Description

Technical Field

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

[0002] During operation, air conditioners typically draw in indoor air, cool it down, and then blow it out. To achieve left-right airflow, swivel blades that can rotate left and right are usually installed at the air outlet of the air conditioner.

[0003] However, in some cases, the distance between the end vane and the side wall of the air outlet is relatively close. When the vane guides the airflow, it will direct the airflow to the side wall of the air outlet, thus affecting the air outlet performance of the air conditioner. Utility Model Content

[0004] This application provides an air conditioner that can solve the problem that the air outlet effect is reduced due to the influence of the end louver component on the side wall of the air outlet.

[0005] The technical solution is as follows: An air conditioner, characterized in that the air conditioner includes: an air outlet and a louver assembly; The louver assembly is installed inside the air outlet; The oscillating blade assembly includes multiple rotatably arranged oscillating blades. The oscillating blades near the end of the air outlet are provided with through holes extending along the thickness direction. The air guide surface of the oscillating blades is provided with air guide protrusions near the through holes. When the louver at the end guides the airflow from the outlet toward the sidewall at the end of the outlet, the air guide protrusion is used to guide the airflow into the through hole.

[0006] The air conditioner of this application has a through hole and a guide protrusion on the end of the louver assembly near the air outlet. When the louver assembly is arranged at an angle to the air outlet direction and guides the air left and right, the guide protrusion faces away from the air outlet airflow. When the guide protrusion is located on the leeward side of the through hole, the airflow blown out of the air outlet will be guided into the through hole by the obstruction of the guide protrusion, so that it will not be directly guided to the inner side wall of the air outlet. This part of the airflow can participate in the air outlet and improve the air outlet effect of the air conditioner.

[0007] In some possible implementations, when the air outlet and the louver are tilted opposite each other and the air guide protrusion is opposite to the airflow, the air guide protrusion is located on the leeward side of the through hole.

[0008] With the above arrangement, the air guide protrusions can guide the airflow flowing along the surface of the oscillating blade into the through hole, thereby improving the air guiding effect of the oscillating blade.

[0009] In some possible implementations, the height of the air guide protrusion is h, and the diameter of the through hole is D, where the value of h / D is 0.2-0.8.

[0010] When the height h of the air guide protrusion and the diameter D of the through hole meet the above-mentioned value range, the oscillating blade not only has good air guiding performance, but also good air outlet performance.

[0011] In some possible implementations, the air guide protrusion is fitted to the edge of the through hole, or the air guide protrusion is spaced apart from the edge of the through hole.

[0012] With the above arrangement, the air guide protrusions and through holes can be arranged close together or spaced apart, providing greater flexibility.

[0013] In some possible implementations, the air guide protrusion is arranged in an arc shape around the edge of the through hole.

[0014] With the above arrangement, the air guide protrusion is constructed in an arc shape and is arranged around the edge of the through hole, so that the air guide protrusion can guide the airflow into the through hole in a certain range of circumferential directions.

[0015] In some possible implementations, the central angle of the air guide protrusion around the axis of the through hole ranges from 120 to 240 degrees.

[0016] When the value of the central angle of the air guide protrusion around the through hole meets the above range, the air guide protrusion has a better air guiding effect.

[0017] In some possible implementations, multiple through holes are provided, and the multiple through holes are arranged at intervals on the blade component, with the air guide protrusion provided on one side of some or all of the through holes.

[0018] With the above arrangement, multiple through holes are arranged on the oscillating blades, which has a better wind-softening effect. Moreover, only one side of some of the through holes needs to be arranged with a guide protrusion to guide part of the airflow into the through holes, thereby improving the wind-guiding effect of the oscillating blades.

[0019] In some possible implementations, the projections of two adjacent air guide protrusions arranged along the rotation axis of the blade overlap in the air outlet direction.

[0020] With the above arrangement, two adjacent air guide protrusions can form a continuous wind-blocking effect in the direction of the rotation axis, thereby guiding the overall airflow through the through hole and achieving a better air outlet effect.

[0021] In some possible implementations, the end blade is also provided with a windproof protrusion. The windproof protrusion and the air guide protrusion are located at the two ends of the through hole, respectively. When the end blade guides the airflow of the air outlet away from the side wall of the air outlet end, the windproof protrusion is used to block the airflow from entering the through hole.

[0022] With the above arrangement, when the end blades are guided in the direction away from the side wall of the air outlet, in order to prevent the airflow from passing through the through hole and blowing towards the side wall of the air outlet, a windproof protrusion is arranged on the other side of the through hole, which can block the airflow from entering the through hole and improve the air guiding effect of the blades.

[0023] In some possible implementations, the louvered blade, located away from the end of the air outlet, has a through hole extending along the thickness direction.

[0024] With the above arrangement, the oscillating blades away from the end have through holes. When the airflow from the air outlet blows onto the surface of this part of the oscillating blades, the airflow can pass through the through holes and be dispersed into a gentle breeze, thus achieving a gentle airflow effect.

[0025] In some possible implementations, a wind-blocking protrusion is provided on the guide surface of the louvered member away from the end of the air outlet, near the through hole; When the louvered blades located away from the end of the air outlet guide the airflow at the air outlet, the windproof protrusion is used to block the airflow from entering the through hole.

[0026] When the oscillating blades are arranged at an angle to the airflow direction, with the windshield protrusion facing the airflow and located upstream of the through-hole, at least part of the airflow blowing from the outlet will be blocked by the windshield protrusion. This prevents the airflow from directly entering the through-hole and instead directs it to flow along the side of the oscillating blades, achieving normal airflow guidance. Furthermore, the airflow blocked by the windshield protrusion will create turbulence on the outside of the through-hole, hindering the entry of unblocked airflow into the through-hole and further guiding the airflow along the side of the oscillating blades, thereby improving the airflow guidance effect of the oscillating blades.

[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 air guiding effect.

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

[0030] With the above arrangement, the through holes have a variety of structural features, which can meet different air guiding requirements.

[0031] In some possible implementations, the blade has a first guide surface and a second guide surface arranged opposite to each other, with the air guide protrusion on one of the two blades at the ends located on the first guide surface and the air guide protrusion on the other located on the second guide surface.

[0032] With the above arrangement, the air guide protrusions of the two end blades are arranged opposite each other, which can adapt to the different relative positions between the blades and the side wall of the air outlet for air guidance. The airflow at the air outlet will not blow towards the corresponding side wall at either end, thus improving the overall air outlet effect of the air conditioner.

[0033] In some possible implementations, the blade assembly further includes a mounting plate, with a plurality of blades spaced apart on the mounting plate along its extension direction.

[0034] With the above arrangement, the oscillating blade assembly has multiple oscillating blades, and they are installed sequentially at intervals using a mounting plate, so that the oscillating blade assembly can achieve air guiding and gentle air functions within the extended space of the mounting plate.

[0035] 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.

[0036] 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.

[0037] In some possible implementations, the leaf assembly further includes a drive assembly; 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.

[0038] 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.

[0039] In some possible implementations, the leaf assembly further includes a drive assembly; 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.

[0040] 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.

[0041] 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; 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.

[0042] 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.

[0043] 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.

[0044] 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. Attached Figure Description

[0050] 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.

[0051] 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.

[0052] Combination Figure 1 and Figure 2 As shown, this embodiment provides an air conditioner, which includes an air outlet 100 and a louver assembly 200; the louver assembly 200 is installed inside the air outlet 100.

[0053] The oscillating blade assembly 200 includes a plurality of rotatably arranged oscillating blades 11. The oscillating blades 11 near the end of the air outlet 100 are provided with through holes 11a extending along the thickness direction. The air guide surface 1101 of the oscillating blades 11 is provided with air guide protrusions 11b near the through holes 11a.

[0054] When the end vane 11 guides the airflow of the outlet 100 toward the side wall of the outlet end, the air guide protrusion 11b is used to guide the airflow into the through hole 11a.

[0055] In this embodiment, the air conditioner is installed at the air outlet 100. The louvered blade assembly 200 has a through hole 11a and a guide protrusion 11b on the end of the louvered blade assembly 200 near the air outlet 100. When the louvered blade assembly 11 is arranged at an angle to the air outlet direction 001 and guides the air left and right, the guide protrusion 11b faces away from the air outlet airflow. When the guide protrusion 11b is located on the leeward side of the through hole 11a, the airflow blown out of the air outlet 100 will be guided into the through hole 11a by the obstruction of the guide protrusion 11b, so that it will not be directly guided to the inner wall of the air outlet 100. This part of the airflow can participate in the air outlet and improve the air outlet effect of the air conditioner.

[0056] In some possible implementations, when the air outlet 100 and the oscillating blade 11 are tilted opposite each other in the air outlet direction 001, and the air guide protrusion 11b is opposite to the air outlet airflow, the air guide protrusion 11b is located on the leeward side of the through hole 11a.

[0057] With the above arrangement, the air guide protrusion 11b can guide the airflow flowing along the surface of the oscillating blade 11 into the through hole 11a, thereby improving the air guiding effect of the oscillating blade 11.

[0058] Combination Figure 3 and Figure 4 As shown, in some possible implementation schemes, the height of the air guide protrusion 11b is h, and the diameter of the through hole 11a is D, where the value of h / D is 0.2-0.8.

[0059] When the height h of the air guide protrusion 11b and the diameter D of the through hole 11a meet the above-mentioned value range, the oscillating blade 11 not only has good air guiding performance, but also good gentle wind performance.

[0060] In some examples, the ratio h / D of the height h of the air guide protrusion 11b and the diameter D of the through hole 11a is taken as, for example, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, etc.

[0061] Combination Figure 4 As shown, in some possible implementations, the air guide protrusion 11b is fitted to the edge of the through hole 11a, or the air guide protrusion 11b is spaced apart from the edge of the through hole 11a.

[0062] With the above arrangement, the air guide protrusion 11b and the through hole 11a can be arranged close together or spaced apart, which provides greater flexibility.

[0063] Combination Figure 2 As shown, in some possible implementations, the air guide protrusion 11b is arranged in an arc shape around the edge of the through hole 11a.

[0064] With the above arrangement, the air guide protrusion 11b is constructed in an arc shape and is arranged around the edge of the through hole 11a, so that the air guide protrusion 11b can guide the airflow into the through hole 11a in a certain range of circumferential directions.

[0065] Combination Figure 2 As shown, in some possible implementations, the central angle of the air guide protrusion 11b around the axis of the through hole 11a ranges from 120 to 240 degrees.

[0066] When the value of the central angle of the air guide protrusion 11b around the through hole 11a meets the above range, the air guide protrusion 11b has a better wind-blocking effect.

[0067] In some examples, the central angle of the air guide 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 air guide protrusion 11b is 180 degrees.

[0068] Combination Figure 2 , Figure 3 and Figure 4 As shown, in some possible implementations, multiple through holes 11a are provided, and multiple through holes 11a are arranged at intervals on the oscillating blade 11. A guide protrusion 11b is provided on one side of some or all of the through holes 11a.

[0069] With the above arrangement, multiple through holes 11a are arranged on the oscillating blade 11, which has a better wind-softening effect. Moreover, only one side of some of the through holes 11a needs to be arranged with a guide protrusion 11b to guide part of the airflow into the through holes 11a, thereby improving the wind-guiding effect of the oscillating blade 11.

[0070] For example, a guide protrusion 11b is provided on one side of all through holes 11a.

[0071] Combination Figure 2 As shown, in some possible implementations, the projections of two adjacent air guide protrusions 11b arranged along the rotation axis of the oscillating blade 11 on the air outlet direction 001 overlap.

[0072] With the above arrangement, two adjacent air guide protrusions 11b can form a continuous wind-blocking effect in the direction of the rotation axis, thereby guiding the overall airflow through the through hole 11a, resulting in a better air guiding effect.

[0073] Combination Figure 3 and Figure 5 As shown, in some possible implementations, the end vane 11 is also provided with a windproof protrusion 11d. The windproof protrusion 11d and the air guide protrusion 11b are located at the two ends of the through hole 11a, respectively. When the end vane 11 guides the airflow of the air outlet 100 away from the side wall of the end of the air outlet 100, the windproof protrusion 11d is used to block the airflow from entering the through hole 11a.

[0074] With the above arrangement, when the end vane 11 is guided in the direction away from the end side wall of the air outlet 100, in order to prevent the airflow from passing through the through hole 11a and blowing towards the side wall of the air outlet 100, a windproof protrusion 11d is arranged on the other side of the through hole 11a, which can block the airflow from entering the through hole 11a and improve the air guiding effect of the vane 11.

[0075] Combination Figure 2 and Figure 6 As shown, in some possible implementations, the louver 11 at the end away from the air outlet 100 is provided with a through hole 11a extending along the thickness direction.

[0076] With the above arrangement, the oscillating blade 11 far from the end has a through hole 11a. When the airflow from the air outlet 100 blows onto the surface of this part of the oscillating blade 11, the airflow can pass through the through hole 11a and be dispersed into a gentle breeze, thus achieving a gentle airflow effect.

[0077] Combination Figure 2 and Figure 5 As shown, in some possible implementations, a windproof protrusion 11d is provided on the guide surface of the louver 11 away from the end of the air outlet 100, near the through hole 11a.

[0078] When the louver 11, which is away from the end of the air outlet 100, guides the airflow of the air outlet 100, the windproof protrusion 11d is used to block the airflow from entering the through hole 11a.

[0079] When the oscillating blade 11 is arranged at an angle to the air outlet direction 001, with the windproof protrusion 11d facing the air outlet and located upstream of the through hole 11a, at least part of the air blown out of the air outlet 100 will be blocked by the windproof protrusion 11d. This prevents the airflow from directly entering the through hole 11a, instead allowing it to flow along the guide surface 1101 of the oscillating blade 11, thus achieving normal airflow guidance. Furthermore, the airflow blocked by the windproof protrusion 11d will form turbulence outside the through hole 11a, hindering the airflow not blocked by the windproof protrusion 11d from entering the through hole 11a, further guiding the airflow along the guide surface 1101 of the oscillating blade 11, thereby improving the airflow guidance effect of the oscillating blade 11.

[0080] In some possible implementations, the porosity of the flap 11 ranges from 5% to 50%.

[0081] When the porosity of the oscillating blade 11 meets the above-mentioned value range, the oscillating blade 11 has a good wind-softening effect.

[0082] 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.

[0083] Combination Figure 4 and Figure 5 As shown, in some possible implementations, the inner diameter inside the through hole 11a is at least partially different from the inner diameter at the end.

[0084] With the above arrangement, the through hole 11a has a variety of structural features, which can meet different air guiding or gentle air requirements.

[0085] In some examples, the shape of the through hole 11a can be frustum, pyramid, trumpet, 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.

[0086] Combination Figure 3 , Figure 4 and Figure 5 As shown, in some possible implementations, the oscillating blade 11 has a first guide surface 1101a and a second guide surface 1101b arranged opposite to each other. The air guide protrusion 11b on one of the two oscillating blades 11 at the end is located on the first guide surface 1101a, and the air guide protrusion 11b on the other is located on the second guide surface 1101b.

[0087] With the above arrangement, the air guide protrusions 11b of the two end louvers 11 are arranged opposite to each other, which can adapt to the different relative positions between the louvers 11 and the side wall of the air outlet 100 for air guidance. The airflow of the air outlet 100 will not blow towards the corresponding side wall at either end, so the overall air outlet effect of the air conditioner is better.

[0088] Combination Figure 1 As shown, in some possible implementations, the oscillating blade assembly 200 also includes a mounting plate 12, with a plurality of oscillating blades 11 spaced apart on the mounting plate 12 along the extending direction of the mounting plate 12.

[0089] With the above arrangement, the oscillating blade assembly 200 has multiple oscillating blades 11, and is installed sequentially at intervals using the mounting plate 12, so that the oscillating blade assembly 200 can achieve air guiding and gentle air functions within the extended space of the mounting plate 12.

[0090] Combination Figures 7 to 10 As shown, in some possible implementations, the oscillating blade assembly 200 also includes a connecting rod 14, which is movably disposed 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.

[0091] 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.

[0092] Combination Figure 8 and Figure 10 As shown, in some possible implementations, the oscillating blade assembly 200 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.

[0093] 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.

[0094] Among some possible implementations, refer to Figure 8 and Figure 10As shown, 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. 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. Thus, when the drive assembly 13 drives the oscillating blade 11 to rotate, the oscillating blade 11 can drive the connecting rod 14 to move.

[0095] 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.

[0096] Combination Figure 11 As shown, in some possible implementations, the oscillating blade assembly 200 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.

[0097] 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.

[0098] Combination Figure 11 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.

[0099] 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.

[0100] 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.

[0101] Combination Figure 12As shown, in some possible implementations, the oscillating blade assembly 200 also includes a rack 16 and a plurality of gears 15. Each gear 15 is coaxially fixedly connected to an oscillating blade 11. The rack 16 and the plurality of gears 15 mesh with each other.
