摘要： Disclosed herein is a method of controlling a laundry dryer for generating high-temperature steam through a steam part and controlling each of rotation of a drum and rotation of a circulation fan. The method includes a steam drying procedure drying operation of increasing an internal temperature of the drum to dry an object to be dried, a steam drying procedure steam supply operation of supplying steam into the drum after the steam drying procedure drying operation, and a re-drying operation of supplying hot air into the drum after the steam drying procedure steam supply operation. When steam is sprayed from the steam part, the rotation of the drum is maintained, the rotation of the circulation fan is stopped, such that the steam is evenly supplied to the object to be dried, damage to the object is prevented, and sterilization of the object is enhanced.
