Abstract

A pyrolytic self-cleaning oven door is provided having a window comprising a liquid crystal material, disposed between an inner surface and an outer surface of the window. The liquid crystal serves as an optical shutter. The shutter arrangement affects a change in light transmission therethrough in accordance with the temperature in the oven. The shutter is in a substantially opaque state when the oven is at a pyrolytic self-cleaning temperature and in a substantially transparent state, when the oven is at a temperature below a pyrolytic self-cleaning range.
