Title:
WATER PURIFIER
Document Type and Number:
WIPO Patent Application WO/2022/270819
Kind Code:
A1
Abstract:
A water purifier comprises: an RO filter comprising a non-filtering unit to which raw water is introduced, a filtering unit for discharging purified water, and a reverse osmosis membrane for delimiting the non-filtering unit and the filtering unit and for purifying the raw water into the purified water; a raw water storage unit; a purified water storage unit; a water storage tank comprising a separator membrane made of a non-permeable material so as to independently delimit the raw water storage unit and the purified water storage unit and to have elasticity, the water storage tank being configured such that, when the raw water storage unit expands, the purified water storage unit contracts, and when the purified water storage unit expands, the raw water storage unit contracts; a flow channel for providing a passage along which the raw water and the purified water flow; a valve unit comprising multiple valve modules selectively opened/closed to adjust the flow in the flow channel; and a control device for controlling the opening/closing of the multiple valve modules on the basis of multiple flow modes. The multiple valve modules are opened/closed such that, in a purified water storage mode, the raw water is introduced into the non-filtering unit, and the purified water discharged from the filtering unit is introduced into the purified water storage unit.
