Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and in particular to a louvered assembly and an air conditioner. Background Technology

[0002] During operation, air conditioning equipment typically draws in indoor air, cools it down, and then blows it out. The air blown out during this process is at a low temperature and is not suitable for blowing directly on people. Therefore, air conditioning equipment with a gentle breeze function has emerged, which uses a porous structure to disperse the air and blow out a gentle breeze.

[0003] Furthermore, the related technology integrates a porous structure onto the left and right sweeping blades. When the left and right sweeping blades are perpendicular to the airflow direction, the airflow passes through the porous structure, achieving a gentle breeze effect. However, when the left and right sweeping blades intersect with the airflow direction, the airflow will be guided to the left or right by the blades, and the gentle breeze effect will be lost.

[0004] Therefore, the gentle breeze effect is only achieved when the left and right sweeping blades are perpendicular to the air outlet direction, resulting in a relatively limited air outlet effect for the air conditioning equipment. Utility Model Content

[0005] This application provides a louver assembly and an air conditioner that can solve the problem of the relatively simple air output effect of air conditioning equipment.

[0006] The technical solution is as follows:

[0007] On one hand, a sway blade assembly is provided, the sway blade assembly comprising: a sway blade element;

[0008] The oscillating blade component is provided with a gentle airflow hole and a windproof protrusion;

[0009] The soft wind hole is arranged through the thickness direction of the blade, and the windproof protrusion is located close to the soft wind hole and on one side of the soft wind hole. The windproof protrusion is used to enhance the soft wind generated by the soft wind hole.

[0010] The oscillating blade assembly of this application is disposed at the air outlet. The oscillating blade in the oscillating blade assembly has a gentle airflow hole and a wind-blocking protrusion. When the oscillating blade is arranged at an angle to the airflow direction, the wind-blocking protrusion faces away from the airflow and is located on the leeward side of the gentle airflow hole, a portion of the airflow blowing out of the air outlet directly into the gentle airflow hole can directly enter the gentle airflow hole. The other portion of the airflow facing the oscillating blade is guided into the gentle airflow hole by the wind-blocking protrusion as it flows with the oscillating blade. Thus, a gentle airflow effect can be achieved without keeping the oscillating blade perpendicular to the airflow direction. Moreover, since there is a certain angle between the gentle airflow hole and the airflow direction, the gentle airflow blown out of the gentle airflow hole also has a certain directionality, which can achieve gentle airflow delivery to specific areas on the left and right sides.

[0011] In some possible implementations, when the air outlet and the louver are tilted opposite each other and the windproof protrusion is opposite to the airflow, the windproof protrusion is located on the leeward side of the soft air hole.

[0012] With the above arrangement, the windproof protrusion can guide the airflow flowing along the surface of the oscillating blade into the soft wind hole, thereby improving the soft wind effect of the oscillating blade.

[0013] In some possible implementations, the height of the windproof protrusion is h, and the diameter of the soft air hole is D, where the value of h / D is 0.2-0.8.

[0014] When the height h of the windshield protrusion and the diameter D of the wind-softening hole meet the above-mentioned value range, the oscillating blade not only has good wind guiding performance, but also good wind-softening performance.

[0015] In some possible implementations, the windproof protrusion is fitted to the edge of the soft air hole, or the windproof protrusion is spaced apart from the edge of the soft air hole.

[0016] With the above arrangement, the windshield protrusions and the air vents can be arranged close together or spaced apart, providing greater flexibility.

[0017] In some possible implementations, the windproof protrusion is arranged in an arc shape around the edge of the soft air hole.

[0018] With the above arrangement, the windshield protrusion is constructed in an arc shape and is arranged around the edge of the soft air hole, so that the windshield protrusion can guide the airflow into the soft air hole in a certain range of circumferential directions.

[0019] In some possible implementations, the central angle of the windproof protrusion around the axis of the wind-reducing hole ranges from 120 to 240 degrees.

[0020] When the value of the central angle of the windshield protrusion around the wind deflector hole meets the above range, the windshield protrusion has a better wind-blocking effect.

[0021] In some possible implementations, multiple soft air holes are provided, and the multiple soft air holes are arranged at intervals on the oscillating blade. The windproof protrusion is provided on one side of some or all of the soft air holes.

[0022] With the above arrangement, multiple soft air holes are arranged on the oscillating blades, which has a better soft air effect. Moreover, it is only necessary to arrange a windproof protrusion on one side of some of the soft air holes to guide some of the airflow into the soft air holes, thereby improving the soft air effect of the oscillating blades.

[0023] In some possible implementations, the projections of two adjacent windshield protrusions arranged along the rotation axis of the blade overlap in the air outlet direction.

[0024] With the above arrangement, two adjacent windproof protrusions can form a continuous windproof effect in the direction of the rotation axis, thereby guiding the overall airflow to the soft wind hole, resulting in a better soft wind effect.

[0025] In some possible implementations, wind-blocking protrusions are provided at both ends of the flexible air hole along the axial direction, located on the same side of the flexible air hole axis.

[0026] With the above arrangement, the two ends of the soft air hole have windproof protrusions, so that no matter which side of the oscillating blade faces the air outlet direction, the windproof protrusions can guide the airflow into the soft air hole, ensuring the double-sided soft air performance of the oscillating blade.

[0027] In some possible implementations, the porosity of the flap element ranges from 5% to 50%.

[0028] When the porosity of the oscillating blade meets the above-mentioned range, the oscillating blade has a good wind-softening effect.

[0029] In some possible implementations, the inner diameter of the soft air hole is at least partially different from the inner diameter of the end.

[0030] With the above arrangement, the soft air vents have a variety of structural features, which can meet different soft air needs.

[0031] In some possible implementations, the blade assembly further includes a mounting plate on which the blade is rotatably connected.

[0032] With the above arrangement, the louvered blades can be rotated and supported by the mounting plate, so that they can be installed on air conditioners or other air outlet equipment to achieve the functions of guiding and softening air.

[0033] In some possible implementations, multiple oscillating blades are provided, and the multiple oscillating blades are arranged at intervals on the mounting plate along the extension direction of the mounting plate, and some or all of the oscillating blades are provided with the windproof protrusions.

[0034] With the above arrangement, the oscillating blade assembly has multiple oscillating blades, and they are installed sequentially at intervals using a mounting plate. Thus, the oscillating blade assembly can achieve wind guiding and wind softening functions within the extended space of the mounting plate. Furthermore, some or all of the oscillating blades are provided with wind-blocking protrusions, which makes the oscillating blade assembly have better wind guiding and wind softening effects.

[0035] In some possible implementations, the plurality of the sway blades are divided into a first region, a second region and a third region along the extension direction of the mounting plate, with the first region and the third region respectively close to both ends of the mounting plate, and the second region located between the first region and the third region;

[0036] The windproof protrusion is provided only on the oscillating blade in the first region, or only on the oscillating blade in the second region, or only on the oscillating blade in the third region, or only on the oscillating blade in both the first region and the third region.

[0037] Alternatively, of the two adjacent sway blades, only one of the sway blades is provided with the windproof protrusion.

[0038] With the above arrangement, the multiple oscillating blades are divided into three areas. The oscillating blades in each area can be selectively equipped with or without windproof protrusions. This is to take into account that the oscillating blades in different areas have different requirements for air guidance and wind softening. Windproof protrusions are arranged on the oscillating blades in areas with higher requirements for wind softening, while windproof protrusions are not required on the oscillating blades in areas with lower requirements for wind softening.

[0039] In some possible implementations, the oscillating blade assembly further includes a connecting rod, which is movably disposed relative to the mounting plate, and a plurality of oscillating blades are rotatably connected to the connecting rod, with the connecting rod driving the plurality of oscillating blades to rotate.

[0040] With the above arrangement, the oscillating blades can be driven by the connecting rod to achieve synchronous rotation, thus achieving synchronous airflow or gentle airflow effects.

[0041] In some possible implementations, the leaf assembly further includes a drive assembly;

[0042] The drive assembly is connected to one of the oscillating blades, and the drive assembly is used to drive the oscillating blade to rotate. The oscillating blade drives the other oscillating blades to rotate through the connecting rod.

[0043] In this embodiment, the drive component drives one oscillating blade to rotate, which in turn drives a connecting rod to move, and finally the connecting rod drives the remaining oscillating blades to rotate, thus achieving the driving effect of a single drive component driving all the oscillating blades to rotate.

[0044] In some possible implementations, the leaf assembly further includes a drive assembly;

[0045] The drive assembly is connected to the connecting rod, and the drive assembly is used to drive the connecting rod to move, and the connecting rod drives the plurality of the oscillating blades to rotate.

[0046] In this embodiment, the drive component moves through a connecting rod, which can drive all the oscillating blades to rotate, thus achieving the driving effect of a single drive component driving all the oscillating blades to rotate.

[0047] In some possible implementations, the linkage includes a first linkage and a second linkage, one end of the first linkage is connected to the drive assembly, and the other end is rotatably connected to the second linkage, and the second linkage is rotatably connected to a plurality of the oscillating blades;

[0048] The drive assembly drives the second link to move relative to the mounting plate via the first link, and the second link drives the plurality of the oscillating blades to rotate.

[0049] With the above arrangement, the drive assembly can use the first link to drive the second link, and the second link to drive the oscillating blade, making the position of the drive assembly more flexible.

[0050] In some possible implementations, the oscillating blade assembly further includes a rack and a plurality of gears, each gear being coaxially fixedly connected to one of the oscillating blade components. The rack and the plurality of gears mesh with each other. The rack is movably disposed relative to the mounting plate. The rack drives the plurality of gears to rotate, and the gears drive the oscillating blade component to rotate.

[0051] With the above arrangement, the drive unit can drive the rack to move, thereby driving multiple oscillating blades that are fixedly connected to the gear on the same axis to rotate.

[0052] In some possible implementations, the oscillating blades are configured as multiple, and the multiple oscillating blades are divided into two groups, with the two groups of oscillating blades arranged at intervals in the air outlet along the left and right directions.

[0053] The two sets of oscillating blades may rotate in the same or different directions; when the two sets of oscillating blades rotate in the same direction, the wind-blocking protrusions on the two sets of oscillating blades are located at the same end of the soft air hole along the axial direction; when the two sets of oscillating blades rotate in opposite directions, the wind-blocking protrusions on the two sets of oscillating blades are located at different ends of the soft air hole along the axial direction.

[0054] With the above arrangement, multiple oscillating blades are divided into two groups. The specific position of the windproof protrusion on the oscillating blade can be determined according to whether the rotation directions of the two groups of oscillating blades are the same or different. Thus, the oscillating blades can have good wind guiding and wind softening effects in different application scenarios.

[0055] On the other hand, an air conditioner is provided, which includes the louver assembly described in this application.

[0056] The air conditioner of this application uses the louver assembly of this application and has all the beneficial technical effects of all embodiments herein.

[0057] In some possible implementations, the air conditioner includes a swing mode and a gentle wind mode. In the swing mode, the maximum acute angle between the oscillating blade and the air outlet direction is α1, and in the gentle wind mode, the minimum acute angle between the oscillating blade and the air outlet direction is α2, wherein α1 is less than or equal to α2.

[0058] With the above arrangement, the air conditioning system can achieve both a swing mode and a gentle breeze mode. In the swing mode, the louvers can achieve a left-right swing effect, and in the gentle breeze mode, the wind deflector protrusion can guide the airflow through the gentle breeze hole, giving the louvers a good gentle breeze effect.

[0078] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by one of ordinary skill in the art.

[0079] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0080] On the one hand, combined with Figure 1 and Figure 2 As shown, this embodiment provides a swaying blade assembly including: a swaying blade component 11; the swaying blade component 11 is provided with a gentle air hole 11a and a windproof protrusion 11b.

[0081] The soft wind hole 11a is arranged through the thickness direction of the blade 11, and the windproof protrusion 11b is set close to the soft wind hole 11a and located on one side of the soft wind hole 11a. The windproof protrusion 11b is used to enhance the soft wind formed by the airflow by the soft wind hole 11a.

[0082] In this embodiment, the oscillating blade assembly is disposed at the air outlet 100. The oscillating blade 11 in the oscillating blade assembly has a gentle breeze hole 11a and a windproof protrusion 11b. When the oscillating blade 11 is arranged at an angle to the air outlet direction 001, and the windproof protrusion 11b faces away from the air outlet airflow and is located on the leeward side of the gentle breeze hole 11a, a portion of the airflow blowing out of the air outlet 100 directly facing the gentle breeze hole 11a can directly enter the gentle breeze hole 11a. The other portion of the airflow facing the oscillating blade 11 is guided into the gentle breeze hole 11a by the windproof protrusion 11b as it flows with the oscillating blade 11. Thus, a gentle breeze effect can be achieved without keeping the oscillating blade 11 perpendicular to the air outlet direction 001. Moreover, since the gentle breeze hole 11a has a certain angle of inclination to the air outlet direction 001, the gentle breeze airflow blowing out of the gentle breeze hole 11a also has a certain directionality, which can achieve gentle breeze delivery to specific areas on the left and right sides.

[0083] In some possible implementations, when the air outlet 100 and the oscillating blade 11 are tilted opposite each other in the direction 001 of the air outlet 100, and the windproof protrusion 11b is opposite to the airflow, the windproof protrusion 11b is located on the leeward side of the soft air hole 11a.

[0084] With the above arrangement, the windproof protrusion 11b can guide the airflow flowing along the surface of the oscillating blade 11 into the gentle air hole 11a, thereby improving the gentle airflow effect of the oscillating blade 11.

[0085] Combination Figure 3 and Figure 4 As shown, in some possible implementation schemes, the height of the windshield protrusion 11b is h, and the diameter of the wind-blowing hole 11a is D, where the value of h / D is 0.2-0.8.

[0086] When the height h of the windshield protrusion 11b and the diameter D of the wind-softening hole 11a meet the above-mentioned value range, the oscillating blade 11 not only has good wind guiding performance, but also good wind-softening performance.

[0087] In some examples, the ratio h / D of the height h of the windshield protrusion 11b and the diameter D of the windbreak hole 11a is, for example, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, etc.

[0088] Combination Figure 4 As shown, in some possible implementations, the windshield protrusion 11b is attached to the edge of the soft air hole 11a, or the windshield protrusion 11b and the edge of the soft air hole 11a are spaced apart.

[0089] With the above arrangement, the windproof protrusion 11b and the wind-softening hole 11a can be arranged close together or spaced apart, which provides greater flexibility.

[0090] Combination Figure 2 As shown, in some possible implementations, the windproof protrusion 11b is arranged in an arc shape around the edge of the soft wind hole 11a.

[0091] With the above arrangement, the windproof protrusion 11b is constructed in an arc shape and is arranged around the edge of the soft air hole 11a, so that the windproof protrusion 11b can guide the airflow into the soft air hole 11a in a certain range of circumferential directions.

[0092] Combination Figure 2 As shown, in some possible implementations, the central angle of the windshield protrusion 11b around the axis of the wind-blown hole 11a ranges from 120 to 240 degrees.

[0093] When the value of the central angle of the windshield protrusion 11b around the wind-blown hole 11a meets the above range, the windshield protrusion 11b has a better wind-blocking effect.

[0094] In some examples, the central angle of the windshield protrusion 11b is, for example, 120 degrees, 130 degrees, 150 degrees, 180 degrees, 200 degrees, 220 degrees, 240 degrees, etc. For example, the central angle of the windshield protrusion 11b is 180 degrees.

[0095] Combination Figure 2 , Figure 3 and Figure 4 As shown, in some possible implementation schemes, multiple soft air holes 11a are provided, and multiple soft air holes 11a are arranged at intervals on the oscillating blade 11. A windproof protrusion 11b is provided on one side of some or all of the soft air holes 11a.

[0096] With the above arrangement, multiple soft air holes 11a are arranged on the oscillating blade 11, which has a better soft air effect. Moreover, it is only necessary to arrange a windproof protrusion 11b on one side of some of the soft air holes 11a to guide some airflow into the soft air holes 11a, thereby improving the soft air effect of the oscillating blade 11.

[0097] For example, a windproof protrusion 11b is provided on one side of all the soft air holes 11a.

[0098] Combination Figure 2 As shown, in some possible implementations, the projections of two adjacent windshield protrusions 11b arranged along the rotation axis of the swashplate 11 overlap in the air outlet direction 001.

[0099] With the above arrangement, two adjacent windproof protrusions 11b can form a continuous windproof effect in the direction of rotation, thereby guiding the overall airflow to the soft air hole 11a, resulting in a better air guiding effect.

[0100] In some possible implementations, windproof protrusions 11b are respectively provided at both ends of the soft wind hole 11a along the axial direction, located on the same side of the axis of the soft wind hole 11a.

[0101] With the above arrangement, the two ends of the soft wind hole 11a have windproof protrusions 11b, so that no matter which of the two sides 1101 of the oscillating blade 11 faces the air outlet direction 001, the windproof protrusions 11b can guide the airflow into the soft wind hole 11a, ensuring the double-sided soft wind performance of the oscillating blade 11.

[0102] In some possible implementations, the porosity of the flap 11 ranges from 5% to 50%.

[0103] When the porosity of the oscillating blade 11 meets the above-mentioned value range, the oscillating blade 11 has a good wind-softening effect.

[0104] In some examples, the porosity of the flap 11 is taken as, for example, 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, etc.

[0105] Combination Figure 4 As shown, in some possible implementations, the inner diameter of the soft air hole 11a is at least partially different from the inner diameter of the end.

[0106] With the above arrangement, the soft wind hole 11a has a variety of structural features, which can meet different soft wind requirements.

[0107] In some examples, the shape of the soft air hole 11a can be a frustum, a pyramid, a trumpet, a gourd, etc., with the inner diameters at at least two positions along the axis being different. For example, in the trumpet and frustum shapes, the inner diameter at one end is smaller than the inner diameter at the other end, while in the gourd shape, the inner diameters at both ends are larger than the inner diameter in the middle.

[0108] Combination Figure 1 , Figure 5 and Figure 7As shown, in some possible implementations, the oscillating blade assembly 1 also includes a mounting plate 12, on which the oscillating blade 11 is rotatably connected.

[0109] With the above arrangement, the louvered blade 11 can be rotated and supported by the mounting plate 12, so that it can be installed on air conditioners or other air outlet equipment to achieve the functions of guiding and softening air.

[0110] In some possible implementations, the mounting plate 12 is disposed inside the air outlet 100 of the air conditioner, and the airflow inside the air outlet 100 can flow through the sway blade 11, thereby being guided by the sway blade 11 to sweep the air or to soften the airflow.

[0111] Combination Figure 5 and Figure 7 As shown, in some possible implementation schemes, multiple oscillating blades 11 are provided, and multiple oscillating blades 11 are arranged at intervals on the mounting plate 12 along the extension direction of the mounting plate 12. Some or all of the oscillating blades 11 are provided with windproof protrusions 11b.

[0112] With the above arrangement, the oscillating blade assembly 1 has multiple oscillating blades 11, and is installed sequentially at intervals using the mounting plate 12. Thus, the oscillating blade assembly 1 can achieve wind guiding and wind softening functions within the extended space of the mounting plate 12. Furthermore, some or all of the oscillating blades 11 are provided with windproof protrusions 11b, which makes the oscillating blade assembly 1 have better wind guiding and wind softening effects.

[0113] Combination Figure 5 and Figure 7 As shown, in some possible implementations, multiple sway blades 11 are divided into a first region, a second region and a third region along the extension direction of the mounting plate 12. The first region and the third region are close to the two ends of the mounting plate 12, respectively, and the second region is located between the first region and the third region.

[0114] The windproof protrusion 11b is provided only in the first region of the oscillating blade 11, or only in the second region of the oscillating blade 11, or only in the third region of the oscillating blade 11, or only in the first and third regions of the oscillating blade 11.

[0115] Alternatively, of two adjacent sway blades 11, only one sway blade 11 may be provided with a windproof protrusion 11b.

[0116] With the above arrangement, the multiple oscillating blades 11 are divided into three areas. Each oscillating blade 11 in each area can be selectively equipped with or without a windproof protrusion 11b. This is to take into account that the oscillating blades 11 in different areas have different requirements for guiding and softening the wind. The windproof protrusion 11b is arranged on the oscillating blades 11 in areas with higher requirements for softening the wind, while the windproof protrusion 11b is not required on the oscillating blades 11 in areas with lower requirements for softening the wind.

[0117] Combination Figure 6 and Figure 8 As shown, in some possible implementations, the oscillating blade assembly 1 also includes a connecting rod 14, which is movably arranged relative to the mounting plate 12. Multiple oscillating blades 11 are rotatably connected to the connecting rod 14, and the connecting rod 14 drives the multiple oscillating blades 11 to rotate.

[0118] With the above arrangement, the oscillating blade 11 can be driven by the connecting rod 14 to achieve synchronous rotation, thereby achieving synchronous air guiding or gentle air effect.

[0119] Combination Figure 6 and Figure 8 As shown, in some possible implementations, the oscillating blade assembly 1 further includes a drive assembly 13; the drive assembly 13 is connected to one of the oscillating blades 11, and the drive assembly 13 is used to drive the oscillating blade 11 to rotate, and the oscillating blade 11 drives the other oscillating blades 11 to rotate through the connecting rod 14.

[0120] In this embodiment, the drive component 13 drives one oscillating blade 11 to rotate, and then drives the connecting rod 14 to move through the oscillating blade 11. Finally, the connecting rod 14 drives the remaining oscillating blades 11 to rotate, thus achieving the driving effect of a single drive component 13 driving all the oscillating blades 11 to rotate.

[0121] Among some possible implementations, refer to Figure 6 and Figure 8 As shown, in some possible implementations, each oscillating blade 11 includes a rotating shaft structure 11c, which is used to rotatably support the oscillating blade 11 on the mounting plate 12. The end of the rotating shaft structure 11c is provided with a coupling hole 111 and a pivot shaft 112, wherein the coupling hole 111 is located on the rotation axis of the oscillating blade 11, and the pivot shaft 112 is located on one side of the rotation axis. The coupling hole 111 is connected to the drive assembly 13 for transmission. The drive assembly 13 can provide rotational torque to the oscillating blade 11 through the coupling hole 111. The pivot hole 141 on the connecting rod 14 is rotatably connected to the pivot shaft 112, so that when the drive assembly 13 drives the oscillating blade 11 to rotate, the oscillating blade 11 can drive the connecting rod 14 to move.

[0122] For example, the drive assembly 13 includes a drive unit 131 and a coupling 132. The drive unit 131 may be an electric motor. One end of the coupling 132 is connected to the output shaft of the drive unit 131, and the other end is connected to the coupling hole 111. The coupling 132 and the coupling hole 111 are both polygonal structures, such as hexagonal structures.

[0123] Combination Figure 9 As shown, in some possible implementations, the oscillating blade assembly 1 further includes a drive assembly 13; the drive assembly 13 is connected to the connecting rod 14, and the drive assembly 13 is used to drive the connecting rod 14 to move, and the connecting rod 14 drives multiple oscillating blades 11 to rotate.

[0124] In this embodiment, the drive component 13 moves through the connecting rod 14, which can drive all the oscillating blades 11 to rotate, thus achieving the driving effect of a single drive component 13 driving all the oscillating blades 11 to rotate.

[0125] Combination Figure 9 As shown, in some possible implementations, the linkage 14 includes a first linkage 14a and a second linkage 14b. One end of the first linkage 14a is connected to the drive assembly 13, and the other end is rotatably connected to the second linkage 14b. The second linkage 14b is rotatably connected to a plurality of oscillating blades 11.

[0126] The drive assembly 13 drives the second link 14b to move relative to the mounting plate 12 via the first link 14a, and the second link 14b drives multiple oscillating blades 11 to rotate.

[0127] With the above arrangement, the drive assembly 13 can drive the second link 14b using the first link 14a, and drive the oscillating blade 11 using the second link 14b, making the arrangement of the drive assembly 13 more flexible.

[0128] Combination Figure 10 As shown, in some possible implementations, the oscillating blade assembly 1 also includes a rack 16 and a plurality of gears 15. Each gear 15 is coaxially fixedly connected to an oscillating blade component 11. The rack 16 and the plurality of gears 15 mesh with each other. The rack 16 is movably disposed relative to the mounting plate 12. The rack 16 drives the plurality of gears 15 to rotate, and the gears 15 drive the oscillating blade component 11 to rotate.

[0129] With the above arrangement, the drive unit 131 can move by driving the rack 16, thereby driving the multiple oscillating blades 11 that are coaxially fixedly connected to the gear 15 to rotate.

[0130] Combination Figure 1 As shown, in some possible implementation schemes, multiple oscillating blades 11 are provided, and the multiple oscillating blades 11 are divided into two groups. The two groups of oscillating blades 11 are arranged at intervals in the air outlet 100 along the left and right directions.

[0131] The two sets of oscillating blades 11 may rotate in the same or different directions. When the two sets of oscillating blades 11 rotate in the same direction, the windproof protrusions 11b on the two sets of oscillating blades 11 are located at the same end along the axial direction of the soft wind hole 11a. When the two sets of oscillating blades 11 rotate in opposite directions, the windproof protrusions 11b on the two sets of oscillating blades 11 are located at different ends along the axial direction of the soft wind hole 11a.

[0132] With the above arrangement, the multiple oscillating blades 11 are divided into two groups. The specific position of the windproof protrusion 11b on the oscillating blade 11 can be determined according to whether the rotation directions of the two groups of oscillating blades 11 are the same or different. Thus, the oscillating blades 11 can have good air guiding and softening effects in different application scenarios, realizing left and right zone air guiding and / or softening. For example, left-side air guiding and right-side softening, or left-side softening and right-side air guiding.

[0133] On the other hand, combining Figure 1 As shown, this application provides an air conditioner, which includes the louver assembly 1 of this application.

[0134] The air conditioner in this embodiment uses the louver assembly 1 of this application, and has all the beneficial technical effects of all embodiments herein.

[0135] Combination Figure 11 and Figure 12 As shown, in some possible implementation schemes, the air conditioner includes a swing mode and a gentle wind mode. In the swing mode, the maximum acute angle between the oscillating blade 11 and the air outlet direction 001 is α1, and in the gentle wind mode, the minimum acute angle between the oscillating blade 11 and the air outlet direction 001 is α2, wherein α1 is less than or equal to α2.

[0136] With the above arrangement, the air conditioning system can realize the swing mode and the gentle wind mode. In the swing mode, the wind deflector 11b can block the airflow from entering the gentle wind hole 11a, so that the oscillating blade 11 has a better air guiding effect. In the gentle wind mode, the wind deflector 11b can guide the airflow through the gentle wind hole 11a, and the oscillating blade 11 has a good gentle wind effect.

[0137] For example, in the swing mode, the acute angle between the oscillating blade 11 and the air outlet direction 001 is in the range of 20-70°, and in the gentle wind mode, the acute angle between the oscillating blade 11 and the air outlet direction 001 is in the range of 70-90°.
