A heating element for an inductive cooking hob comprises a flat spirally-wound coil (30) consisting of a plurality of parallel insulated conductors. The coil is wound in a spirally-extending groove (32) disposed on the upper surface of a plastics former (31). A circular base (33) of highly magnetically permeable material is disposed on the underside of the former (31). The base (31) focuses the magnetic field generated by the coil into a heating area above the coil, and also prevents any surrounding metalwork from inadvertently being heated.
Un élément chauffant pour une plaque de cuisson à induction comprend un serpentin plat enroulé en spirale (30) consistant en une pluralité de conducteurs parallèles et isolés. Le serpentin est enroulé dans une rainure (32) en forme de spirale disposé à la surface supérieure d'une plaque de support en plastique (31). Une base circulaire (33) constituée en un matériau à haute perméabilité magnétique est disposée sur la face inférieure de la plaque de support (31). La base (31) focalise le champ magnétique généré par le serpentin dans une zone de chauffe au-dessus du serpentin, et empêche également toute partie métallique environnante de chauffer de manière indue.
