Description

Robot Vacuum Station

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

[0002]

[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 CN219206761U discloses a device for washing a robot cleaner at the bottom of a washing machine.

[0010] The above washing device can wash the robot cleaner using the lower space of the washing machine.

[0011] Additionally, the robot cleaner is cleaned using the water supply and drain connected to the washing machine, so a separate water supply and drain structure is not required.

[0012] However, the above-mentioned cleaning device has a limitation in that it only washes the robot cleaner and does not have a function to dry the robot cleaner.

[0013] Therefore, the above-mentioned cleaning device can only be used when cleaning a robot vacuum cleaner, and has limitations in that it cannot provide basic functions such as drying, and must be equipped with a separate module equipped with a drying function.

[0014] Meanwhile, Chinese utility model registration 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.

[0015] 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.

[0016] 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.

[0017] In addition, since the above-mentioned vacuum cleaner station always has an open space through which the robot vacuum cleaner enters and exits, there is a limitation that the drying efficiency may be reduced if a configuration for drying the mop of the robot vacuum cleaner is provided because the heat is discharged to the outside.

[0018] Meanwhile, Chinese utility model registration CN 218922468 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.

[0019] The above-mentioned cleaning station is configured to supply dry air to a cleaning tank that washes the mop of the robot cleaner and to dry the mop placed on the upper side of the cleaning tank.

[0020] However, when drying mops in an open space indoors, such as the above-mentioned cleaning station, there is a limit to the indoor humidity being increased by the water vapor generated during the drying process, and the foul odor being spread indoors as the sewage generated while washing the mop dries.

[0021] In addition, in the process of drying a mop in an open space, the heated air spreads outward, so there is a limit to the reduction in energy efficiency as the heated air must be continuously supplied for a long time.

[0022]

[0023] 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.

[0024] In addition, the purpose is to provide a robot cleaner station that can accommodate a robot cleaner in the lower space of a kitchen cabinet with a predetermined height restriction.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] In addition, the problem to be solved is to provide a robot cleaner station that can prevent excessive humidity in the space where the robot cleaner is placed due to moisture vapor generated while drying the mop of the robot cleaner, which can cause electronic components to malfunction or dust to rot.

[0029] In addition, the present invention aims to solve the problem of providing a robot vacuum cleaner station capable of increasing drying efficiency during the process of drying a mop.

[0030] In addition, the purpose is to provide a robot cleaner station that can prevent vaporized moisture from leaking into the kitchen during the drying process of the robot cleaner's mop.

[0031] In addition, the purpose is to provide a robot cleaner station that can prevent foul odors that may be generated when the waste water used to wash the mop evaporates during the process of drying the mop of the robot cleaner from entering the kitchen.

[0032]

[0033] In order to solve the above-described problem, a robot cleaner station according to the present invention comprises: a housing; a mounting portion disposed in the housing and forming a receiving space in which at least a part of a robot cleaner is accommodated; and a mop drying portion for drying a mop of the robot cleaner; wherein the mop drying portion comprises an outside air supply module for discharging heated air into the receiving space; and an air intake port disposed inside the housing and for sucking in air inside the housing.

[0034] Through this, the robot cleaner station can supply heated air to the robot cleaner to dry the mop, and absorb moisture that is vaporized during the drying process and spreads inside the housing and discharge it to the outside.

[0035] Meanwhile, a plurality of the air intakes may be arranged at the same distance from the front end of the housing.

[0036] At this time, the mop drying unit further includes an air exhaust duct in which the air intake port is formed and an air exhaust path communicating with the air intake port is formed inside, and the air exhaust duct may be connected to an exhaust fan on one side and branched into multiple parts on the other side.

[0037] In addition, the external air supply module may include an external air inlet for introducing external air of the housing; a heater for heating the air introduced through the external air inlet; and an external air discharge port for discharging the air heated by the heater into the receiving space.

[0038] In addition, on the other hand, the outdoor air supply module may further include a blower fan that provides a flow force to the air introduced through the outdoor air inlet port, thereby discharging heat to the mop to disperse moisture and increase drying efficiency.

[0039] At this time, the temperature of the heat discharged from the external air supply module may be 65 degrees Celsius or higher.

[0040] With this configuration, the outside air can be heated to dry the mop of the robot vacuum cleaner.

[0041] Meanwhile, the robot cleaner station according to the present invention may further include a door disposed in the housing and opening and closing an entrance through which the robot cleaner enters and exits the housing.

[0042] At this time, the external air supply module can discharge heated air while the door is closed. Accordingly, the temperature of the space where the robot cleaner is housed can be increased, thereby drying the mop.

[0043] Meanwhile, if the humidity in the receiving space exceeds a preset standard humidity, the door may be opened. This prevents the humidity in the receiving space from rising excessively.

[0044] Meanwhile, the mop drying unit may further include an exhaust fan that provides fluidity to air flowing in through the air intake port.

[0045] At this time, if the humidity of the above-mentioned receiving space is higher than the preset exhaust humidity, the exhaust fan may be operated.

[0046] Additionally, air drawn into the air intake can be discharged through a drain pipe installed in the kitchen cabinet. This allows air to be discharged through the drain pipe when the humidity in the storage space increases.

[0047] Therefore, the hot and humid air generated during the mop drying process can be discharged into the drain pipe rather than into the indoor space. Furthermore, any foul odors that may be generated during the mop drying process can be discharged into the drain pipe, preventing foul odors from forming in the kitchen.

[0048] Meanwhile, the air intake may be positioned higher than the robot cleaner when the robot cleaner is connected to the mounting device. This can increase the efficiency of inhaling the steam that rises as the mop dries.

[0049] At this time, at least a part of the air intake can be placed vertically above the position where the left-right width of the robot cleaner is the greatest.

[0050] Through this, it is possible to prevent steam generated during the drying process of the mop from flowing forward, and to prevent malfunction of the sensor positioned at the front of the robot cleaner.

[0051] Additionally, the distance from the outside air outlet to the air intake may be greater than the distance from the outside air outlet to the mop.

[0052] Additionally, the air intake may be positioned above the path along which the robot cleaner moves within the housing. This can prevent condensation from forming on the walls within the housing.

[0053] Meanwhile, the robot cleaner station according to the present invention further includes a dust collection unit that collects dust from the dust bin of the robot cleaner through the operation of a dust collection motor; and the exhaust fan may be positioned between the dust collection motor and the external air supply module. This allows components to be placed in a limited space, and secures space for arranging a passage for discharging steam.

[0054] Meanwhile, depending on the embodiment, air drawn into the air intake can be re-supplied to the heat supply module. This has the effect of increasing energy efficiency by re-supplying heated air to the heater.

[0055] Meanwhile, the housing includes an upper cover that covers the upper side of the receiving space and faces the lower side of the kitchen cabinet; and the air intake can be arranged in the upper cover.

[0056] That is, the air exhaust duct in which the air intake is formed can be provided on the upper cover.

[0057]

[0058] As described above, according to the robot cleaner station of 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] Additionally, since detergent can be added as needed, it has the effect of increasing the cleaning effect of the mop.

[0064] 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.

[0065] 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.

[0066] In addition, the problem to be solved is to provide a robot cleaner station that can prevent excessive humidity in the space where the robot cleaner is placed due to moisture vapor generated while drying the mop of the robot cleaner, which can cause electronic components to malfunction or dust to rot.

[0067] In addition, the present invention aims to solve the problem of providing a robot vacuum cleaner station capable of increasing drying efficiency during the process of drying a mop.

[0109] 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.

[0110]

[0111] 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.

[0112] 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.

[0113] Additionally, the kitchen cabinet (2) may be equipped with a worktop that can serve as a sink, cooking surface, or work surface.

[0114] 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.

[0115] In general, a kitchen cabinet (2) with a width of 600 mm in the front-back direction and a width of 600 mm in the left-right direction can be used.

[0116] A cleaning system (1) according to another embodiment of the present invention may be provided on the lower side of a structure including at least one of a water supply pipe and a drain pipe. Specifically, the water supply pipe may refer to a conduit connected to an external water source that supplies fluid to the structure, and the drain pipe may refer to a conduit that discharges fluid discharged from the structure into a sewer.

[0117] 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).

[0118] 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).

[0119] 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).

[0120] 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)).

[0121] For example, the mounting space (24) may have a height of 200 mm or less, and typically a height of 160 mm or less.

[0122] 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.

[0123] 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.

[0124]

[0125] 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.

[0126] 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.

[0127] Additionally, although not shown, the kitchen cabinet (2) may be equipped with a water supply pipe. Through the water supply pipe, tap water (or purified water) may be supplied to the cleaning system (1).

[0128] Below, the specific structure of the vacuum cleaner system (1) will be described.

[0129]

[0130] Meanwhile, FIGS. 3 to 5 illustrate drawings for explaining a cleaning system according to an embodiment of the present invention.

[0131] 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).

[0132] 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).

[0133]

[0134] Meanwhile, FIGS. 6 to 9 disclose drawings for explaining a robot cleaner in a cleaner system according to an embodiment of the present invention.

[0135] The structure of the robot vacuum cleaner (200) is described below with reference to FIGS. 6 to 9.

[0136] 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.

[0137] 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.

[0138] 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.

[0139] 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.

[0140] 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).

[0141] 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).

[0142] 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.

[0143] 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).

[0144] When viewed from above or below, the body (210) can be formed in various shapes, such as circular, oval, or square.

[0145] 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.

[0146] 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.

[0147] The lower body may be formed with an intake (211) for air intake and a hole for accommodating a pair of wheels (260).

[0148] 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).

[0149] 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.

[0150] 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.

[0151] 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.

[0152] 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.

[0153] 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).

[0154] 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).

[0155]

[0156] A dust bin (220) may be provided to suck in external dust and air and store the dust.

[0157] 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.

[0158] The dustbin (220) may be provided inside the body (210). At this time, the dustbin (220) may be fixedly connected to the body (210) or may be provided in a detachable manner according to an embodiment.

[0159] 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.

[0160] 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).

[0161] 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).

[0162] 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).

[0163]

[0164] 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).

[0165] 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.

[0166] 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).

[0167] 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.

[0168] 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), respectively.

[0169] 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.

[0170] 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).

[0171]

[0172] The rotary cleaner (240) includes a rotary plate (241) and a mop (242).

[0173] 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.

[0174] 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.

[0175] 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 floor surface, or may be inclined with the floor surface. 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.

[0176] A pair of rotating plates (241) can be symmetrical to each other.

[0177] The mop (242) can be attached to the lower side of the turntable (241) so as to face the floor surface.

[0178] 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, or may be inclined with the floor surface.

[0179] 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).

[0180] 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.

[0181]

[0182] 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.

[0183] 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).

[0184]

[0185] 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).

[0186] The wheel (260) is provided on the body (210) and can roll on the floor surface.

[0187] 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.

[0188] 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.

[0189] 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.

[0190] 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.

[0191] 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).

[0192] 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).

[0193] 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).

[0194] Additionally, the battery can supply power to the sensor unit (not shown) and the control unit (not shown).

[0195] 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).

[0196]

[0197] 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.

[0198] Referring to FIGS. 10 and 11, the robot cleaner station (100) of the present invention is described as follows.

[0199] A robot cleaner (200) can be accommodated in a robot cleaner station (100). A robot cleaner (200) can be coupled to a mounting portion (120) of the robot cleaner station (100).

[0200] The robot vacuum cleaner station (100) may include a housing (110).

[0201] 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.

[0202] The housing (110) may have a space formed therein that can accommodate a mounting portion (120), a dust collection path (130), a dust collection portion (140), a dust collection motor (152), a mop washing portion (160), a mop drying portion (170), and an exhaust path (125a).

[0203] 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.

[0204] The housing (110) includes an outer wall (111) forming an exterior appearance. The outer wall (111) may refer to a surface formed along the direction of gravity.

[0205] For example, the outer wall (111) may be installed at a predetermined interval on the lower side of the kitchen cabinet (2). As another example, the housing (110) may further include a bottom portion (112) facing the floor of the kitchen, and the outer wall (111) may be connected through the bottom portion (112). As another example, the housing (110) may further include a bottom portion (112) facing the floor of the kitchen and an upper cover (113) facing the lower plate (23) of the kitchen cabinet (2), and the upper and lower ends of the outer wall (111) may be connected to each other through the bottom portion (112) and the upper cover (113). As another example, the housing (110) may further include a third outer wall member (111c) facing the bottom portion (112), the upper cover (113), and the wall of the building.

[0206] 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.

[0207] The outer wall (111) may be composed of a first outer wall member (111a), a second outer wall member (111b), and a third outer wall member (111c).

[0208] The first outer wall member (111a) can cover one of the two sides of the housing (110), and the second outer wall member (111b) can cover the other one of the two sides of the housing (110). For example, the first outer wall member (111a) can be arranged on the left side of the housing (110), and the second outer wall member (111b) can be arranged on the right side of the housing (110).

[0209] The third outer wall member (111c) can connect the first outer wall member (111a) and the second outer wall member (111b). Specifically, the third outer wall member (111c) can connect the first outer wall member (111a) and the second outer wall member (111b) at the rear.

[0210] With this configuration, components of the robot cleaner station (100) can be accommodated inside the housing (110) (between the first outer wall member (111a), the second outer wall member (111b), and the third outer wall member (111c)).

[0211] Additionally, a robot cleaner (200) may be accommodated inside the housing (110). The housing (110) may be arranged so that the outer wall (111) has a gap greater than the maximum horizontal width of the robot cleaner (200). With this configuration, the robot cleaner (200) can enter and exit inside the housing (110).

[0212] 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).

[0213] 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).

[0214] 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.

[0215] That is, the outer wall (111) of the robot cleaner station (100) can be placed on the left and right sides, respectively.

[0216] 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.

[0217] Through this, the exposure of the robot cleaner station (100) and the robot cleaner (200) to the outside can be minimized.

[0218] 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.

[0219] Meanwhile, although not shown, the housing (110) may be provided with a space through which a water supply hose connected to a water supply pipe passes, a space through which a drain hose for discharging wastewater generated after washing a mop (242) passes, and a space through which a hose for discharging moisture generated during the drying process of the mop (242) passes. For example, a space through which the above hoses can pass may be provided in at least one of the outer wall (111), the third outer wall member (111c), and the upper cover (113) of the housing (110).

[0220]

[0221] The robot vacuum cleaner station (100) may include a mounting portion (120).

[0222] The robot cleaner (200) can be docked to the robot cleaner station (100) via the mounting part (120).

[0223] The robot cleaner (200) and the robot cleaner station (100) can be physically, electrically, and / or tangentially connected via the mounting portion (120). When the robot cleaner (200) is physically, electrically, and / or tangentially connected to the robot cleaner station (100) via the mounting portion (120), the robot cleaner (200) can be said to be docked to the robot cleaner station (100).

[0224] The mounting portion (120) may be placed inside the housing (110). In this case, depending on the embodiment, the mounting portion (120) may be provided so as to be withdrawable from the housing (110) through a drawer (190).

[0225] With this configuration, when the mounting part (120) needs to be cleaned or repaired, or when some parts need to be replaced, the user can easily withdraw and manage the mounting part (120).

[0226] An entrance (127) through which a robot cleaner (200) is introduced may be formed in the mounting portion (120). The entrance (127) may refer to a space formed on the front surface of the robot cleaner station (100).

[0227] 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).

[0228] 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 (111) of the housing (110) may also form a boundary.

[0229] 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 mounting 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.

[0230] 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.

[0231] The door (126) can keep the entrance (127) closed when the robot cleaner (200) is accommodated in the mounting portion (120). In addition, when the robot cleaner (200) starts to move from the mounting portion (120), the door (126) can be rotated to open the entrance (127). In addition, the door (126) can be rotated to close the entrance (127) after the robot cleaner (200) passes through the entrance (127). In addition, the door (126) can be rotated to open the entrance (127) when the robot cleaner (200) approaches from outside the cleaner station (100).

[0232]

[0233] The anchoring portion (120) may include a receiving space (S), a floor member (121), a joining wall (123), and a side wall (124).

[0234] A robot cleaner (200) can be accommodated in the accommodation space (S) of the mounting portion (120). For example, the accommodation space (S) may refer to a space surrounded by a floor member (121), a joining 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 washing plate (122), a joining 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 connected to a power supply terminal (123b), or a space where a robot cleaner (200) is located while the dust bin (220) of the robot cleaner (200) is connected to a dust passage hole (123a).

[0235] 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).

[0236] The bottom member (121) may refer to a part of the bottom portion (112) of the housing (110). Alternatively, the bottom member (121) may be a configuration included in the bottom portion (112) of the housing (110). Alternatively, the bottom member (121) may be a configuration formed on the upper surface of the bottom portion (112) of the housing (110).

[0237] The floor member (121) may include a floor member body (121a), an inclined portion (121b), a wheel mounting portion (121c), an agitator receiving portion (121d), and a washing tank (121e).

[0238] The floor member body (121a) can form the overall appearance of the floor member (121). An inclined portion (121b), a wheel mounting portion (121c), an agitator receiving portion (121d), and a washing tank (121e) can be arranged on the floor member body (121a).

[0239] 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.

[0240] An exhaust passage (125a) may be provided inside the floor member body (121a). Accordingly, air discharged from the dust collection motor (152) may flow through the exhaust passage (125a) formed inside the floor member body (121a) and be exhausted to the exhaust port (125b).

[0241] The slope (121b) can be placed at the entrance through which the robot cleaner (200) climbs in the floor member body (121a).

[0242] 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).

[0243] A wheel guide portion (121ba) may be provided on the slope portion (121b).

[0244] 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.

[0245] An auxiliary wheel guide part (121bb) may be provided on the slope part (121b).

[0246] 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).

[0247] The wheel (260) of the robot cleaner (200) that has moved upward along the wheel guide (121ba) can be mounted on the wheel mounting portion (121c). When the wheel (260) of the robot cleaner (200) is mounted on the wheel mounting portion (121c), a physical connection between the robot cleaner (200) and the robot cleaner station (100) can be formed. The surface of the wheel mounting 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 mounting portion (121c) can extend from the upper end of the wheel guide portion (121ba). The wheel mounting portion (121c) can be connected to the wheel guide portion (121ba) without a step. In this way, the robot cleaner (200) can easily move past the inclined portion (121b) to the wheel mounting portion (121c).

[0248] The wheel mounting 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 fixed 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).

[0249] The shape of the wheel mounting 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 mounting portion (121c), and the wheel (260) can be stably mounted on the arch-shaped wheel mounting portion (121c).

[0250] 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 seated on the wheel mounting portion (121c).

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

[0252] The recessed portion (121da) may be formed to be recessed in the 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 mounting portion (121c), at least a portion of the agitator (250) may be received in the receiving space (121dc) of the recessed portion (121da).

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

[0254] An exhaust port (125b) may be formed on one side of the recessed portion (121da). Specifically, the exhaust port (125b) may be formed on a side surface of the recessed portion (121da). Accordingly, air discharged from the dust collecting motor (152) and passing through the exhaust path (125a) may be exhausted into the receiving space (121dc) of the recessed portion (121da) through the exhaust port (125b).

[0255] 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.

[0256] 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).

[0257] The agitator receiving portion (121d) may be formed between the wheel mounting 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 portion (112). Accordingly, the agitator (250) of the robot cleaner (200) that has moved upward along the inclined portion (121b) may be mounted in 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 mounting portion (121c).

[0258] 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 an exhaust path (125a). The recessed portion (121da) of the agitator receiving portion (121d) and the exhaust 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).

[0259] The washing tank (121e) is configured to accommodate the washing plate (122), which will be described later.

[0262] A protrusion (122a) and a drain hole (122b) may be formed on the washing plate (122). When the mop (242) of the robot cleaner (200) is installed on the washing plate (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 washing plate (122), the mop (242) can be washed by rubbing against the protrusion (122a) that is in a stationary state.

[0263] In addition, the washing plate (122) may be formed to slope downward toward the center. Accordingly, the washing water flowing along the inclined washing plate (122) can, after washing the mop (242), drain into the space formed between the washing plate (122) and the washing tank (121e) through the drain hole (122b).

[0264]

[0265] 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 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).

[0266]

[0267] A dust passage hole (123a) may be formed in the mounting portion (120) to allow air from outside the housing (110) to flow into the inside. Specifically, a dust passage hole (123a) may be formed in the joining wall (123) of the mounting portion (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 a robot cleaner (200). The dust passage hole (123a) may be communicated with a dust outlet (221) of the dust bin (220) of the robot cleaner (200). The dust passage hole (123a) may be formed in a hole shape corresponding to the shape of the dust bin (220) 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 (221) of the dust bin (220). The dust passage hole (123a) may be formed to communicate with the dust collection path (130). 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).

[0268]

[0269] The power supply terminal (123b) can supply power to the robot cleaner (200) coupled to the mounting portion (120).

[0270]

[0271] The robot cleaner station (100) may further include a water supply nozzle (123c).

[0272] The water supply nozzle (123c) can be connected to the supply part (231) of the water tank (230) of the robot cleaner (200). Specifically, the water supply nozzle (123c) can be connected to the inlet of the water tank (230). The inlet is configured to be connected to the water tank (230) of the robot cleaner (200). The water supply nozzle (123c) can supply water supplied from the water supply pipe of the kitchen cabinet (2) to the storage space inside the water tank (230) of the robot cleaner (200).

[0273] When the robot cleaner (200) is docked to the robot cleaner station (100), an electrode sensor (not shown) provided in the robot cleaner (200) can recognize the docking. Accordingly, when the electrode sensor recognizes the docking, water supplied from the water supply pipe of the kitchen cabinet (2) can be supplied to the water tank (230) of the robot cleaner (200) through the water supply nozzle (123c). Here, water supplied from the water supply pipe of the kitchen cabinet (2) and passing through the regulator (162) can be supplied to the water supply nozzle (123c) by selectively opening the flow path of the switching valve (166) described later.

[0274]

[0275] The side wall (124) is configured to spatially separate the receiving space (S) of the mounting portion (120) from the parts of the robot cleaner station (100).

[0276] A pair of side walls (124) can be arranged on the left and right sides of the floor member (121). The side walls (124) can be connected to both ends of the joining wall (123).

[0277] Specifically, the side wall (124) may be composed of a first side wall member (124a) and a second side wall member (124b).

[0278] The first side wall member (124a) may be arranged on one of the two sides of the floor member (121), and the second side wall member (124b) may be arranged on the other of the two sides of the floor member (121). For example, the first side wall member (124a) may be arranged on the left side of the floor member (121), and the second side wall member (124b) may be arranged on the right side of the floor member (121).

[0279] The side wall (124) may extend in a direction intersecting the floor member (121) from the left and right sides of the floor member (121).

The height of the side wall (124) may be formed to correspond to the height of the pedestal (21). Specifically, the height of the side wall (124) may be formed to be the same as the height of the pedestal (21).

[0280] 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, a dust collection unit (140), a detergent container (163), and a waste container (164) can be accommodated in the space between the side wall (124) and the outer wall (111) of the housing (110).

[0281] The dust collection unit (140) and the detergent container (163) can be separated in a sliding manner from the space between the side wall (124) and the outer wall (111) of the housing (110). The width in the left and right direction of the dust collection unit (140) and the detergent container (163) can be formed to correspond to the distance between the side wall (124) and the outer wall (111) of the housing (110).

[0282]

[0283] The dust collection unit (140) can collect dust from the dust bin (220) of the robot cleaner (200). The dust collection unit (140) can be placed inside the housing (110). The dust collection unit (140) can be placed outside the mounting unit (120). At this time, the receiving space (S) can be placed inside the mounting unit (120).

[0284] The dust collection unit (140) may include a dust collection unit housing (141), a dust bag (not shown) and a filter (142), and a dust bag drawer (144).

[0285] The dust collection unit housing (141) can form a space inside which a dust bag (not shown), a filter (142), and a dust bag drawer (144) can be accommodated.

[0286] The dust collection unit housing (141) is connected to a dust bag drawer (144) so ​​that a dust bag can be withdrawn therein, and a dust bag (not shown) can be stored inside the dust bag drawer (144). For example, the dust collection unit housing (141) is formed in a rectangular tube shape with an open front, and the rear internal space can be connected to the first dust collection path (131) and the second dust collection path (132).

[0287] The dust collection unit housing (141) is connected to a dust bag drawer (144) so ​​that a dust bag can be withdrawn therein, and a dust bag (not shown) can be stored inside the dust bag drawer (144). For example, the dust collection unit housing (141) is formed in a rectangular tube shape with an open front, and the rear internal space can be connected to the first dust collection path (131) and the second dust collection path (132).

[0288] One side of the inside of the dust collection unit housing (141) can be communicated with the first dust collection path (131), and the other side can be communicated with the second dust collection path (132). In addition, when a dust bag (not shown) is combined with the dust collection unit housing (141), the dust bag (not shown) can be communicated with the first dust collection path (131) inside the dust collection unit housing (141).

[0289] The dust collection unit housing (141) can be connected to the first dust collection path (131) through an inlet (141a) formed on the upper side. The inlet (141a) may be configured to guide air flowing through the first dust collection path (131) into the interior of a dust bag (not shown). The inlet (141a) can connect the first dust collection 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 dust collection path (131) and the inlet (141a).

[0290] The dust collector housing (141) can be connected to the second dust collection path (132) through an outlet (141b) formed on the lower side. The outlet (141b) may be configured to guide air passing through the dust collector housing (141) to the second dust collection path (132). The outlet (141b) may be arranged at a different height from the inlet (141a). The outlet (141b) may be arranged lower than the inlet (141a). The outlet (141b) may connect the internal space of the dust collector housing (141) and the second dust collection path (132). Therefore, air filtered of dust while passing through the dust bag (not shown) can move to the second dust collection path (132) through the outlet (141b).

[0291] 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.

[0292] 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.

[0293] 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.

[0294] 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.

[0295] A filter (142) may be placed between the dust collection unit housing (141) and the second dust collection path (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 dust collection path (132) via the filter (142).

[0296] The dust bag drawer (144) is connected to the dust collection unit housing (141) so that a dust bag (not shown) can be accommodated inside.

[0297] At this time, the dust bag drawer (144) includes a dust bag drawer body (144a), a handle (144d), and a drawer rail (144e).

[0298] The dust bag drawer body (144a) may provide a space where a dust bag (not shown) can be combined inside. For example, the dust bag drawer body (144a) may be formed in a box shape with an open top, and an inlet (144b) and an outlet (144c) may be formed at the rear so as to be able to communicate with the first dust collection path (131) and the second dust collection path (132).

[0299] For example, the dust bag drawer body (144a) may be formed so that the upper left-right width and the lower left-right width are different. For example, the upper left-right width of the dust bag drawer body (144a) may be formed so that it is larger than the lower left-right width. That is, the interior of the dust bag drawer body (144a) may be formed in a step. Through this, the upper space where the dust bag (not shown) is provided can be maximized, and a path can be formed so that the air passing through the dust bag (not shown) can easily escape to the lower side.

[0300] The upper side of the dust bag drawer body (144a) can be connected to the first dust collection path (131) through the inlet (144b). The inlet (144b) may be configured to guide air flowing through the first dust collection path (131) into the interior of the dust bag (not shown). The inlet (144b) can connect the first dust collection 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 dust collection path (131) and the inlet (144b).

[0301] The dust bag drawer (144) can be connected to the second dust collection path (132) through an outlet (144c) formed on the lower side. The outlet (144c) may be configured to guide air passing through the dust bag drawer (144) to the second dust collection path (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 bag drawer (144) and the second dust collection path (132). Therefore, air from which dust is filtered while passing through the dust bag (not shown) can move to the second dust collection path (132) through the outlet (144c).

[0302] A handle (144d) may be provided at the front of the dust bag drawer body (144a). The handle (144d) may be provided so that a user can grip it. For example, the handle (144d) may include a pair of connecting portions hingedly connected to the front surface of the dust bag drawer body (144a), and a grip portion formed by connecting the pair of connecting portions so that a user can grip it.

[0303] With this configuration, when a user holds the grip portion and pulls it forward, the dust bag drawer body (144a) can be pulled forward and withdrawn together. Therefore, according to the present invention, a user can easily pull the dust bag drawer (144) forward, and then lift the dust bag (not shown) upward to remove and replace it.

[0304] A drawer rail (144e) may be formed on the left and right sides of the dust bag drawer body (144a). The drawer rail (144e) may guide the movement of the dust bag drawer body (144a).

[0305] For example, the drawer rail (144e) may be formed in the form of a groove or rib along the front-back direction on the left and right sides of the dust bag drawer body (144a).

[0306] With this configuration, when the user attaches the dust bag drawer (144) to the dust collection unit housing (141), it can be attached in the correct position, and the dust collection unit (140) and the first dust collection path (131) and the second dust collection path (132) can be connected in the correct position to reduce flow loss.

[0307] Meanwhile, a rail (141c) may also be formed on the inner surface of the dust collector housing (141) corresponding to the drawer rail (144e). The rail (141c) 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 (141c) of the dust collector housing (141) may be formed in a rib or protruding ledge shape.

[0308]

[0309] 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.

[0310] Referring to FIGS. 12 to 17, the dust collection path (130) is described as follows.

[0311] 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).

[0312] Specifically, the dust collection path (130) may include a first dust collection 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 dust collection path (132) that connects the dust collection unit (140) and the dust collection motor (152).

[0313] Meanwhile, in this specification, the first dust collection path (131) may also be referred to as a suction path (131). Hereinafter, for convenience of explanation, both the first dust collection path (131) and the suction path (131) will be referred to as the first dust collection path (131).

[0314] The first dust collection path (131) can connect the dust bin (220) and the dust collection unit (140) of the robot cleaner (200). The first dust collection path (131) can connect the dust bin (220) and the dust collection unit (140) of the robot cleaner (200). The first dust collection path (131) can connect the dust passage hole (123a) of the mounting part (120) and the dust collection unit (140). The first dust collection path (131) can mean a space between the dust bin (220) and the dust collection unit (140) of the robot cleaner (200). The first dust collection path (131) can be formed in a direction close to the horizontal direction. The first dust collection path (131) may be a space formed toward the rear of the dust passage hole (123a), or may be a path formed by bending toward the side of the dust passage hole (123a) so that dust and air can flow. Through the first dust collection path (131), dust in the dust bin (220) of the robot cleaner (200) can move to the dust collection unit (140).

[0315] The second dust collection path (132) can connect the dust collection unit (140) and the dust collection motor (152). The second dust collection path (132) can be formed in a nearly horizontal direction. At this time, the first path (132) and the second path (131) can be formed at different heights. The first dust collection path (131) and the second dust collection path (132) can be formed in a layered structure. The second dust collection path (132) can be arranged lower than the first dust collection path (131). With this configuration, the left-right width and the overall volume of the robot cleaner station (100) can be minimized.

[0316] The dust collection module (150) can provide suction airflow to the dust collection path (130).

[0317] Specifically, the dust collection module (150) may include a dust collection motor housing (151) and a dust collection motor (152).

[0318] 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.

[0319] An inlet hole (151a) and an outlet hole (151b) may be formed in the dust collecting motor housing (151).

[0320] The internal space of the dust collecting motor housing (151) can be communicated with the second dust collecting passage (132) through the inlet hole (151a). Therefore, the inlet hole (151a) can guide the air flowing through the second dust collecting passage (132) to the dust collecting motor (152).

[0321] The internal space of the dust collecting motor housing (151) can be communicated with the exhaust path (125a) through the exhaust hole (151b). Therefore, the exhaust hole (151b) can guide air passing through the dust collecting motor (152) to the exhaust path (125a).

[0322] 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).

[0323] 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).

[0324] 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.

[0325] The dust collecting motor (152) may have one side connected to the second dust collecting passage (132) and the other side connected to the exhaust passage (125a). When the dust collecting motor (152) is driven, air flowing through the second dust collecting passage (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 exhaust passage (125a) and be exhausted to the exhaust port (125b).

[0326] Meanwhile, a virtual dust collecting motor axis (AC) extending from 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.

[0327] 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).

[0328] The exhaust section (125) may be composed of an exhaust path (125a) and an exhaust port (125b).

[0329] The exhaust path (125a) can provide a path through which air discharged from the dust collecting motor (152) flows. The exhaust path (125a) can be arranged inside the bottom member body (121a).

[0330] The exhaust path (125a) may be connected to the dust collecting motor (152) in a flow path manner. The exhaust path (125a) may refer to a flow path connecting the discharge hole (151b) and the exhaust port (125b). One end of the exhaust path (125a) may be connected to the internal space of the dust collecting motor housing (151), and the other end of the exhaust path (125a) may be connected to the receiving space (121dc) of the recessed portion (121da). Specifically, one end of the exhaust path (125a) may be connected to the discharge hole (151b), and the other end of the exhaust path (125a) may be connected to the exhaust port (125b).

[0331] The exhaust path (125a) may be a path formed horizontally within the housing (110). The exhaust path (125a) may be connected to the dust collecting motor (152) in a flow direction. Specifically, one end of the exhaust path (125a) may be connected to the dust collecting unit (140), and the other end of the exhaust path (125a) may be connected to the exhaust port (125b).

[0332] 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 exhaust path (125a) can be discharged to the outside of the housing (110) through the exhaust port (125b).

[0333] 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).

[0334]

[0335] FIGS. 18 to 20 are drawings illustrating an exhaust 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 an exhaust 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.

[0336] Referring to FIGS. 18 to 23, the exhaust path of the robot cleaner station according to the embodiment of the present invention is described as follows.

[0337] The exhaust path (125a) according to an embodiment of the present invention can guide air discharged from the dust collecting motor (152) to the suction part (211) of the robot cleaner (200).

[0338] The exhaust path (125a) can create a structure in which the air discharged from the dust collecting motor (152) is not discharged to the outside, but is guided to the suction part (211) of the robot cleaner (200), 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 re-introduced into the interior of the robot cleaner (200) to form an exhaust path, thereby having the effect of preventing the interior of the kitchen cabinet (2) from being damaged.

[0339] The exhaust 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 exhaust path (125a) may refer to a recessed portion (121da) of the agitator receiving portion (121d). The exhaust 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).

[0340] 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 dust collecting passage (131), the dust collecting section (140), the second dust collecting passage (132), the dust collecting motor (152), the exhaust passage (125a), and the exhaust port (125b), and then be discharged to the receiving space (S).

[0341] 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).

[0342] 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.

[0343]

[0344] Meanwhile, referring again to FIGS. 12 to 23 and FIG. 31, the flow path structure of the robot cleaner station (100) according to the embodiment of the present invention will be described as follows.

[0345] According to an embodiment of the present invention, the inlet (141a) and the outlet (141b) may be formed at different heights on the side surface of the dust collection unit (140). In other words, the inlet (141a) and the outlet (141b) may be formed in an up-down direction on the side surface of the dust collection unit (140).

[0346] Specifically, the inlet (141a) and the outlet (141b) can be formed at different heights on the side of the dust collector housing (141).

[0347] As shown in Fig. 15, the side of the dust collector housing (141) may be formed in a step shape.

[0348] Specifically, the dust collector housing (141) may include an upper surface (1411), a first side surface (1412), a second side surface (1413), and a lower surface (1414).

[0349] The upper surface (1411) can cover the upper side of the dust collector housing (141). The first side surface (1412) and the second side surface (1413) can cover the rear side of the dust collector housing (141). The lower surface (1414) can cover the lower side of the dust collector housing (141).

[0350] The inlet (141a) may be formed in the first side portion (1412), and the outlet (141b) may be formed in the second side portion (1413). The first side portion (1412) may extend downward from the upper surface portion (1411), and the second side portion (1413) may extend upward from the lower surface portion (1414).

[0351] The first side portion (1412) and the second side portion (1413) may be formed to be stepped from each other. That is, the outlet (141b) formed in the second side portion (1413) may be positioned further back than the inlet (141a) formed in the first side portion (1412).

[0352] In contrast, the side surface of the dust collector housing (141) may be formed flat. When the side surface of the dust collector housing (141) is formed flat, the first side surface (1412) and the second side surface (1413) may be arranged to overlap vertically. Accordingly, when the side surface of the dust collector housing (141) is formed flat, the inlet (141a) and the outlet (141b) may be arranged to overlap vertically.

[0353] The inlet (141a) and the outlet (141b) can be opened in the same direction with respect to the dust collection unit (140).

[0354] Specifically, in this specification, when the direction in which the dust bag drawer (144) is taken out is referred to as the front and the direction in which the dust bag drawer (144) is introduced is referred to as the rear, the inlet (141a) and the outlet (141b) can be opened toward the rear.

[0355] The direction in which the inlet (141a) is opened and the direction in which the outlet (141b) is opened can be parallel to each other in the vertical direction.

[0356] The inlet (141a) and the outlet (141b) may be formed on the same side of the dust collection unit (140). Specifically, the inlet (141a) and the outlet (141b) may be formed on the rear side of the dust collection unit housing (141).

[0357] Referring to FIG. 31, the robot cleaner station (100) according to an embodiment of the present invention may further include a dust collecting motor axis (AC) extending the rotation axis of the dust collecting motor (152).

[0358] The dust collecting motor axis (AC) can be arranged parallel to the bottom (112). In other words, the dust collecting motor axis (AC) can be arranged in a horizontal direction.

[0359] Additionally, the dust collecting motor (152) and the dust collecting unit (140) can be arranged in a horizontal direction.

[0360] Through this, the vertical height of the robot cleaner station (100) is minimized, enabling a compact configuration of the robot cleaner station (100).

[0361] Therefore, the robot cleaner station (100) according to the embodiment of the present invention can be installed in a narrow space, such as the lower space of a kitchen cabinet including a sink, by minimizing the space it occupies in the horizontal direction and at the same time minimizing the space it occupies in the vertical direction.

[0362] At least a portion of the first dust collection path (131) and at least a portion of the second dust collection path (132) may be arranged to overlap each other in the vertical direction. This minimizes the length of the dust collection path (130), thereby reducing path resistance. Furthermore, the space required for installing the robot cleaner station (100) is minimized, thereby maximizing space efficiency.

[0363] At least a portion of the first dust collection path (131) and at least a portion of the second dust collection path (132) can be arranged in the same direction with respect to the dust collection unit (140).

[0364] Specifically, when the direction in which the dust bag drawer (144) is taken out is referred to as the front and the direction in which the dust bag drawer (144) is taken in is referred to as the rear, at least a portion of the first dust collection path (131) and at least a portion of the second dust collection path (132) can be placed at the rear of the dust collection unit (140).

[0365] The inlet (141a) and the dust collecting motor (152) can be arranged in the same direction with respect to the internal space of the dust collecting unit (140). Therefore, the inlet (141a) and the dust collecting motor (152) can be arranged at the rear with respect to the internal space of the dust collecting unit (140).

[0366] At least a portion of the first dust collection path (131) and at least a portion of the exhaust path (125a) may overlap in the vertical direction. Through this, the overall path length of the robot cleaner station (100), including the dust collection path (130) and the exhaust path (125a), is minimized, so that the path resistance is reduced as described above, and the space required for installing the robot cleaner station (100) is minimized, so that space efficiency can be maximized.

[0367] At least a portion of the first dust collection path (131) and at least a portion of the exhaust path (125a) may be arranged in the same direction with respect to the dust collection unit (140). At least a portion of the second dust collection path (132) and at least a portion of the exhaust path (125a) may be arranged in the same direction with respect to the dust collection unit (140). Accordingly, at least a portion of the first dust collection path (131) and at least a portion of the second dust collection path (132) may be arranged at the rear of the dust collection unit (140).

[0368]

[0369] 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, and FIG. 26 is a cross-sectional perspective view illustrating a space formed between a washing plate and a washing tank of a robot cleaner station according to an embodiment of the present invention.

[0370] 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.

[0371] A robot cleaner station (100) according to an embodiment of the present invention may include a mop washing unit (160). The mop washing unit (160) may wash a mop (242) of a robot cleaner (200) coupled to a mounting unit (120).

[0372] The mop washing unit (160) may include a washing water supply unit (161) that discharges washing water to the washing plate (122), a detergent container (163) that stores liquid including detergent, and a waste water container (164) that stores washing water after washing the mop (242).

[0373] In the washing water supply unit (161), purified water and detergent can be mixed to produce washing water for washing the mop (242).

[0374] A pair of washing water supply units (161) may be spaced apart from each other on the rear side of the joining wall (123). The washing water supply units (161) may discharge washing water toward the washing plate (122) from the upper sides of both ends of the washing plate (122). At this time, purified water supplied from the water supply pipe of the kitchen cabinet (2) and passing through the regulator (162) may be branched to both sides through a branch path (161a) and connected to each of the washing water supply units (161) spaced apart from each other. That is, the branch 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 supply units (161), and the other of the branched ends may be connected to the other of the pair of washing water supply units (161).

[0375] The washing water supply 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).

[0376] A water purification inlet (161b), a detergent inlet (161c), and a water discharge outlet (not shown) may be formed in the washing water supply unit (161).

[0377] The purified water inlet (161b) is configured to guide purified water supplied from the water supply pipe of the kitchen cabinet (2) to the washing water supply unit (161). Specifically, the water supply pipe of the kitchen cabinet (2) is connected to a regulator (162), so that the flow rate supplied from the water supply pipe can be adjusted. In addition, a portion of the purified water that has passed through the regulator (162) can be supplied to the water tank (230) of the robot cleaner (200) through the water supply nozzle (123c), and the remainder can be introduced into a pair of washing water supply units (161) that are spaced apart from each other through the purified water inlet (161b).

[0378] The detergent inlet (161c) is configured to guide the liquid containing detergent supplied from the detergent container (163) to the washing water supply unit (161). Specifically, the liquid containing detergent stored in the detergent container (163) can be supplied to the washing water supply unit (161) via a pump (not shown).

[0379] In addition, the detergent and purified water introduced into the washing water supply unit (161) can be mixed and used as washing water. The washing water supply unit (161) can discharge the washing water to the upper surface of the washing plate (122) through the washing water discharge port. The washing water discharge port can be formed on the lower surface of the washing water supply 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 plate (122).

[0380] The detergent container (163) can store liquids including detergent.

[0381] The detergent container (163) includes a detergent container body (163a), a handle (163b), and a detergent container rail (163c).

[0382] The detergent container body (163a) may provide a space for storing liquid, including detergent. For example, the detergent container body (163a) may be formed in a box shape with an open top, and the rear may be connected to a washing water supply unit (161).

[0383] 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.

[0384] 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.

[0385] 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).

[0386] 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).

[0387] 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.

[0388] 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).

[0389] 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 plate (122) can be drained into the drain hole (122b) while descending along the slope of the washing plate (122) after washing the mop (242). The washing water passing through the drain hole (122b) accumulates between the washing tank (121e) and the washing plate (122). In addition, the washing water accumulated between the washing tank (121e) and the washing plate (122) can be introduced into the wastewater tank (164) through the wastewater suction path (164b).

[0390] Washing water stored in the wastewater tank (164) can be drained to the drain pipe (25) of the kitchen cabinet (2) through the wastewater discharge path (164a). One end of the wastewater discharge path (164a) can be connected to the wastewater tank (164), and the other end can be connected to the drain pipe (25). At this time, the washing water stored in the wastewater tank (164) can be drained to the drain pipe (25) by flowing through the wastewater discharge path (164a) by the centrifugal pump (168).

[0391] The sewage discharge path (164a) connected to the sewage tank (164) can be connected upstream (25b) based on the drain trap (25a) of the drain pipe (25) of the kitchen cabinet (2). This is because, if the sewage discharge path (164a) is connected downstream (25c) based on the drain trap (25a) of the drain pipe (25), foul odors or fluids inside the drain pipe (25) may flow back into the sewage discharge path (164a).

[0392] Additionally, the mop washing unit (160) may include a check valve (165). The check valve (165) may prevent the fluid inside the drain pipe (25) from flowing back into the sewage discharge passage (164a). The check valve (165) may be provided at the other end of the sewage discharge passage (164a) connected to the drain pipe (25).

[0393] 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.

[0394]

[0395] Meanwhile, referring again to FIGS. 24 to 26, the horizontal arrangement of the mop washing unit of the robot cleaner station according to the embodiment of the present invention will be described as follows.

[0396] The mop washing unit (160) may be placed between the outer wall (111) and the mounting unit (120). At this time, the outer wall (111) may be placed between the robot cleaner (200) mounted on the floor unit (112) and the outer wall (111).

[0397] In other words, the mop washing unit (160) can be placed on the side of the mounting unit (120).

[0398] Specifically, the sewage tank (164) and detergent tank (163) can be placed between the first outer wall member (111a) and the first side wall member (124a).

[0399] The washing water supply unit (161) may be placed on the rear side of the mounting unit (120). Specifically, the washing water supply unit (161) may be placed on the rear side of the joining wall (123).

[0400] The sewage tank (164) may be placed on the side of the mounting portion (120). Specifically, the sewage tank (164) may be placed on the side of the first side wall member (124a).

[0401] The detergent container (163) arranged vertically with the waste water tank (164) can be arranged on the side of the mounting portion (120). Specifically, the detergent container (163) can be arranged on the side of the first side wall member (124a).

[0402] According to an embodiment of the present invention, the robot cleaner station (100) may be arranged such that the components forming the mop washing unit (160) are arranged in a horizontal direction relative to the receiving space (S) in which the robot cleaner (200) is received. Accordingly, the space required for installing the robot cleaner station (100) is minimized, and thus it may be installed in the lower space of a low kitchen cabinet, for example.

[0403] Meanwhile, the mop washing unit (160) may further include a heater (not shown). The heater may heat water supplied to the mop (242) through the washing water supply unit (161). Accordingly, hot water may be supplied to the mop (242) through the heater, thereby increasing the cleaning power of the mop (242).

[0404] A switching valve (166) may be provided on the outlet side of the regulator (162). The switching valve (166) may be configured to selectively supply purified water that has passed through the regulator (162) to the water supply nozzle (123c) or the heater. The switching valve (166) may be referred to as a two-way valve, a two-way valve, or a two-way valve.

[0405] The mop washing unit (160) may include a diaphragm pump (167). The diaphragm pump (167) may suck up the washing water accumulated between the washing tank (121e) and the washing plate (122) and discharge it into the sewage tank (164). At this time, the diaphragm pump (167) may introduce the washing water accumulated between the washing tank (121e) and the washing plate (122) into the sewage tank (164) through the sewage suction path (164b).

[0406]

[0407] FIGS. 32A and 32B are front views 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 drawing illustrating a state in which a dust collection unit and a detergent container are pulled out from a robot cleaner station according to an embodiment of the present invention.

[0408] The arrangement of the robot cleaner station (100) according to an embodiment of the present invention will be described with reference to FIG. 4, FIG. 32a, FIG. 32b, and FIG. 33 as follows.

[0409] 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).

[0410] 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.

[0411] 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).

[0412] At this time, if both a dust collection unit (140) and a mop washing unit (160) are provided, the mounting unit (120) can be placed between the dust collection unit (140) and the mop washing unit (160).

[0413] For example, an entrance (127) and a door (126) may be arranged at the front of the robot cleaner station (100). In addition, a mounting part (120) to which a robot cleaner (200) is coupled may be arranged at the rear from the entrance (127). At this time, a dust collection part (140) may be arranged at a predetermined distance from the front end of the robot cleaner station (100). In addition, a mop washing part (160) may also be arranged at a predetermined distance from the front end of the robot cleaner station (100) at the rear.

[0414] 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).

[0415] 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 (110).

[0416] 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.

[0417] 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.

[0418] Meanwhile, the rear end 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 mounting unit (120), the dust collection unit (140), and the dust collection motor (152) within a limited space.

[0419] In addition, a path through which washing water for washing the mop (242) can flow and a pump providing the flow force of the washing water can be at least partially arranged between the rear end of the housing (110) and the rear end of the mop washing unit (160). With this configuration, the path through which washing water flows from the water supply pipe can be minimized. In addition, there is an effect of minimizing the total space occupied by the mounting unit (120), the mop washing unit (160), and the path through which the washing water flows within a limited space.

[0420] Meanwhile, the robot cleaner station (100) may have a mop drying unit (170) positioned rearward of the mounting unit (120). At this time, the mop drying unit (170) may be positioned between the rear end of the mounting unit (120) and the rear end of the housing (110).

[0421] Accordingly, the robot cleaner station (100) according to the embodiment of the present invention may have a dust collection unit (140) and a mop washing unit (160) arranged on the left and right sides of the mounting unit (120), and a mop drying unit (170) arranged on the rear side.

[0422] That is, in the robot cleaner station (100) according to the embodiment of the present invention, the dust collection unit (140), the mop washing unit (160), and the mop drying unit (170) can all be placed within a predetermined distance range from the outer edge of the mounting unit (120).

[0423] Through this arrangement, there is an effect in which the mounting unit (120), dust collection unit (140), mop washing unit (160), and mop drying unit (170) can all be placed in the narrowest space on the horizontal plane.

[0424] 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).

[0425] In addition, by this arrangement, the robot cleaner station (100) of the present invention can place all components within a limited height.

[0426] Specifically, based on the state in which the robot cleaner (200) is coupled to the mounting portion (120), at least a portion of the dust collection portion (140) may be positioned lower than the uppermost portion of the robot cleaner (200). In addition, at least a portion of the mop washing portion (160) may be positioned lower than the uppermost portion of the robot cleaner (200). In addition, at least a portion of the mop drying portion (170) may be positioned lower than the uppermost portion of the robot cleaner (200). In addition, at least a portion of the mop washing portion (160) may be positioned lower than the uppermost portion of the dust collection portion (140).

[0427] In addition, based on the state in which the robot cleaner (200) is coupled to the mounting portion (120), the top of the robot cleaner (200) may be positioned higher than the dust bag (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).

[0428] From another perspective, when a virtual plane (H) parallel to the kitchen floor is drawn with the robot cleaner (200) attached to the mounting portion (120), the plane (H) can pass through the robot cleaner (200), the dust collection portion (140), the mop washing portion (160), and the mop drying portion (170). This means that all components can be placed within a certain height range.

[0429] From another perspective, when the robot cleaner (200) is coupled to the mounting portion (120), the mounting portion (120) may be divided into three regions in the vertical direction. At this time, the mounting portion (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 located on both left and right sides of the first region, a dust bag (not shown) and a waste container (164) may be located on both left and right sides of the second region, and only the upper part of the robot cleaner (200) may be located in the third region.

[0430] As a result, the robot cleaner station (100) according to the embodiment of the present invention can have a dust collection unit (140), a mop washing unit (160), and a mop drying unit (170) arranged on three sides surrounding the mounting portion (120) except for the front side where the robot cleaner (200) enters. By this arrangement, even in a situation where the vertical height is limited, it is possible to charge the robot cleaner (200) using a minimum of horizontal space, as well as collect dust from the robot cleaner (200), wash the mop (242), and dry the mop (242).

[0431]

[0432] FIG. 27 is a perspective view illustrating a mop drying unit of a robot cleaner station according to a first embodiment of the present invention, FIGS. 28 and 29 are enlarged views of a mop drying unit of a robot cleaner station according to a first embodiment of the present invention, and FIG. 30 is a cross-sectional view illustrating how air flows into a heat supply module according to a first embodiment of the present invention.

[0433] Referring to FIGS. 27 to 30, the robot cleaner station (100) according to the first embodiment of the present invention may include a mop drying unit (170). At this time, the mop drying unit (170) may dry the mop (242) of the robot cleaner (200) that has been washed by the mop washing unit (160) or the mop (242) that is wet after the water cleaning task is completed.

[0434] The mop drying unit (170) according to the first embodiment of the present invention may include an external air supply module (171), a steam discharge unit (172), an exhaust fan (173), and a check valve (not shown).

[0435] The outside air supply module (171) can supply heated air to the receiving space (S) and can include an outside air supply path (171a), an outside air inlet (171b), an outside air discharge portion (171c), a heater (171d), and a blower fan (not shown).

[0436] The external air supply path (171a) has a heat supply path formed therein and can connect the external space of the housing (110) and the receiving space (S). An external air inlet (171b) can be arranged on one side of the external air supply path (171a), and an external air discharge portion (171c) can be arranged on the other side. The external air inlet (171b) can be connected to the external space, and the external air discharge portion (171c) can be connected to the receiving space (S).

[0437] An external air inlet (171b) may be formed in the third outer wall member (111c) of the housing (110). Air from outside the housing (110) may be introduced into the external air inlet (171b).

[0438] The outside air discharge portion (171c) may be positioned on the upper side of the washing plate (122). The outside air discharge portion (171c) may be formed to be inclined downward toward the front. That is, the outside air discharge portion (171c) may be formed to discharge air toward the washing plate (122), but may be formed along a direction that crosses the direction in which the washing plate (122) is formed. The outside air discharge portion (171c) may be provided in pairs in a state in which they are open toward the lower side.

[0439] The outside air discharge portion (171c) can be opened toward the cleaning plate (122) when the mop (242) is seated on the cleaning plate (122). The outside air discharge portion (171c) can be positioned adjacent to the mop (242) when the mop (242) is seated on the cleaning plate (122), and can be opened downward so that the discharged air can flow toward the mop (242). The outside air discharge portion (171c) can be opened in a direction facing the mop (242) when the robot cleaner (200) is connected to the seat (120).

[0440] With this configuration, the outside air discharge unit (171c) can discharge air heated by the heater (171d) into the receiving space (S).

[0441] A blower fan (not shown) is placed on an outside air supply path (171a) and can provide a fluid force to blow air toward a receiving space (S). When the blower fan (not shown) is driven, air drawn in through an outside air inlet (171b) can be heated by a heater (171d) and discharged to the receiving space (S) through an outside air discharge portion (171c).

[0442] Therefore, by blowing air through the mop (242) using a blower fan (not shown), moisture can be dispersed, and drying efficiency can be increased.

[0443] The heater (171d) is arranged on the outside air supply path (171a) and can heat the air flowing through the outside air supply path (171a). The heater (171d) can heat the air that is introduced through the outside air inlet (171b) and discharged through the outside air discharge port (171c). The heater (171d) can be arranged on the outside air supply path (171a), but may alternatively be arranged on the outside air discharge port (171c). That is, as long as it can heat the air discharged to the receiving space (S), there are no restrictions on the specific shape or arrangement.

[0444] The heater (171d) may include a heater housing (171da) and a heating element (not shown). The heater housing (110) may be placed on an external air supply path (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 to the accommodation space (S) through the external air discharge portion (171c) to dry the wet mop (242).

[0445]

[0446] The steam exhaust unit (172) can exhaust the hot and humid air in the receiving space (S) generated while drying the mop (242) to the drain pipe (25). The steam exhaust unit (172) can connect the receiving space (S) and the drain pipe (25) of the kitchen cabinet (2).

[0447] One end of the steam discharge unit (172) can be connected to the receiving space (S), and the other end can be connected to the drain pipe (25). Specifically, the air intake port (172a), which is one end of the steam discharge unit (172), can be connected to the receiving space (S), and the air discharge port, which is the other end, can be connected to the drain pipe (25).

[0448] The steam exhaust unit (172) is placed inside the housing (110) and includes an air intake port (172a) that sucks in air inside the housing (110).

[0449] The air intake (172a) can be positioned higher from the ground than the mop (242) when the robot cleaner (200) is mounted on the mounting portion (120). This can increase the efficiency of the mop (242) inhaling the steam that rises as it dries.

[0450] The steam discharge unit (172) may be connected downstream (25c) with respect to the oil trap (25a) of the drain pipe (25) of the kitchen cabinet (2). This is because, when the steam discharge unit (172) is connected upstream (25b) with respect to the oil trap (25a) of the drain pipe (25), the heat exhausted through the steam discharge unit (172) may not pass through the drain pipe (25) due to water accumulated in the oil trap (25a).

[0451] Meanwhile, the steam discharge unit (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 first outer wall member (111a) of the housing (110), and the other branch may penetrate the second outer wall member (111b) of the housing (110). The steam discharge unit (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 by the steam discharge unit (172) may flow through the steam discharge unit (172) branched to both sides and be exhausted downstream (25c) based on the oil trap (25a) of the drain pipe (25).

[0452] The exhaust fan (173) can exhaust air from the receiving space (S) through the steam discharge unit (172) to the drain pipe (25). The exhaust fan (173) can cause air to flow along the steam discharge unit (172). The exhaust fan (173) can be placed on the steam discharge unit (172).

[0453] When the exhaust fan (173) is driven, air in the receiving space (S) can be drawn into the air intake port (172a). The air drawn into the air intake port (172a) can flow through the steam discharge unit (172) and be exhausted to the drain pipe (25). Specifically, when the exhaust fan (173) is driven and the air flowing through the steam discharge unit (172) can be exhausted downstream (25c) based on the oil trap (25a) of the drain pipe (25). Through this, when the humidity of the receiving space (S) increases, the air can be exhausted to the drain pipe (25).

[0454] Accordingly, the hot and humid air generated during the drying process of the mop (242) can be discharged to the drain pipe (25) rather than to the indoor space. In addition, the foul odor that may be generated during the drying process of the mop (242) can be discharged to the drain pipe (25), thereby preventing foul odor from being generated in the kitchen.

[0455] 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 unit (172). The check valve may be provided at the other end of the steam discharge unit (172) connected to the drain pipe (25).

[0456] Therefore, according to the present invention, heated air is supplied to the robot cleaner (200) to dry the mop (242), and moisture that is vaporized during the drying process and spreads inside the housing (110) can be sucked in and discharged to the outside.

[0457]

[0458] FIG. 31 is a drawing illustrating a mop drying unit of a robot cleaner station according to a second embodiment of the present invention.

[0459] The mop drying unit (170) according to the second embodiment of the present invention may include an external air supply module, an air exhaust path, an exhaust fan, and a check valve.

[0460] To avoid redundant description, except for what is specifically mentioned in the second embodiment of the present invention, other configurations may be based on the contents of the mop drying unit (170) according to the first embodiment of the present invention.

[0461] In the second embodiment of the present invention, the steam discharge path of the mop drying unit can discharge the high temperature and humidity air of the receiving space (S) generated while drying the mop (242) to the outside of the housing (110).

[0462] According to the second embodiment of the present invention, the steam discharge passage of the mop drying unit may be arranged in a space formed between the side wall (124) and the outer wall (111) of the housing (110). Specifically, in the second embodiment of the present invention, the steam discharge passage may be arranged on the upper side of the waste tank (164), between the waste tank (164) and the detergent tank (163), or on the lower side of the detergent tank (163). In the second embodiment of the present invention, the air inlet of the air discharge passage may be formed on the side wall (124), and the air outlet of the air discharge passage may be formed on the front side of the housing (110). In the second embodiment of the present invention, the air outlet may be arranged on the upper side of the waste tank (164), between the waste tank (164) and the detergent tank (163), or on the lower side of the detergent tank (163). Therefore, in the second embodiment of the present invention, one end of the air exhaust path may be connected to the receiving space (S), and the other end may be connected to the external space of the housing (110).

[0463] The exhaust fan of the mop drying unit according to the second embodiment of the present invention can exhaust air of the receiving space (S) to the external space of the housing (110) through the air discharge path. In addition, the mop (242) of the robot cleaner (200) in the second embodiment of the present invention can be arranged between the external air supply module and the exhaust fan. That is, since the external air supply module is arranged in the rear space of the joining wall (123) and the exhaust fan is arranged in the side wall (124), the mop of the robot cleaner (200) can be arranged on a straight line connecting the external air supply module and the exhaust fan.

[0464] Meanwhile, in the second embodiment of the present invention, a guide member that guides air away from the outer wall (111) of the housing (110) may be arranged at the outlet of the steam discharge passage. The direction away from the outer wall (111) of the housing (110) may mean the direction toward the front center of the housing (110). For example, the guide member may guide the heat discharged through the outlet of the steam discharge passage toward the bottom member (121).

[0465] When the robot cleaner station (100) according to the present invention is placed in the installation space (24) of the kitchen cabinet (2), the outer wall (111) of the housing (110) may come into contact with the mop holder (26) of the kitchen cabinet (2). At this time, since the mop holder (26) has a characteristic of being vulnerable to moisture, if the heat discharged from the steam discharge passage flows toward the outer wall (111) of the housing (110), the mop holder (26) may be damaged. Therefore, if a guide member that guides the heat discharged in a direction away from the outer wall (111) of the housing (110) is installed at the discharge port of the steam discharge passage according to the second embodiment of the present invention, damage to the mop holder (26) can be prevented.

[0466] In a second embodiment of the present invention, the guide member may be a vane or louvering that guides the heat discharged through the discharge port of the steam discharge channel in one direction. The guide member may guide the heat discharged through the discharge port of the steam discharge channel toward the inside of the housing (110). The heat discharged to the outside of the housing (110) through the discharge port of the steam discharge channel may flow away from the inner wall surface of the kitchen cabinet (2) by the guide member.

[0467] The heat discharged outside the housing (110) through the outlet of the steam discharge passage can flow in a direction away from the outer wall (111) of the housing (110) by the guide member. For example, the heat discharged outside the housing (110) through the outlet of the steam discharge passage can flow in a direction toward the bottom member (121).

[0468]

[0469] FIG. 34 is a plan view for explaining a mop drying unit of a robot cleaner station according to a third embodiment of the present invention, FIG. 35 is a perspective view for showing a state in which an upper cover is removed from a robot cleaner station according to a third embodiment of the present invention, FIGS. 36 and 37 are drawings for showing a state in which air flows into a robot cleaner station according to a third embodiment of the present invention, FIG. 38 is a lower perspective view for showing an air exhaust port of a robot cleaner station according to a third embodiment of the present invention, and FIG. 39 is an enlarged view for showing a part of an air exhaust unit of a robot cleaner station according to a third embodiment of the present invention.

[0470] Hereinafter, with reference to FIGS. 34 to 39, the mop drying unit of the robot cleaner station according to the third embodiment of the present invention will be described.

[0471] Meanwhile, in order to avoid duplicate explanation, except for what is specifically mentioned in the third embodiment of the present invention, other configurations may be based on the contents of the mop drying unit (170) according to the first embodiment of the present invention.

[0472] The mop drying unit (170) of the robot cleaner station (100) according to the third embodiment of the present invention may include an external air supply module (171) and an air exhaust unit (2172).

[0473] The outside air supply module (171) can heat the air outside the housing (110) and supply it to the receiving space (S). The outside air supply module (171) can include an outside air supply path (171a), an outside air inlet (171b), an outside air discharge portion (171c), a heater (171d), and a blower fan (not shown).

[0474] An external air advanced path (171a) is formed in the external air supply module (171). The external air supply path (171a) can flow external air to the external air discharge unit (171c).

[0475] The external air supply path (171a) can connect the external space of the housing (110) and the receiving space (S). One side of the external air supply path (171a) can be connected to the external space through the external air inlet (171b), and the other side of the external air supply path (171a) can be connected to the receiving space (S) through the external air discharge portion (171c).

[0476] An external air inlet (171b) may be formed on the rear surface of the housing (110). A plurality of external air inlets (171b) may be formed on the rear surface of the housing (110). Air outside the housing (110) may be introduced into the external air supply path (171a) through the external air inlet (171b). Accordingly, air outside the housing (110) may be introduced into the interior of the housing (110).

[0477] At least a portion of the outside air discharge portion (171c) may be positioned above the washing plate (122). The outside air discharge portion (171c) may be opened in a direction facing the washing plate (122). A pair of outside air discharge portions (171c) may be provided in a state in which they are opened downward.

[0478] The outside air discharge unit (171c) can discharge air that has passed through the outside air supply passage (171a). The outside air discharge unit (171c) can discharge air heated by the heater (171d). For example, an outside air discharge port may be formed in the outside air discharge unit (171c).

[0479] Meanwhile, in the present embodiment, the left-right diameter of the outside air discharge unit (171c) may become narrower as it moves forward. That is, in the present embodiment, the left-right diameter of the outside air discharge unit (2171c) may have a width at the rear end that is greater than a width at the front end. Through this, even if the disc-shaped mop (242) is rotated during the drying process, there is an effect of being able to dry the entire mop (242) evenly.

[0480] Meanwhile, the external air discharge unit (171c) may be equipped with a grille that guides the direction of air discharge. This can prevent heated air from being discharged in a concentrated manner to a specific location.

[0481] With the mop (242) secured to the cleaning plate (122), the outside air discharge portion (171c) can be opened toward the upper side of the mop (242). Accordingly, the outside air discharge portion (171c) is positioned adjacent to the mop (242) and opens downward, so that air discharged from the outside air discharge portion (171c) can flow toward the mop (242).

[0482] In particular, the external air discharge unit (171c) of the present embodiment may be provided in a form that slopes downward as it goes toward the front of the robot cleaner station (100). Accordingly, the end from which air is discharged from the external air discharge unit (171c) may be formed to be inclined at a predetermined angle with respect to the ground. At this time, the angle may be 90 degrees or less. Accordingly, the external air discharge unit (171c) may discharge air along a direction intersecting the direction in which the flow guide surface (122c) is formed.

[0483] A blower fan (not shown) is placed on the outside air supply path (171a) and can blow air toward the receiving space (S). When the blower fan (not shown) is driven, air drawn in through the outside air inlet (171b) can be heated by the heater (171d) and discharged to the receiving space (S) through the outside air discharge portion (171c).

[0484] The heater (171d) is placed on the outside air supply passage (171a) and can heat the air flowing through the outside air supply passage (171a). The heater (171d) can heat the air discharged through the outside air discharge portion (171c).

[0485] The heater (171d) may include a heater housing and a heating element. At this time, the heater housing may be placed on an external air supply path (171a), and a space may be provided therein in which the heating element can be accommodated. In addition, the heating element may heat air flowing into the heater housing. Accordingly, air heated by the heating element may be discharged into the accommodation space (S) through the external air discharge portion (171c) to dry the wet mop (242).

[0486]

[0487] In this embodiment, air heated by heat discharged from the external air supply module (171) can be discharged through the air discharge unit (2172).

[0488] The air exhaust unit (2172) may be positioned at least partially above the receiving space (S).

[0489] The air heated by the heat discharged from the outside air supply module (171) can supply heat to the mop (242) of the robot cleaner (200). Accordingly, the moisture absorbed and remaining in the mop (242) can absorb heat from the air and vaporize. The vaporized moisture can flow in the receiving space (S). Accordingly, the air in the receiving space (S) can contain vaporized moisture, and the humidity in the receiving space (S) can increase (hereinafter, the air containing vaporized moisture in the receiving space (S) can be referred to as 'moisture vapor').

[0490] Specifically, at least a portion of the air exhaust portion (2172) may be disposed on the upper cover (113), and the upper cover (113) may cover the upper portion of the receiving space (S).

[0491] The air heated by the heat discharged from the outside air supply module (171) vaporizes the moisture in the mop (242), resulting in increased humidity. Therefore, when the robot cleaner station (100) is placed at the bottom of the kitchen cabinet (2), if the moisture vapor comes into contact with various parts of the kitchen cabinet (2), such as the mop holder (26), it will have a negative effect on the parts.

[0492] At this time, in this embodiment, the upper cover (113) covers the upper part of the receiving space (S), and the door (126) covers the front of the receiving space (S), so that the upper cover (113) together with the door (126) prevents the moisture vapor of the receiving space (S) from escaping to the outside, thereby preventing the kitchen cabinet (2) from coming into contact with the moisture vapor.

[0493] The air exhaust unit (2172) may include an air intake (2172a), an air exhaust duct (2172b), and an exhaust fan (2172c).

[0494] The air intake (2172a) may be connected to the receiving space (S). The air intake (2172a) may be positioned at the upper side of the receiving space (S). The wet vapor in the receiving space (S) may be discharged through the air intake (2172a).

[0495] The air intake (2172a) can be positioned higher from the ground than the robot cleaner (200) when the robot cleaner (200) is mounted on the mounting portion (120). This can increase the efficiency of inhaling steam that rises as the mop dries.

[0496] For example, an air intake port (2172a) may be formed in the upper cover (113). At this time, the upper cover (113) may include a cover portion covering the receiving space (S) and a duct portion coupled to the cover portion to form a flow path. At this time, an air intake port (2172a) may be formed in the duct portion to form an air exhaust duct (2172b).

[0497] As another example, the air intake (2172a) may be formed on an air exhaust duct (2182b) in the shape of a circular or square pipe, and the air exhaust duct (2172b) may be coupled to the upper cover (113).

[0498] With this configuration, when the upper cover (113) is separated, the air exhaust duct (2172b) can be separated together with the upper cover (133), and when it is necessary to open the upper part of the robot cleaner station (100) for reasons such as repair, there is an advantage in that the worker can remove the air exhaust duct (2172b) with a simple action of lifting the upper cover (113).

[0499] The air intake port (2172a) may be formed in the form of a hole on the air exhaust duct (2172b). For example, the air intake port (2172a) may be formed in the form of a plurality of slits formed in parallel on the air exhaust duct (2172b). Alternatively, the air intake port (2172a) may be formed in the form of a long hole on the air exhaust duct (2172b).

[0500] Meanwhile, a plurality of air intake ports (2172a) may be arranged at the same distance from the front end of the housing (110). For example, a pair of air intake ports (2172a) may be arranged at the same distance from the front end of the housing (110). That is, the air intake ports (2172a) may include a first intake port and a second intake port. At this time, the first intake port may be arranged at the upper left side in front of the receiving space (S), and the second intake port may be arranged spaced apart from the first intake port and at the upper right side in front of the receiving space (S). In this case, the distance from the first intake port to the first outer wall member (111a) and the distance from the second intake port to the second outer wall member (111b) may be smaller than the distance between the first intake port and the second intake port.

[0501]

[0502] The distance from the outside air outlet (171c) to the air intake (2172a) may be greater than the distance from the outside air outlet (171c) to the mop (242). This is to prevent the heated air discharged from the outside air outlet (171c) from being sufficiently supplied to the mop (242) and being directly sucked into the air intake (2172a), thereby wasting energy.

[0503] In addition, the air intake port (2172a) may be arranged closer to the door (126) than the outside air outlet port (171c). Since the air intake port (2172a) is arranged at the upper front portion of the receiving space (S), the range of space in which the heat discharged from the outside air outlet (171c) flows is expanded, so that the drying efficiency of the mop (242) can be improved. Accordingly, the heat discharged through the outside air outlet (171c) can flow forward and dry the mop (242) of the robot cleaner (200), and then be discharged through the air intake port (2172a).

[0504] Additionally, the air intake (2172a) may be positioned above the path along which the robot cleaner (200) moves within the housing (110). This can prevent condensation from forming on the walls within the housing (110).

[0505] For example, at least a portion of the air intake (2172a) may be positioned vertically above a position where the left-right width of the robot cleaner (200) is greatest when the robot cleaner (200) is mounted on the mounting portion (120). That is, at least a portion of the air intake (2172a) may be positioned above a position where the gap between the robot cleaner (200) and a pair of side walls (124) is the narrowest. At this time, at least a portion of the air intake (2172a) may be positioned in front of the cleaning plate (122).

[0506] Through this, it is possible to prevent steam generated during the drying process of the mop (242) from flowing forward of the robot cleaner station (100), and to prevent moisture from penetrating into the sensor placed in front of the robot cleaner (200) and causing malfunction.

[0507] The air exhaust duct (2172b) can connect the air intake (2172a) and the exhaust fan (2172c) to the drain pipe (25) of the kitchen cabinet (2). The air exhaust duct (2172b) can guide the moisture vapor discharged through the air intake (2172a) to the drain pipe (25).

[0508] The air exhaust duct (2172b) is connected to an exhaust fan (2172c) on one side, but can branch into multiple branches on the other side. This allows for the suction of moisture from multiple locations even when using a single exhaust fan (2172c), thereby achieving the effect of stably discharging moisture.

[0509] An air exhaust duct (2172b) may have an air exhaust path formed therein that communicates with an air intake port (2172a).

[0510] The air exhaust path may refer to a path through which air drawn in through the air intake port (2172a) flows. For example, the air exhaust path may be formed by including the internal space of the air exhaust duct (2172b), the internal space of the exhaust fan housing (to be described later), and the internal space of the check valve (to be described later). One side of the air exhaust path may be connected to the air intake port (2172a), and the other side may be connected to the air exhaust port (2172d).

[0511] The exhaust fan (2172c) can cause air flow from the air intake port (2172a) to the exhaust pipe (25). The exhaust fan (2172c) can generate air flow so that the moisture vapor in the receiving space (S) can be sucked into the air intake port (2172a) and then discharged to the outside through the air discharge duct (2172b).

[0512] The exhaust fan (2172c) may include an exhaust fan housing, a fan motor, and an impeller. At this time, the exhaust fan motor and the exhaust fan impeller may be accommodated inside the exhaust fan housing. The exhaust fan housing may have a flow path formed therein so as to communicate with an air discharge duct (2172b). Accordingly, when the exhaust fan motor is operated and the exhaust fan impeller rotates, air in the accommodation space (S) or the housing (110) may be introduced into the air discharge duct (2172b), pass through the inside of the exhaust fan housing, and be discharged through the air outlet (2172d).

[0513] Meanwhile, in the present embodiment, the exhaust fan (2172c) may be coupled with the outside air supply module (171). Specifically, the exhaust fan housing of the exhaust fan (2172c) may be coupled with the outside air supply module (171) to form a single assembly. This allows the space occupied by the outside air supply module (171) and the air exhaust unit (2172) to be minimized.

[0514] The exhaust fan (2172c) may be placed on the left and right sides of the outside air supply module (171). Specifically, the exhaust fan (2172c) may be placed between the dust collection motor (152) and the outside air supply module (171). This allows components to be placed in a limited space, and secures space for arranging a passage for discharging steam.

[0515] The mop drying unit (170) may include a check valve that prevents the fluid inside the drain pipe (25) from flowing back into the air exhaust duct (2172b). The check valve may be positioned at the rear of the exhaust fan (2172c). The check valve may be in communication with the internal space of the exhaust fan (2172c). That is, based on the air flow direction, the check valve may be positioned downstream of the exhaust fan (2172c). An air exhaust port (2172d) may be formed at the rear end of the check valve.

[0516] At this time, the lower end of the air outlet (2172d) may be positioned perpendicular to the ground. Specifically, the air outlet (2172d) may be formed in an air discharge pipe positioned perpendicular to the ground, and the air discharge pipe may be connected to a check valve. This configuration is intended to prevent the fluid discharged from the air outlet (2172d) from flowing backward by utilizing the upward convection property of high-temperature, humid air.

[0517] The air discharge unit (2172) may be connected downstream of the drain trap (25a) of the drain pipe (25). Specifically, the air discharge port (2172d) of the air discharge unit (2172) may be connected to the drain pipe (25) via a flow path member. For example, the flow path member may be a hose.

[0518] The wet steam discharged through the air intake (2172a) and passed through the exhaust fan (2172c) can be discharged to the outside of the housing (110) along the duct member while passing through the air outlet (2172d).

[0519] At this time, the flow path member can be connected to the drain pipe (25) by penetrating the first outer wall member (111a). Alternatively, the flow path member can be connected to the drain pipe (25) by penetrating the second outer wall member (111b). With this configuration, the connection direction of the flow path member can be selected depending on the installation environment of the robot cleaner station (100) of the present invention, thereby providing the advantage of easy installation and management.

[0520]

[0521] Meanwhile, the robot cleaner station (100) according to the fourth embodiment of the present invention may include a mop drying unit (170).

[0522] Meanwhile, in order to avoid duplicate explanation, except for what is specifically mentioned in the fourth embodiment of the present invention, other configurations may be based on the contents of the mop drying unit (170) according to the third embodiment of the present invention.

[0523] The mop drying unit of the robot cleaner station (100) according to the fourth embodiment of the present invention may include an external air supply module (171) and an air exhaust unit (2172).

[0524] Air heated by heat discharged from the outside air supply module (171) can be discharged through the air discharge unit (2172).

[0525] The air exhaust unit (2172) may be positioned at least partially above the receiving space (S).

[0526] The air heated by the heat discharged from the outside air supply module (171) can supply heat to the mop (242) of the robot cleaner (200). Accordingly, the moisture absorbed and remaining in the mop (242) can absorb heat from the air and vaporize. The vaporized moisture can flow in the receiving space (S). Accordingly, the air in the receiving space (S) can contain vaporized moisture, and the humidity in the receiving space (S) can increase (hereinafter, the air containing vaporized moisture in the receiving space (S) can be referred to as 'moisture vapor').

[0527] At this time, in the present embodiment, the air (wet steam) introduced into the air intake port (2172a) can be re-supplied to the outside air supply module. That is, the wet steam introduced into the air intake port (2172a) can be introduced into the outside air supply module (171) again through the air discharge port (2172). The wet steam introduced into the outside air supply module (171) can be heated again by the heater (171d) to lower its relative humidity, and can be discharged again into the receiving space (S) by the blower fan (not shown).

[0528] Specifically, at least a portion of the air exhaust portion (2172) may be disposed on the upper cover (113), and the upper cover (113) may cover the upper portion of the receiving space (S).

[0529] The air exhaust unit (2172) may include an air intake (2172a), an air exhaust duct (2172b), and an exhaust fan (2172c).

[0530] The air intake (2172a) may be connected to the receiving space (S). The air intake (2172a) may be positioned at the front upper side of the receiving space (S). The wet vapor in the receiving space (S) may be discharged through the air intake (2172a).

[0531] The air exhaust duct (2172b) can connect the air intake (2172a) and the outside air supply module (171). The air exhaust duct (2172b) can guide the moisture vapor discharged through the air intake (2172a) to the outside air supply module (171).

[0532] The exhaust fan (2172c) can cause air to flow from the air intake port (2172a) toward the outside air supply module (171). Specifically, the exhaust fan (2172c) can cause air to flow so that moisture vapor in the receiving space (S) can be sucked into the air intake port (2172a) and then flowed to the heater (171d) through the air discharge duct (2172b).

[0533] The outside air supply module (171) may include an outside air inlet (171b) through which air from outside the housing (110) is drawn in, an outside air discharge unit (171c) for discharging air into a receiving space (S), an outside air supply path (171a) connecting the outside air inlet (171b) and the outside air discharge unit (171c), a blower fan (not shown) disposed on the outside air supply path (171a) for blowing air into the receiving space (S), and a heater (171d) for heating air flowing through the outside air supply path (171a).

[0534] The temperature of the heat heated by the heater (171d) and discharged to the receiving space (S) may be 65 degrees Celsius or higher.

[0535] The air exhaust duct (2172b) may be in communication with the outside air supply path (171a). Alternatively, the air exhaust duct (2172b) may be in communication with a heater housing in which a heater (171d) is arranged.

[0536] The wet steam in the receiving space (S) introduced through the air intake (2172a) can be introduced into the outside air supply path (171a) or heater housing (171da) through the air discharge duct (2172b), and the wet steam can be discharged into the receiving space (S) after being heated by the heater (171d).

[0537] Meanwhile, the robot cleaner station (100) according to the fourth embodiment of the present invention may further include a door (126).

[0538] The door (126) is rotatably arranged in the housing (110) and can open and close the receiving space (S).

[0539] The air heated by the heat discharged from the outside air supply module (171) is in a state of wet steam containing the moisture of the mop (242). Therefore, when the robot cleaner station (100) is placed at the bottom of the kitchen cabinet (2), if the wet steam comes into contact with various parts of the kitchen cabinet (2), such as the mop holder (26), it will have a negative effect on the parts.

[0540] The door (126) covers the front of the receiving space (S), thereby preventing the moisture vapor in the receiving space (S) from escaping to the outside, thereby preventing the kitchen cabinet (2) from coming into contact with the moisture vapor.

[0541] Accordingly, the outside air supply module (171) can discharge heat while the door (126) closes the receiving space (S). Since the heater (171d) of the outside air supply module (171) is operated while the door (126) closes the receiving space (S), the moisture vapor generated while drying the mop (242) may not be discharged to the outside. Accordingly, the temperature of the space where the robot cleaner (200) is accommodated can be increased to dry the mop (242).

[0542] When the humidity of the receiving space (S) is higher than a threshold value (hereinafter, referred to as “reference humidity”), the door (126) can open the receiving space (S). The reference humidity may refer to a humidity value at which moisture contained in the air of the receiving space (S) is saturated. When the humidity of the receiving space (S) is higher than the threshold value, it is difficult for the air of the receiving space (S) to absorb the moisture of the mop (242), so the door (126) can be opened to discharge a portion of the air of the receiving space (S) to the outside. Through this, the humidity of the receiving space (S) can be prevented from increasing excessively.

[0543] When the humidity in the receiving space (S) drops below a threshold value, the door (126) closes again, and the outside air supply module (171) can discharge heat back into the receiving space (S).

[0544] Meanwhile, the mop drying unit (170) of the robot cleaner station (100) according to the fourth embodiment of the present invention may further include an exhaust fan (2172c).

[0545] The exhaust fan (2172c) can cause a flow of air from the air intake (2172a) toward the outside air supply module (171).

[0546] When the humidity of the receiving space (S) is higher than a threshold value (hereinafter, referred to as “exhaust humidity”), the exhaust fan (2172c) may be driven. The exhaust humidity may refer to a humidity value at which moisture contained in the air of the receiving space (S) is saturated. When the humidity of the receiving space (S) is higher than the threshold value, it is difficult for the air of the receiving space (S) to absorb the moisture of the mop (242), so the exhaust fan (2172c) may be driven so that the air of the receiving space (S) may be introduced into the air intake (2172a).

[0547] When the humidity in the receiving space (S) drops below a threshold value, the operation of the exhaust fan (2172c) is stopped, and the outside air supply module (171) can discharge heat back into the receiving space (S).

[0548] Meanwhile, in the robot cleaner station (100) according to the fourth embodiment of the present invention, after drying of the mop (242) is completely completed, the door (126) is completely opened so that the wet steam in the receiving space (S) can be discharged to the outside, or the exhaust fan (2172c) is driven so that the wet steam in the receiving space (S) can be discharged through the air intake (2172a).
