Abstract

L'invention concerne une unité intérieure destinée à un climatiseur et comprenant : un échangeur de chaleur ; un dispositif de soufflante qui souffle de l'air dont la température est ajustée par l'échangeur de chaleur ; un boîtier qui loge l'échangeur de chaleur et le dispositif de soufflante ; et une persienne qui pivote et dévie la direction de l'air qui est soufflé vers l'intérieur d'une pièce à partir du dispositif de soufflante. Le boîtier a une première surface plate, une deuxième surface plate qui est sensiblement perpendiculaire à la première surface, et une troisième surface plate qui est interposée entre la première surface et la deuxième surface selon un angle par rapport aux deux surfaces. La persienne est disposée au même niveau que la première surface et la troisième surface dans l'état avant le pivotement.
