Abstract

An oven appliance has a reflector positioned within a housing above an upper heating element. An air distribution manifold defines an entrance proximate a cooking chamber of the housing. A catalytic smoke reducer is positioned above the reflector at the entrance of the air distribution manifold. An air handler is operable to draw air from above the reflector through the catalytic smoke reducer and the entrance of the air distribution manifold.

First claim

What is claimed is:

1. An oven appliance, comprising:
a housing defining a cooking chamber;
an upper heating element positioned within the housing at a top portion of the cooking chamber;
a reflector positioned within the housing above the upper heating element;
a baking stone positioned within the housing at a bottom portion of the cooking chamber;
a lower heating element positioned within the housing below the baking stone;
an air distribution manifold mounted to the housing, the air distribution manifold defining an entrance proximate the cooking chamber of the housing;
a catalytic smoke reducer positioned above the reflector at the entrance of the air distribution manifold; and
an air handler operable to draw air from above the reflector through the catalytic smoke reducer and the entrance of the air distribution manifold,
wherein the reflector defines a plurality of holes for directing air within the cooking chamber of the housing through the reflector, and
wherein the holes of the plurality of holes are distributed on the reflector such that more of the holes of the plurality of holes are positioned at a rear half of the reflector than a front half of the reflector, the rear half of the reflector positioned at a rear portion of the cooking clamber, the front half of the reflector positioned at a front portion of the cooking chamber.

2. The oven appliance of claim 1 , wherein the housing defines an opening for accessing the cooking chamber, the opening positioned at the front portion of the cooking chamber.

3. The oven appliance of claim 2 , wherein the air distribution manifold is mounted to the housing at the opening of the housing, the air distribution manifold extending around the opening of the housing.

4. The oven appliance of claim 3 , wherein the entrance of the air distribution manifold is a first entrance and is positioned above the opening of the housing, the air distribution manifold defining a second entrance positioned below the opening of the housing.

5. The oven appliance of claim 4 , wherein the second entrance is contiguous with ambient air about the air distribution manifold and housing.

6. The oven appliance of claim 4 , wherein the catalytic smoke reducer is mounted to the housing between the first entrance of the air distribution manifold and the cooking chamber of the housing.

7. The oven appliance of claim 6 , wherein the housing comprises an air duct having a plurality of inlets positioned below the baking stone and a plurality of outlets positioned above the reflector, the air duct configured to receive air from below the baking stone at the plurality of inlets and direct the air into the cooking chamber of the housing above the reflector via the plurality of outlets.

8. The oven appliance of claim 7 , wherein the air distribution manifold defines an exit contiguous with ambient air about the air distribution manifold and housing, the air handler operable to urge air out of the air distribution manifold via the exit of the air distribution manifold.

9. The oven appliance of claim 8 , wherein the air handler is disposed within the air distribution manifold proximate the first entrance of the air distribution manifold.

10. The oven appliance of claim 1 , wherein the catalytic smoke reducer comprises a plurality of coated metallic foil layers.

11. The oven appliance of claim 10 , wherein the coating on the plurality of coated metallic foil layers is selected to complete combustion of hydrocarbons from the cooking chamber of the housing into carbon dioxide and water.

12. An oven appliance, comprising:
a housing defining a cooking chamber;
an upper heating element positioned within the housing at a top portion of the cooking chamber;
a reflector positioned within the housing above the upper heating element, the reflector defining a plurality of holes for directing air within the cooking chamber of the housing through the reflector;
a baking stone positioned within the housing at a bottom portion of the cooking chamber;
a lower heating element positioned within the housing below the baking stone;
an air distribution manifold mounted to the housing, the air distribution manifold defining an entrance proximate the cooking chamber of the housing;
a catalytic smoke reducer positioned above the reflector at the entrance of the air distribution manifold; and
an air handler operable to draw air from above the reflector through the catalytic smoke reducer and the entrance of the air distribution manifold,
wherein the holes of the plurality of holes are distributed on the reflector such that more of the holes of the plurality of holes are positioned at a rear half of the reflector than a front half of the reflector, the rear half of the reflector positioned at a rear portion of the cooking chamber, the front half of the reflector positioned at a front portion of the cooking chamber.

13. The oven appliance of claim 12 , wherein the housing defines an opening for accessing the cooking chamber, the opening positioned at the front portion of the cooking chamber, the air distribution manifold mounted to the housing at the opening of the housing such that the air distribution manifold extends around the opening of the housing.

14. The oven appliance of claim 13 , wherein the entrance of the air distribution manifold is a first entrance and is positioned above the opening of the housing, the air distribution manifold defining a second entrance positioned below the opening of the housing, the second entrance contiguous with ambient air about the air distribution manifold and housing, the catalytic smoke reducer mounted to the housing between the first entrance of the air distribution manifold and the cooking chamber of the housing.

15. The oven appliance of claim 14 , wherein the housing comprises an air duct having a plurality of inlets positioned below the baking stone and a plurality of outlets positioned above the reflector, the air duct configured to receive air from below the baking stone at the plurality of inlets and direct the air into the cooking chamber of the housing above the reflector via the plurality of outlets.

16. The oven appliance of claim 15 , wherein the air handler is disposed within the air distribution manifold proximate the first entrance of the air distribution manifold.

17. The oven appliance of claim 12 , wherein the catalytic smoke reducer comprises a plurality of coated metallic foil layers, the coating on the plurality of coated metallic foil layers selected to complete combustion of hydrocarbons from the cooking chamber of the housing into carbon dioxide and water.
