Description
本発明は、冷凍機、空調機などに使用される密閉型圧縮機の改良に関するものである。 The present invention relates to an improvement of a hermetic compressor used for a refrigerator, an air conditioner and the like.
従来、この種の密閉型圧縮機は図３に主要部断面図を示すように、密閉容器と、アキュムレータと、吸入外管と、密閉容器内の圧縮要素と、接続管を備えており、前記アキュムレータは吸入外管、接続管、密閉容器によりシールされ圧縮要素と接続されていた。 Conventionally, this type of hermetic compressor includes a hermetic container, an accumulator, a suction outer pipe, a compression element in the hermetic container, and a connecting pipe, as shown in a sectional view of the main part in FIG. The accumulator was sealed by a suction outer tube, a connecting tube and a sealed container and connected to the compression element.
この方法ではアキュムレータ、圧縮要素、吸入外管、接続管のシールはロー付けで行われているため、ロー付け時の熱の影響で圧縮要素に歪が発生してしまうという問題があった。 In this method, since the accumulator, the compression element, the suction outer pipe, and the connection pipe are sealed by brazing, there is a problem in that the compression element is distorted by the influence of heat during brazing.
そのため、圧縮要素内にＯリングを配置することにより、接続管の圧入及びロー付け時の歪を低減する方法が知られている（例えば、特許文献１参照）。
しかしながら、上述したようなＯリングを配置する構造では、部品点数が増えると共に、圧縮要素にもＯリングを配置するための追加工をする必要が有り、結果として圧縮機のコストアップを招いていた。 However, in the structure in which the O-ring is arranged as described above, the number of parts is increased, and it is necessary to perform an additional process for arranging the O-ring on the compression element, resulting in an increase in the cost of the compressor. .
本発明は、上述した問題点を解決するためになされたものであり、冷媒吸入部の部品点数削減と圧縮要素の低歪化を図ることにより、低コストかつ高信頼性な圧縮機を提供することを目的とする。 The present invention has been made to solve the above-described problems, and provides a low-cost and highly-reliable compressor by reducing the number of parts of the refrigerant suction portion and reducing the distortion of the compression element. For the purpose.
前記従来の課題を解決するために、本発明の密閉型圧縮機は、アキュムレータの内管長を伸ばし、内管を直接Ｏリングに挿入することにより、接続管を使用しない密閉型圧縮機を提供する。本構成によって、部品点数の削減と共に低歪化を実現することが出来る。 In order to solve the above conventional problems, a hermetic compressor according to the present invention provides a hermetic compressor that does not use a connecting pipe by extending the inner pipe length of the accumulator and directly inserting the inner pipe into an O-ring. . With this configuration, it is possible to reduce the number of parts and reduce distortion.
本発明の密閉型圧縮機は、部品点数と圧縮機要素での歪を低く抑え、低コストかつ高信頼性な圧縮機を提供することができる。 The hermetic compressor of the present invention can provide a low-cost and highly-reliable compressor by suppressing the number of parts and distortion in the compressor element.
第１の発明は、アキュムレータの内管長を伸ばすと共に、圧縮要素内にＯリングを配置することにより、部品点数の削減と低歪化を実現することが出来る。 According to the first aspect of the present invention, it is possible to reduce the number of parts and reduce distortion by extending the inner pipe length of the accumulator and arranging an O-ring in the compression element.
第２の発明は、アキュムレータの内管を鉄製とし、銅メッキを施すことから、材料コストを削減することが出来る。 In the second invention, the inner tube of the accumulator is made of iron and is subjected to copper plating, so that the material cost can be reduced.
第３の発明は、アキュムレータの内管を鉄製とし、銅メッキをしないことから材料コストを削減することが出来る。 In the third invention, the inner tube of the accumulator is made of iron and is not plated with copper, so that the material cost can be reduced.
第４の発明は、密閉容器のバーリングを立て、吸入外管を無くすことで、部品点数を削減すことが出来る。 In the fourth invention, the number of parts can be reduced by raising the burring of the sealed container and eliminating the suction outer pipe.
第５の発明は、アキュムレータと密閉容器とのロー付けを低温ロー付けすることで、圧縮要素への熱影響を減らすことが出来る。 5th invention can reduce the thermal influence on a compression element by brazing low temperature brazing of an accumulator and an airtight container.
第６の発明は、アキュムレータと密閉容器とのロー付け時の加熱を誘導加熱方式とすることで、限られた狭い範囲を加熱し、圧縮要素への熱影響を減らすことが出来る。 In the sixth aspect of the invention, the heating at the time of brazing between the accumulator and the closed container is an induction heating method, so that a limited narrow range can be heated and the thermal influence on the compression element can be reduced.
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。 Hereinafter, embodiments of the present invention will be described 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、本発明の一実施例を示す密閉型圧縮機の主要部を示すものである。図１において、圧縮要素に円形の溝が設けて有り、Ｏリングが挿入されている。従来では接続管を通してアキュムレータ内管が圧縮要素に挿入されていた。本発明において、アキュムレータ内管をＯリングに直接挿入することにより、部品点数削減と低歪化を実現することが出来、低コストかつ高信頼性な圧縮機を提供することが出来る。
(Embodiment 1)
FIG. 1 shows a main part of a hermetic compressor according to an embodiment of the present invention. In FIG. 1, the compression element is provided with a circular groove and an O-ring is inserted. Conventionally, the accumulator inner tube is inserted into the compression element through the connecting tube. In the present invention, by directly inserting the accumulator inner tube into the O-ring, the number of parts and the distortion can be reduced, and a low-cost and highly reliable compressor can be provided.
（実施の形態２）
図２は、本発明の一実施例を示す密閉型圧縮機の主要部を示すものである。図２において、密閉容器のバーリングを大きくすることにより、吸入外管を無くし、部品点数を削減することから低コストである圧縮機を提供することが出来る。
