[0050] FIG. 1 is a perspective view of a vacuum cleaner in accordance with a first embodiment of the present disclosure; FIG. 2 is an enlarged partial view of a part between a water tank and a nozzle assembly of a vacuum cleaner in accordance with a first embodiment of the present disclosure.

[0051] As shown in FIGS. 1 and 2, a vacuum cleaner 1 in accordance with a first embodiment of the present disclosure may include nozzle assembly 20 for sucking dust from a floor and a housing 10 movably connected to nozzle assembly 20.

[0052] The nozzle assembly 20 may allow dust sucked into it to pass into the cleaner body 10.

[0055] The vacuum cleaner 1 may further include a cleaning unit 30 removably coupled to the cleaner body 10.

[0054] The cleaning unit 30 may include a housing 32 having a suction motor (not shown) and a dust collecting unit 31 removably connected to the housing 32 to collect dust separated from the air.

[0055] The dust collecting unit 31 may include an air inlet 31a for receiving air from the vacuum cleaner body 10. The housing 10 of the vacuum cleaner may have an air communication unit 12 in communication with the air inlet 31a. The air communication unit 12 may be located in a portion in which the air inlet 31a is located.

[0056] The dust collecting unit 31 may include a cover (not shown) for opening or closing the air inlet 31a. The cover may open the air inlet 31a by the suction force of the suction motor. On the contrary, when the suction motor is not powered, the cover may close the air inlet 31a.

[0057] Thus, when the suction motor is not actuated, the lid closes the air inlet 31a to prevent dust in the dust collecting unit 31 from escaping the air inlet 31a.

[0058] The housing 32 may have an air outlet 33 to allow air passing through the suction motor to exit the housing 32. In addition, the housing 32 may have a handle 34 in its upper position.

[0059] The cleaning unit 30 may further include a battery (not shown) for supplying power to the suction motor.

[0060] Thus, when the cleaning unit 30 is removed from the cleaner body 10, the user can perform cleaning using the cleaning unit 30.

[0061] Moreover, when the cleaning unit 30 is mounted on the cleaner body 10, the suction motor can be driven.

[0062] The housing 10 of the vacuum cleaner may have a handle 11 of the housing. A control unit 112 may be located adjacent to the housing handle 11. The user can control the suction motor in the treatment unit 30 using the control unit 112.

[0063] The nozzle assembly 20 may include a housing 21 and a connection 22 extending from the nozzle housing 21 and rotatably coupled to the vacuum cleaner housing 10.

[0064] The connection 22 may, for example, extend back behind the nozzle body 21.

[0065] The vacuum cleaner 1 may further include a device for cleaning with water. A water purification device may include a rag 50 and a water tank 40 on which a rag 50 is attached.

[0066] A water tank 40 may be connected to the nozzle assembly 20.

[0067] The water tank 40 may supply water to the rag 50 to wet the rag 50 with water to remove dust from the floor.

[0068] A rag 50 may be secured to the water tank 40 in its lower part using adhesive means (not shown), such as Velcro. Adhesive means for attaching rags 50 to the water tank 40 may not be limited to this.

[0069] In this embodiment, provided that the water tank 40 is fixed to the nozzle assembly 20, the design of the nozzle assembly 20 and / or the presence / absence of the cleaning assembly 30 are not particularly limited.

[0070] Alternatively, the water tank 40 is not connected to the vacuum cleaner, but has a rod connected to the water tank 40 for cleaning the floor using a rag connected to the water tank 40.

[0071] A water tank 40 may be located under the nozzle assembly 20. The water tank 40 may be at least partially located on the outside of the nozzle assembly 20 when connected to the nozzle assembly 20.

[0072] That is, as shown in FIG. 2, the water tank 40 may be partially located under the nozzle body 21 for overlapping with the nozzle body 21. The water tank 40 can be partially located under the connection 22 for overlapping connection with the connection 22. In addition, the water tank 40 can be partially located without overlapping overlap with the body 21 of the nozzle, and with the connection 22.

[0073] Thus, using this embodiment, when the water tank 40 is connected to the nozzle assembly 20, the water tank 40 is partially located on the outside of the nozzle assembly 20 to provide an increase in contact area between the rag 50 and the water tank 40. This can lead to an increase in the contact area between the rag 50 and the floor.

[0074] Using this embodiment, in a one-time cleaning process, a rag 50 can remove dust from a large floor area.

[0075] Furthermore, when the user places one foot on a portion of the water tank 40 on the outside of the nozzle assembly 20, the user can raise the vacuum cleaner 1 to remove the water tank 40 from the nozzle assembly 20. Thus, the user can easily remove the water tank 40 from the vacuum cleaner 1. To remove the water tank 40, the water tank 40 does not need a separate structure.

[0076] In addition, when the water tank 40 is in contact with the nozzle assembly 20, the contact area between the vacuum cleaner and the floor increases and provides a more reliable vertical arrangement of the vacuum cleaner on the floor in the standby mode of the vacuum cleaner.

[0077] The water tank 40 may be connected to the nozzle body 21 and / or the connection 22.

[0078] The joint 22 may have one or more rear wheels 23 to allow easy movement of the nozzle assembly 20.

[0079] FIG. 3 is a perspective view of a water tank in accordance with a first embodiment of the present disclosure; FIG. 4 is a bottom view of a nozzle assembly in accordance with a first embodiment of the present disclosure.

[0080] As shown in FIGS. 3 and 4, the nozzle body 21 may have an air inlet 212.

[0081] Furthermore, the nozzle body 21 may have one or more front wheels 214 for moving the nozzle assembly 20.

[0082] That is, the nozzle assembly 20 may have a plurality of wheels 23 and 214. The plurality of wheels 23 and 214 may include one or more front wheels 214 located on the nozzle body 21, and one or more rear wheels 23 located on the connection 22.

[0083] To reliably move the nozzle assembly 20, a plurality of front wheels 214 may be located on the nozzle body 21. The plurality of front wheels 214 may be spaced apart from each other in a left-right direction.

[0084] In order to prevent blocking of the air inlet 212 of the water tank 40, the water tank 40 may be located behind the air inlet 212. Furthermore, to prevent interference between the water tank 40 and the plurality of wheels 23 and 214, the water tank 40 can be located at the front of the front wheel 214 and the front of the rear wheel 23.

[0085] That is, when the water tank 40 is connected to the nozzle assembly 20, the water tank 40 can be located between the front wheel 214 and the rear wheel 23. In addition, the water tank 40 can be located between the air inlet 212 and the rear wheel 23.

[0086] The water tank 40 may include a housing plate 410.

[0087] On the bottom of the housing plate 410, the rag 50 may be positioned so that the rag 50 is flat.

[0088] The housing plate 410 may support the connection 22. That is, the connection 22 is located on the housing plate 410.

[0089] The water tank 40 may further include a connecting device connected to the nozzle assembly 20.

[0090] The connecting device may include a first connecting element 421 and 422 connected to the nozzle body 21.

[0091] The first connecting members 421 and 422 may extend upward from the housing plate 410. To firmly connect the water tank 40 to the nozzle body 21, a plurality of first connecting elements 421 and 422 can be mounted on the housing plate 410. The first connecting elements 421 and 422 of the set can be located at a distance from each other in the left-right direction.

[0092] The nozzle body 21 may include a receiving portion 220 for receiving the first connecting member 421 and 422. The receiving portion 220 may be recessed in the nozzle housing 21.

[0093] When a plurality of first connecting elements 421 and 422 are located on the water tank 40, a corresponding number of receiving sections 220 may be located in the nozzle body 21. The receiving sections 220 of the set can be located at a distance from each other in the left-right direction.

[0094] The nozzle body 21 may include hooks 230 connected to the first connecting elements 421 and 422, respectively, when the first connecting elements 421 and 422 are located in the receiving sections 220, respectively.

[0095] Hooks 230 may be secured to nozzle body 21. Each of the hooks 230 may at least partially protrude from each receiving portion 220.

[0096] During the insertion of each first connecting element 421 and 422 into each receiving portion 220, the hook 230 may elastically deform with each first connecting element 421 and 422 of each first connecting element 421 and 422 and then may be aligned with each receiving portion for the hook (not shown ) of each first connecting element 421 and 422, and thus can be placed in each receiving portion for a hook (not shown) of each first connecting element 421 and 422.

[0097] The connecting device may include a second connecting element 430 and 431 connected to the connection 22.

[0098] The second connecting member 430 and 431 may extend upward from the housing plate 410. To firmly secure the water tank 40 to the nozzle body 21, a plurality of second connecting elements 430 and 431 can be mounted on the housing plate 410. The second connecting elements 430 and 431 can be located at a distance from each other in the left-right direction.

[0099] Each of the plurality of second connecting elements 430 and 431 may include an engaging portion to be engaged with the connection 22.

[0100] When a joint 22 is located between a plurality of second connecting elements 430 and 431, an engaging portion of every second connecting elements 430 and 431 may engage with a connecting 22. In one example, an engaging portion of every second connecting elements 430 and 431 may be in contact with a connection 22 on its top surface.

[0101] Since the connection 22 is located between the second connecting elements 430 and 431, the nozzle assembly 20 can be prevented from being removed from the water tank 40 while moving the nozzle assembly 20 in a right or left direction.

[0102] That is, when a force to move the nozzle assembly 20 can be applied to the nozzle assembly 20 in a position in which the connection 22 is not located between the second connecting elements 430 and 431 if the coupling force between the water tank 40 and the nozzle assembly 20 is less friction force between a rag 50 fixed on the water tank 40 and the floor material, the nozzle assembly 20 can be removed from the water tank 40.

[0103] However, using this embodiment, while moving the nozzle assembly 20 in a right or left direction, an effort to move the nozzle assembly 20 can be applied to one of the second connecting members 430 and 431. Thus, the removal of the assembly 20 can be prevented. nozzles from the tank 40 for water, regardless of the frictional force between the rag 50, mounted on the tank 40 for water, and the floor material.

[0104] The water tank 40 may further include a water storage unit 440 for feeding a hearth to the rag 50.

[0105] A block 440 for storing water can be formed from the casing 441 of the camera, made as a whole with the plate 410 of the housing, and a portion of the plate 410 of the housing.

[0106] Furthermore, the camera housing 441 may be integrally formed with one of the plurality of second connecting elements 430 and 431, or may be located at a distance from the plurality of second connecting elements 430 and 431.

[0107] FIG. 5 is a sectional view showing the internal configuration of a water tank in accordance with a first embodiment of the present disclosure; FIG. 6 is a perspective view of a water outlet in accordance with a first embodiment of the present disclosure; FIG. 7 is a perspective view view of a water outlet in accordance with a first embodiment of the present disclosure.

[0108] As shown in FIGS. 5 and 6, the water storage unit 440 may further include a water inlet 442 and a cover 444 for opening or closing the water inlet 442.

[0109] In one example, a water inlet 442 may be formed on the camera case 441.

[0110] The water storage unit 440 may further include a water flow controller 460. That is, the water flow controller 460 can adjust the amount of water flow to the rag 50.

[0111] The water flow controller 460 can block the flow of water to the rag 50. In addition, the water flow controller 460 can change the amount of water flow to the rag 50.

[0112] The water flow controller 460 may be rotatably coupled to a water storage unit 440. In one example, a water flow controller 460 may be coupled to the camera housing 441. The rotation of the water flow controller 460 may change the amount of water flow.

[0113] The water flow controller 460 may include a first element 462 rotatably connected to the water storage unit 440, and a second element 464 connected to the first element 462. The user can lock and rotate the second element 464.

[0114] The first element 462 may be inserted into a block 440 for storing water. The water storage unit 440 may have an engaging rib 450 engaged with the first element 462. The first element 462 may have an outer periphery connected to the inner periphery of the engaging rib 450. In one example, the inner and outer peripheries may be engaged with each other in a helical manner.

[0115] For helical engagement between the engaging rib 450 and the first element 462, the engaging rib 450 may be formed in an annular shape, and the first element 462 may be formed in a cylindrical shape. The inner periphery of the engaging ribs 450 and the outer periphery of the first element 462 are threaded.

[0116] The second element 464 may be coupled to the first element 462 to surround the engaging rib 450. The user can grip and rotate the second element 464 in a clockwise or counterclockwise direction.

[0117] The water flow controller 460 may include a gasket 466. The water storage unit 440 may include a contact portion 412.

[0118] In one example, the gasket 466 may be located on the first element 462. In one example, the contact portion 412 may be located on the plate 410 of the housing.

[0119] When the water flow controller 460 is rotated to block the flow of water, the gasket 466 may contact the contact portion 412.

[0120] The water storage unit 440 may further include an opening 411. A water outlet 470 may be connected to the opening 411. In one example, the opening 411 may be formed in the housing plate 410. The hole 411 may serve as a channel for the flow of water.

[0121] The water outlet 470 may include a flow hole 474. In addition, the contact portion 412 may surround the hole 411 and the hole 474 flow.

[0122] Thus, the gasket 466 is in contact with the contact portion 412 of the contact, the communication between the flow hole 474 and the inner chamber of the water storage unit 440 may be blocked. Thus, water from the water storage unit 440 cannot pass into the flow opening 474.

[0123] In contrast, when the gasket 466 is located at a distance from the contact portion 412, communication between the flow opening 474 and the inner chamber of the water storage unit 440 can be provided. Water from the water storage unit 440 may pass between the gasket 466 and the contact portion 412 and then into the flow opening 474.

[0124] The contact portion 412 may protrude from the housing plate 410 or be recessed in the housing plate 410. As shown in FIG. 5, in one example, the contact portion 412 may protrude from the housing plate 410.

[0125] The contact portion 412 may be formed in an annular shape, and accordingly, the gasket 466 may be formed in an annular shape.

[0126] The water storage unit 440 may further include a guide 413 for guiding the rotation of the water flow controller 460. In one example, guide 413 may extend upward from housing plate 410. In one example, the guide 413 may be formed in a cylindrical shape. Guide 413 may have a greater height than contact portion 412.

[0127] As described above, the first element 462 is engaged with the engaging rib 450 in a helical manner, and thus, rotation of the first element 462 can provide vertical movement of the first element 462.

[0128] In this case, the guide 413 can direct not only the rotation of the first element 462, but also the vertical movement of the first element 462.

[0129] The guide 413 may have a height greater than the height of the contact portion 412. Thus, when the seal 166 is located in an area defined by the guide 413, rotation of the first member 462 may provide contact with the contact portion 412 or spaced apart between the contact portion 412 and contact area 412.

[0130] The guide 413 can prevent the rapid flow of water between the seal 466 and the contact portion 412 when the seal 466 is located at a distance from the contact portion 412.

[0131] When the water storage unit 440 has a level above the height of the guide 413, water from the water storage unit 440 can pass between the inner periphery of the guide 413 and the outer periphery of the first element 462 and then pass between the gasket 466 and the contact portion 412.

[0132] The guide 413 may have a water passage opening 414 formed therein to provide a flow of water between the gasket 466 and the contact portion 412 when the water storage unit 440 is below the height of the guide 413.

[0133] In one example, the water passage opening 414 may have the lowest level substantially flush with the upper surface of the housing plate 410.

[0134] In addition, a plurality of water passage openings 414 may be formed on the guide 413. A plurality of water passage openings 414 may be located on the periphery of the guide 413.

[0135] In one example, the water outlet 470 may be made of rubber material and may be connected to the hole 411 in the housing plate 410. The water outlet 470 may include a connecting portion 472 connected to the opening 411. A flow opening 474 may be formed at the connecting portion 472.

[0136] In order to prevent the rapid flow of water through the flow opening 474, an absorbent element 476 is provided for absorbing water in the flow opening 474. Thus, water remaining in the absorbent member 476 can be supplied to the rag 50.

[0137] When there is no absorption element 476, water can directly pass into the flow hole 474 and then pass to the rag 50. In this case, before the water passes completely to the rag 50, the water passing through the rag 50 can drain to the floor. This may decrease cleaning performance.

[0138] In contrast, as in this embodiment, when the absorbent element 476 is located on the flow hole 484, the absorbent element 476 can provide water retention. This can increase the time for supplying the same amount of water to the rag 50. Thus, the water is completely distributed over the rag 50, and then the water passing into the rag can drain onto the floor. This may increase cleaning efficiency.

[0139] The water outlet 470 may include a plurality of flow openings 474. In this case, the absorbing element 476 can be made in the form of threads for passing through a plurality of flow openings 474 and winding a water outlet 470.

[0140] Although not shown, the water outlet 470 may have one or more guide channels to allow radial passage of water passing through the flow openings 474.

[0141] The water storage unit 440 may further include a limiter 452 to limit the rotation of the water flow controller 460 when the gasket 466 is in contact with the contact portion 412. When the water flow controller 460 is rotated in the same direction, the second element 464 contacts the limiter 452 , water flow controller 460 may no longer rotate. In this position, the gasket 466 can be held in contact with the contact portion 412.

[0142] The operation of the water flow controller will be described below.

[0143] FIG. 7 is a sectional view illustrating a flow of water in a water tank in accordance with a first embodiment of the present disclosure; FIG. 8 is a sectional view illustrating a blocked flow of water in a water tank in accordance with a first embodiment of the present disclosures.

[0144] As shown in FIGS. 1-7, to enable the flow of water from the water storage unit 440, the water flow controller 460 can rotate in a first direction.

[0145] As the angle of rotation of the water flow controller 460 in the first direction increases, the gasket 466 is positioned at an increasing distance from the contact portion 412, and thus the distance between the gasket 466 and the contact portion 412 may increase.

[0146] In contrast, when the rotation angle of the water flow controller 460 in the second direction opposite to the first direction increases, the gasket 466 becomes closer to the contact portion 412, and thus, contact between the sealing gasket 466 and the contact portion 412 can occur when a given angle of rotation of the controller 460 flow rate.

[0147] In this embodiment, since the distance between the gasket 466 and the contact portion 412 increases, the amount of water flow from the water storage unit 440 may increase. That is, the user can rotate the water flow controller 460 in a first direction or a second direction to adjust the amount of water flow.

[0148] As shown in FIG. 7, when the rotation of the water flow controller 460 in the first direction provides a location at a distance of the gasket 466 from the contact portion 412, water from the water storage unit 440 may pass through the water passage 414 for the water guide 413 and, then pass between the gasket 466 and the contact portion 412, and then through the flow opening 474.

[0149] When the water storage unit 440 has a level above the height of the guide 413, water can pass between the guide 413 and the first element 462 and then pass between the gasket 466 and the contact portion 412.

[0150] Then, water from the flow opening 474 can pass into the absorption element 476 and then can pass to a rag 50 connected to the water tank 40.

[0151] To increase the amount of water flow in the position of FIG. 7, the user can rotate the water flow controller 460 in the first direction. To reduce the amount of water flow in the position of FIG. 7, the user can rotate the water flow controller 460 in a second direction.

[0152] As shown in FIG. 8, to block the flow of water from the water storage unit 440, the user can rotate the water flow controller 460 in a second direction until the rotation of the water flow controller 460 stops. Moreover, when the sealing gasket 466 is in contact with the contact portion 412, the communication between the flow opening 474 and the water storage unit 440 may be blocked.

[0153] Using this embodiment, the water flow controller 460 can adjust the amount of water flow from the water storage unit to bring water to the rag based on the amount set by the user. At the same time, the water flow controller can rotate to provide easy adjustment by the user of the water flow controller.

[0154] Furthermore, using a water flow regulator, the water flow may be blocked to stop the water supply to the rag when the water supply to the rag is optional.

[0155] Although in the above embodiment, the hole 411, the contact portion 412 and the guide 413 are formed in the housing plate 410, the present disclosure is not limited to this. For example, a hole 411, a contact portion 412, and a guide 413 may be formed in a single chamber casing that acts as an independent chamber for storing water. In this case, the plate 410 of the housing may have another hole connected to the hole 411.

[0156] Furthermore, although in the above embodiment, the seal is in contact with the contact portion, the present disclosure is not limited to this. For example, an outlet may be omitted, and the opening may function as a flow opening, and thus the sealing gasket may come into contact with the edge of the opening.

[0157] FIG. 9 is a perspective view of a portion of an outlet of a water tank in accordance with a second embodiment of the present disclosure.

[0158] This second embodiment may be similar to the first embodiment except that a flow opening is formed in the plate of the housing. Thus, only features of the second embodiment will be described below.

[0159] As shown in FIG. 9, in this second embodiment, the housing plate 410 may have a flow opening 416 for the flow of water. The flow hole 416 may be located in an area defined by the contact portion 411.

[0160] In this embodiment, a structure located in an area defined by the contact portion 411 and having a flow opening 416 may be referred to as an outlet.

[0161] In one example, in the region defined by the contact portion 411, a series of flow openings 416 may be formed. In addition, the flow opening 416 may have an absorbing element 417. The absorbing element 417 may be made in the form of threads passing through the number of flow openings 416 and wrap the housing plate 410.

[0162] Although not shown, the housing plate 410 may have one or more guide channels to allow radial passage of water passing through the flow opening 416.

[0163] FIG. 10 is a perspective view of a water tank in accordance with a third embodiment of the present disclosure; FIG. 11 is a sectional view taken along line A-A in FIG. 10.

[0164] This third embodiment may be similar to the first or second embodiment, except that the water tank has a number of water storage units. Thus, only features of this third embodiment will be described below.

[0165] As shown in FIGS. 10 and 11, in this embodiment, the water tank 60 may include a housing plate 610 and a plurality of water storage units 620 and 630.

[0166] The plurality of water storage units 620 and 630 may include a first water storage unit 620 and a second water storage unit 630.

[0167] In one example, the first water storage unit 620 and the second water storage unit 630 may be spaced horizontally from each other. Between the first water storage unit 620 and the second water storage unit 630, a connection (22 in FIG. 1) may be located. In addition, each of the water storage units 620 and 630 may have connecting elements (421 and 422 in FIG. 3).

[0168] The first water storage unit 620 may have a water flow controller 460. The water flow controller 460 may be similar to the water flow controller 460 in the first embodiment with respect to a function, design and / or relative location with the first water storage unit 620.

[0169] The second water storage unit 630 may have a water inlet 631 and a cover 632 for opening or closing the water inlet 631.

[0170] The first water storage unit 620 and the second water storage unit 630 may be in fluid communication with each other through a connecting channel 650.

[0171] With respect to the water tank 60, the H1 level of the lowest point 652 of the connecting channel 650 may be higher than the highest level H2 of the contact portion 412. In addition, the H1 level of the lowest point 652 of the connecting channel 650 may be higher than the level of the flow opening as the final destination of the flow water.

[0172] In this case, the lowest point 652 of the connecting channel 650 may be a meeting point with the first block 620 for storing water.

[0173] Using this embodiment, in which the H1 level of the lowest point 652 of the connecting channel 650 is higher than the highest level H2 of the contact portion 412, the H1 level of the lowest point 652 of the connecting channel 650 is higher than the level of the flow opening as the final destination of the water flow, water from the second block 630 for storage can easily and smoothly pass into the first block 620 for storage.

[0174] Using this embodiment, in which the water tank has a series of water storage units, the water storage volume is increased, thereby increasing the time and / or cleaning area, and / or reducing the frequency of filling the water storage unit with water.
