Abstract
Disclosed is a control method of a washing machine. The method includes performing first-stage rotation in which a drum is rotated at a predetermined rotational speed, performing second-stage rotation in which the drum is rotated at a first target RPM when a predetermined time has passed after the first-stage rotation ends, performing deceleration rotation in which the rotational speed of the drum is kept at a lower value than in the second-stage rotation, and performing third-stage rotation in which the drum is rotated at a second target RPM that is greater than the rotational speed of the drum in the deceleration rotation. Accordingly, it is possible to prevent laundry from being adhered to an inner surface of the drum during removal of moisture contained in laundry, and to achieve an increased contact area between laundry and hot air via uniform dispersion of laundry, resulting in enhanced laundry drying performance.
