Abstract

A burner assembly for an oven appliance, the oven appliance defining a vertical direction, a lateral direction, and a transverse direction and including a cooking chamber, the burner assembly including a gas burner provided in the cooking chamber, the gas burner defining a clean air port, and a shutter housing attached to a first end of the gas burner, the shutter housing defining an air inlet in fluid communication with the clean air port, and wherein the air inlet is positioned below the clean air port along the vertical direction.

First claim

What is claimed is:

1. A burner assembly for an oven appliance, the oven appliance defining a vertical direction, a lateral direction, and a transverse direction and comprising a cooking chamber, the burner assembly comprising:
a gas burner provided in the cooking chamber, the gas burner defining a clean air port, the clean air port being provided along a bottom of the gas burner along the vertical direction; and
a shutter housing attached to a first end of the gas burner, the shutter housing defining an air inlet in fluid communication with the clean air port, and wherein the air inlet is positioned below the clean air port along the vertical direction and wherein each of the clean air port and the air inlet is provided below a midpoint of the gas burner along the vertical direction, wherein the shutter housing defines a first shutter housing and a second shutter housing slidably connected to the first shutter housing, and wherein the second shutter housing is configured to slide in the transverse direction axially along the gas burner.

2. The burner assembly of claim 1 , wherein the air inlet faces a bottom of the cooking chamber.

3. The burner assembly of claim 1 , further comprising a tray extending from the shutter housing in the transverse direction, wherein the gas burner is configured to contact the tray.

4. The burner assembly of claim 1 , wherein the shutter housing defines a mounting hole configured to receive the first end of the gas burner.

5. The burner assembly of claim 1 , wherein the gas burner is a broil burner mounted at a top of the cooking chamber.

6. An oven appliance defining a vertical direction, comprising:
a cabinet defining a cooking chamber therein;
a gas burner mounted within the cooking chamber, the gas burner defining a clean air port along a bottom of the gas burner; and
a rectangular shutter housing connected to the gas burner, wherein the shutter housing defines an air inlet in fluid communication with the clean air port, and wherein the air inlet is positioned below the clean air port along the vertical direction.

7. The oven appliance of claim 6 , wherein a height of the rectangular shutter housing in the vertical direction is greater than a diameter of the gas burner.

8. The oven appliance of claim 6 , wherein the rectangular shutter housing comprises a first shutter housing and a second shutter housing slidably received within the first shutter housing.

9. An oven appliance defining a vertical direction, comprising:
a cabinet defining a cooking chamber therein;
a gas burner mounted within the cooking chamber, the gas burner defining a clean air port; and
a rectangular shutter housing connected to the gas burner, wherein the shutter housing comprises
a first rectangular shutter housing; and
a second rectangular shutter housing slidably received within the first rectangular shutter housing, wherein the first rectangular shutter housing and the second rectangular shutter housing collectively define an air inlet through which air is delivered to the gas burner via the clean air port.

10. The oven appliance of claim 9 , wherein the air inlet is positioned below the clean air port along the vertical direction.

11. The oven appliance of claim 9 , wherein the second rectangular shutter housing is configured to slide in the transverse direction axially along the gas burner.

12. The oven appliance of claim 9 , wherein the rectangular shutter housing defines an air inlet, the air inlet being defined below the gas burner in the vertical direction.

13. The oven appliance of claim 12 , wherein the air inlet faces a bottom of the cooking chamber.

14. The oven appliance of claim 9 , further comprising a tray extending from the second rectangular shutter housing in the transverse direction, the tray defining a through hole therein, wherein the gas burner is configured to contact the tray.

15. The oven appliance of claim 9 , wherein the second rectangular shutter housing defines a mounting hole configured to receive the first end of the gas burner.

16. The oven appliance of claim 9 , wherein the gas burner is a broil burner mounted at a top of the cooking chamber.
