Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and more particularly to a wind guiding component and an air conditioner. Background Art

[0002] Some air conditioners are equipped with a wind guiding component, which usually consists of a wind guiding plate and sweeping blades. The wind guiding plate flips up and down at the air outlet under the drive of a drive module to achieve up and down air guiding; a plurality of sweeping blades are arranged in sequence on the wind guiding plate and swing left and right under the drive of the drive module to achieve left and right air sweeping.

[0003] In the currently available wind guiding components on the market, a complex intermediate mechanism is usually adopted for transmission connection between the drive module and a plurality of sweeping blades, resulting in a complex overall structure of the wind guiding component, difficult disassembly and assembly, and high cost. Summary of the Utility Model

[0004] The problem solved by the utility model is that the wind guiding component configured in the existing air conditioner has a complex structure, difficult disassembly and assembly, and high cost.

[0005] To solve the above problems, the utility model provides a wind guiding component, which has the characteristics of simple structure, easy disassembly and assembly, and lower cost.

[0006] An embodiment of the utility model provides a technical solution:

[0007] A wind guiding component includes a wind guiding plate, a drive module, an intermediate rack, a sweeping module and a driven gear. The drive module is connected to the intermediate rack, and the sweeping module is arranged on the wind guiding plate and connected to the driven gear;

[0008] The intermediate rack meshes with the driven gear. The intermediate rack is used to drive the driven gear to rotate under the drive of the drive module, so as to drive the sweeping module to act relative to the wind guiding plate.

[0009] For the wind guiding component provided by the embodiment of the utility model, a combination of a rack and a gear is configured between the drive module and the sweeping module. The drive module drives the intermediate rack to move linearly, and the intermediate rack drives the engaged driven gear to rotate, so as to drive the sweeping module to act relative to the wind guiding plate to achieve air sweeping. Therefore, the wind guiding component provided by the embodiment of the utility model has the characteristics of simple structure, easy disassembly and assembly, and lower cost.

[0010] In an optional embodiment, the sweeping module includes a driving blade, a linkage and a driven blade. The driving blade and the driven blade are respectively connected to the wind guiding plate. The driving blade is connected to the driven blade through the linkage, and the driven gear is connected to the driving blade.

[0011] The driving module drives the driving blade to swing through the intermediate rack and the driven gear. The driving blade drives the driven blade to swing synchronously through the linkage, realizing air sweeping.

[0012] In an alternative embodiment, the driven gear is integrally formed with the driving blade.

[0013] The integral formation of the driven gear and the driving blade reduces the production cost and the difficulty of disassembly and assembly.

[0014] In an alternative embodiment, the driving blade has a rotating portion and a driving portion arranged at intervals in a direction parallel to the air guide plate. The rotating portion is rotatably connected to the air guide plate. The driven gear is connected to the rotating portion and is coaxially arranged therewith. The driving portion is connected to the driven blade through the linkage.

[0015] The driving blade rotates around the rotating portion. The driven gear is coaxially connected to the rotating portion. The movement of the driven gear is not affected by the rotation of the driving blade, ensuring the accuracy of the air sweeping angle.

[0016] In an alternative embodiment, a guide rail and an installation cavity are provided on one side surface of the air guide plate. The installation cavity is on one side of the guide rail and communicates with the guide rail. The driven gear is located in the installation cavity, and the intermediate rack is located in the guide rail and is in sliding fit with the guide rail.

[0017] The intermediate rack slides along the guide rail under the drive of the driving module, thereby driving the driven gear located in the installation cavity communicating with the guide rail to rotate, ensuring the accuracy and efficiency of power transmission.

[0018] In an alternative embodiment, the driving blade has a rotating portion, a connecting portion and a driving portion arranged in sequence in a direction parallel to the plane where the air guide plate is located. The rotating portion is rotatably connected to the air guide plate. The driving portion is connected to the linkage, and the connecting portion is connected to the driven gear.

[0019] The connecting portion is between the rotating portion and the driving portion. The distance between the connecting portion and the rotating portion is less than the distance between the driving portion and the rotating portion, so that the action of the driving module is amplified, thereby reducing the movement stroke of the driving module and the intermediate rack.

[0020] In an alternative embodiment, the intermediate rack has a shallow tooth portion. The shallow tooth portion is between the two ends of the intermediate rack. From the shallow tooth portion to any one end of the intermediate rack, the depths of a plurality of sequentially arranged tooth grooves gradually increase.

[0021] The driving blade meshes with the shallow tooth part of the intermediate rack in the initial state. As the swinging angle of the driving blade increases, the driven gear will gradually move away from the intermediate rack. Since the tooth groove depth gradually increases from the shallow tooth part to any end of the intermediate rack, it can ensure that the driven gear and the intermediate rack always maintain reliable meshing, ensuring the stable and reliable adjustment of the air-sweeping function.

[0022] In an alternative embodiment, the side of the intermediate rack that meshes with the driven gear is concave arc-shaped.

[0023] As the swinging angle of the driving blade increases, the driven gear will gradually move away from the intermediate rack. Since the side of the intermediate rack that meshes with the driven gear is concave arc-shaped, it can ensure that the driven gear and the intermediate rack always maintain reliable meshing, ensuring the stable and reliable adjustment of the air-sweeping function.

[0024] In an alternative embodiment, the driving module includes a driving member and a driving gear. The driving member is disposed on the air deflector and connected to the driving gear. The driving member is used to drive the driving gear to rotate self, and the driving gear meshes with the intermediate rack.

[0025] The driving member can be a motor. The rotating shaft of the motor drives the driving gear to rotate self, the driving gear then drives the intermediate rack to move linearly, and the intermediate rack drives the driven gear to rotate, thereby driving the driving blade and the driven blade to swing, realizing the adjustment of the air-sweeping function.

[0026] An embodiment of the present invention further provides an air conditioner, including a machine body and the aforementioned air guiding assembly. The air guiding assembly includes an air deflector, a driving module, an intermediate rack, an air-sweeping module and a driven gear. The driving module is connected to the intermediate rack. The air-sweeping module is disposed on the air deflector and connected to the driven gear. The intermediate rack meshes with the driven gear. The intermediate rack is used to drive the driven gear to rotate under the drive of the driving module, thereby driving the air-sweeping module to act relative to the air deflector. The machine body has an air outlet, and a plurality of the air guiding assemblies are all installed at the air outlet.

[0027] For the air conditioner provided by the embodiment of the present invention, a plurality of air guiding assemblies are installed in the air outlet, realizing the zoning adjustment of the air output from the air outlet, with richer adjustment functions and better user experience. Moreover, benefiting from the beneficial effects of the air guiding assembly, the air conditioner also has the characteristics of simple structure, easy disassembly and assembly, and lower cost.

Detailed implementation manners

[0033] To make the above objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model is given with reference to the accompanying drawings.

[0034] Please refer to Figure 1 , Figure 1 which shows a schematic structural view of the air conditioner 10 provided in this embodiment.

[0035] The air conditioner 10 provided in this embodiment includes a body 11 and a plurality of air guiding assemblies 100. The body 11 has an air outlet 12, and the plurality of air guiding assemblies 100 are all installed at the air outlet 12.

[0036] The air guiding assembly 100 can not only adjust the angle of the air flow blown out from the air outlet 12 in the vertical direction, that is, up and down air guiding, but also adjust the angle in the horizontal direction, that is, left and right air sweeping. The plurality of air guiding assemblies 100 are arranged at different positions of the air outlet 12 to realize the regional adjustment of the air outlet angle of the air outlet 12.

[0037] Specifically, in this embodiment, the number of the air guiding assemblies 100 is two, and the two air guiding assemblies 100 are arranged in sequence in the length direction of the air outlet 12 to realize the independent adjustment of the air outlet conditions in the left and right regions of the air outlet 12.

[0038] Please refer to Figure 2 and Figure 3 , Figure 2 which shows a partial structural view of the air guiding assembly 100 provided in this embodiment, Figure 3 which shows Figure 2 an enlarged schematic view of area A in

[0039] The wind guide assembly 100 provided in this embodiment includes a wind guide plate 110, a driving module, an intermediate rack 130, a wind sweeping module 140 and a driven gear 150. The driving module is connected to the intermediate rack 130. The wind sweeping module 140 is arranged on the wind guide plate 110 and connected to the driven gear 150. The intermediate rack 130 is meshed with the driven gear 150. The intermediate rack 130 is used to drive the driven gear 150 to rotate under the drive of the driving module, thereby driving the wind sweeping module 140 to move relative to the wind guide plate 110 to achieve left and right wind sweeping.

[0040] In actual application, the air guide plate 110 rotates in a vertical plane to adjust the vertical air outlet angle. The driving module drives the driven gear 150 to rotate through the intermediate rack 130, thereby driving the wind sweeping module 140 to move relative to the air guide plate 110 to adjust the horizontal air outlet angle.

[0041] In this embodiment, the driving module may include a driving member and a driving gear 121 . The driving member is disposed on the air guide plate 110 and connected to the driving gear 121 . The driving member is used to drive the driving gear 121 to rotate. The driving gear 121 is meshed with the intermediate rack 130 .

[0042] The driving member can be a motor, and the driving gear 121 is sleeved on the rotating shaft of the motor. When the motor is running, the rotating shaft rotates, driving the driving gear 121 to rotate, and the driving gear 121 drives the intermediate rack 130 to reciprocate in a linear direction, and the intermediate rack 130 drives the driven gear 150 to rotate, thereby driving the air sweeping module 140 to sweep the air.

[0043] Specifically, in this embodiment, the wind sweeping module 140 includes a driving blade 141, a linkage 142 and a driven blade 143. The driving blade 141 and the driven blade 143 are respectively connected to the wind guide plate 110. The driving blade 141 is connected to the driven blade 143 through the linkage 142, and the driven gear 150 is connected to the driving blade 141.

[0044] In this embodiment, the driving blade 141 is rotatably connected to the air guide plate 110, and the driven blade 143 is fixedly connected to the air guide plate 110. That is, the driving blade 141 rotates relative to the air guide plate 110 under the drive of the driven gear 150, and drives the driven blade 143 to deform and swing through the linkage 142.

[0045] The air guide plate 110 may be a single-layer structure or a multi-layer composite structure. In this embodiment, the length direction of the air guide plate 110 is parallel to the length direction of the air outlet 12, and the air guide plate 110 may also be connected to the driving module in a transmission manner. In practical applications, the driving module drives the air guide plate 110 to flip up and down at the air outlet 12 to adjust the air outlet angle in the vertical direction.

[0046] The driving member and the driving gear 121 of the driving module drive the driving blade 141 to rotate horizontally through the intermediate rack 130, and the driving blade 141 drives the driven blade 143 to swing horizontally synchronously through the linkage member 142, thereby adjusting the air outlet angle in the horizontal direction, that is, adjusting the wind sweeping angle.

[0047] In fact, there are multiple driven blades 143. Since the driving blade 141 is rotatably connected to the wind guide plate 110, the rotation angle is guaranteed to be in place, thereby ensuring that the wind sweeping action and wind sweeping angle of the multiple driven blades 143 are standard and in place, and a better wind sweeping effect is obtained. The multiple driven blades 143 are fixed on the wind guide plate 110, omitting a large number of component combinations, and the structure is simple and easy to disassemble and assemble, and the structural stability is better.

[0048] In order to further reduce the difficulty of assembling the air guide assembly 100 , in this embodiment, the driving blade 141 is detachably and rotatably connected to the air guide plate 110 , the driven gear 150 and the driving blade 141 are integrally formed, and the linkage 142 and the plurality of driven blades 143 are integrally formed with the air guide plate 110 .

[0049] In this embodiment, the driving blade 141 and the plurality of driven blades 143 are sequentially arranged in intervals along a first direction. Figure 2 In the direction indicated by the X arrow, the plurality of driven blades 143 are connected to the driving blade 141 through the linkage member 142 , and the linkage member 142 extends along the first direction.

[0050] The driving module is arranged on the side of the driving blade 141 away from the multiple driven blades 143, and the intermediate rack 130 also telescopes in the first direction, where the first direction is the length extension direction of the air guide plate 110. The driving blade 141 and the multiple driven blades 143 are arranged in sequence on the same side of the air guide plate 110 along the length extension direction of the air guide plate 110, thereby maximizing the utilization of the surface space of the air guide plate 110. When the driving blade 141 and the multiple driven blades 143 swing in the first direction, the horizontal air outlet angle of the air outlet 12 can be adjusted quickly and efficiently.

[0051] Taking into account that in actual applications, when the driving blade 141 rotates, the force applied to the linkage 142 actually forms an angle with the first direction. In order to avoid deflection of the linkage 142, which results in inconsistent swinging degrees of multiple driven blades 143, in this embodiment, the driving blade 141 and the linkage 142 are connected in a detachable and rotatable manner.

[0052] In this embodiment, the driving blade 141 has a rotating part 1411 and a driving part 1412 arranged at intervals in a direction parallel to the air deflector 110. The rotating part 1411 is rotatably connected to the air deflector 110. The driven gear 150 is connected to the rotating part 1411 and coaxially arranged. The driving part 1412 is connected to the driven blade 143 through a linkage 142.

[0053] When the driving blade 141 rotates relative to the air deflector 110, its rotation center line is the axis of the rotating part 1411. Since the driven gear 150 is coaxially arranged with the rotating part 1411, during the linear movement of the intermediate rack 130 in the first direction, the driven gear 150 only rotates on its own axis, and the distance between it and the intermediate rack 130 does not change. The driving blade 141 can rotate smoothly, thereby driving multiple driven blades 143 to swing smoothly, ensuring the smoothness of the air-sweeping adjustment process.

[0054] To further improve the stability of the air-sweeping adjustment process, in this embodiment, a guide rail 111 and an installation cavity 112 are provided on one side surface of the air deflector 110. The installation cavity 112 is located on one side of the guide rail 111 and communicates with the guide rail 111. The driven gear 150 is located in the installation cavity 112, and the intermediate rack 130 is located in the guide rail 111 and is slidably engaged with the guide rail 111.

[0055] It can be understood that the guide rail 111 extends in the first direction. When the intermediate rack 130 is installed in the guide rail 111 and the driven gear 150 is installed in the installation cavity 112, the intermediate rack 130 and the driven gear 150 remain meshed. In practical applications, when the driving member drives the driving gear 121 to rotate, the intermediate rack 130 linearly slides along the guide rail 111 under the drive of the driving gear 121. During the sliding process, the driven gear 150 rotates on the surface of the air deflector 110, thereby driving the driving blade 141 to rotate around the rotating part 1411.

[0056] In another embodiment, a connecting part can also be provided between the rotating part 1411 and the driving part 1412 on the driving blade 141. The rotating part 1411 is also rotatably connected to the air deflector 110, and the driving part 1412 is also connected to the linkage 142. The difference is that in this embodiment, the driven gear 150 is connected to the connecting part.

[0057] In this embodiment, when the driving gear 121 of the driving module rotates, the intermediate rack 130 also linearly moves in the first direction. During this process, the driven gear 150 is driven to rotate, thereby driving the driving blade 141 to rotate relative to the air deflector 110 with the rotating part 1411 as the center.

[0058] It can be understood that the distance between the connecting portion and the rotating portion 1411 is less than the distance between the connecting portion and the driving portion 1412. The movement stroke of the connecting portion is much smaller than the movement stroke of the driving portion 1412, greatly reducing the linear movement stroke of the driving module and the intermediate rack 130. Moreover, compared with the connecting portion, the driving portion 1412, which is farther away from the rotating portion 1411, is connected to the linkage member 142. The driving portion 1412 drives the driven blade 143 to swing through the linkage member 142, reducing the driving force of the driving module.

[0059] In order to increase the lever arm length of the driven blade 143 and further reduce the driving force, in this embodiment, one end of each of the plurality of driven blades 143 corresponding to the driving portion 1412 of the driving blade 141 in the first direction is connected to the linkage member 142. In order to further optimize the driving torque, in this embodiment, the connecting portion of the driving blade 141 and the positions where the plurality of driven blades 143 are respectively connected to the air guide plate 110 are aligned in the first direction.

[0060] It can be understood that since one end of each of the plurality of driven blades 143 corresponding to the driving portion 1412 of the driving blade 141 in the first direction is connected to the linkage member 142, and the positions where the plurality of driven blades 143 are connected to the air guide plate 110 are aligned with the connecting portion of the driving blade 141 in the first direction, the lever arm of the driven blade 143 is maximized, greatly reducing the driving force.

[0061] Although it results in the largest movement stroke of the linkage member 142, the intermediate rack 130 meshes with the driven gear 150 connected to the connecting portion of the driving blade 141, and the connecting portion is closer to the rotating portion 1411, that is, the movement stroke of the driving module and the intermediate rack 130 in the first direction is smaller and is not affected by the movement stroke of the linkage member 142.

[0062] It can be seen that the air guide assembly 100 provided in this embodiment can reduce the driving force of the driving module and at the same time reduce the driving stroke of the driving module, obtaining a larger installable area for the driving blade 141 and the driven blade 143 on the air guide plate 110, thereby obtaining a better air-sweeping effect.

[0063] Considering that in this embodiment, when the driving blade 141 rotates, due to the eccentric setting between the connecting portion and the rotating portion 1411, that is, the driven gear 150 is eccentrically arranged with respect to the rotating portion 1411, the driven gear 150 will be driven by the driving blade 141 to deflect by a certain angle, thus gradually moving away from the intermediate rack 130.

[0064] In order to ensure that the intermediate rack 130 can always maintain stable meshing with the driven gear 150, in this embodiment, the intermediate rack 130 has a shallow tooth portion, which is located between the two ends of the intermediate rack 130. From the shallow tooth portion to any one end of the intermediate rack 130, the depths of a plurality of sequentially arranged tooth grooves gradually increase.

[0065] The driving blade 141 meshes with the shallow tooth portion of the intermediate rack 130 in the initial state. As the swing angle of the driving blade 141 increases, the driven gear 150 will gradually move away from the intermediate rack 130. Since the depth of the tooth groove gradually increases from the shallow tooth portion to any one end of the intermediate rack 130, it can ensure that the driven gear 150 and the intermediate rack 130 always maintain reliable meshing, ensuring the stable and reliable adjustment of the air-sweeping.

[0066] In another embodiment, the depths of the plurality of tooth grooves of the intermediate rack 130 can also be kept consistent, and the side of the intermediate rack 130 meshing with the driven gear 150 is set to be concave arc-shaped. Since the side of the intermediate rack 130 meshing with the driven gear 150 is concave arc-shaped, it can compensate for the stroke of the driven gear 150 moving away from the intermediate rack 130 during the swing of the driving blade 141, so as to ensure that the driven gear 150 and the intermediate rack 130 always maintain reliable meshing, ensuring the stable and reliable adjustment of the air-sweeping.

[0067] In summary, the air guide assembly 100 provided by the present application has the characteristics of simple structure, easy disassembly and assembly, and lower cost. The air conditioner 10 provided by this embodiment realizes the zoning adjustment of the air outlet from the air outlet 12, with richer adjustment functions and better user experience.

[0068] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention should be subject to the scope defined by the claims.
