Description

Robot vacuum cleaner station and frame for robot vacuum cleaner station

[0001] The present invention relates to a robot vacuum cleaner station, and more specifically, to a built-in robot vacuum cleaner station that, when combined with a robot vacuum cleaner, can collect dust from the dustbin of the robot vacuum cleaner, wash the mop of the robot vacuum cleaner, and dry the mop.

[0002]

[0003] With the recent advancement of industrial technology, robotic vacuum cleaners are being developed that can autonomously drive and clean areas requiring cleaning without user intervention.

[0004] Such a robot vacuum cleaner is equipped with a sensor capable of recognizing the space to be cleaned, an agitator capable of sweeping the floor surface, and a mop capable of wiping the floor surface, and can drive while sucking up dust from the floor surface of the space recognized by the sensor and wiping with the mop.

[0005] Among robot vacuum cleaners, there are dry robot vacuum cleaners capable of sucking up and removing debris scattered on the floor surface, and wet robot vacuum cleaners capable of wiping the floor surface with a mop containing moisture to effectively remove debris attached to the floor surface. Dry robot vacuum cleaners are equipped with a dust bin and suck up debris from the floor surface using the suction power of a suction motor. Wet robot vacuum cleaners are equipped with a water tank, and water contained in the tank is supplied to the mop so that the mop, while containing moisture, wipes the floor surface to effectively remove debris attached to the floor surface. In addition, there are robot vacuum cleaners equipped with both an agitator and a mop.

[0006] The charging dock of a robot vacuum is a device into which a robot vacuum is docked after cleaning, and which supplies power to the battery equipped in the robot vacuum to charge it. The charging dock is equipped with an internal power supply module. The charging dock is equipped with a charging terminal connected to the power supply module, and the robot vacuum is equipped with a corresponding terminal. When the charging terminal and the corresponding terminal come into contact, power is supplied to the battery to charge it.

[0007] Meanwhile, if a robot vacuum cleaner charging dock is placed indoors, it occupies a certain portion of the space. In this case, indoor space efficiency may suffer. Furthermore, problems may arise where users or pets collide with the robot vacuum cleaner while passing by, resulting in injury to the user or pet as well as damage to the robot vacuum.

[0008] In addition, in the case of stations equipped with a dust collection function, there is a limitation in that the increased volume occupied can detract from the interior design.

[0009] Meanwhile, Chinese Utility Model Registration CN 218922468 U discloses a cleaning station in which a robot vacuum cleaner is combined with the lower side of a washing machine to charge the robot vacuum cleaner, collect dust, and clean the mop of the robot vacuum cleaner.

[0010] However, the above vacuum cleaner station has an open space formed below the washing machine through which a robot vacuum can enter, a detergent and water supply device for washing the mop is provided vertically above the space through which the robot vacuum enters, and a dust bag is placed on the side of the space through which the robot vacuum enters.

[0011] In this type of arrangement, the overall height of the vacuum cleaner station increases, which limits its ability to be mounted using the space underneath furniture, including the sink.

[0012] In addition, since the above vacuum cleaner station must be installed below the washing machine, space for installing the washing machine must be provided, and there is a limitation in that an installation space must be provided with a height exceeding that of the washing machine itself, taking into account the height of the vacuum cleaner station as well.

[0013] Meanwhile, generally, kitchen cabinets are supported by pedestals. Pedestals can be attached to the lower plate of the kitchen cabinet to support the lower plate. In this case, two pedestals can be attached to the front and two to the rear of the lower plate of the kitchen cabinet. Through this, the pedestals can stably support the kitchen cabinet.

[0014] However, if the gap between the pedestals is narrow, it is difficult to slide the robot vacuum cleaner station under the kitchen cabinet, and there is a limitation that four pedestals must be removed to install the robot vacuum cleaner station.

[0015] In addition, if the four pedestals are removed, there is a limitation in that the kitchen cabinet cannot be supported and sinks downward.

[0016]

[0017] The present invention was created to improve upon the problems of conventional robot vacuum cleaner stations as described above, and aims to provide a robot vacuum cleaner station that can be built into the lower side of a kitchen cabinet without requiring a separate installation space.

[0018] In addition, the purpose is to provide a robot vacuum cleaner station capable of accommodating a robot vacuum cleaner in the lower space of a kitchen cabinet having a predetermined height limit.

[0019] In addition, the purpose is to provide a robot vacuum cleaner station that can automatically collect dust inside the dustbin of the robot vacuum cleaner when combined with it.

[0020] In addition, the purpose is to provide a robot vacuum cleaner station that can be easily pushed under a kitchen cabinet after pre-connecting hoses or wires during installation.

[0021] In addition, the purpose is to provide a robot vacuum cleaner station that can be installed without removing the rear pedestal, which is difficult for a worker to reach.

[0022]

[0023] To achieve the above-mentioned purpose, a robot vacuum cleaner station according to the present invention comprises: a frame; and a housing that accommodates a robot vacuum cleaner inside and is retractably coupled to the frame; wherein the frame comprises a pair of side walls facing each other; and the housing may be positioned between the pair of side walls.

[0024] At this time, the frame may further include a frame connecting part that connects the lower ends of the pair of side walls and is positioned to face the ground.

[0025] At this time, the width of the frame connection part of the frame may be greater than the height of each of the side walls.

[0026] Meanwhile, the above frame may further include an upper lifter that is movably connected to each of the pair of side walls.

[0027] In addition, the frame may further include an inner frame coupled to the inner surface of each of the pair of side walls.

[0028] At this time, the frame may have a guide portion formed therein to guide the movement of the housing.

[0029] In addition, the above frame may further include a plurality of lower lifters that are connected to the lower side of each of the above side walls and come into contact with the ground.

[0030] At this time, more lower lifters than upper lifters can be coupled to the side wall.

[0031] Meanwhile, the housing may include a front housing having an entrance through which the robot vacuum cleaner passes; and a rear housing extending rearward from the front housing and formed to be narrower than the front housing.

[0032] At this time, the front housing is positioned between the pair of side walls and can be coupled to the side walls so as to be movable relative to them.

[0033] In addition, the rear housing may be provided with a power connection part to which an external power source is connected.

[0034] Meanwhile, the gap between the pair of upper lifters may be larger than the width of the rear housing.

[0035] Meanwhile, the above housing may further include a housing body in which the robot vacuum cleaner is stored; and an upper cover that covers the upper side of the housing body.

[0036] At this time, the upper cover can be attached to and detached from the housing body along a direction that intersects with the direction in which the housing body is withdrawn from the frame.

[0037] At this time, the length of the front-rear direction of the frame may be shorter than the length of the front-rear direction of the housing.

[0038] Meanwhile, the above frame may have a height greater than 0mm and less than or equal to 200mm.

[0039] Meanwhile, in order to achieve the above-mentioned purpose, a method for installing a robot vacuum cleaner station according to the present invention comprises the steps of: placing a frame on the lower side of a kitchen cabinet; and slidingly coupling a housing of the robot vacuum cleaner station to the frame.

[0040]

[0041] As explained above, according to the robot vacuum cleaner station of the present invention, a module capable of charging the robot vacuum cleaner, collecting dust, and washing the mop is arranged along a horizontal direction with respect to the robot vacuum cleaner, thereby providing the effect of utilizing the lower space of the kitchen cabinet.

[0042] In addition, the charging port, dust collection unit, mop washing unit, and mop drying unit are arranged around the robot vacuum cleaner, which has the effect of enabling the robot vacuum cleaner to perform various functions simultaneously.

[0043] In addition, since the sides other than the front are concealed by the kitchen cabinets, it has the effect of providing the user with an aesthetic sense in terms of interior design.

[0044] In addition, by removing the pedestal of the kitchen cabinet and installing a robot vacuum cleaner station in that space, the space underneath the cabinet can be utilized effectively.

[0045] In addition, by making the width of the rear part of the housing narrower than the front part, the robot vacuum cleaner station can be installed by sliding it in without removing the rear pedestal, which is difficult for a worker to reach.

[0046] In addition, by first installing the frame on the lower side of the kitchen cabinet and using a lifter to support the lower surface of the kitchen cabinet, it is possible to prevent the kitchen cabinet from sinking downwards.

[0047] In addition, it has the effect of being installable through a simple process of connecting hoses and wires to the rear of the housing while it is pulled out, and then pushing it into the frame.

[0048] In addition, when inspection or repair is required, the housing can be removed from the frame and only the top cover needs to be lifted, which has the effect of making replacement and repair of parts easy.

[0109]

[0110] robot vacuum cleaner

[0111]

[0112] Meanwhile, FIGS. 5 to 8 disclose drawings for explaining a robot vacuum cleaner in a robot vacuum cleaner system according to an embodiment of the present invention.

[0113] Referring to FIGS. 5 to 8, the structure of the robot vacuum cleaner (200) is described as follows.

[0114] The robot vacuum cleaner (200) can automatically clean the area to be cleaned by driving itself through the area to be cleaned and sucking up foreign substances such as dust from the floor.

[0115] A robot vacuum cleaner (200) according to an embodiment of the present invention is configured to be placed on a floor and move along the floor surface to clean the floor. Accordingly, the following description will define the up and down directions based on the state in which the robot vacuum cleaner (200) is placed on the floor.

[0116] And based on a pair of wheels (260), the side where the auxiliary wheel (270) to be described later is positioned is designated as the front, and the side where the rotating cleaner (240) to be described later is positioned is designated as the rear.

[0117] The 'lowest part' of each component described in the embodiment of the present invention may be the part located lowest in each component when the robot vacuum cleaner (200) according to the embodiment of the present invention is placed on the floor for use, or the part closest to the floor.

[0118] A robot vacuum cleaner (200) according to an embodiment of the present invention comprises a body (210), a dust bin (220), a water tank (230), a rotating cleaning unit (240), an agitator (250), a wheel (260), an auxiliary wheel (270), and a charging terminal (280).

[0119] The body (210) can form the overall shape of the robot vacuum cleaner (200). Each component forming the robot vacuum cleaner (200) can be combined with the body (210), and some components forming the robot vacuum cleaner (200) can be accommodated inside the body (210).

[0120] Specifically, the body (210) may be equipped with parts of the robot vacuum cleaner (200) in its internal space. For example, the body (210) may accommodate a battery and at least one motor in its internal space.

[0121] In an embodiment of the present invention, the body (210) may be formed in a shape where the width (or diameter) in the horizontal direction is greater than the height in the vertical direction. Such a body (210) helps the robot vacuum cleaner (200) form a stable structure and can provide a structure advantageous for avoiding obstacles while the robot vacuum cleaner (200) moves (drives).

[0122] When viewed from above or below, the body (210) can be made in various shapes, such as circular, elliptical, or square.

[0123] The body (210) can be configured by dividing it into a lower body and an upper body, and the lower body and the upper body can be combined to form a space inside.

[0124] The lower body can be combined with the upper body to form a space capable of accommodating a battery, at least one sensor, and at least one motor inside.

[0125] In the lower body, an intake part (211) into which air is introduced and a hole for accommodating a pair of wheels (260) may be formed.

[0126] The suction part (211) may be a passage through which dust from the bottom surface is introduced. Additionally, the suction part (211) may be in communication with a suction passage (not shown) formed inside the body (210), and the suction passage may be in communication with the internal space of the dust container (220).

[0127] Meanwhile, the lower body may be further provided with an exhaust passage. One side of the exhaust passage may be in communication with the internal space of the dust bin (220), and the other side may be in communication with the exhaust port. At this time, a filter may be placed in the exhaust port.

[0128] With this configuration, air introduced through the intake section (211) flows into the dust bin (220) through the intake path and can be discharged to the exhaust port through the exhaust path.

[0129] An agitator (250), to be described later, can be rotatably accommodated in the suction part (211). With this configuration, dust around the suction part (211) can be guided into the suction part (211) by the rotation of the agitator (250), and the efficiency of dust suction can be increased.

[0130] The upper body can form the upper exterior of the robot vacuum cleaner (200). Although not illustrated, the upper body may be equipped with a display.

[0131] The robot vacuum cleaner (200) of the present invention may include a bumper. The bumper is formed to be attached along the edge of the body (210) and to move relative to the body (210).

[0132] The bumper may be attached along a portion of the edge of the body (210) or along the entire edge of the body (210). At least one elastic member (not shown) may be provided between the bumper and the body (210). With this configuration, when the bumper comes into contact with an obstacle or the like and moves relative to the center of the body (210), the bumper can return to its original position by the restoring force of the elastic member (not shown), and can absorb or disperse the impact applied to the bumper, thereby preventing and reducing the transmission of impact to the body (210).

[0133] The dustbin (220) may be equipped to suck in external dust and air and store dust.

[0134] The dust container (220) can store dust that enters through the suction path. The dust container (220) may have a dust inlet that communicates with the suction path, an internal space for storing dust, and an air outlet for discharging air.

[0135] The dustbin (220) may be provided inside the body (210). At this time, the dustbin (220) may be fixedly connected to the body (210) or, depending on the embodiment, may be provided so as to be detachable.

[0136] Meanwhile, in the present invention, a dust discharge channel may be formed in the dust bin (220). The dust discharge channel may connect the internal space of the dust bin (220) with the external space of the robot vacuum cleaner (200). With such a configuration, when dust is collected through the robot vacuum cleaner station (100), the dust inside the dust bin (220) can be removed.

[0137] Meanwhile, a dust outlet (221) communicating with the dust discharge path may be formed in the dust container (220) according to an embodiment of the present invention. For example, the dust outlet (221) may be formed on one side of the rear of the outer surface (or outer circumference) of the body (210). For another example, the dust outlet (221) may be formed on the outer surface of the dust container (220).

[0138] Additionally, the robot vacuum cleaner (200) according to an embodiment of the present invention may be provided with a dust bin door (222) capable of selectively opening and closing the dust discharge port (221). Specifically, the dust bin door (222) may be coupled to the body (210) and positioned to block the dust discharge port (221). For example, the dust bin door (222) may be formed of a rubber or resin material and configured to be flip-floppy, with one side fixedly coupled to the body (210).

[0139] With this configuration, when the dust collection motor (145) of the robot vacuum cleaner station (100) described later is operated, the dust bin door (222) is elastically deformed by the driving force of the dust collection motor (145), and the dust discharge port (221) is opened so that dust inside the dust bin (220) can be collected into the dust collection unit (140) of the robot vacuum cleaner station (100).

[0140] The water container (230) is formed in the shape of a container having an internal space for storing a liquid such as water. The water container (230) is placed inside the body (210), and may be fixedly connected to the body (210) or detachably connected to the body (210).

[0141] The water tank (230) includes a supply unit (231) and a nozzle (not shown). The supply unit (231) may be provided to supply a liquid, such as water, from the outside. For example, the supply unit (231) may have an inlet formed on the rear side of the outer surface (or outer circumference) of the body (210) and may be connected to a storage space inside the water tank (230) through a water supply hose.

[0142] At this time, the supply unit (231) may be positioned on the opposite side of the left and right direction of the robot vacuum cleaner (200) in relation to the dust outlet (221). For example, if the dust outlet (221) is positioned on the rear left side of the body (210), the supply unit (231) may be positioned on the rear right side of the body (210).

[0143] Through this configuration, the robot vacuum cleaner (200) is coupled to the robot vacuum cleaner station (100), and the robot vacuum cleaner station (100) can simultaneously perform dust collection and water injection.

[0144] Meanwhile, the nozzle (not shown) is formed in the shape of a tube or pipe and is connected to the water tank (230) so that the liquid inside the water tank (230) can flow through it. One end of the nozzle (not shown) is connected to the water tank (230), and the other end is positioned so as to be located on the upper side or on the rotating plate of a pair of rotating plates (241), respectively, thereby allowing the liquid inside the water tank (230) to be supplied to a pair of rags (242) respectively.

[0145] That is, the nozzle (not shown) may be formed in a shape where one tube is branched into two, and in this case, one of the branched ends may be located on the upper side of the left mop, and the other branched end may be located on the upper side of the right mop.

[0146] Meanwhile, although not shown, the water tank (230) is equipped with a pump to allow water inside the water tank (230) to flow through a nozzle (not shown). Therefore, when the pump of the water tank (230) is operated, the liquid stored inside the water tank (230) can be discharged to a rotating cleaner (240) through a nozzle (not shown).

[0147] The rotating cleaning unit (240) includes a rotating plate (241) and a mop (242).

[0148] The rotating plate (241) may be provided as a pair including a left rotating plate and a right rotating plate, and the mop (242) may be provided as a pair including a left mop and a right mop.

[0149] The rotating plate (241) can be rotatably positioned on the bottom surface of the body (210), and the mop (242) can be attached to the lower side.

[0150] The rotating plate (241) is formed to have a predetermined area and is formed in the shape of a flat plate or a flat frame. This rotating plate (241) is generally laid horizontally, and accordingly, is formed in a shape where the width (or diameter) in the horizontal direction is sufficiently larger than the height in the vertical direction. The rotating plate (241) attached to the body (210) may be parallel to the bottom surface or may be inclined with respect to the bottom surface. The rotating plate (241) may be formed in the shape of a circular plate, the bottom surface of the rotating plate (241) may generally be circular, and the rotating plate (241) may be formed in a rotationally symmetrical shape overall.

[0151] A pair of rotating plates (241) can be symmetrical to each other.

[0152] The mop (242) can be attached to the lower side of the rotating plate (241) so as to face the floor.

[0153] The mop (242) is formed such that the bottom surface facing the floor has a predetermined area, and the mop (242) is formed in a flat shape. The mop (242) is formed such that the width (or diameter) in the horizontal direction is sufficiently larger than the height in the vertical direction. When the mop (242) is attached to the body (210), the bottom surface of the mop (242) may be parallel to the floor or may be inclined with respect to the floor.

[0154] The bottom surface of the mop (242) can generally be circular, and the mop (242) can be formed in a rotationally symmetrical shape overall. Additionally, the mop (242) can be attached to the bottom surface of the rotating plate (241) and can be coupled to the rotating plate (241) to rotate together with the rotating plate (241).

[0155] Meanwhile, although not shown, the rotating cleaning unit (240) may be equipped with a driving unit that applies rotational force to the rotating plate (241). For example, the driving unit may be equipped with a motor and at least one gear. Thus, when the driving unit is operated, the rotating plate (241) and the mop (242) rotate to wipe and clean the floor surface.

[0156] The agitator (250) is rotatably equipped with a plurality of brushes to guide external dust and air into the dust bin (220). At this time, the agitator (250) may be equipped with at least one gear.

[0157] Meanwhile, the agitator (250) according to the present embodiment may receive rotational power by having a separate agitator motor (not shown) installed, and may also receive rotational power from a driving motor according to the embodiment, and may also receive rotational power from the driving unit of the rotating cleaning unit (240).

[0158] The wheel (260) may be provided on the bottom surface of the body (210) and may be connected to a driving unit (not shown). At this time, the driving unit (not shown) may be coupled to the body (210).

[0159] The wheel (260) is provided on the body (210) and can roll on the floor.

[0160] The wheel (260) may be composed of a first driving wheel and a second driving wheel. In this case, the first driving wheel may be formed identically to the second driving wheel, or may be formed symmetrically. For example, if the first driving wheel is located on the left side of the robot vacuum cleaner (200), the second driving wheel may be located on the right side of the robot vacuum cleaner (200), and in this case, the first driving wheel and the second driving wheel may be symmetrical to each other.

[0161] The drive unit (not shown) may be comprised of a driving motor and a gear. In this case, the driving motor is housed inside the body (210) and can provide power to the wheel (260). The driving motor may include a first driving motor and a second driving motor.

[0162] The driving motor may be an electric motor. Multiple gears are configured to mesh and rotate with each other, connecting the driving motor and the wheel (260) and transmitting the rotational power of the driving motor to the wheel (260). Therefore, the wheel (260) can rotate when the rotation axis of the driving motor rotates.

[0163] With this configuration, when the driving motor is operated, the wheel (260) rotates and the body (210) can travel on the floor at a predetermined driving speed.

[0164] The auxiliary wheel (270) is provided on the lower side of the body (210) and can roll on the floor surface (surface to be cleaned). The auxiliary wheel (270) can support the body (210) on the floor surface together with a pair of wheels (260). With this configuration, the auxiliary wheel (270) can guide the movement of the robot vacuum cleaner (200) while minimizing friction between the robot vacuum cleaner (200) and the floor surface.

[0165] A suction motor (not shown) can generate a suction force capable of sucking in external dust and air through the suction section (211). For example, the suction motor (not shown) may be an electric motor. External dust and air can be drawn into the suction section (211) by the suction force generated by the suction motor (not shown), and after passing through the suction path, can reach the dust bin (220).

[0166] Although not illustrated, the battery is configured to be coupled to the body (210) and to supply power to other components forming the robot vacuum cleaner (200). The battery can supply power to at least one motor equipped in the robot vacuum cleaner (200). For example, the battery can supply power to the motors equipped in the rotary cleaner (240), the agitator (250), the wheel (260), and the suction motor (not illustrated).

[0167] In addition, the battery can supply power to the sensor unit (not shown) and the control unit (not shown).

[0168] The battery can be charged by an external power source, and for this purpose, a charging terminal (280) for charging may be provided on one side of the body (210). For example, the charging terminal (280) may be positioned on the rear side of the outer surface of the body (210). When the robot vacuum cleaner (200) is connected to the robot vacuum cleaner station (100), the charging terminal (280) can come into contact with the power supply terminal (123b) of the robot vacuum cleaner station (100) to receive power.

[0170] Robot vacuum cleaner station

[0171]

[0172] FIG. 9 shows a perspective view illustrating the structure of a robot vacuum cleaner station according to an embodiment of the present invention. FIG. 10 shows a perspective view illustrating the door portion of a robot vacuum cleaner station according to an embodiment of the present invention. FIG. 11 shows a perspective view illustrating the internal structure of a robot vacuum cleaner station according to an embodiment of the present invention.

[0173] Referring to FIGS. 3 to 11, the robot vacuum cleaner station (100) of the present invention is described as follows.

[0174] A robot vacuum cleaner (200) can be accommodated in the robot vacuum cleaner station (100). A robot vacuum cleaner (200) can be attached to the mounting portion (120) of the robot vacuum cleaner station (100).

[0175] The robot vacuum cleaner station (100) may include a housing (110).

[0176] The housing (110) can form the exterior of the robot vacuum cleaner station (100). For example, the housing (110) can be formed in a shape similar to a cuboid including at least one outer wall surface.

[0177] The housing (110) of the present invention can be pulled out and coupled to the frame (400). That is, the housing (110) can be movably coupled between a pair of side walls (410).

[0178] The housing (110) may have a space formed therein to accommodate a seating portion (120), a door portion (130), a dust collection portion (140), a mop washing portion (160), and a mop drying portion (170).

[0179] The housing (110) can be mounted on the lower side of the kitchen cabinet (2). Specifically, the housing (110) can be installed in a mounting space formed between the lower plate (23) of the kitchen cabinet (2) and the floor of the kitchen.

[0180] Meanwhile, the housing (110) includes a housing body (111) that is retractably coupled to a pair of side walls (410). A robot vacuum cleaner (200) can be stored inside the housing body (111).

[0181] Meanwhile, the front width of the housing body (111) is greater than the rear width. Specifically, the housing body (111) may be formed to include a front housing (111a) and a rear housing (111b) along the front-rear direction. At this time, the rear housing (111b) is formed to extend rearward from the front housing (111a) and may be formed to be narrower than the front housing (111a).

[0182] Here, "front" may refer to the direction in which the door (131) is provided relative to the interior of the robot vacuum cleaner station (100).

[0183] Additionally, the rear may refer to the opposite direction from the front relative to the interior of the robot vacuum cleaner station (100). For example, a wall of a building (not shown) may be placed at the rear of the robot vacuum cleaner station (100).

[0184] In addition, when looking forward from inside the robot vacuum cleaner station (100), the left side can be called the left side and the right side the right side.

[0185] Meanwhile, the front housing (111a) and the rear housing (111b) can be distinguished based on the width in the left-right direction. That is, the rear housing (111b) may refer to the part of the front housing (111a) where the width in the left-right direction is reduced.

[0186] The front housing (111a) is positioned between a pair of side walls (410) and can be coupled to the side walls (410) so as to be movable relative to them. An entrance (127) through which a robot vacuum cleaner (200) passes can be formed in the front housing (111a). At this time, the front housing (111a) can be formed to have a width corresponding to the width of the space between the pair of side walls (410). The left and right sides of the front housing (111a) can be formed parallel to each other with a predetermined width. For example, the width of the front housing (111a) can be equal to or slightly smaller than the width of the space between the pair of side walls (410). Through this, the front housing (111a) can be pulled out and pulled in between the pair of side walls (410).

[0187] Meanwhile, the rear housing (111b) may be formed to have a smaller width than the front housing (111a).

[0188] Specifically, the rear housing (111b) is formed to extend rearward from the front housing (111a) and includes a width change section formed to gradually narrow in width from the rear end of the front housing (111a).

[0189] At this time, the width change portion may be formed by being bent inward in the left-right direction from the rear end of the front housing (111a) and extending into a curved shape. For example, the width change portion may be formed into a curved shape that is concavely sunken inward in the left-right direction from the rear end of the front housing (111a).

[0190] Additionally, the rear housing (111b) is formed extending from the rear end of the width change section and includes rear extension sections formed parallel to each other with a predetermined width. At this time, the width of the rear extension sections is formed to be smaller than the width of the front housing (111a).

[0191] Additionally, the width of the rear housing (111b) may be smaller than the gap between a pair of upper lifters (430). At this time, the width of the rear housing (111b) may be larger than the width of the seating portion (120).

[0192] Meanwhile, the rear housing (111b) may be provided with a power connection part (111ba) to which an external power source is connected and at least one fitting part (111bb, 111bc) to which a hose is connected.

[0193] The front housing (111a) is provided to be movable relative to the side walls (410). For example, the front housing (111a) may be positioned to face a pair of side walls (410).

[0194] At this time, the front housing (111a) may be positioned inside the robot vacuum cleaner station (100) rather than the pair of side walls (410). That is, the front housing (111a) may be positioned closer to the seating portion (120) than the pair of side walls (410).

[0195] The housing body (111) includes a guide portion (111c). For example, the guide portion (111c) of the housing body (111) may be a guide rail.

[0196] The guide portion (111c) is positioned on the front housing (111a) and can guide the movement of the front housing (111a). The guide portion (111c) may be fixedly coupled to the front housing (111a) or formed integrally, and may be coupled to the guide portion (451) installed on the side wall (410) to guide the movement path of the front housing (111a). Meanwhile, although it is described in the present invention that the guide portion (111c) of the housing body (111) is provided with a rail, it is not necessarily limited to the form of a rail, and may include all forms such as a roller, guide groove, or guide rib that can replace the rail.

[0197] Meanwhile, the housing (110) further includes a floor surface (not shown) facing the kitchen floor, and the front housing (111a) can be connected through the floor surface (not shown).

[0198] Meanwhile, the housing (110) may further include an upper cover (113) facing the lower plate (23) of the kitchen cabinet (2). The upper cover (113) is positioned to face the lower surface of the kitchen cabinet (2) and can cover the upper side of the housing body (111). The upper cover (113) can be detachably coupled to the upper end of the housing body (111). Thus, even if foreign matter falls downward from the kitchen cabinet (2), it is possible to prevent the components of the robot vacuum cleaner (200) and the robot vacuum cleaner station (100) from being contaminated.

[0199] Additionally, the upper cover (113) may be formed in a shape where two or more plates are stacked. The inner cover (113b) may refer to the lowest of these plates. The inner cover (113b) may cover the upper part of the receiving space (S). Additionally, the outer cover (113a) may refer to the uppermost plate among the upper covers (113). The outer cover (113a) may face the lower plate (23) of the kitchen cabinet (2).

[0200] Additionally, the housing (110) may further include a rear side facing the wall of the building. With this configuration, components of the robot vacuum cleaner station (100) can be accommodated inside the housing (110).

[0201] Additionally, a robot vacuum cleaner (200) can be accommodated inside the housing (110). The robot vacuum cleaner (200) can enter and exit the housing (110).

[0202] At this time, in this embodiment, the robot vacuum cleaner (200) can enter and exit the front of the robot vacuum cleaner station (100). Here, "front" may refer to the direction in which the door (131) is provided relative to the interior of the robot vacuum cleaner station (100).

[0203] Additionally, the term "rear" may refer to the direction opposite to the front relative to the interior of the robot vacuum cleaner station (100). For example, a wall of a building (not shown) may be placed at the rear of the robot vacuum cleaner station (100). Additionally, when looking forward from inside the robot vacuum cleaner station (100), the left side may be referred to as the left direction and the right side as the right direction.

[0204] That is, the side walls (410) of the robot vacuum cleaner station (100) can be positioned on the left and right sides of the housing body (111), respectively. An entrance (127) for the robot vacuum cleaner (200) to enter and exit can be formed at the front of the housing (110). A rear side can be positioned on the side opposite the entrance (127) of the housing (110).

[0205] Accordingly, the upper side of the housing (110) is covered by the kitchen cabinet (2), and the lower side of the housing (110) can be covered by the kitchen floor. Additionally, the left and right sides of the housing (110) are covered by the frame (400) but are positioned at the bottom of the kitchen cabinet (2). At this time, the bottom of the kitchen cabinet (2), excluding the robot vacuum cleaner station (100), is finished by a baseboard (26), so that consequently only the front of the housing (110) is exposed to the outside.

[0206] Through this, the robot vacuum cleaner station (100) and the robot vacuum cleaner (200) can be minimized from being exposed to the outside.

[0207] With such a configuration, the robot vacuum cleaner station (100) of the present invention has the effect of providing an aesthetic sense to the user in terms of interior design.

[0208] Meanwhile, the housing (110) may have a space through which a water supply hose connected to a water supply pipe passes, a space through which a drainage hose through which wastewater generated after washing the mop (242) is discharged passes, and a space through which a hose through which moisture generated during the drying process of the mop (242) is discharged passes. For example, a space through which the above hoses can pass may be formed in the side wall (410) of the housing (110).

[0209]

[0210] layout

[0211]

[0212] A robot vacuum cleaner station (100) according to an embodiment of the present invention is characterized by being installed in the lower space of a kitchen cabinet (2).

[0213] To this end, the robot vacuum cleaner station (100) according to an embodiment of the present invention is characterized by being positioned along a horizontal direction in alignment with the space formed between the lower plate (23) of the kitchen cabinet (2) and the floor of the kitchen.

[0214] Specifically, in the robot vacuum cleaner station (100) according to an embodiment of the present invention, a dust collection unit (140) and / or a mop washing unit (160) may be positioned on the side of the entrance (127).

[0215] At this time, when both the dust collection unit (140) and the mop washing unit (160) are provided, the seating unit (120) may be positioned between the dust collection unit (140) and the mop washing unit (160).

[0216] For example, an entrance (127) and a door (131) may be positioned at the front of the robot vacuum cleaner station (100). Additionally, a seating area (120) to which the robot vacuum cleaner (200) is coupled may be positioned from the entrance (127) to the rear. At this time, a dust collection unit (140) may be positioned from the front of the robot vacuum cleaner station (100) to the rear by a predetermined length. Furthermore, a mop washing unit (160) may also be positioned from the front of the robot vacuum cleaner station (100) to the rear by a predetermined length.

[0217] Accordingly, when looking at the robot vacuum cleaner station (100) from the front outer side of the robot vacuum cleaner station (100), the front of the dust collection unit (140) and / or the front of the mop washing unit (160) may be positioned on the left and right sides of the entrance (127).

[0218] At this time, the dust bag drawer (144) of the dust collection unit (140) may be provided so as to be pulled out to the front of the housing (110). In addition, the detergent container (163) of the mop washing unit (160) may be provided so as to be pulled out to the front of the housing.

[0219] Meanwhile, the rear end of the dust collection housing (141) and the detergent container (163) may be positioned at a predetermined distance from the rear end of the housing (110). Additionally, a dust collection motor (145) may be positioned between the rear end of the dust collection housing (141) and the rear end of the housing (110). With this configuration, the total space occupied by the seating portion (120), the dust collection housing (141), and the dust collection motor (145) within a limited space can be minimized.

[0220] Additionally, at least a portion of a passageway through which washing water for washing the mop (242) can flow may be arranged between the rear end of the housing (110) and the rear end of the detergent container (163). With this configuration, the path through which washing water flows from the water supply pipe can be shortened. Furthermore, within a limited space, the total space occupied by the seating portion (120), the detergent container (163), and the passageway through which washing water flows can be minimized.

[0221] Meanwhile, the robot vacuum cleaner station (100) may have a mop drying section (170) positioned behind the seating section (120). At this time, the mop drying section (170) may be positioned between the rear end of the seating section (120) and the rear end of the housing (110).

[0222] Accordingly, in the robot vacuum cleaner station (100) according to an embodiment of the present invention, a dust collection unit (140) and a mop washing unit (160) are arranged on the left and right sides based on the seating unit (120), and a mop drying unit (170) can be arranged on the rear side.

[0223] That is, in the robot vacuum cleaner station (100) according to an embodiment of the present invention, a dust collection unit (140), a mop washing unit (160), and a mop drying unit (170) can all be arranged within a predetermined distance range from the outer edge of the seating unit (120).

[0224] This has the effect of minimizing flow path loss by shortening the distance between the dust bin (220) and the dust collection unit (140) of the robot vacuum cleaner (200). Additionally, by minimizing the distance between the mop (242) and the mop washing unit (160) of the robot vacuum cleaner (200) and the distance between the mop (242) and the mop drying unit (170) of the robot vacuum cleaner (200), it has the effect of limiting the range where washing water and wastewater from washing are present.

[0225] In addition, by this arrangement, the robot vacuum cleaner station (100) of the present invention can arrange all components within a limited height.

[0226] As a result, the robot vacuum cleaner station (100) according to an embodiment of the present invention may have a dust collection unit (140), a mop washing unit (160), and a mop drying unit (170) arranged on three sides surrounding the seating unit (120), excluding the front side where the robot vacuum cleaner (200) enters. With such arrangement, even in situations where the height in the vertical direction is limited, it is possible to charge the robot vacuum cleaner (200) using a minimum horizontal space, as well as collect dust from the robot vacuum cleaner (200), wash the mop (242), and dry the mop (242).

[0227]

[0228] Settling part

[0229]

[0230] As illustrated in FIGS. 10 to 11, the robot vacuum cleaner station (100) may include a seating portion (120).

[0231] The robot vacuum cleaner (200) and the robot vacuum cleaner station (100) can be physically, electrically, and / or electrically connected through the mounting portion (120).

[0232] The seating portion (120) can be placed inside the housing (110).

[0233] An entrance (127) into which a robot vacuum cleaner (200) is introduced may be formed in front of the seating portion (120). The entrance (127) may refer to a space formed on the front surface of the robot vacuum cleaner station (100).

[0234] The entrance (127) can be formed to a size that allows the robot vacuum cleaner (200) to pass through. That is, the height of the entrance (127) is formed to be greater than the height of the robot vacuum cleaner (200). At this time, the entrance (127) may refer to a space formed upward along a vertical direction from the front end of the base (121) to be described later. Alternatively, the entrance (127) may refer to a hole formed in the door frame (132) to be described later through which the robot vacuum cleaner (200) passes.

[0235] At least one of a dust collection unit (140) and a mop washing unit (160) may be arranged on the left and right sides of the entrance (127). Accordingly, the left and right ends of the entrance (127) may be bordered by the dust collection unit (140) and the mop washing unit (160).

[0236] At this time, the entrance (127) can be opened and closed by the door (131).

[0237]

[0238] The seating portion (120) may include a receiving space (S), a base (121), a connecting wall (123), and an inner wall (124).

[0239] A robot vacuum cleaner (200) can be accommodated in the receiving space (S) of the seating portion (120). For example, the receiving space (S) may refer to a space enclosed by a base (121), a connecting wall (123), and an inner wall (124). For another example, the receiving space (S) may refer to a space enclosed by a base (121), a cleaning plate (122), a connecting wall (123), and an inner wall (124). For yet another example, the receiving space (S) may refer to a space where the robot vacuum cleaner (200) is located while connected to a power supply terminal (123b), or a space where the robot vacuum cleaner (200) is located while the dust bin (220) of the robot vacuum cleaner (200) is connected to a dust passage hole (123a).

[0240] The base (121) is configured to support the robot vacuum cleaner (200) when the robot vacuum cleaner (200) is coupled to the robot vacuum cleaner station (100). The wheel (260) of the robot vacuum cleaner (200) may come into contact with the upper surface of the base (121). Additionally, the auxiliary wheel (270) of the robot vacuum cleaner (200) may come into contact with the upper surface of the base (121).

[0241] The base (121) may include a base body (121a), an inclined portion (121b), a wheel coupling portion (121c), an agitator receiving portion (121d), and a washing tank (128).

[0242] The base body (121a) can form the overall shape of the base (121). An inclined section (121b), a wheel coupling section (121c), an agitator receiving section (121d), and a washing tank (128) may be arranged on the base body (121a).

[0243] The base body (121a) can be formed in a shape where the horizontal length and width are greater than the vertical height. Due to this structure, the robot vacuum cleaner station (100) can be stably supported on the floor surface.

[0244] A recirculation channel may be provided inside the base body (121a). Accordingly, air discharged from the dust collection motor (145) may flow through the recirculation channel (125a) formed inside the base body (121a) and be exhausted to the air recirculation port (125b).

[0245] The inclined section (121b) can be placed at the entrance where the robot vacuum cleaner (200) climbs from the base body (121a).

[0246] The inclined section (121b) may have an upward slope toward the front of the direction in which the robot vacuum cleaner (200) enters. More specifically, the inclined section (121b) may have an upward slope toward the rear, with the front end connected so as not to have a height difference from the ground. That is, the inclined section (121b) may be formed to gradually rise from the ground when the robot vacuum cleaner (200) enters. This allows the robot vacuum cleaner (200) to easily climb from the ground to the robot vacuum cleaner station (100).

[0247] The wheel (260) of the robot vacuum cleaner (200), which has moved upward along the wheel guide (121ba), can be placed on the wheel coupling portion (121c). When the wheel (260) of the robot vacuum cleaner (200) is placed on the wheel coupling portion (121c), a physical connection between the robot vacuum cleaner (200) and the robot vacuum cleaner station (100) can be achieved. To allow the robot vacuum cleaner (200) to stop stably, the surface of the wheel coupling portion (121c) can be formed to correspond to the surface of the wheel (260). The wheel coupling portion (121c) can be extended from the upper end of the wheel guide (121ba). The wheel coupling portion (121c) can be connected to the wheel guide (121ba) without a step. Thus, the robot vacuum cleaner (200) can easily move past the inclined portion (121b) to the wheel coupling portion (121c).

[0248] The wheel coupling portion (121c) may be positioned at the stopping position of the left and right wheels (260) of the robot vacuum cleaner (200) so that the robot vacuum cleaner (200) stops at the correct position. Here, the stopping position of the wheel (260) means a position determined for the robot vacuum cleaner (200) to stop in order to be connected to the power supply terminal (123b) and / or a position determined for the dust bin (220) of the robot vacuum cleaner (200) to stop in order to be connected to the dust passage hole (123a).

[0249] The shape of the wheel coupling part (121c) can be formed in an arch shape, that is, a shape corresponding to the shape of the wheel (260) of the robot vacuum cleaner (200). Through this configuration, the robot vacuum cleaner (200) can move along the wheel guide part (121ba) and stop as soon as the wheel (260) is inserted into the wheel coupling part (121c), and the wheel (260) can be stably seated on the arch-shaped wheel coupling part (121c).

[0250] At least a portion of the agitator (250) of the robot vacuum cleaner (200) can be accommodated in the agitator receiving portion (121d).

[0251] The agitator receiving portion (121d) may be formed between the wheel coupling portions (121c). The agitator receiving portion (121d) may be formed in a shape corresponding to the agitator (250) of the robot vacuum cleaner (200). The agitator receiving portion (121d) may be formed in a rectangular shape with an open top. The lower surface of the agitator receiving portion (121d) may be sealed by the bottom surface of the base body (121a) or the bottom surface of the housing (110). Accordingly, the agitator (250) of the robot vacuum cleaner (200), which has moved upward along the inclined portion (121b), may be seated in the agitator receiving portion (121d). At this time, the depth of the agitator receiving portion (121d) may be formed shallower than the depth of the wheel coupling portion (121c).

[0252] The agitator receiving portion (121d) can be formed to be recessed from the base body (121a). In this way, when the wheel (260) of the robot vacuum cleaner (200) is seated on the wheel coupling portion (121c), the agitator receiving portion (121d) can provide a space for the lower part of the agitator (250) to be received.

[0253] An air return port (125b) may be formed in the agitator receiving section (121d). The air return port (125b) may be formed on the side of the agitator receiving section (121d). The air return port (125b) may connect the agitator receiving section (121d) and the dust collection motor (145) through a return path. The agitator receiving section (121d) and the return path may be in communication through the air return port (125b). Thus, air discharged from the dust collection motor (145) may pass through the air return port (125b) and be discharged into the agitator receiving section (121d).

[0254] The agitator receiving portion (121d) can guide air discharged through the air circulation port (125b) to the suction portion (211) of the robot vacuum cleaner (200).

[0255] Meanwhile, the base (121) may be provided to be withdrawable from the housing (110) and the drawer (190). At this time, the base (121) may be withdrawn through the entrance (127) along the space between the inner walls (124).

[0256] To facilitate this, a base handle (121e) may be formed on the base (121). The base handle (121e) may be formed between the agitator receiving portion (121d) and the auxiliary wheel guide portion (121bb). Additionally, the base handle (121e) may be formed between a pair of wheel guide portions (121ba).

[0257] The base handle (121e) may be formed in a recessed shape on the base body (121a), and may be formed in a recessed shape extending from the rear to the front and downward. For example, the base handle (121e) may be formed in an elliptical groove shape, with a cover formed at the front and an open shape at the rear.

[0258] With this configuration, the user can easily pull out the base (121) by grasping and pulling the handle (121e).

[0259] The connecting wall (123) is configured to accommodate the dust passage hole (123a), power supply terminal (123b), and water supply nozzle (123c) of the robot vacuum cleaner station (100). The connecting wall (123) can spatially separate the receiving space (S) from the parts of the robot vacuum cleaner station (100). The connecting wall (123) can extend along the vertical direction from the rear side of the base (121). The connecting wall (123) can be formed in correspondence with the shape of the robot vacuum cleaner (200). For example, if the body (210) of the robot vacuum cleaner (200) is cylindrical, the connecting wall (123) can be formed in an arc shape having a predetermined radius. With such a configuration, the outer perimeter of the robot vacuum cleaner (200) can be surrounded, and the surface area facing the outer surface of the robot vacuum cleaner (200) can be increased. Additionally, the robot vacuum cleaner (200) can be stably supported.

[0260] A dust passage hole (123a) may be formed in the seating portion (120) to allow air from outside the housing (110) to flow into the interior. Specifically, a dust passage hole (123a) may be formed in the coupling wall (123) to allow air from outside the housing (110) to flow into the interior. At this time, the dust passage hole (123a) may be positioned at the rear of the dust collection housing (141) to be described later.

[0261] The dust passage hole (123a) may be connected to the dust bin (220) of the robot vacuum cleaner (200). The dust passage hole (123a) may be connected to the dust outlet (221) of the dust bin (220) of the robot vacuum cleaner (200). The dust passage hole (123a) may be formed in the shape of a hole corresponding to the shape of the dust bin (220) so that dust from the dust bin (220) flows into the dust collection unit (140).

[0262] The dust passage hole (123a) can be formed to communicate with the dust collection passage (147, 148). Air sucked into the dust passage hole (123a) can be exhausted through the air return section (125) after flowing through the dust collection passage (147, 148).

[0263] The robot vacuum cleaner station (100) may include a power supply module that supplies power to the robot vacuum cleaner (200). The power supply module includes a power supply module housing and a power supply terminal (123b), and a circuit board and components for power supply may be mounted within the power supply module housing. The power supply terminal (123b) may be positioned forward from the power supply module housing and exposed on the coupling wall (123).

[0264] The power supply terminal (123b) can supply power to a robot vacuum cleaner (200) coupled to the mounting portion (120). The power supply terminal (123b) can be electrically connected by contacting the charging terminal of the robot vacuum cleaner (200). The power supply terminal (123b) can be placed on the mounting portion (120). Specifically, the power supply terminal (123b) can be placed on the coupling wall (123). The power supply terminal (123b) can be electrically connected to the robot vacuum cleaner (200) coupled to the coupling wall (123). The power supply terminal (123b) can supply power to the battery of the robot vacuum cleaner (200) coupled to the coupling wall (123).

[0265] The robot vacuum cleaner station (100) may further include a water supply nozzle (123c).

[0266] The water supply nozzle (123c) can be connected to the supply section (231) of the water tank (230) of the robot vacuum cleaner (200). Specifically, the water supply nozzle (123c) can be connected to the inlet of the water tank (230). The water supply nozzle (123c) can supply water supplied from the water supply pipe of the kitchen cabinet (2) to the storage space inside the water tank (230) of the robot vacuum cleaner (200).

[0267] Additionally, the robot vacuum cleaner station (100) may further include a coupling guide (123d). The coupling guide (123d) can be coupled with a coupling groove formed in the robot vacuum cleaner (200) while the robot vacuum cleaner (200) is seated on the seating portion (120). Through this, the coupling guide (123d) can guide the robot vacuum cleaner (200) to be accurately coupled in the correct position. The coupling guide (123d) can be positioned between a pair of external air discharge portions (171c).

[0268] Additionally, the coupling guide (123d) may include a sensor that detects the coupling state. Through this, it is possible to detect whether the robot vacuum cleaner (200) is properly seated.

[0269] The inner wall (124) is configured to spatially separate the receiving space (S) of the seating portion (120) from the parts of the robot vacuum cleaner station (100). A pair of inner walls (124) may be arranged on the left and right sides of the base (121). The inner walls (124) may be connected to both ends of the connecting wall (123). The inner walls (124) may extend from the left and right sides of the base (121) in a direction intersecting the base (121). Specifically, the inner walls (124) may extend vertically from the left and right sides of the base (121).

[0270] Meanwhile, various components such as dust collection channels (147, 148), dust collection unit (140), dust collection motor (145), detergent container (163), and wastewater container (166) may be arranged on the outer side of the inner wall (124). Specifically, the dust collection unit (140), detergent container (163), and wastewater container (166) may be arranged in the space between the inner wall (124) and the side wall (410) of the housing (110).

[0271] The dust collector (140) and the detergent container (163) can be separated by sliding from the space between the inner wall (124) and the side wall (410) of the housing (110). The left-right width of the dust collector (140) and the detergent container (163) can be formed to be smaller than the distance between the inner wall (124) and the side wall (410) of the housing (110).

[0272] The cleaning plate (122) is configured to clean the mop of the robot vacuum cleaner (200), and the cleaning plate (122) can be placed in the cleaning tank (128) of the base (121). Additionally, the cleaning plate (122) can come into contact with the mop (242) while the robot vacuum cleaner (200) is placed thereon.

[0273] The cleaning plate (122) may be a plate formed to slope downward as it faces the center overall.

[0274] Specifically, the cleaning plate (122) includes a flow guide surface (122c) formed in a curved shape. In addition, at least one passage hole (122b) through which fluid can pass may be formed in the flow guide surface (122c). Furthermore, a cleaning projection (122a) may be formed protrudingly on the flow guide surface (122c).

[0275] At this time, a pair of cleaning protrusions (122a) may be symmetrically formed on the fluid guide surface (122c). Specifically, a pair of cleaning protrusions (122a) may be positioned vertically below a pair of mops (242) of a robot vacuum cleaner (200), positioned to face the pair of mops (242), and positioned to be able to contact at least a part of the pair of mops (242).

[0276] Additionally, multiple through holes (122b) may be formed on the flow guide surface (122c), and may be formed between a pair of washing protrusions (122a). For example, multiple through holes (122b) may be formed on the flow guide surface (122c), including the lowest position from the ground (kitchen floor), and may be formed between a pair of washing protrusions (122a). Through this, fluid discharged between a pair of washing protrusions (122a) can be guided into the through holes (122b) and flow.

[0277] Meanwhile, the height of the flow guide surface (122c) from the kitchen floor can increase as it moves further back from the location where the through hole (122b) is formed. That is, the height of the flow guide surface (122c) from the kitchen floor can increase as it approaches the external air discharge section (171c) to be described later.

[0278] With this configuration, washing water and / or air can flow along the flow guide surface (122c) and escape through the through hole (122b) into the space formed between the washing plate (122) and the washing tank (128).

[0279] When washing water is supplied to the washing plate (122) and the mop (242) is rotated, the mop (242) can be washed by friction with the stationary washing protrusion (122a).

[0280] Meanwhile, at least a portion of the cleaning plate (122) may be positioned above the flow path forming portion (128c) to be described later. That is, the cleaning plate (122) may further include a reflux flow path cover portion (122d) that is formed to protrude upward from the flow guide surface (122c) and is coupled to the upper side of the flow path forming portion (128c).

[0281] The cleaning plate (122) of the present embodiment may be formed in a shape corresponding to the shape of the flow path forming portion (128c). For example, the front left portion of the cleaning plate (122) may be formed to protrude upward from the flow guide surface (122c) to cover the lower flow path forming portion (128c).

[0282] With this configuration, the washing plate (122) and the washing tank (128) can be accurately combined, while also providing sufficient space to form a reflux channel (125a).

[0283] The washing tank (128) is configured to accommodate the washing plate (122). The washing tank (128) may be positioned at the rear side of the base body (121a). The washing tank (128) is positioned at the lower side of the washing plate (122) and is detachably coupled to the washing plate (122). The washing tank (128) may be formed to correspond to the washing plate (122) so that the washing plate (122) can be fitted into it. Liquid that has passed through the washing plate (122) may flow into the washing tank (128).

[0284] The washing tank (128) may include a washing tank base surface (128a) through which fluid passing through the washing plate (122) flows, and a washing tank wall (128b) that is formed to protrude vertically from the outer edge of the washing tank base surface (128a). At this time, the height of the washing tank base surface (128a) from the ground (kitchen floor) may decrease as it moves toward the rear of the robot vacuum cleaner station (100). Through this, fluid passing through the washing plate (122) can be collected at the rear of the washing tank (128) and discharged to the outside through the wastewater inlet (164c) to be described later.

[0285] At this time, a sewage pipe connection port (128d) may be formed in the wall of the washing tank (126b) for connection with the sewage inlet port (164c).

[0286] Meanwhile, a flow path forming portion (128c) may be formed in the washing tank (128). The flow path forming portion (128c) may be formed protruding upward from the base surface (128a) of the washing tank to form a reflux flow path (125a) on the lower side. Specifically, at least a portion of the reflux flow path (125a) may be formed between the lower surface of the base (121) and the flow path forming portion (128c).

[0287] Meanwhile, in the present invention, the washing tank (128) is provided to be withdrawable from the mop washing unit (160). That is, the washing tank (128) can be withdrawn from the housing (110) together with the base (121). Along with this, the washing plate (122) can also be withdrawn from the mop washing unit (160).

[0288]

[0289] Door section

[0290]

[0291] The door portion (130) may be provided to cover the entire front end of the housing (110). The door (131) may cover the dust bag drawer (144) and the detergent container (163) so that they are not exposed to the outside.

[0292] The door (131) can form the front exterior of the robot vacuum cleaner station (100) when the entrance (127) is closed. For example, the door (131) can be formed in a shape similar to a rectangular flat plate. The left-right length of the door (131) can be provided to be greater than or equal to the left-right length of the housing (110). With this configuration, the dust bag drawer (144) and the detergent container (163) can be protected from the outside, and the appearance of the robot vacuum cleaner station (100) can be made neat.

[0293] A door frame (132) may be positioned at the front of the housing (110). A door (131) is connected to the door frame (132) so that it can be opened and closed. Additionally, the door frame (132) may be formed with an entrance (127) through which a robot vacuum cleaner (200) can enter and exit, a dust bag outlet (132a) to which a dust bag drawer (144) can be pulled out, and a detergent container insertion opening (132b) to which a detergent container (163) can be pulled out.

[0294] The door frame (132) can form the front exterior of the robot vacuum cleaner station (100) when the door (131) is open.

[0295] When the door (131) opens the entrance (127), at least one side of the dust bag drawer (144) and at least one side of the detergent container (163), which are connected to the door frame (132), may be provided to be exposed to the outside. When the door (131) opens the entrance (127), the front side of the dust bag drawer (144) and the front side of the detergent container (163) are exposed to the outside, and the handle (144d) of the dust bag drawer (144) and the handle (163b) of the detergent container (163) are exposed to the outside. With this configuration, the dust bag drawer (144) and the detergent container (163) can be easily pulled out or inserted and can provide a neat appearance.

[0296] The door (131) has a rotation axis (131a) positioned at the bottom of the door frame (132) and can be positioned parallel to the floor surface when opening the doorway (127) or formed to slope downward toward the front so that the end contacts the ground.

[0297] The door (131) is provided with a hinge portion so that it can be rotatably connected to the door frame (132). Multiple hinge portions may be spaced apart along the rotation axis (131a) and spaced apart at different intervals.

[0298] Additionally, the door (131) may be provided with an auxiliary entryway (131b) on the side facing the housing (110) when the entrance (127) is closed. The auxiliary entryway (131b) is provided so that the robot vacuum cleaner (200) can travel stably to the landing area (120) or the entrance (127), and may be provided with an upward slope toward the rear.

[0299] Specifically, the auxiliary entryway (131b) can be formed in the shape of a groove to ensure stable inclined driving of the robot vacuum cleaner (200). The auxiliary entryway (131b) may have grooves formed along the left and right directions spaced apart at equal intervals in the front and rear directions. The width of the auxiliary entryway (131b) in the left and right directions may become narrower as it moves toward the rear. Accordingly, as the wheels (260) of the robot vacuum cleaner (200) move toward the seating portion (120) or the entrance (127), left and right movement is restricted and the wheels can be guided to the correct position.

[0300] The auxiliary entryway (131b) guides the wheel (260) to the wheel guide section (121ba) positioned on the seating section (120). The auxiliary entryway (131b) is provided in a pair and can be positioned at each location continuous with the pair of wheel guide sections (121ba).

[0301] Meanwhile, the door (131) may be driven according to whether the robot vacuum cleaner (200) approaches, whether it starts driving, etc., or according to the input of the door control unit (133).

[0302] The door frame (132) is equipped with an entry sensor (135) to detect the approach of the robot vacuum cleaner (200). The entry sensor (135) may be positioned at the front of the housing (110) to detect the approach of the robot vacuum cleaner (200). For example, the entry sensor (135) may be an IR sensor.

[0303] The entry sensor (135) can be installed on the upper side of the front surface of the door frame (132). This allows the detection range to be maximized. Additionally, the entry sensor (135) can be installed in the center of the left and right directions of the entrance (127). This allows the entry direction of the robot vacuum cleaner (200) to be guided through communication with the robot vacuum cleaner (200).

[0304] Meanwhile, in order for the entry sensor (135) to detect the front even when the door (131) is closed to the entrance (127), the door (131) may be formed in a shape with a cut-out position facing the entry sensor (135). Alternatively, the door (131) may be provided with a transparent window at a position facing the entry sensor (135).

[0305] A door operating part (133) is installed on the door frame (132) so that the door (131) can be rotated by the user's operation.

[0306] The door control unit (133) is positioned on the door frame (132) and may be provided with at least one button for operating the door (131). The door control unit (133) can rotate the door (131) regardless of the position or state of the robot vacuum cleaner (200). The door control unit (133) may be provided with a single button for opening or closing the door (131), or may be provided with a button for opening the door (131) and a button for closing the door (131), respectively.

[0307] The door control unit (133) may be positioned inside the door frame (132). Additionally, the door control unit (133) may be positioned so that at least one button is exposed to the outside.

[0308] At this time, the button may be positioned adjacent to the detergent container (163) relative to the entrance. For example, the button may be positioned above the handle (163b) of the detergent container (163).

[0309] Meanwhile, when the door (131) closes the entrance (127), it also covers the door control unit (133). At this time, the door (131) is provided with an external button unit (131c) so that the door control unit (133) can be operated even when the entrance (127) is closed. The external button unit (131c) is composed of the same number of buttons as the door control unit (133) and is provided in a position facing the buttons. The external button unit (131c) is formed of an elastically deformable material so that it can press the buttons when an external force is applied.

[0310] The door (131) can be rotated by a door drive unit (134). For example, the door drive unit (134) may include a door drive motor and a drive gear unit.

[0311] The door drive motor can be placed inside the housing (110) and in the upper space of the detergent container (163). The door drive motor can be placed between the detergent container (163) and the upper cover (113) of the housing (110). Additionally, the door drive motor can be placed forward in the space provided between the side wall (410) and the seating portion (120). That is, the door drive motor can be placed adjacent to the door operating portion (133).

[0312] Through this, space utilization is improved and accessibility is enhanced, providing convenience to users.

[0313] The drive gear unit is configured to transmit power by connecting the door drive motor and the door (131). The drive gear unit transmits the driving force of the door drive motor to the door (131) to rotate the door (131).

[0314]

[0315] Dust collector

[0316]

[0317] The dust collection unit (140) can collect dust from the dust bin (220) of the robot vacuum cleaner (200). The dust collection unit (140) can be placed inside the housing (110). The dust collection unit (140) can be placed outside the seating unit (120). That is, the dust collection unit (140) can be placed between the housing (110) and the seating unit (120). For example, the dust collection unit (140) can be placed on one side in the left-right direction of the seating unit (120).

[0318] The dust collection unit (140) may include a dust collection unit housing (141), a filter (142), a dust bag (143), a dust bag drawer (144), a dust collection motor (145), a dust collection motor housing (146), a first dust collection path (147), and a second dust collection path (148).

[0319] The dust collection housing (141) can form a space inside which a filter (142), a dust bag (143), and a dust bag drawer (144) can be accommodated.

[0320] The dust collection housing (141) is coupled to the inside so that a dust bag drawer (144) can be pulled out, and a dust bag (143) can be stored inside the dust bag drawer (144). For example, the dust collection housing (141) is formed in the shape of a rectangular tube with an open front, and the rear internal space can be connected to the first dust collection path (147) and the second dust collection path (148).

[0321] The dust collection housing (141) can receive dust from inside the dust bin (220).

[0322] One side of the interior of the dust collection housing (141) may be in communication with the first dust collection path (147), and the other side may be in communication with the second dust collection path (148). Additionally, when a dust bag (143) is attached to the dust collection housing (141), the dust bag (143) may be in communication with the first dust collection path (147) inside the dust collection housing (141).

[0323] The filter (142) may be provided in the dust bag drawer (144). Specifically, the filter (142) may be placed inside the dust bag drawer and pulled out together with the dust bag drawer (144).

[0324] Meanwhile, the filter (142) may be positioned lower than the inlet (141b) relative to the bottom surface of the dust bag drawer body (141a). The filter (142) may be positioned forward of the outlet (144c) of the dust bag drawer (144).

[0325] Specifically, the filter (142) can be detachably coupled to the lower surface of the dust bag drawer (144). At this time, the filter (142) can be positioned at one end (front) in the longitudinal direction of the flow path forming part (144e). Thus, the filter (142) can be positioned between the handle (144d) and the flow path forming part (144e). That is, the filter (142) can be positioned adjacent to the front of the dust bag drawer (144).

[0326] The filter (142) can be pulled out together with the dust bag drawer (144) when the dust bag drawer (144) is pulled out. That is, when the handle (144d) is pulled, the filter (142) can be pulled out together with the dust bag drawer (144). At this time, since the filter (142) is positioned immediately behind the handle (144d), there is an advantage that the user can easily replace the filter (142) even when only a part of the dust bag drawer (144) has been pulled out.

[0327] Meanwhile, the filter (142) may be spaced apart from both sides in the left-right direction (width direction) of the dust bag drawer (144). That is, a space may be formed between the filter (142) and both sides in the left-right direction of the dust bag drawer body (144a). At this time, a user's finger may enter the space.

[0328] With this configuration, the user can remove the filter (142) by a simple motion of inserting a finger into the space between the filter (142) and the dust bag drawer body (144a) and pulling the filter (142).

[0329] The filter (142) may be positioned below the dust bag (143). At this time, the dust bag (143) may be detachably connected to the dust bag drawer (144) in a sliding manner along the vertical direction.

[0330] Accordingly, the dust bag (143) can be separated along the vertical direction from the dust bag drawer (144) when the dust bag drawer (144) is withdrawn, and the filter (142) can be exposed to the outside when the dust bag (143) is separated.

[0331] Therefore, whenever the user replaces the dust bag (143), the condition of the filter (142) can be checked, and the filter (142) can also be easily replaced along with the replacement of the dust bag (143).

[0332] The dust bag (143) may refer to a dust bag that collects dust sucked in from inside the dust bin (220) of the robot vacuum cleaner (200) by the dust collection motor (145).

[0333] The dust bag (143) can be detachably coupled to the dust bag drawer (144). Thus, the dust bag (143) can be separated from the dust bag drawer (144) and discarded, and a new dust bag (143) can be coupled to the dust bag drawer (144). That is, the dust bag (143) can be defined as a consumable part.

[0334] The inlet of the dust bag (143) can be arranged to communicate with the inlet (144b) of the dust bag drawer (144). Thus, when the dust collection motor (145) is operated, air and dust inside the dust container (220) can be drawn into the dust bag (143) and collected.

[0335] The dust bag (143) can be provided so that when suction force is generated by the dust collection motor (145), its volume increases and dust is contained inside. To this end, the dust bag (143) can be made of a material that allows air to pass through but does not allow foreign substances such as dust to pass through. For example, the dust bag (143) can be made of a non-woven fabric material and can have a cuboid shape corresponding to the shape of the dust bag drawer (144) when its volume increases.

[0336] The dust collection unit (140) may further include a dust collection module. The dust collection module may provide an intake airflow to the dust collection path.

[0337] Specifically, the dust collection unit (140) may further include a dust collection motor (145) and a dust collection motor housing (146).

[0338] The dust collection motor (145) can generate suction force in the dust collection path (147, 148). That is, the dust collection motor (145) can provide suction force to suck dust from the dust container (220) into the dust bag (143) placed in the dust collection housing (141).

[0339] The dust collection motor (145) can be positioned at the rear of the dust collection housing (141). By doing so, the dust collection motor (145) can provide suction power to suck up dust inside the dust bin (220) of the robot vacuum cleaner (200).

[0340] The dust collection motor (145) can generate suction force by rotation. For example, although not illustrated, the dust collection motor (145) may include a rotor and a stator that rotate relative to each other when power is applied, and may include an impeller that rotates around a rotation axis according to the rotation of the rotor. Thus, suction force can be generated by the rotation of the impeller.

[0341] One side of the dust collection motor (145) may be connected to the second dust collection path (148), and the other side may be connected to the recirculation path (125a). When the dust collection motor (145) is driven, air flowing through the second dust collection path (148) may be introduced into the interior of the dust collection motor housing (146). Additionally, the air introduced into the interior of the dust collection motor housing (146) may flow through the recirculation path (125a) after passing through the dust collection motor (145).

[0342] Meanwhile, in this embodiment, the rotation axis of the dust collection motor (145) may be arranged along the vertical direction. In this case, the horizontal space occupied by the dust collection motor (145) can be minimized.

[0343] Meanwhile, if the rotation axis of the dust collection motor (145) is arranged along the vertical direction, the height of the side where air flows into the dust collection motor (145) and the side where air is discharged from the dust collection motor (145) can be arranged differently. Accordingly, the structure of the dust collection motor housing (146) can be formed.

[0344] The dust collection motor housing (146) can accommodate a dust collection motor (145) inside. The dust collection motor housing (146) can be positioned at the rear of the dust collection unit housing (141). Additionally, the dust collection motor housing (146) can be positioned at the rear of the first dust collection path (147). Additionally, the dust collection motor housing (146) can be positioned at the rear of the second dust collection path (148).

[0345] That is, based on the front-rear direction of the robot vacuum cleaner station (100), the dust collection housing (141) may be positioned furthest forward, and the first dust collection path (147) and the second dust collection path (148) may be positioned behind the dust collection housing (141). Additionally, the dust passage hole (123a) may be positioned behind the first dust collection path (147), and the dust collection motor housing (146) may be positioned behind the second dust collection path (148). Additionally, the dust collection motor housing (146) may be positioned behind the dust passage hole (123a).

[0346] Accordingly, the dust collection unit (140) is positioned along the front and rear directions of the robot vacuum cleaner station (100) to have the effect of lowering the overall height.

[0347] Meanwhile, the dust collection unit (140) may further include dust collection channels (147, 148). A dust collection channel may refer to a channel through which air sucked in through a dust passage hole (123a) flows through a dust bag to a dust collection motor (145).

[0348] Specifically, the dust collection path may include a first dust collection path (147) that connects the dust bin (220) and the internal space of the dust collection unit housing (141) when the robot vacuum cleaner (200) is connected to the robot vacuum cleaner station (100) and the dust passage hole (123a) and the dust bin (220) of the robot vacuum cleaner (200) are connected, and a second dust collection path (148) that connects the internal space of the dust collection unit housing (141) and the internal space of the dust collection motor housing (146).

[0349] The first dust collection channel (147) can connect the dust bin (220) of the robot vacuum cleaner (200) and the internal space of the dust collection housing (141). The first dust collection channel (147) can connect the dust passage hole (123a) of the seating portion (120) and the internal space of the dust collection housing (141). The first dust collection channel (147) can be formed along a direction intersecting the vertical direction. For example, the first dust collection channel (147) can be formed close to the horizontal direction. The first dust collection channel (147) can be a space formed towards the rear from the dust passage hole (123a), or a channel formed by bending toward the side from the dust passage hole (123a) to allow dust and air to flow. Dust inside the dust bin (220) of the robot vacuum cleaner (200) can move into the internal space of the dust collection housing (141) through the first dust collection channel (147).

[0350] The second dust collection channel (148) can connect the internal space of the dust collection unit housing (141) and the internal space of the dust collection motor housing (146). The second dust collection channel (148) can be formed along a direction intersecting the vertical direction. For example, the second dust collection channel (148) can be formed close to the horizontal direction.

[0351] In this case, in the present invention, the first dust collection channel (147) and the second dust collection channel (148) may be formed at different heights. That is, the first dust collection channel (147) and the second dust collection channel (148) may be arranged in a stacked structure. At least a portion of the first dust collection channel (147) may be positioned above the second dust collection channel (148).

[0352] With this configuration, multiple Euros can be arranged close to the horizontal direction to lower the overall height, and at the same time, by stacking them, the width in the left and right directions and the overall volume of the robot vacuum cleaner station (100) can be minimized.

[0353]

[0354] Mop washing section

[0355]

[0356] Meanwhile, the mop washing unit (160) of the robot vacuum cleaner station (100) according to an embodiment of the present invention is described as follows.

[0357] A robot vacuum cleaner station (100) according to an embodiment of the present invention may include a mop washing unit (160). The mop washing unit (160) supplies washing water to the mop (242) of the robot vacuum cleaner (200) coupled to the mounting unit (120) to wash the mop (242), and can drain the wastewater after washing the mop (242).

[0358] The mop washing unit (160) may include a washing water supply unit that mixes a liquid containing detergent with purified water and discharges it to the upper side of the washing plate (122). The washing water supply unit may include a regulator (161), a mixing chamber (162), a detergent container (163), a branching path (164), and a washing water nozzle (165).

[0359] At this time, the detergent container (163) and the wastewater container (166) can be accommodated in the space formed between the inner wall (124) and the side wall (410) of the housing. The detergent container (163) can be placed on the lower side of the space between the inner wall (124) and the side wall (410) of the housing, and the wastewater container (166) can be placed on the upper side of the detergent container (163).

[0360] The water supply pipe of the kitchen cabinet (2) is connected to a regulator (161) so that the flow rate supplied from the water supply pipe can be regulated. Additionally, some of the purified water that has passed through the regulator (161) can be supplied to the water tank (230) of the robot vacuum cleaner (200) through the water supply nozzle (123c), and the remainder can be supplied to the mixing chamber (162).

[0361] Additionally, the liquid containing the detergent stored in the detergent container (163) can be supplied to the mixing chamber (162) through the flow force of the pump. The detailed structure of the detergent container (163) will be described later.

[0362] The mixing chamber (162) is provided with a space in which a liquid containing detergent and purified water can be introduced and mixed, and can discharge washing water mixed with detergent and purified water. This mixing chamber (162) may be provided with a purified water inlet (162a), a detergent inlet (162b), and a branch flow path connector (162c).

[0363] The mixing chamber (162) is provided inside the housing (110) and may be positioned further back than the seating portion (120). At this time, a flow path (161a) through which purified water flows in from the regulator (161) may be connected to the purified water inlet (162a). Additionally, a flow path (163a) through which liquid containing detergent flows in from the detergent container (163) may be connected to the detergent inlet (162b). Accordingly, the pumps of the regulator (161) and the detergent container (163) can operate for a certain period of time to flow a preset amount of purified water and detergent into the mixing chamber (162).

[0364] Meanwhile, the branch flow path connector (162c) can be connected to the branch flow path (164). The branch flow path (164) can supply washing water mixed with purified water and detergent to each of the pair of washing water nozzles (165).

[0365] The branched flow path (164) may be formed in a shape where one pipe is branched into two, and at this time, one end of the branched path may be connected to one of a pair of washing water nozzles (165), and the other end of the branched path may be connected to the other of a pair of washing water nozzles (165).

[0366] A pair of wash water nozzles (165) may be spaced apart. At this time, the pair of wash water nozzles (165) may be positioned symmetrically to each other.

[0367] Additionally, the washing water nozzle (165) is connected to a branching channel (164) to allow washing water to flow into it and discharge washing water onto the washing plate (122). The washing water nozzle (165) can discharge washing water onto the upper surface of the washing plate (122) through the washing water discharge port (165a). The washing water discharge port (165a) can be opened in a direction facing the upper surface of the rag (242) placed on the washing plate (122). More specifically, the washing water discharge port (165a) formed in the washing water nozzle (165) can discharge washing water toward the washing protrusion (122a) of the washing plate (122).

[0368] A washing water nozzle (165) may be provided on a nozzle installation wall connected to a connecting wall (123). The washing water nozzle (165) may be positioned higher than the top of the washing plate (122) so that the washing plate (122) can be detached. Accordingly, when the washing plate (122) is detached or the drawer (190) is pulled out, the washing plate (122) and the washing tank (128) do not collide with the washing water nozzle (165), and a washing water discharge space can be provided between the nozzle installation wall and the washing plate (122).

[0369] Additionally, the washing water nozzle (165) may be positioned vertically upward from a location spaced apart from the center in the width direction of the washing protrusion (122a). Specifically, when the rotation direction of the mop (242) during the washing process of the mop (242) is considered as one direction, the washing water nozzle (165) may be positioned in the other direction from the center in the width direction of the washing protrusion (122a). With this configuration, washing water can flow along the center in the width direction of the washing protrusion (122a).

[0370] The detergent container (163) includes a detergent container body (163a), a handle (163b), and a detergent container rail (163c).

[0371] The detergent container body (163a) can provide a space for storing a liquid containing detergent. For example, the detergent container body (163a) can be formed in the shape of a box with an open top.

[0372] A handle (163b) may be provided on the front of the detergent container body (163a). The handle (163b) may be provided so that a user can grip it. For example, the handle (163b) may be formed by being recessed from the front surface of the detergent container body (163a) toward the rear.

[0373] With this configuration, when a user grasps the handle (163b) and pulls it forward, the detergent container body (163a) can be pulled forward and withdrawn together. Therefore, according to the present invention, the user can easily pull the detergent container (163) forward and then supply detergent.

[0374] A detergent container rail (163c) may be formed on the detergent container body (163a). The detergent container rail (163c) can guide the movement of the detergent container body (163a).

[0375] For example, the detergent container rail (163c) may be formed in the shape of a groove or rib along the front-rear direction on the left-right side of the detergent container body (163a).

[0376] With this configuration, when a user attaches the detergent container (163) to the housing (110), it can be attached in the correct position and prevent the washing water from leaking out.

[0377] Meanwhile, although not shown, a rail may be formed on the housing (110) corresponding to the detergent container rail (163c). The rail may be formed corresponding to the shape and position of the detergent container rail (163c).

[0378] The wastewater tank (166) can provide a space for storing the washing water used to wash the mop (242). After the washing of the mop (242) is finished, the washing water discharged onto the upper surface of the washing plate (122) can be drained into the passage hole (122b) while descending along the slope of the washing plate (122). The washing water that passes through the passage hole (122b) accumulates in the washing tank (128). Additionally, the washing water accumulated in the washing tank (128) can flow into the wastewater suction path (166b) through the wastewater inlet (166a) and can flow into the wastewater tank (166) by passing through the wastewater inlet path (166b). That is, the liquid that passes through the washing plate (122) can flow along the washing tank (128) and be discharged through the wastewater inlet (166a).

[0379] Meanwhile, the sewage suction channel (166b) is formed in the sewage suction pipe, and a sewage inlet (166a) is formed at one end of the sewage suction pipe, and the other end of the sewage suction pipe is connected to the sewage tank (166). At this time, the sewage suction pipe may be positioned to pass through the lower side of the outside air supply module (171). That is, the sewage suction channel (166b) may be positioned on the lower side of the outside air supply module (171). Additionally, the sewage suction channel (166b) may be positioned on the lower side of the outside air supply channel (171a).

[0380] The washing water stored in the wastewater tank (166) can be drained through the wastewater discharge path (167) to the drain pipe (25) of the kitchen cabinet (2). One end of the wastewater discharge path (167) can be connected to the wastewater tank (166), and the other end can be connected to the drain pipe (25). At this time, the washing water stored in the wastewater tank (166) can be drained through the wastewater discharge path (167) by a centrifugal pump (not shown) to the drain pipe (25).

[0381] The wastewater discharge path (167) connected to the wastewater tank (166) can be connected upstream (25b) based on the U-trap (25a) of the drain pipe (25) of the kitchen cabinet (2). This is because if the wastewater discharge path (167) is connected downstream (25c) based on the U-trap (25a) of the drain pipe (25), odors or fluid inside the drain pipe (25) may flow back into the wastewater discharge path (167).

[0382] Additionally, the mop washing unit (160) may include a check valve (not shown). The check valve can prevent fluid inside the drain pipe (25) from flowing back into the wastewater discharge path (167). The check valve may be provided at the other end of the wastewater discharge path (167) connected to the drain pipe (25).

[0383]

[0384] Mop drying section

[0385]

[0386] FIG. 12 shows a plan view illustrating a mop drying section of a robot vacuum cleaner station according to an embodiment of the present invention. FIG. 13 shows a cross-sectional view along line AA of FIG. 12. FIG. 14 shows a cross-sectional view along line BB of FIG. 12.

[0387] Referring to FIGS. 12 to 14, a robot vacuum cleaner station (100) according to one embodiment of the present invention may include a mop drying unit (170). At this time, the mop drying unit (170) can dry the mop (242) of the robot vacuum cleaner (200) that has been washed by the mop washing unit (160) or the mop (242) that is wet after a water cleaning operation is finished.

[0388] The mop drying unit (170) may include an external air supply module (171) and an air discharge unit (172).

[0389] The outside air supply module (171) can heat air outside the housing (110) and supply it to the receiving space (S). The outside air supply module (171) may include an outside air supply path (171a), an outside air inlet (171b), an outside air discharge section (171c), a heater (171d), and a blower fan (171e).

[0390] An external air supply channel (171a) is formed in the external air supply module (171). The external air supply channel (171a) can flow external air to the external air discharge section (171c).

[0391] The outside air supply channel (171a) can connect the external space and the receiving space of the housing (110). One side of the outside air supply channel (171a) can be in communication with the external space through the outside air inlet (171b), and the other side of the outside air supply channel (171a) can be in communication with the receiving space (S) through the outside air discharge section (171c). A blower fan (171e) and a heater (171d) can be arranged in sequence on the outside air supply channel (171a). The height of the outside air supply channel (171a) can decrease from the blower fan (171e) to the heater (171d).

[0392] With this configuration, the airflow velocity passing through the outside air supply channel (171a) can be increased. Accordingly, the heating efficiency of the heater (171d) through the heater (171d) can be increased.

[0393] An external air inlet (171b) may be formed on the rear surface (111b) of the housing (110). Air from outside the housing (110) may be introduced into the external air supply path (171a) through the external air inlet (171b). Thus, air from outside the housing (110) may be introduced into the interior of the housing (110).

[0394] At least a portion of the external air discharge section (171c) may be positioned above the cleaning plate (122). The external air discharge section (171c) may be open in a direction facing the cleaning plate (122). A pair of external air discharge sections (171c) may be provided in a state where they are open downwards. A pair of external air discharge sections (171c) may be formed symmetrically on the left and right with respect to a virtual shaft axis (a1) extending the shaft rotation axis of the blower fan (171e).

[0395] The outside air discharge section (171c) can discharge air that has passed through the outside air supply path (171a). The outside air discharge section (171c) can be positioned in front of the heater (171d). The outside air discharge section (171c) can discharge air heated by the heater (171d) into the receiving space (S). The air heated by the heater (171d) can be branched to the left and right and discharged through a pair of outside air discharge ports (171ca).

[0396] Through this configuration, a pair of external air discharge units (171c) can dry a mop (242) positioned symmetrically on the lower side of the robot vacuum cleaner (200). Additionally, it can prevent heat from being concentrated in a specific area, thereby increasing the drying efficiency of the mop (242).

[0397] In particular, the external air discharge section (171c) may be provided in a downwardly inclined shape as it moves toward the front of the robot vacuum cleaner station (100). That is, the external air discharge section (171c) may be provided in a downwardly inclined shape as it moves away from the heater (171d). Accordingly, the end from which air is discharged from the external air discharge section (171c) may be formed to be inclined at a predetermined angle with respect to the ground. The angle at this time may be 90 degrees or less. Therefore, the external air discharge section (171c) may discharge air along a direction that intersects with the direction in which the flow guide surface (122c) is formed.

[0398] For example, an external air discharge port (171ca) may be formed in the external air discharge section (171c). The external air discharge port (171ca) may refer to an open portion of the external air discharge section (171c). The external air discharge port (171ca) may discharge air toward the cleaning plate (122). When the mop (242) is seated on the cleaning plate (122), the external air discharge section (171c) may be opened toward the upper side of the mop (242). Thus, the external air discharge section (171c) is positioned adjacent to the mop (242) and is open downward, so that air discharged from the external air discharge section (171c) can flow toward the mop (242).

[0399] Meanwhile, the outside air discharge port (171ca) may be penetrated by a virtual plane (C) including a virtual line connecting left and right points forming the maximum width of the blower fan (171e) and a blower fan axis (a1). The blower fan (171e) according to one embodiment of the present invention may be positioned in a tilted state. More specifically, the blower fan (171e) may be positioned tilted so that the surface where air is discharged faces the ground. Additionally, the outside air discharge section (171c) may be provided in a downwardly inclined shape as it moves away from the heater (171d). Accordingly, the plane (C) including the blower fan axis (a1) may be formed to penetrate the downwardly open outside air discharge port (171ca).

[0400] With this configuration, the path through which the air discharged from the blower fan (171e) reaches the mop (242) through the outside air outlet (171ca) can be shortened. Additionally, the speed of the heated air delivered to the mop (242) can be increased, thereby improving drying efficiency.

[0401] Meanwhile, the outside air discharge section (171c) may be equipped with a grille that guides the direction of air discharge. Through this, it is possible to prevent heated air from being discharged in a concentrated manner at a specific location.

[0402] A blower fan (171e) is positioned on an outside air supply path (171a) and can blow air toward a receiving space (S). The blower fan (171e) can provide flow to the air introduced through the outside air inlet (171b).

[0403] The blower fan (171e) can flow air to the outside air discharge section (171c). When the blower fan (171e) is driven, air introduced through the outside air inlet (171b) is heated by the heater (171d) and can be discharged into the receiving space (S) through the outside air discharge section (171c). The blower fan (171e) may be configured as an axial fan. The air discharge direction of the blower fan (171e) may be parallel to the rotation axis of the shaft. The air intake direction of the blower fan (171e) may be parallel to the air discharge direction.

[0404] Through this configuration, the airflow path can be simplified by aligning the intake and discharge directions of the airflow. Additionally, the same airflow volume can be provided even at a relatively low rotational speed. Therefore, compared to the case where the blower fan (171e) is composed of a centrifugal fan, there is an effect of being able to use a smaller size blower fan (171e). Accordingly, the space occupied by the blower fan (171e) can be minimized, and the number of required parts can be reduced.

[0405] A blower fan (171e) may be positioned between the rear surface (111b) of the housing (110) and the heater (171d). The blower fan (171e) may be positioned to have a certain inclination with respect to the rear surface (111b). The blower fan (171e) may be positioned at an inclination so that the side where air is discharged faces the ground.

[0406] Specifically, a virtual fan axis (a1) extending the shaft rotation axis of the fan (171e) can be inclined at a constant angle with the ground. The fan axis (a1) can be inclined at a constant angle with the rear surface (111b). One side of the fan axis (a1) passes through the outside air inlet (171b), and the other side passes through the heater (171d).

[0407] At least a portion of the blower fan (171e) may be spaced apart from the rear surface (111b). The blower fan (171e) may be positioned at a certain angle relative to the rear surface (111b). Accordingly, the distance between the top of the blower fan (171e) and the rear surface (111b) may be greater than the distance between the bottom of the blower fan (171e) and the rear surface (111b).

[0408] Meanwhile, if the maximum distance between the blower fan (171e) and the rear side (111b) is secured above a certain level, airflow can be formed smoothly. That is, the degradation of FMC (Fan Motor Control) performance can be minimized under the maximum output conditions of the heater. In particular, when the distance between the blower fan (171e) and the rear side (111b) is 30mm, the FMC performance degradation rate is maintained at -1.47%.

[0409] If the maximum gap between the blower fan (171e) and the rear surface (111b) is set to less than 25mm, air flow is not formed smoothly, and there is a high possibility that the air around the heater (171d) will become stagnant. Consequently, the temperature of the heater (171d) may rise above 112°C, and the temperature of the surface where air is discharged from the blower fan (171e) may also rise above 30°C, increasing the load on the blower fan (171e) and potentially causing a risk of overheating. Additionally, the temperature of the outside air outlet (171ca) may rise above 73°C, increasing the likelihood that air discharge will not be smooth.

[0410] If the maximum gap between the blower fan (171e) and the rear side (111b) exceeds 35mm, the distance from the rear side (111b) may become excessively large, which may reduce the air intake efficiency of the blower fan (171e). Specifically, as the air flow rate through the blower fan (171e) increases excessively, the heat transfer efficiency through the heater (171d) may decrease. Additionally, if the gap between the blower fan (171e) and the rear side (111b) becomes excessively wide, it becomes difficult to efficiently utilize the internal space of the housing (110), and the volume occupied by the mop drying section (170) may increase.

[0411] Accordingly, in a robot vacuum cleaner station (100) according to one embodiment of the present invention, the maximum distance between the blower fan (171e) and the rear surface (111b) can be set to 25mm or more and 35mm or less. This ensures the stability of the airflow and allows the temperature of the heater (171d) to be maintained at an appropriate level. Furthermore, the performance of the blower fan (171e) can be optimized.

[0412] A heater (171d) is positioned on an outside air supply channel (171a) and can heat the air flowing through the outside air supply channel (171a). The heater (171d) can heat the air introduced through the outside air inlet (171b). The heater (171d) can heat the air discharged through the outside air discharge section (171c).

[0413] The heater (171d) may include a heater housing and a heating element. In this case, the heater housing may be placed on an external air supply path (171a), and a space may be provided inside to accommodate a heating element. Additionally, the heating element may heat the air flowing into the heater housing. Thus, the air heated by the heating element is discharged into the receiving space (S) through the external air discharge section (171c) to dry the wet rag (242).

[0414] Air heated by heat discharged from the outside air supply module (171) can be discharged through the air discharge section (172).

[0415] The air exhaust section (172) may be positioned at least partially above the receiving space (S).

[0416] Air heated by heat discharged from the external air supply module (171) can supply heat to the mop (242) of the robot vacuum cleaner (200). Accordingly, moisture absorbed and remaining in the mop (242) can absorb heat from the air and vaporize. The vaporized moisture can flow within the receiving space (S). Therefore, the air within the receiving space (S) may contain vaporized moisture, and the humidity within the receiving space (S) may increase (hereinafter, the air containing vaporized moisture within the receiving space (S) may be referred to as 'moist steam').

[0417] The air exhaust section (172) can discharge air from within the receiving space (S) to the outside. Specifically, at least a portion of the air exhaust section (172) may be placed on the upper cover (113), and the upper cover (113) may cover the upper part of the receiving space (S).

[0418] The air heated by the heat discharged from the outside air supply module (171) vaporizes the moisture in the mop (242), so the humidity is increased. Therefore, when the robot vacuum cleaner station (100) is placed at the bottom of the kitchen cabinet (2), if the steam comes into contact with various parts of the kitchen cabinet (2), such as the baseboard (26), it will have an adverse effect on the parts.

[0419] In this embodiment, the upper cover (113) covers the upper part of the receiving space (S) and the door (126) covers the front of the receiving space (S), so the upper cover (113) together with the door (126) prevents the moisture from the receiving space (S) from escaping to the outside, thereby preventing the kitchen cabinet (2) from coming into contact with the moisture.

[0420] The air exhaust section (172) may include an air intake (172a), an air exhaust duct (172b), and an exhaust fan (172c).

[0421] The air intake (172a) may be connected to the receiving space (S). The air intake (172a) may be positioned above the receiving space (S). The moisture vapor in the receiving space (S) may be discharged through the air intake (172a). Air within the receiving space (S) may be drawn in through the air intake (172a).

[0422] The air intake (172a) can be positioned higher than the ground than the robot vacuum cleaner (200) when the robot vacuum cleaner (200) is seated on the seating portion (120). Through this, the efficiency of sucking up rising convective steam as the mop dries can be increased.

[0423] For example, an air intake (172a) may be formed in the upper cover (113). In this case, the upper cover (113) may be formed in a shape in which two or more plates are stacked, and the air intake (172a) may be formed in the inner cover (113b), which is the lowest plate among them, and a flow path communicating with the air intake (172a) may be formed between the inner cover (113b) and the outer cover (113a) to form an air discharge duct (172b).

[0424] Additionally, the air intake (172a) may be positioned higher than the outside air discharge (171ca) above the ground.

[0425] As another example, the air intake (172a) may be formed on a circular or square pipe-shaped air exhaust duct (172b), and the air exhaust duct (172b) may be connected to the upper cover (113).

[0426] With this configuration, when the upper cover (113) is separated, the air exhaust duct (172b) can be separated together with the upper cover (113), and when it is necessary to open the upper part of the robot vacuum cleaner station (100) for reasons such as repair, there is an advantage that the air exhaust duct (172b) can be removed by a simple motion of lifting the upper cover (113).

[0427] The air intake (172a) may be formed in the shape of a hole on the upper cover (113). The air intake (172a) may be in the shape of a circular hole. An exhaust fan housing may be directly connected to the hole portion of the air intake (172a). Through this, air drawn in through the air intake (172a) can flow immediately into the exhaust fan housing. Air drawn in through the air intake (172a) can be drawn into the exhaust fan (172c). The distance from the outside air discharge port (171c) to the air intake (172a) may be greater than the distance from the outside air discharge port (171c) to the mop (242). This is to prevent energy from being wasted by the heated air discharged from the outside air discharge port (171c) being drawn directly into the air intake (172a) without being sufficiently supplied to the mop (242).

[0428] Additionally, the air intake (172a) may be positioned closer to the door (131) than the outside air discharge (171c). Since the air intake (172a) is positioned at the front upper part of the receiving space (S), the range of the space through which the heat discharged from the outside air discharge section (171c) flows is widened, thereby improving the drying efficiency of the mop (242). Therefore, the heat discharged through the outside air discharge section (171c) flows forward to dry the mop (242) of the robot vacuum cleaner (200), and then can be discharged through the air intake (172a).

[0429] Additionally, the air intake (172a) may be positioned above the path where the robot vacuum cleaner (200) moves within the housing (110). This prevents condensation from forming on the inner wall of the housing (110).

[0430] For example, at least a portion of the air intake (172a) may be positioned vertically above the position where the left-right width of the robot vacuum cleaner (200) is greatest when the robot vacuum cleaner (200) is seated on the seating portion (120). That is, at least a portion of the air intake (172a) may be positioned above the position where the gap between the robot vacuum cleaner (200) and a pair of inner walls (124) is narrowest. At this time, at least a portion of the air intake (172a) may be positioned in front of the cleaning plate (122).

[0431] Through this, steam generated during the drying process of the mop (242) can be prevented from flowing toward the front of the robot vacuum cleaner station (100), and moisture can be prevented from penetrating the sensor placed in front of the robot vacuum cleaner (200) and causing a malfunction.

[0432] The air exhaust duct (172b) can connect the exhaust fan (172c) and the air outlet (172e) to the drain pipe (25) of the kitchen cabinet (2). The air exhaust duct (172b) can guide the steam discharged through the air intake (172a) to the drain pipe (25).

[0433] One side of the air exhaust duct (172b) may be connected to the air intake (172a) and the other side may be connected to the air exhaust (172e). An exhaust fan (172c) may be placed on the air exhaust duct (172b). An air exhaust passage may be formed inside the air exhaust duct (172b) that communicates with the air intake (172a).

[0434] The exhaust fan (172c) can flow air from the receiving space (S) to the air intake (172a). It can cause air flow from the air intake (172a) toward the drain pipe (25). The exhaust fan (172c) can generate air flow so that after drawing in the moisture from the receiving space (S) to the air intake (172a), it can discharge it to the outside through the air discharge duct (172b).

[0435] The exhaust fan (172c) may include an exhaust fan housing, a shaft, a fan motor, and an impeller. The exhaust fan housing may have an internal flow path formed to communicate with an air discharge duct (172b). When the exhaust fan motor is operated and the exhaust fan impeller rotates, air from the receiving space (S) or the housing (110) flows into the air discharge duct (172b), passes through the inside of the exhaust fan housing, and can be discharged through the air outlet (172e).

[0436] Meanwhile, in this embodiment, the exhaust fan (172c) may be positioned above the path where the robot vacuum cleaner (200) moves within the housing. For example, the exhaust fan (172c) may be positioned on the upper cover (113). The exhaust fan housing may be positioned between the outer cover (113a) and the inner cover (113b) included in the upper cover (113).

[0437] A virtual exhaust fan axis (a2) extending the shaft rotation axis included in the exhaust fan (172c) can be positioned perpendicular to the ground. That is, the air intake direction of the exhaust fan (172c) can be perpendicular to the ground.

[0438] Meanwhile, in this embodiment, the exhaust fan (172c) may be configured as a centrifugal fan. The air discharge direction of the exhaust fan (172c) may be perpendicular to the shaft rotation axis. The air intake direction of the exhaust fan (172c) may be perpendicular to the air discharge direction. When the exhaust fan (172c) is driven, air in the receiving space (S) may flow into the air intake port (172a). The air flowing into the air intake port (172a) may be exhausted through the drain pipe (25).

[0439] At this time, the air outlet (172e) may be formed in a shape that is open toward the rear of the housing (110). Condensation caused by the moisture discharged through the air outlet (172e) may collect along the inclined surface formed on the fitting joint (114) of the housing (110). The air discharged from the air outlet (172e) may diffuse into the outside air.

[0440]

[0441] Control configuration

[0442]

[0443] FIG. 15 discloses a block diagram for explaining the control configuration in a vacuum cleaner station according to an embodiment of the present invention.

[0444] Referring to FIG. 15, the control configuration of the robot vacuum cleaner station (100) of the present invention is described as follows.

[0464]

[0465] Frame

[0466]

[0467] In order for the robot vacuum cleaner station to be installed at the bottom of the kitchen cabinet (2), it is necessary to remove the pedestal (21) supporting the bottom of the kitchen cabinet (2) to secure space. However, if the pedestal (21) is removed, the kitchen cabinet (2) may sink downward due to its own weight.

[0468] In addition, there is a limitation in that it may be difficult for the user to retrieve and repair the robot vacuum cleaner if it malfunctions while tucked under a kitchen cabinet or if internal parts of the robot vacuum cleaner station break down.

[0469] To solve this, the present invention provides a frame (400) that supports the lower side of the kitchen cabinet (2) in place of the pedestal (21). That is, the present invention provides a frame (400) so that the housing (110) can be pushed in and assembled during installation, and the housing (110) can be pulled out for repair and parts replacement during repair.

[0470]

[0471] Referring to FIGS. 16 to 23, the structure of the frame (400) of the present invention is described as follows.

[0472] The robot vacuum cleaner station (100) may include a frame (400) installed on the lower side of the kitchen cabinet (2).

[0473] The frame (400) includes a pair of side walls (410) facing each other.

[0474] For example, a pair of side walls (410) may be installed at a predetermined distance from the lower side of the kitchen cabinet (2). The side walls (410) may support the lower side of the kitchen cabinet (2).

[0475] Specifically, a pair of side walls (410) can receive the load of the kitchen cabinet (2) through the upper lifter (430) described later, and can distribute and support the load applied through the upper lifter (430).

[0476] Accordingly, according to the present invention, a pair of side walls (410) support the lower surface of the kitchen cabinet (2), thereby preventing the kitchen cabinet (2) from sinking downwards in the absence of a pedestal (21).

[0477] Meanwhile, each side wall (410) may include a side wall body (411) and an upper support surface (412).

[0478] The side wall body (411) may be formed along a direction perpendicular to the ground. For example, the side wall body (411) may refer to a wall surface formed in a rectangular shape along a direction perpendicular to the ground. The side wall body (411) may be positioned at the outermost left and right sides of the robot vacuum cleaner station (100).

[0479] The upper support surface (412) can be formed by bending and extending from the top of the side wall body (411). For example, the upper support surface (412) can be formed by bending and extending from the top of the side wall body (411) toward the inside of the robot vacuum cleaner station (100) and can be formed along a direction parallel to the ground. Thus, the upper support surface (412) can be positioned to face the lower side of the kitchen cabinet (2).

[0480] An upper lifter (430) can be attached to the upper support surface (412). At this time, a lifter receiving portion in the form of a groove or hole may be formed on the upper support surface (412) to accommodate the upper lifter (430). Through this, when the height of the lower surface of the kitchen cabinet (2) is extremely low, the side wall (410) can directly contact and support the lower surface of the kitchen cabinet (2) without moving the upper lifter (430) upward.

[0481] The side wall (410) may further include a reinforcing surface (413). The reinforcing surface (413) may be formed by bending and extending at both ends of the side wall body (411) in the front-rear direction. For example, the reinforcing surface (413) may be formed by bending and extending from both ends of the side wall body (411) in the front-rear direction toward the inside of the robot vacuum cleaner station (100), and may be formed along a direction perpendicular to the ground. At this time, the upper end of the reinforcing surface (413) may be connected to the upper support surface (412). Thus, the reinforcing surface (413) can distribute the load applied to the side wall body (411) and prevent the side wall body (411) from being deformed by the load.

[0482] The frame (400) includes a frame connecting part (420).

[0483] The frame connecting part (420) can connect the lower ends of a pair of side walls (410) and be positioned to face the ground. For example, the frame connecting part (420) can be formed in the shape of a flat plate to connect the lower ends of a pair of side walls (410). Through this, the frame connecting part (420) can maintain the spacing between the pair of side walls (410). In addition, the frame connecting part (420) can support the lower side of the housing (110) from the ground when the housing (110) is connected. Through this, the housing (110) can be protected and stably supported even when the ground is uneven.

[0484] Meanwhile, the front-rear length of the frame (400) may be shorter than the front-rear length of the housing (110). That is, the front-rear length of the frame connecting part (420) may be shorter than the front-rear length of the housing (110). In this case, the part not supported by the frame connecting part (420) may be spaced apart from the ground at a predetermined distance. Therefore, even if the ground is uneven, the robot vacuum cleaner station (100) can maintain stable balance because it does not come into contact with the housing (110).

[0485] Meanwhile, according to an embodiment, a plurality of grooves may be formed in the frame connecting portion (420). This prevents deformation of the frame connecting portion (420).

[0486] The frame (400) further includes an upper lifter (430). The upper lifter (430) is movably connected to each of a pair of side walls (410) and can be supported in contact with the lower surface of the kitchen cabinet (2). Specifically, the upper lifter (430) can be movably connected to an upper support surface (412). For example, the upper lifter (430) can be connected to a member such as a nut so that when a worker rotates the upper lifter (430), it can be moved up and down relative to the upper support surface (412).

[0487] At this time, the gap between a pair of upper lifters (430) may be larger than the width of the rear housing (111b) to be described later.

[0488] Accordingly, according to the present invention, the lower surface of the kitchen cabinet (2) is supported through the upper lifter (430), thereby preventing the kitchen cabinet (2) without the pedestal (21) from sinking downwards.

[0489] Additionally, the frame (400) may further include lower lifters (440). One or more lower lifters (440) are connected to the lower side of the side wall (410) and can contact and support the ground. That is, more lower lifters (440) than upper lifters (430) can be connected to the side wall (410). The lower lifters (440) are connected to the frame connecting part (420) and can contact and support the ground. Specifically, the lower lifters (440) can be connected to the frame connecting part (420) so as to be movable up and down. For example, the lower lifters (440) are connected to a member such as a nut so that when a worker rotates the lower lifters (440), they can move up and down relative to the frame connecting part (420).

[0490] Accordingly, according to the present invention, the horizontal level of the frame connecting part (420) can be adjusted by adjusting the height of the lower lifter (440).

[0491] That is, according to the present invention, the housing (110) can be leveled by the frame (400), and at the same time, the housing (110) can be leveled regardless of whether the ground is uneven.

[0492] Additionally, the frame (400) may further include an inner frame (450) that is coupled to a pair of side walls (410) to reinforce the side walls (410). Specifically, the inner frame (450) is positioned between the upper support surface (412) and the frame connection part (420) and can reinforce the side walls (410).

[0493] The inner frame (450) can be placed inside the side wall (410) to fill the internal space of the side wall (410). For example, the inner frame (450) may be formed in a cuboid shape overall, but the internal structure may be formed in a grid shape. Through this, the effect of dispersing the load applied to the side wall (410) can be maintained while minimizing the increase in overall weight.

[0494] Meanwhile, a guide portion (451) that guides the movement of the housing (110) may be formed on the side wall (410) or the inner frame (450). Specifically, the guide portion (451) may be formed by being recessed along the front-rear direction on the inner surface of the side wall (410) or the inner frame (450). For example, the guide portion (451) may be a guide groove formed along the front-rear direction. The guide portion (111c) of the front housing (111) may be accommodated in the guide portion (451).

[0495] Meanwhile, in the present invention, the guide portion (451) of the frame (400) is not limited to a recessed shape, but may be a rail shape corresponding to the shape of the guide portion (111c) of the housing.

[0496] With this configuration, the housing (110) can be withdrawn from the frame (400) along the guide section (451) or inserted along the guide section (451).

[0497]

[0498] Meanwhile, referring to FIGS. 16 to 23, the method of installing the robot vacuum cleaner station of the present invention is described as follows.

[0499] The kitchen cabinet (2) can be supported through four pedestals (21). Specifically, two pedestals (21a) may be provided at the lower front of the kitchen cabinet (2), and two pedestals (21b) may be provided at the lower rear. In this way, the kitchen cabinet (2) can be supported through four-point support.

[0500] Under these conditions, the installation method of a robot vacuum cleaner station according to an embodiment of the present invention includes a pedestal separation step (S10), a frame installation step (S20), a height adjustment step (S30), a power supply and fluid path connection step (S40), a housing assembly step (S50), and a housing coupling step (S60).

[0501] The pedestal separation step (S10) can be performed when the spacing between a pair of pedestals (21a) positioned at the front of the lower surface of the kitchen cabinet (2) is smaller than the width of the front housing (111a). In the pedestal separation step (S10), after the worker separates the baseboard (26), the pedestals (21a) supporting the kitchen cabinet (2) can be removed to secure space for installing the frame (400).

[0502] At this time, the worker may remove only the pair of pedestals (21a) positioned at the front among the four pedestals (21a) supporting the lower side of the kitchen cabinet (2) and not remove the pair of pedestals (21b) positioned at the rear. This is because the width of the rear housing (111b) is smaller than the spacing of the pair of pedestals (21b) positioned at the rear.

[0503] Afterwards, in the frame installation step (S20), the worker can push the frame (400) into the lower space of the kitchen cabinet (2) from which the pedestal (21a) has been removed.

[0504] At this time, in the present invention, the front-rear length of the frame (400) is formed to be shorter than the front-rear length of the housing (110) so that the rear end of the frame (400) can be prevented from interfering with a pair of pedestals (21b) positioned at the rear.

[0505] Afterwards, in the height adjustment step (S30), the worker can adjust the height of the lower lifter (440) provided on the side wall (410) to be level with the ground, and adjust the height of the upper lifter (430) to make contact support with the lower surface of the kitchen cabinet (2).

[0506] At this time, the operator can adjust the height by rotating the upper lifter (430) and / or lower lifter (440), and can fix the height of the upper lifter (430) and / or lower lifter (440) through nuts (414, 452) provided on the side wall (410) and the inner frame (450).

[0507] Afterwards, in the power and Euro connection step (S40), the operator can connect the power and hose to the robot vacuum cleaner station (100).

[0508] Specifically, the operator can connect a wire to a power connection (111ba) located at the rear of the housing body (111). Additionally, the operator can connect a hose for supplying purified water and / or a hose for discharging wastewater to fittings (111bb, 111bc). Additionally, although not illustrated, a hose can be connected to discharge steam generated during the process of washing and drying the mop (242).

[0509] At this time, the housing (110) may have the upper cover (113) separated to connect the fitting part (111bb, 111bc) and the hose.

[0510] Generally, the power outlet, water supply pipe, and drain pipe may be placed inside the kitchen cabinet (2) or between the kitchen cabinet (2) and the wall of the building. In this case, the power connection part (111ba) and fitting part (111bb, 111bc) are gathered at the rear side of the rear housing (111b). Accordingly, for connection to the robot vacuum cleaner station (100), the operator can easily connect the power wire connected to the power and the hose connected to the water supply pipe and / or drain pipe to the rear lower side of the kitchen cabinet (2) to the robot vacuum cleaner station (100).

[0511] In the housing assembly step (S50), the worker can assemble the housing (110) for the installation of the robot vacuum cleaner station (100). At this time, the worker can cover the upper side of the housing body (111) with an upper cover (113).

[0512] Afterward, in the housing assembly step (S60), the operator can align the guide rail (111c) formed on the housing body (111) with the guide part (451) provided on the frame (400) and push the housing body (111) backward. Through this process, the operator can easily install the robot vacuum cleaner station (100).

[0513] Accordingly, according to the present invention, the robot vacuum cleaner station (100) can be installed by a simple process of removing only the front pedestal (21a) and not removing the rear pedestal (21b), which is difficult for a worker to reach, and pushing in the housing (110).

[0514] Therefore, the present invention has the effect of allowing a robot vacuum cleaner station (100) to be installed by utilizing the lower space of the kitchen cabinet (2).

[0515] In addition, the housing can be installed by a simple process of connecting a hose and wires to the rear of the housing (110) while the housing is pulled out of the kitchen cabinet (2) and then pushing it into the frame (400).

[0516]

[0517] On the other hand, when maintenance such as repair or cleaning is required for the robot vacuum cleaner station (100), the frame (400) is fixedly connected to the kitchen cabinet (2), and the user or worker can pull the housing body (111) forward from the frame (400).

[0518] At this time, the housing body (111) can be withdrawn with the seating portion (120) provided inside. With this configuration, when the housing body (111) is withdrawn, the seating portion (120) and / or the robot vacuum cleaner (200) can be withdrawn from the kitchen cabinet (2) to the outside.

[0519] At this time, when the housing body (111) is withdrawn, the upper cover (113) may be exposed to the outside. At this time, a worker or user may detach the upper cover (113) along a direction that intersects with the direction in which the housing body (111) is withdrawn from the frame (400). For example, a user or worker may detach the upper cover (113) by moving it upward. As a result, the robot vacuum cleaner (200) may be exposed to the outside.

[0520] Accordingly, according to the present embodiment, a user of the robot vacuum cleaner station (100) can pull the housing body (111) to expose the internal components of the robot vacuum cleaner station (100) or the robot vacuum cleaner (200).

[0521] In addition, when inspection or repair is required, the housing (110) can be removed from the frame (400) and only the upper cover (113) needs to be lifted, which has the effect of making replacement and repair of parts easy.
