The present invention relates to a diffuser, and more particularly, to an improved structure for attaching the diffusion member to the diffuser housing to reduce the burden of the air conditioner because the discharge amount of the air discharged from the air conditioner is not limited. The present invention relates to a diffuser that is very easy to replace the filter that can remove the foreign matter before the air discharged from the air conditioner is discharged into the room.

The air conditioning system for discharging air into the building is divided into the centralized method and the ceiling buried method.

The central centralized method is to install a combination of one or more air conditioners in a certain place of the building and send air to the divided spaces through duct lines connected to the air conditioners.

In addition, the ceiling embedding method is a method in which the air conditioner is installed directly in the ceiling for each compartment in which the air is blown, and the air is discharged directly from the air conditioner directly to the interior. However, the ceiling embedding method has a disadvantage in that an air conditioner must be separately installed in each room where air is required to be blown, and a space must be secured inside the ceiling for installing the air conditioner.

On the other hand, it is discharged through the diffuser, which is the final discharge port, whether centralized or ceiling embedded, in the case of the conventional diffuser, as shown in Figure 6, the diffuser blades 500 on the inclined surface of the diffuser frame 400 Since it is to be attached, it can be seen that the diameter of the final discharge port is very small than the diameter of the blower opening of the diffuser body 100 connected to the duct. That is, there is a problem that the blowing area is limited by the diffuser to increase the blowing pressure from the air conditioner.

In addition, the conventional diffuser is to include a filter that can first remove the pollutants of the air flowing into the room, and secondly prevent the pollutants that can enter the duct from the room. However, as shown in FIG. 1, in order to replace the filter 200, the filter 200 may be replaced only after disassembling the diffuser blade 500, the diffuser frame 400, the damper 300, and the like. The exchange work is very cumbersome.

In addition, as shown in Figure 2, the filter 200 requires a filter housing for holding the filter material, because the area of the tuyere is reduced by the filter housing, this also causes the amount of blowing from the air conditioner is limited. It became.
