Description

[Detailed description of the invention] This invention configures the air conditioner main body and the fan block separately, allowing various operations such as maintenance and attachment/detachment of the fan block between ceiling heights to be performed extremely efficiently and reliably without fear of danger. The present invention relates to a ceiling-embedded air conditioner that is intended to be installed in a ceiling-mounted air conditioner.

Normally, in ceiling-mounted or ceiling-mounted air conditioners, the fan block and the air conditioner body are integrated, so when performing various work such as maintenance, removal, or installation of the fan block, the air conditioning It was very difficult to work as one with the main body of the machine at all times, and the danger was extremely high, especially since the work was carried out at high places.

The present invention is an attempt to fundamentally solve such drawbacks, and the one end of the mouth frame 2 of the air conditioner main body 1 is extended outward to form a connecting piece 3. From the frame diameter A of the orifice frame 2 to the orifice outer diameter B
The purpose of the present invention is to provide a ceiling-embedded air conditioner characterized in that a mouth frame 5 of a fan block 4 formed with a small diameter fan block 4 is fitted and fixed, and both bodies are integrally connected. be.

The structure of a specific example of the present invention will be explained in detail below with reference to illustrative drawings. 1 is an air conditioner main body, 6 is a heat exchange coil 7 is a drain pan, and a duct connection port 8 and an air blowing port 9 are provided on the front and rear surfaces of the machine body, respectively. .

The external casing of the air conditioner main body 1 is formed into a box shape by a top plate, left and right side plates, and a bottom plate, and each end piece of the top plate, left and right side plates, bottom plate, etc. around the air outlet 9, that is, the mouth area. Frame 2... An end portion is slightly extended to the outside to form a connecting piece 3.

The fan block 4 has mechanisms such as a blower 10 and an electric motor 11 disposed therein, and has a frame 5 surrounding a connection opening with the main body connection part 3 on its front surface.

Note that the outer diameter B of the perioral frame 5 is at least as large as the main body 1.
It must be formed with a diameter slightly smaller than the diameter A of the two peripheral frames.

In such a structure, the fan block 4 can be easily connected to the main body 1 by simply inserting the connecting opening frame 5 of the fan block 4 into the opening surrounding frame 2 of the main body 1 using the extending connecting piece 3. It can be done. Furthermore, by riveting the connecting portion 12, the two bodies 1 and 4 can be more firmly connected.

Furthermore, as shown in the drawings, by forming a part of the extending piece around the mouth of the main body 1 into a bent piece 3', the connecting part becomes stronger, and the rivet head fixed in the bent piece 3' It can be said that it is completely hidden and the design is good.

As described above, in the ceiling-embedded air conditioner according to the present invention, the outer diameter B of the opening frame 5 of the fan block 4 is formed to be slightly smaller than the diameter A of the opening frame of the main body 1. 4 to the mouth frame 2 of the main body 1, the main body 1 can be easily and efficiently connected to the main body 1 without worrying about misalignment or tipping, even in particularly dimly lit places such as ceilings. Furthermore, by fixing the connecting joint portion with screws 12 or the like, it is possible to connect and fix both bodies more firmly and reliably.

Therefore, various operations such as maintenance of the fan block can be easily performed on the ground by simply attaching and detaching the fan block, and there is no need to work between high places on the ceiling as in the past, making it extremely safe. Not only can this be done reliably and efficiently, but it also has the advantage of being extremely strong since the connecting parts of both bodies are overlappingly connected by the mutual mouth frames 2 and 5. It is.

Claims (1)

[Claims for Utility Model Registration] One end of the mouth frame 2 of the air conditioner main body 1 is extended outward to form a connecting piece 3, and the connecting piece 3 has a shape that is larger than the frame diameter A of the mouth frame 2. This ceiling-embedded air conditioner is characterized in that a mouth frame 5 of a fan block 4 having a slightly smaller mouth circumference outer diameter B is fitted and fixed, and both bodies are integrally connected. The end frame 2 of the air conditioner body 1 is slightly extended outward, and a part of the frame 2 is formed into a bent piece 3', and the frame 2 of the fan block 4 is attached to the bent piece 3'. The ceiling-embedded air conditioner according to claim 1, characterized in that the frame 5 is fitted and fixed.
