    摘要： A full-automatic washing and drying machine has a drum (7) mounted in an outer tank (4) for rotation about a substantially horizontal axis, a reversible motor (15) operable at a fixed speed for driving the drum, and a power transmission device for transmitting the torque of the motor to the drum axle (13). The power transmission means include a reduction device (16). The motor and the reduction device are controlled by a control device such that, during washing and drying operations, the direction of rotation of an output shaft of the motor is switched in short periods while the speed-changing device transmits the rotation of the output shaft of the motor to the drum axle at a reduced speed, whereas, during dehydration operation, the motor operates unidirectionally and the speed-changing device transmits the unidirectional rotation of the motor output shaft to the drum axle with a speed reduction in an initial stage of the dehydration operation and, thereafter, without speed reduction.

    摘要： A speed variator for a laundry washing machine comprising a drum (6) mounted for rotation in a laundering tub (5) and adapted to be rotated at different speeds by a motor (7) via a transmission belt (8) interconnecting a driving pulley (9) of motor (7) and a driven pulley (10) associated with the drum. The driving pulley (9) of the speed variator is of the variable-diameter type and cooperates with a number of radially expandable flyweights (14). The driving pulley (9) and the motor (7) are carried by a rotatable carrier arm (19) having one of its ends hingedly connected to a lower portion of the tub (5), while its other end is connected to a piston (29) mounted for reciprocating displacement to different operating positions in a cylinder (39) connected through a solenoid valve (31) to the water supply circuit of the machine. The carrier arm (19) is biased by a torsion spring (25) to a position in which the driving pulley (9) is effective to keep the belt (8) under tension against the action caused by the radial expansion of the flyweights (14). The piston (29) acts on the carrier arm (19) in a manner to interdict or to permit the radial expansion of the flyweights (14) to varying degrees depending on the respective position of the piston. As a result, the effective diameter of the driving pulley (9) is varied by different degrees, permitting the drum (6) to be rotated at variable speeds.

    摘要： Disclosed is a washing machine which is properly treated noise and abnormal sound generated by a transmission when the transmission is introduced into the washing machine in order to efficiently use a motor. When the transmission (8) is introduced between an output shaft (72m) of the motor (72) and the input shaft (80m) of the rotation part (80), the transmission (8) includes: a variable driving side pulley unit (81) arranged on a side of the output shaft (72m); a variable driven side pulley unit (82) arranged on a side of the input shaft (80m); a driving belt (83) capable of transferring the power between the variable driving side pulley unit (81) and the variable driven side pulley unit (82); a rotating speed sensing part (81c) arranged in the driving side pulley unit (81) and configured to change a pulley diameter with the increase of rotating speed; and a torque cam mechanism (82f) arranged between pulley hubs (82d) and (82e) that form a movable pulley (82a) and a fixed pulley (82b) of the driven side pulley unit (82) 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 (82f1) and pins (82f2). The cam grooves (82f1) of the torque cam mechanism (82f) adopt the following structure: the cam grooves each have a first guiding groove (82f11) which is inclined in one direction relative to a specific generatrix (C) on the pulley hub (82e) and a second guiding groove (82f12) which is inclined in the opposite direction relative to the generatrix (C). The pins (82f2) are guided into the first guiding groove (82f11) when the pulley unit (82) performs forward-rotation speed variation, and are guided into the second guiding groove (82f12) when the pulley unit (82) performs backward-rotation speed variation.

    摘要： A washing machine and method for detecting imbalance of the washing machine, comprising the following steps: running a dehydration process, and performing an eccentricity detection action in a test dehydration process performing eccentricity detection test dehydration action; a sensor module performing a eccentricity detection action to detect the eccentricity of a machine in real time, and setting a preliminary dehydration curve; when running a low-speed drain, the sensor module detects the low-speed eccentricity in real time; determining whether the detected low-speed eccentricity exceeds a set value; if yes, then correcting the low-speed eccentricity, and if not, then proceeding to the next step; when running a high-speed drain, the sensor module detects a high-speed eccentricity in real time; determining whether the high-speed eccentricity of the high-speed drain exceeds a set value; if yes, then correcting the high-speed eccentricity, and if not, then ending with a high-speed draining. The method employs active and real-time detection, avoiding the "jumps and bangs" phenomenon, and extending the service life of a washing machine.

The drum washing machine includes: an outer tank (20), configured in a shell (10); a drum (22), configured in the outer tank (20) and capable of rotating by using a horizontal shaft or an inclination shaft inclining relative to a horizontal direction as a center; a rotating body (24), configured at a rear part of the drum (22) and having protruding parts (24a) in contact with washings on a surface of the rotating body (24); a driving part (30), capable of operating in a first drying form and a second driving form, wherein the first driving form refers to a driving form which enables the drum (22) and the rotating body (24) to rotate at different rotating speeds, and the second driving form refers to a driving form which enables the drum (22) and the rotating body (24) to rotate integrally at the same rotating speed; and a control part (801). Herein, the control part (801) enables the driving part (30) to operate in a biaxial driving form so that the drum (22) accelerates to rotate to an attaching speed at which washings can be attached to an inner circumferential surface of the drum (22), and detects the load quantity of washings in the drum (22) according to a rotating load applied to the drum (22) and the rotating body (24) that rotates relative to the drum (22) when the drum (22) accelerates to rotate to the attaching speed (S11 and S12).
