[0244] A second air pump (156) and a check valve (157) may be connected to the wastewater tank (152). The second air pump (156) can cause positive pressure to be applied inside the wastewater tank (152), and accordingly, the fluid inside the wastewater tank (152) can move to the outside of the station (2) through the check valve (157).

[0245] In an embodiment of the present invention, the water treatment filter (135) may be located to the left or right of the entrance (102) of the station (2).

[0246] A water treatment filter (135) may be provided adjacent to the left or right side of the main door (104). The water treatment filter (135) may be located on the left or right side of the main door (104).

[0247] As described above, the station (2) includes a dust bag drawer (120) configured to allow dust from a robot vacuum cleaner (3) placed on a seating portion (110) to be introduced, and the dust bag drawer (120) may be located on the opposite side of the water treatment filter (135) with respect to the entrance (102) and the seating portion (110).

[0248] By providing a water treatment filter (135) on the left or right side of the main door (104), the increase in the vertical height of the station (2) due to the provision of the water treatment filter (135) can be prevented.

[0249] FIGS. 5a and FIGS. 5b are schematic diagrams illustrating the flow of water and air in a station (2) for a robot vacuum cleaner according to one embodiment of the present invention.

[0250] A station (2) according to an embodiment of the present invention may be formed to include a blower passage (161) and a blower fan (162).

[0251] A station (2) according to an embodiment of the present invention may comprise a blower passage (161), a second heater (163), and a blower fan (162).

[0252] The airflow path (161) forms a path through which air moves toward the injection area (115).

[0253] The blower fan (162) generates a flow of air in the blower passage (161) and causes the air to move toward the spray area (115). The air supplied to the spray area (115) by the blower fan (162) can be sprayed toward the rag (225), thereby allowing the rag (225) to be dried.

[0254] As illustrated in FIG. 5a, when a second heater (163) is provided, the second heater (163) may be provided on the air passage (161). That is, air heated by the second heater (163) may move through the air passage (161). The heated air supplied to the spray area (115) may be sprayed toward the mop (225), thereby allowing hot air drying of the mop (225) by the heated air and drying and sterilization of the mop (225).

[0255] As shown in FIG. 5b, the airflow path (161) may be configured to pass through a heater (137). In this case, a second heater (163) may not be provided.

[0256] As shown in FIG. 5b, the air in the air passage (161) is heated as the heater (137) is operated and heated, and the heated air can be supplied to the spray area (115) by the blower fan (162). The heated air supplied to the spray area (115) can be sprayed toward the mop (225), and accordingly, hot air drying of the mop (225) by the heated air can be achieved, and drying and sterilization of the mop (225) can be achieved.

[0257] FIG. 6 is a diagram showing a control method for a robot vacuum cleaner station (2) according to an embodiment of the present invention. In FIG. 6, each step proceeds from left to right.

[0258] FIG. 7 is a graph showing the relationship between the flow rate, the power of the heater (137), and the temperature change. The graph in FIG. 7 is based on the heat capacity calculation formula (Q=cmΔt), where the specific heat (c) is assumed to be 4.18 J / g℃ and the efficiency is assumed to be 100%.

[0259] A robot vacuum cleaner station (2) according to an embodiment of the present invention can be operated such that a first step (S10), a second step (S21, S22), a third step (S30), and a fourth step (S50) are performed sequentially.

[0260] The first step (S10) is a step in which the raw water inlet (132a) and the first outlet (132b) are connected, the flow control valve (136) is opened to a first level, and the heater (137) is operated.

[0261] The second step (S21, S22) above is a step in which the raw water inlet (132a) and the second outlet (132c) are connected.

[0262] The above third step (S30) is a step in which the raw water inlet (132a) and the first outlet (132b) are connected, the flow control valve (136) is opened to a second level smaller than the first level, and the heater (137) is operated.

[0263] The above fourth step (S50) is a step in which the raw water inlet (132a) and the first outlet (132b) are connected, the flow control valve (136) is opened to a third level smaller than the second level, and the heater (137) is operated.

[0264] As shown in Fig. 7, as the flow rate increases, the slope of the temperature change (vertical axis) decreases.

[0265] Referring to FIG. 7, when the initial temperature of the raw water supplied to the flow path is 20°C, the flow rate of the water in the flow path is 4.5 g / s, and the power of the heater (137) is 900 Watts, there is a temperature increase of about 50°C, and accordingly, the temperature of the water in the flow path is heated to about 70°C.

[0266] When the initial temperature of the raw water supplied to the flow path is 20°C, the flow rate of the water in the flow path is 3.0 g / s, and the power of the heater (137) is 900 Watts, there is a temperature increase of about 72°C, and accordingly, the temperature of the water in the flow path is heated to about 92°C.

[0267] When the initial temperature of the raw water supplied to the Euro is 20℃, the flow rate of the water in the Euro is 1.0g / s, and the power of the heater (137) is 900Watt, there is a temperature increase of 100℃ or more, and accordingly, the water from the Euro can be sprayed and transformed into steam and supplied.

[0268] In this way, by setting the power of the heater (137) and controlling the flow rate of water, the required temperature of the hot water can be controlled, and furthermore, the amount of steam required can be controlled by heating the water.

[0269] In the station (2) according to the embodiment of the present invention, the flow rate of water moving through the first supply path (133) is controlled through the flow rate control valve (136) to control the flow rate of water heated by the heater (137), and accordingly, the temperature of the hot water can be controlled and the amount of steam can also be controlled.

[0270] In the first step (S10), water moves through the first supply channel (133), at which time the flow control valve (136) is opened to a first level and the heater (137) is operated, and the water moving through the first supply channel (133) is heated to a predetermined temperature. In the first step (S10), the water is heated and can be supplied to the spray area (115) at 40 to 80°C.

[0271] In the first step (S10), heated water is supplied to the rag (225), thereby allowing the rag (225) to be soaked.

[0272] In the second stage (S21, S22), water moves through the second supply channel (134) and can be supplied to the spray area (115) as raw water without being heated by the heater (137). In the second stage (S21, S22), detergent can be supplied together toward the spray area (115).

[0273] The second stage (S21, S22) can be divided into the second-1 stage (S21) and the second-2 stage (S22).

[0274] In step 2-1 (S21), water is supplied to the mop (225), and foreign matter on the mop (225) can be removed.

[0275] In step 2-2 (S22), water is supplied to the mop (225), and the mop (225) can be rinsed.

[0276] The third stage (S30) is a stage in which water moves through the first supply channel (133), the flow control valve (136) opens to a second level smaller than the first level, and the heater (137) operates. Since the flow rate when the flow control valve (136) opens to the second level in the third stage (S30) is smaller than the flow rate when the flow control valve (136) opens to the first level in the first stage (S10), the flow rate supplied to the heater (137) is also smaller, so the temperature of the water in the third stage (S30) is higher than the temperature of the water in the first stage (S10). In the third stage (S30), the water is heated and can be supplied to the spray area (115) at 70 to 100°C.

[0277] In the third step (S30), high-temperature hot water may be supplied to the mop (225), and steam may also be supplied to the mop (225). In the third step (S30), sterilization of the mop (225) may be performed.

[0278] The fourth stage (S50) is a stage in which water moves through the first supply channel (133), the flow control valve (136) opens to a third level smaller than the second level, and the heater (137) operates. Since the flow rate when the flow control valve (136) opens to the third level in the fourth stage (S50) is smaller than the flow rate when the flow control valve (136) opens to the second level in the third stage (S30), the flow rate supplied to the heater (137) is also smaller, so the temperature of the water in the fourth stage (S50) is higher than the temperature of the water in the third stage (S30), or the water heated in the fourth stage (S50) can be transformed into steam. In the fourth stage (S50), the water is heated and can be supplied to the injection area (115) in the form of steam.

[0279] In step 4 (S50), steam can be supplied to the mop (225). In step 4 (S50), odor removal of the mop (225) can be performed.

[0280] The robot vacuum cleaner station (2) according to an embodiment of the present invention can be operated to perform the fifth step (S40) and the sixth step (S60).

[0281] Step 5 (S40) can be performed between Step 3 (S30) and Step 4 (S50).

[0282] In the fifth step (S40), heated air can be supplied to the spray area (115) through the air blower (161), and the heated air can be sprayed onto the mop (225). In the fifth step (S40), the mop (225) can be sterilized by the heated air.

[0283] Step 6 (S60) can be performed after Step 4 (S50).

[0284] In step 6 (S60), unheated air can be supplied to the spray area (115) through the air blower (161), and the air can be sprayed onto the rag (225). In step 6 (S60), drying of the rag (225) can be achieved by the air.
