Abstract

An oven includes an oven enclosure having a plurality of walls defining an oven cavity. The oven enclosure includes an oven door for accessing the oven cavity. The oven includes a venting assembly attached to a wall of the oven enclosure and in fluid communication with the oven cavity. The venting assembly includes an exhaust passage attached to the wall of the oven enclosure, the exhaust passage defining a flow path through which exhaust gas flows from the oven cavity. The venting assembly includes a flow control device positioned within the exhaust passage, the flow control device selectively restricting the passage of the exhaust gas through the exhaust passage. The venting assembly includes a fluid treatment structure disposed downstream from the flow control device within the exhaust passage, the fluid treatment structure altering characteristics of the exhaust gas flowing through the exhaust passage.
