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. Further, an upper side is provided between the suction pipe 2 and the upper ends of 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 described above, the refrigerant flowing 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, 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 provided hole 6 overlaps and does not adversely affect the liquid separation function of sucking the liquid refrigerant. Furthermore, it is possible to prevent abnormal noise generated by contact between the discharge pipe 3a and the discharge pipe 3b and contact of the discharge pipes 3a and 3b with the inner wall of the cylindrical sealed container 1.

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8を有する、中間板7という部品が追加で必要となり、中間板7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, the accumulator for a multi-cylinder compressor described in Patent Document 1 requires an additional component called an intermediate plate 7 having a fixing hole 8, and there are problems of increased costs and increased assembly man-hours due to the additional components of the intermediate plate 7. Was.

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、吐出管上端の開口部をバッフルプレートに対し、傾斜して開口させ、開口部の一部分が挿入固定される、凸形状部を前記バッフルプレートの中央に設けた構成となっている。   In order to solve the above-mentioned conventional problems, an accumulator for a compressor according to the present invention has an opening at an upper end of a discharge pipe that is inclined with respect to a baffle plate, and a convex-shaped portion into which a part of the opening is inserted and fixed. It is the structure provided in the center of the said baffle plate.

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が果たせるとともに、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。   Thus, without increasing the number of parts, the discharge pipe can be supported at the two points of the bottom of the cylindrical sealed container and the convex depression provided in the baffle plate, and the inclination of the discharge pipe can be accurately and easily performed. Thus, it is possible to perform the same liquid separation function as before, and to prevent the generation of abnormal noise due to contact due to the inclination of the discharge pipe.

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 gas refrigerant and liquid refrigerant, and sends the gas refrigerant to the compression element.

(Embodiment 1)
FIG. 1 is a longitudinal sectional view of a compressor accumulator according to Embodiment 1 of the present invention. FIG. 2 is a diagram showing the positional relationship between the baffle plate and the upper end opening of the discharge pipe as viewed from the direction A in FIG.

図1、図2に示すように、筒状密閉容器1には、その上部には冷媒を吸入する吸入管2と、最下部より容器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を有し、さらに吸入管2と吐出管3a、3b上端との間には、上側にフィルタ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. 1 and 2, the cylindrical sealed container 1 includes a suction pipe 2 for sucking a refrigerant in an upper part thereof, and a discharge pipe 3 a for discharging a refrigerant that penetrates the container 1 from the lowermost part and rises up to the inside. Further, a baffle plate 5 having a filter 4 on the upper side and a plurality of holes 6 on the lower side is provided between the upper ends of the suction pipe 2 and the discharge pipes 3a and 3b.

吐出管3a、3b上端の開口部3cをバッフルプレート5に対し、傾斜して開口させ、バッフルプレート5に開口部3cの一部分が挿入固定される、凸形状部9を設けた構成としている。   An opening 3c at the upper end of the discharge pipes 3a, 3b is opened to be inclined with respect to the baffle plate 5, and a projecting portion 9 is provided in which a part of the opening 3c is inserted and fixed to the baffle plate 5.

かかる構成によれば、筒状密閉容器1の中間部に中間板7のような固定部を設けることなく、吐出管3a、3b上端の開口部3cの一部分がバッフルプレート5に挿入固定されることで、筒状密閉容器1の最下部での吐出管3a、3b固定が正確かつ容易にでき、管3a、3bの傾きを抑制することができる。   According to such a configuration, a part of the opening 3c at the upper end of the discharge pipes 3a and 3b is inserted and fixed to the baffle plate 5 without providing a fixing part such as the intermediate plate 7 in the intermediate part of the cylindrical sealed container 1. Thus, the discharge pipes 3a and 3b can be fixed accurately and easily at the lowermost part of the cylindrical sealed container 1, and the inclination of the pipes 3a and 3b can be suppressed.

これにより部品点数を増やすことなく、従来同様な液分離機能が果たせるとともに、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。   As a result, the same liquid separation function can be performed without increasing the number of parts, and the cost increase and the number of assembly steps due to the addition of the number of parts can be reduced.

なお前記、実施の形態の図1での吐出管3は、2本の2シリンダ形のタイプのものであるが、これに限定されるものではなく、吐出管3が1本の1シリンダ形のタイプの場合においても同様な効果作用を得ることができる。   In addition, although the discharge pipe 3 in FIG. 1 of the embodiment is of a two-cylinder type, the present invention is not limited to this, and the discharge pipe 3 has a single-cylinder type. Similar effects can be obtained in the case of the type.

また吐出管3a、3b上端の開口部3cの傾斜方向についても前記、実施の形態の図1に限定されるものではなく、どの方向であったとしても同様な効果作用を得ることができる。   Further, the inclination direction of the opening 3c at the upper end of the discharge pipes 3a and 3b is not limited to that in FIG. 1 of the embodiment, and the same effect can be obtained regardless of the direction.

本発明のコンプレッサ用アキュムレータは、1シリンダ形、2シリンダ形に関わらずアキュムレータを有する、あらゆるコンプレッサに適応が可能である。   The compressor accumulator of the present invention can be applied to any compressor having an accumulator regardless of the one-cylinder type or the two-cylinder type.
