(EN) AIR PURIFIER
(FR) PURIFICATEUR D'AIR
(JA) 空気清浄機
Abstract
(EN) This air purifier (100) is provided with a housing (110), an intake port (120), a discharge port (125), an airflow generation unit (160), an ozone generation unit (140), and a downstream filter unit (150). The downstream filter unit (150) is arranged downstream of the ozone generation unit (140). The downstream filter unit (150) comprises a first filter, a second filter, a support unit and a housing unit. The first filter is arranged on one side. The second filter is arranged on the other side. The support unit supports the first filter and the second filter. The housing unit is formed between the first filter and the second filter. The housing unit houses a catalyst. The catalyst acts on the ozone.
(FR) Ce purificateur d'air (100) est pourvu d'un boîtier (110), d'un orifice d'admission (120), d'un orifice d'évacuation (125), d'une unité de génération d'écoulement d'air (160), d'une unité de génération d'ozone (140) et d'une unité de filtre aval (150). L'unité de filtre aval (150) est disposée en aval de l'unité de génération d'ozone (140). L'unité de filtre aval (150) comprend un premier filtre, un second filtre, une unité de support et une unité de boîtier. Le premier filtre est disposé sur un côté. Le second filtre est disposé sur l'autre côté. L'unité de support supporte le premier filtre et le second filtre. L'unité de boîtier est formée entre le premier filtre et le second filtre. L'unité de boîtier contient un catalyseur. Le catalyseur agit sur l'ozone.
(JA) 空気清浄機(100)は、筐体(110)と、吸気口(120)と、排出口(125)と、空気流発生部(160)と、オゾン発生部(140)と、下流フィルター部(150)とを備える。下流フィルター部(150)は、オゾン発生部(140)よりも下流側に配置される。下流フィルター部(150)は、第1フィルターと、第2フィルターと、支持部と、収容部とを有する。第1フィルターは、一方の側に配置される。第2フィルターは、他方の側に配置される。支持部は、第1フィルターと第2フィルターとを支持する。収容部は、第1フィルターと第2フィルターとの間に形成される。収容部は、触媒を収容する。触媒は、オゾンに作用する。
