Laundry treating apparatus having induction heater and control method thereof

An object treating apparatus comprising:

• a tub;
• a drum rotatably disposed within the tub and configured to receive an object therein;
• an induction heater disposed on the tub and configured to heat an outer circumferential face of the drum facing the heater;
• a motor configured to rotate the drum;
• and
• a processor configured to control the induction heater to dry the object, and configured to operate the drum in a drum motion cycle with the induction heater being turned on, the drum motion cycle including:
• a conductive accelerating motion in which the drum is operated at a first RPM, the first RPM that is higher than a threshold spin RPM at which the drum is rotated to cause the object to come into contact with the drum and begin to rotate integrally with the drum;
• a space securing motion in which the drum is rotated at a second RPM, the second RPM that is higher than the first RPM of the conductive accelerating motion, wherein the space securing motion is performed subsequent to the conductive accelerating motion;
• and
• a rearrangement motion in which the drum is rotated at a third RPM that causes the object to tumble in the drum, wherein the rearrangement motion is performed subsequent to the space securing motion.
