Title:
WATER PURIFIER
Document Type and Number:
WIPO Patent Application WO/2022/265274
Kind Code:
A1
Abstract:
This water purifier comprises: an RO filter including a non-filtration part into which raw water flows, a filtration part for discharging purified water, and a reverse osmosis membrane for partitioning the non-filtration part and the filtration part and filtering the raw water into the purified water; a purified water storage part for storing the purified water; a raw water storage part for storing the raw water; a flow channel providing a passage through which the raw water and the purified water flow; a valve part including one or more valve modules that are selectively opened or closed in order to adjust the flow of the raw water and the purified water in the flow channel; a sterilization module for sterilizing the raw water discharged from the non-filtration part; and a controller for controlling the opening/closing of the valve modules and controlling the sterilization module on the basis of a plurality of flow modes. The plurality of flow modes include a flushing mode in which the reverse osmosis membrane is cleaned using the purified water of the purified water storage part. The controller opens and closes the one or more valve modules so that, in the flushing mode, the purified water discharged from the purified water storage part flows into the non-filtration part and flushing discharge water discharged from the non-filtration part flows toward the raw water storage part, and drives the sterilization module in order to sterilize the flushing discharge water.
