PURPOSE:To remove stains almost completely from the laundry having a marked amt. of stains, by detecting, at the initial stage of washing, the turbidity of a washing bath with a turbidity sensor, and providing a control device feeding a detergent from an automated detergent feeder in accordance with the turbidity change. CONSTITUTION:The laundry is placed in a washing and dehydrating bath 2, and a water supply valve 10 is actuated to begin feeding water when a switch 15 is pushed. When the bath surface reaches a certain level (laundry detection level) 16, a level sensor 5 is actuated to close the water supply valve 10. A motor 13 rotates simultaneously with the stop of feeding water, and rotary blades 1 rotate to stir the laundry. With the beginning of stirring, the amt. of the laundry is detected, and water and a detergent are fed in amts. in accordance with the amt. of the laundry. The water level sensor 5 is actuated to stop feeding water when the bath surface reaches a water level appropriate for the laundry, and the motor 13 starts rotating to begin washing. With a prescribed elapse of time, the detergent is fed in accordance with the change of turbidity which a turbidity sensor 6 detects. Washing is finished after a prescribed elapse of time, and rinsing and dehydration are carried out, the entire washing process thus being finished. Complete removal of stains such as those with machine oil or mud becomes possible.
