Abstract

The present disclosure provides a cleaner and a cleaning implement set. The dust collector comprises a shell with a driving chamber containing a suction source and a dust storage chamber into which dust flows, and a filter for capturing the dust. A buffer space for preventing the filter from contacting the suction source is formed between the filter and the suction source. A dust discharge port communicating with the dust storage chamber in a manner allowing dust to be discharged from the dust storage chamber, and an inflow port allowing air for promoting dust to be discharged through the dust discharge port to flow in from outside of the housing in a state where a suction force sucking dust out of the dust storage chamber acts on the dust discharge port are formed in the housing, and a cover opening and closing the dust discharge port is mounted in the housing. The inflow port is formed at a position of the buffer space or communicating with the dust storage chamber so that air flowing in through the inflow port does not collide with the suction source. Accordingly, the force of air for discharging dust from the dust storage chamber of the dust collector can be increased.

Description

Dust collector and cleaning tool set Technical Field The present disclosure relates to a cleaner having a suction source that generates a suction force for sucking dust, and a cleaning implement group provided with the cleaner. Background Patent document 1 discloses a cleaning tool set 300 shown in fig. 22. The cleaning tool set 300 includes a stick-type dust collector 310 configured to suck dust on a floor surface, and a recovery device 320 configured to recover the dust from the dust collector 310. The vacuum cleaner 310 includes a substantially cylindrical housing 311 extending in the vertical direction, a grip 312 extending upward from the upper end of the housing 311, and a suction nozzle 313 provided on the lower side of the housing 311. A suction pipe 314 forming a flow path for dust is housed in a lower portion of the housing 311, and a lower end portion of the suction pipe 314 is connected to the suction nozzle 313. As shown in fig. 23, the inner space of the housing 311 on the upper side of the suction pipe 314 is divided into a dust storage chamber 315, a filter chamber 316 provided on the upper side of the dust storage chamber 315, and a driving chamber 317 provided on the upper side of the filter chamber 316. The dust storage chamber 315 is a space for storing dust passing through the suction nozzle 313 and the suction pipe 314. The filter chamber 316 is provided with a primary filter 318 configured to centrifugally separate dust contained in the air, and a secondary filter 319 for removing dust that has not been completely removed by the primary filter 318. A suction source 341 configured to generate an upward suction force is disposed in the driving chamber 317. When a user performs a cleaning operation using the cleaner 100, dust on the floor surface is sucked into the dust storage chamber 315 together with air through the suction nozzle 313 and the suction pipe 314 by the suction force of the suction source 341. Then, the air and dust flow into the filter chamber 316, and the dust is separated from the air by the primary filter 318 and the secondary filter 319 in the filter chamber 316. Accordingly, the dust-removed air flows into the driving chamber 317. After the suction source 341 in the driving chamber 317 is stopped, dust falls from the filter chamber 316 into the dust storage chamber 315. In order to discharge dust accumulated in the dust storage chamber 315, a dust discharge port 342 and an inflow port 343 are formed in the rear surface of the housing 311 as shown in fig. 23. The dust discharge port 342 is provided at a height position communicating with the dust storage chamber 315, and dust is discharged from the dust storage chamber 315 through the dust discharge port 342. The inflow port 343 is formed at a height position communicating with the driving 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 inflow port 343. The air passes through the driving chamber 317 and the filter chamber 316 in this order, and the dust in the dust storage chamber 315 is pushed out through the dust discharge port 342. As shown in fig. 22, the recovery device 320 includes a mounting portion 321 on which the suction nozzle 313 is mounted, and a substantially rectangular box-shaped casing 322 standing on the rear side of the mounting portion 321. As shown in fig. 24, a recess 323 is provided in the front wall of the housing 322 of the recovery device 320 so as to extend in the vertical direction, and the recess 323 is fitted into the rear portion of the housing 311 of the cleaner 310 in which the suction nozzle 313 is mounted in the mounting portion 321. Within the recess 323, the dust inlet 324 and the outflow 325 are open. The dust inlet 324 is formed at a height position facing the dust outlet 342 of the cleaner 310 having the suction nozzle 313 mounted on the mounting portion 321. The outflow port 325 is formed at a height position facing the inflow port 343 of the cleaner 310 having the suction nozzle 313 mounted on the mounting portion 321. The inner space of the housing 322 of the recovery device 320 communicates with the driving chamber 317 through the outflow port 325 and the inflow port 343 in a state where the cleaner 310 is connected to the recovery device 320. As shown in fig. 23, a dust accommodating portion 326 for accommodating dust collected from the cleaner 310 and a collection pipe 327 forming a flow path of dust flowing from the dust inlet 324 to the dust accommodating portion 326 are disposed in the housing 322. A dust collection source 328 that generates a dust collection force for sucking out dust from the dust collector 310 is disposed below the dust storage unit 326. The dust suction source 328 sucks air in the dust storage unit 326 downward. If the air in the dust accommodating portion 326 is sucked out by the dust suction source 328, the dust suction force of the dust suction source
