Description

Robot vacuum cleaner station

[0001] The present invention relates to a robot vacuum cleaner station, and more specifically, to a built-in station capable of collecting dust from the dustbin of a robot vacuum cleaner, washing the mop of a robot vacuum cleaner, and drying the mop when a robot vacuum cleaner is coupled thereto.

[0002] With the recent advancement of industrial technology, robot vacuum cleaners are being developed that drive and clean areas requiring cleaning on their own without user intervention.

[0003] 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.

[0004] 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 wipes the floor surface while containing moisture, thereby effectively removing debris attached to the floor surface. In addition, there are robot vacuum cleaners equipped with both an agitator and a mop.

[0005] 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.

[0006] 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.

[0007] 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.

[0008] In this regard, Chinese Utility Model Registration CN 218922467 U discloses a cleaning station in which a robot vacuum cleaner is coupled to the lower side of a washing machine to charge the robot vacuum cleaner, collect dust, and clean the mop of the robot vacuum cleaner.

[0009] 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.

[0010] 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.

[0011] 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.

[0012] In addition, since the space for the robot vacuum cleaner to enter and exit the aforementioned vacuum cleaner station is always open, there are limitations in that dust may scatter during the process of collecting dust in the robot vacuum cleaner's dustbin and wastewater may leak during the process of washing the robot vacuum cleaner's mop.

[0013] 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.

[0128] Referring to FIGS. 6 to 9, the structure of the robot vacuum cleaner (200) is described as follows.

[0129] 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.

[0130] 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.

[0131] 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.

[0132] 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.

[0133] 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).

[0134] 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).

[0135] 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.

[0136] In an embodiment of the present invention, the body (210) may be formed in a shape in which the width (or diameter) in the horizontal direction (in the direction parallel to X and Y) is greater than the height in the vertical direction (in the direction parallel to Z). 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).

[0137] When viewed from above or below, the body (210) can be made in various shapes, such as circular, elliptical, or square.

[0138] 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.

[0139] 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.

[0140] 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.

[0141] 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).

[0142] 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 air circulation port (125b). At this time, a filter may be placed in the air circulation port (125b).

[0143] 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 air circulation port (125b) through the exhaust path.

[0144] 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.

[0145] 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.

[0146] 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).

[0147] 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).

[0148] The dustbin (220) may be equipped to suck in external dust and air and store dust.

[0149] 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.

[0150] 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.

[0151] 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.

[0152] 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).

[0153] 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).

[0154] 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).

[0155] 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).

[0156] 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.

[0157] 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).

[0158] 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.

[0159] 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.

[0160] 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.

[0161] 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).

[0162] The rotating cleaning unit (240) includes a rotating plate (241) and a mop (242).

[0163] 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.

[0164] 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.

[0165] 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 (B) or may be inclined with respect to the bottom surface (B). 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.

[0166] A pair of rotating plates (241) can be symmetrical to each other.

[0167] The mop (242) can be attached to the lower side of the rotating plate (241) so as to face the bottom surface (B).

[0168] 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 bottom surface (B) or may be inclined with respect to the bottom surface (B).

[0169] 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).

[0170] 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.

[0171] 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.

[0172] 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).

[0173] 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).

[0174] The wheel (260) is provided on the body (210) and can roll on the bottom surface.

[0175] 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.

[0176] 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.

[0177] 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.

[0178] 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.

[0179] 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.

[0180] 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).

[0181] 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).

[0182] In addition, the battery can supply power to the sensor unit (not shown) and the control unit (not shown).

[0183] 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.

[0184] Robot vacuum cleaner station

[0185] FIG. 10 shows a perspective view for explaining a robot vacuum cleaner station according to an embodiment of the present invention, and FIG. 11 shows a plan view of FIG. 10.

[0186] Referring to FIGS. 10 and FIGS. 11, the robot vacuum cleaner station (100) of the present invention is described as follows.

[0187] 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).

[0188] The robot vacuum cleaner station (100) may include a housing (110).

[0189] 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.

[0190] The housing (110) may have a space formed therein to accommodate a seating portion (120), a dust collection channel (147, 148), a dust collection portion (140), a dust collection motor (145), a mop washing portion (160), a mop drying portion (170), and a circulation channel.

[0191] 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.

[0192] 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.

[0193] For example, a pair of outer walls (111) may be installed on the lower side of the kitchen cabinet (2) at a predetermined interval. For another example, the housing (110) may further include a bottom surface facing the kitchen floor, and the pair of outer walls may be connected through the bottom surface. For yet another example, the housing (110) may further include a lower surface facing the kitchen floor and an upper surface facing the lower plate (23) of the kitchen cabinet (2), and the upper and lower ends of the pair of outer walls may be connected to each other through the lower surface and the upper surface. 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. For yet another example, the housing (110) may further include the lower surface, the upper surface, and a rear surface facing the wall of the building.

[0194] With this configuration, components of a robot vacuum cleaner station (100) can be accommodated inside the housing (110) (between a pair of outer walls).

[0195] 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).

[0196] 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 (126) is provided relative to the interior of the robot vacuum cleaner station (100).

[0197] 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).

[0198] 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.

[0199] That is, the outer walls of the robot vacuum cleaner station (100) can be positioned on the left and right sides, respectively.

[0200] 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.

[0201] Through this, the robot vacuum cleaner station (100) and the robot vacuum cleaner (200) can be minimized from being exposed to the outside.

[0202] 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.

[0203] With this configuration, the outer wall (111) of the housing (110) may include a left side (111c) and a right side (111d). The left side (111c) of the housing (110) refers to an outer surface positioned on the left when viewed from the inside of the robot vacuum cleaner station (100) looking forward, and the right side (111d) of the housing (110) refers to an outer surface positioned on the right when viewed from the inside of the robot vacuum cleaner station (100) looking forward.

[0204] Additionally, the housing (110) may have a front surface, which is an outer surface positioned at the front, and the front surface may be formed to be open. That is, the housing (110) may be installed so that a drawer (190), which will be described later, can be pulled out, and the drawer (190) can be pulled out through the open space of the front surface of the housing (110).

[0205] The housing (110) may have a rear surface (111b) positioned opposite the front surface. The rear surface (111b) refers to an outer surface positioned at the rear and may be positioned opposite the wall of the building.

[0206] Additionally, the housing (110) may include an upper side (113) that is covered by a kitchen cabinet (2). The housing (110) may include a lower side that is covered by the kitchen floor. The upper side (113) and the lower side of the housing (110) may refer to outer sides positioned on the upper and lower sides, and may be positioned facing each other. Additionally, the housing (110) may be formed with an open lower side.

[0207] The front side, rear side (111b), left side (111c), right side (111d), lower side, and upper side (113) of the housing (110) can form the exterior of the robot vacuum cleaner station (100) together with the doors (126, 1126, 2126) to be described later.

[0208] Meanwhile, although not shown, 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, and a space through which a hose through which moisture generated during the drying process of the mop (242) is discharged. For example, a space through which the above hoses can pass may be formed in at least one of the outer wall, rear side, and upper side of the housing (110).

[0209] Settling part (120)

[0210] As illustrated in FIG. 11, the robot vacuum cleaner station (100) may include a seating portion (120).

[0211] 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).

[0212] The seating portion (120) can be placed inside the housing (110).

[0213] At this time, according to the embodiment, the seating portion (120) may be provided so as to be pulled out from the housing (110) through the drawer (190).

[0214] With this configuration, if the mounting part (120) needs to be cleaned or repaired, or if some parts need to be replaced, the user can easily pull out the mounting part (120) for maintenance.

[0215] An entrance (127) into which a robot vacuum cleaner (200) is inserted may be formed in the seating portion (120). The entrance (127) may refer to a space formed on the front surface of the robot vacuum cleaner station (100).

[0216] 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, and the top of the entrance may be the same as the lower surface of the lower plate (23) of the kitchen cabinet (2) or the top of the housing (110).

[0217] Additionally, the entrance (127) is formed such that its width in the left-right direction is greater than the maximum width of the robot vacuum cleaner (200). At this time, 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 form a boundary with the dust collection unit (140) and the mop washing unit (160). If either the dust collection unit (140) or the mop washing unit (160) is absent, it is also possible for the outer wall of the housing (110) to serve as the boundary.

[0218] At this time, the entrance (127) can be opened and closed by a door (126, 1126, 2126). The door (126, 1126, 2126) will be described in detail below.

[0219] The seating portion (120) may include a receiving space (S), a base (121), a connecting wall (123), and an inner wall (124).

[0220] 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).

[0221] The base (121) can be positioned so that the robot vacuum cleaner station (100) contacts the floor surface and 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 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).

[0222] 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).

[0223] The base body (121a) may be formed such that the width (or diameter) in the horizontal direction (parallel to X and Y) is greater than the height in the vertical direction (parallel to Z). Due to this structure, the robot vacuum cleaner station (100) can be stably supported on the floor surface.

[0224] A circulation path may be provided inside the base body (121a). Accordingly, air discharged from the dust collection motor (145) can flow through the circulation path formed inside the base body (121a) and be exhausted to the air return port (125b).

[0225] The inclined section (121b) can be placed at the entrance where the robot vacuum cleaner (200) climbs from the base body (121a).

[0226] 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 be connected such that the front end of the entrance side is not at a height difference from the ground, but may have an upward slope toward the front of the direction in which the robot vacuum cleaner (200) enters. At this time, the front of the direction in which the robot vacuum cleaner (200) enters refers to the rear when viewed from the robot vacuum cleaner station (100). Thus, the robot vacuum cleaner (200) can easily step up from the ground to the robot vacuum cleaner station (100).

[0227] A wheel guide section (121ba) may be provided in the inclined section (121b).

[0228] 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.

[0229] An auxiliary wheel guide (121bb) may be provided in the inclined section (121b).

[0230] 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).

[0231] 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).

[0232] 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).

[0233] 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).

[0234] At least a portion of the agitator (250) of the robot vacuum cleaner (200) can be accommodated in the agitator receiving portion (121d). Specifically, the agitator receiving portion (121d) can provide a space in which the lower portion of the agitator (250) of the robot vacuum cleaner (200) is accommodated while the wheel (260) of the robot vacuum cleaner (200) is seated in the wheel coupling portion (121c).

[0235] 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 lower 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).

[0236] The agitator receiving portion (121d) may include a recess (121da) and a protrusion (121db).

[0237] The recess (121da) can be formed to be recessed from the base (121). The recess (121da) can form a receiving space in which at least a portion of the agitator (250) is received. In this way, at least a portion of the agitator (250) can be received in the receiving space of the recess (121da) while the wheel (260) of the robot vacuum cleaner (200) is seated on the wheel coupling portion (121c).

[0238] The receiving space of the recess (121da) can be connected to the receiving space (S) of the seating portion (120).

[0239] The protrusion (121db) may be formed to protrude from the base (121). The protrusion (121db) may be positioned along the edge of the recess (121da). Additionally, when the agitator (250) is received in the receiving space of the recess (121da), the protrusion (121db) may be positioned at a predetermined distance from the body (210) of the robot vacuum cleaner (200).

[0240] The protrusion (121db) can guide air discharged through the air circulation port (125b) to the suction port (211) of the robot vacuum cleaner (200). In this way, air discharged into the receiving space of the recess (121da) can be guided to the suction port (211) of the robot vacuum cleaner (200) by the protrusion (121db).

[0241] 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 circulation path. The recess (121da) and the circulation 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).

[0242] 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.

[0243] 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 connecting wall (123) to allow air from outside the housing (110) to flow into the interior. The dust passage hole (123a) may be in communication with the dust bin (220) of the robot vacuum cleaner (200). The dust passage hole (123a) may be in communication with the dust outlet (221) of the dust bin (220) of the robot vacuum cleaner (200). The dust passage hole (123a) may be formed in a hole shape corresponding to the shape of the dust bin (220) so that dust from the dust bin (220) flows into the dust collection portion (140). The dust passage hole (123a) may be formed corresponding to the shape of the dust outlet (221) of the dust bin (220). 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 exhaust section (125) after flowing through the dust collection passage (147, 148).

[0244] 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).

[0245] The robot vacuum cleaner station (100) may further include a water supply nozzle (123c).

[0246] 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 inlet is configured to be connected to the water tank (230) of the robot vacuum cleaner (200). The water supply nozzle (123c) can supply water supplied from the water supply pipe of the kitchen cabinet (2) to the storage space inside the water tank (230) of the robot vacuum cleaner (200).

[0247] 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). The height of the inner walls (124) may be formed to correspond to the height of the pedestal (21). Specifically, the height of the inner walls (124) may be formed to be the same as the height of the pedestal (21).

[0248] Meanwhile, various components such as dust collection channels (147, 148), dust collection unit (140), dust collection motor (145), detergent container (163), and wastewater container (164) may be arranged on the outer side of the inner wall (124). Specifically, the dust collection unit (140), detergent container (163), and wastewater container (164) may be accommodated in the space between the inner wall (124) and the outer wall of the housing (110).

[0249] 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 of the housing (110). The left-right width of the dust collector (140) and the detergent container (163) can be formed to correspond to the distance between the inner wall (124) and the outer wall of the housing (110).

[0250] The washing tank (128) is configured to accommodate the washing plate (122), which will be described later. The washing tank (128) may be positioned at the rear side of the base body (121a). The washing tank (128) may be formed to correspond to the washing plate (122) so that the washing plate (122) can be fitted therein.

[0251] 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).

[0252] A protrusion (122a) and a drain hole (122b) may be formed on the cleaning plate (122). When the driving unit of the rotating cleaning unit (240) is driven while the mop (242) of the robot vacuum cleaner (200) is seated on the cleaning plate (122), the mop (242) rotates. At this time, when the mop (242) rotates while cleaning water is supplied to the cleaning plate (122), the mop (242) can be cleaned by friction with the stationary protrusion (122a).

[0253] Additionally, the washing plate (122) may be formed to slope downward toward the center. Thus, after washing the rag (242), the washing water flowing along the sloped washing plate (122) can drain through the drain hole (122b) into the space formed between the washing plate (122) and the washing tank (128).

[0254] Dust collector (140)

[0255] FIGS. 12 and 13 show side views illustrating a dust collection unit of a robot vacuum cleaner station according to an embodiment of the present invention, and FIG. 14 shows a cross-sectional view illustrating a dust collection path of a robot vacuum cleaner station according to an embodiment of the present invention.

[0256] Referring to FIGS. 12 and 17, the dust collection unit (140), dust collection module (150), and dust collection path (147, 148) are described as follows.

[0257] 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). At this time, the receiving space (S) can be placed inside the seating unit (120).

[0258] The dust collection unit (140) may include a dust collection unit housing (141), a dust bag (not shown), a filter (142), and a dust bag drawer (144).

[0259] The dust collection housing (141) can form a space inside which a dust bag (not shown), a filter (142), and a dust bag drawer (144) can be accommodated.

[0260] 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 (not shown) 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).

[0261] 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 (not shown) is attached to the dust collection housing (141), the dust bag (not shown) may be in communication with the first dust collection path (147) inside the dust collection housing (141).

[0262] A dust bag (not shown) may refer to a dust bag that collects dust sucked in from inside the dust bin (220) of the robot vacuum cleaner (200) by a dust collection motor (145). The dust bag (not shown) may be detachably connected to a dust collection housing (141). Thus, the dust bag (not shown) may be separated from the dust collection housing (141) and discarded, and a new dust bag (not shown) may be connected to the dust collection housing (141). That is, the dust bag (not shown) may be defined as a consumable part.

[0263] A dust bag (not shown) can be provided so that when suction force is generated by a dust collection motor (145), its volume increases and dust is contained inside.

[0264] To this end, the dust bag (not shown) may 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 (not shown) may be made of a non-woven fabric material and may have a cuboid shape corresponding to the shape of the dust collection housing (141) when the volume is increased.

[0265] Alternatively, the dust bag (not shown) may be formed from a non-permeable material. For example, the dust bag (not shown) may include a roll vinyl (not shown). With such a configuration, when the dust bag (not shown) is sealed or bonded, it is possible to prevent dust or odors captured inside the dust bag (not shown) from leaking out of the dust bag (not shown). At this time, the dust bag (not shown) may be mounted in the dust collection housing (141) through a dust bag cartridge (not shown). If necessary, the dust bag (not shown) may be replaced through the dust bag cartridge.

[0266] A filter (142) may be placed between the dust collection housing (141) and the second dust collection path (148). The filter (142) may be placed at the outlet (141b). The filter (142) may be a pre-filter or a HEPA filter. Air passing through a dust bag (not shown) may pass through the filter (142) and flow into the second dust collection path (148).

[0267] A filter (142) may be placed between the dust collection housing (141) and the second dust collection path (148). The filter (142) may be placed at the outlet (141b). The filter (142) may be a pre-filter or a HEPA filter. Air passing through a dust bag (not shown) may pass through the filter (142) and flow into the second dust collection path (148).

[0268] A dust bag drawer (144) is coupled to be pullable out of the dust collection housing (141), and a dust bag (not shown) can be accommodated inside.

[0269] This dust bag drawer (144) can be positioned between the other side of the left and right sides of the housing (110) and the seating portion (120). Specifically, the dust bag drawer (144) can be positioned between the left side (111c) of the housing (110) and the seating portion (120).

[0270] At this time, referring to FIG. 17, the dust bag drawer (144) includes a dust bag drawer body (144a), a handle (144d), and a drawer rail (144e).

[0271] The dust bag drawer body (144a) may provide a space for a dust bag (not shown) to be attached 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) and an outlet (144c) may be formed at the rear so as to be in communication with the first dust collection channel (147) and the second dust collection channel (148).

[0272] For example, the dust bag drawer body (144a) may be formed with different left-right widths on the upper side and lower side. For example, the left-right width on the upper side of the dust bag drawer body (144a) may be formed to be larger than the left-right width on the lower side. That is, the interior of the dust bag drawer body (144a) may be formed in a stepped manner. Through this, the upper space where the dust bag (not shown) is provided can be maximized, and a flow path can be formed to facilitate the air passing through the dust bag (not shown) escaping to the lower side.

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

[0274] The dust bag drawer (144) may be connected to the second dust collection path (148) through an outlet (144c) formed on the lower side. The outlet (144c) may be configured to guide air passing through the dust bag drawer (144) to the second dust collection path (148). The outlet (144c) may be positioned at a different height from the inlet (144b). The outlet (144c) may be positioned lower than the inlet (144b). The outlet (144c) may be connected to the internal space of the dust bag drawer (144) and the second dust collection path (148). Thus, air that has been filtered of dust while passing through a dust bag (not shown) may move to the second dust collection path (148) via the outlet (144c).

[0275] 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 include a pair of connecting parts hinged to the front surface of the dust bag drawer body (144a), and a gripping part formed by connecting the pair of connecting parts so that a user can grip it.

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

[0277] Drawer rails (144e) may be formed on the left and right sides of the dust bag drawer body (144a). The drawer rails (144e) can guide the movement of the dust bag drawer body (144a).

[0278] For example, the drawer rail (144e) may be formed in the shape of a groove or rib along the front-rear direction on the left-right side of the dust bag drawer body (144a).

[0279] With this configuration, when a user attaches the dust bag drawer (144) to the dust collection housing (141), it can be attached in the correct position, and the dust collection unit (140), the first dust collection path (147), and the second dust collection path (148) can be connected in the correct position to reduce flow loss.

[0280] Meanwhile, a rail (141a) may also be formed on the inner surface of the dust collection housing (141) corresponding to the drawer rail (144e). The rail (141a) of the dust collection housing (141) may be formed corresponding to the shape and position of the drawer rail (144e). For example, if the drawer rail (144e) is formed in a groove shape, the rail (141a) of the dust collection housing (141) may be formed in a rib or protruding jaw shape.

[0281] Euro structure

[0282] Referring to FIGS. 12 to 17, the dust collection module (150) and dust collection path (147, 148) are described as follows.

[0283] The robot vacuum cleaner station (100) may include dust collection channels (147, 148). The dust collection channels (147, 148) may refer to channels through which air sucked in through the dust passage hole (123a) flows through the dust collection unit (140) to the dust collection motor (145).

[0284] Specifically, the dust collection path (147, 148) may include a first dust collection path (147) that connects the dust bin (220) and the dust collection unit (140) 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 dust collection unit (140) and the dust collection motor (145).

[0285] The first dust collection channel (147) can connect the dust bin (220) of the robot vacuum cleaner (200) and the dust collection unit (140). The first dust collection channel (147) can connect the dust bin (220) of the robot vacuum cleaner (200) and the dust collection unit (140). The first dust collection channel (147) can connect the dust passage hole (123a) of the seating unit (120) and the dust collection unit (140). The first dust collection channel (147) may refer to the space between the dust bin (220) of the robot vacuum cleaner (200) and the dust collection unit (140). The first dust collection channel (147) may be formed close to the horizontal direction. The first dust collection channel (147) may be a space formed towards the rear from the dust passage hole (123a), or it may be a channel formed by bending toward the side from the dust passage hole (123a) so that dust and air can flow through it. Dust inside the dust bin (220) of the robot vacuum cleaner (200) can move to the dust collection unit (140) through the first dust collection channel (147).

[0286] The second dust collection channel (148) can connect the dust collection unit (140) and the dust collection motor (145). The second dust collection channel (148) can be formed close to the horizontal direction. At this time, the first dust collection channel (147) and the second dust collection channel (148) can be formed at different heights. The first dust collection channel (147) and the second dust collection channel (148) can be formed in a stacked structure. The second dust collection channel (148) can be positioned lower than the first dust collection channel (147). With such a configuration, the width in the left-right direction and the overall volume of the robot vacuum cleaner station (100) can be minimized.

[0287] The dust collection module (150) can provide a suction airflow to the dust collection path (147, 148).

[0288] Specifically, the dust collection module (150) may include a dust collection motor housing (146) and a dust collection motor (145).

[0289] The dust collection motor housing (146) can be placed inside the housing (110). The dust collection motor housing (146) can accommodate a dust collection motor (145) inside.

[0290] The internal space of the dust collection motor housing (146) can be connected to the second dust collection path (148). Thus, air flowing through the second dust collection path (148) can be guided to the dust collection motor (145).

[0291] The internal space of the dust collection motor housing (146) can be connected to a circulation path. Thus, air passing through the dust collection motor (145) can be guided to the circulation path.

[0292] The dust collection motor (145) can generate suction force in the dust collection path (147, 148).

[0293] The dust collection motor (145) can be positioned at the rear of the dust collection unit (140). 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).

[0294] The dust collection motor (145) can generate suction force by rotation. For example, the dust collection motor (145) can be formed in a shape similar to a cylinder.

[0295] 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 circulation path. 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 pass through the dust collection motor (145), then flow through the circulation path and be exhausted to the air return port (125b).

[0296] Meanwhile, the rotation axis of the dust collection motor (145) can be formed close to the horizontal direction. With this configuration, the overall volume of the robot vacuum cleaner station (100) placed in the kitchen cabinet (2) or the mounting space (21a) of the structure can be minimized.

[0297] The exhaust section (125) can guide air discharged from the dust collection motor (145) to the outside of the housing (110). The exhaust section (125) can connect the internal space of the housing (110) with the external space.

[0298] The exhaust section (125) may be composed of a circulation path and an air return port (125b).

[0299] The circulation path can provide a path through which air discharged from the dust collection motor (145) flows. The circulation path can be placed inside the base body (121a).

[0300] The circulation path may be connected to the dust collection motor (145) via a path. The circulation path may refer to a path connecting the internal space of the motor housing (151) and the air return port (125b). One end of the circulation path may be in communication with the internal space of the dust collection motor housing (146), and the other end of the circulation path may be in communication with the receiving space of the recess (121da).

[0301] The circulation path may be a path formed along the horizontal direction inside the housing (110). The circulation path may be connected to the dust collection motor (145). Specifically, one end of the circulation path may be in communication with the dust collection unit (140), and the other end of the circulation path may be in communication with the air circulation port (125b).

[0302] The air return port (125b) can serve as an outlet to guide the air discharged from the dust collection motor (145) into the receiving space of the recess (121da). Thus, the air discharged from the dust collection motor (145) and flowing through the circulation path can be discharged to the outside of the housing (110) through the air return port (125b).

[0303] An air circulation port (125b) may be formed in the base (121). An air circulation port (125b) may be formed in the agitator receiving portion (121d). An air circulation port (125b) may be formed in the side wall of the recess (121da).

[0304] The circulation path according to an embodiment of the present invention can guide air discharged from a dust collection motor (145) to the suction part (211) of a robot vacuum cleaner (200).

[0305] The circulation path can be designed so that the air discharged from the dust collection motor (145) is guided to the suction part (211) of the robot vacuum cleaner (200) without being discharged 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).

[0306] 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 to the suction section (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 section (140), the second dust collection path (148), the dust collection motor (145), the circulation path, and the air return port (125b).

[0307] 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.

[0308] rag washing unit (160)

[0309] FIG. 15 shows an enlarged view illustrating a mop washing section of a robot vacuum cleaner station according to an embodiment of the present invention, FIG. 16 shows an enlarged view illustrating a washing water supply section of a mop washing section of a robot vacuum cleaner station according to an embodiment of the present invention, and FIG. 17 shows a drawing illustrating a state in which a dust collection section and a detergent container are withdrawn from a robot vacuum cleaner station according to an embodiment of the present invention.

[0310] Referring to FIGS. 15 to 17, the mop washing unit (160) of the robot vacuum cleaner station (100) according to an embodiment of the present invention is described as follows.

[0311] 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) can wash the mop (242) of a robot vacuum cleaner (200) coupled to a seating unit (120).

[0312] The mop washing unit (160) may include a washing water supply unit (161) that discharges washing water onto a washing plate (122), a detergent container (163) in which a liquid containing detergent is stored, and a wastewater container (164) in which washing water is stored after washing the mop (242) is finished.

[0313] In the washing water supply unit (161), purified water and detergent are mixed to produce washing water for washing the rag (242).

[0314] A pair of wash water supply units (161) may be spaced apart and positioned at the rear side of the connecting wall (123). The wash water supply units (161) may discharge wash water toward the wash plate (122) from the upper sides of both ends of the wash plate (122). At this time, purified water supplied from the water supply pipe of the kitchen cabinet (2) and passed through the regulator (162) may be branched to both sides through the branching path (161a) and connected to each of the spaced wash water supply units (161). That is, the branching path (161a) may be formed in the form of a single pipe branching into two, and at this time, one end of the branch may be connected to one of the pair of wash water supply units (161), and the other end of the branch may be connected to the other of the pair of wash water supply units (161).

[0315] The washing water supply unit (161) may be formed integrally with the connecting wall (123) at the rear side of the connecting wall (123) or may be detachably connected to the connecting wall (123).

[0316] A water supply unit (161) may have a purified water inlet (161b), a detergent inlet (161c), and a water discharge port (not shown).

[0317] The purified water inlet (161b) is configured to guide purified water supplied from the water supply pipe of the kitchen cabinet (2) to the washing water supply unit (161). Specifically, the water supply pipe of the kitchen cabinet (2) is connected to a regulator (162) so that the flow rate supplied from the water supply pipe can be regulated. Additionally, a portion of the purified water passing through the regulator (162) is supplied to the water tank (230) of the robot vacuum cleaner (200) through the water supply nozzle (123c), and the remainder can be introduced through the purified water inlet (161b) to a pair of washing water supply units (161) spaced apart from each other.

[0318] The detergent inlet (161c) is configured to guide the liquid containing detergent supplied from the detergent container (163) to the washing water supply unit (161). Specifically, the liquid containing detergent stored in the detergent container (163) can be supplied to the washing water supply unit (161) via a pump (not shown).

[0319] Additionally, the detergent and purified water introduced into the washing water supply unit (161) can be mixed and utilized as washing water. The washing water supply unit (161) can discharge the washing water to the upper surface of the washing plate (122) through the washing water discharge port. The washing water discharge port may be formed on the lower surface of the washing water supply unit (161). The washing water discharge port may be opened in a direction facing the upper surface of the rag (242) placed on the washing plate (122).

[0320] The detergent container (163) can store a liquid containing detergent.

[0321] This detergent container (163) can be placed between one of the left and right sides of the housing (110) and the seating portion (120). Specifically, the detergent container (163) can be placed between the right side (111d) of the housing (110) and the seating portion (120).

[0322] At this time, the distance in the left-right direction from the right side (111d) of the housing (110) to the seating portion (120) can be formed to be closer than the distance in the left-right direction from the left side (111c) of the housing (110) to the seating portion (120). Also, the width in the left-right direction of the detergent container (163) can be formed to be narrower than the width in the left-right direction of the dust bag drawer (144). Accordingly, the seating portion (120) can be positioned so that the center in the left-right direction is offset to the right from the center in the left-right direction of the housing (110).

[0323] The detergent container (163) includes a detergent container body (163a), a handle (163b), and a detergent container rail (163c) (see FIG. 17).

[0324] 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, and the rear can be connected to a washing water supply unit (161).

[0325] A handle (163b) may be provided at the front end 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 include a pair of connecting parts hinged to the front surface of the detergent container body (163a) and a gripping part formed by connecting the pair of connecting parts so that a user can grip it.

[0326] With this configuration, when a user grasps the gripper 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.

[0327] A detergent container rail (163c) may be formed on the left and right sides of the detergent container body (163a). The detergent container rail (163c) can guide the movement of the detergent container body (163a).

[0328] 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).

[0329] 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.

[0330] 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).

[0331] The wastewater tank (164) 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 drain hole (122b) while descending along the slope of the washing plate (122). The washing water passing through the drain hole (122b) accumulates in the washing tank (128). Additionally, the washing water accumulated in the washing tank (128) can flow into the wastewater tank (164) through the wastewater suction path (164b).

[0332] The washing water stored in the wastewater tank (164) can be drained into the drain pipe (25) of the kitchen cabinet (2) through the wastewater discharge path (164a). One end of the wastewater discharge path (164a) can be connected to the wastewater tank (164), and the other end can be connected to the drain pipe (25). At this time, the washing water stored in the wastewater tank (164) can be drained into the drain pipe by flowing through the wastewater discharge path (164a) by a centrifugal pump (not shown).

[0333] The wastewater discharge path (164a) connected to the wastewater tank (164) 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 (164a) 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 (164a).

[0334] 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 (164a). The check valve may be provided at the other end of the wastewater discharge path (164a) connected to the drain pipe (25).

[0335] Meanwhile, the detergent container (163) and the wastewater container (164) 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 (164) can be placed on the upper side of the detergent container (163) in the space between the inner wall (124) and the outer wall (111) of the housing.

[0336] rag drying section (170)

[0337] FIG. 18 shows a perspective view illustrating a mop drying section of a robot vacuum cleaner station according to an embodiment of the present invention, FIG. 19 shows an enlarged view of a mop drying section of a robot vacuum cleaner station according to an embodiment of the present invention, and FIG. 20 shows a cross-sectional view illustrating the flow of air into an external air supply module according to an embodiment of the present invention.

[0338] Referring to FIGS. 18 to 20, 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.

[0339] A mop drying unit (170) according to one embodiment of the present invention may include an external air supply module (171), an air discharge unit (172), an exhaust fan (173), and a check valve (not shown).

[0340] The outside air supply module (171) can supply heat to the receiving space (S) and may include an outside air supply path (171a), a blower fan (not shown), and a heater (171d).

[0341] The external air supply channel (171a) can connect the external space of the housing (110) with the receiving space (S). 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 port (171c).

[0342] An external air inlet (171b) can be formed on the rear surface of the housing (110).

[0343] The outside air outlet (171c) may be positioned on the upper side of the cleaning plate (122). The outside air outlet (171c) may be opened in a direction facing the cleaning plate (122). A pair of outside air outlets (171c) may be provided in a state where they are open downwards.

[0344] With the mop (242) seated on the cleaning plate (122), the outside air outlet (171c) can be opened toward the upper side of the mop (242). That is, the outside air outlet (171c) can be opened in a direction facing the mop (242). Thus, the outside air outlet (171c) is positioned adjacent to the mop (242) and is opened downward, so that air discharged from the outside air outlet (171c) can flow toward the mop (242).

[0345] 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 outlet (171c).

[0346] 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 outlet (171c).

[0347] The heater (171d) may include a heater housing (171da) and a heating element (not shown). 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 the 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 port (171c) to dry the wet rag (242).

[0348] The air exhaust unit (172) can discharge the hot and humid air inside the robot vacuum cleaner station (100) generated while drying the mop (242) into the drain pipe (25). Specifically, the air exhaust unit (172) can connect the receiving space (S) and the drain pipe (25) of the kitchen cabinet (2).

[0349] One end of the air discharge section (172) can be connected to a receiving space (S), and the other end can be connected to a drain pipe (25). Specifically, the air intake port (172a), which is one end of the air discharge section (172), can be connected to a receiving space (S), and the air discharge port (172b), which is the other end, can be connected to a drain pipe (25).

[0350] Meanwhile, the air intake (172a) can be positioned at various locations on the receiving space (S). For example, the air intake (172a) can be positioned on the connecting wall (123). For another example, the air intake (172a) can be positioned higher than the ground than the mop (242) but positioned in front of the outside air discharge port (171c). Through this, steam generated during the drying process of the mop (242) can be discharged.

[0351] The air exhaust section (172) can be connected downstream (25c) relative to the U-trap (25a) of the drain pipe (25) of the kitchen cabinet (2). This is because if the air exhaust section (172) is connected upstream (25b) relative to the U-trap (25a) of the drain pipe (25), the heat exhausted through the air exhaust section (172) may not be able to pass through the drain pipe (25) due to the water accumulated in the U-trap (25a).

[0352] Meanwhile, the air discharge section (172) can be formed by a single pipe branching into two within the housing (110) and penetrating both sides of the housing (110). At this time, one of the branches penetrates the left outer wall of the housing (110), and the other branch penetrates the right outer wall of the housing (110). The air discharge section (172) penetrating both outer walls (111) of the housing (110) can be connected to the drain pipe (25). Accordingly, steam from the receiving space (S) sucked in by the air discharge section (172) can flow through the air discharge section (172) branched to both sides and be exhausted downstream (25c) relative to the U-trap (25a) of the drain pipe (25).

[0353] The exhaust fan (173) can exhaust air from the receiving space (S) into the drain pipe (25) through the air discharge section (172). The exhaust fan (173) can cause airflow in the air introduced into the air discharge section (172). The exhaust fan (173) can be placed on the air discharge section (172).

[0354] When the exhaust fan (173) 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 flow through the air discharge section (172) and be exhausted into the drain pipe (25). Specifically, the air flowing through the air discharge section (172) when the exhaust fan (173) is driven can be exhausted downstream (25c) relative to the U-trap (25a) of the drain pipe (25).

[0355] The rag drying section (170) may include a check valve (not shown). The check valve may be provided at the other end of the air discharge section (172) connected to the drain pipe (25). This prevents the fluid inside the drain pipe (25) from flowing back into the air discharge section (172).

[0356] Layout

[0357] FIGS. 21 and 22 illustrate a diagram illustrating the arrangement relationship of a robot vacuum cleaner station on a horizontal plane according to an embodiment of the present invention.

[0358] With reference to FIGS. 4, FIGS. 21 and FIGS. 22, the arrangement of a robot vacuum cleaner station (100) according to an embodiment of the present invention is described as follows.

[0359] 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).

[0360] 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.

[0361] 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).

[0362] 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).

[0363] For example, an entrance (127) and a door (126) 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.

[0364] 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).

[0365] At this time, the dust bag (not shown) of the dust collection unit (140) is detachably connected to the housing (110) and can move forward when separated from the housing (110). Additionally, the detergent container (163) of the mop washing unit (160) is detachably connected to the housing (110) and can move forward when separated from the housing (110).

[0366] Specifically, the dust bag (not shown) of the dust collection unit (140) may be arranged along the front-rear direction inside the housing (110) and may be provided so as to be pulled out toward the front of the housing (110). Additionally, the detergent container (163) of the mop washing unit (160) may be arranged along the front-rear direction inside the housing (110) and may be provided so as to be pulled out toward the front of the housing (110).

[0367] That is, a handle (144d) may be provided at the front end of the dust collection unit (140) so that a user can grasp the dust collection unit housing (141). Additionally, a handle (163b) may be provided at the front end of the mop washing unit (160) so that a detergent container (163) can be pulled.

[0368] With this configuration, when a user wants to retrieve a dust bag (not shown) or a detergent container (163), the user can immediately recognize the location of the retrieval and can retrieve the dust bag (not shown) or the detergent container (163) with just a simple motion of pulling the handle, thereby providing convenience.

[0369] Meanwhile, the rear ends of the dust collection unit (140) and the mop washing unit (160) 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 housing (110) and the rear end of the dust collection unit (140). With this configuration, it is easy to connect the wires supplying power to the dust collection motor (145). Furthermore, there is an effect of minimizing the total space occupied by the mounting unit (120), the dust collection unit (140), and the dust collection motor (145) within a limited space.

[0370] Additionally, between the rear end of the housing (110) and the rear end of the mop washing section (160), at least a flow path through which washing water for washing the mop (242) can flow and a pump providing the flow force of the washing water may be partially arranged. 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 section (120), the mop washing section (160), and the flow path through which washing water flows can be minimized.

[0371] Additionally, a detergent path (not shown) connecting the detergent to the washing water supply unit (161) may be arranged between the rear end of the housing (110) and the rear end of the detergent container (163). When the detergent container (163) is withdrawn from the housing (110), the rear end is separated from the detergent path, and when the detergent container (163) is inserted into the housing (110), the rear end can be connected to the detergent path.

[0372] 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).

[0373] 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.

[0374] 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).

[0375] Through this arrangement, the seating section (120), dust collection section (140), mop washing section (160), and mop drying section (170) can all be arranged in the narrowest space on the horizontal plane.

[0376] 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.

[0377] In addition, by this arrangement, the robot vacuum cleaner station (100) of the present invention can arrange all components within a limited height.

[0378] Specifically, based on the state in which the robot vacuum cleaner (200) is coupled to the mounting portion (120), at least a portion of the dust collection portion (140) may be positioned lower than the top of the robot vacuum cleaner (200). Additionally, at least a portion of the mop washing portion (160) may be positioned lower than the top of the robot vacuum cleaner (200). Additionally, at least a portion of the mop drying portion (170) may be positioned lower than the top of the robot vacuum cleaner (200). Additionally, at least a portion of the mop washing portion (160) may be positioned lower than the top of the dust collection portion (140).

[0379] Additionally, based on the state in which the robot vacuum cleaner (200) is coupled to the mounting portion (120), the top of the robot vacuum cleaner (200) may be positioned higher than the dust bag (not shown). Additionally, the top of the robot vacuum cleaner (200) may be positioned higher than the detergent container (163). Additionally, the top of the dust bag (not shown) may be positioned higher than the detergent container (163).

[0380] 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).

[0381] Drawer (190)

[0382] 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).

[0383] In this regard, FIG. 23 illustrates a state in which a drawer is provided in a robot vacuum cleaner station according to an embodiment of the present invention, and FIG. 24 illustrates a state in which a drawer is withdrawn in a robot vacuum cleaner station according to an embodiment of the present invention.

[0384] Referring to FIGS. 23 and 24, a drawer (190) of a robot vacuum cleaner station (100) according to one embodiment of the present invention is described as follows.

[0385] A robot vacuum cleaner station (100) according to one embodiment of the present invention may further include a drawer (190) that is withdrawn from a housing (110).

[0386] When the drawer (190) is inserted into the housing (110), the door (126) can be closed when the robot vacuum cleaner (200) enters the seating portion (120). In this case, the inside and outside of the housing (110) can be blocked by the door (126) for the robot vacuum cleaner (200).

[0387] As a result, the robot vacuum cleaner (200) can prevent dust from scattering outside the robot vacuum station (100) while dust collection is performed on the dust bin (220) inside the housing (110). Additionally, it can prevent wastewater from leaking outside the robot vacuum station (100) while cleaning of the mop (242) is performed.

[0388] 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).

[0389] 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).

[0390] At this time, when the drawer (190) is withdrawn from the housing (110) while the door (126) is closing the entrance (127), the robot vacuum cleaner (200) placed in the seating portion (120) can be exposed to the outside.

[0391] 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).

[0392] Meanwhile, a drawer (190) according to one embodiment of the present invention can be withdrawn with a dust collection unit (140) provided inside. That is, the drawer (190) can be withdrawn together with the dust collection unit (140).

[0393] On the other hand, the dust collection unit (140) of the present invention can be withdrawn from the housing (110) separately from the drawer (190). At this time, the withdrawal direction of the dust collection unit (140) may be parallel to the direction in which the drawer (190) is withdrawn. For example, the withdrawal direction of the dust bag drawer (144) may be parallel to the withdrawal direction of the drawer (190).

[0394] Additionally, a drawer (190) according to one embodiment of the present invention may be withdrawn with at least a portion of a mop washing unit (160) provided inside. That is, the drawer (190) may be withdrawn together with at least a portion of the mop washing unit (160). For example, the drawer (190) may be withdrawn together with a detergent container (163) and a wastewater container (164).

[0395] On the other hand, the detergent container (163) of the present invention can be withdrawn from the housing (110) separately from the drawer (190). At this time, the withdrawal direction of the detergent container (163) may be parallel to the direction in which the drawer (190) is withdrawn.

[0396] 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 collection unit (140), and detergent container (163) all having parallel drawing directions.

[0397] 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.

[0398] The drawer (190) includes a drawer side wall (191), a fitting part (192), and a drawer rail (193).

[0399] The drawer side wall (191) is provided to be movable relative to the outer wall 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).

[0400] 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).

[0401] At this time, a pair of drawer side walls (191) can be directly connected to the base (121) of the seating portion (120). Alternatively, a pair of drawer side walls (191) can be connected by a drawer base (not shown), and it is also possible for the seating portion (120) to be coupled to the upper side of the drawer base (not shown) and to move together.

[0402] 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). That is, based on the state in which the robot vacuum cleaner (200) is coupled to the seating unit (120), a dust collection unit (140) and / or a mop washing unit (160) may be disposed between the robot vacuum cleaner (200) and the drawer side wall (191).

Alternatively, although not shown, the door (1126) may be positioned to slope downward or upward as it moves forward when the doorway (127) is opened.

[0455] Meanwhile, the door (1126) may be operated to open or close depending on whether the robot vacuum cleaner (200) approaches or starts driving, or may be operated to open or close depending on the input of the door control unit (133).

[0456] The housing (110) may be equipped with a sensor (not shown) to detect the approach of the robot vacuum cleaner (200). The sensor may be positioned at the front of the housing (110) or on one side of the door (1126) to detect the approach of the robot vacuum cleaner (200).

[0457] The housing (110) may be provided with a sensor mounting portion (not shown) formed such that a portion of the front surface protrudes forward. The sensor mounting portion may be positioned in the center of the left and right directions of the housing (110) and may be positioned at the bottom of the housing (110).

[0458] Here, the robot vacuum cleaner station (100) is configured so that the sensor (101) can detect the front even when the door (1126) closes the entrance (115b). The door (1126) may be configured to cover the entire front end of the housing (110), excluding the sensor, when the entrance (115b) closes.

[0459] The housing (110) is equipped with a door control unit (not shown) to allow the door (1126) to be rotated arbitrarily. The door control unit is positioned in the housing (110) and may include at least one button (not shown) for operating the door (1126). The door control unit is provided to rotate the door (1126) without considering the position or state of the robot vacuum cleaner (200).

[0460] The door (1126) can be rotated by a door drive unit (130). For example, the door drive unit (130) may include a door drive motor (131) and a drive gear unit (132).

For example, the drive gear unit (132) may include a drive gear (132db) and a driven gear (132f). The drive gear (132db) is connected to the motor shaft of the door drive motor (131) to receive rotational force and meshes with the driven gear (132f) to transmit rotational force to the driven gear (132f). The driven gear (132f) meshes with the drive gear (132db) and may be arranged coaxially with the door hinge unit (1126a) of the door (1126). The driven gear (132f) can be integrally provided with the door (1126) and can rotate together with the door (1126) around the rotation axis of the door hinge part (1126a) when the door driving motor (131) is driven.

[0463] Referring to FIGS. 29 to 32, the door (2126, 3126) is deformed in shape to reduce the volume protruding forward when opened, thereby minimizing inconvenience to the user's movement.

[0464] Since the vacuum cleaner system (1) of the present invention is installed using the lower space of the kitchen cabinet (2), it must be positioned so as not to protrude forward beyond the kitchen cabinet (2). Also, the door (2126, 3126) covering the front part of the robot vacuum cleaner station (100) can also be positioned so as not to protrude forward beyond the kitchen cabinet (2) when closed. In addition, even when the door (2126, 3126) is in an open state, the shape of the door (2126, 3126) can be deformed as the door (2126, 3126) is opened in order to minimize the volume of the door (2126, 3126) being discharged forward beyond the kitchen cabinet (2).

[0465] The door (2126, 3126) is provided in the form of a plate to cover the entire front portion of the housing (110) when the door (115b) is closed, and its shape may be deformed when the door (115b) is opened. As the door (2126, 3126) is deformed when the door (115b) is opened, the length of the door (2126, 3126) protruding forward from the housing (110) when open may be shorter than the vertical length when the door (2126, 3126) is closed.

[0466] When the door (2126, 3126) is opened, the door (2126, 3126) is positioned above the entrance (115b), one side of the detergent container (163) and one side of the dust bag drawer (144) are exposed, and the entrance (115b) is opened. The height from the ground to the door (2126, 3126) may be higher than the height from the ground to the very top of the entrance (115b). Additionally, when the door (2126, 3126) is opened, the door (2126, 3126) may be positioned above the detergent container (163) and above the dust bag drawer (144). And, when the door (2126, 3126) is opened, a door drive motor (131) may be placed between the door (2126, 3126) and the detergent container (163).

[0467] Referring to FIGS. 29 to 30 to specifically describe these doors (2126, 3126), the door (2126) may be provided in a rotatable form and may be folded at least once when rotated to minimize the volume protruding from the kitchen cabinet (2).

[0468] In this way, the door (2126) is provided in a rotating form and folds while opening the doorway (115b), thereby preventing interference or collision with the kitchen cabinet (2) when the door (2126) is opened and minimizing user inconvenience.

[0469] The door hinge portion (2126a) of such a door (2126) may be rotatably installed on the top of the housing (110). As shown in the drawing, the door (2126) may be folded in half with the door hinge portion (2126a) installed on the top of the housing (110). Alternatively, although not shown in the drawing, the door (2126) may be folded twice or three times when opened.

[0470] Specifically, the door (2126) may include a first folding door (2126b) and a second folding door (2126c). The first folding door (2126b) and the second folding door (2126c) may be provided in the form of plates, and may be provided such that their length in the left-right direction is equal to or greater than the length in the left-right direction of the housing (110). The first folding door (2126b) and the second folding door (2126c) may be provided such that their width-direction length is half that of the door (2126).

[0471] The first folding door (2126b) and the second folding door (2126c) may be linked or integrally connected, and a folding section (2126d) may be provided between the first folding door (2126b) and the second folding door (2126c). The folding section (2126d) may be unfolded so that the first folding door (2126b) and the second folding door (2126c) are located on the same plane when the door (2126) is opened, and may be bent so that the first folding door (2126b) and the second folding door (2126c) overlap when the door (2126) is closed. Additionally, the folding section (2126d) may be provided in the form of a pin that links the first folding door (2126b) and the second folding door (2126c), and the second folding door (2126c) may be arranged to extend from the first folding door (2126b) by rotating around the center of the folding section (2126d), or arranged to overlap with the first folding door (2126b). The folding section (2126d) may be positioned in the center of the door (2126) in the vertical direction.

[0472] One end of the first folding door (2126b) in the width direction is rotatably installed on the top of the housing (110), and the other end in the width direction is connected to the second folding door (2126c) through the folding part (2126d). The first folding door (2126b) can be rotated so that when the door (2126) is opened, the other end is positioned above the entrance (115b).

[0473] The second folding door (2126c) is rotatably installed on the first folding door (2126b) and can be positioned to overlap with the first folding door (2126b) when the door (2126) is opened. One end of the second folding door (2126c) in the width direction is connected to the first folding door (2126b) through a folding section (2126d), and a door support section (2126e) may be provided at the other end in the width direction. At least one door support section (2126e) is provided to support one end of the first folding door (2126b) when the door (2126) is opened. The door support section (2126e) is formed by protruding at least a portion of the other end in the width direction of the second folding door (2126c) and may be arranged along the length direction of the second folding door (2126c). The door support (2126e) may be provided protruding from the inner side of the second folding door (2126c). The second folding door (2126c) may be rotated so that when the door (2126) is opened, one end and the other end are positioned above the entrance (115b). However, the first folding door (2126b) and the second folding door (2126c) may be rotated so that when the door (2126) is opened, they are positioned at the same height as the upper side of the housing (110) or at a lower height than the upper side of the housing (110) to prevent interference with the kitchen cabinet (2). That is, when the door (2126) is opened, the height from the ground to both ends of the first folding door (2126b) and the second folding door (2126c) may be positioned at the same height as or lower than the height from the ground to the upper side of the housing (110).

[0474] When the door (2126) is opened, the first folding door (2126b) and the second folding door (2126c) may be positioned parallel to the ground. Alternatively, when the door (2126) is opened, as the door support member (2126e) supports the first folding door (2126b), at least one of the first folding door (2126b) and the second folding door (2126c) may be positioned at an angle to the ground. With this configuration, the first folding door (2126b) and the second folding door (2126c) can be easily unfolded from a folded state, and impact and noise caused by collision between the first folding door (2126b) and the second folding door (2126c) can be minimized.

[0475] The door (2126) can be driven by the door drive unit (130) to open and close the doorway (115b).
