A laundry treating apparatus, which can perform a laundry drying function, includes a tub in which washing water is accommodated, a drum rotatably installed in the tub, a duct installed on the tub and provided with an air-intake port and an air-inflow port for a flow of air, a blower fan installed in the duct to form the flow of air between the air-intake port and the air-inflow port, a heat exchanger installed in the duct so as to be supplied with cooling water and configured to perform heat exchange so as to cool the air transferred along an inside of the duct, and a heater installed in the duct to heat the air transferred along the inside of the duct.

A method of operating a laundry treating appliance with a treating chamber for treating a load of laundry the method comprising supplying a rinse to the treating chamber during a rinse cycle, spinning the treating chamber in an extraction cycle to remove excess moisture from the load of laundry, sensing a parameter indicative of a remaining moisture content value in the load of laundry, comparing the remaining moisture content value to a pre-determined remaining moisture content value.

A laundry treating apparatus includes a cabinet, a drum provided inside the cabinet and formed of a metal material for accommodating a treatment target, and an induction module spaced apart from an outer circumferential surface of the drum at a predetermined interval, inducing and heating the drum, where the induction module includes a base housing for accommodating a coil, a permanent magnet housing coupled with the base housing and provided with a holder in which a permanent magnet is accommodated, and a cover housing coupled with the permanent magnet housing, and the cover housing is coupled to the permanent magnet housing and therefore the permanent magnet is located between the permanent magnet housing and the cover housing. A joint force of the induction module may be enhanced to improve durability, and noise caused by vibration of a tub may be avoided.

A laundry treating appliance having a lint pelletizer whereby clothing fibers retained within a fluid can be extracted from the fluid and formed into a pellet. The laundry treating appliance can be a clothes washer or a clothes dryer. The clothes washer or clothes dryer can be a vertical or horizontal axis, either of which can be top-loading or front loading.

A washing machine with drying function may include a cabinet with a laundry insertion hole; a tub having a front opening and a back opening; a drum inside the tub, the laundry insertion hole, front opening, and drum being positioned so that laundry is insertable through the laundry insertion hole; a heated air supplying device with a heat exchange part above the tub, a front and back duct, and a blower fan to form an airflow, via the back and front duct, from the back opening to the heat exchange part, and then to the front opening; a lint filter in the back duct; a sensor to detect lint in the lint filter and produce a corresponding signal; a washing device to spray washing water toward the lint filter; and a processor to control the washing device to spray the washing water based on the signal produced by the sensor.

A laundry appliance includes a cabinet having a rotating drum operably positioned therein for processing fabric. At least one transducer is positioned proximate the drum that provides an ultrasonic resonance that is directed into an interior chamber of the drum. The ultrasonic resonance is adapted to be directed into damp fabric being treated within the interior chamber. The ultrasonic resonance serves to modify water trapped within the damp fabric into a substantially gaseous form.
