The present invention provides a ceiling panel that covers an opening surface of an embedded ceiling air conditioner, which is formed by injection molding using an ABS resin-based material. At the same time, the thick portion has a structure in which the inside is formed hollow and has a uniform thickness.

うになる等の特徴が得られる。Since the ABS resin material has heat resistance, oil resistance, impact resistance, and excellent workability, it is possible to use an ABS resin material to form an injection molded product having a uniform thickness, thereby producing a warp as a whole. Is reduced, dimensional accuracy is improved, and dents generated on the surface of the thick part are eliminated, and the appearance is improved, and the thick part can be hollowed, thereby securing rigidity and strength. In addition, in the case of an injection molded product such as an ABS resin, the strength can be secured by itself,
Since the surface finish such as coloring can be applied to itself, sheet metal inserts and vinyl chloride sheets for decoration, which were required for conventional molded products of foamed polyurethane resin, become unnecessary, and the weight and cost of ceiling panels are reduced. And so on.

For example, in the above embodiment, the ceiling panel is square, but the ceiling panel is not limited to this, and may be in accordance with the design. Also,
Although the description has been given of the ceiling panel having both the outlet and the inlet, the present invention can be applied to a ceiling panel having only one of them.

The ceiling panel body is made of an injection-molded product such as ABS resin, and the parts requiring strength are made thicker, and the thicker parts are hollowed out to make the wall thickness uniform. It is not necessary, and it is possible to secure the strength. In addition to the hollowness, the weight can be reduced, and the surface finish can be improved because injection molding can be applied. Since it is good and there is no need to stretch a decorative sheet, features such as cost reduction can be obtained.
