Abstract
Description
【発明の詳細な説明】 本発明は密閉型圧縮機に係る。[Detailed description of the invention] The present invention relates to a hermetic compressor.
一般家庭用の冷凍・冷蔵庫に使用される密閉型圧縮機は
低騒音であることが要求される。Hermetic compressors used in general household freezers and refrigerators are required to have low noise.
そこで、圧縮機の騒音源の主原因の一つである吸込管か
ら密閉容器内に放射される音を減少させることを目的と
して、吸込側消音器が考えられている。Therefore, suction side mufflers have been considered for the purpose of reducing the sound radiated into the closed container from the suction pipe, which is one of the main sources of noise in the compressor.
ところが、冷凍・冷蔵庫は種々の型箔のものがあり、従
ってそれらに使用されている圧縮機も各種の容量のもの
があり、容量の異る圧縮機では吸込口で発生する騒音の
周波数が異る。従って、理論上は各機種毎に別異の吸込
側消音器を使用すべきではあるが、コスト上は複数機種
共通の消音器に機種毎に若干の改変を加えて使用するこ
とが好ましい。However, there are various types of refrigerators and freezers, and therefore the compressors used in them also have various capacities, and compressors of different capacities have different frequencies of noise generated at the suction port. Ru. Therefore, in theory, a different suction side muffler should be used for each model, but from a cost perspective, it is preferable to use a common muffler for multiple models with slight modifications for each model.

As shown in the figure, a forced-side silencing chamber 3 is provided on one side of the cylinder 2 that accommodates the piston 1 of the compressor, and a discharge-side silencing chamber 4 is provided on the other side. In general, a valve cover 6 having a partition wall 5 is provided on the inner shaft of the cylinder 2. Thus, a suction valve is provided inside the cylinder 2, and a discharge valve 8 is provided outside the cylinder 2, a suction pipe 9 is provided at the other end of the suction side muffling chamber 3, and a discharge pipe 10 is provided at the other end of the suction side muffling chamber 4. It is connected.

効果が得られないことがあった。However, there are limits to how much the silencing characteristics can be changed or adjusted by replacing the suction pipe 9, and a sufficient silencing effect may not be obtained depending on the type of compressor.
本発明は上記の事情に基きなされたもので、複数機種共

付けられている。In the embodiment shown in FIG. 2, the suction pipe 9 is attached to the upper part of the muffling chamber 3, and the resonance pipe 11, which is closed at one end, is attached to the lower part of the muffling chamber 3 so that its interior communicates with the interior of the chamber. In the embodiment of FIG. 3, the resonance chamber 12 is installed in a similar manner. In the embodiment shown in FIG. 4, an expansion chamber 13 is attached to the chamber 3, and the suction pipe 9 is attached to the expansion chamber.
