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.

1. A downdraft cooking appliance comprising:a cooktop formed with an opening; a plurality of heating elements arranged about the cooktop; a plenum including a plurality of walls disposed, at least in part, below the cooktop, said plenum having an opening disposed adjacent the plurality of heating elements; a blower exposed to said plenum for developing a venting flow of air containing cooking byproducts through the opening and into the plenum from above the cooktop during a cooking operation; a grill covering the opening, said grill having upper and lower surfaces; and a filter element suspended from the lower surface of the grill and projecting into the plenum, wherein the flow of air is directed through the filter prior to reaching the walls of the plenum in order to isolate the walls of the plenum from exposure to the cooking byproducts.
