It has a communicating space 215 that connects with the dust container accommodating portion 214, and a leg portion 216 that contacts the floor surface.

The dust collection portion 210 is formed to extend rearward from the communication tube portion 200 . That is, the dust collecting portion 210 is formed longer than the communication tube portion 200 in the front-rear direction. As a result, the internal space of the dust collecting portion 210 is formed wider than the internal space of the communication tube portion 200 .

The dust inflow portion 211 is provided with an inclined portion 220 having an inclined surface that slopes downward from the outer periphery of the dust collecting portion 210 toward the inner periphery thereof. One end of the inclined portion 220 is fixed to the inner wall (inner peripheral surface) of the dust collecting portion 210 , and the inside of the dust collecting portion 210 is divided into the dust inflow portion 211 and the communicating space portion 215 . A lower end portion 220 a (the other end) of the inclined portion 220 does not contact the inner wall of the dust collecting portion 210 , and a communication opening 217 is formed between the lower end portion 220 a and the inner wall of the dust collecting portion 210 . The opening area of the communicating opening 217 is formed to be larger than the opening area (diameter) of the communicating tubular portion 200 . By configuring in this manner, the communication opening 217 is prevented from being clogged with dust that has passed through the communication tube portion 200 .

In addition, the inclined portion 220 is arranged so as to be positioned on the downward extension of the tubular communication portion 200 . That is, the slopes of the communication tube portion 200 and the inclined portion 220 are arranged so as to face each other in the vertical direction. After colliding with the inclined portion 220 , the dust falling from the communicating tube portion 200 moves along the inclined portion and passes through the communicating opening 217 to be guided to the dust container 213 . The dust container 213 is open at the top, and the inclined portion 220 is inclined downward toward the opening of the dust container 213 . In order to guide dust smoothly, the inclination angle θ of the inclined portion 220 is preferably 40 degrees or more and less than 90 degrees with respect to the floor surface. In this embodiment, the inclination angle θ is set to 40 degrees.

The dust container 213 can be pulled out from the front of the dust collector 210 and removed as indicated by arrows in FIGS. 5 to 7 . FIG. 8 is a top perspective view of the dust container according to the embodiment of the present invention. The dust container 213 is composed of a container body 2131 for collecting dust and a dust container cover 2132 attached in the removal direction (front) of the container body 2131 . The dust container lid 2132 is attached so as to cover a part (front) of the outer periphery of the container main body 2131. When the dust container 213 is attached to the dust collecting portion 210, the outer peripheral surface of the dust container lid 2132 is used for dust collection. It becomes flush with the portion 210 .

At the rear of the container main body 2131, a container inclined portion 2133 is formed that slopes downward from the rear of the container main body 2131 toward the front. A dust container transparent window 2134 is formed on the side surface of the container body 2131 , and the amount of dust contained in the container body 2131 can be confirmed through the dust container transparent window 2134 . A dust collecting portion transparent window 2101 (transparent portion) is formed in the dust collecting portion 210 so as to overlap with the dust container transparent window 2134 . The amount of dust contained in the container main body 2131 can be confirmed from the bottom side of the dust collection section 210 through the dust collection section transparent window 2101 and the dust container transparent window 2134 . Note that the container main body 2131 may be entirely made of a transparent member. In this case, the dust contained in the dust container 213 can be confirmed from the outside through the transparent container main body 2131 and the dust collecting portion transparent window 2101 (transparent portion).

Further, the dust container transparent window 2134 is located on the front side (the dust container cover 2132 side) of the container inclined portion 2133 . The dust falling from the inclined portion 220 collides with the container inclined portion 2133, and upon collision with the container inclined portion 2133, the dust is guided forward along the container inclined portion 2133 (toward the dust container lid 2132). Since the dust container transparent window 2134 is positioned in front of the end of the inclined container portion 2133, the amount of dust guided forward along the container inclined portion 2133 can be confirmed through the dust container transparent window 2134. can do.

When dust accumulates in the dust container 213, the dust container 213 is pulled out from the dust collection unit 210 and the accumulated dust is discarded. Since the dust container 213 can be taken out from the dust collection unit 210, it is necessary to prevent dust from leaking out from the portion where the dust container 213 and the dust collection unit 210 are in contact with each other. Therefore, in this embodiment, the dust container cover 2132 is provided with seals 2135a and 2135b in order to maintain airtightness between the dust container 213 and the outside. The sealing body 2135a is located on the top of the dust container lid 2132, and the sealing body 2135b is provided at the outer peripheral edge of the dust container lid 2132. As shown in FIG. Note that the sealing body 2135 may be provided on the dust collecting section 210 side. The sealing body 2135 is composed of an elastic body such as rubber or sponge.

As shown in FIG. 4, the connecting portion between the dust collecting portion 112 and the stand 20 is provided with a connection sealing member 207 for maintaining airtightness. The connection seal member 207 may be provided either on the stand 20 side or the dust collecting section 112 side.

The dust collection part 112 is positioned directly above the communication tube part 200 when the vacuum cleaner 10 is placed on the stand 20 . When the dust collector 112 and the stand 20 are connected, the lid 1129 is unlocked, and the lid 1129 opens toward the communication cylinder 200 with the lid hinge 1129a as a fulcrum. When the lid body 1129 is opened, the dust collected in the dust collecting portion 112 falls to the communicating tube portion 200 side due to gravity. Furthermore, in this embodiment, the umbrella portion 1123 and the convex portion 1124 slide toward the stand 20 due to the action of the compression spring 1125 that urges the umbrella portion 1123 and the convex portion 1124 downward. The dust adhering to the inside and the periphery of the is pushed out to the communicating tube portion 200 below.

Furthermore, in this embodiment, the blower 110 is driven to discharge the dust collected in the dust collecting section 112 . In conventional vacuum cleaners, a suction blower is provided on the stand side to suck out the dust collected on the vacuum cleaner side, but in this embodiment, the vacuum cleaner side blower is used. , dust is discharged to the side of the stand. Next, the operation of discharging dust to the stand side will be described with reference to FIGS. 4 to 10. FIG. FIG. 10 is an operational flow chart of an automatic cleaning mode of the dust collector by automatic operation according to an embodiment of the present invention. In this embodiment, automatic cleaning means driving the blower 110 while the vacuum cleaner 10 is placed on a stand.

When the cleaning is finished and the electric vacuum cleaner 10 is placed on the stand 20, the control unit 118 starts the automatic cleaning mode of the dust collection unit 112 (step S501).

Next, the control unit 118 executes charge detection control for the storage battery 114 (step S502), and detects whether or not the storage battery 114 is being charged (step S503). When the control unit 118 determines that the storage battery 114 is being charged (Yes in step S503), the storage battery 114 is continuously charged (step S504). If control unit 118 determines that storage battery 114 has not been charged (No in step S503), it repeats the operations from step S502. Control unit 118 determines whether vacuum cleaner 10 is placed on stand 20 based on whether storage battery 114 is being charged in step S503. That is, if at least storage battery 114 is being charged, it is determined that vacuum cleaner 10 is placed on stand 20 .

Whether or not the vacuum cleaner 10 is placed on the stand 20 is determined using a mechanical ground sensor (not shown) provided on the mouthpiece 13 together with the state of charge of the storage battery 114 described above. good too. The ground sensor is a detection means that prevents a rotating brush (not shown) provided on the suction body 13 from being driven in a state of being separated from the floor. As shown in FIGS. 1A and 1B, when the vacuum cleaner 10 is placed on the stand 20, the suction body 13 is grounded, so the grounding sensor of the suction body 13 detects grounding. can. In other words, it can be determined that the vacuum cleaner 10 is placed on the stand 20 when the storage battery 114 is charged and the ground sensor can determine that the suction member 13 is grounded. Accordingly, even when the power line 22 and the female connector 23 are detachable from the stand 20 , it can be reliably determined that the vacuum cleaner 10 is placed on the stand 20 .

Control unit 118 detects the remaining amount of storage battery 114 and determines whether the remaining amount of storage battery 114 is equal to or greater than a predetermined amount (step S505). If the remaining amount of the storage battery 114 is equal to or greater than the predetermined amount (Yes in step S505), the control unit 118 starts the automatic cleaning of the dust collection unit 112 after the vacuum cleaner 10 is placed on the stand 20 (shifts to the automatic cleaning start mode). ), it is determined whether or not a predetermined time has elapsed (step S506). This predetermined time is the time from when the vacuum cleaner 10 is placed on the stand 20 until the lid body 1129 is opened and the dust falls into the communicating tube portion 200, and when the vacuum cleaner 10 is placed on the stand 20 and the user This is the time set with the intention of the time required for the to leave the stand 20 .

When the remaining amount of the storage battery 114 is less than the predetermined amount (No in step S505) and when the predetermined time has not passed since the vacuum cleaner 10 was placed on the stand 20 (No in step S506), the process starts from step S504. repeat the operation.

In step S506, when a predetermined time has passed since the vacuum cleaner 10 was placed on the stand 20 (Yes in step S506), the control unit 118 notifies that the dust collection unit 112 is automatically cleaning. mode is executed (step S507). In the notification mode of this embodiment, the display units 1153a and 1153b installed in the operation switch unit 115 of the vacuum cleaner 10 are turned on (see FIGS. 2A and 2B).

After executing the notification mode, control unit 118 drives blower 110 (step S508) to automatically clean dust collecting unit 112 .

Here, the automatic cleaning operation of the dust collecting section 112 will be described with reference back to FIGS. 4 and 5. FIG. When the blower 110 is driven, air is sucked through the suction body 13 and the extension pipe 12, and the sucked air flows into the outer cylinder 1121 through the inlet 1121a. The air that has flowed into the outer cylinder 1121 becomes a swirling flow, and along the inner wall of the outer cylinder 1121 , the air flows downward, that is, from the dust collecting portion 112 toward the communicating cylinder portion 200 . In other words, the length of the dust collecting portion 112 in the swirling flow axis direction is extended by the length of the communication tube portion 200 . According to this, compared to the case where the air swirls only in the dust collecting part 112, the distance that the air swirls as a swirling flow, that is, the number of times of swirling increases. Even if it is small, it becomes easier to reach the inner wall surface of the dust collecting portion 112 or the communication tube portion 200 . The dust in the dust collecting portion 112 moves to the communicating tube portion 200 by the swirling flow, and is finally collected in the dust collecting portion 210 positioned below the communicating tube portion 200 .

When the swirling flow flows into the dust collection section 210 from the communicating tube portion 200, the space is enlarged, so the speed of the swirling flow is reduced. Along with this, the speed of dust contained in the swirling flow also decreases. The dust falls downward along the inclined portion 220 and passes through the communication opening 217 to be stored in the dust container 213 .

Part of the swirling flow enters the communication space 215 through the communication opening 217 and tries to stir up dust. In this embodiment, the dust stirred up by the swirling flow collides with the lower surface (rear surface) of the inclined portion 220 and falls downward to be accommodated in the dust container 213 .

According to this embodiment, since the dust collecting portion 210 is provided with the inclined portion 220, it is possible to suppress the dust collected in the dust collecting portion 210 from being stirred up.

The air swirling around the outer cylinder 1121 changes its direction, generates a flow from the communicating cylinder portion 200 toward the dust collecting portion 112, passes through the mesh filter formed in the umbrella portion 1123, and further reaches the outer circumference of the inner cylinder 1122. It reaches the filter storage chamber 1126 through the provided mesh filter. The air that has flowed into the filter storage chamber 1126 passes through the first filter 1127 and the second filter 1128, is sucked by the blower 110, and is exhausted to the outside through the exhaust port 119. In this manner, automatic cleaning of the dust collecting section 112 is performed.

In order to prevent dust from blowing over, it is preferable to prevent the dust container 213 from being pulled out of the dust collection unit 210 during automatic cleaning. FIG. 9 is an enlarged perspective view showing an enlarged part of the vacuum cleaner placed on the stand according to the embodiment of the present invention. In this embodiment, automatic operation is performed in a state in which the vacuum cleaner 10 is placed on the stand 20 and the suction body 13 is configured to be grounded to the stand 20 . In this state, as shown in FIGS. 1A, 1B, and 9, the suction member 13 and the extension pipe 12 are positioned in front of the dust container 213 (in the pull-out direction). The dust container 213 is pressed, and the withdrawal of the dust container 213 can be suppressed.

In this embodiment, the dust container 213 is pulled out in the front direction, but the removal direction (pull-out direction) of the dust container 213 may be left, right, or rear. If the removal direction (pull-out direction) is any one of the left side, the right side, and the rear side, there is a possibility that the dust container 213 will be pulled out of the dust collecting section 210 during automatic cleaning. In order to solve this problem, for example, the dust collector 210 is provided with locking means. The locking means are constructed as follows. The dust collecting unit 210 is provided with a pin that can move from the dust collecting unit 210 side toward the dust container 213 side, and an actuator that drives the pin. The dust container 213 is provided with a receiving portion into which a pin is inserted and received. Then, during execution of automatic cleaning, the actuator is operated to project the pin toward the dust container 213 side. A pin is inserted into the receiving portion on the dust container 213 side. With this configuration, the movement of the dust container 213 is restricted by the pin during automatic cleaning, so that it is possible to prevent dust from blowing out when the dust container 213 is pulled out.

Further, when the dust collection unit 210 is not equipped with a lock means, the dust container 213 can be prevented from being pulled out by utilizing the lighting state of the display units 1153a and 1153b installed in the operation switch unit 115 of the vacuum cleaner 10. good. For example, the dust collection unit 210 or the dust container 213 has a warning about the removal operation of the dust container 213, such as "Do not pull out the dust container 213 while the display units 1153a and 1153b are lit (while the vacuum cleaner is in operation)."
