TECHNICAL FIELD

[0001] The utility model relates to air conditioning technical field especially relates to a deflector adjusting structure. BACKGROUND

[0002] In the prior art, in order to make air conditioner produce vortex air flow and realize the effect of preventing straight blowing, it is usually realized by modifying the deflector. For example, external deflector or integrated type anti-straight blowing design, these methods can adjust the air direction to a certain extent, but often need manual operation of the user, and there are condensation, dripping water and other problems, affect the use experience. In addition, these designs usually need customized deflector, increase the production cost and installation complexity.

[0003] In order to realize more efficient vortex air flow, some manufacturers redesign the middle frame and internal parts of air conditioner. For example, adopt layer recursive type air flow softening technology, through three section type air outlet design and jet turbulent flow to disrupt the air direction, so that air forms more soft air flow distribution in the room. However, this design needs to change the internal structure of air conditioner completely, including air outlet, air duct, air wheel and other key components, not only long design cycle, but also need high precision manufacturing and assembly process, further push up the design cost. SUMMARY

[0004] In order to overcome at least one defect of the prior art described above, the utility model provides a deflector adjusting structure, which can solve the problem that the middle frame and internal parts of air conditioner need to be redesigned in order for air conditioner to have vortex air flow and anti-straight blowing function.

[0005] The technical scheme adopted by the utility model to solve the problem is:

[0006] A deflector adjusting structure is assembled in an air conditioner, comprising:

[0007] A first deflector is rotatably assembled in the air conditioner and located at the air outlet of the air conditioner, and the first deflector is connected with a first driver.

[0008] A second deflector is rotatably assembled at the bottom of the air outlet of the air conditioner.

[0009] Wherein, the second deflector is located below the first deflector.

[0010] By adopting the above scheme, the design of the first air deflector rotatingly assembled to the air conditioner provides a structural basis for the generation of vortex air flow. The second air deflector assembled to the bottom of the air outlet plate can guide the air flow to vertical air outlet, thereby effectively avoiding the direct blowing of cold or warm air to the human body and reducing the discomfort. The first air deflector assembled to the air conditioner does not need to improve the existing air conditioner middle frame, avoids complex internal structure adjustment, reduces material consumption and processing difficulty, and also shortens the research and development cycle. In combination with the setting of the second air deflector, a structural basis can be provided for the generation of vortex air flow.

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

[0012] By adopting the above scheme, when the first air deflector is arranged along the length direction (i.e. transverse direction) of the air conditioner, it serves as a transverse air deflector and can effectively guide the air flow in the up-down direction. This design enables cold or hot air to be more evenly distributed to different heights of the room, reduces the temperature difference between the upper and lower layers of the room, and thus improves the overall comfort.

[0013] When the first air deflector is arranged along the height direction (i.e. longitudinal direction) of the air conditioner, it serves as a longitudinal air deflector and can effectively guide the air flow in the left-right direction. This design expands the range of the wind, enabling the air to more widely cover each corner of the room and improving the uniformity and efficiency of air flow.

[0014] Further, a third air deflector is arranged outside the panel, and the third air deflector has a gap with the superimposed frame to form an air duct.

[0015] By adopting the above scheme, the third air deflector is arranged outside the panel, and the third air deflector has a gap with the superimposed frame, which can guide the horizontal air outlet of the air conditioner, thereby achieving the possibility of multiple air outlets.

[0016] Further, a superimposed frame is arranged, the first air deflector is assembled to the corresponding position of the superimposed frame and the air outlet, the superimposed frame is arranged between the third air deflector and the panel, the middle part of the superimposed frame is recessed towards the panel to form a groove, and the third air deflector is located in the groove.

[0017] By adopting the above scheme, the first air deflector is assembled with the superimposed frame, without the need to improve the existing air conditioner middle frame, avoiding complex internal structure adjustment, reducing material consumption and processing difficulty, and shortening the research and development cycle. Meanwhile, the third air deflector is located in the groove, which can more effectively guide the flow direction of the airflow. The airflow guided by the third air deflector will form horizontal air outlet through the groove wall, which significantly reduces the possibility of cold air directly blowing to the human body, achieves the effect of preventing direct blowing, and improves the comfort of the user.

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

[0019] By adopting the above scheme, when the cold airflow passes through the groove wall, the outer wall of the groove 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.

[0020] Further, the superimposed frame is provided with a avoiding port at the air outlet, the second air deflector is located at the avoiding port, and the second air deflector is connected with the groove wall.

[0021] By adopting the above scheme, by connecting the second air deflector with the groove wall, even if the superimposed frame is provided with an avoiding port at the air outlet, the function of vertical air outlet can be realized by adjusting the angle of the second air deflector on the basis of horizontal air outlet. This structure increases the flexibility of air conditioner air supply, meets the use requirements of different users in different scenes. The connection of the second air deflector with the groove wall on both sides of the avoiding port makes the second air deflector play the role of spacing the groove wall and guiding the airflow to be vertical, thereby maintaining the integrity of the superimposed frame structure, and also helps to improve the overall stability and durability of the air conditioner.

[0022] Further, the superimposed frame is provided with a connecting plate towards the avoiding port, and the first air deflector is rotationally connected with the connecting plate.

[0023] By adopting the above scheme, when the first air deflector is arranged along the length direction of the air conditioner (i.e. transversely), in order to ensure the stability and reduce the shaking during rotation, the connecting plate is arranged on the superimposed frame to provide a connecting point for the middle part of the first air deflector, which can effectively disperse the stress and torque generated during rotation of the first air deflector, 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 deflector, ensures that it remains flat during operation, and avoids affecting the uniformity of air flow due to shaking.

[0024] Further, the second air deflector is rotationally installed on the air conditioner, and the second air deflector is connected with a second driver.

[0025] By adopting the above scheme, the second air deflector is rotatably installed on the air conditioner and located at the bottom of the air outlet of the air conditioner, the second air deflector is further connected with a second driver, the second air deflector 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] Further, the first air deflector has a windward face, which is an end face towards the side of the air outlet, and the windward face is a plane or an arc face.

[0027] By adopting the above scheme, the windward face of the first air deflector is designed as a straight face or an arc face, providing users with diversified choices. The straight face design is simple and direct, suitable for scenes that require clear airflow direction or limited space. The arc face design is more flexible and variable, allowing adjustment of airflow distribution according to indoor environment and user preferences, achieving a more comfortable user experience.

[0028] Regardless of whether the windward face is a straight face or an arc face, the rotation of the first air deflector can generate vortex airflow to a certain extent. The arc face design can better guide airflow to generate vortex, thereby enhancing the effect of vortex airflow. Vortex airflow not only improves the mixing efficiency of indoor air, but also reduces the discomfort of direct airflow blowing on the human body, providing users with a more comfortable use environment.

[0029] Further, a temperature measurement module is further included, the temperature measurement module is connected with a temperature measurement probe, and the temperature measurement probe is arranged inside the air conditioner to monitor the temperature of the outlet air.

[0030] By adopting the above scheme, the temperature measurement probe can monitor the temperature of the outlet air, thereby facilitating adjustment of the amplitude and frequency of the motion of the first air deflector based on the temperature data monitored by the temperature measurement probe, ensuring the continuous output of vortex airflow, and thereby providing a basis for the vortex airflow function of the air conditioner.

[0031] Further, the second air deflector is rotatably installed on the air conditioner, and the second air deflector is connected with a second driver.

[0032] By adopting the above scheme, the second air deflector is rotatably installed on the air conditioner and located at the bottom of the air outlet of the air conditioner, the second air deflector is further connected with a second driver, the second air deflector 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.

[0033] The utility model further provides a kind of air deflector adjusting method, using the air deflector adjusting structure described above;

[0034] The bidirectional one-way distance of the reciprocating motion of the first air deflector is set as 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;

[0035] When the vortex air flow is needed, the value of the one-way distance A of the reciprocating movement of the first air deflector is controlled to match the wind speed, the gas density and the viscosity coefficient, so that the value of Re is controlled in the range of 90 to 200, 300 to 3*10 5 , and greater than 3*10 6 , so as to generate the vortex air flow.

[0036] By adopting the above scheme, by setting the bidirectional one-way distance A of the reciprocating movement of the first air deflector, and combining the parameters such as the wind speed v, the gas density p, the Reynolds number Re and the viscosity coefficient mu, the utility model can accurately control the generation condition of the vortex air flow. In particular, by adjusting the value of A to match the wind speed, the viscosity coefficient and the gas density at the time, the value of Re falls within a specific range (such as 90 to 200, 300 to 310^5, and greater than 310^6), so as to effectively generate the vortex air flow. This accurate control not only improves the air flow distribution efficiency of the air conditioner, but also enhances the mixing and convection of indoor air, and improves the overall comfort.

[0037] Further, the characteristic length is set as d, the frequency of the reciprocating movement of the first air deflector is f1, and the whole circle correction parameter K, wherein d=f1*A / K.

[0038] By adopting the above scheme, by setting the bidirectional one-way distance A of the reciprocating movement of the first air deflector, and combining the parameters such as the wind speed v, the gas density p, the Reynolds number Re and the viscosity coefficient mu, the utility model can accurately control the generation condition of the vortex air flow. In particular, by adjusting the value of A to match the wind speed, the viscosity coefficient and the gas density at the time, the value of Re falls within a specific range (such as 90 to 200, 300 to 310^5, and greater than 310^6), so as to effectively generate the vortex air flow. This accurate control not only improves the air flow distribution efficiency of the air conditioner, but also enhances the mixing and convection of indoor air, and improves the overall comfort.

[0039] In order to make up for the difference brought by the non-cylindrical shape of the first air deflector, the utility model introduces the whole circle correction parameter K, which is set according to experimental data and fluid mechanics principles, and is used for adjusting the calculation of the characteristic length d to ensure that the air outlet effect of the vortex air flow reaches the best state. By accurately adjusting the value of K, the fine control of the intensity and distribution range of the vortex air flow can be realized, and the use demand in different scenes can be met.

[0040] The introduction of the whole circle correction parameter K not only improves the accuracy of the vortex air flow effect, but also enhances the stability. In actual application, due to the change of environmental conditions and the running state of the air conditioner, the generation and maintenance of the vortex air flow may be affected to a certain extent. However, the existence of the whole circle correction parameter K enables the controller to adaptively adjust according to the actual situation, so as to maintain the continuous stability of the vortex air flow effect.

[0041] In summary, the air deflector adjusting structure provided by the utility model has the following technical effects:

[0042] 1. The first air deflector is rotatably assembled in the superposition frame structure, which provides a structural basis for the generation of vortex air flow. Through the rotary motion of the first air deflector, the air flow 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.

[0043] 2. The first air deflector is assembled in the superposition frame structure, which does not require adjustment of the existing air conditioner middle frame structure, and does not require complex improvement of the air conditioner middle frame. It not only reduces material consumption and processing difficulty, but also reduces production cost. At the same time, due to the avoidance of major adjustment of the internal structure, the research and development cycle is shortened, so that the product can be faster to the market.

[0044] 3. By setting the bidirectional single-pass distance A of the reciprocating motion of the first air deflector, and combining the parameters such as wind speed v, gas density p, Reynolds number Re and viscosity coefficient μ, the utility model can accurately control the generation conditions of vortex air flow. Especially by adjusting the value of A to match the wind speed, viscosity coefficient and gas density at that 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 air flow. This precise control not only improves the air flow distribution efficiency of the air conditioner, but also enhances the mixing and convection of indoor air, and improves the overall comfort.

[0045] 4. When the wind speed v, the gas density p or the 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 bidirectional single-pass distance of the reciprocating motion of the first air deflector, thereby realizing the effect of outputting vortex air flow of the air conditioner, and the air conditioner itself is also provided with a temperature sensor and other temperature measuring elements, so that in some embodiments, no additional parts need to be added to the air conditioner to improve the air conditioner, and the bidirectional single-pass distance of the reciprocating motion of the first air deflector can be dynamically adjusted according to the wind speed adjustment and the temperature adjustment, so that vortex air flow is output in various situations.

DETAILED DESCRIPTION

[0058] In order to better understand and implement, the following will be combined with the drawings of the utility model, the technical scheme in the embodiment of the utility model is clearly and completely described and discussed, obviously, only a part of the utility model described here, is not all examples, based on the embodiment in the utility model, all other examples obtained by the person skilled in the art without doing creative work, belong to the protection scope of the utility model.

[0059] In order to facilitate the understanding of the embodiment of the utility model, the following will be combined with the drawings to explain and illustrate the specific embodiment as an example, and each embodiment does not constitute the limitation of the embodiment of the utility model.

[0060] ​​In the description of the utility model, it is necessary to explain, the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the utility model.

[0061] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the utility model belongs. The terminology used in the specification of the utility model herein is only for the purpose of describing the specific embodiments and is not intended to limit the utility model.

[0062] Referring to Figures 1-11 The utility model discloses a kind of air deflector adjusting structure, assemble in air conditioner 5, wherein air deflector adjusting structure includes first air deflector 2 and second air deflector 3 first air deflector 2 rotation assembly in air conditioner 5, and located at the air outlet 52 of air conditioner 5, first air deflector 2 is connected with first driver 21, second air deflector 3 rotation assembly in the bottom of air outlet 52 of air conditioner 5, wherein, second air deflector 3 is below first air deflector 2.

[0063] Specifically, the first air deflector 2 is rotatably arranged on the air conditioner 5 and located at the air outlet 52 of the air conditioner 5, so as to facilitate the adjustment of the air outlet of the air conditioner 5 by the first air deflector 2. The first air deflector 2 is connected with the first driver 21, so that the first driver 21 can actively adjust the rotation of the first air deflector 2, thereby more finely adjusting the air outlet. The second air deflector 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 deflector 2 and the second air deflector 3, more directions of air outlet can be realized, such as ordinary air outlet, up and down air swing, 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 deflector 3 to swing back and forth at a small amplitude and a high frequency to generate a vortex airflow. According to the Karman vortex formula f = Sr(v / d), the frequency f of each single vortex of the vortex, the flow velocity v, the diameter d of the cylinder, the Strouhal number Sr, and the generation of the vortex airflow are closely related to the diameter (d value) of the disturbing body and the disturbing velocity. The design drives the first air deflector 2 to swing back and forth at a high frequency and a small amplitude through the first driver 21, which actually adjusts the "equivalent d value" dynamically, so that the vortex airflow can be induced at different wind speeds. Compared with the traditional fixed shape of the first air deflector 2, this dynamic adjustment mechanism has higher flexibility and adaptability. In the prior art, in order to generate a vortex airflow, the shape of the first air deflector 2 often needs to be designed for a specific wind speed, which greatly limits the application range of the vortex airflow. However, by adjusting the swing frequency and amplitude of the first air deflector 2, the design can match the multiple levels of wind speed preset by the air conditioner 5, ensuring that the vortex airflow can be effectively generated at each level of wind speed. This design breaks through the limitations of traditional technology and improves the application efficiency and universality of the vortex airflow.

[0064] Referring to Figures 1-4 In some embodiments, the first air deflector 2 is arranged along the length direction of the air conditioner 5, and / or the first air deflector 2 is arranged along the height direction of the air conditioner 5.

[0065] Specifically, the length direction of the air conditioner 5 refers to the direction in which the body of 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 body of the air conditioner 5. The first air deflector 2 can be arranged along the length direction (i.e., transversely) of the air conditioner 5, or the first air deflector 2 can be arranged along the height direction (i.e., longitudinally) of the air conditioner 5. The designer can choose to arrange the first air deflector 2 transversely or longitudinally according to the requirements, specifically:

[0066] When the first air deflector 2 is arranged along the length direction (i.e., transversely) of the air conditioner 5, it serves as a transverse air deflector and can effectively guide the airflow to move in the up-down direction. This design enables cold or hot air to be more evenly distributed to different heights in the room, reducing the temperature difference between the upper and lower layers of the room, thereby improving the overall comfort.

[0067] Of course, the generation of vortex air flow can also be realized by separately setting the first air deflector 2, as long as the swing amplitude and swing frequency of the first air deflector 2 are controlled.

[0068] Referring to Figures 1-4 As shown in the drawings, in some embodiments, the air deflector adjusting structure further comprises a third air deflector 4, which is arranged outside the panel 51 and has a gap with the air conditioner 5 to form an air duct.

[0069] Referring to Figures 5-7 and Figure 10 Specifically, the third air deflector 4 is arranged outside the panel 51 and has a gap with the air conditioner 5 to form an air duct, which facilitates the air flow guided to the third air deflector 4 to diffuse around the third air deflector 4, and the air flow guided and diffused by the third air deflector 4 realizes the effect of horizontal four-way air outlet through the guidance of the groove wall 12. This structure can significantly reduce the possibility of cold air directly blowing to the human body, achieve the effect of preventing direct blowing, and improve the comfort of users.

[0070] In some embodiments, the air conditioner 5 further comprises a superposition frame 1, the first air deflector 2 is assembled at the corresponding position of the superposition frame 1 and the air outlet 52, the superposition frame 1 is arranged between the third air deflector 4 and the panel 51, the middle part of the superposition frame 1 is recessed towards the panel 51 to form a groove 11, and the third air deflector 4 is located in the groove 11.

[0071] The superposition frame 1 provides a mounting carrier for the installation of the first air deflector 2 and other expanded types of components, thereby avoiding the problem of redesigning the middle frame of the air conditioner 5.

[0072] Further, referring to Figure 1 , Figures 5-7 As shown in the drawings, on the basis of the structure that the middle part of the superposition frame 1 is recessed towards the panel 51 to form a groove 11, the groove wall 12 of the groove 11 is a hollow structure. Specifically, when the cold air flow passes through the groove wall 12 of the groove 11, the outer wall of the groove wall 12 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.

[0073] Referring to Figures 1-4 As shown in the drawings, in some embodiments, the superposition frame 1 is provided with a avoiding port 13 at the air outlet 52, the second air deflector 3 is located at the avoiding port 13, and the second air deflector 3 is connected with the groove wall 12 of the groove 11.

[0074] Specifically, by connecting the second air deflector 3 with the groove wall 12 of the groove 11, even if the avoidance opening 13 is arranged at the air outlet 52 of the superposition frame 1, the vertical air outlet function can be realized by adjusting the angle of the second air deflector 3 on the basis of horizontal air outlet. The structure increases the flexibility of air supply of the air conditioner 5 and meets the use requirements of different users in different scenes. The connection of the second air deflector 3 with the groove wall 12 on both sides of the avoidance opening 13 makes the second air deflector 3 keep a distance from the groove wall 12 and guide the air flow to be vertically outlet, thereby maintaining the integrity of the structure of the superposition frame 1 and also helping to improve the overall stability and durability of the air conditioner 5.

[0075] Referring to Figures 2-4 In some embodiments, in order to improve the stability of the first air deflector 2 in high-frequency reciprocating motion, the superposition frame 1 is provided with a connecting plate 14 towards the avoidance opening 13, and the first air deflector 2 is rotationally connected with the connecting plate 14.

[0076] Specifically, when the first air deflector 2 is arranged along the length direction (i.e. transversely) of the air conditioner 5, in order to ensure the stability and reduce the shaking in the rotation process, the connecting plate 14 is arranged on the superposition frame 1 to provide a connecting point for the middle part of the first air deflector 2, which can effectively disperse the stress and moment generated in the rotation process of the first air deflector 2, thereby reducing the risk of bending or deformation caused by the excessive length. The design of the middle support greatly enhances the stability of the first air deflector 2, ensures that it remains flat during operation, and avoids affecting the uniformity of air flow due to shaking.

[0077] Referring to Figures 1-7 In some embodiments, the second air deflector 3 is rotationally installed on the air conditioner 5, and the second air deflector 3 is connected with a second driver 31.

[0078] Specifically, the second air deflector 3 is rotationally installed on the air conditioner 5 and located at the bottom of the air outlet 52 of the air conditioner 5, and the second air deflector 3 is further connected with the second driver 31, which drives the rotation of the second air deflector 3, referring to Figure 11 Thus, the vertical air outlet of the air conditioner 5 is realized, and the effect of preventing direct blowing is realized.

[0079] Referring to Figure 7 and Figure 9 In some embodiments, the first air deflector 2 has a windward face 22, which is an end face towards the side of the air outlet 52, and the windward face 22 is a plane or an arc face.

[0080] Specifically, the windward face 22 of the first air deflector 2 can be selected as a straight face or an arc face, providing users with diversified choices. The straight face design is simple and direct, suitable for scenarios that require clear airflow direction or limited space. The arc face design is more flexible and variable, capable of adjusting airflow distribution according to indoor environment and user preferences, achieving a more comfortable user experience.

[0081] Regardless of whether the windward face 22 is a straight face or an arc face, the rotation of the first air deflector 2 can generate a vortex street airflow to some extent. The arc face design can better guide airflow to generate vortexes, thereby enhancing the effect of the vortex street airflow. The vortex street airflow not only improves the mixing efficiency of indoor air but also reduces the discomfort of direct airflow blowing on the human body, providing users with a more comfortable use environment.

[0082] In some embodiments, the air deflector adjusting structure further comprises a temperature measurement module connected with a temperature measurement probe arranged inside the air conditioner 5 for monitoring the outlet air temperature.

[0083] Specifically, the temperature measurement probe can monitor the outlet air temperature, thereby facilitating the adjustment of the motion amplitude and frequency of the first air deflector 2 based on the temperature data monitored by the temperature measurement probe, ensuring the continuous output of the vortex street airflow, and thereby providing a basis for the vortex street airflow function of the air conditioner 5. The temperature measurement probe can be arranged at a place inside the air conditioner 5 where the outlet air temperature can be monitored according to requirements, and can be arranged close to the first air deflector 2 to make temperature monitoring more accurate, thereby ensuring the generation of the vortex street airflow.

[0084] Referring to Figure 9 The utility model also provides a kind of air deflector adjusting method using the above air deflector adjusting structure.

[0085] The bidirectional one-way distance of the reciprocating motion of the first air deflector 2 is set as 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.

[0086] When the vortex street airflow is needed, the one-way distance A of the reciprocating motion of the first air deflector 2 is controlled to match the wind speed, gas density and viscosity coefficient, so that the value of Re is controlled in the range of 90 to 200, 300 to 3*10 5 , and greater than 3*10 6 , thereby generating the vortex street airflow.

[0087] Specifically, first, the bidirectional one-way distance of the reciprocating motion of the first air deflector 2 is set as A, and the wind speed v, gas density ρ and viscosity coefficient μ are monitored or preset. These parameters are the basis for calculating the Reynolds number (Re).

[0088] According to the definition formula Re = p v A / m, the Reynolds number value 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 flow state of the fluid (laminar flow or turbulent flow).

[0089] Vortex air flow is usually generated within a specific Reynolds number range, such as 90 to 200, 300 to 3 x 10 5 , and greater than 3 x 10 6 . These ranges can ensure the stable generation of vortex air flow.

[0090] When the wind speed v, the gas density p, or the viscosity coefficient m 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 bidirectional one-way distance of the reciprocating motion of the first guide vane 2, and then the output effect of the vortex air flow of the air conditioner 5 is realized. The air conditioner 5 itself also has a temperature sensor and other temperature measuring elements, so in some embodiments, no additional parts need to be added to the air conditioner 5 to improve the air conditioner 5, and the bidirectional one-way distance of the reciprocating motion of the first guide vane 2 can be dynamically adjusted according to the wind speed adjustment and the temperature adjustment, so that the vortex air flow is output in various situations. Specifically, if the wind speed increases, the controller will increase the value of A to maintain Re within the appropriate range; on the contrary, if the wind speed decreases, the controller will decrease the value of A.

[0091] During the adjustment process, the controller will continuously calculate the Re value and make fine adjustments according to the actual feedback to ensure the continuous and stable generation of vortex air flow. This closed-loop control mechanism improves the response speed and adjustment accuracy of the controller.

[0092] According to the Karman vortex street formula, Re and Sr are positively correlated, so the larger the value of Re, the larger the value of f, and f is the vortex shedding frequency. Based on the above, the user can adjust the Re value as needed to improve the vortex shedding frequency and further improve the air flow mixing effect, and ultimately achieve the effect of accelerating refrigeration / heating.

[0093] The Sutherland formula is an important model used to describe the viscosity characteristics of gases in gas thermodynamics. It is widely used in the field of engineering, such as gas dynamics, fluid mechanics, and aerodynamics related to fluid mechanics. The specific relationship is:

[0094]

[0095] m is the air dynamic viscosity; m0 is the air dynamic viscosity at standard temperature; T is the temperature; T0 is the standard temperature (usually 273.15 K); S is the Sutherland constant.

[0096] In some embodiments, in order to further improve the accuracy of generating vortex air flow, the characteristic length is set as d, the frequency of the reciprocating movement of the first air deflector 2 is f1, and the whole circle correction parameter K, wherein d = f1*A / K.

[0097] Since the first air deflector 2 achieves the effect of an equivalent cylinder through swinging, but it is not a cylinder, there is a certain numerical difference, the utility model introduces the whole circle correction parameter K, which is set according to experimental data and fluid mechanics principles, used for adjusting the calculation of the characteristic length d, to ensure that the air outlet effect of the vortex air flow reaches the best state. By accurately adjusting the value of K, fine control of the intensity and distribution range of the vortex air flow 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 air flow effect, but also enhances its stability. In actual application, due to changes in environmental conditions and the running state of the air conditioner 5, the generation and maintenance of the vortex air flow may be affected to a certain extent. The existence of the whole circle correction parameter K enables the controller to adaptively adjust according to the actual situation, maintaining the continuous stability of the vortex air flow effect.

[0098] The introduction of the whole circle correction parameter K not only improves the accuracy of the vortex air flow effect, but also enhances its stability. In actual application, due to changes in environmental conditions and the running state of the air conditioner 5, the generation and maintenance of the vortex air flow may be affected to a certain extent. The existence of the whole circle correction parameter K enables the controller to adaptively adjust according to the actual situation, maintaining the continuous stability of the vortex air flow effect.

[0099] The value range of K is 0.5 to 2, and the specific value range of K can be adjusted according to the radian of the windward surface 22 of the first air deflector 2. When the radian of the windward surface 22 is closer to the turning arc line of the first air deflector 2 during movement, the value range is smaller, and vice versa. The value of K can also be corrected according to the frequency f1 of the reciprocating movement of the first air deflector 2 and the bidirectional one-way distance of the reciprocating movement of the first air deflector 2. The specific principle is the same as above, and will not be repeated here.

[0100] In this embodiment, the frequency of the reciprocating movement of the first air deflector 2 is thirty times per minute, the bidirectional one-way distance of the reciprocating movement of the first air deflector 2 is 90 mm, the turning radius of the first air deflector 2 is 35 mm, and the single-side turning angle of the first air deflector 2 is 45 degrees, which can generate relatively stable vortex air flow.

[0101] It should be noted that although the first air deflector 2 is not a cylinder through high-frequency small-amplitude reciprocating movement, this high-frequency small-amplitude movement can achieve a vortex air flow effect similar to a cylinder to some extent, thereby improving the mixing efficiency of the air flow and the uniformity of the indoor temperature.

[0102] The technical means disclosed in the utility model scheme are not limited to the technical means disclosed in the above-mentioned embodiments, and also include technical schemes composed of any combination of the above technical features. It should be pointed out that, for ordinary skilled persons in the technical field, under the premise of not departing from the principle of the utility model, a number of improvements and refinements can be made, and these improvements and refinements are also considered to be within the protection scope of the utility model.
