[0031] In the accompanying drawings, the same parts use the same reference numerals. The drawings are not drawn to scale. Detailed Implementation

[0032] The invention will now be further described with reference to the accompanying drawings.

[0033] like Figures 1-6 As shown, the present invention provides an air outlet device, including an air outlet frame 1, an air outlet on the air outlet frame 1, a guide ring 2 installed on the air outlet, a rotating bracket 7 for opening and closing the air outlet inside the guide ring 2, a motor bracket 6 installed on the rotating bracket 7, and a fan assembly installed on the motor bracket 6; a drive assembly is installed on the air outlet frame 1 to drive the rotating bracket 7 to rotate around its own axis, thereby driving the rotating bracket 7 to open and close the air outlet, realizing the opening and closing of the air outlet by the overall rotating fan assembly, effectively preventing dust and other impurities from entering the indoor unit of the air conditioner; at the same time, it realizes the left and right sweeping function of the air outlet device.

[0034] In another embodiment of the present invention, unlike the above embodiments, the air outlet frame 1 in this embodiment is provided with a bearing, and the rotating bracket 7 is connected to the air outlet frame 1 through the bearing. The bearing in this embodiment includes an upper bearing 12 and a lower bearing 13, and the rotating bracket 7 is installed inside the upper bearing 12 and the lower bearing 13. Furthermore, an upper bearing cover 11 is installed on the upper bearing 12, and a lower bearing cover 14 is installed on the lower bearing 13. This allows the rotating bracket to rotate around its own axis, realizing the left and right sweeping function of the air outlet device.

[0035] In another embodiment of the present invention, unlike the above embodiments, the fan assembly in this embodiment includes a fan blade 4 and a fan blade motor 5 for driving the fan blade to rotate, the fan blade motor 5 being mounted on the motor bracket 6. Thus, the air outlet is opened and closed by rotating the frame to drive the entire fan assembly to rotate, making the structure of the entire air outlet device simple and easy to install.

[0036] In another embodiment of the present invention, unlike the above embodiments, the rotating bracket 7 in this embodiment has a hollow spherical structure; and the rotating bracket 7 has a first ventilation port and a second ventilation port that are interconnected, with the motor bracket 6 installed at the first ventilation port. Thus, by driving the rotating bracket 7 through the drive assembly, the left and right sweeping function of the air outlet can be realized.

[0037] In another embodiment of the present invention, unlike the above embodiments, this embodiment also includes a wind-gathering grille 3, which is interference-fitted with the second ventilation opening of the rotating bracket 7. This allows for a longer air transmission distance.

[0038] In another embodiment of the present invention, unlike the above embodiments, the driving component in this embodiment includes a stepper motor 10. The stepper motor 10 is mounted on the upper part of the air outlet frame 1, and a transmission component is installed at its output end. The transmission component includes a driving wheel 9 and a driven wheel 8 that is driven by the driving wheel 9. The driving wheel 9 is connected to the output end of the stepper motor 10. Thus, when the stepper motor 10 rotates clockwise, it drives the driving wheel 9 to rotate in the same direction as the stepper motor 10, both clockwise. The driven wheel 8 rotates counterclockwise, driving the rotating bracket 7 to rotate counterclockwise. At this time, the air outlet changes from a closed state to an open state. Simultaneously, as the rotating bracket 7 rotates, the front air outlet area gradually increases. When the rotating bracket 7 rotates 90 degrees counterclockwise, the air outlet is fully open, at which point the air outlet area is at its maximum. This achieves full opening of the air outlet.

[0039] In another embodiment of the present invention, unlike the embodiments described above, the driven wheel 8 and the rotating bracket 7 are coaxial and rigidly connected. Therefore, there is no situation where the driven wheel rotates first, preventing the rotating bracket from rotating with the driven wheel.

[0040] In another embodiment of the present invention, unlike the above embodiments, the air outlet frame 1 and the air guide ring 2 are integrally connected and formed. This reduces assembly time and improves production efficiency.

[0041] The working principle of this invention is as follows: When the stepper motor 10 rotates clockwise, it drives the driving wheel 9 to rotate in the same direction as the stepper motor 10, which is clockwise. The driven wheel 8 rotates counterclockwise, which drives the rotating bracket 7 to rotate counterclockwise. At this time, the air outlet changes from a closed state to an open state. The front air outlet area will gradually increase as the rotating bracket 7 rotates. When the rotating bracket 7 rotates 90 degrees counterclockwise, the air outlet is fully open, and the air outlet area is at its maximum.

[0042] As the rotating bracket 7 continues to rotate, the area of ​​the air outlet will gradually decrease until it rotates 60 degrees to reach the rotation limit. That is, the rotation angle of the rotating bracket 7 is 150 degrees when the air outlet is opened to the rotation limit. Under the condition of ensuring air outlet, taking the largest air outlet area as the starting point, the maximum angle that the rotating bracket 7 can rotate to the left and right is 60 degrees.

[0043] During the rotation of the aforementioned rotating bracket 7, the opening state of the air outlet is defined as the rotation of the rotating bracket 7 clockwise by 30 degrees from the closed state of the air outlet. This is the left air guide limit. The range of clockwise rotation from 30 degrees to 150 degrees is called the air guide angle. Within this angle range, the stepper motor 10 can be controlled to stop at a certain angle, that is, the air outlet direction can be fixed at a certain angle to achieve directional air guide.

[0044] When in continuous motion, the direction of airflow can be constantly changed to achieve left and right sweeping function.

[0045] like Figure 7 As shown, an indoor air conditioning unit includes an air outlet device 100, an evaporator assembly 200, and a frame 300 as described above. The air outlet device 100 and the evaporator assembly 200 are both mounted on the frame 300. The air inlet of the air outlet device is connected to the air outlet of the evaporator assembly, thereby delivering cold or hot air to the room to cool or heat the indoor environment.

[0046] An air conditioner includes an outdoor unit and an indoor unit as described above, wherein the outdoor unit is connected to the indoor unit via a refrigerant pipe, thereby enabling the air conditioner to perform cooling or heating functions.

[0047] In the description of this invention, it should be understood that the terms "upper", "lower", "bottom", "top", "front", "rear", "inner", "outer", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0048] Although the invention has been described with reference to preferred embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention.
