Abstract

La présente invention concerne une unité intérieure (100) d'un climatiseur au sol. L'unité intérieure comprend une enveloppe, un échangeur de chaleur (160) et un bac à eau (190), l'enveloppe comprenant une plaque arrière (101), un panneau de décoration gauche (110) situé sur le côté avant gauche de la plaque arrière (101), et un panneau de décoration droit (120) situé sur le côté avant droit de la plaque arrière (101), et la plaque arrière (101), le panneau de décoration gauche (110) et le panneau de décoration droit (120) entourent une cavité de réception ; et l'enveloppe comprend en outre une plaque de support gauche (108), une plaque de support droite (109), une plaque de support arrière (140) et une plaque de support avant (150). Les deux plaques de support longues gauche et droite, c'est-à-dire la plaque de support gauche (108) et la plaque de support droite (109), sont approximativement égales à la plaque arrière (101) en hauteur, et deux plaques de support courtes avant et arrière, à savoir la plaque de support avant (150) et la plaque de support arrière (140), forment une structure de support de noyau de l'unité intérieure (100) ; par comparaison à une structure de support d'une pièce de tôle métallique de type à fente haut-bas dans l'état de la technique, le nombre des différentes pièces de support à utiliser est réduit, le coût total de l'unité intérieure (100) est réduit, et en outre, les deux plaques de support longues sont utilisées, de sorte que la cohérence de la totalité de l'unité intérieure (100) est assurée dans la direction verticale, à savoir la direction de hauteur, de l'unité intérieure (100), et le problème de déviation est évité.
