ABSTRACT:
The invention is an oven ventilation system which uses sheets of moving air to remove heat and also to insulate the oven from the remainder of the room or vehicle in which the oven is located. More particularly, the ventilation system takes air from outside the room or vehicle and forms rapidly moving sheets of air which pass over the external surfaces of the oven. After passing over one or more of the external surfaces of the oven, the sheets of air are exhausted to the outside. Preferably, the ventilation system also comprises wall means for forming a chamber to separate the oven and ventilation system from the remainder of the room or vehicle.
