A fluid spray system for a laundry appliance , the fluid spray system comprising: a blower configured to deliver process air through an airflow path ; a heat exchanger of the airflow path configured to dehumidify the process air and to form condensate that is delivered to a drain channel ; a lint filter that is disposed upstream of the evaporator for separating lint particles from the process air ; a diverter valve configured to selectively deliver fluid from the drain channel at least to a spray nozzle for delivering a flow of the fluid to a surface of the lint filter to separate lint particles from the upstream surface of the lint filter , wherein the fluid and the lint particles are directed to the drain channel , and wherein the fluid at least partially includes the condensate ; and a fluid outlet in selective communication with the diverter valve , wherein the diverter valve is operable to selectively and alternatively deliver the fluid from the drain channel to the spray nozzle and the fluid outlet ; wherein the spray nozzle is attached to an interior surface of the airflow path and includes a fluid inlet that extends through an interior surface of the airflow path ; and wherein the spray nozzle is configured to direct the fluid toward an upstream surface of the lint filter and into the drain channel ; and wherein the spray nozzle includes a laminar flow path that extends continuously from the fluid inlet to a deflecting surface that directs the fluid to the upstream surface of the lint filter , characterized in that an attachment surface of the spray nozzle includes a concentric sealing geometry that directly engages the interior surface of the airflow path , and the deflecting surface includes a multi-faceted surface configured to direct the fluid into a generally flat spray pattern. a blower configured to deliver process air through an airflow path ; a heat exchanger of the airflow path configured to dehumidify the process air and to form condensate that is delivered to a drain channel ; a lint filter that is disposed upstream of the evaporator for separating lint particles from the process air ; a diverter valve configured to selectively deliver fluid from the drain channel at least to a spray nozzle for delivering a flow of the fluid to a surface of the lint filter to separate lint particles from the upstream surface of the lint filter , wherein the fluid and the lint particles are directed to the drain channel , and wherein the fluid at least partially includes the condensate ; and a fluid outlet in selective communication with the diverter valve , wherein the diverter valve is operable to selectively and alternatively deliver the fluid from the drain channel to the spray nozzle and the fluid outlet ; wherein the spray nozzle is attached to an interior surface of the airflow path and includes a fluid inlet that extends through an interior surface of the airflow path ; and wherein the spray nozzle is configured to direct the fluid toward an upstream surface of the lint filter and into the drain channel ; and wherein the spray nozzle includes a laminar flow path that extends continuously from the fluid inlet to a deflecting surface that directs the fluid to the upstream surface of the lint filter , characterized in that an attachment surface of the spray nozzle includes a concentric sealing geometry that directly engages the interior surface of the airflow path , and the deflecting surface includes a multi-faceted surface configured to direct the fluid into a generally flat spray pattern. <EOS>
