  The partition wall 33 is formed with an inclination preventing rib 53 that prevents the sliding lever 37 from tilting during operation, and a cover body 54 that covers the window 40, the rotation lever 35, and the sliding lever 37 is held and fixed. . The cover body 54 is formed with a plurality of claws 54a, while the partition wall body 33 is provided with a hole (not shown) for fitting into the claw 54a, so that the cover body 54 can be easily fitted into the partition wall body 33 with claws. So, it can be detachably fixed.

  Similarly to the partition wall 33, the cover body 54 has a bearing 54 b that pivotally supports the rotation lever 35 and a direction in which the contact portion 36 contacts the rib body 31 or the protruding rib 32. That is, a spring receiving portion 54c is formed that holds the contact spring 42 that is urged to rotate so that the sliding lever 37 slides toward the diaphragm 26 side.

  The cover body 54 further includes a holding portion 55 that holds the cover member 51 between the partition wall 23 and a pressing portion for preventing the cover member 51 from coming off the opening 49. Further, the cover body 54 is surrounded by a holding rib 56 formed in the upper case 10.

  On the other hand, a holding frame 57 that pivotally supports the diaphragm 26 is provided in front of the communication port 25 provided in the partition wall 23 in the dust collecting chamber 17, and is detachably set in an insertion portion 58 provided in the lower case 9. .

Further, when the dust collection bag 19 is vibrated, the dust removing unit 64 operates to a position protruding from the holding frame 57 to the outside. The dust removing portion 64 of the diaphragm 26 periodically oscillates between the position protruding from the holding frame 57 and the regulating body 63 by the periodic operation of the rotating lever 35 and the sliding lever 37.

  The diaphragm 26 or the holding frame 57 is formed with a hook portion 65 in which a finger or the like can be hooked at the time of removal in a lattice shape.

  About the vacuum cleaner comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  When the power cord 28 is pulled out, the protruding rib 32 formed on the cord reel 29 also rotates, and when the contact portion 36 rides on the protruding rib 32, the rotating lever 35 rotates and the sliding operation portion 38 is moved. The sliding operation part 38 pushes the engaging part 47 of the sliding lever 37 and the sliding lever 37 slides to the rear of the cleaner body 1. The press-fit fixing portion 50 of the covering member 51 moves rearward together with the slidable vibration transmitting portion 48, and the diaphragm 26 does not have the pressing force of the covering member 51 on the diaphragm operating portion 60. Tilt backwards.

  When the abutting portion 36 passes over the protruding rib 32, the rotating lever 35 rotates with an impact force and returns to the original position, so that the sliding lever 37 quickly slides forward together with the interlocking covering member 51. The covering member 51 strikes the diaphragm operating unit 60 of the diaphragm 26. Then, the diaphragm 26 moves toward the dust bag 19 with an impact force and can apply a large vibration to the dust bag 19, so that the dust attached to the inside of the dust bag 19 is efficiently collected. The dust collection performance can be improved by reducing the decrease in suction wind.

  As described above, according to the present embodiment, the cover body 54 that covers the window portion 40 can be molded in accordance with the shape of the partition wall body 33, so that the gap between the cover body 54 and the partition wall body 33 can be reduced, and the window The exhaust air and dust of the electric blower 12 from the portion 40 can be reliably prevented from entering the cord reel 29, and the rotation operation of the rotation lever 35 and the dust removal operation associated therewith can always be kept in a good state. .

  Further, since the cover body 54 is also provided with a bearing portion 54b for pivotally supporting the rotation lever 35, the rotation lever 35 can be pivotally supported on the cover body 54 in advance. By simply engaging the partition wall body 33 with the claws 33, the turning lever 35 can be instantly assembled into the partition body 33, and assembly is facilitated.

  Further, by providing the tilt prevention rib 53 that regulates the tilt of the sliding lever 37 that drives the diaphragm 26, the sliding operation of the sliding lever 37 linked to the rotating operation of the rotating lever 35 is stabilized. The diaphragm 26 can be reliably driven to apply vibration to the dust bag 19.

  Further, since the spring receiving portion 54c for holding the contact spring 42 is formed on the cover body 54, the rotating lever 35, the contact spring 42 and the cover body 54 can be unitized, and the partition body 33 for dust removal related parts. Can be instantly incorporated into the unit, making assembly easier.

  In addition, since the cover body 54 covering the window 40 facing the contact portion 36 of the rotation lever 35 is detachable from the partition wall body 33, the operation of the rotation lever 35 can be easily confirmed.

  Further, since the cover body 54 is formed with a holding portion 55 for preventing the cover member 51 from coming off from the partition wall 23, the cover body 54 can be simply nail-fitted to the partition wall body 33 without using extra parts. The cover member 51 can be prevented from coming off, and air leakage at the opening 49 provided in the partition wall 23 can be reliably prevented, so that the suction force does not decrease.

  Further, since the plurality of protruding ribs 32 are formed, vibration can be applied to the dust collection bag 19 by the vibration plate 26 a plurality of times when the power cord 28 is pulled out, so that the number of hits can be increased and the dust removal effect can be expanded. It will be a thing.

  Further, since the engaging portion 47 of the sliding lever 37 is shaped so as to sandwich the sliding operation portion 38 formed on the rotating lever 35 in the front-rear direction, the rotating operation of the rotating lever 35 can be smoothly converted into a horizontal operation. Since the operation of the sliding operation unit 38 can be smoothly interlocked, the dust adhering to and accumulating inside the dust bag 19 can be efficiently removed.

  The rotating lever 35 is pivotally supported in the vicinity of the cord reel 29, and includes a contact portion 36 formed on the rotating lever 35, a sliding lever 37, and a diaphragm operating portion 60 formed on the diaphragm 26. Since they are arranged on a substantially straight line, the dust removal operation can be transmitted in the shortest distance. As a result, the dust removing means 27 can be made compact, and the vacuum cleaner body can be reduced in size and weight.

  The rib body 31 formed on the cord reel 29 is formed in a shape connected to both ends of the projecting rib 32, and is disposed inside the outer periphery of the cord reel 29, and the contact portion 36 of the rotating lever 35 is substantially circular. Since it is formed in an arc shape, when the cord reel rotates, the operation of the contact portion 36 riding on the protruding rib 32 becomes smooth, and as a result, noise during dust removal can be reduced.

  Further, since the wear preventing body 41 for preventing wear is provided on the contact portion 36 with a metal material such as a screw, it is possible to prevent abrupt wear and to maintain a durable and comfortable cleaning.

  When the operation unit 43 is operated during winding of the power cord 28, the release rib 46 operates the contact release unit 39 of the rotation lever 35, and the rotation lever 35 rotates. Immediately after the contact portion 36 of the rotating lever 35 moves away to a position where it does not contact the projection rib 32, the brake release portion 44 operates the brake lever 34 to release the rotation restraint of the cord reel 29. Then, the power cord 28 is wound up. As a result, when the power cord 28 is wound, it can be smoothly wound without generating extra load or noise, and the usability can be improved.

  Since the release rib 46 formed on the operation unit 43 is formed on a part of the outer periphery of the operation unit 43, the release rib 46 can be formed in the same size as the conventional operation unit, and a vacuum cleaner by adding functions. The main body 1 can be prevented from being enlarged, and comfortable cleaning can be performed.

  In addition, as shown in FIG. 12, when it is desired to remove dust when the power cord 28 is not pulled out, when the operation unit 43 is pushed down, the release rib 46 contacts the contact release unit 39 formed on the rotary lever 35 and rotates. The lever 35 rotates, the sliding operation part 38 moves, the sliding operation part 38 pushes the engaging part 47 of the sliding lever 37, and the sliding lever 37 slides to the back of the cleaner body 1. The press-fit fixing portion 50 of the covering member 51 moves rearward together with the slidable vibration transmitting portion 48, and the diaphragm 26 has no pressing force of the covering member 51 on the diaphragm operating portion 60. Tilt backwards by force. Subsequently, when the hand is released from the operation portion 43, the contact of the release rib 46 with the contact release portion 39 is released by the elastic force of the operation portion spring 45, and the rotation lever 35 is elasticized by the contact spring 42. Therefore, the sliding lever 37 quickly slides forward together with the interlocking cover member 51 and collides with the diaphragm operating portion 60 of the diaphragm 26. Then, the diaphragm 26 moves toward the dust bag 19 with an impact force and can apply a large vibration to the dust bag 19, so that the dust bag 19 can be removed until it is satisfied as much as desired. Can be cleaned comfortably.

  Further, even if the sliding lever 37 operates between the electric blower chamber 22 and the dust collecting chamber 17 having a pressure difference, the covering member 51 covers the sliding lever 37 and forms a convex shape on the outer periphery. 23, the holding and fixing to the opening 49 formed in the partition wall 23 can be ensured, and even if an external force other than normal use is applied, the dust collecting chamber 17 is not detached or displaced. The inner airtightness is always ensured, and it can be smoothly transmitted to the diaphragm without obstructing the operation of the sliding lever 37. The cover member 51 is formed of a soft material such as rubber, covers the sliding lever 37, and is provided with a press-fit fixing portion 50 that is press-fitted and fixed to the sliding lever 37, so that the operation of the sliding lever 37 is not hindered. The dust can be smoothly transmitted to the diaphragm 26, and the dust deposited and deposited inside the dust bag 19 can be efficiently removed.

  Since the thickness of the front end portion of the covering member 51 that contacts the diaphragm 26 is formed to be thicker than the peripheral thickness, the sliding lever 37 is operated repeatedly so that the front end portion of the covering member 51 and the diaphragm 26 are moved. Even if the tip part is abutted to some extent and wears, the airtightness in the dust collecting chamber 17 can always be ensured because the tip part is not torn and no hole is formed.

  Since the rotation shaft 59 of the diaphragm 26 is pivotally supported at a substantially central height position of the holding frame 57, the torque required to vibrate the diaphragm 26 can be reduced. The pull-out force is lightened and the operability can be improved, and when the full dust bag 19 is taken out, the diaphragm 26 moves, so that it can be taken out without being caught.

  Since the holding frame 57 is provided with an enclosing portion 62 that covers the cover member 51 and the diaphragm operating portion 60, even if the dust bag 19 spreads with dust, the vibration does not hinder the operation of the diaphragm operating portion 60. The vibration of the plate 26 can be reliably applied to the dust bag 19.

  Since the movable range of the diaphragm operating unit 60 is narrower than the movable range of the sliding lever 37, even if the dust bag 19 spreads and the diaphragm 26 is pressed backward, the sliding lever can be pulled by the power cord 28 or the like. Since 37 slides in the front-rear direction, vibration can be applied to the diaphragm 26 and dust can be sucked in until the dust bag 19 is full.

  A plurality of dust removing portions 64 are formed on a wide surface so as to come into contact with the surface, and periodically swing between a position protruding from the holding frame 57 and the regulating body 63, so that dust can be effectively removed.

  The diaphragm 26 or the holding frame 57 is formed with a hook portion 65 that can be hooked with a finger or the like at the time of removal, so that the removal can be easily performed.

  Since the holding frame 57 is detachable from the lower case 9, when selling an inexpensive vacuum cleaner, etc., the model can be discriminated with or without the dust removal mechanism simply by attaching and replacing the holding frame 57 without the diaphragm 26 attached. Can be easily realized. Similarly, the model can be easily differentiated by simply removing the dust removing means such as the rotation lever 35.

  As described above, the vacuum cleaner according to the present invention reliably prevents a part of the exhaust from the electric blower from entering the cord reel side, and always provides a stable dust collection bag dust removal performance. It is particularly useful for vacuum cleaners for home use and business use.
