In other embodiments, the water level detecting member 430 may also be a water level sensor disposed in the water storage device 200, and the water level sensor may directly detect the water level in the water storage device 200, and it should be noted that, when the water level detecting member 430 is a water level sensor, the pressure switch 432 may also be disposed at the same time, and at this time, the pressure switch 432 may detect the opening and closing condition of the faucet. It should be noted that, instead of providing the water level detection member 430, the controller 800 may determine the water level in the water storage device 200 by timing, because the water storage efficiency of the water storage device 200 is generally fixed, and the controller 800 may directly calculate and determine the water level in the water storage device 200 from the beginning of the water storage timing.
The working principle and the process of the water purification system 10 are as follows:
when a user needs to take water to open a faucet, the controller 800 controls the water purification system 10 to execute a water production process, specifically, the controller 800 controls the first valve 610 and the second valve 710 to be closed, controls the third valve 330, the fifth valve 420, the sixth valve 510 and the seventh valve 520 to be opened, and tap water sequentially flows through the three-way switch 310, the pre-filter 320, the third valve 330 and the first booster pump 340 and then enters the reverse osmosis filter element 100 through the raw water inlet 110. After being filtered by the reverse osmosis filter element 100, part of the water is changed into pure water, and part of the water is changed into concentrated water.
Specifically, referring to fig. 3, the reverse osmosis filter element 100 may be divided into A, B and C regions, wherein the raw water region a is directly communicated with the raw water inlet 110 for receiving tap water, the concentrated water region B is communicated with the concentrated water outlet 130 and is provided with a plurality of reverse osmosis membranes for receiving concentrated water formed by the tap water passing through the plurality of reverse osmosis membranes, and the pure water region C is communicated with the pure water outlet 120 for receiving pure water formed by the tap water passing through the plurality of reverse osmosis membranes. Tap water entering from the raw water inlet 110 firstly enters the raw water area A and then enters the concentrated water area B, under the filtering action of the multilayer reverse osmosis membrane of the concentrated water area B, a part of tap water enters the pure water area C and is changed into pure water, and the rest part of tap water is left in the concentrated water area B to form concentrated water.
The pure water flows out from the pure water outlet 120, and then sequentially flows through the check valve 410, the fifth valve 420, and the pressure switch 432 to reach the faucet for the user to take. The concentrated water flows out from the concentrated water outlet 130, passes through the sixth valve 510 and the seventh valve 520 in sequence, and is discharged.
After the user finishes taking water, the water faucet is closed, the controller 800 controls the water purification system 10 to start executing the water storage process, the fourth valve 220 is opened, the water production process continues to be executed, the water pressure in the pure water pipeline 400 starts to rise, the pure water flowing out of the pure water outlet 120 starts to enter the water storage device 200 through the water storage pipeline 210 for storage, the water level in the water storage device 200 gradually increases, and the concentrated water is still discharged through the concentrated water pipeline 500. When the water level in the water storage device 200 reaches a certain height, the water pressure in the pure water line 400 further rises.
When the water pressure in the pure water pipeline 400 exceeds the design pressure of the pressure switch 432, the pressure switch 432 sends an electrical signal to the controller 800, and the controller 800 controls the water purification system 10 to start the flushing process after receiving the electrical signal. Specifically, the controller 800 controls the third valve 330, the fifth valve 420, the sixth valve 510 and the first booster pump 340 to be closed, and controls the first valve 610, the second valve 710, the fourth valve 220 and the second booster pump 620 to be opened, so that the pure water stored in the water storage device 200 flows out, sequentially flows through the pure water pipeline 400, the flushing pipeline 600 and the concentrated water pipeline 500, and then enters the concentrated water region B of the reverse osmosis filter element 100 through the concentrated water outlet 130, the original concentrated water in the concentrated water region B enters the raw water region a and flows out from the raw water inlet 110 under the driving of the pure water, and then sequentially flows through the raw water pipeline 300 and the drainage pipeline 700 and is discharged, that is, the concentrated water in the concentrated water region B is replaced by the pure water flowing in from the concentrated water outlet 130, and the generated wastewater flows out from the inlet 110.
The concentrated water region B of the reverse osmosis filter element 100 is directly flushed through the concentrated water outlet 130, so that the concentrated water in the concentrated water region B can be directly replaced, the replacement path is effectively shortened, the amount of pure water consumed by replacement is relatively small, and compared with the prior art in which pure water is injected from the raw water inlet 110 for replacement, water resources can be effectively saved.
When the user needs to take water again to turn on the faucet, the water pressure in the pure water pipeline 400 will be reduced, when the water pressure is reduced to the design pressure of the pressure switch 432, the pressure switch 432 will send an electric signal to the controller 800, and after the controller 800 receives the electric signal, the water purification system 10 is controlled to execute the water production process again.
To sum up, this water purification system 10 adds the first valve 610 that washes pipeline 600 and be used for the break-make to wash pipeline 600 between water storage device 200 and reverse osmosis filter core 100's dense water export 130, make the pure water in the water storage device 200 under the condition that first valve 610 was opened, can follow reverse osmosis filter core 100's dense water export 130 and get into, thereby it replaces the dense water wherein to wash reverse osmosis filter core 100, thereby reduce or even eliminate the concentration difference between the dense water in the reverse osmosis filter core 100 and the pure water, just can not take place the osmotic effect after water purification system 10 stops, TDS in the pure water can not rise because of the TDS infiltration in the dense water, thereby effectively improve the higher problem of TDS of the first cup of pure water after water purification system 10 restarts, improve user experience. Meanwhile, as the concentrated water in the reverse osmosis filter element 100 is directly replaced, the replacement path is short, the consumption of pure water is low, and the water resource can be effectively saved.
The actual water saving effect can be referred to the following table:
it can be seen from the above table that, under the condition that the TDS of the tap water is the same, the TDS of the first cup of pure water after the water purification system 10 without the flushing process is restarted is the highest in the related art, and the TDS of the first cup of pure water after the water purification system 10 with the flushing process is restarted is the same in the related art, and the TDS of the first cup of pure water after the water purification system 10 provided by this embodiment is the lowest. The water purification system 10 provided with the flushing flow path in the related art not only has higher TDS of the first cup of pure water than the water purification system 10 provided in this embodiment, but also consumes a higher amount of pure water than the water purification system 10 provided in this embodiment. Therefore, the water purification system 10 provided by the embodiment can effectively improve the TDS of the first cup of pure water after the water purification system 10 is restarted, and the water consumption of the flushing process is less, so that the waste of water resources can be effectively avoided.

The third embodiment:
referring to fig. 5, a third embodiment provides a water purification system 10, which has substantially the same overall structure, operation principle and technical effect as the first embodiment, except that there are some differences in the arrangement of the drainage pipeline 700.
Specifically, in this embodiment, the reverse osmosis filter element 100 further has a drain port 140, the drain port 140 communicates with the raw water region a of the reverse osmosis filter element 100, the drain port 140 communicates with a drain line 700, and a second valve 710 is disposed on the drain line 700. When the second valve 710 is opened, the wastewater generated by flushing the reverse osmosis cartridge 100 can be discharged through the drain port 140 into the drain line 700.
That is, the drain line 700 is not connected to the raw water line 300, but directly connected to the raw water region a of the reverse osmosis filter cartridge 100, and the waste water generated after the concentrated water region B is washed can directly enter the drain line 700 through the drain opening 140 to be discharged, without flowing through the part of the raw water line 300, so that the complexity of the raw water line 300 can be simplified, and the flow path of the concentrated water during discharging can be shortened.
