Definitions

  • the invention relates to a transparent glass / glass ceramic plate for Products with a hot zone that produce a metal impression the side of the glass / glass ceramic plate facing away from the viewer a metallic foil / plate is attached.
  • a disadvantage of these known hobs with non-transparent glass ceramic plates decorated on the top side is that the ceramic decorative colors can only be applied in a relatively thin layer of only a few ⁇ m and do not have the desired brilliance in this layer thickness. Furthermore, due to printing-related difficulties, especially in the case of the fully-decorated cooking surfaces, the decor design and thus the appearance of the cooking surfaces are not free of restrictions. In addition, only. certain decorative colors are used that meet the requirements from practice (moving pots, cleaning overflowed and burned-in cookware, etc.), since the decorations applied to the top are exposed to high mechanical and chemical attacks, as is the case, for example, in DE 36 00 105 C2 is described. Furthermore, the decorations applied to the top of the glass / glass ceramic plate prevent the cooking surface from being as smooth as possible.
  • a hob with a transparent is not colored glass ceramic plate or a tempered glass plate
  • Special glass as a cooking surface that is heated with radiant heating elements Has cooking zones, on which decorations are applied, and their underside carries an IR-permeable layer of a temperature-resistant color, known in which the underside layer as a color-giving decoration is formed and the top of the glass ceramic or glass plate decor-free is.
  • the underside decoration is chosen in this way can be that a metal appearance is created in plan view of the cooking surface.
  • This can be achieved by using a temperature-resistant paint layer Metallic effects or by laminating a thin aluminum foil with highly transparent adhesives in the cold area of the cooking surface, i.e. except for Cooking zones, possibly in conjunction with a layer of paint temperature-resistant colors, especially single-layer or multi-layer Precious metal and / or luster color layer in the hot area.
  • FIG. This figure shows one Cooking surface 1 made of glass / glass ceramic with a cooking zone 2 through a Radiator 3 is heated.
  • the bottom of the hob is outside the cooking zone, i.e. in the cold area 4, by means of a layer 5 of transparent Glue applied a metal foil or metal plate 6.
  • On top of the A further decor 7 can be applied to the cooking surface.
  • the hot area i.e. the cooking zone with a transition area, is typically with a Color layer (not shown) made of temperature-resistant colors according to the state of the art.
  • the invention is therefore based on the object mentioned transparent glass / glass ceramic plate with metal appearance through an underside attached metal foil / plate so that due to the thermal operational loads no mechanical stresses can train between both partners.
  • clamping connection means can be made by springs be educated.
  • the arrangement is expediently such that a defined air gap is formed between the metallic foil / plate and the glass / glass ceramic plate.
  • the different coefficients of thermal expansion of glass / glass ceramic plates and metallic foils / plates can thereby be avoided.
  • the air gap is preferably a heat-conducting one Compensating medium, e.g. Filled silicone oil that adheres to the metallic Foil / plate reinforced and yet a balance between the produces different coefficients of thermal expansion.
  • Compensating medium e.g. Filled silicone oil that adheres to the metallic Foil / plate reinforced and yet a balance between the produces different coefficients of thermal expansion.
  • the arrangement is such that the calculation index of the compensating medium is adapted to that of the glass / glass ceramic plate.
  • the arrangement is such that the metallic foil / plate is attached outside the cooking zones and the Cooking zones an underside coating of temperature-resistant, have metallic-looking colors.
  • the cooking surface When used on cooking surfaces with atmospheric gas burners inserted, the cooking surface is designed in such a way that the metallic foil / plate is brought up to the use of the burner. This is possible because the temperature in the edge area of the insert is significantly lower than in the cooking zones with radiation-heated cooking surfaces.
  • Cooking surface 1 made of glass / glass ceramic with a radiation-heated cooking zone 2. Outside cooking zone 2, i.e. in the so-called cold area 4, is due to the Loosely attach a metallic foil / plate 6 to the underside of the cooking surface 1.
  • usual non-positive, but adhesive-free mechanical means ensure that the film / plate cannot detach itself.
  • film / plate 6 is applied by means of a clamp connection for example by springs and the like.
  • the metal foil / plate 6 can be profiled or be structured.
  • the surface can also be glossy or matt become.
  • the metallic foil / plate 6 is located directly on the underside of the glass / glass ceramic plate 1.
  • the thermal expansion coefficients of the glass / glass ceramic cooktop 1 and the metallic foil / plate 6 partly can be very different, despite the adhesive-free attachment
  • the metallic foil / plate is warped. This can be done according to the in Fig. 2 illustrated embodiment can be avoided by the metallic foil or plate 6 by means of a clamp connection behind the Glass / glass ceramic plate 1 is attached so that to bridge the different coefficients of linear expansion a defined air gap is introduced, which can be filled with various media in order to compensate for possible warpage of the metal foil.
  • the air gap has a width between 0.01 and 5 mm and can preferably with different thermally conductive compensating materials 8 that are to be filled from the refractive index to the Adjust the glass / ceramic hob to make them appear invisible.
  • the glass ceramic plate 1 has a refractive index of 2.54 As a leveling compound 8, a silicone oil with a refractive index of approx. 2.5 be used.
  • Fig. 3 an embodiment is shown in which the metallic Film / plate 6 by magnetic force on the underside of the glass / glass ceramic plate is kept glue-free, for example by the frame 9 of the Cooking surface is magnetized.
  • the hot area is left out.
  • This can with be printed on the underside, which the permeability in reduces the visible spectral range; the transmission in the visible Spectral range may be max. Amount to 50%.
  • commercially available glass ceramic paints can be used for this, which today for decorative purposes on the top of a non-transparent cooking surface Find use. The colors must be selected so that the strength the cooking surface is guaranteed.
  • Fig. 4 is an embodiment of the hob with an atmospheric Gas burner 10 shown.
  • the metal appearance of the gas hob effecting metal foil / plate 6 is lined as a frame, with between Foil / plate 6 and the underside of the glass / glass ceramic plate 1 analogous to the 2 a compensating layer 8 is provided.
  • a compensating layer 8 is provided.
