Abstract

La présente invention a pour objet de permettre à un ensemble couvercle de porte de fermer un orifice d'évacuation avant lorsqu'un ensemble ventilateur de fond n'est pas en fonctionnement, et de permettre à l'ensemble couvercle de porte de se déplacer hors de l'orifice d'évacuation avant de sorte que l'orifice d'évacuation avant soit ouvert uniquement lorsque l'ensemble ventilateur de fond est en fonctionnement, et qu'un ensemble enveloppe de ventilateur puisse ainsi faire saillie hors d'un ensemble porte, au moyen d'un actionneur, uniquement lorsque l'orifice d'évacuation avant est ouvert.
