[0003] However, due to the uneven quality and uneven distribution of the foam, there is still a large error in the above method of obtaining the foam situation in the washing bucket according to the water level
Therefore, it is still difficult to effectively avoid the occurrence of dehydration with water and overflowing bubbles when the current washing machine is dehydrating.

The invention discloses a washing machine and a defoaming control method and device thereof in the dehydration process, wherein the method comprises the following steps: when the washing machine executes the dehydration process, judging the dehydration stage currently in which the washing machine is located, wherein each dehydration The phase corresponds to a current threshold; the working current of the dehydrating motor is detected in real time; whether the working current when the dehydrating motor runs smoothly is greater than or equal to the current threshold corresponding to the dehydration stage currently in the washing machine; if the working current of the dehydrating motor is running smoothly or greater The current threshold corresponding to the dehydration stage in which the washing machine is currently located controls the washing machine to perform a defoaming process. According to the method of the invention, it is possible to effectively prevent the occurrence of water dehydration and foaming in the washing machine, and to ensure safe and reliable operation of the washing machine.
Description
technical field [0001] The invention relates to the technical field of washing appliances, in particular to a defoaming control method in the dehydration process of a washing machine, a defoaming control device in the dehydration process of a washing machine, and a washing machine. Background technique [0002] At present, when the washing machine is dehydrating, it usually monitors the water level in the inner tub in real time through a water level sensor or a water level switch. [0003] However, because the quality of the foam is not uniform and the distribution is not uniform, there is still a large error in the above method of obtaining the foam situation in the washing tub according to the water level. Therefore, it is still difficult to effectively avoid the occurrence of dehydration with water and overflowing bubbles when the current washing machine is dehydrating. Contents of the invention [0004] The present invention aims to solve one of the technical problems...
