The dust collection unit 65 includes a coarse dust collection chamber 71 that accumulates relatively heavy dust among the dust separated by the separation unit 64, and a filter chamber 72 that accommodates the filter unit 69.

The relatively heavy dust separated by the first separation portion 68 is called coarse dust. The relatively light dust separated by the filter unit 69 is called fine dust. The coarse dust collecting chamber 71 and the filter chamber 72 are collectively referred to as a dust collecting chamber 73.

Dust-containing air flowing from the body connection port 18 to the primary dust container 13 is separated into a coarse dust in the first separation unit 68 other than the (air containing fine dust). The separated coarse dust is accumulated in the coarse dust collection chamber 71. The air containing fine dust separated by the first separation portion 68 flows into the filter chamber 72. The air flowing into the coarse dust collecting chamber 71 also flows into the filter chamber 72. The air containing fine dust that has flowed into the filter chamber 72 is separated into fine dust and air by the filter unit 69. The separated fine dust is captured by the filter unit 69 and accumulated in the filter chamber 72. The clean air that has passed through the filter unit 69 is sucked into the primary electric blower 15 through the air connection passage 66.

The first separation portion 68 includes a nozzle portion 75 connected to the main body connection port 18, a frusto-conical primary filter frame 76 including the nozzle portion 75, and a first mesh filter 77.

The nozzle portion 75 extends from the suction port 78 a of the container body 78 corresponding to the outer shell of the primary dust container 13 into the container body 78.

The primary filter frame 76 is provided on the inner surface of the container body 78. The primary filter frame 76 tapers along the center line of the main body connection port 18, that is, substantially along the center line C of the cleaner body 7 in a state where the primary dust container 13 is attached to the main body case 11. There is. The large diameter bottom portion is in contact with the inner surface of the container body 78, and the small diameter bottom portion has a coarse dust discharge port 79 connected to the coarse dust collection chamber 71 of the dust collection unit 65. The diameter of the large diameter bottom portion is larger than the opening diameter of the suction port 78a. Center line of the rough dust discharge port 79 is substantially along the center line of the suction port 78a, and substantially along the center line of the body connection port 18.

The first mesh filter 77 is provided on the side surface of the primary filter frame 76. A relay air passage 81 connected to the filter chamber 72 is partitioned outside the first mesh filter 77.

The first separating portion 68 has a negative pressure due to the flow of air sucked into the primary electric blower 15 through the first mesh filter 77 and the flow of air sucked into the primary electric blower 15 through the coarse dust discharge port 79.

The coarse dust collecting chamber 71 accumulates relatively heavy dust separated by the first separating portion 68. The coarse dust collection chamber 71 is a part of the air path of the air sucked into the primary electric blower 15. The coarse dust collection chamber 71 is connected to the coarse dust discharge port 79 of the first separation portion 68. The coarse dust collection chamber 71 is also connected to the filter chamber 72. The coarse dust collecting chamber 71 is disposed on the center line of the main body connection port 18, that is, substantially on the center line C of the cleaner body 7. Further, crude dust dust collecting chamber 71, a direction away from the primary electric blower 15, in other words, has been extended in a direction approaching the filter unit 69. Between the filter chamber 72 to the extension portion and the filter portion 69 is housed, the partition wall 83 having a plurality of coarse dust dust collecting chamber outlet 82 is provided. At the coarse dust collecting chamber outlet 82 of the partition wall 83, a second mesh filter 84 is provided. The second mesh filter 84 prevents the coarse dust from flowing out from the coarse dust collection chamber 71 to the filter chamber 72. Further, the second mesh filter 84 compresses the dust accumulated in the coarse dust collection chamber 71 by the flow of air passing therethrough. The second mesh filter 84 has substantially the same mesh as the first mesh filter 77. Temporarily, fine dust not separated by the first separation portion 68 and flowing into the coarse dust collecting chamber 71 passes through the second mesh filter 84 and flows into the filter chamber 72 or a filter in the coarse dust collecting chamber 71 It is captured by coarse dust compressed as follows.

The filter section 69 filters and separates dust, particularly fine dust passing through the first separation section 68, from air (dust-containing air) containing dust that is absorbed by the negative pressure generated by the primary electric blower 15. Filter unit 69 includes a pair of filters 86 and 87 facing a secondary filter frame 88 for supporting and maintaining the shape of a pair of filters 86 and 87, the.

The pair of filters 86, 87 have their downstream surfaces face each other. The respective filters 86, 87 filter and separate dust from dusty air drawn into the primary dust container 13. Network eye filters 86 and 87, finer than the second mesh filter 84 of the first mesh filter 77, and Sochiri dust collecting chamber 71 of the first separation unit 68. The filters 86, 87 are, for example, non-woven fabrics. The fine dust trapped in the filter 86 and 87, the dust is contained as possible through the first mesh filter 77 and the second mesh filter 84,.

One of the filters 86, 87 (filter 86) is directly exposed to the air flowing into the filter chamber 72, and the other (filter 87) of the filters 86, 87 wraps around one of the filters 86, 87 (filter 86). Exposed to the air. That is, the filter 86 faces the relay air passage 81 connecting the first separation portion 68 and the filter portion 69, and faces the coarse dust collecting chamber outlet 82 connecting the coarse dust collecting chamber 71 and the filter chamber 72. . The filter 87 is hidden by the filter 86 and disposed at a position where it can not be seen from the relay air passage 81 and the coarse dust collection chamber outlet 82.

A pair of filters 86 and 87 is a pleated filter having substantially the same size (interval), and the folds of the same depth ( ridge 86a, 87a).

The filter 86 facing the relay air duct 81 and Sochiri dust collecting chamber outlet 82 may have a wide and shallow fold as compared to the filter 87. Since the filter 86 faces the relay air passage 81 and the coarse dust collection chamber outlet 82, the dust passing through the first separation portion 68 and the dust flowing out of the coarse dust collection chamber 71, that is, the fine dust are first filtered Spray on 86 Then, the filter 86 catches fine dust and causes clogging gradually. As the filter 86 is clogged, fine dust sprayed from the relay air passage 81 and the coarse dust collection chamber outlet 82 to the filter 86 comes to the filter 87. Then, clogging of the filter 87 also starts. That is, the filter 86 is more likely to be clogged than the filter 87. In other words, dust tends to adhere to the filter 86 compared to the filter 87. Thus, by leaving shallow wider than the folds of the filter 86 to the filter 87 can be easily removing dust from easily filter 86 more adhesion dust.

The filters 86 and 87 may have a film of polytetrafluoroethylene (PTFE, so-called Teflon (registered trademark)) on the upstream surface so as to easily remove attached dust. Further, only the filter 86 which is easily clogged as compared to the filter 87 may have a polytetrafluoroethylene film on the upstream surface.

The filters 86 and 87 have ridge lines 86 a and 87 a (folds) extending in the vertical direction (vertical direction) in the storage form of the electric cleaning device 1. In other words, the ridge lines 86 a and 87 a of the filters 86 and 87 extend in the front-rear direction of the cleaner body 7. The filters 86 and 87 are open at the end face intersecting the fold.

Incidentally, the open end face of the filter 86 and 87, ventilation holes (not shown between may be a zig-zag shape, the adjacent crests having peaks and valleys along the edge shapes of the filter 86 and 87 ) May be interposed.

The secondary filter frame 88 supports the pair of filters 86, 87 facing each other and spaced apart. A space defined by the secondary filter frame 88 and the pair of filters 86 and 87 corresponds to an air passage on the downstream side of the filter unit 69. The internal space of the filter unit 69 is connected to the communication air passage 66. The secondary filter frame 88 is disposed on both sides of the filter 86 and has a secondary filter outlet 89 connected to the communication air passage 66. The secondary filter outlet 89 allows the air that has passed through the filters 86 and 87 to flow out to the communication air passage 66.

The filter chamber 72 functions as a fine dust collecting chamber for accumulating fine dust captured by the filter section 69 by filtration separation. Fine dust passing through the first mesh filter 77 and the second mesh filter 84 is captured by the finer mesh pair of filters 86, 87 and accumulated in the filter chamber 72. That is, the dust collection chamber 73 (the coarse dust collection chamber 71 and the filter chamber 72) is disposed upstream of the filters 86 and 87.

The filter chamber 72 is a part of an air path of air sucked into the primary motor blower 15. The filter chamber 72 is connected to the relay air passage 81. The filter chamber 72 is also connected to the coarse dust collecting chamber 71.

The connection air passage 66 is a plurality of air passages 66 a and 66 b for guiding the air flowing out of the separation unit 64 to the primary electric blower 15. That is, the communication air path 66 is branched into a plurality and reaches the primary electric blower 15. The connecting air path 66 is divided into, for example, two air paths 66a and 66b. A plurality of, for example, two air passages 66 a and 66 b sandwich an air inlet 78 a for introducing air to the separation unit 64. The two air passages 66a and 66b have substantially equal air passage cross-sectional areas S. The two air paths 66a and 66b have a plane-symmetrical shape with respect to the plane including the rotation center line of the fan of the primary motor blower 15. The two air passages 66a, 66b gather at the end of the communication air passage 66 connected to the primary electric blower 15 and merge. In other words, the two air passages 66 a and 66 b are connected to the primary electric blower 15 via the collective air passage 66 c of the communication air passage 66. Note that the communication air path 66 may be branched into three or more.

The relatively large mass of coarse dust in the dust-containing air flowing from the nozzle 75 to the first separation portion 68 is transferred straight from the nozzle 75 to the coarse dust discharge port 79 by the inertial force and sent to the coarse dust collection chamber 71 Be Dust (coarse dust) flowing from the coarse dust discharge port 79 into the coarse dust collection chamber 71 is accumulated in the coarse dust collection chamber 71. On the other hand, among the dust-containing air flowing into the first separation portion 68 from the nozzle portion 75, fine dust and air having a relatively small mass radially spread from the nozzle portion 75 and provided on the side surface of the primary filter frame 76 It passes through the mesh filter 77 and flows into the filter chamber 72 through the relay air passage 81. Along with the dust (coarse dust) flowing from the coarse dust discharge port 79 into the coarse dust collection chamber 71, part of the air also flows into the coarse dust collection chamber 71. The air flowing into the coarse dust collection chamber 71 passes through the second mesh filter 84 and flows into the filter chamber 72. Fine dust contained in the air flowing through the first mesh filter 77 or the second mesh filter 84 and flowing into the filter chamber 72 is separated by filtration in the filter section 69 and captured on the surfaces of the pair of filters 86, 87. The clean air passing through the filters 86, 87 is drawn into the primary motor blower 15 through the communication air passage 66. At this time, the clean air is temporarily divided into a plurality of air passages 66a and 66b, collected and sucked into the primary electric blower 15.

The container body 78 divides the dust collection chamber 73, that is, the coarse dust collection chamber 71 and the filter chamber 72. The first separation portion 68 and the connection air passage 66 in the separation portion 64 are disposed between the filter portion 69 and the primary electric blower 15 and are juxtaposed to each other.

The container body 78 defines the dust collection chamber 73, that is, the coarse dust collection chamber 71 and the filter chamber 72. Further, the container body 78 defines a machine room 98 that accommodates the power transmission mechanism 96. The container body 78 is cylindrical as a whole. The container main body 78 is mounted on the area A1 with the cylindrical center line directed in the width direction of the main body case 11.

The disposal port 91 and the intake port 93 are provided on the side surface of the container body 78. The intake lid 94 and the disposal lid 92 are opened and closed collectively. The waste port 91 is closed by the waste lid 92 except when moving dust from the cleaner body 7 to the station 2. The intake port 93 is closed by the intake lid 94 except when moving dust from the cleaner body 7 to the station 2.

The disposal port 91 discards the dust accumulated in the primary dust container 13 together with the air introduced from the intake port 93. The disposal port 91 is disposed at the rear end of the main body case 11. The disposal port 91 is disposed at a portion where the station 2 and the cleaner body 7 are in contact with each other. That is, the disposal port 91 is disposed on the back of the main body case 11. The back surface of the main body case 11 is located at the lowermost end of the main body case 11 in the storage mode (FIG. 2) of the electric cleaning device 1. The disposal port 91 is disposed below the filter portion 69 in the storage form of the electric cleaning device 1.

At the rear end portion of the main body case 11, a main body case discarding port 99 larger than the discarding port 91 is provided. The main body case disposal port 99 allows the dust transfer pipe 43 of the station 2 to pass through in the storage form of the electric cleaning device 1 and connects the inlet of the dust transport pipe 43 to the disposal port 91.

The disposal port 91 includes a coarse dust disposal port 101 connected to the coarse dust collection chamber 71 and a fine dust disposal port 102 connected to the filter chamber 72. The coarse dust disposal port 101 and the fine dust disposal port 102 are aligned in the width direction of the main body case 11, that is, in the center line direction of the container main body 78. The coarse dust collection chamber 71 and the filter chamber 72 share the partition wall 83 in the vicinity of the disposal port 91 and are adjacent to each other.

The disposal lid 92 and the intake lid 94 are part of the side surface of the container body 78. The intake lid 94 is provided so as to be reciprocally movable in the circumferential direction of the cylindrical container body 78. The disposal lid 92 is supported by the container body 78 by a hinge mechanism (not shown). The disposal lid 92 opens and closes the coarse dust disposal port 101 and the fine dust disposal port 102 collectively. When the disposal lid 92 is opened, the coarse dust disposal port 101 and the fine dust disposal port 102 are collectively connected to the dust transfer pipe 43.

The air inlet 93 is an inlet for taking air into the filter chamber 72 from the outside of the vacuum cleaner body 7 or from inside the air case which is in the body case 11 and connected to the primary electric blower 15. The suction port 93 is a suction port that generates a flow of air when moving dust from the cleaner body 7 to the station 2.

The intake port 93 is disposed at a location farthest from the disposal port 91 when viewed in the circumferential direction of the container body 78, that is, at a location 180 degrees away, in other words, at a line symmetrical position with the center line of the container body 78 as a symmetry line. .

Further, the intake port 93 is disposed in the air path upstream of the filters 86 and 87 (upstream of the flow generated by the primary electric blower 15).

The air introduced from the intake port 93 causes the fine dust filtered by the filters 86 and 87 and the coarse dust accumulated in the primary dust container 13 to flow out collectively from the waste port 91. When a negative pressure is applied to the filter chamber 72 from the dust transfer pipe 43 through the fine dust disposal port 102, the intake port 93 blows air on the filters 86 and 87. The air blown to the filters 86 and 87 blows off the dust trapped on the surfaces of the filters 86 and 87 and guides the dust to the fine dust disposal port 102. The filters 86, 87 have ridge lines 86a, 87a extending in the vertical direction during dust removal, that is, in the storage form of the electric cleaning device 1, and the end face intersecting the fold is open. For this reason, the air blown onto the filters 86, 87 can easily flow along the folds, and the separated fine dust can be made to flow out smoothly from the ends of the folds.

At this time, a negative pressure acts on the coarse dust collection chamber 71 from the dust transfer pipe 43 through the coarse dust disposal port 101. Crude dust dust collecting chamber 71, in order to direct the filter chamber 72, also through a first isolation portion 68 is connected indirectly to the filter chamber 72, part of the air flowing from the intake port 93, crude dust It also flows into the dust collection chamber 71. The air flowing into the coarse dust collection chamber 71 causes the coarse dust accumulated in the coarse dust collection chamber 71 to flow out from the coarse dust disposal port 101 (discard).

The air intake 93 according to the present embodiment is provided in the container main body 78 of the primary dust container 13 and disposed in the air passage on the upstream side of the filters 86 and 87. The air flow path may be provided on the downstream side of the flow generated by the primary electric blower 15 (intake port 93 and intake cover 94 shown by a two-dot chain line in FIG. 6). In this case, the intake port 93 leads to the air path from the filters 86 and 87 to the primary motor blower 15, for example, the communication air path 66.

The secondary battery 17 surrounds the coarse dust collecting chamber 71. That is, the plurality of unit cells 17 a included in the secondary battery 17 are disposed along the inner surface of the cylindrical rear half of the main body case 11 and surround the coarse dust collecting chamber 71.

The dust compression mechanism 97 is provided in the coarse dust collection chamber 71. The dust compression mechanism 97, for example, sandwiches the coarse dust with one of the wall surfaces of the coarse dust collection chamber 71, compresses the coarse dust, and reduces the volume.

Next, the dust removal mechanism 95 of the vacuum cleaner 3 which concerns on this embodiment is demonstrated.

FIG. 8 is a perspective view of the dust removing mechanism of the vacuum cleaner according to the embodiment of the present invention.

As shown in FIG. 8, the dust removing mechanism 95 of the vacuum cleaner 3 according to the present embodiment is disposed between the pair of filters 86 and 87. In other words, the dust removal mechanism 95 is disposed in the internal space of the filter unit 69. The dust removal mechanism 95 collectively removes dust from the pair of filters 86 and 87.

The dust removing mechanism 95 includes a driven portion 106 including a plurality of racks 105 connected, and a gear 107 for meshing the plurality of racks 105 sequentially while rotating in one direction and moving the driven portion 106 along a predetermined track. And.

The driven unit 106 includes a frame 108 that integrally connects the plurality of racks 105 in addition to the rack 105, a mechanism that defines the moving direction of the rack 105, such as a slider 109, and dust collectors 111 that contact the respective filters 86 and 87. And.

The plurality of racks 105 in the present embodiment are a pair of racks 105 arranged in parallel. The driven portion 106 reciprocates by alternately meshing the gear 107 with the pair of racks 105.

The frame 108 connects the respective ends of the pair of racks 105. The pair of racks 105 and the frame 108 draw a rectangle as a whole.

The slider 109 has a hole 105 a of the rack 105 and a rod-like rail 112 inserted through the hole 105 a and fixed to the secondary filter frame 88 of the filter portion 69. The slider 109 may have, for example, an elongated hole provided in the frame 108 or the rack 105, and a pin member such as a screw or a rivet inserted into the elongated hole and fixed to the secondary filter frame 88. .

The gear 107 is disposed at the center of the filter unit 69. In other words, the gear 107 is sandwiched between the pair of filters 86 and 87 and disposed at the center of the projection plane of the filters 86 and 87.

The teeth 107a of the gear 107 are partially provided. In other words, the gear 107 is partially devoid of teeth 107a. The teeth 107 a of the gear 107 sequentially mesh with the plurality of racks 105 in the process of one rotation of the gear 107. The teeth 107 a of the gear 107 are limited to a range (the number of teeth) in which the two or more racks 105 do not mesh simultaneously.

More specifically, the teeth 105 b of the rack 105 are one more than the teeth 107 a of the gear 107. That is, the number of grooves between the teeth 105 b and the teeth 105 b of the rack 105 is the same as the number of teeth 107 a of the gear 107. For example, there are four teeth 107a of the gear 107 and five teeth 105b of the rack 105. The distance from the bottom of the groove of the pair of racks 105 to the bottom of the groove is slightly larger than the outermost diameter of the gear 107. This difference (clearance) facilitates engagement and disengagement of the teeth 107 a of the gear 107 and the teeth 105 b of the rack 105.

The tooth 107a meshes with one of the racks 105 to move the driven portion 106 in the forward path while the gear 107 having the tooth 107a partially rotates a half. When the rotation of the gear 107 advances (advances about 180 degrees), the teeth 107a come out of one rack 105, mesh with the other rack 105, and move the driven portion 106 in the return path. The gear 107 may have a period in which the teeth 107 a are not temporarily engaged with any of the racks 105 between the forward path and the return path of the driven portion 106.

The dust removing mechanism 95 having three or more racks 105 may include a mechanism other than the slider 109 for defining the moving direction of the rack 105, and a gear 107 having teeth all around. The dust removing mechanism 95 having three or more racks 105 may cause the gear 107 to rotate one or more times when making the driven portion 106 make one round on the track.

Next, the power transmission mechanism 96 of the vacuum cleaner 3 which concerns on this embodiment is demonstrated.

9 to 12 are views of a power transmission mechanism of a vacuum cleaner according to an embodiment of the present invention.

FIGS. 9 and 11 show the power transmission mechanism 96 in which the disposal lid 92 and the intake lid 94 are closed. 10 and 12 show the power transmission mechanism 96 in which the disposal lid 92 and the intake lid 94 are open. Moreover, the power transmission mechanism 96 which abbreviate | omitted the 2nd gearwheel 122 is shown by FIG. 11 and FIG.

In addition to FIGS. 3 and 5, as shown in FIGS. 9 to 12, the power transmission mechanism 96 of the vacuum cleaner 3 according to the present embodiment, the dust removing mechanism 95 from the station 2, discard the lid 92 and the intake cover 94, The dust removing mechanism 95, the waste lid 92, and the intake lid 94 are distributed and transmitted. The dust removing mechanism 95, the discard lid 92, and the intake lid 94, which obtain the driving force from the station 2 via the power transmission mechanism 96, are collectively referred to as a driven mechanism 114. The follower mechanism 114 uses the electric vacuum cleaner 3 in a state where it is possible to transfer dust from the primary dust container 13 of the vacuum cleaner 3 to the secondary dust container 49 of the station 2 using the driving force from the station 2. Change the state to the state that you can.

The power transmission mechanism 96 includes a coupling half 115, the first transmission mechanism 117 for transmitting the driving force from the coupling halves 115 to dust removing mechanism 95, the second transmission for transmitting the driving force from the coupling halves 115 to waste cap 92 A mechanism 118 and a third transmission mechanism 119 for transmitting a driving force from the joint half 115 to the intake lid 94 are provided.

The power transmission mechanism 96 also distributes the driving force received from the station 2 to the dust compression mechanism 97.

The joint half body 115 is a part of a shaft joint 120 that transmits rotational driving force. The fitting half 115 is connected to the fitting half 116 of the station 2.

The first transmission mechanism 117 always transmits the driving force input to the joint half 115 to the gear 107 of the dust removal mechanism 95. The first transmission mechanism 117 simply transmits the rotational driving force input to the joint half 115 to rotate the gear 107. That is, the first transmission mechanism 117 reverses the gear 107 if the joint half 115 is normal rotating, and rotates the gear 107 forward if the joint half 115 is reverse.

The first transmission mechanism 117 includes a first gear 121 that rotates integrally with the joint half 115, that is, a rotary integral, and a large diameter second gear 122 engaged with the first gear 121. The second gear 122 penetrates the secondary filter frame 88 of the filter section 69, and is rotatably supported by the gear 107 of the dust removing mechanism 95 by a shaft 107b (FIG. 3) that is integral with the rotation. In other words, the second gear 122 and the gear 107 of the dust removing mechanism 95 are integrally rotatable. Since the larger second gear 122 in comparison with the first gear 121, Play the filter 86 and 87, the smaller the output dust removal mechanism 95 to operate with or deforming the motor (to be described later stations second drive source 149 Can be driven by

The second transmission mechanism 118 opens and closes the disposal lid 92 by the driving force input to the joint half 115. The third transmission mechanism 119 opens and closes the intake lid 94 by the driving force input to the joint half 115. The intake lid 94 and the disposal lid 92 are simultaneously opened and closed. In other words, when the second transmission mechanism 118 opens the disposal lid 92, the third transmission mechanism 119 also opens the suction lid 94. Also, when the second transmission mechanism 118 closes the disposal lid 92, the third transmission mechanism 119 also closes the suction lid 94.

The third transmission mechanism 119 comprises: a first gear 121 shared with the first transmission mechanism 117; a lever portion 123 having teeth 123a arranged in an arc and meshed with the first gear 121; A guide portion 124 for guiding and a pair of stoppers 125 for defining (regulating) the swing range of the lever portion 123 are provided.

The lever portion 123 has a swing center that coincides with the rotation center of the second gear 122. That is, the lever portion 123 is supported together with the second gear 122 by the shaft that rotatably supports the second gear 122. The lever portion 123 is directly connected to the intake lid 94.

The guide portion 124 includes a groove 126 provided in the container body 78, and a guide plate 127 disposed in the groove 126. The groove 126 extends in an arc shape in accordance with the swinging trajectory of the lever portion 123. The guide plate 127 is integrated with the lever portion 123.

The stopper 125 defines (regulates) the swing range of the lever portion 123 in accordance with the fully closed position and the fully open position of the discard lid 92 and the intake lid 94.

The second transmission mechanism 118 includes a first gear 121 shared with the first transmission mechanism 117 and the third transmission mechanism 119, a lever portion 123 shared with the third transmission mechanism 119, a guide portion 124, and a stopper 125, and a lever portion It includes a slider 128 for converting the swinging motion of 123 into a reciprocating motion and transmitting it to the waste lid 92, and a waste lid closing spring 129 for generating a spring force for fully closing the waste lid 92. The slider 128 pushes against the spring force of the discard lid closing spring 129 to open the discard lid 92. In addition, the slider 128 closes the discarding lid 92 using the spring force of the discarding lid closing spring 129.

Here, the power transmission mechanism 96 transmits the driving force from the station 2 to the dust removing mechanism 95 for an appropriate period, while the dust removing mechanism 95 is in operation after the discard lid 92 and the intake lid 94 are fully opened or fully closed. The power transmission from the station 2 to the waste lid 92 and the intake lid 94 is shut off (margined) even within an appropriate period of time.

That is, the second transmission mechanism 118 cuts off the transmission of the driving force from the joint half 115 to the disposal lid 92 when the disposal lid 92 is fully opened or fully closed. In addition, the third transmission mechanism 119 blocks the transmission of the driving force from the joint half 115 to the intake lid 94 when the intake lid 94 is fully opened or fully closed.

Specifically, the second transmission mechanism 118 and the third transmission mechanism 119 release the meshing between the teeth 123a of the lever portion 123 and the first gear 121 when the disposal lid 92 and the intake lid 94 are fully opened or fully closed. Do. That is, the teeth 123a arranged in a circular arc shape, when discarded lid 92 and the intake cover 94 that fully open or fully closed, (is limited) to have provided a range exiting from the first gear 121.

When the disposal lid 92 is fully closed or fully opened, the teeth 123a of the lever portion 123 can not resist the disposal lid 92, which is prevented from moving, and comes out of the first gear 121 to interrupt the transmission of driving force (torque). When the intake lid 94 is fully closed or fully opened, the teeth 123a of the lever portion 123 get out of the first gear 121 and interrupt the transmission of driving force (torque).

The power transmission mechanism 96 is provided with a drive source, such as a return spring 131, which promotes smooth meshing of the teeth 123a of the lever portion 123 and the first gear 121 when meshing is restored. The return spring 131 is crushed when the disposal lid 92 and the intake lid 94 are fully opened or fully closed, and stores energy. Further, when starting to open or close the disposal lid 92 and the intake lid 94, the return spring 131 consumes energy and pushes back the lever portion 123, and the teeth 123a of the lever portion 123 bite with the first gear 121. Help the match come back.

In addition, it is preferable that the disposal lid 92 and the intake lid 94 maintain a fully open state while the dust removal mechanism 95 is operated for an appropriate period to remove dust from the filters 86 and 87. If the dust removal mechanism 95 is reciprocated by switching forward and reverse rotation of the motor (drive source 149 of the station 2 described later), the discard lid 92 and the intake lid 94 switch between forward rotation and reverse rotation of the motor. It is not preferable because it will open and close each time. Therefore, the dust removal mechanism 95 according to the present embodiment has a configuration in which the driven portion 106 can be reciprocated by the gear 107 rotating in one direction.

Next, the wheel 12 of the cleaner body 7 and the handle 14 of the cleaner body 7 according to the embodiment of the present invention will be described.

The sixth contactor 134 f and the fourth contactor 134 d of the base portion 133 sandwich the side wall 12 d of the wheel 12. The sixth contactor 134 f prevents the wheel 12 from coming out of the base portion 133 in the direction of the center line of rotation. In other words, the fourth trochanter 134d and the sixth trochanter 134f restrain the position of the wheel 12 in the rotation center line direction. The third trochanter 134c, the fourth trochanter 134d, and the sixth trochanter 134f restrain the positions of the base 133 and the wheels 12 in the direction of the rotation center line.

The base support 135 is annular like the base 133. The base holding body 135 is fixed to the main body case 11. The base holding body 135 has a flange portion 135a which enters the inner periphery of the base portion 133 and is in contact with the plurality of fifth rolling elements 134e.

The joint half 116 protrudes from the bulging portion 47 of the station 2 and is connected to the joint half 115. The joint half 116 protrudes in the width direction of the cleaner body 7 from the bulging portion 47 disposed on the side of the cleaner body 7 and is connected to the joint half 115. In other words, when disconnecting the cleaner body 7 from the station 2 and when returning the cleaner body 7 to the station 2, the connector 156 moves in a direction in which the cleaner body 7 moves, that is, a direction intersecting with the vertical direction. The half joint 116 is made to project from the bulging portion 47 to connect the shaft joint 120. That is, the moving direction of the vacuum cleaner 3 at the time of attaching the vacuum cleaner 3 to the station 2 crosses the direction in which the connector 156 moves between the retracted position and the connecting position. Therefore, the connector 156 can prevent, for example, dust from intruding into the station 2 from the gap between the bulging portion 47 and the joint half body 116, and can ensure good operation of the power transmission mechanism 151.

The joint half 116 projects from the bulging portion 47 in the width direction of the cleaner main body 7 and is connected to the joint half 115, and is also provided to be protruded from the connection guide portion 148. When 7 is connected, it may be connected to the joint half 115 at the same time (in FIG. 21, the joint half 116 of a two-dot chain line). Further, the joint halves 116 is disposed dust collection unit 42 may be one that is connected to the coupling halves 115 projects forward of the station 2 (in FIG. 21, the joint halves of a two-dot chain line 116 ).

The joint cutting spring 157 pulls the joint half 116 in the direction of disconnecting the shaft joint 120, that is, in the direction of pulling away from the joint half 115. In other words, the joint cutting spring 157 pulls the joint half 116 in the direction to be buried in the bulging portion 47.

The cam mechanism 158 is provided on the station 2 side. The cam mechanism 158 is a so-called end face cam. The cam mechanism 158 converts the rotational motion of the power transmission mechanism 151 into a linear motion of the joint half 116, that is, a motion in which the joint half 116 is moved into and out of the bulging portion 47, and the linear motion of the joint half 116 is appropriate. The joint half 116 is rotationally moved. The cam mechanism 158 includes a base section 163 rotated by the power transmission mechanism 151 and a follower 164 provided on the joint half 116. Follower 164 is closest to the axis 162 of the coupling halves 116, circumferentially of the joint halves 116, i.e. the first cam surface 164a extending in a direction perpendicular to the rotational axis of the coupling halves 116, joint halves 116 A second cam surface 164b extending in the direction opposite to the axis 162 of the joint half 116 at an angle with respect to the rotation center line of the second half, and a third cam connected to the top of the second cam surface 164b and extending away from the first cam surface 164a And a surface 164c. The third cam surface 164 c extends substantially parallel to the center line of rotation of the joint half 116. The original node 163 is in line contact with the first cam surface 164a and the second cam surface 164b, and has a shape capable of surface contact with the third cam surface 164c.

The connector 156 places the base section 163 on the first cam surface 164a of the follower 164 of the cam mechanism 158 when the connector 156 is not connected, or brings the base section 163 most closely to the first cam surface 164a. In this state, the joint half 116 enters the bulging portion 47 of the station 2 most and is hidden. When the drive source 149 starts up, the base section 163 rotates with the gear 151 c of the power transmission mechanism 151. The rotating original node 163 moves on the first cam surface 164a of the follower 164, approaches the second cam surface 164b, and eventually rides on the second cam surface 164b. Then, the joint half 116 is pushed out of the bulging portion 47 by the force of the raw node 163 pushing the second cam surface 164 b and is connected to the joint half 115. As rotation of the joint half 116 progresses and the base section 163 comes into surface contact with the third cam surface 164 c, the entire connector 156 rotates in synchronization with the base section 163.

The joint half 116 is drawn into the bulging portion 47 by the spring force of the joint cutting spring 157. The spring force generates an appropriate frictional force between the base section 163 and the follower 164 to ensure that the base section 163 rides on the second cam surface 164 b of the follower 164.

The cam mechanism 158 looks at the joint half 115 of the cleaner body 7 from the joint half 116 of the station 2 and rotates the joint half 116 forward (clockwise) and reversely (counterclockwise) in any rotational direction. Also, it has a second cam surface 164b and a third cam surface 164c. In other words, the cam mechanism 158 has a pair of second cam surfaces 164b and third cam surfaces 164c sandwiching the first cam surface 164a.

Here, for example, the power transmission path 155 opens the discard lid 92 and the intake lid 94 by rotating the joint half 116 forward and closes the discard lid 92 and the intake lid 94 by reversing the joint half 116. explain. One second cam surface 164 b and one third cam surface 164 c connect the connector 156 with the normal rotation of the joint half 116 and open the disposal lid 92 and the intake lid 94. The other second cam surface 164 b and the other third cam surface 164 c connect the connector 156 as the joint half 116 reverses, and close the disposal lid 92 and the intake lid 94.

The connector 156 may be provided with a charging terminal 166 for supplying power from the station 2 to the secondary battery 17 to charge the secondary battery 17. The charging terminal 166 charges the secondary battery 17 in place of the charging terminal 46 provided on the pedestal 41. The charging terminals 166 are provided on both the joint half 115 of the cleaner body 7 and the joint half 116 of the station 2. The charging terminal 166 is electrically connected when the connector 156 is connected, that is, when the joint half 116 of the station 2 and the joint half 115 of the cleaner body 7 are connected.

The control circuit 172 on the station 2 side also includes a charging circuit (not shown) for the secondary battery 17 of the vacuum cleaner 3.

The switching element 177 is an element such as a bidirectional thyristor or a reverse blocking three-terminal thyristor. The switching element 177 includes a gate connected to the station control unit 51. The switching element 177 changes the input of the secondary motor blower 50 according to the change of the gate current.

The control power supply unit 178 is a power supply circuit that generates control power of the station control unit 51.

The attachment detector 45 is connected to the control circuit 172 so as to open the electric path when the detection target is in the storage state and to close the electric path when the detection target is in the use state when the detection target is not in the storage state. Is preferred.

That is, when the vacuum cleaner 3 is connected to the station 2, in other words, when the vacuum cleaner 3 is mounted to the station 2, the first attachment detector 45 a is placed on the pedestal 41. If you open the circuit. On the other hand, when the vacuum cleaner 3 is disconnected from the station 2, in other words, when the vacuum cleaner 3 is detached from the station 2, or when the vacuum cleaner 3 is detached from the pedestal 41, the first attachment detector 45a. Close the circuit. The second attachment detector 45b opens the electrical path when the pipe 8 of the vacuum cleaner 3 is attached to the station 2. Moreover, the 2nd mounting | wearing detector 45b closes an electrical path, when the pipe part 8 of the vacuum cleaner 3 separates from the station 2. FIG. The same applies to the case where the tube attachment portion 53 is provided in the cleaner body 7. In this case, the electric path which the second attachment detector 45b opens and closes is included in the control circuit 171 on the vacuum cleaner 3 side.

When at least two attachment detectors 45 of the plurality of attachment detectors 45 detect that the vacuum cleaner 3 has been attached to the station 2, the station control unit 51 detects the secondary dust container 49 from the primary dust container 13. Allow the transfer of dust to Then, the station control unit 51 determines that the vacuum cleaner 3 is attached to the station 2 after at least two of the plurality of attachment detectors 45 after the predetermined delay time has elapsed from the permission of the transfer of the dust. After a predetermined delay time has elapsed since the detection of the attachment detector 45, the secondary electric blower 50 is started to start dust transfer.

The plurality of attachment detectors 45 may include a third attachment detector 45c that detects that the main body handle 14 of the vacuum cleaner 3 is in the storage position. The plurality of attachment detectors 45 may include a third attachment detector 45c in addition to the first attachment detector 45a and the second attachment detector 45b. Further, the plurality of attachment detectors 45 may be provided with a third attachment detector 45 c instead of the second attachment detector 45 b. When the plurality of attachment detectors 45 include the first attachment detector 45a, the second attachment detector 45b, and the third attachment detector 45c, the station control unit 51 determines that all three attachment detectors 45 are connected. When it is detected that the vacuum cleaner 3 is attached to the station 2, transfer of dust from the primary dust container 13 to the secondary dust container 49 may be permitted. In addition, the station control unit 51 is a combination of two of the three attachment detectors 45, that is, the combination of the first attachment detector 45a and the second attachment detector 45b, the first attachment detector 45a and the third attachment detection. From the primary dust container 13 when it is detected that the vacuum cleaner 3 is attached to the station 2 in combination with the unit 45c or in combination with the second attachment detector 45b and the third attachment detector 45c. The transfer of dust to the secondary dust container 49 may be permitted. Furthermore, the station control unit 51 always includes the first attachment detector 45a among the three attachment detectors 45, and the two attachment detectors 45 to which the second attachment detector 45b or the third attachment detector 45c is added, When it is detected that the vacuum cleaner 3 is attached to the station 2, transfer of dust from the primary dust container 13 to the secondary dust container 49 may be permitted.

The main body handle 14 is movable between the use position and the storage position. Note that the storage position of the main body handle 14 is the position of the main body handle 14 in a state in which the main body handle 14 is stored in the handle storage recess 11 b of the main body case 11. On the other hand, the use position of the main body handle 14 is the position of the main body handle 14 in a state where the main body handle 14 is pulled out from the handle storage recess 11 b of the main body case 11.

The notification unit 179 detects that at least one of the plurality of attachment detectors 45 detects that the other attachment detector 45 has attached the vacuum cleaner 3 to the station 2 and then sends the station 2 to the station 2 within a predetermined time. When it is not detected that the vacuum cleaner 3 is attached, notification is performed. That is, at least one of the plurality of attachment detectors 45 detects that the other attachment detector 45 has attached the vacuum cleaner 3 to the station 2, and the notification unit 179 determines that the station is within a predetermined time that is predetermined. When it is not detected that the vacuum cleaner 3 is attached to 2, it is informed that the attachment state of the vacuum cleaner 3 attached to the station 2 is incomplete. The notification unit 179 is, for example, a display for displaying information such as characters, a lighted or blinking lamp, an LED (Light Emitting Diode) such as a device that appeals to the user of the electric cleaning device 1, a voice or the like synthesized electrically. A sound generator that emits a buzzer sound or the like appeals to the user's hearing of the electric cleaning device 1, a vibrator or the like that appeals to the user's touch of the electric cleaning device 1, or the like.

The cleaner body 7 is connected to the station 2 and the electric cleaning device 1 shifts to the storage mode. Then, the charge electrode 19 of the cleaner body 7 contacts the charge terminal 46 of the station 2 and is electrically connected to the charge terminal 46. The inlet of the dust transfer pipe 43 is in close contact with the outer surface of the container body 78 of the primary dust container 13 through the body case disposal port 99 of the cleaner body 7.

The station control unit 51 detects that the cleaner body 7 is connected to the station 2 based on the detection results of the plurality of attachment detectors 45. When at least two of the plurality of mounting detectors 45 detect that the cleaner body 7 is connected to the station 2, the station control unit 51 detects the drive source 149 after a predetermined delay time has elapsed. to start the. When the drive source 149 is started, the joint half 116 of the station 2 protrudes from the bulging portion 47 and is connected to the joint half 115 of the cleaner body 7. That is, the coupler 156 is coupled. The station control unit 51 continues the operation of the drive source 149. The power transmission path 155 to which the connector 156 is connected distributes and transmits the driving force of the drive source 149 to the discard lid 92, the intake lid 94, and the dust removing mechanism 95.

The disposal lid 92 and the intake lid 94 are fully opened by the driving force transmitted from the power transmission path 155. The dust removing mechanism 95 removes fine dust attached to the filters 86 and 87 by the driving force transmitted from the power transmission path 155. The station control unit 51 causes the drive source 149 to temporarily stop after continuously operating the drive source 149 for a suitable period of time during which the dust removal mechanism 95 removes fine dust attached to the filters 86 and 87, for example, for 10 seconds.

Next, the station control unit 51 starts the secondary electric blower 50. The started secondary electric blower 50 sucks air from the secondary dust container 49 and generates negative pressure. That is, the secondary electric blower 50 applies a negative pressure to the secondary dust container 49 after the drive source 149 opens the disposal lid 92. The secondary electric blower 50 applies a negative pressure to the secondary dust container 49 after the drive source 149 opens the intake lid 94. The secondary electric blower 50 applies a negative pressure to the secondary dust container 49 after the drive source 149 drives the dust removal mechanism 95.

The negative pressure acting on the secondary dust container 49 acts on the primary dust container 13 through the dust transfer pipe 43 and the waste port 91. Then, the primary dust container 13 sucks in air from the air inlet 93. At this time, air is sucked from the body connection port 18. The air sucked into the primary dust container 13 causes the coarse dust in the coarse dust collection chamber 71 to flow out from the coarse dust disposal port 101 to the dust transfer pipe 43, and the fine dust in the filter chamber 72 is the fine waste disposal port 102. Flow out to the dust transfer pipe 43. The dust (dust mixed with coarse dust and fine dust) flowing into the dust transfer pipe 43 is sucked into the secondary dust container 49 through the dust transfer pipe 43.

The first centrifugal separation unit 144 of the secondary dust container 49 separates and accumulates coarse dust from the dust flowing in from the dust transfer pipe 43. The second centrifugal separator 145 separates and accumulates fine dust passing through the first centrifugal separator 144.

The station control unit 51 operates the secondary electric blower 50 for an appropriate duration, for example, 10 seconds, and transfers substantially all the dust accumulated in the primary dust container 13 to the secondary dust container 49, The secondary electric blower 50 is stopped. Further, when the secondary electric blower 50 is stopped and the secondary dust container 49 returns to the positive pressure (that is, the atmospheric pressure), the station control unit 51 reverses the temporarily stopped driving source 149. When the drive source 149 starts to reverse, the joint half 116 of the station 2 separates from the joint half 115 of the cleaner body 7 and is pulled into the bulging portion 47 once. That is, the connection of the connector 156 is temporarily released. The station control unit 51 continues the reverse rotation of the drive source 149. When the reverse rotation of the drive source 149 continues, the joint half 116 of the station 2 again protrudes from the bulging portion 47 and is connected to the joint half 115 of the cleaner body 7. That is, the coupler 156 is coupled. The station control unit 51 continues the operation of the drive source 149. The power transmission path 155 to which the connector 156 is connected distributes and transmits the driving force of the drive source 149 to the discard lid 92, the intake lid 94, and the dust removing mechanism 95.

The disposal cover 92 and the intake cover 94 are fully closed by the driving force transmitted from the power transmission path 155. At this time, the dust removing mechanism 95 is also operated by the driving force transmitted from the power transmission path 155, but since fine dust attached to the filters 86 and 87 is removed, it does not substantially function. The station control unit 51 continuously reverses the drive source 149 for a suitable period of time during which the disposal lid 92 and the intake lid 94 are fully closed, for example, for 3 seconds.

Then, after the disposal lid 92 and the intake lid 94 are completely closed, the station control unit 51 temporarily stops the drive source 149. Then, the station control unit 51 causes the drive source 149 to rotate forward again. When the drive source 149 starts to rotate forward, the joint half 116 of the station 2 separates from the joint half 115 of the cleaner body 7 and is pulled into the bulging portion 47 once. That is, the connection of the connector 156 is released again. The station control unit 51 stops the drive source 149 after the joint half 116 of the station 2 is drawn into the bulging portion 47. In other words, the connector 156 moves to the retracted position after finishing the operation of the dust removal mechanism 95, the discard lid 92, and the intake lid 94, that is, the follow mechanism 114.

Next, the handle 56 of the vacuum cleaner 3 according to the present embodiment, the pedestal 41 of the station 2, and the speed reduction mechanism 44 will be described.

FIG. 25 is a side view of the electric cleaning device according to the embodiment of the present invention.

FIG. 26 is a perspective view of the speed reduction mechanism of the electric cleaning device according to the embodiment of the present invention.

27 and 28 are cross-sectional views of the speed reduction mechanism of the electric cleaning apparatus according to the embodiment of the present invention.

Note that FIG. 27 shows the decelerating mechanism 44 which is jumping up and approaching the cleaner body 7 and standing by. FIG. 28 shows the decelerating mechanism 44 moved so that the cleaner body 7 can move forward when the cleaner body 7 is separated from the station 2.

As shown in FIGS. 25 to 28 in addition to FIGS. 1 and 2, the handle 56 of the electric cleaning device 1 according to the present embodiment is vertically disposed in the storage posture in which the electric vacuum cleaner 3 is placed at the station 2. It extends. The handle 56 is provided on the opposite side of the dust collection unit 42 in the storage state in which the vacuum cleaner 3 is placed at the station 2. In other words, the handle 56 is disposed on the front side of the station 2 in a stored state in which the vacuum cleaner 3 is placed at the station 2.

The electric cleaning device 1 raises the cleaner body 7 in the use posture to change the posture of the cleaner body 7 to the storage posture, and lowers the cleaner body 7 in the storage posture onto the pedestal 41 from above the station 2. become storage form. At this time, when the vacuum cleaner body 7 is pulled up by holding the handle 56, the posture of the vacuum cleaner 3 is such that the front of the vacuum cleaner body 7 is upward according to the positional relationship of the handle 56, the cleaner body 7 and the wheels 12. It changes to the storage posture which turns to the back, and turns the back downward (it stands up). That is, when the handle 56 is pulled up, the vacuum cleaner body 7 gets up around the rotation center line of the wheel 12 with the wheel 12 grounded. The user can hold the finger 56 on the handle 56 and pull up the cleaner body 7 with a simple operation by raising the cleaner body 7 with a simple operation. Therefore, when placing the cleaner body 7 on the pedestal 41 of the station 2, the burden on the user is reduced, and the convenience is excellent.

The pedestal 41 is provided with a pedestal surface 41 a and a ground guide surface 181 which contacts the wheel 12 in the process of the cleaner body 7 in the stored posture being fallen. Further, the pedestal 41 is provided with an overturning fulcrum portion 182 which supports the cleaner body 7 when the cleaner body 7 in the stored posture falls down.

The electric cleaning device 1 is provided on the fall fulcrum portion 182 or the cleaner body 7 so that the non-slip portion 183 prevents the slip between the cleaner body 7 and the fall fulcrum portion 182 when the cleaner body 7 in the storage posture falls down. It is provided.

The mounting table surface 41 a has an arc shape that follows the shape of the rear surface of the cleaner body 7, that is, the arc shape. The mounting table surface 41a is recessed in an arc shape with respect to the horizontal plane.

The ground contact guide surface 181 is an inclined surface which is lowered toward the front of the station 2 so that the cleaner body 7 which falls from the storage position to the use position can easily advance to the front of the station 2. The ground guide surface 181 is connected to an arc-shaped wheel arrangement recess 185 for receiving the wheel 12 of the cleaner body 7 stored in the station 2. Therefore, the wheel 12 smoothly contacts the ground guide surface 181 in the process of the cleaner body 7 falling from the storage posture to the use posture, and supports the cleaner body 7.

The overturning fulcrum portion 182 is provided above the lowermost portion of the table surface 41a. Therefore, when the cleaner body 7 in the storage posture is turned over, the cleaner body 7 falls down like a ladder around the fall fulcrum portion 182 and smoothly transitions to the use posture.

By the way, when the cleaner body 7 falls to the use posture, it is preferable that the contact portion between the fall fulcrum portion 182 and the cleaner body 7 does not slip. When the point of contact between the fall fulcrum portion 182 and the cleaner body 7 slips, it becomes difficult to determine the behavior when the cleaner body 7 falls down, or the path or trajectory to fall down. Therefore, it is preferable that the contact point between the overturning fulcrum portion 182 and the cleaner body 7 does not slip significantly while allowing a slight slip. Therefore, the seal member 153 provided at the inlet of the dust transfer pipe 43 doubles as the overturning fulcrum portion 182. The seal member 153 functions as a fall fulcrum portion 182 at a position where the side portion 43 b on the front side of the dust transfer pipe 43 is sealed. The seal member 153 is preferably a synthetic rubber such as natural rubber or silicone rubber in order to seal the connecting portion between the dust transfer pipe 43 and the primary dust container 13. The seal member 153 is not slippery with respect to the cleaner body 7 and is in contact with the cleaner body 7 in the stored state, so it is suitable as a fall fulcrum portion 182 and also functions as a non-slip portion 183.

The overturning fulcrum portion 182 may be a member other than the seal member 153. That is, the overturning fulcrum portion 182 may be a rib-like protrusion provided on the pedestal 41. The non-slip portion 183 may also be a member other than the seal member 153. The non-slip portion may be provided on the side of the cleaner body 7 as long as it is sandwiched between the cleaner body 7 and the overturning fulcrum portion 182, or may be provided on the station 2 side.

The speed reduction mechanism 44 is provided at the tip of the pedestal 41 of the station 2. The speed reduction mechanism 44 reduces the moving speed of the cleaner body 7 in the process of moving the cleaner body 7 in the storage posture to the use posture, that is, in the process of falling down. The reduction gear mechanism 44 stores the energy and consumes the stored energy when the cleaner body 7 moves so as to be able to move forward, the reduction gear mechanism when the cleaner body 7 moves so as to be able to move. And an elastic member 193 for returning 44 to the standby position.

The hinge 191 includes a shaft 195 supported by the pedestal 41 of the station 2 and a plate portion 196 to which the support plate portion 192 is fixed. The plate portion 196 has a hole 197 in which the shaft 195 is disposed. The plate portion 196 swings around the shaft 195. That is, the decelerating mechanism 44 moves so as to fall between the standby position approaching the cleaner body 7 by the hinge 191 and the deployed position where the cleaner body 7 can be advanced. The shaft 195 extends in the width direction of the stored cleaner body 7. In other words, the axis 195 and the rotation center line of the wheel 12 of the cleaner body 7 mounted on the pedestal 41 are disposed substantially in parallel. Therefore, when the reduction mechanism 44 falls, the cleaner body 7 is in the use position.

The support plate portion 192 moves from the stored state to the use state, that is, contacts the falling main case 11 to support the cleaner body 7. The support plate portion 192 extends in the width direction of the main body case 11 so as to stably support the moving cleaner main body 7. It is preferable that the support plate portion 192 has a protective material, for example, a raised surface on the surface in contact with the cleaner body 7.

Further, when the support plate portion 192 moves so as to allow the cleaner body 7 to move forward, in other words, when the cleaner body 7 falls from the storage posture to the use posture, the cleaner body 7 is easily detached from the pedestal 41 It becomes a downward slope from the connection guide portion 148 toward the surface to be cleaned.

The speed reduction mechanism 44 may limit the moving speed by a so-called brake mechanism 198. The speed reduction mechanism 44 may be provided with an oil damper (not shown) for containing hydraulic oil.

The elastic member 193 pulls the user's operation force and the overturning moment of the cleaner main body 7 when the user pulls any part of the pipe part 8 of the vacuum cleaner 3, preferably the hand operation pipe 23 or the grip part 25. It lost the moves the reduction gear mechanism 44 (defeat). By this movement, the elastic member 193 stores energy for causing the speed reduction mechanism 44.

The elastic member 193 is, for example torsion spring. The elastic member 193 does not prevent the vacuum cleaner main body 7 placed on the pedestal 41 in the storage posture from falling down due to the application of an external force, and causes the speed reduction mechanism 44 to the standby position after the vacuum cleaner main body 7 is separated from the station 2.

The charging terminal 46 of the station 2 can be connected to the cleaner body 7 in the stored state, and the connection with the cleaner body 7 is released when the cleaner body 7 is turned to the use posture. For this reason, the terminal cover 199 of the charging terminal 46 has a slit 199a directed upward of the station 2 and a slit 199b directed in the direction of separating the vacuum cleaner 3 from the station 2, ie, the front direction of the station 2. (Figure 22). The charge terminal 46 is connected to the charge electrode 19 of the cleaner body 7 inserted into the slits 199a and 199b.

By the way, the vacuum cleaner 3 can be used by raising the vacuum cleaner main body 7 from the pedestal 41 to the upper side of the station 2 and lowering it to the use posture on the surface to be cleaned (floor surface). However, when using the vacuum cleaner 3, raising and moving the cleaner body 7 is less convenient.

Therefore, the electric cleaning device 1 according to the present embodiment can tilt and tilt the cleaner body 7 in the storage posture and start using the electric cleaner 3. For example, when the user pulls the dust collecting hose 22 in the front direction of the station 2 by holding the pipe 8 of the vacuum cleaner 3 at any part of the pipe 8 of the vacuum cleaner 3, preferably the hand operation pipe 23 or the grip 25 7 falls into a use posture (FIG. 25).
