Even in order to prevent interference between the water tank 40 and the wheels 23 and 214, the water tank 40 may be disposed at the rear of the front wheel 214 and in front of the rear wheel 23.

That is, when the water tank 40 is coupled to the nozzle assembly 20, the water tank 40 may be disposed between the front wheel 214 and the rear wheel 23. Even the water tank 40 may be disposed between the air inlet 212 and the rear wheel 23.

The water tank 40 can include a body plate 410.

A flat fabric 50 can be placed on the bottom of the body plate 410.

The body plate 410 can support the connecting portion 22.

The water tank 40 can further include a coupling device coupled to the nozzle assembly 20.

The coupling device can include a first coupling unit 421 and 422 coupled to the nozzle body 21.

The first coupling units 421 and 422 may extend upward from the body plate 410. In order to securely couple the water tank 40 to the nozzle body 21, a plurality of first coupling units 421 and 422 may be mounted on the body plate 410. The plurality of first coupling units 421 and 422 may be separated from each other in the left-right direction.

The nozzle body 21 may include a receiving portion 220 to receive the first coupling units 421 and 422. The receiving portion 220 may be recessed in the nozzle body 21.

When the plurality of first coupling units 421 and 422 are disposed on the water tank 40, a corresponding number of receiving portions 220 may be disposed on the nozzle body 21. The plurality of receiving portions 220 may be separated from each other in the left-right direction.

The nozzle body 21 may include a hook member 230 that is coupled to the first coupling units 421 and 422, respectively, when the first coupling units 421 and 422 are received in the receiving portion 220, respectively.

The hook element 230 can be fixed to the nozzle body 21. Each of the hook elements 230 can protrude at least partially from each of the receiving portions 220.

During insertion of each of the first coupling units 421 and 422 into each of the receiving portions 220, the hook members 230 are elastically deformed by each of the first coupling units 421 and 422, and then with each of the first coupling units 421 and 422 Each hook receiving portion (not shown) is aligned so that the hook member 230 can be received in each of the hook receiving portions (not shown) of each of the first coupling units 421 and 422.

In one embodiment, the hooks of each of the second coupling units 430 and 431 may contact the connecting portion 22 at a top surface thereof.

Since the connecting portion 22 is located between the second coupling units 430 and 431, the nozzle assembly 20 can be prevented from being removed from the water tank 40 while the nozzle assembly 20 is moving in the right or left direction.

That is, when the force of moving the nozzle assembly 20 may be applied to the nozzle assembly 20 in a state where the connecting portion 22 is not positioned between the second coupling units 430 and 431, if the water tank 40 and the nozzle assembly are When the coupling force between 20 is less than the friction between the fabric 50 attached to the water tank 40 and a floor area material, the nozzle assembly 20 can be removed from the water tank 40.

However, with this embodiment, the force of moving the nozzle assembly 20 can be applied to one of the plurality of second coupling units 430 and 431 while the nozzle assembly 20 is moving in the right or left direction. Therefore, the nozzle assembly 20 can be prevented from being removed from the water tank 40 regardless of the frictional force between the fabric 50 attached to the water tank 40 and the floor area material.

The water tank 40 may further include a water storage unit 440 to supply water to the fabric 50.

The water storage unit 440 may be formed of a chamber case 441 and a part of the body plate 410 integrally formed with the body plate 410.

Even, the chamber case 441 may be integrally formed with one of the plurality of second coupling units 430 and 431, or may be separated from the plurality of second coupling units 430 and 431.

Figure 5 is a cross-sectional view showing the internal structure of a water tank according to a first embodiment of the present invention; and Figure 6 is a perspective view of a water outlet according to a first embodiment of the present invention.

Referring to 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.

In one embodiment, the water inlet 442 may be formed in the chamber casing 441.

The water storage unit 440 may further include a water flow regulator 460. That is, the water flow regulator 460 can regulate the flow of water supplied to the fabric 50.

The water flow regulator 460 can block the flow of water supplied to the fabric 50. Even water flow regulator 460 can vary the flow of water supplied to fabric 50.

Water flow regulator 460 can be rotatably coupled to water storage unit 440. In one embodiment, the water flow regulator 460 can be coupled to the chamber housing 441. The rotation of the water flow regulator 460 can change the water flow.

The water flow regulator 460 can include a first element 462 that is rotatably coupled to the water storage unit 440 and a second element 464 that is coupled to the first element 462. The user can hold and rotate the second element 464.

The first element 462 can be inserted into the water storage unit 440. The water storage unit 440 has an engagement rib 450 that engages with the first member 462. The first element 462 can have an outer circumference that is coupled to the outer circumference Engaged to the inner circumference of the engagement rib 450, in one embodiment, the inner circumference and the outer circumference may be in meshing engagement with one another.

In order to spirally engage the engagement rib 450 with the first member 462, the engagement rib 450 may be formed in a ring shape, and the first member 462 may be formed in a cylindrical shape. The inner circumference of the engagement rib 450 and the outer circumference of the first member 462 have threads.

The second element 464 can be coupled to the first element 462 to surround the engagement rib 450. The user can hold or rotate the second member 464 in a clockwise or counterclockwise direction.

The water flow regulator 460 can include a seal 466. The water storage unit 440 can include a contact portion 412.

In one embodiment, the seal 466 can be disposed on the first member 462. In one embodiment, the contact portion 412 can be disposed on the body plate 410.

The seal 466 can contact the contact 412 as the water flow regulator 460 rotates to block the flow of water.

The water storage unit 440 further includes an opening 411; a water outlet 470 can be coupled to the opening 411. In one embodiment, the opening 411 may be formed in the body plate 410; the opening 411 may serve as a water flow channel.

The water outlet 470 can include a water flow aperture 474. Even the contact portion 412 can surround the opening 411 and the water flow hole 474.

Therefore, when the seal 466 contacts the contact portion 412, the communication between the water flow hole 474 and the inner chamber of the water storage unit 440 can be blocked, whereby the water in the water storage unit 440 does not flow into the water flow hole 474.

Conversely, when the seal 466 is separated from the contact portion 412, the water flow hole 474 can be allowed to communicate with the inner chamber of the water storage unit 440, and the water in the water storage unit 440 can be between the seal 466 and the contact portion 412. The flow then flows into the water flow holes 474.

The contact portion 412 may protrude from the body plate 410 or may be recessed in the body plate 410. As shown in FIG. 5, in one embodiment, the contact portion 412 can protrude from the body plate 410.

The contact portion 412 may form an annular shape, and the seal 466 may correspondingly form a ring shape.

The water storage unit 440 further includes a guide portion 413 to guide the rotation of the water flow regulator 460. In one embodiment, the guide portion 413 can extend upward from the body plate 410. In one embodiment The guide portion 413 may be formed in a cylindrical shape. The guiding portion 413 may have a height greater than the height of the contact portion 412.

As described above, the first member 462 is engaged with the engagement rib 450 in a spiral manner such that the rotation of the first member 462 causes the first member 462 to move vertically.

In this case, the guiding portion 413 can guide not only the rotation of the first member 462 but also the vertical movement of the first member 462.

The guiding portion 413 may have a height greater than the height of the contact portion 412. Thus, when the seal 466 is positioned in the area defined by the guide 413, the rotation of the first element 462 can cause contact or separation between the contact 412 and the seal 466.

When the seal 466 is separated from the contact portion 412, the guide portion 413 can prevent rapid water flow between the seal 466 and the contact portion 412.

When the water storage unit 440 has a water level higher than the height of the guide portion 413, water in the water storage unit 440 may flow between the inner circumference of the guide portion 413 and the outer circumference of the first member 462, and then at the seal 466 and Flow between the contact portions 412.

The guiding portion 413 may have a water passing hole 414 formed therein to allow water to flow between the seal 466 and the contact portion 412 when the water storage unit 440 has a water level lower than the height of the guiding portion 413.

In one example, the water permeable aperture 414 can have a minimum water level that substantially fills the top surface of the body plate 410.

In addition, a plurality of water passing holes 414 may be formed in the guiding portion 413, and the plurality of water passing holes 414 may be disposed along the circumference of the guiding portion 413.

In one embodiment, the water outlet 470 can be made of a rubber material and can be coupled to an opening 411 in the body plate 410. The water outlet 470 can include a coupling portion 472 coupled to the opening 411; a water flow aperture 474 can be formed in the coupling portion 472.

In order to prevent rapid water flow through the water flow holes 474, an absorbing member 476 for absorbing water is disposed in the water flow holes 474. Therefore, water remaining in the absorbing member 476 can be supplied to the fabric 50.

When the absorbing element 476 is absent, water can flow directly to the water flow aperture 474 and then to the fabric 50. In this case, the water flowing into the fabric 50 may fall to the floor area before the water completely spreads the fabric 50, which may reduce the cleaning efficiency.

Conversely, as shown in this embodiment, when the absorbing member 476 is present in the water flow hole 474, the absorbing member 476 can allow water to stay therein, thus increasing the time for supplying the same amount of water to the fabric 50, so that the water can be completely Dispersed on the fabric 50, then the water flowing into the fabric 50 can fall to the floor area, which can improve the cleaning efficiency.

The water outlet 470 can include a plurality of water flow holes 474. In this case, the absorbing element 476 can be implemented as a thread to pass through the plurality of water flow holes 474 and wrap around the water outlet 470.

Although not shown, the water outlet 470 can have one or more guide channels to allow rapid diffusion of water through the water flow holes 474.

The water flow regulator 460 can further include a limiter 452 to limit rotation of the water flow regulator 460 when the seal 466 contacts the contact portion 412. When the water flow regulator 460 rotates in one direction and the second element 464 contacts the limiter 452, the water flow regulator 460 is no longer rotating. In this state, the seal 466 can remain in contact with the contact portion 412.

In the following, the operation of the water flow regulator will be explained.

Figure 7 is a cross-sectional view illustrating a flow of water in a water tank according to a first embodiment of the present invention; and Figure 8 is a cross-sectional view illustrating a flow of water blocked in a water tank according to a first embodiment of the present invention.
