An imaging system for a high-heat cooking appliance, including a camera system including an optical sensor, a lens, and a set of light emitters; and a camera cooling mechanism thermally connected to the camera system.

A door assembly for a microwave appliance includes a door frame that defines a door plenum and an air inlet. A monitor cradle is positioned toward a front of the door frame for receiving an image monitor. A duct is mounted to the door frame to divide the plenum into a low pressure region and a high pressure region, and an air handler is mounted to the duct to urge a flow of air from the air inlet, through the low pressure region, and into high pressure region. The flow of air cools electronics in the high pressure region before passing through an upper outlet that directs the flow of air along a surface of the image monitor and through a lower outlet that directs the flow of air along a transverse direction below the image monitor.

A door assembly for a microwave appliance includes a door frame that defines a door plenum and an air inlet. A monitor cradle is positioned toward a front of the door frame for receiving an image monitor seated on top of or flush with a front of the door frame. A duct is mounted to the door frame to divide the plenum into a low pressure region and a high pressure region, and an air handler urges a flow of air through the door plenum. A trim piece is removably mounted to a top of the door frame and includes a front guide that is spaced apart from the image monitor to define an upper outlet through which the flow of air passes downward along the vertical direction in front of the image monitor.

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.
