As shown in fig. 5 to 13, the first sub-driving region has a first tooth 2412a, the first transmission part 22 has a first gear structure 221 for meshing engagement with the first tooth 2412a, and the first sub-intermittent region is an arc-shaped surface. In this way, when the first tooth 2412a of the first sub-driving region rotates to engage with the first gear structure 221, the first sub-driving region drives the first gear structure 221 to rotate, and when the first sub-intermittent region rotates to a side facing the first gear structure 221, the first gear structure 221 cannot engage with the first sub-intermittent region of the arc surface, so that the first gear structure 221 stops rotating and is at the maximum air outlet angle, and the first sub-driving structure 2412 realizes intermittent driving of the first gear structure 221.
As shown in fig. 5 to fig. 13, the second sub-driving region has a second tooth 2413a, the second transmission part 23 has a second gear structure 231 for meshing and matching with the second tooth 2413a, and the second sub-intermittent region is an arc-shaped surface. In this way, when the second tooth 2413a of the second sub-driving region rotates to engage with the second gear structure 231, the second sub-driving region drives the second gear structure 231 to rotate, and when the second sub-intermittent region rotates to the side facing the second gear structure 231, the second gear structure 231 cannot engage with the second sub-intermittent region of the arc-shaped surface, so that the second gear structure 231 stops rotating, and the second sub-driving structure 2413 intermittently drives the second gear structure 231.
It should be noted that, in the present application, except for the two air outlet areas at the two sides of the air outlet 11, the air deflectors 21 in the remaining air outlet areas of the multiple air outlet areas can independently rotate to continuously sweep air. Thus, the air deflectors 21 in the other air outlet areas can independently rotate to continuously sweep air, so that the air conditioner can realize multidirectional air sweeping while supplying air at a wide angle.
In the present application, the continuous wind sweeping means that the wind deflector 21 located in the middle is rotated during the engagement between the second gear 2413a and the second gear structure 231, and the continuous wind sweeping is realized during the rotation.
Of course, except for the two air outlet areas at the two sides of the air outlet 11, the air deflectors 21 in the remaining air outlet areas of the multiple air outlet areas can independently rotate to a preset angle to guide air directionally. Therefore, the air guide plates 21 in the rest air outlet areas in the air outlet areas can independently rotate to a preset angle to conduct directional air guide, the rotation flexibility of the air guide plates 21 is improved, and the diversity of air guide modes is increased.
It should be noted that, in the present application, when the driving motor 2414 drives the first sub-driving structure 2412 and the second sub-driving structure 2413 to synchronously rotate to the preset angle through the transmission shaft 2411, the second tooth 2413a and the second gear structure 231 are engaged and transmitted to the preset angle, and at this time, the air deflector 21 located in the middle stops at the preset angle, so as to implement the above directional air guiding.
As shown in fig. 4, 9-11, the first sub drive structure 2412 and the second sub drive structure 2413 are coaxially arranged; and/or the drive motor 2414 may be disposed coaxially with the intermittent drive structure 241. In this way, while the structure compactness of the intermittent drive structure 241 is ensured, the drive motor 2414 is ensured to be capable of driving the first sub-drive structure 2412 and the second sub-drive structure 2413 to rotate synchronously and concentrically.
As shown in fig. 4 to 13, the position of the first sub-driving structure 2412 having the first sub-driving region is the same as the position of the second sub-driving structure 2413 having the second sub-driving region. In this way, when the first sub-driving region of the first sub-driving structure 2412 drives the first transmission portion 22, the second sub-intermittent region of the second sub-driving structure 2413 faces one side of the second transmission portion 23, so that when the air deflectors 21 located at two sides of the air outlet 11 rotate, the air deflector 21 at the middle position does not rotate, and similarly, when the first sub-intermittent region of the first sub-driving structure 2412 rotates to face one side of the first transmission portion 22, the second sub-driving region of the second sub-driving structure 2413 rotates to face one side of the second transmission portion 23 and is in driving connection with the second transmission portion 23, thereby ensuring the rotation reliability of the air deflector 21 at the middle position.
It should be noted that, in the present application, a first central angle of the first sub-driving region on the first sub-driving structure 2412 is C1, and a second central angle of the second sub-driving region on the second sub-driving structure 2413 is C2, where the first central angle C1 and the second central angle C2 satisfy: c1 is less than or equal to C2. When the first teeth 2412a in the first sub-driving region are disengaged from the first gear structure 221 of the first transmission unit 22, the second teeth 2413a in the second sub-driving region start to be drivingly connected to the second gear structure 231 of the second transmission unit 23, so that the operation timings of the air deflectors 21 are different, and the operation reliability of the air deflectors 21 is ensured.
It should be noted that, in the present application, the diameter of the first gear structure 221 is larger than that of the second gear structure 231, and in order to ensure that the second gear structure 231 starts to rotate while the first gear structure 221 stops rotating, the first sub-driving region and the second sub-driving region are designed such that the first central angle C1 is smaller than the second central angle C2.
Preferably, the first sub-drive region is located at a first central angle C1 of 100 ° on the first sub-drive structure 2412; and/or the second sub-drive region is located at a second central angle C2 of 120 ° on the second sub-drive structure 2413. Thus, the air deflectors 21 on both sides of the outlet 11 can rotate to the position where the opening angle is the largest, and at the same time, the air deflectors 21 in the middle start rotating while the air deflectors 21 on both sides reach the maximum position.
As shown in fig. 4 to 13, the air guiding mechanism 20 further includes a supporting structure 25, and the supporting structure 25 is disposed on the air-out frame 10; each air deflector 21 is rotatably connected with the support structure 25 through a respective pivot shaft 211; the pivot shafts 211 on the air deflectors 21 of the air outlet regions except for the two air outlet regions at the two sides of the air outlet 11 in the air outlet regions penetrate through the support plate of the support structure 25 and are connected with the second gear structure 231 of the second transmission part 23; the pivot shafts 211 on the air deflectors 21 in the two air outlet areas on the two sides of the air outlet 11 respectively penetrate through the support plate and are connected with the two transmission link mechanisms 222 of the first transmission part 22, and the first gear structure 221 of the first transmission part 22 is respectively in driving connection with the two transmission link mechanisms 222. Thus, the arrangement of the support structure 25 provides mounting positions for each of the air guiding plate 21, the first transmission part 22 and the second transmission part 23, and increases the reliability of the connection.
As shown in fig. 4 to 13, the support structure 25 includes a support plate 251 and a mounting plate 252, the mounting plate 252 is disposed on the support plate 251, an avoidance space 100 is provided between the mounting plate 252 and the support plate 251, a first gear structure 221 is disposed on the mounting plate 252 and located at the avoidance space 100, and an end surface of the first gear structure 221 facing the support plate 251 has two gear pivot shafts 2211; the first transmission portion 22 further includes two transmission link mechanisms 222, one end of each of the two transmission link mechanisms 222 is respectively used for being connected to the two gear pivot shafts 2211, and the other end of each of the two transmission link mechanisms 222 is respectively used for being pivotally connected to the two air deflectors 21 at the two side edges. In this way, the first gear structure 221 is disposed on the mounting plate 252, and the two gear pivot shafts 2211 of the first gear structure 221 are respectively connected to the two transmission link mechanisms 222, so that when the first gear structure 221 rotates, the two transmission link mechanisms 222 are driven to move, and the air deflectors 21 in the two air outlet areas at two sides of the air outlet 11 are driven.
In an embodiment of the present application, which is not shown in the drawings, the supporting structure 25 only includes the mounting plate 252, and the air guiding mechanism 20 is mounted on the air-out frame 10, so that the number of parts is reduced, and the assembly efficiency is improved.
Optionally, the driving motor 2414 is installed at both ends of the air outlet frame 10, so that the gap of the air deflector 21 in the closed state can be optimized.

In this way, the transmission link mechanism 222 includes two sub-links 2221 pivotally connected to each other, so that flexibility of the transmission link mechanism 222 is increased, and the lengths of the two sub-links 2221 are different, so that the air deflectors 21 located in the two air outlet areas at the two sides of the air outlet 11 can be opened at the maximum angle, and the air supply area is enlarged.
