Patent ID: 8418684

Claim:
A cooking oven, the cooking oven for catalytically treating emissions during a cooking event, the cooking oven comprising, in combination: a cooking chamber, the cooking chamber comprising a chamber inlet and a chamber outlet; and a catalytic conversion unit, the catalytic conversion unit comprising a unit inlet, a series of thermal radiation sources, a catalyst element, and a unit outlet, each thermal radiation source being oriented in a source plane, the source planes of each thermal radiation source being parallel to one another, each thermal radiation source having an upper portion, a lower portion, and an arched portion connecting the upper and lower portions, the thermal radiation source arranged perpendicularly with respect to emission flow, the catalyst element having a rectangular transverse cross section, said transverse cross section having a planar emission-receiving surface, the source planes being parallel to the emission-receiving surface for effecting variously angled radiant vectors from the thermal radiation sources, the catalytic conversion unit being in communication with the chamber outlet such that chamber-located emissions respectively conduct through the cooking oven through the chamber outlet, into the unit inlet, intermediate the upper and lower arms and arched portions of the thermal radiation sources, into the emission-receiving surface of the catalyst element, through the rectangular transverse cross section, through the unit outlet, and into air space adjacent the cooking oven, the catalyst element being maintained at a operative catalytic temperature via radiant heat energy provided by the upper and lower portions and arched portions of the thermal radiation sources respectively extending in the parallel source planes, the radiant heat energy thus converging toward a centralized portion of the catalyst element from variously angled upper directions, variously angled lower directions, and variously angled lateral directions respectively via the parallel upper portions, parallel lower portions, and parallel arched portions, the temperature-maintained catalyst element removes odors from emissions passing therethrough.
