Description

Robot vacuum cleaner station

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

[0002] With the recent advancement of industrial technology, robotic vacuum cleaners are being developed that can autonomously drive and clean areas requiring cleaning without user intervention.

[0003] Such a robot vacuum cleaner is equipped with a sensor capable of recognizing the space to be cleaned, an agitator capable of sweeping the floor surface, and a mop capable of wiping the floor surface, and can drive while sucking up dust from the floor surface of the space recognized by the sensor and wiping with the mop.

[0004] Among robot vacuum cleaners, there are dry robot vacuum cleaners capable of sucking up and removing debris scattered on the floor surface, and wet robot vacuum cleaners capable of wiping the floor surface with a mop containing moisture to effectively remove debris attached to the floor surface. Dry robot vacuum cleaners are equipped with a dust bin and suck up debris from the floor surface using the suction power of a suction motor. Wet robot vacuum cleaners are equipped with a water tank, and water contained in the tank is supplied to the mop so that the mop, while containing moisture, wipes the floor surface to effectively remove debris attached to the floor surface. In addition, there are robot vacuum cleaners equipped with both an agitator and a mop.

[0005] The charging dock of a robot vacuum is a device into which a robot vacuum is docked after cleaning, and which supplies power to the battery equipped in the robot vacuum to charge it. The charging dock is equipped with an internal power supply module. The charging dock is equipped with a charging terminal connected to the power supply module, and the robot vacuum is equipped with a corresponding terminal. When the charging terminal and the corresponding terminal come into contact, power is supplied to the battery to charge it.

[0006] Meanwhile, if a robot vacuum cleaner charging dock is placed indoors, it occupies a certain portion of the space. In this case, indoor space efficiency may suffer. Furthermore, problems may arise where users or pets collide with the robot vacuum cleaner while passing by, resulting in injury to the user or pet as well as damage to the robot vacuum.

[0007] In addition, in the case of stations equipped with a dust collection function, there is a limitation in that the increased volume occupied can detract from the interior design.

[0008] Meanwhile, Chinese Utility Model Registration CN 218922468 U discloses a cleaning station in which a robot vacuum cleaner is combined with the lower side of a washing machine to charge the robot vacuum cleaner, collect dust, and clean the mop of the robot vacuum cleaner.

[0009] However, the above vacuum cleaner station has an open space formed below the washing machine through which a robot vacuum can enter, a detergent and water supply device for washing the mop is provided vertically above the space through which the robot vacuum enters, and a dust bag is placed on the side of the space through which the robot vacuum enters.

[0010] In this type of arrangement, the overall height of the vacuum cleaner station increases, which limits its ability to be mounted using the space underneath furniture, including the sink.

[0011] In addition, since the above vacuum cleaner station must be installed below the washing machine, space for installing the washing machine must be provided, and there is a limitation in that an installation space must be provided with a height exceeding that of the washing machine itself, taking into account the height of the vacuum cleaner station as well.

[0012] Meanwhile, Chinese Utility Model Registration CN 219183596 U discloses a self-cleaning vacuum cleaner station that can freely add cleaning liquid, but does not disclose detailed information regarding hygiene of the dust collection unit.

[0013] In addition, Chinese Utility Model Registration CN 217827730 U discloses drying by acting on the cleaning system of a cleaning robot through a drying device. However, it does not disclose hygiene management for the dust bag.

[0014] However, if unsterilized foreign matter remains in the dust collection unit for a long time, insects and microorganisms may multiply. In particular, mites such as grain mites are microorganisms that parasitize grains that are not sufficiently dried. If grains are collected in the dust collection unit in a hot and humid environment, they can easily multiply and move along the airflow path of the vacuum cleaner station to escape to the outside.

[0015] The present invention was created to improve upon the problems of conventional robot vacuum cleaner stations as described above, and aims to provide a robot vacuum cleaner station that can be built into the lower side of a kitchen cabinet without requiring a separate installation space.

[0016] In addition, the purpose is to provide a robot vacuum cleaner station capable of accommodating a robot vacuum cleaner in the lower space of a kitchen cabinet having a predetermined height limit.

[0017] In addition, the purpose is to provide a robot vacuum cleaner station that can automatically collect dust inside the dustbin of the robot vacuum cleaner when combined with it.

[0018] In addition, the purpose is to provide a robot vacuum cleaner station that can automatically wash the mop of the robot vacuum cleaner when combined with it.

[0019] In addition, the purpose is to provide a robot vacuum cleaner station capable of automatically drying the mop after washing it.

[0020] In addition, the purpose is to provide a robot vacuum cleaner station that can be pulled out for cleaning and repair as needed.

[0021] In addition, the purpose is to provide a robot vacuum cleaner station that can prevent dust from scattering outside when the robot vacuum cleaner is collecting dust.

[0022] In addition, the purpose is to provide a robot vacuum cleaner station that can prevent wastewater from leaking out when washing the robot vacuum cleaner's mop.

[0023] In addition, the purpose is to provide a robot vacuum cleaner station that sterilizes the interior for hygiene of the dust collection housing and dust bag in which dust is collected.

[0024] In addition, the purpose is to provide a robot vacuum cleaner station that sterilizes the dust collection housing and dust bag using a heater, circulation fan, and flow switching valve of the mop drying section without the need for separate additional modules.

[0027] Additionally, the dust collector housing may include a hot air inlet into which air flowing from the dust collector sterilization module is introduced; and a hot air outlet into which air introduced from the hot air inlet is discharged.

[0028] Meanwhile, the dust collection unit sterilization module can be positioned at the rear of the dust collection unit housing.

[0029] It includes a dust collection motor that sucks up dust inside the dust bin of the robot vacuum cleaner; and the dust collection unit sterilization module may be disposed between the dust collection motor and the dust collection unit housing.

[0030] The device includes a mop drying unit disposed within the above housing and drying the mop of the robot vacuum cleaner; the mop drying unit includes a circulation fan that circulates air; and a heater that heats the air circulated by the circulation fan; the dust collection unit housing includes a hot air inlet into which air circulated from the mop drying unit is introduced; and the mop drying unit and the dust collection unit housing can be connected through a first circulation path.

[0031] The above-described mop drying unit may include an outside air supply path that discharges heated air toward the receiving space; and a first path switching valve that selectively opens and closes the outside air supply path and the first circulation path.

[0032] Meanwhile, the robot vacuum cleaner station of the present invention includes a sensor for measuring the moisture content of the mop; and the first flow path switching valve can open the first circulation path when the moisture content measured by the sensor is below a preset reference value.

[0033] Meanwhile, the dust collection housing includes a temperature sensor for measuring temperature inside; and when the temperature measured by the temperature sensor is greater than or equal to a preset reference value, the first flow path switching valve can close the first circulation flow path.

[0034] In addition, the dust collection housing includes a temperature sensor for measuring temperature inside; and if the temperature measured by the temperature sensor is greater than or equal to a preset reference value, the operation of the heater may be terminated.

[0035] Additionally, the dust collector housing may include a hot air discharge port through which air introduced from the hot air inlet is discharged, and an air discharge section including an air discharge path for discharging air inside the housing to the outside, wherein the air discharge section may include a second circulation path for flowing air introduced into the dust collector housing to the air discharge section, and a second path switching valve for opening and closing the second circulation path.

[0036] Meanwhile, the robot vacuum cleaner station of the present invention includes a sensor for measuring the moisture content of the mop; and the second flow path switching valve can open the second circulation flow path when the moisture content measured by the sensor is below a preset reference value.

[0037] In addition, the dust collection housing includes a temperature sensor for measuring temperature inside; and when the temperature measured by the temperature sensor is greater than or equal to a preset reference value, the second flow path switching valve can close the second circulation flow path.

[0038] Meanwhile, the dust collection unit sterilization module includes a light source that emits sterilization light, and the light source may be positioned at the rear upper side inside the dust collection unit housing.

[0039] It includes a dust bag that is housed inside the dust collection unit housing and collects dust introduced from the robot vacuum cleaner; and may include a transparent panel disposed on the upper side of the dust bag and through which the sterilization light is transmitted.

[0040] In addition, the light source may be a UV-C LED.

[0041] Meanwhile, the robot vacuum cleaner station control method of the present invention may include: a mop drying step of drying a mop of a robot vacuum cleaner and measuring the moisture content of the mop through a sensor; a flow path switching step of changing the air flow path by operating a first flow path switching valve when the moisture content measured in the mop drying step is less than a preset reference value; and a dust collection unit sterilization step of sterilizing the interior by discharging hot air into a dust collection unit housing after the flow path switching step.

[0042] Meanwhile, the above dust collection unit sterilization step may operate the first flow path switching valve or stop the operation of the heater when a certain amount of time has elapsed or when the measured value of the temperature sensor is above a reference value.

[0043] As described above, according to the robot vacuum cleaner station of the present invention, a module capable of charging the robot vacuum cleaner, collecting dust, and washing the mop is arranged along a horizontal direction with respect to the robot vacuum cleaner, thereby providing the effect of utilizing the lower space of the kitchen cabinet.

[0044] In addition, the charging port, dust collection unit, mop washing unit, and mop drying unit are arranged around the robot vacuum cleaner, which has the effect of enabling the robot vacuum cleaner to perform various functions simultaneously.

[0046] In addition, since the sides other than the front are concealed by the kitchen cabinets, it has the effect of providing the user with an aesthetic sense in terms of interior design.

[0047] In addition, when combined with a robot vacuum cleaner, it automatically collects dust from the dust bin of the robot vacuum cleaner, so the user only needs to remove the dust bag at regular intervals, which has the effect of reducing the user's effort.

[0048] In addition, when combined with a robot vacuum cleaner, the mop can be automatically washed, effectively reducing the hassle of having to detach and wash the mop separately.

[0049] In addition, since detergent can be added as needed, it has the effect of enhancing the cleaning effect of the mop.

[0050] In addition, since the mop is washed using the kitchen's water supply and drain pipes, it reduces the inconvenience of the user having to separately inject water or drain wastewater.

[0051] In addition, after washing the robot vacuum cleaner's mop, hot air is supplied to the mop to automatically dry it and discharge it, which has the effect of preventing the generation of unpleasant odors.

[0052] In addition, during the process of drying the mop, it discharges the air after drying downstream of the U-trap, which is effective in preventing odors from flowing back.

[0053] In addition, when the robot vacuum cleaner enters the robot vacuum station, the door of the robot vacuum station closes, so it is effective in preventing dust from scattering outside while the dust bin is collecting dust.

[0054] In addition, it is effective in preventing bacterial growth and odor generation by sterilizing the dust collector housing and dust bag.

[0099] Kitchen cabinets and vacuum cleaner system

[0100]

[0101] FIG. 1 illustrates 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 illustrates a relationship in which the piping of the cleaning system according to an embodiment of the present invention is connected to a drain pipe.

[0102] A cleaning system (1) according to an embodiment of the present invention may be provided on the lower side of a kitchen cabinet (2). Specifically, the kitchen cabinet (2) may be placed in a kitchen to store bowls, plates, cups, etc., and may provide a space for cooking food or washing dishes.

[0103] In addition, the kitchen cabinet (2) may be equipped with a countertop (worktop) that can serve as a sink, a countertop, or a work table.

[0104] For example, the kitchen cabinet (2) may include a sink that provides a space for washing dishes on the countertop. Alternatively, the kitchen cabinet (2) may include a countertop for performing cooking tasks. Additionally, the kitchen cabinet (2) may include a gas range stand on which a gas range, induction cooktop, halogen cooktop, oven, etc., are installed on the countertop.

[0105] Generally, a standard cabinet (2) with a width of 600mm in the front-to-back direction and 600mm in the left-to-right direction can be used for the kitchen cabinet.

[0106] A cleaning system (1) according to another embodiment of the present invention may be provided on the lower side of a structure comprising at least one of a water supply pipe and a drain pipe. Specifically, the water supply pipe may refer to a flow path connected to an external water source that supplies fluid to the structure, and the drain pipe may refer to a flow path that discharges fluid discharged from the structure into a sewer.

[0126] robot vacuum cleaner

[0127]

[0128] Meanwhile, FIGS. 6 to 9 disclose drawings for explaining a robot vacuum cleaner in a robot vacuum cleaner system according to an embodiment of the present invention.

[0129] Referring to FIGS. 6 to 9, the structure of the robot vacuum cleaner (200) is described as follows.

[0130] The robot vacuum cleaner (200) can automatically clean the area to be cleaned by driving itself through the area to be cleaned and sucking up foreign substances such as dust from the floor.

[0131] A robot vacuum cleaner (200) according to an embodiment of the present invention is configured to be placed on a floor and move along the floor surface to clean the floor. Accordingly, the following description will define the up and down directions based on the state in which the robot vacuum cleaner (200) is placed on the floor.

[0132] And based on a pair of wheels (260), the side where the auxiliary wheel (270) to be described later is positioned is designated as the front, and the side where the rotating cleaner (240) to be described later is positioned is designated as the rear.

[0133] The 'lowest part' of each component described in the embodiment of the present invention may be the part located lowest in each component when the robot vacuum cleaner (200) according to the embodiment of the present invention is placed on the floor for use, or the part closest to the floor.

[0134] A robot vacuum cleaner (200) according to an embodiment of the present invention comprises a body (210), a dust bin (220), a water tank (230), a rotating cleaning unit (240), an agitator (250), a wheel (260), an auxiliary wheel (270), and a charging terminal (280).

[0135] The body (210) can form the overall shape of the robot vacuum cleaner (200). Each component of the robot vacuum cleaner (200) can be combined with the body (210), and some components of the robot vacuum cleaner (200) can be accommodated inside the body (210).

[0136] Specifically, the body (210) may be equipped with parts of the robot vacuum cleaner (200) in its internal space. For example, the body (210) may accommodate a battery and at least one motor in its internal space.

[0137] In an embodiment of the present invention, the body (210) may be formed in a shape in which the width (or diameter) in the horizontal direction (in the direction parallel to X and Y) is greater than the height in the vertical direction (in the direction parallel to Z). Such a body (210) helps the robot vacuum cleaner (200) form a stable structure and can provide a structure advantageous for avoiding obstacles while the robot vacuum cleaner (200) moves (drives).

[0138] When viewed from above or below, the body (210) can be made in various shapes, such as circular, elliptical, or square.

[0139] The body (210) can be configured by dividing it into a lower body and an upper body, and the lower body and the upper body can be combined to form a space inside.

[0140] The lower body can be combined with the upper body to form a space capable of accommodating a battery, at least one sensor, and at least one motor inside.

[0141] In the lower body, an intake part (211) into which air is introduced and a hole for accommodating a pair of wheels (260) may be formed.

[0142] The suction part (211) may be a passage through which dust from the bottom surface is introduced. Additionally, the suction part (211) may be in communication with a suction passage (not shown) formed inside the body (210), and the suction passage may be in communication with the internal space of the dust container (220).

[0143] Meanwhile, the lower body may be further provided with an exhaust passage. One side of the exhaust passage may be in communication with the internal space of the dust bin (220), and the other side may be in communication with the exhaust port. At this time, a filter may be placed in the exhaust port.

[0144] With this configuration, air introduced through the intake section (211) flows into the dust bin (220) through the intake path and can be discharged to the exhaust port through the exhaust path.

[0145] An agitator (250), to be described later, can be rotatably accommodated in the suction part (211). With this configuration, dust around the suction part (211) can be guided into the suction part (211) by the rotation of the agitator (250), and the efficiency of dust suction can be increased.

[0146] The upper body can form the upper exterior of the robot vacuum cleaner (200). Although not illustrated, the upper body may be equipped with a display.

[0147] The robot vacuum cleaner (200) of the present invention may include a bumper. The bumper is formed to be attached along the edge of the body (210) and to move relative to the body (210).

[0148] The bumper may be attached along a portion of the edge of the body (210) or along the entire edge of the body (210). At least one elastic member (not shown) may be provided between the bumper and the body (210). With this configuration, when the bumper comes into contact with an obstacle or the like and moves relative to the center of the body (210), the bumper can return to its original position by the restoring force of the elastic member (not shown), and can absorb or disperse the impact applied to the bumper, thereby preventing and reducing the transmission of impact to the body (210).

[0149]

[0150] The dustbin (220) may be equipped to suck in external dust and air and store dust.

[0151] The dust container (220) can store dust that enters through the suction path. The dust container (220) may have a dust inlet that communicates with the suction path, an internal space for storing dust, and an air outlet for discharging air.

[0152] The dustbin (220) may be provided inside the body (210). At this time, the dustbin (220) may be fixedly connected to the body (210) or, depending on the embodiment, may be provided so as to be detachable.

[0153] Meanwhile, in the present invention, a dust discharge channel may be formed in the dust bin (220). The dust discharge channel may connect the internal space of the dust bin (220) with the external space of the robot vacuum cleaner (200). With such a configuration, when dust is collected through the robot vacuum cleaner station (100), the dust inside the dust bin (220) can be removed.

[0154] Meanwhile, a dust outlet (221) communicating with the dust discharge path may be formed in the dust container (220) according to an embodiment of the present invention. For example, the dust outlet (221) may be formed on one side of the rear of the outer surface (or outer circumference) of the body (210). For another example, the dust outlet (221) may be formed on the outer surface of the dust container (220).

[0155] Additionally, the robot vacuum cleaner (200) according to an embodiment of the present invention may be provided with a dust bin door (222) capable of selectively opening and closing the dust discharge port (221). Specifically, the dust bin door (222) may be coupled to the body (210) and positioned to block the dust discharge port (221). For example, the dust bin door (222) may be formed of a rubber or resin material and configured to be flip-floppy, with one side fixedly coupled to the body (210).

[0156] With this configuration, when the dust collection motor (145) of the robot vacuum cleaner station (100) described later is operated, the dust bin door (222) is elastically deformed by the driving force of the dust collection motor (145), and the dust discharge port (221) is opened so that dust inside the dust bin (220) can be collected into the dust collection unit (140) of the robot vacuum cleaner station (100).

[0157]

[0158] The water container (230) is formed in the shape of a container having an internal space for storing a liquid such as water. The water container (230) is placed inside the body (210), and may be fixedly connected to the body (210) or detachably connected to the body (210).

[0159] The water tank (230) includes a supply unit (231) and a nozzle (not shown). The supply unit (231) may be provided to supply a liquid, such as water, from the outside. For example, the supply unit (231) may have an inlet formed on the rear side of the outer surface (or outer circumference) of the body (210) and may be connected to a storage space inside the water tank (230) through a water supply hose.

[0160] At this time, the supply unit (231) may be positioned on the opposite side of the left and right direction of the robot vacuum cleaner (200) in relation to the dust outlet (221). For example, if the dust outlet (221) is positioned on the rear left side of the body (210), the supply unit (231) may be positioned on the rear right side of the body (210).

[0161] Through this configuration, the robot vacuum cleaner (200) is coupled to the robot vacuum cleaner station (100), and the robot vacuum cleaner station (100) can simultaneously perform dust collection and water injection.

[0162] Meanwhile, the nozzle (not shown) is formed in the shape of a tube or pipe and is connected to the water tank (230) so that the liquid inside the water tank (230) can flow through it. One end of the nozzle (not shown) is connected to the water tank (230), and the other end is positioned so as to be located on the upper side or on the rotating plate of a pair of rotating plates (241), respectively, thereby allowing the liquid inside the water tank (230) to be supplied to a pair of rags (242) respectively.

[0163] That is, the nozzle (not shown) may be formed in a shape where one tube is branched into two, and in this case, one of the branched ends may be located on the upper side of the left mop, and the other branched end may be located on the upper side of the right mop.

[0164] Meanwhile, although not shown, the water tank (230) is equipped with a pump to allow water inside the water tank (230) to flow through a nozzle (not shown). Therefore, when the pump of the water tank (230) is operated, the liquid stored inside the water tank (230) can be discharged to a rotating cleaner (240) through a nozzle (not shown).

[0165]

[0166] The rotating cleaning unit (240) includes a rotating plate (241) and a mop (242).

[0167] The rotating plate (241) may be provided as a pair including a left rotating plate and a right rotating plate, and the mop (242) may be provided as a pair including a left mop and a right mop.

[0168] The rotating plate (241) can be rotatably positioned on the bottom surface of the body (210), and the mop (242) can be attached to the lower side.

[0169] The rotating plate (241) is formed to have a predetermined area and is formed in the shape of a flat plate or a flat frame. This rotating plate (241) is generally laid horizontally, and accordingly, is formed in a shape where the width (or diameter) in the horizontal direction is sufficiently larger than the height in the vertical direction. The rotating plate (241) attached to the body (210) may be parallel to the bottom surface (B) or may be inclined with respect to the bottom surface (B). The rotating plate (241) may be formed in the shape of a circular plate, the bottom surface of the rotating plate (241) may generally be circular, and the rotating plate (241) may be formed in a rotationally symmetrical shape overall.

[0170] A pair of rotating plates (241) can be symmetrical to each other.

[0171] The mop (242) can be attached to the lower side of the rotating plate (241) so as to face the bottom surface (B).

[0172] The mop (242) is formed such that the bottom surface facing the floor has a predetermined area, and the mop (242) is formed in a flat shape. The mop (242) is formed such that the width (or diameter) in the horizontal direction is sufficiently larger than the height in the vertical direction. When the mop (242) is attached to the body (210), the bottom surface of the mop (242) may be parallel to the bottom surface (B) or may be inclined with respect to the bottom surface (B).

[0173] The bottom surface of the mop (242) can generally be circular, and the mop (242) can be formed in a rotationally symmetrical shape overall. Additionally, the mop (242) can be attached to the bottom surface of the rotating plate (241) and can be coupled to the rotating plate (241) to rotate together with the rotating plate (241).

[0174] Meanwhile, although not shown, the rotating cleaning unit (240) may be equipped with a driving unit that applies rotational force to the rotating plate (241). For example, the driving unit may be equipped with a motor and at least one gear. Thus, when the driving unit is operated, the rotating plate (241) and the mop (242) rotate to wipe and clean the floor surface.

[0175]

[0176] The agitator (250) is rotatably equipped with a plurality of brushes to guide external dust and air into the dust bin (220). At this time, the agitator (250) may be equipped with at least one gear.

[0177] Meanwhile, the agitator (250) according to the present embodiment may receive rotational power by having a separate agitator motor (not shown) installed, and may also receive rotational power from a driving motor according to the embodiment, and may also receive rotational power from the driving unit of the rotating cleaning unit (240).

[0178]

[0179] 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).

[0180] The wheel (260) is provided on the body (210) and can roll on the bottom surface.

[0181] The wheel (260) may be composed of a first driving wheel and a second driving wheel. In this case, the first driving wheel may be formed identically to the second driving wheel, or may be formed symmetrically. For example, if the first driving wheel is located on the left side of the robot vacuum cleaner (200), the second driving wheel may be located on the right side of the robot vacuum cleaner (200), and in this case, the first driving wheel and the second driving wheel may be symmetrical to each other.

[0182] The drive unit (not shown) may be comprised of a driving motor and a gear. In this case, the driving motor is housed inside the body (210) and can provide power to the wheel (260). The driving motor may include a first driving motor and a second driving motor.

[0183] The driving motor may be an electric motor. Multiple gears are configured to mesh and rotate with each other, connecting the driving motor and the wheel (260) and transmitting the rotational power of the driving motor to the wheel (260). Therefore, the wheel (260) can rotate when the rotation axis of the driving motor rotates.

[0184] 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.

[0185] The auxiliary wheel (270) is provided on the lower side of the body (210) and can roll on the floor surface (surface to be cleaned). The auxiliary wheel (270) can support the body (210) on the floor surface together with a pair of wheels (260). With this configuration, the auxiliary wheel (270) can guide the movement of the robot vacuum cleaner (200) while minimizing friction between the robot vacuum cleaner (200) and the floor surface.

[0186] A suction motor (not shown) can generate a suction force capable of sucking in external dust and air through the suction section (211). For example, the suction motor (not shown) may be an electric motor. External dust and air can be drawn into the suction section (211) by the suction force generated by the suction motor (not shown), and after passing through the suction path, can reach the dust bin (220).

[0187] Although not illustrated, the battery is configured to be coupled to the body (210) and to supply power to other components forming the robot vacuum cleaner (200). The battery can supply power to at least one motor equipped in the robot vacuum cleaner (200). For example, the battery can supply power to the motors equipped in the rotary cleaner (240), the agitator (250), the wheel (260), and the suction motor (not illustrated).

[0188] In addition, the battery can supply power to the sensor unit (not shown) and the control unit (not shown).

[0189] The battery can be charged by an external power source, and for this purpose, a charging terminal (280) for charging may be provided on one side of the body (210). For example, the charging terminal (280) may be positioned on the rear side of the outer surface of the body (210). When the robot vacuum cleaner (200) is connected to the robot vacuum cleaner station (100), the charging terminal (280) can come into contact with the power supply terminal (123b) of the robot vacuum cleaner station (100) to receive power.

[0191] Robot vacuum cleaner station

[0192]

[0193] FIG. 10 shows a perspective view for explaining a robot vacuum cleaner station according to an embodiment of the present invention, and FIG. 11 shows a plan view of FIG. 10.

[0194] Referring to FIGS. 10 and FIGS. 11, the robot vacuum cleaner station (100) of the present invention is described as follows.

[0195] A robot vacuum cleaner (200) can be accommodated in the robot vacuum cleaner station (100). A robot vacuum cleaner (200) can be attached to the mounting portion (120) of the robot vacuum cleaner station (100).

[0196] The robot vacuum cleaner station (100) may include a housing (110).

[0197] The housing (110) can form the exterior of the robot vacuum cleaner station (100). For example, the housing (110) can be formed in a shape similar to a cuboid including at least one outer wall surface.

[0198] The housing (110) may have a space formed therein to accommodate a seating portion (120), a dust collection channel (not shown), a dust collection portion (140), a dust collection motor (145), a mop washing portion (160), a mop drying portion (170), and a circulation channel.

[0199] The housing (110) can be mounted on the lower side of the kitchen cabinet (2). Specifically, the housing (110) can be installed in a mounting space formed between the lower plate (23) of the kitchen cabinet (2) and the floor of the kitchen.

[0200] The housing (110) includes a pair of outer walls (111) facing each other. The outer walls (111) may refer to surfaces formed along the direction of gravity.

[0201] For example, a pair of outer walls (111) may be installed on the lower side of the kitchen cabinet (2) at a predetermined distance apart. For another example, the housing (110) may further include a bottom surface facing the kitchen floor, and the pair of outer wall surfaces may be connected through the bottom surface. For yet another example, the housing (110) may further include a bottom surface facing the kitchen floor and an upper surface (113) facing the lower plate (23) of the kitchen cabinet (2), 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). Thus, even if foreign matter falls downward from the kitchen cabinet (2), it is possible to prevent the components of the robot vacuum cleaner (200) and the robot vacuum cleaner station (100) from being contaminated. As another example, the housing (110) may further include the bottom surface, the upper surface (112), and the rear surface (111b) facing the wall of the building.

[0202] With this configuration, components of a robot vacuum cleaner station (100) can be accommodated inside the housing (110) (between a pair of outer walls).

[0203] Additionally, a robot vacuum cleaner (200) can be accommodated inside the housing (110). The housing (110) may be arranged such that a pair of outer walls (111) are spaced apart from the maximum horizontal width of the robot vacuum cleaner (200). With this configuration, the robot vacuum cleaner (200) can enter and exit the housing (110).

[0204] At this time, in this embodiment, the robot vacuum cleaner (200) can enter and exit the front of the robot vacuum cleaner station (100). Here, "front" may refer to the direction in which the door (126) is provided relative to the interior of the robot vacuum cleaner station (100).

[0205] Additionally, the rear may refer to the opposite direction from the front relative to the interior of the robot vacuum cleaner station (100). For example, a wall of a building (not shown) may be placed at the rear of the robot vacuum cleaner station (100).

[0206] In addition, when looking forward from inside the robot vacuum cleaner station (100), the left side can be called the left side and the right side the right side.

[0207] That is, the outer wall (111) of the robot vacuum cleaner station (100) can be positioned on the left side and the right side, respectively.

[0208] Accordingly, the upper side of the housing (110) is covered by the kitchen cabinet (2), and the lower side of the housing (110) can be covered by the kitchen floor. Additionally, the left and right sides of the housing (110) are covered by the outer wall but are positioned at the bottom of the kitchen cabinet (2). At this time, since the lower part of the kitchen cabinet (2), excluding the robot vacuum cleaner station (100), is finished by a baseboard, as a result, only the front of the housing (110) can be exposed to the outside.

[0209] Through this, the robot vacuum cleaner station (100) and the robot vacuum cleaner (200) can be minimized from being exposed to the outside.

[0210] With such a configuration, the robot vacuum cleaner station (100) of the present invention has the effect of providing an aesthetic sense to the user in terms of interior design.

[0211] Meanwhile, although not shown, the housing (110) may have a space through which a water supply hose connected to a water supply pipe passes, a space through which a drainage hose through which wastewater generated after washing the mop (242) is discharged, and a space through which a hose through which moisture generated during the drying process of the mop (242) is discharged. For example, a space through which the above hoses can pass may be formed in at least one of the outer wall (111) and the upper side (112) of the housing (110).

[0212]

[0213] joint

[0214]

[0215] As illustrated in FIG. 11, the robot vacuum cleaner station (100) may include a seating portion (120).

[0216] The robot vacuum cleaner (200) and the robot vacuum cleaner station (100) can be physically, electrically, and / or electrically connected through the mounting portion (120).

[0217] The seating portion (120) can be placed inside the housing (110).

[0218] At this time, according to the embodiment, the seating portion (120) may be provided so as to be pulled out from the housing (110) through the drawer (190).

[0219] With this configuration, if the mounting part (120) needs to be cleaned or repaired, or if some parts need to be replaced, the user can easily pull out the mounting part (120) for maintenance.

[0220] An entrance (127) into which a robot vacuum cleaner (200) is inserted may be formed in the seating portion (120). The entrance (127) may refer to a space formed on the front surface of the robot vacuum cleaner station (100).

[0221] The entrance (127) can be formed to a size that allows the robot vacuum cleaner (200) to pass through. That is, the height of the entrance (127) is formed to be greater than the height of the robot vacuum cleaner (200). At this time, the entrance (127) may refer to a space formed upward along a vertical direction from the front end of the base (121) to be described later, and the top of the entrance may be the same as the lower surface of the lower plate (23) of the kitchen cabinet (2) or the top of the housing (110).

[0222] Additionally, the entrance (127) is formed such that its width in the left-right direction is greater than the maximum width of the robot vacuum cleaner (200). At this time, at least one of a dust collection unit (140) and a mop washing unit (160) may be arranged on the left and right sides of the entrance (127). Accordingly, the left and right ends of the entrance (127) may form a boundary with the dust collection unit (140) and the mop washing unit (160). If either the dust collection unit (140) or the mop washing unit (160) is absent, it is also possible for the outer wall surface of the housing (110) to form the boundary.

[0223] At this time, the entrance (127) can be opened and closed by a door (126). The door (126) is positioned 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 seating portion (120).

[0224] The door (126) can be rotated by a door drive unit (126a). For example, the door drive unit (126a) may be a motor.

[0225] For example, the door (126) may be formed in the shape of a rectangular flat plate, and a hinge portion (126b) may be provided at the top, and a door driving portion (126a) may be connected to one end of the hinge portion (126b) in the axial direction. At this time, the hinge portion (126b) of the door (126) may be directly connected to the shaft of the door driving portion (126a), or may be connected so as to transmit power through at least one gear.

[0226] The door (126) can maintain the doorway (127) closed when the robot vacuum cleaner (200) is accommodated in the seating area (120). Then, when the robot vacuum cleaner (200) starts moving from the seating area (120), the doorway (126) can be rotated to open the doorway (127). Then, the door (126) can be rotated to close the doorway (127) after the robot vacuum cleaner (200) passes through the doorway (127). Additionally, the door (126) can be rotated to open the doorway (127) when the robot vacuum cleaner (200) approaches from outside the vacuum cleaner station (100).

[0227]

[0228] The seating portion (120) may include a receiving space (S), a base (121), a connecting wall (123), and an inner wall (124).

[0229] A robot vacuum cleaner (200) can be accommodated in the receiving space (S) of the seating portion (120). For example, the receiving space (S) may refer to a space enclosed by a base (121), a connecting wall (123), and an inner wall (124). For another example, the receiving space (S) may refer to a space enclosed by a base (121), a cleaning plate (122), a connecting wall (123), and an inner wall (124). For yet another example, the receiving space (S) may refer to a space where the robot vacuum cleaner (200) is located while connected to a power supply terminal (123b), or a space where the robot vacuum cleaner (200) is located while the dust bin (220) of the robot vacuum cleaner (200) is connected to a dust passage hole (123a).

[0230] The base (121) can be positioned so that the robot vacuum cleaner station (100) contacts the floor surface, and is configured to support the robot vacuum cleaner (200) when the robot vacuum cleaner (200) is coupled to the robot vacuum cleaner station (100). The 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).

[0231] The base body (121a) can form the overall shape of the base (121). An inclined section (121b), a wheel coupling section (121c), an agitator receiving section (121d), and a washing tank (128) may be arranged on the base body (121a).

[0232] The base body (121a) may be formed such that the width (or diameter) in the horizontal direction (parallel to X and Y) is greater than the height in the vertical direction (parallel to Z). Due to this structure, the robot vacuum cleaner station (100) can be stably supported on the floor surface.

[0233] A circulation path may be provided inside the base body (121a). Accordingly, air discharged from the dust collection motor (145) can flow through the circulation path formed inside the base body (121a) and be exhausted to the air return port (125b).

[0234] The inclined section (121b) can be placed at the entrance where the robot vacuum cleaner (200) climbs from the base body (121a).

[0235] The inclined section (121b) may have an upward slope toward the front of the direction in which the robot vacuum cleaner (200) enters. More specifically, the inclined section (121b) may be connected such that the front end of the entrance side is not at a height difference from the ground, but may have an upward slope toward the front of the direction in which the robot vacuum cleaner (200) enters. At this time, the front of the direction in which the robot vacuum cleaner (200) enters refers to the rear when viewed from the robot vacuum cleaner station (100). Thus, the robot vacuum cleaner (200) can easily step up from the ground to the robot vacuum cleaner station (100).

[0236] A wheel guide section (121ba) may be provided in the inclined section (121b).

[0237] The wheel guide section (121ba) may be formed in the shape of a groove to guide the movement of the wheel (260) of the robot vacuum cleaner (200). The surface of the wheel guide section (121ba) may be formed to correspond to the surface of the wheel (260) so that the robot vacuum cleaner (200) can drive stably. Additionally, the wheel guide section (121ba) may be formed such that the width of the groove is greater than the width of the wheel (260) at the entrance where the robot vacuum cleaner (200) climbs, and the width of the groove becomes narrower relative to the entrance as it moves forward along the climbing path of the robot vacuum cleaner (200). Thus, the wheel (260) of the robot vacuum cleaner (200) can easily enter the robot vacuum cleaner station (100), but left and right movement is restricted by the groove that gradually narrows, allowing the wheel (260) to be guided to the correct position.

[0238] An auxiliary wheel guide (121bb) may be provided in the inclined section (121b).

[0239] The auxiliary wheel guide portion (121bb) may be formed in a groove shape to guide the movement of the auxiliary wheel (270) of the robot vacuum cleaner (200). Additionally, the auxiliary wheel guide portion (121bb) may be formed in a protruding shape so as to come into contact with the auxiliary wheel (270) when the wheel (260) of the robot vacuum cleaner (200) is seated on the wheel guide portion (121ba). Thus, when the robot vacuum cleaner (200) travels along the inclined portion (121b), it can travel while being stably supported by the auxiliary wheel (270) as well as the wheel (260).

[0240] The wheel (260) of the robot vacuum cleaner (200), which has moved upward along the wheel guide (121ba), can be placed on the wheel coupling portion (121c). When the wheel (260) of the robot vacuum cleaner (200) is placed on the wheel coupling portion (121c), a physical connection between the robot vacuum cleaner (200) and the robot vacuum cleaner station (100) can be achieved. To allow the robot vacuum cleaner (200) to stop stably, the surface of the wheel coupling portion (121c) can be formed to correspond to the surface of the wheel (260). The wheel coupling portion (121c) can be extended from the upper end of the wheel guide (121ba). The wheel coupling portion (121c) can be connected to the wheel guide (121ba) without a step. Thus, the robot vacuum cleaner (200) can easily move past the inclined portion (121b) to the wheel coupling portion (121c).

[0241] The wheel coupling portion (121c) may be positioned at the stopping position of the left and right wheels (260) of the robot vacuum cleaner (200) so that the robot vacuum cleaner (200) stops at the correct position. Here, the stopping position of the wheel (260) means a position determined for the robot vacuum cleaner (200) to stop in order to be connected to the power supply terminal (123b) and / or a position determined for the dust bin (220) of the robot vacuum cleaner (200) to stop in order to be connected to the dust passage hole (123a).

[0242] The shape of the wheel coupling part (121c) can be formed in an arch shape, that is, a shape corresponding to the shape of the wheel (260) of the robot vacuum cleaner (200). Through this configuration, the robot vacuum cleaner (200) can move along the wheel guide part (121ba) and stop as soon as the wheel (260) is inserted into the wheel coupling part (121c), and the wheel (260) can be stably seated on the arch-shaped wheel coupling part (121c).

[0243] At least a portion of the agitator (250) of the robot vacuum cleaner (200) can be accommodated in the agitator receiving portion (121d). Specifically, the agitator receiving portion (121d) can provide a space in which the lower portion of the agitator (250) of the robot vacuum cleaner (200) is accommodated while the wheel (260) of the robot vacuum cleaner (200) is seated in the wheel coupling portion (121c).

[0244] The agitator receiving portion (121d) may be formed between the wheel coupling portions (121c). The agitator receiving portion (121d) may be formed in a shape corresponding to the agitator (250) of the robot vacuum cleaner (200). The agitator receiving portion (121d) may be formed in a rectangular shape with an open top. The lower surface of the agitator receiving portion (121d) may be sealed by the bottom surface of the base body (121a) or the bottom surface of the housing (110). Accordingly, the agitator (250) of the robot vacuum cleaner (200), which has moved upward along the inclined portion (121b), may be seated in the 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).

[0245] The agitator receiving portion (121d) may include a recess (121da) and a protrusion (121db).

[0246] The recess (121da) can be formed to be recessed from the base (121). The recess (121da) can form a receiving space in which at least a portion of the agitator (250) is received. In this way, at least a portion of the agitator (250) can be received in the receiving space of the recess (121da) while the wheel (260) of the robot vacuum cleaner (200) is seated on the wheel coupling portion (121c).

[0247] The receiving space of the recess (121da) can be connected to the receiving space (S) of the seating portion (120).

[0248] The protrusion (121db) may be formed to protrude from the base (121). The protrusion (121db) may be positioned along the edge of the recess (121da). Additionally, when the agitator (250) is received in the receiving space of the recess (121da), the protrusion (121db) may be positioned at a predetermined distance from the body (210) of the robot vacuum cleaner (200).

[0249] The protrusion (121db) can guide air discharged through the air circulation port (125b) to the suction port (211) of the robot vacuum cleaner (200). In this way, air discharged into the receiving space of the recess (121da) can be guided to the suction port (211) of the robot vacuum cleaner (200) by the protrusion (121db).

[0250] An air return port (125b) may be formed in the agitator receiving portion (121d). The air return port (125b) may be formed on the side of the agitator receiving portion (121d). The air return port (125b) may connect the recess (121da) and the dust collection motor (145) through a circulation path. The recess (121da) and the circulation path may be connected through the air return port (125b). Thus, air discharged from the dust collection motor (145) may pass through the air return port (125b) and be discharged to the recess (121da) of the agitator receiving portion (121d).

[0251]

[0252] The connecting wall (123) is configured to accommodate the dust passage hole (123a), power supply terminal (123b), and water supply nozzle (123c) of the robot vacuum cleaner station (100). The connecting wall (123) can spatially separate the receiving space (S) from the parts of the robot vacuum cleaner station (100). The connecting wall (123) can extend along the vertical direction from the rear side of the base (121). The connecting wall (123) can be formed in correspondence with the shape of the robot vacuum cleaner (200). For example, if the body (210) of the robot vacuum cleaner (200) is cylindrical, the connecting wall (123) can be formed in an arc shape having a predetermined radius. With such a configuration, the outer perimeter of the robot vacuum cleaner (200) can be surrounded, and the surface area facing the outer surface of the robot vacuum cleaner (200) can be increased. Additionally, the robot vacuum cleaner (200) can be stably supported.

[0253]

[0254] A dust passage hole (123a) may be formed in the seating portion (120) to allow air from outside the housing (110) to flow into the interior. Specifically, a dust passage hole (123a) may be formed in the connecting wall (123) to allow air from outside the housing (110) to flow into the interior. The dust passage hole (123a) may be in communication with the dust bin (220) of the robot vacuum cleaner (200). The dust passage hole (123a) may be in communication with the dust outlet (221) of the dust bin (220) of the robot vacuum cleaner (200). The dust passage hole (123a) may be formed in a hole shape corresponding to the shape of the dust bin (220) so that dust from the dust bin (220) flows into the dust collection portion (140). The dust passage hole (123a) may be formed corresponding to the shape of the dust outlet (221) of the dust bin (220). The dust passage hole (123a) may be formed to communicate with a dust collection channel (not shown). Air sucked into the dust passage hole (123a) may be exhausted through the air return section (125) after flowing through the dust collection channel (not shown).

[0255]

[0256] The robot vacuum cleaner station (100) may include a power supply module that supplies power to the robot vacuum cleaner (200). The power supply module includes a power supply module housing and a power supply terminal (123b), and a circuit board and components for power supply may be mounted within the power supply module housing. The power supply terminal (123b) may be positioned forward from the power supply module housing and exposed on the coupling wall (123).

[0257] The power supply terminal (123b) can supply power to a robot vacuum cleaner (200) coupled to the mounting portion (120). The power supply terminal (123b) can be electrically connected by contacting the charging terminal of the robot vacuum cleaner (200). The power supply terminal (123b) can be placed on the mounting portion (120). Specifically, the power supply terminal (123b) can be placed on the coupling wall (123). The power supply terminal (123b) can be electrically connected to the robot vacuum cleaner (200) coupled to the coupling wall (123). The power supply terminal (123b) can supply power to the battery of the robot vacuum cleaner (200) coupled to the coupling wall (123).

[0258]

[0259] The robot vacuum cleaner station (100) may further include a water supply nozzle (123c).

[0260] The water supply nozzle (123c) can be connected to the supply section (231) of the water tank (230) of the robot vacuum cleaner (200). Specifically, the water supply nozzle (123c) can be connected to the inlet of the water tank (230). The inlet is configured to be connected to the water tank (230) of the robot vacuum 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 vacuum cleaner (200).

[0261]

[0262] The inner wall (124) is configured to spatially separate the receiving space (S) of the seating portion (120) from the parts of the robot vacuum cleaner station (100). A pair of inner walls (124) may be arranged on the left and right sides of the base (121). The inner walls (124) may be connected to both ends of the connecting wall (123). The inner walls (124) may extend from the left and right sides of the base (121) in a direction intersecting the base (121). Specifically, the inner walls (124) may extend vertically from the left and right sides of the base (121). 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).

[0263] Meanwhile, various components such as a dust collection channel (not shown), a dust collection unit (140), a dust collection motor (145), a detergent container (163), and a wastewater container (164) may be arranged on the outer side of the inner wall (124). Specifically, the dust collection unit (140), the detergent container (163), and the wastewater container (164) may be accommodated in the space between the inner wall (124) and the outer wall (111) of the housing (110).

[0264] The dust collector (140) and the detergent container (163) can be separated by sliding from the space between the inner wall (124) and the outer wall (111) of the housing (110). The left-right width of the dust collector (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).

[0265]

[0266] The cleaning plate (122) is configured to clean the mop of the robot vacuum cleaner (200), and the cleaning plate (122) can be placed in the cleaning tank (128) of the base (121). Additionally, the cleaning plate (122) can come into contact with the mop (242) while the robot vacuum cleaner (200) is placed thereon.

[0267] The cleaning plate (122) may be a plate formed to slope downward as it faces the center overall.

[0268] Specifically, the cleaning plate (122) includes a flow guide surface (122c) formed in a curved shape. In addition, at least one passage hole (122b) through which fluid can pass may be formed in the flow guide surface (122c). Furthermore, a cleaning projection (122a) may be formed protrudingly on the flow guide surface (122c).

[0269] At this time, a pair of cleaning protrusions (122a) may be symmetrically formed on the fluid guide surface (122c). Specifically, a pair of cleaning protrusions (122a) may be positioned vertically below a pair of mops (242) of a robot vacuum cleaner (200), positioned to face the pair of mops (242), and positioned to be able to contact at least a part of the pair of mops (242).

[0270] Additionally, multiple through holes (122b) may be formed on the flow guide surface (122c), and may be formed between a pair of washing protrusions (122a). For example, multiple through holes (122b) may be formed on the flow guide surface (122c), including the lowest position from the ground (kitchen floor), and may be formed between a pair of washing protrusions (122a). Through this, fluid discharged between a pair of washing protrusions (122a) can be guided into the through holes (122b) and flow.

[0271] Meanwhile, the height of the flow guide surface (122c) from the kitchen floor can increase as it moves further back from the location where the through hole (122b) is formed. That is, the height of the flow guide surface (122c) from the kitchen floor can increase as it approaches the external air discharge section (171c) to be described later.

[0272] With this configuration, the washing water and / or air is guided by the flow guide surface (122c) and can exit through the passage hole (122b) into the space formed between the washing plate (122) and the washing tank (128). Through this, heated air can pass through the passage hole (122b) and be supplied to the washing tank (128).

[0273] Accordingly, when the drive unit of the rotating cleaning unit (240) is driven while the mop (242) of the robot vacuum cleaner (200) is seated on the cleaning plate (122), the mop (242) rotates. At this time, when the mop (242) rotates while cleaning water is supplied to the cleaning plate, the mop (242) can be cleaned by friction with the stationary cleaning protrusion (122a).

[0274]

[0275] The washing tank (128) is configured to accommodate the washing plate (122). The washing tank (128) may be positioned at the rear side of the base body (121a). The washing tank (128) is positioned at the lower side of the washing plate (122) and is detachably coupled to the washing plate (122). The washing tank (128) may be formed to correspond to the washing plate (122) so that the washing plate (122) can be fitted into it. Liquid that has passed through the washing plate (122) may flow into the washing tank (128).

[0276] The washing tank (128) may include a washing tank base surface through which fluid passing through the washing plate (122) flows, and a washing tank wall formed to protrude vertically from the outer edge 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 moves toward the rear of the robot vacuum cleaner station (100). Through this, fluid passing through the washing plate (122) can be collected at the rear of the washing tank (128) and discharged to the outside through the wastewater inlet (164c) to be described later.

[0278] dust collector

[0279]

[0280] FIGS. 12 and 13 show side views illustrating a dust collection unit of a robot vacuum cleaner station according to an embodiment of the present invention, and FIG. 14 shows a cross-sectional view illustrating a dust collection path of a robot vacuum cleaner station according to an embodiment of the present invention.

[0281] Referring to FIGS. 12 to 14 and FIG. 17, the dust collection unit (140) is described as follows.

[0282] The dust collection unit (140) can collect dust from the dust bin (220) of the robot vacuum cleaner (200). The dust collection unit (140) can be placed inside the housing (110). The dust collection unit (140) can be placed outside the seating unit (120). At this time, the receiving space (S) can be placed inside the seating unit (120).

[0283]

[0284] 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).

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

[0286]

[0287] The dust collection housing (141) is coupled to the inside so that a dust bag drawer (144) can be pulled out, and a dust bag (not shown) can be stored inside the dust bag drawer (144). For example, the dust collection housing (141) is formed in the shape of a rectangular tube with an open front, and the rear internal space can be connected to the first dust collection path (147) and the second dust collection path (148).

[0288] One side of the interior of the dust collection housing (141) may be in communication with the first dust collection path (147), and the other side may be in communication with the second dust collection path (148). Additionally, when a dust bag (not shown) is attached to the dust collection housing (141), the dust bag (not shown) may be in communication with the first dust collection path (147) inside the dust collection housing (141).

[0289] A dust bag (not shown) may refer to a dust bag that collects dust sucked in from inside the dust bin (220) of the robot vacuum cleaner (200) by a dust collection motor (145). The dust bag (not shown) may be detachably connected to a dust collection housing (141). Thus, the dust bag (not shown) may be separated from the dust collection housing (141) and discarded, and a new dust bag (not shown) may be connected to the dust collection housing (141). That is, the dust bag (not shown) may be defined as a consumable part.

[0290] A dust bag (not shown) can be provided so that when suction force is generated by a dust collection motor (145), its volume increases and dust is contained inside.

[0291] 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 fabric material and may have a cuboid shape corresponding to the shape of the dust collection housing (141) when the volume is increased.

[0292] A filter (142) may be placed between the dust collection housing (141) and the second dust collection path (148). The filter (142) may be placed at the air outlet (141b). The filter (142) may be a pre-filter or a HEPA filter. Air passing through a dust bag (not shown) may pass through the filter (142) and flow into the second dust collection path (148).

[0293] The dust bag drawer (144) is coupled to be withdrawable from the dust collection housing (141), and a dust bag (not shown) can be accommodated inside.

[0294] At this time, referring to FIG. 17, the dust bag drawer (144) includes a dust bag drawer body (144a), a handle (144d), and a drawer rail (144e).

[0295] The dust bag drawer body (144a) may provide a space for a dust bag (not shown) to be attached inside. For example, the dust bag drawer body (144a) may be formed in the shape of a box with an open top, and the rear may have a dust inlet (144b) and an air outlet (144c) formed so as to be in communication with the first dust collection channel (147) and the second dust collection channel (148).

[0296] For example, the dust bag drawer body (144a) may be formed with different left-right widths on the upper side and lower side. For example, the left-right width on the upper side of the dust bag drawer body (144a) may be formed to be larger than the left-right width on the lower side. That is, the interior of the dust bag drawer body (144a) may be formed in a stepped manner. Through this, the upper space where the dust bag (not shown) is provided can be maximized, and a flow path can be formed to facilitate the air passing through the dust bag (not shown) escaping downwards.

[0297] The upper side of the dust bag drawer body (144a) may be connected to the first dust collection path (147) through the dust inlet (144b). The dust inlet (144b) may be configured to guide air flowing through the first dust collection path (147) into the interior of the dust bag (not shown). The dust inlet (144b) may be connected to the first dust collection path (147) and the dust bag (not shown). Thus, dust sucked in from the dust bin (220) of the robot vacuum cleaner (200) can move into the interior of the dust bag (not shown) through the first dust collection path (147) and the dust inlet (144b).

[0298] The dust bag drawer (144) may be connected to the second dust collection path (148) through an air outlet (144c) formed on the lower side. The air outlet (144c) may be configured to guide air passing through the dust bag drawer (144) to the second dust collection path (148). The air outlet (144c) may be positioned at a different height from the dust inlet (144b). The air outlet (144c) may be positioned lower than the dust inlet (144b). The air outlet (144c) may be connected to the internal space of the dust bag drawer (144) and the second dust collection path (148). Thus, air that has been filtered of dust while passing through a dust bag (not shown) may move to the second dust collection path (148) via the air outlet (144c).

[0299] A handle (144d) may be provided on 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 hinged to the front surface of the dust bag drawer body (144a), and a gripping part formed by connecting the pair of connecting parts so that a user can grip it.

[0300] With this configuration, when a user grasps the gripper and pulls it forward, the dust bag drawer body (144a) can be pulled forward together and withdrawn. Accordingly, according to the present invention, a user can easily pull the dust bag drawer (144) forward and then lift the dust bag (not shown) upward to remove and replace it.

[0301] Drawer rails (144e) may be formed on the left and right sides of the dust bag drawer body (144a). The drawer rails (144e) can guide the movement of the dust bag drawer body (144a).

[0302] For example, the drawer rail (144e) may be formed in the shape of a groove or rib along the front-rear direction on the left-right side of the dust bag drawer body (144a).

[0303] With this configuration, when a user attaches the dust bag drawer (144) to the dust collection 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.

[0304] Meanwhile, a rail (not shown) may also be formed on the inner surface of the dust collection housing (141) corresponding to the drawer rail (144e). The rail (not shown) of the dust collection 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 (not shown) of the dust collection housing (141) may be formed in a rib or protruding jaw shape.

[0305] Meanwhile, the robot vacuum cleaner station (100) may include a dust collection path. The dust collection path may refer to a path through which air sucked in through the dust passage hole (123a) flows through the dust bag to the dust collection motor (145).

[0306] Specifically, the dust collection path may include a first dust collection path (147) that connects the dust bin (220) and the internal space of the dust collection housing (141) when the robot vacuum cleaner (200) is connected to the robot vacuum cleaner station (100) and the dust passage hole (123a) and the dust bin (220) of the robot vacuum cleaner (200) are connected, and a second dust collection path (148) that connects the internal space of the dust collection housing (141) and the dust collection motor (145).

[0307] The first dust collection channel (147) can connect the dust bin (220) of the robot vacuum cleaner (200) and the internal space of the dust collection housing (141). The first dust collection channel (147) can connect the dust bin (220) of the robot vacuum cleaner (200) and the internal space of the dust collection housing (141). The first dust collection channel (147) can connect the dust passage hole (123a) of the seating portion (120) and the internal space of the dust collection housing (141). The first dust collection channel (147) may refer to the space between the dust bin (220) of the robot vacuum cleaner (200) and the dust collection housing (141). The first dust collection channel (147) may be formed close to the horizontal direction. The first dust collection channel (147) may be a space formed towards the rear from the dust passage hole (123a), or it may be a channel formed by bending toward the side from the dust passage hole (123a) so that dust and air can flow through it. Dust inside the dust bin (220) of the robot vacuum cleaner (200) can move into the internal space of the dust collection housing (141) through the first dust collection channel (147).

[0308] A dust inlet (141a) may be positioned on the rear side of the dust collection housing (141). The first dust collection path (147) and the dust collection housing (141) may be connected through the dust inlet (141a). The dust inlet (141a) may be combined with a dust bag (not shown). Air containing dust from the dust bin (220) of the robot vacuum cleaner (200) may pass through the dust inlet (141a) and be collected in the dust bag (not shown). Additionally, the dust inlet (141a) may be positioned at the same location as the dust inlet (144b) of the dust bag drawer (144) while combined with the dust bag drawer (144).

[0309] The dust inlet (141a) may include a rubber stopper covering the dust inlet (141a). The rubber stopper may be rotatably coupled to the dust inlet (141a). When air is introduced into the dust inlet (141a), the rubber stopper may rotate to allow the air to pass through. When air is not introduced into the dust inlet (141a), the rubber stopper may remain covering the dust inlet (141a). Through this configuration, it is possible to prevent air inside the dust collection housing (141) from flowing back toward the first dust collection path (147).

[0310] The second dust collection channel (148) can connect the internal space of the dust collection housing (141) and the dust collection motor (145). The second dust collection channel (148) can be formed close to the horizontal direction. At this time, the first dust collection channel (147) and the second dust collection channel (148) can be formed at different heights. The first dust collection channel (147) and the second dust collection channel (148) can be formed in a stacked structure. The second dust collection channel (148) can be positioned lower than the first dust collection channel (147). With such a configuration, the width in the left-right direction and the overall volume of the robot vacuum cleaner station (100) can be minimized.

[0311] The air outlet (141b) may be positioned on the rear side of the dust collection housing (141). The second dust collection path (148) and the dust collection housing (141) may be connected through the air outlet (141b). The air outlet (141b) may be positioned below the dust inlet (141a). Additionally, the air outlet (141b) may be positioned at the same location as the air outlet (144c) of the dust bag drawer (144) when combined with the dust bag drawer (144).

[0312] The dust collection module can provide a suction airflow to the dust collection path.

[0313] Specifically, the dust collection module may include a dust collection motor housing (146) and a dust collection motor (145).

[0314] The dust collection motor housing (146) can be placed inside the housing (110). The dust collection motor housing (146) can accommodate a dust collection motor (145) inside.

[0315] The internal space of the dust collection motor housing (146) can be connected to the second dust collection path (148). Thus, air flowing through the second dust collection path (148) can be guided to the dust collection motor (145).

[0316] The internal space of the dust collection motor housing (146) can be connected to a circulation path. Thus, air passing through the dust collection motor (145) can be guided to the circulation path.

[0317] The dust collection motor (145) can generate suction force in the dust collection path.

[0318] The dust collection motor (145) can be positioned at the rear of the dust collection housing (141). By doing so, the dust collection motor (145) can provide suction power to suck up dust inside the dust bin (220) of the robot vacuum cleaner (200).

[0319] The dust collection motor (145) can generate suction force by rotation. For example, the dust collection motor (145) can be formed in a shape similar to a cylinder.

[0320] One side of the dust collection motor (145) may be connected to the second dust collection path (148), and the other side may be connected to the circulation path. When the dust collection motor (145) is driven, air flowing through the second dust collection path (148) may be introduced into the interior of the dust collection motor housing (146). Additionally, the air introduced into the interior of the dust collection motor housing (146) may pass through the dust collection motor (145), then flow through the circulation path and be exhausted to the air return port (125b).

[0321] Meanwhile, the rotation axis of the dust collection motor (145) can be formed close to the horizontal direction. With this configuration, the overall volume of the robot vacuum cleaner station (100) placed in the kitchen cabinet (2) or the mounting space (21a) of the structure can be minimized.

[0322] Meanwhile, according to an embodiment, the rotation axis of the dust collection motor (145) may be arranged along the vertical direction. In this case, the horizontal space occupied by the dust collection motor (145) can be minimized.

[0323] The air circulation unit (125) can guide the air discharged from the dust collection motor (145) to the robot vacuum cleaner (200).

[0324] The air circulation section (125) may be composed of a circulation path and an air circulation port (125b).

[0325] The circulation path can provide a path through which air discharged from the dust collection motor (145) flows. The circulation path can be placed inside the base body (121a).

[0326] The circulation path may be connected to the dust collection motor (145) via a path. The circulation path may refer to a path connecting the internal space of the motor housing (151) and the air return port (125b). One end of the circulation path may be in communication with the internal space of the dust collection motor housing (146), and the other end of the circulation path may be in communication with the receiving space of the recess (121da).

[0327] The circulation path may be a path formed along a horizontal direction inside the housing (110). The circulation path may be connected to the dust collection motor (145). Specifically, one end of the circulation path may be in communication with the internal space of the dust collection motor housing (146), and the other end of the circulation path may be in communication with the air return port (125b).

[0328] The air circulation port (125b) can serve as an outlet to guide the air discharged from the dust collection motor (145) into the receiving space of the recess (121da).

[0329] An air circulation port (125b) may be formed in the base (121). An air circulation port (125b) may be formed in the agitator receiving portion (121d). An air circulation port (125b) may be formed in the side wall of the recess (121da).

[0330]

[0331] The circulation path according to an embodiment of the present invention can guide air discharged from a dust collection motor (145) to the suction part (211) of a robot vacuum cleaner (200).

[0332] The circulation path can be designed so that the air discharged from the dust collection motor (145) is guided to the suction part (211) of the robot vacuum cleaner (200) without being discharged to the outside, thereby creating a structure in which the air continuously circulates between the robot vacuum cleaner (200) and the robot vacuum cleaner station (100). As a result, the heat discharged from the dust collection motor (145) is not discharged to the kitchen cabinet (2) but is recirculated back into the interior of the robot vacuum cleaner (200), thus preventing damage to the interior of the kitchen cabinet (2).

[0333] Air passing through the dust collection motor (145) is discharged into the receiving space (S) through the air return port (125b), and the air discharged into the receiving space (S) can be recirculated into the suction part (211) due to the suction force of the dust collection motor (145). Accordingly, air sucked from the dust bin (220) by the suction force of the dust collection motor (145) can be discharged into the receiving space (S) after flowing in sequence through the dust passage hole (123a), the first dust collection path (147), the dust collection housing (141), the second dust collection path (148), the dust collection motor (145), the circulation path, and the air return port (125b).

[0334] At this time, the dust collection motor (145) can be driven together with the suction motor (not shown) of the robot vacuum cleaner (200). Since the air exhausted through the air circulation port (125b) is sucked into the suction part (211) by the suction force of the suction motor (not shown) in addition to the dust collection motor (145), it has the effect of improving dust collection efficiency.

[0336] Mop washing section

[0337]

[0338] FIG. 15 shows an enlarged view illustrating a mop washing section of a robot vacuum cleaner station according to an embodiment of the present invention, FIG. 16 shows an enlarged view illustrating a washing water supply section of a mop washing section of a robot vacuum cleaner station according to an embodiment of the present invention, and FIG. 17 shows a drawing illustrating a state in which a dust collection section and a detergent container are withdrawn from a robot vacuum cleaner station according to an embodiment of the present invention.

[0339] Referring to FIGS. 15 to 17, the mop washing unit (160) of the robot vacuum cleaner station (100) according to an embodiment of the present invention is described as follows.

[0340] A robot vacuum cleaner station (100) according to an embodiment of the present invention may include a mop washing unit (160). The mop washing unit (160) can wash the mop (242) of a robot vacuum cleaner (200) coupled to a seating unit (120).

[0341] The mop washing unit (160) may include a washing water supply unit (161) that discharges washing water onto a washing plate (122), a detergent container (163) in which a liquid containing detergent is stored, and a wastewater container (164) in which washing water is stored after washing the mop (242) is finished.

[0342] In the washing water supply unit (161), purified water and detergent are mixed to produce washing water for washing the rag (242).

[0343] 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).

[0344] At this time, a pair of wash water discharge ports (161e) may be spaced apart and positioned on the rear side of the connecting wall (123). The wash water discharge ports (161e) may discharge wash water from the upper side of the wash plate (122) toward the wash plate (122). For example, a pair of wash water discharge ports (161e) may be positioned on the upper side of a pair of wash protrusions (122a).

[0345] 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 branching path (161a) and connected to each spaced-apart wash water discharge port (161e). That is, the branching path (161a) can be formed in a shape where one pipe is branched into two, and at this time, one end of the branch is connected to one of the pair of wash water discharge ports (161e), and the other end of the branch is connected to the other of the pair of wash water discharge ports (161e). Accordingly, the branching path (161a) can supply wash water to the pair of wash water discharge ports (161e).

[0346] The washing water discharge port (161e) may be formed integrally with the connecting wall (123) at the rear side of the connecting wall (123) or may be detachably connected to the connecting wall (123).

[0347] The purified water inlet (161b) is configured to guide purified water supplied from the water supply pipe of the kitchen cabinet (2) to the washing water supply unit (161). Specifically, the water supply pipe of the kitchen cabinet (2) is connected to a regulator (162) so that the flow rate supplied from the water supply pipe can be regulated. Additionally, a portion of the purified water passing through the regulator (162) is supplied to the water tank (230) of the robot vacuum cleaner (200) through the water supply nozzle (123c), and the remainder can be introduced through the purified water inlet (161b) to a pair of washing water supply units (161) spaced apart from each other.

[0348] The detergent inlet (161c) is configured to guide the liquid containing detergent supplied from the detergent container (163) to the washing water supply unit (161). Specifically, the liquid containing detergent stored in the detergent container (163) can be supplied to the washing water supply unit (161) through the detergent pump (161d).

[0349] Additionally, the detergent and purified water introduced into the washing water supply unit (161) can be mixed and used as washing water. The washing water supply unit (161) can discharge washing water onto 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 rag (242) placed on the washing plate (122).

[0350] The detergent container (163) can store a liquid containing detergent.

[0351] The detergent container (163) includes a detergent container body (163a), a handle (163b), and a detergent container rail (163c) (see drawing).

[0352] The detergent container body (163a) can provide a space for storing a liquid containing detergent. For example, the detergent container body (163a) can be formed in the shape of a box with an open top, and the rear can be connected to a washing water supply unit (161).

[0353] A handle (163b) may be provided on the front of the detergent container body (163a). The handle (163b) may be provided so that a user can grip it. For example, the handle (163b) may include a pair of connecting parts hinged to the front surface of the detergent container body (163a) and a gripping part formed by connecting the pair of connecting parts so that a user can grip it.

[0354] With this configuration, when a user grasps the gripper 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.

[0355] 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) can guide the movement of the detergent container body (163a).

[0356] For example, the detergent container rail (163c) may be formed in the shape of a groove or rib along the front-rear direction on the left-right side of the detergent container body (163a).

[0357] With this configuration, when a user attaches the detergent container (163) to the housing (110), it can be attached in the correct position and prevent the washing water from leaking out.

[0358] Meanwhile, although not shown, a rail may be formed on the housing (110) corresponding to the detergent container rail (163c). The rail may be formed corresponding to the shape and position of the detergent container rail (163c).

[0359] The wastewater tank (164) can provide a space for storing the washing water used to wash the mop (242). After the washing of the mop (242) is finished, the washing water discharged onto the upper surface of the washing plate (122) can be drained into the passage hole (122b) while descending along the slope of the washing plate (122). The washing water that passes through the passage hole (122b) accumulates in the washing tank (128). Additionally, the washing water accumulated in the washing tank (128) can flow into the wastewater suction path (164b) through the wastewater inlet (164c) and can flow into the wastewater tank (164) by passing through the wastewater inlet path (164b). That is, the liquid that passes through the washing plate (122) can flow along the washing tank (128) and be discharged through the wastewater inlet (164c).

[0360] Meanwhile, the sewage suction channel (164b) is formed in the 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 the 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 channel (164b) may be arranged on the lower side of the outside air supply module (171). Additionally, the sewage suction channel (164b) may be arranged on the lower side of the outside air supply channel (171a).

[0361] The washing water stored in the wastewater tank (164) can be drained into 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 into the drain pipe by flowing through the wastewater discharge path (164a) by a centrifugal pump (not shown).

[0362] The wastewater discharge path (164a) connected to the wastewater tank (164) can be connected upstream (25b) based on the U-trap (25a) of the drain pipe (25) of the kitchen cabinet (2). This is because if the wastewater discharge path (164a) is connected downstream (25c) based on the U-trap (25a) of the drain pipe (25), odors or fluid inside the drain pipe (25) may flow back into the wastewater discharge path (164a).

[0363] Additionally, the mop washing unit (160) may include a check valve (not shown). The check valve can prevent fluid inside the drain pipe (25) from flowing back into the wastewater discharge path (164a). The check valve may be provided at the other end of the wastewater discharge path (164a) connected to the drain pipe (25).

[0364] Meanwhile, the detergent container (163) and the wastewater 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 wastewater 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.

[0366] Mop drying section

[0367]

[0368] FIG. 18 shows a perspective view illustrating a mop drying section of a robot vacuum cleaner station according to an embodiment of the present invention, FIG. 19 shows an enlarged view of a mop drying section of a robot vacuum cleaner station according to an embodiment of the present invention, and FIG. 20 shows a cross-sectional view illustrating air flow into a heat supply module according to an embodiment of the present invention.

[0369] Referring to FIGS. 18 to 20, a robot vacuum cleaner station (100) according to one embodiment of the present invention may include a mop drying unit (170). At this time, the mop drying unit (170) can dry the mop (242) of the robot vacuum cleaner (200) that has been washed by the mop washing unit (160) or the mop (242) that is wet after a water cleaning operation is finished.

[0370] 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), a circulation fan (173), and a check valve (175).

[0371] 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 section (171c), a heater (171d), and a blower fan (171e).

[0372] An external air supply channel (171a) is formed in the external air supply module (171). The external air supply channel (171a) can flow external air to the external air discharge section (171c).

[0373] The external air supply channel (171a) can connect the external space of the housing (110) with the receiving space (S). One side of the external air supply channel (171a) can be in communication with the external space through the external air inlet (171b), and the other side of the external air supply channel (171a) can be in communication with the receiving space (S) through the external air discharge section (171c).

[0374] An external air inlet (171b) may be formed on the rear side of the housing (110). Multiple external air inlets (171b) may be formed on the rear side of the housing (110). Air from outside the housing (110) may flow into the external air supply path (171a) through the external air inlet (171b). Thus, air from outside the housing (110) may flow into the interior of the housing (110).

[0375] At least a portion of the external air discharge section (171c) may be positioned above the washing plate (122). The external air discharge section (171c) may be open in a direction facing the washing plate (122). A pair of external air discharge sections (171c) may be provided in a state where they are open downwards.

[0376] The outside air discharge section (171c) can discharge air that has passed through the outside air supply path (171a). The outside air discharge section (171c) can discharge air heated by the heater (171d). For example, an outside air discharge port may be formed in the outside air discharge section (171c).

[0377] With the mop (242) seated on the cleaning plate (122), the external air discharge section (171c) can be opened toward the upper side of the mop (242). Thus, the external air discharge section (171c) is positioned adjacent to the mop (242) and is opened downward, allowing air discharged from the external air discharge section (171c) to flow toward the mop (242).

[0378] A blower fan (171e) is positioned on an outside air supply path (171a) and can blow air toward a receiving space (S). When the blower fan (171e) is driven, air introduced through the outside air inlet (171b) is heated by a heater (171d) and can be discharged into the receiving space (S) through the outside air discharge section (171c).

[0379] A heater (171d) is positioned on an 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 section (171c).

[0380] The heater (171d) may include a heater housing and a heating element. In this case, the heater housing may be placed on an external air supply path (171a), and a space may be provided inside to accommodate a heating element. Additionally, the heating element may heat the air flowing into the heater housing. Thus, the air heated by the heating element is discharged into the receiving space (S) through the external air discharge section (171c) to dry the wet rag (242).

[0381] The air exhaust unit (172) can discharge the hot and humid air inside the robot vacuum cleaner station (100) generated while drying the mop (242) into 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).

[0382]

[0383] An air discharge channel may be formed in the air discharge section (172). At this time, one end of the air discharge channel may be connected to a receiving space (S), and the other end may be connected to a drain pipe (25). Specifically, the air intake port (172a), which is one end of the air discharge channel, may be connected to the receiving space (S), and the air discharge port (172b), which is the other end, may be connected to the drain pipe (25).

[0384] Meanwhile, the air intake (172a) can be positioned at various locations on the receiving space (S). For example, the air intake (172a) can be positioned on the connecting wall (123). For another example, the air intake (172a) can be positioned on the inner wall (124). For yet another example, the air intake (172a) can be positioned higher than the ground than the mop (242) but positioned in front of the outside air discharge section (171c). Through this, air containing steam generated during the drying process of the mop (242) can be discharged.

[0385] The air exhaust section (172) can be connected downstream (25c) relative to the U-trap (25a) of the drain pipe (25) of the kitchen cabinet (2). This is because if the air exhaust section (172) is connected upstream (25b) relative to the U-trap (25a) of the drain pipe (25), the heat exhausted through the air exhaust section (172) may not be able to pass through the drain pipe (25) due to the water accumulated in the U-trap (25a).

[0386] Meanwhile, according to one embodiment of the present invention, the air discharge channel may have a single pipe branched into two inside the housing (110) and penetrate both sides of the housing (110). At this time, one of the branches penetrates the left outer wall surface of the housing (110), and the other branch penetrates the right outer wall surface of the housing (110). The air discharge section (172) that penetrates both outer walls (111) of the housing (110) may be connected to the drain pipe (25). Accordingly, air sucked in from the air discharge section (172) may flow through the air discharge outlets (172b) branched to both sides and be exhausted downstream (25c) relative to the U-trap (25a) of the drain pipe (25).

[0387] The circulation fan (173) can exhaust air introduced through the air intake (172a) into the drain pipe (25). The circulation fan (173) can cause air flow into the air discharge section (172). The circulation fan (173) can be placed on the air discharge flow path section.

[0388] When the circulation fan (173) is driven, air in the receiving space (S) can be drawn into the air intake (172a). The air drawn into the air intake (172a) can flow through the air discharge section (172) and be exhausted into the drain pipe (25). Specifically, the air flowing through the air discharge section (172) when the circulation fan (173) is driven can be exhausted downstream (25c) relative to the U-trap (25a) of the drain pipe (25).

[0389] The rag drying section (170) may include a check valve (175). The check valve (175) may be provided at the other end of the air discharge passage connected to the drain pipe (25). Through this, the fluid inside the drain pipe (25) can be prevented from flowing back into the air discharge section (172).

[0390]

[0391] Layout

[0392]

[0393] FIGS. 21 and 22 illustrate a diagram illustrating the arrangement relationship of a robot vacuum cleaner station on a horizontal plane according to an embodiment of the present invention.

[0394] With reference to FIGS. 4, FIGS. 21 and FIGS. 22, the arrangement of a robot vacuum cleaner station (100) according to an embodiment of the present invention is described as follows.

[0395] A robot vacuum cleaner station (100) according to an embodiment of the present invention is characterized by being installed in the lower space of a kitchen cabinet (2).

[0396] To this end, the robot vacuum cleaner station (100) according to an embodiment of the present invention is characterized by being positioned along a horizontal direction in alignment with the space formed between the lower plate (23) of the kitchen cabinet (2) and the floor of the kitchen.

[0397] Specifically, in the robot vacuum cleaner station (100) according to an embodiment of the present invention, a dust collection unit (140) and / or a mop washing unit (160) may be positioned on the side of the entrance (127).

[0398] At this time, when both the dust collection unit (140) and the mop washing unit (160) are provided, the seating unit (120) may be positioned between the dust collection unit (140) and the mop washing unit (160).

[0399] For example, an entrance (127) and a door (126) may be positioned at the front of the robot vacuum cleaner station (100). Additionally, a seating area (120) to which the robot vacuum cleaner (200) is coupled may be positioned from the entrance (127) to the rear. At this time, a dust collection unit (140) may be positioned from the front of the robot vacuum cleaner station (100) to the rear by a predetermined length. Furthermore, a mop washing unit (160) may also be positioned from the front of the robot vacuum cleaner station (100) to the rear by a predetermined length.

[0400] Accordingly, when looking at the robot vacuum cleaner station (100) from the front outer side of the robot vacuum cleaner station (100), the front of the dust collection unit (140) and / or the front of the mop washing unit (160) may be positioned on the left and right sides of the entrance (127).

[0401] At this time, the dust bag (not shown) of the dust collection unit (140) may be provided so as to be pulled out to the front of the housing (110). In addition, the detergent container (163) of the mop washing unit (160) may be provided so as to be pulled out to the front of the housing.

[0402] That is, a handle (144d) may be provided at the front end of the dust collection unit (140) so that a user can grasp the dust collection unit housing (141). Additionally, a handle (163b) may be provided at the front end of the mop washing unit (160) so that a detergent container (163) can be pulled.

[0403] With this configuration, when a user wants to retrieve a dust bag (not shown) or a detergent container (163), the user can immediately recognize the location of the retrieval and can retrieve the dust bag (not shown) or the detergent container (163) with just a simple motion of pulling the handle, thereby providing convenience.

[0404] Meanwhile, the rear end of the dust collection housing (141) and the detergent container (163) may be positioned at a predetermined distance from the rear end of the housing (110). Additionally, a dust collection motor (145) may be positioned between the rear end of the dust collection housing (141) and the rear end of the housing (110). With this configuration, it is easy to connect the wires supplying power to the dust collection motor (145). Furthermore, there is an effect of minimizing the total space occupied by the mounting part (120), the dust collection housing (141), and the dust collection motor (145) within a limited space.

[0405] Additionally, between the rear end of the housing (110) and the rear end of the detergent container (163), at least a flow path through which washing water for washing the mop (242) can flow and a pump providing the flow force of the washing water may be partially arranged. With this configuration, the path through which washing water flows from the water supply pipe can be shortened. Furthermore, within a limited space, the total space occupied by the seating portion (120), the mop detergent container (163), and the flow path through which washing water flows can be minimized.

[0406]

[0407] Meanwhile, the robot vacuum cleaner station (100) may have a mop drying section (170) positioned behind the seating section (120). At this time, the mop drying section (170) may be positioned between the rear end of the seating section (120) and the rear end of the housing (110).

[0408] Accordingly, in the robot vacuum cleaner station (100) according to an embodiment of the present invention, a dust collection unit (140) and a mop washing unit (160) are arranged on the left and right sides based on the seating unit (120), and a mop drying unit (170) can be arranged on the rear side.

[0409] That is, in the robot vacuum cleaner station (100) according to an embodiment of the present invention, a dust collection unit (140), a mop washing unit (160), and a mop drying unit (170) can all be arranged within a predetermined distance range from the outer edge of the seating unit (120).

[0410] Through this arrangement, the seating section (120), dust collection section (140), mop washing section (160), and mop drying section (170) can all be arranged in the narrowest space on the horizontal plane.

[0411] This has the effect of minimizing flow path loss by shortening the distance between the dust bin (220) and the dust collection unit (140) of the robot vacuum cleaner (200). Additionally, by minimizing the distance between the mop (242) and the mop washing unit (160) of the robot vacuum cleaner (200) and the distance between the mop (242) and the mop drying unit (170) of the robot vacuum cleaner (200), it has the effect of limiting the range where washing water and wastewater from washing are present.

[0412] In addition, by this arrangement, the robot vacuum cleaner station (100) of the present invention can arrange all components within a limited height.

[0413] Specifically, based on the state in which the robot vacuum 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 vacuum cleaner (200). Additionally, at least a portion of the mop washing portion (160) may be positioned lower than the top of the robot vacuum cleaner (200). Additionally, at least a portion of the mop drying portion (170) may be positioned lower than the top of the robot vacuum cleaner (200).

[0414] Additionally, based on the state in which the robot vacuum cleaner (200) is coupled to the mounting portion (120), the top of the robot vacuum cleaner (200) may be positioned higher than the dust bag drawer (144). Additionally, the top of the robot vacuum cleaner (200) may be positioned higher than the detergent container (163). Additionally, the top of the dust bag drawer (144) may be positioned higher than the detergent container (163).

[0415] As a result, the robot vacuum cleaner station (100) according to an embodiment of the present invention may have a dust collection unit (140), a mop washing unit (160), and a mop drying unit (170) arranged on three sides surrounding the seating unit (120), excluding the front side where the robot vacuum cleaner (200) enters. With such arrangement, even in situations where the height in the vertical direction is limited, it is possible to charge the robot vacuum cleaner (200) using a minimum horizontal space, as well as collect dust from the robot vacuum cleaner (200), wash the mop (242), and dry the mop (242).

[0416]

[0417] drawer

[0418]

[0419] When a charging station for a robot vacuum is placed at the bottom of a kitchen cabinet, it minimizes external exposure, which can provide an interior design effect. However, there is a limitation in that if the robot vacuum breaks down while it is inside the kitchen cabinet or if the charging station for the robot vacuum breaks down, it may be difficult for the user to take it out and repair it. To solve this, the present invention may add a drawer (190) to the robot vacuum station (100).

[0420] In this regard, FIG. 23 illustrates a state in which a drawer is provided in a robot vacuum cleaner station according to an embodiment of the present invention, and FIG. 24 illustrates a state in which a drawer is withdrawn in a robot vacuum cleaner station according to an embodiment of the present invention.

[0421] Referring to FIGS. 23 and 24, a drawer (190) of a robot vacuum cleaner station (100) according to one embodiment of the present invention is described as follows.

[0422] A robot vacuum cleaner station (100) according to one embodiment of the present invention may further include a drawer (190) that is drawn out of a housing (110).

[0423] When the drawer (190) is inserted into the housing (110), the door (126) can be closed when the robot vacuum cleaner (200) enters the seating portion (120). In this case, the inside and outside of the housing (110) can be blocked by the door (126) for the robot vacuum cleaner (200).

[0424] As a result, the robot vacuum cleaner (200) can prevent dust from scattering outside the robot vacuum station (100) while dust collection is performed on the dust bin (220) inside the housing (110). Additionally, it can prevent wastewater from leaking outside the robot vacuum station (100) while cleaning of the mop (242) is performed.

[0425] 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).

[0426] At this time, the drawer (190) can be pulled out with the seating portion (120) provided inside. With this configuration, when the drawer (190) is pulled out, the seating portion (120) and / or the robot vacuum cleaner (200) can be pulled out from the kitchen cabinet (2).

[0427] At this time, when the drawer (190) is withdrawn from the housing (110) while the door (126) is closing the entrance (127), the robot vacuum cleaner (200) placed in the seating portion (120) can be exposed to the outside.

[0428] Accordingly, according to the present embodiment, when maintenance such as repair or cleaning is required of the robot vacuum cleaner station (100), the user can easily pull out the mounting portion (120) and / or the robot vacuum cleaner (200) through the drawer (190) to expose the internal components of the robot vacuum cleaner station (100) or the robot vacuum cleaner (200).

[0429] Meanwhile, a drawer (190) according to one embodiment of the present invention can be withdrawn with a dust collection unit (140) provided inside. That is, the drawer (190) can be withdrawn together with the dust collection unit (140).

[0430] 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) may be parallel to the direction in which the drawer (190) is withdrawn. For example, the withdrawal direction of the dust bag drawer (144) may be parallel to the withdrawal direction of the drawer (190).

[0431] Additionally, a drawer (190) according to one embodiment of the present invention may be withdrawn with at least a portion of a mop washing unit (160) provided inside. That is, the drawer (190) may be withdrawn together with at least a portion of the mop washing unit (160). For example, the drawer (190) may be withdrawn together with a detergent container (163) and a wastewater container (164).

[0432] 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) may be parallel to the direction in which the drawer (190) is withdrawn.

[0433] With this configuration, the robot vacuum 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) all having parallel drawing directions.

[0434] Therefore, the user can easily recognize the direction of withdrawal of the components of the robot vacuum cleaner station (100) of the present invention, and can easily withdraw them for repair and maintenance.

[0435]

[0436] The drawer (190) includes a drawer side wall (191), a fitting part (192), and a drawer rail (193).

[0437] The drawer side wall (191) is provided to be movable relative to the outer wall surface of the housing (110). For example, a pair of drawer side walls (191) may be arranged to face a pair of outer wall surfaces of the housing (110).

[0438] At this time, a pair of drawer side walls (191) may be positioned on the inner side of the robot vacuum cleaner station (100) rather than on the outer wall surface of a pair of housings (110). That is, a pair of drawer side walls (191) may be positioned closer to the seating portion (120) than on the outer wall surface of a pair of housings (110).

[0439] At this time, a pair of drawer side walls (191) can be directly connected to the base (121) of the seating portion (120). Alternatively, a pair of drawer side walls (191) can be connected by a drawer base (not shown), and it is also possible for the seating portion (120) to be coupled to the upper side of the drawer base (not shown) and to move together.

[0440] Meanwhile, a dust collection unit (140) and / or a mop washing unit (160) may be disposed between the drawer side wall (191) and the seating unit (120). That is, based on the state in which the robot vacuum cleaner (200) is coupled to the seating unit (120), a dust collection unit (140) and / or a mop washing unit (160) may be disposed between the robot vacuum cleaner (200) and the drawer side wall (191).

[0441] With this configuration, the dust collection unit (140) and the mop washing unit (160) can be arranged by utilizing the minimum horizontal space.

[0442] A fitting part (192) is provided on the drawer side wall (191), and at least one of a hose and a wire is detachably connected. For example, the fitting part (192) is positioned on the drawer side wall (191), and a hose and / or a wire can be connected.

[0443] The fitting part (192) is coupled to the drawer side wall (191), one side of the fitting part (192) is positioned in the inner space of the drawer (190) rather than the drawer side wall (191), and the other side of the fitting part (192) is positioned outside the drawer side wall (191).

[0444] 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 is connected to which air inside the drawer (190) is discharged, and a power connection part to which a power source is connected.

[0445] At this time, the water supply pipe of the mop washing unit (160) and the water supply pipe connected from an external water source can be connected to each of the two sides of the water supply pipe connection. Additionally, the drain pipe of the mop washing unit (160) and the drain pipe connected to the upstream (25b) of the kitchen cabinet (2) can be connected to each of the two sides of the drain pipe connection.

[0446] That is, the fitting part (192) of the present invention may be a structure that allows the water supply pipe and drain pipe for direct drainage using the water supply source and drain pipe provided in the kitchen cabinet (2) to be detachably connected to the water supply pipe and drain pipe inside the robot vacuum cleaner station (100).

[0447] Additionally, air exhaust pipes connected from the air outlet (172b) of the rag drying unit (170) can be connected to each side of the exhaust pipe connection.

[0448] Accordingly, the air discharged from the rag drying section (170) can be exhausted downstream (25c) of the U-trap.

[0449] In addition, a wire can be connected to the power connection part to connect an external power source. At this time, the wire can be connected not only directly to the power connection part, but also using wire connection means such as a connector or adapter.

[0450] A drawer rail (193) is positioned on a drawer side wall (191) and can guide the movement of the drawer side wall (191). The drawer rail (193) may be fixedly coupled to or integrally formed with the drawer side wall (191) and may be coupled 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 a rail is provided on the drawer (190) and the housing (110), it is not necessarily limited to the form of a rail, and may include all forms such as a roller, guide groove, or guide rib that can replace the rail.

[0481] Dust collection unit sterilization module

[0482]

[0483] FIG. 26 is a drawing illustrating the arrangement of a dust collection unit sterilization module in a robot vacuum cleaner station according to an embodiment of the present invention. FIG. 27 is a drawing illustrating the arrangement relationship on the rear side of a dust collection unit housing in a robot vacuum cleaner station according to an embodiment of the present invention. FIG. 28 is a drawing illustrating a dust collection unit sterilization module in a robot vacuum cleaner station according to an embodiment of the present invention.

[0484] Referring to FIGS. 26 to 28, a dust collection unit sterilization module (130) of a robot vacuum cleaner station (100) according to one embodiment of the present invention will be described below.

[0485] The housing (110) can accommodate a dust collection unit (140) for emptying dust from the robot vacuum cleaner inside. The dust collection unit (140) can collect dust from the dust bin (220) of the robot vacuum cleaner (200).

[0486] A dust collection unit (140) according to one embodiment of the present invention 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) may form a space capable of accommodating a dust bag (not shown) inside. The dust collection space may refer to the internal space of the dust collection unit housing (141).

[0487]

[0488] Meanwhile, if a long time passes while unsterilized foreign matter is collected in the dust collection unit (140), insects and microorganisms may multiply. In particular, mites such as grain mites are microorganisms that parasitize grains that are not sufficiently dried, and if grains are collected in the dust collection unit (140) in a high-temperature and high-humidity environment, they can easily multiply and move along the path of the vacuum cleaner station and come out to the outside.

[0489]

[0490] To solve this problem, a robot vacuum cleaner station (100) according to one embodiment of the present invention may include a dust collection unit sterilization module (130) that sterilizes the interior of a dust collection unit housing (141).

[0491] Internal sterilization of the dust collection housing (141) can be performed by circulating heated air or by irradiating the interior with sterilization light. The first, second, and third embodiments of the present invention utilize a hot air circulation method, and the fourth embodiment utilizes a method using sterilization light.

[0492] In an embodiment in which the dust collection housing (141) is sterilized through hot air circulation, the dust collection sterilization module (130) may be defined as a hot air circulation module. The hot air circulation module may be configured to include a circulation fan (130a, 1173, 2173) for discharging air to the dust collection housing (141) and a heater (130d, 1171d, 2171d) for heating the air, and a hot air inlet (141d, 1141d, 2141d) through which the heated air flows into the dust collection housing (141).

[0493] The dust collection unit sterilization module (130) may include a hot air inlet (141d), a hot air outlet (141e), a circulation fan (130a), and a heater (130b).

[0494] The dust collection unit sterilization module (130) is positioned inside the housing (110) and can supply heated air to the dust collection space. The dust collection unit sterilization module (130) can be connected to the dust collection unit housing (141) through a hot air inlet (141d) and a hot air outlet (141e). The heated air through the dust collection unit sterilization module (130) can be introduced into the dust collection space through the hot air inlet (141d). The introduced air can circulate inside the dust collection unit housing (141) and then be discharged through the hot air outlet (141e). Accordingly, the interior of the dust collection unit housing (141) can be sterilized by hot air.

[0495] The dust collection unit sterilization module (130) may be positioned at the rear of the dust collection unit housing (141). The dust collection motor housing (146) may be positioned inside the housing (110) to accommodate the dust collection motor (145) inside. For example, the dust collection motor housing (146) may be positioned at the left rear of the housing (110). The dust collection unit sterilization module (130) may be positioned between the dust collection unit housing (141) and the dust collection motor housing (146).

[0496] Air can be introduced into the dust collector housing (141) through the hot air inlet (141d). The hot air inlet (141d) may be formed on the rear side of the dust collector housing (141). For example, the hot air inlet (141d) may be formed on the lower rear side of the dust collector housing (141). Additionally, the hot air inlet (141d) may be formed on the left rear side of the dust collector housing (141).

[0497] Air introduced from the hot air inlet (141d) can be discharged through the hot air discharge port (141e). In a robot vacuum cleaner station (100) according to one embodiment of the present invention, air introduced through the hot air inlet (141d) can be introduced again into the dust collection unit sterilization module (130). The air can circulate between the dust collection unit sterilization module (130) and the dust collection unit housing (141). The hot air discharge port (141e) can be formed on the rear side of the dust collection unit housing (141). The hot air discharge port (141e) can be formed at a higher position than the hot air inlet (141d) relative to the ground. For example, the hot air discharge port (141e) can be formed on the upper rear side of the dust collection unit housing (141). Additionally, a hot air discharge port (141e) may be formed on the right side of the rear side of the dust collection housing (141).

[0498] Here, the left side refers to the left side when looking forward from inside the robot vacuum cleaner station (100), and the right side may refer to the right side.

[0499]

[0500] Meanwhile, the relationship between the dust collection unit sterilization module (130) and the dust collection unit (140) is explained.

[0501] The dust collection motor (145) can generate an airflow to discharge dust from the dust bin (220) of the robot vacuum cleaner (200) into the dust collection housing (141). A dust collection sterilization module (130) may be placed between the dust collection motor (145) and the dust collection housing (141). The dust collection motor (145) may be placed at the rear of the dust collection sterilization module (130).

[0502] A dust inlet (141a) may be formed on the rear side of the dust collection housing (141). Dust from the dust bin (220) of the robot vacuum cleaner may be introduced into the dust collection housing (141) through the dust inlet (141a). Air formed by the dust collection motor (145) may be introduced into the dust collection housing (141) through the dust inlet (141a).

[0503] An air outlet (141b) may also be positioned on the rear side of the dust collection housing (141). Air introduced into the dust inlet (141a) may be discharged through the air outlet (141b). Specifically, air introduced into the dust inlet (141a) may pass through a dust bag (not shown) and be discharged through the air outlet (141b). The discharged air may flow through the second dust collection path (148) to the dust collection motor housing (146).

[0504] In summary, a dust inlet (141a) and an air outlet (141b) are formed on the rear side of the dust collection housing (141) to collect dust inside the dust bin (220) of the robot vacuum cleaner (200), and a hot air inlet (141d) and a hot air outlet (141e) can be formed to sterilize the inside of the dust collection housing (141).

[0505] For example, the hot air inlet (141d) may be positioned at the lower left, and the hot air outlet (141e) may be positioned at the upper right. In this case, the dust inlet (141a) may be positioned between the hot air inlet (141d) and the hot air outlet (141e).

[0506] That is, the hot air inlet (141d) and the hot air outlet (141e) can be positioned such that the left-right distance between them is maximized on the rear side of the dust collection housing (141). For example, the hot air inlet (141d) and the hot air outlet (141e) can be positioned diagonally on the rear side of the dust collection housing (141). Through this configuration, air introduced into the dust collection housing (141) can circulate inside along a path extended left-right and up-down, and then be discharged to the outside of the dust collection housing (141).

[0507] The circulation fan (130a) can be housed inside the dust collection unit sterilization module (130). The circulation fan (130a) can flow air into the internal space of the dust collection unit housing (141). The circulation fan (130a) can flow air toward the dust collection space. When the circulation fan (130a) is driven, air inside the dust collection unit sterilization module (130) can be introduced into the dust collection space through the hot air inlet (141d).

[0508] The heater (130b) can be housed inside the dust collection unit sterilization module (130). The heater (130b) can heat the air flowing through the circulation fan (130a). The heater (130b) can heat the air flowing into the dust collection space through the hot air inlet (141d). The heater (130b) may include a heater housing and a heating element. In this case, the heater housing may be placed inside the dust collection unit sterilization module (130), and a space may be provided inside the heater housing to house the heating element. The heating element can heat the air flowing into the heater housing.

[0509] According to one embodiment of the present invention, the circulation fan (130a) may be positioned higher than the heater (130b) relative to the ground. Air blown by the circulation fan (130a) may flow to the heater (130b). The air flowing to the heater (130b) is heated and may flow to the dust collection housing (141) through the hot air inlet (141d). The air inside the dust collection housing (141) may be blown again by the circulation fan (130a) and flow to the dust collection sterilization module (130) through the hot air outlet (141e).

[0510] That is, a circulation fan (130a) may be positioned behind the hot air discharge port (141e), and a heater (130b) may be positioned behind the hot air inlet port (141d). The hot air discharge port (141e) may be positioned above the hot air inlet port (141d). Additionally, the circulation fan (130a) may be positioned above the heater (130b). Through this configuration, the heat circulation efficiency can be increased.

[0511] More specifically, air heated by the heater (130b) can be introduced into the lower side of the dust collection housing (141). The heated air moves to the upper side of the dust collection housing (141) according to convection and can flow to the outside of the dust collection housing (141) through a hot air discharge port (141e) positioned higher than the ground than the hot air inlet (141d). Through this configuration, air circulation is achieved, thereby increasing the sterilization efficiency inside the dust collection housing.

[0512] As another example, at least a portion of the dust collection housing (141) may be in communication with the outside. When the circulation fan (130a) is operated, negative pressure may be formed inside the dust collection housing (141). Accordingly, external air may flow into the dust collection housing (141). The air flowing into the dust collection housing (141) may flow to the dust collection sterilization module (130) through the hot air discharge port (141e).

[0513] Meanwhile, a robot vacuum cleaner station (100) according to one embodiment of the present invention may include a dust bag drawer (144). The dust bag drawer (144) may be accommodated inside a dust collection housing (141). The dust bag drawer (144) may be coupled to the dust collection housing (141) so as to be pulled out forward. While the dust bag drawer (144) is accommodated in the dust collection housing (141), it may be connected to a dust collection sterilization module (130). The dust bag drawer (144) may include a hot air inlet and a hot air outlet separately from the dust collection housing (141).

[0514] The hot air inlet may be positioned on the rear side of the dust bag drawer (144). The hot air inlet may be positioned at the same location as the hot air inlet (141d) of the dust collection housing (141) when the dust bag drawer (144) is housed inside the dust collection housing (141).

[0515] The hot air outlet may be positioned on the rear side of the dust bag drawer (144). The hot air outlet may be positioned at the same location as the hot air outlet (141e) of the dust collection housing (141) when the dust bag drawer (144) is housed inside the dust collection housing (141). Thus, the internal space of the dust bag drawer (144) may be connected to the dust collection sterilization module (130) through the hot air inlet and the hot air outlet.

[0516] With the dust bag drawer (144) connected to the dust collection housing (141), heated air can flow into the internal space of the dust bag drawer (144) through the hot air inlet. The air introduced through the hot air inlet can circulate inside the dust bag drawer (144). The air circulated inside the dust bag drawer (144) can flow back to the dust collection sterilization module (130) through the hot air outlet.

[0517] Meanwhile, the rear of the dust bag drawer (144) may be formed with a dust inlet (144b) and an air outlet (144c) so as to be in communication with the first dust collection channel (147) and the second dust collection channel (148). When coupled to the dust collection housing (141), the dust inlet (144b) and the air outlet (144c) of the dust bag drawer (144) may be positioned at the same location as the dust inlet (141a) and the air outlet (141b) of the dust collection housing (141), respectively.

[0518] A dust bag (not shown) is accommodated inside a dust bag drawer (144) and can collect dust inside the dust bin (220) of the robot vacuum cleaner (200). The dust bag (not shown) may be in the shape of a bag with a part open. The open part of the dust bag (not shown) may be detachably connected to the dust inlet (144b) of the dust bag drawer (144). That is, the internal space of the dust bag (not shown) may be in communication with the dust inlet (144b).

[0519] A 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. Air containing dust may flow into the dust bag (not shown) through a dust inlet (144b). At this time, dust that cannot pass through the dust bag (not shown) is collected inside the dust bag (not shown), and the air from which the dust has been filtered may pass through to the outside of the dust bag (not shown). Air that has passed through the dust bag (not shown) may be discharged through an air outlet (144c).

[0520] The internal space of the dust bag drawer (144) can be divided into the internal space of the dust bag (not shown) and the external space of the dust bag (not shown). Air introduced through the hot air inlet of the dust bag drawer (144) can circulate through the internal space of the dust bag drawer (144) containing the dust bag (not shown) and then be discharged through the hot air outlet of the dust bag drawer (144). That is, the hot air inlet and the hot air outlet of the dust bag drawer (144) can be connected to the external space of the dust bag (not shown). As a result, the air heated by the dust collection unit sterilization module (130) can sterilize the dust bag (not shown).

[0521]

[0522] 2nd embodiment

[0523]

[0524] FIG. 29a is a drawing for explaining an external air supply path in a robot vacuum cleaner station according to a second embodiment of the present invention. FIG. 29b is a drawing for explaining a first circulation path in a robot vacuum cleaner station according to a second embodiment of the present invention.

[0525] Referring to FIG. 29a and FIG. 29b, a robot vacuum cleaner station (1100) according to a second embodiment of the present invention is described as follows.

[0526] To avoid repetitive explanations, except for configurations not specifically described in this embodiment, the robot vacuum cleaner station according to one embodiment of the present invention has the same configuration and effect, so it may be used by reference.

[0527]

[0528] The dust collection housing (1141) according to the second embodiment of the present invention may include a hot air inlet (1141d). On the other hand, unlike the first embodiment of the present invention, the dust collection housing (1141) may not include a hot air discharge port.

[0529] A hot air inlet (1141d) may be formed on the rear side of the dust collector housing (1141). For example, the hot air inlet (1141d) may be formed on the lower rear side of the dust collector housing (1141). The hot air inlet (1141d) may be connected to the first circulation path (1130c) to be described later. Air may flow into the interior of the dust collector housing (1141) through the hot air inlet (1141d).

[0530]

[0531] The dust collection unit sterilization module (1130) according to the second embodiment of the present invention may include a first circulation path (1130c) and a first path switching valve (1130d). On the other hand, unlike the first embodiment of the present invention, the dust collection unit sterilization module (1130) may not include a heater and a circulation fan.

[0532] Alternatively, air can be heated by the heater (1171d) and the circulation fan (1173) of the mop drying section (1170). Specifically, the air heated in the mop drying section (1170) can be moved to the receiving space (S) through the outside air supply path (1171a) to dry the mop (242).

[0533] The first Euro switching valve (1130d) operates to separate the mop drying unit (1170) from the outside air supply path (1171a), and the mop drying unit (1170) can be connected to the first circulation path (1130c). At this time, the heated air moves to the dust collection unit housing (1141) and can sterilize the inside thereof.

[0534] That is, in the second embodiment of the present invention, the rag drying unit (1170) can perform not only drying of the rag (242) but also sterilization of the dust collection unit housing (1141).

[0535] The first circulation path (1130c) can connect the mop drying section (1170) and the dust collection housing (1141). The first circulation path (1130c) can be connected to the dust collection housing (1141) through the hot air inlet (1141d). Air heated in the mop drying section (1170) can move to the dust collection housing (1141) through the first circulation path (1130c).

[0536] The first flow switching valve (1130d) may be positioned between the mop drying section (1170), the outside air supply flow path (1171a), and the first circulation flow path (1130c). The first flow switching valve (1130d) may selectively open and close the outside air supply flow path (1171a) and the first circulation flow path (1130c) connected to the mop drying section (1170).

[0537] Specifically, the first Euro switching valve (1130d) can separate the first circulation path (1130c) from the mop drying section (1170) and connect the outside air supply path (1171a) to the mop drying section (1170). Through this, heated air flows into the receiving space (S) and can dry the mop (242) of the robot vacuum cleaner (200).

[0538] Additionally, the first flow switching valve (1130d) can separate the outside air supply flow path (1171a) from the mop drying section (1170) and connect the first circulation flow path (1130c) to the mop drying section (1170). Through this, heated air flows into the dust collection housing (1141) and can sterilize the internal space of the dust collection housing (1141).

[0539]

[0540] Meanwhile, the robot vacuum cleaner station (1100) according to the second embodiment of the present invention may include a dust bag drawer (144) and a dust bag (not shown).

[0541] The dust bag drawer (144) can be pulled out and coupled to the front of the dust collection housing (1141). The dust bag drawer (144) can accommodate a dust bag (not shown) inside. Air heated by the mop drying unit (1170) can be introduced into the interior of the dust bag drawer (144) through the first circulation path (1130c). The air can circulate within the interior space of the dust bag drawer (144) containing the dust bag (not shown) and then be discharged to the outside. Through this, sterilization of the dust bag (not shown) can be achieved.

[0542]

[0543] Meanwhile, the conditions for ending the drying of the rag (242) are explained in detail.

[0544] For example, the first flow switching valve (1130d) can be operated by the control unit (300) when a preset time has elapsed since the drying of the mop (242) began. Specifically, the first flow switching valve (1130d) can be operated by the control unit (300) when 10 minutes have elapsed since the drying of the mop (242) began. At this time, the drying of the mop (242) is stopped, and the sterilization of the dust collection unit housing (1141) can begin.

[0545]

[0546] As another example, the first Euro switching valve (1130d) can be operated by the control unit (300) when the moisture content measured by the sensor (290) is below a preset reference value.

[0547] In this regard, the robot vacuum cleaner station (1100) according to the second embodiment of the present invention may further include a sensor (290).

[0548] The sensor (290) can measure the moisture content of the mop. The sensor (290) may be placed on the rotating plate (241) of the robot vacuum cleaner (200). In this case, the sensor (290) can transmit the moisture content information of the mop to the robot vacuum cleaner station (1100). As another example, the sensor (290) may be placed on the washing plate (122) of the robot vacuum cleaner station (1100). When the robot vacuum cleaner (200) is connected to the robot vacuum cleaner station (1100), the sensor (290) can measure the moisture content by contacting at least a portion of the mop. The sensor (290) can transmit the measured moisture content information to the control unit (300). The sensor (290) can measure the moisture content of the mop (242) while the drying of the mop (242) is in progress.

[0549] When the moisture content measured by the sensor (290) is below a preset threshold, the control unit (300) can operate the first flow path switching valve (1130d) to separate the mop drying unit (1170) from the outside air supply flow path (1171a) and connect the mop drying unit (1170) to the first circulation flow path (1130c). At this time, drying of the mop (242) is stopped and sterilization of the dust collection unit housing (1141) can begin.

[0550]

[0551] Meanwhile, the robot vacuum cleaner station (1100) according to the second embodiment of the present invention may further include a temperature sensor (141f).

[0552] The temperature sensor (141f) can measure the temperature inside the dust collection housing (1141). For example, the temperature sensor (141f) can be placed inside the dust collection housing (1141). The temperature sensor (141f) can transmit the measured temperature information to the control unit (300). The first flow path switching valve (1130d) can be operated by the control unit (300) when the temperature measured by the temperature sensor (141f) is above a preset reference value. For example, when the temperature inside the dust collection housing (1141) is 55°C or higher, the first flow path switching valve (1130d) can separate the mop drying unit (1170) from the first circulation flow path (1130c) and connect the mop drying unit (1170) to the outside air supply flow path (1171a). Through this, the flow of air discharged into the dust collection housing (1141) can be blocked. That is, sterilization of the dust collection housing (1141) can be stopped.

[0553]

[0554] Hereinafter, the operation process of the first Euro switching valve (1130d) in the robot vacuum cleaner station (1100) according to the second embodiment of the present invention will be described in detail.

[0555] First, with the robot vacuum cleaner (200) connected to the robot vacuum cleaner station (1100), the mop drying unit (1170) may be connected to the outside air supply path (1171a) and separated from the first circulation path (1130c). That is, the mop drying unit (1170) may be in communication with the receiving space (S) through the outside air supply path (1171a). Air heated by the mop drying unit (1170) may flow into the receiving space (S) along the outside air supply path (1171a). The air flowing into the receiving space (S) may dry the mop (242) of the robot vacuum cleaner.

[0556] When a preset time has elapsed since the drying of the mop (242) began, the control unit (300) can operate the first flow switching valve (1130d). For example, the first flow switching valve (1130d) can be set to operate when 10 minutes have elapsed since the drying of the mop (242) began. At this time, the first flow switching valve (1130d) can separate the mop drying unit (1170) from the outside air supply flow path (1171a) and connect the mop drying unit (1170) to the first circulation flow path (1130c). Accordingly, the mop drying unit (1170) can be connected to the dust collection unit housing (1141) through the first circulation flow path (1130c). Air heated by the rag drying unit (1170) can flow into the dust collection unit housing (1141) along the first circulation path (1130c). According to this configuration, sterilization of the dust collection unit housing (1141) can be performed.

[0557] As another example, if the moisture content of the rag (242) measured by the sensor (290) decreases below a preset threshold, the control unit (300) can operate the first flow switching valve (1130d). Accordingly, sterilization of the dust collection unit housing (1141) can be performed.

[0558] Meanwhile, when sterilization of the dust collection housing (1141) begins, the internal temperature of the dust collection housing (1141) rises. The temperature sensor (141f) can measure the internal temperature of the dust collection housing (1141).

[0559] For example, if the temperature measured by the temperature sensor (141f) is 55°C or higher, the first flow path switching valve (1130d) can connect the mop drying unit (1170) to the outside air supply flow path (1171a) and separate the mop drying unit (1170) from the first circulation flow path (1130c). Accordingly, sterilization of the dust collection unit housing (1141) can be stopped. On the other hand, if the temperature measured by the temperature sensor (141f) is less than 55°C, the mop drying unit (1170) can remain connected to the first circulation flow path (1130c).

[0560] As another example, if the temperature measured by the temperature sensor (141f) is 55°C or higher, the operation of the heater (1171d) may be terminated. Accordingly, the sterilization of the dust collection housing (1141) may be stopped. On the other hand, if the temperature measured by the temperature sensor (141f) is less than 55°C, the operation of the heater (1171d) may continue.

[0561]

[0562] Third embodiment

[0563]

[0564] FIG. 30a is a drawing for explaining the external air supply path and the air discharge path in a robot vacuum cleaner station according to a third embodiment of the present invention. FIG. 30b is a drawing for explaining the first circulation path and the second circulation path in a robot vacuum cleaner station according to a third embodiment of the present invention.

[0565] With reference to FIGS. 30a and FIGS. 30b, a robot vacuum cleaner station (2100) according to a third embodiment of the present invention will be described.

[0566] To avoid repetitive explanations, the robot vacuum cleaner station according to the second embodiment of the present invention has the same configuration and effect as the one described in this embodiment, except for configurations not specifically described therein, so it may be adapted.

[0567]

[0568] The dust collection housing (2141) of the robot vacuum cleaner station (2100) according to the third embodiment of the present invention may further include a hot air discharge port (2141e). That is, the dust collection housing (2141) may include a hot air inlet (2141d) and a hot air discharge port (2141e).

[0569] A hot air inlet (2141d) may be formed on the lower rear side of the dust collector housing (2141). The hot air inlet (2141d) may be connected to the first circulation path (2130c). Air may pass through the first circulation path (2130c) and flow into the dust collector housing (2141) through the hot air inlet (2141d).

[0570] A hot air discharge port (2141e) may be formed on the upper rear side of the dust collection housing (2141). Air introduced from the hot air inlet (2141d) may be discharged through the hot air discharge port (2141e). The hot air discharge port (2141e) may be connected to a second circulation path (2172e) to be described later. Air discharged through the hot air discharge port (2141e) may flow through the second circulation path (2172e) to the air discharge section (2172).

[0571] For example, on the rear side of the dust collector housing (2141), the hot air inlet (2141d) may be positioned at the lower left and the hot air outlet (2141e) may be positioned at the upper right. On the rear side of the dust collector housing (2141), the hot air inlet (2141d) and the hot air outlet (2141e) may be positioned diagonally. With this configuration, air introduced into the dust collector housing (2141) can circulate inside along a path extended to the left and right, and then be discharged to the outside of the dust collector housing (2141).

[0572]

[0573] Meanwhile, the air discharge section (2172) of the robot vacuum cleaner station (2100) according to the third embodiment of the present invention may include an air discharge path (2172c), a second circulation path (2172e), and a second path switching valve (2172f).

[0574] The air exhaust passage (2172c) can exhaust air from within the receiving space (S) to the outside. At this time, one end of the air exhaust passage (2172c) can be connected to the receiving space (S), and the other end can be connected to the drain pipe (25). Specifically, the air intake (172a), which is one end of the air exhaust passage (2172c), can be connected to the receiving space (S), and the air exhaust (172b), which is the other end, can be connected to the drain pipe (25).

[0575] The second circulation path (2172e) can connect the dust collector housing (2141) and the air discharge section (2172). That is, one end of the second circulation path (2172e) is connected to the dust collector housing (2141) through the hot air discharge port (2141e), and the other end can be connected to the air discharge section (2172). Air inside the dust collector housing (2141) can flow to the air discharge section (2172) through the second circulation path (2172e). The air flowing to the air discharge section (2172) can join with the air discharge path (2172c) and be discharged to the outside. That is, the second circulation path (2172e) can discharge air inside the dust collector housing (2141) to the outside.

[0576] The second flow switching valve (2172f) may be positioned between the air discharge section (2172) and the second circulation flow path (2172e). The second flow switching valve (2172f) may open and close the second circulation flow path (2172e) connected to the air discharge section (2172).

[0577] First, the second Euro switching valve (2172f) is described in a state where it is connected to the second circulation path (2172e) and the air discharge section (2172). At this time, the air circulating inside the dust collection housing (2141) can be discharged to the outside through the second circulation path (2172e).

[0578] Meanwhile, the second Euro switching valve (2172f) can separate the second circulation path (2172e) from the air discharge section (2172). At this time, the flow of air moving from the dust collection housing (2141) to the air discharge section (2172) can be stopped.

[0579]

[0580] Meanwhile, the robot vacuum cleaner station (2100) according to the third embodiment of the present invention may include a dust bag drawer (144) and a dust bag (not shown).

[0581] The dust bag drawer (144) can be pulled out and coupled to the front of the dust collection housing (2141). The dust bag drawer (144) can accommodate a dust bag (not shown) inside. Air heated by the mop drying unit (2170) can be introduced into the interior of the dust bag drawer (144) through the first circulation path (2130c). After circulating the interior space of the dust bag drawer (144) containing the dust bag (not shown), the air can be discharged to the air discharge unit (2172) through the second circulation path (2172e). Through this, the dust bag (not shown) can be sterilized.

[0582] Meanwhile, the conditions for ending the drying of the rag (242) are explained in detail.

[0583] For example, the first flow switching valve (2130d) and the second flow switching valve (2172f) can be operated by the control unit (300) after a preset time has elapsed since the drying of the mop (242) began. Specifically, the first flow switching valve (2130d) and the second flow switching valve (2172f) can be operated by the control unit (300) after 10 minutes have elapsed since the drying of the mop (242) began. At this time, the drying of the mop (242) is stopped, and the sterilization of the dust collection unit housing (2141) can begin.

[0584]

[0585] As another example, the first Euro switching valve (2130d) and the second Euro switching valve (2172f) can be operated by the control unit (300) when the moisture content measured by the sensor (290) is below a preset reference value.

[0586] In this regard, the robot vacuum cleaner station (2100) according to the third embodiment of the present invention may further include a sensor (290).

[0587] Specifically, the sensor (290) can transmit the measured moisture content information to the control unit (300). If the moisture content measured by the sensor (290) is below a preset threshold, the control unit (300) can operate the first flow path switching valve (2130d) to connect the mop drying unit (2170) and the first circulation flow path (2130c). Additionally, under the same conditions, the control unit (300) can operate the second flow path switching valve (2172f) to connect the air discharge unit (2172) and the second circulation flow path (2172e). Accordingly, the drying of the mop (242) is stopped, and the sterilization of the dust collection unit housing (2141) can begin.

[0588]

[0589] According to the third embodiment of the present invention, the process of operating the first flow switching valve (2130d) and the second flow switching valve (2172f) is described in detail.

[0590] When drying of the mop (242) begins, the moisture content of the mop (242) decreases, and the sensor (290) can measure the moisture content of the mop (242). The sensor (290) can transmit the moisture content information to the robot vacuum cleaner station (2100). The sensor (290) can transmit the measured moisture content information to the control unit (300). The control unit (300) can control the operation of the first flow path switching valve (2130d) and the second flow path switching valve (2172f) based on the received information.

[0591] When the moisture content of the mop (242) decreases to 1% or less, the control unit (300) can operate the first flow switching valve and the second flow switching valve (2172f). The first flow switching valve (2130d) can connect the dust collection unit sterilization module (2130) and the first circulation flow path (2130c). At the same time, the second flow switching valve (2172f) can connect the air discharge unit (2172) and the second circulation flow path (2172e). Accordingly, the dust collection unit sterilization module (2130) can be in communication with the dust collection unit housing (2141) through the first circulation flow path (2130c), and the dust collection unit housing (2141) can be in communication with the air discharge unit (2172) through the second circulation flow path (2172e). Air heated by the dust collection unit sterilization module (2130) can flow into the dust collection unit housing (2141) along the first circulation path (2130c). Air circulating inside the dust collection unit housing (2141) can flow into the air discharge unit (2172) along the second circulation path (2172e). According to this configuration, sterilization of the dust collection unit housing (2141) can be performed.

[0592]

[0593] The first flow switching valve (2130d) and the second flow switching valve (2172f) can be operated by the control unit (300) after a preset time has elapsed since the sterilization of the dust collection unit housing (2141) began. For example, when 10 minutes have elapsed since the first flow switching valve (2130d) and the second flow switching valve (2172f) were operated, the control unit (300) can operate the first flow switching valve (2130d) and the second flow switching valve (2172f) again. At this time, the first flow switching valve (2130d) can separate the dust collection unit sterilization module (2130) from the first circulation flow path (2130c) and connect the dust collection unit sterilization module (2130) to the outside air supply flow path (2171a). The second Euro switching valve (2172f) can separate the air discharge section (2172) and the second circulation path (2172e). Accordingly, sterilization of the dust collection housing (2141) can be stopped.

[0594]

[0595] As another example, the robot vacuum cleaner station (2100) according to the third embodiment of the present invention may further include a temperature sensor (141f).

[0596] The first flow switching valve (2130d) and the second flow switching valve (2172f) can be operated by the control unit (300) when the temperature of the dust collection unit housing (2141) measured by the temperature sensor (141f) is above a preset reference value. At this time, the first flow switching valve (2130d) can separate the dust collection unit sterilization module (2130) from the first circulation flow path (2130c) and connect the dust collection unit sterilization module (2130) to the outside air supply flow path (2171a). Under the same conditions, the second flow switching valve (2172f) can separate the air discharge unit (2172) from the second circulation flow path (2172e). Accordingly, the sterilization of the dust collection unit housing (2141) can be stopped.

[0597]

[0598] 4th embodiment

[0599]

[0600] FIG. 31 is a drawing for explaining a dust collection unit sterilization module in a robot vacuum cleaner station according to the fourth embodiment of the present invention.

[0601] Referring to FIG. 31, the dust collection unit sterilization module (3130) of the robot vacuum cleaner station (3100) according to the fourth embodiment of the present invention is described as follows.

[0602]

[0603] Meanwhile, except for the configuration not specifically described in this embodiment of the robot vacuum cleaner station (3100) according to the fourth embodiment of the present invention, the configuration and effects are identical to those of the robot vacuum cleaner station according to one embodiment of the present invention, so the same may be utilized.

[0604] More specifically, the dust collection unit sterilization module (3130) according to the fourth embodiment may include a light source (not shown). Additionally, the dust collection unit housing (3141) may include a dust bag (3143), a dust bag drawer (144), and a transparent panel (3143a).

[0605] On the other hand, the dust collection unit sterilization module (3130) may not include a circulation fan and a heater. Additionally, the dust collection unit housing (3141) may not include a hot air inlet, a hot air outlet, and a temperature sensor.

[0606]

[0607] A light source (not shown) can emit sterilization light. The light source (not shown) may be a UV-C LED. The light source (not shown) may be positioned at the rear upper side inside the dust collection housing (3141). The light source (not shown) may emit sterilization light from the rear upper side of the dust collection housing (3141) toward the inside of the dust collection housing (3141). Through this, the inside of the dust collection housing (3141) can be sterilized.

[0608] More specifically, the dust collection housing (3141) is coupled to allow a dust bag drawer (144) to be pulled out inside, and a dust bag (3143) can be stored inside the dust bag drawer (144). That is, the dust collection housing (3141) can accommodate a dust bag (3143) inside. The dust bag (3143) can collect dust introduced from the robot vacuum cleaner (200). A transparent panel (3143a) can be formed to transmit the sterilization light into the dust bag (3143). The transparent panel (3143a) can be placed on the upper side of the dust bag (3143). With the dust bag (3143) accommodated inside the dust collection housing (3141), the transparent panel (3143a) can be placed in a position facing the light source (not shown). Accordingly, the sterilizing light from the light source (not shown) can pass through the transparent panel (3143a) and be emitted into the dust bag (3143). Through this, the inside of the dust bag (3143) can be sterilized.

[0609]

[0610] Control method

[0611]

[0612] Meanwhile, FIG. 32 is a block diagram illustrating the control configuration in a robot vacuum cleaner station according to a second embodiment of the present invention. FIG. 33 is a block diagram illustrating the control configuration in a robot vacuum cleaner station according to a third embodiment of the present invention. FIG. 34 is a flowchart illustrating a robot vacuum cleaner control method according to a second embodiment of the present invention.

[0613] A control method for a robot vacuum cleaner station according to a second embodiment of the present invention may include a mop drying step (S10), a flow path switching step (S20), and a dust collection unit sterilization step (S30).

[0614] The mop drying step (S10) can dry the mop (242) of the robot vacuum cleaner (200) by discharging hot air into the receiving space (S). Specifically, when the control unit (300) receives a signal that the washing of the mop (242) has ended, it can operate the heater (1171d) and the circulation fan (1173) of the mop drying unit (1170). Air heated by the heater (1171d) can be discharged into the receiving space (S) by the circulation fan (1173). Accordingly, the drying of the mop (242) of the robot vacuum cleaner (200) can be achieved.

[0615] At the same time, the sensor (290) can measure the moisture content of the rag (242). The measured moisture content information can be transmitted to the control unit (300).

[0616]

[0617] Accordingly, in the rag drying step (S10), the control unit (300) can determine whether to end the drying of the rag (242) based on the moisture content measured through the sensor (290).

[0618] More specifically, the moisture content of the mop (242) is measured during the mop drying step (S10). The control unit (300) can receive moisture content information from the sensor (290). If the measured moisture content is less than a preset threshold, the control unit (300) can proceed to the next step. For example, if the received moisture content is less than 1%, the control unit (300) can proceed to the next step.

[0619] Conversely, if the measured moisture content is greater than or equal to a preset threshold, the control unit (300) can continue to perform the rag drying step (S10).

[0620]

[0621] In the flow switching step (S20), the control unit (300) can operate the first flow switching valve (1130d). At this time, the first flow switching valve (1130d) can separate the mop drying unit (1170) from the outside air supply flow path (1171a) and connect the mop drying unit (1170) to the first circulation flow path (1130c). Accordingly, the flow of air flowing into the receiving space (S) is stopped, and the drying of the mop (242) can be terminated. Meanwhile, in the flow switching step (S20), the control unit (300) can maintain the operation of the heater (1171d) and the circulation fan (1173). In this case, while the air flow continues, the first flow switching valve (1130d) can operate to change the air flow.

[0622] As another example, the control unit (300) can first stop the operation of the heater (1171d) and the circulation fan (1173), and then operate the first flow path switching valve (1130d) to separate the mop drying unit (1170) from the outside air supply flow path (1171a). Afterward, the control unit (300) can resume the operation of the heater (1171d) and the circulation fan (1173) when the mop drying unit (1170) and the first circulation flow path (1130c) are connected.

[0623]

[0624] In the dust collection unit sterilization step (S30), hot air can be discharged into the dust collection unit housing (1171) to sterilize the interior. More specifically, in the dust collection unit sterilization step (S30), the mop drying unit (1170) and the first circulation path (1130c) may be connected. Air heated by the heater (1171d) can be discharged into the dust collection unit housing (1171) along the first circulation path (1130c). Accordingly, sterilization of the interior of the dust collection unit housing (1171) can be achieved. Additionally, the internal temperature of the dust collection unit housing (1171) may rise.

[0625]

[0626] In the dust collection unit sterilization step (S30), the sterilization of the dust collection unit housing (1171) can be terminated depending on the conditions.

[0627] For example, when the control unit (300) receives a signal that the internal temperature of the dust collection unit housing (1171) measured by the temperature sensor (141f) is above a reference value, it may operate the first flow path switching valve (1130d) to block the discharge of air to the dust collection unit housing (1171). Alternatively, the control unit (300) may stop the operation of the heater (1171d) under the same conditions to terminate the sterilization of the dust collection unit housing (1171).

[0628] As another example, after a certain amount of time has elapsed since the start of the Euro switching step (S20), the control unit (300) may operate the first Euro switching valve (1130d) to block the discharge of air to the dust collection housing (1171). Alternatively, the control unit (300) may stop the operation of the heater (1171d) under the same conditions to terminate the sterilization of the dust collection housing (1171).

[0629] In the dust collection unit sterilization step (S30), the control unit (300) can maintain the operation of the heater (1171d) and the circulation fan (1173). In this case, while the air flow continues, the first flow path switching valve (1130d) can operate to change the air flow.

[0630] As another example, the control unit (300) can first stop the operation of the heater (1171d) and the circulation fan (1173), and then operate the first flow path switching valve (1130d) to separate the mop drying unit (1170) from the first circulation path (1130c). Afterward, the control unit (300) can resume the operation of the heater (1171d) and the circulation fan (1173) when the mop drying unit (1170) and the outside air supply path (1171a) are connected.

[0631]

[0632] A control method for a robot vacuum cleaner station according to a third embodiment of the present invention will be described. The control method for a robot vacuum cleaner station may include a mop drying step (S10), a flow path switching step (S20), and a dust collection unit sterilization step (S30).

[0633] To avoid repetitive explanations, the robot vacuum cleaner station control method and content according to the second embodiment of the present invention are identical except for configurations not specifically described in this embodiment, so the same may be used.

[0634]

[0635] In the Euro switching step (S20), the control unit (300) can operate the first Euro switching valve (2130d) and the second Euro switching valve (2172f).

[0636] At this time, the first flow switching valve (2130d) can separate the mop drying section (2170) from the outside air supply flow path (2171a) and connect the mop drying section (2170) to the first circulation flow path (2130c). Additionally, the second flow switching valve (2172f) can connect the air discharge section (2172) to the second circulation flow path (2172e). Accordingly, the flow of air flowing into the receiving space (S) is stopped, and the drying of the mop (242) can be terminated.

[0637]

[0638] In the dust collection unit sterilization step (S30), hot air can be discharged into the dust collection unit housing (2141) to sterilize the interior. More specifically, in the dust collection unit sterilization step (S30), the mop drying unit (2170) and the first circulation path (2130c) may be connected, and the air discharge unit (2172) and the second circulation path (2172e) may be connected. Air heated by the heater (2171d) can be discharged into the dust collection unit housing (2141) along the first circulation path (2130c). Air circulating inside the dust collection unit housing (2141) can flow to the air discharge unit (2172) along the second circulation path (2172e). Accordingly, sterilization of the interior of the dust collection unit housing (2141) can be achieved.

[0639]

[0640] In the dust collection unit sterilization step (S30), the sterilization of the dust collection unit housing (2141) can be terminated depending on the conditions.

[0641] For example, when the control unit (300) receives a signal that the internal temperature of the dust collection unit housing (2141) measured by the temperature sensor (141f) is above a reference value, it may operate the first flow path switching valve (2130d) to block the discharge of air to the dust collection unit housing (2141) and operate the second flow path switching valve (2172f) to separate the air discharge unit (2172) and the second circulation flow path (2172e). Alternatively, the control unit (300) may stop the operation of the heater (2171d) under the same conditions to terminate the sterilization of the dust collection unit housing (2141).

[0642] As another example, after a certain amount of time has elapsed since the start of the Euro switching step (S20), the control unit (300) may operate the first Euro switching valve (2130d) to block the discharge of air to the dust collection unit housing (2141) and may operate the second Euro switching valve (2172f) to separate the air discharge unit (2172) and the second circulation path (2172e). Alternatively, the control unit (300) may stop the operation of the heater (2171d) under the same conditions to terminate the sterilization of the dust collection unit housing (2141).
