  The operation of the electric vacuum cleaner configured as described above will be described with reference to FIGS.

  With the dust bag 7 set in the main body 1 as shown in FIG. 3, the vacuum cleaner body is operated to collect the dust in the dust bag 7, and the dust is collected in the dust bag 7. As an operation when the dust bag 7 is taken out from the chamber 3, a reclining type mouth plate guide is formed by releasing the lock of the clamp 75 on the mouth plate 7 a formed of a material such as paper adhered to the dust bag 7. 73 (hereinafter referred to as a mouth plate guide) is inclined toward the electric blower 8, and the mouth plate 7 a is drawn along the mouth plate guide 73 in the opening direction of the dust collection chamber 3.

  During this operation, the moving member 200 in contact with the dust bag 7 simultaneously pulls out the dust bag 7 as shown in FIGS. 6 to 9 and simultaneously with the dust bag 7 in the opening direction of the dust chamber 3. Therefore, the friction resistance between the dust collection bag 7 and the inner wall of the dust collection chamber 3 is reduced, and even if the dust is full, it is easy to collect dust without imposing a great load on the user. The bag 7 can be taken out and discarded.

  Further, the more dust is collected, the higher the moving effect of the moving member 200 can be as the dust bag 7 comes into contact with the moving member 200 more strongly or the contact area increases. Further, as shown in FIG. 9, the moving member 200 moves in the opening direction of the dust collecting chamber 3, but the moving base member 201 is rotatably supported by the rib 310 of the dust collecting chamber 3, and thus the dust collecting bag 7. When the load is received from the dust collection bag 7 of the moving member 200 is positioned closer to the opening side than the engaging protrusion 203 of the moving base member 201, at the same time as the effect of moving the moving member 200 is obtained. Further, by opening the moving base member 201 in the opening direction of the dust collecting chamber 3 (inclining in the direction of taking out), it is possible to improve the convenience of the user and greatly reduce the load at the time of taking out.

  Further, in order to improve the dust collection capacity (slimming of the moving member 200 in the dust collecting chamber 3) and simplify the components, the moving member 200 can be used as a rib 310 of the dust collecting chamber 3 alone as shown in FIG. By engaging with the engagement hole 300 and disposing, the load when the dust bag 7 is taken out can be reduced.

  Next, a second embodiment of the present invention will be described with reference to FIGS.

  The moving member 200 is located on the upstream side of the electric blower 8 and constitutes a communication hole 801 between the electric blower chamber 800 in which the electric blower 8 is disposed and the dust collection chamber 3. 310, at least one engagement hole 300 is formed in the rib 310, and the engagement projections 203 of the engagement hole 300 and the moving base member 201 are formed on the left and right ribs 310 provided in the dust collecting chamber 3. It is movably engaged so as to be pinched. Further, the moving base member 201 is provided with at least one engaging hole 206 movably engaged with the moving member 200 on both sides, and the moving member 200 is disposed inside the engaging hole 206. Engagement protrusions 204 are disposed on the outer portion of the moving member 200 so that the number of engagement protrusions 204 is equal to or less than the number of engagement holes of the movement base member 201. 204 is movably and detachably engaged. With this configuration, by providing the moving member 200 in the communication hole 801 portion of the electric blower chamber 800 in the dust collection chamber 3 where dust accumulation is most likely to concentrate or where accumulation starts in the dust collection bag 7, By effectively moving the moving member 200, the load on the user can be reduced.

  Next, a third embodiment of the present invention will be described with reference to FIGS. 4 and 11 to 13.

  By disposing the moving member 200 at a position facing the opening side in the dust collecting chamber 3 as shown in FIG. 11, the moving member 200 moves simultaneously when the dust collecting bag 7 is taken out. The bottom moving member 202 formed integrally with (FIG. 12A) or separately moves toward the opening side simultaneously or with a time difference. In the case of a separate body, as shown in FIG. 12B, the bottom moving member 202 is configured to be rotatably fitted to the lower engaging hole 207 of the moving member 200 and the bottom moving member 202 engaging protrusion 205. When the dust collection bag 7 is taken out, the force for taking out the dust collection bag 7 from the opening side is further reduced by pushing or lifting from the side facing the opening side (drawing direction), and at the same time, the density of the dust etc. Even in the dust bag 7 containing a lot of high dust, the shape of the dust bag 7 is distorted and the dust collection bag 7 containing any kind of dust is surely opened, including the case where the dust is accumulated unevenly. Can be taken out.

  Further, when removing the moving member 200, the bottom moving member 202 formed separately can be folded and placed with reference to the rotation axis as shown in FIG.

  Furthermore, since it can be set in a folded state when set in the dust collection chamber 3, it is easy to set the movable base member 201 in the dust collection chamber 3 or the engagement hole 300 of the rib 310.

  Next, a fourth embodiment of the present invention will be described with reference to FIGS.

  Through the movable base member 201 or independently, the movable member 200 is rotatably supported by the engagement hole 300 and the engagement protrusion 203 of the rib 310 in the dust collecting chamber 3. When the vacuum cleaner body is operated and dust is sucked in, the dust collection bag 7 is most likely to accumulate dust accumulation, or the communication port 801 with the electric blower chamber 800 in the dust collection chamber 3 where accumulation starts. The moving member 200 located on the upstream side of the vacuum cleaner vibrates by itself or another driving means before and after the operation of the main body of the vacuum cleaner, and the dust adhering to the inside of the dust bag 7 is shaken and shaken to suck The power can be sustained. As a result, a large amount of dust can be efficiently collected in the dust collection bag 7 (disposable bag filter).

  Next, an example of drive means for applying vibration to the dust bag will be described. On the upper surface of the dust collection chamber 3, there is provided a lid body 5 having an opening portion through which a dust collection bag 7 (paper pack) is put in and out, and covering the opening portion so as to be freely opened and closed. The lid 5 is rotatably supported by the cleaner body 1, and an upper horizontal dust removing body 6 is held on the lid 5 that can be freely opened and closed. A support shaft 81 of the upper horizontal dust remover 6 is rotatably attached to 82 of the lid 5. Similarly, the support shaft 89 of the upper horizontal dust removing body auxiliary portion 83 is rotatably attached to the support receiving portion 85 of the dust collecting lid 5 so as to operate in conjunction with the upper horizontal dust removing body 6.

  Dust removal of the dust bag 7 is performed by dust removing means. As shown in FIG. 15, the dust removing means includes a dust removing rotating body 12 and a power branching mechanism 25 that are driven by the moving member 200 and the cord reel 9 and cause the moving member 200 to vibrate.

  The moving member 200 is provided in the dust collecting chamber 3, and the dust bag 7 placed in the dust collecting chamber 3 is vibrated by the moving member 200 and the dust attached to the inside is shaken off.

  The dust removal drive transmission unit 11 (FIG. 16) is provided on the inner bottom portion of the cleaner body 1. The dust removal drive transmission unit 11 includes a dust removal rotary body 12 and a transmission gear 13. As shown in FIG. 15, the transmission gear 13 meshes with the drive gear 14 of the cord reel 9.

  The power branch mechanism 25 is provided inside the dust collecting chamber 3, transmits power to the upper horizontal dust removing body 6 using the rotational force of the dust removing rotary body 12, and the upper horizontal dust removing body auxiliary unit 83 is interlocked. Details of the power branch mechanism 25 will be described later.

  The rotation of the cord reel 9 is transmitted to the dust removal rotating body 12 of the dust removal drive transmission unit 11 through the drive gear 14 and the transmission gear 13. Due to the rotation of the dust removal rotary body 12, the moving member 200 is vibrated, and the dust collection bag 7 is dust-removed.

  The dust removing member will be described in more detail with reference to FIGS. 15 and 17 to 20.

  The moving member 200 includes a moving base member 201, a bottom moving member 202, an upper horizontal dust removing body 6, and an upper horizontal dust removing body auxiliary portion 83. The lower end of the moving base member 201 and the rear end of the bottom moving member 202 are coupled to each other by a support shaft 17 so as to be rotatable. The moving base member 201 and the bottom moving member 202 rotate in the range of about 90 (the state shown in FIG. 20a) opened from the folded 0 degree (close to the state shown in FIG. 20b).

  The moving base member 201 has a stopper 18 at the lower end. When the bottom moving member 202 is opened to 90 degrees, the bottom moving member 202 is held by the stopper 18 and cannot be opened any further.

  The maximum opening angle may be 90 degrees or less or 90 degrees or more as long as the bottom moving member 202 does not contact the inner bottom of the dust collection chamber 3. The moving base member 201 has a dust removing frame body portion 20 provided with support shaft protrusions 203 at both upper ends.

  As shown in FIGS. 3 and 21, the cleaner body 1 includes an intermediate partition wall 21 that partitions the dust collection chamber 3 and the rear chamber. The intermediate partition wall 21 is provided with two ribs 310 running vertically on the dust collection chamber 3 side with a space therebetween, and the rib 310 has a support hole 23 on the upper side as shown in FIG. The wall 21 has a locking groove 44 for attaching the power branch mechanism 25.

  The support shaft protrusion 203 of the moving base member 201 is rotatably fitted in the support hole 23 of the rib 310. Accordingly, the moving base member 201 and the bottom moving member 202 are placed in the dust collection chamber 3 so as to be freely swingable.

  As shown in FIG. 22a, the rib 310 has an inclined groove 24a formed on the opposing surface (inner surface) from the upper side of the support hole 23 toward the rib 310. The inclined groove 24a is inclined outward toward the upper side. The support shaft protrusion 203a also has an inclined surface on the end side. For this reason, the support shaft protrusion 203a is easily fitted into the support hole 23 by sliding the support shaft protrusion 203a from the top to the bottom along the inclined groove 24a. The moving base member 201 and the bottom moving member 202 are easily attached.

  Further, in some cases, the rib 310 has an inclined groove 24b in which at least one of the opposing surfaces (inner side surfaces) is formed from the front side (the hose insertion port 4 side) of the support hole 23 toward the rib 310 as shown in FIG. Have The inclined groove 24b is inclined outward toward the front side. At this time, the support protrusion 203b can be easily fitted into the support hole 23 by sliding the support shaft protrusion 203 into the shape of the support shaft protrusion 203b so as to slide on the inclined groove 24b perpendicularly to the intermediate partition wall 21 from the front side. .

  Next, the power branch mechanism 25 will be described. The power branch mechanism 25 is in the dust collection chamber, is disposed between the moving base member 201 and the intermediate partition wall 21, and is attached to a locking groove 44 provided in the intermediate partition wall 21.

  The power branch mechanism 25 is engaged with the protrusion 27 of the dust removal rotary body 12 of the dust removal drive transmission unit 11 and the cam crank protrusion 28 of the power branch mechanism 25 and interlocks with the rotational movement of the dust removal rotary body 12. In this case, the joint portion is pulled downward and returned to its original position by the urging spring 29 of the power branch mechanism 25 to perform reciprocating motion. The cam crank 30 of the power branch mechanism 25 causes the dust removal rotating body 12 to move back and forth. In this case, the driving force of the rotary motion is converted upward and the power is transmitted to the upper horizontal dust removing body 6, and the power is transmitted to the upper horizontal dust removing body auxiliary unit 83.

  The dust removal rotary body 12 has a dust removal spring 31 wound around the outer periphery. The dust removal spring 31 is spirally wound along the longitudinal direction of the dust removal rotating body 12, and as shown in FIGS. It has an uneven shape. The biasing spring 26 provided in the moving base member 201 of the moving member 200 presses the moving base member 201 toward the intermediate partition wall 21.

  The upper horizontal dust remover and the upper horizontal dust remover auxiliary unit will be described. The upper lateral dust removing body receives an upward load from the dust removing rotary body 12 of the dust removing drive transmission unit 11 through the cam crank 30 of the power branch mechanism 25 so that the end portion 87b of the upper horizontal dust removing body 6 receives an upward load. The auxiliary part 83 operates substantially in the vertical direction.

  The horizontal dust remover 6 has an end (upper horizontal dust remover transmission shaft) 86 other than the load side of the upper horizontal dust remover 6 when operated in a substantially vertical direction, and the upper horizontal dust remover 6 6 is transmitted to the upper horizontal dust removing body auxiliary portion 83.

  The operation of the upper horizontal dust removing body transmission shaft 86 transmits the operation from the operation receiving portion 88 of the upper horizontal dust removing body auxiliary portion 83, and operates the upper horizontal dust removing body auxiliary portion 83 in a substantially vertical direction.

  The operation receiving portion 88 of the upper horizontal dust removing body auxiliary portion is disposed on the upper horizontal dust removing body 6 side with respect to the support shaft 89a of the upper horizontal dust removing body auxiliary portion.

  As a result, the upper horizontal dust remover 6 is actuated upward from the power branch mechanism 25, the front end 87a of the upper horizontal dust remover 6 is pushed down, and the upper surface of the dust bag 7 is instantly hit. At the same time, the interlocked upper horizontal dust removing body auxiliary portion 83 as shown in FIG. 24b lifts the whole upward with respect to the support shaft 89a as a reference, so as to give a vibration to the dust bag 7.

  Next, when the upper horizontal dust removing portion 6 returns to its original position by the biasing by the springs 90a, 90b, etc., the upper horizontal dust removing body auxiliary that has been lifted upwards with respect to the support shaft 89a as a reference. The part 83 can hit the upper surface of the dust bag 7 when the operation receiving part 88 receives power from its own weight and the upper lateral dust removing body transmission shaft 86 as shown in FIG. 24a.

  By this series of operations, it is possible to perform dust removal by vibrating the upper surface of the dust bag 7 alternately at least twice and at two or more locations by one power transmission from the power branch mechanism 25.

  Further, in some cases, the operation receiving portion 88 of the upper horizontal dust removing body auxiliary portion 83 is disposed on the side away from the upper horizontal dust removing body 6 with respect to the support shaft 89b. By one-time power transmission, one place or more places on the upper surface of the dust bag 7 can be vibrated simultaneously.

  As shown in FIG. 3, the dust collection bag 7 has a rear side on the moving base member 201 of the moving member 200, a lower side on the bottom moving member 202, and an upper side on the upper horizontal dust removing body 6 and the upper horizontal dust removing body auxiliary portion 83. Abut. By rotating the dust removing rotator 12, the bottom moving member 202 rotatably coupled to the moving base member 201 is opposed to the biasing spring 26, and the moving base member 201 is moved back and forth, and the bottom portion. The moving member 202 is interlocked with the moving base member 201 and vibrates back and forth and also vibrates substantially vertically. Further, the power branch mechanism 25 transmits power from the protrusion 27 of the dust removing rotary body 12 and vibrates the upper horizontal dust removing body 6 and the upper horizontal dust removing body auxiliary portion 83 substantially vertically through the cam crank 30.

  The rear side of the dust bag 7 is swung back and forth by the moving base member 201, the lower side is rubbed back and forth by the bottom moving member 202 and is shaken up and down slightly, and the upper side is the upper horizontal dust remover 6 and the upper horizontal dusting It is shaken up and down by the dust removing body auxiliary part 83. Due to this vibration, dust adhering in the dust bag 7 is removed, the air permeability of the dust bag 7 is restored, and further dust absorption can be performed. In particular, on the upper side having a large influence on the dust collection performance, a large effect can be obtained by the upper horizontal dust remover and the upper horizontal dust remover auxiliary unit. By repeating this, dust can be absorbed until the inside of the dust bag 7 is filled.

  A method of attaching the biasing spring 26 will be described with reference to FIGS.

  The dust-removing frame body portion 20 of the moving base member 201 has a spring accommodating portion 36 on one side upper portion. The spring accommodating portion 36 is formed by the outer side surface of the dust removing frame body portion 20, the front side wall 37, and the inner side wall 38. The rear side of the spring accommodating portion 36 has no wall portion and is open. One support shaft protrusion 203 described above is provided outside the outer wall 38.

  In the spring accommodating portion 36, a spring support shaft projection 39 that supports the center of the urging spring 26 on the outer surface of the dust removing frame body portion 20, and left and right backlash of the urging spring 26 and a reinforcing rib for preventing falling 40.

  As shown in FIG. 27, the urging spring 26 is accommodated in the spring accommodating portion 36 and presses the urging spring end 41 against the intermediate partition wall 21. As a result, the moving base member 201 is given a rotational force in the direction of arrow P with the support shaft projection 203 as a fulcrum by the force of the biasing spring 26.

  As described above, the urging spring 26 acts so as to resist the force of pushing the moving base member 201 by the rotation of the dust removal rotary body 12. The moving member 200 performs a dust removing vibration operation by the pressing force generated by the rotation of the dust removing rotating body 12 and the force resisted by the biasing spring 26.

  The urging spring 26 can be easily assembled by inserting it into the spring accommodating portion 36 and inserting the center of the urging spring 26 into the spring support shaft projection 39. Further, the dust removing frame body portion 20 functions as the biasing spring 26 by pressing the biasing spring end 41 against the intermediate partition wall 21 by fitting the support shaft protrusion 19 into the support hole 23 of the rib 310. Therefore, it is easy to attach the dust removing frame body portion 20.

  As shown in FIG. 28, the protective filter unit 45 includes a filter support frame 46, a lattice provided with support frames 47 in vertical and horizontal directions, a holding claw 48, a protective ventilation filter 49, and a holding projection 101.

  The protective ventilation filter 49, which is separate from the filter support frame 46, is held on the filter support frame 46 by a support frame 47 and a holding claw 48.

  The protective ventilation filter 49 has a ventilation hole coarser than the dust collection bag 7, is finer than the lattice of the filter support frame 46, and has flexibility. The protective ventilation filter 49 attached to the grid of the filter support frame 46 is inserted into the holding pawl 48 at the periphery. Thus, the protective ventilation filter 49 is held by the filter support frame 46.

  As shown in FIG. 26, the dust removing frame body portion 20 has an insertion groove 50 on the lower side. The insertion groove 50 is fitted with a holding projection 101 disposed on the lower outer periphery of the filter support frame 46 of the protective filter portion 45 shown in FIG.

  Since the protective filter portion 45 can be attached and detached, the protective ventilation filter 49 can be maintained by removing the protective filter portion 45 during maintenance of the moving member 200. The dust-removing frame body portion 20 made of synthetic resin not attached with the protective filter portion 45 is easily bent, and the dust-removal frame portion 20 can be easily attached and detached.

  The protection filter unit 45 is located upstream of the internal circulation port 34. Even if the dust bag 7 is torn, the protective filter unit 45 can prevent dust from being sucked into the electric blower 8 through the internal circulation port 34.

  In the protective ventilation filter 49, the peripheral edge of the downstream side surface of the air flow is held by the holding pawl 48, and in addition, it is suppressed by the vertical lattice rib 35 adjacent to the downstream frame of the moving base member 201 and the intermediate partition wall 21. The problem that the protective ventilation filter 49 falls off from the dust-removal frame 20 and the protective filter 45 does not occur.

  As shown in FIG. 28, the protective filter portion 45 has a handle 51 that protrudes to the upper side end of the filter support frame 46. The attachment / detachment of the protective filter unit 45 is performed by grasping the handle 51.

  As shown in FIG. 3, the inner bottom portion of the dust collection chamber 3 is raised. The vacuum cleaner main body 1 was raised to provide a recess for attaching the casters 52 to the front lower surface. The center of the bottom moving member 202 was raised so as to match this elevation, and the strength was increased. As a result, there is little wasted space between the bottom moving member 202 and the fixed portion of the dust collection chamber 3, and the dust collection bag 7 swells larger in the dust collection chamber 3, thereby increasing the amount of dust collection.

  Next, the relationship of the dust removal drive transmission unit 11 will be described. As shown in FIG. 30, the dust removal drive transmission unit 11 has a support frame 73. The support frame 73 includes a rectangular frame body portion 53, a bottom plate portion 54 that covers one side of the frame body portion 53, and two rotating body supports that stand on the short side of the frame body portion 53 toward the opposite side of the bottom plate portion 54. A plate 55 is provided.

  An airtight seal 56 is provided at the peripheral edge of the two rotating body support plates 55 and the long side edge of the frame body portion 53. As shown in FIG. 31, the airtight seal 56 is formed in a continuous ring. Since the hermetic seal 56 of the continuous ring does not have a gap for joining, the sealing performance is improved, and the hermetic seal is deformed to ensure a reliable hermetic seal.

  The hermetic seal 56 is molded of synthetic resin integrally with the frame body portion 53. The hermetic seal 56 is molded of a synthetic resin softer than the frame body portion 53 so as to have a sealing function. The frame body portion 53 and the hermetic seal 56 are integrally molded by transferring the frame body portion 53 molded with a molding die to another mold and injecting a soft synthetic resin.

  Since the hermetic seal 56 does not separate from the frame body portion 73 and does not come apart, the handleability during assembly is improved. Moreover, since the hermetic seal 56 is formed of a soft synthetic resin, the sealing performance is improved.

  The dust removal rotary body 12 of the dust removal drive transmission unit 11 is rotatably supported by the two rotary body support plates 55. As shown in FIG. 32, the dust removal rotary body 12 has support shafts 74A and 76B on both ends.

  The transmission gear 13 is provided on one end side of the dust removal rotary body 12. The shaft portion 57 of the transmission gear 13 is fastened and fixed to one end side of the dust removal rotary body 12 with a screw or the like. The transmission gear 13 is located away from the end of the dust removal rotary body 12.

  A so-called one-way rotation transmission clutch 58 is provided in the dust removal rotator 12 so that rotation in one direction is transmitted and rotation in the other direction is not transmitted. The rotation of the cord reel 9 is transmitted to the dust removal rotary body 12 via the drive gear 14 of the cord reel 9 and the transmission gear 13.

  The dust removal rotator 12 is rotated when the cord is pulled out, but the dust removal rotator 12 is not rotated when the cord is wound. By doing so, the winding spring of the cord reel 9 can be reduced in size, and the cord can be pulled out lightly.

  The two rotary body support plates 55 of the support frame 73 have bearings 59A and 59B that rotatably support the support shafts 74A and 74B of the dust removal rotary body 12. The bearing 59B that rotatably supports the support shaft 74B provided with the transmission gear 13 is formed so as to penetrate therethrough.

  The bearing 59A that supports the support shaft 74A on which the transmission gear 13 is not provided is formed so that the back side is closed. Since the inner side of the bearing 59A is closed, air does not leak from the bearing 59A to the outside of the rotating body support plate 55.

  However, since the bearing 59B penetrates, the air leaks to the outside of the rotating body support plate 55. Therefore, a shaft seal 60 for sealing the gap between the bearing 59B and the support shaft 74B is provided on the outer surface side of the rotating body support plate 55. The shaft seal 60 prevents air leakage from leaking to the outside of the rotating body support plate 55 through the bearing 59B.

  As shown in FIG. 21, the cleaner body 1 has a mounting opening 61 on the bottom surface where the dust removal drive transmission unit 11 is mounted. The dust removal drive transmission unit 11 is detachably attached to the attachment opening 61 from the outside.

  As described above, the dust removal rotating body 12 and the transmission gear 13 are integrated into the support frame 73 as a unit, and the dust removal drive transmission unit 11 as a unit is attached to the mounting opening 61 of the cleaner body 1. Is called.

  The mounting opening 61 has a recess 62 where the dust removing rotator 12 and the support frame 73 are placed, and a rear chamber (where the code reel 9 and the electric blower 8 are placed) where the transmission gear 13 is placed. An opening facing the side is formed.

  As shown in FIG. 33, the recess 62 has a dust removal opening 63 on the back side. The dust removal opening 63 faces the lower end side of the moving base member 201 placed in the dust collection chamber 3.

  Further, the recess 62 has a transmission opening 64 on the side surface where the transmission gear 13 is located. The recess 62 communicates with the rear chamber side through the transmission opening 64.

  In the dust removal rotating body 12 of the dust removal drive transmission unit 11 attached to the attachment opening 61, the dust removal spring 31 on the outer peripheral side protrudes from the dust removal opening 63 to the dust collection chamber 3, and the lower end side of the moving base member 201 (the arc surface) Abutting part). The transmission gear 13 is meshed with the drive gear 13 of the cord reel 9. The shaft portion 57 of the transmission gear 13 is placed in the transmission opening 64.

  As shown in FIGS. 33 and 34, the recess 62 has a low position step 65 near the bottom of the recess 62 and a high position step 66 far from the bottom. Moreover, the hollow part 62 has joining protrusions 67 and 68 on the end side in the longitudinal direction.

  The side 56 </ b> B of the hermetic seal 56 abuts on the lower position step portion 65 of the recess 62. The side 56 </ b> A of the hermetic seal 56 abuts on the high position step portion 66 of the recess 62. A side 56 </ b> C of the hermetic seal 56 abuts on the joint protrusion 68. The side 56D of the hermetic seal 56 abuts on the joint protrusion 67.

  By the sealing of the airtight seal 56 by the contact, air is prevented from flowing between the dust collection chamber 3 and the outside of the cleaner body 1 through the dust removal opening 63. For this reason, there is no air leakage through which air flows between the dust collection chamber 3 and the outside of the cleaner body 1 through the mounting opening 61.

  The hermetic seal 56 also includes a seal where the recess 62 communicates with the rear chamber (where the code reel 9 and the electric blower 8 are placed) via the transmission opening 64. For this reason, air circulation is also cut off between the dust collection chamber 3 and the rear chamber, and no air leakage occurs.

  (A) of FIG. 34 has shown the place which carried out the cross section in the horizontal direction of the dust removal drive transmission unit with which the installation opening part 61 of the vacuum cleaner main body was mounted | worn.

  FIG. 34 (b) shows the dust removal drive transmission unit 11 removed from the mounting opening 61. A dust removal opening 63 is visible at the bottom of the recess 62. Further, although not shown, the joint protrusions 67 and 68 are located at the two rotating body support plates 55.

  The joint protrusions 67 and 68 provided so as to protrude from the inner surface of the recess 62 are narrower than the width of the hermetic seal 56. By pressing the airtight seal 56 pressed against the joint protrusions 67 and 68, the joint protrusions 67 and 68 bite into the airtight seal 56 and the airtightness is improved.

  The dust removal drive transmission unit 11 is fastened and fixed by screws screwed into screw bosses 69 and 70 provided in the cleaner body 1. The screw through holes 71 and 72 provided in the dust removal drive transmission unit 11 are provided outside the two rotating body support plates 55.

  If screw through holes are provided inside the two rotating body support plates 55, the screw through holes must be airtight. By providing the screw through holes on the outer sides of the two rotating body support plates 55, it is not necessary to provide airtightness and the configuration is simplified.

  Next, a fifth embodiment of the present invention will be described with reference to FIGS. The moving member 200 is located on the upstream side of the electric blower 8, forms a breathable plate or lattice shape, and air containing dust sucked from the suction port 600 passes through the breathable moving member 200. It is sucked into the electric blower 8.

  A filter member 350 such as a cloth, a nonwoven fabric (chemical fiber having a breathability such as a melt blown, a PTFE film, or GORE-TEX), urethane (sponge), etc., which is integral with or separate from the moving member 200 and has a breathability. By arranging it, the dust collection efficiency is improved, and at the same time, various dust such as fine dust that could not be collected by the dust bag 7, sand dust and cotton dust that spilled into the dust collection chamber by mistake was collected. When the electric vacuum cleaner main body 1 is operated, it serves to prevent dust from breaking into the electric blower 8 due to intrusion.

  Further, a filter having a deodorizing effect such as a photocatalyst is kneaded into, impregnated with, or applied to the filter member 350, so that an unpleasant odor such as ammonia passing through the dust collected in the dust bag 7 Since the air containing the air is deodorized and discharged through the electric blower 8 to the outside of the main body 1, the user can clean without worrying about the odor emitted from the exhaust during cleaning.

  Next, a sixth embodiment of the present invention will be described with reference to FIGS. 14 and 41 to 43.

  Next, airtight maintenance of the dust collection chamber will be described. As shown in FIG. 14, the lid 5 is supported by a bearing 131 of the upper case 130 so as to be openable and closable so as to cover the dust collection chamber 3, and is attached through the hermetic member 10 so as to maintain hermeticity.

  The airtight member 10 includes a plurality of protrusions 100 and a buffer part 110 formed integrally with the protrusions, and the first protrusion 100a is a dust collecting member. The first partition wall 103a formed by the first partition wall 103a and the second partition wall 103b standing in the vertical direction formed on the outer periphery of the chamber 3 is hermetically inserted.

  That is, the first protrusion 100a of the airtight member 10 is taper-fitted to the groove side surface formed by the first partition wall 103a and the groove side surface formed by the second partition wall 103b. Airtightness is ensured by pushing in 100a.

  It is desirable to use an elastic body for the airtight member 10, and as the hardness is lowered (softened), the airtight member 10 is more easily held.

  The second protrusion 100b is inserted into the second groove 102b formed by the second partition 103b and the third partition 103c, and the first protrusion 100a and the second protrusion 100b are the second partition. Thus, the airtight member 10 and the dust collecting chamber 3 are hermetically sealed by the grooves 102 formed by the partition walls and the plurality of protrusions of the airtight member 10.

  Since the first protrusion 100a and the first groove 102a are hermetically sealed by taper fitting, the second partition 103b is further connected by the first protrusion 100a and the second protrusion 100b. Even if airtight leakage occurs due to the taper fitting between the first protrusion 100a and the first groove 102a by sandwiching, the second protrusion 103a and the second protrusion 100b are connected to the second partition wall 103b. Since it is sandwiched in an airtight manner, a double sealing effect can be obtained.

  Further, by holding the second protrusion 100b in a taper fit to the second groove portion 102b formed by the second partition wall 103b and the third partition wall 103c, a higher airtight holding effect can be obtained. .

  Further, the number of partition walls is increased to the fourth and fifth, the number of grooves formed between the partition walls is increased, and accordingly, the number of the plurality of protrusions 100 formed by the airtight member 10 is increased, and the above-described fitting is performed. By increasing the configuration of the joint relationship, the airtightness of the dust collection chamber 3 and the airtight member 10 can be further improved.

  Further, a buffer portion 110 is formed integrally with the plurality of protrusions 100 of the airtight member 10, and is disposed so as to cover the partition wall (the third partition wall 103c in the figure) located on the outermost side of the dust collection chamber 3, It protects the main body against external impacts and protects home furniture and buildings.

  Furthermore, the other end 106 of the buffer part 110 securely fixes the groove part 102 constituted by the partition wall of the dust collecting chamber 3 and the part that is kept airtight by the taper fitting of the airtight member 10 without using another part. For this purpose, a locking projection 107 is provided in the vertical direction on the outer peripheral portion of the dust collecting chamber 3, and an engagement projection 106 is provided on the airtight member 10 in order to engage with this.

  The locking projection 107 securely fixes the airtight member 10 by forming a continuous partition along the outer periphery of the dust collecting chamber 3 and disposing the intermittent projections uniformly or non-uniformly.

  The engagement protrusion 107 can further enhance the engagement of the airtight member 10 by combining the partition wall formed continuously with the partition wall formed in the vertical direction intermittently with respect to the dust collection chamber 3.

  Further, the engagement protrusions 106 of the airtight member 10 are formed on the end face of the buffer part 110 and are formed so as to be substantially opposed to the plurality of protrusions 100 of the airtight member 10, and the engagement protrusions 106 are formed continuously or discontinuously. In addition, the airtight member 10 is prevented from peeling from the partition wall 103 due to external impact and user's accidental operation, and the airtightness is maintained.

  The partition wall (the third partition wall 103c in the figure) located on the outermost side of the dust collecting chamber 3 has the second protrusion 100b fitted inside and the locking protrusion 107 and the engagement protrusion 106 fitted. At this time, the buffer part 110 and the airtight member 10 themselves are separated from the dust collecting chamber 3 to cause airtight leakage by forming a hook structure. During the operation of the main body, the inside of the dust collection chamber 3 becomes negative pressure, so that the airtight rib 108 of the lid 5 works in the direction of pressing the airtight member, and the dust collection chamber 3 and the lid 5 can be kept airtight.

  Further, during operation, the plurality of protrusions 100 of the airtight member 10 work in the direction in which they are pressed by the grooves 102, and can be prevented from coming off at the same time as airtightness can be taken. In order to facilitate airtightness in the dust collection chamber 3, the portion of the lid 5 of the airtight member 10 that is in contact with the airtight rib 108 is formed into a lip shape 105, so that the airtightness is further increased when the dust collection chamber 3 becomes negative. I can take it. By making the material of the airtight member a softer elastic member, it becomes easier to take airtightness. As the above-mentioned precondition, the airtight rib 108 of the lid 5 and the lip shape 105 of the airtight member 10 need to interfere or contact uniformly. It is desirable that the end face of the lip shape 105 is inside the thickness of the outer peripheral end face 109 of the lid 5.

  If it is inside the thickness of the outer peripheral end surface 109 of the lid 5, the appearance is also beautiful, and the sink 5 sinks into the dust collection chamber due to negative pressure in the dust collection chamber 3 during operation of the main body. Thus, when the lip shape 105 is pushed by the airtight rib 108 of the lid 5, if the end face of the lip shape 105 protrudes from the outer peripheral end face 109 of the lid 5, not only the appearance is impaired, but also the dust collecting chamber 3 Before the airtight rib 108 for taking the airtightness presses the lip shape 105 of the airtight member 10 to achieve the airtightness, the outer peripheral end surface 109 of the lid 5 pushes the lip shape 105, and the airtightness leaks from that portion. there is a possibility.

  For this reason, the end surface of the lip shape 105 is formed on the inner side of the thickness of the outer peripheral end surface 109 of the lid body 5 or the edge distance between the airtight rib 108 and the outer peripheral end surface 109 of the lid body 5 is sufficiently taken to It is necessary to configure the lip shape 105 at a position where the end surface 109 is not pushed.

  Next, the attachment / detachment of the dust bag 7 (paper pack) or dust collection case (not shown) will be described. Considering the take-out property of the dust bag (paper pack) 7 and dust case (not shown) placed in the dust chamber 3, especially in the case of the dust case, the possibility of frequent trashing work Therefore, when the inner side surface 111 of the airtight member 10 is located on the same surface as the inner side surface 112 of the first partition wall 103a of the dust collecting chamber 3 or on the outer side, the airtight member 10 (elasticity) having a large frictional resistance is provided. Do not attach the dust collecting bag (paper pack) 7 or the dust collecting case (not shown) directly to the member, and do not press the inside of the airtight member 10 without being pressed inside. Therefore, it is possible to attach and detach the dust collection bag (paper pack) 7 and the dust collection case (not shown) with a light force, and it is possible to make it easy to throw away garbage.

  Due to the structure where the inner wall 103 of the dust collection chamber 3 and the airtight member 10 are flush with each other, the take-out property of the dust collection bag 7 is further improved, and the opening of the dust collection chamber 3 when the dust is thrown away (when the disposable dust collection bag 7 is taken out). The moving member 200 moving in the direction acts more effectively, and the load on the user can be minimized.

  Next, a seventh embodiment of the present invention will be described with reference to FIGS. The moving member 200 and the moving base member 201 are movably disposed when the engaging protrusion 204 of the moving member 200 engages with the engaging hole 206 of the moving base member 201. When the engaging protrusion 204 of the moving member 200 is a hemisphere as shown in FIG. 44, the engaging hole 206 of the moving base member 201 is configured as an ellipse or the like as shown in FIG. At that time, when the force in the opening direction is released at the same time as the movement in the opening direction is stopped, and the movement in the opening direction is suppressed at the same time (when the user releases the force in the opening direction) After the 7 is removed from the dust collecting chamber 3, it returns to the position before movement by its own weight or movable means such as a tension spring as shown in FIG. 45. As a result, when the dust bag 7 is taken out and a new dust bag 7 (used bag-type filter) is set on the filter guide 73 of the dust chamber 3 again, it is easy to attach and clean next time. When the dust bag 7 is taken out, the effect of the moving member 200 can be sufficiently exerted.

  Next, an eighth embodiment of the present invention will be described with reference to FIG.

  The moving member 200 can sufficiently withstand the load in the opening direction of the dust collecting chamber 3 to the extent that the dust collecting bag 7 filled with dust is pulled out. However, the load other than the opening direction is not limited to this, and if the hose insertion port 4 is moved so as to be inclined, the user can easily remove it, and the filter member 350 formed integrally or separately with the moving member 200. The dirt adhering to the dust can be removed by washing or the like, and fine dust including sand accumulated at the bottom of the dust collecting chamber 3 can be easily removed by removing the bottom moving member 202 at the same time.

  Next, a ninth embodiment of the present invention will be described.

  Since the material of the moving member 200 is made of lubricity and is made of a highly slidable material such as POM, Duracon, or nylon, the frictional resistance during movement can be kept small. If a highly slidable material such as POM, Duracon, or nylon cannot be used due to the shape and configuration of the moving member, the material of the part having a surface that slides with the moving member should be a highly slidable material. The friction can be reduced, and the load on the user can be reduced by reducing the mechanical loss.

  Next, a tenth embodiment of the present invention will be described with reference to FIG.

The engaging protrusion 204 formed on the outer surface of the moving member is provided with at least one or more protruding portions that are substantially symmetrical in the outer left and right directions in substantially the same direction with respect to the moving direction. When pulled out to the opening side, it can be pulled out substantially in parallel with a good balance.
In addition, when the load on the opening side of the dust collection chamber 3 is removed, a plurality of or continuous projections 204 are formed approximately symmetrically so that the track can be returned in the same orbit as that drawn to the position before the movement. As a result, smooth movement with few failures is obtained. Since the trajectory before and after the movement is the same, the moving member 200 can be operated without any problem even if some dust or fine dust is caught in the sliding part or the engaging part.
