Looking at the operation of the indoor unit of the air conditioner according to the first embodiment of the present invention configured as described above are as follows.

When the indoor unit 1 of the air conditioner is stopped, as illustrated in FIG. 2, the blower 60 and the discharge 100 are not rotated, and the discharge discharge port 103 is disposed at the discharge discharge port louver. Is closed by 110.

When the indoor unit 1 of the air conditioner is operated, various operations may be performed as described below according to the selection of operating conditions of the indoor unit 1 of the air conditioner.

4 is an exploded perspective view of an indoor unit of an air conditioner according to a first embodiment of the present invention, FIG. 5 is a cross-sectional view taken along line AA of FIG. 2, FIG. 7 is a cross-sectional view taken along line CC of FIG. 2, and FIG. 10. FIG. 1 is a diagram illustrating an example of a discharge rotation mode operation of an indoor unit of an air conditioner according to a first embodiment of the present invention.

As an example of operation of the indoor unit 1 of the air conditioner, when the discharge unit 100 is operated to operate the indoor unit 1 of the air conditioner, the blower motor 62 is driven to operate the blower motor. The blowing fan 64 is rotated by the rotational driving force of 62 to generate the blowing force in the direction toward the discharge 100 in the cabinet 10.

In addition, the discharge discharge port louver motor 122 is driven, the discharge drive pinion gear 124 is rotated by the rotational driving force of the discharge discharge port louver motor 122, and the discharge drive pinion gear 124 is rotated. The discharge rack gear 126 is slid up and down by rotation of), and the discharge driven pinion gear 128 is rotated by up and down sliding of the discharge rack gear 126.

Then, the discharge discharge port louver 110 is rotated vertically toward the inside of the discharge 100 integrally with the discharge drive pinion gear 124 or the discharge driven pinion gear 128, and the discharge The discharge port 103 is opened.

At this time, the discharge discharge port louver motor 122 may be controlled to stop after the discharge discharge port 103 is fully opened.

Alternatively, the discharge outlet louver motor 122 may be controlled to stop after the discharge outlet 103 is partially opened.

Alternatively, the discharge outlet louver motor 122 may be controlled such that the discharge outlet louver 110 reciprocates in the vertical direction.

In addition, the discharge rotation unit motors 190 and 192 are driven, and the drive gears 201 and 202 are rotated by the rotation driving force of the discharge rotation unit motor 190, and the drive gear 201 is rotated. Rotation of 202 causes the driven gear 204 to rotate.

When the driven gear 204 is rotated, the discharge 100 is rotated in a horizontal direction integrally with the driven gear 204.

In this case, the discharge rotation unit motors 190 and 192 may be controlled such that the discharge 100 is continuously rotated only in one of left and right directions.

Alternatively, the discharge rotation unit motors 190 and 192 may be controlled to reciprocate while the discharge 100 alternately rotates left and right.

As such, when the blower 60 is driven, the discharge outlet 103 is opened, and the discharge 100 is rotated, air outside the cabinet 10 is blown by the blower 60. Air blown into the left inlet port 11 and the right inlet port 12 by the air, and the air blown into the left inlet port 11 and the right inlet port 12 through the left inlet port 11 and the right inlet port 12 While being sucked into the cabinet 10, the left and right prefilters 45a and 48a and the left and right high performance filters 45b and 48b are 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 in the space between the left heat exchanger 71 and the right heat exchanger 72, and then sucked into an upper portion between the left heat exchanger 71 and the right heat exchanger 72. 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 portion of the blower fan 64 is discharged to the upper side of the orifice 66, the bracket hole 164 of the discharge rotating unit bracket 160 and the discharge intake port 101. Passes sequentially and is sucked into the discharge (100).

The air sucked into the discharge 100 is discharged from the discharge outlet 103, the front discharge port 13, the left discharge port 14, and the right discharge port 15 of the discharge outlet 103 facing the discharge discharge port 103. Passed in order to be discharged to the outside of the cabinet (10).

In this case, the discharge airflow discharged from the cabinet 10 may be rapidly dispersed in all directions and may be dynamically flown since the discharge 100 is reciprocated in the left and right directions.

In addition, since the discharge airflow discharged from the cabinet 10 is discharged through some of the front discharge port 13, the left discharge port 14, and the right discharge port 14, it can be concentrated to any place, and can be discharged to a long distance. have.

FIG. 1 is a diagram illustrating an example of a discharge rotation stop mode operation of an indoor unit of an air conditioner according to a first embodiment of the present invention.

As another example of operation of the indoor unit 1 of the air conditioner, when the discharge 100 is stopped rotating, 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 discharge 100.

The air sucked into the discharge 100 is discharge discharge port of the front discharge port 13, the left discharge port 14 and the right discharge port 15, and the left auxiliary discharge port 16 and the right auxiliary discharge port 17. It is discharged through the discharge port facing the 103.

At this time, since the discharge 100 is not rotated, a static discharge airflow is formed than when the discharge 100 is rotated, thereby creating a calm indoor environment.

In addition, the discharge airflow may be concentrated to a long distance toward a specific place.

In this case, the discharge 100 may be discharged in a specific direction by adjusting the position of the discharge discharge port 103 by rotating the discharge 100 after stopping.

Is a view showing another operation example of the indoor unit of the air conditioner according to the first embodiment of the present invention.

Alternatively, as another operation example of the indoor unit 1 of the air conditioner, the rotation of the discharge 100 may be controlled to be rotated according to the sensing result of the infrared sensors 22, 23, 24.

That is, as a result of sensing by the infrared sensors 22, 23, 24, if the temperature distribution of the specific part of the room is relatively higher, the discharge 100 is stopped rotating so that the discharge airflow is directed to the specific part of the room. Can be. Of course, when the temperature distribution in the room changes, the position of the discharge discharge port 103 is adjusted so that the discharge direction of the discharge air flow is also changed.

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.

At this time, the rotation and the stop of the discharge 100 may be repeated, the rotation range or the continuous rotation time of the discharge 100, the stop time of the discharge 100 and the like, the infrared sensor 23 ( 24) may be controlled according to the detection result of 25.
