Abstract

The invention discloses a fully automatic washing machine instantaneous power off memory circuit and a processing method thereof. The circuit consists of a single chip microcomputer IC1, a memory chip IC2 and a peripheral circuit. When the washing machine suddenly powers off, the single chip microcomputer IC1 records the current operating mode of the washing machine and sends the record to the memory chip IC2 for storage; and after the washing machine powers on again, the single chip microcomputer IC1 recovers the original operating mode of the washing machine. By adopting the memory circuit disclosed by the invention, the original periodic power off memory processing method of the fully automatic washing machine can be changed, the additional washing time caused by sudden power off can be reduced, electricity and water resources can be saved, the instantaneous power off memory function of the fully automatic washing machine can be realized and the requirements of customers can be met.

Description

technical field [0001] The invention relates to a memory circuit for instantaneous power failure of a fully automatic washing machine and a processing method thereof. Background technique [0002] The instantaneous power-off memory function of the automatic washing machine is that after a sudden power-off during the washing process, it can continue to run in the state when the power is off when it is powered on again. Currently, most of the washing machines with power-off memory functions on the market are staged. Electric memory, that is, stage-by-stage memory, no matter where the power is turned off in a stage, it will continue to run from the beginning of this stage when it is powered on again. [0003] In this way, in some areas where the voltage is unstable and easy to lose power, the washing time will be increased, and the electricity and water will be wasted. Contents of the invention [0004] The purpose of the present invention is to provide a fully automatic was...
