STERILIZING DEVICE OF LOW TEMPERATURE WATER TREATING MACHINE AND ITS CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide a sterilizing device of a low temp. water treating machine capable of improving a sterilizing power while preventing a generation of ozone (O3 ) by driving an ultraviolet lamp as for every prescribed time at high water level and middle water level and to provide its control method. SOLUTION: This device is composed of a water level sensing means 102 sensing the water level of a water treating tank, a control means 110 controlling a driving time of the ultraviolet lamp by counting the time by a water level sensing signal sensed with the water level sensing means 102 and a lamp driving means 126 driving the ultraviolet lamp so that the clear water may be sterilized by irradiating the clear water with UV rays.
