Description
Technical field
The present invention relates to a kind of clothes washing method with Turbidity measurement judgement, particularly relating to turbidity value can be according to laundry
The Turbidity measurement determination methods that environment is modified, and its use the method can be according to the dirty situation of change of cleaning solution
The washing machine that washing, rinsing stroke are controlled.
Background technology
In existing washing machine, judge, by the muddy degree detecting cleaning solution, the technology whether washing, rinsing complete
Being known, the clothing of such as Haier i.e. stops washing machine only.In order to test out the dirty degree of clothes, typically install on washing machine
Turbidity transducer detects.Turbidity transducer is indirectly judged the dirt of clothing by detecting the turbidity of washings
Degree, but owing to washing machine can produce a lot of line bits in washing process, also there is a lot of spots to solidify, pass through when draining
Just it is deposited on turbidity transducer during turbidity transducer.Because the operation principle of turbidity transducer is usually light transmission-type, pass
Sediment on sensor has just intercepted passing through of light, so that the test error of sensor becomes big.And roller washing machine
As all with heating function, the change of sensor for temperature is also more sensitive, also results in test error.
After detecting turbidity, the sensitivity to turbidity detector is readjusted, and bibliography Japan is public
The technical scheme that opening publication JP 57-66793 is provided is, with the carrying out of washing operating, dirt splits away off from clothing,
Turbidity of wash liquor increases, by detecting that the state that output voltage changes after stablizing with turbidity judges that washing completes.And for example
Bibliography 2 Patent No. ZL201110076814.X, invention entitled washing machine in first patent, disclosed washing machine bag
Include connect with outer barrel bottom drainpipe, be arranged in drainpipe and for according to light through the turbidity of degree detecting water
Test section, connection water intaking valve utilize Turbidity measurement portion to be supplied to the washing process initial stage with washing hose, the control unit of drainpipe
Water in drainpipe carries out Turbidity measurement, then uses water among washing process initial stage and final rinse cycle initial stage
That relatively low value of turbidity, makes a determination to the turbidity of rinsing liquid, improves Turbidity measurement precision, is controlled washing process,
The program needs increase the auxiliary system of a set of water inlet, and do not take into account the impact on turbidity for the temperature factor.
The method of testing of the turbidity of current washing machine, owing to not accounting for pollution and temperature drift etc. to sensor strip
The impact coming, so after some time of use, the error of turbidity test will differ greatly, and causes sentencing of dirt degree
Disconnected inaccurate.
Content of the invention
The present invention, based on above-mentioned defect of the prior art, provides a kind of clothes washing method with Turbidity measurement judgement,
Carry out correction and the compensation of test value to turbidity transducer under the long-time use environment different with heating-up temperature, make sensor
Deviation ensure in effective error range always, be the purpose of the present invention.
In order to realize the object of the invention, the present invention adopts the following technical scheme that
A kind of have the clothes washing method that Turbidity measurement judges, including washing procedure, rinsing program, dehydration procedure, Qi Zhong
According to Turbidity measurement and then judge washing course in washing procedure, described Turbidity measurement deterministic process is provided with determination turbidity correction
The step of coefficient, described Turbidity measurement deterministic process comprises the steps:
S1, clear water turbidity value V0Detection, determines adjusted coefficient K1=4/V0；
Before S2, washing terminate, Turbidity measurement V at least twicei、Vi+1,i=1,2…n；

S4, calculating turbidity difference Ti=(Vi-Vi+1) * K1* K2；
S5, judge washing course according to turbidity difference, select time delay to add and washes, or select to enter rinsing program.
Described washing terminate before twice Turbidity measurement setting procedure S2 be specially following two situation: S21, when washing be
Program initially set when normally washing, Turbidity measurement is before washing terminates the 4th minute, the 2nd minute twice;It S22, when washing is
The time delay of procedure Selection adds when washing, and Turbidity measurement refers to that last washing terminates and this time delay adds washing and terminates twice.
Described water temperature adjusted coefficient K2, water temperature and COEFFICIENT K2Proportional.
Described turbidity judges that washing course step is following two situation: S51, TiWhen≤0.06, select to enter rinsing journey
Sequence；S52、Ti> 0.06 when, select time delay to add and washes once, add and at the end of washing, detect current turbidity value Vi+1, and forward S3 to S5 step to
Rapid circulation；And also include that washing judges step total time, when washing reaches the setting time total time, enter rinsing program；
Otherwise, S3 to S5 step cycle is performed.
There is the clothes washing method that Turbidity measurement judges, enter in rinsing program, be provided with Turbidity measurement and judge makeover process, bag
Include following steps:
P1, rinsing terminate, Turbidity measurement VDrift i, i=1,2…n；
P2, detection current water temperature, determine adjusted coefficient K2；
P3, calculating turbidity difference DELTA VDrift i=(V0-VDrift i) * K1* K2；
P4, judge rinsing stroke according to turbidity difference, select again to rinse, or select to enter dehydration procedure.
Described turbidity judges that rinsing stroke step P4 is following two situation: P41, Δ VDrift iWhen≤0.2, select entrance de-
Water program；P42、ΔVDrift i> 0.2 when, select again rinse, forward P1 to P4 step cycle to.
Described turbidity judges that rinsing stroke step P4 also includes that rinsing total degree judges step, when rinsing total degree reaches to set
When determining number of times, enter dehydration procedure；Otherwise, P1 to P4 step cycle is performed.
The invention still further relates to a kind of washing machine, including casing, outer barrel, interior bucket, turbidity transducer, program control system, biography
Dynamic system, program control system uses the Turbidity measurement determination methods according to according to any one of technique scheme.
By using above-mentioned technical scheme, washing machine solves because turbidity transducer pollutes or temperature change is to turbid
Degree detection judges washing, the inaccurate problem of rinsing stroke, improves washing efficiency.
Brief description
