  • US 6 392 203 B1 discloses an oven, wherein a metal muffle is closed at the front by a door. The walls of the muffle have heating elements for heating the cooking space to over 180°C. The walls of the muffle are covered at least on the inside by a protective layer. The protective layer is less than 30 micrometer thick, and made of sol-gel resin. US 4,138,988 discloses a cooking oven, wherein a front wall encloses a front opening of the oven cavity. The front wall is constructed of sheet metal coated by a layer or layers of porcelain or the like material. Said layer or layers, respectively, have protective functions.
  • It is an object of the present invention to provide an improved front frame for an oven cavity of a cooking oven, wherein said front frame has protective as well as decorative properties.
  • The object of the present invention is achieved by the front frame according to claim 1.
  • According to the present invention the metal layer is coated by at least one protective and/or decorative coating made of an organic material, wherein at least a part of the protective and/or decorative coating is transparent, and wherein the protective and/or decorative coating includes at least one non-reflecting layer, and wherein the metal layer is partially uncoated in order to allow the creation of a special design, wherein the metal layer defines some parts of the front frame and the coating defines other parts of the front frame.
  • The core of the present invention is the use of the organic material in order to protect the metal layer of the front frame on the one hand and to allow an attractive design of said front frame on the other hand, wherein at least a part of the coating is transparent and the metal layer is partially uncoated. The coating made of the organic material may have different colours and surface structures, so that a plurality of various designs can be realized.
  • According to a preferred embodiment of the present invention at least a part of the metal layer is made of stainless steel. The stainless steel allows an attractive design and a protective surface.
  • Alternatively or additionally, a part of the metal layer is made of metal sheet. The metal sheet allows a low cost version of the inventive front frame.
  • Further, at least a part of the metal layer may be enamelled. The enamel coat has a protective as well as a decorative function.
  • Preferably, the metal layer includes at least one metal of the group of chromium, nickel, titanium, gold, silver, aluminium, copper, zinc, zirconium, platinum and/or one or more oxides thereof. These metals and oxides, respectively, contribute to the protective and decorative purposes.
  • According to the present invention at least a part of the protective and/or decorative coating is transparent. In this case the metal layer has substantially the decorative function and the coating has essentially the protective function.
  • According to the present invention the metal layer is partially uncoated. This allows the creation of a special design, wherein the metal layer defines one part of the front frame and the coating defines another part of the front frame.
  • According to the present invention the protective and/or decorative coating includes at least one non reflecting layer. Said non reflecting layer prevents any reflections at the surface of the front frame. For example, the non reflecting layer has a special refractivity. Such kinds of non reflecting layers are typically used at eyeglass lenses.
