4, the lower side of the drawing corresponds to the rear side of the indoor unit 1, and the upper side of the drawing corresponds to the front side of the indoor unit. When the heat insulating material 11 is attached, the heat insulating material 11 is moved from the lower side to the upper side of FIG. The heat insulating material 11 can be easily inserted because the stopper 20 is elastically deformed in the direction of the white arrow at that time (see the black arrow in FIG. 4). It has become. Upon insertion of the heat insulating material 11 to a predetermined position, as shown in FIG. 4, since the stopper portion 20 presses the right upper portion 11B of the heat insulating material 11, it is possible to prevent removal of the heat insulating material 11. As shown in FIGS. 2 and 4, the stopper 20 is provided integrally with the exterior body (2C) at one end (the right end in FIG. 2) of the exterior body (2C) on the back side.
[0017]
2D shown in FIG. 2 is two holding parts provided at the lower part of the exterior body 2C, and holds the lower part 11C of the heat insulating material 11 as shown in FIG.
[0018]

Yes. For this reason, as shown in FIG. 2, the support portion 2 </ b> E prevents the horizontal, vertical and vertical deviations when the indoor unit is viewed from the back side. 11E is an opening.
[0019]
The support portion 2E shown in FIG. 6 is for supporting the shaft 12A of the auxiliary pipe presser 12. 2F is a guide for guiding the thick shaft 12B (pressing portion), and this guide penetrates the opening 11E of the heat insulating material. 2G is a support for preventing the auxiliary pipe presser 12 from shifting in the axial direction, and supports the central portion 12C of the thick shaft 12B.
[0020]
In the air conditioner configured as described above, a heat insulating material 11 is attached to the storage space 10 on the back side of the exterior body 2C. If this heat insulating material 11 is not attached, there is a risk of dew on the outer surface of the exterior body during cooling operation or dry operation, and the attachment of this heat insulating material is very important.
[0021]
The heat insulating material 11 is attached at a slight angle so that the lower end of the heat insulating material 11 is fitted between the presser portion 2D and the exterior body 2C. And the heat insulating material 11 is arrange | positioned in a predetermined position so that the support part 2E and the guide 2F may fit in each opening 11D and 11E. When the heat insulating material 11 is inserted, the stopper 20 at the right end is elastically deformed, so that a large force is not required, and the heat insulating material 11 is elastically deformed when placed at a predetermined position. The part returns to its original position, and the upper right portion 11B of the heat insulating material 11 is pressed as shown in FIG.
[0022]
Next, the auxiliary piping retainer 12 is attached to the support portion 2E. The longer shaft 12A (the right shaft in FIGS. 2 and 6) 12A of the pipe retainer 12 is inserted into the hole of the support portion 2E. After the thick shaft 12B is inserted until the portion of the thick shaft 12B hits the support portion 2E, the short shaft 12A on the opposite side is inserted into the hole 2E that supports this shaft. At that time, the support tool 2G hits and it becomes difficult to insert the shaft. Therefore, if the support tool 2G is lifted slightly so that the support tool 2G does not touch, the work becomes easy. When the auxiliary pipe presser 12 is attached, the heat insulating material 11 is pressed by the presser shaft 12B, and the heat insulating material 11 is held (see FIG. 1).
[0023]
Finally, the piping retainer 14 is attached. When the claw 17 is attached so as to be inserted into the opening 16 of the pipe retainer 14, the pipe retainer 14 is sandwiched and attached between the claw 17 and the support portion 17A as shown in FIG. At this time, the presser portion 15 of the pipe presser 14 is naturally positioned at the upper left portion of the heat insulating material 11, and the presser portion 15 presses the heat insulating material 11.
[0024]
Therefore, as shown in FIG. 2, the heat insulating material 11 is pressed by the stopper 20 at the upper right side of the heat insulating material when viewed from the rear side of the indoor unit, and is held by the two stoppers 2D at the lower side of the heat insulating material. The intermediate part on the upper side of the heat insulating material is pressed by the shaft 12B of the auxiliary pipe presser 12, and the upper left part is pressed by the presser part 15 of the pipe presser 14. Therefore, the heat insulating material 11 is attached to the exterior body 2C by pressing the heat insulating material 11 at a total of five locations.
[0025]
Thus, since the heat insulating material is not screwed, it does not require as much time as the time required for screwing, and the heat insulating material can be easily attached.
[0026]
Also, in air conditioners, the cross flow fan rotated during use and vibration at that time was one of the causes of loosening the screws, but since no screws were used to install the insulation, There is no slack. Also, since no screws are used, even when separating the exterior body and heat insulating material at the time of disposal, etc., the heat insulating material can be removed without a screwdriver, and no adhesive is used to install the heat insulating material. It is easy to remove the heat insulating material, and it is very easy to remove and separate the heat insulating material.
