Description

Technical Field

[0001] This utility model relates to the technical field, specifically to an air conditioner mesh cover and an air conditioner. Background Technology

[0002] The air conditioner mesh cover is a key component installed on the surface of the air conditioner casing to guide and rectify the airflow at the outlet, directly affecting the user experience and operational performance. As a major air resistance component, its design must consider multiple technical indicators: structural parameters are related to airflow output efficiency and operating noise; excessive flow resistance will lead to airflow reduction and increased energy consumption; and an unreasonable structure can easily cause airflow turbulence. It must have sufficient strength and rigidity, with a safety margin to cope with airflow impact and external forces during disassembly and assembly, ensuring long-term reliability. At the same time, it must strictly adhere to safety standards, control the gap between the ribs, and avoid safety hazards caused by the test finger contacting the internal fan blades.

[0003] In existing technologies, to balance flow resistance control and rectification effect, air conditioning grilles often adopt a configuration combining annular ribs and involute guide ribs. The annular ribs ensure structural stability, while the involute guide ribs help to organize the fluid at the axial fan blade outlet. This achieves certain effects in reducing flow resistance and optimizing airflow distribution, and has become a common design in the industry.

[0004] However, there is at least one problem with the relevant technology: existing air conditioner grilles often use straight ribs. Because the straight ribs are not well adapted to the speed of the airflow, it is difficult to guide the airflow smoothly, which can easily cause airflow turbulence. This results in the outdoor unit fan generating a lot of noise when it is working, thereby reducing the user's comfort. Utility Model Content

[0005] The technical problem solved by this utility model is that existing air conditioner grilles often use straight ribs. Because the straight ribs are not well adapted to the speed of the airflow, it is difficult to guide the airflow smoothly, which easily causes airflow turbulence. This results in the outdoor unit fan generating a lot of noise when it is working, thereby reducing the user's comfort.

[0006] To solve the above-mentioned technical problems, on the one hand, the present invention provides an air conditioner mesh cover, which includes a mesh cover shell and a plurality of longitudinal ribs and a plurality of oblique ribs arranged intersectingly, with the two ends of the plurality of longitudinal ribs and / or the plurality of oblique ribs fixedly disposed on the mesh cover shell; Each of the multiple longitudinal ribs includes a windward section and a windward outlet section, and the inner side of the windward section is provided with a wave-shaped structure along the vertical direction; Here, the length of the windward section is defined as t1, and the distance between the crests and troughs of the wave-shaped structure is L. A =0.2t1~0.8t1, the wavelength between two adjacent troughs of the wave-shaped structure is L. B=0.6t1~3t1.

[0007] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: By setting a wave-shaped structure on the inner side of the windward section of the longitudinal rib, this solution is better able to adapt to the velocity distribution characteristics of the fan blade fluid than the traditional straight rib, forming a smooth airflow guide, thereby reducing airflow impact, airflow turbulence and eddy phenomena, thus avoiding noise generated by the outdoor unit fan during operation, and improving user comfort.

[0008] Furthermore, this scheme limits the distance between the crests and troughs of the wave-shaped structure to L. A =0.2t1~0.8t1, the wavelength between two adjacent troughs of the wave-shaped structure is L B =0.6t1~3t1, so as to ensure the airflow guiding effect and avoid the increase of flow resistance due to excessive structural protrusion or unreasonable wavelength, thus ensuring the air volume of the outdoor unit of the air conditioner, thereby achieving a balance between noise reduction and ensuring air volume output efficiency.

[0009] In one embodiment of this utility model, the air conditioner mesh cover is installed at a position opposite to the outdoor unit fan; The diameter of the outdoor unit fan blades is D, the length of the air conditioner mesh cover is L, and the width of the air conditioner mesh cover is H. Where L>D, H>D.

[0010] Compared with existing technologies, the technical effects achieved by this solution are as follows: By limiting the length and width of the air conditioner mesh cover to be greater than the blade diameter D of the outdoor unit fan, and by installing the air conditioner mesh cover corresponding to the outdoor unit fan, the airflow generated by the rotation of the outdoor unit fan can more fully cover the effective circulation area of ​​the mesh cover, reducing the compression and backflow losses caused by insufficient size of the air conditioner mesh cover, thereby reducing the flow resistance of the air conditioner mesh cover to the air outlet fluid; at the same time, through sufficient coverage of the air conditioner mesh cover, strong vortices are avoided from forming at the edge of the air conditioner mesh cover, further suppressing noise generation, thereby improving the heat dissipation performance of the outdoor unit and the user comfort.

[0011] In one embodiment of this utility model, the thickness of any one of the plurality of longitudinal ribs is 0.002L, and the first spacing between two adjacent longitudinal ribs is 0.008L to 0.01L; The thickness of any one of the multiple diagonal stiffeners is 0.004D to 0.005D, and the second spacing between two adjacent diagonal stiffeners is... .

[0012] Compared with existing technologies, the technical effects achieved by this solution are as follows: By setting the thickness of the longitudinal stiffeners to 0.002L and the thickness of the diagonal stiffeners to 0.004D~0.005D, this solution ensures both the strength and rigidity of the longitudinal stiffeners themselves and reduces their resistance to airflow. Furthermore, by controlling the first spacing between two longitudinal stiffeners to 0.008L~0.01L and the second spacing between two adjacent diagonal stiffeners to... This design avoids excessive compression or turbulence of airflow and reduces the resistance of the diagonal ribs to the fluid. As a result, the air conditioner mesh cover of this solution not only ensures the strength and rigidity of the longitudinal and diagonal ribs themselves, but also optimizes the airflow channel, ensuring the air volume and heat dissipation efficiency of the outdoor unit, and improving the operational stability of the outdoor unit and the user's comfort.

[0013] In one embodiment of this utility model, the length of the air outlet section is t2, and the length of any one of the multiple oblique ribs along the axial direction of the outdoor unit fan is t3. Where t2 = 0.06D ~ 0.1D, t3 = t1.

[0014] Compared with existing technologies, the technical effects achieved by this solution are as follows: By limiting the length t2 of the longitudinal rib outlet section to 0.06D to 0.1D, the airflow can obtain a smooth transition space in the outlet section after being rectified by the wave-shaped structure of the windward section, thus avoiding secondary turbulence at the end of the ribs. At the same time, the axial length t3 of the diagonal ribs is set to be equal to the length t1 of the windward section, ensuring that the diagonal ribs and the longitudinal ribs form a cooperative guiding structure, further reducing the resistance of the diagonal ribs to the fluid and ensuring the air volume and heat dissipation efficiency of the outdoor unit.

[0015] In one embodiment of this utility model, the air conditioner mesh cover is divided into a first region and a second region by the horizontal cross-section of the longitudinal ribs, with the first region located above the second region; The longitudinal stiffeners are twisted, and the twisting directions of the longitudinal stiffeners in the first region and the second region are opposite.

[0016] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: The existing air conditioner grille has a problem: the contact area between the straight ribs and the airflow of the fan blades is relatively large, which can easily increase the airflow resistance, resulting in a decrease in the air volume of the air conditioner grille and thus affecting the heat dissipation efficiency of the outdoor unit.

[0017] To address this, this solution divides the air conditioner grille into upper and lower sections, and sets the longitudinal ribs to be twisted in opposite directions. Compared to traditional straight ribs, the twisted longitudinal ribs reduce the contact area with the airflow from the fan blades, lowering airflow resistance and increasing the outdoor unit's air volume, thereby improving the outdoor unit's heat dissipation efficiency. At the same time, the reverse twisting structure can provide targeted guidance for the airflow in the upper and lower sections, streamlining turbulent airflow, reducing airflow impact and eddy current generation, further reducing flow resistance and operating noise, thus improving user comfort.

[0018] In one embodiment of this utility model, the angle between the windward section and the air outlet section on the first center line of the first region is α, and the angle between the windward section and the air outlet section on the second center line of the second region is β. Where α=β, and the angle between the first center line and the angle between the second center line are in opposite directions.

[0019] Compared with existing technologies, the technical effects achieved by this solution are as follows: By setting the angle α between the windward section and the air outlet section of the longitudinal ribs in the first region and the angle β between the second center line of the second region to be equal and opposite in direction, the twisted longitudinal rib structure is made symmetrical and the force is balanced. This ensures the strength and rigidity of the longitudinal ribs and also provides a precise and coordinated guiding effect for the airflow in the first and second regions. This further reduces the fluid resistance of the longitudinal ribs, increases the air volume of the outdoor unit, and improves the heat dissipation efficiency of the outdoor unit.

[0020] In one embodiment of this utility model, the included angle between the first center line and the second center line is in the range of 10° to 20°.

[0021] Compared with existing technologies, the technical effects achieved by this solution are as follows: By setting the angle between the first centerline and the second centerline to a range of 10° to 20°, this solution avoids situations where the longitudinal rib structure strength decreases and flow resistance increases due to an excessively large angle, or where the noise reduction effect cannot be achieved due to an excessively small angle. This allows the longitudinal ribs to maintain their own strength and rigidity while working in conjunction with the reverse twisting structure to reduce airflow impact and eddy current generation, thereby enhancing the noise reduction effect and achieving simultaneous optimization of airflow and quietness performance. This, in turn, improves the stability of outdoor unit operation and user comfort.

[0022] In one embodiment of this utility model, the air conditioner mesh cover is provided with a first air outlet area, which corresponds to the location of the outdoor unit fan, and the diagonal ribs are provided in the first air outlet area.

[0023] Compared with the existing technology, the technical effect achieved by adopting this technical solution is as follows: This solution increases the connection strength between multiple longitudinal ribs and the mesh shell by setting the diagonal ribs in the first air outlet area corresponding to the outdoor unit fan position, thereby increasing the support strength of the longitudinal ribs.

[0024] In one embodiment of this utility model, the air conditioner mesh cover is provided with a first air outlet area and a second air outlet area, the second air outlet area surrounding the outer edge of the first air outlet area; The first air outlet area corresponds to the location of the outdoor unit's fan; Diagonal ribs are installed in the first and second air outlet areas.

[0025] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: By setting a first air outlet area and a second air outlet area in the air conditioner mesh cover, the air conditioner mesh cover can achieve full-area air outlet, increase the air volume of the outdoor unit, reduce the risk of condensation, and prevent condensation from entering the outdoor unit and damaging the internal components of the outdoor unit, thereby extending the service life of the outdoor unit.

[0026] On the other hand, this utility model also provides an air conditioner, which includes: The outdoor unit is equipped with an outdoor unit fan, and an air conditioner mesh cover as described in any of the above examples is installed opposite the outdoor unit fan. The indoor unit is connected to the outdoor unit via pipes.

[0027] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: it can achieve the technical effects corresponding to any of the above examples, which will not be elaborated here.

[0028] By adopting the technical solution of this utility model, the following technical effects can be achieved: (1) The air conditioner mesh cover provided by this utility model has a wave-shaped structure set on the inner side of the windward section of the longitudinal rib. Compared with the traditional straight rib, it can better adapt to the speed distribution characteristics of the fan blade fluid and form a smooth airflow guide, thereby reducing the generation of airflow impact, airflow turbulence and eddy phenomenon, so as to avoid the outdoor unit fan from generating noise when working, thereby improving the user's comfort. (2) The air conditioner mesh cover provided by this utility model limits the distance between the crests and troughs of the wave-shaped structure to L. A =0.2t1~0.8t1, the wavelength between two adjacent troughs of the wave-shaped structure is L B =0.6t1~3t1, so as to ensure the airflow guiding effect and avoid the increase of flow resistance due to excessive structural protrusion or unreasonable wavelength, thus ensuring the air volume of the outdoor unit of the air conditioner, thereby achieving a balance between noise reduction and ensuring air volume output efficiency.

[0031] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0032] like Figures 1 to 15 As shown, this utility model provides an air conditioner mesh cover, which includes a mesh cover shell 100 and a plurality of intersecting longitudinal ribs 200 and a plurality of diagonal ribs 300. The two ends of the plurality of longitudinal ribs 200 and / or the plurality of diagonal ribs 300 are fixedly disposed on the mesh cover shell 100. Each of the plurality of longitudinal ribs 200 includes a windward section 210 and an air outlet section 220. The inner side of the windward section 210 is provided with a wave-shaped structure 211 in the vertical direction. The length of the windward section 210 is defined as t1, and the distance between the crest 211a and the trough 211b of the wave-shaped structure 211 is L. A =0.2t1~0.8t1, the wavelength between two adjacent troughs 211b of the wave-shaped structure 211 is L B =0.6t1~3t1.

[0033] Specifically, this solution incorporates a wave-shaped structure 211 on the inner side of the windward section 210 of the longitudinal rib 200. Compared to traditional straight ribs, this structure is better suited to the velocity distribution characteristics of the fan blade fluid, providing smooth airflow guidance and reducing airflow impact, turbulence, and eddy currents. This helps prevent noise from the outdoor unit fan during operation and improves user comfort.

[0034] Furthermore, this scheme limits the distance between the crest 211a and the trough 211b of the wave-shaped structure 211 to L. A =0.2t1~0.8t1, the wavelength between two adjacent troughs 211b of the wave-shaped structure 211 is L B =0.6t1~3t1, so as to ensure the airflow guiding effect and avoid the increase of flow resistance due to excessive structural protrusion or unreasonable wavelength, thus ensuring the air volume of the outdoor unit of the air conditioner, thereby achieving a balance between noise reduction and ensuring air volume output efficiency.

[0035] It should be noted that the air conditioner mesh cover is installed on the outdoor unit and is positioned opposite to the fan blades of the outdoor unit. When the air conditioner mesh cover is installed on the outdoor unit, the side closer to the fan blades is the inner side (the inner side of the windward section 210 is the side of the windward section 210 closer to the fan blades).

[0036] like Figure 1 and Figure 2 As shown, in one embodiment of this utility model, the air conditioner mesh cover is installed at a position opposite to the outdoor unit fan; the diameter of the outdoor unit fan blade is D, the length of the air conditioner mesh cover is L, and the width of the air conditioner mesh cover is H; wherein, L>D, H>D.

[0037] Specifically, this solution limits the length and width of the air conditioner grille to be greater than the diameter D of the outdoor unit fan blades, and installs the grille corresponding to the outdoor unit fan. This allows the airflow generated by the outdoor unit fan to more fully cover the effective flow area of ​​the grille, reducing airflow compression and backflow losses caused by insufficient grille size. This reduces the flow resistance of the grille to the air outlet. At the same time, the sufficient coverage of the grille prevents the formation of strong vortices at the edge of the grille, further suppressing noise generation and improving the outdoor unit's heat dissipation performance and user comfort.

[0038] like Figure 1 and Figure 2 As shown, in one embodiment of this utility model, the thickness of any one of the plurality of longitudinal ribs 200 is 0.002L, and the first spacing between two adjacent longitudinal ribs 200 is 0.008L to 0.01L; the thickness of any one of the plurality of oblique ribs 300 is 0.004D to 0.005D, and the second spacing between two adjacent oblique ribs 300 is... .

[0039] Specifically, this solution sets the thickness of the longitudinal stiffener 200 to 0.002L and the thickness of the diagonal stiffener 300 to 0.004D~0.005D, thus ensuring both the strength and rigidity of the longitudinal stiffener 200 and reducing its resistance to airflow. Furthermore, by controlling the first spacing between two longitudinal stiffeners 200 to 0.008L~0.01L, and the second spacing between two adjacent diagonal stiffeners 300 to... This avoids excessive compression or turbulence of airflow and reduces the resistance of the diagonal ribs 300 to the fluid. Thus, the air conditioner mesh cover of this solution not only ensures the strength and rigidity of the longitudinal ribs 200 and the diagonal ribs 300, but also optimizes the airflow channel, ensuring the air volume and heat dissipation efficiency of the outdoor unit, and improving the operational stability of the outdoor unit and the user's comfort.

[0040] like Figures 2 to 6 As shown, in one embodiment of this utility model, the length of the air outlet section 220 is t2, and the length of any one of the plurality of inclined ribs 300 along the axial direction of the outdoor unit fan is t3; wherein, t2=0.06D~0.1D, t3=t1.

[0041] Specifically, this solution limits the length t2 of the air outlet section 220 of the longitudinal rib 200 to 0.06D to 0.1D, so that after the airflow is rectified by the wave-shaped structure 211 of the windward section 210, it can obtain a smooth transition space in the air outlet section 220, avoiding secondary turbulence at the end of the rib. At the same time, the axial length t3 of the diagonal rib 300 is set to be equal to the length t1 of the windward section 210, ensuring that the diagonal rib 300 and the longitudinal rib 200 form a cooperative guiding structure, further reducing the resistance of the diagonal rib 300 to the fluid, and ensuring the air volume and heat dissipation efficiency of the outdoor unit.

[0042] like Figures 2 to 10 As shown, in one embodiment of the present invention, the air conditioner mesh cover is divided into a first region 400 and a second region 500 by the horizontal cross-section of the longitudinal rib 200, with the first region 400 located above the second region 500; the longitudinal rib 200 is twisted, and the twisting direction of the longitudinal rib 200 in the first region 400 is opposite to that in the second region 500.

[0043] Specifically, existing air conditioner grilles have a problem: the contact area between the straight ribs and the airflow of the fan blades is relatively large, which can easily increase the airflow resistance, leading to a decrease in the airflow of the air conditioner grille and thus affecting the heat dissipation efficiency of the outdoor unit.

[0044] To address this, this solution divides the air conditioner grille into two sections, a first section 400 and a second section 500, and sets the longitudinal ribs 200 to be twisted in opposite directions. Compared with traditional straight ribs, the twisted longitudinal ribs 200 reduce the contact area with the airflow of the fan blades, lower airflow resistance, and increase the air volume of the outdoor unit, thereby improving the heat dissipation efficiency of the outdoor unit. At the same time, the reverse twisted structure can provide targeted guidance for the airflow in the upper and lower sections, streamlining turbulent airflow, reducing airflow impact and eddy current generation, further reducing flow resistance and operating noise, and thus improving user comfort.

[0045] like Figures 2 to 14 As shown, in one embodiment of this utility model, the angle between the windward section 210 and the air outlet section 220 along the first center line of the first region 400 is α, and the angle between the windward section 210 and the air outlet section 220 along the second center line of the second region 500 is β; where α = β, and the directions of the angle between the first center line and the angle between the second center line are opposite (wherein, Figures 12 to 14 The dashed line S represents the centerline between the windward section 210 and the air outlet section 220.

[0046] Specifically, this solution sets the angle α between the windward section 210 and the air outlet section 220 of the longitudinal rib 200 and the first center line of the first region 400 and the second center line of the second region 500 to be equal and opposite in direction. This makes the twisted longitudinal rib 200 structure symmetrical and stress-balanced, ensuring both the strength and rigidity of the longitudinal rib 200 and creating a precise and coordinated guiding effect on the airflow in the first region 400 and the second region 500. This further reduces the fluid resistance of the longitudinal rib 200, increases the air volume of the outdoor unit, and improves the heat dissipation efficiency of the outdoor unit.

[0047] like Figures 2 to 10 As shown, in one embodiment of this utility model, the angle between the first centerline and the second centerline ranges from 10° to 20°.

[0048] Specifically, this solution sets the angle between the first centerline and the second centerline to a range of 10° to 20°. This avoids situations where the longitudinal rib 200's structural strength decreases and flow resistance increases due to an excessively large angle, or where the noise reduction effect cannot be achieved due to an excessively small angle. As a result, the longitudinal rib 200 maintains its own strength and rigidity while working in synergy with the reverse twisting structure to reduce airflow impact and eddy current generation, thereby enhancing the noise reduction effect and achieving simultaneous optimization of airflow and quietness performance. This, in turn, improves the outdoor unit's operational stability and user comfort.

[0049] like Figure 2 As shown, in one embodiment of this utility model, the air conditioner mesh cover is provided with a first air outlet area 600, which corresponds to the location of the outdoor unit fan, and the diagonal ribs 300 are provided in the first air outlet area 600.

[0050] Specifically, this solution increases the connection strength between the multiple longitudinal ribs 200 and the mesh housing 100 by setting the diagonal ribs 300 in the first air outlet area 600 corresponding to the outdoor unit fan position, thereby increasing the support strength of the longitudinal ribs 200.

[0051] like Figure 15 As shown, in another embodiment of this utility model, the air conditioner mesh cover is provided with a first air outlet area 600 and a second air outlet area 700, the second air outlet area 700 surrounding the outer edge of the first air outlet area 600; the first air outlet area 600 corresponds to the location of the outdoor unit fan; the diagonal ribs 300 are provided in the first air outlet area 600 and the second air outlet area 700.

[0052] Specifically, this solution enables the air conditioner mesh cover to provide airflow over the entire area by setting a first air outlet zone 600 and a second air outlet zone 700. This increases the airflow of the outdoor unit, reduces the risk of condensation, and prevents condensation from entering the outdoor unit and damaging its internal components, thereby extending the service life of the outdoor unit.

[0053] On the other hand, this utility model also provides an air conditioner, which includes an outdoor unit and an indoor unit; the outdoor unit is provided with an outdoor fan, and an air conditioner mesh cover as described in any of the above examples is provided at a position opposite to the outdoor fan; the indoor unit and the outdoor unit are connected by pipes.

[0054] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
