a) When the water purifier works for producing water, the water taking switch 2 is opened, the first electromagnetic valve 36 is opened, the second electromagnetic valve 32 is closed, the third electromagnetic valve 34 is closed, tap water flow enters the membrane wire 51 from the water inlet 35, after being filtered by the membrane wire 51, purified water flows out from the purified water outlet 31 after passing through the first water conveying gap 502, and the discharged purified water can be drunk by life.
b) When the water purifier works in the forward flushing mode, the water taking switch 2 is closed, the second electromagnetic valve 32 is closed, the third electromagnetic valve 34 is opened, the first electromagnetic valve 36 is opened, tap water flows from the water inlet 35, flows through the first electromagnetic valve 36 and enters the membrane wire 51, the flushed waste water directly flows into the cavities (namely the second water conveying gap 503) at the bottom of the filter element 5 and the bottom of the barrel body 1, and finally is discharged from the first water outlet 33 through the third electromagnetic valve 34. This process is a forward rinse, which cleans most of the dirt in the membrane wire 51, and if it is desired to thoroughly clean deposited and sticky stubborn dirt in the membrane wire 51, it is also necessary to perform a back rinse.
c) When the water purifier is in back flushing operation, the water taking switch 2 is closed, the second electromagnetic valve 32 is opened, the third electromagnetic valve 34 is opened, the first electromagnetic valve 36 is closed, tap water flow enters from the water inlet 35, flows into the first water delivery gap 502 in the barrel body 1 through the second electromagnetic valve 32, tap water reversely enters into the membrane wire 51 to flush the membrane wire 51 under the action of pressure, and the flushed waste water flows into the cavities (namely the second water delivery gap 503) at the bottom of the filter element 5 and the bottom of the barrel body 1, and finally is discharged from the first water outlet 33 through the third electromagnetic valve 34. During the back flushing process, water flow reversely enters the membrane wire 511 from the outside of the membrane wire 51, and the back flushing process is relatively smooth to the flushing process, so that deposited and adhered stubborn stains in the membrane wire 51 can be better cleaned.
The water producing, forward flushing and back flushing processes of the water purifier can be automatically completed by the cooperative work of the control circuit board and the electromagnetic valve.
