As shown in the figure, the circuit is directly connected to 220V AC, and after being stepped down by the transformer, the rectifier diode rectifies the output to a stable DC voltage. The main circuit is controlled by the IC to realize the function of hot and cold drinking water. The circuit is simple and practical.
