Abstract

A kitchen workplate with an integrated cooking has a stone workplate (1) and a cavity structure (0) milled out at a predetermined position in an underside of the stone workplate (1) in which an induction coil (3) is placed. The cavity structure (0) and the induction coil form a cooking field. A reinforcement (6) provides a mechanical stabilization in the region of the cooking field in order to prevent crack formation in the stone workplate (1) resulting from thermal effects. A plurality of metallic distance (7) spacers are disposed on the surface of the stone workplate (1) and mark a place for placing cooking utensils into the cooking field and provide a thermal insulation employing air as a medium of insulation.
