INDOOR UNIT FOR FLOOR MOUNTED AIR CONDITIONER

摘要

Occurrence of noise caused by a collision of airflow discharged from a turbo fan with a casing is minimized. An indoor unit (1) is provided with a turbo fan (62) for generating airflow in a centrifugal direction, and also with a casing unit (50) having suction openings (51a, 51b) which sucks, from the outside, air supplied to the turbo fan (62) and also having discharge openings (52a, 52b) for discharging the airflow generated by the turbo fan (62).  The turbo fan (62) includes a main plate (63), a sub plate (64) provided on the discharge opening (52a, 52b) side relative to the main plate (63), and blades (65) provided between the main plate (63) and the sub plate (64).  The main plate (63) has an extended section (63c) tilted to the sub plate (64) side and extended from the outer end of the main plate (63) to the outside of the outer ends of the blades (65).  The sub plate (64) has an extended section (64b) tilted to the side opposite the main plate (63) and extended from the outer end of the sub plate (64) to the outside of the outer ends of the blades (65).
