摘要： A method for controlling the dehydrating operation of a drum type washing machine includes a pre-acceleration step for accelerating a drum to a predetermined control starting speed, and a main accelerating step for accelerating the drum from the control starting speed to a target speed along a linear locus having a preset acceleration slope. A deviation of the center of gravity of the laundry and a pre-spinning time period are reduced in the aforementioned control method.

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 steam generator for a washing machine comprises: a hermetic container provided with a water supply port for supplying water and a steam exhaustion port for exhausting steam; a heater arranged in the hermetic container for heating water supplied into the hermetic container; and a drain unit for draining residual water inside of the hermetic container outwardly. According to this, residual water inside of the steam generator is outwardly exhausted thus to maintain cleanness of the steam generator. Also, the drain unit using a siphon principle is installed thus to naturally exhaust residual water inside of the steam generator without an additional valve device, thereby reducing a fabrication cost.
