Abstract

A divider assembly is provided for dividing a cooking cavity of a microwave oven into two cooking subcavities. The divider assembly includes a first tempered glass panel, a metal frame extending around the periphery of the first tempered glass panel to support the first tempered glass panel, a honeycomb core positioned above the first tempered glass panel, a second tempered glass panel positioned above the honeycomb core, and a gasket extending around the periphery of the metal frame for engaging metal walls of the microwave oven, wherein the gasket includes small-diameter, long-length carbon nano-tubes.

Claims (39)

1. A divider assembly for dividing a cooking cavity of a microwave oven into two cooking subcavities, the divider assembly comprising:

a first tempered glass panel;

a metal frame extending around the periphery of the first tempered glass panel to support the first tempered glass panel;

a honeycomb core positioned above the first tempered glass panel;

a second tempered glass panel positioned above the honeycomb core; and

a gasket extending around the periphery of the metal frame for engaging metal walls of the microwave oven, wherein the gasket comprises small-diameter, long-length carbon nano-tubes.

2. The divider assembly of claim 1 , wherein the gasket is electrically conductive so as to electrically couple the metal frame to the metal walls of the microwave oven.

3. The divider assembly of claim 1 , wherein the gasket comprises a high temperature silicon tube around which the small-diameter, long-length carbon nano-tubes are formed.

4. The divider assembly of claim 1 , wherein the small-diameter, long-length carbon nano-tubes are single-walled carbon nano-tubes.

5. The divider assembly of claim 1 , wherein the small-diameter, long-length carbon nano-tubes are multi-walled carbon nano-tubes.

6. The divider assembly of claim 1 , wherein the small-diameter, long-length carbon nano-tubes are formed from a hexagonal lattice of carbon atoms.

7. The divider assembly of claim 6 , wherein the hexagonal lattice of carbon atoms is capped by fullerene-like structures.

8. The divider assembly of claim 1 , and further comprising at least one foot extending downward from a surface of the metal frame for engaging at least one shelf ledge that extends from the inner walls of the microwave oven.

9. The divider assembly of claim 1 , and further comprising a tin-oxide coating on a surface of one of the first and second tempered glass panels.

10. The divider assembly of claim 9 , wherein the tin-oxide coating is disposed on a surface of the second tempered glass panel.

11. An electromagnetic cooking device comprising:

an enclosed cavity;

the divider assembly of claim 1 disposed within the enclosed cavity so as to divide the enclosed cavity into a first subcavity and a second subcavity;

at least one first microwave source for generating microwave energy within the first subcavity to cook food disposed therein; and

at least one second microwave source for generating microwave energy within the second subcavity to cook food disposed therein.

12. A microwave oven comprising:

an enclosed cavity;

a divider assembly disposed within the enclosed cavity so as to divide the enclosed cavity into a first subcavity and a second subcavity;

at least one first microwave source for generating microwave energy within the first subcavity to cook food disposed therein; and

at least one second microwave source for generating microwave energy within the second subcavity to cook food disposed therein,

wherein the divider assembly comprises:

a first tempered glass panel;

a metal frame extending around the periphery of the first tempered glass panel to support the first tempered glass panel;

a honeycomb core positioned above the first tempered glass panel;

a second tempered glass panel positioned above the honeycomb core; and

a gasket extending around the periphery of the metal frame for engaging metal walls of the microwave oven, wherein the gasket comprises small-diameter, long-length carbon nano-tubes.

13. The microwave oven of claim 12 , wherein the gasket is electrically conductive so as to electrically couple the metal frame to the metal walls of the microwave oven.

14. The microwave oven of claim 12 , wherein the gasket comprises a high temperature silicon tube around which the small-diameter, long-length carbon nano-tubes are formed.

15. The microwave oven of claim 12 , wherein the small-diameter, long-length carbon nano-tubes are single-walled carbon nano-tubes.

16. The microwave oven of claim 12 , wherein the small-diameter, long-length carbon nano-tubes are multi-walled carbon nano-tubes.

17. The microwave oven of claim 12 , and further comprising at least one foot extending downward from a surface of the metal frame for engaging at least one shelf ledge that extends from the inner walls of the microwave oven.

18. The microwave oven of claim 12 , and further comprising a tin-oxide coating on a surface of one of the first and second tempered glass panels.

19. The microwave oven of any one of claim 18 , wherein the tin-oxide coating is disposed on a surface of the second tempered glass panel.

20. The microwave oven of claim 12 , wherein the at least one first microwave source includes two solid-state microwave sources and the at least one second microwave source includes two solid-state microwave sources.
