Fig. 8 is the flow chart according to the control method of the washing machine of the embodiment of the invention, and is as shown in the figure, and this method comprises:
S801 is when clear water stops into water to a certain setting value (just not having sensor like water level).
S802, the power connection of control sensing device is the sensing device energising, washing machine controller obtains the turbidity voltage value of clear water this moment, is designated as Vz0.Begin to read the voltage value of electrical conductivity behind the 2s, read 20s continuously, getting the minimum of a value that records is the voltage value Vyt of the electrical conductivity of reality.Fig. 9 is the change curve according to the electrical conductivity voltage of the control method of the washing machine of the embodiment of the invention, and is as shown in Figure 9, and the actual value of Vyt is a minimum of a value, i.e. the minimum point of curve.
S803 reads the current water temperature T that sensing device records, and the power supply of control sensing device breaks off.
S804 carries out temperature-compensating to the voltage value Vyt of electrical conductivity and calculates electrical conductivity correction value Vy0, computing formula can for:
Vy0＝Vyt/(1+0.02*(T-25))
S805 according to electrical conductivity correction value Vy0, carries out the judgement of water hardness; Can preestablish the different threshold values of electrical conductivity, in different scopes, washings are divided into and be soft water, light water, hard water, utmost point hard water.
S806 is according to the injected volume of the corresponding washing agent of above-mentioned hardness of washing water correction.When slurry was soft water, the injected volume of throwing in washing agent in the parameter reduced than benchmark injected volume; When slurry was light water, the injected volume of throwing in washing agent in the parameter was consistent with the benchmark injected volume; When slurry is hard water; The injected volume of throwing in washing agent in the parameter increases than benchmark injected volume; When slurry was utmost point hard water, the injected volume of throwing in washing agent in the parameter increased than benchmark injected volume and the recruitment of recruitment when being hard water more than said slurry.Through this step, can change the addition of washing agent according to concrete water quality, thereby under the situation that guarantees washing quality, save the consumption of washing agent and slurry.It generally is the consumption that preestablishes a washing agent that washing machine adds washing agent; Confirm that according to the weight of laundry item needs add what part washing agent benchmark input just umber then; Therefore; Revising the recruitment of washing agent injected volume and a kind of concrete means of reduction is when slurry is soft water, lacks than benchmark input umber and throws in once; When slurry was light water, throwing in umber was that benchmark is thrown in umber; When slurry is hard water, throw in the umber input of Duoing once than benchmark, when slurry is utmost point hard water, throw in twice of the umber input of Duoing than benchmark.The concrete umber that increases and reduce can be set according to actual conditions.
S807 throws in washing agent automatically according to the impressions that calculates;
S808 continues the designated water level of intaking, and according to the program washing, finishes preceding 4 minutes and 2 minutes in washing, measures the turbidity average voltage level in this moment respectively, is designated as Vz1, Vz2, when measuring sensing device is switched at every turn, and test after accomplishing is cut off the power supply sensing device.Measuring the moment value of turbidity average voltage level before concrete washing finishes can according to circumstances set, and is not limited to the moment of preceding 4 minutes of washing end and 2 minutes.
S809, the current water temperature of read sensor with the sensor outage, is inquired about according to current water temperature, confirms the temperature compensation coefficient K2 of turbidity parameter.Temperature compensation coefficient according to testing different temperatures is made into form in advance, when specifically washing, according to the penalty coefficient of water temperature inquiry turbidity.Table 1 is a kind of question blank of temperature compensation coefficient:
Table 1
| Temperature (unit: degree centigrade) | COEFFICIENT K 2 |
| 0 | 0.94 |
| 10 | 0.95 |
| 20 | 0.97 |
| 25 | 1.00 |
| 30 | 1.02 |
| 40 | 1.09 |
| 50 | 1.19 |
| 60 | 1.35 |
| 70 | 1.59 |
| 80 | 2.02 |
| 90 | 2.90 |
The data of table 1 are the temperature compensation coefficients of certain concrete washing machine, for the different sensor parameter, can make an experiment to penalty coefficient in advance, and test value is made into the form like table 1 form, so that control is used.
S810 calculates the turbidity parameter Δ VZT1 of current washings, computing formula can for:
ΔVZT1＝(Vz1-Vz2)*K2。
S811 compares the turbidity parameter Δ VZT1 of current washings: begin rinsing during less than washing turbidity threshold value with preset washing turbidity threshold value; Continue to wash to Preset Time during greater than washing turbidity threshold value, the turbidity voltage value Vz3 that the sensing device measuring point arrives during record end recomputates turbidity parameter Δ VZT2=(Vz2-Vz3) the * K2 of washings.If Δ VZT2 is during less than threshold value, the beginning rinsing is if Δ VZT2 is greater than threshold value; Increase washing 2 minutes, the turbidity voltage value Vz4 that the sensing device measuring point of record washing after 2 minutes arrives, turbidity parameter Δ VZT3=(Vz3-Vz4) the * K2 of washings is recomputated in double counting; If greater than threshold value, continuing increases wash time, once tests in per two minutes; Repetition is according to the turbidity parameter of calculating washings, and less than threshold value, but wash time is no longer than the longest preset wash time until the turbidity parameter.The effect of step S811 is that turbidity changing value in blanking time is judged, turbidity changes hour in blanking time, stops washing.
S812 carries out rinsing, when the 1st rinsing finishes; Obtain the turbidity voltage value that sensing device is measured; And compensate according to above backoff algorithm and to obtain the turbidity parameter, this turbidity parameter and preset rinsing turbidity threshold value are compared, when less than this rinsing turbidity threshold value, get into dehydration procedure; Otherwise repeat the S812 step, until the turbidity parameter less than rinsing turbidity threshold value.Turbidity CALCULATION OF PARAMETERS method is consistent with the calculation procedure of step S811 among the step S812.The effect of step S812 is that turbidity changing value in rinsing blanking time is judged, the turbidity of washings changes hour in blanking time, stops rinsing.
S813 dewaters, and finishes whole washing process.
