Abstract: A method of controlling a washing machine includes washing laundry received in the drum by water mixed with detergent, performing a spin dry operation, and performing a rinse operation. The spin dry operation includes rotating the drum at a spin dry speed to allow the laundry to rotate along with the drum without falling from a highest point of the drum, and draining water from the tub while rotating the drum at the spin dry speed. The rinse operation includes decelerating the drum from the spin dry speed to a laundry adherence speed lower than the spin dry speed, supplying a first water supply to the drum, draining the first water supply from the tub, and supplying a second water supply to the drum.

Abstract: A method for controlling a laundry treatment apparatus is disclosed. The laundry treatment apparatus includes an upper treatment device and a lower treatment device. The upper treatment device includes a drying drum in which target laundry to be dried is placed, an upper driver to rotate the drying drum, a circulation passage unit through which air flows into or out of the drying drum, a heat exchanger to dehumidify and heat the air, and a steam generator to supply steam to the drying drum. The lower treatment device includes a tub to store wash water therein, a washing drum provided in the tub so that target laundry to be washed is put into the washing machine and the laundry is washed and dried, a tub heater provided in the tub to heat the wash water, and a lower driver to rotate the washing drum. The method for controlling the laundry treatment apparatus includes performing, by the lower treatment device, a washing course including a water supply step, a washing (rinsing) step, and a dehydration step, and performing, by the upper treatment device, a drying course including a hot air supply step, a fan operation step, and a dryness sensing step, wherein the lower treatment device performs the washing course by changing a configuration of at least one of an operation of the tub heater, an execution time of the washing course, and an operation of the lower driver according to a progress state of the drying course, thereby performing the washing course.
