INDOOR UNIT OF AIR-CONDITIONING APPARATUS

摘要

PROBLEM TO BE SOLVED: To obtain an indoor unit of an air-conditioning apparatus including a propeller fan in the vicinity of an air inlet and capable of securing the strength of a casing and suppressing the degradation of performance by reducing an increase in the draft resistance of sucked-in air.

SOLUTION: In an indoor unit 1 of an air-conditioning apparatus, at least one propeller fan 10 having a fan guard 50 is disposed downstream of an air inlet 130 formed at the top of the indoor unit 1. The air inlet 130 is provided with bars 140. Each of the bars 140 is located in a virtual cylinder 13 obtained by projecting a boss 11 of the propeller fan 10 in the direction of the rotation axis of the propeller fan 10 in a vertical cross section perpendicular to the longitudinal direction of the bar 140.
