What is the principle of water dispenser heating body? Let's take a look at it with Xiaobian.
1. Press the heating switch, turn on the power supply, the heating circuit is turned on, the red heating indicator light is lit, and the electric heat pipe is heated. 2, the water temperature reaches the set temperature, automatically reset the thermostat automatically cut off the power supply, the red heating indicator is turned off, and the heat preservation state is transferred.
3. After power off, the water temperature gradually drops to the set temperature, the thermostat contact action is closed, the power supply is switched on, the red heating indicator is on, the electric heat pipe is heated again, and the water temperature in the drinking machine is controlled between 85-95℃. The compressed refrigeration water dispenser uses the temperature insurance control device, when the circuit is overheated, the protection device will automatically fuse or disconnect the circuit when overloaded, and play a protective role.
Warm water dispenser:
1, press the heating switch, the power supply for the "insulation" indicator to provide power, power indication. A heating circuit is formed to make the electric heat pipe heat up; The other provides voltage to the "heating" indicator for heating.
2, the water in the hot tank is heated to the set temperature, the thermostat contact is disconnected, the heating is cut off, the heating indicating loop power supply, the "heating" indicator light is extinguished, and the electric heat pipe stops heating.
3, the water temperature drops to the set temperature, the thermostat contact is connected to the power circuit, the electric heat pipe is heated again, so that the water temperature is kept between 85-95℃.
The warm water dispenser circuit adopts double protection elements. When the water dispenser overtemperature or short-circuit fault occurs, the overtemperature safety device automatically melts or manually resets the thermostat to automatically disconnect the heating circuit power supply, which plays a protective role. The overtemperature protector is a one-time thermal protection element, which cannot be reset. After troubleshooting, replace the overtemperature protector with a new one according to the original specifications, and then press the reset button of the thermostat manually by hand, and the contact can be closed to work again.
