Specifically, the waterway application principle of the water purification system is as follows:
under the normal water making state, an external tap water source is input from the raw water input end 1, the first control valve 11 is in an open state, the third control valve 52 is in a normally closed arrangement, and under the driving of the supercharging device 5, the water is primarily filtered from the water inlet valve 12 to the preposed filter element assembly to obtain purified water; the obtained purified water passes through the first control valve 11 and the supercharging device 5 to reach the position of the preposed water inlet 61, and is input to the preposed reverse osmosis filter core assembly 6 through the first water inlet flow channel.
The input purified water is filtered by the preposed reverse osmosis filter element assembly 6 to generate first purified water and first wastewater; the second control valve 51 is opened, and the water inflow of the obtained first wastewater to the post reverse osmosis filter element assembly 7 is controlled by applying the second control valve 51; the first wastewater is input to the post reverse osmosis filter element assembly 7 along the second water inlet flow channel for secondary filtration to generate second pure water and second wastewater. The old water control valve 8 is closed, and the obtained first pure water and the obtained second pure water are filtered by the rear filter element assembly along the first pure water flow channel and the second pure water flow channel which are converged and are output from the pure water output end 2.
The user can choose to directly take the obtained purified water, and the obtained purified water is output to the external device through the purified water flow channel and the purified water output end 4.
The wastewater control valve 31 is in an open state, and the resulting second wastewater stream is output to the wastewater output terminal 3 along the wastewater flow path.
On the other hand, if water production is continued for a long time, the first wastewater fed from the rear water inlet 71 has a relatively high concentration, and is not suitable for being directly fed into the rear reverse osmosis filter element assembly 7; the third control valve 52 is opened based on the setting of the flushing flow passage, and the post reverse osmosis filter element assembly 7 is re-flushed by introducing the raw water inputted from the raw water input terminal 1, so as to effectively dilute the inputted first wastewater.
After the water purification system stops working, the TDS values of the corresponding pure water sides of the front reverse osmosis filter core assembly 6 and the rear reverse osmosis filter core assembly 7 are increased along with the time progress until the solute concentrations of the water inlet side and the pure water side reach balance; if the water is directly produced in the following steps, the TDS value of the first cup of water is high.
Therefore, if the user turns on the water-consuming unit of the pure water output 22 by taking water after a predetermined interval of water-taking, the water purification system will be controlled by a predetermined program to start the process of the old water treatment.
In the state of old water treatment, the first control valve 11 is opened, the second control valve 51 is opened, and the supercharging device 5 is started, so that water flow is respectively input into the preposed reverse osmosis filter core assembly 6 and the postposition reverse osmosis filter core assembly 7 along the first water inlet flow channel and the second water inlet flow channel. At this time, the old water control valve 8 is opened, the waste water control valve 31 is opened, and based on the setting of the pressure switch, under the action of the pressure difference, the old water with higher TDS value of the corresponding pure water of the front reverse osmosis filter core assembly 6 and the rear reverse osmosis filter core assembly 7 is output to the waste water output end 3 through the merged first old water flow channel and second old water flow channel to be discharged.
A standing water discharge time is preset, which is preferably 1 to 10 seconds. After the old water discharging time, the old water control valve 8 is closed, and the water purification system is switched to the normal water making state to continue working and application.
The above description is only a preferred embodiment of the present invention, and those skilled in the art may still modify the described embodiment without departing from the implementation principle of the present invention, and the corresponding modifications should also be regarded as the protection scope of the present invention.
