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.

Optionally, the tie rack plate further comprises: the first guiding structure 2211 is engaged with the air deflector bracket 40 and is used for guiding the rotation of the rack connecting plate 20 and the air deflector 30.

As an example, the connecting portion 22 of the rack connecting plate 20 includes a connecting plate body 221 and a connecting member 222, one surface of the connecting plate body 221 is provided with a first guiding structure 2211, the other surface of the connecting plate body 221 is provided with a rack portion 21, the rack portion 21 is a hollow structure, the connecting member 222 is installed in the hollow structure, one side of the rack portion 21 close to the bottom 213 is provided with an opening, the air deflector 30 can pass through the opening to be connected with the connecting member 222, and the rack connecting plate 20 installs the air deflector 30 on the air deflector bracket 40 through the cooperation of the first guiding structure 2211 and the second guiding structure 41.

When the gear 10 drives the first rack 214, the air deflector opens upwards; when the gear drives the second rack, the air deflector is opened downwards.

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, the teeth of the first rack 214 and the second rack 215 are both disposed on the convex surface of the arc-shaped structures, the teeth of the first rack 214 and the second rack 215 are both disposed toward the gear 10, 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.

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 motor 50 is a bidirectional motor 50, 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. 4 to 6.

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. 4.

It can be understood that, since the position of the gear 10 is unchanged, 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, and the connection line between the arc centers of the first rack 214 and the second rack 215 and the perpendicular bisector thereof will also be in a moving state along with the movement of the rack connecting plate 20, and only when the rack connecting plate 20 returns to the initial position, that is, the gear 10 is engaged with both the first rack 214 and the second rack 215, the air deflector 30 is in the closed state, and when the gear 10 is engaged with only one of the racks, the air deflector will be in the open state, as shown in fig. 4 to 6.

Alternatively, a part of the circumferential surface of the gear 10 is provided with teeth.

It can be understood that: the working face of the gear 10 comprises both toothed and toothless portions.

As an example, the arc length of the toothed portion is related to the arc length of the first and second racks 214 and 215, which is less than or equal to the arc length of the first and second racks, optionally the toothed portion of the gear 10 is provided with consecutive teeth; optionally, the area of the non-toothed portion is larger than the area of the toothed portion.

As an example, the toothed portion and the non-toothed portion are respectively located on two sides of the working surface of the gear 10, and in the initial state, the non-toothed portion of the gear 10 faces the gap between the first rack 214 and the second rack 215, as shown in fig. 4, when the gear 10 starts to drive the first rack 214, the toothed portion is engaged with the first rack 214, and the non-toothed portion faces the second rack 215, and the gear 10 is not engaged with the first rack 214 and the second rack 215 at the same time, so as to avoid the seizing.

As an example, the bottom 213 of the U-shaped structure of the rack bar plate is not provided with teeth. A part of the circumferential surface of the gear 10 is provided with teeth, the working surface of the gear 10 comprises a toothed part and a non-toothed part, the toothed part and the non-toothed part are respectively positioned at two sides of the working surface of the gear 10, in an initial state, the non-toothed part of the gear 10 faces the bottom 213, when the gear 10 starts to drive the first rack 214, the toothed part is meshed with the first rack 214, the non-toothed part faces the second rack 215, and the gear 10 is not meshed with the second rack 215; when the gear 10 starts to drive the second rack 215, the toothed part is engaged with the second rack 215, the non-toothed part faces the first rack 214, and the gear 10 is not engaged with the first rack 214; the gear 10 is not meshed with the first rack 214 and the second rack 215 at the same time, so that the rack connecting plate 20 is prevented from being jammed.

As another example, the bottom 213 of the U-shaped structure is provided with teeth for performing a buffering process of rack-fitting switching. The working surface of the gear 10 includes a toothed portion and a non-toothed portion, the toothed portion and the non-toothed portion are respectively located on two sides of the working surface of the gear 10, in an initial state, the non-toothed portion of the gear 10 faces the bottom 213, when the gear 10 starts to drive the first rack 214, the toothed portion is engaged with the first rack 214, the non-toothed portion faces the second rack 215, the gear 10 is not engaged with the second rack 215, and the air deflector 30 is in an upward opening state; when the gear 10 starts to drive the second rack 215, the toothed portion is engaged with the second rack 215, the non-toothed portion faces the first rack 214, the gear 10 is not engaged with the first rack 214, and the air deflector 30 is in a downward opening state.

The gear 10 is not meshed with the first rack 214 and the second rack 215 at the same time, so that the situation that the rack connecting plate 20 is blocked is avoided.

As shown in fig. 2 and 7, optionally, the indoor unit of the air conditioner further includes an air deflector bracket 40 and a second guide structure 41. The second guiding structure 41 is installed on the air deflector bracket 40, and is in sliding fit or rolling fit with the first guiding structure 2211, so as to guide the rotation of the rack connecting plate 20 and the air deflector 30.
