OVEN DOOR WINDOW UNIT FOR SELF-CLEANING OVENS

摘要

A window unit for a door of a self-cleaning oven has three transparent panes of glass clamped in spaced relation to provide a self-contained unit to be mounted in the window opening of an oven door. The middle pane of glass is elevated by thermostatic means at oven cleaning temperatures, and strips of heat reflecting material on the middle and outer panes of glass permit viewing into the oven at temperatures within the cooking range and are arranged to reflect heat as well as block visibility at oven cleaning temperatures.
