Description

Vacuum cleaner

The present invention relates to a vacuum cleaner, and more particularly, to a vacuum cleaner comprising a detachably disposed cleaning module, the cleaning module being configured to suck dust or debris from a target cleaning area and to wipe the target cleaning area by discharging water into a mop.

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

Vacuum cleaners can be divided into manual vacuum cleaners, which are directly moved by the user to perform the cleaning operation, and automatic vacuum cleaners, which perform the cleaning operation while moving automatically.

Handheld vacuum cleaners (hand-held vacuum cleaners) offer maximum portability and are lightweight. However, due to the short length of the handheld vacuum cleaner, the cleaning area may be limited. Therefore, handheld vacuum cleaners are used to clean localized areas such as tables, sofas, or vehicle interiors.

The user can use a stick vacuum cleaner while standing, and thus can perform a cleaning operation without bending his/her waist. Therefore, the stick vacuum cleaner is advantageous for cleaning a wide area while the user moves in the area. A handheld vacuum cleaner can be used to clean a narrow space, while a stick vacuum cleaner can be used to clean a wide space and can also be used at a high place that the user's hands cannot reach. Recently, modular stick vacuum cleaners are provided, so that the type of vacuum cleaner is actively changed and used to clean various places.

The methods of cleaning floors are roughly divided into dry cleaning and wet cleaning. Dry cleaning refers to the method of wiping or vacuuming. The vacuum cleaner in the related technology adopts dry cleaning. Wet cleaning refers to the method of using a wet mop to wipe the dust for cleaning. As another wet cleaning method, there is a method of disinfecting and cleaning the floor 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 materials, wet cleaning methods cannot be performed, so only dry cleaning methods can be performed. However, recently, the floor is made of various materials such as steel plates or marble, so wet cleaning methods can be performed.

In the related art, a vacuum cleaner dedicated to dry cleaning is used to perform a dry cleaning method, and a vacuum cleaner dedicated to wet cleaning is used to perform a wet cleaning method. However, since users need to purchase two types of vacuum cleaners to clean various types of floors, it brings inconvenience to users. In order to solve the above problem, a vacuum cleaner including a single main body, a dry cleaning module and a wet cleaning module has been studied, and the dry cleaning module is installed on the main body to perform a dry cleaning method and the wet cleaning module is installed on the main body to perform a wet cleaning method.

The wet cleaning module includes: a water container configured to store water; a heater configured to generate steam by heating water; and a mop configured to mop the floor by receiving 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 installed on the main body in a state where the water container or the heater is set on the main body, unnecessary components may hinder the cleaning operation. Therefore, the water container or the heater can be set on the wet cleaning module instead of being installed on the main body to ensure easy cleaning, easy replacement of the module or space utilization.

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

However, wet mop vacuum cleaners cannot suck up dust, and most of the power is required to turn the mop, while the coupled auxiliary battery is only used to increase the usage time of the vacuum cleaner.

Furthermore, when the debris is attached to the floor, even if a vacuum cleaner configured to wipe the floor surface by rotating the mop wipes the floor by rotating the mop filled with water, the debris may still 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.

To solve the above problem, a method of heating water and supplying it to the mop can be considered. However, when a heater is additionally installed in the cleaning module and a large amount of electricity is used to heat the water, a large amount of electricity needs to be provided to the cleaning module.

Korean Patent No. KR0738478B1 discloses a vacuum cleaner capable of performing steam cleaning and vacuuming.

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

However, since the vacuum cleaner is powered on the basis of a power-hungry steam vacuum cleaner, the vacuum cleaner needs to receive power via a wire or use a large battery, which limits the application of the concept of this vacuum cleaner to a handheld vacuum cleaner.

Therefore, a large amount of electricity needs to be supplied to the cleaning module to heat the water, and further needs to be maintained for a period of time for the entire vacuum cleaner to perform a cleaning operation.

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

The term "floor surface" used in this specification refers not only to floor surfaces of rooms such as living rooms, but also to clean surfaces such as carpets.

1 to 3 , a vacuum cleaner 1 according to an embodiment of the present invention may include: a vacuum cleaner body 100 having a suction motor 140 configured to generate suction; a cleaning module 300 connected to the vacuum cleaner body 100 and configured to clean a floor surface by wiping the floor surface while sucking in air and debris; and an extension tube 200 configured to connect the vacuum cleaner body 100 and the cleaning module 300.

Next, the structure of the vacuum cleaner main body 100 will be described.

Meanwhile, in the embodiment of the present invention, the direction may be defined based on when the bottom surface (lower surface) of the dust box 170 and the bottom surface (lower surface) of the battery case 180 are placed on the ground.

In this case, the forward direction may refer to a direction in which the suction component 120 is set based on the suction motor 140, and the backward direction may refer to a direction in which the handle 160 is set. In addition, based on the state of observing the suction component 120 from the suction motor 140, the right direction may refer to a direction in which a component is set on the right side, and the left direction may refer to a direction in which a component is set on the left side. In addition, in an embodiment of the present invention, the upper side and the lower side may be defined in a direction perpendicular to the ground based on a state in which the bottom surface (lower surface) of the dust box 170 and the bottom surface (lower surface) of the battery case 180 are placed on the ground.

The vacuum cleaner 1 may include a vacuum cleaner body 100. The vacuum cleaner body 100 may include: a body housing 110; a suction component 120; a dust separation component 130; a suction motor 140; an exhaust cover 150; a handle 160; a dust box 170; a battery housing 180; and a battery 190.

The main body housing 110 may define the appearance of the vacuum cleaner body 100. The main body housing 110 may provide a space in which the suction motor 140 and a filter (not shown) may be accommodated. The main body housing 110 may be formed in a shape similar to a cylinder.

The suction member 120 may protrude outward from the main body housing 110. For example, the suction member 120 may be formed in a cylindrical shape with an inner opening. The suction member 120 may be coupled to the extension pipe 200. The suction member 120 may provide a flow path (hereinafter, referred to as a "suction flow path") through which dust-laden air may flow.

The dust separation component 130 may be connected to the suction component 120. The dust separation component 130 adopts the principle of a dust collector and uses centrifugal force to separate the dust sucked into the vacuum cleaner body 100 through the suction component 120. The space in the dust separation component 130 may be connected to the space in the dust box 170.

For example, the dust separation component 130 may have one or more cyclone components capable of separating dust by using a cyclone flow. In addition, the space in the dust separation component 130 may be connected to the suction flow path. Therefore, the air and dust introduced through the suction component 120 flow in a spiral along the inner circumferential surface of the dust separation component 130. Therefore, a cyclone flow may be generated in the inner space of the dust separation component 130.

The suction motor 140 may generate a suction force for sucking air. The suction motor 140 may be accommodated in the main body housing 110. The suction motor 140 may generate a suction force by rotating. For example, the suction motor 140 may be formed in a shape similar to a cylinder.

The exhaust cover 150 may be axially disposed on one side of the main body housing 110. The exhaust cover 150 may contain a filter for filtering air. For example, a HEPA filter may be contained in the exhaust cover 150.

The handle 160 may be grasped by the user. The handle 160 may be disposed behind the suction motor 140. For example, the handle 160 may be formed in a cylindrical shape. Alternatively, the handle 160 may be formed in a curved cylindrical shape. The handle 160 may be disposed at a predetermined angle relative to the main housing 110, the suction motor 140, or the dust separation member 130.

The handle 160 may include a holding part 161 formed in a cylindrical shape so that a user can grasp the holding part 161, a first extension part is connected to one end of the holding part 161 based on the longitudinal direction (axial direction) of the holding part 161 and extends toward the suction motor 140, and a second extension part is connected to the other end of the holding part 161 based on the longitudinal direction (axial direction) of the holding part 161 and extends toward the dust box 170.

The upper side of the handle 160 may define the appearance of a portion of the upper side of the vacuum cleaner 1 .

The operating member 165 may be provided on the handle 160. The operating member 165 may be provided on an inclined surface formed in an upper region of the handle 160. The user may input an instruction for operating or stopping the vacuum cleaner 1 through the operating member 165.

The dust box 170 may be in communication with the dust separating part 130. The dust box 170 may store the dust separated by the dust separating part 130.

The dust box 170 may include a dust box body 171 .

The dust box body 171 may provide a space capable of storing dust separated from the dust separating part 130. For example, the dust box body 171 may be formed in a shape similar to a cylinder.

For example, the dust box body 171 may be configured so that the lower side of the dust box body 171 can be opened. In this case, the discharge cover 172 may be provided at the lower side of the dust box body 171 and selectively open the lower side of the dust box body 171.

Meanwhile, according to an embodiment, the dust box 170 may further include: a dust box compression rod 173; and a compression member 174.

The dust box compression rod 173 may be disposed outside the dust box 170 or the dust separation component 130. The dust box compression rod 173 may be disposed outside the dust box 170 or the dust separation component 130 so as to be able to move upward and downward. The dust box compression rod 173 may be connected to the compression member 174. When the dust box compression rod 173 moves downward by an external force, the compression member 174 may also move downward. Therefore, it is possible to provide convenience for the user. The compression member 174 and the dust box compression rod 173 may return to their original positions by means of an elastic member (not shown). Specifically, when the external force applied to the dust box compression rod 173 is removed, the elastic member can move the dust box compression rod 173 and the compression member 174 upward.

The compression member 174 may be disposed in the dust box body 171. The compression member 174 may be movable in the inner space of the dust box body 171. Specifically, the compression member 174 may be moved upward or downward in the dust box body 171. Therefore, the compression member may compress the dust in the dust box body 171 downward. In addition, when the discharge cover 172 is separated from the dust box body 171 and thus the lower side of the dust box 170 is opened, the compression member 174 may be moved 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, such as residual dust. Therefore, the suction force of the vacuum cleaner can be improved by preventing the remaining dust from being retained in the dust box 170. In addition, the unpleasant odor caused by the remaining dust can be removed by preventing the remaining dust from being retained in the dust box 170.

The battery 190 may be accommodated in the battery case 180. The battery case 180 may be disposed at a lower side of the handle 160.

For example, the battery case 180 may have a hexahedral shape with an opening at its lower side. The rear side of the battery case 180 may be connected to the handle 160. In this case, the battery case 180 may include a receiving part with an opening at its lower side. With this configuration, the battery 190 may be attached or detached through the receiving part of the battery case 180.

As another example, the battery case 180 and the battery 190 may be integrally combined in a state in which the battery case 180 accommodates the battery 190 .

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

In the case where the battery 190 is coupled to the battery case 180, the lower side of the battery 190 may be exposed to the outside. Since the battery 190 may be placed on the floor when the vacuum cleaner 1 is placed on the floor, the battery 190 may be immediately separated from the battery case 180. 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, the performance of cooling the battery 190 may be improved.

At the same time, when 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 of the vacuum cleaner 1 and the weight of the vacuum cleaner 1 can be reduced.

The vacuum cleaner 1 may include an extension pipe 200 .

The extension tube 200 may be coupled to the vacuum cleaner 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 tube 200 may communicate with the inner space of the cleaning module 300. In addition, the extension tube 200 may communicate with the suction flow path formed in the suction component 120 of the vacuum cleaner body 100.

When the suction motor 140 generates suction, the suction may be provided to the cleaning module 300 through the suction member 120 and the extension pipe 200. Therefore, external dust and air may be introduced into the vacuum cleaner body 100 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 vacuum cleaner body 100. In addition, the dust and air introduced into the vacuum cleaner body 100 and having passed through the suction member 120 may be separated from the dust separation member 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.

At the same time, the wire can be embedded in the extension tube 200. Therefore, the vacuum cleaner 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.

4 to 8 , the cleaning module 300 according to the embodiment of the present invention may include: a module housing 310; and a connecting pipe 380 connected to the module housing 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 vacuum cleaner body 100 or the extension tube 200. Therefore, when the cleaning module 300 is connected to the vacuum cleaner body 100 or the extension tube 200, the user can clean the floor surface using the cleaning module 300. In this case, the vacuum cleaner body 100 connected to the cleaning module 300 can separate dust in the air by a multi-cyclone method.

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

Since the vacuum cleaner 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 to the cleaning module 300, so that the cleaning module 300 can suck in the 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 connecting pipe 380 may be connected to a central portion of the rear side of the module housing 310 and guide the introduced air to the vacuum cleaner body 100, but the present invention is not limited thereto.

The direction according to the present embodiment will be defined to help understand the present invention. A portion of the cleaning module 300 connected to the connecting tube 380 may be defined as the rear portion (rear side) of the cleaning module 300, and a portion of the cleaning module 300 relative to the connecting tube 380 may be defined as the front portion (front side) of the cleaning module 300.

In addition, based on the state of the air inlet 313a observed from the connecting tube 380, the left side of the flow path forming portion 313 can be defined as the left side of the cleaning module 300, and the right side of the flow path forming portion 313 can be defined as the right side of the cleaning module 300. In addition, the direction of the left and right connection is referred to as the left and right direction. The left/right direction can refer to a direction perpendicular to the forward/backward direction on the horizontal plane.

In addition, based on the state in which the cleaning module 300 is placed on the floor surface, that is, 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 can be defined as the upper side or the upper side.

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

For example, a pair of rotary cleaning units 340 may be arranged in the 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.

The rotary cleaning unit 340 may be coupled to a mop 350. For example, the mop 350 may be formed in a circular plate 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 the friction between the mop 350 and the floor surface increases.

The module housing 310 may define the outer shape of the cleaning module 300 and have 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 housing 310. The air inlet 313a may extend from the module housing 310 in the left-right direction.

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

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

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

The board mounting portion can be arranged on the lower housing 311, and the printed circuit board 390 for controlling the mop driving motor 370 is mounted on the board mounting portion. For example, the board mounting portion can be arranged in the form of a hook extending upward from the lower housing 311.

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

A nozzle hole (not shown) may be formed in the lower housing 311, and the diffuser 337 may penetrate the nozzle hole. Water or steam (water vapor) having passed through the steam generator 336 and the diffuser 337 may be supplied to the mop 350 through the nozzle hole (not shown).

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

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

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

Therefore, the air inlet 313a can extend substantially straight 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 portion 313 may cover the upper side of the air inlet 313a. The flow path forming portion 313 may be provided so that the flow path forming portion 313 is inclined upward in a direction from the front end to the rear side of the flow path forming portion 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 portion 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 that the cleaning module 300 enters and cleans the narrow space under furniture or chairs.

The baffle 314 is disposed on the bottom surface of the lower housing 311. The baffle 314 may block the front space where the air inlet 313a is disposed and the rear space where the mop 350 is disposed, 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 portions 314b may be symmetrically connected to opposite ends based on the central portion 314a. In addition, the central portion 314a may be disposed at the rear side of the air inlet 313a and prevent moisture from flowing to 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 disposed on the lower side of the lower housing 311 and allow the cleaning module 300 to move smoothly.

For example, the front roller 315 may be disposed on the lower housing 311 and located at 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 to be 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 housing 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 housing 311 may be longer than the minimum distance between the mop 350 and the front end of the lower housing 311.

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

Through this configuration, the rotary cleaning unit 340 can be located maximally close 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 the performance of cleaning the floor.

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

The third roller 316 may be further disposed on the lower side of the lower housing 311. Therefore, the first roller 315a, the second roller 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 housing 310 may have: a cooling air inlet 317; and a cooling air exhaust port 318.

The lower housing 311 may have a cooling air inlet 317. External air may be introduced into the module housing 310 through the cooling air inlet 317. In addition, the cooling air inlet 317 may be formed in the front side wall of the lower housing 311. With this configuration, when the cleaning module 300 moves 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. The air in the module housing 310 may be discharged to the outside through the cooling air discharge port 318. In addition, the cooling air discharge port 318 may be formed in the side walls on opposite sides of the upper housing 312. With this configuration, the air introduced through the cooling air inlet 317 may be guided through the mop drive motor 370 while the air flows toward the cooling air discharge port 318, which makes it possible to prevent the mop drive motor 370 from overheating.

In addition, based on the state that the lower housing 311 is placed on the floor surface, the cooling air discharge port 318 can be set farther from the ground than the cooling air inlet 317. Through this configuration, the heated air can move upward in the module housing 310 and be effectively 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 housing 310. Specifically, the water tank 320 is mounted on a water container seat formed on the upper housing 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 is spaced apart from the steam generator 336. That is, the water tank 320 may be disposed above the steam generator 336, with the upper housing 312 interposed therebetween.

When the water tank 320 is mounted on the module housing 310 , the water tank 320 may define the appearance of the cleaning module 300 .

The entire upper side wall 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 housing 310.

The module housing 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 where the water tank 320 is mounted on the module housing 310. For example, the water tank separation button may be located on a 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 mounted on the module housing 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. The 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). The water heated by the steam generator 336 may be supplied to the mop 350 through the diffuser 337.

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

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

The water tank 320 includes an air hole. The air hole is a hole through which air can be introduced into the water tank 320. When water stored in the water tank 320 is discharged to the outside, the pressure in the water tank 320 is reduced, and air can be introduced into the water tank 320 through the air hole to compensate for the reduced pressure. For example, the air hole 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 moisture supply unit 330 may include: a water tank connection portion 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 portion 331 to a water pump 333; a guide pipe 334, configured to supply water from the water pump 333 to a "T"-shaped connector; and a water supply pipe 335, configured to supply the water introduced into the connector to a steam generator 336.

The water tank connection portion 331 can operate a valve (not shown) in the water tank 320 , and water can flow in the water tank connection portion 331 .

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

When the water tank 320 is placed on the upper housing 312, the water tank connection portion 331 protruding upward may be retracted into the water tank 320 while passing through the discharge port of the water tank 320.

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

The water pump 333 may be mounted on the upper housing 312 and control the discharge of water in the water tank 320 .

The water pump 333 can provide flow force to the water. The water pump 333 can 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 can be an inlet, and the second connection port can be an outlet.

The water pump 333 is a pump in which a valve body operates to expand or contract water and connect the first connection port and the second connection port to each other. Because 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 branched from the connector.

Therefore, 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, the 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 arranged 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 is formed in the heating chamber 336a, through which water introduced from the water tank 320 can flow. The heating chamber 336a can heat the 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 the water into steam (water vapor) under the control of the user.

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

The moisture drain port 336c may be a hole formed at the outlet end of the heating chamber 336a. Water or steam may be discharged from the steam generator 336 through the moisture drain port 336c. The moisture drain 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 relative 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 tilted upward in the direction toward the rear side. Therefore, water can be heated while flowing from the rear upper side to the front lower side of the steam generator 336.

At the same time, the water inlet 336b can be set at the rear end of the heating chamber 336a, and the moisture outlet 336c can be set at the front end of the heating chamber 336a. That is, based on the state that the lower housing 311 is placed on the floor surface (ground), the water inlet 336b can be set farther from the floor surface (ground) than the moisture outlet 336c. Therefore, the water is heated while flowing from the upper side to the lower side under the action of gravity, so that even if the water rises while becoming humid in phase, it can be discharged from the moisture outlet 336c through the flow force of the water.

The diffuser 337 is configured to discharge the water in the water tank 320 to the mop 350.

The diffuser 337 may be accommodated in a space formed in the module housing 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 the left-right direction. In addition, the pair of diffusers 337 arranged in the left-right direction may be formed symmetrically (mirror symmetry).

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, may be provided with a plurality of nozzles, and may be provided with a plurality of nozzles at predetermined intervals. Through this configuration, the diffuser 337 may stably supply moisture to the mop 350 having a circular plate shape.

As another example, the diffuser 337 may have an annular 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 arranged in the annular diffuser. Through this configuration, the diffuser 337 may quickly supply moisture to the entire mop 350 having a circular plate shape.

The water sprayed from the diffuser 337 passes through the water-through hole formed in the rotary cleaning unit 340 and is then supplied to the mop 350. In a state where the mop 350 absorbs the 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 rotary cleaning unit 340 may be a rotary plate. The rotary cleaning unit 340 may have a circular plate shape, and the mop 350 may be attached to the lower surface of the rotary cleaning unit 340.

For example, the rotary cleaning unit 340 can be disposed on the lower side of the module housing 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 can be sucked into the air inlet 313a, and then the floor surface can be wiped by the mop 350.

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

Specifically, the rotary cleaning unit 340 may include: an outer body having a toroidal shape; an inner body located in the central region of the outer body and spaced apart from the inner circumference of the outer body; and a plurality of connecting ribs configured to connect the outer circumference of the inner body to the inner circumference of the outer body.

In addition, the rotary cleaning unit 340 may include a plurality of water 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 device may be a Velcro fastener.

The rotary cleaning unit 340 may be disposed on the lower side of the lower housing 311. That is, the rotary cleaning unit 340 may be disposed outside the module housing 310.

In addition, the rotary cleaning unit 340 may be connected to the mop drive motor 370 and receive power. For example, the rotary cleaning unit 340 may be connected to the mop drive motor 370 via at least one gear and rotated by the operation of the mop drive 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 rotary cleaning unit 341 and the rotation center of the second rotary 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 positioned farther from the front end of the module housing 310 than the central axis that bisects the length of the module housing 310 based on the front/rear direction. This is to prevent the rotary cleaning unit 340 from blocking the air inlet 313a.

The distance between the rotation center of the first rotary cleaning unit 341 and the rotation center of the second rotary 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 first mop 351 and the second mop 352 from interfering with each other and reducing a portion of the cleanable area.

The Mop 350 can wipe the floor surface while rotating.

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

The mop 350 is configured so that the bottom surface of the mop 350 facing the floor has a predetermined area. The mop 350 has a flat shape. The mop 350 is configured so that the width (or diameter) of the mop 350 in the horizontal direction is sufficiently greater 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.

When the rotary cleaning unit 340 is coupled to the lower side of the module housing 310, a portion of the mop 350 protrudes outward from the cleaning module 300, so that the mop 350 cleans not only a portion of the floor surface below the cleaning module 300, but also a portion of the floor surface outside the cleaning 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 rotary cleaning unit 341 rotates by receiving power from the first mop driving motor 371, the first mop 351 may also rotate. When the second rotary cleaning unit 342 rotates by receiving power from the second mop driving motor 372, the second mop 352 may also rotate.

At the same time, in this embodiment, the cleaning module 300 may further include a light-emitting module 360.

The light emitting module 360 can emit light to a position in front of the cleaning module 300 and allow the user to identify debris or microorganisms present in front of the cleaning module 300.

The light-emitting module 360 may be disposed on the front side of the module housing 310. For example, the light-emitting module 360 may be disposed on the front surface of the lower housing 311. A plurality of light-emitting modules 360 may be disposed, and the plurality of light-emitting modules 360 may be disposed in the left and right directions. In this case, the light-emitting module 360 may be disposed behind the cooling air inlet 317. With this arrangement, the light-emitting module 360 may be cooled by the air introduced from the cooling air inlet 317.

At the same time, the light-emitting module 360 may include: a light-emitting element; and a diffusion plate.

The light-emitting element may emit light to a position in front of or below the cleaning module. For example, the light-emitting element may include a plurality of LEDs. 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 operates, the user can identify whether debris or microorganisms are present in the position in front of the cleaning module 300. In addition, the light-emitting element can disinfect or eliminate debris or microorganisms present in the position in front of the cleaning module 300, thereby improving hygiene.

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

Meanwhile, the cleaning module 300 may further include a mop drive motor 370 configured to provide power for rotating the mop 350 and the cleaning unit 340.

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

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

At the same time, the first mop driving motor 371 and the second mop driving motor 372 can be arranged on the module housing 310 and spaced apart from each other in the left-right direction. In addition, the first mop driving motor 371 and the second mop driving motor 372 can be located behind the air inlet 313a.

The mop drive motor 370 may be disposed in the module housing 310. For example, the mop drive motor 370 may be located on the upper side of the lower housing 311 and covered by the upper housing 312. That is, the mop drive motor 370 may be located between the lower housing 311 and the upper housing 312.

At the same time, the cleaning module 300 includes a connecting tube 380, which is coupled to the vacuum cleaner body 100 or the extension tube 200.

The connecting tube 380 may include: a first connecting tube 381 connected to one end of the flow path forming portion 313; a second connecting tube 382 rotatably connected to the first connecting tube 381; and a guide tube configured to allow the internal spaces of the first connecting tube 381 and the second connecting tube 382 to communicate with each other.

The first connecting tube 381 has a tubular shape. One axial end of the first connecting tube 381 can be connected to one end of the flow path forming portion 313, and the other axial end of the first connecting tube 381 can be rotatably coupled to the second connecting tube 382. In this case, the first connecting tube 381 has a shape in which a portion of its outer peripheral surface is cut off. The first connecting tube 381 can be arranged so that the cutout portion points upward to the second connecting tube 382. Through this configuration, in a state where the cleaning module 300 is placed on the ground, the angle of the second connecting tube 382 relative to the ground can be changed by the movement of the user's hand. That is, the first connecting tube 381 and the second connecting tube 382 can be used as a joint capable of adjusting the angle of the cleaning module 300 and the angle of the vacuum cleaner body 100.

The second connecting tube 382 has a tubular shape. One axial end of the second connecting tube 382 is rotatably coupled to the first connecting tube 381, and the other axial end of the second connecting tube 382 is detachably coupled as the vacuum cleaner body 100 or the extension tube 200 is inserted into the other axial end of the second connecting tube 382.

Meanwhile, in this embodiment, the second connecting tube 382 may be coupled to the auxiliary battery housing 400. Specifically, the second connecting tube 382 may be coupled to the auxiliary battery housing 400 while penetrating the auxiliary battery housing 400. Meanwhile, although not shown in the figure, a snap-fit protrusion may be provided on the second connecting tube 382, and the connecting tube fixing portion 423 of the auxiliary battery housing 400 may be coupled to the snap-fit protrusion.

At the same time, wires may be embedded in the first connecting tube 381 and the second connecting tube 382, respectively, and the wires embedded in the first connecting tube 381 and the wires embedded in the second connecting tube 382 may be electrically connected to each other. Through this configuration, current applied from the battery 190 or the auxiliary battery 500 of the vacuum cleaner body 100 may be transmitted to the cleaning module 300.

At the same time, the guide pipe may connect the inner space of the first connecting pipe 381 and the inner space of the second connecting pipe 382. The guide pipe may have a flow path formed therein so that the air sucked into the cleaning module 300 flows to the extension pipe 200 and/or the vacuum cleaner body 100. In this case, the guide pipe may be deformed together with the first connecting pipe 381 and the second connecting pipe 382 as the first connecting pipe 381 and the second connecting pipe 382 rotate. For example, the guide pipe may be provided in the form of a corrugated pipe (corrugated pipe).

At the same time, the second connecting tube 382 may have an extension tube separation button 384. Based on the state that the second connecting tube 382 stands vertically to the ground, the extension tube separation button 384 may be set on the front side of the second connecting tube 382. Alternatively, the extension tube separation button 384 may be set on the upper side of the second connecting tube 382 when the second connecting tube 382 is parallel to the ground or tilted at a predetermined angle relative to the ground.

The extension tube detach button 384 may be coupled to the extension tube 200 by hooking. When an external force is applied, the extension tube detach button 384 may be separated from the extension tube 200. For example, the extension tube detach button 384 may be provided in the form of a thin and long plate, and a hook may be provided at one end (front end) of the extension tube detach button 384. In addition, a hinge portion is provided on a central portion of the extension tube detach button 384 so that the extension tube detach button 384 may be hinged to the second connecting tube 382. In this case, a torsion spring may be provided on the hinge portion and elastically support the coupling between the extension tube detach button 384 and the extension tube 200. In addition, the button portion may also be provided at the other end (rear end) of the extension tube separation button 384, and guide the user to press the position of the extension tube separation button 384. Through this configuration, the hook of the extension tube separation button 384 can be coupled to the extension tube 200 through hook engagement. When the user presses the button portion, the button portion rotates around the hinge portion, so that the extension tube separation button 384 can be separated from the extension tube 200.

In addition, the second connecting tube 382 may have a supporting protrusion 385. Based on the state that the second connecting tube 382 stands vertically to the ground, the supporting protrusion 385 may be arranged at the rear side of the second connecting tube 382. Alternatively, the supporting protrusion 385 may be arranged at the lower side of the second connecting tube 382 when the second connecting tube 382 is parallel to the ground or tilted at a predetermined angle relative to the ground.

The supporting protrusion 385 includes: a protruding portion; and a supporting portion. The protruding portion may protrude from the outer peripheral surface of the second connecting tube 382. The supporting portion may have a plate shape perpendicular to the protruding portion.

When the vacuum cleaner body 100 is placed on the ground (floor surface), the support portion can contact the ground and support the connecting tube 380. Through this configuration, when the vacuum cleaner 1 is placed on the floor surface, the connecting tube 380 and/or the extension tube 200 can be stably supported, which makes it possible to prevent damage to the connecting tube 380 and/or the extension tube 200.

At the same time, in this embodiment, the support protrusion 385 can be inserted into the guide hole 422 of the auxiliary battery case 400. Through this configuration, the coupling position of the connecting tube 380 and the auxiliary battery case 400 can be guided, and the auxiliary battery case 400 can be stably fixed to the connecting tube 380.

Meanwhile, the cleaning module 300 may include a printed circuit board 390 on which a module control unit (not shown) configured to control the cleaning module 300 is disposed. Current may be applied to the printed circuit board 390, and a communication line may be disposed on the printed circuit board 390. In this case, the printed circuit board 390 may be cooled by air introduced into the cooling air inlet 317 and discharged to the cooling air discharge port 318.

Meanwhile, the module housing 310 may further include a first operating portion 391 configured to adjust the amount of water discharged from the water tank 320. For example, the first operating portion 391 may be located at the rear side of the module housing 310.

The user can operate the first operating part 391. The user can operate the first operating part 391 to allow the water tank 320 to drain or not drain.

Alternatively, the first operating part 391 can adjust the amount of water to be discharged from the water tank 320. For example, the user can operate the first operating part 391 so that a first amount of water is discharged from the water tank 320 per unit time, or a second amount of water greater than the first amount of water is discharged per unit time.

The first operating portion 391 may be disposed on the module housing 310 and configured to pivot in the left-right direction. According to an embodiment, the first operating portion 391 may pivot in the upward/downward direction.

For example, when the first operating part 391 is in the neutral position, the water discharge amount is 0. When the first operating part 391 is pushed to the left and the first operating part 391 pivots to the left, a first amount of water per unit time may be discharged from the water tank 320. In addition, when the first operating part 391 is pushed to the right and the first operating part 391 pivots to the right, a second amount of water per unit time may be discharged from the water tank 320.

Meanwhile, the module housing 310 may further include a second operating portion 392 configured to adjust the phase of the moisture discharged from the steam generator 336. For example, the second operating portion 392 may be located at the rear side of the module housing 310.

The user can adjust the second operating part 392. Since the user can adjust the second operating part 392, water or steam (water vapor) can be discharged from the steam generator 336 to the mop 350.

The second operating portion 392 may be rotatably disposed on the module housing 310. For example, the second operating portion 392 may be a rotary knob (dial).

For example, when the second operating part 392 rotates and indicates the first position, the steam generator 336 does not heat the water and can discharge the room temperature water to the mop 350. In addition, when the second operating part 392 rotates and indicates the second position different from the first position, the steam generator 336 can heat the water and can discharge the heated water to the mop 350. In addition, when the second operating part 392 rotates and indicates the third position different from the first position and the second position, the steam generator 336 changes the phase of the water into steam (water vapor) by heating the water, and then discharges the steam to the mop 350.

The auxiliary battery housing 400 may be detachably coupled to the cleaning module 300, and the auxiliary battery 500 may be detachably coupled to the auxiliary battery housing 400. Specifically, the auxiliary battery housing 400 may be coupled to the connecting tube 380 of the cleaning module 300 and accommodate the auxiliary battery 500, so that the auxiliary battery 500 is detachable. In a state where the auxiliary battery housing 400 is coupled to the cleaning module 300, the auxiliary battery housing 400 may be disposed between the extension tube 200 and the cleaning module 300.

The auxiliary battery housing 400 may include: an auxiliary battery storage portion 410; a coupling portion 420; and a power connection portion (not shown).

The auxiliary battery 500 may be detachably coupled to the auxiliary battery receiving portion 410. The auxiliary battery 500 may be detachably received in the auxiliary battery receiving portion 410.

Specifically, the auxiliary battery storage part 410 may include: a storage part body 411; an auxiliary battery storage slot 412; a terminal 413; a snap-on protrusion 414; and a fastening hole 415.

In this case, the auxiliary battery storage tank 412 may be formed in the storage body 411, and the terminal 413 may be disposed in the storage body 411. In addition, the engaging protrusion 414 and the fastening hole 415 may be formed on opposite sides of the storage body 411.

The housing body 411 may define the appearance of the auxiliary battery case 400 and accommodate the auxiliary battery 500 therein. For example, the housing body 411 may have a shape similar to a quadrangular prism, and the four edges of the housing body 411 may be curved. In addition, the housing body 411 is opened at one axial end thereof so that the auxiliary battery 500 may be accommodated in the housing body 411. The other axial end of the housing body 411 may have a width that gradually decreases based on the left-right direction, so that the other axial end of the housing body 411 is connected to the coupling portion 420. Through this configuration, the housing body 411 may accommodate the auxiliary battery 500 while minimizing the overall volume and weight.

The auxiliary battery storage tank 412 can accommodate the auxiliary battery 500. The auxiliary battery storage tank 412 can have a shape corresponding to the shape of the auxiliary battery body 510 so that the auxiliary battery body 510 can be inserted into the auxiliary battery storage tank 412. For example, the diameter of the auxiliary battery storage tank 412 based on the front/rear direction can be equal to or greater than the diameter of the battery body 510 based on the front/rear direction. In addition, the diameter of the auxiliary battery storage tank 412 based on the left/right direction can be equal to or greater than the diameter of the battery body 510 based on the left/right direction. In addition, the curvature of the side wall of the auxiliary battery storage tank 412 can be equal to the curvature of the outer surface of the battery body 510.

Meanwhile, in a state where the auxiliary battery housing 400 is coupled to the connecting tube 380, the auxiliary battery receiving groove 412 may have a side wall having an inclined surface inclined at a predetermined angle. In this case, the entrance of the auxiliary battery receiving groove 412 into which the auxiliary battery 500 is inserted may be opened to be inclined upward at a predetermined angle relative to the ground.

Therefore, the auxiliary battery 500 can be tilted downward and inserted into the auxiliary battery housing 400 and coupled to the auxiliary battery housing 400. Specifically, the direction in which the auxiliary battery receiving groove 412 is formed can have an angle of more than 0 degrees and less than 90 degrees relative to the axial direction of the extension tube 200. For example, the imaginary extension line penetrating the auxiliary battery receiving groove 412 can be parallel to the imaginary extension line penetrating the internal flow path of the extension tube 200, or intersect the imaginary extension line penetrating the internal flow path of the extension tube 200 at an angle less than 90 degrees. That is, the direction in which the auxiliary battery 500 is inserted can have an angle of more than 0 degrees and less than 90 degrees relative to the longitudinal direction of the extension tube 200.

The terminal 413 may be disposed at the lower end of the secondary battery receiving slot 412. That is, the terminal 413 may be disposed in the secondary battery receiving slot 412 and disposed at a position farthest from the entrance for inserting the secondary battery 500. Through this configuration, when the secondary battery 500 is coupled to the secondary battery receiving slot 412, the terminal disposed on the electrical connection portion 540 of the secondary battery 500 may contact the terminal 413.

The engaging protrusion 414 may be coupled to the secondary battery 500 by hooking. The engaging protrusion 414 may be formed on one side of the accommodating portion main body 411 based on the left-right direction. The first coupling button 520 of the secondary battery 500 may be coupled to the engaging protrusion 414. In this case, the first button portion 521 may be caught and supported by the engaging protrusion 414, and the first hook 522 may be coupled to the engaging protrusion 414 by hooking.

The fastening hole 415 may be coupled to the auxiliary battery 500 by hooking. The fastening hole 415 may be formed on the other side of the accommodating portion main body 411 based on the left-right direction. The second coupling button 530 of the auxiliary battery 500 may be coupled to the fastening hole 415. In this case, the second hook 532 may be coupled to the fastening hole 415 by hooking.

Therefore, when the secondary battery 500 is inserted into the secondary battery receiving slot 412, the engaging protrusion 414 and the fastening hole 415 can be coupled to the secondary battery 500 through hooking, thereby preventing the secondary battery 500 from being separated.

The coupling portion 420 can be coupled to the cleaning module 300.

Specifically, the coupling part 420 includes: a coupling part body 421; a guide hole 422; and a connecting tube fixing hook 423.

The connecting tube 380 of the cleaning module 300 may be coupled to the coupling part body 421 while penetrating the coupling part body 421. For example, the coupling part body 421 may have a tubular shape. A through hole 421a may be formed in the coupling part body 421 so that the connecting tube 380 is coupled to the coupling part body 421 while penetrating the through hole 421a. In this case, the inner diameter of the coupling part body 421 may be equal to or greater than the outer diameter of the second connecting tube 382. With this configuration, the second connecting tube 382 may be penetratingly accommodated in the coupling part body 421.

The guide hole 422 may be formed in the coupling portion body 421 and provided in the form of a long hole along the axial direction of the coupling portion body 421. The guide hole 422 may accommodate the support protrusion 385 of the connecting tube 380. Therefore, when the second connecting tube 382 is coupled to the coupling portion 420, the support protrusion 385 may move along the guide hole 422, and the support protrusion 385 penetrates the guide hole 422 and is exposed to the outside. Through this configuration, the guide hole 422 may guide the coupling between the connecting tube 380 and the coupling portion 420.

The connecting tube fixing portion 423 may be disposed on the coupling portion main body 421 and coupled to the connecting tube 380 by hooking. When an external force is applied, the connecting tube fixing portion 423 may be separated from the connecting tube 380. For example, the connecting tube fixing portion 423 may be provided in the form of a slender plate, and a hook may be provided at one end of the connecting tube fixing portion 423. In addition, a hinge portion may be provided on a central portion of the connecting tube fixing portion 423 so that the connecting tube fixing portion 423 may be hinged to the coupling portion main body 421. In this case, a torsion spring may be provided on the hinge portion and elastically support the connection between the connecting tube fixing portion 423 and the connecting tube 380. In addition, a button portion may also be provided at the other end of the connecting tube fixing portion 423 to guide the user to press the position of the button portion. With this configuration, the hook of the connecting tube fixing portion 423 can be coupled to the second connecting tube 382 through hook engagement. When the user presses the button portion, the connecting tube fixing portion 423 can rotate around the hinge portion and separate from the second connecting tube 382.

The connecting tube fixing portion 423 may be coupled to the coupling portion body 421. Specifically, the connecting tube fixing portion 423 may be hinged to the side surface of the coupling portion body 421. For example, the hinge portion of the connecting tube fixing portion 423 may be coupled to the outer peripheral surface of the coupling portion body 421, and a hook through hole may be formed in the coupling portion body 421 so that the hook of the coupling portion body 421 may pass through the hook through hole. Through this configuration, when the second connecting tube 382 is inserted and coupled to the coupling portion body 421, the hook of the connecting tube fixing portion 423 may be fastened to the second connecting tube 382 and fix the coupling between the coupling portion 420 and the connecting tube 380.

Meanwhile, in this embodiment, the auxiliary battery receiving portion 410 may be disposed farther from the floor surface than the coupling portion 420.

That is, when the vacuum cleaner body 100 is placed on the floor surface in a state where the auxiliary battery 500 is coupled to the auxiliary battery housing 400 and the auxiliary battery housing 400 is coupled to the cleaning module 300, at least a portion of the extension tube 200 may be disposed closer to the floor surface than the auxiliary battery 500.

In addition, when the cleaning module 300 is placed on the floor surface in a state where the auxiliary battery 500 is coupled to the auxiliary battery housing 400 and the auxiliary battery housing 400 is coupled to the cleaning module 300, at least a portion of the auxiliary battery 500 may be disposed farther from the floor surface than the connecting tube 380. For example, the upper end of the auxiliary battery 500 may be disposed farther from the floor surface than the upper end of the connecting tube 380.

In addition, the auxiliary battery 500 may be disposed farther from the floor than a portion where the extension tube 200 and the cleaning module 300 contact each other in a state where the extension tube 200 is coupled with the cleaning module 300.

Through this configuration, when the user stands the extension tube 200 almost vertically to the cleaning module 300, the extension tube 200 and the vacuum cleaner body 100 can maintain a self-standing effect of standing vertically to the ground.

At the same time, the power connection part (not shown) can electrically connect the auxiliary battery 500 and the cleaning module 300. For example, the power connection part (not shown) can include two or more wires and connect the wires provided in the cleaning module 300 to the terminal 413 provided in the auxiliary battery accommodating part 410. Through this configuration, the auxiliary battery 500 can supply power to the cleaning module 300.

In addition, the power connection part (not shown) can electrically connect the auxiliary battery 500 and the battery 190. In this case, the power connection part (not shown) can be configured to be a separate circuit provided on the auxiliary battery housing 400. Of course, the power connection part (not shown) can be provided on the printed circuit board 390.

For example, the power connection portion (not shown) can connect the auxiliary battery 500 and the battery 190 in series. Through this configuration, the auxiliary battery 500 can be connected in series with the battery 190 and supply power to the cleaning module 300.

Therefore, when high-voltage power is needed, the vacuum cleaner 1 according to the present invention can connect the auxiliary battery 500 in series with the battery 190 and supply the high-voltage power to the cleaning module 300.

As another example, the power connection portion (not shown) can connect the auxiliary battery 500 and the battery 190 in parallel. Through this configuration, the auxiliary battery 500 can be connected in parallel with the battery 190 and supply power to the cleaning module 300.

Therefore, when a large capacity of electricity is required, the vacuum cleaner 1 according to the present invention can connect the auxiliary battery 500 in parallel with the battery 190 and supply the large capacity of electricity to the cleaning module 300.

At the same time, in the present invention, the power connection part (not shown) can switch the connection between the series connection between the auxiliary battery 500 and the battery 190 and the parallel connection between the auxiliary battery 500 and the battery 190. Specifically, the power connection part (not shown) can change the electrical connection between the auxiliary battery 500, the battery 190 and the cleaning module 300.

For example, the power connection part (not shown) can electrically connect the auxiliary battery 500 and the battery 190, and electrically connect the auxiliary battery 500 and the cleaning module 300, thereby connecting the auxiliary battery 500 and the battery 190 in series. In addition, the power connection part (not shown) can electrically connect the battery 190 and the cleaning module 300, and electrically connect the auxiliary battery 500 and the cleaning module 300, thereby connecting the auxiliary battery 500 and the battery 190 in parallel. In addition, the power connection part (not shown) can change the electrical connection between the battery 190 and the cleaning module 300 to the electrical connection between the battery 190 and the auxiliary battery 500 by using a switch or the like.

At the same time, according to an embodiment, the power connection portion (not shown) can connect the auxiliary battery 500 and the steam generator 336. In this case, the battery 190 can supply power to the components of the vacuum cleaner 1 including the suction motor 140 but not including the steam generator 336, and the auxiliary battery 500 can only supply power to the steam generator 336. Through this configuration, the auxiliary battery 500 can directly supply power to the steam generator 336.

Therefore, the auxiliary battery 500 can stably supply power to the steam generator 336 which requires a relatively large amount of power in a short time.

The auxiliary battery 500 can supply power to the vacuum cleaner body 100 or the cleaning module 300. The auxiliary battery 500 can include: an auxiliary battery body 510; a first coupling button 520; a second coupling button 530; and an electrical connection portion 540.

The auxiliary battery body 510 may supply power to the vacuum cleaner body 100 or the cleaning module 300. The auxiliary battery body 510 may define the outer shape of the auxiliary battery 500 and store electric energy therein. For example, the auxiliary battery body 510 may be a secondary battery.

The first coupling button 520 may be disposed on one side of the auxiliary battery body 510. The first coupling button 520 may be coupled to the snap-fit protrusion 414 of the auxiliary battery housing 400 by hooking. For example, the first coupling button 520 may include: a first button portion 521; and a first hook 522. One end of the first button portion 521 may be connected to one side of the auxiliary battery body 510. In this case, the first button portion 521 may be made of a material having elasticity. In addition, the first hook 522 may be connected to the other end of the first button portion 521 and protrude in a direction away from the auxiliary battery body 510. The first hook 522 may be coupled to the snap-fit protrusion 414 by hooking.

Through this configuration, when the secondary battery 500 is coupled to the secondary battery case 400, the first hook 522 can be coupled to the engaging protrusion 414 through engagement. In addition, the user can separate the secondary battery 500 from the secondary battery case 400 by pulling the secondary battery 500 while pressing the first button portion 521.

The second coupling button 530 may be disposed on the other side of the auxiliary battery body 510. The second coupling button 530 may be coupled to the fastening hole 415 of the auxiliary battery housing 400 by hooking. For example, the second coupling button 530 may include: a second button portion 531; and a second hook 532. One end of the second button portion 531 may be connected to the other side of the auxiliary battery body 510. In this case, the second button portion 531 may be made of a material having elasticity. In addition, the second hook 532 may be connected to the other end of the second button portion 531 and protrude in a direction away from the auxiliary battery body 510. The second hook 532 may be coupled to the fastening hole 415 by hooking.

Through this configuration, when the secondary battery 500 is coupled to the secondary battery case 400, the second hook 532 can be coupled to the fastening hole 415 through hook engagement. In addition, the user can separate the secondary battery 500 from the secondary battery case 400 by pulling the secondary battery 500 while pressing the second button portion 531.

The electrical connection part 540 may be disposed at the lower side of the auxiliary battery body 510. When the auxiliary battery 500 is coupled to the auxiliary battery housing 400, the electrical connection part 540 may be electrically connected to the terminal 413 of the auxiliary battery housing 400. Through this configuration, when the auxiliary battery 500 is coupled to the auxiliary battery housing 400, the power stored in the auxiliary battery 500 may be supplied to the vacuum cleaner body 100 or the cleaning module 300.

Meanwhile, FIG. 13 and FIG. 14 are views for explaining the coupling state of the cleaning module 300 and the auxiliary battery housing 400 of the vacuum cleaner according to the second embodiment of the present invention.

The cleaning module and auxiliary battery housing of the vacuum cleaner according to the second embodiment of the present invention will be described below with reference to Figures 13 and 14.

In order to avoid repeated description, in addition to the components specifically described in this embodiment, the description of the configuration and effect of the vacuum cleaner according to the embodiment of the present invention can be applied.

In the present embodiment, the guide hole 1422 may be formed in the coupling portion body 1421 and provided in the form of a long hole along the axial direction of the coupling portion body 1421. The extension tube separation button 1384 of the connecting tube 1380 may be accommodated in the guide hole 1422. Therefore, when the connecting tube 1380 is coupled to the coupling portion 1420, the extension tube separation button 1384 may move along the guide hole 1422, and the extension tube separation button 1384 may penetrate the guide hole 1422 and be exposed to the outside. Through this configuration, the guide hole 1422 may guide the coupling between the connecting tube 1380 and the coupling portion 1420.

Meanwhile, in the present embodiment, the coupling portion 1420 may further include a supporting rib 1424. At least one supporting rib 1424 may protrude from the coupling portion body 1421. In addition, the supporting rib 1424 may be connected to the receiving portion body 1411. That is, the supporting rib 1424 may connect the coupling portion body 1421 and the receiving portion body 1411.

Through this configuration, the supporting rib 1424 can support the connection between the coupling portion body 1421 and the receiving portion body 1411.

When the auxiliary battery housing 1400 is placed on the ground in a state where the auxiliary battery housing 1400 is coupled to the cleaning module 1300, the supporting ribs 1424 can support the connection between the coupling portion body 1421 and the accommodating portion body 1411, thereby preventing damage to the auxiliary battery housing 1400.

Meanwhile, in this embodiment, the auxiliary battery receiving portion 1410 may be arranged closer to the floor surface than the coupling portion 1420.

That is, when the cleaning module 1300 and the vacuum cleaner body 100 are placed on the floor surface in a state where the auxiliary battery 1500 is coupled to the auxiliary battery housing 1400 and the auxiliary battery housing 1400 is coupled to the cleaning module 1300, at least a portion of the auxiliary battery 1500 may be disposed closer to the floor surface than the extension tube 200.

In addition, when the cleaning module 1300 is placed on the floor surface, at least a portion of the auxiliary battery 1500 may be disposed closer to the floor surface than the connecting tube 1380. For example, the lower end of the auxiliary battery 1500 may be disposed closer to the floor surface than the lower end of the connecting tube 1380.

In addition, in a state where the extension tube 200 is coupled to the cleaning module 1300, the auxiliary battery 1500 may be disposed closer to the floor than a portion where the extension tube 200 and the cleaning module 1300 contact each other.

Through this configuration, the volume of the cleaning module 1300 based on the up-down direction is reduced in a state where the auxiliary battery 1500 is installed. Therefore, it is possible to advantageously clean a space such as the space under the sofa, which limits the height at which the cleaning module 1300 can enter the space.

In addition, the overall center of gravity of the cleaning module 1300 is lowered, which makes it easier for the user to perform operations such as changing direction.

FIG. 17 is a view for explaining a state in which the auxiliary battery housing according to the third embodiment of the present invention is coupled to the extension tube of the vacuum cleaner.

At the same time, the auxiliary battery housing of the vacuum cleaner according to the third embodiment of the present invention will be described below with reference to FIG. 17.

In order to avoid repeated description, in addition to the components specifically described in this embodiment, the description of the configuration and effect of the vacuum cleaner according to the embodiment of the present invention can be applied.

In this embodiment, the auxiliary battery housing 2400 may be coupled to the extension tube 2200. That is, the coupling portion 2420 of the auxiliary battery housing 2400 may be coupled to the extension tube 2200.

Specifically, the coupling part 2420 includes: a coupling part body 2421; and a connecting tube fixing hook 2423.

The extension tube 2200 may be penetratingly coupled to the coupling body 2421. For example, the coupling body 2421 may have a tubular shape. A through hole 2421a may be formed in the coupling body 2421 so that the extension tube 2200 is coupled to the coupling body 2421 while penetrating the through hole 2421a. In this case, the inner diameter of the coupling body 2421 may be equal to or greater than the outer diameter of the extension tube 2200. With this configuration, the extension tube 2200 may be penetratingly accommodated in the coupling body 2421.

FIG. 18 is a view for explaining the state in which the auxiliary battery housing of the fourth embodiment of the present invention is coupled to the vacuum cleaner body of the vacuum cleaner.

At the same time, the vacuum cleaner body and auxiliary battery housing of the vacuum cleaner according to the fourth embodiment of the present invention will be described below with reference to FIG. 18.

In order to avoid repeated description, in addition to the components specifically described in this embodiment, the description of the configuration and effect of the vacuum cleaner according to the embodiment of the present invention can be applied.

In this embodiment, the auxiliary battery housing 3400 may be detachably coupled to the battery housing 3180 of the vacuum cleaner body 3100. For example, the auxiliary battery housing 3400 may be detachably coupled to the lower surface of the battery housing 3180.

The auxiliary battery housing 3400 can be disposed on the lower side of the battery 3190 when the battery 3190 is coupled to the battery housing 3180.

FIG. 19 is a view for explaining a state in which the auxiliary battery housing according to the fifth embodiment of the present invention is coupled to the vacuum cleaner body of the vacuum cleaner.

At the same time, the vacuum cleaner body and auxiliary battery housing of the vacuum cleaner according to the fifth embodiment of the present invention will be described below with reference to FIG. 19.

The present invention is described above in conjunction with specific embodiments, but these specific embodiments are only used to specifically illustrate the present invention, and the present invention is not limited to these specific embodiments. Obviously, those who are familiar with this technology in this technical field can modify or change the present invention without departing from the technical spirit of the present invention.
