Abstract

Cet appareil de cuisson est doté : d'une partie logement qui loge un objet à chauffer; d'un corps d'appareil de cuisson qui contient la partie logement; d'une partie chauffage qui est positionnée à l'intérieur du corps d'appareil de cuisson et qui chauffe l'objet à chauffer; d'un couvercle qui est fixé sur la partie supérieure du corps d'appareil de cuisson de façon à pouvoir l'ouvrir et à le fermer librement et qui peut être fermé de façon à couvrir la partie logement; d'un corps tournant (4) qui est positionné de manière rotative entre le corps d'appareil de cuisson et le couvercle; de corps de remuement similaires à des tiges (5, 6) destinés à remuer l'objet à chauffer à l'intérieur de la partie logement, lesdits corps de remuement (5, 6) présentant une première extrémité qui est fixée de manière rotative sur le corps tournant (4) et une seconde extrémité qui est positionnée sur le côté opposé à la première extrémité et qui peut être placée en s'éloignant du corps tournant (4) ou à proximité du corps tournant (4); et d'une partie entraînement qui génère une force d'entraînement qui force le corps tournant (4) à tourner. Lorsque les corps de remuement (5, 6) sont placés à peu près parallèles à la surface tournante du corps tournant (4), la largeur des corps de remuement (5, 6) dans la direction de la rotation devient plus étroite vers le dessus.
