Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning equipment, and particularly to an air conditioner. Background Art

[0002] During the operation of an air conditioner, a driving mechanism is usually required to drive the air guiding blades to rotate to achieve left - right or up - down air sweeping, so as to increase the air outlet range.

[0003] The existing driving method for the air guiding blades is usually that a driving device drives a driving blade to rotate, and the driving blade drives other transmission blades to rotate, thereby realizing the turning of the air guiding blades. However, this structure of the air guiding blades is complex. Once the driving blade fails to rotate, all other transmission blades cannot rotate either, resulting in the failure of the air guiding blades. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an air conditioner which can drive all the air guiding blades to rotate relative to the air guiding door simultaneously.

[0005] The embodiment of the utility model is implemented as follows:

[0006] In a first aspect, the utility model provides an air conditioner, including a transmission shaft, an air guiding door, air guiding blades and a driving mechanism;

[0007] The number of the air guiding blades is multiple. The multiple air guiding blades are all connected to the transmission shaft. The multiple air guiding blades and the air guiding door are integrally formed. The driving mechanism is arranged on the air guiding door and connected to the transmission shaft. The transmission shaft is used to drive the multiple air guiding blades to rotate relative to the air guiding door simultaneously.

[0008] In the above - mentioned embodiment, by integrally forming the air guiding blades and the air guiding door, and connecting the transmission shaft to all the air guiding blades at the same time, it is ensured that the transmission shaft can drive all the air guiding blades to rotate relative to the air guiding door simultaneously under the driving action of the driving mechanism. Even if one of the air guiding blades is damaged, it will not affect the normal operation of other air guiding blades. Moreover, the integral formation of the air guiding blades and the air guiding door reduces the assembly process and assembly parts, which can effectively improve production efficiency and reduce production costs.

[0009] In an alternative embodiment, the air guiding blade includes a blade body, a first connecting portion and a second connecting portion. The first connecting portion and the second connecting portion are both connected to the blade body. The first connecting portion is connected to the transmission shaft, and the second connecting portion is connected to the air guiding door.

[0010] In the above embodiments, by setting the first connecting portion and the second connecting portion to be respectively connected to the transmission shaft, when the transmission shaft moves axially, certain deformations are generated in the first connecting portion and the second connecting portion, avoiding direct rigid connections between the transmission shaft and the blade body and between the blade body and the air deflector, thereby improving the service life of the air guiding blade.

[0011] In an alternative embodiment, a first through hole is formed in the middle position of the blade body, and the first through hole is used for the transmission shaft to pass through, and the first connecting portion extends into the first through hole and is connected to the transmission shaft.

[0012] In the above embodiments, by forming a first through hole in the middle position of the blade body, enabling the transmission shaft to pass through the first through hole and be connected to the first connecting portion, the transmission shaft is connected to the middle of the blade body.

[0013] In an alternative embodiment, the first connecting portion extends from the edge of the first through hole towards the middle of the first through hole.

[0014] In the above embodiments, one end of the first connecting portion is connected to the edge of the first through hole, and the other end extends towards the middle of the first through hole and is connected to the transmission shaft, so that the transmission shaft is located as much as possible at the central part of the first through hole, avoiding collision between the transmission shaft and the edge of the first through hole during the movement of the transmission shaft driving the blade body.

[0015] In an alternative embodiment, the second connecting portion extends in a direction away from the blade body from the edge of the blade body.

[0016] In the above embodiments, one end of the second connecting portion is connected to the edge of the blade body, and the other end is connected to the air deflector. Therefore, when the transmission shaft drives the blade body to move, certain deformation can be generated in the second connecting portion, thereby realizing the relative rotation of the blade body with respect to the air guiding blade.

[0017] In an alternative embodiment, the second connecting portion is inclined.

[0018] In the above embodiments, by arranging the second connecting portion to be inclined, the distance between the blade body and the air deflector can be made smaller, and the length of the second connecting portion can be made longer. That is, when the blade body is as close as possible to the air deflector, the connecting portion connecting the blade body and the air deflector is longer, thereby increasing the amount of deformation of the second connecting portion, ensuring that the blade body can effectively rotate relative to the air deflector under the drive of the transmission shaft, and avoiding breakage of the first connecting portion.

[0019] In an alternative embodiment, the blade body further has a second through hole, and the second through hole is located above the connection between the second connecting portion and the blade body.

[0020] In the above embodiments, by opening a second through hole above the second connecting portion, it is convenient for the blade body to deform under the drive of the transmission shaft.

[0021] In an alternative embodiment, the plurality of air guiding vanes are integrally formed with the transmission shaft.

[0022] In the above embodiments, the air guiding vanes and the air guiding door are integrally formed by a molding process, and the transmission shaft is connected to all the air guiding vanes at the same time, so as to ensure that the transmission shaft can drive all the air guiding vanes to rotate relative to the air guiding door under the drive of the driving mechanism. Even if one of the air guiding vanes is damaged, it will not affect the normal operation of other air guiding vanes; moreover, the integral formation of the air guiding vanes and the air guiding door reduces the assembly process and assembly parts, which can effectively improve production efficiency and reduce production costs.

[0023] In an alternative embodiment, the transmission shaft includes a transmission rod and a connecting rod. The transmission rod is connected to the plurality of air guiding vanes, the connecting rod is connected to the driving mechanism, and the transmission rod and the connecting rod are arranged at an angle.

[0024] In the above embodiments, by providing a transmission rod and a connecting rod connected at an angle, and through the transmission cooperation between the connecting rod and the driving mechanism, the transmission rod is connected to the plurality of air guiding vanes, so as to realize that under the drive of the driving mechanism, the connecting rod drives the transmission rod to axially move, and thereby drives the plurality of air guiding vanes to rotate relative to the air guiding door.

[0025] In an alternative embodiment, the connecting rod is provided with a sliding groove, the sliding groove extends along the length direction of the connecting rod, and the sliding groove is in transmission cooperation with the driving mechanism.

[0026] In the above embodiments, by the output end of the driving mechanism slidingly cooperating with the sliding groove, when the driving mechanism drives the transmission shaft, the transmission shaft can not only move along the axial direction, but also move along the extending direction of the sliding groove or generate a certain deformation, so as to increase the deformation range of the transmission shaft and the air guiding vanes, and can reduce the deformation of the air guiding vanes to a certain extent. This not only enables the air guiding vanes to rotate smoothly relative to the air guiding door, but also avoids breaking the air guiding vanes; since the connecting rod and the transmission rod are arranged at an angle, the extending direction of the sliding groove is also at an angle with the transmission rod. When the driving mechanism drives the transmission rod to axially move through the connecting rod, the transmission rod is also allowed to move along the extending direction of the sliding groove or generate a certain deformation relative to the output end of the driving mechanism, so as to enable the transmission shaft to drive the air guiding vanes to rotate relative to the air guiding door smoothly.

[0027] The beneficial effects of the air conditioner provided by the embodiment of the present utility model include: by making the air deflector blades and the air deflector door integrally formed, and enabling the transmission shaft to be connected to all the air deflector blades simultaneously, thereby ensuring that the transmission shaft can drive all the air deflector blades to rotate relative to the air deflector door under the driving action of the driving mechanism. Even if one of the air deflector blades is damaged, it will not affect the normal operation of other air deflector blades. Moreover, the integral forming of the air deflector blades and the air deflector door reduces the assembly process and assembly parts, which can effectively improve production efficiency and reduce production costs.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0040] During the operation of the air conditioner, a driving mechanism is usually required to drive the air deflector blades to rotate to achieve left - right or up - down air sweeping, thereby increasing the air outlet range.

[0041] The existing driving method of the air guiding vane usually drives the driving vane to rotate by a driving device, and drives other transmission vanes to rotate through the driving vane, so as to realize the turning of the air guiding vane. However, this structure of the air guiding vane is complex. Once the driving vane fails to rotate, all other transmission vanes cannot rotate either, resulting in the failure of the air guiding vane.

[0042] Based on the above problems, please refer to Figures 1 to 4 , an air conditioner 10 provided by an embodiment of the present invention includes a transmission shaft 100, an air guiding door 200, air guiding vanes 300 and a driving mechanism 400.

[0043] Wherein, a sliding groove 121 is arranged at one end of the transmission shaft 100, and the sliding groove 121 is used for driving cooperation with the driving mechanism 400. A plurality of air guiding vanes 300 are all connected with the transmission shaft 100, and the plurality of air guiding vanes 300 are also integrally formed with the air guiding door 200. The driving mechanism 400 is arranged on the air guiding door 200 and connected with the transmission shaft 100. The transmission shaft 100 is used for driving the plurality of air guiding vanes 300 to rotate relative to the air guiding door 200 simultaneously.

[0044] In this embodiment, the air guiding vane 300 and the air guiding door 200 are made by an integral forming process, and the transmission shaft 100 is connected with all the air guiding vanes 300 at the same time, so as to ensure that the transmission shaft 100 can drive all the air guiding vanes 300 to rotate relative to the air guiding door 200 under the driving action of the driving mechanism 400. Even if one of the air guiding vanes 300 is damaged, it will not affect the normal operation of other air guiding vanes 300. Moreover, the integral forming of the air guiding vane 300 and the air guiding door 200 reduces the assembly process and assembly parts, which can effectively improve the production efficiency and reduce the production cost.

[0045] It can be understood that the transmission shaft 100 moves along its own axial direction under the driving action of the driving mechanism 400. Since the air guiding vane 300, the air guiding door 200 and the transmission shaft 100 are integrally formed, the air guiding vane 300 can generate a certain deformation under the drive of the transmission shaft 100, so as to realize the rotation of the air guiding vane 300 relative to the air guiding door 200.

[0046] In addition, it should be noted that since the drive shaft 100 drives the air guiding blades 300 to generate a certain deformation to rotate relative to the air guiding door 200, and the force that generates the deformation also acts on the drive shaft 100. Therefore, by slidingly mating the output end of the drive mechanism 400 with the sliding groove 121, when the drive mechanism 400 drives the drive shaft 100, the drive shaft 100 can not only move along the axial direction, but also move along the extending direction of the sliding groove 121 or generate a certain deformation, so as to increase the deformation range of the drive shaft 100 and the air guiding blades 300, and can reduce the deformation of the air guiding blades 300 to a certain extent. This not only enables the air guiding blades 300 to rotate smoothly relative to the air guiding door 200, but also avoids damaging the air guiding blades 300.

[0047] Among them, multiple air guiding blades 300 are also integrally formed with the drive shaft 100. By using an integral forming process for the air guiding blades 300, the air guiding door 200 and the drive shaft 100, the drive shaft 100 is connected to all the air guiding blades 300 at the same time, so as to ensure that the drive shaft 100 can drive all the air guiding blades 300 to rotate relative to the air guiding door 200 at the same time. Even if one of the air guiding blades 300 is damaged, it will not affect the normal operation of other air guiding blades 300. Moreover, the integral forming of the air guiding blades 300, the air guiding door 200 and the drive shaft 100 reduces the assembly process and assembly parts, can effectively improve the production efficiency and reduce the production cost.

[0048] Furthermore, the air guiding blade 300 includes a blade body 310, a first connecting portion 320 and a second connecting portion 330. The first connecting portion 320 and the second connecting portion 330 are both connected to the blade body 310. The first connecting portion 320 is connected to the drive shaft 100, and the second connecting portion 330 is connected to the air guiding door 200.

[0049] In this embodiment, by setting the first connecting portion 320 and the second connecting portion 330 to be respectively connected to the drive shaft 100, when the drive shaft 100 moves axially, the first connecting portion 320 and the second connecting portion 330 generate a certain deformation, avoiding direct rigid connection between the drive shaft 100 and the blade body 310, and between the blade body 310 and the air guiding door 200, so as to improve the service life of the air guiding blade 300.

[0050] Furthermore, a first through hole 340 is formed in the middle position of the blade body 310. The first through hole 340 is used for the drive shaft 100 to pass through. The first connecting portion 320 extends into the first through hole 340 and is connected to the drive shaft 100.

[0051] In this embodiment, by forming the first through hole 340 in the middle position of the blade body 310, enabling the drive shaft 100 to pass through the first through hole 340 and be connected to the first connecting portion 320, the drive shaft 100 is connected to the middle of the blade body 310.

[0052] If the transmission shaft 100 is connected to the edge of the blade body 310, the position of the drive mechanism 400 connected to the transmission shaft 100 needs to be adjusted, which may cause the drive mechanism 400 to occupy a large space. Therefore, by connecting the transmission shaft 100 to the middle of the blade body 310, the drive device can be installed close to the air deflector 200, thereby effectively utilizing the space.

[0053] It is worth mentioning that setting the first through hole 340 at the middle position of the blade body 310 also facilitates mold opening.

[0054] It can be understood that the middle part of the blade body 310 can be the exact center position or a position close to the exact center, and no specific limitation is made here.

[0055] Furthermore, the first connecting portion 320 extends from the edge of the first through hole 340 towards the middle of the first through hole 340.

[0056] In this embodiment, one end of the first connecting portion 320 is connected to the edge of the first through hole 340, and the other end extends towards the middle of the first through hole 340 and is connected to the transmission shaft 100, so that the transmission shaft 100 is located as much as possible at the central part of the first through hole 340, avoiding collision between the transmission shaft 100 and the edge of the first through hole 340 during the movement of the transmission shaft 100 driving the blade body 310.

[0057] Furthermore, the second connecting portion 330 extends in a direction away from the blade body 310 from the edge of the blade body 310.

[0058] In this embodiment, one end of the second connecting portion 330 is connected to the edge of the blade body 310, and the other end is connected to the air deflector 200. Therefore, when the transmission shaft 100 drives the blade body 310 to move, the second connecting portion 330 can generate a certain deformation, thereby realizing the relative rotation of the blade body 310 with respect to the air deflector blade.

[0059] Furthermore, the second connecting portion 330 is inclined.

[0060] In this embodiment, by inclining the second connecting portion 330, the distance between the blade body 310 and the air deflector 200 can be made smaller, and the length of the second connecting portion 330 can be made longer. That is, when the blade body 310 is as close as possible to the air deflector 200, the connecting portion connecting the blade body 310 and the air deflector 200 is longer, thereby increasing the deformation amount of the second connecting portion 330, ensuring that the blade body 310 can effectively rotate relative to the air deflector 200 under the drive of the transmission shaft 100, and avoiding breakage of the first connecting portion 320.

[0061] It can be understood that the first connecting portion 320 and the second connecting portion 330 are in the same plane as the blade body 310.

[0062] Furthermore, the blade body 310 is further provided with a second through hole 350, and the second through hole 350 is located above the connection between the second connecting portion 330 and the blade body 310.

[0063] In this embodiment, by providing the second through hole 350 above the second connecting portion 330, it is convenient for the blade body 310 to deform under the drive of the transmission shaft 100.

[0064] Furthermore, the second through hole 350 extends in a direction away from the air deflector 200.

[0065] In this embodiment, by making the second through hole 350 extend in a direction away from the air deflector 200, that is, the hole area of the second through hole 350 is as large as possible, which is beneficial to the blade body 310 deforming under the drive of the transmission shaft 100.

[0066] Furthermore, the transmission shaft 100 includes a transmission rod 110 and a connecting rod 120. The transmission rod 110 is connected to a plurality of air guiding vanes 300. The transmission rod 110 and the connecting rod 120 are arranged at an angle. A sliding groove 121 is provided on the connecting rod 120.

[0067] In this embodiment, by providing the transmission rod 110 and the connecting rod 120 connected at an angle, providing the sliding groove 121 on the connecting rod 120, and slidingly matching the sliding groove 121 with the driving mechanism 400, the transmission rod 110 is connected to a plurality of air guiding vanes 300. In this way, under the drive of the driving mechanism 400, the transmission rod 110 is driven by the connecting rod 120 to axially move, and thereby drives a plurality of air guiding vanes 300 to rotate relative to the air deflector 200.

[0068] Optionally, the transmission rod 110 and the connecting rod 120 are arranged at 90°, that is, the transmission shaft 100 is in an L shape.

[0069] Furthermore, the sliding groove 121 extends along the length direction of the connecting rod 120.

[0070] In this embodiment, since the connecting rod 120 and the transmission rod 110 are arranged at an angle, the extending direction of the sliding groove 121 is also arranged at an angle with the transmission rod 110. When the driving mechanism 400 drives the transmission rod 110 to axially move through the connecting rod 120, it also allows the transmission rod 110 to move or deform to a certain extent relative to the output end of the driving mechanism 400 along the extending direction of the sliding groove 121, so that the transmission shaft 100 can smoothly drive the air guiding vanes 300 to rotate relative to the air deflector 200.

[0071] In summary, the present utility model provides an air conditioner 10. By integrally molding the air guide vanes 300, the air guide door 200, and the transmission shaft 100, the transmission shaft 100 is simultaneously connected to all the air guide vanes 300, ensuring that the transmission shaft 100 can drive all the air guide vanes 300 to rotate relative to the air guide door 200. Even if one of the air guide vanes 300 is damaged, it will not affect the normal operation of the other air guide vanes 300. Moreover, the integral molding of the air guide vanes 300, the air guide door 200, and the transmission shaft 100 reduces the assembly processes and assembly parts, effectively improving production efficiency and reducing production costs. In addition, by the sliding fit of the output end of the driving mechanism 400 with the sliding groove 121, when the driving mechanism 400 drives the transmission shaft 100, the transmission shaft 100 can not only move along the axial direction but also move along the extension direction of the sliding groove 121 or generate a certain deformation, thereby increasing the deformation range of the transmission shaft 100 and the air guide vanes 300 and reducing the deformation of the air guide vanes 300 to a certain extent. This not only enables the air guide vanes 300 to rotate smoothly relative to the air guide door 200 but also avoids damaging the air guide vanes 300.

[0072] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
