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.

Abstract: Disclosed is a control method of a laundry treatment apparatus including a drum for storing laundry, a duct provided outside the drum for guiding air discharged from the drum to the drum, a fan provided in the duct, a heat pump for performing heat exchange between air introduced into the duct and a refrigerant to dehumidify and heat the air, and a temperature sensing unit for measuring the temperature of the air introduced into the duct, the control method including operating the fan and the heat pump to supply heated air to the drum (a hot air supply step), measuring the temperature of the air discharged from the drum through the temperature sensing unit (a temperature measurement step), when the temperature of the air measured by the temperature sensing unit is equal to or higher than a predetermined reference temperature, measuring the amount of time for which the temperature of the air remains equal to or higher than the reference temperature (a time measurement step), and when the amount of time for which the temperature of the air remains equal to or higher than the reference temperature is equal to or greater than a reference amount of time, stopping the operation of the fan and the heat pump (a hot air supply completion step).
