Title: Drum-type washer
Inventor: MURAKAMI KAZUSHIGE
IPC: D06F23/06
Filed: 2001-04-12
Abstract: PROBLEM TO BE SOLVED: To securely prevent generation of abnormal vibrations of a drum or outer tube in spin-drying, and to reduce the load applied to a bearing. SOLUTION: The drum 5 is mounted aslant so that a clothes slot 5a of the drum 5 faces upward. When spin-drying, the laundry is moved to the rear end surface side on the whole inside the drum 5 if the balance is adjusted by rotating the drum 5 at such a rotation speed that the centrifugal force acting on the laundry stored in the drum 5 is smaller than the gravity. Therefore, even if the eccentric load is generated due to the inclination of the laundry around the rotation axis to one side, the probability that the position of the laundry is in the rear of the drum 5 in the axial direction is extremely high. Accordingly, as the distance between the eccentric load and the bearing 10 is short, oscillating vibration is relatively small even if the eccentric load is applied, reducing the load to be applied to the bearing 10.
