Description

Robot Vacuum Station

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

[0002]

[0003] 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.

[0004] 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.

[0005] 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 a 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.

[0006] 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.

[0007] 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.

[0008] 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.

[0009] In this regard, Chinese Utility Model Registration No. CN 2192708414 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.

[0010] 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.

[0011] 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.

[0012] 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.

[0013] 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 out during the process of collecting dust in the robot vacuum cleaner's dust bin, and sewage may leak during the process of washing the robot vacuum cleaner's mop.

[0014] Meanwhile, Japanese registered patent JP4916266B2 discloses a building that utilizes the space below the wall to collect dust from the dust bin of a robot vacuum cleaner.

[0015] The above building has a dust collection device built into the lower space of the wall, so that when a robot vacuum cleaner approaches, it can collect dust inside the robot vacuum cleaner's dust bin.

[0016] However, in the case of the above building, since air is simply sucked in from the lower side of the wall, dust is emptied without maintaining an airtight seal in relation to the dustbin of the robot vacuum cleaner, so there is a limitation that dust may fly indoors.

[0017] Additionally, the building cannot power the robot vacuum cleaner and must be equipped with a robot vacuum cleaner charging station, so the effect of increasing indoor space efficiency is limited.

[0018] In addition, if the height of the lower space is different depending on the building, the support height of the dust collector cannot be adjusted accordingly, and if a dust collector lower than the height of the lower space is used, there is a limitation in that the dust collector cannot be fixed.

[0019]

[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 vacuum cleaner station that stably fixes the station by adjusting the height of the supporter to match the height of the kitchen cabinet when installing the station.

[0027] In addition, the purpose is to provide a robot vacuum cleaner station that can easily adjust the height of the rear supporter of the station, which is difficult for workers to reach, when installing the station.

[0028]

[0029] In order to achieve the above-described purpose, a robot cleaner station according to the present invention comprises: a housing disposed at the bottom of a kitchen cabinet; and a coupling part disposed within the housing and accommodating a robot cleaner; wherein the housing comprises: a pair of outer walls disposed on both left and right sides of the coupling part; and a rear supporter provided on each of the pair of outer walls and supporting the kitchen cabinet.

[0030] At this time, the rear supporter includes a rear support part that comes into contact with the kitchen cabinet according to the up-and-down movement, and the rear support part moves up and down according to the rotation of at least one gear.

[0031] At this time, the rear supporter further includes a head part having one longitudinal end coupled with a work tool; and a worm gear part that rotates together with the rotation of the head part.

[0032] Through this, the head and worm gear can be rotated by the operating force of the work tool.

[0033] In addition, the rear supporter may further include a helical gear portion that meshes with the worm gear portion and is coupled to the rear support portion. Through this, the rotational force applied through the worm gear portion can be transmitted to the support portion, and the support portion can be raised or lowered.

[0034] Meanwhile, the housing further includes a pair of front supporters, each of which is coupled to a pair of outer walls, and the front supporters include a supporter body; and an operating hole formed in the supporter body to operate the rear supporter.

[0035] At this time, the extension of the rotation axis of the head can pass through the operation hole. Through this, the worker can control the height of the rear supporter using a work tool at the front of the robot cleaner station.

[0036] Meanwhile, the outer wall includes a supporter installation part in which the rear supporter is installed, and the supporter installation part can be rotatably coupled to the worm gear part.

[0037] Additionally, the supporter installation portion can rotatably accommodate at least a portion of the helical gear portion.

[0038] Meanwhile, the rear supporter may include a first rear supporter that is provided to be movable in an up-and-down direction from the outer wall and is supported in contact with the kitchen cabinet; and a second rear supporter that is provided to be movable in an up-and-down direction from the outer wall and is supported in contact with the floor of the kitchen.

[0039] Meanwhile, the outer wall may include an outer wall cover; and a wall portion coupled to the outer wall cover to provide a space therein in which at least a portion of the rear supporter is accommodated.

[0040]

[0041] 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.

[0042] 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.

[0043] Additionally, since all sides except the front are covered by kitchen furniture, it has the effect of providing aesthetic appeal to the user in terms of interior design.

[0044] 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 workload.

[0045] 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.

[0046] Additionally, since detergent can be added as needed, it has the effect of increasing the cleaning effect of the mop.

[0047] 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.

[0048] In addition, after washing the mop of the robot vacuum cleaner, it can automatically dry the mop by supplying hot air to the mop, which has the effect of preventing bad odors from being generated due to the wet mop.

[0049] Additionally, during the process of drying the mop, the air after drying is discharged downstream of the yutrap, which has the effect of preventing bad odors from flowing back.

[0050] Additionally, during installation or removal, the height of the supporter can be adjusted with a simple operation of turning the control unit to match the height of the kitchen cabinet, thereby providing the effect of stably fixing it.

[0051] Additionally, during installation or removal, it is possible to easily adjust the height of the rear supporter, which is difficult for workers to reach, by simply inserting a work tool from the front and turning it.

[0091] In addition, the following examples are provided to provide a more complete explanation to a person having average knowledge in the art, and the shapes and sizes of elements in the drawings may be exaggerated for a clearer explanation.

[0092]

[0093] 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.

[0094] 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.

[0095] Additionally, the kitchen cabinet (2) may be equipped with a worktop that can serve as a sink, cooking surface, or work surface.

[0096] 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.

[0097] In general, a kitchen cabinet (2) with a width of 600 mm in the front-to-back direction and a width of 600 mm in the front-to-back direction can be used.

[0098] A cleaner system (1) according to another embodiment of the present invention may be installed 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 (160a) 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.

[0099] 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).

[0100] 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). At this time, a space may be formed between the kitchen floor and the lower plate (23) depending on the height of the pedestal (21).

[0101] Alternatively, it is also possible to secure the kitchen cabinet (2) to the wall of the building without a pedestal (21). In this case, a space may be formed between the kitchen floor and the lower plate (23).

[0102] The vacuum cleaner system (1) according to an embodiment of the present invention is mounted in the space between the kitchen floor and the lower plate (23) as described above (hereinafter, referred to as the mounting space (24)).

[0103] For example, the mounting space (24) may have a height of 200 mm or less, and typically a height of 160 mm or less.

[0104] Therefore, according to the present invention, since the cleaner system (1) is placed in the lower space of the kitchen cabinet (2), there is an effect of minimizing the exposure of the cleaner system (1) to the outside.

[0105] In addition, compared to placing a charging stand for a robot vacuum cleaner in a certain space in a living room, room, or kitchen, the vacuum cleaner system (1) is placed in an unused space created by kitchen furniture (2) without taking up a separate space, thereby maximizing space efficiency.

[0106]

[0107] Meanwhile, a kitchen cabinet (2) or the structure is provided with a drain pipe (25) for draining liquid used in cooking or water used in washing dishes. At least a part of the drain pipe (25) may be arranged in the storage space formed between the upper plate (22) and the lower plate (23). Typically, the drain pipe (25) may be connected to a drain formed in a sink basin (22a). The drain pipe (25) includes a drain trap (25a) for preventing backflow of polluted gas or foul odor. The drain trap (25a) may be arranged in the storage space. Liquid flowing through the drain may flow downward by gravity in the upstream (25b) of the drain trap, accumulate in the drain trap (25a), and when the water rises above a predetermined level set by the drain trap (25a), flow downward along the downstream (25c) of the drain trap and be discharged into the sewer.

[0108] The cleaning system (1) according to an embodiment of the present invention can wash and dry the mop (242) of the robot cleaner (200) using the drain pipe (25) as described above.

[0109] Additionally, the kitchen cabinet (2) may be equipped with a water supply pipe (160a). Through the water supply pipe (160a), tap water (or purified water) may be supplied to the cleaner system (1).

[0110] Below, the specific structure of the vacuum cleaner system (1) will be described.

[0111]

[0112] Meanwhile, FIGS. 3 to 5 illustrate drawings for explaining a cleaning system according to an embodiment of the present invention.

[0113] A vacuum cleaner system (1) according to an embodiment of the present specification may include a robot vacuum cleaner station (100) and a robot vacuum cleaner (200).

[0114] The vacuum cleaner system (1) includes a robot vacuum cleaner station (100). A robot vacuum cleaner (200) can be coupled to the robot vacuum cleaner station (100). Specifically, the robot vacuum cleaner (200) can enter the front of the robot vacuum cleaner station (100) and can be accommodated inside the robot vacuum cleaner station (100). The robot vacuum cleaner station (100) can remove dust from a dust bin (220) of the robot vacuum cleaner (200). The robot vacuum cleaner station (100) can wash a rotating cleaning unit (240) of the robot vacuum cleaner (200). The robot vacuum cleaner station (100) can dry the rotating cleaning unit (240) of the robot vacuum cleaner (200). The robot vacuum cleaner station (100) can supply power to the robot vacuum cleaner (200).

[0115]

[0116] Meanwhile, FIGS. 6 to 9 disclose drawings for explaining a robot cleaner in a cleaner system according to an embodiment of the present invention.

[0117] The structure of the robot vacuum cleaner (200) is described below with reference to FIGS. 6 to 9.

[0118] 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.

[0119] 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.

[0120] 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.

[0121] 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.

[0122] 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).

[0123] 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).

[0124] 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.

[0125] 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).

[0126] When viewed from above or below, the body (210) can be formed in various shapes, such as circular, oval, or square.

[0127] 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.

[0128] 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.

[0129] The lower body may be formed with an intake (211) for air intake and a hole for accommodating a pair of wheels (260).

[0130] 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).

[0131] 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.

[0132] 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.

[0133] 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.

[0134] 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.

[0135] Although not shown, 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).

[0136] 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).

[0137]

[0138] A dust bin (220) may be provided to suck in external dust and air and store the dust.

[0139] 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.

[0140] 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 detachably according to an embodiment.

[0141] 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.

[0142] 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).

[0143] 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).

[0144] With this configuration, when the dust collecting motor (152) 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 (152), 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).

[0145]

[0146] 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).

[0147] 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.

[0148] 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).

[0149] 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.

[0150] 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 of a pair of rotating plates (241), thereby allowing the liquid inside the water tank (230) to be supplied to a pair of mops (242).

[0151] 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 turntable, and the other branched end may be located on the upper side of the right turntable.

[0152] 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).

[0153]

[0154] The rotary cleaner (240) includes a rotary plate (241) and a mop (242).

[0155] 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.

[0156] 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.

[0157] 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.

[0158] A pair of rotating plates (241) can be symmetrical to each other.

[0159] The mop (242) can be attached to the lower side of the turntable (241) so as to face the floor surface (B).

[0160] 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).

[0161] 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).

[0162] 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.

[0163]

[0164] 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.

[0165] 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).

[0166]

[0167] 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).

[0168] The wheel (260) is provided on the body (210) and can roll on the floor surface.

[0169] 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.

[0170] 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.

[0171] 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.

[0172] 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.

[0173] 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).

[0174] 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).

[0175] 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).

[0176] Additionally, the battery can supply power to the sensor unit (not shown) and the control unit (not shown).

[0177] 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).

[0178]

[0179] 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.

[0180] Referring to FIGS. 10 and 11, the robot cleaner station (100) of the present invention is described as follows.

[0181] A robot cleaner (200) can be accommodated in a robot cleaner station (100). A robot cleaner (200) can be coupled to a coupling portion (120) of the robot cleaner station (100).

[0182] The robot vacuum cleaner station (100) may include a housing (110).

[0183] 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.

[0184] The housing (110) may have a space formed therein that can accommodate a coupling part (120), a dust collection path (130), a dust collection part (140), a dust collection motor (152), a mop washing part (160), a mop drying part (170), and a circulation path (125a).

[0185] 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 (24) formed between the lower side plate (23) of the kitchen cabinet (2) and the floor of the kitchen.

[0186] The housing (110) includes a pair of outer walls (111) facing each other. The outer walls (111) may be configured to include a surface formed along the direction of gravity.

[0187] A pair of outer walls (111) can be installed at a predetermined interval on the lower side of the kitchen cabinet (2). At this time, the housing (110) further includes a floor surface facing the floor of the kitchen, and the pair of outer walls (111) can be connected through the floor surface.

[0188] With this configuration, components of the robot cleaner station (100) can be accommodated inside the housing (110) (between a pair of outer walls (111)).

[0189] Specifically, the outer wall (111) may include an outer wall cover (111a), a wall portion (111b), and a supporter installation portion (111c).

[0190] At this time, the outer wall cover (111a) is positioned at the outermost left and right sides of the robot cleaner station (100) to form the exterior, and can be combined with the wall portion (111b) to provide a space to accommodate gear parts of the rear supporters (114, 115) inside. That is, a supporter installation portion (111c) in which at least a portion of the rear supporters (114, 115) is installed and accommodated can be provided between the outer wall cover (111a) and the wall portion (111b). The supporter installation portion (111c) will be described later together with the rear supporters (114, 115).

[0191] In addition, a drawer (190) may be arranged between a pair of wall portions (111b). That is, a pair of wall portions (111b) may be arranged to face a pair of drawer side walls (191), and a coupling portion (120), a dust collection path (130), a dust collection portion (140), a dust collection motor (152), a mop washing portion (160), a mop drying portion (170), and a circulation path portion (180) may be arranged between a pair of drawer side walls (191).

[0192] The drawer (190) will be described later.

[0193] Meanwhile, the housing (110) may further include a bottom surface facing the kitchen floor and an upper surface (113) facing the lower plate (23) of the kitchen cabinet (2) (see Fig. 34). In addition, the housing (110) may further include a rear surface connecting the bottom surface and the upper surface.

[0194] With this configuration, the housing (110) can block the upper and lower sides of the robot cleaner station (100). 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) can be prevented from being contaminated.

[0195] 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).

[0196] 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).

[0197] 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).

[0198] 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.

[0199] That is, the outer walls of the robot cleaner station (100) can be placed on the left and right sides, respectively.

[0200] 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 (111), 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 (26) 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.

[0201] Through this, the exposure of the robot cleaner station (100) and the robot cleaner (200) to the outside can be minimized.

[0202] 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.

[0203] Meanwhile, in one embodiment of the present invention, the height of the upper end of the outer wall (111) may be formed lower than the height of the upper side (113) of the housing (110). Accordingly, a height difference may occur between the upper end of the outer wall (111) and the upper side of the housing (110).

[0204] Accordingly, a space may be formed between the upper end of the outer wall (111) and the upper side of the housing (110) through which a water supply hose connected to a water supply pipe (160a) passes, a space may be formed through which a drain hose for discharging waste water generated after washing the mop (242) passes, and a space may be formed through which a hose for discharging moisture generated during the drying process of the mop (242) passes. In addition, a space may be formed between the upper end of the outer wall (111) and the upper side of the housing (110) through which a wire for supplying power to the robot cleaner station (100) passes.

[0205] Therefore, according to the present invention, when the drawer (190) is pulled out, the hose and wire can be pulled out together with the drawer, thereby providing convenience to the user.

[0206] Meanwhile, the housing (110) according to the present invention further includes a front supporter (112) that is provided to be in contact with the kitchen cabinet (2).

[0207] The front supporter (112) is placed between the kitchen floor and the lower plate (23) of the kitchen cabinet (2), and can support the kitchen floor and the lower plate (23) of the kitchen cabinet (2) by making contact with them. Through this, the lower plate (23) of the kitchen cabinet (2) can be supported, thereby maintaining the space where the robot cleaner station (100) is installed, and at the same time, the robot cleaner station (100) can be fixed to the kitchen cabinet (2).

[0208] The front supporter (112) is hinge-connected to the outer wall (111). Specifically, the front supporter (112) is rotatably connected to the front end of the outer wall (111).

[0209] Referring to FIG. 36, the front supporter (112) includes a supporter body (112a), a hinge portion (112b), a support portion (112c), a height adjustment portion (112d), and an operation hole (112e).

[0210] The supporter body (112a) forms the exterior of the front supporter (112) and can be positioned at the front of the robot cleaner station (100) and exposed to the outside. The supporter body (112a) is formed in a similar column shape, but at least one corner can be curved. With this configuration, the supporter body (112a) can provide a supporting force that supports the space between the kitchen floor and the lower plate (23) of the kitchen cabinet (2).

[0211] The hinge portion (112b) may be formed to extend radially outward from the supporter body (112a) and be hinge-joined with the outer wall (111). At this time, the hinge portion of the front supporter (112) may be inserted into the inner side of the outer wall (111) and may be hinge-joined with a pin or protrusion formed on the inside of the outer wall (111) to form a hinge axis. Accordingly, the hinge axis of the front supporter (112) may be formed on the inside of the outer wall (111).

[0212] The support member (112c) is arranged on the upper side of the supporter body (112a) and can contact and support the lower plate (23) of the kitchen cabinet (2). For example, the support member (112c) may be formed in a flat shape so that the upper surface supports the lower plate (23) of the kitchen cabinet (2), and the lower surface may be supported by the supporter body (112a).

[0213] The height adjustment member (112d) is rotatably connected to the supporter body (112a), and can adjust the height of the support member (112c) according to the rotation. Accordingly, when the worker turns the height adjustment member (112d), the support member (112c) moves in the up-and-down direction, so that it can be supported by contacting the lower plate (23) of the kitchen cabinet (2), or can be released from contact with the lower plate (23).

[0214] With this configuration, when the front supporter (112) is positioned at the front of the outer wall (111), when the worker turns the height adjustment part (112d), the support part (112c) is lowered, releasing the fixation between the front supporter (112) and the kitchen cabinet (2). Thereafter, when the worker holds and turns the supporter body (112a), the front supporter (112) can be rotated outward in the left and right directions of the robot cleaner station (100) at the front end of the outer wall (111). Accordingly, the front of the outer wall (111) can be opened.

[0215] Therefore, according to the present invention, the front supporter (112) can block the front end of the outer wall (111) and open the blocked front end of the outer wall (111) by rotation.

[0216] An operation hole (112e) may be formed in the supporter body (112a) to operate the rear supporters (114, 115) to be described later. Specifically, the operation hole (112e) may be formed to penetrate the supporter body (112a) along the front-back direction of the robot cleaner station (100) when the front supporter (112) is arranged in front of the outer wall (111). For example, the operation hole (112e) may be formed to penetrate the supporter body (112a) along the front-back direction of the robot cleaner station (100), and two operation holes (112e) may be formed in parallel, one above the other. At this time, an imaginary line penetrating each of the operation holes (112e) formed in parallel may be arranged on the same line as the head portion (114d) of the first rear supporter (114) and the head portion (115d) of the second rear supporter (115).

[0217] With this configuration, a work tool including a driver, etc. can pass through the operation hole (112e) and be coupled to the head (114d, 115d) of the rear supporter (114, 115) described later, and the operation force of the work tool can be applied to the head (114d, 115d).

[0218] Accordingly, the present invention can provide convenience in that the worker can operate the rear supporter (114, 115) that is out of reach by a simple action of inserting the work tool into the operation hole (112e).

[0219]

[0220] The robot vacuum cleaner station (100) may include a coupling part (120).

[0221] The robot cleaner (200) and the robot cleaner station (100) can be physically, electrically and / or axially connected through a coupling portion (120).

[0222] The coupling part (120) can be placed inside the housing (110). At this time, the coupling part (120) of the present embodiment is provided so as to be withdrawable from the housing (110) through a drawer (190).

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

[0224] An entrance (127) through which a robot cleaner (200) is introduced may be formed in the joint (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 floor member (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) is arranged at the top of the entrance (127) and may be provided with a rotation axis along a direction parallel to the floor member (121). The door (126) may be hingedly connected to the housing (110). Alternatively, the door (126) may be hingedly connected to the side wall (124) of the coupling portion (120). The door (126) may be rotated by the door driving unit (126a). For example, the door driving unit (126a) may be a motor.

[0228] 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.

[0229] The door (126) can keep the entrance (127) closed when the robot cleaner (200) is accommodated in the coupling portion (120). In addition, when the robot cleaner (200) starts to move from the coupling 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 robot cleaner station (100).

[0230]

[0231] The joint (120) may include a receiving space (S), a floor member (121), a joint wall (123), and a side wall (124).

[0232] A robot cleaner (200) can be accommodated in the accommodation space (S) of the coupling portion (120). For example, the accommodation space (S) may refer to a space surrounded by a floor member (121), a coupling wall (123), and a side wall (124). As another example, the accommodation space (S) may refer to a space surrounded by a floor member (121), a cleaning member (122), a coupling wall (123), and a side 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 coupled 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).

[0233] The floor member (121) can be arranged so that the robot cleaner station (100) comes into 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). The floor member (121) can include a floor member body (121a), an inclined portion (121b), a wheel coupling portion (121c), an agitator receiving portion (121d), and a cleaning member coupling portion (121e).

[0234] The floor member body (121a) can form the overall appearance of the floor member (121). An inclined portion (121b), a wheel coupling portion (121c), an agitator receiving portion (121d), and a cleaning member coupling portion (121e) can be arranged on the floor member body (121a).

[0235] The floor member body (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.

[0236] A circulation path (125a) may be provided inside the floor member body (121a). Accordingly, air discharged from the dust collection motor (152) may flow through the circulation path (125a) formed inside the floor member body (121a) and be exhausted to the exhaust port (125b).

[0237] The slope (121b) can be placed at the entrance through which the robot cleaner (200) climbs in the floor member body (121a).

[0238] 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).

[0239] A wheel guide portion (121ba) may be provided on the slope portion (121b).

[0240] 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.

[0241] An auxiliary wheel guide part (121bb) may be provided on the slope part (121b).

[0242] 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).

[0243] 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).

[0244] 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).

[0245] 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).

[0246] The agitator receiving portion (121d) can receive the agitator (250) of the robot cleaner (200). Specifically, the agitator receiving portion (121d) can provide a space in which the agitator (250) of the robot cleaner (200) is received while the wheel (260) of the robot cleaner (200) is secured to the wheel coupling portion (121c).

[0247] The agitator receiving portion (121d) may include a recessed portion (121da) and a protruding portion (121db).

[0248] The recessed portion (121da) may be formed to be recessed in the floor member (121). The recessed portion (121da) may form a receiving space (121dc) 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 (121dc) of the recessed portion (121da).

[0249] The accommodation space (121dc) of the recessed portion (121dc) can be communicated with the accommodation space (S) of the connecting portion (120).

[0250] An exhaust port (125b) may be formed on one side of the recessed portion (121da). Specifically, the exhaust port (125b) may be formed on the side of the recessed portion (121da). Accordingly, air discharged from the dust collecting motor (152) and passing through the circulation path (125a) may be exhausted into the receiving space (121dc) of the recessed portion (121da) through the exhaust port (125b).

[0251] The protrusion (121db) may be formed to protrude from the bottom member (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 (121dc) of the recessed portion (121da), the protrusion (121db) may be arranged to be spaced apart from the body (210) of the robot cleaner (200) by a predetermined distance.

[0252] The protrusion (121db) can guide the air discharged through the exhaust port (125b) to the suction part (211) of the robot cleaner (200). Through this, the air discharged into the receiving space (121dc) of the recessed part (121da) can be guided to the suction part (211) of the robot cleaner (200) by the protrusion (121db).

[0253] 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 bottom member body (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).

[0254] An exhaust port (125b) may be formed in the agitator receiving portion (121d). The exhaust port (125b) may be formed on a side surface of the agitator receiving portion (121d). The exhaust port (125b) may connect the recessed portion (121da) of the agitator receiving portion (121d) and the dust collecting motor (152) via a circulation path (125a). The recessed portion (121da) of the agitator receiving portion (121d) and the circulation path (125a) may be communicated via the exhaust port (125b). Therefore, air discharged from the dust collecting motor (152) may pass through the exhaust port (125b) and be discharged to the recessed portion (121da) of the agitator receiving portion (121d).

[0255]

[0256] 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 from the rear side of the floor member (121) in a direction intersecting with the floor member (121). The joining wall (123) can extend in a vertical direction from the rear side of the floor member (121). The joining wall (123) can be formed to correspond to the shape of the robot cleaner (200). For example, the joining wall (123) can be formed in an arc shape having 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).

[0257]

[0258] A dust passage hole (123a) may be formed in the coupling part (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 coupling wall (123) of the coupling part (120) 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 the robot cleaner (200). The dust passage hole (123a) may be communicated with a dust outlet (141b) 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) to allow dust in the dust bin (220) to flow into the dust collection unit (140). The dust passage hole (123a) may be formed to correspond to the shape of the dust discharge port (141b) of the dust bin (220). The dust passage hole (123a) may be formed to communicate with the dust collection path (130). The air sucked into the dust passage hole (123a) may flow through the dust collection path (130) and then be exhausted through the exhaust unit (125).

[0259]

[0260] The power supply terminal (123b) can supply power to the robot cleaner (200) coupled to the coupling portion (120). The power supply terminal (123b) can be electrically connected by contacting the charging terminal (280) of the robot cleaner (200). The power supply terminal (123b) can be arranged in the coupling portion (120). Specifically, the power supply terminal (123b) can be arranged in 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).

[0261]

[0262] The robot cleaner station (100) may further include a water supply nozzle (123c).

[0263] 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 (160a) of the kitchen cabinet (2) to the storage space inside the water tank (230) of the robot cleaner (200).

[0264]

[0265] The side wall (124) is a configuration that spatially divides the receiving space (S) of the coupling portion (120) from the components of the robot cleaner station (100). A pair of side walls (124) may be arranged on the left and right sides of the floor member (121). The side walls (124) may be connected to both ends of the coupling wall (123). The side walls (124) may extend in a direction intersecting the floor member (121) from the left and right sides of the floor member (121). Specifically, the side walls (124) may extend in a vertical direction from the left and right sides of the floor member (121). The height of the side walls (124) may be formed to correspond to the height of the pedestal (21). Specifically, the height of the side walls (124) may be formed to be the same as the height of the pedestal (21).

[0266] Meanwhile, various components such as a dust collection path (130), a dust collection unit (140), a dust collection motor (152), a detergent container (163), and a waste container (164) can be arranged on the outside of the side wall (124). Specifically, the dust collection unit (140), the detergent container (163), and the waste container (164) can be accommodated in the space between the side wall (124) and the outer wall surface of the housing (110).

[0267] The dust collection unit (140) and the detergent container (163) can be separated from the space between the side wall (124) and the outer wall surface of the housing (110) in a sliding manner (see FIG. 19). The left-right width of the dust collection unit (140) and the detergent container (163) can be formed to correspond to the distance between the side wall (124) and the outer wall surface of the housing (110).

[0268]

[0269] The cleaning member coupling portion (121e) is configured to secure the cleaning member (122) described later. The cleaning member coupling portion (121e) may be positioned on the rear side of the bottom member body (121a). The cleaning member coupling portion (121e) may be formed to correspond to the cleaning member (122) so that the cleaning member (122) can be fitted thereto.

[0270]

[0271] The cleaning member (122) is configured to clean the mop of the robot cleaner (200), and the cleaning member (122) can be mounted on the cleaning member connecting portion (121e) of the floor member (121).

[0272] A protrusion (122a) and a drain hole (122b) may be formed on the cleaning member (122). When the mop (242) of the robot cleaner (200) is mounted on the cleaning member (122) and the driving unit of the rotating cleaning unit (240) is driven, the mop (242) rotates. At this time, when the mop (242) rotates while washing water is supplied to the cleaning member, the mop (242) can be washed by rubbing against the protrusion (122a) that is in a stationary state.

[0273] In addition, the cleaning member (122) may be formed to slope downward toward the center. Accordingly, the cleaning water flowing along the inclined cleaning member (122) can, after washing the mop (242), drain into the space formed between the cleaning member (122) and the cleaning member joining portion (121e) through the drain hole (122b).

[0274] 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 coupling unit (120). At this time, the receiving space (S) can be placed inside the coupling unit (120).

[0275] The dust collection unit (140) may include a dust collection unit housing (141), a dust bag (not shown), a filter (142), and a dust collection unit drawer (144).

[0276] The dust collection unit housing (141) can form a space inside which a dust bag (not shown), a filter (142), and a dust collection unit drawer (144) can be accommodated.

[0277] The dust collection housing (141) is connected to a dust collection drawer (144) so ​​that a dust collection bag (not shown) can be stored inside the dust collection 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 flow path (131) and the second flow path (132).

[0278] One side of the inside of the dust collector housing (141) can be communicated with the first flow path (131), and the other side can be communicated with the second flow path (132). In addition, when a dust bag (not shown) is combined with the dust collector housing (141), the dust bag (not shown) can be communicated with the first flow path (131) inside the dust collector housing (141).

[0279] 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 (152). 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). That is, the dust bag (not shown) may be defined as a consumable part.

[0280] The dust bag (not shown) may be provided so that when suction power is generated by the dust collection motor (152), its volume increases and dust is accommodated inside.

[0281] 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.

[0282] Alternatively, the dust bag (not shown) may be formed of an impermeable material. For example, the dust bag (not shown) may include a roll of vinyl (not shown). With this configuration, when the dust bag (not shown) is sealed or bonded, dust or odors captured inside the dust bag (not shown) can be prevented from leaking out of the dust bag (not shown). At this time, the dust bag (not shown) may be mounted on the dust collection unit housing (141) via a dust bag cartridge (not shown). If necessary, the dust bag (not shown) may be replaced via the dust bag cartridge.

[0283] A filter (142) may be placed between the dust collection housing (141) and the second passage (132). 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 passage (132) through the filter (142).

[0284] A filter (142) may be placed between the dust collection housing (141) and the second passage (132). 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 passage (132) through the filter (142).

[0285] The dust collection drawer (144) is connected to the dust collection housing (141) so that it can be withdrawn, and a dust bag (not shown) can be accommodated inside.

[0286] At this time, referring to FIG. 26, the dust collection drawer (144) includes a dust collection drawer body (144a), a handle (144d), and a drawer rail (144e).

[0287] The dust collection drawer body (144a) may provide a space where a dust bag (not shown) can be combined inside. For example, the dust collection 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 flow path (131) and the second flow path (132).

[0288] For example, the dust collection 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 collection drawer body (144a) may be formed so that it is larger than the lower left-right width. That is, the interior of the dust collection 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.

[0289] The upper side of the dust collection drawer body (144a) can be connected to the first flow path (131) through the inlet (144b). The inlet (144b) may be configured to guide air flowing through the first flow path (131) into the interior of a dust bag (not shown). The inlet (144b) can connect the first flow path (131) 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 flow path (131) and the inlet (144b).

[0290] The dust collection drawer (144) can be connected to the second flow path (132) through an outlet (144c) formed on the lower side. The outlet (144c) may be configured to guide air passing through the dust collection drawer (144) to the second flow path (132). 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 collection drawer (144) and the second flow path (132). Therefore, air filtered of dust while passing through the dust bag (not shown) can move to the second flow path (132) through the outlet (144c).

[0291] A handle (144d) may be provided at the front of the dust collection 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 collection drawer body (144a), and a grip portion formed by connecting the pair of connecting portions so that a user can grip it.

[0292] With this configuration, when a user holds the handle and pulls it forward, the dust collection drawer body (144a) can be pulled forward and withdrawn as well. Therefore, according to the present invention, a user can easily pull the dust collection drawer (144) forward, and then lift the dust bag (not shown) upward to remove and replace it.

[0293] A drawer rail (144e) may be formed on the left and right sides of the dust collection drawer body (144a). The drawer rail (144e) may guide the movement of the dust collection drawer body (144a).

[0294] For example, the drawer rail (144e) may be formed in the shape of a groove or rib along the front-back direction on the left and right sides of the dust collection drawer body (144a).

[0295] With this configuration, when the user couples the dust collector drawer (144) to the dust collector housing (141), it can be coupled in the correct position, and the dust collector (140) and the first flow path (131) and the second flow path (132) can be connected in the correct position to reduce flow loss.

[0296] 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.

[0297]

[0298] FIG. 12 is a side view illustrating a dust collection path of a robot cleaner station according to an embodiment of the present invention, FIGS. 13 to 16 are cross-sectional views illustrating a dust collection path of a robot cleaner station according to an embodiment of the present invention, and FIG. 17 is a cross-sectional view illustrating a discharge hole of a dust collection motor housing of a robot cleaner station according to an embodiment of the present invention.

[0299] Referring to FIGS. 12 to 17, the dust collection path (130) is described as follows.

[0300] The robot cleaner station (100) may include a dust collection path (130). The dust collection path (130) may refer to a path through which air sucked in through the dust passage hole (123a) flows through the dust collection unit (140) to the dust collection motor (152).

[0301] Specifically, the dust collection path (130) may include a first path (131) that connects the dust bin (220) and the dust collection unit (140) 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, and a second path (132) that connects the dust collection unit (140) and the dust collection motor (152).

[0302] Meanwhile, in this specification, the first flow path (131) may also be referred to as a suction flow path (131). Hereinafter, for convenience of explanation, both the first flow path (131) and the suction flow path (131) will be referred to as the first flow path (131).

[0303] The first flow path (131) can connect the dust bin (220) and the dust collection unit (140) of the robot cleaner (200). The first flow path (131) can connect the dust bin (220) and the dust collection unit (140) of the robot cleaner (200). The first flow path (131) can connect the dust passage hole (123a) of the coupling part (120) and the dust collection unit (140). The first flow path (131) can mean a space between the dust bin (220) and the dust collection unit (140) of the robot cleaner (200). The first flow path (131) can be formed close to the horizontal direction. The first flow path (131) can be a space formed toward the rear from the dust passage hole (123a), and can be a flow path formed by bending toward the side from the dust passage hole (123a) so that dust and air can flow. Dust in the dust bin (220) of the robot vacuum cleaner (200) can move to the dust collection unit (140) through the first euro (131).

[0304] The second flow path (132) can connect the dust collection unit (140) and the dust collection motor (152). The second flow path (132) can be formed in a nearly horizontal direction. At this time, the first flow path (132) and the second flow path (131) can be formed at different heights. The first flow path (131) and the second flow path (132) can be formed in a stacked structure. The second flow path (132) can be arranged lower than the first flow path (131). With this configuration, the left-right width and the overall volume of the robot cleaner station (100) can be minimized.

[0305] The dust collection module (150) can provide suction airflow to the dust collection path (130).

[0306] Specifically, the dust collection module (150) may include a dust collection motor housing (151) and a dust collection motor (152).

[0307] The dust collecting motor housing (151) can be placed inside the housing (110). The dust collecting motor housing (151) can accommodate a dust collecting motor (152) inside.

[0308] An inlet hole (151a) and an outlet hole (151b) may be formed in the dust collecting motor housing (151).

[0309] The internal space of the dust collecting motor housing (151) can be communicated with the second flow path (132) through the inlet hole (151a). Therefore, the inlet hole (151a) can guide the air flowing through the second flow path (132) to the dust collecting motor (152).

[0310] The internal space of the dust collecting motor housing (151) can be communicated with the circulation path (125a) through the discharge hole (151b). Therefore, the discharge hole (151b) can guide the air passing through the dust collecting motor (152) to the circulation path (125a).

[0311] The dust collecting motor (152) can generate suction force in the dust collecting passage (130). The dust collecting motor (152) can be placed inside the dust collecting motor housing (151).

[0312] The dust collecting motor (152) may be placed at the rear of the dust collecting unit (140). Through this, the dust collecting motor (152) may provide suction power capable of sucking up dust inside the dust bin (220) of the robot cleaner (200).

[0313] The dust collecting motor (152) can generate suction force by rotation. For example, the dust collecting motor (152) can be formed in a shape similar to a cylinder.

[0314] The dust collecting motor (152) may have one side connected to the second flow path (132) and the other side connected to the circulation flow path (125a). When the dust collecting motor (152) is driven, air flowing through the second flow path (132) may be introduced into the dust collecting motor housing (151) through the inlet hole (151a). In addition, the air introduced into the interior of the dust collecting motor housing (151) may be exhausted through the exhaust hole (151b) after passing through the dust collecting motor (152). In addition, the air exhausted through the exhaust hole (151b) may flow through the circulation flow path (125a) and be exhausted to the exhaust port (125b).

[0315] Meanwhile, the rotation axis of the dust collecting motor (152) may be formed to be close to the horizontal direction. In addition, the inlet hole (151a) and the discharge hole (151b) of the dust collecting motor housing (151) may also be opened in the horizontal direction. In addition, the discharge hole (151b) may be positioned at the same height as the exhaust port (125b). 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.

[0316] The exhaust unit (125) can guide air discharged from the dust collecting motor (152) to the outside of the housing (110). The exhaust unit (125) can connect the internal space and the external space of the housing (110).

[0317] The exhaust section (125) may be composed of a circulation path (125a) and an exhaust port (125b).

[0318] The circulation path (125a) can provide a path through which air discharged from the dust collecting motor (152) flows. The circulation path (125a) can be arranged inside the bottom member body (121a).

[0319] The circulation path (125a) may be connected to the dust collecting motor (152) in a flow path manner. The circulation path (125a) may refer to a flow path connecting the discharge hole (151b) and the exhaust port (125b). One end of the circulation path (125a) may be connected to the internal space of the dust collecting motor housing (151), and the other end of the circulation path (125a) may be connected to the receiving space (121dc) of the recessed portion (121da). Specifically, one end of the circulation path (125a) may be connected to the discharge hole (151b), and the other end of the circulation path (125a) may be connected to the exhaust port (125b).

[0320] The circulation path (125a) may be a path formed horizontally within the housing (110). The circulation path (125a) may be connected to the dust collecting motor (152) in a flow direction. Specifically, one end of the circulation path (125a) may be connected to the dust collecting unit (140), and the other end of the circulation path (125a) may be connected to the exhaust port (125b).

[0321] The exhaust port (125b) can serve as an outlet that guides air discharged from the dust collecting motor (152) to the receiving space (121dc) of the recessed portion (121da). Accordingly, air discharged from the dust collecting motor (152) and flowing through the circulation path (125a) can be discharged to the outside of the housing (110) through the exhaust port (125b).

[0322] The exhaust port (125b) may be formed in the bottom member (121). The exhaust port (125b) may be formed in the agitator receiving portion (121d). The exhaust port (125b) may be formed in the recessed portion (121da) of the agitator receiving portion (121d). The exhaust port (125b) may be formed on the side of the recessed portion (121da).

[0324] FIGS. 18 to 20 are drawings illustrating a circulation path of a robot cleaner station according to an embodiment of the present invention, FIGS. 21 and 22 are drawings illustrating a state in which a portion of the bottom surface of a floor member body is removed to illustrate a circulation path of a robot cleaner station according to an embodiment of the present invention, and FIG. 23 is a perspective view illustrating area A illustrated in FIG. 22 in detail.

[0325] The circulation path of the robot cleaner station according to the embodiment of the present invention will be described with reference to FIGS. 18 to 23 as follows.

[0326] The circulation path (125a) according to the embodiment of the present invention can guide the air discharged from the dust collecting motor (152) to the suction part (211) of the robot cleaner (200).

[0327] The circulation path (125a) can create a structure in which the air discharged from the dust collecting motor (152) 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 (152) is not discharged to the installation space (24) of the kitchen cabinet (2), but is reintroduced into the interior of the robot cleaner (200) to form a circulation path, thereby having the effect of preventing the interior of the kitchen cabinet (2) from being damaged.

[0328] The circulation path (125a) may refer to a space between the exhaust port (125b) of the robot cleaner station (100) and the suction port (211) of the robot cleaner (200). The circulation path (125a) may refer to a recessed portion (121da) of the agitator receiving portion (121d). The circulation path (125a) may refer to a connecting pipe (not shown) that is connected to the suction port (211) of the robot cleaner (200) and has the other end connected to the exhaust port (125b) of the robot cleaner station (100).

[0329] The air passing through the dust collecting motor (152) is discharged to the receiving space (S) through the exhaust port (125b), and the air discharged to the receiving space (S) can be re-introduced to the suction unit (211) due to the suction force of the dust collecting motor (152). Therefore, the air sucked in from the dust bin (220) by the suction force of the dust collecting motor (152) can flow sequentially through the dust passage hole (123a), the first flow path (131), the dust collecting unit (140), the second flow path (132), the dust collecting motor (152), the circulation flow path (125a), and the exhaust port (125b), and then be discharged to the receiving space (S).

[0330] When the dust collector motor (152) is driven while the dust bin (220) of the robot cleaner (200) and the suction unit (211) of the robot cleaner station (100) are connected, air can be sucked in through the suction unit (211) of the robot cleaner (200). In addition, since the suction unit (211) houses an agitator (250), air discharged from the dust collector motor (152) and exhausted through the exhaust port (125b) can be sucked into the suction unit (211) of the robot cleaner (200) by the suction force of the dust collector motor (152).

[0331] At this time, the dust collection motor (152) can be driven together with the suction motor (not shown) of the robot cleaner (200). The air exhausted through the exhaust port (125b) is sucked into the suction part (211) by the suction power of the suction motor (not shown) in addition to the dust collection motor (152), thereby improving the dust collection efficiency.

[0333] FIG. 24 is an enlarged view illustrating a mop washing unit of a robot cleaner station according to an embodiment of the present invention, FIG. 25 is an enlarged view illustrating a washing water discharge unit of a mop washing unit of a robot cleaner station according to an embodiment of the present invention, FIG. 26 is a drawing illustrating a structure of a detergent container (163) in a robot cleaner station according to an embodiment of the present invention, and FIG. 27 is a cross-sectional perspective view illustrating a space formed between a cleaning member and a cleaning member coupling unit of a robot cleaner station according to an embodiment of the present invention.

[0334] Referring to FIGS. 24 to 26, the mop washing unit (160) of the robot cleaner station (100) according to an embodiment of the present invention will be described as follows.

[0335] 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 coupling unit (120).

[0336] The mop washing unit (160) may include a washing water discharge unit (161) that discharges washing water to the washing member (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).

[0337] In the washing water discharge unit (161), purified water and detergent can be mixed to generate washing water for washing the mop (242).

[0338] A pair of washing water discharge units (161) may be spaced apart from each other on the rear side of the joining wall (123). The washing water discharge units (161) may discharge washing water toward the washing member (122) from the upper sides of both ends of the washing member (122). At this time, purified water supplied from the water supply pipe (160a) of the kitchen cabinet (2) and passing through the regulator (162) may be branched to both sides through the branch flow path (161a) and connected to each of the washing water discharge units (161) spaced apart from each other. That is, the branch flow path (161a) may be formed in the form of one pipe branching into two, and at this time, one of the branched ends may be connected to one of the pair of washing water discharge units (161), and the other of the branched ends may be connected to the other of the pair of washing water discharge units (161).

[0339] The washing water discharge unit (161) 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).

[0340] A water purification inlet (161b), a detergent inlet (161c), and a water purification outlet (not shown) may be formed in the washing water discharge portion (161).

[0341] The purified water inlet (161b) is configured to guide purified water supplied from the water supply pipe (160a) of the kitchen cabinet (2) to the washing water discharge unit (161). Specifically, the water supply pipe (160a) of the kitchen cabinet (2) is connected to a regulator (162) so that the flow rate supplied from the water supply pipe (160a) 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 discharge units (161) that are spaced apart from each other through the purified water inlet (161b).

[0342] The detergent inlet (161c) is configured to guide liquid containing detergent supplied from the detergent container (163) to the washing water discharge unit (161). Specifically, liquid containing detergent stored in the detergent container (163) can be supplied to the washing water discharge unit (161) via a pump (not shown).

[0343] In addition, the detergent and purified water introduced into the washing water discharge unit (161) can be mixed and used as washing water. The washing water discharge unit (161) can discharge the washing water to the upper surface of the washing member (122) through the washing water discharge port. The washing water discharge port can be formed on the lower surface of the washing water discharge unit (161). The washing water discharge port can be opened in a direction facing the upper surface of the mop (242) mounted on the washing member (122).

[0344] The detergent container (163) can store liquids including detergent.

[0345] The detergent container (163) includes a detergent container body (163a), a handle (163b), and a detergent container rail (163c).

[0346] The detergent container body (163a) can provide a space for storing liquid including detergent. For example, the detergent container body (163a) can be formed in a box shape with an open top, and the rear can be connected to a washing water discharge unit (161).

[0347] 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.

[0348] 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.

[0349] 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).

[0350] 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).

[0351] 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.

[0352] 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).

[0353] The wastewater tank (164) can provide a space for storing the washing water used to wash the mop (242). The washing water discharged from the upper surface of the washing member (122) can be drained into the drain hole (122b) while descending along the slope of the washing member (122) after washing the mop (242). The washing water passing through the drain hole (122b) accumulates between the washing member coupling portion (121e) and the washing member (122). In addition, the washing water accumulated between the washing member coupling portion (121e) and the washing member (122) can be introduced into the wastewater tank (164) through the pump passage (164b).

[0354] Washing water stored in the wastewater tank (164) can be drained to the drain pipe (25) of the kitchen cabinet (2) through the drainage channel (164a). One end of the drainage channel (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 drainage channel (164a) by a centrifugal pump (not shown).

[0355] The drainage 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 drainage 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 drainage path (164a).

[0356] 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 drain passage (164a). The check valve may be provided at the other end of the drain passage (164a) connected to the drain pipe (25).

[0357] Meanwhile, the detergent container (163) and the waste container (164) can be accommodated in the space formed between the side 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 side 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 side wall (124) and the outer wall (111) of the housing.

[0359] FIG. 28 is a perspective view illustrating a mop drying unit of a robot cleaner station according to one embodiment of the present invention, FIGS. 29 and 30 are enlarged views illustrating a mop drying unit of a robot cleaner station according to one embodiment of the present invention, and FIG. 31 is a cross-sectional view illustrating air flowing into a heat supply module according to one embodiment of the present invention.

[0360] Referring to FIGS. 28 to 31, 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.

[0361] The mop drying unit (170) according to the first embodiment of the present invention may include a heat supply module (171), a steam discharge pipe (172), an exhaust fan (173), and a check valve (not shown).

[0362] The heat supply module (171) can supply heat to the receiving space (S) and may include a connection path (171a), a blower fan (not shown), and a heater (171d).

[0363] The connecting passage (171a) can connect the external space of the housing (110) and the receiving space (S). The air inlet (171b) of the connecting passage (171a) can be communicated with the external space, and the air outlet (171c) of the connecting passage (171a) can be communicated with the receiving space (S).

[0364] The air inlet (171b) of the connecting urea (171a) can be formed on the rear side of the housing (110).

[0365] The air outlet (171c) of the connecting member (171a) may be positioned on the upper side of the cleaning member (122). The air outlet (171c) may be opened in a direction facing the cleaning member (122). A pair of air outlets (171c) may be provided, with the air outlets (171c) being opened downward.

[0366] The air exhaust port (171c) can be opened toward the upper side of the mop (242) when the mop (242) is mounted on the cleaning member (122). The air exhaust port (171c) can be positioned adjacent to the mop (242) when the mop (242) is mounted on the cleaning member (122), and can be opened downward so that the exhausted air can flow toward the mop (242). The air exhaust port (171c) can be opened in a direction facing the mop (242) when the robot cleaner (200) is mounted on the coupling part (120).

[0367] A blower fan (not shown) is placed on the connecting passage (171a) and can blow air toward the receiving space (S). When the blower fan (not shown) is driven, air drawn in through the air inlet (171b) can be heated by the heater (171d) and discharged into the receiving space (S) through the air outlet (171c).

[0368] The heater (171d) is arranged on the connecting passage (171a) and can heat the air flowing through the connecting passage (171a). The heater (171d) can heat the air discharged through the air outlet (171c). The heater (171d) may be arranged on the connecting passage (171a), but may alternatively be arranged on the air outlet (171c). That is, as long as it can heat the air discharged into the receiving space (S), there are no restrictions on the specific shape or arrangement.

[0369] The heater (171d) may include a heater housing (171da) and a heating element (not shown). The heater housing (110) may be placed on a connecting passage (171a), and a space may be provided therein in which the heater (171d) may be accommodated. The heating element may heat external air flowing into the heater housing (110). Accordingly, the air heated by the heating element may be discharged into the accommodation space (S) through the air outlet (171c) to dry the wet mop (242).

[0370] The steam exhaust pipe (172) can discharge the hot and humid air in the receiving space (S) generated while drying the mop (242) to the drain pipe (25). The steam exhaust pipe (172) can connect the receiving space (S) and the drain pipe (25) of the kitchen cabinet (2).

[0371] One end of the steam discharge pipe (172) can be connected to the receiving space (S), and the other end can be connected to the drain pipe (25). Specifically, one end of the steam discharge pipe (172), which is an air inlet (172a), can be connected to the receiving space (S), and the other end, which is an air discharge port (not shown), can be connected to the drain pipe (25).

[0372] The steam discharge pipe (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 steam discharge pipe (172) is connected upstream (25b) with respect to the oil trap (25a) of the drain pipe (25), the heat exhausted through the steam discharge pipe (172) may not pass through the drain pipe (25) due to water accumulated in the oil trap (25a).

[0373] Meanwhile, the steam discharge pipe (172) 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 steam discharge pipe (172) penetrating the outer walls (111) on both sides of the housing (110) may be connected to a drain pipe (25). Therefore, the steam in the receiving space (S) sucked in through the steam discharge pipe (172) may flow through the steam discharge pipe (172) branched to both sides and be exhausted downstream (25c) based on the oil trap (25a) of the drain pipe (25).

[0374] The exhaust fan (173) can exhaust air from the receiving space (S) to the drain pipe (25) through the steam discharge pipe (172). The exhaust fan (173) can cause air to flow along the steam discharge pipe (172). The exhaust fan (173) can be placed on the steam discharge pipe (172).

[0375] When the exhaust fan (173) is driven, air in the receiving space (S) can be introduced into the air inlet (172a). The air introduced into the air inlet (172a) can flow through the steam discharge pipe (172) and be exhausted to the drain pipe (25). Specifically, when the exhaust fan (173) is driven, the air flowing through the steam discharge pipe (172) can be exhausted downstream (25c) based on the oil trap (25a) of the drain pipe (25).

[0376] The mop drying unit (170) may include a check valve (not shown). The check valve may prevent the fluid inside the drain pipe (25) from flowing back into the steam discharge pipe (172). The check valve may be provided at the other end of the steam discharge pipe (172) connected to the drain pipe (25).

[0377]

[0378] FIG. 32 is a front view illustrating the arrangement relationship on a horizontal plane of a robot cleaner station according to an embodiment of the present invention, and FIG. 33 is a side view of FIG. 32.

[0379] The arrangement of the robot cleaner station (100) according to an embodiment of the present invention will be described with reference to FIGS. 4, 32, and 33 as follows.

[0380] 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).

[0381] 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.

[0382] Specifically, in the robot cleaner station (100) according to the embodiment of the present invention, the dust collection unit (140) and / or the mop washing unit (160) can be placed on the side of the entrance (127).

[0383] At this time, if both a dust collection unit (140) and a mop washing unit (160) are provided, the coupling unit (120) can be placed between the dust collection unit (140) and the mop washing unit (160).

[0384] For example, an entrance (127) and a door (126) may be arranged at the front of the robot cleaner station (100). In addition, a coupling part (120) to which a robot cleaner (200) is coupled may be arranged rearward from the entrance (127). At this time, a dust collection part (140) may be arranged rearward by a predetermined length from the front end of the robot cleaner station (100). In addition, a mop washing part (160) may also be arranged rearward by a predetermined length from the front end of the robot cleaner station (100).

[0385] 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).

[0386] 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.

[0387] 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.

[0388] 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.

[0389] Meanwhile, the rear ends of the dust collection unit (140) and the mop washing unit (160) may be positioned at a predetermined distance from the rear end of the housing (110). In addition, a dust collection motor (152) may be positioned between the rear end of the housing (110) and the rear end of the dust collection unit (140). With this configuration, the connection of a wire supplying power to the dust collection motor (152) may be facilitated. In addition, there is an effect of minimizing the total space occupied by the coupling unit (120), the dust collection unit (140), and the dust collection motor (152) within a limited space.

[0390] 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 mop washing unit (160). With this configuration, the path for washing water to flow from the water supply pipe (160a) can be minimized. In addition, there is an effect of minimizing the total space occupied by the connecting portion (120), the mop washing unit (160), and the flow path for washing water to flow within a limited space.

[0391]

[0392] Meanwhile, the robot cleaner station (100) may have a mop drying unit (170) positioned rearward of the coupling unit (120). At this time, the mop drying unit (170) may be positioned between the rear end of the coupling unit (120) and the rear end of the housing (110).

[0393] 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 based on the coupling unit (120), and a mop drying unit (170) arranged on the rear side.

[0394] 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 coupling unit (120).

[0395] Through this arrangement, there is an effect in which the joint part (120), dust collection part (140), mop washing part (160), and mop drying part (170) can all be arranged in the narrowest space on the horizontal plane.

[0396] 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).

[0397] In addition, by this arrangement, the robot cleaner station (100) of the present invention can place all components within a limited height.

[0398] Specifically, based on the state in which the robot cleaner (200) is coupled to the coupling unit (120), at least a portion of the dust collection unit (140) may be positioned lower than the top of the robot cleaner (200). In addition, at least a portion of the mop washing unit (160) may be positioned lower than the top of the robot cleaner (200). In addition, at least a portion of the mop drying unit (170) may be positioned lower than the top of the robot cleaner (200). In addition, at least a portion of the mop washing unit (160) may be positioned lower than the top of the dust collection unit (140).

[0399] In addition, based on the state in which the robot cleaner (200) is coupled to the coupling part (120), the top of the robot cleaner (200) may be positioned higher than the dust bag (not shown). 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 (not shown) may be positioned higher than the detergent container (163).

[0400] From another perspective, when a virtual plane (H) parallel to the kitchen floor is drawn with the robot cleaner (200) connected to the connecting part (120), the plane (H) can pass through the robot cleaner (200), the dust collection part (140), the mop washing part (160), and the mop drying part (170). This means that all components can be placed within a certain height range.

[0401] From another perspective, when the robot cleaner (200) is coupled to the coupling part (120), the coupling part (120) may be divided into three regions in the vertical direction. At this time, the coupling part (120) may include a first region (space between B and H1) located on the same horizontal space as the detergent container (163), a second region (space between H1 and H2) located above the first region but on the same horizontal space as at least a portion of the dust bag (not shown), and a third region (space between H2 and H3) located above the second region. At this time, both the dust bag (not shown) and the detergent container (163) may be arranged on both left and right sides of the first region, a dust bag (not shown) and a waste container (164) may be arranged on both left and right sides of the second region, and only the upper part of the robot cleaner (200) may be arranged in the third region.

[0402] 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 coupling unit (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).

[0403]

[0404] Meanwhile, if the charging base for the robot cleaner is placed under the kitchen cabinet, it can provide an interior effect by minimizing exposure to the outside. However, if the robot cleaner breaks down while it is placed under the kitchen cabinet, or if the charging base for the robot cleaner breaks down, it may be difficult for the user to take it out and repair it. To solve this problem, the present invention may add a drawer (190) to the robot cleaner station (100).

[0405]

[0406] FIG. 34 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. 35 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.

[0407] Referring to FIGS. 34 and 35, the drawer (190) of the robot cleaner station (100) according to one embodiment of the present invention will be described as follows.

[0408] 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).

[0409] When the drawer (190) is inserted into the housing (110), the door (126) can be closed when the robot cleaner (200) enters the coupling part (120). In this case, the inside and outside of the housing (110) of the robot cleaner (200) can be blocked by the door (126).

[0410] 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).

[0411] 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).

[0412] At this time, the drawer (190) can be withdrawn with the coupling part (120) provided inside. With this configuration, when the drawer (190) is withdrawn, the coupling part (120) and / or the robot cleaner (200) can be withdrawn outside the kitchen cabinet (2).

[0413] 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 joint (120) may be exposed to the outside.

[0414] 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 coupling part (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).

[0415] 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).

[0416] 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 collection unit drawer (144) can be parallel to the pulling out direction of the drawer (190).

[0417] 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).

[0418] On the other hand, the sewage tank (164) of the present invention can be withdrawn from the housing (110) separately from the drawer (190). At this time, the direction in which the sewage tank (164) is withdrawn can be parallel to the direction in which the drawer (190) is withdrawn.

[0419] 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 waste tank (164) having the withdrawal directions all parallel.

[0420] 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.

[0421]

[0422] The drawer (190) includes a drawer side wall (191), a fitting portion (192), and a drawer rail (193).

[0423] 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 walls (111) of a pair of housings (110).

[0424] Meanwhile, in the present invention, the height of the upper end of the drawer side wall (191) is higher than the height of the upper end of the outer wall (111). That is, a height difference may occur between the upper end of the drawer side wall (191) and the upper end of the outer wall (111). Through this height difference, a space in which the fitting part (192) described later can move can be provided.

[0425] At this time, a pair of drawer side walls (191) may be arranged closer to the inner side of the robot cleaner station (100) than the outer walls (111) of the pair of housings (110). That is, a pair of drawer side walls (191) may be arranged closer to the joint (120) than the outer walls (111) of the pair of housings (110). At this time, a pair of drawer side walls (191) may be arranged to have a gap greater than the maximum horizontal width of the robot cleaner (200).

[0426] At this time, a pair of drawer side walls (191) may be directly connected to the bottom member (121) of the joint (120). Alternatively, a pair of drawer side walls (191) may be connected by a drawer base (not shown), and the joint (120) may be connected to the upper side of the drawer base (not shown) and moved together.

[0427] Meanwhile, a dust collection unit (140) and / or a mop washing unit (160) may be placed between the drawer side wall (191) and the coupling unit (120). That is, based on the state in which the robot cleaner (200) is coupled to the coupling unit (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).

[0428] 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.

[0429]

[0430] 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.

[0431] 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).

[0432] The fitting part (192) is detachably connected to at least one of the hose and the wire.

[0433] At this time, in terms of height, the fitting part (192) may be placed between the upper part of the drawer side wall (191) and the upper part of the outer wall (111). In addition, the fitting part (192) may be placed between the upper part of the front supporter (112) and the upper part of the outer wall (111).

[0434] With this configuration, the fitting part (192) moves together with the drawer side wall (191) during the process of withdrawing the drawer (190), and since the fitting part (192) moves in a straight line above the upper side of the outer wall (111) during the process of withdrawing the drawer (190), the fitting part (192) can be prevented from interfering with the outer wall (111).

[0435] However, the fitting part (192) may be positioned lower than the height of the top of the front supporter (112). That is, in terms of height, the fitting part (192) may be positioned between the top of the front supporter (112) and the top of the outer wall (111).

[0436] This is because the top of the front supporter (112) must be at a height that can come into contact with the lower plate (23) of the kitchen cabinet (2).

[0437] Accordingly, when the front supporter (112) is placed in front of the outer wall (111), the front supporter (112) is placed on the movement path of the fitting part (192) when the drawer (190) is pulled out, and the fitting part (192) may interfere with the front supporter (112).

[0438] To solve this, the front supporter (112) of the present invention is hinge-joined to the outer wall (111), so that when the front supporter (112) is rotated, it moves to the outside of the outer wall (111), and interference between the fitting part (192) and the drawer (190) can be avoided.

[0439] Therefore, in the present invention, the worker can rotate the front supporter (112) positioned in front of the outer wall (111) and then withdraw the fitting part (192).

[0440] Meanwhile, the robot cleaner station (100) of the present invention may have a predetermined gap between the outer surface of the drawer side wall (191) and the outer wall cover (111a). In addition, when the front supporter (112) is rotated toward the outside of the outer wall (111), a space having a predetermined gap may be formed between the drawer side wall (191) and the front supporter (112). At this time, it is preferable that the gap be larger than the diameter of a human finger.

[0441] With this configuration, when the worker pulls the drawer (190) so that the fitting portion (192) is pulled close to the front supporter (112), the worker can rotate the front supporter (112) and insert his / her finger into the space between the drawer side wall (191) and the front supporter (112) to detach one or more hoses and / or wires connected to the fitting portion (192). Thereafter, when the worker further pulls the drawer (190), the entire drawer (190) can be completely withdrawn from the housing (110).

[0442] Therefore, according to the present invention, the worker can simply completely withdraw the drawer (190) from the housing (110) without disassembling the mop holder of the kitchen cabinet (2).

[0443] 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.

[0444]

[0445] FIG. 36 is a drawing for explaining a rear supporter in a robot cleaner station according to an embodiment of the present invention, and FIG. 37 is a drawing for explaining an operating principle of a rear supporter in a robot cleaner station according to an embodiment of the present invention.

[0446] Referring to FIGS. 36 and 37, a rear supporter according to one embodiment of the present invention is described as follows.

[0447] According to one embodiment of the present invention, rear supporters (114, 115) are respectively provided on a pair of outer walls (111) and are provided to support a kitchen cabinet (2). At this time, the rear supporters (114, 115) are configured to be in contact with and support the lower plate (23) of the kitchen cabinet (2), and it is also possible to include a first rear supporter (114) that is in contact with and supported by the kitchen cabinet (2) and a second rear supporter (115) that is in contact with and supported by the kitchen floor to maintain overall balance according to the floor condition of the kitchen.

[0448] Meanwhile, the first rear supporter (114) and the second rear supporter (115) are arranged symmetrically with each other, but their structure and operation method are the same.

[0449] The rear supporter (114, 115) includes a rear support portion (114a, 115a), a helical gear portion (114b, 115b), a worm gear portion (114c, 115c), and a head portion (114d, 115d).

[0450] At this time, the rear support portion (114a, 115a) is coupled to the helical gear portion (114b, 115b) so as to be relatively movable, the helical gear portion (114b, 115b) and the worm gear portion (114c, 115c) are meshed, and the worm gear portion (114c, 115c) and the head portion (114d, 115d) are connected to each other.

[0451] The rear support members (114a, 115a) support the kitchen cabinet (2) and the kitchen floor by moving up and down. Specifically, the rear support member (114a) of the first rear supporter (114) is provided to be able to move up and down from the outer wall (111) so as to contact and support the lower plate (23) of the kitchen cabinet (2), and the rear support member (115a) of the second rear supporter (115) is provided to be able to move up and down from the outer wall (111) so as to contact and support the kitchen floor.

[0452] The rear support member (114a, 115a) is formed in a shape similar to a bolt as a whole, but the head part that comes into contact with the kitchen cabinet (2) or the floor of the kitchen may be in the shape of a disc or in the shape of a disc with slits formed at a predetermined interval along the circumference.

[0453] That is, the rear support portion (114a, 115a) may be formed of a screw-shaped column portion and a head portion having a larger diameter than the column portion. In this case, the head portion may be formed radially to disperse an external force applied from the support object.

[0454] With this configuration, the rear support member (114a, 115a) can adjust its height by moving the column part up or down along the screw thread when the helical gear member (114b, 115b) rotates.

[0455] The helical gear portion (114b, 115b) meshes with the worm gear portion (114c, 115c) and can be combined with the rear support portion (114a, 115a).

[0456] The helical gear portion (114b, 115b) can transmit the rotational force applied from the worm gear portion (114c, 115c) to the rear support portion (114a, 115a).

[0457] For example, the helical gear portion (114b, 115b) may be formed in a ring shape, with a helical gear formed on the outer circumferential surface and a screw thread formed on the inner circumferential surface.

[0458] Meanwhile, at least a portion of the helical gear portion (114b, 115b) may be rotatably accommodated in the supporter installation portion (111c). That is, the supporter installation portion (111c) may be formed to protrude from the wall portion (111b) so as to block at least a portion of the vertical movement of the helical gear portion (114b, 115b). Accordingly, the helical gear portion (114b, 115b) may be rotated in place while its vertical movement is restricted.

[0459] Accordingly, the helical gear portions (114b, 115b) mesh with the worm gear portions (114c, 115c) and rotate in place according to the rotation of the worm gear portions (114c, 115c), and the screw threads of the rear support portions (114a, 115a) move along the screw threads of the helical gear portions (114b, 115b), so that the rear support portions (114a, 115a) can be moved up or down.

[0460] The worm gear portion (114c, 115c) is connected to the head portion (114d, 115d) and rotates together, and can rotate the helical gear portion (114b, 115b).

[0461] Specifically, the worm gear portion (114c, 115c) is formed in a cylindrical shape, and a worm gear can be formed on the outer surface thereof. One end in the longitudinal direction (axial direction) is connected to the head portion (114d, 115d), and the other end in the longitudinal direction is rotatably coupled to the supporter installation portion (111c).

[0462] With this configuration, the operating force applied from the head (114d, 115d) can be transmitted to the helical gear portion (114b, 115b).

[0463] The head (114d, 115d) can be combined with a work tool to receive the operator's operating power.

[0464] For example, the head portion (114d, 115d) is formed in the shape of a circular rod, and one longitudinal end is provided so as to be connectable with a work tool, and the other longitudinal end can be connected to a worm gear portion (114c, 115c).

[0465] At this time, one end of the head (114d, 115d) may be formed in a shape similar to the head of a screw. That is, one end of the head (114d, 115d) may be formed so that a tool such as a flat-head screwdriver or a cross-head screwdriver can be inserted therein to apply rotational force.

[0466] Meanwhile, when the front supporter (112) is positioned in front of the outer wall (111), the extension of the rotation axis (longitudinal direction) of the head (114d, 115d) can pass through the operation hole (112e). Through this, the worker can operate the height of the rear supporter using a work tool at the front of the robot cleaner station.

[0467] Therefore, according to the present invention, the head portion (114d, 115d) and the worm gear portion (114c, 115c) can be rotated by the operating force of the work tool.

[0468]

[0469] Accordingly, the process of adjusting the height of the robot cleaner station (100) or fixing it to a kitchen cabinet (2) by operating the rear supporter (114, 115) of the robot cleaner station (100) according to the present invention is described as follows.

[0470] The worker inserts a work tool, such as a driver, into the operating hole (112e) formed at the front of the front supporter (112). At this time, the worker can select whether to operate the first rear supporter (114) or the second rear supporter (115), and insert the work tool into the upper operating hole (112e) or the lower operating hole (112e).

[0471] Next, when the worker pushes the work tool further in the horizontal direction, the end of the work tool can be fitted into the head (114d, 115d).

[0472] Next, the worker can rotate the head (114d, 115d) by turning the work tool. Accordingly, the head (114d, 115d) and the worm gear (114c, 115c) rotate together, and the helical gear (114b, 115b) rotates in conjunction with the rotation of the worm gear (114c, 115c).

[0473] As a result, the rear support member (114a, 115a) can be raised or lowered along the screw thread formed on the inner surface of the helical gear member (114b, 115b), thereby adjusting the height of the robot cleaner station (100) or pressurizing and supporting the kitchen cabinet (2).

[0474]

[0475] Alternatively, even when the worker dismantles the robot cleaner station (100), the fixation between the robot cleaner station (100) and the kitchen cabinet (2) can be released through the above process. At this time, the direction in which the worker turns the work tool may be the opposite direction to the direction in which the robot cleaner station (100) was fixed.

[0476]

[0477] Therefore, according to the present invention, when installing or removing a robot cleaner station (100), there is an effect in which the height of a rear supporter that is difficult for a worker to reach can be easily adjusted by simply inserting a work tool from the front and turning it.

[0478]

[0479] Although the present invention has been described in detail through specific examples, this is for the purpose of specifically explaining the present invention, and the present invention is not limited thereto, and it is clear that the present invention can be modified or improved by a person having ordinary knowledge in the relevant field within the technical spirit of the present invention.

[0480] All simple modifications or changes of the present invention fall within the scope of the present invention, and the specific scope of protection of the present invention will be made clear by the appended claims.
