By controlling the rotation angle of the gear plate 4, the opening degree of the wind deflector 7 can be controlled to achieve the cooling state and the cold air is sent upward. When heating, the upper motor 61 controls the upper buckle 1 to hook the upper buckle 70 of the air deflector 7, and the lower motor 62 drives the lower buckle 1 to be disengaged from the lower buckle 71 of the air deflector 7, at this time, the gear disc 4 is in the motor 60. The pinion 5 is driven to rotate, and the air guiding plate 7 is pushed by the movable hinged link 3 to rotate the connecting line of the upper buckle 70 on the left and right sides of the air guiding plate 7 as a rotating shaft, and the motor 60 passes through the control gear wheel 4.

 When the air conditioner 1 is in the closed state, each of the inner air deflector 31 and the outer air deflector 32 is in the closed position.

 When the air conditioner 1 enters the cooling mode, each of the inner air deflector 31 and the outer air deflector 32 pivots counterclockwise from the closed position to the upper air guiding position.

 When the air conditioner 1 enters the heating mode, the inner air deflector 31 pivots counterclockwise from the closed position to the lower air guiding position, and the outer air deflector 32 pivots clockwise from the closed position Lower guide air position.

 In other words, when the air conditioner 1 is in the cooling mode, the inner air deflector 31 and the outer air deflector 32 may be located at the upper air guiding position. When the air conditioner 1 is in the heating mode, the inner air deflector 31 and the outer air deflector 32 may be located at the lower air guiding position.

Specifically, when the air conditioner 1 enters the cooling mode, the air deflector 30 is pivoted from the closed position to the upper air guiding position. Specifically, the inner air deflector 31 and the outer air deflector 32 pivot relative to the air outlet frame 20, and the inner air deflector 31 and the outer air deflector 32 are pivoted from the closed position to the upper air guiding position. The deflector 31 and the outer deflector 32 may be relatively stationary (the inner deflector 31 and the outer deflector 32 are pivoted counterclockwise from the position shown in FIG. 8 to the position shown in FIG. 9). When the air conditioner 1 enters the heating mode, the air deflector 30 is pivoted from the closed position to the lower air guiding position. Specifically, the inner air deflector 31 and the outer air deflector 32 pivot relative to the air outlet frame 20 and the outer air guide panel 32 pivots relative to the inner air deflector 31, and the inner air deflector 31 and the outer air deflector 32 are The closed position is pivoted to the lower air guiding position (the inner deflector 31 and the outer deflector 32 are pivoted from the position shown in FIG. 8 to the position shown in FIG. 11), and the inner deflector 31 is counterclockwise The outer deflector 32 is pivoted clockwise. Specifically, the inner air deflector 31 and the outer air deflector 32 can be pivoted at the same time, and the outer air deflector 32 can also pivot to the transition position shown in FIG. 10 with the inner air deflector 31, and then the inner guide. The wind plate 31 pivots.

 In a specific example of the present invention, the control method of the air conditioner 1 includes the following steps:

Describe the position of the wind guide. When the air conditioner 1 exits the cooling mode, the first drive motor 40 rotates 40 degrees clockwise, that is, the first drive motor 40 drives each of the inner air deflector 31 and the outer air deflector 32 to rotate clockwise by 40 degrees. Describe the closed position.

 When the air conditioner 1 enters the heating mode, the first drive motor 40 rotates counterclockwise by 97 degrees, that is, the first drive motor 40 drives each of the inner air deflector 31 and the outer air deflector 32 to rotate counterclockwise by 97 degrees. At this time, the inner air deflector 31 is located at the lower air guiding position. Then, the second drive motor 50 is rotated 174 degrees clockwise, that is, the second drive motor 50 drives the outer air guide plate 32 to rotate clockwise by 174 degrees, at which time the outer air guide plate 32 is located at the lower air guide position. When the air conditioner 1 exits the heating mode, the second drive motor 50 rotates 174 degrees counterclockwise, that is, the second drive motor 50 drives the outer air deflector 32 to rotate counterclockwise by 174 degrees, and then the first drive motor 40 rotates clockwise 97. That is, the first drive motor 40 drives each of the inner deflector 31 and the outer deflector 32 to rotate clockwise by 97 degrees to the closed position.

 Further, the air conditioner 1 can also be switched between the upper air guiding mode and the lower air guiding mode, i.e., the air guiding plate 30 can be pivoted between the upper air guiding position and the lower air guiding position. When the air guiding plate 30 is pivoted from the upper air guiding position to the lower air guiding position, the inner air guiding plate 31 and the outer air guiding plate 32 pivot relative to the air guiding frame 20 and the outer air guiding plate 32 is opposite to the inner guiding portion. The wind plate 31 pivots, and the inner air deflector 31 and the outer air deflector 32 are pivoted from the upper air guiding position to the lower air guiding position. Specifically, the inner air deflector 31 and the outer air deflector 32 can be pivoted simultaneously (the inner air deflector 31 and the outer air deflector 32 are pivoted from the position shown in FIG. 9 to the position shown in FIG. The air deflector 31 pivots counterclockwise and the outer air deflector 32 pivots clockwise. The outer air deflector 32 can also pivot first with the inner air deflector 31 and then pivot relative to the inner air deflector 31 (internal wind guide) The plate 31 and the outer air deflector 32 are pivoted from the position shown in FIG. 9 to the position shown in FIG. 10, and then pivoted to the position shown in FIG. 11, and the inner air deflector 31 pivots counterclockwise and guides the wind. The plate 32 is pivoted counterclockwise and then pivoted clockwise). In Fig. 10, the inner air deflector 31 is located at the lower wind guide position.

 The process of pivoting the inner air deflector 31 and the outer air deflector 32 from the lower air guiding position to the upper air guiding position and the inner air guiding plate 31 and the outer air guiding plate 32 are pivoted from the upper air guiding position The process to the lower wind guide position is reversed and will not be described in detail herein.

 In other words, the inner air deflector 31 and the outer air deflector 32 are pivotally disposed on the air outlet frame 20 between the closed position, the upper air guiding position and the lower air guiding position, and the outer air guiding wind The plate 32 is pivotally disposed between the closed position and the lower air guiding position and between the upper air guiding position and the lower air guiding position on the inner wind deflector 31.

The existing air conditioner has only one air deflector (corresponding to the outer air deflector 32). Since the air deflector and the air outlet frame interfere with each other, the air deflector of the existing air conditioner cannot be moved to the lower guide.
