Abstract

In a cooker with an at least partly translucent cooking or hob surface an operating or hot indication takes place through modular units surrounding the heating unit and which contain individual glow lamps and are spaced from one another around the circumference of the heating unit. They are fixed by holders to the outer rim of the heating unit and are electrically interconnected. Through a different wiring of the individual glow lamps or units it is possible to indicate different states of the heating unit.
