Description

【0001】
【発明の属する技術分野】
本発明は、多気筒圧縮機に用いられるアキュムレータに関するものである。
【0002】
【従来の技術】
従来の多気筒圧縮機用アキュムレータは、図4に示すように、半球面を有する上部容器2と、同じく半球面を有する下部容器3を接続した円筒状の密閉容器1の上方に入口管4と、圧縮機(図示せず)と接続され前記密閉容器1の下部に設けられた複数の取付孔10a,10bから挿入された複数の出口管5a,5bと、この出口管5a,5bと前記入口管4との間に設置された複数の孔6を有する仕切板7とで構成されている(例えば特許文献1)。
【0003】
上記構成において、入口管4から流入した冷媒の液成分は、仕切板7に当たった後、この仕切板7に設けられた複数の孔6を通り、一旦、密閉容器1の下部へ溜まった後、気化してから出口管5a,5bよりガス成分として圧縮機へ流出する。
【0004】
【特許文献1】
特開平5―060080号公報
【0005】
【発明が解決しようとする課題】
しかしながら、上記従来の構成では、複数の出口管5a,5bは、密閉容器1の半球面状の下部に複数の取付孔10a,10bを設け、そこから密閉容器1内部に挿入したうえ、ロウ付けなどの方法によって設置固定されていた。
【0006】
特に、密閉容器1の径が比較的大きな場合には、この密閉容器1の下部と出口管5a,5bをロウ付けなどの方法によって設置固定された個所の強度が低下し、この密閉容器1の空間容積も広くなるために、これら出口管5a,5bが傾いた状態になりやすい。
【0007】
この複数の出口管5a,5bが傾いた状態になるような場合、密閉容器1の内部で、これら出口管5a,5bが互いに接触したり、あるいは密閉容器1の内壁に接触して異常音の原因となることがあった。
【0008】
さらに、場合によっては、出口管5a,5bの開口部が仕切板7に設けられた複数の孔6に直接のぞくことになり、入口管4から流入した冷媒の液成分がそのまま出口管5a,5bを経て圧縮機に吸入されるため、気液分離というアキュムレータ本来の機能を果たさず、圧縮機の信頼性を低下させるといった課題を生じていた。
【0009】
上記課題を解決する従来技術として、図5に示すように、特許文献1に開示されているアキュムレータが知られている。この技術によれば、アキュムレータの出口管101a,101bを入口管103側で先端を連結一体化した内管104にすることにより、互いの出口管101a,101bの倒れを防止するものである。
【0010】
しかしながら、上記従来技術では、出口管101a,bを入口管103側で連結一体化した内管104は、この出口管101a,101bを密閉容器102の内側から設置する必要があるために、出口管101a,101bと圧縮機とを接続するために、さらに別の接続管105が必要となっていた。
【0011】
本発明は、このような従来の課題を解決するものであり、密閉容器の径が比較的大きな場合でも、複数の出口管を二点支持により傾きのない多気筒圧縮機用アキュムレータを提供することを目的とする。
【0012】
【課題を解決するための手段】
上記課題を解決するために本発明は、前記中間板を下部容器に取り付けたものである。これにより、予め、この中間板の複数の固定孔に複数の出口管を挿入し固定することにより、出口管の傾きなどの恐れがなく、アキュムレータの径が比較的大きな場合でも、複数の出口管を傾きなく正確かつ容易に取り付けることができる。
【0013】
【発明の実施の形態】
上記課題を解決するために、請求項1に記載の発明は、密閉容器に、入口管と、圧縮機と接続され、前記密閉容器内部に挿入される複数の出口管と、これら出口管と前記入口管との間に複数の孔を有する仕切板とを設置し、複数の固定孔を有する中間板を前記下部容器内部に取り付け、その中間板の複数の固定孔に前記複数の出口管を挿入し固定したものである。そして、この構成により、中間板を下部容器に取り付け、複数の出口管を挿入し固定することにより、取り付け時にこれら出口管の傾きなどの恐れがなくなり、正確に取り付けることができる。
【0014】
以下、本発明の実施例について図面を参照して説明する。
【0015】
(実施の形態1)
図1は、本発明の実施の形態1における多気筒圧縮機用アキュームレータの図である。図1において、図2と図3および図4と同じ構成要素に関しては同じ符号を用い、説明を省略する。
【0016】
図1において、上部容器2と、下部容器3を接続した円筒状の密閉容器1の上方に入口管4と、圧縮機(図示せず)と接続された前記密閉容器1の内部に挿入される複数の出口管5a,5bと、これら出口管5a,5bと前記入口管4との間に複数の孔6を有する仕切板7とが設置されている。前記複数の出口管5a,5bは、固定孔9a,9bを有する中間板8に挿入し固定され、さらにこの中間板8が前記下部容器3に取り付けられている。
【0017】
上記構成において、入口管4から流入した冷媒の液成分は、仕切板7に当たった後、この仕切板7に設けられた複数の孔6を通り、一旦、密閉容器1の下部に溜まった後、気化してから出口管5a,5bよりガス成分として圧縮機へ流出する。
【0018】
前記固定孔9a,9bを有する中間板8を前記下部容器3に溶接等の方法によって取り付けられる。このとき、中間板8は、治具などを用いることにより取り付けられる。その後、出口管5a,5bを固定孔9a,9bに挿入し固定する事により、下部容器3の下部にロウ付けなどの方法により傾くことなく取り付けることができる。
【0019】
そのため、密閉容器1の径が比較的大きな場合でも、傾くことなく正確かつ容易に出口管5a,5bを設置することができる。
【0020】
これにより、密閉容器1の内部で、これら出口管5a,5bが互いに接触したり、密閉容器1の内壁に接触することで異常音の原因となったり、あるいは、出口管5a,5bの開口部が仕切板7に設けられた複数の孔6に直接のぞくことにより、入口管4から流入した冷媒の液成分がそのまま出口管5a,5bを経て圧縮機に吸入されるといったことはない。
【0021】
(実施の形態2)
図2は、本発明の実施の形態2における多気筒圧縮機用アキュームレータの図である。図2において、図1と図3および図4と同じ構成要素に関しては同じ符号を用い、説明を省略する。
【0022】
図2において、密閉容器1を、銅もしくは銅合金、好ましくはりん脱酸銅の材質とし、この密閉容器1と同じ径と厚さの円筒のそれぞれ上下を絞り加工によって一体成形している。
【0023】
これにより、密閉容器1を、上部容器2と下部容器3を接続して構成する必要がなくなり、より生産性を高めることができる。
【0024】
(実施の形態3)
図3は、本発明の実施の形態3における多気筒圧縮機用アキュームレータの図である。図3において、図1と図2および図4と同じ構成要素に関しては同じ符号を用い、説明を省略する。
【0025】
図3において、中間板8は、複数の固定孔9a,9bに加え、複数の開口部9cを構成している。
【0026】
入口管4から流入した冷媒の液成分が前記複数の開口部9cを通り、密閉容器1の下部に溜まる。その後、気化してから前記複数の開口部9cを通って出口管5a,5bよりガス成分として圧縮機へ流出する。
【0027】
これにより、複数の開口部9cは、冷媒の液成分とガス成分を通過させる事ができる。
【0028】
なお、上記実施の形態1および実施の形態2および実施の形態3では2気筒圧縮機用アキュムレータを用いて説明したが、本発明は、3気筒以上の圧縮機アキュムレータにおいても同様の効果が得られる。
【0029】
【発明の効果】
以上のように、請求項1記載の発明によれば、組立時、予め中間板を下部容器内部に取り付け、その後、複数の出口管を固定孔に挿入し固定してから密閉容器下部に取りつけるので、密閉容器の径が比較的大きな場合でも、傾くことなく正確かつ容易に出口管を設置することができる。
【0030】
したがって、密閉容器の内部で、これら出口管が互いに接触したり、密閉容器の内壁に接触したりすることにより、異常音が発生するようなことはない。また、出口管の開口部が仕切板に設けられた複数の孔に直接のぞくことにより、入口管から流入した冷媒の液成分がそのまま出口管を経て圧縮機に吸入され、圧縮機の信頼性を損なうといったことはない。
【0031】
以上、説明したように、本発明によれば、アキュムレータの径が比較的大きな場合でも、複数の出口管を傾くことなく正確かつ容易に取り付けられる生産性の高い多気筒圧縮機用アキュムレータを提供することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an accumulator used for a multi-cylinder compressor.
[0002]
[Prior art]
As shown in FIG. 4, a conventional multi-cylinder compressor accumulator includes an inlet pipe 4 above an upper container 2 having a hemispherical surface and a cylindrical hermetic container 1 connected to a lower container 3 also having a hemispherical surface. A plurality of outlet pipes 5a, 5b connected to a compressor (not shown) and inserted through a plurality of mounting holes 10a, 10b provided in the lower part of the closed vessel 1, and the outlet pipes 5a, 5b and the inlet And a partition plate 7 having a plurality of holes 6 provided between the tube 4 and the pipe 4 (for example, Patent Document 1).
[0003]
In the above configuration, the liquid component of the refrigerant flowing from the inlet pipe 4 hits the partition plate 7, passes through the plurality of holes 6 provided in the partition plate 7, and temporarily accumulates in the lower part of the closed container 1. After vaporizing, the gas flows out from the outlet pipes 5a and 5b as a gas component to the compressor.
[0004]
[Patent Document 1]
JP-A-5-060080 [0005]
[Problems to be solved by the invention]
However, in the above-described conventional configuration, the plurality of outlet pipes 5a and 5b are provided with a plurality of mounting holes 10a and 10b in a hemispherical lower portion of the closed container 1, and inserted into the closed container 1 from there, and then brazed. It was installed and fixed by such methods.
[0006]
In particular, when the diameter of the closed container 1 is relatively large, the strength of the portion where the lower portion of the closed container 1 and the outlet pipes 5a and 5b are installed and fixed by a method such as brazing decreases, and the closed container 1 Since the space volume is also widened, these outlet pipes 5a and 5b tend to be inclined.
[0007]
When the plurality of outlet pipes 5a and 5b are inclined, the outlet pipes 5a and 5b may contact each other inside the closed container 1 or may contact the inner wall of the closed container 1 to generate abnormal noise. May cause.
[0008]
Further, in some cases, the openings of the outlet pipes 5a and 5b may directly look into the plurality of holes 6 provided in the partition plate 7, and the liquid component of the refrigerant flowing from the inlet pipe 4 may be directly used as the outlet pipes 5a and 5b. Therefore, since the gas is sucked into the compressor after passing through the compressor, the original function of the accumulator, that is, gas-liquid separation, is not performed, and there has been a problem that the reliability of the compressor is reduced.
[0009]
As a conventional technique for solving the above-mentioned problem, an accumulator disclosed in Patent Document 1 is known as shown in FIG. According to this technique, the outlet pipes 101a, 101b of the accumulator are prevented from falling down by forming the outlet pipes 101a, 101b of the accumulator on the side of the inlet pipe 103, the inner pipe 104 being integrally connected.
[0010]
However, in the above-described conventional technique, the inner pipe 104 in which the outlet pipes 101a and 101b are connected and integrated on the inlet pipe 103 side requires the outlet pipes 101a and 101b to be installed from the inside of the closed vessel 102. In order to connect the compressors 101a and 101b and the compressor, another connection pipe 105 is required.
[0011]
The present invention is to solve such a conventional problem, and to provide an accumulator for a multi-cylinder compressor in which a plurality of outlet pipes are supported at two points and have no inclination even when the diameter of a closed container is relatively large. With the goal.
[0012]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the present invention is such that the intermediate plate is attached to a lower container. Thereby, by inserting a plurality of outlet pipes in advance into the plurality of fixing holes of the intermediate plate and fixing the outlet pipes, there is no danger of inclination of the outlet pipes, and even when the diameter of the accumulator is relatively large, the plurality of outlet pipes is provided. Can be accurately and easily attached without inclination.
[0013]

A plurality of outlet pipes 5a and 5b and a partition plate 7 having a plurality of holes 6 between the outlet pipes 5a and 5b and the inlet pipe 4 are provided. The plurality of outlet pipes 5a and 5b are inserted and fixed in an intermediate plate 8 having fixing holes 9a and 9b, and the intermediate plate 8 is attached to the lower container 3.
[0017]
In the above configuration, the liquid component of the refrigerant flowing from the inlet pipe 4 hits the partition plate 7, passes through the plurality of holes 6 provided in the partition plate 7, and temporarily accumulates in the lower portion of the closed container 1. After vaporizing, the gas flows out from the outlet pipes 5a and 5b as a gas component to the compressor.
[0018]
The intermediate plate 8 having the fixing holes 9a and 9b is attached to the lower container 3 by a method such as welding. At this time, the intermediate plate 8 is attached by using a jig or the like. Thereafter, the outlet pipes 5a, 5b are inserted into the fixing holes 9a, 9b and fixed, so that the outlet pipes 5a, 5b can be attached to the lower portion of the lower container 3 by a method such as brazing without tilting.

[0025]
In FIG. 3, the intermediate plate 8 has a plurality of openings 9c in addition to a plurality of fixing holes 9a and 9b.
[0026]
The liquid component of the refrigerant flowing from the inlet pipe 4 passes through the plurality of openings 9c and accumulates in the lower part of the closed container 1. Then, after vaporizing, it flows out of the outlet pipes 5a and 5b as a gas component to the compressor through the plurality of openings 9c.
[0027]
Thereby, the plurality of openings 9c can pass the liquid component and the gas component of the refrigerant.
[0028]
Although the first, second, and third embodiments have been described using the two-cylinder compressor accumulator, the present invention can provide the same effect in a three-cylinder or more compressor accumulator. .
[0029]
【The invention's effect】
As described above, according to the first aspect of the present invention, at the time of assembling, the intermediate plate is attached to the inside of the lower container in advance, and then a plurality of outlet pipes are inserted and fixed in the fixing holes and then attached to the lower portion of the closed container. Even when the diameter of the closed vessel is relatively large, the outlet pipe can be accurately and easily installed without tilting.
[0030]
Therefore, an abnormal noise does not occur when these outlet pipes come into contact with each other or inside wall of the closed container inside the closed container. In addition, by directly opening the opening of the outlet pipe into the plurality of holes provided in the partition plate, the liquid component of the refrigerant flowing from the inlet pipe is directly sucked into the compressor via the outlet pipe, thereby improving the reliability of the compressor. There is no loss.
