Abstract: An object treating apparatus includes a tub, a rotatable drum for receiving an object, an induction heater for heating an outer circumferential face of the drum, a motor for rotating the drum, an upper temperature sensor, a lower temperature sensor, and a processor. The upper temperature sensor detects a temperature of a space between the tub and the drum. The upper temperature sensor is disposed inside the tube at an upper portion of the tub. The lower temperature sensor detects a temperature around condensed water at a bottom of the tub. The lower temperature sensor is disposed inside the tub at a lower portion of the tub. The processor can determine a drying ending timing based on the temperatures detected by the upper and lower temperature sensors.
