METHOD FOR BLOCKING RAW WATER, CONCENTRATED WATER OR WATER PURIFICATION OF HOME REVERSE OSMOSIS WATER PURIFIER

摘要

PURPOSE: A method for blocking raw water, concentrated water or water purification of a home reverse osmosis water purifier is provided by using an automatic opening/closing valve without using a pressure pump or applying electric power. CONSTITUTION: A water purification(10) line purified by a reverse osmosis filter(3) is connected to a water purification connecting part(5-1) of an automatic opening/closing valve(5). Concentrated water(9) passed through the reverse osmosis filter(3) is connected to a concentrated water connecting part(5-2). When a water level of water purification storing tank(8) is full, a water level control valve(7) is closed. Thereby, the pressure accumulated by raw water(11) pressure in the water purification connecting part(5-1) of the automatic opening/closing valve intercepts the flow of the raw water(11) or concentrated water(9). The time for blocking the raw water or the concentrated water from the point of closing the water level control valve of the water purification storing tank is dependent on the raw water pressure and the length from a water purification connecting part outlet of the automatic opening/closing valve to an entrance of the water level control valve of the water purification storing tank.
