Abstract

La présente divulgation concerne un climatiseur comprenant un boîtier, un composant de conduit d'air et un ensemble ions négatifs. Le boîtier est pourvu d'une sortie d'air intérieure. Le composant de conduit d'air est agencé dans le boîtier. Le composant de conduit d'air comprend un corps de composant de conduit d'air, une rainure de montage, une première fente de limitation et un premier élément de fixation élastique à encliquetage. La rainure de montage est agencée dans le côté du corps de composant de conduit d'air qui est proche de la sortie d'air intérieur. La première fente de limitation est agencée dans une première paroi latérale de la rainure de montage. Le premier élément de fixation à encliquetage élastique est agencé sur une seconde paroi latérale de la rainure de montage. L'ensemble ions négatifs est agencé dans le boîtier. L'ensemble ions négatifs comprend un corps d'élément de montage et un bloc de limitation. Le corps d'élément de montage est inséré dans la rainure de montage et le premier élément de fixation à encliquetage élastique est agencé sur une paroi latérale du corps d'élément de montage par encliquetage. Le bloc de limitation est agencé sur le corps d'élément de montage et le bloc de limitation est inséré dans la première fente de limitation.
