Abstract

L'invention concerne un appareil de sécurité pour gaz de table de cuisson. L'appareil comprend un ensemble soupape de sécurité pour gaz de cuisson qui alimente en gaz de cuisson un ou plusieurs brûleurs. L'ensemble de sécurité pour gaz de cuisson comprend au moins une bobine qui peut être excitée pour maintenir l'ensemble soupape dans une position ouverte lorsqu'elle est soumise à un courant qui dépasse une valeur de seuil et un circuit ouvert de maintien. Le circuit ouvert de maintien comprend la bobine et un allumeur de surface chaude qui est en communication électrique avec la bobine.
