Radial byproduct trap and filter assembly for a cooking appliance

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 of the inner and outer deflectors including a base portion and first and second angled end portions, said first and second angled end portions of the inner deflectors project radially outward, while said first and second end portions of the outer deflectors project radially inward, wherein the inner and outer baffles define a serpentine path for the flow of air through the trap and filter unit.

A method of cleaning a recirculating air flow in a convection cooking appliance including an oven cavity, at least one heating element and a blower for generating the air flow inside an air channel assembly leading to and from the oven cavity comprising:

• guiding the air flow, containing cooking byproducts, from the oven cavity to a trap and filter unit positioned in the air channel assembly;
• directing the air flow to impact an outer radial baffle of the trap and filter unit to cause cooking byproducts in the air flow to be deposited on the outer baffle;
• redirecting the air flow to cause the air flow to impact an inner radial baffle of the trap and filter unit to cause additional cooking products in the air flow to be deposited on the inner baffle;
• and
• further redirecting the air flow radially outward to exit the trap and filter unit.
