Method of controlling dryer and dryer stand

A method of controlling a dryer to discharge drying air, the dryer including a controller, a battery, a fan, and a heater, the method comprising:

• measuring, by the controller, a remaining charge amount of the battery provided in the dryer;
• detecting whether a drying operating mode is selected;
• determining whether the measured remaining charge amount is greater than a predetermined value for the selected drying operating mode;
• performing the selected drying operation mode when the measured remaining charge amount is equal to or greater than the predetermined value for the selected drying operating mode;
• performing a related drying operation mode when the measured remaining charge amount is less than the predetermined value;
• receiving a hot air mode signal;
• when the hot air mode signal is received, determining whether the measured remaining charge amount of the battery is higher than a first reference value;
• when the measured remaining charge amount of the battery is higher than the first reference value, operating the dryer to discharge the drying air, which is heated by the heater of the dryer;
• when the measured remaining charge amount of the battery is equal to or lower than the first reference value, operating the dryer to discharge the drying air, which is not heated by the heater of the dryer;
• receiving an air diffusion mode signal;
• when the air diffusion mode signal is received, determining whether the measured remaining charge amount of the battery is higher than a second reference value;
• when the measured remaining charge amount of the battery is higher than the second reference value, operating the dryer to discharge the drying air through an outlet and to simultaneously rotate the outlet;
• and
• when the measured remaining charge amount of the battery is equal to or lower than the second reference value, operating the dryer to discharge the drying air through the outlet which is held stationary.
