本発明は、工゛アコンディショナー屋外機の防音対策に
関し、詳細には、立体成形した３層構造の防音材により

ディショナー用防音材に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to soundproofing measures for outdoor air conditioners, and more particularly, to soundproofing measures for outdoor air conditioners, in which specific parts are covered with three-dimensionally molded three-layer soundproofing material. Regarding soundproofing materials.
従来、エアコンディショナー屋外機の防音対策としては

しかしながらこのような防音対策にあっては防嵜材の総
部品点数が５．６点にも及び取り付は作業が非常に煩雑
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。Conventionally, soundproofing measures for outdoor air conditioners have been achieved by pasting individual sound absorbing materials or sound insulating materials without three-dimensional molding onto desired areas such as the internal side walls of outdoor air conditioners, filling voids, etc. The unmolded sound absorbing material was integrated with the sound insulating material, the ends were rolled up and the ends were sewn together, and the unmolded sound absorbing material was placed in a cylindrical shape over a compressor or accumulator. ′
However, in this type of soundproofing measure, the total number of parts of the shielding material is 5.6, and the installation work is very complicated.In particular, the sealing performance is poor, noise leaks, and the soundproofing effect is poor. Furthermore, it has the disadvantage of being expensive.
そこで本発明者らは、１つ又は２つの立体成形防音材に
代えることにより、従来の５．６点の防音材と同等以上
の防音効果を得、更には取り付は作業性をも軽減せんと
鋭意研究の結果、従来の立体成形のない状態の防音材を

一方又は双方を被覆することにより従来の５．６部品の
防音材に優る防音効果を得ることを発見し、本発明に至
った。Therefore, the inventors of the present invention obtained a soundproofing effect equivalent to or higher than that of the conventional 5.6-point soundproofing material by replacing it with one or two three-dimensionally molded soundproofing materials, and furthermore, the workability of installation was also reduced. As a result of extensive research, we have developed sound-absorbing materials, from simple sound-absorbing materials rolled up and sewn together without conventional three-dimensional molding.
Integrated molding of soundproofing material consisting of 3 layers of soundproofing material/sound absorbing material,
A soundproofing effect superior to the conventional 5.6-part soundproofing material can be obtained by using a three-dimensionally processed cylindrical material that covers one or both of the compressor and accumulator in an outdoor air conditioner unit. This discovery led to the present invention.
本発明になる吸音材としては、植物性、動物性、鉱物性
、合成樹脂性の繊維の１種以上と合成樹脂性結合材、難
燃剤等からなる嵩高性不織布、フェル上及びウレタン、
塩化ビニル等の合成樹脂性フオーム材等が使用できる。The sound absorbing material of the present invention includes a bulky nonwoven fabric made of one or more of vegetable, animal, mineral, and synthetic resin fibers, a synthetic resin binder, a flame retardant, etc., a fel fabric, urethane,
Synthetic resin foam materials such as vinyl chloride can be used.
本発明で使用する吸音材（１）と吸音材（１′）は必ず
しも同一のものである必要はなく、異なるものの使用で
も差し支えない。The sound absorbing material (1) and the sound absorbing material (1') used in the present invention do not necessarily have to be the same, and different materials may be used.
本発明になる遮音材としては、アスファルト、ゴム、合
成樹脂等のバインダー成分の１種以上と充填材成分を混
練し、圧延してなるシート状物を使用する。As the sound insulating material of the present invention, a sheet material is used which is obtained by kneading one or more binder components such as asphalt, rubber, synthetic resin, etc. and a filler component and rolling the mixture.
かかる遮音材を吸音材で挾置した３層構造一体止物とし
て使用することを必須とし、かかる構造の防音材となす
ことによって初めて所望の効果を得ることができるので
ある。It is essential to use such a sound insulating material as a three-layer integral structure sandwiched between sound absorbing materials, and the desired effect can only be obtained by making the sound insulating material of such a structure.
一体化方法としては、金型に吸音材及び遮音材を載置後
、圧縮成形する方法、インジェクションモールドに遮音
材を載置後フオーム材成分を注入発泡せしめる方法等が
ある。Examples of the integration method include a method in which a sound absorbing material and a sound insulating material are placed in a mold and then compression molded, and a method in which a sound insulating material is placed in an injection mold and then a foam material component is injected and foamed.
かかる方法により立体成形した防音材を筒状にまるめて
重なる部分を接着せしめ一方開口の筒状にせしめる。そ
の除重なり部分の吸音材を取り除き遮音材同士を麹触一
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 soundproofing material three-dimensionally formed by this method is rolled into a cylindrical shape and the overlapping parts are bonded to form a cylindrical shape with one opening open. If the sound absorbing material in the overlapped portion is removed and the sound insulating materials are integrated with each other, a three-dimensional molded sound insulating material with better sealing performance can be obtained.
筒状となした立体成形防音材は、支持部材を有する圧縮

働きを付与し、振動を遮断するため好ましいことである
。Considering the internal structure of the compressor air conditioner outdoor unit that has a support member, the cylindrical three-dimensional molded soundproofing material
It is preferable to design the opening portion to have a large diameter so as to cover the support member, or to make the opening portion contact the compressor or accumulator. Furthermore, by designing the sound absorbing material to be longer than the sound insulating material at the end of the opening, it is preferable that the sound absorbing material acts as a buffer between the bottom surface of the outdoor air conditioner and isolates vibrations.
