Ein derartiger Backofen ist z. B. durch die DE-OS 27 57 059 bekannt geworden. Bei dieser bekannten Bauart werden in einer ersten Ausführung die Heizkörper für die Ober- und Unterhitze durch einen ersten Schalter betätigt, während das Umluftgebläse sowie der gegebenenfalls zugeordnete Heizkörper durch einen eigenen zweiten Schalter zugeschaltet werden können. In einer zweiten Ausführung der bekannten Bauart ist vorgesehen, daß der für das Umluftgebläse mit zugehörigem Heizkörper vorgesehene Schalter sowie der Backofen-Wählschalter für die Unter- und Oberhitze in einem einzigen Kombinations-Drehschalter vereinigt sind. Dieser Kombinations-Drehschalter besteht im wesentlichen aus zwei zueinander konzentrischen Drehringen bzw. Drehscheiben, welche unabhängig voneinander drehbar sind. Hierbei sind auf einer inneren Skala die wählbaren Temperaturwerte von 0°C bis 275°C für die Ober- und Unterhitze aufgetragen, während auf einer äußeren Skala Betriebssymbole für den kombinierten Heizbetrieb Ober- und Unterhitze zusammen mit Umluftbetrieb angeordnet sind. Die bekannte Bauart zeigt zwar eine Kombination von zwei Drehschaltern in einem einzigen Schalter, jedoch sind dabei immer noch zwei zueinander konzentrische Drehringe bzw. Drehscheiben vorhanden, die unabhängig voneinander drehbar sind und entsprechend betätigt werden müssen. Die bekannte Bauart zeigt überdies noch eine Ausführung, bei der der Heizkörper für die Oberhitze als Grillheizkörper verwendet werden kann.Such an oven is e.g. B. become known from DE-OS 27 57 059. In this known design, the radiators for the top and bottom heat are actuated by a first switch in a first embodiment, while the circulating air fan and the optionally assigned radiator can be switched on by a separate second switch. In a second embodiment of the known type, it is provided that the switch provided for the circulating air blower with associated radiator and the oven selector switch for the bottom and top heat are combined in a single combination rotary switch. This combination rotary switch essentially consists of two concentric rotating rings or rotating disks which can be rotated independently of one another. The selectable temperature values from 0 ° C to 275 ° C for the top and bottom heat are plotted on an inner scale, while operating symbols for combined heating operation top and bottom heat are arranged together with recirculation mode on an outer scale. The known design shows a combination of two rotary switches in a single switch, but there are still two concentric rotating rings or rotating disks which can be rotated independently of one another must be operated accordingly. The known design also shows an embodiment in which the radiator for the top heat can be used as a grill radiator.

  • c) daß einem der beiden Drehbereiche zusätzlich die Schaltfunktion des Umluftgebläses,
    gegebenenfalls mit der zugehörigen Heizfunktion, zugeordnet ist.
