Oven appliance with an air flow restriction door

An oven appliance, comprising:

• a housing defining a cooking chamber, the housing also defining an opening for accessing the cooking chamber of the housing;
• an upper heating element array positioned within the housing at a top portion of the cooking chamber;
• a baking stone positioned within the housing at a bottom portion of the cooking chamber;
• a lower heating element array positioned within the housing below the baking stone adjacent the bottom portion of the cooking chamber;
• a hollow casing positioned around the opening of the housing, the casing comprising an intake contiguous with the interior room ambient atmosphere about the housing and a venting exit contiguous with the interior room ambient atmosphere about the housing;
• an air handler operable to draw air from the interior room ambient atmosphere into the casing via the intake and discharge air from the casing to the interior room ambient atmosphere via the venting exit;
• a temperature sensor;
• a door selectively adjustable between an open position and a closed position, the door restricting fluid communication between the interior room ambient atmosphere and the cooking chamber when the door is in a closed position;
• a door retaining mechanism operable to retain the door in the open position such that the door permits fluid communication between the interior room ambient atmosphere and the cooking chamber;
• and
• a controller operatively connected to the upper heating element array, the lower heating element array, the door retaining mechanism, the air handler, and the first temperature sensor, the controller configured to receive a signal from the temperature sensor and, in response to the signal, to deactivate the upper heating element array, the lower heating element array, and the air handler and to release the door retaining mechanism.
