Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.
Referring to fig. 1 to 5, a waterway system 100 for a water purifying apparatus according to an embodiment of the present invention is described. The waterway system 100 includes: a water inlet waterway 10, a pure water waterway 20, a pure water return waterway 30, and a wastewater waterway 40.
Specifically, the inlet water path 10 is respectively provided with a pre-filter element 51, an inlet electromagnetic valve 52, a booster pump 53 and a reverse osmosis filter element 54, and tap water sequentially passes through the pre-filter element 51, the inlet electromagnetic valve 52, the booster pump 53 and the reverse osmosis filter element 54.
The pure water path 20 is connected to a pure water outlet of the reverse osmosis filter 54, and the pure water path 20 is provided with a first check valve 55, a high-pressure switch 56 and a post-filter 59. One end of the pure water return water path 30 is connected to the pure water outlet of the reverse osmosis filter 54, the other end of the pure water return water path 30 is connected to the water inlet water path 10 and is located between the booster pump 53 and the water inlet solenoid valve 52, and the pure water return water path 30 is provided with a return solenoid valve 57 and a second check valve 58. The waste water path is connected to the concentrated water outlet of the reverse osmosis cartridge 54, and the waste water path 40 is provided with a flushing solenoid valve 59 a.
That is, the reverse osmosis filter element 54 is communicated with the inlet water path 10, the pure water path 20, the pure water return path 30, and the waste water path 40, respectively. When the pure water channel 20 is drained, the tap water is filtered by the pre-filter 51 and then enters the reverse osmosis filter 54 for filtration, and the filtered pure water flows out of the pure water channel 20, and at the moment, the return solenoid valve 57 of the pure water return channel 30 is in a closed state; in the case that the pure water channel 20 does not discharge water, the second check valve 58 and the return solenoid valve 57 of the pure water return channel 30 are opened, the first check valve 55 of the pure water channel 20 is closed, and pure water does not flow into the first check valve 55 and the subsequent channels thereof, only enters the return solenoid valve 57 and the second check valve 58, enters between the water inlet solenoid valve 52 and the booster pump 53, and at this time, the pure water is mixed with tap water, so that the TDS value of water entering the reverse osmosis filter element 54 is reduced, and the reverse osmosis filter element 54 is flushed; the water after washing is discharged from the concentrated water outlet through the washing solenoid valve 59a, so that the problem that the TDS value of the first cup of water is high when the water purifying device is not used for a period of time is solved.
Because pure water route 20 and pure water backward flow water route 30 divide into two relatively independent ways, two way water route separately-positioned places are the pure water export of reverse osmosis filter core 54, and first check valve 55 is on pure water route 20, and the backward flow is prevented when the pure water backward flow and waste water discharge from causing the system pressure unstability to lead to high-voltage switch 56 uneven pressure, make the problem that the complete machine opens and stops repeatedly.
In other words, the pure water passage 20 and the pure water return passage 30 are used without interfering with each other, and a problem that the high-pressure switch 56 is frequently activated due to fluctuation of the water pressure during the pure water return flushing is avoided.
From this, according to the utility model discloses a waterway system 100 for water purification unit falls into relatively independent pure water route 20 and pure water backward flow water route 30 through the pure water export at reverse osmosis filter core 54 to effectively solved the higher problem of reverse osmosis filter core 54 central zone TDS value, and guaranteed high-voltage switch 56 pressurized relatively stable, avoid appearing the complete machine and open the problem of stopping repeatedly.
To avoid wasting water during the back flush, the flush solenoid valve 59a is not opened and the concentrate flows only through the small hole of the flush solenoid valve 59 a. In addition, whether the back flow flushing process is executed or not can be judged according to the time length of the discontinuous water taking, for example, after the water purifying device closes the drinking water faucet, if water is not taken again within 10min, the control system opens the water inlet electromagnetic valve 52, the booster pump 53 and the back flow electromagnetic valve 57 after 10min, the pure water of the reverse osmosis filter element 54 forms mixed water with the tap water at the water inlet electromagnetic valve 52 before flowing to the booster pump 53 through the pure water back flow water channel 30, the TDS value of the tap water is reduced, after the mixed water discharges the high-concentration tap water in the radial inner end area of the reverse osmosis filter element 54 close to the central pipe area through the flushing electromagnetic valve 59a, the water inlet electromagnetic valve 52, the booster pump 53 and the back flow electromagnetic valve 57, and.
After the water purifying device closes the drinking water faucet, if water taking action is carried out again within 10min, the backflow starting timing time is reset, and timing is started after the last water taking is finished. After the drinking water faucet of the water purifying equipment is closed, if water is not taken for more than or equal to 24 hours, the control system controls the machine to carry out backflow washing, the washing mode is consistent with the 10min washing mode, and the freshness of the water channel in the water purifying equipment is guaranteed.
