Cooking hob device, has thermo-chromic and/or thermo-luminescent element provided to view part of hoisting area outline, and upper view unit provided free from cool zone marks in operational condition

The device has a thermo-chromic and/or thermo-luminescent element (10) provided to view a part of a hoisting area outline. An upper view unit is provided to be free from cool zone marks in an operational condition, and a structural element (18) includes a side formed as a mess kit main beam surface (16) for setting up mess kit elements and includes a large part of a mess kit heating zone (24). The thermo-chromic and/or thermo-luminescent element extends over the part of the mess kit heating zone and includes vanadium-containing material with vanadium dioxide. An independent claim is also included for a method for manufacturing a cooking hob device. Um eine effektive Bauweise zu erreichen, wird eine Kochfeldvorrichtung mit wenigstens einem thermochromen und/oder thermolumineszenten Element (10) vorgeschlagen, welches dazu vorgesehen ist, zumindest einen Teil eines Heißbereichumrisses (38) sichtbar zu machen.
