Title
(EN) COOKTOP GAS SAFETY VALVE HOLD OPEN CIRCUIT WITH CERAMIC HEATER
(FR) CIRCUIT OUVERT DE MAINTIEN DE SOUPAPE DE SÉCURITÉ POUR GAZ DE TABLE DE CUISSON AVEC ÉLÉMENT CHAUFFANT EN CÉRAMIQUE
Abstract
(EN) A cooking gas safety apparatus is shown and described. The apparatus includes a cooking gas safety valve assembly that supplies cooking gas to one or more burners. The cooking gas safety assembly includes at least one coil that is energizable to hold the valve assembly in an open position when subjected to a current that exceeds a threshold value and a hold open circuit. The hold open circuit comprises the coil and a hot surface igniter that is in electrical communication with the coil.
(FR) 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.
