  • each induction coil (4) In the aluminum sheet (3) above each induction coil (4), holes (7) are made, their diameters slightly exceeding the diameters of the induction coils (4) by about 2 mm. This allows free contact of the induction coils (4) with the ceramic sheet (1) and facilitates the process of energy passing through the ceramic, respectively, saving it.

Thermistors (5) are attached to the underside of the ceramic sheet (1). Moreover, the controller (not shown in FIG.) Of the induction cooker is programmed in such a way as to prevent overheating of the upper layer of the ceramic sheet. After heating the surface to 200 ° C, the controller automatically reduces the heating power from 100% to 60%; when the stove is heated to 220 ° C, the operation of induction coils (4) completely stops.

  • the marking injected in this way is durable and resistant to temperature changes, as well as to scratches.
  • ceramic paints are used - these are colored mineral compounds of metals with quartz, feldspar, kaolin or with ceramic masses and glazes formed as a result of interaction at high temperatures. The intensity and color of the paint depends on the firing temperature.
  • Coloring substances (dyes) in ceramic paints are pigments - salt oxides, highly dispersed powders of various colors, insoluble in water and binders. The pigment determines the color, the tint component changes the hue of the color.
  • ceramic paints contain fluxes. It is possible to burn paint in a similar way at a temperature of 600-800 ° C.
  • Ceramic paints have the following properties:
  • a plate control unit (8) is installed on the upper surface of the ceramic sheet (1).
  • location of induction coils for cooking can also significantly save energy and reduce cooking time, because it allows the user to accurately place cookware over induction coils to maximize the transfer of energy from the coils to the product, since inaccurate installation of dishes negatively affects energy consumption and cooking time .
  • the applied marking does not reduce the strength characteristics of the countertop.

Abstract

Le modèle d'utilité concerne des équipements de cuisine et notamment des plans de travail à élément chauffants par induction intégrés. Le résultat technique consiste en une réduction de l'épaisseur de la couche supérieure du plan de travail tout en préservant ses caractéristiques en termes de résistance, ce qui permet de réduire la consommation énergétique et le temps nécessaire à la préparation d'aliments. Le plan de travail à plaque à induction intégrée est constitué d'une feuille céramique possédant des côtés inférieur et supérieur plats et une surface de cuisson sur son côté supérieur sur lequel on a appliqué un marquage dans les endroits où il est prévu de disposer des bobines d'induction au moyen d'un peinture pour céramique intégrée par cuisson. La feuille céramique est collée sur le substrat dans lequel on a réalisé une coupe traversante au niveau de la zone de surface de cuisson. Entre la feuille céramique et le substrat dans la zone de la surface de cuisson on a monté en tant que radiateur une feuille d'aluminium dans laquelle on a réalisé des orifices, dont les dimensions dépassent celles des bobines d'induction, pour assurer le contact desdites bobines de la feuille céramique. Entre les bobines d'induction et la feuille céramique on a disposé une feuille de papier ciré. Au moyen d'un mastic thermiquement résistant, on a collé à une partie de la feuille céramique dans la zone où sont disposées les bobines d'induction une grille en fibre de verre. Au centre de la grille en fibre de verre on a réalisé des orifices dans lesquels on a monté et fixé des thermistances.
