Description

Robot Vacuum Station

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

[0002] With recent advancements in industrial technology, robot vacuum cleaners are being developed that can move around and clean areas that require cleaning on their own without user intervention.

[0003] These robot vacuum cleaners are equipped with sensors that can recognize the space to be cleaned, an agitator that can sweep the floor, and a mop that can wipe the floor. They can drive while sucking up dust on the floor in the space recognized by the sensor and wiping it with a mop, etc.

[0004] Among robot vacuum cleaners, there are dry robot vacuums that can suction and remove debris scattered on the floor, and wet robot vacuums that can wipe the floor with a moist mop to effectively remove debris attached to the floor. Dry robot vacuums are equipped with a dustbin and use the suction power of a suction motor to suck up debris from the floor. Wet robot vacuums are equipped with a water tank, and the water contained in the water tank is supplied to the mop, which wipes the floor while still moist, effectively removing debris attached to the floor. There are also robot vacuums that are equipped with both an agitator and a mop.

[0005] A robot vacuum cleaner's charging station is a device that docks the robot vacuum cleaner after cleaning and supplies power to the battery, charging it. The charging station has a power supply module inside. The charging station has a charging terminal connected to the power supply module, and the robot vacuum cleaner has a corresponding terminal. When the charging terminal and the corresponding terminal make contact, power is supplied to the battery, charging it.

[0006] Meanwhile, if a robot vacuum cleaner charging station is placed indoors, it will occupy a certain portion of the interior space. This can reduce indoor space efficiency. Furthermore, users or pets passing by may collide with the robot vacuum cleaner, resulting in injury to the user or pet, as well as damage to the robot vacuum.

[0007] Additionally, in the case of stations with added dust collection functions for robot vacuum cleaners, there is a limit to how much they can damage the interior of a room as the volume they occupy increases.

[0008] In this regard, Chinese Utility Model Registration No. CN 218922467 U discloses a cleaning station in which a robot cleaner is combined with the lower part of a washing machine to charge the robot cleaner, collect dust, and wash the mop of the robot cleaner.

[0009] However, the above-mentioned cleaner station has an open space formed at the bottom of the washing machine into which a robot cleaner can enter, a detergent and water supply device for washing a mop is provided at the vertical upper side of the space into which the robot cleaner enters, and a dust bag is placed on the side of the space into which the robot cleaner enters.

[0010] In this arrangement, the height of the overall cleaner station increases, so there is a limitation in that it cannot be installed using the space underneath the furniture, including the sink.

[0011] In addition, since the above-mentioned cleaner station must be installed at the bottom of the washing machine, a space for installing the washing machine must be provided, and there is a limitation that an installation space with a height exceeding the height of the washing machine itself as well as the height of the cleaner station must be provided.

[0012] In addition, since the above-mentioned vacuum cleaner station always has an open space where the robot vacuum cleaner enters and exits, there is a limitation that dust may fly during the process of collecting dust in the robot vacuum cleaner's dust bin, and that wastewater may leak during the process of washing the robot vacuum cleaner's mop.

[0013] Meanwhile, the above-mentioned cleaning station is equipped with a washing tank for washing the mop, but does not have a structure for separately withdrawing and managing the washing tank.

[0014] In this case, foreign substances contained in the wastewater can accumulate in the washing tank, causing an unpleasant odor. Furthermore, there is the risk of re-contaminating mops placed close to the washing tank.

[0015] In order to resolve this issue, the above-mentioned cleaner station has the inconvenience of having to disassemble the cleaner station from the washing machine and manage the washing tub separately.

[0016] Meanwhile, Chinese Utility Model CN ​​218588948 U discloses a station including a washing plate for washing the mop of a robot vacuum cleaner.

[0017] The above-described washing plate is configured to wash the mop by friction with the mop. At this time, the wastewater used for washing can be stored in a washing tank located below the washing plate.

[0018] However, the above station has a limitation in that only the washing plate can be separated, and the washing tank cannot be separated from the station body.

[0019] In such cases, there is the inconvenience of the user having to lift the station body or lie down on the floor to manage the washing tank.

[0020] The present invention was created to improve the problems of the conventional robot vacuum cleaner station as described above, and its purpose is to provide a robot vacuum cleaner station that can be built into the lower part of a kitchen cabinet without providing a separate installation space.

[0021] Additionally, the purpose is to provide a robot cleaner station capable of accommodating a robot cleaner in the lower space of a kitchen cabinet having a predetermined height restriction.

[0022] In addition, when a robot vacuum cleaner is combined, the purpose is to provide a robot vacuum cleaner station that can automatically collect dust in the dust bin of the robot vacuum cleaner.

[0023] Additionally, when a robot vacuum cleaner is combined, the purpose is to provide a robot vacuum cleaner station that can automatically wash the mop of the robot vacuum cleaner.

[0024] In addition, the purpose is to provide a robot vacuum cleaner station that can automatically dry the mop after washing the mop of the robot vacuum cleaner.

[0025] Additionally, the purpose is to provide a robot vacuum cleaner station that can be withdrawn for cleaning and repair as needed.

[0026] In addition, the purpose is to provide a robot cleaner station that can separately withdraw and manage the base that may become contaminated during the mop washing process.

[0027] Additionally, the purpose is to provide a robot cleaner station that prevents wastewater collected in the cleaning tank from leaking out by combining the separated base at the exact location.

[0028] In addition, the purpose is to provide a robot cleaner station that facilitates separation and attachment of the base.

[0029] In order to achieve the above-described purpose, the robot cleaner station according to the present invention includes a housing arranged at the bottom of a kitchen cabinet; and a base supporting the bottom of the robot cleaner and retractably coupled to the housing; and a handle may be formed on the upper surface of the base.

[0030] Meanwhile, the handle may include a recessed portion formed in the base.

[0031] In addition, it may include a cover portion that is formed to protrude rearward from the front end of the recessed portion and is formed to cover at least a portion of the recessed portion.

[0032] Additionally, the shape of the handle may be an oval with a width in the left-right direction greater than a width in the front-back direction.

[0033] Meanwhile, the base includes an agitator receiving portion in which the agitator of the robot cleaner is received, and the handle may be positioned in front of the agitator receiving portion.

[0034] In addition, the base includes an auxiliary wheel guide portion in which an auxiliary wheel of the robot cleaner is accommodated; and the handle can be arranged between the agitator accommodation portion and the auxiliary wheel guide portion.

[0035] Through this, the user can easily separate and combine the base.

[0036] In addition, the base includes a pair of wheel guide parts that guide movement of the wheels of the robot cleaner, and the handle can be placed between the pair of wheel side parts.

[0037] Meanwhile, the housing may include a door that can be opened and closed to allow the robot cleaner to enter and exit; and a door frame that is arranged on the front of the housing and to which the door is hinged; and the lower portion of the door frame may include an inclined guide surface that forms a downward slope from the front end of the housing to the rear end and guides the movement of the base.

[0038] Additionally, the base may include a lower inclined portion formed to move in contact with the inclined guide surface at the bottom.

[0039] In addition, the base may include a base bottom surface facing the bottom surface of the housing; and a base wall formed to extend vertically from the base bottom surface; and a fixing groove formed recessed in the base wall and detachably fixing the base to the housing.

[0040] Meanwhile, the housing may include a base fixing protrusion formed to protrude forward and accommodated in the fixing groove.

[0041] In addition, the housing may further include a wastewater suction nozzle through which fluid is discharged on the bottom surface of the base; and the base may include a nozzle insertion port formed on the base wall and through which the wastewater suction nozzle is inserted to secure the base to the housing.

[0042] Through this, the separated base can be joined in the correct position to prevent the wastewater collected in the washing tank from leaking out.

[0043] Meanwhile, it may include a washing plate that comes into contact with the mop of the robot vacuum cleaner and is detachably connected to the upper part of the base.

[0044] Additionally, the washing plate may include a washing plate grip portion formed to protrude forward.

[0045] Through this, the user can easily detach the cleaning plate from the base and wash it separately.

[0046] As described above, according to the robot cleaner station according to the present invention, a module capable of charging the robot cleaner, collecting dust, and washing the mop is arranged in a horizontal direction with the robot cleaner, thereby having the effect of utilizing the lower space of the kitchen cabinet.

[0047] In addition, the charging terminal, dust collection unit, mop washing unit, and mop drying unit are arranged in a way that surrounds the robot cleaner, which has the effect of enabling the robot cleaner to perform various functions simultaneously.

[0048] In addition, the washing water supply unit, washing plate, washing tank, wastewater discharge path, external air supply module, and power supply module are centrally placed at the rear of the robot cleaner's mop, which has the effect of enabling both washing and drying of the mop within a limited space.

[0049] Additionally, since all sides except the front are covered by kitchen cabinets, it has the effect of providing users with an aesthetically pleasing interior.

[0050] In addition, when a robot vacuum cleaner is combined, the dust inside the robot vacuum cleaner's dust bin is automatically collected, so the user only needs to take out the dust bag at regular intervals, which has the effect of reducing the user's effort.

[0051] Additionally, when a robot vacuum cleaner is combined, the robot vacuum cleaner's mop can be automatically washed, reducing the hassle of having to separate the mop and wash it separately.

[0052] Additionally, since detergent can be added as needed, it has the effect of increasing the cleaning effect of the mop.

[0053] Additionally, since the mop is washed using the kitchen water supply and drain pipes, it reduces the hassle of the user having to separately add water or drain wastewater.

[0054] In addition, after washing the mop of the robot vacuum cleaner, it can automatically dry the mop by supplying hot air to the mop and then discharge it, which has the effect of preventing the generation of bad odors.

[0055] Additionally, during the process of drying the mop, the air after drying is discharged downstream of the uretrap, which has the effect of preventing bad odors from flowing back.

[0056] Additionally, when the robot cleaner enters the robot cleaner station, the door of the robot cleaner station closes, which has the effect of preventing dust from flying outside while the dust bin is being collected.

[0057] Additionally, when washing the mop of a robot vacuum cleaner, it has the effect of preventing wastewater from leaking outside.

[0058] Additionally, the base is designed to be easily detached and reattached, allowing users to easily withdraw and retract the base.

[0059] Additionally, by combining the separated bases in the correct positions, it is possible to prevent wastewater collected in the washing tank from leaking out.

[0101]

[0102] Kitchen cabinetry and vacuum system

[0103]

[0104] FIG. 1 is a drawing for explaining a state in which a cleaning system according to an embodiment of the present invention is installed on the lower side of a kitchen cabinet, and FIG. 2 is a drawing for explaining a relationship in which a pipe of a cleaning system according to an embodiment of the present invention is connected to a drain pipe.

[0105] The cleaning system (1) according to an embodiment of the present invention may be installed on the lower side of a kitchen cabinet (2). Specifically, the kitchen cabinet (2) is placed in a kitchen and can store dishes, plates, cups, etc., and can provide a space for cooking food or washing dishes.

[0106] Additionally, the kitchen cabinet (2) may be equipped with a worktop that can serve as a sink, cooking surface, or work surface.

[0107] For example, a kitchen cabinet (2) may include a sink on the countertop, providing a space for washing dishes. Alternatively, the kitchen cabinet (2) may include a cooking surface for performing cooking tasks. Furthermore, the kitchen cabinet (2) may include a gas range, an induction range, or a stovetop on which a highlighter or oven is installed.

[0108] In general, a kitchen cabinet (2) with a width of 600 mm in the front-back direction and a width of 600 mm in the left-right direction can be used.

[0109] A cleaning system (1) according to another embodiment of the present invention may be provided on the lower side of a structure including at least one of a water supply pipe and a drain pipe. Specifically, the water supply pipe may refer to a conduit connected to an external water source that supplies fluid to the structure, and the drain pipe may refer to a conduit that discharges fluid discharged from the structure into a sewer.

[0110] A storage space for storing dishes and kitchen tools, etc., may be provided at the bottom of the kitchen cabinet (2) or the structure. That is, the kitchen cabinet (2) or the structure may include a top plate (22) that provides a space for cooking or washing dishes, a lower plate (23) that is arranged at a predetermined height from the ground, and a storage space formed between the top plate (22) and the lower plate (23) to store dishes and kitchen tools, etc. In this case, when the kitchen cabinet (2) is a sink, a sink (22a) may be arranged on the top plate (22).

[0111] Additionally, the lower plate (23) may be supported by a pedestal (21). The pedestal (21) is positioned perpendicular to the kitchen floor and may support the load of the kitchen cabinet (2).

[0130]

[0131] Meanwhile, FIGS. 6 to 9 disclose drawings for explaining a robot cleaner in a robot cleaner system according to an embodiment of the present invention.

[0132] The structure of the robot vacuum cleaner (200) is described below with reference to FIGS. 6 to 9.

[0133] A robot vacuum cleaner (200) can automatically clean an area to be cleaned by driving on its own in the area to be cleaned and sucking up foreign substances such as dust from the floor.

[0134] The robot cleaner (200) according to an embodiment of the present invention is configured to clean the floor while being placed on the floor and moving along the floor surface. Accordingly, the following description will be made with the up-down direction defined based on the state in which the robot cleaner (200) is placed on the floor.

[0135] And, based on a pair of wheels (260), the side where the auxiliary wheel (270) to be described later is placed is set as the front, and the side where the rotary cleaner (240) to be described later is placed is set as the rear.

[0136] The 'lowest part' of each configuration described in the embodiment of the present invention may be the part that is positioned lowest in each configuration when the robot cleaner (200) according to the embodiment of the present invention is used while placed on the floor, or may be the part closest to the floor.

[0137] A robot vacuum cleaner (200) according to an embodiment of the present invention comprises a body (210), a dust bin (220), a water bin (230), a rotating cleaning part (240), an agitator (250), a wheel (260), an auxiliary wheel (270), and a charging terminal (280).

[0138] The body (210) can form the overall exterior of the robot cleaner (200). Each component of the robot cleaner (200) can be combined into the body (210), and some components of the robot cleaner (200) can be accommodated inside the body (210).

[0139] Specifically, the body (210) may have components of the robot cleaner (200) installed in the internal space. For example, the body (210) may accommodate a battery and at least one motor in the internal space.

[0140] In an embodiment of the present invention, the body (210) may be formed in a form in which the width (or diameter) in the horizontal direction (parallel to X and Y) is greater than the height in the vertical direction (parallel to Z). Such a body (210) may help the robot cleaner (200) to have a stable structure and may provide a structure that is advantageous in avoiding obstacles when the robot cleaner (200) moves (drives).

[0141] When viewed from above or below, the body (210) can be formed in various shapes, such as circular, oval, or square.

[0142] The body (210) can be divided into a lower body and an upper body, and the lower body and the upper body can be combined to form a space inside.

[0143] The lower body can be joined to the upper body to form a space that can accommodate a battery, at least one sensor, and at least one motor therein.

[0144] The lower body may be formed with an intake (211) for air intake and a hole for accommodating a pair of wheels (260).

[0145] The suction part (211) may be a passage through which dust from the floor surface is drawn in. In addition, the suction part (211) may be connected to a suction path (not shown) formed inside the body (210), and the suction path may be connected to the internal space of the dust bin (220).

[0146] Meanwhile, the lower body may further be equipped with an exhaust path. One side of the exhaust path may be connected to the internal space of the dustbin (220), and the other side may be connected to an exhaust port. At this time, a filter may be placed in the exhaust port.

[0147] With this configuration, air drawn in through the suction part (211) can flow into the dust bin (220) through the suction path and be discharged to the exhaust port through the exhaust path.

[0148] An agitator (250), which will be described later, can be rotatably accommodated in the suction unit (211). With this configuration, dust around the suction unit (211) can be guided into the suction unit (211) by the rotation of the agitator (250), thereby increasing the efficiency of suctioning dust.

[0149] The upper body may form the upper exterior of the robot vacuum cleaner (200). Although not shown, the upper body may be equipped with a display.

[0150] The robot cleaner (200) of the present invention may include a bumper. The bumper is coupled along the edge of the body (210) and is configured to move relative to the body (210).

[0151] The bumper may be coupled along a portion of the edge of the body (210), or may be coupled 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 relatively toward 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 shock applied to the bumper, thereby preventing and reducing the shock from being transmitted to the body (210).

[0152]

[0153] A dust bin (220) may be provided to suck in external dust and air and store the dust.

[0154] The dust bin (220) can store dust that flows in through the suction passage. The dust bin (220) can be formed with a dust inlet that communicates with the suction passage, an internal space that can store dust, and an air outlet through which air can be discharged.

[0155] 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 may be provided in a detachable manner according to an embodiment.

[0156] Meanwhile, in the present invention, a dust discharge path may be formed in the dust bin (220). The dust discharge path may connect the internal space of the dust bin (220) with the external space of the robot cleaner (200). With this configuration, when dust is collected through the robot cleaner station (100), the dust inside the dust bin (220) may be removed.

[0157] Meanwhile, a dust discharge port (221) communicating with the dust discharge path may be formed in the dust bin (220) according to an embodiment of the present invention. For example, the dust discharge port (221) may be formed on one side of the rear of the outer surface (or outer circumference) of the body (210). As another example, the dust discharge port (221) may be formed on the outer surface of the dust bin (220).

[0158] In addition, the robot cleaner (200) according to an embodiment of the present invention may be provided with a dust bin door (222) that can selectively open and close the dust outlet (221). Specifically, the dust bin door (222) may be coupled to the body (210) and positioned so as to block the dust outlet (221). For example, the dust bin door (222) may be formed of a rubber or resin material and provided in a flip-able manner so that one side may be fixedly coupled to the body (210).

[0159] With this configuration, when the dust collecting motor (145) of the robot cleaner station (100) described later is operated, the dust bin door (222) is elastically deformed by the driving force of the dust collecting motor (145), and the dust discharge port (221) is opened, so that dust inside the dust bin (220) can be collected by the dust collecting unit (140) of the robot cleaner station (100).

[0160]

[0161] The water tank (230) is formed in the form of a container having an internal space for storing a liquid such as water. The water tank (230) is placed inside the body (210), and may be fixedly connected to the body (210), or may be detachably connected to the body (210).

[0162] 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) via a water supply hose.

[0163] At this time, the supply unit (231) may be placed on the opposite left and right sides of the robot cleaner (200) in relation to the dust discharge port (221). For example, if the dust discharge port (221) is placed on the rear left side of the body (210), the supply unit (231) may be placed on the rear right side of the body (210).

[0164] Through this configuration, when the robot cleaner (200) is coupled to the robot cleaner station (100), the robot cleaner station (100) can simultaneously perform dust collection and water injection.

[0165] Meanwhile, the nozzle (not shown) is formed in the form 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 the inside thereof. The nozzle (not shown) is arranged so that one end is connected to the water tank (230) and the other end is positioned on the upper side or on the rotating plates of a pair of rotating plates (241), thereby allowing the liquid inside the water tank (230) to be supplied to each of the pair of mops (242).

[0166] That is, the nozzle (not shown) may be formed in the form of a single pipe branched into two, and at this time, 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.

[0167] Meanwhile, although not shown, the water tank (230) is equipped with a pump to cause the water inside the water tank (230) to flow to a nozzle (not shown). Therefore, when the pump of the water tank (230) is operated, the liquid stored in the water tank (230) can be discharged to the rotating cleaning unit (240) through the nozzle (not shown).

[0168]

[0169] The rotary cleaner (240) includes a rotary plate (241) and a mop (242).

[0170] The turntable (241) may be provided as a pair including a left turntable and a right turntable, and the mop (242) may be provided as a pair including a left mop and a right mop.

[0171] The turntable (241) can be rotatably placed on the bottom surface of the body (210), and a mop (242) can be coupled to the lower side.

[0172] The turntable (241) is formed to have a predetermined area and is formed in the form of a flat plate or a flat frame. The turntable (241) is generally laid horizontally, and accordingly, the horizontal width (or diameter) is formed in a form sufficiently larger than the vertical height. The turntable (241) coupled to the body (210) may be parallel to the bottom surface (B), or may be inclined with the bottom surface (B). The turntable (241) may be formed in the form of a circular plate, the bottom surface of the turntable (241) may be generally circular, and the turntable (241) may be formed in an overall rotationally symmetrical form.

[0173] A pair of rotating plates (241) can be symmetrical to each other.

[0174] The mop (242) can be attached to the lower side of the turntable (241) so as to face the floor surface (B).

[0175] The mop (242) is formed so 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 so that the horizontal width (or diameter) is sufficiently larger than the vertical height. When the mop (242) is coupled to the body (210), the bottom surface of the mop (242) may be parallel to the floor surface (B), or may be inclined with the floor surface (B).

[0176] The bottom surface of the mop (242) may be generally circular, and the mop (242) may be formed in an overall rotationally symmetrical shape. In addition, the mop (242) may be detachably attached to the bottom surface of the turntable (241), and may be coupled to the turntable (241) and rotate together with the turntable (241).

[0177] Meanwhile, although not shown, the rotary cleaning unit (240) may be equipped with a driving unit that applies rotational force to the rotary plate (241). For example, the driving unit may include a motor and at least one gear. Accordingly, when the driving unit is operated, the rotary plate (241) and the mop (242) rotate to clean the floor surface.

[0178]

[0179] The agitator (250) is equipped with a plurality of rotatable 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.

[0180] Meanwhile, the agitator (250) according to the present embodiment receives rotational power from a separate agitator motor (not shown) installed therein, and may also receive rotational power from a driving motor according to the embodiment, and may also receive rotational power from a driving unit of a rotational cleaning unit (240).

[0181]

[0182] 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).

[0183] The wheel (260) is provided on the body (210) and can roll on the floor surface.

[0184] The wheel (260) may be composed of a first driving wheel and a second driving wheel. At this time, 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 cleaner (200), the second driving wheel may be located on the right side of the robot cleaner (200), and at this time, the first driving wheel and the second driving wheel may be symmetrical to each other.

[0185] The driving unit (not shown) may include a driving motor and a gear. In this case, the driving motor may be housed within the body (210) and provide power to the wheel (260). The driving motor may include a first driving motor and a second driving motor.

[0186] The driving motor may be an electric motor. A plurality of gears are configured to mesh with each other and rotate, 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 rotational axis of the driving motor rotates.

[0187] 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.

[0188] 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 minimize friction between the robot cleaner (200) and the floor surface while simultaneously guiding the movement of the robot cleaner (200).

[0189] A suction motor (not shown) can generate suction force to suck in external dust and air through a suction unit (211). For example, the suction motor (not shown) may be an electric motor. By the suction force generated by the suction motor (not shown), external dust and air can be drawn into the suction unit (211) and, after passing through the suction path, can reach the dust bin (220).

[0190] Although not shown, the battery is coupled to the body (210) to supply power to other components of the robot cleaner (200). The battery may supply power to at least one motor provided in the robot cleaner (200). For example, the battery may supply power to the motors provided in the rotating cleaner (240), the agitator (250), the wheels (260), and the suction motor (not shown).

[0191] Additionally, the battery can supply power to the sensor unit (not shown) and the control unit (not shown).

[0192] 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 arranged on the rear side of the outer surface of the body (210). When the robot cleaner (200) is connected to the robot cleaner station (100), the charging terminal (280) may be supplied with power by coming into contact with the power supply terminal (123b) of the robot cleaner station (100).

[0194] Robot Vacuum Station

[0195]

[0196] FIG. 10 is a perspective view illustrating a robot cleaner station according to an embodiment of the present invention, and FIG. 11 is a plan view of FIG. 10.

[0197] Referring to FIGS. 10 and 11, the robot cleaner station (100) of the present invention is described as follows.

[0198] A robot cleaner (200) can be accommodated in a robot cleaner station (100). A robot cleaner (200) can be coupled to a mounting portion (120) of the robot cleaner station (100).

[0199] The robot vacuum cleaner station (100) may include a housing (110).

[0200] The housing (110) may form the exterior of the robot cleaner station (100). For example, the housing (110) may be formed in a shape similar to a hexahedron including at least one outer wall surface.

[0201] The housing (110) may have a space formed therein that can accommodate a mounting portion (120), a dust collection path (130), a dust collection portion (140), a dust collection motor (145), a mop washing portion (160), a mop drying portion (170), and a circulation path.

[0202] 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 side plate (23) of the kitchen cabinet (2) and the floor of the kitchen.

[0203] The housing (110) includes a pair of outer walls (111) facing each other. The outer walls (111) may refer to a surface formed along the direction of gravity.

[0204] For example, a pair of outer walls (111) may be installed at a predetermined interval on the lower side of the kitchen cabinet (2). As another example, the housing (110) may further include a bottom surface facing the floor of the kitchen, and the pair of outer wall surfaces may be connected through the bottom surface. As another example, the housing (110) may further include a bottom surface facing the floor of the kitchen and an upper surface (113) facing the lower plate (23) of the kitchen cabinet (2), and the upper and lower ends of the pair of outer walls (111) may be connected to each other through the bottom surface and the upper surface (113). Therefore, even if foreign substances fall downward from the kitchen cabinet (2), the components of the robot cleaner (200) and the robot cleaner station (100) may be prevented from being contaminated. As another example, the housing (110) may further include the bottom surface, the upper side surface (112), and a rear surface (111b) facing the wall of the building.

[0205] With this configuration, components of the robot cleaner station (100) can be accommodated inside the housing (110) (between a pair of outer wall surfaces).

[0206] Additionally, a robot cleaner (200) may be accommodated inside the housing (110). The housing (110) may be arranged so that a pair of outer walls (111) have a gap greater than the maximum horizontal width of the robot cleaner (200). With this configuration, the robot cleaner (200) may enter and exit inside the housing (110).

[0207] At this time, in this embodiment, the robot cleaner (200) can enter and exit from the front of the robot cleaner station (100). Here, the front may mean the direction in which the door (126) is provided based on the interior of the robot cleaner station (100).

[0208] Additionally, the rear may mean the opposite direction of the front based on the interior of the robot cleaner station (100). For example, a building wall (not shown) may be placed at the rear of the robot cleaner station (100).

[0209] Additionally, when looking forward from inside the robot cleaner station (100), the left side can be called the left room and the right side can be called the right room.

[0210] That is, the outer wall (111) of the robot cleaner station (100) can be placed on the left and right sides, respectively.

[0211] Accordingly, the upper side of the housing (110) may be covered by the kitchen cabinet (2), and the lower side of the housing (110) may be covered by the kitchen floor. In addition, the left and right sides of the housing (110) are covered by the outer wall, but are placed at the lower part of the kitchen cabinet (2). At this time, the lower part of the kitchen cabinet (2) is finished by a baseboard except for the robot cleaner station (100), so that as a result, only the front of the housing (110) may be exposed to the outside.

[0212] Through this, the exposure of the robot cleaner station (100) and the robot cleaner (200) to the outside can be minimized.

[0213] With this configuration, the robot cleaner station (100) of the present invention has the effect of providing an aesthetic appeal to the user in terms of interior design.

[0214] Meanwhile, although not shown, the housing (110) may be provided with a space through which a water supply hose connected to a water supply pipe passes, a space through which a drain hose for discharging wastewater generated after washing a mop (242) passes, and a space through which a hose for discharging moisture generated during the drying process of a mop (242) passes. For example, a space through which the above hoses can pass may be provided in at least one of the outer wall (111) and the upper side (112) of the housing (110).

[0218] *

[0219] As illustrated in FIG. 11, the robot cleaner station (100) may include a mounting portion (120).

[0220] The robot cleaner (200) and the robot cleaner station (100) can be physically, electrically and / or axially connected through the mounting portion (120).

[0221] The fixing member (120) can be placed inside the housing (110).

[0222] At this time, depending on the embodiment, the mounting portion (120) may be provided so as to be withdrawable from the housing (110) through a drawer (190).

[0223] With this configuration, when the mounting part (120) needs to be cleaned or repaired, or when some parts need to be replaced, the user can easily withdraw and manage the mounting part (120).

[0224] An entrance (127) through which a robot cleaner (200) is introduced may be formed in the mounting portion (120). The entrance (127) may refer to a space formed on the front surface of the robot cleaner station (100).

[0225] The entrance (127) may be formed to a size that allows the robot cleaner (200) to pass through. That is, the height of the entrance (127) is formed to be greater than the height of the robot cleaner (200). At this time, the entrance (127) may refer to a space formed upward in a vertical direction from the front end of the base (121) described later, and the upper end of the entrance may be the same as the lower surface of the lower plate (23) of the kitchen cabinet (2) or the upper end of the housing (110).

[0226] In addition, the entrance (127) is formed so that the width in the left and right directions is larger than the maximum width of the robot cleaner (200). At this time, 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 form a boundary with the dust collection unit (140) and the mop washing unit (160). If there is no dust collection unit (140) or mop washing unit (160), the outer wall surface of the housing (110) may also form a boundary.

[0227] At this time, the entrance (127) can be opened and closed by the door (126). The door (126) can be positioned at the top or bottom of the entrance (127) and can be provided with a rotation axis that is parallel to the base (121). The door (126) can be hinged to the housing (110). Alternatively, the door (126) can be hinged to the inner wall (124) of the mounting portion (120).

[0228] The door (126) can be rotated by a door driving unit (126a). For example, the door driving unit (126a) can be a motor.

[0229] For example, the door (126) may be formed in a rectangular flat plate shape, may be provided with a hinge portion (126b) at the top, and a door driving portion (126a) may be connected to one axial end of the hinge portion (126b). At this time, the hinge portion (126b) of the door (126) may be directly connected to the shaft of the door driving portion (126a), or may be connected so as to transmit power through at least one gear.

[0230] The door (126) can keep the entrance (127) closed when the robot cleaner (200) is accommodated in the mounting portion (120). In addition, when the robot cleaner (200) starts to move from the mounting portion (120), the door (126) can be rotated to open the entrance (127). In addition, the door (126) can be rotated to close the entrance (127) after the robot cleaner (200) passes through the entrance (127). In addition, the door (126) can be rotated to open the entrance (127) when the robot cleaner (200) approaches from the outside of the cleaner station (100).

[0231]

[0232] The mounting portion (120) may include a receiving space (S), a base (121), a joining wall (123), and an inner wall (124).

[0233] A robot cleaner (200) can be accommodated in the accommodation space (S) of the mounting portion (120). For example, the accommodation space (S) may refer to a space surrounded by a base (121), a joining wall (123), and an inner wall (124). As another example, the accommodation space (S) may refer to a space surrounded by a base (121), a washing plate (122), a joining wall (123), and an inner wall (124). As another example, the accommodation space (S) may refer to a space where a robot cleaner (200) is located while the robot cleaner (200) is connected to a power supply terminal (123b), or a space where a robot cleaner (200) is located while the dust bin (220) of the robot cleaner (200) is connected to a dust passage hole (123a).

[0234]

[0235] The base (121) can be positioned so that the robot cleaner station (100) is in contact with the floor surface, and is configured to support the robot cleaner (200) when the robot cleaner (200) is coupled to the robot cleaner station (100).

[0236] The base (121) may include a base bottom surface (121a), an inclined portion (121b), a wheel coupling portion (121c), an agitator receiving portion (121d), and a washing tank (128).

[0237] The base bottom surface (121a) can form the overall exterior of the base (121). An inclined portion (121b), a wheel coupling portion (121c), an agitator receiving portion (121d), and a washing tank (128) can be arranged on the base bottom surface (121a).

[0238] The base bottom surface (121a) may be formed in a form in which the width (or diameter) in the horizontal direction (parallel to X and Y) is greater than the height in the vertical direction (parallel to Z). This structure has the effect of stably supporting the robot cleaner station (100) on the floor surface.

[0239] A circulation path may be provided inside the base bottom surface (121a). Accordingly, air discharged from the dust collection motor (145) may flow through the circulation path formed inside the base bottom surface (121a) and be exhausted to the air return port (125b).

[0240] The slope (121b) can be placed at the entrance through which the robot cleaner (200) climbs on the base floor surface (121a).

[0241] The inclined portion (121b) may have an upward slope toward the front in the direction in which the robot cleaner (200) enters. More specifically, the inclined portion (121b) may be connected so that the front end of the entrance side has no height difference with the ground, but may have an upward slope toward the front in the direction in which the robot cleaner (200) enters. In this case, the forward end in the direction in which the robot cleaner (200) enters means the rear with respect to the robot cleaner station (100). As a result, the robot cleaner (200) can easily climb up from the ground to the robot cleaner station (100).

[0242] A wheel guide portion (121ba) may be provided on the slope portion (121b).

[0243] The wheel guide part (121ba) may be formed in the form of a groove to guide the movement of the wheel (260) of the robot cleaner (200). The surface of the wheel guide part (121ba) may be formed to correspond to the surface of the wheel (260) so that the robot cleaner (200) can travel stably. In addition, the wheel guide part (121ba) may be formed so that the width of the groove at the entrance through which the robot cleaner (200) climbs is larger than the width of the wheel (260), and the width of the groove compared to the entrance becomes narrower as it goes forward in the climbing path of the robot cleaner (200). As a result, the wheel (260) of the robot cleaner (200) can easily enter the robot cleaner station (100), but the left and right movement is restricted by the groove that becomes narrower, so that the wheel (260) can be guided to the correct position.

[0244] An auxiliary wheel guide part (121bb) may be provided on the slope part (121b).

[0245] The auxiliary wheel guide part (121bb) may be formed in a groove shape to guide the movement of the auxiliary wheel (270) of the robot cleaner (200). In addition, the auxiliary wheel guide part (121bb) may be formed in a protruding shape so as to come into contact with the auxiliary wheel (270) when the wheel (260) of the robot cleaner (200) is seated on the wheel guide part (121ba). Accordingly, when the robot cleaner (200) drives on an inclined part (121b), it can drive while being stably supported by not only the wheel (260) but also the auxiliary wheel (270).

[0246] The wheel (260) of the robot cleaner (200) that has moved upward along the wheel guide (121ba) can be seated on the wheel coupling portion (121c). When the wheel (260) of the robot cleaner (200) is seated on the wheel coupling portion (121c), the physical connection between the robot cleaner (200) and the robot cleaner station (100) can be formed. The surface of the wheel coupling portion (121c) can be formed to correspond to the surface of the wheel (260) so that the robot cleaner (200) can be stably stopped. The wheel coupling portion (121c) can extend from the upper end of the wheel guide portion (121ba). The wheel coupling portion (121c) can be connected to the wheel guide portion (121ba) without a step. As a result, the robot cleaner (200) can easily move past the inclined portion (121b) to the wheel coupling portion (121c).

[0247] The wheel coupling portion (121c) can be positioned at the stop position of the left and right wheels (260) of the robot cleaner (200) so that the robot cleaner (200) stops at the designated position. Here, the stop position of the wheel (260) means a position at which the robot cleaner (200) stops in order to be connected to the power supply terminal (123b) and / or a position at which the dust bin (220) of the robot cleaner (200) stops in order to be connected to the dust passage hole (123a).

[0248] The shape of the wheel coupling portion (121c) may be formed in a shape corresponding to the shape of the wheel (260) of the robot cleaner (200), i.e., in an arch shape. Through this configuration, the robot cleaner (200) can move along the wheel guide portion (121ba) and stop at the same time as the wheel (260) is inserted into the wheel coupling portion (121c), and the wheel (260) can be stably seated in the arch-shaped wheel coupling portion (121c).

[0249] The agitator receiving portion (121d) can receive at least a portion of the agitator (250) of the robot cleaner (200). Specifically, the agitator receiving portion (121d) can provide a space in which the lower portion of the agitator (250) of the robot cleaner (200) is received while the wheel (260) of the robot cleaner (200) is seated on the wheel coupling portion (121c).

[0250] 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 cleaner (200). The agitator receiving portion (121d) may be formed in a rectangular parallelepiped shape with an open upper portion. The lower surface of the agitator receiving portion (121d) may be sealed by the bottom surface of the base bottom surface (121a) or the bottom surface of the housing (110). Accordingly, the agitator (250) of the robot cleaner (200) that has moved upward along the inclined portion (121b) may be settled into the recessed portion (121da) through the open upper surface of the agitator receiving portion (121d). At this time, the depth of the recessed portion (121da) may be formed shallower than the depth of the wheel coupling portion (121c).

[0251] The agitator receiving portion (121d) may include a recessed portion (121da) and a protruding portion (121db).

[0252] The recessed portion (121da) may be formed to be recessed in the base (121). The recessed portion (121da) may form a receiving space in which at least a portion of the agitator (250) is received. Through this, when the wheel (260) of the robot cleaner (200) is seated on the wheel coupling portion (121c), at least a portion of the agitator (250) may be received in the receiving space of the recessed portion (121da).

[0253] The accommodation space of the recessed portion (121da) can be communicated with the accommodation space (S) of the settling portion (120).

[0254] The protrusion (121db) may be formed to protrude from the base (121). The protrusion (121db) may be arranged along the edge of the recessed portion (121da). In addition, when the agitator (250) is accommodated in the accommodation space of the recessed portion (121da), the protrusion (121db) may be arranged to be spaced a predetermined distance from the body (210) of the robot cleaner (200).

[0255] The protrusion (121db) can guide the air discharged through the air return port (125b) to the suction part (211) of the robot cleaner (200). Through this, the air discharged into the receiving space of the recessed part (121da) can be guided to the suction part (211) of the robot cleaner (200) by the protrusion (121db).

[0256] An air circulating port (125b) may be formed in the agitator receiving portion (121d). The air circulating port (125b) may be formed on a side of the agitator receiving portion (121d). The air circulating port (125b) may connect the recessed portion (121da) and the dust collecting motor (145) through a circulation path. The recessed portion (121da) and the circulation path may be communicated through the air circulating port (125b). Therefore, air discharged from the dust collecting motor (145) may pass through the air circulating port (125b) and be discharged to the recessed portion (121da) of the agitator receiving portion (121d).

[0257]

[0258] The joining wall (123) is configured to place the dust passage hole (123a), power supply terminal (123b), and water supply nozzle (123c) of the robot cleaner station (100). The joining wall (123) can spatially separate the receiving space (S) from the components of the robot cleaner station (100). The joining wall (123) can extend vertically from the rear side of the base (121). The joining wall (123) can be formed to correspond to the shape of the robot cleaner (200). For example, when the body (210) of the robot cleaner (200) has a cylindrical shape, the joining wall (123) can be formed in an arc shape with a predetermined radius. With such a configuration, the outer surface of the robot cleaner (200) can be surrounded, and the area facing the outer surface of the robot cleaner (200) can be increased. Additionally, it can stably support the robot vacuum cleaner (200).

[0259]

[0260] A dust passage hole (123a) may be formed in the mounting portion (120) to allow air from outside the housing (110) to flow into the inside. Specifically, a dust passage hole (123a) may be formed in the joining wall (123) to allow air from outside the housing (110) to flow into the inside. The dust passage hole (123a) may be communicated with a dust bin (220) of a robot cleaner (200). The dust passage hole (123a) may be communicated with a dust outlet (221) of the dust bin (220) of the robot cleaner (200). The dust passage hole (123a) may be formed in a hole shape corresponding to the shape of the dust bin (220) so that dust in the dust bin (220) may flow into the dust collection unit (140). The dust passage hole (123a) may be formed corresponding to the shape of the dust outlet (221) of the dust bin (220). The dust passage hole (123a) can be formed to communicate with the dust collection path (130). Air sucked into the dust passage hole (123a) can flow through the dust collection path (130) and then be exhausted through the air return unit (125).

[0261]

[0262] The robot cleaner station (100) may include a power supply module that supplies power to the robot 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. In addition, the power supply terminal (123b) may be positioned forward of the power supply module housing and exposed on the coupling wall (123).

[0263] The power supply terminal (123b) can supply power to the robot 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 cleaner (200). The power supply terminal (123b) can be arranged on the mounting portion (120). Specifically, the power supply terminal (123b) can be arranged on the coupling wall (123). The power supply terminal (123b) can be electrically connected to the robot cleaner (200) coupled to the coupling wall (123). The power supply terminal (123b) can supply power to the battery of the robot cleaner (200) coupled to the coupling wall (123).

[0264]

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

[0266] The water supply nozzle (123c) can be connected to the supply part (231) of the water tank (230) of the robot cleaner (200). Specifically, the water supply nozzle (123c) can be connected to the inlet of the water tank (230). The inlet is configured to be connected to the water tank (230) of the robot cleaner (200). 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 cleaner (200).

[0267]

[0268] The inner wall (124) is a configuration that spatially divides the receiving space (S) of the mounting portion (120) from the components of the robot 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 in a direction intersecting the base (121) from the left and right sides of the base (121). Specifically, the inner walls (124) may extend in a vertical direction from the left and right sides of the base (121). The height of the inner walls (124) may be formed to correspond to the height of the pedestal (21). Specifically, the height of the inner walls (124) may be formed to be the same as the height of the pedestal (21).

[0269] Meanwhile, various components such as a dust collection path (130), a dust collection unit (140), a dust collection motor (145), a detergent container (163), and a waste container (164) can be arranged on the outside of the inner wall (124). Specifically, a dust collection unit (140), a detergent container (163), and a waste container (164) can be accommodated in the space between the inner wall (124) and the outer wall (111) of the housing (110).

[0270] The dust collection unit (140) and the detergent container (163) can be separated in a sliding manner from the space between the inner wall (124) and the outer wall (111) of the housing (110). The width in the left and right direction of the dust collection unit (140) and the detergent container (163) can be formed to correspond to the distance between the inner wall (124) and the outer wall (111) of the housing (110).

[0271]

[0272] The washing plate (122) is configured to wash the mop of the robot cleaner (200), and the washing plate (122) can be installed in the washing tank (128) of the base (121). In addition, the washing plate (122) can come into contact with the mop (242) while the robot cleaner (200) is installed.

[0273] The washing plate (122) may be a plate formed to slope downwards toward the center.

[0274] Specifically, the washing plate (122) includes a washing plate inclined surface (122c) formed in a curved shape. Furthermore, at least one main passage hole (122b) through which a fluid can pass may be formed on the washing plate inclined surface (122c). Furthermore, a washing protrusion (122a) may be formed to protrude on the washing plate inclined surface (122c).

[0275] At this time, a pair of cleaning protrusions (122a) may be symmetrically formed on the cleaning plate slope (122c). Specifically, a pair of cleaning protrusions (122a) may be arranged vertically below a pair of mops (242) of the robot cleaner (200), so as to face the pair of mops (242), and may be arranged so as to be in contact with at least a portion of the pair of mops (242).

[0276] In addition, a plurality of main passage holes (122b) may be formed on the washing plate slope (122c), and may be formed between a pair of washing protrusions (122a). For example, a plurality of main passage holes (122b) may be formed at a location on the washing plate slope (122c) that has the lowest height from the ground (kitchen floor), and may be formed between a pair of washing protrusions (122a). Through this, the fluid discharged between the pair of washing protrusions (122a) may be guided to flow into the main passage holes (122b).

[0277] Meanwhile, the height of the washing plate slope (122c) from the kitchen floor may increase as it moves toward the rear from the position where the main passage hole (122b) is formed. In other words, the height of the washing plate slope (122c) from the kitchen floor may increase as it approaches the outside air discharge unit (171c) described later.

[0278] With this configuration, the wash water and / or air can be guided by the wash plate slope (122c) to flow through the main passage hole (122b) and into the space formed between the wash plate (122) and the wash tank (128). Through this, the heated air can pass through the main passage hole (122b) and be supplied to the wash tank (128).

[0279] Accordingly, when the driving unit of the rotating cleaning unit (240) is driven while the mop (242) of the robot cleaner (200) is placed on the washing plate (122), the mop (242) rotates. At this time, when the mop (242) rotates while washing water is supplied to the washing plate, the mop (242) can be washed by rubbing against the washing projection (122a) that is in a stationary state.

[0280]

[0281] The washing tank (128) is configured to accommodate the washing plate (122). The washing tank (128) may be positioned on the rear side of the base bottom surface (121a). The washing tank (128) is positioned on 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 inserted therein. Liquid that has passed through the washing plate (122) may flow into the washing tank (128).

[0282] The washing tank (128) may include a washing tank base surface through which the fluid passing through the washing plate (122) flows and a base wall formed to protrude vertically from the outer surface of the washing tank base surface. At this time, the height of the washing tank base surface from the ground (kitchen floor) may decrease as it goes toward the rear of the robot cleaner station (100). Through this, the 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) described later.

[0284] dust collection unit

[0285]

[0286] FIG. 12 and FIG. 13 are side views illustrating a dust collection unit of a robot cleaner station according to an embodiment of the present invention, and FIG. 14 is a cross-sectional view illustrating a dust collection path of a robot cleaner station according to an embodiment of the present invention.

[0287] Referring to FIGS. 12 to 14 and FIG. 17, the dust collection unit (140) is described as follows.

[0288] The dust collection unit (140) can collect dust from the dust bin (220) of the robot cleaner (200). The dust collection unit (140) can be placed inside the housing (110). The dust collection unit (140) can be placed outside the mounting unit (120). At this time, the receiving space (S) can be placed inside the mounting unit (120).

[0289] The dust collection unit (140) may include a dust collection unit housing (141), a dust bag (not shown), a filter (142), and a dust bag drawer (144).

[0290] The dust collection unit housing (141) can form a space inside which a dust bag (not shown), a filter (142), and a dust bag drawer (144) can be accommodated.

[0291] The dust collection housing (141) is connected to a dust bag drawer (144) so ​​that a dust bag can be withdrawn therein, and a dust bag (not shown) can be stored inside the dust bag drawer (144). For example, the dust collection housing (141) is formed in a rectangular tube shape 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).

[0292] One side of the inside of the dust collection unit housing (141) can be communicated with the first dust collection path (147), and the other side can be communicated with the second dust collection path (148). In addition, when a dust bag (not shown) is combined with the dust collection unit housing (141), the dust bag (not shown) can be communicated with the first dust collection path (147) inside the dust collection unit housing (141).

[0293] A dust bag (not shown) may refer to a dust bag that collects dust sucked from inside a dust bin (220) of a robot cleaner (200) by a dust collecting motor (145). The dust bag (not shown) may be detachably coupled to a dust collecting unit housing (141). Accordingly, the dust bag (not shown) may be separated from the dust collecting unit housing (141) and discarded, and a new dust bag (not shown) may be coupled to the dust collecting unit housing (141). In other words, the dust bag (not shown) may be defined as a consumable part.

[0294] The dust bag (not shown) may be provided so that when suction power is generated by the dust collection motor (145), its volume increases and dust is accommodated inside.

[0295] To this end, the dust bag (not shown) may be made of a material that is permeable to air but impermeable to foreign substances such as dust. For example, the dust bag (not shown) may be made of a non-woven material, and may have a hexahedral shape corresponding to the shape of the dust collection unit housing (141) when its volume increases.

[0296] A filter (142) may be placed between the dust collection unit housing (141) and the second dust collection path (148). The filter (142) may be placed at the outlet (141b). The filter (142) may be a pre-filter or a HEPA filter. Air passing through the dust bag (not shown) may flow into the second dust collection path (148) through the filter (142).

[0297] The dust bag drawer (144) is connected so as to be withdrawable from the dust collection unit housing (141), and a dust bag (not shown) can be accommodated inside.

[0298] At this time, referring to FIG. 17, the dust bag drawer (144) includes a dust bag drawer body (144a), a handle (144d), and a drawer rail (144e).

[0299] The dust bag drawer body (144a) may provide a space where a dust bag (not shown) can be combined inside. For example, the dust bag drawer body (144a) may be formed in a box shape with an open top, and an inlet (144b) and an outlet (144c) may be formed at the rear so as to be able to communicate with the first dust collection path (147) and the second dust collection path (148).

[0300] For example, the dust bag drawer body (144a) may be formed so that the upper left-right width and the lower left-right width are different. For example, the upper left-right width of the dust bag drawer body (144a) may be formed so that it is larger than the lower left-right width. That is, the interior of the dust bag drawer body (144a) may be formed in a step. Through this, the upper space where the dust bag (not shown) is provided can be maximized, and a path can be formed so that the air passing through the dust bag (not shown) can easily escape to the lower side.

[0301] The upper side of the dust bag drawer body (144a) can be connected to the first dust collection path (147) through the inlet (144b). The inlet (144b) may be configured to guide air flowing through the first dust collection path (147) into the interior of the dust bag (not shown). The inlet (144b) can connect the first dust collection path (147) and the dust bag (not shown). Therefore, dust sucked from the dust bin (220) of the robot cleaner (200) can move into the interior of the dust bag (not shown) through the first dust collection path (147) and the inlet (144b).

[0302] The dust bag drawer (144) can be connected to the second dust collection path (148) through an outlet (144c) formed on the lower side. The outlet (144c) may be configured to guide air passing through the dust bag drawer (144) to the second dust collection path (148). The outlet (144c) may be arranged at a different height from the inlet (144b). The outlet (144c) may be arranged lower than the inlet (144b). The outlet (144c) may connect the internal space of the dust bag drawer (144) and the second dust collection path (148). Therefore, air from which dust is filtered while passing through the dust bag (not shown) can move to the second dust collection path (148) through the outlet (144c).

[0303] A handle (144d) may be provided at the front of the dust bag drawer body (144a). The handle (144d) may be provided so that a user can grip it. For example, the handle (144d) may include a pair of connecting portions hingedly connected to the front surface of the dust bag drawer body (144a), and a grip portion formed by connecting the pair of connecting portions so that a user can grip it.

[0304] With this configuration, when a user holds the handle and pulls it forward, the dust bag drawer body (144a) can be pulled forward and withdrawn as well. Therefore, according to the present invention, a user can easily pull the dust bag drawer (144) forward, and then lift the dust bag (not shown) upward to remove and replace it.

[0305] A drawer rail (144e) may be formed on the left and right sides of the dust bag drawer body (144a). The drawer rail (144e) may guide the movement of the dust bag drawer body (144a).

[0306] For example, the drawer rail (144e) may be formed in the form of a groove or rib along the front-back direction on the left and right sides of the dust bag drawer body (144a).

[0307] With this configuration, when the user attaches the dust bag drawer (144) to the dust collection unit housing (141), it can be attached in the correct position, and the dust collection unit (140) and the first dust collection path (147) and the second dust collection path (148) can be connected in the correct position to reduce flow loss.

[0308] Meanwhile, a rail (141a) may also be formed on the inner surface of the dust collector housing (141) corresponding to the drawer rail (144e). The rail (141a) of the dust collector housing (141) may be formed corresponding to the shape and position of the drawer rail (144e). For example, if the drawer rail (144e) is formed in a groove shape, the rail (141a) of the dust collector housing (141) may be formed in a rib or protruding ledge shape.

[0309] Meanwhile, the robot cleaner station (100) may include a dust collection path. The dust collection path may refer to a path through which air sucked in through the dust passage hole (123a) flows through the dust bag to the dust collection motor (145).

[0310] Specifically, when the robot cleaner (200) is coupled to the robot cleaner station (100) and the dust passage hole (123a) and the dust bin (220) of the robot cleaner (200) are connected, 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), and a second dust collection path (148) that connects the internal space of the dust collection unit housing (141) and the dust collection motor (145).

[0311] The first dust collection path (147) can connect the dust bin (220) of the robot cleaner (200) and the internal space of the dust collection unit housing (141). The first dust collection path (147) can communicate the dust bin (220) of the robot cleaner (200) and the internal space of the dust collection unit housing (141). The first dust collection path (147) can connect the dust passage hole (123a) of the mounting part (120) and the internal space of the dust collection unit housing (141). The first dust collection path (147) can mean the space between the dust bin (220) of the robot cleaner (200) and the dust collection unit housing (141). The first dust collection path (147) can be formed close to the horizontal direction. The first dust collection path (147) may be a space formed toward the rear of the dust passage hole (123a), or may be a path formed by bending toward the side of the dust passage hole (123a) so that dust and air can flow. Through the first dust collection path (147), dust inside the dust bin (220) of the robot cleaner (200) can move to the internal space of the dust collection unit housing (141).

[0312] The second dust collection path (148) can connect the internal space of the dust collection unit housing (141) and the dust collection motor (145). The second dust collection path (148) can be formed in a nearly horizontal direction. At this time, the first dust collection path (147) and the second dust collection path (148) can be formed at different heights. The first dust collection path (147) and the second dust collection path (148) can be formed in a layered structure. The second dust collection path (148) can be arranged lower than the first dust collection path (147). With this configuration, the left-right width and the overall volume of the robot cleaner station (100) can be minimized.

[0313] The dust collection module can provide suction airflow to the dust collection path.

[0314] Specifically, the dust collection module may include a dust collection motor housing (146) and a dust collection motor (145).

[0315] The dust collecting motor housing (146) can be placed inside the housing (110). The dust collecting motor housing (146) can accommodate the dust collecting motor (145) inside.

[0316] The internal space of the dust collecting motor housing (146) can be communicated with the second dust collecting passage (148). Therefore, air flowing through the second dust collecting passage (148) can be guided to the dust collecting motor (145).

[0317] The internal space of the dust collecting motor housing (146) can be communicated with the circulation path. Therefore, air passing through the dust collecting motor (145) can be guided to the circulation path.

[0318] The dust collection motor (145) can generate suction force in the dust collection path.

[0319] The dust collecting motor (145) can be placed at the rear of the dust collecting unit housing (141). Through this, the dust collecting motor (145) can provide suction power capable of sucking up dust inside the dust bin (220) of the robot cleaner (200).

[0320] The dust collecting motor (145) can generate suction force by rotation. For example, the dust collecting motor (145) can be formed in a shape similar to a cylinder.

[0321] The dust collecting motor (145) may have one side connected to the second dust collecting passage (148) and the other side connected to the circulation passage. When the dust collecting motor (145) is driven, air flowing through the second dust collecting passage (148) may be introduced into the dust collecting motor housing (146). In addition, the air introduced into the dust collecting motor housing (146) may flow through the circulation passage after passing through the dust collecting motor (145) and be exhausted through the air return port (125b).

[0322] Meanwhile, the rotation axis of the dust collection motor (145) can be formed close to the horizontal direction. With this configuration, the overall volume of the robot cleaner station (100) placed in the kitchen cabinet (2) or the installation space (21a) of the structure can be minimized.

[0323] Meanwhile, according to an embodiment, the rotation axis of the dust collecting motor (145) may be arranged along the vertical direction. In this case, the horizontal space occupied by the dust collecting motor (145) can be minimized.

[0324] The air circulation unit (125) can guide the air discharged from the dust collection motor (145) to the robot cleaner (200).

[0325] The air circulating section (125) may be composed of a circulation path and an air circulating port (125b).

[0326] The circulation path can provide a path through which air discharged from the dust collector motor (145) flows. The circulation path can be arranged inside the base bottom surface (121a).

[0327] The circulation path may be connected to the dust collecting motor (145) in a flow direction. The circulation path may refer to a flow path connecting the internal space of the motor housing (151) and the air return port (125b). One end of the circulation path may be connected to the internal space of the dust collecting motor housing (146), and the other end of the circulation path may be connected to the receiving space of the recessed portion (121da).

[0328] The circulation path may be a path formed horizontally within the housing (110). The circulation path may be connected to the dust collecting motor (145) in a flow direction. Specifically, one end of the circulation path may be connected to the internal space of the dust collecting motor housing (146), and the other end of the circulation path may be connected to the air return port (125b).

[0329] The air return port (125b) can serve as an outlet that guides air discharged from the dust collection motor (145) to the receiving space of the recessed portion (121da).

[0330] The air reflux port (125b) may be formed in the base (121). The air reflux port (125b) may be formed in the agitator receiving portion (121d). The air reflux port (125b) may be formed in the side wall of the recessed portion (121da).

[0331]

[0332] The circulation path according to the embodiment of the present invention can guide the air discharged from the dust collecting motor (145) to the suction part (211) of the robot cleaner (200).

[0333] The circulation path can create a structure in which the air discharged from the dust collecting motor (145) is guided to the suction part (211) of the robot cleaner (200) instead of being discharged to the outside, so that the air continuously circulates between the robot cleaner (200) and the robot cleaner station (100). As a result, the heat discharged from the dust collecting motor (145) is not discharged to the kitchen cabinet (2), but is re-introduced into the interior of the robot cleaner (200) and circulated, thereby preventing the interior of the kitchen cabinet (2) from being damaged.

[0334] The air passing through the dust collecting motor (145) is discharged to the receiving space (S) through the air return port (125b), and the air discharged to the receiving space (S) can be re-introduced into the suction unit (211) due to the suction force of the dust collecting motor (145). Therefore, the air sucked in from the dust bin (220) by the suction force of the dust collecting motor (145) can flow sequentially through the dust passage hole (123a), the first dust collecting passage (147), the dust collecting unit housing (141), the second dust collecting passage (148), the dust collecting motor (145), the circulation passage, and the air return port (125b), and then be discharged to the receiving space (S).

[0335] At this time, the dust collection motor (145) can be driven together with the suction motor (not shown) of the robot cleaner (200). The air exhausted through the air return port (125b) is sucked into the suction unit (211) by the suction power of the suction motor (not shown) in addition to the dust collection motor (145), thereby improving the dust collection efficiency.

[0338]

[0339] FIG. 15 is an enlarged view illustrating a mop washing unit of a robot cleaner station according to an embodiment of the present invention, FIG. 16 is an enlarged view illustrating a washing water supply unit of a mop washing unit of a robot cleaner station according to an embodiment of the present invention, and FIG. 17 is a drawing illustrating a state in which a dust collection unit and a detergent container are withdrawn from a robot cleaner station according to an embodiment of the present invention.

[0340] Referring to FIGS. 15 to 17, the mop washing unit (160) of the robot cleaner station (100) according to an embodiment of the present invention will be described as follows.

[0341] A robot cleaner station (100) according to an embodiment of the present invention may include a mop washing unit (160). The mop washing unit (160) may wash a mop (242) of a robot cleaner (200) coupled to a mounting unit (120).

[0342] The mop washing unit (160) may include a washing water supply unit (161) that discharges washing water to the washing plate (122), a detergent container (163) that stores liquid including detergent, and a waste water container (164) that stores washing water after washing the mop (242).

[0343] In the washing water supply unit (161), purified water and detergent can be mixed to produce washing water for washing the mop (242).

[0344]

[0345] *The washing water supply unit (161) includes a branch flow path (161a), a purified water inlet (161b), a detergent inlet (161c), a detergent pump (161d), and a washing water discharge port (161e).

[0346] At this time, a pair of washing water discharge ports (161e) may be spaced apart from each other on the rear side of the joining wall (123). The washing water discharge ports (161e) may discharge washing water toward the washing plate (122) from the upper side of the washing plate (122). For example, a pair of washing water discharge ports (161e) may be arranged on the upper side of a pair of washing protrusions (122a).

[0347] At this time, purified water supplied from the water supply pipe of the kitchen cabinet (2) and passed through the regulator (162) can be branched to both sides through a branch flow path (161a) and connected to each of the wash water outlets (161e) that are spaced apart from each other. That is, the branch flow path (161a) can be formed in the form of one pipe branching into two, and at this time, one of the branched ends can be connected to one of the pair of wash water outlets (161e), and the other of the branched ends can be connected to the other of the pair of wash water outlets (161e). Accordingly, the branch flow path (161a) can supply wash water to the pair of wash water outlets (161e).

[0348] The washing water discharge port (161e) may be formed integrally with the joining wall (123) on the rear side of the joining wall (123), or may be detachably joined to the joining wall (123).

[0349] The purified water inlet (161b) is configured to guide purified water supplied from the water supply pipe of the kitchen cabinet (2) to the washing water supply unit (161). Specifically, the water supply pipe of the kitchen cabinet (2) is connected to a regulator (162), so that the flow rate supplied from the water supply pipe can be adjusted. In addition, a portion of the purified water that has passed through the regulator (162) can be supplied to the water tank (230) of the robot cleaner (200) through the water supply nozzle (123c), and the remainder can be introduced into a pair of washing water supply units (161) that are spaced apart from each other through the purified water inlet (161b).

[0350] The detergent inlet (161c) is configured to guide liquid containing detergent supplied from the detergent container (163) to the washing water supply unit (161). Specifically, the liquid containing detergent stored in the detergent container (163) can be supplied to the washing water supply unit (161) via the detergent pump (161d).

[0351] In addition, detergent and purified water introduced into the washing water supply unit (161) can be mixed and used as washing water. The washing water supply unit (161) can discharge washing water to the upper surface of the washing plate (122) through the washing water discharge port (161e). The washing water discharge port (161e) can be opened in a direction facing the upper surface of the mop (242) mounted on the washing plate (122).

[0352] The detergent container (163) can store liquids including detergent.

[0353] The detergent container (163) includes a detergent container body (163a), a handle (163b), and a detergent container rail (163c) (see drawing).

[0354] The detergent container body (163a) may provide a space for storing liquid, including detergent. For example, the detergent container body (163a) may be formed in a box shape with an open top, and the rear may be connected to a washing water supply unit (161).

[0355] A handle (163b) may be provided at 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 include a pair of connecting portions hingedly connected to the front surface of the detergent container body (163a), and a grip portion formed by connecting the pair of connecting portions so that a user can grip it.

[0356] With this configuration, when a user holds the handle and pulls it forward, the detergent container body (163a) can be pulled forward and withdrawn. Therefore, according to the present invention, a user can easily pull the detergent container (163) forward and then supply detergent.

[0357] A detergent container rail (163c) may be formed on the left and right sides of the detergent container body (163a). The detergent container rail (163c) may guide the movement of the detergent container body (163a).

[0358] For example, the detergent container rail (163c) may be formed in the form of a groove or rib along the front-back direction on the left and right sides of the detergent container body (163a).

[0359] With this configuration, when the user attaches the detergent container (163) to the housing (110), it can be attached in the correct position and the washing water can be prevented from leaking out.

[0360] Meanwhile, although not shown, a rail may be formed in the housing (110) corresponding to the detergent container rail (163c). The above rail may be formed corresponding to the shape and position of the detergent container rail (163c).

[0361] The wastewater tank (164) can provide a space for storing the washing water used to wash the mop (242). The washing water discharged to the upper surface of the washing plate (122) can be drained into the main passage hole (122b) while descending along the slope of the washing plate (122) after washing the mop (242). The washing water passing through the main passage hole (122b) accumulates in the washing tank (128). In addition, the washing water accumulated in the washing tank (128) can flow into the wastewater suction path (164b) through the wastewater inlet (164c) and can flow into the wastewater tank (164) through the wastewater inlet path (164b). That is, the liquid passing through the washing plate (122) can flow along the washing tank (128) and be discharged through the wastewater inlet (164c).

[0362] Meanwhile, a sewage suction passage (164b) is formed in a sewage suction pipe, and a sewage inlet (164c) is formed at one end of the sewage suction pipe, and the other end of the sewage suction pipe is connected to a sewage tank (164). At this time, the sewage suction pipe may be arranged to pass through the lower side of the outside air supply module (171). That is, the sewage suction passage (164b) may be arranged at the lower side of the outside air supply module (171). In addition, the sewage suction passage (164b) may be arranged at the lower side of the outside air supply passage (171a).

[0363] Washing water stored in the wastewater tank (164) can be drained to the drain pipe (25) of the kitchen cabinet (2) through the wastewater discharge path (164a). One end of the wastewater discharge path (164a) can be connected to the wastewater tank (164), and the other end can be connected to the drain pipe (25). At this time, the washing water stored in the wastewater tank (164) can be drained to the drain pipe by flowing through the wastewater discharge path (164a) by a centrifugal pump (not shown).

[0364] The sewage discharge path (164a) connected to the sewage tank (164) can be connected upstream (25b) based on the drain trap (25a) of the drain pipe (25) of the kitchen cabinet (2). This is because, if the sewage discharge path (164a) is connected downstream (25c) based on the drain trap (25a) of the drain pipe (25), foul odors or fluids inside the drain pipe (25) may flow back into the sewage discharge path (164a).

[0365] Additionally, the mop washing unit (160) may include a check valve (not shown). The check valve may prevent the fluid inside the drain pipe (25) from flowing back into the sewage discharge path (164a). The check valve may be provided at the other end of the sewage discharge path (164a) connected to the drain pipe (25).

[0366] Meanwhile, the detergent container (163) and the waste container (164) can be accommodated in the space formed between the inner wall (124) and the outer wall (111) of the housing. The detergent container (163) can be placed on the lower side of the space between the inner wall (124) and the outer wall (111) of the housing, and the waste container (164) can be placed on the upper side of the detergent container (163) in the space between the inner wall (124) and the outer wall (111) of the housing.

[0368] Mop drying section

[0369]

[0370] FIG. 18 is a perspective view illustrating a mop drying unit of a robot cleaner station according to an embodiment of the present invention, FIG. 19 is an enlarged view illustrating a mop drying unit of a robot cleaner station according to an embodiment of the present invention, and FIG. 20 is a cross-sectional view illustrating how air flows into a heat supply module according to an embodiment of the present invention.

[0371] Referring to FIGS. 18 to 20, a robot 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) may dry a mop (242) of a robot cleaner (200) that has been washed by a mop washing unit (160) or a mop (242) that is wet after a water cleaning task is completed.

[0372] A mop drying unit (170) according to one embodiment of the present invention may include an external air supply module (171), an air discharge unit (172), an exhaust fan (173), and a check valve (175).

[0373] The outside air supply module (171) can supply heat to the receiving space (S) and can include an outside air supply path (171a), an outside air inlet (171b), an outside air discharge portion (171c), a heater (171d), and a blower fan (171e).

[0374] An external air advanced path (171a) is formed in the external air supply module (171). The external air supply path (171a) can flow external air to the external air discharge unit (171c).

[0375] The external air supply path (171a) can connect the external space of the housing (110) and the receiving space (S). One side of the external air supply path (171a) can be connected to the external space through the external air inlet (171b), and the other side of the external air supply path (171a) can be connected to the receiving space (S) through the external air discharge portion (171c).

[0376] An external air inlet (171b) may be formed on the rear surface of the housing (110). A plurality of external air inlets (171b) may be formed on the rear surface of the housing (110). Air outside the housing (110) may be introduced into the external air supply path (171a) through the external air inlet (171b). Accordingly, air outside the housing (110) may be introduced into the interior of the housing (110).

[0377] At least a portion of the outside air discharge portion (171c) may be positioned above the washing plate (122). The outside air discharge portion (171c) may be opened in a direction facing the washing plate (122). A pair of outside air discharge portions (171c) may be provided in a state in which they are opened downward.

[0378] The outside air discharge unit (171c) can discharge air that has passed through the outside air supply passage (171a). The outside air discharge unit (171c) can discharge air heated by the heater (171d). For example, an outside air discharge port may be formed in the outside air discharge unit (171c).

[0379] With the mop (242) secured to the cleaning plate (122), the outside air discharge portion (171c) can be opened toward the upper side of the mop (242). Accordingly, the outside air discharge portion (171c) is positioned adjacent to the mop (242) and opens downward, so that air discharged from the outside air discharge portion (171c) can flow toward the mop (242).

[0380] The blower fan (171e) is placed on the outside air supply path (171a) and can blow air toward the receiving space (S). When the blower fan (171e) is driven, air drawn in through the outside air inlet (171b) can be heated by the heater (171d) and discharged to the receiving space (S) through the outside air discharge portion (171c).

[0381] The heater (171d) is placed on the outside air supply passage (171a) and can heat the air flowing through the outside air supply passage (171a). The heater (171d) can heat the air discharged through the outside air discharge portion (171c).

[0382] The heater (171d) may include a heater housing and a heating element. At this time, the heater housing may be placed on an external air supply path (171a), and a space may be provided therein in which the heating element can be accommodated. In addition, the heating element may heat air flowing into the heater housing. Accordingly, air heated by the heating element may be discharged into the accommodation space (S) through the external air discharge portion (171c) to dry the wet mop (242).

[0383] The air exhaust unit (172) can exhaust the hot and humid air inside the robot cleaner station (100) generated while drying the mop (242) to the drain pipe (25). Specifically, the air exhaust unit (172) can connect the receiving space (S) and the drain pipe (25) of the kitchen cabinet (2).

[0384]

[0385] An air discharge path may be formed in the air discharge portion (172). At this time, one end of the air discharge path may be connected to the receiving space (S), and the other end may be connected to the drain pipe (25). Specifically, one end of the air discharge path, which is an air intake port (172a), may be connected to the receiving space (S), and the other end, which is an air discharge port (172b), may be connected to the drain pipe (25).

[0386] Meanwhile, the air intake port (172a) may be positioned at various locations on the receiving space (S). For example, the air intake port (172a) may be positioned on the joining wall (123). As another example, the air intake port (172a) may be positioned on the inner wall (124). As yet another example, the air intake port (172a) may be positioned higher from the ground than the mop (242), but may be positioned forward of the outside air discharge unit (171c). Through this, air containing steam generated during the drying process of the mop (242) can be discharged.

[0387] The air exhaust unit (172) may be connected downstream (25c) with respect to the oil trap (25a) of the drain pipe (25) of the kitchen cabinet (2). This is because, when the air exhaust unit (172) is connected upstream (25b) with respect to the oil trap (25a) of the drain pipe (25), the heat exhausted through the air exhaust unit (172) may not pass through the drain pipe (25) due to water accumulated in the oil trap (25a).

[0388] Meanwhile, according to one embodiment of the present invention, an air exhaust path may be formed by branching one pipe into two inside the housing (110) and penetrating both sides of the housing (110). At this time, one of the branches may penetrate the left outer wall surface of the housing (110), and the other branch may penetrate the right outer wall surface of the housing (110). The air exhaust portion (172) penetrating the outer walls (111) on both sides of the housing (110) may be connected to a drain pipe (25). Therefore, air sucked in from the air exhaust portion (172) may flow through the air exhaust ports (172b) branched to both sides and be exhausted downstream (25c) based on the oil trap (25a) of the drain pipe (25).

[0389] The exhaust fan (173) can exhaust air drawn in through the air intake port (172a) to the exhaust pipe (25). The exhaust fan (173) can cause flow in the air drawn in through the air discharge port (172). The exhaust fan (173) can be placed on the air discharge path.

[0390] When the exhaust fan (173) is driven, air in the receiving space (S) can be drawn into the air intake port (172a). The air drawn into the air intake port (172a) can flow through the air discharge portion (172) and be exhausted to the drain pipe (25). Specifically, when the exhaust fan (173) is driven and the air flowing through the air discharge portion (172) can be exhausted downstream (25c) based on the oil trap (25a) of the drain pipe (25).

[0391] The mop drying unit (170) may include a check valve (175). The check valve (175) may be provided at the other end of the air discharge path connected to the drain pipe (25). Through this, the fluid inside the drain pipe (25) can be prevented from flowing back into the air discharge unit (172).

[0393] Layout

[0394]

[0395] FIG. 21 and FIG. 22 are drawings illustrating the arrangement relationship on a horizontal plane of a robot cleaner station according to an embodiment of the present invention.

[0396] The arrangement of the robot cleaner station (100) according to the embodiment of the present invention will be described with reference to FIG. 4, FIG. 21, and FIG. 22 as follows.

[0397] The robot cleaner station (100) according to an embodiment of the present invention is characterized in that it is installed in the lower space of a kitchen cabinet (2).

[0398] To this end, the robot cleaner station (100) according to the embodiment of the present invention is characterized in that it is arranged horizontally to fit the space formed between the lower plate (23) of the kitchen cabinet (2) and the floor of the kitchen.

[0399] Specifically, the robot cleaner station (100) according to the embodiment of the present invention may have a dust collection unit (140) and / or a mop washing unit (160) placed on the side of the entrance (127).

[0400] At this time, if both a dust collection unit (140) and a mop washing unit (160) are provided, the mounting unit (120) can be placed between the dust collection unit (140) and the mop washing unit (160).

[0401] For example, an entrance (127) and a door (126) may be arranged at the front of the robot cleaner station (100). In addition, a mounting part (120) to which a robot cleaner (200) is coupled may be arranged at the rear from the entrance (127). At this time, a dust collection part (140) may be arranged from the front end of the robot cleaner station (100) to the rear by a predetermined length. In addition, a mop washing part (160) may also be arranged from the front end of the robot cleaner station (100) to the rear by a predetermined length.

[0402] Therefore, when looking at the robot cleaner station (100) from the front outside of the robot cleaner station (100), the front end of the dust collection unit (140) and / or the front end of the mop washing unit (160) can be placed on the left and right of the entrance (127).

[0403] At this time, the dust bag (not shown) of the dust collection unit (140) may be provided so as to be withdrawable 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 withdrawable to the front of the housing.

[0404] That is, a handle (144d) may be provided at the front end of the dust collection unit (140) so that a user can hold the dust collection unit housing (141). In addition, a handle (163b) may be provided at the front end of the mop washing unit (160) so that the detergent container (163) can be pulled.

[0405] With this configuration, when a user wants to withdraw a dust bag (not shown) or detergent container (163), the withdrawal location can be immediately recognized, and the convenience of being able to withdraw the dust bag (not shown) or detergent container (163) with just a simple action of pulling the handle can be provided.

[0406] 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). In addition, 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 connection of a wire supplying power to the dust collection motor (145) may be facilitated. In addition, there is an effect of minimizing the total space occupied by the mounting portion (120), the dust collection housing (141), and the dust collection motor (145) within a limited space.

[0407] In addition, at least a flow path for washing water for washing the mop (242) and a pump providing the flow force of the washing water 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 for washing water to flow from the water supply pipe can be minimized. In addition, there is an effect of minimizing the total space occupied by the mounting portion (120), the mop detergent container (163), and the flow path for washing water within a limited space.

[0408]

[0409] Meanwhile, the robot cleaner station (100) may have a mop drying unit (170) positioned rearward of the mounting unit (120). At this time, the mop drying unit (170) may be positioned between the rear end of the mounting unit (120) and the rear end of the housing (110).

[0410] Accordingly, the robot cleaner station (100) according to the embodiment of the present invention may have a dust collection unit (140) and a mop washing unit (160) arranged on the left and right sides of the mounting unit (120), and a mop drying unit (170) arranged on the rear side.

[0411] That is, in the robot cleaner station (100) according to the embodiment of the present invention, the dust collection unit (140), the mop washing unit (160), and the mop drying unit (170) can all be placed within a predetermined distance range from the outer edge of the mounting unit (120).

[0412] Through this arrangement, there is an effect in which the mounting unit (120), dust collection unit (140), mop washing unit (160), and mop drying unit (170) can all be placed in the narrowest space on the horizontal plane.

[0413] This has the effect of minimizing the loss of the flow path by shortening the distance between the dust bin (220) and the dust collection unit (140) of the robot cleaner (200). In addition, it has the effect of limiting the range in which the washing water and the washed wastewater exist by minimizing the distance between the mop (242) and the mop washing unit (160) of the robot cleaner (200) and the distance between the mop (242) and the mop drying unit (170) of the robot cleaner (200).

[0414] In addition, by this arrangement, the robot cleaner station (100) of the present invention can place all components within a limited height.

[0415] Specifically, based on the state in which the robot cleaner (200) is coupled to the mounting portion (120), at least a portion of the dust collection portion (140) may be positioned lower than the top of the robot cleaner (200). In addition, at least a portion of the mop washing portion (160) may be positioned lower than the top of the robot cleaner (200). In addition, at least a portion of the mop drying portion (170) may be positioned lower than the top of the robot cleaner (200).

[0416] In addition, based on the state in which the robot cleaner (200) is coupled to the mounting portion (120), the top of the robot cleaner (200) may be positioned higher than the dust bag drawer (144). In addition, the top of the robot cleaner (200) may be positioned higher than the detergent container (163). In addition, the top of the dust bag drawer (144) may be positioned higher than the detergent container (163).

[0417] As a result, the robot cleaner station (100) according to the embodiment of the present invention can have a dust collection unit (140), a mop washing unit (160), and a mop drying unit (170) arranged on three sides surrounding the mounting portion (120) except for the front side where the robot cleaner (200) enters. By this arrangement, even in a situation where the vertical height is limited, it is possible to charge the robot cleaner (200) using a minimum of horizontal space, as well as collect dust from the robot cleaner (200), wash the mop (242), and dry the mop (242).

[0418]

[0419] Drawer

[0420]

[0421] When the charging base for a robot vacuum cleaner is placed under a kitchen cabinet, it minimizes external exposure, thereby providing an interior effect. However, if the robot vacuum cleaner breaks down while inside the cabinet, or if the charging base for the robot vacuum cleaner breaks down, it may be difficult for the user to remove it for repair. To address this, the present invention may add a drawer (190) to the robot vacuum cleaner station (100).

[0422] In this regard, FIG. 23 is a drawing for explaining a state in which a drawer is provided in a robot cleaner station according to an embodiment of the present invention, and FIG. 24 is a drawing for explaining a state in which a drawer is withdrawn in a robot cleaner station according to an embodiment of the present invention.

[0423] Referring to FIGS. 23 and 24, the drawer (190) of the robot cleaner station (100) according to one embodiment of the present invention will be described as follows.

[0424] A robot cleaner station (100) according to one embodiment of the present invention may further include a drawer (190) that is drawn out from the housing (110).

[0425] When the drawer (190) is inserted into the housing (110), the door (126) can be closed when the robot cleaner (200) enters the mounting portion (120). In this case, the inside and outside of the housing (110) of the robot cleaner (200) can be blocked by the door (126).

[0426] Due to this, the robot cleaner (200) can prevent dust from flying out of the robot cleaner station (100) while collecting dust from the dust bin (220) inside the housing (110). In addition, it can prevent wastewater from leaking out of the robot cleaner station (100) while washing the mop (242).

[0427] The drawer (190) can be moved relative to the housing (110). For example, the housing (110) is fixedly connected to the kitchen cabinet (2), and the drawer (190) can be pulled forward from the housing (110).

[0428] At this time, the drawer (190) can be withdrawn with the mounting portion (120) provided inside. With this configuration, when the drawer (190) is withdrawn, the mounting portion (120) and / or the robot cleaner (200) can be withdrawn outside the kitchen cabinet (2).

[0429] At this time, when the drawer (190) is pulled out from the housing (110) while the door (126) closes the entrance (127), the robot cleaner (200) placed in the mounting portion (120) may be exposed to the outside.

[0430] Accordingly, according to the present embodiment, when maintenance such as repair or cleaning of the robot cleaner station (100) is required, the user can easily withdraw the mounting portion (120) and / or the robot cleaner (200) through the drawer (190) to expose the internal components of the robot cleaner station (100) or the robot cleaner (200).

[0431] Meanwhile, the drawer (190) according to one embodiment of the present invention can be withdrawn with the dust collection unit (140) provided therein. That is, the drawer (190) can be withdrawn together with the dust collection unit (140).

[0432] On the other hand, the dust collection unit (140) of the present invention can be pulled out from the housing (110) separately from the drawer (190). At this time, the pulling out direction of the dust collection unit (140) can be parallel to the pulling out direction of the drawer (190). For example, the pulling out direction of the dust bag drawer (144) can be parallel to the pulling out direction of the drawer (190).

[0433] In addition, the drawer (190) according to one embodiment of the present invention can be withdrawn with at least a portion of the mop washing unit (160) provided therein. That is, the drawer (190) can be withdrawn together with at least a portion of the mop washing unit (160). For example, the drawer (190) can be withdrawn together with the detergent container (163) and the waste container (164).

[0434] On the other hand, the detergent container (163) of the present invention can be withdrawn from the housing (110) separately from the drawer (190). At this time, the withdrawal direction of the detergent container (163) can be parallel to the direction in which the drawer (190) is withdrawn.

[0435] With this configuration, the robot cleaner station (100) according to one embodiment of the present invention may be provided with the drawer (190), dust collector (140), and detergent container (163) having the withdrawal directions all parallel.

[0436] Accordingly, the user can easily recognize the direction of withdrawal of the components of the robot cleaner station (100) of the present invention, and can easily withdraw them for repair and maintenance.

[0437]

[0438]

[0439] *The drawer (190) includes a drawer side wall (191), a fitting part (192), and a drawer rail (193).

[0440] The drawer side walls (191) are provided to be relatively movable with respect to the outer wall surface of the housing (110). For example, a pair of drawer side walls (191) may be arranged to face the outer wall surfaces of a pair of housings (110).

[0441] At this time, a pair of drawer side walls (191) may be placed closer to the inner side of the robot cleaner station (100) than the outer wall surface of a pair of housings (110). That is, a pair of drawer side walls (191) may be placed closer to the mounting portion (120) than the outer wall surface of a pair of housings (110).

[0442] At this time, a pair of drawer side walls (191) may be directly connected to the base (121) of the mounting portion (120). Alternatively, a pair of drawer side walls (191) may be connected by a drawer base (not shown), and the mounting portion (120) may be coupled to the upper side of the drawer base (not shown) and may move together.

[0443] Meanwhile, a dust collection unit (140) and / or a mop washing unit (160) may be placed between the drawer side wall (191) and the mounting portion (120). That is, based on the state in which the robot cleaner (200) is coupled to the mounting portion (120), a dust collection unit (140) and / or a mop washing unit (160) may be placed between the robot cleaner (200) and the drawer side wall (191).

[0444] With this configuration, there is an effect that the dust collection unit (140) and the mop washing unit (160) can be placed by utilizing the minimum horizontal space.

[0445] The fitting part (192) is provided on the drawer side wall (191), and at least one of a hose and a wire is detachably connected thereto. For example, the fitting part (192) is arranged on the drawer side wall (191), and a hose and / or a wire can be connected thereto.

[0446] The fitting part (192) is connected to the drawer side wall (191), one side of the fitting part (192) is positioned in the inner space of the drawer (190) than the drawer side wall (191), and the other side of the fitting part (192) is positioned on the outer side of the drawer side wall (191).

[0447] The fitting (192) is detachably connected to at least one of a hose and a wire. For example, the fitting (192) may be detachably connected to at least one of a water supply pipe connection to which a water supply pipe is connected, a drain pipe connection to which a drain pipe is connected, an exhaust pipe connection to which a steam exhaust pipe for discharging air inside the drawer (190) is connected, and a power connection to which a power source is connected.

[0448] At this time, the water supply pipe of the mop washing unit (160) and the water supply pipe connected to an external water source can be connected to both sides of the water supply pipe connection. In addition, the drain pipe of the mop washing unit (160) and the drain pipe connected to the upstream (25b) of the utensil trap of the kitchen cabinet (2) can be connected to both sides of the drain pipe connection.

[0449] That is, the fitting part (192) of the present invention may be a structure that detachably connects a water supply pipe and a drain pipe for direct drainage using a water source and a drain pipe provided in a kitchen cabinet (2) and a water supply pipe and a drain pipe inside a robot cleaner station (100).

[0450] Additionally, air exhaust pipes connected from the air exhaust port (172b) of the mop drying unit (170) can be connected to both sides of the exhaust pipe connection.

[0451] Accordingly, the air discharged from the mop drying unit (170) can be exhausted to the downstream (25c) of the utrap.

[0452] Additionally, the power connector may be connected to a wire to allow an external power source to be connected. The wire may be connected directly to the power connector, or may be connected using a wire connection means such as a connector or adapter.

[0453] The drawer rail (193) is arranged on the drawer side wall (191) and can guide the movement of the drawer side wall (191). The drawer rail (193) is fixedly connected to the drawer side wall (191) or is formed integrally with the drawer side wall (191) and can be connected to a rail installed on the outer wall (111) of the housing (110) to guide the movement path of the drawer side wall (191). Meanwhile, although the present invention describes that the drawer (190) and the housing (110) are provided with rails, it is not necessarily limited to the form of a rail, and may include all forms such as rollers, guide grooves, or guide ribs that can replace the rails.

[0480] Meanwhile, FIG. 26 is a perspective view for explaining the internal structure of a robot cleaner station according to an embodiment of the present invention, FIG. 27 is a view for illustrating a state in which a base and a washing plate are withdrawn from a robot cleaner station according to an embodiment of the present invention, FIG. 28 is a view for explaining a state in which a washing plate is separated from a base in a robot cleaner station according to an embodiment of the present invention, and FIG. 29 is a bottom view of a base in a robot cleaner station according to an embodiment of the present invention. In addition, FIG. 30 is a side cross-sectional view of a robot cleaner station according to an embodiment of the present invention, and FIG. 31 is an enlarged view for explaining an inclined guide surface and a lower inclined portion of a robot cleaner station according to an embodiment of the present invention, and FIG. 32 is an enlarged view showing a state in which a fixing groove and a base fixing protrusion of a robot cleaner station are combined according to an embodiment of the present invention, and FIG. 33 is a view for explaining a process in which a base is introduced into a robot cleaner station according to an embodiment of the present invention. In addition, FIG. 34 is an enlarged view for explaining a handle of a base in a robot cleaner station according to an embodiment of the present invention.

[0481]

[0482] Referring to FIGS. 26 to 34, a robot cleaner station according to an embodiment of the present invention is described as follows.

[0483] The base (121) of the present invention is provided so as to be withdrawable from the housing (110). At this time, the washing plate (122) can be withdrawn from the housing (110) together with the base (121).

[0484] In this regard, a base (121) of a robot cleaner station according to an embodiment of the present invention will be described. The base (121) further includes a handle (121e), a lower inclined portion (121f), a base wall (128d), and a fixing groove (128da). According to this configuration, the base (121) can be guided so as to be pulled out forward and retracted backward.

[0485]

[0486]

[0487] *The handle (121e) may be provided so that the user can grip it when withdrawing and retracting the base (121).

[0488] The robot cleaner station may be installed on the lower side of the kitchen cabinet (2). Accordingly, the user's field of vision may be limited to the front side (111a) and the upper side (113) of the housing (110). Therefore, in order for the user to withdraw the base (121) from the housing (110) while the robot cleaner station is installed, the handle (121e) needs to be positioned at the front of the base (121). That is, the handle (121e) may be positioned on the inclined portion (121b) of the base (121). The handle (121e) may be positioned between a pair of wheel guide portions (121ba). In addition, the handle (121e) may be positioned between the agitator receiving portion (121d) and the auxiliary wheel guide portion (121ba).

[0489] The shape of the handle (121e) will be described in detail. The shape of the handle (121e) may be an oval with a horizontal width greater than a vertical width. Accordingly, the handle (121e) can minimize the space it occupies in the front-back direction of the base (121).

[0490] Additionally, the handle (121e) may be composed of a recessed portion (121ea) and a cover portion (121eb). The recessed portion (121ea) may provide a space for accommodating a user's finger. For example, the recessed portion may be formed in a shape that is recessed downward from the base (121). As another example, the recessed portion may be formed in a through-hole structure. For example, if the space between the base (121) and the lower housing is narrower than the average finger thickness of the user, the recessed portion (121ea) may be designed to be formed through so that the user can easily insert his or her finger.

[0491] The cover portion (121eb) may be formed to protrude rearward from the front end of the recessed portion (121ea) and may be formed to cover at least a portion of the recessed portion (121ea). For example, the cover portion (121eb) may be formed to protrude in a curved or arched shape from the base (121). At least a portion of the cover portion (121eb) may be formed to overlap a certain portion with the auxiliary wheel guide portion (121ba).

[0492] Meanwhile, the user can insert his / her hand with the back of his / her hand facing upward to withdraw the base (121). The user's palm is positioned on the cover portion (121eb), and the fingers can be accommodated in the recessed portion (121ea) in a bent state. With this configuration, when the user grabs and pulls the handle, force is applied to the front end of the cover portion (121eb), and when the user applies upward force, force is applied to the lower side of the cover portion (121eb), so that the user can apply force both forward and upward. Through this, the user can withdraw the base (121) in a forward and upward diagonal direction.

[0493]

[0494]

[0495] *The housing (110) of the robot cleaner station according to an embodiment of the present invention may further include a door frame (126b). The door frame (126b) may be arranged on the front of the housing (110). An entrance (127) through which the robot cleaner is introduced may be formed in the door frame (126b). A door (126) for opening and closing the entrance (127) may be hingedly connected to the door frame (126b). In addition, an opening may be formed in the door frame (126b) to accommodate a dust bag drawer (144) and a detergent container (163).

[0496] The door (126) may be coupled to the lower side of the entrance (127). The hinge portion of the door (126) may be formed at the lower portion of the door frame (126b). Accordingly, when the base (121) is pulled out, a problem may arise in which the base (121) may get caught on the lower portion of the door frame (126b). To solve this problem, the door frame (126b) according to an embodiment of the present invention may include an inclined guide surface (126ba).

[0497] The inclined guide surface (126ba) can guide the movement of the base (121) so that the base (121) can be pulled out without interference from the door frame (126b). The inclined guide surface (126ba) can be arranged at the lower portion of the door frame (126b). More specifically, the inclined guide surface (126ba) can be formed at a portion of the door frame (126b) where the front end of the base (121) comes into contact. The inclined guide surface (126ba) can form a downward slope as it goes from the front end of the housing (110) to the rear.

[0498] A lower inclined portion (121f) may be formed on the lower surface of the base (121) in accordance with the shape of the inclined guide surface (126ba). The inclined guide surface (126ba) and the lower inclined portion (121f) may be in contact with each other while the base (121) is coupled to the housing (110). When the base (121) is pulled out, the lower inclined portion (121f) may be formed to move by contacting the inclined guide surface (126ba). Accordingly, the base (121) may be pulled out in a forward, upward diagonal direction.

[0499]

[0500] Meanwhile, the housing (110) may further include a base coupling portion (165). The base coupling portion (165) is detachably coupled to the base (121). The base coupling portion (165) may be positioned on the lower side of the coupling wall (123).

[0501] The base wall (128d) may be formed to extend vertically from the base bottom surface (121a) facing the bottom surface of the housing (110). The base wall (128d) may be positioned to face the base coupling portion (165) when the base (121) is coupled to the housing (110). When the base (121) is pulled by a user, the base wall (128d) may be separated from the base coupling portion (165) and moved away.

[0502] The base joint (165) can be formed to correspond to the shape of the base wall (128d). For example, the base wall (128d) can be formed in an arc shape with a predetermined curvature, and the base joint (165) can be formed in an arc shape so that the base wall (128d) is aligned and joined.

[0503]

[0504] *Meanwhile, the base joint (165) may be formed by being recessed radially outward from the joint wall (123). That is, the base joint (165) may be in the form of a groove formed on the lower side of the joint wall (123). With this configuration, the rear end of the base (121) may be fitted into and joined to the base joint (165).

[0505]

[0506] Meanwhile, fluid passing through the cleaning plate (122) may be introduced into the base (121). Additionally, a wastewater suction nozzle (165b) for draining the fluid may be inserted into the base wall (128d). The base (121) of the present invention is characterized by being designed to allow for inlet and outlet movement. However, if the base (121) is not accurately attached to the correct position, fluid may flow into the housing (110), which may cause a malfunction of the robot cleaner station.

[0507] To solve this problem, the base wall (128d) may include a configuration that fixes the combination of the base (121) and the housing (110). In addition, the base wall (128d) may include a configuration that guides the base (121) to be fixed in the correct position. That is, the base (121) may include a fixing groove (128da), a nozzle insertion port (128db), a guide coupling portion (not shown), and a magnet (not shown).

[0508] The fixed groove (128da) is formed to be sunken into the base wall (128d) and can fix the connection with the housing (110). The outer circumference of the base wall (128d) may refer to a portion that comes into contact with the base coupling portion (165) when the base (121) is coupled to the housing (110). At this time, the fixed groove (128da) may be formed to be sunken forward on the outer circumference of the base wall (128d). That is, the direction in which the fixed groove (128da) is sunken may coincide with the direction in which the base (121) is pulled out. The fixed groove (128da) may guide the base (121) to be inserted in the correct direction when the user pulls out or inserts the base (121). For example, a pair of fixed grooves (128da) may be formed. A nozzle insertion port (128db) to be described later may be arranged between the pair of fixed grooves (128da).

[0509] The base fixing protrusion (165a) may be formed on the base coupling portion (165) of the housing (110). The base fixing protrusion (165a) may be formed to protrude forward from the base coupling portion (165) of the housing (110). When the base (121) is coupled to the housing (110), the base fixing protrusion (165a) may be accommodated in the fixing groove (128da). The shape of the base fixing protrusion (165a) may be formed to correspond to the fixing groove (128da). For example, a pair of base fixing protrusions (165a) may be formed. A sewage suction nozzle (165b) may be arranged between the pair of base fixing protrusions (165a).

[0510] A magnet (not shown) may be placed in at least one of the fixing groove (128da) and the base fixing protrusion (165a). The magnet (not shown) may generate a magnetic field. The magnet (not shown) may generate an attractive force to allow the base (121) to be coupled to the correct position. In addition, the magnetic field generated by the magnet (not shown) may be detected by a washing tank coupling sensor (not shown). Through this, the magnet (not shown) may guide the base (121) to be coupled to the correct position. In addition, if the base (121) is not coupled to the correct position, the robot cleaner station may not operate, thereby preventing a malfunction.

[0511]

[0512] Meanwhile, the mop is washed on the washing plate (122), and the fluid used to wash the mop passes through the washing plate (122) and flows into the base (121). More precisely, the fluid can be collected in the washing tank (128) arranged on the bottom surface (121a) of the base.

[0513] Meanwhile, the washing tank (128) can receive liquid (washing water) that has passed through the washing plate (122). The washing tank (128) can be placed on the rear side of the base (121a). For example, the washing tank (128) can be formed integrally with the base bottom surface (121a).

[0514] Specifically, liquid that has passed through the main passage hole (122b) or the side passage hole (122d) formed in the washing plate (122) may be introduced into the washing tank (128). The washing tank (128) may be composed of a bottom of the washing tank where the fluid collects and a base wall (128d) surrounding the bottom of the washing tank. In addition, the washing tank (128) may have a concave shape downward. A reservoir groove where the fluid collects may be formed in the washing tank. The opening of the wastewater suction nozzle (165b) described later may be arranged to face the reservoir groove.

[0515]

[0516] The fluid collected in the washing tank (128) can be discharged to the outside through the sewage suction nozzle (165b). The sewage suction nozzle (165b) can be connected to the sewage suction pipe (164c) provided in the mop washing unit (160). The liquid introduced through the sewage suction nozzle (165b) can flow into the sewage tank (164).

[0517] The sewage suction nozzle (165b) may be formed to protrude from the base joint (165). For example, the sewage suction nozzle (165b) may be formed to protrude forward and then be bent downward. In this case, when the base (121) is coupled to the housing (110), the sewage suction nozzle (165b) may be opened toward the base bottom surface (121a). More specifically, the sewage suction nozzle (165b) may be opened toward the water storage groove. Through this configuration, sewage can be discharged even when the fluid surface level is low.

[0518] The nozzle insertion port (128db) may be formed in the base wall (128d). For example, the nozzle insertion port (128db) may be positioned between a pair of fixed grooves (128da). When the base (121) is coupled to the housing (110), a sewage suction nozzle (165b) may be inserted into the nozzle insertion port (128db). The diameter of the nozzle insertion port (128db) may be larger than the diameter of the sewage suction nozzle (165b). For example, the diameter of the nozzle insertion port (128db) may be sufficiently large so that a sewage suction nozzle (165b) bent downward may be inserted therein.

[0519]

[0520] Referring to FIGS. 32 and 33, the withdrawal and insertion process of the base (121) is described as follows.

[0521] First, when withdrawing the base (121), the user holds the handle (121e). At this time, the user's palm is positioned on the cover portion (121eb) and the fingers can be accommodated in the recessed portion (121ea). Meanwhile, the user is positioned in front of the robot cleaner station (100), and the user's shoulder is positioned higher on the ground than the user's hand. Therefore, when the user pulls the handle (121e), the base (121) begins to be withdrawn toward the front of the housing (110). At this time, the lower inclined portion (121f) of the base (121) begins to slide while in contact with the inclined guide surface (126ba) of the housing (110). The inclined guide surface (126ba) can guide the movement so that the base (121) is withdrawn in a forward, upward diagonal direction. As a result, the base (121) can be withdrawn without interference with the door frame (126b). When the base (121) is partially withdrawn, the fixing groove (128da) of the base wall (128d) and the base fixing protrusion (165a) of the housing (110) begin to separate. In addition, the nozzle insertion port (128db) and the wastewater suction nozzle (165b) located in the base wall (128d) begin to separate from each other. When the base (121) is completely withdrawn, the base fixing protrusion (165a) comes out of the fixing groove (128da), and the wastewater suction nozzle (165b) comes out of the nozzle insertion port (128db). At this time, it is possible to detect that the base (121) has been withdrawn through the magnetic force of a magnet (not shown).

[0522] On the other hand, when reinserting the base (121), the user uses the handle (121e) to push the base (121) toward the housing (110), and in this process, the base fixing groove (128da) and the base fixing protrusion (165a) are re-engaged. At the same time, the wastewater suction nozzle (165b) is accurately inserted into the nozzle insertion port (128db), and guided by the inclined guide surface (126ba), the base (121) enters the inside of the housing (110). When the base (121) is completely reinserted, the magnetic force of the magnet (not shown) is activated to pull the base (121) into the correct position, and the fact that the base (121) has been reinserted can be detected.

[0523] If the base (121) is not fully inserted, the lower slope (121f) of the base (121) is not precisely engaged with the slope guide surface (126ba), and the base fixing protrusion (165a) or the sewage suction nozzle (165b) comes into contact with the base wall (128d), so that the user can easily confirm that the base (121) is not fixed in the correct position.

[0524]

[0525] The base (121) according to an embodiment of the present invention can be withdrawn or introduced along the inner wall (124).

[0526] A drawer guide (not shown) may be formed to protrude from the inner wall (124). For example, the drawer guide (124)a) may be formed to protrude from a pair of inner walls (124) in a direction facing each other. At this time, the drawer guide (not shown) may be formed to form an incline with respect to the ground. At this time, the drawer guide (not shown) may be formed so that its height from the ground increases from the front to the rear.

[0527] A drawer guide (not shown) can guide the movement of the washing tank (128). When the washing tank (128) is introduced into the housing (110), guide coupling parts (not shown) arranged on both sides of the washing tank (128) are fitted with the drawer guide (not shown) and can guide the rearward movement of the washing tank (128). Thereafter, when the washing tank (128) is coupled to the housing (110), the drawer guide (not shown) and the guide coupling parts (not shown) are coupled to each other to support the washing tank (128).

[0528] With this configuration, the washing tank (128) can be attached to the exact position along the drawer guide (not shown) with a simple action of the user pushing the base (121).

[0529]

[0530] The washing tank (128) may be provided with a guide coupling part (not shown). Specifically, guide coupling parts (not shown) may be provided on both left and right sides of the washing tank (128).

[0531] The guide joint (not shown) is formed in a plate shape having a predetermined thickness and protrudes from both sides of the washing tank (128), and can be formed to correspond to the shape of the drawer guide (not shown). For example, the guide joint (not shown) can be formed to have the same slope as the drawer guide (not shown), and can be formed at a position where the upper surface of the drawer guide (not shown) and the lower surface of the guide joint (not shown) are in contact with each other when the washing tank (128) is coupled.

[0532] Therefore, when the washing tank (128) is introduced into the interior of the housing (110), the guide coupling portion (not shown) is fitted with the drawer guide (not shown) and can guide the rearward movement of the washing tank (128).

[0533] Meanwhile, the mop washing unit (160) further includes a washing tank combination sensor (not shown). The washing tank combination sensor (not shown) is placed in the sewage suction pipe (164c) or the base combination unit (165) and can detect the combination of the washing tank (128).

[0534] The washing tank combination sensor (not shown) can be placed at a position facing the magnet (128c).

[0535] For example, the washing tank coupling sensor (not shown) may be a Hall sensor. The Hall sensor can detect a magnetic field generated by the magnet (128c). Through this, the washing tank coupling sensor (not shown) can detect the presence of the magnet (128c).

[0536] Through this, when the washing tank (128) is connected to the correct position of the base connecting part (165), the washing tank connecting sensor (not shown) can detect that it has been connected to the correct position.

[0537] At this time, the control unit (not shown) of the robot cleaner station (100) can perform washing of the mop (242) when it is detected that the washing tank (128) is connected to the correct position.

[0538] Meanwhile, the control unit (not shown) of the robot cleaner station (100) can restrict the operation of the mop cleaning unit (160) when the cleaning tank (128) is not attached to the correct position. In addition, the control unit (not shown) of the robot cleaner station (100) can notify the user that the cleaning tank (128) is not attached through a display (not shown) or a speaker (not shown).

[0539] Therefore, according to the present invention, after washing the washing tank (128), it is possible to accurately connect it along the drawer guide (not shown) with just a simple action of pushing the washing tank (128), and whether it is connected in the correct position can be detected through the washing tank connection sensor (not shown), so there is an effect of preventing wastewater collected in the washing tank (128) from leaking out due to incorrect connection of the washing tank (128).
