Title: Drum type washing machine
Inventor: MURAKAMI KAZUSHIGE
IPC: D06F37/22
Filed: 2000-03-30
Abstract: PROBLEM TO BE SOLVED: To surely prevent abnormal vibration of a drum and an outer tub during spin-drying. SOLUTION: Laundry is appropriately dispersed in the circumferential direction of the drum and the drum is rotated at a rotational speed (100 rpm) slightly higher than the rotational speed at which a centrifugal force and gravity acting on the laundry balance with each other. In that state, eccentricity is detected on the basis of the torque current component of a motor current, and if the eccentricity is equal to or less than a predetermined allowable value (determination 2, 3 or 4), the rotational speed of the drum is raised to 200 rpm. At this rotational speed, eccentricity is detected again on the basis of the torque current component, and if this eccentricity is equal to or less than the predetermined allowable value (determination 5), the rotational speed is further raised. Even if the same eccentricity is detected at the determination 2 and 3 or 4, the eccentricity appears in a greater amount at the determination 5 if eccentric load is located in the front part of the drum 5 than if it is located in the rear part of the drum, so a determination can be made as to whether or not drying should be started, in preparation for the worst case in which vibration increases.
