Abstract
The present invention is designed to detect instantaneous variations in the current flowing through a motor (5), instantaneous variations in the rotation of an agitating body (4), or instantaneous variations in the rotation of the motor (5) to thereby detect the washing load size. On the basis of the detection signal, the washing process is controlled to make it possible to properly set the washing bath ratio, detergent concentration, washing time, and number of revolutions of the fabrics being washed.
