Water-saving water purifier

Abstract

The invention discloses a water-saving water purifier. A concentrated water tube is leaded out of a wastewater tube through a concentrated water triple valve and is connected with an adjustable wastewater proportioner, so the wastewater discharge amount can be selected according to the quality of raw water, no discharge or less discharge is selected if the TDS value of the raw water is small, more discharge or complete discharge is selected if the TDS value of the raw water is high, more wastewater discharge is selected if the application amount of purified water is less (circulating water dilution is less), and less wastewater discharge is selected if the application amount of the purified water is large, so water saving and RO membrane protection effects are reached. Delivery tubes connected with two ends of a water inlet control valve on a water outlet tube of a front-membrane filter assembly control the flow-out of the purified water through the opening and closing of a four-side valve in order to form an independent water way, and the water-saving water purifier has the advantages of no starting of the circuit of the water purifier during purified water dilution and use, convenience for energy saving, and simple structure.

Description

technical field [0001] The invention relates to a water-saving pure water machine, in particular to a circulating water-saving pure water machine with reciprocating circulation of concentrated water and dilution of purified water. Background technique [0002] The waste water circulation type water-saving pure water machine currently on the market cannot respond to changes in raw water quality. When the raw water quality TDS value is high, it is easy to cause RO membrane clogging, and when the water is used for purification, most of the corresponding parts of the pure water machine do not start. Energy saving and complex structure. Contents of the invention [0003] The purpose of the present invention is to provide a water-saving pure water machine which can adjust the amount of waste water according to the change of raw water quality, has a simple structure and is easy to use. [0004] In order to achieve the above object, in the water-saving pure water machine of the p...
