Description

Technical Field

[0001] The present invention relates to a vacuum cleaner, and more particularly to a vacuum cleaner capable of detachably attaching a cleaning module that sucks or wipes dust or foreign matter in a cleaning target area by spouting water to a rag. Background Art

[0002] A vacuum cleaner is a device that cleans the area by sucking in or wiping away dust or foreign matter.

[0003] Such vacuum cleaners may be divided into manual vacuum cleaners in which a user directly moves the vacuum cleaner and performs cleaning, and automatic vacuum cleaners that autonomously travel and perform cleaning.

[0004] A handheld vacuum cleaner is a vacuum cleaner that maximizes portability. Although it is lightweight, it is short and requires squatting to clean, so the cleaning area is limited. Therefore, it is used to clean local places such as desks, sofas, or cars.

[0005] A stick vacuum cleaner can be used while standing, so it can be cleaned without bending over. Therefore, it is convenient to move and clean in a wide area. Compared with a handheld vacuum cleaner that cleans a narrow space, a stick vacuum cleaner can clean a wider space and can clean high places that cannot be reached by hands. In recent years, stick vacuum cleaners have been provided in a modular form to actively change the type of vacuum cleaner and use it for various objects.

[0006] There are two main ways to clean a floor: dry cleaning and wet cleaning. Dry cleaning involves sweeping or sucking up dust, and existing vacuum cleaners fall into this category. Wet cleaning involves wiping dust off with a wet rag. In addition, wet cleaning involves generating and spraying high-temperature steam to sterilize and clean.

[0007] Recently, with the use of various materials in buildings, cleaning methods have also become more diverse. In the past, floors were mainly made of wood, which could not be cleaned wet, and only dry cleaning was performed. However, recently, floors are made of various materials such as steel plates and marble, so wet cleaning is also possible.

[0008] In the past, dry vacuum cleaners were used for dry cleaning, and wet vacuum cleaners were used for wet cleaning. However, it is inconvenient that two types of vacuum cleaners must be purchased to clean different types of floors. In order to solve the above problems, a method is being studied: including a main body, a dry cleaning module and a wet cleaning module, and the dry cleaning module is installed on the main body for dry cleaning, and the wet cleaning module is installed on the main body for wet cleaning.

[0009] The wet cleaning module includes a bucket for storing water, a heater for generating steam by heating water, and a rag for wiping the floor by receiving water or steam. For ease of replacement, the above-mentioned components are preferably composed of an assembly. For example, when the bucket or heater is configured in the main body, when the dry cleaning module is installed in the main body, there is a problem of inconvenience in cleaning due to unnecessary components. Therefore, considering the ease of cleaning or the ease of module replacement or space utilization, the bucket or heater is preferably configured in the wet cleaning module instead of the main body.

[0010] Korean authorized utility model KR0489070Y1 discloses a wet rag vacuum cleaner in which a main battery is provided in a cleaning module and an auxiliary battery is detachably coupled to an extension tube.

[0011] However, the wet rag vacuum cleaner cannot suck in dust, and most of the power is used for the rotation of the rag, so combining the auxiliary battery is only to simply increase the use time of the vacuum cleaner.

[0012] Furthermore, when foreign matter is pressed against the floor, in a vacuum cleaner that wipes the floor surface by rotating a rag as described above, the foreign matter may still remain even if the rag that has absorbed water is rotated to wipe the floor.

[0013] Furthermore, when microorganisms and the like multiply on the floor, even if a cloth soaked in water is rotated to wipe the floor, there is a limitation that the microorganisms cannot be completely sterilized.

[0014] In order to solve this problem, a method of heating the water supplied to the mop may be considered. However, if a heater that uses a large amount of electric power to heat the water is additionally mounted on the cleaning module, a large amount of electric power needs to be supplied to the cleaning module.

[0015] Korean patent KR0738478B1 shows a vacuum cleaner capable of steam cleaning and suction of dust.

[0016] The cleaner may be a combination of a steam cleaner and a vacuum cleaner, and may be configured such that power is supplied from the steam cleaner to the vacuum cleaner.

[0017] However, since the vacuum cleaner is supplied with power based on a steam cleaner that uses a large amount of power, it is necessary to receive power in a wired manner or use a large battery, and thus there is a limitation that it is difficult to apply to a handheld vacuum cleaner.

[0018] Therefore, when heating water, a large amount of electricity needs to be supplied to the cleaning module, and at the same time, the cleaning time of the entire vacuum cleaner needs to be maintained.

[0019] In addition, in the process of the user attaching and detaching the auxiliary battery as needed, it is necessary to easily and simply attach and detach the auxiliary battery. Summary of the invention

[0020] Problems to be solved by the invention

[0021] The present invention is proposed to improve the problems existing in the conventional vacuum cleaner in which a cleaning module having a steam generator is detachably coupled as described above, and its object is to provide a vacuum cleaner with an increased total battery capacity.

[0022] Another object is to provide a vacuum cleaner that improves the sterilization and foreign matter removal effects by supplying high-temperature water or steam to a rag.

[0023] Another object is to provide a vacuum cleaner that can supply extra power and is easy to operate.

[0024] Another object is to provide a vacuum cleaner capable of stably supplying electric power when a cleaning module generates steam.

[0025] Another object is to provide a vacuum cleaner in which a user can easily attach and detach an auxiliary battery.

[0026] Another object is to provide a vacuum cleaner capable of preventing interference between the auxiliary battery and the cleaning module during cleaning.

[0027] Another object is to provide a vacuum cleaner that can reduce the force required by the user's wrist or arm when the user controls the cleaning module.

[0028] Technical solutions to the problem

[0029] In order to achieve the above-mentioned objectives, the vacuum cleaner of the present invention may include: a vacuum cleaner main body, which is provided with a battery and a handle for a user to hold; a cleaning module, which can be detachably combined with the vacuum cleaner main body to clean foreign objects on the floor; an auxiliary battery cover, which can be detachably combined with the cleaning module; and an auxiliary battery, which can be detachably combined with the auxiliary battery cover to supply power to the vacuum cleaner main body or the cleaning module.

[0030] At this time, the auxiliary battery cover may include: an auxiliary battery accommodating portion, which is formed with an auxiliary battery accommodating groove for inserting the auxiliary battery; and a stopper, which can be arranged in a linear reciprocating manner in the auxiliary battery accommodating portion to prevent the auxiliary battery accommodating portion from detaching when combined with the cleaning module.

[0031] In addition, the auxiliary battery cover may include a separation button, which is disposed on the auxiliary battery receiving portion so as to be linearly reciprocatable, and moves the stopper when an external force is applied.

[0032] At this time, the separation button may include: a button portion, to which external force is applied; a protrusion, which protrudes from the button portion and extends in a direction intersecting with the length direction of the stopper; and an inclined surface, which is formed on the protrusion and is formed to form a specified angle with the extension direction of the protrusion and contacts the stopper.

[0033] At this time, the stopper can reciprocate linearly as the inclined surface moves upward.

[0034] On the other hand, the stopper may include: a hook portion contacting the cleaning module; and a moving portion connected to the hook portion and contacting the separation button.

[0035] On the other hand, the auxiliary battery cover may include a coupling portion which is protruded from the auxiliary battery receiving portion and is coupled to the cleaning module.

[0036] At this time, the coupling portion may include a first coupling portion that is protruded from the auxiliary battery receiving portion and is provided with a terminal electrically connected to the cleaning module.

[0037] In addition, the coupling portion may further include a second coupling portion that is protruded from the auxiliary battery receiving portion and connected to the first coupling portion.

[0038] At this time, in order to improve the combining force between the auxiliary battery cover and the cleaning module, the protruding height of the first combining portion may be formed to be higher than the protruding height of the second combining portion.

[0039] The hook portion may be exposed from a side of the auxiliary battery receiving portion where the second coupling portion is formed.

[0040] Therefore, the battery connecting portion of the cleaning module can be sandwiched and fixed between the second combining portion and the hook portion.

[0041] On the other hand, the cleaning module may include a connecting pipe combined with the auxiliary battery cover; the connecting pipe may include: a connecting pipe body; and a battery connecting portion, and the auxiliary battery cover is combined with the battery connecting portion along the length direction of the connecting pipe body.

[0042] Also, the connection pipe may include a hook receiving groove formed at a side wall of the battery connecting portion and receiving the stopper.

[0043] On the other hand, the direction in which the external force is applied to the separation button may be parallel to the direction in which the auxiliary battery cover is separated from the cleaning module.

[0044] Effects of the Invention

[0045] As described above, according to the vacuum cleaner of the present invention, the auxiliary battery is installed, thereby having the effect of increasing the total capacity of the battery.

[0046] In addition, high-temperature water or steam is supplied to the rag by the heater, thereby having the effect of enhancing the sterilization and foreign matter removal effects.

[0047] In addition, there is an effect that additional power can be supplied by the auxiliary battery and the operation is easy for the user.

[0048] In addition, there is an effect of being able to stably supply power when the auxiliary battery supplies extra power to the heater to cause the cleaning module to generate steam.

[0049] In addition, during the process of separating the auxiliary battery and the cleaning module, the direction in which the user presses the button and the direction in which the user pulls the auxiliary battery are made consistent, thereby achieving an effect that the user can easily separate the auxiliary battery in one action.

[0050] In addition, the auxiliary battery and the cleaning module are arranged at a predetermined distance, thereby preventing the auxiliary battery from interfering with the cleaning module during the cleaning process.

[0051] In addition, the auxiliary battery is arranged on the connection pipe of the cleaning module, so that the load of the auxiliary battery is distributed to the entire cleaning module, thereby having the effect that the user can easily operate the cleaning module.

[0077] Figure 1 A three-dimensional diagram of a vacuum cleaner according to an embodiment of the present invention is disclosed. Figure 2 A three-dimensional diagram of a vacuum cleaner body for illustrating an embodiment of the present invention is disclosed in Figure 3 A cross-sectional view of a vacuum cleaner body for illustrating an embodiment of the present invention is disclosed.

[0078] In this specification, it can be understood that the "floor surface" refers not only to the floor surface of a living room or a room, but also to a clean surface such as a carpet.

[0079] Reference Figures 1 to 3A vacuum cleaner 1 according to an embodiment of the present invention may include: a vacuum cleaner body 100 having a suction motor 140 for generating suction; a cleaning module 300 connected to the vacuum cleaner body 100, sucking in air and foreign matter from the floor surface, and used to wipe and clean the floor surface; and an extension tube 200 connecting the vacuum cleaner body 100 and the cleaning module 300.

[0080] Next, the structure of the cleaner body 100 will be described.

[0081] On the other hand, in one embodiment of the present invention, the direction may be defined based on the bottom surface (lower side) of the dust collecting bucket 170 and the battery housing 180 placed on the ground.

[0082] At this time, the front may refer to the direction in which the suction unit 120 is arranged with the suction motor 140 as the reference, and the rear may refer to the direction in which the handle 160 is arranged. Moreover, the direction arranged on the right side may be referred to as the right side, and the direction arranged on the left side may be referred to as the left side, based on the suction unit 120 viewed from the suction motor 140. In addition, in one embodiment of the present invention, the upper side and the lower side may be defined in a direction perpendicular to the ground with the bottom surface (lower side) of the dust collecting bucket 170 and the battery housing 180 placed on the ground as the reference.

[0083] The vacuum cleaner 1 may include a vacuum cleaner body 100. The vacuum cleaner body 100 may include a body housing 110, a suction unit 120, a dust separation unit 130, a suction motor 140, an air discharge cover 150, a handle 160, a dust collection bucket 170, a battery housing 180, and a battery 190.

[0084] The main body cover 110 may constitute the appearance of the cleaner body 100. The main body cover 110 may provide a space capable of accommodating the suction motor 140 and a filter (not shown) inside. The main body cover 110 may be configured in a form similar to a cylinder.

[0085] The suction part 120 may protrude outward from the main housing 110. As an example, the suction part 120 may be formed in a cylindrical shape with an inner opening. The suction part 120 may be combined with the extension tube 200. The suction part 120 may provide a flow path (hereinafter, referred to as "suction flow path") through which air containing dust may flow.

[0086] The dust separator 130 is connected to the suction part 120 and is a structure that applies the principle of a dust collector using centrifugal force to separate dust sucked into the cleaner body 100 through the suction part 120. The space inside the dust separator 130 can be connected to the space inside the dust bucket 170.

[0087] For example, the dust separation unit 130 may include at least one cyclone unit capable of separating dust by cyclone flow. In addition, the space inside the dust separation unit 130 may be communicated with the suction flow path. Therefore, the air and dust sucked in via the suction unit 120 may flow in a spiral along the inner circumference of the dust separation unit 130. Therefore, a cyclone flow may be generated in the internal space of the dust separation unit 130.

[0088] The suction motor 140 can generate suction force for sucking air. The suction motor 140 can be accommodated in the main housing 110. The suction motor 140 can generate suction force by rotating. As an example, the suction motor 140 can be configured to be similar to a cylindrical shape.

[0089] The air outlet cover 150 may be disposed on one axial side of the main housing 110. A filter for filtering air may be accommodated in the air outlet cover 150. As an example, a high efficiency air (HEPA) filter may be accommodated in the air outlet cover 150.

[0090] The handle 160 can be held by the user. The handle 160 can be arranged behind the suction motor 140. As an example, the handle 160 can be formed in a cylindrical shape. Alternatively, the handle 160 can be formed in a curved cylindrical shape. The handle 160 can be arranged to form a specified angle with the main cover 110, the suction motor 140, or the dust separation unit 130.

[0091] The handle 160 may include: a gripping portion 161 formed in a columnar shape so that the user can grip it; a first extension portion connected to one end portion of the gripping portion 161 in the length direction (axial direction) and extending toward the suction motor 140; and a second extension portion connected to the other end portion of the gripping portion 161 in the length direction (axial direction) and extending toward the dust collecting container 170.

[0092] The top surface of the handle 160 may form a portion of the appearance of the top surface of the cleaner 1 .

[0093] The operation unit 165 may be disposed on the handle 160. The operation unit 165 may be disposed on an inclined surface formed in an upper region of the handle 160. The user may input an operation or stop command of the vacuum cleaner 1 through the operation unit 165.

[0094] The dust collecting bucket 170 may be in communication with the dust separating portion 130. The dust collecting bucket 170 may store the dust separated from the dust separating portion 130.

[0095] The dust bucket 170 may include a dust bucket body 171 .

[0096] The dust collecting container body 171 may provide a space capable of storing the dust separated by the dust separating unit 130. As an example, the dust collecting container body 171 may be formed similar to a cylindrical shape.

[0097] As an example, the dust collecting bucket body 171 can be set so that the lower side can be opened. In this case, a discharge cover 172 is provided on the lower side of the dust collecting bucket body 171, so that the lower side of the dust collecting bucket body 171 can be selectively opened.

[0098] On the other hand, according to an embodiment, the dust bucket 170 may further include a dust bucket compression rod 173 and a compression member 174 .

[0099] The dust bucket compression rod 173 can be configured outside the dust bucket 170 or the dust separation unit 130. The dust bucket compression rod 173 can be configured to move up and down outside the dust bucket 170 or the dust separation unit 130. The dust bucket compression rod 173 can be connected to the compression member 174. When the dust bucket compression rod 173 moves downward under the action of an external force, the compression member 174 can also move downward together. Thus, user convenience can be provided. The compression member 174 and the dust bucket compression rod 173 can be reset to the original position under the action of an elastic member (not shown). Specifically, when the external force applied to the dust bucket compression rod 173 is removed, the elastic member can cause the dust bucket compression rod 173 and the compression member 174 to move upward.

[0100] The compression member 174 may be disposed inside the dust bucket body 171. The compression member 174 may move in the internal space of the dust bucket body 171. Specifically, the compression member 174 may move up and down in the dust bucket body 171. Thus, the compression member may compress the dust in the dust bucket body 171 downward. In addition, when the discharge cover 172 is separated from the dust bucket body 171 and the lower part of the dust bucket 170 is open, the compression member 174 may move from the upper part of the dust bucket 170 to the lower part and remove foreign matter such as residual dust in the dust bucket 170. Thus, by preventing the residual dust from remaining in the dust bucket 170, the suction force of the vacuum cleaner can be improved. Furthermore, by preventing the residual dust from remaining in the dust bucket 170, the odor generated by the residual matter can be removed.

[0101] The battery cover 180 may accommodate the battery 190 . The battery cover 180 may be disposed on the lower side of the handle 160 .

[0102] As an example, the battery cover 180 may be in the shape of a hexahedron with an open bottom. The back of the battery cover 180 may be connected to the handle 160. In this case, the battery cover 180 may include a receiving portion open downward. With such a configuration, the battery 190 may be loaded and unloaded through the receiving portion of the battery cover 180.

[0103] As another example, the battery cover 180 may be integrally formed with the battery 190 accommodated therein.

[0104] The battery 190 is a component for supplying power to the vacuum cleaner 1. Specifically, the battery 190 can supply power to the suction motor 140, and can supply power to the electronic circuit and electronic components through the wires built into the vacuum cleaner 1. In addition, the battery 190 can supply power to the cleaning module 300.

[0105] When the battery 190 is combined with the battery cover 180, the bottom surface of the battery 190 can be exposed to the outside. When the vacuum cleaner 1 is placed on the floor, the battery 190 can be placed on the floor, so the battery 190 can be directly separated from the battery cover 180. In addition, the bottom surface of the battery 190 is exposed to the outside and directly contacts the outside air of the battery 190, so the cooling performance of the battery 190 can be improved.

[0106] On the other hand, when the battery 190 and the battery cover 180 are fixed integrally, the structure for attaching and detaching the battery 190 and the battery cover 180 can be reduced, so the overall size of the cleaner 1 can be reduced and the weight can be reduced.

[0107] The cleaner 1 may include an extension pipe 200 .

[0108] The extension pipe 200 may be combined with the cleaner body 100 and the cleaning module 300 .

[0109] For example, the extension pipe 200 may be formed in a cylindrical shape. Therefore, the inner space of the extension pipe 200 may be communicated with the inner space of the cleaning module 300. In addition, the extension pipe 200 may be communicated with the suction flow path formed in the suction part 120 of the cleaner body 100.

[0110] When the suction motor 140 generates suction, the suction part 120 and the extension tube 200 may provide suction to the cleaning module 300. Therefore, external dust and air may flow into the cleaner body 100 through the cleaning module 300 and the extension tube 200. In addition, the dust and air flowing in through the cleaning module 300 may flow into the cleaner body 100 after passing through the extension tube 200. Furthermore, after the dust and air flowing into the cleaner body 100 and passing through the suction part 120 are separated in the dust separation part 130, the dust may be stored in the dust collecting bucket 170, and the air may be discharged to the outside through the air discharge cover 150.

[0111] On the other hand, an electric wire may be built in the extension tube 200 . Therefore, the cleaner body 100 and the cleaning module 300 may be electrically connected through the extension tube 200 .

[0112] Figures 4 to 8 A diagram is shown for illustrating a cleaning module according to an embodiment of the present invention.

[0113] Reference Figures 4 to 8The cleaning module 300 of the embodiment of the present invention may include a module cover 310 and a connecting pipe 380 movably connected to the module cover 310 .

[0114] As an example, the cleaning module 300 of this embodiment can be connected to a handheld vacuum cleaner for use.

[0115] That is, the cleaning module 300 can be detachably connected to the cleaner body 100 or the extension tube 200. Therefore, with the connection to the cleaner body 100 or the extension tube 200, the user can use the cleaning module 300 to clean the floor surface. At this time, the cleaner body 100 connected to the cleaning module 300 can separate dust in the air in a multi-cyclone manner.

[0116] The cleaning module 300 can receive power from the cleaner body 100 to operate. Specifically, the cleaning module 300 can receive power from the battery 190 of the cleaner body 100 to operate.

[0117] The cleaner body 100 connected to the cleaning module 300 includes a suction motor 140 , so that the suction force generated by the suction motor 140 acts on the cleaning module 300 , so that foreign matter and air on the floor surface can be sucked into the cleaning module 300 .

[0118] Therefore, in this embodiment, the cleaning module 300 can perform the function of sucking in foreign matter and air on the floor surface and guiding them to the vacuum cleaner 1 .

[0119] The connection pipe 380 is connected to the rear center portion of the module cover 310 and can guide the sucked air to the cleaner body 100 , but is not limited thereto.

[0120] To help understand and define the direction of this embodiment, the portion of the cleaning module 300 to which the connecting pipe 380 is connected may be referred to as the rear side (rear) of the cleaning module 300 , and the opposite side of the connecting pipe 380 may be referred to as the front side (front) of the cleaning module 300 .

[0121] In addition, the left side of the flow path forming portion 313 may be referred to as the left side of the cleaning module 300, and the right side of the flow path forming portion 313 may be referred to as the right side of the cleaning module 300, based on the observation of the suction port 313a from the connecting pipe 380. Furthermore, the direction connecting the left and right sides may be referred to as the left-right direction. The left-right direction may refer to a direction perpendicular to the front-rear direction on a horizontal plane.

[0122] In addition, based on the state in which the cleaning module 300 is placed on the floor surface, that is, the state in which the rag 350 is placed on the floor surface and can wipe the floor surface, the direction close to the floor surface can be called the lower side or downward, and the direction away from the floor surface can be called the upper side or upward.

[0123] The cleaning module 300 may further include a rotating cleaning unit 340 rotatably disposed on the lower side of the module cover 310 .

[0124] As an example, the rotary cleaning unit 340 may be provided in a pair and arranged in the left-right direction. In this case, the pair of rotary cleaning units 340 may rotate independently. As an example, the rotary cleaning unit 340 may include a first rotary cleaning unit 341 and a second rotary cleaning unit 342.

[0125] The rotary cleaning unit 340 may be combined with a rag 350 . As an example, the rag 350 may be formed in a disc shape. The rag 350 may include a first rag 351 and a second rag 352 .

[0126] When the rag 350 is placed on the floor surface, the rag 350 is in close contact with the floor surface due to the load of the cleaning module 300, so the friction between the rag 350 and the floor surface increases.

[0127] The module cover 310 forms the outer shape of the cleaning module 300 and may be formed with an air inlet 313a for inhaling air. As an example, the air inlet 313a may be formed at the bottom front end of the module cover 310. The air inlet 313a may be formed extending in the left-right direction on the module cover 310.

[0128] The module cover 310 may include a lower cover 311 and an upper cover 312 coupled to an upper side of the lower cover 311 .

[0129] The lower cover 311 is installed with a rotating cleaning unit 340 to form the outer shape of the cleaning module 300 .

[0130] A suction port 313 a may be formed in the lower cover 311 .

[0131] The lower cover 311 may be provided with a substrate installation portion, on which a printed circuit board 390 for controlling the mop driving motor 370 is installed. As an example, the substrate installation portion may be formed in a hook shape extending upward from the lower cover 311 .

[0132] The substrate setting portion may be located on one side of the flow path forming portion 313 in the lower housing 311, but is not limited thereto. As an example, the printed circuit board 390 may be disposed adjacent to the first operating portion 391 and the second operating portion 392. Therefore, the switch provided on the printed circuit board 390 can sense the operation of the first operating portion 391 and the second operating portion 392.

[0133] A nozzle hole (not shown) for passing the diffuser 337 may be formed in the lower cover 311. Water or steam (water vapor) passing through the heat generator 336 and the diffuser 337 may be supplied to the rag 350 through the nozzle hole (not shown).

[0134] The upper cover 312 covers the upper side of the lower cover 311 to form the outer shape of the cleaning module 300 of the present invention.

[0135] In addition, the module cover 310 may further include a flow path forming portion 313 , which is communicated with the suction port 313 a and forms a flow path for guiding the air flowing in from the suction port 313 a to the cleaner body 100 .

[0136] The flow path forming portion 313 may be coupled to the upper central portion of the lower cover body 311 , and an end portion may be connected to the connection pipe 380 .

[0137] Therefore, by configuring the flow path forming portion 313 , the suction port 313 a can extend in a substantially straight line along the front-rear direction, so that the length of the suction port 313 a can be minimized, thereby minimizing the flow path loss in the cleaning module 300 .

[0138] The front side portion of the flow path forming portion 313 may cover the upper side of the suction port 313a. The flow path forming portion 313 may be arranged to be inclined upward as it approaches the rear side from the front end portion.

[0139] Therefore, the flow path forming portion 313 may be formed so that the height of the front portion is lower than the height of the rear portion.

[0140] According to this embodiment, since the height of the front part of the flow path forming part 313 is low, there is an advantage that the height of the front part of the overall height of the cleaning module 300 can be reduced. The lower the height of the cleaning module 300, the higher the possibility of introducing it into a narrow space under furniture or chairs for cleaning.

[0141] A block 314 is disposed on the bottom surface of the lower cover body 311. The block 314 can shield the front space where the suction port 313a is disposed and the rear space where the rag 350 is disposed, thereby blocking the moisture discharged from the rag 350 from diffusing to the suction port 313a. For example, the block 314 may include a central portion 314a and an extension portion 314b. At this time, a pair of extension portions 314b may be symmetrically connected to the two side ends with the central portion 314a as a reference. In addition, the central portion 314a is disposed behind the suction port 313a, thereby blocking the moisture from flowing to the suction port 313a side. In addition, the extension portion 314b may be formed in an arc shape to surround the circular rag 350.

[0142] A plurality of rollers for smoothly moving the cleaning module 300 may be provided on the lower side of the lower cover 311 .

[0143] As an example, in the lower cover 311, a front roller 315 may be provided in front of the rag 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 spaced apart in the left-right direction.

[0144] 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 cover 311 in a state of being configured to extend in the left-right direction.

[0145] The distance between the shaft and the front end of the lower cover body 311 is longer than the minimum distance between the rag 350 and the front end of the lower cover body 311 .

[0146] As an example, at least a portion of the rotary cleaning unit 340 may be disposed between the axis of the first roller 315 a and the axis of the second roller 315 b .

[0147] According to such a configuration, the rotary cleaning unit 340 can be brought as close to the suction port 313a as possible, and the area cleaned by the rotary cleaning unit 340 on the floor surface where the cleaning module 300 is located is increased, thereby improving the floor cleaning performance.

[0148] In the case of this embodiment, since the first roller 315 a and the second roller 315 b are combined with the lower side of the lower cover 311 , the mobility of the cleaning module 300 can be improved.

[0149] A third roller 316 may also be provided at the lower side of the lower cover 311. Therefore, the first roller 315a and the second roller 315b may support the cleaning module 300 at three points together with the third roller 316. At this time, the third roller 316 may be located behind the rag 350 to avoid interference with the rag 350.

[0150] The module cover 310 may be formed with a cooling air inlet 317 and a cooling air outlet 318 .

[0151] A cooling air inlet 317 may be formed in the lower cover 311. External air may flow into the interior of the module cover 310 through the cooling air inlet 317. In addition, the cooling air inlet 317 may be formed on the front side wall of the lower cover 311. With such a configuration, when the cleaning module 300 moves forward by the user's operation, the amount of air flowing in may be increased.

[0152] A cooling air outlet 318 may be formed in the upper cover 312. The air inside the module cover 310 may be discharged to the outside through the cooling air outlet 318. In addition, the cooling air outlet 318 may be formed on both side walls of the upper cover 312. With such a configuration, the air flowing in through the cooling air inlet 317 may be guided to pass through the rag drive motor 370 in the process of flowing toward the cooling air outlet 318, thereby having the advantage of being able to prevent the rag drive motor 370 from overheating.

[0153] Furthermore, based on the state where the lower cover 311 is placed on the floor, the cooling air outlet 318 can be arranged at a position farther from the ground than the cooling air inlet 317. With this configuration, the air heated inside the module cover 310 rises and can be efficiently discharged through the cooling air outlet 318.

[0154] The cleaning module 300 may further include a water tank 320 to be able to supply moisture to the mop 350 .

[0155] The water tank 320 may be detachably connected to the module cover 310. Specifically, the water tank 320 is installed in a water tub seating portion formed in the upper cover 312.

[0156] In addition, the water tank 320 may be disposed on the upper portion of the heat generator 336. Specifically, the water tank 320 is disposed on the upper portion of the heat generator 336 and is separated from the heat generator 336. That is, the water tank 320 may be disposed on the upper portion of the heat generator 336 via the upper cover 312.

[0157] When the water tank 320 is installed on the module cover 310 , the water tank 320 may form the appearance of the cleaning module 300 .

[0158] In fact, the entire upper side wall of the water tank 320 can form the top surface appearance of the cleaning module 300. Therefore, the user can visually confirm whether the water tank 320 is installed to the module cover 310.

[0159] The module cover 310 may further include a water tank separation button, which is operated to separate the water tank 320 when the water tank 320 is installed in the module cover 310. For example, the water tank separation button may be located in the center of the cleaning module 300. Therefore, there is an advantage that the user can easily identify the water tank separation button and can operate the water tank separation button.

[0160] In a state where the water tank 320 is mounted on the module cover 310 , water in the water tank 320 may be supplied to the rag 350 .

[0161] Specifically, a space capable of storing water is formed inside the water tank 320. The water stored in the water tank 320 can be supplied to the heat generator 336 through at least one pipe (hose). The water flowing into the heat generator 336 can be heated and can also be phase-changed into steam (water vapor) according to the user's selection. The water heated in the heat generator 336 can be supplied to the rag 350 through the diffuser 337.

[0162] The water tank 320 includes a water supply port. The water supply port is a hole through which water flows into the inside of the water tank 320. For example, the water supply port may be formed on a side of the water tank 320.

[0163] The water tank 320 includes a drain port. The drain port is a hole through which water stored in the water tank 320 is drained. Water discharged from the drain port may flow toward the heat generator 336. The drain port may be formed at a lower surface of the water tank 320.

[0164] The water tank 320 includes an air hole. The air hole is a hole through which air can flow into the inside of the water tank 320. When the water stored in the water tank 320 is discharged to the outside, the pressure inside the water tank 320 decreases, and in order to compensate for the decreased pressure, air can flow into the inside of the water tank 320 through the air hole. For example, the air hole can be formed at the upper end of the water tank 320.

[0165] The cleaning module 300 of the present invention may further include a water supply unit 330 having a flow path for supplying water flowing from the water tank 320 to the mop 350 .

[0166] Specifically, the moisture supply part 330 may include: a water tank connection part 331, which allows water from the water tank 320 to flow into the interior of the module cover 310; a water inflow pipe 332, which supplies the water flowing into the water tank connection part 331 to the water pump 333; a guide pipe 334, which supplies the water from the water pump 333 to the T-shaped connecting piece; and a water supply pipe 335, which supplies the water flowing into the connecting piece to the heat generator 336.

[0167] The water tank connection portion 331 can activate a valve (not shown) in the water tank 320 so that water can flow.

[0168] The water tank connection portion 331 may be coupled to the lower side of the upper cover body 312 , and a portion thereof may pass through the upper cover body 312 and protrude upward.

[0169] When the water tank 320 is placed on the upper cover 312 , the water tank connection portion 331 protruding upward can pass through the discharge port of the water tank 320 and be introduced into the interior of the water tank 320 .

[0170] The upper cover 312 may be provided with a seal for preventing water discharged from the water tank 320 from leaking to the periphery of the water tank connection portion 331. As an example, the seal may be formed of a rubber material and may be coupled to the upper cover 312 at the upper side of the upper cover 312.

[0171] The upper cover 312 may be provided with a water pump 333 for controlling the discharge of water from the water tank 320 .

[0172] The water pump 333 may provide a flow force of water. The water pump 333 may include a first connection port connected to the water inflow pipe 332 and a second connection port connected to the guide pipe 334. At this time, based on the water pump 333, the first connection port may be an inlet, and the second connection port may be an outlet.

[0173] The water pump 333 is a pump that operates in such a way that an internal valve body expands or contracts during operation to connect the first connection port with the second connection port. It can be implemented by a well-known structure, so a detailed description is omitted.

[0174] The water supply pipe 335 may connect the connection member and the water flow inlet 336b of the heat generator 336. For example, the water supply pipe 335 may be a pair of pipes branched from the connection member.

[0175] Therefore, the water supplied to the water inflow pipe 332 flows toward the guide pipe 334 after being introduced into the inside of the water pump 333. The water flowing to the guide pipe 334 flows to the water supply pipe 335 through the connector. And, the water flowing to the water supply pipe 335 is supplied to the heat generator 336.

[0176] The heat generator 336 is a device for heating water. The heat generator 336 is arranged inside the module cover 310. Specifically, the heat generator 336 is provided on the upper surface of the lower cover 311.

[0177] The heat generator 336 includes a heating chamber 336a, a water inlet 336b, and a water discharge port 336c.

[0178] A flow path is formed inside the heating chamber 336a for the water flowing in from the water tank 320 to flow. The heating chamber 336a can receive power from the battery 190 and / or the auxiliary battery 500 to heat water. The heating chamber 336a can adjust the temperature of the water according to the control of the user. In addition, the heating chamber 336a can change the phase of water into steam (water vapor) according to the control of the user.

[0179] 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 flow into the heat generator 336 through the water inlet 336b.

[0180] The moisture outlet 336c may be a hole formed at the outlet end of the heating chamber 336a. Water or steam may be discharged from the heat generator 336 through the moisture outlet 336c. The moisture outlet 336c may be connected to the diffuser 337.

[0181] On the other hand, in the present invention, the heat generator 336 is arranged at an inclination. Specifically, the heating chamber 336a is arranged at an inclination at a predetermined angle with respect to the ground (floor surface).

[0182] For example, the rear end of the heating chamber 336a is arranged at a position closer to the upper part than the front end of the heating chamber 336a. That is, the heat generator 336 has an inclination in the rear direction. Thus, water can be heated while flowing from the upper rear part to the lower front part of the heat generator 336.

[0183] On the other hand, the water inlet 336b can be arranged at the rear end of the heating chamber 336a, and the water outlet 336c can be arranged at the front end of the heating chamber 336a. That is, based on the state where the lower cover 311 is placed on the floor surface (ground), the water inlet 336b can be farther away from the floor surface (ground) than the water outlet 336c. Thus, water is heated while flowing from the upper part to the lower part under the action of gravity, and even if the water changes into water vapor and rises, it can be discharged to the water outlet 336c by the flow force of the water.

[0184] The diffuser 337 is configured to discharge the water in the water tank 320 toward the mop 350 .

[0185] The diffuser 337 may be accommodated in a space formed inside the module cover 310. The diffuser 337 is connected to the heat generator 336, and can discharge the water heated in the heat generator 336 to the rag 350.

[0186] As an example, a pair of diffusers 337 may be installed in the module housing 310 and may be arranged in the left-right direction. In addition, the pair of diffusers 337 arranged in the left-right direction may be formed in shapes symmetrical to each other (mirror images).

[0187] In this embodiment, the diffuser 337 has a diffusion channel formed therein for water to flow, and includes a nozzle for discharging the water flowing through the diffusion channel toward the rag.

[0188] As an example, the diffuser 337 is formed in an arc shape, and at least one nozzle may be arranged along the circumferential direction. With such a configuration, the diffuser 337 can stably supply water to the dishcloth 350 in a disc shape.

[0189] The water sprayed from the diffuser 337 is supplied to the rag 350. As an example, the distance from the diffuser 337 to the rotary cleaning unit 340 based on the rotation center may be greater than the diameter of the rotary cleaning unit 340. Therefore, the water sprayed from the diffuser 337 may be directly supplied to the rag 350. The rag 350 rotates in a state of absorbing the water supplied by the diffuser 337 and wipes the floor.

[0190] The rotary cleaning unit 340 may receive power from the rag driving motor 370 to rotate. For example, the rotary cleaning unit 340 may be a rotating disk. The rotary cleaning unit 340 may be formed in a disk shape, and a rag 350 may be attached to the bottom surface.

[0191] As an example, the rotary cleaning unit 340 may be located behind the suction port 313 a on the lower side of the module cover 310 .

[0192] Therefore, when the cleaning module 300 is moved forward for cleaning, foreign matter and air on the floor surface can be sucked in through the suction port 313 a , and then the floor surface can be wiped with the mop 350 .

[0193] As an example, the rotary cleaning unit 340 may include: a first rotary cleaning unit 341 connected to the first rag driving motor 371 and having the first rag 351 attached thereto; and a second rotary cleaning unit 342 connected to the second rag driving motor 372 and having the second rag 352 attached thereto.

[0194] Specifically, the rotary cleaning unit 340 may include: an outer body in a circular ring shape; an inner body located in the central area of ​​the outer body and separated from the inner circumference of the outer body; and a plurality of connecting ribs connecting the outer circumference of the inner body and the inner circumference of the outer body.

[0195] On the other hand, the rotary cleaning unit 340 may include an attachment means for attaching the rag 350. As an example, the attachment means may be Velcro.

[0196] The rotary cleaning unit 340 may be disposed at the lower side of the lower cover 311 . That is, the rotary cleaning unit 340 may be disposed outside the module cover 310 .

[0197] In addition, the rotary cleaning unit 340 may be connected to the rag driving motor 370 to receive power. For example, the rotary cleaning unit 340 may be connected to the rag driving motor 370 using at least one gear, and may be rotated by the operation of the rag driving motor 370.

[0198] The rotation cleaning unit 340 may include a first rotation cleaning unit 341 and a second rotation cleaning unit 342 .

[0199] 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 arranged to be spaced apart in the left-right direction.

[0200] The rotation center of the rotary cleaning unit 340 may be further away from the front end of the module cover 310 than the central axis that divides the front-to-back length of the module cover 310 equally. This is to prevent the rotary cleaning unit 340 from blocking the suction port 313a.

[0201] The distance between the rotation center of the first rotary cleaning part 341 and the rotation center of the second rotary cleaning part 342 may be formed to be larger than the diameter of the rag 350. This is to reduce the mutual friction caused by the interference between the first rag 351 and the second rag 352 during the rotation process, and prevent the cleanable area from being reduced by an amount corresponding to the interference portion.

[0202] The rag 350 may wipe the floor surface by a rotating motion.

[0203] The mop 350 may be coupled to the lower side of the rotary cleaning unit 340 in a manner facing the floor surface.

[0204] The rag 350 is formed to have a predetermined area on the bottom surface facing the floor, and is formed in a flat shape. The rag 350 is formed in a shape in which the horizontal width (or diameter) is sufficiently larger than the vertical height. When the rag 350 is coupled to the lower cover 311 side, the bottom surface of the rag 350 can be parallel to the floor surface.

[0205] The bottom surface of the rag 350 may be formed in a substantially circular shape, and the rag 350 may be formed in a rotationally symmetrical shape as a whole. In addition, the rag 350 may be attached to and detached from the bottom surface of the rotary cleaning unit 340, and may be combined with the rotary cleaning unit 340 to rotate together with the rotary cleaning unit 340.

[0206] When the rotating cleaning unit 340 is combined with the lower side of the module cover 310, a portion of the rag 350 protrudes toward the outside of the cleaning module 300, thereby not only cleaning the floor surface below the cleaning module 300, but also cleaning the floor surface outside the cleaning module 300.

[0207] As an example, the rag 350 may not only protrude toward the sides of the cleaning module 300, but also protrude toward the rear.

[0208] The rag 350 may include a first rag 351 coupled to the first rotary cleaning unit 341 and a second rag 352 coupled to the second rotary cleaning unit 342. Therefore, when the first rotary cleaning unit 341 receives the power of the first rag driving motor 371 to rotate, the first rag 351 may also rotate together, and when the second rotary cleaning unit 342 receives the power of the second rag driving motor 372 to rotate, the second rag 352 may also rotate together.

[0209] On the other hand, in this embodiment, the cleaning module 300 may further include a light emitting module 360 ​​.

[0210] The light emitting module 360 ​​may irradiate light in front of the cleaning module 300 to check foreign matter or microorganisms existing in front of the cleaning module 300 .

[0211] The light emitting module 360 ​​may be arranged in front of the module cover 310. For example, the light emitting module 360 ​​may be arranged in front of the lower cover 311, and a plurality of light emitting modules 360 may be arranged in the left-right direction. In this case, the light emitting module 360 ​​may be arranged behind the cooling air inlet 317. With such an arrangement, the light emitting module 360 ​​may be cooled by the air flowing in from the cooling air inlet 317.

[0212] On the other hand, the light emitting module 360 ​​may be composed of a light emitting member and a diffusion plate.

[0213] The light emitting component can irradiate light to the front or the bottom. As an example, the light emitting component can be composed of a plurality of LEDs. In this case, the light irradiated by the light emitting component can be visible light, and according to the embodiment, it can be infrared (IR) or ultraviolet (UV). With such a structure, when the light emitting component is in operation, it is possible not only to confirm the foreign matter or microorganisms present in front of the cleaning module 300, but also to improve the sanitation effect by sterilizing the foreign matter or microorganisms present in front of the cleaning module 300.

[0214] In addition, the diffusion plate is disposed in front of the light emitting member and can diffuse the light emitted from the light emitting member.

[0215] On the other hand, the cleaning module 300 may further include a rag driving motor 370 that provides power to rotate the rag 350 and the rotary cleaning unit 340 .

[0216] Specifically, the rag driving motor 370 may include a first rag driving motor 371 which rotates the first rotary cleaning unit 341 and a second rag driving motor 372 which rotates the second rotary cleaning unit 342 .

[0217] As described above, since the first rag driving motor 371 and the second rag driving motor 372 operate independently, there is an advantage that even if one of the first rag driving motor 371 and the second rag driving motor 372 fails, the other rag driving motor can be used to rotate the rotary cleaning unit 340.

[0218] On the other hand, the first rag driving motor 371 and the second rag driving motor 372 may be arranged in a spaced relationship along the left-right direction of the module cover 310. Also, the first rag driving motor 371 and the second rag driving motor 372 may be located behind the suction port 313a.

[0219] The mop drive motor 370 may be disposed in the module cover 310. As an example, the mop drive motor 370 is disposed on the upper side of the lower cover 311 and may be covered by the upper cover 312. That is, the mop drive motor 370 may be located between the lower cover 311 and the upper cover 312.

[0220] on the other hand, Fig. 9 A diagram is shown for explaining the combination direction of the auxiliary battery cover and the cleaning module in a vacuum cleaner according to an embodiment of the present invention. Fig.12 A partial stereoscopic view of a connecting pipe in a vacuum cleaner for explaining an embodiment of the present invention is shown.

[0221] Below, refer to Figures 1 to 9 , Fig.12 The connecting pipe 380 will be described.

[0222] The cleaning module 300 includes a connection pipe 380 coupled to the cleaner body 100 or the extension pipe 200 .

[0223] The connection pipe 380 may include a first connection pipe 381 connected to an end of the flow path forming portion 313 , a second connection pipe 382 rotatably connected to the first connection pipe 381 , and a guide pipe connecting the insides of the first connection pipe 381 and the second connection pipe 382 .

[0224] The first connecting pipe 381 is formed in a tube shape, and one end portion on the axial side can be connected to the end of the flow path forming portion 313, and the other end portion on the axial side can be rotatably combined with the second connecting pipe 382. At this time, the first connecting pipe 381 is formed in a shape in which a part of the outer peripheral surface is cut away, and the cut away part can be configured to face the second connecting pipe 382 and the upper side. Through such a structure, when the cleaning module 300 is placed on the ground, the angle formed by the second connecting pipe 382 and the ground can be changed as the user's arm moves. That is, the first connecting pipe 381 and the second connecting pipe 382 can perform a joint action that can adjust the angle between the cleaning module 300 and the vacuum cleaner body 100.

[0225] On the other hand, in the present embodiment, the second connection pipe 382 may be combined with the auxiliary battery cover 400 .

[0226] The second connection pipe 382 includes a connection pipe body 382 a , a battery support portion 382 b , a battery connection portion 382 c , and a hook receiving groove 382 d .

[0227] The connecting pipe body 382a is formed in a pipe shape, and one axial end portion is rotatably coupled to the first connecting pipe 381, and the other axial end portion is inserted into the cleaner body 100 or the extension pipe 200 and detachably coupled thereto.

[0228] The battery support part 382b and the battery connection part 382c may be formed to protrude from the outer front of the connection pipe body 382a. When the auxiliary battery cover 400 is coupled, the battery support part 382b and the battery connection part 382c may contact the auxiliary battery cover 400 and support each other.

[0229] The battery connection part 382c may be formed protrudingly at the front of the outer side of the connection tube body 382a, and may be combined with the combination part 420 of the auxiliary battery cover 400. At this time, a corresponding terminal 382ca may be formed on the upper side of the battery connection part 382c, a combination groove 382cb may be formed in front of the battery connection part 382c, a side wall 382cd may be formed protrudingly at the outer profile of the combination groove 382cb, and a communication terminal 382cc may be arranged inside the combination groove 382cb.

[0230] The corresponding terminal 382ca is formed to receive the coupling terminal 450 of the auxiliary battery cover 400. For example, the corresponding terminal 382ca may be formed in a pair of circular groove shapes on the upper side of the battery connecting portion 382c.

[0231] With such a configuration, the auxiliary battery cover 400 can be moved downward along the length direction of the second connecting tube 382 so that the connecting terminal 450 is inserted and connected to the corresponding terminal 382ca (see Fig. 9 ).

[0232] The coupling groove 382cb is formed to accommodate the second coupling portion 422. For example, the coupling groove 283cb is disposed in front of the battery connecting portion 382c and may be formed in a shape that is open on the upper side and surrounded by a "U"-shaped side wall 382cd on the lower side.

[0233] With such a configuration, the connection direction of the auxiliary battery cover 400 can be guided so as to move downward along the length direction of the second connection pipe 382 .

[0234] In addition, the left-right width of the coupling groove 283cb may be greater than or equal to the left-right maximum width of the second coupling portion 422. Therefore, when the auxiliary battery cover 400 is coupled, the second coupling portion 422 is accommodated inside the coupling groove 283cb and can be stably supported.

[0235] On the other hand, in a case where the auxiliary battery cover 400 is coupled to the battery connection portion 382c, the communication terminal 423 of the auxiliary battery cover 400 and the communication terminal 382cc of the battery connection portion 382c may contact each other.

[0236] With such a configuration, the auxiliary battery cover 400 can be connected to the cleaning module 300 by signal.

[0237] At least a portion of the battery support portion 382b is disposed inside the battery connection portion 382c and can be combined with the first combination portion 421. The battery support portion 382b can be formed in a shape that is more convex to the upper side than the battery connection portion 382c. In this case, the left-right width of the battery support portion 382b can be greater than the interval between the pair of first combination portions 421.

[0238] With such a configuration, when the auxiliary battery cover 400 is coupled, the battery support portion 382 b can be sandwiched between the pair of first coupling portions 421 , thereby having an effect of supporting the auxiliary battery cover 400 from shaking in the left-right direction.

[0239] The hook receiving groove 382 d is formed at the battery connecting portion 382 c and can receive the stopper 430 in a state where the auxiliary battery cover 400 is coupled to the cleaning module 300 .

[0240] Specifically, the hook receiving groove 382d may be formed on the outer circumferential surface of the side wall 382cd of the battery connecting portion 382c. When the auxiliary battery cover 400 is coupled, the hook portion 431 of the stopper 430 may be received in the hook receiving groove 382d.

[0241] Therefore, if Fig.14 As shown, in the state where the auxiliary battery cover 400 is coupled, the inner circumferential surface of the side wall 382 cd contacts the second coupling portion 422 , and the outer circumferential surface of the side wall 382 cd contacts the hook portion 431 .

[0242] With such a configuration, the hook 431 is received in the hook receiving groove 382 d , thereby preventing the auxiliary battery cover 400 from being separated from the cleaning module 300 during the cleaning process.

[0243] On the other hand, electric wires may be built into the first connecting pipe 381 and the second connecting pipe 382, ​​and the electric wires built into the first connecting pipe 381 and the second connecting pipe 382 may be electrically connected to each other. With such a configuration, the current applied from the battery 190 of the cleaner body 100 or the auxiliary battery 500 may be transmitted to the cleaning module 300.

[0244] On the other hand, the guide pipe may connect the inner space of the first connecting pipe 381 and the inner space of the second connecting pipe 382. A flow path may be formed inside the guide pipe so that the air sucked from the cleaning module 300 flows toward the extension pipe 200 and / or the cleaner body 100. At this time, the guide pipe may be deformed together with the rotation of the first connecting pipe 381 and the second connecting pipe 382. As an example, the guide pipe may be formed into a corrugated pipe shape.

[0245] On the other hand, the cleaning module 300 may include a printed circuit board 390 configured with a module control unit (not shown) for controlling the cleaning module 300. The printed circuit board 390 may be supplied with a current and may be provided with a communication line. At this time, the printed circuit board 390 may be cooled by air flowing in through the cooling air inlet 317 and discharged through the cooling air outlet 318.

[0246] On the other hand, the module cover 310 may further include a first operating portion 391 for adjusting the amount of water discharged from the water tank 320. As an example, the first operating portion 391 may be located at the rear side of the module cover 310.

[0247] The user may operate the first operating part 391 , and through the operation of the first operating part 391 , water may be discharged from the water tank 320 or may be prevented from being discharged.

[0248] Alternatively, the amount of water discharged from the water tank 320 can be adjusted by the first operating part 391. For example, as the user operates the first operating part 391, a first amount of water can be discharged from the water tank 320 per unit time, or a second amount of water greater than the first amount can be discharged per unit time.

[0249] The first operating portion 391 may be configured to pivot in the left-right direction on the module cover 310 , or may be configured to pivot in the up-down direction according to an embodiment.

[0250] For example, when the first operating part 391 is in the neutral position, the water discharge amount is 0, and if the left side of the first operating part 391 is pressed to pivot the first operating part 391 to the left, a first amount of water can be discharged from the water tank 320 within a unit time. Furthermore, if the right side of the first operating part 391 is pressed to pivot the first operating part 391 to the right, a second amount of water can be discharged from the water tank 320 within a unit time.

[0251] On the other hand, the module cover 310 may further include a second operating portion 392 for adjusting the phase of the water discharged from the heat generator 336. As an example, the second operating portion 392 may be located at the rear side of the module cover 310.

[0252] The user may operate the second operating part 392 , and by operating the second operating part 392 , water or steam (water vapor) may be ejected from the heat generator 336 toward the rag 350 .

[0253] The second operating portion 392 may be rotatably disposed on the module cover 310. For example, the second operating portion 392 may be a rotary handle (turntable).

[0254] For example, when the second operating part 392 is rotated and pointed to the first position, water at room temperature may be discharged to the rag 350 without heating the water in the heat generator 336. In addition, when the second operating part 392 is rotated and pointed to the second position different from the first position, water may be heated in the heat generator 336 and discharged to the rag 350. In addition, when the second operating part 392 is rotated and pointed to the third position different from the first position and the second position, water may be heated in the heat generator 336 and discharged to the rag 350 after the water is phase-changed into steam (water vapor).

[0255] on the other hand, Fig.10 A three-dimensional diagram of an auxiliary battery cover in a vacuum cleaner for explaining an embodiment of the present invention is shown. Fig.11 Shown from another direction Fig.10 A stereogram of Fig.12 A partial stereoscopic view of a connecting pipe in a vacuum cleaner for illustrating an embodiment of the present invention is shown. Fig.13 A three-dimensional view of a stopper and a separation button of an auxiliary battery cover in a vacuum cleaner for explaining an embodiment of the present invention is shown. Fig.14 A diagram is shown for explaining a state in which an auxiliary battery cover and a cleaning module are combined in a vacuum cleaner according to an embodiment of the present invention. Fig.15 A diagram for explaining a state in which an external force is applied to a separation button and the fixing of the auxiliary battery cover and the cleaning module is released in a vacuum cleaner according to an embodiment of the present invention is shown.

[0256] Below, refer to Figures 1 to 15 , illustrating an auxiliary battery cover 400 according to an embodiment of the present invention.

[0257] The auxiliary battery cover 400 can be detachably coupled to the cleaning module 300, and the auxiliary battery 500 can be detachably coupled to the auxiliary battery cover 400. Specifically, the auxiliary battery cover 400 is coupled to the connection pipe 380 of the cleaning module 300, and can detachably accommodate the auxiliary battery 500 therein. When the auxiliary battery cover 400 is coupled to the cleaning module 300, the auxiliary battery cover 400 can be disposed between the extension pipe 200 and the cleaning module 300.

[0258] Therefore, according to the present invention, the load of the auxiliary battery 500 is transmitted to the cleaning module 300 through the connection pipe 380 and can be distributed to the entire cleaning module 300 along the connection pipe 380 and the module cover 310. Therefore, there is an effect that the user can easily operate the cleaning module.

[0259] On the other hand, to facilitate understanding, the following defines the direction of the auxiliary battery cover 400. In this embodiment, the direction can be described based on the state where the auxiliary battery cover 400 is coupled to the connection pipe 380 and the extension pipe 200 is arranged in a direction perpendicular to the ground.

[0260] Therefore, in the auxiliary battery cover 400, the lower side may refer to the direction toward the first connection pipe 381. In addition, the upper side of the auxiliary battery cover 400 may refer to the direction toward the cleaner body 100. In addition, the front of the auxiliary battery cover 400 may refer to the direction away from the second connection pipe 382. And, the rear of the auxiliary battery cover 400 may refer to the direction facing the second connection pipe 382.

[0261] On the other hand, in the present embodiment, the auxiliary battery receiving portion 410 may be disposed farther from the floor surface than the coupling portion 420 .

[0262] That is, when the auxiliary battery 500 is combined with the auxiliary battery cover 400 and the auxiliary battery cover 400 is combined with the cleaning module 300, when the vacuum cleaner body 100 is placed on the floor, at least a portion of the extension tube 200 can be configured to be closer to the floor than the auxiliary battery 500.

[0263] In addition, when the auxiliary battery 500 is coupled to the auxiliary battery cover 400 and the auxiliary battery cover 400 is coupled to the cleaning module 300, when the cleaning module 300 is placed on the floor, at least a portion of the auxiliary battery 500 may be disposed further away from the floor than the connection pipe 380. For example, the upper end of the auxiliary battery 500 may be disposed further away from the floor than the upper end of the connection pipe 380.

[0264] Also, 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 and the cleaning module 300 are combined.

[0265] With such a structure, when the user stands the extension tube 200 approximately vertically relative to the cleaning module 300, the extension tube 200 and the cleaner body 100 can achieve a self-standing effect of standing vertically relative to the ground.

[0266] On the other hand, the auxiliary battery cover 400 may be arranged at a predetermined distance from the module cover 310 of the cleaning module 300. For example, when the second connection pipe 382 is arranged in a direction perpendicular to the ground, the lowest part of the auxiliary battery cover 400 may be arranged above the highest part of the upper cover 312.

[0267] Therefore, according to the present invention, there is an effect of preventing the auxiliary battery cover 400 from interfering with the cleaning module 300 during the cleaning process.

[0268] The auxiliary battery cover 400 includes an auxiliary battery receiving portion 410 , a coupling portion 420 , a stopper 430 , a separation button 440 , a terminal 450 , a battery display portion 460 , and an input button 470 .

[0269] The auxiliary battery cover 400 may include an auxiliary battery receiving portion 410 formed with an auxiliary battery receiving groove 412 into which the auxiliary battery 500 is inserted.

[0270] The auxiliary battery 500 may be detachably coupled to the auxiliary battery receiving portion 410. The auxiliary battery 500 may be detachably received inside the auxiliary battery receiving portion 410.

[0271] Specifically, the auxiliary battery receiving portion 410 may include a receiving portion body 411 and an auxiliary battery receiving groove 412 .

[0272] The receiving portion body 411 constitutes the appearance of the auxiliary battery cover 400 , and the auxiliary battery 500 can be received inside the receiving portion body 411 .

[0273] As an example, the housing body 411 may be composed of a pair of faces facing each other and a curved surface connecting the pair of faces. That is, when the auxiliary battery cover 400 is coupled to the cleaning module 300, the front side 411a of the housing body 411 may be arranged in a direction away from the connection pipe 380, and the back side 411b of the housing body 411 may be arranged in a position facing the connection pipe 380, the front side 411a and the back side 411b are arranged parallel to each other, and the left and right directions and lower ends of the front side 411a and the back side 411b are connected to each other.

[0274] Therefore, one axial end of the receiving portion body 411 may be formed into an open shape to accommodate the auxiliary battery 500, and the other axial end of the receiving portion body 411 may be formed into a shape with a width gradually narrowing in the left-right direction. With such a configuration, the receiving portion body 411 accommodates the auxiliary battery 500 inside and can minimize the overall volume and weight.

[0275] The auxiliary battery 500 can be accommodated in the auxiliary battery receiving groove 412. The auxiliary battery receiving groove 412 can be formed in a shape corresponding to the shape of the auxiliary battery main body 510 so that the auxiliary battery main body 510 can be inserted. For example, the diameter of the auxiliary battery receiving groove 412 in the front-to-back direction can be greater than or equal to the diameter of the battery main body 510 in the front-to-back direction. In addition, the diameter of the auxiliary battery receiving groove 412 in the left-to-right direction can be greater than or equal to the diameter of the battery main body 510 in the left-to-right direction. In addition, the curvature of the side wall of the auxiliary battery receiving groove 412 can be the same as the curvature of the outer side surface of the battery main body 510 facing it.

[0276] On the other hand, the auxiliary battery receiving groove 412 may be formed to have a side wall having an inclined surface at a predetermined angle when the auxiliary battery cover 400 is coupled to the connecting pipe 380. At this time, the entrance of the auxiliary battery receiving groove 412 for inserting the auxiliary battery 500 may be opened upward at a predetermined angle with respect to the ground.

[0277] Therefore, the auxiliary battery 500 can be inserted and coupled to the auxiliary battery cover 400 at an angle downward. Specifically, the direction in which the auxiliary battery receiving groove 412 is formed can form an angle of more than 0 degrees and less than 90 degrees with the axial direction of the extension tube 200. As an example, an imaginary extension line passing through the interior of the auxiliary battery receiving groove 412 can be parallel to an imaginary extension line passing through the internal flow path of the extension tube 200 or intersect each other at an angle less than 90 degrees. That is, the direction in which the auxiliary battery 500 is inserted can form an angle of more than 0 degrees and less than 90 degrees with the length direction of the extension tube 200.

[0278] The auxiliary battery receiving portion 410 may include a connection terminal. Although not shown, the connection terminal may be disposed inside the receiving portion body 411 .

[0279] The connection terminal (not shown) may be provided at the lower end of the auxiliary battery receiving slot 412. That is, the connection terminal may be arranged at a position in the auxiliary battery receiving slot 412 that is farthest from the entrance for inserting the auxiliary battery 500. With such a configuration, when the auxiliary battery 500 is coupled to the auxiliary battery receiving slot 412, the connection terminal may contact the terminal provided at the electrical connection portion 540 of the auxiliary battery 500.

[0280] The auxiliary battery receiving portion 410 may further include a stopper 414 and a fastening hole (not shown). In this case, the stopper 414 and the fastening hole may be formed on both sides of the receiving portion body 411 .

[0281] The stopper 414 can be hooked with the auxiliary battery 500. The stopper 414 can be formed on a side surface in the left-right direction of the receiving portion body 411. The stopper 414 can be coupled with the first coupling button 520 of the auxiliary battery 500. At this time, the stopper 414 can lock and support the first button part 521, and can be hooked with the first hook 522.

[0282] The fastening hole (not shown) may be hooked with the auxiliary battery 500. The fastening hole may be formed on the other side of the accommodating portion body 411 in the left and right directions. The second coupling button 530 of the auxiliary battery 500 may be coupled to the fastening hole. At this time, the second hook 532 may be hooked with the fastening hole.

[0283] Therefore, when the auxiliary battery 500 is inserted into the auxiliary battery receiving groove 411 , the locking platform 414 and the fastening hole are hooked with the auxiliary battery 500 , thereby preventing the auxiliary battery 500 from being detached.

[0284] The coupling portion 420 is formed to protrude from the auxiliary battery receiving portion 410 and may be coupled to the cleaning module 300 .

[0285] Specifically, the coupling part 420 includes a first coupling part 421 and a second coupling part 422. At this time, the first coupling part 421 and the second coupling part 422 can be formed on the back side 411b of the auxiliary battery receiving part 410. That is, based on the state in which the auxiliary battery cover 400 is coupled to the cleaning module 300, the first coupling part 421 and the second coupling part 422 can be formed to protrude from the receiving part body 411 toward the connecting pipe 380.

[0286] The first coupling portion 421 is formed to protrude from the auxiliary battery receiving portion 410 and may be provided with a coupling terminal 450 electrically connected to the cleaning module 300 .

[0287] In addition, the second coupling portion 422 is protruded from the auxiliary battery receiving portion 420 and may be connected to the first coupling portion 421 .

[0288] At this time, based on the state that the auxiliary battery cover 400 is coupled to the cleaning module 300, the first coupling portion 421 can be disposed at a position farther from the ground than the second coupling portion 422. In other words, the first coupling portion 421 can be disposed at a position farther from the first connecting pipe 381 of the connecting pipe 380 than the second coupling portion 422.

[0289] For example, the first connecting portion 421 may be formed in a pair of shapes protruding in parallel along the length direction. Also, the second connecting portion 421 may be formed protruding in a “U” shape, and a pair of upper end portions may be connected to the first connecting portion 421 , respectively.

[0290] On the other hand, a protrusion height of the first coupling portion 421 from the auxiliary battery receiving portion 410 may be higher than a protrusion height of the second coupling portion 422 from the auxiliary battery receiving portion 410 .

[0291] By such a configuration, the first and second coupling parts 421 and 422 can be supported by the battery connection part 382c of the second connection pipe 382. Specifically, when the user lifts the cleaner body 100, the lower side of the first coupling part 421 can be supported by the upper side of the battery connection part 382c.

[0292] In addition, the second coupling portion 422 can be accommodated in the groove formed in the battery connecting portion 382c. That is, the second coupling portion 422 formed in a "U" shape can move along the coupling groove 382cb formed in the battery connecting portion 382c and can be accommodated in the inside of the coupling groove 382cb.

[0293] This configuration can guide the direction of the coupling portion 420 and the second connection pipe 382. In addition, when the coupling portion 420 and the second connection pipe 382 are coupled, the second coupling portion 422 can be supported by contacting the side wall protruding from the outer contour of the coupling groove 382cb.

[0294] Therefore, when the user lifts up the cleaner body 100 for use, the auxiliary battery cover 400 can be hung on the battery connecting portion 382c and supported.

[0295] Therefore, according to the present invention, the auxiliary battery cover 400 may be coupled or separated along the length direction of the second connection pipe 382 of the cleaning module 300 (or the length direction of the extension pipe 200 ).

[0296] On the other hand, the coupling portion 420 may further include a communication terminal 423. The communication terminal 423 may be disposed at the second coupling portion 422. The communication terminal 423 may be electrically connected to the cleaning module 300 and / or the vacuum cleaner body 100. Using the communication terminal 423, the printed circuit board disposed on the auxiliary battery cover 400 and the printed circuit board disposed on the cleaning module 300 and / or the vacuum cleaner body 100 may transmit and receive electric signals.

[0297] With such a configuration, the auxiliary battery cover 400 can communicate with the cleaning module 300 and / or the cleaner body 100 .

[0298] The stopper 430 may be provided in the auxiliary battery receiving portion 410 so as to be linearly reciprocating. The stopper 430 includes a hook portion 431, a moving portion 432, and a through portion 433. The stopper 430 may be formed and arranged in the auxiliary battery receiving portion 410 along the length direction, and at least a portion thereof may be exposed to the outside of the auxiliary battery receiving portion 410. For example, the stopper 430 is formed in a rod shape. At this time, the hook portion 431 is arranged on one side of the length direction of the stopper 430, the moving portion 432 is arranged on the other side of the length direction, and the through portion 433 is arranged between the hook portion 431 and the moving portion 432. Furthermore, the moving portion 432 may be in contact with the return spring 434.

[0299] When the auxiliary battery cover 400 and the cleaning module 300 are combined, the hook 431 can contact the cleaning module 300. The hook 431 can be arranged on the auxiliary battery cover 400 so as to be able to reciprocate linearly. With the linear reciprocating motion, at least a portion of the hook 431 can enter the interior of the auxiliary battery cover 400, or can be exposed to the outside of the auxiliary battery cover 400. At this time, the hook 431 can be exposed on one side (i.e., the back side 511b) of the auxiliary battery accommodating portion 410 where the second coupling portion 421 is protruded. Therefore, the hook 431 can contact and be supported by the connecting pipe 380 of the cleaning module 300.

[0300] For example, when the auxiliary battery cover 400 and the cleaning module 300 are combined, the lower part of the hook 431 (in the direction of the first connecting pipe 391) can be formed into a curved surface shape, and the thickness in the vertical direction can become narrower as it moves away from the auxiliary battery cover 400. At this time, the outer end of the hook 431 (the end in the direction away from the auxiliary battery cover 400) can be formed into a shape in which the lower side gradually approaches the upper side.

[0301] With such a configuration, during the process of combining the auxiliary battery cover 400 with the connecting pipe 380, even if the lower side of the hook 431 contacts the battery connecting portion 382c, the battery connecting portion 382c can move along the curved surface formed on the lower side of the hook 431, thereby preventing the hook 431 from being damaged.

[0302] In addition, during the process of combining the auxiliary battery cover 400 with the connection pipe 380 , when the hook portion 431 is pressed by the battery connection portion 382 c , it may move toward the inside of the auxiliary battery receiving portion 410 .

[0303] In addition, when the auxiliary battery cover 400 is combined with the connecting pipe 380, the hook portion 431 is received in the hook receiving groove 382d formed in the second connecting pipe 382, ​​and the upper side of the hook portion 431 can support the protruding protrusion of the battery connecting portion 382c. Therefore, the stopper 430 can prevent the auxiliary battery receiving portion 410 from being separated from the second connecting pipe 382.

[0304] The moving portion 432 may be connected to the hook portion 431 using the through portion 433 , and may contact the return spring 434 and the separation button 440 .

[0305] The moving portion 432 is disposed inside the auxiliary battery storage portion 410 and is provided to be able to linearly reciprocate along the length direction of the stopper 430 .

[0306] The movable portion 432 is arranged on the other side of the length direction of the stop member 430 , and one side of the length direction of the movable portion 432 (towards the hook portion 431 ) contacts the separation button 440 , and the other side surface of the length direction of the movable portion 432 can contact the return spring 434 .

[0307] When the separation button 440 moves upward, one side of the moving part 432 can contact the inclined surface 443 of the separation button 440 and can move linearly along the inclined surface 443. Specifically, through the upward movement of the inclined surface 443, the moving part 432 can move linearly in the direction where the return spring 434 is arranged, and the return spring 434 can be compressed.

[0308] On the other hand, when the return spring 434 is compressed, the moving portion 432 can move linearly toward the direction where the hook portion 431 is arranged by the restoring force of the return spring 434 .

[0309] The through portion 433 connects the hook portion 431 and the moving portion 432, and the separation button 440 may penetrate the through portion 433. For example, the through portion 433 may include a pair of frames connecting the hook portion 431 and the moving portion 432 and a hole formed between the pair of frames.

[0310] With such a configuration, the frame of the through portion 433 can transmit the force transmitted through the hook portion 431 to the moving portion 432 , and can transmit the restoring force applied to the moving portion 432 to the hook portion 431 .

[0311] In addition, the locking portion 444 of the separation button 440 may pass through the hole of the through portion 433 , and as the separation button 440 moves, at least a portion of the inclined surface 443 may pass through the hole of the through portion 433 .

[0312] With such a configuration, the separation button 440 and the stopper 430 can be arranged crosswise in the auxiliary battery receiving portion 410. Therefore, the overall volume of the auxiliary battery 500 can be minimized.

[0313] The return spring 434 is disposed inside the auxiliary battery receiving portion 410 and can apply elastic force to the stopper 430. For example, the return spring 434 can be a coil spring. One end of the return spring 434 in the length direction can be fixed to the auxiliary battery receiving portion 410, and the other end can be combined with the moving portion 432 of the stopper 430.

[0314] With such a configuration, when the return spring 434 is compressed by the stopper 430 , a restoring force can be generated to move at least a portion of the stopper 430 toward the outside of the auxiliary battery accommodation portion 410 .

[0315] Therefore, when the auxiliary battery cover 400 is combined with the cleaning module 300, the stopper 430 is accommodated in the hook receiving groove 382d by the restoring force of the return spring 434, so that the combination of the stopper 430 and the second connecting pipe 382 can be fixed (refer to Fig.14 ).

[0316] The separation button 440 may be provided in the auxiliary battery receiving portion 410 so as to be linearly reciprocating, and may contact the stopper 430. The separation button 440 may be disposed at the lower side of the auxiliary battery receiving portion 410. Specifically, the separation button 440 is received inside the auxiliary battery receiving portion 410, and the lower end of the separation button 440 may form the appearance of the auxiliary battery cover 400 together with the auxiliary battery receiving portion 410.

[0317] The separation button 440 includes a button portion 441 , a protruding portion 442 , an inclined surface 443 and a locking portion 444 .

[0318] The button portion 441 is provided to allow external force to be applied. The button portion 441 may form the lower appearance of the auxiliary battery cover 400. That is, the outer side of the button portion 441 is exposed to the lower side of the auxiliary battery cover 400, and may indicate a pressing position to the user.

[0319] With such a configuration, it is possible to configure so that the user's index finger and / or middle finger can press the button portion 441 in a state where the user's palm covers the auxiliary battery storage portion 410 .

[0320] The button portion 441 may be configured to be able to move linearly when an external force is applied. For example, a user may press the button portion 441 to move the separation button 440 .

[0321] The protrusion 442 is formed to protrude from the button portion 441 and to extend in a direction intersecting the length direction of the stopper 430. For example, the protrusion 442 may be formed to protrude from the inner side surface of the button portion 441 toward the upper side (the direction in which the auxiliary battery 500 is arranged). The extension direction of the protrusion 442 may be parallel to the direction in which the button portion 441 moves linearly.

[0322] The inclined surface 443 is formed on the protruding portion 442 and forms a predetermined angle with the extending direction of the protruding portion 442. The inclined surface 443 may contact the moving portion 432 of the stopper 430.

[0323] With such a configuration, when an external force is applied to the button portion 441 and the button portion 441 and the protrusion 442 move, the inclined surface 443 can also move (move upward) and simultaneously move the moving portion 432 of the stopper 430 .

[0324] Therefore, when the user applies external force to the button portion 441, the moving portion 432 moves along the inclined surface 443 toward the return spring 434, and the return spring 434 is compressed (refer to Fig.15 ).

[0325] Therefore, when the auxiliary battery cover 400 is coupled to the cleaning module 300, when an external force is applied to the button portion 441, the stopper 430 received in the hook receiving groove 382d is disengaged from the hook receiving groove 382d. Thus, the fixing of the auxiliary battery cover 400 and the cleaning module 300 can be released.

[0326] The stopper 444 is formed to protrude and extend from the protruding portion 442, and is in contact with and supported by the moving portion 432. The stopper 444 is formed to extend upward from the protruding portion 442. At this time, the stopper 444 can be connected to the inclined surface 443. Therefore, the stopper 444 can be accommodated in the hole of the through portion 433, and when the inclined surface 443 contacts the moving portion 432 and moves upward as the separation button 440 moves, the stopper 444 can pass through the hole of the through portion 433.

[0327] With such a configuration, the locking portion 444 and the moving portion 432 can contact and support each other when no external force is applied to the separation button 440. Therefore, the locking portion 444 can prevent the stopper 430 from being separated from the outside of the auxiliary battery receiving portion 410.

[0328] The return spring 445 is disposed inside the auxiliary battery receiving portion 410 and can apply elastic force to the separation button 440. For example, the return spring 445 can be a coil spring. One end of the return spring 445 in the length direction can be fixed to the auxiliary battery receiving portion 410, and the other end can be combined with the button portion 441 of the separation button 440. With such a configuration, when an external force is applied to press the button portion 441, the return spring 445 can generate a restoring force, and when the application of the external force is released, the return spring 445 can return the button portion 441 to its original position.

[0329] Therefore, according to the present invention, the user may press the separation button 440 in a direction parallel to the length direction of the second connection pipe 382 to release the auxiliary battery cover 400 from the cleaning module 300 .

[0330] That is, the user can press the separation button 440 with the index finger and / or the middle finger and pull the entire auxiliary battery cover 400 toward the cleaner body 100 to separate the auxiliary battery cover 400 from the cleaning module 300 .

[0331] Therefore, according to the present invention, when separating the auxiliary battery cover 400 , the direction in which the user presses the separation button 440 and the direction in which the auxiliary battery cover 400 is pulled are made consistent, thereby making it possible for the user to easily separate the auxiliary battery.

[0332] The coupling terminal 450 is arranged at the coupling portion 420 and can be coupled to the battery connecting portion 382c of the second connecting tube 382. For example, the coupling terminal 450 is configured as a pair and can be respectively arranged on the lower side of a pair of first coupling portions 421. The coupling terminal 450 can be inserted and coupled to a corresponding terminal in a groove shape formed in the connecting portion 382c. In this case, the auxiliary battery cover 400 and the cleaning module 300 can be electrically connected through the coupling terminal 450. Therefore, the power of the auxiliary battery 500 can be supplied to the cleaning module 300 through the coupling terminal 450.

[0333] As an example, the connection terminal 450 may connect the auxiliary battery 500 and the battery 190 in series. With such a configuration, the auxiliary battery 500 may be connected in series with the battery 190 to supply power to the cleaning module 300 .

[0334] Therefore, when a high-voltage power source is required, the vacuum cleaner 1 of the present invention can connect the auxiliary battery 500 and the battery 190 in series to supply a high-voltage power source to the cleaning module 300 .

[0335] As another example, the coupling terminal 450 may connect the auxiliary battery 500 and the battery 190 in parallel. With such a configuration, the auxiliary battery 500 may be connected in parallel with the battery 190 to supply power to the cleaning module 300 .

[0336] Therefore, when a large-capacity power source is required, the vacuum cleaner 1 of the present invention can connect the auxiliary battery 500 and the battery 190 in parallel to supply a large-capacity power source to the cleaning module 300 .

[0337] The battery display unit 460 is disposed in the auxiliary battery storage unit 410 and can display the state of the battery 460. For example, the battery display unit 460 can be disposed on the front side 411a of the auxiliary battery storage unit 410 and can display the available power of the auxiliary battery 500. As an example, the battery display unit 460 is composed of a ring-shaped light source and can change the color of light or the light-emitting area according to the available power.

[0338] The input button 470 is disposed in the auxiliary battery receiving portion 410, and the user can input a command. For example, the input button 470 can be disposed on the front side 411a of the auxiliary battery receiving portion 410, and a control command can be input according to the user's input. The input button 470 can send a control signal to the printed circuit board 480 according to the user's touch. Therefore, the input button 470 can start or end the power supply according to the user's operation.

[0339] This configuration makes it easier to input commands than when the user operates the operation units 391 and 392 provided in the cleaning module 300 .
