Packet will affect reverse osmosis membrane service life and water purifier performance when reminding user's raw water temperature too low or too high, need to protect water purification
Machine.
In the present embodiment, flowmeter 54 is also set up in pure water pipeline, flowmeter 54 is used to mark the postposition of composite filter element
Filter element life, remote water delivery, hold one's breath, high-voltage switch gear frequent start-stop the problems such as.
Certainly, Water quality detector, TDS probe, pure water and net water flux meter can simplify according to demand.
The course of work of the water purification system of the present embodiment is illustrated below:
When water purification system water, if user use water purification: raw water enter composite filter element front filter element filtering after by
Water quality detector is divided into two flow paths, wherein one is water pipeline: can be directly connected to tap by flowmeter
Drinking Water.
If user uses pure water: when user opens tap water, when high-voltage switch gear is lower than preset value, water purification system
Start water processed.Raw water by composite filter element front filter element filtering after, by Water quality detector, inlet water solenoid valve, stabilized pressure pump into
Enter reverse osmosis filter core, the moisture after reverse osmosis filter core advanced treating is pure water and concentrated water.Wherein, pure water can be divided into two streams
One flow path: road enters pressure pot by check valve and high-voltage switch gear；Another flow path: composite filter element is entered by check valve
The processing of postposition filter core after, flowed out by flowmeter, TDS probe with temperature sensing package, the pure water of outflow can be directly connected to the fire hose
Head is for users to use.Wherein the water outlet in pressure pot can also directly be entered at the postposition filter core of composite filter element by high-voltage switch gear
After reason, is flowed out, connect with tap directly for users to use by flowmeter, the TDS probe with temperature sensing package.
When user closes tap, when high-voltage switch gear is higher than preset value, water purification system stops water processed.
When water purification system water, water purification system circular flow between low rate of recovery state and high-recovery state, for example,
Low rate of recovery state runs the t1 time, and high-recovery state runs the t2 time, specific as follows:
When water purification system is run under low rate of recovery state, the power-off of waste water ratio solenoid valve 57, solenoid valves.From RO film table
After concentrated water processing unit processes, a part of concentrated water is discharged the concentrated water of face discharge by waste water ratio；Another part concentrated water is passed through
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 water purification system of the invention, the water purification system and embodiment of embodiment six
Five difference is coupling part.In embodiment six, coupling part includes the first pipeline 45 and the second pipeline being arranged in parallel
46, the first pipeline 45 is equipped with waste water ratio 74, and the second pipeline 46 is equipped with solenoid valve 75, i.e., with waste water ratio 74 and solenoid valve 75
Combine the structure of the water purification system of the formation embodiment six of waste water ratio solenoid valve 57 of alternative embodiment five.
The present invention also provides a kind of water purifier, 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 present invention realized the following chievements:
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 still within the protection scope of the invention.
