PURPOSE: A self-cooling type hot/cold water dispenser that has a built-in distillation device is provided, in which for condensation water vapor generated in a heater is introduced into a spiral pipeline arranged to pass through cold water storage tank. CONSTITUTION: The water dispenser comprises the parts of a boiler body(3) installed with spaced apart from a cold water tank(5); water valves(3',5A) installed to connect the boiler body to the cold water tank; drainage hoses(5B',3C) connected to water drainage valves(3'',5B) to discharge drainage into a drainage basin(20); a water supply pipe(8A) connecting water supply valve(5') formed at one lower side of the cold water tank(5) with a control valve(8') of water supplied; a heater(4) into which water transferred through the cold water tank is supplied to vaporize liquid water; a spiral pipeline(3A) at one end of which a discharge valve(3D) is formed, and at the other end of which a control valve(3B) is installed so that water vapor is condensed as passing through the cold water tank(5). |
