Abstract
Official abstract text for this publication.
An operating method for a laundry drier which has a rotatable drum mounted inside a main body, a heater for heating the air flowing into the drum; and a scent supply module for spraying scent into the drum, comprising: a drying step of drying the laundry by supplying hot air heated by the heater; a pre-treating step of tumbling the drum while supplying air with the heater off; and a scent treating step of spraying scent onto the laundry which has passed through the pre-treating step. Since the scent is sprayed on after the pre-treating step, the scent can be effectively deposited on the laundry.
