Can be formed. By varying the spraying direction of the nozzle unit 160, water is evenly sprayed into the detergent box 140, and as a result, all the detergent (d) is introduced together with water, so that the detergent residue is caught in the detergent box 140. Can be prevented.

Figure 6 illustrates a coupling structure of the rotary nozzle according to another embodiment of the present invention. Referring to FIG. 6, the rotating nozzle 150 may be supported by the bracket 170. That is, the rotary nozzle 150 is rotatably provided in the bracket 170, the bracket 170 in a state in which the rotary nozzle 150 is installed may be fixed to the detergent box housing 130. This form provides an advantage in the assembly or manufacturing process of the washing machine. That is, considering the narrow interior of the detergent box housing 130 and its complexity, the assembly of the rotating nozzle 150 to the bracket 170 rather than directly installing or assembling the detergent box housing 130 and This is because it is easy to install the bracket 170 in the state in which the rotating nozzle 150 is assembled to the detergent box housing 130.

Meanwhile, the bracket 170 may be coupled to the detergent box housing 130 in a detachable form. For this purpose, in this embodiment, the bracket 170 and the detergent box housing 130 are coupled in a hook manner. It has been heard (in this embodiment, the protrusion formed on the bracket 170 shows the hook coupling of the form to be combined with the distribution plate 110a), but is not necessarily limited to this, form that can be removable bracket (170) Of course, various implementations are possible.

The distribution part 710 may be provided with a predetermined pattern of water supply passages for guiding the water supplied through the water supply passage 23. In this embodiment, the distribution plate 710a and the distribution plate 710a protrude upward. The injection water supply passage is formed between the pair of flow path forming ribs 711 and 713. The jetting water supply passage has a first flow path 716 through which water supplied through the water supply flow path 23 primarily passes, and a second to change the flow direction of the washing water guided along the first flow path. A flow path 718 is included. Water guided along the first flow path 716 hits the delimiting rib 714 and is diverted in flow direction and then flows along the second flow path 218. In particular, the path of the water flowing along the second flow path 718 includes a section flowing in the opposite direction as when flowed along the first flow path 716. That is, after the water flowing through the connector 712 collides with the boundary rib 714 downstream of the first flow path 716 and the flow direction is changed, it is guided along the second flow path 718, the second flow path While being guided along the 718 and passing through the predetermined section, the flow direction of water is opposite to when passing through the first flow path 716, that is, the direction from the downstream side of the first flow path 716 to the upstream side.

In the present embodiment, the first flow path 716 is formed between the first ribs 711 and 713 formed to face each other, and the second flow path 718 is formed by the second rib bent from the first rib 713. 715 and a boundary rib 714 are formed, and the second flow path 718 is formed in a symmetrical structure on both sides of the first flow path 716.

In particular, the water supply passage 23 may be formed of two or more water supply passages, including a cold water supply passage for supplying cold water and a hot water supply passage for supplying hot water, and in this case, to independently control each water supply passage. Two or more water supply valves (not shown) may be provided.

The detergent box housing 730 may be provided with a cold water connector 712a connected to the cold water supply passage, and a hot water connector 712b connected to the hot water supply passage, and the laundry introduced through the cold water connector or the hot water connector. In any case, the water is guided along the first flow path 716 and then the flow direction is bent and flows along the second flow path 718. In particular, the second flow path 718 is formed on both sides of the first flow path 716, so that a portion of the wash water is guided along the second rib 718a on the downstream side of the first flow path 716 (flow) The other part is guided along the second rib 718b (see flow path II).

A plurality of discharge holes (H) is formed in the distribution plate (710a), the rotary nozzle 860 is coupled to the discharge hole (H). The rotary nozzle 860 is formed with an inlet 861 rotatably connected to the distribution plate 710a, and a spray hole 863 opened toward the detergent box 740, and the water introduced through the inlet 861. It includes a nozzle body 862 that provides a space for a predetermined time in the process of being injected through the injection hole 863. The rotary nozzle 860 may include the injection holes 163, 263, 363 and 463 and / or the protrusions 161, 261, 361 and 461 of the injection parts 160, 260, 360 and 460 shown in FIGS. 4A to 4D. The nozzle body 862 of the rotary nozzle 860 may be formed of the protrusions 161, 261, 361, and 461 in the above-described embodiments. There is a difference in that the rotating nozzle 860 is rotatably coupled to the distribution plate (110a).

On the other hand, the inlet 861 may be hooked with the distribution plate (110a) (see Figure 8), this structure allows the user to easily detach the rotary nozzle 860, the rotation of the nozzle 150 It is advantageous for maintenance repair. The nozzle body 862 may be formed in a dome shape protruding toward the detergent box 140.

Referring to FIG. 8, the injection hole 863 formed in at least one of the plurality of rotating nozzles 860 may have an opening direction of the side surface of the detergent box 140 so that water sprayed through it may contact the side of the detergent box. Can be set to correspond.

In addition, the shape of the injection hole 863 may be formed as a slit (see FIGS. 4A to 4C) so that the water sprayed through the rotary nozzle 860 may be spread out, that is, to form a thin water film. In this case, since the sprayed water reaches every corner of the detergent box 140, the detergent remaining in the detergent box 140 may be solved. According to an exemplary embodiment, any one of both side boundaries of the slit 163 may be formed to be more biased toward the inner wall side of the detergent box 140 than the other one (see FIG. 4B). In this case, it is possible to prevent the phenomenon of the residual detergent solidifying in the corner portion of the boundary of the bottom and sidewall of the detergent box 140.

On the other hand, the injection hole 863 may be formed at a position spaced apart a predetermined distance on the longitudinal axis of the inlet 861, this type of injection of water sprayed through the respective rotary nozzle 860 while the rotary nozzle 860 is rotated Provides variety to the direction.
