WIPO Patent Application WO/2014/077293

Kind Code:

A1

Abstract:

An air purifier comprising the following: an air-sterilizing unit; and a fan device provided such that air circulates through said air-sterilizing unit. The air-sterilizing unit contains a housing and a UV-emitting element that emits deep-UV rays having wavelengths of 200 to 350 nm. The housing has a sterilization chamber, and said sterilization chamber has an air-intake opening and an air-discharge opening. The UV-emitting element is disposed in the housing so as to emit the aforementioned deep-UV rays towards the interior of the sterilization chamber. Either (A) at least part of the surface of the inside wall of the sterilization chamber comprises a UV-reflecting material that may be covered by a UV-transmitting material and/or (B) at least one reflector, at least part of the surface of which comprises a UV-reflecting material that may be covered by a UV-transmitting material, is disposed inside the sterilization chamber. After passing through the air inside the sterilization chamber, the deep-UV rays emitted by the UV-emitting element are reflected by either the inside-wall surface comprising a UV-reflecting material or the reflector surface(s) comprising a UV-reflecting material and thus pass through the air inside the sterilization chamber at least once more.
