(A) and FIG. 2 (B), FIG. 3, FIG. 4 (A) and FIG. 4 (B), FIG. 5 (A) and FIG. 5 (B), 1 is a wall-mounted air conditioner. The main body 2 is a suction port provided on the upper front surface and the upper surface of the main body 1, 3 is an outlet provided on the lower front surface, and 4 is a heat exchange provided in an air passage connecting the suction port 2 and the outlet 3. And 5, a blower fan provided in the air passage, 6 a left and right wind direction changing plate group rotatably supported by a support shaft 6a at a rear portion of the outlet 3, 7
Are two vertical wind direction change plates rotatably supported in front of the left and right wind direction change plate group 6.

By providing first separation preventing means, which will be described later, which is constituted by a number of convex portions and which prevents separation of the air flow, is provided on the rear side surface on the windward side of the left and right wind direction changing plate group 6. When the left and right wind direction changing plate group 6 is rotated, a very small turbulent flow a is generated as shown in FIG. 5A, so that the air flow A is separated even when the rotation angle is large. Since the phenomenon can be suppressed, and the entrainment of the outside air due to the relatively large turbulence a ′ as in the prior art can be suppressed, the dew condensation on the left and right wind direction changing plate group 6 is prevented. It has a configuration.

A first separation preventing means provided on the rear side surface which is on the windward side of the left and right wind direction changing plate group 6 to prevent separation of the air flow is provided on the windward side of the left and right wind direction changing plate group 6. By providing them on both sides of the rear part, the peeling phenomenon of the airflow A can be more effectively suppressed even when the left / right wind direction changing plate group 6 is turned to the left or right. In addition, as described above, since the entrainment of the outside air due to the relatively large turbulent flow a 'as in the prior art can be suppressed, the dew condensation on the left and right wind direction change plate group 6 is prevented. It has a configuration.

The rear side surface of the vertical wind direction changing plate 7 which is on the windward side is provided with a second separation preventing means which is constituted by a number of convex portions and which will be described later for preventing separation of the air flow. When the left and right wind direction changing plate group 7 is rotated, FIG.
As shown in (B), a very small turbulent flow b is generated, so that even when the rotation angle is large, the separation phenomenon of the air flow B can be suppressed. Since such a relatively large turbulence b ′ can suppress the entrainment of outside air, the configuration is such that dew condensation on the left and right wind direction changing plate group 7 does not occur.

A second separation preventing means, which is provided on the rear side surface on the windward side of the vertical wind direction changing plate 7 and prevents air flow from separating, includes a rear portion on the windward side of the vertical wind direction changing plate 7. By providing the air flow A on both sides, even if the vertical wind direction changing plate group 7 is turned to the substantially horizontal position or the almost vertical position, the separation phenomenon of the air flow A can be suppressed more effectively. And a relatively large turbulence b ′ as in the prior art, as described above.
Therefore, it is configured such that dew condensation on the vertical wind direction changing plate 7 does not occur.

Further, the first peeling preventing means and / or the second peeling preventing means have a large number of convex portions formed on the front surface, and the back surface is attached to the left and right wind direction changing plate group 6 and the vertical wind direction changing plate 7. And a structure in which the size and shape of the convex portion can be appropriately selected according to the size and performance of the main body 1 so as to be adhered. Become.

The first peel preventing means and / or the second peel preventing means is provided with a coarse grain surface 8 or 9 formed on the left and right wind direction changing plate group 6 and / or the vertical wind direction changing plate 7. By this, when the left and right wind direction changing plate group 6 and / or the vertical wind direction changing plate 7 are rotated, for example, the positions shown in FIG. 5A and FIG. The structure is such that the very small turbulences a and / or b occur.

Further, the first peel preventing means and / or the second peel preventing means are integrally formed on the left and right wind direction changing plate group 6 and / or the vertical wind direction changing plate 7, and are provided on the embossed surface 8 or 9. The ribs 8 'or 9' are slightly larger than the convex shape, so that, for example, when the horizontal wind direction changing plate group 6 and / or the vertical wind direction changing plate 7 are rotated, as shown in FIG. ) And FIG. 5B, the structure is such that the turbulent flows a and / or b are slightly larger than those of the above-described textured surface 8 or 9.

Further, the ribs 8 'or 9' can be used as shown in FIG.
As shown in FIG. 4 (B), by being continuously formed in a substantially C-shape that is alternately inclined, when the left / right wind direction changing plate group 6 and / or the vertical wind direction changing plate 7 are rotated, 5 (A) and 5 (B), the structure is such that the turbulent flows a and / or b are slightly larger than those of the ribs 8 'or 9' described above, These are appropriately selected so that the size of the turbulence a and / or b is set.

With the above configuration, FIG. 1, FIG. 2 (A) and FIG. 2 (B), FIG. 3, FIG. 4 (A) and FIG.
(B), and as shown in FIGS. 5 (A) and 5 (B), the rear side surface which is the windward side of the left / right wind direction changing plate group 6 and / or the windward side of the left / right wind direction changing plate group 6. The rear side surface is provided with a first separation preventing means and / or a second separation preventing means which is constituted by a number of convex portions and prevents separation of the airflow. Or when the vertical wind direction changing plate 7 is rotated, a very small turbulent flow a and / or b is generated, thereby suppressing the separation phenomenon of the air flow A even when the rotation angle is large. And the relatively large turbulence a ′ and / or b ′ as in the prior art can be suppressed from being entrained by outside air, so that the left and right wind direction change plate group 6 and / or the vertical wind direction change plate Avoid condensation on 7 Thus, a wall-mounted air conditioner that can effectively change the wind direction is obtained.
