Abstract

La présente invention concerne un réfrigérateur (100) constitué, d'une part d'une armoire thermiquement isolée (150) qui définit une chambre de conservation et dont la façade présente une ouverture, et d'autre part d'une porte principale (111) qui ferme l'ouverture de la chambre de conservation de façon à pouvoir s'ouvrir et se refermer. La porte principale (111) est constituée d'un orifice (113) ménagé dans la façade de la porte principale (111), d'une portière (112) articulée pour fermer l'orifice (113) de façon à pouvoir s'ouvrir et se refermer, d'un axe (140) qui supporte en rotation la portière (112), d'un organe de verrouillage (141) monté en travers d'un espace défini entre, d'une part le chant de la portière (112) dans le sens de la longueur de l'axe (140), et d'autre part la face interne de l'orifice (113) en regard du chant de la portière, et d'un organe de commande (180) qui vient buter sur l'organe de verrouillage (141) quand la portière (112) est ouverte, de façon que la rotation de la portière (112) reste dans les limites d'un angle de rotation prédéfini.
