COMBINED MULTI-BLADE DIFFUSION FAN ASSEMBLEY FOR 4-DIRECTION CEILING-MOUNTED CASSETTE TYPE AIR CONDITIONER

摘要

An objective of the present invention is to overcome a limitation of an air current discharge structure of an indoor unit of a conventional ceiling-mounted cassette-type air conditioner which lowers cooling and heating efficiency since a discharge range of the conventional ceiling-mounted cassette-type air conditioner installed on an indoor ceiling in a building and provided with four vent holes surrounding a suction hole and a suction grille formed on a center of a front surface thereof in four directions is small and thus low-temperature heat or high-temperature heat cannot be uniformly distributed. To achieve the objective, the present invention provides a multi-blade dispersion fan assembly for mounting on ceiling-mounted cassette-type air conditioner which can be mounted on an indoor unit of a ceiling-mounted cassette-type air conditioner without changing a structure of the indoor unit of the ceiling-mounted cassette-type air conditioner, be driven without power by using a discharge air current discharged from the indoor unit of the air conditioner, generate an air current in an outwardly radial direction by sucking discharged air towards a hub shaft, and disperse the discharged air current in a wide angle in an indoor space.
