Multiblade diffusion fan assembly for attachment to ceiling cassette air conditioner

Abstract

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. 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. 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.

Description

technical field [0001] The present invention relates to a multi-blade diffuser fan assembly for ceiling embedded air conditioner attachment. The conventional ceiling-mounted air-conditioning indoor unit with four outlets in four directions of a suction grille in the center of the front surface has a very narrow airflow outlet range, so that the cold or hot air cannot be evenly dispersed, resulting in The efficiency of heating and cooling is reduced. In order to overcome the limitation of the airflow discharge structure of the conventional ceiling embedded air conditioner indoor unit, the present invention forms a multi-blade diffusion fan for the ceiling embedded air conditioner indoor unit. The above ceiling embedded air conditioner indoor The multi-blade diffuser fan for machine attachment can be directly attached to the ceiling-mounted air-conditioning indoor unit without changing the structure of the ceiling-mounted air-conditioning indoor unit, and receives the airflow fr...

AI Technical Summary

Problems solved by technology

[0008] As mentioned above, the diffuser fans for air conditioners in the prior art have many problems, and in order to overcome the problem that the cooling and heating efficiency can not be uniformly dispersed due to the extremely narrow range of the air flow of the ceiling-mounted air conditioner indoor unit in the past, Due to the limitations of the airflow discharge structure of the ceiling-mounted air conditioner indoor unit, a ceiling-mounted air conditioner indoor unit is attached with a multi-blade diffusion fan, which receives the discharge airflow and is driven in a non-powered manner, and the discharge air is introduced to the direction of the pivot axis. Generates radial outward airflow, and guides the outlet airflow to diffuse widely indoors, so that the air that is softer and fuller than the existing air-conditioning air can be widely diffused and supplied indoors, and users located in multiple directions can continue to feel it at the same time The air-conditioning wind can maximize the air supply efficiency and reduce energy consumption, and in the present invention, it just solves the technical problem of developing the above-mentioned ceiling-embedded air-conditioning indoor unit airflow diffusion fan
