电动吸尘器electric vacuum cleaner

技术领域technical field

本发明涉及在吸尘器主体上具有能够伸缩的管部的电动吸尘器。The present invention relates to an electric vacuum cleaner having an expandable pipe portion on a vacuum cleaner main body.

背景技术Background technique

在清扫使用者的生活空间的尘埃的电动吸尘器的技术领域中，为了提高使用者的使用便利性，提出有各种结构。例如，关于纵型的电动吸尘器，提出有在使用者清扫生活空间之后而收纳电动吸尘器时，将管多段地收纳而收纳于主体内部的结构。作为这样的电动吸尘器，例如公知具有图9、图10A、图10B所示的结构的电动吸尘器。图9是以往的电动吸尘器的概略结构图。图10A是表示图9所示的电动吸尘器的手柄单元伸出的状态的说明图。图10B是表示图9所示的电动吸尘器的手柄单元收缩的状态的说明图。In the technical field of electric vacuum cleaners for cleaning dust in a user's living space, various configurations have been proposed in order to improve user-friendliness. For example, regarding a vertical type vacuum cleaner, when the user stores the vacuum cleaner after cleaning the living space, a structure in which pipes are stored in multiple stages inside the main body has been proposed. As such an electric vacuum cleaner, what has the structure shown to FIG. 9, FIG. 10A, and FIG. 10B is known, for example. Fig. 9 is a schematic configuration diagram of a conventional electric vacuum cleaner. Fig. 10A is an explanatory view showing a state in which the handle unit of the electric vacuum cleaner shown in Fig. 9 is extended. Fig. 10B is an explanatory view showing a state in which the handle unit of the electric vacuum cleaner shown in Fig. 9 is contracted.

在该电动吸尘器中，在手柄56中收纳有第1连结管57，在第1连结管57内收纳有第2连结管58。而且，能够这样在手柄56内收纳有第1连结管57、第2连结管58的状态下使手柄56与吸尘器主体50结合。这样的电动吸尘器例如被公开于日本特开2008-80043号公报。In this vacuum cleaner, afirst connection pipe 57 is accommodated in ahandle 56 , and asecond connection pipe 58 is accommodated in thefirst connection pipe 57 . And thehandle 56 can be connected with the cleaner main body 50 in the state which accommodated the1st connection pipe 57 and the2nd connection pipe 58 in thehandle 56 in this way. Such an electric vacuum cleaner is disclosed, for example, in JP-A-2008-80043.

可是，即使是这样的电动吸尘器，在使用者使用电动吸尘器后而收纳电动吸尘器时，从紧凑地进行收纳的方面来看还是存在改善的余地。即，由于在手柄56内收纳有第1连结管57，所以需要在手柄56内设置用于收纳第1连结管57的空间。因此，手柄56变长。因此，在手柄单元收缩并收纳于吸尘器主体50中的状态下，从吸尘器主体50突出的手柄56的长度较长。其结果，从地面到手柄56的上端的高度较高，收纳电动吸尘器所需的空间较大。However, even with such an electric vacuum cleaner, when the user stores the electric vacuum cleaner after using the electric vacuum cleaner, there is still room for improvement in terms of compact storage. That is, since the first connectingpipe 57 is accommodated in thehandle 56 , it is necessary to provide a space for accommodating the first connectingpipe 57 in thehandle 56 . Therefore, thehandle 56 becomes longer. Therefore, the length of thehandle 56 protruding from the cleaner body 50 is long in a state where the handle unit is shrunk and housed in the cleaner body 50 . As a result, the height from the ground to the upper end of thehandle 56 is high, and the space required to house the electric vacuum cleaner is large.

集尘软管9的第1端与主体部2的上部连接，第2端与操作管3的后端部(第1端)连接。集尘软管9在第1端侧，利用连接部9A与主体部2相连，而且利用设于主体部2内的风道9B与集尘室6连通。即，集尘软管9与操作管3和集尘室6连通。The first end of thedust collection hose 9 is connected to the upper portion of themain body 2 , and the second end is connected to the rear end (first end) of theoperation pipe 3 . Thedust collection hose 9 is connected to themain body 2 by theconnection part 9A at the first end side, and communicates with thedust collection chamber 6 by theair duct 9B provided in themain body 2 . That is, thedust collection hose 9 communicates with theoperation pipe 3 and thedust collection chamber 6 .

在操作管3的后部设有供使用者保持操作管3的把手部10。此外，在操作管3的后端部(第1端)连接有集尘软管9，在另一端(第2端)连接有第2管11。At the rear of theoperation tube 3 is provided agrip portion 10 for the user to hold theoperation tube 3 . Moreover, thedust collection hose 9 is connected to the rear end part (1st end) of theoperation pipe 3, and the2nd pipe 11 is connected to the other end (2nd end).

操作管3能够进退地与第2管11的第1端连接，操作管3的一部分被收纳在第2管11的内部。此外，在第2管11的第2端连接有第3管16。Theoperation pipe 3 is connected to the first end of thesecond pipe 11 so as to be able to advance and retreat, and a part of theoperation pipe 3 is accommodated inside thesecond pipe 11 . Moreover, the3rd pipe 16 is connected to the 2nd end of the2nd pipe 11. As shown in FIG.

在第2管11的操作管3侧(第1端侧)设有滑动连结体17。如图3B所示，在滑动连结体17上设有由作为弹性体的弹簧22支承的伸缩动作按钮18。A slidingconnection body 17 is provided on theoperation pipe 3 side (first end side) of thesecond pipe 11 . As shown in FIG. 3B , atelescopic operation button 18 supported by aspring 22 which is an elastic body is provided on the slidingcoupling body 17 .

根据该结构，因为操作管3在第2管11内进退移动，第2管11进退，所以在使用者按压伸缩动作按钮18时，操作管3能够进退移动。此外，在使用者解除对伸缩动作按钮18的按压时，操作管3被锁定(临时固定)在该位置。According to this structure, since theoperation pipe 3 moves forward and backward in thesecond pipe 11 and thesecond pipe 11 advances and retreats, when the user presses thetelescopic operation button 18, theoperation pipe 3 can move forward and backward. In addition, when the user releases the pressing of thetelescopic operation button 18, theoperation tube 3 is locked (temporarily fixed) at this position.

此外，滑动连结体17在第2管11和操作管3安装在主体部2上的状态下从主体部2的连接开口13向外部露出。因此在该状态下，设于滑动连结体17的伸缩动作按钮18作为主体部2的外部轮廓的一部分向主体部2的前表面侧暴露。In addition, the slidingconnection body 17 is exposed to the outside from the connection opening 13 of themain body part 2 in a state where thesecond pipe 11 and theoperation pipe 3 are attached to themain body part 2 . Therefore, in this state, thetelescopic operation button 18 provided on the slidingcoupling body 17 is exposed to the front surface side of themain body part 2 as a part of the outer contour of themain body part 2 .

而且，如图3B所示，在滑动连结体17的主体部2侧设有用于将第2管11卡合于主体部2的安装凹部12。通过由使用者将第2管11插入主体部2的连接开口13，安装凹部12和设于连接开口13内的卡合突出部(未图示)卡合，第2管11安装在主体部2的长度方向的大致整个区域。安装凹部12和卡合突出部(未图示)的卡合通过使用者扳动解除杆15而被解除。Furthermore, as shown in FIG. 3B , anattachment recess 12 for engaging thesecond pipe 11 with themain body 2 is provided on the side of themain body 2 of the slidingcoupling body 17 . When the user inserts thesecond pipe 11 into the connection opening 13 of themain body 2, the mountingrecess 12 engages with the engaging protrusion (not shown) provided in theconnection opening 13, and thesecond pipe 11 is attached to themain body 2. Approximately the entire area in the lengthwise direction. The engagement between the mounting recessedportion 12 and the engaging protrusion (not shown) is released when the user pulls therelease lever 15 .

第3管16能够滑动地插入第2管11内，在第2管11内部与操作管3连通。特别是在此，表示了第3管16收纳于操作管3内的例子。Thethird pipe 16 is slidably inserted into thesecond pipe 11 and communicates with theoperation pipe 3 inside thesecond pipe 11 . In particular, an example in which thethird tube 16 is accommodated in theoperation tube 3 is shown here.

如图3A所示，在第3管16和第2管11相连结的部分设有滑动连结部19。另外，在滑动连结部19上设有按钮20。在使用者按压按钮20时，第3管16能够滑动移动，第3管16在第2管11内滑动移动而从第2管11露出。此外，在使用者解除对按钮20的按压时，第3管16被锁定(临时固定)在该位置。As shown in FIG. 3A , a slidingconnection portion 19 is provided at a portion where thethird pipe 16 and thesecond pipe 11 are connected. In addition, abutton 20 is provided on theslide coupling portion 19 . When the user presses thebutton 20 , thethird tube 16 can slide and move, and thethird tube 16 slides inside thesecond tube 11 and is exposed from thesecond tube 11 . In addition, when the user releases thepush button 20, thethird pipe 16 is locked (temporarily fixed) at this position.

在第2管11插入主体部2的连接开口13的状态下，第2管11的顶端部被密封在主体部2的内部。因此，如图2所示，在利用吸入口体1清扫地面的情况下，吸入口体1和集尘室6经由旋转管4和连接部5连通。In a state where thesecond tube 11 is inserted into the connection opening 13 of themain body 2 , the distal end portion of thesecond tube 11 is sealed inside themain body 2 . Therefore, as shown in FIG. 2 , when cleaning the floor with thesuction port body 1 , thesuction port body 1 communicates with thedust collecting chamber 6 via therotary pipe 4 and the connectingportion 5 .

另一方面，如图4所示，在从主体部2取下收纳有操作管3的第2管11而进行清扫的情况下，因为主体部2处于立起状态，所以从吸入口体1到集尘室6的流路切断。而且，从第3管16经由第2管11、操作管3和集尘软管9到集尘室6的流路被连通。On the other hand, as shown in FIG. 4 , when thesecond pipe 11 housing theoperation pipe 3 is removed from themain body 2 for cleaning, since themain body 2 is in an upright state, from thesuction port body 1 to the The flow path of thedust collecting chamber 6 is cut off. And the flow path from the3rd pipe 16 to thedust collection chamber 6 via the2nd pipe 11, theoperation pipe 3, and thedust collection hose 9 is connected.

接着，说明电动吸尘器100的动作、作用。如图2所示，在利用吸入口体1清扫地面的情况下，使用者首先按压伸缩动作按钮18，使操作管3的、收纳于第2管11内部的部分露出，使操作管3的把手部10位于使用者易操作的高度位置。然后，使用者打开电源开关21，电动鼓风机7被驱动，集尘室6内的空气被电动鼓风机7抽吸。通过该抽吸，集尘室6内成为负压。Next, the operation and function ofelectric vacuum cleaner 100 will be described. As shown in Figure 2, in the case of using thesuction port body 1 to clean the ground, the user first presses thetelescopic action button 18 to expose the part of theoperation pipe 3 that is housed in thesecond pipe 11, and make the handle of theoperation pipe 3 Theportion 10 is located at a height that is easy for the user to operate. Then, the user turns on thepower switch 21 , theelectric blower 7 is driven, and the air in thedust collecting chamber 6 is sucked by theelectric blower 7 . By this suction, the inside ofdust collecting chamber 6 becomes a negative pressure.

该负压作用于旋转管4和吸入口体1的吸入室，尘埃和空气一起从吸入室的吸入开口被抽吸。被抽吸到吸入室的空气和尘埃经由旋转管4被向主体部2的集尘室6抽吸，尘埃被收集在集尘过滤器中。此时，只要使用者如所示图2那样把持操作管3的把手部10而使主体部2前后移动，就能够清扫地面等。此时，安装在主体部2上的第2管11的顶端部被封闭。The negative pressure acts on therotary pipe 4 and the suction chamber of thesuction port body 1, and the dust and air are sucked together from the suction opening of the suction chamber. The air and dust sucked into the suction chamber are sucked into thedust collection chamber 6 of themain body 2 via therotary pipe 4, and the dust is collected in the dust collection filter. At this time, as shown in FIG. 2 , the user can clean the floor and the like by holding thehandle portion 10 of theoperation pipe 3 and moving themain body portion 2 back and forth. At this time, the distal end portion of thesecond pipe 11 attached to themain body portion 2 is closed.

此外，如图4所示，在从主体部2取下收纳有操作管3的第2管11而进行清扫的情况下，使用者首先在立起主体部2的状态下扳动设于主体部2上部的解除杆15。根据该操作，安装凹部12和卡合突出部的锁定被解除，能从主体部2取下收纳有操作管3的第2管11。之后，使用者按压伸缩动作按钮18和按钮20，使操作管3和第3管16成为使用者容易操作的长度，用第3管16进行清扫。In addition, as shown in FIG. 4 , when cleaning thesecond pipe 11 containing theoperation pipe 3 from themain body 2 , the user first pulls thesecond pipe 11 provided on themain body 2 while themain body 2 is standing upright. 2. Theupper release lever 15. According to this operation, the lock between the attachment recessedportion 12 and the engaging protrusion is released, and thesecond pipe 11 in which theoperation pipe 3 is accommodated can be removed from themain body portion 2 . After that, the user presses theretractable operation button 18 and thebutton 20 to make theoperation tube 3 and thethird tube 16 into a length that the user can easily operate, and then uses thethird tube 16 to perform cleaning.

这样，在从主体部2取下了第2管11的状态下，从吸入口体1到集尘室6的流路被切断。因此，被从第3管16的顶端部抽吸的空气和尘埃经由第2管11、操作管3和集尘软管9被向主体部2的集尘室6抽吸。Thus, in the state which removed the2nd pipe 11 from themain body part 2, the flow path from thesuction port body 1 to thedust collection chamber 6 is blocked. Therefore, the air and dust sucked from the distal end of thethird pipe 16 are sucked into thedust collection chamber 6 of themain body 2 via thesecond pipe 11 , theoperation pipe 3 , and thedust collection hose 9 .

如图1所示，在使用者结束清扫而收纳电动吸尘器时，使用者按压按钮20，将第3管16收纳于第2管11内，按压伸缩动作按钮18将操作管3的一部分收纳于第2管11内。然后，将第2管11插入主体部2的连接开口13，将第2管11收纳于设于主体部2的长度方向的大致整个区域的收纳部23内。这样，使用者能将电动吸尘器100收纳为紧凑的状态。这样，主体部2优选具有用于沿主体部2的长度方向能够装卸地收纳第2管11的收纳部23。根据该构造，能在主体部2的长度方向上收纳第2管11，能够使在主体部2收纳有收纳了操作管3的第2管11的状态下的电动吸尘器100的收纳高度降低。As shown in Figure 1, when the user finishes cleaning and stores the electric vacuum cleaner, the user presses thebutton 20 to store thethird tube 16 in thesecond tube 11, and presses thetelescopic action button 18 to store a part of theoperation tube 3 in thesecond tube 11. 2tubes 11 inside. Then, thesecond tube 11 is inserted into the connection opening 13 of themain body 2 , and thesecond tube 11 is accommodated in thestorage portion 23 provided in substantially the entire lengthwise direction of themain body 2 . In this way, the user can storeelectric vacuum cleaner 100 in a compact state. In this way, themain body part 2 preferably has thestorage part 23 for detachably storing thesecond tube 11 along the longitudinal direction of themain body part 2 . According to this structure, thesecond pipe 11 can be accommodated in the longitudinal direction of themain body 2 , and the storage height of theelectric vacuum cleaner 100 can be reduced in a state where thesecond pipe 11 housing theoperation pipe 3 is accommodated in themain body 2 .

而且，优选收纳部23设于主体部2的长度方向的大致整个区域。即，优选收纳部23在主体部2的长度方向上尽可能长地设置。例如优选遍及主体部2的长度方向的80％以上长度地设置收纳部23。由此，能在主体部2的长度方向上的大致整个区域收纳第2管11，能够使在主体部2收纳有收纳了操作管3的第2管11状态下的电动吸尘器的高度降低。Furthermore, it is preferable that thestorage portion 23 is provided in substantially the entire area in the longitudinal direction of themain body portion 2 . That is, it is preferable that thestorage portion 23 is provided as long as possible in the longitudinal direction of themain body portion 2 . For example, theaccommodating part 23 is preferably provided over 80% or more of the length in the longitudinal direction of themain body part 2 . Thereby, thesecond pipe 11 can be accommodated substantially in the entire longitudinal direction of themain body 2 , and the height of the electric vacuum cleaner can be reduced in a state where thesecond pipe 11 housing theoperation pipe 3 is accommodated in themain body 2 .

如以往的电动吸尘器那样，在做成在操作管3的内部收纳第2管11的结构的情况下，需要在操作管3内部设置用于收纳第2管11的空间。因此，操作管3的全长变长。由此，从主体部2突出的操作管3的长度变长，在主体部2中收纳有操作管3的状态下的电动吸尘器的收纳高度变高。In the case of a configuration in which thesecond pipe 11 is housed inside theoperation pipe 3 as in conventional electric vacuum cleaners, it is necessary to provide a space for housing thesecond pipe 11 inside theoperation pipe 3 . Therefore, the overall length of theoperation tube 3 becomes longer. Thereby, the length of theoperation pipe 3 protruding from themain body part 2 becomes long, and the storage height of the electric vacuum cleaner in the state which accommodated theoperation pipe 3 in themain body part 2 becomes high.

然而，如上述那样，通过使操作管3的一部分收纳于从操作管3能够进退地伸出的第2管11的内部，能够使在主体部2中收纳有第2管11的状态下的高度降低。其结果，能够不占位置地将电动吸尘器100紧凑地收纳于室内的角落。此外，即使在主体部2中不设收纳部23的情况下，也能使管部分紧凑。However, as described above, by accommodating a part of theoperation pipe 3 inside thesecond pipe 11 extending forward and backward from theoperation pipe 3 , the height of the state where thesecond pipe 11 is housed in themain body 2 can be adjusted. reduce. As a result,vacuum cleaner 100 can be compactly stored in a corner of the room without occupying a space. In addition, even in the case where thestorage portion 23 is not provided in themain body portion 2, the pipe portion can be made compact.

此外，在第2管11被安装在主体部2上的状态下，第2管11的滑动连结体17和伸缩动作按钮18成为从主体部2的连接开口13向外部暴露的状态。因此，使用者能够用一只手握住操作管3的把手部10，用另一只手保持主体部2，同时操纵伸缩动作按钮18。因此，使用者能通过一次接触(1次动作)就使操作管3从主体部2伸缩。此外，在操作管3上设有能够进退地被连接的第2管11，在第2管11上设有伸缩动作按钮18。因此，即使在从主体部2取下第2管11而进行清扫的情况下，使用者也能够用一只手握住操作管3的把手部10，用另一只手保持伸缩的第2管11，同时操纵伸缩动作按钮18。因此，能通过一次接触(1次动作)进行伸缩操作。In addition, when thesecond pipe 11 is attached to themain body 2 , the sliding joint 17 and thetelescopic operation button 18 of thesecond pipe 11 are exposed to the outside from the connection opening 13 of themain body 2 . Therefore, the user can hold thehandle portion 10 of theoperation tube 3 with one hand and manipulate thetelescopic operation button 18 while holding themain body portion 2 with the other hand. Therefore, the user can expand and contract theoperation tube 3 from themain body 2 with one touch (one operation). In addition, asecond pipe 11 connected so as to be able to advance and retreat is provided on theoperation pipe 3 , and atelescopic operation button 18 is provided on thesecond pipe 11 . Therefore, even when thesecond tube 11 is removed from themain body 2 for cleaning, the user can hold thehandle 10 of theoperation tube 3 with one hand and hold the second tube that expands and contracts with the other hand. 11. Manipulate thetelescoping action button 18 at the same time. Therefore, telescopic operation can be performed by one touch (one operation).

此外，在操作管3上设有能够伸缩地伸出的第2管11，而且在第2管11上设有能够伸缩地伸出的第3管16。在该结构中，优选第3管16和操作管3在第2管11的内部连通并被保持。即，优选即使在从第2管11拉出第3管16的状态下，第3管16的一端也能够进退地与操作管3的内部连接。利用该结构，在从主体部2拔出第2管11，操作管3、第2管11和第3管16伸出的情况下，能使在各管内流动的尘埃顺畅地流动。而且，能可靠地在各管的端部处保持各管，能确保强度。In addition, asecond pipe 11 that can extend telescopically is provided on theoperation pipe 3 , and athird pipe 16 that can extend telescopically is provided on thesecond pipe 11 . In this structure, it is preferable that thethird tube 16 and theoperation tube 3 are communicated and held inside thesecond tube 11 . That is, it is preferable that one end of thethird tube 16 is connected to the inside of theoperation tube 3 so as to be able to advance and retreat even when thethird tube 16 is pulled out from thesecond tube 11 . With this structure, when thesecond pipe 11 is pulled out from themain body 2 and theoperation pipe 3, thesecond pipe 11, and thethird pipe 16 protrude, the dust flowing in each pipe can be smoothly flowed. Also, each tube can be reliably held at the end of each tube, and strength can be ensured.

详细地说明，在做成在第2管11内部第3管16和操作管3不连通的结构的情况下，抽吸尘埃的流路成为如下的结构，即，尘埃从直径比较小的第3管16流入大径的第2管11内，之后，被从大径的第2管11向直径比第2管11小的操作管3内抽吸。因此，有可能妨碍尘埃的顺畅流动，且有可能由于尘埃的受阻、堵塞等而产生尘埃无法被抽吸到第2管11内部从而堆积这样的问题。Described in detail, in the case of a structure in which thethird pipe 16 and theoperation pipe 3 are not communicated inside thesecond pipe 11, the flow path for sucking dust becomes the following structure. Thetube 16 flows into the large-diametersecond tube 11 and is then sucked from the large-diametersecond tube 11 into theoperation tube 3 having a smaller diameter than thesecond tube 11 . Therefore, the smooth flow of the dust may be hindered, and there may be a problem that the dust cannot be sucked into thesecond pipe 11 and accumulates due to obstruction or clogging of the dust.

而且，在第3管16的端部和操作管3的端部在第2管11内部不连通、不被保持的情况下，第3管16的端部和操作管3的端部成为不被保持的自由端。因此，第3管16只由滑动连结部19保持，同样操作管3只由滑动连结体17保持。在该情况下，操作管3、第2管11、第3管16伸出时的管部全长的强度、刚性、保持力变弱，变得容易弯曲。And, when the end portion of thethird pipe 16 and the end portion of theoperation pipe 3 are not communicated in thesecond pipe 11 and are not held, the end portion of thethird pipe 16 and the end portion of theoperation pipe 3 are not connected. Keep the free end. Therefore, thethird pipe 16 is held only by the slidingconnection portion 19 , and theoperation pipe 3 is also held only by the slidingconnection body 17 . In this case, when theoperation tube 3 , thesecond tube 11 , and thethird tube 16 protrude, the strength, rigidity, and holding force of the entire length of the tube portion become weak and become easy to bend.

相反，在本实施方式中，第3管16的端部和操作管3的端部在第2管11内部被连通、保持。因此，能提高操作管3、第2管11和第3管16伸出时的管整体长度的强度。而且，由于抽吸尘埃的流路成为从直径比较小的第3管16向直径比第3管16大的操作管3内抽吸尘埃的结构，所以能够使尘埃顺畅地流动，防止尘埃受阻、堵塞。In contrast, in the present embodiment, the end of thethird tube 16 and the end of theoperation tube 3 are communicated and held inside thesecond tube 11 . Therefore, the strength of the entire pipe length when theoperation pipe 3 , thesecond pipe 11 , and thethird pipe 16 protrude can be improved. And since the flow path for sucking dust is a structure in which dust is sucked from thethird pipe 16 having a relatively small diameter to theoperation pipe 3 having a larger diameter than thethird pipe 16, the dust can be smoothly flowed to prevent the dust from being blocked, clogged.

此外，第3管16能够伸缩地从第2管11的第2端伸出。因此，能确保从主体部2拔出第2管11，操作管3、第2管和第3管16伸出时的管的全长较长。Moreover, the3rd pipe 16 protrudes from the 2nd end of the2nd pipe 11 telescopically. Therefore, when thesecond tube 11 is pulled out from themain body 2 and theoperation tube 3 , the second tube, and thethird tube 16 protrude, the overall length of the tube can be ensured to be long.

此外，在本实施方式中，伸缩动作按钮18具有由作为弹性体的弹簧22支承的按钮结构。因此，利用握住而保持主体部2或第2管11的操作，即，使用者利用像握住这样的1次的动作能够同时进行伸缩动作按钮18的操作。因此，使用者能容易地进行操作管3、第2管和第3管16的伸缩动作。假设在伸缩动作按钮18是滑动操作型按钮等情况下，存在如下那样的课题。即，如图2所示，在利用吸入口体清扫地面的情况、如图4所示在从主体部2取下第2管11而进行清扫的情况这两种情况下，使用者无法在握住而保持主体部2或第2管11的同时进行使伸缩动作按钮18滑动的操作。In addition, in this embodiment, thetelescopic operation button 18 has a button structure supported by aspring 22 which is an elastic body. Therefore, the operation of holding themain body portion 2 or thesecond pipe 11 by gripping, that is, the user can simultaneously operate theretractable operation button 18 by one action of gripping. Therefore, the user can easily perform expansion and contraction operations of theoperation tube 3 , the second tube, and thethird tube 16 . Assuming that the expansion andcontraction action button 18 is a slide operation type button, there are the following problems. That is, as shown in FIG. 2, in the case of cleaning the floor by using the suction port body, and in the case of removing thesecond pipe 11 from themain body 2 and cleaning as shown in FIG. The operation of sliding thetelescopic operation button 18 is performed while holding themain body 2 or thesecond pipe 11 .

另外，如图5的立体图所示，也可以用第2管30替代图4的结构中的第2管11和第3管16。即，也可以由操作管3和第2管30构成管部。In addition, as shown in the perspective view of FIG. 5 , thesecond pipe 30 may be used instead of thesecond pipe 11 and thethird pipe 16 in the structure of FIG. 4 . That is, the pipe portion may be constituted by theoperation pipe 3 and thesecond pipe 30 .

第2管30安装、收纳在形成于主体部2的长度方向的大致整个区域的收纳部23中。此外，在第2管30的顶端部形成有抽吸口，被从顶端部抽吸的空气和尘埃经由操作管3和集尘软管9被向主体部2的集尘室6抽吸。这样，第3管16不是必需的，通过不用第3管16，能廉价地构成电动吸尘器。Thesecond pipe 30 is attached and housed in thehousing part 23 formed in substantially the entire area in the longitudinal direction of themain body part 2 . In addition, a suction port is formed at the distal end of thesecond pipe 30 , and the air and dust sucked from the distal end are sucked into thedust collection chamber 6 of themain body 2 via theoperation pipe 3 and thedust collection hose 9 . In this way, thethird pipe 16 is not necessary, and by not using thethird pipe 16, an electric vacuum cleaner can be constructed at low cost.

(第2实施方式)(second embodiment)

图6是表示本发明的第2实施方式的电动吸尘器的主体部的连接开口部的立体图。图7是表示图6所示的电动吸尘器的主体部的局部侧视图。本实施方式的电动吸尘器在具有为了将管部容易收纳在设于主体部的收纳部中的构造这点上与第1实施方式不同。由于除此以外的构造和第1实施方式相同，因此仅对该特征部分的周边进行说明。6 is a perspective view showing a connection opening of a main body of a vacuum cleaner according to a second embodiment of the present invention. Fig. 7 is a partial side view showing a main body of the electric vacuum cleaner shown in Fig. 6 . The electric vacuum cleaner of the present embodiment is different from the first embodiment in that it has a structure for easily storing the pipe portion in the storage portion provided in the main body. Since the structure other than that is the same as that of the first embodiment, only the periphery of the characteristic part will be described.

如图6所示，本实施方式的电动吸尘器与第1实施方式相同，具有用于收容管部的收纳部23。收纳部23具有供管部插入的连接开口13。在连接开口13的周缘设有从连接开口13的周缘局部突出的引导部24。具体而言，在连接开口13周缘的解除杆15侧，设有突出形成于连接开口13的引导部24。因此，如图7所示，使用者在立起主体部2的状态下使管部的顶端即第3管16的顶端抵接引导部24，并且进行对位，从而能够容易地将第2管11和第3管16从连接开口13插入收纳部23。因此，使用者结束清扫，将操作管3和第3管16收纳到第2管11内之后，使用者能够容易将该状态下的管部插入主体部2的连接开口13。As shown in FIG. 6, the electric vacuum cleaner of this embodiment has thestorage part 23 for accommodating a pipe part similarly to 1st Embodiment. The receivingportion 23 has aconnection opening 13 into which the pipe portion is inserted. Aguide portion 24 partially protruding from the periphery of theconnection opening 13 is provided at the periphery of theconnection opening 13 . Specifically, aguide portion 24 protruding from theconnection opening 13 is provided on therelease lever 15 side of the periphery of theconnection opening 13 . Therefore, as shown in FIG. 7 , the user makes the top end of the pipe portion, that is, the top end of thethird pipe 16 abut against theguide portion 24 in the state where themain body portion 2 is erected, and performs alignment, so that the second pipe can be easily placed. 11 and thethird pipe 16 are inserted into thestorage portion 23 through theconnection opening 13 . Therefore, after the user finishes cleaning and stores theoperation tube 3 and thethird tube 16 in thesecond tube 11 , the user can easily insert the tube portion in this state into the connection opening 13 of themain body portion 2 .

另外，如图6、图7所示，优选在主体部2的上表面，将连接开口13、把手8、解除杆15和集尘软管9的连接部从前方朝向后方并排设于一条直线上。即，优选在主体部2的上表面设有连接开口13和用于保持主体部2的把手8，在把手8和连接开口13之间设有引导部24。根据该结构，在使用者用手握住把手8或将手放置在把手8上的情况下，能利用突出的引导部24防止管部的顶端即第3管16的顶端碰到手。In addition, as shown in Fig. 6 and Fig. 7, it is preferable that on the upper surface of themain body part 2, the connection parts of theconnection opening 13, thehandle 8, therelease lever 15 and thedust collection hose 9 are arranged on a straight line from the front to the rear. . That is, it is preferable that theconnection opening 13 and thehandle 8 for holding thebody part 2 are provided on the upper surface of themain body part 2 , and theguide part 24 is provided between thehandle 8 and theconnection opening 13 . According to this structure, when the user holds thehandle 8 with his hand or puts his hand on thehandle 8, the protrudingguide portion 24 can prevent the tip of the tube portion, that is, the tip of thethird tube 16 from touching the hand.

另外，在上述的结构中，还成为在连接开口13和解除杆15之间设有突出的引导部24的结构。即，在主体部2的上表面设有连接开口13和用于解除第2管11和主体部2的卡合的解除杆15，在连接开口13和解除杆15之间设有引导部24。因此，在使用者将手放置在解除杆15上等情况下，能利用引导部24防止第3管16的顶端碰到手。In addition, in the above-mentioned configuration, the protrudingguide portion 24 is also provided between theconnection opening 13 and therelease lever 15 . That is, aconnection opening 13 and arelease lever 15 for releasing the engagement between thesecond pipe 11 and thebody 2 are provided on the upper surface of themain body 2 , and aguide 24 is provided between theconnection opening 13 and therelease lever 15 . Therefore, when the user places his or her hand on therelease lever 15 , theguide portion 24 can prevent the tip of thethird pipe 16 from coming into contact with the hand.

另外，在上述的结构中，还成为在连接开口13与将集尘软管9和主体部2连接起来的连接部9A之间设有引导部24的结构。即，集尘软管9与主体部2的上表面连接，连接开口13设于主体部2的上表面，引导部24设于连接开口13与将集尘软管9和主体部2连接起来的连接部9A之间。由此，使管部的顶端抵接在连接开口13和连接部9A之间突出的引导部24，并且进行对位，从而能够容易地将管部插入连接开口13。Moreover, in the said structure, the structure which provided theguide part 24 between theconnection opening 13 and theconnection part 9A which connects thedust collection hose 9 and the main-body part 2 is also set. That is, thedust collection hose 9 is connected to the upper surface of themain body 2, theconnection opening 13 is located on the upper surface of themain body 2, and theguide 24 is located at theconnection opening 13 and the connection between thedust collection hose 9 and themain body 2. Between theconnection parts 9A. Thereby, the tip of the pipe portion is brought into contact with theguide portion 24 protruding between theconnection opening 13 and theconnection portion 9A and aligned, so that the pipe portion can be easily inserted into theconnection opening 13 .

接着，一边参照图8一边说明本实施方式的另一结构。图8是本实施方式的另一电动吸尘器的主体部的局部侧视图。Next, another configuration of this embodiment will be described with reference to FIG. 8 . Fig. 8 is a partial side view of a main body of another electric vacuum cleaner according to this embodiment.

在该结构中，在主体部2的上表面，连接开口13、把手8、解除杆15和集尘软管9的连接部9A从前方朝向后方并排设于一条直线上。引导部24突出地设于同集尘软管9的与主体部2相连接的连接部9A相对的一侧(主体部2的前方侧)的一部分连接开口13上。即，集尘软管9与主体部2的上表面连接，连接开口13设于主体部2的上表面，引导部24设于与将集尘软管9和主体部2连接起来的连接部9A相对的一侧。In this structure, on the upper surface of themain body part 2, theconnection part 9A which connects theopening 13, thehandle 8, therelease lever 15, and thedust collection hose 9 is arranged on a straight line from the front toward the rear. Theguide portion 24 protrudes from a part of theconnection opening 13 on the side (the front side of the main body 2 ) of thedust collection hose 9 opposite to theconnection portion 9A connected to themain body 2 . That is, thedust collection hose 9 is connected to the upper surface of themain body part 2, theconnection opening 13 is provided on the upper surface of themain body part 2, and theguide part 24 is provided on theconnection part 9A connecting thedust collection hose 9 and themain body part 2. opposite side.

该结构，也能通过管部的顶端即第3管16的顶端抵接引导部24，并进行对位，将管部容易地插入连接开口13。在该情况下，使用者使引导部24位于第3管16的顶端侧的前方。Also in this structure, the tip of the tube portion, that is, the tip of thethird pipe 16 abuts against theguide portion 24 and aligns, so that the tube portion can be easily inserted into theconnection opening 13 . In this case, the user positions theguide part 24 in front of the distal end side of thethird tube 16 .

以上，说明了本发明的第1、第2实施方式的电动吸尘器，但是本发明的电动吸尘器不限定于上述的实施方式的电动吸尘器。As mentioned above, although the electric vacuum cleaner of 1st, 2nd embodiment of this invention was demonstrated, the electric vacuum cleaner of this invention is not limited to the electric vacuum cleaner of said embodiment.

例如，在第2实施方式的电动吸尘器中，管部由操作管3、第2管11、第3管16构成。操作管3和第3管16被收纳于第2管11内，第2管11被收纳于收纳部23内。可是，管部的结构和管的收纳方法等不限定于此。例如也可以如用图5说明的那样，由操作管3和第2管11构成管部。只要是将管部收纳于主体部2的收纳部23内的结构即可。For example, in the electric vacuum cleaner of the second embodiment, the pipe portion is composed of theoperation pipe 3 , thesecond pipe 11 , and thethird pipe 16 . Theoperation tube 3 and thethird tube 16 are accommodated in thesecond tube 11 , and thesecond tube 11 is accommodated in thestorage portion 23 . However, the structure of the tube portion, the method of storing the tube, and the like are not limited thereto. For example, as described with reference to FIG. 5 , the pipe portion may be constituted by theoperation pipe 3 and thesecond pipe 11 . Any structure may be used as long as the pipe portion is housed in thehousing portion 23 of themain body portion 2 .

此外，在第2实施方式的电动吸尘器中，说明了以下的构件，即，引导部24设于连接开口13和把手8之间、连接开口13和解除杆15之间、连接开口13和集尘软管9之间以及与集尘软管9的连接部相对的一侧(主体部2的前方侧)中的任一个部位的一部分连接开口13上。除此以外，只要引导部24设于连接开口13的一部分即可，本发明的电动吸尘器不限定于此。In addition, in the electric vacuum cleaner according to the second embodiment, theguide part 24 is described as being provided between theconnection opening 13 and thehandle 8, between theconnection opening 13 and therelease lever 15, and between theconnection opening 13 and the dust collection lever. A portion of any one of the positions between thehoses 9 and the side opposite to the connection portion of the dust collection hose 9 (the front side of the main body 2 ) is connected to theopening 13 . In addition, what is necessary is just to provide theguide part 24 in a part of theconnection opening 13, and the electric vacuum cleaner of this invention is not limited to this.

例如，也可以将引导部24设于连接开口13和把手8之间以及同集尘软管9的与主体部2相连接的连接部相对的一侧(主体部2的前方侧)这两个部位。在该结构中，能发挥图7所示的引导部24和图8所示的引导部24这两者的效果。For example, theguide portion 24 may also be provided between theconnection opening 13 and thehandle 8 and on the side opposite to the connection portion of thedust collection hose 9 connected to the main body 2 (the front side of the main body 2). parts. In this configuration, both the effects of theguide portion 24 shown in FIG. 7 and theguide portion 24 shown in FIG. 8 can be exhibited.

另外，在以上的说明中，在主体部2之下设有吸入口体1，但是也可以不设置吸入口体1。即，也可以将上述的管部和收纳部应用于不具有使主体部2沿长度方向立起地清扫地面的功能、只利用管部清扫的类型的电动吸尘器。In addition, in the above description, thesuction port body 1 is provided under themain body part 2, but thesuction port body 1 may not be provided. That is, the above-described pipe portion and storage portion may be applied to a type of electric vacuum cleaner that does not have the function of cleaning the floor with themain body portion 2 standing upright in the longitudinal direction, and cleans only with the pipe portion.

如以上那样，本发明的电动吸尘器能够使在将操作管安装到主体部上，落地收纳在地面上的状态的收纳高度降低。因此，能较佳地应用于家庭、商业用等电动吸尘器的领域、用途。As described above, the electric vacuum cleaner according to the present invention can reduce the storage height in a state where the operation tube is attached to the main body and the vacuum cleaner is placed on the ground. Therefore, it can be suitably applied to fields and uses of electric vacuum cleaners such as household and commercial use.
