Abstract: A ventilation system for an oven is provided. A side duct assembly includes a substantially vertical exit duct portion adjacent to an oven cavity wrapper defining an oven cavity of the oven, the substantially vertical exit duct portion having an air intake configured to receive a cavity air flow from an air intake along a side of a cavity wrapper. The side duct assembly further includes an angled duct portion defining an air passage angled upwards and towards a rear of the oven, the angled duct portion having an input end configured to receive the cavity air flow from the top of the substantially vertical exit duct portion and an output end configured to provide the cavity air flow into a mixing zone at the rear of the oven for mixing the cavity air flow with an electronics air flow from oven electronics into a combined air flow.

Abstract: A combined ventilation hood and microwave oven system (10) with an overall vertical dimension (30) is provided, which is smaller than a conventional combined ventilation hood and microwave oven. One or more vent hood fans (66;74) are disposed on lateral sides of a microwave coo-king cavity (34) to draw in exhaust air (92;93) through one or more vent inlets (54;56;158;160) disposed on a bottom surface (20;156) and expel the exhaust air (92;93;162) through one or more vent outlets (46;52) defined on a surface of an outer wrapper (80) of the combined system. The low-profile combined ventilation hood and microwave oven system is coupled with a modular heating system (150;180) for heating food, which provides both functions within the space typically required by the conventional combined ventilation hood and microwave oven.

Abstract: A microwave includes an external enclosure having a top surface that defines a cooling air inlet and a cooling air outlet along a front edge thereof. An internal enclosure defines a cooking cavity within the external enclosure. A sidewall of the internal enclosure defines a first air passage, and a top wall of the internal enclosure defines a second air passage. A cooking component area is defined between the internal enclosure and the external enclosure adjacent the sidewall of the internal enclosure. A cooling fan is disposed within the cooking component area. The cooling fan is configured to direct air along a cooling air path from the cooling air inlet, through the cooking component area, through the cooking cavity, and to the cooling air outlet.
