[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 embodiments of the present disclosure provide a rocker slider reversing air conditioner and an air conditioner indoor unit of the air conditioner. Wherein, the rocker slider is a rocker and a slider included in a driving mechanism for driving the rotation of the air conditioner indoor unit air deflector, and the reversing is that the driving mechanism can drive the air deflector to perform upward air supply or downward air supply.

[0050] Optionally, the air conditioner indoor unit is a large guide vane type air conditioner indoor unit. In the air supply process, the guide vane 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 guide vane 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 guide vane 50 during the air supply process. At the same time, compared with the rotation of the guide vane 50 at the air outlet for air supply, the rotation of the guide vane 50 outside the air outlet can perform air supply in a larger angle and a larger range, thereby improving the refrigeration or heating effect of the air conditioner. Optionally, the air conditioner indoor unit provided by the embodiment of the present disclosure can also be a cabinet type air conditioner or a duct type air conditioner.

[0051] The embodiment of the present disclosure provides a guide vane, as shown in Figures 1 to 3

[0052] The guide vane provided by the embodiment of the present disclosure comprises an outer guide vane and an inner guide vane. The outer guide vane comprises a first end mounting section 501, a second end mounting section 502, and a guide section 503 arranged between the first end mounting section 501 and the second end mounting section 502. The outer guide vane comprises an upper edge 512 abutting against an upper frame of an air outlet of an air conditioner indoor unit and a lower edge 511 abutting against a lower frame of the air outlet. The inner guide vane is arranged on the inner side of the guide section 503, and the inner guide vane comprises a first arc-shaped plate 521 having an inner concave air guide surface and a second arc-shaped plate 522 having an outer convex air guide surface. The first arc-shaped plate 521 extends from the lower edge 511 to the upper edge 512 of the outer guide vane, the second arc-shaped plate 522 extends from the upper edge 512 to the lower edge 511 of the outer guide vane, and the second arc-shaped plate 522 is connected with the first arc-shaped plate 512.

[0053] The upper edge 512 of the outer guide vane abuts against the upper frame of the air outlet of the air conditioner indoor unit, which can be understood as that the upper edge 512 of the outer guide vane abuts against the inner side wall of the upper frame, or that the upper edge 512 of the outer guide vane abuts against the frame part of the upper frame. Similarly, the lower edge 511 of the outer guide vane abuts against the lower frame of the air outlet of the air conditioner indoor unit, which can be understood as that the lower edge 511 of the outer guide vane abuts against the inner side wall of the lower frame, or that the lower edge 511 of the outer guide vane abuts against the frame part of the lower frame. Of course, it can also be understood that the upper edge 512 of the outer guide vane abuts against the upper frame, and the lower edge 511 of the outer guide vane abuts against the lower frame, so that the guide vane 50 can close the air outlet of the air conditioner indoor unit.

[0054] As shown in Figure 1 and Figure 2 ​As shown, the first arc-shaped plate 521 of the inner air guide plate is connected with the lower edge 511 of the outer air guide plate 51, and the first arc-shaped plate 521 is arranged to extend from the lower edge 511 to the upper edge 512 of the outer air guide plate 51, so that the first arc-shaped plate 521 forms a concave air guide surface. Alternatively, the distance between the first arc-shaped plate 521 and the inner side surface of the outer air guide plate 51 gradually increases from the lower edge 511 to the upper edge 512 of the outer air guide plate 51. Wherein, Figure 2 is intercepted Figure 1 A structural schematic diagram of the air guide section provided with the inner air guide plate.

[0055] The inner air guide plate further includes a second arc-shaped plate 522 having an outer convex air guide surface. The second arc-shaped plate 522 is connected with the upper edge 512 of the outer air guide plate, and is arranged to extend from the upper edge 512 to the lower edge 511 of the outer air guide plate. The inner air guide plate having the outer convex air guide surface and the concave air guide surface makes the outer air guide plate and the inner air guide plate form a structure similar to a dolphin-shaped air guide plate 50, improves the guiding effect of the air outlet, reduces the air volume loss of the air guide plate 50 in the air guiding process, and improves the air outlet speed at the air outlet. Alternatively, the curvature of the first arc-shaped plate 521 is smaller than the curvature of the second arc-shaped plate 522. The bending degree of the second arc-shaped plate 522 having the outer convex air guide surface is greater than the bending degree of the first arc-shaped plate 521 having the concave air guide surface.

[0056] Alternatively, the ratio of the length of the inner air guide plate to the length of the outer air guide plate is greater than or equal to 2 / 3 and less than 1. In this way, the first end portion mounting section 501 for arranging the first mounting seat 551 and the second end portion mounting section 502 for arranging the second mounting seat 552 can be reserved. Moreover, the length of the inner air guide plate can be made longer to improve the air guiding effect of the air guide plate and reduce the air volume loss in the air guiding process. It can be understood that the length of the outer air guide plate is the distance from the first air blocking folded edge to the second air blocking folded edge.

[0057] Alternatively, the air guide plate further includes a first mounting seat 551 and a second mounting seat 552. The first mounting seat 551 is arranged on the inner side surface of the first end portion mounting section 501, and the first mounting seat 551 is used to mount a first driving mechanism for driving the air guide plate to rotate reversely. The second mounting seat 552 is arranged on the inner side surface of the second end portion mounting section 502, and the second mounting seat 552 is used to mount a second driving mechanism for driving the air guide plate to rotate reversely. Alternatively, the first driving mechanism and the second driving mechanism are the same in structure, and both of them include a rocker, a driving slider, a driven slider, a track plate and the like, as follows.

[0058] Optionally, the air deflector further comprises a first air blocking fold 541 and a second air blocking fold 542. The first air blocking fold 541 is connected to the edge of the first end mounting section 501 by bending, and the first air blocking fold 541 is used to block the left side of the air outlet. The second air blocking fold 542 is connected to the edge of the second end mounting section 502 by bending, and the second air blocking fold 542 is used to block the right side of the air outlet. Optionally, the shapes of the first air blocking fold 541 and the second air blocking fold 542 are the same as the shape of the cross section of the inner air deflector, such as a dolphin type, as shown in Figure 1 .

[0059] Optionally, the connecting position M between the first arc-shaped plate 521 and the second arc-shaped plate 522 is vertically projected on the first position N of the outer air deflector 51, wherein the distance between the first position N and the lower edge 511 of the outer air deflector 51 is 2 / 3-4 / 5 of the width of the outer air deflector 51, as shown in Figure 3 .

[0060] Vertically projecting from above the air deflector 50, the connecting position M between the first arc-shaped plate 521 and the second arc-shaped plate 522 is projected on the first position N of the outer air deflector 51. The distance between the upper edge 512 and the lower edge 511 of the outer air deflector 51 forms the width of the outer air deflector 51. The distance between the first position N and the lower edge 511 of the outer air deflector 51 is 2 / 3-4 / 5 of the width of the outer air deflector 51, that is, the first position N is closer to the upper edge 512 of the outer air deflector 51 relative to the lower edge 511 of the outer air deflector 51, and it can also be understood that the extension length of the inner concave air deflector surface of the first arc-shaped plate 521 is longer than that of the outer convex air deflector surface of the second arc-shaped plate 522. In this way, the guiding contact area of the inner concave air deflector surface to the air outlet is increased, and the air volume loss in the air guiding process is reduced.

[0061] Optionally, the distance between the connecting position M between the first arc-shaped plate 521 and the second arc-shaped plate 522 and the first position N of the outer air deflector 51 is greater than or equal to 15 mm and less than 21 mm. The connecting position M between the first arc-shaped plate 521 and the second arc-shaped plate 522 is the position farthest from the outer air deflector 51, as shown in Figure 3 .

[0062] When the air conditioner is in heating operation and the air outlet is opened downward, the distance between the connection position M of the first arc-shaped plate 521 and the second arc-shaped plate 522 and the first position N is 17 mm, and the downward opening angle of the air deflector 50 is 100°, the air deflection effect is tested, and it is obtained that the air volume loss is 2.3%, and the maximum air outlet wind speed is 7.6 m / s. At the same time, the air deflection effect of the air deflector structure only having the outer air deflector 51 without the inner air deflector and the air deflector opening downward at an angle of 100° is tested, and it is obtained that the air volume loss is 5.7%, and the maximum air outlet wind speed is 7.1%. It can be seen from the air deflection effect that, compared with the air deflector structure without the inner air deflector, the air deflector 50 structure provided by the embodiment of the present disclosure simultaneously including the outer air deflector 51 and the inner air deflector reduces the air volume loss in the air deflection process, at the same time, improves the maximum air outlet wind speed, and further improves the refrigeration or heating effect of the air conditioner.

[0063] Optionally, the outer air deflector 51 and the inner air deflector are hollow cavities, which reduces the overall weight of the air deflector, improves the driving stability of the driving mechanism to the air deflector, and at the same time improves the anti-condensation effect of the air deflector. Wherein, a plurality of inner rib plates 53 connecting the outer air deflector 51 and the inner air deflector are arranged in the hollow cavity, as shown in Figure 3 Thus, the rigidity of the overall structure of the air deflector is improved, which is beneficial to prevent the air deflector from deforming.

[0064] The embodiment of the present disclosure also provides a driving mechanism of an air deflector of an air conditioner, as shown in Figures 4 to 18 .

[0065] Figure 5 and Figure 7 The position of the first transmission shaft of the rocker in the sliding groove when the air deflector closes the air outlet is also called the centering position of the first transmission shaft of the rocker.

[0066] In some embodiments, the driving mechanism for the air deflector 50 includes a rocker 10, a driving sliding block 20, a driven sliding block 30 and a track plate 40, the rocker 10 is provided with a first transmission shaft 121; the driving sliding block 20 is provided with a sliding groove 21, one end of the driving sliding block 20 is rotationally connected with the air deflector 50, and the first transmission shaft 121 is slidingly arranged in the sliding groove 21; one end of the driven sliding block 30 is rotationally connected with the air deflector 50; the track plate 40 is provided with a track portion for limiting the movement trajectories of the driving sliding block 20 and the driven sliding block 30; wherein the rocker 10 drives the driving sliding block 20 and the driven sliding block 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.

[0067] As shown in Figure 7As shown, when the air deflector closes the air outlet, the first transmission shaft 121 is in the centering position of the sliding groove, the upper edge of the centering 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 sliding block 20 to move upward, so that the driving sliding block 20 pulls the air deflector to close the air outlet.

[0068] 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 centering position of the sliding groove. When the first transmission shaft 121 of the rocker 10 moves to the centering position of the sliding groove, the first transmission shaft 121 abuts against the elastic abutting piece, so that the first transmission shaft 121 gives the driving sliding block 20 a force to drive it to move upward, and the driving sliding block 20 is driven to move upward, and in the process of moving upward, the driving sliding block 20 pulls the air deflector to close the air outlet.

[0069] The driving mechanism of the air deflector of the air conditioner provided by the embodiment of the present disclosure can generate a force to drive the driving sliding block 20 to move upward during the closing process of the air deflector, and then pull the air deflector to close the air outlet, thereby overcoming the problem that the air deflector and the frame at the air outlet have a gap due to the manufacturing error and the installation gap of the air deflector, improving the closing tightness of the air deflector and the air outlet, and then improving the appearance of the air conditioner indoor unit.

[0070] It can be understood that "the driving sliding block 20 moves upward" is not limited to vertical upward, but can also be inclined upward along the movement direction of the driving sliding block 20, as long as the driving sliding block 20 can pull the air deflector to close the air outlet in this direction.

[0071] Optionally, the elastic abutting piece includes a protruding part protruding into the sliding groove, and the first transmission shaft 121 is in interference fit with the protruding part at the centering position, and the elastic abutting piece is deformed to drive the driving sliding block 20 to move upward.

[0072] The elastic abutting piece protrudes into the sliding groove. The elastic abutting piece is provided with a protruding part protruding into the sliding groove, and when the air deflector closes the air outlet, the first transmission shaft 121 of the rocker 10 is in interference fit with the protruding part of the elastic abutting piece at the centering position, the elastic abutting piece is extruded by the first transmission shaft 121 and deformed, and at the same time, the elastic abutting piece on the driving sliding block 20 is extruded to generate a upward driving force, and then the first transmission shaft 121 of the rocker 10 drives the driving sliding block 20 to move upward.

[0073] Optionally, the elastic abutting piece can be an elastic material that is deformed by 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.

[0074] Optionally, the shape of the elastic abutting member can be semicircular, semi-elliptical, ladder-shaped, arch-shaped, or other irregular shapes with protrusions.

[0075] Optionally, the elastic abutting member includes an elastic sheet 28. The elastic sheet 28 includes a first connecting end 281, a second connecting end 282, and a protruding section 283. The first connecting end 281 is fixedly connected to the upper edge, the second connecting end 282 is fixedly connected to the upper edge, and the protruding section 283 is arranged between the first connecting end 281 and the second connecting end 282. A deformation space is arranged between the protruding section 283 and the upper edge. In the centering position, the protruding section 283 is pressed by the first transmission shaft 121 to the deformation space to drive the driving slider 20 to move upward. Figures 9 to 11

[0076] The protruding section 283 is not solidly arranged to the upper edge, i.e., a deformation space is arranged between the protruding section 283 and the upper edge. When the first transmission shaft 121 presses the protruding section 283 of the elastic sheet 28, the protruding section 283 deforms into the deformation space, and at the same time, generates a post-pressing force to drive the driving slider 20 to move upward. Optionally, the protruding section 283 is flat or arc-shaped.

[0077] Optionally, the elastic sheet 28 further includes a first abutting guide section 284 and a second abutting guide section 285. The first abutting guide section 284 is arranged between the first connecting end 281 and the protruding section 283, and the second abutting guide section 285 is arranged between the second connecting end 282 and the protruding section 283. The distance from the first abutting guide section 284 and the second abutting guide section 285 to the upper edge is less than the distance from the protruding section 283 to the upper edge.

[0078] Optionally, the first abutting guide section 284 can be arc-shaped or bevel-shaped to connect the first connecting end 281 and the protruding section 283, so as to guide the first transmission shaft 121 of the rocker 10 to slide along the first abutting guide section 284 and slide to the protruding section 283 of the elastic sheet 28. The second abutting guide section 285 can be arc-shaped or bevel-shaped to connect the second connecting end 282 and the protruding section 283, so as to guide the first transmission shaft 121 of the rocker 10 to slide along the second abutting guide section 285 until the elastic sheet 28 is separated.

Therefore, the distance from the convex section 283 to the upper edge does not have to be large, and can be less than or equal to the radius of the first transmission shaft 121. If the distance from the convex 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.

[0081] Optionally, the lower edge at the centering position of the sliding groove is provided with a recess 29 avoiding the first transmission shaft 121. Figure 8 and Figure 9 as shown.

[0082] 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 centering position of the sliding groove is provided with a recess 29 avoiding the downward movement of the first transmission shaft 121, which provides 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 large, and can be less than or equal to the radius of the first transmission shaft 121.

[0083] The following embodiments describe the structure of the rocker, the driving slide, the driven slide, the track plate, etc. in the driving mechanism of the air deflector of an air conditioner, and the rotation process of the driving mechanism driving the air deflector.

[0084] Optionally, the driving force for the movement of the driving slide 20 comes from the rocker 10. The rocker 10 provides the driving force for the movement of the driving slide 20 through the sliding of the first transmission shaft 121 in the sliding groove 21. One end of the driving slide 20 and the driven slide 30 is connected with the air deflector 50, and then the driving force is transmitted to the driven slide 30 through the connection point of the air deflector 50 and the driven slide 30, driving the driven slide 30 to move. The driving slide 20 and the driven slide 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 slide assembly to move, 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 extending out of the air conditioner and rotating can guide the air at a large angle, expanding the air supply range of the air conditioner.

[0092] In the embodiment of the present disclosure, the first sliding column 25 of the driven slider 20 moves in the first track, and the second sliding column 26 of the driven 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 driven slider 20 will produce relative movement with the driven slider 30, and the driven slider 20 will change the movement direction.

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 groove 23, so that the driving slider 20 can move along the preset track against gravity. The abutment force between the second transmission shaft 122 and the first limiting point A or the second limiting point B provides driving force 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.

[0100] Optionally, the rocker comprises a rotating disc 11 and a rotating rod 12, the rotating disc 11 has a rotation center, and the rotating disc 11 is provided with a notch 111; the rotating rod 12 is fixedly connected at the first end to the notch 111, and the second end of the rotating rod 12 is a free end.

The second transmission shaft 122 is arranged at the rotating surface of the rotating rod 12 and located between the first end of the rotating rod 12 and the first transmission shaft 121. The second transmission shaft 122 can provide driving force for the driving slider 20 to select a track.

[0104] The driving mechanism for the air deflector 50 provided by the embodiment of the present disclosure drives the air deflector 50 to move in the following manner:

[0105] The initial state of the movement assembly of the air deflector 50 in the closed state is shown in FIG. 2. Figure 5 When the rocker 10 is in the initial state, the first transmission shaft 121 is located at the first limiting point A, and the second transmission shaft 122 is located at the second limiting point B. Figure 5The initial position shown rotates in the first direction or the second direction, the first transmission shaft 121 slides in the sliding groove 21 of the driving slider 20 to drive the driving slider 20 and the driven slider 30 to move. Among them, the driving 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 in turn drives the air deflector 50 to move 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 driving slider 20 to the end of the straight line segment.

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 driving slider 20 and the driven slider 30, as shown in Figure 17 .

[0107] When the rocker 10 rotates in the second direction, when the air deflector 50 reaches the first preset position, the second transmission shaft 122 of the rocker 10 moves to the second limit point B, and because there is an abutting force between the second transmission shaft 122 and the second limit point B, the driving force of the selected track is provided for the first sliding column 25 of the driving slider 20, so that the first sliding column 25 of the driving slider 20 enters the second branch track 43 from the first linear track 41, the second sliding column 26 of the driving 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 driving slider 20 changes direction.
