Referring to fig. 3 and 4, in particular, the induced air control structure includes a fixed ring 100, a drive ring 200, a drive mechanism 300, and a blade assembly including a plurality of blades 400. The fixing ring 100 is fixedly arranged on an air inlet 11 of the indoor unit of the air conditioner. The drive ring 200 is concentrically and rotatably provided on the fixed ring 100. The driving mechanism 300 is connected to the driving ring 200 for driving the driving ring 200 to rotate. The plurality of blades 400 are arranged in a stacking mode along the circumferential direction of the fixing ring 100, the blades 400 are hinged to the fixing ring 100, the driving ring 200 can drive the blades 400 to deflect in the same direction when rotating, and the size of the air induction port 11 can be controlled and adjusted, so that the air induction port 11 can be closed and opened, and the air induction port 11 can be adjusted in any size in an stepless mode. The two sides of the blade assembly are helical lines, and the width of the outer end part of the blade 400 is larger than that of the inner end part of the blade; as shown in fig. 8, the plurality of blades 400 are closed in a spiral radial arrangement, and the induced draft port is completely closed by the inner end portions thereof.
The blade assembly of the induced air control structure controls the size of the induced air port 11 through the blade structure capable of rotating, so that the induced air can be completely opened and closed, and the induced air volume can be controlled at will, so that the requirements of different people on the induced air volume are met; meanwhile, the blades can be closed without any gap, the blades are completely closed to improve the overall attractiveness, and particularly, in a heating mode, a gap is prevented from being reserved in the center to enter the air inducing mode, so that the user experience is reduced.
Specifically, the blade assembly includes twelve blades, three of which have extensions 401 at their inner ends, and are arranged centrosymmetrically. When the blade assembly is closed, the edges of the extensions 401 of the three blades abut against each other, and the induced draft opening 11 is completely closed.
In the present embodiment, the fixed ring 100, the drive ring 200, and the blades 400 are sequentially disposed from the inside to the outside at the induced draft port 11. The width of the fixing ring 100 is greater than the width of the driving ring 200. The fixing ring 100 is provided with an installation part 110, which is fixedly connected with the indoor unit casing at the air inlet 11 through screws. As shown in fig. 7, the blade 400 is preferably of a helical configuration, with the outer end of the blade 400 being wider than the inner end of the blade 400. The outer end of the blade 400 is provided with a rotation shaft 410 and a moving shaft 420. The vane 400 is hinged to the fixing ring 100 by a rotating shaft 410. The driving ring 200 is provided with arc-shaped guide grooves 210, and the moving shaft 420 is disposed in the guide grooves 210. When the driving ring 200 rotates, the moving shaft 420 can be driven to move through the guiding groove 210, and then the blades 400 are driven to deflect in the same direction, so that the inner ends of the blades 400 are close to or far away from each other, and the size adjustment of the air induction port 11 is realized. As shown in fig. 8, when the inner end of each blade 400 rotates to the center position of the induced draft opening 11, the induced draft opening 11 is shielded by the blade 400, and the induced draft opening 11 is in a closed state; when the inner end of each vane 400 is rotated to the inner edge position of the fixing ring 100, the vane 400 is fully opened and the induced draft port 11 is in a fully opened state. By controlling the rotation angle of the blade 400, the adjustment of any size of the induced draft opening can be realized. In this embodiment, for protection, the inner end of each blade 400 is rounded, and when rotating to the innermost limit position, a small-area gap is left at the center, and the induced air port 11 is not completely closed and sealed, but because the induced air port 11 is very small, the induced air amount is negligible. In other embodiments, the blade 400 may be designed to fully close the induced draft, such as a non-radiused helical blade structure, or a long-waisted blade structure.
As shown in fig. 4, specifically, the driving mechanism 300 includes a motor 310, a gear 320 driven by the motor 310, and a gear groove 330 provided on the driving ring 200 and engaged with the gear 320.

The driving limit structure includes a circular arc protrusion 220 provided on the outer circumference of the driving ring 200 and a limit portion 120 provided on the fixing ring 100. The outer wall of the projection 220 is provided with the gear groove 330, and when the drive ring 200 rotates to the limit position, the end of the projection 220 abuts against the stopper 120. In this embodiment, the periphery of the fixing ring 100 is provided with a surrounding frame, the surrounding frame is provided with a notch, the protruding portion 220 of the driving ring 200 extends out of the surrounding frame, two ends of the surrounding frame notch are the limiting portion 120, and when the driving ring 200 rotates, two ends of the protruding portion 220 are abutted against two sides of the surrounding frame notch to realize limiting.
A blade limiting structure is further arranged between the blade 400 and the fixing ring 100 and used for limiting the deflection angle of the blade 400 and preventing the blade 400 from interfering due to too large or too small deflection angle of the blade 400. Specifically, as shown in fig. 7 and 5, the vane restricting structure includes a stopper 430 provided on the vane 400 and a sector groove 140 provided on the fixing ring 100; the stopper 430 is disposed in the sector groove 140.
As shown in fig. 7, the rotation shaft 410 of the vane 400 has a connection portion 411 and a rotation shaft portion 412, the connection portion 411 is connected to the vane 400, and the rotation shaft portion 412 is fitted to the shaft hole 150 of the fixed ring 100. The stopper 430 is connected to one side of the connection portion 411. In order to prevent the rotation shaft 410 of the blade 400 from falling out of the shaft hole 150, in the present embodiment, a snap structure is provided at an end of the rotation shaft part 412, and the snap structure is engaged with the shaft hole 150. The rotation shaft part 412 comprises two semi-cylinders which are oppositely arranged at intervals, the end parts of the two semi-cylinders are provided with inverted parts 4121, the rotation shaft part 412 is clamped into the shaft hole 150 through elastic deformation, and the inverted parts 4121 can prevent the rotation shaft 410 from falling off from the shaft hole 150.
Further, the driving ring 200 is connected to the fixing ring 100 by a rail-and-groove structure. In the present embodiment, as shown in fig. 5 and fig. 6, the fixed ring 100 is circumferentially opened with a plurality of sliding slots 130, the driving ring 200 is correspondingly provided with a plurality of guide rails 230, and the guide rails 230 are correspondingly fitted in the sliding slots 130, so that the driving ring 200 can rotate along the fixed ring 100.
