| 20090241267 | Control method of washing machine - 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. | 10-01-2009 |
| 20100236000 | Washing machine and control method thereof - Disclosed herein are a washing machine and a control method thereof. The control method effectively transmits high-concentration wash liquid to laundry, while minimizing the amount of water used, through washing using bubbles, and maximizes the increase in volume of the wash liquid rubbed on the inner circumferential surface of the drum using the generation of bubbles and the rotation of the drum to raise the water level of the wash liquid without additional water. | 09-23-2010 |
| 20110107617 | Misting control method of clothing dryer - Disclosed herein is a control method of clothing dryer that sprays an appropriate amount of mist based on the amount of clothing and dries the clothing at a fiber rearrangement temperature to remove wrinkles from the clothing. Standard regain of clothing is confirmed, mist is sprayed such that an amount of mist equivalent to approximately twice the standard regain reaches the clothing, and the clothing is dried at the fiber rearrangement temperature, whereby wrinkles are removed from the clothing. | 05-12-2011 |
