After the warm water is connected to the warm water tank for storage, the water temperature sensing unit separately heats the hot water tank and the warm water tank; since the water storage tank needs to maintain the constant temperature, the water temperature sensing unit needs to be started frequently, so that The water consumption of the water dispenser is increased, and the internal setting of the hot water tank and the warm water tank is required to form a bulky space and occupying space.

Recently, in order to improve the lack of power consumption caused by the constant temperature of the water storage tank, the water dispenser industry has a water dispenser that is heated and boiled in an instant. The operation mode is that the raw water is pumped out of the water storage bucket from a pump and heated by a moment of heating. The device is boiled into hot water and then discharged from a water outlet; however, the water dispenser can only supply 100 °C hot water, and the user needs to add cold water to cool down before drinking, so this mode is very inconvenient. Some manufacturers also add a cooling unit that cools the hot water inside the instant boiling water dispenser. This method allows the user to conveniently drink warm water, but the cooling unit applies electric energy for cooling. From the perspective of energy use, the drinking machine first consumes electric energy to boil the raw water, and then consumes electric energy to cool the hot water. It seems that there is a double waste of energy.
