Abstract
A method of controlling a dryer includes rotating a drum within the dryer in a first direction, detecting at least one of temperature or relative humidity of air discharged from the drum while the drum is rotating in the first direction, and sensing occurrence of entanglement inside the drum by comparing a variation rate of at least one of the detected temperature or the detected relative humidity with a corresponding reference value. The method also includes, based on sensing that the entanglement has occurred, reversing a rotation direction of the drum by rotating the drum in a second direction that is opposite the first direction, and further, based on reversing the rotation direction of the drum upon sensing that the entanglement has occurred, maintaining the second direction of rotation of the drum for a preset time.
