Method for alleviating vibration during dehydration of impeller washing machine

Abstract

The invention discloses a method for alleviating vibration during dehydration of an impeller washing machine. When the washing machine is in the dehydration period, the dehydration step is divided into a first dehydration stage and a second dehydration stage, wherein when the first dehydration stage is finished, and before the second dehydration stage starts, the motor speed of a washing drum is reduced to 100rmp or below, then the weight of clothings in the washing machine is sensed with a weight sensor, and finally the second dehydration stage is started once again, so that various exceptional vibration situations which can occur during the dehydration stage can be effectively sensed and avoided.

Description

technical field [0001] The invention relates to a washing method of a washing machine. Background technique [0002] The existing technology uses one stage of dehydration for the final dehydration, and there is no sense of cloth volume before the final dehydration, and the table value of the final dehydration is determined by the perceived value during the first washing and dehydration. In the prior art, when the final dehydration is performed, when the rotating speed reaches 450 for the first time, it will be maintained for a short period of time, then the rotating speed will be reduced to 270 rpm, and the rotating speed will be gradually increased to the set rotating speed again until the operation ends. The speed will be gradually increased during final dehydration, and will be maintained for a period of time when it reaches a certain speed, and the acceleration when each speed is increased is slightly different. [0003] In the existing technology, the final dehydration...

Problems solved by technology

[0003] In the existing technology, the final dehydration process is judged by the perceived value of the dehydrated cloth after washing. However, there may be some differences between the clothes and the state after washing and the state of the clothes before the final dehydration, and the final dehydration, because the final dehydration adopts a one-stage Dehydration, the state of the clothes during dehydration changes at any time. The state of the clothes at the time of dehydration and the state of the clothes before dehydration have changed a lot. If you still use the cloth amount perception value obtained before dehydration, it will cause great The deviation of the washing machine makes it impossible for the washing machine to judge some situations that may cause imbalance, and a large imbalance occurs during the dehydration process, causing the washing machine to move
