As illustrated in FIGS. 4 through 6, the fixing unit 60 includes the mounting structure for fixing the spray unit 70. Hereinafter, the mounting structure will be described in detail.

The mounting groove 64 into which the connection hose 71 is inserted, may be provided at the fixing unit 60. According to an embodiment of the present disclosure, the fixing unit 60 may include at least one side rib 61. The at least one side rib 61 extends to an upper portion of the fixing unit 60 and prevents the connection hose 71 of the spray unit 70 from being deviated from the outer side of the fixing unit 60.

Also, the mounting structure may further include an upper rib 62 that fixes a top surface of the connection hose 71 of the spray unit 70 so as to prevent vertical movement of the spray unit 70. The upper rib 62 may be placed at an upper portion of the connection hose 71 and may protrude to cover a portion of a top surface of the mounting groove 64.

Also, the mounting structure may further include a lower rib 63 that supports a bottom surface of the connection hose 71 of the spray unit 70 so as to support a bottom surface of the spray unit 70.

According to an embodiment of the present disclosure, the side rib 61 and the upper rib 62 may be disposed to cross each other. That is, when a region in which the side rib 61 is placed is defined as a first region r1 and a region in which the upper rib 62 is placed is defined as a second region r2, the first region r1 and the second region r2 may be different from each other. The upper rib 62 may be disposed at a portion where the side rib 61 is not placed. According to an embodiment of the present disclosure, three upper ribs 62a, 62b, and 62c and two side ribs 61a and 61b may be provided. According to the drawings, the lower rib 63 is provided at both ends of the side ribs 61a and 61b. However, embodiments of the present disclosure are not limited thereto.

The plurality of nozzles 77 and 78 may be coupled to the spray portion 65 of the fixing unit 60. The spray portion 65 may be provided to protrude in an inward direction of the rotating tub 30. The nozzles 77 and 78 are coupled to a communicating pipe 68 provided to protrude from the spray portion 65. This will be described later.

FIG. 7 is an enlarged view of nozzles of the spray unit of the washing machine of FIG. 1, and FIG. 8 is an enlarged view of another side of the fixing unit of the washing machine of FIG. 1.

As illustrated in FIGS. 7 and 8, the nozzles 77 and 78 of the spray unit 70 may be coupled to the spray portion 65. Each of the other sides of the nozzles 77 and 78 that are respectively coupled to the connector 74 is coupled to the spray portion 65. The other side of the connector 74 may be coupled to a guide pipe 75 for guiding coupling of the connector 74 and the connection hose 71. The connector 74 may be inserted into the guide pipe 75, and a holder 76 for fixing the guide pipe 75 and the connector 74 may be coupled onto a surface of the guide pipe 75.

A bottom surface 69a of the spray portion 65 may be provided to protrude in an upward direction compared to the mounting structure so as to prevent washing water from spattering on the outer side of the fixing unit 60. Also, sidewalls 69b of the spray portion 65 may be provided to protrude outward compared to the communicating pipe 68. This is to prevent washing water from spattering on the outer side of the fixing unit 60.

Also, washing water may be widely sprayed into the rotating tub 30 due to a guide portion 69c that is provided to be widened as getting closer to its lower side around a communicating hole 69d that communicates with the communicating pipe 68 and faces an inner side of the rotating tub 30.

FIG. 9 is an enlarged view illustrating a state in which the spray unit is disassembled from the fixing unit of the washing machine of FIG. 1, according to another embodiment of the present disclosure.

As illustrated in FIG. 9, according to another embodiment of the present disclosure, at least a portion of the mounting structure may be provided to be inclined in an upward direction from the first nozzle 77 to the second nozzle 78. According to the other embodiment of the present disclosure, a length of a lower rib 163 at which it protrudes upward, may be provided to be increased as it gets closer to the second nozzle 78. That is, when a length at which a lower rib 163a close to the first nozzle 77 protrudes upward, is defined as dl and a length at which a lower rib 163b close to the second nozzle 78 protrudes upward, is defined as d2, a relationship of d1<d2 may be established. This is to mount the connection hose 71 so that washing water can be smoothly transferred to the second nozzle 78 placed far from the integrated hose 72. Since the lower rib 163 further protrudes as it gets closer to the second nozzle 78, the connection hose 71 may be pressurized so that washing water can be smoothly transferred to the second nozzle 78.

In addition, the mounting structure may include an upper rib 162 and a side rib 161, as described above.

As described above, according to the embodiments of the present disclosure, a mounting structure in which a spray unit can be fixed by a fixing unit, is improved so that movement of the spray unit can be prevented when a washing machine operates and the spray unit can be assembled in a desired position of the washing machine. Accordingly, an additional fastening member for fixing the spray unit need not be prepared so that costs can be reduced and a process time can be reduced.

Although a few embodiments of the present disclosure have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the disclosure, the scope of which is defined in the claims and their equivalents.
