The initial position of the gear 10 is located at the bottom 213 of the U-shaped structure, when the gear 10 drives the first rack 214, the rack connecting plate 20 rotates around the arc center of the first rack 214 and drives the air deflector body 31 to rotate, so that the air deflector 30 is in an upward opening state, and when the gear 10 drives the second rack 215, the rack connecting plate 20 rotates around the arc center of the second rack 215 and drives the air deflector body 31 to rotate, so that the air deflector 30 is in a downward opening state.

As an example, the entire circumference of the gear 10 is provided with teeth, and the bottom 213 of the rack connecting plate 20 is not provided with teeth, so that the gear 10 and the rack portion 21 are prevented from being stuck to affect normal rotation fit.

As shown in connection with fig. 2, the rack attachment plate 20 optionally includes a first rack attachment plate and a second rack attachment plate.

The first rack connecting plate is disposed at a first end of the inner side wall of the air deflector body 31, and the second rack connecting plate is disposed at a second end of the inner side wall of the air deflector body 31.

Optionally, the air deflector 30 further comprises: the air guide plate support member 33 is disposed on an inner sidewall of the air guide plate body 31. The air deflector support 33 is used for supporting the air deflector 30 and preventing the air deflector 30 from being bent due to too concentrated stress.

Optionally, the air deflection support 33 is disposed between the first rack connecting plate and the second rack connecting plate. Thus, the air deflector body 31 can be driven to rotate from both ends of the air deflector body 31, and the air deflector 30 can be supported at the middle of the air deflector body 31.

Optionally, the indoor unit of an air conditioner further includes: a gear for driving the first rack or the second rack; and, a motor for driving the gear; when the gear drives the first rack, the air deflector body rotates by taking the first rotation center as an axis, so that the air deflector body is in an upward opening state; when the gear drives the second rack, the air deflector body rotates by taking the second rotation center as an axis, so that the air deflector body is in a downward opening state.

Optionally, the drive assembly further comprises: a motor 50 for driving the gear 10.

The gear 10 is located between the first rack 214 and the second rack 215, and drives the first rack 214 or the second rack 215.

When the gear 10 drives the first rack 214, the air deflector body 31 rotates around the first rotation center as an axis, so that the air deflector 30 is in an upward opening state; when the gear 10 drives the second rack 215, the air deflector 30 rotates around the second rotation center as an axis, so that the air deflector body 31 is in a downward opening state.

It is understood that the gear 10 may be meshed with the first rack 214, or meshed with the second rack 215, so as to drive the first rack 214 or the second rack 215 to rotate, and when the gear 10 drives the first rack 214 to rotate, the gear 10 is not meshed with the second rack 215; when the gear 10 drives the second rack 215 to rotate, the gear 10 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 10, 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 pinion 10 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. 7. At this time, the air deflector is in a closed state. When the first rack 214 or the second rack 215 needs to be driven by the gear 10, the gear 10 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 10 is rotated in the direction opposite to the initial driving direction.

As another example, when the gear 10 drives the first rack 214, the first rack 214 rotates around its own arc center, i.e. the first rotation center, and drives the air deflector body 31 to rotate, and the air deflector 30 is in an upward opening state; when the gear 10 drives the second rack 215, the second rack 215 rotates around the arc center thereof, i.e. the second rotation center, and drives the air guiding plate body 31 to rotate, and the air guiding plate 30 is in a downward opening state. The first rotation center and the second rotation center may be understood as virtual axes. The first rotation center and the second rotation center do not overlap.

The motor 50 is a bidirectional motor, and can drive the gear 10 to rotate in both forward and reverse directions.

The movement principle of the embodiment of the present disclosure will be described below with reference to fig. 5 to 7.

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 centers of the first and second racks 214 and 215, respectively, and the pinion 10 is located at the first ends of the first and second racks 214 and 215 in the initial state.

Taking the gear 10 as an example of full teeth, in practice, the gear 10 is engaged with the first rack 214 and the second rack 215 simultaneously in the initial state. When the air deflector 30 is required to be in an upward opening state, the gear 10 is rotated in a first direction from an initial state, in the process, the gear 10 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 10 or the displacement of the gear 10 on the first rack 214; when the air deflector 30 needs to be closed, the gear 10 is rotated in the second direction, the rack connecting plate 20 is driven to return to the initial position by the first rack 214, and at this time, the gear 10 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 10 is firstly rotated in the second direction to return the rack connecting plate 20 to the initial position, and then the gear 10 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 10 or the displacement of the gear 10 on the second rack 215.

Similarly, when the air deflector 30 is required to be in a downward opening state, the gear 10 is rotated from an initial state in a second direction, in the process, the gear 10 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 10 or the displacement of the gear 10 on the second rack 215; when the air deflector 30 needs to be closed, the gear 10 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 10 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 10 is firstly rotated in the first direction to return the rack connecting plate 20 to the initial position, then the gear 10 is continuously rotated in the first direction to be disengaged from the second rack 215, and the first rack 214 is started to be driven, 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 10 or the displacement of the gear 10 on the first rack 214.

Alternatively, when the gear 10 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 deflector 30 is in the closed state, as shown in fig. 7.

It can be understood that, since the position of the gear 10 is not changed, when the gear 10 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 10 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 10 is engaged with only one of the racks, the air deflector will be in an open state, as shown in fig. 5 to 7.

As shown in fig. 3 and 8, optionally, the indoor unit of an air conditioner further includes: a first guide structure 231 and a second guide structure 41.

It can be understood that, when being installed, the installation opening 63 of the gear box 60 is disposed toward the air deflector support 40, the gear box 60 is fixed on the air deflector support 40 through a connecting piece, wherein the motor 50 is installed in the motor accommodating cavity 61, the motor 50 is connected with the gear 10, the gear 10 is engaged with the first rack 214 or the second rack 215 on the rack connecting plate 20, the rack connecting plate 20 is rotatably installed on the connecting plate installation area 62, and the rack connecting plate 20 is installed on the air deflector support 40 through the first guiding structure 231, so as to ensure stable connection between the gear 10 and the rack connecting plate 20.

The present application integrates a first rack 214 for upward opening and a second rack 215 for downward opening on the rack attachment plate 20, and the air deflector 30 can perform upward opening and downward opening actions through the rack attachment plate 20. By adopting the air deflector 30 provided by the application, two states of upward opening and downward opening can be realized by adopting one set of driving assembly, the large-angle rotation of the air deflector body 31 is realized, the movement mechanism is effectively simplified, the development cost and the equipment failure probability are reduced, and the movement reliability of the air deflector 30 is improved.

When equipment is in failure and the air deflector 30 needs to be disassembled for maintenance, the air deflector 30 can be disconnected from the rack connecting plate 20 by removing the connection relation between the first connecting part 32 and the second connecting part 22, because the rack connecting plate 20 is installed on the air deflector bracket 40, when the air deflector 30 is disconnected from the rack connecting plate 20, the air deflector 30 finishes the disassembling action, and when the air deflector 30 needs to be installed, the connection relation between the first connecting part 32 and the second connecting part 22 can be restored.

By adopting the scheme, the driving structure of the air deflector 30 can be simplified, and the air deflector 30 can be conveniently disassembled and assembled.
