A partition is provided on the other side. A compressor 10, a connection pipe 7, an electric box 8, and the like are installed via a plate 5, and a machine room 6 having a front panel (not shown) is provided.

機械室６に設置された圧縮機１０は、図１に示すように、円筒状に形成されて密閉された本体部１１を有し、本体部１１の外面には電線接続部１２及び配管１３ａ，１３ｂが露出して設けられている。   As shown in FIG. 1, the compressor 10 installed in the machine room 6 has a main body 11 that is formed in a cylindrical shape and is hermetically sealed. On the outer surface of the main body 11, an electric wire connection portion 12 and a pipe 13 a, 13b is exposed and provided.

１５は圧縮機１０の本体部１１の外周に巻き付けられて防音装置を構成する防音材で、本体部１１の電線接続部１２に対応して開口部１７が設けられており、また、配管１３ａに対応して切欠き部１８ａが、配管１３ｂに対応して貫通穴１８ｂ（以下、両者を合わせて切欠き部１８という）がそれぞれ設けられている。１９は防音材１５の一方の縁部に設けられたマジックテープ（登録商標）である。   A soundproofing material 15 is wound around the outer periphery of the main body 11 of the compressor 10 to form a soundproofing device. An opening 17 is provided corresponding to the electric wire connecting portion 12 of the main body 11, and the pipe 13 a is provided with an opening 17. Correspondingly, a notch 18a and a through hole 18b (hereinafter collectively referred to as a notch 18) are provided corresponding to the pipe 13b. Reference numeral 19 denotes a magic tape (registered trademark) provided on one edge of the soundproof material 15.

この防音材１５は、図２に示すように、厚みｔ1の再生ゴム１６ｂと、厚みｔ2の高密度ゴム１６ｃ又はブチルゴム１６ｄ（以下、主として高密度ゴム１６ｃの場合について説明する）からなる異種ゴムを二層構造としたゴム層１６ａと、フェルト１６ｅとから構成されている。そして、これら再生ゴム１６ｂ、高密度ゴム１６ｃ及びフェルト１６ｅは、接着剤により接合され、又は締結具等の固定手段により一体に結合されている。 The soundproof material 15, as shown in FIG. 2, disparate consists of a reclaimed rubber 16b of the thickness t 1, the thickness t 2 dense rubber 16c or butyl 16d (hereinafter, will be described mainly high density rubber 16c) It is composed of a rubber layer 16a having a two-layer structure of rubber and a felt 16e. These recycled rubber 16b, high-density rubber 16c, and felt 16e are joined together by an adhesive, or are integrally joined by a fixing means such as a fastener.

上記のように構成した防音材１５は、フェルト１６ｅ側を圧縮機１０の本体部１１の外周側と対向させ、ゴム層１６ａ側を外側にして本体部１１に巻き付け、縁部に設けたマジックテープ（登録商標）１９により、両縁部をすき間なく合わせて固定する。このとき、圧縮機１０の電線接続部１２は開口部１７から、配管１３ａ，１３ｂは切除部１８からそれぞれ取り出される。なお、２０は防音材１５と同じ材料からなる円板状の天面部材で、圧縮機１０に巻き付けた防音材１５の上部開口部を閉塞する。このときの状態を図３に示す。   The soundproof material 15 configured as described above is wound around the main body 11 with the felt 16e side facing the outer peripheral side of the main body 11 of the compressor 10, the rubber layer 16a side outside, and a magic tape provided on the edge. (Registered trademark) 19 is used to fix both edges together with no gaps. At this time, the electric wire connection part 12 of the compressor 10 is taken out from the opening part 17, and the piping 13a, 13b is taken out from the cutting part 18, respectively. In addition, 20 is a disk-shaped top | upper surface member which consists of the same material as the soundproof material 15, and obstruct | occludes the upper opening part of the soundproof material 15 wound around the compressor 10. FIG. The state at this time is shown in FIG.

本発明に係る圧縮機１０によれば、防音材１５を、再生ゴム１６ｂと、高密度ゴム１６ｃ又はブチルゴム１６ｄとの異種ゴムを二層構造としたゴム層１６ａ、及びフェルト１６ｅによる多層構造とし、再生ゴム１６ｂと、この再生ゴム１６ｂより高密度で遮音性能の高い高密度ゴム１６ｃ又はブチルゴム１６ｄとを併用するようにしたので、再生ゴムからなる単層同一材料の防音材の使用量を増加することにより遮音するようにした従来の圧縮機に比べて、遮音効果を大幅に高めることができる。   According to the compressor 10 according to the present invention, the soundproofing material 15 has a multilayer structure including a rubber layer 16a having a two-layer structure of recycled rubber 16b and a high-density rubber 16c or a butyl rubber 16d, and a felt 16e. Since the recycled rubber 16b and the high-density rubber 16c or the butyl rubber 16d having a higher density and higher sound insulation performance than the recycled rubber 16b are used in combination, the use amount of the soundproofing material of the same material made of recycled rubber is increased. As a result, the sound insulation effect can be greatly enhanced as compared with a conventional compressor that is sound-insulated.

また、本発明によれば、ゴム層１６ａを構成する再生ゴム１６ｂの厚みｔ1と、高密度ゴム１６ｃ又はブチルゴム１６ｄの厚みｔ2とを異なる厚みとすることで、遮音性能を調整することができる。この場合、ゴム層１６ａの遮音性能を更に向上するためには、高密度ゴム１６ｃ又はブチルゴム１６ｄの厚みｔ2をより厚くすればよい。 Further, according to the present invention, the thickness t 1 of the reclaimed rubber 16b constituting the rubber layer 16a, by the thickness t 2 and the different thickness of the dense rubber 16c or butyl 16d, to adjust the sound insulation performance it can. In this case, in order to further improve the sound insulation performance of the rubber layer 16a may be thicker the thickness t 2 of the high-density rubber 16c or butyl 16d.

さらに、本発明によれば、再生ゴム１６ｂと、再生ゴム１６ｂより安価な高密度ゴム１６ｃ又はブチルゴム１６ｄとを併用することにより、従来の再生ゴムの使用量のみで対応した場合に比べて、防音材１５のコストを低減することができる。   Furthermore, according to the present invention, the combined use of the recycled rubber 16b and the high-density rubber 16c or the butyl rubber 16d, which is cheaper than the recycled rubber 16b, provides a soundproofing compared to the case where only the amount of conventional recycled rubber is used. The cost of the material 15 can be reduced.

また、ブチルゴム１６ｄは、再生ゴム１６ｂとその物性を比較した場合、反発弾性が低く、耐屈曲亀裂性が高いことから柔軟性があり、再生ゴム１６ｂとブチルゴム１６ｄとを併用することにより、従来の再生ゴムのみを用いた場合に比べて柔軟性が高められるため、防音材１５の圧縮機１０への巻き付け作業性を向上することができる。   Further, when the physical properties of the butyl rubber 16d are compared with those of the recycled rubber 16b, the butyl rubber 16d is flexible because of its low impact resilience and high resistance to flex cracking. By using the recycled rubber 16b and the butyl rubber 16d together, Since flexibility is increased as compared with the case of using only recycled rubber, the workability of winding the soundproof material 15 around the compressor 10 can be improved.

この場合、ゴム層１６ａの強度を高めるためには、再生ゴム１６ｂの厚みを増せばよい。なお、ブチルゴム１６ｄだけで使用量の増加により対応した場合は、柔軟性が高すぎて、圧縮機１０への巻き付け作業性が悪くなる。
また、本発明は、防音材１５をフェルト１６ｅを含む多層構造としたことにより、圧縮機１０に対して高吸音性が得られると共に、放熱ロスに対応することができる。 In this case, in order to increase the strength of the rubber layer 16a, the thickness of the recycled rubber 16b may be increased. In addition, when it respond | corresponds by the increase in usage-amount only with butyl rubber 16d, a softness | flexibility is too high and the winding workability | operativity to the compressor 10 worsens.
Further, according to the present invention, since the soundproof material 15 has a multilayer structure including the felt 16e, high sound absorption can be obtained for the compressor 10 and heat dissipation loss can be dealt with.

上記の説明では、図４に示した空気調和機の室外機に本発明に係る圧縮機を搭載した場合を示したが、これに限定するものではなく、他の構造の室外機にも本発明に係る圧縮機を搭載することができる。
さらに、本発明に係る圧縮機は、空気調和機以外の圧縮機を搭載する機器や装置にも使用することができる。 In the above description, the case where the compressor according to the present invention is mounted on the outdoor unit of the air conditioner shown in FIG. 4 is shown. However, the present invention is not limited to this, and the present invention is also applied to an outdoor unit having another structure. The compressor which concerns on can be mounted.
Furthermore, the compressor which concerns on this invention can be used also for the apparatus and apparatus which mount compressors other than an air conditioner.
