The gear 11 can be meshed with the first rack 214 or the second rack 215 to drive the first rack 214 or the second rack 215 to rotate, and when the gear 11 drives the first rack 214 to rotate, the gear 11 and the second rack 215 are not in a meshed state; when the gear 11 drives the second rack 215 to rotate, the gear 11 is not engaged with the first rack 214. The first rack 214 is mainly used for enabling the air deflector 30 to be in an upward opening state, the second rack 215 is mainly used for enabling the air deflector 30 to be in a downward opening state, the rack connecting plate 20 mainly plays a role in transmission, and as the first rack 214 and the second rack 215 are installed on the rack connecting plate 20 and the rack connecting plate 20 is connected with the air deflector 30, when the first rack 214 or the second rack 215 moves under the driving of the gear 11, the air deflector 30 will also move along with the first rack 214 or the second rack 215.

As an example, the first rack 214 and the second rack 215 are both arc-shaped structures, a first end of the first rack 214 is close to a first end of the second rack 215, and a second end of the first rack 214 is far from a second end of the second rack 215. The gear 11 is located at first ends of the first and second racks 214 and 215 in an initial state while being engaged with the first and second racks 214 and 215, as shown in fig. 1. At this time, the air guide plate 30 is in a closed state. When the first rack 214 or the second rack 215 needs to be driven by the gear 11, the gear 11 is rotated in the corresponding driving direction and is disengaged from the other rack, and when the air deflector 30 needs to be closed or the air deflector 30 needs to be opened in the other direction, the gear 11 is rotated in the direction opposite to the initial driving direction.

The movement principle of the embodiment of the present disclosure is explained below with reference to fig. 1 to 3.

The teeth of the first rack 214 and the second rack 215 are both arranged on the convex surface of the arc-shaped structure, the first ends of the first rack 214 and the second rack 215 are both located at the middle lower part of the rack connecting plate 20, the first rack 214 is arc-shaped and extends towards one end of the rack connecting plate 20, the second rack 215 is arc-shaped and extends towards the other end of the rack connecting plate 20, namely, the first end of the first rack 214 is close to the first end of the second rack 215, and the second end of the first rack 214 is far away from the second end of the second rack 215. The arc center of the first rack 214 is located below one side of the rack attachment plate 20, and the arc center of the second rack 215 is located below the other side of the rack attachment plate 20. The rack coupling plate 20 may rotate around the arc center of the first rack 214 and the arc center of the second rack 215, respectively, and the gear 11 is located at the first ends of the first rack 214 and the second rack 215 in the initial state.

In practice, the gear 11 is engaged with the first rack 214 and the second rack 215 at the same time in the initial state. When the air deflector 30 is required to be in an upward opening state, the gear 11 is rotated in a first direction from an initial state, in the process, the gear 11 is disengaged from the second rack 215, and the first rack 214 is driven, at this time, the first rack 214 rotates by taking a first rotation center as an axis to drive the air deflector 30 to perform an upward opening action, and the size of the upward opening of the air deflector 30 can be adjusted by controlling the rotation angle of the gear 11 or the displacement of the gear 11 on the first rack 214; when the air deflector 30 needs to be closed, the gear 11 is rotated in the second direction, the rack connecting plate 20 is driven to return to the initial position through the first rack 214, and at this time, the gear 11 is meshed with the first ends of the first rack 214 and the second rack 215 at the same time; when the air deflector 30 needs to be switched from the upward opening state to the downward opening state, the gear 11 is firstly rotated in the second direction to return the rack connecting plate 20 to the initial position, then the gear 11 is continuously rotated in the second direction to be disengaged from the first rack 214 and start to drive the second rack 215, the second rack 215 rotates around the second rotation center as an axis to drive the air deflector 30 to perform the downward opening action, and the downward opening size of the air deflector 30 can be adjusted by controlling the rotation angle of the gear 11 or the displacement of the gear 11 on the second rack 215.

Similarly, when the air deflector 30 needs to be in a downward opening state, the gear 11 is rotated from an initial state in a second direction, in the process, the gear 11 is disengaged from the first rack 214 and starts to drive the second rack 215, at this time, the second rack 215 rotates around a second rotation center as an axis to drive the air deflector 30 to perform a downward opening action, and the downward opening size of the air deflector 30 can be adjusted by controlling the rotation angle of the gear 11 or the displacement of the gear 11 on the second rack 215; when the air deflector 30 needs to be closed, the gear 11 is rotated in the first direction, the rack connecting plate 20 is driven to return to the initial position by the second rack 215, and at this time, the gear 11 is meshed with the first ends of the first rack 214 and the second rack 215 at the same time; when the air deflector 30 needs to be switched from the downward opening state to the upward opening state, the gear 11 is firstly rotated in the first direction to return the rack connecting plate 20 to the initial position, and then the gear 11 is continuously rotated in the first direction to disengage the gear 11 from the second rack 215 and start to drive the first rack 214, the first rack 214 rotates around the first rotation center as an axis to drive the air deflector 30 to perform the upward opening action, and the size of the upward opening of the air deflector 30 can be adjusted by controlling the rotation angle of the gear 11 or the displacement of the gear 11 on the first rack 214.

Alternatively, when the gear 11 is located on the perpendicular bisector of the connecting line of the arc centers of the first rack 214 and the second rack 215, the air guiding plate 30 is in the closed state, as shown in fig. 1.

It can be understood that, since the position of the gear 11 is not changed, when the gear 11 drives the first rack 214 or the second rack 215 to rotate, the rack connecting plate 20 will move along with the rotation of the rack connecting plate 20, and the arc center connecting line and the perpendicular bisector of the first rack 214 and the second rack 215 will also be in a moving state, and only when the rack connecting plate 20 returns to the initial position, i.e., the gear 11 is engaged with both the first rack 214 and the second rack 215, the air deflector 30 is in a closed state, and when the gear 11 is engaged with only one of the racks, the air deflector will be in an open state, as shown in fig. 1 to 3.

As shown in fig. 9 to 11, optionally, the indoor air conditioner further includes a gear box 13.

The gear box 13 is provided with a motor accommodating cavity 131 and a connecting plate mounting area 132, the gear box 13 is of an open structure and comprises a mounting opening 133 and a rotating opening 134, the mounting opening 133 is used for matching the rack connecting plate 20 with the air deflector support 40, and the rotating opening 134 is used for enabling the rack connecting plate 20 to drive the air deflector 30 to rotate.
