A raw water control valve is installed in the intake control space to control the intake of raw water, and a flow path conversion valve is installed in the purification control space to control the purification of the introduced raw water so that the introduced raw water is discharged via the outlet port when the purification filter is separated from the cap. The purification filter has a supporting protrusion and a pair of pressing parts so that the introduced raw water is purified and discharged by the flow path conversion valve and the raw water control valve being pressed when the purification filter is coupled with the cap. Thereby, the introduced raw water is bypassed without any additional manipulation when separating the purification filter from the cap.
The present design relates to a disinfection unit for a water purifier which uses an ultraviolet lamp to disinfect water being purified and discharged. The present design provides a disinfection unit for a water purifier wherein a corrugated pipe, which covers the entire space between an inlet pipe and an outlet pipe, has a plurality of repeating corrugations and is arranged on the inner wall of a casing to enable water passing through the disinfection unit to be uniformly disinfected by ultraviolet rays and discharged. This disinfection unit enables water introduced through the inlet pipe to form a vortex flow by means of the corrugations in the corrugated pipe so that water is discharged after remaining in the disinfection unit for a sufficient amount of time and is thus fully disinfected, thereby significantly improving disinfection efficiency. Additionally, the shapes of the present pipes are maintained in a stable manner even though they are thinner than conventional high durability steel pipes, and manufacturing costs are thus reduced.
