Abstract

Une alarme selon la présente divulgation comprend : un capteur de fluide frigorigène pouvant détecter un fluide frigorigène ; un élément de notification pouvant fournir une notification indiquant que le capteur de fluide frigorigène a détecté le fluide frigorigène ; un substrat de capteur auquel le capteur de fluide frigorigène est fixé ; un boîtier qui reçoit le substrat de capteur en son sein ; et un élément interne logé à l'intérieur du boîtier. Le boîtier comprend une partie paroi de couvercle qui recouvre le substrat de capteur et le capteur de fluide frigorigène. Dans la partie paroi de couvercle, une fente est formée s'étendant dans une direction et reliant l'extérieur du boîtier et l'intérieur du boîtier. L'élément interne comprend une partie paroi opposée disposée en regard de la fente, et une première partie paroi en saillie faisant saillie à partir de la partie paroi opposée vers la partie paroi de couvercle et s'étendant dans une direction d'extension dans laquelle s'étend la fente. Sur une surface côté interne du boîtier de la partie paroi de couvercle, une seconde partie paroi en saillie est formée qui fait saillie vers la partie paroi opposée à partir d'une partie de bord d'une partie de bord périphérique de la fente, la partie de bord étant dans une direction d'intersection croisant la direction d'extension, et s'étend dans la direction d'extension. La première partie paroi en saillie et la seconde partie paroi en saillie comprennent des parties se chevauchant mutuellement lorsqu'elles sont vues dans la direction d'intersection.
