この従来例の圧縮機の支持構造における防振ゴムで使用されるエラストマ素材のゴムは、天然ゴム等の従来から一般的に使用されているゴムに比較すると柔軟性は大きく圧縮機の防振効果も大きいが、柔軟性が大きいために亀裂が発生してやすく耐久性が劣る問題が有った。   The rubber of the elastomer material used in the vibration-proof rubber in the support structure of the compressor of this conventional example is more flexible than the rubber generally used conventionally such as natural rubber, and the vibration-proof effect of the compressor However, there was a problem that durability was inferior because cracks were liable to occur due to the large flexibility.

この発明はこの点に着目し上記欠点を解決する為、特にその構成を、圧縮機を支持する基板と、前記圧縮機の支持脚と、前記基板上に支持脚を固定するための支持棒と、この支持棒の外周に内接する防振ゴムを備え、この防振ゴムの水平方向の動きを規制するリブを設けたものに於いて、前記防振ゴムは上下二段に積み重ね、上側の防振ゴムを天然ゴム等のゴム素材で形成し、下側の防振ゴムを前記上側防振ゴムよりも柔軟性の大きなエラストマ素材の樹脂で形成し、下側の防振ゴムの周囲に前記リブを設け、このリブの高さを下側防振ゴムの高さよりも低くしたものである。   The present invention pays attention to this point and solves the above-mentioned drawbacks. In particular, the structure includes a substrate for supporting the compressor, a support leg for the compressor, and a support bar for fixing the support leg on the substrate. The anti-vibration rubber inscribed on the outer periphery of the support rod is provided with ribs for restricting the horizontal movement of the anti-vibration rubber. The vibration isolator is formed of a rubber material such as natural rubber, the lower anti-vibration rubber is formed of an elastomer material resin that is more flexible than the upper anti-vibration rubber, and the rib is formed around the lower anti-vibration rubber. And the height of the rib is lower than that of the lower vibration-proof rubber.

この発明によれば、柔軟性の小さな上側防振ゴムと柔軟性の大きな下側防振ゴムを組み合わせることで圧縮機の振動やこの振動が原因で発生する騒音を極めて小さくすることができるものである。
また、リブの高さを下側防振ゴムの高さよりも低くすることで、リブと上側防振ゴムが接触して上側防振ゴムの振動が直接リブに伝達することを防止して振動の軽減を確実にすることができる。
また、下側防振ゴムの水平方向の歪みを減少することでエラストマからなる下側防振ゴムの亀裂の発生を減少して耐久性を向上することができる。 According to the present invention, the vibration of the compressor and the noise generated by this vibration can be extremely reduced by combining the upper vibration-proof rubber having a low flexibility and the lower vibration-proof rubber having a high flexibility. is there.
Also, by making the height of the rib lower than that of the lower anti-vibration rubber, the rib and the upper anti-vibration rubber are in contact with each other to prevent the vibration of the upper anti-vibration rubber from being transmitted directly to the rib. Mitigation can be ensured.
Further, by reducing the horizontal distortion of the lower vibration-proof rubber, it is possible to reduce the occurrence of cracks in the lower vibration-proof rubber made of elastomer and improve the durability.

次に、この発明に係る圧縮機の支持構造を図面に示された一実施例で説明する。
１は空気調和機や除湿機の基板で、樹脂材料の一体成型によって形成され、圧縮機２を固定する円柱状の支持棒３が３本等間隔に突設している。
前記圧縮機２は、等間隔に設けた３つの支持脚４を下部に備え、この支持脚４にはそれぞれ穴５を備え、この穴５に前記圧縮機２を支持する上側防振ゴム６が挿入されている。そして、この上側防振ゴム６の底面に接して上側防振ゴム６とほぼ同径の下側防振ゴム７を介して基板１上に載置されるものである。また、上側防振ゴム６と下側防振ゴム７は中心に貫通孔を備えている。 Next, a compressor support structure according to the present invention will be described with reference to an embodiment shown in the drawings.
Reference numeral 1 denotes a substrate of an air conditioner or a dehumidifier, which is formed by integral molding of a resin material, and has three cylindrical support rods 3 that fix the compressor 2 project at equal intervals.
The compressor 2 is provided with three support legs 4 provided at equal intervals in the lower part, each support leg 4 is provided with a hole 5, and an upper anti-vibration rubber 6 for supporting the compressor 2 is provided in the hole 5. Has been inserted. Then, it is placed on the substrate 1 through a lower vibration isolating rubber 7 which is in contact with the bottom surface of the upper vibration isolating rubber 6 and has substantially the same diameter as the upper vibration isolating rubber 6. Further, the upper vibration-proof rubber 6 and the lower vibration-proof rubber 7 have a through hole in the center.

前記上側防振ゴム６の材質は一般的に広く使用されている天然ゴムもしくはニトリルブタジエンゴム等を使用し、下側防振ゴム７はポリウレタンエラストマ等の常温で従来の天然ゴムよりも減衰率、弾性率が高い材質が使用され、上下で２種類の異なる減衰率のゴムを使用することで防振の効果を大きく発揮するものである。   Natural rubber or nitrile butadiene rubber or the like that is generally widely used is used as the material of the upper anti-vibration rubber 6, and the lower anti-vibration rubber 7 has a damping rate higher than that of conventional natural rubber at room temperature such as polyurethane elastomer. A material having a high elastic modulus is used, and two types of rubber having different damping rates are used on the upper and lower sides, so that the effect of vibration isolation is greatly exhibited.

前記支持棒３は中心にネジ穴８を設け、上方から金属製のワッシャー９とネジ１０によってネジ止め固定することで、製品輸送時等で前記圧縮機２の支持脚４が支持棒３から外れることを防止するものである。   The support rod 3 is provided with a screw hole 8 in the center, and is fixed with a metal washer 9 and screw 10 from above, so that the support leg 4 of the compressor 2 is detached from the support rod 3 when the product is transported. This is to prevent this.

１１は前記基板１と一体に支持棒３の周囲に円形に立設したリブで、リブ１１の高さＸを前記下側防振ゴム７の高さＹよりも低くすることで、圧縮機２からの振動が上側防振ゴム６を伝わり、上側防振ゴム６とリブ１１が直接接触してリブ１１に伝達することによって振動が大きくなることを防止して振動の軽減を確実にすることができる。   Reference numeral 11 denotes a rib which is erected in a circular shape around the support rod 3 integrally with the substrate 1. By making the height X of the rib 11 lower than the height Y of the lower vibration-proof rubber 7, the compressor 2 is provided. Is transmitted to the upper anti-vibration rubber 6, and the upper anti-vibration rubber 6 and the rib 11 are in direct contact with each other and transmitted to the rib 11, thereby preventing the vibration from increasing and ensuring the reduction of the vibration. it can.

また、下側防振ゴム７は柔軟性のために圧縮機２の荷重で水平方向に膨らむが、下側防振ゴム７の周囲をリブ１１で包囲することで、柔軟な下側防振ゴム６の水平方向の歪みを減少し、下側防振ゴム７の耐久性を向上することができるものである。また、リブ１１の内側で下側防振ゴム７接触する基板１側面は、下側防振ゴム７の底面に亀裂ができることを防止するためにできるだけ平坦に設けられている。   Further, the lower vibration isolating rubber 7 swells in the horizontal direction due to the load of the compressor 2 for flexibility. However, the lower vibration isolating rubber 7 is surrounded by the ribs 11 so as to be flexible. 6 can reduce the distortion in the horizontal direction and improve the durability of the lower antivibration rubber 7. Further, the side surface of the substrate 1 that contacts the lower vibration-proof rubber 7 inside the rib 11 is provided as flat as possible to prevent the bottom surface of the lower vibration-proof rubber 7 from cracking.

圧縮機２の組み付け手順について説明すれば、まず圧縮機２の３つの支持脚４に設けた穴５に上側防振ゴム６の上部を挿入して取り付けする。次に３つの下側防振ゴム７を支持棒３を貫通してリブ１１と支持棒３の間に位置させる。そして、下側防振ゴム７の上面に上側防振ゴム６が載るように支持棒３が上側防振ゴム６と支持脚４を貫通させ圧縮機２が基板１上に設置される。そして、支持棒３のネジ穴８にワッシャー９を介して上方からネジ止めすることで圧縮機２が取り付けられる。   The procedure for assembling the compressor 2 will be described. First, the upper part of the upper vibration-proof rubber 6 is inserted and attached to the holes 5 provided in the three support legs 4 of the compressor 2. Next, the three lower vibration isolating rubbers 7 are positioned between the rib 11 and the support bar 3 through the support bar 3. Then, the support rod 3 penetrates the upper anti-vibration rubber 6 and the support leg 4 so that the upper anti-vibration rubber 6 is placed on the upper surface of the lower anti-vibration rubber 7, and the compressor 2 is installed on the substrate 1. Then, the compressor 2 is attached by screwing the screw hole 8 of the support rod 3 from above through a washer 9.

以上のように、柔軟性の小さな上側防振ゴム６と柔軟性の大きな下側防振ゴム７を組み合わせることで圧縮機２の振動やこの振動が原因で発生する騒音を極めて小さくすることができるものである。また、リブ１１の高さＸを下側防振ゴム７の高さＹよりも低くすることで、リブ１１と上側防振ゴム６が接触して上側防振ゴム６の振動が直接リブ１１に伝達することを防止して振動の軽減を確実にすることができる。また、下側防振ゴム７の水平方向の歪みを減少することで下側防振ゴム７の耐久性を向上することができる。   As described above, the vibration of the compressor 2 and the noise generated due to this vibration can be extremely reduced by combining the upper vibration-proof rubber 6 having a small flexibility and the lower vibration-proof rubber 7 having a large flexibility. Is. Further, by making the height X of the rib 11 lower than the height Y of the lower vibration-proof rubber 7, the rib 11 and the upper vibration-proof rubber 6 come into contact with each other, and the vibration of the upper vibration-proof rubber 6 is directly applied to the rib 11. Transmission can be prevented and vibration can be reliably reduced. Further, the durability of the lower anti-vibration rubber 7 can be improved by reducing the horizontal distortion of the lower anti-vibration rubber 7.

尚、上側防振ゴム６の底面と下側防振ゴム７の上面を、予め接着剤や両面テープ等で接合して一体にして用いても良く、下側防振ゴム７の柔軟性に応じて下側防振ゴム７の高さＹ寸法やリブ１１の高さＸ寸法をそれぞれ調整するものである。   The bottom surface of the upper anti-vibration rubber 6 and the upper surface of the lower anti-vibration rubber 7 may be integrally joined with an adhesive or a double-sided tape in advance, depending on the flexibility of the lower anti-vibration rubber 7 The height Y dimension of the lower vibration-proof rubber 7 and the height X dimension of the rib 11 are respectively adjusted.
