Abstract

A light-permeable hot plate includes at least one cavity filled with illuminant. The illuminant in the cavity can be excited to illuminate by an electromagnetic excitation field. The hot plate can be part of an induction hob, with the at least one cavity being arranged in a region of a cooking zone. The electromagnetic excitation field is provided to transfer energy into a household appliance which is arranged on the cooking zone.

Claims

1-15. -15. (canceled)

16. A light-permeable hot plate, said hot plate comprising at least one cavity filled with at least one illuminant which is excitable by an electromagnetic excitation field.

17. The hot plate of claim 16, configured in the form of a vitreous hot plate.

18. The hot plate of claim 16, configured in the form of a black glass-ceramic hot plate.

19. The hot plate of claim 16 for use with an induction hob.

20. The hot plate of claim 16, wherein the at least one cavity is arranged on a cooking zone of a hob.

21. The hot plate of claim 16, wherein the at least one cavity is arranged on a cooking zone of an induction hob.

22. The hot plate of claim 16, wherein the at least one cavity is formed at least partially in the hot plate.

23. The hot plate of claim 16, wherein the at least one cavity is formed completely in the hot plate.

24. The hot plate of claim 16, wherein the at least one cavity has an annular configuration.

25. The hot plate of claim 16, wherein the at least one cavity has at least one sector of annular configuration.

26. The hot plate of claim 16, wherein the at least one cavity is configured in the absence of an electrode introduced therein.

27. The hot plate of claim 16, further comprising at least one electrode introduced into the at least one cavity.

28. The hot plate of claim 16, wherein the at least one illuminant comprises a noble gas.

30. The induction hob of claim 28, wherein the at least one cavity is arranged in a region of a cooking zone, with the electromagnetic excitation field exciting the at least one illuminant to illuminate, said electromagnetic excitation field being provided to transfer energy into a household appliance which is arranged on the cooking zone.

32. The induction hob of claim 28, wherein the at least one cavity is disposed substantially at an outer edge of a cooking zone.

34. The method of claim 32, wherein the at least one cavity has been previously formed in the hot plate.

35. The method of claim 32, further comprising the steps of producing the cavity by forming a recess in an underside of the hot plate, and covering the recess.

29. An induction hob, comprising at least one hot plate having at least one cavity filled with at least one illuminant which is excitable by an electromagnetic excitation field.

31. The induction hob of claim 29, wherein the electromagnetic excitation field transfers energy into the household appliance in the form of a cooking utensil.

33. A method for producing a hot plate, comprising the steps of:

evacuating a cavity;

filling the cavity with at least one illuminant; and

sealing the cavity.
