Sweeping robot base station

Abstract

This invention relates to a base station for a robotic vacuum cleaner. Because it can independently lead out and clean the cleaning tank that may be contaminated during the cleaning process of the mop, it can reduce the inconvenience for users to lift the base station body or lie on the floor to wipe the cleaning tank in order to manage it.

Description

Technical Field

[0001] This invention relates to a base station for a robotic vacuum cleaner, and more specifically, to an embedded base station that, when used with a robotic vacuum cleaner, can collect dust from the vacuum cleaner's dustbin, clean the vacuum cleaner's mop, and dry the mop. Background Technology

[0002] In recent years, with the development of industrial technology, a type of sweeping robot is being developed that can autonomously drive and clean the area that needs to be cleaned without user intervention.

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

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

[0005] A robotic vacuum cleaner charging station is a device that allows a robotic vacuum cleaner 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, thus charging it.

[0006] On the other hand, if the charging station for the robotic vacuum cleaner is located indoors, it will occupy a designated area of ​​indoor space. In this case, it may reduce the utilization rate of indoor space. In addition, when users or pets pass by, they may collide with the robotic vacuum cleaner, which may not only cause injury to the users or pets, but also damage the robotic vacuum cleaner.

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

[0008] In this regard, Chinese authorized utility model patent CN218922467U discloses a base station for a sweeping robot, in which the sweeping robot is integrated into the lower side of the washing machine for charging the sweeping robot, collecting dust, and cleaning the sweeping robot's wet cloth.

[0009] However, in the cleaning robot base station, an open space is formed below the washing machine, allowing the cleaning robot 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 cleaning robot enters, and a dust bag is arranged on the side of the space where the cleaning robot enters.

[0010] With this arrangement, the height of the overall cleaning machine base station increases, thus limiting its installation by not being able to utilize the space under furniture, including sink cabinets.

[0011] In addition, since the cleaning machine base station needs to be installed below the washing machine, space for installing the washing machine must be secured in advance. Not only the height of the washing machine itself must be considered, but also the height of the cleaning machine base station. This results in the limitation that a space with a height exceeding the combined height of the two must be prepared.

[0012] In addition, since the space for the sweeping robot to enter and exit the base station is always open, there are limitations such as dust scattering during the dust collection process of the sweeping robot's dust bucket, and wastewater leakage during the cleaning of the sweeping robot's mop.

[0013] On the other hand, the cleaning machine base station is equipped with a cleaning tank for washing wet cloths, but it does not have a structure for separately leading out and managing the cleaning tank.

[0014] In this situation, foreign objects contained in the wastewater may accumulate in the washing tank, potentially causing an unpleasant odor. Additionally, there is a risk of recontamination of damp cloths near the washing tank.

[0015] In order to solve this problem, the cleaning machine base station needs to be separated from the washing machine and the washing tank needs to be managed separately.

[0016] On the other hand, Chinese utility model patent CN218588948U discloses a base station that includes a cleaning plate for cleaning the wet cloth of a sweeping robot.

[0017] The cleaning plate is configured to clean a wet cloth by rubbing it against the cloth. Wastewater generated during cleaning can be stored in a cleaning tank located on the underside of the cleaning plate.

[0018] However, the base station has the limitation that it can only separate the cleaning plate, but cannot separate the cleaning tank from the base station body.

[0019] In this situation, there is an inconvenience that users need to lift the base station itself or lie on the floor in order to manage the cleaning tank. Summary of the Invention

[0020] The problem that the invention aims to solve

[0021] 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 requiring additional installation space.

[0022] 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.

[0023] In addition, the purpose is to provide a robot vacuum station that can automatically collect dust from the dustbin of the robot vacuum when combined with a robot vacuum.

[0024] In addition, the purpose is to provide a robot vacuum base station that can automatically clean the robot vacuum's mop when combined with a robot vacuum.

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

[0026] In addition, its purpose is to provide a robot vacuum cleaner base station that can be brought out as needed for cleaning and maintenance.

[0027] In addition, the purpose is to provide a robot vacuum cleaner base station that can separately draw out and manage the cleaning tank that may be contaminated during the cleaning process of the rag.

[0028] In addition, the purpose is to provide a robot vacuum cleaner base station that can prevent the leakage of sewage accumulated in the cleaning tank by connecting the separate cleaning tanks to the correct position.

[0029] Technical solutions to the problem

[0030] To achieve the objectives described above, the robot vacuum cleaner base station of the present invention includes: a cover disposed in the lower part of a kitchen cabinet; a connecting part disposed in the cover to accommodate the robot vacuum cleaner; and a mop cleaning part disposed in the cover to clean the mop of the robot vacuum cleaner; the connecting part includes: a cleaning member that contacts the mop when the robot vacuum cleaner is engaged; and a cleaning tank disposed on the lower side of the cleaning member and detachably engaged with the cleaning member, through which liquid flows into the cleaning tank.

[0031] At this time, the cleaning tank can be drawn out from the cloth cleaning section.

[0032] On the other hand, the connecting part also includes a bottom component, on which the sweeping robot is mounted; the bottom component can be led out from the mop cleaning part together with the cleaning tank.

[0033] Additionally, the connection may include: a pair of sidewalls that internally accommodate the robotic vacuum cleaner; a drawer guide that protrudes from the pair of sidewalls to guide the movement of the cleaning tank; and a guide connection that is disposed on both sides of the cleaning tank and engages with the drawer guide.

[0034] As a result, the cleaning tank can be led out and led in along the sidewall and can be guided to fit into the correct position.

[0035] On the other hand, the rag cleaning unit may include a cleaning tank connection part, which is detachably connected to the cleaning tank; a sewage suction pipe may be provided in the cleaning tank connection part, and the liquid stored in the cleaning tank flows into the sewage suction pipe.

[0036] Furthermore, the cleaning tank may include a sewage suction nozzle, which is connected to the sewage suction pipe when the cleaning tank is engaged with the cleaning tank joint.

[0037] At this time, the rag cleaning unit may also include a sewage pipe connecting member, which surrounds one end of the sewage suction pipe and is combined with the cleaning tank, thereby sealing the space between the sewage suction nozzle and the sewage suction pipe.

[0038] On the other hand, the cleaning unit may be equipped with a cleaning tank connection sensor, which senses the connection of the cleaning tank; the cleaning tank may include a magnet, which is arranged in a position facing the cleaning tank connection sensor.

[0039] Therefore, if the cleaning tank is aligned with the accurate position of the cleaning tank connection, the cleaning tank connection sensor can detect that the cleaning tank is aligned with the accurate position.

[0040] At this point, the robot vacuum cleaner's base station can perform the cleaning of the mop once it senses that the cleaning tank is in the correct position.

[0041] In addition, the robot vacuum cleaner's base station can notify the user that the cleaning tank is not engaged if it is not properly aligned with the correct position.

[0042] On the other hand, according to an embodiment, the robot vacuum cleaner base station may also include a drawer extending from the cover and having a connecting part for the robot vacuum cleaner to engage with.

[0043] At this time, the cleaning section is arranged inside the drawer, and the cleaning tray can be extended out from the drawer.

[0044] That is, the cleaning tank can be drawn out together with the drawer, or it can be drawn out separately without the drawer being drawn out.

[0045] Invention Effects

[0046] As described above, according to the present invention, the modules for charging the robot vacuum, collecting dust, and cleaning the mop are arranged in a direction horizontal to the robot vacuum, thereby enabling the use of the space under the kitchen cabinet.

[0047] In addition, the charging terminal, dust collection unit, mop cleaning unit, and mop drying unit are arranged in a configuration centered around the robot vacuum, enabling the robot vacuum to perform various functions simultaneously.

[0048] In addition, the other sides besides the front are covered by kitchen cabinets, thus providing aesthetic appeal to the user in terms of decoration.

[0049] In addition, when the robot vacuum is in use, it automatically collects dust from the dustbin inside the robot vacuum, so users only need to empty the dust bag at a constant interval, which can reduce the user's workload.

[0050] In addition, when used with a robot vacuum cleaner, the robot vacuum cleaner's mop can be automatically cleaned, thus reducing the hassle of separating the mop and washing it separately.

[0051] In addition, detergent can be added as needed, thus improving the cleaning effect of the cloth.

[0052] In addition, the kitchen's water supply and drainage pipes are used to wash the dishcloths, thus reducing the hassle for users who need to separately add water or drain wastewater.

[0053] In addition, after cleaning the robot vacuum cleaner's mop, hot air can be supplied to the mop to automatically dry it, thus preventing odors from developing due to a wet mop.

[0054] In addition, during the drying process of the cloth, the dried air is discharged downstream of the U-shaped bend to prevent odor backflow.

[0055] In addition, since the cleaning tank, which may become contaminated during the cleaning process, can be brought out and cleaned separately, the inconvenience of users having to lift the base station or lie on the floor to wipe the cleaning tank in order to manage it can be reduced.

[0056] In addition, the simple action of pushing the device into the cleaning tank after cleaning allows it to be aligned with the correct position along the guide structure. The sensor can detect whether it is aligned with the correct position, thus preventing the leakage of wastewater accumulated in the cleaning tank due to inaccurate alignment.

[0084] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0085] This invention can be modified in various ways and can have various embodiments; therefore, specific embodiments are intended to be shown in the accompanying drawings, and detailed descriptions are provided in the specific embodiments. This is not intended to limit the invention to the specific embodiments, but should be interpreted as encompassing all modifications, equivalents, and substitutions included within the spirit and technical scope of the invention.

[0086] In describing this invention, the terms "first," "second," etc., can be used to describe various structural elements, but the structural elements are not limited by these terms. These terms are only used to distinguish one structural element from other structural elements.

[0087] The term "and / or" can include a combination of a plurality of related records or any one of a plurality of related records.

[0088] When it is said that a structural element is "connected" or "linked" to another structural element, it should be understood that it can be directly connected or linked to another structural element, or that other structural elements may exist between them. Conversely, when it is said that a structural element is "directly connected" or "directly linked" to another structural element, it should be understood that no other structural elements exist between them.

[0089] The terminology used in this application is for illustrative purposes only and is not intended to limit the invention. Unless explicitly stated in the context, singular expressions may include plural expressions.

[0090] Furthermore, in this application, it should be understood that terms such as “comprising” or “having” are intended only to describe the presence of features, figures, steps, actions, structural elements, components or combinations thereof described in the specification, and do not preclude the possibility of the presence or addition of one or more other features, figures, steps, actions, structural elements, components or combinations thereof.

[0091] Unless otherwise defined, all terms used herein, including technical or scientific terms, may have the meaning commonly understood by one of ordinary skill in the art to which this invention pertains. Terms such as those defined in common dictionaries may be interpreted as having a meaning consistent with their meaning in the relevant technical context and should not be interpreted as having an ideal or overly formal meaning unless expressly defined herein.

[0092] Furthermore, the following embodiments are provided to enable those skilled in the art to understand more fully, and for the purpose of clearer illustration, the shape and size of the structural elements in the drawings may be exaggerated.

[0093] Figure 1 A diagram is shown illustrating the state in which the sweeping robot system of 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 machine system according to an embodiment of the present invention is shown.

[0094] 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 arranged in the kitchen to store bowls, plates, cups, etc., and can provide space for cooking food or washing dishes.

[0095] In addition, kitchen cabinet 2 can be equipped with an upper panel (workbench) that can function as a sink, cooking table, or work surface.

[0096] For example, kitchen cabinet 2 may include a sink cabinet with space for washing dishes on the upper shelf. 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 cooktop, electric stove, or oven mounted on the upper shelf.

[0097] Typically, kitchen cabinet 2 can use a standard cabinet with a front-to-back width of 600mm.

[0098] 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 160a can refer to a flow path connected to an external water supply source that supplies fluid to the structure, and the drain pipe can refer to a flow path that discharges fluid from the structure into a sewer.

[0099] 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 arranged on the upper panel 22.

[0100] Additionally, the lower side panel 23 can be supported by legs 21. Legs 21 can be arranged perpendicular to the kitchen floor and can support the load of the kitchen cabinet 2. At this time, a space can be formed between the kitchen floor and the lower side panel 23 along the height direction of the legs 21.

[0101] 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.

[0102] 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).

[0103] For example, the installation space can be less than 200mm in height, and typically can be less than 160mm in height.

[0104] Therefore, according to the present invention, the sweeping system 1 is arranged in the lower space of the kitchen cabinet 2, thus minimizing the degree to which the sweeping system 1 is exposed to the outside.

[0105] In addition, compared to arranging a charging station for a robot vacuum cleaner in a designated space in the living room, bedroom, or kitchen, arranging the robot vacuum cleaner system 1 in the unused space created by the kitchen cabinet 2 without occupying additional space has the effect of maximizing space utilization.

[0106] 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 arranged 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 arranged in the storage space. Liquid flowing in through the drain outlet flows downward by gravity in the upstream 25b of the U-trap and accumulates in the U-trap 25a. If the water overflows above a predetermined water level set by the U-trap 25a, it can flow downward along the downstream 25c of the U-trap and be discharged into the sewer.

[0107] 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.

[0108] Additionally, a water supply pipe can be installed in the kitchen cabinet 2. Tap water (or purified water) can be supplied to the sweeping robot system 1 through the water supply pipe.

[0109] The following describes the specific structure of the sweeping robot system 1.

[0110] on the other hand, Figures 3 to 5 A diagram illustrating a sweeping robot system according to an embodiment of the present invention is shown.

[0111] The sweeping robot system 1 in the embodiments of this specification may include a sweeping robot base station 100 and a sweeping robot 200.

[0112] 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.

[0113] 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.

[0114] Below, refer to Figures 6 to 9 The structure of the 200 robotic vacuum cleaner will be explained.

[0115] 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.

[0116] The robotic vacuum cleaner 200 of this embodiment is configured to clean the floor while being placed on the floor and moving along the floor surface. Therefore, the following description will focus on the vertical direction based on the state of the robotic vacuum cleaner 200 placed on the floor.

[0117] Furthermore, taking a pair of wheels 260 as a reference, the side where the auxiliary wheel 270 (described later) is arranged is designated as the front, and the side where the rotating cleaning unit 240 (described later) is arranged is designated as the rear, and will be described in detail.

[0118] 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.

[0119] 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.

[0120] The main body 210 can form the overall shape of the robot vacuum cleaner 200. Various components that make up the robot vacuum cleaner 200 can be attached to the main body 210, and some of the components that make up the robot vacuum cleaner 200 can be housed inside the main body 210.

[0121] 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.

[0122] 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).

[0123] When viewed from above or below, the main body 210 can be formed into various shapes such as circles, ovals, or quadrilaterals.

[0124] The main body 210 can be divided into a lower main body and an upper main body. The lower main body and the upper main body can be combined to form a space inside.

[0125] The lower main body is 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.

[0126] The lower body may have an intake section 211 for air to flow in and a hole for accommodating a pair of wheels 260.

[0127] 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.

[0128] 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 arranged in the exhaust port.

[0129] 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.

[0130] The suction section 211 can rotatably accommodate the 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.

[0131] 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.

[0132] Although not illustrated, the robotic vacuum cleaner 200 of the present invention may include a bumper. The bumper is attached along the edge of the body 210 and is movable relative to the body 210.

[0133] 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 central side 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 or reducing the transmission of impact to the body 210.

[0134] The dust bin 220 can be configured to draw in external dust and air to store dust.

[0135] 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.

[0136] The dust bin 220 can be disposed inside the main body 210. In this case, the dust bin 220 can not only be fixedly attached to the main body 210, but also, according to the embodiment, can be detachably attached to the main body 210.

[0137] On the other hand, in this invention, a dust discharge path can be formed on 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.

[0138] On the other hand, the dust bin 220 of this embodiment may have a dust outlet 221 that communicates with the dust discharge 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.

[0139] 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 positioned to block 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.

[0140] With this configuration, when the dust collection motor 152 of the robotic vacuum cleaner base station 100 (described later) is running, the dust bin door 222 can be elastically deformed by the driving force of the dust collection motor 152. As the dust discharge port 221 opens, the dust in the dust bin 220 can be collected into the dust collection section 140 of the robotic vacuum cleaner base station 100.

[0141] The bucket 230 is formed as a container with an internal space to store liquids such as water inside. The bucket 230 can be arranged 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 detachable manner.

[0142] 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.

[0143] At this time, the supply unit 231 can be arranged on the opposite side of the sweeping robot 200 in the left-right direction relative to the dust discharge port 221. For example, if the dust discharge port 221 is arranged on the rear left side of the main body 210, then the supply unit 231 can be arranged on the rear right side of the main body 210.

[0144] 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.

[0145] On the other hand, the nozzle (not shown) is formed in a tubular or pipe-like shape and is connected to the bucket 230 so that the liquid inside the bucket 230 can flow through it. One side of the nozzle (not shown) is connected to the bucket 230, and the other end is located above a pair of rotating plates 241, so that the liquid inside the bucket 230 can be supplied to a pair of wiping cloths 242 respectively.

[0146] 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 rotating plate, and the end of the other tube of the branch can be located on the upper side of the right rotating plate.

[0147] 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, when 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.

[0148] The rotating cleaning unit 240 includes a rotating plate 241 and a cleaning cloth 242.

[0149] The rotating plate 241 can be configured as a pair, including a left rotating plate and a right rotating plate, and the wiping cloth 242 can be configured as a pair, including a left wiping cloth and a right wiping cloth.

[0150] The rotating plate 241 can be rotatably arranged on the bottom surface of the main body 210, and the rag 242 can be attached to the underside of the rotating plate 241.

[0151] 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 greater 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.

[0152] A pair of rotating plates 241 can achieve left-right symmetry.

[0153] The rag 242 can be attached to the underside of the rotating plate 241 so as to face the floor surface B.

[0154] The bottom surface of the rag 242 facing the floor has a specified 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 greater than its height in the vertical direction. When 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.

[0155] The bottom surface of the cleaning cloth 242 can be roughly circular, and the cleaning cloth 242 as a whole can be rotationally symmetrical. In addition, the cleaning cloth 242 is detachably mounted on 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.

[0156] 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.

[0157] 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.

[0158] On the other hand, the agitator 250 of this embodiment may be provided with an additional agitator motor (not shown) to receive rotational power. Of course, according to the embodiment, rotational power may also be received from the driving motor or from the drive unit of the rotating cleaning unit 240.

[0159] 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.

[0160] Wheel 260 can be installed on the main body 210 and can roll on the floor surface.

[0161] 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.

[0162] 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.

[0163] 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.

[0164] With this configuration, when the driving motor is running, the wheel 260 rotates, and the main body 210 can travel on the floor at a specified speed.

[0165] 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.

[0166] 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.

[0167] 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).

[0168] In addition, the battery can supply power to the sensor unit (not shown) and the control unit (not shown).

[0169] 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 arranged on the rear side of the outer side of the main body 210. When 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 to receive power.

[0170] 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.

[0171] Below, refer to Figure 10 and Figure 11 The sweeping robot base station 100 of the present invention will be described.

[0172] The robotic vacuum cleaner 200 can be housed in the robotic vacuum cleaner base station 100. The robotic vacuum cleaner 200 can be attached to the joint 120 of the robotic vacuum cleaner base station 100.

[0173] The robot vacuum cleaner base station 100 may include a cover 110.

[0174] 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 hexahedral-like shape including at least one outer wall surface.

[0175] The inside of the cover 110 can be formed with a space that can accommodate the joint 120, the dust collection flow path 130, the dust collection part 140, the dust collection motor 152, the cloth washing part 160, the cloth drying part 170, and the circulation flow path.

[0176] The cover 110 can be installed on the lower side of the kitchen cabinet 2. Specifically, the cover 110 can be installed in the installation space formed between the lower side panel 23 of the kitchen cabinet 2 and the kitchen floor.

[0177] The cover 110 includes a pair of outer walls 111 facing each other. The outer walls 111 may include surfaces formed along the direction of gravity. In this case, the outer walls 111 may be formed into a plate shape with a specified thickness, or, in order to reduce the overall weight, they may be configured into an assembly shape with a space inside.

[0178] One pair of outer walls 111 can be installed at a predetermined interval on the underside of the kitchen cabinet 2. At this time, the cover 110 also includes a bottom surface facing the kitchen floor, and the two pairs of outer walls can be connected through the bottom surface.

[0179] With this configuration, the components of the robot vacuum cleaner base station 100 can be accommodated inside the cover 110 (between a pair of outer walls 111).

[0180] Specifically, a drawer 190 may be arranged between a pair of outer walls 111. That is, a pair of outer walls 111 are arranged to face the side walls 191 of a pair of drawers, and a connecting part 120, a dust collection path 130, a dust collection part 140, a dust collection motor 152, a cloth washing part 160, a cloth drying part 170, and a circulation path part 180 may be arranged between the side walls 191 of a pair of drawers.

[0181] Drawer 190 will be explained later.

[0182] On the other hand, the cover 110 may also include a bottom surface facing the kitchen floor and an upper side surface 113 facing the lower side panel 23 of the kitchen cabinet 2 (see Figure 34). In addition, the cover 110 may also include a rear side surface connecting the bottom surface and the upper side surface.

[0183] With this configuration, the cover 110 can seal the upper and lower sides of the robot vacuum base station 100. Therefore, even if foreign objects fall from the kitchen cabinet 2 to the lower side, it can prevent the robot vacuum 200 and the components of the robot vacuum base station 100 from being contaminated.

[0184] Additionally, the robotic vacuum cleaner 200 can be housed inside the enclosure 110. The enclosure 110 can be arranged such that the distance between its outer walls 111 is greater than the maximum horizontal width of the robotic vacuum cleaner 200. With this configuration, the robotic vacuum cleaner 200 can enter and exit the enclosure 110.

[0185] In this embodiment, the robotic vacuum cleaner 200 can enter and exit from the front of the robotic vacuum cleaner base station 100. Here, "front" can refer to the direction in which the door 126 is provided with reference to the interior of the robotic vacuum cleaner base station 100.

[0186] Additionally, "rear" can refer to the opposite direction from the front, based on the interior of the robotic vacuum cleaner base station 100. For example, a building wall (not shown) may be arranged behind the robotic vacuum cleaner base station 100.

[0187] 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.

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

[0189] Therefore, the upper side of the cover 110 can be covered by the kitchen cabinet 2, and the lower side of the cover 110 can be covered by the kitchen floor. In addition, the left and right sides of the cover 110 are covered by the outer wall 111 and are arranged in the lower part of the kitchen cabinet 2. At this time, the lower part of the kitchen cabinet 2, except for the robot vacuum base station 100, is finished by the baseboard 26, so only the front of the cover 110 can be exposed to the outside.

[0190] This minimizes the degree to which the robot vacuum base station 100 and the robot vacuum 200 are exposed to the outside.

[0191] With this configuration, the robot vacuum cleaner base station 100 of the present invention has an aesthetic effect that can provide users with decoration.

[0192] On the other hand, in one embodiment of the present invention, the height of the upper end of the outer wall 111 may be lower than the height of the upper side surface 113 of the cover 110. Therefore, a height difference may occur between the upper end of the outer wall 111 and the upper side surface of the cover 110.

[0193] Therefore, a space can be formed between the upper end of the outer wall 111 and the upper side of the cover 110 for a water supply hose connected to the water supply pipe to pass through, a space can be formed for a drainage hose to pass through for wastewater generated after washing the rag 242, and a space can also be formed for a hose to pass through for water generated during the drying process of the rag 242. In addition, a space can be formed between the upper end of the outer wall 111 and the upper side of the cover 110 for a power cable to pass through for supplying power to the robot vacuum cleaner base station 100.

[0194] Therefore, according to the present invention, when the drawer 190 is extended, the hose and wire can be extended together with the drawer, thereby providing convenience for the user.

[0195] On the other hand, refer to Figure 23 The cover 110 of the present invention also includes a support 112 that can contact the kitchen cabinet 2.

[0196] The support member 112 is arranged between the kitchen floor and the lower side panel 23 of the kitchen cabinet 2, and can contact and support the kitchen floor and the lower side panel 23 of the kitchen cabinet 2. Thus, the space where the robot vacuum station 100 is installed can be maintained by supporting the lower side panel 23 of the kitchen cabinet 2.

[0197] The support member 112 is hinged to the outer wall 111. Specifically, the support member 112 is hinged to be able to rotate relative to the front end of the outer wall 111.

[0198] The support member 112 can close the front end of the outer wall 111, and the front end of the closed outer wall 111 can be opened by rotation.

[0199] The robot vacuum cleaner base station 100 may include a joint 120.

[0200] The robotic vacuum cleaner 200 and the robotic vacuum cleaner base station 100 can be physically connected, electrically connected, and / or connected via the joint 120.

[0201] The connecting part 120 can be arranged inside the cover 110. In this case, the connecting part 120 in this embodiment is configured to be able to be pulled out from the cover 110 via the drawer 190.

[0202] With the configuration described above, when the joint 120 needs cleaning, repair, or replacement of some parts, the user can easily pull out the joint 120 for management and maintenance.

[0203] An entrance 127 for the robotic vacuum cleaner 200 to enter can be formed in the joint 120. The entrance 127 may refer to the space formed in front of the robotic vacuum cleaner base station 100.

[0204] 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 bottom member 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.

[0205] 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 a dust collection section 140 and a 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.

[0206] 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 arranged at the upper end of the entrance / exit 127 and in a direction parallel to the bottom member 121. The door 126 may be hinged relative to the cover 110. Alternatively, the door 126 may be hinged relative to the side wall 124 of the joint 120. The door 126 may be rotated by a door drive unit 126a. As an example, the door drive unit 126a may be a motor.

[0207] 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.

[0208] Door 126 can remain closed at the entrance / exit 127 while the robot vacuum 200 is housed within the connecting portion 120. Furthermore, when the robot vacuum 200 begins to move from the connecting portion 120, the door can rotate to open the entrance / exit 127. Also, door 126 can rotate to close the entrance / exit 127 after the robot vacuum 200 has passed through it. Additionally, when the robot vacuum 200 approaches from outside the robot vacuum base station 100, door 126 can rotate to open the entrance / exit 127.

[0209] The joint 120 may include a receiving space S, a bottom member 121, a joint wall 123, and a side wall 124.

[0210] The robotic vacuum cleaner 200 can be accommodated in the accommodating space S of the connecting part 120. As one example, the accommodating space S can be the space surrounded by the bottom member 121, the connecting wall 123, and the side wall 124. As another example, the accommodating space S can be the space surrounded by the bottom member 121, the cleaning member 122, the connecting wall 123, and the side wall 124. As yet another example, the accommodating space S can be the space where the robotic vacuum cleaner 200 is located when it is connected to the power supply terminal 123b, or the space where the robotic vacuum cleaner 200 is located when its dustbin 220 is connected to the dust passage hole 123a.

[0211] The bottom component 121 may be configured to allow the robot vacuum base station 100 to contact the floor surface and to support the robot vacuum 200 when the robot vacuum base station 100 is combined with the robot vacuum 200. The bottom component 121 may include a bottom component body 121a, an inclined portion 121b, a wheel engagement portion 121c, and an agitator receiving portion 121d.

[0212] The bottom component body 121a can form the overall appearance of the bottom component 121. The bottom component body 121a may be provided with an inclined part 121b, a wheel engagement part 121c, and an agitator receiving part 121d.

[0213] The bottom component body 121a can be formed with a width (or diameter) in the horizontal direction (parallel to X and Y) greater than its 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.

[0214] A circulation path can be provided inside the bottom component body 121a. As a result, the air discharged from the dust collection motor 152 can flow through the circulation path formed inside the bottom component body 121a and be discharged from the exhaust port 125b.

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

[0216] The inclined section 121b may have an upward slope facing forward in the direction in which the robot vacuum cleaner 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, and may have a slope that slopes upward as it faces forward in the direction in which the robot vacuum cleaner 200 enters. In this case, "forward" in the direction in which the robot vacuum cleaner 200 enters refers to the rear side relative to the robot vacuum cleaner base station 100. As a result, the robot vacuum cleaner 200 can easily climb onto the robot vacuum cleaner base station 100 from the ground.

[0217] A wheel guide 121ba may be provided in the inclined section 121b.

[0218] The wheel guide portion 121ba can be formed in the shape of a groove 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 becomes narrower compared to the entrance as it moves forward along the climbing path of the robotic vacuum cleaner 200. 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.

[0219] An auxiliary wheel guide 121bb may be provided in the inclined section 121b.

[0220] The auxiliary wheel guide portion 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 portion 121bb can also be formed in a convex shape so that it contacts the auxiliary wheel 270 when the wheel 260 of the robotic vacuum cleaner 200 is placed on the wheel guide portion 121ba. Thus, when the robotic vacuum cleaner 200 moves on the tilting portion 121b, it is supported not only by the wheel 260 but also stably supported by the auxiliary wheel 270, thereby enabling stable movement.

[0221] 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. When the wheel 260 of the robotic vacuum cleaner 200 is mounted on 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 enable 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 steps. Thus, the robotic vacuum cleaner 200 can easily move to the wheel engagement portion 121c via the tilting portion 121b.

[0222] The wheel engagement portion 121c can be arranged at the stopping position of the left and right side wheels 260 of the sweeping robot 200 to ensure that the sweeping robot 200 stops in an accurate position. Here, the stopping position of the wheels 260 refers to a preset position for the sweeping robot 200 to stop in order to engage with the power supply terminal 123b and / or a preset position for the sweeping robot 200 to stop in order to connect the dust bin 220 with the dust passage hole 123a.

[0223] The shape of the wheel engagement portion 121c can be formed into an arc shape that corresponds 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 placed in the arc-shaped wheel engagement portion 121c.

[0224] The agitator 250 of the robotic vacuum cleaner 200 can be accommodated in the agitator accommodating portion 121d. Specifically, the agitator accommodating portion 121d can provide space to accommodate 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.

[0225] The agitator receiving portion 121d may include a recessed portion 121da and a protruding portion 121db.

[0226] The recess 121da can be formed to be recessed in the bottom member 121. The recess 121da can form a receiving space 121dc 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 121dc of the recess 121da.

[0227] The receiving space 121dc of the recess 121da can communicate with the receiving space S of the joint 120.

[0228] An exhaust port 125b may be formed on one side of the recess 121da. Specifically, the exhaust port 125b may be formed on the side of the recess 121da. Thus, air discharged from the dust collection motor 152 and passing through the circulation path can be discharged through the exhaust port 125b into the receiving space 121dc of the recess 121da.

[0229] The protrusion 121db can be formed to protrude from the bottom member 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 121dc of the recess 121da, the protrusion 121db can be arranged at a predetermined distance from the main body 210 of the sweeping robot 200.

[0230] The protrusion 121db can guide the air expelled through the exhaust port 125b to the suction section 211 of the robot vacuum cleaner 200. Thus, the air discharged into the receiving space 121dc of the recess 121da can be guided by the protrusion 121db to the suction section 211 of the robot vacuum cleaner 200.

[0231] 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 sweeping robot 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 bottom member body 121a or the bottom surface of the cover 110. Thus, the agitator 250 of the sweeping robot 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.

[0232] An exhaust port 125b may be formed in the agitator housing 121d. The exhaust port 125b may be formed on the side of the agitator housing 121d. The exhaust port 125b may connect the recess 121da of the agitator housing 121d and the dust collection motor 152 via a circulation flow path. The recess 121da of the agitator housing 121d and the circulation flow path may be connected through the exhaust port 125b. Thus, air discharged from the dust collection motor 152 may be discharged through the exhaust port 125b to the recess 121da of the agitator housing 121d.

[0233] The connecting wall 123 is configured to provide dust passage holes 123a, power supply terminals 123b, and water supply nozzles 123c for the robot vacuum base station 100. The connecting wall 123 can spatially separate the housing space S from the components of the robot vacuum base station 100.

[0234] The connecting wall 123 can extend in a direction intersecting with the bottom member 121. The connecting wall 123 can be a wall extending vertically. The connecting wall 123 can be formed corresponding to the shape of the robotic vacuum cleaner 200. For example, the connecting wall 123 can be formed as an arc shape with a predetermined radius. This configuration can surround the outline of the robotic vacuum cleaner 200, increasing the area of ​​the outer surface facing the robotic vacuum cleaner 200. Furthermore, it can stably support the robotic vacuum cleaner 200.

[0235] A dust passage hole 123a can be formed in the joint 120 to allow air from outside the cover 110 to flow inwards. Specifically, a dust passage hole 123a can be formed in the joint wall 123 of the joint 120 to allow air from outside the cover 110 to flow inwards. The dust passage hole 123a can communicate with the dust bin 220 of the robot vacuum cleaner 200. The dust passage hole 123a can communicate with the dust outlet 141b of the dust bin 220 of the robot vacuum cleaner 200. The dust passage hole 123a can be formed with a hole shape corresponding to the shape of the dust bin 220 so that dust from the dust bin 220 flows into the dust collection section 140. The dust passage hole 123a can be formed with a shape corresponding to the dust outlet 141b of the dust bin 220. The dust passage hole 123a can be formed to communicate with the dust collection flow path 130. Air drawn in from the dust passage hole 123a can flow through the dust collection flow path 130 and then be discharged through the exhaust section 125.

[0236] The power supply terminal 123b can supply power to the robotic vacuum cleaner 200 that is coupled to the connecting part 120. The power supply terminal 123b can contact and be electrically connected to the charging terminal 280 of the robotic vacuum cleaner 200. The power supply terminal 123b can be disposed in the connecting part 120. Specifically, the power supply terminal 123b can be disposed in the connecting wall 123. The power supply terminal 123b can be electrically connected to the robotic vacuum cleaner 200 coupled to the connecting wall 123. The power supply terminal 123b can supply power to the battery of the robotic vacuum cleaner 200 coupled to the connecting wall 123.

[0237] The robot vacuum cleaner base station 100 may also include a water supply nozzle 123c.

[0238] 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 160a of the kitchen cabinet 2 to the storage space inside the water tank 230 of the robotic vacuum cleaner 200.

[0239] The sidewall 124 is configured to spatially separate the receiving space S of the connecting part 120 and the components of the robot vacuum base station 100. A pair of sidewalls 124 can be arranged on the left and right sides of the bottom member 121. The sidewalls 124 can be connected to both ends of the connecting wall 123. The sidewalls 124 can extend on the left and right sides of the bottom member 121 in a direction intersecting the bottom member 121. Specifically, the sidewalls 124 can extend vertically on the left and right sides of the bottom member 121. The height of the sidewalls 124 can be configured to correspond to the height of the support leg 21. Specifically, the height of the sidewalls 124 can be configured to be the same as the height of the support leg 21.

[0240] On the other hand, various components such as a dust collection path 130, a dust collection unit 140, a dust collection motor 152, a detergent box 163, and a wastewater tank 164 can be arranged on the outer side of the side wall 124. Specifically, the space between the side wall 124 and the outer wall of the cover 110 can accommodate the dust collection unit 140, the detergent box 163, and the wastewater tank 164.

[0241] The dust collection unit 140 and the detergent dispenser 163 can be slidably separated from the space between the side wall 124 and the outer wall of the cover 110 (see figure). The left-right width of the dust collection unit 140 and the detergent dispenser 163 can be formed to correspond to the distance between the side wall 124 and the outer wall of the cover 110.

[0242] On the other hand, in one embodiment of the present invention, the bottom member 121 can be configured to extend from the connecting wall 123 and the side wall 124. That is, the bottom member 121 can be detachably connected to the connecting wall 123 and the side wall 124.

[0243] This will be explained later.

[0244] The joint 120 also includes a cleaning component 122.

[0245] The cleaning component 122 is a mop used for cleaning the robot vacuum cleaner 200 and can be placed in the cleaning tank 128. The cleaning component 122 can come into contact with the mop 242 when the robot vacuum cleaner 200 is engaged.

[0246] The cleaning member 122 may have protrusions 122a and drainage holes 122b. When the cleaning unit 240 of the robot vacuum cleaner 200 is driven by rotating the cleaning unit while the mop 242 is placed on the cleaning member 122, the mop 242 rotates. At this time, if the mop 242 rotates while cleaning water is supplied to the cleaning member, the mop 242 can be cleaned by rubbing against the stationary protrusions 122a.

[0247] Furthermore, the cleaning member 122 can be configured to slope downwards towards the center. As a result, the cleaning water flowing along the inclined cleaning member 122 can flow out through the drain hole 122b into the space formed between the cleaning member 122 and the cleaning tank 128 after cleaning the cloth 242.

[0248] The joint 120 also includes a cleaning tank 128.

[0249] The cleaning tank 128 is configured to house the cleaning member 122. The cleaning tank 128 is located below the cleaning member 122, and the cleaning member 122 is detachably attached to the cleaning tank 128. The cleaning tank 128 can be configured to correspond to the cleaning member 122 so that the cleaning member 122 can be inserted. The detailed configuration of the cleaning tank 128 will be described later.

[0250] Figure 12 and Figure 13 A side view of the dust collection unit of the robot vacuum cleaner base station, used to illustrate an embodiment of the present invention, is shown. Figure 14 A cross-sectional view of the dust collection flow path of a robotic vacuum cleaner base station used to illustrate an embodiment of the present invention is shown.

[0251] The following is for reference Figures 12 to 14 This describes the dust collection section 140, the dust collection module 150, and the dust collection flow path 130.

[0252] The dust collection unit 140 can collect dust from the dust bin 220 of the robotic vacuum cleaner 200. The dust collection unit 140 can be arranged inside the cover 110. The dust collection unit 140 can also be arranged on the outside of the joint 120. In this case, the receiving space S can be arranged on the inside of the joint 120.

[0253] The dust collection unit 140 may include a dust collection unit cover 141, a dust bag (not shown), a filter 142, and a dust collection unit drawer 144.

[0254] 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 collection unit drawer 144.

[0255] The dust collection unit cover 141 has a dust collection unit drawer 144 that can be pulled out and attached to the inside, and a dust bag (not shown) can be stored inside the dust collection unit 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 flow path 131 and the second flow path 132.

[0256] One side of the interior of the dust collection unit cover 141 can be connected to the first flow path 131, and the other side can be connected to the second flow path 132. In addition, when a dust bag (not shown) is attached to the dust collection unit cover 141, the dust bag (not shown) can be connected to the first flow path 131 inside the dust collection unit cover 141.

[0257] The dust bag (not shown) can refer to a dust collection bag used by the dust collection motor 152 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 unit cover 141. Thus, the dust bag (not shown) can be separated from the dust collection unit cover 141 and discarded, and a new dust bag (not shown) can be attached to the dust collection unit cover 141. That is, the dust bag (not shown) can be defined as a consumable part.

[0258] The dust bag (not shown) can be configured to increase in volume when suction is generated by the dust collection motor 152, thereby enabling it to contain dust.

[0259] Therefore, the dust bag (not shown) can be 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, based on its increased volume, can be a hexahedral shape corresponding to the shape of the dust collection unit cover 141.

[0260] In contrast, the dust bag (not shown) can be made of a non-permeable material. For example, the dust bag (not shown) may include a roll of plastic (not shown). With the configuration described above, when the dust bag (not shown) is sealed or joined, it is possible to prevent dust or odors collected inside the dust bag (not shown) from leaking to the outside of the dust bag (not shown). At this time, the dust bag (not shown) can be installed onto the dust collection unit cover 141 through a dust bag box (not shown). The dust bag (not shown) can also be replaced through the dust bag box as needed.

[0261] Filter 142 can be arranged between dust collection hood 141 and second flow path 132. Filter 142 can be arranged 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 flow path 132 via filter 142.

[0262] Filter 142 can be arranged between dust collection hood 141 and second flow path 132. Filter 142 can be arranged 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 flow path 132 via filter 142.

[0263] The dust collection drawer 144 can be combined to be pulled out from the dust collection cover 141, and the dust bag (not shown) can be accommodated inside the dust collection drawer 144.

[0264] At this time, refer to Figure 17 The dust collection drawer 144 includes a dust collection drawer body 144a, a handle 144d, and a drawer slide 144e.

[0265] The interior of the dust collection drawer body 144a can provide space for assembling a dust bag (not shown). For example, the dust collection 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 flow path 131 and the second flow path 132.

[0266] For example, the dust collection 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 collection drawer body 144a can be greater than the lower left and right width. That is, the interior of the dust collection drawer body 144a can be stepped. 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).

[0267] The upper side of the dust collection drawer body 144a can be connected to the first flow path 131 via the inlet 144b. The inlet 144b can be configured to guide air flowing in the first flow path 131 into the interior of the dust bag (not shown). The inlet 144b can connect the first flow path 131 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 interior of the dust bag (not shown) via the first flow path 131 and the inlet 144b.

[0268] The dust collection drawer 144 can communicate with the second flow path 132 through an outlet 144c formed on its lower side. The outlet 144c can be configured to guide air passing through the dust collection drawer 144 to the second flow path 132. The outlet 144c can be arranged at a different height from the inlet 144b. The outlet 144c can be arranged lower than the inlet 144b. The outlet 144c can connect the internal space of the dust collection drawer 144 to the second flow path 132. Thus, air that has passed through a dust bag (not shown) and been filtered of dust can move to the second flow path 132 via the outlet 144c.

[0269] A handle 144d may be provided on the front of the dust collection section 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 joints hinged to the front surface of the dust collection section drawer body 144a and a gripping portion formed to connect the pair of joints for the user to grip.

[0270] With this configuration, when the user grasps the grip and pulls forward, the dust collection drawer body 144a can be pulled forward and drawn out together. Thus, according to the present invention, the user can easily grasp and pull the dust collection drawer 144 forward, and then lift the dust bag (not shown) upward to remove and replace it.

[0271] Drawer slides 144e can be formed on the left and right sides of the dust collection unit drawer body 144a. The drawer slides 144e can guide the movement of the dust collection unit drawer body 144a.

[0272] For example, the drawer slide 144e can be formed in the shape of a groove or rib on the left and right sides of the dust collection section drawer body 144a along the front and back directions.

[0273] With the configuration described above, when the user attaches the dust collection drawer 144 to the dust collection cover 141, it can be attached to the correct position, and the dust collection section 140, the first flow path 131, and the second flow path 132 can be connected to the correct position, thereby reducing flow loss.

[0274] 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 141c of the dust collection cover 141 may 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 141c of the dust collection cover 141 may be formed in a rib or a protruding step shape.

[0275] The robot vacuum cleaner base station 100 may include a dust collection flow path 130. The dust collection flow path 130 may refer to the flow path through which air drawn in by dust through the hole 123a flows through the dust collection section 140 to the dust collection motor 152.

[0276] Specifically, the dust collection flow path 130 may include: a first flow path 131, which connects the dust bin 220 and the dust collection section 140 when the robot vacuum 200 is connected to 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 flow path 132, which connects the dust collection section 140 and the dust collection motor 152.

[0277] On the other hand, in this specification, the first flow path 131 may also be referred to as the suction flow path 131. Hereinafter, both the first flow path 131 and the suction flow path 131 will be referred to as the first flow path 131 for ease of explanation.

[0278] The first flow path 131 can connect the dustbin 220 and the dust collection section 140 of the robotic vacuum cleaner 200. The first flow path 131 allows communication between the dustbin 220 and the dust collection section 140 of the robotic vacuum cleaner 200. The first flow path 131 can connect the dust passage hole 123a of the connecting part 120 and the dust collection section 140. The first flow path 131 can refer to the space between the dustbin 220 and the dust collection section 140 of the robotic vacuum cleaner 200. The first flow path 131 can be formed in a near-horizontal direction. The first flow path 131 can be a space formed rearward from the dust passage hole 123a, or a flow path that bends laterally from the dust passage hole 123a and allows dust and air to flow. Through the first flow path 131, dust in the dustbin 220 of the robotic vacuum cleaner 200 can move towards the dust collection section 140.

[0279] The second flow path 132 can connect the dust collection unit 140 and the dust collection motor 152. The second flow path 132 can be formed in a near-horizontal direction. In this case, the first flow path 132 and the second flow path 131 can be formed at different heights. The first flow path 131 and the second flow path 132 can be formed in a stacked structure. The second flow path 132 can be arranged lower than the first flow path 131. With the configuration described above, the lateral width and overall volume of the robotic vacuum cleaner base station 100 can be minimized.

[0280] The dust collection module 150 can provide suction airflow to the dust collection flow path 130.

[0281] Specifically, the dust collection module 150 may include a dust collection motor cover 151 and a dust collection motor 152.

[0282] The dust collection motor cover 151 can be arranged inside the cover 110. The dust collection motor cover 151 can house the dust collection motor 152 inside.

[0283] An inlet hole and an outlet hole can be formed on the dust collection motor cover 151.

[0284] The internal space of the dust collection motor housing 151 can be connected to the second flow path 132 through an inlet hole. Thus, the inlet hole can guide the air flowing in the second flow path 132 to the dust collection motor 152.

[0285] The internal space of the dust collection motor housing 151 can be connected to the circulation path through the discharge port. Thus, the discharge port can guide the air that has passed through the dust collection motor 152 to the circulation path.

[0286] The dust collection motor 152 can generate suction in the dust collection flow path 130. The dust collection motor 152 can be arranged inside the dust collection motor housing 151.

[0287] The dust collection motor 152 can be arranged behind the dust collection section 140. Thus, the dust collection motor 152 can provide suction power to suck up dust from the dust bin 220 of the robot vacuum cleaner 200.

[0288] The dust collection motor 152 can generate suction by rotating. As an example, the dust collection motor 152 can be formed into an approximately cylindrical shape.

[0289] One side of the dust collection motor 152 can be connected to the second flow path 132, and the other side can be connected to the circulation flow path. When the dust collection motor 152 is driven, the air flowing in the second flow path 132 can flow into the interior of the dust collection motor housing 151 through the inlet hole. Furthermore, the air flowing into the interior of the dust collection motor housing 151 can be discharged through the outlet hole after passing through the dust collection motor 152. Additionally, the air discharged through the outlet hole can flow in the circulation flow path and be discharged from the exhaust port 125b.

[0290] On the other hand, the rotation axis of the dust collection motor 152 can be formed in a near-horizontal direction. Furthermore, the inlet and outlet of the dust collection motor housing 151 can also be open in a horizontal direction. Additionally, the outlet can be located at the same height as the exhaust port 125b. With the configuration described above, the overall volume of the robotic vacuum cleaner base station 100, arranged in the installation space of the kitchen cabinet 2 or a structure, can be minimized.

[0291] The exhaust section 125 can direct the air discharged from the dust collection motor 152 to the outside of the enclosure 110. The exhaust section 125 can connect the internal space and the external space of the enclosure 110.

[0292] The exhaust section 125 may consist of a circulation path and an exhaust port 125b.

[0293] The circulation path can provide a flow path for the air discharged from the dust collection motor 152. The circulation path can be arranged inside the bottom component body 121a.

[0294] The circulation path can be connected to the flow path of the dust collection motor 152. The circulation path can refer to the flow path connecting the discharge port and the exhaust port 125b. One end of the circulation path can communicate with the internal space of the dust collection motor housing 151, and the other end of the circulation path can communicate with the receiving space 121dc of the recess 121da. Specifically, one end of the circulation path can be connected to the discharge port, and the other end of the circulation path can be connected to the exhaust port 125b.

[0295] The circulation path can be a horizontally formed path inside the housing 110. The circulation path can be connected to the flow path of the dust collection motor 152. Specifically, one end of the circulation path can be connected to the dust collection section 140, and the other end of the circulation path can be connected to the exhaust port 125b.

[0296] The exhaust port 125b serves as an outlet for guiding the air discharged from the dust collection motor 152 to the receiving space 121dc of the recess 121da. Thus, the air discharged from the dust collection motor 152 and flowing in the circulation path can be discharged to the outside of the housing 110 through the exhaust port 125b.

[0297] The vent 125b may be formed on the bottom member 121. The vent 125b may be formed on the agitator housing 121d. The vent 125b may be formed on the recess 121da of the agitator housing 121d. The vent 125b may be formed on the side of the recess 121da.

[0298] The circulating flow path of this embodiment of the invention can guide the air discharged from the dust collection motor 152 to the suction section 211 of the sweeping robot 200.

[0299] The circulating flow path guides the air expelled from the dust collection motor 152 to the suction section 211 of the robot vacuum 200 instead of expelling it to the outside, thereby creating a structure that allows air to continuously 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 152 is not discharged into the installation space of the kitchen cabinet 2, but instead flows back into the interior of the robot vacuum 200 and forms a circulating flow path, thus preventing damage to the interior of the kitchen cabinet 2.

[0300] The circulation path can refer to the space between the exhaust port 125b of the robot vacuum base station 100 and the suction section 211 of the robot vacuum 200. The circulation path can also refer to the recess 121da of the agitator housing 121d. Finally, the circulation path can refer to a connecting pipe (not shown) that is connected at one end to the suction section 211 of the robot vacuum 200 and at the other end to the exhaust port 125b of the robot vacuum base station 100.

[0301] Air passing through the dust collection motor 152 can be discharged into the receiving space S through the exhaust port 125b. The air discharged into the receiving space S can flow back into the suction section 211 due to the suction force of the dust collection motor 152. Thus, the air drawn from the dust bin 220 by the suction force of the dust collection motor 152 can sequentially pass through the dust passage 123a, the first flow path 131, the dust collection section 140, the second flow path 132, the dust collection motor 152, the circulation flow path, and the exhaust port 125b before being discharged into the receiving space S.

[0302] If the dustbin 220 of the robotic vacuum cleaner 200 and the suction section 211 of the robotic vacuum cleaner base station 100 are connected, the dust collection motor 152 can be driven, and air can be drawn in through the suction section 211 of the robotic vacuum cleaner 200. In addition, since the agitator 250 is housed inside the suction section 211, air discharged from the dust collection motor 152 and exhausted from the exhaust port 125b can be drawn into the suction section 211 of the robotic vacuum cleaner 200 under the action of the dust collection motor 152.

[0303] At this time, the dust collection motor 152 can be driven together with the suction motor (not shown) of the robot vacuum cleaner 200. Since the air discharged through the exhaust port 125b is sucked into the suction unit 211 by the suction force of the suction motor (not shown) in addition to the dust collection motor 152, it has the effect of improving dust collection efficiency.

[0304] Figure 15 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 16 An enlarged view of the cleaning water discharge section of the mop cleaning unit of the robot vacuum cleaner base station, used to illustrate an embodiment of the present invention, is shown. Figure 17 A diagram is shown illustrating the state of the dust collection unit and detergent dispenser in the base station of a sweeping robot according to an embodiment of the present invention.

[0305] Below, refer to Figures 15 to 17 The cleaning unit 160 of the robot vacuum cleaner base station 100 according to an embodiment of the present invention will be described.

[0306] The robot 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 robot vacuum cleaner 200 that is attached to the connecting part 120.

[0307] The rag cleaning unit 160 may include a cleaning water dispensing unit 161 that dispenses cleaning water to the cleaning member 122, a detergent box 163 that stores liquid containing detergent, and a wastewater tank 164 that stores the cleaning water generated after the rag 242 has been cleaned.

[0308] In the cleaning water discharge section 161, cleaning water for cleaning the rag 242 can be generated by mixing clean water and detergent.

[0309] A pair of cleaning water outlets 161 can be provided, with the pair of cleaning water outlets 161 arranged at intervals on the rear side of the connecting wall 123. The cleaning water outlets 161 can discharge cleaning water laterally onto the cleaning member 122 from both ends. At this time, the clean water supplied from the water supply pipe 160a of the kitchen cabinet 2 and passing through the regulator 162 can be branched to both sides through the branch flow path 161a and connected to the various cleaning water outlets 161 arranged at intervals. That is, the branch flow path 161a can be formed in the form of one pipe branching into two pipes. At this time, the end of any one of the branched pipes can be connected to any one of the pair of cleaning water outlets 161, and the end of the other branched pipe can be connected to the remaining one of the pair of cleaning water outlets 161.

[0310] The cleaning water discharge part 161 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.

[0311] The cleaning water discharge section 161 may have a clean water inlet 161b, a detergent inlet 161c, and a cleaning water outlet (not shown).

[0312] The purified water inlet 161b is configured to guide purified water supplied from the water supply pipe 160a of the kitchen cabinet 2 to the cleaning water outlet 161. Specifically, the water supply pipe 160a of the kitchen cabinet 2 is connected to a regulator 162, thereby allowing adjustment of the flow rate supplied from the water supply pipe 160a. In addition, a portion of the purified water after passing through 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 through the purified water inlet 161b into a pair of cleaning water outlets 161 arranged at intervals.

[0313] The detergent inlet 161c is configured to guide the detergent-containing liquid supplied from the detergent dispenser 163 to the cleaning water outlet 161. Specifically, a pump (not shown) can be used to supply the detergent-containing liquid stored in the detergent dispenser 163 to the cleaning water outlet 161.

[0314] Additionally, the detergent and purified water flowing into the cleaning water outlet 161 can be mixed and used as cleaning water. The cleaning water outlet 161 can discharge the cleaning water to the top surface of the cleaning member 122 through the cleaning water outlet. The cleaning water outlet can be formed on the bottom surface of the cleaning water outlet 161. The cleaning water outlet can be open in a direction opposite to the top surface of the cloth 242 placed on the cleaning member 122.

[0315] Detergent container 163 can store liquid containing detergent.

[0316] The detergent dispenser 163 includes a detergent dispenser body 163a, a handle 163b, and a detergent dispenser guide rail 163c.

[0317] 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 cleaning water dispensing part 161.

[0318] 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 joints hinged to the front surface of the detergent dispenser body 163a and a gripping portion formed to connect the pair of joints so that the user can grip it.

[0319] With this configuration, when the user grasps the grip and pulls forward, the detergent dispenser body 163a can also be pulled forward and extracted. Therefore, according to the present invention, the user can easily pull the detergent dispenser 163 forward to dispense detergent.

[0320] 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.

[0321] 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.

[0322] 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 during cleaning can be prevented.

[0323] 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.

[0324] The wastewater tank 164 provides space for storing the cleaning water generated after washing the cloth 242. The cleaning water discharged onto the upper surface of the cleaning member 122 can descend along the inclined surface of the cleaning member 122 and drain out through the drain hole 122b after the cloth 242 has been washed. The cleaning water passing through the drain hole 122b accumulates between the washing tank 128 and the cleaning member 122. Additionally, the cleaning water accumulated between the washing tank 128 and the cleaning member 122 can flow into the wastewater tank 164 through the pump flow path 164b.

[0325] The cleaning water stored in the wastewater tank 164 can be discharged to the drain pipe 25 of the kitchen cabinet 2 through the drain passage 164a. One end of the drain 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 cleaning water stored in the wastewater tank 164 can be discharged to the drain pipe by using a centrifugal pump (not shown) through the drain passage 164a.

[0326] The drainage path 164a connected to the wastewater 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 drainage 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 drainage path 164a.

[0327] 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 drain path 164a. The check valve may be located at the other end of the drain path 164a connected to the drain pipe 25.

[0328] On the other hand, the detergent dispenser 163 and the wastewater tank 164 can be accommodated in the space formed between the side wall 124 and the outer wall 111 of the enclosure. The detergent dispenser 163 can be arranged on the lower side of the space between the side wall 124 and the outer wall 111 of the enclosure, and the wastewater tank 164 can be arranged on the upper side of the detergent dispenser 163 in the space between the side wall 124 and the outer wall 111 of the enclosure.

[0329] On the other hand, in the cloth cleaning unit 160 of the present invention, the cleaning groove 128 is detachably connected. That is, in one embodiment of the present invention, the cleaning groove 128 is configured to be able to extend out from the cloth cleaning unit 160. The structure of the cloth cleaning unit 160 connected with the cleaning groove 128 will be described later.

[0330] Figure 18A 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 19 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 20 A cross-sectional view is shown to illustrate the state of air flowing into the hot gas supply module according to an embodiment of the present invention.

[0331] Reference Figures 18 to 20 In one embodiment of the present invention, the robot vacuum cleaner base station 100 may include a cloth drying unit 170. At this time, the cloth drying unit 170 can dry the cloth 242 of the robot vacuum cleaner 200 after it has been cleaned by the cloth washing unit 160 or the cloth 242 that is wet after the wet cleaning operation is completed.

[0332] The cloth drying unit 170 of this embodiment may include a hot air supply module 171, a steam exhaust pipe 172, an exhaust fan 173, and a check valve (not shown).

[0333] The hot air supply module 171 can supply hot air to the accommodating space S and may include a connecting flow path 171a, a blower fan (not shown), and a heater 171d.

[0334] The connecting flow path 171a can connect the external space of the enclosure 110 and the containing space S. The air inlet 171b of the connecting flow path 171a can communicate with the external space, and the air outlet 171c of the connecting flow path 171a can communicate with the containing space S.

[0335] An air inlet 171b connecting the flow path 171a can be formed on the rear side of the cover 110.

[0336] An air outlet 171c connecting the flow path 171a can be arranged on the upper side of the cleaning member 122. The air outlet 171c can be open in a direction opposite to the cleaning member 122. A pair of air outlets 171c can be provided in a downward-opening state.

[0337] The air outlet 171c can open towards the upper side of the mop 242 when the mop 242 is placed on the cleaning member 122. The air outlet 171c can also be located adjacent to the mop 242 when the mop 242 is placed on the cleaning member 122, and open downwards to allow the exhausted air to flow towards the mop 242. The air outlet 171c can also open in a direction opposite to the mop 242 when the robot vacuum cleaner 200 is engaged with the connecting part 120.

[0338] An air supply fan (not shown) can be arranged on the connecting flow path 171a and blow air into the receiving space S. When the air supply fan (not shown) is driven, the air flowing in through the air inlet 171b can be heated by the heater 171d and discharged into the receiving space S through the air outlet 171c.

[0339] The heater 171d can be arranged on the connecting flow path 171a and can heat the air flowing on the connecting flow path 171a. The heater 171d can heat the air discharged through the air outlet 171c. Although the heater 171d can be arranged on the connecting flow path 171a, it can also be arranged at the air outlet 171c instead. That is, the specific shape or arrangement of the heater 171d is not limited, as long as it can heat the air discharged into the accommodating space S.

[0340] The heater 171d may include a heater housing 171da and a heating element (not shown). The heater housing 110 may be arranged on the connecting flow path 171a, and the interior of the heater housing may have a space capable of accommodating the heater 171d. The heating element can heat the external air flowing into the interior of the heater housing 110. Thus, the air heated by the heating element can be discharged into the accommodating space S through the air outlet 171c, thereby drying the wet cloth 242.

[0341] The steam exhaust pipe 172 can discharge the hot and humid air generated in the containment space S during the drying of the dishcloth 242 to the drain pipe 25. The steam exhaust pipe 172 can be connected to the containment space S and the drain pipe 25 of the kitchen cabinet 2.

[0342] One end of the steam exhaust pipe 172 can be connected to the receiving space S, and the other end can be connected to the drain pipe 25. Specifically, the air inlet 172a, which is one end of the steam exhaust pipe 172, can be connected to the receiving space S, while the air outlet (not shown), which is the other end, can be connected to the drain pipe 25.

[0343] The steam exhaust pipe 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, if the steam exhaust pipe 172 is connected to the upstream 25b based on the U-bend 25a of the drain pipe 25, the hot air discharged through the steam exhaust pipe 172 may not be able to pass through the drain pipe 25 due to the water accumulated in the U-bend 25a.

[0344] On the other hand, the steam exhaust pipe 172 can branch into two pipes inside the shroud 110 and penetrate both sides of the shroud 110. In this case, either branch pipe can penetrate the left outer wall of the shroud 110, and the other branch pipe can penetrate the right outer wall of the shroud 110. The steam exhaust pipes 172 penetrating the outer walls 111 of both sides of the shroud 110 can be connected to the drain pipe 25. Thus, the steam drawn into the containment space S from the steam exhaust pipe 172 can flow along the branching steam exhaust pipes 172 and be discharged downstream 25c of the U-shaped bend 25a of the drain pipe 25.

[0345] The exhaust fan 173 can discharge air from the containment space S to the drain pipe 25 via the steam exhaust pipe 172. The exhaust fan 173 can generate airflow along the steam exhaust pipe 172. The exhaust fan 173 can be arranged on the steam exhaust pipe 172.

[0346] When the exhaust fan 173 is driven, air in the containment space S can flow in from the air inlet 172a. The air flowing in from the air inlet 172a can flow along the steam exhaust pipe 172 and be discharged towards the drain pipe 25. Specifically, when the exhaust fan 173 is driven, the air flowing along the steam exhaust pipe 172 can be discharged downstream 25c relative to the U-bend 25a of the drain pipe 25.

[0347] The cloth drying unit 170 may include a check valve (not shown). The check valve prevents fluid inside the drain pipe 25 from flowing back into the steam discharge pipe 172. The check valve may be located at the other end of the steam discharge pipe 172 that is connected to the drain pipe 25.

[0348] Figure 21 and Figure 22 A diagram is shown illustrating the arrangement of the base station of the sweeping robot on a horizontal plane in an embodiment of the present invention.

[0349] Reference Figure 4 , Figure 21 as well as Figure 22 The arrangement of the robot vacuum cleaner base station 100 according to an embodiment of the present invention will be described.

[0350] 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.

[0351] Therefore, the robot vacuum cleaner base station 100 of this embodiment is characterized in that it is arranged horizontally in a way that matches the space formed between the lower side panel 23 of the kitchen cabinet 2 and the kitchen floor.

[0352] 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 arranged on the side of the entrance 127.

[0353] At this time, when both the dust collection unit 140 and the cloth cleaning unit 160 are provided, the connecting part 120 can be arranged between the dust collection unit 140 and the cloth cleaning unit 160.

[0354] For example, an entrance / exit 127 and a door 126 can be arranged in front of the robot vacuum base station 100. Furthermore, a connecting part 120 for the robot vacuum 200 to connect can be arranged rearward from the entrance / exit 127. In this case, the dust collection part 140 can be arranged at a position extending a predetermined length from the front end of the robot vacuum base station 100 to the rear. Additionally, the mop cleaning part 160 can also be arranged at a position extending a predetermined length from the front end of the robot vacuum base station 100 to the rear.

[0355] 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.

[0356] At this time, the dust bag (not shown) of the dust collection unit 140 can be configured to be pulled out to the front of the cover 110. In addition, the detergent box 163 of the cloth washing unit 160 can be configured to be pulled out to the front of the cover.

[0357] 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 for the user to pull out the detergent box 163.

[0358] With the configuration described above, when a user attempts to pull out the dust bag (not shown) or detergent dispenser 163, the pull-out position can be immediately identified, and the dust bag (not shown) or detergent dispenser 163 can be pulled out with the simple action of pulling the handle, thus providing convenience.

[0359] On the other hand, the rear ends of the dust collection section 140 and the cloth cleaning section 160 can be arranged at a predetermined distance from the rear end of the cover 110. Furthermore, a dust collection motor 152 can be arranged between the rear end of the cover 110 and the rear end of the dust collection section 140. This configuration allows for easy connection of the power supply wire to the dust collection motor 152. Additionally, it minimizes the overall space occupied by the connecting section 120, the dust collection section 140, and the dust collection motor 152 within a limited space.

[0360] Furthermore, between the rear end of the cover 110 and the rear end of the cloth washing section 160, a flow path for the washing water to flow through the cloth 242 and a pump to provide the flow force for the washing water can be arranged at least partially. With the configuration described above, the path of the washing water flowing in from the water supply pipe 160a can be minimized. Additionally, it has the effect of minimizing the overall space occupied by the joint 120, the cloth washing section 160, and the flow path for the washing water within a limited space.

[0361] On the other hand, in the robot vacuum cleaner base station 100, the cloth drying unit 170 can be arranged further rearward than the connecting part 120. In this case, the cloth drying unit 170 can be arranged between the rear end of the connecting part 120 and the rear end of the cover 110.

[0362] Therefore, in the robot vacuum cleaner base station 100 of this embodiment, a dust collection part 140 and a cloth washing part 160 can be arranged on the left and right sides with the joint part 120 as the reference, and a cloth drying part 170 can be arranged on the rear side.

[0363] That is, in the robot vacuum cleaner base station 100 of the present invention, a dust collection unit 140, a cloth washing unit 160 and a cloth drying unit 170 can be provided simultaneously within a specified distance range from the outer contour of the joint 120.

[0364] This arrangement allows for the simultaneous arrangement of the joint 120, dust collection section 140, cloth washing section 160, and cloth drying section 170 within the narrowest possible space on a horizontal plane.

[0365] This shorter distance between the dust bin 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 containing the washing water and wastewater after washing is effectively limited.

[0366] Furthermore, with this arrangement, the robot vacuum cleaner base station 100 of the present invention can arrange all its constituent components within a limited height.

[0367] Specifically, based on the state where the robot vacuum 200 is engaged with the engagement portion 120, at least a portion of the dust collection portion 140 can be arranged lower than the uppermost point of the robot vacuum 200. Additionally, at least a portion of the mop cleaning portion 160 can be arranged lower than the uppermost point of the robot vacuum 200. Furthermore, at least a portion of the mop cleaning portion 160 can be arranged to be lower than the uppermost point of the dust collection portion 140.

[0368] Furthermore, based on the state where the robot vacuum cleaner 200 is engaged with the engagement part 120, the top of the robot vacuum cleaner 200 can be positioned higher than the dust bag (not shown). Additionally, the top of the robot vacuum cleaner 200 can be positioned higher than the detergent dispenser 163. Furthermore, the top of the dust bag (not shown) can be positioned higher than the detergent dispenser 163.

[0369] From another perspective, when the robot vacuum cleaner 200 is engaged with the engagement part 120, and an imaginary plane H parallel to the kitchen floor is drawn with the robot vacuum cleaner 200, the dust collection part 140, the cloth washing part 160, and the cloth drying part 170 can all pass through it. This means that all the components can be arranged within a specified height range.

[0370] From another perspective, when the robotic vacuum cleaner 200 is engaged with the connecting part 120, the connecting part 120 can be divided into three areas along the vertical direction. At this time, the connecting part 120 can include: a first area (the space between B and H1), which is located at the same horizontal level as the detergent dispenser 163; a second area (the space between H1 and H2), which is arranged above the first area and is located at the same horizontal level as at least a portion of the dust bag (not shown); and a third area (the space between H2 and H3), which is arranged above the second area. At this time, the dust bag (not shown) and the detergent dispenser 163 can be arranged simultaneously on the left and right sides of the first area, the dust bag (not shown) and the wastewater tank 164 can be arranged on the left and right sides of the second area, and only the upper part of the robotic vacuum cleaner 200 can be arranged in the third area.

[0371] 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 joint 120. This arrangement has the following effects: 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.

[0372] On the other hand, when the charging station for the robot vacuum cleaner is located in the lower part of the kitchen cabinet, a decorative effect can be achieved by minimizing external exposure. However, if the robot vacuum cleaner malfunctions while it is inside the lower part of the kitchen cabinet, or if the charging station itself malfunctions, it becomes difficult for the user to remove it for repair. To solve this problem, in this invention, a drawer 190 can be added to the robot vacuum cleaner base station 100.

[0373] Figure 23A diagram is shown illustrating the state in which a drawer is provided in the base station of a sweeping robot according to an embodiment of the present invention. Figure 24 A diagram is shown illustrating the state in which the drawer of the robot vacuum cleaner base station is extended, according to an embodiment of the present invention.

[0374] The following is for reference Figure 23 and Figure 24 This describes the drawer 190 of a robotic vacuum cleaner base station 100 according to an embodiment of the present invention.

[0375] 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.

[0376] With drawer 190 inserted into cover 110, if robot vacuum 200 enters joint 120, door 126 can be closed. In this case, robot vacuum 200 is blocked from the inside and outside of cover 110 by door 126.

[0377] Therefore, during the dust collection process of the vacuum cleaner 200's dust bin 220 inside the housing 110, dust can be prevented from scattering to the outside of the vacuum cleaner base station 100. Additionally, during the washing of the mop 242, wastewater can be prevented from leaking to the outside of the vacuum cleaner base station 100.

[0378] Drawer 190 can move relative to cover 110. For example, cover 110 can be fixedly attached to kitchen cabinet 2, and drawer 190 can be extended forward from cover 110.

[0379] At this time, drawer 190 can be extended with the connecting part 120 provided inside. With this configuration, if drawer 190 is extended, the connecting part 120 and / or the robot vacuum cleaner 200 can be extended from the kitchen cabinet 2 to the outside.

[0380] At this time, with the door 126 closing the entrance 127, if the drawer 190 is pulled out from the cover 110, the robot vacuum cleaner 200 arranged in the joint 120 can be exposed to the outside.

[0381] Therefore, according to this embodiment, when maintenance such as repair or cleaning of the robot vacuum base station 100 is required, the user can easily pull out the connecting 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.

[0382] On the other hand, in one embodiment of the present invention, the drawer 190 can be drawn out with a dust collection section 140 provided inside. That is, the drawer 190 can be drawn out together with the dust collection section 140.

[0383] On the other hand, 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 collection unit drawer 144 can be parallel to the drawing direction of the drawer 190.

[0384] 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 disposed of internally. 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.

[0385] On the other hand, the wastewater tank 164 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 wastewater tank 164 is drawn out can be parallel to the direction in which the drawer 190 is drawn out.

[0386] With this configuration, in a sweeping robot base station 100 of an embodiment of the present invention, the drawer 190, the dust collection part 140 and the wastewater tank 164 can all be drawn out in parallel directions.

[0387] Therefore, it allows users to easily identify the lead-out directions of the plurality of constituent elements of the robotic vacuum cleaner base station 100 of the present invention, and to easily lead out, repair and maintain them.

[0388] Drawer 190 includes drawer sidewalls 191, fittings 192, and drawer slides 193.

[0389] The drawer sidewalls 191 are configured to move relative to each other between themselves and the outer wall of the cover 110. For example, a pair of drawer sidewalls 191 may be arranged to face one pair of outer walls 111 of the cover 110.

[0390] On the other hand, in this invention, the height of the upper end of the drawer side wall 191 is higher than the height of the upper end of the outer wall 111. That is, a height difference may occur between the upper end of the drawer side wall 191 and the upper end of the outer wall 111. This height difference h provides space for the accessory part 192, which will be described later, to move.

[0391] At this time, the pair of drawer sidewalls 191 can be positioned closer to the inner side of the robot vacuum base station 100 than the pair of outer walls 111 of the cover 110. That is, the pair of drawer sidewalls 191 can be positioned closer to the joint 120 than the pair of outer walls 111 of the cover 110. At this time, the pair of drawer sidewalls 191 can have a larger spacing than the maximum horizontal width of the robot vacuum 200.

[0392] At this time, a pair of drawer sidewalls 191 can be directly connected to the bottom member 121 of the connecting part 120. In contrast, a pair of drawer sidewalls 191 can be connected by a drawer base (not shown), and the connecting part 120 can also be connected to the upper side of the drawer base (not shown) and move together.

[0393] 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 connecting part 120. That is, based on the state in which the robot vacuum cleaner 200 is connected to the connecting part 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.

[0394] This configuration allows for the arrangement of the dust collection unit 140 and the cloth washing unit 160 using minimal horizontal space.

[0395] A fitting part 192 is disposed on the drawer side wall 191, and at least one of a hose and a wire is detachably connected to the fitting part 192. For example, the fitting part 192 is arranged on the drawer side wall 191, and a hose and / or wire can be connected to the fitting part 192.

[0396] The accessory part 192 is attached to the drawer side wall 191. One side of the accessory 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 accessory part 192 is located on the outer side of the drawer side wall 191.

[0397] At least one of the hose and the wire is detachably connected to the fitting part 192. For example, at least one of the following can be detachably connected to the fitting part 192: a water supply pipe connection that is connected to the water supply pipe, a drain pipe connection that is connected to the water supply and drain pipes, an exhaust pipe connection that is connected to the steam exhaust pipe that supplies air to the inside of the drawer 190, and a power supply connection that supplies power.

[0398] At this time, the water supply pipes for the rag washing unit 160 and the water supply pipes connected to an external water source can be connected to both sides of the water supply pipe connection. In addition, the drain pipes for the rag washing unit 160 and the drain pipes connected to the upstream 25b of the U-shaped bend of the kitchen cabinet 2 can be connected to both sides of the drain pipe connection.

[0399] That is, the accessory part 192 of the present invention can be a structure in which the water supply pipe and the drain pipe that directly drain water using the water supply and drain pipe provided in the kitchen cabinet 2 are detachably connected to the water supply and drain pipe inside the robot vacuum base station 100.

[0400] In addition, steam exhaust pipes connected to the air outlet 171c of the cloth drying section 170 and the downstream steam exhaust pipe connected to the U-shaped bend of the kitchen cabinet 2 can be respectively connected to the two sides of the exhaust pipe connection.

[0401] Therefore, the air discharged from the cloth drying section 170 can be discharged downstream 25c of the U-shaped bend.

[0402] Additionally, the power connection section can be equipped with a wire for connecting to an external power source. In this case, the wire can be directly connected to the power connection section, or a connector or adapter can be used to connect the wire.

[0403] In this case, in terms of height, the fitting part 192 can be arranged between the upper end of the drawer side wall 191 and the upper end of the outer wall 111. Alternatively, the fitting part 192 can be arranged between the upper end of the support member 112 and the upper end of the outer wall 111.

[0404] With this configuration, during the process of drawing out the drawer 190, the fitting part 192 moves together with the drawer side wall 191. During the process of drawing out the fitting part 192, it moves linearly on the upper side, which is higher than the upper end of the outer wall 111, thus preventing interference between the fitting part 192 and the outer wall 111.

[0405] However, the fitting part 192 can be arranged to be lower than the upper end of the support member 112. That is, in terms of height, the fitting part 192 can be arranged between the upper end of the support member 112 and the upper end of the outer wall 111.

[0406] This is because the upper end of the support 112 should be at a height that allows it to contact the lower side panel 23 of the kitchen cabinet 2.

[0407] In addition, the length of the fitting part 192 from the position where it is joined to the drawer side wall 191 to the end in the direction of the outer wall 111 is greater than the shortest distance between the drawer side wall 191 and the support 112.

[0408] Therefore, when the support member 112 is arranged in front of the outer wall 111, when the drawer 190 is pulled out, the support member 112 is arranged on the movement path of the accessory part 192, and the accessory part 192 may interfere with the support member 112.

[0409] To solve this problem, the support member 112 of the present invention is hinged to the outer wall 111. Therefore, if the support member 112 rotates, it moves to the outside of the outer wall 111, which can avoid interference between the fitting part 192 and the drawer 190.

[0410] Therefore, in this invention, the operator can pull out the accessory part 192 after rotating the support member 112 arranged in front of the outer wall 111.

[0411] On the other hand, the robot vacuum cleaner base station 100 of the present invention can have a predetermined interval between the outer side surface of the drawer side wall 191 and the left and right ends of the outer wall 111. Furthermore, when the support member 112 is rotated outward toward the outer wall 111, a space with a predetermined interval can be formed between the drawer side wall 191 and the support member 112. In this case, the interval is preferably larger than the diameter of a human finger.

[0412] With this configuration, if an operator pulls the drawer 190 to bring the accessory section 192 closer to the support member 112, the operator rotates the support member 112 and inserts their fingers into the space between the drawer side wall 191 and the support member 112 to separate one or more hoses and / or wires connected to the accessory section 192. Then, if the operator pulls the drawer 190 further, the entire drawer 190 can be fully extended from the cover 110.

[0413] Therefore, according to the present invention, the operator can easily pull out the drawer 190 completely from the cover 110 without disassembling the kickboard of the kitchen cabinet 2.

[0414] Drawer guide rails 193 can be arranged on the drawer side wall 191 and guide the movement of the drawer side wall 191. The drawer guide rails 193 are fixedly connected to or integrally formed with the drawer side wall 191, and are combined with guide rails provided on the outer wall 111 of the cover 110, thereby guiding the movement path of the drawer side wall 191. On the other hand, while the invention describes the provision of guide rails on the drawer 190 and the cover 110, it is not necessarily limited to the form of guide rails; it may include rollers, guide grooves, or guide ribs that can replace guide rails.

[0415] On the other hand, in embodiments of the present invention, the cleaning tank 128 can be extended from the drawer 190. That is, the cleaning tank 128 can be extended together with the drawer 190, or it can be extended separately without the drawer 190 being extended. The structure of the cleaning tank 128 will be described later.

[0416] In existing robotic vacuum cleaner base stations, the cleaning component, which rubs against the mop, is detachable, while the cleaning tank containing cleaning water is fixed to the base station body. Therefore, users can separate and clean the cleaning component individually, but cannot detach the cleaning tank from the main body.

[0417] Therefore, when foreign objects in the cleaning tank dry out, it is inconvenient to clean them by lifting the entire unit or having the user lie down to wipe the cleaning tank.

[0418] To solve this problem, the cleaning tank 128 of the present invention is configured to be able to be extended from the cloth cleaning section 160. At this time, the cleaning member 122 can be extended from the cloth cleaning section 160 together with the cleaning tank 128.

[0419] Figure 25 A diagram is shown illustrating the state in which the cleaning tank and cleaning components in the base station of the sweeping robot of the present invention are led out and separated, according to an embodiment of the present invention. Figure 26 A top view of the cleaning tank in the robot vacuum cleaner base station, used to illustrate an embodiment of the present invention, is shown. Figure 27 A diagram is shown illustrating the process of introducing a cleaning tank and cleaning components into a robotic vacuum cleaner base station according to an embodiment of the present invention. Figure 28 A diagram is shown illustrating the state in which the cleaning tank and cleaning components in the base station of the sweeping robot of the present invention move in order to engage with the cleaning unit of the mop. Figure 29 A diagram is shown illustrating the state in which the cleaning tank and cleaning components are combined with the cleaning cloth part in the base station of the sweeping robot according to an embodiment of the present invention.

[0420] The following is for reference Figures 25 to 29 This invention describes the structure of the cleaning tank in the base station of the sweeping robot, as well as the process of leading out and leading in the cleaning tank.

[0421] The cleaning tank 128 in this embodiment of the invention can be led out or led in along the side wall 124.

[0422] Specifically, the drawer guide 124a can be formed by protruding from the side wall 124. For example, the drawer guide 124a can be formed by protruding from a pair of side walls 124 in a direction facing each other. In this case, the drawer guide 124a can be inclined relative to the ground. In this case, the drawer guide 124a can be configured such that the height from the ground increases as it moves from the front to the rear.

[0423] The drawer guide 124a guides the movement of the cleaning tub 128. When the cleaning tub 128 is introduced into the cover 110, the guide couplings 128a arranged on both sides of the cleaning tub 128 are inserted into the drawer guide 124a, guiding the cleaning tub 128 to move rearward. Then, with the cleaning tub 128 engaged in the cover 110, the drawer guide 124a and the guide couplings 128a engage with each other, thereby supporting the cleaning tub 128.

[0424] With this configuration, the cleaning tank 128 can be engaged in the correct position along the drawer guide 124a by the user with a simple action of pushing in the bottom component 121.

[0425] On the other hand, the joint 120 includes a cleaning groove 128, which can be led out and introduced together with the bottom member 121.

[0426] Specifically, the cleaning tank 128 can be arranged on the rear side of the bottom component body 121a. As an example, the cleaning tank 128 can be integrally formed with the bottom component body 121a. Therefore, the cleaning tank 128 can move together with the bottom component 121a.

[0427] Liquid (cleaning water) passing through the cleaning member 122 can flow into the cleaning tank 128. Specifically, liquid passing through the drain hole 122b formed in the cleaning member 122 can flow into the cleaning tank 128.

[0428] Liquid can be stored in the cleaning tank 128. Specifically, liquid that has passed through the drain hole 122b can be stored in the cleaning tank 128. For example, the cleaning tank 128 may include a bottom of the cleaning tank where liquid accumulates through the drain hole 122b and a cleaning tank wall 128d surrounding the bottom of the cleaning tank. That is, the cleaning tank 128 may be formed as a water storage tank with a downwardly recessed shape.

[0429] Liquid stored in the washing tank 128 can be drawn in through the wastewater suction nozzle 128b. The wastewater suction nozzle 128b can be connected to the wastewater suction pipe 164c provided in the cloth washing section 160. Thus, the liquid flowing in through the wastewater suction nozzle 128b can flow into the wastewater tank 164.

[0430] A guide joint 128a may be provided in the cleaning tank 128. Specifically, guide joints 128a may be provided on both sides of the cleaning tank 128 in the left-right direction.

[0431] The guide joint 128a can be formed as a plate with a specified thickness, protruding from both side walls of the cleaning tank 128, and corresponding to the shape of the drawer guide 124a. For example, the guide joint 128a can be formed with the same inclined surface as the drawer guide 124a, and when the cleaning tank 128 is engaged, it can be formed at a position where the upper surface of the drawer guide 124a and the lower surface of the guide joint 128a contact each other.

[0432] Therefore, when the cleaning tank 128 is introduced into the interior of the cover 110, the guide joint 128a is inserted into the drawer guide 124a and can guide the rearward movement of the cleaning tank 128.

[0433] A wastewater suction nozzle 128b may be provided in the cleaning tank 128. The wastewater suction nozzle 128b includes a suction nozzle connecting part 128ba that is combined with the cleaning tank 128 and a suction nozzle part 128bb that extends from the suction nozzle connecting part toward the inside of the cleaning tank 128 and bends downward.

[0434] The nozzle connector 128ba is attached to the wall of the cleaning tank 128. Specifically, the nozzle connector 128ba can be inserted into the outer side of the wall of the cleaning tank 128. For example, a hole for attaching the wastewater suction nozzle 128b can be formed in the wall of the cleaning tank 128, and the nozzle connector 128ba can be inserted into the hole. In this case, at least a portion of the nozzle connector 128ba can be arranged on the outer side of the wall of the cleaning tank 128, and the nozzle portion 118bb, integrally formed with the nozzle connector 128ba, can be arranged inside the cleaning tank 128 through the hole.

[0435] On the other hand, a wastewater suction pipe 164c and a wastewater pipe connecting member 166, which are connected to the cloth cleaning section 160 described later, can be inserted into the suction nozzle connection portion 128ba. Specifically, a port communicating with the suction nozzle portion 128bb can be formed in the suction nozzle connection portion 128ba, into which the wastewater suction pipe 164c and the wastewater pipe connecting member 166 can be inserted. For example, the port can be shaped such that its diameter increases as it approaches the outer wall of the cleaning tank 128, and the wastewater suction pipe 164c, which is connected to the wastewater pipe connecting member 166, can be inserted into the port. In this case, the wastewater pipe connecting member 166 and the suction nozzle connection portion 128ba can be sealed.

[0436] Thus, the sewage suction pipe 164c and the suction nozzle 128bb can be connected to each other.

[0437] On the other hand, a magnet 128c is attached to the nozzle connection portion 128ba. In this case, the magnet 128c can be positioned directly above the port where the wastewater suction pipe 164c is attached. The magnet 128c can be attached to the outer end of the nozzle connection portion 128ba.

[0438] Magnet 128c can generate a magnetic field. The magnetic field generated by magnet 128c can be sensed by cleaning tank combined sensor 167. This allows the connection position of nozzle 128bb and sewage suction pipe 164c to be guided.

[0439] The nozzle portion 128bb is formed by bending downwards after extending from the nozzle connecting portion 128ba towards the inside of the cleaning tank 128, so that it can be arranged separately from the bottom surface of the cleaning tank 128 at a predetermined interval. That is, one end of the nozzle portion 128bb can be connected to the nozzle connecting portion 128bb, and the other end can face the bottom surface of the cleaning tank 128.

[0440] The suction nozzle 128bb is formed in a tubular shape, and a flow path for liquid to flow can be formed inside. When the cleaning tank 128 is combined with the cloth cleaning section 160, the suction nozzle 128bb can be connected to the sewage suction pipe 164c.

[0441] Therefore, according to the present invention, the cleaning tank 128 and the cloth cleaning section 160 are detachably connected. If the cleaning tank 128 is connected to the cloth cleaning section 160, the liquid stored at the bottom of the cleaning tank 128 can be sucked in through the suction nozzle 128bb.

[0442] On the other hand, the cleaning tank 128 cleans the cloth 242 while it is connected to the cloth cleaning unit 160, and can be pulled out from the cloth cleaning unit 160 for separate cleaning.

[0443] Specifically, the cloth washing unit 160 also includes a washing tank connection 165. The washing tank connection 165 is detachably connected to the washing tank 128.

[0444] The cleaning tank joint 165 can be detachably engaged with the wall 128d of the cleaning tank 128. That is, the cleaning tank joint 165 can be arranged to face the wall 128d of the cleaning tank. When the cleaning tank 128 is engaged within the robot vacuum cleaner base station 100, the cleaning tank joint 165 can contact the wall 128d of the cleaning tank. Furthermore, if the user pulls the bottom member 121, the cleaning tank joint 165 can detach from the wall 128d of the cleaning tank and move away from it.

[0445] The cleaning tank joint 165 can be formed in a shape corresponding to the wall 128d of the cleaning tank. For example, the wall 128d of the cleaning tank can be formed as an arc shape with a specified curvature, and the cleaning tank joint 165 can be formed as an arc shape to match and engage with the wall 128d of the cleaning tank.

[0446] A wastewater suction pipe 164c may be provided at the joint 165 of the cleaning tank. The wastewater suction pipe 164c is connected to the pump flow path 164b, so that the liquid stored in the cleaning tank 128 can be guided to the wastewater tank 164.

[0447] The wastewater suction pipe 164c can be arranged behind the cleaning tank connection 165 and connected to the wastewater suction nozzle 128b. For example, the wastewater suction pipe 164c may include a pipe portion 164ca with a flow path formed internally and a support portion 164cb extending radially outward from the pipe portion 164ca and connected to the bottom surface of the cover 110 and / or the cleaning tank connection 165. In this case, the support portion 164cb of the wastewater suction pipe 164c can be connected to the suction nozzle connection portion 128ba, and the front end of the pipe portion 164ca of the wastewater suction pipe 164c can be inserted into the wastewater suction nozzle 128c and communicate with the suction nozzle portion 128bb.

[0448] With this configuration, the following effects are achieved: if the bottom member 121 is extended, the cleaning tank 128 can be extended from the cleaning tank joint 165 and cleaned separately; if the bottom member 121 is introduced, the cleaning tank 128 and the cleaning tank joint 165 are combined, thereby allowing the liquid in the cleaning tank 128 to be drawn in.

[0449] The rag washing unit 160 also includes a sewage pipe connection component 166.

[0450] The sewage pipe connecting member 166 surrounds one end of the sewage suction pipe 164c and is combined with the cleaning tank 128, thereby sealing the space between the sewage suction nozzle 128b and the sewage suction pipe 164c.

[0451] For example, the sewage pipe connection member 166 may include a sealing portion 166a formed in the shape of a pipe to surround the front end of the pipe portion of the sewage suction pipe 164c, and a fixing portion 166b extending rearward from the sealing portion and connected to the support portion of the sewage suction pipe 164c.

[0452] At this point, the sewage pipe connection component 166 can be formed of a material capable of sealing the liquid.

[0453] The sealing part 166a can be formed in a cylindrical shape to insert the sewage suction pipe 164c inside, and at least one rib can be formed protruding radially outward from the outer peripheral surface. With this configuration, the sewage suction pipe 164c and the sewage suction nozzle 128b can be sealed.

[0454] Therefore, even if the sewage suction nozzle 128b and the sewage suction pipe 164c are designed to be detachable from each other, it is possible to prevent cleaning water leakage.

[0455] The fixing part 166b can be inserted into the support part of the sewage suction pipe 164c and fix the sewage pipe connecting member 166. Thus, even if the sewage suction nozzle 128b is separated from the sewage suction pipe 164c, the sewage pipe connecting member 166 can be prevented from separating from the sewage suction nozzle 128b together.

[0456] On the other hand, the cloth cleaning unit 160 also includes a cleaning tank connection sensor 167. The cleaning tank connection sensor 167 is arranged in the sewage suction pipe 164c or the cleaning tank connection 165, and can sense the connection of the cleaning tank 128.

[0457] The cleaning tank, combined with sensor 167, can be positioned opposite magnet 128c.

[0458] For example, the cleaning tank combined with sensor 167 can be a Hall sensor. A Hall sensor can sense the magnetic field generated in magnet 128c. Therefore, the cleaning tank combined with sensor 167 can sense the presence of magnet 128c.

[0459] Therefore, if the cleaning tank 128 is engaged at the accurate position of the cleaning tank engagement portion 165, the cleaning tank engagement sensor 167 can sense that the cleaning tank 128 has been engaged at the accurate position.

[0460] At this time, the control unit (not shown) of the robot vacuum cleaner base station 100 can perform the cleaning of the mop 242 when the cleaning tank 128 is engaged in the correct position.

[0461] On the other hand, the control unit (not shown) of the robot vacuum base station 100 can restrict the movement of the mop cleaning unit 160 when the cleaning tank 128 is not engaged in the correct position. Furthermore, the control unit (not shown) of the robot vacuum base station 100 can notify the user that the cleaning tank 128 is not engaged via a display (not shown) or a speaker (not shown).

[0462] Therefore, according to the present invention, by simply pushing the cleaning tank 128 into the cleaning tank 128 after cleaning, it is possible to engage in the correct position along the drawer guide 124a, and the cleaning tank engagement sensor 167 can sense whether it is engaged in the correct position. Thus, it has the effect of preventing the leakage of sewage accumulated in the cleaning tank 128 due to inaccurate engagement of the cleaning tank 128.

[0463] 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.

[0464] 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 be further clarified by the claims.
