Abstract

An oven appliance includes a cabinet, a plurality of walls positioned therein to define a cooking chamber, and a door that provides selective access to the cooking chamber. An air passageway is defined through the door and around the cooking chamber between the plurality of walls and the cabinet. An air handler draws cooling air into the air passageway through an intake aperture and discharges the cooling air through a discharge aperture. A mesh screen is positioned over the discharge aperture of the air passageway to restrict access to hot surfaces within the cabinet.

First claim

What is claimed is:

1. A wall oven defining a vertical, a lateral, and a transverse direction, the wall oven comprising:
a cooking chamber positioned within a cabinet;
a door rotatably mounted to the cabinet for providing selective access to the cooking chamber;
an air passageway that wraps around the cooking chamber, extending from an intake aperture defined at a bottom of the door and a discharge aperture defined below the door;
a horizontal brace that extends between a left side and a right side of the cabinet along the lateral direction;
a mesh screen mounted to the horizontal brace over the discharge aperture of the air passageway; and
a flow diverter positioned in front of the mesh screen such that the mesh screen is behind the flow diverter and in front of the horizontal brace.

2. The wall oven of claim 1 , wherein the mesh screen defines a top hooked end that is positioned over a top of the horizontal brace.

3. The wall oven of claim 1 , wherein the mesh screen is attached to the horizontal brace with one or more mechanical fasteners.

4. The wall oven of claim 1 , wherein a bottom end of the mesh screen is curled over or blunted as a safety edge.

5. The wall oven of claim 1 , wherein the mesh screen defines an average aperture size of less than 0.339 inches, and wherein the mesh screen comprises a plurality of interwoven metal wires, each of the plurality of interwoven metal wires having a diameter of less than 0.025 inches.

6. An oven appliance defining a vertical, a lateral, and a transverse direction, the oven appliance comprising:
a cabinet;
a plurality of walls positioned within the cabinet to define a cooking chamber;
a door rotatably mounted to the cabinet for providing selective access to the cooking chamber;
an air passageway defined at least partially between the plurality of walls and the cabinet, the air passageway comprising an intake aperture and a discharge aperture;
a mesh screen positioned over the discharge aperture of the air passageway;
a horizontal brace that extends between a left side and a right side of the cabinet along the lateral direction, wherein the mesh screen is mounted to the horizontal brace; and
a flow diverter positioned in front of the mesh screen such that the mesh screen is behind the flow diverter and in front of the horizontal brace.

7. The oven appliance of claim 6 , wherein the air passageway is defined at least partially within the door and wherein the intake aperture is defined at a bottom of the door.

8. The oven appliance of claim 7 , wherein a flow diverter is positioned below a bottom of the door to separate the intake aperture from the discharge aperture.

9. The oven appliance of claim 1 , wherein the mesh screen defines a top hooked end that is positioned over a top of the horizontal brace.

10. The oven appliance of claim 1 , wherein the mesh screen is attached to the horizontal brace with one or more mechanical fasteners.

11. The oven appliance of claim 1 , wherein the mesh screen defines one or more clearance slots configured for receiving one or more mechanical fasteners when the mesh screen is in an installed position.

12. The oven appliance of claim 1 , wherein a bottom end of the mesh screen is curled over or blunted as a safety edge.

13. The oven appliance of claim 1 , wherein the mesh screen defines an average aperture size of less than 0.339 inches.

14. The oven appliance of claim 1 , wherein the mesh screen comprises a plurality of interwoven wires, each of the plurality of interwoven wires having a diameter of less than 0.025 inches.

15. The oven appliance of claim 1 , wherein the mesh screen is formed from metal.

16. The oven appliance of claim 1 , wherein the oven appliance is a wall mounted oven appliance.
