Description

  The present invention relates to a dust collecting device for collecting dust in the air that is applied to a vacuum cleaner and sucked in particular.

  A vacuum cleaner for cleaning dust such as a floor surface sucks air and collects dust in the sucked air in a dust collector.

  The dust collector is provided with a filter for collecting dust in the air and exhausting clean air. This filter is clogged by collecting dust, and there is a concern about a reduction in suction force. Therefore, a dust removal mechanism for exchanging the filter or removing the collected dust is provided.

  The dust removal mechanism vibrates a filter, for example, and removes adhering dust by vibration. For example, the thing of patent document 1 uses a handle which carries a vacuum cleaner main body, operates a dust removal mechanism, and removes dust by vibrating a filter by this.

  In particular, as a dust removal mechanism, a dust removal mechanism is constructed by linking a rotatable handle (handle) accommodated in the main body of the vacuum cleaner so that it can be erected to function as a handle from the stored state. The dust removing member to be moved is moved with respect to the filter formed in a pleat shape. During this movement, the filter is vibrated by bringing the dust removing member into contact with the peak portion of the pleated filter. Moreover, in the operation | movement which accommodates a handle, it is the structure which improves a dust removal effect using that the moving direction of a dust removal member reverses.

  According to the dust removal mechanism of the filter described in Patent Document 1, the configuration becomes very large. In particular, it cannot be applied as it is to a self-propelled robot cleaner as described in Patent Document 2. In other words, unlike the ordinary vacuum cleaner described in Patent Document 1, the robot cleaner is extremely capable of cleaning a narrow space that cannot be cleaned, such as an area that cannot be artificially entered, such as under a bed. It is thin and flat.

  Therefore, a handle is not provided to carry the cleaner, but the cleaner itself runs and cleans itself. Therefore, a handle for carrying the vacuum cleaner main body is not usually provided. There is also no power supply coat.

  As described above, the filter dust removal mechanism described in Patent Document 1 cannot be applied to a robot cleaner as described in Patent Document 2 as it is.

  However, if the filter is not removed, cleaning cannot be performed due to clogging of the filter. Therefore, replacement of the filter is forced every time. This exchange also places an economic burden on the user. In addition, the replacement work is forced to the user and is not easy to maintain.

  Therefore, providing the filter with a dust removing mechanism is a very important factor for continuously using the vacuum cleaner. In particular, in a robot cleaner, unlike a normal cleaner that is manually operated, the capacity for collecting dust cannot be increased, and the same applies to a filter. Therefore, a dust removal mechanism suitable for a self-propelled cleaner is required instead of the dust removal mechanism described in Patent Document 1.

  Further, the dust removal mechanism described in Patent Document 1 is separate from the dust collection device and the dust removal mechanism, and in a state where the dust collection device is taken out from the cleaner body in order to discard the collected dust, The dust removal mechanism is in the main body of the vacuum cleaner, and the dust removal operation cannot be performed at present.

  In the dust removal mechanism described in Patent Document 1, a plurality of rows of contact portions that contact the filter are arranged and moved in opposite directions. However, it is necessary to repeat the movement by the operation of taking out the stored handle and the storing operation. For this reason, it is necessary to repeatedly store and release the handle for carrying the cleaner while the dust collector is housed in the cleaner body.

  Therefore, if the dust collector is removed from the cleaner body, the dust removal operation cannot be performed. Therefore, the operation becomes very troublesome.

  Moreover, the dust removal mechanism is very complicated. That is, a mechanism for interlocking with the action of the handle, a mechanism for moving a member for vibrating the filter, particularly a rack, a plurality of gears, etc. need to be efficiently meshed, and the design tends to be complicated. .

  The present invention provides a dust collector that enables dust removal operation even when the dust collector is housed in or removed from the cleaner body.

  An object of this invention is to provide a dust collector provided with the dust removal mechanism suitable also for the robot cleaner by a self-propelled type.

  The present invention provides a dust collector including a filter dust removal mechanism that can be applied not only to a robot cleaner but also to a general vacuum cleaner.

  An object of the present invention is to provide a dust removal mechanism that can be applied to a dust collector having a small dust collection capacity.

  Furthermore, an object of this invention is to provide a dust collector provided with the dust removal mechanism which raises dust removal efficiency further by manual operation.

  Furthermore, the present invention provides a dust removal mechanism using a simple mechanism.

  In order to achieve the above-mentioned object, the dust collector of the present invention is provided with a filter on the upper part of the dust collector that constitutes the dust collector that collects dust. This filter covers the opening of the dust collecting container and collects dust contained in the air.

  The upper part of the filter is provided with an upper cover that holds the filter and forms an exhaust space through which airflow sucked into the dust collecting container passes through the filter and communicates with the exhaust port of the cleaner body. A dust removing mechanism for removing dust adhering to the filter is provided between the upper cover and the exhaust surface of the filter, that is, the upper cover.

  Moreover, since the dust removal mechanism is provided in the upper cover, filter dust removal can be performed even when the dust collector is attached to the cleaner body or removed from the cleaner body.

  The dust removing mechanism is provided with a plurality of moving parts movable with respect to the filter, and these moving parts are moved in opposite directions. The moving portion is provided with a contact portion that constitutes a vibration member. The moving unit is configured to move in conjunction with an operation of an operation unit that can be manually operated, and each moving body moves in the opposite direction, so that it is expected that the dust removing effect is enhanced.

  In addition, the operation unit is provided with an interlocking mechanism for enabling the moving body to move in the opposite directions by an operation in one direction. By this interlocking mechanism, one moving part reciprocates and the other moving mechanism interlocks the operation so that the moving direction is reciprocally reversed.

  By moving in directions opposite to each other, the contact portion comes into contact with the filter, the effect of vibrating the filter is enhanced, and the dust removal efficiency can be further improved.

  Moreover, even if the operation direction of the operation unit is one operation, the moving body can be reciprocated in the opposite directions. Thereby, manual operation becomes easy and dust removal efficiency can be improved.

  According to the dust collector equipped with the dust removal mechanism of the present invention, the dust removal efficiency of the filter can be improved by a simple operation.

  Further, since the dust collecting mechanism is provided in the dust collecting device, filter dust can be removed even when the dust collecting device is attached to or removed from the cleaner body.

  An embodiment of the present invention will be described using a self-propelled cleaner as an example. Needless to say, the present invention is not limited to a self-propelled cleaner, that is, a robot cleaner, and is also applicable to an electric vacuum cleaner that performs cleaning by a normal artificial operation.

  First, the configuration of the vacuum cleaner of the present invention will be described with reference to FIGS. 1 to 3.

  A cleaning robot (hereinafter referred to as a vacuum cleaner) 1 that is a self-propelled cleaner has a circular main body housing 2 that is self-propelled by driving a driving wheel 29 (both see FIG. 2) by a battery 14. ing. A lid 3 that opens and closes when the dust collector 30 (see FIG. 2) is taken in and out is provided on the upper surface of the main body housing 2.

  FIG. 2 shows a side sectional view of the cleaner 1. A pair of drive wheels 29 projecting from the bottom surface is disposed on the main body housing 2. The rotation axis of the drive wheel 29 is disposed on the center line C of the main body housing 2. When both wheels of the drive wheel 29 rotate in the same direction, the main body housing 2 moves forward and backward, and when both wheels rotate in opposite directions, the main body housing 2 rotates around the center line C.

  A suction port 6 is provided on the lower surface of the front portion of the main body housing 2 that is forward in the movement direction when cleaning is performed. The suction port 6 is formed so as to face the floor surface F by an open surface of a recess 8 that is recessed in the bottom surface of the main body housing 2. A rotating brush (main brush) 9 that rotates on a horizontal rotating shaft is disposed in the recess 8, and a side brush 10 that rotates on a substantially vertical rotating shaft is disposed on both sides of the recess 8.

  A roller-shaped front wheel 27 is provided in front of the recess 8. A rear wheel 26 composed of a free wheel is provided at the rear end of the main body housing 2. As will be described later, the weight of the main body housing 2 is distributed in the front-rear direction with respect to the driving wheel 29 disposed in the center, the front wheel 27 is separated from the floor surface F, and the rotary brush 9, the driving wheel 29 and the rear wheel 26 are floor. Cleaning is performed by contacting the surface F. The front wheel 27 is in contact with a step appearing on the course so that the main body housing 2 can easily get over the step.

  A charging terminal 4 for charging the battery 14 is provided at the rear end of the peripheral surface of the main body housing 2. The main body casing 2 is self-propelled and returns to the charging stand 40 installed indoors, and the charging terminal 4 contacts the terminal portion 41 provided on the charging stand 40 to charge the battery 14. The charging stand 40 connected to the commercial power supply is usually installed along the side wall S in the room.

  A dust collector 30 that collects dust is disposed in the main body housing 2. The dust collecting device 30 is housed in a dust collecting chamber 39 provided in the main body housing 2. The dust collection chamber 39 forms an isolation chamber whose four peripheral surfaces and bottom are covered, and each wall surface except the front wall is closed. A first intake passage 11 that communicates with the recess 8 and a second intake passage 12 that is disposed above the recess 8 and communicates with the motor unit 20 are led out to the front wall of the dust collection chamber 39.

  The dust collector 30 is disposed on the center line C of the main body housing 2 and can be opened and removed by opening the lid portion 3 of the main body housing 2 as shown in FIG. In the dust collector 30, an upper cover 32 that holds a filter unit 33 is attached to the upper surface of a bottomed cylindrical dust collecting container 31. The upper cover 32 is locked to the dust collecting container 31 by a movable locking mechanism 32A, and can be rotated with respect to the dust collecting container 31 by operation of the locking mechanism 32A. Thereby, the dust accumulated in the dust collecting container 31 can be discarded.

  An inflow path 34 that leads to the first intake path 11 by opening an inflow port 34 a at the tip is led out on the peripheral surface (one side surface) of the dust collecting container 31. An inflow portion 34 b is provided in the dust collection container 31 so as to lead the airflow downward by bending continuously from the inflow passage 34. On the peripheral surface of the upper cover 32 (a side surface on the same side as the one side surface of the dust collecting container 31), an outflow passage 35 that opens to the front end and communicates with the second intake passage 12 is led out.

  A packing (not shown) that is in close contact with the front wall of the dust collection chamber 39 is provided around the inflow port 34a and the outflow port 35a. Thereby, the inside of the dust collecting chamber 39 in which the dust collecting device 30 is accommodated is sealed. The front wall of the dust collecting chamber 39 is formed on an inclined surface, and the deterioration of the packing due to sliding when the dust collecting device 30 is taken in and out can be prevented.

  A control board 15 is disposed in the upper part of the main body housing 2 behind the dust collection chamber 39. The control board 15 is provided with a control circuit for controlling each part of the cleaning robot 1. A detachable battery 14 is disposed in the lower part of the rear of the dust collection chamber 39. The battery 14 is charged from the charging stand 40 via the charging terminal 4 and supplies power to the control board 15, the drive wheel 29, the rotating brush 9, the side brush 10, the electric blower 22, and the like.

  A motor unit 20 is disposed at the front of the main body housing 2. The motor unit 20 includes a housing 21 of a resin molded product and an electric blower 22 accommodated in the housing 21. The electric blower 22 is formed by a turbo fan covered with a motor case.

  The electric blower 22 sucks through the second intake passage 12 of the dust collector 30 and exhausts it through the exhaust port 7 (see FIG. 2) provided on the upper surface of the main body housing 2. As a result, air containing dust is sucked from the suction port 6, and exhausted from the exhaust port 7 through the first intake path 11, the dust collector 30, and the second intake path 12. In this path, dust is collected in the dust collecting container 31 by the dust collecting device 30, fine dust is collected by the filter 33, and clean air is exhausted from the exhaust port 7.

  As described above, the air flow path including the electric blower 22 is concentrated in front of the dust collecting chamber 39 and disposed in the front portion of the main body housing 2. For this reason, the control board 15 and the battery 14 are gathered behind the dust collection chamber 39 and arranged at the rear part of the main body casing 2, so that the size of the main body casing 2 can be reduced by reducing wiring and the like. Moreover, since the flow path of the airflow is separated from the control board 15, it is possible to reduce the adhesion of dust to the control board 15 when the airflow leaks and reduce the failure of the control circuit.

  In addition, since the heavy electric blower 22 and the battery 14 are arranged in the front and rear of the main body housing 2, the weight is distributed in a balanced manner in the front and rear direction of the main body housing 2. For this reason, when the rotating brush 9, the driving wheel 29 and the rear wheel 26 are grounded, the main body housing 2 moves forward and backward, and when the rotating brush 9 or the rear wheel 26 is removed from the ground surface due to stairs or the like, the main body housing 2 is dropped. Can be prevented.

  At this time, since the dust collector 30 is arranged on the center line C, the weight balance of the main body housing 2 can be maintained even if the weight of the dust collector 30 changes due to dust collection and disposal. In addition, since the weight of the electric blower 22 is large, a better weight balance can be achieved by disposing the control board 15 and the battery 14 at the rear part of the main body housing 2.

  In the cleaner 1 having the above configuration, when the cleaning operation is instructed, the electric blower 22, the drive wheel 29, the rotating brush 9, and the side brush 10 are driven. As a result, the main body 2 has the rotating brush 9, the drive wheel 29 and the rear wheel 26 in contact with the floor surface F to self-propelled within a predetermined range, and an air flow including dust on the floor surface F is sucked from the suction port 6. . At this time, the dust on the floor surface F is scraped up by the rotation of the rotating brush 9 and guided into the recess 8. Further, the dust on the side of the suction port 6 is guided to the suction port 6 by the rotation of the side brush 10.

  The airflow sucked from the suction port 6 flows rearward through the first intake passage 11 as indicated by an arrow A1, and flows into the dust collector 30 through the inflow port 34a. The airflow flowing into the dust collector 30 collects dust by the filter 33 and flows out of the dust collector 30 through the outlet 35a. Thereby, dust is collected and accumulated in the dust collecting container 31. The airflow flowing out from the dust collector 30 flows forward through the second intake passage 12 as indicated by an arrow A2, and flows into the electric blower 22 of the motor unit 20 through an opening (not shown).

  The airflow that has passed through the electric blower 22 is exhausted from the exhaust port 7 provided on the upper surface of the main body housing 2 in an oblique direction toward the upper rear as indicated by an arrow A3. Thereby, the room is cleaned. At this time, if an ion generator or the like is provided in the air passage path of the motor unit 20, ions generated by the ion generator are exhausted together with clean air from the exhaust port 7 of the main body housing 2 that is self-propelled. Ions contained in the air are distributed throughout the room to be sterilized and deodorized in the room. At this time, since the air is exhausted upward from the exhaust port 7, it is possible to prevent the dust on the floor surface F from being rolled up and improve the cleanliness of the room.

  Further, when both wheels of the drive wheel 29 are rotated in opposite directions, the main body housing 2 rotates around the center line C and changes its direction. Thereby, while making the main body housing | casing 2 self-propelled to the whole desired range, an obstacle can be avoided and self-propelled. Note that the main body housing 2 may be moved backward by reversing both wheels of the drive wheel 29 with respect to forward movement.

  When the cleaning is completed, the main body housing 2 self-propels and returns to the charging stand 40. Thereby, the charging terminal 4 contacts the terminal part 41 and the battery 14 is charged.

  In addition, the electric blower 22 and the ion generator can be driven while the battery 14 is being charged or after the charging is completed in the feedback state of the main body housing 2 depending on the setting. As a result, an airflow containing ions is sent from the exhaust port 7 upward and rearward. Since the charging terminal 4 is provided at the rear end of the main body housing 2, the airflow including ions flows in the direction of the charging base 40 and rises along the side wall S. The airflow circulates along the indoor ceiling wall and the opposite side wall. Accordingly, the ions are spread throughout the room, and the sterilizing effect and the deodorizing effect can be improved.

  According to this embodiment, since it exhausts upwards from the exhaust port 7 provided in the upper surface of the main body housing | casing 2, it can prevent raising of the dust of the floor surface F, and can improve indoor cleanliness.

  Further, since the exhaust port 7 is disposed at the front of the main body housing 2 and exhausted obliquely rearward from the exhaust port 7, the exhaust airflow flows away from the floor F at the rear end of the main body housing 2. Accordingly, it is possible to reliably prevent the dust on the floor surface F from being rolled up.

(Configuration of the dust collector of the present invention)
Then, the structure of the dust collector of this invention is demonstrated in detail.

  The dust collector 30 of the present invention has a dust collection container 31 for collecting dust. The dust collecting container 31 has an opening 31d (see FIGS. 6, 7, and 8) whose upper part is opened, and a filter unit is formed on the upper part so as to cover the opening 31d as shown in FIG. 5B. 33.

  The dust collecting container 31 is provided with an openable and closable upper cover 32 whose one end is pivotally supported so as to cover the opening 31 d including the filter unit 33. The upper cover 32 is provided with the filter unit 33 that is separable from the upper cover and is usually housed in the cover and held in a press-fit state.

  As shown in FIG. 7, the dust collection container 31 has an inlet 31 a that is in communication with the suction port 6 of the cleaner body on one side surface. The inflow port 31 a is formed in the vicinity of (adjacent to) the filter unit 33.

  An inflow path 34 that forms a first intake path 11 that guides air from the suction port 6 to the dust collection container 31 is connected to the inflow port 31 a, and the inflow path 34 projects from the dust collection container 31. Are integrally formed. The inflow channel 34 is provided in an upwardly inclined state.

  On the other hand, the upper cover 32 is provided with a rotatable handle 36. The handle 36 is formed with a hole 36a (see FIG. 8) for pivotal support at both ends serving as free ends. The hole 36 a is inserted with a protruding shaft portion 32 g provided on the upper cover 32 side, so that the handle 36 can be rotated with respect to the upper cover 32.

  The upper cover 32 forms a handle storage portion 32a (see FIG. 6B and the like) in which a part of the periphery of the upper surface on the opposite side where the inflow passage 34 is provided is recessed. The storage portion 32a is formed in a form in which the handle 36 is stored and the upper surface is flush with the storage state. In addition, the storage portion 32a of the upper cover 32 is formed with a concave portion 32b through which the handle 36 can be picked out in order to facilitate removal of the stored handle 36 from the storage portion 32a.

  Therefore, in a state where the dust collector 30 is attached to the main body of the vacuum cleaner 1, the handle 36 can be taken out from the storage portion 32a and can be rotated upward. In this state, the handle 36 is held, and the dust collector 30 can be easily taken out from the main body of the vacuum cleaner.

  A support structure is provided to allow the dust collection container 31 to be opened with respect to the upper cover 32, that is, to be rotatable. Before explaining this configuration, a mechanism for restricting the rotating state, that is, a locking mechanism 32A for restricting opening and closing of the dust collecting container 31 with respect to the upper cover 32 will be described. This is a locking mechanism for locking the dust collecting container 31 to the upper cover 32 in order to make the dust collecting device 30 shown in FIG.

  If the lock mechanism 32A is described with reference to FIG. 5, the lock operation portion 32e having the lock claw 32d provided on the upper cover 32 side, and the protrusion provided on the dust collecting container 31 side to hook the lock claw 32d. 31b. The locking operation part 32e is pivotally supported on the cover 32 side so as to be rotatable, and is biased in a direction in which the locking claw 32d is locked to the protrusion 31b by a biasing force (not shown), for example, a coil-shaped compression spring. .

  Further, as shown in FIG. 7, a recess 32c is formed on the side of the cover 32 corresponding to the side opposite to the locking claw 32d in order to rotate in a direction against the urging force of the locking operation portion 32e. Yes. Therefore, in FIG. 7 and the like, when the locking portion 32e is pressed counterclockwise, the locking claw 32d on the side opposite to the pressing portion is separated from the protrusion 31b, and the locked state is released. As a result, the dust container 31 is opened with respect to the cover 32.

  Here, the locking mechanism 32A is provided with a locking operation portion 32e in a recess 32c in which the central portion of the upper cover 32 is recessed. Correspondingly, the portion corresponding to the protrusion 31b is also recessed in the dust container 31 side, and the protrusion 31b is provided in the recess. As a result, the locking mechanism 32 </ b> A itself does not protrude from the dust collector 30. Therefore, the locking mechanism 32A cannot be operated in a state where the dust collecting device 30 is mounted in the dust collecting chamber 39 of the main body of the cleaner 1. The dust collection chamber 39 on the main body side of the vacuum cleaner 1 can be formed in a simple shape having a flat surface shape. As a result, it is not necessary to configure the shape according to the locking mechanism 32A, and the dust collection chamber 39 can be formed in a simple shape.

  On the other hand, the filter unit 33 is detachably attached to the upper cover 32. As shown in FIG. 7, a space 50 is formed between the upper surface of the filter unit 33 and the lower surface of the upper cover 32, and the space 50 becomes an exhaust space. The purified air ventilated through the filter unit 33 passes through the exhaust space 50 and is exhausted from the dust collector 30 through the exhaust port 7 of the cleaner 1 body.

  The air that passes through the filter unit 33 is introduced into the outflow passage 35 that communicates with the second intake passage 12 serving as an exhaust passage on the cleaner body side. Therefore, the outflow path 35 is integrally formed on the side surface of the upper cover 32, that is, on the same surface side as the inflow path 34 side of the dust collecting container 31.

  Further, as shown in FIG. 4, a support shaft 35 b protruding from both ends in the longitudinal direction is integrally formed in the outflow passage 35 of the upper cover 32. A boss portion 31c formed integrally with the dust collecting container 31 is pivotally supported on the support shaft 35b. The boss 31c protrudes from the side surface of the dust collecting container 31 and has a support hole into which the support shaft 35b is inserted. By inserting the support shaft 35 b into the support hole, the dust collecting container 31 can be opened and closed (rotatable) with respect to the upper cover 32. The support shaft 35b is formed so as to protrude from the side surface of the outflow passage 35, but may be provided on the upper cover 32 side.

  A coil spring 37 is inserted into one side of the support shaft 35b. One end of the coil spring 37 is engaged with the upper cover 32 and the other end is engaged with the boss 31c side of the dust collecting container 31. Has been. Thereby, when the dust collecting container 31 is opened, it is greatly opened by the biasing force of the spring 37 (see FIGS. 6B, 7B, and 8). If this opening is an opening due to the weight of the dust collecting container 31, it is 90 degrees or less, and the dust collected in the dust collecting container 31 cannot be disposed of reliably. In order to ensure that the opening angle exceeds 90 degrees, a spring 37 is provided so that the opening 31a of the dust collecting container 31 faces the lower surface, and the collected dust is surely discarded. Yes.

  Next, the configuration of the filter unit 33 according to the present invention and a dust removal mechanism for removing dust from the filter will be described.

(Filter configuration)
As described above, the filter unit 33 is attached to the upper cover 32, that is, provided in a state of being accommodated and held.

  The filter unit 33 of the present invention includes a filter 33a (shown in FIG. 5B, etc.) body formed in a pleat shape for allowing air to pass through and collecting dust, and a resin surrounding the entire circumference of the filter 33a body. And a frame 33b made of the like. A packing member 33c made of rubber or the like is attached to the entire circumference of the peripheral surface of the frame 33b in order to prevent air leakage and the like. The lower surface of the packing member 33 c comes into contact with the opening edge of the opening 31 d of the dust collecting container 31. Therefore, the filter unit 33 covers the opening 31d of the dust collection container 31, prevents air leakage from the opening 31d, and seals the inside of the dust collection container 31.

  In FIG. 5B, the filter 33a is resin-processed so that the pleated peak (the peak on the exhaust side) does not break the filter due to contact with a contact part described later. The portion of the valley between the mountains is not processed with resin.

  Further, the packing member 33 c is press-fitted in a state of being in close contact with the inner peripheral surface of the upper cover 32. The filter unit 33 is held in the upper cover 32 in a press-fitted state by the press-fitting. Thus, the sealed state of the exhaust space 50 after passing through the filter is secured.

  Since the filter unit 33 is held by the upper cover 32, if the upper cover 32 rotates with respect to the dust collection container 31, the filter unit 33 is rotated in accordance with the rotation and opens the opening 31 d of the dust collection container 31. become. If filter dust removal is performed in this state, the attached dust is scattered and the meaning of dust removal is lost.

  In order to solve this problem, it is necessary to separate the filter unit 33 from the upper cover 32 and place the filter unit 33 so as to cover the opening 31d of the dust collecting container 31. As an example of a configuration for that purpose, a support portion (boss portion) 33 d that protrudes from the same surface side as the inflow passage 34 side of the dust collecting container 31 is integrally formed on the frame 33 b of the filter unit 33.

  The support portion 33d is supported coaxially with a support shaft 35b provided on the upper cover 32. Therefore, the support portion 33d is integrally formed with a hemispherical protrusion inserted from the end opposite to the through hole of the boss portion 31c of the dust collecting container 31 into which the support shaft 35b is inserted. The support portion 33d closes the through hole of the boss portion 33c of the dust collecting container 31, and is supported to be rotatable with respect to the through hole. As a result, the filter unit 33 is rotated together with the upper cover 32 while being held on the upper cover 32 side, and there is no fear of the holding state being lost, and the filter unit 33 can be rotated with respect to the dust collecting container 31. Become. Therefore, the operation of discarding the dust collected in the dust collecting container 31 is not affected at all.

  In the present invention, in order to remove dust adhering to the filter, it is necessary to separate the filter unit 33 from the upper cover 32 and to place the separated filter unit 33 so as to cover the opening 31d of the dust collecting container 31. is there. However, the filter unit 33 is in a state of being held by the upper cover 32, and when the upper cover 32 is opened, the filter surface to which dust is attached is exposed. Since the user removes the exposed filter unit 33 by hand, the maintenance is not excellent and the user is not friendly. In other words, the working hand is also soiled with dust.

  Therefore, in the present invention, as shown in FIGS. 5 and 9, a convex portion 33 e is provided on a part of the packing member 33 c of the filter unit 33 on the side opposite to the support shaft for opening and closing. The convex portion 33e is formed with a notch 32f at a corresponding portion of the upper cover 32 so as to be exposed even when the upper cover 32 is closed. The exposed surface of the convex portion 33e is subjected to a bumping process (drawing process) as an anti-slip process. Such processing may be knurling or the like.

  In the above configuration, as shown in FIG. 5, with the upper cover 32 closed by the dust collecting container 31, the filter unit 33 is pressed by pressing the convex portion 33e, releasing the locking mechanism 32A, and opening the upper cover 32. The upper cover 32 is opened upward in a state where the dust collecting container 31 holds the 33 (see FIG. 5B). Therefore, the user does not touch the collection surface of the filter unit 33, and the non-collection surface is exposed to the outside while the filter unit 33 is held in the dust collecting container 31 (see FIG. 5B). Accordingly, the non-collecting surface (exhaust surface side) is exposed to the outside while the filter unit 33 is held in the dust collecting container 31 without the user touching the collecting surface of the filter unit 33. Therefore, the filter unit 33 can be vibrated by sliding the peak portion of the filter on the non-collecting surface with a rod or the like, and the dust collected on the collecting surface can be removed. In this case, since the opening 31d is closed by the packing member 33c, the filter unit 33 can prevent the dust that has been removed from being scattered.

  As described above, the dust removal of the filter 33 a can be performed even when the upper cover 32 is separated from the filter unit 33. In addition, in the dust removal operation, there is no worry that the hands and the like are stained with dust.

  The filter unit 33 can be separated as a separate member from the dust collecting container 31 and the cover 32 through the support portion 33d as a unit. Therefore, the filter unit 33 can be easily replaced. In this replacement, if the protruding support portion 33d is integrally formed with the filter frame 33b with resin or the like, it can be easily removed from the boss portion 31c by using the elasticity and elasticity of the resin and by pushing and deforming both sides. Can do. On the contrary, when attaching the new filter unit 33, the filter unit 33 can be easily pivoted by being fitted into the through hole of the boss portion 31c while the support portion 33d is pushed open.

(Dust removal mechanism provided in the dust collector of the present invention)
The above is an example of the configuration of the filter of the present invention, and the dust removal mechanism provided in the dust collector 30 of the present invention for efficiently removing dust attached to the filter will be described in detail below.

  This dust removal mechanism is provided in the dust collector 30. 9 and 10 show a first embodiment of the dust removal mechanism 51. In particular, FIG. 9 shows a plan view viewed from the top with the top cover 32 removed. FIG. 10 is a side view showing the dust removing mechanism 51 according to the present invention in a partial cross section. 9 and 10 show the filter unit 33 in a simplified rectangular shape so that the dust removal mechanism 51 of the present invention can be easily understood. Further, the support portion 33d is also shown in an omitted state. The filter unit 33 is press-fitted and held in the upper cover 32 and can be separated from the upper cover 32.

  The dust removing mechanism 51 according to the first embodiment of the present invention includes a first moving unit 52A and a second moving unit 52B for vibrating the filter main body of the filter unit 33, and a manual operation related to the moving operation of the both moving units 52. The operation unit 53 includes a first interlocking unit 54A and a second interlocking unit 54B for moving the first moving unit 52A and the second moving unit 52B in opposite directions in conjunction with an operation by the operating unit 53. The

  The first and second moving parts 52A and 52B are provided to be movable in parallel. The first moving part 52A has a first support (two slide bars, a shaft, etc.) 55A that supports the moving part 52A so as to be movable. Moreover, it has the 2nd support body 55B which supports the 2nd moving part 52B so that a movement is possible. The first and second supports 55A and 55B are arranged in parallel, and both end portions thereof are attached to the side plate portion of the upper cover 32. Accordingly, the first and second moving portions 52A and 52B are provided so as to be movable (slidable) in the arrangement direction of the support 55 (left and right in the drawing) with respect to the first and second supports 55A and 55B. ing.

  Although detailed description will be given later, when the first moving unit 52A moves from left to right in FIG. 9, the second moving unit 52B moves (slides) from right to left. It is configured. About this movement, it becomes clear by explaining the structure of a connection part.

  Vibrating members 60A and 60B for vibrating the filter extended to the filter 33a side of the filter unit 33 are integrally or separately attached to the first and second moving parts 52A and 52B. . The vibration members 60A and 60B are provided on both sides in the width direction (direction perpendicular to the slide direction) of the moving parts 52A and 52B. The vibration members 60A and 60B are provided with contact portions 61 and 62 that extend to the filter 33a and come into contact with the filter, respectively. As shown in FIG. 10, a plurality (four in the sliding direction) of contact portions 61a and 61b are provided on the front side and the back side of the vibration member 60A, respectively. Also in the vibration member 60B, a plurality of contact portions 62a and 62b are provided on the front side and the back side, respectively.

  One contact portion (front side) 61a provided in a plurality in the sliding direction in the vibration member 60A extends so as to contact the crest 33A of the filter 33a, and is provided so that the contact timing is gradually shifted. . Further, the other contact portion (back side) 61b is also provided so that the contact timing is shifted. Further, the contact timings of both contact portions 61a and 61b are provided to be shifted. With such a configuration, one of the contact portions 61a or 61b on one side comes into contact with one of the peaks 33A of the filter 33a.

  Note that the contact timings of the contact portions 61a on the near side may be all the same, and may be shifted with respect to the contact timing of the contact portion 61b on the back side.

  In addition, if the front and back side contact portions 61a and 61b are in contact with each other at the same time (even if they are slightly out of contact), and the positions of the contacting peaks are all different between the front side and the back side, dust removal Efficiency can be increased.

  About the timing which contacts above, it can be made to contact with a filter by a suitable aspect by considering the space | interval etc. which each contact part provides.

  As described above, at the same time as the configuration of the contact portion of the vibration member 60A, the contact portions 62a and 62b provided on the vibration member 60B on the other moving portion 52B side are also contacted at different timings as in the vibration portions 61a and 61b. It is only necessary to allow the filter 33a to vibrate efficiently in consideration of the respective combinations and the like.

  Furthermore, although the two vibration members 60 are provided on both sides of the two moving parts 52, three vibration members may be provided in parallel by extending from the central part of the moving part 52. Also in this case, it is more effective to shift the contact timing of each contact portion. Instead of three, more contact members may be provided.

  In the above description, the vibration member 60 is described as being provided as a separate member from the moving unit 52. The contact portions 61 and 62 of the vibration member 60 may be formed integrally with the moving portion 52. Therefore, the moving part 52 acts as a vibration member.

  In addition, in FIG. 9, the example which arrange | positions the vibration member 60 in the form which can cover the whole region of the filter 33a about both the moving parts 52 was shown. This is made possible by providing at least two upper and lower moving parts 52 in FIG. Thereby, the dust adhering to the whole area of the filter 33a can be efficiently removed.

  The above is an example of the configuration of the moving unit 52 including the vibrating member 60. Next, the structure of the operation part 53 and the connection part 54 is demonstrated.

  If the example of the operation part 53 is demonstrated with reference to FIG. 10, the rotating shaft 53a provided rotatably with respect to the top | upper surface of the upper cover 32, and the upper end part of the rotating shaft 53a are rotatably supported. And a knob 53b. The rotation shaft 53a is rotatably supported by a bearing portion 56 attached to the upper cover 32.

  The connecting portion 54 for moving the moving portions 52 in the opposite directions in conjunction with the operation of the operating portion 53 is a rotating plate 54a fixed to the lower end of the rotating shaft 53a of the operating portion 53, the rotation Two connecting pins 54b and 54d, which are rotatable on the lower surface of the plate 54a and displaced by 180 ° around the fixed rotation shaft 53a, and two connections fixed to the upper surfaces of both the moving bodies 52A and 52B. It is comprised with the bodies 54c and 54e.

  Although the rotating plate 54a is illustrated in a disk shape in FIG. 10, the rotating plate 54a is not limited to such a shape, and may be a plate-shaped plate material extending in the 180 ° radial direction at least about the rotation shaft 53a. . However, it can be expected to rotate in a well-balanced manner during operation by using a disk shape.

  Further, the coupling bodies 54c and 54d are formed in a U-shaped cross section having a rectangular shape in plan view and a central portion in the longitudinal direction serving as a concave portion. The coupling bodies 54c and 54d are fixed on the first and second moving parts 52A and 52B so that the recesses are in the upper position and the groove direction of the recesses is substantially perpendicular to the sliding direction. ing. One connecting pin 54b is inserted into the recess of the one connecting body 54c, and the other connecting pin 54e is inserted into the recess of the other connecting body 54d.

  As described above, the connecting portion 54 includes the common rotating plate 54a, the one connecting pin 54b, the first connecting portion 54A having the connecting portion 54c, the common rotating plate 54a, the other connecting pin 54d, and the connecting portion. It consists of the 2nd connection part 54B which has 54e.

  The knob 53b is normally held in a state where it is tilted to the lower surface from the upper end portion of the rotating shaft 53a, and is rotatably provided so as to protrude from the upper end portion of the rotating shaft 53a as shown in FIG. Yes. Therefore, in a state where the dust collector 30 is mounted on the cleaner body, the knob 53b is tilted and does not get in the way. Then, the lid 3 of the main body of the vacuum cleaner 1 is removed (opened), and the dust removal operation can be performed by projecting the knob 53b as shown in FIG.

(Dust removal operation of the dust removal mechanism of the present invention)
Next, the dust removal operation of the dust removal mechanism 51 according to the configuration of the present invention will be described. In order to perform filter dust removal, the lid 3 of the cleaner 1 main body is opened, and the dust collector 30 can be taken out from the cleaner 1 main body with the handle 36 of the dust collector 30. Further, the dust removal operation can be performed even when the dust collecting device 30 is housed.

  Therefore, the knob 53b of the operation unit 53 is set to the operating state, and the knob 53b is rotated in either direction. This rotation is transmitted to the first and second moving parts 52A and 52B via the first and second connecting parts 54A and 54B. That is, when the rotating plate 54a is rotated, the connecting pins 54b and 54d on the lower surface thereof are rotated at positions away from the center position of the rotating shaft 53a in the radial direction. By this rotation, the connecting pins 54b and 54d move so as to slide up and down in the recesses of the connecting bodies 54c and 54e.

  For example, when the operation unit 53 is rotated counterclockwise (counterclockwise) in the state shown in FIG. 9, the connection pin 54b is rotated around the rotation shaft 53a, and the rotation is performed from the left to the right at the connection body 54c. The first movement unit 52A is moved in that direction. On the contrary, when the connecting pin 54d is rotated counterclockwise about the rotation shaft 53a, the rotation is converted into the movement from the right to the left by the connecting body 54e. The moving part 52B is moved in that direction.

  As described above, the first and second moving units 52A and 52B are moved in opposite directions by rotating the operation unit 53 in one direction. Due to this movement, the contact portions 61a and 61b and the contact portions 62a and 62b come into contact with the filter 33a from opposite directions via the vibrating members 60A and 60B provided in the first and second moving portions 52A and 52B. Then, the filter 33a is vibrated. Due to the vibration, dust collected and adhered to the filter 33 a is removed and shaken off to the dust collecting container 31.

  Moreover, since the contact part 61 and the contact part 62 are made to contact and vibrate from the mutually opposite direction with respect to the filter 33a, the vibration effect is promoted and the dust removal effect is improved. In addition, since the timing of contact is shifted in each case, the vibration effect is further promoted, and the dust removal efficiency is further promoted.

  For example, the operation unit 53 is rotated 180 degrees in the opposite direction after being rotated 180 degrees, for example. By this operation, it moves in the opposite direction from the past, and the dust removal operation is performed. The dust removal effect as described above can be expected.

  According to this embodiment, the operation unit 53 may be provided with a rotation restricting portion so that rotation of 180 ° or more can be restricted. The rotation operation direction may be reversed within the restricted range. The restricting portion can be configured such that the rotation shaft 53a does not rotate 180 ° or more.

  The moving distance of both the moving parts 52 is substantially equal to twice the distance between the rotating shaft 53a and the connecting pin 54b or 54d (a little less than twice). Therefore, the contact portion 61 or 62 comes into contact with the crest portion 33A of the filter 33a at each timing, and vibrates the filter unit 33, particularly the filter 33a. By the vibration caused by this movement, the collected dust can be effectively removed and dropped to the dust collecting container 31 side.

  Further, if each contact portion 61 or 62 is brought into contact with a deviated timing, the load spent on the rotating operation due to contact with each other at the same time is greatly reduced, and the dust removal effect is improved at the same time as the dust removal operation. Can greatly reduce the burden on the user.

  At the time of one movement when the two moving parts 52 make one reciprocation, the plurality of contact parts 61 or 62 of the vibrating member 60 come into contact with the entire length of the filter in the sliding (moving) direction and vibrate so as to vibrate. The length in the slide direction is set. That is, the interval between the contact portions and the length of the moving portion 52 (or the vibration member 60) are appropriately set so that all of the peaks 33A of the filter 33a come into contact with the contact portion 61 or 62 of the vibration member 60.

  In addition, the dust removal mechanism 51 mentioned above was demonstrated by providing in the dust collector 30. FIG. In this case, the dust removing mechanism 51 is provided on the upper part of the filter unit 33, and at least the knob 53 b of the operation unit 53 is provided so as to be located outside the upper cover 32. For this reason, when the lid 3 is opened in a state where the dust collecting device 30 is mounted in the dust collecting chamber 39 of the main body of the vacuum cleaner 1, dust removal work can be performed. Moreover, even if the dust collecting device 30 is taken out from the dust collecting chamber 39 of the vacuum cleaner 1, the dust removing operation can be performed. Here, as described above, the knob 53b of the operation unit 53 is not shown in FIG. 4, for example, to facilitate understanding of the configuration of the present invention, but as shown in FIG. It is provided in a state exposed on the upper surface.

  According to the dust removal mechanism 51 of the present invention, the dust collected and adhered to the filter 33a is removed after the dust removal operation (operation) as described above, and the dust removed is collected in the dust collection container 31. Dust is collected together. In order to discard the collected dust, the upper cover 32 may be separated (rotated) from the dust collection container 31. Therefore, the locking mechanism 32A is operated to lock the upper cover 32 and the dust collecting container 31, and the locking claw 32d is released. As a result, the dust collecting container 31 is rotated about the support portion as shown in FIG. 8, and is opened so that the opening 31d faces downward by the action of the spring 37, so that the dust in the dust collecting container 31 is surely removed. Can be discarded. At this time, since the filter unit 33 is held by the upper cover 32, the filter unit 33 can be discarded without bringing a hand or the like into contact with the collection surface of the filter.

  On the other hand, the filter unit 33 is held by the upper cover 32, but can be separated from the upper cover 32 and replaced. In this case, the upper cover 32 is rotated in a state where the protruding portion 33e exposed from the notch 32f of the upper cover 32 of the filter unit 33 is pressed, so that the press-fitted state via the packing member 33c is solved. The filter unit 33 is placed in a state of covering the opening of the dust collecting container 31 (see FIG. 5B). In this state, the rotation support state can be solved by opening the support portion 33d outward. Then, the knob 33e of the filter unit 33 is held, the old filter unit 33 is discarded, and replacement with a new filter unit is possible.

  In this case, since the dust removal mechanism 51 is provided on the upper cover 32 side, the replacement of the filter unit 33 is not hindered at all. Further, the dust removal mechanism 51 is not damaged or damaged.

(Second embodiment of the dust removing mechanism of the present invention)
According to the dust removing mechanism 51 described above, if the first and second moving parts 52A and 52B are moved in opposite directions to each other, and the operating part 53 is rotated by 180 ° to reciprocate them, the opposite direction is obtained. Will be rotated. According to the configuration of the first embodiment, the rotating plate 54a that constitutes the connecting portion that is rotated by the operation of the operating portion 53 is shared by the first and second connecting portions 54A and 54B. It is also for the purpose.

  In view of this, in the second embodiment, a configuration will be described in which rotation is always performed in one direction, so that each moving unit is reciprocated once in the opposite directions and is repeatedly executed. For this purpose, the rotating plate is not used as a common member, but is configured as a separate member. In addition, an interlocking mechanism is provided to move both moving bodies 52A and 52B. According to the first embodiment, the interlocking mechanism is also used by the rotating plate 54a.

  As described above, if the rotating plate is configured as a separate member, that is, a separate member, when the rotating plate is rotated 360 ° by a rotating operation in one direction, both moving parts can be reciprocated once and can move in opposite directions. Details of the configuration will be described with reference to FIGS. 11 and 12. FIG.

  Hereinafter, the same members and members having the same function and function described in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. The configuration greatly different from the previous embodiment is such that the first rotating plate 540a and the second rotating plate 540b are rotatably provided on the top plate of the upper cover 32 without using the rotating plate constituting the connecting portion 54 in common.

  The rotation shaft 53a of the operation unit 53 described above is fixed to the first rotation plate 540a. Therefore, the first rotating plate 540a is integrally rotated in the rotation operation direction of the operation unit 53. The first rotating plate 540a is provided with the connecting pin 54b described above, and constitutes a first connecting portion 54A including a connecting body 54c having a recess through which the connecting pin 54b is inserted.

  The second rotating plate 540b is fixed to a rotating shaft 53c that is rotatably supported by a bearing 57 provided on the upper cover 32. The second rotating plate 540b is provided with the connecting pin 54d described above, and constitutes a second connecting portion 54B including a connecting body 54e having a recess through which the connecting pin 54d is inserted.

  The first rotating plate 540a and the second rotating plate 540b are provided with rotating pulleys 541 and 542 for simultaneously rotating both in the same direction. A belt 543 is stretched between the rotary pulleys 541 and 542 in order to rotate the first and second rotary plates 540a and 540b in synchronization. An interlocking mechanism is configured including the belt 543 and the rotating pulleys 541 and 542.

  With the above configuration, when the operation unit 53 is rotated in any direction, for example, in the left direction (counterclockwise direction) in FIG. 11, the rotating plate 540a rotates in that direction. Due to this rotation, the first moving part 52A is moved from the left to the right in the first connecting part 54A. By the movement of the first moving part 52A, the contact parts 61a and 61b of the vibration member 60A come into contact with the filter 33a, and the filter 33a is vibrated.

  On the other hand, the rotating plate 540b of the second connecting portion 54B is rotated in the same direction as the rotating plate 540a of the first connecting portion 54A via the belt 543 by the interlocking mechanism. By this rotation, the second moving portion 52B is moved from the right to the left at the second connecting portion 54B. Due to the movement of the second moving part 52B, the contact parts 62b and 62b of the vibration member 60B come into contact with the filter 33a and vibrate the filter 33a.

  If the operation unit 53 is rotated, for example, by 180 ° or more, the first moving unit 52A is moved from the right end to the left by the first connecting unit 54A after moving to the rightmost end. Conversely, after the second moving part 52B has moved to the leftmost end via the interlocking mechanism, it is moved in the right direction from the left end by the connecting part 54B.

  As described above, by rotating the operation unit 53 in one direction, the first moving unit 52A and the second moving unit 52B move in directions opposite to each other and repeat the reciprocating movement. By this movement, the filter 33a comes into contact with the contact portions 61a, 61b, 62a, 62b of the vibration members 60A, 62B and vibrates. The vibration at this time is also promoted by contact from opposite directions, and the effect of removing dust attached to the filter 33a is enhanced. This dust removal effect is the same as in the first embodiment.

  Moreover, according to the present embodiment, the operation unit 53 can be rotated in either direction, so that the moving units 52A and 52B can reciprocate in the opposite directions. Therefore, the dust removal operation can be performed with a very simple operation.

  As described above, in the dust removing mechanism according to the first embodiment, the first and second moving units 52A and 52B are provided point-symmetrically with the rotation shaft 53a of the operation unit 53 in FIG. In this case, similarly in the connecting portion, the first connecting portion 54A and the second connecting portion 54B are provided in a point-symmetric manner with the rotation shaft 53a as the center point.

  In FIG. 11, the center point of a straight line connecting the rotation shaft 53a of the operation unit 53 serving as the rotation center of the first connection portion 54A and the rotation shaft 53c serving as the rotation axis of the second connection portion 54B, that is, The first and second moving parts 52A and 52B are provided point-symmetrically with the position corresponding to the rotation shaft 53a of the operation part 53 in FIG. 9 as the center point. The first and second connecting portions 54A and 54B are also provided point-symmetrically.

  According to the second embodiment, the first and second connecting portions 54A and 54B are operated in an interlocked manner by the interlocking mechanism. A specific example thereof is an interlocking mechanism including rotating pools 541 and 542 and a belt 543.

  On the other hand, according to the first embodiment, the first and second connecting portions 54A and 54B use the common rotating plate 54a, and the interlocking mechanism for interlocking the connecting portions is as follows. The rotating plate 54a corresponds to the rotating plate 54a, and the rotating plate 54a also serves as an interlocking mechanism.

  Further, the interlocking mechanism is not limited to the rotary pulleys 541 and 542, the belt 543, and the like. For example, in FIG. 11, the rotating plates 540a and 540b can be configured as gears, and an intermediate gear for transmitting rotation can be meshed with each other to form an interlocking mechanism. Thereby, the rotating plates 540a and 540b can be simultaneously rotated in the same direction. Therefore, the first and second moving parts, the first and second connecting parts can be provided point-symmetrically as described above.

  On the other hand, if the rotating plates 540a and 540b are configured as gears and meshed with each other without providing an intermediate gear, both rotating plates rotate in conjunction with the rotating operation of the operation unit 53. In this case, the rotating plate 540a and the rotating plate 540b rotate in directions opposite to each other. Therefore, the moving directions of the first and second moving portions 52A and 52B by the first and second connecting portions are the same direction at a certain rotation angle, but there is also a period of moving in opposite directions. In such a case, a dust removal effect can be expected by moving in the same direction in some periods and moving in the opposite direction in other periods. Moreover, the effect of repeating the movement in the same direction and the movement in the reverse direction in a partial period can be expected.

  For example, even if the belt 543 is stretched by crossing in FIG. 11, the rotating plates 540a and 540b of the first and second connecting portions are rotated in opposite directions. Therefore, the same operation as described above can be realized.

  Here, when the moving directions of the first and second moving portions 52A and 52B are completely reversed by rotating the rotating plate 540a and the rotating plate 540b in the opposite directions, the second connecting portion 54B The position where the connecting pin 54d is provided may be provided as shown in FIG. That is, as shown in FIG. 13, the connecting pin 54d is provided not at a point-symmetrical position with respect to FIG.

  FIG. 13 shows a dust removal mechanism, and is shown with the filter unit 33 omitted. Also, the reference numerals are all the same. In the figure, a rotating plate 540a and a rotating plate 540b are gears that mesh with each other. Connection pins 54b and 54d are provided on the lower surface of the gear.

  As a configuration for rotating the rotating plates 540a and 540b in the reverse direction instead of such a gear configuration, when the rotating pulley is provided as described above, if the belt 543 is configured to be cross-crossed, the directions are opposite to each other. It is rotated.

  According to this configuration, the rotating plate 540a and the rotating plate 540b rotate in opposite directions, but the connected first moving unit 52A and second moving unit 52B are moved in the opposite directions.

The dust collector 30 described above is configured so that the filter unit 33 is also rotatably supported like the upper cover 32. However, the filter unit 33 may be separated from the upper cover 32 when necessary, while being normally held by the upper cover 32.

  Therefore, the support part 33d of the filter unit 33 is eliminated. The filter unit 33 is held in a state where it is press-fitted into the upper cover 32 by a packing member 33c. Even in such a configuration, the dust removal work can be performed by the dust removal mechanism 51, that is, in a state where the upper cover 32 is closed with respect to the dust collection container 31. After the work, when the dust is discarded, the filter unit 33 is also held by the upper cover 32 even if the upper cover 32 is opened, and the collected dust can be reliably discarded as described above.

  For filter replacement, the filter unit 33 can be separated from the upper cover 32 by opening the filter unit 33 to the upper cover 32 in a state where the filter unit 33 is placed on the dust collecting container 31 side. For this operation, as described above, the upper cover 32 may be opened by pressing the convex portion 33e of the filter unit 33 against the container side.

  Further, the upper cover 32 and the dust collecting container 31 are rotatably supported. However, the upper cover 32 may be normally held in the dust collecting container 32 including the filter unit 33, and the two may be provided so as to be separable as required. In order to hold both together, a locking mechanism or the like can be provided, and the locking mechanism can be released to separate the two.

(Other forms of operation unit)
The operation unit 53 for manually operating the dust removal mechanism 51 is not configured by the rotation shaft 53a and the knob 53b as shown in FIG. 10, but may be configured as shown in FIG. Referring to FIG. 14, the operation portion 53 is provided rotatably on the operation lever 53c supported by the shaft 53d on the upper end portion of the rotation shaft 53a and on the opposite side to the shaft support portion of the operation lever 53c. And the selected knob 53e. Therefore, the rotary shaft 53a can be rotated by holding the knob 53e and rotating it in either direction.

  When the rotation operation is not performed, the operation unit 53 can be put into the retracted state by rotating the operation lever 53c in the opposite direction about the shaft 53d (rotation to a position indicated by a broken line). . Therefore, in order to accommodate the protruding knob 53e, a recess 32i is formed in which a part of the top surface of the upper cover 32 is recessed toward the filter side. With such a configuration of the operation unit 53, the rotation operation is simple, and the dust removal effect can be further enhanced.
