The top cover 14 is disposed on the top of the air outlet frame 12 , the base 13 is located at the bottom of the lower panel 162 and the rear shell 11 , and the heat exchanger component 60 and the air duct component 50 are located between the rear shell 11 and the air outlet frame 12 .

[0076] According to the air conditioner of the embodiment of the present invention, the drive motor 44 and the air guide plate 20 are driveably connected through the transmission component 4, and the transmission component 4 is driveably connected to the drive motor 44 and the switch door 30. The movement of the air guide plate 20 and the switch door 30 is achieved by sharing a drive motor 44. This can reduce the number of drive motors 44 used, making the structure of the drive mechanism 40 simple, saving costs, and saving installation space.

[0077] Reference Figure 3 and Figure 4 According to some embodiments of the present invention, the transmission assembly 4 includes a first transmission member 41, a second transmission member 42 and a third transmission member 43. The first transmission member 41 is arranged on the motor shaft 441 of the driving motor 44, the second transmission member 42 is arranged on the switch door 30, and the third transmission member 43 is arranged on the air guide plate 20. The first transmission member 41 is suitable for being drivably connected with the second transmission member 42 to drive the switch door 30 to rotate, so that the driving motor 44 drives the switch door 30 to rotate, and the switch door 30 can be controlled to open or close the air outlet 122; the first transmission member 41 is suitable for being drivably connected with the third transmission member 43 to drive the air guide plate 20 to rotate, so that the driving motor 44 drives the air guide plate 20 to rotate, and the air guide plate 20 can be controlled to adjust the air outlet. Therefore, the movement of the air guide plate 20 and the switch door 30 is achieved by sharing a driving motor 44, which can reduce the number of driving motors 44 used, making the structure of the driving mechanism 40 simple and saving costs.

[0078] Reference Fig.21 and Fig. 27According to some optional embodiments of the present invention, the first transmission member 41 includes a first rotating shaft 410, a first meshing portion 411 and a second meshing portion 412, the first meshing portion 411 and the second meshing portion 412 are fixed to the first rotating shaft 410, the first rotating shaft 410 is connected to a motor shaft 441, the motor shaft 441 can drive the first rotating shaft 410 to rotate, and the rotation of the first rotating shaft 410 can drive the first meshing portion 411 and the second meshing portion 412 to rotate. For example, a motor shaft hole 413 is formed in the first rotating shaft 410, and the motor shaft 441 is suitable for being inserted into the motor shaft hole 413, so that the motor shaft 441 is connected to the first rotating shaft 410.

[0079] Reference Figure 6-Figure 15 , the first meshing portion 411 is adapted to mesh with the second transmission member 42, so that the first transmission member 41 and the second transmission member 42 can be connected in transmission to drive the switch door 30 to rotate; the second meshing portion 412 is adapted to mesh with the third transmission member 43, so that the first transmission member 41 and the third transmission member 43 can be connected in transmission to drive the air guide plate 20 to rotate. The projection of the first meshing portion 411 on the reference plane is the first projection, and the projection of the second meshing portion 412 on the reference plane is the second projection. The first projection and the second projection are arranged at intervals in the circumferential direction of the first rotating shaft 410, and the reference plane is perpendicular to the axial direction of the first rotating shaft 410. For example, the axial direction of the first rotating shaft 410 can refer to the up and down direction in the accompanying drawings, and the reference plane can be a horizontal plane. The first projection and the second projection are arranged at intervals in the circumferential direction of the first rotating shaft 410, so that the first meshing portion 411 and the second meshing portion 412 are spaced apart, so that the first meshing portion 411 and the second meshing portion 412 do not affect each other.

[0080] Reference Figure 4 and Fig.19 In some optional embodiments of the present invention, the housing assembly 10 is provided with a second rotating shaft 13, the second transmission member 42 and the third transmission member 43 are both rotatably sleeved on the second rotating shaft 13, and the second transmission member 42 and the third transmission member 43 are arranged along the axial direction of the second rotating shaft 13, and the first meshing portion 411 and the second meshing portion 412 are arranged along the axial direction of the first rotating shaft 410. The second transmission member 42 and the third transmission member 43 can both rotate along the axial direction of the second rotating shaft 13, and the rotation axis of the second transmission member 42 and the rotation axis of the third transmission member 43 are coaxially arranged, and the rotation axis of the air guide plate 20 and the rotation axis of the switch door 30 are coaxially arranged, so that the air guide plate 20 and the switch door 30 can rotate around the same rotation center, and the overall structure is compact, which can save space.

[0081] Furthermore, the projection of the first meshing portion 411 on the reference plane is the first projection, and the projection of the second meshing portion 412 on the reference plane is the second projection. The first projection and the second projection are spaced apart in the circumferential direction of the first rotating shaft 410. When the first meshing portion 411 is meshed with the second transmission member 42, the first meshing portion 411 is disengaged from the third transmission member 43; when the second meshing portion 412 is meshed with the third transmission member 43, the first meshing portion 411 is disengaged from the second transmission member 42. Thus, the first transmission member 41 can be prevented from simultaneously driving the second transmission member 42 and the third transmission member 43 to move, thereby realizing that a single drive motor 44 drives the air guide plate 20 and the switch door 30 to move respectively, and the movements of the air guide plate 20 and the switch door 30 are relatively independent.

[0082] For example, refer to Fig.19 and Fig.23 A first shaft hole 421 is formed on the second transmission member 42, and a second shaft hole 431 is formed on the third transmission member 43. The second rotating shaft 13 can be inserted into the first shaft hole 421 and the second shaft hole 431, so that the second transmission member 42 and the third transmission member 43 can be rotatably sleeved on the second rotating shaft 13. The axial direction of the second rotating shaft 13 can refer to the up and down direction in the accompanying drawing.

[0083] Reference Figure 4 In some optional embodiments of the present invention, the axial direction of the first rotating shaft 410 is arranged parallel to the axial direction of the second rotating shaft 13, and the rotation axis of the first transmission member 41 is parallel to the axial direction of the second rotating shaft 13, so that the first transmission member 41 directly drives the second transmission member 42 and the third transmission member 43 to rotate axially around the second rotating shaft 13, thereby realizing the axial rotation of the switch door 30 and the air guide plate 20 around the second rotating shaft 13, without the need to add an additional transmission structure.

[0084] Reference Fig.19 , Fig. 27 and Fig.28 In some optional embodiments of the present invention, the second rotating shaft 13 includes a first shaft portion 131 and a second shaft portion 132, the first shaft portion 131 and the second shaft portion 132 are arranged along the axial direction of the second rotating shaft 13, a limited step surface 133 is formed between the first shaft portion 131 and the second shaft portion 132, the second transmission member 42 is sleeved on the first shaft portion 131, and the third transmission member 43 is sleeved on the second shaft portion 132. The second transmission member 42 is limited by the limited step surface 133, which reduces the displacement of the second transmission member 42 along the axial direction of the second rotating shaft 13, improves the stability of the second transmission member 42, and further improves the movement stability of the switch door 30; the second transmission member 42 and the third transmission member 43 can also be spaced apart along the axial direction of the second rotating shaft 13, which reduces the contact wear between the second transmission member 42 and the third transmission member 43, and helps to reduce noise.

[0085] For example, refer to Fig.19The axial direction of the second rotating shaft 13 is the up-down direction, and the first shaft portion 131 is located on the upper side of the second shaft portion 132. The radial dimension of the first shaft portion 131 is smaller than the radial dimension of the second shaft portion 132. A first shaft hole 421 is formed on the second transmission member 42, and a second shaft hole 431 is formed on the third transmission member 43. The radial dimension of the first shaft hole 421 is smaller than the radial dimension of the second shaft hole 431. The second transmission member 42 is sleeved on the first shaft portion 131, and the bottom surface of the second transmission member 42 abuts against the limiting step surface 133 to limit the second transmission member 42.

[0086] Reference Fig.19 and Figure 31-Figure 33 In some optional embodiments of the present invention, the second rotating shaft 13 further includes a mounting protrusion 134 and a first limiting protrusion 135.
