ABSTRACT:
A water purifier includes filters for purifying tap water, a storage tank for storing the purified water, and hot and cold water tanks for respectively heating and cooling water received from the storage tank. Water is dispensed from the hot and cold water tanks. An ultraviolet lamp is provided for sterilizing water in the storage tank. A controller controls a valve for supplying tap water to the filters. The controller closes the valve when water in the storage tank reaches a first reference level and opens the valve when the water level descends to a second reference level. The controller keeps the lamp deactivated while the valve is open, and activates the lamp at periodic intervals during a time when the water level remains above a third reference level.
