Abstract

<P>PROBLEM TO BE SOLVED: To provide a hermetically sealed compressor constituting a refrigerant cycle wherein when strain caused in a cylinder at the time of brazing for an accumulator is diminished and a parts-count is reduced. <P>SOLUTION: The hermetically sealed compressor includes: a hermetically-sealed vessel 1; the accumulator; an external suction pipe 6 connecting the hermetically sealed vessel and the accumulator; a compression component 2 in the hermetically-sealed vessel 1; and an O-ring 4 in the compression component 2. An internal pipe 3 of the accumulator is inserted directly into the O-ring 4, and connection between the internal pipe 3 of the accumulator and the hermetically-sealed vessel 1 is made by welding 5. Thus, a brazing filler metal is eliminated, the strain is diminished, and the parts count is reduced. <P>COPYRIGHT: (C)2010,JPO&INPIT

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、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 connection pipe, and the accumulator is a suction outer pipe, a connection pipe, and a hermetic container. And was 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）。   Therefore, a method for reducing distortion during press-fitting and brazing of a connecting pipe by arranging an O-ring in the compression element is known (for example, see Patent Document 1).

しかし、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。この課題を解決するために、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方法が知られており、この方法ではアキュムレータ内管と密閉容器との接続をロー付けで行う手法が提案されている。
特開昭６１−１１８５７６号公報 However, in the structure in which the O-ring is arranged as described above, the number of parts increases, 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. . In order to solve this problem, a method is known in which the inner pipe length of the accumulator is extended and the inner pipe is directly inserted into the O-ring, so that no connection pipe is used. In this method, the accumulator inner pipe and the sealed container are A method of connecting with brazing has been proposed.
JP 61-118576 A

しかしながら、上述の方法ではフラックスを使用することが出来ないため、ロー付けによる接続が困難である。   However, since the flux cannot be used in the above-described method, connection by brazing is difficult.

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、アキュムレータ内管と密閉容器との接続を溶接にて行うことにより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, the hermetic compressor of the present invention can reduce the number of parts and reduce distortion by connecting the accumulator inner pipe and the hermetic container by welding.

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を密閉容器に溶接で接続することにより、フラックスや銀ローを無くし、使用材料量を減らすことが出来る。   In the first invention, by connecting the inner tube of the accumulator to the sealed container by welding, flux and silver solder can be eliminated, and the amount of material used 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. The present invention is not limited to the embodiments 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２に円形の溝が設けて有り、Ｏリング４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３をＯリング４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る。アキュムレータ内管３と密閉容器１の接続手法は従来ではロー付けで行う手法が提案されていた。しかし、ロー付けではフラックスを使用することが出来ないため接続が困難であった。本発明ではアキュムレータ内管３と密閉容器１の吸入外管６の接続を溶接で行うことにより、接続を可能にし、また使用材料を少なくした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 showing an embodiment of the present invention. In FIG. 1, a circular groove is provided in the compression element 2 and an O-ring 4 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 3 into the O-ring 4, it is possible to reduce the number of parts and reduce distortion. Conventionally, a method of connecting the accumulator inner tube 3 and the sealed container 1 by brazing has been proposed. However, since the flux cannot be used in brazing, connection is difficult. In the present invention, by connecting the accumulator inner tube 3 and the suction outer tube 6 of the sealed container 1 by welding, it is possible to provide a low-cost and highly reliable compressor that enables the connection and uses less material. I can do it.

以上のように、本発明における密閉型圧縮機は、部品点数削減と低歪化を実現することが出来、低コストかつ信頼性の高い密閉型圧縮機を提供することが出来る。   As described above, the hermetic compressor according to the present invention can realize a reduction in the number of parts and lower distortion, and can provide a hermetic compressor with low cost and high reliability.
