As shown in FIG. 3 shows a state in which the connection pipe 21 of the pipe part 8 is separated from the cleaner body 7 . 4 shows a state in which the connection pipe 21 is attached to the cleaner body 7 .

As shown in FIG.3 and FIG.4, the vacuum cleaner main body 7 of the electric cleaning apparatus 1 which concerns on embodiment of this invention is a tubular second half part laid horizontally in the width direction of the main body case 11, and a vacuum cleaner The main body 7 is provided with the main body case 11 provided with the front part which expands in the arc shape toward the front from the second half part of the cylinder in planar view. The rear surface of the main body case 11 has an arc shape when viewed from the side surface of the vacuum cleaner main body 7 .

The main body connector 18 extends along a line (hereinafter referred to as center line C) passing through the substantially center in the width direction of the main body case 11 and the substantially center in the height direction, and reaches the primary dust container 13 and have. 3 and 4 are cross-sectional views passing through the center line C.

The secondary filter outlet 89 discharges the air that has passed through the filters 86 and 87 to the communication air passage 66 .

The filter chamber 72 is adjacent to the coarse dust collection chamber 71 . The filter chamber 72 functions as a fine dust collecting chamber for accumulating fine dust captured by the filter unit 69 by filtration separation. Fine dust passing through the first mesh filter 77 and the second mesh filter 84 is captured by the pair of thinner filters 86 and 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 arrange|positioned rather than the filters 86 and 87 on the upstream side.

That is, the communication air path 66 branches into a plurality and reaches the primary electric blower 15 . The communication air passage 66 is divided into two air passages 66a and 66b, for example. A plurality of, for example, two air passages 66a and 66b are interposed between the intake ports 78a for guiding air to the separation portion 64 . The air passage cross-sectional areas S of the two air passages 66a and 66b are substantially equal. The two air passages 66a and 66b have a shape symmetrical with respect to a surface including the rotational center line of the fan of the primary electric blower 15 . In other words, the plurality of air passages 66a and 66b are formed from the first mesh filter 77, the second mesh filter 84, and the first mesh filter 77, the second mesh filter ( 84), and the filter part 69, which is knitted and arranged on the edge side, and is spaced apart from each other. The two air passages 66a and 66b gather and join at the end of the communication air passage 66 connected to the primary electric blower 15 .

That is, the second gear 132 and the gear 113 of the vibration damping mechanism 95 are integrally rotated. Since the second gear 132 is larger than the first gear 131, the vibration damping mechanism 95 that operates while bouncing or deforming the filters 86 and 87 is replaced with a smaller output motor (station 2 to be described later). ) can be driven by a driving source 169).

The second transmission mechanism 127 opens and closes the waste cover 92 by a driving force input to the joint half body 121 . The third transmission mechanism 128 opens and closes the intake cover 94 by a driving force input to the joint half body 121 . The intake cover 94 and the waste cover 92 are opened and closed collectively. In other words, when the second delivery mechanism 127 opens the waste cover 92 , the third delivery mechanism 128 also opens the intake cover 94 . Further, when the second delivery mechanism 127 closes the waste cover 92 , the third delivery mechanism 128 also closes the intake cover 94 .

The third transmission mechanism 128 includes a first gear 131 shared with the first transmission mechanism 126 , a lever portion 134 disposed in an arc shape and having teeth 134a engaged with the first gear 131 . , a guide part 135 for guiding the swinging of the lever part 134 , and a pair of stoppers 136 for defining the swinging range of the lever part 134 .

The lever part 134 has a pivoting center coincident with the rotational center of the second gear 132 . That is, the lever part 134 is supported together with the second gear 132 by a shaft that rotatably supports the second gear 132 . The lever part 134 is directly connected to the intake cover 94 .

The guide part 135 is provided with the groove 137 provided in the container body 78, and the guide plate 138 arrange|positioned in the groove 137. As shown in FIG. The groove 137 extends in an arc shape along the trajectory of the swing of the lever part 134 . The guide plate 138 is integrated with the lever part 134 .

The stopper 136 defines (regulates) the swing range of the lever part 134 according to the fully closed and fully open positions of the waste cover 92 and the intake cover 94 .

The second transmission mechanism 127 includes a first gear 131 shared with the first transmission mechanism 126 and the third transmission mechanism 128 ; a lever portion 134 , a guide portion 135 , and a stopper 136 shared with the third transmission mechanism 128 ; a slider 139 that converts the oscillation of the lever part 134 into a reciprocating motion and transmits it to the waste cover 92; and a waste cover closing spring 140 that generates an elastic force to completely close the waste cover 92 . The slider 139 pushes and overcomes the elastic force of the waste cover closing spring 140 to open the waste cover 92 . In addition, the slider 139 closes the waste cover 92 using the elastic force of the waste cover closing spring 140 .

Here, the power transmission mechanism 96 transmits the driving force from the station 2 to the vibration damping mechanism 95 over an appropriate period, while the waste cover 92 and the intake cover 94 are fully open or fully closed. After that, the transmission of power from the station 2 to the waste cover 92 and the intake cover 94 is interrupted (insulated) even within an appropriate period during which the vibration damping mechanism 95 is in operation.

That is, the second transmission mechanism 127 blocks the transmission of the driving force from the joint half body 121 to the waste cover 92 when the waste cover 92 is fully opened or completely closed. In addition, the third transmission mechanism 128 blocks transmission of the driving force from the joint half body 121 to the intake cover 94 when the intake cover 94 is fully opened or completely closed.

Specifically, when the waste cover 92 and the intake cover 94 are fully opened or completely closed, the second transmission mechanism 127 and the third transmission mechanism 128 are connected with the teeth 134a of the lever part 134 and The engagement of the first gear 131 is released. That is, the teeth 134a arranged in an arc shape are provided (limited) in a range where they come out of the first gear 131 when the waste cover 92 and the intake cover 94 are fully opened or completely closed. .

The teeth 134a of the lever part 134 do not completely resist the waste cover 92 which is prevented from moving when the waste cover 92 is completely closed or fully opened, and comes out from the first gear 131 and the driving force ( torque) is blocked. When the intake cover 94 is completely closed or fully opened, the teeth 134a of the lever part 134 come out of the first gear 131 and block the transmission of the driving force (torque).

In addition, when the power transmission mechanism 96 returns the meshing between the teeth 134a of the lever part 134 and the first gear 131, a driving source that promotes smooth meshing of both, for example, a return spring 154. is provided. The return spring 154 is collapsed when the waste cover 92 and the intake cover 94 are fully opened or fully closed to store energy. In addition, the return spring 154 expends energy to push the lever portion 134 back when the waste cover 92 and the intake cover 94 start to open, or when they start closing, the lever portion 134 . Helps to return the mesh of the teeth (134a) and the first gear (131).

In addition, it is preferable that the waste cover 92 and the intake cover 94 remain fully open while the vibration suppression mechanism 95 operates over an appropriate period and filters the filters 86 and 87 are removed. . For example, if the vibration damping mechanism 95 is reciprocated by switching the forward and reverse rotation of the motor (the drive source 169 of the station 2 to be described later), the waste cover 92 and the intake cover 94 will cause the motor to reciprocate. Each time it switches, it opens or closes, which is undesirable. Therefore, the vibration damping mechanism 95 according to the present embodiment has a configuration in which the driven part 106 can reciprocate by the teeth 113 rotating in one direction as shown in FIG. 9 .

A power transmission path 175 for transmitting a driving force to the motor, and a connector 176 for connecting and disconnecting the power transmission path 175 between the station 2 and the vacuum cleaner 3 are provided.

The power transmission path 175 includes a power transmission mechanism 96 on the side of the vacuum cleaner 3 and a power transmission mechanism 171 on the side of the station 2 . The connector 176 connects the power transmission mechanism 96 on the side of the vacuum cleaner 3 and the power transmission mechanism 171 on the side of the station 2 to function the power transmission path 175 . The power transmission path 175 is from the drive source 169 on the side of the station 2 to the driven mechanism 120 on the side of the vacuum cleaner 3, that is, the vibration damping mechanism 95, the waste cover 92, and the intake cover 94. to transmit the driving force.

The power transmission mechanism 171 and the coupler 176 excluding the joint half body 121 of the vacuum cleaner main body 7 are covered with the bulging part 47 of the pedestal 41 . The connector 176 is in a retracted position where contact with the vacuum cleaner 3 can be avoided when the vacuum cleaner 3 is mounted on the station 2, while in a state where the vacuum cleaner 3 is mounted on the station 2 The driving force of the driving source 169 is moved to a connection position capable of being transmitted to the vacuum cleaner 3 . The bulging part 47 accommodates the joint half body 122 so that it can retract and retract.

The connector 176 is a shaft joint 129 and a driving source that generates a force to cut the shaft joint 129, for example, a joint cutting spring 177 and a shaft joint 129 with a driving force generated by the driving source 169. ) is provided with a cam mechanism 178 for connecting them. The connector 176 connects the shaft joint 129 with the driving force of the driving source 169 and cuts off (insulates) the shaft joint 129 with the elastic force of the joint cutting spring 177 .

Shaft joint 129 is a so-called dog clutch or coupling. The shaft joint 129 includes a joint half body 121 installed in the power transmission mechanism 96 of the vacuum cleaner 3 and a half joint body 122 installed in the power transmission mechanism 171 of the station 2 , have.

The joint half body 121 is provided with a plurality of arc-shaped grooves 181 arranged in a circle. The joint half body 122 is provided with a plurality of shafts 182 arranged in a circle. Each shaft 182 has a diameter dimension that can enter and exit the arc-shaped groove 181 . The shaft 182 is preferably of a tapered shape to facilitate insertion into the arc-shaped groove 181 .

The joint half body 122 is always rotated by the driving force transmitted by the power transmission mechanism 171 . The joint half body 121 rotates together with the joint half body 122 as the shaft joint 129 is connected. The joint half body 122 protrudes from the bulge 47 of the station 2 and is connected to the joint half body 121 . The half-joint body 122 protrudes in the width direction of the cleaner body 7 from the bulge 47 disposed on the side of the cleaner body 7 and is connected to the half-joint body 121 . In other words, the connector 176 moves in the direction in which the cleaner body 7 moves, that is, when the cleaner body 7 is separated from the station 2 and the cleaner body 7 is returned to the station 2 . The joint half body 122 protrudes and protrudes from the bulge 47 in a direction intersecting the vertical direction to connect the shaft joint 129 . That is, the moving direction of the electric vacuum cleaner 3 when the electric vacuum cleaner 3 is attached to the station 2 intersects in the direction in which the coupler 176 moves between the retracted position and the connected position. For that reason, the coupler 176 prevents, for example, dust from entering the station 2 from the gap between the bulging portion 47 and the joint half body 122, to ensure good operation of the power transmission mechanism 171. can

In addition, the half-joint 122 protrudes from the bulge 47 in the width direction of the cleaner body 7 and is connected to the half-joint 121, and is installed by protruding from the connection guide 168, and the station ( When the vacuum cleaner main body 7 is connected to 2), it may be connected to the joint half body 121 at the same time (joint half body 122 of the dashed-dotted line in FIG. 23). In addition, the joint half body 122 may be disposed in the dust recovery unit 42, protrude forward of the station 2 and be connected to the joint half body 121 (in FIG. 122)).

The joint cutting spring 177 tensions the joint half body 122 in a direction to cut the shaft joint 129 , that is, in a direction to separate it from the joint half body 121 . In other words, the joint cutting spring 177 is drawing in the joint half body 122 in the direction to be buried in the bulging part 47 .

The cam mechanism 178 is provided on the station 2 side. The cam mechanism 178 is a so-called single-sided cam. The cam mechanism 178 converts the rotational motion of the power transmission mechanism 171 into a linear motion of the half-joint 122, that is, a motion in which the half-joint 122 protrudes and retracts from the bulge 47, and also the half-joint 122 ), when the linear motion is properly progressed, the joint half body 122 is rotated. The cam mechanism 178 is provided with the circular node 183 rotated by the power transmission mechanism 171, and the follower blade 184 provided in the joint half body 122. As shown in FIG. The follower 184 is closest to the axis 182 of the joint half body 122, and the first cam surface 184a extending in the circumferential direction of the joint half body 122, that is, in a direction orthogonal to the rotation center line of the joint half body 122. ) and the second cam surface 184b extending in the opposite direction to the axis 182 of the joint half body 122 at an angle with respect to the rotation center line of the half joint 122, and connected to the top of the second cam surface 184b A third cam surface 184c extending in a direction away from the first cam surface 184a is provided. The third cam surface 184c extends substantially parallel to the rotation center line of the joint half body 122 . The ring 183 has a shape capable of line contact with the first cam surface 184a and the second cam surface 184b, and surface contact with the third cam surface 184c.

When the driving source 169 is started, the disc 183 rotates together with the gear 171c of the power transmission mechanism 171 . The rotating circular segment 183 moves the first cam surface 184a of the driven segment 184, approaches the second cam surface 184b, and both rides up on the second cam surface 184b. Then, the joint half body 122 is pushed upward from the bulging part 47 by the force of the circular segment 183 suppressing the second cam surface 184b, and is connected to the joint half body 121 . When the rotation of the joint half body 122 proceeds and the ring 183 comes into surface contact with the third cam surface 184c, the entire coupler 176 rotates in synchronization with the ring 183 .

In addition, the joint half body 122 is drawn into the bulge 47 by the elastic force of the joint cut spring 177 . This elastic force generates an appropriate frictional force between the proximal segment 183 and the follower segment 184 , and ensures that the segment 183 rides up on the second cam surface 184b of the follower segment 184 .

The cam mechanism 178 sees the joint half body 121 of the vacuum cleaner main body 7 from the joint half body 122 of the station 2, and rotates the joint half body 122 forward (clockwise) and reversely (counterclockwise). In any rotational direction, it has a second cam surface 184b and a third cam surface 184c. In other words, the cam mechanism 178 has a pair of a second cam surface 184b and a third cam surface 184c sandwiching the first cam surface 184a therebetween.

Here, for example, the power transmission path 175 opens the waste cover 92 and the intake cover 94 by turning the fitting half 122 electrostatically, and by reversing the fitting half 122, the waste cover 92 and It will be described as closing the intake cover 94 . The one 2nd cam surface 184b and the one 3rd cam surface 184c connect the coupler 176 with the blackout of the joint half body 122, and open the waste cover 92 and the intake cover 94. do. The other 2nd cam surface 184b and the other 3rd cam surface 184c connect the coupler 176 with the inversion of the joint half body 122, and close the waste cover 92 and the intake cover 94. do.

In addition, the connector 176 may be provided with a charging terminal 186 for supplying electric power to the secondary battery 17 from the station 2 and charging the secondary battery 17 . The charging terminal 186 charges the secondary battery 17 in place of the charging terminal 46 provided on the pedestal 41 . The charging terminal 186 is provided on both the half-joint body 121 of the vacuum cleaner main body 7 and the half-joint body 122 of the station 2 . The charging terminal 186 is electrically connected when the connector 176 is connected, that is, when the joint half body 122 of the station 2 and the joint half body 121 of the cleaner body 7 are connected.

The vacuum cleaner body 7 is connected to the station 2 , so that the electric cleaning device 1 shifts to the storage mode. Then, the charging electrode 19 of the cleaner body 7 contacts the charging terminal 46 of the station 2 , and is electrically connected to the charging 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 main body case disposal port 100 of the cleaner body 7 .

Fig. 27 is a sequence diagram relating to the movement of dust from the electric vacuum cleaner to the station by the electric cleaning apparatus according to the embodiment of the present invention.

As shown in FIG. 27 , the drive source 169 of the electric cleaning apparatus 1 according to the present embodiment is secondary from the primary dust container 13 after the electric cleaner 3 is accommodated in the station 2 . The waste cover 92 and the intake cover 94 are closed by maintaining the stop until the transfer of the dust to the dust container 49 is started.

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 mounted detectors 45 . The station control unit 51 detects that the cleaner main body 7 is connected to the station 2 by at least two of the plurality of mounting detectors 45. After a predetermined delay time has elapsed, the drive source ( 169) is started. When the driving source 169 is started, the joint half body 122 of the station 2 protrudes from the bulge 47 and is connected to the joint half body 121 of the cleaner body 7 . That is, the connector 176 is connected (time lag α in Fig. 27). The station control unit 51 continues to operate the driving source 169 even after the connector 176 is connected. The power transmission path 175 to which the connector 176 is connected distributes and transmits the driving force of the driving source 169 to the waste cover 92 , the suction cover 94 , and the vibration damping mechanism 95 .

By the driving force transmitted from the power transmission path 175 , the waste cover 92 and the intake cover 94 are fully opened. That is, the secondary dust container 49 is fluidly connected to the primary dust container 13 through the waste port 91 and the dust transfer pipe 43 when the vacuum cleaner 3 is accommodated in the station 2 . do.

In addition, by the driving force transmitted from the power transmission path 175 , the vibration damping mechanism 95 removes fine dust adhering to the filters 86 and 87 . The station control unit 51 continuously operates the driving source 169 for an appropriate period during which the vibration damping mechanism 95 removes fine dust adhering to the filters 86 and 87, for example, 10 seconds, and then stop once.

Then, the secondary electric blower 50 generates a negative pressure after the driving source 169 completely opens the waste cover 92 and the intake cover 94 . The station control unit 51 starts the secondary electric blower 50 . The started secondary electric blower 50 draws air from the secondary dust container 49 to generate negative pressure. That is, the secondary electric blower 50 applies a negative pressure to the secondary dust container 49 after the driving source 169 opens the waste cover 92 . The secondary electric blower 50 applies a negative pressure to the secondary dust container 49 after the driving source 169 opens the intake cover 94 . The secondary electric blower 50 applies a negative pressure to the secondary dust container 49 after the driving source 169 drives the vibration damping mechanism 95 .

In the example shown in Fig. 27, the drive source 169 stops the vibration damping mechanism 95 and then starts the secondary electric blower 50, but the drive source 169 opens the waste cover 92 and After the intake cover 94 is opened, the secondary electric blower 50 may be started while the vibration damping mechanism 95 is being driven.

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 air from the intake port 93 . At this time, air is also sucked in from the main body connecting 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 also fine dust in the filter chamber 72 . flows out from the fine dust disposal port 102 to the dust transfer pipe 43 . The dust (dust mixed with coarse dust and fine dust) introduced into the dust transfer tube 43 is sucked into the secondary dust container 49 through the dust transfer tube 43 .

The first centrifugal separator 164 of the secondary dust container 49 separates and accumulates coarse dust from the dust introduced from the dust transfer pipe 43 . The second centrifugal separator 165 separates and accumulates fine dust passing through the first centrifugal separator 164 .

The station control unit 51 operates the secondary electric blower 50 for an appropriate duration, for example, 10 seconds to convert substantially all of the dust accumulated in the primary dust container 13 into the secondary dust container 49 . After moving, the secondary electric blower 50 is stopped. In addition, the station control unit 51 controls the drive source 169 to temporarily stop when the secondary electric blower 50 stops and the secondary dust container 49 returns to a static pressure (ie, atmospheric pressure, time lag β in FIG. 27 ). reverse the When the driving source 169 starts to reverse, the joint half body 122 of the station 2 is separated from the joint half body 121 of the cleaner body 7 and is once drawn into the bulge 47 . That is, the connection of the connector 176 is once released. The station control unit 51 continues to reverse the drive source 169 . When the reversal of the driving source 169 continues, the joint half body 122 of the station 2 protrudes again from the bulge 47 and is connected to the joint half body 121 of the cleaner body 7 (time in FIG. 27 ). lag γ). That is, the connector 176 is connected. The station control unit 51 continues the operation of the driving source 169 . The power transmission path 175 to which the connector 176 is connected distributes and transmits the driving force of the driving source 169 to the waste cover 92 , the intake cover 94 , and the vibration damping mechanism 95 .

The driving source 169 closes the waste port 91 by generating a closing driving force of the waste cover 92 after stopping the operation of the secondary electric blower 50 generating negative pressure to transport the dust. In addition, the driving source 169 closes the intake port 93 by generating a closing driving force of the intake cover 94 after stopping the operation of the secondary electric blower 50 generating negative pressure to transport the dust. By the driving force transmitted from the power transmission path 175 , the waste cover 92 and the intake cover 94 are completely closed. The station control unit 51 continues to reverse the drive source 169 for an appropriate period during which the waste cover 92 and the intake cover 94 are fully closed, for example, 3 seconds.

Then, the station control unit 51 temporarily stops the driving source 169 after the waste cover 92 and the intake cover 94 are completely closed. Then, the station control unit 51 turns off the driving source 169 again. When the driving source 169 starts to blackout, the joint half body 122 of the station 2 is separated from the joint half body 121 of the cleaner body 7 and is once drawn into the bulge 47 . That is, the connection of the connector 176 is released again. The station control unit 51 stops the driving source 169 after the joint half body 122 of the station 2 is drawn into the bulge 47 . In other words, the coupler 176 moves to the retracted position when the vibration damping mechanism 95, the waste cover 92, and the intake cover 94, that is, the driven mechanism 120, are operated.

Next, the handle 55 of the vacuum cleaner 3 which concerns on this embodiment, the pedestal 41 of the station 2, and the reduction mechanism 44 are demonstrated.

It is a side view of the electric cleaning apparatus which concerns on embodiment of this invention.

It is a perspective view of the speed reduction mechanism of the electric cleaning apparatus which concerns on embodiment of this invention.

30 and 31 are cross-sectional views of the speed reduction mechanism of the electric cleaning apparatus according to the embodiment of the present invention.

In addition, FIG. 30 shows the speed reduction mechanism 44 which jumps up and approaches the cleaner main body 7 and stands by. 31 shows the speed reduction mechanism 44 moved so that the cleaner body 7 can proceed when the cleaner body 7 is separated from the station 2 .

In addition to Figs. 1 and 2, as shown in Figs. 28 to 31 , the handle 55 of the electric cleaning apparatus 1 according to the present embodiment is such that the electric vacuum cleaner 3 is mounted on the station 2 . is extended in the vertical direction in the stowed position. The handle 55 is provided on the opposite side of the dust recovery unit 42 in a stored state in which the vacuum cleaner 3 is mounted on the station 2 . In other words, the handle 55 is disposed on the front side of the station 2 in a stowed state in which the vacuum cleaner 3 is mounted on the station 2 .

The electric cleaning apparatus 1 raises the vacuum cleaner main body 7 in a use posture, changes the posture of the vacuum cleaner main body 7 to a stowed posture, and supports the vacuum cleaner main body 7 in this stowed posture from above the station 2 . By lowering to (41), it becomes a storage form. At this time, if the cleaner body 7 is pulled up by holding the handle 55, the posture of the vacuum cleaner 3 is determined by the positional relationship of the handle 55, the center of the cleaner body 7, and the wheels 12, The front side of the vacuum cleaner main body 7 is made to face upward, and it is easily changed to the storage posture which makes the back surface downward (stands up). That is, when the handle 55 is pulled up, the cleaner body 7 occurs around the rotation center line of the wheel 12 while the wheel 12 is grounded. The user can raise the vacuum cleaner body 7 by placing a finger on the handle 55 and lifting the cleaner body 7 upright, holding the handle 55 as it is. Therefore, when the vacuum cleaner main body 7 is mounted on the pedestal 41 of the station 2, the user's burden is reduced, and it is excellent in convenience.

The pedestal 41 has a stand surface 41a and a grounding guide surface 201 that is in contact with the wheels 12 while the vacuum cleaner main body 7 is collapsed from the stowed position to the use position. In addition, the pedestal 41 is provided with an inverting fulcrum portion 202 for supporting the vacuum cleaner body 7 when the vacuum cleaner body 7 is collapsed from the stowed position to the use position.

The electric cleaning device 1 is installed on the falling-off point portion 202 or the vacuum cleaner body 7, and when the vacuum cleaner body 7 falls from the stowed position to the use position, the It is provided with the anti-slip part 203 which inhibits slipping.

The stand surface 41a has an arc shape imitating the shape of the rear surface of the vacuum cleaner main body 7 , that is, an arc shape. The stand surface 41a is recessed in an arc shape with respect to the horizontal plane.

The grounding guide surface 201 is an inclined surface that descends toward the front of the station 2 so that the vacuum cleaner main body 7, which is collapsed from the stowed position to the use position, easily advances toward the front of the station 2 . The grounding guide surface 201 is in contact with the circular arc-shaped wheel arrangement recessed portion 205 for accommodating the wheels 12 of the cleaner body 7 housed in the station 2 in succession. Therefore, the wheel 12 smoothly contacts the grounding guide surface 201 and supports the cleaner main body 7 in the process of the vacuum cleaner main body 7 falling down from the stowed posture to the use posture.

The conduction fulcrum portion 202 is provided above the lowermost portion of the stand surface 41a. Therefore, when the vacuum cleaner main body 7 in the stowed position is knocked down, the vacuum cleaner main body 7 collapses like a lever centering on the falling fulcrum part 202, and smoothly shifts to the use position.

By the way, when the vacuum cleaner body 7 is collapsed from the stowed position to the use position, it is preferable that the contact portion between the fall-over fulcrum portion 202 and the cleaner body 7 does not slide. If the contact portion between the fall-down fulcrum portion 202 and the vacuum cleaner main body 7 slides, it becomes difficult to determine the behavior when the cleaner main body 7 falls down, or the trajectory or trajectory of the fall. For this reason, it is preferable that the contact portion of the falling-off point portion 202 and the cleaner body 7 permits slight slippage but does not significantly slip. Therefore, the sealing member 173 provided at the inlet of the dust transfer pipe 43 also serves as the conduction point portion 202 . The sealing member 173 functions as the conduction fulcrum portion 202 for sealing the side portion 43b on the front side of the dust transfer pipe 43 . Since the sealing member 173 seals the connection portion between the dust transfer pipe 43 and the primary dust container 13 , it is preferably made of synthetic rubber such as natural rubber or silicone rubber. Since this sealing member 173 is not slippery with respect to the vacuum cleaner main body 7 and is in contact with the vacuum cleaner main body 7 in a stored state, it is preferable as the fall-over fulcrum part 202, and also functions as the non-slip part 203. .

In addition, the conduction point part 202 may be a member other than the sealing member 173. That is, the conduction point portion 202 may be a rib-shaped projection provided on the pedestal 41 . In addition, the non-slip part 203 may also be members other than the sealing member 173. The anti-slip part may be fitted between the vacuum cleaner main body 7 and the fall-off fulcrum part 202, and may be provided in the cleaner main body 7 side, and may be provided in the station 2 side.

The speed reduction mechanism 44 is provided at the distal end of the pedestal 41 of the station 2 . The speed reduction mechanism 44 reduces the moving speed of the cleaner body 7 in a process in which the cleaner main body 7 moves (changes the posture) from the stowed posture to the use posture, ie, falls down. The speed reduction mechanism 44 stores energy when the hinge 211, the support plate portion 212 oscillatingly supported by the hinge 211, and the cleaner body 7 move so as to be able to proceed, and releases the accumulated energy. The elastic member 213 which consumes and returns the speed reduction mechanism 44 to a standby position is provided.

The hinge 211 has a shaft 215 supported by the pedestal 41 of the station 2 and a plate 216 to which the support plate 212 is fixed. The plate portion 216 has a hole 217 for arranging the shaft 215 . The plate portion 216 oscillates about the axis 215 . That is, the deceleration mechanism 44 moves so as to fall down between a standby position approaching the cleaner body 7 by the hinge 211 and a deployed position where the cleaner body 7 can advance. The shaft 215 extends in the width direction of the vacuum cleaner body 7 in the stored state. In other words, the axis 215 and the rotation center line of the wheel 12 of the cleaner body 7 mounted on the pedestal 41 are arranged substantially in parallel. For this reason, when the speed reduction mechanism 44 falls, the cleaner main body 7 will become a use posture.

The support plate part 212 supports the cleaner main body 7 in contact with the main body case 11 which moves from a storage state to a use state, ie, falls down. The support plate part 212 is expanded in the width direction of the main body case 11 so as to stably support the moving cleaner body 7 . It is preferable that the support plate part 212 has a protective material, for example, raising on the surface which contact|connects the cleaner main body 7, for example.

In addition, when the support plate part 212 moves so that the cleaner main body 7 can proceed, that is, when the cleaner main body 7 falls from the stowed position to the use posture, the cleaner main body 7 is separated from the pedestal 41 . It becomes a descending inclined surface from the connection guide part 168 toward the surface to be cleaned so that it is easy to do it.

In addition, the speed reduction mechanism 44 may limit the moving speed with a so-called brake mechanism 218 . The speed reduction mechanism 44 may be provided with an oil damper (not shown) which accommodates hydraulic oil.

When the user tensions any part of the tube portion 8 of the vacuum cleaner 3 , preferably the handle operation tube 23 , or the grip portion 25 , the elastic member 213 increases the user's operating force and the cleaner body 7 . ), and moves the deceleration mechanism 44 (falls down). In accordance with this movement, the elastic member 213 accumulates energy for raising the speed reduction mechanism 44 .

In addition, the elastic member 213 is a torsion spring, for example. The elastic member 213 does not prevent the vacuum cleaner main body 7 resting on the pedestal 41 in the stowed position from being knocked down by the application of an external force, and also has a reduction mechanism ( 44) to stand-by position.

The charging terminal 46 of the station 2 is connectable to the vacuum cleaner main body 7 in the stowed state, and the connection with the cleaner main body 7 is released when the cleaner main body 7 falls into the use position. For this reason, the terminal cover 219 of the charging terminal 46 has a slit 219a facing upward of the station 2 , and the direction in which the vacuum cleaner 3 is separated from the station 2 , that is, in the direction of the station 2 . It has a slit 219b directed in the front direction (FIG. 24). The charging terminal 46 is connected to the charging electrode 19 of the cleaner body 7 inserted into these slits 219a and 219b.

By the way, the vacuum cleaner 3 can be used by lifting the vacuum cleaner main body 7 in a storage posture from the pedestal 41 above the station 2, and knocking down from the to-be-cleaned surface (floor surface) to a use posture. However, when using the vacuum cleaner 3, lifting and moving the cleaner body 7 is not convenient.

Then, the electric cleaning apparatus 1 which concerns on this embodiment inclines and knocks down the vacuum cleaner main body 7 of a storage posture, and use of the vacuum cleaner 3 can be started. For example, a user may hold a part of the pipe part 8 of the vacuum cleaner 3 , preferably the handle operation pipe 23 , or the grip part 25 and hold the dust collection hose 22 on the front of the station 2 . When pulling in the direction, the vacuum cleaner main body 7 collapses from the stowed posture to the use posture. The overturning fulcrum portion 202 functions as a fulcrum when the vacuum cleaner main body 7 shifts from the stowed posture to the use posture. That is, when a force sufficient to ride over the falling point part 202 is applied to the cleaner body 7 by the user's manipulation, the cleaner body 7 changes the direction with the falling point part 202 as a point, Transitions from the stowed posture to the use posture. At this time, the speed reduction mechanism 44 reduces the moving speed of the vacuum cleaner main body 7 falling down, thereby reducing the impact on the cleaner main body 7 . Further, when the auxiliary wheel 12b of the vacuum cleaner 3 is grounded, the suspension mechanism 56 ( FIG. 4 ) provided between the auxiliary wheel 12b and the handle 55 is grounded to the vacuum cleaner body 7 . fill the

When the user further tensions the pipe portion 8 , the cleaner body 7 is detached from the station 2 . That is, the user can start cleaning the vacuum cleaner 3 quickly and smoothly just by pulling the pipe part 8 .

Further, the electric cleaning device 1 knocks down the vacuum cleaner 3 toward the front of the station 2 by pulling the pipe 8 toward the front of the station 2, and also toward the front of the station 2 The vacuum cleaner 3 is removed from the station 2 by tensioning the tube 8 . Therefore, only the operation|movement of pulling the pipe part 8 toward the front of the station 2, the electric cleaning apparatus 1 changes the attitude|position of the vacuum cleaner main body 7 (posture change from a storage attitude|position to a use attitude|position), and use initiation is carried out in series.

In addition, the speed reduction mechanism 44 can be applied to a simple accommodating table that does not have these functions in addition to the station 2 having a charging function and a dust collecting function.

After the electric cleaning apparatus 1 according to the present embodiment generates an opening driving force and a closing driving force of the waste cover 92, and the secondary electric blower 50 stops the operation of generating a negative pressure to transport dust, , a driving source 169 for generating a closing driving force of the waste cover 92 to close the waste port 91 . Therefore, the electric cleaning apparatus 1 accommodates the electric vacuum cleaner 3 in the station 2, so that a user's individual operation for closing the waste cover 92 is not required, and the waste cover 92 is removed. can be closed

In addition, since the vacuum cleaner 1 can close the waste port 91 after the negative pressure by the secondary electric blower 50 becomes zero, the dust transferred from the vacuum cleaner 3 to the station 2 is discarded. The fear of getting caught between the sphere 91 and the waste cover 92 can be substantially eliminated. Therefore, the electric cleaning device 1 does not create a gap between the waste port 91 and the waste cover 92 , and the suction power of the electric cleaner 3 is unnecessarily consumed, or the primary dust container 13 . There is no dust leaking from the

Further, in the electric cleaning apparatus 1 according to the present embodiment, after the electric cleaner 3 is housed in the station 2 , the transfer of dust from the primary dust container 13 to the secondary dust container 49 is started. Until this occurs, the waste cover 92 is closed by maintaining the stop of the drive source 169 . Therefore, when the vacuum cleaner 1 is in a simple storage state in which no dust is transferred, the vacuum cleaner 3 is separated from the station 2 at any suitable time from the waste outlet 91 . There is no accidental leakage of dust.

Moreover, the electric cleaning apparatus 1 which concerns on this embodiment is equipped with the secondary electric blower 50 which generate|occur|produces a negative pressure, after the drive source 169 fully opens the waste cover 92. As shown in FIG. Therefore, the electric cleaning apparatus 1 prevents the negative pressure which the secondary electric blower 50 generate|occur|produces from acting on the waste cover 92 in the middle of opening, and the drive source 169 which drives the waste cover 92. , and to prevent unnecessary load from being applied to the power transmission path 175 that transmits the driving force from the driving source 169 to the waste cover 92 .

Further, the electric cleaning apparatus 1 according to the present embodiment is provided with an externally openable waste cover 92 that opens toward the outside of the primary dust container 13 . Therefore, the electric cleaning apparatus 1 prevents the waste cover 92 from accidentally closing during the conveyance of dust by the negative pressure which the secondary electric blower 50 generate|occur|produces.

Moreover, the electric cleaning apparatus 1 which concerns on this embodiment is equipped with the drive source 169 provided in the station 2 . Therefore, the electric cleaning device 1 can easily control the opening and closing of the waste cover 92 on the occasion of the vacuum cleaner 3 being accommodated in the station 2, and the start-up of the secondary electric blower 50 and timing can be appropriately controlled.

Moreover, the electric cleaning apparatus 1 which concerns on this embodiment is equipped with the secondary electric blower 50 provided in the station 2 . Therefore, the vacuum cleaner 1 can easily control the operation of the secondary electric blower 50 triggered by the vacuum cleaner 3 being accommodated in the station 2, and the driving timing of the drive source 169 and The operation timing of the secondary electric blower 50 can be appropriately linked.

For example, like the electric cleaning apparatus 1 which concerns on this embodiment, by providing both the drive source 169 and the secondary electric blower 50 in the station 2, the secondary electric blower 50 is started. The timing, that is, the start timing of dust transfer, and the opening/closing timing of the waste cover 92 can be collectively controlled from the station 2 side and appropriately linked.

Moreover, in the electric cleaning apparatus 1 which concerns on this embodiment, when the attachment detector 45 detects that the electric vacuum cleaner 3 is attached to the station 2, the secondary dust from the primary dust container 13 is It permits the transfer of dust to the container 48 . Therefore, the electric cleaning device 1 can easily link the driving timing of the drive source 169 and the driving timing of the secondary electric blower 50 with the vacuum cleaner 3 being housed in the station 2 as an opportunity. can

As described above, according to the electric cleaning device 1 according to the present embodiment, the waste cover 92 for blocking the waste port 91 for disposing of dust from the primary dust container 13 can be automatically opened and closed, In addition, there is little risk of dust getting caught between the waste cover 92 and the waste port 91, and the waste port 91 can be more reliably closed.
