Description

本発明は、空気調和機等の冷凍装置に使用されるコンプレッサ用アキュムレータに関し、1シリンダ形だけでなく、2シリンダ形のコンプレッサに用いられるアキュムレータに関するものである。   The present invention relates to an accumulator for a compressor used in a refrigeration apparatus such as an air conditioner, and more particularly to an accumulator used in a two-cylinder type compressor as well as a one-cylinder type.

従来の圧縮機用アキュムレータの構造としては、図3、図4に示すように、上下の端に大きな丸みを持たせた絞り形状をもつ筒状密閉容器1と、その上部中央に冷媒を吸入する吸入管2、最下部より筒状密閉容器1を貫通し内部上方まで立ち上がる冷媒吐出用の吐出管3a、3bが設けられ、さらに吸入管2と吐出管3a、3b上端との間には、上側にメッシュ状で凸面形のフィルタ4と、下側に複数の孔6を有するバッフルプレート5が設けられている。   As shown in FIGS. 3 and 4, the conventional compressor accumulator has a cylindrical sealed container 1 having a throttle shape with large rounded upper and lower ends, and refrigerant is sucked into the center of the upper part thereof. The suction pipe 2 is provided with discharge pipes 3a and 3b for discharging refrigerant that penetrates the cylindrical sealed container 1 from the lowermost part and rises to the upper inside, and further, between the upper ends of the suction pipe 2 and the discharge pipes 3a and 3b, A mesh-shaped convex filter 4 and a baffle plate 5 having a plurality of holes 6 on the lower side are provided.

以上のような構造により筒状密閉容器1、上部中央の吸入管2より流入した冷媒は、フィルタ4により冷媒に混入しているゴミ等の異物が除去され、次にバッフルプレート5に当たり、バッフルプレート5に吐出管3a、3b上端の開口部3cを避けて設けられた孔6を通過することでガス冷媒と液冷媒に分離される。吐出管3a、3b上端の開口部3cにはガス冷媒のみが流入し、液冷媒は密閉容器1下部に溜まり、気化後に吐出管3a、3b開口部3cより流入される。   With the structure as described above, the refrigerant flowing in from the cylindrical sealed container 1 and the suction pipe 2 at the upper center is removed by foreign matter such as dust mixed in the refrigerant by the filter 4, and then hits the baffle plate 5. 5 is separated into a gas refrigerant and a liquid refrigerant by passing through a hole 6 provided avoiding the opening 3c at the upper end of the discharge pipes 3a and 3b. Only the gas refrigerant flows into the opening 3c at the upper ends of the discharge pipes 3a and 3b, and the liquid refrigerant accumulates in the lower part of the hermetic container 1 and flows into the opening 3c of the discharge pipes 3a and 3b after vaporization.

図3の特許文献1に記載された多気筒圧縮機用アキュムレータでは、吐出管3a、3bが、筒状密閉容器1の中間部に設置された固定孔8を有する中間板7に挿入固定されている。   In the accumulator for a multi-cylinder compressor described in Patent Document 1 in FIG. 3, the discharge pipes 3 a and 3 b are inserted and fixed to an intermediate plate 7 having a fixing hole 8 installed in an intermediate part of the cylindrical hermetic container 1. Yes.

これにより、吐出管3a、3bは正確かつ容易に取り付けられ、吐出管3a、3bの傾きなどの恐れがなくなり、傾いたことにより発生する吐出管3a、3b上端の開口部3cとバッフルプレート5に設けられた孔6の位置がオーバーラップし、液冷媒を吸ってしまうというような液分離機能に悪影響を与えることがない。さらに吐出管3aと吐出管3bでの接触や、吐出管3a、3bの筒状密閉容器1内壁への接触により発生する異常音を防ぐことができる構成となっている。
特開2004−360622号公報
As a result, the discharge pipes 3a and 3b can be attached accurately and easily, and there is no fear of the inclination of the discharge pipes 3a and 3b. The position of the hole 6 provided overlaps and does not adversely affect the liquid separation function of sucking the liquid refrigerant. Furthermore, it is a structure which can prevent the abnormal sound which generate | occur | produces by the contact with the discharge pipe 3a and the discharge pipe 3b and the contact to the cylindrical airtight container 1 inner wall of the discharge pipes 3a and 3b.

しかしながら前記、特許文献1記載の多気筒圧縮機用アキュムレータでは、固定孔を有する、中間板という部品が追加で必要となり、中間板の部品追加によるコストアップおよび組み立て工数増という課題を有していた。   However, in the accumulator for a multi-cylinder compressor described in Patent Document 1, an additional component called an intermediate plate having a fixing hole is required, and there is a problem of increased costs and increased assembly man-hours due to the addition of the intermediate plate components. .

本発明は、前記従来の課題を解決するもので、従来のように部品点数を増やすことなく、吐出管を2点で支持することにより正確かつ容易に、吐出管の傾きを抑えることが出来るコンプレッサ用アキュムレータを提供することを目的としている。   The present invention solves the above-mentioned conventional problems, and can reduce the inclination of the discharge pipe accurately and easily by supporting the discharge pipe at two points without increasing the number of parts as in the prior art. It aims to provide an accumulator for use.

前記従来の課題を解決するために、本発明のコンプレッサ用アキュムレータは、バッフルプレートの中央に円柱型の凸形状部を設け、吐出管上端の開口部は凸形状部で挿入固定され、吐出管の上部領域側面に側面孔を設けた構成となっている。   In order to solve the above conventional problems, the compressor accumulator of the present invention is provided with a cylindrical convex portion at the center of the baffle plate, and the opening at the upper end of the discharge pipe is inserted and fixed by the convex portion. A side hole is provided on the side of the upper region.

これによって、部品点数を増やすことなく、吐出管を筒状密閉容器の最下部とバッフルプレートに設けられた円柱型の凸形状窪みの2点で支持することができ、正確かつ容易に、吐出管の傾きを抑えることができ、従来同様の液分離機能および吐出管の傾きによる接触での異常音発生を防ぐことができる。   As a result, the discharge pipe can be supported at the two points of the bottom of the cylindrical airtight container and the cylindrical convex depression provided in the baffle plate without increasing the number of parts. , And the occurrence of abnormal noise due to contact due to the liquid separation function and the inclination of the discharge pipe can be prevented.

本発明のコンプレッサ用アキュムレータは、前記構成を有し、部品点数を増やすことなく、従来同様な機能が果たせ、部品点数追加によるコストアップおよび組み立て工数増を低減することができる。   The compressor accumulator of the present invention has the above-described configuration, can perform the same function as before without increasing the number of parts, and can reduce the cost increase and the number of assembling steps due to the addition of the number of parts.

以下、本発明の実施の形態を、図面を参照しながら説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

一般的な、従来のアキュムレータ付き縦型2シリンダ形ロータリーコンプレッサにおいて、密閉容器内には、下方に回転により冷媒ガスを圧縮するロータリ式の圧縮要素と、上方にその圧縮要素を回転駆動する電動要素とを配置しており、アキュムレータは、コンプレッサの密閉容器側壁に立てて配置され、アキュムレータは吸入される冷媒をガス冷媒と液冷媒に分離し、ガス冷媒を圧縮要素へ送りこんでいる。   In a conventional vertical two-cylinder rotary compressor with a conventional accumulator, a rotary compression element that compresses a refrigerant gas by rotating downward in an airtight container, and an electric element that rotationally drives the compression element upward The accumulator is arranged upright on the side wall of the hermetic container of the compressor, and the accumulator separates the refrigerant to be sucked into a gas refrigerant and a liquid refrigerant, and sends the gas refrigerant to the compression element.
