Next, the operation of the illustrated air conditioner will be explained.

In this air conditioner, a blowout air flow W that is sucked in from an air suction port 2 and cooled or heated by a heat exchanger 6 to become cold or warm air is blown out from a front air outlet 3 and a bottom air outlet 4. This cools or heats the room.

The air volume is distributed to the front air outlet 3 and the lower air outlet 4 by a rotating shaft 15 driven by a swing motor 20 constituting a blade swinging mechanism 21.
Arrow A of the air volume distribution vane 11 with the swing center at 15
This is done by positioning after swinging in the direction.

Under normal conditions, as described above, the swinging position of the airflow distribution blade 11 is automatically performed by driving the swing motor 20, but if the swing motor 20 breaks down and the blade swinging mechanism 21 becomes inoperable. In this case, the links 18, 19 and the blade attachment 13 are operated by manually operating the rotary disk 23 which acts as a manual operation member, and the swinging position of the air volume distribution blade 11 is thereby determined. Therefore, it is possible to take emergency measures up to the time of repair.

Furthermore, in the air conditioner of this embodiment, when the fan 5 is operated with a small air volume, the following swing control of the air volume distribution blade 11 is performed.

That is, when the fan 5 is switched to a small air volume operation, the motor 26 is energized, the rotating body 25 is rotated by the drive of the motor 26, and the locking tool 30 is rotated by the rotation of the cam piece 29 accompanying the rotation of the rotating body 25. is forced to move upwards. The upward movement of the locking tool 30 causes the blade pieces 11a, 11a forming the air volume distribution blade 11 to swing upward (in the direction of arrow B in FIG. 2) about the support shafts 12, 12, 12, 12. It happens. The upward swinging of the blade pieces 11a, 11a as described above causes a decrease in the area of the passage leading to the front air outlet 3 and the lower air outlet 4, and this decrease in the area of the passage leads to a decrease in the area of the passage leading to the front air outlet 3 and the lower air outlet 4. This will encourage the speed of the airflow blown out from 3 and 4 to increase, greatly contributing to improving the indoor temperature distribution. When the fan 5 is switched to large air volume or medium air volume operation, the motor 26
The energization is stopped, and the return spring 34 returns to its original state by the urging force of the return spring 34.

It goes without saying that the present invention is not limited to the configuration of the above-described embodiments, and that the design can be changed as appropriate without departing from the gist of the invention.
