A method of controlling a motor-driven washing machine and a control system that controls a motor or any other components of the washing machine are disclosed. The method includes the steps of generating an interruption command for braking a motor in motion during a wash cycle, applying a phase-reversed voltage to a voltage input terminal of the motor in motion, and electrically shorting the input terminal of the motor for a predetermined period of time if a second phase-reversed voltage generated by the motor is higher than or equal to a critical voltage level. Using such method, a motor-clutch mechanism is prevented front generating a noise and from being damaged during a wash cycle.

A method of controlling a washing machine enables a memory function for each of various wash courses, whereby a customization of parameters is permitted for each course. The method washing machine has a memory function using a memory and is provided with a course start/pause button for selectively performing any one of the courses. The method includes steps of establishing a set of customized parameters for performing each course; first selecting one course for execution, the selected course corresponding to one set of parameters established in the establishing step; displaying default parameters of the course selected in the first selecting step; clearing the displayed default parameters and displaying, in response to a first selection of the memory function, the customized parameters corresponding to the course selected in the selecting step; and performing, upon an input of the course start/pause button, the selected course according to the displayed parameters. The establishing step is made up of steps of second selecting, from a predetermined set of parameters, the customized parameters for display; and storing in the memory the customized parameters selected in the second selecting step in response to a second selection of the memory function.

摘要:
The present invention provides a washer and washing cycle control method thereof, by which a laundry amount of a laundry can be measured prior to a water supply despite a dry state of the laundry and by which the waste of power consumption and unnecessary use of water can be prevented. The present invention includes a drum holding a laundry therein, a motor rotating the drum, and a control unit executing a sub-routine for measuring a laundry amount of the laundry prior to a water supply to the drum. And, the sub-routine includes the steps of applying a ramp drive voltage to the motor during an acceleration section to measure a motor RPM amount and a drive voltage amount during the acceleration section, stopping supplying the ramp drive voltage to the motor to measure a motor RPM amount of a deceleration section, and measuring a laundry amount of the laundry using the motor RPM amount of acceleration section, the drive voltage amount of the acceleration section, and the motor RPM amount of the deceleration section.
