  • Induction cooking device
    Patent number: 10542590
    Abstract: An induction cooking device including at least one inductor positioned under a thermally strengthened glass plate, the composition of which glass is not of lithium aluminosilicate type, characterized in that the glass has the following characteristics: its thickness is at most 4.5 mm, the c/a ratio of the glass before strengthening is at most 3.0 after Vickers indentation under a load of 1 kg, c being the length of the radial cracks and a being the half-diagonal of the Vickers impression, the ?/(e·E·?) ratio is at least 20 K·mm?1, or even 30 K·mm?1, ? being the maximum stress generated at the core of the glass by the thermal strengthening in Pa, e being the thickness of the glass in mm, E being the Young's modulus in Pa and ? being the linear thermal expansion coefficient of the glass in K?1 is provided.
