ABSTRACT:
An automatic drying apparatus and a method of controlling the same is disclosed, enabling exact drying by using a humidity sensor (37) provided at a location having a stabilized output characteristic for automatic drying, the automatic drying apparatus including a heating apparatus (31) for heating air supplied into a drum into which a drying object is introduced, a fan (32) for forcibly drawing air into the drum; and a humidity sensor (37) provided between the fan (32) and the heating apparatus (37) such that a sensing surface is positioned to be parallel to a flowing direction of air passed through the fan (32), for outputting a sensing voltage value for determining dryness of the drying object.
