Description

Robot vacuum cleaner station

[0001] The present invention relates to a robot vacuum cleaner station, and more specifically, to a built-in robot vacuum cleaner station that, when combined with a robot vacuum cleaner, can collect dust from the dustbin of the robot vacuum cleaner, wash the mop of the robot vacuum cleaner, and dry the mop.

[0002]

[0003] With the recent advancement of industrial technology, robotic vacuum cleaners are being developed that can autonomously drive and clean areas requiring cleaning without user intervention.

[0004] Such a robot vacuum cleaner is equipped with a sensor capable of recognizing the space to be cleaned, an agitator capable of sweeping the floor surface, and a mop capable of wiping the floor surface, and can drive while sucking up dust from the floor surface of the space recognized by the sensor and wiping with the mop.

[0005] Among robot vacuum cleaners, there are dry robot vacuum cleaners capable of sucking up and removing debris scattered on the floor surface, and wet robot vacuum cleaners capable of wiping the floor surface with a mop containing moisture to effectively remove debris attached to the floor surface. Dry robot vacuum cleaners are equipped with a dust bin and suck up debris from the floor surface using the suction power of a suction motor. Wet robot vacuum cleaners are equipped with a water tank, and water contained in the tank is supplied to the mop so that the mop, while containing moisture, wipes the floor surface to effectively remove debris attached to the floor surface. In addition, there are robot vacuum cleaners equipped with both an agitator and a mop.

[0006] The charging dock of a robot vacuum is a device into which a robot vacuum is docked after cleaning, and which supplies power to the battery equipped in the robot vacuum to charge it. The charging dock is equipped with an internal power supply module. The charging dock is equipped with a charging terminal connected to the power supply module, and the robot vacuum is equipped with a corresponding terminal. When the charging terminal and the corresponding terminal come into contact, power is supplied to the battery to charge it.

[0007] Meanwhile, if a robot vacuum cleaner charging dock is placed indoors, it occupies a certain portion of the space. In this case, indoor space efficiency may suffer. Furthermore, problems may arise where users or pets collide with the robot vacuum cleaner while passing by, resulting in injury to the user or pet as well as damage to the robot vacuum.

[0008] In addition, in the case of stations equipped with a dust collection function, there is a limitation in that the increased volume occupied can detract from the interior design.

[0009] Meanwhile, Chinese Utility Model Registration CN 218922468 U discloses a cleaning station in which a robot vacuum cleaner is combined with the lower side of a washing machine to charge the robot vacuum cleaner, collect dust, and clean the mop of the robot vacuum cleaner.

[0010] However, the above vacuum cleaner station has an open space formed below the washing machine through which a robot vacuum can enter, a detergent and water supply device for washing the mop is provided vertically above the space through which the robot vacuum enters, and a dust bag is placed on the side of the space through which the robot vacuum enters.

[0011] In this type of arrangement, the overall height of the vacuum cleaner station increases, which limits its ability to be mounted using the space underneath furniture, including the sink.

[0012] In addition, since the above vacuum cleaner station must be installed below the washing machine, space for installing the washing machine must be provided, and there is a limitation in that an installation space must be provided with a height exceeding that of the washing machine itself, taking into account the height of the vacuum cleaner station as well.

[0013] In addition, since the space for attaching the dust bag is located close to the ground, users have the inconvenience of having to kneel or squat in front of the station to attach the dust bag, and the space for attaching the dust bag is also narrow, so users have the inconvenience of having to put their hands into the station.

[0014] In addition, Chinese Utility Model Registration CN 217338435 U discloses an assembly structure of a dust bag.

[0015] The dust bag mentioned above is configured to be assembled by inserting it using a sliding mechanism.

[0016] However, the dust bag described above discloses only a detachable structure to prevent mere detachment, and does not disclose a structure for the hygiene of the dust bag.

[0017] However, if dust is stored in the dust bag and a long time passes without separate sterilization measures, insects and microorganisms may multiply. In particular, mites such as grain mites are microorganisms that parasitize grains that are not sufficiently dried. If grains are collected in the dust collection unit in a hot and humid environment, they can easily multiply and move along the airflow of the vacuum cleaner station to escape to the outside.

[0018]

[0019] The present invention was created to improve upon the problems of conventional robot vacuum cleaner stations as described above, and aims to provide a robot vacuum cleaner station that can be built into the lower side of a kitchen cabinet without requiring a separate installation space.

[0020] In addition, the purpose is to provide a robot vacuum cleaner station capable of accommodating a robot vacuum cleaner in the lower space of a kitchen cabinet having a predetermined height limit.

[0021] In addition, the purpose is to provide a robot vacuum cleaner station that can automatically collect dust inside the dustbin of the robot vacuum cleaner when combined with it.

[0022] In addition, the purpose is to provide a robot vacuum cleaner station that can maximize the capacity of the dust bag.

[0023] In addition, the purpose is to provide a robot vacuum cleaner station that can check whether the dust bag is attached.

[0024] In addition, the purpose is to provide a robot vacuum cleaner station capable of sterilizing the inside of the dust bag.

[0025]

[0026] To achieve the above-mentioned purpose, a robot vacuum cleaner station according to the present invention comprises: a housing; a seating portion disposed in the housing and to which at least a portion of the robot vacuum cleaner is coupled; and a dust collection unit for collecting dust inside the dust bin of the robot vacuum cleaner; wherein the dust collection unit comprises: a dust collection unit housing; a dust bag drawer coupled to the dust collection unit housing so as to be drawn out along a first direction; and a dust bag detachably coupled to the dust bag drawer along a second direction intersecting the first direction, to which dust inside the dust bin is collected.

[0027] At this time, the dust bag may include: a dust bag body in which dust is collected; and a detachable part that is coupled to the dust bag body and slides to be detachably coupled to the dust bag drawer.

[0028] At this time, an inlet for dust from the dust bin to enter may be formed in the detachable part.

[0029] Meanwhile, the dust collector may include a dust bag detection unit that is provided in the dust collector housing and detects the dust bag.

[0030] At this time, the dust bag detection unit can detect the presence of the dust bag by contacting the attachment / detachment unit.

[0031] Accordingly, when the dust bag drawer is inserted while the dust bag is coupled to the dust bag drawer, the dust bag detection unit can detect the dust bag.

[0032] Meanwhile, the dust bag may include a light-transmitting part that is coupled to the dust bag body and transmits light into the interior of the dust bag body.

[0033] At this time, the light-transmitting part can transmit light including the ultraviolet region.

[0034] In addition, the light-emitting part may be positioned on the upper surface of the dust bag body.

[0035] Meanwhile, the light-emitting part may be formed integrally with the detachable part.

[0036] At this time, the light-emitting part and the detachable part may be placed on the other side of the dust bag body.

[0037] Meanwhile, the dust bag further includes an air inlet that is coupled to the detachable part with the dust bag body in between; the air inlet includes an inlet pipe that guides dust in the dust container into the dust bag body; and the inlet pipe may be formed along the drawing direction of the dust bag drawer.

[0038] In addition, the air inlet may further include a guide wall that guides the flow direction of the air passing through the inlet pipe.

[0039] At this time, a pair of guide walls may be provided on both sides of the inlet pipe.

[0040] Meanwhile, the air inlet part further includes an inlet plate formed with an inlet pipe formed therein and coupled to the detachable part with the dust bag body in between; and an inlet cover coupled to the inlet plate and opening and closing the inlet pipe; wherein the inlet cover includes a fixed part fixedly coupled to the inlet plate; and an opening / closing part that opens and closes the inlet pipe by the suction force of a dust collection motor; and when the dust bag is coupled to the dust bag drawer, the fixed part may be positioned below the opening / closing part.

[0041] Meanwhile, the first direction mentioned above may be the direction in which the robot vacuum cleaner enters and exits the seating area.

[0042] In addition, the second direction mentioned above may be an up-and-down direction.

[0043]

[0044] As described above, according to the robot vacuum cleaner station of the present invention, a module capable of charging the robot vacuum cleaner, collecting dust, and washing the mop is arranged along a horizontal direction with respect to the robot vacuum cleaner, thereby providing the effect of utilizing the lower space of the kitchen cabinet.

[0045] In addition, the charging port, dust collection unit, mop washing unit, and mop drying unit are arranged around the robot vacuum cleaner, which has the effect of enabling the robot vacuum cleaner to perform various functions simultaneously.

[0046] In addition, since the sides other than the front are concealed by the kitchen cabinets, it has the effect of providing the user with an aesthetic sense in terms of interior design.

[0047] In addition, by allowing the dust bag to be attached along the vertical direction, the volume occupied by the attachment / detachment structure can be reduced, and the capacity of the dust bag can be increased.

[0048] In addition, by equipping the dust collection housing with a sensor, it is possible to detect the connection when the attachment part of the dust bag is connected.

[0049] In addition, by providing a light-transmitting portion on the upper surface of the dust bag so that light for sterilization can pass through, the inside of the dust bag can be sterilized.

[0122]

[0123] robot vacuum cleaner

[0124]

[0125] Meanwhile, FIGS. 5 to 8 disclose drawings for explaining a robot vacuum cleaner in a robot vacuum cleaner system according to an embodiment of the present invention.

[0126] Referring to FIGS. 5 to 8, the structure of the robot vacuum cleaner (200) is described as follows.

[0127] The robot vacuum cleaner (200) can automatically clean the area to be cleaned by driving itself through the area to be cleaned and sucking up foreign substances such as dust from the floor.

[0128] A robot vacuum cleaner (200) according to an embodiment of the present invention is configured to be placed on a floor and move along the floor surface to clean the floor. Accordingly, the following description will define the up and down directions based on the state in which the robot vacuum cleaner (200) is placed on the floor.

[0129] And based on a pair of wheels (260), the side where the auxiliary wheel (270) to be described later is positioned is designated as the front, and the side where the rotating cleaner (240) to be described later is positioned is designated as the rear.

[0130] The 'lowest part' of each component described in the embodiment of the present invention may be the part located lowest in each component when the robot vacuum cleaner (200) according to the embodiment of the present invention is placed on the floor for use, or the part closest to the floor.

[0131] A robot vacuum cleaner (200) according to an embodiment of the present invention comprises a body (210), a dust bin (220), a water tank (230), a rotating cleaning unit (240), an agitator (250), a wheel (260), an auxiliary wheel (270), and a charging terminal (280).

[0132] The body (210) can form the overall shape of the robot vacuum cleaner (200). Each component forming the robot vacuum cleaner (200) can be combined with the body (210), and some components forming the robot vacuum cleaner (200) can be accommodated inside the body (210).

[0133] Specifically, the body (210) may be equipped with parts of the robot vacuum cleaner (200) in its internal space. For example, the body (210) may accommodate a battery and at least one motor in its internal space.

[0134] In an embodiment of the present invention, the body (210) may be formed in a shape where the width (or diameter) in the horizontal direction is greater than the height in the vertical direction. Such a body (210) helps the robot vacuum cleaner (200) form a stable structure and can provide a structure advantageous for avoiding obstacles while the robot vacuum cleaner (200) moves (drives).

[0135] When viewed from above or below, the body (210) can be made in various shapes, such as circular, elliptical, or square.

[0136] The body (210) can be configured by dividing it into a lower body and an upper body, and the lower body and the upper body can be combined to form a space inside.

[0137] The lower body can be combined with the upper body to form a space capable of accommodating a battery, at least one sensor, and at least one motor inside.

[0138] In the lower body, an intake part (211) into which air is introduced and a hole for accommodating a pair of wheels (260) may be formed.

[0139] The suction part (211) may be a passage through which dust from the bottom surface is introduced. Additionally, the suction part (211) may be in communication with a suction passage (not shown) formed inside the body (210), and the suction passage may be in communication with the internal space of the dust container (220).

[0140] Meanwhile, the lower body may be further provided with an exhaust passage. One side of the exhaust passage may be in communication with the internal space of the dust bin (220), and the other side may be in communication with the exhaust port. At this time, a filter may be placed in the exhaust port.

[0141] With this configuration, air introduced through the intake section (211) flows into the dust bin (220) through the intake path and can be discharged to the exhaust port through the exhaust path.

[0142] An agitator (250), to be described later, can be rotatably accommodated in the suction part (211). With this configuration, dust around the suction part (211) can be guided into the suction part (211) by the rotation of the agitator (250), and the efficiency of dust suction can be increased.

[0143] The upper body can form the upper exterior of the robot vacuum cleaner (200). Although not illustrated, the upper body may be equipped with a display.

[0144] The robot vacuum cleaner (200) of the present invention may include a bumper. The bumper is formed to be attached along the edge of the body (210) and to move relative to the body (210).

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

[0146] The dustbin (220) may be equipped to suck in external dust and air and store dust.

[0147] The dust container (220) can store dust that enters through the suction path. The dust container (220) may have a dust inlet that communicates with the suction path, an internal space for storing dust, and an air outlet for discharging air.

[0148] The dustbin (220) may be provided inside the body (210). At this time, the dustbin (220) may be fixedly connected to the body (210) or, depending on the embodiment, may be provided so as to be detachable.

[0149] Meanwhile, in the present invention, a dust discharge channel may be formed in the dust bin (220). The dust discharge channel may connect the internal space of the dust bin (220) with the external space of the robot vacuum cleaner (200). With such a configuration, when dust is collected through the robot vacuum cleaner station (100), the dust inside the dust bin (220) can be removed.

[0150] Meanwhile, a dust outlet (221) communicating with the dust discharge path may be formed in the dust container (220) according to an embodiment of the present invention. For example, the dust outlet (221) may be formed on one side of the rear of the outer surface (or outer circumference) of the body (210). For another example, the dust outlet (221) may be formed on the outer surface of the dust container (220).

[0151] Additionally, the robot vacuum cleaner (200) according to an embodiment of the present invention may be provided with a dust bin door (222) capable of selectively opening and closing the dust discharge port (221). Specifically, the dust bin door (222) may be coupled to the body (210) and positioned to block the dust discharge port (221). For example, the dust bin door (222) may be formed of a rubber or resin material and configured to be flip-floppy, with one side fixedly coupled to the body (210).

[0152] With this configuration, when the dust collection motor (145) of the robot vacuum cleaner station (100) described later is operated, the dust bin door (222) is elastically deformed by the driving force of the dust collection motor (145), and the dust discharge port (221) is opened so that dust inside the dust bin (220) can be collected into the dust collection unit (140) of the robot vacuum cleaner station (100).

[0153] The water container (230) is formed in the shape of a container having an internal space for storing a liquid such as water. The water container (230) is placed inside the body (210), and may be fixedly connected to the body (210) or detachably connected to the body (210).

[0154] The water tank (230) includes a supply unit (231) and a nozzle (not shown). The supply unit (231) may be provided to supply a liquid, such as water, from the outside. For example, the supply unit (231) may have an inlet formed on the rear side of the outer surface (or outer circumference) of the body (210) and may be connected to a storage space inside the water tank (230) through a water supply hose.

[0155] At this time, the supply unit (231) may be positioned on the opposite side of the left and right direction of the robot vacuum cleaner (200) in relation to the dust outlet (221). For example, if the dust outlet (221) is positioned on the rear left side of the body (210), the supply unit (231) may be positioned on the rear right side of the body (210).

[0156] Through this configuration, the robot vacuum cleaner (200) is coupled to the robot vacuum cleaner station (100), and the robot vacuum cleaner station (100) can simultaneously perform dust collection and water injection.

[0157] Meanwhile, the nozzle (not shown) is formed in the shape of a tube or pipe and is connected to the water tank (230) so that the liquid inside the water tank (230) can flow through it. One end of the nozzle (not shown) is connected to the water tank (230), and the other end is positioned so as to be located on the upper side or on the rotating plate of a pair of rotating plates (241), respectively, thereby allowing the liquid inside the water tank (230) to be supplied to a pair of rags (242) respectively.

[0158] That is, the nozzle (not shown) may be formed in a shape where one tube is branched into two, and in this case, one of the branched ends may be located on the upper side of the left mop, and the other branched end may be located on the upper side of the right mop.

[0159] Meanwhile, although not shown, the water tank (230) is equipped with a pump to allow water inside the water tank (230) to flow through a nozzle (not shown). Therefore, when the pump of the water tank (230) is operated, the liquid stored inside the water tank (230) can be discharged to a rotating cleaner (240) through a nozzle (not shown).

[0160] The rotating cleaning unit (240) includes a rotating plate (241) and a mop (242).

[0161] The rotating plate (241) may be provided as a pair including a left rotating plate and a right rotating plate, and the mop (242) may be provided as a pair including a left mop and a right mop.

[0162] The rotating plate (241) can be rotatably positioned on the bottom surface of the body (210), and the mop (242) can be attached to the lower side.

[0163] The rotating plate (241) is formed to have a predetermined area and is formed in the shape of a flat plate or a flat frame. This rotating plate (241) is generally laid horizontally, and accordingly, is formed in 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 body (210) may be parallel to the bottom surface or may be inclined with respect to the bottom surface. The rotating plate (241) may be formed in the shape of a circular plate, the bottom surface of the rotating plate (241) may generally be circular, and the rotating plate (241) may be formed in a rotationally symmetrical shape overall.

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

[0165] The mop (242) can be attached to the lower side of the rotating plate (241) so as to face the floor.

[0166] The mop (242) is formed such that the bottom surface facing the floor has a predetermined area, and the mop (242) is formed in a flat shape. The mop (242) is formed such that the width (or diameter) in the horizontal direction is sufficiently larger than the height in the vertical direction. When the mop (242) is attached to the body (210), the bottom surface of the mop (242) may be parallel to the floor or may be inclined with respect to the floor.

[0167] The bottom surface of the mop (242) can generally be circular, and the mop (242) can be formed in a rotationally symmetrical shape overall. Additionally, the mop (242) can be attached to the bottom surface of the rotating plate (241) and can be coupled to the rotating plate (241) to rotate together with the rotating plate (241).

[0168] Meanwhile, although not shown, the rotating cleaning unit (240) may be equipped with a driving unit that applies rotational force to the rotating plate (241). For example, the driving unit may be equipped with a motor and at least one gear. Thus, when the driving unit is operated, the rotating plate (241) and the mop (242) rotate to wipe and clean the floor surface.

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

[0170] Meanwhile, the agitator (250) according to the present embodiment may receive rotational power by having a separate agitator motor (not shown) installed, and may also receive rotational power from a driving motor according to the embodiment, and may also receive rotational power from the driving unit of the rotating cleaning unit (240).

[0171] The wheel (260) may be provided on the bottom surface of the body (210) and may be connected to a driving unit (not shown). At this time, the driving unit (not shown) may be coupled to the body (210).

[0172] The wheel (260) is provided on the body (210) and can roll on the floor.

[0173] The wheel (260) may be composed of a first driving wheel and a second driving wheel. In this case, the first driving wheel may be formed identically to the second driving wheel, or may be formed symmetrically. For example, if the first driving wheel is located on the left side of the robot vacuum cleaner (200), the second driving wheel may be located on the right side of the robot vacuum cleaner (200), and in this case, the first driving wheel and the second driving wheel may be symmetrical to each other.

[0174] The drive unit (not shown) may be comprised of a driving motor and a gear. In this case, the driving motor is housed inside the body (210) and can provide power to the wheel (260). The driving motor may include a first driving motor and a second driving motor.

[0175] The driving motor may be an electric motor. Multiple gears are configured to mesh and rotate with each other, connecting the driving motor and the wheel (260) and transmitting the rotational power of the driving motor to the wheel (260). Therefore, the wheel (260) can rotate when the rotation axis of the driving motor rotates.

[0176] With this configuration, when the driving motor is operated, the wheel (260) rotates and the body (210) can travel on the floor at a predetermined driving speed.

[0177] The auxiliary wheel (270) is provided on the lower side of the body (210) and can roll on the floor surface (surface to be cleaned). The auxiliary wheel (270) can support the body (210) on the floor surface together with a pair of wheels (260). 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.

[0178] A suction motor (not shown) can generate a suction force capable of sucking in external dust and air through the suction section (211). For example, the suction motor (not shown) may be an electric motor. External dust and air can be drawn into the suction section (211) by the suction force generated by the suction motor (not shown), and after passing through the suction path, can reach the dust bin (220).

[0179] Although not illustrated, the battery is configured to be coupled to the body (210) and to supply power to other components forming the robot vacuum cleaner (200). The battery can supply power to at least one motor equipped in the robot vacuum cleaner (200). For example, the battery can supply power to the motors equipped in the rotary cleaner (240), the agitator (250), the wheel (260), and the suction motor (not illustrated).

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

[0181] The battery can be charged by an external power source, and for this purpose, a charging terminal (280) for charging may be provided on one side of the body (210). For example, the charging terminal (280) may be positioned on the rear side of the outer surface of the body (210). When the robot vacuum cleaner (200) is connected to the robot vacuum cleaner station (100), the charging terminal (280) can come into contact with the power supply terminal (123b) of the robot vacuum cleaner station (100) to receive power.

[0182]

[0183] Robot vacuum cleaner station

[0184]

[0185] Referring to FIGS. 3 to FIGS. 15, the robot vacuum cleaner station (100) of the present invention is described as follows.

[0186] A robot vacuum cleaner (200) can be accommodated in the robot vacuum cleaner station (100). A robot vacuum cleaner (200) can be attached to the mounting portion (120) of the robot vacuum cleaner station (100).

[0187] The robot vacuum cleaner station (100) may include a housing (110).

[0188] The housing (110) can form the exterior of the robot vacuum cleaner station (100). For example, the housing (110) can be formed in a shape similar to a cuboid including at least one outer wall surface.

[0189] The housing (110) may have a space formed therein to accommodate a seating portion (120), a door portion (130), a dust collection portion (140), a mop washing portion (160), and a mop drying portion (170).

[0190] The housing (110) can be mounted on the lower side of the kitchen cabinet (2). Specifically, the housing (110) can be installed in a mounting space formed between the lower plate (23) of the kitchen cabinet (2) and the floor of the kitchen.

[0191] The housing (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.

[0192] For example, a pair of outer walls (111) may be installed on the lower side of the kitchen cabinet (2) at a predetermined distance. At this time, the housing (110) may further include a bottom surface (112) facing the floor of the kitchen, and the pair of outer walls (111) may be connected through the bottom surface (112). Meanwhile, the housing (110) may further include an upper cover (113) facing the lower plate (23) of the kitchen cabinet (2), and the upper cover (113) may be detachably connected to the upper end of the pair of outer walls (111). Thus, even if foreign matter falls downward from the kitchen cabinet (2), it is possible to prevent the components of the robot vacuum cleaner (200) and the robot vacuum cleaner station (100) from being contaminated. Additionally, the housing (110) may further include a rear surface (115) facing the wall of the building. With this configuration, components of a robot vacuum cleaner station (100) can be accommodated inside the housing (110) (between a pair of outer walls).

[0193] Additionally, a robot vacuum cleaner (200) can be accommodated inside the housing (110). The housing (110) may be arranged such that a pair of outer walls (111) are spaced apart from the maximum horizontal width of the robot vacuum cleaner (200). With this configuration, the robot vacuum cleaner (200) can enter and exit the housing (110).

[0194] At this time, in this embodiment, the robot vacuum cleaner (200) can enter and exit the front of the robot vacuum cleaner station (100). Here, "front" may refer to the direction in which the door (131) is provided relative to the interior of the robot vacuum cleaner station (100).

[0195] Additionally, the rear may refer to the opposite direction from the front relative to the interior of the robot vacuum cleaner station (100). For example, a wall of a building (not shown) may be placed at the rear of the robot vacuum cleaner station (100).

[0196] In addition, when looking forward from inside the robot vacuum cleaner station (100), the left side can be called the left side and the right side the right side.

[0197] That is, the outer wall (111) of the robot vacuum cleaner station (100) can be positioned on the left side and the right side, respectively.

[0198] Accordingly, the upper side of the housing (110) is covered by the kitchen cabinet (2), and the lower side of the housing (110) can be covered by the kitchen floor. Additionally, the left and right sides of the housing (110) are covered by the outer wall but are positioned at the bottom of the kitchen cabinet (2). At this time, the lower part of the kitchen cabinet (2), excluding the robot vacuum cleaner station (100), is finished by a baseboard (26), so that consequently only the front of the housing (110) is exposed to the outside.

[0199] Through this, the robot vacuum cleaner station (100) and the robot vacuum cleaner (200) can be minimized from being exposed to the outside.

[0200] With such a configuration, the robot vacuum cleaner station (100) of the present invention has the effect of providing an aesthetic sense to the user in terms of interior design.

[0201] Meanwhile, the housing (110) may have a space through which a water supply hose connected to a water supply pipe passes, a space through which a drainage hose through which wastewater generated after washing the mop (242) is discharged passes, and a space through which a hose through which moisture generated during the drying process of the mop (242) is discharged passes. For example, a space through which the above hoses can pass may be formed in the outer wall (111) of the housing (110).

[0202]

[0203] layout

[0204]

[0205] A robot vacuum cleaner station (100) according to an embodiment of the present invention is characterized by being installed in the lower space of a kitchen cabinet (2).

[0206] To this end, the robot vacuum cleaner station (100) according to an embodiment of the present invention is characterized by being positioned along a horizontal direction in alignment with the space formed between the lower plate (23) of the kitchen cabinet (2) and the floor of the kitchen.

[0207] Specifically, in the robot vacuum cleaner station (100) according to an embodiment of the present invention, a dust collection unit (140) and / or a mop washing unit (160) may be positioned on the side of the entrance (127).

[0208] At this time, when both the dust collection unit (140) and the mop washing unit (160) are provided, the seating unit (120) may be positioned between the dust collection unit (140) and the mop washing unit (160).

[0209] For example, an entrance (127) and a door (131) may be positioned at the front of the robot vacuum cleaner station (100). Additionally, a seating area (120) to which the robot vacuum cleaner (200) is coupled may be positioned from the entrance (127) to the rear. At this time, a dust collection unit (140) may be positioned from the front of the robot vacuum cleaner station (100) to the rear by a predetermined length. Furthermore, a mop washing unit (160) may also be positioned from the front of the robot vacuum cleaner station (100) to the rear by a predetermined length.

[0210] Accordingly, when looking at the robot vacuum cleaner station (100) from the front outer side of the robot vacuum cleaner station (100), the front of the dust collection unit (140) and / or the front of the mop washing unit (160) may be positioned on the left and right sides of the entrance (127).

[0211] At this time, the dust bag drawer (144) of the dust collection unit (140) may be provided so as to be pulled out to the front of the housing (110). In addition, the detergent container (163) of the mop washing unit (160) may be provided so as to be pulled out to the front of the housing.

[0212] Meanwhile, the rear end of the dust collection housing (141) and the detergent container (163) may be positioned at a predetermined distance from the rear end of the housing (110). Additionally, a dust collection motor (145) may be positioned between the rear end of the dust collection housing (141) and the rear end of the housing (110). With this configuration, the total space occupied by the seating portion (120), the dust collection housing (141), and the dust collection motor (145) within a limited space can be minimized.

[0213] Additionally, at least a portion of a passageway through which washing water for washing the mop (242) can flow may be arranged between the rear end of the housing (110) and the rear end of the detergent container (163). With this configuration, the path through which washing water flows from the water supply pipe can be shortened. Furthermore, within a limited space, the total space occupied by the seating portion (120), the detergent container (163), and the passageway through which washing water flows can be minimized.

[0214] Meanwhile, the robot vacuum cleaner station (100) may have a mop drying section (170) positioned behind the seating section (120). At this time, the mop drying section (170) may be positioned between the rear end of the seating section (120) and the rear end of the housing (110).

[0215] Accordingly, in the robot vacuum cleaner station (100) according to an embodiment of the present invention, a dust collection unit (140) and a mop washing unit (160) are arranged on the left and right sides based on the seating unit (120), and a mop drying unit (170) can be arranged on the rear side.

[0216] That is, in the robot vacuum cleaner station (100) according to an embodiment of the present invention, a dust collection unit (140), a mop washing unit (160), and a mop drying unit (170) can all be arranged within a predetermined distance range from the outer edge of the seating unit (120).

[0217] This has the effect of minimizing flow path loss by shortening the distance between the dust bin (220) and the dust collection unit (140) of the robot vacuum cleaner (200). Additionally, by minimizing the distance between the mop (242) and the mop washing unit (160) of the robot vacuum cleaner (200) and the distance between the mop (242) and the mop drying unit (170) of the robot vacuum cleaner (200), it has the effect of limiting the range where washing water and wastewater from washing are present.

[0218] In addition, by this arrangement, the robot vacuum cleaner station (100) of the present invention can arrange all components within a limited height.

[0219] As a result, the robot vacuum cleaner station (100) according to an embodiment of the present invention may have a dust collection unit (140), a mop washing unit (160), and a mop drying unit (170) arranged on three sides surrounding the seating unit (120), excluding the front side where the robot vacuum cleaner (200) enters. With such arrangement, even in situations where the height in the vertical direction is limited, it is possible to charge the robot vacuum cleaner (200) using a minimum horizontal space, as well as collect dust from the robot vacuum cleaner (200), wash the mop (242), and dry the mop (242).

[0220]

[0221] Settling part

[0222]

[0223] As illustrated in FIGS. 12 to 15, the robot vacuum cleaner station (100) may include a seating portion (120).

[0224] The robot vacuum cleaner (200) and the robot vacuum cleaner station (100) can be physically, electrically, and / or electrically connected through the mounting portion (120).

[0225] The seating portion (120) can be placed inside the housing (110).

[0226] An entrance (127) into which a robot vacuum cleaner (200) is introduced may be formed in front of the seating portion (120). The entrance (127) may refer to a space formed on the front surface of the robot vacuum cleaner station (100).

[0227] The entrance (127) can be formed to a size that allows the robot vacuum cleaner (200) to pass through. That is, the height of the entrance (127) is formed to be greater than the height of the robot vacuum cleaner (200). At this time, the entrance (127) may refer to a space formed upward along a vertical direction from the front end of the base (121) to be described later. Alternatively, the entrance (127) may refer to a hole formed in the door frame (132) to be described later through which the robot vacuum cleaner (200) passes.

[0228] At least one of a dust collection unit (140) and a mop washing unit (160) may be arranged on the left and right sides of the entrance (127). Accordingly, the left and right ends of the entrance (127) may be bordered by the dust collection unit (140) and the mop washing unit (160).

[0229] At this time, the entrance (127) can be opened and closed by the door (131).

[0230]

[0231] The seating portion (120) may include a receiving space (S), a base (121), a connecting wall (123), and an inner wall (124).

[0232] A robot vacuum cleaner (200) can be accommodated in the receiving space (S) of the seating portion (120). For example, the receiving space (S) may refer to a space enclosed by a base (121), a connecting wall (123), and an inner wall (124). For another example, the receiving space (S) may refer to a space enclosed by a base (121), a cleaning plate (122), a connecting wall (123), and an inner wall (124). For yet another example, the receiving space (S) may refer to a space where the robot vacuum cleaner (200) is located while connected to a power supply terminal (123b), or a space where the robot vacuum cleaner (200) is located while the dust bin (220) of the robot vacuum cleaner (200) is connected to a dust passage hole (123a).

[0233] The base (121) is configured to support the robot vacuum cleaner (200) when the robot vacuum cleaner (200) is coupled to the robot vacuum cleaner station (100). The wheel (260) of the robot vacuum cleaner (200) may come into contact with the upper surface of the base (121). Additionally, the auxiliary wheel (270) of the robot vacuum cleaner (200) may come into contact with the upper surface of the base (121).

[0234] The base (121) may include a base body (121a), an inclined portion (121b), a wheel coupling portion (121c), an agitator receiving portion (121d), and a washing tank (128).

[0235] The base body (121a) can form the overall shape of the base (121). An inclined section (121b), a wheel coupling section (121c), an agitator receiving section (121d), and a washing tank (128) may be arranged on the base body (121a).

[0236] The base body (121a) can be formed in a shape where the horizontal length and width are greater than the vertical height. Due to this structure, the robot vacuum cleaner station (100) can be stably supported on the floor surface.

[0237] A recirculation channel may be provided inside the base body (121a). Accordingly, air discharged from the dust collection motor (145) may flow through the recirculation channel (125a) formed inside the base body (121a) and be exhausted to the air recirculation port (125b).

[0238] The inclined section (121b) can be placed at the entrance where the robot vacuum cleaner (200) climbs from the base body (121a).

[0239] The inclined section (121b) may have an upward slope toward the front of the direction in which the robot vacuum cleaner (200) enters. More specifically, the inclined section (121b) may have an upward slope toward the rear, with the front end connected so as not to have a height difference from the ground. That is, the inclined section (121b) may be formed to gradually rise from the ground when the robot vacuum cleaner (200) enters. This allows the robot vacuum cleaner (200) to easily climb from the ground to the robot vacuum cleaner station (100).

[0240] A wheel guide section (121ba) may be provided in the inclined section (121b).

[0241] The wheel guide section (121ba) may be formed in the shape of a groove to guide the movement of the wheel (260) of the robot vacuum cleaner (200). The surface of the wheel guide section (121ba) may be formed to correspond to the surface of the wheel (260) so that the robot vacuum cleaner (200) can drive stably. Additionally, the wheel guide section (121ba) may be formed such that the width of the groove is greater than the width of the wheel (260) at the entrance where the robot vacuum cleaner (200) climbs, and the width of the groove becomes narrower relative to the entrance as it moves forward along the climbing path of the robot vacuum cleaner (200). Thus, the wheel (260) of the robot vacuum cleaner (200) can easily enter the robot vacuum cleaner station (100), but left and right movement is restricted by the groove that gradually narrows, allowing the wheel (260) to be guided to the correct position.

[0242] An auxiliary wheel guide (121bb) may be provided in the inclined section (121b).

[0243] The auxiliary wheel guide portion (121bb) may be formed in a groove shape to guide the movement of the auxiliary wheel (270) of the robot vacuum cleaner (200). Additionally, the auxiliary wheel guide portion (121bb) may be formed in a protruding shape so as to come into contact with the auxiliary wheel (270) when the wheel (260) of the robot vacuum cleaner (200) is seated on the wheel guide portion (121ba). Thus, when the robot vacuum cleaner (200) travels along the inclined portion (121b), it can travel while being stably supported by the auxiliary wheel (270) as well as the wheel (260).

[0244] The wheel (260) of the robot vacuum cleaner (200), which has moved upward along the wheel guide (121ba), can be placed on the wheel coupling portion (121c). When the wheel (260) of the robot vacuum cleaner (200) is placed on the wheel coupling portion (121c), a physical connection between the robot vacuum cleaner (200) and the robot vacuum cleaner station (100) can be achieved. To allow the robot vacuum cleaner (200) to stop stably, the surface of the wheel coupling portion (121c) can be formed to correspond to the surface of the wheel (260). The wheel coupling portion (121c) can be extended from the upper end of the wheel guide (121ba). The wheel coupling portion (121c) can be connected to the wheel guide (121ba) without a step. Thus, the robot vacuum cleaner (200) can easily move past the inclined portion (121b) to the wheel coupling portion (121c).

[0245] The wheel coupling portion (121c) may be positioned at the stopping position of the left and right wheels (260) of the robot vacuum cleaner (200) so that the robot vacuum cleaner (200) stops at the correct position. Here, the stopping position of the wheel (260) means a position determined for the robot vacuum cleaner (200) to stop in order to be connected to the power supply terminal (123b) and / or a position determined for the dust bin (220) of the robot vacuum cleaner (200) to stop in order to be connected to the dust passage hole (123a).

[0246] The shape of the wheel coupling part (121c) can be formed in an arch shape, that is, a shape corresponding to the shape of the wheel (260) of the robot vacuum cleaner (200). Through this configuration, the robot vacuum cleaner (200) can move along the wheel guide part (121ba) and stop as soon as the wheel (260) is inserted into the wheel coupling part (121c), and the wheel (260) can be stably seated on the arch-shaped wheel coupling part (121c).

[0247] At least a portion of the agitator (250) of the robot vacuum cleaner (200) can be accommodated in the agitator receiving portion (121d).

[0248] The agitator receiving portion (121d) may be formed between the wheel coupling portions (121c). The agitator receiving portion (121d) may be formed in a shape corresponding to the agitator (250) of the robot vacuum cleaner (200). The agitator receiving portion (121d) may be formed in a rectangular shape with an open top. The lower surface of the agitator receiving portion (121d) may be sealed by the bottom surface of the base body (121a) or the bottom surface of the housing (110). Accordingly, the agitator (250) of the robot vacuum cleaner (200), which has moved upward along the inclined portion (121b), may be seated in the recessed portion (121da) through the open upper surface of the agitator receiving portion (121d). At this time, the depth of the recessed portion (121da) may be formed shallower than the depth of the wheel coupling portion (121c).

[0249] The agitator receiving portion (121d) can be formed to be recessed from the base body (121a). In this way, when the wheel (260) of the robot vacuum cleaner (200) is seated on the wheel coupling portion (121c), the agitator receiving portion (121d) can provide a space for the lower part of the agitator (250) to be received.

[0250] An air return port (125b) may be formed in the agitator receiving portion (121d). The air return port (125b) may be formed on the side of the agitator receiving portion (121d). The air return port (125b) may connect the recess (121da) and the dust collection motor (145) through a return flow path. The recess (121da) and the return flow path may be connected through the air return port (125b). Thus, air discharged from the dust collection motor (145) may pass through the air return port (125b) and be discharged to the recess (121da) of the agitator receiving portion (121d).

[0251] The agitator receiving portion (121d) can guide air discharged through the air circulation port (125b) to the suction portion (211) of the robot vacuum cleaner (200).

[0252] Meanwhile, the base (121) may be provided to be withdrawable from the housing (110) and the drawer (190). At this time, the base (121) may be withdrawn through the entrance (127) along the space between the inner walls (124).

[0253] To facilitate this, a base handle (121e) may be formed on the base (121). The base handle (121e) may be formed between the agitator receiving portion (121d) and the auxiliary wheel guide portion (121bb). Additionally, the base handle (121e) may be formed between a pair of wheel guide portions (121ba).

[0254] The base handle (121e) may be formed in a recessed shape on the base body (121a), and may be formed in a recessed shape extending from the rear to the front and downward. For example, the base handle (121e) may be formed in an elliptical groove shape, with a cover formed at the front and an open shape at the rear.

[0255] With this configuration, the user can easily pull out the base (121) by grasping and pulling the handle (121e).

[0256] The connecting wall (123) is configured to accommodate the dust passage hole (123a), power supply terminal (123b), and water supply nozzle (123c) of the robot vacuum cleaner station (100). The connecting wall (123) can spatially separate the receiving space (S) from the parts of the robot vacuum cleaner station (100). The connecting wall (123) can extend along the vertical direction from the rear side of the base (121). The connecting wall (123) can be formed in correspondence with the shape of the robot vacuum cleaner (200). For example, if the body (210) of the robot vacuum cleaner (200) is cylindrical, the connecting wall (123) can be formed in an arc shape having a predetermined radius. With such a configuration, the outer perimeter of the robot vacuum cleaner (200) can be surrounded, and the surface area facing the outer surface of the robot vacuum cleaner (200) can be increased. Additionally, the robot vacuum cleaner (200) can be stably supported.

[0257] A dust passage hole (123a) may be formed in the seating portion (120) to allow air from outside the housing (110) to flow into the interior. Specifically, a dust passage hole (123a) may be formed in the coupling wall (123) to allow air from outside the housing (110) to flow into the interior. At this time, the dust passage hole (123a) may be positioned at the rear of the dust collection housing (141) to be described later.

[0258] The dust passage hole (123a) may be connected to the dust bin (220) of the robot vacuum cleaner (200). The dust passage hole (123a) may be connected to the dust outlet (221) of the dust bin (220) of the robot vacuum cleaner (200). The dust passage hole (123a) may be formed in the shape of a hole corresponding to the shape of the dust bin (220) so that dust from the dust bin (220) flows into the dust collection unit (140).

[0259] The dust passage hole (123a) can be formed to communicate with the dust collection passage (147, 148). Air sucked into the dust passage hole (123a) can be exhausted through the air return section (125) after flowing through the dust collection passage (147, 148).

[0260] The robot vacuum cleaner station (100) may include a power supply module that supplies power to the robot vacuum cleaner (200). The power supply module includes a power supply module housing and a power supply terminal (123b), and a circuit board and components for power supply may be mounted within the power supply module housing. The power supply terminal (123b) may be positioned forward from the power supply module housing and exposed on the coupling wall (123).

[0261] The power supply terminal (123b) can supply power to a robot vacuum cleaner (200) coupled to the mounting portion (120). The power supply terminal (123b) can be electrically connected by contacting the charging terminal of the robot vacuum cleaner (200). The power supply terminal (123b) can be placed on the mounting portion (120). Specifically, the power supply terminal (123b) can be placed on the coupling wall (123). The power supply terminal (123b) can be electrically connected to the robot vacuum cleaner (200) coupled to the coupling wall (123). The power supply terminal (123b) can supply power to the battery of the robot vacuum cleaner (200) coupled to the coupling wall (123).

[0262] The robot vacuum cleaner station (100) may further include a water supply nozzle (123c).

[0263] The water supply nozzle (123c) can be connected to the supply section (231) of the water tank (230) of the robot vacuum cleaner (200). Specifically, the water supply nozzle (123c) can be connected to the inlet of the water tank (230). The water supply nozzle (123c) can supply water supplied from the water supply pipe of the kitchen cabinet (2) to the storage space inside the water tank (230) of the robot vacuum cleaner (200).

[0264] The inner wall (124) is configured to spatially separate the receiving space (S) of the seating portion (120) from the parts of the robot vacuum cleaner station (100). A pair of inner walls (124) may be arranged on the left and right sides of the base (121). The inner walls (124) may be connected to both ends of the connecting wall (123). The inner walls (124) may extend from the left and right sides of the base (121) in a direction intersecting the base (121). Specifically, the inner walls (124) may extend vertically from the left and right sides of the base (121).

[0265] Meanwhile, various components such as dust collection channels (147, 148), dust collection unit (140), dust collection motor (145), detergent container (163), and wastewater container (166) may be arranged on the outer side of the inner wall (124). Specifically, the dust collection unit (140), detergent container (163), and wastewater container (166) may be arranged in the space between the inner wall (124) and the outer wall (111) of the housing (110).

[0266] The dust collector (140) and the detergent container (163) can be separated by sliding from the space between the inner wall (124) and the outer wall (111) of the housing (110). The left-right width of the dust collector (140) and the detergent container (163) can be formed to be smaller than the distance between the inner wall (124) and the outer wall (111) of the housing (110).

[0267] The cleaning plate (122) is configured to clean the mop of the robot vacuum cleaner (200), and the cleaning plate (122) can be placed in the cleaning tank (128) of the base (121). Additionally, the cleaning plate (122) can come into contact with the mop (242) while the robot vacuum cleaner (200) is placed thereon.

[0268] The cleaning plate (122) may be a plate formed to slope downward as it faces the center overall.

[0269] Specifically, the cleaning plate (122) includes a flow guide surface (122c) formed in a curved shape. In addition, at least one passage hole (122b) through which fluid can pass may be formed in the flow guide surface (122c). Furthermore, a cleaning projection (122a) may be formed protrudingly on the flow guide surface (122c).

[0270] At this time, a pair of cleaning protrusions (122a) may be symmetrically formed on the fluid guide surface (122c). Specifically, a pair of cleaning protrusions (122a) may be positioned vertically below a pair of mops (242) of a robot vacuum cleaner (200), positioned to face the pair of mops (242), and positioned to be able to contact at least a part of the pair of mops (242).

[0271] Additionally, multiple through holes (122b) may be formed on the flow guide surface (122c), and may be formed between a pair of washing protrusions (122a). For example, multiple through holes (122b) may be formed on the flow guide surface (122c), including the lowest position from the ground (kitchen floor), and may be formed between a pair of washing protrusions (122a). Through this, fluid discharged between a pair of washing protrusions (122a) can be guided into the through holes (122b) and flow.

[0272] Meanwhile, the height of the flow guide surface (122c) from the kitchen floor can increase as it moves further back from the location where the through hole (122b) is formed. That is, the height of the flow guide surface (122c) from the kitchen floor can increase as it approaches the external air discharge section (171c) to be described later.

[0273] With this configuration, washing water and / or air can flow along the flow guide surface (122c) and escape through the through hole (122b) into the space formed between the washing plate (122) and the washing tank (128).

[0274] When washing water is supplied to the washing plate (122) and the mop (242) is rotated, the mop (242) can be washed by friction with the stationary washing protrusion (122a).

[0275] Meanwhile, at least a portion of the cleaning plate (122) may be positioned above the flow path forming portion (128c) to be described later. That is, the cleaning plate (122) may further include a reflux flow path cover portion (122d) that is formed to protrude upward from the flow guide surface (122c) and is coupled to the upper side of the flow path forming portion (128c).

[0276] The cleaning plate (122) of the present embodiment may be formed in a shape corresponding to the shape of the flow path forming portion (128c). For example, the front left portion of the cleaning plate (122) may be formed to protrude upward from the flow guide surface (122c) to cover the lower flow path forming portion (128c).

[0277] With this configuration, the washing plate (122) and the washing tank (128) can be accurately combined, while also providing sufficient space to form a reflux channel (125a).

[0278] The washing tank (128) is configured to accommodate the washing plate (122). The washing tank (128) may be positioned at the rear side of the base body (121a). The washing tank (128) is positioned at the lower side of the washing plate (122) and is detachably coupled to the washing plate (122). The washing tank (128) may be formed to correspond to the washing plate (122) so that the washing plate (122) can be fitted into it. Liquid that has passed through the washing plate (122) may flow into the washing tank (128).

[0279] The washing tank (128) may include a washing tank base surface (128a) through which fluid passing through the washing plate (122) flows, and a washing tank wall (128b) that is formed to protrude vertically from the outer edge of the washing tank base surface (128a). At this time, the height of the washing tank base surface (128a) from the ground (kitchen floor) may decrease as it moves toward the rear of the robot vacuum cleaner station (100). Through this, fluid passing through the washing plate (122) can be collected at the rear of the washing tank (128) and discharged to the outside through the wastewater inlet (166a) to be described later.

[0280] At this time, a sewage pipe connection port (128d) may be formed in the wall of the washing tank (128b) for connection with the sewage inlet port (166a).

[0281] Meanwhile, a flow path forming portion (128c) may be formed in the washing tank (128). The flow path forming portion (128c) may be formed protruding upward from the base surface (128a) of the washing tank to form a reflux flow path (125a) on the lower side. Specifically, at least a portion of the reflux flow path (125a) may be formed between the lower surface of the base (121) and the flow path forming portion (128c).

[0282] Meanwhile, in the present invention, the washing tank (128) is provided to be withdrawable from the mop washing unit (160). That is, the washing tank (128) can be withdrawn from the housing (110) together with the base (121). Along with this, the washing plate (122) can also be withdrawn from the mop washing unit (160).

[0283]

[0284] Door section

[0285]

[0286] The door portion (130) may be provided to cover the entire front end of the housing (110). The door (131) may cover the dust bag drawer (144) and the detergent container (163) so that they are not exposed to the outside.

[0287] The door (131) can form the front exterior of the robot vacuum cleaner station (100) when the entrance (127) is closed. For example, the door (131) can be formed in a shape similar to a rectangular flat plate. The left-right length of the door (131) can be provided to be greater than or equal to the left-right length of the housing (110). With this configuration, the dust bag drawer (144) and the detergent container (163) can be protected from the outside, and the appearance of the robot vacuum cleaner station (100) can be made neat.

[0288] A door frame (132) may be positioned at the front of the housing (110). A door (131) is connected to the door frame (132) so that it can be opened and closed. Additionally, the door frame (132) may be formed with an entrance (127) through which a robot vacuum cleaner (200) can enter and exit, a dust bag outlet (132a) to which a dust bag drawer (144) can be pulled out, and a detergent container insertion opening (132b) to which a detergent container (163) can be pulled out.

[0289] The door frame (132) can form the front exterior of the robot vacuum cleaner station (100) when the door (131) is open.

[0290] When the door (131) opens the entrance (127), at least one side of the dust bag drawer (144) and at least one side of the detergent container (163), which are connected to the door frame (132), may be provided to be exposed to the outside. When the door (131) opens the entrance (127), the front side of the dust bag drawer (144) and the front side of the detergent container (163) are exposed to the outside, and the handle (144d) of the dust bag drawer (144) and the handle (163b) of the detergent container (163) are exposed to the outside. With this configuration, the dust bag drawer (144) and the detergent container (163) can be easily pulled out or inserted and can provide a neat appearance.

[0291] The door (131) has a rotation axis (131a) positioned at the bottom of the door frame (132) and can be positioned parallel to the floor surface when opening the doorway (127) or formed to slope downward toward the front so that the end contacts the ground.

[0292] The door (131) is provided with a hinge portion so that it can be rotatably connected to the door frame (132). Multiple hinge portions may be spaced apart along the rotation axis (131a) and spaced apart at different intervals.

[0293] Additionally, the door (131) may be provided with an auxiliary entryway (131b) on the side facing the housing (110) when the entrance (127) is closed. The auxiliary entryway (131b) is provided so that the robot vacuum cleaner (200) can travel stably to the landing area (120) or the entrance (127), and may be provided with an upward slope toward the rear.

[0294] Specifically, the auxiliary entryway (131b) can be formed in the shape of a groove to ensure stable inclined driving of the robot vacuum cleaner (200). The auxiliary entryway (131b) may have grooves formed along the left and right directions spaced apart at equal intervals in the front and rear directions. The width of the auxiliary entryway (131b) in the left and right directions may become narrower as it moves toward the rear. Accordingly, as the wheels (260) of the robot vacuum cleaner (200) move toward the seating portion (120) or the entrance (127), left and right movement is restricted, and the wheels can be guided to the correct position.

[0295] The auxiliary entryway (131b) guides the wheel (260) to the wheel guide section (121ba) positioned on the seating section (120). The auxiliary entryway (131b) is provided in a pair and can be positioned at each location continuous with the pair of wheel guide sections (121ba).

[0296] Meanwhile, the door (131) may be driven according to whether the robot vacuum cleaner (200) approaches, whether it starts driving, etc., or according to the input of the door control unit (133).

[0297] The door frame (132) is equipped with an entry sensor (135) to detect the approach of the robot vacuum cleaner (200). The entry sensor (135) may be positioned at the front of the housing (110) to detect the approach of the robot vacuum cleaner (200). For example, the entry sensor (135) may be an IR sensor.

[0298] The entry sensor (135) can be installed on the upper side of the front surface of the door frame (132). This allows the detection range to be maximized. Additionally, the entry sensor (135) can be installed in the center of the left and right directions of the entrance (127). This allows the entry direction of the robot vacuum cleaner (200) to be guided through communication with the robot vacuum cleaner (200).

[0299] Meanwhile, in order for the entry sensor (135) to detect the front even when the door (131) is closed to the entrance (127), the door (131) may be formed in a shape with a cut-out position facing the entry sensor (135). Alternatively, the door (131) may be provided with a transparent window at a position facing the entry sensor (135).

[0300] A door operating part (133) is installed on the door frame (132) so that the door (131) can be rotated by the user's operation.

[0301] The door control unit (133) is positioned on the door frame (132) and may be provided with at least one button for operating the door (131). The door control unit (133) can rotate the door (131) regardless of the position or state of the robot vacuum cleaner (200). The door control unit (133) may be provided with a single button for opening or closing the door (131), or may be provided with a button for opening the door (131) and a button for closing the door (131), respectively.

[0302] The door control unit (133) may be positioned inside the door frame (132). Additionally, the door control unit (133) may be positioned so that at least one button is exposed to the outside.

[0303] At this time, the button may be positioned adjacent to the detergent container (163) relative to the entrance. For example, the button may be positioned above the handle (163b) of the detergent container (163).

[0304] Meanwhile, when the door (131) closes the entrance (127), it also covers the door control unit (133). At this time, the door (131) is provided with an external button unit (131c) so that the door control unit (133) can be operated even when the entrance (127) is closed. The external button unit (131c) is composed of the same number of buttons as the door control unit (133) and is provided in a position facing the buttons. The external button unit (131c) is formed of an elastically deformable material so that it can press the buttons when an external force is applied.

[0305] The door (131) can be rotated by a door drive unit (134). For example, the door drive unit (134) may include a door drive motor and a drive gear unit.

[0306] The door drive motor can be placed inside the housing (110) and in the upper space of the detergent container (163). The door drive motor can be placed between the detergent container (163) and the upper cover (113) of the housing (110). Additionally, the door drive motor can be placed forward in the space provided between the outer wall (111) and the seating portion (120). That is, the door drive motor can be placed adjacent to the door operating portion (133).

[0307] Through this, space utilization is improved and accessibility is enhanced, providing convenience to users.

[0308] The drive gear unit is configured to transmit power by connecting the door drive motor and the door (131). The drive gear unit transmits the driving force of the door drive motor to the door (131) to rotate the door (131).

[0309]

[0310] Dust collector

[0311]

[0312] FIGS. 12 to 25 illustrate drawings for explaining the dust collection unit of a robot vacuum cleaner station according to an embodiment of the present invention.

[0313] Referring to FIGS. 12 to 25, the dust collection unit (140) is described as follows.

[0314] The dust collection unit (140) can collect dust from the dust bin (220) of the robot vacuum cleaner (200). The dust collection unit (140) can be placed inside the housing (110). The dust collection unit (140) can be placed outside the seating unit (120). That is, the dust collection unit (140) can be placed between the housing (110) and the seating unit (120). For example, the dust collection unit (140) can be placed on one side in the left-right direction of the seating unit (120).

[0315] The dust collection unit (140) may include a dust collection unit housing (141), a filter (142), a dust bag (143), a dust bag drawer (144), a dust collection motor (145), a dust collection motor housing (146), a first dust collection path (147), and a second dust collection path (148).

[0316] The dust collection housing (141) can form a space inside which a filter (142), a dust bag (143), and a dust bag drawer (144) can be accommodated.

[0317] The dust collection housing (141) is coupled to the inside so that a dust bag drawer (144) can be pulled out, and a dust bag (143) can be stored inside the dust bag drawer (144). For example, the dust collection housing (141) is formed in the shape of a rectangular tube with an open front, and the rear internal space can be connected to the first dust collection path (147) and the second dust collection path (148).

[0318] The dust collection housing (141) can receive dust from inside the dust bin (220).

[0319] One side of the interior of the dust collection housing (141) may be in communication with the first dust collection path (147), and the other side may be in communication with the second dust collection path (148). Additionally, when a dust bag (143) is attached to the dust collection housing (141), the dust bag (143) may be in communication with the first dust collection path (147) inside the dust collection housing (141).

[0320] Specifically, the dust collection housing (141) may have an inlet (141a) communicating with the first dust collection path (147) and an outlet (141b) communicating with the second dust collection path (148).

[0321] At this time, the inlet (141a) may be positioned above the outlet (141b). Through this, air and dust introduced through the inlet (141a) flow downward, and after dust is collected in the dust bag (143), it can be discharged through the outlet (141b). In this process, since the air flows from the upper side to the lower side, it has the effect of preventing the air from flowing upward or the dust from scattering upward.

[0322] Meanwhile, in this embodiment, the discharge port (141b) may be positioned further forward than the inlet port (141a). For example, the inlet port (141a) may be formed on the rear side of the dust collection housing (141), and the discharge port (141b) may be formed on the lower side of the dust collection housing (141). In this case, the discharge port (141b) may be positioned further forward than the rear side of the dust collection housing (141).

[0323] Meanwhile, the discharge port (141b) may be formed by combining the dust collection housing (141) and the dust bag drawer (144). In this case, the discharge port (141b) of the dust collection housing (141) and the discharge port (144c) of the dust bag drawer (144) may refer to the same space.

[0324] Meanwhile, the dust collection housing (141) may be equipped with a dust bag detection unit (141c). The dust bag detection unit (141c) may be positioned on the rear side of the dust collection housing (141). The dust bag detection unit (141c) may be positioned on the rear side of the dust collection housing (141) in the direction of the dust bag drawer (144).

[0325] The dust bag detection unit (141c) can detect the dust bag (143). For example, the dust bag detection unit (141c) may be a micro switch. The dust bag detection unit (141c) can detect the presence of the dust bag (143) by contacting the dust bag (143). Specifically, the dust bag detection unit (141c) can detect the presence of the dust bag (143) by contacting the attachment / detachment (143b) of the dust bag (143).

[0326] According to the present invention, a dust bag detection unit (141c) is provided in the dust collection unit housing so that when the dust bag (143) is coupled, it is possible to detect that the dust bag (143) is mounted.

[0327]

[0328] Meanwhile, a sterilization module (150) may be coupled to the dust collection housing (141). For example, the dust collection housing (141) may have a hot air inlet through which hot air is introduced from the sterilization module (150) and a hot air exhaust port through which hot air is exhausted. At this time, the hot air inlet and the hot air exhaust port may be formed on the rear side of the dust collection housing (141) and may be positioned on both the left and right sides of the rear side of the dust collection housing (141). Additionally, the hot air inlet may be positioned closer to the ground than the hot air exhaust port. That is, the hot air inlet and the hot air exhaust port may be positioned diagonally opposite each other on the rear side of the dust collection housing (141), which is in the shape of a rectangular surface. Through this, the flow path of the hot air can be made as far as possible.

[0329] As another example, a sterilization module (150) that irradiates light into the interior of the dust collection housing (141) may be attached to the upper surface of the dust collection housing (141). In this case, the light may be ultraviolet (UV-C).

[0330] The dust bag drawer (144) includes a dust bag drawer body (144a), an inlet (144b), an outlet (144c), a handle (144d), and a flow path forming part (144e).

[0331] The dust bag drawer body (144a) may provide a space for attaching a dust bag (143) inside. For example, the dust bag drawer body (144a) may be formed in the shape of a box with an open top, and an inlet (144b) may be formed on the rear side to communicate with the first dust collection channel (147). At this time, the inlet (144b) may communicate with the inlet (141a) of the dust collection housing (141).

[0332] The upper side of the dust bag drawer body (144a) may be connected to the first dust collection channel (147) through the inlet (144b). The inlet (144b) may be configured to guide air flowing through the first dust collection channel (147) into the interior of the dust bag (143). The inlet (144b) may be connected to the first dust collection channel (147) and the dust bag (143). Accordingly, dust sucked in from the dust bin (220) of the robot vacuum cleaner (200) can move into the interior of the dust bag (143) through the first dust collection channel (147), the inlet (141a) of the dust collection housing (141), and the inlet (144b) of the dust bag drawer (144).

[0333] The dust bag drawer (144) may be connected to the second dust collection channel (148) through an outlet (144c) formed on the lower surface (bottom surface). The outlet (144c) may be configured to guide air passing through the dust bag (143) to the second dust collection channel (148). That is, the outlet (144c) may be formed to be connected to the internal space formed by combining the channel forming part (144e) and the bottom surface of the dust collection housing (141).

[0334] At this time, the discharge port (144c) may be positioned at a different height from the inlet port (144b). The discharge port (144c) may be positioned lower than the inlet port (144b) relative to the lower surface (bottom surface) of the dust bag drawer (144). The discharge port (144c) may connect the internal space of the dust bag drawer (144) with the second dust collection path (148). Thus, air that has been filtered of dust while passing through the dust bag (143) can move to the second dust collection path (148) via the discharge port (144c).

[0335] Meanwhile, in this embodiment, the outlet (144c) may be positioned further forward than the inlet (144b). For example, the outlet (144c) may be positioned closer to the handle (144d) than the inlet (144b).

[0336] Meanwhile, the dust bag drawer (144) forms a passageway for discharging air that has passed through the dust bag (143) to the dust collection motor (145). That is, the dust bag drawer (144) includes a passageway forming part (144e) that is formed protruding upward from the bottom surface of the dust bag drawer body (144a) and forms a passageway between it and the dust collection housing (141).

[0337] The flow path forming part (144e) is provided on the lower side of the dust bag drawer body (144a) and can form at least a part of the second dust collection flow path (148). The flow path forming part (144e) can be formed such that a pair of side walls facing each other on the lower side (bottom surface) of the dust bag drawer body (144a) are bent upward and extended, and are covered by an upper side wall connecting the pair of side walls.

[0338] Accordingly, at least a portion of the second dust collection channel (148) can be formed by combining the channel forming portion (144e) and the bottom surface of the dust collection housing (141).

[0339] Meanwhile, the flow path forming portion (144e) may be formed along the longitudinal direction of the dust bag drawer (144). At this time, an outlet (144c) may be formed at one end of the longitudinal direction of the flow path forming portion (144e).

[0340] Accordingly, air introduced into the outlet (144c) can flow to the rear along the length direction of the flow path forming section and be discharged to the dust collection motor (145).

[0341] Meanwhile, the remainder of the second dust collection path (148) may be a space formed by combining the dust collection motor support (146c) and the dust collection motor lower housing (146b), which will be described later.

[0342] Accordingly, in this embodiment, the first dust collection channel (147) and the second dust collection channel (148) may be formed at different heights. That is, the first dust collection channel (147) and the second dust collection channel (148) may be arranged in a stacked structure. At this time, at least a portion of the first dust collection channel (147) may be positioned above the second dust collection channel (148).

[0343] In addition, the first dust collection channel (147) and the second dust collection channel (148) may be formed on different sides of the dust collection housing (141). For example, the first dust collection channel (147) may be formed on the rear side of the dust collection housing (141), and the second dust collection channel (148) may be formed along the lower side of the dust collection housing (141).

[0344] Through this, air introduced from the rear upper side of the dust bag drawer (144) flows to the front lower side of the dust bag drawer (144) as it passes through the dust bag (143), so that the air containing dust can be evenly spread inside the dust bag (143) and prevent dust from accumulating intensively at a specific location in the dust bag (143).

[0345] Meanwhile, a handle (144d) may be provided on the front of the dust bag drawer body (144a). The handle (144d) may be provided so that a user can grip it. For example, the handle (144d) may be in the form of a groove formed by being recessed from the front surface of the dust bag drawer body (144a) toward the rear.

[0346] Accordingly, according to the present invention, a user can easily pull the dust bag drawer (144) forward (first direction) and then lift the dust bag (143) upward (second direction) to remove and replace it.

[0347] Meanwhile, in this embodiment, a gasket may be further provided in the dust bag drawer (144). The gasket may be placed around the front perimeter of the dust bag drawer (144). The gasket can seal the gap formed between the dust collection housing (141) and the dust bag drawer (144) when the dust bag drawer (144) is inserted into the dust collection housing (141).

[0348] Meanwhile, a sensor pass-through hole (144g) may be formed in the dust bag drawer (144). The sensor pass-through hole (144g) may be formed so that at least a portion of the dust bag detection portion (141c) of the dust collection housing (141) can pass through it. For example, the sensor pass-through hole (144g) may be formed in the shape of a square hole at a position facing the dust bag detection portion (141c). Thus, at least a portion of the dust bag detection portion (141c) may pass through the sensor pass-through hole (144g) and be positioned, and may come into contact with the dust bag (143) when the dust bag (143) is combined with the dust bag drawer (144).

[0349] A filter (142) may be provided in a dust bag drawer (144). The filter (142) may be placed in the outlet (144c) of the dust bag drawer (144). That is, the filter (142) may be placed on the lower surface of the dust bag drawer (144). Thus, when the dust bag drawer (144) is pulled out, the filter (142) may be pulled out together with the dust bag drawer (144). Meanwhile, the filter (142) may be placed below the dust bag (143).

[0350] The filter (142) can filter foreign substances from the air discharged after flowing through the internal space of the dust bag (143) and the dust bag drawer (144). By doing so, the filter (142) can prevent foreign substances from entering the dust collection motor (145) and damaging the dust collection motor (145). For example, the filter (142) may be a pre-filter.

[0351]

[0352] The dust bag (143) may refer to a dust bag that collects dust sucked in from inside the dust bin (220) of the robot vacuum cleaner (200) by the dust collection motor (145).

[0353] The dust bag (143) can be detachably connected to the dust bag drawer (144).

[0354] At this time, the dust bag drawer (144) is coupled to the dust collection housing (141) so as to be drawn out along a first direction, and the dust bag (143) can be detachably coupled to the dust bag drawer (144) along a second direction intersecting the first direction. For example, the dust bag drawer (144) can be coupled to the dust collection housing (141) so as to be drawn out forward and backward, and the dust bag (143) can be detachably coupled to the dust bag drawer (144) along an up-and-down direction.

[0355] The dust bag (143) can be separated from the dust bag drawer (144) and discarded, and a new dust bag (143) can be attached to the dust bag drawer (144). That is, the dust bag (143) can be defined as a consumable part.

[0356] The dust bag (143) includes a dust bag body (143a), a detachable part (143b), a light-emitting part (143c), and an air inlet part (143d).

[0357] The dust bag body (143a) can collect dust. The dust bag body (143a) can be configured to expand in volume and accommodate dust inside when suction force is generated by the dust collection motor (145). To this end, the dust bag body (143a) can be made of a material that allows air to pass through but does not allow foreign substances such as dust to pass through. For example, the dust bag body (143a) can be made of a non-woven fabric material and can have a cuboid shape corresponding to the shape of the dust bag drawer (144) when the volume is expanded.

[0358] The detachable part (143b) is coupled to the dust bag body (143a) and can be detachably coupled to the rear side of the dust bag drawer (144) in a sliding manner. For example, the detachable part (143b) may be formed in a flat plate shape and coupled to the rear side of the dust bag body (143a), and can be detachably coupled in a sliding manner to a dust bag coupling part disposed on the rear side of the dust bag drawer (144). Meanwhile, a guide rail (144h) that guides the coupling of the detachable part (143b) may be formed on the dust bag drawer (144). The guide rail (144h) may be formed along the rear side of the dust bag drawer (144).

[0359] At this time, the detachable part (143b) may be formed in the shape of a square plate overall. At this time, the vertical height and horizontal width of the detachable part (143b) may be formed to be equal to or larger than the vertical height and horizontal width of the rear side of the dust bag body (143a). Through this, the user can easily attach the detachable part (143b) to the dust bag drawer (144) by gripping it.

[0360] Meanwhile, according to an embodiment, the detachable part (143b) in the shape of a square plate may have two corner portions on opposite sides cut out. For example, the cut portion (143ba) may be formed by cutting two corner portions on opposite sides of the detachable part (143b) into a rectangular shape. This may be a location that communicates with the flow path for the inflow and outflow paths for the hot air for sterilization. Through this, the dust bag (143) can be sterilized by hot air.

[0361] With this configuration, the dust bag (143) can be connected along the vertical direction. Therefore, in a dust bag (143) where the horizontal length is longer than the vertical height, the volume of the structure required for mounting the dust bag (143) can be reduced. As a result, the capacity to collect dust within a limited space can be increased.

[0362] Meanwhile, a stopper (143bb) may be formed on the attachment / detachment (143b). The stopper (143bb) may be formed to protrude toward the dust bag drawer (144) from the upper part of the outer surface (the surface facing the dust bag drawer (144)) of the attachment / detachment (143b). At this time, the stopper (143b) may be formed to protrude in a rib shape along the left / right direction (width direction). With this configuration, when the dust bag (143) is attached to the dust bag drawer (144), the stopper (143b) may be caught on the upper part of the rear surface of the dust bag drawer (144). Therefore, even if the dust bag (143) is attached to the dust bag drawer (144), the upper part of the detachable part (143b) may be exposed to the upper side, and the user may be provided with the convenience of being able to detach the dust bag (143) by holding the stopper (144b) and lifting it upward.

[0363] Meanwhile, an inlet (143bc) through which dust from the dust bin (220) flows may be formed in the detachable part (143b). The inlet (143bc) may be arranged to communicate with the inlet (144b) of the dust bag drawer (144). Thus, when the dust collection motor (145) is operated, air and dust inside the dust bin (220) may flow into the dust bag body (143a) and be collected. The inlet (143bc) may communicate with the inlet pipe (143db) to be described later.

[0364] The light-emitting part (143c) is coupled to the dust bag body (143a) and can transmit light into the interior of the dust bag body (143a). At this time, the light-emitting part (143c) and the detachable part (143b) may be positioned on different sides of the dust bag body (143a). For example, the light-emitting part (143c) may be formed in the shape of a flat plate and coupled to the upper side of the dust bag body (143a), and can transmit light irradiated from a sterilization module positioned on the upper side of the interior of the dust collection housing.

[0365] At this time, the light-emitting part (143c) can be formed in the shape of a square plate overall. At this time, the light-emitting part (143c) can be formed integrally with the detachable part (143b). Specifically, the light-emitting part (143c) can be formed in a shape that is bent and extended from the detachable part (143b). Through this, when the detachable part (143b) is attached to the dust bag drawer (144), the light-emitting part (143c) is also stably supported.

[0366] Meanwhile, the light-emitting part (143c) may be optionally configured with the cut part (143ba), but it is also possible to have both. Through this, the hygiene of the dust bag (143) can be improved.

[0367] A light-transmitting window (143ca) is provided in the light-transmitting portion (143c). The light-transmitting window (143ca) is formed of a material capable of transmitting light. Specifically, the light-transmitting window (143ca) may be formed of a material capable of transmitting light including ultraviolet light. For example, the light-transmitting window (143ca) may be formed of a material capable of transmitting UV-C.

[0368] The light-transmitting window (143ca) can be positioned facing the light source of the sterilization module (150) provided in the dust collection housing (141). Accordingly, light irradiated from the light source can pass through the light-transmitting window (143ca) to sterilize the interior of the dust bag body (143a).

[0369] With this configuration, insects and microorganisms, including powder mites present inside the dust bag (143), can be sterilized to improve hygiene.

[0370] Meanwhile, an inlet (143bc) into which dust from the dust bin (220) is introduced may be formed in the detachable part (143b). The inlet (143bc) may be arranged to communicate with the inlet (144b) of the dust bag drawer (144). Thus, when the dust collection motor (145) is operated, air and dust inside the dust bin (220) may be introduced into the dust bag body (143a) and collected.

[0371] Meanwhile, the dust bag (143) may further include an air inlet (143d) inside the envelope-shaped dust bag body (143a). The air inlet (143d) may be positioned facing the detachable part (143b) with the dust bag body (143a) in between. The air inlet (143d) may be coupled with the detachable part (143b) with the dust bag body (143a) in between. That is, if the detachable part (143b) is provided on the rear outer surface of the dust bag body (143a), the air inlet (143d) may be provided on the rear inner surface of the dust bag body (143a). Through this, the shape of the rear portion of the dust bag body (143a) in the form of an envelope can be supported, and the connection part between the dust bag body (143a) and the detachable part (143b) can be broken, thereby preventing the envelope portion of the dust bag body (143a) from bursting and dust from scattering.

[0372] The air inlet (143d) may include an inlet plate (143da), an inlet pipe (143db), an inlet cover (143dc), and a guide wall (143dd).

[0373] The inlet plate (143da) is formed in a flat plate shape, and one side is positioned to face the detachable part (143b) and is coupled with the detachable part (143b) and / or the dust bag body (143a), and the other side may have an inlet pipe (143db) and a guide wall (143dd) protrudingly formed.

[0374] For example, the inlet plate (143da) may be formed in the shape of a square flat plate, but the four corner portions may be formed in a curved shape. With this configuration, damage to the dust bag body (143a) caused by the corner portions can be prevented.

[0375] The inlet pipe (143db) can be formed to protrude in a cylindrical shape from the inlet plate (143da). At this time, the inlet pipe (143db) can be formed along the drawing direction of the dust bag drawer (144). Through this, air can be smoothly drawn in from the dust container (220) positioned behind the dust bag (143).

[0376] Meanwhile, the protruding height of the inlet pipe (143db) may not be uniform. For example, the protruding height of the inlet pipe (143db) may increase as it moves from the vertical lower side to the upper side. Through this, the inlet cover (143dc) can close the inlet pipe (143db) with uniform surface pressure.

[0377] An inlet is formed in the inlet pipe (143db) and can be connected to an inlet (143bc) formed in the detachable part (143b). Accordingly, the inlet pipe (143db) can guide dust inside the dust container (220) into the dust bag body (143a).

[0378] The inlet cover (143dc) can open and close the inlet. The inlet cover (143dc) can be formed in a shape having a larger diameter than the inlet pipe (143db).

[0379] The inlet cover (143dc) includes a fixed part (143dca) that is fixedly coupled to the inlet plate (143da) and an opening / closing part (143dcb) that opens and closes the inlet pipe by the suction force of the dust collection motor (145). At this time, when the dust bag (143) is coupled to the dust bag drawer (144), the fixed part (143dca) may be positioned lower than the opening / closing part (143dcb).

[0380] With this configuration, when the dust collection motor (145) is operated, the upper part of the inlet pipe (143db) opens first, allowing air to flow into the upper part of the internal space of the dust bag (143). Therefore, dust entering the dust bag (143) can be prevented from accumulating intensively just below the inlet.

[0381] Additionally, the inlet cover (143dc) may be formed of an elastic material. For example, the inlet cover (143dc) may be formed of a resin or rubber material. Accordingly, when the dust collection motor (145) is operated, the opening / closing part (143dcb) can be rotated by the suction force of the dust collection motor (145) to open and close the inlet.

[0382] The guide wall (143dd) can guide the flow direction of air passing through the inlet pipe (143db). The guide wall (143dd) can be formed as a pair protruding from the inlet plate (143da). The pair of guide walls (143dd) can be formed along the up and down direction from the inlet plate (143da).

[0383] At this time, an inlet pipe (143db) and an inlet cover (143dc) may be disposed between a pair of guide walls (143dd). At this time, the protrusion height of the pair of guide walls (143dd) may be greater than the protrusion height of the inlet pipe (143db).

[0384] With this configuration, a pair of guide walls (143dd) can block the air flowing between the inlet pipe (143db) and the inlet cover (143dc) from spreading in the left and right directions and guide it to flow toward the front of the vacuum cleaner station (100).

[0385] Therefore, through a pair of guide walls (143dd), the air flowing into the dust bag (143) can be spread evenly throughout the dust bag (143).

[0386]

[0387] The dust collection unit (140) may further include a dust collection module. The dust collection module may provide an intake airflow to the dust collection path.

[0388] Specifically, the dust collection unit (140) may further include a dust collection motor (145) and a dust collection motor housing (146).

[0389] The dust collection motor (145) can generate suction force in the dust collection path (147, 148). That is, the dust collection motor (145) can provide suction force to suck dust from the dust container (220) into the dust bag (143) placed in the dust collection housing (141).

[0390] The dust collection motor (145) can be positioned at the rear of the dust collection housing (141). By doing so, the dust collection motor (145) can provide suction power to suck up dust inside the dust bin (220) of the robot vacuum cleaner (200).

[0391] The dust collection motor (145) can generate suction force by rotation. For example, although not illustrated, the dust collection motor (145) may include a rotor and a stator that rotate relative to each other when power is applied, and may include an impeller that rotates around a rotation axis according to the rotation of the rotor. Thus, suction force can be generated by the rotation of the impeller.

[0392] One side of the dust collection motor (145) may be connected to the second dust collection path (148), and the other side may be connected to the recirculation path (125a). When the dust collection motor (145) is driven, air flowing through the second dust collection path (148) may be introduced into the interior of the dust collection motor housing (146). Additionally, the air introduced into the interior of the dust collection motor housing (146) may flow through the recirculation path (125a) after passing through the dust collection motor (145).

[0393] Meanwhile, in this embodiment, the rotation axis of the dust collection motor (145) may be arranged along the vertical direction. In this case, the horizontal space occupied by the dust collection motor (145) can be minimized.

[0394] Meanwhile, if the rotation axis of the dust collection motor (145) is arranged along the vertical direction, the height of the side where air flows into the dust collection motor (145) and the side where air is discharged from the dust collection motor (145) can be arranged differently. Accordingly, the structure of the dust collection motor housing (146) can be formed.

[0395] The dust collection motor housing (146) can accommodate a dust collection motor (145) inside. The dust collection motor housing (146) can be positioned at the rear of the dust collection unit housing (141). Additionally, the dust collection motor housing (146) can be positioned at the rear of the first dust collection path (147). Additionally, the dust collection motor housing (146) can be positioned at the rear of the second dust collection path (148).

[0396] That is, based on the front-rear direction of the robot vacuum cleaner station (100), the dust collection housing (141) may be positioned furthest forward, and the first dust collection path (147) and the second dust collection path (148) may be positioned behind the dust collection housing (141). Additionally, the dust passage hole (123a) may be positioned behind the first dust collection path (147), and the dust collection motor housing (146) may be positioned behind the second dust collection path (148). Additionally, the dust collection motor housing (146) may be positioned behind the dust passage hole (123a).

[0397] Accordingly, the dust collection unit (140) is positioned along the front and rear directions of the robot vacuum cleaner station (100) to have the effect of lowering the overall height.

[0398] In this embodiment, the dust collection motor housing (146) includes a dust collection motor upper housing (146a), a dust collection motor lower housing (146b), a dust collection motor support (146c), and a motor damper (146d).

[0399] At this time, the dust collector motor (145) is seated on the dust collector motor support (146c), the dust collector motor upper housing (146a) is coupled to the upper side of the dust collector motor support (146c), and the dust collector motor lower housing (146b) may be positioned on the lower side of the dust collector motor (145). Meanwhile, a motor damper (146d) may be coupled between the dust collector motor support (146c) and the dust collector motor upper housing (146b).

[0400] With this arrangement, the dust collector motor (145) can be seated on the dust collector motor support (146c), and after attaching the motor damper (146d), the dust collector motor upper housing (146a) can be assembled, and the dust collector motor lower housing (146b) can be assembled on the lower side of the housing (1110).

[0401] Therefore, the parts of the dust collection motor housing (146) can be assembled to the upper and lower sides of the dust collection motor (145), thereby facilitating assembly and repair work.

[0402] The upper housing (146a) of the dust collection motor may cover the upper side of the dust collection motor (145). The upper housing (146a) of the dust collection motor may include a motor receiving portion that accommodates a portion of the upper side of the dust collection motor (145) and an upper flow path forming portion that is connected to the motor receiving portion and forms a flow path inside.

[0403] The motor receiving portion may be formed in a shape similar to a cylinder, but with the top closed. Air discharged from the dust collecting motor (145) may flow through the space between the motor receiving portion and the dust collecting motor (145) and may be discharged to the upper flow path forming portion.

[0404] The upper flow path forming portion may be formed to extend radially outward from the outer surface of the motor receiving portion. Through this, the flow direction of air discharged between the motor receiving portion and the dust collection motor (145) can be guided. Additionally, the upper surface of the upper flow path forming portion may have a groove formed to accommodate at least a portion of a pipe or hose forming the first dust collection flow path (147).

[0405] With this configuration, at least a portion of the first dust collection channel (147) can pass through the upper side of the upper channel forming part.

[0406] The upper flow path forming part may form at least a portion of the reflux flow path (125a) inside. Specifically, the space formed by combining the upper flow path forming part and the dust collection motor support part (146c) may form a portion of the reflux flow path (125a).

[0407] The dust collection motor lower housing (146b) can cover the lower side of the dust collection motor (145). The dust collection motor lower housing (146b) can be coupled to the lower side of the drawer (190). The dust collection motor lower housing (146b) may include a lower cover portion positioned on the lower side of the dust collection motor (145) and a lower flow path forming portion connected to the lower cover portion and forming a flow path for air flowing into the dust collection motor (145).

[0408] The lower cover portion is formed in the shape of a disc, but the center of the circle may be formed in a raised shape toward the dust collection motor (145). With this configuration, the upward flow of air entering the dust collection motor (145) can be guided.

[0409] The lower flow path forming portion may be formed to extend radially outward from the lower cover portion. Through this, the flow of air entering from the dust collection housing (141) to the dust collection motor (145) can be guided.

[0410] The lower flow path forming part may form at least a portion of the second dust collection flow path (148) inside. Specifically, the space formed by combining the lower flow path forming part and the dust collection motor support part (146c) may form a portion of the second dust collection flow path (148).

[0411] The dust collection motor support (146c) can support the dust collection motor (145).

[0412] The dust collection motor support (146c) can be connected to various parts forming the internal structure of the robot vacuum cleaner station (100). The dust collection motor support (146c) can be connected to the dust collection housing (141). The dust collection motor support (146c) can be connected to the inner wall (124) or the connecting wall (123) of the seating portion (120). Through this, the dust collection motor support (146c) can provide a supporting force capable of supporting the dust collection motor (145).

[0413] The dust collection motor support (146c) can be combined with the dust collection motor upper housing (146a) and the dust collection motor lower housing (146b) to form a recirculation path (125a) and a second dust collection path (148), respectively. Specifically, the second dust collection path (148) can be formed on the lower side of the dust collection motor support (146c), and the recirculation path (125a) can be formed on the upper side of the dust collection motor support (146c).

[0414] Through this, multiple Euros can be arranged to be stacked on top of each other, thereby maximizing space efficiency within a limited height.

[0415] As a result of this arrangement, air introduced from inside the dust bin (220) passes between the dust collection motor support (146c) and the dust collection motor lower housing (146b) and flows into the dust collection motor (145), and passes through the dust collection motor (145) and can be discharged between the dust collection motor support (146c) and the dust collection motor upper housing (146a).

[0416] Therefore, according to the present invention, the dust collection motor (145) can be arranged along the vertical direction, and two separate upper and lower passages can be formed through the dust collection motor support (146c). Thus, the passages required for dust collection can be stacked within a limited height and left-right space, and air can be introduced and discharged using the stacked passages, thereby maximizing space efficiency.

[0417] Meanwhile, the motor damper (146d) is coupled between the dust collection motor support (146c) and the dust collection motor (145) and can elastically support the dust collection motor (145).

[0418] The motor damper (146d) can be coupled between the dust collection motor support (146c) and the dust collection motor upper housing (146a). That is, the upper side of the motor damper (146d) can be coupled to the dust collection motor upper housing (146a), and the lower side of the motor damper (146d) can be coupled to the dust collection motor support (146c). With this configuration, when the dust collection motor support (146c) and the dust collection motor upper housing (146a) are coupled, the motor damper (146d) can be fixed between the dust collection motor support (146c) and the dust collection motor upper housing (146a) to secure support.

[0419] Meanwhile, the motor damper (146d) can be formed from an elastic material.

[0420] Therefore, according to the present invention, by arranging the dust collection motor (145) along the vertical direction, a damper (146d) is provided at the bottom thereof, thereby having the effect of reducing vibration and noise generated by the operation of the dust collection motor (145).

[0421] Accordingly, according to the present invention, the damper (146d) has the effect of preventing air leakage by sealing the recirculation path (125a) formed between the dust collection motor support (146c) and the dust collection motor upper housing (146a).

[0422] Meanwhile, the dust collection unit (140) may further include dust collection channels (147, 148). A dust collection channel may refer to a channel through which air sucked in through a dust passage hole (123a) flows through a dust bag to a dust collection motor (145).

[0423] Specifically, the dust collection path may include a first dust collection path (147) that connects the dust bin (220) and the internal space of the dust collection unit housing (141) when the robot vacuum cleaner (200) is connected to the robot vacuum cleaner station (100) and the dust passage hole (123a) and the dust bin (220) of the robot vacuum cleaner (200) are connected, and a second dust collection path (148) that connects the internal space of the dust collection unit housing (141) and the internal space of the dust collection motor housing (146).

[0424] The first dust collection channel (147) can connect the dust bin (220) of the robot vacuum cleaner (200) and the internal space of the dust collection housing (141). The first dust collection channel (147) can connect the dust passage hole (123a) of the seating portion (120) and the internal space of the dust collection housing (141). The first dust collection channel (147) can be formed along a direction intersecting the vertical direction. For example, the first dust collection channel (147) can be formed close to the horizontal direction. The first dust collection channel (147) can be a space formed towards the rear from the dust passage hole (123a), or a channel formed by bending toward the side from the dust passage hole (123a) to allow dust and air to flow. Dust inside the dust bin (220) of the robot vacuum cleaner (200) can move into the internal space of the dust collection housing (141) through the first dust collection channel (147).

[0425] The second dust collection channel (148) can connect the internal space of the dust collection unit housing (141) and the internal space of the dust collection motor housing (146). The second dust collection channel (148) can be formed along a direction intersecting the vertical direction. For example, the second dust collection channel (148) can be formed close to the horizontal direction.

[0426] In this case, in the present invention, the first dust collection channel (147) and the second dust collection channel (148) may be formed at different heights. That is, the first dust collection channel (147) and the second dust collection channel (148) may be arranged in a stacked structure. At least a portion of the first dust collection channel (147) may be positioned above the second dust collection channel (148).

[0427] With this configuration, multiple Euros can be arranged close to the horizontal direction to lower the overall height, and at the same time, by stacking them, the width in the left and right directions and the overall volume of the robot vacuum cleaner station (100) can be minimized.

[0428] The air circulation unit (125) can guide the air discharged from the dust collection motor (145) to the robot vacuum cleaner (200).

[0429] The air recirculation section (125) may be composed of a recirculation path (125a) and an air recirculation port (125b).

[0430] The reflux channel (125a) can provide a channel through which air discharged from the dust collector motor (145) flows. The reflux channel (125a) can be formed through the dust collector motor housing (146) and the base (121). Specifically, one side of the reflux channel (125a) may be a space formed by combining the dust collector motor support (146c) and the dust collector motor upper housing (146a). Additionally, the other side of the reflux channel (125a) may be positioned inside the base body (121a). For example, the reflux channel (125a) may be a space formed between the upper surface and the lower surface of the base body (121a).

[0431] Accordingly, one side of the reflux channel (125a) can pass through the dust collection motor housing (146). Additionally, the other side of the reflux channel (125a) can pass through the lower side of the base (121). Along with this, at least a portion of the reflux channel (125a) can be positioned below the robot vacuum cleaner (200) mounted on the upper side of the base body (121a).

[0432] The reflux channel (125a) can be connected to the dust collection motor (145) via a channel. One end of the reflux channel (125a) can be in communication with the internal space of the dust collection motor housing (146), and the other end of the reflux channel (125a) can be in communication with the air reflux port (125b).

[0433] The reflux channel (125a) may be a channel formed along a direction intersecting the vertical direction. For example, the reflux channel (125a) may be a channel formed along a horizontal direction inside the housing (110).

[0434] At this time, at least a portion of the reflux channel (125a) may be positioned below the first dust collection channel (147). That is, the reflux channel (125a) may be positioned to pass below the first dust collection channel (147). Thus, the flow directions of the air flowing through the first dust collection channel (147) and the air flowing through the reflux channel (125a) may intersect each other in a horizontal plane.

[0435] Additionally, at least a portion of the reflux channel (125a) may be positioned above the second dust collection channel (148). That is, the reflux channel (125a) may be positioned to pass over the second dust collection channel (148).

[0436] Through this, the first dust collection channel (147), the second dust collection channel (148), and the recirculation channel (125a) can be arranged vertically (stacked) within a limited height to maximize space efficiency.

[0437] In addition, by utilizing the surplus space inside the base (121) to form a recirculation path (125a), the height of the robot vacuum cleaner station (100) can be prevented from increasing, and since no separate space is required for the path to be formed, space efficiency can be maximized.

[0438] An air recirculation port (125b) may be formed in the base (121). An air recirculation port (125b) may be formed in the agitator receiving portion (121d). At this time, the suction portion (211) of the robot vacuum cleaner (200) may be positioned above the agitator receiving portion (121d). Accordingly, the recirculation channel (125a) can discharge air to the lower side of the suction portion (211), and the air passing through the recirculation channel (125a) can flow into the suction portion (211) positioned immediately above it.

[0439] Accordingly, the reflux path (125a) according to the embodiment of the present invention can guide the air discharged from the dust collection motor (145) to the suction part (211) of the robot vacuum cleaner (200).

[0440] The reflux path (125a) guides the air discharged from the dust collection motor (145) to the suction part (211) of the robot vacuum cleaner (200) without discharging it to the outside, thereby creating a structure in which the air continuously circulates between the robot vacuum cleaner (200) and the robot vacuum cleaner station (100). As a result, the heat discharged from the dust collection motor (145) is not discharged to the kitchen cabinet (2) but is recirculated back into the interior of the robot vacuum cleaner (200), thus preventing damage to the interior of the kitchen cabinet (2).

[0441] Air passing through the dust collection motor (145) is discharged into the receiving space (S) through the air return port (125b), and the air discharged into the receiving space (S) can be recirculated into the suction part (211) due to the suction force of the dust collection motor (145). Accordingly, air sucked from the dust bin (220) by the suction force of the dust collection motor (145) can be discharged into the receiving space (S) after flowing in sequence through the dust passage hole (123a), the first dust collection path (147), the dust collection housing (141), the second dust collection path (148), the dust collection motor (145), the return path (125a), and the air return port (125b).

[0442] At this time, the dust collection motor (145) can be driven together with the suction motor (not shown) of the robot vacuum cleaner (200). Since the air exhausted through the air circulation port (125b) is sucked into the suction part (211) by the suction force of the suction motor (not shown) in addition to the dust collection motor (145), it has the effect of improving dust collection efficiency.

[0444] Sterilization module

[0445]

[0446] A robot vacuum cleaner station (100) according to one embodiment of the present invention may further include a sterilization module (150). The sterilization module (150) may be coupled to a dust collection housing (141).

[0447] In a robot vacuum cleaner station (100) according to one embodiment of the present invention, a sterilization module (150) can sterilize a dust bag (143). Specifically, the sterilization module (150) can irradiate light onto the dust bag (143).

[0448] The sterilization module (150) may include a light source that emits sterilization light and a protective panel positioned below the light source to protect the light source.

[0449] Here, the light source may include at least one light-emitting diode (LED) capable of emitting sterilizing light having a sterilizing power capable of eliminating bacteria. The sterilizing light emitted by the light source may have a wavelength that varies depending on the type of light-emitting diode.

[0450] For example, the light source may be a light-emitting diode that emits ultraviolet light with a wavelength range of UV-C. Ultraviolet light is classified into UV-A (315nm–400nm), UV-B (280nm–315nm), and UV-C (200nm–280nm) depending on the wavelength, and among these, ultraviolet light in the UV-C region can inhibit the proliferation of microorganisms by damaging their DNA double helix.

[0451] Meanwhile, the sterilization module (150) can be placed on the upper inner surface of the dust collection housing (141). The sterilization module (150) can irradiate light downwards. Through this, even if dust is present inside the dust bag (143), it sinks downwards due to gravity, so light can be irradiated inside the dust bag (143) without being affected by the presence of dust.

[0452]

[0453] Meanwhile, a sterilization module (150) according to another embodiment of the present invention can supply hot air to a dust bag (143).

[0454] The sterilization module (150) may include a fan that generates airflow, a heater that supplies heat to the air flowing into the dust collection housing (141), and a duct that guides the hot air into the dust collection housing (141).

[0455] The hot air supplied from the sterilization module (150) passes through the dust collection housing (141) and the dust bag drawer (144) to supply heat to the dust bag (143) and can sterilize insects and microorganisms.

[0456]

[0457] Mop washing section

[0458]

[0459] Referring to FIGS. 26 to 30, the mop washing unit (160) of the robot vacuum cleaner station (100) according to an embodiment of the present invention is described as follows.

[0460] A robot vacuum cleaner station (100) according to an embodiment of the present invention may include a mop washing unit (160). The mop washing unit (160) supplies washing water to the mop (242) of the robot vacuum cleaner (200) coupled to the mounting unit (120) to wash the mop (242), and can drain the wastewater after washing the mop (242).

[0461] The mop washing unit (160) may include a washing water supply unit that mixes a liquid containing detergent with purified water and discharges it to the upper side of the washing plate (122). The washing water supply unit may include a regulator (161), a mixing chamber (162), a detergent container (163), a branching path (164), and a washing water nozzle (165).

[0462] At this time, the detergent container (163) and the wastewater container (166) can be accommodated in the space formed between the inner wall (124) and the outer wall (111) of the housing. The detergent container (163) can be placed on the lower side of the space between the inner wall (124) and the outer wall (111) of the housing, and the wastewater container (166) can be placed on the upper side of the detergent container (163).

[0463] The water supply pipe of the kitchen cabinet (2) is connected to a regulator (161) so that the flow rate supplied from the water supply pipe can be regulated. Additionally, some of the purified water that has passed through the regulator (161) can be supplied to the water tank (230) of the robot vacuum cleaner (200) through the water supply nozzle (123c), and the remainder can be supplied to the mixing chamber (162).

[0464] Additionally, the liquid containing the detergent stored in the detergent container (163) can be supplied to the mixing chamber (162) through the flow force of the pump. The detailed structure of the detergent container (163) will be described later.

[0465] The mixing chamber (162) is provided with a space in which a liquid containing detergent and purified water can be introduced and mixed, and can discharge washing water mixed with detergent and purified water. This mixing chamber (162) may be provided with a purified water inlet (162a), a detergent inlet (162b), and a branch flow path connector (162c).

[0466] The mixing chamber (162) is provided inside the housing (110) and may be positioned further back than the seating portion (120). At this time, a flow path (161a) through which purified water flows in from the regulator (161) may be connected to the purified water inlet (162a). Additionally, a flow path (163a) through which liquid containing detergent flows in from the detergent container (163) may be connected to the detergent inlet (162b). Accordingly, the pumps of the regulator (161) and the detergent container (163) can operate for a certain period of time to flow a preset amount of purified water and detergent into the mixing chamber (162).

[0467] Meanwhile, the branch flow path connector (162c) can be connected to the branch flow path (164). The branch flow path (164) can supply washing water mixed with purified water and detergent to each of the pair of washing water nozzles (165).

[0468] The branched flow path (164) may be formed in a shape where one pipe is branched into two, and at this time, one end of the branched path may be connected to one of a pair of washing water nozzles (165), and the other end of the branched path may be connected to the other of a pair of washing water nozzles (165).

[0469] A pair of wash water nozzles (165) may be spaced apart. At this time, the pair of wash water nozzles (165) may be positioned symmetrically to each other.

[0470] Additionally, the washing water nozzle (165) is connected to a branching channel (164) to allow washing water to flow into it and discharge washing water onto the washing plate (122). The washing water nozzle (165) can discharge washing water onto the upper surface of the washing plate (122) through the washing water discharge port (165a). The washing water discharge port (165a) can be opened in a direction facing the upper surface of the rag (242) placed on the washing plate (122). More specifically, the washing water discharge port (165a) formed in the washing water nozzle (165) can discharge washing water toward the washing protrusion (122a) of the washing plate (122).

[0471] A washing water nozzle (165) may be provided on a nozzle installation wall (123d) connected to a connecting wall (123). The washing water nozzle (165) may be positioned higher than the top of the washing plate (122) so that the washing plate (122) can be detached. Accordingly, when the washing plate (122) is detached or the drawer (190) is pulled out, the washing plate (122) and the washing tank (128) do not collide with the washing water nozzle (165), and a washing water discharge space can be provided between the nozzle installation wall (123d) and the washing plate (122).

[0472] Additionally, the washing water nozzle (165) may be positioned vertically upward from a location spaced apart from the center in the width direction of the washing protrusion (122a). Specifically, when the rotation direction of the mop (242) during the mop (242) washing process is considered as one direction, the washing water nozzle (165) may be positioned in the other direction spaced apart from the center in the width direction of the washing protrusion (122a). The washing water discharge port (161c) may be positioned between the protrusion (122aa) and the washing rib (122ab), but spaced apart from the protrusion (122aa) in the direction opposite to the rotation direction of the mop (242). With this configuration, washing water can flow along the center in the width direction of the washing protrusion (122a).

[0473] The detergent container (163) includes a detergent container body (163a), a handle (163b), and a detergent container rail (163c).

[0474] The detergent container body (163a) can provide a space for storing a liquid containing detergent. For example, the detergent container body (163a) can be formed in the shape of a box with an open top.

[0475] A handle (163b) may be provided on the front of the detergent container body (163a). The handle (163b) may be provided so that a user can grip it. For example, the handle (163b) may be formed by being recessed from the front surface of the detergent container body (163a) toward the rear.

[0476] With this configuration, when a user grasps the handle (163b) and pulls it forward, the detergent container body (163a) can be pulled forward and withdrawn together. Therefore, according to the present invention, the user can easily pull the detergent container (163) forward and then supply detergent.

[0477] A detergent container rail (163c) may be formed on the detergent container body (163a). The detergent container rail (163c) can guide the movement of the detergent container body (163a).

[0478] For example, the detergent container rail (163c) may be formed in the shape of a groove or rib along the front-rear direction on the left-right side of the detergent container body (163a).

[0479] With this configuration, when a user attaches the detergent container (163) to the housing (110), it can be attached in the correct position and prevent the washing water from leaking out.

[0480] Meanwhile, although not shown, a rail may be formed on the housing (110) corresponding to the detergent container rail (163c). The rail may be formed corresponding to the shape and position of the detergent container rail (163c).

[0481] Meanwhile, an injection port (163aa) may be formed in the detergent container body (163a). A liquid containing detergent can be injected into the interior of the detergent container body (163a) through the injection port (163aa).

[0482] The detergent container (163) may include a refill cap (163d). The refill cap (163d) can open and close the injection port (163aa).

[0483] The inlet (163aa) may be positioned at the upper front of the detergent container body (163a). The inlet (163aa) may be positioned adjacent to the handle (163b). With this configuration, the user can fill the detergent through the inlet (163aa) after removing the refill cap (163d) while the detergent container body (163a) is partially withdrawn from the detergent container insertion opening (132b).

[0484] The refill cap (163d) is detachably coupled to the detergent container body (163a) and may be provided with a sealing portion (163db) that is formed to protrude from one side and inserted into the injection port (163aa). The sealing portion (163db) may support the injection port (163aa) so as to be inserted into and seal the injection port (163aa).

[0485] Additionally, the refill cap (163d) may be provided with a cap handle (163da) formed such that a portion of the rim protrudes outward. The cap handle (163da) may be positioned to protrude outward from the detergent container body (163a).

[0486] Additionally, the refill cap (163d) can be positioned suspended from the detergent container body (163a) even when the filling port (163aa) is opened after being separated from the detergent container body (163a). That is, to prevent the loss of the refill cap (163d), the refill cap (163d) may be equipped with a tether (163dc). One end of the tether (163dc) is integrally formed with the refill cap (163d), and the other end is equipped with a fastening member (163dd) to be inserted into the inside of the detergent container body (163a).

[0487] The detergent container (163) is provided with a tether insertion part (163ab), and the tether insertion part (163ab) is formed to be smaller than the fastening part (163dd) and larger than the cross-section of the tether (163dc). That is, when the tether insertion part (163ab) has a circular hole shape, its diameter is formed to be smaller than the diameter of the fastening part (163dd), and when the cross-section of the tether (163dc) is circular, it can be formed to be larger than the diameter of the cross-section of the tether (163dc).

[0488] Additionally, the detergent container body (163a) may be provided with a cap seating portion (163ac) and a handle seating portion (163ad) so that a refill cap (163d) can be assembled in the correct position. The cap seating portion (163ac) may be formed such that the circumference of the injection port (163aa) is stepped with respect to the upper surface of the detergent container body (163a), and may be formed so that a refill cap (163d) can be inserted. The handle seating portion (163ad) may be formed by extending one side of the cap seating portion (163ac) and may be formed so that a cap handle (163da) can be inserted. At this time, the handle seating portion (163ad) is provided to correspond to the position and shape of the cap handle (163da) so that the refill cap (163d) is positioned in the correct position. With this configuration, when the refill cap (163d) is attached to the detergent container body (163a), the cap handle (163da) is positioned to protrude outward from the detergent container body (163a), allowing the user to easily detach or attach the refill cap (163d).

[0489] The wastewater tank (166) can provide a space for storing the washing water used to wash the mop (242). After the washing of the mop (242) is finished, the washing water discharged onto the upper surface of the washing plate (122) can be drained into the passage hole (122b) while descending along the slope of the washing plate (122). The washing water that passes through the passage 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 (166b) through the wastewater inlet (166a) and can flow into the wastewater tank (166) by passing through the wastewater inlet path (166b). That is, the liquid that passes through the washing plate (122) can flow along the washing tank (128) and be discharged through the wastewater inlet (166a).

[0490] Meanwhile, the sewage suction channel (166b) is formed in the sewage suction pipe, and a sewage inlet (166a) is formed at one end of the sewage suction pipe, and the other end of the sewage suction pipe is connected to the sewage tank (166). At this time, the sewage suction pipe may be positioned to pass through the lower side of the outside air supply module (171). That is, the sewage suction channel (166b) may be positioned on the lower side of the outside air supply module (171). Additionally, the sewage suction channel (166b) may be positioned on the lower side of the outside air supply channel (171a).

[0491] The washing water stored in the wastewater tank (166) can be drained through the wastewater discharge path (167) to the drain pipe (25) of the kitchen cabinet (2). One end of the wastewater discharge path (167) can be connected to the wastewater tank (166), and the other end can be connected to the drain pipe (25). At this time, the washing water stored in the wastewater tank (166) can be drained through the wastewater discharge path (167) by a centrifugal pump (not shown) to the drain pipe (25).

[0492] The wastewater discharge path (167) connected to the wastewater tank (166) can be connected upstream (25b) based on the U-trap (25a) of the drain pipe (25) of the kitchen cabinet (2). This is because if the wastewater discharge path (167) is connected downstream (25c) based on the U-trap (25a) of the drain pipe (25), odors or fluid inside the drain pipe (25) may flow back into the wastewater discharge path (167).

[0493] Additionally, the mop washing unit (160) may include a check valve (not shown). The check valve can prevent fluid inside the drain pipe (25) from flowing back into the wastewater discharge path (167). The check valve may be provided at the other end of the wastewater discharge path (167) connected to the drain pipe (25).

[0494]

[0495] Mop drying section

[0496]

[0497] Referring to FIGS. 31 to 35, a robot vacuum cleaner station (100) according to one embodiment of the present invention may include a mop drying unit (170). At this time, the mop drying unit (170) can dry the mop (242) of the robot vacuum cleaner (200) that has been washed by the mop washing unit (160) or the mop (242) that is wet after a water cleaning operation is finished.

[0498] The mop drying unit (170) may include an external air supply module (171) and an air discharge unit (172).

[0499] The outside air supply module (171) can heat air from outside the housing (110) and supply it to the receiving space (S). The outside air supply module (171) may include an outside air supply path (171a), an outside air inlet (171b), an outside air discharge section (171c), a heater (171d), and a blower fan (not shown).

[0500] An external air supply channel (171a) is formed in the external air supply module (171). The external air supply channel (171a) can flow external air to the external air discharge section (171c).

[0501] The external air supply channel (171a) can connect the external space and the receiving space of the housing (110). One side of the external air supply channel (171a) can be in communication with the external space through the external air inlet (171b), and the other side of the external air supply channel (171a) can be in communication with the receiving space (S) through the external air discharge section (171c).

[0502] An external air inlet (171b) may be formed on the rear side of the housing (110). Multiple external air inlets (171b) may be formed on the rear side of the housing (110). Air from outside the housing (110) may flow into the external air supply path (171a) through the external air inlet (171b). Thus, air from outside the housing (110) may flow into the interior of the housing (110).

[0503] At least a portion of the external air discharge section (171c) may be positioned above the washing plate (122). The external air discharge section (171c) may be open in a direction facing the washing plate (122). A pair of external air discharge sections (171c) may be provided in a state where they are open downwards.

[0504] The outside air discharge section (171c) can discharge air that has passed through the outside air supply path (171a). The outside air discharge section (171c) can discharge air heated by the heater (171d). For example, an outside air discharge port may be formed in the outside air discharge section (171c).

[0505] Meanwhile, in this embodiment, the left-right diameter of the external air discharge section (171c) may become narrower as it moves forward. That is, in this embodiment, the left-right diameter of the external air discharge section (171c) may have a width at the rear end greater than the width at the front end. Through this, even if the disc-shaped mop (242) rotates during the drying process, the entire mop (242) can be dried uniformly.

[0506] Meanwhile, the outside air discharge section (171c) may be equipped with a grille that guides the direction of air discharge. Through this, it is possible to prevent heated air from being discharged in a concentrated manner at a specific location.

[0507] With the mop (242) seated on the cleaning plate (122), the external air discharge section (171c) can be opened toward the upper side of the mop (242). Thus, the external air discharge section (171c) is positioned adjacent to the mop (242) and is opened downward, allowing air discharged from the external air discharge section (171c) to flow toward the mop (242).

[0508] In particular, the external air discharge section (171c) of the present embodiment may be provided in a downwardly inclined shape as it moves toward the front of the robot vacuum cleaner station (100). Accordingly, the end from which air is discharged from the external air discharge section (171c) may be formed at a predetermined angle with respect to the ground. The angle at this time may be 90 degrees or less. Therefore, the external air discharge section (171c) can discharge air along a direction that intersects with the direction in which the flow guide surface (122c) is formed.

[0509] A blower fan (not shown) is positioned on the outside air supply path (171a) and can blow air toward the receiving space (S). When the blower fan (not shown) is driven, air introduced through the outside air inlet (171b) is heated by a heater (171d) and can be discharged into the receiving space (S) through the outside air discharge section (171c).

[0510] A heater (171d) is positioned on an outside air supply path (171a) and can heat the air flowing through the outside air supply path (171a). The heater (171d) can heat the air discharged through the outside air discharge section (171c).

[0511] The heater (171d) may include a heater housing and a heating element. In this case, the heater housing may be placed on an external air supply path (171a), and a space may be provided inside to accommodate a heating element. Additionally, the heating element may heat the air flowing into the heater housing. Thus, the air heated by the heating element is discharged into the receiving space (S) through the external air discharge section (171c) to dry the wet rag (242).

[0512] Air heated by heat discharged from the outside air supply module (171) can be discharged through the air discharge section (172).

[0513] The air exhaust section (172) may be positioned at least partially above the receiving space (S).

[0514] Air heated by heat discharged from the external air supply module (171) can supply heat to the mop (242) of the robot vacuum cleaner (200). Accordingly, moisture absorbed and remaining in the mop (242) can absorb heat from the air and vaporize. The vaporized moisture can flow within the receiving space (S). Therefore, the air within the receiving space (S) may contain vaporized moisture, and the humidity within the receiving space (S) may increase (hereinafter, the air containing vaporized moisture within the receiving space (S) may be referred to as 'moist steam').

[0515] Specifically, at least a portion of the air discharge section (172) may be placed on the upper cover (113), and the upper cover (113) may cover the upper part of the receiving space (S).

[0516] The air heated by the heat discharged from the outside air supply module (171) vaporizes the moisture in the mop (242), so the humidity is increased. Therefore, when the robot vacuum cleaner station (100) is placed at the bottom of the kitchen cabinet (2), if the steam comes into contact with various parts of the kitchen cabinet (2), such as the baseboard (26), it will have an adverse effect on the parts.

[0517] In this embodiment, the upper cover (113) covers the upper part of the receiving space (S) and the door (126) covers the front of the receiving space (S), so the upper cover (113) together with the door (126) prevents the moisture from the receiving space (S) from escaping to the outside, thereby preventing the kitchen cabinet (2) from coming into contact with the moisture.

[0518] The air exhaust section (172) may include an air intake (172a), an air exhaust duct (172b), and an exhaust fan (172c).

[0519] The air intake (172a) may be connected to the receiving space (S). The air intake (172a) may be positioned above the receiving space (S). The moisture vapor of the receiving space (S) may be discharged through the air intake (172a).

[0520] The air intake (172a) can be positioned higher than the ground than the robot vacuum cleaner (200) when the robot vacuum cleaner (200) is seated on the seating portion (120). Through this, the efficiency of sucking up rising convective steam as the mop dries can be increased.

[0521] For example, an air intake (172a) may be formed in the upper cover (113). In this case, the upper cover (113) may be formed in a shape where two or more plates are stacked, and the air intake (172a) may be formed in the lowest plate among them, and a flow path communicating with the air intake (172a) may be formed between the plates to form an air discharge duct (172b).

[0522] As another example, the air intake (172a) may be formed on a circular or square pipe-shaped air exhaust duct (172b), and the air exhaust duct (172b) may be connected to the upper cover (113).

[0523] With this configuration, when the upper cover (113) is separated, the air exhaust duct (172b) can be separated together with the upper cover (113), and when it is necessary to open the upper part of the robot vacuum cleaner station (100) for reasons such as repair, the air exhaust duct (172b) can be removed by a simple motion of lifting the upper cover (113), which has the advantage of being able to remove the air exhaust duct (172b).

[0524] The air intake (172a) may be formed in the shape of a hole on the air exhaust duct (172b). For example, the air intake (172a) may be formed in the shape of a plurality of slits formed side by side on the air exhaust duct (172b). Alternatively, the air intake (172a) may be formed in the shape of an elongated hole on the air exhaust duct (172b).

[0525] Meanwhile, multiple air intakes (172a) may be arranged at equal distances from the front end of the housing (110). For example, a pair of air intakes (172a) may be arranged at equal distances from the front end of the housing (110). That is, the air intakes (172a) may include a first intake and a second intake. In this case, the first intake may be arranged at the front left upper end of the receiving space (S), and the second intake may be arranged spaced apart from the first intake and arranged at the front right upper end of the receiving space (S).

[0526] The distance from the outside air outlet (171c) to the air intake (172a) may be greater than the distance from the outside air outlet (171c) to the mop (242). This is to prevent energy from being wasted by ensuring that the heated air discharged from the outside air outlet (171c) is not sufficiently supplied to the mop (242) and is instead sucked directly into the air intake (172a).

[0527] Additionally, the air intake (172a) may be positioned closer to the door (131) than the outside air discharge (171c). Since the air intake (172a) is positioned at the front upper part of the receiving space (S), the range of the space through which the heat discharged from the outside air discharge section (171c) flows is widened, thereby improving the drying efficiency of the mop (242). Therefore, the heat discharged through the outside air discharge section (171c) flows forward to dry the mop (242) of the robot vacuum cleaner (200), and then can be discharged through the air intake (172a).

[0528] Additionally, the air intake (172a) may be positioned above the path where the robot vacuum cleaner (200) moves within the housing (110). This prevents condensation from forming on the inner wall of the housing (110).

[0529] For example, at least a portion of the air intake (172a) may be positioned vertically above the position where the left-right width of the robot vacuum cleaner (200) is greatest when the robot vacuum cleaner (200) is seated on the seating portion (120). That is, at least a portion of the air intake (172a) may be positioned above the position where the gap between the robot vacuum cleaner (200) and a pair of inner walls (124) is narrowest. At this time, at least a portion of the air intake (172a) may be positioned in front of the cleaning plate (122).

[0530] Through this, steam generated during the drying process of the mop (242) can be prevented from flowing toward the front of the robot vacuum cleaner station (100), and moisture can be prevented from penetrating the sensor placed in front of the robot vacuum cleaner (200) and causing a malfunction.

[0531] The air exhaust duct (172b) can connect the air intake (172a) and the exhaust fan (172c) to the drain pipe (25) of the kitchen cabinet (2). The air exhaust duct (172b) can guide the steam discharged through the air intake (172a) to the drain pipe (25).

[0532] One side of the air exhaust duct (172b) is connected to the exhaust fan (172c), while the other side can be branched into multiple parts. Through this, even if only one exhaust fan (172c) is used, humid steam can be sucked in from multiple locations, so the effect of stably discharging humid steam is achieved.

[0533] The air exhaust duct (172b) may have an air exhaust passage formed therein that communicates with the air intake (172a).

[0534] The air exhaust passage may refer to a passage through which air introduced through the air intake (172a) flows. For example, the air exhaust passage may be formed by including the internal space of the air exhaust duct (172b), the internal space of the housing of the exhaust fan (172c), and the internal space of the check valve (172d). One side of the air exhaust passage may be in communication with the air intake (172a), and the other side may be in communication with the air exhaust (172e).

[0535] The exhaust fan (172c) can generate airflow from the air intake (172a) toward the drain pipe (25). The exhaust fan (172c) can generate airflow so that after the humid steam in the receiving space (S) is drawn into the air intake (172a), it can be discharged to the outside through the air discharge duct (172b).

[0536] The exhaust fan (172c) may include an exhaust fan housing, a fan motor, and an impeller. The exhaust fan housing may have an internal flow path formed to communicate with an air discharge duct (172b). When the exhaust fan motor is operated and the exhaust fan impeller rotates, air from the receiving space (S) or the housing (110) flows into the air discharge duct (172b), passes through the inside of the exhaust fan housing, and can be discharged through the air outlet (172e).

[0537] Meanwhile, in this embodiment, the exhaust fan (172c) can be combined with the outside air supply module (171). Specifically, the exhaust fan housing of the exhaust fan (172c) can be combined with the outside air supply module (171) to form a single assembly. Through this, the space occupied by the outside air supply module (171) and the air discharge section (172) can be minimized.

[0538] The exhaust fan (172c) can be positioned on the left and right sides of the outside air supply module (171). Specifically, the exhaust fan (172c) can be positioned between the dust collection motor (145) and the outside air supply module (171). Through this, components can be placed in a limited space, and a space can be secured for a flow path to be placed for discharging steam.

[0539] When the exhaust fan (172c) is driven, air in the receiving space (S) can be drawn into the air intake (172a). The air drawn into the air intake (172a) can be exhausted through the drain pipe (25).

[0540] The rag drying section (170) may include a check valve (172d) that prevents fluid inside the drain pipe (25) from flowing back into the air discharge duct (172b). The check valve (172d) may be positioned at the rear of the exhaust fan (172c). The check valve (172d) may be in communication with the internal space of the exhaust fan (172c). That is, based on the direction of air flow, the check valve (172d) may be positioned downstream of the exhaust fan (172c). An air outlet (172e) may be formed at the rear end of the check valve (172d). The check valve can prevent fluid inside the drain pipe (25) from flowing back into the air discharge section (172).

[0541] At this time, the lower end of the air outlet (172e) may be positioned along a direction perpendicular to the ground. Specifically, the air outlet (172e) may be formed in an air discharge pipe positioned along a direction perpendicular to the ground, and the air discharge pipe may be connected to a check valve. With this configuration, the fluid discharged from the air outlet (172e) is prevented from flowing backward by utilizing the property of high temperature and humidity air rising through convection.

[0542] The air exhaust section (172) can be connected downstream of the U-trap (25a) of the drain pipe (25). Specifically, the air exhaust (172e) can be connected to the drain pipe (25) through a flow path member. For example, the flow path member may be a hose. This is because if the air exhaust section (172) is connected upstream (25b) of the drain pipe (25) with respect to the U-trap (25a), the heat exhausted through the air exhaust section (172) may not pass through the drain pipe (25) due to the water accumulated in the U-trap (25a). Additionally, this is to prevent odors generated from the air exhaust section (172) from flowing back along the drain pipe (25) and spreading into the kitchen.

[0543] The wet steam discharged through the air intake (172a) and passing through the exhaust fan (172c) can be discharged to the outside of the housing (110) along the flow path while passing through the air outlet (172e).

[0544] At this time, the flow path member can be connected to the drain pipe (25) by penetrating either side of the outer wall. With this configuration, the connection direction of the flow path member can be selected according to the installation environment of the robot vacuum cleaner station (100) of the present invention, thus providing the advantage of easy installation and management.

[0545]

[0546] drawer

[0547]

[0548] When a charging station for a robot vacuum is placed at the bottom of a kitchen cabinet, it minimizes external exposure, which can provide an interior design effect. However, there is a limitation in that if the robot vacuum breaks down while it is inside the kitchen cabinet or if the charging station for the robot vacuum breaks down, it may be difficult for the user to take it out and repair it. To solve this, the present invention may add a drawer (190) to the robot vacuum station (100).

[0549] In this regard, FIG. 36 illustrates a drawing for explaining the state in which a drawer is withdrawn from a robot vacuum cleaner station according to an embodiment of the present invention.

[0550] Referring to FIG. 36, a drawer (190) of a robot vacuum cleaner station (100) according to one embodiment of the present invention is described as follows.

[0551] A robot vacuum cleaner station (100) according to one embodiment of the present invention may further include a drawer (190) that is drawn out of a housing (110).

[0552] The drawer (190) can be moved relative to the housing (110). For example, the housing (110) is fixedly connected to the kitchen cabinet (2), and the drawer (190) can be pulled forward from the housing (110).

[0553] At this time, the drawer (190) can be pulled out with the seating portion (120) provided inside. With this configuration, when the drawer (190) is pulled out, the seating portion (120) and / or the robot vacuum cleaner (200) can be pulled out from the kitchen cabinet (2).

[0554] At this time, when the drawer (190) is withdrawn from the housing (110) while the door (131) is closed to the entrance (127), the upper cover (113) may be exposed to the outside. At this time, when the upper cover (113) is disassembled, the robot vacuum cleaner (200) may be exposed to the outside.

[0555] Accordingly, according to the present embodiment, when maintenance such as repair or cleaning is required of the robot vacuum cleaner station (100), the user can easily pull out the mounting portion (120) and / or the robot vacuum cleaner (200) through the drawer (190) to expose the internal components of the robot vacuum cleaner station (100) or the robot vacuum cleaner (200).

[0556] Meanwhile, a drawer (190) according to one embodiment of the present invention may be drawn out with a dust collection unit (140) provided inside. At this time, the drawing direction of the drawer (190) may be parallel to the drawing direction of the dust bag drawer (144).

[0557] Additionally, a drawer (190) according to one embodiment of the present invention can be withdrawn together with a mop washing unit (160). Specifically, the drawer (190) can be withdrawn together with a detergent container (163). At this time, the direction in which the drawer (190) is withdrawn can be parallel to the withdrawal direction of the detergent container (163).

[0558] With this configuration, the robot vacuum cleaner station (100) according to one embodiment of the present invention may be provided with the drawer (190), dust bag drawer (144), and detergent container (163) all having parallel drawing directions.

[0559] Therefore, the user can easily recognize the direction of withdrawal of the components of the robot vacuum cleaner station (100) of the present invention, and can easily withdraw them for repair and maintenance.

[0560] The drawer (190) includes a drawer side wall (191), a fitting part (192), and a drawer rail (193).

[0561] The drawer side wall (191) is provided to be movable relative to the outer wall surface of the housing (110). For example, a pair of drawer side walls (191) may be positioned to face a pair of outer walls of the housing (110).

[0562] At this time, a pair of drawer side walls (191) may be positioned on the inner side of the robot vacuum cleaner station (100) rather than on the outer wall of a pair of housings (110). That is, a pair of drawer side walls (191) may be positioned closer to the seating portion (120) than on the outer wall of a pair of housings (110).

[0563] Meanwhile, a dust collection unit (140) and / or a mop washing unit (160) may be disposed between the drawer side wall (191) and the seating unit (120).

[0564] With this configuration, the dust collection unit (140) and the mop washing unit (160) can be arranged by utilizing the minimum horizontal space.

[0565] A drawer rail (193) is positioned on a drawer side wall (191) and can guide the movement of the drawer side wall (191). The drawer rail (193) may be fixedly coupled to or integrally formed with the drawer side wall (191) and may be coupled to a rail installed on the outer wall (111) of the housing (110) to guide the movement path of the drawer side wall (191). Meanwhile, although the present invention describes that a rail is provided on the drawer (190) and the housing (110), it is not necessarily limited to the form of a rail, and may include all forms such as a roller, guide groove, or guide rib that can replace the rail.

[0566]

[0569] FIG. 37 discloses a block diagram for explaining the control configuration in a vacuum cleaner station according to an embodiment of the present invention.

[0570] Referring to FIG. 37, the control configuration of the robot vacuum cleaner station (100) of the present invention is described as follows.

[0571] A vacuum cleaner station (100) according to an embodiment of the present invention further includes a control unit (300) that controls a seating unit (120), a dust collection motor (145), a mop washing unit (160), and a mop drying unit (170).
