The driving device 3 is disposed in the machine body 1, and as shown in fig. 3, the driving device 3 is hinged to the air deflector 2 to drive the air deflector 2 to pivot relative to one of the first rotating shaft 21 and the second rotating shaft 22. As shown in fig. 2, the driving device 3 is located on the inner side of the housing member 12, and the driving device 3 is connected to the first edge 23 and the second edge 24 of the wind deflector 2 in a hinged manner, so that the wind deflector 2 pivots relative to the first rotating shaft 21 or the wind deflector 2 pivots relative to the second rotating shaft 22, which effectively provides a sufficient driving force for pivoting the wind deflector 2.

According to the air-conditioning indoor unit 100 of the embodiment of the invention, the first rotating shaft 21 is arranged adjacent to the first edge 23 of the air deflector 2 extending along the length direction, and the second rotating shaft 22 is arranged adjacent to the second edge 24 of the air deflector 2, so that the air deflector 2 rotates around the first rotating shaft 21 and the second rotating shaft 22, and the position of the air outlet 121 is avoided when the air deflector 2 rotates, thereby effectively ensuring the air outlet concentration of the air outlet 121, increasing the adjustable angle and the air supply distance of the air deflector 2, and reducing the gap between the air deflector 2 and the machine body 1.

In some specific embodiments, the first motor 332 and the second motor 342 may be respectively disposed on the bracket 35 near the edge, referring to fig. 7 and 8, the first motor 332 and the second motor 342 are respectively disposed on the left and right sides of the bracket 35, the first motor 332 is located below the left side surface of the bracket 35, and the second motor 342 is located above the right side surface, so that the first motor shaft 331 and the second motor shaft 341 can rotate as many angles as possible while ensuring that the first motor shaft 331 and the second motor shaft 341 are as short as possible, thereby increasing the opening angle of the air deflector 2, and ensuring the compactness and the reasonable layout of the component structure on the driving device 3.

In some alternative embodiments, the first movable member 31 and the second movable member 32 are respectively provided on both side surfaces of the bracket 35. As shown in fig. 7 and 8, the first movable member 31 and the second movable member 32 are respectively provided on the left and right side surfaces of the bracket 35, whereby the movable range of the movable members on each side surface is larger, the arrangement is more convenient, and the processing is simple.

In some alternative embodiments, the first movable member 31, the second movable member 32, the first gear 333, and the second gear 343 may be injection molded using POM (polyformaldehyde) material, but are not limited thereto. Due to the nature of the POM material, the rigidity of the first movable piece 31, the second movable piece 32, the first gear 333 and the second gear 343 can be increased, and meanwhile, the first movable piece 31, the second movable piece 32, the first gear 333 and the second gear 343 have self-lubricating property, so that the abrasion among the first movable piece 31, the second movable piece 32, the first gear 333 and the second gear 343 in the motion process is reduced, and the service life of the driving device 3 is prolonged.

The first movable member 31 is movably disposed between the first arc-shaped groove 351 and the first bracket cover 36, and the first bracket cover 36 can be fixed on the left side surface of the bracket 35 through a threaded fastener such as a screw, and is used for covering the first movable member 31, and swinging the first gear 333 left and right to form a certain limit fixing, and simultaneously avoiding the second gear 343 and the second movable member 32 from coming off. Likewise, the second movable member 32 is movably disposed between the second arcuate slot 352 and the second bracket cover 37. The second bracket cover 37 can be fixed on the right side surface of the bracket 35 by a threaded fastener such as a screw, and is used for covering the second movable member 32, so as to form a certain limit fixing for the second gear 343 to swing left and right, and simultaneously prevent the first gear 333 and the first movable member 31 from being disengaged.

In some embodiments, as shown in fig. 3, the wind deflector 2 may be formed as an arc-shaped plate that is arc-shaped in the width direction, and the arcs of the first movable member 31 and the second movable member 32 are substantially identical to the arc of the wind deflector 2. This improves the overall appearance of the air conditioning indoor unit 100.

In some embodiments of the present invention, as shown in fig. 15-16, the first movable member 31 includes a first arc-shaped body 312, a first contact portion 313 and a first stop portion 314. Specifically, the first rack 311 is disposed on the outer surface of the first arc-shaped body 312, the first contact portion 313 is disposed on the outer surface of the first arc-shaped body 312 and is adjacent to the first rack 311, the height of the first contact portion 313 is higher than the height of the first rack 311, and the first abutting portion 314 is disposed on the first side surface 3121 of the first arc-shaped body 312 away from the first rack 311 and protrudes from the first side surface 3121.

Since the first movable member 31 and the second movable member 32 have the same structure and the same effect when installed, the first movable member 31 will be described in detail below as an example. As shown in fig. 15 to 17, the first rack 311 is disposed on the outer peripheral surface of the first arc-shaped body 312, the first contact portion 313 is disposed on the right side of the first arc-shaped body 312, the first rack 311 and the first contact portion 313 are both located at the upper arc-shaped surface of the first arc-shaped body 312, the first stop portion 314 is disposed on the first side surface 3121 of the first arc-shaped body 312 away from the first rack 311 and protrudes from the first side surface 3121, that is, the first stop portion 314 is located on the right side of the first arc-shaped body 312 and is located below the first contact portion 313, when the first stop portion 314 is installed, the first contact portion 313 contacts with the corresponding arc-shaped inner surface of the first arc-shaped groove 351, and the first stop portion 314 contacts with the bottom surface of the first arc-shaped groove 351. Therefore, the contact area between the first movable member 31 and the first arc-shaped groove 351 is reduced, so that the friction of the first movable member 31 in the movement process is reduced, and the movement smoothness of the first movable member 31 is ensured.

In some alternative embodiments, as shown in fig. 15, the first stopping portion 314 includes two and is formed in an arc shape, the two first stopping portions 314 are disposed in parallel on the first side surface 3121 of the first movable member 31, the first side surface 3121 has a first limiting groove 3141, the first arc-shaped groove 351 on the bracket 35 has an arc-shaped limiting convex strip 353 therein, and as shown in fig. 11, when the first movable member 31 is assembled in the first arc-shaped groove 351, the arc-shaped limiting convex strip 353 is located in the first limiting groove 3141. Correspondingly, the second stopping portion 324 includes two curved second stopping portions 324, the two second stopping portions 324 are disposed in parallel on the second side surface 3221 of the second movable member 32, the second side surface 3221 has a second limiting groove 3241, and the second curved groove 352 on the bracket 35 has a curved limiting protrusion 353 therein, as shown in fig. 12, when the second movable member 32 is assembled in the second curved groove 352, the curved limiting protrusion 353 is located in the second limiting groove 3241.

Since the first abutting portion 314 and the second abutting portion 324 have the same structure, and the first movable element 31 and the second movable element 32 have the same structure, the same effect is obtained when the movable elements are installed, and therefore the first abutting portion 314 and the first movable element 31 are taken as an example for detailed description as follows.
