Abstract

PURPOSE:To facilitate the manufacture of a drain pan casing and a fan casing and contrive to lighten their weights and at the same time enable them to sufficiently withstand the loads of a heat exchanger and of a fan motor respectively by a structure wherein the drain pan casing and the fan casing are integrally molded with insulating structural material, the strength of which is nearly equal to that of sheet metal. CONSTITUTION:After both molds 17 and 18 are clamped together with each other with one rear side 15 of a metallic reinforcing part 9 being pinched therebetween, extremely reactive, special polyol and isocyanate are injected instantly under high pressure (about 80-200kg/cm<2>) through the bung hole 19 of the upper mold 18 so as to mix with each other by collision in the molds 17 and 18 in order to foam-mold at a low extent of foaming of 2-3 times. After that, the molds 17 and 18 are cooled and disassembled in order to take a drain pan casing 5 out of the molds 17 and 18. Further, a heat exchanger 7 is placed on the drain pan casing 5 fixed in an air conditioner 1 and yet fixed by a support fitting 16 and the weight of the heat exchanger 7 is received by the metallic reinforcing part 9 inserted in the drain pan casing 5.

(B) Prior art Generally, the drain casing that is built into large package-type air conditioners requires strength, so a drain hose connection tube is welded to the sheet metal container to remove oil, dirt, etc. After that, the container was painted, and then a heat insulating material such as styrofoam was attached to the outer wall of the container. As described above, since there are many manufacturing steps, the manufacturing process is labor-intensive and the manufacturing cost is high.Moreover, weight reduction could not be expected due to the adoption of a sheet metal container.

In addition, attempts have been made to form the fan casing incorporated into a small split-type air conditioner using high-density hard urethane foam with excellent heat insulation properties, but the outer wall of the fan casing is exposed as it is as the exterior body of the small air conditioner. If this happens, the external impact force will tear the surface membrane of the hard Frethane foam, reducing its insulation effect, so it was necessary to cover the outer wall of the fan casing with a strong protective cover such as hard resin or sheet metal.

(F) Effects of the Invention According to the present invention, a reinforcing metal fitting is partially inserted during RIM molding using polyurethane resin, which is lightweight and has excellent strength, heat insulation, and corrosion resistance. A heat insulating casing can be manufactured, and if this heat insulating casing is used as a vent casing or fan casing, the manufacturing process can be reduced and manufacturing costs can be reduced compared to conventional sheet metal vent casings that have undergone corrosion-resistant and heat-insulating treatment. In addition, there is no need to cover the fan casing with a protective cover as with conventional fan casings, which are made of hard urethane foam with high expansion ratio (in fact, it greatly contributes to the reinforcement structure of the air conditioner). I can do it.

Moreover, by using RIM molding, the connection part of the drain hose and the screw hole for mounting the fan can be integrally molded, and it is sufficient to provide sufficient strength by inserting reinforcing metal fittings only in the areas that receive the load of heavy objects. The fan casing can be used as a mounting stand for a heat exchanger and a mounting stand for a fan motor, improving work efficiency in assembling the air conditioner.
