Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air guide plate adjustment structure and an adjustment method. Background Art

[0002] In the prior art, in order to make the air conditioner generate vortex airflow and achieve the effect of preventing direct blowing, it is often achieved by modifying the air guide plate. For example, external air guide plates or integrated anti-direct blowing designs can adjust the air outlet direction to a certain extent, but they often require manual operation by the user, and there are problems such as condensation and dripping, which affect the user experience. In addition, these designs usually require customized air guide plates, which increases production costs and installation complexity.

[0003] In order to achieve more efficient vortex airflow, some manufacturers have redesigned the middle frame and internal components of the air conditioner. For example, the layered airflow softening technology is used to disrupt the airflow direction through a three-stage air outlet design and turbulent jets, so that the air forms a softer airflow distribution in the room. However, this design requires a complete change in the internal structure of the air conditioner, including key components such as the air outlet, air duct, and wind wheel. Not only does it have a long design cycle, but it also requires high-precision manufacturing and assembly processes, further pushing up the design cost. Summary of the invention

[0004] In order to overcome at least one of the defects of the above-mentioned prior art, the present invention provides an air guide plate adjustment structure and adjustment method, which can solve the problem in the prior art that in order for the air conditioner to have the functions of generating vortex airflow and preventing direct blowing, the middle frame of the air conditioner and the components inside the middle frame need to be redesigned.

[0005] The technical solution adopted by the present invention to solve the problem is:

[0006] An air guide plate adjustment structure, mounted on an air conditioner, comprising:

[0007] a first air guide plate, the first air guide plate being rotatably mounted on the air conditioner and located at an air outlet of the air conditioner, the first air guide plate being connected to a first driver;

[0008] A second air guide plate, the second air guide plate being rotatably mounted on the bottom of the air outlet of the air conditioner;

[0009] Wherein, the second air guide plate is located below the first air guide plate.

[0010] By adopting the above scheme, the design of the first air guide plate being rotatably mounted on the air conditioner provides a structural basis for the generation of vortex street airflow. The second air guide plate is mounted on the bottom of the air outlet plate, which can guide the airflow to the vertical outlet, thereby effectively preventing cold air or warm air from blowing directly onto the human body and reducing discomfort. The first air guide plate is mounted on the air conditioner, and there is no need to improve the existing air conditioner middle frame, which avoids complex internal structure adjustments, reduces material consumption and processing difficulty, and also shortens the research and development cycle. Combined with the setting of the second air guide plate, it can form a structural basis for the output of vortex street airflow.

[0011] Further, the first air guide plate is arranged along the length direction of the air conditioner, and / or the first air guide plate is arranged along the height direction of the air conditioner.

[0012] By adopting the above solution, when the first air guide plate is arranged along the length direction (i.e., the horizontal direction) of the air conditioner, it acts as a horizontal air guide plate and can effectively guide the airflow in the vertical direction. This design enables the cold air or hot air to be more evenly distributed to different heights of the room, reduces the temperature difference between the upper and lower floors of the room, and thus improves the overall comfort.

[0013] When the first air guide plate is arranged along the height direction (i.e., longitudinal direction) of the air conditioner, it acts as a longitudinal air guide plate and can effectively guide the airflow in the left and right directions. This design expands the range of wind action, allowing the air to more widely cover every corner of the room, and improves the uniformity and efficiency of air flow.

[0014] Furthermore, it also includes a third air guide plate, which is arranged on the outside of the panel, and there is a gap between the third air guide plate and the stacking frame to form an air duct.

[0015] By adopting the above scheme, the third air guide plate is set, and the third air guide plate is set on the outside of the panel. There is a gap between the third air guide plate and the superimposed frame, which can provide guidance for the horizontal air outlet of the air conditioner, thereby achieving multiple air outlet possibilities.

[0016] Furthermore, it also includes a superposition frame, the first air guide plate is assembled at the corresponding position of the superposition frame and the air outlet, the superposition frame is arranged between the third air guide plate and the panel, the middle part of the superposition frame is recessed toward the panel to form a groove, and the third air guide plate is located in the groove.

[0017] By adopting the above solution, the first air guide plate is assembled with the stacking frame, and there is no need to improve the existing air conditioner middle frame, which avoids complex internal structure adjustment, reduces material consumption and processing difficulty, and also shortens the research and development cycle. In addition, the third air guide plate is located in the groove, which can more effectively guide the direction of the airflow. The wind guided by the third air guide plate will form a horizontal outlet through the groove wall of the groove. This design significantly reduces the possibility of cold air blowing directly onto the human body, achieves the effect of preventing direct blowing, and improves the user's comfort.

[0018] Furthermore, the groove wall of the groove is a hollow structure.

[0019] By adopting the above solution, when the cold air flows through the groove wall, since the groove wall participates in guiding the air flow, its outer wall may be affected by the cold air flow and condensation may occur. The hollow structure can form an air insulation layer, thereby reducing the risk of condensation.

[0020] Furthermore, the stacking frame is provided with a avoidance opening at the air outlet, the second air guide plate is located at the avoidance opening, and the second air guide plate is connected with the groove wall of the groove.

[0021] By adopting the above solution, by connecting the second air guide plate with the groove wall, even if the stacking frame is provided with a avoidance opening at the air outlet, it can ensure that on the basis of horizontal air outlet, by adjusting the angle of the second air guide plate, the function of vertical air outlet can be achieved. This structure increases the flexibility of air supply of the air conditioner and meets the usage needs of different users in different scenarios. The second air guide plate is connected with the groove walls on both sides of the avoidance opening, so that the second air guide plate can play the role of spacing the groove wall and guiding the airflow to vertically discharge air, thereby maintaining the integrity of the stacking frame structure and helping to improve the overall stability and durability of the air conditioner.

[0022] Furthermore, the stacking frame is provided with a connecting plate toward the avoidance opening, and the first air guide plate is rotatably connected to the connecting plate.

[0023] By adopting the above scheme, when the first air guide plate is arranged along the length direction of the air conditioner (i.e., horizontally), due to its long length, in order to ensure its stability and reduce shaking during rotation, a connecting plate is arranged on the superimposed frame to provide a connection point for the middle part of the first air guide plate, which can effectively disperse the stress and torque generated by the first air guide plate during rotation, thereby reducing the risk of bending or deformation caused by excessive length. The design of the middle support greatly enhances the stability of the first air guide plate, ensuring that it remains straight during operation, and avoiding shaking to affect the uniformity of air flow.

[0024] Furthermore, the second air guide plate is rotatably mounted on the air conditioner, and the second air guide plate is connected to a second driver.

[0025] By adopting the above scheme, the second air guide plate is rotatably installed on the air conditioner and is located at the bottom of the air outlet of the air conditioner. The second air guide plate is also connected to a second driver, and the second air guide plate is driven to rotate by the second driver, thereby realizing vertical air outlet of the air conditioner and achieving the effect of preventing direct blowing.

[0026] Furthermore, the first wind guide plate has a windward surface, the windward surface is an end surface facing the air outlet, and the windward surface is a plane or a curved surface.

[0027] By adopting the above solution, the windward surface of the first air guide plate is designed to be straight or curved, providing users with a variety of choices. The straight design is simple and direct, suitable for scenes where the airflow direction needs to be clear or the space is limited; while the curved design is more flexible and can adjust the airflow distribution according to the indoor environment and user preferences, achieving a more comfortable user experience.

[0028] Regardless of whether the windward surface is straight or curved, the rotation of the first air guide plate can generate vortex airflow to a certain extent. The curved surface design can better guide the airflow to generate vortices due to its special curved surface shape, thereby enhancing the effect of vortex airflow. Vortex airflow can not only improve the mixing efficiency of indoor air, but also reduce the discomfort of airflow blowing directly onto the human body, bringing users a more comfortable use environment.

[0029] Furthermore, it also includes a temperature measuring module, the temperature measuring module is connected to a temperature measuring probe, and the temperature measuring probe is arranged inside the air conditioner to monitor the outlet air temperature.

[0030] By adopting the above scheme, the temperature measuring probe can monitor the outlet air temperature, so that it is convenient to adjust the movement amplitude and frequency of the first air guide plate in combination with the temperature data monitored by the temperature measuring probe, so as to ensure the continuous output of vortex airflow, thereby providing a basis for the vortex airflow function of the air conditioner.

[0031] The present invention also provides a method for adjusting an air deflector plate, which adopts the above-mentioned air deflector plate adjusting structure;

[0032] The bidirectional one-way distance of the reciprocating motion of the first air guide plate is set to A, the wind speed is v, the gas density is ρ, the Reynolds number is Re, and the viscosity coefficient is μ, wherein Re=ρvA / μ;

[0033] When vortex airflow is required, the value of Re is controlled between 90 and 200, 300 and 3*10 by controlling the value of the one-way distance A of the reciprocating motion of the first air guide plate to match the wind speed, gas density and viscosity coefficient. 5 , and greater than 3*10 6 range, thereby generating vortex airflow.

[0034] By adopting the above scheme, by setting the two-way one-way distance A of the reciprocating motion of the first air guide plate, and combining parameters such as wind speed v, gas density ρ, Reynolds number Re and viscosity coefficient μ, the present invention can accurately control the generation conditions of vortex street airflow. In particular, by adjusting the value of A to match the wind speed, viscosity coefficient and gas density at the time, the Re value falls within a specific range (such as 90 to 200, 300 to 310^5, and greater than 310^6), thereby effectively generating vortex street airflow. This precise control not only improves the airflow distribution efficiency of the air conditioner, but also enhances the mixing and convection of indoor air, thereby improving the overall comfort.

[0035] Further, the characteristic length is set to d, the frequency of the reciprocating motion of the first air guide plate is f1, and the full circle correction parameter is K, wherein d=f1*A / K.

[0036] By adopting the above scheme, by setting the first air guide plate to reciprocate at a high frequency f1 and a small amplitude A, although the first air guide plate is not a cylinder due to the high-frequency and small-amplitude reciprocating motion, this high-frequency and small-amplitude motion mode can achieve a vortex street airflow effect similar to that of a cylinder to a certain extent, thereby improving the mixing efficiency of the airflow and the uniformity of the indoor temperature.

[0037] In order to make up for the difference caused by the non-cylindrical shape of the first air guide plate, the present invention introduces a full circle correction parameter K, which is set according to experimental data and fluid mechanics principles and is used to adjust the calculation of the characteristic length d to ensure that the air outlet effect of the vortex airflow reaches the best state. By accurately adjusting the K value, the intensity and distribution range of the vortex airflow can be finely controlled to meet the use requirements in different scenarios.

[0038] The introduction of the full-circle correction parameter K not only improves the accuracy of the vortex airflow effect, but also enhances its stability. In practical applications, the generation and maintenance of vortex airflow may be affected to a certain extent due to changes in environmental conditions and air conditioning operating conditions. The existence of the full-circle correction parameter K enables the controller to make adaptive adjustments based on actual conditions to maintain the continuous stability of the vortex airflow effect.

[0039] In summary, the wind deflector adjustment structure and adjustment method provided by the present invention have the following technical effects:

[0040] 1. The structure in which the first air guide plate is rotatably assembled on the superimposed frame provides a structural basis for the generation of vortex airflow. Through the rotational movement of the first air guide plate, the airflow can be guided to form a specific vortex pattern, thereby enhancing the mixing and convection of indoor air and improving the heat exchange efficiency of the air conditioner.

[0041] 2. The first air guide plate is assembled on the structure of the superimposed frame, and there is no need to adjust the existing air conditioner middle frame structure, and there is no need to make complex improvements to the air conditioner middle frame. This not only reduces material consumption and processing difficulty, but also reduces production costs. At the same time, since major adjustments to the internal structure are avoided, the R&D cycle is also shortened, allowing the product to be brought to market faster.

[0042] 3. By setting the two-way one-way distance A of the reciprocating motion of the first air guide plate, and combining parameters such as wind speed v, gas density ρ, Reynolds number Re and viscosity coefficient μ, the present invention can accurately control the conditions for generating vortex street airflow. In particular, by adjusting the value of A to match the wind speed, viscosity coefficient and gas density at the time, the Re value is made to fall within a specific range (such as 90 to 200, 300 to 310^5, and greater than 310^6), thereby effectively generating vortex street airflow. This precise control not only improves the airflow distribution efficiency of the air conditioner, but also enhances the mixing and convection of indoor air, thereby improving the overall comfort.

[0043] 4. When the wind speed v, gas density ρ or viscosity coefficient μ changes, the controller can know the wind speed through the preset wind speed, and the gas density is calculated based on the temperature monitored by the temperature probe, and the viscosity coefficient is calculated according to the Sutherland formula, so that only one temperature probe can be used to accurately adjust the two-way one-way distance of the reciprocating motion of the first air guide plate, thereby achieving the effect of the air conditioner outputting vortex airflow, and the air conditioner itself will also be provided with temperature measuring elements such as temperature sensors. Therefore, in some embodiments, the air conditioner can be improved without adding any components to the inside of the air conditioner, and the two-way one-way distance of the reciprocating motion of the first air guide plate can be dynamically adjusted according to the wind speed adjustment and temperature adjustment, so as to achieve vortex airflow output in a variety of situations.

DETAILED DESCRIPTION

[0056] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described and discussed below in conjunction with the accompanying drawings of the present invention. Obviously, what is described here is only a part of the examples of the present invention, not all the examples. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0057] In order to facilitate the understanding of the embodiments of the present invention, the following will be further explained by taking specific embodiments as examples in conjunction with the drawings, and each embodiment does not constitute a limitation on the embodiments of the present invention.

[0058] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0059] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0060] See also Figure 1-Figure 11 As shown, the present invention discloses an air guide plate adjustment structure, which is assembled on an air conditioner 5, wherein the air guide plate adjustment structure includes a first air guide plate 2 and a second air guide plate 3. The first air guide plate 2 is rotatably assembled on the air conditioner 5 and is located at the air outlet 52 of the air conditioner 5. The first air guide plate 2 is connected to a first driver 21, and the second air guide plate 3 is rotatably assembled on the bottom of the air outlet 52 of the air conditioner 5, wherein the second air guide plate 3 is located below the first air guide plate 2.

[0061] Specifically, the first air guide plate 2 is rotatably mounted on the air conditioner 5 and is located at the air outlet 52 of the air conditioner 5, so that the first air guide plate 2 can adjust the air outlet of the air conditioner 5. The first air guide plate 2 is connected to the first driver 21, so that the first driver 21 can actively adjust the rotation of the first air guide plate 2, so as to more finely adjust the air outlet. The second air guide plate 3 is arranged at the bottom of the air outlet 52 of the air conditioner 5, which can guide the airflow. Through the cooperation of the first air guide plate 2 and the second air guide plate 3, more directions of air outlet can be achieved, such as ordinary air outlet, up and down swing air outlet, vertical air outlet, etc. The bottom of the air outlet 52 refers to the bottom of the air conditioner 5, that is, the bottom surface of the air conditioner 5 when the air conditioner 5 is normally assembled. More importantly, the first driver 21 can also drive the second air guide plate 3 to swing back and forth with a small amplitude and high frequency to generate vortex airflow. According to the Karman vortex formula f=Sr(v / d), the frequency f of each single vortex in the vortex, the flow velocity v, the cylinder diameter d, the Strouhal number Sr, the generation of vortex airflow is closely related to the diameter (d value) and the turbulent velocity of the turbulent body. This design drives the first air guide plate 2 to swing back and forth with a high frequency and a small amplitude through the first driver 21, which is actually dynamically adjusting the "equivalent d value", so that vortex airflow can be induced at different wind speeds. This dynamic adjustment mechanism has higher flexibility and adaptability than the first air guide plate 2 with a traditional fixed shape. In the prior art, in order to generate vortex airflow, it is often necessary to design the shape of the first air guide plate 2 for a specific wind speed, which greatly limits the scope of application of vortex airflow. However, this design can match the multi-level wind speed preset by the air conditioner 5 by adjusting the swing frequency and amplitude of the first air guide plate 2, ensuring that vortex airflow can be effectively generated at each level of wind speed. This design breaks the limitations of traditional technology and improves the application efficiency and wide application of vortex airflow.

[0062] See also Figure 1-Figure 4 As shown in some embodiments, the first air guide plate 2 is disposed along the length direction of the air conditioner 5 , and / or the first air guide plate 2 is disposed along the height direction of the air conditioner 5 .

[0063] Specifically, the length direction of the air conditioner 5 refers to the direction in which the air conditioner 5 extends along its longest side, and the height direction of the air conditioner 5 refers to the vertical direction from the bottom to the top of the air conditioner 5. The first air guide plate 2 can be arranged along the length direction (i.e., the horizontal direction) of the air conditioner 5, and the first air guide plate 2 can also be arranged along the height direction (i.e., the vertical direction) of the air conditioner 5. The designer can choose whether to arrange the first air guide plate 2 horizontally or vertically according to the needs, specifically:

[0064] When the first air guide plate 2 is arranged along the length direction (i.e., the horizontal direction) of the air conditioner 5, it acts as a horizontal air guide plate and can effectively guide the airflow in the vertical direction. This design allows the cold air or hot air to be more evenly distributed to different heights of the room, reducing the temperature difference between the upper and lower floors of the room, thereby improving the overall comfort.

[0065] Of course, the generation of vortex airflow can also be achieved by separately providing a longitudinal first air guide plate 2 , as long as the swing amplitude and swing frequency of the first air guide plate 2 are controlled.

[0066] See also Figure 1-Figure 4 As shown, in some embodiments, the air guide plate adjustment structure further includes a third air guide plate 4, which is disposed on the outside of the panel 51, and there is a gap between the third air guide plate 4 and the air conditioner 5 to form an air duct.

[0067] See also Figure 5-Figure 7 and Fig.10 As shown, specifically, the third air guide plate 4 is arranged on the outside of the panel 51, and there is a gap between the third air guide plate 4 and the air conditioner 5 to form an air duct, which facilitates the airflow guided to the third air guide plate 4 to diffuse to the surroundings along the third air guide plate 4. The diffused airflow guided by the third air guide plate 4 is guided by the groove wall 12 to achieve the effect of horizontal four-sided wind outlet. This structure can significantly reduce the possibility of cold air blowing directly to the human body, achieve the effect of preventing direct blowing, and improve the user's comfort.

[0068] In some embodiments, the air conditioner 5 also includes a superimposed frame 1, the first air guide plate 2 is assembled at the corresponding position of the superimposed frame 1 and the air outlet 52, the superimposed frame 1 is arranged between the third air guide plate 4 and the panel 51, and the middle part of the superimposed frame 1 is recessed toward the panel 51 to form a groove 11, and the third air guide plate 4 is located in the groove 11.

[0069] The stacking frame 1 provides a mounting carrier for the first air guide plate 2 and other expansion types of components, thereby avoiding the problem of the need to redesign the middle frame of the air conditioner 5.

[0070] Further, see Figure 1 , Figure 5-7As shown, based on the structure that the middle part of the stacking frame 1 is recessed toward the panel 51 to form the groove 11, the groove wall 12 of the groove 11 is a hollow structure. Specifically, when the cold air flows through the groove wall 12 of the groove 11, since the groove wall 12 participates in the work of guiding the airflow, its outer wall may be affected by the cold airflow and condensation may occur. The hollow structure can form an air insulation layer, thereby reducing the risk of condensation.

[0071] See also Figure 1-Figure 4 As shown, in some embodiments, the stacking frame 1 is provided with a avoidance opening 13 at the air outlet 52 , the second air guide plate 3 is located at the avoidance opening 13 , and the second air guide plate 3 is connected to the groove wall 12 of the groove 11 .

[0072] Specifically, by connecting the second air guide plate 3 with the groove wall 12 of the groove 11, even if the stacking frame 1 is provided with a avoidance opening 13 at the air outlet 52, it is possible to ensure that on the basis of horizontal air outlet, by adjusting the angle of the second air guide plate 3, the function of vertical air outlet is achieved. This structure increases the flexibility of air supply of the air conditioner 5 and meets the use needs of different users in different scenarios. The second air guide plate 3 is connected with the groove wall 12 on both sides of the avoidance opening 13, so that the second air guide plate 3 can play the role of spacing the groove wall 12 and guiding the airflow to vertically discharge air, thereby maintaining the integrity of the structure of the stacking frame 1, and also helping to improve the overall stability and durability of the air conditioner 5.

[0073] See also Figure 2-Figure 4 As shown, in some embodiments, in order to improve the stability of the first air guide plate 2 in high-frequency reciprocating motion, the stacking frame 1 is provided with a connecting plate 14 toward the avoidance opening 13 , and the first air guide plate 2 is rotatably connected to the connecting plate 14 .

[0074] Specifically: when the first air guide plate 2 is arranged along the length direction (i.e., horizontally) of the air conditioner 5, due to its long length, in order to ensure its stability and reduce shaking during rotation, a connecting plate 14 is arranged on the superimposed frame 1 to provide a connection point for the middle part of the first air guide plate 2, which can effectively disperse the stress and torque generated by the first air guide plate 2 during rotation, thereby reducing the risk of bending or deformation caused by excessive length. The design of the middle support greatly enhances the stability of the first air guide plate 2, ensuring that it remains straight during operation, and avoiding shaking to affect the uniformity of air flow.

[0075] See also Figure 1-Figure 7 As shown, in some embodiments, the second air guide plate 3 is rotatably mounted on the air conditioner 5, and the second air guide plate 3 is connected to a second driver 31.

[0076] Specifically, the second air guide plate 3 is rotatably mounted on the air conditioner 5 and is located at the bottom of the air outlet 52 of the air conditioner 5. The second air guide plate 3 is also connected to a second driver 31, and the second air guide plate 3 is driven to rotate by the second driver 31. Fig.11As shown, vertical air outlet of the air conditioner 5 is achieved, thereby achieving the effect of preventing direct blowing.

[0077] See also Figure 7 and Fig. 9 As shown, in some embodiments, the first air guide plate 2 has a windward surface 22, the windward surface 22 is an end surface facing the air outlet 52, and the windward surface 22 is a plane or a curved surface.

[0078] Specifically, the windward surface 22 of the first air guide plate 2 can be straight or curved, providing users with a variety of choices. The straight design is simple and direct, suitable for scenes where the airflow direction needs to be clear or the space is limited; while the curved design is more flexible and can adjust the airflow distribution according to the indoor environment and user preferences to achieve a more comfortable user experience.

[0079] Regardless of whether the windward surface 22 is a straight surface or a curved surface, the rotation of the first air guide plate 2 can generate vortex airflow to a certain extent. The curved surface design can better guide the airflow to generate vortices due to its special curved surface shape, thereby enhancing the effect of the vortex airflow. The vortex airflow can not only improve the mixing efficiency of indoor air, but also reduce the discomfort caused by the airflow blowing directly onto the human body, thus providing a more comfortable use environment for users.

[0080] In some embodiments, the air guide plate adjustment structure further includes a temperature measuring module, the temperature measuring module is connected to a temperature measuring probe, and the temperature measuring probe is disposed inside the air conditioner 5 for monitoring the outlet air temperature.

[0081] Specifically, the temperature probe can monitor the outlet air temperature, so that the movement amplitude and frequency of the first air guide plate 2 can be adjusted in combination with the temperature data monitored by the temperature probe, so as to ensure the continuous output of the vortex airflow, thereby providing a basis for the vortex airflow function of the air conditioner 5. The temperature probe can be set in a place in the air conditioner 5 where the outlet air temperature can be monitored according to needs, and can be set close to the first air guide plate 2, so that the temperature monitoring is more accurate, thereby ensuring that the vortex airflow can be generated.

[0082] See also Fig. 9 As shown, the present invention also provides a method for adjusting an air guide plate, which adopts the above-mentioned air guide plate adjusting structure;

[0083] The bidirectional one-way distance of the reciprocating motion of the first air guide plate 2 is set to A, the wind speed is v, the gas density is ρ, the Reynolds number is Re, and the viscosity coefficient is μ, where Re=ρvA / μ;

[0084] When vortex airflow is required, the value of Re is controlled within the range of 90 to 200, 300 to 3*10 by controlling the value of the one-way distance A of the reciprocating motion of the first air guide plate 2 to match the wind speed, gas density and viscosity coefficient. 5 , and greater than 3*10 6 range, thereby generating vortex airflow.

[0085] Specifically, first, the bidirectional one-way distance of the reciprocating motion of the first air guide plate 2 is set to A, and the wind speed v, gas density ρ and viscosity coefficient μ are monitored or preset at the same time. These parameters are the basis for calculating the Reynolds number (Re).

[0086] According to the definition formula of Reynolds number Re=ρvA / μ, the Reynolds number under the current state is calculated in real time. The Reynolds number reflects the relative size between the inertial force and the viscous force when the fluid flows, and is an important basis for judging the fluid flow state (laminar flow or turbulent flow).

[0087] Vortex flow is usually generated within a specific Reynolds number range, such as 90 to 200, 300 to 3×10 5 , and greater than 3×10 6 These ranges can ensure the stable generation of vortex airflow.

[0088] When the wind speed v, gas density ρ or viscosity coefficient μ changes, the controller can know the size of the wind speed through the preset wind speed, the gas density is calculated based on the temperature monitored by the temperature probe, and the viscosity coefficient is calculated according to the Sutherland formula, so that only one temperature probe can be used to accurately adjust the two-way one-way distance of the reciprocating motion of the first air guide plate 2, thereby achieving the effect of the air conditioner 5 outputting vortex airflow, and the air conditioner 5 itself will also be provided with temperature sensors and other temperature measuring elements, so in some embodiments, it is not necessary to add any parts to the air conditioner 5 to improve the air conditioner 5, and the two-way one-way distance of the reciprocating motion of the first air guide plate 2 can be dynamically adjusted according to the wind speed adjustment and temperature adjustment, so as to achieve vortex airflow output in various situations. Specifically, if the wind speed increases, the controller will increase the value of A to maintain Re within a suitable range; conversely, if the wind speed decreases, the controller will decrease the value of A.

[0089] During the adjustment process, the controller will continuously calculate the Re value and make fine adjustments based on actual feedback to ensure the continuous and stable generation of vortex airflow. This closed-loop control mechanism improves the response speed and adjustment accuracy of the controller.

[0090] According to the Karman vortex street formula, Re and Sr are positively correlated, so the larger the Re value is, the larger the f is, where f is the vortex shedding frequency. Based on the above, the user can adjust the Re value as needed to increase the vortex shedding frequency, thereby further improving the airflow mixing effect and ultimately achieving the effect of accelerating cooling / heating.

[0091] Among them, the Sutherland formula is an important model used in gas thermodynamics to describe the viscosity characteristics of gases. In the engineering field, it is widely used in gas dynamics, fluid mechanics, aerodynamics and other fluid mechanics related fields. The specific relationship is:

[0092]

[0093] μ is the aerodynamic viscosity; μ0 is the aerodynamic viscosity at standard temperature; T is temperature; T0 is the standard temperature (usually 273.15K); S is the Sutherland constant.

[0094] In some embodiments, in order to further improve the accuracy of generating vortex airflow, the characteristic length is set to d, the frequency of the reciprocating motion of the first air guide plate 2 is f1, and the full circle correction parameter is K, wherein d=f1*A / K.

[0095] Since the first air guide plate 2 achieves the effect of an equivalent cylinder by swinging, but it is not a cylinder, there is a certain numerical difference. The present invention introduces a whole circle correction parameter K. This parameter is set according to experimental data and fluid mechanics principles, and is used to adjust the calculation of the characteristic length d to ensure that the air outlet effect of the vortex airflow reaches the best state. By accurately adjusting the K value, fine control of the vortex airflow intensity and distribution range can be achieved to meet the use requirements in different scenarios. The introduction of the whole circle correction parameter K not only improves the accuracy of the vortex airflow effect, but also enhances its stability. In actual applications, due to changes in environmental conditions and the operating state of the air conditioner 5, the generation and maintenance of the vortex airflow may be affected to a certain extent. The existence of the whole circle correction parameter K enables the controller to make adaptive adjustments according to actual conditions to maintain the continuous stability of the vortex airflow effect.

[0096] The introduction of the full circle correction parameter K not only improves the accuracy of the vortex airflow effect, but also enhances its stability. In practical applications, due to changes in environmental conditions and the operating state of the air conditioner 5, the generation and maintenance of the vortex airflow may be affected to a certain extent. The existence of the full circle correction parameter K enables the controller to make adaptive adjustments according to actual conditions to maintain the continuous stability of the vortex airflow effect.

[0097] The value range of K is 0.5 to 2. The specific value range of K can be adjusted according to the curvature of the windward surface 22 of the first air guide plate 2. When the curvature of the windward surface 22 is closer to the rotation arc of the first air guide plate 2 during movement, the value range is smaller, and vice versa. It can also be corrected according to the frequency f1 of the reciprocating motion of the first air guide plate 2 and the two-way one-way distance of the reciprocating motion of the first air guide plate 2. The specific principle is the same as above and will not be repeated here.

[0098] In this embodiment, the frequency of the reciprocating motion of the first air guide plate 2 is thirty times per minute, the bidirectional one-way distance of the reciprocating motion of the first air guide plate 2 is 90 mm, the rotation radius of the first air guide plate 2 is 35 mm, and the unilateral rotation angle of the first air guide plate 2 is 45 degrees, which can generate a relatively stable vortex airflow.

[0099] It should be noted that although the first air guide plate 2 is not a cylinder and performs high-frequency and small-amplitude reciprocating motion, this high-frequency and small-amplitude motion can achieve a vortex airflow effect similar to that of a cylinder to a certain extent, thereby improving the mixing efficiency of the airflow and the uniformity of the indoor temperature.

[0100] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above-mentioned technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also regarded as the protection scope of the present invention.
