Abstract

PROBLEM TO BE SOLVED: To perform sterilization with ultraviolet rays by a method wherein a flange having a quartz window installed therein is arranged at a cold-water tank of a drinking water dispenser, ultraviolet rays are radiated from outside the cold-water tank through the quartz window and drinking water in the cold water tank is agitated. SOLUTION: Drinking water stored in a cold-water tank 5 is sterilized with ultraviolet rays radiated from an ultraviolet ray lamp through a quartz window of a flange 9. In addition, in concurrent with sterilization by ultraviolet rays, a rragnet 12 and a sterling device acting as an agitating mechanism agitate the drinking water within the cold-water tank 5. With such an arrangement as above, entire drinking water within the cold-water tank 5 can be sterilized. Further, in the case of normal sterilization with ultraviolet rays, water temperature is increased by heat generated by the ultraviolet ray lamp 10. However, in accordance with this constitution, since the drinking water within the cold- water tank 5 is agitated, heat generated by the ultraviolet ray lamp 10 can be dispersed over the entire drinking water and increasing in water temperature can be restricted as minimum as possible.

The drinking water stored in the cold water tank 5 is set around the cold water tank 5 and is cooled to about 4 to 10 ° C. by a cooling pipe 8 connected to a refrigerator. The drinking water stored in the cold water tank 5 is sterilized by the ultraviolet light emitted from the ultraviolet lamp 10 through the quartz window of the flange 9 provided with the quartz window by the ultraviolet sterilizer. The ultraviolet lamp 10 is shielded by a lamp cover 11, so that ultraviolet rays do not leak outside.
Simultaneously with the ultraviolet sterilization, the drinking water in the cold water tank 5 is stirred by using the magnet 12 and the stirrer 13 as a stirring mechanism, whereby the whole drinking water in the cold water tank 5 is sterilized. In normal UV sterilization, the water temperature rises due to the heat generated by the UV lamp, but here the drinking water in the cold water tank is stirred, so the heat from the lamp is dispersed throughout the drinking water and the rise in water temperature is minimized. Can be suppressed. When using cold water, the cold water extraction valve 14
Is supplied as cold water outside the dispenser.
The cold water tank 5 is provided with a drain valve 16.
