Abstract

Abstract A washing machine having a rinse mode for rinsing laundry placed in a tub of the washing machine. A rinse mode controller controls water supply to the tub and rotation of the tub to carry out a spin dry rinse mode. The spin dry rinse mode includes a first operation during which water is supplied into the tub while the tub is rotated and a second operation during which the supply oft water is stopped and the tub is rotated. The washing machine further includes a unit for detecting the amount of laundry put into the tub. A rinse time change controller controls the time for spin dry rinse mode in accordance with the amount of laundry detected. Thus, time can be saved and water conserved while still effectively rinsing the laundry.
