(Wind direction change grill body)
As shown in FIGS. 2 to 6, the wind direction changing grill main body 30 includes a substantially cylindrical frame portion 33 and a blade 31 fixed in the frame portion.

The frame portion 33 is composed of an even number of regular polygons that are equal to or greater than a quadrangle, and is an octagon in this example. Each side (33 ₁ , 33 ₂ , 33 ₃ , 33 ₄ , 33 ₅ , 33 ₆ , 33 ₇ , 33 ₈ ) of the frame portion 33 extends from the vertical wall 33a that supports the blade 31 and the base end of the vertical wall 33a. And a flange portion 33b projecting toward the outer peripheral side, and is formed in an L-shaped cross section. The blades 31 are arranged substantially parallel to each other in a plurality of stages at substantially equal intervals.

Thus, the wind direction can be changed in the four directions shown in FIGS. That is, as shown in FIG. 7, the first bracket 20A is disposed on the suction port 3a side (left side) of the outdoor unit 3, and the second bracket 20B is disposed on the opposite side (right side) from the suction port 3a. When the wind direction changing grill body 30 is attached to the pair of brackets 20A, 20B, the blade 31 is erroneously attached to the suction port 3a of the outdoor unit 3 with the direction of direction (wind direction changing direction) of the blade 31 being attached. This can be prevented (see FIGS. 11 to 14). That is, erroneous assembly can be prevented.

Incidentally, FIG. 11 toward the orientation of the edges 33 ₁ of the blade 31 upwardly, an example in which deflection of the air from the outdoor unit air outlet 3b upward, FIG. 12 is oriented direction of the sides 33 of the blade 31 ₁ the illustrates an example of deflection to the right obliquely upward air from the air outlet 3b toward the upper right direction, FIG. 13 from the outdoor unit air outlet 3b toward the orientation of the edges 33 ₁ of the blade 31 to the right an example for deflecting the air to the right, FIG. 14 is an example of deflecting the air from the outdoor unit air outlet 3b to the right obliquely downward toward the orientation of the edges 33 ₁ of the blade 31 to the lower right .

Here, discharge openings 41, 42 and 43 are formed in the vertical wall 33a of the two sides 33 ₂ and 33 ₈ in the orientation of the edges 33 ₁ of the blade 31 and adjacent its other side _{33 3,} 33 4, 33 _{5, 33} 6, 33 ₇ the outlet opening is not formed on. Therefore, the wind flowing along the directing direction of the blade 31 is smoothly blown from the wind direction changing grill body 30 as it is without being blocked by the vertical wall 33 a of the frame portion 33. Thereby, the fall of the ventilation resistance by having retrofitted the wind direction change grill 10 to the outdoor unit 3 can be prevented. Since the outlet opening in the vertical wall 33a of the sides 33 _4, 33 _5, 33 ₆ of the directivity direction opposite of the blade 31 is not formed, is intended to wind deflecting direction leaks air toward the opposite side It is possible to prevent a short circuit from occurring.
