[0040] Next, reference is made to Figures 1-7 Describe an air conditioner indoor unit 100 according to an embodiment of the present invention.

[0041] As Figures 1-7 shown, the air conditioner indoor unit 100 according to an embodiment of the present invention includes: a chassis 10, a guide vane support 20, a plurality of guide vanes 30, a connecting rod 40 and a driving assembly 50.

[0042] The guide vane support 20 is provided on the chassis 10 and extends along the length direction of the chassis 10. The guide vane support 20 has a plurality of mounting holes 21 arranged at intervals along its length direction. The plurality of guide vanes 30 are respectively arranged at the plurality of mounting holes 21 and can swing around the center line of the corresponding mounting hole 21. Each guide vane 30 has a rocker arm 31. The connecting rod 40 is movably provided on the guide vane support 20 and is rotatably connected to the rocker arm 31 of each guide vane 30, that is, each guide vane 30 is rotatably provided on the guide vane support 20 and is rotatably connected to the connecting rod 40 through the rocker arm 31. The driving assembly 50 is connected to the side of the guide vane support 20 facing away from the chassis 10 and drives the plurality of guide vanes 30 to swing by driving the connecting rod 40 to move.

[0043] The air conditioner indoor unit 100 according to an embodiment of the present invention has a guide vane support provided on the chassis, and the drive assembly is connected to the guide vane support, so that the drive assembly drives the connecting rod to move on one side of the guide vane support, thereby driving a plurality of guide vanes to swing. The drive assembly is reasonably arranged, the connecting rod moves smoothly, which is beneficial to improving the use reliability of the air conditioner indoor unit.

[0044] As Figures 2-4 shown, according to an embodiment of the present invention, a plurality of guide vanes 30 are provided on one side of the guide vane support 20 (such as Figure 2 the upper side of the guide vane support 20 shown), the connecting rod 40 and the drive assembly 50 are respectively provided on the side of the guide vane support 20 facing away from the guide vanes 30 (such as Figure 2 the lower side of the guide vane support 20 shown).

[0045] In some examples, each guide vane 30 is composed of a pivot part, a blade and a rocker arm 31. The blade and the rocker arm 31 are provided on opposite sides of the pivot part, that is, the blade and the rocker arm 31 extend in opposite directions, and the pivot part is swingably provided in the mounting hole 21 of the guide vane support 20. The blade of each guide vane 30 is located on one side of the guide vane support 20, and the rocker arm 31 of each guide vane 30 is located on the other side of the guide vane support 20.

[0046] As Figures 4-6 shown, according to an embodiment of the present invention, a slideway 41 is provided on the connecting rod 40. The drive assembly 50 includes a drive member 51 and a crank 52 connected to the output shaft 511 of the drive member 51. One end of the crank 52 is provided with a slider 5221 that can slide in the slideway 41. That is to say, the drive member 51, the crank 52 of the drive assembly 50 and the slideway 41 of the connecting rod 40 form a crank 52 connecting rod mechanism, and the drive member 51 is arranged adjacent to the slideway 41 of the connecting rod 40.

[0047] During operation, the drive member 51 drives the crank 52 to rotate around the central axis of the output shaft 511 of the drive member 51. Since the slider 5221 on the crank 52 cooperates with the slideway 41 of the connecting rod 40, the drive member 51 drives the connecting rod 40 to reciprocate. When the connecting rod 40 moves, it drives the rocker arm 31 to rotate, thereby achieving the purpose of driving the guide vane 30 to swing.

[0048] Therefore, compared with the technical solution in the related art in which the drive member and the crank are connected to the side of the guide vane connecting rod, by arranging the drive member 51 and the crank 52 adjacent to the slideway 41, the crank 52 and the slideway 41 of the connecting rod 40 can be assembled according to the conventional arrangement method, solving the problem in the related art that the crank connecting rod mechanism cannot be well arranged due to the structural space limitation of the air conditioner indoor unit. The drive assembly 50 of the air conditioner indoor unit in the embodiment of the present invention is reasonably arranged, so that the movement and power can be well transmitted, the use reliability is high, and the assembly is relatively easy.

[0049] As shown Figure 5 in the figure, in some examples, the air guide vane support 20 is provided with a mounting groove 22 for mounting the crank 52, and the mounting groove 22 is arranged adjacent to the slideway 41. One end of the crank 52 is rotatably mounted in the mounting groove 22 and the other end of the crank 52 is engaged in the slideway 41 through the slider 5221.

[0050] In some examples, the connecting rod 40 is formed in a rod shape extending along the arrangement direction of a plurality of air guide vanes 30 (such as Figure 5 the direction shown by n-n in the figure), and the length direction of the slideway 41 (such as Figure 5 the direction shown by m-m in the figure) is not parallel to the extending direction of the connecting rod 40.

[0051] In some specific examples, one side of the connecting rod 40 is provided with a mounting plate, and the slideway 41 penetrating along its thickness direction is arranged on the mounting plate. The length direction of the slideway 41 is perpendicular to the extending direction of the connecting rod 40.

[0052] According to an embodiment of the present invention, a limiting portion 23 is provided at each position adjacent to the mounting hole 21 of the air guide vane support 20, and the rocker arm 31 swings within the region between the limiting portion 23 and the mounting hole 21.

[0053] In some examples, the limiting portion 23 forms an arc-shaped limiting rail centered on the center of the mounting hole 21. A fan-shaped region is defined between the arc-shaped limiting rail and the mounting hole 21. The rocker arm 31 swings within the fan-shaped region driven by the connecting rod 40, so as to drive the air guide vane 30 to swing around the center of the mounting hole 21.

[0054] As Figure 6 shown in the figure, in some examples, the crank 52 includes: an annular connecting portion 521 and a crank portion 522. The connecting portion 521 is sleeved on the output shaft 511 and connected to the output shaft 511. The annular connecting portion 521 is rotatably arranged in the mounting groove 22 of the air guide vane support 20. One end of the crank portion 522 is connected to the side wall of the connecting portion 521, and the other end of the crank portion 522 is provided with a slider 5221. The structure is simple, compact, and the connection is reliable.

[0055] According to a further embodiment of the present invention, the driving assembly 50 further includes a shaft sleeve 53. The shaft sleeve 53 is sleeved on the output shaft 511 and is located between the crank 52 and the output shaft 511. The crank 52, the shaft sleeve 53 and the output shaft 511 rotate synchronously.

[0056] In some examples, the driving member 51 is a motor. The cross-sectional shape of the output shaft 511 of the motor is rectangular. Correspondingly, a rectangular groove matching with the output shaft 511 is arranged in the shaft sleeve 53, so as to ensure the fixed connection between the shaft sleeve 53 and the output shaft 511 and enable the output shaft 511 and the shaft sleeve 53 to rotate synchronously.

[0057] Similarly, the outer contour shape of the bushing 53 forms a polygon, and a polygonal groove matching with the outer side wall of the bushing 53 is arranged inside the crank 52, so as to ensure the fixed connection between the bushing 53 and the crank 52, and enable the crank 52 and the bushing 53 to rotate synchronously.

[0058] Figures 2-4 An example in which the air guide vane support 20, the connecting rod 40, and the driving assembly 50 each include two is shown. The two air guide vane supports 20 both extend along the length direction of the chassis 10, and the two air guide vane supports 20 are arranged along the length direction of the chassis 10. For example, one of the two air guide vane supports 20 is arranged on the left side of the bottom of the chassis 10, and the other of the two air guide vane supports 20 is arranged on the right side of the bottom of the chassis 10. The two connecting rods 40 and the two driving assemblies 50 are respectively arranged on the air guide vane supports 20 in one-to-one correspondence, that is, the two driving assemblies 50 respectively drive the connecting rods 40 at corresponding positions to move, so as to drive a plurality of air guide vanes 30 on the corresponding air guide vane supports 20 to swing.

[0059] It should be noted here that the two driving assemblies 50 can drive the air guide vanes 30 on the corresponding air guide vane supports 20 to rotate synchronously, and the air guide vanes 30 on the two air guide vane supports 20 can swing in the same direction, in different directions, swing simultaneously, or swing at different times, which can be understood by those skilled in the art and can be specifically set according to needs.

[0060] Of course, the number of the air guide vane supports 20, the connecting rods 40, and the driving assemblies 50 is not limited to one or two, and can also be three or more.

[0061] The air conditioner according to the second aspect embodiment of the present invention includes the air conditioner indoor unit 100 described in the above embodiment. Since the air conditioner indoor unit 100 according to the embodiment of the present invention has the above technical effects, therefore, the air conditioner according to the embodiment of the present invention also has the above technical effects, that is, the structure of the air conditioner is simple and compact, the connection of each component is reliable, the layout is reasonable, and the use reliability is high.

[0062] Next, taking a wall-mounted air conditioner as an example, a specific embodiment of the air conditioner according to the embodiment of the present invention will be described.

[0063] As Figures 1-7 shown, the wall-mounted air conditioner includes an air conditioner indoor unit 100 and an air conditioner outdoor unit. The air conditioner indoor unit 100 includes a chassis 10, two air guide vane supports 20, two connecting rods 40, two driving assemblies 50, and a plurality of air guide vanes 30.

[0064] Two air guide vane supports 20 extend along the length direction of the chassis 10 and are arranged along the length direction of the chassis 10. A plurality of spaced air guide vanes 30 are provided on one side of each air guide vane support 20. A connecting rod 40 that can move thereon is provided on the other side of each air guide vane support 20. And each connecting rod 40 is rotatably connected to a plurality of air guide vanes 30 on the air guide vane support 20 at the corresponding position. A driving assembly 50 is provided in the middle of each air guide vane support 20 (excluding the positions at the ends of the air guide vane support 20) for driving the connecting rod 40 to move, so as to drive the air guide vane 30 to swing.

[0065] Each driving assembly 50 includes a driving member 51, a sleeve 53 sleeved on the output shaft 511 of the driving member 51, and a crank 52 sleeved on the sleeve 53. The output shaft 511 rotates synchronously with the sleeve 53 and the crank 52. A slideway 41 is provided on each connecting rod 40. Correspondingly, one end of the crank 52 is provided with a slider 5221 that cooperates with the slideway 41.

[0066] During operation, the driving member 51 drives the crank 52 to rotate around the central axis of the output shaft 511 of the driving member 51. Since the slider 5221 on the crank 52 cooperates with the slideway 41 of the connecting rod 40, the driving member 51 is thus enabled to drive the connecting rod 40 to reciprocate. When the connecting rod 40 moves, it drives the rocker arm 31 to rotate, so as to achieve the purpose of driving the air guide vane 30 to swing.
