Water-saving clean drinking machine and concentrated water control method thereof

Abstract

The invention discloses a water-saving clean drinking machine and a concentrated water control method thereof. The water-saving clean drinking machine comprises a water making system and a control system. The water making system comprises a raw water tank, a water pump, a front filter element system and a reverse osmosis membrane filter element which are communicated in sequence. A clean water outlet of the reverse osmosis membrane filter element is communicated with the clean water tank, and a concentrated water outlet of the reverse osmosis membrane filter element is communicated with a concentrated water discharging system. The concentrated water discharging system comprises a wastewater ratio solenoid valve, a water discharging valve and a throttling valve. The wastewater ratio solenoid valve and the throttling valve are communicated with the concentrated water outlet, the water discharging valve is communicated with the wastewater ratio solenoid valve, and the throttling valve is communicated with a water path in front of the water pump. The ratio of the flow of concentrated water generated by the reverse osmosis membrane filter element to the flow of clean water is lager than 2, and the total amount of concentrated water generated by the reverse osmosis membrane filter element is proportionally distributed. According to the water-saving clean drinking machine and the concentrated water control method thereof, the distribution proportion of concentrated water produced by a reverse osmosis system can be regulated and controlled, it is avoided that overlarge working pressure is increased for the system, the situations of scaling blockage and the like of a reverse osmosis membrane and a filter system are relieved, and the service life of the reverse osmosis membrane is guaranteed while concentrated water is recycled.

Description

technical field [0001] The invention relates to the technical field of drinking water preparation, in particular to a water-saving drinking water purification machine and a concentrated water control method thereof. Background technique [0002] With the advancement of products and the development of society, drinking water purifiers integrating water purification and drinking water functions are becoming more and more popular, especially RO drinking water purifiers, which have achieved rapid development, but the reverse osmosis system The amount of waste water in the configuration is large, resulting in waste of water resources; some products have adopted some water-saving measures, such as concentrated water backflow, etc., but there are problems such as high working pressure of the system, easy blockage of the membrane or water system, etc., which affect the service life of the membrane. Contents of the invention [0003] The present invention aims to solve the problems...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims to solve the problems of waste of water resources in current water purification machines, lack of control of concentrated water backflow, high working pressure of the system, easy blockage of reverse osmosis membrane or waterway system, etc., and provides an adjustable and controllable diversion of concentrated water generated by the reverse osmosis system Ratio, do not add excessive working pressure to the system, reduce fouling and clogging of reverse osmosis membrane and filtration system, and ensure the service life of reverse osmosis membrane while realizing concentrated water reuse
