Abstract

A cover plate for a domestic appliance includes an at least semi-transparent support plate having a bottom provided with at least one colored layer and at least one semi-transparent metal layer. The metal layer has at least one continuous cut-out section and the colored layer is arranged in the area of the cut-out section.

First claim

The invention claimed is:

1. A domestic appliance cover plate, comprising:
an at least semi-transparent support plate having a bottom provided with at least one colored layer and at least one semi-transparent or opaque metallic layer,
wherein the metallic layer has at least one continuous cut-out section, said colored layer being provided in a region of the cut-out section;
the domestic appliance further comprising a light source disposed beneath the colored layer, said colored layer having at least one continuous cut-out section for passage of light from the light source;
wherein the metallic layer is configured to extend above the colored layer without a cut-out section over an entire surface of the cut-out section in the colored layer.

2. The domestic appliance cover plate of claim 1 , wherein the colored layer is formed beneath the metallic layer.

3. The domestic appliance cover plate of claim 1 , wherein the metallic layer is applied using a sputter procedure.

4. The domestic appliance cover plate of claim 1 , wherein the cut-out section in the metallic layer is produced by laser processing.

5. The domestic appliance cover plate of claim 1 , wherein the colored layer is configured as a visual information display layer and as a scratch protection layer for the metallic layer.

6. The domestic appliance cover plate of claim 1 , wherein the cut-out section in the metallic layer is configured without any overlap with the cut-out section in the colored layer.

7. A domestic appliance for preparing food, said domestic appliance comprising:
a domestic appliance cover plate which includes an at least semi-transparent support plate having a bottom provided with at least one colored layer; and
at least one semi-transparent or opaque metallic layer,
wherein the metallic layer has at least one continuous cut-out section, said colored layer being provided in a region of the cut-out section;
the domestic appliance further comprising a light source disposed beneath the colored layer, said colored layer having at least one continuous cut-out section for passage of light from the light source;
wherein the metallic layer is configured to extend above the colored layer without a cut-out section over an entire surface of the cut-out section in the colored layer.

8. The domestic appliance of claim 7 , constructed in the form of a hob.

9. The domestic appliance of claim 7 , wherein the colored layer is formed beneath the metallic layer.

10. The domestic appliance of claim 7 , wherein the metallic layer is applied using a sputter procedure.

11. The domestic appliance of claim 7 , wherein the cut-out section in the metallic layer is produced by laser processing.

12. The domestic appliance of claim 7 , wherein the colored layer is configured as a visual information display layer and as a scratch protection layer for the metallic layer.

13. The domestic appliance of claim 7 , wherein the cut-out section in the metallic layer is configured without any overlap with the cut-out section in the colored layer.

14. A method for producing a domestic appliance cover plate, comprising:
applying at least one semi-transparent or opaque metallic layer on a bottom of an at least semi-transparent support plate;
forming at least one continuous cut-out section in the metallic layer; and
applying a colored layer beneath the metallic layer at least in a region of the cut-out section;
wherein the cut-out section in the colored layer is configured so as to be completely covered by the metallic layer; and
wherein the cut-out section in the colored layer is configured without any overlap with the cut-out section in the metallic layer.

15. The method of claim 14 , wherein the metallic layer is applied using a sputter procedure and the cut-out section is produced by laser processing.

16. The method of claim 14 , further comprising forming at least one continuous cut-out section in the colored layer for passage of light from a light source disposed beneath the colored layer.
