And is sucked into the blower 60, in particular the orifice 66.

The air sucked into the orifice 66 is blown while forming a whirlwind to the top of the blowing fan 64.

After the air of the vortex blown to the upper part of the blowing fan 64 is discharged to the upper side of the orifice 66, the bracket hole 164 of the head rotating unit bracket 160 and the head 20, in particular the head base It passes through the head hole 101 of the panel 110 in sequence and is sucked into the head 20.

The air sucked into the head 20 is discharged to the outside of the head 20 through the first, second, and third discharge ports 21, 22, 23.

At this time, the discharge airflow discharged from the head 20 is open in all directions because all of the first, second, and third discharge ports 21, 22, 23 are opened, and the head 20 is reciprocally rotated in the left and right directions. It can disperse quickly and flow dynamically.

Alternatively, as shown in FIGS. 5 to 10, as another example of the operation of the indoor unit 1 of the air conditioner, the head 20 is rotated, and the first, second, and third discharge ports 21, 22 ( When a part of 23) is operated to open and the rest to close, the indoor unit 1 of the air conditioner is operated as follows. Hereinafter, for convenience of description, only the first discharge port 21 of the first, second and third discharge ports 21, 22 and 23 is opened and the second and third discharge ports 22 and 23 are closed. Explain.

In the operating conditions of the indoor unit 1 of the air conditioner as described above, as in the operation example of the indoor unit 1 of the air conditioner described above, the air is blown into the cabinet 10 by the blowing force of the blower 60. After is sucked in, it is cooled or heated by the heat exchanger 70, and the cooled or heated air is sucked into the head 20.

The air sucked into the head 20 is opened only through the first discharge port 21 and the second and third discharge ports 22 and 23 are closed. Only through the opened first discharge port 21. It is discharged to the outside of the head 20.

At this time, since the head 20 is reciprocally rotated in the left and right direction, it is quickly dispersed in all directions and a dynamic discharge airflow is formed, of course, only the first discharge port 21 is opened and the second and third discharge ports 22 ( Since 23 is closed, the concentrated discharge airflow and the remote discharge airflow can be formed through the first discharge port 21.

Alternatively, as shown in FIGS. 5 to 9 and 11, as another operation example of the indoor unit 1 of the air conditioner, the head 20 is not rotated and the first, second, and third discharge ports are not rotated. When both of the (21), (22), and (23) are operated to open, the indoor unit (1) of the air conditioner is operated as follows.

In the operating conditions of the indoor unit 1 of the air conditioner as described above, as in the operation example of the indoor unit 1 of the air conditioner described above, the air is blown into the cabinet 10 by the blowing force of the blower 60. After is sucked in, it is cooled or heated by the heat exchanger 70, and the cooled or heated air is sucked into the head 20.

The air sucked into the head 20 is rapidly distributed and discharged in all directions through the first, second, and third discharge ports 21, 22, 23. In this case, the head 20 is not rotated. Static discharge airflow is formed than when the head 20 is rotated, thereby creating a calm indoor environment.

Alternatively, as shown in FIGS. 5 to 9 and 12, as another example of operation of the indoor unit 1 of the air conditioner, the head 20 is not rotated and the first, second, and third discharge ports ( When a part of 21) (22) (23) is operated to open and the rest to close, the indoor unit 1 of the air conditioner is operated as follows. Hereinafter, for convenience of description, only the first discharge port 21 of the first, second and third discharge ports 21, 22 and 23 is opened and the second and third discharge ports 22 and 23 are closed. Explain.

In the operating conditions of the indoor unit 1 of the air conditioner as described above, as in the example of the operation of the indoor unit 1 of the air conditioner described above, into the cabinet 10 by the blowing force of the blower 60. After the air is sucked in, it is cooled or heated by the heat exchanger 70, and the cooled or heated air is sucked into the head 20.

The air sucked into the head 20 is only the first discharge port 21 is opened, the head 20 is not rotated, the central discharge through the first discharge port 21 concentrated to a specific place intensively .

At this time, the head 20 may be stopped by rotating the driving force of the head rotating unit motors 190 and 192 so that the first discharge port 21 faces a specific place.

Alternatively, as shown in FIGS. 5 to 9, as another example of the operation of the indoor unit 1 of the air conditioner, the head 20 is applied to the sensing results of the infrared sensors 27, 28, 28. Rotation can be controlled accordingly. In this case, the first, second, and third discharge ports 21, 22, 23 may be all open or only partially open according to the sensing result of the infrared sensors 27, 28, 29.

That is, as a result of sensing by the infrared sensors 27, 28, 29, when the temperature distribution of a specific part of the room is relatively higher, the first, second, and third discharge ports 21, 22, 23 are discharged intensively. Only a part (for example, the first discharge port 21) is opened to form an air flow, and the head 20 is the open discharge port among the first, second and third discharge ports 21, 22, 23. For example, the first discharge port 21 may be rotationally controlled to face a relatively higher temperature distribution.

Then, since the discharge air flow is concentrated to a place where the temperature distribution is higher, the temperature change is changed rapidly in a place where the temperature distribution is higher, so that the room can be cooled and heated quickly and evenly.
