Abstract

A baking drawer includes an oven cavity and a drawer assembly movable relative to the oven cavity between an extended position, where the drawer assembly is accessible by a user, and a retracted position, where the drawer assembly is located within the oven cavity. The drawer assembly has a bottom wall, two opposing sidewalls and a rear wall. A first vent is formed in the bottom wall, and a second vent is formed in the rear wall. The vents allow air to flow into and out of a ventilated region delineated by the bottom wall, the two sidewalls and the rear wall.

Claims (32)

1. A method of circulating air within a baking drawer, the baking drawer including an oven cavity and a drawer assembly movable relative to the oven cavity between an extended position, where the drawer assembly is accessible by a user, and a retracted position, where the drawer assembly is located within the oven cavity, the drawer assembly including a bottom wall, two opposing sidewalls and a rear wall, the method comprising:

causing air to flow into a ventilated region delineated by the bottom wall, the two sidewalls and the rear wall via a directional vent formed in the bottom wall, wherein the vent is a louver.

2. The method of claim 1 , further comprising:

redirecting air entering the ventilated region toward a center of the drawer assembly with the vent.

3. The method of claim 1 , wherein the vent constitutes a first vent, and the first vent is formed in the bottom wall proximate to a first one of the two sidewalls, the method further comprising:

causing air to flow into the ventilated region via a second vent formed in the bottom wall proximate to a second one of the two sidewalls.

4. The method of claim 3 , further comprising:

redirecting air entering the ventilated region toward the second one of the two sidewalls with the first vent; and

redirecting air entering the ventilated region toward the first one of the two sidewalls with the second vent.

5. The method of claim 1 , wherein the vent constitutes a first vent, the method further comprising:

causing air to exit the ventilated region via a second vent formed in the rear wall.

6. The method of claim 5 , wherein the second vent is at least 50% as large as the first vent.

7. The method of claim 1 ,

wherein the drawer assembly is formed from a single material.

8. The method of claim 7 , wherein the drawer assembly is formed from aluminized steel.

9. The method of claim 1 , further comprising:

heating the oven cavity with a heating element arranged below the bottom wall, wherein the baking drawer does not include a second heating element.

10. A method of circulating air within a baking drawer, the baking drawer including an oven cavity and a drawer assembly movable relative to the oven cavity between an extended position, where the drawer assembly is accessible by a user, and a retracted position, where the drawer assembly is located within the oven cavity, the drawer assembly including a bottom wall, two opposing sidewalls and a rear wall, the method comprising:

causing air to flow into a ventilated region delineated by the bottom wall, the two sidewalls and the rear wall via a first vent formed in the bottom wall; and

causing air to exit the ventilated region via a second vent formed in the rear wall, wherein the second vent has a different size or shape than the first vent.

11. The method of claim 10 , further comprising:

redirecting air entering the ventilated region toward a center of the drawer assembly with the first vent.

12. The method of claim 10 , wherein the first vent is formed in the bottom wall proximate to a first one of the two sidewalls, the method further comprising:

causing air to flow into the ventilated region via a third vent formed in the bottom wall proximate to a second one of the two sidewalls.

13. The method of claim 12 , further comprising:

redirecting air entering the ventilated region toward the second one of the two sidewalls with the first vent; and

redirecting air entering the ventilated region toward the first one of the two sidewalls with the third vent.

14. The method of claim 10 , wherein the second vent is at least 50% as large as the first vent.

15. The method of claim 10 , wherein the drawer assembly is formed from a single material.

16. The method of claim 15 , wherein the drawer assembly is formed from aluminized steel.

17. The method of claim 10 , further comprising:

heating the oven cavity with a heating element arranged below the bottom wall, wherein the baking drawer does not include a second heating element.
