Abstract: A method for controlling a dryer according to an embodiment of the present invention includes: an operation of, when a dusting mode is selected and a start command is input, rotating a drying drum at a first rotational speed V1 in a first direction for a first set time; an operation of, after the first set time elapses, rotating the drying drum at a second rotational speed V2 in a second direction opposite to the first direction for a first set time; and an operation of rotating a drying fan along with the drying drum, when the drying drum rotates in the second direction, dust staining on an object introduced into the drying drum is separated from the object, and when the drying drum rotates in the first direction, the separated dust is discharged to the outside of the drying drum by a forced air flow generated by the drying fan.
