Internal water temperature setting mechanism

The invention relates to an internal water temperature setting mechanism. The internal water temperature setting mechanism comprises a first part, a second part and a water temperature setting device,wherein the first part is located in an uncovered dishwasher, comprises a teacup holder, an upper sprinkler, an upper shelf, a slide, a water inlet pipeline and a water inlet pump, and the water inlet pump is connected with the water inlet pipeline; the second part is located in the uncovered dishwasher, and comprises a lower shelf, a chopsticks box, a heater, a filter net, a lower sprinkler, a water softener and a rinsing agent adder; and the water temperature setting device is connected with the heater, used for receiving smudge reference quantities, and determines the heating target temperature of the heater based on thesmudge reference quantities, the more the smudge reference quantities are, the higher the determined heating target temperature is, and the heating target temperature is lower than a preset temperature threshold. According to the internal water temperature setting mechanism, the appropriate washing water temperature can be adaptively determined according to the smudge quantities in the uncovered dishwasher.
