A left-right airflow direction changing plate 54b formed in a rectangular tube having front and rear openings that deflect the generated air in the left-right direction is provided. Further, as shown in FIG. 9 (B), a centrifugal fan 55 for sending out the heat-exchanged air to the left / right airflow direction changing plate 54b is arranged in the back of the suction port 53. The centrifugal fan 55 is configured to rotate clockwise when viewed from the front. As shown by the arrow in FIG. 9B, air is sucked in from the front of the centrifugal fan 55 and blown mainly from the upper part to the right, The fan casing 56 guides air from the rear to the front of the left / right airflow direction changing plate 54b. Also, the left and right wind direction changing plate 54b
Has a shaft on the upper and lower surfaces thereof, is pivotally supported by supporting shafts provided on the upper and lower sides of the outlet 54, and automatically rotates to the left and right by a drive mechanism (not shown).

8 and 8 are provided respectively.

As shown in FIG. 3, the left / right airflow direction changing plate 10 is connected to a rectangular vertical plate portion 10c having an upper part directed from the front to the rear and a lower part of the vertical plate part 10c, and the front and the rear are opened. The tubular portion 10d having a triangular cross section is integrally formed. The rear of the vertical plate portion 10c and the triangular tubular portion 10d is the air inflow side 10b, and the front is the outflow side 10a. A shaft 10e is provided so as to project from the upper portion of the vertical plate portion 10c and the bottom surface of the triangular tubular portion 10d, and the shaft 10e is pivotally supported by the support shaft portions provided above and below the air outlet 8 to rotate right and left. It has a structure that can be freely attached.

Next, the operation of the above-mentioned integrated air conditioner will be described. As shown in FIGS. 2 and 4, the indoor air sucked from the suction port 7 of the front panel 6 is cooled by the indoor heat exchanger 11 to condense the moisture contained on the surface thereof, and through the seal plate 13. Fan casing 15
The air flows into the inside and is blown out toward the front from the blowout passage 15b by the centrifugal fan 14. The blown air flows into the left / right airflow direction changing plate 10 from the inflow side 10b as shown in FIG. The air passing through the upper part of the inflow side 10b has a large air volume due to the characteristics of the centrifugal fan as described in the conventional example. Therefore, by configuring one wind direction plate, which is configured by the left and right two sheets in the conventional example, Wind resistance can be reduced to deliver wind further. In addition, the lower triangular tubular portion 10
In the portion of d, the left and right wind direction plates 10d1 forming the hypotenuse of the triangle are arranged so as to be inclined, so that the centrifugal fan 1
Since the wind can be deflected in accordance with the amount of air sent from No. 4 (the upper part of the blowout port is large and the lower part is the lower part), the resistance to the wind can be reduced and the air can be efficiently blown. The air above the outlet 8 can be blown far away, and the air below the blower outlet 8 can be blown nearby to cool the room evenly.

Next, another embodiment will be described. Figure 5
Is a second embodiment, and this left and right airflow direction changing plate 20 has a continuous portion 20d1 of a triangular tubular portion 20d and a vertical plate portion 20c from the front to the rear as compared with the example of the left and right airflow direction changing plate 10 of FIG. The structure is inclined downward as it goes to. With this structure, the air above the air outlet 8 can be deflected upward and can be blown farther than in the example of the left / right airflow direction changing plate 10 in FIG. 3.

FIG. 6 shows a third embodiment. This left / right airflow direction changing plate 21 is directed from the front to the rear of the bottom surface of the triangular tubular portion 21d as compared with the example of the left / right airflow direction changing plate 20 in FIG. The width is narrowed accordingly. With this structure, the air below the air outlet 8 can be diffused to the left and right to be blown, so that the air can be blown in a wider range compared to the example of the left-right airflow direction changing plate 20 in FIG.

FIG. 7 shows a fourth embodiment. This left / right airflow direction changing plate 22 has a vertical plate portion 22c having a triangular tubular portion 22d and a vertical plate 22d as compared with the example of the left / right airflow direction changing plate 21 of FIG. The structure is such that the width increases from the rear of the continuous portion 22d1 with the portion 22c toward the upper side. With this structure, the wind above the air outlet 8 can be deflected in a larger amount as compared with the example of the left / right airflow direction changing plate 21 in FIG. 6, and when the left / right airflow direction changing plate 22 is rotated, a wide range, and Can blow far away.

FIG. 8 shows a fifth embodiment. The left and right wind direction changing plate 23 has a structure in which the left and right wind direction changing plates 23d1 are curved outward as compared with the example of the left and right wind direction changing plate 22 shown in FIG. Has become. With this structure, the air resistance when the air below the air outlet 8 is diffused to the left and right to be blown is reduced.
As compared with the example of the left / right airflow direction changing plate 22, the air can be efficiently sent.

[0020]

As described above, according to the present invention,
By forming the right-and-left airflow direction changing plate with a rectangular vertical plate portion whose upper part extends from the front to the rear and a cylindrical part with a triangular cross-section open to the front and the rear, which is connected to the lower part of the vertical plate part. Since the air having a high flow rate to be blown away from the upper part of the air outlet can be blown out from the lower part and the air can be blown out to the left and right in a wide range, it is possible to uniformly cool the room.
