Embodiment 1

[0041] 1. The high-voltage switch 12 and low-voltage switch 4 are turned off, the water full light flashes for 5 seconds, and the magnet RO membrane 8 is filled with concentrated water (refer to Figure 4 ), the waste water valve 9 is opened for 3 seconds, and part of the concentrated water in the cavity of the RO membrane 8 is drained (refer to Figure 5 );

[0042] 2. Close the waste water valve 9, open the water inlet valve 3, the water pump 7 and the control valve 15. Since the one-way valve 11 and the high-pressure switch 12 are closed, the pure water purified by the RO membrane 8 flows back to the water pump 7 to mix with the raw water, reducing the loss of raw water. TDS value, and flows back into the RO membrane 8 under the action of the water pump 7 to flush the RO membrane 8 and reduce the TDS value in the RO membrane. This process lasts for 4 seconds (refer to Figure 6 );

[0043] 3. Close the water inlet valve 3, the water pump 7 and the control valve 15 continu...

[0047] 1. The high-voltage switch 12 and low-voltage switch 4 are turned off, the water full light flashes for 5 seconds, and the magnet RO membrane 8 is filled with concentrated water (refer to Figure 4 ), the waste water valve 9 is opened for 3 seconds, and part of the concentrated water in the cavity of the RO membrane 8 is drained (refer to Figure 5 );

[0048] 2. Close the waste water valve 9, open the water inlet valve 3, the water pump 7 and the control valve 15. Since the one-way valve 11 and the high-pressure switch 12 are closed, the pure water purified by the RO membrane 8 flows back to the water pump 7 to mix with the raw water, reducing the loss of raw water. TDS value, and flows back into the RO membrane 8 under the action of the water pump 7 to flush the RO membrane 8 and reduce the TDS value in the RO membrane.

Abstract

The invention discloses a pure water membrane protection system of a large-flow water purifier. The invention relates to the field of high-flow pure water protective films of water purifiers. Aiming at the problems that an RO membrane in an existing large-flow water purifier is soaked in concentrated water with a high TDS value for a long time, the RO membrane is easy to block, the service life ofthe RO membrane is short, proposed now is the following scheme: the pure water membrane protection system comprises a water inlet, one end of the water inlet is connected with a front filtering assembly, one side of the front filtering assembly is connected with a water inlet valve, a low-pressure switch is arranged between the water inlet valve and the front filtering assembly, the other side ofthe water inlet valve is connected with a water pump, the water pump is connected with the RO membrane, the wastewater drainage pipe of the RO membrane is connected with a wastewater valve, and the other side of the wastewater valve is provided with a wastewater port. The pure water membrane protection system is novel in structure and good in membrane washing and protecting effect, the service life of the RO membrane is effectively prolonged, the replacement cost is reduced, and the problem that the water quality of first cup water is poor is solved.

Description

technical field [0001] The invention relates to the field of pure water protective film for large flow water purifiers, in particular to a pure water protective film system for large flow water purifiers. Background technique [0002] The water purifier pressurizes the tap water through the water pump, and then filters out the impurities, bacteria and heavy metal elements in the tap water through the water purification filter element, which is not conducive to the health of drinking water, so as to achieve the purpose of purifying the water quality, and most of the water purifiers on the market pass RO membrane to achieve water purification. [0003] When the water purifiers with small flow rate on the market are in use, due to the slow water purification effect of the RO membrane, a pressure tank is usually installed inside the water purifier, and the purified pure water is stored in the pressure tank to facilitate water intake. , take it as you go. [0004] When the larg...
