Description

TECHNICAL FIELD

[0001] The utility model relates to a dishwasher technical field especially relates to a distributor and its dishwasher. BACKGROUND

[0002] The intelligent dispenser of part dishwasher at present integrates the dishwashing liquid cavity for containing dishwashing liquid, and the dishwashing liquid cavity is provided with an exhaust hole and a liquid outlet hole. The exhaust hole has two functions: one is to exhaust the gas generated when the dishwashing liquid in the dispenser cavity is heated during the washing process of the dishwasher; the other is to balance the air pressure inside and outside the dishwashing liquid cavity during the liquid pumping process of the peristaltic pump to avoid the formation of negative pressure affecting the stability of the liquid pumping flow. However, during the washing process, the micro-pressure high-temperature steam generated in the inner cavity of the dishwasher enters the dishwashing liquid cavity through the exhaust passage of the dispenser, forms condensate water on the inner wall through heat exchange, and accumulates after multiple cycles, dilutes the concentration of the detergent in the cavity, and affects the performance of the dishware washing.

[0003] To solve the above problems, some manufacturers add a flip cover outside the exhaust hole of the dispenser to block water and steam from entering, but the actual effect is not good. Some manufacturers also add two valves, "one in and one out", on the dispenser shell. Although this scheme can solve the problem of condensate water entering, it increases the cost and requires a higher opening pressure for the valve body. The "air inlet valve" needs to be opened during the liquid pumping process of the peristaltic pump and needs to remain closed under the pressure of the inner cavity during the washing process.
