58 real-time detection pure water TDS of probe reminds user's water purifier operating status and water safety situation.TDS probe 58 has temperature-sensitive
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:
If user uses water purification: raw water is flowed out after the filtering of the front filter element of composite filter element by flowmeter, outflow
Water purification can directly be connect with tap, for users to use.Wherein the flowmeter of water pipeline can be used for marking water purification amount.
If user use pure water: raw water by composite filter element front filter element processing filtering after, by inlet water solenoid valve 51,
Stabilized pressure pump enters reverse osmosis filter core, and the moisture after reverse osmosis filter core advanced treating is pure water and concentrated water, wherein pure water can divide
There are two flow paths, pressure pot a flow path: is entered by check valve 53 and high-voltage switch gear；Another flow path: pass through check valve
It into after the postposition filter core processing of composite filter element, is flowed out by flowmeter, TDS probe with temperature sensing package, the pure water of outflow can be with
It is directly connected to tap for users to use.Wherein the water outlet in pressure pot directly can also enter composite filter element by high-voltage switch gear
The processing of postposition filter core after, flowed out by flowmeter, TDS probe with temperature sensing package, connect with tap it is direct for users to use.
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, in the power-off of waste water ratio solenoid valve 57, the second concentrated water pipeline 42
Solenoid valves: a part of concentrated water is discharged by waste water ratio；Another part concentrated water passes through waste water ratio solenoid valve 57, the second concentrated water pipe
Solenoid valve discharge on road 42.
After the t1 time, water purification system is run under high-recovery state, the power-off of waste water ratio solenoid valve 57, the second concentrated water pipeline
Solenoid valve power-off on 42: a part of concentrated water is discharged by waste water ratio；Another part concentrated water passes through waste water ratio solenoid valve, check valve
It is back to water tank.
After the condensed water being back in water tank enters water tank, if the water level in water tank is lower than low water level, water storage
Solenoid valves on pipeline, the water filtered from the front filter element of composite filter element enter water tank；If water level is higher than high water level, storage
Solenoid valve power-off in water lines.In water tank, the condensed water flowed out from RO film surface can be diluted in water tank, can
Effectively to slow down the concentration polarization of RO film surface.
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 rinse modes 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.
