Description

Technical Field

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

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

[0003] Such a robotic vacuum cleaner has sensors that can identify the space to be cleaned, an agitator that can clean the floor, and a mop that can wipe the floor. It sucks up the dust on the floor in the space identified by the sensors and moves while wiping the floor with the mop.

[0004] Robotic vacuum cleaners include dry-type vacuum cleaners that remove debris by sucking up spilled objects on the floor, and wet-type vacuum cleaners that use a damp cloth to wipe the floor to effectively remove debris. Dry-type vacuum cleaners have a dustbin and use a suction motor to suck up debris from the floor. Wet-type vacuum cleaners have a water tank and are configured to supply water contained in the tank to a damp cloth, allowing the cloth to effectively remove debris from the floor. Additionally, there are vacuum cleaners that combine an agitator and a cloth.

[0005] The charging dock for a robotic vacuum cleaner is a device that allows the robot to dock after cleaning and charges its battery. The charging dock 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 are in contact with the corresponding terminals, the battery is charged by supplying power.

[0006] On the other hand, when the charging dock for a robot vacuum cleaner is placed indoors, it occupies a certain amount of indoor space. In this case, the space efficiency of the room may decrease. Additionally, when users or pets pass by, there is a possibility of collisions with the robot vacuum cleaner, resulting in injury to the user or pet, or damage to the robot vacuum cleaner.

[0007] In addition, when adding a base station with a dust collection function for robotic vacuum cleaners, the increased size may damage the interior decoration.

[0008] On the other hand, Chinese utility model patent CN218922468U discloses a base station for a vacuum cleaner located on the lower side of a washing machine. After the robot vacuum cleaner is combined with the base station, it can charge the robot vacuum cleaner, collect dust, and wash the wet cloth of the robot vacuum cleaner.

[0009] However, the aforementioned vacuum cleaner base station has an open space below the washing machine that allows the robot vacuum to enter. A detergent and water supply device for washing wet mops are installed on the vertical upper side of the space where the robot vacuum enters, and a dust bag is arranged on the side of the space where the robot vacuum enters.

[0010] With this configuration, the overall height of the vacuum cleaner base station increases, which limits its installation because it cannot utilize the space under furniture, including sinks.

[0011] In addition, since the aforementioned vacuum cleaner base station needs to be installed below the washing machine, there must be space for installing the washing machine. Considering the height of the washing machine itself and the height of the vacuum cleaner base station, there is a limitation that a space exceeding this height is required.

[0012] In addition, because the space for attaching the dust bag is close to the ground, users need to kneel or squat down in front of the base station to attach the dust bag, which is inconvenient. The space for attaching the dust bag is also narrow, which requires reaching into the base station with your hands.

[0013] Additionally, during the mop washing process of the robot vacuum cleaner, foreign objects attached to the mop may be included in the wastewater. At this time, when the wastewater is sucked into or discharged from the wastewater tank, some foreign objects that are not filtered out pass through the centrifugal pump. If used for a long time, there is a risk that foreign objects will accumulate inside the pump and cause blockage.

[0014] Furthermore, Chinese utility model patent CN218279511U discloses a point that uses a pump to create negative or positive pressure to move fluid. The aforementioned base station is configured to use an air pump and a directional valve to control the inflow and outflow of sewage.

[0015] However, using a switching valve carries the risk of leakage and pressure loss during the switching process, and having a single pump handle both inflow and outflow can lead to wear and tear. Furthermore, using a single path limits space utilization and configuration flexibility. Summary of the Invention

[0016] This invention addresses the problems of existing robotic vacuum cleaner base stations, aiming to provide a robotic vacuum cleaner base station that requires no additional installation space and can be built into the underside of a kitchen cabinet.

[0017] In addition, the purpose is to provide a robot vacuum station that can accommodate a robot vacuum in the space under a kitchen cabinet with a specified height limit.

[0018] In addition, the purpose is to provide a robot vacuum station that can automatically collect dust from the dust bin of a robot vacuum when combined with a robot vacuum.

[0019] In addition, the purpose is to provide a robot vacuum cleaner base station that can discharge sewage from the sewage tank without worrying about the pump being blocked by foreign objects when discharging sewage.

[0020] Technical means to solve the problem

[0021] To achieve the above objectives, the robot vacuum cleaner base station of the present invention may include: a cover; a cleaning tank disposed within the cover, wherein water used to wash the robot vacuum cleaner's mop is collected in the cleaning tank; a wastewater tank for storing water used to wash the mop; a wastewater suction path for moving water in the cleaning tank toward the wastewater tank; a wastewater discharge path for discharging water in the wastewater tank toward the drain pipe of the kitchen cabinet; and a wastewater discharge pump for discharging water from the wastewater tank; the wastewater discharge pump may apply air pressure to the wastewater tank.

[0022] Alternatively, a sewage suction pump may be included, which creates negative pressure in the sewage tank.

[0023] On the other hand, the wastewater tank may include a wastewater inlet for water from the cleaning tank to flow in; and a check valve for opening and closing the wastewater inlet; the check valve may only be opened when the wastewater suction pump is running.

[0024] In addition, the sewage tank may include a sewage outlet, which is connected to the sewage discharge path, and the sewage outlet may be configured at a position closer to the lower side than the sewage inlet.

[0025] In addition, the sewage inlet and the sewage outlet can be configured on the rear side of the sewage tank, and the left-right width of the rear of the sewage tank can be greater than the left-right width of the front.

[0026] On the other hand, the sewage suction pump can be configured in the sewage tank in the same direction as the side where the sewage inlet is formed.

[0027] Additionally, the wastewater discharge pump can be configured in the wastewater tank in the opposite direction to the side where the wastewater discharge outlet is formed.

[0028] On the other hand, a water level detection sensor may be included to measure the water level in the sewage tank.

[0029] In addition, the sewage discharge pump operates based on the water level detected by the water level detection sensor.

[0030] In addition, the water level detection sensor may include: a first sensor; and a second sensor located at a higher position than the first sensor above the ground.

[0031] Additionally, the first sensor can be configured at a position higher than the lowest point of the wastewater outlet, relative to the ground.

[0032] Additionally, the second sensor can be configured at a position at the same height as the lowest point of the sewage inlet, or at a position lower than the lowest point of the sewage inlet, relative to the ground.

[0033] Invention Effects

[0034] As described above, in the robot vacuum base station of the present invention, the modules for charging the robot vacuum, collecting dust, and washing the mop are arranged in a direction horizontal to the robot vacuum, thereby effectively utilizing the space under the kitchen cabinet.

[0035] In addition, the charging terminal, dust collection unit, mop washing unit, and mop drying unit are arranged around the robot vacuum cleaner, thus enabling the robot vacuum cleaner to perform multiple functions simultaneously.

[0036] In addition, since the other sides besides the front are covered by the kitchen cabinets, it provides an aesthetically pleasing effect to the user in terms of interior decoration.

[0037] In addition, by enabling the dust bags to be joined in a vertical direction, the volume occupied by the structure for loading and unloading can be reduced, thereby increasing the capacity of the dust bags.

[0038] In addition, since the intake and discharge of sewage are performed by two air pumps, it has the effect of preventing the pump from being blocked by foreign objects during the sewage discharge process. Attached Figure Description

[0102] Kitchen cabinets and vacuum cleaner system

[0103] Figure 1 A diagram is shown illustrating the state in which the vacuum cleaner 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 drain pipe connections of a vacuum cleaner system according to an embodiment of the present invention is shown.

[0104] Reference Figure 1 and Figure 2 In this embodiment of the invention, the vacuum cleaner system 1 can be installed on the underside of the kitchen cabinet 2. Specifically, the kitchen cabinet 2 can be installed in the kitchen to store bowls, plates, cups, etc., and can provide space for cooking food or washing dishes.

[0105] In addition, kitchen cabinet 2 can be equipped with a countertop (workbench) that can function as a dishwashing station, cooking station, or work station.

[0106] For example, kitchen cabinet 2 may include a sink on the countertop that provides space for washing dishes. Alternatively, kitchen cabinet 2 may include a cooking countertop for performing cooking operations. Alternatively, kitchen cabinet 2 may include a cooktop cabinet on the countertop with a gas stove, induction cooktop, infrared stove, or oven, etc.

[0107] Typically, kitchen cabinet 2 can use a standard cabinet with a front-to-back width of 600mm and a left-to-right width of 600mm.

[0108] In another embodiment of the present invention, a vacuum cleaner system 1 may 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 may represent a flow path connected to an external water supply source that supplies fluid to the structure, and the drain pipe may represent a flow path that discharges fluid from the structure into a sewer.

[0109] The lower part of such a kitchen cabinet 2 or the structure can be equipped with a storage cabinet for storing tableware and kitchen tools. That is, the kitchen cabinet 2 or the structure may include: a countertop 22 that provides space for cooking or washing dishes; a lower side panel 23 spaced apart from the ground at a predetermined height; and a storage space formed between the countertop 22 and the lower side panel 23 for storing tableware and kitchen tools. In this case, if the kitchen cabinet 2 is a sink, the countertop 22 may be equipped with a dishwashing station 22a.

[0110] Additionally, the lower side panel 23 can be supported by the base 21. The base 21 can be configured perpendicular to the kitchen floor and can support the load of the kitchen cabinet 2. At this time, depending on the height of the base 21, a space can be formed between the kitchen floor and the lower side panel 23.

[0111] In contrast, the kitchen cabinet 2 can also be fixed to the wall of the building without the need for a base 21. In this case, a space can also be formed between the kitchen floor and the lower side panel 23.

[0112] As described above, the vacuum cleaner system 1 of this embodiment is installed in the space between the kitchen floor and the lower side panel 23 (hereinafter referred to as the installation space).

[0113] For example, the installation space can be less than 200mm in height, and typically can be less than 160mm in height.

[0114] Therefore, according to the present invention, the vacuum cleaner system 1 is disposed in the lower space of the kitchen cabinet 2, thereby having the effect of minimizing the exposure of the vacuum cleaner system 1 to the outside.

[0115] In addition, compared to the case of setting up a charging dock for a robot vacuum cleaner in a specific space in the living room, bedroom or kitchen, the present invention does not occupy additional space, but instead sets up the vacuum cleaner system 1 in the unused space created by the kitchen cabinet 2, thereby maximizing space efficiency.

[0116] On the other hand, the kitchen cabinet 2 or the structure is provided with a drain pipe 25 capable of draining liquids used in cooking or water used for washing dishes. At least a portion of the drain pipe 25 can be configured in the storage space formed between the countertop 22 and the lower side panel 23. Typically, the drain pipe 25 can be connected to the drain outlet of the sink 22a formed in the sink. The drain pipe 25 includes a water trap 25a for preventing backflow of polluting gases or odors. The water trap 25a can be configured in the storage space. Liquid flowing in through the drain outlet can flow downwards due to gravity in the upstream 25b of the water trap, accumulating in the water trap 25a. If water accumulates above a predetermined level in the water trap 25a, it can flow downwards along the downstream 25c of the water trap and be discharged into the sewer.

[0117] The vacuum cleaner system 1 of this embodiment can use the drain pipe 25 as described above to wash and dry the mop 242 of the sweeping robot 200.

[0118] Additionally, although not shown in the diagram, the kitchen cabinet 2 may be equipped with a water supply pipe. Tap water (or purified water) can be supplied to the vacuum cleaner system 1 through the water supply pipe.

[0119] The following describes the specific structure of vacuum cleaner system 1.

[0120] Vacuum Cleaner System

[0121] on the other hand, Figure 3 and Figure 4 A diagram illustrating a vacuum cleaner system for demonstrating an embodiment of the present invention is shown.

[0122] The vacuum cleaner system 1 of this embodiment may include a robot vacuum base station 100 and a robot vacuum 200.

[0123] The vacuum cleaner system 1 includes a robotic vacuum cleaner base station 100. The robotic vacuum cleaner base station 100 can be integrated with a robotic vacuum cleaner 200. Specifically, the robotic vacuum cleaner 200 can enter from the front of the robotic vacuum cleaner base station 100 and can be housed inside the robotic vacuum cleaner base station 100. The robotic vacuum cleaner base station 100 can remove dust from the dustbin 220 of the robotic vacuum cleaner 200. The robotic vacuum cleaner base station 100 can wash 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.

[0124] robot vacuum

[0125] on the other hand, Figures 5 to 8 A diagram illustrating a sweeping robot system according to an embodiment of the present invention is provided.

[0126] Reference Figures 5 to 8 The structure of the robotic vacuum cleaner 200 is described below.

[0127] The 200 robotic vacuum cleaner can automatically clean the area that needs cleaning by sucking up dust and other foreign objects from the ground while moving automatically in the area that needs cleaning.

[0128] The robotic vacuum cleaner 200 of this embodiment is configured to clean the floor while moving on the floor after being placed on it. Therefore, the vertical direction will be defined and explained below based on the state of the robotic vacuum cleaner 200 placed on the floor.

[0129] Furthermore, taking a pair of wheels 260 as a reference, the side where the auxiliary wheel 270 (described later) is located is defined as the front, and the side where the rotating cleaning unit 240 (described later) is located is defined as the rear, and will be explained accordingly.

[0130] The “lowest part” of each configuration described in the embodiments of the present invention may be the part located at the lowest point in each configuration when the sweeping robot 200 of the embodiments of the present invention is placed on the ground and used, or it may be the part closest to the ground.

[0131] 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.

[0132] The main body 210 can form the overall appearance of the robotic vacuum cleaner 200. The main body 210 can be combined with various components that constitute the robotic vacuum cleaner 200, and some of the components that constitute the robotic vacuum cleaner 200 can be housed inside the main body 210.

[0133] Specifically, the space inside the main body 210 can house the components of the robotic vacuum cleaner 200. For example, the space inside the main body 210 can accommodate a battery and at least one motor.

[0134] In this embodiment of the invention, the main body 210 can be configured such that its width (or diameter) in the horizontal direction is greater than its height in the vertical direction. Such a main body 210 helps to make the robot vacuum cleaner 200 have a stable structure and can provide a structure that facilitates the robot vacuum cleaner 200 in avoiding obstacles when moving (driving).

[0135] When viewed from above or below, the main body 210 can be formed into various shapes such as a circle, an oval, or a quadrilateral.

[0136] The main body 210 can be divided into a lower main body and an upper main body. By combining the lower main body and the upper main body, a space can be formed inside.

[0137] The lower body can be combined with the upper body to form an internal space that can accommodate a battery, at least one sensor, and at least one motor.

[0138] The lower body may have an intake section 211 for air to flow in and a hole for accommodating a pair of wheels 260.

[0139] The suction section 211 can be a passage for dust from the ground to flow in. In addition, 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.

[0140] On the other hand, the lower main body can also be provided with an exhaust flow path. 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. In this case, the exhaust port can be equipped with a filter.

[0141] With the above configuration, the air flowing in through the suction section 211 can flow into the dust bin 220 through the suction flow path, and then be discharged to the exhaust port through the exhaust flow path.

[0142] The agitator 250, described later, can be rotatably housed in the suction section 211. With the above configuration, dust around the suction section 211 can be drawn into the suction section 211 by the rotation of the agitator 250, thereby improving the efficiency of dust suction.

[0143] The upper body can form the upper appearance of the robotic vacuum cleaner 200. Although not shown in the diagram, the upper body may be equipped with a display screen.

[0144] The robotic vacuum cleaner 200 of the present invention may include a bumper strip. The bumper strip is attached along the edge of the body 210 and is configured to move relative to the body 210.

[0145] The bumper strip can be attached to a portion of the edge of the main body 210, or to the entire edge of the main body 210. At least one elastic member (not shown) can be provided between the bumper strip and the main body 210. With this configuration, if the bumper strip comes into contact with an obstacle or the like and moves relative to the center of the main body 210, the bumper strip can return to its original position under the restoring force of the elastic member (not shown). This allows the bumper strip to absorb or disperse the impact applied to it, preventing and reducing the transmission of impact to the main body 210.

[0146] The dust bin 220 can be configured to draw in external dust and air and store the dust.

[0147] 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.

[0148] 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 can also be disposed detachably according to the embodiment.

[0149] On the other hand, the dust bin 220 of the present invention can be formed with a dust discharge path. 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 using the robotic vacuum cleaner base station 100, the dust inside the dust bin 220 can be removed.

[0150] On the other hand, the dust bin 220 of this embodiment of the invention may have a dust outlet 221 communicating with the dust discharge flow path. As one example, the dust outlet 221 may be formed on the rear side of the outer side (or outer peripheral surface) of the main body 210. As another example, the dust outlet 221 may be formed on the outer side of the dust bin 220.

[0151] 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 aforementioned dust outlet 221. Specifically, the dust bin door 222 may be integrated with the main body 210 and may be positioned to block the dust outlet 221. As an example, the dust bin door 222 may be formed of rubber or resin material and be rotatable, with one side fixedly integrated with the main body 210.

[0152] With the above configuration, if the dust collection motor 145 of the robot vacuum base station 100 described later is running, the dust bin door 222 will be elastically deformed under the driving force of the dust collection motor 145, the dust discharge port 221 will open, and the dust in the dust bin 220 can be collected into the dust collection section 140 of the robot vacuum base station 100.

[0153] The bucket 230 is configured as a container with an internal space to store liquids such as water inside. The bucket 230 is disposed inside the main body 210 and can be fixedly attached to the main body 210 or detachably attached to the main body 210.

[0154] The water tank 230 includes a supply section 231 and a nozzle (not shown). The supply section 231 can be configured to supply liquids such as water from the outside. For example, the supply section 231 can have an inlet formed on the other side behind the outer side (or outer peripheral surface) of the main body 210, which can be connected to the storage space inside the water tank 230 via a water supply hose.

[0155] At this time, the supply unit 231 can be configured on the opposite side of the sweeping robot 200 in the left-right direction in relation to the dust discharge port 221. For example, if the dust discharge port 221 is configured on the rear left side of the main body 210, the supply unit 231 can be configured on the rear right side of the main body 210.

[0156] With the above 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.

[0157] On the other hand, the nozzle (not shown) can be formed in the shape of a tube or pipe and can be connected to the bucket 230 so that the liquid inside the bucket 230 flows through the inside of the nozzle. One side of the nozzle (not shown) is connected to the bucket 230, and the other end is configured to be located above or on the rotating plates 241 respectively, thereby enabling the liquid inside the bucket 230 to be supplied to the pair of cloths 242 respectively.

[0158] That is, the nozzle (not shown) can be configured as a tube branching into two, in which case either end of the branch can be located on the upper side of the left rag, and the other end of the branch can be located on the upper side of the right rag.

[0159] On the other hand, although not shown, the water tank 230 may be equipped with a pump to allow water inside the water tank 230 to flow to the nozzle (not shown). Therefore, if the pump in the water tank 230 is running, the liquid stored in the water tank 230 can be discharged through the nozzle (not shown) to the rotating cleaning unit 240.

[0160] The rotating cleaning unit 240 includes a rotating plate 241 and a cleaning cloth 242.

[0161] The rotating plate 241 can be configured as a pair including a left rotating plate and a right rotating plate, and the rag 242 can be configured as a pair including a left rag and a right rag.

[0162] The rotating plate 241 can be rotatably disposed on the bottom surface of the main body 210, and the rag 242 can be attached to the underside of the rotating plate 241.

[0163] The rotating plate 241 is configured with a specified area and is shaped as a flat plate or a flat frame. This rotating plate 241 is typically placed horizontally, thus its horizontal width (or diameter) is much greater than its vertical height. The rotating plate 241, attached to the main body 210, can be parallel to the bottom surface or inclined to it. The rotating plate 241 can be configured as a circular plate, its bottom surface can be approximately circular, and the rotating plate 241 can be configured as a whole with rotational symmetry.

[0164] A pair of rotating plates 241 can be arranged to be symmetrical to each other.

[0165] The rag 242 can be attached to the underside of the rotating plate 241 so as to be opposite the ground.

[0166] The bottom surface of the rag 242 facing the ground has a defined area, and the rag 242 is flat. The width (or diameter) of the rag 242 in the horizontal direction is much greater than its height in the vertical direction. As the rag 242 is attached to one side of the main body 210, the bottom surface of the rag 242 can be parallel to the ground or can be inclined to the ground.

[0167] The bottom surface of the rag 242 can be roughly circular, and the rag 242 can be configured as a whole in a rotationally symmetrical shape. In addition, the rag 242 can be attached to the bottom surface of the rotating plate 241, and can be combined with the rotating plate 241 to rotate together with the rotating plate 241.

[0168] On the other hand, although not shown in the figure, the rotary cleaning unit 240 may be provided with a drive unit that applies rotational force to the rotary plate 241. For example, the drive unit may have a motor and at least one gear. Therefore, when the drive unit is running, the rotary plate 241 and the mop 242 rotate while wiping the floor to perform cleaning.

[0169] The agitator 250 may be rotatably equipped with a plurality of brushes to direct external dust and air toward the dust bin 220. At this time, the agitator 250 may be equipped with at least one gear.

[0170] On the other hand, the agitator 250 of this embodiment can not only be provided with an additional agitator motor (not shown) to receive rotational power, but according to the embodiment, it can also receive rotational power from a driving motor or from the drive unit of the rotating cleaning unit 240.

[0171] 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.

[0172] Wheel 260 can be installed on the main body 210 and can roll on the ground.

[0173] Wheel 260 can be composed of a first driving wheel and a second driving wheel. In this case, the first driving wheel can be constructed in the same way as the second driving wheel, or symmetrically. As an example, if the first driving wheel is located on the left side of the robot vacuum cleaner 200, then the second driving wheel can be located on the right side of the robot vacuum cleaner 200. In this case, the first driving wheel and the second driving wheel can be symmetrical to each other.

[0174] 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 can provide power to the wheel 260. The travel motor may include a first travel motor and a second travel motor.

[0175] The travel motor can be an electric motor. A plurality of gears are configured to mesh and rotate, connecting the travel motor and the wheel 260, transmitting the rotational power of the travel motor to the wheel 260. Therefore, when the rotating shaft of the travel motor rotates, the wheel 260 can rotate.

[0176] With the above configuration, if the driving motor is running, the wheel 260 rotates, and the main body 210 can travel on the ground at a specified speed.

[0177] The auxiliary wheel 270 can be disposed on the underside of the main body 210 and can roll on the ground (the surface to be cleaned). The auxiliary wheel 270, together with a pair of wheels 260, can support the main body 210 on the ground. With the above configuration, the auxiliary wheel 270 can guide the movement of the robot vacuum cleaner 200 while minimizing friction between the robot vacuum cleaner 200 and the ground.

[0178] The suction motor (not shown) generates suction that draws in external dust and air via 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.

[0179] Although not shown, the battery is integrated into the main body 210 to power other components constituting the robotic vacuum cleaner 200. The battery can power at least one or more motors provided in the robotic vacuum cleaner 200. For example, the battery can power motors provided in the rotary cleaning unit 240, agitator 250, wheels 260, and suction motor (not shown).

[0180] In addition, the battery can power the sensor unit (not shown) and the control unit (not shown).

[0181] The battery can be charged using an external power source, and for this purpose, a charging terminal 280 can be provided on one side of the main body 210. For example, the charging terminal 280 can be located on the rear side of the outer side of the main body 210. If the robot vacuum cleaner 200 is combined with the robot vacuum cleaner base station 100, the charging terminal 280 can contact and be powered by the power supply terminal 123b of the robot vacuum cleaner base station 100.

[0182] Robot vacuum cleaner base station

[0183] Reference Figures 3 to 15 The sweeping robot base station 100 of the present invention is described below.

[0184] The robot vacuum cleaner base station 100 can accommodate a robot vacuum cleaner 200. The robot vacuum cleaner 200 can be integrated into the mounting section 120 of the robot vacuum cleaner base station 100.

[0185] The robot vacuum cleaner base station 100 may include a cover 110.

[0186] 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 or more outer wall surfaces.

[0187] The interior of the cover 110 can be formed with a space that can accommodate the placement section 120, the door section 130, the dust collection section 140, the cloth washing section 160, and the cloth drying section 170.

[0188] The cover 110 can be installed on the underside of the kitchen cabinet 2. Specifically, the cover 110 can be installed in the mounting space formed between the lower side panel 23 of the kitchen cabinet 2 and the kitchen floor.

[0189] The enclosure 110 includes a pair of outer walls 111 that are opposite each other. The outer walls 111 may represent surfaces formed along the direction of gravity.

[0190] As an example, a pair of outer walls 111 can be spaced apart by a predetermined interval and positioned on the lower side of the kitchen cabinet 2. In this case, the cover 110 can also include a bottom surface 112 opposite to the kitchen floor, through which the pair of outer walls 111 can be connected. On the other hand, the cover 110 can also include an upper cover 113 opposite to the lower side panel 23 of the kitchen cabinet 2, which can be detachably attached to the upper end of the pair of outer walls 111. Therefore, even if foreign objects fall from the kitchen cabinet 2 to the lower side, it is possible to prevent contamination of the components of the robot vacuum cleaner 200 and the robot vacuum cleaner base station 100. Additionally, the cover 110 can also include a rear surface 115 facing the wall of the building. With the above configuration, the components of the robot vacuum cleaner base station 100 can be accommodated inside the cover 110 (between the pair of outer walls).

[0191] Additionally, the enclosure 110 can accommodate the robotic vacuum cleaner 200. The enclosure 110 can be configured such that the gap between its outer walls 111 is greater than the maximum horizontal width of the robotic vacuum cleaner 200. With the above configuration, the robotic vacuum cleaner 200 can enter and exit the enclosure 110.

[0192] In this embodiment, the robotic vacuum cleaner 200 can enter and exit from the front of the robotic vacuum cleaner base station 100. Here, "front" can refer to the direction in which the door 131 is set with reference to the interior of the robotic vacuum cleaner base station 100.

[0193] 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 disposed behind the robotic vacuum cleaner base station 100.

[0194] Furthermore, based on the view looking forward from inside the robot vacuum cleaner base station 100, the left side can be referred to as the left side and the right side can be referred to as the right side.

[0195] That is, the outer wall 111 of the robot vacuum cleaner base station 100 can be configured on the left side and the right side respectively.

[0196] 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. Furthermore, although the left and right sides of the cover 110 are covered by the outer wall, they are located at the lower part of the kitchen cabinet 2. Since the lower part of the kitchen cabinet 2, excluding the robot vacuum base station 100, is edged by the baseboard 26, only the front of the cover 110 can be exposed to the outside.

[0197] This minimizes the exposure of the robot vacuum base station 100 and the robot vacuum 200 to the outside.

[0198] With the above configuration, the robot vacuum cleaner base station 100 of the present invention has the effect of providing aesthetic appeal to users in terms of decoration.

[0199] On the other hand, the cover 110 may have a space for a water supply hose connected to a water supply pipe to pass through, a space for a drainage hose to pass through for wastewater generated after washing the cloth 242, and a space for a hose to discharge water generated during the drying of the cloth 242. For example, a space for the aforementioned hose to pass through may be formed on the outer wall 111 of the cover 110.

[0200] layout

[0201] The sweeping robot base station 100 of this embodiment is characterized in that the sweeping robot base station 100 is installed in the lower space of the kitchen cabinet 2.

[0202] Therefore, the robot vacuum cleaner base station 100 of this embodiment is characterized in that the robot vacuum cleaner base station 100 is arranged horizontally in a space matching the space between the lower side panel 23 of the kitchen cabinet 2 and the kitchen floor.

[0203] Specifically, in the robot vacuum cleaner base station 100 of this embodiment, the dust collection unit 140 and / or the mop washing unit 160 can be configured on the side of the entrance 127.

[0204] At this time, with the dust collection unit 140 and the cloth washing unit 160 provided, the placement unit 120 can be arranged between the dust collection unit 140 and the cloth washing unit 160.

[0205] For example, an entrance / exit 127 and a door 131 may be configured at the front of the robotic vacuum cleaner base station 100. Additionally, a mounting section 120 for the robotic vacuum cleaner 200 to be attached may be configured rearward from the entrance / exit 127. In this case, the dust collection section 140 may extend rearward from the front of the robotic vacuum cleaner base station 100 by a predetermined length. Furthermore, the mop washing section 160 may also extend rearward from the front of the robotic vacuum cleaner base station 100 by a predetermined length.

[0206] 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 washing unit 160 can be arranged on the left and right sides of the entrance 127.

[0207] At this time, the dust bag drawer 144 of the dust collection unit 140 can be configured to extend outward toward the front of the cover 110. In addition, the detergent bucket 163 of the cloth washing unit 160 can be configured to extend outward toward the front of the cover.

[0208] On the other hand, the rear ends of the dust collection hood 141 and the detergent tank 163 can be arranged at a predetermined interval from the rear end of the hood 110. Furthermore, a dust collection motor 145 can be arranged between the rear end of the dust collection hood 141 and the rear end of the hood 110. With the above configuration, the overall space occupied by the mounting section 120, the dust collection hood 141, and the dust collection motor 145 within a limited space is minimized.

[0209] Furthermore, at least a portion of a flow path for the flow of washing water for washing the cloth 242 can be configured between the rear end of the cover 110 and the rear end of the detergent tank 163. With this configuration, the path of the washing water flowing from the water supply pipe can be minimized. Additionally, it has the effect of minimizing the overall space occupied by the housing 120, the detergent tank 163, and the flow path for the washing water in a limited space.

[0210] On the other hand, in the robot vacuum cleaner base station 100, the cloth drying unit 170 can be configured closer to the rear than the mounting unit 120. In this case, the cloth drying unit 170 can be configured between the rear end of the mounting unit 120 and the rear end of the cover 110.

[0211] Therefore, in the robot vacuum cleaner base station 100 of this embodiment, a dust collection unit 140 and a cloth washing unit 160 can be arranged on the left and right sides based on the placement unit 120, and a cloth drying unit 170 can be arranged on the rear side.

[0212] 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 may be arranged within a predetermined distance range from the outer contour of the placement unit 120.

[0213] This shortens the distance between the dust bin 220 and the dust collection unit 140 of the robotic vacuum cleaner 200, thereby minimizing flow path loss. Furthermore, by maximizing the reduction of the distance between the mop 242 and the mop washing unit 160, and between the mop 242 and the mop drying unit 170, the area where washing water and wastewater remain is effectively limited.

[0214] Furthermore, with this configuration, the robotic vacuum cleaner base station 100 of the present invention can be configured with all its components within a limited height.

[0215] As a result, in the robot vacuum base station 100 of this embodiment, the three sides of the surrounding placement part 120, excluding the front side where the robot vacuum 200 enters, can be equipped with a dust collection part 140, a mop washing part 160, and a mop drying part 170. With this configuration, even when the vertical height is limited, the robot vacuum 200 can be charged using minimal horizontal space, and the dust from the robot vacuum 200 can be collected, the mop 242 can be washed, and the mop 242 can be dried.

[0216] Resettlement Department

[0217] like Figures 12 to 15 As shown, the robot vacuum cleaner base station 100 may include a mounting unit 120.

[0218] The robotic vacuum cleaner 200 and the robotic vacuum cleaner base station 100 can be physically connected, electrically connected, and / or connected via the mounting unit 120.

[0219] The mounting section 120 can be installed inside the cover 110.

[0220] An entrance 127 for the robotic vacuum cleaner 200 to enter can be formed in front of the installation unit 120. The entrance 127 can represent the space formed in front of the robotic vacuum cleaner base station 100.

[0221] The entrance / exit 127 can be sized to allow the robotic vacuum cleaner 200 to pass through. That is, the height of the entrance / exit 127 can be greater than the height of the robotic vacuum cleaner 200. In this case, the entrance / exit 127 can represent a space formed vertically upward from the front end of the base 121 (described later). Alternatively, the entrance / exit 127 can represent a hole formed in the door frame 132 (described later) for the robotic vacuum cleaner 200 to pass through.

[0222] At least one of a dust collection section 140 and a cloth washing section 160 may be disposed on the left and right sides of the entrance / exit 127. Therefore, the left and right ends of the entrance / exit 127 may form boundaries with the dust collection section 140 and the cloth washing section 160.

[0223] At this time, entrance / exit 127 can be opened and closed using door 131.

[0224] The placement part 120 may include a receiving space S, a base 121, a connecting wall 123, and an inner wall 124.

[0225] The receiving space S of the placement section 120 can accommodate the robotic vacuum cleaner 200. As one example, the receiving space S can represent the space surrounded by the base 121, the connecting wall 123, and the inner wall 124. As another example, the receiving space S can represent the space surrounded by the base 121, the washing plate 122, the connecting wall 123, and the inner wall 124. As yet another example, the receiving space S can represent 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.

[0226] The base 121 is configured to support the robot vacuum 200 when it is integrated with the robot vacuum base station 100. The upper side of the base 121 can contact the wheels 260 of the robot vacuum 200. In addition, the upper side of the base 121 can contact the auxiliary wheels 270 of the robot vacuum 200.

[0227] The base 121 may include a base body 121a, an inclined portion 121b, a wheel engagement portion 121c, an agitator receiving portion 121d, and a cleaning tank 128.

[0228] The base body 121a can form the overall appearance of the base 121. The base body 121a can be equipped with an inclined part 121b, a wheel engagement part 121c, an agitator receiving part 121d, and a cleaning tank 128.

[0229] The base body 121a can be configured such that its length and width in the horizontal direction are greater than its height in the vertical direction. This structure enables the robotic vacuum cleaner base station 100 to be stably supported on the ground.

[0230] The base body 121a may have a return flow path inside. Therefore, the air discharged from the dust collection motor 145 can flow through the return flow path 125a formed inside the base body 121a and then be discharged to the air return port 125b.

[0231] The tilting part 121b can be configured in the base body 121a at the entrance for the robot vacuum cleaner 200 to climb.

[0232] The tilting portion 121b may have a forward tilt that rises in the direction in which the robotic vacuum cleaner 200 enters. More specifically, the front end of the tilting portion 121b may be connected to the ground without any height difference, but has a slope that slopes upwards towards the rear. That is, the tilting portion 121b may be configured to gradually rise from the ground when the robotic vacuum cleaner 200 enters. Therefore, the robotic vacuum cleaner 200 can easily climb onto the robotic vacuum cleaner base station 100 from the ground.

[0233] A wheel guide 121ba may be provided in the inclined section 121b.

[0234] 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 correspondingly to the surface of the wheel 260 to enable the robotic vacuum cleaner 200 to move stably. Furthermore, the width of the groove in the wheel guide portion 121ba at the entry point where the robotic vacuum cleaner 200 climbs is greater than the width of the wheel 260, and the width of the groove can be narrowed towards the front of the robotic vacuum cleaner 200's climbing path compared to the entry point. Therefore, the wheels 260 of the robotic vacuum cleaner 200 can easily enter the robotic vacuum cleaner base station 100, and the gradually narrowing groove restricts lateral movement and guides the wheels 260 to the correct position.

[0235] An auxiliary wheel guide 121bb may be provided in the inclined section 121b.

[0236] 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 protruding shape so that when the wheel 260 of the robotic vacuum cleaner 200 is placed on the wheel guide portion 121ba, it contacts the auxiliary wheel 270. Therefore, when the robotic vacuum cleaner 200 moves on the tilting portion 121b, not only the wheel 260, but also the auxiliary wheel 270 can be stably supported and used for movement.

[0237] The wheel 260 of the robotic vacuum cleaner 200, which moves upward with the wheel guide 121ba, can be mounted in the wheel engagement portion 121c. If the wheel 260 of the robotic vacuum cleaner 200 is mounted in the wheel engagement portion 121c, a physical connection between the robotic vacuum cleaner 200 and the robotic vacuum cleaner base station 100 can be achieved. The surface of the wheel engagement portion 121c can be formed correspondingly to the surface of the wheel 260, so that the robotic vacuum cleaner 200 can stop stably. The wheel engagement portion 121c can extend from the upper end of the wheel guide 121ba. The wheel engagement portion 121c can connect to the wheel guide 121ba without forming a step. Therefore, the robotic vacuum cleaner 200 can easily move to the wheel engagement portion 121c via the tilting portion 121b.

[0238] The wheel engagement portion 121c can be configured at the stop position of the left and right side wheels 260 of the robotic vacuum cleaner 200 so that the robotic vacuum cleaner 200 stops in the correct position. Here, the stop position of the wheels 260 refers to the stop position specified for connecting the robotic vacuum cleaner 200 to the power supply terminal 123b and / or the stop position specified for connecting the dustbin 220 of the robotic vacuum cleaner 200 to the dust passage hole 123a.

[0239] The shape of the wheel engagement portion 121c can be formed into an arch 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 with the wheel guide portion 121ba, and can stop when the wheel is inserted into the wheel engagement portion 121c, and the wheel 260 can be stably placed in the arch-shaped wheel engagement portion 121c.

[0240] The agitator receiving section 121d can accommodate at least a portion of the agitator 250 of the robot vacuum cleaner 200.

[0241] An agitator receiving portion 121d can be formed between the wheel engagement portions 121c. The agitator receiving portion 121d can be shaped to correspond to the agitator 250 of the robotic vacuum cleaner 200. The agitator receiving portion 121d can be shaped as a cuboid with an open upper portion. The bottom surface of the agitator receiving portion 121d can be sealed by the bottom surface of the base body 121a or the bottom surface of the cover 110. Therefore, the agitator 250 of the robotic vacuum cleaner 200, which moves upward along the inclined portion 121b, can be placed in 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 less than the depth of the wheel engagement portion 121c.

[0242] The agitator receiving portion 121d can be recessed into the base body 121a. In this way, with the wheels 260 of the sweeping robot 200 placed in the wheel engagement portion 121c, the agitator receiving portion 121d can provide space to accommodate the lower end of the agitator 250.

[0243] An air return port 125b may be formed in the agitator housing 121d. The air return port 125b may be formed on the side of the agitator housing 121d. The air return port 125b can connect the recess 121da to the dust collection motor 145 through a return flow path. The recess 121da and the return flow path can be connected through the air return port 125b. Therefore, the air discharged from the dust collection motor 145 can pass through the air return port 125b and be discharged into the recess 121da of the agitator housing 121d.

[0244] The agitator housing 121d can direct the air expelled through the air return port 125b to the suction unit 211 of the robot vacuum cleaner 200.

[0245] On the other hand, the base 121 can be configured to be extended from the cover 110 and the drawer 190. In this case, the base 121 can be extended through the inlet 127 along the space between the inner walls 124.

[0246] To facilitate this operation, the base 121 may be provided with a base handle 121e. The base handle 121e may be formed between the agitator housing 121d and the auxiliary wheel guide 121bb. Alternatively, the base handle 121e may be formed between a pair of wheel guides 121ba.

[0247] The base handle 121e can be formed as a recess in the base body 121a, or it can be formed as a recess from the rear to the lower front. For example, the base handle 121e can be formed as an elliptical groove, with a cover in the front and an open shape in the rear.

[0248] With the above configuration, the user can easily pull out the base 121 by holding the handle 121e and pulling it.

[0249] The connecting wall 123 is configured to accommodate the dust passage 123a, power supply terminal 123b, and water supply nozzle 123c of the robot vacuum base station 100. The connecting wall 123 spatially separates the accommodating space S and the components of the robot vacuum base station 100. The connecting wall 123 extends vertically from the rear side of the base 121. The connecting wall 123 can be formed to correspond to the shape of the robot vacuum 200. For example, if the main body 210 of the robot vacuum 200 is cylindrical, the connecting wall 123 can be formed as an arc shape with a predetermined radius. With this configuration, the outer contour of the robot vacuum 200 can be surrounded, increasing the area that can be opposite the outer surface of the robot vacuum 200. Furthermore, it can stably support the robot vacuum 200.

[0250] A dust passage hole 123a can be formed in the mounting section 120 to allow air from outside the cover 110 to flow into the interior. Specifically, a dust passage hole 123a can be formed in the connecting wall 123 to allow air from outside the cover 110 to flow into the interior. In this case, the dust passage hole 123a can be located behind the dust collection section cover 141, which will be described later.

[0251] The dust can communicate with the dust bin 220 of the robot vacuum 200 through the hole 123a. The dust can also communicate with the dust outlet 221 of the dust bin 220 of the robot vacuum 200. The dust can be formed in a hole shape corresponding to the shape of the dust bin 220 so that the dust in the dust bin 220 flows into the dust collection section 140.

[0252] Dust can be connected to the dust collection flow path 147, 148 through the dust passage 123a. Air drawn into the dust passage 123a can flow in the dust collection flow path 147, 148 and then be discharged through the air return section 125.

[0253] The robotic vacuum cleaner base station 100 may include a power supply module for supplying power to the robotic vacuum cleaner 200. The power supply module may include a power supply module housing and power supply terminals 123b. The power supply module housing may house circuit boards and components for power supply. Additionally, the power supply terminals 123b may be positioned forward from the power supply module housing to be exposed on the connecting wall 123.

[0254] The power supply terminal 123b can supply power to the robotic vacuum cleaner 200 attached to the mounting section 120. The power supply terminal 123b can contact and be electrically connected to the charging terminal of the robotic vacuum cleaner 200. The power supply terminal 123b can be disposed in the mounting section 120. Specifically, the power supply terminal 123b can be disposed in the mounting wall 123. The power supply terminal 123b can be electrically connected to the robotic vacuum cleaner 200 attached to the mounting wall 123. The power supply terminal 123b can supply power to the battery of the robotic vacuum cleaner 200 attached to the mounting wall 123.

[0255] The robot vacuum cleaner base station 100 may also include a water supply nozzle 123c.

[0256] The water supply nozzle 123c can be connected to the supply section 231 of the water tank 230 of the robot vacuum cleaner 200. Specifically, the water supply nozzle 123c can be connected to the inlet of the water tank 230. The water supply nozzle 123c can supply water supplied from the water supply pipe of the kitchen cabinet 2 to the storage space inside the water tank 230 of the robot vacuum cleaner 200.

[0257] The inner wall 124 is a component that spatially divides the accommodating space S of the placement section 120 and the robot vacuum base station 100. A pair of inner walls 124 can be arranged on the left and right sides of the base 121. The inner walls 124 can be connected to both ends of the connecting wall 123. The inner walls 124 can extend from the left and right sides of the base 121 in a direction intersecting with the base 121. Specifically, the inner walls 124 can extend vertically from the left and right sides of the base 121.

[0258] On the other hand, various components such as dust collection paths 147 and 148, dust collection section 140, dust collection motor 145, detergent tank 163, and wastewater tank 166 can be arranged on the outer side of the inner wall 124. Specifically, the space between the inner wall 124 and the outer wall 111 of the cover 110 can be used to arrange the dust collection section 140, detergent tank 163, and wastewater tank 166.

[0259] The dust collection section 140 and the detergent container 163 can slide apart from the space between the inner wall 124 and the outer wall 111 of the cover 110. The lateral width of the dust collection section 140 and the detergent container 163 can be less than the distance between the inner wall 124 and the outer wall 111 of the cover 110.

[0260] The washing plate 122 serves as a component for washing the cleaning cloth of the robotic vacuum cleaner 200, and can be placed in the washing tank 128 of the base 121. Furthermore, the washing plate 122 can contact the cleaning cloth 242 while the robotic vacuum cleaner 200 is in place.

[0261] The washing board 122 can be a board that is sloping downwards towards the center.

[0262] Specifically, the washing plate 122 includes a flow guiding surface 122c formed in a curved shape. Furthermore, the flow guiding surface 122c may have at least one or more through holes 122b for fluid passage. Additionally, the flow guiding surface 122c may have protruding washing protrusions 122a.

[0263] At this time, a pair of washing protrusions 122a can be symmetrically formed on the flow guide surface 122c. Specifically, the pair of washing protrusions 122a can be disposed on the vertical lower side of the pair of mop pads 242 of the robot vacuum cleaner 200, disposed opposite to the pair of mop pads 242, and disposed to be able to contact at least a portion of the pair of mop pads 242.

[0264] Additionally, a plurality of through holes 122b may be formed on the flow guiding surface 122c and between a pair of washing protrusions 122a. For example, a plurality of through holes 122b may be formed on the flow guiding surface 122c at the lowest position from the ground (kitchen floor) and between a pair of washing protrusions 122a. In this way, fluid expelled between the pair of washing protrusions 122a can be guided to flow through the through holes 122b.

[0265] On the other hand, the flow guide surface 122c can be positioned further back from the location where the through hole 122b is formed, and its height above the kitchen floor can be increased. That is, the flow guide surface 122c can be positioned closer to the external gas outlet 171c, which will be described later, and its height above the kitchen floor can be increased.

[0266] With this configuration, washing water and / or air can flow along the flow guide surface 122c and escape through the through hole 122b into the space formed between the washing plate 122 and the washing tank 128.

[0267] If washing water is supplied to the washing plate 122 and the cloth 242 rotates, the cloth 242 can be rubbed against the stationary washing protrusion 122a and washed.

[0268] On the other hand, at least a portion of the washing plate 122 may be disposed on the upper side of the flow path forming portion 128c described later. That is, the washing plate 122 may also include a return flow path covering portion 122d, which protrudes upward from the flow guide surface 122c and is attached to the upper side of the flow path forming portion 128c.

[0269] In this embodiment, the washing plate 122 can be formed in a shape corresponding to the shape of the flow path forming portion 128c. For example, the front left side portion of the washing plate 122 can be formed by protruding upward from the flow guide surface 122c to cover the lower flow path forming portion 128c.

[0270] This configuration allows the washing plate 122 to be accurately combined with the washing tank 128 while providing sufficient space to form a return flow path 125a.

[0271] The cleaning tank 128 is configured to house the washing plate 122. The cleaning tank 128 can be disposed on the rear side of the base body 121a. The cleaning tank 128 is disposed on the underside of the washing plate 122 and is detachably coupled to the washing plate 122. The cleaning tank 128 can be formed correspondingly to the washing plate 122 so that the washing plate 122 can be inserted. Liquid that has passed through the washing plate 122 can flow into the cleaning tank 128. The cleaning tank 128 can be disposed inside the cover 110, and water from the cleaning cloth 242 of the robotic vacuum cleaner 200 can be collected in the cleaning tank 128.

[0272] The cleaning tank 128 may include a cleaning tank base surface 128a for fluid flow through the washing plate 122 and a cleaning tank wall 128b extending vertically from the outer contour of the cleaning tank base surface 128a. The cleaning tank base surface 128a can be positioned closer to the rear of the robot vacuum cleaner base station 100, with a lower height from the ground (kitchen floor). This allows the fluid passing through the washing plate 122 to be collected at the rear of the cleaning tank 128 and then discharged externally through the wastewater suction nozzle 166a (described later).

[0273] At this time, in order to connect with the sewage suction nozzle 166a, a sewage pipe connection port 128d can be formed on the cleaning tank wall 128b.

[0274] On the other hand, the cleaning tank 128 may have a flow path forming portion 128c. The flow path forming portion 128c may be formed by protruding upward from the base surface 128a of the cleaning tank to form a return flow path 125a on the lower side. Specifically, at least a portion of the return flow path 125a may be formed between the lower side of the base 121 and the flow path forming portion 128c.

[0275] On the other hand, the washing tank 128 of the present invention is configured to be able to be extended from the cloth washing section 160. That is, the washing tank 128 can be extended from the cover 110 together with the base 121. At the same time, the washing plate 122 can also be extended from the cloth washing section 160.

[0276] Door

[0277] Door 130 may be configured to cover the entire front end of cover 110. Door 131 may cover dust bag drawer 144 and detergent container 163 so that they are not exposed to the outside.

[0278] Door 131 forms the front appearance of the robotic vacuum cleaner base station 100 when the entrance / exit 127 is closed. For example, door 131 can be shaped like a rectangular flat panel. The length of door 131 in the left-right direction can be greater than or equal to the length of the cover 110 in the left-right direction. With this configuration, the dust bag drawer 144 and detergent container 163 can be protected from external influences, thereby achieving the effect of keeping the appearance of the robotic vacuum cleaner base station 100 clean.

[0279] A door frame 132 may be provided at the front of the cover 110. A door 131 is connected to the door frame 132 in an openable and closable manner. In addition, the door frame 132 may form an entrance 127 for the robot vacuum cleaner 200 to enter and exit, a dust bag outlet 132a connected to the dust bag drawer 144, and a detergent bucket insertion port 132b connected to the detergent bucket 163.

[0280] The door frame 132 can form the front appearance of the robot vacuum cleaner base station 100 when the door 131 is open.

[0281] The dust bag drawer 144 and detergent container 163, which are integrated into the door frame 132, can be configured such that at least one side of the dust bag drawer 144 and at least one side of the detergent container 163 are exposed to the outside when the door 131 is open (entrance / exit 127). When the door 131 is open (entrance / exit 127), the front of the dust bag drawer 144 and the front of the detergent container 163 are exposed to the outside, as are the handles 144d of the dust bag drawer 144 and 163b of the detergent container 163. This configuration allows for easy access to the dust bag drawer 144 and the detergent container 163, while providing a neat appearance.

[0282] The rotation axis 131a of the door 131 can be configured at the lower end of the door frame 132. When the entrance 127 is open, the door 131 is configured parallel to the bottom surface, or is formed to tilt downwards as it gets closer to the front so that the end contacts the ground.

[0283] The door 131 may have a hinge portion for rotatably connecting to the door frame 132. A plurality of hinge portions may be arranged spaced apart along the axis of rotation 131a, and may be arranged at different intervals.

[0284] Additionally, the door 131 may have an auxiliary entrance channel 131b on the surface opposite the cover 110 when the entrance / exit 127 is closed. The auxiliary entrance channel 131b may be configured to enable the robot vacuum cleaner 200 to move stably toward the placement section 120 or the entrance / exit 127, and may be configured to tilt upwards as it gets closer to the rear.

[0285] Specifically, the auxiliary inlet channel 131b can be formed in the shape of a groove to allow the robotic vacuum cleaner 200 to move stably at an angle. The grooves formed in the auxiliary inlet channel 131b along the left and right directions can be arranged at equal intervals along the front and back directions. Such an auxiliary inlet channel 131b can be formed such that its width in the left and right directions becomes narrower towards the rear. Therefore, the closer the wheels 260 of the robotic vacuum cleaner 200 are to the mounting section 120 or the inlet / outlet 127, the more restricted their left and right movement is, thus guiding them to the correct position.

[0286] The auxiliary inlet channel 131b guides the wheel 260 to the wheel guide section 121ba disposed in the mounting section 120. A pair of auxiliary inlet channels 131b may be provided, and each may be disposed in a position continuous with a pair of wheel guide sections 121ba.

[0287] On the other hand, the door 131 can be driven according to whether the robot vacuum cleaner 200 approaches or starts moving, or according to the input of the door operation unit 133.

[0288] The door frame 132 may be equipped with an entry sensor 135 to detect the approach of the robotic vacuum cleaner 200. The entry sensor 135 may be configured in front of the enclosure 110 to detect the approach of the robotic vacuum cleaner 200. For example, the entry sensor 135 may be an IR sensor.

[0289] The entry sensor 135 can be configured on the upper front of the door frame 132. This maximizes the detection range. Alternatively, the entry sensor 135 can be positioned at the center of the entrance / exit 127 in the left-right direction. This allows the robot vacuum cleaner 200 to be guided in its entry direction via communication with the robot vacuum cleaner 200.

[0290] On the other hand, the position of the door 131 facing the entry sensor 135 can be formed in a cut-out shape, so that the entry sensor 135 can detect the front even when the door 131 is closed at the entrance 127. Alternatively, a viewing window can be provided at the position of the door 131 facing the entry sensor 135.

[0291] The door frame 132 may be equipped with a door operating part 133, which allows the door 131 to be rotated by the user.

[0292] The door operation unit 133 is disposed on the door frame 132 and may have at least one button for driving the door 131. The door operation unit 133 can rotate the door 131 regardless of the position or state of the robot vacuum cleaner 200. The door operation unit 133 may have a button for opening or closing the door 131, or may have a button for opening the door 131 and a button for closing the door 131, respectively.

[0293] The door operating unit 133 can be disposed inside the door frame 132. In addition, the door operating unit 133 can be configured to have at least one button exposed to the outside.

[0294] At this time, the button can be configured adjacent to the detergent tank 163 with the inlet / outlet as the reference. For example, the button can be configured on the upper side of the handle 163b of the detergent tank 163.

[0295] On the other hand, if door 131 closes entrance / exit 127, it also covers door operation section 133. In this case, door 131 is provided with external button sections 131c so that door operation section 133 can be operated even when entrance / exit 127 is closed. The number of external button sections 131c is the same as the number of buttons on door operation section 133, and they are respectively located facing the buttons. The external button sections 131c are formed of an elastically deformable material, so that pressure can be applied to the buttons when an external force is applied.

[0296] Door 131 can be rotated by door drive unit 134. As an example, door drive unit 134 may include door drive motor and drive gear unit.

[0297] The door drive motor can be disposed inside the cover 110, or in the upper space of the detergent tank 163. The door drive motor can also be disposed between the detergent tank 163 and the upper cover 113 of the cover 110. Alternatively, the door drive motor can be disposed in front of the space between the outer wall 111 and the mounting portion 120. That is, the door drive motor can be disposed adjacent to the door operation portion 133.

[0298] This improves space utilization and accessibility, thereby providing convenience to users.

[0299] The drive gear unit is configured to connect the door drive motor and the door 131 to transmit power. The drive gear unit transmits the driving force of the door drive motor to the door 131, causing the door 131 to rotate.

[0300] Dust collection section

[0301] Figures 12 to 25 A diagram is shown illustrating the dust collection section of a robotic vacuum cleaner base station according to an embodiment of the present invention.

[0302] Reference Figures 12 to 25 The dust collection unit 140 is described below.

[0303] 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 disposed inside the housing 110. The dust collection unit 140 can also be disposed outside the mounting portion 120. That is, the dust collection unit 140 can be disposed between the housing 110 and the mounting portion 120. For example, the dust collection unit 140 can be disposed on one side of the mounting portion 120 in the left-right direction.

[0304] The dust collection unit 140 may include a dust collection unit cover 141, a filter 142, a dust bag 143, a dust bag drawer 144, a dust collection motor 145, a dust collection motor cover 146, a first dust collection flow path 147, and a second dust collection flow path 148.

[0305] The dust collection unit cover 141 can form a space inside that can accommodate the filter 142, the dust bag 143, and the dust bag drawer 144.

[0306] The dust collection unit cover 141 may have a dust bag drawer 144 that can be extended outwards inside, and the dust bag drawer 144 can store dust bags 143. For example, the dust collection unit cover 141 may be formed into a rectangular tube shape with an open front, and the rear internal space may be connected to the first dust collection flow path 147 and the second dust collection flow path 148.

[0307] Dust inside the dust bin 220 can flow into the dust collection unit cover 141.

[0308] One side of the interior of the dust collection hood 141 can be connected to the first dust collection flow path 147, and the other side can be connected to the second dust collection flow path 148. In addition, if the dust collection hood 141 is combined with a dust bag 143, the dust bag 143 can be connected to the first dust collection flow path 147 inside the dust collection hood 141.

[0309] Specifically, the dust collection section cover 141 may have an inlet 141a communicating with the first dust collection flow path 147 and an outlet 141b communicating with the second dust collection flow path 148.

[0310] At this time, the inlet 141a can be positioned closer to the upper side than the outlet 141b. This allows air and dust flowing in through the inlet 141a to flow downwards, capturing the dust in the dust bag 143 before being discharged through the outlet 141b. During this process, because the air flows from top to bottom, it prevents air from flowing upwards or dust from scattering upwards.

[0311] On the other hand, in this embodiment, the outlet 141b can be configured at a position closer to the front than the inlet 141a. For example, the inlet 141a can be formed on the rear side of the dust collection shroud 141, and the outlet 141b can be formed on the lower side of the dust collection shroud 141. In this case, the outlet 141b can be configured at a position closer to the front than the rear side of the dust collection shroud 141.

[0312] On the other hand, the outlet 141b can be formed by combining the dust collection hood 141 and the dust bag drawer 144. In this case, the outlet 141b of the dust collection hood 141 can represent the same space as the outlet 144c of the dust bag drawer 144.

[0313] On the other hand, a dust bag detection unit 141c may be provided in the dust collection unit cover 141. The dust bag detection unit 141c may be disposed on the rear side of the dust collection unit cover 141. The dust bag detection unit 141c may be disposed on the rear side of the dust collection unit cover 141 toward the dust bag drawer 144.

[0314] The dust bag detection unit 141c can detect the dust bag 143. For example, the dust bag detection unit 141c can be a micro switch. The dust bag detection unit 141c can contact the dust bag 143 to detect the presence or absence of the dust bag 143. Specifically, the dust bag detection unit 141c can contact the loading / unloading part 143b of the dust bag 143 to detect the presence or absence of the dust bag 143.

[0315] According to the present invention, a dust bag detection unit 141c is provided in the dust collection unit cover, thereby having the effect of detecting that the dust bag 143 has been installed if the dust bag 143 is attached.

[0316] On the other hand, a sterilization module 150 can be integrated into the dust collection hood 141. For example, the dust collection hood 141 can have a hot air inlet for supplying hot air from the sterilization module 150 and a hot air exhaust outlet for discharging hot air. In this case, the hot air inlet and the hot air exhaust outlet can be formed on the rear side of the dust collection hood 141, and can be respectively arranged on the left and right sides of the rear side of the dust collection hood 141. Furthermore, the hot air inlet can be positioned closer to the ground than the hot air exhaust outlet. That is, the hot air inlet and the hot air exhaust outlet can be arranged at diagonal positions on the rear side of the quadrilateral-shaped dust collection hood 141. This maximizes the length of the hot air flow path.

[0317] As another example, the upper side of the dust collection unit cover 141 may be fitted with a sterilization module 150 that irradiates light into the interior of the dust collection unit cover 141. In this case, the light can be ultraviolet (UV-C).

[0318] The dust bag drawer 144 includes a dust bag drawer body 144a, an inlet 144b, an outlet 144c, a handle 144d, and a flow path forming part 144e.

[0319] The dust bag drawer body 144a can provide internal space for the dust bag 143 to be assembled. For example, the dust bag drawer body 144a can be formed as a box with an open upper side, and an inlet 144b can be formed on the rear side to communicate with the first dust collection flow path 147. In this case, the inlet 144b can communicate with the inlet 141a of the dust collection unit cover 141.

[0320] The upper side of the dust bag drawer body 144a can be connected to the first dust collection path 147 via the inlet 144b. The inlet 144b can be configured to guide the air flowing in the first dust collection path 147 into the interior of the dust bag 143. The inlet 144b can connect the first dust collection path 147 with the dust bag 143. Therefore, dust sucked in from the dust bin 220 of the robot vacuum cleaner 200 can move into the interior of the dust bag 143 via the first dust collection path 147, the inlet 141a of the dust collection cover 141, and the inlet 144b of the dust bag drawer 144.

[0321] The dust bag drawer 144 can communicate with the second dust collection path 148 through an outlet 144c formed on its lower side (bottom). The outlet 144c can be configured to direct air that has passed through the dust bag 143 to the second dust collection path 148. That is, the outlet 144c can be formed to communicate with the internal space formed by combining with the bottom surface of the flow path forming part 144e and the dust collection part cover 141.

[0322] At this time, the outlet 144c can be configured at a different height from the inlet 144b. The outlet 144c can be configured at a position lower than the inlet 144b, with the lower side (bottom) of the dust bag drawer 144 as a reference. The outlet 144c allows the internal space of the dust bag drawer 144 to communicate with the second dust collection path 148. Therefore, air that has been filtered of dust while passing through the dust bag 143 can move to the second dust collection path 148 via the outlet 144c.

[0323] On the other hand, in this embodiment, the outlet 144c can be configured to be located closer to the front than the inlet 144b. For example, the outlet 144c can be configured to be located closer to the handle 144d than the inlet 144b.

[0324] On the other hand, the dust bag drawer 144 forms a flow path for the air that has passed through the dust bag 143 to be discharged to the dust collection motor 145. That is, the dust bag drawer 144 includes a flow path forming part 144e that protrudes upward from the bottom surface of the dust bag drawer body 144a and forms a flow path between it and the dust collection cover 141.

[0325] The flow path forming portion 144e can be disposed on the lower side of the dust bag drawer body 144a, and can form at least a portion of the second dust collection flow path 148. A pair of opposing sidewalls of the flow path forming portion 144e can be formed by bending upward from the lower side (bottom) of the dust bag drawer body 144a, and the flow path forming portion 144e can be formed to be covered by the upper sidewall connecting the pair of sidewalls.

[0326] Therefore, at least a portion of the second dust collection flow path 148 can be formed by combining the flow path forming part 144e with the bottom surface of the dust collection part cover 141.

[0327] On the other hand, the flow path forming portion 144e can be formed along the length direction of the dust bag drawer 144. At this time, a discharge port 144c can be formed at one end of the flow path forming portion 144e along the length direction.

[0328] Therefore, the air flowing into the outlet 144c can flow backward along the length of the flow path forming part and then be discharged to the dust collection motor 145.

[0329] On the other hand, another part of the second dust collection flow path 148 can be the space formed by the combination of the dust collection motor support 146c and the lower cover 146b of the dust collection motor, which will be described later.

[0330] Therefore, in this embodiment, the first dust collection path 147 and the second dust collection path 148 can be formed at different heights. That is, the first dust collection path 147 and the second dust collection path 148 can be configured in a stacked structure. In this case, at least a portion of the first dust collection path 147 can be disposed above the second dust collection path 148.

[0331] Meanwhile, the first dust collection path 147 and the second dust collection path 148 can be formed on the other side of the dust collection unit cover 141. For example, the first dust collection path 147 can be formed on the rear side of the dust collection unit cover 141, and the second dust collection path 148 can be formed along the lower side of the dust collection unit cover 141.

[0332] In this way, the air flowing in from the upper rear side of the dust bag drawer 144 flows to the lower front side of the dust bag drawer 144 after passing through the dust bag 143, so that the air containing dust can be evenly diffused inside the dust bag 143, and dust can be prevented from accumulating in specific positions of the dust bag 143.

[0333] On the other hand, a handle 144d may be provided at the front of the dust bag drawer body 144a. The handle 144d may be configured to be gripped by a user. As an example, the handle 144d may be a groove-shaped recess formed from the front to the rear of the dust bag drawer body 144a.

[0334] Therefore, according to the present invention, the user can easily pull the dust bag drawer 144 forward (first direction) and then lift the dust bag 143 upward (second direction) to remove and replace the dust bag 143.

[0335] On the other hand, in this embodiment, the dust bag drawer 144 may also be provided with a gasket. The gasket may be disposed on the front periphery of the dust bag drawer 144. The gasket can airtightly seal the gap formed between the dust collection unit cover 141 and the dust bag drawer 144 when the dust bag drawer 144 is introduced into the dust collection unit cover 141.

[0336] On the other hand, a sensor through hole 144g can be formed in the dust bag drawer 144. The sensor through hole 144g can be formed to allow at least a portion of the dust bag detection part 141c of the dust collection unit cover 141 to pass through. For example, the sensor through hole 144g can be formed in a quadrilateral hole shape at a position opposite to the dust bag detection part 141c. Therefore, at least a portion of the dust bag detection part 141c can pass through the sensor through hole 144g and be disposed therein, and can contact the dust bag 143 when the dust bag 143 is engaged with the dust bag drawer 144.

[0337] The filter 142 can be installed in the dust bag drawer 144. The filter 142 can be configured at the outlet 144c of the dust bag drawer 144. That is, the filter 142 can be configured on the lower side of the dust bag drawer 144. Therefore, the filter 142 can be drawn out along with the dust bag drawer 144 when it is drawn out. Alternatively, the filter 142 can be configured closer to the lower side than the dust bag 143.

[0338] The filter 142 can filter out foreign objects from the air discharged after flowing through the internal space of the dust bag 143 and the dust bag drawer 144. In this way, the filter 142 can prevent foreign objects from flowing into the dust collection motor 145 and damaging the dust collection motor 145. For example, the filter 142 can be a pre-filter.

[0339] Dust bag 143 can refer to a dust bag that collects dust sucked from inside the dust bin 220 of the robot vacuum cleaner 200 using the dust collection motor 145.

[0340] The dust bag 143 can be detachably attached to the dust bag drawer 144.

[0341] At this time, the dust bag drawer 144 can be configured to be extended from the dust collection unit cover 141 in a first direction, and the dust bag 143 can be detachably attached to the dust bag drawer 144 in a second direction intersecting the first direction. For example, the dust bag drawer 144 can be configured to be extended from the front and rear of the dust collection unit cover 141, and the dust bag 143 can be detachably attached to the dust bag drawer 144 in the vertical direction.

[0342] Dust pack 143 can be detached from dust pack drawer 144 and discarded, and new dust pack 143 can be attached to dust pack drawer 144. That is, dust pack 143 can be defined as a consumable part.

[0343] The dust bag 143 includes a dust bag body 143a, a loading and unloading part 143b, a light-transmitting part 143c, and an air inlet part 143d.

[0344] The dust bag body 143a can capture dust. The dust bag body 143a can be configured to increase in volume to accommodate dust internally when the dust collection motor 145 generates suction. For this purpose, the dust bag body 143a 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 body 143a can be made of non-woven fabric and, based on the increased volume, can have a hexahedral shape corresponding to the shape of the dust bag drawer 144.

[0345] The loading and unloading part 143b can be attached to the dust bag body 143a and can be detachably attached to the rear side of the dust bag drawer 144 in a sliding manner. For example, the loading and unloading part 143b can be formed as a flat plate and attached to the rear side of the dust bag body 143a, and can be detachably attached to the dust bag connecting part disposed on the rear side of the dust bag drawer 144 in a sliding manner.

[0346] At this point, the loading / unloading section 143b can be formed as a quadrilateral plate. The vertical height and horizontal width of the loading / unloading section 143b can be greater than or equal to the vertical height and horizontal width of the rear side of the dust bag body 143a. This allows the user to hold the loading / unloading section 143b and easily attach it to the dust bag drawer 144.

[0347] On the other hand, according to the embodiment, the loading and unloading portion 143b in the form of a quadrilateral plate can be a shape in which two diagonally opposite corner portions are cut open. For example, the cut portion 143ba can be formed by cutting open two diagonally opposite corner portions of the loading and unloading portion 143b in a rectangular shape. This can be a position communicating with the flow path for the inflow and the outflow path of hot air for sterilization. In this way, the dust bag 143 can achieve sterilization by hot air.

[0348] With this configuration, the dust bag 143 can be joined along the vertical direction. Therefore, in a dust bag 143 where the horizontal length is greater than the vertical height, the volume of the structure required to install the dust bag 143 can be reduced. As a result, it has the effect of increasing the dust-collecting capacity within a limited space.

[0349] On the other hand, a stop 144bb can be formed in the loading / unloading section 143b. The stop 144bb can protrude from the upper end of the outer side surface (the side opposite to the dust bag drawer 144) of the loading / unloading section 143b toward the dust bag drawer 144. At this time, the stop 144bb can protrude in the form of a rib in the left-right direction (width direction). With the above configuration, when the dust bag 143 is attached to the dust bag drawer 144, the stop 144b can be locked by the upper end of the rear side surface of the dust bag drawer 144. Therefore, even if the dust bag 143 is attached to the dust bag drawer 144, a portion of the upper end of the loading / unloading section 143b can be exposed upwards, thereby providing the user with the convenience of grasping the stop 144b and lifting it upwards to separate the dust bag 143.

[0350] On the other hand, an inlet 143bc may be formed in the loading / unloading section 143b for dust to flow into the dust bin 220. The inlet 143bc may be configured to communicate with the inlet 144b of the dust bag drawer 144. Therefore, when the dust collection motor 145 is running, air and dust in the dust bin 220 can flow into the dust bag body 143a and be captured. The inlet 143bc may communicate with the inlet pipe 143db described later.

[0351] The light-transmitting portion 143c can be integrated with the dust bag body 143a, allowing light to penetrate into the interior of the dust bag body 143a. In this case, the light-transmitting portion 143c and the loading / unloading portion 143b can be disposed on the other side of the dust bag body 143a. For example, the light-transmitting portion 143c can be formed as a flat plate and integrated with the upper side of the dust bag body 143a, allowing light irradiated from the sterilization module disposed on the upper side of the interior of the dust collection unit cover to pass through.

[0352] At this time, the light-transmitting portion 143c can be formed into a quadrilateral plate shape. The light-transmitting portion 143c can be integrated with the loading / unloading portion 143b. Specifically, the light-transmitting portion 143c can be formed by bending and extending from the loading / unloading portion 143b. This provides the effect of stably supporting the light-transmitting portion 143c even when the loading / unloading portion 143b is attached to the dust bag drawer 144.

[0353] On the other hand, the light-transmitting portion 143c and the cutting portion 143ba can be selectively configured, or they can be provided simultaneously. This improves the hygiene of the dust bag 143.

[0354] A light-transmitting window 143ca is provided in the light-transmitting section 143c. The light-transmitting window 143ca can be formed of a material that allows light to pass through. Specifically, the light-transmitting window 143ca can be formed of a material that allows light, including ultraviolet light, to pass through. As an example, the light-transmitting window 143ca can be formed of a material that allows UV-C light to pass through.

[0355] The light-transmitting window 143ca can be positioned opposite the light source of the sterilization module 150 provided on the dust collection unit cover 141. Therefore, light emanating from the light source can pass through the light-transmitting window 143ca to sterilize the interior of the dust bag body 143a.

[0356] With this configuration, pests and microorganisms, including flour mites, present inside the dust bag 143 can be sterilized to improve hygiene.

[0357] On the other hand, an inlet 143bc for dust to flow into the dust bin 220 can be formed in the loading and unloading section 143b. The inlet 143bc can be configured to communicate with the inlet 144b of the dust bag drawer 144. Therefore, when the dust collection motor 145 is running, air and dust in the dust bin 220 can flow into the dust bag body 143a and be captured.

[0358] On the other hand, the dust bag 143 may also include an air inlet 143d inside the bag-shaped dust bag body 143a. The air inlet 143d may be positioned opposite the loading / unloading part 143b across the dust bag body 143a. The air inlet 143d may be connected to the loading / unloading part 143b across the dust bag body 143a. That is, if the loading / unloading part 143b is located on the rear outer side of the dust bag body 143a, the air inlet 143d may be located on the rear inner side of the dust bag body 143a. In this way, the shape of the rear portion of the bag-shaped dust bag body 143a can be supported, preventing damage to the connection between the dust bag body 143a and the loading / unloading part 143b, which could cause the bag portion of the dust bag body 143a to tear and scatter dust.

[0359] The air inlet 143d may include an air inlet plate 143da, an inlet pipe 143db, an inlet cover 143dc, and a guide wall 143dd.

[0360] The inflow section plate 143da can be formed in the form of a flat plate, with one side opposite to the loading and unloading section 143b to be combined with the loading and unloading section 143b and / or the dust bag body 143a, and the other side can protrude to form an inflow pipe 143db and a guide wall 143dd.

[0361] For example, the inflow section 143da can be formed into a quadrilateral flat plate shape, while the four corner parts can be formed into a curved surface shape. This configuration can prevent the corner parts from causing damage to the dust bag body 143a.

[0362] The inflow pipe 143db can protrude from the inflow section plate 143da and be formed into a cylindrical shape. At this time, the inflow pipe 143db can be formed along the outflow direction of the dust bag drawer 144. In this way, air can flow smoothly from the dust bin 220, which is located closer to the rear than the dust bag 143.

[0363] On the other hand, the protrusion height of the inlet pipe 143db does not need to be constant. For example, the closer the inlet pipe 143db is to the top in the vertical direction, the higher the protrusion height can be. In this way, the inlet cover 143dc can close the inlet pipe 143db with uniform surface pressure.

[0364] An inlet can be formed in the inflow pipe 143db, which can communicate with the inlet 143bc formed in the loading and unloading section 143b. Therefore, the inflow pipe 143db can guide the dust in the dust bin 220 into the dust bag body 143a.

[0365] The inlet cover 143dc allows the inlet to be opened and closed. The inlet cover 143dc can be formed in a shape with a diameter larger than that of the inlet pipe 143db.

[0366] The inlet cover 143dc includes a fixing part 143dca fixedly attached to the inlet plate 143da and an opening / closing part 143dcb that uses the suction of the dust collection motor 145 to open and close the inlet pipe. At this time, with the dust bag 143 attached to the dust bag drawer 144, the fixing part 143dca can be positioned closer to the lower side than the opening / closing part 143dcb.

[0367] With this configuration, when the dust collection motor 145 is running, the upper part of the inlet pipe 143db opens first, allowing air to flow into the upper part of the internal space of the dust bag 143. Therefore, the dust flowing into the dust bag 143 is prevented from concentrating directly below the inlet.

[0368] Additionally, the inlet cover 143dc can be formed of an elastic material. For example, the inlet cover 143dc can be formed of resin or rubber. Therefore, when the dust collection motor 145 is running, the opening and closing part 143dcb can rotate and open and close the inlet by the suction of the dust collection motor 145.

[0369] The guide wall 143dd can guide the flow direction of air passing through the inlet pipe 143db. A pair of guide walls 143dd can be formed by protruding from the inlet plate 143da. A pair of guide walls 143dd can be formed in the vertical direction of the inlet plate 143da.

[0370] At this time, an inflow pipe 143db and an inflow cover 143dc can be arranged between a pair of guide walls 143dd. At this time, the protrusion height of the pair of guide walls 143dd can be greater than the protrusion height of the inflow pipe 143db.

[0371] With the above configuration, a pair of guide walls 143dd can block the air flowing between the inlet pipe 143db and the inlet cover 143dc from spreading in the left and right directions, and guide the air to flow in front of the vacuum cleaner base station 100.

[0372] Therefore, through a pair of guide walls 143dd, the air flowing into the dust bag 143 can be evenly diffused throughout the dust bag 143.

[0373] The dust collection unit 140 may also include a dust collection module. The dust collection module can provide suction airflow to the dust collection flow path.

[0374] Specifically, the dust collection unit 140 may also include a dust collection motor 145 and a dust collection motor cover 146.

[0375] The dust collection motor 145 can generate suction on the dust collection flow paths 147 and 148. That is, the dust collection motor 145 can provide suction to draw dust from the dust bin 220 into the dust bag 143 disposed in the dust collection unit cover 141.

[0376] The dust collection motor 145 can be configured behind the dust collection unit cover 141. In this way, the dust collection motor 145 can provide suction power capable of sucking up dust from the dust bin 220 of the robot vacuum cleaner 200.

[0377] The dust collection motor 145 can generate suction by rotation. As an example, although not shown, the dust collection motor 145 includes a rotor and a stator that receive power and rotate relative to each other, and may include an impeller that rotates about a rotation axis as the rotor rotates. Therefore, suction can be generated by the rotation of the impeller.

[0378] One side of the dust collection motor 145 can be connected to the second dust collection flow path 148, and the other side can be connected to the return flow path 125a. When the dust collection motor 145 is driven, the air flowing in the second dust collection flow path 148 can flow into the interior of the dust collection motor housing 146. In addition, the air flowing into the interior of the dust collection motor housing 146 can flow in the return flow path 125a after passing through the dust collection motor 145.

[0379] On the other hand, in this embodiment, the rotation axis of the dust collection motor 145 can be configured in the vertical direction. In this case, the horizontal space occupied by the dust collection motor 145 can be minimized.

[0380] On the other hand, when the rotation axis of the dust collection motor 145 is arranged in a vertical direction, the side where air flows into the dust collection motor 145 and the side where air is discharged from the dust collection motor 145 can be arranged at different heights. Thus, the structure of the dust collection motor cover 146 can be formed.

[0381] The dust collection motor cover 146 can accommodate the dust collection motor 145. The dust collection motor cover 146 can be disposed behind the dust collection section cover 141. Alternatively, the dust collection motor cover 146 can be disposed behind the first dust collection flow path 147. Additionally, the dust collection motor cover 146 can be disposed behind the second dust collection flow path 148.

[0382] That is, taking the front-to-back direction of the robot vacuum base station 100 as a reference, the dust collection cover 141 can be positioned at the front, and a first dust collection flow path 147 and a second dust collection flow path 148 can be positioned behind the dust collection cover 141. Furthermore, the dust passage hole 123a can be positioned closer to the rear than the first dust collection flow path 147, and the dust collection motor cover 146 can be positioned closer to the rear than the second dust collection flow path 148. Additionally, the dust collection motor cover 146 can be positioned closer to the rear than the dust passage hole 123a.

[0383] Therefore, the dust collection unit 140 is arranged along the front-rear direction of the robot vacuum base station 100, thereby reducing the overall height.

[0384] In this embodiment, the dust collection motor cover 146 includes an upper dust collection motor cover 146a, a lower dust collection motor cover 146b, a dust collection motor support 146c, and a motor shock absorber 146d.

[0385] At this time, the dust collection motor 145 can be mounted on the dust collection motor support 146c. The upper cover 146a of the dust collection motor can be attached to the upper side of the dust collection motor support 146c, and the lower cover 146b of the dust collection motor can be disposed on the lower side of the dust collection motor 145. On the other hand, a motor vibration damper 146d can be attached between the dust collection motor support 146c and the upper cover 146a of the dust collection motor.

[0386] With this configuration, when the dust collection motor 145 is placed on the dust collection motor support 146c, the upper cover 146a of the dust collection motor can be assembled after the motor vibration damper 146d is combined, and the lower cover 146b of the dust collection motor can be assembled on the lower side of the cover 110.

[0387] Therefore, the components of the dust collection motor housing 146 can be assembled from the upper and lower sides of the dust collection motor 145, which has the effect of making assembly and repair operations easy.

[0388] The upper cover 146a of the dust collection motor can cover the upper side of the dust collection motor 145. The upper cover 146a of the dust collection motor may include a motor housing portion that houses a portion of the upper side of the dust collection motor 145 and an upper flow path forming portion that is connected to the motor housing portion and forms a flow path inside it.

[0389] The motor housing can be formed in a shape similar to a cylinder, but with the upper end blocked. Air discharged from the dust collection motor 145 can flow in the space between the motor housing and the dust collection motor 145, and can be discharged to the upper flow path forming part.

[0390] The upper flow path forming portion can be formed by extending radially outward from the outer peripheral surface of the motor housing. This allows the flow direction of the air discharged between the motor housing and the dust collection motor 145 to be guided. In addition, the upper surface of the upper flow path forming portion can be formed with a groove to accommodate at least a portion of the pipe or hose forming the first dust collection flow path 147.

[0391] With this configuration, at least a portion of the first dust collection flow path 147 can pass through the upper side of the upper flow path forming section.

[0392] The upper flow path forming section can form at least a portion of the return flow path 125a internally. Specifically, the space formed by the upper flow path forming section and the dust collection motor support section 146c can form a portion of the return flow path 125a.

[0393] The lower cover 146b of the dust collector motor can cover the lower side of the dust collector motor 145. The lower cover 146b of the dust collector motor can be attached to the lower side of the drawer 190. The lower cover 146b of the dust collector motor can include a lower cover portion disposed on the lower side of the dust collector motor 145 and a lower flow path forming portion connected to the lower cover portion and forming a flow path for air flowing into the dust collector motor 145.

[0394] The lower cover can be formed in the shape of a disc, but it is formed in such a way that the center of the disc protrudes towards the dust collection motor 145. With the above configuration, the upward flow of air flowing into the dust collection motor 145 can be guided.

[0395] The lower flow path forming section can be formed by extending radially outward from the lower cover. In this way, the flow of air flowing from the dust collection unit cover 141 into the dust collection motor 145 can be guided.

[0396] The lower flow path forming section can form at least a portion of the second dust collection flow path 148 internally. Specifically, the space formed by the lower flow path forming section and the dust collection motor support section 146c can form a portion of the second dust collection flow path 148.

[0397] The dust collection motor support 146c can support the dust collection motor 145.

[0398] The dust collection motor support 146c can be connected to various components forming the internal structure of the robotic vacuum cleaner base station 100. The dust collection motor support 146c can be connected to the dust collection unit cover 141. The dust collection motor support 146c can be connected to the inner wall 124 or the connecting wall 123 of the mounting part 120. In this way, the dust collection motor support 146c can provide a supporting force capable of supporting the dust collection motor 145.

[0399] The dust collection motor support 146c can be combined with the upper dust collection motor cover 146a and the lower dust collection motor cover 146b to form a return flow path 125a and a second dust collection flow path 148, respectively. Specifically, the second dust collection flow path 148 can be formed on the lower side of the dust collection motor support 146c, and the return flow path 125a can be formed on the upper side of the dust collection motor support 146c.

[0400] By stacking multiple flow paths on top of each other, space efficiency within a limited height can be maximized.

[0401] As a result of this configuration, air flowing in from inside the dust bin 220 can pass between the dust collection motor support 146c and the lower cover 146b of the dust collection motor and flow into the dust collection motor 145, and then pass through the dust collection motor 145 and be discharged between the dust collection motor support 146c and the upper cover 146a of the dust collection motor.

[0402] Therefore, according to the present invention, while the dust collection motor 145 is arranged in the vertical direction, two separate flow paths can be formed by the dust collection motor support 146c. Thus, the flow paths required for dust collection can be stacked within a limited height and lateral space, and the stacked flow paths allow air to flow in and out, thereby maximizing space efficiency.

[0403] On the other hand, the motor shock absorber 146d can be combined between the dust collection motor support 146c and the dust collection motor 145 to elastically support the dust collection motor 145.

[0404] The motor shock absorber 146d can be connected between the dust collector motor support 146c and the upper cover 146a of the dust collector motor. That is, the upper side of the motor shock absorber 146d can be connected to the upper cover 146a of the dust collector motor, and the lower side of the motor shock absorber 146d can be connected to the dust collector motor support 146c. With this configuration, if the dust collector motor support 146c is connected to the upper cover 146a of the dust collector motor, the motor shock absorber 146d can be fixed between the dust collector motor support 146c and the upper cover 146a of the dust collector motor, thereby ensuring support force.

[0405] On the other hand, the motor shock absorber 146d can be formed from a flexible material.

[0406] Therefore, according to the present invention, as the dust collection motor 145 is arranged in a vertical direction, a vibration damper 146d is provided at its lower part, thereby having the effect of reducing vibration and noise caused by the operation of the dust collection motor 145.

[0407] Therefore, according to the present invention, the shock absorber 146d makes the return flow path 125a formed between the dust collection motor support 146c and the upper cover 146a of the dust collection motor airtight, thereby having the effect of preventing air leakage.

[0408] On the other hand, the dust collection unit 140 may also include dust collection flow paths 147 and 148. The dust collection flow path can refer to the flow path through which air drawn in through the dust passage hole 123a flows to the dust collection motor 145 via the dust bag.

[0409] Specifically, the dust collection path may include a first dust collection path 147 and a second dust collection path 148. If the robot vacuum cleaner 200 is combined with the robot vacuum cleaner base station 100, and the dust is connected to the dust bin 220 of the robot vacuum cleaner 200 through the hole 123a, then the first dust collection path 147 connects the dust bin 220 with the internal space of the dust collection part cover 141, and the second dust collection path 148 connects the internal space of the dust collection part cover 141 with the internal space of the dust collection motor cover 146.

[0410] The first dust collection path 147 connects the dust bin 220 of the robotic vacuum cleaner 200 to the internal space of the dust collection cover 141. The first dust collection path 147 also connects the dust passage hole 123a of the placement part 120 to the internal space of the dust collection cover 141. The first dust collection path 147 can be formed in a direction intersecting the vertical direction. For example, the first dust collection path 147 can be formed in a nearly horizontal direction. The first dust collection path 147 can be a space formed rearward from the dust passage hole 123a, or it can be a path that bends laterally from the dust passage hole 123a to allow dust and air to flow. Through the first dust collection path 147, dust in the dust bin 220 of the robotic vacuum cleaner 200 can move into the internal space of the dust collection cover 141.

[0411] The second dust collection path 148 can connect the internal space of the dust collection unit cover 141 with the internal space of the dust collection motor cover 146. The second dust collection path 148 can be formed in a direction that intersects the vertical direction. For example, the second dust collection path 148 can be formed in a near-horizontal direction.

[0412] In this invention, the first dust collection path 147 and the second dust collection path 148 can be formed at different heights. That is, the first dust collection path 147 and the second dust collection path 148 can be configured in a stacked structure. At least a portion of the first dust collection path 147 can be disposed above the second dust collection path 148.

[0413] By configuring multiple flow paths in a near-horizontal direction, the overall height can be reduced. At the same time, by stacking multiple flow paths, the left-right width and overall volume of the robot vacuum base station 100 can be minimized.

[0414] The air return section 125 can direct the air expelled from the dust collection motor 145 to the robot vacuum cleaner 200.

[0415] The air return section 125 can be composed of a return flow path 125a and an air return port 125b.

[0416] The return flow path 125a provides a flow path for air discharged from the dust collection motor 145. The return flow path 125a can be formed by the dust collection motor housing 146 and the base 121. Specifically, one side of the return flow path 125a can be a space formed by the combination of the dust collection motor support 146c and the upper housing 146a of the dust collection motor. The other side of the return flow path 125a can be disposed inside the base body 121a. For example, the return flow path 125a can be a space formed between the upper and lower sides of the base body 121a.

[0417] Therefore, one side of the return flow path 125a can pass through the dust collection motor cover 146. Additionally, the other side of the return flow path 125a can pass through the lower side of the base 121. At the same time, at least a portion of the return flow path 125a can be configured to be closer to the lower side than the robotic vacuum cleaner 200 positioned on the upper side of the base body 121a.

[0418] The return flow path 125a can be connected to the flow path of the dust collection motor 145. One end of the return flow path 125a can communicate with the internal space of the dust collection motor housing 146, and the other end of the return flow path 125a can communicate with the air return port 125b.

[0419] The return flow path 125a can be a flow path formed in a direction that intersects the vertical direction. For example, the return flow path 125a can be a flow path formed in a horizontal direction inside the cover 110.

[0420] At this time, at least a portion of the return flow path 125a can be configured to be positioned closer to the lower side than the first dust collection flow path 147. That is, the return flow path 125a can be configured to pass through the lower side of the first dust collection flow path 147. Therefore, the flow directions of the air flowing in the first dust collection flow path 147 and the air flowing in the return flow path 125a can intersect each other on the horizontal plane.

[0421] Furthermore, at least a portion of the return flow path 125a can be configured to be positioned closer to the upper side than the second dust collection flow path 148. That is, the return flow path 125a can be configured to pass through the upper side of the second dust collection flow path 148.

[0422] By configuring (layering) the first dust collection path 147, the second dust collection path 148, and the return path 125a vertically within a limited height, space efficiency can be maximized.

[0423] In addition, by using the remaining space inside the base 121 to form the return flow path 125a, the height of the robot vacuum base station 100 can be prevented from increasing. Since no additional space is needed to form the flow path, space efficiency can be maximized.

[0424] An air return port 125b can be formed on the base 121. The air return port 125b can also be formed on the agitator housing 121d. In this case, the suction unit 211 of the robotic vacuum cleaner 200 can be disposed on the upper side of the agitator housing 121d. Therefore, the return flow path 125a can discharge air to the lower side of the suction unit 211, and the air passing through the return flow path 125a can flow into the suction unit 211 disposed directly above it.

[0425] Therefore, the return flow path 125a of this embodiment of the invention can direct the air discharged from the dust collection motor 145 to the suction section 211 of the sweeping robot 200.

[0426] The return flow path 125a directs the air expelled from the dust collection motor 145 to the suction section 211 of the robot vacuum 200 instead of expelling it to the outside, thus creating a structure that allows air to continuously circulate between the robot vacuum 200 and the robot vacuum base station 100. Therefore, the hot air expelled from the dust collection motor 145 is not discharged into the cabinet 2, but instead flows back into the interior of the robot vacuum 200 and circulates, thereby preventing damage to the interior of the cabinet 2.

[0427] Air passing through the dust collection motor 145 can be discharged into the receiving space S through the air return port 125b. The air discharged into the receiving space S can then flow back into the suction section 211 using the suction force of the dust collection motor 145. Therefore, air drawn into the dust bin 220 using the suction force of the dust collection motor 145 can flow sequentially through the dust passage hole 123a, the first dust collection flow path 147, the dust collection section cover 141, the second dust collection flow path 148, the dust collection motor 145, the return flow path 125a, and the air return port 125b before being discharged into the receiving space S.

[0428] At this time, if the suction motor (not shown) of the robotic vacuum cleaner 200 is driven, the dust collection motor 145 can also be driven. The air discharged through the air return port 125b is sucked into the suction unit 211 by the suction of the dust collection motor 145 and the suction motor (not shown), thus improving the dust collection efficiency.

[0429] Sterilization module

[0430] The robotic vacuum cleaner base station 100 of one embodiment of the present invention may further include a sterilization module 150. The sterilization module 150 may be integrated with the dust collection unit cover 141.

[0431] In a robotic vacuum cleaner base station 100 according to an embodiment of the present invention, a sterilization module 150 can sterilize a dust bag 143. Specifically, the sterilization module 150 can irradiate light onto the dust bag 143.

[0432] The sterilization module 150 may include a light source that emits sterilization light and a protective plate disposed below the light source and protecting the light source.

[0433] Here, the light source may include at least one light-emitting diode (LED) capable of emitting bactericidal light with bactericidal power capable of removing bacteria. The bactericidal light emitted by the light source may have different wavelengths depending on the type of LED.

[0434] As an example, a light source could be a light-emitting diode that emits ultraviolet light in the UV-C wavelength range. Ultraviolet light can be classified according to wavelength into UV-A (315nm–400nm), UV-B (280nm–315nm), and UV-C (200nm–280nm). Among them, ultraviolet light in the UV-C region can inhibit the reproduction of microorganisms by disrupting the double helix of their DNA.

[0435] On the other hand, the sterilization module 150 can be disposed on the upper inner side of the dust collection unit cover 141. The sterilization module 150 can irradiate light downwards. In this way, even if there is dust inside the dust bag 143, the dust will settle downwards under the action of gravity, so light can be irradiated into the dust bag 143 regardless of the presence of dust.

[0436] On the other hand, the sterilization module 150 of another embodiment of the present invention can supply hot air to the dust bag 143.

[0437] The sterilization module 150 may include: a fan that generates airflow; a heater that supplies heat to the air flowing into the dust collection hood 141; and a duct that directs hot air into the dust collection hood 141.

[0438] Hot air supplied from the sterilization module 150 can pass through the dust collection unit cover 141 and the dust bag drawer 144 to supply heat to the dust bag 143, thereby sterilizing pests and microorganisms.

[0439] Cleaning cloth washing section

[0440] Reference Figures 26 to 30 The following is a description of the mop washing unit 160 of the robot vacuum cleaner base station 100 according to an embodiment of the present invention.

[0441] The robot vacuum cleaner base station 100 of this embodiment may include a mop washing unit 160. The mop washing unit 160 may supply washing water to the mop 242 of the robot vacuum cleaner 200 attached to the mounting unit 120 to wash the mop 242 and discharge the wastewater after washing the mop 242.

[0442] The cloth washing unit 160 may include a washing water supply unit that mixes a liquid containing detergent and clean water and then dispenses it onto the upper side of the washing plate 122. The washing water supply unit may include a regulator 161, a mixing chamber 162, a detergent tank 163, a branch flow path 164, and a washing water nozzle 165.

[0443] At this time, the detergent tank 163 and the wastewater tank 166 can be accommodated in the space formed between the inner wall 124 and the outer wall 111 of the cover. The detergent tank 163 can be disposed on the lower side of the space between the inner wall 124 and the outer wall 111 of the cover, and the wastewater tank 166 can be disposed on the upper side of the detergent tank 163.

[0444] The water supply pipe of the kitchen cabinet 2 can be connected to the regulator 161 to regulate the flow rate supplied from the water supply pipe. In addition, a portion of the purified water after passing through the regulator 161 can be supplied to the water tank 230 of the robot vacuum cleaner 200 through the water supply nozzle 123c, and another portion can be supplied to the mixing chamber 162.

[0445] Additionally, the detergent-containing liquid stored in the detergent tank 163 can be supplied to the mixing chamber 162 using the fluid power of a pump. The detailed structure of the detergent tank 163 will be described later.

[0446] The mixing chamber 162 has a space for separately flowing in and mixing liquid containing detergent and purified water, and can discharge washing water containing a mixture of detergent and purified water. Such a mixing chamber 162 may have a purified water inlet 162a, a detergent inlet 162b, and a branch flow path connection port 162c.

[0447] The mixing chamber 162 can be located inside the housing 110, and can be positioned further rearward than the mounting section 120. In this case, a flow path 161a for purified water to flow from the regulator 161 can be connected to the purified water inlet 162a. Additionally, a flow path 163a for liquid containing detergent to flow from the detergent tank 163 can be connected to the detergent inlet 162b. Therefore, the pumps of the regulator 161 and the detergent tank 163 can operate for a predetermined time, causing a preset amount of purified water and detergent to flow into the mixing chamber 162.

[0448] On the other hand, the branch flow path connection port 162c can be connected to the branch flow path 164. The branch flow path 164 can supply washing water, which is a mixture of clean water and detergent, to a pair of washing water nozzles 165.

[0449] The branch flow path 164 can be configured as a pipe branching into two. In this case, either end of the branch can be connected to either of the pair of washing water nozzles 165, and the other end of the branch can be connected to the other of the pair of washing water nozzles 165.

[0450] The washing water nozzles 165 can be arranged in pairs, spaced apart. In this case, the pair of washing water nozzles 165 can be arranged in symmetrical positions.

[0451] Additionally, the washing water nozzle 165 can be connected to the branch flow path 164 to allow washing water to flow into the interior and be discharged onto the washing plate 122. The washing water nozzle 165 can discharge washing water onto the top surface of the washing plate 122 through the washing water discharge outlet 165a. The washing water discharge outlet 165a can open in a direction opposite to the top surface of the cloth 242 placed on the washing plate 122. More specifically, the washing water discharge outlet 165a formed in the washing water nozzle 165 can discharge washing water onto the washing protrusion 122a of the washing plate 122.

[0452] The washing water nozzle 165 can be installed in the nozzle mounting wall 123d connected to the connecting wall 123. The washing water nozzle 165 can be located at a position higher than the uppermost end of the washing plate 122 to allow the washing plate 122 to be installed and removed. Thus, when the washing plate 122 is installed or the drawer 190 is extended, the washing plate 122 and the washing tank 128 will not collide with the washing water nozzle 165, and a washing water discharge space can be provided between the nozzle mounting wall 123d and the washing plate 122.

[0453] Furthermore, the washing water nozzle 165 can be positioned vertically upwards from a position spaced apart from the center of the washing protrusion 122a in the width direction. Specifically, during the washing process of the cloth 242, if the rotation direction of the cloth 242 is taken as one direction, the washing water nozzle 165 can be positioned in another direction spaced apart from the center of the washing protrusion 122a in the width direction. The washing water outlet 165a can be positioned between the protrusion 122aa and the washing rib 122ab, and spaced apart from the protrusion 122aa in the opposite direction to the rotation direction of the cloth 242. With this configuration, the washing water can flow along the center of the washing protrusion 122a in the width direction.

[0454] The detergent container 163 includes a detergent container body 163a, a handle 163b, and a detergent container track 163c.

[0455] The detergent container body 163a can provide space for storing liquid containing detergent. For example, the detergent container body 163a can be formed as a box shape with an open top.

[0456] A handle 163b may be provided at the front of the detergent container body 163a. ​​The handle 163b may be configured to be gripped by a user. For example, the handle 163b may be recessed from the front to the rear of the detergent container body 163a.

[0457] With this configuration, when the user grasps the handle 163b and pulls it forward, the detergent tub body 163a can also be pulled forward and extended. Therefore, according to the present invention, the user can easily pull the detergent tub 163 forward and then dispense detergent.

[0458] The detergent container body 163a may have a detergent container track 163c. The detergent container track 163c may guide the movement of the detergent container body 163a.

[0459] For example, the detergent bucket track 163c can be formed as a groove or rib on the left and right sides of the detergent bucket body 163a along the front and back directions.

[0460] With the above configuration, when the user attaches the detergent container 163 to the cover 110, the detergent container 163 can be attached to the correct position to prevent washing water leakage.

[0461] On the other hand, although not shown in the figure, a track can be formed on the cover 110 corresponding to the detergent tub track 163c. The aforementioned track can be formed in a shape and position corresponding to the detergent tub track 163c.

[0462] On the other hand, an inlet 163aa can be formed in the detergent tank body 163a. ​​Liquid containing detergent can be injected into the interior of the detergent tank body 163a through the inlet 163aa.

[0463] The detergent container 163 may include a filling cap 163d. The filling cap 163d can open and close the filling port 163aa.

[0464] Inlet 163aa can be located at the upper front of the detergent container body 163a. ​​Inlet 163aa can be configured adjacent to handle 163b. With this configuration, the user can refill detergent through inlet 163aa after separating the filling cap 163d with only a portion of the detergent container body 163a protruding from the detergent container insertion port 132b.

[0465] The filling cap 163d can be detachably attached to the detergent container body 163a, and can have a sealing portion 163db that protrudes from one side and is inserted into the filling port 163aa. The sealing portion 163db can be inserted into and support the filling port 163aa to achieve a seal.

[0466] Additionally, the filling cap 163d may have a cap handle 163da formed by a portion of its edge protruding outwards. The cap handle 163da may be configured to protrude outwards from the detergent container body 163a.

[0467] Furthermore, the filling cap 163d can be configured to remain attached to the detergent container body 163a even after being detached from it and opening the filling port 163aa. That is, to prevent the filling cap 163d from being lost, it can have an anti-loss lanyard 163dc. One end of the anti-loss lanyard 163dc can be integrally formed with the filling cap 163d, and the other end has a connecting opening 163dd for insertion into the inside of the detergent container body 163a.

[0468] An anti-loss lanyard insertion portion 163ab is provided in the detergent container 163. The anti-loss lanyard insertion portion 163ab is formed to be smaller than the connecting opening 163dd and larger than the cross-section of the anti-loss lanyard 163dc. That is, if the anti-loss lanyard insertion portion 163ab is a circular hole shape, the diameter of the anti-loss lanyard insertion portion 163ab can be formed to be smaller than the diameter of the connecting opening 163dd; if the cross-section of the anti-loss lanyard 163dc is circular, the diameter of the anti-loss lanyard insertion portion 163ab can be formed to be larger than the diameter of the cross-section of the anti-loss lanyard 163dc.

[0469] Additionally, the detergent container body 163a may be provided with a cap mounting portion 163ac and a handle mounting portion 163ad to allow the filling cap 163d to be assembled into the correct position. The cap mounting portion 163ac may be formed by a step between the periphery of the inlet 163aa and the upper side of the detergent container body 163a, and may be configured for inserting the filling cap 163d. The handle mounting portion 163ad may be formed by expanding one side of the cap mounting portion 163ac, and may be configured for inserting the cap handle 163da. In this case, the position and shape of the handle mounting portion 163ad and the cap handle 163da are correspondingly arranged so that the filling cap 163d is in the correct position. With this configuration, if the filling cap 163d is attached to the detergent container body 163a, the cap handle 163da is configured to protrude outward from the detergent container body 163a, so that the user can easily detach or attach the filling cap 163d.

[0470] Drainage structure utilizing two air pumps

[0471] Figure 31 This is a top view of the wastewater tank of the robot vacuum cleaner base station used to illustrate an embodiment of the present invention. Figure 32 This is a diagram illustrating the wastewater tank and cleaning tank of the robot vacuum cleaner base station according to an embodiment of the present invention. Figure 33 This is a front view of the rear side of the wastewater tank of the sweeping robot used to illustrate an embodiment of the present invention.

[0472] Reference Figures 31 to 33 The wastewater tank 166 of the sweeping robot base station 100 of the present invention is described below.

[0473] Wastewater tank 166 provides space for storing water used to wash dishcloths 242. Washing water ejected onto the top surface of washing plate 122 can be discharged via through hole 122b after washing of dishcloths 242 has finished, descending along the incline of washing plate 122. Washing water passing through through hole 122b can accumulate in washing tank 128.

[0474] The shape of the wastewater tank 166 is described in detail below. The wastewater tank 166 can be housed inside the enclosure 110 and can be positioned on the right side of the cleaning tank 128. The main body of the wastewater tank 166 can have a cuboid shape extending along the front-rear direction of the enclosure 110. A wastewater inlet 166c, a wastewater outlet 167a, and a water level sensor 168 can be disposed on the inner rear side of the wastewater tank 166. Furthermore, a wastewater inlet pipe and a wastewater outlet pipe can be connected to the rear side of the wastewater tank 166.

[0475] Furthermore, the wastewater tank 166 can be configured such that its rear width is greater than its front width. This provides space on the rear side of the wastewater tank 166 for arranging various components. Additionally, the width of the wastewater tank 166 can correspond to the shape of the cleaning trough 128 disposed on the side. For example, the cleaning trough 128 can have a semi-circular structure that narrows towards the rear. Thus, the wastewater tank 166 can be configured such that its width increases towards the rear.

[0476] On the other hand, the sewage tank 166 may include a protrusion 166f extending forward from the main body of the sewage tank 166. The protrusion 166f may communicate with the interior of the sewage tank 166 to additionally store sewage. A sewage discharge pump 167b may be disposed on the upper part of the protrusion 166f. With this configuration, the limited space inside the enclosure 110 can be used more efficiently.

[0477] The wall 128b of the cleaning tank may protrude to form a wastewater suction nozzle 166a. The opening of the wastewater suction nozzle 166a may be configured to face the bottom of the cleaning tank 128. Washing water accumulated in the cleaning tank 128 can flow into the wastewater suction flow path 166b through the wastewater suction nozzle 166a, and then flow into the wastewater tank 166 after passing through the wastewater suction flow path 166b. That is, the liquid that has passed through the washing plate 122 can flow along the cleaning tank 128 and be discharged through the wastewater suction nozzle 166a.

[0478] Liquid flowing in through the sewage suction nozzle 166a can move towards the sewage tank 166 through the sewage suction flow path 166b. That is, water in the cleaning tank 128 can move towards the sewage tank 166 through the sewage suction flow path 166b. The sewage suction flow path 166b can be formed in the sewage suction pipe, with a sewage suction nozzle 166a formed at one end of the sewage suction pipe and a sewage inlet 166c formed in the sewage tank 166 at the other end of the sewage suction pipe. The sewage suction pipe can be connected to the rear side of the sewage tank 166. In this case, the sewage suction pipe can be configured to pass under the external gas supply module 171. That is, the sewage suction flow path 166b can be configured under the external gas supply module 171. Alternatively, the sewage suction flow path 166b can be configured under the external gas supply flow path 171a.

[0479] Water that has passed through the sewage intake flow path 166b can flow into the sewage tank 166 through the sewage inlet 166c. The sewage inlet 166c can be formed on the rear side of the sewage tank 166. Furthermore, the sewage inlet 166c can be positioned closer to the top than the sewage outlet 167a described later. The diameter of the sewage inlet 166c can be smaller than the diameter of the sewage outlet 167a.

[0480] On the other hand, wastewater can flow in simultaneously with the start of washing the mop 242 of the robotic vacuum cleaner 200. The washed water can first be stored in the washing tank 128 and then flow into the wastewater tank 166. Conversely, since wastewater discharge begins after the water level in the wastewater tank 166 reaches a predetermined level, it needs to be discharged at a faster rate than the wastewater inflow rate. To this end, by reducing the diameter of the wastewater inlet 166c and forming a larger diameter wastewater outlet 167a, the inflow and outflow rates of wastewater per unit time can be kept constant.

[0481] Furthermore, in the robotic vacuum cleaner base station 100 of the present invention, the wastewater inlet 166c can be configured at a position higher than the height of the wastewater suction nozzle 166a relative to the ground. Under the influence of gravity, the liquid in the wastewater tank 166 can flow back into the cleaning tank 128. The present invention can prevent backflow into the cleaning tank 128 by means of a check valve 166d or a water level detection sensor 168.

[0482] On the other hand, the sewage inlet 166c can be equipped with a check valve 166d that can be opened and closed. The check valve 166d can be opened when water flows into the sewage tank 166 and closed when water does not flow into the sewage tank 166. As an example, the check valve 166d can be opened when the sewage suction pump 166e is running. As another example, the check valve 166d can be closed when the water level in the sewage tank 166 reaches the height of the second sensor 168b.

[0483] The washing water accumulated in the washing tank 128 can be supplied to the wastewater tank 166 using the wastewater suction pump 166e. The wastewater suction pump 166e is connected to the wastewater tank 166 via a nozzle. The wastewater suction pump 166e can create a negative pressure in the wastewater tank 166. If a negative pressure is created in the wastewater tank 166, the liquid accumulated in the washing tank 128 can flow into the wastewater tank 166. At this time, the check valve 166d of the wastewater inlet 166c can be in an open state.

[0484] The sewage suction pump 166e can be configured in the same direction as the side of the sewage tank 166 where the sewage inlet 166c is formed. As an example, the sewage inlet 166c can be formed on the rear side of the sewage tank 166, and the sewage suction pump 166e can be configured behind the sewage tank 166.

[0485] On the other hand, the sewage suction pipe can be connected to the rear side of the sewage tank 166. If the sewage suction pump 166e creates a negative pressure in the sewage tank 166, the liquid flowing into the sewage inlet 166c can be discharged from the rear side of the sewage tank 166 to the front.

[0486] As an example, the sewage suction pump 166e can be configured behind the sewage tank 166. That is, the sewage suction pump 166e can be configured in the opposite direction to the discharge direction of the liquid flowing into the sewage inlet 166c. With this configuration, backflow of liquid into the sewage suction pump 166e can be prevented, allowing the liquid to flow smoothly into the sewage tank 166.

[0487] The following describes the configuration for discharging wastewater from the wastewater tank 166 into the drain pipe 25 of the kitchen cabinet 2.

[0488] Water in the wastewater tank 166 can be discharged to the drain pipe 25 of the kitchen cabinet 2 through the wastewater discharge path 167. One end of the wastewater discharge path 167 can be connected to the wastewater tank 166, and the other end can be connected to the drain pipe 25. The wastewater discharge path 167 can be formed in the wastewater discharge pipe, and a wastewater outlet 167a can be formed at one end of the wastewater discharge pipe, while the other end of the wastewater discharge pipe can be connected to the drain pipe 25. At this time, the washing water stored in the wastewater tank 166 can be discharged to the drain pipe 25 after flowing through the wastewater discharge path 167 using the wastewater discharge pump 167b.

[0489] Water stored in the wastewater tank 166 can be discharged to the outside through the wastewater outlet 167a. The wastewater outlet 167a can be formed on the rear side of the wastewater tank 166. Furthermore, the wastewater outlet 167a can be positioned closer to the lower side than the wastewater inlet 166c. The diameter of the wastewater outlet 167a can be larger than the diameter of the wastewater inlet 166c. The wastewater outlet 167a can communicate with the wastewater discharge path 167. Liquid in the wastewater tank 166 can flow into the wastewater discharge path 167 through the wastewater outlet 167a. Liquid passing through the wastewater discharge path 167 can be discharged into the drain pipe 25.

[0490] The water in the sewage tank 166 can be discharged to the drain pipe 25 of the kitchen cabinet 2 through the sewage discharge pump 167b.

[0491] The wastewater discharge pump 167b can be an air pump. The wastewater discharge pump 167b can be connected to the wastewater tank 166 via a nozzle. The wastewater discharge pump 167b can apply air pressure to the wastewater tank 166. The wastewater discharge pump 167b can create positive pressure in the wastewater tank 166, causing the liquid inside the wastewater tank 166 to be discharged to the outside.

[0492] When the sewage discharge pump 167b is an air pump, there is no need to worry about impurities clogging the sewage tank 166 since the liquid does not pass directly through the pump.

[0493] Furthermore, the air pump reduces positional restrictions on the wastewater tank 166. Specifically, due to the influence of gravity and position, the performance of a centrifugal pump may decrease when it is located far from or at a high position relative to the wastewater tank 166. Conversely, since the air pump supports fluid movement by regulating pressure, wastewater can move smoothly even if the wastewater tank 166 is far from the air pump or at a specific height, thus allowing for free setting of the wastewater tank 166's position.

[0494] Alternatively, two pumps, sewage suction pump 166e and sewage discharge pump 167b, can be used to independently handle the liquid inflow and outflow from sewage tank 166. This reduces the risk of leakage and pressure loss from sewage tank 166. Furthermore, by preventing wear on each pump, its lifespan can be extended.

[0495] The sewage discharge pump 167b can be positioned in the opposite direction to the side of the sewage tank 166 where the sewage outlet 167a is formed. For example, the sewage outlet 167a can be formed on the rear side of the sewage tank 166, and the sewage discharge pump 167b can be positioned on the front of the sewage tank 166. More specifically, the sewage discharge pump 167b can be positioned on the top surface of the protrusion 166f formed on the front of the sewage tank body.

[0496] On the other hand, since the sewage discharge pump 167b is located in front of the sewage tank 166, it can push the liquid in the sewage tank 166 from front to back. At this time, with the sewage outlet 167a located in the opposite direction to the sewage discharge pump 167b, the liquid in the sewage tank 166 can be smoothly discharged to the outside.

[0497] In addition, the sewage discharge pump 167b can operate based on the water level detected by the water level detection sensor 168.

[0498] The wastewater tank 166 of the robot vacuum cleaner base station 100 according to an embodiment of the present invention may include a water level detection sensor 168.

[0499] The water level sensor 168 can measure the water level in the wastewater tank. The water level sensor 168 can be configured on the inner rear side of the wastewater tank 166.

[0500] A plurality of water level detection sensors 168 may be formed. Each water level detection sensor 168 may include a first sensor 168a and a second sensor 168b located at a higher position than the first sensor 168a above the ground. That is, the first sensor 168a and the second sensor may be configured at different heights from each other.

[0501] On the other hand, the rear side of the sewage tank 166 may be equipped with a sewage inlet 166c for liquid inflow, a sewage outlet 167a for liquid discharge, a first sensor 168a, and a second sensor 168b.

[0502] The first sensor 168a can be located at a position higher than the lowest point of the sewage outlet 167a relative to the ground. Additionally, the second sensor 168b can be configured at the same height as or lower than the lowest point of the sewage inlet 166c relative to the ground.

[0503] Since the second sensor 168b can be positioned at the same height as or lower than the lowest point of the sewage inlet 166c relative to the ground, backflow of liquid into the sewage inlet 166c can be prevented. Furthermore, since the check valve 166d can close the sewage inlet 166c, backflow of liquid into the sewage inlet 166c can also be prevented.

[0504] In addition, since the first sensor 168a can be located at a position higher than the lowest point of the sewage outlet 167a relative to the ground, the idling time can be reduced even when the sewage discharge pump 167b has a low discharge efficiency, thereby achieving the effect of efficient energy use.

[0505] The following describes how the sewage suction pump 166e and the sewage discharge pump 167b operate based on the water level detected by the water level detection sensor 168.

[0506] First, if the rags are washed, water may accumulate in the washing tank 128. At this time, the wastewater suction pump 166e can be operated to create negative pressure in the wastewater tank 166. The liquid accumulated in the washing tank 128 can then flow into the wastewater tank 166.

[0507] At this time, the water level in the sewage tank 166 rises, and the water level detection sensor 168 can detect the water level in the sewage tank. If the water level in the sewage tank 166 reaches the level of the first sensor 168a, the sewage can be discharged.

[0508] For example, if the water level in the sewage tank 166 reaches the height of the first sensor 168a, the sewage discharge pump 167b can operate.

[0509] As another example, if the water level in the sewage tank 166 reaches the height of the second sensor 168b, the sewage suction pump 166e can stop operating.

[0510] As another example, when the water level in the sewage tank 166 reaches the height of the first sensor 168a and the height of the second sensor 168b, the sewage discharge pump 167b can operate until it detects that the water level in the sewage tank 166 has dropped below the first sensor 168a.

[0511] This configuration prevents sewage in the sewage tank 166 from flowing back into the sewage suction pump 166e or the sewage inlet 166c.

[0512] The sewage discharge pump 167b can create positive pressure in the sewage tank 166 to discharge liquid to the outside. At this time, the water level in the sewage tank 166 can drop. At this time, the sewage inlet 166c can be closed by the check valve 166d.

[0513] Additionally, the cloth washing section 160 may include an additional check valve (not shown). This check valve prevents fluid inside the drain pipe 25 from flowing back into the wastewater discharge path 167. The check valve may be located at the other end of the wastewater discharge path 167 connected to the drain pipe 25.

[0514] Cloth Drying Section

[0515] Reference Figures 34 to 38 In one embodiment of the present invention, the robot vacuum cleaner base station 100 may include a cloth drying unit 170. At this time, the cloth drying unit 170 can dry the cloth 242 of the robot vacuum cleaner 200 that has been washed by the cloth washing unit 160 or the cloth 242 that is wet after completing a wet cleaning operation.

[0516] The cloth drying unit 170 may include an external gas supply module 171 and an air exhaust unit 172.

[0517] The external gas supply module 171 can heat the air outside the enclosure 110 and supply it to the containing space S. The external gas supply module 171 may include an external gas supply flow path 171a, an external gas inlet 171b, an external gas outlet 171c, a heater 171d, and a blower fan (not shown).

[0518] The external gas supply module 171 has an external gas supply flow path 171a. The external gas supply flow path 171a allows external air to flow to the external gas discharge section 171c.

[0519] The external gas supply path 171a can connect the external space of the enclosure 110 with the containment space. One side of the external gas supply path 171a can be connected to the external space through the external gas inlet 171b, and the other side of the external gas supply path 171a can be connected to the containment space S through the external gas outlet 171c.

[0520] An external gas inlet 171b may be formed on the rear side of the enclosure 110. Multiple external gas inlets 171b may be formed on the rear side of the enclosure 110. Air from outside the enclosure 110 can flow into the external gas supply path 171a through the external gas inlets 171b. Therefore, air from outside the enclosure 110 can flow into the interior of the enclosure 110.

[0521] At least a portion of the external gas discharge section 171c may be disposed on the upper side of the washing plate 122. The external gas discharge section 171c may open in a direction opposite to the washing plate 122. A pair of external gas discharge sections 171c may be provided in a downward-opening state.

[0522] The external gas discharge section 171c can discharge air that has passed through the external gas supply flow path 171a. The external gas discharge section 171c can also discharge air heated by the heater 171d. For example, the external gas discharge section 171c can be formed with an external gas discharge port.

[0523] On the other hand, in this embodiment, the left-right diameter of the external gas discharge section 171c can become narrower towards the front. That is, in this embodiment, the width of the rear end of the left-right diameter of the external gas discharge section 171c can be greater than the width of the front end. This ensures that even when the disc-shaped cloth 242 rotates during the drying process, the cloth 242 can be dried evenly.

[0524] On the other hand, the external gas discharge section 171c may have a grid to guide the discharge direction of the air. This prevents the heated air from being concentrated and discharged at a specific location.

[0525] With the cloth 242 placed on the washing plate 122, the external gas discharge section 171c can open to the upper side of the cloth 242. Therefore, the external gas discharge section 171c can be arranged adjacent to the cloth 242 and open downward, allowing the air discharged from the external gas discharge section 171c to flow towards the cloth 242.

[0526] In particular, the external gas discharge section 171c of this embodiment can be configured to tilt downwards as it gets closer to the front of the robot vacuum base station 100. Therefore, the end of the external gas discharge section 171c that discharges air can be formed at a predetermined angle relative to the ground. This angle can be 90 degrees or less. Thus, the external gas discharge section 171c can discharge air in a direction intersecting the direction where the flow guide surface 122c is formed.

[0527] An air supply fan (not shown) can be configured on the external gas supply path 171a to blow air into the containment space S. If the air supply fan (not shown) is driven, the air flowing in through the external gas inlet 171b can be heated by the heater 171d and then discharged into the containment space S through the external gas outlet 171c.

[0528] The heater 171d can be configured on the external gas supply flow path 171a to heat the air flowing in the external gas supply flow path 171a. The heater 171d can also heat the air discharged through the external gas discharge section 171c.

[0529] The heater 171d may include a heater housing and a heating element. The heater housing may be positioned on the external gas supply path 171a, and an internal space may be provided to accommodate the heating element. Furthermore, the heating element can heat the air flowing into the heater housing. Therefore, the air heated by the heating element can be discharged into the accommodating space S through the external gas outlet 171c, drying the damp cloth 242.

[0530] Air heated by hot gas emitted from the external gas supply module 171 can be discharged through the air exhaust section 172.

[0531] At least a portion of the air exhaust section 172 may be disposed in the upper part of the accommodating space S.

[0532] The air heated by the hot air emitted from the external gas supply module 171 can supply heat to the mop 242 of the robotic vacuum cleaner 200. As a result, residual moisture absorbed by the mop 242 can absorb heat from the air and vaporize. This vaporized moisture can then flow within the containment space S. Therefore, the air within the containment space S may include vaporized moisture, and the humidity within the containment space S may increase (hereinafter, the air containing vaporized moisture within the containment space S can be referred to as "wet steam").

[0533] Specifically, at least a portion of the air exhaust section 172 may be disposed on the upper cover 113, which may cover the upper part of the accommodating space S.

[0534] The air heated by the hot air emitted from the external gas supply module 171 can vaporize the moisture in the rag 242, causing the humidity to rise. Therefore, if the robot vacuum base station 100 is located under the kitchen cabinet 2, the wet steam may adversely affect various components of the kitchen cabinet 2, such as the kickboard 26.

[0535] In this embodiment, since the upper cover 113 covers the upper part of the accommodating space S and the door 126 covers the front of the accommodating space S, the upper cover 113 and the door 126 together prevent the humid steam in the accommodating space S from leaking to the outside, thereby preventing the kitchen cabinet 2 from coming into contact with humid steam.

[0536] The air exhaust section 172 may include an air intake 172a, an air exhaust duct 172b, and an exhaust fan 172c.

[0537] Air intake 172a can communicate with the containment space S. Air intake 172a can be disposed on the upper side of the containment space S. Wet vapor in the containment space S can be discharged through air intake 172a.

[0538] The air intake 172a can be positioned at a higher point from the ground than the robot vacuum 200 itself, while the robot vacuum 200 is mounted on the mounting section 120. This improves the efficiency of drawing in the rising convection steam generated during the drying of the mop.

[0539] As an example, an air intake 172a can be formed on the upper cover 113. In this case, the upper cover 113 can be formed by stacking two or more plates, wherein the lowermost plate can have an air intake 172a, and a flow path communicating with the air intake 172a is formed between the plates to form an air exhaust pipe 172b.

[0540] As another example, the air intake 172a can be formed on the circular or quadrilateral tubular air exhaust pipe 172b, which can be attached to the upper side cover 113.

[0541] With this configuration, when the upper cover 113 is separated, the air exhaust pipe 172b can be separated together with the upper cover 113. This has the advantage that when the upper part of the robot vacuum base station 100 needs to be opened for reasons such as repair, the operator can remove the air exhaust pipe 172b by simply lifting the upper cover 113.

[0542] The air intake 172a can be formed in the air exhaust duct 172b as a hole. For example, the air intake 172a can be formed as a plurality of slits arranged side by side in the air exhaust duct 172b. Alternatively, the air intake 172a can be formed in the air exhaust duct 172b as an elongated hole.

[0543] On the other hand, a plurality of air intake ports 172a may be arranged at the same distance from the front end of the cover 110. As an example, a pair of air intake ports 172a may be arranged at the same distance from the front end of the cover 110. That is, the air intake ports 172a may include a first intake port and a second intake port. In this case, the first intake port may be arranged at the upper left front end of the accommodating space S, and the second intake port may be arranged separately from the first intake port, and may be arranged at the upper right front end of the accommodating space S.

[0544] The distance from the external gas outlet 171c to the air inlet 172a can be greater than the distance from the external gas outlet 171c to the cloth 242. This is to prevent the heated air discharged from the external gas outlet 171c from being insufficiently supplied to the cloth 242 and instead being directly sucked into the air inlet 172a, thus wasting energy.

[0545] Furthermore, the air intake 172a can be positioned closer to the door 131 than the external gas exhaust 171c. Since the air intake 172a is located at the upper front of the accommodating space S, the space for the hot air exhausted from the external gas exhaust 171c to flow is widened, thereby improving the drying efficiency of the mop 242. Therefore, after the hot air exhausted through the external gas exhaust 171c flows forward and dries the mop 242 of the robot vacuum 200, it can be discharged into the air intake 172a.

[0546] Additionally, the air intake 172a can be positioned above the path along which the robotic vacuum cleaner 200 moves within the housing 110. This prevents condensation from forming on the inner walls of the housing 110.

[0547] As an example, at least a portion of the air intake 172a can be positioned vertically above the location where the sweeping robot 200 has the greatest width in the left-right direction when it is positioned in the mounting section 120. That is, at least a portion of the air intake 172a can be positioned above the location where the gap between the sweeping robot 200 and the pair of inner walls 124 is smallest. In this case, at least a portion of the air intake 172a can be positioned closer to the front than the wash plate 122.

[0548] This prevents steam generated during the drying process of the mop 242 from flowing towards the front of the robot vacuum base station 100, and prevents the sensors located in front of the robot vacuum 200 from malfunctioning due to moisture penetration.

[0549] The air exhaust duct 172b can connect the air intake 172a and the exhaust fan 172c to the drain pipe 25 of the kitchen cabinet 2. The air exhaust duct 172b can direct the wet steam discharged through the air intake 172a to the drain pipe 25.

[0550] One side of the air exhaust duct 172b can be connected to the exhaust fan 172c, while the other side can branch into multiple branches. In this way, even when using a single exhaust fan 172c, humid steam can be drawn in from multiple locations, thus achieving the effect of stably expelling humid steam.

[0551] The interior of the air exhaust pipe 172b can form an air exhaust flow path that communicates with the air intake 172a.

[0552] An air exhaust path can represent a flow path for air to flow in through an air intake 172a. For example, the air exhaust path may be formed by the internal space of an air exhaust duct 172b, the internal space of the casing of an exhaust fan 172c, and the internal space of a check valve 172d. One side of the air exhaust path may be connected to the air intake 172a, and the other side may be connected to the air exhaust outlet 172e.

[0553] The exhaust fan 172c can induce airflow from the air intake 172a toward the drain pipe 25. The exhaust fan 172c can induce airflow so that the wet vapor in the containing space S is drawn into the air intake 172a and discharged to the outside through the air exhaust pipe 172b.

[0554] The exhaust fan 172c may include an exhaust fan housing, a fan motor, and an impeller. The interior of the exhaust fan housing may have a flow path that communicates with the air exhaust duct 172b. If the exhaust fan motor operates and causes the exhaust fan impeller to rotate, the air in the accommodating space S or the housing 110 may flow into the air exhaust duct 172b and be discharged through the interior of the exhaust fan housing to the air exhaust outlet 172e.

[0555] On the other hand, in this embodiment, the exhaust fan 172c can be combined with the external gas supply module 171. Specifically, the exhaust fan housing of the exhaust fan 172c can be combined with the external gas supply module 171 to form an assembly. In this way, the space occupied by the external gas supply module 171 and the air exhaust section 172 can be minimized.

[0556] The exhaust fan 172c can be configured on the left or right side of the external gas supply module 171. Specifically, the exhaust fan 172c can be configured between the dust collection motor 145 and the external gas supply module 171. In this way, components can be arranged in a limited space, and space can be ensured for the configuration of the flow path for exhaust steam.

[0557] If the exhaust fan 172c is driven, air in the accommodating space S can flow into the air intake 172a. The air flowing into the air intake 172a can be discharged into the drain pipe 25.

[0558] The cloth drying unit 170 may include a check valve 172d to prevent backflow of fluid from inside the drain pipe 25 into the air discharge pipe 172b. The check valve 172d may be positioned downstream of the exhaust fan 172c. The check valve 172d may communicate with the internal space of the exhaust fan 172c. That is, based on the airflow direction, the check valve 172d may be positioned downstream of the exhaust fan 172c. An air outlet 172e may be formed at the rear end of the check valve 172d. The check valve prevents backflow of fluid from inside the drain pipe 25 into the air discharge unit 172.

[0559] At this point, the lower end of the air outlet 172e can be configured in a direction perpendicular to the ground. Specifically, the air outlet 172e can be formed in an air discharge pipe configured in a direction perpendicular to the ground, and the aforementioned air discharge pipe can be connected to a check valve. With this configuration, the backflow of fluid discharged from the air outlet 172e is prevented by utilizing the upward convection property of hot and humid air.

[0560] The air exhaust 172 can be connected downstream of the drain pipe 25, based on the trap 25a of the drain pipe 25. Specifically, the air exhaust outlet 172e can be connected to the drain pipe 25 via a flow path member. For example, the flow path member can be a flexible hose. This is because, if the air exhaust 172 is connected upstream of the drain pipe 25, based on the trap 25a of the drain pipe 25, water accumulated in the trap 25a may prevent hot air exhausted through the air exhaust 172 from passing through the drain pipe 25. Additionally, this is to prevent foul odors generated in the air exhausted from the air exhaust 172 from flowing back along the drain pipe 25 and spreading into the kitchen.

[0561] The wet steam that is discharged into the air intake 172a and passed through the exhaust fan 172c can be discharged to the outside of the cover 110 via the air outlet 172e along the flow path member.

[0562] At this time, the flow path component can pass through either side of the outer wall and connect to the drain pipe 25. With this configuration, the connection direction of the flow path component can be selected according to the installation environment of the robotic vacuum cleaner base station 100 according to the present invention, thereby having the advantage of easy installation and management.

[0563] drawer

[0564] While placing the robot vacuum's charging dock under a kitchen cabinet can provide a decorative effect by minimizing external exposure, it can also be difficult for the user to remove and repair the robot if it malfunctions while inside the cabinet or if the charging dock itself fails. To address this issue, the present invention adds a drawer 190 to the robot vacuum base station 100.

[0565] In this regard, Figure 39 A diagram is shown illustrating the state of the drawer extending from the base station of the robotic vacuum cleaner according to an embodiment of the present invention.

[0566] Reference Figure 39 The drawer 190 of the robot vacuum cleaner base station 100 according to an embodiment of the present invention is described below.

[0567] 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.

[0568] The drawer 190 can move relative to the cover 110. For example, the cover 110 can be fixedly attached to the kitchen cabinet 2, and the drawer 190 can be extended forward from the cover 110.

[0569] At this time, drawer 190 can be extended with the internal storage unit 120 installed. With the above configuration, if drawer 190 is extended, the storage unit 120 and / or the robot vacuum cleaner 200 can be extended from the kitchen cabinet 2 to the outside.

[0570] At this time, with the door 131 closing the entrance 127, if the drawer 190 is pulled out from the cover 110, the upper cover 113 can be exposed to the outside. At this time, if the upper cover 113 is separated, the robot vacuum cleaner 200 can be exposed to the outside.

[0571] Therefore, according to this embodiment, in the event of maintenance or warranty of the robot vacuum base station 100, such as repair or cleaning, the user can easily pull out the installation part 120 and / or the robot vacuum 200 through the drawer 190, thereby exposing the internal components of the robot vacuum base station 100 or the robot vacuum 200.

[0572] On the other hand, in one embodiment of the present invention, the drawer 190 can be extended with a dust collection section 140 provided inside. In this case, the extension direction of the drawer 190 can be parallel to the extension direction of the dust bag drawer 144.

[0573] In another embodiment of the present invention, the drawer 190 can be extended together with the dishcloth washing unit 160. Specifically, the drawer 190 can be extended together with the detergent container 163. In this case, the extension direction of the drawer 190 can be parallel to the extension direction of the detergent container 163.

[0574] With the above configuration, the robot vacuum cleaner base station 100 of an embodiment of the present invention can be configured such that the drawer 190, the dust bag drawer 144, and the detergent bucket 163 are all parallel in their outward directions.

[0575] Therefore, it has the effect that users can easily identify the lead-out direction of the constituent elements of the robot vacuum cleaner base station 100 of the present invention, and can easily lead out for repair and maintenance of warranty.

[0576] Drawer 190 may include drawer sidewall 191, assembly 192, and drawer slide 193.

[0577] The drawer sidewalls 191 are configured to move relative to the outer wall of the cover 110. For example, a pair of drawer sidewalls 191 may be configured such that one outer wall of the cover 110 faces the other.

[0578] At this time, the pair of drawer sidewalls 191 can be positioned closer to the inside of the robot vacuum base station 100 than one pair of outer walls of the cover 110. That is, the pair of drawer sidewalls 191 can be positioned closer to the mounting section 120 than one pair of outer walls of the cover 110.

[0579] On the other hand, a dust collection section 140 and / or a cloth washing section 160 may be provided between the drawer side wall 191 and the placement section 120.

[0580] With the above configuration, the dust collection unit 140 and the cloth washing unit 160 can be arranged using minimal horizontal space.

[0581] Drawer slides 193 can be configured on the drawer sidewall 191 to guide the movement of the drawer sidewall 191. Drawer slides 193 can be fixedly attached to the drawer sidewall 191 or integrally formed with the drawer sidewall 191, engaging with the slides provided on the outer wall 111 of the cover 110 and guiding the movement path of the drawer sidewall 191. On the other hand, while the present invention describes the case where slides are provided on the drawer 190 and the cover 110, it is not necessarily limited to the form of the slides; it can include alternatives such as rollers, guide grooves, or guide ribs.

[0582] Control Structure

[0583] Figure 40 A block diagram illustrating the control configuration of a vacuum cleaner base station for explaining an embodiment of the present invention is shown.

[0584] Reference Figure 40 The control configuration of the sweeping robot base station 100 of the present invention is described below.

[0585] The vacuum cleaner base station 100 of this embodiment of the invention also includes a control unit 300 comprising a control placement unit 120, a dust collection motor 145, a cloth washing unit 160, and a cloth drying unit 170.

[0586] The control unit 300 may consist of a printed circuit board and a plurality of components mounted on the printed circuit board.

[0587] The control unit 300 can receive signals from the entry sensor 135 and control the door drive unit 134.

[0588] The control unit 300 can detect the approach of the robotic vacuum cleaner 200 and control the door drive unit 134 to rotate the door 131. Specifically, the control unit 300 can detect whether the robotic vacuum cleaner 200 has entered via the entry sensor 135. If the distance between the robotic vacuum cleaner 200 and the door 131 is less than a preset distance, the door 131 can be rotated to open the entrance 127. Alternatively, if the robotic vacuum cleaner 200 is attached to the mounting unit 120, the control unit 300 can rotate the door 131 to close the entrance 127.

[0589] If power is supplied to the battery of the robot vacuum cleaner 200 from the power supply terminal 123b, the control unit 300 can determine that the robot vacuum cleaner 200 is attached to the mounting unit 120.

[0590] The control unit 300 can drive the dust collection motor 145 to suck up dust from inside the dust bin 220 of the robot vacuum cleaner 200.

[0591] On the other hand, the robotic vacuum cleaner base station 100 in this embodiment of the invention may include a memory (not shown). The memory may include various data for driving and operating the robotic vacuum cleaner base station 100.

[0592] On the other hand, the robotic vacuum cleaner base station 100 of this embodiment may include a communication unit (not shown). The communication unit may support wireless communication with other devices located outside the robotic vacuum cleaner base station 100, including the robotic vacuum cleaner 200 or a terminal (not shown). As a wireless communication module for supporting wireless communication, a short-range communication module or a long-range communication module may be provided.

[0593] Near-field communication can be, for example, Bluetooth communication, NFC (Near Field Communication) communication, etc.

[0594] Long-distance communication can include, for example, Wireless LAN (WLAN), DLNA (Digital Living Network Alliance), Wireless Broadband (Wibro), World Interoperability for Microwave Access (WiMAX), GSM (Global System for Mobile communication), CDMA (Code Division Multi Access), CDMA2000 (Code Division Multi Access 2000), EV-DO (Enhanced Voice-Data Optimized or Enhanced Voice-Data Only), WCDMA (Wideband CDMA), HSDPA (High Speed ​​Downlink Packet Access), HSUPA (High Speed ​​Uplink Packet Access), IEEE 802.16, Long Term Evolution (LTE), and LTE-A (Long Term Evolution). Evolution-Advanced (EAD), Wireless Mobile Broadband Service (WMBS), Bluetooth Low Energy (BLE), Zigbee, Radio Frequency (RF), LoRa (Long Range), etc.

[0595] The control unit 300 can control the cloth washing unit 160.

[0596] Specifically, the control unit 300 can control the detergent pump 163b. The control unit 300 can operate the detergent pump 163b to dispense detergent stored in the detergent tank 163 into the dishcloth 242.

[0597] Additionally, the control unit 300 can control the regulator 161. The control unit 300 can operate the regulator 161 to adjust the amount of clean water dispensed into the wiping cloth 242.
