[0037] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] like Figures 1 to 12 As shown, an embodiment of the present invention provides an air outlet device, including: a shell structure, the shell structure has an air outlet area and a protection area 11, and the air outlet area has multiple air outlets 12; a damper 20, the damper 20 is movably arranged on the shell structure to adjust the opening size of the air outlet 12, and the damper 20 has an open position in the protection area 11 and a closed position in the air outlet area; when the damper 20 is in the open position, the air outlet 12 is fully opened, and when the damper 20 is in the closed position, the air outlet 12 is closed; there are multiple dampers 20, and the multiple dampers 20 and the multiple air outlets 12 are arranged one by one; a driving mechanism 30, and the driving mechanism 30 is connected to the damper 20 to drive the damper 20 to move.

[0039] In this solution, multiple dampers 20 are movably arranged, so that the air outlet 12 can be opened, closed or partially opened to adjust the air volume as needed. Moreover, the damper 20 is in the protection area 11 when the air outlet 12 is opened, that is, the damper 20 is completely away from the air outlet 12, so the damper 20 will not block the air outlet, thereby increasing the air outlet area. When the air conditioner stops running, the damper 20 can close the air outlet 12 to ensure safety. Moreover, in this solution, the air outlet 12 is set to be multiple, rather than being set to only one larger air outlet, which can avoid safety hazards such as easy entry of foreign objects due to the air outlet 12 being too large. Specifically, the air outlet device is applied to the outdoor unit of the air conditioner.

[0040] In this embodiment, the air outlet area has a center line, and the plurality of air outlets 12 and the plurality of dampers 20 are arranged around the center line. The protection area 11 is an annular area, and the protection area 11 is arranged around the air outlet area. After the plurality of air outlets 12 are opened, the air outlet area of ​​the air outlet area is relatively large, which ensures the air outlet effect, improves the performance of the air conditioner and reduces the noise.

[0041] Specifically, the shell structure includes: a mask 40, the mask 40 has an avoidance hole 41, and the protection area 11 is located on the mask 40; an air outlet grille 50, which is located at the avoidance hole 41. The air outlet grille 50 includes a support ring 51, a connecting piece 52 and a plurality of ribs 53. The connecting piece 52 is located in the middle of the support ring 51, and the two ends of each rib 53 are respectively connected to the support ring 51 and the connecting piece 52. The plurality of ribs 53 divide the area between the support ring 51 and the connecting piece 52 into a plurality of air outlets 12. The plurality of ribs 53 on the air outlet grille 50 can divide a plurality of air outlets 12 in the air outlet area, and the ribs 53 can play a protective and structural support role, thereby increasing the structural strength. Moreover, compared with the existing conventional air outlet grille, the air outlet grille 50 in this scheme has a greatly reduced number of ribs, which reduces the air flow resistance, thereby increasing the air volume. When the air outlet is not needed, the air outlet 12 can be closed by the damper 20 to ensure safety, and can play a dustproof, insect-proof and waterproof effect.

[0042] like Figure 5 and Figure 6 As shown, the damper 20 is rotatably arranged on the shell structure, and the circumference of the air outlet 12 has three first arc-shaped edges arranged in sequence, and the circumference of the damper 20 has three second arc-shaped edges arranged in sequence, and the curvature of the first arc-shaped edge and the second arc-shaped edge are the same. Through the above arrangement, when the damper 20 is in the closed position, the outer periphery of the damper 20 can be well matched with the inner periphery of the air outlet 12, so that no gap will appear, and the air outlet 12 is completely closed, thereby improving the protection effect. Moreover, after the damper 20 is opened, it can completely avoid the air outlet 12 and will not hinder the flow of gas. Specifically, the ribs 53 are arc-shaped ribs.

[0043] Furthermore, the housing structure has a first stopper 13, and the first stopper 13 cooperates with the damper 20 to limit the rotation range of the damper 20. In this way, the movement range of the damper 20 is limited, the damper 20 is prevented from moving to an inappropriate position, and the displacement accuracy of the damper 20 is ensured.

[0044] Specifically, the damper 20 has an arc-shaped guide groove 21, and the first position-limiting member 13 is a columnar structure, and the first position-limiting member 13 passes through the arc-shaped guide groove 21. Through the cooperation of the arc-shaped guide groove 21 and the first position-limiting member 13, on the one hand, the damper 20 can be guided to make the rotation of the damper 20 more stable, and on the other hand, the inner walls at both ends of the arc-shaped guide groove 21 cooperate with the first position-limiting member 13 to limit the movement range of the damper 20. Specifically, when the inner wall at one end of the arc-shaped guide groove 21 abuts against the first position-limiting member 13, the damper 20 moves to the open position, and when the inner wall at the other end of the arc-shaped guide groove 21 abuts against the first position-limiting member 13, the damper 20 moves to the closed position, so that the damper 20 can be controlled to move accurately to the open position or the closed position.

[0045] like Figure 5 As shown, the damper 20 includes a rotating wheel 22 and a moving piece 23 connected to each other, the rotating wheel 22 is rotatably arranged on the housing structure, and the shape of the moving piece 23 matches the air outlet 12, wherein the rotating wheel 22 and the moving piece 23 are an integral structure, or the rotating wheel 22 and the moving piece 23 are a separate structure. The rotating wheel 22 drives the moving piece 23 to move, so that the moving piece 23 opens or closes the air outlet 12.

[0046] Specifically, the wheel 22 includes a plurality of external teeth, the driving mechanism 30 includes a ring gear 31, the ring gear 31 is arranged around the air outlet area, the ring gear 31 is rotatably arranged on the housing structure, and the ring gear 31 and the wheels 22 of the plurality of dampers 20 are all meshed to drive the plurality of dampers 20 to rotate synchronously. With this solution, the plurality of dampers 20 can be driven to rotate synchronously by the ring gear 31, thus simplifying the structure of the device and ensuring the movement synchronization of the plurality of dampers 20.

[0047] like Figure 2 and Figure 3 As shown, the inner side of the ring gear 31 has a plurality of inner teeth, the outer side of the ring gear 31 has a plurality of outer teeth, and the inner teeth of the ring gear 31 mesh with the outer teeth of the rotating wheel 22; the driving mechanism 30 also includes a motor 32 and a driving gear 33, the motor 32 is arranged on the housing structure, the output shaft of the motor 32 is connected to the driving gear 33, and the driving gear 33 meshes with the outer teeth of the ring gear 31. This arrangement has a compact structure and reliable transmission.

[0048] In this embodiment, the housing structure includes a mask 40, an air outlet grille 50 and an annular support frame 60, the air outlet grille 50 is connected to the mask 40, the air outlet grille 50 has a plurality of air outlets 12, the support frame 60 is connected to the mask 40 or the air outlet grille 50, and the ring gear 31 is sandwiched between the mask 40 and the support frame 60. In this way, the ring gear 31 is installed and limited by the support frame 60 and the mask 40. Among them, the first limiter 13 can be set on the support frame 60.

[0049] Furthermore, the housing structure further includes a plurality of second stoppers 14, which are disposed on the mask 40 and / or the support frame 60, and are disposed around the ring gear 31 to limit the radial direction of the ring gear 31. In this way, the plurality of second stoppers 14 limit the radial position of the ring gear 31, so that the ring gear 31 can only rotate in the circumferential direction. Figure 2 As shown, a plurality of second stoppers 14 are provided on the mask 40. Fig.12 As shown, a plurality of second limiting members 14 are disposed on the supporting frame 60 .

[0050] like Figure 4As shown, in this embodiment, the mask 40 has an avoidance hole 41, and the air outlet grille 50 includes a support ring 51, and the support ring 51 includes an inner ring 54 and an outer ring 55 arranged in a step-like manner, wherein the inner ring 54 penetrates into the avoidance hole 41, and the outer ring 55 is connected to the mask 40 through a fastener. Through the above arrangement, the accurate positioning of the mask 40 and the air outlet grille 50 is facilitated, and the assembly accuracy and efficiency are improved.

[0051] Furthermore, the air outlet grille 50 includes a support ring 51 and a plurality of connecting shafts 56 disposed on the support ring 51, the plurality of connecting shafts 56 correspondingly pass through the plurality of rotating wheels 22, and the support frame 60 is connected to the connecting shafts 56 via fasteners. Through the above arrangement, the limiting and supporting of the rotating wheels 22 are realized, and the connection between the supporting frame 60 and the air outlet grille 50 is realized. Such a structure achieves two purposes, thereby simplifying the structure of the air outlet device, reducing the number of parts, and improving assembly efficiency.

[0052] like Fig.11 As shown, the housing structure further includes a plurality of third stoppers 15, which are distributed on the mask 40, and are arranged one by one with the plurality of moving pieces 23. The third stoppers 15 have a stopper groove, and one end of the moving piece 23 away from the rotating wheel 22 is inserted into the corresponding stopper groove. In this way, the third stoppers 15 can guide and stop the moving piece 23. Especially for a moving piece 23 with a relatively large size, the stability of the moving piece 23 during movement can be improved.

[0053] In the present application, the driving mechanism 30 includes a motor 32, and the motor 32 drives the multiple dampers 20 to move synchronously. Alternatively, the driving mechanism 30 includes multiple motors 32, and the multiple motors 32 drive the multiple dampers 20 to move in a one-to-one correspondence. The specific selection can be made according to needs.

[0054] like Figure 6 As shown, the air outlet device further includes a detection module 70, which is arranged on the housing structure. The detection module 70 is used to detect whether there is a foreign object close to the air outlet 12 within a preset range; when the detection module 70 detects that there is a foreign object close to the air outlet 12, the driving mechanism 30 drives the damper 20 to move to the closed position. Through the above arrangement, foreign objects can be prevented from entering the air conditioner, thereby improving the safety of the device and personnel. Specifically, the detection module 70 is an infrared detection module, which is arranged in the middle of the air outlet grille 50.

[0055] Another embodiment of the present invention provides an air conditioner outdoor unit, which includes the above-mentioned air outlet device. In this solution, multiple dampers 20 are movably arranged, so that the air outlet 12 can be opened, closed or opened as part of the air outlet 12 to adjust the air volume as needed, and the damper 20 is in the protection area 11 when the air outlet 12 is opened, that is, the damper 20 is completely away from the air outlet 12, so the damper 20 will not block the air outlet, thereby increasing the air outlet area. When the air conditioner stops running, the damper 20 can close the air outlet 12 to ensure safety. In addition, in this solution, the air outlet 12 is set to multiple, rather than only one larger air outlet, which can avoid safety hazards such as easy entry of foreign objects due to the excessive size of the air outlet 12. And after the multiple air outlets 12 are opened, the air outlet area of ​​the air outlet area is relatively large, which ensures the air outlet effect, improves the performance of the air conditioner and reduces noise.

[0056] Compared with the traditional air outlet grille, the air outlet area of ​​the present invention can be adjusted, and the air outlet area can be enlarged compared with the traditional grille, thereby improving product performance, reducing wind noise, and taking safety requirements into account. The air outlet of the device can be adjusted to seamless closure, and has three protection effects: insect-proof, waterproof, and dust-proof, which improves product reliability. Compared with the traditional grille, the appearance is simpler and more integrated.
