Abstract
A quick-cook type convection cooking appliance includes an oven cavity in communication with an air channel assembly incorporating a radial byproduct trap and filter assembly defining a concentric ring-type baffle filter having two cylindrical sets of opposing air baffles. As recirculating air passes outwardly between deflectors of the baffle, the air is accelerated by a nozzle-type effect prior to impacting a center zone of an outer baffle deflector. This arrangement causes part of liquid and/or solid phases, such as grease, fats, and moisture, of the air flow to be deposited or trapped between the baffles. The air flow is then redirected back towards the inner baffle where, once again, the air impacts an inner baffle deflector that removes additional byproducts from the air. Finally, the air exits with a high uniform air flow pattern between respective deflectors of an outer baffle.
