Description

Technical Field

[0001] This application relates to the technical field of air conditioning, and more specifically, to an air conditioning wind deflector structure. Background Technology

[0002] The core of windless air conditioning technology lies in the dispersion and softening of airflow. Windless air conditioners, utilizing this technology, have become the preferred choice for modern homes and offices. By dispersing cool air into multiple fine airflows, windless air conditioners avoid the concentrated, strong winds of traditional air conditioners, resulting in more even and gentler airflow, thus reducing irritation to the skin and body.

[0003] In related technical means, a perforated wind deflector is installed at the air conditioner outlet. This perforated wind deflector can agitate the blown-out cold air, achieving airflow diffusion so that the air conditioner can blow out cool air without a draft, according to the user's needs. In the process of developing this invention, the inventors discovered that the prior art has at least the following problems: the overall airflow direction is fixed in the above solutions, limiting the adjustment of wind speed and direction, failing to provide a more suitable draftless solution according to specific needs, and resulting in low comfort levels. Summary of the Invention

[0004] This application provides an air conditioning wind deflector structure that can adjust the wind speed and direction during air delivery to meet different air delivery needs and improve the comfort of air delivery.

[0005] The air conditioner wind deflector structure provided in this application adopts the following technical solution:

[0006] An air conditioning deflector structure, comprising:

[0007] A wind deflector assembly is provided corresponding to an air conditioning vent. The wind deflector assembly includes multiple wind deflector components arranged coaxially, and the multiple wind deflector components are rotatably engaged with each other.

[0008] A drive assembly includes a drive source and a rotating shaft. A plurality of wind deflectors are rotatably mounted on the rotating shaft. The drive source drives each wind deflector to rotate so that the wind deflectors can overlap or separate from each other.

[0009] Optionally, a plurality of the wind deflectors form a first diffusion module and a second diffusion module, wherein the first diffusion module and the second diffusion module are arranged along the air supply direction.

[0010] Optionally, the number of wind deflectors in the second diffusion module is three, which are respectively configured as a first diffusion plate, a second diffusion plate and a third diffusion plate. The first diffusion plate, the second diffusion plate and the third diffusion plate are nested in sequence, and the first diffusion plate, the second diffusion plate and the third diffusion plate can form an arc-shaped diffusion plane. The first diffusion plate, the second diffusion plate and the third diffusion plate are all provided with air outlet holes.

[0011] Optionally, the number of windbreaks in the first diffusion module is one, which is configured as a fourth diffusion plate, and the fourth diffusion plate is arranged in a columnar shape.

[0012] Optionally, the distance between the first diffuser plate and the rotating shaft is R1, the distance between the second diffuser plate and the rotating shaft is R2, the distance between the third diffuser plate and the rotating shaft is R3, and the distance between the fourth diffuser plate and the rotating shaft is R4, then R1 > R2 > R3 > R4;

[0013] The length of the first diffuser plate is L1, the length of the second diffuser plate is L2, the length of the third diffuser plate is L3, and the length of the fourth diffuser plate is L4, then L1 > L2 > L3 > L4.

[0014] Optionally, the air outlet adopts a gradient aperture design to improve airflow uniformity.

[0015] Optionally, the diameter of the air outlet holes at both ends of the wind deflector along the axial direction is larger than the diameter of the air outlet holes at the central region of the wind deflector.

[0016] Optionally, each of the windshield components has an antistatic coating on its surface, which reduces dust adsorption.

[0017] Optionally, it also includes a drive component, which further includes a gear transmission module. The gear transmission module includes multiple gears that correspond one-to-one with the windshield. The drive source drives the gears respectively to drive the synchronous or independent adjustment of the multiple windshields.

[0018] Optionally, it also includes a temperature and humidity sensor, which is electrically connected to the drive source to automatically adjust the rotation angle of the windshield based on temperature and humidity data.

[0019] As can be seen from the above technical solutions, the embodiments of this application have the following advantages:

[0020] In actual use, the air conditioner delivers air to the air outlet. The drive unit rotates the baffles, allowing each baffle to adjust its angle independently. When the airflow passes through these baffles, it encounters resistance, reducing its speed. When the drive unit rotates the baffles so that they at least partially overlap, the effective area of ​​the air outlet is reduced, decreasing the airflow and intensity while increasing the wind speed. Conversely, when the baffles rotate to move away from each other, the effective area of ​​the air outlet increases, increasing the airflow and intensity while decreasing the wind speed. This allows for flexible adjustment of the airflow according to user needs. Stepless adjustment is achieved through the overlapping of the baffles, replacing traditional fixed grilles and enabling multiple airflow modes from light to strong winds. This allows for rapid cooling of the ambient temperature and control of the airflow speed for a windless cooling effect. Secondly, the coordinated rotation of multiple wind deflectors can create complex combinations of airflow directions, enabling flexible control of the airflow direction and achieving directional airflow or windless operation in a specific area. This meets the airflow needs of different locations and provides a more personalized airflow experience. Multiple wind deflectors can also reorganize and redistribute the airflow, making it more evenly distributed in the space, thereby improving the comfort of the airflow. Attached Figure Description

[0034] This application provides an air conditioning wind deflector structure that can adjust the wind speed and direction during air delivery to meet different air delivery needs and improve the comfort of air delivery.

It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in a sequence other than that illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0037] To facilitate understanding, let's first briefly explain the airflow direction adjustment method of traditional air conditioners. Traditional air conditioners typically use a mechanical blade design to adjust the airflow direction by physically adjusting the outlet. While simple, this method has some significant drawbacks in practical use. For example, traditional air conditioners blow air at a relatively high speed, resulting in concentrated and unidirectional cold air that can easily blow directly onto the body, causing a sudden drop in local temperature. Prolonged exposure to this environment can lead to rapid evaporation of moisture from the skin's surface, causing dryness, tightness, and even itching. Furthermore, when cold air is concentrated on a specific part of the body for an extended period, especially the head or neck, it can cause vasoconstriction and impaired blood circulation, leading to discomfort.

[0038] Please see Figure 1 and Figure 2 This is one embodiment of an air conditioning deflector structure in this application. The air conditioning deflector structure includes a deflector assembly 1 and a drive assembly (not shown in the figure). The deflector assembly 1 is correspondingly arranged with the air conditioning outlet. The deflector assembly 1 includes multiple deflector elements arranged coaxially, which are rotatably engaged with each other. The drive assembly can drive the multiple deflector elements to rotate and adjust the angle of each deflector element, thereby controlling the size and direction of the airflow. Specifically, the drive assembly includes a drive source and a rotating shaft. The multiple deflector elements are rotatably arranged on the rotating shaft. The drive source drives each deflector element to rotate, so that the deflector elements can overlap or separate from each other.

[0039] Understandably, in actual use, the air conditioner delivers air to the air outlet. The drive source rotates the baffles, allowing each baffle to adjust its angle independently. When the airflow passes through these baffles, it encounters resistance due to their obstruction, thus reducing its speed. When the drive assembly rotates the baffles so that they at least partially overlap, the effective area of ​​the air outlet is reduced, decreasing the airflow and thus the intensity of the airflow, while the wind speed relatively increases. Conversely, when the baffles rotate and move apart, the effective area of ​​the air outlet is increased, increasing the airflow and thus the intensity of the airflow, while the wind speed decreases. This allows for flexible adjustment of the airflow according to the user's needs. Stepless adjustment is achieved through the overlapping of the baffles, replacing the traditional fixed grille and enabling multiple airflow modes from gentle breeze to strong wind. This allows for rapid cooling of the ambient temperature while controlling the airflow speed for a windless cooling effect. Secondly, the coordinated rotation of multiple wind deflectors can create complex combinations of airflow directions, enabling flexible control of the airflow direction and achieving directional airflow or windless operation in a specific area. This meets the airflow needs of different locations and provides a more personalized airflow experience. Multiple wind deflectors can also reorganize and redistribute the airflow, making it more evenly distributed in the space, thereby improving the comfort of the airflow.

[0040] Multiple wind-blocking components in the wind-blocking assembly 1 form a first diffusion module 2 and a second diffusion module 3, which are arranged along the air supply direction. When the airflow exits from the air outlet, it first passes through the first diffusion module 2 along the air supply direction. The first diffusion module 2 initially disperses the concentrated and high-velocity airflow by changing the cross-sectional area and flow direction of the airflow. The first diffusion module 2 can reduce the airflow velocity and increase the airflow coverage area, creating conditions for subsequent secondary diffusion. In some embodiments, the first diffusion module 2 can take the form of a perforated plate, a grid, or guide vanes, so that the airflow is divided into multiple small airflow streams when passing through.

[0041] Although the airflow after primary diffusion is dispersed, it may still possess a certain speed and concentration. The function of the second diffusion module 3 is to further disperse this airflow, making it more evenly distributed throughout the space. The second diffusion module 3 can further reduce the airflow speed, and through complex flow channel design or more dispersion units, make the airflow gentler, avoiding direct blowing onto the human body. In some embodiments, the diffusion module can adopt a honeycomb structure, multi-layer windbreaks, or a soft-wind microporous matrix to further disperse the airflow. Through two-stage diffusion, the airflow distribution in the space is more uniform, avoiding situations where the local wind speed is too high or too low. At the same time, the airflow speed is significantly reduced, the wind feel is gentler, and the discomfort caused by direct blowing onto the human body is reduced. By adjusting the design parameters of the first diffusion module 2 and the second diffusion module 3, such as the spacing between the first diffusion module 2 and the second diffusion module 3, the aperture of the air outlet 11 in the windbreak, and the angle of each windbreak, different air supply needs can be flexibly adapted.

[0042] Please see Figures 1 to 5 The first diffusion module 2 consists of at least one windbreak component, and the second diffusion module 3 consists of multiple nested windbreak components. In this embodiment, the first diffusion module 2 consists of one windbreak component, and the second diffusion module 3 consists of three windbreak components, which will be described in detail using this as an example. The three windbreak components in the second diffusion module 3 are respectively configured as a first diffusion plate 31, a second diffusion plate 32, and a third diffusion plate 33. The first diffusion plate 31, the second diffusion plate 32, and the third diffusion plate 33 are nested sequentially, and the first diffusion plate 31, the second diffusion plate 32, and the third diffusion plate 33 can form an arc-shaped diffusion surface. The first diffusion plate 31, the second diffusion plate 32, and the third diffusion plate 33 are all provided with air outlet holes 11. The airflow is dispersed into multiple tiny airflows by the multiple air outlet holes 11. These tiny airflows have different directions and speeds, which makes the originally concentrated airflow dispersed, so as to achieve a windless air delivery effect and avoid the concentrated strong wind when the traditional air conditioner blows directly. In other embodiments, the size and type of the air outlet 11 of the first diffuser plate 31, the air outlet 11 of the second diffuser plate 32, and the air outlet 11 of the third diffuser plate 33 can be the same or different.

[0043] One of the windbreak components in the first diffusion module 2 is configured as a fourth diffusion plate 21, which is columnar in shape. It can be understood that the columnar shape of the fourth diffusion plate 21 can change and guide the direction of the airflow, allowing the concentrated and high-velocity airflow to be initially dispersed before entering the second diffusion module 3, transforming a unidirectional airflow into a multidirectional airflow and increasing the coverage area of ​​the airflow; simultaneously, the columnar shape of the fourth diffusion plate 21 can block the airflow, thereby reducing its speed.

[0044] The first diffuser plate 31, the second diffuser plate 32, and the third diffuser plate 33 enclose an arc-shaped diffusion plane. The airflow, initially diffused by the fourth diffuser plate 21, enters the diffusion plane and is further dispersed by the first, second, and third diffuser plates 31, 32, and 33, resulting in a wider coverage area and a gentler airflow. When the driving assembly drives the first, second, and third diffuser plates 31 and 33 to overlap, the initially diffused airflow enters the first diffuser plate 31 for further dispersion. After passing through the first diffuser plate 31, the airflow continues into the second diffuser plate 32, where the air outlet 11 further disperses the airflow, further reducing its speed and making it more uniform. Finally, the airflow enters the third diffuser plate 33, where the air outlet 11 performs a final dispersion, making the airflow even gentler and ultimately achieving a windless or breeze-like air delivery effect.

[0045] In this embodiment, the first diffuser plate 31, the second diffuser plate 32, and the third diffuser plate 33 have the same structure, and the first diffuser plate 31 will be used as an example for explanation. The first diffuser plate 31 has an air outlet surface 12, two windproof surfaces 13 disposed on both sides of the air outlet surface 12, and a plurality of air outlet holes 11 disposed on the air outlet surface 12. The cross-section of the air outlet surface 12 is a quarter-circle arc. Since the first diffuser plate 31, the second diffuser plate 32, and the third diffuser plate 33 are coaxial and nested, the direction and diffusion range of the airflow can be further optimized by adjusting the angles of the first diffuser plate 31, the second diffuser plate 32, and the third diffuser plate 33 to adapt to different usage scenarios.

[0046] Furthermore, the distance between the first diffuser plate 31 and the rotating shaft is R1, the distance between the second diffuser plate 32 and the rotating shaft is R2, the distance between the third diffuser plate 33 and the rotating shaft is R3, and the distance between the fourth diffuser plate 21 and the rotating shaft is R4, so R1 > R2 > R3 > R4. The length of the first diffuser plate 31 is L1, the length of the second diffuser plate 32 is L2, the length of the third diffuser plate 33 is L3, and the length of the fourth diffuser plate 21 is L4, so L1 > L2 > L3 > L4. Along the air supply direction, the distances between the fourth diffuser plate 21, the third diffuser plate 33, the second diffuser plate 32, and the first diffuser plate 31 and the rotating shaft gradually increase, which can ensure that the coverage area of ​​the airflow gradually expands when passing through each diffuser plate; the lengths of the fourth diffuser plate 21, the third diffuser plate 33, the second diffuser plate 32, and the first diffuser plate 31 decrease step by step, which facilitates the nesting of multiple wind deflectors to save space and reduce the overall volume of the wind deflector assembly 1.

[0047] The air outlet 11 employs a gradually changing aperture design to improve airflow uniformity. Understandably, airflow passing through a gradually changing aperture reduces turbulence and eddies. By rationally designing the aperture size based on the airflow characteristics and optimizing the airflow velocity at each air outlet 11, airflow can pass through the outlet 11 more smoothly, avoiding drastic airflow fluctuations, thereby improving airflow uniformity, significantly reducing situations of excessively high or low local wind speeds, improving airflow comfort, and thus reducing or eliminating the feeling of wind. The diameter, distribution density, and shape (circular, hexagonal, square, etc.) of the air outlet 11 can be optimized based on fluid dynamics simulations (such as CFD analysis) to balance wind resistance and the effect of no wind.

[0048] Please see Figure 6 In this embodiment, the diameter of the air outlets 11 at both ends of the wind deflector along the axial direction is larger than the diameter of the air outlets 11 in the central area of ​​the wind deflector. In one possible implementation of the above embodiment, the number of large-diameter air outlets 11 increases towards both ends of the wind deflector, until all air outlets 11 at both ends are large-diameter air outlets 11. It is understood that the diameter of the air outlets 11 in the middle is smaller, while the diameter of the air outlets 11 at both ends is larger. This design results in lower porosity in the middle and higher porosity at both ends. When airflow passes through the wind deflector, the lower porosity in the middle causes greater resistance and reduced speed, effectively dispersing the airflow and preventing excessive concentration of airflow in the middle area. The higher porosity at both ends results in less resistance and relatively higher speed, guiding the airflow to diffuse from the middle to both ends, further optimizing the airflow distribution. Simultaneously, the larger diameter air outlets 11 guide the airflow smoothly, reducing airflow fluctuations and ultimately achieving a more uniform airflow distribution.

[0049] In another possible implementation of the above embodiment, the diameter of the air outlet 11 gradually increases from the center of the wind deflector towards both ends. Through this gradient change in diameter, the airflow gradually disperses from the center to both ends as it passes through the wind deflector, ultimately achieving a more uniform airflow distribution. By adjusting the size distribution of the apertures, the uniformity, smoothness, and coverage of the airflow can be significantly improved. Furthermore, by rationally designing the distribution of aperture and porosity, the airflow distribution can be further optimized, improving the comfort and energy efficiency of the air supply.

[0050] Static electricity is one of the main causes of dust adsorption. When the static electricity on the surface of the windshield is reduced, the dust adsorption capacity is significantly reduced. Each windshield surface is coated with an antistatic coating, which reduces dust adsorption. The antistatic coating usually has a certain degree of conductivity, which can quickly conduct static electricity away, preventing static electricity from accumulating on the surface, keeping the windshield surface clean, reducing the frequency of cleaning and maintenance, and lowering equipment maintenance costs. At the same time, a clean surface of the windshield can reduce airflow resistance, optimize airflow distribution, and improve air delivery efficiency.

[0051] In this embodiment, the windshield can be made of ABS plastic. ABS plastic is easy to process and has low cost, but it may deform after long-term use. To further enhance the bending strength of the windshield, the windshield can be made of high-performance engineering plastic with glass fiber reinforced PA66, which has a bending strength ≥150MPa, excellent mechanical properties and heat resistance, and is suitable for high wind speed environments.

[0052] The drive assembly also includes a gear transmission module, which comprises multiple gears corresponding one-to-one with the windshield components. The drive source drives each gear to synchronously or independently adjust the multiple windshield components. In this embodiment, the drive source is the power source for the entire system. The drive source is preferably a micro stepper motor. The gear transmission module uses micro planetary gears or harmonic gears to improve transmission accuracy. A gear module of 0.3-0.5mm is recommended to match the torque requirements of the plastic baffle. It can be understood that the angle adjustment of the windshield is achieved by the motor driving the gear transmission module. Specifically, the motor is connected to the main gear, and the motor's output shaft is connected to a main gear via a coupling or directly. The rotation of the main gear drives the first-stage driven gear, which in turn drives the second-stage driven gear, and so on. By rationally designing the gear ratio, different transmission ratios can be achieved, thereby precisely controlling the rotation angle of the windshield.

[0053] Furthermore, a gap of 0.1-0.2mm is reserved at the gear meshing point to avoid jamming caused by thermal expansion or deformation, thereby enabling angle adjustment of each windshield component.

[0054] To achieve intelligent control of the air conditioning baffle structure, a temperature and humidity sensor is also included. This sensor is electrically connected to a drive source to automatically adjust the rotation angle of the baffle based on temperature and humidity data. The relevant control technology is existing and will not be elaborated upon here.

[0055] Based on the different cooling times and cooling needs, the air conditioner baffle structure can be set to at least four states, each state corresponding to a different mode. The following describes each mode in turn.

[0056] State 1: Rapid cooling mode, suitable for the initial stage of cooling. (Example: ...) Figure 7 As shown.

[0057] Since rapid cooling is required in the initial stage of cooling, the air conditioner outlet needs to ensure that there are no obstructions in the main airflow path. This is to reduce resistance, increase airflow and cooling capacity, and achieve rapid cooling.

[0058] In state one, the first diffusion module 2 and the second diffusion module 3 need to avoid the main airflow path. Specifically, the fourth diffuser plate 21 in the first diffusion module 2 rotates 90° clockwise or counterclockwise, positioning it vertically above or below the air conditioner outlet, thus avoiding obstruction. In the second diffusion module 3, the first diffuser plate 31 and the third diffuser plate 33 are symmetrically arranged along the airflow path, positioned above and below the air conditioner outlet, respectively. The second diffuser plate 32 rotates 90° clockwise or counterclockwise, positioning it vertically and overlapping with either the first or third diffuser plate 31, thus avoiding obstruction. This avoidance between the second diffuser plate 32 and the fourth diffuser plate 21 minimizes wind resistance along the main airflow path, thereby maximizing airflow.

[0059] Furthermore, due to the increased wind speed, it is advisable to add porous sound-absorbing material to the air conditioner vents to suppress high-frequency noise. Polyurethane foam can be selected as a porous sound-absorbing material.

[0060] State 2: Windless Comfort Mode, suitable for the later stages of cooling. For example... Figure 8 As shown.

[0061] Since rapid cooling is no longer needed in the later stages of cooling, it is necessary to evenly diffuse the airflow and reduce the wind speed to below 0.3m / s. Therefore, the airflow from the air conditioner outlet needs to be processed by the air conditioner baffle structure to make the air delivered by the air conditioner more uniform and gentle, thereby reducing irritation to the skin and body.

[0062] In state two, primary diffusion is achieved using the first diffusion module 2, followed by secondary diffusion using the second diffusion module 3. Specifically, the fourth diffusion plate 21 in the first diffusion module 2 is located on the main airflow path, while the first diffusion plate 31, second diffusion plate 32, and third diffusion plate 33 in the second diffusion module 3 enclose an arc-shaped diffusion plane, all located along the airflow path. The fourth diffusion plate 21 alters and guides the airflow direction, initially dispersing the concentrated and high-velocity airflow before it enters the second diffusion module 3, transforming a unidirectional airflow into a multidirectional one, thus increasing the airflow coverage. Simultaneously, the fourth diffusion plate 21 obstructs the airflow, reducing its speed. The airflow, after initial diffusion, enters the diffusion plane, where the first diffusion plate 31, second diffusion plate 32, and third diffusion plate 33 further disperse the multidirectional airflow, making it gentler and ultimately achieving a windless airflow effect.

[0063] State 3: Directional air supply mode. This application embodiment uses the example of directional air supply to a downward-sloping area for illustration. Figure 9 As shown.

[0064] When directional air supply is used, precise control of airflow direction and volume distribution is required to ensure that the airflow reaches the designated area as needed. In state three, to achieve directional air supply to the area diagonally downwards, the first diffusion module 2 needs to avoid the main path of the airflow, thereby increasing the resistance in the upper area. The second diffusion module 3 needs to guide the airflow, that is, the fourth diffusion plate 21 in the first diffusion module 2 rotates 90° counterclockwise, so that the fourth diffusion plate 21 is set vertically and located in the area above the air conditioner outlet, thereby achieving the avoidance of the airflow. In the second diffusion module 3, the first diffusion plate 31 is located in the area above the air conditioner outlet, the second diffusion plate 32 is located in the front area of ​​the air conditioner outlet, and the third diffusion plate 33 is rotated 90° counterclockwise so that the third diffusion plate 33 overlaps with the second diffusion plate 32. The air outlet 11 of the third diffusion plate 33 is offset from the air outlet 11 of the second diffusion plate 32, which changes the effective porosity and increases the resistance in the front area, while avoiding the area below. The airflow passes through the overlapping second diffusion plate 32 and third diffusion plate 33 to reduce the wind speed and guide the airflow, so that the airflow turns downward after reaching this point and then flows towards the area below, thereby achieving the effect of directional air delivery.

[0065] Status 4: Intelligent Hybrid Mode.

[0066] The intelligent hybrid mode aims to dynamically switch states based on real-time environmental data. In this embodiment, an infrared human body sensor is integrated to detect the user's location, and combined with a temperature and humidity sensor to obtain temperature and humidity data, thereby automatically adjusting the rotation angle of the windshield and automatically selecting the air delivery strategy.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
