Abstract

L'invention concerne un mécanisme de fonctionnement d'interrupteur de détection de vapeur pour chauffe-eau, qui permet un réglage l'état du détecteur de vapeur par l'actionnement d'un bouton-poussoir. Le mécanisme comporte un élément d'actionnement couplé au levier de déclenchement de l'interrupteur de détection de vapeur, qui sert à déplacer ce levier pour déterminer l'état de l'interrupteur, et un actionneur pour déplacer l'élément d'actionnement. L'actionneur est mobile transversalement par rapport à l'élément d'actionnement et comporte une partie d'extrémité qui, lorsque l'actionneur est enfoncé, s'engage dans une ouverture de l'élément d'actionnement ; des cames de l'actionneur coopèrent avec des surfaces d'élément rapporté de came situées dans l'ouverture. D'un côté de l'ouverture, la came de l'actionneur est une simple surface inclinée qui sert à déplacer l'élément d'actionnement dans une première direction ; et de l'autre côté de l'actionneur, la came est un élément monté pivotant qui est souple pour permettre un déplacement de l'élément d'actionnement dans cette première direction, mais ne permet qu'un mouvement pivotant limité dans la direction opposée. Lorsqu'on appuie une première fois sur l'actionneur, l'une des cames se met en mouvement de manière à déplacer l'élément d'actionnement dans une première direction ; lorsqu'on appuie une deuxième fois, l'actionneur sollicité par ressort et retournant à sa position de départ entre deux pressions successives, l'autre came se met en mouvement de manière à faire revenir l'élément d'actionnement dans la direction opposée.
