Description

Robot vacuum station

The present invention relates to a robot cleaner station, and more specifically, to a built-in robot cleaner station which, 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.

With the recent advancement of industrial technology, robot vacuum cleaners are being developed that can move around and clean areas that require cleaning without user intervention.

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 clean the floor, and can move while sucking up dust on the floor in the space recognized by the sensor and wiping it with a mop, etc.

Among robot cleaners, there are dry robot cleaners that can suck up and remove foreign substances scattered on the floor, and wet robot cleaners that can wipe the floor with a moist mop to effectively remove foreign substances attached to the floor. Dry robot cleaners are equipped with a dust bin and suck up foreign substances on the floor with the suction power of a suction motor. Wet robot cleaners are equipped with a water tank and are configured so that the water contained in the water tank is supplied to a mop so that the mop wipes the floor in a moist state to effectively remove foreign substances attached to the floor. In addition, there are robot cleaners that are equipped with both an agitator and a mop.

The charging base of a robot vacuum cleaner is a device that supplies power to the battery of the robot vacuum cleaner to charge the battery by docking the robot vacuum cleaner that has finished cleaning. The charging base has a power supply module inside. The charging base 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 come into contact, power is supplied to the battery and it is charged.

Meanwhile, if the robot vacuum cleaner charging station is placed inside a building, it will occupy a certain area of the indoor space. In this case, the indoor space efficiency may be reduced. In addition, when a user or pet passes by, the robot vacuum cleaner may collide with the user or pet, causing injury to the user or pet, as well as damage to the robot vacuum cleaner.

In addition, in the case of stations with added dust collection functions for robot vacuum cleaners, there is a limit to the damage they can cause to the interior of a room due to the increased volume they occupy.

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.

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.

In this arrangement, the height of the overall cleaner station increases, so there is a limitation on how it can be installed using the space underneath the furniture, including the sink.

In addition, since the above-mentioned cleaner station must be installed at the bottom of the washing machine, a space for installing the washing machine must be provided, and there is a limitation that an installation space with a height exceeding the height of the cleaner station must be provided, considering not only the height of the washing machine itself.

Meanwhile, the above-mentioned vacuum cleaner station collects dust from the vacuum cleaner's dust bin into a dust bag placed on the side and then discharges it into the rear space of the vacuum cleaner station.

However, the lower space of the kitchen cabinet is usually blocked by a mop holder, etc., so it is difficult to clean it frequently. Accordingly, a lot of dust may accumulate in the lower space of the kitchen cabinet.

Additionally, since the kitchen cabinets are equipped with water and sewer pipes, the surrounding humidity is likely to be high, while the outer edges may be blocked by mop holders, etc.

In this situation, if the air exhausted from the dust collector motor is exhausted to the lower space of the kitchen cabinet, there is a limit to the dust being scattered and spread indoors.

In addition, since the heated air from the operation of the dust collector motor fills the lower part of the kitchen cabinet, the temperature at the lower part of the kitchen cabinet may rise, and there is a limit to the possibility that the lower space of the kitchen cabinet may become hot and humid, causing contamination.

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

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

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

In addition, the purpose is to provide a robot cleaner station that can make the overall size compact by arranging the path required for dust collection within a limited height and left-right space.

In addition, the purpose is to provide a robot cleaner station that prevents damage to the interior of a kitchen cabinet by sucking the heat discharged from a dust collection motor into the suction part of a robot cleaner so that high temperature air does not accumulate inside the kitchen cabinet.

In addition, when a robot cleaner is combined, the purpose is to provide a robot cleaner station capable of automatically washing the mop of the robot cleaner by a mop washing unit.

In addition, the purpose is to provide a robot cleaner station that washes mops using the kitchen water pipe and drain pipe, so that the user does not need to separately inject water or discharge waste water.

In addition, the purpose is to provide a robot cleaner station that can automatically dry the mop by supplying hot air to the mop after washing the mop of the robot cleaner.

In order to achieve the above-mentioned purpose, the robot cleaner station according to the present invention can maximize space efficiency by stacking a plurality of paths required for dust collection in the vertical direction.

Specifically, a robot cleaner station according to the present invention comprises: a housing; a mounting portion disposed in the housing, to which at least a portion of a robot cleaner is coupled; and a dust collection portion for collecting dust inside a dust bin of the robot cleaner; wherein the dust collection portion comprises: a dust collection portion housing into which dust inside the dust bin is introduced; a dust collection motor providing a suction force for sucking dust inside the dust bin; a dust collection motor housing in which the dust collection motor is accommodated; a first dust collection passage connecting a space inside the dust bin and an internal space of the dust collection portion housing; and a second dust collection passage connecting the internal space of the dust collection portion housing and the internal space of the dust collection motor housing; wherein at least a portion of the first dust collection passage is disposed above the second dust collection passage.

At this time, the first dust collection path can be formed along a direction intersecting the vertical direction.

Additionally, the second dust collection path can be formed along a direction intersecting the vertical direction.

This allows multiple filaments to be arranged close to the horizontal direction to reduce the overall height, while stacking them to maximize space efficiency.

Additionally, the first dust collecting path can be bent at least once.

Meanwhile, the dust collecting motor housing can be placed at the rear of the dust collecting unit housing.

In addition, a dust passage hole that is connected to the first dust collection path and through which dust inside the dust bin flows in may be arranged at the rear of the dust collection unit housing.

Additionally, the dust collecting motor housing may be positioned rearward of the first dust collecting path.

That is, based on the front-back direction, the dust collector housing may be positioned at the frontmost position, and the first dust collector passage and the second dust collector passage may be positioned at the rear of the dust collector housing. In addition, the dust passage hole may be positioned at the rear of the first dust collector passage, and the dust collector motor housing may be positioned at the rear of the second dust collector passage. In addition, the dust collector motor housing may be positioned at the rear of the dust passage hole.

Accordingly, the dust collection unit is arranged along the front-back direction, which has the effect of lowering the overall height of the robot cleaner station.

To this end, the dust collector housing is formed with an inlet port communicating with the first dust collector passage and an outlet port communicating with the second dust collector passage, and the inlet port of the dust collector housing can be positioned above the outlet port of the dust collector housing.

In addition, the first dust collection path and the second dust collection path may be formed to pass through the same surface of the dust collection unit housing. That is, the first dust collection path and the second dust collection path may be formed to pass through the rear surface of the dust collection unit housing.

Meanwhile, the first dust collection path and the second dust collection path may be formed on different surfaces of the dust collection unit housing. That is, the first dust collection path may be formed on the rear surface of the dust collection unit housing, and the second dust collection path may be formed along the lower surface of the dust collection unit housing.

Meanwhile, the discharge port of the dust collecting unit housing may be positioned in front of the inlet port of the dust collecting unit housing. Through this, dust and air flowing in from the inlet port can be sufficiently distributed and stored throughout the dust bag. Accordingly, dust can be prevented from being concentrated and accumulated in a specific location of the dust bag.

Meanwhile, the flow directions of the air flowing through the first dust collection path and the air flowing through the second dust collection path may be different from each other. That is, the air flowing through the first dust collection path may flow from the rear to the front of the robot cleaner station, and the air flowing through the second dust collection path may flow from the front to the rear of the robot cleaner station.

Meanwhile, the robot cleaner station of the present invention may further include a circulating flow path that is connected to the internal space of the dust collecting motor housing and through which air discharged from the dust collecting motor flows.

At this time, at least a portion of the reflux path may be positioned lower than the first dust collection path.

Additionally, at least a portion of the reflux path may be positioned on the lower side of the robot cleaner.

In addition, the mounting portion of the present invention further includes a base with which the wheel of the robot cleaner comes into contact, and at least a portion of the reflux path can pass through the lower side of the base.

Through this, air drawn into the dust bin of the robot cleaner can pass through the first dust collection path and the second dust collection path, and then be discharged back to the robot cleaner through the return path.

Meanwhile, the dust collection unit is arranged between the housing and the mounting unit, and the dust collection unit can be arranged on one side of the mounting unit in the left and right directions. Through this, components necessary for dust collection can be arranged despite the height restriction.

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

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.

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

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.

In addition, the purpose is to provide a robot cleaner station that can make the overall size compact by arranging the path required for dust collection within a limited height and left-right space.

In addition, it has the effect of preventing damage to the interior of the kitchen cabinet by sucking the heat discharged from the dust collection motor into the suction part of the robot vacuum cleaner to prevent high temperature air from entering the interior of the kitchen cabinet.

In addition, when a robot vacuum cleaner is combined, the robot vacuum cleaner's mop can be automatically washed, reducing the hassle of having to detach the mop and wash it separately.

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

In addition, since the mop is washed using the kitchen water pipe and drain pipe, it reduces the hassle of the user having to separately pour in water or drain waste water.

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 a wet mop.

Kitchen cabinets and vacuum cleaner system

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.

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 provide a space for cooking food or washing dishes.

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

For example, the kitchen cabinet (2) may include a sink that provides a space for washing dishes on the countertop. Or, the kitchen cabinet (2) may include a cooking surface on which cooking operations are performed. In addition, the kitchen cabinet (2) may include a gas range on which a gas range, induction, highlight, or oven is installed on the countertop.

In general, kitchen cabinets (2) can be made of a standard cabinet with a width of 600 mm in the front-back direction and a width of 600 mm in the left-right direction.

A cleaner 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 mean a path connected to an external water source that supplies fluid to the structure, and the drain pipe may mean a path that discharges fluid discharged from the structure into a sewer.

A storage space for storing dishes and kitchen tools, etc., may be provided at the lower part 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, if the kitchen cabinet (2) is a sink, a sink (22a) may be arranged on the top plate (22).

In addition, the lower plate (23) can be supported by a pedestal (21). The pedestal (21) is arranged along a direction perpendicular to the floor of the kitchen and can support the load of the kitchen cabinet (2). At this time, a space can be formed between the floor of the kitchen and the lower plate (23) depending on the height of the pedestal (21).

The robot cleaner station (100) can dry the rotating cleaning unit (240) of the robot cleaner (200). The robot cleaner station (100) can supply power to the robot cleaner (200).

Robot vacuum cleaner

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

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

A robot vacuum cleaner (200) can automatically clean an area to be cleaned by driving around the area to be cleaned and sucking up foreign substances such as dust from the floor.

The robot cleaner (200) according to the 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 by determining the up-down direction based on the state in which the robot cleaner (200) is placed on the floor.

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.

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.

A robot 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).

The body (210) can form the overall appearance 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).

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

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 larger 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 provide a structure that is advantageous in avoiding obstacles when the robot cleaner (200) moves (drives).

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

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.

The lower body can be joined to the upper body to form a space capable of accommodating a battery, at least one sensor, and at least one motor therein.

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

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).

Meanwhile, the lower body may be further 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 the exhaust port. At this time, a filter may be placed in the exhaust port.

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.

An agitator (250) to 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 sucking dust.

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

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).

The bumper may be coupled along a part 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 relative to the center of the body (210), the bumper can return to its original position by the restoring force of the elastic member (not shown), and can absorb or disperse the shock applied to the bumper, thereby preventing and reducing the shock from being transmitted to the body (210).

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

The dust bin (220) can store dust that is introduced through the suction path. The dust bin (220) can be formed with a dust inlet that is connected to the suction path, an internal space that can store dust, and an air outlet through which air can be discharged.

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.

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) and 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.

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).

In addition, the robot cleaner (200) according to the embodiment of the present invention may be provided with a dust bin door (222) that can selectively open and close the dust discharge port (221). Specifically, the dust bin door (222) may be coupled to the body (210) and positioned so as to block the dust discharge port (221). For example, the dust bin door (222) may be formed of a rubber or resin material and provided so as to be flippable, so that one side may be fixedly coupled to the body (210).

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

The water tank (230) is formed in the form of a container having an internal space to store a liquid such as water therein. 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).

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

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).

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.

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) or on the rotating plates, respectively, so that the liquid inside the water tank (230) can be supplied to each of the pair of mops (242).

That is, the nozzle (not shown) may be formed in the form of a single pipe branching into two, and at this time, one of the branched ends may be located above the left mop, and the other branched end may be located above the right mop.

Meanwhile, although not shown, the water tank (230) is equipped with a pump to flow water inside the water tank (230) 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).

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

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.

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

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

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

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

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 in a shape in which 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) can be parallel to the floor surface (B), or can be inclined with the floor surface (B).

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

Meanwhile, although not shown, the rotary cleaning unit (240) may be equipped with a driving unit that applies a rotational force to the rotary plate (241). For example, the driving unit may be equipped with 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.

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

Meanwhile, the agitator (250) according to the present embodiment receives rotational power from a separate agitator motor (not shown), 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 rotary cleaning unit (240).

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).

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

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.

The driving unit (not shown) may include a driving motor and a gear. At this time, the driving motor may be accommodated inside the body (210) and provide power to the wheel (260). The driving motor may include a first driving motor and a second driving motor.

The driving motor may be formed by an electric motor. A plurality of gears are configured to mesh with each other and rotate, connect the driving motor and the wheel (260), and transmit the rotational power of the driving motor to the wheel (260). Therefore, when the rotational axis of the driving motor rotates, the wheel (260) can rotate.

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.

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 guiding the movement of the robot cleaner (200).

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

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

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

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

Robot vacuum station

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.

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

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).

The robot vacuum station (100) may include a housing (110).

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

The housing (110) may have a space formed therein that can accommodate a mounting portion (120), a dust collection path (147, 148), a dust collection portion (140), a dust collection motor (145), a mop washing portion (160), a mop drying portion (170), and a reflux path.

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

The housing (110) includes a pair of outer walls (111) facing each other. The outer walls (111) may mean a surface formed along the direction of gravity.

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

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

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

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).

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

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.

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

Accordingly, the upper side of the housing (110) can be covered by the kitchen cabinet (2), and the lower side of the housing (110) can be covered by the kitchen floor. In addition, the left and right sides of the housing (110) are covered by the outer wall, but are placed at the lower part of the kitchen cabinet (2). At this time, the lower part of the kitchen cabinet (2) is finished by the baseboard (26) except for the robot cleaner station (100), so that as a result, only the front of the housing (110) can be exposed to the outside.

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

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.

Meanwhile, although not shown, a space through which a water supply hose connected to a water supply pipe passes through the housing (110), a space through which a drain hose passes through which waste water generated after washing the mop (242) is discharged, and a space through which a hose discharges moisture generated during the drying process of the mop (242) passes through may be formed. For example, a space through which the above hoses pass through may be formed in at least one of the outer wall (111) and the upper side (112) of the housing (110).

Joint

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

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

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

At this time, according to an embodiment, the fixing member (120) may be provided so as to be withdrawable from the housing (110) through a drawer (190).

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).

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).

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 mean a space formed upward along the vertical direction from the front end of the base (121) described later, and the upper end of the entrance may be the same as the lower surface of the lower side plate (23) of the kitchen cabinet (2) or the upper end of the housing (110).

In addition, the entrance (127) is formed so that the width in the left and right directions is greater than the maximum width of the robot cleaner (200). At this time, at least one of the dust collection unit (140) and the mop washing unit (160) may be arranged on the left and right sides of the entrance (127). Accordingly, the left and right ends of the entrance (127) may form a boundary with the dust collection unit (140) and the mop washing unit (160). If there is no dust collection unit (140) or mop washing unit (160), the outer wall surface of the housing (110) may also form a boundary.

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

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

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

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

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

The receiving space (S) of the mounting portion (120) may accommodate a robot cleaner (200). For example, the receiving space (S) may mean a space surrounded by a base (121), a joining wall (123), and an inner wall (124). As another example, the receiving space (S) may mean a space surrounded by a base (121), a washing plate (122), a joining wall (123), and an inner wall (124). As another example, the receiving space (S) may mean 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).

The base (121) can be positioned so that the robot cleaner station (100) is in contact with the floor, and is configured to support the robot cleaner (200) when the robot cleaner (200) is coupled to the robot cleaner station (100). The base (121) can have the upper surface come into contact with the wheel (260) of the robot cleaner (200). In addition, the base (121) can have the upper surface come into contact with the auxiliary wheel (270) of the robot cleaner (200).

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

The base body (121a) can form the overall appearance of the base (121). An inclined portion (121b), a wheel coupling portion (121c), an agitator receiving portion (121d), and a washing tank (128) can be arranged in the base body (121a).

The base body (121a) may be formed in a form in which the width (or diameter) in the horizontal direction (parallel to X and Y) is larger 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.

A reflux path may be provided inside the base body (121a). Accordingly, air discharged from the dust collecting motor (145) may flow through the reflux path formed inside the base body (121a) and be exhausted to the air reflux port (125b).

The slope (121b) can be placed at the entrance through which the robot cleaner (200) climbs from the base body (121a).

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 front 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).

A wheel guide part (121ba) may be provided on the slope part (121b).

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 drive 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 relative 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.

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

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 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 the inclined part (121b), it can drive while being stably supported by not only the wheel (260) but also the auxiliary wheel (270).

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

The wheel coupling part (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 determined to stop the robot cleaner (200) to be connected to the power supply terminal (123b) and/or a position determined to stop the dust bin (220) of the robot cleaner (200) to be connected to the dust passage hole (123a).

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

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

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

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

The recessed portion (121da) may be formed to be recessed in the base (121). The recessed portion (121da) may form an accommodation space in which at least a portion of the agitator (250) is accommodated. Through this, when the wheel (260) of the robot cleaner (200) is secured to the wheel coupling portion (121c), at least a portion of the agitator (250) may be accommodated in the accommodation space of the recessed portion (121da).

The accommodation space of the sunken part (121da) can be communicated with the accommodation space (S) of the settling part (120).

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

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

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

The joining wall (123) is configured to place the dust passage hole (123a), the power supply terminal (123b), and the water supply nozzle (123c) of the robot cleaner station (100). The joining wall (123) can spatially separate the receiving space (S) from the components of the robot cleaner station (100). The joining wall (123) can extend vertically from the rear side of the base (121). The joining wall (123) can be formed to correspond to the shape of the robot cleaner (200). For example, when the body (210) of the robot cleaner (200) has a cylindrical shape, the joining wall (123) can be formed in an arc shape having a predetermined radius. With this 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. In addition, the robot vacuum cleaner (200) can be stably supported.

A dust passage hole (123a) may be formed in the mounting portion (120) so that air from outside the housing (110) may be introduced into the interior. Specifically, a dust passage hole (123a) may be formed in the joining wall (123) so that air from outside the housing (110) may be introduced into the interior. At this time, the dust passage hole (123a) may be arranged at the rear of the dust collection housing (141) described later.

The dust passage hole (123a) may be communicated with the dust bin (220) of the robot cleaner (200). The dust passage hole (123a) may be communicated with the dust discharge port (221) of the dust bin (220) of the robot cleaner (200). The dust passage hole (123a) may be formed in the shape of a hole corresponding to the shape of the dust bin (220) so that dust in the dust bin (220) may be introduced into the dust collection unit (140). The dust passage hole (123a) may be formed corresponding to the shape of the dust discharge port (221) of the dust bin (220).

The dust passage hole (123a) can be formed to communicate with the dust collection path (147, 148). Air sucked into the dust passage hole (123a) can flow through the dust collection path (147, 148) and then be exhausted through the air return unit (125).

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

The power supply terminal (123b) can supply power to the robot cleaner (200) coupled to the mounting portion (120). The power supply terminal (123b) can be electrically connected by coming into contact with the charging terminal of the robot cleaner (200). The power supply terminal (123b) can be arranged in the mounting portion (120). Specifically, the power supply terminal (123b) can be arranged in the coupling wall (123). The power supply terminal (123b) can be electrically connected to the robot cleaner (200) coupled to the coupling wall (123). The power supply terminal (123b) can supply power to the battery of the robot cleaner (200) coupled to the coupling wall (123).

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

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).

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

Meanwhile, various parts such as a dust collection path (147, 148), a dust collection unit (140), a dust collection motor (145), a detergent container (163), and a waste container (164) can be arranged on the outside of the inner wall (124). Specifically, a dust collection unit (140), a detergent container (163), and a waste container (164) can be accommodated in the space between the inner wall (124) and the outer wall (111) of the housing (110).

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

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

The washing plate (122) may be a plate formed so that it slopes downwards toward the center.

Specifically, the cleaning plate (122) includes a flow guide surface (122c) formed in a curved shape. In addition, at least one passage hole (122b) through which a fluid can pass may be formed on the flow guide surface (122c). In addition, a cleaning protrusion (122a) may be formed to protrude on the flow guide surface (122c).

At this time, a pair of cleaning protrusions (122a) may be symmetrically formed on the flow guide surface (122c). Specifically, a pair of cleaning protrusions (122a) may be arranged on the vertical lower side of a pair of mops (242) of the robot cleaner (200), so as to face the pair of mops (242), and may be arranged so as to be able to come into contact with at least a part of the pair of mops (242).

And, the passage holes (122b) may be formed in multiple numbers on the flow guide surface (122c), and may be formed between a pair of cleaning protrusions (122a). For example, the passage holes (122b) may be formed in multiple numbers, including a position having the lowest height from the ground (the floor of the kitchen) among the flow guide surfaces (122c), and may be formed between a pair of cleaning protrusions (122a). Through this, the fluid discharged between the pair of cleaning protrusions (122a) may be guided to flow into the passage holes (122b).

Meanwhile, the height of the flow guide surface (122c) from the kitchen floor may increase as it goes rearward from the position where the passage hole (122b) is formed. That is, the height of the flow guide surface (122c) from the kitchen floor may increase as it gets closer to the outside air discharge unit (171c) described later.

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

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

The washing tank (128) is configured to have the washing plate (122) installed. The washing tank (128) can be placed on the rear side of the base body (121a). The washing tank (128) is placed on the lower side of the washing plate (122) and is detachably coupled with the washing plate (122). The washing tank (128) can be formed to correspond to the washing plate (122) so that the washing plate (122) can be inserted. Liquid that has passed through the washing plate (122) can flow into the washing tank (128).

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

Dust collection unit

FIGS. 12 to 16 illustrate drawings for explaining a dust collection unit of a robot cleaner station according to an embodiment of the present invention.

Referring to FIGS. 12 to 16 and FIG. 19, the dust collection unit (140) is described as follows.

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). That is, the dust collection unit (140) can be placed between the housing (110) and the mounting unit (120). For example, the dust collection unit (140) can be placed on one side in the left and right direction of the mounting unit (120). At this time, the receiving space (S) can be placed inside the mounting unit (120). Through this, components necessary for dust collection can be placed despite the height restriction.

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

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.

The dust collection housing (141) is connected to a dust bag drawer (144) so that a dust bag can be withdrawn therein, and a dust bag (not shown) can be stored inside the dust bag drawer (144). For example, the dust collection housing (141) is formed in a rectangular tube shape with an open front, and the rear internal space can be connected to the first dust collection path (147) and the second dust collection path (148).

Dust inside the dust bin (220) can enter the dust collection unit housing (141).

One side of the inside of the dust collector housing (141) may be connected to the first dust collector passage (147), and the other side may be connected to the second dust collector passage (148). In addition, when a dust bag (not shown) is combined with the dust collector housing (141), the dust bag (not shown) may be connected to the first dust collector passage (147) inside the dust collector housing (141).

Specifically, the dust collection unit housing (141) may be formed with an inlet (141a) communicating with a first dust collection path (147) and an outlet (141b) communicating with a second dust collection path (148).

At this time, the inlet (141a) may be positioned above the outlet (141b). As a result, the air and dust introduced through the inlet (141a) may flow downward, and the dust may be captured in a dust bag (not shown) and then discharged through the outlet (141b). In this process, since the air flows from the upper side to the lower side, there is an effect of preventing the air from flowing backwards upward or the dust from flying upward.

The dust bag (not shown) may mean a dust bag that collects dust sucked from the inside of the dust bin (220) of the robot cleaner (200) by the dust collecting motor (145). The dust bag (not shown) may be detachably coupled to the 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.

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

To this end, the dust bag (not shown) may be made of a material that allows air to pass through but does not allow foreign substances such as dust to pass through. For example, the dust bag (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 the volume increases.

The filter (142) may be placed between the dust collection unit housing (141) and the second dust collection path (148). The filter (142) may be placed at the discharge port (141b). The filter (142) may be a pre-filter or a HEPA filter. Air passing through the dust bag (not shown) may be introduced into the second dust collection path (148) through the filter (142).

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

At this time, referring to FIG. 19, the dust bag drawer (144) includes a dust bag drawer body (144a), a handle (144d), and a drawer rail (144e).

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 upper side, and an inlet (144b) and an outlet (144c) may be formed at the rear so as to be able to communicate with the first dust collection path (147) and the second dust collection path (148).

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 dust bag drawer body (144a) may be formed so that the upper left-right width is larger than the lower left-right width. That is, the interior of the dust bag drawer body (144a) may be formed to form a single section. Through this, the upper space where the dust bag (not shown) is provided can be maximized, and a path can be formed so that air passing through the dust bag (not shown) can easily escape to the lower section.

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

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

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 parts that are hinge-coupled to the front surface of the dust bag drawer body (144a), and a grip part formed by connecting the pair of connecting parts so that a user can grip it.

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

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).

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

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), the first dust collection path (147) and the second dust collection path (148) can be connected in the correct position to reduce flow loss.

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

Meanwhile, the dust collection unit (140) may further include a dust collection path (147, 148). The dust collection path may mean a path through which air sucked in through the dust passage hole (123a) flows through the dust bag to the dust collection motor (145).

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

The first dust collection path (147) can connect the dust bin (220) of the robot cleaner (200) and the internal space of the dust collection housing (141). The first dust collection path (147) can connect the dust passage hole (123a) of the mounting part (120) and the internal space of the dust collection housing (141). The first dust collection path (147) can mean a space between the dust bin (220) of the robot cleaner (200) and the dust collection housing (141). The first dust collection path (147) can be formed along a direction intersecting the vertical direction. For example, the first dust collection path (147) can be formed close to the horizontal direction. The first dust collection path (147) can be a space formed toward the rear from the dust passage hole (123a), and can be a path formed by bending toward the side from the dust passage hole (123a) so that dust and air can flow. Dust inside the dust bin (220) of the robot cleaner (200) can move into the internal space of the dust collection unit housing (141) through the first dust collection path (147).

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

At this time, in the present invention, the first dust collection path (147) and the second dust collection path (148) may be formed at different heights. That is, the first dust collection path (147) and the second dust collection path (148) may be arranged in a layered structure. At this time, the second dust collection path (148) may be arranged lower than the first dust collection path (147). That is, at least a portion of the first dust collection path (147) may be arranged above the second dust collection path (148).

With this configuration, multiple filaments can be arranged close to the horizontal direction to lower the overall height, while stacking them to minimize the left-right width and overall volume of the robot cleaner station (100).

Meanwhile, in the present embodiment, the first dust collection path (147) and the second dust collection path (148) may be formed to pass through the same surface of the dust collection unit housing (141). That is, the first dust collection path (147) and the second dust collection path (148) may be formed to pass through the rear surface of the dust collection unit housing (141).

That is, in this embodiment, air can be drawn in from the rear side of the dust collection unit housing (141) and then discharged to the rear side again.

By this arrangement, the flow directions of the air flowing through the first dust collection path (147) and the air flowing through the second dust collection path (148) can be different from each other. That is, the air flowing through the first dust collection path (147) can flow from the rear to the front, and the air flowing through the second dust collection path (148) can flow from the front to the rear.

Therefore, according to the present invention, the space occupied by the first dust collection path (147) and the space in the front-rear direction occupied by the second dust collection path (148) can be shared, and the overall space efficiency can be improved.

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

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

The dust collecting motor housing (146) may be placed inside the housing (110). The dust collecting motor housing (146) may accommodate the dust collecting motor (145) therein. The dust collecting motor housing (146) may be placed at the rear of the dust collecting unit housing (141). In addition, the dust collecting motor housing (146) may be placed at the rear of the first dust collecting passage (147). In addition, the dust collecting motor housing (146) may be placed at the rear of the second dust collecting passage (148).

That is, based on the front-back direction of the robot cleaner station (100), the dust collection housing (141) may be positioned at the frontmost position, and the first dust collection path (147) and the second dust collection path (148) may be positioned at the rear of the dust collection housing (141). In addition, the dust passage hole (123a) may be positioned at the rear of the first dust collection path (147), and the dust collection motor housing (146) may be positioned at the rear of the second dust collection path (148). In addition, the dust collection motor housing (146) may be positioned at the rear of the dust passage hole (123a).

Accordingly, the dust collection unit (140) is arranged along the entire front-rear direction of the robot cleaner station (100), which has the effect of lowering the overall height.

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

The internal space of the dust collecting motor housing (146) can be communicated with the reflux path. Accordingly, air passing through the dust collecting motor (145) can be guided to the reflux path.

The dust collecting motor (145) can generate suction force in the dust collecting path. That is, the dust collecting motor (145) can provide suction force to suck dust inside the dust bin (220) into the dust bag placed inside the dust collecting unit housing (141).

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

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

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

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

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

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

The air reflux unit (125) may be composed of a reflux path (125a) and an air reflux port (125b).

The reflux path (125a) can provide a path through which air discharged from the dust collecting motor (145) flows. The reflux path (125a) can be arranged inside the base body (121a). For example, the reflux path (125a) can be a space formed between the upper and lower surfaces of the base body (121a).

Accordingly, at least a portion of the reflux path (125a) can pass through the lower side of the base (121). In addition, at least a portion of the reflux path (125a) can be positioned lower than the robot cleaner (200) mounted on the upper side of the base body (121a).

Through this, the height of the robot cleaner station (100) can be prevented from increasing by forming a reflux path (125a) by utilizing the excess space inside the base (121), and space efficiency can be maximized because a separate space where the path is formed is not required.

The reflux path (125a) may be connected to the dust collecting motor (145) in a reflux manner. The reflux path may refer to a path connecting the internal space of the dust collecting motor housing (146) and the air reflux port (125b). One end of the reflux path (125a) may be connected to the internal space of the dust collecting motor housing (146), and the other end of the reflux path (125a) may be connected to the air reflux port (125b).

The reflux path (125a) may be a path formed along a direction intersecting the vertical direction. For example, the reflux path (125a) may be a path formed along a horizontal direction inside the housing (110).

At this time, at least a part of the reflux path (125a) may be arranged lower than the first dust collection path (147). That is, the reflux path (125a) may be arranged to pass through the lower side of the first dust collection path (147). Accordingly, the flow directions of the air flowing through the first dust collection path (147) and the air flowing through the reflux path (125a) may intersect each other on the horizontal plane.

Through this, the first dust collection path (147) and the reflux path (125a) can be arranged vertically (stacked) within a limited height to maximize space efficiency.

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

The air circulating port (125b) may be formed in the base (121). The air circulating port (125b) may be formed in the agitator receiving portion (121d). The air circulating port (125b) may be formed in the side wall of the recessed portion (121da). At this time, the suction portion (211) of the robot cleaner (200) may be arranged above the agitator receiving portion (121d). Accordingly, the circulating path (125a) may discharge air to the lower side of the suction portion (211), and the air passing through the circulating path (125a) may be introduced into the suction portion (211) arranged immediately above.

Therefore, the reflux path (125a) according to the embodiment of the present invention can guide the air discharged from the dust collecting motor (145) to the suction part (211) of the robot cleaner (200).

The reflux path (125a) can create a structure in which the air discharged from the dust collecting motor (145) is guided to the suction part (211) of the robot cleaner (200) instead of being discharged to the outside, so that the air continuously circulates between the robot cleaner (200) and the robot cleaner station (100). As a result, the heat discharged from the dust collecting motor (145) is not discharged to the kitchen cabinet (2), but is re-introduced into the interior of the robot cleaner (200) and circulated, thereby preventing the interior of the kitchen cabinet (2) from being damaged.

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

At this time, the dust collection motor (145) can be driven together with the suction motor (not shown) of the robot cleaner (200). Since the air exhausted through the air return 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 (145), there is an effect of improving the dust collection efficiency.

Mop washing department

FIG. 17 is an enlarged view illustrating a mop washing unit of a robot cleaner station according to an embodiment of the present invention, FIG. 18 is an enlarged view illustrating a washing water supply unit of a mop washing unit of a robot cleaner station according to an embodiment of the present invention, and FIG. 19 is a drawing illustrating a state in which a dust collection unit and a detergent container are withdrawn from a robot cleaner station according to an embodiment of the present invention.

Referring to FIGS. 17 to 19, the mop washing unit (160) of the robot cleaner station (100) according to an embodiment of the present invention will be described as follows.

The 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).

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).

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

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

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

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

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

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 the 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 supplied to a pair of washing water supply units (161) that are spaced apart from each other through the purified water inlet (161b).

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

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

The detergent container (163) can store liquids including detergent.

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

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

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 parts that are hinge-coupled to the front surface of the detergent container body (163a), and a grip part formed by connecting the pair of connecting parts so that a user can grip it.

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

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).

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

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.

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).

The wastewater tank (164) can provide a space where the washing water used to wash the mop (242) is stored. The washing water discharged from the upper surface of the washing plate (122) can be drained through the passage hole (122b) while descending along the slope of the washing plate (122) after the mop (242) is washed. The washing water that has passed through the passage hole (122b) accumulates in the washing tank (128). In addition, the washing water accumulated in the washing tank (128) can flow into the wastewater suction path (164b) through the wastewater inlet (164c) and can flow into the wastewater tank (164) through the wastewater inlet path (164b). That is, the liquid that has passed through the washing plate (122) can flow along the washing tank (128) and be discharged through the wastewater inlet (164c).

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

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

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) can flow back into the sewage discharge path (164a).

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

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

Mop drying section

FIG. 20 is a perspective view illustrating a mop drying unit of a robot cleaner station according to an embodiment of the present invention, FIG. 21 is an enlarged view illustrating a mop drying unit of a robot cleaner station according to an embodiment of the present invention, and FIG. 22 is a cross-sectional view illustrating a state in which air flows into a heat supply module according to an embodiment of the present invention.

Referring to FIGS. 20 to 22, the robot cleaner station (100) according to one embodiment of the present invention may include a mop drying unit (170). At this time, the mop drying unit (170) may dry the mop (242) of the robot cleaner (200) washed by the mop washing unit (160) or the mop (242) that is wet after the water cleaning task is completed.

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

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

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).

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 communicated with the external space through the external air inlet (171b), and the other side of the external air supply path (171a) can be communicated with the receiving space (S) through the external air discharge portion (171c).

The outside air inlet (171b) may be formed on the rear side of the housing (110). A plurality of outside air inlets (171b) may be formed on the rear side of the housing (110). Air outside the housing (110) may be introduced into the outside air supply path (171a) through the outside air inlet (171b). Accordingly, air outside the housing (110) may be introduced into the interior of the housing (110).

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.

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

In a state where the mop (242) is secured to the washing 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).

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

The heater (171d) is placed 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 discharged through the outside air discharge portion (171c).

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

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

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

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

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

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

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

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

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

Layout

FIGS. 23 and 24 are drawings illustrating the arrangement relationship on a horizontal plane of a robot cleaner station according to an embodiment of the present invention.

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. 23, and FIG. 24 as follows.

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

To this end, the robot cleaner station (100) according to the embodiment of the present invention is characterized by being arranged in a horizontal direction to fit the space formed between the lower plate (23) of the kitchen cabinet (2) and the floor of the kitchen.

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

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).

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

Accordingly, 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).

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.

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.

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 withdrawing the dust bag (not shown) or detergent container (163) with a simple action of pulling the handle can be provided.

Meanwhile, the rear end of the dust collection housing (141) and the detergent container (163) may be arranged at a predetermined distance from the rear end of the housing (110). In addition, a dust collection motor (145) may be arranged between the rear end of the dust collection housing (141) and the rear end of the housing (110). With this configuration, the connection of a wire that supplies power to the dust collection motor (145) may be facilitated. In addition, there is an effect of minimizing the total space occupied by the mounting portion (120), the dust collection housing (141), and the dust collection motor (145) within a limited space.

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 arranged at least between the rear end of the housing (110) and the rear end of the detergent container (163). With this configuration, the path through which washing water flows from the water supply pipe can be made as short as possible. In addition, there is an effect of minimizing the total space occupied by the mounting portion (120), the mop detergent container (163), and the path through which the washing water flows within a limited space.

Meanwhile, the robot cleaner station (100) may have the mop drying unit (170) positioned further rearward than 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).

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) placed on the left and right sides of the mounting unit (120), and a mop drying unit (170) placed on the rear side.

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).

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.

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 where the washing water and the washed waste water 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).

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

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

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

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. With this arrangement, even in a situation where the vertical height is limited, it is possible to charge the robot cleaner (200) using a minimum horizontal space, as well as collect dust from the robot cleaner (200), wash the mop (242), and dry the mop (242).

Drawer

If the charging stand for the robot cleaner is placed under the kitchen cabinet, it can minimize exposure to the outside, thereby providing an interior effect. However, if the robot cleaner breaks down while it is placed under the kitchen cabinet, or if the charging stand for the robot cleaner breaks down, it may be difficult for the user to take it out and repair it. To solve this problem, the present invention may add a drawer (190) to the robot cleaner station (100).

In this regard, FIG. 25 is a drawing for explaining a state in which a drawer is provided in a robot cleaner station according to an embodiment of the present invention, and FIG. 26 is a drawing for explaining a state in which a drawer is withdrawn in a robot cleaner station according to an embodiment of the present invention.

Referring to FIGS. 25 and 26, the drawer (190) of the robot cleaner station (100) according to one embodiment of the present invention will be described as follows.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Additionally, air exhaust pipes connected from the air exhaust port (172b) of the mop drying unit (170) can be connected to each side of the exhaust pipe connection.

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

In addition, the power connection part can be connected to a wire so that an external power source can be connected. At this time, the wire can be connected directly to the power connection part, or the wire can be connected using a wire connection means such as a connector or adapter.

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

Other examples

FIGS. 28 and 29 are plan views illustrating a robot cleaner station according to another embodiment of the present invention, FIG. 30 is an enlarged view illustrating a flow path of a dust collection unit in a robot cleaner station according to another embodiment of the present invention, and FIGS. 31 and 32 are cross-sectional views illustrating a flow path of a dust collection unit in a robot cleaner station according to another embodiment of the present invention.

Referring to FIGS. 28 to 32, a robot cleaner station according to another embodiment of the present invention is described as follows.

To avoid repetitive explanation, except for the configuration not specifically described in this embodiment, the configuration and effect are the same as those of the robot cleaner station according to one embodiment of the present invention, and thus, they can be cited.

In a robot cleaner station according to another embodiment of the present invention, a washing plate (1122) is configured to wash a mop of a robot cleaner (200) and can be installed on the upper side of a washing tank (1128) of a base (1121). In addition, the washing plate (1122) can come into contact with a mop (242) while the robot cleaner (200) is installed.

The washing plate (1122) may be a plate formed so that it slopes downwards toward the center.

Specifically, the cleaning plate (1122) includes a flow guide surface (1122c) formed in a curved shape. In addition, at least one passage hole (1122b) through which a fluid can pass may be formed on the flow guide surface (1122c). In addition, a cleaning protrusion (1122a) may be formed to protrude on the flow guide surface (1122c).

The fluid discharged toward the washing plate (1122) can be guided and flow through the passage hole (1122b).

With this configuration, the wash water and/or air can be guided in flow by the flow guide surface (1122c) and can escape through the passage hole (1122b) into the space formed between the wash plate (1122) and the wash tank (1128). Through this, the heated air can pass through the passage hole (1122b) and be supplied to the wash tank (1128).

Meanwhile, in the present embodiment, at least a portion of the washing plate (1122) may be placed on the upper side of the flow path forming portion (1128c) to be described later. That is, in the present embodiment, the washing plate (1122) may further include a reflux flow path cover portion (1122d) that protrudes upward from the flow guide surface (1122c) and is coupled to the upper side of the flow path forming portion (1128c).

The washing plate (1122) of the present embodiment can be formed in a shape corresponding to the shape of the flow path forming portion (1128c). For example, the front left portion of the washing plate (1122) can be formed to protrude upward from the flow guide surface (1122c) and cover the flow path forming portion (1128c) on the lower side.

With this configuration, the washing plate (1122) and the washing tank (1128) can be accurately combined while providing sufficient space to form a reflux path (1125a).

Meanwhile, the washing tank (1128) is configured to have the washing plate (1122) installed. The washing tank (1128) can be placed on the rear side of the base body (1121a). The washing tank (1128) is placed on the lower side of the washing plate (1122) and is detachably coupled with the washing plate (1122). The washing tank (1128) can be formed to correspond to the washing plate (1122) so that the washing plate (1122) can be inserted. Liquid that has passed through the washing plate (1122) can flow into the washing tank (1128).

The washing tank (1128) may include a washing tank base surface (1128a) through which the fluid passing through the washing plate (1122) flows, and a washing tank wall (1128b) that is formed to protrude vertically from the outer surface of the washing tank base surface. At this time, the washing tank base surface (1128a) may have a height from the ground (the floor of the kitchen) that decreases as it goes toward the rear of the robot cleaner station (100). Through this, the fluid passing through the washing plate (1122) can be collected at the rear of the washing tank (1128) and discharged to the outside through the wastewater inlet (164c).

A flow path forming part (1128c) may be formed in the washing tank (1128) of the present embodiment. The flow path forming part (1128c) may be formed to protrude upward from the washing tank base surface (1128a) to form a reflux flow path (1125a) on the lower side. Specifically, a reflux flow path (1125a) may be formed between the lower surface of the base (1121) and the flow path forming part (1128).

Meanwhile, one side of the interior of the dust collection unit housing (1141) of the present embodiment may be communicated with the first dust collection path (1147), and the other side may be communicated with the second dust collection path (1148). In addition, when a dust bag (not shown) is combined with the dust collection unit housing (1141), the dust bag (not shown) may be communicated with the first dust collection path (1147) inside the dust collection unit housing (1141).

Specifically, the dust collection unit housing (1141) may be formed with an inlet (1141a) communicating with a first dust collection path (1147) and an outlet (1141b) communicating with a second dust collection path (1148).

At this time, the inlet (1141a) may be positioned above the outlet (1141b). As a result, the air and dust introduced through the inlet (1141a) may flow downward, and the dust may be captured in a dust bag (not shown) and then discharged through the outlet (1141b). In this process, since the air flows from the upper side to the lower side, there is an effect of preventing the air from flowing backwards upward or the dust from flying upward.

Meanwhile, in the present embodiment, the discharge port (1141b) may be positioned in front of the inlet port (1141a). For example, the inlet port (1141a) may be formed on the rear surface of the dust collector housing (1141), and the discharge port (1141b) may be formed on the lower surface of the dust collector housing (1141). At this time, the discharge port (1141b) may be positioned closer to the front surface of the dust collector housing (1141) than to the rear surface of the dust collector housing (1141).

In addition, the first dust collection path (1147) and the second dust collection path (1148) may be formed on different surfaces of the dust collection unit housing (1141). For example, the first dust collection path (1147) may be formed on the rear surface of the dust collection unit housing (1141), and the second dust collection path (1148) may be formed along the lower surface of the dust collection unit housing (1141).

Meanwhile, in the present embodiment, the second dust collection path (1148) may be formed in a space formed by combining with the dust bag drawer (1144). That is, a part of the second dust collection path (1148) may be formed in a space formed between the lower surface of the dust collection unit housing (1141) and the dust bag drawer (1144).

Accordingly, a second dust collection path (1148) can pass through the lower side of the inlet (1141a).

Through this, dust and air flowing in through the inlet (1141a) formed at the rear side of the dust collection housing (1141) can flow to the outlet (1141b) formed at the front lower side of the dust collection housing (1141). In this process, dust contained in the air can be sufficiently distributed and stored throughout the dust bag. Accordingly, dust can be prevented from being concentrated and accumulated at a specific location of the dust bag.

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

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