Definitions

  • the present invention relates to a baking oven according to the preamble of the claim 1, as known from JP-A-57120033.
  • the oven muffle with an enamel layer is provided.
  • the enamel coating serves as an anti-corrosion layer and on the other hand as an antioxidant layer.
  • Last the appearance of the oven muffle is determined by the enamel.
  • Object of the present invention is therefore, in an oven according to the preamble of claim 1, the performance characteristics of the oven muffle improve.
  • the protective layer is realized as a sol-gel hard layer.
  • a sol-gel functional layer is provided which provides different areas of the muffle walls with special properties. These properties may be, for example, a particularly simple cleanability, a special sliding behavior or catalytic properties.
  • the functional layer is realized as a layer about 10 ⁇ m, in particular about 2 to 3 ⁇ m thick. Due to the sol-gel technique, the deposited layers, despite their small thickness both on each other and on the metal have a high stability and a high adhesion.
  • the thickness of the protective layer is less than about 30 microns, especially less than 20 microns and more preferably between about 5 and 10 microns. Due to the low layer thickness occur in the muffle wall only low voltages. Furthermore, a very good heat conduction from the heating elements or the muffle wall to the muffle interior is ensured and a low susceptibility to cracking of the protective layer or a low probability of chipping is realized.
  • This thin protective layer provides adequate corrosion and oxidation protection as well as hard surface protection for the metal.
  • Such thin protective layers can procedurally simple, preferably in Sol-gel technology be realized.
  • the sol-gel layer is for example in a simple Dipping method applied to the muffle walls.
  • the low stoving temperatures compared to the enamelling technique from about 450 to 500 ° C low.
  • the applied sol-gel layers are for the during cooking typical temperatures suitable.
  • the hard layer preferably has a thickness of 5 to 10 microns.
  • the protective layer is transparent and serves the inside of the muffle wall as a reflector. This is particularly favorable when cooked with the help of heat radiation in the infrared range or in the visible light range becomes.
  • Such transparent layers can be easily displayed as sol-gel layers.
  • the protective layer may be anodised, in particular be realized hard anodized aluminum oxide.
  • This oxide layer is characterized in particular by its excellent hardness and smoothness.
  • the muffle wall has an insulating protective layer in the micron range, on which the heating element is applied directly by means of thick film technology.
  • the heating element also with more complex coating processes, for example thin-film technology, be realized.
  • the strength can be the muffle wall can also be reduced to, for example, about 0.4 mm.
  • the baking oven muffle is provided by a stabilizing frame supported from the outside. This is especially important when the thickness the muffle wall is only about 0.3 to 0.5 mm. By this almost halving the Wall thickness of the oven muffle compared to the previously known prior art the heating times and the heat distribution will be significantly improved. moreover can be saved by the low material thickness material. Besides, that will Weight of oven muffle significantly reduced.
  • Fig. 1 shows a cuboid oven muffle 1 made of stainless steel with five muffle walls 3. These are the two side walls, a bottom and a top wall and a Back wall.
  • the feed opening of the oven muffle 1 moves around a muffle flange 5.
  • the oven muffle 1 is made in one piece in a hydroforming process. at This deep-drawing process, the oven muffle, in contrast to conventional mechanically deep-drawn parts defects, such as uneven and large changes in wall thickness, visible drawing marks and a drawing bead, as well as diminished Surface quality and reduced dimensional accuracy not on.
  • sol-gel technology Be in a dipping or spraying a muffle inside 7 and a muffle outside 9 coated with a sol-gel layer 11 (Fig. 2).
  • sol-gel a colloidal system generated in micrometer scale (gel).
  • This gel is caused by drying Solvent removal compressed and then cured in a suitable manner or baked at a temperature of about 450 to 500 ° C.
  • the sol-gel layer is chemically bonded to the substrate especially tightly connected.
  • the resulting sol-gel layer is about 10 microns thick and forms on the muffle wall 3 made of stainless steel on both sides a hard surface with electrical Insulating properties. Furthermore, it forms a tarnish and oxidation protection for the stainless steel.
  • On the sol-gel hard layer are in at least one other Process step in sol-gel technique Functional layers on different areas of the Muffelinnenseite 7 applied.
  • the sol-gel functional layers have a thickness of about 3 microns.
  • the protective layer formed from the two sol-gel layers 11 is such transparent, that the heat radiation relevant for food preparation in the infrared or in the visible light range, the protective layer can penetrate and of the Stainless steel surface can be optimally reflected into the muffle interior (Fig. 2). If necessary is also a transparent or opaque coloring of the layers possible.
  • the sol-gel hard layer are in a subsequent step on the Muffle outside 9 meander-shaped heating conductor 13 applied in thick film technology (Fig. 3). Due to the particularly thin insulating layer between the heating 13th and the muffle wall 3 is a particularly favorable and uniform heat transfer possible.
  • the heating conductors 13 can be connected via conductor terminals 15 with electrical voltage be supplied.
  • the oven muffle 1 is finally in a muffle insulation 17 of fiber-free Insulation material, e.g. Perlite, embedded.
  • a muffle insulation 17 of fiber-free Insulation material e.g. Perlite
  • the oven muffle 1 whose wall thickness is only 0.4 mm, stabilized.
  • the Insulation shell 17 designed sufficiently resilient to thermal expansion the oven muffle 1 during heating during a baking process not to break.
