Abstract

L'invention concerne un climatiseur qui supprime les craquelures dans une partie de fixation de vis d'un panneau fixé à une unité intérieure à l'aide de vis pour supprimer la fissuration et la rupture du panneau. Le climatiseur comprend : une unité intérieure qui aspire de l'air à partir d'une entrée d'air et qui souffle l'air aspiré à partir d'une sortie d'air à travers un échangeur de chaleur intérieur ; un panneau fixé à l'unité intérieure et présentant une entrée d'air de panneau en une position chevauchant au moins partiellement l'entrée d'air ; et une partie couvercle. Le panneau est pourvu, dans la périphérie de l'entrée d'air de panneau, d'une partie de fixation à laquelle est fixée une vis pour fixer le panneau à l'unité intérieure. La partie couvercle recouvre la vis et ferme hermétiquement la partie de fixation. La partie couvercle recouvre la vis et ferme hermétiquement la partie de fixation et, par conséquent, l'adhérence de l'huile ou du détergent dans l'air à la partie de fixation est supprimée. Grâce à la structure susmentionnée, des craquelures dans la partie de fixation de vis du panneau sont supprimées, ce qui permet la suppression de la fissuration et de la rupture du panneau.
