Abstract

L'invention concerne un système de cuisson comprenant un boîtier ayant une surface présentant une zone de préparation d'aliments et une zone de cuisson, et un capot destiné à être placé au-dessus des aliments sur la zone de cuisson pour définir une chambre de cuisson ou de chauffage entre la surface de cuisson et le capot, le capot mettant en œuvre une fonction de chauffage. Les aliments sont préparés sur une zone de préparation d'aliments de la surface. Les aliments sont ensuite soit transférés à la zone de cuisson, soit la zone de préparation d'aliments et la zone de cuisson peuvent être au même emplacement. Un capot de cuisson placé au-dessus des aliments comprend un élément chauffant électrique et forme une chambre avec la surface elle-même, de sorte que les aliments préparés n'aient pas besoin d'être soulevés pour être placés dans un récipient de cuisson.
