Abstract

The door comprises at least one or more panels of thermal glass, on which thermochromic elements are applied, which are arranged close to one another, and which have respective activation temperature ranges, thus providing an easy-to-see indication of the temperatures in the oven.

Claims

1-11. -11. (canceled)

12. An oven appliance comprising:

a muffle defining a food cooking chamber; and

a door operably coupled with the muffle and moveable between open and closed positions, the door comprising;

at least one substantially transparent panel having a plurality of thermochromic elements arranged in close proximity to one another and having respective activation temperature ranges, so as to provide an indication about the temperatures inside the muffle.

13. The oven appliance of claim 12, wherein the thermochromic elements are arranged on an external portion of the door.

14. The oven appliance of claim 12, wherein the thermochromic elements are arranged on an internal portion of the door.

15. The oven appliance of claim 12, wherein the door includes a pair of opposing panels that define an interspace in which the thermochromic elements are arranged.

16. The oven appliance of claim 15, wherein the thermochromic elements are applied to the outermost panel of the door.

17. The oven appliance of claim 12, wherein the thermochromic elements are arranged according to a substantially linear geometry.

18. The oven appliance of claim 12, wherein the thermochromic elements are arranged according to a substantially circular geometry.

19. The oven appliance of claim 15, wherein the thermochromic elements are adhered to a panel of the door.

20. The oven appliance of claim 19, wherein the thermochromic elements are self-adhesive.

21. The oven appliance of claim 12, wherein the thermochromic elements have alphanumerical indicia visible within predefined temperature ranges, so as to provide indications about the temperature in the muffle.

22. The oven appliance of claim 12, wherein the thermochromic elements are active within different and contiguous respective temperature ranges, thus forming a continuous graduated scale.

23. An oven appliance comprising:

a muffle including a plurality of walls defining a food cooking chamber;

a plurality of controls disposed on a face of the muffle for controlling internal temperatures of the muffle; and

a door operably coupled with the muffle and moveable between open and closed positions, the door comprising;

at least one substantially transparent panel configured to allow viewing of the food cooking chamber;

a plurality of thermochromic elements arranged on the door, each of the plurality of thermochromic elements having a different activation temperature range, so as to provide an indication about the temperatures inside the muffle.

24. The oven appliance of claim 23, wherein the thermochromic elements are arranged on the substantially transparent panel of the door.

25. The oven appliance of claim 23, wherein the thermochromic elements are sensitive to respective temperature ranges of 2°

-3°

C.

26. The oven appliance of claim 23, wherein the door includes a pair of opposing panels that define an interspace in which the thermochromic elements are arranged.

27. The oven appliance of claim 26, wherein the thermochromic elements are applied to the outermost panel of the door.

28. The oven appliance of claim 23, wherein the thermochromic elements are arranged according to a substantially linear geometry.

29. The oven appliance of claim 23, wherein the thermochromic elements are arranged according to a substantially circular geometry.

30. The oven appliance of claim 26, wherein the thermochromic elements are adhered to a panel of the door.

31. The oven appliance of claim 23, wherein the thermochromic elements have alphanumerical indicia visible within predefined temperature ranges, so as to provide indications about the temperature in the muffle.
