DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an in-ceiling type air conditioner, and more particularly, to a structure of a wind insulating material to be mounted on an outlet.

[0002]

2. Description of the Related Art As shown in FIG. 7, a conventional ceiling-mounted air conditioner includes a plate-shaped wind-insulating heat insulating material 18 for shielding some of outlets provided on four sides of a decorative panel. The fitting panel 30 is fitted into a fitting recess 30 having a depth corresponding to the thickness of the wind insulating material 18 formed around the entrance of the air outlet 12 on the rear surface of the decorative panel 10, and the decorative panel 10 is embedded in the ceiling. By being attached to the lower surface of the air conditioner body 5,
Was attached.

[0003]

However, in recent years, there has been a tendency to make the decorative panel thinner in order to make the appearance clearer from the viewpoint of design.
Due to the thickness of the wind insulation material, the wind insulation material needs to enter the decorative panel side, and when the decorative panel is made thin, it is difficult to secure the space. Was. In the present invention, in view of the above-mentioned problems, it is possible to attach a wind-insulating 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 of the present invention is to provide a ceiling-mounted air conditioner.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a ceiling-embedded air conditioner main body suspended above a ceiling and a makeup mounted on the lower surface of the main body so as to abut the lower surface of the ceiling. Panels, by attaching wind-insulating insulation to some of the outlets provided with wind direction plates provided on four sides of the decorative panel so as to be sandwiched between the lower surface of the main body and the decorative panel, In the ceiling-embedded air conditioner in which the number of the outlets is limited, a fitting portion for fitting the wind-insulating heat insulating material into an outlet passage opened on the lower surface of the main body, the lower surface of the main body, and the decorative panel And a sealing member that abuts on and seals the flange portion around the entire back surface of the decorative panel.

[0005] The thickness of the flange portion of the wind-insulating heat insulating material is sufficiently smaller than the thickness of the sealing material.

[0006] Further, a fitting concave portion is formed in the lower surface of the main body to be fitted with a flange portion of the wind shielding heat insulating material.

[0007] Further, a recess is formed on the lower surface of the wind shield and heat insulating material so that the wind direction plate does not contact the lower surface.

Further, the fitting portion and the flange portion of the wind-insulating heat insulating material are individually cut out of a sheet-like foam material into a plate shape, and both are vertically attached.

[0009] Further, a styrofoam is used as the sheet-like foam material.

[0010] Further, the lower surface of the wind insulating material is colored with a black color.

Further, a material colored in a black system such as foamed polyethylene is used for the wind-shielding heat insulating material.

DESCRIPTION OF THE PREFERRED EMBODIMENTS 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 a roof attic wall 2 above the ceiling 1 by suspension bolts 3 and suspension nuts 4 embedded in the roof attic wall 2, A suction bell mouth 7 is opened in the center of the lower surface 6 of the main body 5, and openings 9 of four outlet passages 8 facing different directions are provided around the suction bell mouth 7. 10 is the main body 5 so as to contact the lower surface of the ceiling 1.
A decorative panel attached to the lower surface 6 of the panel. The decorative panel 10 has a suction grill 11 in the center, four outer peripheral portions on four sides corresponding to the four openings 9, and four air outlets 12 provided with wind direction plates 13.
Is provided. A filter 14 is provided on the upper surface of the suction grill 11, and a blower fan 15 driven by a motor 16 is provided further above. A heat exchanger 17 is provided on the outer periphery of the blower fan 15. The blower fan 15 filters the indoor air from the suction grill 11 with the filter 14 and sucks the air, and blows out the air heat exchanged by the heat exchanger 17 from the outlet 12. FIG.
As shown in FIG. 3 and FIG. 3, a wind-insulating heat insulating material 18 made of a foam material such as black foamed polyethylene is attached to one of the four outlets 12 where the blowing is desired to be stopped depending on installation conditions and the like. . The wind-insulating heat insulating material 18 is provided in the outlet passage 8.
And a flange portion 20 sandwiched between the lower surface 6 of the main body 5 and the decorative panel 10. A sealing material 21 made of a foamed polyurethane foam or the like is attached by a double-sided adhesive or the like so that the blow-out air and the suction air do not leak around the entire back surface of the decorative panel 10 with which the flange portion 20 contacts. I have. By making the thickness t1 of the flange portion 20 sufficiently smaller than the thickness t2 of the sealing material 21, the thickness t1 of the flange portion 2 is reduced.
Even at the four corners on the back surface of the decorative panel 10 where there is no zero, the restoring force of the sealing material 21 ensures the close contact with the lower surface 6 of the main body 5, so that the leakage of the blown air and the sucked air is reliably prevented. Can be. Further, by using a black material for the wind-insulating heat insulating material 18, the air outlet 1
2, the wind-shielding heat insulating material 18 does not stand out and does not impair the appearance.

Next, a second embodiment of the present invention shown in FIG. 4 will be described. The second embodiment is different from the first embodiment in the configuration of the wind-insulating heat insulating material and the structure of the portion sandwiching the wind-insulating heat insulating material. The wind insulating material 18 includes a fitting portion 19 and a flange portion 20.
By cutting a sheet-shaped foam material such as styrene foam into a plate of a required size, and bonding the cut-out fitting portion 19 and the flange portion 20 vertically with a double-sided adhesive or the like to form the windshield. Since the heat insulating material 18 can be manufactured with a cheap initial investment such as a big type,
It can be inexpensive. If the sheet-like foam material forming the flange portion 20 is not available as a black material such as Styrofoam, only one surface of the sheet-like foam material is sprayed with black, or a black film is laminated. Thereby, the lower surface side facing the outlet 12 can be made black. Further, by forming a fitting concave portion 22 in 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 not hindered. There can be no configuration.

Next, a third embodiment of the present invention shown in FIGS. 5 and 6 will be described. The configuration of the wind insulating material is different from that of the first embodiment. By forming the concave portion 23 on the lower surface of the wind shield heat insulating material 18 so as not to interfere when the wind direction plate 13 is tilted, even if the decorative panel 10 becomes thinner or the wind direction plate 13 becomes larger, It is possible to adopt a configuration in which the wind insulating material 18 does not interfere with the wind direction plate 13.
