Household appliance apparatus
View Patent ↗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.
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.
