In addition, the detergent box housing 140 may be formed with a guide plate 124 for guiding the washing water passing through the detergent box 120 to the washing tank 14 or the reservoir 13, wherein the guide plate has a washing water flow direction. In order to be limited in one direction, it may be inclined at a predetermined angle.

A plurality of small holes 114 may be formed in the dispenser 110. In this case, the washing water is injected into the detergent box 120 through the small holes as well as the nozzle 130. In particular, the plurality of small holes 114 may be formed in a section in which the flow direction of the washing water flows from the upstream to the downstream of the first flow passage 116 on the second flow passage 118, and in this embodiment, the first rib 113. ) And the second rib 115.

Referring to FIG. 6, a plurality of nozzles 130 may be formed adjacent to the boundary ribs 111 extending along the circumference of the dispenser 110. In this case, the positions of the nozzles 130 may be different from each other. Can be formed. In particular, the washing water passing through the first flow path 116 collides with each other in the section in which the boundary ribs 111 are formed, and is formed in a section where the change of direction occurs, that is, downstream of the first flow path 116 to induce a change in the echo of the washing water. The nozzles h4, h5, and h6 formed in the section to be formed are nozzles h1, h2, h3, and H3 formed in a section in which the flow direction of the washing water on the second flow path 118 is directed from the downstream side to the upstream side of the first flow path. It is preferable to be located closer to the delimiting rib 111 relative to the h7, h8, h9). (D2 <D1) The reason why the nozzles 130 are arranged in this manner is effective in reducing the deviation between the mass flows of the washing water sprayed through the nozzles 130.

In FIG. 7, a graph (a) shows nozzles h4, h5, and h6 located in a section in which the wash water passing through the first flow path 116 and the direction change are made among the sections in which the boundary ribs 111 are formed. The flow direction of the wash water on 118 is located closer to the delimiting ribs relative to the nozzles h1, h2, h3, h7, h8, and h9 formed in the section from the downstream side of the first flow passage toward the upstream side. In this case, the flow rate of the washing water sprayed through each nozzle 130 is measured. On the other hand, if the distance between the nozzles h1 to h8 and the delimiting ribs 111 is equal to D2, the graph c delimits all the nozzles h1 to h8. This is the case where the spacing between the ribs 111 is the same as D1. As can be seen from the comparison of the graphs, compared to the graph (b) or the graph (c), the flow rate of the washing water sprayed through the nozzles 130 is smaller than that of the graph (b) or the graph (c). When the flow rate of the graph (b) is compared with the graph (c), the nozzle (h5) shows a significant deviation between the different nozzles according to the distance between the nozzle and the boundary rib 111, in the case of the graph (a) It can be seen that the difference between the other nozzles is not large due to the intermediate value between (b) and graph (c).
