  • a process control flow chart of a method for detecting imbalance of washing machine of the present disclosure which comprises following steps:
  • the eccentricity detection action in the test run of the dehydration process is performed.
  • the purpose of the eccentricity detection action in the test dehydration process is to detect the eccentricity state of the washing machine at the beginning of the dehydration process.
  • the eccentricity detection action in the test run of the dehydration process is that the sensor detection module immediately detects the eccentricity of the washing machine to get the initial eccentricity at the moment of rotation which is a slight rotation of the washing machine inner tub. Since the eccentricity detecting method of the present disclosure includes the eccentricity detection action in the test run of the dehydration process, the present disclosure can avoid "jumps and bangs" phenomenon due to a large eccentricity when the washing machine initially enters the dehydration stage. And this phenomenon in the dehydration stage of the existing washing machine is unavoidable and the frequency of occurrence is very high.

  • 551-S53 above can't solve the problem that the eccentricity exceeds the limit value, which is, when the low-speed eccentricity correcting operation is executed more than N times in S5, following steps are executed:
  • the eccentric correction method is that the control module orders the water inlet valve to supply water and re-wash to balance eccentricity.
  • the washing machine re-runs the dehydration process after balanced the eccentricity and drained. If the inlet water correction is repeated three times and still can't avoid “jumps and bangs" phenomenon, then the control module alarms.
  • the present disclosure simultaneously performs eccentricity detection and eccentricity correction in the high-speed dehydration stage.
  • the high-speed eccentricity correcting operation in S8 comprises following steps:
  • the correction result of the high-speed dehydration stage of the present invention ends with the high-speed dehydration action or a relative low-speed dehydration operation, it is mainly because the washing machine enters the high-speed dehydration stage only when the eccentricity in the low-speed stage of the present disclosure is smaller than the limit value. Therefore, strictly speaking, the high-speed eccentricity correcting operation of the present disclosure is intended to further ensure the smooth completion of the dehydration.
  • the relative low-speed dehydration operation mentioned in the present disclosure means that the dehydration speed is slightly smaller than the set rotational speed of the originally high-speed dehydration stage, but the lower rotational speed still satisfies the dehydration requirement and does not cause a "jumps and bangs" phenomenon. Therefore, the eccentricity correction in the high-speed dehydration stage of the present disclosure is achieved mainly by the control module commanding the motor to drive module to correct the acceleration and the speed.
