Abstract

PURPOSE:To prevent the consumption of a necessary time or more and the generation of the vibration and noise of a vibrator by judging the amt. of washing on the basis of the time required until a motor reaches the predetermined number of rotations after it is turned ON in a spin-drying process and controlling the time subjecting a washing and spin-drying tub to inertial operation corresponding to the amt. of washing. CONSTITUTION:A signal control means 15 detects the time T required until a motor 5 reaches the predetermined number of rotations after it is turned ON in a spin-drying process to compare the same with a predetermined time Tn and, when the time T is shorter than the predetermined time Tn, that is, when the amt. of washing in a washing and spin-drying tub is small and inertial force is low, the time required until the motor 5 is braked after it is turned OFF at the time of the completion of spin-drying is set short. When the time T is longer than the predetermined time Tn, that is, a large quantity of washing is charged in the washing and spin-drying tub and inertial force is high, the time required until the motor 5 is braked after it is turned OFF at the time of the completion of spin-drying is set long. By this constitution, the spin-drying process can be completed without consuming a necessary time or more.

During the dehydration process, the motor is repeatedly turned on and off to drain water from the laundry little by little and spin the spinning speed. Gradually increase to a certain degree,
After performing so-called intermittent dehydration, continuous dehydration is performed, and at the end of the dehydration process, the washing and dehydrating tub is inertially operated, and when the rotation is almost stopped, the brake is applied to end the dehydration process. At this time, the time for inertial rotation of the washing / dehydrating tub was set according to each water level during washing.
