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

[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, wherein 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, and the air guide portion 13 is provided with an air guide channel 131 communicating with 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 respectively 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. Such a setting can better guide the air outlet direction and make the air outlet more uniform. In the specific implementation, the air guide plate 11 can select 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 air guide plate 11 of this embodiment is based on the traditional air guide plate, and an air guide part 13 is added from both sides of the air guide hole 12, so that the air outlet channel (i.e. the air guide channel on both sides + the air guide hole) 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, 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 the cross-sectional diameter of the air guide channel 131 gradually increasing 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: When the air is discharged, after the air enters the air guide channel 131 from the inner air guide channel 131 from the air guide hole 12, the cross-sectional diameter of the air guide channel 131 gradually increases. According to the continuity equation of fluid mechanics (i.e., the flow rate is inversely proportional to the cross-sectional area), the air flow rate will gradually decrease, which can avoid the feeling of local strong wind caused by excessive wind speed at the air outlet, making the blown wind more uniform and soft, and improving the comfort of the user. At the same time, the pressure will gradually increase, which helps to more stably transport the wind to a farther distance, enhance the air supply effect, and enable the indoor air to circulate and mix more effectively. b. Reduce noise generation: High-speed air flows easily generate 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 so that the air diffuses 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 set to the shape of a trapezoidal prism, the air guide portion 13 is a trapezoidal prism, the air guide channel 131 is set in the trapezoidal prism, the air guide channel 131 extends outward from the end connected to the air guide hole 12, and the width and height of its cross section gradually increase, thereby increasing the cross-sectional area (cross-sectional diameter) of the air guide channel 131. The air guide channel 131 can also be set to a hyperbolic shape, the shape of the air guide portion is similar to a part of the hyperbola, and the air guide channel 131 gradually increases the cross-sectional diameter along the curved trajectory of the hyperbola. This shape can provide a smoother airflow transition and can more accurately control the diffusion angle and velocity distribution of the airflow. 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 to both sides. This combination shape combines the initial acceleration of the cone and the smooth flow expansion effect of the arc to achieve better air guiding performance.

[0050] Specifically, Figure 4As shown, the air guide portion 13 can also be set as a trumpet hole. The aperture of the trumpet hole near 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 (refer to 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 a guide rib) 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 uniform flow.

[0053] The air guide channel can also be treated with antistatic to prevent static electricity from adsorbing dust and impurities. When dust accumulates on the inner surface of the air guide channel 131, it will destroy the uniformity of the airflow and increase the local airflow resistance. Antistatic treatment can be achieved by adding antistatic agents, using antistatic coatings, or using materials with antistatic properties to ensure that the inner surface of the channel remains clean for a long time and maintains good air outlet uniformity.

[0054] A small airflow regulating device, such as a micro fan or an airflow regulating valve, can also be arranged in the air guide channel 131 or near the air outlet. These devices can be dynamically adjusted according to the real-time airflow monitoring results (using airflow sensors) to compensate for the airflow unevenness caused by the external environment or the changes in the internal structure of the air conditioner. For example, when it is detected that the airflow in a certain area is weak, the airflow in the area can be enhanced by adjusting the speed of the micro fan or the valve opening at the corresponding position to achieve dynamic balance.

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

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

[0057] In this embodiment, it is necessary to set a suitable spacing to achieve uniform distribution of air. If the spacing is too small, the airflows blown out of adjacent air guide holes 121 may interfere with each other, causing turbulence or airflow superposition, thereby affecting the uniformity of the air. If the spacing is too large, some areas may not be effectively covered by airflow. Within the spacing range of 10 to 15 mm, it can ensure that the airflow blown out of each air guide hole 12 has enough space to diffuse, avoiding mutual interference between adjacent airflows, so that the air blown out by the air conditioner can be evenly distributed in various areas of the air outlet, thereby more evenly adjusting the indoor temperature and humidity, and providing users with a comfortable use environment. In addition, while ensuring the air outlet effect, this spacing range also helps to enhance the structural strength of the air guide plate 11, avoid the air guide holes 12 being too dense, and prevent the air guide plate 11 from being deformed due to insufficient local strength during use, thereby ensuring the service life and reliability of the air guide plate 11.

[0058] like Figure 6 As shown, an embodiment of the present invention further provides an air conditioner 2, including a fan and the air conditioning air outlet structure 1 as described above.

[0059] In this embodiment, the air-conditioning outlet structure 1 is installed to the corresponding position of the air outlet of the air conditioner. Specifically, it can be fixed by snap 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 channels 131 to ensure uniform wind speed. At the same time, check whether the air guide plate 11 has surface defects, deformation and other problems. In addition, by simulating the air-conditioning operating environment, the reliability and durability of the air guide plate 11 are tested, such as conducting long-term operation tests under different temperature, humidity and wind speed conditions, observing whether the air guide plate 11 can work normally, and whether the air guide holes 12 and the air guide channels 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 holes punched inward to disperse the air flow, 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 control of the temperature 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. When the wind speed is low, 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 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, thereby reducing the user experience.

[0064] In different operation modes of the air conditioner, based on the principle that hot air rises and cold air sinks, the temperature can be better evenly distributed by controlling the rotation angle of the air guide plate 11. In the cooling mode, the cold air is guided to a suitable position to form a good temperature gradient indoors and avoid local overcooling; in the heating mode, the hot air is guided to different positions indoors to speed up indoor heat transfer, making the temperature of the entire indoor environment more uniform and improving the efficiency of the air conditioner.

[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 effectively, 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 operation mode of the air conditioner is the cooling mode, confirming 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 the intensity 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 less 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 scenarios where users do not have high requirements for cooling intensity or want soft air output. When the air conditioner detects that the air output gear is the first wind speed, the air conditioner will control the air guide plate 11 to rotate according to a preset first angle range, wherein the first angle range can be set to a smaller angle, such as ±15~30° (± represents the left and right air outlet directions, for example, the first angle range is ±15°, which means that the air guide plate 11 can rotate back and forth from 15° on the left to 15° on the right, or the first angle range is ±30°, which means that the air guide plate 11 can rotate back and forth from 30° on the left to 30° on the right). Within this angle range, the air flow rate can be increased so that when the air guide plate 11 blows out in a smaller range, the indoor temperature drops faster and more evenly. Among them, the first wind speed can be called low wind speed or medium wind speed during the specific implementation process. At the low wind speed or medium wind speed, the fan speed can be controlled to increase the predetermined speed (such as 100 revolutions), and then the air guide plate 11 can be controlled to rotate within the preset first angle range.

[0073] In S23, when the user switches the air outlet gear to the second wind gear, the strength of the gear is greater than the first wind gear, indicating that the user needs a stronger cooling effect, and the air conditioner controls the air guide plate 11 to rotate according to the preset second angle range. Since the second wind gear has a large strength, its corresponding second angle range must also be greater than the first angle range. For example, the second angle range can be set to ±30-90°. The flared protrusions on both sides of the air guide 13 can disperse the blown cold air to achieve the purpose of not blowing the wind on people, 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 distribute the cold air more evenly in a larger area, improve the cooling efficiency, and meet the needs of users in a larger space or when rapid cooling is required. Among them, the second wind gear can be called a high wind gear or a strong wind gear during the specific implementation process. At the high wind gear or the strong wind gear, the wind guide plate 11 rotates at a larger angle without blocking the blowing of a larger amount of air, and the bell-shaped mouths set on both sides of the wind guide plate can break up the airflow, thereby reducing the jet noise generated when the air flows through the bell-shaped mouth of the air guide part 13 at high speed, and making the wind blown out of the air conditioner more evenly distributed.

[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 air guide plate 11 rotates at a large angle, there will also 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 to 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 gear, 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, thereby 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 it is rotated at a small angle, and can avoid the buzzing sound caused by the vortex generated in the internal air duct due to the small opening and closing of the air guide plate 11, 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 Fig. 9 As shown, S20 includes:

[0076] S25, if the operation mode of the air conditioner is the heating mode, confirming 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 less 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, users pursue rapid temperature rise, so the air guide part 13 on the air guide plate 11 is controlled to reduce the temperature drop of the hot air as much as possible. Specifically, when the air conditioner detects that the air outlet gear is the first wind gear, the air conditioner will control the air guide plate 11 to rotate according to the preset fourth angle range, wherein the fourth angle range is set to be smaller, but due to the principle that hot air rises and cold air sinks, 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 bell mouth of the air guide part 13 is mainly used as a column to disperse the blown wind, so as to achieve the effect of not blowing people, so that the indoor temperature change is softer. Among them, the first wind gear can be called a low wind gear or a medium wind gear in the specific implementation process.

[0082] When switched to the second wind speed, the movement angle of the air guide plate 11 is larger, that is, the fifth angle range is larger than the fourth angle range, and can be set to ±30-90°, which will further reduce the working efficiency of the air guide hole 12, thereby maximizing the temperature of the air blown out by the air conditioner, and at the same time relying on the bell 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 wind speed can be called a high wind speed or a strong speed in the specific implementation process.

[0083] Similarly, when switching to the silent gear in the heating mode, the rotation angle of the air guide plate 11 is slightly reduced, which can be set to ±45~80°, and the fan speed is controlled to decrease, thereby achieving a silent effect.

[0084] The air outlet structure and control method of the air conditioner in the above embodiment can effectively improve the air flow rate. Compared with the traditional air guide plate, the overall indoor temperature can be adjusted more quickly, which solves the problem that the user has a poor experience of uneven indoor ambient temperature due to the short air supply distance of cold air in the low windshield mode. The fan speed can be increased by 100 rpm in the low gear to increase the air supply volume and airflow speed. Fig.10 and Fig.11 The simulation diagram of Fig.10 (a) and Fig.11 (a) is the air outlet channel of this embodiment, Fig.10 (b) and Fig.11 (b) It is the air outlet channel of the traditional air guide plate, achieving an effect similar to that of a windshield in a traditional air guide plate. At high wind speed, the air guide plate shape can be used to further organize the airflow, which has a positive impact on wind speed, air volume and airflow form, and there is no need to add additional motors or other driving mechanisms.
