Description

Cleaning system

The present invention relates to a cleaning system equipped with an electric cleaning machine.

As a previous electric cleaning device, there is a technology described in Patent Document 1. The electric cleaning device of Patent Document 1 comprises: an electric cleaning machine, which houses a first dust collecting part, an electric blower, and a secondary battery for feeding power to the electric blower in a cleaning machine body; and a device body, which detachably carries the cleaning machine body of the electric cleaning machine.

The device body includes: a second dust collecting part, which is connected to the first dust collecting part of the electric cleaner when the cleaner body is installed on the device body; and a charging power supply mechanism, which feeds electricity to the secondary battery of the electric cleaner to charge the secondary battery.

An upper opening communicating with the outside is formed at the upper part of the first dust collecting part of the electric cleaner, and a first valve body for opening and closing the upper opening is provided at the upper opening.

In addition, a waste opening is formed at the bottom of the first dust collecting part of the electric cleaner, and a dust collecting part lower cover for opening and closing the waste opening is provided at the waste opening. When the cleaner body is mounted on the device body, the waste opening connects the first dust collecting part with the second dust collecting part.

Furthermore, a lower opening is formed at the lower part of the electric blower chamber that accommodates the electric blower of the electric cleaner, so that the outside of the cleaner body and the electric blower chamber are connected, and a second valve body for opening and closing the lower opening is arranged at the lower opening. In addition, an auxiliary filter is arranged at the lower opening.

Furthermore, in Patent Document 1, after cleaning is completed, the cleaning machine body is mounted on the device body, the secondary battery is charged, and the first valve body, the second valve body, and the lower cover of the dust collecting section are opened. When the lower cover of the dust collecting section is opened, most of the dust collected in the first dust collecting section falls to the second dust collecting section by its own gravity and is collected by the dust collecting housing provided in the second dust collecting section.

Furthermore, in Patent Document 1, the electric blower is driven to generate negative pressure, and the external air is captured from the upper opening to the first dust collecting section. The external air captured to the first dust collecting section passes through the dust collecting housing of the second dust collecting section, is sucked into the electric blower through the lower opening and the auxiliary filter, and is discharged to the outside of the cleaner body from the exhaust hole provided in the cleaner body.

The negative pressure generated by the electric blower causes the dust remaining in the first dust collecting section and the dust attached to the main filter to fall into the dust collecting casing and be captured in the dust collecting casing.

[Prior technical literature] [Patent literature] [Patent literature 1] Japanese Patent Publication No. 2008-79922

[Problems to be solved by the invention] In the technology described in Patent Document 1, when the electric blower is driven to remove dust remaining in the first dust collecting section and dust attached to the main filter, dust flying from the dust collecting housing provided in the second dust collecting section is captured by the auxiliary filter arranged at the lower opening of the electric cleaner. Therefore, when a large amount of dust is attached to the auxiliary filter, the second valve body does not completely close the lower opening, and when the electric cleaner is used for cleaning, dust flows into the outside air from the lower opening, which may reduce the suction performance of the electric cleaner.

Furthermore, in Patent Document 1, when the cleaner body is removed from the device body, dust collected by the sub-filter may fall through the lower opening and the dust may fly.

The object of the present invention is to provide a cleaning system which can suppress the decline of suction performance and the flying of dust.

[Technical means to solve the problem] In order to achieve the above-mentioned purpose, the cleaning system of the present invention is characterized in that it includes: an electric cleaner, which includes: an electric blower; a dust collecting part, which has a first dust collecting filter inside and collects dust by the suction force of the electric blower; and a main body passage, which is connected to the dust collecting part; and a mounting table, which carries the electric cleaner and recovers the dust collected in the dust collecting part; and the mounting table includes: a first flow path, which is located below the dust collecting part when the electric cleaner is carried; a second flow path, which is adjacent to the first flow path and one end is connected to the first flow path; and a second dust collecting filter, which is arranged in the flow path formed by the first flow path and the second flow path, and has ventilation.

[Effect of the invention] According to the present invention, the following cleaning system can be provided: since the dust discharged from the dust collecting part to the side of the placing table is captured by the second dust collecting filter arranged on the side of the placing table, the decrease in the suction performance of the electric cleaner side due to dust adhesion is suppressed, and the flying of dust from the placing table is suppressed.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. The same components are denoted by the same symbols, and the same description will not be repeated.

The various components of the present invention do not necessarily have to exist independently. It is allowed that one component includes multiple components, multiple components are composed of one component, a certain component is a part of other components, a part of a certain component overlaps with a part of other components, etc.

[Example 1] Figure 1 is a perspective view of an electric cleaning machine mounted on a mounting table in Example 1 of the present invention. Figure 2A is a diagram showing an example of a switch button of an operating switch unit. Figure 2B is a diagram showing another example of a switch button of an operating switch unit. In Example 1, front and back, left and right, and up and down are defined based on the user's viewpoint when cleaning.

In FIG1 , the cleaning system 1 includes: an electric cleaning machine 10; and a mounting table 20 that supports the electric cleaning machine 10. The mounting table 20 also serves as a charging table for the electric cleaning machine 10. When the electric cleaning machine 10 is not in use, it is placed on the mounting table 20 for charging.

The electric cleaner 10 includes: a cleaner body 11; an extension tube 12, one end of which is connected to the cleaner body 11; and a suction port 13, which is connected to the extension tube at the other end.

The grip part 113 is provided with an operation switch part 115.

As shown in FIG. 2A , the operation switch unit 115 is provided with: an operation control button 1151a for selecting the operation of the electric blower 110; an automatic cleaning control button 1151b (manual start button) for executing automatic cleaning of the dust collecting unit 112; an off button 1152 for stopping the operation of the electric blower 110; and a display unit 1153a for displaying the remaining amount of the battery 114, the maintenance of the filter, and the automatic cleaning status of the dust collecting unit 112. In Embodiment 1, the operation control button 1151a has two modes, namely, "strong" and "standard". In addition, the operation control button 1151a also serves as the automatic cleaning control button 1151b (manual start button). By pressing the "standard" button for 3 seconds, the automatic cleaning described below is executed. Furthermore, the automatic cleaning control button 1151b may be omitted, and the dust in the dust collecting part may be cleaned simultaneously with the electric cleaner placed on the mounting table 20.

In FIG. 2A, the operation control button 1151a and the automatic cleaning control button 1151b are configured to be both, but the operation control button 1151a and the automatic cleaning control button 1151b may be configured separately, for example, as shown in FIG. 2B. In FIG. 2B, the automatic cleaning control button 1151b is configured independently of the operation control button 1151a. Furthermore, in FIG. 2B, a display unit 1153b is provided around the automatic cleaning control button 1151b.

FIG3 is a control block diagram of the cleaning system of Embodiment 1 of the present invention. An AC adapter 21 is connected to the mounting table 20 to convert alternating current into direct current. A female connector 23 is electrically connected to the AC adapter 21 via a power cord 22. The electric cleaning machine 10 includes: a male connector 116, which is connected to the female connector 23 of the mounting table 20 when mounted on the mounting table 20; and a control unit 118, which is connected to the male connector 116 via a power cord 117. The control unit 118 includes: a memory unit, which stores control programs required for the operation and charging of the electric cleaning machine 10; and a central processing unit, which executes the control program. Furthermore, the battery 114 and the electric blower 110 are connected to the control unit 118 and controlled by the control unit 118. The battery 114 is electrically connected to the male connector 116 via the control unit 118.

Fig. 4 is a cross-sectional view of the electric cleaner 10 of the embodiment 1 of the present invention cut along the up-down direction. Fig. 4 shows the flow of air when the electric cleaner 10 is in use. In Fig. 4, the extension tube 12 and the suction port 13 connected to the electric cleaner 10 are omitted.

The dust collecting part 112 is detachably mounted on the cleaning machine body 11. A body passage 1101 communicating with the dust collecting part 112 is formed in the cleaning machine body 11 connected to the extension tube 12. The outlet of the body passage 1101 is connected to the inlet 1121 of the dust collecting part 112.

The dust collecting section 112 is provided with a dust collecting filter 1122 (first dust collecting filter) for filtering 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. A dust collecting cover 1125 for discarding the dust 1124 collected in the dust storage space 1123 is openably provided below the dust collecting section 112 (on the opposite side of the electric blower).

Furthermore, a flow path switching portion 130 is provided above the dust collecting portion (on the electric blower side or downstream side). The flow path switching portion 130 is located between the dust collecting portion 112 and the electric blower 110. A dust collecting portion connecting opening 1126 is formed between the dust collecting portion 112 and the flow path switching portion 130 to connect the dust collecting portion 112 and the flow path switching portion 130.

The electric blower side opening 131 communicating with the inlet of the electric blower 110 is formed on the electric blower side (downstream side) of the flow path switching portion 130. Also, the flow path switching portion 130 has a second flow path communicating opening 132 communicating with the second flow path of the mounting table 20 described later.

Furthermore, a switching valve 133 is provided in the flow path switching portion 130 to open and close the dust collecting portion connecting opening 1126 and the second flow path connecting opening 132. The switching valve 133 operates in such a manner that when either the dust collecting portion connecting opening 1126 or the second flow path connecting opening 132 is closed, the other is opened. Furthermore, in this embodiment, the switching valve 133 is not limited to a valve body, and may be any switching mechanism as long as it can switch the flow path.

When cleaning the floor, the electric cleaner 10 is removed from the mounting platform 20. At this time, the switching valve 133 operates in a manner of opening the dust collecting portion communication opening 1126 and closing 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 to operate and generates suction. The suction port 13 contacts the ground, and the dust on the ground is sucked together with the air. The air and dust sucked from the suction port 13 flow into the dust collecting section 112 through the extension tube 12 and the inlet 1121. The air and dust 1124 flowing into the dust collecting section 112 are filtered by the dust collecting filter 1122. The air passes through the dust collecting filter 1122, and the dust 1124 is captured in the dust receiving space 1123. The air passing through the dust filter 1122 passes through the flow path switching portion 130, is sucked by the electric blower 110 from the side opening 131 of the electric blower, and is discharged outside the cleaning machine body.

Furthermore, a male connector 116 connected to the female connector 23 of the mounting table 20 is provided on the cleaning machine body 11.

Next, the action after the cleaning is completed is described. FIG. 5 is a partial cross-sectional view of the main part of the cleaning system of Embodiment 1 of the present invention cut along the up and down direction. After the cleaning is completed, the electric cleaner 10 is placed on the mounting table 20 as shown in FIG. 5, and charging is started. In Embodiment 1, the feature is that the dust collected in the dust collecting part 112 of the electric cleaner 10 is transferred to the dust collecting container 203 of the mounting table 20. That is, the mounting table 20 has the function of recovering the dust collected in the dust collecting part 112. The following is a description of this structure.

The mounting table 20 includes: a first flow path 201, which is located below the dust collecting part 112 when the electric cleaner 10 is mounted on the mounting table 20 and extends downward; and a second flow path 202, which is adjacent to the first flow path 201 and extends upward. The first flow path 201 is arranged at a position extending from the bottom of the dust collecting part 112, and the second flow path 202 is arranged at a position offset from the bottom of the dust collecting part 112. A dust collecting container 203 is provided at the bottom of the first flow path 201 to receive dust falling from the dust collecting part 112. The upper opening of the dust collecting container 203 is detachably provided from the mounting table 20.

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

The dust collecting container 203 can be constructed to have ventilation, and a paper bag filter having the same effect can be used. The paper bag filter can be detached from the mounting table 20. When the dust collected in the paper bag filter is full, the dust collecting performance can be restored by replacing it with a new paper bag filter.

One end of the first flow path 201 is connected to the dust collecting portion 112 , and the other end is connected to one end of the second flow path 202 via the dust collecting filter 204 .

One end of the second flow path 202 is connected to the other end of the first flow path 201 , and the other end is connected to the flow path switching unit 130 via the second flow path connecting opening 132 .

When the electric cleaner 10 is placed on the mounting table 20, the dust collecting part 112 is located directly above the first flow path 201. When the dust collecting part 112 is connected to the mounting table 20, the lock of the dust collecting cover 1125 is released, and the dust collecting cover 1125 is opened toward the first flow path 201 with the hinge as a fulcrum. When the dust collecting cover 1125 is opened, the dust accumulated in the dust containing space 1123 of the dust collecting part 112 falls toward the first flow path 201 side by gravity.

In the flow path switching portion 130 , a portion of the flow path switching portion 130 abuts against the mounting table 20 , and the switching valve 133 rotates to open the second flow path communication opening 132 and close the dust collecting portion communication opening 1126 .

When the dust collecting cover 1125 is opened, the dust accumulated in the dust containing space 1123 of the dust collecting section 112 falls toward the first flow path 201 by gravity, and a portion of the dust may sometimes adhere to the dust collecting filter 1122 or the wall of the dust collecting section 112.

In the first embodiment, the electric blower 110 is driven to discharge the dust remaining in the dust collecting part 112. Next, the action of discharging the dust remaining in the dust collecting part 112 to the side of the loading table is described using FIG. 5 and FIG. 6. FIG. 6 is an action flow chart of the automatic cleaning mode of the dust collecting part 112 under the automatic operation of the first embodiment of the present invention. In the first embodiment, the so-called automatic cleaning means driving the electric blower 110 when the electric cleaner 10 is placed on the loading table.

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

Next, the control unit 118 performs detection control of charging the battery 114 (step S602) and detects whether the battery 114 is charged (step S603). When the control unit 118 determines that the battery 114 is charged (step S603 is yes), the battery 114 is continuously charged (step S604). When the control unit 118 determines that the battery 114 is not charged (step S603 is no), the operation from step S602 is repeated. The control unit 118 determines whether the electric cleaner 10 is placed on the mounting table 20 based on whether the battery 114 is charged in step S603. That is, if at least the battery 114 is charged, it is determined that the electric cleaner 10 is placed on the placement table 20.

Whether the electric sweeper 10 is placed on the mounting table 20 can be determined by combining the charging status of the aforementioned storage battery 114 with a mechanical grounding sensor (not shown) provided on the suction port body 13. The grounding sensor is a detection mechanism that prevents the rotating brush (not shown) provided on the suction port body 13 from being driven when it is off the ground. As shown in FIG1 , since the suction port body 13 is grounded when the electric sweeper 10 is placed on the mounting table 20, the grounding can be detected by the grounding sensor of the suction port body 13. In other words, when the storage battery 114 is being charged and it can be determined by the grounding sensor that the suction port body 13 is grounded, it can be determined that the electric sweeper 10 is placed on the mounting table 20. Thereby, even if the power cord 22 and the female connector 23 can be removed from the mounting table 20 , it can be reliably determined that the electric cleaner 10 is mounted on the mounting table 20 .

The control unit 118 detects the remaining amount of the battery 114 and determines whether the remaining amount of the battery 114 is greater than a specific amount (step S605). When the remaining amount of the battery 114 is greater than the specific amount (step S605: yes), the control unit 118 determines whether a specific time has passed since the electric cleaner 10 was placed on the mounting table 20 (since the dust collector 112 was shifted to the automatic cleaning mode) (step S606). The specific time is the time set based on the time from when the electric cleaner 10 is intended to be placed on the mounting table 20, the time from when the dust cover 1125 is opened and the dust 1124 falls into the dust container 203, the time from when the electric cleaner 10 is placed on the mounting table 20 to when the user leaves the mounting table 20, etc.

When the remaining amount of the battery 114 is not greater than the specified amount (No in step S605) and the specified time has not passed since the electric cleaner 10 was placed on the mounting table 20 (No in step S606), the operation from step S604 is repeated.

In step S606, when a specific time has passed after the electric cleaner 10 is placed on the mounting table 20 (Yes in step S606), the control unit 118 executes a notification mode for notifying the dust collecting unit 112 that the dust collecting unit 112 is in automatic cleaning (step S607). In the notification mode of embodiment 1, the display units 1153a and 1153b of the operating switch unit 115 provided on the electric cleaner 10 are lit (refer to FIG. 2A and FIG. 2B).

After executing the notification mode, the control unit 118 drives the electric blower 110 (step S608) to perform automatic cleaning of the dust collecting unit 112.

Here, return to FIG. 5 to explain the automatic cleaning operation of the dust collecting section 112. During the automatic cleaning of the dust collecting section 112, air flows as indicated by the arrows. When the electric blower 110 is driven, air is sucked in through the suction port 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 , so that the dust 1124 attached to the dust collecting filter 1122 and the inner surface of the dust collecting section 112 is peeled off and flows into the first flow path 201 together with the dust 1124 .

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

The air flowing into the second flow path 202 rises in the second flow path 202 and flows into the flow path switching unit 130 from the second flow path connecting opening 132. The air flowing into the flow path switching unit 130 is sucked by the electric blower 110 from the electric blower side opening 131 and discharged to the outside of the cleaning machine body. In this way, the automatic cleaning of the dust collecting unit 112 is performed.

Returning to FIG. 6 , the control unit 118 determines whether a specific time has passed after the electric blower 110 is driven (step S609). If the specific time has passed (step S609: Yes), the operation of the electric blower 110 is stopped (step S610). In step S609, if the specific time has not passed (step S609: No), the control unit 118 repeats the action from step S607.

After the electric blower 110 stops, the control unit 118 cancels the notification mode of the automatic cleaning (step S611). In the first embodiment, the display units 1153a and 1153b of the operation switch unit 115 provided in the electric cleaner 10 are turned off (refer to FIG. 2A and FIG. 2B).

Through the above steps, the automatic cleaning of the dust collecting section 112 is completed. In the above-mentioned embodiment, it is assumed that when the electric cleaner 10 is placed on the mounting table 20, the dust collecting section 112 is automatically cleaned, but it can also be manually cleaned according to the user's intention. The manual mode is explained using Figure 7. Figure 7 is an action flow chart of the automatic cleaning mode of the dust collecting section 112 under manual operation of Embodiment 1 of the present invention. In Figure 7, even if it is a manual operation, the action of cleaning the dust collecting section 112 is called the automatic cleaning mode. Manual operation is to drive the electric blower 110 according to the user's intention.

When cleaning is completed and the electric 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 performs detection control of charging the battery 114 (step S702). The control unit 118 determines whether the manual start button (automatic cleaning control button 1151b: refer to Figure 2B) of the dust collection unit 112 is pressed (step S703). In embodiment 1, manual cleaning is started by pressing the "standard" of the operation control button 1151 of the operation switch unit 115 for 3 seconds.

When the manual cleaning start button (automatic cleaning control button 1151b) is pressed (Yes in step S703), the control unit 118 detects whether to charge the battery 114 (step S704).

When the manual start button (auto-cleaning control button 1151b) is not pressed (No in step S703), the action from step S702 is repeated.

When the control unit 118 determines that the battery 114 is to be charged (Yes in step S704), the battery 114 is continuously charged (step S705). When the control unit 118 determines that the battery 114 is not to be charged (No in step S704), it notifies that charging cannot be started (step S706), and repeats the operation from step S702. The method of notifying that charging cannot be started is, for example, to make the charging symbol (battery symbol) in FIG. 2 flash.

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

The control unit 118 detects the remaining amount of the battery 114 and determines whether the remaining amount of the battery 114 is greater than a specific amount (step S707). When the remaining amount of the battery 114 is greater than the specific amount (yes in step S707), the control unit 118 determines whether a specific time has passed since the electric cleaner 10 was placed on the mounting table 20 (since the mode of manual cleaning of the dust collecting unit 112 was shifted to start) (step S708). The specific time is the time set based on the intention to place the electric cleaner 10 on the mounting table 20, the time from when the dust collecting cover 1125 is opened and the dust falls into the dust collecting container 203, the time from when the electric cleaner 10 is placed on the mounting table 20 to when the user leaves the mounting table 20, etc.

When the remaining amount of the battery 114 is not more than a certain amount (No in step S707) and the electric cleaner 10 has not been placed on the mounting table 20 for a certain period of time (No in step S708), a preparation mode is notified (step S709), and the operation from step S705 is repeated. The preparation mode, for example, causes the display units 1153a and 1153b to flash (see FIG. 2A and FIG. 2B).

In step S708, when a specific time has passed after the electric cleaner 10 is placed on the mounting table 20 (Yes in step S708), the control unit 118 executes a notification mode for notifying that the dust collecting unit 112 is cleaning (step S710). In the notification mode of embodiment 1, the display units 1153a and 1153b of the operating switch unit 115 provided on the electric cleaner 10 are lit (refer to FIG. 2A and FIG. 2B).

After executing the notification mode, the control unit 118 drives the electric blower 110 (step S711) to clean the dust collecting unit 112.

The cleaning operation of the dust collecting section 112 is the same as the automatic cleaning described with reference to FIG. 5 , so the description thereof will be omitted.

The control unit 118 determines whether a specific time has passed after the electric blower 110 is driven (step S712). If the specific time has passed (step S712: yes), the electric blower 110 is stopped (step S713). In step S712, if the specific time has not passed (step S712: no), the control unit 118 repeats the action from step S710.

After the electric blower 110 stops, the control unit 118 cancels the notification mode for notifying that the dust collecting unit 112 is cleaning (step S714). In the first embodiment, the display units 1153a and 1153b of the operating switch unit 115 provided on the electric cleaner 10 are turned off (refer to FIG. 2A and FIG. 2B).

Furthermore, in FIG. 5 , a dust collecting container 203 and a dust collecting filter 204 are provided at the bottom of the first flow path 201, but the present invention is not limited to this configuration. FIG. 8 shows another example. FIG. 8 is a partial cross-sectional view of a cleaning system of a variation of the embodiment 1 of the present invention cut along the up and down directions. In the variation, the dust collecting filter 204 is removed, and a ventilation component 203a with air permeability is arranged at a part (bottom) of the dust collecting container 203. The air flowing into the dust collecting container 203 passes through the ventilation part of the dust collecting container 203 and flows into the second flow path 202. The ventilation component 203a has the function of serving as a second dust collecting filter (dust collecting mechanism) for capturing dust.

As described above, according to Embodiment 1, since dust is transferred from the dust collecting section 112 to the side of the mounting table 20, a dust collecting mechanism (second dust collecting filter) having ventilation properties for filtering the dust transferred to the side of the mounting table 20 is provided on the side of the mounting table 20, so that the flying of dust from the mounting table 20 can be suppressed, and the malfunction of the switching valve 133 due to the flying dust can be suppressed. As a result, the suction performance of the electric cleaner can be maintained.

[Example 2] Next, Example 2 is described using FIG. 9 . FIG. 9 is a partial cross-sectional view of the cleaning system of Example 2 of the present invention cut along the up and down direction. The same symbols are attached to the same components as Example 1, and detailed descriptions are omitted.

In the second embodiment, the difference from the first embodiment is the flow path structure of the air flowing through the electric cleaner 10. In the first embodiment, when the electric cleaner 10 is placed on the mounting table 20, the air flowing through the main body passage 1101 flows into the dust receiving space 1123 located on the downstream side of the dust filter 1122 through the inlet 1121, but 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 on the upstream side of the dust filter 1122.

The use of the electric cleaner 10 is the same as that of the embodiment 1. The air sucked in through the suction mouth 13, the extension tube 12, and the main body passage 1101 flows into the dust collecting part 112 from the inlet 1121.

The electric cleaner 10 is provided with a dust collecting flow path switching mechanism (not shown). When the air flowing through the main body passage 1101 is guided toward the upstream opening 1127, the dust collecting flow path switching mechanism is activated to switch the flow path.

The dust collecting part 112 is located directly above the first flow path 201 when the electric cleaner 10 is placed on the mounting table 20. When the dust collecting part 112 is connected to the mounting table 20, the lock of the dust collecting cover 1125 is released, and the dust collecting cover 1125 is opened toward the first flow path 201 with the hinge as a fulcrum. When the dust collecting cover 1125 is opened, the dust accumulated in the dust storage space 1123 of the dust collecting part 112 falls toward the first flow path 201 side by gravity. Further, after falling toward the 201 side, the dust is compressed into the dust collecting container 203 by the dust collecting filter 204. Here, Embodiment 2 is different from Embodiment 1 in that the first flow path is separated from the second flow path. Thus, the upstream opening 1127 can be opened toward the separated space and can capture the external atmosphere.

In the flow path switching portion 130 , when the electric cleaner 10 is placed on the mounting table 20 , a portion of the switching valve 133 abuts against the mounting table 20 , and the switching valve 133 rotates to open the second flow path communication opening 132 and close the dust collecting portion communication opening 1126 .

When the electric 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 flowing into the upstream space 1128 passes through the dust filter 1122, flows into the dust storage space 1123, and flows toward the first flow path 201. At this time, the air passing through the dust filter 1122 removes the dust attached to the dust filter 1122. That is, in the automatic cleaning of the dust collecting part 112 of the electric blower 110, the direction of the air flowing through the dust filter 1122 becomes reversed relative to the floor cleaning. In this way, dust adhering to the dust collecting filter 1122 is removed. Since the following air flow is the same as that in Embodiment 1, the description thereof is omitted.

According to Embodiment 2, when the dust collecting part 112 is automatically cleaned, the direction of air flowing through the dust filter 1122 becomes reversed compared to when the floor is cleaned, so the dust attached to the dust filter 1122 can be removed and the clogging of the dust filter 1122 can be suppressed.

Furthermore, in the second embodiment, as shown in Fig. 9, the dust filter 204 is arranged between the first flow path 201 and the second flow path 202. However, as shown in Fig. 8, the dust filter 204 may be eliminated and a ventilation member 203a having ventilation properties may be provided in a part of the dust container 203. In Fig. 8, since air flows through the ventilation portion of the dust container 203, the dust contained in the dust container 203 is compressed by the air.

[Example 3] Next, Example 3 is described using FIG. 10 . FIG. 10 is a partial cross-sectional view of the cleaning system of Example 3 of the present invention cut along the up and down direction. The same symbols are attached to the same components as Example 1, and detailed descriptions are omitted.

In embodiment 3, the difference from embodiment 1 lies in the location of the dust collecting container 203.

In the first embodiment, the dust collecting container 203 is arranged at the bottom of the first flow path 201, but in the third embodiment, the dust collecting container 203 is arranged between the first flow path 201 and the second flow path 202. The dust collecting container 203 opens toward the side of the first flow path 201. In the third embodiment, air flows in from the upstream opening 1127, and the ventilation member 203a is arranged on the side of the second flow path 202.

The dust collecting cover 1125 is opened, and the dust falling from the dust collecting part 112 is accumulated at the bottom of the first flow path 201. The electric blower 110 is driven, and the air flowing from the dust collecting part 112 into the first flow path 201 flows into the dust collecting container 203, and passes through the ventilation member 203a with air permeability of the dust collecting container 203. At this time, the dust 1124 accumulated at the bottom of the first flow path 201 is contained in the dust collecting container 203, and the contained dust 1124 is compressed by the air.

According to the third embodiment, since the dust collecting container 203 is disposed between the first flow path 201 and the second flow path 202, the dust collecting capacity can be enlarged.

Furthermore, in Embodiment 3, air is assumed to flow in from the upstream opening 1127 , but air may also flow in from the inlet 1121 .

[Example 4] Next, Example 4 is described using FIG. 11. FIG. 11 is a partial cross-sectional view of the cleaning system of Example 4 of the present invention cut along the up and down direction. The same symbols are attached to the same components as Example 1, and detailed descriptions are omitted.

In embodiment 4, the difference from embodiment 1 lies in the location of the dust collecting container 203.

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

The air flowing into the first flow path 201 from the dust collecting section 112 flows into the second flow path 202 and then flows into the dust collecting container 203. The air flowing into the dust collecting container 203 passes through the ventilation member 203a having air permeability of the dust collecting container 203. At this time, the dust contained in the dust collecting container 203 is compressed by the air.

According to the fourth embodiment, since the dust collecting container 203 is arranged in the second flow path 202, the dust collecting capacity can be expanded and the flying of dust can be further suppressed.

Furthermore, in Embodiment 4, air is assumed to flow in from the upstream opening 1127 , but air may also flow in from the inlet 1121 .

The present invention is not limited to the above-mentioned embodiments, but includes various variations. The above-mentioned embodiments are described in detail to explain the present invention in an easy-to-understand manner, and are not limited to having all the described structures.

[Example 5] Next, Example 5 is described using Figures 12 and 13. Figure 13 is a partial cross-sectional view of the cleaning system of the embodiment of the present invention cut along the up and down direction. The same symbols are attached to the same components as Example 1, and detailed descriptions are omitted. Regarding Examples 2, 3, and 4, the outside air flows in from the upstream opening 1127, and as shown in Figure 12, air also flows in from the main body passage 1101. In this case, since there are multiple inlets, dust attached to the dust filter 1122 cannot be removed efficiently. Therefore, in Example 5, it is ideal that a portion including the suction port body 13 or the extension tube 12 is locked, and air does not flow in from the main body passage 1101. For example, in FIG. 13 , if the suction port body 13 changes direction, the locking portion 1301 is locked, and the suction port side of the extension tube is locked. As a result, air does not flow into the main body passage 1101, and the two branched inlets are limited to one of the upstream openings 1127, thereby efficiently removing dust attached to the dust filter 1122.
