Patent ID: 11041266

Abstract:
A washing machine is provided. The washing machine includes an input shaft, configured to supply a rotary power to a rotation part for rotating washings; a motor, configured to rotate in a forward and backward direction and served as a power source of the rotation part; a transmission arranged between an output shaft of the motor and the input shaft of the rotation part. The transmission includes a transformable driving side pulley unit disposed on the output shaft; a transformable driven side pulley unit disposed on the input shaft; a driving belt for  transferring power between the pulley unit.  The driving side pulley unit/driven side pulley unit is directly installed on the output shaft/input shaft by locating each end of the output shaft/input shaft at a movable pulley and a fixed pulley respectively, so that the driving side pulley unit/driven side pulley unit rotates integrally with the output shaft/input shaft.
