Definitions

  • Such an inductor is known from the document WO 89/04109 wherein the design and arrangement of the inductor coils is such that in each field point outside the cooking area to be heated, which is covered by the parked pot, the field components of the individual inductor coils cancel each other substantially.
  • the inductor coils arranged one below the other are traversed by the feeding current in opposite directions.
  • a suitable ferrite element is arranged to shield the interfering field of the lower inductor coil between the two inductor coils.
  • Object of the present invention is to provide an inductor with the lowest possible minimum height.
  • a hob has a glass ceramic plate 1, below which an inductor 3 is mounted in the region of a marked hotplate. This has a coated on both sides, circular surface-shaped substrate plate 5 made of aluminum oxide with a thickness of about 0.8 mm. While a first spiral-shaped copper inductor coil 7 is applied to the upper side of the substrate plate 5 in the thick-film technique, the underside of the ceramic substrate plate 5 is coated with a copper coil material 9, which is also spirally formed. For the electrically conductive connection of the two inductor coils 7, 9 in their middle, the substrate plate 5 has a bore approximately in its center, which is formed as an electrically conductive plated-through hole 11.

Claims (10)

  1. Inducteur destiné à être disposé en dessous d'une plaque de cuisson d'un ensemble de plaque de cuisson à induction, comprenant au moins deux bobines d'inducteurs qui sont superposées à distance l'une de l'autre, caractérisé en ce que les bobines d'inducteur (7, 9) sont appliquées en tant que pistes conductrices plates (13) sur des côtés opposés d'un substrat (5) en forme de plaque.
  2. Inducteur selon la revendication 1, caractérisé en ce que le matériau du substrat (5) est une céramique oxydée, notamment un oxyde d'aluminium.
  3. Inducteur selon la revendication 2, caractérisé en ce que l'épaisseur du substrat (5) est d'environ 0,7 à 1 mm.
  4. Inducteur selon l'une quelconque des revendications précédentes, caractérisé en ce que la bobine d'inducteur (7, 9), est appliquée sur le substrat (5) comme spirale d'inducteur au moyen d'une technique de revêtement, notamment de la technique des couches épaisses.
  5. Inducteur selon l'une quelconque des revendications précédentes, caractérisé en ce que l'écart entre les spires de la piste conductrice (13) de la bobine d'inducteur (7, 9) en forme de spirale varie du centre de celles-ci vers la partie de bord.
  6. Inducteur selon l'une quelconque des revendications précédentes, caractérisé en ce que le substrat (5) présente une ouverture (11) de contact qui raccorde les deux bobines d'inducteur (7, 9) entre elles de manière conductrice.
  7. Inducteur selon l'une quelconque des revendications précédentes, caractérisé en ce que la piste conductrice (13) en forme de spirale de l'une des bobines d'inducteur (7) est essentiellement disposé spatialement dans la partie en forme de spirale entre les différentes spires de la piste conductrice de l'autre bobine d'inducteur (9).
  8. Inducteur selon l'une quelconque des revendications précédentes, caractérisé en ce que les deux bobines d'inducteur (7, 9) sont essentiellement exécutées de manière géométriquement égale, en ce qu'elles sont disposées essentiellement exactement l'une au-dessus de l'autre et qu'elles sont traversées dans le même sens par le courant électrique.
  9. Inducteur selon l'une quelconque des revendications précédentes, caractérisé en ce que les deux bobines d'inducteur (7, 9) forment un ensemble plat (3) avec des couches isolantes (15), disposées des deux côtés, et des éléments de ferrite (17).
  10. Ensemble de plaque de cuisson comprenant une plaque de cuisson en dessous de laquelle est disposé un inducteur selon l'une quelconque des revendications 1 à 9.
