What is the working principle of the water dispenser?

When the water dispenser is used, press the heating switch, and the power supply supplies power for the "heat preservation" indicator light to indicate power on. At the same time, the power supply is divided into two ways: one way forms a heating loop to electrify the electric heating tube to raise the temperature; The other circuit provides voltage for the "heating" indicator lamp, which is used for heating indication. When the water in the hot pot is heated to the set temperature, the contact of the thermostat is disconnected, and the power supply of the heating indicating circuit is cut off.

The "heating" indicator goes out and the electric heating tube stops heating. When the water temperature drops to the set temperature, the contact of the thermostat is connected to the power supply circuit, and the electric heating tube heats up again to keep the water temperature between 85-95℃ repeatedly.

Use and maintenance of extended data drinking machine;

1. Handle the machine carefully. When moving the compressor-cooled water dispenser, please try to keep it upright. If it is tilted, it must not exceed 45 degrees, and it can only work after a period of rest.

2. When using the drinking machine for the first time, first clean the container and pipeline of the drinking machine with clean water, then unscrew the drain valve and tighten the drain valve after draining the residual water in the machine. After adding a large bottle of water, turn on the hot water tap, plug in the power supply after the water flows out, and turn on the heating switch to avoid dry burning and prolong the service life of the machine.

3. If you stop drinking water for a long time, please turn off the switch of the machine and unplug the power plug, then unscrew the drain valve to drain the remaining water in the machine, and then tighten the drain valve (please pay attention to hot water burns when draining).

4. It is best to turn off the power supply when not in use at night, which can save energy and ensure the safety when no one is using it.
