[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 guide plate 10, a guide vane 20, a first connecting rod 30 and a second connecting rod 40.

[0059] The guide vane 20 and the guide plate 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 guide plate 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 guide plate 10 opens the first air outlet area 1002, the guide plate 10 is in an open position. As shown in Figure 6 , when the guide plate 10 covers the first air outlet area 1002, the guide plate 10 is in a closed position. The 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 air deflector 20 opens the second air outlet area 1003, the air deflector 20 is in an open position. As shown in Figure 6 , when the air deflector 20 covers the second air outlet area 1003, the air deflector 20 is in a closed position.

[0061] The guide plate 10 and the air deflector 20 are arranged to control the first air outlet area 1002 and the second air outlet area 1003 respectively, so that the air outlet area of the air outlet 1001 can be effectively changed to meet the diversified air outlet requirements of people.

[0062] The first connecting rod 30 is connected with the guide plate 10 and is used to drive the guide plate 10 to move between the open position and the closed position. The second connecting rod 40 is connected with the air deflector 20 and is used to drive the 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, in which the first connecting rod 30 and the second connecting rod 40 extend out of the box body 50, and a retracted position, in which the first connecting rod 30 and the second connecting rod 40 retract 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 during movement is avoided.

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

[0067] When the guide plate 10 and the 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 fitting structure.

[0068] When the guide plate 10 and the 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 fitting 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 guide plate 10 and the air deflector 20 are both in the closed position, if the first connecting rod 30 intersects with the limiting structure or the limiting fitting structure, the second connecting rod 40 will interfere with the first connecting rod 30 when the second connecting rod 40 moves along the limiting structure.

[0070] Therefore, when the guide plate 10 and the 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 fitting 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 guide plate 10 is in the open position, the end of the guide plate 10 close to the air deflector 20 in the closed position is located on the inner side of the other end of the guide plate 10; as shown in Figure 14 , when the air deflector 20 is in the open position, the end of the air deflector 20 close to the guide plate 10 in the closed position is located on the inner side of the other end of the 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 guide plate 10 being located above the air deflector 20 as an example, the end of the guide plate 10 close to the air deflector 20 in the closed position is the lower end of the guide plate 10, and the other end of the guide plate 10 is the upper end; the end of the air deflector 20 close to the guide plate 10 in the closed position is the upper end of the air deflector 20, and the other end of the air deflector 20 is the lower end.

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

[0074] During refrigeration, the guide plate 10 is controlled to be open to realize upward air outlet; during heating, the air deflector 20 is controlled to be open to realize downward air outlet.

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

[0076] During the opening of the guide plate 10 and the 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 guide plate 10 to the 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 guide plate 10, and the movement trajectory of the first connecting rod 30 includes an arc segment, which can not only simplify the connection mode of the first connecting rod 30 and the guide plate 10, avoid faults at the connection between the first connecting rod 30 and the guide plate 10, but also realize the closing and opening of the guide plate 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 air deflector 20, and the second sub-connecting rod 403 is rotationally connected with the air deflector 20; wherein when the air deflector 20 moves from the closed position to the open 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 which the serial number 510 in Figure 11 The movement trajectory of the second sub-connecting rod 403 (such as the arc in which the serial number 507 in Figure 7 The movement trajectory of the first sub-connecting rod 402 and the movement trajectory of the second sub-connecting rod 403 intersect, on the one hand, it can reduce the space occupied by the movement of the first sub-connecting rod 402 and the second sub-connecting rod 403, and further reduce the space occupied by the entire air deflector assembly, on the other hand, if they do not intersect, a gear needs to be provided in the related art to mesh with the first sub-connecting rod 402 and the second sub-connecting rod 403 in sequence to realize the predetermined trajectory of the air deflector 20, while in the present application, the first sub-connecting rod 402 and the second sub-connecting rod 403 can start moving at the same time during the opening of the air deflector 20, and do not need to start in sequence, therefore, the intersection of the two can simplify the driving mode of the first sub-connecting rod 402 and the second sub-connecting rod 403, and simplify the structure of the air deflector assembly under the condition that the first sub-connecting rod 402 is rotationally connected with the guide plate 10 and the second sub-connecting rod 403 is rotationally connected with the air deflector 20.

[0081] The movement trajectory of the first sub-connecting rod 402 and the movement trajectory of the second sub-connecting rod 403 are both in the direction from the guide plate 10 to the air deflector 20 when the air deflector 20 moves from the closed position to the open position.

[0082] Optionally, as shown in Figure 6 The rotating connection between the second sub-connecting rod 403 and the air deflector 20 is located on the side of the rotating connection between the first sub-connecting rod 402 and the air deflector 20 that is away from the guide plate 10.

[0083] For example, when the guide plate 10 is located above the air deflector 20, the rotating connection between the second sub-connecting rod 403 and the air deflector 20 is located below the rotating connection between the first sub-connecting rod 402 and the air deflector 20.

[0084] At least one of the movement trajectory of the first sub-connecting rod 402 and the movement trajectory of the second sub-connecting rod 403 can also be a straight line or a non-arc curve when the air deflector 20 moves from the closed position to the open position.

[0085] The first sub-connecting rod 402 and the second sub-connecting rod 403 move simultaneously during the opening of the air deflector 20, i.e., they start moving at the same time and stop moving at the same time, rather than starting moving one after the other, so that the time for the air deflector 20 to move to the target position can be shortened and the response speed of the air deflector can be improved.

[0086] Optionally, as shown in Figure 6 The second sub-connecting rod 403 includes a second sub-connecting rod body 4031 and a transmission rod 4032, the transmission rod 4032 is arranged between the second sub-connecting rod body 4031 and the air deflector 20, one end of the transmission rod 4032 is rotationally connected with the second sub-connecting rod body 4031, and the other end of the transmission rod 4032 is rotationally connected with the air deflector 20.

[0087] The transmission rod 4032 is arranged so that the degree of freedom of movement between the second sub-connecting rod body 4031 and the air deflector 20 is greater than the degree of freedom of movement between the first sub-connecting rod 402 and the air deflector 20, so that the air deflector 20 can be opened in the case that the rotating connection between the second sub-connecting rod 403 and the air deflector 20 is located on the side of the rotating connection between the first sub-connecting rod 402 and the air deflector 20 that is away from the guide plate 10 and the movement trajectory of the first sub-connecting rod 402 and the movement trajectory of the second sub-connecting rod 403 intersect.

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

[0089] Moreover, due to the presence of the transmission rod 4032, the second sub-link 403 has a large degree of freedom of movement with the air deflector 20, and the second sub-link 403 moves more flexibly, so that in the closed position of the air deflector 20, the second sub-link 403 is far away from the air deflector 20, and the first sub-link 402 moves the air deflector 20 close. In this way, in the open position of the air deflector 20, the second sub-link 403 can make a large-angle deflection by virtue of the flexible movement capability and move to a position close to the air deflector 20. 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 far away from the air deflector 20.

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

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

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

[0093] As shown in the figure, Figure 12 The air deflector 20 includes a first end 201 and a second end 202, which are arranged in sequence along the width direction of the air outlet 1001. In the open position of the air deflector 20, the second end 202 of the 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] During the process of moving the air deflector 20 from the closed position to the open position, the movement trajectory of the first sub-link body 4021 is arc-shaped. Due to the deflection angle of the second sub-link 403, the second sub-link 403 pushes the second end 202 of the air deflector 20 to move outward, and the air deflector 20 rotates around the rotation connection between the connecting rod 4022 and the air deflector 20 until it moves to the open position.

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

[0096] The second sub-connecting rod 403 has a stronger deflection capacity than the first sub-connecting rod 402, and therefore, the rotational connection between the second sub-connecting rod 403 and the deflector 20 is arranged close to the second end 202, and the rotational connection between the first sub-connecting rod 402 and the deflector 20 is arranged close to the first end 201, in other words, the rotational connection between the first sub-connecting rod 402 and the deflector 20 and the rotational connection between the transmission rod 4032 and the deflector 20 are sequentially arranged along the direction from the first end 201 to the second end 202.

[0097] Optionally, the 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 when the deflector 20 moves to the open position, the first end 201 is located inside the second end 202.

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

[0100] During the opening process of the guide plate 10, the driving gear 603 first engages with the first gear portion 302. Since the first gear portion 302 is a straight gear, when the driving gear 603 engages with the first gear portion 302, the guide plate 10 can move along a straight line. When the guide plate 10 is in the closed position, the straight line where the first gear portion 302 is located and the guide plate 10 form a non-zero angle, for example, an angle of 90° or close to 90°, so that when the driving gear 603 engages with the first gear portion 302, the guide plate 10 extends outward, where 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 guide plate 10 first extends outward, which can avoid interference between the guide plate 10 and other parts of the indoor unit 100 caused by direct rotation of the guide plate 10 during the opening process.

[0101] After the driving gear 603 disengages from the first gear portion 302, the driving gear 603 engages with the second gear portion 303. Since the second gear portion 303 is an arc-shaped gear extending along the length direction of the first connecting rod 30, when the driving gear 603 engages with the second gear portion 303, the first connecting rod 30 can move in an arc shape, thereby driving the guide plate to rotate.

[0102] The guide plate assembly further includes 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 guide plate 10 in the closed position.

[0104] The guide plate 10 is a curved surface, but each small piece obtained by infinite segmentation of the guide plate 10 can be regarded as a plane. One of the small pieces is provided with a connecting column 101, and the connecting column 101 is rotationally connected with the first sub-connecting rod 402. The first gear portion 302 is perpendicular to the guide plate 10 in the closed position, which means that the first gear portion 302 is perpendicular to the plane where the small piece where the connecting column 101 is located. In this way, when the driving gear 603 engages with the first gear portion 302, the guide plate 10 is pushed out along the axis of the air duct, thereby avoiding interference between the guide plate 10 and other parts of the indoor unit 100 caused by deviation of the guide plate 10.

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

[0106] During the opening process of the guide plate 10, the guide plate 10 is pushed out by a small distance, which can avoid interference between the guide plate 10 and other parts of the indoor unit 100, so the length of the first gear portion 302 is less than the length of the second gear portion 303.

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

[0108] The first connecting rod 30 can be fixedly connected with the guide plate 10 by setting the shape, position and movement track of the first connecting rod 30. Compared with that the first connecting rod 30 is movably connected (for example, rotationally connected) with the guide plate 10, the fixed connection can simplify the connection structure of the first connecting rod 30 and the guide plate 10, and can enhance the reliability of the movement of the guide plate 10.

[0109] Optionally, the drive gear 603 is located in the box body 50, and the first connecting rod 30 moves between the extended position of extending out of the box body 50 and the retracted position of retracting into the box body 50.

[0110] When the first connecting rod 30 is located at the retracted position, the guide plate 10 is at the closed position. When the first connecting rod 30 is at the extended position, the guide plate 10 is at the open position.

[0111] As shown in Figure 9 and Figure 11 The box body 50 is provided with a guide mechanism 502, and the first connecting rod 30 is provided with a guide matching mechanism 304. The guide mechanism 502 and the guide matching mechanism 304 cooperate to guide the movement of the first connecting rod 30 between the extended position and the retracted position, so as to avoid the deviation of the first connecting rod 30 during the movement.

[0112] One of the guide mechanism 502 and the guide matching mechanism 304 is a guide column, and the other is a guide groove. The guide column is located in the guide groove and can move along the guide groove to guide the first connecting rod 30 to move linearly first and then move in an arc shape.

[0113] The guide groove includes a first sub-guide groove 5021 and a second sub-guide groove 5022. During the opening of the 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 linear, and the second sub-guide groove is arc-shaped. When the guide column is located in the first guide groove and cooperates with the first guide groove, the drive gear cooperates with the first gear tooth portion, the first connecting rod moves linearly, and the first guide plate is pushed out; when the guide column is located in the second guide groove and cooperates with the second guide groove, the drive gear cooperates with the second gear tooth portion, the first connecting rod moves in an arc shape, and the first guide plate starts to rotate.

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

[0115] This arrangement enables the drive gear 603 to drive the guide plate 10 to the open position when the drive gear 603 meshes with the first connecting rod 30, and the end of the guide plate 10 close to the air deflector 20 in the closed position is located inside the other end of the guide plate 10.

[0116] The driving device 60 comprises a driving mechanism. The driving mechanism is drivingly connected with the second connecting rod 40, and is used to drive the second connecting rod 40 to move, so as to drive the air deflector 20 to move between the open position and the closed position.

[0117] As shown in Figure 6 , the driving mechanism is arranged between the first connecting rod 30 and the second connecting rod 40.

[0118] The driving mechanism comprises a driving piece 601 and a gear set 602, and the second connecting rod 40 is provided with a gear tooth.

[0119] The gear set 602 is drivingly connected with the driving piece 601 and is engaged with the gear tooth. The driving piece 601 drives the gear set 602 to rotate, and the gear set 602 drives the second connecting rod 40 to move through the gear tooth, so as to realize the opening and closing of the air deflector 20. The axis of the gear set 602 is located between the first connecting rod 30 and the second connecting rod 40, so that the air deflector assembly is compact in structure and small in space occupation.

[0120] The driving piece 601 can be a motor.

[0121] As shown in Figure 8 , the first connecting rod 30 is provided with an avoiding groove 301 for avoiding the gear set 602, so as to avoid the interference between the first connecting rod 30 and the gear set 602.

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

[0123] The first gear 6021 is engaged with the gear tooth of the first sub-connecting rod 402, and the second gear 6022 is engaged with the gear tooth 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 air deflector 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 air deflector 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] Due to the simultaneous movement of the first sub-link 402 and the second sub-link 403, the movement stroke of the first sub-link 402 is greater than that of the second sub-link 403 during the opening of the air deflector 20.

[0127] Optionally, the transmission rod 4032 is provided with a recess 4033, and the connection between the first sub-link 402 and the air deflector 20 is located in the recess 4033 when the air deflector 20 is in the open position.

[0128] As shown in Figure 14 , the transmission rod 4032 moves towards the connecting rod 4022 during the opening of the air deflector 20. The transmission rod 4032 is provided with a recess 4033 to avoid the influence of the connection between the connecting rod 4022 and the air deflector 20 on the movement of the transmission rod 4032.

[0129] Optionally, the second sub-link 403 moves between a retracted position in the box body 50 and an extended position extending out of the box body 50 to drive the air deflector 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-link 403, which cooperate with the first limiting structure 503 and the second limiting structure 505 respectively, to guide the movement of the second sub-link 403 between the retracted position and the extended position.

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

[0131] During the opening of the air deflector 20, the cooperation area of the first limiting structure 503 and the first limiting cooperation structure 4034 decreases, and the cooperation area of the second limiting structure 505 and the second limiting cooperation structure 4036 increases. In other words, during the opening of the air deflector 20, the first limiting structure 503 has a tendency to gradually cooperate with the first limiting cooperation structure 4034, and the second limiting structure 505 gradually deepens the cooperation with the second limiting cooperation structure 4036. Compared with the case where the first limiting structure 503 and the first limiting cooperation structure 4034 cooperate all the time and the cooperation area size does not change, and the second limiting structure 505 and the second limiting cooperation structure 4036 cooperate all the time and the cooperation 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-connecting rod 403, preventing the second sub-connecting rod 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 is 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 is 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-connecting rod 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. Figure 15 and Figure 16As shown, the number of the second limiting protrusions 506 is three, and one second limiting protrusion 506 is located in the second limiting groove 4037 when the air baffle 20 is in the closed position. Figure 17 and Figure 18 As shown, the three second limiting protrusions 506 are all located in the second limiting groove 4037 when the air baffle 20 is in the open position.

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

[0138] Optionally, as shown, Figure 6 The first limiting fitting 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 against one side of the second sub connecting rod body 4031, and the first limiting fitting structure 4034 abuts against 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 the meshing with the gear teeth on the second sub connecting rod body 4031. The first limiting fitting structure 4034 is arranged on the side of the second sub connecting rod body 4031 away from the second gear 6022, so that the opposite 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, Figure 6 The side edge of the second sub connecting rod 403 away from the second gear 6022 protrudes outward to form the first limiting protrusion 4035.

[0141] Optionally, as shown, Figure 7 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 air baffle 20, the first limiting fitting 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 air baffle 20, the second limiting fitting 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, so that 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 sequentially arranged along the direction in which the second sub-connecting rod 403 moves from the retracted position to the extended position; wherein, as shown in 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 deflector 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 deflector 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 guide plate 10, the first sub-connecting rod 402 moves away from the guide plate 10. If the second wall segment 5072 is provided with the first limiting structure 503, it is not convenient to arrange a structure for limiting the first sub-connecting rod 402 on the box body 50.

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

[0148] As shown in Figure 11 The box body 50 further includes a third side wall 509 opposite to the second side wall 508, and the limiting structure includes a third limiting structure 510 arranged on the third side wall 509. 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 11As shown, 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. The third limiting matching protrusion 4024 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 on the third limiting matching structure 4023 and a guiding effect on the movement of the first sub-linkage 402, preventing the first sub-linkage 402 from deviating during movement.

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

[0151] As shown, Figure 11 The third side wall 509 includes a third wall segment 5091 and a fourth wall segment 5092. The third wall segment 5091 corresponds to the first wall segment 5071, and the fourth wall segment 5092 corresponds to the fourth wall segment 5092. 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 includes 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 movement of the first sub-linkage 402.

[0153] As shown, 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. The third limiting groove 511 includes 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 part of the box body 50.

[0155] The fourth wall segment 5092 extends away from the middle part of the box body 50, so that the extension direction of the fourth wall segment 5092 is the same as the movement direction of the second sub-linkage 403 during opening of the air deflector 20. In this way, the second sub-limiting structure 5102 provided on the fourth wall segment 5092 can be matched with the third limiting matching structure 4023.

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

[0157] Embodiments of the second aspect of the application provide an air conditioner comprising an indoor unit 100 and an outdoor unit connected.

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