Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a fan grille structure and an air conditioner. Background Technology

[0002] The top of a ceiling-mounted air conditioner is connected to the mounting surface, drawing in air from the bottom and blowing it out from the side.

[0003] In the prior art, air conditioners are provided with air inlets and air outlets, and at least one of the air inlets and air outlets is equipped with a baffle to rectify the airflow.

[0004] However, existing air vents tend to result in lower airflow and higher noise levels in air conditioners. Utility Model Content

[0005] This application provides a wind grille structure and an air conditioner to achieve the effect of increasing airflow and reducing noise in the air conditioner.

[0006] In a first aspect, embodiments of this application provide a windshield structure, including:

[0007] A frame, used to enclose the air vents of an air conditioner;

[0008] The first grid bar, and multiple first grid bars are provided, with the multiple first grid bars spaced apart along a first direction within the frame;

[0009] The second grid bar is provided in multiple ways. The multiple second grid bars are spaced apart in the frame along the second direction, and each second grid bar is intersected and connected to each first grid bar.

[0010] At least one of the first and second grilles protrudes toward the side of the frame away from the air vent.

[0011] In one possible implementation, the wind grating structure provided in this application embodiment has first grating bars spaced apart along the width direction of the frame and extending along the length direction of the frame;

[0012] The second grid bars are spaced apart along the length of the frame and extend along the width of the frame.

[0013] In one possible implementation, the wind grid structure provided in this application embodiment has the same spacing between the first grid bars and the same spacing between the second grid bars.

[0014] In one possible implementation, the second grid bar of the wind grid structure provided in this application embodiment is arc-shaped.

[0015] In one possible implementation, the wind grid structure provided in this application embodiment has the first grid bar arranged at intervals along the arcuate extension direction of the second grid bar.

[0016] In one possible implementation, the wind grating structure provided in this application embodiment has at least a portion of the first grating strips arranged at an angle relative to the frame.

[0017] In one possible implementation, the wind grid structure provided in this application embodiment has the first grid bar tilting direction symmetrical with respect to the middle of the second grid bar.

[0018] In one possible implementation, the wind grating structure provided in this application embodiment has a first grating bar with an inclination angle of greater than or equal to 25° and less than or equal to 30° relative to the frame.

[0019] In one possible implementation, the distance between the apex of the arc-shaped protrusion of the second grid bar and the frame of the wind grid structure provided in this application is greater than or equal to 8mm and less than or equal to 10mm.

[0020] Secondly, embodiments of this application provide an air conditioner, including an air conditioner body and any of the aforementioned air vent structures disposed on the air conditioner body.

The first vent bars are spaced apart along a first direction, and the second vent bars are spaced apart along a second direction and intersect with the first vent bars. At least one of the first and second vent bars protrudes towards one side of the frame. This allows the air vent structure to protrude at least partially relative to the air conditioner body, making the ventilation area of ​​the air vent structure larger than the air outlet area. This increases the contact area between the air vent structure and the air, improving the airflow of the air conditioner. Furthermore, the increased ventilation area allows for more thorough air rectification, reducing airflow turbulence, lowering air conditioner noise, achieving a wind-increasing and noise-reducing effect, and improving the user experience.

[0037] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. In the absence of conflict, the following embodiments and features can be combined with each other.

[0039] In the prior art, air conditioners are provided with air inlets and air outlets, and at least one of the air inlets and air outlets is equipped with a baffle to rectify the airflow.

[0040] However, the ventilation area of ​​existing air vents is usually set to be the same as the air inlet or outlet area of ​​the air conditioner, and the rectification effect when the airflow passes through is poor, which easily results in a small air volume and a large noise of the air conditioner.

[0041] To overcome the deficiencies in the prior art, the present application provides a louver structure and air conditioner. The louver structure includes a frame, a plurality of first louvers, and a plurality of second louvers. The first louvers are spaced apart along a first direction, and the second louvers are spaced apart along a second direction and intersect with the first louvers. At least one of the first and second louvers protrudes towards one side of the frame. This allows the louver structure to protrude at least partially relative to the air conditioner body, making the ventilation area of ​​the louver structure larger than the air outlet area. This increases the contact area between the louver structure and the air, improving the airflow of the air conditioner. Furthermore, the increased ventilation area allows for more thorough air rectification, reducing airflow turbulence, lowering air conditioner noise, achieving a wind-increasing and noise-reducing effect, and improving the user experience.

[0042] The present invention will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the present invention.

[0043] Reference Figures 1 to 5 As shown, this application embodiment provides a wind grating structure 100, including:

[0044] Frame 110, frame 110 is used to enclose the air vent of the air conditioner;

[0045] Multiple first grid bars 120 are provided, and the multiple first grid bars 120 are spaced apart along a first direction within the frame 110;

[0046] The second grid 130 is provided in multiple ways. The multiple second grid 130 are spaced apart in the frame 110 along the second direction, and each second grid 130 is cross-connected with each first grid 120.

[0047] At least one of the first grille 120 and the second grille 130 protrudes toward the side of the frame 110 away from the air vent.

[0048] It is understandable that, taking a ceiling-mounted air conditioner as an example, the top of the air conditioner body 200 is connected to the indoor ceiling or other mounting surface. An air inlet 210 is provided at the bottom of the air conditioner body 200, and an air outlet 220 is provided on the side of the air conditioner body 200. The air inlet 210 and the air outlet 220 are connected by an air duct, and an axial fan 230 is rotatably installed in the air duct. By rotating the axial fan 230, airflow can enter the air duct from the air inlet 210 and be blown out from the air outlet 220. The frame 110 of the air grille structure 100 provided in this application embodiment is used to connect with the air outlet of the air conditioner body. For example, the frame 110 can be installed at the air inlet 210 or at the air outlet 220, and this application does not limit this.

[0049] Multiple first grid bars 120 are arranged sequentially at intervals along a first direction within the frame 110, and multiple second grid bars 130 are arranged sequentially at intervals along a second direction, such that the second grid bars 130 intersect with the first grid bars 120. Thus, multiple grids can be formed within the frame 110 by the first grid bars 120 and the second grid bars 130. When airflow passes through the grids, it can be rectified by the grids.

[0050] In this configuration, at least one of the first grille 120 and the second grille 130 is configured to protrude toward the side of the frame 110 away from the air conditioner body 200, thereby causing the grille to protrude at least partially from the air conditioner body. This increases the contact area between the grille and the airflow, making it larger than the air outlet area of ​​the air conditioner body, thereby increasing the airflow volume. Furthermore, the grille can more fully rectify the airflow, more effectively dividing and guiding the airflow passing through the grille, which helps to improve the airflow distribution and flow state, and may thus improve the performance of the air conditioner.

[0051] Therefore, the air vent structure 100 provided in this embodiment includes a frame 110, a plurality of first vent bars 120, and a plurality of second vent bars 130. The first vent bars 120 are spaced apart along a first direction, and the second vent bars 130 are spaced apart along a second direction and intersect with the first vent bars 120. At least one of the first vent bars 120 and the second vent bars 130 protrudes towards the side facing the frame 110. In this way, the air vent structure 100 can be at least partially protruding relative to the air conditioner body, so that the ventilation area of ​​the air vent structure 100 is larger than the air outlet area, thereby increasing the contact and flow area between the air vent structure 100 and the air, improving the air volume of the air conditioner, and because the ventilation area of ​​the air vent structure 100 is increased, the rectification of air by the air vent structure 100 is more complete, reducing the degree of airflow turbulence, reducing the noise of the air conditioner, achieving the effect of increasing airflow and reducing noise in the air conditioner, and improving the user experience.

[0052] Reference Figures 3 to 5 As shown, the first grid bars 120 are spaced apart along the width direction of the frame 110 and extend along the length direction of the frame 110;

[0053] The second grid bars 130 are spaced apart along the length of the frame 110 and extend along the width of the frame 110.

[0054] It is understandable that by setting the first and second directions in this way, the first grille 120 can be arranged at intervals along the width direction of the frame 110, and the second grille 130 can be arranged at intervals along the length direction of the frame 110. This makes the air grille structure 100 clearer and more compact, which is convenient for subsequent design and manufacturing. It also helps to reasonably arrange the position and spacing of the first grille 120 and the second grille 130 according to the specific size and layout of the air conditioner, effectively ensuring the air-enhancing and noise-reducing effect of the air grille structure 100.

[0055] It is understandable that, since the length direction of the air grating structure 100 is aligned with the axial direction of the axial fan 230 inside the air conditioner body 200, and the width direction of the air grating structure 100 is aligned with the radial direction of the axial fan 230, this arrangement of the extension directions of the first grating bar 120 and the second grating bar 130 allows the first grating bar 120 to extend along the axial direction of the axial fan 230, and the second grating bar 130 to extend along the radial direction of the axial fan 230. This makes the air grating structure 100 fit more closely with the axial fan 230, forming a crisscrossing grid structure, further enhancing the airflow rectification effect of the air grating structure 100 and improving the uniformity and stability of the airflow.

[0056] In some embodiments, refer to Figures 3 to 5 As shown, the spacing between the first grid bars 120 is consistent, and the spacing between the second grid bars 130 is consistent.

[0057] This configuration allows for more uniform ventilation across the grids of the air grating structure, effectively ensuring the rectification effect.

[0058] In some embodiments, refer to Figures 3 to 5 As shown, the second grid bar 130 is arc-shaped.

[0059] Understandably, since the second grid 130 extends radially along the axial fan 230, setting the second grid 130 to be arc-shaped protrusion can make the second grid 130 fit the axial fan 230 more closely.

[0060] Furthermore, the arc-shaped protrusion can effectively reduce the resistance of airflow when it passes through the grid, so that the airflow can pass through the wind grid structure 100 more smoothly, thereby reducing the noise of airflow when it passes through the grid and increasing the air volume.

[0061] Furthermore, refer to Figures 3 to 5 As shown, the first grid bar 120 is arranged at intervals along the arc-shaped extension direction of the second grid bar 130.

[0062] It is understandable that by arranging the first grid bars 120 at arc intervals along the second grid bars 130, a height difference can be generated between the first grid bars 120 and the frame 110 in the thickness direction, thereby further expanding the contact area between the grid and the airflow.

[0063] This allows the arc-shaped protrusions of the first grille 120 and the second grille 130 in the air grating structure 100 to be matched more precisely, thereby adjusting the airflow path and further optimizing the airflow distribution to improve the airflow enhancement and noise reduction effect of the air conditioner.

[0064] Furthermore, in some embodiments, reference is made to Figures 3 to 5 As shown, at least a portion of the first grid bar 120 is inclined relative to the frame 110.

[0065] Understandably, since the axial fan 230 is cylindrical, when the axial fan 230 rotates, the airflow converges into the air inlet 210 along each radial direction of the axial fan 230. Therefore, setting part of the first grid bar 120 to be inclined relative to the frame 110 can make the first grid bar 120 less resistant to the airflow and better rectifying effect.

[0066] In specific implementation, refer to Figures 3 to 5 As shown, the tilt direction of the first grid bar 120 is symmetrical with respect to the middle of the second grid bar 130.

[0067] This configuration ensures that the tilt direction of the first grid bar 120 is completely aligned with the airflow direction, which can guide the airflow to flow more concentratedly toward the axial fan 230 and improve the rectification efficiency of the grid structure 100. It also helps to reduce turbulence and noise.

[0068] Among them, reference Figures 3 to 5 As shown, the tilt angle α of the first grid bar 120 relative to the frame 110 is greater than or equal to 25° and less than or equal to 30°.

[0069] It should be noted that the tilt angle α of the first grid bar 120 relative to the plane where the frame 110 is located is greater than or equal to 25° and less than or equal to 30°. Correspondingly, the tilt angle (complementary angle of α) of the first grid bar 120 relative to the tangential direction of the plane where the frame 110 is located is greater than or equal to 60° and less than or equal to 65°.

[0070] According to simulation, the tilt angle of the first grid bar 120 relative to the frame 110 is limited to 25° to 30°. Within this angle range, the tilted grid bar can better guide the airflow, while optimizing both air volume and noise.

[0071] For example, the tilt angle α of the first grid bar 120 relative to the normal of the plane where the frame 110 is located can be set to 30°, that is, the tilt angle (complementary angle of α) of the first grid bar 120 relative to the tangential direction of the plane where the frame 110 is located is 60°. Alternatively, the tilt angle α of the first grid bar 120 relative to the normal of the plane where the frame 110 is located can be set to 27°, that is, the tilt angle (complementary angle of α) of the first grid bar 120 relative to the tangential direction of the plane where the frame 110 is located is 63°. This application does not limit this.

[0072] Furthermore, in some embodiments, reference is made to Figures 3 to 5 As shown, the distance H between the vertex of the arc-shaped protrusion of the second grid bar 130 and the frame 110 is greater than or equal to 8 mm and less than or equal to 10 mm.

[0073] It is understandable that limiting the height of the protruding apex of the second grid bar 130 can effectively limit the curvature of the second grid bar 130, so as to ensure that the second grid bar 130 can effectively affect the airflow, but will not be too prominent and affect the overall structural stability and installation convenience of the wind grid structure 100.

[0074] For example, according to simulation, limiting the height of the protrusion apex of the second grid 130 to 8mm to 10mm can effectively reduce the airflow volume increase and noise reduction effect of the wind grid structure 100. The height of the protrusion apex of the second grid 130 can be set to 9mm, but this application does not limit it.

[0075] Reference Figures 1 to 5 As shown, this application embodiment also provides an air conditioner, including an air conditioner body 200 and a wind grille structure 100 of any of the above embodiments disposed on the air conditioner body 200.

[0076] This application provides an air conditioner with a louver structure 100. The louver structure 100 includes a frame 110, a plurality of first louvers 120, and a plurality of second louvers 130. The first louvers 120 are spaced apart along a first direction, and the second louvers 130 are spaced apart along a second direction and intersect with the first louvers 120. At least one of the first louvers 120 and the second louvers 130 protrudes towards the side facing the frame 110. This allows the louver structure 100 to protrude at least partially relative to the air conditioner body 200, making the ventilation area of ​​the louver structure 100 larger than the air outlet area. This increases the contact area between the louver structure 100 and the air, improving the airflow of the air conditioner. Furthermore, the increased ventilation area of ​​the louver structure 100 allows for more thorough air rectification, reducing airflow turbulence, lowering air conditioner noise, achieving a wind-increasing and noise-reducing effect, and improving the user experience.
