[0046] Figure 1 This is a schematic structural diagram of a wind equalization component according to an embodiment of the present invention, such as... Figure 1 As shown, and with reference Figures 2 to 7This invention provides an airflow equalization assembly, including an airflow channel extending along a preset direction and an airflow outlet 130 extending along the preset direction. The assembly also includes a first equalization half-column 100 and a second equalization half-column 200 symmetrically arranged. The first equalization half-column 100 has a first opening edge 110 extending along the preset direction for defining the airflow outlet 130, and the inner wall surface of the first equalization half-column 100 is a portion of the wall surface of the airflow channel. The second equalization half-column 200 has a second opening edge 210 extending along the preset direction for defining the airflow outlet 130, and the inner wall surface of the second equalization half-column 200 is a portion of the wall surface of the airflow channel. Both the first equalization half-column 100 and the second equalization half-column are rotatably arranged about the preset direction, so that the first opening edge 110 and the second opening edge 210 move closer to or further away from each other.

[0047] In the air-uniformity assembly provided in this embodiment of the invention, the inner walls of the first air-uniformity semi-column 100 and the second air-uniformity semi-column 200 form portions of the airflow channel wall, and the first opening edge 110 and the second opening edge 210 form portions of the airflow outlet 130. In application, both the first air-uniformity semi-column 100 and the second air-uniformity semi-column are rotatably arranged around a preset direction, causing the first opening edge 110 and the second opening edge 210 to move closer to or further away from each other, thereby opening and closing the airflow outlet 130 and adjusting its area. When the air conditioner is not in use, the airflow outlet 130 is closed to prevent foreign objects from falling in.

[0048] In some embodiments of the present invention, such as Figure 2 , Figure 3 As shown, the air distribution assembly also includes a base 300. A first air distribution semi-column 100 and a second air distribution semi-column 200 are rotatably mounted on the base 300, with the rotation axes of the first air distribution semi-column 100 and the second air distribution semi-column 200 either coincidentally or spaced apart. The base 300, the first air distribution semi-column 100, and the second air distribution semi-column 200 define an airflow channel. Further, the inner wall of the base 300 has two symmetrically arranged arc-shaped sealing sections, which are coaxial with the rotation axes of the first air distribution semi-column 100 and the second air distribution semi-column 200, respectively. The first air distribution semi-column 100 has a first arc-shaped section coaxial with its rotation axis, which contacts one arc-shaped sealing section. The second air distribution semi-column 200 has a second arc-shaped section coaxial with its rotation axis, which contacts the other arc-shaped sealing section.

[0049] In the wind-uniform component provided in this embodiment of the invention, the two arc-shaped sealing sections of the base 300 respectively contact the first arc-shaped section of the first wind-uniform half-column 100 and the second arc-shaped section of the second wind-uniform half-column 200 to seal the gaps in the rotation process of the first wind-uniform half-column 100 and the second wind-uniform half-column 200, prevent air leakage in the airflow channel, make the wind-uniform component tightly sealed, and be able to stably deliver fresh air to the target space.

[0050] Specifically, such as Figure 2 As shown, the first uniform airflow semi-column 100 has two first end plates 120, and the second uniform airflow semi-column 200 has two second end plates 220. Each first end plate 120 and a second end plate 220 are arranged to overlap. When the first opening edge 110 and the second opening edge 210 approach each other, the first end plates 120 and the second end plates 220 can overlap in a staggered manner to avoid interfering with the rotation of the first uniform airflow semi-column 100 and the second uniform airflow semi-column 200, and also to prevent gaps from forming between the first uniform airflow semi-column 100 and the second uniform airflow semi-column 200 during rotation, thus preventing air leakage in the airflow channel.

[0051] In some alternative embodiments of the present invention, the first end plate 120 is a hollow structure, and the second end plate 220 is inserted into the first end plate 120. When the first opening edge 110 and the second opening edge 210 approach each other, the second end plate 220 is inserted into the hollow first end plate 120 to prevent air leakage in the airflow channel, so that the air distribution assembly is tightly sealed and can stably deliver fresh air to the target space.

[0052] In some alternative embodiments of the present invention, the second end plate 220 is a hollow structure, and the first end plate 120 is inserted into the second end plate 220. When the first opening edge 110 and the second opening edge 210 approach each other, the first end plate 120 is inserted into the hollow second end plate 220 to prevent air leakage in the airflow channel, so that the air distribution assembly is tightly sealed and can stably deliver fresh air to the target space.

[0053] In some embodiments of the present invention, the air-uniforming assembly further includes a plurality of air-uniforming fins. The air-uniforming fins are spaced apart within the airflow channel along a predetermined direction. Each air-uniforming fin includes a first air-uniforming half-fin and a second air-uniforming half-fin. The first air-uniforming half-fin is mounted on a first air-uniforming half-column, and the second air-uniforming half-fin is mounted on a second air-uniforming half-column. Each first air-uniforming half-fin and a second air-uniforming half-fin are arranged in an overlapping manner so that when the first opening edge and the second opening edge approach each other, they can overlap in a staggered manner. In application, after the airflow enters the airflow channel, the air-uniforming fins guide and divert the airflow, making it easier for the airflow to flow to the airflow outlet 130, improving the uniformity of the airflow and the uniformity of the mixed airflow. In particular, when the first opening edge 110 and the second opening edge 210 approach each other, the first air-uniforming half-fin and the second air-uniforming half-fin can overlap in a staggered manner to avoid interfering with the rotation of the first air-uniforming half-column 100 and the second air-uniforming half-column 200.

[0054] In some embodiments of the present invention, such as Figures 3 to 5 As shown, the air distribution assembly also includes a first gear 410 and a second gear 420. The first gear 410 is mounted at one end of the first air distribution semi-column 100, and a first rotating column 430 is mounted at the other end of the first air distribution semi-column 100. The first gear 410, the first rotating column 430, and the rotation axis of the first air distribution semi-column 100 are coaxial. The second gear 420 is mounted at one end of the second air distribution semi-column 200, and a second rotating column 440 is mounted at the other end of the second air distribution semi-column 200. The second gear 420, the second rotating column 440, and the rotation axis of the second air distribution semi-column 200 are coaxial. Both the first rotating column 430 and the second rotating column 440 are mounted on the base to support the first air distribution semi-column 100 and the second air distribution semi-column 200. The first gear 410 meshes with the second gear 420.

[0055] Furthermore, the air distribution assembly also includes a motor 500, the output end of which is connected to the first gear 410 to drive the first gear 410 to rotate. In application, the motor 500 drives the first air distribution half-column 100 to rotate through the first gear 410, while the second gear 420, which meshes with the first gear 410, drives the second air distribution half-column 200, thereby causing the first opening edge 110 and the second opening edge 210 to move closer or further apart, so as to realize the opening and closing of the airflow outlet 130 and the adjustment of the area of ​​the airflow outlet 130.

[0056] This invention also provides an air conditioner, including an indoor unit, which includes an air distribution component as described in any of the above embodiments, to have all the effects of the air distribution component.

[0057] In some embodiments of the present invention, such as Figure 6 and Figure 7 As shown, the indoor unit also includes a heat exchange section 600, which has a heat exchange air outlet 610. The length direction of the heat exchange air outlet 610 is parallel to the extension direction of the airflow channel. An airflow outlet 130 is disposed on one side of the heat exchange air outlet 610 to facilitate the mixing of airflow from the airflow outlet 130 and airflow from the heat exchange air outlet 610, so that the airflow is mixed more evenly.

[0058] In some embodiments of the present invention, the air conditioner further includes a fresh air device, wherein the air distribution assembly has an airflow inlet communicating with an airflow channel, and the air outlet of the fresh air device is communicating with the airflow inlet. The fresh air device may include a fresh air fan and a fresh air duct. The outlet of the fresh air fan is the air outlet of the fresh air device, and the fresh air duct connects the outside of the target space and the inlet of the fresh air fan.

[0059] In some preferred embodiments of the present invention, the heat exchange section 600 is provided with a through channel extending through it in a front-rear direction. Two heat exchange air outlets 610 are provided on both sides of the front end of the through channel; an air distribution assembly is disposed within the through channel, with the airflow outlet 130 facing forward. The air distribution assembly is spaced apart from the channel wall of the through channel to allow airflow from the rear side of the heat exchange section 600 to flow through the through channel to the front side of the heat exchange section 600.

[0060] This invention also provides an air outlet control method for an air conditioner, which is applied to an air conditioner as described in any of the above embodiments. The air outlet control method for the air conditioner includes:

[0061] S1: Detects the air quality within the target space;

[0062] S2: If the air quality is lower than the first preset air quality value, the first inlet edge 110 and the second inlet edge 210 are brought closer to each other so that the airflow outlet 130 is reduced.

[0063] S3: When the air quality in the target space increases to a second preset air quality value, the first inlet edge 110 and the second inlet edge 210 are moved away from each other to enlarge the airflow outlet 130. The second preset air quality value is greater than the first preset air quality value, or the second preset air quality value is equal to the first preset air quality value.

[0064] Specifically, when the air quality in the target space is detected to be lower than the second preset air quality value, the first inlet edge 110 and the second inlet edge 210 are controlled to move closer to each other, so that the air outlet 130 is reduced in size, the flow rate of the fresh air flowing out of the air outlet 130 increases, the air delivery distance becomes longer, and the fresh air will blow to a farther place, which facilitates the rapid mixing of fresh air and air in the target space and improves air quality.

[0065] When the air quality in the target space is detected to reach the second preset air quality value, the first outlet edge 110 and the second outlet edge 210 are controlled to move away from each other, thereby expanding the airflow outlet 130. The flow rate of the fresh air flowing out of the airflow outlet 130 is reduced, and the fresh air delivery distance is short, so that the fresh air is fully mixed with the air in the target space, avoiding a large temperature difference when it blows onto the human body, and ensuring comfort.

[0066] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Thus, the scope of the present invention should be understood and construed as covering all such other variations or modifications.
