That is, the hot water boiler converts electric energy into heat energy by using a heater with strong thermal conductivity in a high-power state, and the heat energy transfers the heat to the water, and the water is heated quickly by using strong heat. When the water tank is full, the cold water tank and the open water tank are balanced. When heating, the water temperature in the boiling water tank boils to the boiling point, and the boiling water boils to the boiling water tank. At the same time, the water level of the boiling water tank is lowered, and the cold water tank is automatically replenished. This circulation ensures the continuous supply of one-time boiled fresh water without mixing raw water, heat preservation and power consumption, saving energy by 60% compared with traditional water boilers.

Traditional drinking fountains are repeatedly heated. Due to the long boiling time, the content of heavy metals such as calcium and magnesium and non-volatile substances such as nitrite in water is high. Traditional drinking fountains consume a lot of electricity. During the heating process of the hot container of the water dispenser, hot water will flow back to the water storage bucket, which will increase the temperature of the water storage bucket and lead to unnecessary power consumption during refrigeration.

Matters needing attention in using water dispenser

1. The sockets and power cords used in drinking fountains should meet the specified requirements, and pay attention to regular inspection. If any damage is found, it should be repaired and replaced in time to prevent accidents.

2. The drinking fountain should be placed in a well-ventilated place, and there should be no inflammable, explosive, heat source, fire source, corrosive gas or dusty places around it.

3. Unplug the power plug or turn off the power switch of the water dispenser when no one is around, which is safe and saves electricity. When it is found that the bottled water on the drinking machine is running out, unplug the power plug in time and notify the water station to deliver water to avoid dry burning.
