When the cleaner main body 110 is in an upright position, the lower end of the suction pipe 113 is in contact with the bottom 134 of the nozzle case 132 . That is, the lower end of the suction pipe 113 is closed by the bottom portion 134 of the nozzle case 132 when the cleaner main body 110 is in an upright posture. When the cleaner body 110 tilts backward from the upright posture, the lower end of the suction tube 113 moves in the direction indicated by arrow A in FIG. As a result, the internal space of the suction pipe 113 communicates with the suction space 131 of the nozzle case 132 .

A check valve 114 is attached to the upper end of the suction pipe 113 to block the upper end of the suction pipe 113 when the dust collection source 116 is not operating. 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 receive an upward external force and be separated from the upper end of the suction pipe 113. there is The check valve 114 may be composed of, for example, a thin rubber plate.

It is configured to rotate to The lid body 121 shown in FIG. 1 is in an upright position, and is in a closed position to close the outlet 124 . At this time, the rotating shaft portion 123 is positioned at the lower end of the lid body 121 . On the other hand, the lid body 121 shown in FIG. 4 is rotated downward by a predetermined angle (a rotation angle of 90° or less) from the state of the closed posture. When the lid body 121 is in the posture shown in FIG. 4, the lid body 121 is inclined upward from the rotation shaft portion 123 and away from the discharge port 124 . In other words, the cover 121 is in an open position to open the outlet 124 .

A biasing member 150 that biases the lid body 121 toward the closed posture may be provided on the rotating shaft portion 123 . For example, the biasing member 150 may be configured by a torque spring wound around the rotation shaft portion 123 so as to bias the lid body 121 in the upward rotation direction.

The lid 121 is provided with a notch 125 having a V-shaped cross section. On the other hand, the front wall of the housing 111 is provided with a stopper portion 126 protruding into the notch portion 125 .

The collection device 200 includes a housing 210 and a base plate 220 on which the housing 210 is installed at the front and the cleaner 100 is placed at the rear. Inside the housing 210 of the collection device 200, a dust flow path 230 is provided, one end of which is open to the outside of the housing 210 so that the dust collected from the cleaner 100 flows. The other end of the dust channel 230 is connected to a collection chamber 240, and a suction source 250 is arranged below the collection chamber 240. As shown in FIG. The suction source 250 is electrically connected to the controller 260 inside the housing 210 and operates under the control of the controller 260 .

The housing 210 has an upper portion 212 that accommodates the dust flow path 230, the collection chamber 240, and the suction source 250, and a lower portion 211 that accommodates the control section 260. Upper portion 212 is a portion that abuts cleaner main body 110 when cleaner 100 is attached so that dust channel 230 communicates with communication passage 120 of cleaner 100 . In order to avoid interference with the suction nozzle 130 projecting forward from the cleaner body 110, the lower portion 211 of the housing 210 is smaller than the upper portion 212 in the front-rear direction, and the suction nozzle 130 is located behind the lower portion 211. An accommodation space 213 is formed for accommodating the .

An upper portion 212 of the housing 210 includes a rear wall 214 that is connectable with the cleaner body 110 . Specifically, the rear wall 214 is provided with a groove 215 complementary to the front portion of the cleaner body 110, as shown in FIG. As shown in FIG. 7, the groove 215 extends vertically. A front portion of the cleaner main body 110 in an upright position is fitted into the concave groove portion 215 .

These detection pieces 261 are used to detect that the cleaner main body 110 has been fitted into the concave groove portion 215 .

The detection piece 261 is biased in a direction protruding from the rear wall 214, and when the cleaner body 110 is fitted into the recessed groove 215, it is pushed into the small hole by the cleaner body 110 and sinks into the small hole. become a state. A signal generation unit configured to detect whether or not the detection piece 261 is in a state of being retracted into the small hole, and to generate an activation signal when the detection piece 261 is detected to be inserted into the small hole. 262 is located within housing 210 . The signal generator 262 is electrically connected to the controller 260 shown in FIG.

As shown in FIG. 5, the dust channel 230 is arranged in the upper part 212 of the housing 210 and extends vertically. The upper end (other end) of the dust channel 230 is connected to the collection chamber 240 . A lower end (one end) of the dust flow path 230 forms a collection port 216 that opens in the rear wall 214 in the recessed groove 215 as shown in FIG.

When the cleaner 100 is placed on the pedestal plate 220 with the cleaner main body 110 in an upright position and the front portion of the cleaner main body 110 is fitted into the recessed groove 215, the recovery port 216 is opened as shown in FIG. 4 overlaps in the longitudinal direction with the discharge port 124 shown in FIG. That is, the collection port 216 faces the discharge port 124 of the cleaner 100 when the cleaner 100 is attached to the collection device 200 . The recovery port 216 has a size such that the lid 121 can enter the recovery port 216 when the lid 121 of the cleaner 100 is in the open position shown in FIG.

The collection chamber 240 is provided for collecting dust that has flowed from the dust storage section 115 through the dust flow path 230 . Collection chamber 240 is configured to allow air within collection chamber 240 to be sucked by suction source 250 below collection chamber 240 .

The suction source 250 is configured to suck the air inside the recovery chamber 240 . The suction force of the suction source 250 acts on the cover 121 of the cleaner 100 through the collection chamber 240 and the dust channel 230 when the cleaner 100 is attached to the collection device 200 . The suction source 250 overcomes the biasing force of the biasing member 150 of the lid 121 , tilts the lid 121 from the closed posture to the open posture, and obtains a suction force large enough to suck the dust in the dust container 115 . configured to be For example, suction source 250 may consist of a fan and a motor.

(Description of the operation of the vacuum cleaner during cleaning work)
During cleaning work, the cleaner 100 is held by the user in a posture in which the cleaner body 110 and the grip portion 140 are tilted backward with respect to the suction nozzle 130 . By slanting the cleaner body 110 and the grip portion 140 backward with respect to the suction nozzle 130, it becomes easier to move the suction nozzle 130 forward while pushing it. In this state, the internal space of the suction pipe 113 communicates with the suction space 131 of the suction nozzle 130 .

When the user then operates the operation unit 141 to activate the dust suction source 116, the dust suction source 116 generates an upward suction force. This suction force bends and deforms the check valve 114 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, the suction force of the dust suction source 116 acts on the suction space 131 of the suction nozzle 130, and dust on the floor is sucked into the suction space 131. The dust then passes through suction tube 113 and flows into dust storage section 115 . Dust storage unit 115 captures dust and stores the captured dust.

When the user is moving the suction nozzle 130 forward, the suction nozzle 130 may come into contact with an obstacle and the cleaner 100 may receive an impact. Lid 121 is urged in a direction to close outlet 124 by urging member 150, and even when cleaner 100 receives an impact force, outlet 124 is difficult to open. Even if the cover 121 is rotated by the impact force and the discharge port 124 is temporarily opened, the discharge port 124 is not opened when the cleaner main body 110 is tilted backward with respect to the suction nozzle 130. It is open obliquely upward. Therefore, the dust in dust storage unit 115 is less likely to fall from outlet 124 .

When the cleaning work is finished, the user operates the operation unit 141 to stop the dust collection source 116 . As a result, the suction force of the dust suction source 116 disappears, so the check valve 114 is restored and the upper end of the suction pipe 113 is closed. Therefore, even if the dust in dust storage portion 115 falls from dust storage portion 115 , the dust is retained in communication path 120 .

(Description of the operation of the collecting device when dust is collected)
A user attaches the cleaner 100 to the collecting device 200 in order to collect dust accumulated in the dust storage unit 115 of the cleaner 100 . Specifically, the user places the cleaner 100 on the base plate 220 of the collecting device 200, and puts the cleaner main body 110 and the grip part 140 in an upright posture. When the cleaner main body 110 in the upright position is fitted into the concave groove portion 215 of the recovery device 200 , the lid body 121 of the cleaner 100 faces the recovery port 216 of the recovery device 200 in the front-rear direction. Further, the detection piece 261 of the recovery device 200 is pushed forward by the cleaner main body 110 fitted in the recessed groove portion 215 of the recovery device 200 and sinks into the small hole of the rear wall 214 .

The signal generator 262 detects that the detection piece 261 has entered the small hole. The signal generator 262 generates an activation signal in response to detection of the insertion of the detection piece 261 into the small hole. The activation signal is transmitted from the signal generating section 262 to the control section 260, and the control section 260 operates the suction source 250 for a predetermined period in response to the reception of the activation signal.

When the suction source 250 operates, the suction force of the suction source 250 acts on the cover 121 facing the collection port 216 through the collection chamber 240 and the dust flow path 230 . The lid body 121 receives the suction force of the suction source 250, and as shown in FIG. At this time, the upper end portion of the lid body 121 enters the lower end portion of the dust channel 230 through the collection port 216 .

When the cover 121 rotates downward, the discharge port 124 is opened. As a result, the dust storage space of the dust storage section 115 communicates with the collection chamber 240 through the communication path 120 , the collection port 216 and the dust flow path 230 . Therefore, the dust stored in the dust storage unit 115 passes through the communication path 120 , the collection port 216 and the dust flow path 230 in order by the suction force of the suction source 250 and flows into the collection chamber 240 . As a result, dust is collected in the collection chamber 240 .

Although the upper part of the cleaner body 110 is fitted in the concave groove part 215 and presses the detection piece 261, the lower part of the cleaner body 110 is separated from the rear wall 214 of the collecting device 200. It is assumed that 100 is attached to retrieval device 200 . When the cleaner main body 110 is attached obliquely to the recovery device 200 in this way, the front portion of the housing 111 of the cleaner 100 and the front portion of the cleaner 100 around the recovery port 216 and the discharge port 124 as shown in FIG. A space may be created between the rear wall 214 of the collection device 200 . In addition, it is assumed that the dust that has fallen into the communication passage 120 from the dust storage section 115 spills out of the discharge port 124 due to gravity.

Dust falling from the outlet 124 due to gravity is received by the lid 121 . In other words, the cover 121 is held in an open position rotated downward from the outlet 124 . Therefore, when the lid 121 is in the open position, the lid 121 is positioned below the outlet 124 in the space between the front portion of the housing 111 of the vacuum cleaner 100 and the rear wall 214 of the recovery device 200. , project toward the recovery device 200 . Therefore, even if dust falls from the outlet 124, it is received by the lid 121. - 特許庁

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

The suction source 250 of the recovery device 200 stops after operating for a predetermined time. At this time, dust may remain on the lid 121 . Even if dust remains on the lid 121 , the dust slides down toward the rotation shaft 123 because the lid 121 is tilted upward from the rotation shaft 123 . Therefore, dust is prevented from dropping from the tip side of the lid body 121 . While the dust slides down toward the rotating shaft portion 123 , the biasing force of the biasing member 150 rotates the lid body 121 upward around the rotating shaft portion 120 to close the discharge port 124 . Therefore, dust remaining on lid 121 can be returned to communication path 120 between dust storage section 115 and check valve 114 through outlet 124 .

In the above-described embodiment, the lid 121 protrudes from the housing 111 of the vacuum cleaner 100 in an obliquely upwardly inclined state when it is in the open position. Alternatively, the lid 121 may protrude from the housing 111 of the cleaner 100 in a substantially horizontal position when in the open position.

Further, in the above-described embodiment, the lid body 121 is turned up and down to take the closed posture and the open posture. Alternatively, the lid body 121 may be configured to be detachable from the housing 111 of the cleaner 100 and attachable to the housing 111 of the cleaner 100 in two postures, an open posture and a closed posture. . In this case, when collecting dust into the collecting device 200, the user removes the lid body 121 in the closed position from the housing 111 of the cleaner 100 once, and then opens the lid body 121 in the housing of the cleaner 100 in the open position. 111 can be attached. In this state, when the user attaches the cleaner 100 to the collecting device 200 and operates the collecting device 200, the dust flowing from the cleaner 100 to the collecting device 200 is prevented from falling, and the dust is transferred to the collecting device 200. can be recovered. After that, when the user uses the cleaner 100, the lid 121 in the open position can be removed from the housing 111 of the cleaner 100 once, and 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 outlet 124 closed by the lid 121 .

Further, in the above-described embodiment, the cleaner main body 110 is attached to the suction nozzle 130 so as to be tiltable rearward from the upright posture by the operation of the user. Alternatively, the cleaner body 110 may not be tiltable backwards. In this case, the cleaner 100 can be used while the cleaner main body 110 is in an upright position.

In the above-described embodiment, the cleaner main body 110 does not tilt forward from the upright posture, but the cleaner main body 110 can be tilted forward within a range in which the lid body 121 in the open posture is inclined upward. Tilting may be allowed.

A vacuum cleaner according to one aspect of the above embodiment is configured to be connectable to a collection device having a collection chamber for collecting dust. A vacuum cleaner includes a dust suction source that generates a suction force for sucking dust, a dust storage unit that has a dust storage space that stores the dust sucked by the dust suction source, and a storage device in which the vacuum cleaner is connected to a collection device. It comprises a communicating path formed so that the dust space can be communicated with the collection chamber of the collecting device, and a cover for opening and closing the communicating path. The cover opens the communication path in a posture of receiving dust so that the dust does not fall between the collection device and the vacuum cleaner.

According to the above configuration, when the cover body opens the communication passage while the cleaner is connected to the collection device, the dust storage space communicates with the collection chamber of the collection device. As a result, the dust in the dust storage space is allowed to be discharged to the collection device through the communication passage. At this time, the cover body opens the communication path in a posture of receiving dust, so that the dust is suppressed from falling between the cleaner and the collection device.

In the above configuration, the lid body may be configured to be able to change its posture from the closed posture in which the communicating path is closed to the open posture in which the communicating path is opened by rotating downward. The vacuum cleaner has a stopper portion that stops the lid when the lid rotates from the closed posture toward the open posture, and the lid rotates by a predetermined angle to a position inclined obliquely upward. may be further provided.

According to the above configuration, the rotation of the lid is stopped by the stopper portion when the lid rotates downward by a predetermined angle from the closed position in which the communication passage is closed. At this time, since the lid body is inclined upward, even if dust remains on the lid body after the dust collection device has finished collecting the dust, the dust is returned to the cleaner side. and is less likely to spill from the tip of the lid.

In the above configuration, the lid body may be configured to be rotatable between a closed position in which the communication path is closed and an open position in which the communication path is opened. The cleaner may further include a biasing member that biases the lid toward the closed position.

According to the above configuration, the lid is urged to the closed position by the urging member, so the lid is less likely to open unnecessarily. Therefore, for example, when the cleaner is not attached to the collection device, the communication passage is prevented from being opened.

In the above configuration, the vacuum cleaner may further include a housing that forms a communication path and houses the dust collection source and the dust storage unit, and a suction nozzle that draws in dust by the suction force of the dust collection source. good. The housing may be attached to the suction nozzle so as to be tiltable rearward from an upright position by a user's operation. The lid body may be provided so as to open and close the communicating path opened in the front wall of the housing.

According to the above configuration, the user can perform cleaning work while pushing out the suction nozzle by tilting the housing backward with respect to the suction nozzle. At this time, due to the rearward tilting of the housing, the communication passage opened in the front wall of the housing is in a state of being opened obliquely upward, and the cover that closes the opening of the communication passage is closed. Gravity acts in the direction to maintain the posture. Therefore, it is difficult to open the lid during cleaning work.

The recovery device according to one aspect of the above-described embodiment is configured so that the above-described vacuum cleaner can be attached. The collection device includes a collection chamber for collecting dust, a dust flow path connected at one end to the collection chamber and communicating with a communication passage in a state where a vacuum cleaner is attached to the collection device, and a collection device. When the vacuum cleaner is attached to the lid, a suction force is applied to the lid so that the lid is in an open position that opens the communicating path, and in the state where the lid is in the open position, the communicating path and the dust flow a suction source configured to draw dust into the collection chamber through the passageway. The lid body is formed so as to enter the dust channel when it is in the open position.

According to the above configuration, when the vacuum cleaner is attached to the collecting device and the suction source applies a suction force to the lid body to open the lid body, the dust flow path of the collecting device is moved to the communicating path. communicate. In this state, the suction force of the suction source can act on the dust in the dust storage section through the dust flow path and communication path. Therefore, the dust in the dust storage space flows into the recovery chamber of the recovery device through the communicating path and the dust flow path. At this time, since the lid body is in a state of entering the dust flow path, the dust can move toward the other end of the dust flow path while being prevented from falling by the lid body.

The vacuum cleaner and collection device of the above-described embodiments are suitable for use in cleaning work.
