[0056] The term "and / or" is a description of the association between objects, which means that there can be three relationships. For example, A and / or B means: A or B, or, A and B, the three relationships.

[0057] 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.

[0058] In combination Figures 1-14 As shown in the drawings, the embodiments of the present disclosure provide a guide vane assembly for an indoor unit 100, the indoor unit 100 comprising a shell, the shell being provided with an air outlet 1001, the guide vane assembly comprising a first guide vane 10, a second guide vane 20, a first connecting rod 30 and a second connecting rod 40.

[0059] The second guide vane 20 and the first guide vane 10 are sequentially arranged along the width direction of the air outlet 1001.

[0060] The air outlet 1001 comprises a first air outlet area 1002 and a second air outlet area 1003, which are sequentially arranged along the width direction of the air outlet 1001. The first air deflector 10 is arranged in the first air outlet area 1002 and is used to open or close the first air outlet area 1002. As shown in Figure 13 , when the first air deflector 10 opens the first air outlet area 1002, the first air deflector 10 is in an open position, as shown in Figure 6 , when the first air deflector 10 covers the first air outlet area 1002, the first air deflector 10 is in a closed position. The second air deflector 20 is arranged in the second air outlet area 1003 and is used to open or close the second air outlet area 1003. As shown in Figure 14 , when the second air deflector 20 opens the second air outlet area 1003, the second air deflector 20 is in an open position, as shown in Figure 6 , when the second air deflector 20 covers the second air outlet area 1003, the second air deflector 20 is in a closed position.

[0061] The first air deflector 10 and the second air deflector 20 are arranged to control the first air outlet area 1002 and the second air outlet area 1003 respectively, so as to effectively change the air outlet area of the air outlet 1001 and meet the diversified air outlet requirements of people.

[0062] The first connecting rod 30 is connected with the first air deflector 10 and is used to drive the first air deflector 10 to move between the open position and the closed position. The second connecting rod 40 is connected with the second air deflector 20 and is used to drive the second air deflector 20 to move between the open position and the closed position.

[0063] As shown in Figure 12 , the movement track of the second connecting rod 40 is in an arc shape, and the movement track of the first connecting rod 30 is located on the inner side of the movement track of the second connecting rod 40. The side close to the center of the arc is the inner side, and the side far from the center of the arc is the outer side.

[0064] The movement track of the first connecting rod 30 is located on the center side of the movement track (arc shape) of the second connecting rod 40, so that the space occupied by the movement of the first connecting rod 30 is reduced, thereby reducing the space occupied by the whole air deflector assembly.

[0065] Optionally, the air deflector assembly further comprises a box body 50, the first connecting rod 30 and the second connecting rod 40 move between an extended position of extending out of the box body 50 and a retracted position of retracting into the box body 50. The box body 50 is provided with a limiting structure, and the second connecting rod 40 is provided with a limiting matching structure. The limiting structure and the limiting matching structure are matched to guide the second connecting rod 40 to move between the extended position and the retracted position relative to the box body 50, so that the second connecting rod 40 moves between the extended position and the retracted position according to the preset movement track, and deviation in the movement process is avoided.

[0066] When the second connecting rod 40 is in the extended position, the second air deflector 20 is driven to move to the open position; when the second connecting rod 40 is in the retracted position, the second air deflector 20 is driven to move to the closed position.

[0067] When the first air deflector 10 and the second air deflector 20 are both in the closed position, the first connecting rod 30 is located on the inner side of the limiting structure or the limiting cooperation structure.

[0068] When the first air deflector 10 and the second air deflector 20 are both in the closed position, if the first connecting rod 30 is located on the outer side of the limiting structure or the limiting cooperation structure, the space occupied by the first connecting rod 30 cannot be ignored when designing the entire air deflector assembly, thereby increasing the space occupied by the entire air deflector assembly.

[0069] When the first air deflector 10 and the second air deflector 20 are both in the closed position, if the first connecting rod 30 intersects with the limiting structure or the limiting cooperation structure, it will cause the second connecting rod 40 to interfere with the first connecting rod 30 when moving along the limiting structure.

[0070] Therefore, when the first air deflector 10 and the second air deflector 20 are both in the closed position, the first connecting rod 30 is located on the inner side of the limiting structure or the limiting cooperation structure, which can not only reduce the space occupied by the entire air deflector assembly, but also avoid the movement of the first connecting rod 30 interfering with the second connecting rod 40.

[0071] Optionally, as shown in Figure 13 When the first air deflector 10 is in the open position, the end of the first air deflector 10 in the closed position close to the second air deflector 20 is located on the inner side of the other end of the first air deflector 10; as shown in Figure 14 When the second air deflector 20 is in the open position, the end of the second air deflector 20 in the closed position close to the first air deflector 10 is located on the inner side of the other end of the second air deflector 20, wherein the direction close to the middle of the indoor unit 100 is the inner side, and the direction away from the middle of the indoor unit 100 is the outer side.

[0072] Taking the first air deflector 10 being located above the second air deflector 20 as an example, the end of the first air deflector 10 in the closed position close to the second air deflector 20 is the lower end of the first air deflector 10, and the other end of the first air deflector 10 is the upper end; the end of the second air deflector 20 in the closed position close to the first air deflector 10 is the upper end of the second air deflector 20, and the other end of the second air deflector 20 is the lower end.

[0073] When the first air deflector 10 and the second air deflector 20 are both in the open position, they will be roughly in the shape of an eight-character. The first air deflector can move synchronously or independently.

[0074] The first air deflector 10 is controlled to be opened to realize upward air outlet when refrigerating; and the second air deflector 20 is controlled to be opened to realize downward air outlet when heating.

[0075] Optionally, as shown in Figure 6 and Figure 13 , when the first air deflector 10 moves from the closed position to the opened position, the movement trajectory of the first connecting rod 30 extends from the direction of the second air deflector 20 to the first air deflector 10; as shown in Figure 6 and Figure 14 , when the second air deflector 20 moves from the closed position to the opened position, the movement trajectory of the second connecting rod 40 extends from the direction of the first air deflector 10 to the second air deflector 20.

[0076] During the opening of the first air deflector 10 and the second air deflector 20, the extension direction of the movement trajectories of the first connecting rod 30 and the second connecting rod 40 makes the first connecting rod 30 and the second connecting rod 40 only occupy the space in the direction of the first air deflector 10 to the second air deflector 20, and the space occupation in the width direction of the indoor unit 100 is less, and the structural modification of the indoor unit 100 is small.

[0077] Optionally, the first connecting rod 30 is fixedly connected with the first air deflector 10, and the movement trajectory of the first connecting rod 30 includes an arc segment, which can simplify the connection mode of the first connecting rod 30 and the first air deflector 10, avoid faults at the connection between the first connecting rod 30 and the first air deflector 10, and realize the closing and opening of the first air deflector 10.

[0078] Optionally, the second connecting rod 40 includes a first sub-connecting rod 402 and a second sub-connecting rod 403.

[0079] The first sub-connecting rod 402 is rotationally connected with the second air deflector 20; the second sub-connecting rod 403 is rotationally connected with the second air deflector 20; wherein, when the second air deflector 20 moves from the closed position to the opened position, the movement trajectories of the first sub-connecting rod 402 and the second sub-connecting rod 403 are both arc-shaped.

[0080] The movement trajectory of the first sub-connecting rod 402 (such as the arc in serial number 510 in Figure 11 ) and the movement trajectory of the second sub-connecting rod 403 (such as the arc in serial number 520 in Figure 7The intersection of the arc (where serial number 507 is located) reduces the space occupied by the movement of the first sub-link 402 and the second sub-link 403, further reducing the space occupied by the entire air guide plate assembly. On the other hand, if the two do not intersect, gears need to be set up in related technologies to mesh with the first sub-link 402 and the second sub-link 403 sequentially to achieve the predetermined trajectory of the second air guide plate 20. However, in this application, the first sub-link 402 and the second sub-link 403 can start moving simultaneously during the opening of the second air guide plate 20, without needing to start sequentially. Therefore, the intersection simplifies the driving method of the first sub-link 402 and the second sub-link 403, and simplifies the structure of the air guide plate assembly, when the first sub-link 402 is rotatably connected to the first air guide plate 10 and the second sub-link 403 is rotatably connected to the second air guide plate 20.

[0081] When the second air guide plate 20 moves from the closed position to the open position, the movement trajectory of the first sub-link 402 and the movement trajectory of the second sub-link 403 both extend from the first air guide plate 10 to the second air guide plate 20.

[0082] Optionally, such as Figure 6 As shown, the rotatable connection between the second sub-connecting rod 403 and the second air guide plate 20 is located on the side opposite to the rotatable connection between the first sub-connecting rod 402 and the second air guide plate 20.

[0083] Taking the first air guide plate 10 located above the second air guide plate 20 as an example, the rotatable connection between the second sub-connecting rod 403 and the second air guide plate 20 is located below the rotatable connection between the first sub-connecting rod 402 and the second air guide plate 20.

[0084] When the second air guide plate 20 moves from the closed position to the open position, at least one of the movement trajectories of the first sub-link 402 and the second sub-link 403 can be a straight line or a non-arc curve.

[0085] During the opening of the second air guide plate 20, the first sub-link 402 and the second sub-link 403 move simultaneously, that is, they start moving and stop moving at the same time, rather than starting moving one after the other. This can shorten the time it takes for the second air guide plate 20 to move to the target position and improve the response speed of the second air guide plate.

[0086] Optionally, such as Figure 6 As shown, the second sub-connecting rod 403 includes a second sub-connecting rod body 4031 and a transmission rod 4032. The transmission rod 4032 is located between the second sub-connecting rod body 4031 and the second air guide plate 20. One end of the transmission rod 4032 is rotatably connected to the second sub-connecting rod body 4031, and the other end of the transmission rod 4032 is rotatably connected to the second air guide plate 20.

[0087] The transmission rod 4032 is arranged such that the freedom of movement between the second sub-link main body 4031 and the second air deflector 20 is greater than the freedom of movement between the first sub-link 402 and the second air deflector 20, so that in the case where the rotation connection between the second sub-link 403 and the second air deflector 20 is located on the side of the rotation connection between the first sub-link 402 and the second air deflector 20 that is away from the first air deflector 10 and the movement trajectory of the first sub-link 402 intersects the movement trajectory of the second sub-link 403, the opening of the second air deflector 20 can be realized.

[0088] Optionally, as shown in Figure 6 , when the second air deflector 20 is in the closed position, the second sub-link 403 is located on the side of the first sub-link 402 that is away from the second air deflector 20; as shown in Figure 14 , when the second air deflector 20 is in the open position, the second sub-link 403 is located on the side of the first sub-link 402 that is toward the second air deflector 20, so that when the second air deflector 20 moves from the closed position to the open position, the movement trajectory of the first sub-link 402 intersects the movement trajectory of the second sub-link 403.

[0089] Moreover, due to the presence of the transmission rod 4032, the freedom of movement between the second sub-link 403 and the second air deflector 20 is greater, and the movement of the second sub-link 403 is more flexible, so that in the closed position of the second air deflector 20, the second sub-link 403 is farther away from the second air deflector 20, and the first sub-link 402 moves the second air deflector 20 closer, so that in the open position of the second air deflector 20, the second sub-link 403 can make a large-angle deflection by virtue of its flexible movement capability and move to a position that is closer to the second air deflector 20, and the deflection capability of the first sub-link 402 is weaker than that of the second sub-link 403, and the first sub-link 402 moves to a position that is farther away from the second air deflector 20.

[0090] Optionally, during the opening of the second air deflector 20 from the closed position to the open position, the movement speed of the first sub-link 402 is greater than the movement speed of the second sub-link, the radius of the circle on which the movement trajectory (arc) of the first sub-link 402 lies is greater than the radius of the circle on which the movement trajectory (arc) of the second sub-link lies, and the central angle corresponding to the movement trajectory of the first sub-link 402 is smaller than the central angle corresponding to the movement trajectory of the second sub-link.

[0091] As shown in Figure 6 , the first sub-link 402 includes a first sub-link main body 4021 and a connecting rod 4022.

[0092] The connecting rod 4022 is arranged between the first sub-link main body 4021 and the second air deflector 20, one end of the connecting rod 4022 is fixedly connected with the first sub-link main body 4021 and the connection forms a bend, and the other end of the connecting rod 4022 is rotationally connected with the second air deflector 20.

[0093] As shown in Figure 12 , the second air deflector 20 comprises a first end 201 and a second end 202, which are sequentially arranged along the width direction of the air outlet 1001. In the open position of the second air deflector 20, the second end 202 of the second air deflector 20 is located outside the first end 201, wherein the direction away from the center of the indoor unit 100 is outside, and the direction close to the center of the indoor unit 100 is inside.

[0094] In the process of the second air deflector 20 moving from the closed position to the open position, the movement trajectory of the first sub connecting rod body 4021 is arc-shaped. Due to the deflection degree angle of the second sub connecting rod 403, the second sub connecting rod 403 pushes the second end 202 of the second air deflector 20 to move outward, and the second air deflector 20 rotates around the rotating connection between the connecting rod 4022 and the second air deflector 20 until it moves to the open position.

[0095] The connection between the first sub connecting rod 402 and the second air deflector 20 and the connection between the second sub connecting rod 403 and the second air deflector 20 are sequentially arranged in the direction from the first end 201 to the second end 202.

[0096] The deflection ability of the second sub connecting rod 403 is stronger than that of the first sub connecting rod 402, therefore, the rotating connection between the second sub connecting rod 403 and the second air deflector 20 is arranged close to the second end 202, and the rotating connection between the first sub connecting rod 402 and the second air deflector 20 is arranged close to the first end 201, in other words, the rotating connection between the first sub connecting rod 402 and the second air deflector 20 and the rotating connection between the second sub connecting rod 403 and the second air deflector 20 are sequentially arranged in the direction from the first end 201 to the second end 202.

[0097] Optionally, the air deflector assembly further comprises a driving device 60.

[0098] The driving device 60 is drivingly connected with the first sub connecting rod 402 and the second sub connecting rod 403, for driving the first sub connecting rod 402 and the second sub connecting rod 403 to move at different speeds, and the movement speed of the first sub connecting rod 402 is greater than that of the second sub connecting rod 403, so as to realize that the first end 201 is located inside the second end 202 when the second air deflector 20 moves to the open position.

[0099] Optionally, as shown in Figure 12 , the driving device 60 comprises a driving gear 603. As shown in Figure 8 and Figure 9As shown, the first connecting rod 30 is provided with a first gear portion 302 and a second gear portion 303, and the second gear portion 303 and the first gear portion 302 are sequentially arranged along the movement direction of the first connecting rod 30 in the opening process of the first air baffle 10 (from the closed position to the open position). The first gear portion 302 is a straight gear extending along the length direction of the first connecting rod 30, and the second gear portion 303 is an arc gear extending along the length direction of the first connecting rod 30. The driving gear 603 is engaged with the first gear portion 302 and the second gear portion 303 in sequence in the opening process of the first air baffle 10.

[0100] In the opening process of the first air baffle 10, the driving gear 603 is first engaged with the first gear portion 302. Since the first gear portion 302 is a straight gear, when the driving gear 603 is engaged with the first gear portion 302, the first air baffle 10 can be driven to move along a straight line. When the first air baffle 10 is in the closed position, the straight line where the first gear portion 302 is located has a non-zero angle with the first air baffle 10, for example, the angle is 90° or close to 90°, so that when the driving gear 603 is engaged with the first gear portion 302, the first air baffle 10 extends outward, wherein the direction close to the center of the indoor unit 100 is inward, and the direction away from the center of the indoor unit 100 is outward. The first air baffle 10 first extends outward, which can avoid interference with other parts of the indoor unit 100 caused by direct rotation of the first air baffle 10 in the opening process.

[0101] After the driving gear 603 is disengaged from the first gear portion 302, it is engaged with the second gear portion 303. Since the second gear portion 303 is an arc gear extending along the length direction of the first connecting rod 30, when the driving gear 603 is engaged with the second gear portion 303, the first connecting rod 30 can be driven to move in an arc shape, thereby driving the air baffle to rotate.

[0102] The air baffle assembly further comprises a driving element 604, which can be a motor, for driving connection with the driving gear 603 to drive the driving gear 603 to rotate. The rotation of the driving gear 603 drives the first connecting rod 30 to move.

[0103] Optionally, the first gear portion 302 is perpendicular to the first air baffle 10 in the closed position.

[0104] The first air guide plate 10 is curved, but each small segment of the first air guide plate 10 can be considered a plane after being infinitely divided. One of the small segments is provided with a connecting post 101, which is rotatably connected to the first sub-connecting rod 402. The first gear tooth 302 is perpendicular to the first air guide plate 10 in the closed position, meaning that the first gear tooth 302 is perpendicular to the plane of the small segment on the first air guide plate 10 where the connecting post 101 is located. In this way, when the drive gear 603 meshes with the first gear tooth 302, the first air guide plate 10 is pushed out along the axis of the air duct, avoiding the first air guide plate 10 from being offset and interfering with other parts of the indoor unit 100.

[0105] Optionally, the length of the first gear tooth 302 is less than the length of the second gear tooth 303.

[0106] After the first air guide plate 10 is pushed out a short distance during the opening process, it can avoid interference between the first air guide plate 10 and other parts of the indoor unit 100. Therefore, the length of the first gear tooth 302 is less than the length of the second gear tooth 303.

[0107] Optionally, the first connecting rod 30 is fixedly connected to the first air guide plate 10.

[0108] By setting the shape, position, and movement trajectory of the first link 30, the first link 30 can be fixedly connected to the first air guide plate 10. Compared to the first link 30 being movably connected to the first air guide plate 10 (e.g., rotatably connected), the fixed connection simplifies the connection structure between the first link 30 and the first air guide plate 10 and enhances the reliability of the movement of the first air guide plate 10.

[0109] Optionally, the drive gear 603 is located inside the housing 50, and the first link 30 moves between an extended position extending out of the housing 50 and a retracted position retracting out of the housing 50.

[0110] When the first link 30 is in the retracted position, the first air guide plate 10 is in the closed position. When the first link 30 is in the extended position, the first air guide plate 10 is in the open position.

[0111] like Figure 9 and Figure 11 As shown, the box body 50 is provided with a guide mechanism 502, and the first link 30 is provided with a guide engagement mechanism 304. The guide mechanism 502 and the guide engagement mechanism 304 cooperate to guide the first link 30 to move between the extended position and the retracted position, so as to avoid the first link 30 from deviating during the movement.

[0112] One of the guiding mechanism 502 and the guiding mating mechanism 304 is a guide post and the other is a guide groove. The guide post is located in the guide groove and can move along the guide groove to guide the first connecting rod 30 to first make a linear motion and then make an arc motion.

[0113] The guide groove includes a first sub-guide groove 5021 and a second sub-guide groove 5022. During the opening of the first air guide plate, the first sub-guide groove and the second guide groove are sequentially arranged along the extension direction of the first connecting rod. The first sub-guide groove is straight, and the second sub-guide groove is arc-shaped. When the guide post is located in the first guide groove and engages with it, the drive gear engages with the teeth of the first wheel, the first connecting rod moves linearly, and the first guide plate is pushed outward; when the guide post is located in the second guide groove and engages with it, the drive gear engages with the teeth of the second wheel, the first connecting rod moves arc-shaped, and the first guide plate begins to rotate.

[0114] Optionally, one end of the first link 30 is connected to the first air guide plate 10, and the other end of the first link 30 extends in the direction from the first air guide plate 10 to the second air guide plate 20.

[0115] This configuration allows the drive gear 603 to mesh with the first connecting rod 30, thereby driving the first air guide plate 10 to the open position. When the first air guide plate 10 is in the closed position, the end of the first air guide plate 10 closest to the second air guide plate 20 is located inside the other end of the first air guide plate 10.

[0116] The drive unit 60 includes a drive mechanism. The drive mechanism is driven to move the second link 40, thereby moving the second air guide plate 20 between an open position and a closed position.

[0117] like Figure 6 As shown, the drive mechanism is located between the first link 30 and the second link 40.

[0118] The drive mechanism includes a drive component 601 and a gear set 602, and the second connecting rod 40 is provided with gear teeth.

[0119] The gear set 602 is driven and connected to the drive member 601 and meshes with the gear teeth. The drive member 601 drives the gear set 602 to rotate, and the gear set 602 drives the second connecting rod 40 to move through the gear teeth, so as to realize the opening and closing of the second air guide plate 20. The axis of the gear set 602 is located between the first connecting rod 30 and the second connecting rod 40, which makes the air guide plate assembly compact and occupies little space.

[0120] The drive component 601 can be a motor.

[0121] like Figure 8 As shown, the first link 30 is provided with a clearance groove 301 for avoiding the gear set 602, so as to avoid interference between the first link 30 and the gear set 602.

[0122] Optionally, the first sub-connecting rod 402 is provided with gear teeth; the second sub-connecting rod 403 is provided with gear teeth. The gear set 602 includes a first gear 6021 and a second gear 6022.

[0123] The first gear 6021 is engaged with the gear teeth of the first sub connecting rod 402, and the second gear 6022 is engaged with the gear teeth of the second sub connecting rod 403. The first gear 6021 drives the first sub connecting rod 402 to move, and the second gear 6022 drives the second sub connecting rod 403 to move, so as to jointly drive the second air baffle 20 to move between the open position and the closed position. The first gear 6021 and the second gear 6022 are coaxially connected, and the radii of the first gear 6021 and the second gear 6022 are not equal.

[0124] As shown in Figure 6 , the first gear 6021 and the second gear 6022 are coaxially arranged, so that the angular velocities of the first gear 6021 and the second gear 6022 are the same, but the radii of the first gear 6021 and the second gear 6022 are not equal, so that the movement speeds of the first sub connecting rod 402 and the second sub connecting rod 403 are different, thereby being able to drive the second air baffle 20 to rotate to the open position.

[0125] The radius of the first gear 6021 is greater than the radius of the second gear 6022, so that the movement speed of the first sub connecting rod 402 is greater than the movement speed of the second sub connecting rod 403.

[0126] Since the first sub connecting rod 402 and the second sub connecting rod 403 move at the same time, the movement stroke of the first sub connecting rod 402 is greater than the movement stroke of the second sub connecting rod 403 during the opening of the second air baffle 20.

[0127] Optionally, the transmission rod 4032 is provided with a avoiding groove 4033, and when the second air baffle 20 is in the open position, the connection part of the first sub connecting rod 402 and the second air baffle 20 is located in the avoiding groove 4033.

[0128] As shown in Figure 14 , during the opening of the second air baffle 20, the transmission rod 4032 moves towards the connecting rod 4022. The avoiding groove 4033 is arranged on the transmission rod 4032 to avoid the influence of the connection part of the connecting rod 4022 and the second air baffle 20 on the movement of the transmission rod 4032.

[0129] Optionally, the second sub connecting rod 403 moves between a retracted position located in the box body 50 and an extended position extending out of the box body 50, so as to drive the second air baffle 20 to move between the open position and the closed position; wherein, as shown in Figure 7 , the limiting structure includes a first limiting structure 503 and a second limiting structure 505 provided on the box body 50, as shown in Figure 6 , the limiting cooperation structure includes a first limiting cooperation structure 4034 and a second limiting cooperation structure 4036 provided on the second sub connecting rod 403, which cooperates with the first limiting structure 503 and the second limiting structure 505, so as to guide the second sub connecting rod 403 to move between the retracted position and the extended position.

[0130] During the opening process of the second air deflector 20, the matching area of the first limiting structure 503 and the first limiting matching structure 4034 decreases, and the matching area of the second limiting structure 505 and the second limiting matching structure 4036 increases.

[0131] During the opening process of the second air deflector 20, the matching area of the first limiting structure 503 and the first limiting matching structure 4034 decreases, and the matching area of the second limiting structure 505 and the second limiting matching structure 4036 increases. In other words, during the opening process of the second air deflector 20, the first limiting structure 503 has a tendency to gradually disengage from the first limiting matching structure 4034, and the second limiting structure 505 gradually deepens the matching with the second limiting matching structure 4036. Compared to the case where the first limiting structure 503 and the first limiting matching structure 4034 are matched throughout the opening process of the second air deflector 20, and the matching area size does not change, and the second limiting structure 505 and the second limiting matching structure 4036 are matched throughout the opening process of the second air deflector 20, and the matching area size does not change, the present application can reduce the size of the first limiting structure 503 and the second limiting structure 505, thereby reducing the size of the box body 50.

[0132] One of the first limiting structure 503 and the first limiting matching structure 4034 is a first limiting groove 504, and the other is a first limiting protrusion 4035. The first limiting protrusion 4035 is located in the first limiting groove 504 and can move relative to the first limiting groove 504, so that the first limiting structure 503 has both a limiting effect on the first limiting matching structure 4034 and a guiding effect on the movement of the second sub-link 403, preventing the second sub-link 403 from deviating during movement.

[0133] The number of first limiting protrusions 4035 can be one or more. As shown in Figure 3 and Figure 6 When the number of first limiting protrusions 4035 is one, the matching area of the first limiting structure 503 and the first limiting matching structure 4034 can be reduced, which can be the part of the first limiting protrusion 4035 located in the first limiting groove 504. When the number of first limiting protrusions 4035 is more than one, the matching area of the first limiting structure 503 and the first limiting matching structure 4034 can be reduced, which can be the number of first limiting protrusions 4035 located in the first limiting groove 504.

[0134] The shape of the first limiting groove 504 is arc-shaped and coincides with the movement trajectory of the second sub-link 403.

[0135] One of the second limiting structure 505 and the second limiting matching structure 4036 is a second limiting groove 4037, and the other is a second limiting protrusion 506. The second limiting protrusion 506 is located in the second limiting groove 4037 and can move relative to the second limiting groove 4037, so that the second limiting structure 505 has both a limiting effect on the second limiting matching structure 4036 and a guiding effect on the movement of the second sub connecting rod 403, preventing the second sub connecting rod 403 from deviating during movement.

[0136] The number of second limiting protrusions 506 can be one or more. When the number of second limiting protrusions 506 is one, the matching area of the second limiting structure 505 and the second limiting matching structure 4036 is reduced, which can be the part of the second limiting protrusion 506 located in the second limiting groove 4037. When the number of second limiting protrusions 506 is more than one, the matching area of the second limiting structure 505 and the second limiting matching structure 4036 is reduced, which can be the number of second limiting protrusions 506 located in the second limiting groove 4037 among the plurality of second limiting protrusions 506. As shown in Figure 15 and Figure 16 As shown, the number of second limiting protrusions 506 is three, and one second limiting protrusion 506 is located in the second limiting groove 4037 when the second air deflector 20 is in the closed position. As shown in Figure 17 and Figure 18 As shown, the three second limiting protrusions 506 are all located in the second limiting groove 4037 when the second air deflector 20 is in the open position.

[0137] As shown in Figure 6 The shape of the second limiting groove 4037 is arc-shaped and coincides with the movement trajectory of the second sub connecting rod 403.

[0138] Optionally, as shown in Figure 6 The first limiting matching structure 4034 is located on the side of the second sub connecting rod 403 away from the second gear 6022.

[0139] The second gear 6022 abuts one side of the second sub connecting rod body 4031, and the first limiting matching structure 4034 abuts the other side of the second sub connecting rod body 4031. The second gear 6022 has a certain limiting effect on the second sub connecting rod 403 through meshing with the gear teeth on the second sub connecting rod body 4031. The first limiting matching structure 4034 is arranged on the side of the second sub connecting rod body 4031 away from the second gear 6022, so that both sides of the second sub connecting rod body 4031 can be limited, thereby realizing the stability of the position of the second sub connecting rod body 4031 in the box body 50.

[0140] As shown in Figure 6As shown, the second sub-connecting rod 403 is outwardly convex at a side edge away from the second gear 6022 to form a first limiting protrusion 4035.

[0141] Optionally, as shown, Figure 7 As shown, the box body 50 includes a first side wall 507 and a second side wall 508, and the driving member 601 is arranged on the second side wall 508. The second side wall 508 is connected with the first side wall 507 and the connection forms an angle; wherein the first limiting structure 503 is arranged on the first side wall 507, and the second limiting structure 505 is arranged on the second side wall 508.

[0142] In the early stage of opening of the second guide vane 20, the first limiting cooperation structure 4034 mainly cooperates with the first side wall 507 to limit and guide the second sub-connecting rod 403. In the later stage of opening of the second guide vane 20, the second limiting cooperation structure 4036 mainly cooperates with the second side wall 508 to limit and guide the second sub-connecting rod 403.

[0143] The connection between the first side wall 507 and the second side wall 508 forms an angle, that is, the first side wall 507 and the second side wall 508 are located in different planes. In the case of limiting and guiding the second sub-connecting rod 403, the size of the box body 50 in a certain plane can be reduced, thereby avoiding that the size of the box body 50 in a certain plane direction is too large.

[0144] The first side wall 507 includes a first wall segment 5071 and a second wall segment 5072. The second wall segment 5072 is connected with the first wall segment 5071 and is arranged in sequence along the direction of movement of the second sub-connecting rod 403 from the retracted position to the extended position; wherein, as shown, Figures 2 to 5 The first limiting structure 503 is arranged on the first wall segment 5071, and the second wall segment 5072 is not provided with the first limiting structure 503.

[0145] During the opening process of the second guide vane 20, the second sub-connecting rod 403 moves along an arc. If the second wall segment 5072 is also provided with the first limiting structure 503, the first wall segment 5071 and the second wall segment 5072 both need to be arc-shaped structures, and the connection between the first wall segment 5071 and the second wall segment 5072 needs to be smooth transition.

[0146] During the opening process of the second guide vane 20, the movement trajectory of the first sub-connecting rod 402 intersects with the movement trajectory of the second sub-connecting rod 403. When the second sub-connecting rod 403 moves towards the position close to the first guide vane 10, the first sub-connecting rod 402 moves away from the position of the first guide vane 10. If the second wall segment 5072 is provided with the first limiting structure 503, it is not convenient to arrange a structure on the box body 50 for limiting the first sub-connecting rod 402.

[0147] Optionally, the first sub-connecting rod 402 is drivingly connected with the second air deflector 20 and moves between a retracted position located in the box body 50 and an extended position extending out of the box body 50.

[0148] As shown in Figure 11 , the box body 50 further comprises a third side wall 509 located opposite to the second side wall 508, and the limiting structure comprises a third limiting structure 510 provided on the third side wall 509, and the first sub-connecting rod 402 is provided with a third limiting matching structure 4023 to guide the movement of the first sub-connecting rod 402 between the retracted position and the extended position.

[0149] As shown in Figure 10 and Figure 11 , one of the third limiting structure 510 and the third limiting matching structure 4023 is a third limiting groove 511, and the other is a third limiting matching protrusion 4024, which is located in the third limiting groove 511 and can move relative to the third limiting groove 511, so that the third limiting structure 510 has both a limiting effect and a guiding effect on the movement of the third limiting matching structure 4023, preventing the first sub-connecting rod 402 from deviating during movement.

[0150] The third limiting groove 511 is arc-shaped and coincides with the movement trajectory of the first sub-connecting rod 402.

[0151] As shown in Figure 11 , the third side wall 509 comprises a third wall segment 5091 and a fourth wall segment 5092. The third wall segment 5091 corresponds to the first wall segment 5071; the fourth wall segment 5092 corresponds to the fourth wall segment 5092; wherein the third wall segment 5091 and the fourth wall segment 5092 are respectively provided with a first sub-limiting structure 5101 and a second sub-limiting structure 5102, and the third limiting structure 510 comprises the first sub-limiting structure 5101 and the second sub-limiting structure 5102.

[0152] The first sub-limiting structure 5101 and the second sub-limiting structure 5102 are respectively provided on the third wall segment 5091 and the fourth wall segment 5092, so that the third limiting structure 510 and the third limiting matching structure 4023 can be matched during the movement of the first sub-connecting rod 402.

[0153] As shown in Figure 11 , the first sub-limiting structure 5101 and the second sub-limiting structure 5102 are respectively a first sub-limiting groove and a second sub-limiting groove, and the first sub-limiting groove and the second sub-limiting groove are connected in communication. Among them, the third limiting groove 511 comprises the first sub-limiting groove and the second sub-limiting groove.

[0154] Optionally, along the direction in which the second sub-linkage 403 moves from the retracted position to the extended position, the fourth wall segment 5092 and the second wall segment 5072 extend away from the middle of the box body 50.

[0155] The fourth wall segment 5092 extends away from the middle of the box body 50, such that the extending direction of the fourth wall segment 5092 is the same as the moving direction of the second sub-linkage 403 during the opening of the second air deflector 20. Thus, the second sub-limiting structure 5102 arranged on the fourth wall segment 5092 can cooperate with the third limiting cooperation structure 4023.

[0156] Optionally, the first linkage 30, the first sub-linkage 402 and the second sub-linkage 403 are arranged in sequence along the direction from the third side wall 509 to the second side wall 508.

[0157] The embodiment of the second aspect of the present application provides an air conditioner, comprising an indoor unit 100 and an outdoor unit connected.

[0158] The indoor unit 100 comprises a shell and an air deflector assembly for the indoor unit 100 as described in any one of the above embodiments, the shell is provided with an air outlet 1001, and the first air deflector 10 and the second air deflector 20 are arranged at the air outlet 1001 and in sequence along the width direction of the air outlet 1001.

[0159] The air conditioner provided by the embodiment of the second aspect of the present application has all the beneficial effects of the air deflector assembly for the indoor unit as described in any one of the above embodiments, and thus is not described herein again.
