Abstract
A combination compact microwave oven incorporates ventilator and cooling systems into a unitized structure which may typically be installed on a wall above a conventional electric or gas range. A ventilator assembly including centrifugal fans at the top backward edge is rotatably adjustable for different installations. The space under an outer housing is utilized as an exhaust duct containing a filter means through which exhaust gas can be discharged if there is no external vent available. Air is taken into the cooling system from above through an opening where relatively cool air is expected to be available and is passed through separate air flow channels for efficient cooling of individual areas and components.
