Abstract

Moderne Kochfelder besitzen eine Glaskeramikplatte (1) als Kochfläche, die mindestens eine Kochzone aufweist, der typischerweise ein Strahlungsheizkörper zugeordnet ist. Zur Anzeige der Kochzone und ggf. zur Restwärmeanzeige ist es bekannt, dem Heizkörper einen fremd beleuchteten Glasring zuzuordnen, der von oben als Lichtring optisch wahrnehmbar ist. Durch Aufbringen einer Maske auf den Glasring kann auch eine strukturiert beleuchtete Kochzonenanzeige erzielt werden. Die Herstellung der Maske ist teuer. Ferner ist die Handhabung bei der Montage des Kochfeldes aufwendig.Modern hobs have a glass ceramic plate (1) as the cooking surface has at least one cooking zone, typically a Radiant heater is assigned. To display the cooking zone and if necessary Residual heat indicator, it is known that the radiator is externally illuminated Allocate a glass ring that is visible from above as a light ring. By applying a mask to the glass ring you can also structure one illuminated cooking zone display can be achieved. The mask is made expensive. Furthermore, the handling during assembly of the hob is complex.

Die Erfindung sieht vor, daß auf der Unterseite der Glaskeramikplatte (1) direkt eine lichtundurchlässige Deckschicht (2) mit entsprechend der gewünschten Struktur innerhalb der Kochzonenanzeige transparenten Bereichen aufgebracht ist.The invention provides that on the underside of the glass ceramic plate (1) directly an opaque cover layer (2) with the corresponding desired structure within the cooking zone display transparent areas is applied.

Dieses Aufbringen erfolgt vorzugsweise durch Aufdrucken eines temperaturbeständigen lichtundurchlässigen Lackes mittels Siebdruck.
