Abstract

La présente invention porte sur un appareil de cuisson électrique, dont un élément de commande est positionné séparément à l'extérieur, et dans lequel l'élément de commande est utilisé pour commander un appareil de chauffage électrique qui est disposé dans un corps principal. L'appareil de cuisson électrique comprend : un corps principal, qui comprend un corps de récipient, un chemisage en aluminium qui est positionné dans le corps de récipient et un appareil de chauffage électrique qui est disposé entre le chemisage en aluminium et le corps de récipient ; un récipient en céramique, qui peut être disposé de façon amovible dans le chemisage en aluminium ; un couvercle, qui est réalisé en verre trempé ; et un élément de commande, qui est séparé du corps principal et qui est connecté électriquement à l'appareil de chauffage électrique. Des boutons sur l'élément de commande peuvent être enfoncés pour régler des paramètres et démarrer l'appareil de cuisson électrique. L'élément de commande peut éviter une détérioration due à la chaleur, car il est retiré de la zone de la source de chauffage, ce qui est par conséquent plus sûr et plus fiable. Le corps de récipient est réalisé en acier inoxydable et est formé d'un seul tenant. Par conséquent, cette invention procure un appareil électrique qui est sûr, fiable, durable, et facile à fabriquer et à transformer.
