Air exchanged with the heat exchanger 3 is sent into the room through the air outlet 2.

  Behind the air outlet 2, a horizontal louver 10 (wind direction plate) and a vertical louver 4 that change the wind direction are provided. The lateral louver 10 is formed in a plate shape extending in the left-right direction, and is supported rotatably through a shaft (not shown) attached to the support member 5. The vertical wind direction of the air sent from the air outlet 2 is varied by the rotation of the lateral louver 10. Further, when the air conditioner 1 is not used, the air outlet 2 is closed by the lateral louver 10.

  The vertical louver 4 is configured by arranging a plurality of blades in the left-right direction. Each blade is supported by a fixing member 6 so as to be rotatable. The rotation of the vertical louver 4 changes the air direction of the air sent from the air outlet 2 in the left-right direction.

  FIG. 2 is an external perspective view of the lateral louver 10. The lateral louver 10 is formed in a plate shape by a front surface member 11 and a back surface member 12 (see FIG. 3). Cover members 14 having shafts 14 a are provided at both ends of the front surface member 11 and the back surface member 12 in the longitudinal direction.

  FIG. 3 shows an exploded perspective view of the lateral louver 10. The front surface member 11 and the back surface member 12 have the same cross-sectional shape in the longitudinal direction, and are formed by extrusion molding. Thereby, it can be formed at a lower cost than injection molding, and the same mold can be used for different models by changing the length in the longitudinal direction. For this reason, it is possible to improve the production efficiency and reduce the member cost accompanying it, and to save the mold cost. Further, the cover member 14 and the bearing member 13 described later can be made common to different models.

  The surface 11f of the surface member 11 is exposed to the outer surface side of the air conditioner 1 when the air outlet 2 (see FIG. 1) is closed. The back surface side of the surface member 11 is covered with the back surface member 12. 4 is a cross-sectional view of the front surface member 11 and the back surface member 12, the front surface member 11 is formed in a wave shape with a front surface 11f extending in the longitudinal direction. The back member 12 may also be corrugated. Further, the surface member 11 and the back member 12 may be knurled. An opening 11c is formed on the back side of the surface member 11, and a plurality of fitting grooves 11e extending in the longitudinal direction are formed in the opening 11c.

  A plurality of fitting protrusions 12c extending in the longitudinal direction are formed on the back surface member 12, and engaging claws 12a and 12b are formed at both ends in the width direction (left and right direction in the figure). When attaching the back surface member 12 to the front surface member 11, first, as shown in FIG. 5, one engagement claw 12a is engaged with the edge of the opening part 11c.

  Next, the fitting protrusion 12c is fitted into the fitting groove 11e to engage the engaging claw 12b with the edge of the opening 11c. Thereby, as shown in FIG. 6, the surface member 11 and the back surface member 12 are integrated.

Thereby, the cover member 14 can be easily prevented from being detached. In addition, since the notch part 17 (refer FIG. 3) serves as a guide at the time of attaching the cover member 14 while engaging the insertion part 14b, the cover member 14 can be attached easily. Further, if the outer shape of the cover member 14 and the outer surface of the surface member 11 are formed on the same surface, an unnecessary step does not occur in the visible range of the end portion of the lateral louver 10 and the aesthetic appearance may be impaired. Absent.

  According to the present embodiment, since the bearing member 13 is sandwiched between the front surface member 11 and the back surface member 12, ultrasonic bonding is not required, and the surface shape of the lateral louver 10 can be freely formed. Therefore, the degree of freedom in designing the lateral louver 10 is increased. Further, the horizontal louver 10 can be easily manufactured at a low cost. Moreover, since the back surface of the front surface member 11 is covered with the back surface member 12, the groove | channel extended in a longitudinal direction is not formed, but aesthetics can be improved.
