Description

【０００１】
【発明の属する技術分野】
本発明は分離形空気調和機の室外ユニットに関する。
【０００２】
【従来の技術】
従来の分離形空気調和機の１例が図３に示されている。
室外ユニット１を屋外に据え付け、室内ユニット２を室内に据え付けた後、サービスパネル７を取り外した状態で室内ユニット２からの液冷媒配管3a、ガス冷媒配管3bを操作弁4a、4bに接続し、制御信号線５を端子６に接続することによって室外ユニット１と室内ユニット２とは互いに連結される。
【０００３】
２台の室内ユニット２を１台の室外ユニット１に連結する場合には、図２に示されるように、液冷媒配管3aが接続される２個の液側操作弁4a及びガス冷媒配管3bが接続される２個のガス側操作弁4bはそれぞれ操作弁ブラケット９の取付面9aに螺子10によって固定されている。
【０００４】
【発明が解決しようとする課題】
上記従来の空気調和機においては、液冷媒配管3a、ガス冷媒配管3bを液側操作弁4a、ガス側操作弁4bと接続し又は取り外す際、各操作ナット4cを回さなければならないが、操作弁ブラケット９の取付面9aが平坦面とされているため、操作ナット4cと取付面9aとの距離が短く、メガネレンチを用いることができなかった。
従って、モンキーレンチやスパナを用いていたが、その回転角度が小さいので手間及び時間が掛かるという問題があった。
【０００５】
【課題を解決するための手段】
本発明は上記課題を解決するために発明されたものであって、その要旨とするところは、室内ユニットからの冷媒配管が接続される操作弁を設置する取付面が平坦面である操作弁ブラケットを備え、該操作弁ブラケットの上記取付面に操作ナットを有する上記操作弁を該操作ナットの軸心が上記取付面と平行になるよう設置してなる分離形空気調和機の室外ユニットにおいて、上記操作弁ブラケットの上記取付面における上記操作ナットに対応する部分に、上記操作弁の上記操作ナットと上記取付面との間に該操作ナットを回す工具が入る隙間を確保する矩形状の凹み部を反操作弁側へ突出させて一体形成したことを特徴とする分離形空気調和機の室外ユニットにある。
【０００６】
他の特徴とするところは、上記凹み部を少なくともメガネレンチが挿入可能な大きさに形成したことにある。
【０００７】
【発明の実施の形態】
本発明の実施形態が図１に示され、(A) は操作弁ブラケットの正面図、(B) は(A) のＢ−Ｂ線に沿う断面図である。
【０００８】
操作弁ブラケット９には各液側操作弁4a、ガス側操作弁4bの操作ナット4cに対応する部分に操作ナット4cとの隙間を確保する凹み部20が形成されている。
この凹み部20は少なくともメガネレンチが挿入可能な大きさとするのが望ましい。
他の構成は図２及び図３に示す従来のものと同様であり、対応する部材には同じ符号を付してその説明を省略する。
【０００９】
しかして、液冷媒配管3a、ガス冷媒配管3bを液側操作弁4a、ガス側操作弁4bに接続又は取り外す場合には、メガネレンチ、モンキーレンチ、スパナ等を凹み部20に入れて操作ナット4cを回せば良い。
この際、操作ナット4cと凹み部20の底面との隙間が大きいので、メガネレンチを用いることができ、また、モンキーレンチやスパナを用いた場合にはその回転角度を大きく採れるので操作ナット4cを容易、かつ、迅速に回すことができる。
【００１０】
【発明の効果】
本発明においては、操作弁ブラケットにこれと操作弁の操作ナットとの隙間を確保する凹み部を形成したため、室内ユニットからの冷媒配管を操作弁に接続又は取外す際、モンキーレンチやスパナを用いた場合にはその回転角度を大きく採れるので、操作ナットを容易、かつ、迅速に回すことができる。
【００１１】
凹み部を少なくともメガネレンチが挿入可能な大きさに形成すれば、メガネレンチを用いて操作ナットを回すことが可能となる。

BACKGROUND OF THE INVENTION
The present invention relates to an outdoor unit of a separation type air conditioner.
[0002]
[Prior art]
An example of a conventional separation type air conditioner is shown in FIG.
After the outdoor unit 1 is installed outdoors and the indoor unit 2 is installed indoors, the liquid refrigerant pipe 3a and the gas refrigerant pipe 3b from the indoor unit 2 are connected to the operation valves 4a and 4b with the service panel 7 removed. The outdoor unit 1 and the indoor unit 2 are connected to each other by connecting the control signal line 5 to the terminal 6.
[0003]
When two indoor units 2 are connected to one outdoor unit 1, as shown in FIG. 2, two liquid side operation valves 4a and gas refrigerant pipes 3b to which liquid refrigerant pipes 3a are connected are provided. The two gas side operation valves 4b to be connected are fixed to the mounting surface 9a of the operation valve bracket 9 by screws 10 respectively.
[0004]
[Problems to be solved by the invention]
In the conventional air conditioner, when connecting or removing the liquid refrigerant pipe 3a and the gas refrigerant pipe 3b with the liquid side operation valve 4a and the gas side operation valve 4b, each operation nut 4c must be turned. Since the mounting surface 9a of the valve bracket 9 is a flat surface, the distance between the operation nut 4c and the mounting surface 9a is short, and a spectacle wrench cannot be used.
Therefore, although the monkey wrench and spanner were used, there was a problem that it took time and effort because the rotation angle was small.
[0005]
[Means for Solving the Problems]
The present invention was invented to solve the above problems, and has as its gist operating valve mounting surface to install the operating valve to the refrigerant pipe from the chamber unit is connected to a flat surface In an outdoor unit of a separate type air conditioner, comprising a bracket, wherein the operation valve having an operation nut on the mounting surface of the operation valve bracket is installed so that the axis of the operation nut is parallel to the mounting surface . A rectangular recess that secures a gap between the operation nut and the mounting surface of the operation valve and a tool for turning the operation nut in a portion corresponding to the operation nut on the mounting surface of the operation valve bracket. In the outdoor unit of the separation-type air conditioner, which is integrally formed by protruding toward the counter-acting valve side .
[0006]
Another feature is that the recess is formed in a size that allows at least a spectacle wrench to be inserted.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention is shown in FIG. 1, (A) is a front view of an operation valve bracket, and (B) is a sectional view taken along line BB of (A).
[0008]
The operation valve bracket 9 is formed with a recess 20 that secures a clearance from the operation nut 4c at a portion corresponding to the operation nut 4c of each liquid side operation valve 4a and gas side operation valve 4b.
It is desirable that the recess 20 has a size that allows at least a spectacle wrench to be inserted.
The other structure is the same as that of the prior art shown in FIGS. 2 and 3, and the corresponding members are denoted by the same reference numerals and description thereof is omitted.
[0009]
Therefore, when connecting or removing the liquid refrigerant pipe 3a and the gas refrigerant pipe 3b to or from the liquid side operation valve 4a or gas side operation valve 4b, put a spectacle wrench, a monkey wrench, a spanner, etc. into the recess 20 and operate the operation nut 4c. Can be turned.
At this time, since the gap between the operation nut 4c and the bottom surface of the recess 20 is large, a spectacle wrench can be used, and when using a monkey wrench or spanner, the rotation angle can be taken large, so the operation nut 4c It can be turned easily and quickly.
[0010]
【The invention's effect】
In the present invention, since a recess is formed in the operation valve bracket to ensure a gap between the operation valve and the operation nut of the operation valve, a monkey wrench or spanner was used when connecting or removing the refrigerant pipe from the indoor unit to the operation valve. In such a case, since the rotation angle can be increased, the operation nut can be easily and quickly turned.
[0011]
If the recess is formed to have a size that allows at least the spectacle wrench to be inserted, the operation nut can be turned using the spectacle wrench.
[Brief description of the drawings]
1A and 1B show an embodiment of the present invention, in which FIG. 1A is a front view of an operating valve bracket, and FIG. 1B is a cross-sectional view taken along line BB in FIG.
FIGS. 2A and 2B show a conventional operation valve bracket, in which FIG. 2A is a front view, and FIG. 2B is a view taken along the line BB in FIG.
FIG. 3 is a perspective view of a conventional separation type air conditioner.
