First and second limiting ends 411 and 412 are arranged at opposite ends of the first rotating sliding groove 41.

[0065] A wind guide door 3 is arranged at the air outlet 2 and can perform bidirectional swinging movement relative to the air outlet 2.

[0066] A second driving motor 9 is arranged on the second end plate 5 and can drive the wind guide door 3 to move to the first or second limiting end 411 or 412.

[0067] A first driving motor 7 is arranged on the first end plate 4 and can drive the wind guide door 3 to perform bidirectional swinging movement relative to the air outlet 2 along a first rotating shaft at the first limiting end 411 or a second rotating shaft at the second limiting end 412.

[0068] The application discloses a wind guide mechanism with a bidirectional wind guide function, which is provided with two driving motors, i.e., a first driving motor 7 and a second driving motor 9, wherein the second driving motor 9 is used for driving a wind guide door 3 to switch movement between a first limiting end 411 and a second limiting end 412, and the first driving motor 7 is used for driving the wind guide door 3 to move along a first rotating shaft at the first limiting end 411 or a second rotating shaft at the second limiting end 412 to open an air outlet 2, so as to realize different rotating directions and rotating angles of the wind guide door 3 in the refrigeration and heating working conditions. Specifically, the first limiting end 411 is arranged above the outer side of the second limiting end 412, that is, the first rotating shaft is formed above the outer side of the second rotating shaft. In the refrigeration working condition, the second driving motor 9 can drive the wind guide door 3 to move to the first limiting end 411, and the first driving motor 7 can drive the wind guide door 3 to rotate along the first rotating shaft, so that the wind guide door 3 rotates outward from the upper side, thereby realizing upward air outlet of the air outlet 2 under the action of the wind guide door 3 in the refrigeration working condition. In the heating working condition, the second driving motor 9 can drive the wind guide door 3 to move to the second limiting end 412, and the first driving motor 7 can drive the wind guide door 3 to rotate along the second rotating shaft, so that the wind guide door 3 rotates outward from the lower side, thereby realizing downward air outlet of the air outlet 2 under the action of the wind guide door 3 in the heating working condition. Since the wind guide door 3 rotates along the two rotating shafts in the refrigeration and heating working conditions respectively, the wind guide plate can adapt to different wind guide angles in the heating and refrigeration working conditions, so that the wind guide mechanism realizes bidirectional wind guide in different working conditions.

[0069] The wind guide mechanism with the bidirectional wind guide function can realize different wind direction control of the air outlet in the refrigeration and heating working conditions by the combined action of the first driving motor and the second driving motor, flexibly controls the air outlet area and the wind direction, provides more personalized and comfortable air outlet experience, and improves the adaptability and performance of the system.

When the air guide door 3 is driven by the first driving motor 7, the outer ring of the rotation bearing 37 does not rotate, and the inner ring rotates, realizing the driving opening of the air guide door 3. When the air guide door 3 is driven by the second driving motor 9 for position switching, the inner ring is stationary, and the outer ring rotates, and then the gear and rack transmission structure is used to realize the position switching of the air guide door.
