Definitions

  • the invention relates to a glass ceramic plate with a cooking surface at least one cooking zone, which is a radiator with an annular Lighting arrangement is assigned and by means of Lighting arrangement through a structured cooking zone display is optically delimited on the cooking surface.
  • the invention further relates to a method for representing an in structured cooking zone display on a serving as a cooking surface Glass ceramic plate, which has at least one cooking zone, the radiator is assignable.
  • Glass ceramic plates as cooking surfaces with individual cooking zones are firmer Part of modern kitchen equipment.
  • the cooking zones typically be part of the glass ceramic plate. However, you can also go through separate ceramic or metallic parts are formed that are in openings be used in the glass ceramic plate. To facilitate handling when setting up the cooking or roasting utensils on the cooking zones and for Optimal use of the thermal energy is visible on the cooking surface delimited.
  • the cooking zone display Various methods have been used to achieve this To show the cooking zone boundary, hereinafter called the cooking zone display. For example, it is possible by appropriate treatment in the As part of the production of the glass ceramic plate through the cooking zones corresponding patterns optically different from the other areas of the To represent glass ceramic plate.
  • the EP 0 540 876 A2 discloses an externally illuminated light guide Glass ring, which is integrated in the insulation ring of the radiator. This Illuminated glass ring then shows the circular cooking zone inside the Ring and can also be used to display residual heat.
  • An illuminated area defined as a ring on the cooking surface Cooking zone display also shows DE 40 04 309 A1, the delimitation this ring area compared to the other parts of the cooking surface Decor can be marked even more.
  • DE 197 00 551 A1 shows a ring around a conventional, resistance-heated cooking plate embedded in a glass ceramic plate applied status display in the form of a light ring, the ring-shaped transparent area of the glass ceramic plate by a corresponding ring-shaped interruption in one at the bottom of the glass ceramic plate applied non-transparent cover layer is formed.
  • the invention is based, for the one mentioned Glass ceramic plate as a cooking surface with at least one cooking zone, the one Radiator is associated with an annular lighting arrangement and which by means of the lighting arrangement by a structured in itself Cooking zone display is visually delimited on the cooking surface, with simple Means to provide a structured cooking zone display that is significantly and cheaper than the corresponding mica mask in the known case is to manufacture and which is easier to handle during assembly guaranteed.
  • This screen printing process ensures cost-effective and time-saving Application of the structured cover layer on the underside of the Glass ceramic plate.
  • Glass ceramic cooktops are known which are in non-heated areas are opaque from the bottom. With external lighting the interior of the hob is covered. For this, an organic opaque lacquer on the underside of the glass ceramic cooktop in the corresponding areas applied by means of screen printing.
  • the flat underside coating is therefore only used for Covering the unheated areas, a lesson that comes with the Teaching of the structured coating according to the invention as identification nothing in common with the heated cooking zone to display information Has.
  • a hob with a glass ceramic plate as Cooking surface whose cooking zones are a radiator, typically a Radiant heater with an annular lighting arrangement, preferably an externally illuminated light ring, is assigned separately to represent.
  • This hob can, for example, correspond to the input cited writings, but also according to other solutions.
  • FIG. 1 there are various examples of the glass ceramic plate patterns to be printed.
  • the Figure part A shows letters in mirror writing (because bottom view), the individually or in complete lettering to show the cooking zone display and possibly also the residual heat as transparent areas of the cover layer are printable.
  • Figure B shows a cooking zone display with a ring to each other arranged rectangles or squares as a printed structure.
  • Figure part C are plus signs lined up in a ring, against each other according to the figure part D the cooking zone display from printed Pieces of a circular arc.
  • Figure 1 shows only a few examples.
  • the structure can of course also have a different configuration, if only the delimiting function is guaranteed.
  • the application of the layer is symbolic in the sectional view Section of the glass ceramic plate 1 shown in FIG. 2.
  • the thickness of the layer 2 be sufficient to ensure that all surfaces to be covered are sufficiently opaque to get.
  • the layer thicknesses can range from a few ⁇ m to a few 1/10 mm, but they are preferably about 100 microns.
  • the long-term temperature resistance of the paint must be the same for all thermal Be guaranteed. Make sure that the paint layer neither burns down nor trickles through ashing. The symbolism must always can be recognized perfectly.
  • Such a temperature-resistant lacquer is, for example, an alkyd resin lacquer with inorganic components.
  • the underside coating 2 is advantageously applied by means of Screen printing. After the structured layer has been applied, the Glass ceramic plates dried, preferably in conventional ones Drying ovens.
  • the cooking zone display can also be used Residual heat indicator can be used.
  • the light ring is from the Residual heat contact of the power control activated.
