2 and the upper piece.

As described above, the mounting frame 61 and the blade 6
2 are made of sheet metal, and both of them have almost no elastic force.
The work of mounting the hologram on the hood is performed in the following procedure.

First, as shown in FIGS. 4 and 5, a cushion member 70 is attached to the support piece 68 on the upper side of the blade 62, and the blade 62 closes the air outlet 3 of the attachment frame 61. The blade 62 is inclined with respect to the air outlet 3, and the lower supporting piece 68 and the projection 69 are provided.
Into the support holes 66 and the mounting holes 67 in the lower piece of the mounting frame 61, respectively.

Then, the blade 62 in the oblique state is raised in a substantially vertical state as shown in FIG. 5, and then the blade 62 is moved upward in the mounting frame 61, so that the blade 62
Is inserted into the support hole 65 of the mounting frame 61. Here, since the dimension H between the end of the support piece 68 of the blade 62 and the lower side of the blade 62 substantially coincides with the inner dimension I of the mounting frame 61, the blade 62 in an oblique state is placed inside the mounting frame 61. Can be raised almost vertically.

After the support piece 68 on the upper side of the blade 62 is inserted into the support hole 65 of the mounting frame 61, the blade 62 is rotated about the support piece 68, and the projection 69 of the blade 62 The blade 62 is restricted in the vertical direction by hitting the inner surface 71 of the lower piece. In other words, the end of the blade opposite to one end of the support piece 68 of the blade 62 has a mounting hole 65 when the blade 62 is mounted.
At the time of rotation of the blade 62,
A projection 69 is provided which is applied to (the inner surface of the lower piece of the mounting frame 61).

The blade 62 is mounted in this manner, and a plurality of blades 62 are fitted into the mounting frame 61. At this time, the cushion member 70 is slightly compressed between the blade 62 and the upper piece 63 of the mounting frame 61, so that the elastic force of the cushion member 70 maintains the rotating state of the blade 62.

The wind directions of the blades 62 are individually controlled, and the wind directions of the blades 62 are not linked. This is this air conditioner 1
The air outlet 3 is disposed under the floor so as to be connected to the underfloor space 19, so that the blade 62 is operated only when the air conditioner 1 is installed. As described above, since the number of times of operating the blade of this air conditioner is extremely small (only once) as compared with the number of times of operating the blade of a general home air conditioner, a structure called an "auto louver mechanism" is necessary. do not do. Moreover, the mounting frame 61 and the blade 62
Is formed of a flat sheet metal plate to reduce the cost of the wind direction changing device.

[0021]

As described above, according to the present invention, the dimensions of one end of the support piece and the end face of the blade opposite to the one end substantially match the inner dimensions of the mounting frame. At the same time, mounting holes are provided in these opposed pieces, and the end face of the blade opposite to one end of the supporting piece of the blade is inserted into the mounting hole when the blade is mounted, and when the blade rotates, the blade is inserted into the mounting hole. Since a projection is provided for the opposing piece,
The support pieces and protrusions provided on the blade are of a flat plate shape similar to the blade, and the cost can be reduced sufficiently. Further, by making the support holes of the mounting frame into which these support pieces are inserted into a substantially circular shape, the blade can be smoothly rotated even when the support pieces are flat.
