Microwave oven with gas or electric burner underneath - for alternative baking and has fan shaft carrying both circulation and suction fans

摘要

The main body has a heated chamber for the foodstuff to be baked and a magnetron radiating microwaves into the baking chamber. The latter is ventilated by an inlet and suction fan providing force feed air circulation via appropriate apertures in the oven chamber. The air circulation is assisted by a circulation fan (7) mounted in the oven chamber (2) in such manner, so as to be connected on the shaft (9a) common to the inlet and exhaust fan (6). Pref. underneath the oven chamber is mounted a heat source (11) with a gas burner for alternate baking. Instead of a gas burner the over chamber may be fitted with an electric heater. The fan shaft consists of an electric motor (9) shaft, fitted on the rear side of the oven body (1), the shaft carrying both fans (6, 7). The inlet and exhaust fan may be fitted in a housing (8) on the outside of the oven chamber rear wall (2a).
