The opening / closing member 6 is rotatably attached to an upper end portion of the boundary wall portion 2c of the cleaner body 2 that partitions the housing space S and the rear portion 2a by a hinge shaft 7 (see FIG. 5). As shown in FIGS. 2 and 3, the hinge shaft 7 is concealed by the front side wall 2b in the state where the opening / closing member 6 is closed as shown in FIG. The opening / closing member 6 is positioned at the lower end of the opening / closing member 6 in the opened state. Reference numeral 2 d denotes a bearing portion that supports the hinge shaft 7, and this bearing portion 2 d is provided at the rear portion of the cleaner body 2.

  When the opening / closing member 6 is closed, the front end portion of the opening / closing member 6 is connected to the main body handle 5 via an engagement / disengagement means (not shown). At the same time, the opening / closing member 6 can be manually opened by releasing the connection of the system detaching means by a release knob (not shown) provided on the opening / closing member 6. Accordingly, when the opening / closing member 6 is manually closed, the upper and lower ends of the main body handle 5 are supported, and thus the user can carry the cleaner body 2 while holding the main body handle 5. .

  The opening / closing member 6 has a main body suction port 8 at its distal end. A main body connection end of a flexible dust suction hose (not shown) is detachably connected to the main body suction port 8 in a state where the opening / closing member 6 is closed. An extension pipe (not shown) is connected to the tip of the dust suction hose, and a suction port (not shown) in contact with the surface to be cleaned is connected to the tip of the extension pipe. Therefore, dust is sucked through the suction system including the dust suction hose, the extension pipe, and the suction port body.

  As shown in FIGS. 2 and 3, for example, a dust separation device 11 is detachably disposed in the accommodation space S as dust collecting means. The dust separation device 11 includes an upper cyclone portion 12 that forms an inertia separation portion, a lower dust cup portion 13, a pleat filter 14 for capturing fine dust, and a cup handle 15.

When the opening / closing member 6 is closed in this accommodated state, the dust separation device 11 is sandwiched and fixed between the opening / closing member 6 and the placing portion 4.

  The cyclone portion 12 has a dust inlet 12a that opens forward in the inside thereof. The dust inlet 12a communicates with the rear end of the main body inlet 8 with the opening / closing member 6 closed. The cyclone unit 12 separates dust in the dust-containing air flowing in from the dust inlet 12a from the air using the inertia force of the dust.

  The dust cup unit 13 has a dust collection chamber (not shown) that collects dust separated from air by the cyclone unit 12. A cup handle 15 is integrally provided on the front surface of the dust cup portion 13. The rear surface of the dust cup portion 13 is open, and the pleated filter 14 is detachably fitted to the open portion. The pleated filter 14 collects fine dust contained in the air sucked into the electric blower 9 after being separated from dust through the cyclone portion 12 by filtration separation.

  A number of ridges included in the pleated filter 14 extend in the vertical direction. The rear surface of the pleated filter 14 is exposed behind the dust cup portion 13. The dust separator 11 has an openable / closable bottom plate (not shown). By opening the bottom plate with the dust separating device 11 removed from the vacuum cleaner main body 2, dust removed from the pleated filter 14 as described later, and dust collected separately in the dust collecting chamber are removed. , And can be discharged from the dust separator 11.

  As shown in FIG. 3, the dust removing device 21 is disposed near the front surface of the boundary wall 2 c of the cleaner body 2. In a state where the dust separation device 11 is disposed on the mounting portion 4, the pleated filter 14 of the dust separation device 11 is opposed to the dust removal device 21 from the front side.

  As shown in FIGS. 4 and 5, the wall 22a of the device holder 22 provided in the dust removing device 21 faces the boundary wall 2c, and a vent 23 communicating with the accommodation space S is formed in the wall 22a. The air vent 23 communicates with an air inlet (not shown) provided in the boundary wall 2c, and the air passing through the air inlet is sucked into the electric blower 9. Therefore, when the electric blower 9 is operated, the intake negative pressure is spread to the suction system via the dust separation device 11, so that dust on the surface to be cleaned is sucked.

  In addition to the device holder 22, the dust removal device 21 includes a movable dust removal body 24, a gear train 25, a drive rack 26, and the like.

  The movable dust remover 24 is supported by two guide rods 27 extending in the left-right direction of the cleaner body 2 on the front surface of the device holder 22, and using these as guides in the width direction of the cleaner body 2 ( It is provided so that it can reciprocate in the left-right direction. Dust removal projections 28 are provided at both ends in the longitudinal direction of the movable dust remover 24 so as to protrude forward, and the movable dust remover 24 is provided with a driven rack 29 over the entire length in the longitudinal direction.

  The movement trajectory of the pair of dust removal protrusions 28 is set so as to intersect the rearward ridge of the pleat filter 14. Therefore, each time the movable dust removing body 24 is moved, the dust removing projection 28 oscillates the pleat filter 14 in accordance with the flipping of the pleat filter 14 so as to remove fine dust adhered to the pleated filter 14. it can. In this case, one dust removal protrusion 28 flips the rearward fold within the half width of the pleat filter 14, and the other dust removal protrusion 28 flips the rearward fold within the other half width of the pleat filter 14. It has become.

  The gear train 25 is rotatably supported on the wall portion 22 a of the apparatus holder 22. The gear train 25 includes an input small gear 25a, an intermediate large gear 25b, an intermediate small gear 25c, and a driving small gear 25d.

  The input small gear 25a and the intermediate large gear 25b are coaxial and rotate together. The intermediate small gear 25c and the driving small gear 25d are coaxial and rotate together. The intermediate large gear 25 b and the intermediate small gear 25 c are engaged with each other, and the driving small gear 25 d is engaged with the driven rack 29 of the movable dust removing body 24. For this reason, when the input small gear 25 a is rotated, the movable dust removing body 24 is moved to the left and right along the guide rod 27 through the engagement between the driving small gear 25 d and the driven rack 29.

  The drive rack 26 is provided so as to be movable in the vertical direction, and is meshed with the input small gear 25a. The position of the drive rack 26 is regulated by a guide (not shown) so as not to disengage from the input small gear 25a. The amount of movement of the drive rack 26 in the vertical direction is set so that the rotation necessary for reciprocating the movable dust remover 24 once can be given to the drive small gear 25d.

  The dust removing device 21 configured as described above is connected to the opening / closing member 6 so as to remove dust from the pleated filter 14 in conjunction with the opening operation of the opening / closing member 6. For this purpose, for example, a part of the opening / closing member 6 on the side of the hinge shaft 7 and the arm portion 26a (see FIG. 5) of the drive rack 26 are connected by an interlocking means, for example, a link 31. Specifically, the upper end portion of the link 31 is pivotally connected to the opening / closing member 6 by the upper pivot 32, and the lower end portion of the link 31 is pivotable to the upper end portion of the arm portion 26 a of the drive rack 26 by the lower pivot 33. It is connected.

  The vacuum cleaner 1 holds the dust separation device 11 between the mounting portion 4 and the opening / closing member 6, and the body connection end portion of the dust suction hose provided in the suction system at the body suction port 8 of the opening / closing member 6. It is used by operating the electric blower 9 in the cleaner body 2 in a connected state. By this cleaning, the sucked dust-containing air is separated into coarse dust and air by the cyclone unit 12 of the dust separation device 11, and the coarse dust therein is collected in the dust cup unit 13, while the cyclone is collected. Fine dust and air are separated by the pleated filter 14 disposed downstream of the section 12, the fine dust is collected by the pleated filter 14, and the air passes through the vent 23 of the dust removing device 21 to the electric blower 6. After being sucked in, it is discharged out of the cleaner body 2.

  In order to throw away the dust collected in the dust separator 11 in a state where the operation of the electric blower 9 is stopped after cleaning or the like, the dust separator 11 is removed from the cleaner body 2. In this case, when the user manually opens the opening / closing member 6, the restriction of the dust separating device 11 with respect to the cleaner body 2 is released, and the dust separating device 11 can be taken out from the housing space S of the cleaner body 2. Become.

  At the same time, dust removal of the pleat filter 14 by the dust removing device 21 is performed in conjunction with the opening operation of the opening / closing member 6. That is, when the opening / closing member 6 rotates with the hinge shaft 7 as a fulcrum from the closed state as shown in FIG. 5B and is opened upward through the state shown in FIG. 5A, the link 31 is opened. The drive rack 26 is raised by being pulled up.

  Accordingly, the input small gear 25a of the gear train 25 meshing with the drive rack 26 is rotated, and the rotation is transmitted to the drive small gear 25d via the intermediate large gear 25b and the intermediate small gear 25c. As a result of the rotation of the driving small gear 25d, the movable dust removing body 24 having the driven rack 29 meshing with the driven small gear 25d is guided by the guide rod 27 and orthogonal to the direction in which the pleats of the pleat filter 14 extend. 2 is moved in the width direction. Therefore, the pleat filter 14 can be vibrated by flipping the ridge protruding backward from the pleat filter 14 by the pair of dust removal projections 28 of the movable dust removal body 24.

  Therefore, the dust adhering to the pleat filter 14 can be removed by an operation of opening the opening / closing member 6 inevitably for dust disposal without requiring a dedicated operation for operating the dust removing device 21. Since the opening / closing member 6 is already open when the dust separation device 11 is taken out from the cleaner body 2 after this dust removal, it is possible to reduce time and effort required for a series of operations from dust removal to dust disposal.

  Note that by opening a bottom plate (not shown) of the dust separator 11 taken out from the storage space S, the dust collected in the dust separator 11 is discharged to the outside, thereby completing the dust disposal. In this dust disposal, after the dust removing device 21 is operated in conjunction with the opening / closing member 6 being opened, the removed fine dust is discharged as soon as the bottom plate is opened. The fine dust removed from 14 can be easily discharged out of the dust separator 11.

  Further, the dust separation device 11 whose bottom plate is closed after the above dust disposal is held in the cleaner body 2 by being sandwiched from above and below by closing the opening / closing member 6 after being accommodated in the accommodation space S. The movable dust remover 24 returns to the original position shown in FIG. 4 in conjunction with the closing of the opening / closing member 6. In this case, the link 31 is provided as the opening / closing member 6 rotates about the hinge shaft 7 and closes downward so that the state shown in FIG. 5 (B) is obtained after the state shown in FIG. 5 (A). This is done by pushing down the drive rack 26 via the.

  As a result, the input small gear 25a of the gear train 25 meshed with the drive rack 26 is rotated in the opposite direction to that when the opening / closing member 6 is opened, so that the rotation is transmitted via the intermediate large gear 25b and the intermediate small gear 25c. The movable dust removing body 24 having the driven rack 29 that is transmitted to the drive small gear 25d and meshes with the driven small gear 25d is guided by the guide rod 27 extending in the width direction of the cleaner body 2. Then, the original position shown in FIG. 4 is returned.

  In a state where the dust separating device 11 is held in the cleaner body 2, the dust inlet 12 a of the dust separating device 11 is communicated with the rear end of the main body suction port 8 of the opening / closing member 6, and interlocked with the operation of closing the opening / closing member 6. Then, the pair of dust removal projections 28 of the movable dust removal body 24 returned to the original position shown in FIG. 4 enter the rearwardly opened groove between the pleat filter 14 projecting backward, and the next dust removal operation. Prepare for.

  The present invention is not limited to the one embodiment. For example, the means for linking the opening / closing member 6 and the dust removing device 21 can rotate the hinge shaft 7 integrally with the opening / closing of the opening / closing member 6 instead of the link, and the drive gear can be applied to the hinge shaft 7 instead of the drive rack. A structure in which the drive gear is directly engaged with the input small gear 25a and interlocked, or the input small gear 25a and the drive gear are interlocked via a plurality of rotation transmission gears meshed with the hinge shaft 7. The configuration can also be adopted. In the present invention, the dust collecting means may be a bag filter using paper or cloth. Therefore, the opening and closing member used in the present invention is not limited to the one that holds the dust collecting means.
