[0051] The air guide assembly is provided with a first air outlet channel 3 extending along the path A, the first air outlet channel 3 is connected with the upper air duct 1.11, and discharges air in a first direction;

[0052] The air guide assembly is further provided with a second air outlet channel 4 extending along the path B, the second air outlet channel 4 is connected with the lower air channel 1.12, and discharges air along a second direction, and the second direction is arranged to intersect with the first direction;

[0053] The first air outlet channel 3 and the second air outlet channel 4 are respectively provided with left and right air guide blade groups 5;

[0054] An assembly space is provided inside the partition 2, and an actuator 11 is provided in the assembly space. The output end of the actuator 11 is respectively connected to the left and right air guide blade groups 5 of the first air outlet channel 3 and the left and right air guide blade groups 5 in the second air outlet channel 4 through a transmission component. The actuator 11 drives the left and right air guide blade groups 5 to swing left and right through the transmission component to control the left and right air outlet angles.

[0055] The air duct 1.1 is divided into an upper air duct 1.11 and a lower air duct 1.12 by a partition 2, and a guide assembly is provided at the rear end of the air outlet housing 1, and the guide assembly is provided with a first air outlet channel 3 extending along a path A and communicating with the upper air duct 1.11, and a second air outlet channel 4 extending along a path B and communicating with the lower air duct 1.12;

[0056] The first air outlet channel 3 discharges air along a first direction, and the second air outlet channel 4 discharges air along a second air outlet direction, and the second direction intersects with the first direction.

[0057] Since the first air outlet channel 3 extends along the path A, the airflow is directed in a horizontal direction (first direction), and since the second air outlet channel 4 extends along the path B, the airflow is directed in an upward direction (second direction), and the two airflows converge to realize an upward inclined airflow.

[0058] Compared with existing similar products, there is no need to set up air volume blades to control the air volume entering the first air outlet channel 3 and the second air outlet channel 4 to obtain the required air outlet direction, and there is no need to set up a driving mechanism (actuator 11, transmission mechanism, etc.) to drive the air volume blades. It has the characteristics of reducing parts and components, reducing costs, occupying less space, better aesthetics, and long service life.

[0059] In addition, left and right air guide blade groups 5 are respectively provided in the first air outlet channel 3 and the second air outlet channel 4, and the left and right air guide blade groups 5 can adjust the airflow in the left and right directions;

[0060] The actuator 11 driving the two left and right air guide blade groups 5 is arranged in the partition 2, and the actuator 11 and the transmission assembly are hidden in the air outlet housing 1, so that the space utilization rate is high and the overall design is better.

[0061] See also Figure 1-5 As shown, the air outlet housing 1 is an integrally formed thin-walled structure, and an air duct 1.1 is formed inside;

[0062] A U-shaped groove 1.13 is provided inside the air duct 1.1, the bottom of the U-shaped groove 1.13 extends toward the front end of the air duct 1.1, and the groove opening is located at the rear end of the air duct 1.1;

[0063] The separator 2 is a U-shaped thin-walled structure, and the separator 2 is adapted to be assembled in the U-shaped groove 1.13.

[0064] The air outlet housing 1 with an integrally formed thin-wall structure has an overall light weight and good structural strength, thereby avoiding structural weaknesses that may be caused by assembling multiple parts, reducing assembly steps, improving production efficiency, and reducing production costs.

[0065] The matching design of the separator 2 and the U-shaped groove 1.13 makes installation easier and reduces the error and complexity during the installation process.

[0066] After the partition 2 is installed in the U-shaped groove 1.13, an upper air duct 1.11 and a lower air duct 1.12 separated from each other can be formed. Compared with the existing double-channel air outlet, the structure is simpler and easier to produce and process.

[0067] The front surface of the partition 2 is designed with a smooth transition, which can efficiently introduce the airflow into the corresponding upper air duct 1.11 and lower air duct 1.12, reduce resistance and noise, and enhance the user experience.

[0068] See also Figure 1-5 As shown, the flow guide assembly includes a first channel 6, a partition 7, and a decorative part 8;

[0073] The first channel 6, the partition 7, and the decorative part 8 are respectively thin-walled structures. After molding is completed, the corresponding guide surfaces can be formed. The surfaces of the molded parts are used as guide surfaces to guide the airflow. There is no need to use additional guide components (such as blades, etc.). There are fewer structural components, which reduces costs.

[0074] The flow guide assembly also includes a second channel 9 and a lower connecting plate 10;

[0075] The second channel 9 extends into the tail end of the lower air duct 1.12, and the lower connecting plate 10 is connected to the lower side of the partition 7;

[0076] The upper wall surface of the second channel 9 and the lower wall surface of the decorative component 8 are connected to form a second flow guide surface b;

[0077] The lower wall surface of the second channel 9 and the upper wall surface of the lower connecting plate 10 are connected to form a second guide surface bb;

[0078] The second guide surface b and the second guide surface bb extend along the path B, and a second air outlet channel 4 is formed therebetween.

[0079] After the second channel 9 and the lower connecting plate 10 are formed, the corresponding guide surfaces can be formed.

[0080] Among them, the first channel 6 and the second channel 9 are respectively connected to the rear end of the air outlet shell 1 through a snap-fit ​​structure, and the partition 7 is also connected to the first channel 6, the rear end of the second channel 9, and the rear end of the air outlet shell 1 through a snap-fit ​​structure. The overall splicing structure setting facilitates assembly.

[0081] A baffle 7.1 is arranged at the position of the partition 7 corresponding to the tail of the partition 2. The baffle 7.1 is connected to the tail of the partition 2 and is used to cover the tail opening of the partition 2; the actuator 11 and the transmission assembly are placed in a relatively closed space, reducing external contact and extending the service life.

[0082] The trim 8 is detachably connected to the rear end of the baffle 7.1.

[0083] The tail of the baffle 7.1 is formed with a flange protruding toward the tail, and the inner side of the decorative part 8 has a snap-in structure that can be snapped onto the flange. A light-emitting component can also be provided on the inner side of the decorative part 8, which further facilitates assembly and enhances the user experience.

[0084] See also Figure 1-5 As shown, the left and right air guide blade groups 5 of the first air outlet channel 3 are arranged in the first channel 6;

[0085] The left and right air guide blade groups 5 of the second air outlet channel 4 are arranged in the second channel 9;

[0089] The output end of the actuator 11 is provided with a driving gear 11.1, and the driving gear 11.1 is meshed with the driven gear.

[0090] The vertical blades 5.1 in the first air outlet channel 3 and the vertical blades 5.1 in the second air outlet channel 4 are symmetrically arranged. When the rotating shaft 12 rotates, it drives the two groups of vertical blades 5.1 to swing in parallel with the same swing angle, so that the flow performance after the airflow converges is better.

[0091] In addition, the actuator 11 is fixed in the assembly space by a threaded connector, the rotation axis of each group of vertical blades 5.1 extends to the outside of the air outlet housing 1 respectively, and the rotation axes are linked by connecting rods, so the structural layout is more compact.

[0092] Compared with the existing blade drive mechanism, the transmission assembly also has the characteristics of fewer parts, lower cost, and easier assembly.
