Patent ID: 7138092

Claim:
A catalytic converter device for use in an oven vent comprising: a ceramic substrate having a first surface, a second surface, a circumferential surface, and a plurality of apertures extending through the substrate from the first surface to the second surface; a material coating the ceramic substrate, wherein the coating material comprises a catalyst; and a mounting ring comprising (i) a body in the shape of a ring, the body having an upper edge portion and a distal lower edge portion; (ii) one or more retaining tabs extending inwardly from the upper edge portion and at least one first lip extending inwardly from the lower edge portion, the one or more retaining tabs and the at least one first lip cooperating to secure the ceramic substrate therebetween within the ring about the circumferential surface of the ceramic substrate; and (iii) one or more locking tabs extending outwardly from the body and at least one second lip extending outwardly from the body, wherein an edge of an orifice in the oven vent can be locked into place between the one or more locking tabs and the at least one second lip to secure the catalytic converter device within the orifice of the oven vent such that gases flowing through the oven vent will pass through the apertures of the substrate.
