[0025] In order to make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved easy to understand, the specific implementation modes of the present invention are further described below in conjunction with specific drawings.

[0026] It should be noted that, for the convenience of description, the drawings only show the parts related to the present invention rather than all structures.

[0027] like Figure 1-3 As shown, in a specific embodiment of the present invention, an air outlet device is provided, including a panel 1 arranged on the indoor unit of the air duct machine, the panel 1 is rectangular, an air outlet 2 is arranged on the panel 1, the air outlet 2 is rectangular, an air outlet frame 5 is arranged on the air outlet 2, the air outlet frame 5 is arranged around the air outlet 2 and located on the inner side of the panel 1, a hook is arranged on the panel 1, and a bayonet matching the hook is arranged at a corresponding position on the air outlet frame 5, and the panel 1 and the air outlet frame 5 are connected by the matching of the hook and the bayonet. Two first air guide plates 3 are arranged on the air outlet 2, and the two first air guide plates 3 are respectively arranged at the two ends of the air outlet 2 (at Figure 1 When the two first air guide plates 3 are closed, the air outlet 2 is just covered. A second air guide plate 4 is also provided between the two first air guide plates 3 in the air outlet 2, and a protrusion 41 is provided on the surfaces of the second air guide plate 4 on opposite sides. The protrusion 41 on the second air guide plate 4 has a certain adsorption effect on the air 20 of the air outlet 2, which will produce a wall attachment effect, thereby changing the wind direction of the air 20 of the air outlet 2, preventing the air 20 of the air outlet 2 from blowing directly to the ceiling or directly to the body of the indoor user, and will not cause discomfort to the user's body. Blowing to the ceiling is easy to cause waste.

[0028] Preferably, the protrusion 41 is arc-shaped.

[0029] Furthermore, the shapes and sizes of the two protrusions 41 on the two opposite surfaces of the second air guide plate 4 are the same or different. The different shapes and sizes of the protrusions 41 will cause different flow directions of the air 20 guided by the second air guide plate 4, thereby meeting the needs of different users.

[0030] like Figure 2 , 3 , 4, and 5, further, the air outlet device of the present invention further includes a linear drive device fixedly connected to both ends of the second air guide plate 4, respectively, for driving the second air guide plate 4 to move linearly, driving one end of the second air guide plate 4 to extend out of or retract into the air outlet 2. By adjusting the distance that the second air guide plate 4 extends out of the air outlet 2, the range of the air outlet 2 can be adjusted. The greater the distance that the second air guide plate 4 extends out of the air outlet 2, the farther the air 20 blows.

[0031] When the second air guide plate 4 extends out of the air outlet 2 to the maximum position, the distance between the outer end of the second air guide plate 4 and the outer surface of the panel 1 is greater than the distance between the outer end of the first air guide plate 3 and the outer surface of the panel 1 (refer to Figure 2 ).

[0032] Furthermore, a rotation driving device is also provided on the linear driving device, and the rotation driving device is fixedly connected to one end of the second air guide plate 4 and drives the second air guide plate 4 to rotate.

[0033] like Figure 4-5 As shown, further, the linear drive device includes a first motor 6 fixed to the outside of the air outlet frame 5, a gear assembly fixedly connected to the output shaft of the first motor 6, and a rack assembly 10 drivingly connected to the gear assembly, and both ends of the second air guide plate 4 are fixedly connected to the rack assembly 10. There are two rack assemblies 10, which are respectively arranged at both ends of the second air guide plate 4, and the rack assembly 10 can be directly fixedly connected to the end of the second air guide plate 4 or indirectly fixedly connected through a connecting member.

[0034] Furthermore, the rotation driving device is a second motor 7, the output shaft of the second motor 7 is fixedly connected to one end of the second air guide plate 4 and drives the second air guide plate 4 to rotate, and the other end of the second air guide plate 4 is rotationally connected to a rack assembly 10. The second motor 7 is fixed to another rack assembly 10. When the first motor 6 drives the rack assembly 10 and the second air guide plate 4 to move linearly at the air outlet 2, the second motor 7 moves together with the rack assembly 10.

[0035] The gear assembly includes a driving gear 12 and a driven gear 13. The driving gear 12 is fixedly connected to the output shaft of the first motor 6, and the driving gear 12 is meshedly connected to the driven gear 13. The driven gear 13 is fixed to the air outlet frame 5 and is rotatably connected.

[0036] Furthermore, a slide groove 11 is respectively disposed on both sides of the air outlet frame 5 , and a rack assembly 10 slidably connected thereto is disposed in each slide groove 11 .

[0037] The rack assembly 10 includes a side plate 101, and a spur rack 102 is provided at the upper and lower ends of one surface of the side plate 101, respectively. The two spur racks 102 are arranged in parallel and their teeth are opposite to each other. A guide rail 103 is provided at the connection between the spur rack 102 and the outer end of the side plate 101. There are two guide rails 103, which are installed in the slide groove 11 and are slidably connected to the slide groove 11. The driving gear 12 and the driven gear 13 are installed between the two spur racks 102 and mesh with one of the spur racks 102 respectively.

[0038] When the first motor 6 rotates, it drives the driving gear 12 to rotate, and the driving gear 12 drives the driven gear 13 to rotate. The driving gear 12 and the driven gear 13 simultaneously drive the two spur racks 102 and the side plate 101 to move linearly in the slide slot 11. By changing the rotation direction of the first motor 6, the moving direction of the rack assembly 10 and the second air guide plate 4 can be changed, thereby controlling the position state of the second air guide plate 4 when it is extended or retracted at the air outlet 2.

[0039] like Figure 1 , 3 4, specifically, one end of one of the first air guide plates 3 located at the upper end of the air outlet 2 is rotatably connected to the air outlet frame 5 through a connecting member, and the other end thereof is fixedly connected to the output shaft of the third motor 8 through a connecting member, and the third motor 8 is fixed to the air outlet frame 5. When the third motor 8 rotates, the first air guide plate 3 is driven to rotate.

When the fourth motor 9 rotates, the first air guide plate 3 is driven to rotate.

[0041] Preferably, the first motor 6 , the second motor 7 , the third motor 8 and the fourth motor 9 are stepping motors.

[0042] like Figure 6 As shown in the figure, it is a schematic diagram of the air outlet device of the present invention in a usage state. When the first air guide plate 3 and the second air guide plate 4 are adjusted to be tilted downward, at this time, the second air guide plate 4 will still have a certain adsorption effect on the air outlet 20 of the air outlet 2, and will produce a wall attachment effect, thereby changing the wind direction of the air outlet 20 of the air outlet 2, avoiding the air outlet 20 of the air outlet 2 from directly blowing to the ceiling or directly blowing to the body of the indoor user, and will not cause discomfort to the user's body, nor will it blow directly to the ceiling, so that the airflow floats on the ceiling and is not easy to come down, causing waste and affecting the air supply effect.

[0043] In addition, the present invention also provides an air duct unit, which includes an outdoor unit and an indoor unit, wherein the indoor unit includes the above-mentioned air outlet device.
