Abstract

Selon l'invention, un boîtier d'unité intérieure (20a) d'une unité intérieure (20) est constitué par la combinaison d'éléments de bord (22G, 22D) sur les côtés gauche et droit d'un élément de face arrière (21). Des parties saillantes (30G, 30D) sont attachées aux éléments de bord sous la forme de composants séparés. Les parties saillantes servent à maintenir une distance qui n'est pas inférieure à une distance prédéterminée entre une surface de paroi dirigée vers des surfaces latérales de l'unité intérieure sur lesquelles sont disposées les parties saillantes et les surfaces latérales. Un panneau d'ouverture et de fermeture (28) apte à se déplacer vers le haut et vers le bas est disposé sur une surface avant du boîtier d'unité intérieure. Les bords gauche et droit du panneau d'ouverture et de fermeture s'enroulent autour des surfaces latérales gauche et droite du boîtier d'unité intérieure, et les parties saillantes jouent le rôle de parties structurelles reliées au panneau d'ouverture et de fermeture.
