Abstract
Description
Technical Field
[0001] This invention relates to the field of air conditioning product technology, specifically to an air guide plate assembly and an air conditioner. Background Technology
[0002] Air conditioners are generally equipped with air deflector assemblies to guide airflow. In practice, to obtain different airflow experiences, they include air deflectors and air sweeping vanes. At least one end of the air deflector is rotatably connected to the air conditioner casing, so that the rotation of the air deflector can control the opening of the air outlet and the direction of airflow. The air sweeping vanes are installed on the air deflector and can swing left and right under the drive module to achieve left and right air sweeping.
[0003] The existing technology has the following technical problems: the air guide plate and the sweeping blades are independent components, which require connecting parts and drive mechanisms. Therefore, there are many parts used, resulting in low assembly efficiency and high product cost.
[0004] Chinese Patent CN223106164U addresses the technical problems of complex transmission mechanisms, difficult disassembly and assembly, and high costs in the prior art between the drive module and multiple sweeping blades, and discloses an air guide assembly and an air conditioner. Specifically, it includes an air guide 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 disposed on the air guide plate and connected to the driven gear. The intermediate rack meshes with the driven gear, and the intermediate rack is used to drive the driven gear to rotate under the drive of the drive module, thereby causing the sweeping module to move relative to the air guide plate.
[0005] The aforementioned patent primarily addresses the complex transmission issue between the drive module and multiple sweeping blades. Multiple sweeping blades and the air guide plate still require assembly and connection, resulting in low assembly efficiency. Furthermore, in existing technologies, the drive module for the sweeping blades is located on the air guide plate. In practice, the drive module must rotate with the air guide plate, increasing the required assembly space. Additionally, due to component movement requirements, wiring harnesses are difficult to arrange and control, reducing reliability. Moreover, the air guide plate's main function is to guide airflow to the air outlet of the air conditioner; placing the drive module here affects airflow uniformity and volume, and may also cause noise. The drive module can also cause uneven mass distribution within the air guide plate. Summary of the Invention
[0006] To overcome the technical problem of low assembly efficiency of existing air guide plate assemblies, the present invention provides an air guide plate assembly and an air conditioner.
[0007] The technical solution adopted by this invention to solve its technical problem is: The air guide plate assembly includes an air guide plate and multiple air guide vanes, which are integrated with the air guide plate. The multiple air guide vanes are spaced apart along the length of the air guide plate. It also includes a connecting rod and a drive mechanism assembly. The length of the connecting rod is consistent with the length of the air guide plate. One end of the air guide vane is connected to the air guide plate, and the other end is connected to the connecting rod. The drive mechanism assembly is used to drive the connecting rod to perform reciprocating linear motion along the length direction. The air guide vanes have a certain degree of flexibility, so that when the connecting rod moves linearly along the length direction, it can drive the air guide vanes to move, thereby achieving air sweeping.
[0008] In this application, by configuring the air guide vanes and air guide plates into an integrated structure, the number of parts is reduced and assembly is facilitated. Multiple air guide vanes are connected to one end by a connecting rod, thereby driving multiple air guide vanes to deflect synchronously to achieve air sweeping. The structure is simple, low in cost and easy to assemble.
[0009] In some embodiments, the connecting rod is used to connect one end of the drive mechanism assembly that extends relative to the air guide plate, and the drive mechanism assembly is connected to the outside of the air guide plate during use.
[0010] In some embodiments, the drive mechanism assembly includes a drive gear, a rack, and a movable block. The rack extends in the same direction as the length of the connecting rod. The movable block is fixedly connected to the rack, so that the drive gear can drive the rack and the movable block to move linearly. The end of the connecting rod that extends relative to the air guide plate is connected to the movable block, so that the movement of the movable block can pull the connecting rod to move linearly.
[0011] In some embodiments, a bushing is also included. A limiting groove is provided on the movable block. When in use, the bushing is located in the limiting groove. The end of the connecting rod that extends relative to the air guide plate is connected to the bushing, so that the movable block moves to drive the bushing, which in turn drives the connecting rod to make linear motion. The size of the limiting groove is larger than that of the bushing, so that the bushing can move in the limiting groove, so that when the drive mechanism assembly does not move synchronously with the air guide plate, it can meet the clearance requirements when both the air guide vanes and the air guide plate move.
[0012] In some embodiments, the bushing is made of a self-lubricating material.
[0013] In some embodiments, the connecting rod and the bushing are separate. The end of the connecting rod that extends out of the air guide plate is provided with a buckle. The buckle can deform inward to facilitate the assembly of the connecting rod and the bushing. The bushing limits the connecting rod in both the front and rear directions along the length of the connecting rod, so as to drive the connecting rod to make linear motion.
[0014] In some embodiments, a clearance notch is provided on the wall of the air guide plate at the end of the connecting rod that extends out of the air guide plate, so as to meet the clearance requirements when both the air guide vanes and the air guide plate are in motion.
[0015] In some embodiments, one end of the air guide plate is used to connect to the first stepper motor that drives the air guide plate to rotate, and the end of the connecting rod that extends relative to the air guide plate is located at the other end of the air guide plate.
[0016] In some embodiments, when the air guide vanes are not deformed, the axis of the connecting rod coincides with the axis of rotation of the air guide plate.
[0017] The present invention also provides an air conditioner, comprising a housing, a heat exchanger and a fan assembly, and an air guide plate assembly. The housing has an air inlet and an air outlet, and an air duct is formed between the air inlet and the air outlet. The heat exchanger and the fan assembly are disposed in the air duct, and the air guide plate assembly is located at the air outlet. The air guide plate assembly is the air guide plate assembly as described in any of the above embodiments.
[0018] The beneficial effects of this invention are: By configuring the air guide vanes and air guide plates into an integrated structure, the number of parts is reduced, and assembly is facilitated. Multiple air guide vanes are connected to one end using connecting rods, thereby driving multiple air guide vanes to deflect synchronously to achieve air sweeping. The structure is simple, low-cost, and easy to assemble. Attached Figure Description

Detailed Implementation
[0021] The invention will be further described below with reference to the accompanying drawings.
[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0023] like Figures 1-10 As shown, the present invention provides an air guide plate assembly and an air conditioner.
[0024] Reference Figures 1-3 As shown, the air conditioner 1 includes a casing, a heat exchanger and a fan assembly 4, and an air guide plate assembly. The casing has an air inlet and an air outlet, and an air duct is formed between the air inlet and the air outlet. The heat exchanger and the fan assembly 4 are arranged in the air duct, and the air guide plate assembly is located at the air outlet.
[0025] Reference Figure 6 and Figure 8 As shown, the air guide plate assembly includes an air guide plate 2 and multiple air guide vanes 14. The air guide vanes 14 and the air guide plate 2 are an integral structure, and the multiple air guide vanes 14 are spaced apart along the length of the air guide plate 2. It also includes a connecting rod 15 and a drive mechanism group 5. The length of the connecting rod 15 is consistent with the length of the air guide plate 2. One end of the air guide vane 14 is connected to the air guide plate 2, and the other end is connected to the connecting rod 15. The drive mechanism group 5 is used to drive the connecting rod 15 to perform reciprocating linear motion along the length direction. The air guide vanes 14 have a certain degree of flexibility, so that when the connecting rod 15 moves linearly along the length direction, it can drive the air guide vanes 14 to move, thereby achieving air sweeping.
[0026] In this application, by configuring the air guide vanes 14 and the air guide plate 2 as an integrated structure, the number of parts is reduced and assembly is facilitated. Multiple air guide vanes 14 are connected to one end by a connecting rod 15, thereby driving multiple air guide vanes 14 to deflect synchronously to achieve air sweeping. The structure is simple, low in cost and easy to assemble.
[0027] correspond Figure 8 of, Figure 9 and Figure 10 The diagram shows the state of the connecting rod 15 moving along its length, which drives the air guide vane 14 to move.
[0028] Conventionally, the air guide vane 14 can be made of flexible PP material or similar materials. When the air guide vane 14 is not deformed, its large surface is perpendicular to the air guide plate 2. The air guide plate 2 has a driving component on at least one side along its length, thereby rotating the air guide plate 2 to achieve vertical airflow at the air outlet, while the movement of the air guide vane 14 can achieve horizontal airflow at the air outlet. Figure 9 This demonstrates the state of the wind vane 14 when it is not deformed. Figure 10 The illustration shows the state in which the air guide vane 14 deflects to one side under the pull of the connecting rod 15. In this embodiment, thinning areas 18 are provided in both the root region of the air guide vane 14 connected to the air guide plate 2 and the top region of the connecting rod 15 to reduce the rebound plastic force of the vane.
[0029] The air guide plate 2 and air guide vane 14 here can also be achieved through integrated injection molding or dual injection molding, making the components integrated and improving production efficiency.
[0030] Based on the aforementioned integrated structure of the air guide vane 14 and the air guide plate 2, this application addresses a series of problems arising from the existing technology where the drive mechanism assembly is located on the air guide plate 2. For example, the required assembly space increases, and the wiring harness is more difficult to arrange and control due to component movement requirements, reducing reliability. Furthermore, since the main function of the air guide plate 2 is to guide airflow to the air outlet of the air conditioner 1, placing the drive module here would affect the uniformity and volume of airflow, potentially causing noise, and the drive module would also result in uneven mass distribution of the air guide plate 2. This application further optimizes the connection position of the drive mechanism assembly 5.
[0031] Combination Figure 6 and Figure 7 As shown, in this embodiment, the connecting rod 15 is used to connect one end of the drive mechanism assembly 5, which extends relative to the air guide plate 2. When in use, the drive mechanism assembly 5 is connected to the outside of the air guide plate 2.
[0032] As described above, based on this application, multiple air guide vanes 14 are synchronously controlled by connecting rod 15, and the drive mechanism group 5 that drives the connecting rod 15 is set outside the air guide plate 2.
[0033] like Figures 3-5 As shown, in this embodiment, the drive mechanism group 5 includes a drive gear 8, a rack 10, and a moving block 11. The rack 10 extends in the same direction as the length of the connecting rod 15. The moving block 11 is fixedly connected to the rack 10, so that the drive gear 8 can move and drive the rack 10 and the moving block 11 to move linearly. The end of the connecting rod 15 that extends relative to the air guide plate 2 is connected to the moving block 11, so that the movement of the moving block 11 can pull the connecting rod 15 to move linearly.
[0034] The drive mechanism assembly 5 here also includes a mounting box 13 for new protection of internal components.
[0035] Furthermore, it also includes a bushing 9, and a limiting slot 12 is configured on the moving block 11. When in use, the bushing 9 is located in the limiting slot 12. The end of the connecting rod 15 that extends relative to the air guide plate 2 is connected to the bushing 9, so that the moving block 11 moves to drive the bushing 9, and then drives the connecting rod 15 to make linear motion. The limiting slot 12 is larger than the bushing 9, and the bushing 9 can move in the limiting slot 12, so that when the drive mechanism group 5 does not move synchronously with the air guide plate 2, it can meet the clearance requirements when both the air guide vane 14 and the air guide plate 2 are moving.
[0036] The connection between the end of the connecting rod 15 extending relative to the air guide plate 2 and the bushing 9 includes at least the following three cases: 1. The connecting rod 15 and the bushing 9 are separate, and the bushing 9 limits the connecting rod 15 in both the front and rear directions along its length, thereby driving the connecting rod 15 to move back and forth. The bushing 9 only limits the front and rear movement of the connecting rod 15 and does not restrict its rotation; 2. The connecting rod 15 and the bushing 9 are separate but fixedly connected. The bushing 9 not only restricts the front and rear movement of the connecting rod 15, but also rotates synchronously with the connecting rod 15; 3. The connecting rod 15 and the bushing 9 are integrated.
[0037] Preferably, in this embodiment, the drive mechanism assembly 5 is not connected to the air guide plate 2 to further optimize the structural layout and avoid uneven mass distribution of the air guide plate 2, which could negatively impact product reliability. Therefore, the drive mechanism assembly 5 is preferably fixed to the housing of the air conditioner 1, which in this case is the bottom frame 3. The clearance requirement of the limiting slot 12 for the bushing 9 is based on the fact that the connecting rod 15 has both linear movement in the length direction and rotation with the air guide plate 2. In this embodiment, this is manifested in that the diameter of the limiting slot 12 is larger than the outer diameter of the bushing 9, thereby reserving radial movement space.
[0038] In this embodiment, the bushing 9 is made of a self-lubricating material. This reduces friction and facilitates the movement of the bushing 9 within the retaining groove 12. For materials such as POM, friction can also be reduced by adding lubricating oil.
[0039] like Figure 7 As shown, in this embodiment, the preferred connection form of the bushing 9 and the connecting rod 15 is the first case mentioned above. The connecting rod 15 and the bushing 9 are set separately. The end of the connecting rod 15 that extends relative to the air guide plate 2 is provided with a buckle 17. The buckle 17 can deform inward to facilitate the assembly of the connecting rod 15 and the bushing 9. The bushing 9 limits the connecting rod 15 in both the front and rear directions along the length of the connecting rod 15 so as to drive the connecting rod 15 to make linear movement.
[0040] The buckle 17 is used here to facilitate the assembly of the connecting rod 15 and the bushing 9. The bushing 9 limits the connecting rod 15 in both the front and rear directions along the length of the connecting rod 15, which can be achieved by forming a groove on the connecting rod 15. In this embodiment, one side of the groove is the buckle 17.
[0041] like Figure 7 As shown, in this embodiment, a clearance notch 16 is provided on the wall of the air guide plate 2 at the end of the connecting rod 15 extending from the air guide plate 2, so as to meet the clearance requirements when both the air guide vane 14 and the air guide plate 2 are in motion.
[0042] Similarly, the clearance requirement here is for the wall of the air guide plate 2 to make way for the connecting rod 15, so as to realize the interconnection between the rotation of the air guide plate 2 and the deflection angle of the blades, and avoid torque.
[0043] Reference Figure 2 and Figure 3 As shown, in this embodiment, one end of the air guide plate 2 is used to connect to the first stepper motor 6 that drives the air guide plate 2 to rotate, and the end of the connecting rod 15 that extends relative to the air guide plate 2 is located at the other end of the air guide plate 2. In this embodiment, the second stepper motor 7 drives the drive gear 8.
[0044] Furthermore, when the air guide vane 14 does not deform, the axis of the connecting rod 15 coincides with the axis of rotation of the air guide plate 2.
[0045] The above settings reduce the clearance required when the air guide plate 2 rotates and the connecting rod 15 moves.
[0046] In summary, the integrated structure of the air guide plate 2 and air guide vanes 14 provided in this application, combined with the drive mechanism assembly 5, separates the rotation of the air guide plate 2 and the air guide vanes 14. This allows multiple components to function using a single part, reducing the number of parts required for assembly, improving overall assembly efficiency, and lowering overall cost. Furthermore, the position of the drive mechanism assembly 5 is optimized; it is directly positioned within the length of the air guide plate 2 without being directly connected to it for synchronous rotation, thereby improving product reliability and preventing abnormal airflow or noise at the air outlet.
[0047] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
