Abstract (en)
[origin: US6392203B1] A baking oven includes a metallic baking oven muffle that can be closed off on a front side by a door. The muffle walls have heating elements for heating the cooking chamber to over approximately 180° C. and/or for heating the food disposed therein to be cooked. The muffle has a protective layer covering the muffle walls at least on the inner side. To improve the use properties of the baking oven muffle, the thickness of the protective layer is less than approximately 30 mum. The protective layer is formed as a hard sol-gel layer having a thickness of approximately 10 mum, preferably, between approximately 5 and 10 mum. The protective layer is transparent. The inner sides of the muffle serve as a reflector. A functional sol-gel layer is disposed on the hard sol-gel layer. The functional sol-gel layer has a thickness of approximately 10 mum, preferably, 2 to 3 mum. When the muffle is aluminum, the protective layer is an anodized aluminum oxide layer. The heating elements are applied to an insulating protective layer with thick-film technology. A stabilizing frame is substantially formed by the baking-oven muffle insulation. The frame supports the muffle on its outside. A muffle wall thickness is approximately 0.3 to 0.5 mm, preferably, 0.4 mm. Protective layer thickness is less than 20 mum, preferably, between approximately 5 and 10 mum.
