Specifically, a first air duct outlet 11 is arranged on the front side of the air duct shell assembly 10, a first air duct 12 is defined in the air duct shell assembly 10, the first air duct 12 includes an upstream air duct cavity 122 and a downstream air duct cavity 124 arranged above the upstream air duct cavity 122, the downstream air duct cavity 124 is communicated with the first air duct outlet 11, a first fan 126 is arranged in the upstream air duct cavity 122 and used for driving airflow to flow from the upstream air duct cavity 122 to the downstream air duct cavity 124 from bottom to top, and the airflow in the first air duct 12 is driven by the first fan 126 to flow from the upstream air duct cavity 122 to the downstream air duct cavity 124 from bottom to top and then flows out of the air duct component 1 from back to front through the first air duct outlet 11 and blows to the environment where the air duct component 1 is located.

As shown in fig. 1-3, a baffle 30 is rotatably disposed at the outlet of the upstream duct chamber 122, and the baffle 30 is provided with a plurality of spaced apart ventilation apertures 302. The drive assembly is coupled to the baffle 30 to drive the baffle 30 to rotate between the first position and the second position. As shown in fig. 1, in the first position, the air deflector 30 opens the first air duct 12 to make at least a part of the air flow directly flow from the upstream air duct cavity 122 to the downstream air duct cavity 124, so that the scattering effect of the air deflector 30 on the air flow is weakened, and when the air duct shell assembly 10 is applied to the air conditioner 1000, the intensity of the air blown out from the first air duct outlet 11 is higher, and the use requirement of the customer is met. As shown in fig. 2 and fig. 3, in the second position, the baffle 30 blocks between the upstream air duct cavity 122 and the downstream air duct cavity 124 so that the airflow flowing through the outlet of the upstream air duct cavity 122 passes through the baffle 30, and the airflow passing through the baffle 30 is scattered by the baffle 30, so as to reduce the airflow speed, and when the air duct component 1 is applied to the air conditioner 1000, the air blown out from the first air duct outlet 11 can be weakened, thereby improving comfort and meeting the use requirements of customers. Meanwhile, because the guide plate 30 is disposed at the outlet of the upstream air duct cavity 122 and is located in the first air duct 12, the temperature difference between the surface of the guide plate 30 and the air flowing through the surface of the guide plate 30 is extremely low, and condensation is not easily generated.

It is understood that the number and type of wind wheels included in the first wind turbine 126 is not limited, for example, in some specific examples of the present invention, the first wind turbine 126 may include one wind wheel and be a centrifugal wind wheel.

It should be noted that the plurality of spaced apart ventilation pores 302 may be uniformly distributed on the baffle 30 or may be distributed differently according to actual needs. The shape of the ventilation micro-holes 302 may be circular holes, square holes, rectangular holes, elliptical holes, etc., which is not exhaustive.

It should be noted that the downstream air duct chamber 124 refers to a portion of the first air duct 12 opposite to the first air duct outlet 11 in the front-rear direction, and the upstream air duct chamber 122 refers to a portion of the first air duct 12 other than the downstream air duct chamber 124 (i.e., a portion not opposite to the first air duct outlet 11 in the front-rear direction), and the "front-rear direction" referred to herein is shown in fig. 5 and 6.

According to the utility model discloses air duct component 1, exit through the wind channel chamber 122 of upstream sets up rotatable guide plate 30, guide plate 30 opens first wind channel 12 when the first position so that at least partial air current directly flows to downstream wind channel chamber 124 from wind channel chamber 122 of upstream, guide plate 30 can break up the air current of the wind channel chamber 122 exit of upstream of all flowing through when the second position, when air duct component 1 is applicable to in the air conditioner 1000, can make the air conditioner 1000 satisfy the user demand that the customer is different. In addition, because the guide plate 30 is disposed at the outlet of the upstream air duct cavity 122 and is located in the first air duct 12, the temperature difference between the surface of the guide plate 30 and the air flowing through the surface of the guide plate 30 is extremely low, and condensation is not easily generated.

As shown in fig. 1, according to some embodiments of the present invention, in the first position, the baffle 30 engages the inner wall of the upstream air duct cavity 122. Therefore, when the guide plate 30 is at the first position, the air flow passing through the outlet of the upstream air duct cavity 122 can be avoided, the air flow is not scattered, and the use requirements of customers are better met.

According to some embodiments of the present invention, the diameter of the ventilation micropores 302 is D and satisfies: d is more than or equal to 1.5mm and less than or equal to 4mm, so that the diameter size of the ventilation micropores 302 can be reasonably designed, the scattering effect of the guide plate 30 on the air flow flowing through the ventilation micropores is better, and the wind resistance of the guide plate 30 on the air flow flowing through the ventilation micropores is more reasonable. The diameter D of the ventilation micro-holes 302 may be 1.5mm, 2mm, 3mm, 4mm, etc.

According to some embodiments of the present invention, the distance between two adjacent ventilation micropores 302 is L and satisfies: l is more than or equal to 1.5mm and less than or equal to 3 mm. Therefore, the distance between two adjacent ventilation micropores 302 can be designed reasonably, the distribution distance of a plurality of spaced ventilation micropores 302 is designed reasonably, and the airflow flowing through the diversion plate 30 is better dispersed.

According to some embodiments of the present invention, a second air duct 14 communicated with the first air duct outlet 11 is defined in the air duct shell assembly 10, the second air duct 14 is disposed in the downstream air duct cavity 124, and a second fan 142 is disposed in the second air duct 14 to drive the air flow to flow forward from the second air duct 14 and flow out of the air duct component 1 through the first air duct outlet 11. When the air duct component 1 is suitable for the air conditioner 1000, the air outlet capacity of the air conditioner 1000 can be enhanced, and the use experience of a user is improved. By controlling the opening degree of the air deflector 30, that is, by controlling the movement of the air deflector 30 between the first position and the second position, the air volume ratio of the first air duct 12 and the second air duct 14 can be controlled, and when the air duct component 1 is applied to the air conditioner 1000, different air outlet feelings can be formed.

It is understood that the number and types of the wind wheels included in the second fan 142 are not limited, for example, in some specific examples of the present invention, the second fan 142 may include one wind wheel and be an axial flow wind wheel.

As shown in fig. 1, 4, 5 and 6, optionally, the first air duct outlet 11 includes a first air duct opening 112 communicating with the first air duct 12 and a second air duct opening 114 communicating with the second air duct 14, and the first air duct opening 112 surrounds the second air duct opening 114. The air flow from the second air duct 14 can flow out of the air duct component 1 through the second air duct opening 114, and the air flow from the downstream air duct cavity 124 can flow out of the air duct component 1 through the first air duct opening 112 without mutual influence. Because the rotatable baffle 30 is arranged at the outlet of the upstream air duct cavity 122, the airflow flowing through the baffle 30 is broken up, so that the effect of breaking up the airflow flowing out through the first air duct opening 112 and weakening the wind sensation is achieved.

The first air duct 12 is internally provided with a first fan 126, when the first fan 126 comprises a centrifugal wind wheel, the airflow flowing direction of the first air duct 12 is from bottom to top, the airflow of the first air duct 12 flows from the upstream air duct cavity 122 to the downstream air duct cavity 124 from bottom to top, a part of the airflow of the downstream air duct cavity 124 flows forward to the first air duct outlet 11, and because the second air duct outlet 15 is communicated with the first air duct 12, the other part flows upward out of the second air duct outlet 15. While the air flow in the second air duct 14 will only flow to the first air duct outlet 11 and not to the second air duct outlet 15. Therefore, only the first air duct 12 provides air flow to the second air duct outlet 15, and the second air duct 14 does not supply air to the second air duct outlet 15, so that the problems that the second air duct 14 interferes with the air supply of the first air duct 12 to the second air duct outlet 15 and the first air duct 12 interferes with the air supply of the second air duct 14 to the first air duct outlet 11 due to different air flow directions in the first air duct 12 and the second air duct 14 can be avoided.

According to some embodiments of the utility model, the axis of rotation of guide plate 30 extends along left right direction, makes structural design reasonable from this. The air flow flowing through the upstream air duct cavity 122 to the downstream air duct cavity 124 is in an up-down direction or a substantially up-down direction (i.e. a small angle is deviated from the up-down direction, and the specific range of the small angle may be specifically set according to practical requirements, for example, less than 45 °) so that the rotation axis of the air deflector 30 is perpendicular or substantially perpendicular to the air flow direction at the outlet of the upstream air duct cavity 122, thereby making the scattering effect on the air flow better when the air deflector 30 is in the second position.

Here, the "left-right direction" is shown in fig. 1, 2, and 4, and the "up-down direction" is shown in fig. 1 and 2.

According to the utility model discloses a some embodiments, drive assembly locates on the wall outside wind channel shell group 10, makes structural design reasonable from this, reduces drive assembly and hinders the air current mobile possibility in first wind channel 12.

Therefore, the structural design is simplified, and the structural design of the air duct shell assembly 10 is reasonable. The present application is not so limited and in some embodiments the baffle 30 is rotatably disposed on the second housing 104.

As shown in fig. 7, an air conditioner 1000 according to an embodiment of the present invention includes the air duct component 1 described above.
