Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
Embodiment 1
In the present embodiment, the unit of each symbol all adopts international standards unit.
As shown in Figure 1, the controlling Method for inflow of a kind of roller washing machine rinse stage provided in the present embodiment, comprises the steps:
S00 step: preset inflow coefficient K in the memory cell of the controller of washing machine p.
Inflow coefficient K pcomputing formula as follows:
K p = L p L z - - - ( 1 )
Wherein, L pfor the water inlet total amount of washing stage, L zfor the water inlet total amount of rinse stage.
That is, the water inlet total amount ratio of the water inlet total amount of washing stage and washing stage is defined as inflow coefficient K p, inflow coefficient K pcan think that does not rely on the quantity of clothing and the absorptive change of clothing and the coefficient changed, only reflect for the proportionate relationship between the water inlet total amount in same a pile clothes washing stage and the water inlet total amount of rinse stage.
S10 step: roller washing machine enters the washing stage, the master in the controller record washing of drum type washing machine stage of roller washing machine inside washes into water duration T z.
Suppose that the flow of inlet water of electromagnetic valve is F a, then the total inflow of washing stage is:
L z＝F a*T z（2）
Preferably, the water intake mode of washing stage is automatic ink-suction mode, and under automatic ink-suction mode, the water imbibition of the inflow of washing stage and the quantity of clothing and clothing is proportionate, i.e. many or good water absorption of clothes amount, and the inflow of washing stage is just many.Adopt this water intake mode that the quantity of inflow and clothing and the water imbibition of clothing are matched, thus reduce the rinsing water amount of roller washing machine as far as possible.
S20 step: the computing unit of controller is according to inflow coefficient K pwash into water duration T with main zcalculate the rinsing inflow duration T of rinse stage p, computing formula is as follows:
T p＝K p*T z（3）
The derivation of computing formula:
The total inflow of rinse stage is:
L p＝F a*T p（4）
Formula (2) and formula (4) are substituted in formula (1), following formula can be obtained:
L p＝K p*L Z＝K p*F a*T z＝F a*T p（5）
As the flow of inlet water F of electromagnetic valve awhen change that is constant or flow is identical, can divide out in last equation in formula (5) F simultaneously a, just obtain formula (3).
As can be seen from above-mentioned derivation, at the flow of inlet water F of electromagnetic valve awhen change that is constant or flow is identical, master washes into water duration T zwith rinsing inflow duration T ppositive correlation, and proportionality coefficient is inflow coefficient K p.As long as the i.e. flow of inlet water F of electromagnetic valve ado not occur exception, record is main to be washed into water duration T z, just can calculate rinsing inflow duration T p, thus ensure that the water inlet total amount in drift ice stage and the quantity of clothing and water imbibition match.
S30 step: the controller of washing machine is according to the rinsing inflow duration T calculated pthe opening time of Controlling solenoid valve, the disposable water inlet completing described rinse stage.The water intake mode adopted in disposable water inlet compared to existing technology effectively can shorten the always consuming time of water inlet.In water inlet process, not rinsing of can only intaking, also can first intake, wait enter water reach a certain amount of after, rinsing limit, limit intake.
Shown in Fig. 3 and Fig. 4, the barrel washing machine water inflow amount provided in the barrel washing machine water inflow amount provided in the present embodiment and the graph of relation of time and prior art and the graph of relation of time are compared and can find out, in prior art, the inflow of rinse stage and flooding time relation curve are roughly in oblique line, therefore have sizable a part of water just to flow at the end of rinse cycle is fast.And the inflow of the present embodiment rinse stage and flooding time relation curve are broken line, namely at rinse stage front-end position, disposable water inlet arrives rapidly the water inlet total amount required for rinse stage, and after rinse stage, fragment position is then no longer intake.This water inlet water intake mode significantly can shorten flooding time.
Embodiment two
As shown in Figure 2, embodiment two is with the difference of embodiment one: in order to prevent the flow of inlet water F of electromagnetic valve aoccur abnormal and cause the result of calculation in S20 step inaccurate, after S10 step, before S20 step, can washing into water duration T main zcarry out reasonability judgement.
The method that reasonability judges is as follows:
S121: the water inlet higher limit T presetting the water inlet duration of washing stage in the memory cell of the controller of washing machine zmaxwith water inlet lower limit T zmin;
S122: master washes into water duration T by the arithmetic element of controller zwith water inlet higher limit T zmaxwith water inlet lower limit T zmincompare, comparative approach is as follows:
If T zmin< T z< T zmax, master washes into water duration T zvalue remain unchanged;
If T z≤ T zmin, get main washing into water duration T z=T zmin;
If T z>=T zmax, get main washing into water duration T z=T zmax.
Namely define main washing into water duration T zhigher limit and lower limit, thus overcome the flow of inlet water F of electromagnetic valve aoccur abnormal, master washes into water duration T zthe situation that cannot correctly record.
Embodiment two is attached to after in embodiment one, in S00 step, presets inflow coefficient K pwhile preset water inlet higher limit T zmaxwith water inlet lower limit T zmin.
Water inlet higher limit T zmaxwith water inlet lower limit T zminin order to prevent main washing into water duration T zthe abnormal and design limit value of detected value, this uses in the process of washing machine due to user the situations such as hydraulic pressure is low or cut off the water supply that may occur, may cause the flow of inlet water F of electromagnetic valve in these situations aoccur abnormal, thus occur that long master washes into water duration T z.And after entering rinse stage, hydraulic pressure recovers normal, if directly adopt long master to wash into water duration T zcontrol the water inlet of rinse stage, the water inlet excess of rinse cycle can be caused, even from overflow in cylinder, therefore design water inlet higher limit T zmaxwith water inlet lower limit T zminwinner is washed into water duration T zeffectively limited, thus avoided the abnormal situation of rinsing inflow.
Embodiment three
