Abstract
Disclosed herein is a control method of a washing machine that performs washing using bubbles. The control method may generate a large number of bubbles using a small amount of water to reduce water consumption and transmit detergent water to laundry placed in the washing machine effectively and rapidly using high-concentration detergent on the surfaces of the bubbles, thereby reducing time and energy consumption and improving washing efficiency. The bubbles may act as a cushion to reduce friction between laundry articles, thereby preventing expensive laundry (such as wool or silk) from being damaged due to the friction between the laundry articles and between the laundry and water and preventing damage to and deformation of general laundry when washing the laundry.
