Title:
AIR CLEANER
Document Type and Number:
WIPO Patent Application WO/2022/176700
Kind Code:
A1
Abstract:
This air cleaner is provided with a duct through which air flows from a suction port to an outlet port, a light source which emits ultraviolet light into the duct from a downstream side toward an upstream side in the direction of flow of the air inside the duct, and a fan which discharges the air from inside the duct to the outlet port, wherein the light source and the fan are arranged side-by-side in a plane intersecting the direction of flow. For example, the duct includes an exposure portion for causing the ultraviolet light emitted from the light source to hit the air in the duct, and an electric dust collecting portion positioned on the upstream side of the exposure portion, wherein the electric dust collecting portion charges fine particles contained in the air in the duct, and collects the charged fine particles by means of an electrostatic force.
