Description

[Detailed Description of the Invention] Technical Field of the Invention The present invention relates to an air conditioner, and relates to an improvement in the piping structure on the outdoor side of the air conditioner.

Technical background of the invention and its problems Conventionally, the outdoor side of an air conditioner is as shown in Figure 1. That is, a compressor b, a heat exchanger c, and a blower (not shown) are arranged within the main body a. A muffler d is attached to the compressor b, and the muffler d is connected to the compressor b through a discharge side refrigerant pipe e. Furthermore, the compressor b and the heat exchanger c are communicated through a high-pressure refrigerant pipe f. this is,
It is bent into a substantially U-shape so that vibrations caused by the operation of the compressor b are not transmitted to the heat exchanger c as much as possible.
Further, a mounting bracket i is provided in a part of the main body a to which packed valves g and h are attached for connection to an indoor unit (not shown). One packed valve g and the compressor a are communicated through a low pressure refrigerant pipe j. A capillary tube k is connected to the other packed valve h, which communicates with the heat exchanger c.

The outdoor side is configured in this way, but with the recent trend toward thinner shapes and space saving, the piping space inside the main body a has become extremely small, and for example, when piping, it is difficult to form a high-pressure refrigerant pipe f. This is not only unreasonable, but also extremely troublesome to assemble. Furthermore, there is a disadvantage that there is not enough space for installing a soundproofing material to absorb the operating noise of the compressor a, and it is easy to leak to the outside.

Therefore, as shown in Japanese Utility Model Publication No. 54-27800, for example, the main part of the refrigerant piping is made up of two panels pasted together, and necessary auxiliary equipment is attached to this panel via connecting pipes. I was thinking of something that had changed.

However, this kind of structure has many technical difficulties, such as the development of molds necessary for manufacturing the panels, the technique of pasting the panel plates together, and the prevention of deformation by connecting the connecting pipes, and has the disadvantage of high costs. . In addition, other means must be used to prevent leakage of compressor noise.

Purpose of the invention The present invention aims to provide an air conditioner that facilitates assembly work in a narrow space within the main body, saves space for piping, and ensures the soundproofing effect of the compressor.

Summary of the invention This invention consists of a high-pressure side refrigerant pipe, a low-pressure side refrigerant pipe,
A capillary reach tube and the like are embedded in an elastic body, and this elastic body is interposed between a compressor and a heat exchanger.

Embodiment of the invention An embodiment of the invention will be described below with reference to FIGS. 2 and 3. In the figure, 1 is the main body of an outdoor unit of a split type air conditioner. This main body 1 is formed to be extremely thin in order to save space. A fin tube-shaped heat exchanger 2 that is bent into a substantially L-shape along the back side and one side inside the main body 1
will be placed. A blower 3 is arranged on this front side. A compressor 5 with a muffler 4 attached is disposed at one corner of the main body 1. A partition plate 7 is provided between the muffler 4 and the compressor 5 and the heat exchanger 2, to which a plate-shaped elastic body 6, which will be described later, is attached to a part.

As shown in FIG. 3, the plate-shaped elastic body 6 is made of, for example, an elastic rubber plate, a foamed synthetic resin material, or a soft synthetic resin material, and is made into a plate-shaped body as thin as possible. At the time of formation, the high-pressure refrigerant pipe 8, the low-pressure refrigerant pipe 9, and the capillary tube 10, which is a pressure reducing device, are buried, and both ends of each are protruded by only the necessary minimum length. Both the high-pressure and low-pressure refrigerant pipes 8 and 9 are bent into a substantially U-shape in the middle, and this is for the purpose of absorbing vibrations transmitted to each pipe by itself.

The plate-like elastic body 6 constructed in this way is
As shown in the figure, both ends of the refrigerant pipes 8 and 9 and both ends of the capillary tube 10 which are arranged and project from the compressor 5, the heat exchanger 2, and the packed valves provided on one side of the main body 1, respectively, are 11 and 12 to form a refrigeration cycle.

By communicating this outdoor unit with the indoor unit via a refrigerant connecting pipe, refrigeration cycle operation becomes possible. Noise is generated from the compressor 5 during this operation, but it is surrounded by a part of the wall surface of the main body 1 and the plate-shaped elastic body 6 to prevent leakage to the outside and prevent the noise from being generated by the plate-shaped elastic body 6. is absorbed. Furthermore, the compressor 5 vibrates as it operates, causing the high-pressure refrigerant pipe 8 and the low-pressure refrigerant pipe 9 to vibrate.
to communicate. However, since these are embedded within the plate-like elastic body 6, the vibrations of the refrigerant pipes 8 and 9 are absorbed.

Furthermore, when assembling the outdoor unit, necessary parts such as the heat exchanger 2, blower 3, and compressor 5 are placed in predetermined locations, and piping is provided in the necessary locations. However, since both the high-pressure and low-pressure refrigerant pipes 8 and 9 and the capillary reach tube 10 are buried in the plate-shaped elastic body 6 after being bent into a predetermined shape, the plate-shaped elastic body 6 is curved along the shape of the partition plate 7. You can fix this by using the screwdriver and then connect it to the required place. These buried objects can be easily connected without coming into contact with other required parts. Note that the piping work can be further facilitated by bending both ends of each of the refrigerant tubes 8 and 9 protruding from the plate-like elastic body 6 and both ends of the capillary tube 10 in accordance with the points to be connected in advance.

In the above embodiment, the outdoor unit of the split type air conditioner was explained.
The present invention is not limited to this, and can also be applied to the outdoor side of a window-type air conditioner, for example.

Effects of the invention The present invention allows piping to be housed in a very small space within the main body, improving workability, and further reducing the thickness of the main body, resulting in space savings. Furthermore, the elastic body absorbs the vibrations of the piping and also absorbs the operating noise of the compressor, making it quieter.
