[0056] The above-described station for the robot vacuum cleaner may include a water treatment filter. The water treatment filter may be provided upstream of the heater in the first supply path.

[0057] A robot vacuum cleaner station according to an embodiment of the present invention comprises a main body, a cleaning plate, a first supply channel, and a second supply channel. A cleaning space is provided in the cleaning plate. The robot vacuum cleaner station may comprise a heater. The robot vacuum cleaner station may comprise an integrated channel. The integrated channel communicates with the cleaning space. A cleaning water inlet may be provided in the cleaning plate. The cleaning water inlet communicates with the cleaning space. The end of the first supply channel and the end of the second supply channel may be connected to the integrated channel. The first supply channel and the second supply channel may be connected to the cleaning water inlet. According to an embodiment of the present invention, hot water and / or steam supplied through a first supply channel and water (raw water) supplied through a second supply channel are supplied to a cleaning space through a single integrated channel and can be used to clean objects (e.g., rags), and a robot vacuum cleaner station with a structure that minimizes the parts requiring sealing and is advantageous for preventing leakage is provided.

[0058] A station for a robot vacuum cleaner according to an embodiment of the present invention comprises a gasket. According to an embodiment of the present invention, a passage through which hot water and / or steam and water (raw water) are supplied can be sealed by a single gasket.

[0059] Since steam can not only flow along the passage but also easily diffuse in various directions due to thermal energy, pressure difference, etc., the more parts connecting the passages, the more disadvantageous it may be for steam leakage. However, in the robot vacuum cleaner station according to the embodiment of the present invention, unintended steam leakage can be easily prevented by integrating the passage through which steam travels with the passage through which water (raw water) travels and connecting it to the cleaning plate.

[0060] In a station for a robot vacuum cleaner according to an embodiment of the present invention, hot water and / or steam can be supplied to a cleaning space through a first supply path and raw water can be supplied to a cleaning space through a second supply path, and the supply of hot water (and / or steam) and raw water can be rapidly switched, and the cleaning efficiency of the object to be cleaned can be increased.

[0061] A station for a robot vacuum cleaner according to an embodiment of the present invention may comprise a water treatment filter. Water that has passed through the water treatment filter is supplied to a heater, and the moisture heated by the heater is supplied to a washing space and can be used to wash the mop of the robot vacuum cleaner. By using hot water and steam, the washing efficiency of the mop can be increased, and scale can be prevented from forming in the heater and the water path connected to the heater in the station.

[0062] In a station for a robot vacuum cleaner according to an embodiment of the present invention, the cleaning plate may comprise a cleaning floor surface, a boundary wall, and a cleaning water inlet. The cleaning plate may comprise a first guide wall and a second guide wall. A fluid (water and / or steam) introduced through the cleaning water inlet is contained within the space formed by the cleaning floor surface, the boundary wall, and the bottom surface of the object to be cleaned (e.g., a mop), and the supply of raw water and steam is concentrated toward the object to be cleaned. Even when steam particles diffuse, external leakage is prevented by the boundary wall, and they can be absorbed by the mop located above the cleaning floor surface, thereby preventing the waste of steam.

[0063] In a robot vacuum cleaner station according to an embodiment of the present invention, a fluid (water and / or steam) introduced through a cleaning water inlet can first come into contact with an object to be cleaned or be absorbed by an object to be cleaned (e.g., a mop) between a first guide wall and a second guide wall. Consequently, hot water can be supplied intensively to the mop to effectively perform the soaking and cleaning functions of the mop, and steam can be supplied intensively to the mop to effectively perform the sterilization function of the mop. Furthermore, since the mop of the robot vacuum cleaner coupled to the robot vacuum cleaner station according to an embodiment of the present invention can rotate, soaking, cleaning, and sterilization can be effectively performed over the entire area (surface) of the mop. Additionally, even when steam particles diffuse, external leakage is prevented by the first guide wall and the second guide wall, and the steam can be absorbed by the mop located above the cleaning floor surface. Even when the steam escapes outside the first guide wall and the second guide wall, most of it can be absorbed by the mop, thereby more effectively preventing steam waste.

[0064] In a station for a robot vacuum cleaner according to an embodiment of the present invention, the cleaning plate may comprise a plurality of first protrusions. The first protrusions reduce the movement speed of water or steam moving between a first guide wall and a second guide wall, and help the water or steam moving between the first guide wall and the second guide wall to sufficiently come into contact with the mop or be absorbed by the mop.

[0065] Multiple first protrusions come into contact with the lower part of the mop, creating gaps between the mops, and water or steam entering the cleaning space through these gaps can be absorbed into the mop, effectively soaking, washing, and sterilizing the mop.

[0066] In a robot vacuum cleaner station according to an embodiment of the present invention, the cleaning plate may comprise a plurality of second protrusions. The plurality of second protrusions can contact the lower part of the mop, create gaps between the mops, and scrape the lower side of the mop, and water or steam can be effectively absorbed into the mop in the entire inner area of ​​the boundary wall, thereby improving the cleaning effect and making the soaking, cleaning, and sterilization of the mop more effective.

[0281] The height of the second guide wall (175b) protruding from the washing floor surface (172) can be adjusted to match the bottom surface of the mop (225). The height of the second guide wall (175b) can be determined such that the top of the second guide wall (175b) is in close proximity to or in contact with the bottom surface of the mop (225) at the same distance along the entire lengthwise direction.

[0282] The second guide wall (175b) can be formed in the same way as the first guide wall (175a). The second guide wall (175b) can be symmetrical to the first guide wall (175a) with respect to the second reference line (RL2) passing through the center (170a) of the washing space (171) and the washing water inlet (174).

[0283] In an embodiment of the present invention, the washing floor surface (172) may be divided into a first washing floor surface (172a) and a second washing floor surface (172b).

[0284] The first washing floor surface (172a) is provided between the first guide wall (175a) and the second guide wall (175b).

[0285] The second cleaning floor surface (172b) is provided on the outer side of the first guide wall (175a) and the second guide wall (175b).

[0286] The first washing surface (172a) may be stepped higher than the second washing surface (172b). The height of the first washing surface (172a) may be higher than the height of the second washing surface (172b).

[0287] In an embodiment of the present invention, the washing space (171) may be divided into a first washing space (171a) and a second washing space (171b).

[0288] The first washing space (171a) is the space between the first guide wall (175a) and the second guide wall (175b) within the washing space (171). The second washing space (171b) is the space outside the first guide wall (175a) and the second guide wall (175b) within the washing space (171).

[0289] The second washing space (171b) is larger than the first washing space (171a).

[0290] The first washing space (171a) is directly connected to the washing water inlet (174), and water introduced through the washing water inlet (174) can move to the second washing space (171b) via the first washing space (171a).

[0291] The first washing floor surface (172a) is stepped higher than the second washing floor surface (172b), thereby reducing the vertical height of the first washing space (171a). That is, the distance between the bottom surface of the mop (225) and the first washing floor surface (172a) is kept close, and water or steam introduced into the first washing space (171a) through the washing water inlet (174) can be effectively contacted and absorbed by the mop (225).

[0292] In the station (2) according to an embodiment of the present invention, all or part of the first guide wall (175a) and the second guide wall (175b) may be formed such that the distance between them narrows as they move toward the center of the washing floor surface (172) (the center (170a) of the washing space (171)).

[0293] Accordingly, water or steam in the first washing space (171a) can be prevented from easily escaping into the second washing space (171b), and water or steam introduced into the washing space (171) through the washing water inlet (174) can be effectively and quickly contacted and absorbed by the mop (225) in the first washing space (171a) without delay.

[0294] As described above, the fluid (water and / or steam) introduced into the washing water inlet (174) can first come into contact with the mop (225) or be absorbed by the mop (225) between the first guide wall (175a) and the second guide wall (175b), so that the soaking and washing functions of the mop (225) can be effectively achieved by supplying hot water intensively to the mop (225), and the sterilization function of the mop (225) can be effectively achieved by supplying steam intensively to the mop (225).

[0295] Since the mop (225) of the robot vacuum cleaner (3) coupled to the station (2) can rotate around the rotation axis (220a), soaking, washing, and sterilization can be effectively performed over all areas (surfaces) of the mop (225), and even when steam particles spread, external leakage is prevented by the first guide wall (175a) and the second guide wall (175b) and can be absorbed by the mop (225) located above the washing floor surface (172), and even when steam escapes outside the first guide wall (175a) and the second guide wall (175b), most of it can be absorbed by the mop (225), and waste of steam can be effectively prevented.
