Abstract

A cooking appliance includes a cooking chamber with cooking chamber wall, a microwave heat source configured to heat food, and a support device configured to hold a food-supporting member. The cooking chamber wall includes an opening and a lead-through device, and the lead-through device includes a through-hole configured to receive a fastening element of the support device. A tubular guide portion is formed at the through-hole of the lead-through device, and the tubular guide portion includes a safety portion configured to shield against microwave radiation and such that no part of the fastening element is located within the safety portion when the fastening element is in an installed condition in the lead-through device.

First claim

What is claimed is:

1 . A cooking appliance, comprising:
at least one cooking chamber, comprising:
at least one cooking chamber wall;
at least one microwave heat source configured to heat food; and
at least one support device configured to hold at least one food-supporting member,
wherein the at least one cooking chamber wall includes at least one opening and at least one lead-through device, the at least one lead-through device including at least one through-hole configured to receive at least one fastening element of the at least one support device, and wherein at least one tubular guide portion is formed at the at least one through-hole of the at least one lead-through device, the at least one tubular guide portion including at least one safety portion configured to shield against microwave radiation and configured such that no part of the at least one fastening element is located within the at least one safety portion when the at least one fastening element is in an installed condition in the at least one lead-through device.

2 . The cooking appliance of claim 1 , wherein a length of the at least one tubular guide portion is longer than a portion of the at least one fastening element received in the at least one through-hole when the at least one fastening element is in the installed condition.

3 . The cooking appliance of claim 1 , wherein a diameter of the at least one through-hole is smaller than half of a wavelength of the microwave radiation produced by the at least one microwave heat source.

4 . The cooking appliance of claim 1 , wherein a length of the at least one tubular guide portion is greater than a thickness of the at least one cooking chamber wall in a region of the at least one opening.

5 . The cooking appliance of claim 1 , wherein the at least one lead-through device is at least partially configured as a hollow rivet.

6 . The cooking appliance of claim 1 , further comprising at least one isolation device configured to electrically isolate the at least one support device from the at least one cooking chamber wall.

7 . The cooking appliance of claim 6 , wherein the at least one isolation device includes at least one spacing device configured to prevent the at least one fastening element from being inserted into the at least one safety portion.

8 . The cooking appliance of claim 6 , further comprising at least one steam generator device configured to heat and evaporate water using a heating device, and wherein the at least one isolation device includes at least one blind hole configured to receive at least a portion of the at least one fastening element.

9 . The cooking appliance of claim 6 , wherein the at least one isolation device includes at least one mounting aid.

10 . The cooking appliance of claim 6 , wherein at least a portion of the at least one isolation device overlaps at least a portion of the at least one lead-through device and at least a portion of the at least one cooking chamber wall.

11 . The cooking appliance of claim 6 , wherein the at least one isolation device has an oversized diameter with respect to the at least one through-hole.

12 . The cooking appliance of claim 6 , wherein the at least one isolation device includes at least one fastening device configured to be attached to the at least one lead-through device.

13 . A fastening system for a cooking appliance that includes at least one cooking chamber having at least one cooking chamber wall with at least one opening therein, at least one microwave heat source configured to heat food, and at least one support device configured to hold at least one food-supporting member, the fastening system comprising:
at least one lead-through device configured to be provided on the at least one cooking chamber wall of the cooking appliance, the at least one lead-through device including at least one through-hole configured to receive at least one fastening element of the at least one support device, wherein at least one tubular guide portion is formed at the at least one through-hole of the lead-through device, the at least one tubular guide portion including at least one safety portion configured to shield against microwave radiation and configured such that no part of the at least one fastening element is located within the at least one safety portion when the at least one fastening element is in an installed condition in the at least one lead-through device.
