What is the principle of drinking fountain? Why is there cold water or hot water?

A device for heating or cooling barreled purified water (or mineral water) and making it convenient for users to drink. Put bottled water on the top of the machine and use it with bottled water.

When in use, the direct-cooling cold and hot water dispenser obtains normal-temperature water from the water tank, and the water enters in two ways, one way enters the cold container to generate cold water after refrigeration, and the other way enters the hot water tank to generate hot water after heating.

After the refrigeration switch is pressed, the AC voltage is reduced by the power transformer, and after full-wave rectification by the rectifier diode and capacitor filtering, the DC voltage is output for the semiconductor refrigeration module refrigeration and fan exhaust, and the refrigeration indicator light is lit. Since the direct-cooling cold and hot water dispenser is not equipped with automatic temperature control, the refrigeration indicator light has been on since it was started.
