The vacuum cleaner 10 of Example 1 is a cyclone vacuum cleaner, dust and air are separated by centrifugal separation, and only the air is exhausted from the exhaust port.

After cleaning, place the vacuum cleaner 10 on the charging base 20 and start charging. Further, the first embodiment is characterized in that the dust collected in the dust collecting portion 112 of the electric vacuum cleaner 10 is transferred to the dust container of the charging base 20 . This configuration will be described below.

FIG. 4 is a partial cross-sectional view taken along the vertical direction of the cleaning system according to the first embodiment of the present invention. The dust collecting portion 112 includes an outer cylinder 1121 forming an outer shell of the dust collecting portion 112, an inner cylinder 1122 accommodated inside the outer cylinder 1121, an umbrella portion 1123 disposed below the inner cylinder 1122, and an umbrella. A convex portion 1124 protruding downward from the portion 1123 and a compression spring 1125 arranged between the inner cylinder 1122 and the convex portion 1124 to urge the umbrella portion 1123 and the convex portion 1124 downward are provided. In Example 1, the umbrella portion 1123, the convex portion 1124, and the compression spring 1125 constitute a dust discharge mechanism.

A filter storage chamber 1126 is formed above the outer cylinder 1121 . A first filter 1127 for filtering dust contained in the air that has passed through the inner cylinder 1122 is provided below the filter storage chamber 1126, and the first filter 1127 is provided above (downstream) the first filter 1127. A second filter 1128 is provided to filter dust contained in the passing air.

The blower 110 is arranged above (on the downstream side of) the filter storage chamber 1126, and the filter storage chamber 1126 and the suction port of the blower 110 communicate with each other. The cleaner main body 11 is provided with an exhaust port 119 for discharging the exhaust air of the blower 110 to the outside.

A lid body 1129 that opens downward is provided below the dust collection section 112 (outer cylinder 1121). The lid 1129 is rotatably supported by the dust collecting section 112 (outer cylinder 1121) by a lid hinge 1129a.

An inlet 1121a communicating with the extension pipe 12 is formed above the outer cylinder 1121, and the inlet 1121a is connected to the outer cylinder 1121 so that the air flowing in from the inlet 1121a swirls in the outer cylinder 1121. is shifted from the central axis 120 of the .

In the electric vacuum cleaner 10 of Embodiment 1, the central axis 12a of the extension pipe 12, the central axis 120 of the outer cylinder 1121, and the central axis 110a of the blower 110 face the same direction.

On the other hand, the charging base 20 includes a cylindrical portion 201 recessed downward from above, a conical portion 202 disposed below the cylindrical portion 201, and a lower surface connecting portion formed below the conical portion 202. A dust receptacle receiving portion 204 is provided which communicates with the conical portion 202 by 203 . In Example 1, the cylindrical portion 201 and the conical portion 202 form the communicating cylindrical portion 200 . The communication tube portion 200 has a circular shape or a D shape when viewed from above. In the case of the D shape, the flat surface is located at the lid hinge 1129a. The lower surface connecting portion 203 is formed in a cylindrical shape and its diameter is formed to be larger than the outer diameter of the umbrella portion 1123, so that the dust collected under the umbrella portion 1123 is sent to the dust container 205 without clogging. In other words, the communicating cylinder part 200 of the first embodiment has a function of allowing the dust collected in the dust collecting part 112 to pass through and sending the dust to the dust container 205 .

A dust container 205 for receiving dust from the dust collection unit 112 is provided inside the dust container storage unit 204 . In addition, the dust container accommodating portion 204 is provided with an openable door 206 that can be opened and closed as indicated by a broken line. A sealing member (not shown) is provided between the dust container accommodating portion 204 and the opening/closing door 206 to make the inside of the dust container accommodating portion 204 an airtight space.

A connection seal member 207 for maintaining airtightness is provided at the connection portion between the dust collecting portion 112 and the charging base 20 . The connection seal member 207 may be provided either on the charging stand 20 side or on the dust collecting section 112 side.

The dust collection part 112 is located directly above the communication tube part 200 when the vacuum cleaner 10 is placed on the charging base 20 . When dust collector 112 and charging base 20 are connected, lid 1129 is unlocked, and lid 1129 opens toward cylindrical portion 201 with lid hinge 1129a as a fulcrum. When the cover 1129 is opened, the dust accumulated in the dust collecting portion 112 drops toward the cylindrical portion 201 due to gravity. Furthermore, in Example 1, the umbrella portion 1123 and the convex portion 1124 slide toward the charging base 20 due to the action of the compression spring 1125 that urges the umbrella portion 1123 and the convex portion 1124 downward. Dust adhering inside and around the portion 1124 is pushed out to the cylindrical portion 201 below.

Furthermore, in Embodiment 1, the blower 110 is driven to discharge the dust collected in the dust collecting section 112 . In a conventional electric vacuum cleaner, a blower for suction is provided on the charging base side so as to suck out the dust collected on the vacuum cleaner side. It is characterized by discharging dust to the charging stand side. Next, the operation of discharging dust to the charging stand will be described with reference to FIGS. 4 and 5. FIG. FIG. 5 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 the first embodiment, automatic cleaning means driving the blower 110 while the vacuum cleaner 10 is placed on the charging stand.

When the cleaning is finished and the vacuum cleaner 10 is placed on the charging base 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 charging base 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 charging base 20 .

Whether or not the vacuum cleaner 10 is placed on the charging base 20 is determined using a mechanical ground sensor (not shown) provided on the suction body 13 in addition to the charging state of the storage battery 114 described above. may 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 FIG. 1, when the vacuum cleaner 10 is placed on the charging stand 20, the suction body 13 is configured to be grounded, so the grounding can be detected by the grounding sensor of the suction body 13. In other words, it can be determined that the vacuum cleaner 10 is placed on the charging base 20 when the storage battery 114 is charged and the ground sensor can determine that the suction member 13 is grounded. According to this, even if the power line 22 and the female connector 23 are detachable from the charging base 20 , it can be reliably determined that the vacuum cleaner 10 is placed on the charging base 20 .

The control unit 118 detects the remaining amount of the storage battery 114 and determines whether or not the remaining amount of the 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 start mode of the dust collection unit 112 after the vacuum cleaner 10 is placed on the charging base 20. It is determined whether or not a predetermined time has elapsed since the transition (step S506). This predetermined time is the time from when the vacuum cleaner 10 is placed on the charging base 20 until the lid body 1129 is opened and the dust falls on the cylindrical portion 201, and when the vacuum cleaner 10 is placed on the charging base 20 and is in use. This time is set with the intention of the time required for the person to leave the charging base 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 charging base 20 (No in step S506), step S504 Repeat the actions from

In step S506, when a predetermined time has passed since the vacuum cleaner 10 was placed on the charging stand 20 (Yes in step S506), the control unit 118 notifies that the dust collection unit 112 is automatically cleaning. The notification mode is executed (step S507). In the notification mode of Example 1, 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, the control unit 118 drives the blower 110 (step S508) and automatically cleans the dust collecting unit 112.

Here, referring back to FIG. 4, the operation of automatic cleaning of the dust collecting section 112 will be described. 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 cylindrical portion 201 and the conical portion 202 due to the swirling flow, and is finally accommodated in the dust container 205 located below the communicating cylindrical portion 200 .

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.

Returning to FIG. 5, the control unit 118 determines whether or not a predetermined period of time has passed since the blower 110 was driven (step S509). Stop (step S510). In step S509, if the predetermined time has not elapsed (No in step S509), the control unit 118 repeats the operations from step S507.

After the blower 510 stops, the control unit 118 cancels the notification mode for notifying that automatic cleaning is in progress (step S511). In Example 1, the

display units

1153a and 1153b installed in the operation switch unit 115 of the vacuum cleaner 10 are turned off (see FIGS. 2A and 2B).

The automatic cleaning of the dust collection unit 112 is completed through the above steps. In the above-described embodiment, when the electric vacuum cleaner 10 is placed on the charging base 20, the cleaning of the dust collecting portion 112 is automatically performed, but it is also possible to perform the cleaning manually according to the user's will. Manual mode will be described with reference to FIG. FIG. 6 is an operational flow chart of an automatic cleaning mode of the dust collector by manual operation according to an embodiment of the present invention. In FIG. 6, the operation in which the dust collecting portion is cleaned even by manual operation is referred to as an automatic cleaning mode. Manual operation is to drive the fan 110 according to the user's intention.

When the cleaning is finished and the vacuum cleaner 10 is placed on the charging base 20, the control unit 118 starts the manual cleaning mode of the dust collection unit 112 (step S601).

Next, the control unit 118 executes charge detection control for the storage battery 114 (step S602). Control unit 118 determines whether or not the manual start button (automatic cleaning control button 1151b, 24) of dust collection unit 112 has been pressed (step S603). In Example 1, manual cleaning is started by pressing and holding the "standard" operation control button 1151 of the operation switch unit 115 for three seconds.

When the manual start button (automatic

cleaning control buttons

1151b and 1151b, 24) of the dust collection unit 112 is pressed (Yes in step S603), the control unit 118 detects whether or not the storage battery 114 is being charged. (step S604).

If the manual start button (automatic cleaning control buttons 1151b, 24) of the dust collection unit 112 is not pressed (No in step S603), the operations from step S602 are repeated.

When the control unit 118 determines that the storage battery 114 is being charged (Yes in step S604), the storage battery 114 is continuously charged (step S605). When the control unit 118 determines that the storage battery 114 has not been charged (No in step S604), it notifies that the charging cannot be started (step S606), and repeats the operation from step S602. The means for notifying that charging cannot be started is, for example, blinking the charging mark (battery mark) in FIG.

The control unit 118 determines whether the vacuum cleaner 10 is placed on the charging base 20 based on whether the storage battery 114 is being charged in step S604. That is, if the storage battery 114 is being charged, it is determined that the vacuum cleaner 10 is placed on the charging base 20 .

The control unit 118 detects the remaining amount of the storage battery 114 and determines whether or not the remaining amount of the storage battery 114 is equal to or greater than a predetermined amount (step S607). If the remaining amount of the storage battery 114 is equal to or greater than the predetermined amount (Yes in step S607), the control unit 118 starts the manual cleaning start mode of the dust collection unit 112 after the vacuum cleaner 10 is placed on the charging stand 20. It is determined whether or not a predetermined time has elapsed since the transition (step S608). This predetermined time is the time from when the vacuum cleaner 10 is placed on the charging base 20 until the lid body 1129 is opened and the dust falls on the cylindrical portion 201, and when the vacuum cleaner 10 is placed on the charging base 20 and is in use. This time is set with the intention of the time required for the person to leave the charging base 20 .

When the remaining amount of the storage battery 114 is less than the predetermined amount (No in step S607) and when the predetermined time has not passed since the vacuum cleaner 10 was placed on the charging stand 20 (No in step S608), the preparation mode is entered. (step S609), and then the operation from step S605 is repeated. In the preparation mode, for example, the

display units

1153a and 1153b blink (see FIGS. 2A and 2B).

In step S608, when a predetermined time has passed since the vacuum cleaner 10 was placed on the charging base 20 (Yes in step S608), the control unit 118 notifies that the dust collection unit 112 is cleaning. mode is executed (step S610). In the notification mode of Example 1, the

display units

After executing the notification mode, the control unit 118 drives the blower 110 (step S611) and cleans the dust collecting unit 112.

The operation of cleaning the dust collecting part 112 is the same as the automatic cleaning described with reference to FIG. 4, so the description is omitted.

The control unit 118 determines whether or not a predetermined period of time has elapsed since the fan 110 was driven (step S612), and if the predetermined period of time has elapsed (Yes in step S612), stops the operation of the fan 110 (step S613). ). In step S612, if the predetermined time has not elapsed (No in step S612), the control unit 118 repeats the operations from step S610.

After the blower 510 stops, the control unit 118 cancels the notification mode for notifying that the dust collection unit 112 is cleaning (step S614). In Example 1, the

display units

As described above, according to the first embodiment, the dust in the dust collecting portion 112 of the vacuum cleaner 10 is transferred to the charging stand 20 side by utilizing the swirling flow, so that the dust is collected on the charging stand 20 side. Dust can be transferred to the charging base 20 regardless of the dust state. Further, according to the first embodiment, the dust collecting portion 112 and the communication tube portion 200 are communicated with each other to increase the number of swirling air, so that fine dust in the dust collecting portion 112 can be collected. Further, according to the first embodiment, the charging stand 20 side does not require a blower for sucking dust from the dust collecting portion 112 of the vacuum cleaner 10, so that the manufacturing cost can be reduced.

Next, Example 2 will be described with reference to FIG. FIG. 7 is a partial cross-sectional view of the cleaning system according to the second embodiment of the present invention cut along the vertical direction. The same reference numerals are assigned to the same configurations as those of the first embodiment, and detailed description thereof will be omitted.

The second embodiment differs from the first embodiment in the configuration of the charging base 20 .

In the first embodiment, the dust container housing portion 204 is provided below the conical portion 202, but in the second embodiment, the dust container 205 is eliminated and the communication tube portion 200 also serves as the dust container.

Dust falling from the dust collection part 112 passes through the cylindrical part 201 forming the communication cylinder part 200 and accumulates in the conical part 202 .

The communication cylinder part 200 can be detached from the charging base 20 at the detachable part 208, and by removing the communication cylinder part 200 from the charging base 20, the dust accumulated in the communication cylinder part 200 can be discarded.

When disposing of the dust accumulated in the communication cylinder part 200, a bag may be set inside the communication cylinder part 200, the dust may be contained in the bag, and the dust contained in the bag may be disposed of.

According to the second embodiment, in addition to the effects of the first embodiment, the communication cylinder part 200 also serves as a dust container, so the configuration of the charging base 20 can be simplified.

Next, Example 3 will be described with reference to FIG. FIG. 8 is a partial cross-sectional view of the cleaning system according to the third embodiment of the present invention cut along the vertical direction. The same reference numerals are assigned to the same configurations as those of the first embodiment, and detailed description thereof will be omitted.

The third embodiment differs from the first embodiment in the configuration of the charging base 20 .

In Example 1, the dust container housing portion 204 was provided below the conical portion 202, but in Example 3, the dust container 205 and the conical portion 202 were eliminated, and the cylindrical portion 201 alone constituted the communicating cylindrical portion 200, The communication cylinder part 200 also serves as a dust container.

central axes

12b and 110b coincide with the central axis 120 of the outer cylinder 1121. are orthogonal. Note that the extension pipe 12 may be removed when it is placed on the charging base 20 .

The configuration of the charging base 20 is the same as that of the first embodiment.

When the dust collecting part 112 and the charging base 20 are connected, the lid body 1129 is unlocked, and the lid body 1129 opens toward the cylindrical part 201 with the lid body hinge 1129a as a fulcrum. When the cover 1129 is opened, the dust accumulated in the dust collecting portion 112 drops toward the cylindrical portion 201 due to gravity. Since the umbrella portion 1123 and the convex portion 1124 are provided with a compression spring 1125 that urges them downward, the action of the compression spring 1125 pushes the dust adhering around the umbrella portion 1123 and the convex portion 1124 downward. is extruded into the cylindrical portion 201 of the

Furthermore, in the fourth embodiment, as in the first embodiment, the blower 110 is driven to discharge the dust collected in the dust collecting section 112. Next, the operation of discharging dust to the charging base side will be described.

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 . Dust in the dust collecting portion 112 moves to the cylindrical portion 201 and the conical portion 202 due to the swirling flow, and is finally accommodated in the dust container 205 . 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 passes through the provided mesh filter and reaches the cyclone section 130 .

In the cyclone section 130, the air that has been centrifuged by the outer cylinder 1121 and passed through the inner cylinder 1122 is divided into a plurality of streams, and then the dust contained in the air is centrifuged at a plurality of locations. Furthermore, the air subjected to centrifugal separation is passed through the filter 131 to filter dust contained in the air. The air that has passed through the filter 131 is sucked by the blower 110 and discharged to the outside through the exhaust port 119 . In this manner, automatic cleaning of the dust collecting section 112 is performed.

According to the fourth embodiment, even if the form of the vacuum cleaner 10A is changed, the same effects as those of the first embodiment can be obtained.
