However, although the air circulator described in Korean Patent Registration No. 10-1191413 is installed in an indoor unit, it does not directly flow air-conditioned air and provides a function of flowing indoor air above the indoor unit to a long distance.

Since the air circulator cannot directly flow the air-conditioned air, it is not possible to intensively supply the air-conditioned air to the target area, and thus, there is a problem in that it is not possible to selectively air-condition the target area where the temperature imbalance occurs.

Meanwhile, in Korean Patent Application Laid-Open No. 10-2017-0010293, an opening is formed in the cabinet of the indoor unit, and a door unit for opening and closing the opening is disposed. The door unit of Korean Patent Application Laid-Open No. 10-2017-0010293 is movable in the front-rear direction, closes the opening when the indoor unit is not operated, and opens the opening by moving the door unit forward when the indoor unit is operated.

However, Korean Patent Laid-Open Publication No. 10-2017-0010293 (hereinafter referred to as prior art 1) discloses that the door unit is moved forward and backward to open and close the opening, but since the door unit is located in front of the open opening, it is discharged through the opening There is a problem that hinders the flow of air. That is, the opening of the door unit of the prior art 1 is not suitable for flowing air over a long distance.

In addition, Korean Patent Laid-Open Publication No. 10-2017-0010293 (hereinafter referred to as prior art 2) only advances the door to open the opening, and since the blowing fan is located inside the exterior panel, the air flowing by the blowing fan is It generates resistance with the structure inside the panel and causes a lot of flow loss to flow air over a long distance.

On the other hand, Chinese utility model 203375535 U (hereinafter referred to as prior art 3) discloses a structure capable of rotating an axial fan within a predetermined angle range. However, in the axial fan of prior art 3, since both sides of the axial fan are fixed to the rotation shaft, only motions that are rotated based on the rotation shaft disposed on both sides can be implemented. Prior art 3 has a problem in that the axial fan cannot be rotated in a direction other than that provided by the rotating shaft. That is, prior art 3 has a problem in that the rotation shaft can be rotated only in the vertical direction provided, or only in the left and right direction.

Although not shown, when steering the steering grill 3450 in a diagonal direction to the lower right with respect to the central axis C1, the moving rack 1020 of the first steering assembly 1001 is advanced, and the second steering assembly The moving rack 1020 of (1002) is advanced.

6 to 11 show the maximum movement of the moving rack 1020 of the first steering assembly 1001 or the moving rack 1020 of the second steering assembly 1002.

By adjusting the forward or reverse distance of each of the moving racks 1020, the degree of steering may be adjusted.

In addition, when the steering assembly 1000 according to the present embodiment is switched from each steering state to any other steering state, steering is performed immediately.

When the steering is changed from the left steering of FIG. 6 to the upper right diagonal direction of FIG. 11, the moving rack 1020 of the first steering assembly 1001 moves backward from the initial position, and the second steering assembly 1002 moves. The rack is advanced in the retracted position.

As described above, the steering assembly 1000 according to the present embodiment has the advantage of being able to change the steering immediately from the current steering direction to the target steering direction.

Since the steering grill 3450 can change the steering immediately, even when the indoor target area is changed in real time, it is possible to provide direct wind to the target area.

For example, when the location of an occupant is recognized in real time through a camera module and a direct wind tracking mode is selected, a direct wind can be provided to the occupant even if the occupant moves indoors.

Conversely, when the direct wind avoidance mode is selected, direct wind can be provided, avoiding the location of occupants, among regions in which the temperature difference between the target temperature and the indoor temperature is large.
