面に取付け固定されるタイプが多用される。2. Description of the Related Art A commonly used air conditioner is configured by connecting an indoor unit installed in a room to be air-conditioned and an outdoor unit installed outside a building via a refrigerant pipe or the like. As the unit main body of the indoor unit, a type which is attached and fixed to a wall surface of a room to be air-conditioned is often used.

送風機５が収容配置される。As shown in FIG. 7, the indoor unit has a unit body 3 formed by a combination of a front panel 1 and a rear plate 2, and a heat exchanger 4 and a heat exchanger 4 are provided inside the unit body.
The blower 5 is accommodated and arranged.

態で対向する。As a recent trend, as shown in FIG. 1, the heat exchanger 4 is divided into a plurality of parts, and the heat exchanger 4 composed of a cross flow fan is bent around except for the rear plate 2 side. That is, the front panel 1 is opposed to the front panel 1 in a bent state over the front part and the upper part.
【０００５】上記前面パネル１には、熱交換器４と対向

に吹出し口６が形成される。[0005] The front panel 1 is provided with a suction port (not shown) in a front portion and an upper portion so as to face the heat exchanger 4. An outlet 6 is formed in the lower part of the front surface together with the end of the rear plate 2.

The lowermost portion is bent rearward, and the pipes are stored in the pipe storage section 8 on the back side.

なわち、普通は、ユニット本体３から延出される補助配
管９を、ユニット本体３の右側部から突出して外部配管
と接続するようになっているが、被空調室の壁面の都合
で左側部から突出して外部配管と接続せざるを得ない場
合がある。Due to such a configuration, there are many problems in workability particularly at the time of installation and maintenance of the indoor unit. That is, normally, the auxiliary pipe 9 extending from the unit main body 3 projects from the right side of the unit main body 3 and is connected to an external pipe. However, the auxiliary pipe 9 protrudes from the left side due to the wall surface of the room to be air-conditioned. Connection with external piping.
【０００８】右側取出し（右配管）の場合は、上記後板
２の下端部に形成される配管収納カバー８内に補助配管
９を収容してユニット本体３を据付け、この右側部から
突出する補助配管先端部と外部配管を接続すればよい。In the case of the right outlet (right pipe), the auxiliary pipe 9 is accommodated in a pipe storage cover 8 formed at the lower end of the rear plate 2 and the unit main body 3 is installed. What is necessary is just to connect a pipe front-end | tip part and external piping.
【０００９】ただし、左側取出し（左配管）の場合は、
補助配管９の先端部がユニット本体３の背面側に位置す
るため、ユニット本体３の背面で外部配管との接続作業
を行わなければならない。However, in the case of the left outlet (left piping),
Since the tip of the auxiliary pipe 9 is located on the back side of the unit main body 3, the connection work with the external pipe must be performed on the back side of the unit main body 3.
【００１０】そのため、接続作業時にはユニット本体３
の上部を据付け板１０に引っ掛け、下部を壁面から持ち
上げて隙間を作り、その隙間に手を入れて作業しなけれ
ばならなかった。[0010] Therefore, during the connection work, the unit body 3
Had to be hooked on the mounting plate 10 and the lower part lifted from the wall to create a gap, and the operator had to work by putting his hand in the gap.
【００１１】このようにして、特に左側取出しの場合
は、複雑で手間のかかる配管接続作業となるとともに、
上述したように被空調室壁面の高所での作業であるか
ら、不安定な姿勢で行うこととなり、極めて作業性が悪
い。In this way, especially in the case of taking out the left side, the pipe connection work becomes complicated and troublesome, and
As described above, since the work is performed at a high place on the wall surface of the room to be air-conditioned, the work is performed in an unstable posture, and the workability is extremely poor.

に付着した塵埃やカビを除去する作業がある。上記熱交
換器４に対する同作業は、前面パネル１を取外すことに
より熱交換器が露出するので、比較的容易に行える。On the other hand, there is an operation for removing dust and mold attached to the fan of the blower 5 together with the heat exchanger 4 at the time of maintenance which is preferably performed periodically. The same operation for the heat exchanger 4 can be performed relatively easily because the heat exchanger is exposed by removing the front panel 1.

ては配管に亀裂を生じさせて、冷媒をリークさせてしま
うこともあった。However, since the blower 5 is in a state of being surrounded and bent by the heat exchanger 4 except for the outlet ventilation passage 6, the ventilation passage is not large enough for a worker to access. 4 must be displaced to the extent that the blower 5 is exposed, which is a troublesome operation. In addition, when the heat exchanger 4 is displaced, the piping of the heat exchanger is deformed, and as a result, cracks occur in the piping. As a result, the refrigerant may leak.
【００１４】さらに、ユニット本体３を被空調室壁面に
取付け固定するのにあたって、あらかじめ同壁面に付属

ト本体を取付け固定するようになっている。Further, in mounting and fixing the unit main body 3 to the wall surface of the room to be air-conditioned, an attached mounting plate 10 is mounted and fixed in advance on the wall surface, and the unit main body is mounted and fixed to this mounting plate.

前面パネル１を掛止してユニット本体３が構成され、室
内ユニットの据付けがなされる。More specifically, the rear plate 2 on which the heat exchanger 4 and the blower 5 are arranged is mounted and fixed on the mounting plate 10, and the front panel 1 is hung on this rear plate to form the unit body 3, and the indoor unit is constructed. The unit is installed.

嵌め合いの関係で、前面パネルが後板から部分的に浮き

う。However, due to the fitting of the front panel 1 to the rear plate 2, the front panel is easily lifted partially from the rear plate, so that the engagement of the rear plate with the mounting plate 10 is weak, and the rear plate itself is partially. It will rise and deform.

These wind direction adjusting plates 11 are provided in drain pans 12a and 12b before and after receiving the drain water generated in the heat exchanger 4.

その作業が面倒である。In particular, since the rear drain pan 12b is provided integrally with the rear plate 2, there is no problem with this mounting workability.
The front drain pan 12a is separately manufactured and mounted. Moreover, the wind direction adjusting plate 11 is attached to the lower surface side of the front drain pan 12a and assembled, so that not only the drain pan itself is narrow in the depth direction but also obliquely inclined in accordance with the thin heat exchanger 4. Then, assembling the wind direction adjusting plate 11 composed of many parts here
That work is troublesome.

る。Even if the front panel 1 is removed during maintenance, the front drain pan 12a remains as it is,
Since the wind direction adjusting plate 11 remains provided on the drain pan, the operation via the outlet 11 is impossible.

に行える。Further, if the front panel 21 is removed, the wind direction adjusting section 40 integrated therewith is simultaneously removed. The heat exchanger 56 is exposed to remove dust and the like adhering to the heat exchanger 56. However, the heat exchanger 56 includes the front drain pan 57 of the rear plate 22 and the outlet ventilation passage 30 after the front panel 21 is removed. Since there is no obstacle in the opening A, the maintenance work for the blower fan 53 can be easily performed from here.
