Self cleaning diverter valve

Abstract:

A fluid delivery system for a laundry appliance includes a blower that delivers process air along an airflow path. A drum receives process air to dry laundry. A heat exchanger dehumidifies the process air and removes condensate therefrom. A drain channel receives condensate from the heat exchanger. A pump directs fluid from the drain channel and along a fluid path. The fluid at least partially includes the condensate. A fluid diverter valve receives the fluid from the pump and selectively and delivers the fluid sequentially to a plurality of spray nozzles that direct a flow of the fluid onto a lint filter and toward the drain channel and a fluid outlet.
