Abstract

A home cooking appliance includes a housing, a cooking compartment in the housing and accessible through a door in the housing, a cooling air system conveying air through the housing, and an air channel in fluid communication with the cooling air system, the air channel having an outlet exhausting a portion of the air from the cooling air system along a rear wall of the housing.

First claim

What is claimed is:

1. A home cooking appliance comprising:
a housing;
a cooking compartment in the housing and accessible through a door in the housing;
a cooling air system having a cooling fan that conveys ambient kitchen air into and through the housing between the cooking compartment and the housing to cool components of the home cooking appliance;
an air channel in fluid communication with the cooling air system, the air channel having an inlet that receives a first portion of air from the ambient kitchen air from the cooling fan of the cooling air system and an outlet that exhausts the first portion of the air from the cooling air system along a rear wall of the housing; and
a rear vent trim on a top of the housing and in fluid communication with the cooling air system, the rear vent trim including an opening permitting a second portion of air from the ambient kitchen air from the cooling fan of the cooling air system to exit from the top of the housing,
wherein the cooling air system is configured to divide and separate the air into the first portion and the second portion, to divert the first portion of the air into the air channel to be exhausted from the outlet along the rear wall of the housing into a first exterior area behind the housing, and to divert the second portion of the air to the rear vent trim to be exhausted from the opening of the rear vent trim into a second exterior area above the housing, to thereby increase an amount of the air flowing through the cooling air system while minimizing cooling fan noise,
wherein the outlet of the air channel directs the first portion of the air from the outlet in a direction along an exterior surface of the rear wall of the housing and parallel to the exterior surface of the rear wall of the housing, and
wherein the air channel extends at a first angle other than a vertical direction and a horizontal direction and conveys the first portion of the air from the inlet of the air channel to the outlet of the air channel at the first angle other than the vertical direction and the horizontal direction.

2. The home cooking appliance of claim 1 , wherein the outlet of the air channel directs the first portion of the air from the outlet in a downward direction along the exterior surface of the rear wall of the housing.

3. The home cooking appliance of claim 2 , wherein the downward direction is a vertical downward direction.

4. The home cooking appliance of claim 2 , wherein the downward direction is a direction extending at an angle other than a vertical direction.

5. The home cooking appliance of claim 1 , wherein the outlet of the air channel includes a deflector that directs the first portion of the air from the outlet in the direction along the exterior surface of the rear wall of the housing.

6. The home cooking appliance of claim 5 , wherein the direction is a vertical direction.

7. The home cooking appliance of claim 5 , wherein the direction extends at an angle other than a vertical direction.

8. The home cooking appliance of claim 1 , wherein the air channel is on the exterior surface of the rear wall of the housing.

9. The home cooking appliance of claim 1 , wherein the air channel extends in a direction along the rear wall of the housing.

10. The home cooking appliance of claim 1 , wherein the air channel includes an inlet and an outlet,
wherein the inlet is in fluid communication with the cooling air system and the outlet is open to an exterior of the appliance,
wherein the outlet is arranged closer to a bottom of the rear wall of the appliance than the inlet.

11. The home cooking appliance of claim 10 , wherein the air channel comprises a wall cooperating with the rear wall of the appliance to form a flow path between the inlet and the outlet.

12. The home cooking appliance of claim 10 , wherein the air channel comprises at least three walls cooperating with the rear wall of the appliance to form a flow path between the inlet and the outlet.

13. The home cooking appliance of claim 1 , further comprising:
a cooking surface on the top of the housing,
wherein the rear vent trim has an upper surface that is substantially flush with an upper surface of the cooking surface.

14. The home cooking appliance of claim 13 , wherein the rear vent trim directs the second portion of the air forward and away from a 90° angle with respect to the upper surface of the cooking surface.

15. The home cooking appliance of claim 1 , wherein the portion of the air exhausted from the air channel along the rear wall of the housing is greater than the second portion of the air exhausted from the opening of the rear vent trim on the top of the housing.

16. The home cooking appliance of claim 1 , wherein the portion of the air exhausted from the air channel along the rear wall of the housing is less than the second portion of the air exhausted from the opening of the rear vent trim on the top of the housing.

17. The home cooking appliance of claim 1 , wherein the portion of the air exhausted from the air channel along the rear wall of the housing is substantially equal to the second portion of the air exhausted from the opening of the rear vent trim on the top of the housing.

18. A home cooking appliance comprising:
a housing;
a cooking compartment in the housing and accessible through a door in the housing;
a cooling air system having a cooling fan conveying ambient kitchen air into and through the housing between the cooking compartment and the housing to cool components of the home cooking appliance;
a first exhaust outlet in fluid communication with the cooling fan of the cooling air system and exhausting a first portion of air from the ambient kitchen air from the cooling fan of the cooling air system into a first exterior area above the housing; and
an air channel in fluid communication with the cooling fan of the cooling air system, the air channel having a second exhaust outlet exhausting a second portion of air from the ambient kitchen air from the cooling fan of the cooling air system into a second exterior area at a rear wall of the housing,
wherein the cooling air system is configured to divide and separate the air into the first portion and the second portion, to divert the first portion of the air to the first exhaust outlet to be exhausted from the first exhaust outlet into the first exterior area above the housing, and to divert the second portion of the air to the air channel to be exhausted from the second exhaust outlet into the second exterior area along the rear wall of the housing, to increase air flow through the cooling air system while minimizing cooling fan noise,
wherein the second exhaust outlet of the air channel directs the second portion of the air from the second exhaust outlet in a direction along an exterior surface of the rear wall of the housing and parallel to the exterior surface of the rear wall of the housing, and
wherein the air channel extends at a first angle other than a vertical direction and a horizontal direction and conveys the second portion of the air to the second exhaust outlet at the first angle other than the vertical direction and the horizontal direction.

19. The home cooking appliance of claim 18 , wherein the first exhaust outlet is on a top of the housing and exhausts the first portion of the air from the cooling air system into the first exterior area above the housing.

20. The home cooking appliance of claim 19 , wherein the first portion of the air exhausted from the first exhaust outlet on the top of th
