Abstract

An indoor unit for an air conditioner is provided with a heat exchanger (4) that encloses the direction in which air is discharged from a blower fan, a drain pan (5) disposed below the heat exchanger(4), and an antimicrobial unit (15) installed in the drain pan (5), the antimicrobial unit (15) having an antimicrobial agent for sterilizing drain water. At least part of the antimicrobial unit (15)is disposed directly below the heat exchanger (4). Thereby provided is an indoor unit for an air conditioner in which an antimicrobial agent is installed in a drain pan (5) while any reduction in thecross-sectional area of an outlet air duct is minimized.

Description

technical field [0001] The present invention relates to an indoor unit of an air conditioner, and more particularly to an indoor unit of a ceiling-embedded air conditioner. Background technique [0002] As the indoor unit of the air conditioner, there is the type (ceiling inlay) that the indoor unit is embedded in the ceiling. The indoor unit of the ceiling-mounted air conditioner rotates a centrifugal fan to suck in indoor air, cools the sucked air with a heat exchanger, and blows it out from an outlet to cool the room. [0003] In such an indoor unit of an air conditioner, condensed water is generated in the heat exchanger during cooling operation, and the condensed water stays in a drain pan and is discharged to the outside of the indoor unit by a drain pump. However, since the drain pump cannot discharge condensed water lower than its suction limit height, a certain amount of condensed water must remain in the drain pan after the operation stops. Bacteria multiply in t...
