Here, "the area covered by the swinging blades 40 is close to the air outlet area of the air outlet defined by the air outlet frame 90" may be understood as follows: in order to avoid the interference between the swing blades 40 and the air outlet frame 90 during the rotation process, or in order to install the moving components of the swing blades 40, a certain gap 603 exists between the swing blades 40 and the air outlet frame 90, so that the area covered by the plurality of swing blades 40 is close to the air outlet area of the air outlet defined by the air outlet frame 90.

This description is made with reference to a wall-mounted air conditioning indoor unit. In the wall-mounted air-conditioning indoor unit, the air outlet is transversely arranged and is of a strip-shaped structure.

The position of the swing blade 40 for closing the air outlet is defined as an initial position, and when the swing blade 40 and the connecting rod 10 are located at the initial position, the two side edges of the swing blades 40 are sequentially abutted or partially overlapped to prevent a gap 603 from being generated. The swing blades 40 include a first edge and a second edge, wherein the first edge 401 and the second edge 402 of two adjacent swing blades are disposed in an abutting or overlapping manner. The first edges 401 of the flaps are located in front of the second flap 40 of another adjacent flap 40, wherein front is understood to be the leeward side of the wind outlet direction.

Optionally, part or all of the flaps 40 are configured with a plurality of hollowed-out portions 403, and the air flows out through the hollowed-out portions 403. Under the condition that the swing blade 40 is located at the initial position, the air flow can flow out through the hollow-out part 403 of the swing blade 40, and a new air outlet mode is realized. The air output and air output strength of the air output mode are both reduced.

One end of the crank 20 is connected to the connecting rod 10, wherein one end of the crank 20 is connected to an end of the connecting rod 10, and the end of the crank 20 and the connecting rod 10 are relatively rotatable. In the case where the crank 20 is driven to rotate by the driver 30, the crank 20 pushes the connecting rod 10 to move along an arc-shaped trajectory in which the end of the crank 20 rotates with respect to the connecting rod 10 to prevent the connecting rod 10 from rotating with respect to the crank 20. In the movement process of the connecting rod 10, the connecting rod 10 drives the swing blades 40 to rotate, an air outlet gap 603 is formed between every two adjacent swing blades 40, and air flow is blown out from the air outlet gap 603 and guided to a corresponding air outlet area through the swing blades 40, so that the purpose of adjusting the air outlet direction is achieved.

Optionally, the connecting rod 10 is divided into a plurality of moving units 101 along the length direction, each moving unit 101 corresponds to one swinging vane 40, and the moving units 101 and the swinging vanes 40 are connected through the first connecting piece 60 to drive the swinging vanes 40 to rotate so as to adjust the wind guiding direction; wherein, the moving unit 101 is rotatably connected with the first connecting member 60, and the swinging vane 40 is fixedly connected with the first connecting member 60.

The connecting rod 10 is divided into a plurality of moving units 101, each moving unit 101 corresponds to one swing blade 40, the plurality of swing blades 40 can be uniformly arranged at intervals on the connecting rod 10, and air outlet flows can be uniformly distributed when the indoor unit is exhausted, so that the user experience is improved.

The top and the bottom of the swing blade 40 are respectively connected to the air outlet frame 90 in a rotating manner, and the straight line of the two rotating connection points is perpendicular to the connecting rod 10. In addition, the straight line is disposed near the first edge 401 of the swing blade or in the region between the symmetrical dividing line of the swing blade 40 in the vertical direction and the first edge. The moving unit 101 is connected to the pivot blade 40 by a first connecting element 60, wherein the first connecting element 60 is arranged close to the second edge 402 of the pivot blade or in the region between the line of symmetry of the pivot blade 40 and the second edge. Thus, under the condition that the connecting rod 10 moves, the first connecting piece 60 can drive the swing blade 40 to rotate so as to open the air outlet and guide air.

The swing blade 40 is located above the link 10 to prevent the swing blade 40 from interfering with the link 10 during rotation.

The top of the first connecting member 60 is fixedly connected to the swing blade 40, and the bottom thereof is inserted through and rotatably connected to the connecting rod 10. In the case of movement of the connecting rod 10, the first connecting member 60 is moved along an arc-shaped trajectory by the connecting rod 10.

when the connecting portion 102 moves from the initial position to the second position, the flap 40 adjusts the outlet airflow so that the airflow is discharged to the left. With the connection portion 102 in the second position, the air flow is blown straight. When the connecting portion 102 moves from the second position to the third position, the flap 40 adjusts the outlet airflow so that the airflow is discharged to the right. Wherein, the swing blade 40 closes the air outlet when the connecting portion 102 is located at the initial position and the third position. Then, the connecting portion 102 moves from the third position to the second position, and moves from the second position to the initial position, so as to reciprocate, and the purpose of adjusting left and right air outlet is achieved.

Alternatively, the connecting portions 102 and the avoiding portions 103 of the plurality of moving units 101 are alternately arranged.
