[Problems to be solved by the invention]
However, in recent years, there is a tendency to make the decorative panel thin in order to make the appearance clear from the viewpoint of design. However, in the above configuration, the wind insulating heat insulating material is provided on the decorative panel side by the thickness of the wind insulating heat insulating material. There is a problem that it is difficult to secure the space when the decorative panel is thinned.
In the present invention, in view of the above-described problems, it is possible to attach a wind insulation heat insulating material that shields some of the air outlets provided on the four sides of the decorative panel without depending on the thickness of the decorative panel. An object is to provide a ceiling-embedded air conditioner.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the embodiments of the present invention shown in FIGS.
First, a first embodiment of the present invention shown in FIGS. 1 to 3 will be described.
As shown in FIGS. 1 and 2, reference numeral 5 denotes a ceiling-embedded air conditioner main body suspended on an attic wall surface 2 above the ceiling 1 by suspension bolts 3 and suspension nuts 4 embedded in the attic wall surface 2. A suction bell mouth 7 is opened at the center of the lower surface 6 of the main body 5, and four openings 9 of the outlet passages 8 are provided around the suction bell mouth 7 in different directions. Reference numeral 10 denotes a decorative panel mounted on the lower surface 6 of the main body 5 so as to contact the lower surface of the ceiling 1. The decorative panel 10 corresponds to the suction grille 11 at the center and the four openings 9 on the four outer peripheral sides. The four air outlets 12 provided with the wind direction board 13 are provided.
A filter 14 is provided on the upper surface of the suction grill 11, a blower fan 15 driven by a motor 16 is provided above, and a heat exchanger 17 is provided on the outer periphery of the blower fan 15.
In the blower fan 15, room air is filtered and sucked from the suction grill 11 by the filter 14, and the heat exchanged by the heat exchanger 17 is blown out from the outlet 12.
As shown in FIG. 2 and FIG. 3, a wind insulation heat insulating material 18 formed of a foam material such as black foamed polyethylene is provided at the air outlet 12 that is desired to stop the air blowing due to installation conditions among the four air outlets 12. Installing. The wind-insulating heat insulating material 18 includes a fitting portion 19 that fits into the blowing passage 8 and a flange portion 20 that is sandwiched between the lower surface 6 of the main body 5 and the decorative panel 10. A sealing material 21 formed of foamed polyurethane foam or the like is affixed to the entire circumference of the back surface of the decorative panel 10 with which the flange portion 20 abuts with a double-sided adhesive or the like so that the blown air and the sucked air do not leak. Yes.
By making the thickness t1 of the flange portion 20 sufficiently smaller than the thickness t2 of the sealing material 21, the restoring force of the sealing material 21 can be obtained even at the four corners on the back surface of the decorative panel 10 without the flange portion 20. By this, since it is in close contact with the lower surface 6 of the main body 5, it is possible to reliably prevent leakage of blown air and intake air.
In addition, by using a black material for the wind shield heat insulating material 18, the wind shield heat insulating material 18 is not conspicuous when the air outlet 12 is viewed, and the appearance is not impaired.
[0013]
Next, a second embodiment of the present invention shown in FIG. 4 will be described.
The configuration of the wind-shielding heat insulating material and the configuration of the portion sandwiching the wind-shielding heat insulating material are different from the first embodiment.
The wind-shielding heat insulating material 18 cuts the insertion part 19 and the flange part 20 into sheet-like foam materials such as foamed polystyrene, respectively, and cuts the insertion part 19 and the flange part 20 into a double-sided adhesive or the like. Since the wind-insulating and heat-insulating material 18 can be produced with a low-cost initial investment such as a big type, it can be made inexpensive in terms of cost.
In addition, when a black material cannot be obtained with a polystyrene foam or the like for the sheet-like foam material forming the flange portion 20, black is sprayed on only one surface of the sheet-like foam material, or a black film is laminated. Thereby, the lower surface side facing the said blower outlet 12 can be made black.
Further, by forming a fitting recess 22 into which the flange portion 20 is fitted on the lower surface 6 of the main body 5, even if the flange portion 20 is thick to some extent, the airtightness of the sealing material 21 is inhibited. There can be no configuration.
[0014]
Next, a third embodiment of the present invention shown in FIGS. 5 and 6 will be described.
The structure of the wind-shielding heat insulating material is different from the first embodiment.
Even if the decorative panel 10 becomes thinner or the wind direction plate 13 becomes larger by forming the recess 23 on the lower surface of the wind shielding heat insulating material 18 so as not to interfere when the wind direction plate 13 tilts, It can be set as the structure which the wind-shielding heat insulating material 18 and the said wind direction board 13 do not interfere.
[0015]
【The invention's effect】
As described above, according to the present invention, it is possible to attach the wind-shielding heat insulating material that shields some of the air outlets provided on the four sides of the decorative panel without depending on the thickness of the decorative panel. It becomes a ceiling-embedded air conditioner.
