用于真空吸尘器的马达、风扇和过滤器装置Motor, fan and filter units for vacuum cleaners

技术领域technical field

本发明涉及一种用于真空吸尘器的马达、风扇和过滤器装置以及包括这种马达、风扇和过滤器装置的真空吸尘器。The present invention relates to a motor, fan and filter arrangement for a vacuum cleaner and a vacuum cleaner comprising such a motor, fan and filter arrangement.

背景技术Background technique

众所周知真空吸尘器主要用于收集尘垢，尽管能够收集液体的干湿变型(wet-and-dry variant)也是已知的。通常，真空吸尘器用于家庭环境中，尽管真空吸尘器也可用于诸如工地的其它环境中。通常，它们是电动的，因此包括电动机和连接到电动机输出轴的风扇、用于污浊空气的入口、用于洁净空气的出口以及用于灰尘、污垢并且也可能液体的集尘室。可以通过主线电源为马达提供电功率，在这种情况下，真空吸尘器将进一步包括可通过可拆卸和可替换的电池组或者通过一个或多个内装式的可充电电池提供的电力电缆，在这种情况下，该真空吸尘器将进一步包括一些诸如插头的装置，用于将真空吸尘器连接到再充电单元。当从这些源之一为真空吸尘器提供电功率时，电动机驱动风扇以沿气流路径吸入污浊空气通过污浊空气入口，然后经由集尘室到达洁净空气出口。Vacuum cleaners are known primarily for collecting dirt, although wet-and-dry variants capable of collecting liquids are also known. Typically, vacuum cleaners are used in domestic environments, although vacuum cleaners may also be used in other environments such as construction sites. Usually, they are electric and thus comprise an electric motor and a fan connected to the output shaft of the motor, an inlet for dirty air, an outlet for clean air and a collection chamber for dust, dirt and possibly also liquids. Electric power to the motor may be provided by a mains power supply, in which case the vacuum cleaner will further comprise a power cable which may be provided by a removable and replaceable battery pack or by one or more built-in rechargeable batteries, in which case In some cases, the vacuum cleaner will further comprise some means, such as a plug, for connecting the vacuum cleaner to the recharging unit. When the vacuum cleaner is supplied with electrical power from one of these sources, the motor drives the fan to draw dirty air along the airflow path through the dirty air inlet and then through the dust chamber to the clean air outlet.

还将某一装置设置在沿着气流通道的某点处，所述装置用于分离出污浊空气中所夹带的尘垢(以及也可能的液体)并将这些尘垢沉淀在集尘室中。这种分离装置可包括一个或多个过滤器和/或气旋分离设备。传统地，如果分离装置包括过滤器，则马达、风扇和过滤器具有如图1中示意性表示的装置。从图1中可以看出，已经经由污浊空气入口进入真空吸尘器的污浊空气通过过滤器30从区域P流动到区域Q。这将污浊空气中所夹带的尘垢(以及也可能的液体)分离出来，因此已过滤材料保留在区域P中。如果像通常那样将过滤器30本身设置在收集室内，则保留在区域P中的已过滤材料就积聚在那里。然后洁净空气从过滤器30另一侧的区域Q通过形成在壁40中的格栅42流动到第三区域R，其中过滤器30安装在壁40上。虽然可设置附加的过滤器，但是格栅42通常不具有过滤效果。相反它的主要目的是防止使用者接近安装在马达10的马达输出轴12上的风扇20，当通过电端子14、16为马达10提供电力时，马达10通过真空吸尘器吸入空气。如图1所示，风扇20是一叶轮，其轴向向其叶面吸入空气并切向排出空气，然后空气从此处流动到真空吸尘器的洁净空气出口。具有图1的传统马达、风扇和过滤器的可手持真空吸尘器的实例也以本申请人的名义在欧洲专利公开No.EP 1 523 916 A中进行了说明。Also provided at some point along the air flow path is a device for separating out entrained dirt (and possibly also liquid) in the dirty air and depositing this dirt in the dust chamber. Such separation means may include one or more filters and/or cyclonic separation devices. Traditionally, if the separation device includes a filter, the motor, fan and filter have an arrangement as schematically represented in FIG. 1 . As can be seen in FIG. 1 , the dirty air that has entered the vacuum cleaner via the dirty air inlet flows from zone P to zone Q through thefilter 30 . This separates the dirt (and possibly also liquid) entrained in the dirty air, so that the filtered material remains in zone P. If thefilter 30 itself is arranged in the collection chamber as usual, the filtered material remaining in the area P accumulates there. The clean air then flows from the region Q on the other side of thefilter 30 to the third region R through thegrill 42 formed in thewall 40 on which thefilter 30 is installed. Thegrille 42 generally has no filtering effect, although additional filters may be provided. Rather its main purpose is to prevent the user from accessing thefan 20 mounted on themotor output shaft 12 of themotor 10 which draws air through the vacuum cleaner when themotor 10 is powered via theelectrical terminals 14,16. As shown in FIG. 1, thefan 20 is an impeller which sucks air axially towards its blade surface and discharges air tangentially, from where the air flows to the clean air outlet of the vacuum cleaner. An example of a hand-held vacuum cleaner with the conventional motor, fan and filter of Figure 1 is also described in European Patent Publication No. EP 1 523 916 A in the name of the applicant.

因此上述的马达、风扇和过滤器的传统装置形成了三个分隔区域P、Q和R，其中第二区域，区域Q实际上是″死″空间。换句话说，区域P可用于为所述的过滤材料提供集尘室，而区域R容纳马达10和风扇20，区域Q仅占用空间而不实现任何目的。在一方面，过滤器30应具有尽可能大的表面面积以提高它的过滤效果，这往往会增加区域Q的尺寸。这恰恰是为什么通常避免在格栅42的位置横过风扇20的表面设置平坦过滤器的原因。尽管这可将区域Q完全省去，但是由于在气流路径中形成瓶颈，这种小的过滤器也会严重地降低真空吸尘器的效率。此外，为了进一步提高过滤器30的效率，经常将过滤器设置成圆柱形或截头圆锥形形状。这种形状促使区域P中的污浊空气在通过过滤器30之前绕过滤器30旋动，这具有在旋风分离器中的离心力作用下背离过滤器30向外掷出尘垢颗粒的效果。另一方面，然而，如果必须为过滤器30提供较大的表面面积或这样的形状，那么为了节省空间并减小区域Q尺寸，将风扇20和可能的同样部件或整个马达10插入到区域Q中的可选方案也是不可预期的，因为这将会妨碍从风扇20切向排出的空气流出到真空吸尘器的洁净空气出口，而是使得由风扇排出的空气撞击过滤器30的内表面，从而与通过过滤器30流入的洁净空气相对，并再次严重地降低过滤操作的效率。The conventional arrangement of motors, fans and filters described above thus creates three compartmentalized regions P, Q and R, of which the second region, region Q, is effectively a "dead" space. In other words, zone P can be used to provide a dust chamber for said filter material, while zone R accommodatesmotor 10 andfan 20 and zone Q merely takes up space without fulfilling any purpose. On the one hand, thefilter 30 should have as large a surface area as possible to enhance its filtering effect, which tends to increase the size of the area Q. This is precisely why placing a flat filter across the face of thefan 20 at the location of thegrille 42 is generally avoided. Although this would eliminate area Q entirely, such a small filter would also seriously reduce the efficiency of the vacuum cleaner by creating a bottleneck in the airflow path. Furthermore, to further increase the efficiency of thefilter 30, the filter is often provided in a cylindrical or frusto-conical shape. This shape encourages the dirty air in region P to swirl around thefilter 30 before passing through it, which has the effect of throwing dirt particles outwards away from thefilter 30 under the centrifugal force in the cyclone. On the other hand, however, if it is necessary to provide thefilter 30 with a larger surface area or such a shape, then in order to save space and reduce the size of the area Q, thefan 20 and possibly the same part or theentire motor 10 is inserted into the area Q The alternative in 20 is also not contemplated, as this would prevent the air discharged tangentially from thefan 20 from flowing out to the clean air outlet of the vacuum cleaner, but instead cause the air discharged by the fan to hit the inner surface of thefilter 30, thereby interacting with The influx of clean air through thefilter 30 is counterproductive and again severely reduces the efficiency of the filtering operation.

因此图1中示出的马达、风扇和过滤器的传统装置在其空间的使用方面是低效的，但是却没有明显的能够解决其本身存在的这个问题的解决方法。在紧凑型或手持真空吸尘器中，这种低效的空间使用是特别不合需要的，而在这种类型的真空吸尘器中，空间的有效使用是相当重要的，任何浪费的空间都将必然增加所述真空吸尘器的整体重量，而不会带来任何与其相当的益处。The conventional arrangement of motors, fans and filters shown in Figure 1 is therefore inefficient in its use of space, but has no apparent solution to this problem inherent in it. This inefficient use of space is particularly undesirable in compact or hand-held vacuum cleaners, where efficient use of space is of considerable importance, and any wasted space will necessarily add to the the overall weight of the vacuum cleaner described above without any commensurate benefits.

发明内容Contents of the invention

因此本发明的目的是提供一种用于真空吸尘器的马达、风扇和过滤器装置，该装置能够比图1中所示的传统装置更好地利用空间。本发明的另一目的是提供一种特别适合用于紧凑型或手持真空吸尘器中的马达、风扇和过滤器装置。本发明的又一目的是提供一种包括这种马达、风扇和过滤器装置的真空吸尘器。It is therefore an object of the present invention to provide a motor, fan and filter arrangement for a vacuum cleaner which makes better use of space than the conventional arrangement shown in FIG. 1 . Another object of the present invention is to provide a motor, fan and filter arrangement particularly suitable for use in compact or hand-held vacuum cleaners. Yet another object of the present invention is to provide a vacuum cleaner comprising such a motor, fan and filter arrangement.

因此，在第一方面，本发明提供一种用于真空吸尘器的马达、风扇和过滤器装置，该装置包括：马达；风扇，该风扇连接到马达的输出轴并具有轴向空气入口；以及过滤器；其中，将风扇设置为使其轴向入口面对马达；并且马达被容纳在过滤器中。这种装置使得能够沿与传统装置相反的方向将所述马达设置在过滤器中，从而使得来自过滤器的洁净空气在遭遇风扇之前被吸入马达。因此通过在马达输出轴上从马达的输出轴伸出，仍可将风扇设置在过滤器外部，使得由风扇排出的空气不会受到过滤器的阻碍，并且仍可容易地流向真空吸尘器的洁净空气出口。此外，由于在来自过滤器的洁净空气遭遇风扇之前被吸入马达，所以还提供了利用来自过滤器的空气冷却马达的有益副作用，而不像图1的传统装置那样，在图1的传统装置中如果通过由风扇排出的空气对马达进行了冷却，那么空气从风扇的流出将不得不改变路线以越过马达。这将需要气流改变方向，从而将空气动力学阻力引入到气流中并降低了真空吸尘器的整体效率。与此相反，本发明的马达、风扇和过滤器装置不需要使由风扇排出的空气改变线路，并且由于马达容纳在过滤器中，所以实现了空间的有效使用，并且因此特别适合用于紧凑型或手持真空吸尘器中。Thus, in a first aspect, the present invention provides a motor, fan and filter arrangement for a vacuum cleaner comprising: a motor; a fan connected to an output shaft of the motor and having an axial air inlet; and a filter wherein the fan is arranged such that its axial inlet faces the motor; and the motor is housed in the filter. This arrangement makes it possible to place the motor in the filter in the opposite direction to conventional arrangements, so that clean air from the filter is sucked into the motor before encountering the fan. So by sticking out from the output shaft of the motor on the motor output shaft it is still possible to place the fan outside the filter so that the air expelled by the fan is not obstructed by the filter and can still flow easily to the clean air of the vacuum cleaner exit. Furthermore, since clean air from the filter is drawn into the motor before it encounters the fan, it also provides the beneficial side effect of cooling the motor with air from the filter, unlike the conventional arrangement of Figure 1, where If the motor is cooled by the air expelled by the fan, the outflow of air from the fan will have to be re-routed past the motor. This would require the airflow to change direction, introducing aerodynamic drag into the airflow and reducing the overall efficiency of the vacuum cleaner. On the contrary, the motor, fan and filter device of the present invention does not need to change the route of the air exhausted by the fan, and since the motor is housed in the filter, efficient use of space is realized, and thus it is particularly suitable for use in compact or in a handheld vacuum cleaner.

本发明的马达、风扇和过滤器装置还具有明显的优点：鉴于图1的传统装置中的风扇是切向排出空气的叶轮，而在本发明的马达、风扇和过滤器装置中的风扇可以是叶轮或螺旋桨，后者从与通过风扇将空气轴向吸入的表面相对的一侧轴向排出空气。这是因为在传统装置中，风扇的背面受到马达的阻碍，因此从风扇流出的空气必须切向引出，而在本发明的马达、风扇和过滤器装置中，风扇的背面是不受遮挡的，使得来自风扇的空气既能够如在叶轮中那样切向排出又能如在螺旋桨中那样轴向排出。这为包括这种马达、风扇和过滤器装置的真空吸尘器中的气流的总体设计提供了极大的多功能性，从而能够自由地引导由风扇排出的空气。The motor, fan and filter device of the present invention also has obvious advantages: Whereas the fan in the conventional device of Fig. 1 is an impeller that discharges air tangentially, the fan in the motor, fan and filter device of the present invention can be The impeller or propeller that axially discharges air from the side opposite the surface from which it is drawn axially by the fan. This is because in conventional arrangements the back of the fan is obstructed by the motor, so the air flowing from the fan has to be drawn tangentially, whereas in the motor, fan and filter arrangement of the present invention, the back of the fan is unobstructed, This allows the air from the fan to exit both tangentially as in the impeller and axially as in the propeller. This provides great versatility to the overall design of the airflow in a vacuum cleaner comprising such a motor, fan and filter arrangement, so that the air expelled by the fan can be freely directed.

本发明的马达、风扇和过滤器装置还可包括设置在马达和过滤器之间的可透气壳体。因此，如果例如为了清洗或替换它过滤器是可拆卸的，则壳体可防止使用者接近马达和风扇，但是空气仍然能够通过壳体从过滤器到达风扇。可选地马达壳体可以是不透气的，在这种情况下，装置还可包括设置在马达和风扇之间的格栅，马达输出轴穿过该格栅。因此，不透气的壳体完全防止使用者接近马达的电部件，但是空气仍可通过格栅从过滤器到达风扇。对于使用者来说，这种可选方案比可透气的马达壳体更安全，但也具有相应的缺点，即不能通过来自过滤器的空气对马达进行冷却。The motor, fan and filter assembly of the present invention may also include a gas permeable housing disposed between the motor and the filter. Thus, if the filter is removable, for example for cleaning or replacing it, the housing can prevent the user from accessing the motor and fan, but air can still pass through the housing from the filter to the fan. Alternatively the motor housing may be airtight, in which case the device may also include a grill disposed between the motor and the fan through which the motor output shaft passes. Thus, the airtight housing completely prevents the user from accessing the electrical components of the motor, but air can still pass through the grill from the filter to the fan. This alternative is safer for the user than a breathable motor housing, but has the corresponding disadvantage that the motor cannot be cooled by air from the filter.

优选地，马达的输出轴从过滤器内部延伸，并且输出轴的一端被安装在轴承上，该轴承设置在与马达相反的风扇侧上。这样，通向风扇的轴向入口不会受到马达或轴承的阻挡，这改进了进入风扇的气流的空气动力学效率，而延长的马达输出轴通过轴承支承，当风扇旋转时，这可防止延长的马达输出轴由于风扇中的任何潜在不平衡而振动。Preferably, the output shaft of the motor extends from inside the filter and one end of the output shaft is mounted on a bearing provided on the fan side opposite the motor. This way, the axial inlet to the fan is not blocked by the motor or bearings, which improves the aerodynamic efficiency of the airflow into the fan, while the extended motor output shaft is supported by bearings, which prevents elongation when the fan rotates. The motor output shaft vibrates due to any potential imbalance in the fan.

在第二方面，本发明还提供了一种根据本发明第一方面的包括马达、风扇和过滤器装置的真空吸尘器。优选地，该真空吸尘器是手持真空吸尘器，该手持真空吸尘器能够最大化地利用这种马达、风扇和过滤器装置所提供的节省空间。In a second aspect, the invention also provides a vacuum cleaner comprising a motor, a fan and a filter arrangement according to the first aspect of the invention. Preferably, the vacuum cleaner is a hand-held vacuum cleaner capable of maximizing the space savings provided by such a motor, fan and filter arrangement.

具体实施方式Detailed ways

首先参照图2A至图2D，这些附图示出了根据本发明实施例适合用于马达、风扇和过滤器装置中的马达和风扇。马达10具有输出轴12，风扇20安装在该输出轴12上。通过电触头14、16向马达10提供电功率，使得在马达的运行期间，空气沿图2A中所示的箭头方向轴向地越过马达10进入风扇20的进气口或“风眼”24，风扇20是一叶轮，因此其可切向地排出空气。远离马达10的输出轴12的末端被安装在支承输出轴12的轴承22上，当输出轴12旋转时，轴承22能够防止输出轴12由于风扇20中的任何潜在的不平衡而振动。从图2B的俯视图可以最好地看出，马达输出轴12具有足够大的长度以允许马达10周围的空气不受阻碍地自由流动到进气口24中，并且还可从图2C的端部视图看出，风扇20的轴向进气口24具有比马达10更大的直径，使得进气口24的圆周部分呈现完全不受马达10的阻碍。图2B也通过标记为“X”的箭头指示了适合用于真空吸尘器中的传统马达和风扇装置中的马达输出轴的通常长度。在这种传统装置中，通常不需要轴承22，因为马达输出轴的长度越短使得该轴越坚硬，因此当输出轴旋转时，输出轴较少受到由风扇中的任何潜在不平衡所引起的振动的影响。然而，通过将延伸件(extension piece)附加到传统的马达的较短的马达输出轴和/或将联轴器附加到承载风扇的另一轴上，传统的马达也可以适用于根据本发明的马达、风扇、过滤器装置中。图2B中标记为“X”的箭头还指示了可设置在马达10和风扇20之间的格栅(图中未示)的大概位置，马达的输出轴12可穿过该格栅，从而将风扇20遮蔽防止使用者接近。该格栅可用于为马达输出轴提供附加支承。Reference is first made to FIGS. 2A-2D which illustrate a motor and fan suitable for use in a motor, fan and filter arrangement according to an embodiment of the present invention. Themotor 10 has anoutput shaft 12 on which afan 20 is mounted. Electrical power is supplied to themotor 10 through theelectrical contacts 14, 16 so that during operation of the motor, air passes axially over themotor 10 in the direction of the arrow shown in FIG. Thefan 20 is an impeller so it discharges air tangentially. The end of theoutput shaft 12 remote from themotor 10 is mounted on abearing 22 supporting theoutput shaft 12 which prevents theoutput shaft 12 from vibrating due to any potential imbalance in thefan 20 as theoutput shaft 12 rotates. As best seen from the top view of Figure 2B, themotor output shaft 12 is of sufficient length to allow the air surrounding themotor 10 to flow unhindered freely into theair inlet 24, and is also accessible from the end of Figure 2C. It can be seen that theaxial inlet 24 of thefan 20 has a larger diameter than themotor 10 , so that the circumferential portion of theinlet 24 appears completely unobstructed by themotor 10 . Figure 2B also indicates the typical length of a motor output shaft suitable for use in a conventional motor and fan arrangement in a vacuum cleaner by the arrow marked "X". In such conventional arrangements, thebearing 22 is generally not required because the shorter length of the motor output shaft makes the shaft stiffer and therefore less susceptible to any potential imbalances in the fan as it rotates. The effect of vibration. However, by attaching an extension piece to the shorter motor output shaft of the conventional motor and/or attaching a coupling to the other shaft carrying the fan, conventional motors can also be adapted for use in the motor according to the invention. Motor, fan, filter unit. The arrow marked "X" in FIG. 2B also indicates the approximate location of a grille (not shown) that may be provided between themotor 10 and thefan 20 through which theoutput shaft 12 of the motor may pass, thereby Thefan 20 is shielded from access by the user. This grid can be used to provide additional support for the motor output shaft.

接下来转到图3，示出了根据本发明的包括马达、风扇和过滤器装置的真空吸尘器的第一实施例。这是一种紧凑的杆形真空吸尘器(或“立式真空吸尘器”)，在先前共同审理中的欧洲专利申请No.EP07102186.9中进行了更详细的说明，本申请要求该欧洲专利申请的优先权。真空吸尘器100包括上体部50、下体部60、地板端70、手柄80和灰尘过滤部90。上体部50可相对于下体部60绕灰尘过滤部90的轴线转动。地板端70包括污浊空气入口和一对地板引轮(f1oor-running wheel)71、72，而手柄80包括电接通/断开开关81。灰尘过滤部90包括切向入口管道91、集尘室、洁净空气出口以及根据本发明的马达、风扇和过滤器装置，下面参照图4至图6对其进行更详细地描述。在真空吸尘器100的运行期间，使用者通过操作电接通/断开开关81启动容纳在灰尘过滤部90中的马达，所述开关81经由在上体部50内部穿过的电线连接到马达。这使得污浊空气从地板端70的污浊空气入口向上流入位于下体部60内的管道到达切向入口管道91，从那里污浊空气进入灰尘过滤部90的集尘室。Turning next to Figure 3, a first embodiment of a vacuum cleaner comprising a motor, fan and filter arrangement according to the present invention is shown. This is a compact stick vacuum cleaner (or "upright vacuum cleaner"), described in more detail in previously co-pending European Patent Application No. EP07102186.9, the application claims the priority.

Thefloor end 70 includes a dirty air inlet and a pair of floor-runningwheels 71 , 72 , while thehandle 80 includes an electrical on/offswitch 81 . Thedust filter section 90 comprises atangential inlet duct 91 , a dust collection chamber, a clean air outlet and a motor, fan and filter arrangement according to the invention, which are described in more detail below with reference to FIGS. 4 to 6 . During operation of thevacuum cleaner 100 , the user activates the motor housed in thedust filter 90 by operating an electric on/offswitch 81 connected to the motor via an electric wire passing inside theupper body 50 . This allows dirty air to flow from the dirty air inlet at the floor end 70 upwards into the duct located in thelower body 60 to thetangential inlet duct 91 from where it enters the dust chamber of thedust filter 90 .

在图4中可最好地看出由参考标记92标记的集尘室。经由切向入口管道91进入集尘室92的污浊空气以图4中箭头所示的顺时针方式绕圆柱形粗滤器93旋动。粗滤器93围绕并容纳更小的圆柱形细滤器30，使得在它们之间，粗滤器93和细滤器30用于连续滤出与污浊空气一起夹带的更小颗粒的尘垢，从而开始将这些尘垢收集到集尘室92中。集尘室92的端面包括安装在铰链99上并通过一系列门销95关闭的门94，门销被设计为与灰尘过滤部90的轮缘上的相应唇缘接合。当门94关闭时，设置在细滤器30的端面上的过滤器清洁装置的一系列第一部件96与设置在门94的内表面上的过滤器清洁装置的相应系列的第二部件97接合。当经由设置在门94外表面上的轮(在图4中不可见，但在图6中用940标记出)关闭门时，这些第一和第二部件96、97的接合允许使用者操作过滤器清洁装置。由聚乙烯、橡胶或类似弹性材料制成、设置在门94的圆周附近的弹性密封元件98保证门以气密方式关闭。The dust chamber marked byreference numeral 92 can best be seen in FIG. 4 .

Theprimary filter 93 surrounds and houses the smaller cylindricalfine filter 30 such that between them theprimary filter 93 and thefine filter 30 serve to successively filter out the smaller particles of dirt entrained with the dirty air, thereby beginning to remove them Collected indust collection chamber 92. The end face of thedust collection chamber 92 includes adoor 94 mounted onhinges 99 and closed by a series of door pins 95 designed to engage corresponding lips on the rim of thedust filter 90 . When thedoor 94 is closed, a series offirst parts 96 of filter cleaning means disposed on the end face of thefine filter 30 engages a corresponding series ofsecond parts 97 of filter cleaning means disposed on the inner surface of thedoor 94 .

The bottom view of FIG. 8 also shows thedirty air inlet 270 of thevacuum cleaner 200 .

图9示出了从集尘室292中拆下的过滤组件230，以展示出容纳在过滤组件230中的可透气马达壳体218。马达壳体218又包括图9中未示出的马达，马达壳体218具有形成在其端面中的多个第一通气孔280以允许通过过滤组件230的洁净空气进入马达壳体。图10的分解图示出了手持真空吸尘器200的主要内部部件。如图10所示，主体部分260和手柄280由两个半哈壳261、262组成。这展示出污浊空气入口270如何经由整体模制到下半哈壳262中的管道273与集尘室292置于流动相通。管道273被成型为提供通向集尘室292的切向入口。位于管道273任一侧的下半哈壳262内的空间用于容纳经由电线266电连接到插头充电器插槽268的多个可充电电池264。这使得可利用传统可插拔插头充电器265(其不是构成真空吸尘器200的部分)为电池264组再充电。电池264还经由电线282与安装在手柄280中的电接通/断开开关281电连接。电接通/断开开关281具有盖284以将开关与使用者绝缘。电池264和接通/断开开关281还经由电线216与马达10电连接，使得当使用者操作接通/断开开关281时，通过电池264启动马达10，带动安装在马达输出轴12上的风扇20开始旋转并将污浊空气向上吸入管道273。马达输出轴12被支承在轴承22上以防止其振动。马达10自身容纳在壳体218中。为易于制造壳体218设有一单独的端盖220。壳体218、220又容纳在位于集尘室292内部的过滤组件230中。过滤组件230具有截头圆锥形的形状，用作与集尘室292相配合的旋风分离器。FIG. 9 shows filter assembly 230 removed fromdust collection chamber 292 to revealbreathable motor housing 218 housed withinfilter assembly 230 . Themotor housing 218 , which in turn includes a motor not shown in FIG. 9 , has a plurality of first vent holes 280 formed in its end face to allow clean air passing through thefilter assembly 230 to enter the motor housing. The exploded view of FIG. 10 shows the main internal components of thehandheld vacuum cleaner 200 . As shown in FIG. 10 , themain body portion 260 and thehandle 280 are composed of two half shells 261 , 262 . This demonstrates how thedirty air inlet 270 is placed in flow communication with thedust chamber 292 via a duct 273 integrally molded into the lower housing half 262 . Duct 273 is shaped to provide tangential access todust chamber 292 . The space within the lower housing half 262 on either side of the conduit 273 is used to accommodate a plurality of rechargeable batteries 264 electrically connected to a plug charger socket 268 via electrical cords 266 . This makes it possible to recharge the battery pack 264 using a conventional pluggable plug charger 265 (which does not form part of the vacuum cleaner 200).

To allow a user to reclose thedoor 294 after emptying the dust chamber, thedoor 294 is provided with a door pin 250 that engages a lip formed on the rim of thedust chamber 292 .

最后转到图11，图中示出了根据本发明的包括马达、风扇和过滤器装置的真空吸尘器的第三实施例，该真空吸尘器是手持真空吸尘器300。如图11所示，真空吸尘器300包括主体部360、手柄380、和被设计成在其中容纳过滤组件330的集尘室392，在图11中示出了过滤组件330从集尘室392中拆下。当安装在集尘室392中时，过滤组件330和集尘室392都与主体部分360的纵轴垂直定向，使得在真空吸尘器的使用期间，集尘室392和过滤组件330基本保持水平，并且灰尘聚集到集尘室392的下侧中。集尘室392是透明的，以使使用者在真空吸尘器的运行期间能够观察到绕过滤组件330旋动的灰尘并且还能看到集尘室392何时充满而因此需要倒空。Turning finally to FIG. 11 , there is shown a third embodiment of a vacuum cleaner comprising a motor, fan and filter arrangement according to the invention, which is a hand-heldvacuum cleaner 300 . As shown in FIG. 11, thevacuum cleaner 300 includes amain body portion 360, ahandle 380, and adust chamber 392 designed to accommodate afilter assembly 330 therein. Thefilter assembly 330 is shown disassembled from thedust chamber 392 in FIG. Down. When installed in thedust collection chamber 392, both thefilter assembly 330 and thedust collection chamber 392 are oriented perpendicular to the longitudinal axis of themain body portion 360 such that during use of the vacuum cleaner, thedust collection chamber 392 and thefilter assembly 330 remain substantially horizontal and Dust collects into the underside of thedust collection chamber 392 . Thedust chamber 392 is transparent so that the user can observe the dust swirling around thefilter assembly 330 during operation of the vacuum cleaner and also see when thedust chamber 392 is full and therefore needs to be emptied.

图11还示出了如何利用铰接在其端面上的门394可以将集尘室392倒空。图11还显示出了容纳在过滤组件330内部的可透气马达壳体318。马达壳体318又包括图11中未示出的马达，该马达壳体318具有形成在其端面的多个通气孔380以允许通过过滤组件330的洁净空气进入马达壳体。Figure 11 also shows how thedust chamber 392 can be emptied by means of adoor 394 hinged on its end face. FIG. 11 also shows thebreathable motor housing 318 housed inside thefilter assembly 330 . Themotor housing 318 , which in turn includes a motor not shown in FIG. 11 , has a plurality of vent holes 380 formed in its end face to allow clean air passing through thefilter assembly 330 to enter the motor housing.

真空吸尘器300能够以类似于同样以本申请人的名义在欧洲专利公开No.1752076A中说明的方式绕集尘室392的中心轴转动。因此如图12A至图12C所示，真空吸尘器300可如图12B和图12C中的箭头所示的那样从图12A中示出的180度位置折叠到图12B中示出的360度位置，以便于例如存储和运输，或者折叠到图12C中示出的135度位置以例如允许进入不便接近的角落。图12C还显示了真空吸尘器300的污浊空气入口370。Thevacuum cleaner 300 is rotatable about the central axis of thedust collection chamber 392 in a manner similar to that described in European Patent Publication No. 1752076A also in the applicant's name. Thus, as shown in FIGS. 12A to 12C, thevacuum cleaner 300 can be folded from the 180-degree position shown in FIG. 12A to the 360-degree position shown in FIG. 12B as indicated by the arrows in FIGS.

The space within thelower body member 362 below theduct 373 is occupied by a plurality ofrechargeable batteries 364 which are electrically connected to aplug charger socket 368 viaelectrical wires 366 . This makes it possible to recharge thebattery pack 364 using a conventional pluggable plug charger 365 (which does not form part of the vacuum cleaner 300). Thebattery 364 is also electrically connected via anelectrical wire 382 to an electrical on/offswitch 381 mounted in thehandle 380 . The electrical on/offswitch 381 has acover 384 to insulate the switch from the user. Thebattery 364 and the on/offswitch 381 are also electrically connected to themotor 10 via theelectric wire 316, so that when the user operates the on/offswitch 381, themotor 10 is started by thebattery 364 and driven to be installed on themotor output shaft 12 Thefan 20 starts to spin and draws the dirty air upwards into theduct 373. Because thevacuum cleaner 300 can be rotated in the manner described above with respect to FIGS. A pair ofcorresponding rails 389 in thedust collection chamber 392 are in sliding contact. Thus, regardless of the orientation of themain body 360 relative to thehandle 380 , an electrical circuit can always be established between thebattery 364 , the on/offswitch 381 and themotor 10 .

从图13中还可看到，设置在远离马达10的马达输出轴12末端的轴承22支承马达输出轴12以防止其振动。马达10自身被容纳在壳体318中。为易于制造壳体318设有一单独的端盖320，在端盖320中可看到通气孔380，以允许通过过滤组件330的洁净空气进入马达壳体。壳体318、320又容纳在位于集尘室392内部的过滤组件330中。过滤组件330具有截头圆锥形的形状，用作与集尘室392相配合的旋风分离器。It can also be seen from FIG. 13 that the bearing 22 disposed at the end of themotor output shaft 12 remote from themotor 10 supports themotor output shaft 12 to prevent it from vibrating. Themotor 10 itself is housed in ahousing 318 . For ease ofmanufacture housing 318 is provided with aseparate end cap 320 in which ventholes 380 are visible to allow clean air throughfilter assembly 330 to enter the motor housing.Housings 318 , 320 are in turn housed infilter assembly 330 located insidedust collection chamber 392 . Thefilter assembly 330 has a frusto-conical shape and acts as a cyclone separator that cooperates with thedust collection chamber 392 .

图13还示出了集尘室392的门394，门394具有弹簧门销344，可靠弹簧346的弹力按下门销344将门394打开。门销344与形成在集尘室392轮缘上的唇缘接合以允许将门重新关闭。门通过由聚乙烯、橡胶或类似弹性材料制成的弹性密封元件398密封，以便保证门394以气密方式关闭。因此，在真空吸尘器300的运行期间，从污浊空气入口370经由管道373进入集尘室392的污浊空气绕过滤组件330旋动，并且通过过滤组件330的洁净空气被风扇20吸入通过可透气的马达壳体318，在将洁净空气从形成在半哈壳385中的多个洁净空气出口通气孔390排出之前，风扇20引导空气通过形成在与门394相对的集尘室的端面中的多个孔391。为了允许使用者调节主体360相对于手柄380的角度，最后，半哈壳386还设有棘轮350，棘轮350具有形成于其内圆周的多个齿。这些动作将主体360锁定在相对于手柄380的多个方位之一。棘轮350还设有弹簧释放按钮352，可靠弹簧354的弹力按下按钮352以使齿脱离，从而允许使用者将主体360从一个方位转动到另一方位。释放按钮352还将主体360重新锁定在相对于手柄380的新方位。FIG. 13 also shows adoor 394 of thedust collection chamber 392, thedoor 394 has aspring door pin 344, and thedoor 394 can be opened by pressing thedoor pin 344 under the elastic force of thespring 346.
