PURPOSE: A method is provided to reduce noise owing to vibration and the amount of consumed power by making an acceleration slope low until vibration noise is stabilized at the early stage of a washing rinsing operation. CONSTITUTION: A method of controlling motor velocity at washing rinsing operation comprises increasing motor rotation velocity according to a first increase rate up to a vibration noise stabilization region at the early stage of a washing rinsing operation. If the increased motor rotation velocity is over predetermined velocity, the motor is accelerated according to a second increase rate. Whether the motor rotation velocity increased in the step reaches target velocity(10rpm), is judged. If so, the motor velocity is controlled so that actual motor rotation velocity reaches the target velocity. If not, the motor continues to be accelerated. |
