Abstract (en)

Disclosed is a control method of a laundry treatment apparatus including a drum (3) for storing laundry, a duct provided outside the drum for guiding air discharged from the drum (3) to the drum (3), a fan (75) provided in the duct (71), a heat pump (73) for performing heat exchange between air introduced into the duct (71) 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 (71), the control method including operating the fan and the heat pump (73) to supply heated air to the drum (a hot air supply step), measuring the temperature of the air discharged from the drum (3) through the temperature sensing unit (a temperature measurement step), when the temperature of the air measured by the temperature sensing unit (9) 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 (75) and the heat pump (a hot air supply completion step).
