ABSTRACT:
Clothes quality determining apparatus and method capable of analyzing a sensing signal indicative of the quality of clothes to be washed in a washer, to determine whether the clothes quality signal is a clothes quality signal or a noise, and controlling a rotation force of the washer according to the determined clothes quality signal, thereby minimizing a damage of clothes. The apparatus includes a clothes quality sensing unit for sensing the quality of clothes from the magnitude of an impact generated by the clothes and generating a clothes quality signal, a correlation coefficient operating unit for analyzing the clothes quality signal outputted from the clothes quality sensing unit and outputting a correlation coefficient for determining whether the clothes quality signal is a meaningful signal or a noise, and a microprocessor for controlling a rotation speed of the washer according to the clothes quality signal, when the clothes quality signal currently inputted is determined to be the meaningful signal, from the correlation coefficient.
