Abstract
A cooktop includes a printed circuit board having an upper side and operating elements on the upper side, a glass-ceramic cooking area having a plurality of cooking locations, and display elements. Each of the display elements have an illuminator and a display-symbol mask. The illuminator is assigned to one of the operating elements, is disposed underneath the glass-ceramic cooking area, and is secured on and in contact with the upper side of the printed-circuit board. The display-symbol mask is secured on the illuminator and is disposed between the glass-ceramic cooking area and the illuminator such that, when the illuminator is in operation, a display symbol corresponding to the display-symbol mask is seen through the glass-ceramic cooking area when viewed from above the glass-ceramic cooking area. The glass-ceramic cooking area can have no printed display-symbol inscription provided thereon, and/or can have no decorative printed inscription provided in a region on the surface above the illuminator. Further, the display-symbol mask can be secured on the illuminator at a distance from the underside of the glass-ceramic cooking area.
