[0028] Specifically, the structure of water distribution valve 2 has diversity, and the dish-washing machine can selectively set the water distribution function according to the needs, if the structure that water distribution valve body 21 and sink 1 are integrally formed in the prior art is used, then the structure of water distribution valve 2 is limited, and cannot be flexibly replaced according to the needs of equipment. Therefore, the detachable fixed connection between water distribution valve body 21 and sink 1 of the utility model, when replacing water distribution valve body 21, as long as the replaced water distribution valve body 21 is matched with the mounting interface of sink 1, can be installed on sink 1, so that different types of water distribution valve 2 can be replaced according to the needs, to meet the needs of the change of multiple water distribution modes.

[0029] Then refer to Figure 2 And Figure 3, the bottom of the sink 1 is provided with a first limiting member 13 which is integrally injection molded with the sink 1, the water distribution valve body 21 comprises a first valve body 211, a connecting member 212 and a second valve body 213, the first valve body 211 is matched with the first limiting member 13, the second valve body 213 is arranged outside the first limiting member 13, and the first valve body 211 is connected with the second valve body 213 through the connecting member 212.

Specifically, the driving mechanism 24 is arranged as a driving motor, the shunt hole 2611 and the water outlet 11 are arranged as a circular hole structure, the water outlet 11 is provided with three, and the shunt hole 2611 is provided with two, water flows to the valve cavity of the water distribution valve body 21 through the water inlet 23, and flows to the water outlet 11 through the water distribution disc 26, is transported to the spray arm through the connecting pipe, the water distribution disc 26 controls the flow direction and distribution ratio of water flow by the position change of the shunt hole 2611 in the rotating process to realize the distribution of water flow to different waterways in different cleaning modes. It should be noted that the number of the shunt hole 2611 and the water outlet 11 described above is only exemplary, and a person skilled in the art can also set it according to actual needs. The shunt hole 2611 can also be arranged as other structures in addition to the circular hole structure, and the above adjustment is within the protection scope of the utility model.

[0034] Further, it should be noted that although the above is described in combination with "the driving mechanism 24 is arranged as a driving motor", but this is not a limitation, and a person skilled in the art can also use other driving mechanisms 24, as long as it can drive the water distribution disc 26 to rotate, and the water distribution valve body 21 is matched with the driving mechanism 24 for assembly, and the above adjustment is within the protection scope of the utility model.

[0035] Continuing as shown in Figure 3 The water distribution disc shaft 262 is provided with an elastic member 27, and the two ends of the elastic member 27 are respectively abutted with the water distribution disc shaft 262 and the connecting shaft 25, so that the water distribution disc 26 can be tightly attached to the lower end surface of the sink 1, avoiding water leakage. Specifically, the elastic member 27 is arranged as a spring, and the spring is sleeved on the water distribution disc shaft 262.

[0036] Continuing as shown in Figure 3 The connecting shaft 25 and the water distribution valve body 21 are provided with a second sealing member 28 to ensure the sealing performance between the two, avoiding water leakage. Specifically, the second sealing member 28 is arranged as a rubber ring, of course, the second sealing member 28 can also adopt other structures in addition to the rubber ring, as long as it can play a sealing role, and the utility model does not make any limitation on this.

[0038] Further, in order to improve the flow efficiency of the water flow in the flow guide column, a flow guide structure (not shown in the figure) is arranged in the flow guide column. Specifically, the flow guide structure is arranged as a spiral structure, so that after the water flow enters the flow guide column, it spirals upward to the water outlet 11 under the action of the flow guide structure, improving the flow guide efficiency. It should be noted that although the above is described in combination with "the flow guide structure is arranged as a spiral structure", but this is not a limitation, and those skilled in the art can also arrange other flow guide structures according to actual needs, as long as they have the flow guide effect.
