Intelligent water-mixed mechine consists of temperaturesensor,microcomputor-controlled mechine,drive equipment,electromagnetic valve and water-mixed pitcher. In order to ensure that the cold and hot water can be fully mixed,the eddy control mode adopts the front and back lock mode employed on the air. The temperature sensor gathers exit and entrance water temperature value in fixed time and send the value to micro-computer controlled mechine,which will process it and compare it with the constant temperature.The mixed-water temperature will be controlled by opening or closing the different electromagnetic valve according to the temperature difference. thus,the water temperature at the exit will be constant in repeated comparison and adjustment.
