Abstract: A washing machine and a control method thereof to achieve washing performance using bubbles without damage to fiber structures of functional clothes. When a washing course of functional clothes is selected, a motor is frequently rotated at a period of a predetermined time or less, causing the clothes to uniformly adsorb the water. Thereafter, bubbles are generated and applied to the clothes. A drive operation rate of the motor is raised stepwise to wash the clothes to which the bubbles have been applied, so as to effectively remove sweat, contaminants, or the like contained in the clothes.

Abstract: A method for controlling a drying machine which includes a drum, a fan to circulate air within the drum, and at least one heater to heat air provided to the drum, and uses the motor and the at least one heater as a load, includes, upon receiving a drying process command from a user, receiving power rate information for each hour from an energy management system (EMS), recognizing current power rates on the basis of the power rate information for each hour, determining whether the current power rates are higher than reference power rates by comparing the current power rates with the reference power rates, and adjusting the operation rate of any one of the motor and the at least one heater when the current power rates are higher than the reference power rates. The drying machine changes the load operation rate before the power rates exceed the reference power rates, resulting in reduction in power consumption.
