ブに割れが発生することがあった。2. Description of the Related Art Conventionally, in a structure in which a resin molded product and a sheet metal molded product are separately formed and the ribs of the resin molded product are welded and combined into one, the resin and the sheet metal are welded with the ribs of the resin molded product. If the ribs of the resin molded product are welded together and combined with the sheet metal molded product because they do not adhere to each other, the clearance between the hole processed into the sheet metal molded product and the base of the rib of the resin molded product is actual Barely secured by alignment (0.2mm
By doing so, it was possible to prevent rattling of resin molded products and sheet metal molded products exclusively. However, in the front grille and the air guider present on the air blower circuit of the outdoor unit of the separation type air conditioner, the front grille which is a resin molded product and the air guider which is a sheet metal molded product are separately formed. If the ribs are welded and combined into one, expansion and shrinkage will occur due to heat in summer and winter, and shrinkage and expansion due to heat will occur in the front grille and the air guider of sheet metal molded products, respectively. Because the rates are different,
The clearance between the hole processed into the sheet metal molded product and the root of the rib of the resin molded product is barely secured by matching the actual product (0.2 mm
In order to prevent rattling by causing the resin ribs to crack, cracks may occur in the ribs of the resin molded product.

However, simply increasing the height or thickness of the ribs does not cause sink in resin processing. Since it was difficult to prevent the occurrence of cracks, as a method of preventing cracking, a method was used in which a resin section was placed at the root of the rib and the section was melted at the same time as the rib was welded, thereby increasing the volume of the rivet-shaped head after rib welding. .

(A) is an enlarged cross-sectional view of the joint, (c) is an enlarged view of the joint between the resin molded product and the sheet metal molded product after welding to the ribs by heating the resin molded product, and (d) is the coupling of (c). It is a part enlarged sectional view. When the resin molded product 1 and the sheet metal molded product 2 are separately formed and the ribs 3 of the resin molded product 1 are welded and combined into one,
The rib 3 was heated to finish the shape like the rivet-shaped head 4. However, when the resin molded product 1 and the sheet metal molded product 2 were not welded to each other, they did not adhere to each other.
The hole 6 and the clearance 6 at the root of the rib 3 of the resin molded product 1 are secured by the actual physical alignment or the like (a small margin of about 0.2 mm around the rib root). This prevents the molded product 2 from rattling. Next, a conventional example of preventing the rib 3 from cracking will be described with reference to FIG. FIG. 6 shows a process of preventing cracks in a joint portion when a resin molded product and a sheet metal molded product in the conventional example are separately combined and ribs of the resin molded product are welded and combined into one.
(A) is an enlarged view of a joining portion before welding in which a resin section is placed at the base of a rib, (b) is an enlarged sectional view of the joining portion of (a), and (c) is a welding process. FIG. 3D is an enlarged view of a joint between the resin molded product and the sheet metal molded product, and FIG. Conventionally, in order to prevent the ribs 3 from cracking, the strength of the ribs 3 has been improved by increasing the volume of the rivet-shaped head 4 after welding of the ribs 3. However, the height of the ribs 3 is simply increased or increased. It was difficult to increase the thickness because it was difficult to prevent sink marks generated on the back side of the ribs 3 of the resin molded product 1 during resin processing. A method of increasing the volume of the rivet-shaped head 4 after welding of the ribs 3 by simultaneously melting the resin pieces 7 when the placing ribs 3 are welded. However, work efficiency is poor and
There was a limit in improving the strength of the rib 3.
