Japanese Patent Laying-Open No. 2005-261518 (page 1-9, FIG. 1)

  However, in the above vacuum cleaner, in order to remove dust attached to the filter, the dust collecting part is detached from the main body of the vacuum cleaner, the filter is removed from the dust collecting part, and the brush is moved along the filter by hand. Since there is a need, three work steps are required.

  Further, since the brush is provided in the filter, the number of parts is increased, and since the brush is provided in the filter so as to be movable along the filter, a guide member for guiding the movement of the brush is necessary and complicated. It is made into the composition.

  Therefore, an object of the present invention is to provide a vacuum cleaner that can remove dust adhering to a filter by a simple operation without requiring a complicated configuration.

  In order to solve the above-described problems, the present invention provides a dust collecting portion that is formed in a dust collecting chamber and is detachably provided on the cleaner main body, and the vacuum cleaner main body to apply a negative pressure to the dust collecting chamber.

  A hose guide tube 32 is provided on the front side of the main body case 18. The hose guide tube 32 is located in front of the container housing chamber 22 and communicates the suction connection port 12 to which one end of the dust collecting hose 14 can be attached with the container housing chamber 22. When the dust container 26 is inserted into the container housing chamber 22, the hose guide tube 32 communicates with a suction opening 35 of the dust container 26 described later and the suction connection port 12.

  On the front side of the main body case 18, an engagement recess 18 a that can be engaged with an engagement claw 33 a of a fixing means 33 of the dust collecting container 26 described later is formed.

  As shown in FIGS. 4 to 6, the dust collection container 26 inserted into the container storage chamber 22 has a shape that fits the container storage chamber 22 as a whole, and a dust collection chamber 34 (see FIG. 2) inside. I have.

  In a state where the dust collecting container 26 is housed in the container housing chamber 22 of the main body case 18, the rear end upper side wall 26 a is vertically aligned with the lattice member 31 disposed in the front opening 30 of the main body case 18 at a close position. It is formed along a surface that is inclined upstream of the direction.

  Further, the dust collection container 26 is provided with a suction opening 35 in the front wall portion 26b when viewed in a state accommodated in the container accommodation chamber 22 (see FIG. 1), and a discharge port 36 (see FIG. 2 and FIG. 5). For this reason, the dust collection chamber 34 communicates with the outside through the suction opening 35 or the discharge opening 36.

  Further, when the dust collecting container 26 is inserted into the container housing chamber 22 of the cleaner body 11, the suction opening 35 communicates with one end of the dust collecting hose 14 attached to the suction connection port 12. The discharge port 36 communicates with the front opening 30 in which the lattice member 31 is disposed. As shown in FIG. 2, a first filter 37 and a second filter 38 are provided in the dust collection chamber 34.

  The first filter 37 is made of a mesh member, and is provided so as to partition the dust collection chamber 34 into a first dust collection chamber portion 34 a and a second dust collection chamber portion 34 b at the approximate center of the dust collection chamber 34. For this reason, the dust taken into the first dust collection chamber portion 34a together with the air through the suction opening 35 is substantially prevented from entering the second dust collection chamber portion 34b.

  The second filter 38 is formed in a bellows shape so that the crest portions 39 and the trough portions 40 are alternately adjacent to increase the surface area. The 2nd filter 38 is attached to the discharge port 36 of the rear end upper side wall 26a, and the surface 38a is exposed to the dust collection chamber 34 (refer FIG. 2). Here, a portion protruding to the surface 38 a side exposed to the dust collection chamber 34 is a valley portion 40.

  In the present embodiment, the second filter 38 has a plate shape along the surface on which the discharge port 36 exists with a substantially constant thickness dimension as a whole, and each peak portion 39 is located on a substantially equal surface and each The valley portions 40 are located on substantially the same surface, and both surfaces are parallel to the surface where the front opening 30 is located. Further, in the second filter 38, each crest portion 39 and each trough portion 40 are alternately adjacent to each other along the direction in which the dust collecting container 26 is inserted into and removed from the main body case 18 (the attaching / detaching direction (see arrow P in FIG. 2)) In other words, the ridgeline of each peak portion 39 is attached to the dust collecting container 26 so as to be orthogonal to the direction in which the dust collecting container 26 is inserted into and removed from the main body case 18. The second filter 38 captures fine dust contained in the air that has passed through the first filter 37 and entered the second dust collecting chamber 34b.

  A fixing means 33 is provided on the front side of the dust collecting container 26. The fixing means 33 includes an engaging claw 33a that is biased forward and protrudes from the front side of the dust collecting container 26, and a fixing release button 33b. The fixing means 33 is configured to pull back the engaging claws 33a that protrude in the normal time when the fixing release button 33b is pressed. The fixing means 33 is provided at a position where the engaging claw 33a can be fitted into an engaging recess 18a provided on the front side of the main body case 18 (see FIG. 1).

  Guide protrusions 27 are provided on both side surfaces of the dust collecting container 26. The guide protrusion 27 extends in parallel with the front opening 30 in which the lattice member 31 is arranged in a state where the dust collecting container 26 is accommodated in the container accommodating chamber 22, and is formed on the inner wall surface 22 a of the container accommodating chamber 22. It is possible to fit into the provided guide groove 24. The guide protrusion 27 cooperates with the guide groove 24 to define the direction in which the dust collection container 26 is attached to and detached from the container storage chamber 22, and the dust collection when the dust collection container 26 is stored in the container storage chamber 22. The backlash of the container 26 is suppressed. For this reason, when the dust collection container 26 is pulled out from the main body case 18, the rear end upper side wall 26 a (second filter 38) of the dust collection container 26 is relatively displaced from the lattice member 31 while maintaining a certain proximity state. Will be moved as follows.

  A disposal opening 41 (see FIG. 2) is provided in the bottom wall of the dust collecting container 26 (the bottom wall of the dust collecting chamber 34), and the disposal opening 41 can be opened and closed by a lid 42. The lid 42 is rotatably attached to one side wall of the dust collecting container 26, and is sealed to the disposal opening 41 by being fixed to a fixing portion (not shown) with the disposal opening 41 being closed. It is supposed to be configured. A fixing portion (not shown) for fixing the disposal opening 41 is configured to release the fixed state when the dust disposal opening / closing operation button 43 is pressed. In the dust collecting container 26, when the dust disposal opening / closing operation button 43 is pressed in a posture in which the lid 42 is vertically downward, the lid 42 released from the fixed state is rotated by its own weight, and the bottom of the dust collecting chamber 34 The side is opened (see FIG. 6).

  In this embodiment, the inclined upper wall 26c of the dust collecting container 26 is formed so as to be orthogonal to the front opening 30 on which the lattice member 31 is disposed, and a container grip 44 is provided. Therefore, the dust collecting container 26 is released from the fixing unit 33 by pressing the fixing release button 33b, and then holding the container gripping part 44 and pulling it out in the direction along the guide groove 24 of the container housing chamber 22, thereby It can be removed from the main body 11.

  The dust collecting container 26 is inserted in the direction along the guide groove 24 from the attachment / detachment opening 23 of the main body case 18, and the engaging claw 33 a of the fixing means 33 is fitted in the engaging recess 18 a of the main body case 18. The vacuum cleaner main body 11 can be attached.

In addition to the above-described configuration, in the vacuum cleaner 10 according to the present invention, as shown in FIG. The hitting portion 45 is provided so as to protrude from the front opening 30 toward the container housing chamber 22 so as to come into contact with each mountain portion 39 of the second filter 38 when the dust collecting container 26 is extracted from the container housing chamber 22. In addition, each valley portion 40 is extended to the side of each valley portion 40 from the surface on which each mountain portion 39 is located. In this embodiment, as shown in FIG. 3, the hitting portion 45 is provided integrally with the lattice member 31 so as to be positioned at two places above the lattice member 31 disposed in the front opening 30. Projecting in a direction orthogonal to the surface of the member 31.
[Operation]
Next, operation | movement of the vacuum cleaner 10 is demonstrated.

  First, as shown in FIG. 2, the dust collection container 26 is attached to the container housing chamber 22 of the cleaner body 11, and the dust collection hose 14 is connected to the suction connection port 12 of the cleaner body 11 as shown in FIG. 1. At the same time, the suction port body 16 is connected to the hand operation tube 13 via the extension tube 15.

  Then, the power cord 17 is pulled out and the power plug 17a is connected to an outlet (not shown).

  In this state, the electric blower 19 is driven by operating the operation switch 13b of the operation portion 13a of the hand operation tube 13, and the suction port body 16 travels back and forth on the floor surface.

  By driving the electric blower 19, air is sucked in from the connection air passage portion 29, a negative pressure is applied to the dust collection chamber 34 provided in the dust collection container 26, and this negative pressure is further passed through the hose guide pipe 32. Acts on the dust collecting hose 14, the extension pipe 15 and the suction port body 16, and dust is sucked together with air from the suction port body 16.

  The sucked dust and air are sucked into the suction connection port 12 of the dust collecting container 26 through the extension pipe 15 and the dust collecting hose 14. The dust and air sucked into the suction connection port 12 are introduced into the first dust collection chamber portion 34 a of the dust collection chamber 34 through the hose guide tube 32 and the suction opening 35. The air introduced into the first dust collection chamber portion 34a goes to the second dust collection chamber portion 34b through the first filter 37. At this time, the dust may pass through the first filter 37. It is suppressed and accumulated in the lower part of the first dust collecting chamber 34a. The air that has passed through the first filter 37 and has been introduced into the second dust collecting chamber portion 34 b travels through the second filter 38 to the connection air passage portion 29. At this time, fine dust that has passed through the first filter 37 together with air is captured by the second filter 38 and is prevented from entering the connection air passage portion 29. The air sucked into the connection air passage portion 29 passes through the electric blower 19 and is exhausted to the outside of the cleaner body 11 (see the arrow W indicated by a broken line in FIG. 2).

  In the vacuum cleaner 10, the dust collecting container 26 is removed from the cleaner main body 11 (main body case 18) in order to discard the dust accumulated in the dust collecting chamber 34 (two-dot chain line dust collecting container shown in FIG. 2). 26). At this time, the dust collection container 26 is pulled out from the cleaner body 11 along the extending direction of the guide groove 24 by the guide groove 24 and the guide protrusion 27 (see arrow P in FIG. 2). The second filter 38 provided at the discharge port 36 is moved along the front opening 30 of the main body case 18.

  Here, in the vacuum cleaner 10 of the present embodiment, since the hitting portion 45 is provided in the lattice member 31 provided in the front opening 30, when the second filter 38 is moved along the front opening 30, The crest portions 39 are sequentially hit by the hitting portion 45 from the back surface 38 b side of the second filter 38. Therefore, the second filter 38 is attached to the dust collecting container 26 to close the dust collecting chamber 34 and is hit by the hitting portion 45 from the back surface 38b with the front surface 38a exposed to the dust collecting chamber 34. As a result, the fine dust attached by capturing is shaken off and accumulated in the lower part of the dust collecting chamber 34 without falling outside the dust collecting chamber 34.

  For example, when the removed dust collecting container 26 is held on a trash can and the opening / closing operation button 43 is pressed, the lid 42 that has sealed the disposal opening 41 of the dust collecting container 26 is rotated by its own weight. Thus, the disposal opening 41, that is, the dust collecting chamber 34 is opened (see FIG. 6). For this reason, the dust accumulated in the lower portion of the dust collection chamber 34, that is, the lower portion of the first dust collection chamber portion 34a and the lower portion of the second dust collection chamber portion 34b can be discarded. After the dust is discarded, the dust collecting container 26 is reinserted into the container housing chamber 22 of the cleaner body 11 (main body case 18) with the lid 42 closed.

  In the vacuum cleaner 10 according to the present invention, the dust on the second filter 38 can be removed only by performing an easy operation of removing the dust collection container 26 from the cleaner body 11.

  Further, since the second filter 38 is attached to the dust collecting container 26 and the front surface 38a is exposed to the dust collecting chamber 34, the second filter 38 is hit by the hitting portion 45 from the back surface 38b. The dust can be shaken off, and the fine dust that has been dropped can be stored in the lower part of the second dust collection chamber 34b.

  Further, the hitting portion 45 strikes the back surface 38b of the second filter 38 attached to the dust collecting container 26 and having the surface 38a exposed to the dust collecting chamber 34, thereby adhering to the surface 38a exposed to the dust collecting chamber 34. The dust collecting chamber 34 is closed in the scene where the dust is dropped, because the dust is dropped into the dust collecting chamber 34 (second dust collecting chamber portion 34b). It is possible to prevent the dust removed from 38 from falling to the surroundings, that is, the dust removed from the second filter 38 from being scattered outside the dust collection chamber 34.

  Since the dust collection container 26 is removed from the cleaner body 11 in order to discard the dust accumulated in the dust collection chamber 34, if the amount of accumulated dust increases due to use, the cleaner body 11 Since it will be removed, dust will be removed if the adhesion amount of the dust to the 2nd filter 38 increases. For this reason, it is possible to keep the second filter 38 from being clogged only by using it for cleaning without particularly performing an operation for removing dust from the second filter 38.

  Since the dust on the second filter 38 can be removed simply by removing the dust collecting container 26 from the cleaner body 11, the second filter 38 can be removed from the dust collecting container 26, or the brush can be removed by hand. Therefore, it is possible to remove dust without polluting the surroundings and the hands of the operator.

  Since the second filter 38 extends along the front opening 30 when the dust collecting container 26 is attached to the cleaner body 11, the vertical direction in the state in which the cleaner body 11 is installed on a horizontal plane. In this case, the dust that has been shaken off can be prevented from adhering to the second filter 38 again. For this reason, it is desirable that the degree of inclination of the second filter 38 is set in consideration of the inclination angle of each peak portion 39 and each valley portion 40.

  In the second filter 38, each crest portion 39 is sequentially hit by the hitting portion 45, so that vibration is given not only to the location where the hit is actually made but also to the whole by continuous hitting input. Dust can be dropped.

  Since it is not necessary to remove the second filter 38 from the dust collecting container 26 in order to remove dust, it is possible to prevent the operator's hands from becoming dirty.

  The second filter 38 is provided in the dust collecting container 26 so as to be movable at a position close to the wall surface of the container housing chamber 22 when being taken out from the main body case 18, and the tapping portion projects from the wall surface of the container housing chamber 22. 45, and the second filter 38 is easily dust-removed by adopting a configuration in which the crest portions 39 and the trough portions 40 are alternately adjacent to each other along the direction in which the dust collecting container 26 is inserted into and removed from the main body case 18. be able to.

  The second filter 38 is positioned so that each crest portion 39 is located on substantially the same plane parallel to the lattice member 31 and is kept relatively close to the lattice member 31 when the dust collecting container 26 is extracted. Since it is set as the structure moved so that it may slip | deviate, each peak part 39 can be made to hit reliably by the hit part 45 comprised as a protrusion of a fixed shape.

  Unlike the configuration in which the brush is movable along the filter as in a conventional vacuum cleaner when viewed in the air path from the dust collection chamber 34 to the electric blower 19, the hitting portion 45, which is a small protrusion, is provided on the filter. Since the configuration is provided, an increase in air path resistance can be suppressed. In particular, in the above-described embodiment, the hitting portion 45 is formed in the lattice member 31 so as to protrude in a direction orthogonal to the surface of the lattice member 31 disposed in the front opening 30, and thus the electric blower 19 from the dust collection chamber 34. When viewed in the direction of the flow of wind, the wind path resistance is not increased because it exists on the lattice member 31.

  Therefore, in the vacuum cleaner 10 of this invention, the dust adhering to a filter can be removed by simple operation | work, without requiring a complicated structure.

  The hitting portion 45 is composed of a protrusion provided integrally with the lattice member 31. However, when the dust collecting container 26 is extracted from the container housing chamber 22, In the embodiment, as long as it hits each crest portion 39) of the second filter 38, it may be formed of a leaf spring, for example, and is not limited to the above-described embodiment. When the hitting portion 45 is formed of a leaf spring, it is desirable that the hitting portion 45 be formed of a material having greater rigidity than the bellows-like filter.

  In the above-described embodiment, the hitting portion 45 is configured to be able to hit all the crest portions 39 of the bellows-like second filter 38, but the bellows-like shape is used to drop dust attached to the second filter 38. It is only necessary to be able to strike a plurality of mountain portions by utilizing this, and is not limited to the above-described embodiment.

  In the embodiment described above, the dust collection container 26 is shown as a dust collection unit that forms the dust collection chamber 34 and is detachable from the cleaner body 11, but forms a dust collection chamber in which dust is collected, and As long as it can be attached to and detached from the cleaner body 11 and the bellows-like filter is provided so as to be exposed to the dust collecting chamber, it may be, for example, a bag-like one, and is limited to the above-described embodiment. Is not to be done.

  In the above-described embodiment, the dust collection container 26 is configured to be extracted in a straight line and removed from the container housing chamber 22. As long as each mountain portion is hit, it is not limited to the above-described embodiment.

  The dust collecting chamber of the vacuum cleaner may not be provided with the first filter 37, and is not limited to the above-described embodiment.

  In the above embodiment, the canister type vacuum cleaner has been described. However, the present invention can be applied to an upright type vacuum cleaner or a vacuum cleaner in which a dust separation unit is attached to a hand control tube or the like.

  In the above embodiment, as an example, an electric vacuum cleaner having a configuration in which the upper surface of the dust collecting container accommodated in the container accommodating chamber is a part of the upper surface of the vacuum cleaner main body is described, but the container accommodating chamber is provided with a lid, The container storage chamber may be closed by closing the lid in a state where the dust container is accommodated, and the upper surface of the lid may be a part of the upper surface of the cleaner body. It is not limited to.
