Abstract

A seal arrangement for a cooking apparatus, the seal arrangement comprising: a cooking cavity wall with an opening configured to be sealed by the seal arrangement and configured as a pass through for an illuminant configured as a translucent rod with an essentially circular cylindrical shape; a housing element that is sealed relative to an outside of the cooking cavity wall by a first seal and that includes a receiver for a second seal that seals the housing element relative to the illuminant; retaining elements which arrange the housing element at the outside of the cooking cavity wall, wherein the second seal is a graphite ring, and wherein the illuminant is arrangeable within an annular cavity of the graphite ring.

First claim

What is claimed is:

1 . A seal arrangement for a cooking apparatus, the seal arrangement comprising:
a cooking cavity wall with an opening configured to be sealed by the seal arrangement and configured as a pass through for an illuminant configured as a translucent rod with an essentially circular cylindrical shape; a housing element that is sealed relative to an outside of the cooking cavity wall by a first seal and that includes a receiver for a second seal that seals the housing element relative to the illuminant; retaining elements which arrange the housing element at the outside of the cooking cavity wall, wherein the second seal is a graphite ring, and wherein the illuminant is arrangeable within an annular cavity of the graphite ring.

2 . The seal arrangement according to claim 1 , wherein graphite ring is cut along a cut line.

3 . The seal arrangement according to claim 2 ,
wherein the cut line is oriented at an angle greater than 0° and up 45° to relative to a radial line of the seal ring.

4 . The seal arrangement according to claim 1 , wherein the seal ring is fabricated with under size, over size or identical size relative to a circumferential contour of the illuminant that is arrangeable within the seal ring.

5 . The seal arrangement according to claim 1 , wherein a thermal expansion coefficient of the seal ring is substantially identical to a thermal expansion coefficient of the illuminant or greater than the thermal expansion coefficient of the illuminant.
