Laundry treating apparatus having induction heater

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 surface of the drum facing the heater;
• a first temperature sensor configured to detect a temperature of air in a space between the tub and the drum;
• a second temperature sensor configured to sense a temperature of washing water in the tub or a temperature adjacent to condensed water in the tub;
• and
• a processor configured to control an operation of the induction heater to heat the drum to heat and dry the object based on the temperature sensed by at least one of the first temperature sensor or the second temperature sensor,
• wherein, when a temperature sensed by the first temperature sensor is equal to or greater than a first temperature, the processor is configured to control to stop the operation of the induction heater or to lower an output of the induction heater;
• or
• wherein the processor is configured to perform repeatedly on and off of the operation of the induction heater in order to maintain the temperature detected by the first temperature sensor to the first temperature.
