[0048] 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.

[0049] The present disclosure provides an air conditioner and an air conditioner indoor unit.

[0050] Optionally, the air conditioner indoor unit is a large guide plate type air conditioner indoor unit. In the air supply process, the air guide plate 50 first extends out of the air outlet of the air conditioner indoor unit and then rotates to guide the air. In this way, the air guide plate 50 is far away from the air outlet, and the air resistance of the air flow blown out of the air conditioner is small, which can reduce the noise generated at the air guide plate 50 during air supply. At the same time, compared with rotating the air guide plate 50 at the air outlet to supply air, rotating the air guide plate 50 outside the air outlet can supply air in a larger angle and a larger range, thereby improving the cooling or heating effect of the air conditioner. Optionally, the air conditioner indoor unit provided by the present disclosure can also be a cabinet machine or a ducted machine.

[0051] In some embodiments, the air conditioner indoor unit comprises the following drive mechanism for the air guide plate 50.

[0052] Optionally, the drive mechanism is arranged on both sides of the air guide plate 50, and the drive mechanisms on both sides simultaneously drive the air guide plate 50 to move. The following drive mechanism can drive the air guide plate 50 to extend out of the air outlet to a first preset position, and then drive the air guide plate 50 to rotate. The structure and working process of the drive mechanism are described in detail below.

[0053] The present disclosure also provides a drive mechanism for an air guide plate of an air conditioner, as shown in Figures 1 to 15 .

[0054] Figure 2 The first transmission shaft of the rocker is shown in Figure 4 when the air guide plate closes the air outlet, which can also be called the centering position of the first transmission shaft of the rocker.

[0055] In some embodiments, the driving mechanism for the air deflector 50 includes a rocker 10, a driving slider 20, a driven slider 30, and a track plate 40. The rocker 10 is provided with a first transmission shaft 121. The driving slider 20 is provided with a sliding groove 21. One end of the driving slider 20 is rotationally connected to the air deflector 50. The first transmission shaft 121 is slidingly arranged in the sliding groove 21. One end of the driven slider 30 is rotationally connected to the air deflector 50. The track plate 40 is provided with a track portion for limiting the movement of the driving slider 20 and the driven slider 30. The rocker 10 drives the driving slider 20 and the driven slider 30 to move under the limitation of the track portion through the sliding of the first transmission shaft 121 in the sliding groove 21, so that the air deflector 50 is first extended out of the air outlet to a first preset position and then rotated.

[0056] As shown in FIG. 1, Figure 4 When the air deflector closes the air outlet, the first transmission shaft 121 is at the center position of the sliding groove. The upper edge of the center position of the sliding groove is provided with an elastic abutting piece. The first transmission shaft 121 abuts against the elastic abutting piece. The first transmission shaft 121 drives the driving slider 20 to move upward, so that the driving slider 20 pulls the air deflector to close the air outlet.

[0057] When the air deflector is controlled to close the air outlet, the first transmission shaft 121 slides along the sliding groove and gradually moves to the center position of the sliding groove. When the first transmission shaft 121 of the rocker 10 moves to the center position of the sliding groove, the first transmission shaft 121 abuts against the elastic abutting piece, so that the first transmission shaft 121 drives the driving slider 20 to move upward. The driving slider 20 pulls the air deflector to close the air outlet during the upward movement of the driving slider 20.

[0058] The driving mechanism of the air deflector of the air conditioner provided by the embodiments of the present disclosure can generate a force to drive the driving slider 20 to move upward during the closing process of the air deflector, and then pull the air deflector to close the air outlet. The problem of the gap between the air deflector and the frame at the air outlet caused by the manufacturing error and the installation gap of the air deflector is overcome. The closing tightness of the air deflector and the air outlet is improved, and the appearance of the indoor unit of the air conditioner is improved.

[0059] It can be understood that the upward movement of the driving slider 20 is not limited to vertical upward movement, but can also be inclined upward movement in the movement direction of the driving slider 20, as long as the driving slider 20 can pull the air deflector to close the air outlet in this direction.

[0060] Optionally, the elastic abutting piece includes a protruding portion protruding from the sliding groove. The first transmission shaft 121 is in interference fit with the protruding portion at the center position. The elastic abutting piece is deformed to drive the driving slider 20 to move upward.

[0061] The elastic abutting piece is protrudingly arranged inside the sliding groove. The elastic abutting piece is provided with a protruding portion protruding inside the sliding groove. When the air deflector closes the air outlet, the first transmission shaft 121 of the rocker 10 is in interference fit with the protruding portion of the elastic abutting piece at the centering position, the elastic abutting piece is extruded by the first transmission shaft 121, and is deformed. At the same time, the elastic abutting piece on the driving sliding block 20 is subjected to the upward thrust force generated by the extrusion, and further makes the first transmission shaft 121 of the rocker 10 thrust the driving sliding block 20 to move upward.

[0062] Optionally, the elastic abutting piece can be an elastic material that is deformed by the extrusion of the first transmission shaft 121 and can restore the original shape when not extruded by the first transmission shaft 121, such as a spring, a spring piece 28, rubber, sponge, latex, etc.

[0063] Optionally, the shape of the elastic abutting piece can be semicircular, semi-elliptical, ladder-shaped, arch bridge-shaped or other irregular shapes with protrusions.

[0064] Optionally, the elastic abutting piece includes a spring piece 28. The spring piece 28 includes a first connecting end 281, a second connecting end 282 and a protruding segment 283. The first connecting end 281 is fixedly connected with the upper edge, the second connecting end 282 is fixedly connected with the upper edge, and the protruding segment 283 is arranged between the first connecting end 281 and the second connecting end 282. The protruding segment 283 is provided with a deformation space to the upper edge. At the centering position, the protruding segment 283 is extruded by the first transmission shaft 121 to the deformation space to thrust the driving sliding block 20 to move upward. Figures 6 to 8

[0065] The protruding segment 283 to the upper edge is not solidly arranged, i.e. the protruding segment 283 to the upper edge is provided with a deformation space. When the first transmission shaft 121 extrudes the protruding segment 283 of the spring piece 28, the protruding segment 283 is deformed into the deformation space, and at the same time generates an extrusion force, which drives the driving sliding block 20 to move upward. Optionally, the protruding segment 283 is flat or arc-shaped.

[0066] Optionally, the spring piece 28 further includes a first abutting guide segment 284 and a second abutting guide segment 285. The first abutting guide segment 284 is arranged between the first connecting end 281 and the protruding segment 283, and the second abutting guide segment 285 is arranged between the second connecting end 282 and the protruding segment 283. The distance from the first abutting guide segment 284 and the second abutting guide segment 285 to the upper edge is less than the distance from the protruding segment 283 to the upper edge.

[0067] ​Optionally, the first abutting guide section 284 can be an arc or an inclined surface connecting the first connecting end 281 and the protruding section 283, to guide the first transmission shaft 121 of the rocker 10 to slide along the first abutting guide section 284 and to the protruding section 283 of the elastic sheet 28. The second abutting guide section 285 can be an arc or an inclined surface connecting the second connecting end 282 and the protruding section 283, to guide the first transmission shaft 121 of the rocker 10 to slide along the second abutting guide section 285 until disengaging from the elastic sheet 28. The distance from the first abutting guide section 284, the second abutting guide section 285 and the protruding section 283 to the upper edge can be understood as the vertical distance from the first abutting guide section 284, the second abutting guide section 285 and the protruding section 283 to the upper edge, respectively.

[0068] Optionally, the distance from the protruding section 283 to the upper edge is less than or equal to the radius of the first transmission shaft 121.

[0069] Due to the manufacturing error and assembly gap of the air deflector, the gap between the air deflector and the frame of the air outlet is small. Based on this, the distance from the protruding section 283 to the upper edge does not have to be very large, and can be less than or equal to the radius of the first transmission shaft 121. If the distance from the protruding section 283 to the upper edge is too large, it will also affect the normal sliding of the first transmission shaft 121 of the rocker 10 along the sliding groove.

[0070] Optionally, the lower edge at the center position of the sliding groove is provided with a recess 29 avoiding the first transmission shaft 121. As shown in Figure 5 and Figure 6 .

[0071] When the first transmission shaft 121 abuts against the elastic abutting piece, the first transmission shaft 121 will also move slightly downward. The lower edge at the center position of the sliding groove is provided with a recess 29 avoiding the downward movement of the first transmission shaft 121, providing space for the downward movement of the first transmission shaft 121. Optionally, the downward movement of the first transmission shaft 121 is limited, and the vertical distance from the recess 29 to the lower edge does not have to be too large, and can be less than or equal to the radius of the first transmission shaft 121.

[0072] The following embodiments describe the rocker, the driving block, the driven block, the track plate and other structures in the driving mechanism of the air deflector of an air conditioner, and the rotation process of the driving mechanism driving the air deflector.

[0073] Optionally, the driving force of the movement of the active slider 20 comes from the rocker 10. The rocker 10 provides the driving force of the movement of the active slider 20 through the sliding of the first transmission shaft 121 in the sliding groove 21. The active slider 20 and one end of the driven slider 30 are connected with the air deflector 50, and the driving force is transmitted to the driven slider 30 through the air deflector 50 and the connection point of the driven slider 30, so as to drive the movement of the driven slider 30. The active slider 20 and the driven slider 30 drive the air deflector 50 to extend out of the air outlet to the first preset position under the limitation of the track plate 40, and then drive the air deflector 50 to rotate. In this way, one rocker 10 can drive the movement of the slider assembly, and then drive the air deflector 50 to extend out of the air outlet and rotate to guide the air. The cooperation relationship of the driving mechanism is close and the structure is simple. At the same time, the air deflector 50 extends out of the air conditioner and rotates to guide the air at a large angle, thereby expanding the air supply range of the air conditioner.

[0074] Optionally, the active slider 20 and the driven slider 30 are rotationally connected with the air deflector 50. Optionally, one end of the active slider 20 is provided with a first connection hole 27, and one end of the driven slider 30 is provided with a second connection hole 34.

[0075] Optionally, the active slider 20 is further provided with at least two sliding columns moving along the track part, including a first sliding column 25 at the top and a second sliding column 26 at the middle.

[0076] Optionally, the second plate surface of the driven slider 30 opposite to the first plate surface is provided with three sliding columns, which are arranged in a triangular shape, as shown in Figure 11 , which are a third sliding column 31, a fourth sliding column 32 and a fifth sliding column 33. In this way, the limiting effect of the track plate 40 on the movement track of the driven slider 30 is improved.

[0077] Optionally, the driven slider 30 is provided with a through sliding channel 35 penetrating through the plate surface thereof, and the plate surface of the active slider 20 opposite to the driven slider 30 is provided with a sliding column, which penetrates through the through sliding channel 35 and moves along the track part.

[0078] Optionally, the track part includes a first track and a second track. The first track is in a herringbone shape and is used to limit the movement direction changing of the active slider 20. The second track is in a straight line shape and is arranged on the lower side of the first track along the extending direction of the air deflector 50, and is used to limit the straight line movement of the driven slider 30. Under the constraint of the first track and the second track, the active slider 20 and the driven slider 30 first synchronously move in a straight line to drive the air deflector 50 to move to the first preset position, and then the active slider 20 moves in a changed direction to generate relative movement with the driven slider 30, thereby driving the air deflector 50 to rotate.

[0079] In the embodiment of the present disclosure, the first preset position is the position where the air deflector 50 translates and extends out of the air conditioner and is about to start rotating, as shown inFigure 13 As shown, at this time, the air deflector 50 has a certain distance from the air outlet, and the air deflector 50 can be opened upward or downward at the first preset position. In the embodiment of the present disclosure, the rotating position of the air deflector 50 is not limited to the first preset position, and the first preset position is the initial position of the rotation of the air deflector 50. The rotation of the air deflector 50 can be understood as stretching out and rotating.

[0080] Optionally, the first track includes a first straight track 41, a first branch track 42 and a second branch track 43; the first branch track 42 is in communication with the first straight track 41, the second branch track 43 is in communication with the first straight track 41, and the extension directions of the first branch track 42 and the second branch track 43 are different.

[0081] In the embodiment of the present disclosure, the first sliding column 25 of the driving slider 20 moves in the first track, and the second sliding column 26 of the driving slider 20 moves in the second track. When the first sliding column 25 moves from the first straight track 41 to the first branch track 42 or the second branch track 43, the driving slider 20 will produce relative motion with the driven slider 30, and the driving slider 20 will change the direction of motion.

[0082] Optionally, the second track includes three straight tracks, i.e., a second straight track 44, a third straight track 45 and a fourth straight track 46. In the stretching and rotating process of the air deflector 50, the driven slider 30 always moves linearly along the three straight tracks of the second track. Among them, the third sliding column 31 moves in the second straight track 44, the fourth sliding column 32 moves in the third straight track 45, and the fifth sliding column 33 moves in the fourth straight track 46. That is, the driven slider 30 moves linearly under the constraint of the three tracks.

[0083] It can be understood that the direction of the first straight track 41 and the direction of the second track are the same as the direction of the air deflector 50 from the closed state to the first preset position.

[0084] Optionally, the sliding groove 21 is in a straight line type, and the first transmission shaft 121 slides in the sliding groove 21, thereby driving the movement of the driving slider 20. It can be understood that the direction of the sliding groove 21 can be perpendicular to the direction of the air deflector 50 from the closed state to the first preset position, or there can be a preset angle, and the direction of the sliding groove 21 is not limited in the present application.

[0085] Optionally, the diameter of the circle formed by the movement of the first transmission shaft 121 of the rocker 10 is less than or equal to the length of the sliding groove 21. In this way, the first transmission shaft 121 of the rocker 10 can be rotated by 90° in the first direction or the second direction from the initial position, and then continue to rotate, and the rotation angle of the first transmission shaft 121 is not limited by the length of the sliding groove 21.

[0086] Optionally, the rocker 10 is further provided with a second transmission shaft 122, and the driving slider 20 is further provided with a limiting slot 23, and the second transmission shaft 122 is slidingly arranged in the limiting slot 23; the second transmission shaft 122 slides in the limiting slot 23 to provide driving force for the motion of the driving slider 20.

[0087] Optionally, the limiting slot 23 is in the shape of an expanded bell, and the inner edge of the limiting slot 23 comprises a first expanded section 231, a U-shaped section 233 and a second expanded section 232 connected in sequence, and the first expanded section 231 and the second expanded section 232 are located on both sides of the U-shaped section 233. Optionally, the first expanded section 231 is provided with a first limiting point abutting against the second transmission shaft 122, and the second expanded section 232 is provided with a second limiting point abutting against the second transmission shaft 122. In the embodiment of the present disclosure, the first limiting point is represented by A, and the second limiting point is represented by B. Figure 9

[0088] The first transmission shaft 121 of the rocker 10 moves in the sliding groove 21 of the driving slider 20 to provide driving force for the motion of the driving slider 20, and the second transmission shaft 122 of the rocker moves in the limiting slot 23. It can be understood that at the first limiting point A and the second limiting point B, the second transmission shaft 122 starts to abut against the inner edge of the limiting slot 23, so that the driving slider 20 can move along the preset track against gravity. Through the abutment force between the second transmission shaft 122 and the first limiting point A or the second limiting point B, driving force is provided for the first sliding column 25 of the driving slider 20 to select the first branch track 42 or the second branch track 43 to move.

The second transmission shaft 122 is arranged on the rotation surface of the rotation rod 12 and is located between the first end of the rotation rod 12 and the first transmission shaft 121. The second transmission shaft 122 can provide the active slider 20 with driving force for selecting the track.

[0093] The driving mechanism for the air deflector 50 provided by the embodiments of the present disclosure drives the air deflector 50 to move in the following manner:

[0094] The initial state of the movement assembly of the air deflector 50 in the closed state is shown in Figure 2 When the rocker 10 is rotated in the first direction or the second direction from the initial position shown in Figure 2 , the first transmission shaft 121 slides in the sliding groove 21 of the active slider 20 to drive the active slider 20 and the driven slider 30 to move. The active slider 20 moves linearly along the straight line segment of the first linear track 41, the driven slider 30 moves linearly along the second track, and the air deflector 50 moves linearly to the first preset position. The first preset position can be understood as the position of the air deflector 50 corresponding to the movement of the first sliding column 25 of the active slider 20 to the end of the straight line segment. In the embodiments of the present disclosure, the first direction is the clockwise direction, and the second direction is the counterclockwise direction.

[0095] When the rocker 10 is rotated in the first direction, the second transmission shaft 122 of the rocker 10 moves to the first limit point A when the air deflector 50 reaches the first preset position. Because there is an abutting force between the second transmission shaft 122 and the first limit point A, the first sliding column 25 of the active slider 20 is provided with driving force for selecting the track, so that the first sliding column 25 of the active slider 20 enters the first branch track 42 from the first linear track 41, the second sliding column 26 of the active slider 20 passes through the through sliding channel 35 of the driven slider 30 and continues to move in the second linear track 44, and the active slider 20 changes direction. At the same time, the driven slider 30 continues to move linearly along the second track, so that the air deflector 50 is opened upward under the joint driving of the active slider 20 and the driven slider 30, as shown in Figure 14 .

[0096] When the rocker 10 rotates along the second direction, when the deflector 50 reaches the first preset position, the second transmission shaft 122 of the rocker 10 moves to the second limit point B, and since there is an abutting force between the second transmission shaft 122 and the second limit point B, the first sliding column 25 of the driving slider 20 is provided with a driving force for selecting the track, so that the first sliding column 25 of the driving slider 20 enters the second branch track 43 from the first straight track 41, the second sliding column 26 of the driving slider 20 continues to move in the second straight track 44 through the through sliding channel 35 of the driven slider 30, and the driving slider 20 changes the direction of movement. At the same time, the driven slider 30 continues to move linearly along the second track, so that the deflector 50 is opened downward under the joint driving of the driving slider 20 and the driven slider 30, as shown in Figure 15

[0097] It can be understood that, Figure 2 , Figures 13 to 15 are to show the movement state of the driving mechanism under different opening states of the deflector, and the spring sheet is not shown.
