摘要： A ceiling-embedded air conditioner includes a decorative panel, a turbo fan, a heat exchanger, a drain pan, an air suction path, air blowoff paths provided at four places along the sides of a virtual square surrounding the air suction path, and an air blowoff opening communicating with the air blowoff path. The air blowoff path is formed in a cuboidal shape having a pair of long side walls disposed with a predetermined space therebetween in parallel to the sides of the virtual square and a pair of short side walls connecting the ends of the long side walls. Airflow guide vanes are provided in the air blowoff paths to direct part of blown airflow toward the short side of the air blowoff opening.

摘要： A ceiling-embedded air conditioner includes: a main unit; a decorative panel having an outer frame portion, an inner frame portion disposed more inside than the outer frame portion, and connection portions connecting the outer frame portion and the inner frame portion at corner portions; a blowoff path disposed between the outer frame portion and the inner frame portion; blowoff openings formed between the adjacent connection portions in the blowoff path; and wind direction plates covering the blowoff path. The wind direction plates include shaft portions. Plate-like bearing support columns are erected from the connection portions. The bearing support columns include at the tips shaft holes for supporting pivotally the shaft portions and include ventilation holes between the shaft holes and the connection portions.
