Cleaner and cleaning device assembly

Abstract

The invention provides a vacuum cleaner and a cleaning appliance set. The vacuum cleaner comprises: a housing having a driving chamber in which a suction source is accommodated and a dust storage chamber into which dust flows; and a filter that captures dust. A cushion space for preventing the filter from coming into contact with the suction source is formed between the filter and the suction source. The housing is provided with: a dust discharge port that communicates with the dust storage chamber so as to allow dust to be discharged from the dust storage chamber; and an inflow port for allowing air for promoting discharge of dust through the dust discharge port to flow in from the outside of the housing in a state where a dust suction force for sucking dust from the dust storage chamber acts on the dust discharge port, and a cover for opening and closing the dust discharge port is attached to the housing. The inflow port is formed in the cushion space or at a position communicating with the dust storage chamber so that air flowing in through the inflow port does not collide with the suction source. Therefore, the force of air for discharging dust from the dust storage chamber of the dust collector can be improved.

Description

Technical Field

[0001] This disclosure relates to a vacuum cleaner having a suction source that generates suction force for vacuuming dust, and a cleaning appliance assembly having the vacuum cleaner. Background Technology

[0002] Patent document 1 discloses Figure 22 The cleaning appliance assembly 300 shown includes: a stick vacuum cleaner 310 configured to suck up dust from a floor surface; and a dust collection device 320 for collecting dust from the vacuum cleaner 310.

[0003] The vacuum cleaner 310 has: a generally cylindrical housing 311 extending vertically; a grip portion 312 extending upward from the upper end of the housing 311; and a suction nozzle 313 disposed on the lower side of the housing 311. A suction tube 314 forming a flow path for dust flow is housed in the lower part of the housing 311, and the lower end of the suction tube 314 is connected to the suction nozzle 313.

[0004] The internal space of the housing 311 on the upper side of the suction tube 314 is as follows: Figure 23 As shown, the system is divided into: a dust collection chamber 315; a filter chamber 316 disposed above the dust collection chamber 315; and a drive chamber 317 disposed above the filter chamber 316. The dust collection chamber 315 is a space for storing dust that has passed through the suction nozzle 313 and the suction pipe 314. The filter chamber 316 is equipped with: a primary filter 318 configured to centrifuge the dust contained in the air; and a secondary filter 319 for removing dust that was not completely removed by the primary filter 318.

[0005] A suction source 341 configured to generate an upward suction force is disposed in the drive chamber 317. When the user uses the vacuum cleaner 100 to perform cleaning operations, dust on the floor surface is drawn into the dust collection chamber 315 along with air through the nozzle 313 and suction tube 314 by the suction force of the suction source 341. Then, the air and dust flow into the filter chamber 316, where the dust is separated from the air by the primary filter 318 and the secondary filter 319. Therefore, the air after dust removal flows into the drive chamber 317. After the suction source 341 in the drive chamber 317 stops, the dust falls from the filter chamber 316 into the dust collection chamber 315.

[0006] In order to discharge the dust accumulated in the dust storage chamber 315, on the rear surface of the housing 311, such as Figure 23As shown, a dust discharge port 342 and an inlet port 343 are formed. The dust discharge port 342 is positioned at a height communicating with the dust storage chamber 315, through which dust is discharged from the dust storage chamber 315. The inlet port 343 is formed at a height communicating with the drive chamber 317, and when dust is discharged from the dust storage chamber 315, air outside the housing 311 flows into the housing 311 through the inlet port 343. This air passes sequentially through the drive chamber 317 and the filter chamber 316, pushing the dust in the dust storage chamber 315 out through the dust discharge port 342.

[0007] Recycling device 320, etc. Figure 22 The device shown includes: a mounting portion 321 for mounting a suction nozzle 313; and a generally rectangular box-shaped housing 322 erected upright on the rear side of the mounting portion 321. The front wall of the housing 322 of the recycling device 320 is as follows... Figure 24 As shown, a groove 323 is provided extending in the vertical direction. The groove 323 is embedded in the rear part of the housing 311 of the vacuum cleaner 310, in which the nozzle 313 is placed in the mounting part 321.

[0008] Within the recess 323, the dust inlet 324 and the outlet 325 are open. The dust inlet 324 is formed at a height position facing the dust outlet 342 of the vacuum cleaner 310, on which the nozzle 313 is mounted in the mounting portion 321. The outlet 325 is formed at a height position facing the inlet 343 of the vacuum cleaner 310, on which the nozzle 313 is mounted in the mounting portion 321. When the vacuum cleaner 310 is connected to the recycling device 320, the internal space of the housing 322 of the recycling device 320 communicates with the drive chamber 317 through the outlet 325 and the inlet 343.

[0009] like Figure 23 As shown, the housing 322 includes a dust collection section 326 for collecting dust collected from the vacuum cleaner 310, and a collection pipe 327 that forms a flow path for dust flowing from the dust inlet 324 to the dust collection section 326. A suction source 328 for generating suction force to suck up dust from the vacuum cleaner 310 is disposed on the lower side of the dust collection section 326.

[0010] The suction source 328 is configured to draw air out of the dust collection chamber 326 downwards. If air is drawn out of the dust collection chamber 326 by the suction source 328, the suction force of the suction source 328 acts on the interior of the vacuum cleaner 310 through the dust collection chamber 326, the recovery pipe 327, and the dust inlet 324. Inside the vacuum cleaner 310, the suction force of the suction source 328 acts on the dust storage chamber 315, the filter chamber 316, the drive chamber 317, and the inlet 343. Since the outlet 325 is formed in the housing 322 of the recovery device 320 facing the inlet 343, air in the housing 322 of the recovery device 320 flows into the drive chamber 317 through the outlet 325 and the inlet 343. This air then flows into the dust storage chamber 315 through the filter chamber 316, and the dust in the dust storage chamber 315 is pushed towards the recovery pipe 327 through the dust outlet 342. The dust flows along with the air through the recovery pipe 327 and is collected into the dust containment section 326.

[0011] In the cleaning appliance assembly 300, the inlet 343 of the vacuum cleaner 310 is connected to the drive chamber 317. Therefore, air flowing in from the inlet 343 collides with the suction source 341 within the drive chamber 317. As a result, the suction source 341 acts as a resistance unit, reducing the amount of air flowing in from the inlet 343. Thus, the amount of air flowing in through the inlet 343 may be reduced due to the suction source 341. Corresponding to the reduction in airflow caused by the suction source 341, the force pushing dust out of the dust collection chamber 315 may be weakened.

[0045] Hereinafter, the first to third embodiments of the cleaning appliance assembly will be described in detail with reference to the accompanying drawings. However, in order to facilitate understanding by those skilled in the art, detailed descriptions of matters already well known or repeated descriptions of substantially the same configurations are sometimes 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.

[0046] (First Embodiment)

[0047] Figure 1The cleaning appliance assembly 101 shown includes: a stick vacuum cleaner 100 for cleaning operations; and a dust collection device 200 for collecting dust from the vacuum cleaner 100. After finishing the cleaning operation, the user, such as... Figure 1 As shown, a vacuum cleaner 100 can be mounted on a collection device 200. The collection device 200 is configured to suck up dust from the vacuum cleaner 100 in this state.

[0048] (The overall structure of a vacuum cleaner)

[0049] like Figure 2 As shown, the vacuum cleaner 100 includes: a generally cylindrical first housing 110 extending in a vertical direction; a suction nozzle 130 disposed on the lower side of the first housing 110; and a generally cylindrical grip portion 140 extending upward from the upper end 112 of the first housing 110. The grip portion 140 is thinner than the first housing 110 so that the user can hold it.

[0050] The nozzle 130 has: a generally rectangular box-shaped nozzle housing 131 that is elongated in the left-right direction; and a support 132 that protrudes rearward from the rear end of the nozzle housing 131. Figure 1 As shown, an auxiliary roller 133 for assisting the movement of the suction nozzle 130 on the floor surface is rotatably mounted on the bracket 132. The lower part of the auxiliary roller 133 protrudes from the lower surface of the bracket 132. The auxiliary roller 133 assists the movement of the suction nozzle 130 by rolling on the floor surface.

[0051] On the front part of the nozzle housing 131, as shown Figure 1 A suction space 134 is formed as shown. The suction space 134 opens downwards to allow dust on the floor surface to flow into it. A rotating brush 135 is disposed within the suction space 134, with its lower part protruding downwards from the lower surface of the nozzle housing 131. As the rotating brush 135 rotates within the suction space 134, the floor surface and the rotating brush 135 rub against each other, and the dust on the floor surface is swept away.

[0052] On the rear side of the nozzle housing 131, as shown Figure 1 The lower end of a suction tube 136, which forms a flow path for dust flow, is connected to the shown. Most of the suction tube 136 is housed in the lower part of the first housing 110.

[0053] At the upper end of the suction tube 136, as shown Figure 1 A check valve 137 is installed as shown. Figure 1 The check valve 137 shown closes the opening at the upper end of the suction tube 136. If an upward external force is applied to the check valve 137, the check valve 137 can rotate upward about its rear end.

[0054] Within the first housing 110, at a position spaced apart upwards from the check valve 137, such as Figure 1 The diagram shows a filter 141, a suction source 142, and a battery 143. The battery 143 stores power for the suction source 142. The suction source 142 is configured to use the power from the battery 143 to generate an upward suction force for suctioning dust from the floor surface. For example, the suction source 142 may include a motor that generates a rotational force, and rotating blades driven by the motor to generate an upward airflow.

[0055] Based on the suction force of the suction source 142, the check valve 137 rotates upward. In this state, dust on the floor surface passes through the suction nozzle 130 and the suction tube 136 in sequence along with air. In the following description, the part of the first housing 110 that houses the suction source 142 and the battery 143 is referred to as the "drive chamber 144".

[0056] The filter 141 is fixed within the first housing 110 at a position spaced downward from the suction source 142. In the following description, the space between the filter 141 and the suction source 142 is referred to as the "buffer space 145". This buffer space 145 is provided to prevent the suction source 142 from contacting the filter 141.

[0057] The filter 141 is configured to allow air to pass through while simultaneously capturing dust contained in the air. Therefore, dust drawn up by the suction force of the suction source 142 and passing through the suction pipe 136 is retained in the space below the filter 141. In the following description, the space below the filter 141 and above the check valve 137 will be referred to as the "dust storage chamber 146". The dust captured by the filter 141 accumulates in the dust storage chamber 146. Furthermore, the filter 141 is formed of a resin sheet with numerous vent holes.

[0058] In order to remove the dust accumulated in the dust storage chamber 146, such as Figure 2 As shown, a dust discharge port 147 is formed on the front surface of the first housing 110 in a manner communicating with the dust storage chamber 146. In addition, a cover 148 is installed on the first housing 110 to open or close the dust discharge port 147. Figure 2 The cover 148 shown is in the open position with the dust vent 147 open. The user can close the dust vent 147 by rotating the cover 148 upward about the connection between the cover 148 and the first housing 110.

[0059] like Figure 2As shown, an inlet 149 is formed on the front surface of the first housing 110 above the dust outlet 147 to allow air from outside the first housing 110 to flow into it. The inlet 149 can be formed at a position relative to the suction source 142 on the side of the dust storage chamber 146 and relative to the dust outlet 147 on the side of the drive chamber 144. In this embodiment, as shown... Figure 1 As shown, the inlet 149 opens below the suction source 142 and above the filter 141, and communicates with the buffer space 145. When the suction force used to remove dust from the dust collection chamber 146 acts on the exhaust port 147, air outside the first housing 110 flows into the buffer space 145 through the inlet 149. Subsequently, this air passes sequentially through the filter 141 and the dust collection chamber 146 and is discharged from the exhaust port 147. Utilizing this airflow, dust in the dust collection chamber 146 is discharged through the exhaust port 147.

[0060] A cover 138 for opening or closing the inlet 149 is installed on the first housing 110. Figure 2 The cover 138 shown is in the open position with the inlet 149 open, and the right end of the cover 138 is connected to the first housing 110. The user can close the inlet 149 by rotating the cover 138 toward the first housing 110 with the right end of the cover 138 as the axis.

[0061] (Overall structure of the recycling device)

[0062] Figure 1 The recovery device 200 shown is configured to use suction force to act on the dust outlet 147 of the vacuum cleaner 100 connected to the recovery device 200 to suck out dust from the dust collection chamber 146, thereby recovering the dust. Specifically, the recovery device 200 includes: a base plate 211 on which the vacuum cleaner 100 is mounted; and a generally rectangular box-shaped second housing 212 mounted on the base plate 211. The height of the recovery device 200 (i.e., the height of the upper end of the second housing 212) is lower than the position of the inlet 149 of the vacuum cleaner 100. Therefore, even if the vacuum cleaner 100... Figure 1 As shown, the inlet 149 is installed in the recycling device 200 and will not be blocked by the recycling device 200. In addition, the user can operate the cover 138 to open the inlet 149 without being obstructed by the recycling device 200.

[0063] like Figure 3 and Figure 4As shown, a positioning portion 214 is formed on the rear wall 213 of the second housing 212. This positioning portion 214 is formed as a groove extending in the vertical direction, complementing the front portion of the first housing 110 of the vacuum cleaner 100. The first housing 110 is positioned on the base plate 211 by being inserted into the positioning portion 214. Preferably, the positioning portion 214 is recessed deeper relative to the rear wall 213 to the extent that the front portion of the first housing 110 is completely contained. This improves the positioning accuracy of the first housing 110 in the left-right direction.

[0064] In order to allow dust sucked from the dust collection chamber 146 of the vacuum cleaner 100 to flow into the recycling device 200, such as Figure 4 As shown, a dust inlet 215 is formed in the positioning part 214. (As indicated...) Figure 1 As shown, the height of the dust inlet 215 is set such that the dust inlet 215 faces the dust outlet 147 of the vacuum cleaner 100 mounted on the base plate 211.

[0065] In order to store the dust sucked out of the dust collection chamber 146 of the vacuum cleaner 100 in the second housing 212 of the recycling device 200, such as Figure 1 As shown, a dust collection section 216 is disposed within the second housing 212. Furthermore, to form a flow path for dust sucked from the dust chamber 146 of the vacuum cleaner 100 to flow toward the dust collection section 216, a recovery pipe 217 is provided extending rearward from the dust collection section 216, with its rear end fixed to the dust inlet 215. Therefore, dust sucked from the dust chamber 146 of the vacuum cleaner 100 can flow into the dust collection section 216 through the recovery pipe 217.

[0066] like Figure 3 As shown, a filter 218 is fixed at the bottom of the dust collection section 216, which on the one hand retains dust inside the dust collection section 216, and on the other hand allows air to flow out from the dust collection section 216. Figure 1 As shown, a suction source 219 that generates downward suction force is disposed on the lower side of the dust collection section 216. The suction source 219 is configured to receive power via a power cable 229 connected to an external power source to generate suction force. Based on the suction force of the suction source 219, the air inside the dust collection section 216 is drawn out downward through the filter 218. For example, the suction source 219 may include a motor that generates rotational force; and rotating blades driven by the motor to rotate, thereby generating downward airflow.

[0067] (Explanation of the operation of the vacuum cleaner during cleaning)

[0068] The user places the vacuum cleaner 100 on the floor and closes the dust outlet 147 and inlet 149 using the cover 148 and cover plate 138. In this state, if the suction source 142 is operating, the check valve 137 rotates upwards based on the upward suction force of the suction source 142, opening the upper end of the suction tube 136. As a result, the suction force of the suction source 142 acts on the suction space 134 of the nozzle 130. At this time, by using the cover 148 and cover plate 138 to prevent air from flowing into the dust collection chamber 146 and buffer space 145, the suction force in the suction space 134 of the nozzle 130 is reduced.

[0069] Based on the suction force acting on the suction space 134, dust on the floor surface is sucked into the suction space 134. At this time, even if the dust is attached to the floor surface, it can be swept away by the rotating brush 135 rotating inside the suction space 134.

[0070] Dust drawn into the suction space 134 flows along with air through the suction pipe 136 and into the dust storage chamber 146. The air flowing into the dust storage chamber 146 can pass through the filter 141 into the buffer space 145 and the drive chamber 144; conversely, the dust contained in this air is retained in the dust storage chamber 146 by the filter 141. As a result, dust accumulates in the dust storage chamber 146.

[0071] (Explanation of the operation of the dust recovery device)

[0072] Once the cleaning operation is complete, the user moves the cover 148 to the open position and installs the vacuum cleaner 100 onto the recycling device 200. That is, the user places the vacuum cleaner 100 on the base plate 211 of the recycling device 200 and inserts the first housing 110 of the vacuum cleaner 100 into the positioning portion 214 of the recycling device 200. When the first housing 110 is inserted into the positioning portion 214, the dust outlet 147 of the vacuum cleaner 100 faces the dust inlet 215 of the recycling device 200.

[0073] After the vacuum cleaner 100 is installed on the recycling device 200, the user moves the cover 138 of the vacuum cleaner 100, which is located higher than the recycling device 200, to the open position to open the inlet 149. In this state, if the suction source 219 of the recycling device 200 is working, the suction force of the suction source 219 acts on the inlet 149 through the dust collection section 216, the recycling pipe 217, the dust storage chamber 146, the filter 141, and the buffer space 145.

[0074] Therefore, air outside the first housing 110 of the vacuum cleaner 100 flows into the buffer space 145 through the inlet 149. This air then flows downwards and through the filter 141 into the dust collection chamber 146. At this time, dust still attached to the filter 141 after the cleaning operation can be detached from the filter 141 and fall into the dust collection chamber 146 based on the downward airflow through the filter 141. As a result, clogging of the filter 141 can be eliminated.

[0075] The air flowing into the dust storage chamber 146 pushes the dust inside the dust storage chamber 146 toward the dust discharge port 147. As a result, the dust is discharged from the dust storage chamber 146 through the dust discharge port 147. Subsequently, the dust flows into the recovery pipe 217 through the dust inlet 215 of the recovery device 200, and flows into the dust collection section 216 along with the air through the recovery pipe 217.

[0076] Figure 1 In the cleaning appliance assembly 101 shown, the inlet 149 of the vacuum cleaner 100 does not open into the drive chamber 144, but rather forms an opening in a buffer space 145 provided to prevent the filter 141 from contacting the suction source 142. Therefore, air flowing in through the inlet 149 will not collide with the suction source 142 within the drive chamber 144 and can pass through the filter 141 and the dust collection chamber 146. In this case, the flow of air flowing in through the inlet 149 is not significantly obstructed by the suction source 142, and thus, the amount of air flowing in through the inlet 149 can be increased.

[0077] As the airflow through inlet 149 increases, dust adhering to filter 141 is easily detached due to the air passing through filter 141. In other words, clogging of filter 141 is easily eliminated. Furthermore, as the airflow through inlet 149 increases, dust in dust collection chamber 146 can be discharged through exhaust port 147 under greater force from the air. Accordingly, the time required to discharge dust from dust collection chamber 146 can be shortened.

[0078] In addition, in order to improve the effect of eliminating clogging of filter 141, Figure 1In the cleaning appliance assembly 101 shown, the filter 141 is formed of a resin sheet with numerous vent holes. If the filter 141 is made of non-woven fabric, fuzzing may occur on its surface due to air passing through it. Furthermore, in the event of fuzzing, dust becomes trapped on the surface of the filter 141 by the fuzzy fibers, making it difficult to separate from the filter 141. On the other hand, if the filter 141 is made of a resin sheet, this fuzzing is less likely to occur. Therefore, compared to the case where the filter 141 is made of non-woven fabric, dust separation from the filter 141 is facilitated. Additionally, if the method of replacing the filter 141 before fuzzing occurs is adopted, a non-woven fabric filter can also be used as the filter 141.

[0079] exist Figure 1 In the cleaning appliance assembly 101 shown, a cover 138 is mounted on the vacuum cleaner 100. With the cover 138 closing the inlet 149, even when the suction source 142 is operating, the inflow of air through the inlet 149 is suppressed, thus preventing a decrease in suction force acting on the suction space 134 of the nozzle 130. However, even if air flows in through the inlet 149, as long as the suction force acting on the suction space 134 of the nozzle 130 is sufficient to pick up dust from the floor surface, the cover 138 can be omitted. In this case, the structure of the vacuum cleaner 100 can be simplified.

[0080] exist Figure 1 In the cleaning appliance assembly 101 shown, both the inlet 149 and the exhaust port 147 open forward. In this case, if the recovery device 200 is tall, the inlet 149 may be blocked by the recovery device 200. To improve this situation, the inlet 149 can also be formed to open in a direction different from the exhaust port 147. For example, the inlet 149 can open on the rear, right, or left surface of the first housing 110. In this case, the recovery device 200, as... Figure 5 The height can also be increased. In this case, the volume of the second housing 212 becomes larger, thus allowing the dust containment section 216 to also be increased in size.

[0081] Figure 1 The cleaning appliance assembly 101 shown uses a single filter 141 to prevent dust from flowing into the drive chamber 144. To further prevent dust from flowing into the drive chamber 144, the cleaning appliance assembly 101 can also be configured as follows: Figure 6 The vacuum cleaner 100 is shown to employ a dual-layer filter structure.

[0082] exist Figure 6In the cleaning appliance assembly 101 shown, not only is a filter 141 disposed within the first housing 110 of the vacuum cleaner 100, but also a filter 153 is disposed. The filter 153 is disposed upstream of the filter 141 in the flow direction of the air flowing from the dust collection chamber 146 toward the drive chamber 144, and a space 154 is formed between the filter 141 and the filter 153.

[0083] The mesh size of filter 153 is larger than that of filter 141, and filter 153 functions as a primary filter. Meanwhile, filter 141 functions as a secondary filter. Furthermore, to suppress fuzzing of filter 153, similar to filter 141, filter 153 can also be formed from a resin sheet with numerous vent holes.

[0084] If the suction source 142 generates an upward suction force, dust particles larger than the mesh size of the filter 153 are captured by the filter 153. On the other hand, dust particles smaller than the mesh size of the filter 153 pass through the filter 153 along with the air. However, these small dust particles can be captured by the filter 141, which is configured downstream of the filter 153.

[0085] Figure 6 The filter 153 of the cleaning appliance assembly 101 shown is in the form of a thin, flat plate. Instead, as... Figure 7 As shown, the filter 153 can also be formed as a cup with a downward opening. In this case, the filter 153 can have a larger surface area, and the overall clogging of the filter 153 is suppressed.

[0086] exist Figure 6 In the cleaning appliance assembly 101 shown, the mesh size of filter 141 is smaller than that of filter 153. However, if filter 141 is configured to isolate suction source 142 from user, the mesh size of filter 141 may be larger than that of filter 153.

[0087] exist Figure 1 In the cleaning appliance assembly 101 shown, air flowing in through inlet 149 passes through filter 141. In this case, filter 141 may act as a resistance unit to reduce the amount of air flowing in through inlet 149. To reduce the effect of this resistance unit, such as... Figure 8 As shown, the inlet 149 can also be formed at the opening of the dust storage chamber 146.

[0088] Figure 8The inlet 149 shown is open near the surface of the filter 141 facing the dust collection chamber 146 (i.e., the lower surface of the filter 141) so that a portion of the air passing through the inlet 149 flows along that surface. The present inventors believe that a large amount of dust adheres to the surface of the filter 141 facing the dust collection chamber 146, and therefore, based on the flow of air flowing in through the inlet 149 along that surface, dust separation from the filter 141 can be facilitated.

[0089] Figure 8 The inlet 149 shown opens on the rear surface of the first housing 110 near the side of the filter 141 facing the dust collection chamber 146. Therefore, a portion of the air flowing through the inlet 149 flows forward. In this case, it is also possible to... Figure 9 The pleated filter shown is filter 141. Figure 9 The filter 141 shown has a plurality of strip-shaped protrusions 151 extending in the front-to-back direction on its surface. The direction in which these strip-shaped protrusions 151 extend is approximately the same as the direction of airflow along the filter 141 through the inlet 149. Therefore, the air flowing in from the inlet 149 is not disturbed by these strip-shaped protrusions 151 and can flow along the surface of the filter 141. In addition, by forming the strip-shaped protrusions 151, the surface area of ​​the filter 141 is increased, thus preventing the filter 141 from becoming clogged. Furthermore, when the inlet 149 is open on the right or left surface of the first housing 110, the filter 141 can be fixed in the first housing 110 with the direction of extension of the strip-shaped protrusions 151 being in the left-to-right direction.

[0090] In the case where an inlet 149 is formed at a location communicating with the dust storage chamber 146, such as Figure 10 As shown, a dual-layer filter structure can also be used for the vacuum cleaner 100. That is, in Figure 10 In the vacuum cleaner 100 shown, a filter 153 is disposed upstream of the filter 141 in the direction of airflow from the dust collection chamber 146 toward the drive chamber 144. A space 154 is formed between these filters 141 and 153. An inlet 149 is formed in communication with this space 154.

[0091] exist Figure 10 In the vacuum cleaner 100 shown, air flowing into the space 154 through the inlet 149 passes through the filter 153. At this time, dust that is causing blockage in the filter 153 is stripped from the filter 153 and can fall into the dust collection chamber 146. As a result, the blockage in the filter 153 can be eliminated.

[0092] Figure 10 The filter 153 of the vacuum cleaner 100 shown is in the form of a thin, flat plate. Instead, as... Figure 7As shown, the filter 153 can also be formed as a cup with a downward opening. In this case, the filter 153 can have a larger surface area, and the overall clogging of the filter 153 is suppressed.

[0093] exist Figure 1 In the cleaning appliance assembly 101 shown, the user can manually move the cover 148 between the open position of the dust vent 147 and the closed position of the dust vent 147. Alternatively, it can also be done as follows: Figure 11 As shown, a first force-applying part 152 (e.g., a torsion spring) is provided at the connection between the cover 148 and the first housing 110 to automatically shift the cover 148 from the open position to the closed position. Based on the first force-applying part 152, the cover 148 is pressed towards the closed position of closing the dust outlet 147.

[0094] In this configuration, the suction source 219 of the recycling device 200 is configured to generate a suction force sufficient to cause the cover 148 of the vacuum cleaner 100 mounted on the recycling device 200 to rotate towards the open position against the force of the first force-applying part 152. If the cleaning appliance assembly 101 is configured in this way, the dust outlet 147 remains closed until the suction source 219 is operating. Therefore, dust leakage from the dust outlet 147 is suppressed. Subsequently, if the suction source 219 operates, the cover 148 rotates from the closed position to the open position based on the suction force of the suction source 219. When dust collection from the vacuum cleaner 100 to the recycling device 200 is completed, the suction source 219 stops. In this state, since no suction force is generated, the cover 148 returns from the open position to the closed position based on the force of the first force-applying part 152.

[0095] When the suction power of the suction source 219 is used to move the cover 148 from the closed position to the open position, a relatively large suction power is required from the suction source 219. To prevent the required suction power from the suction source 219 from becoming excessive, the cleaning appliance assembly 101 can also... Figure 12 It is constructed as shown.

[0096] exist Figure 12 In the cleaning appliance assembly 101 shown, a cover operation portion 221 protruding from the lower end of the dust inlet 215 is provided in the second housing 212 of the recycling device 200. Furthermore, a rotating shaft portion 155 is provided on the cover 148 for rotatably connecting the cover 148 to the first housing 110 of the vacuum cleaner 100. A first force-applying portion 152 is installed on this rotating shaft portion 155, and the cover 148 is pressed into a closed position by the first force-applying portion 152.

[0097] like Figure 13As shown, when the vacuum cleaner 100 is installed in the recycling device 200, the rotating shaft portion 155 is positioned higher than the cover operating portion 221. If the first housing 110 is pushed towards the second housing 212, the portion of the cover 148 positioned lower than the rotating shaft portion 155 is pushed backward by the cover operating portion 221, causing the cover 148 to rotate about the rotating shaft portion 155. That is, the cover 148 rotates from... Figure 12 The closed position shown Figure 13 The open position is shifted as shown.

[0098] exist Figure 12 and Figure 13 In the cleaning appliance assembly 101 shown, the vacuum cleaner 100 is pushed towards the recycling device 200, thereby pressing the cover 148 against the cover operating part 221. Furthermore, as long as the cover 148 is pressed against the cover operating part 221, the cover 148 is held in the open position. Therefore, the recycling device 200 can also generate a relatively large suction force to hold the cover 148 in the open position without resisting the force of the first force application part 152.

[0099] If the vacuum cleaner 100 is removed from the recycling device 200, the cover 148 of the vacuum cleaner 100 leaves the cover operating section 221 of the recycling device 200. In this state, the cover 148 automatically returns to its original position based on the force of the first force application section 152. Figure 12 The closed position is shown. Therefore, the user does not need to manually return the cover 148 to the closed position.

[0100] The discloser can foresee that a portion of the dust flowing from the vacuum cleaner 100 to the collection device 200 may fall between the vacuum cleaner 100 and the collection device 200. To suppress this dust falling, such as... Figure 14 As shown, a leakage prevention section 103 that circumferentially surrounds the dust inlet 215 may also be installed on the recycling device 200. Furthermore, the leakage prevention section 103 is sized such that, when the vacuum cleaner 100 is connected to the recycling device 200, it circumferentially surrounds not only the dust inlet 215 but also the dust outlet 147 of the vacuum cleaner 100 between the vacuum cleaner 100 and the recycling device 200. The leakage prevention section 103 may, for example, be formed of a sealing material capable of elastic compression and deformation.

[0101] As a compression section 102 of the compression leakage prevention section 103 when the vacuum cleaner 100 is installed in the recycling device 200, a magnet 223 is installed on the upper side of the leakage prevention section 103. Furthermore, as... Figure 15As shown, the vacuum cleaner 100 is provided with a magnetic body 156 that is magnetically attracted by the magnet 223 when the vacuum cleaner 100 is installed in the recycling device 200. The magnetic body 156 is positioned at a height that contacts the magnet 223 of the recycling device 200 when the vacuum cleaner 100 is installed in the recycling device 200. The magnetic attraction force acting between the magnetic body 156 and the magnet 223 functions as a compressive force that elastically compresses and deforms the upper part of the leakage prevention part 103.

[0102] In order to obtain a compressive force that causes the lower part of the leakage prevention part 103 to elastically compress and deform, the compression part 102 also has, for example, the compression part 102 has ... Figure 14 The strip-shaped protrusion 224 is shown protruding upward from the upper surface of the base plate 211. The strip-shaped protrusion 224 extends in the left-right direction on the base plate 211.

[0103] Users can Figure 16 The vacuum cleaner 100 is installed in the recycling device 200 such that the rear end edge of the support 132 of the nozzle 130 abuts against the strip-shaped protrusion 224. In this state, the protrusion position of the strip-shaped protrusion 224 is determined by compressing the leakage prevention part 103 by the front surface of the first housing 110. Furthermore, in this state, the strip-shaped protrusion 224 restricts the rotation of the first housing 110 within the positioning part 214 about the axis of the first housing 110.

[0104] If the vacuum cleaner 100 is installed in the recycling device 200, the leakage prevention section 103 is compressed by the first housing 110 of the vacuum cleaner 100. As a result, the leakage prevention section 103 can be used to prevent dust flowing from the dust outlet 147 of the vacuum cleaner 100 into the dust inlet 215 of the recycling device 200 from falling into the gap between the vacuum cleaner 100 and the recycling device 200.

[0105] Furthermore, the leakage prevention unit 103 also suppresses wind noise that may occur when dust is collected from the vacuum cleaner 100 to the collection device 200. Without the leakage prevention unit 103, air outside the cleaning appliance assembly 101 might flow into the gap between the vacuum cleaner 100 and the collection device 200 due to the suction force of the suction source 219. If the velocity of the air flowing through this gap increases, wind noise may occur. On the other hand, by providing the leakage prevention unit 103, the inflow of air outside the cleaning appliance assembly 101 into the gap between the vacuum cleaner 100 and the collection device 200 can be prevented. Therefore, wind noise caused by air flowing through this gap can be suppressed.

[0106] exist Figures 14 to 16In the cleaning appliance assembly 101 shown, magnet 223 is mounted on the recycling device 200, and magnetic body 156 is mounted on the vacuum cleaner 100. Conversely, magnet 223 can also be mounted on the vacuum cleaner 100, and magnetic body 156 can be mounted on the recycling device 200.

[0107] exist Figures 14 to 16 In the cleaning appliance assembly 101 shown, the leakage prevention unit 103 is fixed to the recycling device 200. Alternatively, the leakage prevention unit 103 can also be fixed to the vacuum cleaner 100. In this case, the leakage prevention unit 103 is mounted on the first housing 110 of the vacuum cleaner 100 in such a way that it surrounds the dust outlet 147 in the circumferential direction.

[0108] (Second Implementation)

[0109] In the cleaning appliance assembly 101 of the first embodiment, the cover 138 is opened or closed based on the user's own operation. Instead, as... Figure 17 As shown, the cleaning appliance assembly 101 can also be configured such that the cover 138 is opened when the vacuum cleaner 100 is installed on the recycling device 200, and the cover 138 is closed when the vacuum cleaner 100 is separated from the recycling device 200.

[0110] exist Figure 17 In the cleaning appliance assembly 101 shown, the inlet 149 of the vacuum cleaner 100 is formed on the front surface of the first housing 110. Furthermore, the height of the second housing 212 of the recycling device 200 is higher than the height position of the inlet 149 of the vacuum cleaner 100 installed in the recycling device 200.

[0111] like Figure 18 As shown, an outlet 226 is formed within the positioning portion 214 of the second housing 212 of the recycling device 200. The height position of the outlet 226 is set to face the inlet 149 of the vacuum cleaner 100, which is positioned by the positioning portion 214 of the recycling device 200. In this case, air inside the second housing 212 of the recycling device 200 can flow into the first housing 110 of the vacuum cleaner 100 through the inlet 149.

[0112] The cover plate 138 is connected to the first housing 110 via a rotating shaft 157, and a second force-applying part 158 ​​is mounted on the rotating shaft 157. The second force-applying part 158 ​​presses the cover plate 138 towards the closed position, closing the inlet 149. Additionally, Figure 18 The cover 138 shown is in the open position of the open inlet 149, and a portion of the cover 138 enters the second housing 212 of the recycling device 200 through the outlet 226.

[0113] The rotating shaft portion 157 is positioned on the right side relative to the left end of the cover 138. If the portion of the cover 138 located on the left side relative to the rotating shaft portion 157 is pushed, the cover 138 can rotate from the closed position to the open position with the rotating shaft portion 157 as the center. The cover pushing portion 225 protrudes rearward from the second housing 212 to allow for pushing this portion. If the vacuum cleaner 100 is connected to the recycling device 200, the left end of the cover 138 is pushed rearward by the cover pushing portion 225, allowing the cover 138 to rotate towards the open position.

[0114] The structure surrounding the cover 148 located on the lower side of the cover plate 138 and... Figure 13 The structure shown is the same. That is, the cover 148 is pressed into the closed position by the first force application part 152. Furthermore, the cover 148 can be rotated into the open position by being pushed backward by the cover operation part 221 according to the installation of the vacuum cleaner 100 into the recycling device 200.

[0115] With the vacuum cleaner 100 installed in the recovery unit 200, the user can activate the suction source 219 of the recovery unit 200. At this time, based on the suction power of the suction source 219, air from the second housing 212 of the recovery unit 200 flows into the buffer space 145 within the first housing 110 of the vacuum cleaner 100 through the outlet 226 and inlet 149. This air then flows through the filter 141 into the dust collection chamber 146. As the air passes through the filter 141, dust adhering to the filter 141 can be removed using this air. The dust then falls into the dust collection chamber 146.

[0116] Air flowing into the dust storage chamber 146 pushes dust out of the dust storage chamber 146 through the dust discharge port 147. Then, the dust can flow into the dust collection section 216 through the recovery pipe 217.

[0117] Once the dust collection from the dust chamber 146 to the dust collection section 216 is complete, the user can remove the vacuum cleaner 100 from the collection device 200 and begin cleaning. When the vacuum cleaner 100 is removed from the collection device 200, the cover 148 and the cover plate 138 rotate to the closed position using the first force-applying part 152 and the second force-applying part 158, respectively. As a result, the dust outlet 147 and the inlet 149 are automatically closed upon removal of the vacuum cleaner 100 from the collection device 200.

[0118] In this state, since the inlet 149 is closed by the cover 138, airflow from the inlet 149 is prevented even when the suction source 142 of the vacuum cleaner 100 is operating. Therefore, the suction force of the suction source 142 acting on the suction space 134 of the nozzle 130 is not reduced by the air flowing in from the inlet 149, and dust on the floor can be sucked up with a strong suction force.

[0119] The dust is drawn into the dust storage chamber 146 through the suction pipe 136. At this time, the dust discharge port 147, which is connected to the dust storage chamber 146, is closed by the cover 148, thus preventing the leakage of dust from the dust storage chamber 146 during cleaning operations.

[0120] exist Figure 17 and Figure 18 In the cleaning appliance assembly 101 shown, as the suction source 219 of the recovery device 200 operates, air inside the second housing 212 of the recovery device 200 flows into the first housing 110 of the vacuum cleaner 100 through the inlet 149. At this time, air outside the first housing 110 and the second housing 212 can also flow into the inlet 149 through the gap between the vacuum cleaner 100 and the recovery device 200. If the air flows through the gap between the vacuum cleaner 100 and the recovery device 200 at a high speed, wind noise may occur.

[0121] To suppress this wind noise, such as Figure 19 As shown, the recycling device 200 is equipped with an inflow prevention section 104 that surrounds the outlet 226 circumferentially. In addition, the inflow prevention section 104 has the following size: when the vacuum cleaner 100 is connected to the recycling device 200, it surrounds not only the outlet 226 circumferentially between the vacuum cleaner 100 and the recycling device 200, but also the inflow inlet 149 of the vacuum cleaner 100 circumferentially.

[0122] Furthermore, on the lower side of the inflow prevention section 104, the leakage prevention section 103 is installed on the recycling device 200 in such a way that it surrounds the dust inlet 215 circumferentially. The leakage prevention section 103 and the inflow prevention section 104 can be formed, for example, from a sealing material that can be elastically compressed and deformed.

[0123] The magnet 223 of the compression section 102 is fixed to the second housing 212 of the recycling device 200 on the upper side of the inflow prevention section 104, so that not only the leakage prevention section 103 can be compressed, but also the inflow prevention section 104 can be compressed. Furthermore, as... Figure 20 As shown, the magnetic body 156 is fixed to the first housing 110 on the upper side of the inlet 149 in such a way that it contacts the magnet 223 when the vacuum cleaner 100 is installed in the recycling device 200.

[0124] With the rear end edge of the nozzle 130's support 132 abutting against the strip-shaped protrusion 224 of the compression section 102 protruding upward from the base plate 211, the user can insert the first housing 110 of the vacuum cleaner 100 into the positioning section 214 of the recycling device 200. When the vacuum cleaner 100 is thus installed in the recycling device 200, the leakage prevention section 103 and the inflow prevention section 104 are compressed by the first housing 110 of the vacuum cleaner 100. As a result, air from outside the first housing 110 and the second housing 212 is prevented from flowing into the gap between the first housing 110 and the second housing 212, thereby suppressing wind noise caused by this airflow.

[0125] exist Figure 19 and Figure 20 In this case, magnet 223 is installed in the recycling device 200, and magnetic body 156 is installed in the vacuum cleaner 100. Alternatively, magnet 223 can be installed in the vacuum cleaner 100, and magnetic body 156 can be installed in the recycling device 200.

[0126] Figure 19 The inflow prevention part 104 shown is fixed to the recycling device 200. Alternatively, the inflow prevention part 104 can also be fixed to the vacuum cleaner 100. In this case, the inflow prevention part 104 is installed in the first housing 110 of the vacuum cleaner 100 in such a way that it surrounds the inlet 149 in the circumferential direction.

[0127] Figure 18 The inlet 149 shown is formed to open into the buffer space 145. Alternatively, the inlet 149 may also be formed to open into the dust storage chamber 146.

[0128] Figure 17 The vacuum cleaner 100 shown has a single filter 141. Alternatively, the vacuum cleaner 100 can also be used with... Figure 10 The vacuum cleaner 100 shown also has a dual-layer filter structure. That is, a filter 153 may be added upstream of the filter 141 in the direction of airflow from the dust collection chamber 146 toward the drive chamber 144. In this case, the inlet 149 may also be provided in a manner that communicates with the space 154 between these filters 141, 153.

[0129] (Third implementation)

[0130] The collection device 200 of the cleaning appliance assembly 101 in the first and second embodiments is used to collect dust from the vacuum cleaner 100. Alternatively, the collection device 200 can also be configured to suck up dust from a floor surface. In this case, the collection device 200 can also be configured as follows: Figure 21 It is constructed as shown. Figure 21 The recycling device 200 shown is in a position to suck up dust from the floor surface, with the rear wall 213 facing upwards.

[0131] A wheel section 227 is rotatably mounted on the second housing 212. The wheel section 227 is positioned within the recovery device 200. Figure 21 In the posture shown, it is in contact with the floor surface and can roll on the floor surface.

[0132] In addition, the internal structure of the second housing 212 is similar to Figure 5 The structure is identical to that shown. The suction source 219 within the second housing 212 can generate suction power using electricity transmitted via the power cable 229. Therefore, compared to the vacuum cleaner 100, which operates using the power of the battery 143 via the suction source 142, the recovery device 200 can extract dust from the floor surface for a longer period of time. On the other hand, the movement range of the recovery device 200 is limited by the length of the power cable 229. Therefore, for cleaning in areas far from an external power source, the vacuum cleaner 100 is more suitable than the recovery device 200. By considering these differences in characteristics between the recovery device 200 and the vacuum cleaner 100, users can appropriately use both devices.

[0133] When the recycling device 200 is used to vacuum dust from the floor, the mounting cylinder 230 is inserted into the positioning part 214 of the recycling device 200. A suction pipe 231 extends from the mounting cylinder 230, and a suction nozzle 232 is installed at the distal end of the suction pipe 231.

[0134] An opening 233 is formed on the peripheral wall of the mounting cylinder 230, allowing the user to insert the mounting cylinder 230 into the positioning part 214 such that the opening 233 overlaps vertically with the upward-opening dust inlet 215 inside the positioning part 214 of the second housing 212. Figure 21 In this configuration, "215 or 233" indicates that the opening 233 and the dust inlet 215 overlap vertically. In this state, if the suction source 219 within the second housing 212 is operational, the suction force of the suction source 219 acts on the suction nozzle 232. Then, dust on the floor surface flows sequentially through the suction nozzle 232, the suction pipe 231, and the mounting cylinder 230 into the second housing 212. Inside the second housing 212, this dust can flow through the recovery pipe 217 into the dust collection section 216 within the second housing 212.

[0135] exist Figure 21 The second housing 212 of the recycling device 200 is equipped with wheels 227 to facilitate movement of the recycling device 200 on the floor. Alternatively, or additionally, the second housing 212 may also be provided with a handle formed in a way that allows a user to grip it. In this case, the user can grip the handle to lift the second housing 212 off the floor and move it.

[0136] In the cleaning appliance assembly 101 of the first and second embodiments, suction power is generated from the recovery device 200 to suck up the dust collection chamber 146 of the vacuum cleaner 100. Alternatively, this suction power can also be generated by a canister vacuum cleaner. In this case, the user can connect the suction hose of the canister vacuum cleaner to the dust outlet and operate the canister vacuum cleaner. Accordingly, the dust in the dust collection chamber 146 of the vacuum cleaner 100 can be recovered by the canister vacuum cleaner.

[0137] (Effects, etc.)

[0138] The vacuum cleaner 100 and cleaning appliance assembly 101 described above have the following features and achieve the following effects.

[0139] One aspect of the above-described embodiment relates to a vacuum cleaner comprising: a housing having a drive chamber and a dust collection chamber, the drive chamber housing a suction source that generates a suction force for sucking up dust, wherein dust and air flow into the dust collection chamber based on the suction force of the suction source; and a filter disposed within the housing, which on the one hand allows air flowing from the dust collection chamber toward the drive chamber to pass through, and on the other hand retains dust contained in the air in the dust collection chamber. The housing further comprises: a dust outlet communicating with the dust collection chamber in a manner that allows dust to be discharged from the dust collection chamber; an inlet that, when the suction force sucking up dust from the dust collection chamber acts on the dust outlet, allows air used to promote the discharge of dust through the dust outlet to flow in from outside the housing; and a cover for opening and closing the dust outlet. The inlet is open at a position relative to the suction source on the dust collection chamber side and relative to the dust outlet on the drive chamber side.

[0140] In the above configuration, the user can operate the suction source with the dust outlet closed in order to extract dust. In this case, based on the suction force of the suction source, dust flows into the dust storage chamber along with air. This air can flow towards the drive chamber through the filter, while the dust is retained in the dust storage chamber by the filter. As a result, the suction source is protected from dust, and dust accumulates in the dust storage chamber.

[0141] To expel dust accumulated in the dust collection chamber, the user can operate the cover to open the dust outlet. Furthermore, to suck out dust from the dust collection chamber, the user can apply suction force to the dust outlet. Based on this suction force, air from outside the housing flows into the housing through an inlet formed on the drive chamber side relative to the dust outlet. As a result, an airflow from the inlet towards the dust outlet is generated within the housing, and the dust in the dust collection chamber is expelled through the dust outlet based on this airflow.

[0142] The inlet is formed on the exhaust side relative to the suction source, thus reducing the likelihood of air colliding with the suction source as it flows in through the inlet. Consequently, the suction source does not create significant resistance to the airflow from the inlet towards the exhaust port within the housing, increasing the volume of air flowing in through the inlet. This enhances the force of the air used to expel dust from the vacuum cleaner's dust collection chamber.

[0143] In the above configuration, the filter can also be positioned at a distance from the suction source, forming a buffer space to prevent the filter from contacting the suction source. The inlet can also be formed in a position communicating with the buffer space.

[0144] In the above configuration, if suction force is applied to the dust outlet, air from outside the housing flows into the buffer space between the suction source and the filter to prevent the filter from contacting the suction source. This air then passes through the filter into the dust collection chamber and is discharged from the dust outlet. As the air passes through the filter, dust adhering to it is shed using this airflow. As a result, filter clogging can be reduced to some extent.

[0145] In the above configuration, the inlet can also be opened at a position relative to the filter on the dust outlet side, in a manner that communicates with the dust storage chamber.

[0146] In the above configuration, the inlet is located on the dust outlet side relative to the filter. Therefore, the airflow from the inlet to the dust outlet within the housing is not hindered by the filter. Consequently, the increased amount of air flowing into the housing through the inlet increases the force that pushes dust out of the dust storage chamber through the dust outlet.

[0147] In the above configuration, the vacuum cleaner may also include: a cover and an open / closed inlet / outlet.

[0148] In the above configuration, with the inlet closed by the cover, air is prevented from flowing into the housing through the inlet. Therefore, if the suction source operates with the inlet closed by the cover, the suction force of the suction source will not decrease due to air flowing into the inlet, thus preventing an increase in dust flowing into the dust collection chamber. On the other hand, when dust is discharged from the dust collection chamber through the exhaust port, the cover can be operated with the inlet open. If the suction force is applied to the exhaust port in this state, dust is pushed out of the dust collection chamber through the exhaust port based on the air flowing into the housing through the inlet.

[0149] In the above configuration, the vacuum cleaner may also include: a first force-applying part that presses the cover to a closed position to close the dust outlet; and a second force-applying part that presses the cover to a closed position to close the inlet.

[0150] In the above configuration, the first and second force-applying parts are used to prevent the cover and cover plate from unintentionally opening the dust discharge port and the inlet port. Therefore, during the operation of the suction source, it is prevented that dust will leak through the dust discharge port or air will flow in through the inlet port.

[0151] In the above configuration, the vacuum cleaner may also include another filter, which is arranged upstream of the filter in the direction of airflow from the dust collection chamber to the drive chamber, spaced apart from the filter, and allows airflow from the dust collection chamber to the drive chamber to pass through while capturing dust contained in the air. The inlet may also be formed in a way that connects the filter and the other filter.

[0152] In the above configuration, not only is a filter used, but another filter can also be used to remove dust contained in the air flowing from the dust storage chamber toward the drive chamber. Therefore, the amount of dust flowing into the drive chamber is reduced.

[0153] Another filter is positioned upstream of the filter in the direction of airflow from the dust collection chamber toward the drive chamber, thus it can capture more dust than the filter. Therefore, this other filter is more prone to clogging than the filter. An inlet is formed to connect the space between the filter and the other filter, thereby preventing clogging of the other filter. In this case, the air flowing in through the inlet passes through the other filter, stripping away dust adhering to it.

[0154] Furthermore, the side of the filter facing the other filter in the downstream configuration is also exposed to the flow of air entering through the inlet. Therefore, dust adhering to this side can also be stripped off by the air flowing in through the inlet.

[0155] In the above configuration, the mesh size of the other filter can also be larger than that of the filter.

[0156] In the above configuration, because the mesh size of the other filter is larger than that of the main filter, it is able to capture larger dust particles. Furthermore, the dust particles that have passed through the other filter are captured by the main filter.

[0157] As suction force acts on the exhaust port, the air flowing in from the inlet passes through another filter. Because the mesh of this other filter is larger, the resistance to the airflow exerted by the other filter is not excessive.

[0158] In the above configuration, the filter or another filter may also be formed from a resin sheet with vent holes.

[0159] When the filter is made of non-woven fabric, linting is prone to occur. When linting occurs, dust adhering to the filter becomes difficult to remove. In the above configuration, to avoid this, the filter or another filter is formed of a resin sheet, which suppresses linting.

[0160] Another aspect of the above-described embodiments relates to a cleaning appliance assembly including: the vacuum cleaner described above; and a recycling device formed in a manner that allows it to be connected to the vacuum cleaner, wherein, when the vacuum cleaner is connected to the recycling device, the suction force that draws out the dust from the dust storage chamber acts on the dust outlet to recycle the dust from the dust storage chamber.

[0161] In the above configuration, in order to empty the dust chamber of the vacuum cleaner, the user operates the cover to open the dust outlet and activates the recovery device, causing the suction force of the recovery device to act on the dust outlet. As a result, the dust in the dust chamber of the vacuum cleaner is sucked out of the dust chamber through the dust outlet and recycled into the recovery device.

[0162] In the above configuration, the recycling device may also have: a second housing, which is formed in a manner that can be connected to the housing of the vacuum cleaner, i.e., the first housing; and a cover operating part, which pushes the cover of the vacuum cleaner when the first housing of the vacuum cleaner is connected to the second housing, and causes the cover to operate in a manner that opens the dust outlet.

[0163] In the above configuration, if the user connects the vacuum cleaner housing, i.e., the first housing, to the second housing of the recycling device, the cover operating part of the recycling device pushes against the cover installed on the first housing of the vacuum cleaner. Accordingly, the cover operates to open the dust outlet. Therefore, by connecting the first housing of the vacuum cleaner to the second housing of the recycling device, the user can open the dust outlet.

[0164] In the above configuration, the second housing may also have a dust inlet facing the dust outlet formed in the first housing when the first housing of the vacuum cleaner is connected to the second housing. The recovery device may also include: a dust collection section for collecting dust recovered from the dust storage chamber of the vacuum cleaner; a recovery pipe for forming a flow path for dust flowing from the dust inlet to the dust collection section; and a suction source for generating suction force that draws dust from the dust storage chamber of the vacuum cleaner to the dust collection section through the recovery pipe when the first housing of the vacuum cleaner is connected to the second housing.

[0165] In the above configuration, if the user connects the first housing of the vacuum cleaner to the second housing of the recovery device, the cover operation unit pushes the cover, opening the vacuum cleaner's exhaust port. In this state, since the dust inlet and exhaust port formed on the second housing of the recovery device face each other, the vacuum cleaner's dust collection chamber is connected to the dust collection chamber via a recovery pipe that forms a flow path for dust from the dust inlet to the dust collection chamber. At this time, if the suction source generates suction force, the dust in the dust collection chamber is sucked out based on this suction force and recovered into the dust collection chamber via the recovery pipe.

[0166] In the above configuration, the recycling device may also include a positioning part that positions the first housing of the vacuum cleaner at a position where the dust inlet and the dust outlet face each other.

[0167] In the above configuration, when the user connects the first housing of the vacuum cleaner to the second housing of the recycling device, the first housing is positioned so that the dust outlet and the dust inlet face each other using the positioning part of the recycling device. As a result, it is easy to achieve communication between the dust collection chamber of the vacuum cleaner and the dust receiving part of the recycling device.

[0168] In the above configuration, the cleaning appliance assembly may also include: a leakage prevention unit, which is installed on the first housing or the second housing in such a way that it surrounds the dust outlet and the dust inlet in the circumferential direction when the first housing of the vacuum cleaner is connected to the second housing of the recycling device, and is capable of elastic deformation; and a compression unit, which generates a compressive force that causes the leakage prevention unit to elastically compress and deform when the first housing of the vacuum cleaner is connected to the second housing of the recycling device.

[0169] In the above configuration, if the first housing of the vacuum cleaner is connected to the second housing of the recycling unit, the leakage prevention section is compressed and deformed by the compressive force of the compression section. Since the leakage prevention section surrounds the dust discharge port and the dust inlet, it prevents dust flowing from the dust storage chamber of the vacuum cleaner to the dust collection section of the recycling unit from leaking at the connection between the first housing and the second housing.

[0170] In the above configuration, the second housing can also be configured such that the inlet formed in the first housing is not blocked when the first housing of the vacuum cleaner is connected to the second housing.

[0171] In the above configuration, even if the first housing of the vacuum cleaner is connected to the second housing of the recycling device, the second housing will not block the inlet formed in the first housing. Therefore, with the first housing connected to the second housing, if the vacuum source of the recycling device is operating, air outside the first housing can flow into the inlet without obstruction from the second housing. Then, the dust in the dust storage chamber is pushed out by this air and can flow into the dust collection section through the recycling pipe of the recycling device.

[0172] In the above configuration, the second housing may also have an outlet that faces the inlet formed in the first housing when the first housing of the vacuum cleaner is connected to the second housing.

[0173] In the above configuration, the second housing is allowed to be large enough to block the inlet formed in the first housing when the first housing of the vacuum cleaner is connected to the second housing. That is, even if the second housing is so large, when the first housing is connected to the second housing, the outlet formed in the second housing faces the inlet formed in the first housing. Therefore, when the first housing is connected to the second housing, if the suction source of the recycling device is operating, air inside the second housing can flow into the inlet. Then, the dust in the dust storage chamber is pushed out by this air and can flow into the dust collection section through the recycling pipe of the recycling device.

[0174] In the above configuration, the cleaning appliance assembly may also include: a mounting tube, which can be connected to the second housing when the first housing of the vacuum cleaner is not connected to the second housing of the recycling device; and a suction tube extending from the mounting tube. The mounting tube has an opening that coincides with the dust inlet when the mounting tube is connected to the second housing.

[0175] In the above configuration, with the first housing of the vacuum cleaner not connected to the second housing of the recovery device, the mounting cylinder can be connected to the second housing such that the opening of the mounting cylinder coincides with the dust inlet. If the suction source is operating in this state, dust can be sucked in through the suction pipe extending from the mounting cylinder based on the suction force of the suction source. The dust can then flow into the dust collection section through the mounting cylinder and the recovery pipe.

[0176] 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 connected to the vacuum cleaner, wherein, when the vacuum cleaner is connected to the recovery device, the suction force that draws out dust from the dust collection chamber acts on the dust outlet to recover the dust from the dust collection chamber. The recovery device includes: a second housing, configured to be connected to the housing of the vacuum cleaner, i.e., the first housing. An outlet is formed in the second housing, facing the inlet formed in the first housing when the first housing of the vacuum cleaner is connected to the second housing; and a cover-pushing part is installed in the second housing, which pushes the cover of the vacuum cleaner when the first housing of the vacuum cleaner is connected to the second housing, thereby opening the inlet.

[0177] In the above configuration, if the user connects the vacuum cleaner housing, i.e., the first housing, to the second housing of the recycling device, the cover-pushing part of the recycling device pushes against the cover plate installed on the first housing of the vacuum cleaner. Accordingly, the cover plate operates in a manner that opens the inlet. Therefore, by connecting the first housing of the vacuum cleaner to the second housing of the recycling device, the user can open the inlet.

[0178] In the above configuration, the recycling device may also include a positioning section that positions the first housing of the vacuum cleaner at a position where the inlet and outlet face each other.

[0179] In the above configuration, when the user connects the first housing of the vacuum cleaner to the second housing of the recycling device, the first housing is positioned with the inlet and outlet facing each other by the positioning part of the recycling device. As a result, it is easy to obtain a state in which air inside the second housing can flow into the inlet.

[0180] In the above configuration, the cleaning appliance assembly may also include: an inflow prevention section, which is installed on the first housing or the second housing in such a way that it surrounds the inlet and outlet in the circumferential direction when the first housing of the vacuum cleaner is connected to the second housing of the recycling device, and is capable of elastic deformation; and a compression section, which generates a compressive force that causes the inflow prevention section to elastically compress and deform when the first housing of the vacuum cleaner is connected to the second housing of the recycling device.

[0181] In the above configuration, if the first housing of the vacuum cleaner is connected to the second housing of the recycling device, the inflow prevention section is compressed and deformed by the compressive force of the compression section. Since this inflow prevention section surrounds both the inlet and outlet, it prevents air from flowing into the inlet through the narrow gap between the first and second housings. If air were allowed to flow through this narrow gap, wind noise might occur due to the higher air velocity passing through it. The inflow prevention section is provided to suppress this wind noise.

[0182] Another aspect of the above-described embodiments relates to a cleaning appliance assembly comprising: the aforementioned vacuum cleaner; and a recovery device formed to be connected to the vacuum cleaner, wherein, when the vacuum cleaner is connected to the recovery device, the suction force that draws out dust from the dust collection chamber acts on the dust discharge port to recover the dust in the dust collection chamber. The recovery device comprises: a second housing formed to be connected to the housing of the vacuum cleaner, i.e., the first housing. The second housing comprises: a dust inlet facing the dust discharge port formed in the first housing when the first housing of the vacuum cleaner is connected to the second housing; and an outlet facing the inlet formed in the first housing when the first housing of the vacuum cleaner is connected to the second housing. The second housing also comprises: a cover operating part that pushes the cover of the vacuum cleaner when the first housing of the vacuum cleaner is connected to the second housing, thereby opening the dust discharge port; and a pushing part that pushes the cover flap of the vacuum cleaner, thereby opening the inlet flap.

[0183] In the above configuration, if the user connects the first housing of the vacuum cleaner to the second housing of the recycling device, the cover operating part and the cover pushing part respectively push the cover body and the cover plate, opening the dust outlet and the inlet. If the first housing is removed from the second housing, the cover body and the cover plate are moved to the closed position by the first force applying part and the second force applying part. As a result, the dust outlet and the inlet are separated from the second housing by the first housing and closed by the cover body and the cover plate.
