Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling-mounted air conditioner, and more particularly, to a grill structure attached to an opening of a main body.

[0002]

2. Description of the Related Art Conventionally, a ceiling-embedded air conditioner has a fan 1 and a heat exchanger 3 surrounding the fan 1 in a box-shaped main body 1 opened downward, as shown in FIG. The open surface is covered by a shielding member 4 having an upper part provided with a dew receiving tray 4a in contact with the lower surface of the heat exchanger 3, and the fan 2
And a blowout port 6 is provided between itself and the main body, the suction port 5 is covered with a bell mouth 7, and a grill 80 facing the room is attached to the lower part of the main body 1. . As shown in FIG. 8, the grill 8 is provided with air outlets 8 a on four sides of the decorative panel 8, and heat insulating materials 9 a and 9 b are provided on both sides in the longitudinal direction of the air outlet 8 a and on the back surface of the decorative panel 8. The wind direction changing plates 10 are rotatably supported by the support shafts 10a at the air outlets 8a, respectively, and these adjacent wind direction changing plates 10 are driven by corner portions 8b of the decorative panel 8 by a driving device. 11 are connected to each other by a connecting member 12 which is linked to the protective cover 1 for protecting the connecting member 12 or the driving device 11 at the corner portion 8b.
3 or the protective cover 14 is attached.

However, the heat insulating materials 9a and 9b
Is configured to be adhered to the back surface of the decorative panel 8 by an adhesive or screwed to the back surface of the decorative panel 8 by a screw 15, so that workability is poor and disadvantageous in cost. Further, there is a problem that it is difficult to expect a secondary effect of reinforcing the strength of the decorative panel 8 by the heat insulating materials 9a and 9b. Therefore, pressing pieces 13b and 14b are provided on the protective covers 13 and 14 to press both sides of the heat insulating materials 9a and 9b, respectively, facing the decorative panel 8, and the pressing pieces 13b and 14b and the decorative panel 8 are provided. In this way, the heat insulating materials 9a and 9b are sandwiched between them to reinforce the strength of the decorative panel 8. However, this configuration has a problem that a gap is formed between the protective covers 13 and 14 and the heat insulating materials 9a and 9b due to steps or the like, and the confidentiality is impaired.

A wire (not shown) is hung down from the main body 1, and a hook (not shown) is provided on the decorative panel 8 of the grill 80, and the hook is hooked on the wire and temporarily fixed to connect the main body 1 to the grill 80. The maintenance can be performed without removing the electrical wiring (not shown). However, the thickness of the hook is limited by the thickness of the decorative panel 8, and there is a problem that the strength of the hook cannot withstand the weight of the grill 80. That is, if the thickness of the hook is increased in order to increase the strength of the hook, there has been a problem in that shrinkage occurs during molding and the appearance is impaired.

[0005]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems, improves the confidentiality of the heat insulating material to increase the heat insulating efficiency, and reduces the strength of the hook for hanging the grill without impairing the appearance.
