Abstract

A home cooking appliance includes a housing, a cooking surface on a top of the housing, a cooking compartment in the housing, a cooling air system conveying air through the housing, and a rear exhaust louver on the housing, the rear exhaust louver in fluid communication with the cooling air system and exhausting a portion of the air from the housing in an upward direction substantially in a plane of the rear wall of the housing to increase air pressure along a kitchen wall adjacent to the rear wall of the appliance.

First claim

What is claimed is:

1. A home cooking appliance comprising:
a housing;
a cooking surface on a top of the housing;
a cooking compartment in the housing;
a cooling air system having a cooling fan conveying air through the housing;
a rear vent trim at a rear side of the top of the housing; and
a rear exhaust louver on the housing, the rear exhaust louver in fluid communication with the cooling air system and exhausting a portion of the air received from the cooling fan under pressure from the housing in an upward direction substantially in a plane of a rear wall of the rear vent trim to form a pressurized air wash blowing in the upward direction between a rear wall of the rear vent trim and a kitchen wall adjacent to the rear wall of the appliance.

2. The home cooking appliance of claim 1 , wherein the rear exhaust louver is disposed on an exterior surface of a rear wall of the housing, the rear exhaust louver exhausting the portion of the air under pressure from the housing to form the pressurized air wash originating along the exterior surface of the rear wall of the housing and blowing in the upward direction along the exterior surface of the rear wall of the housing and the pressurized air wash continuing upward along an exterior surface of the rear wall of the rear vent trim.

3. The home cooking appliance of claim 1 , wherein the upward direction is a vertical upward direction.

4. The home cooking appliance of claim 1 , wherein the upward direction is a direction extending at an angle other than a vertical direction and a horizontal direction.

5. The home cooking appliance of claim 1 , wherein the rear exhaust louver is disposed at a central region with respect to a width of the housing.

6. The home cooking appliance of claim 1 , wherein the rear exhaust louver is disposed at an outer region with respect to a width of the housing.

7. The home cooking appliance of claim 1 , wherein the rear exhaust louver is disposed on the rear wall of the housing and directs the air in the upward direction along an exterior surface of the rear wall of the housing.

8. The home cooking appliance of claim 7 , wherein the rear exhaust louver is disposed at a central region with respect to a width of the rear wall of the housing.

9. The home cooking appliance of claim 7 , wherein the rear exhaust louver is disposed at an outer region with respect to a width of the rear wall of the housing.

10. The home cooking appliance of claim 7 , wherein the rear exhaust louver includes a deflector that directs the air from the rear exhaust louver in the upward direction along the exterior surface of the rear wall of the housing.

11. The home cooking appliance of claim 7 , wherein the rear exhaust louver includes at least one divider that divides the air from the rear exhaust louver into a plurality of flow paths.

12. The home cooking appliance of claim 1 , wherein the rear exhaust louver comprises: a plurality of rear exhaust louvers on the housing, each of the plurality of rear exhaust louvers in fluid communication with the cooling air system and exhausting part of the portion of the air received from the cooling fan under pressure from the housing in the upward direction substantially in the plane of the rear wall of the housing.

13. The home cooking appliance of claim 12 , wherein the plurality of rear exhaust louvers are disposed on the rear wall of the housing.

14. The home cooking appliance of claim 13 , wherein the plurality of rear exhaust louvers are disposed in a central region across a width of the rear wall of the housing.

15. The home cooking appliance of claim 13 , wherein the plurality of rear exhaust louvers are arranged in a spaced manner across a width of the rear wall of the housing.

16. The home cooking appliance of claim 13 , wherein at least two of the plurality of rear exhaust louvers have one of different shapes and different sizes.

17. The home cooking appliance of claim 12 , wherein a higher concentration of the plurality of rear exhaust louvers are disposed at a central region with respect to a width of the housing.

18. The home cooking appliance of claim 12 , wherein a higher concentration of the plurality of rear exhaust louvers are disposed at an outer region with respect to a width of the housing.

19. The home cooking appliance of claim 12 , wherein the plurality of rear exhaust louvers are configured such that the pressurized air wash blowing in the upward direction has a higher pressure at a central region of the rear wall than at an outer region of the rear wall.

20. The home cooking appliance of claim 12 , wherein the plurality of rear exhaust louvers are distributed evenly across a width of the rear wall of the housing, the plurality of rear exhaust louvers configured such that the pressurized air wash blowing in the upward direction has a higher pressure at a central region of the rear wall than at an outer region of the rear wall.

21. The home cooking appliance of claim 12 , wherein the plurality of rear exhaust louvers are equally spaced across a width of the rear wall of the housing such that the pressurized air wash extends across the width of the rear wall of the housing, and
wherein at least one of a number, a size, or a shape of the rear exhaust louvers at each location across the width of the rear wall is configured such that the pressurized air wash blowing in the upward direction has a higher pressure at a central region of the rear wall than at an outer region of the rear wall.

22. The home cooking appliance of claim 12 , wherein the plurality of rear exhaust louvers includes:
a first horizontal row of louvers arranged in a spaced manner across a width of the rear wall of the housing such that the pressurized air wash extends across the width of the rear wall of the housing; and
at least a second horizontal row of louvers disposed in a central region of the rear wall and aligned in vertical rows with a group of louvers of the first horizontal row of louvers disposed in the central region of the rear wall such that the pressurized air wash has a higher pressure at the central region of the rear wall than at an outer region of the rear wall.

23. The home cooking appliance of claim 22 , wherein the first horizontal row of louvers is equally spaced across the width of the rear wall of the housing.

24. The home cooking appliance of claim 12 , wherein the plurality of rear exhaust louvers includes:
a first horizontal row of louvers arranged in a spaced manner across a width of the rear wall of the housing such that the pressurized air wash extends across the width of the rear wall of the housing; and
a plurality of second horizontal rows of louvers disposed in a central region of the rear wall and aligned in vertical rows with a group of louvers of the first horizontal row of louvers disposed in the central region of the rear wall such that the pressurized air wash has a higher pressure at the central region of the rear wall than at an outer region of the rear wall.

25. The home cooking appliance of claim 1 , wherein the cooking surface has an upper surface, and
wherein the rear vent trim has an upper surface that is substantially flush with the upper surface of the cooking surface, the rear vent trim including an opening permitting additional air to exit from the housing from the rear vent trim, and the rear vent trim directing the additional air away from a 90° angle with respect to the upper surface
