Abstract
A cooking assembly comprising a countertop (6) and an induction cooking device (1) attached to the bottom (8) of the countertop (6). The induction cooking device comprises: an induction coil formed from a wire having a substantially uniform non-circular cross-section which is higher than it is wide and which is at a distance (d6) from a top surface (7) of the countertop between 10 and 50 mm, said induction coil having an outer diameter and an inner diameter which is at least equal to 40% of said outer diameter; a generator (15, 16) configured to supply an AC current to the induction coil with a frequency between 30 and 80 kHz; and a magnetic flux concentrator disposed underneath the induction coil and covering at least 50% of the bottom of the induction coil and having a relative magnetic permeability of at least 1000.

A cooking assembly comprising a countertop and an induction cooking device to be mounted underneath the countertop, the induction cooking device comprising:
- a frame;
- an induction coil supported by the frame and having a bottom and a top, the top being oriented towards the countertop and being positioned at a first distance from a top surface of the countertop, the first distance being between 10 and 50 mm, the induction coil being formed from a wire having a uniform non-circular cross-section having a width and a height, the height being larger than the width, said induction coil having an inner diameter and an outer diameter, said inner diameter being at least equal to 40% of said outer diameter;
- a generator connected to the induction coil and configured to supply an AC current to the induction coil, the AC current having a frequency between 25 and 80 KHz;
- and
- a magnetic flux concentrator disposed between the frame and the bottom of the induction coil, the magnetic flux concentrator covering at least 50% of the bottom of the induction coil and having a relative magnetic permeability of at least 1000.
