Abstract: Disclosed is a method for controlling a laundry treating apparatus including an efficiency increasing operation and an efficiency maintaining operation, wherein the efficiency increasing operation includes a first efficiency increasing operation, wherein the controller controls the first driver such that an RPM of the drum corresponds to a first drum RPM and controls the second driver such that an RPM of the fan corresponds to a first fan RPM to perform a first efficiency increasing process, and a second efficiency increasing operation, wherein, after the first efficiency increasing operation, the controller controls the first driver such that the RPM of the drum corresponds to the first drum RPM and controls the second driver such that the RPM of the fan corresponds to a second fan RPM higher than the first fan RPM to perform a second efficiency increasing process.

Abstract: A clothes treating apparatus having a drying function includes: a cabinet; a drum provided within the cabinet; a heat-exchanger heat-exchanged with air exhausted from the drum; a lint filter disposed on an upstream side of the heat-exchanger with respect to flow of air exhausted from the drum to collect lint in the air; a spray tube spraying water to the lint filter to separate lint collected in the lint filter from the lint filter; and a lint collecting part at least partially provided below the lint filter or below the heat-exchanger to collect falling lint. Lint in condensate water may be collected, and thus, generation of a bad influence when condensate water is re-used may be suppressed. Also, contact between lint in drying air and the heat-exchanger may be restrained.

Abstract: A laundry apparatus is provided. The laundry apparatus may include a cabinet, a tub provided in the cabinet and defining an internal space, the tub having an opening formed in a front of the tub, a drum rotatably provided in the internal space of the tub and being made of a conductor, and an induction heater provided at an outer circumferential surface of the tub. The induction heater may heat the drum by generating an electromagnetic field and may include a coil that uses a supplied electric current to generate an eddy current in the drum by generating a magnetic field, and a coil arranging portion provided at the outer circumferential surface of the tub. The coil may be arranged on the coil arranging portion such that coils of the coil are spaced a predetermined distance apart from each other while being wound from a front direction to a rear direction of the tub.
