Abstract

The invention provides a washing machine, a power failure memory control method thereof and a power failure memory control device of the washing machine. The power failure memory control method comprises the following steps of (S1) acquiring step marks corresponding to current running steps of the washing machine and preset parameters by using a controller; (S2) writing the step marks and the preset parameters into a preset storage unit by using the controller; (S3) acquiring the step marks and the preset parameters in the preset storage unit by using the controller after the washing machine is restarted; and (S4) acquiring running steps corresponding to the step marks according to the step marks and starting the washing machine according to the running steps and the preset parameters. By a step-by-step memorizing method, relevant information of the current running steps of the washing machine is stored in real time, the working state of the washing machine can be accurately recovered to a working state before power failure when the washing machine is restarted, and a power failure memory function is fulfilled; and circuits are simple in structure, the cost of the circuits is reduced, and the power failure memory control method is easy to implement.

Description

technical field [0001] The invention relates to the technical field of household electrical appliances, in particular to a power-off memory control method for a washing machine, a power-off memory control device for the washing machine, and a washing machine with the power-off memory control device. Background technique [0002] At present, the conventional design method of a washing machine with power-off memory function is: the electric control board is designed with a power detection circuit, and the main control chip of the electric control board monitors the power state in real time through the power detection circuit. The parameters are recorded in the memory chip; when the power supply is restored, the electric control board returns to the original operating state according to the parameters in the memory chip. However, this design method sets hardware circuits related to power monitoring on the electric control board, which has relatively high hardware requirements, ...
