[0045] There are two first guide structures, which correspond to the horizontal positions of the first drive mechanism 4 and the second drive mechanism 4 respectively; the guide rails in the two first guide structures are concentric arcs, which facilitates smoother pushing out and retracting of the air inlet panel.

[0046] And / or, the guide structure includes a second guide structure; the second guide structure includes a second guide rail; the second guide rail is close to the bottom plate relative to the top plate; the bending angle of the second guide rail is smaller than the bending angle of the rack; so that the lower end of the air inlet panel 2 will not interfere with the inside of the shell 1 during movement.

[0047] There are two second guide structures, which respectively correspond to the positions of the two first guide structures in the vertical direction; the guide rails in the two second guide structures are concentric arcs, which facilitates smoother pushing out and retracting of the air inlet panel.

The travel switch 71 is provided on the mounting portion 41. The driving device 411 and the gear 412 are provided on the mounting portion 41. The driving device 411 is a motor; the driving device 411 drives the gear 412 to rotate, drives the rack 421 to move, and drives the air inlet panel 2 to move.

[0049] Furthermore, a limit member 72 is provided on the air inlet panel 2; when the lower end of the rack is engaged with the first toggle portion, the limit member 72 contacts the travel switch 71, and the travel switch 71 controls the driving device 411 to be closed.

[0050] Furthermore, a limit member 72 is provided on the mounting member 42; when the air inlet panel 2 is in the open position, the limit member 72 contacts the travel switch 71, and the travel switch 71 controls the driving device 411 to be closed. The driving device 411 is a motor; when the motor rotates, the rack 421 on the mounting member 42 is meshed with the gear on the mounting portion 42, and the movable portion 413 rolls and slides on the guide rail 422 respectively. In the initial state, as shown in FIG. Figure 6 When the air inlet panel 2 is open, Figure 5 As shown; when the machine is turned on and the air inlet panel 2 is pushed open, the limit member 72 contacts the travel switch 71, the motor receives a signal and stops rotating randomly, and the air inlet panel 2 is pushed out into place.

[0051] The movable part 413 is a roller; the limiting part 72 is a limiting rib; the mounting part 42 is a push plate; the push plate is connected to the inner surface of the air inlet panel 2 and is angled; the push plate extends from top to bottom; each driving mechanism 4 is provided with a push plate; each push plate is provided with a shaft hole at the upper and lower ends, and the two shaft holes are respectively connected to the corresponding positions of the upper and lower ends of the air inlet panel 2 through the shaft.

[0052] Furthermore, the air conditioner indoor unit also includes an air guide plate 5; the air guide plate 5 is arranged at the air outlet; the air guide plate 5 is an arc-shaped plate, which can best achieve the air guiding effect.

[0053] Furthermore, the chord length of the arc plate is B; the arc height of the arc plate is C; wherein, B=85-110 mm; and / or, C=5-10 mm; under these parameters, the airflow can be blown farther and more comfortably.

[0054] Furthermore, the air conditioner indoor unit also includes a pushing mechanism; the pushing mechanism is used to push the air guide plate 5 to move along the central axis direction of the air outlet; the air guide plate 5 is rotatably connected to the pushing mechanism; when the air guide plate 5 is rotated to a position perpendicular to the air outlet, the maximum distance between the air guide plate 5 and the back plate is A; when the air guide plate 5 is rotated to be parallel to the air outlet, the maximum distance between the air guide plate 5 and the air outlet is D; and / or, A = 30mm~68mm; and / or, D = 40~50mm. The pushing mechanism pushes the air guide plate 5 out of the air outlet as the pushing position; the pushing mechanism pushes the air guide plate 5 to close the air outlet as the closed position; the air guide plate 5 is movable between the pushing position and the closed position. Its velocity cloud diagram during cooling is as follows: Figure 7As shown, when D=40~50mm, the cooling effect is optimal. At this time, the air guide plate is in a horizontal position. It can be seen that the simulated airflow reaches the entire room. If it is pushed too large or too small, the cold air cannot reach the entire room. When heating, the air guide plate rotates to a position perpendicular to the air outlet, and the hot air blows downward. A=30mm~68mm can make the airflow fill the entire room as quickly as possible. If the distance A is too small, it may cause the airflow to blow toward the wall. If the distance is too large, the airflow cannot flow to the back of the air guide plate, resulting in poor heating effect. Because the air guide plate is made into an arc, the airflow blows a longer distance along the arc-shaped air guide plate, and the comfort is better. The airflow organization and velocity cloud diagram are shown as follows Figure 8 , Fig. 9 shown.
