FIG. 10 is a cross-sectional view of an external refrigerant pipe that is similarly connected to the indoor unit main body.

室内機本体は、図1、図2に示すように、後側に配置され、ケーシング1内のファン2を回転駆動するモータ8、前側に配置され、冷媒配管内の冷媒とファン2により通風される空気とを熱交換させる熱交換器3、熱交換器3から滴下するドレンを溜めるドレンパン5、熱交換器3の冷媒配管の先端部である冷媒配管接続部7、7及び冷媒配管接続部7、7からの滴下水を受けドレンパン5に流すドレン受部品4等を外箱6内に収容したものである。そして、外箱6の底部の開口は底板17で塞がれ、また、外箱6にはファン2の入口となる後側及び上側に設けられた吸込口及び出口となる前側に設けられた吹出口が設けられる。なお、図2の白抜きの矢印は、室内機本体の空気の吸込口及び吹出口を示す。
熱交換器3の液管及びガス管の2本の冷媒配管は、図示しない室外機本体に接続した外部冷媒配管9と接続される。この熱交換器3の冷媒配管と外部の外部冷媒配管9とは、熱交換器3の冷媒配管の先端部である2個の冷媒配管接続部7、7で接続される。
As shown in FIGS. 1 and 2, the indoor unit main body is disposed on the rear side, and is disposed on the front side of the motor 8 that rotationally drives the fan 2 in the casing 1, and is ventilated by the refrigerant and the fan 2 in the refrigerant pipe. The heat exchanger 3 for exchanging heat with the air to be collected, the drain pan 5 for collecting the drain dripping from the heat exchanger 3, the refrigerant pipe connection parts 7 and 7 and the refrigerant pipe connection part 7 which are the front ends of the refrigerant pipes of the heat exchanger 3 , 7 and the drain receiving part 4 and the like flowing into the drain pan 5 are received in the outer box 6. The opening at the bottom of the outer box 6 is closed by a bottom plate 17, and the outer box 6 has a suction port provided at the rear side and the upper side as an inlet of the fan 2 and a blower provided at a front side as an outlet. An exit is provided. In addition, the white arrow of FIG. 2 shows the air inlet and outlet of the indoor unit main body.
Two refrigerant pipes of the liquid pipe and the gas pipe of the heat exchanger 3 are connected to an external refrigerant pipe 9 connected to an outdoor unit body (not shown). The refrigerant pipe of the heat exchanger 3 and the external refrigerant pipe 9 outside are connected by two refrigerant pipe connecting portions 7 and 7 that are the front ends of the refrigerant pipe of the heat exchanger 3.

冷媒配管接続部7、7は、室内機本体内の熱交換器3側から外箱6の一部を構成する第1の外板6aを突出する冷媒配管の先端部として、第1の外板6aと同じく外箱6の一部を構成する第2の外板6bで形成された外箱6の切欠き部6Aに配置される。即ち、室内機本体の前部に設置された熱交換器3の後側で、右側に、上下方向に配置された第1の外板6aと、室内機本体の後部に設置されたファン2の右側部で、第1の外板6aの左端から直交して、後方に延設された第2の外板6bとで形成された外箱6の右後部の切欠き部6Aに、第1の外板6aを直交して突出する熱交換器3の冷媒配管の先端部である冷媒配管接続部7、7が2個並んで配置される。   The refrigerant pipe connection portions 7 and 7 are the first outer plate as a tip portion of the refrigerant pipe protruding from the first outer plate 6a constituting a part of the outer box 6 from the heat exchanger 3 side in the indoor unit body. It is arrange | positioned at 6 A of notches of the outer box 6 formed of the 2nd outer plate 6b which comprises a part of outer box 6 similarly to 6a. That is, on the rear side of the heat exchanger 3 installed at the front part of the indoor unit body, on the right side, the first outer plate 6a arranged in the vertical direction and the fan 2 installed at the rear part of the indoor unit body. On the right side, a first notch 6A on the right rear portion of the outer box 6 formed by a second outer plate 6b extending rearward and orthogonal to the left end of the first outer plate 6a Two refrigerant pipe connection parts 7 and 7 which are the front-end | tip parts of the refrigerant | coolant pipe | tube of the heat exchanger 3 which protrude at right angles to the outer plate 6a are arranged side by side.

2個の冷媒配管接続部7、7の位置関係は、2個の冷媒接続配管7、7を配管突出方向に第1の外板6aに投影した投影部が、左右方向に所定の間隔を有し、また、第2の外板6bに近い方が遠い方よりも所定量下となるようにされる。即ち、2個の冷媒配管接続部7、7は、左右に所定の間隔を開け、また、第2の外板6b寄りの冷媒配管接続部7が所定量だけ下となるように上下に間隔を開け、第1の外板6aに平行な面上で並んで配置される。そこで、室内機本体の背面側から見ると、図4、図6、図7に示すように右側を下とし左側を上とするように傾斜している。   The positional relationship between the two refrigerant pipe connecting portions 7 and 7 is such that the projection portion obtained by projecting the two refrigerant connecting pipes 7 and 7 onto the first outer plate 6a in the pipe protruding direction has a predetermined interval in the left-right direction. In addition, the distance closer to the second outer plate 6b is set to a predetermined amount lower than the distance farther away. That is, the two refrigerant pipe connection portions 7 and 7 are spaced apart from each other at a predetermined interval, and the refrigerant pipe connection portions 7 near the second outer plate 6b are spaced apart from each other by a predetermined amount. Open and arranged side by side on a plane parallel to the first outer plate 6a. Therefore, when viewed from the back side of the indoor unit main body, as shown in FIGS. 4, 6, and 7, it is inclined so that the right side is the bottom and the left side is the top.

冷媒配管接続部7、7の上方には、配管固定具取付部11を設け、この配管固定具取付部11に、冷媒配管接続部7、7に接続した外部冷媒配管9、9を配管固定具である配管固定板10及び配管押え16を使って固定する。配管固定具取付部11は、第1の外板6aと第2の外板6b上部から冷媒配管接続部7、7の上方に延設する。この配管固定具取付部11の底面は、冷媒配管接続部7、7の傾斜配置に従って、図4、図6、図7に示すように、室内機本体の背面側から見て、右側を下とし左側を上とするように傾斜して形成される。さらに、図5に示すように、配管固定具取付部11の底面は、後側から前側に向かって上昇するように傾斜して形成される。そこで、冷媒配管接続部7、7を上下方向に間隔を開け、また、傾斜配置とすることにより、冷媒配管接続部7、7に対して、室内機本体の右側面側及び下方(ドレンパン5、底板17、ドレン受部品4は取り外して行う)が開放され、外部冷媒配管の接続作業がやりやすくなる。また、接続後の外部冷媒配管9、9を固定する配管固定具を取付ける配管固定具取付部11の底面を同じく傾斜させているので、接続後の外部冷媒配管9、9の固定もやりやすくなる。更に、配管固定具取付部11の底面は、後側から前側に向かって上昇するように傾斜して形成されるので、冷媒配管接続部7、7と配管固定具取付部11の底面との間隔が広がり、冷媒配管接続部7、7での接続の際、ナット締め等の作業がやりやすくなる。
なお、図1等に示すように、冷媒配管接続部7、7は、第1の外板6aとの途中に支持板15を設置しているが、このようにすれば、冷媒配管接続部7、7はより安定して設置できる。
A pipe fixture attaching portion 11 is provided above the refrigerant pipe connecting portions 7 and 7, and external refrigerant pipes 9 and 9 connected to the refrigerant pipe connecting portions 7 and 7 are connected to the pipe fixture attaching portion 11. The pipe fixing plate 10 and the pipe presser 16 are fixed. The pipe fixture attachment portion 11 extends from the upper portions of the first outer plate 6a and the second outer plate 6b to above the refrigerant pipe connection portions 7, 7. As shown in FIGS. 4, 6, and 7, the bottom surface of the pipe fixing part 11 has a right side as viewed from the rear side of the indoor unit body as shown in FIGS. Inclined so that the left side is the top. Furthermore, as shown in FIG. 5, the bottom surface of the pipe fixture attachment portion 11 is formed to be inclined so as to rise from the rear side toward the front side. Then, the refrigerant | coolant piping connection parts 7 and 7 are spaced apart in the up-down direction, and are made into the inclination arrangement | positioning, By the refrigerant | coolant piping connection parts 7 and 7, the right side surface side of an indoor unit main body, and downward (drain pan 5, The bottom plate 17 and the drain receiving component 4 are removed), and the connection work of the external refrigerant pipe becomes easy. Moreover, since the bottom face of the pipe fixture attaching portion 11 for attaching the pipe fixture for fixing the external refrigerant pipes 9 and 9 after connection is similarly inclined, the external refrigerant pipes 9 and 9 after connection are easily fixed. . Furthermore, since the bottom surface of the pipe fixture attachment portion 11 is formed so as to rise from the rear side toward the front side, the distance between the refrigerant pipe connection portions 7 and 7 and the bottom surface of the pipe fixture attachment portion 11. When the refrigerant pipe connection portions 7 and 7 are connected, it is easy to perform operations such as nut tightening.
In addition, as shown in FIG. 1 etc., although the refrigerant | coolant piping connection parts 7 and 7 have installed the support plate 15 in the middle with the 1st outer plate 6a, if it carries out like this, the refrigerant | coolant piping connection part 7 will be provided. 7 can be installed more stably.

冷媒配管接続部7、7に接続した外部冷媒配管9、9を固定する際に使用する配管固定板10は、配管固定具取付部11の底面にネジ止め等で取付けられるが、片面側に凸部10a、反対の面側に凹部10bが形成され、外部冷媒配管9の外径の大きさにより使いわける。即ち、標準の外部冷媒配管9では凸部10a側が外側になるように取付けられ、断熱材を多くした径大の外部冷媒配管9に対しては、凹部10b側が外側になるように取付けられる。このようにして、2種類の径の異なる外部冷媒配管9に対して、接続時に、冷媒配管接続部7と外部冷媒配管9とのセンター合せを可能とする。図6は、配管固定板10を凸部10aを外側に取付けた標準配管用であり、図7は、凹部10bを外側に取付けた管径大用である。冷媒配管接続部7と配管固定板10との距離cが図7の方が図6より大となり、外径が大の高断熱用冷媒配管の接続及び固定が可能となる。冷媒配管接続部7、7に接続した外部冷媒配管9、9は、配管固定板10の面上に形成された2つの凸部又は凹部上で、図9に示すように配管押え16により配管固定板10に固定される。このように接続する外部冷媒配管9の外径により配管固定板10の凸部10aと凹部10bを使いわけることにより、後述の共通のドレン受け部品4が使用できる。
なお、図10は、外部冷媒配管9の断面図であるが、銅管13の外側に断熱材14が巻かれている。外部冷媒配管9には、標準用(一般用)と高断熱用があり、高断熱用は標準用(一般用)と比較すると、断熱材14が厚いため外径bが大きい。
The pipe fixing plate 10 used when fixing the external refrigerant pipes 9 and 9 connected to the refrigerant pipe connecting parts 7 and 7 is attached to the bottom surface of the pipe fixing part attaching part 11 with screws or the like, but protrudes to one side. A concave portion 10b is formed on the opposite side of the portion 10a and can be used depending on the outer diameter of the external refrigerant pipe 9. That is, the standard external refrigerant pipe 9 is attached so that the convex portion 10a side is on the outside, and the large-diameter external refrigerant pipe 9 having a large amount of heat insulating material is attached so that the concave portion 10b side is on the outside. In this way, when the external refrigerant pipes 9 having different diameters are connected, the refrigerant pipe connecting portion 7 and the external refrigerant pipe 9 can be centered. 6 is for standard piping with the convex portion 10a attached to the outer side of the pipe fixing plate 10, and FIG. 7 is for large pipe diameter with the concave portion 10b attached to the outer side. The distance c between the refrigerant pipe connection portion 7 and the pipe fixing plate 10 is larger in FIG. 7 than in FIG. 6, and connection and fixation of the highly heat-insulating refrigerant pipe having a large outer diameter is possible. The external refrigerant pipes 9, 9 connected to the refrigerant pipe connection parts 7, 7 are fixed on the pipe by the pipe presser 16 as shown in FIG. 9 on the two convex parts or concave parts formed on the surface of the pipe fixing plate 10. Fixed to the plate 10. By separately using the convex portion 10a and the concave portion 10b of the pipe fixing plate 10 depending on the outer diameter of the external refrigerant pipe 9 to be connected in this way, a common drain receiving component 4 described later can be used.
FIG. 10 is a cross-sectional view of the external refrigerant pipe 9, but a heat insulating material 14 is wound around the outside of the copper pipe 13. The external refrigerant pipe 9 has a standard (general) and a high heat insulation. Compared with a standard (general) high heat insulation, the heat insulating material 14 is thicker and the outer diameter b is larger.

図1に示すように、冷媒配管接続部7、7の下方にはドレン受部品4を設ける。ドレン受部品4は、配管接続部7、7を覆うカバーであり、上部及び熱交換器3側が開口し、熱交換器3と反対側に外部冷媒配管9の取出し用の2個の開口である外部冷媒配管9、9の通過口4a、4aを有し、熱交換器3寄り側ほどカバー深さが増すカバーである。そして、両側の上部を配管固定板取付部11にネジ止めにより取付ける。
このドレン受部品4は、図3に示すように、ドレンパン5に向かって傾斜し、取付により、先端部がドレンパン5上に配置される。そこで、冷媒配管接続部7、7の結露による水滴は、ドレン受部品4で受けドレンパン5に流すことができ、冷媒配管接続部7、7に断熱材を巻くというやっかいな作業をする必要がなくなる。
As shown in FIG. 1, a drain receiving component 4 is provided below the refrigerant pipe connection portions 7 and 7. The drain receiving part 4 is a cover that covers the pipe connection parts 7, 7. The upper part and the heat exchanger 3 side are open, and two openings for taking out the external refrigerant pipe 9 are provided on the side opposite to the heat exchanger 3. The cover has passage ports 4a and 4a for the external refrigerant pipes 9 and 9, and the cover depth increases toward the heat exchanger 3 side. And the upper part of both sides is attached to the pipe fixing plate attaching part 11 by screwing.
As shown in FIG. 3, the drain receiving component 4 is inclined toward the drain pan 5, and the tip is disposed on the drain pan 5 by mounting. Therefore, water droplets due to condensation on the refrigerant pipe connecting portions 7 and 7 can be flowed to the drain pan 5 by the drain receiving component 4, and there is no need to perform a troublesome work of winding a heat insulating material around the refrigerant pipe connecting portions 7 and 7. .

上記は、図1等に示すように、冷媒配管接続部7、7を室内機本体の右側後部の外箱6の切欠き部6Aに配置したが、左側後部に外箱6の切欠き部6Aを設けて、冷媒配管接続部7、7を配置してもよく、この場合も上記と同主旨の構造とすることにより、同様の効果が得られる。   As described above, as shown in FIG. 1 and the like, the refrigerant pipe connecting portions 7 and 7 are arranged in the notch 6A of the outer case 6 on the right rear portion of the indoor unit body, but the notch 6A of the outer case 6 is located on the left rear portion. In this case, the same effect can be obtained by adopting the same structure as described above.

また、冷媒配管接続部7、7の配置は、第2の外板6b寄りを下にして傾斜させたが、第2の外板6b寄りを上にして傾斜させてもよく、同様に冷媒配管接続部7、7に対して、室内機本体の右側面側及び下方が開放され、接続作業はやりやすくなる。但し、この場合は、配管固定具取付部11の底面傾斜させずに、全体的に冷媒配管接続部7、7との間隔は大きくする。   Further, the refrigerant pipe connection portions 7 and 7 are inclined with the second outer plate 6b close down, but may be inclined with the second outer plate 6b close up. The right side surface and the lower side of the indoor unit main body are opened with respect to the connection portions 7 and 7, and the connection work becomes easy. However, in this case, the interval between the refrigerant pipe connection portions 7 and 7 is increased as a whole without inclining the bottom surface of the pipe fixture attachment portion 11.

本室内機本体においては、2個の冷媒配管接続部7、7を、第1の外板6aの面上に投影した2個の冷媒配管接続部7、7の投影部が左右方向及び上下方向に間隔を有し、かつ、第2の外板6bに近い方の冷媒配管接続部7が遠い方の冷媒配管接続部7より下となるように傾斜して配置し、また、第1の外板6aの上部と第2の外板6bの上部から、冷媒配管接続部7、7の上方に延設する一体の配管固定具取付部11を設け、該配管固定具取付部11の底面を2個の冷媒配管接続部7、7の傾斜した配置に対応して傾斜させたので、開放側である室内機本体の下側及び側面側である第2の外板6bの対向側から冷媒配管接続部7、7への外部冷媒配管9、9の接続が容易にでき、また、配管固定具取付部11に取付けた配管固定具で冷媒配管接続部7、7に接続した外部冷媒配管9、9の固定作業が容易にできる。   In this indoor unit main body, the projection part of the two refrigerant pipe connection parts 7 and 7 which projected the two refrigerant pipe connection parts 7 and 7 on the surface of the 1st outer plate 6a is the left-right direction and the up-down direction. And the refrigerant pipe connection part 7 closer to the second outer plate 6b is inclined to be lower than the refrigerant pipe connection part 7 farther away, and the first outer An integrated pipe fixture attachment portion 11 extending above the refrigerant pipe connection portions 7 and 7 is provided from the upper portion of the plate 6a and the upper portion of the second outer plate 6b, and the bottom surface of the pipe fixture attachment portion 11 is 2 Since the refrigerant pipe connection portions 7 and 7 are inclined corresponding to the inclined arrangement, the refrigerant pipe connection is made from the opposite side of the second outer plate 6b on the lower side and the side of the indoor unit main body on the open side.
