The link 42 and the rotating arm 43 are rotatably connected to the arm 43, and the link 42 and the rotating arm 43 are provided in a link case 44, and the other end of the rotating arm 43 extends from the link case 44 and is pivotally connected to the outer wind direction plate 3. be done. The motor 41 may be directly connected to the link 42, but a large motor driving force is required. The connection between the motor 41 and the transmission assembly 45 allows the transmission assembly 45 to be connected to the link 42 to amplify the motor driving force, thereby reducing the cost of the motor 41.

In some alternative embodiments, as shown in FIG. 15, the transmission assembly 45 includes a first gear 451, a second gear 452, and a third gear 453 and a fourth gear 454 that are coaxially arranged . The first gear 451 is fitted onto the motor shaft of the motor 41, the second gear 452 is connected to the rotating shaft of the link 42 and drives the rotation of the link 42, and the third gear 453 is connected to the first gear 451. The fourth gear 454 meshes with the second gear 452. This effectively ensures the transmission efficiency of the transmission assembly 45.

More selectively, the outer diameters D1, D2, D3, and D4 of the first gear 451, the second gear 452, the third gear 453, and the fourth gear 454 satisfy D4<D1<D2<D3. In this way, the driving force of the outer drive device 4 can be easily amplified, and the cost of the motor 41 can be reduced. Of course, the present disclosure is not limited thereto. Using the transmission assembly 45, the number of gears used and the ratio of their outer diameters can be determined according to the specific design.

In some further embodiments of the present disclosure, as shown in FIGS. 13 and 16-19, the outer wind direction plate 3 has a sliding part 35 on the inner surface, and as shown in FIG. Slide portions 35 are provided at both left and right ends of the surface. A slide member 36 having a slide rod 361 is slidably provided on the slide portion 35, the rotary arm 43 has an insertion hole 431 at the other end, and the slide rod 361 is rotatably inserted into the insertion hole 431.

In other words, the two extension pieces 3632 extend in a direction facing the outside of the air conditioning indoor unit 100. The distance between the two extension pieces 3632 is smaller than the diameter of the extension column 3631. This prevents the extension column 3631 from falling off and secures the fixation robustness of the extension column 3631. Positioning slot 362 is defined by extension piece 3632 and slide member 36 .

As shown in FIGS. 17 and 19, when attaching the outer wind direction plate 3 and the outer drive device 4, the slide member 36 is moved toward the center of the outer wind direction plate 3, and the position of the slide rod 361 is adjusted to the outer side wind direction plate 3. When aligned with the hole on the side plate, the slide member 36 is pushed onto the rotating arm 43 , and the rotating arm 43 is hingedly connected to the outer wind direction plate 3. At the time of removal, the slide member 36 may be strongly pushed in the direction away from the rotating arm 43 . Specifically, as shown in FIG. 19, a positioning portion 363 is provided on the back surface of the slide member 36, and a positioning slot 362 is defined by the positioning portion 363 and one side of the slide member 36.

In some alternative embodiments, as shown in FIG. At the same time, the weight of the outer wind direction plate 3 is reduced, and the weight of the outer wind direction plate 3 is reduced.

According to the air conditioning indoor unit 100 according to the embodiment of the present disclosure, as shown in FIG. It is larger than the distance L1 between the lower end of the mounting portion of the plate 3 and the wall. In this way, when the air conditioning indoor unit 100 is operating, the air from the outlet 111 is blown away from the wall, reducing the amount of wind flowing through the gap between the attachment part of the outer wind direction plate 3 and the outer wind direction plate 3 . This reduces condensation on the front side of the outer wind direction plate 3.

The radian of 22 is larger than the radian of the inner front panel 21, and effectively ensures the strength of the inner wind direction plate 2.

In some alternative embodiments, as shown in FIGS. 3 and 8 , the upper end of the inner wind deflection plate 2 is configured with an arcuate end, so that the inner wind deflection plate 2 is pivoted to the first receiving part 11. Effectively ensures that it is movably fixed. The extension length of the inner rear panel 22 is shorter than the extension length of the inner front panel 21, and the lower end of the inner front panel 21 is bent rearward to cover the lower end of the inner rear panel 22. The bending angle of the lower end of the inner front panel 21 satisfies 30 degrees or more and 80 degrees or less (including boundary values), and is selectively about 60 degrees, but is not limited thereto. This makes it easy to integrally mold the inner rear panel 22 and the inner front panel 21, and the processing is simple.

In some selective embodiments, at least one of the inner rear panel 22 and the inner front panel 21 is provided with a plurality of parallel inner plate patterns 23 extending in the left-right direction. In the examples shown in FIGS. 3 and 8, an inner plate pattern 23 is provided on the rear surface of the inner rear panel 22, and an inner plate pattern 23 is provided on the front surface of the inner front panel 21, thereby controlling the direction of airflow.

As shown in FIGS. 3 and 8, when the inner wind direction plate 2 is closed, its upper end is thicker than its lower end. This effectively ensures the strength of the inner wind direction plate 2 and prevents the inner wind direction plate 2 from breaking during rotation. Note that when the inner wind direction plate 2 is closed, one end facing the outside of the air conditioning indoor unit 100 and located at a relatively high position is referred to as the "upper end" (i.e., pivoting end), and faces the inside of the air conditioning indoor unit 100. One end at a relatively low position is referred to as a "lower end" (ie, free end).

As shown in FIG. 4, the first housing part 11 includes a first arc panel 112, a first left side plate 113, and a first right side plate 114. The first arc panel 112 is located on one side of the housing 1, and the first arc panel 112 is convex toward the rear . This ensures that the arc shape of the first arc panel 112 matches the inner wind direction plate 2, improves the degree of adhesion with the first arc panel 112 when the inner wind direction plate 2 is closed, and The gap between the outer cover 13 and the outer cover 13 is reduced. The first left side plate 113 and the first right side plate 114 are respectively located on the left and right sides of the first arc panel 112, and the three define a first accommodation space, and the inner wind direction plate 2 is located within the first accommodation space. Pivotably located.
