Dimension), activated carbon or ultrafiltration membrane etc.), and core processing unit (reverse osmosis membrane, ultrafiltration membrane etc.) composition, water purifier product it is automatic
Control generally comprises automatic water processed, auto-flushing, water shortage alarm and filter element life prompting etc..Wherein, rational auto-flushing side
Formula and washing time can be effectively ensured and extend the service life of reverse osmosis membrane, and then ensure the pure of water purifier product water outlet
Water quality.
Common flushing control mode is rinsed after water processed to power on flushings currently on the market, timing flushing, during flushing
Between relatively single curing.Although such backwashing manner can achieve the purpose that RO (reverse osmosis) film flushing, during different water processed
Between section, using identical washing time, for the reverse osmosis water purifier of big flow, this is a kind of invisible wave to water resource
Take.
The content of the invention
The technical problem to be solved in the present invention is because of auto-flushing time single curing in water purifier control system, and cause
The phenomenon of water resource waste.The present invention provides a kind of control method of the adjust automatically washing time of reverse osmosis water purifier.
The present invention is to solve above-mentioned technical problem by following technical proposals：
The present invention provides a kind of control method of the adjust automatically washing time of reverse osmosis water purifier, its feature is,
Comprise the following steps：
S1, set reverse osmosis water purifier the water time processed and washing time correspondence；
S2, detection reverse osmosis water purifier to be rinsed the water time processed, and inquire about corresponding with the water time processed detected
Washing time, the washing time inquired is adjusted to by the washing time of the reverse osmosis water purifier to be rinsed；
S3, according to the washing time after adjustment the reverse osmosis water purifier to be rinsed is rinsed, judge before rinsing
The current operating conditions of the reverse osmosis water purifier to be rinsed are also non-water states processed for water state processed；
If water state processed, then open scouring electromagnetic valve and be rinsed, and scouring electromagnetic valve is closed at the end of flushing；
If non-water state processed, then scouring electromagnetic valve is first opened, and open after first time period booster pump and into water power
Magnet valve is rinsed, and at the end of flushing, first closes booster pump and entering water electromagnetic valve, and close and rinse after second time period
Solenoid valve.
It is preferred that step S1Further include before：
S01, judge that the reverse osmosis water purifier is in running order or holding state, if in running order, perform
Step S1If being in holding state, step S is performed11；
S11, detection reverse osmosis water purifier to be rinsed stand-by time whether exceed preset time threshold, if so, then by institute
The washing time for stating reverse osmosis water purifier to be rinsed was arranged to for the 3rd period, then performed step S3, if it is not, then continuing to treat
Machine.
It is preferred that the 3rd period is 20 seconds.
It is preferred that the preset time threshold is 3 days.
It is preferred that the first time period and the second time period are 1 second.
It is preferred that step S1Described in water time processed and the correspondence of the washing time include：
If the water time processed is less than 1 minute, the washing time is 3 seconds；
If the water time processed was greater than or equal to 1 minute and less than 5 minute, the washing time is 5 seconds；
If the water time processed was greater than or equal to 5 minutes and less than 10 minute, the washing time is 8 seconds；
If the water time processed is greater than or equal to 10 minutes, the washing time is 12 seconds.
The positive effect of the present invention is：The present invention being capable of the difference water period pair based on reverse osmosis water purifier
Different washing times should be set, so as to adjust the washing time of reverse osmosis water purifier and bath dosage so that the present invention
Auto-flushing control more rationally, more targetedly, and then be effectively saved water resource.
Brief description of the drawings
Fig. 1 is the flow chart of the auto-flushing control method of the reverse osmosis water purifier of presently preferred embodiments of the present invention.
Embodiment
The present invention is further illustrated below by the mode of embodiment, but does not therefore limit the present invention to the reality
Apply among a scope.
As shown in Figure 1, the auto-flushing control method of the reverse osmosis water purifier of the present invention comprises the following steps：
Step 100, judge that the reverse osmosis water purifier is in running order or holding state, if in running order,
Step 101 is then performed, if being in holding state, performs step 1011；
Wherein, step 1011 is：Whether the stand-by time for detecting reverse osmosis water purifier to be rinsed exceedes preset time threshold
Value, if so, the washing time of the reverse osmosis water purifier to be rinsed then was arranged to the 3rd period, then performs step
103, if it is not, then continuing standby；
Wherein it is preferred to which the preset time threshold is 3 days, the 3rd period is 20 seconds, i.e., is treated if detected
The reverse osmosis water purifier of flushing is standby more than 3 days, then the washing time of reverse osmosis water purifier to be rinsed is arranged to 20 seconds；
The correspondence of step 101, the water time processed that reverse osmosis water purifier is set and washing time；
In the step 101 of the present invention, pointedly the difference water period correspondence of reverse osmosis water purifier can be set
Put different washing times, it is preferable that in embodiment, above-mentioned correspondence includes：
If the water time processed is less than 1 minute, the washing time is 3 seconds；If the water time processed is greater than or equal to 1
Minute and less than 5 minutes, then the washing time is 5 seconds；If the water time processed is greater than or equal to 5 minutes and less than 10 point
Clock, then the washing time is 8 seconds；If the water time processed is greater than or equal to 10 minutes, the washing time is 12 seconds.
The water time processed of step 102, detection reverse osmosis water purifier to be rinsed, and inquire about the water time pair processed with detecting
The washing time answered, the washing time inquired is adjusted to by the washing time of the reverse osmosis water purifier to be rinsed；
In a step 102, the water time processed of reverse osmosis water purifier can be specifically detected, and according to pair set in step 101
It should be related to, inquire about washing time corresponding with the water time processed detected, and rushing the reverse osmosis water purifier to be rinsed
Wash the washing time that the time is adjusted to inquire；
Step 103, according to the washing time after adjustment be rinsed the reverse osmosis water purifier to be rinsed, before flushing
Judge that the current operating conditions of the reverse osmosis water purifier to be rinsed for water state processed are also non-water states processed；
If water state processed, then open scouring electromagnetic valve and be rinsed, and scouring electromagnetic valve is closed at the end of flushing；
If non-water state processed, then scouring electromagnetic valve is first opened, and open after first time period booster pump and into water power
Magnet valve is rinsed, and at the end of flushing, first closes booster pump and entering water electromagnetic valve, and close and rinse after second time period
Solenoid valve.
Preferably, the first time period and the second time period are 1 second.
Wherein, the reverse osmosis water purifier to be rinsed in water state processed, open by booster pump operating, entering water electromagnetic valve,
Waste water solenoid valve is closed.
The auto-flushing control method of the reverse osmosis water purifier of the present invention is corresponding because being set for the different water periods processed
Washing time, and when reverse osmosis water purifier rinses, related electric component is rationally controlled so that the present invention, which has more, to be directed to
Property and more reasonable.
