin-shaped engagement element is arranged between the central axis and the pivot joint, and in particular closer to the pivot joint than to the central axis or the central plane The ground is placed on the cover. As a result, dirt in the receiving space can be acted on over a relatively large spatial area.

在替选的或组合的实施方式中，盖被构造为转动盖。原则上可以实现的是，盖被构造为单纯的转动盖，或者构造为转动和翻转盖。例如在构造为转动/翻转盖时，为了打开盖首先需要转动运动，其中，然后，盖可以通过翻起而打开，并且例如通过转动运动，使盖联接在翻转铰接部上。In an alternative or combined embodiment, the cover is designed as a swivel cover. In principle, it is possible for the lid to be designed as a purely pivoting lid or as a pivoting and flipping lid. For example, in the case of a swivel/tilt lid, a swivel movement is first required to open the lid, wherein the lid can then be opened by flipping it up and the lid is coupled to the swivel hinge, for example, by the swivel movement.

在设计结构上是简单的实施方式中，盖可以通过卡口装置固定在容纳笼上。由此可以以简单的方式达到固定位置，并且盖可以从固定位置出发以简单的方式打开。In a structurally simple embodiment, the cover can be fastened to the holding cage by means of a bayonet arrangement. The fastening position can thereby be reached in a simple manner, and the cover can be opened in a simple manner starting from the fastening position.

十分特别有利的是，至少一个销形的作用元件在盖转动时在眶式轨迹上运动。由此可以实现有效地作用到容纳空间中的所收集的脏物上。尤其是当设置有多个销形的作用元件时得到有效的混搅。It is very particularly advantageous if at least one pin-shaped active element moves on an orbital path when the cover is turned. An effective action on dirt collected in the receiving space can thus be achieved. Effective mixing is achieved in particular when a plurality of pin-shaped active elements are provided.

在一种实施例中设置有至少两个对置的销形的作用元件。这些作用元件彼此间隔开。由此可以在盖转动时实现大的作用面积。In one embodiment, at least two opposing pin-shaped active elements are provided. These active elements are spaced apart from each other. As a result, a large effective area can be achieved when the cover is turned.

在此有利的是，至少一个销形的作用元件刚性地构造，以便实现有效地作用和尤其是对在容纳空间中收集的脏物的松动。It is advantageous here if the at least one pin-shaped engagement element is of rigid design in order to achieve effective activation and in particular loosening of dirt collected in the receiving space.

在一种实施例中，分离器装置构造为过滤器-分离器装置，过滤器-分离器装置不仅具有针对粗脏物的分离器功能，而且还具有针对细脏物的过滤器功能。分离器装置尤其是多级地构造，并且例如具有针对(细)灰尘的过滤器装置，该过滤器装置后置于预分离器(作为针对粗尘的过滤器和收集器)。分离器装置可以由此节省空间地构造。In one embodiment, the separator device is designed as a filter-separator device, which not only has a separator function for coarse dirt, but also a filter function for fine dirt. The separator device is in particular multi-stage and has, for example, a filter device for (fine) dust which is downstream of the pre-separator (as filter and collector for coarse dust). The separator device can thus be designed in a space-saving manner.

例如，针对(细)灰尘的过滤器装置被构造为筒匣式滤芯。筒匣式滤芯可以由此在紧凑的空间尺寸的情况下实现有效的清洁。For example, filter devices for (fine) dust are designed as cartridge filter inserts. Cartridge filter inserts can thus be effectively cleaned with compact spatial dimensions.

在一种实施例中设置了过滤器盒，其包括过滤器-分离器装置并且可以作为单元运用。例如，过滤器盒于是可以作为单元从吸尘器去除，以便执行排空过程。容纳笼尤其是能松开地(或牢固地)布置在过滤器盒上。容纳笼可以从过滤器盒取出。在松开盖后，可以排空容纳笼。In one embodiment a filter cassette is provided which comprises a filter-separator arrangement and can be operated as a unit. For example, the filter cassette can then be removed as a unit from the vacuum cleaner in order to carry out the emptying process. In particular, the receiving cage can be arranged detachably (or firmly) on the filter cassette. The holding cage can be removed from the filter box. After the lid is loosened, the holding cage can be emptied.

有利的是，过滤器盒具有用于与抽吸机组流体作用连接的接口。由此可以实现紧凑的构造，并且在置入过滤器盒时能够以简单的方式实现与抽吸机组的联接。用于流体作用地联入附着有脏物的抽吸流的接口尤其是在盖上形成。It is advantageous if the filter cassette has a connection for a fluidic connection to the suction unit. This makes it possible to achieve a compact construction and to allow a simple connection to the suction unit when inserting the filter cassette. The connection for the fluidic connection of the dirt-adhered suction flow is formed, in particular, on the cover.

在吸尘器的壳体中尤其是布置有具有分离器装置的能取出的过滤器盒。由此可以以简单的方式执行灰尘排空。此外，过滤器更换可以以简单的方式执行。In particular, a removable filter cassette with a separator device is arranged in the housing of the vacuum cleaner. Dust evacuation can thus be carried out in a simple manner. Furthermore, filter replacement can be performed in a simple manner.

壳体尤其是包括能打开的门，其中，经由门开口，过滤器盒可以从壳体中取出。由此得到简单的排空可能性和再置入可能性。In particular, the housing includes an openable door, wherein the filter cassette can be removed from the housing via the door opening. This results in simple emptying and reinserting possibilities.

接口84与吸嘴接口24协作地如下这样构造，即，使管装置14经由第一管46能够插入在地面吸嘴26的接口区域88上。插入方向(参考在其中管装置14已经插入在接口区域88上的位置)在此尤其平行于第二延伸轴线44。The connection 84 is designed in cooperation with the nozzle connection 24 in such a way that the tube arrangement 14 can be inserted via the first tube 46 onto the connection region 88 of the floor suction nozzle 26 . The insertion direction (referenced to the position in which the tube arrangement 14 has been inserted on the connection region 88 ) is here in particular parallel to the second axis of extension 44 .

地面吸嘴26的壳体66的上侧74具有平坦的区域90(图4)。The upper side 74 of the housing 66 of the floor nozzle 26 has a flat area 90 ( FIG. 4 ).

在上侧74并且尤其是平坦的区域90上布置有第一固定装置92。在壳体12上并且在此是第一壳体侧16上布置有第二固定装置94，第二固定装置用于和地面吸嘴26的第一固定装置92协作。A first fastening device 92 is arranged on the upper side 74 and in particular on the flat region 90 . Arranged on the housing 12 and here on the first housing side 16 is a second fastening device 94 for cooperating with the first fastening device 92 of the floor suction nozzle 26 .

在一种实施例中，第一固定装置92包括一个或多个嵌入凹部96。第二固定装置94包括一个或多个肋状凸起98，其中，肋状凸起如下这样地布置在第二壳体侧18上，即，使肋状凸起在站立位置22下嵌入到所配属的嵌入凹部96中，并且在此使站立位置22稳固。In one embodiment, the first securing device 92 includes one or more insertion recesses 96 . The second fastening device 94 comprises one or more rib-shaped projections 98 , wherein the rib-shaped projections are arranged on the second housing side 18 in such a way that the rib-shaped projections engage in the standing position 22 The associated recess engages in the recess 96 and stabilizes the standing position 22 there.

在站立位置22中，管装置14处于基本位置中，在该基本位置中，管装置14尤其具有沿第二延伸轴线44最小化的长度，并且其中，于是稳固了管装置14的相应的位置。这在下面还将详细描述。尤其地，肋状凸起98和所配属的嵌入凹部96如下这样地构造，即，通过肋状凸起98和嵌入凹部96的相互嵌接产生形状锁合。In standing position 22 , tube arrangement 14 is in a basic position in which, in particular, tube arrangement 14 has a minimized length along second extension axis 44 , and wherein the corresponding position of tube arrangement 14 is then stabilized. This will also be described in detail below. In particular, the rib-shaped projection 98 and the associated engagement recess 96 are designed in such a way that a positive fit is produced by the rib-shaped projection 98 and the engagement recess 96 engaging with each other.

通过第一固定装置92和第二固定装置74的协作防止了吸尘器10在站立位置22中发生倾斜。Tilting of the vacuum cleaner 10 in the standing position 22 is prevented by the cooperation of the first fastening device 92 and the second fastening device 74 .

图5中示意性地示出了第一固定装置92和第二固定装置94的合作。The cooperation of the first fixing device 92 and the second fixing device 94 is schematically shown in FIG. 5 .

吸尘器10具有重心100(图4)。整个机器的重心100位于壳体12内部，并且例如位于抽吸机组32的高度中。The vacuum cleaner 10 has a center of gravity 100 (FIG. 4). The center of gravity 100 of the entire machine is located within the housing 12 and, for example, at the level of the suction unit 32 .

当吸尘器10被竖立在关于重力方向g是水平的面28上时，重心100的投影线沿竖直的方向(平行于重力方向g地)穿过地面吸嘴26，并且例如穿过地面吸嘴26的平坦的区域90。When the vacuum cleaner 10 is erected on a surface 28 that is horizontal with respect to the direction of gravity g, the projection line of the center of gravity 100 passes through the floor suction nozzle 26 in a vertical direction (parallel to the direction of gravity g), and for example passes through the floor suction nozzle 26 for the flat area 90.

在站立位置22中，重心100位于地面吸嘴26上方。由此实现稳定的位置并且使站立位置22稳固。In the standing position 22 the center of gravity 100 is located above the floor nozzle 26 . This achieves a stable position and stabilizes the standing position 22 .

第一固定装置92和第二固定装置94相互匹配地构造，并且尤其地，一个肋状凸起或多个肋状凸起98和所配属的嵌入凹部96或相应的多个嵌入凹部96如下这样地构造，即，斜置10°(尤其是至少10°)不会松开固定，也就是说第一固定装置92与第二固定装置94之间的相应的连接沿所有方向即使在斜度为10°的情况下也都可以保持住。The first fastening device 92 and the second fastening device 94 are designed to match each other, and in particular the rib-shaped projection or the rib-shaped projections 98 and the associated engagement recess 96 or the corresponding engagement recesses 96 are as follows It is constructed in such a way that an inclination of 10° (in particular at least 10°) does not loosen the fixation, that is to say that the corresponding connection between the first fixing device 92 and the second fixing device 94 is in all directions even at an inclination of It can also be maintained under the situation of 10°.

只有当像上面提到的那样，管装置14被移入时(图1至4)，第一固定装置92才与第二固定装置94合作。Only when, as mentioned above, the tube arrangement 14 is moved in ( FIGS. 1 to 4 ) does the first fixing device 92 cooperate with the second fixing device 94 .

当从此出发，在吸嘴接口24与第一壳体侧16之间的间距增大时，则第二固定装置94和第一固定装置92可以不再相互作用。If, proceeding from this, the distance between the nozzle connection 24 and the first housing side 16 increases, then the second fastening device 94 and the first fastening device 92 can no longer interact.

在替选的或组合的实施方式中(图6)，在地面吸嘴26的上侧74并且尤其是在平坦的区域90上布置有(至少一个)配对元件102。在壳体12的第一壳体侧16布置有(至少一个)相对应的磁体元件104。In an alternative or combined embodiment ( FIG. 6 ), (at least one) counter element 102 is arranged on upper side 74 of floor suction nozzle 26 and in particular on flat region 90 . A (at least one) corresponding magnet element 104 is arranged on the first housing side 16 of the housing 12 .

当吸尘器10处于站立位置22中，并且从待清洁的面28抬起时，这例如可以用于使地面吸嘴26不会倾离壳体12。This can be used, for example, to prevent the floor nozzle 26 from tipping away from the housing 12 when the vacuum cleaner 10 is in the standing position 22 and is raised from the surface 28 to be cleaned.

原则上，由配对元件102和磁体元件104构成的组合也可以用于通过如下方式力锁合地固定站立位置22，即，使地面吸嘴26的壳体66能松开地固定在吸尘器10的壳体12上。In principle, the combination of the counter element 102 and the magnet element 104 can also be used to fasten the standing position 22 in a non-positive manner in such a way that the housing 66 of the floor suction nozzle 26 can be fixed releasably on the bottom of the vacuum cleaner 10. on the housing 12.

在一种实施例中设置的是，地面吸嘴26为了在硬面或地毯面上运行是能切换的，其中，一个或多个支撑元件80不管在针对硬面使用的情况下是滚子106(图4)，还是在地毯面上使用的情况下是滑动元件，都尤其是能转换的。In one embodiment, it is provided that the floor suction nozzle 26 is switchable for operation on hard surfaces or carpeted surfaces, wherein one or more support elements 80 are rollers 106 regardless of whether they are used on hard surfaces.

The door 112 covers a door opening 114 behind which the separator device 30 is positioned in the housing 12 .

在一种实施例(也参见图8)中，门112牢固地固定在分离器装置30上。当分离器装置30被正确地定位在壳体12中时，则门112“自动”封闭门开口。In one embodiment (see also FIG. 8 ), the door 112 is fixedly secured to the separator device 30 . When the separator device 30 is properly positioned in the housing 12, then the door 112 "automatically" closes the door opening.

过滤器盒116为此包括具有器壁142的壳体140。在器壁142的内侧上布置有接片元件144，其离开器壁142地探伸到壳体140的内部空间中。For this purpose, filter cassette 116 includes a housing 140 with a wall 142 . A web element 144 is arranged on the inner side of the wall 142 , which protrudes away from the wall 142 into the interior of the housing 140 .

环圈138具有环绕的凸缘146，其在容纳笼126定位在过滤器盒116上时的贴靠区域中贴靠在接片元件144上。通过凸缘146在接片元件144上的贴靠阻止了容纳笼126的“向下掉落”。The collar 138 has a circumferential collar 146 , which bears against the web element 144 in the contact region when the receiving cage 126 is positioned on the filter cassette 116 . A “falling down” of the receiving cage 126 is prevented by the abutment of the flange 146 on the web element 144 .

此外，环圈138具有弓形部148，其在针对接片元件144的贴靠区域之外地被安置在凸缘146上。在弓形部148与容纳笼126之间形成自由空间150。弓形部148朝容纳笼126的底部152的方向离开侧134地探伸。Furthermore, the collar 138 has a bow 148 which is seated on the collar 146 outside of the area of contact with the web element 144 . A free space 150 is formed between the bow 148 and the receiving cage 126 . The bow 148 protrudes away from the side 134 in the direction of the bottom 152 of the receiving cage 126 .

通过弓形部148，环圈138和进而是容纳笼126可以倒扣到器壁142上；当容纳笼126被固定在过滤器盒116上时，器壁142的区域154探入到自由空间150中。通向弓形部148的过渡区域贴靠在器壁的端侧156上。The ring 138 and thus the receiving cage 126 can be snapped upside down on the wall 142 via the bow 148 ; when the receiving cage 126 is fixed on the filter box 116 , a region 154 of the wall 142 protrudes into the free space 150 . The transition region to the bow 148 bears against the end face 156 of the wall.

经由环圈138，容纳笼126挂入过滤器盒116的壳体140中。通过凸缘146和弓形部148阻止向下的可运动性。经由弓形部148阻止了沿横向的方向(具有一定的间隙)的可运动性。Via collar 138 , receiving cage 126 is suspended into housing 140 of filter cassette 116 . The downward mobility is prevented by the flange 146 and the bow 148 . Mobility in the transverse direction (with some play) is prevented by the bow 148 .

容纳笼126可以经由环圈138以简单的且尤其是无工具的方式通过在壳体140上挂入而固定在过滤器盒116上，并且相应地以简单的方式无工具地取出。The receiving cage 126 can be fastened to the filter box 116 via the ring 138 in a simple and in particular tool-free manner by being hooked onto the housing 140 , and correspondingly can be removed in a simple and tool-free manner.

凸缘146的针对接片元件144的贴靠区域尤其是与弓形部148在直径上对置地布置。The contact region of the collar 146 for the web element 144 is in particular arranged diametrically opposite the bow 148 .

在一种实施例(图8至10)中，盖132构造为翻转盖。在环圈138上布置有翻转铰接部158。翻转铰接部158尤其是与弓形部148对置地布置。在该区域中，环圈138基于弓形部148而被加强，并且翻转铰接部158可以由此以简单的方式在该区域中被整合到环圈138中。In one embodiment ( FIGS. 8 to 10 ), the cover 132 is configured as a flip cover. A pivot joint 158 is arranged on the collar 138 . In particular, the pivot joint 158 is situated opposite the bow 148 . In this region, the ring 138 is reinforced by the bow 148 , and the pivot joint 158 can thus be easily integrated in this region into the ring 138 .

销形的作用元件160被安置在盖上。盖132具有下侧162，其在盖闭合时面对容纳空间130并且在此面对底部152。A pin-shaped active element 160 is mounted on the cover. The lid 132 has an underside 162 which, when the lid is closed, faces the receiving space 130 and here faces the bottom 152 .

销形的作用元件160被安置在下侧162上，横向地探伸超出该下侧。在盖132闭合时，销形的作用元件160探入容纳空间130中。The pin-shaped active element 160 is arranged on an underside 162 beyond which it protrudes transversely. When the cover 132 is closed, the pin-shaped active element 160 protrudes into the receiving space 130 .

盖132具有中间线164和中间平面166。销形的作用元件160被安置在中间线164或中间平面166与翻转铰接部158之间。销形的作用元件尤其是与距中间线164相比更靠近翻转铰接部158。Cover 132 has a median line 164 and a median plane 166 . The pin-shaped active element 160 is arranged between a center line 164 or a center plane 166 and the pivot joint 158 . In particular, the pin-shaped active element is closer to the pivot joint 158 than to the center line 164 .

销形的作用元件160如下这样地构造，即，在打开盖132时，通过翻起使销形的作用元件运动穿过容纳空间130(参见图8和10)，并且在此不擦碰容纳笼126的器壁，或者说盖132的运动没有由于销形的作用元件160与这样的器壁的发生碰撞而受到限制。The pin-shaped active element 160 is designed in such a way that when the cover 132 is opened, it is moved through the receiving space 130 by being tilted up (see FIGS. 8 and 10 ) without rubbing against the receiving cage. The wall 126, or the movement of the cover 132, is not restricted by the collision of the pin-shaped active element 160 with such a wall.

销形的作用元件160尤其呈楔形地构成(参见图10)，其具有第一侧168a和对置的第二侧168b，它们彼此呈锐角度定向。The pin-shaped active element 160 is in particular wedge-shaped (see FIG. 10 ) and has a first side 168 a and an opposite second side 168 b , which are oriented at an acute angle to one another.

在吸尘器10运行时，脏物被收集在预分离器122的容纳空间130中。During operation of the vacuum cleaner 10 , dirt is collected in the receiving space 130 of the pre-separator 122 .

具有预分离器122的过滤器盒116可以从壳体12中取出。Filter cassette 116 with pre-separator 122 can be removed from housing 12 .

具有盖132的容纳笼126是能取出的。容纳笼可以能松开地固定在过滤器盒116上。The containment cage 126 with the lid 132 is removable. The containment cage may be releasably fastened to the filter box 116 .

在替选的实施方式中，盖没有直接固定在容纳笼126上，而是在容纳笼126之外地固定在过滤器盒116上。容纳笼可以由此在没有盖的情况下取出。In an alternative embodiment, the cover is not attached directly to the receiving cage 126 , but is attached to the filter box 116 outside of the receiving cage 126 . The holding cage can thus be removed without a cover.

当盖132通过翻起而打开时，销形的作用元件160运动穿过容纳空间130。当容纳空间130在相应的范围内被填充以脏物时，销形的作用元件160运动穿过脏物。该脏物被弄松。由此使排空容纳笼126变得容易。When the cover 132 is opened by being folded up, the pin-shaped active element 160 is moved through the receiving space 130 . When the receiving space 130 is filled with dirt to a certain extent, the pin-shaped active element 160 is moved through the dirt. The dirt is loosened. This makes it easier to empty the receiving cage 126 .

此外，销形的作用元件160也可以按照铲子的类型还携带有脏物，以便同样使排空变得容易。Furthermore, the pin-shaped active element 160 can also carry dirt, in the manner of a shovel, in order to likewise facilitate emptying.

在另外的实施例中，容纳笼126’设置有盖170(图11至14)。容纳笼126’原则上和容纳笼126构造相同，其中，容纳笼126’具有环圈172。In a further embodiment, the containment cage 126' is provided with a cover 170 (Figs. 11 to 14). The receiving cage 126' is basically constructed identically to the receiving cage 126, wherein the receiving cage 126' has a ring 172.

盖170构造为转动盖，其可以经由卡扣锁闭与容纳笼126’固定。The cover 170 is configured as a swivel cover, which can be fixed to the receiving cage 126' via a snap lock.

布置于容纳笼126’的环圈172包括角舌板174。在所示的实施例中，四个角舌板以90°的角度间距设置。The collar 172 disposed on the containment cage 126' includes a tongue 174. In the exemplary embodiment shown, the four corner tongues are arranged at an angular distance of 90°.

角舌板174具有凹部176，盖170以边缘区域178探入在其中。只要该边缘区域178探入凹部176中，那么角舌板174就防止了盖170向上离开容纳笼126’的底部152’地取下。The gusset 174 has a recess 176 into which the cover 170 protrudes with an edge region 178 . As long as this edge region 178 protrudes into the recess 176, the gusset 174 prevents the cover 170 from being removed upwards away from the bottom 152' of the receiving cage 126'.

盖170本身设有与角舌板174相对应的凹部180。在所示的实施例中，四个凹部180以90°的角度间距设置。The cover 170 itself is provided with a recess 180 corresponding to the gusset 174 . In the illustrated embodiment, four recesses 180 are arranged at an angular distance of 90°.

当凹部180位于角舌板174的凹部176中时，相应的角舌板174不再阻止盖170向上的可抬起性，也就是是说，当凹部180与角舌板174相对应时，盖170可以向上被抬起。When the recess 180 is located in the recess 176 of the tongue 174, the corresponding tongue 174 no longer prevents the upward liftability of the lid 170, that is to say, when the recess 180 corresponds to the tongue 174, the lid 170 can be lifted upwards.

在盖170的锁定位置中，其如下这样地被定位，即，使边缘区域178相应地位于角舌板174里面。In the locked position of the cover 170 , it is positioned such that the edge region 178 is correspondingly located inside the gusset 174 .

在一种实施例中，盖170如下这样地构造，即，它在盖170上具有侧向的止挡部182，侧向的止挡部能够止挡到角舌板174上。由此阻止盖170相对于环圈172的进一步转动。从角舌板174贴靠在侧向的止挡部182上起，盖170可以如下这样地转动，即，使凹部180与角舌板174的凹部176相对应。盖170于是可以被抬起。In one exemplary embodiment, the cover 170 is designed in such a way that it has a lateral stop 182 on the cover 170 which can stop against the gusset 174 . Further rotation of the cover 170 relative to the collar 172 is thereby prevented. As soon as the gusset 174 rests against the lateral stop 182 , the cover 170 can be turned such that the recess 180 corresponds to the recess 176 of the gusset 174 . Cover 170 can then be lifted.

在盖170上，在下侧184上被安置有多个销形的的作用元件186。这些销形的作用元件尤其是作为凸片被安置在盖170上。A plurality of pin-shaped active elements 186 are arranged on the underside 184 on the cover 170 . These pin-shaped active elements are mounted on the cover 170 , in particular as lugs.

在盖170闭合时，销形的作用元件186沉到容纳空间130中。When the cover 170 is closed, the pin-shaped active element 186 sinks into the receiving space 130 .

销形的作用元件在此可以够到底部152’。The pin-shaped active element can reach the bottom 152' here.

尤其是在直径上对置地设置有多个销形的作用元件186。In particular, a plurality of pin-shaped active elements 186 are arranged diametrically opposite each other.

销形的作用元件186在此可以多齿尖地构造，或者可以为了增大表面例如作为成束的多个间隔开的或彼此连接的细管制成。The pin-shaped active element 186 can be multi-cusp in this case, or it can be produced, for example, as a bundle of several thin tubes spaced apart or connected to one another in order to increase the surface area.

根据针对抽吸流管路的接口136，在盖170上设置有接口188。According to the connection 136 for the suction flow line, a connection 188 is provided on the cover 170 .

为了排空填充有脏物的容纳笼126’而去除盖170。为此，盖170转动。通过将销形的作用元件186转动到容纳空间130中，使脏物松动并且/或者使脏物保留附着在销形的作用元件186上。Lid 170 is removed to empty containment cage 126' filled with dirt. For this, the cover 170 is rotated. By turning the pin-shaped active element 186 into the receiving space 130 , dirt is loosened and/or remains attached to the pin-shaped active element 186 .

当盖170被取下时，容纳笼126’于是可以轻易被排空，或者可以使附着在销形的作用元件186上的脏物被抖落。When the cover 170 is removed, the holding cage 126' can then be easily emptied, or dirt adhering to the pin-shaped active element 186 can be shaken off.

通过在盖132或盖170中的销形的作用元件186或160，预分离器122的容纳笼126或126’可以在从壳体12取出后以简单的方式被排空。通过在打开盖132时或在打开盖170时销形的作用元件160或销形的作用元件186的相对运动，“搅铲”在容纳笼126或126’中的脏物，并且由此使脏物结块松动。By means of the pin-shaped active element 186 or 160 in the cover 132 or cover 170, the receiving cage 126 or 126' of the pre-separator 122 can be emptied in a simple manner after removal from the housing 12. By the relative movement of the pin-shaped active element 160 or the pin-shaped active element 186 when the lid 132 is opened or when the lid 170 is opened, the dirt in the holding cage 126 or 126 ′ is "scrambled" and thus the dirt The agglomeration loosens.

像上面已经提到的那样，销形的作用元件186也可以用作针对脏物的附着元件。As already mentioned above, the pin-shaped active element 186 can also be used as an attachment element for dirt.

针对灰尘的过滤器装置124被定位在过滤器盒116的壳体140中，过滤器装置作为过滤器-分离器装置的第二分级(“细级”)后置于预分离器122(“粗级”)。过滤器装置尤其是能松开地定位在壳体140中。A filter unit 124 for dust is positioned in the housing 140 of the filter box 116, the filter unit being placed after the pre-separator 122 (“coarse class”) as a second stage (“fine class”) of the filter-separator unit. class"). The filter device is in particular detachably positioned in the housing 140 .

在一种实施例中，在器壁142上布置有相应的针对过滤器装置124的舌形的嵌入器件190，以便能够实现清洁壳体140中的过滤器装置124。In one exemplary embodiment, corresponding tongue-shaped insertion means 190 for the filter device 124 are arranged on the wall 142 in order to enable cleaning of the filter device 124 in the housing 140 .

在一种实施例中，过滤器装置124构造为筒匣式滤芯192。In one embodiment, the filter device 124 is configured as a cartridge filter element 192 .

过滤器装置124包括过滤器元件194，其例如呈管形地构成，并且具有过滤器褶皱部198。过滤器褶皱部198被安置在底部196上，经由底部196，过滤器装置124又例如经由卡口式连接而固定在壳体上。The filter device 124 includes a filter element 194 which is, for example, tubular in design and has filter folds 198 . The filter folds 198 are seated on a bottom 196 , via which the filter device 124 is in turn fastened to the housing, for example via a bayonet connection.

过滤器元件194中的被过滤器褶皱部198的过滤材料包围的开口和底部196中的开口与过滤器盒116的输出接口120相对应。例如，输出接口120于是经由过滤器装置124形成在底部196上。The openings in the filter element 194 surrounded by the filter material of the filter folds 198 and the openings in the bottom 196 correspond to the outlet connections 120 of the filter cassette 116 . For example, the output interface 120 is then formed on the bottom 196 via the filter device 124 .

过滤器元件194关于其内部空间朝预分离器122闭合。过滤器褶皱部198之间的空间朝预分离器122敞开。The filter element 194 is closed towards the pre-separator 122 with respect to its interior space. The spaces between the filter pleats 198 are open to the pre-separator 122 .

抽吸流(在图9中用附图标记200指示)于是进入过滤器装置124中，并且在那里在过滤器褶皱部198之间经过过滤器元件194的端侧202。The suction flow (indicated by reference numeral 200 in FIG. 9 ) then enters the filter device 124 and there passes the end face 202 of the filter element 194 between the filter folds 198 .

抽吸流穿流过过滤器褶皱部198的过滤材料，其中，灰尘颗粒没有穿透过过滤器元件194，也就是说基本上被挂留在过滤器元件194上。The suction flow passes through the filter material flowing through the filter folds 198 , wherein the dust particles do not penetrate through the filter element 194 , that is to say are essentially retained on the filter element 194 .

在输出接口120上提供如下抽吸流，其灰尘载量与联入到输入接口118中的抽吸流相比所载灰尘少了很多。A suction flow is provided at the outlet connection 120 , which is much less dust-laden than the suction flow fed into the inlet connection 118 .

在过滤器元件194在壳体140中转动时，嵌入器件190作用到过滤器褶皱部198上，并且使过滤器褶皱部“抖动”，由此，使附着的灰尘颗粒松动。由此，在排空过滤器盒116时可以减少对周围环境的灰尘负载。When the filter element 194 is rotated in the housing 140 , the insert means 190 act on the filter folds 198 and “flutter” the filter folds, thereby loosening the adhering dust particles. As a result, the dust load on the surrounding environment can be reduced when emptying the filter cassette 116 .

当过滤器盒116从吸尘器10的壳体12去除时，像上面提到的那样，容纳笼126或126’可以被取下并且排空。When the filter cartridge 116 is removed from the housing 12 of the vacuum cleaner 10, the containment cage 126 or 126' can be removed and emptied as mentioned above.

在需要时，尤其经由底部196卡入壳体140中的过滤器装置124(尤其是在作为筒匣式滤芯192的构造中)可以取下并且更换或抖出，其中，灰尘于是可以经由端侧202从过滤器装置排空。If necessary, the filter device 124 snapped into the housing 140 , in particular via the bottom 196 (especially in the configuration as a cartridge filter insert 192 ), can be removed and replaced or shaken out, wherein the dust can then be removed via the end side. 202 is drained from the filter unit.

抽吸机组32具有抽吸接套204。过滤器盒116的输出接口120与该抽吸接套104流体作用地连接。The suction unit 32 has a suction nipple 204 . An outlet connection 120 of the filter cassette 116 is fluidically connected to the suction nipple 104 .

在吸尘器10的壳体12中，在抽吸机组32后面布置有排气过滤器206。排气过滤器206尤其被用于过滤出马达磨损粒。An exhaust filter 206 is arranged downstream of the suction unit 32 in the housing 12 of the vacuum cleaner 10 . Exhaust filter 206 is used, among other things, to filter out motor wear particles.

给风扇马达34配属流动转向元件208。流动转向元件208尤其是构造为罩。A flow deflection element 208 is assigned to the fan motor 34 . The flow deflection element 208 is designed in particular as a cap.

在一种实施例中，流动转向元件208围绕风扇马达34定位在过滤器盒116与排气过滤器206之间。In one embodiment, flow diversion element 208 is positioned around fan motor 34 between filter box 116 and exhaust filter 206 .

原则上也可行的是，相应的流动转向元件后置于排气过滤器206。In principle, it is also possible to arrange corresponding flow deflection elements downstream of the exhaust filter 206 .

流动转向元件具有相应的器壁，其限定了具有相反的主流动方向的第一流动区域210和第二流动区域212。例如，第二流动区域212呈环形地包围第一流动区域210。The flow diverting elements have respective walls which define a first flow area 210 and a second flow area 212 with opposite main flow directions. For example, the second flow area 212 surrounds the first flow area 210 annularly.

在第一流动区域210与第二流动区域212之间的过渡部214上布置有抗噪的壁，其由抗噪的材料制成，其具有至少94％的噪音反射率。Arranged at the transition 214 between the first flow area 210 and the second flow area 212 is a noise-resistant wall made of a noise-resistant material which has a noise reflection rate of at least 94%.

在过渡部上的壁尤其是呈环形的。The wall at the transition is in particular annular.

过渡部在此形成在围绕风扇马达34的区域中。The transition is here formed in the region surrounding fan motor 34 .

在一种实施例中，在过渡部214上布置有泡沫物环。In one embodiment, a ring of foam is disposed on the transition portion 214 .

壳体12在排气过滤器206的区域中具有能封闭的盖216，以便能够实现接近排气过滤器214，用以更换排气过滤器。Housing 12 has a sealable cover 216 in the region of exhaust filter 206 in order to allow access to exhaust filter 214 for exchanging the exhaust filter.

盖216例如与第一壳体侧16相邻地布置。The cover 216 is arranged, for example, adjacent to the first housing side 16 .

在壳体12中，在壳体器壁38与过滤器盒116和抽吸机组32之间形成空间218，其沿第一延伸轴线20延伸，并且基本上占据排气过滤器206与第二壳体侧18之间的总壳体高度。In the housing 12, a space 218 is formed between the housing wall 38 and the filter box 116 and the suction unit 32, which extends along the first extension axis 20 and substantially occupies the exhaust gas filter 206 and the second housing. Overall shell height between body sides 18 .

在排气过滤器206后，在壳体12中形成空间220，然后，该空间过渡为空间218。在第一壳体侧16与排气过滤器206之间的空间220被用作用于流动转向到空间218中的转向区域。After the exhaust filter 206 , a space 220 is formed in the housing 12 , which then transitions into the space 218 . The space 220 between the first housing side 16 and the exhaust air filter 206 is used as a diversion area for diverting the flow into the space 218 .

在壳体器壁38上布置有多个开口222，其中，开口沿平行于第一延伸轴线20的方向间隔开地布置。A plurality of openings 222 are arranged on the housing wall 38 , the openings being arranged at intervals in a direction parallel to the first extension axis 20 .

开口222与外部空间流体作用地连接。抽吸机组32的是已清洁的空气的排气可以经由开口222从空间218逸出进入到外部空间中。Opening 222 is fluidically connected to the exterior. Exhaust air from the suction unit 32 , which is cleaned air, can escape from the space 218 into the exterior space via the opening 222 .

在开口222上，尤其是在壳体里面分别是开放式多孔的结构224，例如形式为泡沫元件。On the openings 222 , especially inside the housing, there is respectively an open porous structure 224 , for example in the form of a foam element.

在一种实施例中，在空间220中布置有开放式多孔的结构，其例如通过泡沫形成。In one embodiment, an open porous structure is arranged in space 220 , which is formed, for example, by foam.

在吸尘器10运行时，针对抽吸流的在吸尘器10上的流动路径226包括第一区域228，其位于管装置14中。载有脏物的抽吸流通过管装置14中的第一区域228流向连接管58。During operation of the vacuum cleaner 10 , the flow path 226 for the suction flow on the vacuum cleaner 10 includes a first region 228 which is located in the pipe arrangement 14 . The dirt-laden suction flow flows through the first region 228 in the pipe arrangement 14 to the connecting pipe 58 .

在该第一区域228中流动的主流动方向在此基本上平行于第二延伸轴线44。The main flow direction of the flow in this first region 228 is here substantially parallel to the second axis of extension 44 .

在壳体12中，在壳体接口56与排气过滤器206之间形成流动路径226的第二区域230。A second region 230 of the flow path 226 is formed in the housing 12 between the housing connection 56 and the exhaust gas filter 206 .

在连接管58上实现从第一区域228到第二区域230的流动的转向。The deflection of the flow from the first region 228 to the second region 230 takes place at the connecting pipe 58 .

在第二区域230中，主流动方向基本上平行于第一延伸轴线20，并且与第一区域228中的主流动方向相反。In the second region 230 the main flow direction is substantially parallel to the first extension axis 20 and opposite to the main flow direction in the first region 228 .

在风扇马达34上的流动转向元件208在此在第二区域230内实现流动换向，其尤其是用于减小噪音排放。The flow deflection element 208 on the fan motor 34 here implements a flow reversal in the second region 230 , which serves in particular to reduce noise emissions.

第三区域232通过空间218形成。抽吸机组32的是已清洁的空气的排气在第三区域232中流动。在第三区域232中，主流动方向至少大致平行于第一延伸轴线20，并且该主流动方向平行于第一区域228中的主流动方向，或与第二区域230中的主流动方向相反。The third area 232 is formed by the space 218 . The cleaned air exhaust of the suction unit 32 flows in the third region 232 . In the third region 232 the main flow direction is at least approximately parallel to the first axis of extension 20 and is either parallel to the main flow direction in the first region 228 or opposite to the main flow direction in the second region 230 .

空间220用作用于使从第二区域230到第三区域232的流动转向的转向区域。The space 220 serves as a turning area for turning the flow from the second area 230 to the third area 232 .

在图2中示出了流动路径。The flow paths are shown in FIG. 2 .

穿行过流动路径236的路程在数量级中是壳体12的高度大约三倍，也就是附着有脏物的抽吸流首先流过第二区域228，随后流过第二区域230，在其中进行清洁，并且然后，更干净的排气流穿流过第三区域232并且排出到周围环境中。The path traversed by the flow path 236 is in the order of magnitude approximately three times the height of the housing 12 , ie the suction flow laden with dirt first flows through the second area 228 and then through the second area 230 , where cleaning takes place. , and then the cleaner exhaust stream flows through the third region 232 and is expelled into the ambient environment.

通过该较大的流动路径，基于相应的流动行程可以实现低的噪音排放。Due to the larger flow path, low noise emissions can be achieved due to the corresponding flow path.

流动转向元件208利用过渡部214的相应的构造同样提供了低的噪音排放。A corresponding configuration of the flow deflection element 208 with the transition 214 likewise provides low noise emissions.

空气流通过流动转向元件208效率适中地转向，尤其是用来降低噪音排放。The air flow is moderately efficiently deflected by the flow deflection element 208 , in particular to reduce noise emissions.

管装置14是能伸缩的(图15至25)。管装置14为此包括第三管52，其牢固地装配在壳体器壁38上。第三管52具有沿第二延伸轴线44的延伸度。第三管52尤其是刚性地构造。The tube arrangement 14 is telescopic (Figs. 15 to 25). For this purpose, the pipe arrangement 14 comprises a third pipe 52 which is firmly mounted on the housing wall 38 . The third tube 52 has an extent along the second axis of extension 44 . The third tube 52 is in particular of rigid design.

在第三管中布置有第二管48，并且在此以能沿第二延伸轴线44的方向纵向移动的方式引导。第二管48同样刚性地构造。其尤其是以圆筒的形式构造。相应地，第三管52的内部空间是(空心)圆柱形的。A second tube 48 is arranged in the third tube and is guided longitudinally displaceably in the direction of the second extension axis 44 . The second tube 48 is also rigidly constructed. It is in particular configured in the form of a cylinder. Accordingly, the inner space of the third tube 52 is (hollow) cylindrical.

第一管46以能在第二延伸轴线44上纵向移动的方式布置在第二管48中。第一管46圆筒状地构造。第二管48相应地具有(空心)圆柱形的内部空间。The first tube 46 is arranged longitudinally displaceable in the second extension axis 44 in the second tube 48 . The first tube 46 is designed cylindrically. The second tube 48 accordingly has a (hollow) cylindrical interior.

吸嘴接口24布置在第一管46上。The nozzle connection 24 is arranged on the first tube 46 .

第二管48相对于第三管52的相应的相对定位能够以能锁定的方式调整。相应地，第一管46相对第二管48(进而也是相对第三管52)的定位能够以能锁定的方式调整。The corresponding relative positioning of the second tube 48 with respect to the third tube 52 can be adjusted in a lockable manner. Accordingly, the positioning of the first tube 46 relative to the second tube 48 (and thus also relative to the third tube 52 ) can be adjusted in a lockable manner.

给管装置14配属第一锁定装置240(参见例如图19)，第一锁定装置在第一管46与第二管48之间起作用，并且在锁定位置中，第一管46紧固在第二管48上。该锁定位置是能松开的。The pipe arrangement 14 is assigned a first locking device 240 (see eg FIG. 19 ), which acts between the first pipe 46 and the second pipe 48 and which, in the locked position, secures the first pipe 46 to the second pipe. On the two pipes 48. The locked position is releasable.

此外，给管装置14配属第二锁定装置242，第二锁定装置242在第三管52与第二管48之间起作用。第二锁定装置242在锁定位置中将第二管48紧固在第三管52上。第二锁定装置242的该锁定位置是能松开的。Furthermore, the pipe arrangement 14 is assigned a second locking device 242 which acts between the third pipe 52 and the second pipe 48 . The second locking means 242 secures the second tube 48 on the third tube 52 in the locked position. This locking position of the second locking device 242 is releasable.

此外，给管装置配属第三锁定装置244。该第三锁定装置244在第一管46、第二管48与第三管52之间起作用。在第三锁定装置244的能松开的锁定位置中，该第三锁定装置将第二管48紧固在第三管52上。该锁定位置能松开到解锁位置。在第三锁定装置244的解锁位置中，第二管相对第三管52的能移动性得到释放，但其中，通过第二锁定位置242可以使第二管48相对第三管52的特定的定位能被紧固。Furthermore, a third locking device 244 is assigned to the pipe arrangement. This third locking device 244 acts between the first tube 46 , the second tube 48 and the third tube 52 . In the releasable locking position of the third locking device 244 , it fastens the second tube 48 to the third tube 52 . The locked position can be released to the unlocked position. In the unlocked position of the third locking device 244 , the movability of the second tube relative to the third tube 52 is released, but wherein a specific positioning of the second tube 48 relative to the third tube 52 is possible via the second locking position 242 can be fastened.

从第三锁定装置244的锁定位置到解锁位置的过渡经由第一管46预定。在一种实施方式中，第一管46相对第二管48的定位确定了从第三锁定装置244的锁定位置到解锁位置的过渡。The transition from the locked position to the unlocked position of the third locking device 244 is predetermined via the first tube 46 . In one embodiment, the positioning of the first tube 46 relative to the second tube 48 determines the transition from the locked position to the unlocked position of the third locking device 244 .

在另外的实施例中，力作用确定了该过渡。In other embodiments, force effects determine the transition.

第一锁定装置240包括第一探入元件246。第一探入元件246例如是球体或滚子。The first locking device 240 includes a first penetrating element 246 . The first penetrating element 246 is, for example, a ball or a roller.

在第一管46上，间隔开地沿第二延伸轴线44的方向布置有第一凹部248，也参见图15(a)、15(b)和16。First recesses 248 are arranged at intervals in the direction of the second extension axis 44 on the first tube 46 , see also FIGS. 15( a ), 15 ( b ) and 16 .

在一种实施例中，在第一管46上布置有三个间隔开的第一凹部248。In one embodiment, three spaced apart first recesses 248 are disposed on the first tube 46 .

与吸嘴接口24最接近的第一凹部248a在此限定了第一管46相对壳体12的定位，并且进而限定了针对站立位置22的吸嘴接口24的定位。当第一探入元件246探入第一凹部248a中，并且第一锁定装置240被锁定时，则实现了吸嘴接口24相对第一壳体侧16的定位，在其中，第一固定装置92和第二固定装置94可以相互协作，以便固定站立位置22。The first recess 248 a closest to the nozzle interface 24 here defines the positioning of the first tube 46 relative to the housing 12 and thus defines the positioning of the nozzle interface 24 for the standing position 22 . When the first protruding element 246 protrudes into the first recess 248a and the first locking device 240 is locked, the positioning of the nozzle connection 24 relative to the first housing side 16 is achieved, wherein the first fixing device 92 and the second fixing device 94 may cooperate with each other in order to fix the standing position 22 .

该状态在图1至4中示出。This state is shown in FIGS. 1 to 4 .

第一锁定装置240此外还具有能运动的第一阻止元件250(参见例如图19)。该能运动的第一阻止元件250具有针对第一探入元件246的贴靠区域252。当该贴靠区域252位于第一探入元件246上方时，第一探入元件246由此保持在相应的第一凹部248中，并且建立锁定位置。The first locking device 240 also has a first movable blocking element 250 (see eg FIG. 19 ). The first movable blocking element 250 has an abutment region 252 for the first penetrating element 246 . When the contact region 252 is located above the first penetrating element 246 , the first penetrating element 246 is thus held in the corresponding first recess 248 and the locked position is established.

在图19中示出了第一锁定装置240的锁定位置。The locked position of the first locking device 240 is shown in FIG. 19 .

与贴靠区域252相邻地，第一阻止元件250具有第一容纳部254。第一容纳部254面对贴靠区域252地具有斜切的器壁256。Adjacent to the contact region 252 , the first blocking element 250 has a first receptacle 254 . The first receptacle 254 has a chamfered wall 256 facing the contact region 252 .

当第一容纳部254位于第一探入元件246上方时，第一探入元件246可以从相应的第一凹部248移出，并且探入到第一容纳部254中。When the first receiving portion 254 is located above the first penetrating element 246 , the first penetrating element 246 can move out of the corresponding first recess 248 and penetrate into the first receiving portion 254 .

在第二管48上形成贯通的凹部258。当第二探入元件246位于凹部258中和相应的第一凹部248中时，那么就阻止了第一管46与第二管48之间的纵向可移动性。当通过相应定位第一阻止元件250使第一容纳部254位于凹部258上方时，那么第一探入元件246可以完全从第一容纳部254移出，并且相应地释放第二管48相对第一管46的可运动性。A penetrating recess 258 is formed in the second pipe 48 . A longitudinal displaceability between the first tube 46 and the second tube 48 is then prevented when the second penetrating element 246 is located in the recess 258 and in the corresponding first recess 248 . When the first receptacle 254 is located above the recess 258 by correspondingly positioning the first blocking element 250, then the first penetrating element 246 can be completely moved out of the first receptacle 254 and correspondingly releases the second tube 48 relative to the first tube. 46 for mobility.

第一阻止元件250布置在引导部260上，并且以能沿平行于第二延伸轴线44的方向纵向移动的方式引导。The first blocking element 250 is arranged on the guide 260 and is guided longitudinally displaceably in a direction parallel to the second extension axis 44 .

在第一阻止元件250上布置有复位装置262，其尤其是通过一个或多个弹簧形成。复位装置定位在引导部260上。当第一阻止元件250如下这样地移动，即，使第一容纳部254位于凹部258上方时，则必须克服复位装置262的力。在没有外力作用到第一阻止元件250上时，该第一阻止元件复位，并且贴靠区域252遮盖凹部258，并且在此将第一探入元件246保持在第一容纳部254中，并且由此又阻止了第一管46相对第二管48的纵向可移动性。Arranged on the first blocking element 250 is a restoring device 262 , which is formed in particular by one or more springs. The reset device is positioned on the guide part 260 . If the first blocking element 250 is moved in such a way that the first receptacle 254 is located above the recess 258 , then the force of the reset device 262 must be overcome. When no external force acts on the first blocking element 250 , the first blocking element resets, and the abutment region 252 covers the recess 258 and holds the first penetrating element 246 in the first receptacle 254 and thereby This in turn prevents longitudinal displaceability of the first tube 46 relative to the second tube 48 .

第二锁定装置242具有第二探入元件246，其例如呈球形的或呈滚子形的。在第二管48上沿平行于第二延伸轴线44的方向间隔开地布置有第二凹部266。在第三管52上布置有贯通的凹部268。在锁定位置中，第二探入元件264被安置在第二凹部266和凹部268中，也就是说探入其中。The second locking device 242 has a second penetration element 246 which is spherical or roller-shaped, for example. Second recesses 266 are arranged at intervals on the second tube 48 in a direction parallel to the second extension axis 44 . A through recess 268 is arranged on the third tube 52 . In the locked position, the second protruding element 264 is seated in the second recess 266 and the recess 268 , that is to say penetrates into it.

第二锁定装置242此外还具有第二阻止元件270，其包括贴靠区域272。贴靠区域272原则上具有和第一阻止元件252的贴靠区域252相同的功能。第二阻止元件270相应地具有第二容纳部274。The second locking device 242 also has a second blocking element 270 which includes an abutment region 272 . The contact region 272 basically has the same function as the contact region 252 of the first blocking element 252 . The second blocking element 270 accordingly has a second receptacle 274 .

在第二锁定装置242的锁定位置中，第二探入元件246探入到相应的第二凹部266和凹部268中，并且贴靠区域272位于第二探入元件264上方并且使该定位稳固。In the locking position of the second locking device 242 , the second protruding element 246 protrudes into the corresponding second recess 266 and recess 268 , and the contact area 272 lies above the second probing element 264 and secures this positioning.

通过移动第二阻止元件270，第二容纳部274被带到第二探入元件264上方，也就是说凹部268上方，并且第二探入元件264可以移出并且在此探入到第二容纳部274中。由此取消了第二管48与第三管52之间的形状锁合，并且针对第二锁定装置242取消锁定位置。By moving the second blocking element 270 , the second receptacle 274 is brought above the second penetrating element 264 , that is to say above the recess 268 , and the second penetrating element 264 can be moved out and protruded into the second receptacle. 274 in. As a result, the positive fit between the second tube 48 and the third tube 52 is canceled and the locked position is canceled for the second locking device 242 .

第二阻止元件270在引导部276上以能纵向移动的方式引导。移动方向平行于第二延伸轴线44。The second blocking element 270 is guided longitudinally displaceably on a guide 276 . The direction of movement is parallel to the second extension axis 44 .

给第二阻止元件270配属了复位装置278，其尤其是通过弹簧形成。Assigned to the second blocking element 270 is a restoring device 278 , which is formed in particular by a spring.

为了第二阻止元件270的运动以便将第二容纳部274带到第二探入元件264上方，必须克服复位装置278的力。为此需要相应的外力。在没有外力的情况下，复位装置278提供第二阻止元件270的回移，以便将贴靠区域272带到第二探入元件264上方，并且将该第二探入元件挤压到相应的第二凹部266中。For the movement of the second blocking element 270 in order to bring the second receptacle 274 over the second penetrating element 264 , the force of the restoring device 278 must be overcome. Corresponding external forces are required for this. In the absence of an external force, the reset device 278 provides a return movement of the second blocking element 270 so as to bring the abutment region 272 above the second probing element 264 and press the second probing element to the corresponding first probing element. In the two recesses 266 .

在第二管48上布置有许多相应的第二容纳部274，以便能够实现第二管48相对第三管52的定位的相应的可变的调整和紧固。A number of corresponding second receptacles 274 are arranged on the second tube 48 in order to enable a corresponding variable adjustment and fastening of the positioning of the second tube 48 relative to the third tube 52 .

在吸尘器10的壳体12上布置有推动件280(例如图4)。该推动件280以能平行于第二延伸轴线44纵向移动的方式引导。该推动件280的上侧探伸超出第二壳体侧18，以便能够实现可操作性和尤其是能够实现按压可操作性。A pusher 280 (eg FIG. 4 ) is arranged on the housing 12 of the vacuum cleaner 10 . The pusher 280 is guided longitudinally displaceably parallel to the second extension axis 44 . The upper side of the pusher 280 protrudes beyond the second housing side 18 in order to enable operability and in particular push operability.

推动件280沿壳体器壁38延伸，并且在此沿第三管52延伸至第二阻止元件270。第二阻止元件270以力传递有效的方式与推动件280连接。该连接例如是牢固的。The pusher 280 extends along the housing wall 38 and here along the third tube 52 to the second blocking element 270 . The second blocking element 270 is connected to the pusher 280 in a force-transmittingly effective manner. This connection is, for example, firm.

在一种实施例中，第二阻止元件270大约被安置在风扇马达34的上方的区域的高度中。In one exemplary embodiment, the second blocking element 270 is arranged approximately at the height of the area above the fan motor 34 .

针对推动件280的纵向可移动性的相应的引导部设置在壳体器壁38上。Corresponding guides for the longitudinal displaceability of the pusher 280 are provided on the housing wall 38 .

原则上也可行的是，推动件280以能纵向移动的方式布置在管装置14上。In principle, it is also possible for the pusher 280 to be arranged longitudinally displaceable on the tube arrangement 14 .

第一阻止元件250与推动件280联接，但没有持久地与其连接。The first blocking element 250 is coupled to the pusher 280, but is not permanently connected thereto.

第二阻止元件270(图19)在贴靠区域252的延续部中具有端侧的端部282。利用该端侧的端部282，使第二阻止元件270可以作用到第一阻止元件250上，并且经由移动推动件280进而是第二阻止元件270，使第一阻止元件250可以原则上沿相同的方向移动，只要第二管48没有相对于第三管52移动。The second blocking element 270 ( FIG. 19 ) has an end-side end 282 in the continuation of the contact region 252 . With this end-side end 282 , the second blocking element 270 can act on the first blocking element 250 and, via the moving pusher 280 and thus the second blocking element 270 , the first blocking element 250 can in principle move along the same As long as the second tube 48 does not move relative to the third tube 52.

针对第一阻止元件250的引导部260牢固地与第二管48连接。针对第二阻止元件270的引导部276牢固地与第三管52连接。The guide 260 for the first blocking element 250 is firmly connected to the second tube 48 . The guide 276 for the second blocking element 270 is firmly connected to the third tube 52 .

第三锁定装置244包括第三探入元件284，其尤其是构造为滚子或球体。第三探入元件284在此参照沿第二延伸轴线44的方向地被定位在第一探入元件246与第二探入元件264之间。The third locking device 244 includes a third penetration element 284 , which is designed in particular as a roller or a ball. The third penetrating element 284 is positioned here between the first penetrating element 246 and the second penetrating element 264 with reference to the direction along the second extension axis 44 .

在第三管52上形成有针对第三探入元件284的容纳部286。与之相对应地，在第二管48上形成有针对第三探入元件284的容纳部288。在第三探入元件284被安置在容纳部286和容纳部288中时，则第三管52与第二管48之间建立起形状锁合的联接，并且由此使第二管46就其可运动性而言被紧固在第三管52上。即使是当第二锁定装置242没有被锁定，也就是说在解锁位置中时，当第三锁定装置244在其锁定位置中(在该锁定位置中，第三探入元件284被安置在容纳部286和容纳部288中)时，第二管48也不能够在第三管52中移动。A receptacle 286 for a third penetrating element 284 is formed on the third tube 52 . Correspondingly, a receptacle 288 for the third penetrating element 284 is formed on the second tube 48 . When the third penetrating element 284 is placed in the receptacle 286 and the receptacle 288, a form-locking connection is established between the third tube 52 and the second tube 48, and thus the second tube 46 is fixed to its Movably fastened to the third tube 52 . Even when the second locking device 242 is not locked, that is to say in the unlocked position, when the third locking device 244 is in its locked position (in this locked position, the third probing element 284 is placed in the receptacle 286 and accommodating portion 288 ), the second tube 48 cannot move in the third tube 52 either.

第二管48中的容纳部288朝第一管246敞开。第一管的器壁290在此阻止了可运动性，进而是阻止了第三探入元件284从容纳部286和288的可移出性。The receptacle 288 in the second tube 48 is open towards the first tube 246 . The wall 290 of the first tube here prevents the movement and thus the third penetrating element 284 from the receptacles 286 and 288 .

第一管46与远离吸嘴接口24的端部292相邻地具有针对第三探入元件284的凹部294(参见例如图20或图25)。该凹部294被安置在与第一凹部248不同的侧上。例如，凹部294和第一凹部248在直径上对置地布置。Adjacent to an end 292 remote from the nozzle connection 24 , the first tube 46 has a recess 294 for the third penetrating element 284 (see eg FIG. 20 or FIG. 25 ). This recess 294 is arranged on a different side than the first recess 248 . For example, the recess 294 and the first recess 248 are arranged diametrically opposite each other.

第一探入元件284例如与第二探入元件264在直径上对置地布置(其中，其能够定位在关于第二延伸轴线44不同的高度定位上)。The first penetrating element 284 is arranged, for example, diametrically opposite the second penetrating element 264 (wherein it can be positioned at different heights with respect to the second extension axis 44 ).

凹部294配属于第三探入元件284。第三锁定装置244的锁定位置当第三探入元件284没有探入到凹部294中时出现。The recess 294 is assigned to the third penetrating element 284 . The locked position of the third locking device 244 occurs when the third penetration element 284 does not penetrate into the recess 294 .

当第一管46相对第二管48位于特定的定位上，也就是说位于凹部294与第三探入元件284对置的定位中时，第三探入元件284可以从第三管52的容纳部286移出。由此取消了第二管48与第三管52之间的形状锁合，并且达到解锁位置，在解锁位置中，第三锁定装置244释放了第三管52在第二管48中的锁定。在第三锁定装置244的该解锁位置中，关于第二管48相对第三管52的定位的紧固，仅有第二锁定装置242起作用。When the first tube 46 is in a specific position relative to the second tube 48 , that is to say in the position where the recess 294 is opposite to the third penetrating element 284 , the third penetrating element 284 can be accommodated from the third tube 52 . Section 286 is removed. As a result, the positive lock between the second tube 48 and the third tube 52 is canceled and an unlocking position is reached in which the third locking device 244 releases the locking of the third tube 52 in the second tube 48 . In this unlocked position of the third locking means 244 only the second locking means 242 is active with regard to the securing of the positioning of the second tube 48 relative to the third tube 52 .

从第三锁定装置244的锁定位置到解锁位置的过渡通过第一管46相对第二管48的定位来确定，也就是当凹部294与第三探入元件284对置地定位，并且第三探入元件284探入到凹部294中时。在该定位中达到了第一管46相对第二管48的最大伸缩位置。The transition from the locked position to the unlocked position of the third locking device 244 is determined by the positioning of the first tube 46 relative to the second tube 48, that is, when the recess 294 is positioned opposite the third penetrating element 284, and the third penetrating When element 284 penetrates into recess 294 . In this positioning, the maximum telescopic position of the first tube 46 relative to the second tube 48 is reached.

凹部294在此如下这样地布置，即，只有当第一锁定装置240位于锁定位置中时，第三探入元件284才可以探入。凹部294与相应的最高的第一凹部248(在图25中用248b标记)之间的高度间距相应于第一探入元件246与第三探入元件284之间的间距。The recess 294 is arranged here in such a way that the third insertion element 284 can only be inserted when the first locking device 240 is in the locking position. The height spacing between the recesses 294 and the respective highest first recess 248 (designated 248 b in FIG. 25 ) corresponds to the spacing between the first penetrating element 246 and the third penetrating element 284 .

沿第二延伸轴线44的在第一探入元件246与第三探入元件284之间的相对高度间距与第一管46相对第三管52的或第二管48相对第三管52的定位无关地保持恒定；当第三探入元件284从第三管52的容纳部286移出并且探入凹部294中时，其通过第二管48相对第三管52的运动与第二管48同步。因为引导部260牢固地布置在第二管48上并且第三探入元件284沿平行于第二延伸轴线44的方向相对于第二管48是牢固的，所以实现了所描述的同步。The relative height spacing between the first penetrating element 246 and the third penetrating element 284 along the second extension axis 44 and the positioning of the first tube 46 relative to the third tube 52 or the second tube 48 relative to the third tube 52 irrespectively remains constant; when the third penetrating element 284 is moved out of the receptacle 286 of the third tube 52 and penetrates into the recess 294 , it is synchronized with the second tube 48 by the movement of the second tube 48 relative to the third tube 52 . The described synchronization is achieved because the guide 260 is firmly arranged on the second tube 48 and the third penetrating element 284 is fixed relative to the second tube 48 in a direction parallel to the second extension axis 44 .

替选地可行的是，从第三解锁装置244的锁定位置到解锁位置的过渡是受力控制的。Alternatively, it is possible for the transition from the locked position to the unlocked position of the third unlocking device 244 to be force-controlled.

在同样在图19中以虚线作为替选方案示出的实施例中，没有设置相应于第三探入元件284的探入元件。In the exemplary embodiment, also shown as an alternative in dashed lines in FIG. 19 , no penetrating element corresponding to the third penetrating element 284 is provided.

力加载(代替经由探入元件实现的形状锁合的连接地)提供了第三管52与第二管48之间的力锁合的联接，用以相应地紧固相对定位。当例如通过相应定位第一管46于是使加载力不再存在有力锁合的联接时，则达到解锁位置。The force application (instead of a form-locking connection via the penetration element) provides a force-locking coupling between the third tube 52 and the second tube 48 for correspondingly securing the relative positioning. The unlocked position is reached when, for example by correspondingly positioning the first tube 46 , the force-locking coupling is no longer present due to the loading force.

为了进行力加载，设置了力加载元件296，例如被弹簧加载的杠杆元件。For force application, a force application element 296 is provided, for example a spring-loaded lever element.

在第三锁定装置244的解锁位置中(在其中，第二管48和第一管46一起通过第一锁定装置240锁定)，由第二管48和第一管46构成的组合能作为整体相对于第三管52移动。由此，第一阻止元件250与第二阻止元件270脱联，并且松开了第一阻止元件在端侧的端部282上的接触，并且因此松开了推动件280。推动件280不再作用到第一锁定装置240上。In the unlocked position of the third locking device 244 (in which the second tube 48 and the first tube 46 are locked together by the first locking device 240), the combination of the second tube 48 and the first tube 46 can be opposed as a whole. Move on the third tube 52. As a result, the first blocking element 250 is decoupled from the second blocking element 270 and the contact of the first blocking element at the end-side end 282 and thus the pusher 280 is released. The pusher 280 no longer acts on the first locking device 240 .

管装置14利用锁定装置240、242、244如下这样工作：The tube arrangement 14 works with the locking devices 240, 242, 244 as follows:

在吸尘器10的站立位置22下(参见图1至4)，第二管48完全地在其运动行程内完全探入到第三管52中。第一管46在其运动行程内完全探入到第二管48中。第二管48相对于第三管52的定位通过第二锁定装置242和第三锁定装置244紧固。In the standing position 22 of the vacuum cleaner 10 (cf. FIGS. 1 to 4 ), the second tube 48 projects completely into the third tube 52 throughout its travel path. The first tube 46 penetrates completely into the second tube 48 over the course of its movement. The positioning of the second tube 48 relative to the third tube 52 is secured by the second locking means 242 and the third locking means 244 .

吸嘴接口24如下程度地探伸超出第一壳体侧16，即，使得能够固定地面吸嘴76，并且在站立位置下，能够使第一固定装置92作用在第二固定装置94上。The nozzle connection 24 protrudes beyond the first housing side 16 to the extent that the floor nozzle 76 can be fixed and, in the standing position, the first fastening device 92 can act on the second fastening device 94 .

管装置14的长度为了抽吸运行相对于站立位置22得到提高。The length of the tube arrangement 14 is increased relative to the standing position 22 for suction operation.

为此，第一管46首先从第二管48移出。To this end, the first tube 46 is first removed from the second tube 48 .

为此，推动件280被操纵并且向下移动，也就是说朝吸嘴接口24的方向移动。推动件在此移动第二阻止元件270并且经由端侧的端部282的止挡也移动第一阻止元件250。当第一容纳部254位于凹部258上方时，第一探入元件246移出，其中于是，取消了第一管46与第二管48之间的形状锁合，并且第一管46能相对于第二管48移动。To this end, the pusher 280 is actuated and moved downwards, that is to say in the direction of the nozzle connection 24 . The pusher here displaces the second blocking element 270 and, via the end stop 282 at the end, also the first blocking element 250 . When the first receptacle 254 is located above the recess 258, the first penetrating element 246 is moved out, wherein then the form-fit between the first tube 46 and the second tube 48 is canceled and the first tube 46 can be moved relative to the first tube 46. Two pipes 48 move.

相应的移动定位通过结束作用到推动件280上的力，在探入元件246没有相应探入到凹部248中的情况下并且根据期望的纵向定位和经由贴靠区域252的保持来锁定。The corresponding displacement positioning is locked by ending the force acting on the pusher 280 without corresponding penetration of the penetration element 246 into the recess 248 and according to the desired longitudinal positioning and retention via the contact region 252 .

在操纵推动件280时，第二锁定装置242也与第一锁定装置240同时锁定。然而基于第三锁定装置244，使第二管48保持紧固在第三管52上，只要第三探入元件248没有探入到凹部294中。When the pushing member 280 is manipulated, the second locking device 242 is also locked simultaneously with the first locking device 240 . Due to the third locking device 244 , however, the second tube 48 remains fastened to the third tube 52 as long as the third probing element 248 does not penetrate into the recess 294 .

在图15(a)、15(b)和16中示出了第一管46相对第二管48的不同的定位，其中，第二管48经由第三锁定装置244紧固在第三管52上。Different positioning of the first tube 46 relative to the second tube 48 is shown in FIGS. superior.

第一管46相对第二管48的在图15(a)、15(b)中指示的定位是具有锁定位置的定位。根据图15(a)的定位相应于针对手持式抽吸器运行的定位。根据图15(b)的定位相应于针对矮的操作人员的针对地面抽吸器运行的定位。The positioning indicated in Figures 15(a), 15(b) of the first tube 46 relative to the second tube 48 is a positioning with a locked position. The positioning according to FIG. 15( a ) corresponds to the positioning for the operation of the hand-held aspirator. The positioning according to FIG. 15( b ) corresponds to the positioning for floor suction operation for short operators.

吸嘴接口24进而还有抽吸吸嘴相对于第一壳体侧16的定位因此能在预定的路程内调整。The positioning of the nozzle interface 24 and thus also the suction nozzle relative to the first housing side 16 can thus be adjusted within a predetermined path.

在图20中示出了针对第一锁定装置240的、第二锁定装置242的和第三锁定装置244的锁定位置，该锁定位置相应于站立位置22，也就是说在其中，管装置14具有最小长度。FIG. 20 shows a locked position for the first locking device 240 , the second locking device 242 and the third locking device 244 , which corresponds to the standing position 22 , that is to say in which the tube device 14 has Minimum length.

在图21中示出了管装置14的相应于根据图16的位置的位置。FIG. 21 shows the position of the pipe arrangement 14 corresponding to the position according to FIG. 16 .

当第一管46如下程度地从第二管48拉出，即，使第三探入元件284可以在端部292的区域中侵入到凹部294中时，也达到了第一锁定装置240的锁定位置。第三锁定装置244现在位于解锁位置中，并且原则上，第二管48相对于第三管52是能纵向移动的，并且第二锁定装置242现在确定了第二管48相对第三管52的可移动性，并且通过调整第二锁定装置242的相应的锁定位置紧固移动位置。在图17、18和22中示出了针对第二管48相对于第三管52的被锁定的位置的相应的不同的定位。Locking of the first locking device 240 is also achieved when the first tube 46 is pulled out of the second tube 48 to such an extent that the third penetrating element 284 can penetrate into the recess 294 in the region of the end 292 . Location. The third locking device 244 is now in the unlocked position and, in principle, the second tube 48 is longitudinally movable relative to the third tube 52, and the second locking device 242 now determines the position of the second tube 48 relative to the third tube 52. Movability, and fasten the moving position by adjusting the corresponding locking position of the second locking device 242. The corresponding different positioning for the locked position of the second tube 48 relative to the third tube 52 is shown in FIGS. 17 , 18 and 22 .

当第二管48相对第三管52从第三锁定装置244被锁定的基本位置起移动时，第一阻止元件250与推动件280进而与第二阻止元件270脱联。为此参见例如图22。第一阻止元件250与第二阻止元件270间隔开。When the second tube 48 moves relative to the third tube 52 from the locked basic position of the third locking device 244 , the first blocking element 250 is disconnected from the pusher 280 and thus from the second blocking element 270 . See, for example, FIG. 22 for this. The first blocking element 250 is spaced apart from the second blocking element 270 .

当从拉出的位置起，第二管48又通过锁定第二锁定装置242在其相应的行程内移回到第三管52中时，则当第一阻止元件250止挡到第二阻止元件270的端侧的端部282上时达到最终位置。然后通过操纵推动件280可以达到第一锁定装置240的锁定位置，并且第三探入元件284可以探入到容纳部286中。由此，第二管48又紧固在第三管52上，并且第一管46可以在第二管48中移动。于是又可以达到站立位置22。When from the pulled out position, the second tube 48 moves back into the third tube 52 in its corresponding stroke by locking the second locking device 242, then when the first blocking element 250 stops against the second blocking element The final position is reached when the end-side end 282 of 270 is on. The locking position of the first locking device 240 can then be reached by actuating the pusher 280 and the third insertion element 284 can be inserted into the receptacle 286 . As a result, the second tube 48 is again fastened to the third tube 52 and the first tube 46 can move in the second tube 48 . The standing position 22 can then be reached again.

通过根据本发明的管装置，可以经由(至少是)三个管元件46、48、52在大的长度范围内调整管装置14的长度。在此仅需要设置一个操作元件，即推动件280。由此得到高的操作舒适性。With the tube arrangement according to the invention, the length of the tube arrangement 14 can be adjusted over a large length range via (at least) the three tube elements 46 , 48 , 52 . Only one operating element, the pusher 280 , needs to be provided here. This results in high operating comfort.

推动件280的定位从站立位置22起确定第二锁定装置242(和第一锁定装置240)是否位于锁定位置中。当第一锁定装置240没有位于锁定位置中时，第一管46可以相对于第二管48运动。第二管48相对于第三管52的可移动性通过第一管46相对第二管48的定位预定，而不必设置附加的操作元件。The positioning of the pusher 280 determines from the standing position 22 whether the second locking device 242 (and the first locking device 240 ) is in the locked position. When the first locking device 240 is not in the locked position, the first tube 46 is movable relative to the second tube 48 . The movability of the second tube 48 relative to the third tube 52 is predetermined by the positioning of the first tube 46 relative to the second tube 48 without having to provide additional operating elements.

管装置14的长度调整具有很高的操作舒适性。The length adjustment of the tube arrangement 14 provides a high operating comfort.

原则上，根据本发明的解决方案也可以应用到具有多于三个管的管装置上。具有三个管46、48、52和相应的锁定装置240、242、244的管装置在一定程度上形成用于具有多于三个管的结构的基本单元。In principle, the solution according to the invention can also be applied to tube arrangements with more than three tubes. A tube arrangement with three tubes 46, 48, 52 and corresponding locking means 240, 242, 244 forms to some extent a basic unit for structures with more than three tubes.

根据本发明提供了具有广泛的使用功能的吸尘器10。According to the present invention there is provided a vacuum cleaner 10 having a wide range of usage functions.

该吸尘器通过如下方式可以用作地面吸尘器，即，地面吸嘴26通过移动吸嘴接口24离开站立位置22。The vacuum cleaner can be used as a floor vacuum cleaner in that the floor nozzle 26 is moved out of the standing position 22 by moving the nozzle connection 24 .

可以调整出对于用户来说最佳的定位。用户可以在连接管58的弓形把手60上握住吸尘器10并且执行抽吸运动。The best positioning for the user can be adjusted. The user can hold the vacuum cleaner 10 on the bow-shaped handle 60 of the connection tube 58 and perform a suction movement.

吸尘器10可以在站立位置22中节省空间地保管。The vacuum cleaner 10 can be stored in a space-saving manner in the standing position 22 .

吸尘器10也可以用作手持式抽吸器，其是可自由握持的并且例如不支撑在地面上。地面吸嘴26于是通过相应的抽吸吸嘴代替。所需的长度可以经由管装置14借助操作推动件280来以简单的方式调整。The vacuum cleaner 10 can also be used as a hand-held vacuum cleaner, which is free to hold and is not supported, for example, on the ground. The floor suction nozzle 26 is then replaced by a corresponding suction nozzle. The desired length can be adjusted in a simple manner via the tube arrangement 14 by means of the actuating pusher 280 .

可以实现具有直立功能的“立式抽吸器”，但其中，吸尘器也可以用作手持式抽吸器。An "upright extractor" with upright function is possible, but in which the vacuum cleaner can also be used as a hand-held extractor.

吸尘器10可以以紧凑的、节省空间的方式实现。其可以以相对小的质量构造并且可以快速使用。吸尘器可以根据用户的愿望基于直立功能在站立位置22下节省空间地停放，而不需要用于倚靠的壁或类似物。The vacuum cleaner 10 can be realized in a compact, space-saving manner. It can be constructed with relatively low mass and can be used quickly. Depending on the user's wishes, the vacuum cleaner can be parked in a space-saving manner in the standing position 22 due to the upright function, without requiring a wall or the like to lean on.
