The present invention relates to a floor sweeping robot base station in which a plurality of flow paths for connecting a dust bag and a dust collection motor are required in order to collect the collected dust in a dust bucket of a floor sweeping robot, and the space efficiency can be maximized by stacking the plurality of flow paths in the vertical direction.

Description

Technical Field

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

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

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

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

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

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

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

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

[0009] However, in the robot vacuum station, an open space is formed below the washing machine, allowing the robot vacuum to enter. A device for supplying detergent and water for cleaning wet cloths is provided on the vertical upper side of the space where the robot vacuum enters, and a dust bag is provided on the side of the space where the robot vacuum enters.

[0010] With this configuration, the height of the entire robot vacuum base station will increase, thus limiting the use of the lower space of cabinets, including sink cabinets, for installing the robot vacuum base station.

[0011] In addition, since the robot vacuum cleaner base station needs to be installed under the washing machine, space must be prepared for the installation of the washing machine. The height of the washing machine itself must be taken into account as well as the height of the robot vacuum cleaner, which limits the availability of installation space that exceeds the required height.

[0012] On the other hand, in the aforementioned robot vacuum station, the dust from the robot vacuum's dustbin is collected into a dust bag located on the side and then discharged into the space behind the robot vacuum station.

[0013] However, the space under kitchen cabinets is usually blocked by baseboards or other obstructions, making it difficult to clean frequently. As a result, a lot of dust accumulates in the lower part of kitchen cabinets.

[0014] In addition, because there are water pipes installed in the kitchen cabinets, the surrounding humidity may be high, and the outer frame may be blocked by footboards, etc.

[0015] As described above, there is a limitation that if air exhausted from the dust collection motor is discharged into the lower space of the kitchen cabinets, dust will scatter and spread into the room.

[0016] At the same time, because the air heated by the operation of the dust collection motor is filled under the kitchen cabinets, the temperature under the kitchen cabinets may rise, and the space under the kitchen cabinets becomes hot and humid, which may cause pollution. Summary of the Invention

[0017] The problem to be solved

[0018] The present invention is proposed to improve the problems existing in the existing robot vacuum base stations as described above, and its purpose is to provide a robot vacuum base station that can be embedded in the lower side of a kitchen cabinet without the need for additional installation space.

[0019] In addition, the purpose is to provide a robot vacuum station that can accommodate a robot vacuum in the lower space of a kitchen cabinet with a specified height limit.

[0020] In addition, the purpose is to provide a robot vacuum station that, when combined with a robot vacuum, can automatically collect dust from the robot vacuum's dustbin.

[0021] In addition, its purpose is to provide a flow path for dust collection that can be configured within a limited height and lateral space, thereby enabling the creation of a compact robotic vacuum cleaner base station.

[0022] In addition, the purpose is to provide a robot vacuum base station that draws in hot air exhaled from the dust collection motor into the suction unit of the robot vacuum, so as to prevent hot air from occupying the interior of the kitchen cabinet and thus prevent damage to the interior of the kitchen cabinet.

[0023] In addition, the purpose is to provide a robot vacuum base station that, when combined with a robot vacuum, can automatically clean the robot vacuum's mop through a mop cleaning unit.

[0024] In addition, the purpose is to provide a robot vacuum cleaner base station that uses the kitchen's water supply and drainage pipes to wash the rags, so that users do not need to add water or drain wastewater.

[0025] In addition, the purpose is to provide a robot vacuum cleaner base station that can automatically dry the mop cloth by supplying hot air to the mop cloth after cleaning it.

[0026] Technical solutions to the problem

[0027] To achieve the objectives described above, the sweeping robot base station of the present invention can maximize space efficiency by stacking multiple flow paths required for dust collection in the vertical direction.

[0028] Specifically, the robot vacuum cleaner base station of the present invention includes: a cover; a mounting part disposed on the cover, wherein at least a portion of the robot vacuum cleaner is coupled to the mounting part; and a dust collection part for collecting dust inside the dust bin of the robot vacuum cleaner; the dust collection part includes: a dust collection motor for providing suction to draw in dust from the dust bin; a dust collection motor cover for housing the dust collection motor; and a return flow path communicating with the internal space of the dust collection motor cover, wherein air discharged from the dust collection motor flows through the return flow path; the return flow path discharges air toward the lower side of the suction part of the robot vacuum cleaner.

[0029] This allows the air discharged from the dustbin of the robotic vacuum cleaner to flow back into the suction section of the robotic vacuum cleaner.

[0030] At this time, the mounting part may also include a base that contacts the wheels of the sweeping robot; at least a portion of the return flow path can pass through the underside of the base.

[0031] Therefore, at least a portion of the return flow path can be configured on the underside of the robotic vacuum cleaner.

[0032] Additionally, the placement part may include: a cleaning plate that contacts the mop of the sweeping robot; and a cleaning tank disposed on the rear side of the base and below the cleaning plate; the cleaning tank may include: a cleaning tank base surface on which fluid passing through the cleaning plate flows; and a flow path forming part that protrudes upward from the cleaning tank base surface and forms the return flow path on the lower side.

[0033] Furthermore, at least a portion of the cleaning plate may be disposed on the upper side of the flow path forming portion. That is, a return flow path cover portion of the cleaning plate may be disposed on the upper side of the flow path forming portion.

[0034] On the other hand, the dust collection unit may further include: a dust collection unit cover, into which dust from inside the dust bin flows; and a first dust collection flow path, connecting the space inside the dust bin and the space inside the dust collection unit cover; at least a portion of the return flow path may be configured at a lower position than the first dust collection flow path.

[0035] Additionally, the dust collection section may include a second dust collection flow path connecting the internal space of the dust collection section cover and the internal space of the dust collection motor cover; at least a portion of the first dust collection flow path may be configured on the upper side of the second dust collection flow path.

[0036] At this time, the first dust collection path can be formed in a direction intersecting the vertical direction. Additionally, the second dust collection path can be formed in a direction intersecting the vertical direction. Furthermore, the return path can be formed in a direction intersecting the vertical direction.

[0037] At this time, the dust collection motor cover can be positioned behind the dust collection unit cover.

[0038] In addition, the dust collection motor cover can be configured at a position further back than the first dust collection flow path.

[0039] Therefore, the flow directions of the air flowing in the first dust collection path and the air flowing in the return path can intersect each other.

[0040] Invention Effects

[0041] As described above, the robot vacuum base station according to the present invention can be configured in a direction horizontal to the robot vacuum, and can charge the robot vacuum, collect dust, and clean the mop, thereby having the effect of utilizing the space under the kitchen cabinet.

[0042] In addition, the robot vacuum cleaner is surrounded by a charging terminal, a dust collection unit, a mop washing unit, and a mop drying unit, thus enabling it to perform various functions of the robot vacuum cleaner simultaneously.

[0043] In addition, the other sides are covered by kitchen cabinets, thus providing aesthetic appeal to users in terms of decoration.

[0044] In addition, since the robot vacuum cleaner automatically collects dust from its dustbin, users only need to empty the dust bag at a set interval, which reduces the user's workload.

[0045] In addition, the purpose is to provide a flow path for dust collection that can be configured within a limited height and lateral space, thereby enabling a compact, overall-sized robotic vacuum cleaner base station.

[0046] In addition, the hot air exhaled from the dust collection motor is drawn into the suction unit of the robot vacuum cleaner to prevent hot air from entering the interior of the kitchen cabinets, thereby preventing damage to the interior of the kitchen cabinets.

[0047] In addition, if combined with a robot vacuum cleaner, it can automatically clean the robot vacuum cleaner's mop, thus reducing the hassle of separating and washing the mop separately.

[0048] In addition, since detergent can be added as needed, it can improve the cleaning effect of the cloth.

[0049] In addition, since the kitchen's water supply and drainage pipes are used to wash the rags, it reduces the hassle of requiring users to add water or drain wastewater.

[0050] In addition, since the mop cloth can be automatically dried by supplying hot air to it after washing, it can prevent the odor caused by wet mop cloth. Attached Figure Description

[0086] Kitchen cabinets and robot vacuum systems

[0087] 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.

[0088] The sweeping robot 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.

[0089] In addition, kitchen cabinet 2 can be equipped with an upper panel (workbench) that can function as a sink, cooking table, or work surface.

[0090] For example, kitchen cabinet 2 may include a sink cabinet with a sink unit on the upper shelf that provides space for washing dishes. Alternatively, kitchen cabinet 2 may include a cooking countertop for performing cooking tasks. Additionally, kitchen cabinet 2 may include a gas stovetop with a gas cooktop, induction cooker, pressure cooker, or oven mounted on the upper shelf.

[0091] 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.

[0092] In another embodiment of the present invention, the sweeping robot 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.

[0093] 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 cabinet, a sink 22a can be installed on the upper panel 22.

[0094] 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.

[0095] In contrast, kitchen cabinet 2 can also be fixed to the wall of the building without legs 21. In this case, a space can also be formed between the kitchen floor and the lower side panel 23.

[0096] The sweeping robot 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).

[0097] For example, the installation space can be less than 200mm in height, and typically can be less than 160mm in height.

[0098] Therefore, according to the present invention, the sweeping system 1 is disposed in the lower space of the kitchen cabinet 2, thus having the effect of minimizing the amount of the sweeping system 1 exposed to the outside.

[0099] 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.

[0100] 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 cabinet. 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. When 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.

[0101] The sweeping robot system 1 of this embodiment can use the drain pipe 25 as described above to clean and dry the mop 242 of the sweeping robot 200.

[0102] Additionally, although not shown in the diagram, a water supply pipe may be installed in the kitchen cabinet 2. Tap water (or purified water) can be supplied to the robot vacuum system 1 through the water supply pipe.

[0103] The following describes the specific structure of the sweeping robot system 1.

[0104] Robotic vacuum cleaner system

[0105] on the other hand, Figures 3 to 5 A diagram is shown illustrating a robotic vacuum cleaner system according to an embodiment of the present invention.

[0106] The sweeping robot system 1 in the embodiments of this specification may include a sweeping robot base station 100 and a sweeping robot 200.

[0107] 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 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.

[0108] robot vacuum cleaner

[0109] on the other hand, Figures 6 to 9 A diagram is shown to illustrate a sweeping robot in a sweeping robot system according to an embodiment of the present invention.

[0110] Below, refer to Figures 6 to 9 The structure of the 200 robotic vacuum cleaner will be explained.

[0111] 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.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] In embodiments of the present invention, the main body 210 may be configured such that its width (or diameter) in the horizontal direction (parallel to X and Y) is greater than its height in the vertical direction (parallel to Z). This main body 210 helps the robotic vacuum cleaner 200 form a stable structure and provides a structure that facilitates the robotic vacuum cleaner 200 in avoiding obstacles during movement (driving).

[0119] When viewed from above or below, the main body 210 can be formed into various shapes such as circles, ovals, or quadrilaterals.

[0120] 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.

[0121] 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.

[0122] The lower body may have an intake section 211 for air to flow in and a hole for accommodating a pair of wheels 260.

[0123] 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.

[0124] 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.

[0125] 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.

[0126] 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.

[0127] 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.

[0128] 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.

[0129] 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.

[0130] The dust bin 220 can suck in external dust and air to store dust.

[0131] 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.

[0132] 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.

[0133] 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.

[0134] 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.

[0135] 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.

[0136] 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.

[0137] 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.

[0138] 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.

[0139] 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.

[0140] 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.

[0141] 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 on the upper side of a pair of rotating plates 241 or the rotating plates, so that the liquid inside the bucket 230 can be supplied to a pair of wiping cloths 242 respectively.

[0142] 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.

[0143] 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.

[0144] The rotating cleaning unit 240 includes a rotating plate 241 and a cleaning cloth 242.

[0145] 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.

[0146] 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.

[0147] 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 laid horizontally, 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 B or can be tilted relative to the floor surface B. The rotating plate 241 can be formed into a circular plate shape, the bottom surface of the rotating plate 241 can be generally circular, and the rotating plate 241 as a whole can be formed into a rotationally symmetrical shape.

[0148] A pair of rotating plates 241 can achieve left-right symmetry.

[0149] The rag 242 can be attached to the underside of the rotating plate 241 so that it faces the B side of the floor.

[0150] 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 B, or it can be inclined relative to the floor surface B.

[0151] 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.

[0152] On the other hand, although not shown, the rotating cleaning unit 240 may be provided with a drive unit that applies rotational force to the rotating plate 241. For example, the drive unit may have a motor and at least one gear. Therefore, when the drive unit is running, the rotating plate 241 and the mop 242 can rotate and wipe the floor surface.

[0153] 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.

[0154] 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.

[0155] 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.

[0156] Wheel 260 can be installed on the main body 210 and can roll on the floor surface.

[0157] 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.

[0158] 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.

[0159] 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.

[0160] 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.

[0161] 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.

[0162] 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.

[0163] 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).

[0164] In addition, the battery can supply power to the sensor unit (not shown) and the control unit (not shown).

[0165] 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.

[0166] Robot vacuum cleaner base station

[0167] Figure 10 A perspective view of a robot vacuum cleaner base station used to illustrate embodiments of the present invention is shown. Figure 11 It shows Figure 10 Top view.

[0168] Below, refer to Figure 10 and Figure 11 The sweeping robot base station 100 of the present invention will be described.

[0169] 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.

[0170] The robot vacuum cleaner base station 100 may include a cover 110.

[0171] 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.

[0172] The inside of the cover 110 can be formed with a space that can accommodate the placement part 120, the dust collection flow path 147, 148, the dust collection part 140, the dust collection motor 145, the cloth washing part 160, the cloth drying part 170, and the return flow path.

[0173] 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.

[0174] The enclosure 110 includes a pair of outer walls 111 facing each other. The outer walls 111 may refer to surfaces formed along the direction of gravity.

[0175] As one example, a pair of outer walls 111 can be installed at predetermined intervals on the lower side of the kitchen cabinet 2. As another example, the cover 110 can also include a bottom surface facing the kitchen floor, and the pair of outer walls can be connected using the bottom surface. As yet another example, the cover 110 can also include a bottom surface facing the kitchen floor and an upper surface 113 facing the lower side panel 23 of the kitchen cabinet 2, and the upper and lower ends of the pair of outer walls 111 can be connected to each other using the bottom surface and the upper surface 113. Thus, 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 cleaner 200 and the robot vacuum cleaner base station 100. As yet another example, the cover 110 can also include the bottom surface, the upper surface 112, and a rear surface 111b facing the wall of the building.

[0176] With this configuration, the components of the robot vacuum cleaner base station 100 can be accommodated inside the housing 110 (between one pair of outer walls).

[0177] Additionally, the robotic vacuum cleaner 200 can be housed inside the enclosure 110. The enclosure 110 can be configured such that the gaps between its outer walls 111 are 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.

[0178] 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 126 is provided with reference to the interior of the robotic vacuum cleaner base station 100.

[0179] 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.

[0180] In addition, based on the view 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.

[0181] 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.

[0182] 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 covered by the outer wall and are arranged in the lower part of the kitchen cabinet 2. At this time, the part of the lower part of the kitchen cabinet 2, except for the robot vacuum base station 100, can be finished by the baseboard 26, so that only the front of the cover 110 is exposed to the outside.

[0183] This minimizes the external exposure of the robot vacuum base station 100 and the robot vacuum 200.

[0184] 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.

[0185] On the other hand, although not shown, the cover 110 may have spaces for a water supply hose connected to a water supply pipe to pass through, and spaces for a drainage hose to pass through for draining wastewater generated after washing the cloth 242, and spaces for a hose to pass through for draining water generated during the drying process of the cloth 242. For example, at least one of the outer wall 111 and the upper side 112 of the cover 110 may have spaces through which a plurality of such hoses can pass.

[0186] Joint

[0187] like Figure 11 As shown, the robot vacuum cleaner base station 100 may include a mounting unit 120.

[0188] 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.

[0189] The mounting section 120 can be installed inside the cover 110.

[0190] In this case, according to the embodiment, the placement part 120 can be configured to be drawn out from the cover 110 by means of the drawer 190.

[0191] With the configuration described above, the user can easily access and manage the installation section 120 when it needs cleaning or repair, or when a part needs to be replaced.

[0192] An entrance 127 for the robotic vacuum cleaner 200 to enter can be formed in the installation section 120. The entrance 127 can refer to the space formed in front of the robotic vacuum cleaner base station 100.

[0193] The entrance / exit 127 can be formed to a size that allows the robot vacuum cleaner 200 to pass through. That is, the height of the entrance / exit 127 is greater than the height of the robot vacuum cleaner 200. In this case, the entrance / exit 127 can refer to a space formed vertically upward from the front end of the base 121, and the upper end of the entrance / exit can be the same as the lower side of the lower side panel 23 of the kitchen cabinet 2 or the upper end of the cover 110.

[0194] Furthermore, the entrance / exit 127 is configured such that its width in the left-right direction is greater than the maximum width of the sweeping robot 200. In this case, at least one of the dust collection section 140 and the mop cleaning section 160 can be arranged on the left and right sides of the entrance / exit 127. Thus, the left and right ends of the entrance / exit 127 can form boundaries with the dust collection section 140 and the mop cleaning section 160. If neither the dust collection section 140 nor the mop cleaning section 160 is present, the outer wall surface of the cover 110 can also serve as the boundary.

[0195] At this time, the entrance / exit 127 can be opened and closed by the door 126. The door 126 may be provided with a rotating shaft, which is disposed at the upper or lower end of the entrance / exit 127 and is arranged in a direction parallel to the base 121. The door 126 may be hinged relative to the cover 110. Alternatively, the door 126 may be hinged relative to the inner wall 124 of the mounting portion 120.

[0196] Door 126 can be rotated by door drive unit 126a. As an example, door drive unit 126a can be a motor.

[0197] For example, the door 126 can be formed in the shape of a rectangular flat plate, and a hinge portion 126b can be provided at the upper end of the door 126. A door drive portion 126a can be connected to the axial end of the hinge portion 126b. In this case, the hinge portion 126b of the door 126 can be directly connected to the shaft of the door drive portion 126a, or it can be connected in a way that allows power to be transmitted through at least one gear.

[0198] The door 126 can remain closed (entrance / exit 127) while the robot vacuum 200 is housed in the mounting section 120. Furthermore, it can rotate to open the entrance / exit 127 when the robot vacuum 200 begins to move from the mounting section 120. The door 126 can also rotate to close the entrance / exit 127 after the robot vacuum 200 has passed through it. Additionally, if the robot vacuum 200 approaches from outside the robot vacuum base station 100, the door 126 can rotate to open the entrance / exit 127.

[0199] The placement part 120 may include a receiving space S, a base 121, a connecting wall 123, and an inner wall 124.

[0200] The robotic vacuum cleaner 200 can be housed in the receiving space S of the placement section 120. As one example, the receiving space S can be the space surrounded by the base 121, the connecting wall 123, and the inner wall 124. As another example, the receiving space S can be the space surrounded by the base 121, the cleaning plate 122, the connecting wall 123, and the inner wall 124. As yet another example, the receiving space S can be the space where the robotic vacuum cleaner 200 is located when it is connected to the power supply terminal 123b, or the space where the robotic vacuum cleaner 200 is located when its dustbin 220 is connected to the dust passage hole 123a.

[0201] The base 121 can be configured to contact the floor surface of the robot vacuum base station 100, and to support the robot vacuum 200 when the robot vacuum base station 100 is combined 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.

[0202] 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.

[0203] 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.

[0204] The base body 121a can be formed with a shape in which the width (or diameter) in the horizontal direction (parallel to X and Y) is greater than the height in the vertical direction (parallel to Z). With this structure, the robot vacuum cleaner base station 100 can be stably supported on the floor surface.

[0205] 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.

[0206] The inclined part 121b can be configured in the bottom component body 121a as an entry point for the sweeping robot 200 to climb.

[0207] The inclined section 121b may have a slope in the forward direction toward which the robot vacuum 200 enters. More specifically, in the inclined section 121b, the front end of the entrance side may be connected so that there is no height difference with the ground, while the slope increases towards the front in the direction toward which the robot vacuum 200 enters. In this case, "front" in the direction toward which the robot vacuum 200 enters refers to the rear when the robot vacuum base station 100 is used as a reference. As a result, the robot vacuum 200 can easily climb onto the robot vacuum base station 100 from the ground.

[0208] A wheel guide 121ba may be provided in the inclined section 121b.

[0209] The wheel guide portion 121ba can be formed in a groove shape to guide the movement of the wheels 260 of the robotic vacuum cleaner 200. The surface of the wheel guide portion 121ba can be formed to correspond to the surface of the wheels 260, so that the robotic vacuum cleaner 200 can move stably. In addition, the wheel guide portion 121ba can be formed such that the width of the groove at the entrance where the robotic vacuum cleaner 200 climbs is greater than the width of the wheels 260, and the width of the groove gradually narrows towards the front of the climbing path of the robotic vacuum cleaner 200 compared to the entrance. As a result, the wheels 260 of the robotic vacuum cleaner 200 can easily enter the robotic vacuum cleaner base station 100, while lateral movement is restricted by the gradually narrowing groove, thereby guiding the wheels 260 to the correct position.

[0210] An auxiliary wheel guide 121bb may be provided in the inclined section 121b.

[0211] 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 such that when the wheel 260 of the robotic vacuum cleaner 200 is placed on the wheel guide 121bb, it connects with the auxiliary wheel 270. Thus, when the robotic vacuum cleaner 200 moves on the tilting section 121b, it is supported not only by the wheel 260 but also stably supported by the auxiliary wheel 270.

[0212] The wheel 260 of the robotic vacuum cleaner 200, which moves upward along the wheel guide 121ba, can be mounted at the wheel engagement portion 121c. If the wheel 260 of the robotic vacuum cleaner 200 is mounted at the wheel engagement portion 121c, the robotic vacuum cleaner 200 and the robotic vacuum cleaner base station 100 can be physically connected. The surface of the wheel engagement portion 121c can be formed correspondingly to the surface of the wheel 260 to allow the robotic vacuum cleaner 200 to stop stably. The wheel engagement portion 121c can extend from the upper end of the wheel guide 121ba. The wheel engagement portion 121c can be connected to the wheel guide 121ba without any steps. Therefore, the robotic vacuum cleaner 200 can easily move to the wheel engagement portion 121c via the tilting portion 121b.

[0213] The wheel engagement portion 121c can be configured at the stop position of the left and right side wheels 260 of the robotic vacuum cleaner 200 to stop the robotic vacuum cleaner 200 in an accurate position. Here, the stop position of the wheels 260 refers to the stop position set for connecting the robotic vacuum cleaner 200 to the power supply terminal 123b and / or the stop position set for connecting the dustbin 220 of the robotic vacuum cleaner 200 to the dust passage hole 123a.

[0214] The wheel engagement portion 121c can be shaped into an arc shape corresponding to the shape of the wheel 260 of the robotic vacuum cleaner 200. With this configuration, the robotic vacuum cleaner 200 can move along the wheel guide portion 121ba and stop when the wheel 260 is inserted into the wheel engagement portion 121c, and the wheel 260 can be stably positioned in the arc-shaped wheel engagement portion 121c.

[0215] At least a portion of the agitator 250 of the robotic vacuum cleaner 200 can be accommodated in the agitator receiving portion 121d. Specifically, the agitator receiving portion 121d can provide space to accommodate the lower end of the agitator 250 of the robotic vacuum cleaner 200 when the wheels 260 of the robotic vacuum cleaner 200 are mounted in the wheel engagement portion 121c.

[0216] An agitator receiving portion 121d can be formed between the wheel engagement portions 121c. The agitator receiving portion 121d can be shaped to correspond to the agitator 250 of the robotic vacuum cleaner 200. The agitator receiving portion 121d can be shaped as a cuboid with an open upper portion. The bottom surface of the agitator receiving portion 121d can be sealed by the bottom surface of the base body 121a or the bottom surface of the cover 110. Thus, the agitator 250 of the robotic vacuum cleaner 200, which moves upward along the inclined portion 121b, can be placed into the recessed portion 121da through the open top surface of the agitator receiving portion 121d. At this time, the depth of the recessed portion 121da can be shallower than the depth of the wheel engagement portion 121c.

[0217] The agitator receiving portion 121d may include a recessed portion 121da and a protruding portion 121db.

[0218] The recess 121da can be formed as a recess in the base 121. The recess 121da can form a receiving space for accommodating at least a portion of the agitator 250. Thus, with the wheels 260 of the sweeping robot 200 mounted in the wheel engagement portion 121c, at least a portion of the agitator 250 can be accommodated in the receiving space of the recess 121da.

[0219] The receiving space of the recess 121da can communicate with the receiving space S of the placement part 120.

[0220] The protrusion 121db can be formed to protrude from the base 121. The protrusion 121db can be arranged along the edge of the recess 121da. In addition, when the agitator 250 is accommodated in the accommodating space of the recess 121da, the protrusion 121db can be configured to be separated from the main body 210 of the sweeping robot 200 by a predetermined distance.

[0221] The protrusion 121db can guide the air discharged through the air return port 125b to the suction section 211 of the robot vacuum cleaner 200. Thus, the air discharged into the receiving space of the recess 121da can be guided by the protrusion 121db to the suction section 211 of the robot vacuum cleaner 200.

[0222] 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.

[0223] 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.

[0224] A dust passage hole 123a can be formed in the mounting section 120 to allow air from outside the cover 110 to flow inward. Specifically, a dust passage hole 123a can be formed in the connecting wall 123 to allow air from outside the cover 110 to flow inward. In this case, the dust passage hole 123a can be disposed behind the dust collection section cover 141 described later.

[0225] The dust passage 123a can communicate with the dust bin 220 of the robotic vacuum cleaner 200. The dust passage 123a can also communicate with the dust outlet 221 of the dust bin 220 of the robotic vacuum cleaner 200. The dust passage 123a can be formed in a shape corresponding to the shape of the dust bin 220 to allow dust from the dust bin 220 to flow into the dust collection section 140. The dust passage 123a can be formed in a shape corresponding to the dust outlet 221 of the dust bin 220.

[0226] Dust can be connected to the dust collection flow path 147, 148 through the hole 123a. Air drawn in from the dust through the hole 123a can flow through the dust collection flow path 147, 148 and then be discharged through the air return section 125.

[0227] The robotic vacuum cleaner base station 100 may include a power supply module for supplying power to the robotic vacuum cleaner 200. The power supply module includes a power supply module housing and power supply terminals 123b. Circuit boards and components for supplying power may be mounted within the power supply module housing. Furthermore, the power supply terminals 123b are positioned at the front of the power supply module housing, thus being exposed on the mounting wall 123.

[0228] 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.

[0229] The robot vacuum cleaner base station 100 may also include a water supply nozzle 123c.

[0230] The water supply nozzle 123c can be connected to the supply section 231 of the water tank 230 of the robotic vacuum cleaner 200. Specifically, the water supply nozzle 123c can be connected to the inlet of the water tank 230. The inlet is configured to connect to the water tank 230 of the robotic vacuum cleaner 200. The water supply nozzle 123c can supply water supplied from the water supply pipe of the kitchen cabinet 2 to the storage space inside the water tank 230 of the robotic vacuum cleaner 200.

[0231] The inner wall 124 is a component that spatially divides the accommodating space S of the placement section 120 and the base station 100 of the robotic vacuum cleaner. A pair of inner walls 124 can be arranged on the left and right sides of the base 121. The inner walls 124 can be connected to both ends of the connecting wall 123. The inner walls 124 can extend from the left and right sides of the base 121 in a direction intersecting the base 121. Specifically, the inner walls 124 can extend vertically from the left and right sides of the base 121. The height of the inner wall 124 can be configured to correspond to the height of the support leg 21. Specifically, the height of the inner wall 124 can be configured to be the same as the height of the support leg 21.

[0232] On the other hand, various components such as dust collection paths 147 and 148, dust collection unit 140, dust collection motor 145, detergent box 163, and wastewater tank 164 can be arranged on the outer side of the inner wall 124. Specifically, the space between the inner wall 124 and the outer wall 111 of the cover 110 can accommodate the dust collection unit 140, detergent box 163, and wastewater tank 164.

[0233] The dust collection section 140 and the detergent dispenser 163 can be slidably separated from the space between the inner wall 124 and the outer wall 111 of the cover 110. The left-right width of the dust collection section 140 and the detergent dispenser 163 can be configured to correspond to the distance between the inner wall 124 and the outer wall 111 of the cover 110.

[0234] 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.

[0235] The cleaning plate 122 can be a plate that is generally inclined downwards towards the center.

[0236] 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.

[0237] At this time, a pair of cleaning protrusions 122a can be symmetrically formed on the flow guide surface 122c. Specifically, the pair of cleaning protrusions 122a are disposed on the vertically lower side of the pair of mop pads 242 of the robot vacuum cleaner 200, facing the pair of mop pads 242, and can contact at least a portion of the pair of mop pads 242.

[0238] Furthermore, a plurality of through holes 122b may be formed on the flow guiding surface 122c, and may be formed between a pair of cleaning protrusions 122a. For example, a plurality of through holes 122b may be formed at the lowest position of the flow guiding surface 122c above the ground (kitchen floor), and may be formed between a pair of cleaning protrusions 122a. Thus, fluid expelled between the pair of cleaning protrusions 122a can be guided to the through holes 122b and flow.

[0239] On the other hand, the height of the flow guide surface 122c from the kitchen floor can increase as it moves closer to the rear of the location where the through hole 122b is formed. That is, the height of the flow guide surface 122c from the kitchen floor can increase as it moves closer to the external air exhaust portion 171c, which will be described later.

[0240] With this configuration, the flow of washing water and / or air is guided by the flow guide surface 122c and flows through the through-hole 122b into the space formed between the washing plate 122 and the washing tank 128. Thus, heated air can be supplied to the washing tank 128 through the through-hole 122b.

[0241] Therefore, if the sweeping unit 240 is driven by rotating the drive unit when the mop 242 of the robot vacuum cleaner 200 is placed on the cleaning plate 122, the mop 242 will rotate. At this time, if the mop 242 rotates while washing water is supplied to the cleaning plate, the mop 242 can be cleaned by rubbing against the cleaning protrusion 122a in the stopped state.

[0242] The cleaning tank 128 is configured to house the cleaning plate 122. The cleaning tank 128 can be disposed on the rear side of the base body 121a. The cleaning tank 128 is disposed on the underside of the cleaning plate 122 and is detachably coupled to the cleaning plate 122. The cleaning tank 128 can be formed correspondingly to the cleaning plate 122 so that the cleaning plate 122 can be inserted. Liquid passing through the cleaning plate 122 can flow into the cleaning tank 128.

[0243] The cleaning tank 128 may include: a base surface on which fluid passing through the cleaning plate 122 flows; and a cleaning tank wall extending vertically from the outer contour of the base surface. The height of the base surface from the ground (kitchen floor) can decrease as it approaches the rear of the robot vacuum base station 100. This allows the fluid passing through the cleaning plate 122 to be collected at the rear of the cleaning tank 128 and discharged externally through the wastewater inlet 164c (described later).

[0244] Dust Collection Department

[0245] Figures 12 to 16 A diagram is shown illustrating the dust collection section of a robotic vacuum cleaner base station according to an embodiment of the present invention.

[0246] Below, refer to Figures 12 to 16 as well as Figure 19 The dust collection unit 140 will be explained.

[0247] 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. That is, the dust collection unit 140 can be disposed between the housing 110 and 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. In this case, the accommodating space S can be disposed inside the mounting portion 120. Thus, the components required for dust collection can be arranged even with limited height.

[0248] The dust collection unit 140 may include a dust collection unit cover 141, a dust bag (not shown), a filter 142, and a dust bag drawer 144.

[0249] Inside the dust collection unit cover 141, there can be a space that can accommodate a dust bag (not shown), a filter 142, and a dust bag drawer 144.

[0250] The dust collection unit cover 141 has a dust bag drawer 144 that can be extended outwards inside, and a dust bag (not shown) can be stored inside the dust bag drawer 144. For example, the dust collection unit cover 141 is formed into a rectangular tube that is open at the front, and the rear internal space can be connected to the first dust collection flow path 147 and the second dust collection flow path 148.

[0251] Dust inside the dust bin 220 can flow into the dust collection unit cover 141.

[0252] 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 (not shown) is attached to the dust collection hood 141, the dust bag (not shown) can be connected to the first dust collection flow path 147 inside the dust collection hood 141.

[0253] Specifically, the dust collection unit 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.

[0254] At this time, the inlet 141a can be positioned higher than the outlet 141b. Thus, air and dust flowing in through the inlet 141a can flow downwards, and the dust can be captured by a dust bag (not shown) before the air is discharged through the outlet 141b. During this process, since the air flows from top to bottom, it has the effect of preventing air from flowing upwards or dust from scattering upwards.

[0255] A dust bag (not shown) can refer to a dust collection bag used by a dust collection motor 145 to collect dust sucked into the dust bin 220 of the robotic vacuum cleaner 200. The dust bag (not shown) can be detachably attached to the dust collection cover 141. Thus, the dust bag (not shown) can be separated from the dust collection cover 141 and discarded, and a new dust bag (not shown) can be attached to the dust collection cover 141. That is, the dust bag (not shown) can be defined as a consumable part.

[0256] The dust bag (not shown) can be configured to increase in volume when suction is generated by the dust collection motor 145, thereby enabling it to contain dust.

[0257] Therefore, the dust bag (not shown) is made of a material that allows air to pass through but prevents foreign objects such as dust from passing through. For example, the dust bag (not shown) can be made of non-woven fabric and can be in the shape of a hexahedron that corresponds to the shape of the dust collection unit cover 141 when the volume is increased.

[0258] Filter 142 can be configured between dust collection hood 141 and second dust collection flow path 148. Filter 142 can be configured at outlet 141b. Filter 142 can be a pre-filter or a high-efficiency particulate air (HEPA) filter. Air that has passed through the dust bag (not shown) can flow into the second dust collection flow path 148 via filter 142.

[0259] The dust bag drawer 144 can be combined to be extended from the dust collection unit cover 141, and the dust bag (not shown) can be accommodated inside the dust bag drawer 144.

[0260] At this time, refer to Figure 19 The dust bag drawer 144 includes a dust bag drawer body 144a, a handle 144d, and a drawer slide 144e.

[0261] The interior of the dust bag drawer body 144a can provide space for assembling a dust bag (not shown). 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 and an outlet 144c can be formed at the rear to communicate with the first dust collection path 147 and the second dust collection path 148.

[0262] For example, the dust bag drawer body 144a can be formed with different widths in the upper and lower left and right directions. For example, the upper left and right width of the dust bag drawer body 144a can be greater than the lower left and right width. That is, a step can be formed inside the dust bag drawer body 144a. This maximizes the upper space where the dust bag (not shown) is located and allows the airflow path to easily flow downwards through the dust bag (not shown).

[0263] 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 air flowing into the dust bag (not shown) through the first dust collection path 147. The inlet 144b connects the first dust collection path 147 and the dust bag (not shown). Thus, dust sucked in from the dust bin 220 of the robotic vacuum cleaner 200 can move into the dust bag (not shown) via the first dust collection path 147 and the inlet 144b.

[0264] The dust bag drawer 144 can be connected to the second dust collection path 148 via an outlet 144c formed on its lower side. The outlet 144c can be configured to guide air that has passed through the dust bag drawer 144 into the second dust collection path 148. The outlet 144c can be positioned at a different height from the inlet 144b. The outlet 144c can be configured to be lower than the inlet 144b. The outlet 144c allows the internal space of the dust bag drawer 144 to connect with the second dust collection path 148. Thus, air filtered by dust as it passes through the dust bag (not shown) can move into the second dust collection path 148 via the outlet 144c.

[0265] A handle 144d may be provided on the front of the dust bag drawer body 144a. The handle 144d may be configured to be gripped by a user. For example, the handle 144d may include a pair of hinged portions connected to the front of the dust bag drawer body 144a, and a grip portion formed to connect the pair of hinged portions for the user to grip.

[0266] With this configuration, if the user grasps the grip and pulls forward, the dust bag drawer body 144a can be pulled along with it and extended forward. Thus, according to the present invention, the user can easily grasp and pull the dust bag drawer 144 forward, and then remove and replace the dust bag (not shown) by lifting it upward.

[0267] Drawer slides 144e can be formed on the left and right sides of the dust bag drawer body 144a. The drawer slides 144e can guide the movement of the dust bag drawer body 144a.

[0268] For example, drawer slides 144e can be formed in the shape of grooves or ribs on the left and right sides of the dust bag drawer body 144a in the front and back directions.

[0269] With the configuration described above, when the user attaches the dust bag drawer 144 to the dust collection unit cover 141, it can be attached to the correct position, and the dust collection unit 140, the first dust collection flow path 147, and the second dust collection flow path 148 can be connected to the correct position, thereby reducing flow loss.

[0270] On the other hand, corresponding to the drawer slide 144e, a guide rail 141a may also be formed on the inner side of the dust collection cover 141. The guide rail 141a of the dust collection cover 141 can be formed in a shape and position corresponding to the drawer slide 144e. For example, if the drawer slide 144e is formed in a groove shape, the guide rail 141a of the dust collection cover 141 can be formed in a rib or a protruding step shape.

[0271] 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 passage hole 123a passes through the dust bag and flows to the dust collection motor 145.

[0272] 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 robot vacuum 200 is combined with the robot vacuum base station 100 and the dust is connected to the dust bin 220 of the robot vacuum 200 through the hole 123a; 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.

[0273] 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 from the placement section 120 through the hole 123a to the internal space of the dust collection cover 141. The first dust collection path 147 refers to the space between the dust bin 220 of the robotic vacuum cleaner 200 and 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 through hole 123a, or a path formed by bending laterally from the dust through hole 123a, allowing 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.

[0274] 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.

[0275] 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. In this case, the second dust collection path 148 can be configured to be lower than the first dust collection path 147. That is, at least a portion of the first dust collection path 147 can be disposed above the second dust collection path 148.

[0276] This configuration allows for the arrangement of multiple flow paths in a near-horizontal direction, thereby reducing the overall height. At the same time, by stacking them, the width in the left-right direction and the overall volume of the robot vacuum base station 100 can be minimized.

[0277] On the other hand, in this embodiment, the first dust collection path 147 and the second dust collection path 148 can be formed to pass through the same side of the dust collection cover 141. That is, the first dust collection path 147 and the second dust collection path 148 can be formed to pass through the rear side of the dust collection cover 141.

[0278] That is, in this embodiment, air can flow in from the rear side of the dust collection unit cover 141 and then be discharged to the rear again.

[0279] With this configuration, the air flowing in the first dust collection path 147 and the air flowing in the second dust collection path 148 can have different flow directions. That is, the air flowing in the first dust collection path 147 can flow from back to front, while the air flowing in the second dust collection path 148 can flow from front to back.

[0280] Therefore, according to the present invention, the space occupied by the first dust collection path 147 and the front-to-back space occupied by the second dust collection path 148 can be shared, which can improve the overall space efficiency.

[0281] The dust collection unit 140 may also include a dust collection module. The dust collection module can provide suction airflow to the dust collection flow path.

[0282] Specifically, the dust collection unit 140 may also include a dust collection motor cover 146 and a dust collection motor 145.

[0283] The dust collection motor cover 146 can be disposed inside the cover 110. The dust collection motor 145 can be housed inside the dust collection motor cover 146. The dust collection motor cover 146 can be disposed behind the dust collection section cover 141. Additionally, the dust collection motor cover 146 can be disposed behind the first dust collection flow path 147. Furthermore, the dust collection motor cover 146 can be disposed behind the second dust collection flow path 148.

[0284] That is, taking the front-to-back direction of the robotic vacuum cleaner base station 100 as a reference, the dust collection cover 141 can be positioned at the front, and a first dust collection flow path 147 and a second dust collection flow path 148 can be positioned behind the dust collection cover 141. Furthermore, the dust passage hole 123a can be positioned further rearward than the first dust collection flow path 147, and the dust collection motor cover 146 can be positioned further rearward than the second dust collection flow path 148. Additionally, the dust collection motor cover 146 can be positioned further rearward than the dust passage hole 123a.

[0285] Therefore, the dust collection unit 140 is configured along the front-rear direction of the robot vacuum cleaner base station 100, thereby reducing the overall height.

[0286] The internal space of the dust collection motor housing 146 can be connected to the second dust collection flow path 148. Thus, air flowing in the second dust collection flow path 148 can be guided to the dust collection motor 145.

[0287] The internal space of the dust collection motor housing 146 can be connected to the return flow path. Therefore, the air that has passed through the dust collection motor 145 can be guided to the return flow path.

[0288] The dust collection motor 145 can generate suction in the dust collection flow path. That is, the dust collection motor 145 can provide suction to draw dust into the dust bin 220 from the dust bag disposed in the dust collection unit cover 141.

[0289] 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.

[0290] The dust collection motor 145 can generate suction by means of 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 powered, and may include an impeller that rotates about a rotation axis as the rotor rotates. Thus, suction can be generated by the rotation of the impeller.

[0291] 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. 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 through the dust collection motor 145 and then through the return flow path and be discharged from the air return port 125b.

[0292] On the other hand, the rotation axis of the dust collection motor 145 can be configured to be nearly horizontal. With the configuration described above, the overall volume of the robot vacuum base station 100, which is installed in the kitchen cabinet 2 or the installation space 21a of the structure, can be minimized.

[0293] On the other hand, according to the embodiment, the rotation axis of the dust collection motor 145 can be configured in a vertical direction. In this case, the horizontal space occupied by the dust collection motor 145 can be minimized.

[0294] The air return section 125 can guide the air expelled from the dust collection motor 145 to the robot vacuum cleaner 200.

[0295] The air return section 125 can be composed of a return flow path 125a and an air return port 125b.

[0296] The return flow path 125a provides a flow path for the air discharged from the dust collection motor 145. The return flow path 125a can be configured inside the base body 121a. For example, the return flow path 125a can be a space formed between the upper and lower sides of the base body 121a.

[0297] Therefore, at least a portion of the return flow path 125a can pass through the lower side of the base 121. At the same time, at least a portion of the return flow path 125a can be configured at a position lower than the robotic vacuum cleaner 200 placed on the upper side of the base body 121a.

[0298] Therefore, by utilizing the remaining space inside the base 121 to form a return flow path 125a, the height of the robot vacuum base station 100 can be prevented from increasing, and since no additional space is needed to form the flow path, space efficiency can be maximized.

[0299] The return flow path 125a can be connected to the flow path of the dust collection motor 145. The return flow path can refer to the flow path connecting the internal space of the dust collection motor housing 146 and the air return port 125b. 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.

[0300] The return flow path 125a can be a flow path formed in a direction that intersects the vertical direction. For example, the return flow path 125a can be a flow path formed in a horizontal direction inside the cover 110.

[0301] 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. That is, the return flow path 125a can be configured to pass under the first dust collection flow path 147. Therefore, the flow directions of the air flowing in the first dust collection flow path 147 and the air flowing in the return flow path 125a can intersect each other on the horizontal plane.

[0302] Therefore, space efficiency can be maximized by configuring (stacking) the first dust collection path 147 and the return path 125a vertically within a limited height.

[0303] The air return port 125b can serve as an outlet for guiding the air discharged from the dust collection motor 145 into the receiving space of the recess 121da.

[0304] An air return port 125b can be formed on the base 121. An air return port 125b can also be formed on the agitator housing 121d. Furthermore, an air return port 125b can be formed on the side wall of the recess 121da. In this case, the suction section 211 of the robotic vacuum cleaner 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 directly flow into the suction section 211 disposed on the upper side.

[0305] Therefore, the return flow path 125a of this embodiment of the invention can guide the air expelled from the dust collection motor 145 to the suction section 211 of the robot vacuum cleaner 200.

[0306] The return flow path 125a guides the air expelled from the dust collection motor 145 to the suction section 211 of the robot vacuum 200 instead of expelling it to the outside, thereby creating a structure in which air continues to circulate 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 flows back into the interior of the robot vacuum 200 and circulates again, instead of being expelled into the kitchen cabinet 2, thus preventing damage to the interior of the kitchen cabinet 2.

[0307] Air passing through the dust collection motor 145 can be discharged into the receiving space S through the air return port 125b. The air discharged into the receiving space S can flow back into the suction section 211 due to the suction of the dust collection motor 145. Thus, by the suction of the dust collection motor 145, the air drawn in from the dust bin 220 can flow sequentially through the dust passage hole 123a, the first dust collection flow path 147, the dust collection section cover 141, the second dust collection flow path 148, the dust collection motor 145, the return flow path 125a, and the air return port 125b before being discharged into the receiving space S.

[0308] At this time, the dust collection motor 145 can be driven together with the suction motor (not shown) of the robot vacuum cleaner 200. Since the air discharged through the air return port 125b is also sucked into the suction section 211 by the suction force of the suction motor (not shown) in addition to the dust collection motor 145, it has the effect of improving dust collection efficiency.

[0309] Cleaning section

[0310] Figure 17 An enlarged view of the mop cleaning unit of the robot vacuum cleaner base station used to illustrate an embodiment of the present invention is shown. Figure 18 An enlarged view of the washing water supply unit of the mop cleaning section of the robot vacuum cleaner base station, used to illustrate an embodiment of the present invention, is shown. Figure 19 A diagram is shown illustrating the state of the dust collection unit and detergent dispenser extending from the base station of the sweeping robot according to an embodiment of the present invention.

[0311] Below, refer to Figures 17 to 19 The cleaning unit 160 of the robot vacuum cleaner base station 100 according to an embodiment of the present invention will be described.

[0312] The robotic vacuum cleaner base station 100 of this embodiment may include a cloth cleaning unit 160. The cloth cleaning unit 160 can clean the cloth 242 of the robotic vacuum cleaner 200 attached to the mounting unit 120.

[0313] The rag washing unit 160 may include a washing water supply unit 161 that dispenses washing water to the washing plate 122, a detergent box 163 that stores liquid containing detergent, and a wastewater tank 164 that stores the washing water after the rags 242 have been washed.

[0314] In the washing water supply section 161, washing water for cleaning the rag 242 can be formed by mixing clean water and detergent.

[0315] The washing water supply unit 161 includes a branch flow path 161a, a clean water inlet 161b, a detergent inlet 161c, a detergent pump 161d, and a washing water outlet 161e.

[0316] At this time, a pair of washing water outlets 161e can be separately arranged on the rear side of the connecting wall 123. The washing water outlets 161e can discharge washing water onto the cleaning plate 122 from the upper side of the cleaning plate 122. For example, a pair of washing water outlets 161e can be arranged on the upper side of a pair of cleaning protrusions 122a.

[0317] At this time, the purified water supplied from the water supply pipe of the kitchen cabinet 2 and passing through the regulator 162 can branch off to both sides via the branch flow path 161a and connect to the separately configured washing water outlets 161e. That is, the branch flow path 161a can be formed in the form of one pipe branching into two pipes. In this case, the end of either branch pipe can be connected to either one of the pair of washing water outlets 161e, and the end of the other branch pipe can be connected to the remaining washing water outlet 161e of the pair. Thus, the branch flow path 161a can supply washing water to the pair of washing water outlets 161e.

[0318] The washing water outlet 161e can be integrally formed with the connecting wall 123 on the rear side of the connecting wall 123, or it can be detachably connected with the connecting wall 123.

[0319] The purified water inlet 161b is configured to guide purified water supplied from the water supply pipe of the kitchen cabinet 2 to the washing water supply unit 161. Specifically, the water supply pipe of the kitchen cabinet 2 can be connected to a regulator 162, thereby allowing the flow rate supplied from the water supply pipe to be adjusted. In addition, a portion of the purified water via the regulator 162 can be supplied to the water tank 230 of the robot vacuum cleaner 200 through the water supply nozzle 123c, while the remaining portion can flow into a pair of separately arranged washing water supply units 161 through the purified water inlet 161b.

[0320] The detergent inlet 161c is configured to guide liquid containing detergent supplied from the detergent cartridge 163 to the wash water supply unit 161. Specifically, the detergent-containing liquid stored in the detergent cartridge 163 can be supplied to the wash water supply unit 161 using the detergent pump 161d.

[0321] Additionally, detergent and purified water flowing into the washing water supply unit 161 can be mixed and used as washing water. The washing water supply unit 161 can discharge washing water to the top surface of the washing plate 122 via the washing water discharge port 161e. The washing water discharge port 161e can open in a direction facing the top surface of the cloth 242 placed on the washing plate 122.

[0322] Detergent container 163 can store liquid containing detergent.

[0323] The detergent dispenser 163 includes a detergent dispenser body 163a, a handle 163b, and a detergent dispenser guide rail 163c (see attached drawing).

[0324] The detergent dispenser body 163a can provide a space for storing liquid containing detergent. For example, the detergent dispenser body 163a can be formed in the shape of a box that is open at the top, and the rear of the detergent dispenser body 163a can be connected to the washing water supply unit 161.

[0325] A handle 163b may be provided at the front of the detergent dispenser body 163a. ​​The handle 163b may be configured to be gripped by a user. For example, the handle 163b may include a pair of hinged portions connected to the front of the detergent dispenser body 163a, and a grip portion formed to connect the pair of hinged portions so that the user can grip it.

[0326] With this configuration, when the user grasps the grip and pulls forward, the detergent dispenser body 163a can be pulled forward and extended together. Therefore, according to the present invention, the user can easily pull the detergent dispenser 163 forward to dispense detergent.

[0327] Detergent box guide rails 163c can be formed on the left and right sides of the detergent box body 163a. ​​The detergent box guide rails 163c can guide the movement of the detergent box body 163a.

[0328] For example, the detergent dispenser guide rail 163c can be formed in the left and right sides of the detergent dispenser body 163a in the front-back direction as a groove or rib shape.

[0329] With this configuration, when the user attaches the detergent dispenser 163 to the cover 110, the detergent dispenser 163 can be attached to the correct position, and water leakage can be prevented.

[0330] On the other hand, although not shown, a guide rail can be formed on the cover 110 corresponding to the detergent dispenser guide rail 163c. The guide rail can be formed to correspond to the shape and position of the detergent dispenser guide rail 163c.

[0331] The wastewater tank 164 provides space for storing the washing water after washing the cloths 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 cloths 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 164b through the wastewater inlet 164c, and then into the wastewater tank 164 through the wastewater inlet 164b. 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 164c.

[0332] On the other hand, a sewage suction flow path 164b is formed in a sewage suction pipe, with a sewage inlet 164c formed at one end of the sewage suction pipe, and the other end of the sewage suction pipe communicating with a sewage tank 164. In this case, the sewage suction pipe can be configured to pass under the external air supply module 171. That is, the sewage suction flow path 164b can be configured under the external air supply module 171. Alternatively, the sewage suction flow path 164b can be configured under the external air supply flow path 171a.

[0333] Washing water stored in the wastewater tank 164 can be discharged to the drain pipe 25 of the kitchen cabinet 2 through the wastewater discharge passage 164a. One end of the wastewater discharge passage 164a can be connected to the wastewater tank 164, and the other end can be connected to the drain pipe 25. At this time, the washing water stored in the wastewater tank 164 can be discharged to the drain pipe by using a centrifugal pump (not shown) to flow through the wastewater discharge passage 164a.

[0334] The sewage discharge path 164a connected to the sewage tank 164 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 164a 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 164a.

[0335] 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 164a. The check valve may be located at the other end of the sewage discharge path 164a connected to the drain pipe 25.

[0336] On the other hand, the detergent dispenser 163 and the wastewater tank 164 can be accommodated in the space formed between the inner wall 124 and the outer wall 111 of the enclosure. The detergent dispenser 163 can be disposed on the lower side of the space between the inner wall 124 and the outer wall 111 of the enclosure, and the wastewater tank 164 can be disposed on the upper side of the detergent dispenser 163 in the space between the inner wall 124 and the outer wall 111 of the enclosure.

[0337] Cloth Drying Section

[0338] Figure 20 A perspective view of the cloth drying unit of the robot vacuum cleaner base station, used to illustrate an embodiment of the present invention, is shown. Figure 21 An enlarged view of the cloth drying section of the robot vacuum cleaner base station according to an embodiment of the present invention is shown. Figure 22 A cross-sectional view is shown to illustrate the flow of air into the hot air supply module of an embodiment of the present invention.

[0339] Reference Figures 20 to 22In one embodiment of the present invention, the robot vacuum cleaner base station 100 may include a cloth drying unit 170. At this time, the cloth drying unit 170 can dry the cloth 242 of the robot vacuum cleaner 200 that has been cleaned by the cloth washing unit 160 or the cloth 242 that is wet after the water cleaning operation is completed.

[0340] The cloth drying unit 170 of one embodiment of the present invention may include an external air supply module 171, an air exhaust unit 172, an exhaust fan 173, and a check valve 175.

[0341] The external air supply module 171 can supply hot air to the accommodating space S and 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 171e.

[0342] An external air supply flow path 171a is formed in the external air supply module 171. The external air supply flow path 171a allows external air to flow to the external air discharge section 171c.

[0343] The external air supply path 171a can connect the external space of the enclosure 110 and the receiving space S. One side of the external air supply path 171a can be connected to the external space via the external air inlet 171b, and the other side of the external air supply path 171a can be connected to the receiving space S via the external air outlet 171c.

[0344] An external air inlet 171b may be formed on the rear side of the housing 110. Multiple external air inlets 171b may be formed on the rear side of the housing 110. Air from outside the housing 110 can flow into the external air supply path 171a through the external air inlets 171b. Thus, air from outside the housing 110 can flow into the interior of the housing 110.

[0345] 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 facing the cleaning plate 122. A pair of external air outlets 171c may be provided in a downward opening state.

[0346] The external air outlet 171c can discharge air that has passed through the external air supply path 171a. The external air outlet 171c can also discharge air heated by the heater 171d. For example, an external air outlet can be formed in the external air outlet 171c.

[0347] With the cloth 242 placed on the cleaning plate 122, the external air outlet 171c can open towards the upper side of the cloth 242. Thus, the external air outlet 171c can be located adjacent to the cloth 242 and open downwards, so that the air discharged from the external air outlet 171c can flow towards the cloth 242.

[0348] The blower fan 171e can be configured on the external air supply path 171a and blow air into the accommodating space S. If the blower fan 171e 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.

[0349] The heater 171d can be configured on the external air supply flow path 171a and heat the air flowing in the external air supply flow path 171a. The heater 171d can also heat the air discharged through the external air discharge section 171c.

[0350] The heater 171d may include a heater housing and a heating element. The heater housing may be positioned on the external air supply path 171a, and a space capable of accommodating the heating element may be provided inside the heater housing. Furthermore, the heating element can heat the air flowing into the heater housing. Thus, the air heated by the heating element can be discharged into the accommodating space S through the external air outlet 171c, drying the wet cloth 242.

[0351] The air exhaust unit 172 can discharge the hot and humid air generated inside the robot vacuum base station 100 during the drying of the mop 242 into the drain pipe 25. Specifically, the air exhaust unit 172 can be connected to the drain pipe 25 of the accommodating space S and the kitchen cabinet 2.

[0352] An air discharge path can be formed in the air discharge section 172. At this time, one end of the air discharge path can be connected to the receiving space S, and the other end can be connected to the drain pipe 25. Specifically, the air intake 172a, which is one end of the air discharge path, can be connected to the receiving space S, and the air outlet 172b, which is the other end of the air discharge path, can be connected to the drain pipe 25.

[0353] On the other hand, the air intake 172a can be disposed at various positions on the accommodating space S. For example, the air intake 172a can be disposed on the connecting wall 123. For another example, the air intake 172a can be disposed on the inner wall 124. As yet another example, the air intake 172a can be disposed at a height higher than the height of the cloth 242 above the ground, and positioned further forward than the external air exhaust portion 171c. This allows air containing steam generated during the drying of the cloth 242 to be discharged.

[0354] The air exhaust section 172 can be connected to the downstream 25c based on the U-bend 25a of the drain pipe 25 of the kitchen cabinet 2. This is because when the air exhaust section 172 is connected to the upstream 25b based on the U-bend 25a of the drain pipe 25, the hot air exhausted through the air exhaust section 172 cannot pass through the drain pipe 25 due to the water accumulated in the U-bend 25a.

[0355] On the other hand, in one embodiment of the present invention, the air exhaust path can be branched into two pipes inside the cover 110 and extending through both sides of the cover 110. In this case, either branch pipe can penetrate the left outer wall of the cover 110, and the other branch pipe can penetrate the right outer wall of the cover 110. The air exhaust portion 172 penetrating the outer walls 111 on both sides of the cover 110 can be connected to the drain pipe 25. Thus, air drawn in from the air exhaust portion 172 can flow to the air exhaust ports 172b branching to both sides and be discharged downstream 25c based on the U-shaped bend 25a of the drain pipe 25.

[0356] The exhaust fan 173 can discharge air flowing in through the air intake 172a into the drain pipe 25. The exhaust fan 173 can create airflow in the air discharge section 172. The exhaust fan 173 can be configured on the air discharge flow path.

[0357] If the exhaust fan 173 is driven, air in the accommodating space S can flow into the air intake 172a. The air flowing into the air intake 172a can flow into the air exhaust section 172 and be discharged into the drain pipe 25. Specifically, the air flowing in the air exhaust section 172 due to the drive of the exhaust fan 173 can be discharged downstream 25c based on the U-bend 25a of the drain pipe 25.

[0358] The cloth drying unit 170 may include a check valve 175. The check valve 175 may be provided at the other end of the air discharge path connected to the drain pipe 25. This prevents fluid inside the drain pipe 25 from flowing back to the air discharge unit 172.

[0359] layout

[0360] Figure 23 and Figure 24 A diagram illustrating the configuration relationship of the robot vacuum cleaner base station on a horizontal plane is shown.

[0361] Below, refer to Figure 4 , Figure 23 as well as Figure 24 The configuration of the robot vacuum cleaner base station 100 according to an embodiment of the present invention will be described.

[0362] 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.

[0363] Therefore, the robot vacuum cleaner base station 100 of this embodiment is characterized in that it is configured horizontally to match the space formed between the lower side panel 23 of the kitchen cabinet 2 and the kitchen floor.

[0364] 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.

[0365] At this time, with both the dust collection unit 140 and the cloth cleaning unit 160 installed, the placement unit 120 can be positioned between the dust collection unit 140 and the cloth cleaning unit 160.

[0366] For example, an entrance / exit 127 and a door 126 can be configured at the front of the robot vacuum base station 100. Furthermore, the mounting section 120, which is connected to the robot vacuum 200, can be configured 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.

[0367] 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.

[0368] At this time, the dust bag (not shown) of the dust collection unit 140 can be configured to extend forward of the cover 110. In addition, the detergent box 163 of the cloth washing unit 160 can be configured to extend forward of the cover.

[0369] That is, a handle 144d can be provided at the front end of the dust collection section 140 so that the user can hold the dust collection section cover 141. In addition, a handle 163b can also be provided at the front end of the cloth washing section 160 so that the user can grab and pull the detergent box 163.

[0370] With the configuration described above, it is possible to provide the convenience that when a user attempts to pull out the dust bag (not shown) or detergent dispenser 163, the pull-out location can be immediately recognized, and the dust bag (not shown) or detergent dispenser 163 can be pulled out with a simple action of grabbing and pulling the handle.

[0371] On the other hand, the rear ends of the dust collection unit cover 141 and the detergent box 163 can be separated by a predetermined distance from the rear end of the cover 110. Furthermore, a dust collection motor 145 can be arranged between the rear end of the dust collection unit cover 141 and the rear end of the cover 110. This configuration facilitates the connection of the power supply wire to the dust collection motor 145. Additionally, it minimizes the overall space occupied by the mounting section 120, the dust collection unit cover 141, and the dust collection motor 145 within a limited space.

[0372] Furthermore, at least a portion of a flow path for the washing water used to clean the cloth 242 and a pump that provides the flow force for the washing water can be arranged between the rear end of the cover 110 and the rear end of the detergent dispenser 163. With the configuration described above, the path for the washing water to flow in from the water supply pipe can be minimized. Additionally, it has the effect of minimizing the overall space occupied by the housing 120, the detergent dispenser 163, and the flow path for the washing water within a limited space.

[0373] On the other hand, in the robot vacuum cleaner base station 100, the cloth drying unit 170 can be configured further rearward than the mounting unit 120. In this case, the cloth drying unit 170 can be configured between the rear end of the mounting unit 120 and the rear end of the cover 110.

[0374] Therefore, in the robot vacuum cleaner base station 100 of this embodiment, a dust collection unit 140 and a cloth washing unit 160 can be arranged on the left and right sides with the placement unit 120 as a reference, and a cloth drying unit 170 can be arranged on the rear side.

[0375] That is, in the robot vacuum cleaner base station 100 of the present invention, the dust collection unit 140, the cloth washing unit 160 and the cloth drying unit 170 can all be arranged within a specified distance range from the outer contour of the placement unit 120.

[0376] This configuration allows for the placement of the housing 120, dust collection 140, cloth washing 160, and cloth drying 170 within the narrowest possible space on a horizontal plane.

[0377] This shorter distance between the dustbin 220 and the dust collection unit 140 of the robotic vacuum cleaner 200 minimizes flow path loss. Furthermore, by minimizing the distances between the mop 242 and the mop washing unit 160, and between the mop 242 and the mop drying unit 170, the area where washing water and wastewater remain after cleaning is effectively limited.

[0378] 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.

[0379] Specifically, based on the state where the robotic vacuum cleaner 200 is integrated with the mounting section 120, at least a portion of the dust collection section 140 can be configured to be lower than the uppermost point of the robotic vacuum cleaner 200. Additionally, at least a portion of the mop washing section 160 can be configured to be lower than the uppermost point of the robotic vacuum cleaner 200. Furthermore, at least a portion of the mop drying section 170 can be configured to be lower than the uppermost point of the robotic vacuum cleaner 200.

[0380] Furthermore, based on the state where the robot vacuum cleaner 200 is integrated into the mounting section 120, the top of the robot vacuum cleaner 200 can be configured to be higher than the dust bag drawer 144. Additionally, the top of the robot vacuum cleaner 200 can be configured to be higher than the detergent dispenser 163. Furthermore, the top of the dust bag drawer 144 can be configured to be higher than the detergent dispenser 163.

[0381] As a result, in the robot vacuum base station 100 of this embodiment, in addition to the front side where the robot vacuum 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, not only can the robot vacuum 200 be charged using the smallest possible horizontal space, but it can also collect dust from the robot vacuum 200, wash the mop 242, and dry the mop 242.

[0382] drawer

[0383] When the charging dock of the robotic vacuum cleaner is positioned under the kitchen cabinet, its external exposure is minimized, thus enhancing the aesthetic appeal. However, if the robotic vacuum cleaner malfunctions while inside the cabinet or if the charging dock itself malfunctions, it presents a limitation that makes it difficult for the user to remove and repair it. To address this issue, a drawer 190 can be added to the robotic vacuum cleaner base station 100 in this invention.

[0384] Regarding this, Figure 25 A diagram is shown illustrating the state in which the base station of the sweeping robot is equipped with a drawer, according to an embodiment of the present invention. Figure 26 A diagram is shown illustrating the state of the drawer extending from the base station of the robotic vacuum cleaner according to an embodiment of the present invention.

[0385] Below, refer to Figure 25 and Figure 26 The drawer 190 of a robotic vacuum cleaner base station 100 according to an embodiment of the present invention will be described.

[0386] 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.

[0387] If the robot vacuum cleaner 200 enters the housing 120 with the drawer 190 introduced into the housing 110, the door 126 can be closed. In this case, the inside and outside of the housing 110 can be blocked by the door 126 after the robot vacuum cleaner 200 enters.

[0388] This prevents dust from scattering to the outside of the robot vacuum base station 100 while the robot vacuum 200 is inside the housing 110 and collecting dust in the dust bin 220. Additionally, it prevents wastewater from leaking to the outside of the robot vacuum base station 100 during the washing of the mop 242.

[0389] 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.

[0390] 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.

[0391] At this time, if the drawer 190 is pulled out from the cover 110 with the door 126 closed and the entrance 127 closed, the robot vacuum cleaner 200 installed in the placement section 120 can be exposed to the outside.

[0392] 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.

[0393] On the other hand, in one embodiment of the present invention, the drawer 190 can be drawn out with the dust collection section 140 housed inside. That is, the drawer 190 can be drawn out together with the dust collection section 140.

[0394] Conversely, the dust collection unit 140 of the present invention can be drawn out of the cover 110 independently of the drawer 190. In this case, the drawing direction of the dust collection unit 140 can be parallel to the drawing direction of the drawer 190. For example, the drawing direction of the dust bag drawer 144 can be parallel to the drawing direction of the drawer 190.

[0395] Furthermore, in one embodiment of the present invention, the drawer 190 can be extended with at least a portion of the cloth washing section 160 internally provided. That is, the drawer 190 can be extended together with at least a portion of the cloth washing section 160. For example, the drawer 190 can be extended together with the detergent dispenser 163 and the wastewater tank 164.

[0396] Conversely, the detergent dispenser 163 of the present invention can be drawn out of the cover 110 independently of the drawer 190. In this case, the direction in which the detergent dispenser 163 is drawn out can be parallel to the direction in which the drawer 190 is drawn out.

[0397] With this configuration, the robot vacuum cleaner base station 100 of an embodiment of the present invention can be configured such that the drawer 190, the dust collection part 140 and the detergent box 163 are all parallel in their outward directions.

[0398] Therefore, it has the effect that users can easily identify the lead-out direction of the constituent elements of the robot vacuum cleaner base station 100 of the present invention and can easily lead them out for repair and maintenance.

[0399] Drawer 190 includes drawer sidewalls 191, fitting part 192, and drawer slides 193.

[0400] The drawer sidewalls 191 are configured to be movable relative to each other between the outer wall surfaces of the cover 110. For example, a pair of drawer sidewalls 191 may be configured to face the outer wall surfaces of a pair of covers 110.

[0401] Here, the 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.

[0402] At this time, the pair of drawer sidewalls 191 can be directly connected to the base 121 of the mounting part 120. In contrast, the pair of drawer sidewalls 191 can be connected by a drawer base (not shown), or the mounting part 120 can be attached to the upper side of the drawer base (not shown) and move together.

[0403] On the other hand, a dust collection section 140 and / or a cloth cleaning section 160 may be arranged between the drawer side wall 191 and the mounting section 120. That is, based on the state in which the robot vacuum cleaner 200 is attached to the mounting section 120, a dust collection section 140 and / or a cloth cleaning section 160 may be arranged between the robot vacuum cleaner 200 and the drawer side wall 191.

[0404] This configuration allows for the efficient use of minimal horizontal space to arrange the dust collection unit 140 and the cloth washing unit 160.

[0405] Assembly part 192 is provided on drawer side wall 191, and at least one of hose and wire is attached to assembly part 192 in a detachable manner. For example, assembly part 192 may be configured on drawer side wall 191, and hose and / or wire may be attached to assembly part 192.

[0406] The assembly part 192 is combined with the drawer side wall 191. One side of the assembly part 192 is located in the inner space of the drawer 190, which is closer to the drawer side wall 191 than the drawer side wall 191. The other side of the assembly part 192 is located on the outer side of the drawer side wall 191.

[0407] At least one of the hose and the wire is detachably connected to the assembly part 192. For example, at least one of the following is detachably connected to the assembly part 192: a water supply pipe connection that is connected to a water supply pipe, a drain pipe connection that is connected to a drain pipe, an exhaust pipe connection that is connected to a steam exhaust pipe that discharges air from inside the drawer 190, and a power supply connection that is connected to a power source.

[0408] At this time, the water supply pipe of the rag washing unit 160 and the water supply pipe connected to an external water source can be respectively connected to both sides of the water supply pipe connection. In addition, the drain pipe of the rag washing unit 160 and the drain pipe connected to the upstream 25b of the U-shaped bend of the kitchen cabinet 2 can be respectively connected to both sides of the drain pipe connection.

[0409] That is, the assembly part 192 of the present invention can be a structure in which the water supply pipe and the drain pipe that use the water supply and drain pipe provided in the kitchen cabinet 2 to supply and drain water are connected to the water supply pipe and the drain pipe inside the robot vacuum base station 100 in a way that allows them to be detached from each other.

[0410] In addition, air exhaust pipes connected from the air outlet 172b of the cloth drying unit 170 can be respectively connected to both sides of the exhaust pipe connection.

[0411] Therefore, the air discharged from the cloth drying section 170 can be discharged to the downstream 25c of the U-shaped bend.

[0412] In addition, the power connection section can be equipped with a wire for connection to an external power source. In this case, the wire can be directly connected to the power connection section, or it can be connected using a wire connection mechanism such as a connector or adapter.

[0413] 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.

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.

[0435] Another embodiment

[0436] Figure 28 and Figure 29 A top view of a robotic vacuum cleaner base station illustrating another embodiment of the present invention is shown. Figure 30 An enlarged view of the flow path of the dust collection section in a robotic vacuum cleaner base station, illustrating another embodiment of the present invention, is shown. Figure 31 and Figure 32 A cross-sectional view is shown illustrating the flow path of the dust collection section in a robot vacuum cleaner base station according to another embodiment of the present invention.

[0437] Below, refer to Figures 28 to 32 The following describes another embodiment of the robot vacuum cleaner base station.

[0438] In this embodiment, except for the specially described configuration, the configuration and effect are the same as those of the robot vacuum cleaner base station of an embodiment of the present invention. Therefore, to avoid repetition, the description can be referenced.

[0439] In another embodiment of the robot vacuum cleaner base station of the present invention, the cleaning plate 1122 is a component for cleaning the cleaning cloth of the robot vacuum cleaner 200, and it can be placed on the upper side of the cleaning tank 1128 of the base 1121. In addition, the cleaning plate 1122 can contact the cleaning cloth 242 when the robot vacuum cleaner 200 is in place.

[0440] The cleaning plate 1122 may be formed as a plate that slopes downwards as it approaches the center.

[0441] Specifically, the cleaning plate 1122 includes a flow guiding surface 1122c formed in a curved shape. Furthermore, at least one through-hole 1122b through which fluid can pass may be formed in the flow guiding surface 1122c. Additionally, a cleaning protrusion 1122a may be formed protruding from the flow guiding surface 1122c.

[0442] The fluid ejected from the cleaning plate 1122 can be directed to the through hole 1122b and flow there.

[0443] With this configuration, the flow of washing water and / or air can be guided by the flow guide surface 1122c and flow out through the through hole 1122b into the space formed between the washing plate 1122 and the washing tank 1128. Thus, heated air can be supplied to the washing tank 1128 through the through hole 1122b.

[0444] On the other hand, in this embodiment, at least a portion of the cleaning plate 1122 may be disposed on the upper side of the flow path forming portion 1128c described later. That is, in this embodiment, the cleaning plate 1122 may further include a return flow path cover portion 1122d, which protrudes upward from the flow guide surface 1122c and is combined with the upper side of the flow path forming portion 1128c.

[0445] In this embodiment, the cleaning plate 1122 can be formed in a shape corresponding to the shape of the flow path forming portion 1128c. For example, the front left side portion of the cleaning plate 1122 can be formed by protruding upward from the flow guide surface 1122c and covering the lower flow path forming portion 1128c.

[0446] With this configuration, the cleaning plate 1122 and the cleaning tank 1128 can be accurately combined, while providing sufficient space to form the return flow path 1125a.

[0447] On the other hand, the cleaning tank 1128 is configured to accommodate the cleaning plate 1122. The cleaning tank 1128 can be disposed on the rear side of the base body 1121a. The cleaning tank 1128 is disposed on the underside of the cleaning plate 1122 and is detachably connected to the cleaning plate 1122. The cleaning tank 1128 can be formed correspondingly to the cleaning plate 1122 so that the cleaning plate 1122 can be inserted. Liquid that has passed through the cleaning plate 1122 can flow into the cleaning tank 1128.

[0448] The cleaning tank 1128 may include a base surface 1128a through which fluid flows via the cleaning plate 1122, and a cleaning tank wall 1128b extending vertically from the outer contour of the base surface. The height of the base surface 1128a from the ground (kitchen floor) can decrease as it approaches the rear of the robotic vacuum cleaner base station 100. This allows fluid flowing through the cleaning plate 1122 to be collected at the rear of the cleaning tank 1128 and discharged externally via the wastewater inlet 164c.

[0449] In this embodiment, the cleaning tank 1128 may have a flow path forming portion 1128c. The flow path forming portion 1128c may be formed by protruding upward from the base surface 1128a of the cleaning tank, and a return flow path 1125a may be formed on the lower side. Specifically, a return flow path 1125a may be formed between the lower side of the base 1121 and the flow path forming portion 1128c.

[0450] On the other hand, in this embodiment, one side of the interior of the dust collection cover 1141 can be connected to the first dust collection flow path 1147, while the other side can be connected to the second dust collection flow path 1148. In addition, if a dust bag (not shown) is attached to the dust collection cover 1141, the dust bag (not shown) can be connected to the first dust collection flow path 1147 inside the dust collection cover 1141.

[0451] Specifically, the dust collection section cover 1141 may have an inlet 1141a communicating with the first dust collection flow path 1147 and an outlet 1141b communicating with the second dust collection flow path 1148.

[0452] At this time, the inlet 1141a can be positioned higher than the outlet 1141b. Thus, air and dust flowing in through the inlet 1141a can flow downwards and be captured in a dust bag (not shown), before being discharged through the outlet 1141b. During this process, since air flows from top to bottom, it has the effect of preventing air from flowing upwards or dust from scattering upwards.

[0453] On the other hand, in this embodiment, the outlet 1141b can be positioned further forward than the inlet 1141a. For example, the inlet 1141a can be formed on the rear side of the dust collection shroud 1141, and the outlet 1141b can be formed on the lower side of the dust collection shroud 1141. In this case, the outlet 1141b can be positioned closer to the front side of the dust collection shroud 1141 than the rear side of the dust collection shroud 1141.

[0454] Meanwhile, the first dust collection path 1147 and the second dust collection path 1148 can be formed on different surfaces of the dust collection unit cover 1141. For example, the first dust collection path 1147 can be formed on the rear side of the dust collection unit cover 1141, and the second dust collection path 1148 can be formed along the lower side of the dust collection unit cover 1141.

[0455] On the other hand, in this embodiment, the second dust collection path 1148 can be formed in the space formed in conjunction with the dust bag drawer 1144. That is, a portion of the second dust collection path 1148 can be formed in the space formed between the lower side of the dust collection cover 1141 and the dust bag drawer 1144.

[0456] Therefore, the second dust collection path 1148 can pass under the inlet 1141a.

[0457] Therefore, dust and air flowing in from the inlet 1141a formed on the rear side of the dust collection hood 1141 can flow to the outlet 1141b formed on the lower front side of the dust collection hood 1141. During this process, the dust contained in the air can be fully separated and stored throughout the dust bag. This prevents dust from accumulating in specific locations within the dust bag.

[0458] The present invention has been described in detail above through specific embodiments, but this is only for the purpose of illustrating the present invention. The present invention is not limited thereto. Obviously, the present invention can be modified or altered by those skilled in the art within the scope of the technical concept of the present invention.

[0459] Simple variations or modifications of this invention are all within the scope of this invention, and the specific scope of protection of this invention will become clearer through the scope of the claims.
