Description

Drying module for mop nozzle

[0001] The present invention relates to a drying module for a mop nozzle, and more particularly, to a drying module for a mop nozzle that is coupled to a vacuum cleaner station and can dry the mop module of the vacuum cleaner.

[0002]

[0003] In general, a vacuum cleaner is a home appliance that uses electricity to suck up air and fills a dust bin inside the product with small pieces of trash or dust. It is commonly called a vacuum cleaner.

[0004] These vacuum cleaners can be categorized into manual vacuum cleaners, which the user moves to clean, and automatic vacuum cleaners, which clean by moving around on their own. Manual vacuum cleaners can be categorized by type, including canister vacuum cleaners, upright vacuum cleaners, handheld vacuum cleaners, and stick vacuum cleaners.

[0005] In the past, canister-type vacuum cleaners were widely used in household vacuum cleaners, but recently, handheld vacuum cleaners and stick vacuum cleaners that provide the dust bin and vacuum cleaner body as an integrated unit, which improves convenience, are being widely used.

[0006] The canister-type vacuum cleaner has a main body and suction inlet connected by a rubber hose or pipe, and in some cases, a brush can be inserted into the suction inlet for use.

[0007] Handheld vacuum cleaners maximize portability. They are lightweight, but their short length limits the cleaning area they can be used in while seated. Therefore, they are used for cleaning small areas, such as desks, sofas, or inside cars.

[0008] Stick vacuums can be used standing up, allowing for cleaning without bending down. This makes them ideal for moving around and cleaning large areas. While handheld vacuums are suitable for cleaning tight spaces, stick vacuums can clean wider areas and reach high, out-of-reach places. Recently, stick vacuums have been offered in modular configurations, allowing users to actively adapt the vacuum to suit a variety of applications.

[0009] However, conventional handheld vacuum cleaners and stick vacuum cleaners had a small dustbin capacity for storing collected dust, which was inconvenient for users to have to empty the dustbin every time.

[0010] Additionally, there was a problem that when the dustbin was emptied, dust would fly around, which had a harmful effect on the user's health.

[0011] Additionally, there was a problem that the suction power of the vacuum cleaner was reduced if the remaining dust in the dustbin was not removed.

[0012] Additionally, there was a problem of bad odor caused by residue if the remaining dust in the dustbin was not removed.

[0013] Korean Patent Publication No. 10-2022-0041327 discloses a vacuum cleaner station that can automatically empty the vacuum cleaner's dust bin when the vacuum cleaner is attached.

[0014] In the above prior art patent document, when a vacuum cleaner is connected to a vacuum cleaner station, a dust collection motor is operated to empty the vacuum cleaner's dust bin.

[0015] Additionally, in the case of the above cleaner station, various nozzles can be mounted on the housing.

[0016] In particular, in the case of the above-mentioned cleaning station, a hanging device for hanging a mop is provided on the side of the cleaning station.

[0017] However, in the case of the above cleaner station, although dust collection is possible for the dust bin of the cleaner body, a structure capable of managing the nozzle of the cleaner is not disclosed.

[0018] In particular, in the case of a mop nozzle that sprays water or steam onto a mop to clean the floor, there is no separate device to manage the wet mop, so if the mop is placed on the outside of the side of the cleaning station while wet, there is a limitation that water may fall onto the floor, causing contamination or a bad smell.

[0019]

[0020] The present invention was created to improve the problems of the conventional vacuum cleaner station as described above, and its purpose is to provide a drying module for a mop nozzle capable of managing the mop nozzle of a vacuum cleaner.

[0021] In addition, the purpose is to provide a drying module for a mop nozzle that can dry the mop and prevent bacterial growth, etc.

[0022] Additionally, the purpose is to provide a drying module for a mop nozzle that can improve space efficiency by utilizing the space around the vacuum cleaner station.

[0023]

[0024] In order to achieve the above-described purpose, a drying module for a mop nozzle according to the present invention may include a module housing detachably coupled to a vacuum cleaner station that collects dust of the vacuum cleaner; a heater disposed inside the module housing and heating air; and an outlet disposed at a position facing the vacuum cleaner mop and discharging air heated by the heater.

[0025] Accordingly, hot air can be blown toward the mop to dry the mop.

[0026] In addition, the drying module for a mop nozzle according to the present invention may further include a nozzle coupling part, which is disposed in the module housing and to which the mop nozzle of the cleaner is coupled.

[0027] Alternatively, the drying module for the mop nozzle according to the present invention may further include a drying rack detachably coupled to the module housing and accommodating at least a portion of the mop.

[0028] Accordingly, the mop can be separated and placed and dried separately.

[0029] Meanwhile, the module housing can be attached to a hanger provided on the side of the cleaner station.

[0030] In another embodiment of the present invention, a drying module for a mop nozzle comprises a module housing that can be retractably connected to the lower side of the station. This allows for the mop nozzle to be managed using only a narrow space.

[0031] A drying module for a mop nozzle according to another embodiment of the present invention may further include a battery coupling part disposed inside the module housing and to which a battery of the cleaner is coupled.

[0032] In addition, a drying module for a mop nozzle according to another embodiment of the present invention may further include a mop coupling part, which is disposed inside the module housing and to which the mop is coupled.

[0033] In addition, a drying module for a mop nozzle according to another embodiment of the present invention may further include an auxiliary battery coupling unit, which is disposed inside the module housing and to which an auxiliary battery detachably coupled to the mop nozzle of the vacuum cleaner is coupled.

[0034] In addition, a drying module for a mop nozzle according to another embodiment of the present invention may further include a handle disposed on the front surface of the module housing and capable of being gripped. This has the advantage of allowing the module housing to be withdrawn by a simple action of pulling the handle.

[0035] Meanwhile, a drying module for a mop nozzle according to another embodiment of the present invention may further include a support wall coupled to the lower side of the cleaner station to support the station and accommodating at least a portion of the module housing.

[0036]

[0037] As described above, the drying module for the mop nozzle according to the present invention has the effect of managing not only the main body of the vacuum cleaner but also the mop nozzle by combining the device for managing the mop nozzle with the vacuum cleaner station, thereby managing the mop nozzle as well.

[0038] Additionally, it can be dried quickly by blowing warm air through a mop, which has the effect of preventing bacterial growth and improving hygiene.

[0039] Additionally, the space on the side or bottom of the vacuum cleaner station can be used to store and dry the mop nozzle, which has the effect of improving space efficiency.

[0040] Additionally, it has the effect of allowing you to separate and dry only the mop when necessary.

[0059]

[0060] FIG. 1 is a perspective view of a cleaning system comprising a cleaning station and a drying module for a mop nozzle according to one embodiment of the present invention.

[0061] The vacuum cleaner system (10) may include a vacuum cleaner station (100). A vacuum cleaner (200) may be coupled to the vacuum cleaner station (100). Specifically, a main body of the vacuum cleaner (200) may be coupled to a side of the vacuum cleaner station (100). The vacuum cleaner station (100) may remove dust from a dust bin (220) of the vacuum cleaner (200).

[0062]

[0063] Referring to FIG. 1, the cleaning station (100) of the present invention is described as follows.

[0064] A cleaner (200) may be placed in the cleaner station (100). The cleaner (200) may be coupled to a side of the cleaner station (100). Specifically, the main body of the cleaner (200) may be coupled to the side of the cleaner station (100). The cleaner station (100) may remove dust from the dust bin (220) of the cleaner (200).

[0065] The cleaning station (100) may include a housing (110). The housing (110) may form the exterior of the cleaning station (100). Specifically, the housing (110) may be formed in a columnar shape including at least one outer wall surface. For example, the housing (110) may be formed in a shape similar to a square column.

[0066] The housing (110) may be formed with a space that can accommodate a dust collection unit that stores dust inside and a dust suction module that generates a fluid force that collects dust.

[0067] The housing (110) may include a bottom surface (111), an outer wall surface (112), and an upper surface (113).

[0068] The bottom surface (111) can support the lower side of the dust suction module in the direction of gravity. That is, the bottom surface (111) can support the lower side of the dust collection motor of the dust suction module.

[0069] At this time, the bottom surface (111) can be positioned facing the ground. The bottom surface (111) can be positioned parallel to the ground, but can also be positioned at a predetermined angle with the ground. This configuration can stably support the dust collection motor, and has the advantage of balancing the overall weight even when the vacuum cleaner (200) is combined.

[0070] Meanwhile, according to an embodiment, the bottom surface (111) may further include a ground support member that increases the area in contact with the ground to prevent the cleaner station (100) from falling over and maintain balance. For example, the ground support member may be in the form of a plate extending from the bottom surface (111), and one or more frames may be formed to protrude and extend along the ground direction from the bottom surface (111).

[0071] The outer wall surface (112) may refer to a surface formed along the direction of gravity. For example, the outer wall surface (112) may refer to a surface vertically connected to the floor surface (111). In another embodiment, the outer wall surface (112) may be arranged to be inclined at a predetermined angle with respect to the floor surface (111).

[0072] The outer wall surface (112) may be configured to include at least one surface. For example, the outer wall surface (112) may include a first outer wall surface (112a), a second outer wall surface (112b), a third outer wall surface (112c), and a fourth outer wall surface (not shown).

[0073] At this time, in the present embodiment, the first outer wall surface (112a) may be placed on the front side of the cleaner station (100). Here, the front side may refer to the surface where the cleaner (200) is exposed when the cleaner (200) is coupled to the cleaner station (100). Therefore, the first outer wall surface (112a) may form the appearance of the front side of the cleaner station (100).

[0074] Meanwhile, for the purpose of understanding this embodiment, the direction is defined as follows. In this embodiment, the direction can be defined while the cleaner (200) is mounted on the cleaner station (100).

[0075] When the cleaner (200) is mounted on the cleaner station (100), the direction in which the cleaner (200) is exposed to the outside of the cleaner station (100) can be called the front.

[0076] From another perspective, when the cleaner (200) is mounted on the cleaner station (100), the direction in which the suction motor (not shown) of the cleaner (200) is positioned can be called the front. And the direction opposite to the direction in which the suction motor (not shown) is positioned in the cleaner station (100) can be called the rear.

[0077] And, based on the internal space of the housing (110), the surface facing the front can be called the rear of the cleaner station (100). Accordingly, the rear can mean the direction in which the second outer wall surface (112b) is formed.

[0078] And, when looking at the front surface based on the internal space of the housing (110), the left side may be called the left side, and the right side may be called the right side. Accordingly, the left side may refer to the direction in which the third outer wall surface (112c) is formed, and the right side may refer to the direction in which the fourth outer wall surface (not shown) is formed.

[0079] The first outer wall surface (112a) may be formed in a flat shape, or may be formed in a curved shape overall, or may be formed to include a curved surface in a portion.

[0080] The first outer wall surface (112a) may have an exterior shape corresponding to the shape of the cleaner (200). Specifically, a coupling portion (120) may be arranged on the first outer wall surface (112a). With this configuration, the cleaner (200) may be coupled to the cleaner station (100) and supported by the cleaner station (100). The specific configuration of the coupling portion (120) will be described later.

[0081] In this embodiment, the second outer wall surface (112b) may be a surface facing the first outer wall surface (112a). That is, the second outer wall surface (112b) may be placed at the rear of the cleaner station (100).

[0082] In this embodiment, the third outer wall surface (112c) and the fourth outer wall surface (not shown) may refer to surfaces connecting the first outer wall surface (112a) and the second outer wall surface (112b). At this time, the third outer wall surface (112c) may be arranged on the left side of the station (100), and the fourth outer wall surface (not shown) may be arranged on the right side of the cleaner station (100). Alternatively, the third outer wall surface (112c) may be arranged on the right side of the cleaner station (100), and the fourth outer wall surface (not shown) may be arranged on the left side of the cleaner station (100).

[0083] The third outer wall surface (112c) or the fourth outer wall surface (not shown) may be formed in a flat shape, or may be formed in a curved shape overall, or may be formed by including a curved surface in a portion thereof.

[0084] Meanwhile, a hanging part (114) for holding various types of cleaning modules (260) used in a vacuum cleaner (200) may be added to the third outer wall surface (112c) or the fourth outer wall surface (not shown).

[0085] In particular, in a cleaner station (100) according to one embodiment of the present invention, a hanging part (114) is provided on the third outer wall surface (112c) or the fourth outer wall surface (not shown) so that a drying module (300) for a mop nozzle can be mounted.

[0086] The upper surface (113) may form the upper exterior of the cleaner station. That is, the upper surface (113) may mean a surface that is positioned at the uppermost side in the direction of gravity in the cleaner station and is exposed to the outside.

[0087] For reference, in this embodiment, the upper and lower sides may mean the upper and lower sides, respectively, along the direction of gravity (the direction perpendicular to the ground) when the cleaner station (100) is installed on the ground.

[0088] At this time, the upper surface (113) may be arranged parallel to the ground, or may be arranged at a certain angle with the ground.

[0089] A display unit (not shown) may be placed on the upper surface (113). For example, the display unit may display the status of the cleaner station (100) and the status of the cleaner (200), and may also display information such as the cleaning progress status and a map of the cleaning area.

[0090] Meanwhile, depending on the embodiment, the upper surface (113) may be provided to be detachable from the outer wall surface (112). In this case, when the upper surface (113) is detached, the internal space surrounded by the outer wall surface (112) may accommodate a battery detached from the vacuum cleaner (200), and a terminal (not shown) for charging the detached battery may be provided.

[0091]

[0092] The vacuum cleaner station (100) may include a coupling part (120) to which the vacuum cleaner (200) is coupled. Specifically, the coupling part (120) is arranged on the first outer wall surface (112a), and the main body (210), dust bin (220), and battery housing (230) of the vacuum cleaner (200) may be coupled.

[0093] The joint (120) may refer to a surface formed in a concave groove shape toward the inside of the cleaner station (100) on the first outer wall surface (112a) and a side wall surrounding the surface.

[0094] Accordingly, the coupling portion (120) can accommodate a vacuum cleaner (200). For example, the coupling portion (120) can accommodate at least a portion of a dustbin (220) of the vacuum cleaner (200) and at least a portion of a battery housing (230). Here, the lower side may refer to a side facing the ground when a user uses the vacuum cleaner (200) or places it on the ground.

[0095] For example, the angle formed by the coupling surface (121) with the ground may be a right angle. This allows the space of the cleaning station (100) to be minimized when the cleaner (200) is coupled to the coupling surface (121).

[0096] As another example, the coupling surface (121) may be arranged to be inclined at a predetermined angle with respect to the ground. Through this, when the cleaner (200) is coupled to the coupling surface (121), the cleaner station (100) can be stably supported.

[0097] A dust passage hole (not shown) may be formed in the coupling portion (120) to allow air from outside the housing (110) to flow into the inside. The dust passage hole (not shown) may be formed in the shape of a hole corresponding to the shape of the dust bin (220) to allow dust from the dust bin (220) to flow into the dust collection unit. The dust passage hole (not shown) may be formed corresponding to the shape of an exhaust cover that opens and closes the internal space of the dust bin (220). The dust passage hole (not shown) may be formed to communicate with a flow path portion (not shown) to be described later.

[0098] The lower part of the coupling part (120) may be formed in a shape corresponding to the outer surface of the dust bin (220). The front outer surface of the dust bin (220) may be coupled to the lower part of the coupling part (120).

[0099] Meanwhile, a cover opening hole (not shown) may be formed in the coupling portion (120), and a cover opening member (not shown) to be described later may pass through the cover opening hole (not shown) to press a coupling lever (not shown) that opens the discharge cover (not shown).

[0100] A coupling sensor (not shown) may be placed in the coupling portion (120). The coupling sensor (not shown) can detect whether the cleaner (200) is coupled to the coupling portion (120).

[0101] The coupling sensor (not shown) may include a contact sensor. For example, the coupling sensor (not shown) may include a micro switch.

[0102] Meanwhile, the combined sensor (not shown) may also include a non-contact sensor. For example, the combined sensor (not shown) may include an infrared sensor (IR sensor).

[0103] The coupling sensor (not shown) may face the dust bin (220) or battery housing (230) of the vacuum cleaner (200).

[0104] The coupling sensor (not shown) can be a means for determining whether the vacuum cleaner (200) is coupled, along with power being supplied to the battery (240) of the vacuum cleaner (200).

[0105] The joint (120) may further include a fixed member entry / exit hole (not shown). The fixed member entry / exit hole (not shown) may be formed in the shape of a long hole along the side wall (124) to allow the fixed member (131) to enter / exit.

[0106] With this configuration, when a user couples the vacuum cleaner (200) to the vacuum cleaner station (100), the convenience of having the dust bin (220) and battery housing (230) of the vacuum cleaner (200) coupled to the coupling portion (120) can be provided.

[0107] Although not shown, the cleaner station (100) of the present invention may include a fixed unit (not shown). The fixed unit (not shown) may be placed on the coupling portion (120). The fixed unit (not shown) may fix the cleaner (200) coupled to the coupling portion (120).

[0108] A fixed unit (not shown) can pressurize and fix the dust bin (220) of the cleaner (200) when the cleaner (200) is coupled to the cleaner station (100). To this end, the fixed unit can include a fixed member that moves from the outside of the dust bin (220) toward the dust bin (220) when the dust bin (220) is coupled to the coupling portion (120), a motor for driving the fixed member, and a power transmission member (e.g., a link) for transmitting power to the motor.

[0109] Although not shown, the vacuum cleaner station (100) of the present invention may include a dust bin cover control unit. The dust bin cover control unit may be configured to open and close a dust passage hole (not shown).

[0110] The dustbin cover control unit may include a cover control frame that rotates in contact with the discharge cover of the dustbin (220), a motor that provides power to the cover control frame, and a power transmission member (e.g., a link) for transmitting power of the motor. Accordingly, the cover control frame may control the angle at which the discharge cover rotates, and the dustbin (220)

[0111] Although not shown, the vacuum cleaner station (100) of the present invention may include a dust collection unit. The dust collection unit may be positioned inside the housing (110). The dust collection unit may be positioned below the gravity direction of the coupling unit (120).

[0112] For example, the dust collection unit may refer to a dust bag that collects dust sucked from inside the dust bin (220) of the vacuum cleaner (200) by the dust collection motor.

[0113] The dust collection unit can be detachably coupled to the housing (110).

[0114] Accordingly, the dust collector can be separated from the housing (110) and discarded, and a new dust collector can be attached to the housing (110). That is, the dust collector can be defined as a consumable part.

[0115] The dust bag may be provided so that its volume increases when suction power is generated by the dust collection motor, thereby allowing dust to be contained inside.

[0116] To achieve this, the dust bag may be made of a material that is permeable to air but impermeable to foreign substances such as dust. For example, the dust bag may be made of a non-woven material and may have a hexahedral shape when expanded.

[0117] Therefore, user convenience can be improved as there is no need for the user to separately bundle dust-collecting bags, etc.

[0118] Alternatively, the dust bag may include a roll of vinyl (not shown). With this configuration, when the dust bag is sealed or bonded, dust or odors trapped within the dust bag can be prevented from leaking out of the dust bag. At this time, the dust bag can be mounted to the housing (110) via a dust bag cartridge (not shown). If necessary, the dust bag can be replaced via the dust bag cartridge.

[0119] Although not shown, the vacuum cleaner station (100) may include a flow path. The flow path may connect the dust bin (220) of the vacuum cleaner (200) and the dust collection unit. The flow path may be a space formed toward the rear from a dust passage hole (not shown), or may be a flow path formed by bending downward from the dust passage hole (not shown) so that dust and air can flow.

[0120] Dust in the dust bin (220) of the vacuum cleaner (200) can move to the dust collection unit through the euro section.

[0121] Although not shown, the vacuum cleaner station (100) may include a dust suction module. The dust suction module may include a dust collection motor, a first filter (not shown), and a second filter (not shown).

[0122] The dust collector motor may be positioned at the bottom of the dust collection unit. The dust collector motor may generate suction force in the flow path. Through this, the dust collector motor may provide suction force capable of sucking up dust within the dust bin (220) of the vacuum cleaner (200).

[0123] The dust collecting motor can generate suction force by rotation. A first filter (not shown) can be placed between the dust collecting unit and the dust collecting motor. The first filter can be a pre-filter. A second filter (not shown) can be placed between the dust collecting motor and the outer wall (112). The second filter (not shown) can be a HEPA filter.

[0124] Meanwhile, the vacuum cleaner station (100) may further include a charging unit (not shown). The charging unit may be placed in the coupling unit (120). The charging unit (not shown) may be electrically connected to a vacuum cleaner (200) coupled to the coupling unit (120). The charging unit (not shown) may supply power to the battery of the vacuum cleaner (200) coupled to the coupling unit (120).

[0125]

[0126] Referring to Fig. 1, the structure of the vacuum cleaner (200) is described as follows. The vacuum cleaner (200) may refer to a vacuum cleaner that is manually operated by a user. For example, the vacuum cleaner (200) may refer to a handheld vacuum cleaner or a stick vacuum cleaner.

[0127] The cleaner (200) can be mounted on the cleaner station (100). The cleaner (200) can be supported by the cleaner station (100). The cleaner (200) can be coupled to the cleaner station (100).

[0128] Meanwhile, in one embodiment of the present invention, the direction of the vacuum cleaner (200) can be defined based on the time when the bottom surface (lower surface) of the dust bin (220) and the battery housing (230) are placed on the ground.

[0129] At this time, the front may refer to the direction in which the suction part (212) is placed based on the dust bin (220), and the rear may refer to the direction in which the handle (216) is placed based on the dust bin (220). In addition, in one embodiment of the present invention, the upper and lower sides may be defined along a direction perpendicular to the ground when the bottom surface (lower surface) of the dust bin (220) and the battery housing (230) are placed on the ground.

[0130] The vacuum cleaner (200) may include a main body (210). The main body (210) may include a main body housing (211), a suction unit (212), a dust separation unit (not shown), a suction motor (not shown), a handle (216), and an operating unit (218).

[0131] The main body housing (211) may form the exterior of the vacuum cleaner (200). The main body housing (211) may provide a space capable of accommodating a suction motor (not shown) and a filter (not shown) therein. The main body housing (211) may be configured in a shape similar to a cylinder.

[0132] The suction part (212) may protrude outwardly from the main body housing (211). For example, the suction part (212) may be formed in a cylindrical shape with an open interior. The suction part (212) may be coupled to an extension pipe (250). The suction part (212) may provide a path (hereinafter, referred to as a 'suction path') through which air containing dust may flow.

[0133] The dust separation unit (not shown) may be communicated with the suction unit (212). The dust separation unit (not shown) may separate dust sucked into the interior through the suction unit (212). The space inside the dust separation unit (not shown) may be communicated with the space inside the dust bin (220).

[0134] For example, the dust separation unit (not shown) may include at least one cyclone unit capable of separating dust by cyclone flow. In addition, the space inside the dust separation unit (not shown) may be connected to the suction path. Accordingly, the air and dust sucked through the suction unit (212) flow spirally along the inner surface of the dust separation unit (not shown). Accordingly, a cyclone flow may occur in the inner space of the dust separation unit (not shown).

[0135] The dust separation unit (not shown) may further include a secondary cyclone that further separates dust from the air discharged from the cyclone. At this time, the secondary cyclone may be positioned inside the cyclone so as to minimize the size of the dust separation unit. The secondary cyclone may include a plurality of cyclone bodies arranged in parallel. The air discharged from the cyclone may be divided and passed through the plurality of cyclone bodies.

[0136] At this time, the axis of the cyclone flow of the secondary cyclone can also be extended in the vertical direction, and the axis of the cyclone flow of the cyclone and the axis of the cyclone flow of the secondary cyclone can form a coaxial axis in the vertical direction, which can be collectively referred to as the axis of the cyclone flow of the dust separation unit (not shown).

[0137] A suction motor (not shown) can generate a suction force to suck in air. The suction motor (not shown) can be accommodated within the main body housing (211). The suction motor (not shown) can generate a suction force by rotation.

[0138] An air exhaust cover (215) may be placed on one axial side of the main body housing (211). A filter for filtering air may be accommodated in the air exhaust cover (215).

[0139] An air exhaust port may be formed in the air exhaust cover (215) to exhaust air sucked in by the suction force of a suction motor (not shown).

[0140] The handle (216) can be held by the user. The handle (216) can be positioned at the rear of the suction motor (not shown). For example, the handle (216) can be formed in a shape similar to a cylinder. Alternatively, the handle (216) can be formed in a curved cylinder shape. The handle (216) can be positioned at a predetermined angle with respect to the main body housing (211), the suction motor (not shown), or the dust separator (not shown).

[0141] The handle (216) may include a grip portion formed in a column shape so that a user can grip it, a first extension portion connected to one longitudinal (axial) end of the grip portion and extending toward a suction motor (not shown), and a second extension portion connected to the other longitudinal (axial) end of the grip portion and extending toward a dust bin (220).

[0142] The upper surface of the handle (216) may form a portion of the outer appearance of the upper surface of the vacuum cleaner (200). This prevents the components of the vacuum cleaner (200) from coming into contact with the user's arm when the user holds the handle (216).

[0143] The operating unit (218) may be placed on the handle (216). The operating unit (218) may be placed on an inclined surface formed in the upper area of ​​the handle (216). The user may input an operation or stop command for the cleaner (200) through the operating unit (218).

[0144] The vacuum cleaner (200) may include a dust bin (220). The dust bin (220) may be connected to a dust separation unit (not shown). The dust bin (220) may store dust separated from the dust separation unit (not shown).

[0145] The dustbin (220) may include a dustbin body (221), a discharge cover (not shown), a dustbin compression lever (223), and a compressor (not shown).

[0146] The dustbin body (221) can provide a space for storing dust separated from a dust separation unit (not shown). For example, the dustbin body (221) can be formed in a shape similar to a cylinder.

[0147] An extension line of the longitudinal axis of the dust bin (220) can be formed along a direction intersecting the suction path.

[0148] The lower surface (bottom surface) of the dustbin body (221) can be partially opened.

[0149] The dustbin (220) may include a discharge cover (not shown). The discharge cover (not shown) may be placed on the lower surface of the dustbin (220).

[0150] A discharge cover (not shown) may be provided to open and close one end in the longitudinal direction of the dustbin body (221). Specifically, the discharge cover (not shown) may selectively open and close the lower part of the dustbin (220) that opens downward.

[0151] The discharge cover (not shown) may be hinge-connected to the dustbin body (221), and a torsion spring may be provided at the hinge portion. Accordingly, when the discharge cover (not shown) is separated from the dustbin body (221), the cover may be supported by the elastic force of the torsion spring in a state of being rotated by a predetermined angle or more about the hinge portion as an axis.

[0152] The discharge cover (not shown) can be coupled to the dustbin body (221) through a hook connection. Meanwhile, the discharge cover (not shown) can be separated from the dustbin body (221) through a coupling lever (not shown). The coupling lever (not shown) can be arranged at the front of the dustbin. Specifically, the coupling lever (not shown) can be arranged on the outer surface of the front side of the dustbin (220). When an external force is applied, the coupling lever (not shown) can elastically deform the hook to release the hook connection between the discharge cover (not shown) and the dustbin body (221).

[0153] When the discharge cover (not shown) is closed, the lower side of the dust bin (220) may be blocked (sealed) by the discharge cover (not shown).

[0154] The dustbin (220) may include a dustbin compression lever (223). The dustbin compression lever (223) may be disposed outside the dustbin (220) or the dust separation unit (not shown). The dustbin compression lever (223) may be disposed outside the dustbin (220) or the dust separation unit (not shown) so as to move up and down. The dustbin compression lever (223) may be connected to a compressor (not shown). When the dustbin compression lever (223) moves downward by an external force, the compressor (not shown) may also move downward. This may provide convenience to the user. The compressor (not shown) and the dustbin compression lever (223) may return to their original positions by an elastic member (not shown).

[0155] A compressor (not shown) may be placed inside the dustbin body (221). The compressor may move within the internal space of the dustbin body (221). Specifically, the compressor may move up and down within the dustbin body (221). Through this, the compressor may compress the dust within the dustbin body (221) downward.

[0156] The vacuum cleaner (200) may include a battery housing (230). The battery housing (230) may accommodate a battery (240). The battery housing (230) may be positioned on the lower side of the handle (216).

[0157] The battery housing (230) may include a receiving portion that opens downward. The battery (240) may be removed through the receiving portion of the battery housing (230).

[0158] The vacuum cleaner (200) may include a battery (240).

[0159] In contrast, the battery (240) may be integrally provided inside the battery housing (230). In this case, the lower surface of the battery (240) is not exposed to the outside.

[0160] The battery (240) can supply power to the suction motor (not shown) of the vacuum cleaner (200). The battery (240) can be placed at the bottom of the handle (216). The battery (240) can be placed at the rear of the dust bin (220).

[0161] The vacuum cleaner (200) may include an extension pipe (250). The extension pipe (250) may be connected to a cleaning module (260). The extension pipe (250) may be connected to a main body (210). The extension pipe (250) may be connected to a suction unit (212) of the main body (210). The extension pipe (250) may be formed in a cylindrical shape.

[0162] The main body (210) can be connected to an extension pipe (250). The main body (210) can be connected to a cleaning module (260) through the extension pipe (250). The main body (210) can generate suction force through a suction motor (not shown) and provide suction force to the cleaning module (260) through the extension pipe (250). External dust can be introduced into the main body (210) through the cleaning module (260) and the extension pipe (250).

[0163] The vacuum cleaner (200) may include a cleaning module (260). The cleaning module (260) may be connected to an extension pipe (250) through a connection portion (266). Accordingly, external air may be drawn into the main body (210) of the vacuum cleaner (200) through the cleaning module (260) and the extension pipe (250) by the suction force generated in the main body (210) of the vacuum cleaner (200).

[0164] The cleaning module (260) can be configured in various forms depending on the cleaning environment.

[0165] For example, the cleaning module (260) may be a suction nozzle. The suction nozzle may include a suction port through which dust is drawn in and an agitator that rotates above the suction port and guides the dust toward the suction port. When the suction motor (not shown) is operated, the agitator also rotates to guide dust from the surface to be cleaned to the suction port, and then, using the suction force of the suction motor, the dust can be sucked into the dust bin (220).

[0166] As another example, the cleaning module (260) may be a mop nozzle. The mop nozzle (260) may include a body (261), a water tank (262) for storing water, a pair of rotating plates (264) and a pair of mops (265) coupled to the rotating plates and rotating together with the rotating plates. Accordingly, when the mop nozzle is operated, water stored in the water tank is discharged to the pair of mops, and the mops rotate according to the rotation of the rotating plates to clean the surface to be cleaned. Meanwhile, the mop nozzle may further include a heat generator that heats the water in the water tank and discharges it to the mop as high-temperature water or steam. In this case, the cleaning performance of the surface to be cleaned is improved.

[0167] Dust inside the dust bin (220) of the vacuum cleaner (200) can be collected by the dust collection unit of the vacuum cleaner station (100) by gravity and the suction power of the dust collection motor. This allows the dust inside the dust bin to be removed without any separate operation from the user, thereby providing user convenience. In addition, the inconvenience of having to empty the dust bin every time can be eliminated. In addition, when the dust bin is emptied, dust can be prevented from flying around.

[0168] The vacuum cleaner (200) can be coupled to the side of the housing (110). Specifically, the main body (210) of the vacuum cleaner (200) can be mounted on the coupling part (120).

[0169]

[0170] Meanwhile, the conventional vacuum cleaner station (100) is capable of collecting dust from the dust bin (220) of the vacuum cleaner (200), but the cleaning module (260) can only be mounted on the vacuum cleaner station (100), and no structure for managing the cleaning module (260) is disclosed.

[0171] In particular, when the cleaning module (260) is a mop nozzle, the mop (265) remains wet after cleaning is completed or immediately after washing the mop (265), so bacteria may multiply, which may result in an unpleasant odor or contamination.

[0172] Accordingly, a device capable of storing a wet mop (265) and drying it at the same time is required.

[0173] To solve this problem, the present invention further includes a drying module (300) that is coupled to the cleaning station (100) and can dry the mop.

[0174] Below, we will describe this in detail.

[0175]

[0176] FIG. 2 is a drawing for explaining a drying module according to an embodiment of the present invention, FIG. 3 is a drawing for explaining a state in which a mop nozzle is coupled to a drying module for a mop nozzle according to an embodiment of the present invention, FIG. 4 is a drawing for explaining a process in which a drying module for a mop nozzle according to an embodiment of the present invention dries a mop nozzle, FIG. 5 is a drawing for explaining a state in which a drying rack is coupled to a drying module for a mop nozzle according to an embodiment of the present invention, and FIG. 6 is a drawing for explaining a process in which a drying module for a mop nozzle according to an embodiment of the present invention dries a mop mounted on a drying rack.

[0177] Referring to FIGS. 2 to 6, a drying module (300) according to one embodiment of the present invention will be described as follows.

[0178] A drying module (300) according to one embodiment of the present invention includes a module housing (310), a nozzle coupling part (320), a heater (330), a fan (335), and an outlet (340).

[0179] At this time, the heater (330) is provided inside the module housing (310), and the nozzle coupling part (320) and the discharge port (340) are formed in the module housing (310).

[0180] The module housing (310) forms the exterior of the drying module (300) according to one embodiment of the present invention and is detachably coupled to the cleaner station (100).

[0181] Specifically, the module housing (310) is detachably coupled to the outer wall surface (112) of the cleaner station (100). For example, the module housing (310) may be detachably coupled to a hook (114) disposed on the third outer wall surface (112c) or the fourth outer wall surface (112d) of the cleaner station (100).

[0182] With this configuration, the drying module (300) can also be installed by utilizing the space where the cleaner station (100) is installed, thereby improving space efficiency.

[0183] The module housing (310) may be formed so that its length in the vertical direction (or vertical direction) is longer than its length in the front-back direction (or horizontal direction) when coupled to the cleaner station (100). Accordingly, space usage in the horizontal direction can be minimized.

[0184] Meanwhile, the module housing (310) may be provided so that a mop (265) can be mounted thereon. Specifically, the module housing (310) may be mounted so that a pair of mops (265) are coupled to a mop nozzle (260). Alternatively, the module housing (310) may be configured so that at least one mop (265) is mounted separately from the mop nozzle (260).

[0185] To this end, the module housing (310) may be formed in a shape in which the upper horizontal length is small and the lower horizontal length is large. That is, the module housing (310) may be formed in a shape in which the upper diameter is narrow and the lower diameter is wide.

[0186] Accordingly, the module housing (310) can be inclined at a predetermined angle with respect to the ground, and the nozzle coupling portion (320) can be placed on the inclined portion. By this configuration, the mop nozzle (260) can be stably coupled to the module housing (310), and the mop nozzle (260) can be prevented from being accidentally separated, falling, and being damaged.

[0187] And, a hanging part (312) may be provided on the upper part of the module housing (310). The hanging part (312) may be detachably connected to a hanging part (114) disposed on the outer wall surface (112) of the cleaner station (100) to support the upper part of the module housing (310).

[0188] With this configuration, the lower part of the module housing (310) is equipped with a mop (265), and the upper part is connected to a cleaner station (100), which has the effect of stably supporting the mop (265) or the mop nozzle (260).

[0189] The module housing (310) may provide a space capable of accommodating components including a heater (330) therein. For example, the module housing (310) may provide a space capable of accommodating a heater (330), a motor (not shown), and a fan (335) therein.

[0190] Meanwhile, an air inlet (311) is formed in the module housing (310). An air inlet (311) through which external air can be introduced may be formed on the outer surface of the module housing (310).

[0191] In addition, a space through which air can flow may be formed inside the module housing (310). For example, a path through which air drawn in from the air inlet (311) can flow to the heater (330) and a path through which air heated by the heater (330) can flow (hereinafter referred to as a “drying path”) may be formed inside the module housing (310). The drying path is formed to communicate with the discharge port (340), so that air heated by the heater (330) can flow to the discharge port (340). Accordingly, the heated air can be discharged through the discharge port (340) to dry the mop (265).

[0192] The nozzle coupling part (320) is placed in the module housing (310) and is provided so that a mop nozzle (260) can be coupled thereto.

[0193] At this time, the drying module (300) is important not only for the installation of the mop nozzle (260), but also for the drying function of the mop nozzle (260), so a ventilated space is required so that the steam or moisture evaporating from the mop (265) can be sufficiently mixed into the air.

[0194] Therefore, a space needs to be formed between the mop nozzle (260) and the nozzle joint (320) through which air (hot air) heated by the heater (330) can pass.

[0195] Accordingly, the nozzle coupling portion (320) can be in contact with and support the mop nozzle (260), but provide a gap in the middle through which air can pass.

[0196] The nozzle coupling portion (320) can be in contact with and support the mop nozzle (260) at at least two points.

[0197] For example, the nozzle coupling part (320) may include a first support part (321), a second support part (322), and a third support part (323). At this time, the first support part (321) may be positioned above the nozzle coupling part (320), the second support part (322) may be positioned below the first support part (321), and the third support part (323) may be positioned below the second support part (322).

[0198] And, the first support member (321) can be joined by fitting the support protrusion (267) of the mop nozzle (260). Although not shown, the first support member (321) can have a protrusion formed so as to be supported by a chin formed on the support protrusion (267). The support protrusion (267) can mean a structure that protrudes from the connecting pipe (266) and supports the mop nozzle (260) by making contact with the ground when the cleaner (200) is placed on the ground.

[0199] Meanwhile, the second support portion (322) and the third support portion (323) may be formed in a curved shape having a predetermined curvature. In this case, the second support portion (322) may be supported by contact with the body (261) of the mop nozzle (260) positioned between a pair of mops (265). In addition, the third support portion (323) may be supported by contact with the front end of the body (261).

[0200] As a result, the nozzle joint (320) supports the mop nozzle (260) at multiple points, but creates a space where air can flow between it and the mop nozzle (260) except for the point of contact, thereby improving the drying efficiency of the mop (265).

[0201] The heater (330) is placed inside the module housing (310) and can heat the air.

[0202] The heater (330) may be placed inside the module housing (310), but may be placed at a lower position than the discharge port (340). By this arrangement, air heated by the heater (330) may naturally flow to the discharge port (340) while ascending convection, thereby increasing flow efficiency and thermal efficiency.

[0203] The heater (330) can generate heat. For example, the heater (330) can be a PTC heater. The heater (330) is a device that can convert electrical energy into thermal energy and can be implemented using a known structure, so a detailed description thereof will be omitted.

[0204] Meanwhile, the drying module (300) of the present invention may further include a fan (335).

[0205] The fan (335) may be a device that generates air flow by rotating according to the driving of a motor (not shown). Since the fan (335) may be implemented by a known structure, a detailed description thereof will be omitted.

[0206] At this time, the fan (335) can flow air toward the heater (330).

[0207] The fan (335) may be placed inside the module housing (310), but may be placed lower than the heater (330). Accordingly, air provided with a flow force through the fan (335) may be heated while passing through the heater (330), thereby adding an upward convection effect, thereby improving the air flow effect.

[0208] Meanwhile, the heater (330), motor (not shown), and fan (335) may be driven by a battery built into the drying module (300). Alternatively, the heater (330), motor (not shown), and fan (335) may be driven by being connected to an external power source. In this case, the drying module (300) may be connected to the external power source. Alternatively, depending on the embodiment, it may be electrically connected to the cleaner station (100) to receive power.

[0209] The outlet (340) may be a space for discharging air heated by the heater (330) to the outside of the drying module (300). The outlet (340) is positioned facing the mop (265). For example, the outlet (340) may be positioned between the second support member (322) and the third support member (323), and may be formed in the form of multiple slits to have a shape similar to a grill.

[0210] Therefore, the hot air discharged through the discharge port (340) can be introduced into the mop (265) and dry the mop (265).

[0211] Meanwhile, the drying module (300) according to one embodiment of the present invention may further include a drying unit (350).

[0212] The drying rack (350) is detachably connected to the module housing (310) and can accommodate at least a portion of the mop (265).

[0213] The drying rack (350) may be provided with a mop (265). For example, the drying rack (350) may be formed in a shape close to a pocket overall. That is, the lower portion of the drying rack (350) may be formed in a curved shape, and the inner space of the drying rack (350) may be formed in a shape in which the diameter increases toward the upper portion and then remains constant. In this case, the lower portion and the upper portion of the drying rack (350) may be formed in an open shape. Accordingly, the mop (265) may be provided in the inner space of the drying rack (350), and at least a portion of the mop (265) may be accommodated in the drying rack (350).

[0214] With this configuration, the mop (265) can be mounted on the drying module (300) separately from the mop nozzle (260) through the drying rack (350).

[0215] The drying rack (350) can be combined with the module housing (310). For example, although not shown, the drying rack (350) may be provided with a clip or protrusion that can be inserted into the discharge port (340) to support the drying rack (350).

[0216] Accordingly, the drying rack (350) and the module housing (310) can be easily combined.

[0217] Meanwhile, the lower part opened in the drying rack (350) can be formed to communicate with the discharge port (340).

[0218] Accordingly, when the heater (330) and fan (335) are operated, the warm air heated by the heater (330) is introduced into the internal space of the drying rack (350) through the outlet (340), and after drying the mop (265), can be discharged into the upper space of the drying rack (350).

[0219] Accordingly, the mop (265) can be placed and dried separately from the mop nozzle (260) through the drying rack (350).

[0220]

[0221] Meanwhile, FIG. 8 illustrates a drawing for explaining a drying module according to another embodiment of the present invention, FIGS. 9 and 10 illustrate drawings for explaining a structure for storing a pet nozzle in a drying module according to another embodiment of the present invention, FIGS. 11 and 12 illustrate drawings for explaining a structure for storing a battery in a drying module according to another embodiment of the present invention, FIGS. 13 and 14 illustrate drawings for explaining a structure for storing an auxiliary battery in a drying module according to another embodiment of the present invention, and FIG. 15 illustrates a drawing for explaining a process for drying a mop nozzle in a drying module according to another embodiment of the present invention.

[0222] Referring to FIGS. 8 to 15, a drying module (1300) according to another embodiment of the present invention will be described as follows.

[0223] Meanwhile, in order to avoid repetitive explanation, the contents not specifically described in this embodiment are the same as the structure and effect of the cleaner station (100) and cleaner (200) according to one embodiment of the present invention, and thus can be cited.

[0224] The drying module (1300) according to the present embodiment includes a module housing (1310), a nozzle coupling part (1320), a heater (1330), a fan (1335), a discharge port (1340), a mop coupling part (1350), and a support wall (1390).

[0225] At this time, the module housing (1310) can be retractably coupled to the lower side of the cleaner station (100).

[0226] Specifically, in this embodiment, a support wall (1390) can be coupled to the bottom surface (111) of the cleaner station (100).

[0227] The support wall (1390) can be coupled to the lower side of the cleaner station (100) to support the cleaner station (100).

[0228] For example, at least two support walls (1390) may be provided and may be coupled to the lower side of the bottom surface (111) of the cleaner station (100). At this time, the support walls (1390) may be formed of a material having sufficient supportive force to support the weight of the cleaner station (100). For example, the support walls (1390) may be formed of a metal material or a resin material.

[0229] The support walls (1390) may be arranged in pairs in parallel or may be arranged to block three sides. Accordingly, a space may be formed between the cleaner station (100) and the ground into which the module housing (1310) may be inserted. Consequently, a space may be formed between at least two support walls (1390) and the ground and the bottom surface (111) of the cleaner station (100) in which at least a portion of the module housing (1310) may be accommodated.

[0230] Accordingly, an entrance through which the module housing (1310) of the drying module (1300) can be introduced and withdrawn can be formed at the lower side of the cleaner station (100).

[0231] For example, the entrance may be formed at the front of the cleaner station (100). That is, the entrance may be formed directly below the surface where the cleaner (200) is coupled. With this configuration, the user can conveniently couple the cleaner (200) to the cleaner station (100), immediately detach the mop module (260), and place it on the drying module (1300) positioned directly below.

[0232] Meanwhile, although not shown, a module base (not shown) may be further provided on the lower side of the support wall (1390). The module base is formed to connect a pair of opposing support walls (1390) and may be positioned to face the ground. In this case, the module housing (1310) may be retractably connected between the support wall (1390), the module base, and the bottom surface (111) of the cleaner station (100).

[0233] Meanwhile, the above-described support wall (1390) and / or module base (not shown) may be installed to be fixed to the cleaner station (100). In this case, the module housing (1310) is coupled within a space fixed to the cleaner station (100), so the module housing (1310) can be expressed as being coupled to the cleaner station (100).

[0234]

[0235] The module housing (1310) forms the exterior of the drying module (1300) according to the present embodiment and is detachably coupled to the cleaner station (100).

[0236] Specifically, the module housing (1310) can be retractably coupled to the lower side of the bottom surface (111) of the cleaner station (100).

[0237] With this configuration, the drying module (1300) can also be installed by utilizing the space where the cleaner station (100) is installed, thereby improving space efficiency.

[0238] As a result, there is an effect that allows management of the mop nozzle (260) using only the narrow space below the cleaner station (100).

[0239] The module housing (1310) may provide a space for storing objects. For example, the module housing (1310) may be formed in a shape similar to a square box, and at least one guide shape capable of guiding the combination of objects may be formed in the internal space.

[0240] For example, the module housing (1310) may include a housing bottom surface (1311) and four side walls (1312) surrounding it, and the four side walls (1312) may be formed in a form that is connected to each other. As a result, a space surrounded by the bottom surface (1311) and the side walls (1312) may be formed. In addition, the module housing (1310) further includes a joining plate (1313) that is arranged in the space and divides the space. The internal space of the module housing (1310) may be divided into an upper space and a lower space based on the joining plate (1313). That is, the internal space of the module housing (1310) includes an upper space formed above the joining plate (1313) and a lower space formed below the joining plate (1313). At this time, the concept of upper and lower may not refer to the height from the ground, but may mean a relative position with the joining plate (1313) as the boundary.

[0241] Meanwhile, the module housing (1310) may provide a space capable of accommodating components including a heater (1330) therein. For example, a space capable of accommodating a heater (1330), a motor (not shown), and a fan (1335) may be provided in the lower space of the module housing (1310).

[0242] Meanwhile, although not shown, an air inlet may be formed in the module housing (1310). An air inlet (not shown) through which external air may be introduced may be formed in the side wall (1312) of the module housing (1310). In this case, the air inlet may be formed close to a fan (1335) described later. Through this, external air may be easily introduced.

[0243] In addition, a space through which air can flow may be formed inside the module housing (1310). For example, a path through which air drawn in from an air inlet (not shown) can flow to a heater (1330) and a path through which air heated by the heater (1330) can flow (hereinafter referred to as a “drying path”) may be formed inside the module housing (1310). The drying path is formed to be in communication with the discharge port (1340), so that air heated by the heater (1330) can flow to the discharge port (1340). Accordingly, the heated air can be discharged through the discharge port (1340) to dry the mop (265) (see FIG. 15).

[0244] Meanwhile, a handle (1315) may be provided on the front surface of the module housing (1310). The handle (1315) may be provided in a manner that allows the user to grasp it. This has the advantage of allowing the user to withdraw the module housing (1310) with a simple action of pulling the handle.

[0245] Meanwhile, although not shown, it is also possible to further equip the lower portion of the module housing (1310) with wheels, depending on the embodiment. If wheels are provided, the force required to pull out the module housing (1310) can be reduced, thereby providing convenience to the user.

[0246] Meanwhile, although not shown, guide rails may be further provided on the side and support wall (1390) of the module housing (1310) according to an embodiment. If further guide rails are provided, the module housing (1310) can be easily withdrawn or inserted after the guide rails of the module housing (1310) and the guide rails of the support wall (1390) are coupled to each other.

[0247] The heater (1330) is placed inside the module housing (1310) and can heat air. The heater (1330) is placed in the lower space of the module housing (1310) and can heat air introduced through the air inlet to generate hot air.

[0248] The heater (1330) may be placed inside the module housing (1310) and may be placed at a lower position than the outlet (1340). By this arrangement, air heated by the heater (1330) may naturally flow to the outlet (1340) while ascending convection, thereby increasing flow efficiency and thermal efficiency.

[0249] The heater (1330) can generate heat. For example, the heater (1330) can be a PTC heater. The heater (1330) is a device that can convert electrical energy into thermal energy and can be implemented using a known structure, so a detailed description thereof will be omitted.

[0250] Meanwhile, the drying module (1300) of the present invention may further include a fan (1335).

[0251] The fan (1335) may be a device that generates air flow by rotating according to the driving of a motor (not shown). Since the fan (1335) may be implemented by a known structure, a detailed description thereof will be omitted.

[0252] At this time, the fan (1335) can flow air toward the heater (1330).

[0253] The fan (1335) may be positioned inside the module housing (1310), but closer to the air inlet than the heater (1330). The fan (1335) may be positioned in the lower space of the module housing (1310), but further from the coupling plate (1313) than the heater (1330).

[0254] The outlet (1340) may be a space for discharging air heated by the heater (1330) into the upper space. The outlet (1340) may be a space formed in the coupling plate (1313). In this case, the outlet (1340) is positioned facing the mop (1265). For example, the outlet (1340) may be formed in the mop receiving portion (1321) of the nozzle coupling portion (1320) described below.

[0255] Therefore, the hot air discharged through the discharge port (1340) can be introduced into the mop (265) and dry the mop (265).

[0256] Meanwhile, various accessories, including a mop nozzle (260), can be stored in the upper space of the module housing (1310). At this time, a shape for guiding the attachment position of the accessory can be formed on the coupling plate (1313).

[0257] Accordingly, the drying module (1300) according to the present embodiment may be provided with at least one joint formed through a joint plate (1313).

[0258] At this time, the module housing (1310) may be provided so that a mop (265) can be placed thereon. Specifically, the module housing (1310) may be placed so that a pair of mops (265) are coupled to a mop nozzle (260). Alternatively, the module housing (1310) may be placed so that at least one mop (265) is placed separately from the mop nozzle (260).

[0259] Meanwhile, although not shown, the drying module (1300) according to the present embodiment may further include a water reservoir. The water reservoir may serve to collect moisture contained in the mop (265). At this time, a portion of a discharge port (1340) may be formed in the water reservoir to dry the water stored in the water reservoir.

[0260] Meanwhile, although not shown, the drying module (1300) according to the present embodiment may further include an exhaust port. The exhaust port may discharge moist air generated during the drying process of the mop (265) to the outside. When the drying module (1300) is operated, the interior of the drying module (1300) may become hot and humid, and if this state persists, it may cause a failure of a number of electrical devices, including the battery (240) mounted on the drying module (1300). Therefore, an exhaust port may be formed in the support wall (1390) and / or the module housing (1310), to discharge heated and humidified air.

[0261] Meanwhile, although not shown, the drying module (1300) according to the present embodiment may further include a sterilizing device. For example, the sterilizing device may be a light source capable of irradiating ultraviolet rays. In the case of an object that is washed with water, such as a mop (265), it is necessary to expose it to ultraviolet rays not only for drying but also for sterilization. Therefore, the drying module (1300) may further include a sterilizing device in the mop receiving portion (1321) and / or the mop connecting portion (1350), which will be described later, to prevent the proliferation of bacteria on the mop (265).

[0262] For example, as illustrated in FIGS. 9 and 10, the drying module (1300) may include a nozzle coupling portion (1320), a mop coupling portion (1350), a second nozzle coupling portion (1360), and an auxiliary battery coupling portion (1380).

[0263] The nozzle coupling part (1320) can be coupled to a mop nozzle (260) at the top. At this time, a mop receiving part (1321) is formed in the nozzle coupling part (1320), and a pair of mops (265) coupled to a pair of rotating plates (264) can be mounted thereon. A discharge port (1340) is formed in the mop receiving part (1321), which has the effect of allowing the mop (265) to be dried and sterilized with hot air.

[0264] In addition, a separate mop (265) separated from the mop nozzle (260) can be connected to the mop coupling part (1350). A dried mop (265) can be stored in the mop coupling part (1350). Alternatively, the lower part of the mop coupling part (1350) can be formed to be in communication with the drying path, so that only the mop (265) can be dried separately.

[0265] The second nozzle coupling part (1360) can be coupled with a relatively small cleaning module (260`), including a pet nozzle, crevice nozzle, or bedding nozzle.

[0266] The auxiliary battery coupling part (1380) is formed in a form that is connected to the nozzle coupling part (1320), and can be coupled with the auxiliary battery (268) coupled to the connection part (266) of the mop nozzle (260).

[0267] As another example, as illustrated in FIGS. 11 and 12, the drying module (1300) may include a nozzle coupling portion (1320), a mop coupling portion (1350), a battery coupling portion (1370), and an auxiliary battery coupling portion (1380).

[0268] The battery coupling unit (1370) can be coupled to the upper portion of the battery (240) used in the main body (210) or cleaning module (260) of the vacuum cleaner (200). Accordingly, the battery (240) can be stored therein to replace the battery of the main body (210) or cleaning module (260) of the vacuum cleaner, if necessary. Meanwhile, although not shown, the battery coupling unit (1370) can also be further provided with an electrical terminal. In this case, it is possible to store the battery (240) and supply power to the battery (240) to charge the battery (240).

[0269] As another example, as illustrated in FIGS. 13 and 14, the drying module (1300) may include a nozzle coupling portion (1320), a mop coupling portion (1350), and an auxiliary battery coupling portion (1380).

[0270] At this time, the auxiliary battery coupling part (1380) can be positioned separately from the nozzle coupling part (1320). Accordingly, a separate auxiliary battery (268) separated from the connection part (266) of the mop nozzle (260) can be coupled to the auxiliary battery coupling part (1380).

[0271] In addition, although not shown, the drying module (1300) may include various combinations including at least one of a nozzle coupling (1320), a mop coupling (1350), a second nozzle coupling (1360), a battery coupling (1370), and an auxiliary battery coupling (1380).

[0272] Therefore, according to the present invention, it is possible to store a relatively large mop nozzle (260) among the cleaning modules, while simultaneously storing various accessories and drying the mop (265).
