Waste water ratio solenoid valve, solenoid valve discharge.
After the t1 time, water purification system is run under high-recovery state, waste water ratio solenoid valve power-off, solenoid valve power-off.From
After concentrated water processing unit processes, a part of concentrated water is discharged the concentrated water of RO film surface discharge by waste water ratio；Another part is dense
Water is back between inlet water solenoid valve and stabilized pressure pump by waste water ratio solenoid valve, check valve.
Water purification system enters back into low rate of recovery operation after the t2 time, so recycles.
It is also identical with embodiment one, it can be achieved that two kinds of backwashing manners of circulation flushing and pulse lavage when water purification system is rinsed,
In this not go into detail.
Embodiment six
Fig. 6 shows the structure of the embodiment six of the water purification system of the utility model, the water purification system and reality of embodiment six
The difference for applying example five is coupling part.In embodiment six, coupling part includes the first pipeline 45 and second being arranged in parallel
Pipeline 46, the first pipeline 45 are equipped with waste water ratio 74, and the second pipeline 46 is equipped with solenoid valve 75, that is, use waste water ratio 74 and solenoid valve
The waste water ratio solenoid valve 57 of 75 combination alternative embodiment five forms the structure of the water purification system of embodiment six.
The utility model additionally provides a kind of water purifier, and water purifier includes: body and the water purification system that is arranged on body,
Water purification system is above-mentioned water purification system.
It can be seen from the above description that the above embodiments of the utility model achieve the following technical effects:
1, front filter element and postposition filter core are combined into a filter core, and integrated filter core reduces filter core quantity, reduction user changes
Core frequency reduces leak risk, simplifies water purification system with core cost, reduction waterway connector quantity is changed, and realizes that water purifier is small in size
Type.
2, water purification system has the function of water purification and out two kinds of pure water out, meets user's use demands.
3, the reflux of waste water discontinuous and discontinuous discharge, reduce discharge of wastewater, wash away RO film in time, realize pressure before RO film
It is relatively stable, achieve the effect that water-saving, protection RO film.
4, it realizes that cycle pulse rinses, can more effectively slow down RO film surface concentration polarization than conventional flush mode, extend RO
Membrane lifetime.
5, concentrated water processing unit can be further processed the condensed water being discharged from RO film surface, slow down RO film surface concentration polarization
Change, preferably protection RO film, extends RO membrane lifetime.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or
It changes among the protection scope created still in the utility model.
