Description

密閉型圧縮機Hermetic compressor
　本発明は、空気調和機や冷蔵庫等の冷凍機器に用いる密閉型圧縮機に関する。 The present invention relates to a hermetic compressor used for refrigeration equipment such as an air conditioner and a refrigerator.
　密閉型圧縮機は、圧縮機本体とアキュムレータとを有する。アキュムレータは、圧縮機本体の吸込み側に、配管を介して接続される。アキュムレータにより、冷媒の中の液体成分が分離され、気体成分のみが圧縮機本体に吸い込まれる。圧縮機本体にアキュムレータを固定する構成としては、取り付けバンドとネジとを用いて、圧縮機本体に設けた金具とアキュムレータとを固定する構成がある。この構成の場合、圧縮機本体からの振動がアキュムレータに伝わるため、騒音が生じる。このため、従来の密閉型圧縮機は、圧縮機本体に設けた金具とアキュムレータとの間に、ゴムテープ等の緩衝材を挟む構成を有する。 The hermetic compressor has a compressor body and an accumulator. The accumulator is connected to the suction side of the compressor body via a pipe. The liquid component in the refrigerant is separated by the accumulator, and only the gas component is sucked into the compressor body. As a configuration for fixing the accumulator to the compressor main body, there is a configuration for fixing the metal fitting provided on the compressor main body and the accumulator using an attachment band and screws. In the case of this configuration, noise is generated because vibration from the compressor body is transmitted to the accumulator. For this reason, the conventional hermetic compressor has a configuration in which a cushioning material such as a rubber tape is sandwiched between a fitting provided on the compressor body and an accumulator.
　一方、圧縮機本体に設けた金具とアキュムレータとを、レーザ溶接等により固定した密閉型圧縮機がある。この構成の場合、取り付けバンドやネジが不要となるため、部品点数の削減および組み立て工数の削減を図ることができる。しかしながら、この構成では、緩衝材を用いることができない。つまり、この構成では、別途、騒音対策が必要である。例えば、図４に示す、特許文献１に開示されたアキュムレータ１０１は、底部付近に枠体１０２が圧入される。枠体１０２によって、アキュムレータ１０１の剛性が上がり、緩衝材を用いずに騒音が低減される。しかしながら、上記従来の構成では、騒音の低減は充分ではなかった。 On the other hand, there is a hermetic compressor in which metal fittings and accumulators provided in the compressor body are fixed by laser welding or the like. In the case of this configuration, an attachment band and a screw are not necessary, so that it is possible to reduce the number of parts and the number of assembly steps. However, in this configuration, a cushioning material cannot be used. In other words, this configuration requires a separate noise countermeasure. For example, in the accumulator 101 disclosed in Patent Document 1 shown in FIG. 4, the frame body 102 is press-fitted near the bottom. The frame 102 increases the rigidity of the accumulator 101 and reduces noise without using a cushioning material. However, in the conventional configuration, noise reduction is not sufficient.

　本発明は、アキュムレータと圧縮機本体とを溶接によって固定すると共に、騒音を低減した密閉型圧縮機を提供する。本発明に係る密閉型圧縮機は、内部にバッフルを有するアキュムレータと、アキュムレータを固定するための金具を有する圧縮機本体とを備える。さらに本発明に係る密閉型圧縮機は、アキュムレータと金具とは溶接により固定され、バッフルと金具とは、アキュムレータの外郭を介して互いに側方に位置する。 The present invention provides a hermetic compressor in which an accumulator and a compressor main body are fixed by welding and noise is reduced. The hermetic compressor according to the present invention includes an accumulator having a baffle therein and a compressor body having a metal fitting for fixing the accumulator. Furthermore, in the hermetic compressor according to the present invention, the accumulator and the metal fitting are fixed by welding, and the baffle and the metal fitting are located on the sides of each other through the outer shell of the accumulator.
　この構成によって、金具の側方でのアキュムレータの剛性が高まる。従って、圧縮機本体から金具を介して伝わる振動が減衰し、騒音が低減する。 This configuration increases the rigidity of the accumulator on the side of the bracket. Therefore, the vibration transmitted from the compressor body via the metal fitting is attenuated, and noise is reduced.

　（実施の形態１）
　図１は、本発明の実施の形態１における密閉型圧縮機の断面図である。図１において、密閉型圧縮機６は、圧縮機本体７とアキュムレータ１とを有する。アキュムレータ１の内部には、バッフル２が圧入またはロウ付けによって取り付けられる。また、バッフル２には、管５が圧入またはロウ付けによって取り付けられる。管５は冷媒の通路であり、冷媒は管５を通って圧縮機本体７に入る。圧縮機本体７には、金具３が設けられる。アキュムレータ１は、圧縮機本体７の金具３に、レーザ溶接等によって固定される。ここで、バッフル２の、アキュムレータ外郭８を介した側方には、金具３が位置する。つまり、バッフル２と金具３とは、高さ方向（図１において上下方向）に、アキュムレータ外郭８を介して少なくとも一部が重なり合う位置に構成される。 (Embodiment 1)
FIG. 1 is a cross-sectional view of a hermetic compressor according to Embodiment 1 of the present invention. In FIG. 1, the hermetic compressor 6 includes a compressor body 7 and an accumulator 1. A baffle 2 is attached inside the accumulator 1 by press-fitting or brazing. A tube 5 is attached to the baffle 2 by press-fitting or brazing. The pipe 5 is a refrigerant passage, and the refrigerant enters the compressor body 7 through the pipe 5. The compressor body 7 is provided with a metal fitting 3. The accumulator 1 is fixed to the metal fitting 3 of the compressor body 7 by laser welding or the like. Here, the metal fitting 3 is located on the side of the baffle 2 through the accumulator shell 8. That is, the baffle 2 and the metal fitting 3 are configured at a position where at least a part thereof overlaps with the accumulator shell 8 in the height direction (vertical direction in FIG. 1).
　以上のように構成された密閉型圧縮機６について、動作および作用を説明する。圧縮機本体７のモータ４が回転することにより生じる振動は、金具３を介してアキュムレータ１に伝わる。金具３の、アキュムレータ外郭８を介した側方にはバッフル２があるため、この部分でのアキュムレータ１の剛性は高い。従って、金具３から伝わる圧縮機本体７の振動は減衰される。つまり、アキュムレータ１の騒音が低減される。 The operation and action of the hermetic compressor 6 configured as described above will be described. Vibration generated by the rotation of the motor 4 of the compressor body 7 is transmitted to the accumulator 1 through the metal fitting 3. Since there is a baffle 2 on the side of the metal fitting 3 through the accumulator shell 8, the rigidity of the accumulator 1 at this portion is high. Therefore, the vibration of the compressor body 7 transmitted from the metal fitting 3 is attenuated. That is, the noise of the accumulator 1 is reduced.
　図２は、本実施の形態の構成による騒音の低減を示す説明図である。図２は、横軸である各周波数成分における騒音レベルを縦軸に示す。折れ線は、バッフル２を設けない構成における騒音レベルを示す。棒状のグラフは、本実施の形態のバッフル２を設けた構成における騒音レベルを示す。 FIG. 2 is an explanatory diagram showing noise reduction by the configuration of the present embodiment. FIG. 2 shows the noise level at each frequency component on the horizontal axis on the vertical axis. A broken line indicates a noise level in a configuration in which the baffle 2 is not provided. The bar graph shows the noise level in the configuration provided with the baffle 2 of the present embodiment.
　図２に示すように、周波数成分が２．０ｋＨｚから５．０ｋＨｚの範囲において、本実施の形態のバッフル２を設けた構成は、バッフル２を設けない構成と比較して、騒音レベルが低い。つまり、本実施の形態のバッフル２を設けた構成によって、図２において丸で囲み、斜線を掛けた分だけ騒音が低減される。なお、圧縮機本体７の全周囲の８方向において、Ａ特性周波数重み付け音圧レベル（つまり、ＪＩＳ　Ｃ　１５０９に規定されるＡ特性の騒音レベル）は、本実施の形態のバッフル２を設けた構成では、平均５８．５ｄＢ（Ａ）であり、バッフル２を設けない構成では、平均６０．３ｄＢ（Ａ）である。従って、本実施の形態のバッフル２を設けることにより、騒音が約２ｄＢ低減される。 As shown in FIG. 2, in the frequency component range of 2.0 kHz to 5.0 kHz, the configuration provided with the baffle 2 of the present embodiment has a lower noise level than the configuration provided with no baffle 2. That is, with the configuration provided with the baffle 2 of the present embodiment, noise is reduced by the amount circled in FIG. 2 and shaded. The A characteristic frequency weighted sound pressure level (that is, the A characteristic noise level defined in JIS C 1509) is provided in the eight directions around the compressor body 7 in the configuration in which the baffle 2 of the present embodiment is provided. Then, the average is 58.5 dB (A), and in the configuration without the baffle 2, the average is 60.3 dB (A). Therefore, by providing the baffle 2 of the present embodiment, noise is reduced by about 2 dB.
　以上述べたように、バッフル２と金具３とを、アキュムレータ外郭８を介して互いに側方に位置する構成（つまり、バッフル２と金具３とを、高さ方向に、アキュムレータ外郭８を介して少なくとも一部が重なり合う位置に構成）することにより、騒音が低減する効果を有する。従って、本実施の形態の密閉型圧縮機６は、圧縮機本体７とアキュムレータ１とを、金具３を用いて溶接により固定し、かつ、騒音が低減される。つまり、取り付けバンドやネジを用いずに密閉型圧縮機６を構成することができる。このため、部品点数が削減され、密閉型圧縮機６が簡素な構成となる。また、密閉型圧縮機６の組み立て工数の削減を図ることができる。 As described above, the structure in which the baffle 2 and the metal fitting 3 are positioned laterally with respect to each other via the accumulator outer shell 8 (that is, the baffle 2 and the metal fitting 3 are arranged at least via the accumulator outer shell 8 in the height direction). By configuring in a partly overlapping position, noise can be reduced. Therefore, in the hermetic compressor 6 of the present embodiment, the compressor main body 7 and the accumulator 1 are fixed by welding using the metal fitting 3, and noise is reduced. That is, the hermetic compressor 6 can be configured without using attachment bands or screws. For this reason, the number of parts is reduced, and the hermetic compressor 6 has a simple configuration. Further, the number of assembling steps for the hermetic compressor 6 can be reduced.
　なお、アキュムレータ１は、内部の構成によっては、管５の高さがバッフル２の位置より低い場合や、バッフル２に管５を圧入またはロウ付けすることが困難な場合がある。この場合は、図３に示すように、管５がバッフル２に固定されない構成とすることができる。この構成においても、同様の騒音低減の効果を有するため、本実施の形態は、この様なアキュムレータ１においても有用である。 Depending on the internal configuration of the accumulator 1, the height of the tube 5 may be lower than the position of the baffle 2, or it may be difficult to press-fit or braze the tube 5 into the baffle 2. In this case, as shown in FIG. 3, the tube 5 can be configured not to be fixed to the baffle 2. Since this configuration also has the same noise reduction effect, the present embodiment is also useful in such an accumulator 1.
　以上のように、本発明は、簡素な構成でありながら騒音が低減されるため、空気調和機や冷蔵庫等の冷凍機器に用いる密閉型圧縮機として利用可能である。 As described above, the present invention can be used as a hermetic compressor for use in refrigeration equipment such as an air conditioner and a refrigerator because noise is reduced with a simple configuration.
