Abstract

La présente demande concerne une structure de verrouillage, un ustensile de cuisson et un procédé de commande dudit ustensile. La structure de verrouillage comprend une première pièce de fixation et un premier ensemble de verrouillage. Le premier ensemble de verrouillage comprend : une première pièce d'appui ; une première pièce de verrouillage disposée sur la première pièce d'appui et verrouillée avec la première pièce de fixation lorsque la première pièce de verrouillage est mise hors tension ; et une première pièce de fonctionnement raccordée électriquement à la première pièce de verrouillage. Lorsque la première pièce de fonctionnement se trouve dans la première position, la première pièce de verrouillage est mise sous tension, de sorte que la première pièce de verrouillage soit séparée de la première pièce de fixation. Selon la présente demande, le premier ensemble de verrouillage et la première pièce de fixation coopèrent entre eux, de sorte que l'utilisateur qui souhaite ouvrir l'ensemble cavité soit obligé de mettre sous tension la première pièce de verrouillage avant d'ouvrir l'ensemble cavité. Ainsi, la situation dans laquelle un enfant ouvre par erreur l'ensemble cavité peut être évitée, et la sécurité d'utilisation de l'ustensile de cuisson est considérablement améliorée.
