[Constitution] At the bottom of the dome 1, an intake pipe 10 for removing water 6 and foreign matter 7 accumulated on the inner bottom of the dome 1 is attached,
An on-off valve 11 is provided in the intake pipe 10.
Description
【０００１】[0001]
本考案は空気調和機、冷凍装置等の冷媒回路に組み込まれるアキュムレ−タに 関する。 The present invention relates to an accumulator incorporated in a refrigerant circuit of an air conditioner, a refrigerating device or the like.
【０００２】[0002]
従来のアキュムレ−タの１例が図２に示されている。 図２において、１はドーム、２はＵ字管、３は吸入管、４はＵ字管２の下部に 穿設されたオイルピックアップ穴、５はドーム１内に貯溜された液冷媒及び潤滑 油である。 An example of a conventional accumulator is shown in FIG. In FIG. 2, 1 is a dome, 2 is a U-shaped pipe, 3 is a suction pipe, 4 is an oil pickup hole formed in the lower portion of the U-shaped pipe, and 5 is a liquid refrigerant and lubricating oil stored in the dome 1. Is.
【０００３】 空気調和機の運転時、図示しない蒸発器で蒸発したガス冷媒が冷媒配管８、吸 入管３を経てドーム１内に入り、ここでガス冷媒に随伴する液冷媒、水分、異物 等が分離され、これらはドーム１内底部に落下してここに貯溜される。ガス冷媒 はＵ字管２にその入口2aから流入し、Ｕ字管２内を通り冷媒配管９を経て図示し ない圧縮機に吸い込まれる。 ドーム１内底部に貯溜された液冷媒や潤滑油５はオイルピックアップ穴４から 小量づつＵ字管２に入り、Ｕ字管２内を流過するガス冷媒に伴われて圧縮機に戻 る。During operation of the air conditioner, the gas refrigerant vaporized by an evaporator (not shown) enters the dome 1 through the refrigerant pipe 8 and the suction pipe 3, where liquid refrigerant, moisture, foreign matters and the like accompanying the gas refrigerant are collected. They are separated, and they fall to the inner bottom of the dome 1 and are stored there. The gas refrigerant flows into the U-shaped pipe 2 through its inlet 2a, passes through the U-shaped pipe 2 and is drawn into a compressor (not shown) through a refrigerant pipe 9. A small amount of liquid refrigerant or lubricating oil 5 stored in the bottom of the dome 1 enters the U-shaped pipe 2 from the oil pickup hole 4, and returns to the compressor along with the gas refrigerant flowing through the U-shaped pipe 2. .
【０００４】[0004]
空気調和機を据え付けた後、これを試運転すると、据付工事中に冷媒配管内に 紛れ込んだ水６や切粉、土砂、塵埃等の異物７がアキュムレ−タのドーム１内に 入って、その底部に溜り込むが、従来はこれを回収することができなかったため 、これら水６や異物７が液冷媒や潤滑油に伴われてオイルピックアップ穴４、Ｕ 字管２、冷媒配管８を経て圧縮機内に入り、圧縮機の故障を惹起するという不具 合があった。 After installing the air conditioner and performing a trial run, water 6 and foreign matter 7 such as cutting chips, earth and sand, and dust that had been mixed into the refrigerant pipe during the installation work entered the dome 1 of the accumulator and the bottom part It collects in the compressor, but since it could not be collected in the past, these water 6 and foreign matter 7 are accompanied by the liquid refrigerant and lubricating oil, and then pass through the oil pickup hole 4, the U-shaped pipe 2, and the refrigerant pipe 8 in the compressor. Then, there was a problem that it caused a failure of the compressor.
【０００５】[0005]
本考案は上記課題を解決するために提案されたものであって、その要旨とする ところは、ドームの底にこのドーム内底部に溜まった水分や異物を抜き取るため の摂取管を取り付け、この摂取管に開閉弁を介装したことを特徴とするアキュム レ−タにある。 The present invention has been proposed to solve the above-mentioned problems, and the gist of the present invention is to attach an intake pipe for extracting water and foreign matter collected at the bottom of the dome to the bottom of the dome. The accumulator is characterized in that an on-off valve is inserted in the pipe.
【０００６】[0006]
本考案においては、上記構成を具えているため、開閉弁を開とすることによっ てドーム内底部に滞留した水や異物は摂取管及び開閉弁を経て抜き取られる。 Since the present invention has the above-mentioned configuration, when the on-off valve is opened, water and foreign matter accumulated on the inner bottom of the dome are extracted through the intake pipe and the on-off valve.
【０００７】[0007]
本考案の１実施例が図１に示されている。 ドーム１の底にはドーム１内底部に溜まった水６や異物７を抜き取るための摂 取管10が取り付けられ、この摂取管10には開閉弁11が介装されている。 しかして、空気調和機の試運転終了後、開閉弁11を開とすれば、試運転時にド ーム１内底に溜まった水６や異物７は摂取管10及び開閉弁11を経て抜き出される 。抜き出した後、開閉弁11は閉とされる。 One embodiment of the present invention is shown in FIG. At the bottom of the dome 1, a water intake pipe 10 for removing water 6 and foreign matter 7 accumulated in the inner bottom of the dome 1 is attached, and an on-off valve 11 is provided in the intake pipe 10. Then, if the on-off valve 11 is opened after the trial run of the air conditioner, the water 6 and the foreign matter 7 accumulated on the inner bottom of the dome 1 during the trial run are extracted through the intake pipe 10 and the on-off valve 11. After extraction, the on-off valve 11 is closed.
【０００８】[0008]
本考案においては、開閉弁を開とすることによってドーム内底部に滞留した水 や異物を摂取管及び開閉弁を経て抜き取ることができるので、これら水や異物が ガス冷媒に伴われて圧縮機内に入ることによる圧縮機の故障を防止できる。 In the present invention, by opening the on-off valve, it is possible to drain the water and foreign matter staying at the bottom of the dome through the intake pipe and the on-off valve. It is possible to prevent breakdown of the compressor due to entry.
