In the above-described embodiments, controller can carry out following several judgement according to the signal of telecommunication of photoelectric sensor module 5 outputs:
1. after having washed, when draining valve is opened, turn on sensor module 5 starts to detect hanger rod component 4 and is subject to force signal, along with washing inner bucket water is discharged, washtub weight saving, because draining valve draining change in flow is little, hanger rod component 4 is stressed to be reduced close to linearity, and the value of sensor assembly 5 outputs is also downward linearity curve; After washing inner bucket water is drained, washtub weight no longer changes, and hanger rod component 4 is stressed also no longer to be changed, and sensor assembly 5 is output as the straight line of the level of approaching.The data value collecting when controller no longer changes or changes when very little, judges that washing machine drainage completes, and action immediately can start to dewater.More accurate than existing level sensor determination methods by this determination methods, inner bucket water is drained just can perceive at once in washing, at once just can start to dewater, and can reduce wash time.
2. dehydration imbalance and dehydrating speed judgement.When laundry starts to dewater, because the weight of dehydration barrel and bucket undergarment has bias to a certain degree, be reflected in hanger rod component 4 stressed for and the oscillating curve of dehydration barrel synchronization, sensor output be the oscillating curve of certain frequency and amplitude.Whole dehydration is divided into 3 stages: dehydration boost phase, this motor speed accelerates to certain rotating speed since 0.The curve feature in this stage is that amplitude is higher, and frequency is lower.The amplitude of curve can characterize the magnitude of vibrations of washtub, and vibration has too greatly the danger of crash box body, need to stop dehydration the clothing in bucket is carried out to balance again.Whether the amplitude that controller is measured according to sensor assembly 5 is greater than threshold judges whether to stop dehydration and carries out balance again, the unbalanced method of this judgement washing machine is hit a barrel switch than the mechanical type generally adopting now and is compared more accurately, and reliability and modularization level are higher.If the value of sensor assembly 5 outputs is less than threshold, controller judgement washing machine does not hit casing risk, and dehydration is proceeded, and dehydration barrel enters stable state.Now sensor assembly 5 output valves are rendered as amplitude and approach, the curve that frequency and motor speed are synchronous.The amplitude of curve is larger, illustrates that the bias of bucket undergarment is larger.
3. clothing is weighed and moisture measuring and calculating.The washing machine test benchmark value a1 that do not put on more clothes, after putting on more clothes test intake after test value a2, test value a4 after draining completes, test value a3 has afterwards dewatered.Employing difference is calculated, and a2-a1 becomes positive correlation with interpolation clothes weight, and controller can be according to this value judgement clothes weight.(a3-a2) moisture content after/a2 reflection clothes dewatering, controller can judge that whether clothing moisture content is enough and judge whether washing machine stops dehydration according to this value, reach de-drying-stopping effect.
