The guide plate assembly includes a push rod 440 and a guide plate 30 disposed at the front end of the push rod 440, the guide plate 30 being used to guide the airflow exiting the air outlet 20. The push rod 440 is telescopically mounted on the housing 10, and includes a first pressing surface 441 and a second pressing surface. The lever 430 is slidably mounted on the housing 10. When the lever 430 slides in a first direction, the lever 430 presses against the first pressing surface 441, causing the push rod 440 to extend. When the lever 430 slides in a second direction opposite to the first direction, the lever 430 presses against the second pressing surface, causing the push rod 440 to retract. The first driving mechanism 420 is used to drive the lever to slide.

[0054] In this embodiment, when the guide plate 30 opens the air outlet 20, the first driving mechanism 420 drives the lever 430 to slide in the first direction. The lever 430 presses against the first pressing surface 441, causing the push rod 440 to extend, thereby pushing the guide plate 30 out of the air outlet 20. When the guide plate 30 closes the air outlet 20, the first driving mechanism 420 drives the lever 430 to slide in the second direction. The lever 430 presses against the second pressing surface, causing the push rod 440 to retract, thereby pulling the guide plate 30 to the air outlet 20. By driving the lever 430 to move through the first driving mechanism 420, the lever 430 presses against the first pressing surface 441 or the second pressing surface, causing the push rod 440 to extend and retract, thus pushing the guide plate 30 out of the air outlet 20. This avoids the guide plate 30 blocking the air outlet 20, thereby preventing the heat exchange air from blowing onto the guide plate 30, preventing the guide plate 30 from affecting the air outlet angle and air volume, and improving the air outlet effect of the indoor unit 100 of the air conditioner. Furthermore, the guide plate 30 is pushed out from the air outlet 20, which reduces the obstruction of the air outlet by the guide plate 30, thereby reducing the noise generated by the heat exchange air blowing to the guide plate 30.

The push rod 440 retracts backward and downward when retracting, that is, the guide plate 30 moves backward and downward, so that the air outlet 20 is closed. The push rod 440 slides in the perforations to limit the extending and retracting directions of the push rod 440, so that the extending and retracting process of the push rod 440 is stable and smooth.

[0064] In some embodiments of the utility model, as shown in Figure 2 The first driving mechanism 420 includes a first motor 421, a first gear 422 and a rack 423, and the first motor 421 is fixed on the lever 430. The first gear 422 is connected to the output end of the first motor 421, and the first gear 422 is engaged with the rack 423. The rack 423 is fixedly arranged on the shell 10.

[0065] In the embodiment, the first motor 421 drives the first gear 422 to rotate, and the rack 423 is engaged with the first gear 422 to rotate. Since the rack 423 is fixed on the shell 10, the first gear 422 moves along the extension direction of the rack 423 when rotating, thereby driving the lever 430 to move. The movement of the lever 430 drives the push rod 440 to extend and retract, so that the guide plate 30 opens or closes the air outlet 20. The first driving mechanism 420 has simple structure, high transmission precision, high transmission stability and accurate and reliable transmission.

[0066] In some embodiments of the utility model, as shown in Figure 2 The shell 10 is provided with a raised slide bar 413, and the end of the slide bar 413 extends to a protrusion 414 on both sides. The lever 430 is provided with a sliding groove which is slidably embedded with the slide bar 413.

When the guide plate 30 is rotated to a horizontal position or an upward angle, the heat exchange air is blown out of the air outlet 20, and the guide plate 30 does not affect the blowing out of the heat exchange air, avoiding the guide plate 30 affecting the air volume of the heat exchange air. The guide plate 30 also has other rotation angles to guide the blowing out of the heat exchange air, thereby preventing the heat exchange air from directly blowing on the user.

The grille holes 113 are gradually inclined downward from front to back, avoiding the mixing of the air outlet flow blown out of the lower air outlet 20 into the air inlet flow after diffusion, and improving the working efficiency of the air conditioner indoor unit 100.

[0086] In some embodiments of the utility model, as shown in Figure 6 As shown, the air inlet opening and the air outlet 20 have a spacing therebetween. After the push rod 440 is completely extended, the upper side of the guide plate 30 is at the spacing.

[0087] In the embodiment, the air inlet is above the air outlet 20, when the guide plate 30 is opened, the guide plate 30 moves upward to the limit position, and the upper side of the guide plate 30 is at the interval. Due to the blocking of the guide plate 30, the outlet air flow and the inlet air flow are not easy to mix, avoiding the outlet air flow from the air inlet into the air conditioner indoor unit 100, or avoiding the inlet air flow and the outlet air flow mixing directly blowing into the room. Therefore, the distance between the air outlet 20 and the air inlet can be designed as small as possible, so as to design the air inlet and the air outlet 20 larger, and increase the inlet area and the outlet area as much as possible, so as to solve the problem of low air conditioning efficiency caused by insufficient inlet air flow and insufficient outlet air flow.
