In the indoor unit having the dual louver structure, for convenience of description and distinction, the first link 30 is connected to the first louver 80, and the second link 40 is connected to the second louver 90.

Optionally, one end of the second connecting rod 40 is connected to the second air deflector 90, and the other end is connected to the nut 20, so that the screw rod element 10 is in transmission connection with the second connecting rod 40. Wherein, the second link 40 is symmetrically arranged with the first link 30. During the movement of the double air guide plates, the screw nut 20 drives the first connecting rod 30 and the second connecting rod 40 to synchronously move linearly under the rotation of the screw rod element 10, so as to push the double air guide plates to open or close.

The first connecting rod 30 and the second connecting rod 40 are symmetrically arranged, so that on one hand, the first air deflector 80 and the second air deflector 90 can be ensured to be the same in distance of extending out or retracting into the indoor unit, and on the other hand, the screw rod element 10 and the nut 20 can be uniformly stressed, so that the smoothness of the moving assembly in the moving process is ensured, and blockage and faults are avoided. In the embodiment of the present application, the first link 30 and the second link 40 are symmetrically disposed with respect to the screw member 10 and the nut 20. Wherein the linear movement directions of the first link 30 and the second link 40 are parallel to the axial direction of the screw member 10.

In the embodiment of the present application, the second link 40 has the same structure as the first link 30. Alternatively, both the first link 30 and the second link 40 are provided with the sliding portion 305, or either one is provided with the sliding portion 305. In either case where the first link 30 and the second link 40 are both provided with the sliding portion 305 or where either sliding portion 305 is provided, the stopper plate 50 is provided with at least one corresponding track portion 504. The first link 30 and the second link 40 are symmetrically disposed, and the first link 30 or the second link 40 defines a movement locus through the rail portion 504 of the stopper plate 50, thereby defining a movement locus of the second link 40 or the first link 30.

Under the condition that the moving mechanism of the air deflector comprises the first connecting rod 30 and the second connecting rod 40, the mounting part is positioned in the middle of the edge of the limiting plate 50, and the encloser 70, the mounting part and the limiting plate 50 enclose two extending openings 100, so that the first connecting rod 30 and the second connecting rod 40 respectively extend to push the double air deflectors.

With reference to fig. 1 to 7, an indoor unit according to an embodiment of the present disclosure includes a moving mechanism of an air deflector provided in any one of the embodiments. The motion of aviation baffle includes: the screw rod component 10 is sleeved with a nut 20; a first link 30 having one end connected to the air guide plate and the other end connected to the nut 20 so that the screw element 10 is drivingly connected to the first link 30, the first link 30 having a sliding portion 305; a stopper plate 50 slidably coupled with the sliding portion 305 to define a movement locus of the first link 30; in the moving process of the air deflector, the nut 20 drives the first connecting rod 30 to move linearly along the limiting plate 50 under the rotation of the screw rod element 10, so as to push the air deflector to open or close.

By adopting the indoor unit provided by the embodiment of the disclosure, the movement track of the first connecting rod 30 is limited by the limiting plate 50, and under the rotation motion of the screw rod element 10, the screw nut 20 drives the first connecting rod 30 to make linear motion along the limiting part, so that the first connecting rod 30 pushes the air deflector to extend out, thereby opening or closing the air outlet of the indoor unit. The moving mechanism is simple in structure and is not prone to failure in the moving process of the air deflector.

The above description and drawings sufficiently illustrate embodiments of the disclosure to enable those skilled in the art to practice them. Other embodiments may include structural and other changes. The examples merely typify possible variations. Individual components and functions are optional unless explicitly required, and the sequence of operations may vary. Portions and features of some embodiments may be included in or substituted for those of others. The embodiments of the present disclosure are not limited to the structures that have been described above and shown in the drawings, and various modifications and changes may be made without departing from the scope thereof. The scope of the present disclosure is limited only by the appended claims.
