Abstract

Cette invention se rapporte à une unité d'intérieur (2) pour climatiseur, qui permet d'éliminer les risques d'altération de l'aspect esthétique du panneau frontal (26a) de l'unité d'intérieur (2), laquelle comprend à cet effet un corps (26a) et un premier panneau décoratif (80). Le premier panneau décoratif (80) est opaque et comporte des pièces de montage (91b) et une couche décorative (27a). Dès lors que les pièces de montage (91b) sont montées sur le corps de l'unité, la pièce de montage est installée sur le côté arrière du premier panneau décoratif (80) et fait partie intégrante de ce premier panneau décoratif (80). La couche décorative (27a) est formée sur la surface arrière du premier panneau décoratif (80). La couche décorative (27a) est également au moins colorée. Puis, un traitement de dissimulation servant à dissimuler les pièces de montage est appliqué sur le premier panneau décoratif (80) au moins sur les parties de sa surface frontale opposées aux pièces de montage (91b).
