[0117] FIG. 13 illustrates a state before the water supply pipe and the drain pipe are connected to the water supply and drainage device in the cleaning device according to one embodiment. FIG. 14 illustrates a state after the water supply pipe and the drain pipe are connected to the water supply and drainage device in the cleaning device according to one embodiment. FIG. 15 illustrates a state in which a release portion of the water supply pipe connecting member is pushed in the cleaning device according to one embodiment. FIG. 16 illustrates a state in which a fixation of the water supply pipe connecting member to the water supply pipe is released in the cleaning device according to one embodiment.

[0118] Referring to FIG. 13, the water supply pipe 340 and the drain pipe 350 may be inserted into the housing 330 through the first coupling hole 332 and the second coupling hole 333, respectively. A user can pass the water supply pipe 340 and the drain pipe 350 through the first coupling hole 332 and the second coupling hole 333 by moving the water supply pipe 340 and the drain pipe 350 upward, respectively. One end of the water supply pipe 340 passing through the first coupling hole 332 may be inserted into and coupled to the first water supply port 332a of the water supply pipe connecting member 310. One end of the drain pipe 350 passing through the second coupling hole 333 may be connected to the drain pipe connecting member 320.

When the first release portion 311 is spaced apart from the first water supply pipe connecting portion 312 by the gap g, the water supply pipe connecting member 310 may fix the water supply pipe 340 so as to prevent the water supply pipe 340 from being separated from the water supply pipe connecting member 310.

[0120] Referring to FIG. 14, the housing 330 may include a water supply pipe support portion 337 provided to support an outer surface of at least a portion of the water supply pipe 340 adjacent to the first release portion 311 or the first water supply port 332a or the first water supply pipe connecting portion 312. When the water supply pipe 340 is coupled to the water supply pipe connecting member 310, at least a portion of the water supply pipe 340 may be supported by the water supply pipe support portion 337. The water supply pipe support portion 337 may form the first coupling hole 332. The water supply pipe support portion 337 may form a boundary or a side surface of the first coupling hole 332. By supporting at least a portion of the water supply pipe 340 by the water supply pipe support portion 337, the at least a portion of the water supply pipe 340 may be fixed so as not to move in the horizontal direction.

[0121] When the water supply pipe 340 is pulled horizontally, a horizontal force may be applied to the water supply pipe connecting member 310 connected to the water supply pipe 340, this may cause damage to the water supply pipe connecting member 310. Particularly, the water supply pipe bent portion 315 of the water supply pipe connecting member 310 may be damaged. According to the present disclosure, the horizontal movement of the water supply pipe 340 may be prevented by the water supply pipe support portion 337, and thus it is possible to prevent a horizontal external force from being applied to the water supply pipe connecting member 310. Accordingly, it is possible to prevent damage to the water supply pipe connecting member 310 in advance.

[0122] The housing 330 may include a drain pipe support portion 338 provided to support an outer surface of at least a portion of the drain pipe 350. The drain pipe support portion 338 may form the second coupling hole 333. The drain pipe support portion 338 may have substantially the same structure as the above-mentioned water supply pipe support portion 337 and thus a description thereof will be omitted.

[0123] Referring to FIG. 15, in order to release the fixation of the water supply pipe 340 fixed by the water supply pipe connecting member 310, a separation member 380 may pass through the first separation hole 335 and push the first release portion 311. It is sufficient that the separation member 380 is a component provided to push the first release portion 311 upward. There is no limitation on shape, structure, or function of the separation member 380.

[0124] The first release portion 311 of the water supply pipe connecting member 310 may be exposed to the outside through the first separation hole 335. As mentioned above, in order to release the fixation of the water supply pipe connecting member 310 to the water supply pipe 340, it is required that the first release portion 311 be pushed. Accordingly, the first release portion 311 is exposed to the outside through the first separation hole 335, and thus the first release portion 311 may be easily pushed using the separating member 380 without the hassle of disassembling the housing 330.

[0125] When the first release portion 311 is pushed upward by the separation member 380 to be in contact with the first water supply pipe connecting portion 312, the fixation of the water supply pipe connecting member 310 to the water supply pipe 340 may be released. As shown in FIG. 16, the water supply pipe 340 in which the fixation thereof is released may move downward by gravity or user force, and the water supply pipe 340 may be separated to the outside of the housing 330 through the first coupling hole 332.

[0126] FIGS. 15 and 16 illustrate a process of separating the water supply pipe 340 coupled to the water supply pipe connecting member 310. As mentioned above, the drain pipe connecting member 320 and the drain pipe 350 have substantially the same structure and function as the water supply pipe connecting member 310 and the water supply pipe 340 and thus a description thereof will be omitted.

[0145] The first separation hole and the second separation hole may be spaced apart from each other in the horizontal direction.

[0146] The water supply pipe connecting member and the drain pipe connecting member may be disposed adjacent to a rear surface of the station.

[0147] The water supply pipe connecting member and the drain pipe connecting member may be disposed above the water supply tank and the sewage tank.

[0148] The housing may include a first portion protruding upward from an upper surface of the station, and a second portion protruding rearward from the rear surface of the station.

[0149] As is apparent from the above description, a cleaning device may include a station configured to automatically supply and drain water, and the cleaning device may be configured to prevent a water supply pipe and a drain pipe from being separated from the station.

[0150] Further, a cleaning device may include an improved structure configured to prevent damage to a connecting member provided to connect a water supply pipe and a drain pipe to a station.

[0151] Further, a cleaning device may include a housing provided to accommodate a connecting member provided to connect a water supply pipe and a drain pipe to a station, and the cleaning device may connect the water supply pipe and the drain pipe to the connecting member or may separate the water supply pipe and the drain pipe from the connecting member without accessing an inside of the housing.

[0152] While the present disclosure has been particularly described with reference to exemplary embodiments, it should be understood by those of skilled in the art that various changes in form and details may be made without departing from the spirit and scope of the present disclosure.
