A laundry appliance includes a rotating drum for processing laundry. A blower directs process air through an airflow path that includes the rotating drum. A heat exchanger is positioned within the airflow path that dehumidifies the process air. A fixedly-secured lint filter captures lint from the process air at a position upstream of the heat exchanger. A fluid spray system has spray nozzles that deliver fluid to a surface of the fixedly-secured lint filter. Each spray nozzle of the plurality of spray nozzles directs captured lint away from the fixedly-secured lint filter.

A laundry processing apparatus includes a wall defining a condensed water collecting space configured to collect condensed water. The wall has an opening hole that is open to communicate with an inside of a cabinet of the laundry processing apparatus and that is configured to open and close by an opening and closing unit. Therefore, when the laundry processing apparatus is not operated, the condensed water remaining in the condensed water collecting space is quickly removed by air inside the cabinet, and during drying operation or drainage operation, the opening hole is closed by the opening and closing unit, pressure leakage is prevented for a space where air flows or a space where the condensed water is pumped.

Disclosed is a dryer operating method that is useful in a 5G environment provided for the Internet of Things. The dryer of the disclosure includes a heating device, a tumbler connected to the exit of the heating device, a fan connected to the exit of the tumbler, a heat exchanger disposed in a flow line of a working fluid connected to the exit of the fan, and a compressor having an entrance connected to the flow line connected to the exit of the fan and an exit connected to the entrance of the heat exchanger. The method of the disclosure includes heating the working fluid using the heating device, reducing the pressure in the tumbler by discharging a portion of the working fluid in a circulation line to outside using the compressor, drying an object to be dried received in the tumbler, and cooling the object to be dried.

A dryer includes a dehumidification filter containing a temperature responsive material with an upper critical solution temperature, a fan sending gas through the dehumidification filter, a heater heating the dehumidification filter, and a controller controlling the fan and the heater and switching an operation mode of the fan and the heater between a drying mode and a regeneration mode, wherein, in the drying mode, an object to be dried is dried with the fan sending the gas through the dehumidification filter that is heated by the heater to temperature higher than or equal to the upper critical solution temperature, and in the regeneration mode, the dehumidification filter is regenerated with the fan sending the gas through the dehumidification filter at temperature lower than the upper critical solution temperature.

A dryer including: a drum; a duct connected to the drum; a compressor connected to an evaporator and a condenser provided inside the duct; a heater provided inside the duct; a fan provided inside the duct; a motor to rotate the fan; and a controller configured to perform a first operation of operating the compressor, the heater, and the motor based on no object being inside the drum, and a second operation of operating the heater and the motor without operating the compressor. The dryer may sterilize the inside of the dryer, particularly, a flow path through which humid air passes.
