  In the conventional system described above, the branch duct and the air volume and wind direction adjusting means are provided, so that the structure is complicated, heavy and expensive.

  The present invention aims to solve such problems.

  In order to solve the above-described problem, in the present invention, a blow-out cylinder is protruded and attached inward from an opening formed in a plate body constituting one surface of the air flow path. An air outlet device in which an inclined opening is formed in the inner corresponding portion is proposed.

  In the present invention, in the above configuration, the blowing cylinder is inserted into an annular support attached to an opening formed in a plate constituting one surface of the air flow path, and is attached by screwing. The body proposes an air outlet device in which a flange portion is formed in an inner corresponding portion of the air flow path, and the blowout cylinder has a flange portion formed in an outer corresponding portion of the air flow path.

  Moreover, in this invention, it is proposed to divide | segment a cyclic | annular support body into 2 in said structure.

  In the present invention, it is proposed that, in the above-described configuration, a notch is formed in a part of the annular support body.

  In the present invention, it is proposed that the air flow path is a corrugated air conditioning duct in the above configuration.

  In the air blowout device of the present invention, the conditioned air flowing through the air flow path is blown out by attaching the blowout cylinder to the inside from the opening formed in the plate constituting one surface of the air flow path. It can be blown out directly into the air-conditioned space through the cylinder.

  At this time, since the blowing cylinder has an inclined opening formed in the inner corresponding portion protruding into the air flow path, the inclined opening of the conditioned air flows in the air flow path. By changing the direction, the amount and direction of the conditioned air blown out from the blowing cylinder can be adjusted.

  In addition, since the inner corresponding portion in which the inclined opening is formed protrudes into the air flow path, it has a rectifying effect on the air flow blown out from the blowing cylinder, and also against the air flow in the air flow path. The airflow distribution when the plurality of blowing cylinders are provided along the flow direction of the conditioned air in the air flow path is made uniform as the static resistance distribution in the air flow path is made uniform by increasing the ventilation resistance. Uniformity can be achieved.

  If the blowing cylinder is inserted into an annular support attached to an opening formed in a plate constituting one surface of the air flow path and is attached by screwing, at least the blowing cylinder is connected to the air flow path. It can be installed after assembling and can be expanded as necessary.

  If the annular support is divided into two parts or a notch having a gap is formed, the annular support can be attached to the opening after the air channel is assembled.

  The air outlet apparatus of the present invention is very lightweight because it does not use blades or shutters for adjusting the air volume and direction, and can be well applied to a corrugated duct as an air flow path. In addition, the air flow path can be significantly reduced in weight. Further, the structure is simple and the cost can be reduced.
