Abstract
A filtering system for a downdraft cooking appliance includes a filter assembly arranged directly below an air grill leading to a venting plenum. The filter assembly includes a liner which supports a filter element and is removably positioned inside the plenum. The filter element can be arranged inside the liner, attached thereto or insert molded into the liner material. The liner is preferably suspended from the air grill so as to be readily removable in unison with the grill for inspection, cleaning or replacement. In a preferred embodiment, the liner is formed with opposing, outwardly projecting flanges which slide into mating channels formed into the underside of the grill. With this arrangement, exposure of the wall surfaces of the plenum to the cooking byproducts is minimized, thereby greatly reducing any necessary cleaning of these surfaces.
