Abstract

The present invention relates to an induction cooking hob with illuminating equipment. The induction cooking hob includes a panel ( 10 ) arranged at the top side of said induction cooking hob, and a chassis ( 12 ) forming a substructure of said induction cooking hob. The panel ( 10 ) comprises at least one heating zone ( 14 ). The chassis ( 12 ) comprises at least one induction coil ( 16 ). The heating zone ( 14 ) corresponds with at least one induction coil ( 16 ). The induction cooking hob includes at least one intermediate layer ( 18, 20 ) between the panel ( 10 ) and the chassis ( 12 ). The intermediate layer ( 18 ) comprises a plurality of cut-outs ( 22 ) arranged according to a predetermined pattern within the heating zone ( 14 ). The chassis ( 12 ) comprises at least one light emitting diode ( 24 ) arranged in a central portion of the induction coil ( 16 ).

First claim

The invention claimed is:

1. An induction cooking hob with illumination equipment, comprising:
a panel ( 10 ) arranged at the top side of said induction cooking hob and comprising at least one heating zone ( 14 ),
a chassis ( 12 ) forming a substructure of said induction cooking hob, said chassis ( 12 ) comprising at least one induction coil ( 16 ) corresponding with the at least one heating zone and at least one light emitting diode ( 24 ) arranged in a central portion of the at least one induction coil ( 16 ),
at least one intermediate layer ( 18 , 20 ) between the panel ( 10 ) and the chassis ( 12 ), said intermediate layer ( 18 , 20 ) comprising a plurality of cut-outs ( 22 ) arranged according to a predetermined pattern within the at least one heating zone ( 14 ),
wherein at least one light emitting diode ( 24 ) corresponds with at least one cut-out ( 22 ),
wherein light from the at least one light emitting diode ( 24 ) propagates through at least one of the cut-outs ( 22 ) arranged within the at least one heating zone ( 14 ) and through the panel ( 10 ) illuminating the at least one heating zone ( 14 ) in which the at least one light emitting diode ( 24 ) is arranged, and
wherein the light emitting diode ( 24 ) is fastened at the chassis ( 12 ) by an elongated support element ( 26 ), which is also used to support a temperature sensor and which functions as an optical device and guides the light to the cut-outs ( 22 ).

2. The induction cooking hob according to claim 1 , wherein the intermediate layer ( 18 , 20 ) includes a non-transparent printed layer ( 18 ) applied at a lower side of the panel ( 10 ) and the non-transparent printed layer ( 18 ) allows the light from the at least one light emitting diode ( 24 ) to propagate through at least one of the cut-outs ( 22 ).

3. The induction cooking hob according to claim 2 , wherein the printed layer ( 18 ) is a black colored layer.

4. The induction cooking hob according to claim 2 , wherein the cut-outs ( 22 ) are formed as blank portions of the printed layer ( 18 ).

5. The induction cooking hob according to claim 1 , wherein the intermediate layer ( 18 , 20 ) includes a non-transparent sheet ( 20 ) arranged between the panel ( 10 ) and the chassis ( 12 ) and the non-transparent sheet ( 20 ) allows the light from the at least one light emitting diode ( 24 ) to propagate through at least one of the cut-outs ( 22 ).

6. The induction cooking hob according to claim 5 , wherein the sheet ( 20 ) is made of at least one dielectric material.

7. The induction cooking hob according to claim 6 , wherein the sheet ( 20 ) is or comprises a mica layer.

8. The induction cooking hob according to claim 1 , wherein the cut-outs ( 22 ) in the layer ( 18 , 20 ) are filled by a transparent dielectric material.

9. The induction cooking hob according to claim 1 , wherein the cut-outs ( 22 ) in the intermediate layer ( 18 , 20 ) are filled by a foil made of polyimide.

10. The induction cooking hob according to claim 1 , wherein the support element ( 26 ) is made of a thermally insulating material, said support element ( 26 ) extending horizontally within or below the central portion of the at least one induction coil ( 16 ).

11. The induction cooking hob according to claim 1 , wherein the cut-outs ( 22 ) are shaped as slots arranged according to a predetermined pattern.

12. The induction cooking hob according to claim 1 , wherein the panel ( 10 ) is a glass ceramic panel ( 10 ).

13. The induction cooking hob according to claim 1 , wherein the plurality of cut-outs ( 22 ), when viewed from a direction perpendicular to the panel ( 10 ), surround the at least one light emitting diode ( 24 ).

14. The induction cooking hob according to claim 1 , wherein each of the plurality of cut-outs ( 22 ) extends radially from the central portion of the at least one induction coil ( 16 ) within which the at least one light emitting diode ( 24 ) is arranged toward a periphery of the at least one induction coil ( 16 ).

15. The induction cooking hob according to claim 1 , wherein a length of each of the plurality of cut-outs ( 22 ) arranged within the at least one heating zone ( 14 ) indicates a size of the at least one heating zone ( 14 ).
