Abstract:
1. A method of controlling a washing machine that includes a drum, the method comprising: rotating the drum at a first speed at which part of laundry within the drum tumbles and another part of the laundry adheres to the drum; detecting an unbalance amount of the drum while the drum rotates at the first speed; when the unbalance amount of the drum detected at the first speed is a first specific value or less, increasing the rotational speed of the drum from the first speed to a second speed so that substantially all of the laundry adheres to the drum; detecting an unbalance amount of the drum while the rotational speed of the drum increases from the first speed to the second speed; when the unbalance amount of the drum detected while the rotational speed of the drum increases from the first speed to the second speed is a second specific value or more, decelerating the rotation of the drum below the first speed; increasing the rotational speed of the drum to the first speed after decelerating the rotation of the drum below the first speed; and again rotating the drum at the first speed, wherein a rising slope of the rotational speed of the drum while the rotational speed of the drum increases after decelerating the rotation of the drum below the first speed is different from the rising slope of the rotational speed of the drum during the preceding increase of the rotational speed of the drum to the first speed.
