Description

Technical Field

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

[0002] Recently, with the development of industrial technology, a robotic vacuum cleaner has been developed that can move and clean the area that needs cleaning without user intervention.

[0003] Such a robot vacuum cleaner is equipped with sensors that can identify the space to be cleaned, an agitator that can sweep and clean the floor, and a mop that can wipe the floor. It can suck up dust from the floor in the space identified by the sensors and move while wiping with the mop.

[0004] Robotic vacuum cleaners come in two types: dry-type, which sucks up and removes debris scattered on the floor; and wet-type, which uses a damp cloth to wipe the floor for effective removal of debris. Dry-type vacuum cleaners have a dustbin and use a suction motor to suck up debris from the floor. Wet-type vacuum cleaners are configured with a water tank; the water in the tank is supplied to a damp cloth, which then wipes the floor to effectively remove debris. Additionally, there are robotic vacuum cleaners that combine an agitator and a cloth.

[0005] The charging dock for a robotic vacuum cleaner is a device that allows the robot to dock after cleaning and supplies power to its battery for charging. 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, power is supplied to the battery for charging.

[0006] On the other hand, when the charging dock for a robotic vacuum cleaner is placed indoors, it will occupy a certain amount of indoor space. In this case, the space efficiency of the room may decrease. In addition, if a user or pet collides with the robotic vacuum cleaner while passing by, not only may the user or pet be injured, but the robotic vacuum cleaner may also be damaged.

[0007] In addition, when a base station is equipped with a dust collection function for a robotic vacuum cleaner, there is a limitation that as the volume it occupies increases, it may damage the interior decoration.

[0008] On the other hand, Chinese utility model authorization announcement CN218922468U discloses a base station for a sweeping machine that is integrated with the lower side of a washing machine to charge the sweeping robot, collect dust, and clean the wet cloth of the sweeping robot.

[0009] However, the cleaning robot base station has an open space below the washing machine that the cleaning robot can enter. On the vertical upper side of the space for the cleaning robot to enter, there is a detergent and water supply device for washing wet cloths, and a dust bag is arranged on the side of the space for the cleaning robot to enter.

[0010] With this configuration, the overall height of the cleaning machine base station increases, which limits the ability to effectively utilize the space under furniture, including the sink, for installation.

[0011] In addition, since the cleaning machine base station needs to be installed below the washing machine, there are the following limitations: space must be configured to install the washing machine, taking into account the height of the washing machine itself and the height of the cleaning machine base station, requiring a configuration space that exceeds their height.

[0012] On the other hand, the cleaning machine base station collects the dust from the dust canister of the vacuum cleaner into a dust bag located on the side, and then discharges it into the space behind the cleaning machine base station.

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

[0014] In addition, because kitchen cabinets have water pipes, the surrounding humidity may be high. On the other hand, the outer frame may be enclosed by baseboards or other structures.

[0015] In such a situation, with the air exhausted from the dust collection motor being discharged into the lower space of the kitchen cabinets, there is a limitation that dust may scatter and potentially spread into the room.

[0016] At the same time, the air heated by the dust collection motor fills the lower part of the kitchen cabinets, which may cause the temperature to rise in the lower part of the kitchen cabinets, making the space under the kitchen cabinets hot and humid and potentially causing pollution. Utility Model Content

[0017] The problem to be solved

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

[0019] In addition, its 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.

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

[0021] In addition, its purpose is to provide a robot vacuum cleaner base station that can achieve a compact overall size by configuring the flow path required for dust collection within a limited height and lateral space.

[0022] In addition, its purpose is to provide a robot vacuum base station that allows hot air exhaled from the dust collection motor to be drawn into the suction unit of the robot vacuum, so that hot air does not enter the interior of the kitchen cabinet, thereby preventing damage to the interior of the kitchen cabinet.

[0023] In addition, its purpose is to provide a robotic vacuum cleaner base station that can effectively utilize the maximum capacity of the dust bag used in a limited space.

[0024] Technical solutions to the problem

[0025] To achieve the above-described objectives, the present invention provides a robotic vacuum cleaner base station comprising: a cover; a mounting portion disposed on the cover, wherein at least a portion of the robotic vacuum cleaner is attached to the mounting portion; and a dust collection portion for collecting dust from inside the dust bin of the robotic vacuum cleaner, the dust collection portion comprising: a dust collection portion cover, wherein dust from the dust bin flows into the dust collection portion cover; a dust bag drawer detachably attached to the dust collection portion cover; a dust bag detachably attached to the dust bag drawer for collecting dust flowing from the dust bin; and a dust collection motor for providing suction to draw dust from the dust bin.

[0026] At this time, the dust bag drawer forms a flow path, which discharges the air passing through the dust bag to the dust collection motor.

[0027] Specifically, the dust bag drawer may include: a dust bag drawer body; and a flow path separation section, which protrudes upward from the bottom surface of the dust bag drawer body, forming a flow path between the flow path separation section and the dust collection cover.

[0028] At this time, the flow path separation section may include a flow path separation sidewall, which is formed by bending upward from the bottom surface of the dust bag drawer body.

[0029] In addition, the flow path separation section may include a flow path separation cover wall, which is connected to the flow path separation side wall and forms a step with the bottom surface of the dust bag drawer body.

[0030] At this time, the flow path separation section can be formed along the length direction of the dust bag drawer.

[0031] Therefore, the flow path for discharging air through the dust bag to the dust collection motor can be formed in a space surrounded by the flow path separation sidewall, the upper side of the wall flow path, and the bottom surface of the dust collection unit cover.

[0032] On the other hand, the dust bag drawer includes: an inlet formed in the dust bag drawer body for air to flow into the dust bucket; and an outlet for air to be discharged from the inlet, the outlet being formed at one end of the flow path separation section along its length.

[0033] In addition, the other end of the flow path separation section along its length can be connected to the rear side of the dust bag drawer body on which the flow inlet is formed.

[0034] Therefore, the air flowing into the outlet can flow rearward along the length of the flow path separator and be discharged.

[0035] On the other hand, the outlet can be configured to be lower than the inlet with the bottom surface of the dust bag drawer body as a reference.

[0036] In addition, the outlet can be configured in a position forward of the inlet.

[0037] Therefore, the air flowing in from the upper rear side of the dust bag drawer flows towards the lower front side of the dust bag drawer while passing through the dust bag, so that the dust-containing air can be evenly diffused inside the dust bag, preventing dust from accumulating in specific locations within the dust bag.

[0038] On the other hand, the dust bag drawer may also include a handle, which is disposed on the dust bag drawer body and configured to be gripped by a user.

[0039] At this time, the outlet can be configured to be closer to the handle than the inlet.

[0040] On the other hand, the dust bag drawer may also include a gasket that provides an airtight seal between the dust bag drawer and the dust collection unit cover.

[0041] On the other hand, the dust bag drawer may also include a handle, which is disposed on the dust bag drawer body and configured to be gripped by a user.

[0042] On the other hand, the dust bag drawer may include a gasket that provides an airtight seal between the dust bag drawer and the dust collection unit cover.

[0043] On the other hand, the flow path separation section may include a flow path separation cover wall, which is connected to the flow path separation side wall and forms a step with the bottom surface of the dust bag drawer body.

[0044] Utility Model Effect

[0045] As described above, the robot vacuum cleaner base station of this utility model is equipped with a module that can charge the robot vacuum cleaner, collect dust, and clean the mop along the horizontal direction of the robot vacuum cleaner, thereby effectively utilizing the space under the kitchen cabinet.

[0046] In addition, the charging terminal, dust collection unit, mop cleaning unit, and mop drying unit are arranged in a configuration centered around the robot vacuum cleaner, thus enabling the robot vacuum cleaner to perform various functions simultaneously.

[0047] In addition, since the other sides are covered by kitchen cabinets, it can provide an aesthetic effect for users in terms of decoration.

[0048] In addition, when the robot vacuum is in use, it automatically collects dust from the dustbin inside, so users only need to pull out the dust bag at regular intervals, which reduces the hassle for users.

[0049] In addition, the flow paths required for dust collection are stacked within a limited height and lateral space, and the dust collection motor is arranged vertically to utilize the stacked flow paths to allow air to flow in and out, thereby maximizing space efficiency.

[0050] In addition, the dust collection motor is arranged vertically and a shock absorber is installed at its lower part, which has the effect of reducing the generation of vibration and noise.

[0051] In addition, since the cover components can be assembled from the top and bottom of the dust collection motor, it is easy to assemble and repair.

[0052] In addition, by keeping the inlet and outlet of the air passing through the dust bag far apart, dust is prevented from accumulating in specific parts of the dust bag, thus achieving the effect of effectively utilizing the maximum capacity of the dust bag. Attached Figure Description

[0113] Furthermore, the following embodiments are provided to enable those skilled in the art to understand more fully, and for the purpose of clearer explanation, the shapes and sizes of the constituent elements in the drawings may be exaggerated.

[0114] Kitchen cabinets and sweeping systems

[0115] Figure 1 The diagram illustrates a cleaning system of an embodiment of the present invention positioned under a kitchen cabinet. Figure 2 The diagram illustrates the relationship between the piping of the sweeper system and the drain pipe in an embodiment of the present invention.

[0116] The cleaning system 1 of this utility model 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 tableware.

[0117] In addition, kitchen cabinet 2 can be equipped with a sink or cooking counter or a top panel (workbench) that can serve as a work surface.

[0118] For example, kitchen cabinet 2 may include a sink that provides space on the top panel for washing dishes. Alternatively, kitchen cabinet 2 may include a cooking countertop for cooking operations. Additionally, kitchen cabinet 2 may include a gas stovetop with a gas cooktop, induction cooker, pressure cooker, or oven mounted on the top panel.

[0119] 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.

[0120] In another embodiment of this utility model, the sweeper system 1 can be installed on the underside of a structure including at least one of a water supply pipe and a drain pipe. Specifically, the water supply pipe can refer to a flow path connected to an external water source supplying fluid to the structure, and the drain pipe can refer to a flow path discharging fluid discharged from the structure into a sewer.

[0121] A storage cabinet for storing tableware and kitchen tools can be installed at the lower part of such a kitchen cabinet 2 or the structure. That is, the kitchen cabinet 2 or the structure may include: a top panel 22 providing space for cooking or washing tableware; a lower side panel 23 configured to be at a predetermined height above the ground; and storage space formed between the top panel 22 and the lower side panel 23 for storing tableware and kitchen tools. In the case where the kitchen cabinet 2 is a sink, a dishwashing platform 22a can be installed on the top panel 22.

[0122] Additionally, the lower side panel 23 can be supported by legs 21. Legs 21 are positioned perpendicular to the kitchen floor and can support the load of the kitchen cabinet 2. At this time, depending on the height of the legs 21, a space can be formed between the kitchen floor and the lower side panel 23.

[0123] In contrast, kitchen cabinet 2 can be fixed to the wall of the building without the support legs 21. In this case, a space can also be formed between the kitchen floor and the lower side panel 23.

[0124] The cleaning system 1 of this utility model is installed as described above in the space between the kitchen floor and the lower side panel 23 (hereinafter, it may also be referred to as the installation space).

[0125] For example, the installation space can be less than 200mm in height, and typically less than 160mm in height.

[0126] Therefore, according to this utility model, since the cleaning system 1 is configured in the lower space of the kitchen cabinet 2, it has the effect of minimizing the exposure of the cleaning system 1 to the outside.

[0127] In addition, compared to configuring a charging dock for a robot vacuum cleaner in a certain space in the living room, bedroom or kitchen, the robot vacuum system 1 does not occupy a separate space and can be configured in the unused space provided by the kitchen cabinet 2, thus maximizing space efficiency.

[0128] On the other hand, a drain pipe 25 is provided in the kitchen cabinet 2 or the structure therein to drain liquids used in cooking or water used in washing dishes. At least a portion of the drain pipe 25 may be configured in the storage space formed between the top panel 22 and the lower side panel 23. Typically, the drain pipe 25 may be connected to the drain outlet of the sink 22a formed in the sink. The drain pipe 25 includes a U-trap 25a to prevent backflow of contaminated gases or odors. The U-trap 25a may be configured in the storage space. Liquid flowing in through the drain outlet may flow downwards due to gravity at the upstream 25b of the U-trap, accumulate in the U-trap 25a, and, if the water overflows above a predetermined water level due to the U-trap 25a, flow downwards along the downstream 25c of the U-trap and be discharged into the sewer.

[0129] The sweeper system 1 of this utility model can use the drain pipe 25 as described above to wash and dry the rag 242 of the sweeping robot 200.

[0130] Additionally, although not shown in the diagram, kitchen cabinet 2 may be equipped with a water supply pipe. Tap water (or purified water) can be supplied to the cleaning system 1 through the water supply pipe.

[0131] The specific structure of the sweeper system 1 will be described below.

[0132] Sweeping system

[0133] On the other hand, Figures 3 to 5 The figure shows a sweeper system used to illustrate an embodiment of the present invention.

[0134] The cleaning system 1 of the embodiments of this specification may include a sweeping robot base station 100 and a sweeping robot 200.

[0135] The cleaning system 1 includes a robot vacuum base station 100. A robot vacuum 200 can be integrated into the robot vacuum base station 100. Specifically, the robot vacuum 200 can enter the front of the robot vacuum base station 100 and can be housed inside the robot vacuum base station 100. The robot vacuum base station 100 can remove dust from the dustbin 220 of the robot vacuum 200. The robot vacuum base station 100 can clean the rotating cleaning section 240 of the robot vacuum 200. The robot vacuum base station 100 can dry the rotating cleaning section 240 of the robot vacuum 200. The robot vacuum base station 100 can supply power to the robot vacuum 200.

[0136] robot vacuum cleaner

[0137] On the other hand, Figures 6 to 9The present invention discloses a drawing of a sweeping robot system for illustrating embodiments of the present invention.

[0138] Reference Figures 6 to 9 The structure of the robotic vacuum cleaner 200 is described below.

[0139] The 200 robotic vacuum cleaner automatically cleans the area by sucking up dust and other debris from the floor while driving itself through the area it wants to clean.

[0140] The sweeping robot 200 of this embodiment is configured to be placed on the floor and sweep the floor while moving along the floor surface. Therefore, the following description will be based on the state of the sweeping robot 200 placed on the floor to determine the vertical direction.

[0141] 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.

[0142] The “lowest part” of each structure described in the embodiments of this utility model may be the part located at the lowest position in each structure when the robot vacuum cleaner 200 of this utility model is placed on the floor and used, or it may be the part closest to the floor.

[0143] The sweeping robot 200 of this utility model is configured to include 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.

[0144] The main body 210 can form the overall shape of the robotic vacuum cleaner 200. Various components constituting the robotic vacuum cleaner 200 can be integrated into the main body 210, and some of the components constituting the robotic vacuum cleaner 200 can be housed inside the main body 210.

[0145] Specifically, the main body 210 can house the components of the robotic vacuum cleaner 200 within its internal space. For example, the main body 210 can accommodate a battery and at least one motor within its internal space.

[0146] In embodiments of this invention, the main body 210 can be configured such that its width (or diameter) in the horizontal direction (parallel to the X and Y axes) is greater than its height in the vertical direction (parallel to the Z axis). Such a main body 210 helps the robotic vacuum cleaner 200 form a stable structure and provides a structure that facilitates obstacle avoidance when the robotic vacuum cleaner 200 moves (drives).

[0147] When viewed from above or below, the main body 210 can be formed in various shapes such as a circle, an oval, or a quadrilateral.

[0148] The main body 210 can be divided into a lower main body and an upper main body, and the lower main body and the upper main body can be combined to form a space inside.

[0149] 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.

[0150] The lower body may have an intake section 211 for air to flow in and a hole for accommodating a pair of wheels 260.

[0151] The suction section 211 can be a channel for dust from the floor to flow into. Furthermore, the suction section 211 can communicate with a suction flow path (not shown) formed inside the main body 210, and the suction flow path can communicate with the internal space of the dust bin 220.

[0152] 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. At this time, a filter can be installed at the exhaust port.

[0153] With this configuration, the air flowing in through the suction section 211 can flow into the dust bin 220 through the suction flow path and be discharged to the exhaust port through the exhaust flow path.

[0154] The agitator 250, which will be described later, can be rotatably housed in the suction section 211. With this configuration, dust around the suction section 211 can be guided into the suction section 211 by the rotation of the agitator 250, and the efficiency of dust suction can be increased.

[0155] The upper body can form the upper appearance of the robotic vacuum cleaner 200. Although not shown, the upper body may be equipped with a display.

[0156] The robotic vacuum cleaner 200 of this invention may include a bumper. The bumper is configured to be attached along the edge of the body 210 and movable relative to the body 210.

[0157] The bumper can be partially or entirely attached to the edge of the body 210. At least one elastic member (not shown) can be provided between the bumper and the body 210. With this configuration, when the bumper contacts an obstacle or the like and moves relative to the center of the body 210, the bumper can return to its original position via the restoring force of the elastic member (not shown), thus preventing and reducing the transmission of impact to the body 210 by absorbing or dispersing the impact applied to the bumper.

[0158] The dust bin 220 can be configured to suck in external dust and air and store the dust.

[0159] The dust bin 220 is capable of storing dust that flows in through the suction flow path. The dust bin 220 may have a dust inlet communicating with the suction flow path, an internal space capable of storing dust, and an air outlet capable of discharging air.

[0160] 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.

[0161] On the other hand, in this invention, a dust discharge path can be formed in the dust bin 220. This dust discharge path connects the internal space of the dust bin 220 with the external space of the robotic vacuum cleaner 200. With this configuration, while the robotic vacuum cleaner base station 100 collects dust, it is possible to remove dust from inside the dust bin 220.

[0162] On the other hand, in embodiments of the present invention, the dust bin 220 may have a dust outlet 221 communicating 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.

[0163] Furthermore, the robotic vacuum cleaner 200 in this embodiment of the present invention may be equipped with a dust bin door 222 capable of selectively opening and closing the dust outlet 221. Specifically, the dust bin door 222 may be attached to the main body 210 and positioned to block the dust outlet 221. As an example, the dust bin door 222 is formed of rubber or resin material, is rotatable, and one side may be fixedly attached to the main body 210.

[0164] With this configuration, when the dust collection motor 145 of the robot vacuum base station 100 (described later) is activated, the dust bin door 222 is elastically deformed by the driving force of the dust collection motor 145. At the same time as the dust discharge port 221 opens, the dust in the dust bin 220 can be collected into the dust collection section 140 of the robot vacuum base station 100.

[0165] The bucket 230 is configured as a container with an internal space for storing liquids such as water. The bucket 230 is disposed inside the main body 210 and can be fixedly attached to the main body 210, or can be detachably attached to the main body 210.

[0166] 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 has an inlet formed on the other side behind the outer side (or outer peripheral surface) of the main body 210, and can be connected to the storage space inside the water tank 230 via a water supply hose.

[0167] In this case, considering its relationship with the dust outlet 221, the supply unit 231 can be positioned on opposite sides of the sweeping robot 200 in the left-right direction. For example, if the dust outlet 221 is positioned on the rear left side of the main body 210, then the supply unit 231 can be positioned on the rear right side of the main body 210.

[0168] With this configuration, when the robot vacuum cleaner 200 and the robot vacuum cleaner base station 100 are combined, the robot vacuum cleaner base station 100 can simultaneously perform dust collection and water injection.

[0169] On the other hand, the nozzle (not shown) is in the form of a tube or conduit and is connected to the water tank 230 to allow the liquid inside the water tank 230 to flow through it. The nozzle (not shown) is configured such that one side is connected to the water tank 230 and the other end is located on the upper side of a pair of rotating plates 241 or on the rotating plates, thereby enabling the liquid inside the water tank 230 to be supplied to a pair of wiping cloths 242 respectively.

[0170] 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.

[0171] On the other hand, although not shown, a pump can be installed in the water tank 230 to allow water inside the water tank 230 to flow to the nozzle (not shown). Therefore, when the pump in the water tank 230 is activated, the liquid stored in the water tank 230 can be ejected through the nozzle (not shown) to the rotating cleaning unit 240.

[0172] The rotating cleaning unit 240 includes a rotating plate 241 and a cleaning cloth 242.

[0173] The rotating plate 241 may be provided with a pair of rotating plates including a left rotating plate and a right rotating plate, and the wiping cloth 242 may be provided with a pair of wiping cloths including a left wiping cloth and a right wiping cloth.

[0174] The rotating plate 241 can be rotatably disposed on the bottom surface of the main body 210, and the rag 242 can be attached to the lower side.

[0175] The rotating plate 241 is configured with a specified area and is composed of a flat plate or a flat frame. This rotating plate 241 is typically laid horizontally, thus forming a shape where the width (or diameter) in the horizontal direction is sufficiently larger than the height in the vertical direction. The rotating plate 241, attached to the main body 210, can be parallel to the floor surface B or inclined to it. The rotating plate 241 can be formed into a circular plate shape, the bottom surface of which can be approximately circular, and the rotating plate 241 can form a rotationally symmetrical shape overall.

[0176] A pair of rotating plates 241 can be configured symmetrically on the left and right.

[0177] The rag 242 can be attached to the underside of the rotating plate 241 in a manner opposite to the floor surface B.

[0178] The rag 242 is configured such that its bottom surface facing the floor has a specified area, and the rag 242 is configured in a flat shape. The width (or diameter) of the rag 242 in the horizontal direction is sufficiently larger than its height in the vertical direction. When the rag 242 is attached to the side of the main body 210, the bottom surface of the rag 242 can be parallel to the floor surface B or inclined to the floor surface B.

[0179] The bottom surface of the cleaning cloth 242 is roughly circular, and the cleaning cloth 242 as a whole is rotationally symmetrical. In addition, the cleaning cloth 242 can be detached from 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.

[0180] On the other hand, although not shown, the rotary cleaning unit 240 may be provided with a drive unit that applies rotational force to the rotating plate 241. For example, the drive unit may be provided with a motor and at least one gear. Therefore, when the drive unit is activated, the rotating plate 241 and the mop 242 can rotate to wipe and clean the floor surface.

[0181] The agitator 250 is rotatably equipped with a plurality of brushes, thereby guiding external dust and air to the dust bin 220. The agitator 250 may also be equipped with at least one gear.

[0182] On the other hand, the agitator 250 of this embodiment can of course be equipped with another agitator motor (not shown) to transmit rotational power, or it can transmit rotational power from the drive motor according to the embodiment, or it can transmit rotational power from the drive unit of the rotating cleaning unit 240.

[0183] 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 combined with main body 210.

[0184] Wheel 260 is mounted on the main body 210 and can roll on the floor surface.

[0185] Wheel 260 can be composed of a first driving wheel and a second driving wheel. In this case, the first driving wheel can be configured 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 sweeping robot 200, then the second driving wheel can be located on the right side of the sweeping robot 200. In this case, the first driving wheel and the second driving wheel can be configured symmetrically to each other.

[0186] The drive unit (not shown) may consist of a drive motor and gears. In this case, the drive motor is housed inside the main body 210 and is capable of providing power to the wheel 260. The drive motor may include a first drive motor and a second drive motor.

[0187] The travel motor can be an electric motor. A plurality of gears are configured to mesh and rotate with each other, connecting the travel motor to the wheel 260 and 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.

[0188] With this configuration, when the driving motor is activated, the wheel 260 rotates, and the main body 210 can travel on the floor at a specified speed.

[0189] The auxiliary wheel 270 is located on the underside of the main body 210 and can roll on the floor surface (the surface to be cleaned). The auxiliary wheel 270, together with a pair of wheels 260, can support the main body 210 on the floor surface. With this configuration, the auxiliary wheel 270 can guide the movement of the robot vacuum cleaner 200 while minimizing friction between the robot vacuum cleaner 200 and the floor surface.

[0190] The suction motor (not shown) generates suction through the suction section 211 to draw in external dust and air. For example, the suction motor (not shown) can be an electric motor. Through 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.

[0191] Although not shown, the battery is configured to be integrated with the main body 210 and supply power to other components constituting the robotic vacuum cleaner 200. The battery is capable of supplying power to at least one or more motors provided in the robotic vacuum cleaner 200. For example, the battery is capable of supplying power to motors provided in the rotary cleaning unit 240, the agitator 250, the wheels 260, and the suction motor (not shown).

[0192] In addition, the battery can supply power to the sensor unit (not shown) and the control unit (not shown).

[0193] The battery can be charged using an external power source. 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 surface of the main body 210. When the robotic vacuum cleaner 200 is combined with the robotic vacuum cleaner base station 100, the charging terminal 280 can contact the power supply terminal 123b of the robotic vacuum cleaner base station 100 to receive power.

[0194] Robot vacuum cleaner base station

[0195] exist Figure 10 The figure shows a perspective view of a robot vacuum cleaner base station used to illustrate an embodiment of the present invention. Figure 11 The Chinese illustration shows Figure 10 Top view.

[0196] Reference Figure 10 and Figure 11 The sweeping robot base station 100 of this utility model is described as follows.

[0197] A robot vacuum cleaner 200 can be accommodated in a robot vacuum cleaner base station 100. A robot vacuum cleaner 200 can be integrated into the mounting section 120 of the robot vacuum cleaner base station 100.

[0198] The robot vacuum cleaner base station 100 may include a cover 110.

[0199] The cover 110 can form the appearance of the robot vacuum cleaner base station 100. As an example, the cover 110 can be formed into a shape similar to a hexahedron including at least one or more outer wall surfaces.

[0200] The cover 110 can form a space inside that can accommodate the placement part 120, the dust collection flow path 147, 148, the dust collection part 140, the dust collection motor 145, the cloth washing part 160, the cloth drying part 170, and the return flow path.

[0201] The cover 110 can be installed on the lower side 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.

[0202] The enclosure 110 includes a pair of outer walls 111 facing each other. The outer walls 111 may refer to surfaces formed along the direction of gravity.

[0203] As one example, a pair of outer walls 111 can be spaced apart at a predetermined interval and installed on the lower side of the kitchen cabinet 2. As another example, the cover 110 also includes a bottom surface opposite the kitchen floor, and the pair of outer walls can be connected through the bottom surface. As yet another example, the cover 110 also includes an upper side surface 113 opposite the bottom surface opposite the kitchen floor and the lower side panel 23 of the kitchen cabinet 2, and the upper and lower ends of the pair of outer walls 111 can be connected to each other through the bottom surface and the upper side surface 113. Therefore, even if foreign objects fall 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 side surface 112, and a rear side surface 111b opposite the wall of the building.

[0204] With this configuration, the components of the robot vacuum base station 100 can be accommodated inside the housing 110 (between one pair of outer walls).

[0205] Additionally, the robotic vacuum cleaner 200 can be accommodated inside the enclosure 110. The enclosure 110 can be configured such that the gap between its outer walls 111 is larger than the maximum horizontal width of the robotic vacuum cleaner 200. With this configuration, the robotic vacuum cleaner 200 can enter and exit the interior of the enclosure 110.

[0206] In this embodiment, the robotic vacuum cleaner 200 can enter and exit from the front of the robotic vacuum cleaner base station 100. Here, "front" can refer to the direction in which the door 126 is located, with the interior of the robotic vacuum cleaner base station 100 as a reference.

[0207] 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 installed behind the robotic vacuum cleaner base station 100.

[0208] In addition, based on the observation of the front from inside the robot vacuum cleaner base station 100, the left side can be referred to as the left side and the right side as the right side.

[0209] 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.

[0210] 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, the left and right sides of the cover 110 are covered by the outer wall and are positioned at the bottom of the kitchen cabinet 2. At this time, the lower part of the kitchen cabinet 2, except for the robot vacuum base station 100, is finished off by the baseboard 26, so ultimately only the front of the cover 110 can be exposed to the outside.

[0211] This minimizes the exposure of the robot vacuum base station 100 and the robot vacuum 200 to the outside.

[0212] With this configuration, the robot vacuum cleaner base station 100 of this utility model can bring aesthetic benefits to users in terms of decoration.

[0213] On the other hand, although not shown, the cover 110 may have spaces for a water supply hose connected to a water supply pipe to pass through, and spaces for a drainage hose to pass through for draining wastewater generated after washing the cloth 242. It may also have spaces for a hose to pass through for draining water generated during the drying process of the cloth 242. For example, spaces for the hoses to pass through may be formed in at least one of the outer wall 111 and the upper side 112 of the cover 110.

[0214] Joint

[0215] like Figure 11 As illustrated, the robot vacuum cleaner base station 100 may include a mounting unit 120.

[0216] The sweeping robot 200 and the sweeping robot base station 100 can be connected via the installation unit 120 via physical ground, electrical ground and / or flow path ground.

[0217] The mounting section 120 can be installed inside the cover 110.

[0218] At this time, according to the embodiment, the placement part 120 is configured to be able to be pulled out from the cover 110 using the drawer 190.

[0219] With this configuration, when the installation unit 120 needs cleaning or repair, or when some parts need to be replaced, the user can easily pull out the installation unit 120 for management.

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

[0221] 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 is greater than the height of the robot vacuum cleaner 200. In this case, the entrance / exit 127 can refer to the 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.

[0222] Furthermore, the entrance / exit 127 is configured such that its width in the left-right direction is greater than the maximum width of the sweeping robot 200. In this case, at least one of the dust collection section 140 and the mop cleaning section 160 can be arranged on the left and right sides of the entrance / exit 127. Therefore, the left and right ends of the entrance / exit 127 can form boundaries with the dust collection section 140 and the mop cleaning section 160. If either the dust collection section 140 or the mop cleaning section 160 is absent, the outer wall surface of the cover 110 can also serve as the boundary.

[0223] At this time, the entrance / exit 127 can be opened and closed using the door 126. The door 126 is located 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 portion 120.

[0224] Door 126 can be rotated using door drive unit 126a. As an example, door drive unit 126a can be a motor.

[0225] For example, the door 126 can be formed into a rectangular flat plate shape, with a hinge portion 126b at the upper end, 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 in a way that allows power transmission through at least one or more gears.

[0226] The door 126 can maintain the closed entrance / exit 127 state while the robotic vacuum cleaner 200 is housed in the mounting section 120. Furthermore, when the robotic vacuum cleaner 200 begins to move from the mounting section 120, the door 126 can rotate to open the entrance / exit 127. Also, the door 126 can rotate to close the entrance / exit 127 after the robotic vacuum cleaner 200 has passed through it. Additionally, when the robotic vacuum cleaner 200 approaches from outside the robotic vacuum cleaner base station 100, the door 126 can rotate to open the entrance / exit 127.

[0227] The placement part 120 may include a receiving space S, a base 121, a connecting wall 123, and an inner wall 124.

[0228] The receiving space S of the placement section 120 can accommodate the sweeping robot 200. As one example, the receiving space S can refer to the space surrounded by the base 121, the connecting wall 123, and the inner wall 124. As another example, the receiving space S can refer to the space surrounded by the base 121, the cleaning plate 122, the connecting wall 123, and the inner wall 124. As yet another example, the receiving space S can refer to the space where the sweeping robot 200 is located when it is connected to the power supply terminal 123b, or the space where the sweeping robot 200's dustbin 220 is connected to the dust passage 123a.

[0229] The base 121 can be configured to allow the robot vacuum base station 100 to contact the floor surface, providing support for the robot vacuum 200 when it is combined with the robot vacuum base station 100. The upper side of the base 121 can contact the wheels 260 of the robot vacuum 200. Additionally, the upper side of the base 121 can contact the auxiliary wheels 270 of the robot vacuum 200.

[0230] The base 121 may include a base body 121a, an inclined portion 121b, a wheel engagement portion 121c, an agitator receiving portion 121d, and a cleaning tank 128.

[0231] The base body 121a can form the overall shape 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.

[0232] The base body 121a can be configured such that its width (or diameter) in the horizontal direction (parallel to the X and Y axes) is greater than its height in the vertical direction (parallel to the Z axis). This configuration allows the robotic vacuum cleaner base station 100 to be stably supported on the floor surface.

[0233] A return flow path can be configured inside the base body 121a. Therefore, the air discharged from the dust collection motor 145 can flow in the return flow path formed inside the base body 121a and be discharged to the air return port 125b.

[0234] The tilting part 121b can be configured at the entrance where the robot vacuum cleaner 200 climbs from the base body 121a.

[0235] The tilting portion 121b may have a forward tilt toward the direction in which the robot vacuum cleaner 200 enters. More specifically, the tilting portion 121b is connected such that there is no height difference between the front end of the entrance side and the ground, but it can have an upward tilt that increases toward the direction in which the robot vacuum cleaner 200 enters. In this case, the front direction in which the robot vacuum cleaner 200 enters refers to the rear direction relative to the robot vacuum cleaner base station 100. As a result, the robot vacuum cleaner 200 can easily climb from the ground onto the robot vacuum cleaner base station 100.

[0236] A wheel guide 121ba may be configured in the inclined section 121b.

[0237] 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. In addition, the width of the groove at the entrance for the robotic vacuum cleaner 200 to climb is greater than the width of the wheel 260, and the width of the groove relative to the entrance narrows towards the front of the climbing path of the robotic vacuum cleaner 200. As a result, the wheels 260 of the robotic vacuum cleaner 200 can easily enter the robotic vacuum cleaner base station 100, but lateral movement is restricted by the increasingly narrow groove, thereby guiding the wheels 260 to a fixed position.

[0238] An auxiliary wheel guide 121bb may be configured in the inclined section 121b.

[0239] 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 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. Thus, when the robotic vacuum cleaner 200 travels on the inclined portion 121b, the robotic vacuum cleaner 200 can travel while being stably supported not only by the wheel 260 but also by the auxiliary wheel 270.

[0240] The wheels 260 of the robotic vacuum cleaner 200, which move upwards along the wheel guide 121ba, can be placed on the wheel engagement portion 121c. When the wheels 260 of the robotic vacuum cleaner 200 are placed on the wheel engagement portion 121c, a physical connection between the robotic vacuum cleaner 200 and the robotic vacuum cleaner base station 100 can be formed. 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 be connected to the wheel guide 121ba without any height difference. Thus, the robotic vacuum cleaner 200 can easily move to the wheel engagement portion 121c via the tilting portion 121b.

[0241] The wheel engagement portion 121c can be configured at the stop position of the left and right side wheels 260 of the sweeping robot 200 so that the sweeping robot 200 stops in a fixed position. Here, the stop position of the wheels 260 refers to a position determined in a manner that allows the sweeping robot 200 to stop in connection with the power supply terminal 123b and / or a position determined in a manner that allows the sweeping robot 200 to stop in connection with the dust bin 220 and the dust passage 123a.

[0242] The shape of the wheel engagement portion 121c can be formed to correspond to the shape of the wheel 260 of the robotic vacuum cleaner 200, that is, an arch shape. With this configuration, the robotic vacuum cleaner 200 moves along the wheel guide portion 121ba and can stop when the wheel 260 is inserted into the wheel engagement portion 121c, and the wheel 260 can be stably placed in the arched wheel engagement portion 121c.

[0243] At least a portion of the agitator 250 of the robotic vacuum cleaner 200 can be accommodated in the agitator receiving portion 121d. Specifically, the agitator receiving portion 121d can provide space to accommodate the lower end of the agitator 250 of the robotic vacuum cleaner 200 when the wheel 260 of the robotic vacuum cleaner 200 is placed in the wheel engagement portion 121c.

[0244] 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 an open cuboid. The lower 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 recess 121da through the open upper surface of the agitator receiving portion 121d. At this time, the depth of the recess 121da can be made shallower than the depth of the wheel engagement portion 121c.

[0245] The agitator receiving portion 121d may include a recessed portion 121da and a protruding portion 121db.

[0246] The recess 121da can be formed as a depression at the base 121. The recess 121da can form a receiving space for accommodating at least a portion of the agitator 250. Thus, with the wheel 260 of the sweeping robot 200 placed 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.

[0247] The receiving space of the recess 121da can communicate with the receiving space S of the placement part 120.

[0248] The protrusion 121db can be formed to protrude from the base 121. The protrusion 121db can be arranged along the edge of the recess 121da. In addition, when the agitator 250 is accommodated in the accommodating space of the recess 121da, the protrusion 121db can be arranged to be spaced a predetermined distance from the main body 210 of the robot vacuum cleaner 200.

[0249] The protrusion 121db can guide the air discharged through the air return port 125b to the suction section 211 of the robot vacuum cleaner 200. Thus, the air discharged into the receiving space of the recess 121da can be guided by the protrusion 121db to the suction section 211 of the robot vacuum cleaner 200.

[0250] An air return port 125b may be formed in the agitator housing 121d. The air return port 125b may be formed on the side of the agitator housing 121d. The air return port 125b can connect the recess 121da to the dust collection motor 145 through the return flow path. The recess 121da and the return flow path can be connected through the air return port 125b. Therefore, the air discharged from the dust collection motor 145 can be discharged through the air return port 125b to the recess 121da of the agitator housing 121d.

[0251] The connecting wall 123 is a structure in which a dust passage 123a, a power supply terminal 123b, and a water nozzle 123c of the robot vacuum base station 100 are disposed. The connecting wall 123 can spatially separate the accommodating space S from the components of the robot vacuum base station 100. The connecting wall 123 can extend vertically from the rear side of the base 121. The connecting wall 123 can be formed according 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 with a predetermined radius. With such a configuration, the outer contour of the robot vacuum 200 can be surrounded, and the area opposite to the outer surface of the robot vacuum 200 can be increased. In addition, the robot vacuum 200 can be stably supported.

[0252] A dust passage 123a can be formed in the mounting section 120 to allow air from outside the cover 110 to flow into the interior. Specifically, a dust passage 123a can be formed in the connecting wall 123 to allow air from outside the cover 110 to flow into the interior. In this case, the dust passage 123a can be located behind the dust collection cover 141, which will be described later.

[0253] The dust passage 123a can communicate with the dust bin 220 of the robotic vacuum cleaner 200. The dust passage 123a can also communicate with the dust outlet 221 of the dust bin 220 of the robotic vacuum cleaner 200. The dust passage 123a can be formed into 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 123a can be formed in a shape corresponding to the dust outlet 221 of the dust bin 220.

[0254] The dust passage 123a can be configured to communicate with the dust collection flow paths 147 and 148. After the air drawn into the dust passage 123a flows through the dust collection flow paths 147 and 148, it can be discharged through the air return section 125.

[0255] The robotic vacuum cleaner base station 100 may include a power supply module for supplying power to the robotic vacuum cleaner 200. The power supply module includes a power supply module housing and a power supply terminal 123b. A circuit board and components for power supply can be installed in the power supply module housing. Furthermore, the power supply terminal 123b is located at the front of the power supply module housing and can be configured to protrude from the connecting wall 123.

[0256] 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.

[0257] The robot vacuum cleaner base station 100 may also include a water supply nozzle 123c.

[0258] 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 a structure that connects to the water tank 230 of the robotic vacuum cleaner 200. The water supply nozzle 123c can supply water 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.

[0259] The inner wall 124 is a structure that spatially separates the accommodating space S of the mounting section 120 from the components of 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 the base 121. Specifically, the inner walls 124 can extend from the left and right sides of the base 121 in a vertical direction. The height of the inner wall 124 can be formed corresponding to the height of the support leg 21. Specifically, the height of the inner wall 124 can be formed to be the same as the height of the support leg 21.

[0260] On the other hand, various components such as dust collection paths 147 and 148, dust collection unit 140, dust collection motor 145, detergent tank 163, and wastewater tank 164 can be arranged on the outer side of the inner wall 124. Specifically, the space between the inner wall 124 and the outer wall 111 of the cover 110 can accommodate the dust collection unit 140, detergent tank 163, and wastewater tank 164.

[0261] The dust collection section 140 and the detergent container 163 can be slidably separated from the space between the inner wall 124 and the outer wall 111 of the cover 110. The left-right width of the dust collection section 140 and the detergent container 163 can be formed corresponding to the distance between the inner wall 124 and the outer wall 111 of the cover 110.

[0262] The cleaning plate 122 is a structure for cleaning the mop of the robot vacuum cleaner 200. The cleaning plate 122 can be placed in the cleaning tank 128 of the base 121. In addition, the cleaning plate 122 can contact the mop 242 when the robot vacuum cleaner 200 is placed.

[0263] The cleaning plate 122 can be a plate that is generally inclined downwards towards the center.

[0264] Specifically, the cleaning plate 122 includes a flow guiding surface 122c formed in a curved shape. Furthermore, at least one through-hole 122b through which fluid can pass can be formed in the flow guiding surface 122c. Additionally, cleaning protrusions 122a can be formed protruding from the flow guiding surface 122c.

[0265] At this time, a pair of cleaning protrusions 122a can be symmetrically formed on the flow guide surface 122c. Specifically, the pair of cleaning protrusions 122a are disposed on the vertical lower side of the pair of mop pads 242 of the robot vacuum cleaner 200, and are configured to be opposite to the pair of mop pads 242, and can be configured to be able to contact at least a portion of the pair of mop pads 242.

[0266] Furthermore, a plurality of through holes 122b are formed on the flow guiding surface 122c, which can be formed between a pair of cleaning protrusions 122a. For example, a plurality of through holes 122b are formed on the flow guiding surface 122c, including the lowest position from the ground (kitchen floor), which can be formed between a pair of cleaning protrusions 122a. Thus, fluid discharged between the pair of cleaning protrusions 122a can be guided and flowed by the through holes 122b.

[0267] On the other hand, the flow guide surface 122c moves further back from the location where the through hole 122b is formed, and the height above the kitchen floor increases. That is, the closer the flow guide surface 122c is to the external air exhaust section 171c, which will be described later, the higher it can be above the kitchen floor.

[0268] With this configuration, the flow of washing water and / or air is guided by the flow guide surface 122c and can leak through the through hole 122b into the space formed between the washing plate 122 and the washing tank 128. Thus, heated air can be supplied to the washing tank 128 through the through hole 122b.

[0269] Therefore, when the drive unit of the rotating cleaning unit 240 is driven while the mop 242 of the robotic vacuum cleaner 200 is placed on the cleaning plate 122, the mop 242 will rotate. At this time, when the mop 242 is rotated while water is being supplied to the cleaning plate, the mop 242 can be cleaned while rubbing against the cleaning protrusions 122a that are in a stopped state.

[0270] The cleaning tank 128 is a structure for placing the cleaning plate 122. The cleaning tank 128 can be disposed on the rear side of the base body 121a. The cleaning tank 128 is disposed on the lower side of the cleaning plate 122 and is detachably coupled to the cleaning plate 122. The cleaning tank 128 can be formed correspondingly to the cleaning plate 122 so that the cleaning plate 122 can be inserted. Liquid passing through the cleaning plate 122 can flow into the cleaning tank 128.

[0271] The cleaning tank 128 may include a cleaning tank base surface for fluid flow through the cleaning plate 122 and a cleaning tank wall extending vertically from the outer contour of the cleaning tank base surface. The cleaning tank base surface can be positioned lower above the ground (kitchen floor) as it moves towards the rear of the robot vacuum base station 100. This allows the fluid flowing through the cleaning plate 122 to be concentrated at the rear of the cleaning tank 128, and allows it to be discharged to the outside through the wastewater inlet 164c, which will be described later.

[0272] Dust Collection Department

[0273] exist Figures 12 to 16 The figure shows a dust collection section of a robot vacuum cleaner base station used to illustrate an embodiment of the present invention.

[0274] Reference Figures 12 to 16 and Figure 19 The following is an explanation of the dust collection section 140.

[0275] The dust collection unit 140 is capable of collecting dust from the dust bin 220 of the robotic vacuum cleaner 200. The dust collection unit 140 can be disposed inside the housing 110. The dust collection unit 140 can also be disposed outside the mounting portion 120. That is, the dust collection unit 140 can be disposed between the housing 110 and the mounting portion 120. For example, the dust collection unit 140 can be disposed on one side of the mounting portion 120 in the left-right direction. In this case, the accommodating space S can be disposed inside the mounting portion 120. Thus, despite height limitations, the components required for dust collection can be disposed.

[0276] 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.

[0277] 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.

[0278] The dust collection unit cover 141 has a dust bag drawer 144 that can be pulled out internally, and a dust bag (not shown) can be stored inside the dust bag drawer 144. For example, the dust collection unit cover 141 is formed as a rectangular tube open at the front, and the rear internal space can be connected to the first dust collection flow path 147 and the second dust collection flow path 148.

[0279] Dust inside the dust bin 220 can flow into the dust collection unit cover 141.

[0280] 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.

[0281] Specifically, the dust collection section cover 141 may have an inlet 141a communicating with the first dust collection flow path 147 and an outlet 141b communicating with the second dust collection flow path 148.

[0282] At this time, the inlet 141a can be positioned above the outlet 141b. Thus, air and dust flowing in through the inlet 141a flow downwards, and after the dust is captured by the dust bag (not shown), it can be discharged through the outlet 141b. During this process, since the air flows from top to bottom, it has the effect of preventing air from flowing upwards or dust from scattering upwards.

[0283] A dust bag (not shown) refers to a bag used by the dust collection motor 145 to collect dust sucked into the dust bin 220 of the robotic vacuum cleaner 200. The dust bag (not shown) can be detachably attached to the dust collection cover 141. Therefore, the dust bag (not shown) can be separated from the dust collection cover 141 and discarded, and a new dust bag (not shown) can be attached to the dust collection cover 141. That is, the dust bag (not shown) can be defined as a consumable part.

[0284] The dust bag (not shown) can be configured such that when suction is generated by the dust collection motor 145, dust is contained inside as its volume increases.

[0285] Therefore, the dust bag (not shown) can be made of a material that allows air to pass through but not foreign objects such as dust. For example, the dust bag (not shown) can be made of non-woven fabric and can have a hexahedral shape that corresponds to the shape of the dust collection unit cover 141 when the volume increases.

[0286] Filter 142 can be configured between the dust collection unit shroud 141 and the second dust collection flow path 148. Filter 142 can be configured at the outlet 141b. Filter 142 can be a pre-filter or a high-efficiency particulate air (HEPA) filter. Air passing through the dust bag (not shown) can flow into the second dust collection flow path 148 through filter 142.

[0287] The dust bag drawer 144 is designed to be pulled out from the dust collection unit cover 141 and can hold a dust bag (not shown).

[0288] At this time, refer to Figure 19 The dust bag drawer 144 includes a dust bag drawer body 144a, a handle 144d, and a drawer slide 144e.

[0289] The dust bag drawer body 144a can provide internal space for assembling a dust bag (not shown). For example, the dust bag drawer body 144a can be formed in the shape of a box with an open top, and an inlet 144b and an outlet 144c can be formed at the rear so as to communicate with the first dust collection path 147 and the second dust collection path 148.

[0290] For example, the dust bag drawer body 144a can be formed such that the width in the upper left-right direction is different from the width in the lower left-right direction. For example, the width in the upper left-right direction of the dust bag drawer body 144a can be formed such that the width in the upper left-right direction is greater than the width in the lower left-right direction. That is, the interior of the dust bag drawer body 144a can be formed in a platform shape. As a result, the upper space containing the dust bag (not shown) can be maximized, and an airflow path can be formed in a way that allows air passing through the dust bag (not shown) to easily leak downwards.

[0291] The upper side of the dust bag drawer body 144a can be connected to the first dust collection path 147 via the inlet 144b. The inlet 144b can be a structure that guides the air flowing in the first dust collection path 147 into the interior of the dust bag (not shown). The inlet 144b can connect the first dust collection path 147 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 inlet 144b.

[0292] The dust bag drawer 144 can communicate with the second dust collection path 148 via an outlet 144c formed on its lower side. The outlet 144c can be a structure that guides air passing through the dust bag drawer 144 to the second dust collection path 148. The outlet 144c can be configured at a different height than the inlet 144b. The outlet 144c can be configured to be lower than the inlet 144b. The outlet 144c can communicate the internal space of the dust bag drawer 144 with the second dust collection path 148. Therefore, air that has been filtered of dust while passing through the dust bag (not shown) can move to the second dust collection path 148 through the outlet 144c.

[0293] A handle 144d may be provided on the front of the dust bag drawer body 144a. The handle 144d may be configured to be gripped by a user. For example, the handle 144d may include: a pair of hinged joints that are hinged to the front of the dust bag drawer body 144a; and a gripping part that connects the pair of hinged joints to allow the user to grip it.

[0294] With this configuration, when the user grasps the handle and pulls it forward, the dust bag drawer body 144a can also be pulled forward and extended. Therefore, according to this invention, the user can easily pull the dust bag drawer 144 forward and then lift the dust bag (not shown) upward for removal and replacement.

[0295] Drawer slides 144e can be formed on the left and right sides of the dust bag drawer body 144a. The drawer slides 144e can guide the movement of the dust bag drawer body 144a.

[0296] For example, drawer slides 144e can be formed in the left and right sides of the dust bag drawer body 144a in the front-back direction as grooves or ribs.

[0297] With this configuration, when the user attaches the dust bag drawer 144 to the dust collection unit cover 141, they can be attached in a fixed position, and the dust collection unit 140 can be connected to the first dust collection flow path 147 and the second dust collection flow path 148 in a fixed position, thereby reducing flow loss.

[0298] On the other hand, corresponding to the drawer slide 144e, a guide rail 141a can also be formed on the inner side of the dust collection cover 141. The guide rail 141a of the dust collection cover 141 can be formed in a shape and position corresponding to the drawer slide 144e. For example, if the drawer slide 144e is formed in a groove shape, the guide rail 141a of the dust collection cover 141 can be formed in a rib or a protruding jaw shape.

[0299] On the other hand, the dust collection unit 140 may also include dust collection flow paths 147 and 148. The dust collection flow path may refer to the flow path through which air drawn in through the dust through-hole 123a flows through the dust bag to the dust collection motor 145.

[0300] Specifically, the dust collection path may include: a first dust collection path 147 that connects the dust bin 220 to the internal space of the dust collection unit cover 141 when the sweeping robot 200 is combined with the sweeping robot base station 100 and the dust passage 123a is connected to the dust bin 220 of the sweeping robot 200, and a second dust collection path 148 that connects the internal space of the dust collection unit cover 141 to the internal space of the dust collection motor cover 146.

[0301] The first dust collection path 147 connects the dust bin 220 of the robotic vacuum cleaner 200 to the internal space of the dust collection cover 141. The first dust collection path 147 also connects the dust passage 123a of the placement part 120 to the internal space of the dust collection cover 141. The first dust collection path 147 refers to the space between the dust bin 220 of the robotic vacuum cleaner 200 and the dust collection cover 141. The first dust collection path 147 can be formed in a direction intersecting the vertical direction. For example, the first dust collection path 147 can be formed in a direction close to the horizontal direction. The first dust collection path 147 can be a space formed rearward from the dust passage 123a, or a path that bends laterally from the dust passage 123a and allows dust and air to flow. Dust in the dust bin 220 of the robotic vacuum cleaner 200 can be moved to the internal space of the dust collection cover 141 through the first dust collection path 147.

[0302] The second dust collection path 148 connects the internal space of the dust collection unit cover 141 with the internal space of the dust collection motor cover 146. The second dust collection path 148 can be formed in a direction intersecting the vertical direction. For example, the second dust collection path 148 can be formed in a direction close to the horizontal direction.

[0303] In this invention, the first dust collection path 147 and the second dust collection path 148 can be formed at different heights. That is, the first dust collection path 147 and the second dust collection path 148 can be configured in a stacked structure. In this case, the second dust collection path 148 can be configured to be lower than the first dust collection path 147. That is, at least a portion of the first dust collection path 147 can be configured above the second dust collection path 148.

[0304] With this configuration, multiple flow paths can be configured in a near-horizontal direction to reduce the overall height, while they can be stacked to minimize the lateral width and overall volume of the robotic vacuum cleaner base station 100.

[0305] On the other hand, in this embodiment, the first dust collection path 147 and the second dust collection path 148 can be formed to pass through the same side of the dust collection cover 141. That is, the first dust collection path 147 and the second dust collection path 148 can be formed to pass through the rear side of the dust collection cover 141.

[0306] That is, in this embodiment, air can flow in from the rear side of the dust collection unit cover 141 and then be discharged to the rear side again.

[0307] With this configuration, the air flowing in the first dust collection path 147 can have different flow directions than the air flowing in the second dust collection path 148. That is, the air flowing in the first dust collection path 147 can flow from back to front, while the air flowing in the second dust collection path 148 can flow from front to back.

[0308] Therefore, according to this utility model, the space occupied by the first dust collection path 147 and the front-to-back space occupied by the second dust collection path 148 can be shared, and the overall space efficiency can be improved.

[0309] The dust collection unit 140 may also include a dust collection module. The dust collection module is capable of providing suction airflow to the dust collection flow path.

[0310] Specifically, the dust collection unit 140 may also include a dust collection motor cover 146 and a dust collection motor 145.

[0311] The dust collection motor cover 146 can be disposed inside the cover 110. The dust collection motor cover 146 can house the dust collection motor 145. The dust collection motor cover 146 can be disposed behind the dust collection section cover 141. Additionally, the dust collection motor cover 146 can be disposed behind the first dust collection flow path 147. Furthermore, the dust collection motor cover 146 can be disposed behind the second dust collection flow path 148.

[0312] That is, taking the front-to-back direction of the robot vacuum base station 100 as a reference, the dust collection unit cover 141 is positioned at the front, and the first dust collection flow path 147 and the second dust collection flow path 148 can be positioned behind the dust collection unit cover 141. Furthermore, the dust passage 123a is positioned further back than the first dust collection flow path 147, and the dust collection motor cover 146 can be positioned further back than the second dust collection flow path 148. Additionally, the dust collection motor cover 146 can be positioned further back than the dust passage 123a.

[0313] Therefore, the dust collection unit 140 is configured along the front-rear direction of the robot vacuum cleaner base station 100, thereby reducing the overall height.

[0314] The internal space of the dust collection motor housing 146 can communicate with the second dust collection flow path 148. Therefore, the air flowing in the second dust collection flow path 148 can be guided to the dust collection motor 145.

[0315] The internal space of the dust collection motor housing 146 can be connected to the return flow path. Therefore, the air passing through the dust collection motor 145 can be guided to the return flow path.

[0316] The dust collection motor 145 is capable of generating suction in the dust collection flow path. That is, the dust collection motor 145 is capable of providing suction to draw dust from the dust bin 220 into the dust bag disposed in the dust collection unit cover 141.

[0317] The dust collection motor 145 can be configured behind the dust collection unit cover 141. Thus, the dust collection motor 145 can provide suction power to suck up dust from the dust bin 220 of the robot vacuum cleaner 200.

[0318] The dust collection motor 145 is capable of generating suction by rotation. As an example, although not shown, the dust collection motor 145 may include a rotor and a stator that rotate relative to each other when a power source is applied, and may include an impeller that rotates about a rotation axis as the rotor rotates. Therefore, suction can be generated by the rotation of the impeller.

[0319] One side of the dust collection motor 145 can be connected to the second dust collection flow path 148, and the other side can be connected to the return flow path. When the dust collection motor 145 is driven, the air flowing in the second dust collection flow path 148 can flow into the interior of the dust collection motor housing 146. In addition, the air flowing into the interior of the dust collection motor housing 146 can flow in the return flow path after passing through the dust collection motor 145 and be discharged to the air return port 125b.

[0320] On the other hand, the rotation axis of the dust collection motor 145 can be formed in a nearly horizontal direction. With this configuration, the overall volume of the robot vacuum base station 100, which is installed in the kitchen cabinet 2 or the installation space 21a of the structure, can be minimized.

[0321] 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.

[0322] The air return section 125 can guide the air discharged from the dust collection motor 145 to the robot vacuum cleaner 200.

[0323] The air return section 125 can be composed of a return flow path 125a and an air return port 125b.

[0324] The return flow path 125a provides a flow path for the air discharged from the dust collection motor 145. The return flow path 125a can be configured inside the base body 121a. For example, the return flow path 125a can be a space formed between the upper and lower sides of the base body 121a.

[0325] Therefore, at least a portion of the return flow path 125a can pass through the lower side of the base 121. At the same time, at least a portion of the return flow path 125a can be configured at a position lower than the robotic vacuum cleaner 200 placed on the upper side of the base body 121a.

[0326] Therefore, by effectively utilizing the remaining space inside the base 121 to form the return flow path 125a, the height of the robot vacuum base station 100 can be prevented from increasing. Since no separate space is needed to form the flow path, space efficiency can be maximized.

[0327] The return flow path 125a can be connected to the dust collection motor 145 in a flow path manner. The return flow path can refer to the flow path connecting the internal space of the dust collection motor housing 146 and the air return port 125b. One end of the return flow path 125a can communicate with the internal space of the dust collection motor housing 146, and the other end of the return flow path 125a can communicate with the air return port 125b.

[0328] The return flow path 125a can be a flow path formed in a direction that intersects the vertical direction. For example, the return flow path 125a can be a flow path formed in a horizontal direction inside the cover 110.

[0329] At this time, at least a portion of the return flow path 125a can be positioned lower than the first dust collection flow path 147. That is, the return flow path 125a can be configured to pass under the first dust collection flow path 147. Therefore, the air flowing in the first dust collection flow path 147 can intersect the flow direction of the air flowing in the return flow path 125a in the horizontal plane.

[0330] Therefore, by arranging the first dust collection path 147 and the return path 125a vertically (stacked) within a limited height, space efficiency can be maximized.

[0331] The air return port 125b serves as an outlet for guiding the air discharged from the dust collection motor 145 to the receiving space of the recess 121da.

[0332] An air return port 125b can be formed on the base 121. An air return port 125b can also be formed on the agitator housing 121d. An air return port 125b can also be formed on the sidewall of the recess 121da. In this case, the suction section 211 of the sweeping robot 200 can be disposed on the upper side of the agitator housing 121d. Therefore, the return flow path 125a can discharge air to the lower side of the suction section 211, and the air passing through the return flow path 125a can flow into the suction section 211 disposed immediately above it.

[0333] Therefore, the return flow path 125a of this embodiment of the present invention can guide the air discharged from the dust collection motor 145 to the suction section 211 of the sweeping robot 200.

[0334] The return flow path 125a does not exhaust the air expelled from the dust collection motor 145 to the outside, but instead guides it to the suction section 211 of the robot vacuum 200, thereby creating a structure in which air continuously circulates between the robot vacuum 200 and the robot vacuum base station 100. As a result, the hot air expelled from the dust collection motor 145 is not exhausted into the kitchen cabinet 2, but instead flows back into the interior of the robot vacuum 200 for recirculation, thus preventing damage to the interior of the kitchen cabinet 2.

[0335] Air drawn from the dust collection motor 145 can be discharged into the receiving space S through the air return port 125b. The air discharged into the receiving space S can flow back into the suction section 211 due to the suction of the dust collection motor 145. Therefore, the air drawn from the dust bin 220 due to the suction of the dust collection motor 145 can flow sequentially through the dust passage 123a, the first dust collection flow path 147, the dust collection section cover 141, the second dust collection flow path 148, the dust collection motor 145, the return flow path 125a and the air return port 125b before being discharged into the receiving space S.

[0336] At this time, when 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 force of the suction motor (not shown) in addition to the suction force of the dust collection motor 145, thus improving the dust collection efficiency.

[0337] Cleaning section

[0338] exist Figure 17 The figure shows an enlarged view of the mop cleaning section of the robot vacuum cleaner base station used to illustrate an embodiment of the present invention. Figure 18 The figure shows an enlarged view of the washing water supply unit of the mop cleaning section of the robot vacuum cleaner base station used to illustrate an embodiment of the present invention. Figure 19 The diagram illustrates the state after the dust collection unit and detergent tank are pulled out from the base station of the sweeping robot according to an embodiment of the present invention.

[0339] Reference Figures 17 to 19 The cleaning unit 160 of the robot vacuum cleaner base station 100 of this embodiment will be described below.

[0340] The robotic vacuum cleaner base station 100 of this embodiment may include a cloth cleaning unit 160. The cloth cleaning unit 160 is capable of cleaning the cloth 242 of the robotic vacuum cleaner 200 which is combined with the placement unit 120.

[0341] The rag washing unit 160 may include: a washing water supply unit 161 that dispenses washing water to the washing plate 122; a detergent tank 163 that stores liquid containing detergent; and a wastewater tank 164 that stores washing water after the rags 242 have been washed.

[0342] In the washing water supply section 161, purified water and detergent can be mixed to generate washing water for cleaning the rag 242.

[0343] 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.

[0344] At this time, the washing water outlets 161e can be arranged in pairs on the rear side of the connecting wall 123. The washing water outlets 161e can discharge washing water from the upper side of the cleaning plate 122. For example, a pair of washing water outlets 161e can be arranged on the upper side of a pair of cleaning protrusions 122a.

[0345] At this time, the purified water supplied from the water supply pipe of the kitchen cabinet 2 and passing through the regulator 162 can branch off to both sides through the branch flow path 161a, connecting to the separately arranged washing water outlets 161e. That is, the branch flow path 161a can be configured as 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 remaining one 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.

[0346] The washing water outlet 161e can be integrally formed with the bonding wall 123 on the rear side of the bonding wall 123, or can be detachably bonded to the bonding wall 123.

[0347] The purified water inlet 161b is a structure that guides purified water supplied from the water supply pipe of the kitchen cabinet 2 to the washing water supply unit 161. Specifically, the water supply pipe of the kitchen cabinet 2 is connected to a regulator 162, which can 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, and the remainder can flow into a pair of washing water supply units 161 arranged separately from each other through the purified water inlet 161b.

[0348] The detergent inlet 161c is a structure that guides liquid containing detergent supplied from the detergent tank 163 to the wash water supply unit 161. Specifically, liquid containing detergent stored in the detergent tank 163 can be supplied to the wash water supply unit 161 using the detergent pump 161d.

[0349] Additionally, the detergent flowing into the washing water supply unit 161 is mixed with purified water and can be effectively used as washing water. The washing water supply unit 161 can discharge washing water onto the upper surface of the cleaning plate 122 through the washing water discharge port 161e. The washing water discharge port 161e can open in a direction opposite to the upper surface of the cloth 242 placed on the cleaning plate 122.

[0350] Detergent container 163 can store liquid containing detergent.

[0351] The detergent container 163 includes a detergent container body 163a, a handle 163b, and a detergent container guide rail 163c (see figure).

[0352] The detergent container body 163a provides 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.

[0353] 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 formed to connect the pair of connecting parts so that the user can grip it.

[0354] With this configuration, when 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.

[0355] Detergent tub guide rails 163c can be formed on the left and right sides of the detergent tub body 163a. ​​The detergent tub guide rails 163c can guide the movement of the detergent tub body 163a.

[0356] For example, the detergent tub guide rail 163c can be formed in the left and right sides of the detergent tub body 163a in the front-back direction as a groove or rib.

[0357] With this configuration, when the user attaches the detergent container 163 to the cover 110, the detergent container 163 can be fixed in a fixed position, and the washing water leakage can be prevented.

[0358] On the other hand, although not shown, a guide rail can be formed on the cover 110 corresponding to the detergent tub guide rail 163c. The guide rail can be formed in a shape and position corresponding to the detergent tub guide rail 163c.

[0359] The wastewater tank 164 provides space for storing the washing water after washing the cloths 242. The washing water discharged onto the upper surface of the washing plate 122 can drain into the through-hole 122b as it descends along the inclined surface of the washing plate 122 after washing the cloths 242. The washing water through the through-hole 122b accumulates in the washing tank 128. Additionally, the washing water accumulated in the washing tank 128 can flow into the wastewater suction path 164b through the wastewater inlet 164c, and then into the wastewater tank 164 through the wastewater inlet 164b. In other words, the liquid passing through the washing plate 122 can flow along the washing tank 128 and be discharged through the wastewater inlet 164c.

[0360] On the other hand, a sewage suction flow path 164b is formed in a sewage suction pipe, with a sewage inlet 164c formed at one end of the sewage suction pipe, and the other end of the sewage suction pipe communicating with a sewage tank 164. In this case, the sewage suction pipe can be configured to pass under the external air supply module 171. That is, the sewage suction flow path 164b can be configured under the external air supply module 171. Alternatively, the sewage suction flow path 164b can be configured under the external air supply flow path 171a.

[0361] Washing water stored in the wastewater tank 164 can be discharged to the drain pipe 25 of the kitchen cabinet 2 through the wastewater discharge passage 164a. One end of the wastewater discharge passage 164a can be connected to the wastewater tank 164, and the other end can be connected to the drain pipe 25. At this time, the washing water stored in the wastewater tank 164 can be discharged to the drain pipe by using a centrifugal pump (not shown) to flow through the wastewater discharge passage 164a.

[0362] The sewage discharge path 164a connected to the sewage tank 164 can be connected upstream 25b with reference to the U-bend 25a of the drain pipe 25 of the kitchen cabinet 2. This is because if the sewage discharge path 164a is connected downstream 25c with reference to the U-bend 25a of the drain pipe 25, foul odors or fluids inside the drain pipe 25 may flow back into the sewage discharge path 164a.

[0363] 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.

[0364] 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.

[0365] Cloth Drying Section

[0366] exist Figure 20 The figure shows a perspective view of the cloth drying section of a robot vacuum cleaner base station used to illustrate an embodiment of the present invention. Figure 21 The figure shows an enlarged view of the cloth drying section of the robot vacuum cleaner base station according to an embodiment of the present invention. Figure 22 The figure shows a cross-sectional view illustrating the flow of air inside the hot air supply module of an embodiment of the present invention.

[0367] Reference Figures 20 to 22 In one embodiment of this utility model, the robot vacuum cleaner base station 100 may include a cloth drying unit 170. In this case, the cloth drying unit 170 can dry the cloth 242 of the robot vacuum cleaner 200 after it has been cleaned by the cloth cleaning unit 160 or the cloth 242 that is wet after the water cleaning operation is completed.

[0368] One embodiment of the present invention, the cloth drying unit 170, may include an external air supply module 171, an air exhaust unit 172, an exhaust fan 173, and a check valve 175.

[0369] The external air supply module 171 is capable of supplying hot air to the accommodating space S, and may include an external air supply flow path 171a, an external air inlet 171b, an external air outlet 171c, a heater 171d, and a blower fan 171e.

[0370] An external air supply flow path 171a is formed in the external air supply module 171. The external air supply flow path 171a enables external air to flow to the external air discharge section 171c.

[0371] The external air supply path 171a can connect the external space of the enclosure 110 with the receiving space S. One side of the external air supply path 171a can be connected to the external space through the external air inlet 171b, and the other side of the external air supply path 171a can be connected to the receiving space S through the external air outlet 171c.

[0372] An external air inlet 171b may be formed on the rear side of the housing 110. A plurality of external air inlets 171b may be formed on the rear side of the housing 110. Air from outside the housing 110 can flow into the external air supply path 171a through the external air inlets 171b. Therefore, air from outside the housing 110 can flow into the interior of the housing 110.

[0373] At least a portion of the external air outlet 171c may be disposed on the upper side of the cleaning plate 122. The external air outlet 171c may open in a direction opposite to the cleaning plate 122. A pair of external air outlets 171c may be provided in a downward-opening state.

[0374] The external air outlet 171c can discharge air supplied through the external air supply path 171a. The external air outlet 171c can also discharge air heated in the heater 171d. For example, an external air outlet can be formed in the external air outlet 171c.

[0375] With the cloth 242 placed on the cleaning plate 122, the external air exhaust portion 171c can open to the upper side of the cloth 242. Therefore, the external air exhaust portion 171c is located adjacent to the cloth 242, opens downward, and the air discharged from the external air exhaust portion 171c can flow towards the cloth 242.

[0376] The blower fan 171e is configured in the external air supply flow path 171a and is capable of supplying air to the accommodating space S. When the blower fan 171e is driven, the air flowing in through the external air inlet 171b can be heated by the heater 171d and discharged into the accommodating space S through the external air outlet 171c.

[0377] Heater 171d is disposed in external air supply flow path 171a and is capable of heating the air flowing in external air supply flow path 171a. Heater 171d is also capable of heating the air discharged through external air outlet 171c.

[0378] The heater 171d may include a heater housing and a heating element. The heater housing may be configured in the external air supply path 171a, and may have an internal space capable of accommodating 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 through the external air outlet 171c into the accommodating space S, thereby drying the wet cloth 242.

[0379] The air exhaust unit 172 can exhaust the hot and humid air generated inside the robot vacuum base station 100 to the drain pipe 25 while drying the rag 242. Specifically, the air exhaust unit 172 can connect the receiving space S to the drain pipe 25 of the kitchen cabinet 2.

[0380] An air discharge path can be formed in the air discharge section 172. At this time, one end of the air discharge path can be connected to the receiving space S, and the other end can be connected to the drain pipe 25. Specifically, the air intake 172a, which is one end of the air discharge path, can be connected to the receiving space S, and the air outlet 172b, which is the other end, can be connected to the drain pipe 25.

[0381] 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. For yet another example, the air intake 172a can be disposed on the ground higher than the cloth 242, and can be disposed in a position forward of the external air exhaust portion 171c. Thus, air containing steam generated during the drying process of the cloth 242 can be discharged.

[0382] The air exhaust section 172 can be connected downstream 25c based on the U-bend 25a of the drain pipe 25 of the kitchen cabinet 2. This is because, if the air exhaust section 172 is connected upstream 25b based on the U-bend 25a of the drain pipe 25, the water accumulated in the U-bend 25a may prevent the hot air exhausted through the air exhaust section 172 from passing through the drain pipe 25.

[0383] On the other hand, in one embodiment of this invention, the air exhaust path can be located inside the cover 110, with one pipe branching into two and 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, air drawn in from the air exhaust portion 172 can flow towards the air exhaust ports 172b of the two branches and be discharged downstream 25c based on the U-shaped bend 25a of the drain pipe 25.

[0384] The exhaust fan 173 can exhaust air flowing in through the air intake 172a to the drain pipe 25. The exhaust fan 173 can cause air flowing into the air exhaust section 172 to circulate. The exhaust fan 173 can be disposed in the air exhaust flow path section.

[0385] When the exhaust fan 173 is driven, air in the accommodating space S can flow into the air intake 172a. The air flowing into the air intake 172a can flow in the air exhaust section 172 and be discharged to the drain pipe 25. Specifically, the air flowing in the air exhaust section 172 when the exhaust fan 173 is driven can be exhausted downstream 25c based on the U-shaped bend 25a of the drain pipe 25.

[0386] 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.

[0387] layout

[0388] Figure 23 and Figure 24 The diagram illustrates the configuration relationship of the robot vacuum cleaner base station on a horizontal plane, which is used to explain an embodiment of the present invention.

[0389] Reference Figure 4 , Figure 23 and Figure 24 The configuration of the robot vacuum cleaner base station 100 according to an embodiment of the present invention will be described as follows.

[0390] The robot vacuum cleaner base station 100 of this utility model is characterized in that it is installed in the lower space of the kitchen cabinet 2.

[0391] Therefore, the robot vacuum cleaner base station 100 of this utility model is characterized in that it is arranged horizontally to match the space between the lower side panel 23 formed in the kitchen cabinet 2 and the kitchen floor.

[0392] Specifically, in embodiments of the present invention, the dust collection section 140 and / or the cloth cleaning section 160 of the robot vacuum base station 100 can be configured on the side of the entrance 127.

[0393] 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.

[0394] For example, an entrance / exit 127 and a door 126 may be configured at the front of the robot vacuum base station 100. Furthermore, a mounting section 120 for attaching the robot vacuum 200 may be configured from the entrance / exit 127 to the rear. In this case, the dust collection section 140 may be configured from the front to the rear of the robot vacuum base station 100 by a predetermined length. Additionally, the mop cleaning section 160 may also be configured from the front to the rear of the robot vacuum base station 100 by a predetermined length.

[0395] Therefore, when the robot vacuum station 100 is viewed from the front outside, the front end of the dust collection unit 140 and / or the front end of the mop cleaning unit 160 can be arranged on the left and right sides of the entrance 127.

[0396] At this time, the dust bag (not shown) of the dust collection unit 140 can be configured to be pulled out towards the front of the cover 110. In addition, the detergent bucket 163 of the cloth washing unit 160 can be configured to be pulled out towards the front of the cover.

[0397] 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.

[0398] With this configuration, when a user wants to pull out the dust bag (not shown) or the detergent container 163, the pull position can be immediately identified, providing the convenience of pulling out the dust bag (not shown) or the detergent container 163 with a simple action of pulling the handle.

[0399] On the other hand, the rear ends of the dust collection unit cover 141 and the detergent tank 163 can be configured to be separated from the rear end of the cover 110 by a predetermined interval. Furthermore, the dust collection motor 145 can be arranged between the rear end of the dust collection unit cover 141 and the rear end of the cover 110. This configuration facilitates the connection of the power supply wire to the dust collection motor 145. Additionally, it minimizes the overall space occupied by the mounting section 120, the dust collection unit cover 141, and the dust collection motor 145 within a limited space.

[0400] Furthermore, at least a portion of a flow path for the washing water used to clean the cloth 242 and a pump that provides the flow force for the washing water can be arranged between the rear end of the cover 110 and the rear end of the detergent tank 163. This configuration minimizes the distance the washing water travels from the water supply pipe. Additionally, it minimizes the overall space occupied by the housing 120, the cloth detergent tank 163, and the flow path for the washing water within a limited space.

[0401] On the other hand, the mop drying section 170 of the robot vacuum cleaner base station 100 can be configured at a position further rear than the mounting section 120. In this case, the mop drying section 170 can be configured between the rear end of the mounting section 120 and the rear end of the cover 110.

[0402] Therefore, the robot vacuum cleaner base station 100 of this utility model can be based on the placement part 120 and the dust collection part 140 and the cloth washing part 160 are arranged on the left and right sides, and the cloth drying part 170 is arranged on the rear side.

[0403] That is, the robot vacuum cleaner base station 100 of the present invention can be equipped with a dust collection unit 140, a cloth washing unit 160 and a cloth drying unit 170 within a specified distance from the outer contour of the placement unit 120.

[0404] With this configuration, the placement section 120, the dust collection section 140, the cloth washing section 160, and the cloth drying section 170 can be arranged simultaneously in the narrowest space on the horizontal plane.

[0405] This minimizes flow path loss by shortening the distance between the dust bin 220 and the dust collection unit 140 of the robotic vacuum cleaner 200. Furthermore, minimizing the distance between the mop 242 and the mop washing unit 160, and between the mop 242 and the mop drying unit 170 of the robotic vacuum cleaner 200, limits the area where washing water and wastewater remain after washing.

[0406] In addition, with this configuration, the sweeping robot base station 100 of this utility model can arrange all its components within a limited height.

[0407] Specifically, based on the state where the robotic vacuum cleaner 200 is attached to the mounting section 120, at least a portion of the dust collection section 140 can be configured below the uppermost point of the robotic vacuum cleaner 200. Additionally, at least a portion of the mop washing section 160 can be configured below the uppermost point of the robotic vacuum cleaner 200. Furthermore, at least a portion of the mop drying section 170 can be configured below the uppermost point of the robotic vacuum cleaner 200.

[0408] 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.

[0409] As a result, the robot vacuum base station 100 of this embodiment can be configured with a dust collection unit 140, a mop washing unit 160, and a mop drying unit 170 on three sides of the surrounding mounting portion 120, excluding the front side where the robot vacuum 200 enters. With this configuration, even when the vertical height is limited, it is possible not only to charge the robot vacuum 200 with minimal horizontal space, but also to collect dust from the robot vacuum 200, wash the mop 242, and dry the mop 242.

[0410] drawer

[0411] When the charging dock of the robotic vacuum cleaner is positioned under the kitchen cabinet, its external exposure is minimized, thus enhancing the aesthetic appeal. However, if the robotic vacuum cleaner malfunctions while inside the cabinet or if the charging dock itself fails, it presents a limitation: the user may find it difficult to remove and repair it. To address this issue, a drawer 190 can be added to the robotic vacuum cleaner base station 100 in this invention.

[0412] Regarding this point, Figure 25 The diagram illustrates a state where a drawer is provided in the base station of a sweeping robot according to an embodiment of the present invention. Figure 26 The diagram illustrates the state in which the drawer is pulled out from the base station of the robot vacuum cleaner according to an embodiment of the present invention.

[0413] Reference Figure 25 and Figure 26 The drawer 190 of the robot vacuum cleaner base station 100 according to one embodiment of the present invention will be described below.

[0414] The robot vacuum cleaner base station 100 of one embodiment of the present invention may further include a drawer 190 that can be pulled out from the cover 110.

[0415] With drawer 190 introduced into cover 110, door 126 can be closed when robot vacuum 200 enters placement section 120. In this case, the inside and outside of cover 110 of robot vacuum 200 can be blocked by door 126.

[0416] Therefore, it is possible to prevent dust from scattering to the outside of the robot vacuum base station 100 while the robot vacuum 200 is collecting dust in the dust bin 220 inside the housing 110. In addition, it is possible to prevent wastewater from leaking to the outside of the robot vacuum base station 100 while the mop 242 is being washed.

[0417] Drawer 190 can move relative to cover 110. For example, cover 110 can be fixedly attached to kitchen cabinet 2, and drawer 190 can be pulled forward from cover 110.

[0418] At this time, drawer 190 can be pulled out with the internal storage compartment 120. With this configuration, when drawer 190 is pulled out, the storage compartment 120 and / or the robot vacuum cleaner 200 can be pulled out from the kitchen cabinet 2.

[0419] At this time, when the drawer 190 is pulled out from the cover 110 with the door 126 sealing the entrance 127, the robot vacuum cleaner 200 located in the mounting section 120 can be exposed to the outside.

[0420] Therefore, according to this embodiment, when the robot vacuum base station 100 needs to be repaired or cleaned, the user can easily pull out the installation part 120 and / or the robot vacuum 200 through the drawer 190, thereby exposing the internal components of the robot vacuum base station 100 or the robot vacuum 200.

[0421] On the other hand, in one embodiment of the present invention, the drawer 190 can be pulled out with the dust collection section 140 inside. That is, the drawer 190 can be pulled out together with the dust collection section 140.

[0422] On the other hand, the dust collection part 140 of this invention can be separated from the drawer 190 and pulled out from the cover 110. At this time, the pulling direction of the dust collection part 140 can be parallel to the pulling direction of the drawer 190. For example, the pulling direction of the dust bag drawer 144 can be parallel to the pulling direction of the drawer 190.

[0423] Furthermore, in one embodiment of this invention, the drawer 190 can be pulled out with at least a portion of the cloth washing section 160 inside. That is, the drawer 190 can be pulled out together with at least a portion of the cloth washing section 160. For example, the drawer 190 can be pulled out together with the detergent container 163 and the wastewater container 164.

[0424] On the other hand, the detergent container 163 of this invention can be separated from the drawer 190 and pulled out from the cover 110. At this time, 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.

[0425] With this configuration, the robot vacuum cleaner base station 100 of one embodiment of the present invention can be configured such that the pull-out directions of the drawer 190, the dust collection part 140 and the detergent bucket 163 are all parallel.

[0426] Therefore, the user can easily identify the pull-out direction of the components of the sweeping robot base station 100 of this utility model and can easily pull it out for repair and maintenance.

[0427] Drawer 190 includes drawer sidewalls 191, fitting part 192, and drawer slides 193.

[0428] The drawer sidewalls 191 are configured to be movable relative to each other between the drawer sidewalls 191 and the outer wall surfaces of the cover 110. For example, a pair of drawer sidewalls 191 may be configured to face the outer wall surfaces of a pair of cover 110.

[0429] At this time, the pair of drawer sidewalls 191 can be positioned closer to the inner side of the robot vacuum base station 100 than the outer wall surfaces of the pair of covers 110. That is, the pair of drawer sidewalls 191 can be positioned closer to the mounting portion 120 than the outer wall surfaces of the pair of covers 110.

[0430] At this time, the pair of drawer sidewalls 191 can be directly connected to the base 121 of the mounting part 120. Alternatively, the pair of drawer sidewalls 191 can be connected by a drawer base (not shown) and move together with the mounting part 120 on the upper side of the drawer base (not shown).

[0431] On the other hand, a dust collection section 140 and / or a cloth cleaning section 160 may be arranged between the drawer side wall 191 and the mounting section 120. That is, based on the state in which the robot vacuum cleaner 200 is attached to the mounting section 120, the dust collection section 140 and / or the cloth cleaning section 160 may be arranged between the robot vacuum cleaner 200 and the drawer side wall 191.

[0432] This configuration allows for the efficient use of minimal horizontal space to arrange the dust collection unit 140 and the cloth washing unit 160.

[0433] A mating part 192 is provided on the drawer side wall 191 and is detachably connected to at least one of a flexible hose and a wire. For example, the mating part 192 may be disposed on the drawer side wall 191 and connected to a flexible hose and / or a wire.

[0434] The mating part 192 is attached to the drawer side wall 191. One side of the mating part 192 is located in the inner space of the drawer 190, which is closer to the drawer side wall 191, and the other side of the mating part 192 is located on the outer side of the drawer side wall 191.

[0435] The mating part 192 is detachably connected to at least one of a flexible hose and an electrical wire. For example, the mating part 192 is detachably connected to at least one of a water supply pipe connection for connecting to a water supply pipe, a drain pipe connection for connecting to a drain pipe, an exhaust pipe connection for connecting to a steam exhaust pipe for venting air from inside the drawer 190, and a power supply connection for connecting to a power source.

[0436] At this time, the water supply pipes for the rag washing unit 160 and the water supply pipes connected to an external water source can be connected to both sides of the water supply pipe connection. In addition, the drain pipes for the rag washing unit 160 and the drain pipes connected to the upstream 25b of the U-shaped bend of the kitchen cabinet 2 can be connected to both sides of the drain pipe connection.

[0437] That is, the mating part 192 of this utility model can be a structure in which the water supply pipe and the drain pipe for direct drainage using the water supply and drain pipe provided by the kitchen cabinet 2 are detachably connected to the water supply pipe and the drain pipe inside the robot vacuum base station 100.

[0438] In addition, air exhaust pipes connected to the air outlet 172b of the cloth drying unit 170 can be respectively connected to both sides of the exhaust pipe connection.

[0439] Therefore, the air discharged from the cloth drying section 170 can be discharged downstream 25c of the U-shaped bend.

[0440] Alternatively, the power connection section can be connected to an external power source by attaching a wire. In this case, the wire can be directly attached to the power connection section, or a wire connection device such as a connector or adapter can be used to attach the wire.

[0441] Drawer guide rails 193 are disposed on the drawer side wall 191 and can guide the movement of the drawer side wall 191. Drawer guide rails 193 can be fixedly attached to or integrally formed on the drawer side wall 191, and can be combined with guide rails provided on the outer wall 111 of the cover 110 to guide the movement path of the drawer side wall 191. On the other hand, although this utility model describes the presence of guide rails in the drawer 190 and the cover 110, it is not necessarily limited to the form of guide rails; it can include all forms that can replace guide rails, such as rollers, guide grooves, or guide ribs.

[0442] Control Structure

[0443] exist Figure 27 The present invention discloses a block diagram illustrating the control configuration in a robot vacuum cleaner base station for illustrating embodiments of the present invention.

[0444] Reference Figure 27 The control configuration of the sweeping robot base station 100 of this utility model is described below.

[0445] The robot vacuum cleaner base station 100 of this utility model embodiment also includes a control unit 300 comprising a control placement unit 120, a dust collection motor 145, a cloth washing unit 160, and a cloth drying unit 170.

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

[0447] The control unit 300 can sense the approach of the robotic vacuum cleaner 200 and control the door drive unit 126a to rotate the door 126.

[0454] The control unit 300 can control the cloth washing unit 160.

[0455] Specifically, the control unit 300 can control the detergent pump 161d. The control unit 300 can activate the detergent pump 161d to dispense detergent stored in the detergent tank 163 into the dishcloth 242.

[0456] In addition, the control unit 300 can control the regulator 162. The control unit 300 can activate the regulator 162 to adjust the amount of clean water dispensed into the cloth 242.

[0457] In addition, the control unit 300 can control the drain pump 168. The control unit 300 can activate the drain pump 168 to discharge the wastewater after washing the rag 242.

[0458] The control unit 300 can control the cloth drying unit 170.

[0459] Specifically, the control unit 300 can control the heater 171d. The control unit 300 can activate the heater 171d to heat the air expelled to the cloth 242.

[0460] In addition, the control unit 300 can control the air supply fan 171e. The control unit 300 can make the air supply fan 171e operate to expel air into the rag 242.

[0461] In addition, the control unit 300 can control the exhaust fan 173. The control unit 300 can activate the exhaust fan 173 to discharge the air after the cloth 242 has been dried to the outside.

[0462] In addition, the control unit 300 can receive signals from the temperature sensor 174. The control unit 300 can measure the temperature of the air inside the enclosure 110 using the temperature information received from the temperature sensor 174. Furthermore, the control unit 300 can control the operation of the heater 171d based on the temperature information received from the temperature sensor 174 to sterilize bacteria present in the cloth 242.

[0463] Reference Figures 28 to 43 The following describes another embodiment of the sweeping robot base station of this utility model.

[0464] To avoid repetitive description, in this embodiment, except for the specifically described components, the structure and effects are the same as those of a sweeping robot base station of an embodiment of the present invention, and therefore can be referenced thereto.

[0465] In another embodiment of the sweeping robot base station of this utility model, the cleaning plate 1122 is a structure for cleaning the mop of the sweeping robot 200, and can be placed on the upper side of the cleaning tank 1128 of the base 1121. In addition, the cleaning plate 1122 can contact the mop 242 when the sweeping robot 200 is placed on it.

[0466] The cleaning plate 1122 can be a plate that is generally inclined downwards towards the center.

[0467] Specifically, the cleaning plate 1122 includes a flow guiding surface 1122c formed in a curved shape. Furthermore, at least one through-hole 1122b through which fluid can pass can be formed in the flow guiding surface 1122c. Additionally, cleaning protrusions 1122a may be formed protruding from the flow guiding surface 1122c.

[0468] The fluid discharged into the cleaning plate 1122 can be guided to flow through the through hole 1122b.

[0469] With this configuration, the flow of washing water and / or air is guided by the flow guide surface 1122c and can leak through the through hole 1122b into the space formed between the washing plate 1122 and the washing tank 1128. Thus, heated air can be supplied to the washing tank 1128 through the through hole 1122b.

[0470] On the other hand, in this embodiment, at least a portion of the cleaning plate 1122 may be disposed on the upper side of the flow path separation section 1128c, which will be described later. That is, in this embodiment, the cleaning plate 1122 may also include a return flow path cover 1122d, which protrudes upward from the flow guide surface 1122c and is combined with the upper side of the flow path separation section 1128c.

[0471] In this embodiment, the cleaning plate 1122 can be formed in a shape corresponding to the shape of the flow path separation section 1128c. For example, the front left side portion of the cleaning plate 1122 can be formed by protruding upward from the flow guide surface 1122c, thereby covering the lower flow path separation section 1128c.

[0472] With this configuration, the cleaning plate 1122 and the cleaning tank 1128 can be accurately combined, while providing sufficient space to form the return flow path 1125a.

[0473] On the other hand, the cleaning tank 1128 is a structure for placing the cleaning plate 1122. The cleaning tank 1128 can be disposed on the rear side of the base body 1121a. The cleaning tank 1128 is disposed on the lower side of the cleaning plate 1122 and is detachably connected to the cleaning plate 1122. The cleaning tank 1128 can be formed correspondingly to the cleaning plate 1122 so that the cleaning plate 1122 can be inserted. Liquid passing through the cleaning plate 1122 can flow into the cleaning tank 1128.

[0474] The cleaning tank 1128 may include a cleaning tank base surface 1128a for fluid flow through the cleaning plate 1122 and a cleaning tank wall 1128b extending vertically from the outer contour of the cleaning tank base surface. The cleaning tank base surface 1128a can be positioned further back from the robot vacuum cleaner base station 100, with a lower height from the ground (kitchen floor). This allows the fluid flowing through the cleaning plate 1122 to be concentrated at the rear of the cleaning tank 1128 and discharged to the outside through the wastewater inlet 164c.

[0475] In this embodiment, a flow path separation section 1128c may be formed in the cleaning tank 1128. The flow path separation section 1128c may be formed by protruding upward from the base surface 1128a of the cleaning tank and forming a return flow path 1125a on the lower side. Specifically, a return flow path 1125a may be formed between the lower side of the base 1121 and the flow path separation section 1128.

[0476] On the other hand, in this embodiment, the dust collection unit 1140 includes: a dust collection unit cover 1141, a filter 1142, a dust bag 1143, a dust bag drawer 1144, a dust collection motor 1145, a dust collection motor cover 1146, a first dust collection flow path 1147, and a second dust collection flow path 1148.

[0477] The dust collection unit cover 1141 can form a space inside that can accommodate the dust bag 1143, the filter 1142, and the dust bag drawer 1144.

[0478] The dust collection unit cover 1141 can be internally pulled out and combined with a dust bag drawer 1144, in which a dust bag 1143 can be stored.

[0479] Dust inside the dust bin 220 can flow into the dust collection unit cover 1141.

[0480] On the other hand, in this embodiment, one side of the interior of the dust collection cover 1141 can be connected to the first dust collection flow path 1147, and the other side can be connected to the second dust collection flow path 1148. In addition, when the dust bag 1143 is combined with the dust collection cover 1141, the dust bag 1143 can be connected to the first dust collection flow path 1147 inside the dust collection cover 1141.

[0481] Specifically, the dust collection section cover 1141 may have an inlet 1141a communicating with the first dust collection flow path 1147 and an outlet 1141b communicating with the second dust collection flow path 1148.

[0482] At this time, the inlet 1141a can be positioned higher than the outlet 1141b. Thus, the air and dust flowing in through the inlet 1141a flow downwards, and after the dust is captured by the dust bag 1143, it can be discharged through the outlet 1141b. During this process, since the air flows from top to bottom, it effectively prevents air from flowing upwards or dust from scattering upwards.

[0483] On the other hand, in this embodiment, the outlet 1141b can be positioned forward of the inlet 1141a. For example, the inlet 1141a can be formed on the rear side of the dust collection shroud 1141, and the outlet 1141b can be formed on the lower side of the dust collection shroud 1141. In this case, the outlet 1141b can be positioned further forward of the front side of the dust collection shroud 1141 than the rear side of the dust collection shroud 1141.

[0484] On the other hand, in this embodiment, the outlet 1141b can be formed by combining the dust collection cover 1141 with the dust bag drawer 1144. In this case, the outlet 1141b of the dust collection cover 1141 and the outlet 1144c of the dust bag drawer 1144 can refer to the same space.

[0485] On the other hand, a sterilization module 1150 can be integrated into the dust collection hood 1141. For example, a hot air inlet for hot air flowing from the sterilization module 1150 and a hot air exhaust outlet for hot air can be formed in the dust collection hood 1141. In this case, the hot air inlet and the hot air exhaust outlet can be formed on the rear side of the dust collection hood 1141, and can be respectively arranged on the left and right sides of the rear side of the dust collection hood 1141. Furthermore, the hot air inlet can be arranged closer to the ground than the hot air exhaust outlet. That is, the hot air inlet and the hot air exhaust outlet can be arranged at opposite corners on the rear side of the quadrilateral-shaped dust collection hood 1141. This allows the flow path of the hot air to be maximized.

[0486] As another example, a sterilization module 1150 that irradiates light into the interior of the dust collection unit 1141 can be attached to the upper side of the dust collection unit shroud 1141. In this case, the light can be ultraviolet light (UV-C).

[0487] On the other hand, in this embodiment, the dust collection unit cover 1141 may also include a gasket that makes the internal space of the dust collection unit cover 1141 airtight when the dust bag drawer 1144 is introduced.

[0488] The filter 1142 can be installed in the dust bag drawer 1144. Specifically, the filter 1142 can be installed inside the dust bag drawer 1144 and pulled out together with the dust bag drawer 1144.

[0489] On the other hand, the filter 1142 can be configured to be lower than the inlet 1141b with reference to the bottom surface of the dust bag drawer body 1141a. The filter 1142 can be configured to be positioned forward of the outlet 1144c of the dust bag drawer 1144.

[0490] Specifically, the filter 1142 can be detachably attached to the lower side of the dust bag drawer 1144. In this case, the filter 1142 can be positioned at the longitudinal (front) end of the flow path separation section 1144e. Therefore, the filter 1142 can be positioned between the handle of the dust bag drawer 1144 and the flow path separation section 1144e. That is, the filter 1142 can be positioned adjacent to the front of the dust bag drawer 1144.

[0491] The filter 1142 can be pulled out together with the dust bag drawer 1144 when the dust bag drawer 1144 is pulled out.

[0492] The filter 1142 can be positioned below the dust bag 1143. In this case, the dust bag 1143 can be detachably attached to the dust bag drawer 1144 in a sliding manner along the vertical direction.

[0493] Therefore, the dust bag 1143 can be separated vertically from the dust bag drawer 1144 when the dust bag drawer 1144 is pulled out, and the filter 1142 can be exposed to the outside when the dust bag 1143 is separated.

[0494] On the other hand, the filter 1142 includes a filter body 1142a and a protrusion 1142b. A filter element may be built into the filter body 1142a, which is capable of filtering foreign objects from the air discharged after flowing through the internal space of the dust bag 1143 and the dust bag drawer 1144. For example, the filter element may be a pre-filter. Thus, the filter 1142 can prevent foreign objects from entering the dust collection motor 1145 and damaging it.

[0495] The filter body 1142a can be placed on the lower side of the dust bag drawer 1144 and positioned immediately in front of the outlet 1144c.

[0496] At this time, the filter body 1142a can be formed to slope upwards more and more from one side of the length direction to the other. For example, the filter body 1142a can be formed to slope upwards more and more towards the rear. That is, the height between the rear end (the other end in the length direction) of the filter body 1142a and the lower side of the dust bag drawer 1144 can be greater than the height between the front end (one end in the length direction) of the filter body 1142a and the lower side of the dust bag drawer 1144.

[0497] At this time, the height of the rear end of the filter body 1142a can be formed to correspond to the height of the flow path separation section 1144e. For example, the height of the rear end of the filter body 1142a can be the same as the height of the flow path separation section 1144e.

[0498] Therefore, sufficient suction can be provided for air flowing in from the front of the filter 1142 and air flowing in from the top of the filter 1142. At the same time, it has the advantage of being able to filter all air flowing in from various directions.

[0499] On the other hand, if the outlet 1144c is located on the lower side of the dust bag drawer 1144 adjacent to the dust bag 1143, adsorption may occur due to its relationship with the dust bag 1143 located immediately above it.

[0500] To solve this problem, in this invention, adsorption can be prevented by forming a protrusion 1142b in the filter 1142.

[0501] The protrusion 1142b can be formed in a grid pattern protruding from the filter body 1142a toward the dust bag 1143. Specifically, the protrusion 1142b can be formed as a plurality of ribs protruding upward from the filter body 1142a and intersecting each other. Specifically, the protrusion 1142b can include a first protrusion 1142ba formed along the length direction (front-back direction) and a second protrusion 1142bb formed along the direction intersecting the first protrusion 1142ba (left-right direction).

[0502] At this time, based on the state where the filter 1142 is installed, the maximum height of the protrusion 1142b can be the same as the maximum height of the filter body 1142a.

[0503] On the other hand, the filter 1142 may also include a mounting groove 1142c. The mounting groove 1142c can be recessed upward from the lower side of the filter body 1142a. Therefore, when the lower side of the dust bag drawer 1144 is provided with a protrusion or member (not shown) for engaging with the filter 1142, it can engage with the mounting groove 1142c. In addition, since the mounting groove 1142c can guide the installation position of the filter 1142, it has the advantage that the user or operator can easily identify the installation position of the filter 1142.

[0504] Additionally, a fixing portion 1142d may be formed on the filter body 1142a from the mounting groove 1142c upward. The fixing portion 1142d may be configured to communicate with the mounting groove 1142c.

[0505] The dust bag 1143 refers to a dust bag that collects dust sucked into the dust bin 220 of the robotic vacuum cleaner 200 using the dust collection motor 1145. The dust bag 1143 is detachably attached to the dust collection unit cover 1141. The dust bag 1143 can be stored in the dust bag drawer 1144 and is detachably attached to the dust collection unit cover 114. Therefore, the dust bag 1143 can be separated from the dust collection unit cover 1141 and disposed of.

[0506] The dust bag 1143 may have an inlet for the inflow of dust-containing air. This inlet may communicate with the inlet 1141a of the dust collection shroud 1141 and the inlet 1144b of the dust bag drawer 1144. Therefore, air and dust flowing into the inlet 1141a of the dust collection shroud 1141 can flow into the interior of the dust bag 1143.

[0507] On the other hand, the dust bag 1143 can be configured such that when suction is applied by the dust collection motor 1145, the volume increases while dust is contained inside.

[0508] Therefore, the dust bag 1143 can be made of a material that allows air to pass through but not foreign objects such as dust. For example, the dust bag 1143 can be made of non-woven fabric and can have a hexahedral shape that corresponds to the shape of the dust bag drawer 1144 when the volume increases.

[0509] The dust bag drawer 1144 is attached to the dust collection unit cover 1141 in a pull-out manner, and the dust bag 1143 can be accommodated inside.

[0510] The dust bag drawer 1144 includes a dust bag drawer body 1144a, an inlet 1144b, an outlet 1144c, a handle 1144d, and a flow path separation part 1144e.

[0511] The dust bag drawer body 1144a provides internal space for assembling the dust bag 1143. For example, the dust bag drawer body 1144a can be formed as a box with an open top, and an inlet 1144b can be formed on the rear side to communicate with the first dust collection path 1147. In this case, the inlet 1144b can communicate with the inlet 1141a of the dust collection unit cover 1141.

[0512] The upper side of the dust bag drawer body 1144a can be connected to the first dust collection path 1147 via the inlet 1144b. The inlet 1144b can be a structure that guides the air flowing in the first dust collection path 1147 into the interior of the dust bag 1143. The inlet 1144b can connect the first dust collection path 1147 with the dust bag 1143. Therefore, dust sucked in from the dust bin 220 of the robotic vacuum cleaner 200 can move into the interior of the dust bag 1143 through the first dust collection path 1147, the inlet 1141a of the dust collection cover 1141, and the inlet 1144b of the dust bag drawer 1144.

[0513] The dust bag drawer 1144 can communicate with the second dust collection path 1148 through an outlet 1144c formed on its lower side (bottom). The outlet 1144c can be a structure that guides air passing through the dust bag 1143 to the second dust collection path 1148. That is, the outlet 1144c can be formed to communicate with the internal space formed by combining with the bottom surface of the flow path separation section 1144e and the dust collection section cover 1141.

[0514] At this time, the outlet 1144c can be configured at a different height from the inlet 1144b. The outlet 1144c can be configured so that it is lower than the inlet 1144b with the lower side (bottom) of the dust bag drawer 1144 as a reference. The outlet 1144c allows the internal space of the dust bag drawer 1144 to communicate with the second dust collection path 1148. Therefore, air that has been filtered of dust while passing through the dust bag 1143 can move to the second dust collection path 1148 through the outlet 1144c.

[0515] On the other hand, in this embodiment, the outlet 1144c can be configured to be located forward of the inlet 1144b. For example, the outlet 1144c can be configured to be closer to the handle 1144d than the inlet 1144b.

[0516] On the other hand, in this embodiment, the dust bag drawer 1144 forms a flow path for air passing through the dust bag 1143 to be discharged to the dust collection motor 1145. That is, the dust bag drawer 1144 includes a flow path separation section 1144e, which protrudes upward from the bottom surface of the dust bag drawer body 1144a, forming a flow path between the flow path separation section 1144e and the dust collection cover 1141.

[0517] The flow path separation section 1144e can be provided on the lower side of the dust bag drawer body 1144a, and can form at least a part of the second dust collection flow path 1148.

[0518] As an example, such as Figure 31 As shown in the figure, the flow path separation section 1144e can be formed such that a pair of flow path separation sidewalls 1144ea opposite to each other bend upward from the lower side (bottom) of the dust bag drawer body 1144a and are covered by the flow path separation cover wall 1144eb connecting the pair of flow path separation sidewalls 1144ea.

[0519] As another example, such as Figure 35b As shown in the figure, the flow path separation section 1144e can be formed such that a pair of flow path separation sidewalls 1144ea opposite to each other protrude downward from the lower side (bottom) of the dust bag drawer body 1144a and are covered by the flow path separation cover wall 1144eb connecting the pair of flow path separation sidewalls 1144ea.

[0520] As another example, such as Figure 35c As shown in the figure, the flow path separation section 1144e can be formed in the following form: a pair of flow path separation sidewalls 1144ea opposite to each other protrude downward from the lower side (bottom) of the dust bag drawer body 1144a, and the lower ends of the pair of flow path separation sidewalls 1144ea are open.

[0521] As another example, such as Figure 35d As shown in the figure, the flow path separation section 1144e can be formed as follows: the flow path separation side wall 1144ea protrudes upward from the lower side (bottom) of the dust bag drawer body 1144a, and the flow path separation cover wall 1144eb bends and extends from the upper end of the flow path separation side wall 1144ea, and is connected to the side wall of the dust bag drawer body 1144a.

[0522] As another example, such as Figure 35e As shown in the figure, the flow path separation section 1144e can be formed as follows: the flow path separation side wall 1144ea extends upward from the lower side (bottom) of the dust bag drawer body 1144a, and the flow path separation cover wall 1144eb extends upward from the upper end of the flow path separation side wall 1144ea and is connected to the side wall of the dust bag drawer body 1144a.

[0523] Thus, at least a portion of the second dust collection flow path 1148 can be formed by being surrounded by the flow path separation sidewall 1144ea, the flow path separation cover wall 1144eb, and the dust collection section cover 1141.

[0524] On the other hand, the flow path separation section 1144e can be formed along the length direction of the dust bag drawer 1144. In this case, a discharge port 1144c can be formed at one end of the flow path separation section 1144e along its length. That is, a discharge port 1144c can be formed at the front end of the second dust collection flow path 1148. On the other hand, the other end of the flow path separation section 1144e along its length can be connected to the rear side of the dust bag drawer body 1144a.

[0525] Therefore, the air flowing into the outlet 1144c can flow backward along the length of the flow path separator and be discharged to the dust collection motor 1145.

[0526] On the other hand, the remaining part of the second dust collection flow path 1148 may be the space formed by the combination of the dust collection motor support 1146c and the lower cover 1146b of the dust collection motor, which will be described later.

[0527] Therefore, in this embodiment, the first dust collection flow path 1147 and the second dust collection flow path 1148 can be formed at different heights. That is, the first dust collection flow path 1147 and the second dust collection flow path 1148 can be configured in a stacked structure. In this case, the second dust collection flow path 1148 can be configured to be lower than the first dust collection flow path 1147. That is, at least a portion of the first dust collection flow path 1147 can be configured above the second dust collection flow path 1148.

[0528] Meanwhile, the first dust collection path 1147 and the second dust collection path 1148 can be formed on different surfaces of the dust collection cover 1141. For example, the first dust collection path 1147 can be formed on the rear side of the dust collection cover 1141, and the second dust collection path 1148 can be formed along the lower side of the dust collection cover 1141.

[0529] Therefore, the second dust collection path 1148 can pass through the lower side of the inlet 1141a.

[0530] Therefore, the air flowing in from the upper rear side of the dust bag drawer 1144 flows towards the lower front side of the dust bag drawer 1144 as it passes through the dust bag 1143. As a result, the dust-containing air can be evenly diffused inside the dust bag 1143, preventing dust from accumulating in specific locations within the dust bag 1143.

[0531] By configuring multiple flow paths in a near-horizontal direction, the overall height can be reduced while stacking them to minimize the lateral width and overall volume of the robot vacuum base station 100.

[0532] On the other hand, a handle 1144d may be provided on the front of the dust bag drawer body 1144a. The handle 1144d may be configured to be gripped by a user. As an example, the handle 1144d may be a recessed groove formed from the front to the rear of the dust bag drawer body 1144a. As another example, the handle 1144d may include: a pair of connecting parts that are hinged to the front of the dust bag drawer body 1144a; and a gripping part that connects the pair of connecting parts, allowing the user to grip it.

[0533] Therefore, according to this utility model, the user can easily pull the dust bag drawer 1144 forward, and then lift the dust bag 1143 upward to remove and replace it.

[0534] On the other hand, in this embodiment, a gasket 1144f may also be provided in the dust bag drawer 1144. The gasket 1144f can provide an airtight seal for the gap formed between the dust collection unit cover 1141 and the dust bag drawer 1144 when the dust bag drawer 1144 is introduced into the dust collection unit cover 1141.

[0535] The washer 1144f can be disposed around the front end of the dust bag drawer 1144. Specifically, a handle 1144d is disposed at the front end of the dust bag drawer 1144, and the washer 1144f can be disposed around the front side of the dust bag drawer 1144 surrounding the handle. In this case, the washer 1144f can be disposed in a position further forward than the dust bag 1143.

[0536] With this configuration, when the dust bag drawer 1144 is introduced into the dust collection unit cover 1141, the internal space of the dust bag drawer 1144 can be sealed to its external space. In this state, when the dust collection motor 1145 is activated, the suction force of the dust collection motor 1145 creates a negative pressure inside the dust bag drawer 1144, which can collect the air and dust inside the dust bin 220.

[0537] On the other hand, Figure 38 and Figure 39 The figure shows an exploded perspective view of the motor housing in a robot vacuum cleaner base station, illustrating another embodiment of the present invention. Figure 40 The figure shows a cross-sectional view illustrating the configuration of the motor housing and flow path in a robotic vacuum cleaner base station according to another embodiment of the present invention. Figure 41 The figure shows a perspective view of a motor shock absorber in a robot vacuum cleaner base station, which is used to illustrate another embodiment of the present invention.

[0538] Reference Figures 38 to 41 The dust collection section 1140 may also include a dust collection module. The dust collection module is capable of providing suction airflow to the dust collection flow path.

[0539] Specifically, the dust collection unit 1140 may also include a dust collection motor 1145 and a dust collection motor cover 1146.

[0540] The dust collection motor 1145 can generate suction in the dust collection flow paths 1147 and 1148. That is, the dust collection motor 1145 can provide suction to draw dust from the dust bin 220 into the dust bag 1143 disposed in the dust collection unit cover 1141.

[0541] The dust collection motor 145 can be configured behind the dust collection unit cover 141. Thus, the dust collection motor 145 can provide suction power to suck up dust from the dust bin 220 of the robot vacuum cleaner 200.

[0542] The dust collection motor 1145 is capable of generating suction by rotation. As an example, although not shown, the dust collection motor 1145 may include a rotor and a stator that rotate relative to each other when a power source is applied, and may include an impeller that rotates about a rotation axis as the rotor rotates. Therefore, suction can be generated by the rotation of the impeller.

[0543] One side of the dust collection motor 1145 can be connected to the second dust collection flow path 1148, and the other side can be connected to the return flow path 1125a. When the dust collection motor 1145 is driven, the air flowing in the second dust collection flow path 1148 can flow into the interior of the dust collection motor housing 1146. In addition, the air flowing into the interior of the dust collection motor housing 1146 can flow in the return flow path 1125a after passing through the dust collection motor 1145.

[0544] On the other hand, in this embodiment, the rotation axis of the dust collection motor 1145 can be configured in the vertical direction. In this case, the horizontal space occupied by the dust collection motor 1145 can be minimized.

[0545] On the other hand, when the rotating shaft of the dust collection motor 1145 is arranged in a vertical direction, it can be configured such that the height of the air flowing into the dust collection motor 1145 is different from the height of the air exiting the dust collection motor 1145. Thus, the structure of the dust collection motor cover 1146 can be formed.

[0546] The dust collection motor housing 1146 can internally house the dust collection motor 1145. The dust collection motor housing 1146 can be positioned behind the dust collection section housing 1141. Alternatively, the dust collection motor housing 1146 can be positioned behind the first dust collection flow path 1147. Additionally, the dust collection motor housing 1146 can be positioned behind the second dust collection flow path 1148.

[0547] That is, taking the front-to-back direction of the robotic vacuum cleaner base station 100 as a reference, the dust collection cover 1141 can be positioned at the front, and the first dust collection flow path 1147 and the second dust collection flow path 1148 can be positioned behind the dust collection cover 1141. Furthermore, the dust passage 1123a can be positioned further back than the first dust collection flow path 1147, and the dust collection motor cover 1146 can be positioned further back than the second dust collection flow path 1148. Additionally, the dust collection motor cover 1146 can be positioned further back than the dust passage 1123a.

[0548] Therefore, the dust collection unit 1140 is configured along the front-rear direction of the robot vacuum base station 100, thereby reducing the overall height.

[0549] In this embodiment, the dust collection motor cover 1146 includes an upper dust collection motor cover 1146a, a lower dust collection motor cover 1146b, a dust collection motor support 1146c, and a motor shock absorber 1146d.

[0550] At this time, the dust collection motor 1145 can be disposed on the dust collection motor support 1146c, the upper dust collection motor cover 1146a is attached to the upper side of the dust collection motor support 1146c, and the lower dust collection motor cover 1146b can be disposed on the lower side of the dust collection motor 1145. On the other hand, a motor shock absorber 1146d can be attached between the dust collection motor support 1146c and the upper dust collection motor cover 1146b.

[0551] With this configuration, the dust collection motor 1145 can be placed on the dust collection motor support 1146c, the motor shock absorber 1146d can be combined, the upper cover 1146a of the dust collection motor can be assembled, and the lower cover 1146b of the dust collection motor can be assembled on the lower side of the cover 1110.

[0552] Therefore, the components of the dust collection motor housing 1146 can be assembled from the upper and lower sides of the dust collection motor 1145, thus making assembly and repair operations easy.

[0553] The upper cover 1146a of the dust collection motor can cover the upper side of the dust collection motor 1145. The upper cover 1146a of the dust collection motor may include: a motor receiving part 1146aa, which receives a portion of the upper side of the dust collection motor 1145; and an upper flow path separation part 1146ab, which is connected to the motor receiving part 1146aa and forms a flow path inside.

[0554] The motor housing 1146aa can be formed in a cylindrical shape and can be closed at the top. In this case, the diameter of the inner circumferential surface of the motor housing 1146aa can be larger than the diameter of the outer circumferential surface of the opposing dust collection motor 1145. As a result, the air discharged from the dust collection motor 1145 can flow in the space between the motor housing 1146aa and the dust collection motor 1145, and can be discharged to the upper flow path separation section 1146ab.

[0555] The upper flow path separation section 1146ab can be formed by extending outward in a radial direction from the outer peripheral surface of the motor housing 1146aa. Specifically, the upper flow path separation section 1146ab can be formed by an upper surface and a pair of side surfaces. In this case, at least one of the side surfaces of the upper flow path separation section 1146ab can be formed by extending tangentially from the outer peripheral surface of the motor housing 1146aa and then forming a bent shape. This allows the flow direction of the air discharged between the motor housing 1146aa and the dust collection motor 1145 to be guided. In addition, the upper surface of the upper flow path separation section 1146ab is formed horizontally in a manner that covers the upper side of the pair of side surfaces, and can be formed with a groove to accommodate at least a portion of the pipe or hose forming the first dust collection flow path 1147.

[0556] With this configuration, at least a portion of the first dust collection flow path 1147 can pass through the upper side of the upper flow path separation section 1146ab.

[0557] The upper flow path separation section 1146ab can form at least a portion of the return flow path 1125a internally. Specifically, the space formed by the combination of the upper flow path separation section 1146ab and the dust collection motor support section 1146c can form a portion of the return flow path 1125a.

[0558] The lower cover 1146b of the dust collector motor can cover the lower side of the dust collector motor 1145. The lower cover 1146b of the dust collector motor can be attached to the lower side of the drawer 1190. The lower cover 1146b of the dust collector motor may include: a lower cover 1146ba, disposed on the lower side of the dust collector motor 1145; and a lower flow path separation part 1146bb, connected to the lower cover 1146ba, forming a flow path for air flowing into the dust collector motor 1145.

[0559] The lower cover 1146ba can be formed in the shape of a circular plate, with the center of the circle protruding towards the dust collection motor 1145. With this configuration, the upward flow of air flowing into the dust collection motor 1145 can be guided.

[0560] The lower flow path separation section 1146bb can be formed by extending outward in a radial direction from the lower cover section 1146ba. Specifically, the lower flow path separation section 1146bb can be formed as a plate extending outward in a radial direction from the lower cover section 1146ba. In this case, the lower flow path separation section 1146bb can be formed in a shape that bends at a predetermined angle on the same plane after extending outward in a radial direction from the lower cover section 1146ba. In addition, ribs for guiding airflow can be formed by protruding upward in the lower flow path separation section 1146bb along its length. As a result, the airflow flowing from the dust collection unit cover 1141 into the dust collection motor 1145 can be guided.

[0561] The lower flow path separation section 1146bb can form at least a portion of the second dust collection flow path 1148 internally. Specifically, the space formed by the lower flow path separation section 1146bb and the dust collection motor support section 1146c can form a portion of the second dust collection flow path 1148.

[0562] The dust collection motor support 1146c can support the dust collection motor 1145.

[0563] The dust collection motor support 1146c can be connected to various components forming the internal structure of the robotic vacuum cleaner base station 1100. For example, the dust collection motor support 1146c can be connected to the dust collection unit cover 1141. As another example, the dust collection motor support 1146c can be connected to the inner wall 124 or the connecting wall 123 of the mounting part 120. Thus, the dust collection motor support 1146c can provide a supporting force capable of supporting the dust collection motor 1145.

[0564] The dust collection motor support 1146 can be combined with the upper dust collection motor cover 1146a and the lower dust collection motor cover 1146b to form a return flow path 1125a and a second dust collection flow path 1148, respectively. At this time, the dust collection motor support 1146 is combined between the upper dust collection motor cover 1146a and the lower dust collection motor cover 1146b, thus dividing the return flow path 1125a and the second dust collection flow path 1148. Specifically, the second dust collection flow path 1148 can be formed on the lower side of the dust collection motor support 1146c, and the return flow path 1125a can be formed on the upper side of the dust collection motor support 1146c.

[0565] Therefore, multiple flow paths can be stacked on top of each other to maximize space efficiency within a limited height.

[0566] As a result of this configuration, air flowing in from inside the dust bin 220 can flow into the dust collection motor 1145 through the space between the dust collection motor support 1146c and the lower dust collection motor cover 1146b, and then be discharged by the dust collection motor 1145 to the space between the dust collection motor support 1146c and the upper dust collection motor cover 1146a.

[0567] Therefore, the internal space of the dust collection motor cover 1146 can be connected to the second dust collection flow path 1148, and the internal space of the dust collection motor cover 1146 can be connected to the return flow path 1125a.

[0568] Therefore, according to this invention, the dust collection motor 1145 can be arranged vertically, and two separate flow paths are formed by the dust collection motor support 1146. Thus, by stacking the flow paths required for dust collection within a limited height and lateral space, air can flow in and out using these stacked flow paths, thereby maximizing space efficiency.

[0569] The motor shock absorber 1146d is combined between the dust collection motor support 1146c and the dust collection motor 1145, and can elastically support the dust collection motor 1145.

[0570] The motor shock absorber 1146d can be connected between the dust collector motor support 1146c and the upper cover 1146a of the dust collector motor. Specifically, the upper side of the motor shock absorber 1146d can be connected to the upper cover 1146a of the dust collector motor, and the lower side of the motor shock absorber 1146d can be connected to the dust collector motor support 1146c. With this configuration, when the dust collector motor support 1146c and the upper cover 1146a of the dust collector motor are connected, the motor shock absorber 1146d is fixed between the dust collector motor support 1146c and the upper cover 1146a of the dust collector motor, thereby ensuring support force.

[0571] On the other hand, the motor shock absorber 1146d can be formed from a flexible material.

[0572] The motor shock absorber 1146d includes a shock absorber part 1146da and a sealing part 1146db.

[0573] The shock absorber section 1146da can be formed radially, and the dust collection motor 1145 can be placed on the upper side. For example, the shock absorber section 1146da can be formed from a hollow disk, and can be formed in a shape that slopes downward toward the center of the circle.

[0574] Furthermore, the shock absorber section 1146da can contact the axially lower side of the dust collection motor 1145. At the same time, the lower side of the shock absorber section 1146da can contact and be supported by the dust collection motor support section 1146c. With this configuration, the shock absorber section 1146da can surround the dust collection motor 1145 while contacting a portion of the axially lower side of the dust collection motor 1145.

[0575] Therefore, according to this utility model, by arranging the dust collection motor 1145 in a vertical direction and providing a shock absorber part 1146da at its lower part, it is possible to reduce the vibration and noise caused by the operation of the dust collection motor 1145.

[0576] The sealing part 1146db extends from the shock absorber part 1146da and can make the dust collection motor support part 1146c and the upper cover 1146a of the dust collection motor airtight.

[0577] The sealing portion 1146db extends outward in the radial direction from the shock absorber portion 1146da and can be formed in a manner corresponding to the shape of the upper cover 1146a of the dust collection motor. For example, the sealing portion 1146db can be formed in the same shape as the lower end of the upper cover 1146a of the dust collection motor, and can be formed in a shape with a horizontal width greater than the thickness of the lower end of the upper cover 1146a of the dust collection motor.

[0578] According to this configuration, when the dust collection motor support 1146c is combined with the upper cover 1146a of the dust collection motor, the sealing part 1146db disposed therebetween can be pressurized by the dust collection motor support 1146c and the upper cover 1146a of the dust collection motor.

[0579] Therefore, according to this utility model, the sealing part 1146db provides an airtight seal for the return flow path 1125a formed between the dust collection motor support part 1146c and the upper cover 1146a of the dust collection motor, thereby preventing air leakage.

[0580] exist Figure 42 The figure shows an enlarged view of the flow path of the dust collection section in a robot vacuum cleaner base station, which is used to illustrate another embodiment of the present invention. Figure 43 The diagram in the middle is for illustration. Figure 28 The sectional view of the BB section is cut off from the flow path of the dust collection section.

[0581] Reference Figure 42 and Figure 43 The return flow path 1125a provides a flow path for the air discharged from the dust collection motor 1145.

[0582] The return flow path 1125a can be formed by the dust collection motor cover 1146 and the base 1121.

[0583] Specifically, one side of the return flow path 1125a can be the space formed by the combination of the dust collection motor support 1146c and the upper cover 1146a of the dust collection motor.

[0584] Alternatively, the other side of the return flow path 1125a can be disposed inside the base body 1121a. For example, the return flow path 1125a can be the space formed between the upper and lower sides of the base body 1121a.

[0585] Therefore, one side of the return flow path 1125a can pass through the dust collection motor cover 1146. Additionally, the other side of the return flow path 1125a can pass through the lower side of the base 1121. Meanwhile, at least a portion of the return flow path 1125a can be positioned lower than the robotic vacuum cleaner 200 placed on the upper side of the base body 1121a.

[0586] The return flow path 1125a can be connected to the flow path of the dust collection motor 1145. One end of the return flow path 1125a can be connected to the internal space of the dust collection motor housing 1146, and the other end of the return flow path 1125a can be connected to the air return port 1125b.

[0587] The return flow path 1125a can be a flow path formed in a direction that intersects the vertical direction. For example, the return flow path 1125a can be a flow path formed in a horizontal direction inside the cover 110.

[0588] At this time, at least a portion of the return flow path 1125a can be positioned lower than the first dust collection flow path 1147. That is, the return flow path 1125a can be configured to pass under the first dust collection flow path 1147. Therefore, the flow directions of the air flowing in the first dust collection flow path 1147 and the air flowing in the return flow path 1125a can intersect each other on the horizontal plane.

[0589] Additionally, at least a portion of the return flow path 1125a can be positioned above the second dust collection flow path 1128. That is, the return flow path 1125a can be configured to pass above the second dust collection flow path 1148.

[0590] Therefore, by arranging the first dust collection path 1147, the second dust collection path 1148, and the return path 1125a vertically (stacked) within a limited height, space efficiency can be maximized.

[0591] The present invention has been described in detail above through specific embodiments, but this is only for the purpose of specific description of the present invention. The present invention is not limited thereto. Obviously, the present invention can be modified or improved by people with conventional knowledge in the art within the technical concept of the present invention.
