Abstract

A home cooking appliance includes a housing having a rear wall, a cooking compartment in the housing, an exhaust channel that exhausts air from the cooking compartment, and an air gap insulator disposed between the rear wall and the air flowing in the exhaust channel and forming an air gap between the rear wall and the exhaust channel.

First claim

What is claimed is:

1. A home cooking appliance comprising:
a housing having a rear wall;
a cooking compartment in the housing;
an exhaust channel that exhausts air from the cooking compartment; and
an air gap insulator disposed in the exhaust channel between the rear wall and the air flowing in the exhaust channel and forming an air gap between the rear wall and the exhaust channel.

2. The home cooking appliance of claim 1 , further comprising:
a cooking surface on a top of the housing;
a rear vent trim on the top of the housing and at a rear side of the top of the housing, the rear vent trim having an opening in communication with the exhaust channel for permitting the air to exhaust from the housing.

3. The home cooking appliance of claim 1 , wherein the air gap insulator is configured to reduce an amount of heat transferred from the air in the exhaust channel to the rear wall.

4. The home cooking appliance of claim 1 , wherein the opening of the rear vent trim is formed in a front face of the rear vent trim.

5. The home cooking appliance of claim 1 , wherein the oven vent trim includes a deflector within the opening, the deflector configured to deflect the air being exhausted from the appliance in a predetermined direction.

6. The home cooking appliance of claim 5 , wherein the air gap insulator is positioned upstream of the deflector in the exhaust channel.

7. The home cooking appliance of claim 1 , wherein the air gap insulator is positioned on a surface of the rear wall that faces the exhaust channel.

8. The home cooking appliance of claim 1 , wherein the air gap insulator includes a plate portion having a surface arranged to be exposed to the air in the exhaust channel.

9. The home cooking appliance of claim 8 , wherein the plate portion is configured to be parallel to a flow of the air in the exhaust channel.

10. The home cooking appliance of claim 8 , wherein the air gap insulator includes:
a first flange on an upstream side of the plate portion, the first flange configured to guide the air over the plate portion.

11. The home cooking appliance of claim 10 , wherein the air gap insulator includes:
a second flange on a downstream side of the plate portion, the second flange configured to guide the air over the plate portion.

12. The home cooking appliance of claim 10 , wherein the first flange includes a surface that is angled with respect to the plate portion.

13. The home cooking appliance of claim 10 , wherein the first flange extends in a direction other than 90° from the plate portion toward the rear wall.

14. The home cooking appliance of claim 10 , wherein the first flange includes a surface that is curved with respect to the plate portion.

15. The home cooking appliance of claim 11 , wherein each of the first flange and the second flange is angled in a direction other than 90° from the plate portion toward the rear wall.

16. The home cooking appliance of claim 15 , wherein an angle of the first flange with respect to the plate portion is substantially equal to an angle of the second flange with respect to the plate portion.

17. The home cooking appliance of claim 15 , wherein an angle of the first flange with respect to the plate portion is different than an angle of the second flange with respect to the plate portion.

18. The home cooking appliance of claim 8 , wherein the air gap insulator includes an element for mounting the air gap insulator to the rear wall without direct physical contact between the plate portion and the rear wall.

19. The home cooking appliance of claim 11 , wherein the air gap insulator includes an element mounting the air gap insulator to the rear wall without direct physical contact between the plate portion and the rear wall.

20. The home cooking appliance of claim 18 , wherein the plate portion includes an emboss that receives a part of the element, and wherein a surface of the emboss facing the rear wall is spaced from the rear wall.

21. The home cooking appliance of claim 1 , wherein the air gap insulator includes:
a plate portion having a surface facing an interior of the exhaust channel and arranged to be exposed to the air in the exhaust channel;
a first flange on an upstream side of the plate portion; and
a second flange on a downstream side of the plate portion,
wherein the plate portion, the first flange, and the second flange cooperate with the rear wall to form the air gap between the rear wall and the exhaust channel, and
wherein the plate portion, the first flange, and the second flange substantially close off the air gap from the air in the exhaust channel.

22. The home cooking appliance of claim 21 , wherein an edge of an upstream end of the first flange is spaced from the rear wall, and
wherein an edge of a downstream end of the second flange is spaced from the rear wall.

23. The home cooking appliance of claim 21 , wherein an edge of the air gap insulator extending in a direction parallel to a flow of the air in the exhaust channel is spaced from other components of the appliance.

24. A home cooking appliance comprising:
a housing having a rear wall;
a cooking compartment in the housing;
an exhaust channel that exhausts air from the cooking compartment; and
an air gap insulator mounted on the rear wall of the housing,
wherein the air gap insulator includes:
a plate portion configured to be parallel to a portion of the rear wall upon which the air gap insulator is mounted and forming an air gap between the air gap insulator and the portion of the rear wall;
a first flange on an upstream side of the plate portion, the first flange including a surface that extends at an angle from the upstream side of the plate portion towards the portion of the rear wall and terminates at a first edge facing the rear wall and spaced from the rear wall;
a second flange on a downstream side of the plate portion, the second flange including a surface that extends at an angle from the downstream side of the plate portion to the portion of the rear wall and terminates at a second edge facing the rear wall and spaced from the rear wall; and
an element for mounting the air gap insulator on the rear wall without direct physical contact between the air gap insulator and the rear wall, the element including a first end mounted to a surface of the air gap insulator that faces the rear wall and a second end mounted on the portion of the rear wall, wherein the plate portion, the first flange, and the second flange cooperate with the portion of the rear wall to form the air gap, and the element is disposed in the air gap and arranged between the first edge of the first flange and the second edge of the second flange.

25. The home cooking appliance of claim 24 , wherein the air gap insulator substantially closes off the air gap from the air in the exhaust channel.

26. The home cooking appliance of claim 1 , wherein the air gap insulator includes a plate portion having a surface exposed to the air from the cooking compartment flowing through the exhaust channel.

27. The home cooking appliance of claim 1 , wherein the exhaust channel includes a front surface and a rear surface defining a flow path along which the air flows through the exhaust channel, and wherein the rear surface is formed at least in part by the rear wall of the appliance and at least in part by the plate portion of the air gap insulator.
