Abstract
Abstract An oven includes an oven structure having an oven interior, an oven door for closing the oven interior, the oven door having a transparent or translucent front plate for allowing viewing of the oven interior through the oven door, and visible adjustment and display elements for setting and displaying parameters relating to the operation of the oven. The adjustment and display elements are visual elements mounted to be covered by the front plate when the oven door is closed. The front plate has light absorbing coloration or a reflective, translucent coating to allow only the visual elements and the oven interior when illuminated to be viewed therethrough.
