立式真空吸尘器的集尘器以及用于该集尘器的盖的支撑结构Dust collector for an upright vacuum cleaner and support structure for a cover of the dust collector

技术领域technical field

本发明涉及一种真空吸尘器。更具体地说，本发明涉及一种立式真空吸尘器的集尘器，该集尘器在上表面形成有吸气口和排气口，吸气口允许含杂质的空气穿过其引入，排气口允许净化空气排至其外部，从而保持真空吸尘器的吸力，同时确保集尘器的密闭性，本发明还涉及用于该集尘器的盖的支撑结构，该支撑结构通过使用过滤器而即使在真空吸尘器的驱动期间集尘器内的真空度增加时也适于防止盖的向下变形。The present invention relates to a vacuum cleaner. More specifically, the present invention relates to a dust collector for an upright vacuum cleaner, which is formed on an upper surface with a suction port and an exhaust port, the suction port allows air containing impurities to be introduced therethrough, and the exhaust port is exhausted. The air port allows clean air to be exhausted to the outside of it, thereby maintaining the suction of the vacuum cleaner while ensuring the airtightness of the dust collector. The invention also relates to a support structure for the cover of the dust collector, which is protected by the use of a filter. It is adapted to prevent downward deformation of the cover even when the degree of vacuum inside the dust collector increases during driving of the vacuum cleaner.

背景技术Background technique

根据形状和使用姿势，真空吸尘器通常可分为：罐式真空吸尘器，其便于角落清洁和移动，同时容易更换刷子和管嘴；以及立式真空吸尘器，其便于维护并且容易清洁较大空间。According to the shape and usage posture, vacuum cleaners are generally classified into: canister vacuum cleaners, which are convenient for corner cleaning and movement, and easy to replace brushes and nozzles; and upright vacuum cleaners, which are convenient for maintenance and easy to clean a large space.

图1是表示传统的立式真空吸尘器的立体图。FIG. 1 is a perspective view showing a conventional upright vacuum cleaner.

传统的立式真空吸尘器包括：抽吸头2，其用于吸入含有地板上杂质的空气；主体4，其安装在抽吸头2上并具有吸入空气的抽吸装置；以及把手6，其安装到主体4的上部而被使用者抓握。A conventional upright vacuum cleaner includes: a suction head 2 for sucking air containing impurities on the floor; a main body 4 which is mounted on the suction head 2 and has a suction device for sucking air; and a handle 6 which is mounted to the upper part of the main body 4 to be grasped by the user.

抽吸头2用于与真空吸尘器的操作相结合，在待清洁地板上移动的同时通过形成在抽吸头12的下表面处的吸气口吸入含杂质的空气。即，空气在接收在主体4内的抽吸装置的操作下通过抽吸头2的下表面被吸入。The suction head 2 is used to suck air containing impurities through a suction port formed at a lower surface of thesuction head 12 while moving on the floor to be cleaned in conjunction with the operation of the vacuum cleaner. That is, air is sucked through the lower surface of the suction head 2 under the operation of the suction device received in the main body 4 .

主体4的下部铰接到抽吸头2的后侧，从而主体4可相对于抽吸头2向后倾斜预定角度。The lower portion of the main body 4 is hinged to the rear side of the suction head 2 so that the main body 4 can be inclined backward at a predetermined angle relative to the suction head 2 .

主体4的上部设有把手6，从而使用者可抓握把手并在清洁操作期间操纵整个真空吸尘器。The upper part of the main body 4 is provided with a handle 6 so that a user can grasp the handle and manipulate the whole vacuum cleaner during cleaning operations.

例如，在进行对于目标位置的清洁操作期间，使用者抓握把手6，并调节主体4相对于抽吸头2的倾角。For example, the user grasps the handle 6 and adjusts the inclination angle of the main body 4 relative to the suction head 2 during a cleaning operation for a target position.

集尘器8可拆卸地安装到主体4的前部中央。集尘器8对通过抽吸头流到该集尘器的空气中所含的杂质进行过滤，并将过滤的杂质收集在其中。A dust collector 8 is detachably mounted to the front center of the main body 4 . The dust collector 8 filters impurities contained in the air flowing into the dust collector through the suction head, and collects the filtered impurities therein.

对于图中所示的传统真空吸尘器，集尘器示出为收集以气旋方式抽吸的空气中所含的杂质。For the conventional vacuum cleaner shown in the figure, the dust collector is shown to collect impurities contained in the cyclonic suctioned air.

对于如上所述构造的传统立式真空吸尘器内的气流，含有杂质的空气首先借助于接收在主体4中的抽吸装置的操作通过形成在抽吸头2的下表面处的吸气口被抽吸。For the airflow in the conventional upright vacuum cleaner constructed as described above, the air containing impurities is first sucked through the suction port formed at the lower surface of the suction head 2 by means of the operation of the suction device received in the main body 4 suck.

然后，空气经由主体4流入集尘器8。在杂质在集尘器8内从空气清除的情况下，将空气经由主体4通过排气口从集尘器8排至外部。Then, the air flows into the dust collector 8 via the main body 4 . In the case where impurities are removed from the air inside the dust collector 8 , the air is exhausted from the dust collector 8 to the outside through the exhaust port through the main body 4 .

同时，图2是表示图1的集尘器的立体图。参照图2，集尘器8在上部形成有吸气口21，在下部形成有排气口22。Meanwhile, FIG. 2 is a perspective view showing the dust collector of FIG. 1 . Referring to FIG. 2 , the dust collector 8 is formed with anair inlet 21 at its upper portion and anexhaust port 22 at its lower portion.

然而，如果集尘器在上部形成吸气口并在下部形成排气口，那么在吸气口侧由于在真空吸尘器的驱动期间真空度的增加而引起遮蔽力增大，就会导致真空吸尘器的吸力降低。However, if the dust collector forms the suction port at the upper part and the exhaust port at the lower part, the shielding force increases due to an increase in the degree of vacuum during driving of the vacuum cleaner on the suction port side, resulting in a Suction is reduced.

图3是表示传统的立式真空吸尘器的集尘器的剖视图。Fig. 3 is a sectional view showing a dust collector of a conventional upright vacuum cleaner.

如图3所示，传统立式真空吸尘器的集尘器用于在将杂质从穿过该集尘器的空气过滤之后收集杂质，并且使空气在被其中的过滤器过滤之后可以排至外部。As shown in FIG. 3 , a dust collector of a conventional upright vacuum cleaner serves to collect impurities after filtering them from air passing through the dust collector, and allows the air to be discharged to the outside after being filtered by a filter therein.

为了执行该功能，集尘器10具有穿过覆盖容器体11的上部的盖12形成的吸气口和排气口，盖12在其下表面设有引导件13，引导件13将通过吸气口引入的空气朝向容器体11引导，同时将通过容器体11净化的空气朝向排气口引导。In order to perform this function, thedust collector 10 has a suction port and an exhaust port formed through acover 12 covering the upper part of thecontainer body 11. Thecover 12 is provided with aguide 13 on its lower surface, and theguide 13 will pass through the suction port. The air introduced by the port is guided toward thecontainer body 11, while the air purified by thecontainer body 11 is directed toward the exhaust port.

此外，过滤器14附接至引导件13的下表面以净化污染的空气。In addition, afilter 14 is attached to the lower surface of theguide 13 to purify polluted air.

因此，当污染空气在穿过盖的吸气口之后在容器体的内部沿着引导件螺旋流动的同时，超过预定重量的杂质落到容器体的底部上，并且空气在通过过滤器净化之后沿着引导件通过盖的排气口被排至外部。Therefore, while polluted air flows spirally along the guide inside the container body after passing through the suction port of the cover, impurities exceeding a predetermined weight fall on the bottom of the container body, and the air passes through the filter after being purified along the The guide is exhausted to the outside through the exhaust port of the cover.

然而，当真空度根据真空吸尘器的驱动而增加时，盖的排气口被压缩，从而导致盖的边缘变宽并且盖的中央区域向下变形。结果，不能充分确保集尘器的密封。However, when the degree of vacuum increases according to the driving of the vacuum cleaner, the exhaust port of the cover is compressed, causing the edges of the cover to widen and the central area of the cover to deform downward. As a result, the sealing of the dust collector cannot be sufficiently ensured.

因此，需要一种克服以上问题的改进的真空吸尘器。Therefore, there is a need for an improved vacuum cleaner that overcomes the above problems.

根据本发明的立式真空吸尘器的集尘器具有筒形形状，并在上端设有盖20。The dust collector of the upright vacuum cleaner according to the present invention has a cylindrical shape and is provided with acover 20 at the upper end.

盖20为圆形，并形成有吸气口21和排气口22，设置到真空吸尘器的主体(未示出)上的吸气管和排气管分别接合到吸气口21和排气口22。Thecover 20 has a circular shape and is formed with asuction port 21 and anexhaust port 22 to which a suction pipe and an exhaust pipe provided to a main body (not shown) of the vacuum cleaner are joined, respectively. twenty two.

引导件30附接到盖20的下表面以引导空气的流径。引导件30具有直径比盖20的直径小的盘形，并且与吸气口21和排气口22连通。Aguide 30 is attached to a lower surface of thecover 20 to guide a flow path of air. Theguide 30 has a disc shape with a diameter smaller than that of thecover 20 , and communicates with thesuction port 21 and thedischarge port 22 .

过滤器40附接到引导件30的下表面，筒形容器体50附接到盖20的下表面的周边。Thefilter 40 is attached to the lower surface of theguide 30 , and thecylindrical container body 50 is attached to the periphery of the lower surface of thecap 20 .

这里，引导件30和过滤器40位于容器体50内的上部，在容器体50中杂质与通过吸气口21引入集尘器的空气分离，并且下沉至底部，同时空气在被过滤器40净化之后通过排气口22排出。Here, theguide 30 and thefilter 40 are located in the upper part of thecontainer body 50, and in thecontainer body 50, the impurities are separated from the air introduced into the dust collector through thesuction port 21, and sink to the bottom, while the air is filtered by thefilter 40. After purification, it is discharged through theexhaust port 22.

引导件30包括将通过盖20的吸气口21引入的空气引导成在容器体50内螺旋旋转的吸气引导部31，以及将朝向过滤器40的中央排出的净化空气引导至盖20的排气口22的排气引导部32。Theguide 30 includes anair suction guide 31 that guides air introduced through theair suction port 21 of thecover 20 to spirally rotate inside thecontainer body 50 , and guides the purified air discharged toward the center of thefilter 40 to the exhaust air of thecover 20 .Exhaust guide 32 ofair port 22 .

作为一实施例，吸气引导部31包括将引入空气引导成沿着引导件30的边缘旋转流动的吸气引导板31a以及在吸气引导板31a的远端形成的倾斜板31b，穿过倾斜板31b形成有倾斜开口。As an example, thesuction guide part 31 includes asuction guide plate 31a that guides the incoming air to rotate and flow along the edge of theguide 30, and aninclined plate 31b formed at the distal end of thesuction guide plate 31a, passing through theinclined plate 31a. Theplate 31b is formed with inclined openings.

穿过倾斜板31b形成的倾斜开口用于将通过吸气引导板31a引入的空气自然而然地引导至容器体50。The inclined opening formed through theinclined plate 31 b serves to naturally guide the air introduced through thesuction guide plate 31 a to thecontainer body 50 .

排气引导部32包括排气孔32b和排气引导板32a，被过滤器净化的空气通过排气孔32b排至外部，排气引导板32a将通过排气孔32b排出的空气引导至盖20的排气口22。Theexhaust guide part 32 includes anexhaust hole 32b and anexhaust guide plate 32a through which the air purified by the filter is exhausted to the outside, and theexhaust guide plate 32a guides the air exhausted through theexhaust hole 32b to thecover 20 Theexhaust port 22.

优选的是，本发明的集尘器还包括位于引导件30与盖20之间的垫圈60，以防止空气通过它们之间的间隙泄漏。Preferably, the dust collector of the present invention further includes agasket 60 between theguide 30 and thecover 20 to prevent air from leaking through the gap therebetween.

垫圈60设计成直径大于盖20的直径，从而增强盖20和引导件30的密封力，同时增强由盖20与容器体50之间的接合而产生的密封力。Thegasket 60 is designed to have a diameter larger than that of thecap 20 so as to enhance the sealing force of thecap 20 and theguide 30 while enhancing the sealing force generated by the engagement between thecap 20 and thecontainer body 50 .

另外，肋20a从盖20的下表面分别对应于吸气口21和排气口22突出。In addition,ribs 20 a protrude from the lower surface of thecover 20 corresponding to thesuction port 21 and thedischarge port 22 , respectively.

也就是说，一个肋20a从吸气口21延伸以将穿过吸气口21引入的空气引导至引导件30的吸气引导部31，而另一个肋20a从排气口22延伸以将空气从排气引导部32引导至排气口22从而通过排气口22排气。That is, onerib 20a extends from thesuction port 21 to guide the air introduced through thesuction port 21 to thesuction guide portion 31 of theguide 30, and theother rib 20a extends from theexhaust port 22 to guide the air It is guided from theexhaust guide portion 32 to theexhaust port 22 to be exhausted through theexhaust port 22 .

此时，每个肋20a都为筒形，并且长度不同。具体地说，对于与吸气口21对应的肋20a，肋20a的与吸气引导部31的吸气引导板31a接触的部分比肋20a的其它部分延伸得更多。同样，对于与排气口22对应的肋20a，肋20a的与排气引导部32的排气引导板32a接触的部分比肋20a的其它部分延伸得更多。At this time, eachrib 20a is cylindrical and has different lengths. Specifically, with respect to therib 20a corresponding to thesuction port 21, the portion of therib 20a that is in contact with thesuction guide plate 31a of thesuction guide portion 31 extends more than the other portion of therib 20a. Also, for therib 20a corresponding to theexhaust port 22, the portion of therib 20a that is in contact with theexhaust guide plate 32a of theexhaust guide portion 32 extends more than the other portion of therib 20a.

下面将描述根据本发明的集尘器的操作和效果。The operation and effect of the dust collector according to the present invention will be described below.

立式真空吸尘器的主体(未示出)的吸气管接合到安装在集尘器上端上的盖20的吸气口21，主体的排气管接合到盖的排气口22。A suction pipe of a main body (not shown) of the upright vacuum cleaner is joined to asuction port 21 of acover 20 installed on an upper end of the dust collector, and an exhaust pipe of the main body is joined to anexhaust port 22 of the cover.

在这种状态下，在真空吸尘器操作时，通过真空吸尘器的抽吸头(未示出)吸入的含有灰尘和其它杂质的空气通过盖20的吸气口21沿着引导件30的吸气引导部31引入容器体50。In this state, when the vacuum cleaner is in operation, the air containing dust and other impurities sucked by the suction head (not shown) of the vacuum cleaner is guided along the suction of theguide 30 through thesuction port 21 of thecover 20.Portion 31 is introduced intocontainer body 50 .

换言之，空气在穿过吸气口21之后，沿着吸气引导部31的吸气引导板31a在引导件30内流通，自然而然地穿过形成在倾斜板31b中的倾斜开口向下运动，并流动至容器体50。引入容器体50的空气在其中以螺旋形状流通。In other words, the air, after passing through thesuction port 21, circulates inside theguide 30 along thesuction guide plate 31a of thesuction guide portion 31, naturally moves downward through the inclined opening formed in theinclined plate 31b, and Flow to thecontainer body 50. The air introduced into thecontainer body 50 circulates therein in a spiral shape.

空气的螺旋流通向引入容器体50的空气施加离心力。The spiral flow of air applies centrifugal force to the air introduced into thecontainer body 50 .

离心力用于使超过预定重量的杂质下落到容器体40的底部上，同时迫使引入的空气在容器体50内流通而不是直接朝过滤器40流动。The centrifugal force is used to drop impurities exceeding a predetermined weight onto the bottom of thecontainer body 40 while forcing the introduced air to circulate within thecontainer body 50 instead of flowing directly toward thefilter 40 .

因此，超过预定重量的杂质收集在容器体50的底部上，同时空气在向上运动并被过滤器40净化之后通过引导件30的排气引导部32排至外部。Accordingly, impurities exceeding a predetermined weight are collected on the bottom of thecontainer body 50 while air is exhausted to the outside through theexhaust guide portion 32 of theguide 30 after being moved upward and purified by thefilter 40 .

这样，空气在被过滤器40净化之后，穿过与在过滤器40中央处的空隙空间连通的排气引导部32的排气孔32b，通过排气引导板32a流动至盖20的排气口22，并通过主体的排气管排至外部。Thus, the air, after being purified by thefilter 40, passes through theexhaust hole 32b of theexhaust guide portion 32 communicating with the void space at the center of thefilter 40, and flows to the exhaust port of thecover 20 through the exhaust guide plate 32a. 22, and exhausted to the outside through the exhaust pipe of the main body.

同时，布置在盖20与引导件30之间的垫圈60用于防止空气泄漏。此外，形成在盖20的下表面上的肋20a具有可变的长度，并且分别紧密接触吸气引导板31a和排气引导板32a，从而在提供空气流道的同时确保吸气口和排气口的密封。Meanwhile, thegasket 60 disposed between thecover 20 and theguide 30 serves to prevent air leakage.
