Abstract
A method of rinsing laundries in a washing machine with a tilted washing tub consisting of an outer tub and an inner tub is disclosed. In the method of this invention, a predetermined amount of water is primarily fed to the washing tub while constantly rotating the inner tub at an initial speed of no higher than a predetermined rpm, with the amount of water being predetermined in accordance with the weight of the laundries to be rinsed within the washing tub. Thereafter, a circulation-rinsing step is performed. In this step, the laundries are rinsed while rotating the inner tub at a second speed, with the water repeatedly circulated from the washing tub to a nozzle provided at the upper portion of the washing tub through a water circulation hose, and sprayed under pressure from the nozzle into the washing tub. After the circulation-rinsing step, the water is drained from the washing tub to the outside of the cabinet of the washing machine through a drain hose prior to rotating the inner tub at a third speed of no lower than the second speed so as to dewater the rinsed laundries. Thereafter, the process from the rinsing water feeding step to the dewatering step is repeated until a p…
