[0108] When a water supply pipe (340) is inserted into a water supply port formed at one end or the other end of a water supply pipe connecting member (310), the water supply pipe connecting member (310) may be provided to fix the water supply pipe (340). By being inserted in one direction with respect to the water supply pipe connecting member (310), the water supply pipe (340) coupled to the water supply pipe connecting member (310) may not be separated from the water supply pipe connecting member (310) even if the water supply pipe (340) is pulled in the other direction. That is, the water supply pipe connecting member (310) may fix the water supply pipe (340) coupled to the water supply pipe connecting member (310) so that the water supply pipe (340) is not separated.

[0109] The water supply pipe connecting member (310) may include a release member (311, 313) provided to release the fixation of the water supply pipe (340) fixed to the water supply pipe connecting member (310). The release member (311, 313) may release the fixation of the water supply pipe connecting member (310) by being pushed in the direction in which the water supply pipe (340) is coupled.

The second fixing release member (313) can release the fixation of the second water supply pipe connection member (314) by being pushed laterally. The laterally may refer to the direction in which the second fixing release member (313) approaches the second water supply pipe connection member (314).

[0114] Fig. 13 illustrates a cleaning device according to one embodiment before the water supply pipe and the drain pipe are connected to the water supply and drain device. Fig. 14 illustrates a cleaning device according to one embodiment after the water supply pipe and the drain pipe are connected to the water supply and drain device. Fig. 15 illustrates a cleaning device according to one embodiment when the fixing release part of the water supply pipe connection member is pushed. Fig. 16 illustrates a cleaning device according to one embodiment when the fixing of the water supply pipe connection member to the water supply pipe is released.

[0115] Referring to Fig. 13, the water supply pipe (340) and the drain pipe (350) can be inserted into the housing (330) by passing through the first coupling hole (332) and the second coupling hole (333), respectively. The 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), respectively, by moving them upward. One end of the water supply pipe (340) that has passed through the first coupling hole (332) can be inserted into and connected to the first water supply port of the water supply pipe connecting member (310). One end of the drain pipe (350) that has passed through the second coupling hole (333) can be connected to the drain pipe connecting member (320).

[0116] Referring to Fig. 14, when the water supply pipe (340) is connected to the water supply pipe connecting member (310), the first fixing release member (311) can be spaced apart from the first water supply pipe connecting member (312) by a predetermined gap (g) in the vertical direction or the vertical direction. When the first fixing release member (311) is spaced apart from the first water supply pipe connecting member (312) by the gap (g), the water supply pipe connecting member (310) can secure the water supply pipe (340) so that the water supply pipe (340) is not separated from the water supply pipe connecting member (310).

[0117] Referring to FIG. 14, the housing (330) may include a water supply pipe support member (337) provided to support an outer side surface of at least a portion of a water supply pipe (340) adjacent to the first fixing release member (311) or the first water supply port or the first water supply pipe connection member (312). When the water supply pipe (340) is connected to the water supply pipe connection member (310), at least a portion of the water supply pipe (340) may be supported by the water supply pipe support member (337). The water supply pipe support member (337) may form a first coupling hole (332). The water supply pipe support member (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 member (337), the at least a portion of the water supply pipe (340) may be fixed so as not to move in a horizontal direction.

[0118] 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), which may cause damage to the water supply pipe connecting member (310). In particular, the water supply pipe bending portion (315) of the water supply pipe connecting member (310) may be damaged. According to the present disclosure, horizontal movement of the water supply pipe (340) can be prevented by the water supply pipe support member (337), and thus, horizontal external force can be prevented from being applied to the water supply pipe connecting member (310). Through this, damage to the water supply pipe connecting member (310) can be prevented in advance.

[0119] The housing (330) may include a drain pipe support (338) provided to support at least a portion of the outer surface of the drain pipe (350). The drain pipe support (338) may form a second coupling hole (333). Since the drain pipe support (338) has substantially the same structure and function as the water supply pipe support (337) described above, a duplicate description will be omitted.

[0120] 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), the separation member (380) can pass through the first separation hole (335) and push the first fixation release member (311). The separation member (380) is sufficient as long as it can push the first fixation release member (311) upward, and there are no limitations in its shape, structure, or function.

[0121] The first fixing release portion (311) of the water supply pipe connecting member (310) can be exposed to the outside through the first separation hole (335). As described above, in order to release the fixation of the water supply pipe connecting member (310) to the water supply pipe (340), the first fixing release portion (311) must be pushed. However, since the first fixing release portion (311) is exposed to the outside through the first separation hole (335), the first fixing release portion (311) can be easily pushed using the separation member (380) without cumbersome work such as disassembling the housing (330).

[0122] When the first fixed release member (311) is pushed upward by the separation member (380) so that it comes into contact with the first water supply pipe connection member (312), the fixation of the water supply pipe connection member (310) to the water supply pipe (340) can be released. As illustrated in Fig. 16, the released water supply pipe (340) can move downward by gravity or the user's force, and can be separated from the housing (330) by passing through the first coupling hole (332).

[0123] In FIGS. 15 and 16, the separation process of the water supply pipe (340) connected to the water supply pipe connecting member (310) is described, but as described 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 therefore, the description thereof is omitted.

[0124] A cleaning device according to one embodiment includes a mop, a cleaner including a water tank for supplying water to the mop, and a station for mounting the cleaner.
