[0002]

2. Description of the Related Art A conventional air conditioner is disclosed in JP-A-10-965.
As described in Japanese Patent Publication No. 7 (a), FIG.
The configuration shown in FIG. The housing 1, which is an indoor unit of an air conditioner, includes a blowout port 4 provided at a lower front portion of a front panel 3a, and a blowout passage 2 through which conditioned air flows forward and downward toward the blowout port 4. . Outlet 4
In order to change the direction in which the conditioned air blows up and down, a vertical wind direction plate 10 rotatably provided around a rotation axis C is provided.
0 is provided. The vertical wind direction plate 100 has a cross-sectional shape that is curved so as to follow the outer surface shape of the front panel 3a when the air conditioner is stopped.

[0005] As shown in FIG. 10 (a), the vertical wind direction plate 100 is moved from a stop position indicated by a two-dot chain line to one end 11.
By rotating the 0 side downward, the other end 120 moves to a substantially horizontal position facing the upstream side of the conditioned air, and the conditioned air is blown out in the front horizontal direction. In addition, as shown in FIG. 10B, by rotating the one end 110 side of the vertical wind direction plate 100 backward, the one end 110 moves to a substantially vertical position facing the upstream side of the conditioned air and moves downward. The conditioned air is blown out.

Further, as described in Japanese Patent Application Laid-Open No. 10-19300, the configuration is as shown in FIG.
The housing 1 of the air conditioner includes a blowout port 4 provided in front of and under the front panel 3a. At the outlet 4,
In order to change the upper and lower blowing directions of the conditioned air, two upper and lower wind direction plates 100a and 100b rotatably provided around the rotation axes C1 and C2, respectively, are provided. In the heating operation, when performing a direct blow, the first vertical wind direction plate 100a is placed in a substantially vertical position, and the second vertical wind direction plate 100b is positioned in front of the outlet 4 along the front surface of the front panel 3a. It is placed in a stop position to close the side, and conditioned air is blown downward.

[0005]

However, in the configuration of the first prior art (Japanese Patent Laid-Open No. 10-9657),
A sufficient horizontal and downward conditioned air flow cannot be formed. The lower arrow indicating the flow of the wind in FIG. 10A actually forms a strong flow of the downward component as shown by the broken line. Similarly, the upper arrow indicating the flow of the wind in FIG. 10B actually forms a strong horizontal component flow as shown by the broken line.

In the configuration of the second prior art (Japanese Patent Laid-Open No. 10-9657), the downward flow tends to be somewhat improved as compared with the first conventional example. However, FIG.
In fact, the upper arrow indicating the flow of the wind cannot be said to form a sufficient downward flow as indicated by the broken line. The formation of the horizontal flow has the same problem as the first conventional example.
