Description

Dust collector and recovery device for recovering dust from dust collector

Technical Field

The present invention relates to a dust collector and a dust collector for collecting dust from the dust collector.

Background

Patent document 1 discloses a stick-type vacuum cleaner. The vacuum cleaner includes a cleaner body, a suction pipe extending downward from the cleaner body, a suction nozzle connected to a lower end of the suction pipe, and a rod-shaped grip extending upward from the cleaner body. The grip portion is configured to be gripped by a user, and when the user grips the grip portion and moves the cleaner forward, the suction nozzle moves on the floor surface. A suction space for sucking dust is formed inside the suction nozzle. The cleaner body is configured to suck dust through the suction nozzle and store the sucked dust.

Specifically, the cleaner body includes a rectangular box-shaped housing, and a dust suction source for generating a suction force for sucking dust and a dust storage portion for storing dust flowing into the housing by the suction force of the dust suction source are disposed in the housing. A discharge port for discharging dust accumulated in the dust storage portion is formed in the rear wall of the housing. Further, a cover for opening or closing the discharge port is mounted to the frame.

The cover is swingably attached to the frame around a swing shaft portion provided at an upper end of the discharge port. The cover closes the discharge port in a state of sagging relative to the swing shaft. When the cover swings upward from this state, the discharge port is opened.

In patent document 1, a recovery device is used for recovering dust stored in a dust storage portion of a dust collector. The recovery device has a rectangular box-shaped frame, and the cleaner is held by the front wall of the frame. The frame is internally provided with: a suction source for generating a suction force for sucking out dust in a dust storage part of the dust collector; a collection chamber for accumulating dust collected from the cleaner based on a suction force of the suction source; and a dust flow path extending from the recovery chamber.

The distal end of the dust flow path opens as a recovery port in the front wall of the housing. The recovery port is formed at a height position overlapping with the discharge port of the dust collector mounted on the recovery device in the front-rear direction.

An annular protruding portion that surrounds the recovery port and protrudes forward is provided on the front wall of the housing of the recovery device. The protruding portion is fitted to an annular protruding portion surrounding the discharge port of the cleaner.

When the suction source of the recovery device is operated in a state where the cleaner is mounted to the recovery device, the suction force of the suction source acts on the cover of the cleaner via the dust flow path. The cover swings upward about the swing shaft portion from a state of sagging with respect to the swing shaft portion based on a suction force of the suction source. As a result, the discharge port of the cleaner is opened, and the suction force of the suction source acts on the dust in the dust storage portion. The dust in the dust storage part flows into the recovery chamber through the discharge port, the recovery port and the dust flow path in this order based on the suction force.

Assume that: when the cleaner is attached to the recovery device, the annular protruding portions of the cleaner body and the recovery device are not fitted to each other. In this case, a part of the dust moving from the discharge port of the cleaner body toward the collection port of the collection device may fall into the space between the collection device and the cleaner body.

(integral Structure of vacuum cleaner)

Fig. 1 is a schematic cross-sectional view of a stick cleaner 100. Fig. 2 is a front view of the cleaner 100. The cleaner 100 will be described with reference to fig. 1 and 2.

The vacuum cleaner 100 includes: a suction nozzle 130 for sucking dust on the floor; a cleaner body 110 attached to the suction nozzle 130 so as to be tiltable in the front-rear direction with respect to the suction nozzle 130; a grip 140 extending upward from the upper end 112 of the cleaner body 110. The cleaner body 110 and the grip 140 shown in fig. 1 and 2 are in an upright posture with respect to the suction nozzle 130, and do not tilt forward from the upright posture. In use of the cleaner 100, the cleaner body 110 and the grip 140 are held by a user in a posture of tilting backward with respect to the nozzle 130.

The suction nozzle 130 includes a nozzle housing 132 having a width wider than that of the cleaner body 110 so as to form a wide suction space 131 for sucking dust. The nozzle housing 132 is wide in the width direction, and can support the cleaner body 110 and the grip 140 in a state in which the cleaner body 110 and the grip 140 in the upright posture are less likely to tilt in the left-right direction. That is, as long as the upright cleaner body 110 and the grip 140 are not subjected to external force, the suction nozzle 130 can support the cleaner body 110 and the grip 140 in a state in which the upright posture of the cleaner body 110 and the grip 140 is maintained.

The internal space of the nozzle case 132 functions as a suction space 131 for sucking dust on the floor. The suction space 131 is opened toward the floor at a front side portion of the suction nozzle housing 132. On the rear side of the opening portion, the suction space 131 is closed based on the bottom 134 of the suction nozzle housing 132. A rotary cleaning brush 133 is disposed in the suction space 131, and the cleaning brush 133 is exposed from the nozzle housing 132 through an opening of the suction space 131 so as to be contactable with the floor.

The cleaner body 110 has a frame 111 elongated in the up-down direction. The lower end of the frame 111 is attached to the rear of the nozzle housing 132 so as to allow the cleaner body 110 to tilt in the front-rear direction. The upper portion of the housing 111 is narrower toward the upper end 112 of the housing 111, and the grip 140 extends upward from the upper end 112. The grip 140 is a thick and thin rod-shaped portion that is gripped by a user. As shown in fig. 2, the grip 140 is provided with an operation portion 141 (operation button) that is operated by a user.

Various members for sucking up dust on the floor and storing the sucked dust are disposed inside the housing 111. As shown in fig. 1, a suction pipe 113 extending in the vertical direction is disposed in the lower portion of the housing 111, and a check valve 114 is attached to the upper end of the suction pipe 113. A dust storage portion 115 and a dust collection source 116 provided above the dust storage portion 115 are provided above the check valve 114. A battery 117 for supplying electric power to the dust collection source 116 is disposed above the dust collection source 116. The dust suction source 116 is configured to receive electric power from the battery 117 and generate upward suction force in accordance with an operation of the operation unit 141. For example, the suction source 116 may be provided with a fan and a motor.

The suction pipe 113 is fixed to the housing 111, and when the cleaner body 110 is tilted rearward from the upright posture (posture shown in fig. 1), it is tilted rearward together with the housing 111. When the cleaner body 110 is in the upright posture, the lower end of the suction pipe 113 is brought into contact with the bottom 134 of the nozzle housing 132. That is, when the cleaner body 110 is in the upright posture, the lower end of the suction pipe 113 is closed based on the bottom 134 of the suction nozzle housing 132. When the cleaner body 110 is tilted rearward from the upright posture, the lower end of the suction pipe 113 moves in the direction indicated by the arrow a in fig. 1. As a result, the internal space of the suction pipe 113 is in communication with the suction space 131 of the nozzle housing 132.

A check valve 114 is mounted to the upper end of the suction pipe 113 to close the upper end of the suction pipe 113 when the dust collection source 116 is not in operation. Specifically, only the rear end portion of the check valve 114 is fixed to the suction pipe 113, and the remaining portion is allowed to be separated from the upper end of the suction pipe 113 when an upward external force is applied. The check valve 114 may also be formed, for example, from a thin rubber sheet. In this case, when the dust suction source 116 is operated, the check valve 114 is bent upward by the upward suction force of the dust suction source 116, and the opening of the upper end of the suction pipe 113 can be opened.

The dust storage portion 115 is fixed in the housing 111 at a position spaced upward from the check valve 114 so as not to interfere with the check valve 114 which is bent upward. The dust storage portion 115 is provided to prevent inflow of dust into the dust suction source 116.

The dust storage portion 115 has a container shape with a downward opening, and the inner space of the dust storage portion 115 is used as a dust storage space for storing dust. Specifically, as shown in fig. 3, the dust storage portion 115 includes a mesh filter 118 forming the peripheral surface and the upper side surface of the dust storage portion 115, and a holding frame 119 configured to hold the mesh filter 118. The mesh filter 118 allows air to pass therethrough on the one hand, and traps dust contained in the air on the other hand. As a result, dust sucked up by the suction force of the dust suction source 116 is stored in the dust storage space surrounded by the mesh filter 118.

In order to avoid interference with the check valve 114, the dust storage portion 115 is disposed at a position spaced upward from the check valve 114. Therefore, as shown in fig. 1 and 4, the space between the dust storage portion 115 and the check valve 114 functions as a communication passage 120 that is used for discharging dust stored in the dust storage portion 115. As shown in fig. 4, the front wall of the housing 111 is formed with a discharge port 124 that opens to the communication passage 120. The discharge port 124 is directed forward when the frame 111 is in the upright posture. The cover 121 is attached to the housing 111 to open and close the discharge port 124.

A swing shaft 123 rotatable about a substantially horizontal axis is provided on the front wall of the housing 111 and below the discharge port 124, and the cover 121 is configured to swing up and down about the swing shaft 123. The lid 121 shown in fig. 1 is in an upright posture, and is in a closed posture for closing the discharge port 124. At this time, the swing shaft 123 is located at the lower end of the cover 121. On the other hand, the lid 121 shown in fig. 4 swings downward by a predetermined angle (swing angle of 90 ° or less) from the closed state. When the cover 121 is in the posture shown in fig. 4, the cover 121 is inclined upward with respect to the swing shaft 123, and is separated from the discharge port 124. That is, the lid 121 is in an open position to open the discharge port 124.

The swing shaft 123 may be provided with a biasing member 150 for biasing the lid 121 toward the closed position. For example, the urging member 150 may be formed of a torsion spring wound around the swing shaft 123 so as to apply an upward swinging-direction urging force to the cover 121.

The cover 121 is provided with a notch 125 recessed in a cross-section V. On the other hand, a stopper 126 protruding into the notch 125 is provided on the front wall of the housing 111. The stopper 126 contacts the lid 121 when the lid 121 swings downward from the closed position by a predetermined angle.

Specifically, the notch 125 has: a lower edge surface 127 which approaches the stopper 126 when the cover 121 swings downward; the upper edge surface 128 is separated from the stopper 126 when the cover 121 swings downward. The lower edge surface 127 is configured to abut against the stopper 126 before the cover 121 swinging downward becomes a horizontal posture. As a result, the cover 121 is held by the housing 111 in an open posture inclined upward with respect to the swing shaft portion 123, and does not swing downward beyond the open posture of fig. 4. The upper edge surface 128 is formed so as not to prevent the lid 121 from being closed, and may be separated from the stopper 126 when the lid 121 is closed.

(integral Structure of recovery device)

The dust stored in the dust storage portion 115 can be recovered by the recovery device 200 shown in fig. 5. The recovery device 200 includes: a frame 210; the base plate 220 is mounted with the housing 210 at the front and the cleaner 100 at the rear. A dust flow path 230 having one end opened to the outside of the housing 210 is provided in the housing 210 of the recovery device 200 so as to allow dust recovered from the cleaner 100 to flow in. The other end of the dust flow path 230 is connected to the collection chamber 240, and a suction source 250 is disposed below the collection chamber 240. The suction source 250 is electrically connected to the control part 260 in the housing 210, and operates under the control of the control part 260.

The housing 210 includes: an upper portion 212 that accommodates the dust flow path 230, the collection chamber 240, and the suction source 250; the lower part 211 accommodates the control part 260. The upper portion 212 is a portion that contacts the cleaner body 110 when the cleaner 100 is mounted, so that the dust flow path 230 communicates with the communication path 120 of the cleaner 100. In order to avoid interference with the suction nozzle 130 protruding forward from the cleaner body 110, the lower portion 211 of the housing 210 is smaller in the front-rear direction than the upper portion 212, and a receiving space 213 for receiving the suction nozzle 130 is formed behind the lower portion 211.

The upper portion 212 of the housing 210 includes a rear wall 214 formed to be connectable with the cleaner body 110. In detail, as shown in fig. 6, a groove 215 complementary to the front portion of the cleaner body 110 is provided in the rear wall 214. As shown in fig. 7, the groove portion 215 is provided to extend in the up-down direction. The front portion of the cleaner body 110 in the upright posture is fitted into the groove portion 215.

As shown in fig. 7, a pair of small holes are formed in the groove portion 215 at the upper portion of the rear wall 214, and a pair of detection pieces 261 are provided which protrude from the outer side surface of the rear wall 214 through the small holes, respectively. These detection pieces 261 are used to detect the fitting of the cleaner body 110 into the groove portion 215.

The detection piece 261 is biased in a direction protruding from the rear wall 214, and is pushed into the small hole by the cleaner body 110 when the cleaner body 110 is fitted into the groove 215, so as to be immersed in the small hole. A signal generating unit 262 configured to detect whether or not the detection piece 261 is in a state of being immersed in the small hole and generate an activation signal when the detection piece 261 is detected to be immersed in the small hole is disposed in the housing 210. The signal generating unit 262 is electrically connected to the control unit 260 shown in fig. 5.

As shown in fig. 5, the dust flow path 230 is disposed in the upper portion 212 of the housing 210, and extends in the up-down direction. The upper end (other end) of the dust flow path 230 is connected to the recovery chamber 240. As shown in fig. 7, a lower end (one end) of the dust flow path 230 is formed with a recovery port 216 that opens in the rear wall 214 in the groove portion 215.

The recovery port 216 is formed at a position overlapping the discharge port 124 shown in fig. 4 in the front-rear direction when the cleaner 100 is placed on the base plate 220 in a state where the cleaner body 110 is in the upright posture and the front portion of the cleaner body 110 is fitted into the groove portion 215. That is, the collection port 216 faces the discharge port 124 of the cleaner 100 when the cleaner 100 is mounted to the collection device 200. The recovery port 216 is sized to allow the cover 121 of the cleaner 100 to enter the recovery port 216 when the cover 121 is in the open position of fig. 4.

The collection chamber 240 is provided for collecting dust flowing in from the dust storage portion 115 via the dust flow path 230. The recovery chamber 240 is configured to allow air inside the recovery chamber 240 to be sucked out based on a suction source 250 at the lower side of the recovery chamber 240. The recovery chamber 240 has a volume larger than the volume of the dust storage portion 115 provided in the cleaner 100.

The suction source 250 is configured to suck air in the recovery chamber 240. When the cleaner 100 is mounted to the collecting device 200, the suction force of the suction source 250 acts on the cover 121 of the cleaner 100 through the collecting chamber 240 and the dust flow path 230. The suction source 250 is configured to be capable of obtaining a suction force of a magnitude that tilts the cover 121 from the closed position to the open position against the biasing force of the biasing member 150 of the cover 121 and sucks dust in the dust storage portion 115. For example, the suction source 250 may be provided with a fan and a motor.

(description of operation of cleaner during cleaning operation)

The cleaner 100 is held by a user in a posture in which the cleaner body 110 and the grip 140 are inclined rearward with respect to the nozzle 130 during a cleaning operation. By making the cleaner body 110 and the grip 140 in a posture inclined backward with respect to the suction nozzle 130, it is easy to move the suction nozzle 130 forward while pushing it. In this state, the inner space of the suction pipe 113 communicates with the suction space 131 of the suction nozzle 130.

Thereafter, when the user operates the operation unit 141 to operate the dust suction source 116, the dust suction source 116 generates an upward suction force. Based on the suction force, the check valve 114 is bent and deformed upward. As a result, the upper end of the suction tube 113 is opened.

When the upper end of the suction pipe 113 is opened, suction force of the suction source 116 is applied to the suction space 131 of the suction nozzle 130, and dust on the floor is sucked into the suction space 131. Thereafter, the dust flows into the dust storage portion 115 through the suction pipe 113. The dust storage unit 115 captures dust and stores the captured dust.

When the user moves the suction nozzle 130 forward, the cleaner 100 may be impacted by the contact of the suction nozzle 130 with an obstacle. Since the lid 121 is biased by the biasing member 150 in a direction to close the discharge port 124, the discharge port 124 is hard to open even when the cleaner 100 receives an impact force. If the cover 121 swings due to the impact force and the discharge port 124 is once opened, the discharge port 124 is opened obliquely upward in a state where the cleaner body 110 is tilted rearward with respect to the suction nozzle 130. Therefore, the dust in the dust storage portion 115 is less likely to fall from the discharge port 124.

When the cleaning operation is completed, the user operates the operation unit 141 to stop the dust suction source 116. As a result, the suction force of the suction source 116 is lost, the check valve 114 returns to its original position, and the upper end of the suction pipe 113 is closed. Therefore, even if dust in the dust storage portion 115 falls from the dust storage portion 115, the dust remains in the communication passage 120.

(operation description of the recovery device during dust recovery)

The user attaches the cleaner 100 to the collection device 200 in order to collect dust stored in the dust storage portion 115 of the cleaner 100. Specifically, the user places the cleaner 100 on the base plate 220 of the recovery apparatus 200, and sets the cleaner body 110 and the grip 140 in an upright position. When the cleaner body 110 in the upright posture is fitted into the recess 215 of the recovery device 200, the lid 121 of the cleaner 100 faces the recovery port 216 of the recovery device 200 in the front-rear direction. Further, based on the cleaner body 110 fitted into the groove portion 215 of the recovery apparatus 200, the detection piece 261 of the recovery apparatus 200 is pressed forward so as to be immersed in the small hole of the rear wall 214.

The detection piece 261 is immersed in the small hole, and is detected by the signal generating unit 262. The signal generating unit 262 generates an activation signal based on the detection of the detection piece 261 being immersed in the small hole. The start signal is transmitted from the signal generating unit 262 to the control unit 260, and the control unit 260 operates the suction source 250 for a predetermined period in response to the reception of the start signal.

When the suction source 250 is operated, the suction force of the suction source 250 acts on the cover 121 facing the recovery port 216 through the recovery chamber 240 and the dust flow path 230. The cover 121 is tilted downward from the closed position closing the discharge port 124 as shown in fig. 8 by receiving the suction force of the suction source 250, and is opened to open the discharge port 124. At this time, the upper end portion of the cover 121 enters the lower end portion of the dust flow path 230 through the recovery port 216.

When the cover 121 swings downward, the discharge port 124 is opened. As a result, the dust storage space of the dust storage portion 115 is in communication with the collection chamber 240 through the communication passage 120, the collection port 216, and the dust flow path 230. Accordingly, the dust stored in the dust storage portion 115 flows into the recovery chamber 240 through the connection passage 120, the recovery port 216, and the dust flow path 230 in this order based on the suction force of the suction source 250. As a result, the dust is recovered in the recovery chamber 240.

Assume that: the cleaner 100 is attached to the recovery device 200 in such a state that the upper part of the cleaner body 110 is in a state of being fitted into the groove 215 to press the detection piece 261, but the lower part of the cleaner body 110 is in a state of being separated from the rear wall 214 of the recovery device 200. When the cleaner body 110 is mounted to the recovery apparatus 200 so as to incline, as shown in fig. 9, a space may be formed between the front side portion of the housing 111 of the cleaner 100 and the rear wall 214 of the recovery apparatus 200 around the recovery port 216 and the discharge port 124. Further, assume that: the discharge port 124 is opened obliquely downward, and dust falling from the dust storage portion 115 to the communication passage 120 is ejected from the discharge port 124 by gravity.

Dust scattered from the discharge port 124 by gravity is received by the cover 121. That is, the cover 121 is held in an open posture after swinging downward from the discharge port 124. Therefore, when the cover 121 is in the open position, the cover 121 protrudes toward the recovery device 200 below the discharge port 124 in a space between the front side portion of the housing 111 of the cleaner 100 and the rear wall 214 of the recovery device 200. Therefore, even if dust falls from the discharge port 124, the dust can be received by the cover 121.

At this time, the cover 121 of the cleaner 100 enters the interior of the recovery apparatus 200 through the recovery port 216 of the recovery apparatus 200. Therefore, the dust can move from the discharge port 124 of the cleaner 100 to the recovery port 216 of the recovery device 200 and flow into the recovery device 200 while being prevented from falling by the cover 121.

The suction source 250 of the recovery device 200 is stopped after a specified time of operation. At this time, dust may remain on the cover 121. Even if dust remains on the cover 121, the cover 121 is inclined upward with respect to the swing shaft 123, and therefore the dust slides down toward the swing shaft 123. Therefore, dust is prevented from being scattered from the distal end side of the cover 121. While the dust slides down toward the swing shaft 123, the cover 121 swings upward around the swing shaft 120 by the biasing force of the biasing member 150, and closes the discharge port 124. Therefore, the dust remaining on the cover 121 can be returned to the communication passage 120 between the dust storage portion 115 and the check valve 114 through the discharge port 124.

In the above embodiment, the cover 121 protrudes from the housing 111 of the cleaner 100 in a state of being inclined obliquely upward when the cover is in the open position. Alternatively, the cover 121 may protrude from the housing 111 of the cleaner 100 in a substantially horizontal posture when the cleaner is in the open posture.

In the above embodiment, the lid 121 swings up and down to be in the closed position or in the open position. Alternatively, the cover 121 may be detachable from the housing 111 of the cleaner 100 and may be attached to the housing 111 of the cleaner 100 in 2 positions, i.e., an open position and a closed position. In this case, when collecting dust from the collecting device 200, the user can detach the cover 121 in the closed position from the housing 111 of the cleaner 100, and thereafter attach the cover 121 to the housing 111 of the cleaner 100 in the open position. In this state, if the user attaches the cleaner 100 to the recovery apparatus 200 and operates the recovery apparatus 200, the dust flowing from the cleaner 100 to the recovery apparatus 200 can be prevented from falling down and can be recovered to the recovery apparatus 200. Thereafter, when the user uses the cleaner 100, the cover 121 in the open position is once removed from the housing 111 of the cleaner 100, and can be attached to the housing 111 of the cleaner 100 in the closed position. As a result, the user can use the cleaner 100 with the discharge port 124 closed by the cover 121.

In the above embodiment, the cleaner body 110 is attached to the suction nozzle 130 so as to be tiltable backward from the upright posture based on the operation of the user. Alternatively, the cleaner body 110 may not be capable of tilting backward. In this case, the cleaner 100 can be used in a state in which the cleaner body 110 is in an upright posture.

In the above-described embodiment, the cleaner body 110 is not tilted forward from the upright posture, but the cleaner body 110 may be allowed to tilt forward in a range in which the cover 121 in the release posture is maintained in a tilted upward posture.

(effects etc.)

The dust collector 100 and the recovery device 200 according to the above embodiment have the following features and the following effects.

The dust collector according to one aspect of the above embodiment is configured to be connectable to a collection device having a collection chamber for collecting dust. The dust collector comprises: a dust suction source for generating a suction force for sucking dust; a dust storage part having a dust storage space for storing dust sucked by the dust suction source; a communication passage formed to be capable of communicating the dust storage space with a recovery chamber of the recovery device in a state where the cleaner is connected to the recovery device; and a cover body for opening and closing the connecting channel. The cover opens the connecting channel in the state of receiving dust, so that the dust can not fall between the recovery device and the dust collector.

According to the above configuration, when the lid opens the connection passage in a state where the cleaner is connected to the recovery device, the dust storage space communicates with the recovery chamber of the recovery device. As a result, the dust in the dust storage space is allowed to be discharged to the recovery device through the connection passage. At this time, the cover opens the communication passage in a state of receiving dust, and therefore, the dust is prevented from falling between the cleaner and the recovery device.

In the above configuration, the lid may be configured to swing downward from a closed position closing the communication path, and to be capable of changing the position to an open position opening the communication path. The vacuum cleaner may further include: and a stopper for stopping the cover at a position where the cover swings by a predetermined angle and is inclined obliquely upward when the cover swings from the closed position to the open position.

According to the above configuration, after the lid swings downward by a predetermined angle from the closed position closing the connecting passage, the swing of the lid is stopped by the stopper. At this time, the cover is inclined obliquely upward, so that even if dust remains on the cover after the collection of dust into the collection device is completed, the dust returns to the cleaner side and is less likely to be scattered from the distal end of the cover.

In the above configuration, the cover may be configured to be swingable between a closed position closing the communication passage and an open position opening the communication passage. The vacuum cleaner may further include: and a biasing member for biasing the cover body toward the closed position.

According to the above configuration, the lid is biased to the closed position by the biasing member, and thus the lid is less likely to be unnecessarily opened. Therefore, for example, in a state where the cleaner is not attached to the recovery apparatus, the opening of the communication path can be suppressed.

In the above configuration, the vacuum cleaner may further include: a frame body forming a communication path and accommodating a dust suction source and a dust storage part; and a suction nozzle that sucks in dust based on a suction force of the dust suction source. The frame body can be attached to the suction nozzle so as to be tiltable backward from the upright posture based on the operation of the user. The cover may be provided to open and close the communication passage opened in the front wall of the housing.

According to the above configuration, the user can tilt the frame body backward with respect to the suction nozzle and perform the cleaning operation while pushing the suction nozzle. At this time, the connecting passage opened in the front wall of the housing is opened obliquely upward by tilting the housing rearward, and a gravity force in a direction to maintain the closed position acts on the lid closing the opening portion of the connecting passage. Therefore, the cover is difficult to be opened during cleaning.

The recovery device according to one aspect of the above embodiment is configured to be capable of mounting the above cleaner. Recovery device includes: a recovery chamber for recovering dust; a dust flow path, one end of which is connected with the recovery chamber and is communicated with the communication path in a state that the dust collector is mounted on the recovery device; and a suction source configured to apply suction force to the cover body so that the cover body is in an open position in which the connecting passage is opened, and to suck dust into the collection chamber through the connecting passage and the dust flow passage in a state in which the cover body is in the open position, when the dust collector is attached to the collection device. The cover is formed to enter the dust flow path when the cover is in the open position.

According to the above configuration, when the suction source applies suction force to the cover body and the cover body is opened in a state where the cleaner is attached to the collecting device, the dust flow path of the collecting device communicates with the communication path. In this state, the suction force of the suction source can act on the dust in the dust storage portion through the dust flow path and the communication path. Therefore, the dust in the dust storage space flows into the recovery chamber of the recovery device through the connecting passage and the dust flow passage. At this time, since the cover is brought into a state of entering the dust flow path, dust can move toward the other end portion of the dust flow path while being prevented from falling by the cover.

Industrial applicability

The dust collector and the recovery device according to the above embodiments can be suitably applied to a device used for cleaning work.
