How to use water-saving ultrapure water machine

Abstract

The invention discloses a method for using a water-saving ultra-pure water machine. The pure water flushing pipe is connected to the water inlet pipe through the water inlet pipe tee, the concentrated water return pipe is connected to the concentrated water inlet pipe tee through the concentrated water inlet pipe tee, and the concentrated water inlet pipe tee is connected to the water inlet pipe. The water pipes are connected, so that both concentrated water and purified water can flow back and re-enter the primary filter element group, reducing the TDS value of raw water and restoring the TDS value of raw water, which can effectively save water; when pure water with higher purity is needed, use concentrated water first After a few minutes, turn on the pure water outlet switch, so that the pure water quality will be more pure and fresh. Pure water control four-way valve and concentrated water control four-way valve can ensure timely shutdown. Therefore, the present invention can make the pure water quality more pure and fresh, effectively prolong the service life of the RO membrane, effectively save water, and is convenient and flexible to use.

Description

technical field [0001] The invention relates to a household instant pure water machine without a pressure water storage tank and a water-saving and ultra-pure use scheme. Background technique [0002] At present, the domestic pure water machine on the market has a high TDS value of pure water due to the limited desalination rate of the RO membrane when the influent water quality is high when the TDS value is high, so it will affect the purity of the water; when the TDS value is low, according to the specified value Draining concentrated water causes water waste. The existing concentrated water reflux water inlet method requires a large amount of flushing water to restore the inlet water value (about 1:7, 7 parts of mixed water need to be discharged to restore the original inlet water quality after 1 part of concentrated water is discharged), and the actual use The small amount of mixed water used will cause the TDS value of the RO membrane to be high, resulting in low purit...

The existing concentrated water reflux water inlet method requires a large amount of flushing water to restore the inlet water value (about 1:7, 7 parts of mixed water need to be discharged to restore the original inlet water quality after 1 part of concentrated water is discharged), and the actual use A small amount of medium mixed water will cause the TDS value of the RO membrane to be high, resulting in low purity of the pure water and reducing the service life of the RO membrane.
