Abstract

Bekannt ist eine Kochplatte mit einer Keramikplatte, deren Oberseite als Abstellfläche für ein zu beheizendes Garbehältnis dient und an deren Unterseite eine elektrisch isolierende Isolatorschicht angeordnet ist, deren Unterseite ein elektrisches Heizelement zugeordnet ist. Um mit einfachen Mitteln die elektrische Sicherheit der Kochplatte gewährleisten zu können, besteht die Keramikplatte aus thermisch und elektrisch leitfähigem Material, wobei die Keramikplatte geerdet ist.

Known is a hotplate with a ceramic plate, the top of which serves as a storage surface for a cooking container to be heated and on the underside of which an electrically insulating insulator layer is arranged, the underside of which is associated with an electric heating element. In order to be able to ensure the electrical safety of the hotplate with simple means, the ceramic plate consists of thermally and electrically conductive material, the ceramic plate being earthed.
