Cooking range oven having insulated oven door with viewing system

摘要

A door for the oven of a cooking range includes an inner panel that closes the oven and an outer panel spaced from the inner panel. The inner and outer panels are connected adjacent their upper edges by an upper panel. The inner panel includes a first window in the form of a wide-angle lens. The upper panel includes a second window. Light-transmissive devices including a prism and a mirror are disposed between the inner and outer panels so as to direct light received through the lens upwardly and outwardly through the second window. The interior of the oven is illuminated by low-voltage halogen lights carried by the inner panel. The door is insulated by disposing a microporous metal oxide thermal insulation material against the oven side of the inner panel. The insulation is held in place by a plate. The door includes an oven-contacting gasket that extends beyond the boundaries of the plate to provide a thermal barrier when the door off the oven is closed.
