Then, as shown in fig. 6(B), the sheet metal SH is rotated by 180 degrees about the point O together with the table, and the first punch is moved in the direction perpendicular to the sheet surface, so that a second group H2 is punched in the other half portion SH2 of the sheet metal SH, which extends intermittently in the circumferential direction with the point O in the drawing as the center and is provided with a plurality of turns in the radial direction with the point O in the drawing as the center.

Next, as shown in fig. 6C, a second punch (not shown) is moved in a direction perpendicular to the sheet surface, so that a third group of holes H3 is punched in the other half portion SH2 of the sheet metal SH, the third group of holes H3 being intermittently extended in the circumferential direction with the point O in the drawing as the center and being shifted from the second group of holes H2 (the multiple circles of holes included in the third group of holes H3 are on the same circle as the multiple circles of holes included in the second group of holes H2, respectively).

Then, as shown in fig. 6(D), the sheet metal SH is rotated 180 degrees around the point O together with the table, and the second punch is moved in the direction perpendicular to the paper surface, so that a fourth group of holes H4 is punched in the half portion SH1 of the sheet metal SH, which extends intermittently in the circumferential direction around the point O in the drawing and is shifted from the first group of holes SH1 (the multiple holes included in the fourth group of holes H4 are on the same circle as the multiple holes included in the first group of holes H1, respectively).

Next, as shown in fig. 6(E) and 6(F), a press operation similar to the press operation shown in fig. 6(a) and 6(B) is continued by a third punch (not shown), and a plurality of groups of holes are continuously formed between two radially adjacent circles of holes included in the first group of holes H1, the second group of holes H2, the third group of holes H3, and the fourth group of holes H4, and openings are formed on one pair of opposite sides of the sheet metal SH.

Then, as shown in fig. 6(G) and 6(H), a press operation similar to the press operation shown in fig. 6(C) and 6(D) is continued by a fourth punch or the like, not shown, and a plurality of sets of holes are continuously formed between two radially adjacent circles of holes included in the first set of holes H1, the second set of holes H2, the third set of holes H3, and the fourth set of holes H4, whereby the first grid 312 and the second grid 313 are formed on the sheet metal SH, and openings are continuously formed on a pair of opposite sides of the sheet metal SH.

Next, as shown in fig. 6(I) and 6(J), the central portion 311 is formed in the sheet metal SH by a punch or the like, not shown, and the other set of edges of the sheet metal SH is punched out, thereby completing the press working.

After the stamping process is completed, the part corresponding to the grid main body can be leveled, so that slight deformation caused by stamping can be improved.

Then, as shown in fig. 6(K) and 6(L), the sheet metal SH is bent at its periphery to form the side plate 32 (including the hook 321), the flange 33, and the like.

Finally, spraying processing is performed on the sheet metal SH, so that the air outlet grille 31 is manufactured.

(main effect of the present embodiment)

According to the present embodiment, since the first and second louvers 312 and 313 of the grill main body 31 of the outlet grill 30 are coplanar, the strength of the outlet grill 30 is easily increased as compared with the case where the first and second louvers are not coplanar; in addition, in the manufacturing process, the grid main body 31 is easy to support and position, and the manufacturing process is easy to simplify; further, since the grill main body 31 of the outlet grill 30 is made of metal, it has a high aging resistance and does not cause a problem of burning due to an open flame, as compared with a case where the grill main body is made of resin, and therefore, it is highly safe.

In addition, according to the present embodiment, since the outlet grille 30 is a metal member formed integrally, there is no risk of disconnection of the welding points due to cold welding, and the strength of the outlet grille 30 can be improved, as compared with an outlet grille formed by connecting a plurality of wires by welding using metal rods; moreover, the welding points are not impacted due to the large air quantity passing through the air outlet grille 30 and/or the vibration in long-term use, so that the welding points are loosened, and the strength of the air outlet grille 30 is weakened; moreover, the strength of the air outlet grid 30 is not weakened due to rusting of welding points caused by contact with rainwater and the like in use; moreover, welding treatment is not needed to be carried out on each connecting point, and the manufacturing process is simplified.

Further, according to the present embodiment, when the grill 30 is manufactured, since the sheet metal SH for manufacturing the outlet grill 30 is placed on the table so that the back surface (i.e., the surface facing the fan assembly 20 when assembled to the casing 10 of the outdoor unit 1) faces the outside of the paper surface and is pressed, that is, from the side corresponding to the back surface of the grill main body 31, a certain curvature can be formed at the edges of the first grill 312 and the second grill 313, which contributes to smooth flow of the outlet air flow, noise reduction, and air volume increase.

Further, according to the present embodiment, when the grid 30 is manufactured, since the third group of holes and the second group of holes are punched with a gap therebetween and the fourth group of holes and the first group of holes are punched with a gap therebetween, it is possible to prevent the sheet metal SH from being deformed, to ensure sufficient strength and flatness of the manufactured outlet grid, and to easily ensure that the width of the finally formed grid is as small as possible, and to ensure the air volume, as compared with the case where the adjacent holes are simultaneously punched.
