When the warm water dispenser is in use, press the heating switch, and the power supply provides power for the “insulation” indicator to indicate power. At the same time, the power supply is divided into two ways: one way constitutes a heating circuit, so that the electric heating tube is energized and heated to heat up; the other way provides a voltage for heating indication of the "heating" indicator light. When the water in the hot tank is heated to the set temperature, the thermostat contacts are disconnected, the heating and heating indication circuit power is cut off, the "heating" indicator is extinguished, and the electric heating tube stops heating. When the water temperature drops to the set temperature, the thermostat contacts are connected to the power supply circuit, and the electric heating tube is reheated, so that the water temperature is maintained at 85-95 ° C. The warm water dispenser circuit is a double protection component. When the water dispenser is over temperature or short circuit fault occurs, the overheating fuse automatic melting or manual reset thermostat automatically disconnects the heating circuit power supply to protect the water. The over-temperature fuse is a one-time thermal protection component, which cannot be reset. After the fault is removed, replace the new over-temperature fuse according to the original model specification, and then manually reset the reset button of the thermostat by hand. The contact can be closed again. .
