Description

vacuum cleaner mop module

[0001] The present invention relates to a mop module of a vacuum cleaner, and more specifically, to a mop module of a vacuum cleaner that discharges water onto a mop to suck up or wipe dust or foreign matter in a cleaning target area.

[0002]

[0003] A vacuum cleaner is a device that performs cleaning by sucking up or wiping away dust or foreign matter from an area to be cleaned.

[0004] These vacuum cleaners can be classified into manual vacuum cleaners, which are operated by the user moving the vacuum cleaner themselves, and automatic vacuum cleaners, which operate by driving themselves.

[0005] In addition, manual vacuum cleaners can be classified into canister-type vacuum cleaners, upright-type vacuum cleaners, handheld vacuum cleaners, stick-type vacuum cleaners, etc., depending on the form of the vacuum cleaner.

[0006] Floor cleaning methods are broadly divided into dry cleaning and wet cleaning. Dry cleaning is a method of cleaning by sweeping or sucking up dust, and conventional vacuum cleaners fall into this category. Wet cleaning is a method of cleaning by wiping away dust with a wet mop.

[0007] Conventionally, a dedicated dry cleaner was used for dry cleaning, and a dedicated wet cleaner was used for wet cleaning. However, there was the inconvenience of having to purchase two types of cleaners to clean various types of floors. To solve the aforementioned problem, a method was researched in which a single main body, a dry cleaning module, and a wet cleaning module are provided, so that the dry cleaning module is attached to the main body for dry cleaning, and the wet cleaning module (mop module) is attached to the main body for wet cleaning.

[0008] However, when wet cleaning, if foreign matter is stuck to the floor, the foreign matter may still remain even if you wipe the floor by rotating a mop soaked in water.

[0009] In addition, there is a limitation in that if microorganisms have proliferated on the floor, even if a water-absorbed mop is rotated to wipe the floor, the microorganisms may not be completely sterilized.

[0010] To solve this, one can consider a method of heating water through a heater to supply high-temperature water or steam to the mop.

[0011] At this time, the steam mop module includes a water tank for storing water, a heater for heating water to generate steam, and a mop that receives water or steam to wipe the floor. Here, it is preferable that each component be configured as a single assembly to facilitate replacement. For example, if the water tank or heater is placed in the main body, it becomes an unnecessary component during dry cleaning, and cleaning becomes inconvenient due to the weight of the water tank or heater. Therefore, in terms of ease of cleaning, ease of module replacement, and space utilization, it is preferable that the water tank or heater be placed in the steam mop module rather than the main body of the vacuum cleaner.

[0012] Korean registered patent KR1609444B1 (March 30, 2016) discloses a water cleaner equipped with a steam generating means.

[0013] In the above-mentioned water cleaner, both the water supply port and the steam discharge port are positioned above the steam generating means, and the water supply port and the steam discharge port are connected by a U-shaped pipe.

[0014] As such, in conventional heating generators, the steam discharge port is generally positioned on the upper side of the heating generator.

[0015] However, even if steam is supplied through the mop, the steam heated by the heater has a relatively lower density compared to water and rises upward, and a limitation may occur where water, rather than steam, is mainly supplied to the mop placed below the heater.

[0016] In addition, as the mop module moves along the floor surface, the heater may shake, causing the water flowing inside the heater to be discharged onto the mop without being sufficiently heated.

[0017] In addition, since the above vacuum cleaner has one heater connected to one power source, it has a limitation in that a large amount of power must be supplied to the mop module when heating water, which may result in a limitation on cleaning time.

[0018]

[0019] The present invention was created to improve upon the problems of conventional mop modules of vacuum cleaners as described above, and aims to provide a mop module for a vacuum cleaner that increases the sterilization and foreign matter removal effects by supplying high-temperature water or steam to the mop.

[0020] In addition, the purpose is to provide a mop module for a vacuum cleaner that can be heated to a target temperature while water flowing into a heating generator is flowing.

[0021] In addition, the purpose is to provide a mop module for a vacuum cleaner that can maintain a long operating time of the heating generator.

[0022] In addition, the purpose is to provide a mop module for a vacuum cleaner that can prevent the heating generator from overheating.

[0023] In addition, the purpose is to provide a mop module for a vacuum cleaner that can adjust the temperature and phase of the moisture supplied to the mop according to the selection.

[0024]

[0025] To achieve the above-mentioned purpose, a mop module of a vacuum cleaner for cleaning foreign substances on a floor surface comprises: a module housing; a water tank coupled to the module housing and storing water inside; at least one rotating cleaning unit disposed below the module housing and to which a mop can be attached; and a heating generator for heating water supplied from the water tank; wherein the heating generator comprises: a heating chamber having a flow path formed therein for water to flow; and a heater disposed below the heating chamber and supplying heat to the heating chamber; wherein the heater is provided in multiple numbers and can operate independently of each other.

[0026] At this time, the mop module of the vacuum cleaner of the present invention further includes a module battery that supplies power to the heating generator; and the module battery can supply power to any one of the plurality of heaters.

[0027] At this time, any one of the plurality of heaters can receive power from the main battery provided in the vacuum cleaner body.

[0028] In addition, multiple of the above heaters can be powered by different batteries.

[0029] Meanwhile, the heating generator may include a temperature detection unit for measuring the temperature of the heating chamber.

[0030] At this time, the temperature detection unit is disposed within the heating chamber, and the temperature detection unit may be disposed at a position facing at least a portion of each of the plurality of heaters with respect to the bottom surface of the heating chamber.

[0031] The heater may include a first heater that receives power from a main battery provided in the main body of the vacuum cleaner; and a second heater that receives power from the module battery.

[0032] Meanwhile, the heater may further include a heater housing that accommodates the first heater and the second heater inside.

[0033] At this time, the heater housing may have a partition wall formed therein that separates the first heater and the second heater.

[0034] Meanwhile, the heating wire of the first heater is formed by bending it multiple times at regular intervals, and the heating wire of the second heater is formed by bending it multiple times and can be placed between the intervals of the heating wire of the first heater.

[0035] Meanwhile, the first heater and the second heater can be operated optionally.

[0036] In contrast, the first heater and the second heater can be operated simultaneously.

[0037] Meanwhile, if the temperature measured by the temperature detection unit is higher than a preset reference temperature, the operation of the first heater or the second heater may be stopped.

[0038]

[0039] As explained above, the mop module of the vacuum cleaner according to the present invention has the effect of increasing the sterilization and foreign matter removal effects by supplying high-temperature water or steam to the mop through a heater.

[0040] In addition, flow guide walls and flow delay protrusions are formed in the heating chamber, which has the effect of allowing water introduced into the heating generator to be heated to a target temperature while flowing.

[0041] In addition, by connecting multiple heaters to the main battery of the main body and the module battery of the mop module, respectively, and controlling them independently, it is possible to maintain the operating time of the heating generator for a long time.

[0042] In addition, it is effective to provide a mop module for a vacuum cleaner that measures the temperature through a temperature detection unit and controls a heater to adjust the temperature and phase of the moisture supplied to the mop according to selection.

[0063] Preferred embodiments of the present invention will be described in detail below with reference to the attached drawings.

[0064] The present invention is capable of various modifications and may have various embodiments, and specific embodiments are illustrated in the drawings and described in detail in the detailed description. This is not intended to limit the present invention to specific embodiments, and should be interpreted to include all modifications, equivalents, and substitutions that fall within the spirit and scope of the invention.

[0065]

[0066] FIG. 1 shows a perspective view of a vacuum cleaner according to an embodiment of the present invention, FIG. 2 and FIG. 3 show an assembled perspective view and an exploded perspective view for explaining a mop module according to an embodiment of the present invention, FIG. 4 to FIG. 6 show a state in which the upper housing is removed from the mop module according to an embodiment of the present invention, FIG. 7 shows a rear view looking at the rear side of the mop module according to an embodiment of the present invention, and FIG. 8 shows a cross-sectional view of the mop module according to an embodiment of the present invention.

[0067] In this specification, "floor surface" can be understood to mean not only the floor surface of a living room or room, but also a clean surface such as a carpet.

[0068] Referring to FIGS. 1 to 8, a vacuum cleaner (1) according to one embodiment of the present invention may include a vacuum cleaner body (400) having a suction motor for generating suction force, a mop module (100) connected to the vacuum cleaner body (400) for sucking air and foreign matter from a floor surface and cleaning the floor surface by wiping it, and an extension tube (300) connecting the vacuum cleaner body (400) and the mop module (100).

[0069]

[0070] A mop module (100) according to an embodiment of the present invention may include a module housing (110) and a connecting pipe (180) movably connected to the module housing (110).

[0071] The mop module (100) of this embodiment can be connected to and used with, for example, a handheld vacuum cleaner or a canister-type vacuum cleaner.

[0072] That is, the mop module (100) can be detachably connected to the vacuum cleaner body (400) or the extension tube (300). As the mop module (100) is connected to the vacuum cleaner body (400) or the extension tube (300), the user can clean the floor surface using the mop module (100). At this time, the vacuum cleaner body (400) to which the mop module (100) is connected can separate dust from the air using a multi-cyclone method.

[0073] The mop module (100) can be operated by receiving power from the vacuum cleaner body (400). Specifically, the mop module (100) can be operated by receiving power from the main battery (410) provided in the vacuum cleaner body (400).

[0074] The vacuum cleaner body (400) to which the mop module (100) is connected includes a suction motor (not shown), so the suction force generated by the suction motor (not shown) can be applied to the mop module (100).

[0075] Accordingly, in this embodiment, the mop module (100) can perform the role of sucking up foreign matter and air from the floor surface and guiding it to the vacuum cleaner body (400).

[0076] The connecting pipe (180) is connected to the rear central part of the module housing (110) and can guide the sucked air to the vacuum cleaner (1), but is not limited thereto.

[0077] To aid understanding, the direction of this embodiment can be defined as follows: the part where the connecting pipe (180) is connected to the mop module (100) can be said to be the rear (back) of the mop module (100), and the opposite side of the part where the connecting pipe (180) is connected can be said to be the front (front) of the mop module (100). Additionally, the direction connecting the front and the rear can be called the front-back direction.

[0078] Additionally, based on the view of the suction port (113a) from the connecting pipe (180), the left side of the flow path forming part (113) can be referred to as the left side of the mop module (100), and the right side of the flow path forming part (113) can be referred to as the right side of the mop module (100). Furthermore, the direction connecting the left and right sides can be referred to as the left-right direction. The left-right direction may refer to a direction perpendicular to the front-back direction and the horizontal plane.

[0079] Additionally, based on the state in which the mop module (100) is placed on the floor surface, that is, based on the state in which the mop (150) is placed on the floor surface and can wipe the floor surface, the direction closer to the floor surface can be called the lower side or downward direction, and the direction further away from the floor surface can be called the upper side or upward direction.

[0080] The mop module (100) may further include a rotating cleaning unit (140) rotatably provided on the lower side of the module housing (110). For example, the rotating cleaning unit (140) may be a rotating plate formed in the shape of a disc.

[0081] For example, the rotary cleaning unit (140) may be provided in a pair and arranged in a left-right direction. At this time, the pair of rotary cleaning units (140) may rotate independently. For example, the rotary cleaning unit (140) may include a first rotary cleaning unit (141) and a second rotary cleaning unit (142).

[0082] The rotating cleaning unit (140) can be combined with a mop (150). The mop (150) can be formed in the shape of a disc, for example. The mop (150) may include a first mop (151) and a second mop (152).

[0083] When the mop (150) is placed on the floor surface, the mop (150) is in close contact with the floor surface due to the load of the wet mop module (100), so the frictional force between the mop (150) and the floor surface increases.

[0084] The module housing (110) forms the outer shape of the mop module (100) and may have an intake port (113a) formed therein for sucking in air. The intake port (113a) may, for example, be formed at the lower front end of the module housing (110). The intake port (113a) may be formed extending in the left-right direction from the module housing (110).

[0085] The module housing (110) may include a lower housing (111) and an upper housing (112) coupled to the upper side of the lower housing (111).

[0086] The lower housing (111) is equipped with a rotating cleaning unit (140) and can form the shape of a mop module (100).

[0087] The lower housing (111) may include a bottom surface (111a) to which a rotating cleaning unit (140) is attached. At this time, the lower side of the bottom surface (111a) is positioned to face the floor surface when the mop module (100) is placed on the floor surface, and a water supply unit (130), a heating generator (200), and a driving motor (170) may be provided on the upper side of the bottom surface (111a).

[0088] A suction port (113a) may be formed in the lower housing (111). Specifically, a suction port (113a) may be formed on the bottom surface (111a) of the lower housing (111). The suction port (113a) refers to a space into which air containing dust can be introduced. With this configuration, when the suction motor (not shown) of the vacuum cleaner body (400) is operated, dust and air present around the floor surface can be sucked into the flow path of the mop module (100) through the suction port (113a).

[0089] The lower housing (111) may be provided with a board mounting portion in which a printed circuit board (190) for controlling a drive motor (170) is installed. For example, the board mounting portion may be formed in the shape of a hook extending upward from the lower housing (111).

[0090] Although not limited to this, the substrate mounting portion may be located on one side of the flow path forming portion (113) in the lower housing (111). For example, the printed circuit board (190) may be positioned adjacent to the first operating portion (191) and the second operating portion (192). Accordingly, a switch installed on the printed circuit board (190) can detect the operation of the first operating portion (191) and the second operating portion (192).

[0091] A nozzle hole (not shown) for a diffuser (137) to pass through may be formed in the lower housing (111). Water or steam (water vapor) that has passed through the heating generator (200) and the diffuser (137) through the nozzle hole (not shown) may be supplied to the mop (150).

[0092] Meanwhile, a light-emitting module (160) may be provided in the lower housing (111). Specifically, a light-emitting module (160) may be provided on the front of the lower housing (111).

[0093] The upper housing (112) covers the upper side of the lower housing (111) and can form the outer shape of the mop module (100) of the present invention.

[0094] Additionally, the module housing (110) may further include a flow path forming part (113) that communicates with the suction port (113a) and forms a flow path that guides air entering from the suction port (113a) to the main body (400) of the vacuum cleaner.

[0095] The Euro forming part (113) can be coupled to the upper central part of the lower housing (111), and the end can be connected to the connecting pipe (180).

[0096] Therefore, by arranging the flow path forming part (113), the suction port (113a) can be extended in a roughly straight line in the front-rear direction, so the length of the suction port (113a) can be minimized, and thus the loss of the flow path in the mop module (100) can be minimized.

[0097] The front portion of the flow path forming portion (113) can cover the upper side of the intake port (113a). The flow path forming portion (113) can be arranged to slope upward from the front portion toward the rear portion. That is, the upper surface of the flow path forming portion (113) can be sloped at a predetermined angle with respect to the bottom surface. Additionally, the upper surface of the flow path forming portion (113) can be sloped at a predetermined angle with respect to the bottom surface (111a) of the lower housing (111).

[0098] Accordingly, the Euro forming part (113) can be formed such that the height of the front part is lower than that of the rear part.

[0099] According to the present embodiment, since the height of the front part of the flow path forming part (113) is low, there is an advantage in that the height of the front part of the total height of the mop module (100) can be reduced. The lower the height of the mop module (100), the higher the possibility of being inserted into and cleaning narrow spaces on the underside of furniture or chairs.

[0100] Meanwhile, in this embodiment, a heating generator (200) may be positioned on the upper side of the Euro forming part (113). With this configuration, the heating generator (200) can be stably supported in a positioned at a predetermined angle with respect to the bottom surface.

[0101]

[0102] A blocker (114) is disposed on the lower surface of the lower housing (111) (the lower surface of the bottom surface (111a)). The blocker (114) can block the front space where the suction port (113a) is disposed and the rear space where the mop (150) is disposed, thereby blocking moisture released from the mop (150) from spreading to the suction port (113a). For example, the blocker (114) may include a central part (114a) and an extension part (114b). At this time, a pair of extension parts (114b) may be symmetrically connected to both ends based on the central part (114a). Also, the central part (114a) is disposed behind the suction port (113a) to block moisture from flowing toward the suction port (113a). And, the extension part (114b) can be provided in an arc shape to surround the circular mop (150).

[0103] A plurality of rollers may be provided on the lower side of the bottom surface (111a) of the lower housing (111) to facilitate the smooth movement of the mop module (100).

[0104] For example, a front roller (115) may be positioned in front of the mop (150) in the lower housing (111). The front roller (115) may include a first roller (115a) and a second roller (115b). The first roller (115a) and the second roller (115b) may be spaced apart in the left and right directions.

[0105] The first roller (115a) and the second roller (115b) can each be rotatably connected to a shaft. The shaft can be fixed to the lower side of the lower housing (111) while positioned to extend in the left-right direction.

[0106] The distance between the shaft and the front portion of the lower housing (111) is longer than the minimum distance between the mop (150) and the front portion of the lower housing (111).

[0107] For example, at least a portion of the rotating cleaner (140) may be positioned between the shaft of the first roller (115a) and the shaft of the second roller (115b).

[0108] According to this arrangement, the rotating cleaning unit (140) can be positioned as close as possible to the suction port (113a), and the area cleaned by the rotating cleaning unit (140) on the floor surface where the mop module (100) is located can be increased, thereby improving floor cleaning performance.

[0109] In the case of the present embodiment, since the first roller (115a) and the second roller (115b) are coupled to the lower side of the lower housing (111), the mobility of the mop module (100) can be improved.

[0110] A third roller (116) may be further provided in the lower housing (111). Thus, the first roller (115a) and the second roller (115b) together with the third roller (116) can support the mop module (100) at three points. At this time, the third roller (116) may be positioned at the rear of the mop (150) so as not to interfere with the mop (150).

[0111] A cooling air inlet (117) may be formed in the lower housing (111). External air may be introduced into the interior of the module housing (110) through the cooling air inlet (117). Additionally, the cooling air inlet (117) may be formed on the front side wall of the lower housing (111). With this configuration, the amount of air introduced may be increased when the mop module (100) moves forward by user operation.

[0112] A cooling air outlet (118) may be formed in the upper housing (112). Air inside the module housing (110) may be discharged to the outside through the cooling air outlet (118). Additionally, the cooling air outlet (118) may be formed on both side walls of the upper housing (112). With this configuration, the air introduced through the cooling air inlet (117) can be guided to pass through the drive motor (170) as it flows to the cooling air outlet (118), and there is an advantage in that the drive motor (170) can be prevented from overheating.

[0113] Also, based on the state where the lower housing (111) is placed on the floor, the cooling air outlet (118) can be positioned further from the ground than the cooling air inlet (117). With this configuration, the heated air inside the module housing (110) can rise and be effectively discharged to the cooling air outlet (118).

[0114]

[0115] The mop module (100) may further include a water tank (120) to supply moisture to the mop (150).

[0116] The water tank (120) can be detachably connected to the module housing (110). Specifically, the water tank (120) can be coupled to the upper side of the upper housing (112). For example, the water tank (120) can be mounted on a water tank mounting portion formed on the upper side of the upper housing (112).

[0117] Additionally, the water tank (120) may be positioned above the heating generator (200). Specifically, the water tank (120) is positioned above the heating generator (200) at a distance from the heating generator (200). That is, the water tank (120) may be positioned above the heating generator (200) with the upper housing (112) in between.

[0118] With the water tank (120) mounted in the module housing (110), the water tank (120) can form the exterior of the mop module (100).

[0119] In effect, the entire upper wall of the water tank (120) can form the upper surface of the mop module (100). Thus, the user can visually check whether the water tank (120) is mounted in the module housing (110).

[0120] The module housing (110) may further include a water tank separation button operated to separate the water tank (120) while the water tank (120) is mounted in the module housing (110). For example, the water tank separation button may be located in the center of the mop module (100). Thus, there is an advantage that the user can easily recognize the water tank separation button and operate the water tank separation button.

[0121] When the water tank (120) is mounted on the module housing (110), water from the water tank (120) can be supplied to the mop (150). Specifically, water stored in the water tank (120) can be supplied to the mop (150) through the water supply unit (130).

[0122] Specifically, a space for storing water is formed inside the water tank (120). The water stored in the water tank (120) can be supplied to a heating generator (200) through at least one pipe (hose). The water introduced into the heating generator (200) can be heated, and it is also possible to convert it into steam (water vapor) according to the user's choice. The water or steam heated in the heating generator (200) can be supplied to a mop (150) through a diffuser (137).

[0123] The water tank (120) includes a water supply port. The water supply port is a hole through which water flows into the water tank (120). For example, the water supply port may be formed on the side of the water tank (120).

[0124] The water tank (120) includes a drain. The drain is a hole through which water stored in the water tank (120) is discharged. The water discharged from the drain can flow to a heating generator (200). The drain may be formed on the lower surface of the water tank (120).

[0125] The water tank (120) includes an air hole. The air hole is a hole through which air can be introduced into the water tank (120). When water stored inside the water tank (120) is discharged to the outside, the pressure inside the water tank (120) decreases, and to compensate for the decreased pressure, air can be introduced into the water tank (120) through the air hole. For example, the air hole may be formed at the top of the water tank (120).

[0126]

[0127] The mop module (100) of the present invention may include a water supply unit (130) having a water flow path formed therein to supply water flowing in from a water tank (120) to a mop (150).

[0128] Specifically, the water supply unit (130) may include a water tank connection unit (131) for introducing water from a water tank (120) into the module housing (110), a water inlet pipe (132) for supplying water introduced into the water tank connection unit (131) to a water pump (133), a guide pipe (134) for supplying water from the water pump (133) to a T-shaped connector, and a water supply pipe (135) for supplying water introduced into the connector to a heating generator (200).

[0129] The water tank connection part (131) can operate a valve (not shown) inside the water tank (120) and water can flow.

[0130] The water tank connection part (131) can be connected to the lower side of the upper housing (112), and a part of it can penetrate the upper housing (112) and protrude upward.

[0131] The water tank connection part (131) protruding upward can be inserted into the water tank (120) by penetrating the discharge port of the water tank (120) when the water tank (120) is seated on the upper housing (112).

[0132] The upper housing (112) may be provided with a sealer to prevent water discharged from the water tank (120) from leaking around the water tank connection part (131). For example, the sealer may be formed of a rubber material and may be coupled to the upper housing (112) on the upper side of the upper housing (112).

[0133] A water pump (133) for controlling the discharge of water from the water tank (120) may be installed in the upper housing (112).

[0134] The water pump (133) can provide a flow of water. The water pump (133) may include a first connection port to which a water inlet pipe (132) is connected and a second connection port to which a guide pipe (134) is connected. In this case, with respect to the water pump (133), the first connection port may be an inlet and the second connection port may be an outlet.

[0135] The water pump (133) is a pump that operates by expanding or contracting as the internal valve body operates to connect the first connection port and the second connection port, and since it can be implemented by a known structure, a detailed description is omitted.

[0136] The water supply pipe (135) can connect the connector and the water inlet (212) of the heating generator (200). For example, the water supply pipe (135) may be a pair of pipes branched from the connector.

[0137] Accordingly, water supplied through the water inlet pipe (132) flows into the water pump (133) and then flows into the guide pipe (134). The water flowing into the guide pipe (134) flows into the water supply pipe (135) via a connector. Then, the water flowing into the water supply pipe (135) is supplied to the heating generator (200).

[0138] The heating generator (200) is a device for heating water. The heating generator (200) is placed inside the module housing (110). Specifically, the heating generator (200) is installed on the upper surface of the lower housing (111).

[0139]

[0140] Meanwhile, in the present invention, the heating generator (200) is positioned at an angle. Specifically, based on the state in which the module housing (110) is placed on the bottom surface, the bottom surface of the heating generator (200) may be positioned to form a predetermined angle (α) with respect to the bottom surface.

[0141] The specific structure and effects of the heating generator (200) of the present invention will be described later.

[0142] The diffuser (137) is configured to discharge water from the water tank (120) to the mop (150).

[0143] Specifically, the diffuser (137) includes at least one nozzle and can supply moisture discharged from the heating generator (200) to the mop (150) through the nozzle.

[0144] The diffuser (137) can be accommodated in a space formed inside the module housing (110), and a part of the diffuser (137) can pass through a nozzle hole (not shown) formed in the module housing (110) and be exposed to the outside of the module housing (110).

[0145] The diffuser (137) can be mounted in a pair on the module housing (110) and arranged in a left-right direction. Additionally, the pair of diffusers (137) arranged in a left-right direction can be formed in a shape symmetrical to each other (mirror image).

[0146] The diffuser (137) is connected to the heating generator (200) and can supply moisture flowing through the heating generator (200) to the mop (150).

[0147] The diffuser (137) includes a diffuser body (137a) and a connecting tube (137b).

[0148] The diffuser body (137a) has a diffusion channel formed therein through which moisture can flow, and includes a nozzle through which moisture flowing through the diffusion channel is discharged onto a mop. For example, the diffuser body (137a) may be formed in an arc shape, and a plurality of nozzles may be provided at predetermined intervals. With such a configuration, the diffuser body (137a) can stably supply moisture to a disc-shaped mop (150).

[0149] A connecting pipe (137b) is provided in the diffuser body (137a) and can be coupled with the moisture discharge port (213) of the heating generator (200). The flow path formed inside the connecting pipe (137b) can communicate with the moisture discharge port (213) and the diffusion flow path formed in the diffuser body (137a). With this configuration, moisture discharged from the heating generator (200) can pass through the connecting pipe (137b) and then be discharged to the mop (150) through the diffuser body (137a).

[0150] Then, the water sprayed from the diffuser (137) passes through the water passage hole formed in the rotating cleaner (140) and is supplied to the mop (150). The mop (150) rotates while absorbing the water supplied through the diffuser (137) and wipes the floor.

[0151] As another example, as illustrated in FIG. 11, the diffuser (137') includes a diffuser body (137a') and a connecting pipe (137b'). In this case, the diffuser body (137a') is formed in a ring shape, and a plurality of nozzles may be provided at predetermined intervals. With such a configuration, the diffuser body (137a') can stably supply moisture to a disc-shaped mop (150).

[0152]

[0153] The rotating cleaner (140) can rotate by receiving power from the drive motor (170). For example, the rotating cleaner (140) may be a rotating plate. The rotating cleaner (140) may be formed in the shape of a disc, and a mop (150) may be attached to the lower surface.

[0154] At this time, the disc-shaped rotating cleaner (140) can be positioned parallel to the floor surface while the mop module (100) is placed on the floor surface. Alternatively, the disc-shaped rotating cleaner (140) can be positioned parallel to the bottom surface (111a) of the lower housing (111).

[0155] The rotating cleaning unit (140) can be located, for example, at the rear of the suction port (113a) on the lower side of the module housing (110).

[0156] Therefore, when cleaning by advancing the mop module (100), foreign matter and air on the floor surface are sucked in by the suction port (113a), and then the floor surface can be wiped by the mop (150).

[0157] At least one rotary cleaning unit (140) may be provided on the lower side of the module housing (110). For example, the rotary cleaning unit (140) may include a first rotary cleaning unit (141) connected to a first drive motor (171) and to which a first mop (151) is attached, and a second rotary cleaning unit (142) connected to a second drive motor (172) and to which a second mop (152) is attached.

[0158] Specifically, the rotary cleaning unit (140) may include an outer body in the shape of a circular ring, an inner body located in the central region of the outer body and spaced apart from the inner surface of the outer body, and a plurality of connecting ribs connecting the outer surface of the inner body and the inner surface of the outer body.

[0159] Additionally, the rotating cleaning unit (140) may include a plurality of water passage holes formed along the circumferential direction to supply water discharged through the diffuser (137) to the mop (150).

[0160] Meanwhile, the rotating cleaner (140) may include an attachment means for attaching a mop (150). As an example, the attachment means may be Velcro.

[0161] The rotating cleaning unit (140) can be positioned on the lower side of the lower housing (111). That is, the rotating cleaning unit (140) can be positioned on the outside of the module housing (110).

[0162] Additionally, the rotary cleaner (140) can be connected to a drive motor (170) to receive power. For example, the rotary cleaner (140) can be connected to the drive motor (170) through at least one gear and can be rotated by the operation of the drive motor (170).

[0163] The rotating cleaning unit (140) may include a first rotating cleaning unit (141) and a second rotating cleaning unit (142). For example, with the mop module (100) placed on the floor surface and with respect to the suction port (113a), the first rotating cleaning unit (141) may refer to a rotating cleaning unit (140) positioned on the left side, and the second rotating cleaning unit (142) may refer to a rotating cleaning unit (140) positioned on the right side, but is not limited thereto and the left and right sides may be reversed.

[0164] In this embodiment, the rotation center of the first rotating cleaning unit (141) and the rotation center of the second rotating cleaning unit (142) are spaced apart in the left and right directions.

[0165] The center of rotation of the rotating cleaner (140) may be located further from the front end of the module housing (110) than the central axis that bisects the front-to-back length of the module housing (110). This is to prevent the rotating cleaner (140) from blocking the suction port (113a).

[0166] The distance between the center of rotation of the first rotating cleaning unit (141) and the center of rotation of the second rotating cleaning unit (142) can be formed to be larger than the diameter of the mop (150). This is to reduce mutual friction caused by interference between the first mop (151) and the second mop (152) during the process of rotation, and to prevent the cleaning area from being reduced by the amount of interference.

[0167]

[0168] The mop (150) can wipe the floor surface by rotating.

[0169] The mop (150) can be attached to the lower side of the rotating cleaning unit (140) so as to face the floor surface.

[0170] The mop (150) is formed such that the bottom surface facing the floor has a predetermined area, and the mop (150) is formed in a flat shape. The mop (150) 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 (150) is attached to the lower housing (111), the bottom surface of the mop (150) may be parallel to the floor surface.

[0171] The bottom surface of the mop (150) can generally be circular, and the mop (150) can be formed in a rotationally symmetrical shape overall. Additionally, the mop (150) can be attached to the bottom surface of the rotating cleaning unit (140) and can be coupled to the rotating cleaning unit (140) to rotate together with the rotating cleaning unit (140).

[0172] With the rotating cleaning unit (140) and the mop (150) coupled to the lower side of the module housing (110), a part of the mop (150) protrudes to the outside of the mop module (100), so that it can clean not only the floor surface located below the mop module (100) but also the floor surface located outside the mop module (100).

[0173] For example, the mop (150) can protrude not only to both sides of the wet mop module (100) but also to the rear.

[0174] The mop (150) may include a first mop (151) coupled to a first rotating cleaning unit (141) and a second mop (152) coupled to a second rotating cleaning unit (142). Accordingly, when the first rotating cleaning unit (141) rotates by receiving power from the first driving motor (171), the first mop (151) also rotates together, and when the second rotating cleaning unit (142) rotates by receiving power from the second driving motor (172), the second mop (152) also rotates together.

[0175]

[0176] Meanwhile, in this embodiment, the mop module (100) may further include a light-emitting module (160).

[0177] The light-emitting module (160) can irradiate light onto the front of the mop module (100) to identify foreign substances or microorganisms present in the front of the mop module (100).

[0178] The light-emitting module (160) may be positioned at the front of the module housing (110). For example, the light-emitting module (160) may be positioned at the front of the lower housing (111) and may be positioned in multiple numbers along the left and right directions. At this time, the light-emitting module (160) may be positioned at the rear of the cooling air inlet (117). Through this positioning, the light-emitting module (160) can be cooled by air introduced from the cooling air inlet (117).

[0179] Meanwhile, the light-emitting module (160) may be composed of a light-emitting member and a diffuser plate.

[0180] The light-emitting member can radiate light forward or downward. For example, the light-emitting member may be composed of multiple LEDs. In this case, the light radiated by the light-emitting member may be visible light, and depending on the embodiment, it may be infrared (IR) or ultraviolet (UV). With such a configuration, when the light-emitting member is operated, not only can the presence of foreign substances or microorganisms in front of the mop module (100) be confirmed, but the foreign substances or microorganisms present in front of the mop module (100) can also be sterilized to improve hygiene.

[0181] In addition, the diffuser plate is positioned in front of the light-emitting member and can diffuse the light irradiated from the light-emitting member.

[0182]

[0183] Meanwhile, the mop module (100) may further include a drive motor (170) that provides power to rotate the mop (150) and the rotating cleaner (140).

[0184] Specifically, the drive motor (170) may include a first drive motor (171) that rotates the first rotating cleaner (141) and a second drive motor (172) that rotates the second rotating cleaner (142).

[0185] As such, since the first drive motor (171) and the second drive motor (172) operate individually, there is an advantage that even if either the first drive motor (171) or the second drive motor (172) fails, the rotation of the cleaning unit (140) can be maintained by the other.

[0186] Meanwhile, the first drive motor (171) and the second drive motor (172) may be arranged spaced apart in the left and right directions within the module housing (110). Additionally, the first drive motor (171) and the second drive motor (172) may be located at the rear of the intake port (113a).

[0187] The drive motor (170) may be placed within the module housing (110). For example, the drive motor (170) may be seated on the upper side of the lower housing (111) and covered by the upper housing (112). That is, the drive motor (170) may be located between the lower housing (111) and the upper housing (112).

[0188]

[0189] Meanwhile, the mop module (100) includes a connecting tube (180) that is coupled to the main body (400) or the extension tube (300).

[0190]

[0191] The connecting pipe (180) may include a first connecting pipe connected to the end of the flow path forming part (113), a second connecting pipe rotatably connected to the first connecting pipe, and a guide pipe communicating the inside of the first connecting pipe and the second connecting pipe.

[0192] The first connecting tube is formed in the shape of a tube, with one axial end connected to the end of the flow path forming part (113), and the other axial end rotatably connected to the second connecting tube. At this time, the first connecting tube is formed with a portion of its outer surface cut out, and the cut portion may be positioned to face the second connecting tube and upward. With this configuration, when the mop module (100) is placed on the ground, the angle formed between the second connecting tube and the ground can be changed according to the movement of the user's arm. That is, the first connecting tube and the second connecting tube can function as a kind of joint that can adjust the angle between the mop module (100) and the vacuum cleaner body (400).

[0193] The second connecting tube is formed in the shape of a tube, and one axial end is rotatably connected to the first connecting tube, and the other axial end is detachably connected to the main body of the vacuum cleaner (400) or the extension tube (300) inserted therein.

[0194] Meanwhile, in this embodiment, a module battery housing (500) in which a module battery (600) is accommodated can be coupled to the second connecting pipe.

[0195] Meanwhile, wires may be embedded in the first connector and the second connector, and the wires embedded in the first connector and the second connector may be electrically connected to each other.

[0196] Meanwhile, the guide tube can connect the internal space of the first connecting tube and the internal space of the second connecting tube. The guide tube may have an internal flow path formed therein so that air sucked in from the mop module (100) flows into the extension tube (300) and / or the main body of the vacuum cleaner (400). At this time, the guide tube may deform together with the rotation of the first connecting tube and the second connecting tube. For example, the guide tube may be formed in the shape of a corrugated tube.

[0197]

[0198] Meanwhile, the mop module (100) may include a printed circuit board (190) on which a mop module control unit (700) for controlling the mop module (100) is placed. Current may be applied to the printed circuit board (190), and communication lines may be placed thereon. At this time, the printed circuit board (190) may be cooled by air that flows into the cooling air inlet (117) and is discharged through the cooling air outlet (118).

[0199] Meanwhile, the module housing (110) may further include a first operating unit (191) for controlling the amount of water discharged from the water tank (120). For example, the first operating unit (191) may be located at the rear of the module housing (110).

[0200] The first control unit (191) can be operated by a user, and by operating the first control unit (191), water can be discharged from the water tank (120) or not discharged.

[0201] Alternatively, the amount of water discharged from the water tank (120) can be controlled by the first control unit (191). For example, as the user operates the first control unit (191), the amount of water discharged from the water tank (120) can be set to a first amount per unit time, or a second amount of water, which is greater than the first amount per unit time, can be discharged.

[0202] The first operating part (191) may be provided to pivot in the left-right direction on the module housing (110), or, depending on the embodiment, may be provided to pivot in the up-down direction.

[0203] For example, when the first operating part (191) is in a neutral position, the water discharge amount is 0, and if the left side of the first operating part (191) is pushed so that the first operating part (191) pivots to the left, a first amount of water can be discharged from the water tank (120) per unit time. Then, if the right side of the first operating part (191) is pushed so that the first operating part (191) pivots to the right, a second amount of water can be discharged from the water tank (120) per unit time.

[0204] Meanwhile, the module housing (110) may further include a second control unit (192) for controlling the phase of moisture discharged from the heating generator (200). For example, the second control unit (192) may be located at the rear side of the module housing (110).

[0205] The second control unit (192) can be operated by the user, and by operating the second control unit (192), water can be discharged from the heating generator (200) to the mop (150) or steam (water vapor) can be discharged.

[0206] The second operating part (192) may be provided to be rotatable in the module housing (110). For example, the second operating part (192) may be a rotary knob (dial).

[0207] For example, when the second control unit (192) is rotated to the first position, the water can be discharged to the mop (150) at room temperature without heating the water in the heating generator (200). Additionally, when the second control unit (192) is rotated to the second position different from the first position, the water can be heated in the heating generator (200) and discharged to the mop (150). Furthermore, when the second control unit (192) is rotated to the third position different from the first and second positions, the water can be heated in the heating generator (200) to change the phase of the water into steam (water vapor) and then discharged to the mop (150).

[0208]

[0209] FIG. 9 shows a perspective view illustrating a heating generator in a mop module according to one embodiment of the present invention, FIG. 10 shows an exploded perspective view illustrating a heating generator in a mop module according to one embodiment of the present invention, FIG. 12 shows an assembled perspective view of FIG. 10, FIG. 13 shows a plan view illustrating a heating chamber of a heating generator in a mop module according to one embodiment of the present invention, and FIG. 14 shows a cross-sectional view of a heating generator according to one embodiment of the present invention.

[0210] Referring to FIGS. 3 and FIGS. 9 to 14, a heating generator (200) according to one embodiment of the present invention is described as follows.

[0211] The heating generator (200) can heat water to generate high-temperature water or steam (water vapor). The heating generator (200) can heat water supplied from the water tank (120) and supply it to the mop (150).

[0212] The heating generator (200) is provided in the mop module (100) rather than the vacuum cleaner body (400). This is to prevent cleaning from becoming inconvenient due to the weight and volume of the heating generator during dry cleaning when the heating generator is placed in the vacuum cleaner body.

[0213] The heating generator (200) can be coupled to the upper part of the lower housing (111) (the upper side of the bottom surface (111a)). For example, the heating generator (200) can be coupled to the upper side of the flow path forming part (113). At this time, since the flow path forming part (113) is coupled to the center of the upper side of the lower housing (111), the heating generator (200) can also be placed in the center of the lower housing (111). With this configuration, when the heating generator (200) is operated, a specific location may not be overheated by the heat supplied from the heating generator (200), thus having the effect of preventing damage to the mop module (100). In addition, the overall volume of the mop module (100) can be minimized.

[0214] The heating generator (200) may include a heating chamber (210), a heater (220), a lower cover (230), a sealer (240), an upper cover (250), a lower insulator (260), an upper insulator (270), and a temperature detection unit (290).

[0215] At this time, a heater (220) is positioned on the lower side of the heating chamber (210), a lower insulator (260) is positioned on the lower side of the heater (220), and a lower cover (230) is positioned on the lower side of the lower insulator (260) to cover the lower side of the heating generator (200). Additionally, a sealer (240) is positioned on the upper side of the heating chamber (210), an upper insulator (270) is positioned on the upper side of the sealer (240), and an upper cover (250) is positioned on the upper side of the upper insulator (270) to cover the upper side of the heating generator (200).

[0216] The heating chamber (210) can provide a space in which a water flow path is formed inside and heat is transferred from a heater (220) to heat the water flowing through the path.

[0217] Specifically, the heating chamber (210) includes a chamber body (211), a water inlet (212), a water outlet (213), a partition wall (214), a flow guide wall (215), a flow delay projection (216), and a water reservoir (217).

[0218] The chamber body (211) forms the exterior of the heating chamber (210) and can provide a space where moisture can flow inside. For example, the chamber body (211) can be formed in a shape similar to a rectangular box. For example, the chamber body (211) may have a rectangular plate-shaped bottom surface formed at the bottom, and four side walls (218) formed perpendicularly to the bottom surface and connected. Also, the top of the chamber body (211) may be open. Therefore, the interior of the chamber body (211) can be described as a space enclosed by the bottom surface and the four side walls (218). At this time, the four side walls can be called a front side wall (218a), a rear side wall (218b), and a pair of left and right side walls (218c), respectively, depending on their position.

[0219] Meanwhile, the chamber body (211) may have its internal space separated by a partition wall (214) to be described later. For example, the space located to the left of the partition wall (214) may be called the first chamber, and the space located to the right of the partition wall (214) may be called the second chamber, and it is also possible to reverse the left and right sides of the first chamber and the second chamber.

[0220] Meanwhile, a water inlet (212) and a moisture outlet (213) may be formed in the chamber body (211). Specifically, a water inlet (212) may be formed on the bottom or top surface of the chamber body (211). Additionally, a moisture outlet (213) may be formed on the bottom surface of the chamber body (211). At this time, it is preferable that the water inlet (212) and the moisture outlet (213) be positioned as far apart as possible along the front-rear direction of the mop module (100). This is to ensure sufficient heating time by maximizing the distance the water flowing from the water inlet (212) until it is discharged through the moisture outlet (213).

[0221] For example, the rear end of the chamber body (211) is positioned above the front end of the chamber body (211). That is, the heating generator (200) has a rearward-upward slope. Accordingly, water can be heated as it flows from the rear upper end of the heating generator (200) to the front lower end.

[0222] A water inlet (212) is formed in the chamber body (211), and water can be introduced from the water tank (120). The water inlet (212) may be a hole formed at the inlet end of the chamber body (211).

[0223] Specifically, the water supply pipe (135) of the water supply unit (130) can be connected to the water inlet (212). For example, the water supply pipe (135) is connected to the lower side of the chamber body (211), and the flow path inside the water supply pipe (135) and the water inlet (212) can be in communication with each other. Accordingly, when the water pump (133) is operated, the water stored in the water tank (120) can flow through the water supply pipe (135) and then flow into the chamber body (211) by means of the flow force generated by the water pump (133).

[0224] The moisture discharge port (213) can discharge heated moisture from inside the chamber body (211). The moisture discharge port (213) may be a hole formed at the outlet end of the chamber body (211).

[0225] Specifically, a diffuser (137) may be connected to the moisture outlet (213). For example, the diffuser (137) may be connected to the lower side of the chamber body (211), and the flow path inside the diffuser (137) and the moisture outlet (213) may be in communication with each other. Thus, moisture (water or steam) heated inside the chamber body (211) may pass through the moisture outlet (213), flow into the diffuser (137), and then be supplied to the mop (150).

[0226]

[0227] Meanwhile, the bottom surface of the heating generator is generally positioned parallel to the floor of the installation site. Additionally, a pipe for discharging steam is provided at the top of the heating generator. Therefore, when the heating generator operates to generate steam (water vapor), the system is configured so that the heated steam rises and is discharged to the outside along the pipe.

[0228] However, in the case of a heating generator with this structure, there is a high possibility that a drain will occur as the steam comes into contact with the inner wall or piping of the heating generator during the rising process. Therefore, it is necessary to reduce heat loss that may occur during the steam flow process and, even if a drain occurs, to reheat it and supply it to the rag.

[0229] To solve this, the heating generator (200) according to an embodiment of the present invention is positioned at a predetermined angle with respect to the bottom surface.

[0230] Specifically, when the mop module (100) is placed on the floor surface (a state in which the mop (150) is placed on the floor surface to wipe the floor surface), the bottom surface of the chamber body (211) can be positioned at an angle (α) to the floor surface.

[0231] The bottom surface (111a) of the lower housing (111) to which the rotating cleaner (140) and mop (150) are coupled to the lower side and the bottom surface of the chamber body (211) can be arranged at an angle (α). That is, the virtual extension surface of the bottom surface of the chamber body (211) can intersect with the virtual extension surface of the bottom surface (111a) of the lower housing (111).

[0232] Additionally, the height from the bottom surface to the water inlet (212) may be higher than the height from the bottom surface to the water outlet (213). Also, the distance from the bottom surface (111a) of the lower housing (111) to the water inlet (212) may be greater than the distance from the bottom surface (111a) to the water outlet (213).

[0233] Additionally, the shortest distance from the disc-shaped rotating cleaner (140) to the water inlet (212) may be greater than the shortest distance from the rotating cleaner (140) to the water outlet (213). Furthermore, the bottom surface of the chamber body (211) may be inclined at a predetermined angle (α) with respect to the virtual extension surface of the disc-shaped rotating cleaner (140). That is, the virtual extension line of the bottom surface of the chamber body (211) may intersect with the virtual extension surface of the rotating cleaner (140).

[0234] With this configuration, even if the water introduced into the water inlet (212) is heated and undergoes upward convection, it can be heated while flowing from the upper to the lower part of the chamber body (211) by gravity.

[0235] Furthermore, even if the water heated inside the chamber body (211) undergoes a phase change into steam and rises, it is not discharged to the top of the chamber body (211) but remains inside the chamber body (211) and can be further heated.

[0236] In addition, the drain generated inside the heating generator (200) is not discharged to the outside and can be continuously heated.

[0237]

[0238] The partition wall (214) may be formed to protrude upward from the bottom surface of the chamber body (211) along the front-rear direction of the mop module (100). For example, the partition wall (214) may be a wall extending to the rear from a side wall (front side wall (218a)) positioned at the front of the chamber body (211). The partition wall (214) may be connected to a flow guide wall (215) to be described later. Meanwhile, a temperature detection unit (290) may be positioned at the rear side of the point where the partition wall (214) and the flow guide wall (215) are connected.

[0239] With this configuration, the partition wall (214) can separate the internal space of the chamber body (211) into left and right sides. That is, the internal space of the chamber body (211) can be separated into a first chamber and a second chamber with the partition wall (214) and the temperature detection unit (290) as boundaries.

[0240] Therefore, the moisture flowing inside the first chamber and the moisture flowing inside the second chamber can be discharged independently without mixing with each other. Thus, even if the heating chamber (210) shakes according to the user's operation, the pair of diffusers (137) can discharge moisture uniformly.

[0241]

[0242] A flow guide wall (215) is formed protruding inside the chamber body (211) and can be formed at least one along the left and right directions.

[0243] Specifically, the flow guide wall (215) is formed to protrude vertically from the bottom surface of the chamber body (211). At this time, with respect to the bottom surface of the chamber body (211), the flow guide wall (215) may be formed to protrude along the left-right direction of the mop module (100) and may be formed to be inclined toward the front at a predetermined angle. Alternatively, with respect to the direction of gravity, the flow guide wall (215) may be formed to protrude along the left-right direction of the mop module (100) and may be formed to be inclined toward the downward at a predetermined angle. In addition, with respect to the direction in which water flows inside the heating chamber (210), the spacing between the plurality of flow guide walls (215) may be formed to gradually widen from the inlet side to the outlet side.

[0244] And, the flow guide wall (215) can be connected to the left and right side walls (218c) or partition wall (214) of the chamber body (211).

[0245] That is, one end of the flow guide wall (215) is connected to the flow delay projection (216), and the other end of the flow guide wall (215) can be connected to the side wall (218) or partition wall (214) of the chamber body (211). At this time, one end of the flow guide wall (215) can be positioned closer to the bottom surface (lower side in the direction of gravity) than the other end.

[0246] With this configuration, a channel through which water can flow can be formed between the partition wall (214) and the flow guide wall (215), or between the side wall of the chamber body (211) and the flow guide wall (215).

[0247] Meanwhile, in this embodiment, a plurality of flow guide walls (215) may be formed. At this time, the plurality of flow guide walls (215) may be alternately connected to the side walls and partition walls (214) of the chamber body (211).

[0248] With this configuration, the flow path inside the chamber body (211) can be formed in a zigzag shape. As a result, the flow path of the water flowing inside the chamber body (211) can be increased, and sufficient time can be secured to heat the water inside the chamber body (211). In addition, it has the effect of increasing the surface area for transferring heat to the water flowing inside the chamber body (211). Furthermore, even if the heating generator (200) shakes, it has the effect of maintaining the direction of water flow to maintain the supply amount of water or steam.

[0249]

[0250] The flow delay projection (216) may be formed protruding from one end of the flow guide wall (215). Specifically, it may be formed protruding backward from one end of the flow guide wall (215).

[0251] Meanwhile, in this embodiment, the rear (or upper) end of the flow delay projection (216) may be positioned further from the bottom surface (upward in the direction of gravity) than the other end of the flow guide wall (215).

[0252] With this configuration, water flowing along the flow guide wall (215) comes into contact with the flow delay protrusion (216), and the flow velocity of the water can be reduced. Therefore, sufficient time can be secured for the water introduced into the heating generator (200) to be heated to a target temperature.

[0253]

[0254] The water reservoir (217) is formed as a concave depression on the bottom surface of the chamber body (211). The water reservoir (217) may be positioned at the front of the bottom surface of the chamber body (211). Additionally, the water reservoir (217) may receive water that has flowed along the flow guide wall (215) closer to the bottom surface (lower side in the direction of gravity) on the bottom surface of the chamber body (211). Furthermore, the lowest part of the water reservoir (217) may be positioned closer to the bottom surface (lower side in the direction of gravity) than the water discharge port (213).

[0255] With this configuration, water that flows inside the chamber body (211) but does not undergo a phase change into steam is collected in the water reservoir (217) and can be continuously heated. Therefore, even if the heating generator (200) shakes, it is possible to prevent water that has not been sufficiently heated from suddenly being discharged through the water discharge port (213).

[0256]

[0257] Meanwhile, in the present invention, a pair of temperature detection unit receiving walls (219) may be formed in the chamber body (211) to accommodate a temperature detection unit (290). The temperature detection unit receiving walls (219) may be formed protruding inside the chamber body (211) and may include a connecting wall connecting a pair of side walls and the front end of the pair of side walls. On the other hand, the rear end may be formed in an open shape so that the temperature detection unit (290) can be inserted.

[0258] Accordingly, the temperature detection unit (290) can be inserted inside the temperature detection unit receiving wall (219) and placed inside the chamber body (211).

[0259] At this time, the length of the temperature detection unit receiving wall (219) can be changed according to the number and arrangement of the heaters (220), and the temperature detection unit (290) can be positioned so that at least a portion of each of the plurality of heaters (220) faces it. Accordingly, the temperature detection unit (290) has the effect of precisely detecting the temperature inside the chamber body (211) according to the operation of each heater (220).

[0260]

[0261] The heater (220) can generate heat. The heater (220) is a device capable of converting electrical energy into thermal energy, and since it can be implemented by a known structure, a detailed description will be omitted.

[0262] A heater (220) is positioned below the heating chamber (210) and can supply heat to the heating chamber (210). Specifically, the heater (220) can be in contact with the bottom surface of the heating chamber (210). Therefore, when heat is generated from the heater (220), the heating chamber (210) in contact with the heater (220) can be heated by conduction. Accordingly, the heater (220) can heat the water flowing inside the heating chamber (210) by receiving power from the main battery (410) and / or module battery (600) provided in the vacuum cleaner body (400).

[0263] Meanwhile, the heater (220) can adjust the temperature of the water according to the user's input. In addition, the heater (220) can change the phase of the water into steam (water vapor) according to the user's input.

[0264] Meanwhile, in this embodiment, a plurality of heaters (220) may be provided. For example, the heater (220) may include a first heater (221) formed along the left-right direction of the mop module (100) and a second heater (222) formed parallel to the first heater (221). For another example, the heater (220) may include a first heater (221) formed along the front-back direction of the mop module (100) and a second heater (222) formed parallel to the first heater (221).

[0265]

[0266] Meanwhile, the vacuum cleaner (1) of the present invention is equipped with a plurality of power sources, and the heater (220) can receive power from a plurality of power sources. Each of the plurality of power sources is independently connected to the heater (220). Accordingly, only one of the plurality of power sources can supply power to the heater (220), or all of the plurality of power sources can supply power to the heater (220).

[0267] Multiple heaters (220) may receive power from multiple power sources. Multiple heaters (220) are independently connected to multiple power sources. The power sources may include a first power source and a second power source. For example, the first power source may be a main battery (410) provided in the vacuum cleaner body (400), and the second power source may be a module battery (600) connected to the mop module (100).

[0268] However, in this embodiment, the number of power sources and heaters (220) is given as an example of two, but is not limited thereto and may include cases where three or more are provided.

[0269] At this time, the first power source (410) can supply power to the first heater (221), and the second power source (600) can supply power to the second heater (222).

[0270] The first power source (410) is connected to the mop module control unit (700) through the main body control unit (420) provided in the main body (400), and the second power source (600) can be connected to the mop module control unit (700).

[0271] The mop module control unit (700) can control whether to output the first power output from the first power source (410) to the first heater (221) and whether to output the second power output from the second power source (600) to the second heater (222).

[0272] With this configuration, the vacuum cleaner (1) according to the present invention is equipped with a plurality of power sources, so that the total operating time of the heater (220) during wet mop cleaning can be extended by operating only the first heater (221) and then operating only the second heater (222), and the usage time of the vacuum cleaner (1) can be extended.

[0273] In addition, power can be supplied to the heater (220) using only some of the multiple power sources, so the user can disconnect some of the multiple power sources depending on the cleaning environment when mopping. Accordingly, the user can reduce the usage time of the vacuum cleaner (1) and lighten the weight of the vacuum cleaner, and can use the first power source (410) or the second power source (600) interchangeably. In addition, if necessary, the user can install all of the multiple batteries to extend the usage time of the vacuum cleaner.

[0274] A plurality of heaters (220) are positioned at the bottom of the heating chamber (210). Specifically, the plurality of heaters (220) are positioned to be in contact with the lower surface of the chamber body (211) and supply heat to the heating chamber (210) by conduction.

[0275] The heater (220) may be configured to include a plurality of heating wires.

[0276] For example, as illustrated in FIG. 15, each of the plurality of heaters (220) may consist of a separate body of the heater (220) and a heating wire provided inside the body. For example, the first heater (221) may have a heating wire (221a) provided inside the first heater body, and the second heater (222) may have a heating wire (222a) provided inside the second heater body.

[0277] At this time, the first heater (221) may be positioned higher than the second heater (222) from the ground. That is, the first heater (221) is positioned adjacent to the water inlet (212), and the second heater (222) is positioned adjacent to the water outlet (213).

[0278] Accordingly, water introduced through the water inlet (212) can flow through the upper part of the heating chamber (210) adjacent to the first heater (221), then flow through the lower part of the heating chamber adjacent to the second heater (222), and be discharged through the water outlet (213).

[0279] At this time, the first heater (221) and the second heater (222) may be installed individually. In this case, heat may be transferred between the first heater (221) and the second heater (222) by convection. Meanwhile, the first heater (221) and the second heater (222) can each be replaced.

[0280] Furthermore, since the internal temperature of each heater body rises or falls evenly, it prevents damage caused by localized heating and offers the advantage of high durability. Additionally, it has the advantages of a low defect rate and stable output.

[0281] As another example, as illustrated in FIG. 16, the heater (220) may have a plurality of heating wires arranged within a single body. For example, the heater (220) may have a heating wire (221a) of the first heater (221) and a heating wire (222a) of the second heater (222) arranged within a single heater body. At this time, the heating wire (221a) of the first heater (221) and the heating wire (222a) of the second heater (222) may be spaced apart at a predetermined distance along the front-rear direction. Alternatively, a separating wall may be formed between the heating wire (221a) of the first heater (221) and the heating wire (222a) of the second heater (222) to maintain a distance between the heating wire (221a) of the first heater (221) and the heating wire (222a) of the second heater (222).

[0282] At this time, the first heater (221) and the second heater (222) can be installed at once. In this case, the heat transfer rate between the first heater (221) and the second heater (222) is high. Therefore, in the integrated heater body, even if only the first heater (221) generates heat, the temperature of the part where the second heater (222) is placed can also rise through conduction.

[0283] In addition, since the first heater (221) and the second heater (222) are placed inside the integrated heater body, the number of parts is reduced, the structure is simplified, and the process is reduced, which has the advantage of saving manufacturing costs.

[0284] As another example, as illustrated in FIG. 17, the heater (220) may have a plurality of heating wires arranged within a single body, and the plurality of heating wires may be arranged such that each of them is bent multiple times and interlocked with one another. For example, the heating wire (221a) of the first heater may be formed by bending multiple times at regular intervals, and the heating wire (222a) of the second heater may be formed by bending multiple times, and at least a portion of the heating wire (222a) of the second heater may be configured to be placed between the heating wire (221a) of the first heater.

[0285] Therefore, even if only one of the first heater (221) and the second heater (222) is operated, heat is supplied evenly to the entire chamber body (211), and heat can be supplied stably to the moisture so that there is no section where the temperature of the moisture flowing through the chamber body (211) drops in the middle. Accordingly, the temperature of the moisture can be maintained stably.

[0286] Meanwhile, the body of the heater (220) is formed of a material with high conductivity and thermal conductivity, and has a shape and structure with high conductivity and thermal conductivity. For example, the first heater body, the second heater body, and the integrated body may be formed in the shape of a cuboid where the length in the left-right direction is greater than the width in the front-back direction.

[0287] Additionally, the heater (220) may be a ceramic heater, and the heating wire (221a) of the first heater (221) and the heating wire (222a) of the second heater (222) may be formed of a ceramic material.

[0288] Meanwhile, although not illustrated, a plurality of heaters (220) may be provided with a terminal coupling portion on one side that is connected to each heater. The terminal coupling portion may be connected to a mop module control unit (700) and connected to a plurality of power sources. For example, the mop module control unit (700) may be independently connected to a first power source (410) and a second power source (600). At this time, the mop module control unit (700) may connect the first power source (410) to the first heater (221) and connect the second power source (600) to the second heater (222).

[0289] Accordingly, when the heating generator (200) is operated, it is possible to supply power to only one of the multiple heaters (220) or to supply power to all of the multiple heaters (220). For example, power may be supplied to only one of the first heater (221) and the second heater (222), or power may be supplied to both the first heater (221) and the second heater (222).

[0290] Accordingly, the heater (220) of the present invention may have a plurality of modes capable of operating a plurality of heaters (220).

[0291] For example, the heater (220) of the present invention may operate in a first mode in which power is supplied to both the first heater (221) and the second heater (222). The first mode may be applied according to the user's choice. In the first mode, moisture (water or steam) may be heated first by receiving heat from the first heater (221), and then heated second by receiving heat from the second heater (222). In this case, since sufficient heating of the moisture is possible, high-temperature water or steam can be discharged onto the mop (150) to wipe the floor surface.

[0292] Additionally, the heater (220) of the present invention may operate in a second mode in which power is supplied only to the first heater (221). The second mode may be applied when the user selects it or when the mop module control unit (700) detects that the second power source (600) is not installed. In the second mode, moisture (water or steam) may be heated by receiving heat from the first heater (221) immediately after it is introduced into the heating chamber (210). In this case, since only the first power source (410) supplying power to the first heater (221) is required, the mop module (100) can be lightly operated without the second power source (600) installed (or with the second power source (600) disconnected).

[0293] Additionally, the heater (220) of the present invention may operate in a third mode in which power is supplied only to the second heater (222). The third mode may be applied when selected by the user or when the charge amount of the first power source (410) is lower than a preset reference value. In the third mode, moisture (water or steam) may be heated by receiving heat from the second heater (222) before being discharged from the heating chamber (210). In this case, the second heater (222) may receive power from the second power source (600), and other components such as the vacuum cleaner body (400), water pump (133), and drive motor (170) may receive power from the first power source (410).

[0294] As such, in the present invention, the first heater (221) and the second heater (222) can be selectively driven to adjust the usage time limited by the battery capacity. In addition, various modes are provided according to changes in power consumption or power source, and the temperature level of the mop module (100) can be effectively changed, and there is an advantage of easy power distribution.

[0295]

[0296] The lower cover (230) is positioned below the heater (220) and the lower insulator (260) and can cover the heater (220) and the lower insulator (260). For example, the lower cover (230) may be formed in a flat plate shape, but may be formed in a shape that can wrap around the heater (220) and the lower insulator (260). The lower cover (230) may be formed of a material capable of blocking heat generated from the heater (220).

[0297] With this configuration, energy efficiency can be improved by preventing heat generated from the heater (220) from escaping to the outside of the heating generator (200). Additionally, it is possible to prevent damage to the components housed inside the module housing (110) caused by the heat generated from the heater (220).

[0298] A sealer (240) is positioned above the heating chamber (210) and can seal the upper side of the heating chamber (210). Specifically, the sealer (240) can seal the open upper side of the chamber body (211). The sealer (240) can be formed of a material capable of blocking the passage of moisture. With this configuration, even if water vapor generated inside the heating chamber (210) rises, it can be blocked by the sealer (240) and prevent leakage to the outside.

[0299] The upper cover (250) is positioned above the sealer (240) and the upper insulator (270) and can cover the sealer (240) and the upper insulator (270). For example, the upper cover (250) may be formed in a flat plate shape, but may be formed in a shape that can wrap around the sealer (240) and the upper insulator (270). The upper cover (250) may be formed of a material capable of blocking heat transmitted through the sealer (240).

[0300] With this configuration, energy efficiency can be improved by preventing heat generated from the heater (220) from escaping to the outside of the heating generator (200). Additionally, it is possible to prevent damage to the components housed inside the module housing (110) caused by the heat generated from the heater (220).

[0301] The lower insulator (260) is positioned between the heater (220) and the lower cover (230) and can block heat transferred from the heater (220). The lower insulator (260) may be formed to have a larger surface area than the heater (220). For example, the lower insulator (260) may be formed in the shape of a flat plate and may be formed of a material capable of blocking heat transfer.

[0302] With this configuration, energy efficiency can be improved by preventing heat generated from the heater (220) from escaping to the outside of the heating generator (200). Additionally, damage to components housed inside the module housing (110) can be prevented by the heat generated from the heater (220). In particular, in this embodiment, the heat generated from the heater (220) is double-blocked by the lower insulator (260) and the lower cover (230), thereby maximizing the effects of improving energy efficiency and preventing component damage.

[0303] The upper insulator (270) is positioned above the sealer (240) and can block heat transferred from the heating chamber (210). The upper insulator (270) may be formed to have a larger surface area than the sealer (240). For example, the upper insulator (270) may be formed in the shape of a flat plate and may be formed of a material capable of blocking heat transfer.

[0304] With this configuration, energy efficiency can be improved by preventing heat from the heating chamber (210), heated by the heater (220), from escaping to the outside of the heating generator (200). Additionally, it is possible to prevent heat from the heating chamber (210) from escaping to the outside of the heating generator (200) and damaging the components housed inside the module housing (110). In particular, in this embodiment, the heat from the heating chamber (210) is double-blocked by the upper insulator (270) and the upper cover (250), thereby maximizing the effects of improving energy efficiency and preventing component damage.

[0305] The temperature detection unit (290) can measure the temperature of the heating generator (200).

[0306] The temperature detection unit (290) may be positioned on the side of the heating chamber (210). Specifically, the temperature detection unit (290) may be positioned on the outer surface of the side wall (218) of the heating chamber (210). For example, the temperature detection unit (290) may be positioned on the outer surface of the rear side wall (218b).

[0307] The temperature detection unit (290) can measure the temperature of the heating chamber (210). For example, the temperature detection unit (290) may be a thermistor. In this case, the temperature detection unit (290) can transmit information about the measured temperature of the heating chamber (210) to the mop module control unit (700).

[0308] The temperature detection unit (290) can be positioned along the front-rear direction so that temperature detection is easy regardless of which mode from the first to the third mode is operated. Specifically, the temperature detection unit (290) can be positioned along the temperature detection unit receiving wall (219). That is, the temperature detection unit (290) can be positioned between the left chamber and the right chamber.

[0309] At this time, the temperature detection unit (290) may be positioned to face each of the plurality of heaters (220). For example, at least a portion of the temperature detection unit (290) may be positioned to face the first heater (221), and at least another portion may be positioned to face the second heater (222).

[0310] The heating generator (200) can control the temperature of the water by using a temperature detection unit (290) to supply hot water or room temperature water of a predetermined temperature to the mop.

[0311]

[0312] Meanwhile, referring to FIG. 1, the vacuum cleaner (1) of the present invention may include an extension tube (300).

[0313] The extension tube (300) can be combined with the vacuum cleaner body (400) and the mop module (100).

[0314] For example, the extension tube (300) may be formed in a long cylindrical shape. Thus, the internal space of the extension tube (300) may be in communication with the internal space of the mop module (100). Additionally, the extension tube (300) may be in communication with the suction path formed in the suction part of the vacuum cleaner body (400).

[0315] When suction power is generated through a suction motor (not shown), suction power can be provided to the mop module (100) through the suction part and the extension tube (300). Accordingly, external dust and air can be introduced into the vacuum cleaner body (400) through the mop module (100) and the extension tube (300). Additionally, dust and air introduced through the mop module (100) can be introduced into the vacuum cleaner body (400) after passing through the extension tube (300).

[0316] Meanwhile, an electrical wire may be embedded in the extension tube (300). Accordingly, the vacuum cleaner body (400) and the mop module (100) can be electrically connected through the extension tube (300).

[0317]

[0318] Meanwhile, referring to FIG. 1, the vacuum cleaner (1) of the present invention may include a vacuum cleaner body (400).

[0319] The vacuum cleaner body (400) may be configured to include a suction motor, a dust bin, and a main battery (410). The vacuum cleaner body (400) may operate the suction motor by receiving power from the main battery (410), and may generate suction power by the operation of the suction motor.

[0320] A suction channel is formed in the main body (400) of the vacuum cleaner so that air and dust introduced from the mop module (100) can flow through it.

[0321] In addition, the vacuum cleaner body (400) may be equipped with at least one cyclone section that separates dust sucked into the interior by applying the principle of a dust collector utilizing centrifugal force. Accordingly, the air introduced through the suction path may separate dust while flowing in a spiral motion.

[0322] And the vacuum cleaner body (400) is equipped with a dust bin so that it can store dust separated from the air sucked in through the cyclone flow.

[0323] And the main battery (410) can supply power to the mop module (100). At this time, the main battery (410) can supply power to the drive motor (170) of the mop module (100). And the main battery (410) can supply power to the water pump (133) of the mop module (100).

[0324] Meanwhile, the main battery (410) may supply power to the drive motor (170) and the water pump (133), but may not supply power to the heating generator (200). Alternatively, the main battery (410) may supply power to the drive motor (170), the water pump (133), and the heating generator (200).

[0325] Additionally, the vacuum cleaner body (400) may be equipped with a body control unit (420). The body control unit (420) may be connected to the main battery (410) to receive power. Additionally, the body control unit (420) may be connected to the mop module control unit (700) to send power and signals.

[0326] The main body control unit (420) can control parts provided in the vacuum cleaner main body (400), including a suction motor.

[0327] And the vacuum cleaner body (400) is equipped with an input section so that the user can set whether to supply power and the strength of air suction, as well as the strength of rotation of the mop, the amount of water supplied, whether to heat water, and whether to supply steam.

[0328]

[0329] Referring to FIGS. 1 and FIGS. 2, the vacuum cleaner (1) of the present invention may include a module battery housing (500).

[0330] The module battery housing (500) is coupled to the mop module (100) or the extension tube (300), and the module battery (600) can be detachably coupled. For example, the module battery housing (500) is coupled to the connecting tube (180) of the mop module (100) and can detachably accommodate the module battery (600) inside.

[0331] The module battery housing (500) can electrically connect the module battery (600) to the heating generator (200). With this configuration, the electrical energy of the module battery (600) can be supplied to the heating generator (200) which requires a high power supply.

[0332] Alternatively, the module battery housing (500) may also be connected in series with the battery (not shown) provided in the vacuum cleaner body (400) and the module battery (600). With such a configuration, power can be supplied stably when a high power supply is required, such as when the heating generator (200) is operating.

[0333] Alternatively, the module battery housing (500) can also be configured to connect the main battery (410) and the module battery (600) in parallel, which are provided in the vacuum cleaner body (400). With such a configuration, the usage time of the vacuum cleaner (1) can be extended.

[0334]

[0335] Referring to FIGS. 1 and FIGS. 2, the vacuum cleaner (1) of the present invention may include a module battery (600).

[0336] The module battery (600) can store electrical energy internally. For example, the module battery (600) can be a secondary battery.

[0337] The module battery (600) can supply power to the mop module (100). Specifically, the module battery (600) can supply power to the heating generator (200). At this time, the module battery (600) and the heating generator (200) can be electrically connected, and a mop module control unit (700) can be connected between the module battery (600) and the heating generator (200). That is, the power supplied from the module battery (600) can pass through the mop module control unit (700) and be supplied to the heater (220) of the heating generator (200).

[0338]

[0339] In this embodiment, the power supply relationship between the module battery (600) and the main battery (410) is described as follows.

[0340] In this embodiment, when the module battery (600) is not installed in the vacuum cleaner (1), the main battery (410) can supply power to the vacuum cleaner body (400) and the mop module (100).

[0341] Meanwhile, when a module battery (600) is installed in the vacuum cleaner (1), the main battery (410) supplies power to the vacuum cleaner body (400) and the mop module (100), but may not supply power to the heating generator (200).

[0342] That is, when the module battery (600) is installed in the vacuum cleaner (1), the main battery (410) supplies power to the drive motor (170) and water pump (133) of the mop module (100), and the module battery (600) can supply power to the heating generator (200).

[0343] Meanwhile, when the temperature of the heating chamber (210) is above the reference temperature (Tr) while the module battery (600) is installed in the vacuum cleaner (1), the connection between the module battery (600) and the heater (220) is cut off by the mop module control unit (700). Accordingly, the power supplied to the heater (220) is cut off. On the other hand, the drive motor (170) and the water pump (133) can continue to receive power from the main battery (410).

[0344] With this configuration, when the heating generator (200) overheats, only the function of heating water is stopped, while the function of supplying water to the mop and the function of rotating the mop can be maintained. Therefore, the cleaning performance of the wet mop module (100) can be maintained by supplying already heated water to the mop.

[0345]

[0346] FIG. 18 illustrates a diagram for explaining the control configuration of a cleaning module according to one embodiment of the present invention.

[0347] Referring to FIGS. 1 to 18, the control configuration of the mop module (100) according to an embodiment of the present invention is described as follows.

[0348] A mop module (100) according to an embodiment of the present invention includes a mop module control unit (700).

[0349] The mop module control unit (700) may include a memory (not shown) and a timer (not shown). Pre-set information may be stored in the memory (not shown). The timer (not shown) may measure time.

[0350] Although not shown, the mop module control unit (700) can receive a control signal input through the vacuum cleaner body (400), the mop module (100), or an external terminal (not shown). For example, the mop module control unit (700) can be connected to the vacuum cleaner body (400), the mop module (100), or an external terminal (not shown) via wired or wireless communication.

[0351] The mop module control unit (700) can control the components included in the mop module (100).

[0352] The mop module control unit (700) may be signal-connected to the first control unit (191) and the second control unit (192). For example, the mop module control unit (700) may be electrically connected to the first control unit (191) and the second control unit (192) and may transmit and receive electrical signals. With such a configuration, the mop module (100) may receive a control signal based on user input from the first control unit (191) and / or the second control unit (192) and operate according to the received control signal.

[0353] The mop module control unit (700) can be signal-connected to the temperature detection unit (290). The temperature detection unit (290) can measure the temperature of the heating generator (200) and transmit information about the temperature of the heating generator (200) to the mop module control unit (700).

[0354] The mop module control unit (700) can receive power from the main battery (410).

[0355] The mop module control unit (700) can receive power from the module battery (600).

[0356] The mop module control unit (700) can control the water pump (133). The mop module control unit (700) can control the amount of water supplied from the water tank (120) to the mop (150) according to a control signal input from the first operating unit (191). For example, the mop module control unit (700) can control the operating time of the water pump (133) according to a control signal input from the first operating unit (191).

[0357] The mop module control unit (700) can control the heater (220). The mop module control unit (700) can control the temperature and phase of the moisture supplied to the mop (150) according to a control signal input from the second control unit (192). For example, the mop module control unit (700) can control the operating time of the heater (220) and the amount of power applied to the heater (220) according to a control signal input from the second control unit (192). In addition, the mop module control unit (700) can change the operating time of the heater (220) and the amount of power applied to the heater (220) if the temperature of the heating generator (200) measured by the temperature detection unit (290) differs from a preset target temperature.

[0358] With such a configuration, according to the present invention, the temperature or phase of the water introduced into the heating generator (200) can be maintained, and energy efficiency can be increased.

[0359] Additionally, when the heating generator (200) is operated, the mop module control unit (700) can control the driver of the first heater (221) and the driver of the second heater (222) to drive the first heater (221) and the second heater (222) independently. Additionally, the mop module control unit (700) can independently vary the power supplied to the first heater (221) and the second heater (222).

[0360] Additionally, the mop module control unit (700) is connected to the main body control unit (420) through a connection terminal, and the main body control unit (420) can be connected to the first power source (410) through the connection terminal. Additionally, the mop module control unit (700) can be connected to the second power source (600) through the connection terminal.

[0361] Additionally, the mop module control unit (700) may have a first switch connected to the driver of the first heater (221) and a second switch connected to the driver of the second heater (222). The first switch may be connected to the first power supply (410), and the second switch may be connected to the second power supply (600).

[0362] Accordingly, the mop module control unit (700) can operate a plurality of heaters (220) according to the plurality of modes above.

[0363] Therefore, when power is supplied to both the first heater (221) and the second heater (222), the heater (220) can operate at maximum output, and when power supply to either heater (220) is cut off, it can operate at a relatively low output.

[0364] Accordingly, the user can separate some of the multiple power sources to use them at low output and supply only some power to the heater (220). In this case, the usage time of the vacuum cleaner (1) can be reduced, or the temperature of the heater (220) can be lowered and the temperature of the hot water supplied to the mop module (100) can be lowered. At this time, if the temperature of the heater (220) is lowered, the usage time of the vacuum cleaner (1) can be increased.

[0365] That is, in the present invention, it is possible to change the power supplied according to the cleaning situation, adjust the amount of steam or hot water generated, effectively change the temperature level of the heater (220), and perform multiple operation modes.

[0366] In addition, the required output of the first heater (221) and the second heater (222) is lowered, and components and parts suitable for the output level can be replaced with relatively lower specifications, which has the advantage of enabling cost reduction and energy saving.

[0367] In addition, the mop module control unit (700) can receive information from the temperature detection unit (290) to control the temperature or detect and prevent overheating.

[0368] Additionally, according to an embodiment, the mop module control unit (700) can control the light-emitting module (160). The mop module control unit (700) can control the light-emitting module (160) on / off according to the user's control input. Additionally, the mop module control unit (700) can also control the amount of light of the light-emitting module (160) according to the user's control input.

[0369] Additionally, according to an embodiment, the mop module control unit (700) can control the drive motor (170). The mop module control unit (700) can control the rotational speed (rpm) of the drive motor (170) according to the user's control input.

It is evident that modifications or improvements to the present invention are possible by those skilled in the art within the technical scope of the invention.

[0372] All simple variations or modifications of the present invention fall within the scope of the present invention, and the specific scope of protection of the present invention will be clarified by the appended claims.
