AI Technical Summary

Technical Problem

When existing built-in water purifiers stop producing water, some residual water in the pipes will seep through tiny gaps or pressure differences, forming stagnant water. This leads to a decrease in water quality and may breed microorganisms, affecting water safety.

Method used

The reverse water supply system, including components such as a booster pump, solenoid valve, and check valve, directly discharges the stale water in the RO membrane into the wastewater pipe by controlling the opening and closing of the valve, ensuring that the stale water is discharged immediately when the machine stops producing water, preventing it from entering the pure water area.

Benefits of technology

It effectively reduces the TDS value of the first cup of water, reduces the concentration of harmful substances, prevents the growth of microorganisms, improves water quality safety, reduces water waste, and ensures stable and safe water quality.

Abstract

The utility model provides a kind of embedded pure drinking machine zero waste water system with reverse water supply, it is related to pure drinking machine technical field, including water inlet and booster pump, the input end of the booster pump is connected with composite filter element, the output of the booster pump is connected with water inlet solenoid valve, the output of the water inlet solenoid valve is connected with RO membrane, the side of the RO membrane is connected with combined waste water valve.The utility model discloses when machine 30 minutes do not make water using RO membrane front section pure water directly into waste water pipe 5 seconds, the stale water in RO membrane is discharged, to reduce the TDS value of first cup water, machine in 30 minutes has water machine and does not discharge (TDS at that time is not high).Reduce the concentration of harmful substances, prevent impurities in water from re-dissolving or precipitating, improve the safety of water quality;Reduce the reproduction of microorganisms in the water purifier, reduce the risk of microbial contamination, users do not need to put down stale water before taking water, can obtain high-quality purified water at any time, and the taste of water is stable, reduce the waste of water resources.
