The purpose of the present invention is to overcome a limitation of the air current discharge structure of an indoor unit of a conventional ceiling cassette air conditioner, of which efficiency of cooling and heating is degraded since the air current discharge range of the indoor unit of the conventional ceiling cassette air conditioner, installed on the indoor ceiling of a building and having four discharge ports formed to surround suction ports in four directions of one suction grille in the center of the front surface thereof, is very narrow, and thus low-temperature heat or high-temperature heat cannot be uniformly distributed. The present invention forms a multiblade diffusion fan for attachment to an indoor unit of a ceiling cassette air conditioner, which can be attached without changing the structure of the indoor unit of the ceiling cassette air conditioner, is driven without power by receiving a discharge air current, discharged from a discharge port of the indoor unit of the air conditioner, and generates an air current in an outwardly radial direction by introducing discharged air in the direction of a hub shaft and induces the discharge air current to be diffused widely in an indoor space. The present invention relates to a multiblade diffusion fan assembly for attachment to a ceiling cassette air conditioner, which is to be attached to an indoor unit of the ceiling cassette air conditioner, the multiblade diffusion fan assembly being driven without power by receiving a discharge air current, generating an air current in an outwardly radial direction by introducing discharged air in the direction of a hub shaft, and inducing the discharge air current to be diffused widely in an indoor space. |
