As described above, when the airflow is discharged to the room, the discharge form of the airflow to the room is discharged as in the following embodiment by the operation of the airflow discharge operation device 20 controlled by the signal of the air conditioning apparatus 4.

First Embodiment

As shown in FIG. 4, the airflow discharge control device 20 in which the jet straightener 50 is omitted is used to control the discharge of airflow.

At the time of heating-in the case of forming a vertical blowout airflow, the actuator 21 of the airflow discharge manipulation device 20 is operated to interlock the link unit 30. As shown in FIG. 9C, the link part 30 raises the guide ring 54 installed in the connection link 34 and is positioned at the lower end of the discharge nozzle 12.

Accordingly, the air flow pivoting through the twist vane 8 of the outlet case member 6 has a guide ring 57 extending downward as the discharge nozzle 12 is blocked by the flange portion 55. It is guided and discharged downward in the vertical airflow state. At this time, the vertical reach of the air flow to the room is formed within the range of 3 ~ 10m.

When cooling-When forming a horizontal blower airflow, the link unit 30 is interlocked by operating the actuator 21 of the airflow discharge operation device 20. The link portion 30 lowers the guide ring portion 54 provided in the connection link 34 to be spaced apart from the discharge nozzle 12 side as shown in FIG. 9 (a) (b).

Accordingly, the air flow turning through the twist vane 8 of the outlet case member 6 moves along the discharge nozzle 12 side by the lowering of the guide ring portion 54 to the flange portions 55 spaced apart. The bumped part spreads horizontally and the other part is guided by the guide ring 57 and discharged vertically.

Second Embodiment

As shown in (a) (b) (c) of FIG. 9, the airflow is controlled using the airflow discharge operation device 20 provided with the jet straightener 50.

At the time of heating-in the case of forming a vertical blowout airflow, the actuator 21 of the airflow discharge manipulation device 20 is operated to interlock the link unit 30. As shown in FIG. 9C, the link unit 30 raises the guide ring 54 provided in the link link 34 and is positioned at the lower end of the discharge nozzle 12.

The guide ring 54 blocks the discharge nozzle 12 side, and the jet straightener 50 covers the entire outlet passage of the outlet case member 6 and the tube core 10.

Accordingly, the air flow passing through the variable turning blowout opening S through the twist vane 8 and the tube core 10 of the blowout outlet case member 6 is guide ring 57 for blocking the discharge nozzle 12 side. And by passing through the guide of the jet straightener 50 is formed a long reach. That is, the air flow is guided by the lattice hole 52H formed by the predetermined thickness t when passing through the jet straightener 50, and the discharge distance becomes long.

As the air flow forms a long reach by indoor discharge, heat is rapidly exchanged with the indoor air, so that the indoor temperature is quickly leveled.

At this time, the vertical reach of the air flow to the room is formed within the range of 25m.

When cooling-When forming a horizontal blower airflow, the link unit 30 is interlocked by operating the actuator 21 of the airflow discharge operation device 20. As shown in (a) and (b) of FIG. 9, the link portion 30 lowers the guide ring portion 54 provided in the link link 34 at the lower end of the discharge nozzle 12.

Accordingly, the airflow turning through the twist vane 8 of the outlet case member 6 is separated by the guide ring 57 which is blocking the discharge nozzle 12 side by falling down and spaced apart. As the flange portion 55 forms a resistance wall, most of the flange portion 55 is discharged horizontally along the discharge nozzle 12.

The remaining air flow is blown out in a vertical state only through a grating hole 52H formed in the jet straightener 50.

The airflow discharged through the discharge nozzle 12 and the jet straightener 50 described above has a long reach, so that the air temperature is spread widely on the floor of the room, thereby quickly leveling the room temperature.

In addition, in the transition season, the airflow is generated by appropriately spaced apart the interval between the guide ring 54 and the jet straightener 50 from the lower end of the discharge nozzle 12 through the control of the actuator 21 so as to form a 45 ㅀ air flow. Can be taken out.

Further, as shown in Figs. 10A, 10B, and 8C, a lattice hole 52H is formed between the core case 10 and the outlet case member 6 which forms the highly variable swing ejection outlet S. The formed grid plate 52p may be further installed.

The grating plate 52p provided between the outlet port case member 6 and the core tube 10 functions as the jet straightener 50 in a fixed state regardless of the structure of the core tube 10.

The grating plate 52p provided between the outlet port case member 6 and the core tube 10 allows the airflow to be blown out vertically so that the reach length is increased to quickly level the room temperature.

The present invention is to allow the air flowing through the ceiling duct to be discharged into the room in a variety of forms from the ceiling by the air flow discharge operation device installed in the high and low variable swing outlet, to improve the air conditioning efficiency and to make the indoor air comfortable, building and office Widely used in the air conditioning industry of space.
