Method of and apparatus for controlling washing operation of washer
 A method of and an apparatus for controlling a washing operation of a washer wherein a correlation coefficient is derived from data indicative of a turbidity of a washing water. The correlation coefficient is compared with reference data experimentally obtained, for determining all information required to control the washer such as the kind of a detergent used, an amount of the detergent, a washing time and a water flow intensity. The method includes a first procedure of checking an operation mode of the washer selected by a user, a second procedure of starting a washing operation when the operation mode checked is a washing mode, sampling, at predetermined time intervals, turbidity data supplied from turbidity sensing means equipped in the washer until the washer starts to operate at a stable state, and stores the turbidity data sampled, a third procedure of analyzing the turbidity data stored at the second procedure and operating a correlation coefficient of the turbidity data; and a fourth procedure of comparing the correlation coefficient operated at the third procedure with reference data and determining various information required to control the washer, based on the result of the comparison.
