Abstract
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.
