PCT No. PCT/JP90/01510 Sec. 371 Date Jul. 19, 1991 Sec. 102(e) Date Jul. 19, 1991 PCT Filed Nov. 20, 1990 PCT Pub. No. WO91/07537 PCT Pub. Date May 30, 1991.The present invention relates to a control apparatus for a washing machine, which judges the type of dirt and quantity of dirt, etc. in laundry items to be washed, to thereby ensure optimum results for the finished washed items. In addition, control of washing is executed by judgement operations executed at high speed, to enable highly accurate real-time control. The apparatus is provided with a transmission factor detection apparatus (19) for detecting the optical transmission factor of the washing liquid within a tub of the washing machine. The optical transmission factor detected by the transmission factor detection apparatus (19) and the duration of a saturation interval, which elapses from the start of washing until a condition of saturation of the optical transmission factor is attained, are used as information representing the type of dirt and quantity of dirt, etc. A microcomputer (16) determines the duration of a washing operation, etc., from control tables, by using the saturation interval and optical transmission factor.
