Here, the color of the airflow guiding portion 500 and the color of each of the plurality of partition clips 600 are black, for example.

5(a)-(d) show the structures of the airflow guiding portion 500 and the partition wall clip 600. FIG. 5(a) and 5(b) are perspective views showing the structure of the airflow guiding portion 500. FIG. 5A and 5B, the angle of the airflow guiding portion 500 is different. The airflow guide portion 500 is a metal plate, and a plate-shaped planar portion 510 extending in the front-rear direction and the left-right direction is arranged at the substantially V-shaped tip portion of the airflow guide portion 500 . A guide opening 520 is provided in the planar portion 510 . At the left end and the right end of the planar portion 510, bent portions 512 are provided that widen upward in a substantially V shape. A plurality of slits 530 extending in the vertical direction are provided in the bent portion 512 . A portion of the partition clip 600 can pass through the airflow guide portion 500 .

FIG. 5(c) is a perspective view showing the structure of the partition clip 600. FIG. The base portion 630 of the partition clip 600 has a plate-like shape extending in the front-rear direction and the left-right direction. The length of the base portion 630 in the front-rear direction is shorter than the length of the airflow guide portion 500 in the front-rear direction. Two cover portions 610 having the same shape as the substantially V-shape of the airflow guide portion 500 are provided on the upper side of the base portion 630 . A wall portion 640 is also provided on the upper side of the base portion 630 to connect the two cover portions 610 and extend vertically and horizontally. A first guide receiving portion 620 is provided at the left end of the base portion 630, and a second guide receiving portion 622 is provided at the right end. A combination of the first guide receiving portion 620 and the second guide receiving portion 622 is a guide receiving portion extending in the front-rear direction.

As shown in FIG. 5D, the partition wall clip 600 is inserted from the upper side of the airflow guiding portion 500, and after the first guide receiving portion 620 and the second guide receiving portion 622 pass through the slit 530, the base portion 630 is The lower surface contacts the flat portion 510 . In this state, the partition clip 600 is attached to the airflow guide portion 500 and closes the slit 530 . The cover part 610 maintains the angle of the substantially V shape by urging the airflow guiding part 500 with a force directed from the inside of the substantially V shape to the outside.

The first blowout surface 120, the first plane portion 122, the second blowout surface 220, and the second plane portion 222 of FIG. 3 constitute a rail. The first guide receiving portion 620 and the second guide receiving portion 622 of each partition wall clip 600 slide from the front side to the rear side on such a rail, so that the first outer louver 100 and the second outer louver 200 are combined. An airflow guide portion 500 is assembled. At this time, the first flat portion 122 of the first outer louver 100 and the second flat portion 222 of the second outer louver 200 come into contact with the flat portion 510 of the airflow guiding portion 500 .

The airflow guiding portion 500 urges the first outer louver 100 and the second outer louver 200 from the inside of the air passage 310 toward the outside, and the opening lower end portion 134 of the first outer louver 100 and the second outer louver 200 . The distance of the open lower end 234 of 200 is kept constant. As a result, the airflow guiding part 500 forms the blowout opening 400 with the first outer louver 100 and the second outer louver 200 . Moreover, each of the plurality of partition wall clips 600 urges the air flow guide portion 500 from the inside of the substantially V-shaped shape toward the outside, and also separates the opening lower end portion 134 of the first outer louver 100 and the second outer louver 200 from each other. and the opening lower end 234 of the .

6(a)-(b) show the structure of the louver 1000. FIG. 6(a) is a perspective view of the louver 1000, and FIG. 6(b) is an enlarged perspective view of the louver 1000. FIG. These are shown similarly to FIGS. 1(a)-(b). A plurality of partition clips 600 are discretely arranged in the front-rear direction on the airflow guiding portion 500 . Also, each partition clip 600 is provided with a first guide receiving portion 620 and a second guide receiving portion 622, and the first guide receiving portion 620 and the second guide receiving portion 622 slide on a rail (not shown). Since the longitudinal length of the first guide receiving portion 620 and the second guide receiving portion 622 is shorter than the length of the partition wall clip 600 in the longitudinal direction, the rail and the first guide receiving portion 620 and the second guide receiving portion 622 are separated from each other. The rigor of dimensional control is relaxed, and workability of assembling the louver 1000 is improved.

FIG. 7 shows airflow paths in the louver 1000 . As previously mentioned, the airflow from the fan (not shown) travels from front to rear. The airflow guiding portion 500 directs the airflow from the upper side to the lower side, and the wall portion 640 guides the airflow to the guiding opening 520 . Also, the airflow is discharged to the outside through the guide opening 520 and the blowout opening 400 .

According to this embodiment, a plurality of partition clips 600 are attached to the airflow guiding portion 500, and the plurality of partition clips 600 are assembled to the first outer louver 100 and the second outer louver 200, so that the fitting portion can be divided. In addition, since the fitting portion is divided, the strictness of dimensional control can be relaxed. Moreover, since the fitting portion is divided, the assembling workability can be improved. Moreover, since the cover portion 610 of the partition clip 600 closes the slit 530 of the airflow guiding portion 500, airflow leakage can be suppressed. Further, since the cover portion 610 maintains the substantially V-shaped angle of the airflow guiding portion 500 , a stable airflow can be blown out from the air passage 310 of the hollow space 300 .

In addition, since the partition clip 600, the first outer louver 100, and the second outer louver 200 are in planar contact, the air flows between the airflow guiding portion 500, the first outer louver 100, and the second outer louver 200. It can be done easily. In addition, since it becomes difficult for air to pass between the airflow guiding portion 500 and the first outer louver 100 and the second outer louver 200, the generation of noise can be suppressed. In addition, since the airflow guide portion 500 has a configuration in which the guide opening 520 and the bent portion 512 are provided in the metal plate, the airflow guide portion 500 can be easily manufactured.
