Description

Technical Field

[0001] This invention relates to a robot vacuum cleaner base station, and more specifically, to a built-in robot vacuum cleaner base station that, when integrated with a robot vacuum cleaner, can collect dust from the robot vacuum cleaner's dustbin and clean and dry the robot vacuum cleaner's mop, as well as a control method for the robot vacuum cleaner base station. Background Technology

[0002] In recent years, with the development of industrial technology, sweeping robots have been developed that can autonomously drive and clean areas that need to be cleaned without user intervention.

[0003] This robotic vacuum cleaner includes sensors that can identify the space to be cleaned, an agitator that can clean the floor surface, and a cloth that can wipe the floor surface. It can suck up dust from the floor surface of the space identified by the sensors, wipe it with the cloth, and then move around.

[0004] Robotic vacuum cleaners include dry-type vacuum cleaners that can suck up and remove debris scattered on the floor, and wet-type vacuum cleaners that can wipe the floor with a damp cloth to effectively remove debris adhering to the floor. Dry-type vacuum cleaners have a dustbin and use a suction motor to suck up debris from the floor. Wet-type vacuum cleaners have a water tank; water in the tank is supplied to a damp cloth, which wipes the floor to effectively remove debris. Additionally, there are also robotic vacuum cleaners that include an agitator and a cloth.

[0005] A charging station for a robotic vacuum cleaner is a device that allows the robot to dock after cleaning and charges its battery by supplying power to the robot's internal battery. The charging station contains a power supply module. It has charging terminals that connect to the power supply module, and the robotic vacuum cleaner has corresponding terminals. When the charging terminals and corresponding terminals are in contact, power is supplied to the battery, and the battery is charged.

[0006] On the other hand, when a robot vacuum charging station is installed indoors, it occupies a fixed area of ​​indoor space. In this case, it may reduce the space efficiency of the room. Additionally, collisions with the robot vacuum may occur as users or pets pass by, potentially causing injury to the user or pet, and damage to the robot vacuum.

[0007] In addition, in the case of base stations equipped with dust collection functions of robotic vacuum cleaners, there is a limitation that as the volume they occupy increases, they may damage the interior decoration.

[0008] On the other hand, Chinese utility model patent CN218922468U discloses a base station for a cleaning machine that integrates a sweeping robot on the lower side of a washing machine, and is used to charge the sweeping robot, collect dust, and clean the wet cloth of the sweeping robot.

[0009] The vacuum cleaner base station is configured to dry the cloth disposed on the upper side of the cleaning tank by supplying dry air to the cleaning tank of the cleaning robot's cloth.

[0010] However, as with the aforementioned vacuum cleaner base station, drying cloths in an open indoor space presents limitations such as the possibility of increased indoor humidity due to water vapor generated during the drying process, and the potential for wastewater from washing cloths to spread into the room due to odors during drying.

[0011] In addition, the heated air diffuses outward during the drying of cloths in an open space, and a continuous supply of heated air is required for a long time, which limits the energy efficiency.

[0012] In addition, in the case of base stations that use steam to dry cloths, if the moisture and contaminants inside the cloths are not removed in time after washing, foul odors and hygiene problems may occur. Summary of the Invention

[0013] The present invention is proposed to improve the problems existing in the existing robot vacuum base stations as described above, and its purpose is to provide a robot vacuum base station that can be embedded in the lower side of a kitchen cabinet without the need for additional installation space.

[0014] In addition, the purpose is to provide a robot vacuum station that can accommodate a robot vacuum in the lower space of a kitchen cabinet with a specified height limit.

[0015] In addition, the purpose is to provide a robot vacuum station that, when combined with a robot vacuum, can automatically collect dust from the robot vacuum's dustbin.

[0016] In addition, the purpose is to provide a robot vacuum cleaner base station and a control method for properly regulating the internal humidity to solve hygiene problems that may arise during the cleaning and drying of the cleaning cloth.

[0017] To achieve the objectives described above, the robotic vacuum cleaner base station of the present invention may include: a cover, including an upper side cover; a base, housed inside the cover and disposed on the lower side of the robotic vacuum cleaner; a receiving space formed between the base and the upper side cover, for accommodating the robotic vacuum cleaner; a mop cleaning section for cleaning the mop of the robotic vacuum cleaner; and a mop drying section for drying the mop by expelling air into the mop; the mop cleaning section may include a steam supply section that supplies hot water or wet steam to the receiving space by heating water; the mop drying section may include a blower fan that provides airflow to expel the air into the receiving space; the blower fan is capable of operating during the operation of the steam supply section.

[0018] On the other hand, it may include an air exhaust section for discharging air from the containment space; the air exhaust section may include: an air intake in communication with the containment space to draw in air; and an exhaust fan for providing flow force to the air drawn in through the air intake; the exhaust fan is capable of operating during the operation of the steam supply section.

[0019] Additionally, the air supply fan can be configured in the housing with the air exhaust side facing the receiving space; the exhaust fan can be configured with the air intake side facing the receiving space.

[0020] On the other hand, the enclosure may include a door for opening and closing the entrance and exit of the sweeping robot; the door can be opened during the operation of the steam supply unit.

[0021] Additionally, a humidity sensor may be included to measure the humidity inside the enclosure; if the humidity measured by the humidity sensor is above a predetermined reference value, the exhaust fan may operate.

[0022] On the other hand, it may also include a humidity sensor for measuring the humidity inside the enclosure; if the humidity measured by the humidity sensor is above a predetermined reference value, the air supply fan may operate.

[0023] Alternatively, it may include a humidity sensor for measuring the humidity inside the enclosure; if the humidity measured by the humidity sensor is above a predetermined reference value, the door may be opened.

[0024] The control method of the sweeping robot base station of the present invention may include: a cleaning step of washing the mop by supplying washing water to the mop of the sweeping robot when the sweeping robot is attached to the sweeping robot base station; a sterilization cleaning step of sterilizing the mop by expelling heated water or wet steam to the mop; and a mop drying step of drying the mop by operating a blower fan that expels air to the mop; wherein the blower fan may be operated in the sterilization cleaning step.

[0025] In addition, during the sterilization and cleaning step, the water can be heated to a temperature above 55 degrees Celsius but below 70 degrees Celsius.

[0026] On the other hand, in the sterilization and cleaning step, the water can be heated to above 100 degrees Celsius.

[0027] In addition, during the sterilization and cleaning step, an exhaust fan can be operated to expel air from inside the robot vacuum cleaner base station.

[0028] Additionally, if the humidity inside the robotic vacuum cleaner base station is above a specified baseline value, air can be allowed to flow in.

[0029] On the other hand, if the humidity inside the robot vacuum cleaner base station is above a specified baseline value, the door of the robot vacuum cleaner base station can be opened.

[0030] On the other hand, if the humidity inside the robot vacuum cleaner base station is above a specified baseline value, the air supply fan can be operated.

[0031] Additionally, if the humidity inside the robotic vacuum cleaner base station is lower than a specified baseline value, airflow can be interrupted.

[0032] On the other hand, if the humidity inside the robot vacuum cleaner base station is lower than a specified baseline value, the door can be closed.

[0033] Additionally, the operation of the air blower can be interrupted once the cloth drying step is completed.

[0034] On the other hand, the operation of the exhaust fan can be interrupted once the cloth drying step is completed.

[0035] As described above, the robot vacuum base station according to the present invention can be configured in a direction horizontal to the robot vacuum, and can charge the robot vacuum, collect dust, and clean the mop, thereby having the effect of utilizing the space under the kitchen cabinet.

[0036] In addition, the robot vacuum cleaner is surrounded by a charging terminal, a dust collection unit, a mop washing unit, and a mop drying unit, thus enabling it to perform various functions of the robot vacuum cleaner simultaneously.

[0037] In addition, the other sides are covered by kitchen cabinets, thus providing aesthetic appeal to users in terms of decoration.

[0038] In addition, it can prevent internal humidity from rising even during water- or steam-based cloth washing operations and improve the efficiency of the drying process. Attached Figure Description

[0082] Furthermore, the following embodiments are provided to enable those skilled in the art to understand more fully, and for the purpose of clearer illustration, the shape and size of the structural elements in the drawings may be exaggerated.

[0083] Kitchen cabinets and sweeping systems

[0084] Figure 1 A diagram is shown illustrating the state in which the cleaning system of an embodiment of the present invention is installed on the underside of a kitchen cabinet. Figure 2 A diagram illustrating the piping and drainage pipe connections of the sweeper system according to an embodiment of the present invention is shown.

[0085] Reference Figure 1 and Figure 2 The cleaning system 1 of this embodiment can be installed on the lower side of the kitchen cabinet 2. Specifically, the kitchen cabinet 2 can be installed in the kitchen to store bowls, plates, cups, etc., and can provide space for cooking food or washing dishes.

[0086] In addition, kitchen cabinet 2 can be equipped with an upper panel (workbench) that can function as a sink, cooking table, or work surface.

[0087] For example, kitchen cabinet 2 may include a sink that provides space for washing dishes on the upper shelf. Alternatively, kitchen cabinet 2 may include a cooking countertop for performing cooking operations. Additionally, kitchen cabinet 2 may include a gas stovetop with a gas cooktop, induction cooker, pressure cooker, or oven mounted on the upper shelf.

[0088] Typically, kitchen cabinet 2 can use a standard cabinet with a front-to-back width of 600mm and a left-to-right width of 600mm.

[0089] In another embodiment of the present invention, the sweeper system 1 can be disposed on the underside of a structure including at least one of a water supply pipe and a drain pipe. Specifically, the water supply pipe can refer to a flow path connected to an external water source that supplies fluid to the structure, and the drain pipe can refer to a flow path that discharges fluid from the structure into a sewer.

[0090] A storage cabinet for storing tableware and kitchen utensils can be installed at the lower part of this kitchen cabinet 2 or the structure described above. That is, the kitchen cabinet 2 or the structure described above may include: an upper panel 22 providing space for cooking or washing dishes; a lower side panel 23 separated from the ground at a predetermined height; and storage space formed between the upper panel 22 and the lower side panel 23 for storing tableware and kitchen utensils. In the case where the kitchen cabinet 2 is a sink, a sink 22a can be installed on the upper panel 22.

[0091] Additionally, the lower side panel 23 can be supported by legs 21. Legs 21 can be configured perpendicular to the bottom of the kitchen to support the load of the kitchen cabinet 2. In this case, a space can be formed between the kitchen floor and the lower side panel 23 along the height of the legs 21.

[0092] In contrast, the kitchen cabinet 2 can also be fixed to the wall of the building without the support legs 21. In this case, a space can also be formed between the kitchen floor and the lower side panel 23.

[0093] The cleaning system 1 of this invention can be installed in the space between the floor and the lower side panel 23 of a kitchen as described above (hereinafter referred to as the installation space).

[0094] For example, the installation space can be less than 200mm in height, and typically can be less than 160mm in height.

[0095] Therefore, according to the present invention, the cleaning system 1 is disposed in the lower space of the kitchen cabinet 2, thus having the effect of minimizing the amount of the cleaning system 1 exposed to the outside.

[0096] Furthermore, compared to configuring a charging station for a robot vacuum cleaner in a constant space such as the living room, bedroom, or kitchen, configuring the cleaning system 1 in the unused space created by the kitchen cabinet 2 does not occupy additional space, thus maximizing space efficiency.

[0097] On the other hand, a drain pipe 25 is provided in the kitchen cabinet 2 or the structure to drain liquids used for cooking or water used for washing dishes. At least a portion of the drain pipe 25 can be configured in the storage space formed between the upper panel 22 and the lower side panel 23. Typically, the drain pipe 25 can be connected to the drain outlet of the sink 22a formed in the sink. The drain pipe 25 includes a U-trap 25a to prevent backflow of contaminated gases or odors. The U-trap 25a can be configured in the storage space. Liquid flowing in through the drain outlet flows downward by gravity in the upstream 25b of the U-trap and accumulates in the U-trap 25a. If the water overflows above a predetermined water level set by the U-trap 25a, it can flow downward along the downstream 25c of the U-trap and be discharged into the sewer.

[0098] The vacuum cleaner system 1 of this embodiment can use the drain pipe 25 as described above to clean and dry the mop 242 of the sweeping robot 200.

[0099] Additionally, although not shown in the diagram, a water supply pipe may be installed in the kitchen cabinet 2. Tap water (or purified water) can be supplied to the cleaning system 1 through the water supply pipe.

[0100] The specific structure of the vacuum cleaner system 1 will be described below.

[0101] Vacuum Cleaner System

[0102] on the other hand, Figure 3 A perspective view of a vacuum cleaner system for illustrating an embodiment of the present invention is shown. Figure 4 It shows Figure 3 Top view.

[0103] The cleaning system 1 in the embodiments of this specification may include a sweeping robot base station 100 and a sweeping robot 200.

[0104] The cleaning system 1 includes a robot vacuum base station 100. A robot vacuum 200 can be integrated into the robot vacuum base station 100. Specifically, the robot vacuum 200 can enter from the front of the robot vacuum base station 100 and can be housed inside the robot vacuum base station 100. The robot vacuum base station 100 can remove dust from the dustbin 220 of the robot vacuum 200. The robot vacuum base station 100 can clean the rotating cleaning section 240 of the robot vacuum 200. The robot vacuum base station 100 can dry the rotating cleaning section 240 of the robot vacuum 200. The robot vacuum base station 100 can supply power to the robot vacuum 200.

[0105] robot vacuum

[0106] on the other hand, Figures 5 to 8A diagram illustrating a sweeping robot system according to an embodiment of the present invention is provided.

[0107] Reference Figures 5 to 8 The structure of the 200 robotic vacuum cleaner is as follows.

[0108] The robotic vacuum cleaner 200 autonomously navigates the area to be cleaned and sucks up dust and other foreign objects from the floor, thus automatically cleaning the area.

[0109] The robotic vacuum cleaner 200 of this embodiment is placed on the floor and moves along the floor surface to clean the floor. Therefore, the following description will be based on the state of the robotic vacuum cleaner 200 placed on the floor, defining the vertical direction.

[0110] Furthermore, taking a pair of wheels 260 as a reference, the side with the auxiliary wheel 270 (described later) is designated as the front, and the side with the rotating cleaning unit 240 (described later) is designated as the rear, and will be described.

[0111] The “lowest part” of each component described in the embodiments of the present invention may be the part located at the lowest position in each component when the robot vacuum cleaner 200 of the present invention is placed on the floor for use, or it may be the part closest to the floor.

[0112] The sweeping robot 200 of this invention includes a main body 210, a dust bin 220, a water bin 230, a rotating sweeping part 240, an agitator 250, wheels 260, auxiliary wheels 270, and a charging terminal 280.

[0113] The main body 210 can form the overall shape of the robotic vacuum cleaner 200. Various components that make up the robotic vacuum cleaner 200 can be integrated into the main body 210, and some of the components that make up the robotic vacuum cleaner 200 can be housed inside the main body 210.

[0114] Specifically, the main body 210 may house a plurality of components of the robotic vacuum cleaner 200 within its internal space. For example, the main body 210 may house a battery and at least one motor within its internal space.

[0115] In embodiments of the present invention, the main body 210 may be configured such that its width (or diameter) in the horizontal direction is greater than its height in the vertical direction. This main body 210 helps the robotic vacuum cleaner 200 to form a stable structure and provides a structure that facilitates the robotic vacuum cleaner 200 in avoiding obstacles during movement (driving).

[0116] When viewed from above or below, the main body 210 can be formed into various shapes such as circles, ovals, or quadrilaterals.

[0117] The main body 210 can be divided into a lower main body and an upper main body, which can be combined to form a space inside.

[0118] The lower main body can be combined with the upper main body to form an internal space that can accommodate a battery, at least one sensor, and at least one motor.

[0119] The lower body may have an intake section 211 for air to flow in and a hole for accommodating a pair of wheels 260.

[0120] The suction section 211 can be a channel for dust from the floor to flow into. Furthermore, the suction section 211 can communicate with a suction flow path (not shown) formed inside the main body 210, and the suction flow path can communicate with the internal space of the dust bin 220.

[0121] On the other hand, an exhaust flow path can also be provided in the lower main body. One side of the exhaust flow path can communicate with the internal space of the dust bin 220, and the other side can communicate with the exhaust port. At this time, a filter can be installed at the exhaust port.

[0122] With this configuration, the air flowing in through the suction section 211 can flow into the dust bin 220 via the suction flow path and be discharged to the exhaust port via the exhaust flow path.

[0123] The suction section 211 can accommodate a rotatable agitator 250, which will be described later. With this configuration, dust around the suction section 211 can be guided into the suction section 211 by the rotation of the agitator 250, thereby increasing the efficiency of dust suction.

[0124] The upper body can form the upper appearance of the robotic vacuum cleaner 200. Although not shown, a display can be installed on the upper body.

[0125] The robotic vacuum cleaner 200 of the present invention may include a bumper. The bumper is attached to the edge of the main body 210 and is movable relative to the main body 210.

[0126] The bumper can be attached to a portion of the edge of the body 210, or to the entire edge of the body 210. At least one elastic member (not shown) can be provided between the bumper and the body 210. With this configuration, if the bumper comes into contact with an obstacle or the like and moves relative to the center of the body 210, the bumper can be reset to its initial position by the restoring force of the elastic member (not shown), absorbing or dispersing the impact applied to the bumper, thereby preventing and reducing the transmission of impact to the body 210.

[0127] The dust bin 220 can suck in external dust and air to store dust.

[0128] The dust bin 220 can store dust that flows in through the suction flow path. The dust bin 220 can have a dust inlet communicating with the suction flow path, an internal space for storing dust, and an air outlet for discharging air.

[0129] The dust bin 220 can be disposed inside the main body 210. In this case, the dust bin 220 can be fixedly attached to the main body 210, but it can also be separated according to the embodiment.

[0130] On the other hand, in this invention, a dust discharge path can be formed in the dust bin 220. This dust discharge path allows the internal space of the dust bin 220 to communicate with the external space of the robotic vacuum cleaner 200. With this configuration, when dust is collected by the robotic vacuum cleaner base station 100, the dust inside the dust bin 220 can be removed.

[0131] On the other hand, the dust bin 220 of this embodiment of the invention may have a dust outlet 221 communicating with the dust discharge flow path. As one example, the dust outlet 221 may be formed on the rear side of the outer side (or outer peripheral surface) of the main body 210. As another example, the dust outlet 221 may be formed on the outer side of the dust bin 220.

[0132] Furthermore, the robotic vacuum cleaner 200 of this embodiment may be equipped with a dust bin door 222 capable of selectively opening and closing the dust outlet 221. Specifically, the dust bin door 222 may be attached to the main body 210 and may be configured in a position capable of blocking the dust outlet 221. As an example, the dust bin door 222 is formed of rubber or resin material, is rotatable, and one side may be fixedly attached to the main body 210.

[0133] With this configuration, if the dust collection motor 145 of the robotic vacuum cleaner base station 100 described later is operated, the dust bin door 222 can be elastically deformed by the driving force of the dust collection motor 145, and the dust discharge port 221 will open, so that the dust in the dust bin 220 can be collected into the dust collection section 140 of the robotic vacuum cleaner base station 100.

[0134] The bucket 230 is shaped as a container with an internal space to store liquids such as water inside. The bucket 230 can be disposed inside the main body 210, can be fixedly attached to the main body 210, or can be attached to the main body 210 in a way that allows for disassembly.

[0135] The water tank 230 includes a supply section 231 and a nozzle (not shown). The supply section 231 can receive liquids such as water from the outside. For example, the supply section 231 may have an inlet formed on the other side behind the outer side (or outer peripheral surface) of the main body 210, and can be connected to the storage space inside the water tank 230 via a water supply hose.

[0136] At this time, the supply unit 231 can be configured on the opposite side of the sweeping robot 200 in the left-right direction in relation to the dust discharge port 221. For example, if the dust discharge port 221 is configured on the rear left side of the main body 210, then the supply unit 231 can be configured on the rear right side of the main body 210.

[0137] With this configuration, when the robot vacuum cleaner 200 is combined with the robot vacuum cleaner base station 100, the robot vacuum cleaner base station 100 can simultaneously perform dust collection and water injection.

[0138] On the other hand, the nozzle (not shown) is formed of a tube or pipe and is connected to the bucket 230 so that the liquid inside the bucket 230 can flow through it. One side of the nozzle (not shown) is connected to the bucket 230, and the other end is located above or on a pair of rotating plates 241, thereby allowing the liquid inside the bucket 230 to be supplied to a pair of cloths 242 respectively.

[0139] That is, the nozzle (not shown) can be formed into a tube branching into two. In this case, the end of one tube of the branch can be located on the upper side of the left rag, and the end of the other tube of the branch can be located on the upper side of the right rag.

[0140] On the other hand, although not shown, a pump is provided in the water tank 230, which allows the water inside the water tank 230 to flow toward the nozzle (not shown). Therefore, if the pump in the water tank 230 is running, the liquid stored in the water tank 230 can be ejected through the nozzle (not shown) toward the rotating cleaning unit 240.

[0141] The rotating cleaning unit 240 includes a rotating plate 241 and a cleaning cloth 242.

[0142] The rotating plate 241 may have a pair including a left rotating plate and a right rotating plate, and the rag 242 may have a pair including a left rag and a right rag.

[0143] The rotating plate 241 can be rotatably disposed on the bottom surface of the main body 210, and the rag 242 can be attached to the lower side.

[0144] The rotating plate 241 has a defined area and is formed into a flat plate or a flat frame. This rotating plate 241 is generally horizontally positioned, thus forming a shape where the width (or diameter) in the horizontal direction is much larger than the height in the vertical direction. The rotating plate 241, attached to the main body 210, can be parallel to the floor surface or inclined to it. The rotating plate 241 can be formed into a circular plate shape, the bottom surface of which can be generally circular, and the rotating plate 241 as a whole can be rotationally symmetrical.

[0145] A pair of rotating plates 241 can achieve left-right symmetry.

[0146] The rag 242 can be attached to the underside of the rotating plate 241 to face the floor surface.

[0147] The bottom surface of the rag 242 facing the floor has a defined area, and the rag 242 is formed in a flat shape. The width (or diameter) of the rag 242 in the horizontal direction is much larger than its height in the vertical direction. As the rag 242 is attached to the side of the main body 210, the bottom surface of the rag 242 can be parallel to the floor surface or can be inclined to the floor surface.

[0148] The bottom surface of the rag 242 can be roughly circular, and the rag 242 as a whole can be rotationally symmetrical. In addition, the rag 242 can be detached from the bottom surface of the rotating plate 241, and can be attached to the rotating plate 241 to rotate together with the rotating plate 241.

[0149] On the other hand, although not shown, the rotating cleaning unit 240 may be provided with a drive unit that applies rotational force to the rotating plate 241. For example, the drive unit may have a motor and at least one gear. Therefore, when the drive unit is running, the rotating plate 241 and the mop 242 can rotate and wipe the floor surface.

[0150] The agitator 250 may be equipped with a plurality of rotating brushes that can guide external dust and air into the dust bin 220. At the same time, the agitator 250 may be equipped with at least one gear.

[0151] On the other hand, the agitator 250 of this embodiment may be equipped with an additional agitator motor (not shown) and receive rotational power. Of course, according to the embodiment, it may also receive rotational power from the driving motor or from the drive unit of the rotating cleaning unit 240.

[0152] Wheel 260 can be disposed on the bottom surface of main body 210 and can be connected to drive unit (not shown). At this time, drive unit (not shown) can be attached to main body 210.

[0153] Wheel 260 can be installed on the main body 210 and can roll on the floor surface.

[0154] Wheel 260 can be composed of a first driving wheel and a second driving wheel. In this case, the first driving wheel can be configured to be the same as the second driving wheel, or symmetrically arranged. As an example, if the first driving wheel is located on the left side of the sweeping robot 200, then the second driving wheel can be located on the right side of the sweeping robot 200. In this case, the first driving wheel and the second driving wheel can achieve left-right symmetry.

[0155] The drive unit (not shown) may include a travel motor and gears. In this case, the travel motor may be housed inside the main body 210 and provides power to the wheel 260. The travel motor may include a first travel motor and a second travel motor.

[0156] The travel motor can be an electric motor. Multiple gears mesh and rotate, connecting the travel motor and wheel 260, transmitting the rotational power of the travel motor to wheel 260. Therefore, wheel 260 can rotate when the shaft of the travel motor rotates.

[0157] With this configuration, if the driving motor is running, the wheel 260 can rotate, and the main body 210 can travel on the floor at a specified speed.

[0158] The auxiliary wheel 270 can be disposed on the lower surface of the main body 210 and can roll on the floor surface (the surface to be cleaned). The auxiliary wheel 270, together with a pair of wheels 260, can support the main body 210 on the floor surface. With this configuration, the auxiliary wheel 270 can minimize the friction between the robot vacuum cleaner 200 and the floor surface, while guiding the movement of the robot vacuum cleaner 200.

[0159] The suction motor (not shown) generates suction that draws in external dust and air through the suction section 211. For example, the suction motor (not shown) can be an electric motor. Under the suction generated by the suction motor (not shown), external dust and air flow into the suction section 211 and reach the dust bin 220 after passing through the suction flow path.

[0160] Although not shown, the battery is integrated into the main body 210 and supplies power to other components constituting the robotic vacuum cleaner 200. The battery can supply power to at least one motor disposed in the robotic vacuum cleaner 200. For example, the battery can supply power to the rotating cleaning unit 240, the agitator 250, the wheels 260, and a motor disposed in the suction motor (not shown).

[0161] In addition, the battery can supply power to the sensor unit (not shown) and the control unit 400.

[0162] The battery can be charged by an external power source, and for this purpose, a charging terminal 280 for charging can be provided on one side of the main body 210. For example, the charging terminal 280 can be configured on the rear side of the outer surface of the main body 210. If the robot vacuum cleaner 200 is combined with the robot vacuum cleaner base station 100, the charging terminal 280 can contact the power supply terminal 123b of the robot vacuum cleaner base station 100 and receive power.

[0163] Robot vacuum cleaner base station

[0164] Figure 9 A perspective view is shown illustrating the structure of a robotic vacuum cleaner base station according to an embodiment of the present invention. Figure 10 A perspective view of the door of a robot vacuum cleaner base station used to illustrate an embodiment of the present invention is shown. Figure 11A perspective view is shown illustrating the internal structure of a robotic vacuum cleaner base station according to an embodiment of the present invention. Figure 15 A diagram is shown illustrating the state in which the upper side cover is separated from the base station of the sweeping robot according to an embodiment of the present invention.

[0165] Below, refer to Figures 3 to 11 as well as Figure 15 The sweeping robot base station 100 of the present invention will be described.

[0166] The robotic vacuum cleaner 200 can be housed in the robotic vacuum cleaner base station 100. The robotic vacuum cleaner 200 can be integrated into the mounting section 120 of the robotic vacuum cleaner base station 100.

[0167] The robot vacuum cleaner base station 100 may include a cover 110.

[0168] The cover 110 can form the appearance of the robot vacuum cleaner base station 100. As an example, the cover 110 can be formed into a shape similar to a hexahedron including at least one outer wall surface.

[0169] The cover 110 can have a space inside that can accommodate the placement part 120, the door part 130, the dust collection part 140, the cloth washing part 160, the cloth drying part 170, and the air exhaust part 180.

[0170] The cover 110 can be installed on the lower side of the kitchen cabinet 2. Specifically, the cover 110 can be installed in the space formed between the lower side panel 23 of the kitchen cabinet 2 and the kitchen floor.

[0171] The enclosure 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.

[0172] As an example, a pair of outer walls 111 can be installed at predetermined intervals on the underside of the kitchen cabinet 2. In this case, the cover 110 also includes a bottom surface 112 facing the kitchen floor, and the pair of outer walls 111 can be connected through the bottom surface 112.

[0173] On the other hand, the cover 110 also includes an upper cover 113 facing the lower side panel 23 of the kitchen cabinet 2, which can be detachably attached to the upper end of a pair of outer walls 111. Therefore, even if foreign objects fall from the kitchen cabinet 2 to the lower side, it is possible to prevent the components of the robot vacuum cleaner 200 and the robot vacuum cleaner base station 100 from being contaminated.

[0174] Furthermore, the upper cover 113 can be formed by overlapping two or more panels. The inner cover 113b can refer to the bottommost panel. The inner cover 113b can cover the upper part of the accommodating space S. Additionally, the outer cover 113a can refer to the topmost panel of the upper cover 113. The outer cover 113a can face the lower panel 23 of the kitchen cabinet 2.

[0175] Additionally, the enclosure 110 may also include a rear face 111b facing the wall of the building. With this configuration, the components of the robotic vacuum cleaner base station 100 can be accommodated inside the enclosure 110 (between a pair of outer walls).

[0176] Additionally, the robotic vacuum cleaner 200 can be housed inside the enclosure 110. The enclosure 110 can be configured to have a pair of outer walls 111 with a spacing larger than the maximum horizontal width of the robotic vacuum cleaner 200. With this configuration, the robotic vacuum cleaner 200 can enter and exit the enclosure 110.

[0177] In this embodiment, the robotic vacuum cleaner 200 can enter and exit from the front of the robotic vacuum cleaner base station 100. Here, "front" can refer to the direction in which the door 131 is set with the interior of the robotic vacuum cleaner base station 100 as a reference.

[0178] Additionally, "rear" can refer to the opposite direction from the front, based on the interior of the robotic vacuum cleaner base station 100. For example, a building wall (not shown) may be located behind the robotic vacuum cleaner base station 100. Furthermore, based on the view of the robotic vacuum cleaner base station 100 from the outside, the left side can be referred to as the left side, and the right side as the right side.

[0179] That is, the outer wall 111 of the robot vacuum cleaner base station 100 can be configured on the left and right sides respectively. The outer wall configured on the left side can be referred to as the left side face 111c, and the outer wall configured on the right side can be referred to as the right side face 111d. An entrance / exit 127 for the robot vacuum cleaner 200 to enter and exit can be formed in front of the cover 110. In the cover 110, a rear face 111c can be configured on the side opposite to the entrance / exit 127.

[0180] Therefore, the upper side of the cover 110 can be covered by the kitchen cabinet 2, and the lower side of the cover 110 can be covered by the kitchen floor. In addition, the left and right sides of the cover 110 are either covered by the outer wall or located in the lower part of the kitchen cabinet 2. At this time, the lower part of the kitchen cabinet 2, except for the robot vacuum base station 100, can be finished by the baseboard 26, resulting in only the front of the cover 110 being exposed to the outside.

[0181] This minimizes the amount of the robot vacuum base station 100 and the robot vacuum 200 exposed to the outside.

[0182] With this configuration, the robot vacuum cleaner base station 100 of the present invention has the effect of providing aesthetic appeal to users in terms of decoration.

[0183] On the other hand, the cover 110 may have a space for a water supply hose connected to a water supply pipe to pass through, a space for a drainage hose to pass through for draining wastewater generated after washing the cloth 242, and a space for a hose to pass through for draining water generated during the drying process of the cloth 242. For example, the outer wall 111 of the cover 110 may have a space for a plurality of such hoses to pass through.

[0184] layout

[0185] The robot vacuum cleaner base station 100 of this embodiment is characterized in that it is installed in the lower space of the kitchen cabinet 2.

[0186] Therefore, the robot vacuum cleaner base station 100 of this embodiment is characterized in that it is configured horizontally to match the space formed between the lower side panel 23 of the kitchen cabinet 2 and the kitchen floor.

[0187] Specifically, in the robot vacuum cleaner base station 100 of this embodiment, the dust collection unit 140 and / or the cloth cleaning unit 160 can be configured on the side of the entrance 127.

[0188] At this time, with both the dust collection section 140 and the cloth cleaning section 160 provided, the placement section 120 can be arranged between the dust collection section 140 and the cloth cleaning section 160.

[0189] For example, an entrance / exit 127 and a door 131 can be configured at the front of the robot vacuum base station 100. Furthermore, a mounting section 120 can be configured, to which the robot vacuum 200 is attached from the entrance / exit 127 to the rear. In this case, the dust collection section 140 can be configured from the front to the rear of the robot vacuum base station 100 by a predetermined length. Additionally, the mop cleaning section 160 can also be configured from the front to the rear of the robot vacuum base station 100 by a predetermined length.

[0190] Therefore, when viewing the robot vacuum station 100 from the front outside, the front end of the dust collection unit 140 and / or the front end of the mop cleaning unit 160 can be arranged on the left and right sides of the entrance 127.

[0191] At this time, the dust bag drawer 144 of the dust collection unit 140 can be configured to extend outward toward the front of the cover 110. In addition, the detergent box 163 of the cloth washing unit 160 can be configured to extend outward toward the front of the cover.

[0192] On the other hand, the rear ends of the dust collection unit cover 141 and the detergent box 163 can be separated from the rear end of the cover 110 by a predetermined interval. Furthermore, a dust collection motor 145 can be arranged between the rear end of the dust collection unit cover 141 and the rear end of the cover 110. This configuration minimizes the overall space occupied by the mounting section 120, the dust collection unit cover 141, and the dust collection motor 145 within a limited space.

[0193] Furthermore, at least a portion of a flow path for washing water to flow for cleaning the cloth 242 can be configured between the rear end of the cover 110 and the rear end of the detergent dispenser 163. This configuration minimizes the path of the washing water flowing from the water supply pipe. Additionally, it minimizes the overall space occupied by the housing 120, the detergent dispenser 163, and the flow path for washing water within a limited space.

[0194] On the other hand, in the robot vacuum cleaner base station 100, the cloth drying unit 170 can be configured further rearward than the mounting unit 120. In this case, the cloth drying unit 170 can be configured between the rear end of the mounting unit 120 and the rear end of the cover 110.

[0195] Therefore, in the robot vacuum cleaner base station 100 of this embodiment, a dust collection unit 140 and a cloth washing unit 160 can be arranged on the left and right sides with the placement unit 120 as a reference, and a cloth drying unit 170 can be arranged on the rear side.

[0196] That is, in the robot vacuum cleaner base station 100 of the present invention, a dust collection unit 140, a cloth washing unit 160 and a cloth drying unit 170 can be arranged within a specified distance range from the outer contour of the placement unit 120.

[0197] This shorter distance between the dustbin 220 and the dust collection unit 140 of the robotic vacuum cleaner 200 minimizes flow path loss. Furthermore, by minimizing the distances between the mop 242 and the mop washing unit 160, and between the mop 242 and the mop drying unit 170, the area where washing water and wastewater remain after cleaning is effectively limited.

[0198] Furthermore, according to this configuration, the robotic vacuum cleaner base station 100 of the present invention can be configured with all its constituent components within a limited height.

[0199] As a result, in the robotic vacuum cleaner base station 100 of this embodiment, in addition to the front side where the robotic vacuum cleaner 200 enters, a dust collection unit 140, a mop washing unit 160, and a mop drying unit 170 can be arranged on the three sides surrounding the mounting portion 120. This configuration has the following advantages: even when the vertical height is limited, the robotic vacuum cleaner 200 can be charged using the smallest possible horizontal space; dust from the robotic vacuum cleaner 200 can also be collected; the mop 242 can be washed; and the mop 242 can be dried.

[0200] Resettlement Department

[0201] like Figures 10 to 11 As shown, the robot vacuum cleaner base station 100 may include a mounting unit 120.

[0202] The robotic vacuum cleaner 200 and the robotic vacuum cleaner base station 100 can be physically connected, electrically connected, and / or connected via the mounting unit 120.

[0203] The mounting section 120 can be installed inside the cover 110.

[0204] An entrance 127 for the robotic vacuum cleaner 200 to enter can be formed in front of the installation unit 120. The entrance 127 can refer to the space formed in front of the robotic vacuum cleaner base station 100.

[0205] The entrance / exit 127 can be formed to a size that allows the robotic vacuum cleaner 200 to pass through. That is, the height of the entrance / exit 127 is greater than the height of the robotic vacuum cleaner 200. In this case, the entrance / exit 127 may refer to a space formed vertically upward from the front end of the base 121. Alternatively, the entrance / exit 127 may refer to a hole formed in the door frame 132 described later for the robotic vacuum cleaner 200 to pass through.

[0206] At least one of a dust collection section 140 and a cloth cleaning section 160 may be disposed on the left and right sides of the entrance / exit 127. Thus, the left and right ends of the entrance / exit 127 may form boundaries with the dust collection section 140 and the cloth cleaning section 160.

[0207] At this time, entrance / exit 127 can be opened and closed by door 131.

[0208] The placement part 120 may include a receiving space S, a base 121, a connecting wall 123, and an inner wall 124.

[0209] The robotic vacuum cleaner 200 can be accommodated in the accommodating space S of the mounting section 120. As one example, the accommodating space S can be the space surrounded by the base 121, the connecting wall 123, and the inner wall 124. As another example, the accommodating space S can be the space surrounded by the base 121, the cleaning plate 122, the connecting wall 123, and the inner wall 124. As yet another example, the accommodating space S can be the space where the robotic vacuum cleaner 200 is located when it is connected to the power supply terminal 123b, or when the dustbin 220 of the robotic vacuum cleaner 200 is connected to the dust passage 123a. The accommodating space S can be the space formed between the base 121 and the upper cover 113 located on the lower side of the robotic vacuum cleaner.

[0210] The base 121 is configured to support the robot vacuum 200 when the robot vacuum base station 100 is integrated with it. The wheels 260 of the robot vacuum 200 can contact the upper side of the base 121. In addition, the auxiliary wheels 270 of the robot vacuum 200 can contact the upper side of the base 121.

[0211] The base 121 may include a base body 121a, an inclined portion 121b, a wheel engagement portion 121c, an agitator receiving portion 121d, and a cleaning tank 128.

[0212] The base body 121a can form the overall shape of the base 121. The base body 121a can be provided with an inclined part 121b, a wheel engagement part 121c, an agitator receiving part 121d, and a cleaning tank 128.

[0213] The base body 121a can be formed with a horizontal length greater than its vertical height. This structure allows the robot vacuum cleaner base station 100 to be stably supported on the floor.

[0214] A return flow path can be provided inside the base body 121a. Therefore, the air discharged from the dust collection motor 145 can flow through the return flow path 125a formed inside the base body 121a and be discharged to the air return port 125b.

[0215] The inclined part 121b can be configured in the bottom component body 121a as an entry point for the sweeping robot 200 to climb.

[0216] The inclined portion 121b may have a slope in the forward direction toward which the robotic vacuum cleaner 200 enters. More specifically, the front end of the inclined portion 121b may be connected to the ground without any height difference, while having an upward slope as it approaches the rear. That is, the inclined portion 121b may be configured to gradually rise from the ground as the robotic vacuum cleaner 200 enters. As a result, the robotic vacuum cleaner 200 can easily climb onto the robotic vacuum cleaner base station 100 from the ground.

[0217] The wheel 260 of the robotic vacuum cleaner 200, which moves upward along the wheel guide 121ba, can be mounted at the wheel engagement portion 121c. If the wheel 260 of the robotic vacuum cleaner 200 is mounted at the wheel engagement portion 121c, the robotic vacuum cleaner 200 and the robotic vacuum cleaner base station 100 can be physically connected. The surface of the wheel engagement portion 121c can be formed correspondingly to the surface of the wheel 260 to allow the robotic vacuum cleaner 200 to stop stably. The wheel engagement portion 121c can extend from the upper end of the wheel guide 121ba. The wheel engagement portion 121c can be connected to the wheel guide 121ba without any steps. Therefore, the robotic vacuum cleaner 200 can easily move to the wheel engagement portion 121c via the tilting portion 121b.

[0218] The wheel engagement portion 121c can be configured at the stop position of the left and right side wheels 260 of the robotic vacuum cleaner 200 to stop the robotic vacuum cleaner 200 in an accurate position. Here, the stop position of the wheels 260 refers to the stop position set for connecting the robotic vacuum cleaner 200 to the power supply terminal 123b and / or the stop position set for connecting the dustbin 220 of the robotic vacuum cleaner 200 to the dust passage 123a.

[0219] The shape of the wheel engagement portion 121c can be formed into an arc shape corresponding to the shape of the wheel 260 of the robotic vacuum cleaner 200. With this configuration, the robotic vacuum cleaner 200 can move along the wheel guide portion 121ba and then stop when the wheel 260 is inserted into the wheel engagement portion 121c, and the wheel 260 can be stably placed in the arc-shaped wheel engagement portion 121c.

[0220] At least a portion of the agitator 250 of the robotic vacuum cleaner 200 can be accommodated in the agitator accommodating portion 121d.

[0221] An agitator receiving portion 121d can be formed between the wheel engagement portion 121c. The agitator receiving portion 121d can be shaped to correspond to the agitator 250 of the robotic vacuum cleaner 200. The agitator receiving portion 121d can be shaped as a cuboid with an open upper portion. The bottom surface of the agitator receiving portion 121d can be sealed by the bottom surface of the base body 121a or the bottom surface of the cover 110. Thus, the agitator 250 of the robotic vacuum cleaner 200, which moves upward along the inclined portion 121b, can be placed in the agitator receiving portion 121d. At this time, the depth of the agitator receiving portion 121d can be shallower than the depth of the wheel engagement portion 121c.

[0222] The agitator receiving portion 121d can be formed as a recess in the base body 121a. Thus, when the wheels 260 of the sweeping robot 200 are mounted in the wheel engagement portion 121c, the agitator receiving portion 121d can provide space to accommodate the lower end of the agitator 250.

[0223] An air return port 125b may be formed in the agitator housing 121d. The air return port 125b may be formed on the side of the agitator housing 121d. The air return port 125b is connected to the agitator housing 121d and the dust collection motor 145 through a return flow path. The agitator housing 121d and the return flow path are connected through the air return port 125b. Therefore, air discharged from the dust collection motor 145 can be discharged to the agitator housing 121d through the air return port 125b.

[0224] The agitator housing 121d can guide the air expelled through the air return port 125b to the suction unit 211 of the robot vacuum cleaner 200.

[0225] On the other hand, the base 121 can be configured to extend out from the cover 110 and the drawer 190. In this case, the base 121 can extend out through the inlet 127 along the space between the inner walls 124.

[0226] To facilitate the removal of the base 121, a base handle 121e may be formed on the base 121. The base handle 121e may be formed between the agitator receiving portion 121d and the auxiliary wheel guide portion 121bb. Alternatively, the base handle 121e may be formed between a pair of wheel guide portions 121ba.

[0227] The base handle 121e can be formed in a recessed form of the base body 121a, and can be formed in a form that is recessed from the rear to the lower front. For example, the base handle 121e can be formed in an elliptical groove shape, and can be in a form that has a cover at the front and is open at the rear.

[0228] With this configuration, the user can easily pull out the base 121 by pulling the handle 121e.

[0229] The connecting wall 123 is configured to accommodate the dust passage 123a, power supply terminal 123b, and water nozzle 123c of the robot vacuum base station 100. The connecting wall 123 spatially separates the accommodating space S from the components of the robot vacuum base station 100. The connecting wall 123 extends vertically from the rear side of the base 121. The connecting wall 123 can be formed to correspond to the shape of the robot vacuum 200. For example, if the main body 210 of the robot vacuum 200 is cylindrical, the connecting wall 123 can be formed as an arc shape with a predetermined radius. This configuration can surround the outline of the robot vacuum 200, increasing the area of ​​the outer surface facing the robot vacuum 200. Furthermore, it can stably support the robot vacuum 200.

[0230] A dust passage 123a can be formed in the mounting section 120 to allow air from outside the cover 110 to flow inwards. Specifically, a dust passage 123a can be formed in the connecting wall 123 to allow air from outside the cover 110 to flow inwards. In this case, the dust passage 123a can be disposed behind the dust collection cover 141 described later.

[0231] The dust passage 123a can communicate with the dust bin 220 of the robotic vacuum cleaner 200. The dust passage 123a can communicate with the dust discharge outlet 221 of the dust bin 220 of the robotic vacuum cleaner 200. The dust passage 123a can be formed into a hole shape corresponding to the shape of the dust bin 220 so that the dust in the dust bin 220 flows into the dust collection section 140.

[0232] The dust passage 123a can be configured to communicate with the dust collection flow paths 147 and 148. Air drawn in through the dust passage 123a can flow through the dust collection flow paths 147 and 148 and then be discharged through the air return port 125b.

[0233] The robotic vacuum cleaner base station 100 may include a power supply module for supplying power to the robotic vacuum cleaner 200. The power supply module includes a power supply module housing and power supply terminals 123b. Circuit boards and components for supplying power may be mounted within the power supply module housing. Furthermore, the power supply terminals 123b are positioned at the front of the power supply module housing, thus being exposed on the mounting wall 123.

[0234] The power supply terminal 123b can supply power to the robotic vacuum cleaner 200 that is attached to the mounting section 120. The power supply terminal 123b can contact and be electrically connected to the charging terminal of the robotic vacuum cleaner 200. The power supply terminal 123b can be disposed in the mounting section 120. Specifically, the power supply terminal 123b can be disposed in the mounting wall 123. The power supply terminal 123b can be electrically connected to the robotic vacuum cleaner 200 attached to the mounting wall 123. The power supply terminal 123b can supply power to the battery of the robotic vacuum cleaner 200 attached to the mounting wall 123.

[0235] The robot vacuum cleaner base station 100 may also include a water supply nozzle 123c.

[0236] 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 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.

[0237] Additionally, the robotic vacuum cleaner base station 100 may also include a coupling guide 123d. The coupling guide 123d can engage with a coupling groove formed on the robotic vacuum cleaner 200 when the robotic vacuum cleaner 200 is positioned in the mounting section 120. Thus, the coupling guide 123d can guide the robotic vacuum cleaner 200 to accurately engage in the correct position. The coupling guide 123d may be disposed between a pair of external air discharge sections 173.

[0238] Additionally, the guide member 123d may include a sensor for sensing the engagement state. This allows for the detection of whether the robotic vacuum cleaner 200 is correctly positioned.

[0239] The inner wall 124 is a component that spatially divides the accommodating space S of the placement section 120 and the base station 100 of the robotic vacuum cleaner. A pair of inner walls 124 can be arranged on the left and right sides of the base 121. The inner walls 124 can be connected to both ends of the connecting wall 123. The inner walls 124 can extend from the left and right sides of the base 121 in a direction intersecting the base 121. Specifically, the inner walls 124 can extend vertically from the left and right sides of the base 121.

[0240] On the other hand, various components such as dust collection paths 147 and 148, dust collection unit 140, dust collection motor 145, detergent box 163, and wastewater tank 166 can be arranged on the outer side of the inner wall 124. Specifically, the dust collection unit 140, detergent box 163, and wastewater tank 166 can be arranged in the space between the inner wall 124 and the outer wall 111 of the cover 110.

[0241] The dust collection section 140 and the detergent dispenser 163 can be slidably separated from the space between the inner wall 124 and the outer wall 111 of the cover 110. The left-right width of the dust collection section 140 and the detergent dispenser 163 can be made smaller than the distance between the inner wall 124 and the outer wall 111 of the cover 110.

[0242] The cleaning plate 122 is a component of the cleaning cloth used to clean the robot vacuum cleaner 200, and the cleaning plate 122 can be placed in the cleaning tank 128 of the base 121. In addition, the cleaning plate 122 can contact the cleaning cloth 242 when the robot vacuum cleaner 200 is placed on it.

[0243] The cleaning plate 122 can be a plate that is generally inclined downwards towards the center.

[0244] Specifically, the cleaning plate 122 includes a flow guide surface 122c formed in a curved shape. Furthermore, at least one through-hole 122b for fluid passage can be formed in the flow guide surface 122c. Additionally, a cleaning protrusion 122a can be formed protruding from the flow guide surface 122c.

[0245] At this time, a pair of cleaning protrusions 122a can be symmetrically formed on the flow guide surface 122c. Specifically, the pair of cleaning protrusions 122a are disposed on the vertically lower side of the pair of mop pads 242 of the robot vacuum cleaner 200, facing the pair of mop pads 242, and can contact at least a portion of the pair of mop pads 242.

[0246] Furthermore, a plurality of through holes 122b may be formed on the flow guiding surface 122c, and may be formed between a pair of cleaning protrusions 122a. For example, a plurality of through holes 122b may be formed at the lowest position of the flow guiding surface 122c above the ground (kitchen floor), and may be formed between a pair of cleaning protrusions 122a. Thus, fluid expelled between the pair of cleaning protrusions 122a can be guided to the through holes 122b and flow.

[0247] On the other hand, the height of the flow guide surface 122c from the kitchen floor can increase as it moves closer to the rear of 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 moves closer to the external air exhaust portion 173, which will be described later.

[0248] With this configuration, washing water and / or air can flow along the flow guide surface 122c and flow out through the through hole 122b into the space formed between the washing plate 122 and the washing tank 128.

[0249] If washing water is supplied to the cleaning plate 122 and the cloth 242 rotates, the cloth 242 can be cleaned by rubbing against the cleaning protrusion 122a in the stopped state.

[0250] On the other hand, at least a portion of the cleaning plate 122 may be disposed on the upper side of the flow path forming portion 128c described later. That is, the cleaning plate 122 may also include a return flow path cover portion 122d, which protrudes upward from the flow guide surface 122c and is combined with the upper side of the flow path forming portion 128c.

[0251] In this embodiment, the cleaning plate 122 can be formed in a shape corresponding to the shape of the flow path forming portion 128c. For example, the front left side portion of the cleaning plate 122 can protrude upward from the flow guide surface 122c and cover the lower flow path forming portion 128c.

[0252] With this configuration, the cleaning plate 122 and the cleaning tank 128 can be accurately combined, while providing sufficient space to form the return flow path 125a.

[0253] The cleaning tank 128 is configured to house the cleaning plate 122. The cleaning tank 128 can be disposed on the rear side of the base body 121a. The cleaning tank 128 is disposed on the underside of the cleaning plate 122 and is detachably coupled to the cleaning plate 122. The cleaning tank 128 can be formed correspondingly to the cleaning plate 122 so that the cleaning plate 122 can be inserted. Liquid passing through the cleaning plate 122 can flow into the cleaning tank 128.

[0254] The cleaning tank 128 may include: a cleaning tank base surface 128a, through which fluid passing through the cleaning plate 122 flows; and a cleaning tank wall 128b, which extends vertically protruding from the outer contour of the cleaning tank base surface 128a. The height of the cleaning tank base surface 128a from the ground (kitchen floor) can be lower as it gets closer to the rear of the robot vacuum cleaner base station 100. This allows the fluid passing through the cleaning plate 122 to be collected at the rear of the cleaning tank 128 and discharged to the outside through the wastewater inlet 164c, described later.

[0255] At this time, in order to connect with the sewage inlet 164c, a sewage pipe connection port 128d can be formed on the cleaning tank wall 126b.

[0256] On the other hand, a flow path forming portion 128c can be formed in the cleaning tank 128. The flow path forming portion 128c can be formed by protruding upward from the base surface 128a of the cleaning tank, thereby forming a return flow path 125a on the lower side. Specifically, at least a portion of the return flow path 125a can be formed between the lower side of the base 121 and the flow path forming portion 128c.

[0257] On the other hand, the cleaning tank 128 of the present invention is configured to be able to be extended from the cloth cleaning section 160. That is, the cleaning tank 128 can be extended from the cover 110 together with the base 121. At the same time, the cleaning plate 122 can also be extended from the cloth cleaning section 160.

[0258] Door

[0259] Door 130 can be configured to cover the entire front end of cover 110. Door 131 can cover dust bag drawer 144 and detergent dispenser 163 so that they are not exposed to the outside.

[0260] When the entrance / exit 127 is closed, door 131 forms the front appearance of the robotic vacuum cleaner base station 100. For example, door 131 can be formed into a nearly rectangular flat shape. The length of door 131 in the left-right direction can be set to be greater than or equal to the length of the cover 110 in the left-right direction. With this configuration, the dust bag drawer 144 and detergent dispenser 163 can be protected from the outside, and the appearance of the robotic vacuum cleaner base station 100 is neat.

[0261] A door frame 132 may be provided at the front of the cover 110. The door 131 is connected to the door frame 132 in an openable and closable manner. In addition, the door frame 132 may have: an entrance 127 through which the robot vacuum cleaner 200 can enter and exit; a dust bag outlet 132a, to which a dust bag drawer 144 is connected; and a detergent dispenser insertion port 132b, to which a detergent dispenser 163 is connected.

[0262] When the door 131 is open, the door frame 132 can form the front appearance of the robot vacuum cleaner base station 100.

[0263] With the door 131 open at entrance 127, at least one side of the dust bag drawer 144 and at least one side of the detergent dispenser 163, which are coupled to the door frame 132, can be positioned to face outwards. When the door 131 is open at entrance 127, the front of the dust bag drawer 144 and the front of the detergent dispenser 163 are exposed outwards, as are the handles 144d of the dust bag drawer 144 and 163b of the detergent dispenser 163. This configuration facilitates the easy access of the dust bag drawer 144 and the detergent dispenser 163, providing a neat appearance.

[0264] The rotation axis 131a of the door 131 is located at the lower end of the door frame 132. The door 131 can be configured to be parallel to the floor surface when the entrance 127 is open, or to be formed to tilt downwards towards the front so that the end contacts the ground.

[0265] The door 131 has a hinge portion that can be rotatably connected to the door frame 132. A plurality of hinge portions can be separately arranged along the rotation axis 131a, and can be arranged separately at different intervals.

[0266] Additionally, the door 131 may have an auxiliary entry channel 131b on the side facing the cover 110 when the entrance / exit 127 is closed. The auxiliary entry channel 131b may be configured to enable the robot vacuum cleaner 200 to move stably toward the placement section 120 or the entrance / exit 127, and may be configured to tilt upwards as it moves backwards.

[0267] Specifically, to ensure stable tilting movement of the robotic vacuum cleaner 200, the auxiliary entry channel 131b can be formed in a groove shape. The grooves formed along the left-right direction of the auxiliary entry channel 131b can be evenly spaced in the front-back direction. Such an auxiliary entry channel 131b can be formed such that its width in the left-right direction decreases towards the rear. Therefore, the closer the wheels 260 of the robotic vacuum cleaner 200 are to the mounting section 120 or the entrance / exit 127, the more restricted their left-right movement becomes, and they can be guided to an accurate position.

[0268] The auxiliary entry channel 131b guides the wheel 260 to the wheel guide section 121ba disposed in the mounting section 120. The auxiliary entry channels 131b can be configured as a pair and disposed at various positions consecutive to the pair of wheel guide sections 121ba.

[0269] On the other hand, the door 131 can be driven based on whether the robot vacuum cleaner 200 approaches or starts moving, or based on the input of the door operation unit 133.

[0270] The door frame 132 is able to detect the approach of the robotic vacuum cleaner 200 by being equipped with an entry sensor 135. The entry sensor 135 can be configured in front of the housing 110 to detect the approach of the robotic vacuum cleaner 200. For example, the entry sensor 135 can be an IR sensor (infrared sensor).

[0271] The entry sensor 135 can be installed on the upper front of the door frame 132. This maximizes the sensing range. Alternatively, the entry sensor 135 can be installed in the center of the entrance / exit 127 in the left-right direction. This allows the robot vacuum cleaner 200 to be guided in its entry direction through communication with it.

[0272] On the other hand, the door 131 can be configured to be cut open at the position facing the entry sensor 135, so that the entry sensor 135 can still sense the front even when the door 131 is closed at the entrance 127. Alternatively, the door 131 can have a transmission window at the position facing the entry sensor 135.

[0273] On the other hand, door 131 can be opened during the operation of steam supply unit 169. During the period when steam supply unit 169 discharges water or wet steam into the containing space S, door 131 can be opened to supply outside air to the containing space S.

[0274] A door operating part 133 is provided in the door frame 132, which can rotate the door 131 by the user's operation.

[0275] A door operating unit 133 is disposed on the door frame 132 and may have at least one button for driving the door 131. The door operating unit 133 is capable of rotating the door 131 regardless of the position or state of the robotic vacuum cleaner 200. The door operating unit 133 may have a button for opening or closing the door 131, or may have a button for opening the door 131 and a button for closing the door 131, respectively.

[0276] The door operating part 133 can be disposed inside the door frame 132. Furthermore, the door operating part 133 can be configured such that at least one button is exposed to the outside.

[0277] At this point, the button can be positioned adjacent to the detergent dispenser 163, with the inlet / outlet as the reference point. For example, the button can be positioned on the upper side of the handle 163b of the detergent dispenser 163.

[0278] On the other hand, when the door 131 closes the entrance / exit 127, it also covers the door operation section 133. At this time, the door 131 is provided with external button sections 131c so that the door operation section 133 can be operated even when the entrance / exit 127 is closed. The external button sections 131c are configured with the same number as the buttons on the door operation section 133, and are respectively located facing the buttons. The external button sections 131c are made of a material that can elastically deform, allowing pressure to be applied to the buttons when an external force is applied.

[0279] Door 131 can be rotated via door drive unit 134. As an example, door drive unit 134 may include door drive motor and drive gear unit.

[0280] The door drive motor can be disposed inside the cover 110 and in the upper space of the detergent dispenser 163. The door drive motor can also be disposed between the detergent dispenser 163 and the upper cover 113 of the cover 110. Alternatively, the door drive motor can be disposed in front of the space between the outer wall 111 and the mounting portion 120. That is, the door drive motor can be disposed adjacent to the door operating portion 133.

[0281] This improves space utilization and accessibility, thus providing convenience for users.

[0282] The drive gear unit is configured to connect the door drive motor and the door 131 to transmit power. The drive gear unit transmits the driving force of the door drive motor to the door 131, causing the door 131 to rotate.

[0283] Dust Collection Department

[0284] The dust collection unit 140 is capable of collecting dust from the dust bin 220 of the robotic vacuum cleaner 200. The dust collection unit 140 can be disposed inside the cover 110. The dust collection unit 140 can also be disposed outside the mounting part 120. That is, the dust collection unit 140 can be disposed between the cover 110 and the mounting part 120. For example, the dust collection unit 140 can be disposed on one side of the mounting part 120 in the left-right direction.

[0285] The dust collection unit 140 may include a dust collection unit cover 141, a filter 142, a dust bag 143, a dust bag drawer 144, a dust collection motor 145, a dust collection motor cover 146, a first dust collection flow path 147, and a second dust collection flow path 148.

[0286] The dust collection unit cover 141 can form a space inside that can accommodate the filter 142, the dust bag 143, and the dust bag drawer 144.

[0287] The dust collection unit cover 141 has a dust bag drawer 144 that can be extended outwards inside, and a dust bag 143 can be stored inside the dust bag drawer 144. For example, the dust collection unit cover 141 is formed into a rectangular tube that is open at the front, and the rear internal space can be connected to the first dust collection flow path 147 and the second dust collection flow path 148.

[0288] Dust inside the dust bin 220 can flow into the dust collection unit cover 141.

[0289] One side of the interior of the dust collection hood 141 can be connected to the first dust collection flow path 147, and the other side can be connected to the second dust collection flow path 148. In addition, if a dust bag 143 is attached to the dust collection hood 141, the dust bag 143 can be connected to the first dust collection flow path 147 inside the dust collection hood 141.

[0290] The filter 142 can be installed in the dust bag drawer 144. Specifically, the filter 142 can be configured inside the dust bag drawer and extended out together with the dust bag drawer 144.

[0291] On the other hand, the filter 142 can be configured lower than the inlet 141b, with the bottom surface of the dust bag drawer body 141a as a reference. The filter 142 can be configured further forward than the outlet 144c of the dust bag drawer 144.

[0292] Specifically, the filter 142 can be detachably attached to the lower side of the dust bag drawer 144. In this case, the filter 142 can be positioned at the longitudinal (front) end of the flow path forming portion 144e. Thus, the filter 142 can be positioned between the handle 144d and the flow path forming portion 144e. That is, the filter 142 can be positioned adjacent to the front of the dust bag drawer 144.

[0293] The filter 142 can be pulled out together with the dust bag drawer 144 when the dust bag drawer 144 is pulled out. That is, the filter 142 can be pulled out together with the dust bag drawer 144 when the handle 144d is pulled out. At this time, since the filter 142 is located directly behind the handle 144d, it has the advantage that the user can easily replace the filter 142 even when only part of the dust bag drawer 144 is pulled out.

[0294] On the other hand, the filter 142 can be configured to separate from the left and right (width) sides of the dust bag drawer 144. That is, a space can be formed between the filter 142 and the left and right sides of the dust bag drawer body 144a. In this case, the user's hand can enter the space.

[0295] With the configuration described above, the filter 142 can be separated by a simple action of the user placing their finger in the space between the filter 142 and the dust bag drawer body 144a and pulling the filter 142.

[0296] The filter 142 can be positioned lower than the dust bag 143. In this case, the dust bag 143 can be combined with the dust bag drawer 144 to allow for loading and unloading in a vertically sliding manner.

[0297] Therefore, with the dust bag drawer 144 extended, the dust bag 143 can be separated from the dust bag drawer 144 in a vertical direction. If the dust bag 143 is separated, the filter 142 can be exposed to the outside.

[0298] Therefore, the user can check the status of the filter 142 every time the dust bag 143 is replaced, and can easily replace the filter 142 together with the dust bag 143.

[0299] Dust bag 143 can refer to a dust bag that collects dust sucked in from inside the dust bin 220 of the robot vacuum cleaner 200 under the action of dust collection motor 145.

[0300] The dust bag 143 can be detachably attached to the dust bag drawer 144. Therefore, the dust bag 143 can be separated from the dust bag drawer 144 and discarded, and a new dust bag 143 can be attached to the dust bag drawer 144. That is, the dust bag 143 can be defined as a consumable part.

[0301] The inlet of the dust bag 143 can be configured to communicate with the inlet 144b of the dust bag drawer 144. Thus, when the dust collection motor 145 is running, air and dust in the dust bin 220 can flow in and be captured inside the dust bag 143.

[0302] The dust bag 143 can be configured to increase in volume and contain dust when suction is generated by the dust collection motor 145. For this purpose, the dust bag 143 can be formed of a material that allows air to pass through but prevents foreign objects such as dust from passing through. For example, the dust bag can be formed of a non-woven fabric material and can have a hexahedral shape that corresponds to the shape of the dust bag drawer 144 based on the increased volume.

[0303] The dust collection unit 140 may also include a dust collection module. The dust collection module is capable of providing suction airflow to the dust collection flow path.

[0304] Specifically, the dust collection unit 140 may also include a dust collection motor 145 and a dust collection motor cover 146.

[0305] The dust collection motor 145 can generate suction on the dust collection path 147 and the dust collection path 148. That is, the dust collection motor 145 can provide suction to draw dust from the dust bin 220 into the dust bag 143 disposed in the dust collection unit cover 141.

[0306] The dust collection motor 145 can be configured behind the dust collection unit cover 141. Thus, the dust collection motor 145 can provide suction power to suck up dust from the dust bin 220 of the robot vacuum cleaner 200.

[0307] The dust collection motor 145 is capable of generating suction by rotation. As an example, although not shown, the dust collection motor 145 may include a rotor and a stator that rotate relative to each other when a power source is applied, and may include an impeller that rotates about a rotation axis as the rotor rotates. Therefore, suction can be generated by the rotation of the impeller.

[0308] One side of the dust collection motor 145 can be connected to the second dust collection flow path 148, and the other side can be connected to the return flow path 125a. When the dust collection motor 145 is driven, the air flowing in the second dust collection flow path 148 can flow into the interior of the dust collection motor housing 146. In addition, the air flowing into the interior of the dust collection motor housing 146 can flow in the return flow path 125a after passing through the dust collection motor 145.

[0309] On the other hand, in this embodiment, the rotation axis of the dust collection motor 145 can be arranged in a vertical direction. In this case, the horizontal space occupied by the dust collection motor 145 can be minimized.

[0310] On the other hand, when the rotating shaft of the dust collection motor 145 is arranged in a vertical direction, it can be configured such that the height of the air flowing into the dust collection motor 145 is different from the height of the air exiting the dust collection motor 145. As a result, a structure for the dust collection motor cover 146 can be formed.

[0311] The dust collection motor cover 146 can internally house the dust collection motor 145. The dust collection motor cover 146 can be positioned behind the dust collection section cover 141. Alternatively, the dust collection motor cover 146 can be positioned behind the first dust collection flow path 147. Additionally, the dust collection motor cover 146 can be positioned behind the second dust collection flow path 148.

[0312] That is, taking the front-to-back direction of the robot vacuum base station 100 as a reference, the dust collection unit cover 141 can be positioned at the front, and the first dust collection flow path 147 and the second dust collection flow path 148 can be positioned behind the dust collection unit cover 141. Furthermore, a dust passage 123a can be positioned further rearward than the first dust collection flow path 147, and a dust collection motor cover 146 can be positioned further rearward than the second dust collection flow path 148. Additionally, the dust collection motor cover 146 can be positioned further rearward than the dust passage 123a.

[0313] Therefore, the dust collection unit 140 is configured along the front-rear direction of the robot vacuum cleaner base station 100, thereby reducing the overall height.

[0314] On the other hand, the dust collection unit 140 may also include a dust collection flow path 147 and a dust collection flow path 148. The dust collection flow path may refer to the flow path through which air drawn in through the dust through-hole 123a flows through the dust bag to the dust collection motor 145.

[0315] Specifically, the dust collection path may include: a first dust collection path 147 that connects the dust bin 220 to the internal space of the dust collection unit cover 141 when the sweeping robot 200 is combined with the sweeping robot base station 100 and the dust through hole 123a is connected to the dust bin 220 of the sweeping robot 200; and a second dust collection path 148 that connects the internal space of the dust collection unit cover 141 to the internal space of the dust collection motor cover 146.

[0316] The first dust collection path 147 connects the dust bin 220 of the robotic vacuum cleaner 200 to the internal space of the dust collection cover 141. The first dust collection path 147 also connects the dust passage 123a of the placement part 120 to the internal space of the dust collection cover 141. The first dust collection path 147 can be formed in a direction intersecting the vertical direction. For example, the first dust collection path 147 can be formed in a direction close to the horizontal direction. The first dust collection path 147 can be a space formed rearward from the dust passage 123a, or a path that bends laterally from the dust passage 123a and allows dust and air to flow. Dust in the dust bin 220 of the robotic vacuum cleaner 200 can be moved to the internal space of the dust collection cover 141 through the first dust collection path 147.

[0317] The second dust collection path 148 connects the internal space of the dust collection unit cover 141 with the internal space of the dust collection motor cover 146. The second dust collection path 148 can be formed in a direction intersecting the vertical direction. For example, the second dust collection path 148 can be formed in a direction close to the horizontal direction.

[0318] In this invention, the first dust collection path 147 and the second dust collection path 148 can be formed at different heights. That is, the first dust collection path 147 and the second dust collection path 148 can be configured in a stacked structure. Specifically, at least a portion of the first dust collection path 147 can be disposed above the second dust collection path 148.

[0319] This configuration allows for the arrangement of multiple flow paths in a near-horizontal direction, thereby reducing the overall height. Simultaneously, these paths can be stacked to minimize the lateral width and overall volume of the robotic vacuum cleaner base station 100.

[0320] Cleaning section

[0321] On the other hand, the cleaning unit 160 of the robot vacuum cleaner base station 100 according to an embodiment of the present invention will be described as follows.

[0322] The robot vacuum cleaner base station 100 of this embodiment may include a cloth cleaning unit 160. The cloth cleaning unit 160 is capable of supplying washing water to the cloth 242 of the robot vacuum cleaner 200 attached to the mounting unit 120 to clean the cloth 242, and discharging the wastewater after cleaning the cloth 242.

[0323] The cloth cleaning unit 160 may include a washing water supply unit that mixes detergent-containing liquid with clean water and dispenses it onto the upper side of the cleaning plate 122. The washing water supply unit may include a regulator 161, a mixing chamber 162, a detergent box 163, a branch flow path 164, and a washing water nozzle 165.

[0324] At this time, the detergent dispenser 163 and the wastewater tank 166 can be accommodated in the space formed between the inner wall 124 and the outer wall 111 of the cover. The detergent dispenser 163 can be disposed on the lower side of the space between the inner wall 124 and the outer wall 111 of the cover, and the wastewater tank 166 can be disposed on the upper side of the detergent dispenser 163.

[0325] The water supply pipe of the kitchen cabinet 2 is connected to the regulator 161, which can regulate the flow rate supplied from the water supply pipe. In addition, a portion of the purified water after passing through the regulator 161 can be supplied to the water tank 230 of the robot vacuum cleaner 200 through the water supply nozzle 123c, and the remainder can be supplied to the mixing chamber 162.

[0326] Additionally, the detergent-containing liquid stored in the detergent dispenser 163 can be supplied to the mixing chamber 162 via a pump-driven flow mechanism. The detailed structure of the detergent dispenser 163 will be described later.

[0327] The mixing chamber 162 has a space that allows liquid containing detergent and purified water to flow in and mix separately, and can discharge washing water mixed with detergent and purified water. Such a mixing chamber 162 may have a purified water inlet 162a, a detergent inlet 162b, and a branch flow path connection port 162c.

[0328] The mixing chamber 162 is located inside the housing 110 and can be positioned further rearward than the mounting section 120. In this case, a flow path 161a for purified water to flow from the regulator 161 can be connected to the purified water inlet 162a. Additionally, a flow path 163a for detergent-containing liquid to flow from the detergent dispenser 163 is connected to the detergent inlet 162b. Therefore, the pumps of the regulator 161 and the detergent dispenser 163 can operate for a certain period of time to allow a preset amount of purified water and detergent to flow into the mixing chamber 162.

[0329] On the other hand, the branch flow path connection port 162c can be connected to the branch flow path 164. The branch flow path 164 is capable of supplying washing water mixed with purified water and detergent to a pair of washing water nozzles 165 respectively.

[0330] The branch flow path 164 can be configured as one pipe branching into two pipes. In this case, the end of any one pipe of the branch is connected to any one of the washing water nozzles 165 in a pair of washing water nozzles, and the end of the other pipe of the branch can be connected to the remaining one of the washing water nozzles 165 in a pair of washing water nozzles.

[0331] The washing water nozzles 165 can be configured in pairs. Here, a pair of washing water nozzles 165 can be configured in symmetrical positions.

[0332] Furthermore, the washing water nozzle 165 can be connected to a branch flow path 164, through which washing water flows into the interior of the branch flow path 164 and is discharged onto the cleaning plate 122. The washing water nozzle 165 can discharge washing water onto the upper surface of the cleaning plate 122 through the washing water discharge port 165a. The washing water discharge port 165a can open towards the upper surface of the cloth 242 placed on the cleaning plate 122. More specifically, the washing water discharge port 165a formed in the washing water nozzle 165 can discharge washing water into the cleaning protrusion 122a of the cleaning plate 122.

[0333] The washing water nozzle 165 can be disposed on the nozzle mounting wall connected to the connecting wall 123. The washing water nozzle 165 can be located at a position higher than the uppermost end of the cleaning plate 122 so that it can be disassembled and assembled with the cleaning plate 122. Thus, when the cleaning plate 122 is disassembled or the drawer 190 is pulled out, the cleaning plate 122 and the cleaning tank 128 do not collide with the washing water nozzle 165, and there can be a space for washing water to be discharged between the nozzle mounting wall and the cleaning plate 122.

[0334] Furthermore, the washing water nozzle 165 can be configured to separate vertically upwards from the center of the cleaning protrusion 122a in the width direction. Specifically, when the rotation direction of the cloth 242 during the washing process is set to one direction, the washing water nozzle 165 can be configured to separate from the center of the cleaning protrusion 122a in the width direction in another direction. With this configuration, the washing water can flow along the center of the cleaning protrusion 122a in the width direction.

[0335] The detergent dispenser 163 includes a detergent dispenser body 163a, a handle 163b, and a detergent dispenser guide rail 163c.

[0336] The detergent dispenser body 163a provides space for storing liquid containing detergent. For example, the detergent dispenser body 163a can be shaped like a box with an open top.

[0337] A handle 163b may be provided at the front of the detergent dispenser body 163a. ​​The handle 163b may be configured to be gripped by a user. For example, the handle 163b may be recessed from the front of the detergent dispenser body 163a toward the rear.

[0338] With this configuration, when the user grasps the handle 163b and pulls it forward, the detergent dispenser body 163a can also be pulled forward and extended. Therefore, according to the present invention, the user can easily pull the detergent dispenser 163 forward, and then detergent can be dispensed.

[0339] A detergent dispenser guide rail 163c may be formed on the detergent dispenser body 163a. ​​The detergent dispenser guide rail 163c can guide the movement of the detergent dispenser body 163a.

[0340] For example, the detergent dispenser guide rail 163c can be formed in the left and right sides of the detergent dispenser body 163a in the front-back direction as a groove or rib.

[0341] With this configuration, when the user attaches the detergent dispenser 163 to the cover 110, the detergent dispenser 163 can be attached to the correct position, and water leakage can be prevented.

[0342] On the other hand, although not shown, a guide rail can be formed on the cover 110 corresponding to the detergent dispenser guide rail 163c. The guide rail can be formed to correspond to the shape and position of the detergent dispenser guide rail 163c.

[0343] The wastewater tank 166 provides space for storing the washing water after washing the cloth 242. The washing water discharged onto the upper surface of the washing plate 122 can drain into the through-hole 122b as it descends along the inclined surface of the washing plate 122 after washing the cloth 242. The washing water through the through-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 166b through the wastewater inlet 166a, and then into the wastewater tank 166 through the wastewater inlet 166b. In other words, the liquid passing through the washing plate 122 can flow along the washing tank 128 and be discharged through the wastewater inlet 166a.

[0344] On the other hand, a sewage suction flow path 166b is formed in the sewage suction pipe, with a sewage inlet 166a formed at one end of the sewage suction pipe, and the other end of the sewage suction pipe communicating with the sewage tank 166. In this case, the sewage suction pipe can be configured to pass under the cloth drying section 170. That is, the sewage suction flow path 166b can be configured under the cloth drying section 170. Alternatively, the sewage suction flow path 166b can be configured under the external air supply flow path 171.

[0345] Washing water stored in the wastewater tank 166 can be discharged to the drain pipe 25 of the kitchen cabinet 2 through the wastewater discharge passage 167. One end of the wastewater discharge passage 167 can be connected to the wastewater tank 166, and the other end can be connected to the drain pipe 25. At this time, the washing water stored in the wastewater tank 166 can be discharged to the drain pipe 25 by using a centrifugal pump (not shown) to flow through the wastewater discharge passage 167.

[0346] The sewage discharge path 167 connected to the sewage tank 166 can be connected upstream 25b with reference to the U-bend 25a of the drain pipe 25 of the kitchen cabinet 2. This is because if the sewage discharge path 167 is connected downstream 25c with reference to the U-bend 25a of the drain pipe 25, foul odors or fluids inside the drain pipe 25 may flow back into the sewage discharge path 167.

[0347] Additionally, the cloth washing unit 160 may include a check valve (not shown). The check valve prevents fluid inside the drain pipe 25 from flowing back into the sewage discharge path 167. The check valve may be located at the other end of the sewage discharge path 167 connected to the drain pipe 25.

[0348] On the other hand, the mop cleaning unit 160 of the robot vacuum cleaner base station 100 of the present invention may also include a steam supply unit 169.

[0349] The steam supply unit 169 can receive purified water using the regulator 161 and heat the water internally. The steam supply unit 169 can sterilize the cloth 242 by discharging heated water into the receiving space S. Alternatively, the steam supply unit 169 can heat water to over 100 degrees Celsius to generate humid steam. The steam supply unit 169 can sterilize the cloth 242 by discharging humid steam into the receiving space S.

[0350] A steam supply unit 169 can be disposed between the cloth drying unit 170 and the dust collection motor housing 110. The nozzles of the steam supply unit 169 can be disposed on the nozzle mating wall. A heater coil can be included inside the steam supply unit 169 to heat water. This allows for a stable supply of water or humid air maintained at a specified temperature.

[0351] In addition, the steam supply unit 169 can receive water through the water supply pipe, and the water discharged after use can be discharged into the sewage tank 166 through the drain pipe.

[0352] Cloth Drying Section

[0353] Figure 12 A top view of the cloth drying section of a robot vacuum cleaner base station used to illustrate an embodiment of the present invention is shown. Figure 13 It shows along Figure 12 A sectional view cut along line AA. Figure 14 It shows along Figure 12 A sectional view cut along the BB line.

[0354] Reference Figures 12 to 14 In one embodiment of the present invention, the robot vacuum cleaner base station 100 may include a cloth drying unit 170. At this time, the cloth drying unit 170 can dry the cloth 242 of the robot vacuum cleaner 200 that has been cleaned by the cloth washing unit 160 or the cloth 242 that is wet after the water cleaning operation is completed.

[0355] The cloth drying unit 170 can heat air and supply it to the receiving space S. The cloth drying unit 170 may include an external air supply flow path 171, an external air inlet 172, an external air outlet 173, a heater 174, and a blower fan 175.

[0356] An external air supply path 171 is formed in the cloth drying section 170. The external air supply path 171 allows air to flow to the external air discharge section 173.

[0357] The external air supply path 171 can discharge air into the receiving space. The other side of the external air supply path 171 can communicate with the receiving space S via the external air discharge section 173. The external air supply path 171 can discharge air flowing in from the front, lower side, or rear of the enclosure 110 through gaps into the receiving space S. A blower fan 175 and a heater 174 can be sequentially arranged on the external air supply path 171. The height of the external air supply path 171 can decrease as the blower fan 175 approaches the heater 174.

[0358] With this configuration, the airflow velocity through the external air supply path 171 can be increased. This, in turn, improves the heating efficiency of the heater 174.

[0359] An external air inlet 172 may be formed on the rear side 111b of the cover 110. Air outside the cover 110 can flow into the external air supply path 171 through the external air inlet 172. As another example, the cover 110 may not include additional features for external air inflow. That is, air can flow in through gaps formed on the front, lower side, or rear side of the cover 110. Thus, air outside the cover 110 can flow into the interior of the cover 110.

[0360] At least a portion of the external air exhaust section 173 may be disposed on the upper side of the cleaning plate 122. The external air exhaust section 173 may open in a direction facing the cleaning plate 122. A pair of external air exhaust sections 173 may be provided in a downward-opening state. A pair of external air exhaust sections 173 may be formed symmetrically about an imaginary axis a1 extending the rotation axis of the air supply fan 175.

[0361] The external air outlet 173 can discharge air that has passed through the external air supply path 171. The external air outlet 173 can be disposed in front of the heater 174. The external air outlet 173 can discharge air heated by the heater 174 into the receiving space S. The air heated by the heater 174 can be branched to the left and right and discharged through a pair of external air outlets 173a.

[0362] With this configuration, a pair of external air exhaust sections 173 can dry the mop 242, which is symmetrically arranged on the lower side of the robot vacuum 200. Furthermore, it prevents heat from being concentrated in a specific area, thus improving the drying efficiency of the mop 242.

[0363] In particular, the external air discharge section 173 can be configured to slope downwards as it approaches the front of the robot vacuum base station 100. That is, the external air discharge section 173 can be configured to slope downwards as it moves away from the heater 174. Therefore, the end of the external air discharge section 173 that discharges air can be formed to be inclined at a predetermined angle relative to the ground. This angle can be 90 degrees or less. Thus, the external air discharge section 173 can discharge air in a direction intersecting the direction formed by the flow guide surface 122c.

[0364] For example, an external air outlet 173a may be formed in the external air outlet 173. The external air outlet 173a may refer to the open portion of the external air outlet 173. The external air outlet 173a can discharge air toward the cleaning plate 122. With the cleaning cloth 242 placed on the cleaning plate 122, the external air outlet 173 can open toward the upper side of the cleaning cloth 242. Thus, the external air outlet 173 is located adjacent to the cleaning cloth 242 and opens downward, so that the air discharged from the external air outlet 173 can flow toward the cleaning cloth 242.

[0365] On the other hand, the external air outlet 173a can be penetrated by an imaginary plane C, including an imaginary line connecting the left and right portions constituting the maximum width of the blower fan 175 and the blower fan axis a1. In one embodiment of the present invention, the blower fan 175 can be configured in an inclined state. More specifically, the blower fan 175 can be configured inclined so that the surface discharging air faces the ground. Furthermore, the external air outlet 173 can be configured to tilt downwards as it moves away from the heater 174. Thus, the plane C including the blower fan axis a1 can be formed to penetrate the downwardly opening external air outlet 173a.

[0366] This configuration shortens the airflow path from the blower fan 175 to the cloth 242 via the external air outlet 173a. Furthermore, drying efficiency can be improved by increasing the velocity of the heated air delivered to the cloth 242.

[0367] On the other hand, a grille can be provided in the external air outlet 173 to guide the air outlet direction. This prevents heated air from being concentrated and discharged to a specific location.

[0368] The air supply fan 175 can be configured on the external air supply path 171 and blow air into the accommodating space S. The air supply fan 175 can provide aerodynamic force for the air flowing in from the gaps in the enclosure 110.

[0369] The blower fan 175 can cause air to flow towards the external air outlet 173. If the blower fan 175 is driven, the air can be heated by the heater 174 and discharged into the receiving space S through the external air outlet 173. The blower fan 175 can be an axial flow fan. The air discharge direction of the blower fan 175 can be parallel to the rotation axis. The air intake direction of the blower fan 175 can be parallel to the air discharge direction.

[0370] This configuration simplifies the airflow path by aligning the intake and exhaust directions. Furthermore, it provides the same airflow even at relatively low rotational speeds. Therefore, compared to using a centrifugal fan, a smaller blower fan 175 can be used. Consequently, the space occupied by the blower fan 175 can be minimized, and the number of required components can be reduced.

[0371] An air supply fan 175 can be disposed between the rear surface 111b of the housing 110 and the heater 174. The air supply fan 175 can be configured to have a predetermined slope relative to the rear surface 111b. Within the housing 110, the air supply fan 175 can be configured with the air exhaust surface facing the receiving space S. The air supply fan 175 can be tilted so that the air exhaust surface faces the ground.

[0372] In detail, the imaginary air supply fan axis a1 extending the rotation axis of the air supply fan 175 can form a predetermined slope relative to the ground. The air supply fan axis a1 can form a predetermined slope with the rear surface 111b. The air supply fan axis a1 can pass through the heater 174.

[0373] At least a portion of the air supply fan 175 can be separated from the rear surface 111b. The air supply fan 175 can be configured to tilt at a predetermined angle relative to the rear surface 111b. Thus, the distance between the uppermost point of the air supply fan 175 and the rear surface 111b can be greater than the distance between the lowermost point of the air supply fan 175 and the rear surface 111b.

[0374] On the other hand, if the maximum distance between the air supply fan 175 and the rear face 111b is ensured to be above a specified level, airflow can be smoothly formed. That is, the FMC (Fan Motor Control) performance degradation under the maximum output conditions of the heater can be minimized. In particular, it has the effect of maintaining the FMC performance degradation rate at -1.47% when the distance between the air supply fan 175 and the rear face 111b is 30mm.

[0375] If the maximum distance between the air supply fan 175 and the rear surface 111b is set to less than 25 mm, the airflow will not be smooth, and there is a high possibility that the air around the heater 174 will stagnate. Therefore, the temperature of the heater 174 may rise above 112°C, and the temperature of the surface in the air supply fan 175 where exhaust air occurs will also increase by more than 30°C, leading to an increased load on the air supply fan 175 and a potential risk of overheating. Furthermore, the temperature of the external air outlet 173a may rise above 73°C, increasing the likelihood of obstructed airflow.

[0376] When the maximum distance between the blower fan 175 and the rear surface 111b exceeds 35mm, although the airflow is smooth, the excessive distance to the rear surface 111b may reduce the air intake efficiency of the blower fan 175. Specifically, the heat transfer efficiency of the heater 174 decreases due to the excessive increase in airflow caused by the blower fan 175. Furthermore, with an excessively large distance between the blower fan 175 and the rear surface 111b, it is difficult to effectively utilize the internal space of the enclosure 110, and the volume occupied by the cloth drying section 170 increases.

[0377] Therefore, in the robotic vacuum cleaner base station 100 of one embodiment of the present invention, the maximum distance between the air blower 175 and the rear face 111b can be set to 25mm or more and 35mm or less. This ensures stable airflow and maintains the temperature of the heater 174 at an appropriate level. Furthermore, the performance of the air blower 175 can be optimized.

[0378] On the other hand, the blower fan 175 can operate during the operation of the steam supply unit 169. While the steam supply unit 169 discharges water or humid steam into the housing S, the blower fan 175 can operate to supply outside air to the housing S. When the blower fan 175 is operating to supply outside air, the heater 174 can remain stopped. Furthermore, the operation of the blower fan 175 can be controlled by the control unit 400. The exhaust fan 183 operates based on humidity information measured by the humidity sensor 177.

[0379] Heater 174 can be configured on external air supply path 171 and heat the air flowing in external air supply path 171. Heater 174 can heat air. Heater 174 can heat air discharged through external air outlet 173.

[0380] The heater 174 may include a heater housing and a heating element. The heater housing may be positioned on the external air supply path 171, and a space capable of accommodating the heating element may be provided inside the heater housing. Furthermore, the heating element can heat the air flowing into the heater housing. Thus, the air heated by the heating element can be discharged through the external air outlet 173 into the accommodating space S, drying the wet cloth 242.

[0381] Air exhaust section

[0382] The air heated by the hot air expelled from the cloth drying section 170 can be discharged through the exhaust section 180.

[0383] At least a portion of the air exhaust section 180 may be disposed on the upper part of the accommodating space S.

[0384] The air heated by the hot air expelled from the cloth drying section 170 can heat the cloth 242 of the robot vacuum cleaner 200. As a result, any residual moisture absorbed by the cloth 242 can absorb heat from the air and vaporize. This vaporized moisture can then flow within the containment space S. Therefore, the air within the containment space S can contain vaporized moisture, and the humidity within the containment space S can increase (hereinafter, the air containing vaporized moisture within the containment space S can be referred to as "wet steam").

[0385] The air exhaust section 180 can exhaust air from the accommodating space S to the outside. Specifically, at least a portion of the air exhaust section 180 can be disposed on the upper cover 113, which can cover the upper part of the accommodating space S.

[0386] The air heated by the hot air expelled from the cloth drying section 170 causes the moisture in the cloth 242 to vaporize, resulting in an increased humidity level. Therefore, if the robot vacuum base station 100 is located under the kitchen cabinet 2, the humid steam will come into contact with various components of the kitchen cabinet 2, such as the foot plate 26, and will have an adverse effect on these components.

[0387] In this embodiment, the upper cover 113 covers the upper part of the accommodating space S, while the door 126 covers the front of the accommodating space S. Therefore, the upper cover 113 and the door 126 together prevent the humid steam in the accommodating space S from flowing out to the outside, thereby preventing the kitchen cabinet 2 from coming into contact with the humid steam.

[0388] The air exhaust section 180 may include an air intake 181, an air exhaust duct 182, and an exhaust fan 183.

[0389] Air intake 181 can communicate with the containment space S. Air intake 181 can be disposed on the upper side of the containment space S. Wet vapor in the containment space S can be discharged through air intake 181. Air can be drawn into the containment space S using air intake 181.

[0390] With the robot vacuum cleaner 200 positioned in the mounting section 120, the air intake 181 can be positioned higher than the robot vacuum cleaner 200 itself. This improves the efficiency of drawing in the rising convection steam generated during the drying of the mop.

[0391] As an example, an air intake 181 can be formed on the upper cover 113. In this case, the upper cover 113 can be formed in the form of two or more overlapping plates, wherein the inner cover 113b, which is the lowermost plate, can have an air intake 181 formed, and a flow path communicating with the air intake 181 can be formed between the inner cover 113b and the outer cover 113a to form an air exhaust pipe 182.

[0392] In addition, the height of the air intake 181 above the ground can be higher than the height of the external air exhaust 173a above the ground.

[0393] As another example, an air intake 181 may be formed on a circular or quadrilateral tubular air exhaust duct 182, which may be combined with an upper cover 113.

[0394] With this configuration, when the upper cover 113 is separated, the air exhaust pipe 182 can be separated together with the upper cover 113. This has the advantage that when the upper part of the robot vacuum base station 100 needs to be opened for reasons such as repair, the air exhaust pipe 182 can be removed by the simple action of the operator lifting the upper cover 113.

[0395] An air intake 181 can be formed in the shape of a hole on the upper cover 113. The air intake 181 can be a circular hole. The exhaust fan housing can be directly connected to the hole portion of the air intake 181. Thus, air flowing in through the air intake 181 can immediately flow into the exhaust fan housing. The air drawn in through the air intake 181 can flow into the exhaust fan 183. The distance from the external air outlet 171c to the air intake 181 can be greater than the distance from the external air outlet 171c to the cloth 242. This is to prevent heated air discharged from the external air outlet 171c from being directly drawn into the air intake 181 without being adequately supplied to the cloth 242, thus avoiding energy waste.

[0396] Furthermore, the air intake 181 can be configured to be closer to the door 131 than the external air exhaust 171c. By positioning the air intake 181 at the upper front of the accommodating space S, the flow range of the hot air exhausted from the external air exhaust 173 is widened, thus improving the drying efficiency of the mop 242. Consequently, the hot air exhausted through the external air exhaust 173 can dry the mop 242 of the robot vacuum 200 as it flows forward, and then exit from the air intake 181.

[0397] Additionally, the air intake 181 can be positioned above the path along which the robotic vacuum cleaner 200 moves within the enclosure 110. This prevents condensation from forming on the inner walls of the enclosure 110.

[0398] As an example, at least a portion of the air intake 181 can be positioned vertically above the location where the sweeping robot 200 has the widest lateral width when it is positioned in the mounting section 120. That is, at least a portion of the air intake 181 can be positioned above the location where the gap between the sweeping robot 200 and the pair of inner walls 124 is narrowest. In this case, at least a portion of the air intake 181 can be positioned further forward than the cleaning plate 122.

[0399] This prevents steam generated during the drying process of the mop 242 from flowing towards the front of the robot vacuum base station 100, and prevents moisture from penetrating into the sensors located in front of the robot vacuum 200 and causing erroneous actions.

[0400] The air exhaust duct 182 can connect to the exhaust fan 183 and the air exhaust outlet 184 and connect to the drain pipe 25 of the kitchen cabinet 2. The air exhaust duct 182 can guide the wet steam discharged through the air intake 181 to the drain pipe 25.

[0401] One side of the air exhaust duct 182 can be connected to the air intake 181, and the other side can be connected to the air exhaust outlet 184. An exhaust fan 183 can be installed on the air exhaust duct 182. An air exhaust flow path communicating with the air intake 181 can be formed inside the air exhaust duct 182.

[0402] The exhaust fan 183 can cause air in the containment space S to flow towards the air intake 181. It can also generate airflow from the air intake 181 to the drain pipe 25. The exhaust fan 183 can generate airflow so that wet steam in the containment space S can be drawn in from the air intake 181 and then discharged to the outside through the air exhaust pipe 182.

[0403] The exhaust fan 183 may include an exhaust fan housing, a shaft, a fan motor, and an impeller. A flow path communicating with the air exhaust duct 182 may be formed inside the exhaust fan housing. If the exhaust fan motor actuates, causing the exhaust fan impeller to rotate, air from the accommodating space S or the housing 110 flows into the air exhaust duct 182 and is discharged from the air outlet 184 through the interior of the exhaust fan housing.

[0404] On the other hand, in this embodiment, the exhaust fan 183 can be configured above the path along which the robotic vacuum cleaner 200 moves within the enclosure. For example, the exhaust fan 183 can be configured on the upper cover 113. The exhaust fan enclosure can be configured between the outer cover 113a and the inner cover 113b included in the upper cover 113.

[0405] The imaginary exhaust fan axis a2 of the rotating shaft included in the extended exhaust fan 183 can be configured to be perpendicular to the ground. That is, the air intake direction of the exhaust fan 183 can be perpendicular to the ground.

[0406] On the other hand, in this embodiment, the exhaust fan 183 can be a centrifugal fan. Within the housing 110, the air intake surface of the exhaust fan 183 can be configured to face the receiving space S. The air discharge direction of the exhaust fan 183 can be perpendicular to the rotation axis. The air intake direction of the exhaust fan 183 can be perpendicular to the air discharge direction. If the exhaust fan 183 is driven, air in the receiving space S can flow in from the air intake 181. The air flowing in from the air intake 181 can be discharged to the drain pipe 25.

[0407] At this time, the air outlet 184 can be formed in a shape that opens to the rear of the cover 110. Condensation caused by the wet steam discharged through the air outlet 184 can collect along the inclined surface of the mounting joint 114 formed on the cover 110. The air discharged from the air outlet 184 can diffuse into the outside air.

[0408] On the other hand, the exhaust fan 183 can operate during the operation of the steam supply unit 169. While the steam supply unit 169 is discharging water or humid steam into the containing space S, the exhaust fan 183 can operate to regulate the humidity inside the robot vacuum base station 100. The operation of the exhaust fan 183 can be controlled by the control unit 400. The exhaust fan 183 can operate based on humidity information measured by the humidity sensor 177.

[0409] drawer

[0410] When the charging dock of the robotic vacuum cleaner is positioned under the kitchen cabinet, its external exposure is minimized, thus enhancing the aesthetic appeal. However, if the robotic vacuum cleaner malfunctions while inside the cabinet or if the charging dock itself malfunctions, it presents a limitation that makes it difficult for the user to remove and repair it. To address this issue, a drawer 190 can be added to the robotic vacuum cleaner base station 100 in this invention.

[0411] The robot vacuum cleaner base station 100 of one embodiment of the present invention may further include a drawer 190 extending from the cover 110.

[0412] Drawer 190 can be moved relative to cover 110. For example, cover 110 can be fixedly attached to kitchen cabinet 2, and drawer 190 can be pulled out from cover 110 forward.

[0413] At this time, drawer 190 can be drawn out with the internal storage section 120. With this configuration, when drawer 190 is drawn out, the storage section 120 and / or the robot vacuum cleaner 200 can be drawn out from the kitchen cabinet 2 to the outside.

[0414] At this time, when the drawer 190 is pulled out of the cover 110 with the door 131 closing the entrance 127, the upper cover 113 can be exposed to the outside. At this time, if the upper cover 113 is disassembled, the robot vacuum cleaner 200 can be exposed to the outside.

[0415] Therefore, according to this embodiment, when the robot vacuum base station 100 needs to be repaired or cleaned, the user can easily pull out the installation part 120 and / or the robot vacuum 200 through the drawer 190, thereby exposing the internal components of the robot vacuum base station 100 or the robot vacuum 200.

[0416] On the other hand, in one embodiment of the present invention, the drawer 190 can be drawn out while the dust collection section 140 is provided inside. In this case, the drawing direction of the drawer 190 can be parallel to the drawing direction of the dust bag drawer 144.

[0417] In another embodiment of the present invention, the drawer 190 can be drawn out together with the dishcloth washing unit 160. Specifically, the drawer 190 can be drawn out together with the detergent dispenser 163. In this case, the direction in which the drawer 190 is drawn out can be parallel to the direction in which the detergent dispenser 163 is drawn out.

[0418] With this configuration, the robot vacuum cleaner base station 100 of an embodiment of the present invention can be configured such that the drawer 190, dust bag drawer 144 and detergent box 163 are all parallel in their outward directions.

[0419] Therefore, it has the effect that users can easily identify the lead-out direction of the constituent elements of the robot vacuum cleaner base station 100 of the present invention and can easily lead them out for repair and maintenance.

[0420] Drawer 190 includes drawer sidewalls 191, fitting part 192, and drawer slides 193.

[0421] The drawer sidewalls 191 are configured to be movable relative to each other between the drawer sidewalls 191 and the outer wall of the cover 110. For example, a pair of drawer sidewalls 191 may be configured to face the outer wall of a pair of covers 110.

[0422] Here, a pair of drawer sidewalls 191 can be positioned closer to the inner side of the robot vacuum base station 100 than the outer walls of the pair of covers 110. That is, the pair of drawer sidewalls 191 can be positioned closer to the mounting portion 120 than the outer walls of the pair of covers 110.

[0423] On the other hand, a dust collection section 140 and / or a cloth cleaning section 160 may be provided between the drawer side wall 191 and the placement section 120.

[0424] This configuration allows for the efficient use of minimal horizontal space to arrange the dust collection unit 140 and the cloth washing unit 160.

[0425] Drawer guide rails 193 are disposed on the drawer side wall 191 and can guide the movement of the drawer side wall 191. Drawer guide rails 193 can be fixedly attached to or integrally formed on the drawer side wall 191, and can be combined with guide rails provided on the outer wall 111 of the cover 110 to guide the movement path of the drawer side wall 191. On the other hand, although the present invention describes the presence of guide rails in the drawer 190 and the cover 110, it is not necessarily limited to the form of guide rails, and can include all forms that can replace guide rails, such as rollers, guide grooves, or guide ribs.

[0426] Control Structure

[0427] Figure 16 A block diagram illustrating the control configuration in a robot vacuum cleaner base station according to an embodiment of the present invention is disclosed.

[0428] The following is for reference Figure 16 This section explains the control configuration of the robotic vacuum cleaner base station 100 of the present invention.

[0429] The robot vacuum cleaner base station 100 of this embodiment of the invention also includes a control unit 300 comprising a control placement unit 120, a dust collection motor 145, a cloth washing unit 160, and a cloth drying unit 170.

[0430] The control unit 300 may consist of a printed circuit board and a plurality of components mounted on the printed circuit board.

[0432] The control unit 300 can sense the approach of the robotic vacuum cleaner 200 and control the door drive unit 134 to rotate the door 131. Specifically, the control unit 300 can sense whether the robotic vacuum cleaner 200 has entered via the entry sensor 135. If the distance between the robotic vacuum cleaner 200 and the door 131 is closer than a preset distance, the control unit 300 can rotate the door 131 to open the entrance 127. Alternatively, if the robotic vacuum cleaner 200 is attached to the mounting unit 120, the control unit 300 can rotate the door 131 to close the entrance 127.

[0433] If power is supplied to the battery of the robot vacuum cleaner 200 from the power supply terminal 123b, the control unit 300 can determine that the robot vacuum cleaner 200 has been attached to the mounting unit 120.

[0434] The control unit 400 can open the dust bin door 222 of the robotic vacuum cleaner 200. The control unit 300 can drive the dust collection motor 145 to suck up the dust inside the dust bin 220 of the robotic vacuum cleaner 200.

Evolution-Advanced (Long Term Evolution Enhanced), Wireless Mobile Broadband Service (WMBS), BLE (Bluetooth Low Energy), Zigbee, RF (Radio Frequency), LoRa (Long Range), etc.

[0439] The control unit 300 can control the cloth washing unit 160.

[0440] Specifically, the control unit 300 can control the detergent pump 163b. The control unit 300 can operate the detergent pump 163b to dispense detergent stored in the detergent box 163 to the rag 242.

[0441] Additionally, the control unit 300 can control the regulator 161. The control unit 300 can adjust the amount of clean water dispensed onto the wiping cloth 242 by operating the regulator 161.

[0442] Additionally, the control unit 300 can control the drain pump 168. The control unit 300 can discharge the wastewater after washing the rags 242 by operating the drain pump 168.

[0443] The control unit 300 can control the cloth drying unit 170.

[0444] Specifically, the control unit 300 can control the heater 174. The control unit 300 can heat the air expelled towards the rag 242 by operating the heater 174.

[0445] Additionally, the control unit 300 can control the air supply fan 175. The control unit 300 can expel air to the cloth 242 by operating the air supply fan 175.

[0446] The control unit 300 can control the air exhaust unit 180.

[0447] Additionally, the control unit 300 can control the exhaust fan 183. The control unit 300 can exhaust the air after drying the cloth 242 to the outside by operating the exhaust fan 183.

[0448] Additionally, the control unit 300 can receive signals from the temperature sensor 176. The control unit 300 can measure the temperature of the air inside the enclosure 110 using the temperature information received from the temperature sensor 176. Furthermore, the control unit 300 can control the operation of the heater 174 based on the temperature information received from the temperature sensor 176, thereby enabling the sterilization of bacteria present on the cloth 242.

[0449] The control unit 400 can move the rotating plate 241 of the robotic vacuum cleaner 200 downwards. The control unit 400 can also rotate the rotating plate 241.

[0450] The control unit 400 can control the steam supply unit 169.

[0451] The control unit 400 can supply water to the interior of the steam supply unit 169 and heat the water to a temperature of 55 degrees Celsius or higher but lower than 70 degrees Celsius. Alternatively, the control unit 400 can heat the water inside the steam supply unit 169 to a temperature of 100 degrees Celsius or higher. In addition, the control unit 400 can discharge water or wet steam from the steam supply unit 169 into the containing space S.

[0452] The control unit 400 can receive humidity information inside the robot vacuum base station 100 from the humidity sensor 177. Furthermore, the control unit 300 can adjust the internal humidity by controlling the exhaust fan 183, the blower fan 175, or the door drive unit 134 based on the humidity information received from the humidity sensor 177.

[0453] Control methods

[0454] Figures 17 to 19 A flowchart illustrating a control method for a robotic vacuum cleaner base station according to an embodiment of the present invention is shown. Figure 20 A flowchart illustrating a control method for a robotic vacuum cleaner base station according to another embodiment of the present invention is shown. Figure 21 The diagram illustrates the operation of the steam supply unit, heater, blower fan, and exhaust fan, which change over time, in a control method for a robot vacuum cleaner base station according to an embodiment of the present invention.

[0455] Below, refer to Figures 17 to 21 The control method of the sweeping robot base station 100 of the present invention will be described.

[0456] First, the control method of the sweeping robot base station of the present invention may include a dust collection step S120.

[0457] Specifically, in the dust collection step S120, if it is confirmed that the sweeping robot 200 is connected to the sweeping robot base station 100, the operation of emptying the dust bin 220 of the sweeping robot 200 can be performed.

[0458] The control unit 400 can confirm whether the sweeping robot 200 has been placed in the placement unit 120 by receiving signals generated by the sensor 125.

[0459] On the other hand, the control unit 400 can confirm whether the robot vacuum cleaner 200 is connected to the correct position by whether the charging unit supplies power to the battery of the robot vacuum cleaner 200.

[0460] Therefore, the control unit 400 can confirm whether the robot vacuum cleaner 200 has been placed in the placement unit 120 of the vacuum cleaner base station 100 by receiving a signal from the docking sensor 125 indicating that the robot vacuum cleaner 200 has docked and by confirming whether power is supplied to the battery through the charging unit.

[0461] In the dust collection step S120, if the robot vacuum 200 is placed at the robot vacuum base station 100, the dust bin door 222 of the robot vacuum 200 can be opened. If the dust bin door 222 is open, the dust inside the dust bin 220 can be collected by driving the dust collection motor 145.

[0462] Specifically, if a signal is received from the first cover opening sensing unit 155fa that the dust bin door 222 has been opened, the control unit 400 can make the dust collection motor 145 operate.

[0463] According to the dust collection step S120, the dust inside the dust bin 220 can be collected into the dust collection section 140 through the dust through-hole 123a and the dust collection flow paths 147 and 148. Therefore, even without additional user operation, the dust inside the dust bin 220 can be removed, thereby improving user convenience.

[0464] The control method of the sweeping robot base station of the present invention may include a cloth cleaning step S10, a sterilization cleaning step S20, and a cloth drying step S30.

[0465] In the cloth cleaning step S10, the cloth 242 can be cleaned by supplying washing water to the cloth 242 of the robot vacuum cleaner 200.

[0466] Specifically, if a signal is generated indicating that the dust collection step S120 has ended, the control unit 400 can begin the cloth washing step S10. The control unit 400 can supply washing water by activating the washing water supply unit.

[0467] The washing water supply unit can be configured to spray washing water directly onto the cloth 242 or onto the washing plate 122 such that the washing water is transferred when the cloth 242 comes into contact with the washing plate 122.

[0468] Additionally, if the start of the cloth cleaning step S10 is detected, the control unit 400 can move the rotating plate 241 of the robot vacuum cleaner 200 downwards. The rotating plate 241 can be configured to be able to move up and down, and can be configured such that at least a portion of the cloth 242 attached to the lower side of the rotating plate 241 contacts the cleaning plate 122 when it moves downwards.

[0469] Then, the control unit 400 can rotate the rotating plate 241. At this time, since the wiping cloth 242 rotates while in contact with the cleaning plate 122, it can be cleaned by friction.

[0470] In the sterilization and cleaning step S20, the cloth 242 can be sterilized by expelling heated water or wet steam into the cloth 242.

[0471] The sterilization and cleaning step S20 may include a sterilization and cleaning start step S210, an exhaust fan operation step S220, and a sterilization and cleaning end step S230.

[0472] In the sterilization cleaning start step S210, if the cloth cleaning step S10 has ended, the sterilization cleaning step S20 can be executed. Specifically, if a signal is received that the cloth cleaning step S10 has ended, the control unit 400 can execute the sterilization cleaning step S20.

[0473] The control unit 400 can heat water to a temperature above 55 degrees Celsius and below 70 degrees Celsius after supplying water to the steam supply unit 169. If the water is heated within the set temperature range, the control unit 400 can dispense the heated water into the rag 242.

[0474] Alternatively, the control unit 400 can operate the steam supply unit 169 to heat the water inside the steam supply unit 169 to a high temperature of 100 degrees Celsius or higher. If the water is heated to form steam, the control unit 400 can discharge the generated steam toward the rag 242.

[0475] On the other hand, depending on the situation, the control unit 400 can also operate by first emitting heated water for a specified period of time and then emitting steam. For example, it can operate by first spraying water heated to a temperature of 55 degrees or higher but lower than 70 degrees onto the cloth 242 to make the contaminants swell, and then continuously emitting steam at a temperature of 100 degrees or higher to remove the remaining contaminants and improve the sterilization effect.

[0476] This method can be automatically set by the control unit 400 according to the soiling status or cleaning mode of the cloth 242, or the user can select it directly as needed.

[0477] Therefore, it can effectively remove contaminants attached to the cloth 242, and reduce bacteria and harmful microorganisms through the sterilization effect based on high-temperature steam, thereby achieving hygienic cleaning.

[0478] In the exhaust fan operation step S220, the control unit 400 can operate the exhaust fan 183. Specifically, during the sterilization and cleaning step S20, the control unit 400 can exhaust internal air by operating the exhaust fan 183.

[0479] As an example, if a signal is received that the cloth cleaning step S10 has ended, the control unit 400 can activate the exhaust fan 183. Thus, the exhaust fan 183 can operate in conjunction with the sterilization cleaning step S20.

[0480] As another example, during the sterilization and cleaning step S20, the control unit 400 can confirm the internal humidity information of the robot vacuum base station 100 from the humidity sensor 177. At this time, if the measured internal humidity is above 70%, the control unit 400 can exhaust the internal air by running the exhaust fan 183.

[0481] Conversely, if the internal humidity is below the specified value, the sterilization and cleaning step S20 can continue without operating the exhaust fan 183.

[0482] On the other hand, the sterilization and cleaning step S20 of the control method for the robot vacuum cleaner base station of an embodiment of the present invention may also include a humidity confirmation step S221 and a fan operation step S222.

[0483] In the humidity confirmation step S221, the control unit 400 can confirm the internal humidity by receiving a signal from the humidity sensor 177. Specifically, if the control unit 400 receives a signal from the humidity sensor 177 that the internal humidity of the robot vacuum base station 100 is above a predetermined value, it can determine that external air needs to flow in.

[0484] For example, if the measured internal humidity is above 70%, it can be determined that the humidity is high, and the next step, namely the operation of the air supply fan, can be performed. Conversely, if the internal humidity is below a preset baseline value, the operation of the air supply fan, S222, can be omitted. In this case, the sterilization and cleaning end step, S230, can be performed after a preset sterilization and cleaning time, tS20.

[0485] In step S222, the control unit 400 can operate the air blower 175 based on the result of step S221, whereby the humidity confirmation unit S221 determines whether the air blower 175 is operating. Specifically, upon receiving a signal that the internal humidity is 70% or higher, the control unit 400 can operate the air blower 175 to allow external air to flow into the robot vacuum base station 100. This promotes internal air circulation and thus removes moisture.

[0486] The exhaust fan 183 and the blower fan 175 can operate simultaneously or separately depending on the internal humidity level, thereby maintaining a hygienic state by removing moisture from the inside of the robot vacuum base station 100 and inhibiting the growth of mold and bacteria.

[0487] On the other hand, according to another embodiment of the present invention, the door opening step S222' can be performed after the humidity confirmation step S221.

[0488] In the humidity confirmation step S221, the control unit 400 can confirm the humidity status by receiving internal humidity information from the humidity sensor 177. Specifically, if a signal is received from the humidity sensor 177 indicating that the internal humidity is above a predetermined value, the control unit 400 can determine that internal air needs to flow in and proceed to the next step, namely the door opening step S222'.

[0489] In the door opening step S222', the control unit 400 can open the door 131 based on the result of the humidity confirmation step S221. For example, if the humidity sensor 177 receives a signal that the internal humidity is 70% or higher, the control unit 400 can open the door 131 by driving the door drive unit 134. If the door 131 is open, outside air can flow into the interior of the robot vacuum base station 100. Conversely, if the internal humidity is lower than a preset reference value, the door opening step S222' can be skipped. In this case, if the preset sterilization cleaning time tS20 has elapsed, the sterilization cleaning end step S230 can be performed.

[0490] On the other hand, the opening of door 131 can be performed in conjunction with the operation of the air supply fan 175 in order to allow the inflow of outside air.

[0491] In the sterilization and cleaning completion step S230, if the control unit 400 determines that a preset sterilization and cleaning time tS20 has elapsed, then the control unit 400 can determine that the sterilization and cleaning step S20 has ended. The sterilization and cleaning time tS20 can depend on a time preset by the user. Alternatively, an appropriate time can be pre-input into the control unit 400. At this time, the control unit 400 can stop the steam supply unit 169 and end the sterilization and cleaning step S20 (S230).

[0492] In the cloth drying step S30, the cloth can be dried by running the fan 175 that blows air into the cloth 242 of the robot vacuum cleaner 200.

[0493] The cloth drying step S30 may include a cloth drying start step S310, a fan and heater operation step S320, an exhaust fan, fan and heater stop step S330, and a cloth drying end step S340.

[0494] In the cloth drying start step S310, if a signal indicating that the sterilization and cleaning step S20 has ended is received, the control unit 400 can start the cloth drying step. Afterwards, the next step can be performed, executing the fan and heater operation step S320.

[0495] In step S320, when the blower and heater are in operation, the control unit 400 can operate the blower 175. On the other hand, if the blower 175 is already in operation in step S20, depending on the humidity conditions, the control unit 400 can maintain the operation of the blower 175.

[0496] Additionally, the control unit 400 can operate the heater 174. As a result, the air heated by the heater 174 can be expelled to the cloth 242 by the blower fan 175.

[0497] On the other hand, the control unit 400 can operate the exhaust fan 183. When the exhaust fan 183 is already running, the control unit 400 can keep the exhaust fan 183 running.

[0498] In another embodiment of the present invention, the control method of the robot vacuum cleaner base station may further include a cloth drying step S30, which may include a humidity confirmation step S321 and a door closing step S322.

[0499] In humidity confirmation step S321, the control unit 400 can receive internal humidity information from the humidity sensor 177 to confirm the humidity. Specifically, if a signal indicating that the internal humidity is lower than a predetermined value is received, the control unit 400 can determine that the inflow of external air is unnecessary and proceed to the next step, namely the door closing step S322. For example, if the internal humidity is measured to be lower than 35%, the control unit 400 can execute the door closing step S322.

[0500] In the door closing step S322, the control unit 400 can close the door 131 based on the result of the humidity confirmation step S321. Specifically, if a signal is received from the humidity sensor 177 indicating that the internal humidity is below 35%, the control unit 400 can close the door 131 by driving the door drive unit 134. Thus, when the internal humidity is kept below a specified level, the internal environment can be stably maintained by blocking unnecessary external air inflow.

[0501] Conversely, if the internal humidity is above a preset baseline value, the door closing step S322 can be omitted. In this case, if the preset cloth drying time tS30 has elapsed, the next step, namely the exhaust fan, blower fan, and heater stopping step S330, can be performed.

[0502] In the step S330 of stopping the exhaust fan, blower fan, and heater, if it is determined that the predetermined drying time tS30 has elapsed, the control unit 400 may interrupt the operation of the components used in the cloth drying process. Specifically, the control unit 400 may stop the heater 174. The control unit 400 may stop the exhaust fan 183.

[0503] The control unit 400 can stop the air supply fan 175. On the other hand, if the air supply fan 175 is in a stopped state during the sterilization and cleaning step S20 according to the humidity conditions, the control unit 400 can maintain the stopped state of the air supply fan 175.

[0504] In another embodiment of the control method for the robot vacuum cleaner base station, if it is determined that the cloth drying time tS30 has elapsed, the control unit 400 may close the door 131. At this time, if the door 131 is already in a closed state, the control unit 400 may maintain the closed state.

[0505] In the cloth drying end step S340, the control unit 400 can end the cloth drying step S30 after a predetermined time has elapsed. The cloth drying time tS30 can be determined according to a value preset by the user, or it can be set as a predetermined time on the system. The cloth drying step S30 can end after the set time has elapsed.

[0506] Alternatively, the control unit 400 can measure the humidity of the cloth and end the cloth drying step S30 when the humidity decreases to below a specified reference value.

[0507] Below, refer to Figure 21 The operating sequence of the steam supply unit 169, heater 174, air supply fan 175 and exhaust fan 183 in the control method of the sweeping robot base station according to an embodiment of the present invention will be described.

[0508] In the sterilization and cleaning step S20, the control unit 400 can heat water by operating the steam supply unit 169 and then discharge heated water or steam to the cloth 242. At this time, the control unit 400 can maintain the operation of the steam supply unit 169 for a predetermined time, and then interrupt the operation of the steam supply unit 169 when the set temperature or time condition is met. The operating time of the steam supply unit 169 can be shorter than the sterilization and cleaning time tS20.

[0509] If the sterilization and cleaning step S20 begins, the exhaust fan 183 can be operated to remove wet steam. If the sterilization and cleaning step S20 begins, the air supply fan 175 can be operated to allow outside air to flow in. The control unit 400 can keep the exhaust fan 183 or the air supply fan 175 running during the sterilization and cleaning time tS20.

[0510] Conversely, although not shown, the operation of the exhaust fan 183 and the air supply fan 175 can be adjusted according to humidity conditions. For example, during the execution of the sterilization and cleaning step S20, the control unit 400 can receive internal humidity information from the humidity sensor 177 and determine whether to operate the exhaust fan 183 and the air supply fan 175 based on this information. If the internal humidity rises above a predetermined value, the control unit 400 can operate the exhaust fan 183 and the air supply fan 175 to expel moisture to the outside and circulate internal air. Conversely, if the internal humidity is lower than a set reference value, the operation of the exhaust fan 183 or the air supply fan 175 can be interrupted, or the system can operate by only driving the air supply fan 175 to adjust the inflow of external air.

[0511] In the cloth drying step S30, the control unit 400 can generate heated air by operating the heater 174. The generated heated air can then be expelled towards the cloth 242 by the blower fan 175. During this process, the exhaust fan 183 can regulate the internal humidity by expelling internal air to the outside. The control unit 400 can maintain the operation of the heater 174, the exhaust fan 183, or the blower fan 175 during the cloth drying time tS30.

[0512] As another example, the heater 174 can be controlled to repeatedly turn on and off at predetermined intervals during the cloth drying time tS30, rather than operating continuously. If a predetermined time has elapsed after the cloth drying has started, the control unit 400 can stop the heater 174, and then restart the heater 174 after another predetermined time has elapsed. The heater can be turned on and off repeatedly in this manner 2 to 3 times.

[0513] This method not only prevents excessive heat generation but also effectively maintains the drying effect.

[0514] The present invention has been described in detail above through specific embodiments, but this is only for the purpose of illustrating the present invention. The present invention is not limited thereto. Obviously, the present invention can be modified or altered by those skilled in the art within the scope of the technical concept of the present invention.

[0515] Simple variations or modifications of this invention are all within the scope of this invention, and the specific scope of protection of this invention will become clearer through the scope of the claims.
