  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

(Embodiment 1)
As shown in FIGS. 1 and 2, the ceiling-embedded air conditioner according to Embodiment 1 of the present invention includes an adapter mounting plate 3 in which an adapter 2 that is connected to the ventilation duct 1 is provided on a plate-shaped mounting plate 3a. And the adapter mounting plate 3 is vertically attached to the main body mounting frame 6 attached to the ceiling opening 5 formed on the ceiling surface 4 and then inserted through the opening of the main body mounting frame 6 to form the exhaust formed on the plurality of sides. The air conditioner main body 8 is installed on the ceiling surface 4 with the air vent 7 serving as a mouth and an air inlet connected to the adapter 2.

  In order to prevent the adapter 2 and the air vent 7 of the air conditioner main body 8 from being in an airtight state so that there is no air leak, a packing 9 for preventing air leakage is provided on the surface of the mounting plate 3a facing the outer periphery of the air vent 7. Is affixed.

  Further, in the vicinity of the lower portion of the mounting plate 3a where the packing 9 is affixed, a packing protecting portion 10 made of a hard elastic material that is the same type of elastic material as the packing 9 and has a smaller compression amount than the packing 9 is applied. ing. The packing protection part 10 is slightly larger than the packing 9 in the left-right direction and has a slightly lower height (natural state) in the compression direction.

  The packing protection unit 10 is subjected to a surface treatment that reduces frictional resistance. As this surface treatment, a high-temperature plate or the like is applied to the surface of the packing protection part 10 for a very short time to increase the surface density and smooth the surface, or the surface of the packing protection part 10 is coated. In order to make it smooth, there is a means for immersing the surface portion of the packing protection portion 10 in the coating liquid, but it is not limited to this as long as it reduces the frictional resistance of the surface.

  Moreover, as shown in FIG. 3, the surface to which the packing 9 of the mounting plate 3a is attached is inclined in a direction closer to the side surface of the air conditioner body 8 as it goes upward.

Moves toward the packing 9 along the surface of the mounting plate 3a. However, since the packing protection part 10 is provided below the packing 9 before reaching the packing 9, the side surface upper end part 8a is in sliding contact with the packing protection part 10 while being slightly elastically deformed and compressed. As a result of the surface treatment of the packing protection part 10, the frictional resistance during sliding contact is reduced, and the side surface upper end part 8a passes through the packing protection part 10 smoothly.

  Thus, since the packing protection part 10 is provided in the vicinity of the packing 9, the side surface upper end part 8a of the air conditioner main body 8 is not caught by the lower end of the sticking part of the packing 9, and the packing 9 may be peeled off or torn off. In addition, the frictional resistance when passing through the packing 9 is also reduced.

  Further, since the packing protection part 10 is made of an elastic material harder than the packing 9, even if the air conditioner body 8 is inserted so that the packing protection part 10 receives an impact, the impact protection is absorbed and the upper part moves smoothly. Can be made.

  When the air conditioner body 8 is pushed upward, the packing sticking surface of the mounting plate 3a that contacts the side surface is inclined upward to the side surface side of the air conditioner body 8. Will grow. Further, as shown in FIG. 5, when the air conditioner main body 8 is pushed up to a position where the lower end of the air conditioner main body 8 comes into contact with the ceiling surface 4, the air conditioner main body is attached to the engaging portion 11 provided on the mounting plate 3a and facing obliquely downward. The side surface upper end portions 8a are engaged so as to be pulled together, and the packing 9 is finally compressed by a predetermined amount to ensure airtightness.

  As described above, even if the compression of the packing is restricted to a predetermined amount by providing the packing protection part 10, the airtightness by the packing 9 after installation can be reliably obtained.

  In the first embodiment, the configuration in which the packing protection part 10 is provided on the adapter mounting plate 3 is shown. However, as shown in FIG. 6, the packing is provided on the outer peripheral part of the air vent 7 of the air conditioner body 8. Even if 9 is pasted and the packing protection part 10 is pasted in the vicinity of the upper part of the packing 9 of the air conditioner main body 8, the same effect can be obtained.
