Hob and method for producing a hob
View Patent ↗A hob includes a cooking surface with a glass ceramic defining a cutout in an outside edge of the glass ceramic, and an insert in the cutout including a material that is different from the glass ceramic and which is permeable to light in a blue spectral range.
1. A hob comprising:
a cooking surface comprising a glass ceramic and defining a cutout in an outside edge of the glass ceramic; and
an insert in the cutout comprising a material that is different from the glass ceramic and which is permeable to light in a blue spectral range, wherein an outside edge of the insert is partially bordered by the outside edge of the glass ceramic.
2. The hob of claim 1 , wherein a front edge of the insert is flush with a front edge of the glass ceramic.
3. The hob of claim 1 , wherein the insert comprises gray glass.
4. The hob of claim 1 , further comprising a symbol or a scale on a rear side of the insert.
5. The hob of claim 1 , further comprising a centering element on a rear side of the insert for positioning of a display or a light source.
6. The hob of claim 1 , wherein the insert is trapezoid shaped.
7. The hob of claim 1 , wherein the insert is glued into the cutout.
8. The hob of claim 7 , wherein the insert is attached with different adhesives in the cutout.
9. The hob of claim 7 , wherein the insert is attached with a UV adhesive and a silicon adhesive in the cutout.
10. The hob of claim 8 , wherein the insert and the glass ceramic in the cutout defines a gap that includes dots of the UV adhesive and a contiguous bead of the silicon adhesive.
11. The hob of claim 1 , wherein the insert and the glass ceramic in the cutout defines a gap with a width of between 2 mm and 6 mm.
12. The hob of claim 11 , wherein the gap has a width of about 4 mm.
13. The hob of claim 1 , further comprising a decorative frame covering a top of a gap defined by the insert and the glass ceramic in the cutout.
14. The hob of claim 13 , wherein the decorative frame has a width of between 10 mm and 20 mm.
15. The hob of claim 14 , wherein the decorative frame has a width of about 15 mm.
16. The hob of claim 13 , wherein the decorative frame has a height of between 0.5 mm and 1 mm.
17. The hob of claim 16 , wherein the decorative frame has a height of 0.7 mm.
18. The hob of claim 1 , wherein the insert has a coating that is permeable to light in the blue spectral range.
19. The hob of claim 18 , wherein the coating is on a rear side of the insert.
20. The hob of claim 18 , wherein the coating comprises a film.
21. The hob of claim 18 , wherein the coating comprises an imprint.
22. A method for producing a hob comprising:
cutting out one edge of a glass ceramic of a cooking surface to form an edge cutout;
inserting the glass ceramic into a decorative frame;
inserting an insert that comprises a material that differs from a material of the glass ceramic and that is permeable to light in a blue spectral range into the edge cutout; and
joining the insert to the glass ceramic with two different adhesives.
23. The method of claim 22 , wherein a rear side to the decorative frame points upwards, and wherein inserting the glass ceramic into the decorative frame comprises inserting the glass ceramic into the decorative frame with a rear side of the glass ceramic pointing upwards and wherein inserting the insert comprises inserting the insert with a rear side of the insert pointing upwards.
24. The method of claim 22 , further comprising providing an adhesive in a gap between the insert and the glass ceramic and wherein the decorative frame covers the gap.
25. The method of claim 22 , wherein the joining of the insert to the glass ceramic comprises introducing dots of UV adhesive into a gap between the insert and the glass ceramic.
26. The method of claim 25 , further comprising inserting a silicon adhesive into the gap as a contiguous bead after the UV adhesive has hardened.
27. A hob comprising:
a cooking surface comprising a glass ceramic and defining a cutout in an outside edge of the glass ceramic; and
an insert in the cutout comprising a material that is different from the glass ceramic and which is permeable to light in a blue spectral range, and
a centering element on a rear side of the insert for positioning of a display or a light source wherein the centering element includes a projecting member on a rear side of the insert for operational contact with an underlying structure.
28. The hob of claim 27 , wherein the centering element is a conical member projecting from a rear side of the insert.
29. A hob comprising:
a cooking surface comprising a glass ceramic and defining a cutout in an outside edge of the glass ceramic; and
an insert in the cutout comprising a material that is different from the glass ceramic and which is permeable to light in a blue spectral range, wherein the insert is attached with different adhesives in the cutout.
