  • Patent number: 11979967
    Abstract: A combined ventilation and microwave oven system includes an external enclosure with a top portion defining recirculation vent outlets, a cooling air inlet, a cooling air outlet, and an outside vent outlet, first and second side portions, and a bottom portion defining a vent inlet. The vent inlet is connected with the recirculation vent outlets and the outside vent outlet via airflow pathways. A hood assembly is disposed within the external enclosure and includes a first hood fan disposed between the cooking cavity and the first side portion and a second hood fan disposed between the cooking cavity and the second side portion. The hood assembly is configured to direct air through the vent inlet and through an interior of the external enclosure. A cooling fan is disposed between the cooking cavity and the second side portion to direct air through the cooling air inlet and the cooling air outlet.
