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.

Abstract: A washing machine, which does not have a narrowed portion on a throw-in and takeout route of washings, so that washings can be thrown in and taken out smoothly. The washing machine of the present invention comprises: an inner tub for accommodating washings; an outer tub for accommodating the inner tub; a housing comprising a housing body that is configured to accommodate the outer tub and is open at the upper end, a fixed lid fixed to the upper end of the housing body, and a movable lid that is movably disposed on the fixed lid, makes the upper end of the housing body selectively open towards the outside, and is capable of forming a lid side opening for making an inner tub side opening formed on the upper end of the inner tub open upwards; and a water supply unit provided on the fixed lid and used for supplying water to the inner tub, wherein the inner circumference of the lid side opening has a shape and size that make the inner tub side opening substantially open upwards.

Abstract: Disclosed is a washing machine including a transmission. The transmission includes: a variable driving side pulley unit arranged on a side of the output shaft; a variable driven side pulley unit arranged on a side of the input shaft; a driving belt capable of transferring the power between the variable driving side pulley unit and the variable driven side pulley unit; a rotating speed sensing part arranged in the driving side pulley unit and configured to change a pulley diameter with the increase of rotating speed; and a torque cam mechanism arranged between pulley hubs and that form a movable pulley and a fixed pulley of the driven side pulley unit and configured to control speed variation time when the pulley diameter varies in a reversing direction with the increase of the rotating speed via cam grooves and pins.

Abstract: A washing machine is provided. The washing machine adopts an induction motor to achieve efficient operation as that achieved by using a frequency converter. The washing machine includes: an input shaft configured to supply rotation power to a rotation part that rotates washings; an induction motor, configured to rotate in a forward direction and a backward direction and served as a power source of the rotation part; a transmission-arranged between an output shaft of the induction motor and the input shaft of the rotation part. The transmission is configured to change speed of the induction motor by decreasing a reduction ratio along with startup of the induction motor.

Abstract: A washing machine includes a washing machine body provided with a window portion at a front plate; an outer drum arranged in the washing machine body and having at least a transparent area formed by a transparent member at a portion corresponding to the window portion; a dewatering drum rotatably arranged in the outer drum; a motor configured to rotate to drive the dewatering drum; and a drum cleaning unit arranged between the outer drum and the dewatering drum and disposed at a position corresponding to the window portion and the transparent area and capable of abutting against an outer surface of the dewatering drum.

Abstract: The inventive washing/drying machine is capable of cleaning water while performing a laundry process, and uses water filtered by a filter for dehumidification in a drying process, thereby achieving water saving.
