JP 2006-141597 A

  However, in the configuration of the conventional vacuum cleaner described above, the inner diameter of the through-hole 76 is formed to be large in order to allow the mounting shaft 73a to rotate, and therefore the outer shape of the packing 77 must be increased. . For this reason, although it is added to the packing 77 due to air pressure (external air pressure applied toward the negative pressure dust collection chamber 71 side), the air leaks between the inner periphery of the packing 77 and the groove 73d provided on the mounting shaft 73a. There is a problem that it is likely to occur and the dust suction performance is lowered.

  As one means for solving this problem, it is conceivable to increase the rigidity by increasing the thickness of the packing 77. However, in this case, the rotation operation of the mounting shaft 73a becomes dull (it becomes difficult to move), and as a result, vibration occurs. The movement of the plate 70 also becomes dull, and the dust removal performance of the dust bag 72 is significantly lowered.

  The present invention solves the above-described conventional problems, and improves the dust removal performance of the dust collection bag, and also ensures the air tightness in the dust removal mechanism and can prevent the deterioration of the suction performance.

The diaphragm is driven by a fixed part, and the cover member is bottomed, and in conjunction with the sliding movement of the sliding lever, only the press-fit fixing part moves back and forth. In addition, the surface area of the covering member is smaller than that of the conventional member, and the end of the sliding lever is press-fitted into the press-fit fixing portion, so that the deformation of the covering member due to external air pressure is reduced, and the amount of the covering member is reduced accordingly. The thickness of the side portion can be reduced, the follow-up performance of the press-fit fixing portion that drives the diaphragm to the movement of the sliding lever is improved, and the dust removal performance is improved.

  Further, the distance between the release rib 46 and the contact release portion 39 is configured at a position closer to the distance between the brake release portion 44 and the brake lever 34.

  The sliding lever 37 is formed with an engaging portion 47 that engages with a sliding operation portion 38 provided on the rotation lever 35 at one end in a shape that sandwiches the sliding operation portion 38 in the front and rear directions of operation, and at the other end. A vibration transmitting portion 48 that applies vibration to the diaphragm 26 is formed.

  The partition wall 23 is provided with an opening 49 through which the sliding lever 37 passes, and the covering member 51 that covers the vibration transmitting portion 48 of the sliding lever 37 and that has a press-fit fixing portion 50 that is press-fitted and fixed to the vibration transmitting portion 48. The opening 49 is fitted and fixed.

  The cover member 51 is formed of a soft material such as rubber by forming a flange-like convex portion 52 on the outer periphery and making the thickness of the press-fit fixing portion 50 thicker than the peripheral thickness.

  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 forms a bearing portion that pivotally supports the rotation lever 35 similarly to the partition wall body 33, and holds a contact spring 42 that urges the rotation lever 35. Further, in order to prevent the cover member 51 from coming off, a clamping portion 55 that clamps the cover member 51 between the partition wall 23 is formed. 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. . A rotating shaft 59 of the diaphragm 26 is pivotally supported at a substantially central height position of the holding frame 57.

  The diaphragm 26 is provided with a diaphragm operating section 60 that receives vibration from the press-fit fixing section 50, and a diaphragm spring 61 that biases the diaphragm 26 toward the partition wall 23 on a substantially vertical line of the diaphragm operating section 60.

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-fitting and fixing portion 50 of the cover member 51 moves rearward together with the slidable vibration transmitting portion 48, and the diaphragm 26 does not have the pressing force of the cover member 51 on the diaphragm operating portion 60. To 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 cover member 51. The press-fit fixing part 50 of the covering member 51 collides with the diaphragm operating part 60 of the diaphragm 26. Then, the vibration plate 26 moves toward the dust collection bag 19 with an impact force and applies a large vibration to the dust collection bag 19. Therefore, the dust adhered to and accumulated in the dust collection bag 19 is efficiently removed. It is possible to improve the dust collection performance by reducing the decrease in suction air.

  As described above, according to the present embodiment, the electric blower chamber 22 that houses the electric blower 12 that generates suction air, the dust collection chamber 17 that houses the dust collection bag 19 that collects dust, and the electric blower A partition wall 23 that partitions the chamber 22 and the dust collection chamber 17 and has an opening 49 in a part thereof, a cord reel 29 that winds and stores a power cord 28, and the dust collection chamber 17 disposed in the dust collection chamber 17. A diaphragm 26 that removes dust adhering to the bag 19, a rotation lever 35 that rotates in conjunction with the cord reel 29 that rotates at least when the power cord 28 is pulled out, and one end that is associated with the rotation lever 35. And a sliding lever 37 that slides back and forth in conjunction with the turning operation of the turning lever 35, and is fitted in the opening 49 in a substantially cylindrical shape with a bottom, and the sliding lever 37 Press-fit fixing part where the end is press-fit A cover member 51 having 0, and the diaphragm 26 is driven by the press-fit fixing portion 50 in conjunction with the sliding operation of the slide lever 37. The cover member 51 is bottomed. In addition, since the press-fitting and fixing portion 50 only moves back and forth in conjunction with the sliding operation of the sliding lever 37, the airtightness is excellent, and the surface area of the covering member 51 is smaller than that of the conventional one, and the sliding lever 37 is further reduced. Since the end portion of the cover member 51 is press-fitted into the press-fit fixing portion 50, the deformation of the cover member 51 due to the external air pressure is reduced, and the thickness of the side portion of the cover member 51 can be reduced correspondingly. The press-fit fixing part 50 for driving the slidable lever 37 is improved in the followability to the movement of the sliding lever 37, and the dust removal performance is improved.

  In addition, since the tilt prevention rib 53 for restricting the tilt of the slide lever 37 is provided, the slide operation of the slide lever 37 linked to the pivot operation of the pivot lever 35 is stabilized, and the diaphragm 26 is reliably driven. Thus, vibration can be applied to the dust bag 19.

  In addition, since the movable range of the sliding lever 37 is set wider than the movable range of the diaphragm 26, even when the dust bag 19 spreads and the diaphragm 26 is pressed backward, when the power cord 28 is pulled out. When the sliding lever 37 slides to the lowest position, the sliding lever 37 is located behind the diaphragm 26. Therefore, when the sliding lever 37 slides forward, the diaphragm 26 The dust can be reliably removed by vibration, and the dust can be sucked until the dust bag 19 is full.

  Further, the rotating lever 35 is provided with an abutting portion 36 that abuts against the protruding rib 32 provided on the cord reel 29, and the abutting portion 36, the sliding lever 37, the press-fit fixing portion 50 of the diaphragm 26 and the abutting portion 36. Since the contacting diaphragm operating unit 60 is arranged in a substantially straight line, the dust removing operation can be transmitted in the shortest distance, the dust removing means 27 can be configured compactly, and the vacuum cleaner body can be reduced in size and weight.

  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.

  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 can effectively remove dust deposited and accumulated inside the dust collection bag, and can reduce the reduction in suction air and improve the dust collection performance. Since it can be reduced in size and weight, it is particularly useful for vacuum cleaners for home use and business use.
