    摘要： A washing machine control method accurately determines an amount of laundry in the washing machine, while driving a motor coupled to a drum under load, based on a computed average of pulse width modulation values at the time of stopping the drive of a motor and the motor's rotational angle as the motor freewheels to a stop, in order to conserve water and reduce the time required for performing a washing step. The method includes steps accelerating a motor to a target rotational speed, by periodically applying to the motor a pulse width modulation (PWM) signal having a predetermined duty ratio; storing in a memory a set of PWM values corresponding to the signal applied in the accelerating step, by sensing a rotational speed of the motor; outputting a PWM signal having a duty ratio of zero, after the sensed motor speed reaches the target rotational speed, to allow the motor to freewheel to a stop; computing an average of the stored PWM values; measuring a rotational angle of the motor as the motor freewheels to a stop; calculating a laundry amount estimation value based on the average of the stored PWM values and the motor's rotational angle; and determining a laundry amount by comparing the calculated laundry amount estimation value to a set of laundry amount reference values stored in a lookup table. The laundry amount estimation value equals w1PWMave+w2θmotor, where PWMave is the computed average of the stored PWM values, θmotor is the measured rotational angle, and w1, and w2 are weight constants.

    摘要： A drum-type washing machine, having a plurality of lifts installed on an inner circumferential surface of a drum, enables improved washing performance by providing friction plates on the inclined sides of each lift to increase a frictional force between the lift and laundry. Each lift includes a pair of inclined sides, disposed in opposition to each other to form a shape having a regular trapezoidal cross-section, for lifting laundry; and a pair of friction plates, consisting of a pair of opposing surfaces respectively provided on each inclined side and having a multitude of protuberances formed on both faces, to increase a frictional force with respect to the laundry.

    摘要： Disclosed herein is a drying unit for washing machines that is capable of fully drying the wet laundry using hot wind. A condensing duct and a drying duct are connected to a tub to circulate air in the tub. Between the drying duct and the condensing duct is disposed a drying fan. To the condensing duct is attached air cooling device for condensing air in the condensing duct by means of cool air. In the drying duct is mounted a drying heater for heating air in the drying duct to change the air into hot wind. During the drying operation of the washing machine, the air passing through the condensing duct is condensed by air, which is an unlimited resource. Consequently, consumption of energy and resources is minimized during the drying operation of the washing machine.

    摘要： Disclosed is a washing machine with a float type clutch in which a float connects a rotating force from a motor to a spin-drying shaft or disconnects the rotating force from the spin-drying shaft as it is upwardly or downwardly moved in accordance with supply or drainage of wash water, thereby allowing a washing operation or a dehydrating operation to be carried out, while forming an air layer for preventing wash water from reaching gears included in the float type clutch. A clutch control method in the washing machine with the float type clutch is also disclosed which involves an algorithm for determining whether or not the float is engaged with or disengaged from the spin-drying shaft, and executing an engagement or disengagement operation based on the determined result, and an algorithm for discriminating whether or not the engagement or disengagement is achieved in accordance with the float engagement/disengagement determining algorithm, thereby achieving an improvement in the reliability of float engagement/disengagement operations.
