ABSTRACT:
A method of controlling a washing machine is provided. The washing machine control method executes a washing process with a wobbling device. In the method, an operation of causing a washboard to wobble and an operation of rotating a spin-drying tub in the washing process are alternately performed. An operation of causing a washboard to wobble in a wobbling position and an operation of rotating a spin-drying tub in a washing process several times to mix laundry is performed, such that upper laundry and lower laundry can be uniformly washed, thus improving a laundry cleaning performance. Further, entangled laundry can be prevented from being rinsed by causing the washboard to wobble in the wobbling position before rinsing water is supplied.
