[Industrial applications]

 The present invention relates to a diversion device in a bunker louver, which is mounted on the upper part of a wall of a building and discharges conditioned air in a desired direction in a room.

[0002]

[Prior Art]

 In the conventional bunker rubber, the spherical surface of the discharge cylinder is held by the frictional force on the inner surface of the ring-shaped holder, and the direction of the discharge cylinder is manually adjusted to release air conditioned in the desired direction. ..

However, since the bunker rubber is usually attached to the upper part of the wall, it is necessary to climb a high ladder or a stand when performing the adjustment work, which is not only a dangerous and troublesome operation, but also an indoor operation. When using, there is a disadvantage that it is difficult to work.

[0007]

[Action]

 According to the first means, the discharge cylinder rotates together with the horizontal axis about the rotation axis by the rotation of the first motor, and rotates around the horizontal axis by the rotation of the second motor. Therefore, the direction of the discharge cylinder is adjusted to a desired direction by the rotation angles of both motors.

According to the second means, the rotation of the first motor causes the rotational force to be transmitted to the side surface of the rack from the support plate and the guide portion that are integral with the rotation shaft, and the discharge cylinder that is integral with the rack is formed. It rotates with the rotation axis. Then, when the second motor is rotated, the second motor is rotated around the axis line orthogonal to the rotation axis along the inner surface of the holder, and the discharge port is adjusted in a desired direction.

The operating order of the first and second motors may be either first or simultaneous.
