Abstract

A rapid electric heating water dispenser includes a body, a base, an electric heating element located in the body, a hot water drain valve and a hot water outlet. A water pipe and an electric heating tube cling to each other through a casting body. A liquefaction inner tube between the outlet of the aforesaid water pipe and the hot water drain valve. The electric heating tube has a capacity matched with the volume of the water pipe to heat the water passed by to at least 75° C. A water head is located between the water inlet of the liquefaction inner tube and the water circuit connected with it, and the water level of the liquefaction inner tube should be higher than that of the water circuit.

Claims (22)
