Description

Technical Field

[0001] This invention relates to a sweeping robot and a sweeping robot system, and more specifically, to a sweeping robot and a sweeping robot system that, when combined with a sweeping robot, can collect dust from the sweeping robot's dustbin, clean the sweeping robot's mop, and dry the mop. Background Technology

[0002] In recent years, with the development of industrial technology, a type of sweeping robot has been developed that can autonomously drive and clean the area that needs 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 efficiency of indoor space. In addition, collisions with the robot vacuum may occur when users or pets pass by, resulting in injuries to the users or pets 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, a hot air module for drying the mop cloth of the robot vacuum cleaner can be installed at the robot vacuum cleaner base station.

[0009] Relatedly, Chinese utility model CN217090594U discloses a base station that uses hot air flow to dry a wet rag attached to the rag plate of a sweeping robot.

[0010] The base station is provided with air vents to expel air from the ribs formed on the cleaning plate.

[0011] However, as mentioned above, when hot air is emitted from only a portion of the washing plate, there is a limitation that the hot air cannot be supplied evenly to the wet cloth. Therefore, more drying time is required to completely dry the cloth, resulting in reduced energy efficiency.

[0012] In addition, if the cloth is dried for an extended period of time in order to dry the entire cloth, certain parts may become over-dried, which could damage the cloth. Summary of the Invention

[0013] The present invention is proposed to improve the problems existing in the above-mentioned existing sweeping robots and sweeping robot systems. Its purpose is to provide a sweeping robot system that can automatically clean and dry the sweeping robot's mop.

[0014] In addition, the aim is to provide a robotic vacuum cleaner system that can improve the efficiency of energy and time required to dry the mop cloth of the robotic vacuum cleaner.

[0015] In addition, the purpose is to provide a robotic vacuum cleaner system that can prevent the mop cloth of the robotic vacuum cleaner from being dried unevenly.

[0016] To achieve the objectives described above, the sweeping robot system of the present invention may include: a sweeping robot comprising a main body, a rotating plate, and a mop, wherein the rotating plate is rotatably coupled to the lower side of the main body, and the mop is detachably coupled to the rotating plate; and a sweeping robot base station comprising a cover, a mounting section, a mop washing section, and a mop drying section, wherein the mounting section is disposed within the cover and includes a washing plate, the sweeping robot is mounted on the washing plate, the mop washing section washes the mop of the sweeping robot, and the mop drying section dries the mop of the sweeping robot; the rotating plate rotates during the operation of the mop drying section.

[0017] At this time, the rotating plate can rise during the operation of the cloth drying section.

[0018] On the other hand, the cloth drying section may include: an external air inlet for air from outside the cover to flow in; a heater for heating the air flowing in through the external air inlet; and an external air outlet for discharging the air heated by the heater to the cloth; the rotating plate rotates during the operation of the heater.

[0019] The cloth drying unit may also include a blower fan, which provides flow force to the air flowing in through the external air inlet, and the rotating plate rotates during the operation of the blower fan.

[0020] In addition, the cloth drying unit may also include an exhaust fan that provides flow force to the air flowing in through the air intake, and the rotating plate rotates during the operation of the exhaust fan.

[0021] On the other hand, the robot vacuum cleaner base station may also include a humidity sensor for measuring humidity; the mop drying unit further includes: an air intake port disposed inside the cover to draw in air from inside the cover; and an air exhaust pipe for airflow through the air intake port; the humidity sensor is disposed in the air exhaust pipe.

[0022] If the rate of change of humidity measured by the humidity sensor is below a preset reference value, the rotating plate can stop rotating.

[0023] On the other hand, in the robot vacuum cleaner base station, after the cloth washing unit operates, the cloth drying unit can operate, and the rotating plate can rotate during the operation of the cloth washing unit.

[0024] At this time, the height of the rotating plate during the operation of the cloth drying section can be higher than the height of the rotating plate during the operation of the cloth washing section.

[0025] In addition, the robot vacuum cleaner base station may also include a turbidity sensor for measuring the turbidity of the liquid. If the turbidity measured by the turbidity sensor is above a preset reference value, the rotation time of the rotating plate is increased.

[0026] At this time, the rag cleaning unit may include a regulator that regulates the flow rate of liquid supplied from the water supply pipe, and the rotating plate rotates during the operation of the regulator.

[0027] The rag can be located on the upper side of the cleaning plate of the robot vacuum base station and rotates as heated air flows in.

[0028] If heated air flows in, the cloth can rise and move.

[0029] As described above, the sweeping robot system according to the present invention has the effect of evenly drying the entire mop cloth by rotating the rotating plate when drying the mop cloth of the sweeping robot.

[0030] In addition, the rotating plate is rotated in a downward state when washing the cloth, and in an upward state when drying the cloth, which can improve the efficiency of washing and drying.

[0031] In addition, by rotating the mop 180 degrees at a predetermined interval, it can evenly dry the mop of the robot vacuum cleaner.

[0032] In addition, it has the effect of preventing problems such as microbial growth caused by parts of the cloth not being completely dried.

[0033] In addition, by shortening the time required to completely dry the cloth, it has the effect of improving energy efficiency. Attached Figure Description

[0081] This invention can be modified in various ways and can have various embodiments; therefore, specific embodiments are intended to be shown in the accompanying drawings and described in detail in the accompanying description. This is not intended to limit the invention to the specific implementations, but should be interpreted as encompassing all modifications, equivalents, and substitutions included within the spirit and scope of the invention.

[0089] Kitchen cabinets and robot vacuum systems

[0090] Figure 1 A diagram is shown illustrating the state in which a robotic vacuum cleaner system according to an embodiment of the present invention is installed on the underside of a kitchen cabinet. Figure 2 A diagram illustrating the relationship between the piping and drainage pipe connections of the sweeping robot system according to an embodiment of the present invention is shown.

[0091] Reference Figure 1 and Figure 2 The robotic vacuum cleaner system 1 of this invention 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.

[0092] In addition, kitchen cabinet 2 can be equipped with an upper panel (workbench) that can function as a sink, cooking table, or work surface.

[0093] 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.

[0094] 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.

[0095] In another embodiment of the present invention, a robotic vacuum cleaner 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 supplying fluid to the structure, and the drain pipe can refer to a flow path that discharges fluid from the structure into a sewer.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] The robotic vacuum cleaner system 1 of this invention can be installed in the space between the kitchen floor and the lower side panel 23 as described above (hereinafter referred to as the installation space).

[0100] For example, the installation space can be less than 200mm in height, and typically can be less than 160mm in height.

[0101] Therefore, according to the present invention, the robotic vacuum cleaner system 1 is disposed in the lower space of the kitchen cabinet 2, thus having the effect of minimizing the amount of the robotic vacuum cleaner system 1 exposed to the outside.

[0102] 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 robot vacuum cleaner system 1 in the unused space created by the kitchen cabinet 2 does not occupy additional space, thus maximizing space efficiency.

[0103] 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.

[0104] The sweeping robot system 1 of this invention can use the drain pipe 25 as described above to clean and dry the mop 242 of the sweeping robot 200.

[0105] Additionally, although not shown, a water supply pipe may be installed in the kitchen cabinet 2. Tap water (or purified water) can be supplied to the robot vacuum system 1 through the water supply pipe.

[0106] The following describes the specific structure of the robotic vacuum cleaner system 1.

[0107] Robotic vacuum cleaner system

[0108] on the other hand, Figure 3 and Figure 4 A diagram is shown illustrating a robotic vacuum cleaner system according to an embodiment of the present invention.

[0109] The robotic vacuum cleaner system 1 in the embodiments of this specification may include a robotic vacuum cleaner base station 100 and a robotic vacuum cleaner 200.

[0110] The robotic vacuum cleaner system 1 includes a robotic vacuum cleaner base station 100. A robotic vacuum cleaner 200 can be integrated into the robotic vacuum cleaner base station 100. Specifically, the robotic vacuum cleaner 200 can enter from the front of the robotic vacuum cleaner base station 100 and can be housed inside the robotic vacuum cleaner base station 100. The robotic vacuum cleaner base station 100 can remove dust from the dustbin 220 of the robotic vacuum cleaner 200. The robotic vacuum cleaner base station 100 can clean the rotating cleaning section 240 of the robotic vacuum cleaner 200. The robotic vacuum cleaner base station 100 can dry the rotating cleaning section 240 of the robotic vacuum cleaner 200. The robotic vacuum cleaner base station 100 can supply power to the robotic vacuum cleaner 200.

[0111] robot vacuum cleaner

[0112] on the other hand, Figures 5 to 9bA diagram illustrating a sweeping robot system according to an embodiment of the present invention is provided.

[0113] Reference Figures 5 to 9b This explains the structure of the 200 robotic vacuum cleaner.

[0114] 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.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] The sweeping robot 200 of this invention includes a main body 210, a dust bin 220, a water bin 230, a rotating cleaning unit 240, an agitator 250, wheels 260, auxiliary wheels 270, and a charging terminal 280.

[0119] 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.

[0120] 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.

[0121] 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).

[0122] When viewed from above or below, the main body 210 can be formed into various shapes such as circles, ovals, or quadrilaterals.

[0123] 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.

[0124] 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.

[0125] The lower body may have an intake section 211 for air to flow in and a hole for accommodating a pair of wheels 260.

[0126] 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.

[0127] 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.

[0128] 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.

[0129] 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.

[0130] 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.

[0131] The robotic vacuum cleaner 200 of the present invention may include a bumper. The bumper is attached along the edge of the main body 210 and is movable relative to the main body 210.

[0132] 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.

[0133] The dust bin 220 can suck in external dust and air to store dust.

[0134] 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.

[0135] 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 of course, it can be separated according to the embodiment.

[0136] 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.

[0137] 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.

[0138] 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.

[0139] 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.

[0140] 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.

[0141] 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.

[0142] 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.

[0143] 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.

[0144] 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.

[0145] 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.

[0146] 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.

[0147] The rotating cleaning unit 240 includes a rotating plate 241 and a cleaning cloth 242.

[0148] 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.

[0149] 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.

[0150] 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.

[0151] A pair of rotating plates 241 can achieve left-right symmetry.

[0152] The rag 242 can be attached to the underside of the rotating plate 241 to face the floor surface.

[0153] 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.

[0154] 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.

[0155] On the other hand, 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 include a rotating plate motor 243, a rotating plate gear 244, and a rotating plate shaft 245. Therefore, when the drive unit is running, the rotating plate 241 and the mop 242 can rotate and wipe the floor surface.

[0156] On the other hand, in this embodiment, the rotating plate 241 can be configured to have an adjustable height. Specifically, the rotating plate motor 243 can be configured to change the direction of rotation. Thus, if the rotating plate motor 243 rotates in a predetermined direction, the rotating plate 241 can descend, and if the rotating plate motor 243 rotates in the opposite direction, the rotating plate 241 can rise.

[0157] The rotating plate gear section 244 can transmit the rotational force of the rotating plate motor 243 to the rotating plate shaft 245.

[0158] The rotary plate gear section 244 can be configured to include a plurality of gears. For example, the rotary plate gear section 244 may include a turbine that is coupled to and rotates together with the shaft of the rotary plate motor 243, a connecting gear that meshes with and rotates in conjunction with the turbine, and a driven gear that meshes with and rotates with the connecting gear. In this case, a gear is formed on the upper outer peripheral surface of the driven gear, which meshes with the connecting gear, and an external thread may be formed on its lower outer peripheral surface.

[0159] Furthermore, the rotating plate shaft 245 is formed in a cylindrical shape, and at least a portion of the driven gear can be accommodated inside. Additionally, an external thread can be formed on the inner circumferential surface of the rotating plate shaft 245. In this case, the external thread formed on the driven gear can rotate relative to the inner circumferential surface of the rotating plate shaft 245, and can move relative to the external thread formed on the inner circumferential surface of the shaft 245.

[0160] Therefore, if the rotary plate motor 243 rotates in a predetermined direction, the driven gear rotates in that direction, thereby allowing the rotary plate shaft 245 to move downwards. Furthermore, after the driven gear moves to the upper inner end of the rotary plate shaft 245, the driven gear and the rotary plate shaft 245 can rotate together. That is, if the rotary plate motor 243 rotates in one direction, the rotary plate 241 can rotate after its downward movement.

[0161] Conversely, if the rotary plate motor 243 rotates in the opposite direction, the driven gear rotates in the opposite direction, thereby allowing the rotary plate shaft 245 to move upward. Furthermore, after the driven gear moves to the lower inner end of the rotary plate shaft 245, the driven gear and the rotary plate shaft 245 can rotate together. That is, if the rotary plate motor 243 rotates in the opposite direction, the rotary plate 241 can rotate after its upward movement.

[0162] 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.

[0163] 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.

[0164] 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.

[0165] Wheel 260 can be installed on the main body 210 and can roll on the floor surface.

[0166] 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.

[0167] 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.

[0168] 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.

[0169] 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.

[0170] 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.

[0171] 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.

[0172] 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).

[0173] In addition, the battery can supply power to the sensor unit (not shown) and the control unit (not shown).

[0174] 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.

[0175] Robot vacuum cleaner base station

[0176] Reference Figures 3 to 16 This describes the robot vacuum cleaner base station 100 of the present invention.

[0177] 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.

[0178] The robot vacuum cleaner base station 100 may include a cover 110.

[0179] 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.

[0180] The interior of the cover 110 can be formed with a space that can accommodate the placement section 120, the door section 130, the dust collection section 140, the cloth washing section 160, and the cloth drying section 170.

[0181] 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.

[0182] The enclosure 110 includes a pair of outer walls 111 facing each other. The outer walls 111 may refer to the surfaces formed along the direction of gravity.

[0183] As an example, a pair of outer walls 111 can be arranged at predetermined intervals on the lower side of the kitchen cabinet 2. In this case, the cover 110 also includes a bottom surface 112 facing the kitchen floor, through which the pair of outer walls 111 can be connected. 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 the 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 contamination of the components of the robot vacuum 200 and the robot vacuum base station 100. Additionally, the cover 110 may also include a rear surface 115 facing the wall of the building. With this configuration, the components of the robot vacuum base station 100 can be accommodated inside the cover 110 (between the pair of outer walls).

[0184] 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.

[0185] 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.

[0186] 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.

[0187] In addition, based on the observation of the front from inside the robot vacuum cleaner base station 100, the left side can be called the left side and the right side can be called the right side.

[0188] That is, the outer wall 111 of the robot vacuum cleaner base station 100 can be configured on the left side and the right side respectively.

[0189] 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.

[0190] This minimizes the amount of the robot vacuum base station 100 and the robot vacuum 200 exposed to the outside.

[0191] 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.

[0192] layout

[0193] 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.

[0194] Therefore, the robot vacuum 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.

[0195] 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.

[0196] 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.

[0197] 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.

[0198] 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.

[0199] In the sweeping robot base station 100 of this embodiment, the dust collection unit 140, the cloth washing unit 160, and the cloth drying unit 170 can all be configured within a specified distance range of the outer contour of the placement unit 120.

[0200] 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 extent of washing water and wastewater remains is limited.

[0201] 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.

[0202] 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.

[0203] Resettlement Department

[0204] like Figure 13 and Figure 16 As shown, the robot vacuum cleaner base station 100 may include a mounting unit 120.

[0205] 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.

[0206] The mounting section 120 can be installed inside the cover 110.

[0207] 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.

[0208] The entrance / exit 127 can be configured to allow the robotic vacuum cleaner 200 to pass through. That is, the height of the entrance / exit 127 is configured to be greater than the height of the robotic vacuum cleaner 200.

[0209] 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. Therefore, 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.

[0210] At this time, entrance / exit 127 can be opened and closed by door 131.

[0211] The placement part 120 may include a receiving space S, a base 121, a connecting wall 123, and an inner wall 124.

[0212] The robotic vacuum cleaner 200 can be housed in the housing space S of the placement section 120. As an example, the housing space S can refer to the space surrounded by the base 121, the connecting wall 123, and the inner wall 124. As another example, the housing space S can refer to the space surrounded by the base 121, the cleaning plate 122, the connecting wall 123, and the inner wall 124.

[0213] 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.

[0214] 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.

[0215] 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.

[0216] The base body 121a can be formed such that its length and width in the horizontal direction are greater than its height in the vertical direction. Due to this structure, the robot vacuum cleaner base station 100 can be stably supported on the bottom surface.

[0217] 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 formed inside the base body 121a and be discharged to the air return port 125b.

[0218] The inclined part 121b can be configured in the bottom component body 121a as an entry point for the sweeping robot 200 to climb.

[0219] The tilting part 121b may have a forward tilt in the direction in which the robot vacuum cleaner 200 enters.

[0220] A wheel guide 121ba may be provided in the inclined section 121b.

[0221] The wheel guide 121ba can be formed into a groove shape to guide the movement of the wheels 260 of the sweeping robot 200.

[0222] An auxiliary wheel guide 121bb may be provided in the inclined section 121b.

[0223] The auxiliary wheel guide 121bb can be formed in a groove shape to guide the movement of the auxiliary wheel 270 of the robotic vacuum cleaner 200. Alternatively, the auxiliary wheel guide 121bb can be formed in a protruding shape so that when the wheel 260 of the robotic vacuum cleaner 200 is placed on the wheel guide 121ba, it connects with the auxiliary wheel 270. Thus, when the robotic vacuum cleaner 200 travels on the inclined section 121b, the wheel 260 and the auxiliary wheel 270 can be stably supported and used for travel.

[0224] The wheel 260 of the sweeping robot 200, which moves upward along the wheel guide 121ba, can be installed in the wheel engagement portion 121c. If the wheel 260 of the sweeping robot 200 is installed in the wheel engagement portion 121c, the sweeping robot 200 and the sweeping robot base station 100 can be physically connected.

[0225] The shape of the wheel joint 121c can be formed into an arc shape that corresponds to the shape of the wheel 260 of the robot vacuum cleaner 200.

[0226] At least a portion of the agitator 250 of the robotic vacuum cleaner 200 can be accommodated in the agitator accommodating portion 121d.

[0227] The agitator receiving portion 121d can be formed between the wheel engagement portion 121c. The agitator receiving portion 121d can be formed in a shape corresponding to the agitator 250 of the sweeping robot 200. The agitator receiving portion 121d can be formed in a cuboid shape with an open upper part.

[0228] The agitator receiving portion 121d can be formed to be recessed from the base body 121a. Thus, with the wheels 260 of the sweeping robot 200 placed in the wheel engagement portion 121c, the agitator receiving portion 121d can provide space to accommodate the lower end of the agitator 250.

[0229] 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 recess 121da and the dust collection motor 145 through a return flow path. The recess 121da 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 through the air return port 125b to the recess 121da of the agitator housing 121d.

[0230] 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.

[0231] On the other hand, the base 121 can be configured to be extended from the cover 110 and the drawer 190. In this case, the base 121 can be extended through the inlet 127 along the space between the inner walls 124.

[0232] To facilitate extraction, a base handle 121e may be formed on the base 121. The base handle 121e may be formed between the agitator housing 121d and the auxiliary wheel guide 121bb. Alternatively, the base handle 121e may be formed between a pair of wheel guides 121ba.

[0233] With this configuration, the user can easily pull out the base 121 by pulling the handle 121e.

[0234] 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 outer contour 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.

[0235] A dust passage 123a can be formed in the mounting section 120 to allow air from outside the cover 110 to flow into the interior. Specifically, a dust passage 123a can be formed in the connecting wall 123 to allow air from outside the cover 110 to flow into the interior.

[0236] The dust outlet 123a can be connected to the dust bin 220 of the robot vacuum cleaner 200.

[0237] 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.

[0238] The robot vacuum cleaner base station 100 may also include a water supply nozzle 123c.

[0239] 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.

[0240] The inner wall 124 is a component that spatially divides the accommodating space S of the placement part 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.

[0241] On the other hand, various components such as dust collection paths 147 and 148, dust collection unit 140, dust collection motor 145, detergent tank 163, and wastewater tank 166 can be arranged on the outer side of the inner wall 124. Specifically, the dust collection unit 140, detergent tank 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.

[0242] The dust collection section 140 and the detergent tank 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 tank 163 can be made smaller than the distance between the inner wall 124 and the outer wall 111 of the cover 110.

[0243] 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.

[0244] The cleaning plate 122 can be a plate that is generally inclined downwards towards the center.

[0245] 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.

[0246] At this time, a pair of cleaning protrusions 122a can be symmetrically formed on the flow guide surface 122c.

[0247] Furthermore, a plurality of through holes 122b may be formed on the flow guide surface 122c, and may be formed between a pair of cleaning protrusions 122a.

[0248] On the other hand, as one approaches the location where the through-hole 122b is formed, the height of the flow guide surface 122c relative to the kitchen floor can increase. That is, as one approaches the external air exhaust portion 171c described later, the height of the flow guide surface 122c relative to the kitchen floor can increase.

[0249] 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.

[0250] If washing water is supplied to the washing plate 122 and the cloth 242 rotates, the cloth 242 can be rubbed against the stationary washing protrusion 122a and cleaned.

[0251] 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 is formed by protruding upward from the flow guide surface 122c and attached to the upper side of the flow path forming portion 128c.

[0252] 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 be formed by protruding upward from the flow guide surface 122c, covering the lower flow path forming portion 128c.

[0253] 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.

[0254] The cleaning tank 128 is configured to accommodate 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.

[0255] The cleaning tank 128 may include a cleaning tank base surface 128a for fluid flow through the cleaning plate 122 and a cleaning tank wall 128b extending vertically from the outer contour of the cleaning tank base surface 128a. At this time, as it approaches the rear of the robotic vacuum cleaner base station 100, the height of the cleaning tank base surface 128a from the ground (kitchen floor) can decrease. Therefore, the fluid flowing through the cleaning plate 122 can be collected at the rear of the cleaning tank 128 and discharged to the outside through the wastewater inlet 164c, described later.

[0256] At this point, in order to connect with the sewage inlet 164c, a sewage pipe connection port 128d can be formed on the cleaning tank wall 126b.

[0257] 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 and forming a return flow path 125a on the lower side.

[0258] On the other hand, the cleaning tank 128 of the present invention can 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.

[0259] Door

[0260] Figures 10 to 12 A diagram is shown to illustrate the door section 130.

[0261] Door 130 can be configured to cover the entire front end of cover 110. Door 131 is capable of covering dust bag drawer 144 and detergent container 163 so that they are not exposed to the outside.

[0262] When the entrance / exit 127 is closed, the door 131 can form the front appearance of the robot vacuum base station 100. For example, the door 131 can be formed into a nearly rectangular flat shape.

[0263] 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 container insertion port 132b, to which a detergent container 163 is connected.

[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 ground 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] In addition, the door 131 may have an auxiliary entry channel 131b on the side facing the enclosure 110 when the entrance / exit 127 is closed.

[0267] Specifically, to ensure stable tilting movement of the robotic vacuum cleaner 200, the auxiliary entry channel 131b can be formed into a groove shape. 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 and right movement becomes, and they can be guided to the 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] 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).

[0270] 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.

[0271] 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.

[0272] A door operating part 133 is provided in the door frame 132, which can rotate the door 131 by the user's operation.

[0273] 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 robot vacuum cleaner 200.

[0274] 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.

[0275] At this time, the button can be configured adjacent to the detergent tank 163 with the inlet / outlet as the reference. For example, the button can be configured on the upper side of the handle 163b of the detergent tank 163.

[0276] 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.

[0277] Door 131 can be rotated via door drive unit 134. As an example, door drive unit 134 may include a door drive motor and a drive gear unit.

[0278] The door drive motor can be configured inside the housing 110 and in the upper space of the detergent tank 163.

[0279] 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.

[0280] Dust Collection Department

[0281] exist Figures 13 to 21 The diagram shows the dust collection section of a robotic vacuum cleaner base station used to illustrate an embodiment of the present invention.

[0282] Reference Figures 13 to 21 The dust collection unit 140 will be explained.

[0283] 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 housing 110. The dust collection unit 140 can also be disposed outside the mounting portion 120. For example, the dust collection unit 140 can be disposed on one side of the mounting portion 120 in the left-right direction.

[0284] 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.

[0285] The interior of the dust collection unit cover 141 can form a space that can accommodate the filter 142, the dust bag 143 and the dust bag drawer 144.

[0286] 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.

[0287] Dust inside the dust bin 220 can flow into the dust collection unit cover 141.

[0288] 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.

[0289] Specifically, the dust collection section cover 141 may have an inlet 141a communicating with the first dust collection flow path 147 and an outlet 141b communicating with the second dust collection flow path 148.

[0290] At this time, the inlet 141a can be positioned above the outlet 141b. Thus, air and dust flowing in through the inlet 141a flow downwards, and after the dust is captured by the dust bag 143, it can be discharged through the outlet 141b.

[0291] On the other hand, in this embodiment, the outlet 141b can be configured at a position further forward than the inlet 141a.

[0292] On the other hand, the discharge port 141b can be formed by combining the dust collection hood 141 with the dust bag drawer 144. In this case, the discharge port 141b of the dust collection hood 141 and the discharge port 144c of the dust bag drawer 144 can refer to the same space.

[0293] The dust bag drawer 144 includes a dust bag drawer body 144a, an inlet 144b, an outlet 144c, a handle 144d, and a flow path forming part 144e.

[0294] The dust bag drawer body 144a can provide internal space for accommodating the dust bag 143. For example, the dust bag drawer body 144a can be formed in the shape of a box with an open top, and an inlet 144b can be formed on the rear side to communicate with the first dust collection path 147. In this case, the inlet 144b can communicate with the inlet 141a of the dust collection unit cover 141.

[0295] The upper side of the dust bag drawer body 144a can be connected to the first dust collection path 147 via the inlet 144b. The inlet 144b can be configured to guide the air flowing in the first dust collection path 147 into the interior of the dust bag 143. The inlet 144b can connect the first dust collection path 147 and the dust bag 143. Therefore, dust sucked in from the dust bin 220 of the robotic vacuum cleaner 200 can move into the interior of the dust bag 143 via the first dust collection path 147, the inlet 141a of the dust collection cover 141, and the inlet 144b of the dust bag drawer 144.

[0296] The dust bag drawer 144 can be connected to the second dust collection path 148 through the discharge port 144c formed on the lower side (bottom).

[0297] At this time, the outlet 144c can be configured at a different height than the inlet 144b. The outlet 144c can be configured to be lower than the inlet 144b with the lower side (bottom) of the dust bag drawer 144 as a reference. The outlet 144c can communicate with the internal space of the dust bag drawer 144 and the second dust collection path 148. Therefore, air that has been filtered of dust while passing through the dust bag 143 can move to the second dust collection path 148 through the outlet 144c.

[0298] On the other hand, in this embodiment, the outlet 144c can be configured to be positioned further forward than the inlet 144b. For example, the outlet 144c can be configured to be closer to the handle 144d than the inlet 144b.

[0299] On the other hand, the dust bag drawer 144 forms a flow path for air passing through the dust bag 143 to be discharged to the dust collection motor 145. That is, the dust bag drawer 144 includes a flow path forming part 144e, which protrudes upward from the bottom surface of the dust bag drawer body 144a, and a flow path is formed between the flow path forming part 144e and the dust collection cover 141.

[0300] The flow path forming part 144e can be provided on the lower side of the dust bag drawer body 144a, and can form at least a part of the second dust collection flow path 148.

[0301] Thus, at least a portion of the second dust collection flow path 148 can be formed by combining the flow path forming part 144e and the bottom surface of the dust collection part cover 141.

[0302] On the other hand, the flow path forming portion 144e can be formed along the length direction of the dust bag drawer 144. At this time, a discharge port 144c can be formed at one end of the flow path forming portion 144e along the length direction.

[0303] Therefore, the air flowing into the outlet 144c can flow backward along the length of the flow path forming part and be discharged to the dust collection motor 145.

[0304] On the other hand, the remaining part of the second dust collection flow path 148 may be the space formed by the combination of the dust collection motor support 146c and the lower cover 146b of the dust collection motor, which will be described later.

[0305] Therefore, in this embodiment, 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. In this case, at least a portion of the first dust collection path 147 can be disposed above the second dust collection path 148.

[0306] Meanwhile, the first dust collection path 147 and the second dust collection path 148 can be formed on different surfaces of the dust collection cover 141. For example, the first dust collection path 147 is formed on the rear side of the dust collection cover 141, and the second dust collection path 148 can be formed along the lower side of the dust collection cover 141.

[0307] On the other hand, a handle 144d can be provided at the front of the dust bag drawer body 144a. The handle 144d can be configured to be gripped by a user.

[0308] Therefore, according to the present invention, the user can easily pull the dust bag drawer 144 forward, and then lift the dust bag 143 upward to remove and replace it.

[0309] 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.

[0310] On the other hand, with the bottom surface of the dust bag drawer body 141a as a reference, the filter 142 can be positioned lower than the inlet 141b. The filter 142 can be positioned in front of the outlet 144c of the dust bag drawer 144.

[0311] 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 disposed on the longitudinal (front) end of the flow path forming portion 144e. Therefore, the filter 142 can be disposed between the handle 144d and the flow path forming portion 144e.

[0312] The filter 142 can be drawn out together with the dust bag drawer 144 when the dust bag drawer 144 is drawn out.

[0313] The filter 142 can be positioned lower than the dust bag 143. In this case, the dust bag 143 can be detachably attached to the dust bag drawer 144 in a sliding manner along the vertical direction.

[0314] 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 the dust collection motor 145.

[0315] 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.

[0316] The inlet of the dust bag 143 can be configured to communicate with the inlet 144b of the dust bag drawer 144. Therefore, when the dust collection motor 145 is running, air and dust in the dust bin 220 can flow into the dust bag 143 and be captured.

[0317] The dust bag 143 can be configured to increase in volume and accommodate 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 143 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 its increased volume.

[0318] 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.

[0319] Specifically, the dust collection unit 140 may also include a dust collection motor 145 and a dust collection motor cover 146.

[0320] 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.

[0321] 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.

[0322] 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.

[0323] 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.

[0324] 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.

[0325] 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.

[0326] The dust collection motor cover 146 can internally house the dust collection motor 145. The dust collection motor cover 146 can be configured behind the dust collection unit cover 141.

[0327] In this embodiment, the dust collection motor cover 146 includes an upper dust collection motor cover 146a, a lower dust collection motor cover 146b, a dust collection motor support 146c, and a motor shock absorber 146d.

[0328] At this time, the dust collection motor 145 can be placed on the dust collection motor support 146c. The upper cover 146a of the dust collection motor can be attached to the upper side of the dust collection motor support 146c, and the lower cover 146b of the dust collection motor can be disposed on the lower side of the dust collection motor 145. On the other hand, a motor shock absorber 146d can be attached between the dust collection motor support 146c and the upper cover 146b of the dust collection motor.

[0329] With this configuration, the dust collection motor 145 can be placed on the dust collection motor support 146c, the motor shock absorber 146d can be combined, the upper cover 146a of the dust collection motor can be assembled, and the lower cover 146b of the dust collection motor can be assembled on the lower side of the cover 1110.

[0330] The upper cover 146a of the dust collection motor can cover the upper side of the dust collection motor 145. The upper cover 146a of the dust collection motor may include: a motor housing portion that houses a portion of the upper side of the dust collection motor 145; and an upper flow path forming portion that is connected to the motor housing portion and forms a flow path inside it.

[0331] The motor housing can be shaped like a cylinder and can be closed at the top. Air discharged from the dust collection motor 145 can flow in the space between the motor housing and the dust collection motor 145 and can be discharged to the upper flow path forming section.

[0332] The upper flow path forming portion can be formed by extending radially outward from the outer peripheral surface of the motor housing. This allows the flow direction of the air discharged between the motor housing and the dust collection motor 145 to be guided. In addition, the upper surface of the upper flow path forming portion can be formed with a groove to accommodate at least a portion of the pipe or hose forming the first dust collection flow path 147.

[0333] With this configuration, at least a portion of the first dust collection flow path 147 can pass through the upper side of the upper flow path forming section.

[0334] The upper flow path forming section can form at least a portion of the return flow path 125a internally. Specifically, the space formed by the combination of the upper flow path forming section and the dust collection motor support section 146c can form a portion of the return flow path 125a.

[0335] The lower cover 146b of the dust collection motor can cover the lower side of the dust collection motor 145. The lower cover 146b of the dust collection motor can be attached to the lower side of the drawer 190.

[0336] The dust collection motor support 146c can support the dust collection motor 145.

[0337] The dust collection motor support 146c can be connected to various components forming the internal structure of the robotic vacuum cleaner base station 100. The dust collection motor support 146c can be connected to the dust collection unit cover 141. The dust collection motor support 146c can be connected to the inner wall 124 or the connecting wall 123 of the mounting section 120. Thus, the dust collection motor support 146c can provide support force capable of supporting the dust collection motor 145.

[0338] The dust collection motor support 146c can be combined with the upper dust collection motor cover 146a and the lower dust collection motor cover 146b to form a return flow path 125a and a second dust collection flow path 148, respectively. As a result, multiple flow paths can be arranged in a stacked manner to maximize space utilization within a limited height.

[0339] Therefore, according to the present invention, the dust collection motor 145 can be arranged in a vertical direction, and two separate flow paths can be formed by the dust collection motor support 146c.

[0340] On the other hand, the motor shock absorber 146d is combined between the dust collection motor support 146c and the dust collection motor 145, and can elastically support the dust collection motor 145.

[0341] On the other hand, the motor shock absorber 146d can be formed from a flexible material.

[0342] Therefore, according to the present invention, by arranging the dust collection motor 145 in a vertical direction and providing a shock absorber 146d at its lower part, it is possible to reduce the vibration and noise generated by the operation of the dust collection motor 145.

[0343] 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.

[0344] 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.

[0345] 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.

[0346] 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.

[0347] 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. At least a portion of the first dust collection path 147 can be disposed above the second dust collection path 148.

[0348] 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.

[0349] The air return section 125 can guide the air discharged from the dust collection motor 145 to the robot vacuum cleaner 200.

[0350] The air return section 125 can be composed of a return flow path 125a and an air return port 125b.

[0351] The return flow path 125a provides a flow path for air discharged from the dust collection motor 145. The return flow path 125a can be formed by the dust collection motor housing 146 and the base 121. Specifically, one side of the return flow path 125a can be the space formed by the combination of the dust collection motor support 146c and the upper dust collection motor housing 146a. The other side of the return flow path 125a can be disposed inside the base body 121a. For example, the return flow path 125a can be the space formed between the upper and lower sides of the base body 121a.

[0352] Therefore, one side of the return flow path 125a can pass through the dust collection motor cover 146. Additionally, the other side of the return flow path 125a can pass through the lower side of the base 121. Meanwhile, at least a portion of the return flow path 125a can be positioned lower than the robotic vacuum cleaner 200 placed on the upper side of the base body 121a.

[0353] The return flow path 125a can be connected to the dust collection motor 145 in a flow path manner. One end of the return flow path 125a can communicate with the internal space of the dust collection motor housing 146, and the other end of the return flow path 125a can communicate with the air return port 125b.

[0354] At this time, at least a portion of the return flow path 125a can be positioned lower than the first dust collection flow path 147. Therefore, the air flowing in the first dust collection flow path 147 can intersect the flow direction of the air flowing in the return flow path 125a in the horizontal plane.

[0355] Furthermore, at least a portion of the return flow path 125a may be configured to be positioned above the second dust collection flow path 148. That is, the return flow path 125a may be configured to pass above the second dust collection flow path 148.

[0356] Therefore, by arranging (stacking) the first dust collection path 147, the second dust collection path 148, and the return path 125a vertically within a limited height, space utilization can be maximized.

[0357] An air return port 125b can be formed on the base 121. The air return port 125b can also be formed on the agitator housing 121d. In this case, the suction section 211 of the sweeping robot 200 can be disposed on the upper side of the agitator housing 121d. Therefore, the return flow path 125a can discharge air to the lower side of the suction section 211, and the air passing through the return flow path 125a can flow into the suction section 211 disposed immediately above it.

[0358] Therefore, the return flow path 125a of this embodiment of the invention can guide the air discharged from the dust collection motor 145 to the suction section 211 of the sweeping robot 200.

[0359] The return flow path 125a does not exhaust the air expelled from the dust collection motor 145 to the outside, but instead guides it to the suction section 211 of the robot vacuum 200, thereby creating a structure in which air continuously circulates between the robot vacuum 200 and the robot vacuum base station 100. As a result, the hot air expelled from the dust collection motor 145 is not exhausted into the kitchen cabinet 2, but instead flows back into the interior of the robot vacuum 200 for recirculation, thus preventing damage to the interior of the kitchen cabinet 2.

[0360] Cleaning section

[0361] Reference Figures 22 to 25 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.

[0362] 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.

[0363] 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 tank 163, a branch flow path 164, and a washing water nozzle 165.

[0364] At this time, the detergent tank 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 tank 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 tank 163.

[0365] 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.

[0366] Additionally, the detergent-containing liquid stored in the detergent tank 163 can be supplied to the mixing chamber 162 by a pump-driven flow. The detailed structure of the detergent tank 163 will be described later.

[0367] 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.

[0368] 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 supplying purified water from the regulator 161 can be connected to the purified water inlet 162a. Additionally, a flow path 163a for supplying detergent-containing liquid from the detergent tank 163 can be connected to the detergent inlet 162b. Therefore, the pumps of the regulator 161 and the detergent tank 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.

[0369] 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.

[0370] 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.

[0371] The washing water nozzles 165 can be configured in pairs. Here, a pair of washing water nozzles 165 can be configured in symmetrical positions.

[0372] 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.

[0373] The washing water nozzle 165 can be disposed on the nozzle mounting wall 123d 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 detached from the cleaning plate 122.

[0374] Furthermore, the washing water nozzle 165 can be configured to be positioned vertically upward from a position separating from the center of the cleaning protrusion 122a in the width direction. The washing water outlet 161c can be configured between the protrusion 122aa and the cleaning rib 122ab, and can be configured to be separated from the protrusion 122aa in a direction opposite to the rotation direction of the cloth 242.

[0375] The detergent container 163 includes a detergent container body 163a, a handle 163b, and a detergent container guide rail.

[0376] The detergent container body 163a provides space for storing liquid containing detergent. For example, the detergent container body 163a can be formed as a box shape with an open top.

[0377] A handle 163b may be provided at the front of the detergent container body 163a. ​​The handle 163b may be designed so that the user can hold it.

[0378] With this configuration, when the user grasps the handle 163b and pulls it forward, the detergent container body 163a can also be pulled forward and extended.

[0379] A detergent tub guide rail can be formed in the detergent tub body 163a. ​​The detergent tub guide rail can guide the movement of the detergent tub body 163a.

[0380] For example, the detergent bucket guide rail can be formed in the left and right sides of the detergent bucket body 163a in the front-back direction as a groove or rib.

[0381] With this configuration, when the user attaches the detergent container 163 to the cover 110, the detergent container 163 can be attached to the correct position, and the washing water leakage can be prevented.

[0382] On the other hand, although not shown in the figure, a guide rail can be formed on the cover 110 corresponding to the detergent tub guide rail. The guide rail can be formed in a shape and position corresponding to the detergent tub guide rail.

[0383] 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.

[0384] 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 connected to the sewage tank 166. In this case, the sewage suction pipe can be configured to pass through the lower side of the external air supply module 171.

[0385] 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 a pump (not shown) flowing through the wastewater discharge passage 167.

[0386] 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.

[0387] 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.

[0388] Cloth Drying Section

[0389] Reference Figures 26 to 30In 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 after it has been cleaned by the cloth cleaning unit 160 or the cloth 242 that is wet after the water cleaning operation is completed.

[0390] The cloth drying unit 170 may include an external air supply module 171 and an air exhaust unit 172.

[0391] The external air supply module 171 is capable of heating the air outside the enclosure 110 and supplying it to the accommodating space S. The external air supply module 171 may include an external air supply flow path 171a, an external air inlet 171b, an external air outlet 171c, a heater 171d, and a blower fan (not shown).

[0392] An external air supply flow path 171a is formed in the external air supply module 171. The external air supply flow path 171a enables external air to flow to the external air discharge section 171c.

[0393] The external air supply path 171a can connect the external space of the enclosure 110 with the receiving space. One side of the external air supply path 171a can be connected to the external space through the external air inlet 171b, and the other side of the external air supply path 171a can be connected to the receiving space S through the external air outlet 171c.

[0394] An external air inlet 171b may be formed on the rear side of the housing 110. A plurality of external air inlets 171b may be formed on the rear side of the housing 110. Air from outside the housing 110 can flow into the external air supply path 171a through the external air inlets 171b. Therefore, air from outside the housing 110 can flow into the interior of the housing 110.

[0395] At least a portion of the external air outlet 171c may be disposed on the upper side of the cleaning plate 122. The external air outlet 171c may open in a direction opposite to the cleaning plate 122. A pair of external air outlets 171c may be provided in a downward-opening state.

[0396] The external air outlet 171c can discharge air supplied through the external air supply path 171a. The external air outlet 171c can also discharge air heated in the heater 171d. For example, an external air outlet can be formed in the external air outlet 171c.

[0397] On the other hand, in this embodiment, the lateral diameter of the external air discharge portion 171c can become narrower towards the front. That is, in this embodiment, the width of the rear end of the lateral diameter of the external air discharge portion 171c can be greater than the width of the front end. As a result, even if the circular cloth 242 rotates during the drying process, the cloth 242 can be dried evenly as a whole.

[0398] On the other hand, a grille can be provided in the external air discharge section 171c to guide the discharge direction of the air. This prevents the heated air from being discharged in a way that concentrates it in a specific location.

[0399] With the cloth 242 placed on the cleaning plate 122, the external air exhaust portion 171c can open to the upper side of the cloth 242. Therefore, the external air exhaust portion 171c is located adjacent to the cloth 242, opens downward, and the air discharged from the external air exhaust portion 171c can flow towards the cloth 242.

[0400] In particular, the external air discharge section 171c of this embodiment can be configured to tilt downwards towards the front of the robot vacuum base station 100. Therefore, the end from which air is discharged from the external air discharge section 171c can be formed to tilt at a predetermined angle relative to the ground. This angle can be 90 degrees or less. Thus, the external air discharge section 171c can discharge air in a direction intersecting the direction in which the flow guide surface 122c is formed.

[0401] The blower fan 171e is configured in the external air supply flow path 171a and is capable of supplying air to the accommodating space S. When the blower fan (not shown) is driven, the air flowing in through the external air inlet 171b can be heated by the heater 171d and discharged into the accommodating space S through the external air outlet 171c.

[0402] Heater 171d is disposed in external air supply flow path 171a and is capable of heating the air flowing in external air supply flow path 171a. Heater 171d is also capable of heating the air discharged through external air outlet 171c.

[0403] The air heated by the hot air emitted from the external air supply module 171 can be discharged through the air exhaust section 172.

[0404] At least a portion of the air exhaust section 172 may be disposed in the upper part of the accommodating space S.

[0405] The air heated by the hot air emitted from the external air supply module 171 can supply heat to the mop 242 of the robotic vacuum cleaner 200. As a result, residual moisture absorbed by the mop 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 may contain vaporized moisture, and the humidity within the containment space S may increase (hereinafter, the air containing vaporized moisture within the containment space S can be referred to as "wet vapor").

[0406] Specifically, at least a portion of the air exhaust section 172 may be disposed on the upper cover 113, which may cover the upper part of the accommodating space S.

[0407] The air heated by the hot air emitted from the external air supply module 171 causes the moisture in the rag 242 to evaporate, resulting in increased humidity. Therefore, when the robot vacuum base station 100 is located under the kitchen cabinet 2, the humid steam can adversely affect various components of the kitchen cabinet 2, such as the kickboard 26, when it comes into contact with them.

[0408] In this embodiment, the upper cover 113 covers the upper part of the accommodating space S, and 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 leaking to the outside, thus preventing the kitchen cabinet 2 from coming into contact with humid steam.

[0409] The air exhaust section 172 may include an air intake 172a, an air exhaust pipe 172b, and an exhaust fan 172c.

[0410] Air intake 172a can communicate with the containment space S. Air intake 172a 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 172a.

[0411] The air intake 172a can be configured to be higher on the ground than the robot vacuum 200 when the robot vacuum 200 is placed in the mounting section 120. This increases the efficiency of the mop in drawing in rising and convection steam during drying.

[0412] As an example, an air intake 172a 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 lowermost plate has an air intake 172a, and a flow path communicating with the air intake 172a is formed between the plates, thereby forming an air exhaust pipe 172b.

[0413] As another example, the air intake 172a can be formed in the form of a circular or quadrilateral duct air exhaust pipe 172b, which can be attached to the upper cover 113.

[0414] This configuration has the following advantages: when the upper cover 113 is separated, the air exhaust pipe 172b can be separated together with the upper cover 113. In the event that the upper part of the robot vacuum base station 100 needs to be opened for reasons such as repair, the operator can remove the air exhaust pipe 172b simply by lifting the upper cover 113.

[0415] The distance from the external air outlet 171c to the air inlet 172a can be greater than the distance from the external air outlet 171c to the cloth 242. This is to prevent the heated air discharged from the external air outlet 171c from being insufficiently supplied to the cloth 242 and directly sucked into the air inlet 172a, thus wasting energy.

[0416] The air exhaust pipe 172b can be connected to the air intake 172a and the exhaust fan 172c to the drain pipe 25 of the kitchen cabinet 2. The air exhaust pipe 172b can guide the wet steam discharged through the air intake 172a to the drain pipe 25.

[0417] The air exhaust pipe 172b may have an internal air exhaust flow path that communicates with the air intake 172a.

[0418] An air exhaust path can refer to a flow path through which air flows in through an air intake 172a. For example, an air exhaust path may be formed by the internal space of an air exhaust pipe 172b, the internal space of the exhaust fan 172c housing, and the internal space of a check valve 172d. One side of the air exhaust path may be connected to the air intake 172a, and the other side may be connected to the air exhaust outlet 172e.

[0419] The exhaust fan 172c can cause airflow from the air intake 172a toward the drain pipe 25. The exhaust fan 172c can generate airflow so that the wet vapor in the containing space S, after being drawn into the air intake 172a, can be discharged to the outside through the air exhaust pipe 172b.

[0420] The exhaust fan 172c may include an exhaust fan housing, a fan motor, and an impeller. The exhaust fan housing may have an internal flow path for communication with the air exhaust pipe 172b. When the exhaust fan motor operates and the exhaust fan impeller rotates, air in the accommodating space S or housing 110 can flow into the air exhaust pipe 172b and be discharged through the interior of the exhaust fan housing to the air outlet 172e.

[0421] On the other hand, in this embodiment, the exhaust fan 172c can be combined with the external air supply module 171. Specifically, the exhaust fan housing of the exhaust fan 172c can be combined with the external air supply module 171 to form a single component. This minimizes the space occupied by the external air supply module 171 and the air exhaust section 172.

[0422] When the exhaust fan 172c is driven, air in the accommodating space S can flow into the air intake 172a. The air flowing into the air intake 172a can be discharged into the drain pipe 25.

[0423] The cloth drying unit 170 may include a check valve 172d, which prevents fluid inside the drain pipe 25 from flowing back into the air exhaust pipe 172b. The check valve 172d may be located behind the exhaust fan 172c. The check valve 172d may communicate with the internal space of the exhaust fan 172c. The check valve prevents fluid inside the drain pipe 25 from flowing back into the air exhaust unit 172.

[0424] The air exhaust section 172 can be connected downstream based on the U-bend 25a of the drain pipe 25. Specifically, the air exhaust outlet 172e can be connected to the drain pipe 25 via a flow path component. For example, the flow path component can be a flexible hose. This is because, when the air exhaust section 172 is connected upstream 25b based on the U-bend 25a of the drain pipe 25, water accumulated in the U-bend 25a may prevent the hot air exhausted through the air exhaust section 172 from passing through the drain pipe 25. Additionally, this is also to prevent foul odors generated from the air exhausted from the air exhaust section 172 from flowing back along the drain pipe 25 and spreading into the kitchen.

[0425] The wet steam discharged into the air intake 172a and through the exhaust fan 172c can be discharged to the outside of the cover 110 along the flow path component while passing through the air outlet 172e.

[0426] At this point, the flow path component can pass through either of the two sides of the outer wall and be connected to the drain pipe 25.

[0427] drawer

[0428] 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: the user may find it difficult 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.

[0429] Regarding this point, Figure 31The diagram illustrates the state in which the drawer is drawn out from the base station of the robotic vacuum cleaner according to an embodiment of the present invention.

[0430] Reference Figure 31 The drawer 190 of the robot vacuum cleaner base station 100 according to an embodiment of the present invention will be described below.

[0431] 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.

[0432] 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.

[0433] 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.

[0434] 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.

[0435] 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.

[0436] Drawer 190 includes drawer sidewalls 191, fitting part 192, and drawer slides 193.

[0437] 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.

[0438] 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.

[0439] 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.

[0440] This configuration allows for the efficient use of minimal horizontal space to arrange the dust collection unit 140 and the cloth washing unit 160.

[0441] 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.

[0442] Control Structure

[0443] Figure 32 A block diagram illustrating the control configuration in a robot vacuum cleaner base station according to an embodiment of the present invention is disclosed.

[0444] The following is for reference Figure 32 This section explains the control configuration of the robotic vacuum cleaner base station 100 of the present invention.

[0445] 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.

[0446] The control unit 300 may consist of a printed circuit board and a plurality of components mounted on the printed circuit board.

[0447] The control unit 300 can receive signals from the entry sensor 135 and can control the door drive unit 134.

[0448] 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.

[0449] 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.

[0450] The control unit 300 can drive the dust collection motor 145 to suck up the dust inside the dust bin 220 of the robot vacuum cleaner 200.

[0451] On the other hand, the robotic vacuum cleaner base station 100 in this embodiment may include a memory (not shown). The memory may contain various data for driving and operating the robotic vacuum cleaner base station 100.

[0452] On the other hand, the robotic vacuum cleaner base station 100 of this embodiment may include a communication unit 310.

[0455] On the other hand, the control unit 300 can use the communication unit 310 to confirm whether the sweeping robot 200 is located outside the enclosure 110.

[0456] The control unit 300 can control the cloth washing unit 160.

[0457] 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 tank 163 to the rag 242.

[0458] Additionally, the control unit 300 can control the regulator 161. The control unit 300 can adjust the amount of clean water dispensed onto the rag 242 by operating the regulator 161.

[0459] 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.

[0460] The control unit 300 can control the cloth drying unit 170.

[0461] Specifically, the control unit 300 can control the heater 171d. The control unit 300 can heat the air expelled to the wiping cloth 242 by operating the heater 171d.

[0462] Additionally, the control unit 300 can control the air supply fan 171e. The control unit 300 can expel air to the wiping cloth 242 by operating the air supply fan 171e.

[0463] Additionally, the control unit 300 can control the exhaust fan 172c. The control unit 300 can exhaust the air after drying the cloth 242 by operating the exhaust fan 172c.

[0464] Additionally, the control unit 300 can receive signals from the temperature sensor 174. The control unit 300 can measure the temperature of the air inside the enclosure 110 using the temperature information received from the temperature sensor 174. Furthermore, the control unit 300 can control the operation of the heater 171d based on the temperature information received from the temperature sensor 174, thereby enabling the sterilization of bacteria present in the cloth 242.

[0465] Additionally, the control unit 300 can receive signals from the humidity sensor 175. The humidity sensor 175 can be disposed on the air exhaust pipe 172b. The control unit 300 can calculate the dryness of the mop 242 based on the humidity information received from the humidity sensor 175. Furthermore, the control unit 300 can control the operation of the heater 171d to dry the mop 242 based on the humidity information received from the humidity sensor 175. In addition, the control unit 300 can control the control unit of the robotic vacuum cleaner 200 to operate the rotary plate motor 243 of the robotic vacuum cleaner 200 based on the humidity information received from the humidity sensor 175, causing the mop 242 to rotate.

[0466] Additionally, the control unit 300 can receive signals from the turbidity sensor 169. The turbidity sensor 169 can be configured in the wastewater discharge path 167. The control unit 300 can calculate the degree of cleaning of the mop 242 based on the turbidity information received from the turbidity sensor 169. Furthermore, the control unit 300 can control the operation of the regulator 161 to clean the mop 242 based on the turbidity information received from the turbidity sensor 169. At this time, the control unit 300 can control the operation time of the regulator 161 based on the turbidity information. In addition, the control unit 300 can control the control unit of the sweeping robot 200 to operate the rotary plate motor 243 of the sweeping robot 200 based on the turbidity information received from the turbidity sensor 169, causing the mop 242 to rotate.

[0467] on the other hand, Figure 33 A flowchart illustrating a control method for a robotic vacuum cleaner system according to an embodiment of the present invention is shown. Figure 34 A flowchart illustrating a control method for a robotic vacuum cleaner system according to another embodiment of the present invention is shown.

[0468] The following is for reference Figure 32 and Figure 33 This invention describes a control method for a sweeping robot system according to an embodiment of the present invention.

[0469] The control method of the robot vacuum cleaner base station according to an embodiment of the present invention includes a docking step S10, a cloth cleaning step S20, and a cloth drying step S30.

[0470] During the cleaning process, the robot vacuum cleaner 200 can store dust in the dust bin 220 and use water stored in the water bin 230, which may contaminate the mop 242.

[0471] At this time, if the robot vacuum cleaner 200 has completed cleaning the entire pre-set cleaning area, or the dustbin 220 is full of dust, or the water in the water tank 230 is used up, or the battery of the robot vacuum cleaner 200 is almost completely depleted, the control unit (not shown) of the robot vacuum cleaner 200 can control the robot vacuum cleaner 200 to return to the robot vacuum cleaner base station 100.

[0472] Therefore, if the robot vacuum cleaner 200 approaches the robot vacuum cleaner base station 100, the control method of the robot vacuum cleaner base station 100 according to an embodiment of the present invention can be executed.

[0473] First, in the docking step S10, the cleaning robot 200 is combined with the cleaning robot base station 100.

[0474] In the docking step S10, the control unit 300 can use the entry sensor 135 to sense the approach of the robotic vacuum cleaner 200 and control the door drive unit 134 to rotate the door 131. Specifically, if the distance between the robotic vacuum cleaner 200 and the door 131 is less than a preset distance, the control unit 300 can rotate the door 131 to open the entrance 127.

[0475] Therefore, the control unit 300 can operate the door drive unit 134 in one direction, causing the door 131 to rotate into an open entrance / exit 127.

[0476] Afterwards, the robot vacuum cleaner 200 can climb onto the base 121 of the mounting section 120. If the robot vacuum cleaner 200 climbs onto the base 121, the power supply terminal 123b can contact and electrically connect with the charging terminal 280 of the robot vacuum cleaner 200.

[0477] Meanwhile, the water supply nozzle 123c can be connected to the supply section 231 of the water tank 230 of the robot vacuum cleaner 200.

[0478] In addition, the mop 242 of the robot vacuum cleaner 200 can be disposed on the upper side of the cleaning plate 122, and at least a portion of the lower end of the mop 242 can contact the cleaning protrusion 122a of the cleaning plate 122.

[0479] At this time, 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.

[0480] Furthermore, if it is determined that the robot vacuum cleaner 200 has been attached to the mounting section 120, the control section 300 can operate the door drive section 134 in the opposite direction to the stated direction, causing the door 131 to rotate and close the entrance / exit 127.

[0481] In the cloth cleaning step S20, the control unit 300 can clean the cleaning cloth 242 of the sweeping robot after the docking step S10.

[0482] With the cloth 242 positioned on top of the cleaning plate 122, the control unit 300 can operate the regulator 161 to discharge clean water flowing from the water supply pipe onto the cloth 242.

[0483] At this point, the decision of whether or not to add detergent may vary depending on the user's chosen pattern.

[0484] Specifically, the control unit 300 can dispense detergent stored in the detergent tank 163 to the dishcloth 242 by operating the detergent pump 163b. At this time, the control unit 300 can operate the detergent pump 163b and the regulator 161 simultaneously, or it can maintain a time interval between their operation. Thus, clean water and detergent can be supplied to the dishcloth 242 simultaneously or at time intervals.

[0485] On the other hand, the control unit 300 can control the rotary motor 243 of the sweeping robot 200 through the communication unit 310. Thus, the mop 242 can be rotated even when clean water and detergent have been supplied to the mop 242 (i.e., the mop 242 is wet) or when clean water and detergent are being supplied to the mop 242.

[0486] At this time, if the rotary plate motor 243 rotates in one direction, the rotary plate 241 can move downwards. As a result, the cloth 242 and the cleaning plate 122 can come into contact.

[0487] Therefore, the rag 242 can rub against the cleaning protrusions 122a of the cleaning plate 122, thereby cleaning foreign matter adhering to the rag 242. This can provide an effect similar to applying detergent to the laundry before rubbing it during washing.

[0488] Afterwards, the control unit 300 can rotate the cloth 242 while the detergent pump 163b is stopped and only the regulator 161 is operated. This allows the cloth 242 to wash away any remaining detergent. This provides an effect similar to rinsing detergent during the washing process.

[0489] In contrast, the control unit 300 can operate the regulator 161 and rotate the cloth 242. This provides an effect similar to washing clothes in running water.

[0490] On the other hand, during the rag washing step S20, the control unit 300 can operate the drain pump 168. At this time, the control unit 300 can operate the drain pump 168 not only at the same time as operating the regulator 161, but also after the regulator 161 has been operated, and after a preset time has elapsed before operating the drain pump 168. As a result, the wastewater after washing the rag 242 can be discharged.

[0491] At this time, the control unit 300 can receive turbidity information of the wastewater being discharged via the turbidity sensor 169. Based on this, the control unit 300 can calculate the degree of cleaning of the rag 242 using the turbidity information received from the turbidity sensor 169.

[0492] Furthermore, the control unit 300 can determine whether to control the operation of the regulator 161 to add a cleaning cloth 242 based on the turbidity information received from the turbidity sensor 169. That is, if the received turbidity is higher than the preset reference turbidity, the control unit 300 can determine that an additional cleaning cloth 242 needs to be added and extend the operating time of the regulator 161. At the same time, the control unit 300 can extend the rotation time of the rotary motor 243 of the sweeping robot 200 through the communication unit 310. In addition, the control unit 300 can extend the operating time of the drain pump 168.

[0493] In the cloth drying step S30, the control unit 300 can supply heated air to the cloth 242 to dry the cloth 242 after the cloth washing step S20.

[0494] In the cloth drying step S30, the control unit 300 can operate the heater 171d and the air blower 171e for a preset time to dry the cloth 242. At this time, the control unit 300 can operate the heater 171d and the air blower 171e with the door 131 closed. As a result, the drying time of the cloth 242 can be shortened and the cloth 242 can be sterilized by accumulating heat inside the cover 110.

[0495] At this time, the control unit 300 can adjust the drying temperature and drying time according to the user's mode selection.

[0496] On the other hand, in the cloth drying step S30, the control unit 300 can control the rotary motor 243 of the sweeping robot 200 through the communication unit 310.

[0497] At this time, the control unit 300 can control the rotary plate motor 243 to rotate the rotary plate 241 at a preset time interval (S31). Specifically, the control unit 300 can control the rotary plate motor 243 to rotate the rotary plate 241 by 180 degrees at a preset time interval. For example, the control unit 300 can make the rotary plate 241 rotate 180 degrees every 30 minutes.

[0498] Therefore, according to the present invention, the control unit 300 enables the cloth 242 to be dried evenly throughout by rotating the cloth 242 180 degrees at a predetermined cycle.

[0499] In addition, it has the effect of preventing problems such as microbial growth caused by a part of the cloth 242 not being completely dried.

[0500] In addition, by shortening the time required for the cloth 242 to dry completely, it has the effect of improving energy efficiency.

[0501] On the other hand, according to the embodiment, the control unit 300 can rotate the rotating plate 241 after it has moved upward. Therefore, the cloth 242 can rotate while it is away from the cleaning plate 122. At this time, the rotation direction of the rotating plate motor 243 can be opposite to the rotation direction of the rotating plate motor 243 in the cloth cleaning step S20.

[0502] On the other hand, in the cloth drying step S30, the heated air inside the cover 110 can be discharged to the outside.

[0503] Specifically, in the cloth drying step S30, the control unit 300 can operate the exhaust fan 172c to expel the heated air inside the cover 110 to the outside. This allows the heat accumulated inside the cover 110 to be expelled to the outside, and also allows water vapor to be expelled to the outside.

[0504] Therefore, it has the effect of reducing the humidity inside the cover 110, preventing water vapor from being reabsorbed by the cloth 242, and expelling the odor generated during the drying process of the cloth 242 to the outside.

[0505] On the other hand, in the cloth drying step S30, the control unit 300 can receive humidity information of the exhaust air from the humidity sensor 175. Based on this, the control unit 300 can calculate the degree of dryness of the cloth 242 using the humidity information received from the humidity sensor 175.

[0506] Furthermore, the control unit 300 can determine whether to stop the rotation of the rotating plate 241 based on the humidity information received from the humidity sensor 175.

[0507] The control unit 300 can determine whether further rotation of the rotating plate 241 is needed by measuring the difference between the humidity before and after the rotating plate 241 is rotated 180 degrees (S32). Specifically, if the difference between the humidity before and after the rotating plate 241 is rotated 180 degrees is below a preset reference value, the control unit 300 can determine that further rotation of the rotating plate 241 is not necessary.

[0508] Based on this, the control unit 300 can stop the rotation of the rotating plate 241 (S33). For example, if the humidity is measured at 30-minute intervals, and the humidity difference is less than 5%, the control unit 300 can stop the rotation of the rotating plate 241.

[0509] On the other hand, refer to Figure 34In another embodiment of the present invention, the control unit 300 can determine whether further rotation of the rotating plate 241 is required (S32') by the rate of change of humidity. Specifically, the control unit 300 can measure the humidity at a preset time interval and calculate the rate of change of humidity relative to the previous measured humidity. If the calculated rate of change is below a preset reference value, it can be determined that further rotation of the rotating plate 241 is not required.

[0510] Based on this, the control unit 300 can stop the rotation of the rotating plate 241 (S33). For example, if the absolute value of the difference AB between the previously measured humidity A and the currently measured humidity B divided by the value of the previously measured humidity A ((AB) / A) is less than 0.01, the control unit 300 can stop the rotation of the rotating plate 241.

[0511]

[0512] At this time, the control unit 300 can sense that the cloth 242 has been dried evenly.

[0513] Therefore, the time point at which the cloth 242 dries evenly can be sensed, and the time required for the cloth drying step S30 can be set based on this, thereby improving the drying efficiency.

[0514] After the cloth drying step S30, the control unit 300 can perform the charging step S40. This is because when the cloth washing step S20 is performed in the space sealed by the cover 110, the humidity inside the cover 110 rises sharply, which may cause leakage between the power supply terminal 123b and the charging terminal 280 of the robot vacuum cleaner 200.

[0515] Furthermore, after the cloth drying step S30, the control unit 300 can execute the dust collection step S50. At this time, the dust collection step S40 can be executed simultaneously with the charging step S40.

[0516] In the docking step S10, if the robot vacuum cleaner 200 is docked with the robot vacuum cleaner base station 100, the dust discharge port 221 can face each other with the dust through hole 123a.

[0517] Subsequently, in the dust collection step S50, the robot vacuum base station 100 can collect the dust in the dust bin 220 of the robot vacuum 200.

[0518] In the dust collection step S50, the control unit 300 can operate the dust collection motor 145 to collect the dust inside the dust bin 220 into the dust bag 143. At this time, the dust bin door 222, which was originally blocking the dust outlet 221, opens under the suction of the dust collection motor 145, and the dust stored inside the dust bin 220 can be collected into the dust bag 143.

[0519] Therefore, it has the effect of automatically emptying the dustbin 220 of the robot vacuum cleaner 200.

[0520] 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 improved by those skilled in the art within the scope of the technical concept of the present invention.
