By adopting the air deflector provided by the embodiment of the disclosure, the first rack 214 for opening the air deflector 30 upwards and the second rack 215 for opening the air deflector 30 downwards are integrated on one rack connecting plate 20, and the gear 10 for driving the air deflector to rotate in the air-conditioning indoor unit can drive the first rack 214 or the second rack 215, so that the air deflector performs the actions of opening upwards, opening downwards or closing the air deflector 30. The present application provides a deflector 30 for cooperation with a simple gear drive apparatus. The air deflector 30 provided by the application can realize two states of upward opening and downward opening by only adopting one set of driving mechanism, and can rotate at a large angle. Alternatively, the number of gears 10 is 1. The air deflector provided by the embodiment of the disclosure requires a small number of movement mechanisms, reduces the probability of movement failure of the air deflector, and improves the reliability of movement of the air deflector 30.
As shown in connection with fig. 1, 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.
It is understood that the rack bar 20 is provided at both ends of the air deflection body 31, thereby facilitating the installation of the air deflection body 31, and the driving structure such as the gear 10 drives the rack bar 20 and the air deflection plate 30.
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.

The rack connecting plate 20 can rotate by the arc center of the first rack 214 and the arc center of the second rack 215, and the arc center of the first rack 214 and the arc center of the second rack 215 are both located at the side of the rack connecting plate 20, so that compared with a structure in which the rotation center is located at the middle, the rack connecting plate 20 and the air deflector 30 connected with the rack connecting plate can rotate at a large angle, and large-area air supply is realized.
Alternatively, the rack portion 21 is in a U-shaped structure with an opening outward, the U-shaped structure includes a bottom portion 213, and a first side portion 211 and a second side portion 212 extending outward along the bottom portion 213, the first rack 214 is disposed on the first side portion 211, and the second rack 215 is disposed on the second side portion 212, as shown in fig. 2.
It is understood that 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, 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 from the second end of the second rack 215. 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.
Optionally, the connecting structure 32 is a socket provided with a slot, the rack connecting plate 20 is provided with a socket portion for accommodating the socket, and a fixture block 222 matched with the slot is provided in the socket portion.
It can be understood that the rack connecting plate 20 is detachably connected with the air deflector body 31, and the rack connecting plate 20 is in snap fit with the air deflector body 31.
In some embodiments, an air conditioning indoor unit includes: the air guiding plate 30.
Optionally, the indoor unit of an air conditioner further includes: gear 10 and motor 50.
The gear 10 is located between the first rack 214 and the second rack 215, and is used for driving the first rack 214 or the second rack 215; the motor 50 is used for driving the gear 10, and 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 body 31 rotates around the second rotation center as the 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 also moves 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 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. 4. 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 guiding plate body 31 to rotate, and the air guiding plate 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 center of rotation does not overlap the second center of rotation.
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 by taking 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.
