Abstract

<P>PROBLEM TO BE SOLVED: To provide a highly reliable multicylinder compressor not having the thermal effect in welding of the gas-liquid separator on the compression mechanism part, so as to solve problems that, when a gas-liquid separator is welded in a two-cylinder compressor, a connection pipe and a connection outer pipe are expanded or contracted caused by thermal effect to give excessive load on a compression mechanism part, thereby resulting in mechanical distortion and eccentricity to deteriorate the performance and lower the reliability. <P>SOLUTION: Upper and lower connection pipes 6 or the lower connection pipe 6 have/has a press-fit part(s) with smaller outer diameter at a certain distance from a tip. Even if displacement of the connection pipe is generated because of expansion and contraction in a length direction in the welding, its contact length with a suction port is kept to be constant, variation in press-fit load in assembly is suppressed, and increase in load caused by the thermal effect is avoided. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

本発明は空気調和装置等に使用される多気筒を有する圧縮機に関するものである。   The present invention relates to a compressor having multiple cylinders used in an air conditioner or the like.

従来の多気筒圧縮機は、図６に示すように密閉容器1内部に第一の圧縮機構部２が溶接固定され、その下部に第二の圧縮機構部３が、ボルト４で締結固定されている。両圧縮機構部の吸入孔５には接続管６が圧入され、容器１に取り付けた接続外管７と共に気液分離器８に溶接固定されている。   In the conventional multi-cylinder compressor, as shown in FIG. 6, a first compression mechanism 2 is welded and fixed inside the hermetic container 1, and a second compression mechanism 3 is fastened and fixed to the lower part by a bolt 4. Yes. A connecting pipe 6 is press-fitted into the suction holes 5 of both compression mechanisms, and is welded and fixed to a gas-liquid separator 8 together with a connecting outer pipe 7 attached to the container 1.

上記構成において、気液分離器８を溶接固定する際、接続管６と接続外管７が温度上昇と共に熱膨張した状態で接着される。その際、温度上昇のムラ及び、接続管６と接続外管７の材質の相違等により冷却時の収縮率が違う為、接続管６が冷却時に吸入孔５に過大な荷重で再圧入され、精密組立された圧縮機構部２，３の内部に変形を与える可能性がある。また、第二の圧縮機構部３においては、ボルト締結力を超える荷重が発生した場合芯ずれを起こす危険性がある。その結果、性能特性は当然ながら、信頼性悪化、起動不良への影響が懸念される。   In the above configuration, when the gas-liquid separator 8 is fixed by welding, the connecting pipe 6 and the connecting outer pipe 7 are bonded together in a state where they are thermally expanded as the temperature rises. At that time, since the shrinkage rate at the time of cooling is different due to uneven temperature rise and the difference in the material of the connecting pipe 6 and the connecting outer pipe 7, the connecting pipe 6 is re-pressed into the suction hole 5 with an excessive load during cooling. There is a possibility of deforming the inside of the compression mechanisms 2 and 3 that are precisely assembled. Moreover, in the 2nd compression mechanism part 3, when the load exceeding a bolt fastening force generate | occur | produces, there exists a danger of causing misalignment. As a result, there is a concern that the performance characteristics will naturally deteriorate in reliability and affect startup failures.

従来の技術としては、熟練工による短時間での溶接技術により熱影響を極力抑え製品特性を確保していた。
特開平０６−３０７３６４号公報 As a conventional technique, the heat effect is suppressed as much as possible by a short-time welding technique by a skilled worker to ensure product characteristics.
Japanese Patent Laid-Open No. 06-307364

しかしながら、上記従来の方法では人為的な作り込みによる為、製品にバラツキが生じやすく、溶接不良による洩れといった二次災害を引き起こす原因になる。   However, since the above-described conventional methods are artificially built, the products are likely to vary and cause secondary disasters such as leakage due to poor welding.

本発明は、上記従来の課題を解決するもので、気液分離器８溶接時の熱影響を圧縮機構部２，３に与えることなく信頼性の高い多気筒圧縮機を提供することを目的とする。   An object of the present invention is to solve the above-described conventional problems, and to provide a highly reliable multi-cylinder compressor without giving the heat influence during the gas-liquid separator 8 welding to the compression mechanism units 2 and 3. To do.

上記課題を解決するために本発明は、上下または、下側の接続管６の圧入部外径を先端から一定距離をおいて小さくすることにより、接続管６が熱影響により再圧入されても吸入孔５との接触長さが一定に保たれる為、荷重の増大を防止する事ができる。または吸入孔５内径を外周から一定距離をおいて拡げ拡げる事により上記同様接触長さを一定に保つ構成にしている。また圧入による密封では無く、吸入孔５にシール部材９を配する事により、圧入荷重自体をかけない構成にしている。更に、第二圧縮機構部３側の接続管６及び接続外管７を長くし、溶接部を容器１よる遠ざける事により熱影響を軽減している。   In order to solve the above-described problem, the present invention reduces the press-fit outer diameter of the upper or lower or lower connection pipe 6 at a certain distance from the tip, so that the connection pipe 6 can be re-pressed due to thermal effects. Since the contact length with the suction hole 5 is kept constant, an increase in load can be prevented. Alternatively, the inner diameter of the suction hole 5 is expanded from the outer periphery at a constant distance, so that the contact length is kept constant as described above. In addition, the sealing member 9 is arranged in the suction hole 5 instead of the press-fitting, so that the press-fitting load itself is not applied. Furthermore, the connection pipe 6 and the connection outer pipe 7 on the second compression mechanism part 3 side are lengthened, and the influence of heat is reduced by moving the welded part away from the container 1.

本発明の多気筒圧縮機は、気液分離器溶接時の熱影響による圧縮機構部へのダメージを軽減し、信頼性の高い圧縮機を提供することができる。   The multi-cylinder compressor of the present invention can reduce damage to the compression mechanism due to the heat effect during gas-liquid separator welding, and can provide a highly reliable compressor.

本願第１の発明は、密閉容器内部に溶接固定された第一の圧縮機構部と、その下部にボルトで締結固定された第二の圧縮機後部を配置し、両圧縮機構部に設けた吸入孔には、容器外部に配した気液分離器と接続される接続管が密閉容器に配した穴を通じて挿入固定され、かつ前記接続管の外周には一方を密閉容器穴と他方を気液分離器に溶接固定された接
続外管を有する二気筒圧縮機において、上下または、下側の接続管の圧入部外径を先端から一定距離をおいて小さくする事により、熱影響により接続管が吸入孔に再圧入されても接続管と吸入孔との接触長さは一定に保たれる為、過大な圧入荷重の発生を回避できる。 1st invention of this application arrange | positions the 1st compression mechanism part fixed by welding inside the airtight container, and the 2nd compressor rear part fastened and fixed by the volt | bolt in the lower part, and the suction provided in both compression mechanism parts In the hole, a connecting pipe connected to a gas-liquid separator arranged outside the container is inserted and fixed through a hole arranged in the hermetic container, and one of the outer circumference of the connecting pipe is a sealed container hole and the other is gas-liquid separated In a two-cylinder compressor having a connection outer pipe welded and fixed to the compressor, the connection pipe is sucked due to the heat effect by reducing the outer diameter of the press-fitting part of the upper or lower or lower connection pipe at a certain distance from the tip. Since the contact length between the connection pipe and the suction hole is kept constant even if re-pressed into the hole, it is possible to avoid an excessive press-fitting load.

第２の発明は、上下または下側の吸入穴内径を外周から一定距離をおいて拡げる事により第１の発明と同様の効果が得られる。   In the second invention, the same effect as that of the first invention can be obtained by expanding the inner diameter of the upper and lower or lower suction holes at a constant distance from the outer periphery.

第３の発明は、上下または下側の吸入穴と接続管の挿入部の間にシール部材を配する事により圧入による密封構造から、シール部材による密封に変更する事により、圧入荷重自体をかけない構成にし熱影響を回避することができる。   According to a third aspect of the present invention, a sealing member is arranged between the upper and lower or lower suction holes and the insertion portion of the connecting pipe, so that the press-fitting load itself is applied by changing the sealing structure by press-fitting to the sealing by the sealing member. It is possible to avoid the thermal effect with no configuration.

第４の発明は、ボルト締結にて固定された第二圧縮機構部側の接続管及び接続外管が、第一圧縮機構部側のものより長くする事により、溶接位置を第二圧縮機構部から遠ざける事により熱影響を軽減し、芯ずれの発生を回避している。   According to a fourth aspect of the present invention, the connecting pipe and the connecting outer pipe on the second compression mechanism part side fixed by bolt fastening are made longer than those on the first compression mechanism part side, whereby the welding position is set to the second compression mechanism part. By moving away from it, the thermal effect is reduced and the occurrence of misalignment is avoided.

第５の発明は、第１の発明または第２の発明のいずれかと、第４の発明を組み合わせる事により、更に溶接熱の影響を軽減する事ができる。   In the fifth aspect, the influence of welding heat can be further reduced by combining either the first aspect or the second aspect with the fourth aspect.

以下本発明の実施の形態について、図面を参照しながら説明する。なお、以下に記載する実施の形態により本発明が限定されるものではない。   Embodiments of the present invention will be described below with reference to the drawings. In addition, this invention is not limited by embodiment described below.

（実施の形態１）
図１は本発明第１の実施の形態における二気筒圧縮機を示す図である。 (Embodiment 1)
FIG. 1 is a diagram showing a two-cylinder compressor according to a first embodiment of the present invention.

密閉容器１の内部には、溶接固定された第一の圧縮機構部２と、その下部にボルト４で締結固定された第二の圧縮機後部３が配置されており、両圧縮機構部２，３には吸入孔５が設けられ、この吸入孔５には、接続管６が密閉容器1に配した穴を通じて挿入固定されている。接続管６は容器１外部にて、容器１穴に取り付けた接続外管７と共に、気液分離器８に溶接固定されている。本構造において、上下または、下側の接続管６の圧入部の外径形状を先端から一定距離をおいて小さくしている。これにより溶接時の長さ方向の伸縮からくる接続管６の位置ずれが発生した場合でも吸入孔５との接触長は一定に保つ事ができ、組立時の圧入荷重のバラツキを抑え、かつ熱影響により再圧入される状況が発生しても荷重の増大が回避できる。その結果、圧縮機構部２，３のメカ歪、芯ずれ等を防止でき、性能、信頼性の高い圧縮機を提供できる。   Inside the hermetic container 1, a first compression mechanism portion 2 fixed by welding and a second compressor rear portion 3 fastened and fixed by a bolt 4 are arranged below the first compression mechanism portion 2, and both compression mechanism portions 2, 3 is provided with a suction hole 5, and a connection pipe 6 is inserted into and fixed to the suction hole 5 through a hole provided in the sealed container 1. The connecting pipe 6 is welded and fixed to the gas-liquid separator 8 together with the connecting outer pipe 7 attached to the hole of the container 1 outside the container 1. In this structure, the outer diameter shape of the press-fitting portion of the upper and lower or lower connection pipes 6 is reduced at a certain distance from the tip. As a result, even when the displacement of the connecting pipe 6 resulting from the expansion and contraction in the length direction at the time of welding occurs, the contact length with the suction hole 5 can be kept constant, the variation of the press-fit load during assembly is suppressed, and the heat An increase in load can be avoided even if a re-pressed situation occurs due to the influence. As a result, mechanical distortion, misalignment, and the like of the compression mechanism units 2 and 3 can be prevented, and a compressor with high performance and reliability can be provided.

（実施の形態２）
図２は本発明第２の実施の形態における二気筒圧縮機を示す図である。 (Embodiment 2)
FIG. 2 is a view showing a two-cylinder compressor according to the second embodiment of the present invention.

図のように、上下または下側の吸入穴５の内径を外周から一定距離をおいて拡げた形状にしている。これにより実施の形態１同様、接続管６の位置がずれた場合でも吸入孔５との接触長は一定に保つ事ができ同様の効果を得る事ができる。   As shown in the figure, the inner diameter of the upper and lower or lower suction holes 5 is expanded at a certain distance from the outer periphery. Accordingly, as in the first embodiment, even when the position of the connecting pipe 6 is shifted, the contact length with the suction hole 5 can be kept constant, and the same effect can be obtained.

（実施の形態３）
図３は本発明第３の実施の形態における二気筒圧縮機を示す図である。 (Embodiment 3)
FIG. 3 shows a two-cylinder compressor according to the third embodiment of the present invention.

図のように、上下または下側の吸入穴５と接続管６の挿入部の間にシール部材９を配し密封している。これにより、圧入による荷重を排除する事ができる為、組立時の圧縮機構部へのダメージを防ぐ事ができる。   As shown in the figure, a sealing member 9 is disposed between the upper and lower or lower suction holes 5 and the insertion portion of the connecting pipe 6 for sealing. Thereby, since the load by press fit can be excluded, the damage to the compression mechanism part at the time of an assembly can be prevented.

（実施の形態４）
図４は本発明第４の実施の形態における二気筒圧縮機を示す図である。 (Embodiment 4)
FIG. 4 is a view showing a two-cylinder compressor according to the fourth embodiment of the present invention.

第二圧縮機構部３側の接続管６及び接続外管７が、第一圧縮機構部２側のものより長くなるよう構成している。これにより第２圧縮機構部３側の溶接位置を遠ざける事により、熱影響を低減し、かつ作業性の改善もはかることができる。   The connecting pipe 6 and the connecting outer pipe 7 on the second compression mechanism section 3 side are configured to be longer than those on the first compression mechanism section 2 side. Thereby, by moving away the welding position on the second compression mechanism portion 3 side, it is possible to reduce the thermal effect and improve workability.

（実施の形態５）
図５は本発明第５の実施の形態における二気筒圧縮機を示す図である。 (Embodiment 5)
FIG. 5 is a view showing a two-cylinder compressor in the fifth embodiment of the present invention.

実施の形態１または２のいずれかと、実施の形態４を組み合わせることにより、溶接時の接続管６の再圧入荷重の増大を防ぐと共に、熱源を遠ざける為、接続管６自体の位置ずれも低減でき更に圧縮機構部３へのダメージを低減することができる。   By combining either Embodiment 1 or 2 with Embodiment 4, it is possible to prevent an increase in the re-pressing load of the connection pipe 6 at the time of welding and reduce the displacement of the connection pipe 6 itself because the heat source is kept away. Furthermore, the damage to the compression mechanism part 3 can be reduced.

以上のように、本発明における多気筒圧縮機は、その大小に拘らず、あらゆる密閉形電動圧縮機に適用できる。   As described above, the multi-cylinder compressor according to the present invention can be applied to all hermetic electric compressors regardless of the size.
