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 (54, 510) 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 (54, 510) to separate lint particles from the upstream surface (114, 540) of the lint filter (54, 510), 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 (54, 510) 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 (114, 540) 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 (54, 510) 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 (54, 510) to separate lint particles from the upstream surface (114, 540) of the lint filter (54, 510), 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 (54, 510) 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 (114, 540) 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.
