Abstract:
1. A laundry washing method for a washing machine that includes a tub and a drum arranged within the tub, the drum being rotatable about a horizontal axis, said method comprising: draining wash water from the tub prior to initiating a main spinning process; comparing a degree of laundry imbalance to a laundry imbalance reference level, when the degree of laundry imbalance is less than the laundry imbalance reference level, performing the main spinning process by spinning the drum at a high speed thereby extracting wash water from the laundry, based on the comparison of the degree of laundry imbalance to the laundry imbalance reference level, and when the degree of laundry is greater than the laundry imbalance reference level, comparing a laundry load to a reference laundry load; determining whether to spray wash water into the drum based on the comparison that the laundry load is greater than the reference laundry load; redistributing the laundry in the drum by repeatedly accelerating and decelerating the rotation of the drum; spraying wash water into the drum during the redistributing the laundry in the drum based on the determination of whether to spray wash water into the drum; and performing the main spinning process by spinning the drum at a high speed thereby extracting wash water from the laundry.
