ABSTRACT:
A Toaster having heating elements whose heating area depends on the slice size. A toaster has heating elements (H1, H2) divided into sub-elements (H1A, H1B; H2A, H2B) which can be activated individually. The size of the product to be toasted (5) is detected by means of a sensor, for example a mechanical sensor (2) or an optical sensor device with a photo-emitter and a photo-receiver. The sub-elements are activated selectively in dependence on the detected size. Thus, the power consumption of the toaster is adapted to the size of the product to be toasted and overheating of the product in the proximity of the unused heating area of the heating elements is avoided.
