Description

Vacuum cleaner

The present invention relates to a vacuum cleaner, and more particularly, to a vacuum cleaner including a detachably arranged cleaning module configured to suck dust or debris from a target cleaning area and clean it by discharging water to the mop. Wipe the targeted cleaning area.

A vacuum cleaner refers to a device that cleans a target cleaning area by sucking in dust or debris or wiping the target cleaning area.

Vacuum cleaners may be classified into: manual cleaners, which are directly moved by a user to perform cleaning operations; and automatic cleaners, which perform cleaning operations while automatically traveling.

Handheld vacuum cleaners (handheld vacuum cleaners) are designed for maximum portability and are lightweight. However, due to the short length of the handheld vacuum cleaner, the cleaning area may be limited. Accordingly, hand-held vacuum cleaners are used to clean local places such as tables, sofas, or the interior of vehicles.

The user can use the stick cleaner while standing, and thus can perform cleaning operations without bending his/her waist. Therefore, the stick cleaner facilitates the user to clean a wide area while moving in the area. Hand-held vacuums can be used to clean narrow spaces, while stick vacuums can be used to clean wide spaces and high places that cannot be reached by the user's hands. Recently, a modular stick cleaner is provided so that the type of cleaner is actively changed and used to clean various places.

The method of cleaning the floor is roughly divided into dry cleaning method and wet cleaning method. The dry cleaning method refers to the method of wiping or vacuuming, and the vacuum cleaner in the related art adopts the dry cleaning method. The wet cleaning method refers to the method of wiping dust with a wet mop for cleaning operations. As another wet cleaning method, there is a method of disinfecting and cleaning floors by generating and spraying high-temperature steam.

Recently, various cleaning methods have been proposed to cope with the use of various building materials. In the related art, since the floor is mainly made of wood material, the wet cleaning method cannot be performed, so only the dry cleaning method can be performed. However, recently, floors are made of various materials such as steel plates or marble, and thus wet cleaning can be performed.

In the related art, a cleaner dedicated for dry cleaning is used to perform a dry cleaning method, and a cleaner dedicated for wet cleaning is used to perform a wet cleaning method. However, since the user needs to purchase two types of vacuum cleaners to clean various types of floors, inconvenience is caused to the user. In order to solve the above problems, research has been conducted on a vacuum cleaner including a single main body, a dry cleaning module and a wet cleaning module, and the dry cleaning module is mounted on the main body to perform a dry cleaning method and the wet cleaning module is mounted on the main body for wet cleaning.

The wet cleaning module includes: a water container configured to store water; a heater configured to generate steam by heating the water; and a mop configured to wipe the floor by receiving the water or steam. Each component can be configured as a single component so that each component can be easily replaced. For example, when the dry cleaning module is mounted on the main body in a state where the water container or the heater is disposed on the main body, unnecessary components may hinder cleaning operations. Therefore, the water container or the heater can be provided on the wet cleaning module instead of being mounted on the main body to ensure easy cleaning, easy module replacement or space utilization.

Korean Utility Model Registration No. KR0489070Y1 discloses a wet mop cleaner in which a main battery is disposed in a cleaning module, and an auxiliary battery is detachably coupled to an extension tube.

However, a wet mop vacuum cleaner cannot pick up dust and requires most of the power to turn the mop, and the coupled auxiliary battery is only used to increase the use time of the vacuum cleaner.

In addition, when debris is attached to the floor, even if a vacuum cleaner configured to wipe the floor surface by spinning the mop wipes the floor by spinning the mop filled with water, the debris may remain on the floor.

Furthermore, in the case where microorganisms and the like proliferate on the floor, even if a vacuum cleaner wipes the floor by rotating a mop filled with water, there is a limit in completely eliminating the microorganisms.

In order to solve the above-mentioned problems, a method of supplying heated water to the mop may be considered. However, in the case where a heater is additionally installed in the cleaning module and water is heated using a large amount of electric power, a large amount of electric power needs to be supplied to the cleaning module.

Korean Patent No. KR0738478B1 discloses a vacuum cleaner capable of steam cleaning and dust collection.

The vacuum cleaner is composed of a steam cleaner and a vacuum cleaner, and the steam cleaner supplies power to the vacuum cleaner.

However, because the vacuum cleaner is powered based on the power-hungry vapor cleaner, the vacuum cleaner needs to receive power through a wire or use a large battery, which limits the application of this vacuum cleaner concept to a handheld vacuum cleaner.

Therefore, it is necessary to provide a large amount of power to the cleaning module to heat the water, and further, it is necessary to maintain the time that the entire cleaner can perform cleaning operations.

In addition, in order to increase the capacity of the relatively heavy battery, it is necessary to distribute the weight so that the user does not feel discomfort when using the vacuum cleaner.

The dust box compression rod 173 may be disposed outside the dust box 170 or the dust separation part 130 so as to be able to move up and down. The dust box compression rod 173 may be connected to the compression member 174 . When the dust box compression rod 173 is moved downward by external force, the compression member 174 can also move downward. Therefore, it is possible to provide convenience to the user. The compressing member 174 and the dust box compressing rod 173 can be returned to their original positions by an elastic member (not shown). Specifically, when the external force applied to the dust box compression lever 173 is eliminated, the elastic member may move the dust box compression lever 173 and the compression member 174 upward.

A compression member 174 may be provided in the dust box main body 171 . The compression member 174 may move in the inner space of the dust box main body 171 . Specifically, the compression member 174 may move up or down in the dust box main body 171 . Accordingly, the compression member may compress the dust in the dust box main body 171 downward. In addition, when the discharge cover 172 is separated from the dust box main body 171 and thus the lower side of the dust box 170 is opened, the compression member 174 can move from the upper side of the dust box 170 to the lower side of the dust box 170, thereby removing debris in the dust box 170. Debris, such as residual dust. Therefore, the suction force of the vacuum cleaner can be improved by preventing residual dust from remaining in the dust box 170 .

As another example, the battery case 180 and the battery 190 may be integrated in a state where the battery case 180 accommodates the battery 190 .

The battery 190 powers the vacuum cleaner 1 . Specifically, the battery 190 can supply power to the suction motor 140 , and supply power to electronic circuits and electronic components through wires embedded in the vacuum cleaner 1 . In addition, the battery 190 can provide power for the cleaning module 300 .

In a case where the battery 190 is coupled to the battery case 180, a lower side of the battery 190 may be exposed to the outside. Since the battery 190 can be placed on the floor when the cleaner 1 is placed on the floor, the battery 190 can be separated from the battery case 180 immediately. In addition, since the lower side of the battery 190 is exposed to the outside and thus directly contacts the air outside the battery 190, performance of cooling the battery 190 may be improved.

Meanwhile, in the case where the battery 190 is integrally fixed to the battery case 180, the number of structures for attaching or detaching the battery 190 and the battery case 180 can be reduced, and as a result, the overall size and weight of the cleaner 1 can be reduced.

The cleaner 1 may include an extension pipe 200 .

The extension pipe 200 can be coupled to the cleaner main body 100 and the cleaning module 300 .

For example, the extension tube 200 may be formed in a long cylindrical shape. Therefore, the inner space of the extension pipe 200 can communicate with the inner space of the cleaning module 300 . In addition, the extension pipe 200 may communicate with a suction flow path formed in the suction part 120 of the cleaner main body 100 .

When the suction motor 140 generates suction, the suction can be provided to the cleaning module 300 through the suction component 120 and the extension tube 200 . Therefore, external dust and air can be introduced into the main body 100 of the vacuum cleaner through the cleaning module 300 and the extension pipe 200 . In addition, the dust and air introduced through the cleaning module 300 may pass through the extension pipe 200 and then be introduced into the cleaner main body 100 . In addition, dust and air introduced into the cleaner body 100 and passed through the suction part 120 may be separated from the dust separating part 130 , the dust may be stored in the dust box 170 , and the air may be discharged to the outside through the exhaust cover 150 .

Meanwhile, electric wires may be embedded in the extension tube 200 . Therefore, the cleaner main body 100 and the cleaning module 300 can be electrically connected to each other through the extension tube 200 .

4 to 8 are views for explaining a cleaning module according to an embodiment of the present invention.

Referring to FIGS. 4 to 8 , the cleaning module 300 according to an embodiment of the present invention may include: a module case 310 ; and a connection pipe 380 connected to the module case 310 and configured to be movable.

For example, the cleaning module 300 according to the present embodiment can be used in a state of being connected to a handheld vacuum cleaner.

In other words, the cleaning module 300 can be detachably connected to the cleaner main body 100 or the extension pipe 200 . Therefore, when the cleaning module 300 is connected to the cleaner main body 100 or the extension pipe 200, the user can use the cleaning module 300 to clean the floor surface. In this case, the cleaner main body 100 connected to the cleaning module 300 can separate the dust in the air through the multi-cyclone method.

The cleaning module 300 may be operated by power supplied from the cleaner body 100 . Specifically, the cleaning module 300 may operate by receiving power from the battery 190 of the cleaner main body 100 .

Since the cleaner main body 100 connected to the cleaning module 300 includes the suction motor 140, the suction force generated by the suction motor 140 can be applied in the cleaning module 300 so that the cleaning module 300 can suck air and debris on the floor surface. .

Therefore, in this embodiment, the cleaning module 300 is used to suck air and debris from the floor surface, and guide the air and debris to the vacuum cleaner 1 .

The connection pipe 380 may be connected to a central portion of the rear side of the module case 310 and guide the introduced air to the cleaner body 100, but the present invention is not limited thereto.

The direction according to the present embodiment will be defined to help understanding of the present invention.

In addition, based on the state of the air inlet 313a observed from the connecting pipe 380, the left side of the flow path forming part 313 can be defined as the left side of the cleaning module 300, and the right side of the flow path forming part 313 can be defined as the right side of the cleaning module 300. In addition, the direction which connects left and right is called a left-right direction. A left/right direction may refer to a direction perpendicular to a forward/backward direction on a horizontal plane.

In addition, based on the state where the cleaning module 300 is placed on the floor surface, that is, the state where the mop 350 is placed on the floor surface and can wipe the floor surface, the direction toward the floor surface can be defined as the lower side or the lower side, and the direction away from the floor surface Direction can be defined as upper side or upper side.

The cleaning module 300 may further include a rotating cleaning unit 340 rotatably disposed on the lower side of the module housing 310 .

For example, a pair of rotating cleaning units 340 may be arranged in left and right directions. In this case, the pair of rotary cleaning units 340 may rotate independently. For example, the rotary cleaning unit 340 may include: a first rotary cleaning unit 341 ; and a second rotary cleaning unit 342 .

Rotary cleaning unit 340 may be coupled to mop 350 . For example, the mop 350 may be formed in a disc shape. The mop 350 may include: a first mop 351 ; and a second mop 352 .

In a state where the mop 350 is placed on the floor surface, the mop 350 is in close contact with the floor surface due to the load of the cleaning module 300, so that friction between the mop 350 and the floor surface increases.

The module case 310 may define the outer shape of the cleaning module 300 and has an air inlet 313a through which air is introduced. For example, the air inlet 313a may be formed at the front end of the lower side of the module case 310 . The air inlet 313a may extend from the module case 310 in left and right directions.

The module case 310 may include: a lower case 311 ; and an upper case 312 coupled to an upper side of the lower case 311 .

The rotary cleaning unit 340 is installed on the lower case 311 , and the lower case 311 may define the outer shape of the cleaning module 300 .

An air inlet 313 a may be formed in the lower case 311 .

A board mounting part may be provided on the lower case 311, and a printed circuit board 390 for controlling the mop driving motor 370 is mounted on the board mounting part. For example, the board mounting part may be provided in the form of a hook extending upward from the lower case 311 .

The board mounting part may be provided on the lower case 311 at one side of the flow path forming part 313, but the present invention is not limited thereto. For example, the printed circuit board 390 may be disposed adjacent to the first operation part 391 and the second operation part 392 . Therefore, the switch installed on the printed circuit board 390 can detect the operation of the first first operating part 391 and the second operating part 392 .

Nozzle holes (not shown) may be formed in the lower case 311, and the diffuser 337 may penetrate the nozzle holes. The water or steam (water vapor) that has passed through the steam generator 336 and the diffuser 337 may be supplied to the mop 350 through a nozzle hole (not shown).

The upper case 312 may cover the upper side of the lower case 311 and define the outer shape of the cleaning module 300 according to the present invention.

In addition, the module case 310 may further include a flow path forming part 313 configured to define a flow path communicating with the air inlet 313 a and guiding air introduced from the air inlet 313 a to the cleaner main body 100 .

The flow path forming part 313 may be coupled to a central portion of the upper side of the lower case 311 , and one end of the flow path forming part 313 may be coupled to the connection pipe 380 .

Therefore, the intake port 313a can extend substantially linearly in the front-rear direction along with the arrangement of the flow path forming portion 313 . Therefore, the length of the air inlet 313a can be minimized, and the loss of the flow path in the cleaning module 300 can be minimized.

The front side of the flow path forming part 313 may cover the upper side of the air inlet 313a. The flow path forming part 313 may be provided such that the flow path forming part 313 is inclined upward in a direction from the front end to the rear side of the flow path forming part 313 .

Therefore, the height of the front side of the flow path forming portion 313 may be lower than the height of the rear side of the flow path forming portion 313 .

According to the present embodiment, the height of the front side of the flow path forming part 313 is low, which makes it possible to reduce the height of the front side of the cleaning module 300 based on the overall height of the cleaning module 300 . The lower the height of the cleaning module 300, the higher the possibility of the cleaning module 300 entering and cleaning a narrow space under furniture or chairs.

The baffle 314 is disposed on the bottom surface of the lower case 311 . The baffle 314 can block the front space where the air inlet 313a is arranged and the rear space where the mop 350 is arranged, thereby preventing the moisture discharged from the mop 350 from diffusing to the air inlet 313a. For example, the baffle 314 may include: a central portion 314a; and an extension portion 314b. In this case, a pair of extension parts 314b may be symmetrically connected to opposite ends based on the central part 314a. In addition, the central portion 314a may be disposed on the rear side of the air inlet 313a, and prevent moisture from flowing toward the air inlet 313a. In addition, the extension portion 314b may have an arc shape and surround the circular mop 350 .

A plurality of rollers may be provided on the lower side of the lower case 311 and allow the cleaning module 300 to move smoothly.

For example, the front roller 315 may be provided on the lower housing 311 and located on the front side of the mop 350 . The front roller 315 may include: a first roller 315a; and a second roller 315b. The first roller 315a and the second roller 315b may be disposed spaced apart from each other in the left-right direction.

The first roller 315a and the second roller 315b may be rotatably connected to the shaft, respectively. The shaft may be fixed to the lower side of the lower case 311 in a state where the shaft extends in the left-right direction.

The distance between the shaft and the front end of the lower case 311 may be longer than the minimum distance between the mop 350 and the front end of the lower case 311 .

For example, the rotary sweeping unit 340 may be located at least partially between the axis of the first roller 315a and the axis of the second roller 315b.

Through this configuration, the rotary cleaning unit 340 can be located as close as possible to the air inlet 313a, and the area of the floor surface on which the cleaning module 300 is located and on which the rotary cleaning unit 340 performs a cleaning operation can be increased, thereby improving cleaning. performance of the floor.

In this embodiment, the first roller 315 a and the second roller 315 b are connected to the lower side of the lower housing 311 , which makes it possible to improve the mobility of the cleaning module 300 .

A third roller 316 may be further disposed on the lower side of the lower housing 311 . Therefore, the first and second rollers 315a, 315b and the third roller 316 may support the cleaning module 300 at three points. In this case, the third roller 316 may be located at the lower side of the mop 350 so as not to interfere with the mop 350 .

The module case 310 may have: a cooling air inlet 317 ; and a cooling air discharge 318 .

The lower case 311 may have a cooling air inlet 317 . External air may be introduced into the module case 310 through the cooling air inlet 317 . In addition, a cooling air inlet 317 may be formed in a front sidewall of the lower case 311 . Through this configuration, when the cleaning module 300 is moved forward by the user's operation, the amount of air to be introduced increases.

The upper housing 312 may have a cooling air discharge port 318 . Air in the module case 310 may be discharged to the outside through the cooling air discharge port 318 . In addition, cooling air discharge ports 318 may be formed in sidewalls of opposite sides of the upper case 312 . With this configuration, the air introduced through the cooling air inlet 317 can be guided through the mop driving motor 370 while the air flows to the cooling air discharge port 318, which makes it possible to prevent the mop driving motor 370 from overheating.

In addition, the cooling air discharge port 318 may be disposed farther from the ground than the cooling air inlet 317 based on a state where the lower housing 311 is placed on the floor surface. With this configuration, the heated air can move upward in the module housing 310 and be efficiently discharged through the cooling air discharge port 318 .

The cleaning module 300 may further include a water tank 320 capable of supplying water to the mop 350 .

The water tank 320 may be detachably connected to the module case 310 . Specifically, the water tank 320 is mounted on a water container seat formed on the upper case 312 .

In addition, the water tank 320 may be disposed above the steam generator 336 . Specifically, the water tank 320 is disposed above the steam generator 336 and spaced apart from the steam generator 336 . That is, the water tank 320 may be disposed above the steam generator 336 with the upper case 312 interposed therebetween.

When the water box 320 is installed on the module casing 310 , the water box 320 can define the appearance of the cleaning module 300 .

The entire upper sidewall of the water tank 320 can substantially define the upper appearance of the cleaning module 300 . Therefore, the user can visually check whether the water tank 320 is installed on the module case 310 .

The module case 310 may further include a water tank separation button configured to be operated by a user to separate the water tank 320 in a state in which the water tank 320 is installed on the module case 310 . For example, a tank disconnect button may be located on the central portion of the cleaning module 300 . Therefore, the user easily recognizes the water tank separation button and operates the water tank separation button.

In a state where the water tank 320 is installed on the module case 310 , water in the water tank 320 may be supplied to the mop 350 .

Specifically, a space capable of storing water is formed in the water tank 320 . Water stored in the water tank 320 may be supplied to the steam generator 336 through at least one hose. According to the user's selection, the water introduced into the steam generator 336 may be heated and phase changed into steam (water vapor). Water heated by the steam generator 336 may be supplied to the mop 350 through the diffuser 337 .

The water tank 320 contains a water supply port. The water supply port is a hole through which water is introduced into the water tank 320 . For example, a water supply port may be formed in a side of the water tank 320 .

The water tank 320 contains a drain. The drain port is a hole through which water stored in the water tank 320 is discharged. Water discharged from the drain may flow to the steam generator 336 . A drain port may be formed in a lower surface of the water tank 320 .

The tank 320 contains air holes. Air holes are holes through which air can be introduced into the water tank 320 . When the water stored in the water tank 320 is discharged to the outside, the pressure in the water tank 320 decreases, and air may be introduced into the water tank 320 through air holes to compensate for the decreased pressure. For example, air holes may be formed at the upper end of the water tank 320 .

The cleaning module 300 according to the present invention may further include a water supply unit 330 having a flow path through which water introduced from the water tank 320 is supplied to the mop 350 .

Specifically, the water supply unit 330 may include: a water tank connection part 331 configured to introduce water in the water tank 320 into the module housing 310; a water inlet pipe 332 configured to supply the water introduced into the water tank connection part 331 to the water pump 333; a guide pipe 334 configured to supply water from the water pump 333 to the 'T'-shaped connector; and a water supply pipe 335 configured to supply water introduced into the connector to the steam generator 336 .

The water tank connection part 331 may be coupled to the lower side of the upper case 312 , and a part of the water tank connection part 331 may protrude upward while penetrating the upper case 312 .

When the water tank 320 is seated on the upper case 312 , the upwardly protruding water tank connection part 331 may be retracted into the water tank 320 while passing through the discharge port of the water tank 320 .

The upper case 312 may include a seal to prevent water discharged from the water tank 320 from leaking from the periphery of the water tank connection part 331 . For example, the seal may be made of rubber, coupled to the upper case 312 , and disposed on an upper side of the upper case 312 .

A water pump 333 may be installed on the upper case 312 and controls discharge of water in the water tank 320 .

The water pump 333 can provide flow power to the water. The water pump 333 may include: a first connection port connected to the water inlet pipe 332 ; and a second connection port connected to the guide pipe 334 . In this case, based on the water pump 333, the first connection port may be an inlet, and the second connection port may be an outlet.

The water pump 333 is a pump in which a valve body operates to expand or contract water and communicate the first connection port and the second connection port with each other. Since the water pump 333 can be implemented by a known structure, its detailed description will be omitted.

The water supply pipe 335 may connect the connector to the water inlet 336b of the steam generator 336 . For example, the water supply pipe 335 may be a pair of pipes branching from the connector.

Accordingly, the water supplied to the water inlet pipe 332 flows into the water pump 333 and then flows into the guide pipe 334 . The water flowing through the guide pipe 334 flows to the water supply pipe 335 through the connector. In addition, water flowing through the water supply pipe 335 is supplied to the steam generator 336 .

The steam generator 336 is a device for heating water. The steam generator 336 is disposed in the module housing 310 . Specifically, the steam generator 336 is installed on the upper side of the lower housing 311 .

The steam generator 336 includes: a heating chamber 336a; a water inlet 336b; and a moisture outlet 336c.

A flow path through which water introduced from the water tank 320 may flow is formed in the heating chamber 336a. The heating chamber 336 a may heat water by receiving power from the battery 190 and/or the auxiliary battery 500 . The heating chamber 336a can adjust the temperature of the water under the control of the user. In addition, the heating chamber 336a can change the phase of water into vapor (water vapor) under the control of the user.

The water inlet 336b may be a hole formed at an inlet end of the heating chamber 336a. Water stored in the water tank 320 may be introduced into the steam generator 336 through the water inlet 336b.

The moisture discharge port 336c may be a hole formed at an outlet end of the heating chamber 336a. Water or steam can be discharged from the steam generator 336 through the moisture outlet 336c. The moisture discharge port 336c may be connected to the diffuser 337 .

Meanwhile, in the present invention, the steam generator 336 is arranged to be inclined. Specifically, the heating chamber 336a is arranged to be inclined at a predetermined angle with respect to the ground (floor surface).

For example, the rear end of the heating chamber 336a is disposed upward from the front end of the heating chamber 336a. That is, the steam generator 336 is inclined upward in a direction toward the rear side. Accordingly, water may be heated while flowing from the rear upper side to the front lower side of the steam generator 336 .

Meanwhile, the water inlet 336b may be disposed at the rear end of the heating chamber 336a, and the moisture discharge port 336c may be disposed at the front end of the heating chamber 336a. That is, based on a state where the lower case 311 is placed on the floor surface (ground), the water inlet 336b may be disposed farther from the floor surface (ground) than the moisture discharge port 336c. Therefore, water is heated while flowing from the upper side to the lower side by gravity, so that even if the water rises while the phase becomes moisture, it can be discharged from the moisture discharge port 336c through the flow force of the water.

Diffuser 337 is configured to drain water from tank 320 to mop 350 .

The diffuser 337 may be accommodated in a space formed in the module case 310 . The diffuser 337 may be connected to the steam generator 336 and discharge moisture heated by the steam generator 336 to the mop 350 .

For example, a pair of diffusers 337 may be mounted on the module housing 310 and arranged in left and right directions. In addition, the pair of diffuser plates 337 arranged in the left-right direction may be formed symmetrically (mirror-symmetrically).

In this embodiment, the diffuser 337 may have a diffusion flow path therein through which moisture may flow, and the diffuser 337 may include a nozzle through which the moisture flowing through the diffusion flow path is discharged to the mop.

For example, the diffuser 337 may have an arc shape, a plurality of nozzles may be provided, and a plurality of nozzles may be provided at predetermined intervals. Through this configuration, the diffuser 337 can stably supply moisture to the mop 350 having a disc shape.

As another example, the diffuser 337 may have a ring shape (ring shape), and a plurality of nozzles may be arranged at predetermined intervals in the circumferential direction. In this case, the mop drive motor 370 may be disposed within the annular diffuser. Through this configuration, the diffuser 337 can quickly supply moisture to the entire mop 350 having a disc shape.

The water sprayed from the diffuser 337 passes through a water passage hole formed in the rotary cleaning unit 340 and is supplied to the mop 350 . In a state where the mop 350 absorbs water supplied through the diffuser 337, the mop 350 wipes the floor while rotating.

The rotary cleaning unit 340 may rotate by receiving power from the mop driving motor 370 . For example, the rotating cleaning unit 340 may be a rotating plate. The rotary cleaning unit 340 may have a disc shape, and a mop 350 may be attached to a lower surface of the rotary cleaning unit 340 .

For example, the rotary cleaning unit 340 may be disposed on the lower side of the module casing 310 and located at the rear side of the air inlet 313a.

Therefore, when the cleaning module 300 performs a cleaning operation while moving forward, debris and air on the floor surface may be sucked into the air inlet 313 a, and then the floor surface may be wiped by the mop 350 .

For example, the rotary cleaning unit 340 may comprise: a first rotary cleaning unit 341 connected to a first mop drive motor 371 and attached to the first mop 351; and a second rotary cleaning unit 342 connected to a second mop drive motor 372 and Attached to the second mop 352 .

Specifically, the rotary cleaning unit 340 may include: an outer body having a ring shape; an inner body located in a central area of the outer body and spaced apart from the inner peripheral surface of the outer body; and a plurality of connecting ribs configured to connect the inner The outer peripheral surface of the body is connected to the inner peripheral surface of the outer body.

In addition, the rotary cleaning unit 340 may include a plurality of water passing holes formed in a circumferential direction to supply the mop 350 with water discharged through the diffuser 337 .

Meanwhile, the rotary cleaning unit 340 may include an attachment device to which the mop 350 is attached. For example, the attachment means may be Velcro fasteners.

A rotary cleaning unit 340 may be disposed at a lower side of the lower case 311 . That is, the rotary cleaning unit 340 may be disposed outside the module case 310 .

In addition, the rotary cleaning unit 340 may be connected to the mop driving motor 370 and receive power. For example, the rotary cleaning unit 340 may be connected to the mop driving motor 370 through at least one gear, and rotated by the operation of the mop driving motor 370 .

The rotary cleaning unit 340 may include: a first rotary cleaning unit 341 ; and a second rotary cleaning unit 342 .

In this embodiment, the rotation center of the first rotation cleaning unit 341 and the rotation center of the second rotation cleaning unit 342 are spaced apart from each other in the left-right direction.

The rotation center of the rotary cleaning unit 340 may be located farther from the front end of the module case 310 than the central axis that bisects the length of the module case 310 based on the front/rear direction. This is to prevent the rotary cleaning unit 340 from clogging the air inlet 313a.

The distance between the rotation center of the first rotation cleaning unit 341 and the rotation center of the second rotation cleaning unit 342 may be greater than the diameter of the mop 350 . This is to reduce the friction between the first mop 351 and the second mop 352 caused by the interference between the first mop 351 and the second mop 352 when the first mop 351 and the second mop 352 rotate, and to prevent the friction between the first mop 351 and the second mop 352. The first mop 351 and the second mop 352 interfere with each other to reduce a part of the cleaning area.

The mop 350 can wipe the floor surface while rotating.

The mop 350 may be coupled to a lower side of the rotary cleaning unit 340 and face the floor surface.

The mop 350 is configured such that a floor-facing bottom surface of the mop 350 has a predetermined area. The mop 350 has a flat shape. The mop 350 is configured such that the width (or diameter) of the mop 350 in the horizontal direction is sufficiently larger than the height of the mop 350 in the vertical direction. When the mop 350 is coupled to the lower housing 311, the bottom surface of the mop 350 may be parallel to the floor surface.

The bottom surface of the mop 350 may have a substantially circular shape, and the mop 350 may have a rotationally symmetrical shape as a whole. In addition, the mop 350 may be attached to or detached from the bottom surface of the rotary cleaning unit 340 . The mop 350 may be coupled to the rotary cleaning unit 340 and rotate together with the rotary cleaning unit 340 .

In the state where the rotary cleaning unit 340 is coupled to the lower side of the module housing 310, a part of the mop 350 protrudes outward from the cleaning module 300, so that the mop 350 not only cleans a part of the floor surface located under the cleaning module 300, but also Cleans the portion of the floor surface located outwardly from the sweeping module 300 .

For example, the mop 350 may not only protrude toward opposite sides of the cleaning module 300, but may also protrude backward.

The mop 350 may include: a first mop 351 coupled to the first rotary cleaning unit 341 ; and a second mop 352 coupled to the second rotary cleaning unit 342 . Therefore, when the first rotating cleaning unit 341 rotates by receiving power from the first mop driving motor 371 , the first mop 351 may also rotate. When the second rotating cleaning unit 342 rotates by receiving power from the second mop driving motor 372 , the second mop 352 may also rotate.

In this case, the light emitted from the light emitting element may be visible light. According to an embodiment, the light emitted from the light emitting element may be infrared (IR) or ultraviolet (UV). Through this configuration, when the light emitting element is operating, the user can identify whether there is debris or microorganisms at the position in front of the cleaning module 300 . In addition, the light-emitting elements may sterilize or eliminate debris or microorganisms present at a location in front of the cleaning module 300, thereby improving sanitation.

In addition, a diffusion plate may be provided in front of the light emitting element and diffuse light emitted from the light emitting element.

Specifically, the mop driving motor 370 may include a first mop driving motor 371 configured to rotate the first rotary cleaning unit 341 ; and a second mop driving motor 372 configured to rotate the second rotary cleaning unit 342 .

As described above, the first mop driving motor 371 and the second mop driving motor 372 operate independently. Therefore, even if any one of the first mop driving motor 371 and the second mop driving motor 372 fails, the rotary cleaning unit 340 can be rotated by the other one of the first mop driving motor 371 and the second mop driving motor 372 .

The first connection pipe 381 may be arranged such that the cutout portion points upward to the second connection pipe 382 . Through this configuration, when the cleaning module 300 is placed on the ground, the angle of the second connecting pipe 382 relative to the ground can be changed through the movement of the user's hand. That is, the first connecting pipe 381 and the second connecting pipe 382 can be used as a joint capable of adjusting the angle of the cleaning module 300 and the cleaner body 100 .

The second connection pipe 382 has a tubular shape. One axial end of the second connecting pipe 382 is rotatably coupled to the first connecting pipe 313 , and the other axial end of the second connecting pipe 382 is inserted into the second connecting pipe 382 along with the cleaner body 100 or the extension pipe 200 .
