Dust storage container for storing dust, vacuum cleaner provided with dust storage container, and cleaning appliance set provided with dust storage container or vacuum cleaner and recovery device for recovering dust from dust storage container

Abstract

A dust storage container according to the present disclosure includes: a peripheral wall portion having an inlet through which air flows; a bottom part for closing an opening at the lower end of the peripheral wall part; and a swinging connection part which allows the bottom part to swing downwards based on the dust collection force of the recovery source so as to form an open posture for opening the opening part of the peripheral wall part, and connects the bottom part to the peripheral wall part. The peripheral wall portion is configured so that air, which flows in through the inlet on the basis of the dust collection force of the recovery source, becomes a rotational flow that flows along the inner peripheral surface of the peripheral wall portion. The dust storage container further comprises a flow changing part which changes the flow direction of the air flow going to the swing connecting part in the rotational flow to another direction so as to prevent the dust contained in the rotational flow from being clamped in the gap between the bottom part in the open posture and the lower end part of the peripheral wall part.

Description

TECHNICAL FIELD

[0001] The present disclosure relates to a dust storage container that stores dust, a dust collector that has the dust storage container, and a cleaning tool set that has the dust storage container or the dust collector and a recovery device that recovers dust from the dust storage container. BACKGROUND

[0002] A cleaning tool set 300 is disclosed in Patent Literature 1. The cleaning tool set 300 has a dust collector 310 and a recovery device 320 configured to be able to hold the dust collector 310. Figure 28

[0003] The dust collector 310 has a suction source 311 that generates a suction force for suctioning dust, a substantially cylindrical dust storage container 312 that is provided on a lower side of the suction source 311, and a suction pipe 313 that is provided to extend in an up-and-down direction on a rear side of the dust storage container 312. Further, a suction nozzle 314 is attached to a lower end of the suction pipe 313.

[0004] The suction nozzle 314 is configured to allow dust on a floor to flow in together with air when the suction source 311 is operating. The suction pipe 313 forms a flow passage that allows dust and air that have flowed in from the suction nozzle 314 to flow upward, and is connected to a peripheral wall portion of the dust storage container 312. A connection portion at which the suction pipe 313 is connected to the peripheral wall portion of the dust storage container 312 is formed so as to communicate the flow passage of the suction pipe 313 with an internal space of the dust storage container 312. In detail, the connection portion is configured to allow air that has flowed in from the suction pipe 313 into the dust storage container 312 to flow along an inner peripheral surface of the peripheral wall portion 315 of the dust storage container 312 to become a rotational flow.

[0005] As shown in Figure 29 The dust storage container 312 has a bottom portion 316 that closes an opening portion of the lower end of the peripheral wall portion 315, and a swing connection portion 317 that connects the bottom portion 316 and the peripheral wall portion 315 while allowing the bottom portion 316 to swing downward.

[0006] As shown in Figure 28 The dust storage container 312 is configured to be attachable to the recovery device 320. The recovery device 320 has a support cylinder 321 configured to be able to allow a lower portion of the dust storage container 312 to be fitted, and the support cylinder 321 is provided to extend in the up-and-down direction. A recovery portion 322 that stores dust recovered from the dust storage container 312 is provided at a lower end of the support cylinder 321, and a recovery source 323 that generates a dust suction force downward by the recovery portion 322 and the support cylinder 321 is disposed on a lower side of the recovery portion 322.

[0007] When the user fits the dust storage container 312 to the upper end portion of the support cylinder 321 and operates the recovery source 323, based on the dust suction force of the recovery source 323, as shown in Figure 30 ​As shown, the bottom 316 of the dust storage container 312 is swung downward about the swing connection portion 317. As a result, the inside space of the dust storage container 312 is opened, and dust in the dust storage container 312 flows into the recovery portion 322 through the support cylinder 321.

[0008] During the transport of dust from the dust storage container 312 to the recovery portion 322, air flows into the suction nozzle 314 based on the suction force of the recovery source 323. Thereafter, this air flows into the dust storage container 312 through the suction pipe 313. The air flowing into the dust storage container 312 flows along the inner circumferential surface of the peripheral wall portion 315 to become a rotational flow, and flows out from the opening portion of the lower end of the peripheral wall portion 315 based on the suction force of the recovery source 323. The rotational flow flowing out from the opening portion of the lower end of the peripheral wall portion 315 causes the following problem.

[0009] That is, at the lower end portion of the peripheral wall portion 315, as Figure 30 As shown, the bottom 316 is swung downward, and a gap that is narrower toward the swing connection portion 317 is formed between the bottom 316 and the lower end portion of the peripheral wall portion 315. Also, since the rotational flow flowing at the lower end portion of the peripheral wall portion 315 contains an air current flowing toward the swing connection portion 317, dust contained in the rotational flow can be caught in the gap between the bottom 316 and the lower end portion of the peripheral wall portion 315. After the transport of dust from the dust storage container 312 to the recovery portion 322 is completed, the dust caught in the gap can interfere with the closing of the opening portion of the lower end of the peripheral wall portion 315 by the bottom 316.

[0012] Patent Document 1: International Patent Publication No. 2022 / 119097 SUMMARY

[0013] The present disclosure aims to provide a technology for preventing dust from being caught in a gap between a bottom of a dust storage container and a lower end portion of a peripheral wall portion when dust is transported from the dust storage container to a recovery device.

[0014] The dust storage container of the present disclosure is configured to be attachable to a recovery device in a state in which dust is stored, the recovery device having a recovery source that generates a suction force for suctioning the dust. The dust storage container includes a peripheral wall portion formed with an inflow port through which air flows in, a bottom portion that closes an opening portion of a lower end of the peripheral wall portion, and a swing connection portion that allows the bottom portion to swing downward based on the suction force of the recovery source to become an open attitude in which the opening portion of the peripheral wall portion is opened, and connects the bottom portion to the peripheral wall portion. The peripheral wall portion is configured so that air that flows in through the inflow port based on the suction force of the recovery source becomes a rotational flow that flows along an inner peripheral surface of the peripheral wall portion. The dust storage container further includes a flow change portion that suppresses a case in which dust contained in the rotational flow is pinched in a gap between the bottom portion in the open attitude and a lower end portion of the peripheral wall portion by changing a flow direction of an air current in the rotational flow to another direction.

[0015] The dust collector of the present disclosure includes a suction source that generates a suction force for suctioning dust, a suction pipe that forms a flow passage through which dust flows based on the suction force of the suction source, and the above-described dust storage container. The dust storage container is connected to the suction pipe in a manner such that the suction force of the suction source acts on the flow passage of the suction pipe through the dust storage container when the suction source is operating, and allows dust flowing in the flow passage of the suction pipe to flow into the dust storage container through the inflow port.

[0016] The cleaning tool set of the present disclosure includes the above-described dust storage container, and a recovery device configured to be able to attach the dust storage container, and to recover dust in the dust storage container in a state in which the dust storage container is attached. The recovery device has a support cylinder that supports the dust storage container, and is formed with a flow passage that extends in an up-down direction in a manner such that dust falling from the dust storage container flows, and a recovery source that generates a suction force that holds a bottom portion of the dust storage container supported by the support cylinder in an open attitude, and that suctions dust from the dust storage container and causes the dust to fall into the support cylinder.

[0017] The cleaning tool set of the present disclosure includes the above-described dust collector, and a recovery device configured to be able to attach the dust collector, and to recover dust in the dust storage container in a state in which the dust collector is attached. The recovery device has a support cylinder that supports the dust storage container, and is formed with a flow passage that extends in an up-down direction in a manner such that dust falling from the dust storage container flows, and a recovery source that generates a suction force that holds a bottom portion of the dust storage container supported by the support cylinder in an open attitude, and that suctions dust from the dust storage container and causes the dust to fall into the support cylinder.

[0018] The above-described technology can prevent dust from being pinched in a gap between a bottom portion and a lower end portion of a peripheral wall portion of a dust storage container when dust is transported from the dust storage container to a recovery device. BRIEF DESCRIPTION OF DRAWINGS

[0049] Hereinafter, embodiments of the dust collection container, vacuum cleaner, and cleaning appliance assembly will be described in detail with reference to the accompanying drawings. However, to facilitate understanding by those skilled in the art, detailed descriptions of well-known matters or repetitive descriptions of substantially the same components may be omitted. Furthermore, the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand this disclosure and are not intended to limit the subject matter of the claims.

[0050] <First Embodiment>

[0051] Figure 1 This is a side view of a stick vacuum cleaner 100. (Refer to...) Figure 1 Let's explain vacuum cleaner 100.

[0052] (The overall structure of a vacuum cleaner)

[0053] Vacuum cleaner 100 includes: a vacuum cleaner body 110, with a built-in suction source 111 that generates suction force for sucking up dust; and a dust collection container 200, which is installed on the lower side of the vacuum cleaner body 110. Inside the vacuum cleaner body 110, a battery 114 is housed above the suction source 111. The battery 114 stores electricity for operating the suction source 111 and is electrically connected to the suction source 111. The suction source 111 is configured to suck air from the dust collection container 200, and for example, it may include: a motor that receives power from the battery 114 to generate rotational force; and rotating blades configured to generate an upward airflow when rotating based on the motor.

[0054] A filter 112 is disposed between the vacuum cleaner body 110 and the dust collection container 200, which allows air to pass through while capturing dust contained in the air. Furthermore, a grip 113, configured to be held by a user, is disposed on the front side of the vacuum cleaner body 110 and the dust collection container 200; and a suction tube 120, having a flow channel 123 for allowing dust drawn by the suction source 111 to flow. The dust drawn by the suction source 111 flows towards the dust collection container 200 through the flow channel 123.

[0055] The suction tube 120 is configured to extend vertically below the grip portion 113. Specifically, the suction tube 120 has: a base tube portion 121 integrally formed with the vacuum cleaner body 110 and the grip portion 113; and an extension tube portion 122 extending downward from the base tube portion 121. Within the base tube portion 121, a flow channel 123 bends towards the dust collection container 200. The extension tube portion 122 can be detached from the base tube portion 121. A suction nozzle 130 is mounted at the lower end of the extension tube portion 122. The suction tube 120 is configured to extend downward relative to the grip portion 113, the vacuum cleaner body 110, and the dust collection container 200, and has a length that allows the suction nozzle 130 to contact the ground even without the user bending over. A suction port 131 is formed on the front side of the lower side of the suction nozzle 130, which allows dust on the ground to be sucked in by the suction force of the suction source 111. A space is formed in the suction nozzle 130 that connects the suction port 131 to the flow channel 123.

[0056] The dust storage container 200 is configured to store dust drawn in by the suction force of the suction source 111, such as... Figure 2 As shown, it has: a container portion 210 opening upwards; and a top cover portion 220 that covers the opening at the upper end of the container portion 210. The upper part of the top cover portion 220 is configured to hold... Figure 1 The filter 112 shown has a plurality of through holes 221 formed in the upper cover 220, which extend through the upper cover 220 in the vertical direction. Figure 1When the suction source 111 shown is working, the air inside the container section 210 flows out through these through holes 221.

[0057] The container portion 210 has a generally cylindrical peripheral wall portion 211, and an inlet 239 is formed in the peripheral wall portion 211, opening in a tangential direction to the inner peripheral surface of the peripheral wall portion 211. The inlet 239 and... Figure 1 The flow channel 123 of the base tube 121 shown is connected, and when the suction source 111 is working, air containing dust flows into the container section 210 through the inlet 239. This air becomes a swirling flow along the inner circumferential surface of the peripheral wall section 211.

[0058] The aforementioned upper cover 220 is installed at the upper end of the peripheral wall portion 211, and on the other hand, at the lower end of the peripheral wall portion 211, such as... Figure 3 As shown, a bottom 212 is mounted via a swing connection 213. The lower end of the peripheral wall 211 has an opening that is a downward-opening dust outlet 217 that allows dust accumulating in the dust collection container 200 to fall down. Figure 3 In the middle, the dust outlet 217 is closed based on the bottom 212. The swing connection 213 allows the bottom 212 to... Figure 3 The closed posture shown tilts downward around the swing connection 213 to become Figure 4 The bottom 212 is in the open position as shown. When the bottom 212 is in the open position, the dust outlet 217 is opened, and the dust in the dust storage container 200 can fall through the dust outlet 217. In addition, the suction pipe 120 is provided extending on the front side of the dust storage container 200, and the tilting of the bottom 212 is not obstructed by the suction pipe 120.

[0059] In container section 210, such as Figure 3 The diagram shows a cylindrical filter section 230 that tapers towards the bottom 212. A through-hole 221 formed in the upper cover 220 communicates with the internal space of the filter section 230.

[0060] Filter section 230 Figure 5 The filter section 230 is configured to be approximately coaxial with the container section 210 and has a generally circular cross-section. An annular space 232 is formed between the filter section 230 and the inner circumferential surface of the peripheral wall section 211 of the container section 210, and the aforementioned swirling flow flows in the annular space 232.

[0061] The filter section 230 has multiple vents (not shown) of varying sizes, each capable of trapping dust while allowing air to flow into the annular space 232. For example, the filter section 230 can be formed of a filter screen. Figure 1When the suction source 111 is activated, air flows in through the inlet 239 and forms a swirling flow within the annular space 232 of the container section 210. Dust contained in the air flowing into the container section 210, due to the centrifugal force of the swirling flow, tends to flow more near the inner circumferential surface of the peripheral wall 211 of the container section 210 than near the filter section 230. Therefore, clogging of the vent holes in the filter section 230 is less likely. The air flowing near the filter section 230 flows into the interior of the filter section 230 through the vent holes. Furthermore, air can flow upwards through the through-hole 221 of the upper cover section 220.

[0062] like Figure 6 As shown, a partition plate 233 is installed in the filter section 230. The partition plate 233 is configured to extend approximately half the circumference of an annular space 232 from the lower edge of the inlet 239 along the flow direction of the swirling flow. The partition plate 233 is positioned approximately parallel to the bottom 212 at a position above the gap, dividing the annular space 232 vertically. In the following description, the space located below the partition plate 233 (i.e., between the partition plate 233 and the bottom 212) is referred to as the "dust collection space 234". The dust collection space 234 is a space for accumulating dust. In the following description, the space extending circumferentially from the inlet 239 to the downstream end 241 of the partition plate 233 in the flow direction of the swirling flow is referred to as the "upstream space 271". The partition 233 separates the upstream space 271 from the dust storage space 234 vertically, preventing dust accumulated in the dust storage space 234 from flying into the upstream space 271.

[0063] like Figure 7 As shown, a guide space 243 is formed on the downstream side of the upstream space 271 to facilitate the flow of dust contained in the swirling flow to the dust collection space 234. To demarcate the upper end of the guide space 243, a guide section 237 is installed on the filter section 230. The guide section 237 is plate-shaped, and its upstream end 238 in the flow direction of the swirling flow is located approximately directly above the downstream end 241 in the flow direction of the swirling flow of the partition plate 233. The swirling flow generated in the upstream space 271 flows into the area between the upstream end 238 of the guide section 237 and the downstream end 241 of the partition plate 233.

[0064] The guide section 237 is configured to extend circumferentially around the filter section 230 while tilting downwards (towards the bottom 212 side) from the upstream end 238, and as... Figure 8It is connected to the partition plate 233 as shown. That is, the partition plate 233 is configured to extend circumferentially from the downstream end of the guide portion 237 in the flow direction of the swirling flow. The swirling flow is guided downward (i.e., to the bottom 212 side) due to the inclination of the lower side of the guide portion 237. In the following description, the lower side of the guide portion 237 will be referred to as the "guide surface 242". The aforementioned guide space 243 is the space between the guide surface 242 and the bottom 212, and it communicates with the dust collection space 234 on the lower side of the partition plate 233.

[0065] (A structure used to keep the bottom in a closed position)

[0066] like Figure 3 As shown, in order to keep the bottom 212 in a closed position, a force-applying part 214 is provided to apply a force to the bottom 212 in a closed position. In this embodiment, the force-applying part 214 has a torsion spring installed in the swing connection part 213, and the swing connection part 213 passes through the coil portion of the torsion spring.

[0067] On the opposite side of the swing connection 213 relative to the dust outlet 217, a locking claw 219 is provided for locking the bottom 212 in a closed position. The locking claw 219 has a locking operation part 222 that can be operated by a user; and a locking part 223 that is formed to protrude from the locking operation part 222 and can engage with the outer edge of the bottom 212. In the following description, the state in which the locking part 223 engages with the outer edge of the bottom 212 in a closed position and prevents the bottom 212 from tilting downward is referred to as the "locked state".

[0068] The engaging claw 219 can move towards Figure 3 The arrow is oscillatingly mounted on the peripheral wall 211. If the user presses the locking operation part 222 from below upwards while simultaneously causing the engaging claw part 219 to... Figure 3 When the arrow swings in the direction of the lock, the engagement between the bottom 212 and the locking part 223 is released. In the following description, the state of the locking part 223 at this time will be referred to as the "unlocked state". Furthermore, the engaging claw 219 is applied in a direction that engages with the bottom 212 based on the coil spring 215. Figure 3 The force acting in the opposite direction of the arrow.

[0069] like Figure 2 As shown, a receiving recess 216 for receiving a locking claw portion 219 is formed at the lower part of the peripheral wall portion 211. When the locking claw portion 219 is engaged with the bottom 212, the locking operation portion 222 is recessed into the receiving recess 216, thereby preventing accidental contact with the locking operation portion 222.

[0070] (A component used to assist in the recovery of dust from the dust storage container)

[0071] Dust collection container 200 or vacuum cleaner 100 and Figure 9 The shown recycling device 400 together constitutes the cleaning appliance assembly 500. Dust in the dust storage container 200 is sucked out by the recycling device 400 and recycled back to the recycling device 400. During dust recycling performed by the recycling device 400, the bottom 212 as shown Figure 10 It swings downwards as shown, opening the dust discharge port 217. At this time, the air flowing in from the inlet 239 becomes a swirling flow within the dust storage container 200.

[0072] exist Figure 10 In the illustrated state, a gap 224 is formed between the bottom 212 and the lower end of the peripheral wall 211, and the gap 224 narrows as it approaches the swing connection 213. Therefore, when dust in the dust collection space 234 is discharged from the dust outlet 217 by the swirling flow, the dust contained in the airflow heading towards the swing connection 213 in the swirling flow may become trapped in the gap 224 between the bottom 212 and the lower end of the peripheral wall 211. To prevent dust from being trapped in the gap 224, the dust storage container 200 has a flow-changing section 225 that protrudes inward from the lower part of the inner peripheral surface of the peripheral wall 211. The flow-changing section 225 is configured to change the flow direction of the swirling flow so that the swirling flow flows inward from the gap 224 on the upstream side of the swing connection 213. Furthermore, the flow change section 225 has a plate-shaped member that is inclined relative to the flow direction of the swirling flow, thereby preventing dust contained in the swirling flow from being stuck by the flow change section 225.

[0073] (Overall structure of the recycling device)

[0074] like Figure 9 As shown, the recycling device 400 is configured to accommodate a dust storage container 200. Specifically, the recycling device 400 includes: a support plate 410 that is generally rectangular in shape when viewed from above; a frame 420 disposed on the support plate 410; a support cylinder 430 extending upward from the upper side of the frame 420; and a tube holding portion 440 disposed on the front portion of the support cylinder 430. The upper end of the support cylinder 430 is configured to accommodate the dust storage container 200, and the support cylinder 430 supports the dust storage container 200 during dust recycling operations from the dust storage container 200 to the recycling device 400. Furthermore, as... Figure 11 As shown, the support cylinder 430 is formed with a flow channel 431 extending in the vertical direction to allow dust discharged from the dust outlet 217 of the dust storage container 200 to fall down.

[0075] like Figure 12As shown, a retaining groove 441 is formed on the tube retaining portion 440, opening forward and extending vertically. The retaining groove 441 has a shape complementary to the rear portion of the base tube portion 121 of the vacuum cleaner 100. By providing the tube retaining portion 440, the user is prompted to position the suction tube 120 of the vacuum cleaner 100 to the front side of the frame 420 and support cylinder 430 of the recovery device 400 and to insert the base tube portion 121 into the retaining groove 441. That is, the vacuum cleaner 100 is prompted to be installed in the recovery device 400 in a specified orientation.

[0076] If the user inserts the base tube 121 into the retaining groove 441, the suction tube 120 will then... Figure 11 As shown, it is held in a position extending downwards along the front side of the support tube 430 and the frame 420. To support the suction nozzle 130 mounted at the lower end of the suction tube 120, as... Figure 12 As shown, the front portion of the support plate 410 protrudes forward relative to the frame 420, and a support base 411 is provided on this front portion. The support base 411 protrudes upward relative to the upper side of the support plate 410, as shown... Figure 11 As shown, the rear of the suction nozzle 130 is mounted on the support base 411. The suction port 131 of the suction nozzle 130 opens in the air at the front of the support base 411.

[0077] The housing 420 includes: a collection source 421 that generates suction force to draw dust from the dust collection container 200 of the vacuum cleaner 100; and a collection section 422 that stores the dust drawn from the dust collection container 200. The collection section 422 is positioned above the collection source 421, and a filter 423 is disposed between the collection section 422 and the collection source 421, which allows air to pass through while capturing dust. The collection source 421 is connected to the collection section 422 via the filter 423.

[0078] The recycling source 421 and recycling section 422 are disposed within the frame 420 at a position relative to the support cylinder 430. To allow communication between the internal space of the recycling section 422 and the flow channel 431 of the support cylinder 430, a connecting cylinder 424 is provided, extending forward from the front side of the recycling section 422 in a generally horizontal manner. While the support cylinder 430 extends vertically, the connecting cylinder 424 is positioned generally horizontally; therefore, the connection portion 425 between the support cylinder 430 and the connecting cylinder 424 is curved. The axial length of the connecting cylinder 424 is shorter than the axial length of the support cylinder 430 to prevent the frame 420 from becoming excessively large in the front-rear direction.

[0079] Recycling source 421 is configured as follows: Figure 3When the locking part 223 is in the unlocked state, it generates a suction force sufficient to resist the force-applying part 214, causing the bottom 212 to tilt downwards and keeping the bottom 212 in an open position, and to suck out the dust from the dust collection container 200. The recovery source 421 may, for example, have: a motor that generates rotational force; and a rotating blade configured such that if the motor rotates and drives the rotating blade, the rotating blade generates a downward airflow.

[0080] The support cylinder 430 has an outer cylinder 432 extending vertically, and an inner cylinder 433 extending vertically within the outer cylinder 432 to form the aforementioned flow channel 431. The inner cylinder 433 may have a constant inner diameter along its entire length. The axial length of the outer cylinder 432 is set such that the lower end of the dust collection container 200 is embedded when the suction nozzle 130 is mounted on the support block 411. In this state, the battery 114 and the suction source 111 within the vacuum cleaner body 110 are arranged vertically above the support cylinder 430 and the dust collection container 200, and are located on the axis of the support cylinder 430.

[0081] The inner cylinder 433 is positioned such that its upper end is below the upper end of the outer cylinder 432. More specifically, the inner cylinder 433 is disposed within the outer cylinder 432 such that a tilting space 434 is formed between the upper end of the inner cylinder 433 and the upper end of the outer cylinder 432, allowing the bottom 212 to tilt downwards. For example... Figure 13 As shown, the lower part of the dust storage container 200 is embedded in the upper part of the tilting space 434.

[0082] With the dust container 200 embedded in the tilting space 434, the dust container 200 and the vacuum cleaner body 110 of the vacuum cleaner 100 are supported by the outer cylinder 432 and the frame 420. At this time, the grip portion 113 and the suction tube 120 on the front side of the dust container 200 and the vacuum cleaner body 110 are supported by the support block 411. In addition, the rear part of the suction nozzle 130 is placed on the support block 411, but the front part of the suction nozzle 130 is in a state of being suspended upward relative to the support plate 410, located in front of the support block 411. To achieve this state, the axial length of the outer cylinder 432 is set such that the suction nozzle 130 is suspended relative to the support plate 410 when the dust container 200 is embedded in the tilting space 434. Moreover, the height of the support block 411 is set such that the upper end of the support block 411 contacts the rear part of the suction nozzle 130 when the dust container 200 is embedded in the tilting space 434.

[0083] In this embodiment, the vacuum cleaner 100 is configured such that when the user holds the suction tube 120 in the tube holding portion 440 and inserts the lower end portion of the dust collection container 200 into the tilting space 434, the engaging claw portion 219 is located at the rear end of the tilting space 434. Furthermore, the outer cylinder 432 has a stepped portion 435 located opposite the engaging claw portion 219 of the dust collection container 200 inserted into the tilting space 434. A thin plate-shaped release portion 436 is vertically provided from the stepped portion 435 upwards. When the lower end portion of the dust collection container 200 is inserted into the tilting space 434, the release portion 436 contacts the locking operation portion 222 of the engaging claw portion 219, applying an upward force to the locking operation portion 222. As a result, the engaging claw portion 219... Figure 3 The posture shown becomes Figure 13 In the posture shown, the engagement between the locking part 223 and the bottom 212 is released. That is, the locking part 223 is set to the unlocked state based on the release part 436.

[0084] (The action of the vacuum cleaner)

[0085] When the suction source 111 is operational, air within the dust collection container 200 is drawn out through the filter section 230 based on the suction force of the suction source 111. An amount of air equivalent to the amount drawn out of the dust collection container 200 is drawn into the suction nozzle 130, and dust from the ground flows into the suction nozzle 130 along with this air. Furthermore, dust containing dust flows in the flow channel 123 of the suction pipe 120 and flows into the dust collection container 200 through the inlet 239.

[0086] Since the inlet 239 opens tangentially to the inner circumferential surface of the peripheral wall 211 of the container section 210, the air flowing into the container section 210 from the inlet 239 flows along the inner circumferential surface of the peripheral wall 211. Furthermore, this air forms a swirling flow during its flow in the upstream space 271 within the container section 210. Due to the centrifugal force of the swirling flow, more dust contained within the swirling flow flows near the inner circumferential surface of the peripheral wall 211 of the container section 210 than near the filter section 230, resulting in less dust adsorbed onto the filter section 230. Therefore, the air flowing near the filter section 230 is not obstructed by dust and flows into the filter section 230 through the vents provided on the filter section 230. The air flowing into the filter section 230 flows out of the dust storage container 200 through the through-hole 221 formed on the upper cover 220. Furthermore, even if the air passing through the through-hole 221 contains fine dust particles, these fine dust particles will be captured by the filter 112 provided on the upper cover 220.

[0087] After passing through the upstream space 271, the swirling flow enters the guiding space 243. If the dust contained in the swirling flow reaches the vicinity of the guiding surface 242 of the guiding section 237, it is guided towards the bottom 212 of the container section 210 as the guiding surface 242 is inclined. Since the guiding space 243 is connected to the dust collection space 234, the dust flows from the guiding space 243 into the dust collection space 234.

[0088] While the user is cleaning with the vacuum cleaner 100 as described above, the engaging claw 219 is submerged in the receiving recess 216, making it difficult for the user to accidentally come into contact with the engaging claw 219. Therefore, it is difficult to accidentally disengage the bottom 212 from the locking part 223.

[0089] If the user accidentally comes into contact with the engaging claw 219 during cleaning, thereby disengaging the bottom 212 from the locking part 223, the bottom 212 will also be subjected to a closing force based on the force application part 214. Therefore, it prevents dust accumulated in the dust storage container 200 from falling out of the dust outlet 217 during cleaning.

[0090] (The operation of the recycling device)

[0091] After finishing the cleaning operation, the user installs the vacuum cleaner 100 into the recycling device 400. Specifically, the user positions the suction tube 120 of the vacuum cleaner 100 against the front of the frame 420 and support cylinder 430 of the recycling device 400. In this state, the user inserts the base end 121 of the suction tube 120 into the retaining groove 441 of the tube retaining part 440 while simultaneously inserting the lower end of the dust collection container 200 into the upper end of the support cylinder 430. If the user pushes the lower end of the dust collection container 200 down into the tilting space 434 of the upper end of the support cylinder 430, the release part 436 contacts the locking operation part 222 of the engaging claw part 219, and the locking operation part 222 becomes... Figure 13 The posture shown. As a result, the locking part 223 of the engaging claw 219 becomes unlocked, and the engagement between the locking part 223 and the bottom 212 is released. In this state, the bottom 212 of the dust storage container 200 is maintained in a closed posture based on the force application part 214.

[0092] Subsequently, when the recycling source 421 operates, its suction force acts on the bottom 212 of the dust storage container 200 through the recycling section 422, the connecting cylinder 424, and the support cylinder 430. Based on the suction force of the recycling source 421, the bottom 212 tilts downwards against the force applied by the force-applying section 214, thus becoming open. As a result, the dust outlet 217 of the dust storage container 200 is opened. The suction force of the recycling source 421 draws out the dust from the dust storage container 200 while maintaining the open position of the bottom 212. The dust flows into the recycling section 422 through the support cylinder 430 and the connecting cylinder 424 and accumulates within the recycling section 422.

[0093] Since the flow channel 431 of the support cylinder 430 extends in the vertical direction, the dust is affected by both the suction force of the recovery source 421 and gravity during its passage through the support cylinder 430. Because the dust discharge from the dust storage container 200 utilizes both the suction force of the recovery source 421 and gravity, an excessively high suction capacity is not required for the recovery source 421.

[0094] In the support cylinder 430, dust flows downwards not only due to the suction force of the recovery source 421 but also due to gravity, thus making dust blockage unlikely. On the other hand, since the connecting cylinder 424 is in a roughly horizontal position, the flow direction of dust is not the same as the direction of gravity, requiring the suction force of the recovery source 421 to guide the dust into the recovery section 422. However, the connecting cylinder 424 is located close to the recovery source 421 relative to the support cylinder 430, so the suction force acting on the connecting cylinder 424 is higher than that acting on the support cylinder 430. Therefore, the suction force of the recovery source 421 alone is sufficient to allow the dust in the connecting cylinder 424 to flow into the recovery section 422. Furthermore, since the connecting cylinder 424 has a shorter axial length than the support cylinder 430, even if the suction force of the recovery source 421 alone is used to guide the dust in the connecting cylinder 424 into the recovery section 422, dust blockage is unlikely to occur in the connecting cylinder 424.

[0095] When the dust collection source 421 sucks out dust from the dust storage container 200, the suction force of the collection source 421 acts on the suction port 131 of the nozzle 130 through the collection section 422, connecting cylinder 424, support cylinder 430, dust storage container 200, and suction pipe 120. At this time, the suction port 131 is not covered by the support block 411 supporting the nozzle 130 and is open in the air. Therefore, the resistance to the air flowing into the suction port 131 is small, allowing a large amount of air to flow into the nozzle 130. Moreover, this air flows into the dust storage container 200 through the suction pipe 120 and the inlet 239. At this time, since the inlet 239 opens in the tangential direction to the inner circumferential surface of the peripheral wall 211 of the dust storage container 200, a swirling flow is generated inside the dust storage container 200.

[0096] The swirling flow circulates within the dust storage container 200 along the inner circumferential surface of the peripheral wall 211, flowing towards the dust discharge port 217 and reaching the lower part of the dust storage container 200. If the flow change section 225 is not provided at the lower part of the dust storage container 200, a portion of the swirling flow will... Figure 14 The flow is as shown by the dotted line. In this case, the swirling flow may flow in the gap 224 between the lower end of the peripheral wall 211 and the bottom 212. This gap 224 narrows as it approaches the swing connection 213. If larger dust particles flow with the swirling flow, the dust particles will flow in the gap 224 at the position away from the swing connection 213, but they will approach the swing connection 213 as they are gradually compressed by the lower end of the peripheral wall 211 and the bottom 212. Thus, the dust particles may be in a state of being clamped by the lower end of the peripheral wall 211 and the bottom 212 near the swing connection 213. This dust particles may prevent the bottom 212 from returning to the closed position after the dust is recovered from the dust storage container 200 to the recovery device 400.

[0097] On the other hand, if a flow change section 225 is provided at the lower part of the dust storage container 200, the vortex will... Figure 14 The flow is as shown by the solid line. The flow-changing section 225 protrudes inward from the lower part of the inner circumferential surface of the peripheral wall 211 on the upstream side of the gap 224, thus changing the flow direction of the swirling flow that flows along the inner circumferential surface of the peripheral wall 211 to the inward side. That is, the swirling flow, based on the flow-changing section 225, flows towards the inward side of the dust storage container 200 on the upstream side of the gap 224. As a result, most of the dust contained in the swirling flow, such as... Figure 14 As shown by the solid line, the material can flow inwards from the gap 224, thus preventing dust from being trapped in the gap 224.

[0098] Furthermore, the dust flowing with the swirling current collides with the flow change section 225. However, since the flow change section 225 is tilted downstream of the swirling current, the dust will not remain stuck on the flow change section 225 and can flow downstream. Therefore, it is unlikely that the flow change section 225 itself will obstruct the discharge of dust from the dust storage container 200.

[0099] If the user stops collecting the source 421, the suction force acting on the bottom 212 disappears. The bottom 212 then swings upwards based on the force-applying part 214, returning to the closed position. At this time, because the flow-changing part 225 prevents dust from getting trapped in the gap 224 between the bottom 212 and the lower end of the peripheral wall 211, the bottom 212 returns to the closed position without being obstructed by such dust, thus sealing the dust outlet 217.

[0100] The user can maintain the vacuum cleaner 100 installed in the recycling device 400 after stopping the recycling source 421. That is, the user can use the recycling device 400 to store the vacuum cleaner 100. At this time, the vacuum cleaner 100's battery 114 and suction source 111 are arranged on the upper side of the dust storage container 200 in an axial direction with the dust storage container 200. Therefore, the weight of the battery 114 and suction source 111 is unlikely to cause the support cylinder 430 and thus the recycling device 400 to tip over.

[0101] The battery 114 and the suction source 111 are mounted on the shaft of the support cylinder 430. Meanwhile, the suction pipe 120, the suction nozzle 130, and the grip 113 are positioned at the front of the support cylinder 430. Therefore, the weight of the suction pipe 120, the suction nozzle 130, and the grip 113 causes the support cylinder 430, and consequently the recovery device 400, to tip forward. However, since the recovery unit 422 and the recovery source 421 are positioned opposite the support cylinder 430 (i.e., at the rear of the support cylinder 430), their weight prevents the recovery device 400 from tipping forward.

[0102] When restarting the cleaning operation, the user removes the vacuum cleaner 100 from the collection device 400. At this time, the dust container 200 is separated from the support cylinder 430. As the dust container 200 separates from the support cylinder 430, the release part 436 disengages from the receiving recess 216 and becomes non-contact with the locking operation part 222. In this state, since the pressure from the release part 436 on the locking operation part 222 disappears, the release part 436 is pulled back by the coil spring 215. Figure 3 On the opposite side of the arrow, the locking part 223 engages with the outer edge of the bottom 212. That is, the locking part 223 is in a locked state, locking the bottom 212. Therefore, the cleaning operation can be restarted with the bottom 212 locked in the closed position.

[0103] In the above embodiment, the engaging claw 219 is recessed within the receiving recess 216, making it difficult for the user to accidentally come into contact with the engaging claw 219. However, the receiving recess 216 can be omitted. In this case, it is preferable that the engaging claw 219 is installed in the dust storage container 200 in a location that is difficult for the user to access.

[0104] Figure 9 The vacuum cleaner 100 shown has a locking claw portion 219, but the bottom 212 is subjected to force in the closed position based on the force-applying portion 214, so the locking claw portion 219 can be omitted. In this case, the recycling device 400 may not have a release portion 436.

[0105] exist Figure 9In this configuration, the vacuum cleaner 100 is mounted on the recovery device 400 with the nozzle 130 resting on the support block 411. However, the user can also remove the nozzle 130 from the lower end of the suction pipe 120 and then mount the vacuum cleaner 100 on the recovery device 400. When the vacuum cleaner 100 is mounted on the recovery device 400, the lower end of the suction pipe 120 is positioned higher than the nozzle 130 and is therefore not covered by the support block 411. Thus, even when the nozzle 130 is removed from the vacuum cleaner 100, air will not experience high resistance at the lower end of the suction pipe 120, allowing it to flow into the flow channel 123 and sweep dust from the dust collection container 200 to the recovery device 400.

[0106] Vacuum cleaner 100 can be fitted with shapes and... Figure 9 The suction nozzle 130 shown is different from other suction nozzles. For example, it can be... Figure 15 The nozzle 132 shown or Figure 16 The nozzle 133 shown is mounted at the lower end of the suction tube 120. In this case, the axial length of these nozzles 132, 133 is preferably set such that when the vacuum cleaner 100 is installed on the recycling device 400, the suction port 131 of these nozzles 132, 133 is open in the air above the support block 411.

[0107] In the recycling apparatus 400 of the first embodiment, the recycling section 422 is disposed behind the support cylinder 430, and is therefore connected to the support cylinder 430 via the connecting cylinder 424. However, the recycling section 422 may be disposed directly below the support cylinder 430. In this case, the connecting cylinder 424 is not required, and the support cylinder 430 may be configured to extend directly upward from the recycling section 422. If the support cylinder 430 is provided to extend vertically upward from the recycling section 422, dust can fall directly from the dust storage container 200 into the recycling section 422.

[0108] In the recycling apparatus 400 of the first embodiment, the inner cylinder 433 of the support cylinder 430 has a constant inner diameter along its entire length. Alternatively, the inner diameter of the inner cylinder 433 can gradually increase as it descends. In this case, dust passing through the upper end of the inner cylinder 433 will not be stuck in the middle of the inner cylinder 433 and can fall to the connecting portion 425 connected to the connecting cylinder 424. In this case, the inner diameter of the connecting cylinder 424 can gradually increase as it moves from the connecting portion 425 to the recycling portion 422. In this case, dust is prevented from clogging the connecting cylinder 424 during its journey from the connecting portion 425 to the recycling portion 422.

[0109] <Second Implementation>

[0110] The recycling device 400 can not only be used to collect dust from the vacuum cleaner 100, but can also be configured to charge the vacuum cleaner 100. For example, asFigure 17 As shown, the recycling device 400 includes a cable 450 forming a path for the transmission of power from an external power source. Furthermore, the recycling device 400 includes output terminals 451 and 452; and a control circuit 453 electrically connected to the cable 450, output terminals 451 and 452, and recycling source 421. The control circuit 453 is disposed within a housing 420. The cable 450 is configured to extend outward from the housing 420 and is electrically connected to the control circuit 453 within the housing 420.

[0111] Output terminals 451 and 452 are disposed in retaining groove 441. Specifically, retaining groove 441 has an upper portion 442 that extends obliquely downward from the upper end portion of support cylinder 430, and a lower portion 443 that extends substantially parallel to support cylinder 430. Output terminals 451 and 452 protrude upward from the upper portion 442 of retaining groove 441.

[0112] like Figure 18 As shown, input terminals 265 and 266 are provided on the portion of the outer side of the base tube 121 of the vacuum cleaner 100 that is embedded in the upper part 442 of the retaining groove 441. Figure 19 As shown, power lines 267 and 268, which form a path for transmitting power to the battery 114 inside the vacuum cleaner body 110, are connected to input terminals 265 and 266.

[0113] like Figure 20 As shown, when the base tube 121 of the vacuum cleaner 100 is inserted into the retaining groove 441, the input terminals 265 and 266 press the output terminals 451 and 452 downwards, and the output terminals 451 and 452 are inserted into the tube retaining part 440 while undergoing elastic deformation. Moreover, if the vacuum cleaner 100 is removed from the retaining groove 441, the output terminals 451 and 452 return to their original state and protrude within the retaining groove 441.

[0114] like Figure 19 As shown, output terminals 451 and 452 are connected to control circuit 453. Control circuit 453 includes converter 454, drive circuit 455, and contact detection circuit 456.

[0115] The converter 454 is connected to the cable 450 and converts the AC power transmitted through the cable 450 into DC power. The DC power is transmitted from the converter 454 to the output terminals 451 and 452 through power supply paths 457 and 458, and is output from the output terminals 451 and 452.

[0116] Power supply path 457 is connected to converter 454 and output terminal 451. Additionally, power supply path 458 is connected to converter 454 and output terminal 452. Contact detection circuitry 456 is configured on power supply path 458.

[0117] like Figure 19 As shown, when the output terminals 451 and 452 are in contact with the input terminals 265 and 266, power can be supplied from the converter 454 to the battery 114, and current flows to the power supply paths 457 and 458. On the other hand, if the output terminals 451 and 452 are not in contact with the input terminals 265 and 266, current does not flow to the power supply paths 457 and 458.

[0118] The contact detection circuit 456 is configured to detect whether the vacuum cleaner 100 is installed in the recycling device 400 based on such current changes. Furthermore, if the contact detection circuit 456 detects current flowing in the power supply path 458, it determines that the vacuum cleaner 100 is installed in the recycling device 400 and outputs a drive command. Conversely, if no current is detected flowing in the power supply path 458, the contact detection circuit 456 determines that the vacuum cleaner 100 is not installed in the recycling device 400. In this case, no drive command is output.

[0119] The drive circuit 455 is configured to receive AC power via cable 450 and to drive the recycling source 421 using this AC power during a specified period. Furthermore, the driving of the recycling source 421 based on the drive circuit 455 is executed conditionally upon the drive circuit 455 receiving a drive command from the contact detection circuit 456. Therefore, if the drive circuit 455 does not receive a drive command, the drive circuit 455 does not drive the recycling source 421, and the recycling source 421 remains in a stopped state.

[0120] When the user is performing a cleaning operation using the vacuum cleaner 100, the vacuum cleaner 100 is disconnected from the recycling device 400, and current does not flow to the power supply path 458. Therefore, the contact detection circuit 456 does not output a drive command, and the drive circuit 455 does not drive the recycling source 421. Thus, the recycling source 421 does not operate during the user's cleaning operation.

[0121] When the user finishes cleaning and inserts the base tube 121 of the vacuum cleaner 100 into the retaining groove 441 to install the vacuum cleaner 100 into the recycling device 400, the input terminals 265 and 266 of the vacuum cleaner 100 come into contact with the output terminals 451 and 452 of the recycling device 400. In this state, the power output from the converter 454 is input to the input terminals 265 and 266 via the power supply paths 457 and 458 and the output terminals 451 and 452. Furthermore, the power input to the input terminals 265 and 266 is supplied to the battery 114 via power lines 267 and 268. As a result, the battery 114 is charged.

[0122] At this time, the contact detection circuit 456 detects the current flowing in the power supply path 458 and outputs a drive command to the drive circuit 455. The drive circuit 455 drives the recycling source 421 according to the drive command for a specified period. If the period ends, the recycling source 421 stops.

[0123] When the vacuum cleaner 100 is installed in the recycling device 400, the input terminals 265, 266 and the output terminals 451, 452 are arranged vertically. Therefore, the weight of the vacuum cleaner 100 strongly presses the input terminals 265, 266 into contact with the output terminals 451, 452. Thus, even if the frame 420 and support cylinder 430 vibrate while the recycling source 421 is operating, it is easy to maintain the contact between the input terminals 265, 266 and the output terminals 451, 452. Therefore, it is difficult for vibrations caused by the operation of the recycling source 421 to interrupt the charging of the battery 114.

[0124] In the cleaning appliance assembly 500 of the second embodiment, the input terminals 265, 266 and the output terminals 451, 452 are configured to be press-fitted together in the vertical direction. Alternatively, the input terminals 265, 266 and the output terminals 451, 452 can be configured to interlock in the vertical direction. For example, the input terminals 265, 266 may have terminal plates protruding downwards. In this case, the output terminals 451, 452 may have downwardly recessed holes to allow the terminal plates to be inserted. Conversely, the output terminals 451, 452 may have terminal plates protruding upwards, and the input terminals 265, 266 may have upwardly recessed holes.

[0125] <Third Implementation>

[0126] In the second embodiment, the recycling source 421 of the recycling device 400 automatically operates when the vacuum cleaner 100 is installed in the recycling device 400. In this case, the recycling source 421 operates even at times that the user does not want (e.g., late at night). To eliminate this problem, the recycling device 400 can be configured to keep the recycling source 421 in a stopped state according to the user's intention.

[0127] like Figure 21 As shown, a movable space 461 extending downward from the step portion 435 is formed at the upper end of the outer cylinder 432 of the recycling device 400. The movable space 461 is open not only at the step portion 435 but also on the outer peripheral surface of the outer cylinder 432.

[0128] The movable space 461 is provided to allow for vertical displacement of the release unit 436. Figure 21 The release part 436 shown protrudes upward from the step part 435 through the opening of the movable space 461 on the step part 435. In this state, the release part 436 can press the locking operation part 222 of the engaging claw part 219 upward to unlock the locking part 223 of the engaging claw part 219.

[0129] The vertical length of the movable space 461 is set such that the release part 436 can move from... Figure 21 The position shown is shifted downwards to Figure 22 The position shown. If the release part 436 is displaced to... Figure 22 At the position shown, the protrusion of the release part 436 from the step part 435 decreases, and the release part 436 does not contact the locking operation part 222. Furthermore, when the release part 436 is in... Figure 21 When in the position shown, the lower end of the release part 436 is at approximately the same height as the upper end of the opening of the movable space 461 on the outer peripheral surface of the outer cylinder 432.

[0130] A work selection section 462, operated by the user, is provided at the lower end of the release section 436 to select whether the recycling source 421 is to be activated. The work selection section 462 is in a generally horizontal position and protrudes from the opening of the movable space 461 on the outer peripheral surface of the outer cylinder 432. The work selection section 462 and the release section 436 are integrally formed, and the work selection section 462 and the release section 436 constitute a generally L-shaped operating piece 463. By pinching the distal end of the work selection section 462 protruding from the opening of the movable space 461 on the outer peripheral surface of the outer cylinder 432, the user can move the release section 436. Figure 21 The positions shown and Figure 22 The displacement between the positions shown.

[0131] Below the operating piece 463, a position detection unit 464 is provided to detect the position of the operating piece 463. The position detection unit 464 may, for example, be a reflective optical sensor. In this case, when the operating piece 463 is in a certain position... Figure 22 When in the position shown, it is in contact with the operating piece 463. Figure 21 Compared to the position shown, the optical sensor can receive stronger reflected light. This optical sensor is configured to output different signals depending on the intensity of the received reflected light.

[0132] like Figure 23 As shown, the position detection unit 464 is connected to the drive circuit 455 of the control circuit 453. (As indicated...) Figure 24 As shown, the drive circuit 455 drives or does not drive the recovery source 421 according to the signal from the position detection unit 464.

[0133] During cleaning operations using the vacuum cleaner 100, since the vacuum cleaner 100 is detached from the recycling device 400, the input terminals 265 and 266 are not in contact with the output terminals 451 and 452. Therefore, the contact detection circuit 456 does not detect the current flowing in the power supply path 458 and does not output a drive command. The drive circuit 455 does not receive a drive command from the contact detection circuit 456 (step S110: "No"), and therefore does not drive the recycling source 421, maintaining the stopped state of the recycling source 421 (step S120).

[0134] When the user finishes cleaning and connects the vacuum cleaner 100 to the recycling device 400, the input terminals 265 and 266 contact the output terminals 451 and 452. At this time, power is supplied from the converter 454 to the battery 114, and the battery 114 is charged. As a result of the power supply from the converter 454 to the battery 114, current flows to the power supply path 458, and the contact detection circuit 456 detects this current. In this case, the contact detection circuit 456 outputs a drive command.

[0135] When the drive circuit 455 receives a drive command from the contact detection circuit 456 (step S110: "Yes"), it performs the following determination process based on the signal from the position detection unit 464 (step S130).

[0136] When the user expects to recover dust from the dust storage container 200, the user configures the operating plate 463 to... Figure 21The position shown. In this case, the release part 436 protrudes significantly from the step part 435. Therefore, when the release part 436 is inserted into the receiving recess 216, it can be pressed upwards while contacting the locking operation part 222 of the engaging claw part 219. As a result, the engaging claw part 219 tilts away from the outer edge of the bottom 212 as the locking part 223 moves away, and the engagement between the locking part 223 and the bottom 212 is released. At this moment, the bottom 212 is subjected to force by the force application part 214 (see reference). Figure 3 The dust outlet 217 is sealed based on the bottom 212 by applying a force to achieve a closed posture. Therefore, dust discharge from the dust storage container 200 has not yet begun.

[0137] This indicates that the operating plate 463 is in the position of Figure 21 The position information is transmitted to the drive circuit 455 via a signal from the position detection unit 464 (step S130: "Yes"). In this case, the drive circuit 455 begins to regenerate the drive of the source 421, and the source 421 generates suction power during a specified period (step S140).

[0138] The suction force of the recovery source 421 acts on the bottom 212 through the recovery section 422, the connecting cylinder 424, and the support cylinder 430. This suction force resists the force-applying section 214, causing the bottom 212 to tilt downwards. As a result, the dust discharge port 217 is opened, and dust falls from the dust storage container 200 through the dust discharge port 217. The dust falling from the dust storage container 200 passes sequentially through the support cylinder 430 and the connecting cylinder 424 and flows into the recovery section 422.

[0139] If the user does not want the operating noise from the recycling source 421 to occur, the user can move the operating plate 463 to the desired position by pushing down the operating selection unit 462 with their fingertip. Figure 22 The operating plate 463 protrudes from the outer peripheral surface of the support cylinder 430 at its upper end, and is positioned relatively high within the recovery device 400. Therefore, the user can operate the work selection unit 462 without having to bend over significantly.

[0140] When the operating plate 463 is in Figure 22 When the position shown is such that the release portion 436 of the operating plate 463 is positioned downwards and away from the gap relative to the locking operating portion 222, and is not in contact with the locking operating portion 222. Therefore, the locking portion 223 is in a locked state, and the bottom 212 is engaged with the locking portion 223 in a closed posture that closes the dust outlet 217.

[0141] This indicates that the operating plate 463 is in the position of Figure 22The position information shown is transmitted to the drive circuit 455 via a signal from the position detection unit 464 (step S130: "No"). In this case, the drive circuit 455 does not drive the recycling source 421 and maintains the stopped state of the recycling source 421 (step S120).

[0142] In the third embodiment, the operation selection unit 462, which is operated to determine whether to activate the recycling source 421, and the release unit 436 are integrated. Therefore, the state of the locking unit 223 (i.e., the locked state and the unlocked state) that is activated based on the release unit 436 is related to the operation or non-operation of the recycling source 421 as follows.

[0143] That is, when the locking part 223 is in the locked state, the recovery source 421 does not work. Therefore, the recovery source 421 is prevented from working in a state where it is unable to recover dust from the dust storage container 200. On the other hand, when the locking part 223 is in the unlocked state, the recovery source 421 works, and therefore, dust is recovered from the dust storage container 200 to the recovery part 422.

[0144] Furthermore, as described in the first embodiment, even without the locking part 223 (engaging claw part 219), retrieval from the dust storage container 200 to the recycling part 422 is possible. However, if the dust in the dust storage container 200 is heavy, since the bottom 212 is not locked by the locking part 223, it may tilt downwards due to the weight of the dust in the dust storage container 200. Moreover, the dust falls due to gravity and accumulates at the connection portion 425 between the inner cylinder 433 of the support cylinder 430 and the connecting cylinder 424 (see reference). Figure 11 If too much dust accumulates in the connection part 425, it may cause a blockage. If the blockage cannot be eliminated even by operating the recycling source 421, the user will need to disassemble the recycling device 400 to remove the dust from the connection part 425.

[0145] Furthermore, without the locking part 223, the following problem arises: The bottom 212 tilts downwards due to the weight of the dust within the dust container 200. After some dust falls as described above, the amount of dust in the dust container 200 decreases. In this case, the downward force from the dust within the dust container 200 on the bottom 212 decreases. Since the bottom 212 is closed due to the force applied by the force-applying part 214, it gradually returns to its closed position as the downward force from the dust within the dust container 200 on the bottom 212 decreases. At this time, if dust falling from the dust container 200 is located between the bottom 212 and the lower end of the peripheral wall 211 of the dust container 200, the dust will be trapped between the bottom 212 and the peripheral wall 211. With dust held between the bottom 212 and the peripheral wall 211, if the user begins cleaning, the dust outlet 217 of the dust container 200 may not be completely sealed, potentially causing dust to leak out of the dust container 200.

[0146] On the other hand, in the third embodiment, when the locking part 223 is in the unlocked state, since the recycling source 421 is working, the dust falling from the dust storage container 200 passes through the connection portion 425 between the inner cylinder 433 of the support cylinder 430 and the connecting cylinder 424 based on the suction force of the recycling source 421. Therefore, dust blockage in the connection portion 425 is suppressed.

[0147] Furthermore, to ensure that the recycling source 421 operates for a sufficient duration to extract dust from the dust storage container 200, the problem of dust being trapped between the bottom 212 and the lower end of the peripheral wall 211 of the dust storage container 200 can be eliminated by configuring a drive circuit 455 that drives the recycling source 421. That is, the bottom 212 can remain open even when dust remains in the dust storage container 200, thanks to the suction force of the recycling source 421. Moreover, if the recycling source 421 stops, the bottom 212 becomes closed due to the force applied by the force-applying part 214. At this time, the dust has been extracted from the dust storage container 200 by the suction force of the recycling source 421, and the dust storage container 200 is essentially empty. Therefore, there is no dust trapped between the bottom 212 and the lower end of the peripheral wall 211 of the dust storage container 200.

[0148] Figure 21 and Figure 22 The work selection section 462 shown protrudes from the opening of the movable space 461 on the outer peripheral surface of the outer cylinder 432. Alternatively, the work selection section 462 can be recessed into the movable space 461. In this case, accidental contact between the user and the work selection section 462 is prevented. As a result, misoperation of the work selection section 462 can be avoided.

[0149] Figure 21The work selection unit 462 and the release unit 436 shown are integrated. As an alternative, such as... Figure 25 As shown, the work selection unit 462 can be formed separately from the release unit 436. Figure 25 In this design, the release part 436 is supported by a helical spring 471 disposed on the lower side of the release part 436. On the lower side of the helical spring 471 are provided an electromagnetic switch 472 configured to generate a magnetic attraction force, and a power supply circuit 473 configured to supply power to the electromagnetic switch 472. The release part 436 is formed of a magnetic material so that it can be attracted by the magnetic attraction force of the electromagnetic switch 472.

[0150] Figure 25 The operation selection section 462 shown is a button. When the user presses the operation selection section 462, the power supply circuit 473 is closed. In this state, the power supply circuit 473 supplies power to the electromagnetic switch 472, which generates a magnetic attraction force. Based on this attraction force, the release section 436 can be displaced downward while compressing the helical spring 471. In this state, the release section 436 is not in contact with the locking operation section 222.

[0151] If the user presses the operation selection unit 462 again, the power supply circuit 473 is disconnected. In this state, the power supply to the electromagnetic switch 472 stops, and the magnetic force of the electromagnetic switch 472 disappears. In this case, the coil spring 471 returns to its original position and extends upward to push the release part 436. In this state, the release part 436 can contact the locking operation part 222.

[0152] like Figure 26 As shown, the power supply circuit 473 is electrically connected to the drive circuit 455. The drive circuit 455 is configured to detect whether the power supply circuit 473 is closed, for example, based on the presence or absence of current flowing in the power supply circuit 473. Furthermore, the drive circuit 455 is configured to maintain the stopped state of the recycling source 421 when the power supply circuit 473 is open. On the other hand, when a drive command is output from the contact detection circuit 456 and the drive circuit 455 is closed, the drive circuit 455 activates the recycling source 421.

[0153] <Fourth Implementation>

[0154] If the speed of the swirling flow within the dust collection container 200 increases, the centrifugal force of the swirling flow becomes stronger. If the centrifugal force of the swirling flow becomes stronger, the dust contained within the swirling flow will flow away from the filter section 230 located in the center of the dust collection container 200, thus inhibiting clogging of the pores of the filter section 230. To increase the speed of the swirling flow, such as... Figure 27 As shown, the dust storage container 200 may have: a speed-increasing plate 235, which is positioned above the partition plate 233 away from the gap.

[0155] The speed-increasing plate 235 is installed in the filter section 230 with an incline that slopes downwards in the flow direction of the swirling flow. As a result, a speed-increasing channel 236 that gradually narrows in the flow direction of the swirling flow is formed between the speed-increasing plate 235 and the partition plate 233.

[0156] An acceleration channel 236 is formed in the upstream space 271, through which air flows into the acceleration channel 236 after passing through the inlet 239. Within the acceleration channel 236, the velocity of the swirling flow gradually increases, resulting in a high-speed swirling flow exiting the channel 236. Consequently, a strong centrifugal force acts on the dust contained within the swirling flow on the downstream side of the acceleration channel 236. Therefore, the dust flows radially away from the filter section 230, making it difficult for it to clog the pores of the filter section 230.

[0157] The speed-increasing flow channel 236 has the positive effect of suppressing clogging of the filter section 230 during cleaning operations. On the other hand, it has the negative effect of increasing the flow potential of the swirling flow towards the swing connection 213 during transport from the dust storage container 200 to the recovery device 400. However, if the dust storage container 200 is equipped with... Figure 14 The flow change section 225 shown can change the direction of the swirling flow that is accelerated by the speed-up flow channel 236. Therefore, even with the speed-up flow channel 236 provided, it is possible to prevent dust from being trapped in the gap 224 between the bottom 212 and the lower end of the peripheral wall 211.

[0158] In the first to fourth embodiments, the flow-changing section 225 protrudes from the inner peripheral surface of the peripheral wall section 211. Alternatively, when conveying dust from the dust storage container 200 to the recycling device 400, the flow-changing section 225 can protrude from other parts as long as the direction of the swirling flow within the dust storage container 200 can be changed. For example, the flow-changing section 225 can be configured to protrude from the bottom 212 and enter the annular space 232 via the dust discharge port 217.

[0159] In the first to fourth embodiments, the flow-changing section 225 deflects the swirling flow within the dust storage container 200 inward. Alternatively, the flow-changing section 225 may be configured to deflect the swirling flow within the dust storage container 200 upward or downward to prevent dust contained in the swirling flow from being trapped in the gap 224 between the bottom 212 and the lower end of the peripheral wall portion 211.

[0160] In embodiments 1 to 4, the user attaches the vacuum cleaner 100 to the recycling device 400. However, the user may also attach the dust collection container 200 removed from the vacuum cleaner 100 to the recycling device 400.

[0161] In embodiments 1 to 4, the vacuum cleaner 100 equipped with the dust collection container 200 is a stick type. Alternatively, the dust collection container 200 can be mounted on a self-propelled vacuum cleaner (so-called a robotic vacuum cleaner), a canister vacuum cleaner, or a portable vacuum cleaner.

[0162] (Effects, etc.)

[0163] The dust storage container 200, vacuum cleaner 100 and cleaning appliance assembly 500 described above have the following features and the following effects.

[0164] One aspect of the above-described embodiment relates to a dust storage container configured to be installed in a recycling device that contains dust, the recycling device having a recycling source that generates suction force for removing the dust. The dust storage container includes: a peripheral wall portion having an inlet for airflow; a bottom portion that closes the lower end of the peripheral wall portion; and a swing connection portion that allows the bottom to swing downwards based on the suction force of the recycling source, thus opening the opening of the peripheral wall portion, and connects the bottom to the peripheral wall portion. The peripheral wall portion is configured such that the air flowing in through the inlet portion based on the suction force of the recycling source becomes a swirling flow along the inner circumferential surface of the peripheral wall portion. The dust storage container further includes: a flow-changing portion that suppresses the situation where dust contained in the swirling flow is trapped in the gap between the bottom in the open position and the lower end of the peripheral wall portion by changing the flow direction of the airflow towards the swing connection portion in the swirling flow to another direction.

[0165] In the above configuration, the user installs a dust-containing container onto the recycling device, and the dust inside the container is sucked out using the suction power of the recycling device's recycling source. Specifically, when the bottom of the dust-containing container swings downwards to an open position based on the suction power of the recycling source, the opening at the lower end of the peripheral wall is opened. At this time, air flows into the dust-containing container from the inlet based on the suction power of the recycling source. This air flows along the inner circumferential surface of the peripheral wall, creating a swirling flow.

[0166] When the bottom of the dust collection container swings downwards to an open position, a gap is formed between the bottom and the lower end of the peripheral wall, narrowing as it moves towards the swing connection. If no flow change section is provided, the swirling airflow would flow towards this gap, and the dust contained within it would become trapped. It is foreseeable that such dust cannot be sucked out by the suction power of the recovery source. To avoid this, the above configuration includes a flow change section to alter the direction of the airflow heading towards the swing connection.

[0167] In the above configuration, the flow change section is configured to deflect the airflow in the swirling flow that is heading toward the swing connection section toward the inside of the dust storage container, so as to promote the flow of the swirling flow toward the gap between the bottom and the lower end of the peripheral wall section in the open position.

[0168] In the above configuration, the airflow destined for the swing connection in the swirling flow is deflected inward by the flow change section. As a result, the swirling flow flows inside the gap between the bottom of the open position and the lower end of the peripheral wall, thus suppressing the possibility of dust being trapped in the gap.

[0169] In the above configuration, the flow change section can protrude inward from the inner circumferential surface of the peripheral wall section.

[0170] The flow-changing section can be located at the bottom, but in this case, the flow-changing section needs to protrude from the bottom in an open position to change the direction of the swirling flow along the inner circumferential surface of the peripheral wall. Such a flow-changing section would unnecessarily become large. To prevent the flow-changing section from becoming too large, in the above configuration, the flow-changing section protrudes inward from the inner circumferential surface of the peripheral wall, rather than from the bottom.

[0171] In the above configuration, the flow change section can be provided on the upstream side of the swing connection section in the flow direction of the swirling flow, and protrude inward from the inner circumference of the peripheral wall section in an inclined posture relative to the flow direction of the swirling flow.

[0172] In the above configuration, the flow change section is tilted downstream of the swirling flow direction, which reduces the amount of dust trapped in the flow change section.

[0173] In the above configuration, the dust storage container may further include: a force-applying part that applies a force to the bottom in a closed posture towards the lower end of the closed peripheral wall.

[0174] In the above configuration, the bottom is subjected to a closing force based on the force-applying part, so even when dust accumulates inside the dust storage container, it is difficult for the bottom to be pushed down by the weight of the dust. Therefore, before the user installs the dust storage container into the recycling device, the possibility of the bottom swinging downwards and causing dust inside the dust storage container to fall out is suppressed.

[0175] In the above configuration, the dust storage container may further include: a locking part that can switch between a locked state and an unlocked state. The locked state is a state in which the bottom of the opening in the closed peripheral wall is locked, and the unlocked state is a state in which the bottom is released from locking.

[0176] In the above configuration, when dust accumulates in the dust collection container, the weight of the dust itself tends to cause the bottom, which is in a closed position, to tilt downwards. However, if the bottom is locked by the locking part, the lower end of the peripheral wall can be kept closed by the bottom. Therefore, by setting the locking part to the locked state, the possibility of the bottom tilting downwards and causing dust to fall out of the dust collection container is prevented before the user installs the dust collection container into the recycling device. On the other hand, if the user sets the locking part to the unlocked state, the bottom is allowed to tilt downwards, allowing the dust to be recycled into the recycling device.

[0177] In the above configuration, the dust storage container may further include a locking operation part that is operated to switch the locking part from a locked state to an unlocked state. The dust storage container may also include a receiving recess that accommodates the locking operation part in a state where the locking operation part is submerged.

[0178] In the above configuration, the user can switch the locking unit from the locked state to the unlocked state by operating the locking operation unit. The locking operation unit is housed within the receiving recess, making accidental contact with the locking operation unit unlikely. Therefore, it prevents the locking unit from accidentally becoming unlocked.

[0179] Another aspect of the above-described embodiments relates to a vacuum cleaner comprising: a suction source that generates suction force for suctioning dust; a suction tube that forms a flow channel for dust to flow based on the suction force of the suction source; and the aforementioned dust collection container. The dust collection container is connected to the suction tube in such a way that the suction force of the suction source acts on the flow channel of the suction tube through the dust collection container when the suction source is operating, and allows dust flowing in the flow channel of the suction tube to flow into the dust collection container through an inlet.

[0180] In the above configuration, when the suction source is operating, the suction force of the suction source acts on the flow channel of the suction pipe through the dust storage container. As a result, dust flows in the flow channel of the suction pipe and flows into the dust storage container.

[0181] In the above configuration, the vacuum cleaner may further include: a filter section housed in a dust collection container in such a way as to form an annular space between itself and a peripheral wall section for allowing swirling flow, and which captures dust contained in the air while allowing air in the annular space to flow in when the suction source is operating; and an acceleration channel configured to accelerate the swirling flow.

[0182] In the above configuration, when the suction source is operating, air in the annular space formed between the filter section and the peripheral wall flows into the filter section. Dust-laden air, in an amount equivalent to the amount flowing into the filter section, flows in from the inlet. This air flows within the annular space, forming a swirling flow. Because this swirling flow is accelerated by the speed-increasing flow channel, the centrifugal force of the swirling flow increases, causing the dust contained within the swirling flow to move away from the filter section. As a result, it is difficult for the filter section's pores to become clogged.

[0183] Thus, the speed-increasing flow channel effectively suppresses clogging of the filter pores when the suction source is operating. However, when the dust storage container is installed in the recovery device, the speed-increasing flow channel may have the negative effect of enhancing the airflow heading towards the swing connection. However, because the dust storage container has a flow-changing section, even if the swirling flow is enhanced by the speed-increasing flow channel, the direction of the airflow heading towards the swing connection is changed by the flow-changing section. Therefore, the situation where dust is trapped in the gap between the bottom and the lower end of the peripheral wall in the open position is prevented.

[0184] In the above configuration, the vacuum cleaner may also include: a storage battery that stores electricity for operating the suction source.

[0185] In the above configuration, the suction source uses the electricity stored in the battery to generate suction force.

[0186] In the above configuration, the vacuum cleaner may further include: a suction nozzle configured to be mounted at the lower end of a suction tube. The suction nozzle may form an intake port for drawing in dust based on the suction force of a suction source.

[0187] In the above configuration, the user can attach the nozzle to the lower end of the suction tube according to the size of the cleaning area. For example, if the user wants to suck up dust from a spacious floor area, they can simply attach the nozzle with a suction opening wider than the suction tube to the lower end of the suction tube. Conversely, if the user wants to remove dust from a narrow space, they can simply attach the nozzle with a suction opening narrower than the suction tube to the lower end of the suction tube.

[0188] Another aspect of the above-described embodiments relates to a cleaning appliance assembly comprising: the aforementioned dust storage container; and a recovery device configured to install the dust storage container and recover dust from within the dust storage container while it is installed. The recovery device includes: a support cylinder that supports the dust storage container and has a flow channel extending in the vertical direction to allow dust falling from the dust storage container to flow; and a recovery source that generates a suction force that keeps the bottom of the dust storage container, supported by the support cylinder, in an open position, draws dust from the dust storage container, and causes the dust to fall into the support cylinder.

[0189] In the above configuration, if the recycling source operates while the dust storage container is supported by the support cylinder of the recycling device, the bottom is kept open due to the suction force of the recycling source. At this time, the support cylinder forms a flow channel extending in the vertical direction, allowing dust in the dust storage container to fall into the support cylinder. This dust is affected not only by the suction force of the recycling source but also by gravity; therefore, the required suction capacity of the recycling source will not become excessive.

[0190] Another aspect of the above-described embodiments relates to a cleaning appliance assembly comprising: the aforementioned dust collection container; and a recovery device configured to install the dust collection container and recover dust from within the dust collection container while it is installed. The recovery device includes: a support cylinder that supports the dust collection container and has a flow channel extending in the vertical direction to allow dust falling from the dust collection container to flow; and a recovery source that generates a suction force that resists the applied force, keeping the bottom of the dust collection container, supported by the support cylinder, in an open position, and drawing dust from the dust collection container and causing it to fall into the support cylinder.

[0191] In the above configuration, if the recovery source operates while the dust storage container is supported by the support cylinder of the recovery device, the bottom remains open due to the suction force of the recovery source, resisting the force applied. As a result, the dust in the dust storage container can fall into the support cylinder. At this time, the dust is affected not only by the suction force of the recovery source but also by gravity, therefore, the suction capacity required by the recovery source will not become excessive.

[0192] The cleaning appliance assembly according to another aspect of the above-described embodiments includes: the aforementioned dust collection container; and a recovery device configured to install the dust collection container and recover dust from the dust collection container while it is installed. The recovery device includes: a support cylinder that supports the dust collection container and has a flow channel extending in the vertical direction to allow dust falling from the dust collection container to flow; a release unit that unlocks the locking portion of the dust collection container supported by the support cylinder; a recovery source that generates suction force to keep the bottom of the dust collection container, supported by the support cylinder, in an open position while the locking portion is unlocked, and to draw dust from the dust collection container; and a work selection unit that can be operated to select whether the recovery source is to operate. The recovery source is configured to operate when the condition for operating the work selection unit is selected. The release unit is configured to unlock the locking portion when the condition for operating the work selection unit is selected.

[0193] In the above configuration, when the user wishes to empty the dust collection container, they simply need to operate the operation selection unit to activate the recycling source while the dust collection container is supported by the support cylinder. At this time, based on the operation of the operation selection unit, the release unit unlocks the locking unit. In this state, if the recycling source is operating, based on the suction power of the recycling source, the bottom is kept open, and dust is sucked out of the dust collection container.

[0194] On the other hand, if the user does not want the recycling source to make any operating noise, they can choose to disable the recycling source by operating the operation selection unit. In this case, the release unit does not set the locking unit to the unlocked state, so the bottom is kept in a closed position and dust will not fall into the support cylinder.

[0195] If the release unit releases the bottom lock while the recycling source is not in operation, it is foreseeable that the bottom will be pushed down by the weight of the dust in the dust collection container. In this case, it is foreseeable that although the dust falls into the support cylinder, it will become stuck in the middle of the support cylinder due to the lack of suction from the recycling source. To prevent this from happening, the release unit is configured to unlock the lock unit when the recycling source is activated by operating the operation selection unit.

[0196] The cleaning appliance assembly according to another aspect of the above-described embodiments includes: the aforementioned dust collection container; and a recovery device configured to install the dust collection container and recover dust from the dust collection container while it is installed. The recovery device includes: a support cylinder that supports the dust collection container and has a flow channel extending in the vertical direction to allow dust falling from the dust collection container to flow; a release section that unlocks the locking portion of the dust collection container supported by the support cylinder; a recovery source that generates suction force to keep the bottom of the dust collection container, supported by the support cylinder, in an open position while the locking portion is unlocked, and to draw dust from the dust collection container; and a work selection section that can be operated to select whether the recovery source is to be operated. The recovery source is configured to operate when the work selection section is selected to operate. The release section is configured to be inserted into the receiving recess and contact the locking operation section when the work selection section is selected to operate the recovery source while the dust collection container is supported by the support cylinder. The locking operation unit is configured to set the locking unit to the unlocked state by contacting the unlocking unit.

[0197] In the above configuration, when the user operates the work selection unit to activate the recycling source while the dust storage container is supported by the support cylinder, the release part is inserted into the receiving recess and contacts the locking operation part. Based on the contact between the release part and the locking operation part, the locking operation part sets the locking part to the unlocked state, allowing dust to be recycled from the dust storage container.

[0198] Another aspect of the above-described embodiments relates to a cleaning appliance assembly comprising: the aforementioned vacuum cleaner; and a recovery device configured to be able to mount the vacuum cleaner and, while the vacuum cleaner is mounted, recover dust from a dust collection container. The recovery device includes: a support cylinder that supports the dust collection container and has a flow channel extending in the vertical direction to allow dust falling from the dust collection container to flow; and a recovery source that generates a suction force that keeps the bottom of the dust collection container, supported by the support cylinder, in an open position, sucks dust from the dust collection container, and causes the dust to fall into the support cylinder.

[0199] In the above configuration, the user can attach the vacuum cleaner to the recycling device with the dust collection container supported by the support cylinder of the recycling device. In this state, when the recycling source is operating, the bottom is kept open based on the suction force of the recycling source. At this time, the support cylinder forms a flow channel extending in the vertical direction, allowing dust in the dust collection container to fall into the support cylinder. This dust is affected not only by the suction force of the recycling source but also by gravity; therefore, the suction capacity required by the recycling source does not become excessive.

[0200] In the above configuration, the recycling device may have: a tube holding part that holds the suction tube in a posture that extends along the vertical direction of the support cylinder when the dust storage container is supported by the support cylinder.

[0201] In the above configuration, with the dust storage container supported by the support cylinder, the suction pipe is held by the pipe holding part in a vertically extending position along the support cylinder. Therefore, the cleaning appliance assembly does not require a large space in the front-back and left-right directions.

[0202] In the above configuration, the support cylinder may have an axial length such that the lower end of the suction pipe is suspended in the air when the dust storage container is supported by the support cylinder.

[0203] In the above configuration, when the recycling source operates with the dust storage container supported by the support cylinder, the bottom tilts downwards due to the suction force of the recycling source, connecting the internal space of the support cylinder and the dust storage space. Therefore, the suction force of the recycling source acts on the support cylinder, the dust storage container, and the suction pipe, drawing air from the vicinity of the cleaning appliance assembly from the lower end of the suction pipe. Since the lower end of the suction pipe is suspended in the air, air can flow into the suction pipe without high resistance. Therefore, the suction capacity required by the recycling source does not become excessive.

[0204] In the above configuration, the recovery device may include: a connecting tube, which is configured to extend curvedly from the support tube; and a recovery section, which is connected to the connecting tube and stores the dust that has passed through the support tube and the connecting tube. The recovery section and the recovery source may be configured on the opposite side of the suction tube held by the tube holding section relative to the support tube.

[0205] In the above configuration, because a tube holding part is provided to hold the suction tube, the user can install the vacuum cleaner in the recovery device with the suction tube held in the same direction by the tube holding part. The weight of the suction tube may cause the support cylinder to tilt, but since the recovery part and recovery source are located on the opposite side of the suction tube, the tilting of the support cylinder is suppressed.

[0206] In the above configuration, the axial length of the support cylinder can be longer than the axial length of the connecting cylinder.

[0207] In the above configuration, the relatively long axial length of the support cylinder allows the dust collection container to be supported at a higher position. This allows for the installation of taller vacuum cleaners in the recovery unit. Furthermore, the flow of dust from the dust collection container to the connection between the support cylinder and the connecting cylinder is aided by the force of gravity acting on the dust. Therefore, even with the long axial length of the support cylinder, dust blockage within it is unlikely. Because the connecting cylinder has a relatively short axial length, dust reaching the connection between the support cylinder and the connecting cylinder can be subjected to a relatively high suction force. Therefore, dust can flow into the recovery section without remaining at the connection between the support cylinder and the connecting cylinder.

[0208] In the above configuration, the suction source can be arranged on the upper side of the dust storage container in such a way that the dust storage container is arranged axially with the dust storage container in the support cylinder while the dust storage container is supported by the support cylinder.

[0209] In the above configuration, the suction source is positioned above the dust storage container, and when the dust storage container is supported by the support cylinder, the suction source and the dust storage container are aligned axially along the support cylinder. Therefore, the weight of the suction source is unlikely to cause the support cylinder to tilt.

[0210] Another aspect of the above-described embodiments relates to a cleaning appliance assembly comprising: the aforementioned vacuum cleaner; and a recovery device configured to be able to mount the vacuum cleaner and, when the vacuum cleaner is mounted, recover dust from a dust collection container. The recovery device includes: a support cylinder that supports the dust collection container and has a flow channel extending in the vertical direction to allow dust falling from the dust collection container to flow; and a recovery source that generates a suction force that keeps the bottom of the dust collection container, supported by the support cylinder, in an open position, sucks dust from the dust collection container, and causes the dust to fall into the support cylinder. A battery is disposed on the upper side of the dust collection container such that, when the dust collection container is supported by the support cylinder, it is arranged axially along the support cylinder.

[0211] In the above configuration, the battery is positioned above the dust collection container, and when the dust collection container is supported by the support cylinder, the battery and the dust collection container are aligned axially along the support cylinder. Therefore, the weight of the battery is unlikely to cause the support cylinder to tilt.

[0212] In the above configuration, the recycling device may have an output terminal for outputting power. The vacuum cleaner may have: an input terminal that receives power by contacting the output terminal when the dust collection container is supported by the support cylinder and the vacuum cleaner is installed in the recycling device; and a power line that forms a power transmission path from the input terminal to the battery. The output terminal and the input terminal may be engaged or pressed together along the axial direction of the support cylinder.

[0213] In the above configuration, power output from the output terminal is supplied to the battery via the input terminal and power lines. Based on this power, the battery can be charged. The output terminal and input terminal are engaged or pressed together along the axial direction of the support cylinder. Therefore, the weight of the battery itself can maintain the engagement or contact state of the output terminal and input terminal.

[0214] Another aspect of the above-described embodiments relates to a cleaning appliance assembly that may include: the aforementioned vacuum cleaner; and a recovery device configured to be able to mount the vacuum cleaner and, when the vacuum cleaner is mounted, recover dust from a dust collection container. The recovery device may include: a support cylinder that supports the dust collection container and has a flow channel extending in the vertical direction to allow dust falling from the dust collection container to flow; a recovery source that generates a suction force that keeps the bottom of the dust collection container, supported by the support cylinder, in an open position, sucks dust from the dust collection container, and causes the dust to fall into the support cylinder; and a tube holding portion that holds the suction tube in a vertically extending position along the support cylinder when the dust collection container is supported by the support cylinder. The support cylinder may have an axial length such that, when the dust collection container is supported by the support cylinder, the suction inlet of the nozzle is open in the air.

[0215] In the above configuration, if the recycling source operates with the dust collection container supported by the support cylinder, the suction force of the recycling source acts on the suction inlet of the nozzle through the support cylinder, the dust collection container, and the suction pipe, and draws air from the vicinity of the cleaning appliance assembly from the suction inlet. Since the suction inlet is open in the air, air can flow into the nozzle without high resistance. Therefore, the suction capacity required by the recycling source will not become excessive.
