Method of compensating power failure of washing machine

Abstract

Disclosed herein is a method of compensating power failure of a washing machine. The method includes performing a selected cycle, determining whether power supply is interrupted during the selected cycle, storing information of a current performed cycle in a memory if the power supply is interrupted, determining whether the power supply is restarted, and restarting the stored cycle if the power supply is restarted.

1 . A method of compensating power failure of a washing machine, comprising:
 performing a selected cycle;   determining whether power supply is interrupted during the selected cycle;   storing information of a current performed cycle in a memory if the power supply is interrupted;   determining whether the power supply is restarted; and   restarting the stored cycle if the power supply is restarted.   
   
   
       2 . The method according to  claim 1 , wherein the restarting the stored cycle comprises performing the stored cycle from an initial stage of the stored cycle. 
   
   
       3 . The method according to  claim 1 , further comprising
 continuously performing the current performed cycle if the power supply is not interrupted.   
   
   
       4 . The method according to  claim 1 , wherein interruption of the power supply is determined according to whether a pulse by an alternating power is interrupted for a preset period of time.
