BACKGROUND OF THE INVENTION
The present invention relates to an air conditioner including a compressor soundproofing material for suppressing noise generated in a compressor from leaking to the outside.
[0002]
[Prior art]
In an air conditioner equipped with a compressor in the casing, noise is generated by the operation of the compressor. And if this noise leaks to the outside as it is, it will impair surrounding comfort. Therefore, conventionally, a sheet-like soundproofing material is provided around the compressor, and the noise of the compressor leaking outside is reduced by this soundproofing material.
[0003]
As a conventional example of an air conditioner that uses this type of soundproofing material to reduce noise, for example, JP-A-10-220820 can be cited. In JP-A-10-220820, as shown in FIGS. 11 and 12, a compressor 1, an accumulator 2, and the like are disposed at an end of a bottom plate of an outdoor unit of an air conditioner. A compressor soundproofing material 3 is disposed so as to surround 1 and the accumulator 2. Above and around the compressor 1, well-known members are arranged in the air conditioner such as the four-way switching valve 4, the liquid closing valve 5, the gas closing valve 6 and the like for connecting these members. The 1st connection piping 7, the 2nd connection piping 8, and other connection piping are arrange | positioned. A body-wrapping soundproof material 11 is wound around the compressor 1, the accumulator 2, and various communication pipes. FIG. 11 is a view taken in the direction of arrow A in FIG.
[0004]
[Problems to be solved by the invention]
In such a conventional example, the above-described drum-wrapped sound insulating material 11 is merely disposed around the compressor 1 and the accumulator 2, and has a function of preventing the pipe from hitting a large number of connecting pipes 7, 8 and the like. I didn't have it. In other words, since the compressor 1 itself vibrates, there is a possibility that a large number of connecting pipes arranged in the surrounding area may vibrate. To prevent the adjacent connecting pipes 7 and 8 from being hit by the vibration, 11 is inserted between the first connecting pipe 7 and the second connecting pipe 8 to prevent the contact pipes 7 and 8 from hitting. Thus, in the past, a separate soundproof material 9 was used to prevent the contact pipes 7, 8 and the like from being hit in addition to the body-wrapped soundproof material 1. For this reason, there is a problem that the cost is increased by the amount of the soundproofing material 9 and the cost is increased due to an increase in the number of assembly steps.
[0005]
The present invention has been made in order to solve the above-mentioned conventional drawbacks, and its purpose is to reduce the cost by using common parts by preventing contact pipes from being hit by a soundproof material for a compressor.
