Abstract

A cooking appliance having a cabinet including an insert within the cabinet to define cooking chamber with an access opening and a door selectively closing/opening the access opening, the cooking appliance comprising at least one of a first cooling flow path through a back wall of the cabinet, over a top wall of the insert, and out a side wall of the cabinet, a second cooling flow path through a bottom wall of the cabinet, along the bottom wall of the cabinet, and out a side wall of the cabinet, and a third cooling flow path through a bottom wall of the cabinet, out a front wall of the cabinet, into the door, out of the door, into a front wall of the cabinet, and out of a side wall of the cabinet.

First claim

The invention claimed is:

1. A method of cooling a cooking appliance having a cabinet including an insert within the cabinet to define a cooking chamber with an access opening and a door selectively closing/opening the access opening, the method comprising at least two of:
flowing cooling air through a back wall of the cabinet, over a top wall of the insert, and out a side wall of the cabinet to define a first cooling flow path;
flowing cooling air through a bottom wall of the cabinet, along the bottom wall of the cabinet, and out a side wall of the cabinet to define a second cooling flow path; and
flowing cooling air through a bottom wall of the cabinet, out a front wall of the cabinet, into the door, out of the door, into a front wall of the cabinet, and out of a side wall of the cabinet to define a third cooling flow path.

2. The method of claim 1 wherein the at least two of the first cooling flow path, the second cooling flow path, and the third cooling flow paths are fluidly isolated from each other.

3. The method of claim 1 wherein the first and second cooling flow paths flow out different side walls of the cabinet.

4. The method of claim 1 wherein the first and second cooling flow paths flow out a common vent in a same side wall.

5. The method of claim 1 wherein the first cooling flow path flows over a sensor assembly.

6. The method of claim 1 wherein the second cooling flow path flows over a controller.

7. The method of claim 1 wherein the third cooling flow path flows over a human machine interface (HMI).

8. The method of claim 7 wherein the HMI is located in the door.

9. A cooking appliance having a cabinet including an insert within the cabinet to define a cooking chamber with an access opening and a door selectively closing/opening the access opening, the cooking appliance comprising at least two of:
a first cooling flow path through a back wall of the cabinet, over a top wall of the insert, and out a side wall of the cabinet;
a second cooling flow path through a bottom wall of the cabinet, along the bottom wall of the cabinet, and out a side wall of the cabinet; and
a third cooling flow path through a bottom wall of the cabinet, out a front wall of the cabinet, into the door, out of the door, into a front wall of the cabinet, and out of a side wall of the cabinet.

10. The cooking appliance of claim 9 wherein the first, second, and third cooling flow paths are fluidly isolated from each other.

11. The cooking appliance of claim 9 wherein the first and second cooling flow paths flow out different side walls of the cabinet.

12. The cooking appliance of claim 9 wherein the first and second cooling flow paths flow out a common vent in a same side wall.

13. The cooking appliance of claim 9 wherein the first cooling flow path flows over a sensor assembly.

14. The cooking appliance of claim 9 wherein the second cooling flow path flows over a controller.

15. The cooking appliance of claim 9 wherein the third cooling flow path flows over a human machine interface (HMI).

16. The cooking appliance of claim 15 wherein the HMI is located in the door.

17. The cooking appliance of claim 9 , further comprising at least one fan for generating an air flow flowing through each of the at least two of the first cooling flow path, the second cooling flow path, and the third cooling flow path.

18. The cooking appliance of claim 9 further comprising at least one deflector defining the at least two of the first cooling flow path, the second cooling flow path, and the third cooling flow path.

19. The method of claim 1 , wherein the method comprises flowing cooling air through each of the first cooling flow path, the second cooling flow path, and the third cooling flow path.
