Abstract

La présente invention se rapporte au domaine technique du conditionnement d'air. La présente invention concerne une unité intérieure de dispositif de conditionnement d'air, comprenant un boîtier comportant une sortie d'air, une porte d'ouverture et de fermeture souple agencée dans le boîtier de façon à ouvrir ou à fermer la sortie d'air, et un ensemble d'entraînement agencé dans le boîtier et relié à une première extrémité de la porte d'ouverture et de fermeture souple, amenant ainsi la porte d'ouverture et de fermeture souple à s'enrouler ou à se dérouler pour ouvrir ou fermer la sortie d'air. L'ensemble d'entraînement est relié à la première extrémité de la porte d'ouverture et de fermeture souple, et la porte d'ouverture et de fermeture souple est enroulée autour de l'ensemble d'entraînement à partir de la première extrémité. L'ensemble d'entraînement amène la porte d'ouverture et de fermeture souple à s'enrouler ou à se dérouler de façon à ouvrir ou à fermer la sortie d'air, la zone d'écoulement d'air de la sortie d'air étant déterminée par le degré d'enroulement de la porte d'ouverture et de fermeture souple. Entraînée par un seul ensemble d'entraînement, la porte d'ouverture et de fermeture souple se déplace sous l'effet d'une force de tirage dans un seul sens, ce qui l'empêche de se déformer sous l'effet d'un fort tirage, lui permet de se déplacer en douceur lors de l'ouverture ou de la fermeture de la sortie d'air, et lui assure une longue durée de vie.
