The present invention relates to an air blowing device that is disposed in the vicinity of a ceiling of a building having a large space, such as a parking lot, a factory, a gym, a warehouse, or the like, and that carries air.

The air supply system installed in a building having a large space is generally installed in the vicinity of the ceiling of a building without an obstacle to transmit the wind to a distant place. In a large building, in the summer, in order to keep the hot air in the ceiling and to transfer the hot air in the horizontal direction, it is necessary to exhaust heat to the outside by the ventilation fan provided on the outer wall of the building. On the other hand, in the winter, in order to raise the warm air by the air conditioner or the like, the warm air near the ceiling is transmitted to the lower side, and it is necessary to circulate the heating in the building and improve the efficiency of the warm room. However, since the air blowing device is disposed at a high position, it is not easy to change the air blowing direction of the air blowing device in summer and winter.

It is known that a blower having a chamber, a blower, and a plurality of nozzles for blowing air from the blower at a different position from the chamber has air to be supplied from the blower to the different positions. Each nozzle side is switched to supply a baffle, and the nozzle is disposed in a large space air blowing device of the chamber so that the air blowing direction from the nozzle is substantially perpendicular to each other.

The above-described baffle is driven by a motor that is driven based on signals from elsewhere. Further, each of the nozzle systems is provided in an air outlet formed in a chamber, and at least one of the nozzles is capable of blowing an outlet center The line is freely rotatable about the center, and the air outlet of the freely rotatable nozzle is biased from the center line of the air outlet (for example, refer to Patent Document 1).

Further, in the chamber, a space for switching the baffle is necessary, and a large chamber (air blower frame) is necessary, and since the wind direction is changed in the chamber, there is a so-called large loss of air volume due to pressure loss. The problem.

The present invention has been made in view of the above-described drawbacks, and an object thereof is to provide an air blowing device that can easily and widely adjust the air blowing direction by a long distance, and that is small in size and small in air volume loss.

In order to achieve the object of solving the above problems, the present invention provides a blower device disposed near a ceiling of a building having a large space, including: a blower body having a blower fan therein, having an air intake port and an air blow port; The bracket is attached to the building, and supports the blower body in a pitching manner; an electric motor that tilts the blower body; and a remote controller that controls the motor.

The air blowing device of the present invention uses the air blowing direction by far The operation is easy, wide-ranging, and can be finely adjusted, small, and small in air volume loss. In addition, when the air blower body is tilted, the air intake port and the upper surface of the blower body are also tilted. Therefore, the air intake port and the upper surface of the blower body, which are easy to adhere to the dust, can be attached to the long handle in the downward or lateral direction.
