As Fig. 3, action timing diagram for each valve in the metrological valve device, when adding the liquid that needs automatically, singlechip chip 20 is controlled the action sequence of metrological valve devices by output driving circuit 27: at first control exhaust-valve 4 actions, with the liquid emptying in the buffering area 5, control 3 actions of additive supply valve then, the liquid that needs add is delivered to buffering area 5, outlet valve 2 actions then, the liquid of buffering area 5 can be sent, but because the pressure of buffering area 5 is too small, the liquid that needs to add is directly sent in the washtub, and water intaking valve 1 action is at this moment sent running water into buffering area 5, because the hydraulic pressure of running water is big, running water passes through water intaking valve 1 successively with the liquid that needs in the buffering area 5 to add, buffering area 5, outlet valve 2 is delivered in the washtub through the water route.
As Fig. 4, be the flow chart of metrological valve device control method, it specifically has following steps:
(10), the beginning, control metrological valve device by the single-chip microcomputer that is arranged on the computer plate by output driving circuit;
(20), the action of exhaust-valve, outlet valve, the action T1 time is with the liquid emptying in the buffering area;
(30), close exhaust-valve, outlet valve T2 time;
(31), carry out determining step, if the time T of closing, is then returned step (30) less than the T2 time; If the time T of closing greater than the T2 time, is then carried out next step;
(40), open additive supply valve, action T3 time;
(50), close the additive supply valve T4 time;
(51), carry out determining step, if the time T of closing, is then returned step (50) less than the T4 time; If the time T of closing greater than the T4 time, is then carried out next step;

In step (20), exhaust-valve, outlet valve action T1 time are generally more than 5 seconds; In step (30), close exhaust-valve, outlet valve T2 time and be no less than 1 second; Closing the additive supply valve T4 time in step (50) is no less than 1 second.
In addition, in the metrological valve device of the present invention, buffering area 5 plays a part certain when carrying out the interpolation measure control of additive, when adding the additive of little metering if desired, volume with buffering area is a measurement unit, only the container that buffering area 5 need be arranged to have fixed volume can be arranged to 1ml or 2ml as required; When adding the additive of big metering if desired, then be what of amount of the measurement unit additive of controlling adding with the flow of additive supply valve.The described flow chart of both control methods and Fig. 4 is roughly the same, and only difference is: in carrying out the interpolation liquor charging process of little metering, if a liquor charging does not reach needed amount, then need whole control process is repeated successively again.
Volume with the buffering area of metering valve is the control method of measurement unit
When the volume of buffering area 5 is 1ml, the precision that the liquor charging amount of washing machine control can reach, required additive is 3ml, then at first finishes the control procedure of a liquor charging.
At first controlling exhaust-valve 4 and outlet valve 2 moves simultaneously, actuation time, T1 was about 7 seconds, with in the buffering area 5 and the buffering area 5 abundant emptying of liquid in the loop of washtub in the same way, turn-offing exhaust-valve 4 and 2 a period of time of outlet valve T2 was 2 seconds, control 3 actions of additive supply valve then, actuation time, T3 was 5 seconds, the liquid that needs add is delivered to buffering area 5 and is full of buffering area, turn-offing additive 3 a period of time of supply valve T4 was 2 seconds, outlet valve action T6 then, because the time of T6 needs long enough, could deliver to the liquid of buffering area 5 in the washtub fully, so needing to select T6 was 12 seconds, the liquid of buffering area can be sent, but because the pressure of buffering area is too small, can't make the liquid that needs to add directly send in the washtub, in outlet valve 2 action T5 water intaking valve 1 action after 2 seconds, running water is sent into buffering area 5, because the hydraulic pressure of running water is greatly between 0.02Mpa-0.78Mpa, running water passes through water intaking valve 1 → buffering area 5 → outlet valve 2 with the liquid that needs in the buffering area 5 to add, deliver in the washtub through the water route, outlet valve 2 and water intaking valve 1 turn-off simultaneously.Finish the liquor charging process one time.
This time liquor charging amount is exactly the cubical content of buffering area 5.
Repeat above-mentioned action 2 times then, just can finish whole liquor charging process.
With additive supply valve 3 flows is the control method of measurement unit
Once finish the process that required additive is 4.5ml, the flow of its selected additive supply valve 3 is 1.5ml/s, the volume of buffering area 5 need not set, the amount of the additive that it need add is relevant with the T3 time of control additive supply valve 3 actions, the T3 here is the additive capacity that added by needs with the ratio calculation acquisition of the flow of additive supply valve 3, only the amount input computer plate of the additive that needs need be added just can obtain the time of T3, also can calculate the time of T3 artificially, T3 is about 3 seconds here.
At first controlling exhaust-valve 4 and outlet valve 2 moves simultaneously, actuation time, T1 was about 8 seconds, with in the buffering area 5 and the buffering area 5 abundant emptying of liquid in the loop of washtub in the same way, turn-off exhaust-valve 4 and 2 a period of time of outlet valve T2, T2 was 2 seconds, control 3 actions of additive supply valve then, actuation time T3, the liquid control dosage that needs add is delivered to buffering area 5, turn-off additive 3 a period of time of supply valve T4, T4 is greatly about about 3 seconds, outlet valve 2 action a period of time T6 then, here the time of T6 needs long enough, deliver to the liquid of buffering area 5 in the washtub fully, T6 is about 15 seconds generally speaking, the liquid of buffering area 5 can be sent, but because the pressure of buffering area 5 is too small, can't make the liquid that needs to add directly send in the washtub, in outlet valve 2 action T5 water intaking valve 1 action after 3 seconds greatly, running water is sent into buffering area 5 because the hydraulic pressure of running water is greatly between 0.02Mpa-0.78Mpa, running water with the liquid that needs in the buffering area 5 to add by water intaking valve 1 → buffering area 5 → outlet valve 2, deliver in the washtub through the water route, water intaking valve 1 and outlet valve 2 turn-off simultaneously.
Finish the liquor charging process one time.This time liquor charging amount is exactly the dosage that needs interpolation.
This example is used in heavy dose of liquor charging process, can disposablely finish whole liquor charging process.
