Abstract

An oven appliance includes a cabinet. A chamber is defined within the cabinet for receipt of food items for cooking. The oven appliance also includes a gas burner positioned proximate to a bottom portion of the chamber with a combustion products guide structure positioned and oriented to guide combustion products from the gas burner to an outlet proximate a back wall of the chamber.

First claim

What is claimed is:

1. An oven appliance, comprising:
a cabinet defining a vertical direction, a lateral direction, and a transverse direction, the vertical, lateral, and transverse directions being mutually perpendicular, the cabinet comprising a front portion spaced apart from a back portion along the transverse direction and a left side spaced apart from a right side along the lateral direction;
a chamber defined within the cabinet for receipt of food items for cooking;
a gas burner positioned proximate to a bottom portion of the chamber;
a combustion products guide structure positioned and oriented to guide combustion products from the gas burner to the chamber, the combustion products guide structure comprising a first duct and a second duct, the first duct extending from an upstream end proximate a first set of ports on a first side of the gas burner to a downstream end in the cooking chamber proximate a back wall of the chamber, the second duct extending from an upstream end proximate a second set of ports on a second side of the gas burner to a downstream end oriented towards a front of the oven appliance.

2. The oven appliance of claim 1 , wherein the gas burner is positioned proximate the back wall of the chamber.

3. The oven appliance of claim 1 , wherein the gas burner is the only combustive heat source for the chamber.

4. The oven appliance of claim 1 , further comprising a natural convection flow path defined through the chamber, the natural convection flow path extending from an origin at the outlet of the combustion products guide structure to a top wall of the chamber.

5. The oven appliance of claim 4 , wherein the natural convection flow path extends from the outlet, upward along the vertical direction across the back wall of the chamber, and forward along the transverse direction across a top wall of the chamber.

6. The oven appliance of claim 1 , further comprising a deflector extending downward into the chamber from a top wall of the chamber.

7. The oven appliance of claim 1 , further comprising a convection fan positioned above the outlet and below a top wall of the chamber, wherein the convection fan is downstream of the outlet and upstream of a top wall of the chamber.

8. The oven appliance of claim 7 , further comprising an electric heating element proximate to the convection fan.

9. The oven appliance of claim 1 , further comprising an electric heating element proximate to the top wall of the chamber.

10. The oven appliance of claim 1 , wherein the gas burner is the only heat source for the chamber.

11. An oven appliance, comprising:
a cabinet defining a vertical direction, a lateral direction, and a transverse direction, the vertical, lateral, and transverse directions being mutually perpendicular, the cabinet comprising a front portion spaced apart from a back portion along the transverse direction and a left side spaced apart from a right side along the lateral direction;
a chamber defined within the cabinet for receipt of food items for cooking;
a gas burner positioned below a bottom wall of the chamber;
a combustion products guide structure positioned and oriented to guide combustion products from the gas burner to a first outlet above the bottom wall and proximate a back wall of the chamber, and from the gas burner to a second outlet opposite the first outlet, the second outlet below the bottom wall.

12. The oven appliance of claim 11 , wherein the gas burner is positioned proximate the back wall of the chamber.

13. The oven appliance of claim 11 , wherein the gas burner is the only combustive heat source for the chamber.

14. The oven appliance of claim 11 , further comprising a natural convection flow path defined through the chamber, the natural convection flow path extending from an origin at the outlet of the first duct to a top wall of the chamber.

15. The oven appliance of claim 14 , wherein the natural convection flow path extends from the outlet, upward along the vertical direction across the back wall of the chamber, and forward along the transverse direction across a top wall of the chamber.

16. The oven appliance of claim 11 , further comprising a deflector extending downward into the chamber from a top wall of the chamber.

17. The oven appliance of claim 11 , further comprising a convection fan positioned above the outlet and below a top wall of the chamber, wherein the convection fan is downstream of the outlet and upstream of a top wall of the chamber.

18. The oven appliance of claim 17 , further comprising an electric heating element proximate to the convection fan.

19. The oven appliance of claim 11 , further comprising an electric heating element proximate to the top wall of the chamber.

20. The oven appliance of claim 11 , wherein the gas burner is the only heat source for the chamber.
