Various water dispenser heating principle!

The working principle of water dispenser heating is to press the heating switch, switch on the power supply, the heating circuit is switched on, the red heating indicator light is lit, and the electric heat pipe is heated. When the water temperature rises to the set temperature, the automatic reset thermostat automatically cuts off the power supply, the red heating indicator is extinguished, and the heat preservation condition is transferred. After power off, the water temperature drops gradually. When it drops to the set temperature, the thermostat contact moves to close, the power is switched on, the red heating indicator lights up, and the electric heat pipe heats up again. According to the above heating method, the water cooler can control the water temperature between 85-95 ° C. As a water cooler heating body manufacturer, today Xiaobian will come to talk to you about the heating principle of various water dispensers.

In addition, the principle of the warm water dispenser is to press the heating switch, and the power supply provides power for the "heat preservation" indicator light. A heating circuit is formed to make the electric heat pipe heat up; The other provides voltage to the "heating" indicator for heating. 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. The water temperature drops to the set temperature, the thermostat contact is connected to the power supply circuit, the electric heat pipe is heated again, so that the water temperature is kept between 85-95℃.

There is also the principle of the cold and hot water dispenser. The cold and hot water dispenser is provided by the water tank at normal temperature, and the water is entered into two ways: one way into the cold bladder container, and the cold water is cooled; The other goes into a hot tank and is heated to produce hot water. After the refrigeration switch is pressed, the AC voltage is reduced by the power transformer, the rectifier diode is used for full wave rectification and the capacitor filter, and the DC voltage is output for the semiconductor refrigeration component cooling and the fan exhaust. At the same time, the refrigeration indicator light is lit. Since the straight-cooled hot and cold water dispenser does not have automatic temperature control, the cooling indicator light is always on after starting. Press the heating switch, the heating indicator lights up, the electric heat pipe heats up, the water temperature in the hot tank rises, reaches the set temperature, the thermostat contact is disconnected, the heating power supply is automatically cut off, the heating indicator is off, the electric heat pipe stops heating. The water temperature drops to the set temperature, the thermostat contact is closed, the heating power is automatically switched on, the heating indicator is on, and the electric heat pipe is heated. Then repeat the above process to keep the water temperature at a constant temperature between 85-95 ° C.
