Description

Technical Field

[0001] This utility model relates to a base station for a robotic vacuum cleaner, and more specifically, to a built-in base station for a robotic vacuum cleaner that, when combined with a robotic vacuum cleaner, can collect dust from the vacuum cleaner's dustbin, wash the 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] On the other hand, Chinese utility model patent CN219183596U discloses an automatic washing vacuum cleaner base station that can freely add detergent, but does not disclose detailed information about the hygiene of the dust collection section.

[0013] In addition, Chinese utility model patent CN217827730U discloses the drying function of a robot vacuum cleaner's cleaning system through a drying device. However, it does not disclose the hygiene management of the dust bag.

[0014] However, if unsterilized foreign objects accumulate in the dust collection section for an extended period, pests and microorganisms may breed. In particular, mites such as grain mites are microorganisms that parasitize insufficiently dried grains. When grains are captured in the dust collection section in a hot and humid environment, they may easily multiply and may escape to the outside by moving along the flow path of the vacuum cleaner base station. Utility Model Content

[0015] Problems to be solved by the utility model

[0016] This utility model is proposed to improve the problems existing in the above-mentioned existing robot vacuum cleaner base stations. Its purpose is to provide a robot vacuum cleaner base station that does not require 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 station that can automatically wash the robot vacuum's mop when combined with a robot vacuum.

[0020] In addition, the purpose is to provide a robot vacuum cleaner base station that can automatically dry the mop cloth after washing it.

[0021] In addition, the purpose is to provide a robot vacuum cleaner base station that can be brought out for cleaning and repair as needed.

[0022] In addition, its purpose is to provide a robot vacuum station that can prevent dust from flying outwards when the robot vacuum is collecting dust.

[0023] In addition, the purpose is to provide a robot vacuum cleaner base station that can prevent wastewater from leaking to the outside when washing the robot vacuum cleaner's mop.

[0024] In addition, the purpose is to provide a robot vacuum base station that sterilizes the interior of the dust collection unit cover and dust bag in order to keep the dust collected by the robot vacuum hygienic.

[0025] In addition, the purpose is to provide a robot vacuum base station that uses a heater, a circulating fan, and a flow path switching valve in the cloth drying section to sterilize the dust collection cover and dust bag without additional modules.

[0026] Technical solutions to the problem

[0028] On the other hand, the dust collection unit sterilization module may include: a circulating fan that causes air to flow into the interior space of the dust collection unit cover; and a heater that heats the air flowing using the circulating fan.

[0029] Additionally, the dust collection unit cover may include: a hot air inlet for air flowing into the dust collection unit sterilization module; and a hot air outlet for discharging air flowing in from the hot air inlet.

[0030] On the other hand, the dust collection unit sterilization module can be configured on the rear side of the dust collection unit cover.

[0031] It may include a dust collection motor that sucks up dust from the dust bin of the sweeping robot, and the dust collection sterilization module may be configured between the dust collection motor and the dust collection cover.

[0032] The system may include a cloth drying section disposed within the housing to dry the cloth of the robotic vacuum cleaner. The cloth drying section may include: a circulating fan to circulate air; and a heater to heat the air circulated by the circulating fan. The dust collection housing may include a hot air inlet for the air flowing through the cloth drying section to enter. The cloth drying section and the dust collection housing may be connected by a first circulation path.

[0033] The cloth drying unit may include: an external gas supply path that discharges heated air into the accommodating space; and a first flow path switching valve that selectively opens and closes the external gas supply path and the first circulation path.

[0034] On the other hand, the sweeping robot base station of this utility model may include a sensor for measuring the moisture content of the mop, and the first flow path switching valve may open the first circulation flow path when the moisture content measured by the sensor is below a preset reference value.

[0035] On the other hand, the dust collection unit cover may include a temperature sensor that measures the internal temperature. If the temperature measured by the temperature sensor is above a preset reference value, the first flow path switching valve may close the first circulation flow path.

[0036] In addition, the dust collection unit cover may include a temperature sensor for measuring the internal temperature. If the temperature measured by the temperature sensor is above a preset reference value, the operation of the heater can be stopped.

[0037] Additionally, the dust collection unit cover may include: a hot air outlet for discharging air flowing in from the hot air inlet; the robot vacuum base station may include: an air exhaust section, including an air exhaust flow path for discharging air from inside the cover to the outside; the air exhaust section may include: a second circulation flow path for causing air flowing into the dust collection unit cover to flow to the air exhaust section; and a second flow path switching valve for opening and closing the second circulation flow path.

[0038] On the other hand, the robot vacuum cleaner base station of this utility model may include a sensor for measuring the moisture content of the mop, and the second flow path switching valve may open the second circulation flow path when the moisture content measured by the sensor is below a preset reference value.

[0039] In addition, the dust collection unit cover may include a temperature sensor for measuring the internal temperature. If the temperature measured by the temperature sensor is above a preset reference value, the second flow path switching valve may close the second circulation flow path.

[0040] On the other hand, the dust collection unit sterilization module may include a light source for irradiating sterilization light, and the light source may be disposed on the upper rear side inside the dust collection unit cover.

[0041] It may include: a dust bag, housed inside the dust collection unit cover, for collecting dust flowing in from the robot vacuum cleaner; and a transmission panel, disposed on the upper side of the dust bag, through which the sterilization light is transmitted.

[0042] Alternatively, the light source can be a UV-C LED.

[0043] On the other hand, the control method of the sweeping robot base station of this utility model may include: a cloth drying step, drying the cloth of the sweeping robot and measuring the moisture content of the cloth by a sensor; a flow path conversion step, in which the first flow path conversion valve is operated to change the air flow path when the moisture content measured in the cloth drying step is lower than a preset reference value; and a dust collection unit sterilization step, in which hot air is expelled into the dust collection unit cover after the flow path conversion step to sterilize the interior.

[0044] On the other hand, the dust collection sterilization step can activate the first flow path switching valve or interrupt the operation of the heater after a preset time or when the temperature sensor measurement value is above the baseline value.

[0045] Utility Model Effect

[0046] As described above, in the robot vacuum cleaner base station of this utility model, the modules for charging the robot vacuum cleaner, collecting dust, and washing the mop are arranged in a direction horizontal to the robot vacuum cleaner, thereby effectively utilizing the space under the kitchen cabinet.

[0047] 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.

[0048] In addition, by centrally arranging the washing water supply unit, washing plate, washing tank, sewage discharge path, external gas supply module and power supply module at the rear of the cleaning robot's cloth, it is possible to achieve the washing and drying effect of the cloth within a limited space.

[0049] 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.

[0050] In addition, since the dust is automatically collected from the dustbin of the robot vacuum after being integrated, the user only needs to remove the dust bag at predetermined intervals, thus reducing the burden on the user.

[0051] In addition, since the robot vacuum cleaner can automatically wash its mop cloth when combined with it, it reduces the hassle of separating the mop cloth and washing it separately.

[0052] In addition, since detergent can be added as needed, it can improve the washing effect of the cloth.

[0053] In addition, since the kitchen's water supply and drainage pipes are used to wash the dishcloths, it reduces the hassle for users to separately fill or drain water.

[0054] In addition, since the cleaning cloth of the robot vacuum cleaner can be automatically dried and discharged by supplying hot air to the cloth after washing, it has the effect of preventing the generation of bad odors.

[0055] In addition, during the drying process of the cloth, the dried air is discharged downstream of the water trap, which has the effect of preventing the backflow of foul odors.

[0056] In addition, since the door of the robot vacuum station is closed after the robot vacuum enters the station, it has the effect of preventing dust from flying outwards while collecting dust in the dust bin.

[0057] In addition, sterilizing the dust collection unit cover and dust bag can prevent bacterial growth and the generation of foul odors. Attached Figure Description

[0100] Furthermore, the following embodiments are provided to provide a more complete explanation to those skilled in the art, and the shapes and dimensions of the elements in the accompanying drawings may be exaggerated for clarity.

[0101] Kitchen cabinets and vacuum cleaner system

[0102] 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.

[0103] The vacuum cleaner system 1 of this utility model embodiment can be installed on the lower side of the kitchen cabinet 2. Specifically, the kitchen cabinet 2 can be configured in the kitchen to store bowls, plates, cups, etc., and can provide space for cooking food or washing dishes.

[0104] In addition, kitchen cabinet 2 can be equipped with a countertop (workbench) that can function as a dishwashing station, cooking station, or work station.

[0105] 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.

[0106] 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.

[0107] 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 source supplying fluid to the structure, and the drain pipe may represent a flow path discharging fluid discharged from the structure into a sewer.

[0108] 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.

[0109] 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.

[0110] 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.

[0111] As described above, the vacuum cleaner system 1 of this utility model embodiment is installed in the space between the kitchen floor and the lower side panel 23 (hereinafter referred to as the installation space).

[0112] For example, the installation space can be less than 200mm in height, and typically can be less than 160mm in height.

[0113] Therefore, according to this utility model, 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.

[0114] In addition, compared with the case of setting up a charging dock for a robot vacuum cleaner in a specific space in the living room, bedroom or kitchen, this utility model 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.

[0115] 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.

[0116] The vacuum cleaner system 1 of this utility model embodiment can use the drain pipe 25 as described above to wash and dry the mop 242 of the sweeping robot 200.

[0117] 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.

[0118] The following describes the specific structure of vacuum cleaner system 1.

[0119] Vacuum Cleaner System

[0120] on the other hand, Figures 3 to 5 A diagram is shown illustrating a vacuum cleaner system according to an embodiment of the present invention.

[0121] The vacuum cleaner system 1 of this utility model embodiment may include a robot vacuum base station 100 and a robot vacuum 200.

[0122] 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.

[0123] robot vacuum cleaner

[0124] on the other hand, Figures 6 to 9 A diagram is disclosed to illustrate a sweeping robot system according to an embodiment of the present invention.

[0125] Reference Figures 6 to 9 The structure of the 200 robotic vacuum cleaner is described below.

[0126] 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.

[0127] The sweeping robot 200 of this embodiment is configured to sweep the floor while moving on the floor after being placed on it. Therefore, the following description defines and explains the vertical direction based on the state of the sweeping robot 200 placed on the floor.

[0128] 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.

[0129] The “lowest part” of each component described in this embodiment of the present invention may be the part located at the lowest point in each component when the sweeping robot 200 of this embodiment of the present invention is placed on the ground and used, or it may be the part closest to the ground.

[0130] The sweeping robot 200 of this utility model embodiment includes a main body 210, a dust bin 220, a water bin 230, a rotating sweeping part 240, an agitator 250, wheels 260, auxiliary wheels 270, and a charging terminal 280.

[0131] 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.

[0132] 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.

[0133] In this embodiment of the invention, the main body 210 can be configured such that its width (or diameter) in the horizontal direction (parallel to X and Y) is greater than its height in the vertical direction (parallel to Z). Such a main body 210 helps to create a stable structure for the robotic vacuum cleaner 200 and provides a structure that facilitates obstacle avoidance when the robotic vacuum cleaner 200 moves (drives).

[0134] 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.

[0135] 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.

[0136] 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.

[0137] The lower body may have an intake section 211 for air to flow in and a hole for accommodating a pair of wheels 260.

[0138] 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.

[0139] 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.

[0140] 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.

[0141] 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.

[0142] 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.

[0143] The sweeping robot 200 of this invention may include a bumper strip. The bumper strip is attached along the edge of the main body 210 and is configured to move relative to the main body 210.

[0144] 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.

[0145] The dust bin 220 can be configured to draw in external dust and air and store the dust.

[0146] 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.

[0147] 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.

[0148] On the other hand, the dust bin 220 of this invention can form 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 using the robotic vacuum cleaner base station 100 to collect dust, the dust inside the dust bin 220 can be removed.

[0149] On the other hand, the dust bin 220 of this embodiment of the invention may have a dust outlet 221 that communicates with the dust discharge path. As one example, the dust outlet 221 may be formed on the rear side of the outer side (or outer peripheral surface) of the main body 210. As another example, the dust outlet 221 may be formed on the outer side of the dust bin 220.

[0150] 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.

[0151] 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.

[0152] 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.

[0153] 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.

[0154] 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.

[0155] 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.

[0156] 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.

[0157] 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.

[0158] 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.

[0159] The rotating cleaning unit 240 includes a rotating plate 241 and a cleaning cloth 242.

[0160] 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.

[0161] 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.

[0162] 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 ground B or inclined to it. The rotating plate 241 can be configured as a circular plate, with its bottom surface forming a roughly circular shape, and the rotating plate 241 can be configured as a whole with rotational symmetry.

[0163] A pair of rotating plates 241 can be arranged to be symmetrical to each other.

[0164] The rag 242 can be attached to the underside of the rotating plate 241 so as to be opposite the ground B.

[0165] 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 B or can be inclined to the ground B.

[0166] 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.

[0167] 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.

[0168] 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.

[0169] 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.

[0170] 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.

[0171] Wheel 260 can be installed on the main body 210 and can roll on the ground.

[0172] 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.

[0173] 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.

[0174] 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.

[0175] 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.

[0176] 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.

[0177] 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.

[0178] 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).

[0179] In addition, the battery can power the sensor unit (not shown) and the control unit (not shown).

[0180] 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.

[0181] Robot vacuum cleaner base station

[0182] Figure 10 A perspective view of a robot vacuum cleaner base station illustrating an embodiment of the present invention is shown. Figure 11 It shows Figure 10 Top view.

[0183] Reference Figure 10 and Figure 11 The following is a description of the robot vacuum cleaner base station 100 of this utility model.

[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 form a space that can accommodate the placement section 120, the dust collection path (not shown), the dust collection section 140, the dust collection motor 145, the cloth washing section 160, the cloth drying section 170, and the circulation path.

[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 one example, a pair of outer walls 111 can be arranged at predetermined intervals on the underside of the kitchen cabinet 2. As another example, the cover 110 may also include a bottom surface facing the kitchen floor, and a pair of outer walls can be connected through the bottom surface.

[0191] As another example, the cover 110 may also include a bottom surface facing the kitchen floor and an upper surface 113 facing the lower side panel 23 of the kitchen cabinet 2. The upper and lower ends of a pair of outer walls 111 may be connected to each other by the bottom surface and the upper surface 113. Therefore, in the event of foreign objects falling from the kitchen cabinet 2 to the lower side, it is possible to prevent the components of the robot vacuum cleaner 200 and the robot vacuum cleaner base station 100 from being contaminated. As yet another example, the cover 110 may also include the bottom surface, the upper surface 113, and the rear surface 111b facing the wall of the building.

[0192] With the above configuration, the components of the robot vacuum cleaner base station 100 can be accommodated inside the cover 110 (between one pair of outer walls).

[0193] 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.

[0194] 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.

[0195] 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.

[0196] 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.

[0197] 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.

[0198] 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, except for the robot vacuum base station 100, is edged by the baseboard, only the front of the cover 110 can be exposed to the outside.

[0199] This minimizes the exposure of the robot vacuum base station 100 and the robot vacuum 200 to the outside.

[0200] With the above-described configuration, the sweeping robot base station 100 of this utility model has the effect of providing aesthetic appeal to users in terms of decoration.

[0201] On the other hand, although not shown in the figure, 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, at least one of the outer wall 111 and the upper side 112 of the cover 110 may have a space for the aforementioned hose to pass through.

[0202] Joint

[0203] like Figure 11 As shown, the robot vacuum cleaner base station 100 may include a mounting unit 120.

[0204] 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.

[0205] The mounting section 120 can be installed inside the cover 110.

[0206] In this case, according to the embodiment, the placement part 120 can be configured to be drawn out from the cover 110 via the drawer 190.

[0207] With the above configuration, the user can easily access and manage the installation section 120 when it needs to be washed or repaired, or when some parts need to be replaced.

[0208] The installation unit 120 can be configured with an entrance 127 for the robotic vacuum cleaner 200 to enter. The entrance 127 can be defined as the space formed in front of the robotic vacuum cleaner base station 100.

[0209] The entrance / exit 127 can be sized to allow the robot vacuum cleaner 200 to pass through. That is, the height of the entrance / exit 127 can be greater than the height of the robot 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), and the upper end of the entrance / exit can be the same as the lower side of the lower side panel 23 of the kitchen cabinet 2 or the upper end of the cover 110.

[0210] Furthermore, the lateral width of the entrance / exit 127 is greater than the maximum width of the robotic vacuum cleaner 200. In this case, at least one of the dust collection section 140 and the mop washing section 160 can be arranged on the left and right sides of the entrance / exit 127. Therefore, the left and right ends of the entrance / exit 127 can form boundaries with the dust collection section 140 and the mop washing section 160. When neither the dust collection section 140 nor the mop washing section 160 is present, the outer wall surface of the cover 110 can also form the boundary.

[0211] At this time, the entrance / exit 127 can be opened and closed by the door 126. The door 126 can be configured at the upper or lower end of the entrance / exit 127, and can be provided with a rotation axis in a direction parallel to the base 121. The door 126 can be hinged to the cover 110. Alternatively, the door 126 can be hinged to the inner wall 124 of the mounting part 120.

[0212] Door 126 can be rotated using door drive unit 126a. As an example, door drive unit 126a can be a motor.

[0213] For example, the door 126 can be formed as a rectangular flat plate, with a hinge portion 126b at the top, and a door drive portion 126a connected to one axial end of the hinge portion 126b. In this case, the hinge portion 126b of the door 126 can be directly connected to the shaft of the door drive portion 126a, or it can be connected to transmit power through at least one or more gears.

[0214] Door 126 can remain closed at the entrance / exit 127 while the robotic vacuum cleaner 200 is housed in the mounting section 120. Alternatively, when the robotic vacuum cleaner 200 begins to move from the mounting section 120, door 126 can rotate to open the entrance / exit 127. Furthermore, door 126 can rotate to close the entrance / exit 127 after the robotic vacuum cleaner 200 has passed through it. Additionally, door 126 can rotate to open the entrance / exit 127 when the robotic vacuum cleaner 200 approaches the outside of the vacuum cleaner base station 100.

[0215] The placement part 120 may include a receiving space S, a base 121, a connecting wall 123, and an inner wall 124.

[0216] 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.

[0217] The base 121 can be configured to allow the robot vacuum base station 100 to contact the bottom surface, and can support the robot vacuum 200 when it is attached to the robot vacuum base station 100. The base 121 may include a base body 121a, an inclined part 121b, a wheel engagement part 121c, an agitator receiving part 121d, and a cleaning tank 128.

[0218] 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.

[0219] The base body 121a can be shaped such that its width (or diameter) in the horizontal direction (parallel to X and Y) is greater than its height in the vertical direction (parallel to Z). This structure allows the robotic vacuum cleaner base station 100 to be stably supported on the ground.

[0220] A circulation path can be provided inside the base body 121a. Therefore, the air discharged from the dust collection motor 145 can flow through the circulation path formed inside the base body 121a and be discharged to the air return port 125b.

[0221] The tilting part 121b can be configured in the base body 121a at the entrance for the robot vacuum cleaner 200 to climb.

[0222] The tilting portion 121b can tilt forward in the direction in which the robot vacuum cleaner 200 enters. More specifically, the front end of the inlet side of the tilting portion 121b can be connected to the ground without any height difference, but it tilts upward more and more towards the front in the direction in which the robot vacuum cleaner 200 enters. In this case, the front in the direction in which the robot vacuum cleaner 200 enters represents the rear when the robot vacuum cleaner base station 100 is used as a reference. Therefore, the robot vacuum cleaner 200 can easily climb from the ground to the robot vacuum cleaner base station 100.

[0223] A wheel guide 121ba may be provided in the inclined section 121b.

[0224] 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.

[0225] An auxiliary wheel guide 121bb may be provided in the inclined section 121b.

[0226] 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.

[0227] 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.

[0228] 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.

[0229] 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.

[0230] The agitator receiving portion 121d can accommodate at least a portion of the agitator 250 of the robotic vacuum cleaner 200. Specifically, the agitator receiving portion 121d can provide space for the lower end of the agitator 250 of the robotic vacuum cleaner 200 to be accommodated when the wheels 260 of the robotic vacuum cleaner 200 are mounted in the wheel engagement portion 121c.

[0231] An agitator receiving portion 121d can be formed between the wheel engagement portions 121c. The agitator receiving portion 121d can be shaped to correspond to the agitator 250 of the 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.

[0232] The agitator receiving portion 121d may include a recessed portion 121da and a protruding portion 121db.

[0233] A recess 121da can be formed from the base 121. The recess 121da can form a receiving space for accommodating at least a portion of the agitator 250. In this way, with the wheels 260 of the sweeping robot 200 mounted in the wheel engagement portion 121c, at least a portion of the agitator 250 can be accommodated in the receiving space of the recess 121da.

[0234] The receiving space of the recess 121da can communicate with the receiving space S of the placement part 120.

[0235] The protrusion 121db can be formed by protruding from the base 121. The protrusion 121db can be arranged along the edge of the recess 121da. In addition, when the agitator 250 is accommodated in the accommodating space of the recess 121da, the protrusion 121db can be arranged at a predetermined distance from the main body 210 of the robot vacuum cleaner 200.

[0236] The protrusion 121db can guide the air discharged through the air return port 125b to the suction section 211 of the robot vacuum cleaner 200. In this way, the air discharged into the receiving space of the recess 121da can be guided by the protrusion 121db to the suction section 211 of the robot vacuum cleaner 200.

[0237] 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 may connect the recess 121da and the dust collection motor 145 through a circulation path. The recess 121da and the circulation path may be connected through the air return port 125b. Therefore, air discharged from the dust collection motor 145 may pass through the air return port 125b and be discharged into the recess 121da of the agitator housing 121d.

[0238] 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.

[0239] A dust passage hole 123a can be formed in the placement 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. The dust passage hole 123a can communicate with the dust bin 220 of the robotic vacuum cleaner 200. The dust passage hole 123a can communicate with the dust outlet 221 of the dust bin 220 of the robotic vacuum cleaner 200. The dust passage hole 123a can be formed with a hole shape corresponding to the shape of the dust bin 220 so that dust from the dust bin 220 flows into the dust collection section 140. The dust passage hole 123a can be formed with a shape corresponding to the dust outlet 221 of the dust bin 220. The dust passage hole 123a can be formed to communicate with a dust collection flow path (not shown). Air drawn in through the dust passage hole 123a can flow through the dust collection flow path (not shown) and then be discharged through the air return section 125.

[0240] 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.

[0241] 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.

[0242] The robot vacuum cleaner base station 100 may also include a water supply nozzle 123c.

[0243] The water supply nozzle 123c can be connected to the supply section 231 of the water tank 230 of the robotic vacuum cleaner 200. Specifically, the water supply nozzle 123c can be connected to the inlet of the water tank 230. The inlet is configured to connect to the water tank 230 of the robotic vacuum cleaner 200. The water supply nozzle 123c can supply water supplied from the water supply pipe of the kitchen cabinet 2 to the storage space inside the water tank 230 of the robotic vacuum cleaner 200.

[0244] 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 on the left and right sides of the base 121. The height of the inner wall 124 can be formed corresponding to the height of the platform 21. Specifically, the height of the inner wall 124 can be the same as the height of the platform 21.

[0245] On the other hand, various components such as a dust collection path (not shown), a dust collection unit 140, a dust collection motor 145, a detergent tank 163, and a wastewater tank 164 can be arranged on the outer side of the inner wall 124. Specifically, the space between the inner wall 124 and the outer wall 111 of the cover 110 can accommodate the dust collection unit 140, the detergent tank 163, and the wastewater tank 164.

[0246] 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 left-right width of the dust collection section 140 and the detergent container 163 can be formed corresponding to the distance between the inner wall 124 and the outer wall 111 of the cover 110.

[0247] 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.

[0248] The washing board 122 can be a board that is sloping downwards towards the center.

[0249] 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.

[0250] 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.

[0251] 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.

[0252] 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.

[0253] With this configuration, the flow of washing water and / or air can be guided by 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. Thus, heated air can be supplied to the washing tank 128 after passing through the through hole 122b.

[0254] Therefore, if the drive unit of the sweeping unit 240 is driven to rotate while the mop 242 of the robot vacuum cleaner 200 is positioned on the washing plate 122, the mop 242 will rotate. At this time, if the mop 242 rotates while water is being supplied to the washing plate, the mop 242 can be washed while rubbing against the stationary washing protrusions 122a.

[0255] 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.

[0256] The cleaning tank 128 may include a base surface for fluid flow through the washing plate 122 and a cleaning tank wall extending vertically from the outer contour of the base surface. The closer the base surface is to the rear of the robot vacuum cleaner base station 100, the lower its height above the ground (kitchen floor). This allows the fluid flowing through the washing plate 122 to be collected at the rear of the cleaning tank 128 and then discharged to the outside through the wastewater inlet 164c, described later.

[0257] Dust collection section

[0258] Figure 12 and Figure 13A side view of the dust collection section of the robot vacuum cleaner base station, used to illustrate an embodiment of the present invention, is shown. Figure 14 A cross-sectional view of the dust collection flow path of a robot vacuum cleaner base station used to illustrate an embodiment of the present invention is shown.

[0259] Reference Figures 12 to 14 as well as Figure 17 The dust collection unit 140 is described below.

[0260] 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 cover 110. The dust collection unit 140 can also be disposed outside the placement part 120. In this case, the receiving space S can be disposed inside the placement part 120.

[0261] The dust collection unit 140 may include a dust collection unit cover 141, a dust bag (not shown), a filter 142, and a dust bag drawer 144.

[0262] The dust collection unit cover 141 can form a space inside that can accommodate a dust bag (not shown), a filter 142, and a dust bag drawer 144.

[0263] The dust collection unit cover 141 can be internally extended to form a dust bag drawer 144, which can store dust bags (not shown). For example, the dust collection unit cover 141 can be formed into a rectangular tube with an open front, and the rear internal space can be connected to the first dust collection flow path 147 and the second dust collection flow path 148.

[0264] One side of the interior of the dust collection hood 141 can be connected to the first dust collection flow path 147, and the other side can be connected to the second dust collection flow path 148. In addition, if a dust bag (not shown) is attached to the dust collection hood 141, the dust bag (not shown) can be connected to the first dust collection flow path 147 inside the dust collection hood 141.

[0265] A dust bag (not shown) can refer to a bag that collects dust sucked from inside the dust bin 220 of the robotic vacuum cleaner 200 using a dust collection motor 145. The dust bag (not shown) can be detachably attached to the dust collection cover 141. Therefore, after a dust bag (not shown) is detached from and discarded from the dust collection cover 141, a new dust bag (not shown) can be attached to the dust collection cover 141. That is, the dust bag (not shown) can be considered a consumable part.

[0266] The dust bag (not shown) can be configured to increase in size and contain the dust if suction is generated using the dust collection motor 145.

[0267] Therefore, the dust bag (not shown) can be made of a material that allows air to pass through but prevents foreign objects such as dust from passing through. For example, the dust bag (not shown) can be made of non-woven fabric, and when the volume increases, it can have a hexahedral shape corresponding to the shape of the dust collection unit cover 141.

[0268] Filter 142 can be configured between the dust collection hood 141 and the second dust collection flow path 148. Filter 142 can be configured at the air outlet 141b. Filter 142 can be a pre-filter or a high-efficiency particulate air (HEPA) filter. Air that has passed through the dust bag (not shown) can flow into the second dust collection flow path 148 via filter 142.

[0269] The dust bag drawer 144 can be combined to be extended from the dust collection unit cover 141, and the dust bag (not shown) can be accommodated inside.

[0270] At this time, refer to Figure 17 The dust bag drawer 144 includes a dust bag drawer body 144a, a handle 144d, and a drawer slide 144e.

[0271] The dust bag drawer body 144a can provide internal space for the dust bag (not shown). For example, the dust bag drawer body 144a can be formed as a box with an open upper side, and an air inlet 144b and an air outlet 144c can be formed at the rear to communicate with the first dust collection path 147 and the second dust collection path 148.

[0272] For example, the left-right width of the upper side of the dust bag drawer body 144a can be different from the left-right width of the lower side. For example, the left-right width of the upper side of the dust bag drawer body 144a can be greater than the left-right width of the lower side. That is, a step can be formed inside the dust bag drawer body 144a. In this way, the upper space where the dust bag (not shown) is installed can be maximized, and a flow path can be formed that allows the air passing through the dust bag (not shown) to be easily discharged to the lower side.

[0273] The upper side of the dust bag drawer body 144a can be connected to the first dust collection path 147 via an air inlet 144b. The air inlet 144b can be configured to guide air flowing in the first dust collection path 147 into the interior of the dust bag (not shown). The air inlet 144b allows the first dust collection path 147 to connect with the dust bag (not shown). Therefore, dust sucked in from the dust bin 220 of the robotic vacuum cleaner 200 can move into the interior of the dust bag (not shown) via the first dust collection path 147 and the air inlet 144b.

[0274] The dust bag drawer 144 can communicate with the second dust collection path 148 via an air outlet 144c formed on its lower side. The air outlet 144c can be configured to direct air passing through the dust bag drawer 144 to the second dust collection path 148. The air outlet 144c and the air inlet 144b can be positioned at different heights. The air outlet 144c can be configured to be lower than the air inlet 144b. The air outlet 144c allows the internal space of the dust bag drawer 144 to communicate with the second dust collection path 148. Therefore, air filtered of dust while passing through the dust bag (not shown) can move to the second dust collection path 148 via the air outlet 144c.

[0275] A handle 144d may be provided on the front of the dust bag drawer body 144a. The handle 144d may be configured to be gripped by a user. For example, the handle 144d may include a pair of connecting parts that are hinged to the front of the dust bag drawer body 144a and a gripping part that connects the pair of connecting parts and is formed to be gripped by a user.

[0276] With this configuration, if the user grasps the handle and pulls it forward, the dust bag drawer body 144a can be pulled forward and extended together. Therefore, according to this invention, the user can easily pull the dust bag drawer 144 forward and then lift it upward to easily remove and replace the dust bag (not shown).

[0277] The left and right sides of the dust bag drawer body 144a can be provided with drawer slides 144e. The drawer slides 144e can guide the movement of the dust bag drawer body 144a.

[0278] For example, drawer slides 144e can be formed in the form of grooves or ribs on the left and right sides of the dust bag drawer body 144a along the front and back directions.

[0279] With the above configuration, when the user attaches the dust bag drawer 144 to the dust collection unit cover 141, it can be attached to the correct position, so that the dust collection unit 140, the first dust collection flow path 147 and the second dust collection flow path 148 are connected in the correct position, thereby reducing flow loss.

[0280] On the other hand, corresponding to the drawer slide 144e, a track (not shown) may also be formed on the inner side of the dust collection cover 141. The track (not shown) of the dust collection cover 141 can be formed in a shape and position corresponding to the drawer slide 144e. For example, if the drawer slide 144e is formed in the form of a groove, the track (not shown) of the dust collection cover 141 can be formed in the form of a rib or a protruding sill.

[0281] On the other hand, the robotic vacuum cleaner base station 100 may include a dust collection path. The dust collection path can refer to the path through which air drawn in through the dust through-hole 123a flows via a dust bag to the dust collection motor 145.

[0282] 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 dust collection motor 145.

[0283] The first dust collection path 147 can connect the dust bin 220 of the robotic vacuum cleaner 200 with the internal space of the dust collection cover 141. The first dust collection path 147 can connect the dust bin 220 of the robotic vacuum cleaner 200 with the internal space of the dust collection cover 141. The first dust collection path 147 can also connect the dust passage hole 123a of the placement part 120 with the internal space of the dust collection cover 141. The first dust collection path 147 can represent the space between the dust bin 220 and the dust collection cover 141 of the robotic vacuum cleaner 200. The first dust collection path 147 can be formed in a near-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 flow path formed by bending 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.

[0284] The dust inlet 141a can be configured on the rear side of the dust collection unit cover 141. The first dust collection path 147 can communicate with the dust collection unit cover 141 via the dust inlet 141a. The dust inlet 141a can be combined with a dust bag (not shown). Air containing dust from the dust bin 220 of the robot vacuum 200 can be collected into the dust bag (not shown) via the dust inlet 141a. Furthermore, the dust inlet 141a can be configured in the same position as the dust inlet 144b of the dust bag drawer 144 when combined with the dust bag drawer 144.

[0285] The dust inlet 141a may include a rubber cover covering the dust inlet 141a. The rubber cover may be rotatably attached to the dust inlet 141a. If air flows into the dust inlet 141a, the rubber cover can be rotated to allow air to pass through. When no air flows into the dust inlet 141a, the rubber cover may be in the state of covering the dust inlet 141a. With this configuration, it is possible to prevent air inside the dust collection shroud 141 from flowing back towards the first dust collection path 147.

[0286] The second dust collection path 148 can connect the internal space of the dust collection unit cover 141 to the dust collection motor 145. The second dust collection path 148 can be formed in a near-horizontal direction. In this case, the first dust collection path 147 and the second dust collection path 148 can be formed at different heights. The first dust collection path 147 and the second dust collection path 148 can be formed in a stacked structure. The second dust collection path 148 can be configured to be lower than the first dust collection path 147. With the above configuration, the lateral width and overall volume of the robotic vacuum cleaner base station 100 can be minimized.

[0287] Air outlet 141b can be disposed on the rear side of dust collection unit cover 141. The second dust collection flow path 148 can communicate with dust collection unit cover 141 via air outlet 141b. Air outlet 141b can be disposed at a position closer to the lower side than dust inlet 141a. Furthermore, air outlet 141b can be disposed at the same position as air outlet 144c of dust bag drawer 144 when combined with it.

[0288] The dust collection module can provide suction airflow to the dust collection path.

[0289] Specifically, the dust collection module may include a dust collection motor cover 146 and a dust collection motor 145.

[0290] The dust collection motor housing 146 can be configured inside the housing 110. The dust collection motor housing 146 can house the dust collection motor 145 inside.

[0291] The internal space of the dust collection motor housing 146 can be connected to the second dust collection flow path 148. Therefore, the air flowing in the second dust collection flow path 148 can be directed to the dust collection motor 145.

[0292] The internal space of the dust collection motor housing 146 can be connected to the circulation path. Therefore, air that has passed through the dust collection motor 145 can be directed to the circulation path.

[0293] The dust collection motor 145 can generate suction in the dust collection flow path.

[0294] 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 to suck up dust from the dust bin 220 of the robot vacuum cleaner 200.

[0295] The dust collection motor 145 can generate suction by rotating. As an example, the dust collection motor 145 can be formed in a shape similar to a cylinder.

[0296] 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 circulation flow path. When the dust collection motor 145 is driven, the air flowing in the second dust collection flow path 148 can flow into the interior of the dust collection motor housing 146. In addition, the air flowing into the interior of the dust collection motor housing 146 can be discharged to the air return port 125b after flowing through the circulation flow path via the dust collection motor 145.

[0297] On the other hand, the rotation axis of the dust collection motor 145 can be configured to be nearly horizontal. With the above configuration, the overall volume of the robot vacuum base station 100, which is installed in the cabinet 2 or the installation space 21a of the structure, can be minimized.

[0298] On the other hand, according to an 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.

[0299] The air return section 125 can direct the air expelled from the dust collection motor 145 to the robot vacuum cleaner 200.

[0300] The air return section 125 can be composed of a circulation path and an air return port 125b.

[0301] The circulation path provides a flow path for the air discharged from the dust collection motor 145. The circulation path can be configured inside the base body 121a.

[0302] The circulation path can be connected to the flow path of the dust collection motor 145. The circulation path can refer to the flow path connecting the internal space of the dust collection motor housing 146 and the air return port 125b. One end of the circulation path can communicate with the internal space of the dust collection motor housing 146, and the other end of the circulation path can communicate with the receiving space of the recess 121da.

[0303] The circulation path can be a horizontally formed path inside the housing 110. The circulation path can be connected to the flow path of the dust collection motor 145. Specifically, one end of the circulation path can communicate with the internal space of the dust collection motor housing 146, and the other end of the circulation path can communicate with the air return port 125b.

[0304] The air return port 125b can serve as an outlet to guide the air discharged from the dust collection motor 145 to the receiving space of the recess 121da.

[0305] An air return port 125b may be formed on the base 121. An air return port 125b may be formed on the agitator housing 121d. An air return port 125b may be formed on the side wall of the recess 121da.

[0306] The circulating flow path of this utility model embodiment can direct the air discharged from the dust collection motor 145 to the suction section 211 of the sweeping robot 200.

[0307] The circulating flow path 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.

[0308] 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 circulation flow path, and the air return port 125b before being discharged into the receiving space S.

[0309] 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.

[0310] Cleaning cloth washing section

[0311] Figure 15 An enlarged view of the mop washing unit of the robot vacuum cleaner base station used to illustrate an embodiment of the present invention is shown. Figure 16 An enlarged view of the washing water supply unit of the mop washing section of the robot vacuum cleaner base station, used to illustrate an embodiment of the present invention, is shown. Figure 17 A diagram is shown illustrating the state of the dust collection unit and detergent tank extending from the base station of the sweeping robot according to an embodiment of the present invention.

[0312] Reference Figures 15 to 17 The following is a description of the mop washing section 160 of the robot vacuum cleaner base station 100 according to an embodiment of the present invention.

[0313] The robot vacuum cleaner base station 100 of this embodiment may include a cloth washing unit 160. The cloth washing unit 160 can wash the cloth 242 of the robot vacuum cleaner 200 attached to the mounting unit 120.

[0314] The rag washing unit 160 may include: a washing water supply unit 161 that discharges washing water to the washing plate 122; a detergent tank 163 that stores liquid containing detergent; and a wastewater tank 164 that stores the washing water after the rags 242 have been washed.

[0315] The washing water supply unit 161 can generate washing water for washing the rags 242 by mixing clean water and detergent.

[0316] The washing water supply unit 161 includes a branch flow path 161a, a clean water inlet 161b, a detergent inlet 161c, a detergent pump 161d, and a washing water outlet 161e.

[0317] At this time, a pair of washing water outlets 161e can be arranged spaced apart on the rear side of the connecting wall 123. The washing water outlets 161e can discharge washing water from the upper side of the washing plate 122. For example, a pair of washing water outlets 161e can be arranged on the upper side of a pair of washing protrusions 122a.

[0318] At this time, the purified water supplied from the water supply pipe of the kitchen cabinet 2 and passing through the regulator 162 can be connected to the respective washing water outlets 161e, which are arranged separately and branch off to both sides, through the branch flow path 161a. That is, the branch flow path 161a can be formed into a single pipe branching into two, in which case either end of the branch can be connected to either of the pair of washing water outlets 161e, and the other end of the branch can be connected to the other of the pair of washing water outlets 161e. Thus, the branch flow path 161a can supply washing water to the pair of washing water outlets 161e.

[0319] The washing water outlet 161e can be integrally formed with the connecting wall 123 on the rear side of the connecting wall 123, or it can be detachably connected to the connecting wall 123.

[0320] The purified water inlet 161b is configured to direct purified water supplied from the water supply pipe of the kitchen cabinet 2 to the washing water supply section 161. Specifically, the water supply pipe of the kitchen cabinet 2 can be connected to a regulator 162 to regulate the flow rate supplied from the water supply pipe. In addition, a portion of the purified water passing through the regulator 162 can be supplied to the water tank 230 of the robot vacuum cleaner 200 through the water supply nozzle 123c, while another portion can flow into a pair of washing water supply sections 161 arranged separately from each other through the purified water inlet 161b.

[0321] The detergent inlet 161c is configured to direct the detergent-containing liquid supplied from the detergent tank 163 to the wash water supply unit 161. Specifically, the detergent-containing liquid stored in the detergent tank 163 can be supplied to the wash water supply unit 161 via the detergent pump 161d.

[0322] Additionally, the detergent and purified water flowing into the washing water supply unit 161 can be mixed and used as washing water. The washing water supply unit 161 can discharge washing water to the top surface of the washing plate 122 through the washing water discharge port 161e. The washing water discharge port 161e can be opened towards the top surface of the dishcloth 242 placed on the washing plate 122.

[0323] Detergent container 163 can store liquid containing detergent.

[0324] Detergent container 163 includes detergent container body 163a, handle 163b and detergent container track 163c (see reference). Figure 17 ).

[0325] The detergent container body 163a can provide a space for storing liquid containing detergent. For example, the detergent container body 163a can be formed as a box with an open top, and can be connected to the washing water supply unit 161 at the rear.

[0326] 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 include a pair of connecting parts that are hinged to the front of the detergent container body 163a and a gripping part that connects the pair of connecting parts and is formed to be gripped by a user.

[0327] With this configuration, if the user grasps the handle and pulls it forward, the detergent container body 163a can also be pulled forward and extended. Therefore, according to this invention, the user can easily pull the detergent container 163 forward to dispense detergent.

[0328] Detergent tub body 163a may have detergent tub tracks 163c formed on its left and right sides. Detergent tub tracks 163c can guide the movement of detergent tub body 163a.

[0329] 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.

[0330] 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.

[0331] 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.

[0332] The wastewater tank 164 provides space for storing the washing water from washing the cloths 242. The washing water discharged onto the top surface of the washing plate 122 can be discharged through the through-hole 122b after the washing of the cloths 242 is finished, following the incline of the washing plate 122. The washing water passing through the through-hole 122b can accumulate in the washing tank 128. Additionally, the washing water accumulated in the washing tank 128 can flow into the wastewater suction flow path 164b through the wastewater inlet 164c, and then into the wastewater tank 164 through the wastewater inlet flow path 164b. In other words, the liquid passing through the washing plate 122 can flow along the washing tank 128 and be discharged through the wastewater inlet 164c.

[0333] On the other hand, a sewage suction flow path 164b is formed in a sewage suction pipe, with one end of the sewage suction pipe connected to a sewage inlet 164c and the other end connected to a sewage tank 164. 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 164b can be configured under the external gas supply module 171. Alternatively, the sewage suction flow path 164b can be configured under the external gas supply flow path 171a.

[0334] Washing water stored in the wastewater tank 164 can be discharged to the drain pipe 25 of the kitchen cabinet 2 through the wastewater discharge path 164a. One end of the wastewater discharge path 164a can be connected to the wastewater tank 164, and the other end can be connected to the drain pipe 25. At this time, the washing water stored in the wastewater tank 164 can be used by a centrifugal pump (not shown) to flow through the wastewater discharge path 164a and be discharged to the drain pipe.

[0335] The sewage discharge path 164a connected to the sewage tank 164 can be connected to the upstream 25b of the drain pipe 25 of the kitchen cabinet 2, based on the water trap 25a. This is because if the sewage discharge path 164a is connected to the downstream 25c of the drain pipe 25, based on the water trap 25a, foul odors or fluids inside the drain pipe 25 may flow back into the sewage discharge path 164a.

[0336] Additionally, the cloth washing unit 160 may include a check valve (not shown). The check valve prevents fluid inside the drain pipe 25 from flowing back into the sewage discharge path 164a. The check valve may be located at the other end of the sewage discharge path 164a connected to the drain pipe 25.

[0337] On the other hand, the detergent tank 163 and the wastewater tank 164 can be accommodated in the space formed between the inner wall 124 and the outer wall 111 of the 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 164 can be disposed on the upper side of the detergent tank 163 in the space between the inner wall 124 and the outer wall 111 of the cover.

[0338] Cloth Drying Section

[0339] Figure 18 A perspective view of the cloth drying unit of the robot vacuum cleaner base station, used to illustrate an embodiment of the present invention, is shown. Figure 19 An enlarged view of the cloth drying section of the robot vacuum cleaner base station according to an embodiment of the present invention is shown. Figure 20 A cross-sectional view is shown to illustrate the flow of air into the hot gas supply module according to an embodiment of the present invention.

[0340] Reference Figures 18 to 20 In one embodiment of the present invention, the robot vacuum cleaner base station 100 may include a cloth drying unit 170. At this time, the cloth drying unit 170 can dry the cloth 242 of the robot vacuum cleaner 200 that has been washed by the cloth washing unit 160 or the cloth 242 that is wet after completing wet cleaning operations.

[0341] A cloth drying unit 170 of this utility model may include an external gas supply module 171, an air exhaust unit 172, a circulating fan 173, and a check valve 175.

[0342] The external gas supply module 171 can supply hot gas to the accommodating space S, and 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 171e.

[0343] 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.

[0344] The external gas supply path 171a can connect the external space of the enclosure 110 with the containment space S. 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.

[0345] 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.

[0346] 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.

[0347] 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.

[0348] 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.

[0349] The blower fan 171e can be configured on the external gas supply flow path 171a to blow air into the containment space S. If the blower fan 171e 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.

[0350] 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.

[0351] 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.

[0352] The air exhaust unit 172 can discharge the hot and humid air generated inside the robot vacuum base station 100 during the drying of the mop 242 to the drain pipe 25. Specifically, the air exhaust unit 172 can be connected to the drain pipe 25 of the accommodating space S and the kitchen cabinet 2.

[0353] The air exhaust section 172 may have an air exhaust flow path. At this time, one end of the air exhaust flow path may be connected to the receiving space S, and the other end may be connected to the drain pipe 25. Specifically, the air intake 172a, which is one end of the air exhaust flow path, may be connected to the receiving space S, and the air exhaust outlet 172b, which is the other end, may be connected to the drain pipe 25.

[0354] On the other hand, the air intake 172a can be disposed at various positions on the accommodating space S. For example, the air intake 172a can be disposed on the connecting wall 123. For another example, the air intake 172a can be disposed on the inner wall 124. As yet another example, the air intake 172a can be disposed at a position higher than the cloth 242 above the ground, or at a position closer to the front than the external air discharge section 171c. In this way, air containing steam generated during the drying of the cloth 242 can be discharged.

[0355] The air exhaust section 172 can be connected to the downstream 25c of the drain pipe 25 of the kitchen cabinet 2, based on the water trap 25a. This is because, if the air exhaust section 172 is connected to the upstream 25b of the drain pipe 25, based on the water trap 25a, the hot air exhausted through the air exhaust section 172 may be unable to pass through the drain pipe 25 due to the water accumulated in the water trap 25a.

[0356] On the other hand, in one embodiment of the present invention, the air exhaust path can be divided into two branches inside the cover 110, penetrating both sides of the cover 110. In this case, either branch can penetrate the left outer wall of the cover 110, and the other branch can penetrate the right outer wall of the cover 110. The air exhaust portion 172 penetrating the outer walls 111 on both sides of the cover 110 can be connected to the drain pipe 25. Therefore, the air drawn in from the air exhaust portion 172 can flow to the air exhaust ports 172b of the two branches and then be discharged downstream 25c based on the water trap 25a of the drain pipe 25.

[0357] The circulating fan 173 can discharge air flowing in through the air intake 172a to the drain pipe 25. The circulating fan 173 can circulate the air flowing into the air exhaust section 172. The circulating fan 173 can be installed on the air exhaust flow path.

[0358] If the circulating fan 173 is driven, air in the accommodating space S can flow into the air intake 172a. The air flowing into the air intake 172a can flow through the air exhaust section 172 and then be discharged into the drain pipe 25. Specifically, by driving the circulating fan 173, the air flowing in the air exhaust section 172 can be discharged downstream 25c relative to the water trap 25a of the drain pipe 25.

[0359] The cloth drying unit 170 may include a check valve 175. The check valve 175 may be located at the other end of the air discharge path connected to the drain pipe 25. This prevents fluid inside the drain pipe 25 from flowing back to the air discharge unit 172.

[0360] layout

[0361] Figure 21 and Figure 22 A diagram illustrating the configuration relationship of the robot vacuum cleaner base station on a horizontal plane is shown.

[0362] Reference Figure 4 , Figure 21 as well as Figure 22 The configuration of the robot vacuum cleaner base station 100 in this embodiment of the present invention is described below.

[0363] The feature of this utility model embodiment is that the robot vacuum cleaner base station 100 is installed in the lower space of the kitchen cabinet 2.

[0364] Therefore, the present invention is characterized in that the robot vacuum cleaner base station 100 is configured horizontally in a space matching the space between the lower side panel 23 of the kitchen cabinet 2 and the kitchen floor.

[0365] 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.

[0366] At this time, when both the dust collection unit 140 and the cloth washing unit 160 are provided, the placement unit 120 can be arranged between the dust collection unit 140 and the cloth washing unit 160.

[0367] For example, an entrance / exit 127 and a door 126 can be configured at the front of the robot vacuum base station 100. Additionally, a mounting section 120 can be configured for the robot vacuum 200 to connect to the rear from the entrance / exit 127. In this case, the dust collection section 140 can be configured from the front to the rear of the robot vacuum base station 100 for a predetermined length. Furthermore, the mop washing section 160 can also be configured from the front to the rear of the robot vacuum base station 100 for a predetermined length.

[0368] Therefore, when looking at 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.

[0369] At this time, the dust bag (not shown) of the dust collection unit 140 can be configured to extend forward of the cover 110. In addition, the detergent container 163 of the cloth washing unit 160 can be configured to extend forward of the cover.

[0370] That is, a handle 144d can be provided at the front end of the dust collection section 140 so that the user can hold the dust collection section cover 141. In addition, a handle 163b can also be provided at the front end of the cloth washing section 160 so that the detergent bucket 163 can be pulled.

[0371] The above configuration provides the convenience that when a user wants to pull out the dust bag (not shown) or detergent container 163, the pull-out position can be immediately identified, and the dust bag (not shown) or detergent container 163 can be pulled out with a simple action of pulling the handle.

[0372] 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, it is easy to connect the power supply wire to the dust collection motor 145. In addition, it has the effect of minimizing the overall space occupied by the mounting section 120, the dust collection hood 141, and the dust collection motor 145 within a limited space.

[0373] Furthermore, at least a portion of a flow path for the flow of washing water for washing the cloth 242 and a pump that provides the flow force for the washing water 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 in from the water supply pipe can be minimized. Additionally, it has the effect of minimizing the overall space occupied by the housing 120, the detergent tank 163, and the flow path for the washing water within a limited space.

[0374] 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.

[0375] Therefore, in the sweeping robot base station 100 of this utility model embodiment, the left and right sides based on the placement part 120 can be equipped with a dust collection part 140 and a cloth washing part 160, and the rear side can be equipped with a cloth drying part 170.

[0376] That is, in the sweeping robot base station 100 of this utility model embodiment, the dust collection unit 140, the rag washing unit 160 and the rag drying unit 170 can all be arranged within a specified distance range from the outer contour of the placement unit 120.

[0377] With this configuration, the placement unit 120, dust collection unit 140, cloth washing unit 160, and cloth drying unit 170 can all be arranged in the narrowest space on the horizontal plane.

[0378] 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, it minimizes the distance between the mop 242 and the mop washing unit 160, as well as the distance between the mop 242 and the mop drying unit 170, thus restricting the area where washing water and wastewater from washing are present.

[0379] In addition, with this configuration, the sweeping robot base station 100 of this utility model can have all its components arranged within a limited height.

[0380] Specifically, based on the state where the robotic vacuum cleaner 200 is integrated with the mounting section 120, at least a portion of the dust collection section 140 can be configured to be lower than the uppermost point of the robotic vacuum cleaner 200. Additionally, at least a portion of the mop washing section 160 can be configured to be lower than the uppermost point of the robotic vacuum cleaner 200. Furthermore, at least a portion of the mop drying section 170 can be configured to be lower than the uppermost point of the robotic vacuum cleaner 200.

[0381] Furthermore, based on the state where the robot vacuum cleaner 200 is integrated with the mounting section 120, the top of the robot vacuum cleaner 200 can be configured to be higher than the dust bag drawer 144. Additionally, the top of the robot vacuum cleaner 200 can be configured to be higher than the detergent dispenser 163. Furthermore, the top of the dust bag drawer 144 can be configured to be higher than the detergent dispenser 163.

[0382] As a result, the robot vacuum base station 100 of this embodiment can be equipped with a dust collection unit 140, a mop washing unit 160, and a mop drying unit 170 on three sides of the surrounding placement part 120, excluding the front side where the robot vacuum 200 enters. This configuration has the following effects: even with limited vertical height, it can not only charge the robot vacuum 200 using minimal horizontal space, but also collect dust from the robot vacuum 200, wash the mop 242, and dry the mop 242.

[0383] drawer

[0384] When the charging dock for a robotic vacuum cleaner is positioned under a kitchen cabinet, it can provide a decorative effect by minimizing external exposure. However, if the robotic vacuum cleaner malfunctions while under the cabinet or if the charging dock itself malfunctions, it can be difficult for the user to remove and repair it. To solve this problem, this invention adds a drawer 190 to the robotic vacuum cleaner base station 100.

[0385] In this regard, Figure 23 A diagram is shown illustrating the state in which a drawer is provided in the base station of a sweeping robot according to an embodiment of the present invention. Figure 24 A diagram is shown illustrating the state of the drawer extending from the base station of the sweeping robot according to an embodiment of the present invention.

[0386] Reference Figure 23 and Figure 24 The drawer 190 of the robot vacuum cleaner base station 100 according to an embodiment of the present invention is described below.

[0387] 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.

[0388] With drawer 190 introduced into cover 110, if robot vacuum 200 enters placement section 120, door 126 can be closed. In this case, robot vacuum 200 can be blocked from the inside and outside of cover 110 by door 126.

[0389] This prevents dust from scattering to the outside of the robot vacuum base station 100 during the dust collection process of the robot vacuum 200 inside the dust bin 220. Additionally, it prevents wastewater from leaking to the outside of the robot vacuum base station 100 during the washing of the mop cloth 242.

[0390] 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.

[0391] 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.

[0392] At this time, with the door 126 closing the entrance 127, if the drawer 190 is pulled out from the cover 110, the robot vacuum cleaner 200 located in the placement section 120 can be exposed to the outside.

[0393] 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.

[0394] On the other hand, in one embodiment of the present invention, the drawer 190 can be drawn out with a dust collection section 140 provided inside. That is, the drawer 190 can be drawn out together with the dust collection section 140.

[0395] Conversely, the dust collection section 140 of this invention can be separately extended from the cover 110 and the drawer 190. In this case, the extension direction of the dust collection section 140 can be parallel to the extension direction of the drawer 190. For example, the extension direction of the dust bag drawer 144 can be parallel to the extension direction of the drawer 190.

[0396] Furthermore, in one embodiment of the present invention, the drawer 190 can be drawn out with at least a portion of the cloth washing section 160 internally provided. That is, the drawer 190 can be drawn out together with at least a portion of the cloth washing section 160. For example, the drawer 190 can be drawn out together with the detergent container 163 and the wastewater container 164.

[0397] Conversely, the detergent container 163 of this invention can be pulled out separately from the cover 110 and the drawer 190. In this case, the direction in which the detergent container 163 is pulled out can be parallel to the direction in which the drawer 190 is pulled out.

[0398] With the above configuration, the robot vacuum cleaner base station 100 of one embodiment of the present invention can be configured such that the drawer 190, the dust collection part 140 and the detergent bucket 163 are all parallel in their outward directions.

[0399] Therefore, the robot vacuum cleaner base station 100 of this invention allows users to easily identify the direction of its constituent elements, and facilitates easy repair and warranty maintenance.

[0400] Drawer 190 may include drawer sidewall 191, joint 192, and drawer slide 193.

[0401] The drawer sidewalls 191 are configured to move relative to the outer wall surface of the cover 110. For example, a pair of drawer sidewalls 191 may be configured to face one pair of outer wall surfaces of the cover 110.

[0402] At this time, the pair of drawer sidewalls 191 can be positioned closer to the inner side of the robot vacuum base station 100 than 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.

[0403] At this time, the pair of drawer sidewalls 191 can be directly connected to the base 121 of the mounting part 120. In contrast, the pair of drawer sidewalls 191 can be connected by a drawer base (not shown), or they can be combined with the mounting part 120 on the upper side of the drawer base (not shown) and move together.

[0404] On the other hand, a dust collection section 140 and / or a cloth washing section 160 may be arranged between the drawer side wall 191 and the placement section 120. That is, based on the state in which the robot vacuum cleaner 200 is attached to the placement section 120, a dust collection section 140 and / or a cloth washing section 160 may be arranged between the robot vacuum cleaner 200 and the drawer side wall 191.

[0405] With the above configuration, the dust collection unit 140 and the cloth washing unit 160 can be arranged using minimal horizontal space.

[0406] A connector 192 is provided on the drawer side wall 191 and is detachably coupled with at least one of a flexible hose and a wire. For example, the connector 192 may be configured on the drawer side wall 191 and may be coupled with a flexible hose and / or a wire.

[0407] The connector 192 is attached to the drawer side wall 191. One side of the connector 192 can be positioned closer to the inner space of the drawer 190 than the drawer side wall 191, and the other side of the connector 192 is positioned on the outer side of the drawer side wall 191.

[0408] The connector 192 is detachably coupled with at least one of a hose and an electrical wire. For example, the connector 192 may be detachably coupled with at least one of a water supply pipe connection to a water supply pipe, a drain pipe connection to a drain pipe, an exhaust pipe connection to a steam exhaust pipe for venting air from inside the drawer 190, and a power supply connection to a power source.

[0409] At this time, water supply pipes for the dishcloth washing unit 160 and water supply pipes connected to an external water source can be connected to both sides of the water supply pipe connection. In addition, drain pipes for the dishcloth washing unit 160 and drain pipes connected to the upstream 25b of the water trap of the kitchen cabinet 2 can be connected to both sides of the drain pipe connection.

[0410] That is, the connector 192 of this utility model can be a structure in which the water supply pipe and the drain pipe that use the water supply and drain pipe provided in the kitchen cabinet 2 for direct drainage are detachably connected to the water supply and drain pipe inside the robot vacuum base station 100.

[0411] Additionally, air exhaust pipes connected to the air outlet 172b of the cloth drying unit 170 can be attached to both sides of the exhaust pipe connection.

[0412] Therefore, the air discharged from the cloth drying section 170 can be discharged downstream 25c of the water trap.

[0413] In addition, the power connection part can be connected to a wire for connection to an external power source. In this case, the power connection part can be directly connected to the wire, or the wire can be connected using a connector or adapter or other wire connection method.

[0414] Drawer slide 193 can be configured on drawer side wall 191 to guide the movement of drawer side wall 191. Drawer slide 193 can be fixedly attached to drawer side wall 191 or integrally formed with drawer side wall 191, and interact with the slides provided on the outer wall 111 of cover 110 to guide the movement path of drawer side wall 191. On the other hand, this utility model describes the case where slides are provided on drawer 190 and cover 110, but it is not necessarily limited to the form of slides, and can include rollers, guide grooves, or guide ribs that can replace slides.

[0442] Dust collection sterilization module

[0443] Figure 26 This diagram illustrates the state of a dust collection and sterilization module configured in the base station of a sweeping robot according to an embodiment of the present invention.

[0444] Figure 27 This is a diagram illustrating the configuration relationship on the rear side of the dust collection unit cover in a sweeping robot base station according to an embodiment of the present invention.

[0445] Figure 28 This is a diagram illustrating the dust collection and sterilization module in a sweeping robot base station according to an embodiment of the present invention.

[0446] Reference Figures 26 to 28 The following describes the dust collection and sterilization module 130 of the sweeping robot base station 100 according to an embodiment of the present invention.

[0447] The cover 110 can internally house a dust collection section 140 for emptying the dust from the robot vacuum cleaner 200. The dust collection section 140 can collect dust from the dust bin 220 of the robot vacuum cleaner 200.

[0448] A dust collection unit 140 according to an embodiment of the present invention may include a dust collection unit cover 141, a dust bag (not shown), a filter 142, and a dust bag drawer 144. The dust collection unit cover 141 may have an internal space capable of accommodating the dust bag (not shown). The dust collection space may refer to the internal space of the dust collection unit cover 141.

[0449] On the other hand, if foreign objects that have not been sterilized are captured in the dust collection section 140 for an extended period of time, pests and microorganisms may multiply. In particular, mites such as grain mites are microorganisms that parasitize insufficiently dried grains. If grains are captured in the dust collection section 140 in a hot and humid environment, they may easily multiply and potentially move along the flow path of the vacuum cleaner base station and fly outwards.

[0450] To address this problem, a sweeping robot base station 100 according to an embodiment of the present invention may include a dust collection part sterilization module 130 for sterilizing the interior of the dust collection part cover 141.

[0451] The internal sterilization of the dust collection unit cover 141 can be achieved by circulating heated air or by irradiating sterilizing light into the interior. The first, second, and third embodiments of this utility model utilize hot air circulation, while the fourth embodiment utilizes sterilizing light.

[0452] In an embodiment where the dust collection hood 141 is sterilized via hot air circulation, the dust collection sterilization module 130 can be defined as a hot air circulation module. The hot air circulation module may include circulating fans 130a, 1173, 2173 for expelling air into the dust collection hood 141, and heaters 130d, 1171d, 2171d for heating the air. It may also include hot air inlets 141d, 1141d, 2141d that allow heated air to flow into the interior of the dust collection hood 141.

[0453] The dust collection and sterilization module 130 may include a hot air inlet 141d, a hot air outlet 141e, a circulating fan 130a, and a heater 130b.

[0454] The dust collection sterilization module 130 can be configured inside the cover 110 to supply heated air to the dust collection space. The dust collection sterilization module 130 can be connected to the dust collection cover 141 via a hot air inlet 141d and a hot air outlet 141e. The heated air from the dust collection sterilization module 130 can flow into the dust collection space through the hot air inlet 141d. The flowing air can circulate inside the dust collection cover 141 and then be discharged through the hot air outlet 141e. Thus, the interior of the dust collection cover 141 can be sterilized using hot air.

[0455] The dust collection sterilization module 130 can be disposed at the rear of the dust collection unit cover 141. The dust collection motor cover 146 can be disposed inside the cover 110, and houses the dust collection motor 145 inside. As an example, the dust collection motor cover 146 can be disposed on the left rear side of the cover 110. The dust collection sterilization module 130 can be disposed between the dust collection unit cover 141 and the dust collection motor cover 146.

[0456] Air can flow into the dust collection hood 141 through the hot air inlet 141d. The hot air inlet 141d can be formed on the rear side of the dust collection hood 141. As an example, the hot air inlet 141d can be formed on the lower side of the rear side of the dust collection hood 141. Alternatively, the hot air inlet 141d can be formed on the left side of the rear side of the dust collection hood 141.

[0457] Air flowing in from the hot air inlet 141d can be discharged through the hot air outlet 141e. In the robotic vacuum cleaner base station 100 of one embodiment of the present invention, the air flowing in through the hot air inlet 141d can then flow into the dust collection and sterilization module 130. The air can circulate between the dust collection and sterilization module 130 and the dust collection cover 141. The hot air outlet 141e can be formed on the rear side of the dust collection cover 141. The hot air outlet 141e can be formed at a position higher than the hot air inlet 141d relative to the ground. As an example, the hot air outlet 141e can be formed on the upper side of the rear side of the dust collection cover 141. Alternatively, the hot air outlet 141e can be formed on the right side of the rear side of the dust collection cover 141.

[0458] In this context, "left" refers to the left side when looking forward from inside the robot vacuum cleaner base station 100, and "right" can refer to the right side.

[0459] On the other hand, the relationship between the dust collection sterilization module 130 and the dust collection unit 140 is explained.

[0460] The dust collection motor 145 can generate airflow to expel dust from the dust bin 220 of the robotic vacuum cleaner 200 towards the dust collection unit cover 141. A dust collection unit sterilization module 130 can be disposed between the dust collection motor 145 and the dust collection unit cover 141. The dust collection motor 145 can be disposed behind the dust collection unit sterilization module 130.

[0461] A dust inlet 141a may be formed on the rear side of the dust collection unit cover 141. Dust from the dust bin 220 of the robot vacuum cleaner can flow into the dust collection unit cover 141 through the dust inlet 141a. Air generated by the dust collection motor 145 can also flow into the dust collection unit cover 141 through the dust inlet 141a.

[0462] Air outlet 141b can also be configured on the rear side of dust collection unit cover 141. Air flowing into dust inlet 141a can be discharged through air outlet 141b. Specifically, air flowing into dust inlet 141a can pass through a dust bag (not shown) and then be discharged through air outlet 141b. The discharged air can flow to dust collection motor cover 146 through the second dust collection flow path 148.

[0463] In summary, on the rear side of the dust collection cover 141, a dust inlet 141a and an air outlet 141b can be formed to collect dust from the dust bin 220 of the robot vacuum cleaner 200, and a hot air inlet 141d and a hot air outlet 141e can be formed to sterilize the inside of the dust collection cover 141.

[0464] As an example, the hot air inlet 141d can be configured at the lower left end, and the hot air outlet 141e can be configured at the upper right end. In this case, the dust inlet 141a can be configured between the hot air inlet 141d and the hot air outlet 141e.

[0465] That is, the hot air inlet 141d and the hot air outlet 141e can be configured on the rear side of the dust collection hood 141 such that the lateral distance between them is maximized. For example, the hot air inlet 141d and the hot air outlet 141e can be configured at diagonal positions on the rear side of the dust collection hood 141. With this configuration, the air flowing into the dust collection hood 141 can circulate internally along a lateral and vertical expansion path before being discharged to the outside of the dust collection hood 141.

[0466] A circulating fan 130a can be housed inside the dust collection sterilization module 130. The circulating fan 130a can cause air to flow into the interior space of the dust collection housing 141. The circulating fan 130a can cause air to flow into the dust collection space. When the circulating fan 130a is driven, air inside the dust collection sterilization module 130 can flow into the dust collection space through the hot air inlet 141d.

[0467] Heater 130b can be housed inside the dust collection sterilization module 130. Heater 130b can heat the air flowing via the circulating fan 130a. Heater 130b can also heat the air flowing into the dust collection space through the hot air inlet 141d. Heater 130b may include a heater housing and a heating element. The heater housing can be disposed inside the dust collection sterilization module 130, and the interior of the heater housing can have a space for accommodating the heating element. The heating element can heat the air flowing into the heater housing.

[0468] According to one embodiment of the present invention, the circulating fan 130a can be configured at a position higher than the heater 130b relative to the ground. The air blown by the circulating fan 130a can flow towards the heater 130b. After being heated, the air flowing into the heater 130b can flow towards the dust collection hood 141 through the hot air inlet 141d. The air inside the dust collection hood 141 can be blown again by the circulating fan 130a and flow towards the dust collection sterilization module 130 through the hot air outlet 141e.

[0469] Specifically, a circulating fan 130a can be configured behind the hot air outlet 141e, and a heater 130b can be configured behind the hot air inlet 141d. The hot air outlet 141e can be positioned closer to the upper side than the hot air inlet 141d. Furthermore, the circulating fan 130a can be positioned closer to the upper side than the heater 130b. This configuration improves thermal circulation efficiency.

[0470] More specifically, the air heated by heater 130b flows into the lower side of the dust collection hood 141. The heated air moves upwards towards the dust collection hood 141 via convection and flows outwards through the hot air outlet 141e, which is positioned higher than the hot air inlet 141d above the ground. This configuration creates air circulation, thereby improving the sterilization efficiency inside the dust collection hood.

[0471] As another example, at least a portion of the dust collection unit cover 141 can communicate with the outside. When the circulating fan 130a is driven, a negative pressure can be formed inside the dust collection unit cover 141. As a result, outside air can flow into the dust collection unit cover 141. The air flowing into the dust collection unit cover 141 can flow into the dust collection unit sterilization module 130 through the hot air outlet 141e.

[0472] On the other hand, a robotic vacuum cleaner base station 100 according to an embodiment of the present invention may include a dust bag drawer 144. The dust bag drawer 144 may be housed inside the dust collection unit cover 141. The dust bag drawer 144 may be attached to the dust collection unit cover 141 in a forward-extending manner. The dust bag drawer 144 may be in communication with the dust collection unit sterilization module 130 while housed in the dust collection unit cover 141. The dust bag drawer 144 may include a hot air inlet and a hot air outlet separate from the hot air inlet and hot air outlet of the dust collection unit cover 141.

[0473] The hot air inlet can be configured on the rear side of the dust bag drawer 144. The hot air inlet can be configured in the same position as the hot air inlet 141d of the dust collection unit cover 141 when the dust bag drawer 144 is housed inside the dust collection unit cover 141.

[0474] The hot air outlet can be configured on the rear side of the dust bag drawer 144. The hot air outlet can also be configured in the same position as the hot air outlet 141e of the dust collection unit cover 141 when the dust bag drawer 144 is housed inside the dust collection unit cover 141. Therefore, the internal space of the dust bag drawer 144 can communicate with the dust collection unit sterilization module 130 through the hot air inlet and the hot air outlet.

[0475] With the dust bag drawer 144 attached to the dust collection unit cover 141, heated air can flow into the interior space of the dust bag drawer 144 through the hot air inlet. The air flowing in through the hot air inlet can circulate inside the dust bag drawer 144. The air circulating inside the dust bag drawer 144 can then flow back to the dust collection unit sterilization module 130 through the hot air outlet.

[0476] On the other hand, a dust inlet 144b and an air outlet 144c can be formed at the rear of the dust bag drawer 144 to communicate with the first dust collection path 147 and the second dust collection path 148. When the dust bag drawer 144 is attached to the dust collection cover 141, the dust inlet 144b and the air outlet 144c of the dust bag drawer 144 can be respectively arranged at the same positions as the dust inlet 141a and the air outlet 141b of the dust collection cover 141.

[0477] A dust bag (not shown) can be housed inside the dust bag drawer 144 to collect dust from the dustbin 220 of the robotic vacuum cleaner 200. The dust bag (not shown) can be a bag shape with a partial opening. The open portion of the dust bag (not shown) can be detachably connected to the dust inlet 144b of the dust bag drawer 144. That is, the internal space of the dust bag (not shown) can communicate with the dust inlet 144b.

[0478] The dust bag (not shown) can be made of a material that allows air to pass through but prevents foreign objects such as dust from passing through. Air containing dust can flow into the dust bag (not shown) through the dust inlet 144b. At this time, dust that cannot pass through the dust bag (not shown) is captured inside the dust bag (not shown), and the air that has been filtered out of dust can pass through to the outside of the dust bag (not shown). The air that has passed through the dust bag (not shown) can be discharged through the air outlet 144c.

[0479] The internal space of the dust bag drawer 144 can be divided into an internal space for the dust bag (not shown) and an external space for the dust bag (not shown). Air flowing into the hot air inlet of the dust bag drawer 144 circulates within the internal space containing the dust bag (not shown) before being discharged through the hot air outlet of the dust bag drawer 144. That is, the hot air inlet and hot air outlet of the dust bag drawer 144 can communicate with the external space of the dust bag (not shown). Therefore, the air heated by the dust collection sterilization module 130 can sterilize the dust bag (not shown).

[0480] Second Embodiment

[0481] Figure 29a This is a diagram illustrating the external gas supply flow path in the base station of the sweeping robot according to the second embodiment of this utility model. Figure 29b This is a diagram illustrating the first circulation path in the base station of the sweeping robot of the second embodiment of the present invention.

[0482] Reference Figure 29a and Figure 29b The following is a description of the robot vacuum cleaner base station 1100 of the second embodiment of this utility model.

[0483] To avoid repetition, except for the specially described components, the other components and effects in this embodiment are the same as those in an embodiment of the sweeping robot base station of this utility model, and therefore can be cited.

[0484] The dust collection hood 1141 of the second embodiment of this utility model may include a hot air inlet 1141d. Conversely, unlike one embodiment of this utility model, the dust collection hood 1141 may not include a hot air outlet.

[0485] A hot air inlet 1141d may be formed on the rear side of the dust collection unit cover 1141. For example, the hot air inlet 1141d may be formed on the lower side of the rear side of the dust collection unit cover 1141. The hot air inlet 1141d may communicate with the first circulation path 1130c, which will be described later. Air can flow into the interior of the dust collection unit cover 1141 through the hot air inlet 1141d.

[0486] The dust collection and sterilization module 1130 of the second embodiment of this utility model may include a first circulation flow path 1130c and a first flow path switching valve 1130d. Conversely, unlike one embodiment of this utility model, the dust collection and sterilization module 1130 may not include a heater and a circulating fan.

[0487] Correspondingly, the air can be heated by the heater 1171d and the circulating fan 1173 of the cloth drying section 1170. Specifically, the air heated in the cloth drying section 1170 can move to the receiving space S through the external gas supply flow path 1171a to dry the cloth 242.

[0488] The first flow path switching valve 1130d can be operated to separate the cloth drying section 1170 from the external gas supply flow path 1171a, and connect the cloth drying section 1170 to the first circulation flow path 1130c. At this time, heated air can move towards the dust collection section cover 1141 to sterilize its interior.

[0489] That is, in the second embodiment of this utility model, the cloth drying unit 1170 can not only dry the cloth 242, but also sterilize the dust collection unit cover 1141.

[0490] The first circulation path 1130c can connect the cloth drying section 1170 and the dust collection cover 1141. The first circulation path 1130c can communicate with the dust collection cover 1141 through the hot air inlet 1141d. The air heated in the cloth drying section 1170 can move to the dust collection cover 1141 through the first circulation path 1130c.

[0491] The first flow path switching valve 1130d can be configured between the cloth drying unit 1170, the external gas supply flow path 1171a, and the first circulation flow path 1130c. The first flow path switching valve 1130d can selectively open and close the external gas supply flow path 1171a and the first circulation flow path 1130c connected to the cloth drying unit 1170.

[0492] In detail, the first flow path switching valve 1130d can separate the first circulation flow path 1130c from the cloth drying section 1170 and connect the external gas supply flow path 1171a to the cloth drying section 1170. In this way, heated air can flow into the accommodating space S to dry the cloth 242 of the sweeping robot 200.

[0493] In addition, the first flow path switching valve 1130d can separate the external gas supply flow path 1171a from the cloth drying section 1170, and connect the first circulation flow path 1130c to the cloth drying section 1170. In this way, heated air can flow to the dust collection section cover 1141 to sterilize the internal space of the dust collection section cover 1141.

[0494] On the other hand, the robot vacuum cleaner base station 1100 of the second embodiment of the present invention may include a dust bag drawer 144 and a dust bag (not shown).

[0495] The dust bag drawer 144 can be extended and attached to the front of the dust collection unit cover 1141. The dust bag drawer 144 can hold dust bags (not shown). Air heated by the cloth drying unit 1170 flows into the dust bag drawer 144 through the first circulation path 1130c. The air circulates within the dust bag drawer 144 containing the dust bags (not shown) before being exhausted to the outside. This achieves sterilization of the dust bags (not shown).

[0496] On the other hand, the conditions for ending the drying of the cloth 242 are explained in detail.

[0497] As an example, the first flow path switching valve 1130d can be operated by the control unit 300 after a preset time has elapsed since the start of drying the cloth 242. Specifically, the first flow path switching valve 1130d can be operated by the control unit 300 10 minutes after the start of drying the cloth 242. At this time, the drying of the cloth 242 is interrupted, and sterilization of the dust collection unit cover 1141 begins.

[0498] As another example, when the moisture content measured by sensor 290 is below a preset reference value, the first flow path switching valve 1130d can be operated by control unit 300.

[0499] In this regard, the robot vacuum cleaner base station 1100 of the second embodiment of the present invention may also include a sensor 290.

[0500] Sensor 290 can measure the moisture content of a mop cloth. Sensor 290 can be configured on the rotating plate 241 of the robotic vacuum cleaner 200. In this case, sensor 290 can transmit the moisture content information of the mop cloth to the robotic vacuum cleaner base station 1100. Alternatively, sensor 290 can be configured on the washing plate 122 of the robotic vacuum cleaner base station 1100. When the robotic vacuum cleaner 200 is attached to the robotic vacuum cleaner base station 1100, sensor 290 can contact at least a portion of the mop cloth to measure its moisture content. Sensor 290 can send the measured moisture content information to the control unit 300. Sensor 290 can also measure the moisture content of the mop cloth 242 during the drying process.

[0501] If the moisture content measured by sensor 290 is below a preset reference value, control unit 300 can operate the first flow path switching valve 1130d to separate the cloth drying unit 1170 from the external gas supply flow path 1171a, and connect the cloth drying unit 1170 to the first circulation flow path 1130c. At this time, the drying of cloth 242 is interrupted, and sterilization of dust collection unit cover 1141 can begin.

[0502] On the other hand, the robot vacuum cleaner base station 1100 of the second embodiment of the present invention may also include a temperature sensor 141f.

[0503] Temperature sensor 141f measures the temperature inside the dust collection chamber cover 1141. For example, temperature sensor 141f can be disposed inside the dust collection chamber cover 1141. Temperature sensor 141f can send the measured temperature information to control unit 300. When the temperature measured by temperature sensor 141f is above a preset reference value, control unit 300 can activate the first flow path switching valve 1130d. For example, when the temperature inside the dust collection chamber cover 1141 is above 55°C, the first flow path switching valve 1130d can separate the cloth drying section 1170 and the first circulation flow path 1130c, and connect the cloth drying section 1170 to the external gas supply flow path 1171a. This blocks the flow of air expelled into the dust collection chamber cover 1141, thus interrupting the sterilization process of the dust collection chamber cover 1141.

[0504] The following describes in detail the operation process of the first flow path switching valve 1130d in the robot vacuum cleaner base station 1100 of the second embodiment of this utility model.

[0505] First, with the robotic vacuum cleaner 200 integrated with the robotic vacuum cleaner base station 1100, the cloth drying unit 1170 is connected to the external gas supply path 1171a, but can be separated from the first circulation path 1130c. That is, the cloth drying unit 1170 can be connected to the receiving space S via the external gas supply path 1171a. Air heated by the cloth drying unit 1170 can flow along the external gas supply path 1171a into the receiving space S. The air flowing into the receiving space S can dry the robotic vacuum cleaner's cloth 242.

[0506] If a preset time has elapsed since the start of drying the cloth 242, the control unit 300 can activate the first flow path switching valve 1130d. For example, the first flow path switching valve 1130d can be set to activate 10 minutes after the start of drying the cloth 242. At this time, the first flow path switching valve 1130d can separate the cloth drying section 1170 from the external gas supply flow path 1171a and connect the cloth drying section 1170 to the first circulation flow path 1130c. Thus, the cloth drying section 1170 can communicate with the dust collection cover 1141 through the first circulation flow path 1130c. The air heated by the cloth drying section 1170 can flow into the dust collection cover 1141 along the first circulation flow path 1130c. With this configuration, sterilization of the dust collection cover 1141 can be performed.

[0507] As another example, when the moisture content of the cloth 242 measured by sensor 290 drops below a preset reference value, the control unit 300 can operate the first flow path switching valve 1130d. This enables the sterilization of the dust collection unit cover 1141.

[0508] On the other hand, if sterilization of the dust collection unit cover 1141 begins, the internal temperature of the dust collection unit cover 1141 will rise. The temperature sensor 141f can measure the internal temperature of the dust collection unit cover 1141.

[0509] As an example, when the temperature measured by the temperature sensor 141f is above 55°C, the first flow path switching valve 1130d can connect the cloth drying section 1170 to the external gas supply flow path 1171a and separate the cloth drying section 1170 from the first circulation flow path 1130c. This interrupts the sterilization process of the dust collection cover 1141. Conversely, when the temperature measured by the temperature sensor 141f is below 55°C, the cloth drying section 1170 can remain connected to the first circulation flow path 1130c.

[0510] As another example, if the temperature measured by temperature sensor 141f is above 55°C, the operation of heater 1171d can be stopped. This interrupts the sterilization process of the dust collection hood 1141. Conversely, if the temperature measured by temperature sensor 141f is below 55°C, heater 1171d can continue operating.

[0511] Third Embodiment

[0512] Figure 30a This is a diagram illustrating the external gas supply path and air exhaust path in the sweeping robot base station of the third embodiment of this utility model. Figure 30b This is a diagram illustrating the first and second circulation paths in the base station of the sweeping robot according to the third embodiment of this utility model.

[0513] Reference Figure 30a and Figure 30b This describes the robot vacuum cleaner base station 2100 of the third embodiment of this utility model.

[0514] To avoid repetition, except for the specially described components, the other components in this embodiment are the same as those of the robot vacuum cleaner base station in the second embodiment of this utility model in terms of structure and effect, and therefore can be referenced.

[0515] The dust collection cover 2141 of the robot vacuum cleaner base station 2100 in the third embodiment of this utility model may further include a hot air outlet 2141e. That is, the dust collection cover 2141 may include a hot air inlet 2141d and a hot air outlet 2141e.

[0516] A hot air inlet 2141d may be formed on the lower rear side of the dust collection unit cover 2141. The hot air inlet 2141d may be connected to the first circulation path 2130c. Air may flow into the dust collection unit cover 2141 through the hot air inlet 2141d via the first circulation path 2130c.

[0517] A hot air outlet 2141e may be formed on the upper rear side of the dust collection unit shroud 2141. Air flowing in from the hot air inlet 2141d can be discharged through the hot air outlet 2141e. The hot air outlet 2141e may be connected to the second circulation path 2172e, which will be described later. Air discharged to the hot air outlet 2141e may flow to the air discharge unit 2172 via the second circulation path 2172e.

[0518] As an example, on the rear side of the dust collection hood 2141, the hot air inlet 2141d can be located at the lower left end, and the hot air outlet 2141e can be located at the upper right end. On the rear side of the dust collection hood 2141, the hot air inlet 2141d and the hot air outlet 2141e can be positioned diagonally opposite each other. With this configuration, the air flowing into the dust collection hood 2141 can circulate internally along a left-right expanding path before being discharged to the outside of the dust collection hood 2141.

[0519] On the other hand, the air exhaust section 2172 of the robot vacuum cleaner base station 2100 in the third embodiment of the present invention may include an air exhaust flow path 2172c, a second circulation flow path 2172e, and a second flow path switching valve 2172f.

[0520] The air exhaust path 2172c allows air within the containment space S to be exhausted to the outside. At this time, one end of the air exhaust path 2172c can be connected to the containment space S, and the other end can be connected to the drain pipe 25. Specifically, the air intake 172a at one end of the air exhaust path 2172c can be connected to the containment space S, and the air outlet 172b at the other end can be connected to the drain pipe 25.

[0521] The second circulation path 2172e can connect the dust collection hood 2141 and the air exhaust 2172. Specifically, one end of the second circulation path 2172e can be connected to the dust collection hood 2141 via the hot air outlet 2141e, and the other end can be connected to the air exhaust 2172. Air inside the dust collection hood 2141 can flow to the air exhaust 2172 via the second circulation path 2172e. The air flowing to the air exhaust 2172 can merge with the air exhaust path 2172c and then be discharged to the outside. In other words, the second circulation path 2172e can discharge air from the dust collection hood 2141 to the outside.

[0522] The second flow path switching valve 2172f can be configured between the air exhaust section 2172 and the second circulation flow path 2172e. The second flow path switching valve 2172f can open and close the second circulation flow path 2172e connected to the air exhaust section 2172.

[0523] First, the state in which the second flow path switching valve 2172f connects the second circulation flow path 2172e to the air discharge section 2172 will be explained. At this time, the air circulating inside the dust collection section cover 2141 can be discharged to the outside through the second circulation flow path 2172e.

[0524] On the other hand, the second flow path switching valve 2172f can separate the second circulation flow path 2172e from the air discharge section 2172. At this time, the flow of air moving from the dust collection section cover 2141 to the air discharge section 2172 can be interrupted.

[0525] On the other hand, the robot vacuum cleaner base station 2100 of the third embodiment of the present invention may include a dust bag drawer 144 and a dust bag (not shown).

[0526] The dust bag drawer 144 can be extended and attached to the front of the dust collection unit cover 2141. The dust bag drawer 144 can hold a dust bag (not shown). Air heated by the cloth drying unit 2170 flows into the dust bag drawer 144 through the first circulation path 2130c. After circulating within the dust bag drawer 144 containing the dust bag (not shown), the air is discharged to the air exhaust unit 2172 through the second circulation path 2172e. This allows for the sterilization of the dust bag (not shown).

[0527] On the other hand, the conditions for ending the drying of the cloth 242 are explained in detail.

[0528] As an example, after a preset time has elapsed since the start of drying the cloth 242, the control unit 300 can operate the first flow path switching valve 2130d and the second flow path switching valve 2172f. Specifically, after 10 minutes since the start of drying the cloth 242, the control unit 300 can operate the first flow path switching valve 2130d and the second flow path switching valve 2172f. At this time, the drying of the cloth 242 is interrupted, and sterilization of the dust collection unit cover 2141 can begin.

[0529] As another example, when the moisture content measured by sensor 290 is below a preset reference value, control unit 300 can operate the first flow path switching valve 2130d and the second flow path switching valve 2172f.

[0530] In this regard, the robot vacuum cleaner base station 2100 of the third embodiment of the present invention may also include a sensor 290.

[0531] Specifically, sensor 290 can send the measured moisture content information to control unit 300. If the moisture content measured by sensor 290 is below a preset reference value, control unit 300 can activate the first flow path switching valve 2130d to connect the cloth drying unit 2170 with the first circulation flow path 2130c. Additionally, under the same conditions, control unit 300 can activate the second flow path switching valve 2172f to connect the air exhaust unit 2172 with the second circulation flow path 2172e. As a result, the drying of the cloth 242 is interrupted, and sterilization of the dust collection unit cover 2141 can begin.

[0532] According to the third embodiment of this utility model, the operation process of the first flow path switching valve 2130d and the second flow path switching valve 2172f is described in detail.

[0533] If the drying process of the cleaning cloth 242 begins, the moisture content of the cleaning cloth 242 decreases, and the sensor 290 can measure the moisture content of the cleaning cloth 242. The sensor 290 can transmit the moisture content information to the robot vacuum cleaner base station 2100. The sensor 290 can also send the measured moisture content information to the control unit 300. Based on the received information, the control unit 300 can control the operation of the first flow path switching valve 2130d and the second flow path switching valve 2172f.

[0534] When the moisture content of the cloth 242 drops below 1%, the control unit 300 can operate the first flow path switching valve and the second flow path switching valve 2172f. The first flow path switching valve 2130d can connect the dust collection sterilization module 2130 to the first circulation flow path 2130c. At the same time, the second flow path switching valve 2172f can connect the air exhaust section 2172 to the second circulation flow path 2172e. Thus, the dust collection sterilization module 2130 can communicate with the dust collection cover 2141 through the first circulation flow path 2130c, and the dust collection cover 2141 can communicate with the air exhaust section 2172 through the second circulation flow path 2172e. The air heated by the dust collection sterilization module 2130 can flow towards the dust collection cover 2141 along the first circulation flow path 2130c. The air circulating inside the dust collection cover 2141 can flow towards the air exhaust section 2172 along the second circulation flow path 2172e. Based on this configuration, sterilization of the dust collection unit cover 2141 can be performed.

[0535] After a preset time has elapsed since the start of sterilization of the dust collection unit cover 2141, the control unit 300 can operate the first flow path switching valve 2130d and the second flow path switching valve 2172f. For example, after 10 minutes from the start of operation of the first flow path switching valve 2130d and the second flow path switching valve 2172f, the control unit 300 can operate the first flow path switching valve 2130d and the second flow path switching valve 2172f again. At this time, the first flow path switching valve 2130d can separate the dust collection unit sterilization module 2130 from the first circulation flow path 2130c and connect the dust collection unit sterilization module 2130 to the external gas supply flow path 2171a. The second flow path switching valve 2172f can separate the air exhaust unit 2172 from the second circulation flow path 2172e. Thus, the sterilization of the dust collection unit cover 2141 can be interrupted.

[0536] As another example, the robot vacuum cleaner base station 2100 of the third embodiment of this utility model may also include a temperature sensor 141f.

[0537] When the temperature of the dust collection unit cover 2141 measured by the temperature sensor 141f is above a preset reference value, the control unit 300 can operate the first flow path switching valve 2130d and the second flow path switching valve 2172f. At this time, the first flow path switching valve 2130d can separate the dust collection unit sterilization module 2130 from the first circulation flow path 2130c and connect the dust collection unit sterilization module 2130 to the external gas supply flow path 2171a. Under the same conditions, the second flow path switching valve 2172f can separate the air exhaust unit 2172 from the second circulation flow path 2172e. As a result, the sterilization of the dust collection unit cover 2141 can be interrupted.

[0538] Fourth embodiment

[0539] Figure 31 This is a diagram illustrating the dust collection and sterilization module in the base station of the sweeping robot according to the fourth embodiment of this utility model.

[0540] Reference Figure 31 The following is a description of the dust collection and sterilization module 3130 of the sweeping robot base station 3100 of the fourth embodiment of this utility model.

[0541] On the other hand, except for the configuration specifically described, the configuration of the robot vacuum cleaner base station 3100 in the fourth embodiment of the present invention is the same as that of the robot vacuum cleaner base station in the first embodiment of the present invention in terms of configuration and effect, and therefore can be cited.

[0542] More specifically, the dust collection and sterilization module 3130 of the fourth embodiment may include a light source (not shown). In addition, the dust collection cover 3141 may include a dust bag 3143, a dust bag drawer 144, and a transparent panel 3143a.

[0543] Conversely, the dust collection sterilization module 3130 may not include a circulating fan and heater. Additionally, the dust collection enclosure 3141 may not include a hot air inlet, a hot air outlet, and a temperature sensor.

[0544] A light source (not shown) can emit germicidal light. The light source (not shown) can be a UV-C LED. The light source (not shown) can be positioned on the upper rear side inside the dust collection unit cover 3141. The light source (not shown) can emit germicidal light into the dust collection unit cover 3141 from its upper rear side. This allows for sterilization of the interior of the dust collection unit cover 3141.

[0545] More specifically, the dust collection cover 3141 may have a dust bag drawer 144 internally extendable, and the dust bag drawer 144 can hold a dust bag 3143. That is, the dust collection cover 3141 can house the dust bag 3143 internally. The dust bag 3143 can collect dust flowing in from the robot vacuum cleaner 200. The through panel 3143a can be configured to transmit the sterilizing light into the dust bag 3143. The through panel 3143a can be disposed on the upper side of the dust bag 3143. With the dust bag 3143 housed inside the dust collection cover 3141, the through panel 3143a can be disposed facing the light source (not shown). Thus, the sterilizing light from the light source (not shown) can be transmitted through the through panel 3143a and irradiate into the dust bag 3143. In this way, the interior of the dust bag 3143 can be sterilized.

[0546] Control methods

[0547] on the other hand, Figure 32 This is a block diagram illustrating the control configuration of the robot vacuum cleaner base station in the second embodiment of this utility model. Figure 33 This is a block diagram illustrating the control configuration of the robot vacuum cleaner base station according to the third embodiment of this utility model. Figure 34 This is a flowchart illustrating the control method of the sweeping robot according to the second embodiment of the present invention.

[0548] The control method of the sweeping robot base station in the second embodiment of this utility model may include a cloth drying step S10, a flow path conversion step S20, and a dust collection part sterilization step S30.

[0549] In the cloth drying step S10, hot air is expelled into the receiving space S to dry the cloth 242 of the robot vacuum cleaner 200. Specifically, if the control unit 300 receives a signal that the cloth 242 has finished washing, it can activate the heater 1171d and the circulating fan 1173 of the cloth drying unit 1170. The air heated by the heater 1171d can be expelled into the receiving space S by the circulating fan 1173. Thus, the cloth 242 of the robot vacuum cleaner 200 can be dried.

[0550] Meanwhile, sensor 290 can measure the moisture content of the cloth 242. The measured moisture content information can be sent to control unit 300.

[0551] Therefore, in the cloth drying step S10, the control unit 300 can determine whether to end the drying of the cloth 242 based on the moisture content measured by the sensor 290.

[0552] More specifically, in the cloth drying step S10, the moisture content of the cloth 242 is measured. The control unit 300 can receive moisture content information from the sensor 290. The control unit 300 can proceed to the next step if the measured moisture content is lower than a preset reference value. For example, the control unit 300 can proceed to the next step if the received moisture content is lower than 1%.

[0553] Conversely, if the measured moisture content is above a preset reference value, the control unit 300 can continue to execute the cloth drying step S10.

[0554] In the flow path switching step S20, the control unit 300 can operate the first flow path switching valve 1130d. At this time, the first flow path switching valve 1130d can separate the cloth drying unit 1170 from the external gas supply flow path 1171a and connect the cloth drying unit 1170 to the first circulation flow path 1130c. As a result, the flow of air into the accommodating space S can be interrupted, ending the drying of the cloth 242. On the other hand, in the flow path switching step S20, the control unit 300 can keep the heater 1171d and the circulating fan 1173 running. In this case, the first flow path switching valve 1130d can operate during continuous air flow to change the air flow.

[0555] As another example, the control unit 300 can first stop the operation of the heater 1171d and the circulating fan 1173, and then operate the first flow path switching valve 1130d to separate the cloth drying unit 1170 from the external gas supply flow path 1171a. Then, after the cloth drying unit 1170 is connected to the first circulation flow path 1130c, the control unit 300 can restart the operation of the heater 1171d and the circulating fan 1173.

[0556] In the dust collection unit sterilization step S30, the interior can be sterilized by expelling hot air into the dust collection unit cover 1141. More specifically, in the dust collection unit sterilization step S30, the cloth drying unit 1170 and the first circulation path 1130c can be connected. Air heated by the heater 1171d can be expelled into the dust collection unit cover 1141 along the first circulation path 1130c. Thus, sterilization of the interior of the dust collection unit cover 1141 can be achieved. In addition, the internal temperature of the dust collection unit cover 1141 may rise.

[0557] In the dust collection section sterilization step S30, the sterilization of the dust collection section cover 1141 can be terminated according to the conditions.

[0558] As an example, when the control unit 300 receives a signal that the internal temperature of the dust collection hood 1141 measured by the temperature sensor 141f is above a reference value, it can activate the first flow path switching valve 1130d to block the air being discharged into the dust collection hood 1141. Alternatively, under the same conditions, the control unit 300 can interrupt the operation of the heater 1171d to end the sterilization of the dust collection hood 1141.

[0559] As another example, after a predetermined time has elapsed since the start of the flow path switching step S20, the control unit 300 can operate the first flow path switching valve 1130d to block the air being discharged into the dust collection hood 1141. Alternatively, the control unit 300 can interrupt the operation of the heater 1171d under the same conditions to end the sterilization of the dust collection hood 1141.

[0560] In the dust collection sterilization step S30, the control unit 300 can keep the heater 1171d and the circulating fan 1173 running. In this case, the first flow path switching valve 1130d can operate during the continuous airflow to change the airflow.

[0561] As another example, after stopping the operation of the heater 1171d and the circulating fan 1173, the control unit 300 can operate the first flow path switching valve 1130d to separate the cloth drying unit 1170 from the first circulating flow path 1130c. Then, after the cloth drying unit 1170 is connected to the external gas supply flow path 1171a, the control unit 300 can restart the operation of the heater 1171d and the circulating fan 1173.

[0562] The control method of the robot vacuum cleaner base station according to the third embodiment of this utility model is described. The control method of the robot vacuum cleaner base station may include a cloth drying step S10, a flow path conversion step S20, and a dust collection part sterilization step S30.

[0563] To avoid repetition, except for the specially described components, the other contents in this embodiment are the same as the control method of the robot vacuum cleaner base station in the second embodiment of this utility model, and therefore can be cited.

[0564] In the flow path switching step S20, the control unit 300 can operate the first flow path switching valve 2130d and the second flow path switching valve 2172f.

[0565] At this time, the first flow path switching valve 2130d can separate the cloth drying section 2170 from the external gas supply flow path 2171a and connect the cloth drying section 2170 to the first circulation flow path 2130c. Additionally, the second flow path switching valve 2172f can connect the air discharge section 2172 to the second circulation flow path 2172e. Thus, the flow of air into the accommodating space S is interrupted, and the drying of the cloth 242 can be terminated.

[0566] In the dust collection unit sterilization step S30, the interior can be sterilized by expelling hot air into the dust collection unit cover 2141. More specifically, in the dust collection unit sterilization step S30, the cloth drying unit 2170 and the first circulation path 2130c can be connected, and the air exhaust unit 2172 and the second circulation path 2172e can be connected. The air heated by the heater 2171d can be expelled into the dust collection unit cover 2141 along the first circulation path 2130c. The air circulating inside the dust collection unit cover 2141 can flow towards the air exhaust unit 2172 along the second circulation path 2172e. Thus, the interior of the dust collection unit cover 2141 can be sterilized.

[0567] In the dust collection section sterilization step S30, the sterilization of the dust collection section cover 2141 can be terminated according to the conditions.

[0568] As an example, when the control unit 300 receives a signal indicating that the internal temperature of the dust collection hood 2141 measured by the temperature sensor 141f is above a reference value, it can activate the first flow path switching valve 2130d to block the air being discharged into the dust collection hood 2141, and activate the second flow path switching valve 2172f to separate the air discharge section 2172 from the second circulation flow path 2172e. Alternatively, the control unit 300 can interrupt the operation of the heater 2171d under the same conditions to end the sterilization of the dust collection hood 2141.

[0569] As another example, after a predetermined time has elapsed since the start of the flow path switching step S20, the control unit 300 can operate the first flow path switching valve 2130d to block the air discharge to the dust collection hood 2141, and can operate the second flow path switching valve 2172f to separate the air discharge section 2172 from the second circulation flow path 2172e. Alternatively, under the same conditions, the control unit 300 can interrupt the operation of the heater 2171d to end the sterilization of the dust collection hood 2141.

[0570] Although the present invention has been described in detail above through specific embodiments, this is only for the purpose of illustrating the present invention. The present invention is not limited thereto. It should be understood that those skilled in the art can make modifications or improvements to the present invention within the scope of its technical concept.
