Title:
INDUCTIVE COIL UNIT COMPRISING CONDUCTIVE LAYERS
Document Type and Number:
WIPO Patent Application WO/2018/083058
Kind Code:
A1
Abstract:
The present invention relates to an inductive coil unit (1) suitable for use in full surface induction heating cooking ranges comprising a glass-ceramic table (3), on which pots (2) made of materials containing aluminum or copper having low magnetic permeability are placed, the coil unit comprising a plurality of coils (4) adjacent to each other and magnetically interacting with each other, arranged on the same alignment so as to cover almost the entire table (3) plane, each driven with the same phase (0°) or with 180° phase difference with respect to its adjacent other, and at least one conductive layer (6) having a plurality of segments (5) and made of a material with low magnetic permeability and high electrical conductivity, preferably of aluminum and placed between the coils (4) and the pot (2), eliminating the buoyancy problem forming during heating of the pots (2).
