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.
