Clothes twisting detection device and the method of washing machine

a clothes twist sensing means for sensing a torque occurring at a drive shaft of the washer due to the twist of clothes, and generating a clothes twist signal according to the sensed impact distribution; a correlation coefficient operating means for converting the clothes twist signal into a digital signal indicative of a state value of the clothes twist signal, analyzing the state value of the clothes twist signal, and operating a corelation coefficient to be used for determining whether the clothes twist signal is a meaningful signal or a noise, based on the analysis; and a microprocessor for performing a control for executing a clothes untwisting mode, when the clothes twist signal is determined to be the meaningful signal, from the correlation coefficient outputted from the correlation coefficient operating means.
