A kind of lack of water detection method of exempting the anti-penetration water purifier of low-tension switch: comprise the following steps:
Step one, anti-penetration water purifier connect electricity, start;
Step 2, measurement wastewater valve 34a closedown, water intaking valve 31a and topping-up pump 5 detect the voltage at resistance 51 two ends when working;
Step 3, measure that wastewater valve 34a opens, water intaking valve 31a and topping-up pump 5 detect resistance 51 two ends voltage when working;
Step 4, calculation procedure two survey with institute in step 3 the volts lost detecting resistance 51 both end voltage, and are converted into the difference between current under wastewater valve 34a closedown and open mode;
Step 5, the difference between current obtained in step 4 to be compared with standard value, judge to draw whether lack of water or pressure of supply water not enough.
Principle of work:
Overhaul flow chart as shown in Figure 2, after anti-penetration water purifier connects electricity, presses switch key start, again presses the shutdown of switch key anti-penetration water purifier.By the disconnection of high-voltage switch gear 32a, Closed control water purifier water whether anti-penetration water purifier after start: when high-voltage switch gear 32a disconnects, represents that the full and stopping of the water of pressure-pot 4 is made; When high-voltage switch gear 32a closes, water purifier is in water state processed.
During water state processed, water to be clean is from water-in 11 water inlet pipe 31, and the polypropylene melt blown filter 61 then successively in preposition filter core group, granulated active carbon filter core 62 and Carbon rod filter element 63, remove impurity in water and peculiar smell completes prefilter; Stretch into purification by reverse osmosis membrane filter element 2 pairs of water again, thus reach the standard of tap water, it is stand-by that the water after purification is stored into pressure-pot 4 through standpipe 33; Waste water in reverse osmosis membrane filter element 2 is discharged from waste water mouth 21 through waste pipe 34.When user takes tap water, water outlet 12 is opened, and the water in pressure-pot 4 flows into after rising pipe 32 through standpipe 33, flows out from water outlet 12.
Wastewater valve 34a closes or opens will affect the change of electric current, if water intaking valve 31a, topping-up pump 5 work, when wastewater valve 34a closes, the electric current of topping-up pump 5 is Ia; Water intaking valve 31a, topping-up pump 5 work, and when wastewater valve 34a opens, the electric current of topping-up pump 5 is Ib; Detect resistance 51, equal and voltage U=resistance R × electric current I according to electric current on series circuit due to topping-up pump 5 being in series with, the electric current measuring wastewater valve 34a closedown or opened condition detects the voltage at resistance 51 two ends under just can being converted into and measuring two states.
Using the difference between current Ia-Ib under two states as judging criterion, under being namely converted into two states, detect the volts lost at resistance 51 two ends.In the present embodiment, detect resistance 51 be 1R/3W resistance ， as ∣ Ia-Ib ∣ < 0.05A, be exsiccosis, during lack of water, topping-up pump 5 quits work, anti-penetration water purifier shutdown; As Ia-Ib > 0.2A, supply water normal, anti-penetration water purifier normally works.Just effectively lack of water can be judged whether by the volts lost detecting resistance 51 two ends under measurement two states, simple, convenient.
When the accumulative water processed of anti-penetration water purifier is after 8 hours, automatically starts flushing action and reverse osmosis membrane filter element 2 is rinsed, rinse and stop after 30 seconds; Flushing can remove the impurity on reverse osmosis membrane, ensures the depuration quality of reverse osmosis membrane, and extends the work-ing life of reverse osmosis membrane.Flushing action can also force flush knob to start by pressing.
Most preferred embodiment of the present invention is illustrated, and the various change made by those of ordinary skill in the art or remodeling all can not depart from the scope of the present invention.
