Description

Cleaning system and control method of cleaning system

[0001] The present disclosure relates to a cleaning system including a cleaner and a station and a method for controlling the cleaning system.

[0002] The vacuum cleaner may include a manual vacuum cleaner that moves around a cleaning space while being operated directly by the user and cleans up dirt such as dust accumulated on the floor, and a robot vacuum cleaner that automatically cleans a cleaning space by moving around a cleaning space without being operated by the user and sucking up dirt such as dust accumulated on the floor.

[0003] Recently, vacuum cleaners have emerged that not only suck up dust and other foreign substances from the floor, but also wipe them away. Vacuum cleaners can also perform wet cleaning using a mop.

[0004] Among robot vacuum cleaners and manual vacuum cleaners, cordless vacuum cleaners are equipped with batteries, allowing them to freely clean the cleaning space without connecting a power cord.

[0005] Cordless vacuum cleaners and robot vacuum cleaners can be arranged to be placed on a station for charging the batteries.

[0006] Recently, stations have been developed that not only charge the vacuum cleaner's battery while the vacuum cleaner is stationed, but also suck up dust from the vacuum cleaner's dust bin and store it in the station's dust bin, or wash and / or dry the vacuum cleaner's mop.

[0007] The present disclosure provides a cleaning system capable of preventing water splashing during a washing cycle and a method for controlling the cleaning system.

[0008] The present disclosure provides a cleaning system and a control method of the cleaning system that prevent electrical hazards that may occur due to steam during a washing cycle.

[0081] The vacuum cleaner (10) may include a lifting drive unit (162, see FIG. 14) that moves the mop (160) up and down. While the vacuum cleaner (10) is cleaning, the lifting drive unit (162) may move the mop (160) downward. This allows the mop (160) to come into contact with the surface to be cleaned. While the vacuum cleaner (10) completes cleaning and returns to the station (20), the lifting drive unit (162) may move the mop (160) upward. This allows the mop (160) to be separated from the surface to be cleaned. This prevents the mop (160) from colliding with an obstacle on the surface to be cleaned or from leaving unnecessary moisture on the surface to be cleaned while the vacuum cleaner (10) is moving to the station (20). As will be described later, the control unit (190, see FIG. 14) of the vacuum cleaner (10) can control the lifting drive unit (162) to move the mop (160) up and down.

[0175] For convenience of explanation, the control unit (190) of the vacuum cleaner (10) is referred to as the first control unit (190) below.

[0176] The docking sensor (150s) can communicate with the docking sensor (250s) of the station (20) in a non-contact manner using electromagnetic waves such as infrared rays, visible light, or ultrasonic waves. The docking sensor (150s) is provided at the rear of the main body (110), and when the cleaner (10) docks to the station (20), it can exchange electromagnetic waves (e.g., infrared rays) with the docking sensor (250s) of the station (20).

[0177] The docking sensor (150s) can detect infrared rays reflected from the docking sensor (250s) after irradiating infrared rays, and output the intensity of the detected infrared rays, or the time interval (Time Of Flight: TOF) from the irradiation of infrared rays to the detection of the reflected infrared rays, to the first control unit (190).

[0178] The docking sensor (150s) can detect infrared rays irradiated from the docking sensor (250s) of the station (20) and output the intensity of the detected infrared rays, or the time interval (Time Of Flight: TOF) from the irradiation of the infrared rays until the reflected infrared rays are detected, to the first control unit (190).

[0179] The first control unit (190) can control the driving unit (120) based on data collected from the docking sensor (150s) when the cleaner (10) must be docked to the station (20).

[0180] The obstacle detection sensor (170) detects obstacles that impede the movement of the vacuum cleaner (10). An obstacle may refer to any object protruding from the floor of the cleaning area and impeding the movement of the vacuum cleaner (10). For example, not only tables, sofas, etc. located in the cleaning area, but also walls dividing the space may be considered obstacles, and objects that the vacuum cleaner (10) can climb up and down, such as thresholds or round bars, may also be considered obstacles.

[0181] Specifically, the obstacle detection sensor (170) can detect obstacles in a non-contact manner using electromagnetic waves such as infrared rays, visible light, or ultrasonic waves. For example, the obstacle detection sensor (170) can detect infrared rays reflected from an obstacle after irradiating infrared rays, and output the intensity of the detected infrared rays, or the time interval (Time Of Flight: TOF) between irradiating infrared rays and detecting the reflected infrared rays, to the first control unit (190).

[0182] The first control unit (190) can calculate the presence or absence of an obstacle or the distance between the obstacle and the vacuum cleaner (10) based on the output value of the obstacle detection sensor (170).

[0186] The first control unit (190) can calculate the presence or absence of an obstacle or the distance between the obstacle and the vacuum cleaner (10) based on the image acquired by the obstacle detection sensor (170).

[0187] The humidity sensor (171) may include at least one sensor for measuring the humidity (or moisture content) of the mop (160).

[0188] In one embodiment, the humidity sensor (171) can measure changes in moisture in the air. The humidity sensor (171) is provided around the mop (160) to measure the humidity (or moisture content) of the mop (160). In this case, the output humidity of the humidity sensor (171) can be proportional to the moisture content of the mop (160).

[0189] The first control unit (190) can determine the humidity (or moisture content) of the mop (160) based on the humidity measured from the humidity sensor (171).

[0190] In one embodiment, the humidity sensor (171) can irradiate the mop (160) with light such as infrared or visible light or electromagnetic waves such as ultrasonic waves and then measure the intensity of the electromagnetic waves reflected from the mop (160) and / or the time interval from the irradiation of the electromagnetic waves until the reflected electromagnetic waves are detected.

[0191] For example, the humidity sensor (171) may include a light emitting portion that irradiates light to the mop (160) and a light receiving portion that receives light reflected from the mop (160).

[0192] The first control unit (190) can determine the humidity (or moisture content) of the mop (160) based on the output value of the humidity sensor (171).

[0193] The first control unit (190) can perform various operations depending on the humidity (or moisture content) of the mop (160). For example, the first control unit (190) can control the driving unit (120) to return the cleaner (10) to the station (20) based on the humidity of the mop (160) being measured to be higher than a predetermined maximum humidity. As another example, the first control unit (190) can control the driving unit (120) to return the cleaner (10) to the station (20) based on the humidity of the mop (160) being measured to be lower than a predetermined minimum humidity.

[0194] The battery (150) can supply power to various electrical components of the vacuum cleaner (10). The battery (150) can be charged while the vacuum cleaner (10) is placed on the station (20).

[0208] In one embodiment, the user interface (181) may include an input interface for receiving a mop wash command and / or a mop steam command.

[0209] If the user determines that washing or sterilizing the mop (160) of the vacuum cleaner (10) is necessary, the user can input a mop washing command and / or a mop steam command through the input interface.

[0210] The vacuum cleaner (10) can return to the station (20) when a mop cleaning command and / or a mop steam command is input through the input interface.

[0211] When a mop cleaning command and / or a mop steam command is input through the input interface, the cleaner (10) can transmit a mop cleaning request signal and / or a mop steam request signal to the station (20).

[0212] Accordingly, when the cleaner (10) returns to the station (20) and is docked at the station (20), the station (20) can perform a washing cycle (e.g., a washing cycle and / or a steam cycle).

[0333] Fig. 16 is a flowchart showing an example of a control method of a cleaning system according to one embodiment.

[0334] For convenience of explanation, it is assumed below that the control unit (190, 290) of the cleaning system (1) includes a first control unit (190) and a second control unit (290).

[0335] The first control unit (190) and the second control unit (290) can transmit and receive various types of information through the communication units (182, 282). The first control unit (190) can control the operation of the vacuum cleaner (10). The second control unit (290) can control the operation of the station (20).

[0336] Referring to FIG. 16, the control unit (190, 290) can determine whether a cleaner (10) is installed at the station (20) (1010).

[0337] In one embodiment, the control unit (190) can determine whether the cleaner (10) is docked on the station (20) based on processing data collected by the docking sensor (150s). The control unit (190) can determine that the cleaner (10) is docked on the station (20) based on the start of charging of the cleaner (10).

[0338] In one embodiment, the control unit (290) can determine whether the cleaner (10) is docked on the station (20) based on processing data collected by the docking sensor (250s). The control unit (290) can determine that the cleaner (10) is docked on the station (20) based on the start of charging of the cleaner (10).

[0339] The control unit (190, 290) can determine whether the start condition of the washing cycle is satisfied (1020).

[0340] In one embodiment, the control unit (190) may determine that the start condition of the washing cycle is satisfied based on receiving a washing command through the user interface (181) or receiving a washing command from an external device through the communication unit (182).

[0341] In one embodiment, the control unit (190) may complete cleaning according to a preset cleaning schedule or determine that the start condition of the washing cycle is satisfied based on the humidity value measured from the humidity sensor (171) falling within a preset range.

[0342] When the control unit (190) determines that the start condition of the washing cycle is satisfied, the control unit (190) can control the communication unit (182) to transmit a signal requesting the washing cycle to the station (20).

[0343] In one embodiment, the control unit (290) may determine that the start condition of the washing cycle is satisfied based on receiving a washing command through the user interface (281) or receiving a washing command from an external device through the communication unit (282).

[0344] When the control unit (290) determines that the start condition of the washing cycle is satisfied, the control unit (290) can control the communication unit (282) to transmit a signal requesting the cleaner (10) to return to the station (20).

[0345] In one embodiment, the control unit (290) may determine that the start condition of the washing cycle is satisfied based on the fact that the cleaner (10) has been re-mounted after being detached from the station (20).

[0346] Depending on various embodiments, the order of operations 1010 and 1020 may be changed.

[0347] The control unit (190, 290) can start the washing cycle based on the satisfaction of the start condition of the washing cycle.

[0348] In the present disclosure, the washing cycle may include a steam cycle and / or a washing cycle.

[0349] The steam cycle and / or the washing cycle may include operating a heating device (250) to provide heated water (steam) to a mop (160) accommodated in a washing chamber (230).

[0350] The control unit (190, 290) can lower the mop (160) to a first position based on the start of the washing cycle (1030). Here, the first position may correspond to a position where the mop (160) is seated on the washing frame (240). That is, when the mop (160) is positioned at the first position, the mop (160) can come into contact with the washing frame (240).

[0351] The control unit (190, 290) can drive the heating device (250) based on the start of the washing cycle (1040). For example, the control unit (190, 290) can drive the heating device (250) after lowering the mop (160) to the first position.

[0352] Here, driving the heating device (250) includes supplying heated water and / or steam (hereinafter collectively referred to as “steam”) to the washing chamber (230).

[0353] The control unit (190) can transmit a descent completion signal to the control unit (290) in response to the completion of the descent of the mop (160) to the first position, and the control unit (290) can drive the heating device (250) in response to receiving the descent completion signal from the control unit (190).

[0354] That is, the control unit (190, 290) can drive the heating device (250) in response to the completion of the lowering of the mop (160) to the first position.

[0355] The control unit (190, 290) can rotate the mop (160) during the washing cycle. As the mop (160) rotates, the washing and / or sterilization of the mop (160) can be performed more smoothly.

[0356] Meanwhile, when the heating device (250) is operated, steam is discharged to the outside of the cleaning chamber (230), which may cause water to form around the main body (110) of the cleaner (10) and / or the station (20).

[0357] A sensor window corresponding to a docking sensor (150s) may be provided around the main body (110) of the vacuum cleaner (10). A sensor window corresponding to a docking sensor (250s) may be provided at the station (20).

[0358] If steam is discharged outside the cleaning chamber (230) and water forms around the main body (110) of the cleaner (10) and / or the station (20), water may form on the sensor window, causing a docking detection error.

[0359] Additionally, if steam is discharged outside the cleaning chamber (230) and water forms around the main body (110) of the cleaner (10) and / or the station (20), the area around the main body (110) of the cleaner (10) and / or the station (20) may become contaminated.

[0360] In addition, if steam is discharged outside the cleaning chamber (230) and water forms around the main body (110) of the cleaner (10) and / or the station (20), water may also form on the charging terminal (151, 218), which may cause an electrical hazard when charging the battery (150) of the cleaner (10).

[0361] Accordingly, there is a need to prevent water from forming around the main body (110) of the cleaner (10) and / or the station (20) by discharging steam to the outside of the washing chamber (230) during the washing cycle.

[0362] The control unit (190, 290) can drive at least one of the drying unit (260) of the station (20) or the suction motor (142) of the cleaner (10) while the heating unit (250) is being driven (1050).

[0363] The station (20) can operate the drying device (260) while steam is supplied to the washing chamber (230) by operating the heating device (250).

[0364] By operating the drying device (260) while steam is supplied to the cleaning chamber (230), air can flow to the main body (110) of the cleaner (10).

[0365] The vacuum cleaner (10) can drive the suction motor (142) while steam is supplied to the cleaning chamber (230) by driving the heating device (250).

[0366] By driving the suction motor (142) while steam is supplied to the cleaning chamber (230), air drawn into the interior of the main body (110) of the cleaner (10) can flow to the exterior of the main body (110) of the cleaner (10).

[0367] That is, the control unit (190, 290) can drive the drying device (260) and / or the suction motor (142) while the mop (160) is positioned at the first position.

[0368] Driving the drying device (260) and / or the suction motor (142) while the heating device (250) is being driven may include not only turning on the drying device (260) and / or the suction motor (142) while the heating device (250) is being driven, but also turning on the drying device (260) and / or the suction motor (142) before or after the heating device (250) is being driven. Furthermore, the control unit (190, 290) may turn on the drying device (260) and / or the suction motor (142) after the heating device (250) is stopped after being driven.

[0369] Driving at least one of the drying device (260) or the suction motor (142) may include driving only the drying device (260), driving only the suction motor (142), or driving both the drying device (260) and the suction motor (142).

[0370] Driving the drying device (260) may include rotating a fan (262).

[0371] Driving the suction motor (142) may include rotating a suction fan.

[0372] According to the present disclosure, by driving at least one of the drying device (260) of the station (20) or the suction motor (142) of the cleaner (10) while the heating device (250) is being driven, water can be prevented from forming around the main body (110) of the cleaner (10) and / or the station (20).

[0373] FIG. 17 schematically illustrates the flow of air supplied by the drying device of the station while the mop of the vacuum cleaner is positioned in the first position according to one embodiment.

[0374] Referring to FIG. 17, the mop (160) can come into contact with the washing frame (240) while positioned in the first position.

[0375] For example, the mop (160) may come into contact with the guide member (240g) (or frame body (240a)).

[0376] In the present disclosure, the washing chamber (230) is a space defined by a chamber floor (230a) and a chamber side wall (230b) extending upward from the chamber floor (230a), a portion of which (cl) may be open. Accordingly, the washing chamber (230) may be referred to as an open chamber, an open room, a niche, or a wall.

[0377] The open part (cl) can correspond to the frame opening (240c) described above.

[0378] In the present disclosure, when an open part (cl) is closed by a mop (160), the washing chamber (230) may be a space defined by a chamber bottom (230a), a chamber side wall (230b), and a frame body (240a).

[0379] A mop (160) can be accommodated in the washing chamber (230) through the open portion (cl) of the washing chamber (230).

[0380] The fact that the mop (160) is accommodated in the washing chamber (230) may mean that the mop (160) is included within a space defined by the chamber floor (230a) and the chamber side wall (230b) extending upward from the chamber floor (230a).

[0381] The mop (160) can close an open portion (cl) of the washing chamber (230) while positioned at the first position. Accordingly, the washing chamber (230) can be defined by the mop (160), the chamber side wall (230b), and the guide member (240g).

[0382] That is, the washing chamber (230) can be closed while the mop (160) is positioned at the first position. In the present disclosure, closing the washing chamber (230) may include closing an open portion (cl) of the washing chamber (230).

[0383] When the open part (cl) of the washing chamber (230) is closed and the washing chamber (230) is defined by the mop (160), the chamber side wall (230b), and the guide member (240g), the inside of the washing chamber (230) may mean the inside of the space defined by the mop (160), the chamber side wall (230b), and the guide member (240g), and the outside of the washing chamber (230) may mean the outside of the space defined by the mop (160), the chamber side wall (230b), and the guide member (240g).

[0384] Meanwhile, as described above, the open part (cl) of the washing chamber (230) is closed by a mop (160) through which fluid is easily permeable, so that steam provided into the interior of the washing chamber (230) can leak out of the washing chamber (230).

[0385] The dry air supply unit (232) can be divided into a first flow path (242a) and a second flow path (242b) by a guide member (240g). The first flow path (242a) can be a flow path provided on the upper side of the guide member (240g), and the second flow path (242b) can be a flow path provided on the lower side of the guide member (240g).

[0386] The steam nozzle (243) illustrated in Fig. 12 may be provided on the lower side of the guide member (240g) to supply steam into the interior of the washing chamber (230).

[0387] When the mop (160) is positioned at the first position, the second flow path (242b) faces the inside of the washing chamber (230) defined by the mop (160), the chamber floor (230a), the chamber side wall (230b), and the guide member (240g), and the first flow path (242a) faces the outside of the washing chamber (230) defined by the mop (160), the chamber floor (230a), the chamber side wall (230b), and the guide member (240g).

[0388] In one embodiment, when the mop (160) is positioned at the first position and the guide member (240g) and the mop (160) come into contact, the air flowing into the first flow path (242a) may be directed toward the outside of the washing chamber (230), and the air flowing into the second flow path (242b) may be directed toward the inside of the washing chamber (230).

[0389] Since the washing chamber (230) is a closed space, when air is supplied to the drying air supply unit (232), the pressure inside the washing chamber (230) may become higher than the pressure outside the washing chamber (230). Accordingly, while the mop (160) is positioned at the first position, the air supplied to the washing chamber (230) by the operation of the drying device (260) may flow relatively more to the outside of the washing chamber (230) than to the inside of the washing chamber (230).

[0390] Here, the interior of the washing chamber (230) may be the washing chamber (230) itself, and the exterior of the washing chamber (230) may mean a space outside the washing chamber (230).

[0391] While the mop (160) is positioned at the first position, the air flowing out of the washing chamber (230) through the first flow path (242a) by the operation of the drying device (260) can flow into the space between the docking sensor (150s) of the cleaner (10) and the docking sensor (250s) of the station (20).

[0392] While the mop (160) is positioned at the first position, the air flowing out of the washing chamber (230) through the first flow path (242a) by the operation of the drying device (260) can dry the water formed around the main body (110) of the cleaner (10) and / or the station (20).

[0393] According to the present disclosure, by operating the drying device (260) during the washing cycle, water formed around the main body (110) of the cleaner (10) and / or the station (20) can be immediately removed.

[0394] According to the present disclosure, by operating the drying device (260) during the washing cycle, water formed on the docking sensor (150s) of the cleaner (10) and / or the docking sensor (250s) of the station (20) can be immediately removed.

[0395] According to the present disclosure, since the steam nozzle (243) is provided on the lower side of the guide member (240g) and the steam is supplied into the interior of the cleaning chamber (230) defined by the mop (160), the chamber side wall (230b), and the guide member (240g) while the mop (160) is positioned at the first position, an excessive amount of steam can be prevented from being transmitted to the periphery of the main body (110) of the cleaner (10) and / or the station (20).

[0396] According to the present disclosure, since the heating device (250) is driven in response to the completion of the lowering of the mop (160) to the first position, an excessive amount of steam can be prevented from being transferred to the surroundings of the main body (110) of the cleaner (10) and / or the station (20).

[0397] Figure 18 schematically illustrates the flow of air according to the operation of the suction motor of a vacuum cleaner according to one embodiment.

[0398] Referring to Fig. 18, when the suction motor (142) is driven, air sucked into the suction port (111) can pass through the dust collector (142) and be discharged to the discharge port (112).

[0399] In one embodiment, the outlet (112) may be provided on the lower side of the docking sensor (150s) (see FIG. 5).

[0400] When the suction motor (142) is driven, the air discharged through the exhaust port (112) can flow into the space between the cleaner (10) and the station (20).

[0401] For example, when the suction motor (142) is driven, the air discharged through the exhaust port (112) can flow into the space between the docking sensor (150s) of the cleaner (10) and the docking sensor (250s) of the station (20).

[0402] For this purpose, the discharge port (112) may be provided at a position facing the docking sensor (250s) of the station (20) while the cleaner (10) is mounted on the station (20).

[0403] While the cleaner (10) is placed on the station (20), the docking sensor (250s) of the station (20) and the docking sensor (150s) of the cleaner (10) can face each other.

[0404] When the suction motor (142) is driven, the air discharged through the discharge port (112) is blown toward the station (20), and the air reflected from the station (20) flows toward the cleaner (10), thereby removing water formed on the station (20) and the main body of the cleaner (10).

[0405] For example, when the suction motor (142) is driven, the air discharged through the outlet (112) is blown toward the docking sensor (250s) of the station (20), and the air reflected from the docking sensor (250s) of the station (20) flows toward the docking sensor (150s) of the cleaner (10), thereby removing water formed on the docking sensor (250s) of the station (20) and the docking sensor (150s) of the cleaner (10).

[0406] According to the present disclosure, by driving the suction motor (142) during the washing cycle, water formed around the main body (110) of the cleaner (10) and / or the station (20) can be immediately removed.

[0407] According to the present disclosure, by driving the suction motor (142) of the cleaner (10) during the washing cycle, water formed on the docking sensor (150s) of the cleaner (10) and / or the docking sensor (250s) of the station (20) can be immediately removed.

[0408] Meanwhile, when the suction motor (142) of the vacuum cleaner (10) is operated during the washing cycle, noise may be generated, which may cause discomfort to the user.

[0409] In one embodiment, the control unit (190, 290) can control the driving strength of the suction motor (142) during the washing cycle to be weaker than the driving strength of the suction motor (142) during the cleaning cycle of the cleaner (10).

[0410] For example, the control unit (190, 290) can drive the suction motor (142) at a first intensity while the cleaner (10) is performing cleaning, and drive the suction motor (142) at a second intensity that is weaker than the first intensity while the heating device (250) is being driven.

[0411] Driving the suction motor (142) at the first speed may include rotating the suction motor (142) at the first rotational speed. Driving the suction motor (142) at the second speed, which is weaker than the first speed, may include rotating the suction motor (142) at the second rotational speed, which is slower than the first rotational speed.

[0412] Driving the suction motor (142) at the first intensity may include driving the suction motor (142) at the first duty ratio. Driving the suction motor (142) at the second intensity, which is weaker than the first intensity, may include driving the suction motor (142) at the second duty ratio, which is smaller than the first duty ratio.

[0413] According to the present disclosure, noise generated by the operation of the suction motor (142) during the washing cycle can be minimized.

[0414] According to various embodiments, the control unit (190, 290) can receive information about the presence of a person in the home from an external device through the communication unit (182, 282).

[0415] Here, ‘inside the house’ may mean an indoor space where the station (20) is installed.

[0416] The control unit (190, 290) may increase the intensity of the suction motor (142) based on the absence of people in the house during the washing cycle. Here, increasing the intensity of the suction motor (142) may mean driving the suction motor (142) at an intensity greater than the second intensity.

[0417] According to the present disclosure, when there is no person in the house, the strength of the suction motor (142) can be increased to more efficiently remove water formed around the main body (110) of the cleaner (10) and / or the station (20).

[0418] Referring again to FIG. 16, the control unit (190, 290) can determine whether the end condition of the washing cycle is satisfied (1060).

[0419] The end condition of the washing cycle may include various conditions, such as the washing cycle execution time having elapsed for a preset period of time, or a command to start the drying cycle having been received.

[0420] The control unit (190, 290) may stop the heating device (250) (1070) based on the satisfaction of the end condition of the washing cycle (example of 1060). In various embodiments, the heating device (250) may be intermittently stopped even during the washing cycle, and the washing cycle may be ended with the heating device (250) stopped before the end of the washing cycle.

[0421] The control unit (190, 290) can stop the drying unit (260) and / or the suction motor (142) based on the stopping of the heating unit (250) (1080).

[0422] According to various embodiments, the control unit (190, 290) may not stop the operation of the drying unit (260) and / or the suction motor (142) for a predetermined period of time even if the heating unit (250) is stopped.

[0423] That is, the control unit (190, 290) can maintain the operation of the drying device (260) and / or the suction motor (142) for a predetermined period of time after the heating device (250) is stopped.

[0424] According to the present disclosure, water formed around the main body (110) of the cleaner (10) and / or at the station (20) can be efficiently removed.

[0425] According to various embodiments, the control unit (190, 290) may not stop the operation of the drying device (260) and / or the suction motor (142) if the drying cycle is to be performed after the end of the washing cycle. That is, operation 1080 may be omitted.

[0426] In one embodiment, the control unit (190, 290) may maintain the operation of the drying device (260) if the drying process is to be performed after the end of the washing process. That is, if the control unit (190, 290) is to perform the drying process after the end of the washing process, the control unit (190, 290) may continuously operate the drying device (260) not only when the heating device (250) is operated during the washing process, but also until the end of the drying process.

[0427] According to the present disclosure, the drying process is performed immediately after the end of the washing process, thereby shortening the time required for performing the drying process and saving energy consumed in the operation of the heater (252).

[0428] The control unit (190, 290) can stop the rotation of the mop (160) based on the end of the washing cycle.

[0429] The control unit (190, 290) can raise and lower the mop (160) to the second position based on the end of the washing cycle (1090).

[0430] For example, the control unit (190, 290) can raise the mop (160) to the second position based on the heating device (250) being stopped.

[0431] The control unit (290) can transmit a stop completion signal to the control unit (190) based on the fact that the heating device (250) has stopped, and the control unit (190) can raise and lower the mop (160) to the second position in response to receiving the stop completion signal from the control unit (290).

[0432] The control unit (190) can transmit a lifting completion signal to the control unit (290) in response to the completion of the lifting of the mop (160) to the second position, and the control unit (290) can drive the drying device (260) in response to receiving the lifting completion signal from the control unit (190).

[0433] However, according to various embodiments, the control unit (290) may omit operation 1080 and continuously maintain the operation of the drying device (260).

[0434] Here, the second position may be set to a position higher than the first position. In one embodiment, the second position may be set to a position lower than the position of the mop (160) when the cleaner (10) performs dry cleaning rather than wet cleaning.

[0435] According to the present disclosure, when the heating device (250) is stationary and no longer generates steam, the mop (160) is raised to the second position, thereby preventing steam from being discharged outside the cleaning chamber (230) and moving around the main body (110) of the cleaner (10) and / or to the station (20).

[0436] The control unit (190, 290) can perform a drying process based on the mop (160) being raised to the second position (1100). The drying process is a process of drying the mop (160) with hot air, and the control unit (190, 290) can drive the drying device (260) for the drying process.

[0437] The control unit (190, 290) can perform a drying process by driving the drying device (260) while the mop (160) is positioned at the second position.

[0438] Meanwhile, in order for the mop (160) to dry, air must flow smoothly into the cleaning chamber (230) so that hot air can be evenly delivered to the mop (160).

[0439] FIG. 19 schematically illustrates the flow of air supplied by the drying device of the station while the mop of the vacuum cleaner is positioned in the second position according to one embodiment.

[0440] Referring to FIG. 19, the mop (160) can be spaced from the washing frame (240) while positioned in the second position.

[0441] For example, the mop (160) may be spaced apart from the guide member (240g) (or frame body (240a)).

[0442] By separating the mop (160) from the guide member (240g), the washing chamber (230) can be opened. That is, by separating the mop (160) from the guide member (240g), the washing chamber (230) can have an open portion (cl).

[0443] In one embodiment, the cleaning chamber (230) can be changed into an open chamber by separating the guide member (240g) and the mop (160) while the mop (160) is positioned in the second position.

[0444] When the mop (160) is positioned at the second position, the air flowing through the first flow path (242a) and the second flow path (242b) can all flow toward the chamber floor (230a) and the washing chamber (230) defined by the chamber side wall (230b). However, since the washing chamber (230) is an open space, when the mop (160) is positioned at the second position, the air flowing through the first flow path (242a) and the second flow path (242b) can flow to the outside and inside of the washing chamber (230).

[0445] That is, since the washing chamber (230) is an open space, the air supplied to the washing chamber (230) by the operation of the drying device (260) while the mop (160) is positioned at the second position can flow smoothly in the washing chamber (230).

[0446] According to the present disclosure, by closing the washing chamber (230) in the washing cycle, the external leakage of steam can be minimized, and by opening the washing chamber (230) in the drying cycle, the smooth drying of the mop (160) can be promoted.

[0447] In one embodiment, the control unit (190, 290) may or may not rotate the mop (160) during the drying cycle.

[0448] In one embodiment, the control unit (190, 290) may not rotate the mop (160) because the air supplied to the washing chamber (230) by the operation of the drying device (260) while the mop (160) is positioned at the second position can flow smoothly in the washing chamber (230).

[0449] The control unit (190, 290) can stop the drying device (260) when the drying process is completed.

[0450] The control unit (190, 290) can notify the external device of the end of the drying process through the communication unit (182, 282) based on the end of the drying process.

[0451] The control unit (190, 290) can notify the end of the drying process through the user interface (181, 281) based on the end of the drying process.

[0452] According to the present disclosure, it is possible to prevent steam from being discharged outside the washing chamber (230) during the washing cycle.

[0453] According to the present disclosure, it is possible to prevent water from forming around the main body (110) of the cleaner (10) and / or the station (20) during the washing cycle.

[0454] According to the present disclosure, water that forms around the main body (110) of the cleaner (10) and / or the station (20) during the washing cycle can be immediately removed.

[0455] According to the present disclosure, it is possible to prevent electrical hazards that may occur due to water forming on the charging terminal (151, 218) during the washing cycle.

[0456] A cleaning system according to one embodiment of the present disclosure comprises a cleaner (10) including a main body (110) and a mop (160) provided on the main body (110); And in a station (20) provided to be mounted a cleaner (10), a station (20) including a washing chamber (230) in which a mop (160) is accommodated while the cleaner (10) is mounted on the station (20), a water tank (221), a heating device (250) for supplying steam to the washing chamber (230) by heating water supplied from the water tank (221), and a drying device (260) for blowing air toward the washing chamber (230); wherein the station (20) drives the heating device (250) to supply the steam to the washing chamber (230) based on the start of a washing cycle, and drives the drying device (260) while the steam is being supplied to the washing chamber (230), thereby allowing air to flow to the main body (110) of the cleaner (10).

[0457] The vacuum cleaner (10) can lower the mop (160) to a first position based on the start of the washing cycle, and raise the mop (160) to a second position higher than the first position based on the end of the washing cycle.

[0458] While the mop (160) is positioned at the first position, the air supplied to the washing chamber (230) by the operation of the drying device (260) can flow more to the outside of the washing chamber (230) than to the inside of the washing chamber (230).

[0459] The station (20) may further include a guide member (240g) that divides the air flow path supplied to the washing chamber (230) by the drying device (260) into a first flow path (242a) and a second flow path (242b).

[0460] While the mop (160) is positioned at the first position, the guide member (240g) and the mop (160) come into contact, so that the air flowing through the first flow path (242a) can be directed toward the outside of the washing chamber (230), and the air flowing through the second flow path (242b) can be directed toward the inside of the washing chamber (230).

[0461] While the mop (160) is positioned at the second position, the guide member (240g) and the mop (160) are separated, so that the air flowing through the first flow path (242a) and the second flow path (242b) can flow to the outside and inside of the washing chamber (230).

[0462] While the mop (160) is positioned at the first position, the guide member (240g) and the mop (160) come into contact with each other, so that the washing chamber (230) can be closed by the mop (160).

[0463] The cleaning chamber (230) can be opened by separating the guide member (240g) and the mop (160) while the mop (160) is positioned in the second position.

[0464] The station (20) can perform a drying cycle by stopping the operation of the heating device (250) based on the completion of the washing cycle and operating the drying device (260) while the mop (160) is positioned at the second position.

[0465] The station (20) can drive the heating device (250) in response to the completion of the lowering of the mop (160) to the first position.

[0466] The vacuum cleaner (10) can raise and lower the mop (160) to the second position in response to the operation of the heating device (250) being stopped.

[0467] The vacuum cleaner (10) further includes a suction motor (142), and by driving the suction motor (142) while steam is supplied to the cleaning chamber (230), air drawn into the interior of the main body (110) can flow to the exterior of the main body (110).

[0468] The vacuum cleaner (10) can drive the suction motor (142) at a first intensity while the vacuum cleaner (10) is performing cleaning, and can drive the suction motor (142) at a second intensity that is weaker than the first intensity while the heating device (250) is being driven.

[0469] The cleaner (10) and the station (20) may each include a first sensor (150s) and a second sensor (250s) arranged to face each other while the cleaner (10) is placed on the station (20).

[0470] The vacuum cleaner (10) further includes an exhaust port (112) through which air sucked in by the suction motor (142) is discharged, and the exhaust port (112) can be provided on the lower side of the first sensor (150s).

[0471] When the suction motor (142) is driven, the air discharged through the exhaust port (112) can flow into the space between the first sensor (150s) and the second sensor (250s).

[0472] When the drying device (260) is operated, the air blown toward the washing chamber (230) can flow into the space between the first sensor (150s) and the second sensor (250s).

[0473] A control method of a cleaning system (1) according to one embodiment may include: driving a heating device (250) of a station (20) to supply steam to a washing chamber (230) of a station (20) in which a mop (160) of a cleaner (10) is accommodated based on the start of a washing cycle; and driving a drying device (260) of a station (20) to blow air into the washing chamber (230) while steam is being supplied to the washing chamber (230), thereby allowing air to flow to a main body (110) of the cleaner (10).

[0474] The control method of the cleaning system (1) may further include stopping the operation of the heating device (250) based on the completion of the washing cycle; and performing the drying cycle by operating the drying device (260) while the mop (160) is positioned at the second position.

[0475] Driving the heating device (250) may include driving the heating device (250) in response to the completion of the lowering of the mop (160) to the first position.

[0476] Raising the mop (160) to the second position may include raising the mop (160) to the second position in response to the operation of the heating device (250) being stopped.
