The embodiment of the disclosure provides a rocker-slider reversing air conditioner and an air conditioner indoor unit of the air conditioner. The rocker sliding block is a rocker and a sliding block which are included in a driving mechanism for driving an air deflector of an air conditioner indoor unit to rotate, and the air deflector can be driven by the driving mechanism to supply air upwards or downwards in a reversing mode.

Optionally, the air conditioning indoor unit is a large guide plate type air conditioning indoor unit. In the air supply process of the indoor unit of the air conditioner, the air deflector 50 firstly extends out of an air outlet of the indoor unit of the air conditioner and then rotates to guide air. Thus, the air deflector 50 is far away from the air outlet, the wind resistance of the airflow blown out from the air conditioner is small, and the noise generated at the air deflector 50 in the air supply process can be reduced. Meanwhile, compared with the air supply by rotating the air deflector 50 at the air outlet, the air deflector 50 can supply air at a larger angle and in a larger range by rotating outside the air outlet, so that the refrigerating or heating effect of the air conditioner is improved. Optionally, the indoor unit of an air conditioner provided in the embodiment of the present disclosure may also be a cabinet air conditioner or an air duct machine.

The embodiment of the present disclosure provides an air deflector, as shown in fig. 1 to 3.

The air deflector 50 provided by the embodiment of the present disclosure includes an outer air deflector 51 and an inner air deflector. The outer air guide plate 51 includes an upper edge 512 that contacts an upper frame of the outlet of the indoor air conditioner and a lower edge 511 that contacts a lower frame of the outlet of the indoor air conditioner. The inner air guiding plate is disposed on the inner side surface of the outer air guiding plate 51, and the inner air guiding plate includes a first arc-shaped plate 521 with a concave air guiding surface. The first arc-shaped plate 521 extends from the lower edge 511 of the outer air guiding plate 51 to the upper edge 512.

The upper edge 512 of the outer air guide plate 51 is in contact with the upper frame of the air outlet of the air-conditioning indoor unit, and it can be understood that the upper edge 512 of the outer air guide plate 51 is in contact with the inner side wall of the upper frame, and it can also be understood that the upper edge 512 of the outer air guide plate 51 is in contact with the frame part of the upper frame. Similarly, the lower edge 511 of the outer air deflector 51 is in contact with the lower frame of the outlet of the air-conditioning indoor unit, and it is understood that the lower edge 511 of the outer air deflector 51 is in contact with the inner sidewall of the lower frame, and it is also understood that the lower edge 511 of the outer air deflector 51 is in contact with the frame portion of the lower frame. Of course, the upper edge 512 of the outer air guiding plate 51 may be substantially abutted against the upper frame, and the lower edge 511 of the outer air guiding plate 51 may be substantially abutted against the lower frame, so that the air guiding plate 50 can close the air outlet of the air conditioning indoor unit.

As shown in fig. 1 and fig. 2, the first arc-shaped plate 521 of the inner air guiding plate is connected to the lower edge 511 of the outer air guiding plate 51, and the first arc-shaped plate 521 extends from the lower edge 511 of the outer air guiding plate 51 to the upper edge 512, so that the first arc-shaped plate 521 forms an inward concave air guiding surface. Optionally, the distance between the first arc-shaped plate 521 and the inner side surface of the outer air guiding plate 51 gradually increases from the lower edge 511 of the outer air guiding plate 51 to the upper edge 512. According to the air deflector 50 provided by the embodiment of the disclosure, the inner side surface of the air deflector, which is in direct contact with the air outlet at the air outlet, is provided with the concave air guide surface, so that the effect of guiding cold air or hot air blown out from the air outlet is improved, the air loss in the air guide process is reduced, and the refrigeration or heating effect of the air conditioner is further improved. Fig. 2 is a cut-away air guiding section in fig. 1, which includes both the outer air guiding plate 51 and the inner air guiding plate.

Optionally, the outer air deflectors 51 are of a concave type. Wherein the curvature of the outer wind guide plate 51 is smaller than that of the first arc plate 521, as shown in fig. 1 and 2. Compared with the concave outer air guide plate 51, the concave air guide surface of the first arc-shaped plate 521 has larger bending degree, the guiding effect of air outlet at the air outlet is improved, the air volume loss of the air guide plate 50 in the process of upwards or downwards supplying air is reduced, and the refrigerating or heating effect of the air conditioner is further improved.

Optionally, the inner air deflection plate further comprises a second arcuate plate 522. The second arc-shaped plate 522 is disposed on the inner side surface of the outer air guiding plate 51 and has a convex air guiding surface, wherein the second arc-shaped plate 522 extends from the upper edge 512 of the outer air guiding plate 51 to the lower edge 511, and the second arc-shaped plate 522 is connected to the first arc-shaped plate 521.

The inner air deflection plate also includes a second arcuate plate 522 having a convex deflection surface. The second arc-shaped plate 522 is connected to the upper edge 512 of the outer air guiding plate 51 and extends from the upper edge 512 of the outer air guiding plate 51 to the lower edge 511. Meanwhile, the inner air deflector is provided with an outer convex air guide surface and an inner concave air guide surface, so that the outer air deflector 51 and the inner air deflector form a structure similar to a dolphin-shaped air deflector 50, the guiding effect on air outlet at an air outlet is improved, the air volume loss of the air deflector 50 in the air guide process is reduced, and the air outlet speed at the air outlet is improved. Optionally, the curvature of the first arcuate plate 521 is less than the curvature of the second arcuate plate 522. The degree of curvature of the second arc-shaped plate 522 with the convex air guide surface is greater than that of the first arc-shaped plate 521 with the concave air guide surface.

Optionally, a joint M between the first arc-shaped plate 521 and the second arc-shaped plate 522 is vertically projected to a first position N of the outer wind guide plate 51, wherein a distance from the first position N to the lower edge 511 of the outer wind guide plate 51 is 2/3-4/5 of the width of the outer wind guide plate 51, as shown in fig. 3.

The vertical projection is performed from above the air deflector 50, and the joint M between the first arc-shaped plate 521 and the second arc-shaped plate 522 is projected to the first position N of the outer air deflector 51. The distance from the upper edge 512 to the lower edge 511 of the outer air deflection panel 51 forms the width of the outer air deflection panel 51. The distance from the first position N to the lower edge 511 of the outer wind deflector 51 is 2/3-4/5 of the width of the outer wind deflector 51, that is, the first position N is closer to the upper edge 512 of the outer wind deflector 51 than to the lower edge 511 of the outer wind deflector 51, and it can also be understood that the extension length of the concave wind deflecting surface of the first arc-shaped plate 521 is longer than that of the convex wind deflecting surface of the second arc-shaped plate 522. Therefore, the guiding contact area of the concave air guide surface to the air outlet at the air outlet is increased, and the air quantity loss in the air guide process is reduced.

Optionally, a distance from a connection point M of the first arc-shaped plate 521 and the second arc-shaped plate 522 to the first position N of the outer air guiding plate 51 is greater than or equal to 15mm and less than 21 mm. The connection point M between the first arc-shaped plate 521 and the second arc-shaped plate 522 is the position where the distance between the inner wind-guiding plate and the outer wind-guiding plate 51 is the largest, as shown in fig. 3.

When the air conditioner performs heating operation and the air outlet is opened downwards, the air guide effect that the distance between the connecting part M of the first arc-shaped plate 521 and the second arc-shaped plate 522 and the first position N is 17mm and the downward opening angle of the air guide plate 50 is 100 degrees is tested, and the air quantity loss is 2.3%, and the maximum air outlet speed is 7.6M/s. Meanwhile, the air guide effect that only the outer air guide plate 51 is arranged and the air guide plate structure without the inner air guide plate is arranged and the downward opening angle of the air guide plate is 100 degrees is tested, so that the air quantity loss is 5.7%, and the maximum air outlet speed is 7.1%. Compared with an air deflector structure without an inner air deflector, the air deflector 50 structure provided by the embodiment of the disclosure including the outer air deflector 51 and the inner air deflector reduces air volume loss in an air guiding process, and simultaneously improves the maximum air outlet speed, thereby improving the cooling or heating effect of the air conditioner.

Optionally, a hollow cavity is formed between the outer air deflector 51 and the inner air deflector, so that the overall weight of the air deflector is reduced, the driving stability of the driving mechanism on the air deflector is improved, and meanwhile, the condensation prevention effect of the air deflector is improved. 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 fig. 3. Therefore, the rigidity of the whole structure of the air deflector is improved, and the deformation of the air deflector is favorably prevented.

The embodiment of the disclosure also provides a driving mechanism of the air conditioner air deflector, as shown in fig. 4 to 18.

Fig. 5 and 7 show the position of the first transmission shaft of the rocker in the chute when the air deflector closes the air outlet, which can also be referred to as the centering position of the first transmission shaft of the rocker.

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 sliding block 20 is provided with a sliding chute 21, one end of the driving sliding block 20 is rotatably connected with the air deflector 50, and the first transmission shaft 121 is slidably arranged in the sliding chute 21; one end of the driven slide block 30 is rotationally connected with the air deflector 50; a track plate 40 provided with track portions for defining a movement track 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 by the sliding of the first transmission shaft 121 in the sliding slot 21, so that the air deflector 50 extends out of the air outlet to a first preset position and then rotates.

As shown in fig. 7, when the air outlet is closed by the air deflector, the first transmission shaft 121 is located at the centering position of the chute, an elastic abutting member is disposed at the upper edge of the centering position of the chute, the first transmission shaft 121 abuts against the elastic abutting member, and the first transmission shaft 121 pushes the driving slider 20 to move upward, so that the driving slider 20 pulls the air deflector to close the air outlet.

When the air deflector is controlled to close the air outlet, the first transmission shaft 121 slides along the chute and gradually moves to the centering position of the chute. When the first transmission shaft 121 of the rocker 10 moves to the centering position of the chute, the first transmission shaft 121 abuts against the elastic abutting part, so that the first transmission shaft 121 applies an upward pushing force to the driving slider 20 to push the driving slider 20 to move upward, and the air deflector is pulled to close the air outlet in the upward movement process of the driving slider 20.

According to the driving mechanism of the air conditioner air deflector provided by the embodiment of the disclosure, in the closing process of the air deflector, the rocker 10 can generate a force for pushing the driving slider 20 to move upwards, so that the air deflector is pulled to close the air outlet, the problem that a gap exists between the air deflector and a frame at the air outlet due to manufacturing errors and installation gaps of the air deflector is solved, the closing tightness between the air deflector and the air outlet is improved, and the attractiveness of an indoor unit of an air conditioner is improved.

It should be understood that the "upward movement of the active slider 20" is not limited to a vertical upward direction, and may also be an upward inclination along the movement direction of the active slider 20, as long as the active slider 20 can pull the air deflector to close the air outlet in this direction.

Optionally, the elastic abutting member includes a protruding portion protruding toward the sliding slot, and at the centering position, the first transmission shaft 121 is in interference fit with the protruding portion, and the elastic abutting member deforms to push the driving slider 20 to move upward.

The elastic abutting connection piece is arranged in a protruding mode towards the inner portion of the sliding groove. The elastic abutting piece is provided with a protruding portion protruding towards the inside of the sliding groove, when the air outlet is closed through the air deflector, 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 deforms, meanwhile, the elastic abutting piece on the driving sliding block 20 is subjected to upward pushing force generated by extrusion, and therefore the driving sliding block 20 is pushed by the first transmission shaft 121 of the rocker 10 to move upwards.

Alternatively, the elastic abutment member may be an elastic material that is deformed by the pressing of the first transmission shaft 121 and can recover its original shape when not pressed by the first transmission shaft 121, such as a spring, an elastic sheet 28, rubber, sponge, latex, and the like.

Alternatively, the shape of the resilient abutment may be semicircular, semi-elliptical, trapezoidal, arched bridge or other irregular convex shape.

Optionally, the resilient abutment comprises a spring tab 28. The resilient tab 28 includes a first connecting end 281, a second connecting end 282, and a raised section 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 section 283 is arranged between the first connecting end 281 and the second connecting end 282. Wherein, a deformation space is provided between the protruding section 283 and the upper edge, and at the centering position, the protruding section 283 is pressed by the first transmission shaft 121 to the deformation space so as to push the driving slider 20 to move upwards. As shown in fig. 9-11.

The convex section 283 is not arranged in a solid manner to the upper edge, i.e. a deformation space is arranged between the convex 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 the pressing force is generated to drive the driving slider 20 to move upwards. Optionally, the convex section 283 is flat plate or arc.

Optionally, the spring plate 28 further comprises a first abutment guide section 284 and a second abutment guide section 285. The first abutting guiding section 284 is arranged between the first connecting end 281 and the convex section 283, and the second abutting guiding section 285 is arranged between the second connecting end 282 and the convex section 283, wherein the distance from the upper edge of each of the first abutting guiding section 284 and the second abutting guiding section 285 is smaller than the distance from the upper edge of the convex section 283.

Alternatively, the first abutting guide section 284 may be an arc or a slope 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 slide to the protruding section 283 of the striking plate 28. The second abutment guide 285 may be an arc or a slope connecting the second connection end 282 and the protrusion section 283 to guide the first transmission shaft 121 of the rocker 10 to slide along the second abutment guide 285 until being disengaged from the resilient plate 28. Wherein the distance of first abutment guide section 284, second abutment guide section 285 and convex section 283 to the upper edge may be understood as the perpendicular distance of first abutment guide section 284, second abutment guide section 285 and convex section 283 to the upper edge, respectively.

Optionally, the distance from convex segment 283 to the upper edge is less than or equal to the radius of first drive shaft 121.

The gap between the air deflector and the air outlet frame is small due to the manufacturing error of the air deflector and the assembly gap. In this regard, the distance between the convex section 283 and the upper edge does not have to be large, and may be smaller than or equal to the radius of the first transmission shaft 121. If the distance between the protruding section 283 and the upper edge is too large, the normal sliding of the first transmission shaft 121 of the rocker 10 along the sliding slot is also affected.

Optionally, the lower edge at the centered position of the chute is provided with an avoidance groove 29 avoiding the first transmission shaft 121. As shown in fig. 8 and 9.

When the first transmission shaft 121 is in contact with the elastic contact member, the first transmission shaft 121 is also slightly moved downward relative thereto. An avoidance groove 29 that avoids the downward movement of the first transmission shaft 121 is provided at the lower edge of the chute at the centering position, providing a space for the downward movement of the first transmission shaft 121. Alternatively, the downward movement of the first drive shaft 121 is limited, and the vertical distance from the escape recess 29 to the lower edge does not have to be too large, and may be less than or equal to the radius of the first drive shaft 121.

The following embodiments are provided to describe the structure of the rocker, the driving slider, the driven slider, the track plate, etc. in the driving mechanism of the air deflector of the air conditioner, and the rotation process of the driving mechanism driving the air deflector.

Alternatively, the driving force for the movement of the active slider 20 comes from the rocker 10.
