Abstract: The present invention discloses a spin drying method using a spin dryer including a tub provided with a drainage passage, and a drum rotatably positioned in the tub, for containing laundry. The spin drying method includes a first step for accelerating the drum containing the laundry from a first rotation speed to a second rotation speed for spin drying, and a second step for finishing the spin drying and stopping the drum. The first step includes a process for determinating continuation of the acceleration. The determination process is conducted in at least one period included in the rotation speed range ranging from the first rotation speed to the second rotation speed.

Abstract: The present invention discloses a spin drying method using a tub (10) provided with a drainage passage, and a drum (20) rotatably positioned in the tub (10), for containing laundry. The spin drying method includes a first step for discharging wash water from the drum (20) to the tub (10) by rotating the drum (20), and a second step for discharging the wash water from the tub (10) to the drainage passage, by reducing a centrifugal force generated in the tub (10) by the rotation of the drum (20).

Abstract: A heater fixing unit of a drum-type washing machine is provided. The heater fixing unit more stably supports a heater installed in a dry duct to reduce vibration and a noise of the heater. For that purpose, the heater fixing unit includes a duct body, a heater, two or more fixing parts, and two or more clamp members. The duct body communicates with an inside of the drum. The heater is installed in an inside of the duct body to heat an air flowing in an inside of the duct body. The fixing parts protruded from two or more positions on an inner surface of the duct body. The clamp members fixedly support the heater.
