Dryer and method for controlling the same

A dryer, comprising:

• a drying electrode portion comprising a drying electrode;
• a sterilizing electrode portion comprising a sterilizing electrode;
• a condensing electrode portion comprising a condensing electrode;
• a radio frequency (RF) power supply including a first RF power supply and a second power supply configured to amplify an input signal to generate an RF signal;
• a switch portion comprising a switch configured to electrically connect or disconnect the drying electrode portion, the sterilizing electrode portion or the condensing electrode portion to/from the RF power supply;
• and
• at least one processor, comprising processing circuitry, individually and/or collectively, configured to cause the dryer to:
• control the switch portion to allow the first RF power supply and the second RF power supply to apply a first RF signal to the drying electrode portion to perform a drying mode, and
• control the switch portion to allow one of the first RF power supply and the second RF power supply to apply a second RF signal to the condensing electrode portion, or to allow a remaining one of the first RF power supply and the second RF power supply to apply a third RF signal to the sterilizing electrode portion to perform at least one of a condensing mode or a sterilizing mode.
