The embodiment of the disclosure provides an air conditioner and an air conditioner indoor unit.

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.

In some embodiments, the air conditioning indoor unit includes a driving mechanism for the air deflector 50 described below.

Optionally, two driving mechanisms are respectively disposed on two sides of the air guiding plate 50, and the driving mechanisms on the two sides drive the air guiding plate 50 to move simultaneously. The following driving mechanism can drive the air guiding plate 50 to extend out of the air outlet to a first preset position, and then drive the air guiding plate 50 to rotate. The structure and operation of the drive mechanism are described in detail below.

The embodiment of the disclosure also provides a driving mechanism of the air conditioner air deflector, as shown in fig. 1 to 15.

Fig. 2 and 4 show the position of the first transmission shaft of the rocker in the chute when the air deflector closes the air outlet, which may 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 guide plate 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. 4, 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. 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 toward the deformation space to push the driving slider 20 to move upward. As shown in fig. 6 to 8.

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 raised section 283 is flat or curved.

Optionally, the spring plate 28 further comprises a first abutment guide section 284 and a second abutment guide section 285. First butt guide section 284 is disposed between first connection end 281 and protruding section 283, and second butt guide section 285 is disposed between second connection end 282 and protruding section 283, wherein, the distance of first butt guide section 284 and second butt guide section 285 to the top edge is all less than the distance of protruding section 283 to the top edge.

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. 5 and 6.

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. The rocking bar 10 provides a driving force for the driving slider 20 to move through the sliding of the first transmission shaft 121 in the sliding slot 21. One end of each of the driving slider 20 and the driven slider 30 is connected to the air deflector 50, and then the driving force is transmitted to the driven slider 30 through the connecting point of the air deflector 50 and the driven slider 30, so as to drive the driven slider 30 to move. The driving slider 20 and the driven slider 30 drive the air guiding plate 50 to extend out of the air outlet to a first preset position under the limitation of the track plate 40, and then drive the air guiding plate 50 to rotate. Therefore, the rocker 10 can drive the sliding block assembly to move, and further drive the air deflector 50 to extend out of the air outlet and rotate to guide air. The driving mechanism has close matching relation and simple structure. Meanwhile, the air deflector 50 extends out of the air conditioner and rotates to conduct air at a large angle, and the air supply range of the air conditioner is expanded.

Optionally, the driving slider 20 and the driven slider 30 are both rotatably connected to the air deflector 50. Alternatively, one end of the driving 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.

In the disclosed embodiment, the first sliding column 25 of the active slider 20 moves in a first track, and the second sliding column 26 of the active slider 20 moves in a second track. When the first sliding column 25 moves from the first linear track 41 to the first branch track 42 or the second branch track 43, the driving slider 20 and the driven slider 30 will move relatively, and the movement of the driving slider 20 is redirected.

Wherein the third sliding column 31 moves in the second linear track 44, the fourth sliding column 32 moves in the third linear track 45, and the fifth sliding column 33 moves in the fourth linear track 46. That is, the follower slider 30 moves linearly under the constraint of three tracks.

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:

the initial state of the moving assembly with the air deflector 50 in the closed state is shown in figure 2. When the rocking lever 10 is rotated in the first direction or the second direction from the initial position shown in fig. 2, the first transmission shaft 121 slides in the slide groove 21 of the driving slider 20 to move the driving slider 20 and the driven slider 30. The driving slider 20 moves linearly along the straight line of the first linear track 41, and the driven slider 30 moves linearly along the second linear track, so as to drive the air deflector 50 to move linearly to the first preset position. The first predetermined position can be understood as the position of the air deflector 50 corresponding to the first sliding column 25 of the active sliding block 20 moving to the end of the straight line segment. In the embodiment of the present disclosure, the first direction is a clockwise direction, and the second direction is a counterclockwise direction.

When the rocker 10 rotates in the first direction, when the air deflector 50 reaches the first preset position, the second transmission shaft 122 of the rocker 10 moves to the first limit point a, and due to the existence of the abutting force between the second transmission shaft 122 and the first limit point a, the first sliding column 25 of the driving slider 20 is provided with the driving force for selecting the track, so that the first sliding column 25 of the driving slider 20 enters the first branch track 42 from the first linear track 41, the second sliding column 26 of the driving slider 20 passes through the through slide 35 of the driven slider 30 to continue to move in the second linear track 44, and the driving slider 20 changes the direction of motion. Meanwhile, the follower slider 30 continues to move linearly along the second track, so that the air deflector 50 is driven by the driving slider 20 and the follower slider 30 to open upwards, as shown in fig. 14.

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 due to the existence of the 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 the 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 linear track 41, the second sliding column 26 of the driving slider 20 passes through the through slide 35 of the driven slider 30 to continue to move in the second linear track 44, and the driving slider 20 changes the direction of motion. Meanwhile, the follower slider 30 continues to move linearly along the second track, so that the air deflector 50 is opened downward by the cooperation of the driving slider 20 and the follower slider 30, as shown in fig. 15.

It should be understood that fig. 2, 13 to 15 are for illustrating the motion state of the driving mechanism under different opening states of the air deflector, and the elastic sheet is not shown.
