Abstract

Official abstract text for this publication.

An indoor unit in an air conditioner configured to condition air in an indoor space includes: a casing that includes an intake port opened downward toward the indoor space; a fan configured to suck air in the indoor space into the casing via the intake port; a collector configured to collect dust contained in the air sucked via the intake port; a light source configured to irradiate an upstream side of the collector in an air flow direction with ultraviolet rays; a shield configured to block the ultraviolet rays from the light source toward the intake port; and a protecting member having a mesh shape and covering the intake port at a position upstream of the collector in the air flow direction.

First claim

Opening claim text (preview).

What is claimed is: 1. An indoor unit in an air conditioner configured to condition air in an indoor space, the indoor unit comprising: a casing that comprises an intake port opened downward toward the indoor space; a fan configured to suck air in the indoor space into the casing via the intake port; a first dust filter disposed adjacent to the intake port and that collects dust contained in the air sucked via the intake port; a second dust filter that: collects dust contained in the air sucked via the intake port at a position downstream of the first dust filter in an air flow direction, and has a finer mesh than the first dust filter; a light source configured to irradiate an upstream side of the first dust filter in the air flow direction with ultraviolet rays and disposed at a position where the light source does not overlap either of the intake port and the first dust filter when viewed along the air flow direction; and a shield configured to block the ultraviolet rays from the light source toward the intake port, wherein the first dust filter has a first surface having a planar surface as an upstream surface in the air flow direction, and the light source irradiates the first surface with the ultraviolet rays. 2. The indoor unit in the air conditioner according to claim 1 , wherein the light source irradiates the first dust filter with the ultraviolet rays in a state where a line perpendicular to the first surface is slanted toward the light source with respect to vertically downward.
