Embodiment 1.
1 and 2 are diagrams showing an example of the cleaning system 1 according to Embodiment 1. FIG. FIG. 3 is a diagram for explaining the functions of the cleaning system 1. As shown in FIG.

The cleaning system 1 comprises for example a vacuum cleaner 2 and a support device 3 . 1 and 2 show an example in which the cleaner 2 is a so-called stick-type cleaner. The vacuum cleaner 2 may not be a stick type. The support device 3 is placed, for example, in a living room. Vacuum cleaner 2 is supported by support device 3 .

The cleaner 2 is attachable to and detachable from the support device 3 . FIG. 1 shows a state in which the cleaner 2 is supported by the support device 3 . A user removes the cleaner 2 from the support device 3 when cleaning using the cleaner 2 . FIG. 2 shows the vacuum cleaner 2 removed from the support device 3 . The user attaches the vacuum cleaner 2 to the support device 3 after cleaning. The vacuum cleaner 2 is stored in a living room, for example, in the state shown in FIG.

The cleaner 2 comprises for example a head 4 , a suction tube 5 , a body 6 and a handle 7 . A suction port 4 a is formed in the head 4 . Head 4 may comprise a rotating brush. Head 4 is connected to one end of suction tube 5 . A suction pipe 5 is connected to the body 6 . The main body 6 includes a blower 8, a control device 9, a secondary battery 10, and a dust collection unit 11, for example.

A handle 7 is provided on the body 6 or the suction pipe 5 . In the example shown in this embodiment, the handle 7 is formed continuously with the suction pipe 5 in appearance. The handle 7 has an input device 12 . The input device 12 includes, for example, a power button and a button for switching operation modes. Information input from the input device 12 is input to the control device 9 .

The control device 9 controls the blower 8 based on information input from the input device 12 . Electric power is supplied from the secondary battery 10 to the blower 8 and the control device 9 . For example, when the user presses the power button of the input device 12, the blower 8 operates. As a result, an airflow is generated for sucking dust from the suction port 4a. Dust sucked from the suction port 4 a is sent to the main body 6 via the head 4 and the suction pipe 5 . The dust sent to the main body 6 is separated from the airflow and accumulated in the dust collection unit 11. - 特許庁Any method may be used for the dust collection unit 11 to separate the dust from the airflow. A user performs cleaning by holding the handle 7 and moving the head 4 back and forth.

The support device 3 comprises, for example, a main body 13 and a support base 14 . The main body 13 is arranged above the support base 14 . The support base 14 supports the main body 13 so that the main body 13 can be displaced around the shaft 15 . The shaft 15 is a vertically extending shaft. For example, the shaft 15 is centered vertically when the support device 3 is placed on a horizontal surface.

The main body 13 includes, for example, a main body case 20, a blower 21, a filter 22, a louver 23, a drive device 24, a drive device 25, a support 26, a sensor 27, an information acquisition device 28, an input device 29, a charging device 30, and a control device 31. Prepare.

The body case 20 is formed with an inlet 20a and an outlet 20b. At least the blower 21 and the filter 22 are arranged inside the body case 20 . In the example shown in FIGS. 1 and 2, the suction port 20a is formed on the front surface of the body case 20. As shown in FIG. The outlet 20b is formed on the upper surface of the body case 20. As shown in FIG. The formation position of the suction port 20a is not limited to the examples shown in FIGS. The formation position of the outlet 20b is not limited to the examples shown in FIGS. For example, the suction port 20 a may be formed on the side surface of the body case 20 .

The blower 21 draws in air through the inlet 20a and generates an airflow for blowing out the air through the outlet 20b. Air blower 21 is controlled by control device 31 .

The filter 22 is arranged inside the body case 20 . For example, the air sucked from the suction port 20a passes through the filter 22 immediately after passing through the suction port 20a. When the air sucked from the suction port 20a passes through the filter 22, the filter 22 captures dust contained in the air. The filter 22 is an example of a purifying device that purifies the air sucked from the suction port 20a. The main body 13 may further include a device other than the filter 22 as a cleaning device. The main body 13 may be provided with another device instead of the filter 22 as a cleaning device.

The louver 23 is plate-shaped, for example. The louver 23 is arranged at the outlet 20b. For example, the louver 23 is provided on the body case 20 via a shaft 23a. The louver 23 is displaceable around an axis 23a. The shaft 23a is a horizontal shaft extending left and right. For example, the shaft 23a is arranged horizontally with its center center when the support device 3 is placed on a horizontal surface. In this embodiment, an example in which a plurality of louvers 23 are arranged at the outlet 20b is shown.

The louver 23 is driven by a driving device 24. As shown in FIG. That is, when the driving device 24 operates, the louver 23 is displaced. The drive device 24 is controlled by a control device 31 .

The main body 13 includes a louver 23 and a driving device 24 as devices for setting the direction of the air blown from the outlet 20b. In the following description, this device will be referred to as a wind direction setting device. That is, by adjusting the inclination of the louver 23, the elevation/depression angle of the air blown out from the outlet 20b can be set.

In the example shown in this embodiment, the main body 13 further includes a driving device 25 as a wind direction setting device. The driving device 25 generates driving force for displacing the main body 13 with respect to the support base 14 . That is, when the driving device 25 operates, the main body 13 rotates around the shaft 15 . Drive device 25 is controlled by control device 31 . By adjusting the angle of the main body 13 with respect to the support base 14, the direction of the outlet 20b can be set in plan view. That is, it is possible to set the direction in which the air blows out from the blow-out port 20b. In addition, the driving device 25 may be provided on the support base 14 .

The support 26 is provided on the main body case 20 . The support 26 detachably supports the cleaner 2 . Any method may be used to support the cleaner 2 with the support 26 .

A sensor 27 detects that the cleaner 2 has come off the support 26 . Any method may be used for the sensor 27 to perform the above detection. For example, sensor 27 may be a proximity sensor. Sensor 27 may comprise a switch that is pressed when cleaner 2 is attached to support 26 . When the sensor 27 detects that the cleaner 2 has come off the support 26, it outputs a specific detection signal. A detection signal output from the sensor 27 is input to the control device 31 .

The information acquisition device 28 acquires specific information. The information acquisition device 28 outputs the acquired information to the control device 31 . 1 and 2 show an example in which the information acquisition device 28 is arranged in front of the main body case 20. FIG. The position of the information acquisition device 28 is not limited to the positions shown in FIGS. Specific functions of the information acquisition device 28 will be described later.

The input device 29 is a device operated by a user to input information. The input device 29 includes, for example, a power button and a button for switching operation modes. The input device 29 may be a touch panel. The input device 29 outputs a signal according to the user's operation. A signal output from the input device 29 is input to the control device 31 .

Charging device 30 is a device for charging secondary battery 10 provided in cleaner 2 . This embodiment shows an example in which the cleaner 2 is a cordless cleaner. That is, the main body 13 has a charging terminal 30a. The terminal 30 a is electrically connected to the secondary battery 10 of the cleaner 2 when the cleaner 2 is supported by the support 26 . The charging device 30 charges the secondary battery 10 via the terminal 30a. In this embodiment, an example in which the support device 3 functions as a charging stand for the cleaner 2 is shown. The support device 3 may not have the function of charging the cleaner 2 .

The control device 31 controls operation of the support device 3 . FIG. 4 is a diagram for explaining the functions of the control device 31. As shown in FIG. The control device 31 includes a storage unit 40, a determination unit 41, an identification unit 42, a detection unit 43, and an operation control unit 44, for example.

Information necessary for controlling the operation of the support device 3 is stored in the storage unit 40 . The determination unit 41 determines whether the cleaner 2 is attached or detached. The identification unit 42 identifies the person using the cleaner 2 . The detection unit 43 detects the direction of the person using the cleaner 2 . That is, the detection unit 43 detects in which direction the person using the cleaner 2 is when viewed from the support device 3 . The operation control unit 44 controls operation of the support device 3 in a plurality of operation modes. The operation of the support device 3 will be described below with reference to FIGS. 5 to 7 as well.

FIG. 5 is a flow chart showing an operation example of the support device 3 . Specifically, FIG. 5 shows the processing flow of the control device 31 . The determination unit 41 determines whether or not the cleaner 2 has been removed from the support 26 (S101). As described above, when the sensor 27 detects that the cleaner 2 has come off the support 26 , the sensor 27 outputs a detection signal to the control device 31 . If the detection signal from the sensor 27 is not input to the control device 31, the determination unit 41 determines No in S101.

When determined as No in S101, the operation control unit 44 controls the blower 21 and the wind direction setting device in the normal operation mode (S102). In the normal operation mode, the operation control unit 44 controls the blower 21 and the wind direction setting device based on information input from the input device 29, for example. The operation control unit 44 may control the blower 21 and the wind direction setting device based on the degree of pollution of the air. The operation control unit 44 may stop the blower 21 in S102.

As described above, the user removes the cleaner 2 from the support device 3 when using the cleaner 2 . When the user removes the cleaner 2 from the support device 3 , the sensor 27 detects that the cleaner 2 is removed from the support 26 . When the detection signal from the sensor 27 is input to the control device 31, the determination unit 41 determines Yes in S101. When determined as Yes in S101, the operation control unit 44 controls the blower 21 and the wind direction setting device in the first operation mode (S103).

In the first operation mode, for example, a first airflow is formed for sucking dust that is blown up by the vacuum cleaner 2 through the suction port 20a. 6 and 7 are diagrams for explaining the function of the cleaning system 1. FIG. 6 and 7 show an example in which the support device 3 is placed in a room 50. FIG. FIG. 6 is a side view of the room 50. FIG. FIG. 7 is a diagram of the room 50 viewed from above.

As shown in FIG. 6, the air blown obliquely upward from the outlet 20b of the support device 3 moves along the ceiling 51, the walls 52, and the floor 53 of the room 50 as indicated by the arrow A, and reaches the inlet. It is sucked into the support device 3 from 20a. In this embodiment, such an air flow is called a first air flow.

In order to form the first airflow, the angle of the louver 23 must be set according to the shape of the room 50 and the direction in which the outlet 20b faces. Data indicating the shape of the room 50 is stored in the storage unit 40 . For example, data indicating the distance from the support device 3 to the wall 52 and data indicating the height of the ceiling 51 are stored in the storage unit 40 . The data indicating the shape of the room 50 may be manually input by the user. The main body 13 may further include a device for automatically measuring data indicating the shape of the room 50 .

In the first operation mode, the identifying unit 42 identifies the person using the cleaner 2 (S104). For example, the identification unit 42 identifies a person who is in a specific detection range when the sensor 27 detects that the cleaner 2 has come off from the support 26 as the person using the cleaner 2 .

For example, information acquisition device 28 is a camera. Information about the image captured by the information acquisition device 28 is input to the control device 31 . The identification unit 42 identifies a person within the detection range by performing specific processing on the image captured by the information acquisition device 28 . The detection range is set in advance based on, for example, the position where the person who is trying to remove the cleaner 2 from the support 26 stands.

The detection unit 43 detects the direction of the person identified by the identification unit 42 based on the information obtained by the information obtaining device 28 (S105). In order to realize the above function of the detection unit 43 , the information acquisition device 28 acquires information necessary for tracking the person identified by the identification unit 42 . The information acquisition device 28 may be any device as long as it can acquire the above information. For example, the information acquisition device 28 may be a thermography. The information acquisition device 28 may be a distance sensor. The information acquisition device 28 may be a motion sensor. The information acquisition device 28 may be composed of a plurality of devices.

In the example shown in this embodiment, the detection unit 43 does not need to detect the position of the person identified by the identification unit 42 . The detection unit 43 only needs to be able to detect in which direction the person identified by the identification unit 42 is in at least a plan view. Note that the detection unit 43 may detect the position of the person identified by the identification unit 42 .

As shown in FIG. 7, the operation control unit 44 causes the airflow corresponding to the direction detected by the detection unit 43 to be generated from the outlet 20b (S106). For example, the operation control unit 44 generates an obliquely upward airflow as shown in FIG. As a result, the first airflow as shown in FIG. 6 is generated in the room 50 where the person using the cleaner 2 is present. FIG. 7 shows an example in which the user indicated by symbol B is specified by the specifying unit 42 in S104.

As shown in FIGS. 6 and 7, the operation control unit 44 generates the first airflow that passes over the user B in S106. That is, the air blown out from the blowout port 20b passes over the user B, and then forms a downdraft on the wall 52 on the opposite side. Air descending along the wall 52 moves along the floor 53 towards the supporting device 3 . Therefore, the dust C blown up by the user B using the vacuum cleaner 2 is moved so as to approach the support device 3 by the first air current. In FIGS. 6 and 7, the dust moved by the first airflow is indicated by symbol C'. Dust C approaching the support device 3 is sucked into the main body 13 through the suction port 20a.

When the first operation mode is started in S103, the determination unit 41 determines whether or not the cleaner 2 is attached to the support device 3 (S107). For example, the determination unit 41 makes the determination of S107 based on the signal from the sensor 27 . If it is determined No in S107, the processes shown in S105 and S106 are continuously performed. If determined as Yes in S107, the operation control unit 44 terminates the first operation mode. When determined as Yes in S107, the operation control unit 44 controls the blower 21 and the wind direction setting device in the normal operation mode (S102).

In the example shown in Embodiment 1, when the sensor 27 detects that the vacuum cleaner 2 is removed from the support 26, the support device 3 starts the first operation mode. In the first operation mode, the support device 3 causes the airflow corresponding to the direction detected by the detector 43 to be generated from the outlet 20b. Therefore, with the cleaning system 1, indoor air can be efficiently cleaned when the cleaner 2 cleans.

Other functions that can be employed by the cleaning system 1 are described below.

In the present embodiment, an example of forming the first airflow in the first operation mode has been described. As another example, the second airflow may be formed in the first operating mode. The second air current is an air current for suppressing dust from being blown up by the vacuum cleaner 2 .

FIG. 8 is a diagram for explaining other functions of the cleaning system 1. As shown in FIG. FIG. 8 shows an example in which the support device 3 is placed in a room 50, similar to FIG. FIG. 8 is a side view of the room 50. FIG.

As shown in FIG. 8, the air blown sideways from the blowout port 20b of the support device 3 travels in a straight line in the room 50 as indicated by the arrow D and reaches the wall 52. As shown in FIG. As a result, an air curtain is formed at the height of the outlet 20b for suppressing dust from being blown up. In this embodiment, such an air flow is called a second air flow.

In S106, the operation control unit 44 causes the airflow corresponding to the direction detected by the detection unit 43 to be generated from the outlet 20b, as shown in FIG. For example, the operation control unit 44 generates a lateral airflow from the outlet 20b in the direction detected by the detection unit 43, as shown in FIG. As a result, a second airflow as shown in FIG. 8 is generated in the room 50 where the person using the cleaner 2 is present. In the example shown in FIGS. 8 and 7, it is possible to prevent the dust C from being stirred up when the user B uses the vacuum cleaner 2 . Therefore, indoor air can be efficiently cleaned when cleaning is performed by the cleaner 2 .

As another example, both the first airflow and the second airflow may be formed in the first operating mode. FIG. 9 is a diagram for explaining other functions of the cleaning system 1. As shown in FIG. FIG. 9 shows an example in which the support device 3 is placed in a room 50, similar to FIG. FIG. 9 is a side view of the room 50. FIG.

As shown in FIG. 9, the air blown obliquely upward from the outlet 20b of the support device 3 moves along the ceiling 51, the walls 52, and the floor 53 of the room 50 as indicated by the arrow A, and moves toward the inlet. It is sucked into the support device 3 from 20a. Also, the air blown sideways from the blowout port 20b of the support device 3 advances in a straight line in the room 50 as indicated by the arrow D. As shown in FIG.

In S106, the operation control unit 44 causes the airflow corresponding to the direction detected by the detection unit 43 to be generated from the outlet 20b, as shown in FIG. For example, the operation control unit 44 simultaneously generates an obliquely upward airflow and a sideways airflow as shown in FIG. In the example shown in FIGS. 9 and 7, the dust C generated by the user B using the vacuum cleaner 2 can be efficiently sucked through the suction port 20a. Furthermore, it is possible to prevent the dust C from being stirred up when the user B uses the vacuum cleaner 2 .

In the present embodiment, an example in which both the suction port 20a and the discharge port 20b are formed in the body case 20 rotatable with respect to the support base 14 has been described. This is an example. FIG. 10 is a diagram showing another example of the cleaning system 1. As shown in FIG.

In the example shown in FIG. 10, the support device 3 comprises a main body 13 and a movable body 16, for example. The movable body 16 is arranged above the main body 13 . The main body 13 supports the movable body 16 so that the movable body 16 can be displaced around the shaft 17 . The shaft 17 is a vertically extending shaft. For example, the shaft 17 is centered vertically when the support device 3 is placed on a horizontal surface.

In the example shown in FIG. 10, the body case 20 is formed with a suction port 20a. The outlet 20 b is formed in the movable body 16 . For example, the outlet 20b is formed on the upper surface of the movable body 16. As shown in FIG. The louver 23 is arranged at the outlet 20b. For example, the louver 23 is provided on the movable body 16 via a lateral shaft 23a. The driving device 24 may be provided on the body case 20 or may be provided on the movable body 16 .

In the example shown in FIG. 10 , the driving device 25 generates driving force for displacing the movable body 16 with respect to the main body 13 . That is, when the driving device 25 operates, the movable body 16 rotates around the shaft 17 . By adjusting the angle of the movable body 16 with respect to the main body 13, the direction of the outlet 20b can be set in plan view. That is, it is possible to set the direction in which the air blows out from the blow-out port 20b.

FIG. 11 is a flow chart showing another operation example of the support device 3 . The process flow shown in FIG. 11 is obtained by adding a series of processes shown from S108 to S110 to the process flow shown in FIG. FIG. 11 shows an example in which the operation control section 44 controls the blower 21 and the wind direction setting device in the second operation mode when a specific condition is established.

In the second operation mode, a third air current is formed to discharge dust that has been lifted up by the vacuum cleaner 2 to the outside of the room. 12 and 13 are diagrams for explaining other functions of the cleaning system 1. FIG. 12 and 13 show an example in which the support device 3 is placed in a room 50. FIG. 12 is a side view of the room 50. FIG. FIG. 13 is a diagram of the room 50 viewed from above. In the example shown in FIGS. 12 and 13 , a window 54 is provided in the wall 52 of the room 50 . Moreover, in the examples shown in FIGS. 12 and 13 , the control device 31 further includes a determination section 45 . The determination unit 45 makes a determination regarding the second operation mode.

As shown in FIG. 12, the air laterally blown out from the blowout port 20b of the support device 3 travels in a straight line in the room 50 as indicated by the arrow E, and is discharged out of the room 50 through the window 54. . In this embodiment, such an air flow is called a third air flow.

As described above, when the first operation mode is started in S103, the determination unit 41 determines whether or not the cleaner 2 is attached to the support device 3 (S107). If determined as No in S107, the determination unit 45 determines whether or not the second operation mode is valid (S108). For example, the input device 29 is provided with a button for enabling the second operating mode. If this button is not pressed by the user, the determination unit 45 does not determine that the second operation mode is valid (No in S108). If determined as No in S108, the first operation mode is continued. If the button is pressed by the user, the determination unit 45 determines that the second operation mode is valid (Yes in S108).

If the second operation mode is set to be valid, the determination unit 45 determines whether or not the direction detected by the detection unit 43 is within a specific setting range (S109). For example, the setting range is set in advance according to the direction in which the window 54 exists. FIG. 13 shows an example in which a determination of Yes is made in S109 when the direction detected by the detection unit 43 is within the set range α in plan view. In addition, if it determines with No by S109, a 1st driving mode will be continued.

When determined as Yes in S109, the operation control unit 44 controls the blower 21 and the wind direction setting device in the second operation mode (S110). As described above, in the second operation mode, the third air current is formed for discharging the dust that has been stirred up by the vacuum cleaner 2 to the outside of the room. In the second operation mode, the operation control unit 44 generates a downward airflow from the outlet 20b at a higher speed than the airflow generated from the outlet 20b in the first operation mode. After that, when the direction detected by the detection unit 43 deviates from the set range α, the operation control unit 44 terminates the second operation mode. The operation control unit 44 restarts the first operation mode.

In the example shown in FIG. 11, the process of S108 may not be performed. In such a case, if the determination in S107 is No, the determination in S109 is performed.

Embodiment 2.
Embodiment 1 describes an example in which the detection unit 43 of the control device 31 detects the direction of the person using the cleaner 2 . In this embodiment, an example in which detection unit 43 detects the direction in which cleaner 2 is present will be described.

FIG. 14 is a diagram for explaining functions of the cleaning system 1 according to the second embodiment. In the example shown in FIG. 14 , cleaner 2 further includes transmitter 18 . The transmitter 18 emits radio waves, for example, at regular intervals. Transmitter 18 may emit radio waves only when vacuum cleaner 2 is removed from support 26 . The body 13 of the support device 3 further comprises a receiver 32 . The receiver 32 receives radio waves emitted by the transmitter 18 . In the example shown in FIG. 14, the main body 13 may not have the information acquisition device 28 .

FIG. 15 is a flow chart showing an operation example of the support device 3 . The processing from S201 to S203 in FIG. 15 is the same as the processing from S101 to S103 in FIG. When it is determined as Yes in S201, the operation control unit 44 controls the blower 21 and the wind direction setting device in the first operation mode (S203).

In the first operation mode, the direction in which cleaner 2 is present is detected by detector 43 (S204). As described above, receiver 32 receives radio waves emitted by transmitter 18 . Based on the radio waves received by the receiver 32, the detection unit 43 detects the direction in which the cleaner 2 is present in S204. In the example shown in the present embodiment as well, detection unit 43 does not need to detect the position of cleaner 2 . The detection unit 43 only needs to be able to detect in which direction the cleaner 2 is present at least in plan view. Note that the detection unit 43 may detect the position of the cleaner 2 .

The processes shown in S205 and S206 in FIG. 15 are the same as the processes shown in S106 and S107 in FIG. That is, as shown in FIG. 7, the operation control unit 44 causes the airflow corresponding to the direction detected by the detection unit 43 to be generated from the outlet 20b (S205). For example, the operation control unit 44 generates an obliquely upward airflow as shown in FIG. As a result, a first airflow as shown in FIG. 6 is generated in the room 50 where the cleaner 2 is used.

When the first operation mode is started in S203, the determination unit 41 determines whether or not the cleaner 2 is attached to the support device 3 (S206). When it is determined as Yes in S206, the operation control unit 44 controls the blower 21 and the wind direction setting device in the normal operation mode (S202).

In the example shown in the second embodiment, when the sensor 27 detects that the cleaner 2 is removed from the support 26, the support device 3 starts the first operation mode. In the first operation mode, the support device 3 causes the airflow corresponding to the direction detected by the detector 43 to be generated from the outlet 20b. Therefore, with the cleaning system 1, indoor air can be efficiently cleaned when the cleaner 2 cleans.

As for the functions of the cleaning system 1 that are not described in this embodiment, any of the functions described in the first embodiment may be employed. For example, the support device 3 may comprise a main body 13 and a movable body 16, as in the example shown in FIG. If the control device 31 determines No in S206, the control device 31 may perform the same processing as the processing shown in S108 to S110 of FIG.

In Embodiments 1 and 2, when the sensor 27 detects that the vacuum cleaner 2 is removed from the support 26, the operation control unit 44 controls the blower 21 and the wind direction setting device in the first operation mode. explained. This is an example.

For example, the body 13 of the support device 3 may further include a sensor for detecting that the cleaner 2 has started operating. For example, the vacuum cleaner 2 wirelessly transmits a specific signal when the power button of the input device 12 is pressed to operate the fan 8 . When the sensor provided on the body 13 of the support device 3 receives this signal wirelessly transmitted from the cleaner 2, it detects that the cleaner 2 has started operating.

In such a case, another determination function of the control device 31 determines in S101 of FIG. 5 whether or not the operation of the cleaner 2 has been started. When the sensor detects that the operation of the cleaner 2 has started (Yes in S101), the operation control unit 44 controls the blower 21 and the wind direction setting device in the first operation mode (S102).

When the user uses the cleaner 2 , it is expected that the user will detach the cleaner 2 from the support device 3 and then press the power button of the input device 12 . Therefore, in parallel with the determination process of S101, the determination process of whether or not the cleaner 2 has come off the support 26 may be performed. Then, when the sensor 27 detects that the vacuum cleaner 2 is removed from the support 26, the processing shown in S105 and S106 is performed. In the first operation mode, the operation control unit 44 causes the airflow corresponding to the direction detected by the detection unit 43 to be generated from the outlet 20b (S106).

In the example shown in FIG. 15, another determination function of the control device 31 determines in S201 whether or not the operation of the cleaner 2 has been started. When the sensor detects that the operation of the cleaner 2 has started (Yes in S201), the operation control unit 44 controls the blower 21 and the wind direction setting device in the first operation mode (S203). The process shown in S204 of FIG. 15 may be started when the sensor detects that the operation of the cleaner 2 has started, or when the sensor detects that the cleaner 2 is removed from the support 26. 27 may be initiated.
