[0043] It should be further understood that the term "and / or" used in the present description and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0044] See also Figure 1-5 An embodiment of the present invention provides an air outlet structure 1 for an air conditioner, including an air guide plate 11. The air guide plate 11 is provided with a plurality of through air guide holes 12 at intervals. Each air guide hole 12 is provided with an air guide portion 13 extending to both sides. The air guide portion 13 is provided with an air guide channel 131 connected to the air guide hole 12.

[0045] In this embodiment, a plurality of through air guide holes 12 are arranged along the length direction or the width direction of the air guide plate 11, and the air guide portion 13 is extended on the side of the air guide hole 12. An air guide portion 13 is provided on both sides of each air guide hole 12, wherein the air guide portions 13 on both sides are respectively located on the inner and outer sides of the air guide plate 11, and the air guide portion 13 has an air guide channel 131 connected to the air guide hole 12. When the air conditioner discharges air, it first enters the inner air guide channel 131, then passes through the air guide hole 12, and finally discharges air from the outer air guide channel 131. This arrangement can better guide the direction of the air outlet and make the air outlet more uniform. In specific implementation, the air guide plate 11 can use engineering plastics with good strength and plasticity (such as ABS plastic) as the manufacturing material of the air guide plate 11. This material can ensure that the air guide plate 11 is not easily deformed during long-term use. The thickness of the air guide plate can be set to 2.5-3.5mm, the diameter of the air guide hole 12 can be set to 5-10mm, and the shape of the air guide channel 131 can be set to a gradually expanding shape to optimize the air flow performance and ensure that the surface roughness of the air guide channel 131 reaches a preset value (such as Ra1.6-Ra3.2μm) to reduce air flow resistance.

[0046] The wind guide plate 11 of this embodiment is based on the traditional wind guide plate, and wind guide parts 13 are added from both sides of the wind guide hole 12, so that the air outlet channel (i.e., the air guide channels on both sides + the air guide holes) is extended to achieve uniform air outlet, and when the air flows through, the wind can be transported to a farther distance, thereby realizing long-distance air supply.

[0047] Specifically, such as Figure 4 As shown, the cross-sectional diameter of the air guiding channel 131 gradually increases in a direction away from the air guiding hole 12 .

[0048] In this embodiment, one end of the air guide portion 13 is connected to the air guide hole 12, and the other end of the air guide portion 13 is gradually enlarged to achieve a gradual increase in the cross-sectional diameter of the air guide channel 131 in the direction away from the air guide hole 12. The benefits of this arrangement are as follows: a. Optimizing air flow rate and pressure distribution: During air discharge, after air enters the air guide channel 131 from the air guide hole 12 through the inner air guide channel 131, the cross-sectional diameter of the air guide channel 131 gradually increases. According to the continuity equation of fluid mechanics (i.e., flow rate is inversely proportional to cross-sectional area), the air flow rate will gradually decrease. This can avoid the local strong wind sensation caused by excessive wind speed at the air outlet, making the blown air more uniform and gentle, and improving user comfort. At the same time, the pressure will gradually increase, which helps to more stably transport the air to a longer distance, enhance the air supply effect, and enable more effective circulation and mixing of indoor air. b. Reduce noise generation: High-speed airflow is prone to noise when it suddenly encounters narrow or irregular channels. By setting up this gradual channel structure, the air can transition more smoothly, thereby reducing the noise generated by air flow and creating a quieter indoor environment. c. Improve air flow efficiency: Better guide the flow of air, allowing it to diffuse in the direction of the designed channel, reducing air backflow and energy loss, and improving the air flow efficiency of the entire air conditioning outlet structure.

[0049] In a specific implementation, the air guide channel 131 can be configured in the shape of a trapezoidal prism, with the air guide portion 13 being a trapezoidal prism, and the air guide channel 131 being disposed within the trapezoidal prism. The air guide channel 131 extends outward from the end connected to the air guide hole 12, with its cross-sectional width and height gradually increasing, thereby increasing the cross-sectional area (cross-sectional diameter) of the air guide channel 131. The air guide channel 131 can also be configured in a hyperbolic shape, with the air guide portion shaped like a portion of a hyperbola, and the air guide channel 131 gradually increasing in cross-sectional diameter along the curved trajectory of the hyperbola. This shape can provide a smoother airflow transition and more precisely control the airflow diffusion angle and velocity distribution. The air guide channel 131 can also be set to a combination of a cone and an arc: the air guide portion 13 is set to a cone at one end close to the air guide hole 12, and the end where the cone is connected to the air guide hole 12 is not capped, and its cross-sectional diameter can be less than or equal to the cross-sectional diameter of the air guide hole 12, and then gradually transitions from the other end of the cone to form an arc that diffuses toward both sides. This combination shape combines the initial acceleration of the cone and the smooth expansion effect of the arc to achieve better air guiding performance.

[0050] Specifically, such as Figure 4As shown, the air guide portion 13 can also be set as a trumpet hole. The aperture of the trumpet hole close to the air guide hole 12 is the same as the aperture of the air guide hole 12. The aperture of the other end of the trumpet hole (i.e., the end away from the air guide hole 12) is designed according to the required air outlet range and diffusion angle. In order to achieve long-distance air supply, the aperture of the other end of the trumpet hole can be set to 5-10mm in this embodiment. The expansion angle of the trumpet hole can be set between 30° and 60°, so that the air flows out of the trumpet hole more evenly and smoothly. In specific implementation, the expansion shape of the trumpet hole can be set to a straight line that spreads outward, or it can be set to an outward arc shape (see Figure 4 shape).

[0051] The length, diameter and curvature of the horn holes on both sides extending out of the air guide plate 11 can be adjusted. The horn holes can also be designed into a grid or hexagon, and the number and density of the air guide holes 12 can be increased to make the airflow more delicate and uniform.

[0052] In order to make the air outlet smoother, a guide structure (such as a guide plate or guide ribs) can be set in the air guide channel 131 to guide the air flow. These guide structures can divide the air into multiple uniform sub-flows to avoid local airflow accumulation or flow dead zones in the air guide channel 131. The shape and arrangement of the guide plates should be optimized according to the shape of the channel and the airflow characteristics. For example, a streamlined guide plate can be used, and its direction and angle can be adjusted according to the actual effect to minimize the resistance to the airflow and maximize the uniform flow.

[0053] The air duct can also be treated with antistatic treatment to prevent static electricity from attracting dust and impurities. When dust accumulates on the inner surface of the air duct 131, it can disrupt airflow uniformity and increase local airflow resistance. Antistatic treatment can be achieved by adding an antistatic agent, using an antistatic coating, or using materials with antistatic properties to ensure that the inner surface of the duct remains clean over the long term and maintain good airflow uniformity.

[0054] Small airflow control devices, such as miniature fans or airflow control valves, can also be installed within the airflow channel 131 or near the air outlet. These devices can be dynamically adjusted based on real-time airflow monitoring results (using airflow sensors) to compensate for airflow unevenness caused by changes in the external environment or the internal structure of the air conditioner. For example, if weak airflow is detected in a certain area, the airflow in that area can be enhanced by adjusting the speed of the miniature fan or the opening of the valve in the corresponding location to achieve dynamic balance.

[0055] Specifically, refer to Figure 4The cross-sectional diameter d of the air guide hole 12 ranges from 3 to 5 mm. In this diameter range, the air guide hole 12 is relatively small, and the total air volume can be evenly distributed to the plurality of air guide holes 12, avoiding the situation that air is concentrated in some areas and rare in other areas due to the excessively large hole. The plurality of air guide holes 12 work together to make the airflow more evenly distributed in the air outlet area, which helps to achieve uniform air outlet effect and improve the overall air conditioning effect in the room. Moreover, under a certain air volume, a smaller hole diameter can generate a relatively high air outlet pressure, so that the air can be blown to a farther distance, thereby expanding the effective coverage range of the air conditioner, while avoiding the noise and discomfort caused by the excessively fast air outlet speed.

[0056] Specifically, the spacing between adjacent air guide holes 12 is 10 to 15 mm.

[0057] In this embodiment, appropriate spacing is needed to achieve uniform air distribution. If the spacing is too small, the airflows blown by adjacent air guide holes 121 may interfere with each other, causing turbulence or airflow superposition, thereby affecting the uniformity of air outlet. If the spacing is too large, some areas may not be effectively covered by the airflow. Within the spacing range of 10 to 15 mm, the airflow blown by each air guide hole 12 has enough space to diffuse, avoiding mutual interference of adjacent airflows, so that the air blown by the air conditioner can be evenly distributed in each area of the air outlet, thereby more evenly adjusting the temperature and humidity in the room and providing a comfortable use environment for the user. Moreover, this spacing range helps to enhance the structural strength of the air guide plate 11 while ensuring the air outlet effect, avoids excessive density of the air guide holes 12, and prevents the air guide plate 11 from deforming due to insufficient local strength during use, thereby ensuring the service life and reliability of the air guide plate 11.

[0058] As shown in Figure 6 The air conditioner 2 provided by the embodiment of the present application further comprises the air outlet structure 1 of the air conditioner as described above.

[0059] In this embodiment, the air-conditioning outlet structure 1 is installed to the corresponding position of the air-conditioner outlet. Specifically, it can be fixed by snap-fit ​​connection or screws to ensure that the air guide plate 11 is firmly installed. After the assembly is completed, the air-conditioning outlet structure 1 can be fully inspected in advance. First, use an anemometer to detect the wind speed distribution through the air guide holes 12 and the air guide channel 131 to ensure that the wind speed is uniform. At the same time, check whether the air guide plate 11 has surface defects, deformation and other problems. In addition, the reliability and durability of the air guide plate 11 are tested by simulating the air-conditioning operating environment, such as conducting long-term operation tests under different temperature, humidity and wind speed conditions to observe whether the air guide plate 11 can work normally, and whether the air guide holes 12 and the air guide channel 131 are blocked or damaged. According to the test results, the air-conditioning outlet structure 1 is adjusted and optimized as necessary to ensure that its performance reaches the best state. Among them, the air conditioner 2 is a vertical air conditioner, and the air outlet structure of the air conditioner is also a vertical air outlet structure. In different operating modes, the air guide plate 11 can be controlled to supply air to the left and right. In addition, by extending the air guide part 13 on the air guide plate 11, the wind speed can be increased and the air outlet temperature at the air outlet panel can be reduced.

[0060] In the prior art, the traditional air guide plate is set to a structure with inward holes to disperse the outgoing air, so as to achieve the effect that the user does not feel the cold air blowing directly. However, this structure cannot effectively control the air supply range, which is not conducive to the user's temperature control in the use environment. In addition, the traditional air guide plate can only adjust the left and right wind directions and the wind speed is fixed during normal operation. At low wind speeds, the indoor temperature changes unevenly, and the indoor environment cannot be effectively controlled, resulting in a poor user experience. Therefore, an embodiment of the present invention also provides a control method for an air conditioner, such as Figure 7 As shown, including S10-S20:

[0061] S10, obtaining an operating mode of the air conditioner, and controlling the air conditioner to operate according to the operating mode;

[0062] S20 , controlling the air guide plate 11 to rotate within a corresponding rotation angle range according to the air outlet gear in the operating mode.

[0063] In this step, after the air conditioner is turned on, the position of the air guide plate 11 is first checked, and the air guide part 13 is restored to a closed state to prevent malfunctions during subsequent operation and abnormal position of the air guide plate 11, which reduces the user experience.

[0064] In different operating modes, the air conditioner achieves more uniform temperature distribution by controlling the rotation angle of air guide plate 11, based on the principle that hot air rises and cold air sinks. In cooling mode, cold air is directed to appropriate locations, creating a good temperature gradient indoors and preventing local overcooling. In heating mode, hot air is directed to different locations indoors, accelerating heat transfer and achieving a more uniform temperature throughout the room, thereby improving the air conditioner's efficiency.

[0065] This embodiment controls the rotation of the air guide plate 11 according to the operating mode and the air outlet gear, so that the energy of the air conditioner can be used more efficiently, so as to accurately deliver air to the target area under different operating modes and avoid unnecessary energy waste.

[0066] In one embodiment, if Figure 8 As shown, S20 includes:

[0067] S21. If the operating mode of the air conditioner is cooling mode, confirm the air outlet position of the air conditioner;

[0068] S22: If the air outlet gear is the first wind gear, controlling the air guide plate 11 to rotate within a preset first angle range;

[0069] S23. If the air outlet gear is the second wind gear, controlling the air guide plate 11 to rotate within a preset second angle range, wherein the intensity of the second wind gear is greater than that of the first wind gear, and the second angle range is greater than the first angle range;

[0070] S24. If the air outlet gear is the silent gear, control the air guide plate 11 to rotate within a preset third angle range, wherein the third angle range is smaller than or equal to the first angle range.

[0071] In S21, in the control system of the air conditioner, the current operating mode of the air conditioner is obtained through the user's operation settings on the remote control or control panel. When the user presses the cooling mode button, the control system of the air conditioner will receive the corresponding signal and mark the operating mode as cooling mode. At the same time, the current air outlet gear will be checked to confirm the air outlet gear required by the user.

[0072] In S22, the first wind speed gear is a relatively low wind speed gear, which is suitable for a scene where the user has no high requirement for the cooling intensity or wants to blow air gently. When the air conditioner detects that the air outlet gear is the first wind gear, the air conditioner controls the air deflector 11 to rotate in a preset first angle range. The first angle range can be set to a small angle, for example, ±15° to ±30° (± respectively represents the left and right air outlet directions, for example, the first angle range is ±15°, that is, the air deflector 11 can rotate back and forth between the left side 15° and the right side 15°, or the first angle range is ±30°, that is, the air deflector 11 can rotate back and forth between the left side 30° and the right side 30°). In this angle range, the air flow rate can be increased, so that the air deflector 11 blows in a smaller range, and the indoor cooling is more rapid and uniform. In the specific implementation process, the first wind gear can be called a low wind gear or a medium wind gear. In the low wind gear or the medium wind gear, the fan speed can also be controlled to increase by a predetermined speed (such as 100 revolutions), and then the air deflector 11 is controlled to rotate in a preset first angle range.

[0073] In S23, when the user switches the air outlet gear to the second wind gear, the intensity of this gear is greater than that of the first wind gear, indicating that the user needs stronger cooling effect. The air conditioner controls the air deflector 11 to rotate in a preset second angle range. Since the intensity of the second wind gear is greater, the corresponding second angle range also needs to be greater than the first angle range. For example, the second angle range can be set to ±30° to ±90°. The two side horn openings of the air deflection part 13 can blow the cold air away to achieve the purpose of not blowing the wind, so that the user experience is improved, and more cold air can be blown out in a larger range, so that the air conditioner can more evenly distribute the cold air in a larger area, improve the cooling efficiency, and meet the user's needs in a larger space or when rapid cooling is needed. In the specific implementation process, the second wind gear can be called a high wind gear or a strong gear. When the high wind gear or the strong gear is used, the air deflector 11 rotates at a large angle and does not block the blowing of a larger air volume. The horn openings arranged on both sides of the air deflector can disperse the airflow. In this way, the injection noise generated when the air flows at high speed through the horn openings of the air deflection part 13 can be reduced, and the air conditioner blows the air more evenly.

[0074] In S24, when the user selects the silent gear, this gear mainly considers reducing the noise during the operation of the air conditioner while maintaining a certain cooling effect. When the rotation angle of the air guide plate 11 is large, there will be noise when the air guide plate 11 rotates. Therefore, it is necessary to set the third angle range to be smaller, that is, less than or equal to the first angle range, for example, set to ±15~30°. Within this smaller angle range, the air guide plate 11 can guide the airflow to a relatively small area, and due to the reduction in the air outlet range, the air conditioner can appropriately reduce the speed of the fan, reduce the turbulence and impact of the airflow, thereby achieving the purpose of reducing noise. During specific implementation, if the user adjusts to the silent mode, it is also necessary to reduce the fan speed, and then rotate it within the predetermined third angle range, and increase the rotation speed of the air guide plate 11 to make the air flow blow out quickly, reducing the impact on the air volume in this operating mode. The air guide plate 11 of this embodiment will not suppress the air volume when rotated at a small angle, and can avoid the buzzing sound caused by vortexes in the internal air duct due to the air guide plate 11 opening and closing too small an angle, thereby doubly suppressing the noise at the noise generation point (high-speed operation of the fan) and the propagation process (air guide plate isolation).

[0075] In one embodiment, if Figure 9 As shown, S20 includes:

[0076] S25. If the operating mode of the air conditioner is the heating mode, confirm the air outlet position of the air conditioner;

[0077] S26, if the air outlet gear is the first wind gear, controlling the air guide plate 11 to rotate within a preset fourth angle range;

[0078] S27. If the air outlet gear is the second wind gear, controlling the air guide plate 11 to rotate within a preset fifth angle range, wherein the intensity of the second wind gear is greater than the intensity of the first wind gear, and the fifth angle range is greater than the fourth angle range;

[0079] S28. If the air outlet gear is the silent gear, control the air guide plate 11 to rotate within a preset sixth angle range, wherein the sixth angle range is smaller than or equal to the fourth angle range.

[0080] In this embodiment, in S25, similar to the aforementioned S21, the current operating mode of the air conditioner is obtained through the user's operation settings on the remote control or control panel. When the user presses the heating mode button, the control system of the air conditioner will receive the corresponding signal and mark the operating mode as heating mode. At the same time, the current air outlet gear will be checked to confirm the air outlet gear required by the user.

[0081] In the heating mode, the user pursues rapid temperature rise, so the temperature drop of the air guide part 13 on the air deflector 11 is reduced as much as possible during control. Specifically, when the air conditioner detects that the air outlet position is the first air outlet position, the air conditioner controls the air deflector 11 to rotate at a preset fourth angle range. The fourth angle range is set to be small, but due to the principle of hot air rising and cold air sinking, the fourth angle range needs to be larger than the first angle range, which can be set to ±45-90°. At this angle, the air volume flowing through the air guide hole 12 is small, and the working efficiency is low. At this time, the horn mouth of the air guide part 13 is mainly relied on as a column to disperse the blown air, so as to achieve the effect of wind not blowing people, and make the temperature change in the room more gentle. Among them, the first air outlet position can be called low air outlet position or medium air outlet position in the specific implementation process.

[0082] When switching to the second air outlet position, the movement angle of the air deflector 11 is larger, that is, the fifth angle range is larger than the fourth angle range, which can be set to ±30-90°. In this way, the working efficiency of the air guide hole 12 is further reduced, so as to maximize the temperature of the air blown out by the air conditioner, and rely on the horn mouth of the air guide part 13 to disperse the airflow, so that the temperature change in the room is more uniform. Among them, the second air outlet position can be called high air outlet position or strong position in the specific implementation process.

[0083] Similarly, when switching to the silent position in the heating mode, the rotation angle of the air deflector 11 is slightly reduced, which can be set to ±45-80°, and the fan speed is controlled to be reduced, so as to realize the silent effect.

[0084] Through the air outlet structure and control method of the air conditioner in the above embodiment, the effect of improving the air flow rate can be effectively achieved. Compared with the traditional air deflector, the overall indoor temperature can be adjusted more quickly, and the problem that the indoor environment temperature is not balanced due to the short air supply distance of the cold air in the low air outlet position is solved. The fan speed can be increased by 100 revolutions in the low position, so as to increase the air supply amount and air flow rate. Referring to the simulation diagrams of Figure 10 and Figure 11 , Figure 10 (a) and Figure 11 (a) is the air outlet channel of the embodiment, Figure 10 (b) and Figure 11 (b) is the air outlet channel of the traditional air deflector, which achieves the effect of the air outlet position of the traditional air deflector. In the high air outlet position, the air deflector form can be further used to arrange the airflow, which has a positive effect on the air speed, air volume and airflow form, and does not need to add an additional motor or other driving mechanism. In the breeze and non-breeze mode, the new form air deflector can be more efficiently used, the cost is reduced, and the effect is increased. The comfort of the air conditioner is improved, and the power consumption of the air conditioner is further reduced.

[0085] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto.
