Energy-saving type water dispenser capable of automatically boiling water by electric heating or automatically cooling boiled water in short time

The invention discloses an energy-saving type water dispenser capable of automatically boiling water by electric heating or automatically cooling boiled water in a short time, relating to an energy-saving type water dispenser with double water heating buckets and with the functions of automatically boiling water by electric heating or automatically cooling. The energy-saving type water dispenser comprises a water heating bucket 8 and a water heating bucket 9, wherein an water level automatic control buoy, a cooling circulation pipe and a cooling water electromagnetic valve are assembled in each of the two water heating bucket; each cooling pipe is connected with a tap water pipe through a pipeline arranged on the water dispenser. When the water heating bucket 8 is used for heating water, the water level in the water heating bucket 8 is high water level, and the water level in the water heating bucket 9 is the lowest water level; when the water in the water heating bucket 8 is boiled, a temperature control switch arranged on the water heating bucket 8 actuates to automatically control an electric heating element to power off and automatically controls an electromagnetic valve D4 to open at the same time, and cooling water flows into the water heating bucket 9 through the cooling pipe arranged in the water heating bucket 8; when the water in the water heating bucket 9 flows to the highest water level, the water level buoy in the water heating bucket 9 controls the electromagnetic valve D4 to power off, and most heat in the boiled water in the water heating bucket 8 is brought to the water in the water heating bucket 9 in the cooling process of boiled water in the water heating bucket 8, and thus energy is saved.
