Description

Technical Field

[0001] The present invention belongs to the technical field of air conditioners, and particularly relates to an air deflector anti-vibration structure and an air conditioner having the same. Background Art

[0002] When the air deflector of an air conditioner performs up-and-down air sweeping, due to the influence of the blowing, the air flow organization will change, resulting in uneven force on the air deflector. As a result, the air deflector will vibrate and generate noise. Seriously, the air deflector may even resonate with the housing or fall off the housing, affecting the reliability of the air deflector. The problem of air deflector vibration has always been a major bottleneck in the mass production of split air conditioners, and there has been no good solution. Summary of the Invention

[0003] Therefore, the present invention provides an air deflector anti-vibration structure, which can overcome the deficiency that the air deflector of the existing air conditioner is prone to vibrate and generate noise when performing up-and-down air sweeping due to the influence of the blowing.

[0004] To solve the above problems, the present invention provides an air deflector anti-vibration structure, including: an air deflector and a bottom case. The bottom case has an air outlet, and a movement track is formed on one side wall of the air outlet. The air deflector is rotatably assembled on the bottom case, and a damping component is provided on the air deflector. At least part of the damping component is in interference fit in the movement track. When the air deflector rotates relative to the bottom case to adjust the blowing direction of the air outlet, the damping component can slide along the guiding direction of the movement track following the rotation of the air deflector.

[0005] In some embodiments, the damping component includes a damping body, and the damping body has a sliding fit portion provided on the air deflector. At least part of the sliding fit portion is in interference fit in the movement track, and the sliding fit portion can slide along the movement track.

[0006] In some embodiments, the material of the damping body is an elastic wear-resistant material.

[0007] In some embodiments, the damping component further includes a fixing structure. The fixing structure includes an insertion body provided on the side of the air deflector facing the movement track, and the sliding fit portion is sleeved on the insertion body.

[0008] In some embodiments, the damping body further has an assembly connection portion, and the assembly connection portion is connected to the sliding fit portion. The fixing structure further includes a fixing block provided on the air deflector. The insertion body is connected to the end face of the fixing block facing the movement track. When the damping body is assembled on the fixing structure, the assembly connection portion can be snap-connected to the fixing block.

[0009] In some embodiments, the assembly connection part includes a snap part, the fixing block has a clamping head, and the snap part can be snapped onto the clamping head.

[0010] In some embodiments, an installation hole penetrating the axial direction of the sliding fit part is formed in the sliding fit part, the insert has a first insertion part, and the first insertion part is inserted into the installation hole in a clearance fit manner.

[0011] In some embodiments, the insert further has a second insertion part, the first insertion part is connected to the fixing block through the second insertion part, and the second insertion part is inserted into the installation hole in an interference fit manner.

[0012] In some embodiments, the outer circumferential side wall of the second insertion part is adapted to the inner surface shape of the installation hole.

[0013] In some embodiments, the radial cross-section of the second insertion part is a first polygon, the radial cross-section of the installation hole is a second polygon, the length difference between each side of the first polygon and each corresponding side of the second polygon is ΔL, and 0 < ΔL ≤ 1 mm; alternatively, the radial cross-section of the second insertion part is a first circle, the radial cross-section of the installation hole is a second circle, the diameter of the first circle is R1, the diameter of the second circle is R2, and 0 < R1 - R2 ≤ 1 mm.

[0014] In some embodiments, the sliding fit part has an outer circumferential side wall, the outer diameter of the sliding fit part is R3, the movement track is an arc track with a constant width, the width of the movement track is L, and 0 < R3 - L ≤ 1 mm.

[0015] The present invention also provides an air conditioner, including the above-mentioned air deflector anti-shake structure.

[0016] The present invention provides an air deflector anti-shake structure and an air conditioner having the same. When the air conditioner works, driven by the air deflector motor, the air deflector rotates around the rotation axis in the air outlet to adjust the blowing direction of the air outlet on the bottom case. At the same time, the air deflector also drives the damping component to slide in the movement track. Since at least part of the damping component is in the movement track in an interference fit manner, appropriate frictional resistance will be generated during the sliding process of the damping component to form shock absorption and buffering, making the operation of the air deflector more stable, thus significantly improving the shaking and noise generated by the air deflector due to the disturbance of the air conditioner air during operation, and more avoiding the detachment of the air deflector. At the same time, since the shaking of the air deflector easily causes torsional torque on the rotation axis and the motor output shaft, after the shaking of the air deflector is effectively improved, the torsional torque on the air deflector motor can be reduced, thereby extending the service life of the air deflector motor.

[0025] Refer to in combination Figures 1 to 6As shown in the figure, according to an embodiment of the present invention, a wind deflector anti-vibration structure is provided, including: a wind deflector 1 and a bottom case 2. The bottom case 2 has an air outlet. Preferably, along the length direction of the air outlet, at least one side wall of the air outlet is provided with a movement track 3. The wind deflector 1 is rotatably assembled on the bottom case 2. Preferably, the wind deflector 1 is provided with damping components 4 that are the same in number as and correspond one-to-one with the movement tracks 3. At least part of the damping components 4 is in the movement track 3 in an interference fit manner. When the wind deflector 1 rotates relative to the bottom case 2 to adjust the blowing direction of the air outlet, the damping components 4 can slide along the guiding direction of the movement track 3 following the rotation of the wind deflector 1. In this technical solution, along the length direction of the air outlet, movement tracks 3 can be constructed on both side walls of the air outlet, or only on one of the side walls. In this solution, movement tracks 3 are only constructed on one of the side walls. A rotating shaft 5 is provided on the side of the wind deflector 1 facing the movement track 3. The rotating shaft 5 is rotatably inserted into the side wall where the movement track 3 is constructed. The damping components 4 and the rotating shaft 5 are on the same side, and there is a certain distance between the two in the width direction of the wind deflector 1. When the air conditioner is working, driven by the wind deflector motor, the wind deflector 1 rotates around the rotating shaft 5 in the air outlet to adjust the blowing direction of the air outlet on the bottom case 2. At the same time, the wind deflector 1 also drives the damping components 4 to slide in the movement track 3. Since at least part of the damping components 4 is in the movement track 3 in an interference fit manner, appropriate frictional resistance will be generated during the sliding process of the damping components 4 to form shock absorption and buffering, making the operation of the wind deflector more stable, thus effectively improving the shaking and noise generated by the wind deflector 1 due to the disturbance of the air conditioner wind during operation, and more avoiding the detachment of the wind deflector 1. At the same time, since the shaking of the wind deflector 1 easily causes torsional torque on the rotating shaft 5 and the motor output shaft, after the shaking of the wind deflector 1 is effectively improved, the torsional torque on the wind deflector motor can be reduced, thereby prolonging the service life of the wind deflector motor.

[0026] As a specific implementation manner, the damping component 4 includes a damping body 41. The damping body 41 has a sliding fit portion 411 provided on the wind deflector 1. At least part of the sliding fit portion 411 is in the movement track 3 in an interference fit manner, and the sliding fit portion 411 can slide along the movement track 3.

[0027] In this embodiment, since the sliding fit portion 411 is provided on the wind deflector 1, when the wind deflector 1 rotates, it will drive the sliding fit portion 411 to slide along the movement track 3. Frictional force is generated during the sliding process of the sliding fit portion 411, and this frictional force will make the operation of the wind deflector 1 more stable, effectively solving the problem of the wind deflector 1 shaking caused by the air conditioner wind, that is, setting the sliding fit portion 411 on the wind deflector 1 can prevent the wind deflector 1 from shaking.

[0028] As a specific implementation manner, the material of the damping body 41 is an elastic wear-resistant material.

[0029] In this embodiment, preferably, the damping body 41 is rubber. Rubber not only has a certain elasticity, but also is wear-resistant and heat-resistant. Because the damping body 41 has elasticity, the sliding fit portion 411 of the damping body 41 can be easily installed into the movement track 3 in an interference fit manner. And when the air deflector 1 sweeps up and down in the air outlet, the air deflector 1 can relatively easily drive the sliding fit portion 411 to slide along the movement track 3, avoiding the phenomenon that the sliding fit portion 411 gets stuck in the movement track 3 and cannot move. At the same time, when the sliding fit portion 411 with a certain elasticity slides along the movement track 3, an appropriate frictional resistance can be obtained, so that the operation of the air deflector 1 is more stable, and the jitter of the air deflector 1 is effectively alleviated.

[0030] As a specific implementation manner, the damping assembly 4 further includes a fixing structure 42. The fixing structure 42 includes an insertion body provided on the side of the air deflector 1 facing the movement track 3, and the sliding fit portion 411 is sleeved on the insertion body.

[0031] In this embodiment, because the damping body 41 has elasticity, when the air deflector 1 drives the sliding fit portion 411 to slide along the movement track 3, the sliding fit portion 411 is prone to be distorted and deformed and fall out of the movement track 3. When the sliding fit portion 411 is sleeved on the insertion body of the fixing structure 42, since the insertion body is made of a rigid material, when the sliding fit portion 411 slides along the movement track 3, under the action of the insertion body, even if the sliding fit portion 411 is subjected to frictional force, its amount of distortion and deformation will be very small, so as to ensure that the sliding fit portion 411 always slides along the movement track 3.

[0032] As a specific implementation manner, the damping body 41 further has an assembly connection portion 412. The assembly connection portion 412 is connected to the sliding fit portion 411. The fixing structure 42 further includes a fixing block 421. The fixing block 421 is provided on the air deflector 1, and the insertion body is connected to the end face of the fixing block 421 facing the movement track 3. When the damping body 41 is assembled on the fixing structure 42, the assembly connection portion 412 can be snap-connected to the fixing block 421.

[0033] In this embodiment, setting the assembly connection portion 412 to be snap-connected to the fixing block 421 can, on the one hand, prevent the damping body 41 from possibly not being removed together with the air deflector 1 but getting stuck in the movement track 3 when the air deflector 1 is disassembled; on the other hand, it can also prevent the damping body 41 from rotating when sliding along the movement track 3.

[0034] As a specific implementation manner, the assembly connection portion 412 includes a snap portion, and the fixing block 421 has a snap head, and the snap portion can be snap-connected to the snap head.

[0035] In this embodiment, in combination with Figure 5 and Figure 6 As shown, the buckle portion of the assembly connection portion 412 is similar to a semi-hollow cylindrical structure. There is a clamping space and an undercut structure inside the buckle portion. The fixing block 421 of the fixing structure 42 has a base platform and a clamping head connected above the base platform. The shape of the clamping head is adapted to the clamping space inside the buckle portion. When the damping body 41 is assembled on the fixing structure 42, the sliding fit portion 411 is sleeved on the insert body, the buckle portion is clamped on the clamping head of the fixing block 421, and the undercut structure inside the buckle portion fits on the end surface of the clamping head facing away from the insert body. With the above design of the buckle portion and the clamping head, the structure is not only simple, but also the buckling effect is good.

[0036] As a specific implementation manner, an installation hole 413 penetrating axially through the sliding fit portion 411 is formed inside the sliding fit portion 411. The insert body has a first insertion portion 422, and the first insertion portion 422 is inserted into the installation hole 413 in a clearance fit manner.

[0037] In this embodiment, the first insertion portion 422 is the part of the insert body located in the movement track 3. The first insertion portion 422 is inserted into the installation hole 413 of the sliding fit portion 411 in a clearance fit manner, and the gap between the outer peripheral side surface of the first insertion portion 422 and the inner surface of the installation hole 413 is evenly distributed. The purpose of the clearance fit is that when the sliding fit portion 411 and the movement track 3 on the bottom case 2 are press-fitted with interference, the gap will enable the sliding fit portion 411 to have an elastic deformation space, which can prevent the damping body 41 from making hard contact with the side wall of the movement track 3, avoid excessive wear, and extend the service life of the damping body 41. At the same time, the unilateral gap between the outer peripheral side surface of the first insertion portion 422 and the inner surface of the installation hole 413 cannot be too large, otherwise the sliding fit portion 411 cannot generate a large enough friction force when sliding along the movement track 3, and thus cannot effectively improve the jitter of the air deflector 1. In this embodiment, the unilateral gap is 0 - 0.5 mm.

[0038] As a specific implementation manner, the insert body further has a second insertion portion 423. The first insertion portion 422 is connected to the fixing block 421 through the second insertion portion 423, and the second insertion portion 423 is inserted into the installation hole 413 in an interference fit manner.

[0039] In this embodiment, the second insertion portion 423 of the insert body is also located in the installation hole 413, and the second insertion portion 423 and the installation hole 413 are in interference fit. Its main function is to fix the sliding fit portion 411 of the damping body 41, prevent the sliding fit portion 411 from skewing during the sliding process, and make its operation stable and reliable.

[0040] As a specific implementation manner, the outer peripheral side wall of the second insertion portion 423 is adapted to the inner surface of the installation hole 413.

[0041] In this embodiment, when the outer peripheral side wall of the second insertion portion 423 is adapted to the inner surface of the mounting hole 413, when the second insertion portion 423 is inserted into the mounting hole 413 in an interference fit manner, there is no gap between the outer peripheral side wall of the second insertion portion 423 and the inner surface of the mounting hole 413, so that the sliding fit portion 411 can be more firmly sleeved on the insert body.

[0042] As a specific implementation manner, the radial cross-section of the second insertion portion 423 is a first polygon, the radial cross-section of the mounting hole 413 is a second polygon, and the length difference between each side of the first polygon and each corresponding side of the second polygon is ΔL, where 0 < ΔL ≤ 1 mm; alternatively, the radial cross-section of the second insertion portion 423 is a first circle, the radial cross-section of the mounting hole 413 is a second circle, the diameter of the first circle is R1, the diameter of the second circle is R2, and 0 < R1 - R2 ≤ 1 mm.

[0043] In this embodiment, the interference fit between the second insertion portion 423 and the mounting hole 413 needs to be limited. Otherwise, it is not easy to sleeve the sliding fit portion 411 on the insert body, or even if it can be sleeved, the sliding fit portion 411 will be affected in its service life due to the large supporting force it bears. In this embodiment, the unilateral interference between the second insertion portion 423 and the mounting hole 413 is 0 - 0.5 mm. At the same time, when the radial cross-section of the second insertion portion 423 is a polygon, in order to prevent the corners of the polygon from applying too large a supporting force to the sliding fit portion 411 and damaging the sliding fit portion 411, the corners of the second insertion portion 423 also need to be rounded.

[0044] As a specific implementation manner, the sliding fit portion 411 has an outer circumferential side wall, the outer diameter of the sliding fit portion 411 is R, the moving track 3 is an arc track with a constant width, and the width of the moving track 3 is L, where 0 < R3 - L ≤ 1 mm.

[0045] In this embodiment, the sliding fit portion 411 is a hollow cylindrical structure, and the interference fit between the sliding fit portion 411 and the moving track 3 should also be limited. Otherwise, the sliding fit portion 411 cannot be installed into the moving track 3 of the bottom case 2, or even if it can be installed, a large frictional force will be generated during the sliding of the sliding fit portion 411 in the moving track 3, affecting the movement of the air deflector 1. Therefore, in this embodiment, the unilateral interference between the sliding fit portion 411 and the moving track 3 is 0 - 0.5 mm.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention. The above is only the preferred implementation manner of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present invention, several improvements and variations can still be made, and these improvements and variations should also be regarded as within the protection scope of the present invention.
