1. A method for controlling a laundry treating apparatus, the laundry treating apparatus including a cabinet, a drum disposed rotatably inside the cabinet and configured to accommodate laundry therein, a fluid circulator including a condenser, a compressor, and an evaporator for circulating fluid therethrough, an air circulator including a fan configured to cause air heated through the fluid circulator to flow into the drum, and a driver including a first driver configured to rotate the drum and a second driver configured to rotate the fan, the method comprising:
performing an efficiency increasing operation by controlling the first driver and the second driver to increase a drying efficiency that is related to a humidity of the air inside the drum during a drying operation; and
performing an efficiency maintaining operation by controlling the first driver and the second driver after the efficiency increasing operation to maintain the drying efficiency during the drying operation,
wherein performing the efficiency increasing operation comprises:
performing a first efficiency increasing process by controlling the first driver to rotate the drum at a first drum revolutions per minute (RPM) and controlling the second driver to rotate the fan at a first fan RPM,
determining whether a duration of the first efficiency increasing process is equal to or greater than a first efficiency increasing process execution time, and
based on determining that the duration of the first efficiency increasing process is equal to or greater than the first efficiency increasing process execution time, performing a second efficiency increasing process by controlling the first driver to rotate the drum at the first drum RPM and controlling the second driver to rotate the fan at a second fan RPM higher than the first fan RPM.
