Abstract

Un aspect de la présente invention peut concerner un purificateur d'air, comprenant : un ensemble cadre qui comprend un boîtier ; une unité de ventilateur qui fournit une puissance de soufflage pour introduire de l'air extérieur dans le boîtier ; et un filtre principal qui filtre l'air introduit dans le boîtier pour fournir de l'air filtré. Le boîtier comporte une entrée pour introduire de l'air extérieur dans le filtre principal, un trou d'admission pour ajouter de l'air extérieur à l'air filtré, et une sortie pour évacuer l'air introduit à travers l'entrée et le trou d'admission ; et l'ensemble cadre comprend en outre une nervure qui est formée pour s'étendre sur le trajet d'écoulement de l'air filtré pour recouvrir le côté trou d'admission afin de retenir l'air filtré de s'écouler directement vers le trou d'admission.
