Washing machine and control method thereof

摘要

A washing machine that controls water supply modes of washing and rinsing operations and a control method thereof. For the washing operation, the wetting of the laundry is improved through the supply of water in unidirectional rotation in which the water is supplied while a washing tub and a pulsator are simultaneously rotated in one direction. For the rinsing operation, laundry is quickly separated from the washing tub, such that the laundry is sufficiently mixed with the water, through the supply of water in unidirectional rotation and the supply of water in alternating-direction rotation in which the water is supplied while only the pulsator is rotated in alternating directions, thereby achieving rinsing utilizing water supply time, and, in addition, turnover of the laundry is smoothly achieved such that washing residues present on the laundry are effectively removed from the laundry, thereby improving rinsing efficiency.

主权项

1. A method of controlling a water supply of a washing machine including a washing tub and a pulsator rotatably installed in the washing tub, the method comprising:
a load detecting stage for detecting a weight of laundry placed in the washing tub; a target water level setting stage for determining a target water level according to the detected load; an initial water supply stage of supplying and storing water to a reference water level lower than the target water level while rotating the washing tub and the pulsator in one direction; a stopping stage for stopping the rotation of the tub and the pulsator while the water is continuously supplied to the tub; and a subsequent water supply stage of supplying and storing water to the target level in a state that the washing tub and the pulsator are stopped to provide for accurate determination of the target level.
