FIG. 4 is a cross-sectional view of the vacuum cleaner 10 according to the first embodiment of the present invention taken along the vertical direction. FIG. 4 shows the air flow when the vacuum cleaner 10 is used. In FIG. 4, the extension pipe 12 and the suction body 13 connected to the vacuum cleaner 10 are omitted.

The dust collecting section 112 is detachably attached to the cleaner body 11. A main body passage 1101 communicating with the dust collecting section 112 is formed in the cleaner main body 11 connected to the extension tube 12 . An outlet of the main body passage 1101 is connected to an inlet 1121 of the dust collecting section 112.

The dust collecting section 112 is equipped with a dust collecting filter 1122 (first dust collecting filter) that filters the air containing dust flowing in from the inlet 1121, and the dust 1124 is collected in the dust storage space 1123 of the dust collecting section 112. be dusted. A dust collection lid 1125 for discarding the dust 1124 collected in the dust storage space 1123 is provided below the dust collection unit 112 (on the side opposite to the electric blower) so as to be openable and closable.

Additionally, a flow path switching section 130 is provided above the dust collecting section (on the electric blower side or downstream side). The flow path switching section 130 is located between the dust collecting section 112 and the electric blower 110. A dust collecting section communication opening 1126 is formed between the dust collecting section 112 and the flow path switching section 130, which communicates the dust collecting section 112 and the flow path switching section 130.

An electric blower side opening 131 that communicates with the inlet of the electric blower 110 is formed on the electric blower side (downstream side) of the flow path switching section 130. Further, the flow path switching section 130 is formed with a second flow path communication opening 132 that communicates with a second flow path of the mounting table 20, which will be described later.

Furthermore, the flow path switching section 130 is equipped with a switching valve 133 that opens and closes the dust collection section communication opening 1126 and the second flow path communication opening 132. This switching valve 133 operates so as to open the other when either the dust collector communication opening 1126 or the second flow path communication opening 132 is closed. In this embodiment, the switching valve 133 is not limited to a valve body, but may be any switching mechanism that can switch the flow path.

When cleaning the floor surface, the vacuum cleaner 10 is removed from the mounting table 20. At this time, the switching valve 133 operates to open the dust collector communication opening 1126 and close the second flow path communication opening 132.

When the operation control button 1151 of the operation switch section 115 is pressed, the electric blower 110 starts operating and generates suction force. A suction body 13 is in contact with the floor surface, and dust on the floor surface is sucked together with air. Air and dust sucked from the suction body 13 flow into the dust collecting section 112 via the extension pipe 12 and the inlet 1121. The air and dust 1124 that have flowed into the dust collection section 112 are filtered by the dust collection filter 1122, the air passes through the dust collection filter 1122, and the dust 1124 is collected in the dust storage space 1123. The air that has passed through the dust filter 1122 passes through the flow path switching section 130, is sucked into the electric blower 110 through the electric blower side opening 131, and is exhausted outside the vacuum cleaner body.

The vacuum cleaner main body 11 is also provided with a male connector 116 that connects to the female connector 23 of the mounting table 20.

Next, the operation after cleaning is finished will be explained. FIG. 5 is a partial cross-sectional view of the main part of the cleaning system according to the first embodiment of the present invention, cut along the vertical direction. After the cleaning is completed, the vacuum cleaner 10 is placed on the mounting table 20 as shown in FIG. 5, and charging is started. The first embodiment is characterized in that the dust collected in the dust collection section 112 of the vacuum cleaner 10 is transferred to the dust collection container 203 of the mounting table 20. That is, the mounting table 20 has a function of collecting the dust collected in the dust collecting section 112. This configuration will be explained below.

The mounting table 20 includes a first flow path 201 located below the dust collecting section 112 and extending downward when the vacuum cleaner 10 is placed on the mounting table 20, and a first flow path 201 adjacent to the first flow path 201. However, a second flow path 202 extending upward is provided. The first flow path 201 is arranged at a position on the downward extension of the dust collection section 112, and the second flow path 202 is arranged at a position shifted from the downward extension of the dust collection section 112. A dust collection container 203 is provided at the bottom of the first flow path 201 to receive dust falling from the dust collection section 112. The dust collection container 203 is open at the top and is provided to be detachable from the mounting table 20.

Furthermore, a dust filter 204 (second dust filter) as a dust collecting means is provided in the flow path composed of the first flow path 201 and the second flow path 202. In the first embodiment, a dust filter 204 is provided between the first flow path 201 and the second flow path 202.

The dust collecting container 203 may be configured to have air permeability, or a paper pack filter having a similar effect may be used. The paper pack filter is made removable from the mounting table 20, and when the paper pack filter is full of collected dust, dust collection performance can be restored by replacing it with a new paper pack filter.

One side of the first flow path 201 communicates with the dust collection section 112, and the other side communicates with one of the second flow paths 202 via the dust collection filter 204.

One side of the second flow path 202 communicates with the other of the first flow path 201, and the other side communicates with the flow path switching section 130 via the second flow path communication opening 132.

The dust collection unit 112 is located directly above the first flow path 201 with the vacuum cleaner 10 placed on the mounting table 20. When the dust collection unit 112 and the mounting table 20 are connected, the dust collection lid 1125 is unlocked, and the dust collection lid 1125 opens toward the first flow path 201 using the hinge as a fulcrum. When the dust collection lid 1125 opens, the dust accumulated in the dust storage space 1123 of the dust collection section 112 falls toward the first flow path 201 due to gravity.

In addition, in the flow path switching section 130, a part of the flow path switching section 130 contacts the mounting table 20 and the switching valve 133 rotates, opening the second flow path communication opening 132 and opening the dust collection section communication opening 1126. It acts like closing.

When the dust collection lid 1125 is opened, the dust accumulated in the dust storage space 1123 of the dust collection section 112 falls to the first flow path 201 side due to gravity, but some of the dust is transferred to the dust collection filter 1122 and the dust collection section 112. It may be attached to walls etc.

Embodiment 1 has a function of driving the electric blower 110 and discharging the dust remaining in the dust collecting section 112. Next, the operation of discharging the dust remaining in the dust collecting section 112 to the mounting table side will be explained using FIGS. 5 and 6. FIG. 6 is an operation flowchart of the automatic cleaning mode of the dust collecting section 112 by automatic operation according to the first embodiment of the present invention. In the first embodiment, automatic cleaning means driving the electric blower 110 while the vacuum cleaner 10 is placed on the mounting table.

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

Next, the control unit 118 executes control to detect charging of the storage battery 114 (step S602), and detects whether charging of the storage battery 114 is being performed (step S603). If the control unit 118 determines that the storage battery 114 is being charged (Yes in step S603), it continues charging the storage battery 114 (step S604). If the control unit 118 determines that the storage battery 114 is not being charged (No in step S603), it repeats the operations from step S602. The control unit 118 determines whether the vacuum cleaner 10 is placed on the mounting table 20 based on whether the storage battery 114 is being charged in step S603. That is, if at least the storage battery 114 is being charged, it is determined that the vacuum cleaner 10 is placed on the mounting table 20.

Whether or not the vacuum cleaner 10 is placed on the mounting table 20 is determined by 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. It's okay. The ground sensor is a detection means that prevents a rotating brush (not shown) provided on the suction body 13 from being driven away from the floor. As shown in FIG. 1, when the vacuum cleaner 10 is placed on the mounting table 20, the suction body 13 is configured to be grounded, so that the ground sensor of the suction body 13 can detect grounding. In other words, when the storage battery 114 is charged and the ground sensor determines that the suction body 13 is grounded, it can be determined that the vacuum cleaner 10 is placed on the mounting table 20. According to this, even if the power line 22 and the female connector 23 are removable from the mounting table 20, it can be reliably determined that the vacuum cleaner 10 is placed on the mounting table 20.

The control unit 118 detects the remaining amount of the storage battery 114 and determines whether the remaining amount of the storage battery 114 is greater than or equal to a predetermined amount (step S605). If the remaining amount of the storage battery 114 is equal to or higher than the predetermined amount (Yes in step S605), the control unit 118 sets the automatic cleaning of the dust collecting unit 112 to the start mode after the vacuum cleaner 10 is placed on the mounting table 20. It is determined whether a predetermined period of time has passed since the transition (step S606). This predetermined time is the time period from when the vacuum cleaner 10 is placed on the mounting table 20 until the dust collection lid 1125 opens and the dust 1124 falls into the dust collection container 203. This time is set with the intention of taking the time required for the user to leave the mounting table 20.

If the remaining capacity of the storage battery 114 is less than the predetermined amount (No in step S605) and if the predetermined time has not elapsed since the vacuum cleaner 10 was placed on the mounting table 20 (No in step S606), the process proceeds to step S604. Repeat the operations from.

In step S606, if a predetermined period of time has elapsed since the vacuum cleaner 10 was placed on the mounting table 20 (Yes in step S606), the control unit 118 notifies that the dust collection unit 112 is automatically cleaning. The notification mode is executed (step S607). In the notification mode of the first embodiment, the display sections 1153a and 1153b installed on the operation switch section 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 electric blower 110 (step S608) and executes automatic cleaning of the dust collection unit 112.

Now, referring back to FIG. 5, the automatic cleaning operation of the dust collecting section 112 will be explained. During automatic cleaning of the dust collecting section 112, air flows as shown by the arrow. When the electric blower 110 is driven, air is sucked in through the mouthpiece 13, the extension tube 12, and the main body passage 1101, and the sucked air flows into the dust collecting section 112 from the inlet 1121.

The air flowing into the dust collecting section 112 flows through the surface of the dust collecting filter 1122 and the inner surface of the dust collecting section 112, peels off the dust 1124 attached to the dust collecting filter 1122 and the inner surface of the dust collecting section 112, and collects the dust 1124 together with the dust 1124 in the first It flows into the flow path 201.

The dust 1124 separated from the dust filter 1122 and the inner surface of the dust collection section 112 passes through the first flow path 201, the dust collection container 203, and the dust collection filter 204 together with air, and only air flows into the second flow path 202. .

The air that has flowed into the second flow path 202 rises within the second flow path 202 and flows into the flow path switching section 130 from the second flow path communication opening 132. The air that has flowed into the flow path switching section 130 is sucked into the electric blower 110 through the electric blower side opening 131 and is exhausted outside the vacuum cleaner body. In this way, automatic cleaning of the dust collecting section 112 is performed.

Returning to FIG. 6, the control unit 118 determines whether a predetermined time has elapsed since the electric blower 110 was driven (step S609), and if the predetermined time has elapsed (Yes in step S609), the electric blower 110 The operation is stopped (step S610). In step S609, if the predetermined time has not elapsed (No in step S609), the control unit 118 repeats the operations from step S607.

After the electric blower 110 stops, the control unit 118 cancels the notification mode that notifies that automatic cleaning is in progress (step S611). In the first embodiment, the display sections 1153a and 1153b installed on the operation switch section 115 of the vacuum cleaner 10 are turned off (see FIGS. 2A and 2B).

Through the above steps, automatic cleaning of the dust collecting section 112 is completed. In the embodiment described above, when the vacuum cleaner 10 is placed on the mounting table 20, the dust collection section 112 is automatically cleaned, but it is also possible to clean the dust collection part 112 manually according to the user's intention. The manual mode will be explained using FIG. 7. FIG. 7 is an operation flowchart of the automatic cleaning mode of the dust collecting section 112 by manual operation according to the first embodiment of the present invention. In FIG. 7, an operation in which the dust collecting section 112 is cleaned even if it is a manual operation is referred to as an automatic cleaning mode. Manual operation is to drive the electric blower 110 according to the user's intention.

When the cleaning is finished and the vacuum cleaner 10 is placed on the mounting table 20, the control unit 118 starts the manual cleaning mode of the dust collecting unit 112 (step S701).

Next, the control unit 118 executes detection control for charging the storage battery 114 (step S702). The control unit 118 determines whether the manual start button (automatic cleaning control button 1151b: see FIG. 2B) of the dust collection unit 112 has been pressed (step S703). In the first embodiment, manual cleaning is started by pressing and holding "Standard" of the operation control button 1151 of the operation switch section 115 for 3 seconds.

If the manual cleaning start button (automatic cleaning control button 1151b) is pressed (Yes in step S703), the control unit 118 detects whether or not the storage battery 114 is being charged (step S704).

If the manual start button (automatic cleaning control button 1151b) is not pressed (No in step S703), the operations from step S702 are repeated.

If the control unit 118 determines that the storage battery 114 is being charged (Yes in step S704), it continues to charge the storage battery 114 (step S705). If the control unit 118 determines that charging of the storage battery 114 is not being performed (No in step S704), it notifies that charging cannot be started (step S706), and repeats the operations from step S702. The means for notifying that charging cannot be started, for example, causes the charging mark (battery mark) in FIG. 2 to blink.

The control unit 118 determines whether the vacuum cleaner 10 is placed on the mounting table 20 based on whether the storage battery 114 is being charged in step S704. That is, if the storage battery 114 is being charged, it is determined that the vacuum cleaner 10 is placed on the mounting table 20.

The control unit 118 detects the remaining amount of the storage battery 114 and determines whether the remaining amount of the storage battery 114 is equal to or greater than a predetermined amount (step S707). If the remaining amount of the storage battery 114 is equal to or higher than the predetermined amount (Yes in step S707), the control unit 118 starts the manual cleaning of the dust collecting unit 112 after the vacuum cleaner 10 is placed on the mounting table 20. It is determined whether a predetermined period of time has passed since the transition (step S708). This predetermined time is the time period from when the vacuum cleaner 10 is placed on the mounting table 20 until the dust collection lid 1125 opens and the dust falls into the dust collection container 203. This time is set with the intention of taking the time required for the user to move away from the mounting table 20.

If the remaining capacity of the storage battery 114 is less than the predetermined amount (No in step S707) and if the predetermined time has not passed since the vacuum cleaner 10 was placed on the mounting table 20 (No in step S708), the preparation mode is activated. (step S709), and then repeats the operations from step S705. In the preparation mode, for example, the display sections 1153a and 1153b blink (see FIGS. 2A and 2B).

In step S708, if a predetermined period of time has elapsed since the vacuum cleaner 10 was placed on the mounting table 20 (Yes in step S708), the control unit 118 sends an alert notifying that the dust collecting unit 112 is being cleaned. mode is executed (step S710). In the notification mode of the first embodiment, the display sections 1153a and 1153b installed on the operation switch section 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 electric blower 110 (step S711) and executes cleaning of the dust collection unit 112.

The operation of cleaning the dust collecting section 112 is the same as the automatic cleaning explained using FIG. 5, so the explanation will be omitted.

The control unit 118 determines whether a predetermined time has elapsed since the electric blower 110 was driven (step S712), and if the predetermined time has elapsed (Yes in step S712), the control unit 118 stops the operation of the electric blower 110 (step S712). Step S713). In step S712, if the predetermined time has not elapsed (No in step S712), the control unit 118 repeats the operations from step S710.

After the electric blower 110 stops, the control unit 118 cancels the notification mode that notifies that the dust collection unit 112 is being cleaned (step S714). In the first embodiment, the display sections 1153a and 1153b installed on the operation switch section 115 of the vacuum cleaner 10 are turned off (see FIGS. 2A and 2B).

Note that in FIG. 5, the dust collection container 203 and the dust collection filter 204 are provided at the bottom of the first flow path 201, but the present invention is not limited to this configuration. Another example is shown in FIG. FIG. 8 is a partial cross-sectional view of a cleaning system according to a modification of the first embodiment of the present invention, taken along the vertical direction. In the modified example, the dust collection filter 204 is removed, and a ventilation member 203a with air permeability is arranged in a part (bottom) of the dust collection container 203. The air that has flowed into the dust collection container 203 passes through the ventilation portion of the dust collection container 203 and flows into the second flow path 202 . The ventilation member 203a has a function as a second dust collecting filter (dust collecting means) that collects dust.

As described above, according to the first embodiment, the dust collecting means (the second dust collecting means) having air permeability transfers dust from the dust collecting section 112 to the mounting table 20 side and filters the dust transferred to the mounting table 20 side. Since the dust collection filter (2) is provided on the mounting table 20 side, it is possible to suppress dust from rising from the mounting table 20, and it is possible to suppress malfunction of the switching valve 133 due to the lifted dust. As a result, the suction performance of the vacuum cleaner can be maintained.

Next, Example 2 will be described using FIG. 9. FIG. 9 is a partial cross-sectional view of the cleaning system according to the second embodiment of the present invention taken along the vertical direction. The same components as those in the first embodiment are denoted by the same reference numerals, and detailed explanations will be omitted.

The difference between the second embodiment and the first embodiment is the flow path configuration of the air flowing through the vacuum cleaner 10. In the first embodiment, when the vacuum cleaner 10 is placed on the mounting table 20, the air flowing through the main body passage 1101 flows into the dust storage space 1123 located downstream of the dust collection filter 1122 through the inlet 1121. However, in the second embodiment, the air flowing through the main body passage 1101 flows into the upstream space 1128 from the upstream opening 1127 located upstream of the dust collecting filter 1122.

When the vacuum cleaner 10 is used, air sucked in through the suction body 13, the extension pipe 12, and the main body passage 1101 flows into the dust collecting section 112 from the inlet 1121, as in the first embodiment.

The vacuum cleaner 10 is equipped with a dust collection channel switching mechanism (not shown), and in order to guide the air flowing through the main body passage 1101 to the upstream opening 1127, the dust collection channel switching mechanism is operated to switch the flow path. Switch.

The dust collection unit 112 is located directly above the first flow path 201 with the vacuum cleaner 10 placed on the mounting table 20. When the dust collection unit 112 and the mounting table 20 are connected, the dust collection lid 1125 is unlocked, and the dust collection lid 1125 opens toward the first flow path 201 using the hinge as a fulcrum. When the dust collection lid 1125 opens, the dust accumulated in the dust storage space 1123 of the dust collection section 112 falls toward the first flow path 201 due to gravity. Furthermore, after falling to the 201 side, the dust is compressed into the dust collection container 203 by the dust collection filter 204 . Here, the second embodiment is different from the first embodiment in that the first flow path and the second flow path are separated from each other. As a result, the upstream opening 1127 can be opened in the space direction, and outside air can be taken in.

In the flow path switching unit 130, when the vacuum cleaner 10 is placed on the mounting table 20, a part of the switching valve 133 contacts the mounting table 20, the switching valve 133 rotates, and the second flow path communication opening 132 is rotated. , and closes the dust collection section communication opening 1126.

When the vacuum cleaner 10 is placed on the mounting table 20 and the electric blower 110 is driven, the air flowing through the main body passage 1101 flows into the upstream space 1128 from the upstream opening 1127. The air that has flowed into the upstream space 1128 passes through the dust collection filter 1122, flows into the dust storage space 1123, and flows into the first flow path 201. At this time, the air passing through the dust filter 1122 removes dust attached to the dust filter 1122. That is, when the electric blower 110 is driven to automatically clean the dust collecting section 112, the direction of the air flowing through the dust collecting filter 1122 is reversed compared to when cleaning the floor surface. As a result, dust attached to the dust collection filter 1122 is removed. Since the subsequent air flow is the same as in Example 1, the explanation will be omitted.

According to the second embodiment, when automatically cleaning the dust collecting section 112, the direction of air flowing through the dust collecting filter 1122 is reversed compared to when cleaning the floor surface, so that the air that has adhered to the dust collecting filter 1122 is Dust can be removed and clogging of the dust filter 1122 can be suppressed.

In addition, in Example 2, as shown in FIG. 9, an example was shown in which the dust collection filter 204 was arranged between the first flow path 201 and the second flow path 202, but as shown in FIG. The filter 204 may be eliminated and a part of the dust collection container 203 may be provided with a ventilation member 203a having air permeability. In FIG. 8, since air flows through the air-permeable portion of the dust collection container 203, the dust contained in the dust collection container 203 is compressed by the air.

Next, Example 3 will be explained using FIG. 10. FIG. 10 is a partial cross-sectional view of the cleaning system according to the third embodiment of the present invention taken along the vertical direction. The same components as those in the first embodiment are denoted by the same reference numerals, and detailed explanations will be omitted.

The difference between the third embodiment and the first embodiment lies in the installation location of the dust collection container 203.

In the first embodiment, the dust collection container 203 was arranged at the bottom of the first flow path 201, but in the third embodiment, the dust collection container 203 was arranged between the first flow path 201 and the second flow path 202. ing. The dust collection container 203 is open toward the first flow path 201 side. Further, in the third embodiment, air is allowed to flow in from the upstream opening 1127, and the ventilation member 203a is arranged on the second flow path 202 side.

The dust collection lid 1125 is opened, and the dust that falls from the dust collection section 112 is deposited on the bottom of the first flow path 201. Air that flows into the first flow path 201 from the dust collecting section 112 by driving the electric blower 110 flows into the dust collecting container 203 and passes through the ventilation member 203a of the dust collecting container 203 having air permeability. At this time, the Terauchi 1124 deposited on the bottom of the first channel 201 is accommodated in the dust collecting container 203, and the accommodated dust 1124 is compressed with air.

According to the third embodiment, since the dust collection container 203 is arranged between the first flow path 201 and the second flow path 202, the volume that accommodates dust can be expanded.

Note that in the third embodiment, air is made to flow in from the upstream opening 1127, but it may be made to flow in from the inflow port 1121.

Next, Example 4 will be explained using FIG. 11. FIG. 11 is a partial cross-sectional view of the cleaning system according to the fourth embodiment of the present invention taken along the vertical direction. The same components as those in the first embodiment are denoted by the same reference numerals, and detailed explanations will be omitted.

The difference between the fourth embodiment and the first embodiment lies in the installation location of the dust collection container 203.

In the first embodiment, the dust collection container 203 is arranged at the bottom of the first flow path 201, but in the fourth embodiment, the dust collection container 203 is arranged at the second flow path 202. Furthermore, in the third embodiment, air is allowed to flow in from the upstream opening 1127.

The air that has flowed into the first flow path 201 from the dust collection section 112 flows into the second flow path 202 and further flows into the dust collection container 203. The air that has flowed into the dust collection container 203 passes through the air-permeable ventilation member 203a of the dust collection container 203. At this time, the dust contained in the dust collection container 203 is compressed with air.

According to the fourth embodiment, since the dust collection container 203 is disposed in the second flow path 202, the volume for accommodating dust can be expanded, and the flying up of dust can be further suppressed.

Note that in the fourth embodiment, air is made to flow in from the upstream opening 1127, but it may be made to flow in from the inflow port 1121.

The present invention is not limited to the embodiments described above, and includes various modifications. The embodiments described above are described in detail to explain the present invention in an easy-to-understand manner, and the present invention is not necessarily limited to those having all the configurations described.

Next, Example 5 will be described using FIGS. 12 and 13. FIG. 13 is a partial cross-sectional view of the cleaning system according to the embodiment of the present invention taken along the vertical direction. The same components as those in the first embodiment are denoted by the same reference numerals, and detailed explanations will be omitted. In Examples 2, 3, and 4, outside air flows in from the upstream opening 1127, and air also flows in from the main body passage 1101 as shown in FIG. In this case, since there are multiple inlets, dust attached to the dust collection filter 1122 cannot be efficiently removed. Therefore, in the fifth embodiment, it is desirable that a portion including the mouthpiece body 13 and the extension tube 12 be closed, so that air does not flow in from the main body passage 1101. For example, in FIG. 13, when the mouthpiece body 13 changes direction, it is closed by the closing portion 1301, and the extension pipe mouth side is closed. As a result, air does not flow in from the main body passage 1101, and the inflow port, which has been branched into two, is limited to one of the upstream openings 1127, and dust attached to the dust filter 1122 is efficiently removed.
