The invention discloses an anti-collision protection method for a washing machine and a washing machine. The method includes the following steps: S1, when the washing machine starts to execute the dehydration program, detect the current of the motor in the washing machine in real time; S2, when the rotation speed of the inner barrel of the washing machine is less than the preset When rotating speed, obtain the current change amount of the motor during the mechanical cycle based on the current of the motor, and determine the eccentricity of the washing machine based on the current change and the load of dry clothes; S3, if the eccentricity of the washing machine is greater than or equal to the highest dehydration gear of the washing machine Preset the eccentricity to control the washing machine to stop dehydration and shake out to protect the washing machine from collision. The anti-collision protection method of the washing machine according to the embodiment of the present invention realizes the anti-collision protection of the washing machine, improves the intelligence of eccentricity sensing in the low-speed stage of dehydration of the washing machine, and does not require additional hardware, thereby improving the market competitiveness of the washing machine.
Description
technical field [0001] The invention relates to the technical field of electrical appliances, in particular to an anti-collision protection method for a washing machine and the washing machine. Background technique [0002] In the low-speed stage of the dehydration process of the pulsator washing machine, if the eccentricity is too large, in order to prevent the washing tub from colliding with the cabinet, the pulsator washing machine in the related art usually implements anti-collision protection by installing a door switch part. At present, most top-loading washing machines on the market are equipped with mechanical door switches to protect the washing machine from impact. However, this solution of protecting the washing machine from impacts is not smart and takes a certain share of the cost of the washing machine. [0003] Therefore, the scheme for protecting the washing machine from impact in the related art needs to be improved. Contents of the invention [0004] Th...
