キュムレータにかぶせる等の方法によっていた。Conventionally, as a soundproofing measure for an air conditioner outdoor unit, a sound absorbing material or a sound insulating material without a three-dimensional molding is individually attached to a desired portion such as an inside wall of an air conditioner outdoor unit, or a method of filling a void is used. The sound absorbing material without molding is integrated with the sound insulation material, and the ends are sewn together and sewn together.
The sound absorbing material, which is in a cylindrical shape and has no three-dimensional shape, is covered with a compressor or an accumulator.

部品点数が５，６点にも及び取り付け作業が非常に煩雑
であり、特にシール性が悪く、騒音が漏れ防音効果に劣
り、更にコストも高くつくという欠点を有していた。However, in such soundproofing measures, the total number of parts of the soundproofing material is 5, 6 and the installation work is very complicated, and especially the sealing property is poor, the noise leaks and the soundproofing effect is poor, and the cost is also low. It had the drawback of being expensive.

た。Therefore, the inventors of the present invention have earnestly thought that by replacing with one or two three-dimensional soundproofing materials, a soundproofing effect equivalent to or better than that of the conventional five or six-point soundproofing material can be obtained, and further the mounting workability can be reduced. As a result of research, from the simple thing of just rolling up and sewing the conventional soundproofing material without the three-dimensional molding,
Sound-insulating material consisting of three-layer structure of sound insulation material / sound absorption material is integrally molded,
The three-dimensionally processed, one-sided tubular structure is coated with one or both of the compressor and accumulator in the outdoor unit of the air conditioner to obtain a soundproofing effect superior to conventional soundproofing materials of 5 and 6 parts. It was discovered that the present invention was achieved.

体化せしめればよりシール性に優れた立体成形防音材と
なし得る。The sound-insulating material three-dimensionally molded by such a method is rolled into a tubular shape, and the overlapping portions are adhered to each other to form a tubular shape with one opening. At this time, if the sound absorbing material in the overlapping portion is removed and the sound insulating materials are brought into contact and integrated with each other, a three-dimensional molded sound insulating material having a better sealing property can be obtained.

る。The three-dimensional molded soundproof material in the form of a cylinder has an internal structure of an air conditioner outdoor unit of a compressor having a supporting member.
It is preferable to design the opening portion to have a large diameter so as to cover the support member as well as to have a shape that contacts the compressor and the accumulator. Further, it is preferable to design the sound absorbing material at the end portion of the opening to be longer than the sound insulating material so that the sound absorbing material functions as a cushioning material with the bottom surface of the air conditioner outdoor unit to block vibration.
