Abstract:
A convection cooking appliance comprising:an oven cavity; an air channel assembly extending about at least a portion of and being in fluid communication with the oven cavity; a blower element for developing a flow of air within the air channel assembly and through the oven cavity; at least one heating unit for heating the flow of air; and a trap and filter unit including inner and outer radially concentric air baffles located within the air channel assembly, said inner baffle including a plurality of annularly spaced inner deflectors which are spaced by air inlet gaps, said outer baffle including a plurality of annularly spaced outer deflectors which are spaced by air outlet gaps, each said outer deflectors being radially spaced from and annularly overlapping respective ones of said inner deflectors, wherein the flow of air is directed into the inlet gaps, against respective ones of the outer deflectors whereupon cooking byproducts in the flow of air are deposited on the outer deflectors, subsequently against respective ones of the inner deflectors to separate further cooking byproducts from the flow of air, and through the outlet gaps.
