As an example of operation of the indoor unit 1 of the air conditioner, when the indoor unit 1 of the air conditioner is operated to rotate the head 20 and the discharge louver 24, the head 20 is operated. It is rotated in the left and right direction, the discharge louver 24 is rotated in the vertical direction, and the blower 60 is driven.

That is, the head motor 152 is driven, the rotational driving force of the head motor 152 is transmitted to the head 20 through the rotating shaft 151 to rotate the head 20.

In this case, the head motor 152 may be controlled such that the head 20 is continuously rotated in only one of the left and right directions, and the head 20 is reciprocated alternately in the left and right directions. It is also possible to be controlled to rotate. In addition, when the head 20 is reciprocally rotated in the left and right direction, the reciprocating rotation range of the head 20 may be set in one or more modes or may be selected by the user.

In addition, the discharge louver motor 136 is driven, the pinion gear 134 is rotated by the rotation driving force of the discharge louver motor 136, the rack gear (134) by the rotation of the pinion gear (134) 132 is moved up and down, the discharge louver shaft 24b is rotated by the vertical movement of the rack gear 132, the discharge louver 24 is reciprocally rotated in the vertical direction.

In addition, as the blower motor 62 is driven and the blower fan 64 is rotated by the rotational driving force of the blower motor 62, a blower force is generated in the direction toward the head 20 in the cabinet 10. do.

Accordingly, the outside air of the cabinet 10 is blown to the left suction port 11 and the right suction port 12 by the blowing force of the blower 60, and is blown to the left suction port 11 and the right suction port 12. Air is sucked into the cabinet 10 through the left inlet 11 and the right inlet 12, and is connected to the left and right prefilters 45a and 48a and the left and right high performance filters 45b and 48b. Is filtered.

The air sucked into the cabinet 10 passes through the heat exchanger 70 to be heat exchanged with the refrigerant in the heat exchanger 70 to be cooled / heated.

The air heated or cooled as described above is mixed between the left heat exchanger 71 and the right heat exchanger 72, and is then sucked into an upper portion between the left heat exchanger 71 and the right heat exchanger 72. It 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.

Air sucked into the head 20 is discharged to the outside of the head 20 through the discharge port 21.

At this time, the discharge airflow discharged from the head 20 is rapidly reciprocated in all directions because the head 20 is reciprocated in the left and right directions, and the discharge louver 24 is reciprocated in the vertical direction, and is three-dimensional and dynamic. Flows. Therefore, it is possible to receive a very strong blowing power.

As another example of operation of the indoor unit 1 of the air conditioner, the indoor unit 1 of the air conditioner is as follows, with the head 20 rotated in the horizontal direction and the discharge louver 24 stopped. Can be driven.

After the air is sucked into the cabinet 10 by the blowing force of the blower 60, it is cooled or heated by the heat exchanger 70, and the cooled or heated air is introduced into the head 20. Is inhaled.

The air sucked into the head 20 is discharged through the discharge port 21.

At this time, the discharge louver 24 may be stopped after rotation to adjust the vertical direction of the discharge air flow discharged through the discharge port 21.

In the operating condition of the indoor unit 1 of the air conditioner as described above, since the head 20 is rotated, the discharge airflow discharged through the discharge port 21 can be rapidly dispersed and can be three-dimensionally and dynamically flow.

As another example of operation of the indoor unit 1 of the air conditioner, the indoor unit 1 of the air conditioner has the following case when the head 20 is stopped and the discharge louver 24 is rotated in the vertical direction. Can be driven together.

After the air is sucked into the cabinet 10 by the blowing force of the blower 60, it is cooled or heated by the heat exchanger 70, and the cooled or heated air is introduced into the head 20. Is inhaled.

The air sucked into the head 20 is discharged through the discharge port 21.

At this time, the head 20 may be stopped after rotation so that the discharge airflow discharged through the discharge port 21 may be blown in a specific direction.

In the operating condition of the indoor unit 1 of the air conditioner as described above, since the head 20 is not rotated and is stopped, the discharge airflow discharged through the discharge port 21 is concentrated at a long distance toward a specific place. In addition, due to the vertical reciprocating rotation of the discharge louver 24 may be dynamically flow.

As another operation example of the indoor unit 1 of the air conditioner, the indoor unit 1 of the air conditioner may be operated as follows when the head 20 and the discharge louver 24 are stopped.

After the air is sucked into the cabinet 10 by the blowing force of the blower 60, it is cooled or heated by the heat exchanger 70, and the cooled or heated air is introduced into the head 20. Is inhaled.

The air sucked into the head 20 is discharged through the discharge port 21.

At this time, the head 20 may be stopped after rotation so that the discharge airflow discharged through the discharge port 21 may be blown in a specific direction.

In addition, the discharge louver 24 may be stopped after rotation to adjust the vertical direction of the discharge air flow discharged through the discharge port 21.

In the operating condition of the indoor unit 1 of the air conditioner as described above, when the head 20 or the discharge louver 24 is rotated because the head 20 and the discharge louver 24 are stopped without being rotated. A more static discharge airflow can be formed to create a calm indoor environment, and the discharge airflow discharged through the discharge port 21 can be concentrated at a long distance toward a specific place.

Since the indoor unit of the air conditioner according to the present invention configured as described above can be rotated on the upper side of the cabinet in which the discharge port is formed, the discharge airflow is dispersed in all directions by the rotation of the head, and the three-dimensional and dynamic As a result, the air discharged from the indoor unit of the air conditioner and the indoor air are quickly and evenly mixed to maximize the air conditioning efficiency, and the discharge airflow feeling is improved due to the dispersion of the airflow and the three-dimensional and dynamic discharge airflow.
