Abstract

A cooktop apparatus, in particular an induction cooktop apparatus, includes at least one glass unit and at least one coating configured as a multilayer structure, which is disposed on at least one subregion of at least a main face of the glass unit and has at least two layers. In order to achieve optimum compatibility with the sensors of the user interface without requiring a process after deposition, at least one of the layers is formed by at least one semiconducting material, to fulfill the function of an absorbing layer.

Claims (33)

1. A cooktop apparatus, comprising:

a glass unit;

a touch-sensitive sensor that senses a touch by a user of the cooktop to control a function of the cooktop; and

a coating configured as a multilayer structure and disposed on at least one subregion of a main face of the glass unit between the glass unit and the touch-sensitive sensor, said coating having

a first layer formed by a semiconducting material;

a second layer formed by a semiconducting material; and

an insulating layer which is formed of electrically insulating material and disposed between the first layer and the second layer.

2. The cooktop apparatus of claim 1 , constructed in the form of an induction cooktop apparatus.

3. The cooktop apparatus of claim 1 , wherein the glass unit is designed as a cooktop plate unit.

4. The cooktop apparatus of claim 1 , wherein the coating has a transparency of maximum 20%.

5. The cooktop apparatus of claim 1 , wherein the coating has a thickness of maximum 10 μm.

6. The cooktop apparatus of claim 1 , wherein the coating is configured to produce a metallic appearance.

7. The cooktop apparatus of claim 1 , further comprising at least one electronic unit configured to measure and evaluate at least one electrical characteristic of the first layer.

8. The cooktop apparatus of claim 1 , further comprising a protective coating positioned on the multilayer coating, wherein the touch-sensitive sensor is positioned on the protective coating.

9. The cooktop apparatus of claim 1 , further comprising a protective coating, wherein the touch-sensitive sensor is positioned between the multilayer coating and the protective coating.

10. The cooktop apparatus of claim 7 , wherein the electronic unit is configured to detect at least one safety parameter.

11. A cooktop, comprising:

at least one cooktop apparatus including

a glass unit,

a touch-sensitive sensor that senses a touch by a user of the cooktop to control a function of the cooktop, and

a coating configured as a multilayer structure and disposed on at least one subregion of a main face of the glass unit between the glass unit and the touch-sensitive sensor, said coating having

a first layer formed by a semiconducting material;

a second layer formed by a semiconducting material; and

an insulating layer which is formed of electrically insulating material and disposed between the first layer and the second layer.

12. The cooktop of claim 11 , constructed in the form of an induction cooktop.

13. The cooktop of claim 11 , wherein the glass unit is designed as a cooktop plate unit.

14. The cooktop of claim 11 , wherein the coating has a transparency of maximum 20%.

15. The cooktop of claim 11 , wherein the coating has a thickness of maximum 10 μm.

16. The cooktop of claim 11 , wherein the coating is configured to produce a metallic appearance.

17. The cooktop of claim 11 , wherein the cooktop apparatus includes at least one electronic unit configured to measure and evaluate at least one electrical characteristic of the first layer.

18. The cooktop of claim 11 , further comprising a protective coating positioned on the multilayer coating, wherein the touch-sensitive sensor is positioned on the protective coating.

19. The cooktop of claim 11 , further comprising a protective coating, wherein the touch-sensitive sensor is positioned between the multilayer coating and the protective coating.

20. The cooktop of claim 17 , wherein the electronic unit is configured to detect at least one safety parameter.
