WATER PURIFYING DEVICE WITH PHOTOCATALYST STERILIZER FOR STERILIZING AND PURIFYING WATER IN STORAGE TANK CONTAMINATED BY BACTERIA

摘要

PURPOSE: To provide a water purifying device with a photocatalyst sterilizer for discharging the sterilized and purified water by constantly sterilizing and purifying water in storage tank that is contaminated or contaminated with the level of water in the storage tank not being influenced. CONSTITUTION: In a water purifying device with a storage tank for storing purified water before users use the water, the water purification device comprises a photocatalyst sterilizer for sterilizing the water by photocatalyst just before the water stored in the storage tank is discharged to the outside of the water purifying device, the photocatalyst sterilizer comprises a head (41), an outer pipe (42), an inner pipe (43), a photocatalyst coated supporting body (44) and an ultraviolet ray irradiator (45), the head is installed at a cover of the storage tank, wherein the outer pipe, inner pipe and ultraviolet ray irradiator are airtightly fixed to a lower part of the head, the ultraviolet ray irradiator is consisted of an ultraviolet lamp (45a) and a quartz tube for protecting the ultraviolet lamp, a photocatalyst is coated on the surface of the photocatalyst coated supporting body insertingly installed a space between the inner pipe and the quartz tube, the outer pipe is extended toward the bottom surface of the storage tank so that water in the storage tank is flown into the photocatalyst sterilizer irrespective of the level of water, water in a lower part of the storage tank is lifted up along a space between the outer pipe and the inner pipe accordingly so that the water is flows in an input hole (43a) on an upper part of the inner pipe and sterilized as the water passes continuously through the photocatalyst coated supporting body installed between the inner wall of the inner pipe and the outer wall of the quartz tube before the sterilized water is discharged to the outside through a discharge port (43b) on a lower part of the inner pipe.
