[0047] It should be noted that the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0048] At present, the air conditioner is provided with a guide vane at the air outlet, and the rotating angle of the guide vane can be controlled to realize the effect of air supply in different directions. In order to improve the stability of the guide vane in the maximum opening angle state and the closed state, a limiting structure needs to be correspondingly arranged in the rotating direction of the guide vane.

[0049] The related technology provides an air conditioner indoor unit, which comprises a framework, a guide vane, a motor and a rotating shaft sleeve. The rotating shaft sleeve is sleeved on the output shaft of the motor and passes through the end plate of the framework to connect the guide vane and the output shaft of the motor into one body. The rotating shaft sleeve is provided with a limiting protrusion, and the end plate of the framework is provided with a first protruding rib and a second protruding rib. When the guide vane is rotated to the maximum opening angle state and the closed state, the limiting protrusion is stopped by the protruding rib, and the rotating angle of the guide vane can be limited.

[0050] In the related technology, the rotating position of the guide vane is limited by the cooperation of the limiting protrusion and the protruding rib. In the closing process of the guide vane, the rotating shaft sleeve may stop at the second protruding rib, but the guide vane is not completely closed, resulting in a gap between the guide vane and the panel.

[0051] To improve the closing degree of the guide vane 20 and avoid the gap between the guide vane 20 and the panel 10 in the closing process, in combination with Figures 1-12 It is shown that the present disclosure provides an air conditioner indoor unit, which comprises a panel 10 and a guide vane 20.

[0052] In combination with Figures 1-3 It is shown that the panel 10 is provided with an air outlet 11, and the guide vane 20 is arranged on the air outlet 11. The guide vane 20 can move relative to the panel 10 between an opening position for opening the air outlet 11 and a closing position for closing the air outlet 11. The panel 10 is provided with a first limiting part 12, and the guide vane 20 is provided with a first limiting matching part 21. The first limiting part 12 cooperates with the first limiting matching part 21 to make the guide vane 20 fit the panel 10 in the closing position.

[0053] The air conditioner indoor unit provided by the present disclosure has the first limiting part 12 arranged on the panel 10 and the first limiting matching part 21 arranged on the guide vane 20, so that the guide vane 20 can be self-limited in the closing position, thereby improving the accuracy of the limiting. The first limiting part 12 and the first limiting matching part 21 cooperate to limit the guide vane 20 in the closing position, and make the guide vane 20 tightly fit the panel 10. In this way, the guide vane 20 can be accurately positioned in the closing position, the closing degree of the guide vane 20 can be improved, and the gap between the guide vane 20 and the panel 10 in the closing position can be avoided.

[0054] Optionally, in combination with Figure 3 and Figure 12 It is shown that the first limiting part 12 comprises a limiting surface 121, and the first limiting matching part 21 comprises a limiting matching surface 211. The limiting surface 121 corresponds to the limiting matching surface 211, so that the limiting surface 121 fits the limiting matching surface 211 in the closing position of the guide vane 20.

[0055] The limiting surface 121 is arranged on the panel 10, and the limiting matching surface 211 is arranged on the air deflector 20. When the air deflector 20 is in the closed position, the limiting surface 121 and the limiting matching surface 211 are in close contact, which can improve the sealing between the air deflector 20 and the panel 10. The close contact between the limiting surface 121 and the limiting matching surface 211 can provide a stable limiting contact surface and improve the stability of the air deflector 20. At the same time, the air deflector 20 and the panel 10 are directly closed and limited by the close contact between the limiting surface 121 and the limiting matching surface 211, which simplifies the limiting structure and reduces the manufacturing cost and assembly complexity.

[0056] Optionally, in combination with Figure 12 As shown in the figure, the limiting surface 121 is arranged on the air outlet side wall 111 along the length direction of the air outlet 11, and the limiting surface 121 extends along the length direction of the air outlet 11. The limiting matching surface 211 is arranged on the air deflector side edge 22 along the length direction of the air deflector 20, and the limiting matching surface 211 extends along the length direction of the air deflector 20.

[0057] The length direction of the air outlet 11 is as Figure 12 shown in the figure. The length direction of the air deflector 20 is as Figure 1 shown in the figure.

[0058] For the vertical air deflector 20, one side edge of the air deflector 20 along the length direction of the air deflector 20 is rotationally connected with the skeleton 30 of the air conditioner indoor unit, so as to realize the rotation of the air deflector 20 relative to the air outlet 11. The other side edge of the air deflector 20 along the length direction of the air deflector 20 can move relative to the air outlet 11 between the open position and the closed position, and can serve as the closed side of the vertical air deflector to open or close the air outlet 11. When the closed side of the vertical air deflector 20 is in close contact with the air outlet side wall 111, the sealing of the air deflector to the air outlet 11 can be improved.

[0059] The limiting matching surface 211 is arranged on the air deflector side edge 22 along the length direction of the air deflector 20, so that the closed side of the air deflector 20 can be limited. The limiting surface 121 extends along the length direction of the air outlet 11, and the limiting matching surface 211 extends along the length direction of the air deflector 20, which can provide a continuous contact surface for the limiting of the limiting surface 121 and the limiting matching surface 211, and improve the limiting effect of the air deflector 20 in the closed position. The continuous contact surface can also uniformly distribute the pressure on the limiting surface 121, thereby enhancing the stability of the air deflector 20.

[0060] The surface of the air outlet side wall 111 along the length direction of the air outlet 11 is entirely arranged as the limiting surface 121, and the surface of the air deflector side edge 22 along the length direction of the air deflector 20 is entirely arranged as the limiting matching surface 211, so that the closed side of the air deflector 20 can be limited. In this way, the surface of the air deflector side edge 22 can be in close contact with the surface of the air outlet side wall 111, which effectively improves the limiting effect and the sealing effect of the air deflector 20 in the closed position.

[0061] It can be understood that the air outlet side wall 111 along the width direction of the air outlet 11 can also be provided with a limiting surface 121, and a limiting matching surface 211 is arranged on the side edge 22 of the air deflector 20.

[0062] Optionally, in combination with Figure 3 As shown in the figure, the limiting surface 121 and the air outlet side wall 111 are connected by a reinforcing rib 13.

[0063] By arranging the reinforcing rib between the limiting surface 121 and the air outlet side wall 111, the limiting surface 121 can be provided with supporting force, and the strength of the structure of the limiting surface 121 is enhanced. When the air deflector 20 moves to the closed position, the limiting surface 121 is in close contact with the limiting matching surface 211, and the arrangement of the reinforcing rib can avoid or reduce the deformation or damage of the limiting surface 121 caused by external force, thereby improving the durability of the limiting surface 121.

[0064] Optionally, the number of reinforcing ribs 13 is multiple, and the multiple reinforcing ribs 13 are distributed along the length direction of the air outlet 11.

[0065] The arrangement of multiple reinforcing ribs 13 can effectively increase the rigidity of the limiting surface 121, and avoid or reduce the bending or twisting under high wind pressure or external force of the air deflector 20. The multiple reinforcing ribs 13 are distributed along the length direction of the air outlet 11, which can more evenly distribute the load of the limiting surface 121. In this way, the local stress concentration can be reduced, thereby reducing the risk of fracture or damage of the limiting surface 121 caused by stress concentration.

[0066] Optionally, in combination with Figure 2 and Figure 3 As shown in the figure, the limiting surface 121 includes a guide section 122, and the guide section 122 is located at one end of the air outlet side wall 111 close to the air deflector 20. The guide section 122 is inclined to the inside of the air outlet 11 along the direction of the air deflector 20 towards the air outlet 11; the limiting matching surface 211 includes a guide matching section 212, and the guide matching section 212 is located at one end of the air deflector side edge 22 close to the air outlet 11. The guide matching section 212 is inclined to the inside of the air deflector 20 along the direction of the air deflector 20 towards the air outlet 11.

[0067] The direction of the air deflector 20 towards the air outlet 11 is as shown in the figure. Figure 2

[0068] ​The limiting surface 121 comprises a guide segment 122 located at one end of the air outlet sidewall 111 close to the air deflector 20, and the guide segment 122 is inclined towards the inside of the air outlet 11 along the direction of the air deflector 20 towards the air outlet 11, which can guide the limiting cooperation surface 211 to move accurately and smoothly to the closed position and tightly fit with the limiting surface 121. The guide cooperation segment 212 is inclined towards the inside of the air deflector 20 along the direction of the air deflector 20 towards the air outlet 11, so that the guide cooperation segment 212 can cooperate with the guide segment 122 to reduce the resistance of the air deflector 20 during the closing process, and more effectively realize the guiding effect. In this way, the movement of the air deflector 20 can be more smooth.

[0069] Optionally, in combination with Figures 4-9 As shown, the air conditioner indoor unit further comprises a framework 30 and a rotating shaft 40, a first end 41 of the rotating shaft 40 is connected with the air deflector 20, and a second end 42 of the rotating shaft 40 is rotationally connected with the framework 30; wherein the framework 30 is provided with a second limiting portion 31, and the second end 42 of the rotating shaft 40 is provided with a second limiting cooperation portion 43, and the second limiting portion 31 cooperates with the second limiting cooperation portion 43 to limit the air deflector 20 at the open position.

[0070] The second limiting portion 31 is arranged on the framework 30, and the second limiting cooperation portion 43 is arranged on the second end 42 of the rotating shaft 40, and through the cooperation of the second limiting portion 31 and the second limiting cooperation portion 43, the accurate limiting of the air deflector 20 at the open position can be realized. In this way, the stability of the air deflector 20 at the open position can be improved, and the air deflector 20 can be prevented from moving accidentally due to vibration or wind force.

[0071] Optionally, in combination with Figure 11 As shown, the second limiting portion 31 comprises a limiting rib 311, and the second limiting cooperation portion 43 comprises a limiting protrusion 431, and when the air deflector 20 is at the open position, the limiting rib 311 abuts against the limiting protrusion 431.

[0072] The limiting rib 311 is arranged on the framework 30, and the limiting protrusion 431 is arranged on the second end 42 of the rotating shaft 40. The air deflector 20 is rotationally connected with the framework 30 through the rotating shaft 40. When the air deflector 20 moves between the open position and the closed position, the rotating shaft 40 rotates relative to the framework 30, and the limiting protrusion 431 rotates synchronously with the second end 42 of the rotating shaft 40. When the air deflector 20 moves to the open position, the limiting protrusion 431 rotates to abut against the limiting rib 311, which can prevent the rotating shaft 40 from rotating excessively. In this way, the stability of the air deflector 20 at the open position can be improved.

[0073] Optionally, in combination with Figure 7 and Figure 11As shown, the framework 30 comprises an end plate 32, the end plate 32 is provided with a through hole 321, the rotating shaft 40 is arranged in the through hole 321; the limiting rib 311 is arranged on the end plate 32, and the limiting protrusion 431 is arranged along the radial direction of the rotating shaft 40.

[0074] The first end 41 of the rotating shaft 40 is connected with the air deflector 20, the second end 42 of the rotating shaft 40 is rotationally connected with the framework 30, and the limiting protrusion 431 is arranged on the second end 42 of the rotating shaft 40. The rotating shaft 40 is arranged in the through hole 321, and the first end 41 and the second end 42 of the rotating shaft 40 are located on both sides of the through hole 321. The limiting protrusion 431 is arranged along the radial direction of the rotating shaft 40, which is convenient for abutting against the limiting rib 311. The limiting protrusion 431 is arranged along the radial direction of the rotating shaft 40, which makes the limiting structure more compact and reduces the occupation of the space outside the end plate 32. At the same time, the limiting protrusion 431 is arranged along the radial direction of the rotating shaft 40, which can also prevent the rotating shaft 40 from being separated from the through hole 321.

[0075] Optionally, in combination with Figure 5 As shown, the framework 30 is provided with a guide rail 33, the second limiting part 31 is arranged at one end of the guide rail 33, and the second limiting matching part 43 is matched with the guide rail 33, so that the second limiting matching part 43 moves towards or away from the second limiting part 31 along the guide rail 33.

[0076] The arrangement of the guide rail 33 enables the second limiting matching part 43 to move along a predetermined path when the air deflector 20 moves, which improves the accuracy of the cooperation between the second limiting part 31 and the second limiting matching part 43. When the air deflector 20 moves towards the open position, the guide rail 33 guides the second limiting matching part 43 to move towards the second limiting part 31, so that the second limiting part 31 can cooperate with the second limiting matching part 43 to limit the air deflector 20 at the open position. When the air deflector 20 moves towards the closed position, the guide rail 33 guides the second limiting matching part 43 to move away from the second limiting part 31, so that the second limiting part 31 can be disengaged from the second limiting matching part 43. At the same time, the guide rail 33 can also improve the stability of the second limiting matching part 43 when it moves, so that the air deflector 20 can smoothly transition between the open and closed positions.

[0077] Optionally, in combination with Figure 5 As shown, the second limiting matching part 43 abuts against the guide rail 33, and the second limiting matching part 43 can slide relative to the guide rail 33.

[0078] The abutment of the second limiting matching part 43 and the guide rail 33 enables the surface of the second limiting matching part 43 to slide directly along the extension direction of the guide rail 33. This can reduce the need for additional sliding cooperation structures and reduce the complexity of assembly.

[0079] Optionally, in combination with Figure 5 As shown, the guide rail 33 extends along the circumference of the rotating shaft 40.

[0080] The second limiting fitting part 43 is arranged at the second end 42 of the rotating shaft 40, so that the second limiting fitting part 43 can move synchronously when the rotating shaft 40 rotates. The rotating shaft 40 rotates along the circumference of the rotating shaft 40, and the guide rail 33 extends along the circumference of the rotating shaft 40, so as to provide a continuous movement path for the second limiting fitting part 43. In this way, the smoothness of the second limiting fitting part 43 during movement can be improved. The extension of the guide rail 33 along the circumference of the rotating shaft 40 can also reduce local stress concentration, thereby improving the durability of the guide rail 33.

[0081] Optionally, in combination with Figure 11 Figure 11 As shown in the drawings, the guide rail 33 includes a first track 331 and a second track 332, and the first track 331 and the second track 332 are arranged in a spaced manner, and the second limiting fitting part 43 abuts against the first track 331 and the second track 332.

[0082] The second limiting fitting part 43 abuts against the first track 331 and the second track 332, and friction is formed between the second limiting fitting part 43 and the guide rail 33 when the second limiting fitting part 43 moves along the guide rail 33. The first track 331 and the second track 332 are arranged in a spaced manner, so that a gap is formed between the first track 331 and the second track 332, thereby reducing the contact area between the second limiting fitting part 43 and the guide rail 33. In this way, the friction and wear between the second limiting fitting part 43 and the guide rail 33 can be reduced, so that the movement of the second limiting fitting part 43 is smoother, and the service life of the guide rail 33 and the second limiting fitting part 43 is improved.
