[0031] See also Figure 1-Figure 3 .
[0032] Some embodiments of the present application disclose an air outlet grille, comprising transverse bars 1 and vertical bars 2, wherein the transverse bars 1 are arranged in a horizontal direction and the vertical bars 2 are arranged in a vertical direction. A plurality of transverse bars 1 and a plurality of vertical bars 2 are combined to form a mesh structure, and the mesh holes of the mesh structure are used for gas to pass through.
[0033] In this solution, the cross section of the transverse bars 1 of the air outlet grille along the direction perpendicular to its own length is teardrop-shaped, and the teardrop shape has a large end and a small end, wherein the large end is located at the windward end of the transverse bars 1, and the small end is located at the leeward end of the transverse bars 1.
[0034] The windward end of the big end is the starting end of the big end, the end where the big end is connected to the small end is the end of the big end, and the end where the big end is connected to the small end is also the starting end of the small end, and the leeward end of the small end is the end of the small end. Figure 2 As shown, the thickness of the large end gradually increases from its starting end to its end, while the thickness of the small end gradually decreases from its starting end to its end, so that the thickness of the cross-section of the transverse bar 1 along the direction perpendicular to its own length is thickest at the connection between the large end and the small end, and the thickness at the starting end of the large end is much greater than the thickness at the end of the small end. It should be noted here that the transverse bar 1 has a flat structure, the width of the transverse bar 1 is the dimension from the starting end of the large end to the end of the small end, and the thickness of the transverse bar 1 is the dimension of the transverse bar 1 in the direction perpendicular to its own length and width.
[0035] In this solution, the thickness of the transverse grating 1 is smoothly transitioned from the starting end to the end of the large end, at the connection position between the large end and the small end, and from the starting end to the end of the small end, and tends to decrease smoothly, so as to reduce the wind resistance of the airflow passing through the transverse grating.
[0036] In the direction of gas flow, the transverse grid bar 1 is designed in a water drop shape. The airflow will first pass through the large end of the water drop shape and then pass through the small end of the water drop shape. The airflow resistance at the windward end is reduced, and at the same time, the vortex generated by the airflow at the leeward end is reduced, thereby reducing noise. Figure 2 As shown, the mesh structure composed of horizontal bars and vertical bars shows a trend of gradually increasing air outlet area, which is conducive to gas expansion, reduces wind resistance, and thus reduces air conditioning energy consumption.
[0037] The impeller of the axial flow fan of the outdoor unit rotates at a high speed, and the airflow rotates under the action of the impeller blades, and the rotation cuts out the transverse grille 1 when the air is discharged. In the related art, the air outlet grille is set in the horizontal direction, and the air outlet airflow will be blocked by the transverse grille 1, causing wind loss. The transverse grille 1 of this solution includes a first grille 11 and a second grille 12 located on both sides of the vertical central axis of the air outlet grille. The lengths of the first grille 11 and the second grille 12 are equal. The first grille 11 has a first torsion angle toward the first direction relative to the plane where the air outlet grille is located, and the second grille 12 has a second torsion angle toward the second direction relative to the plane where the air outlet grille is located, wherein the first direction and the second direction are opposite, so that the transverse grille 1 is twisted along its own length direction to conform to the rotation direction of the airflow, so as to achieve the purpose of reducing wind loss.
[0038] Preferably, the first torsion angle and the second torsion angle are as consistent as possible with the wind shear direction to achieve the best effect, and on the other hand, to reduce the wind noise.
[0039] The air outlet grille disclosed in this solution is designed to have a cross-section of the transverse bars 1 designed to be teardrop-shaped, and at the same time, the portions of the transverse bars 1 located on both sides of the vertical central axis of the air outlet grille are twisted according to the wind shear direction. The two cooperate to achieve the purpose of reducing airflow resistance and wind loss, thereby reducing air conditioning energy consumption.
[0040] In some embodiments, the air outlet grille may have only the transverse bars 1 in a teardrop-shaped cross section perpendicular to its own length, or both the transverse bars 1 and the vertical bars 2 may have a teardrop-shaped cross section perpendicular to their own length.
[0041] In an embodiment where the cross-sections of the transverse bars 1 and the vertical bars 2 along the direction perpendicular to their own lengths are both teardrop-shaped, the mesh structure formed by the combination of the transverse bars 1 and the vertical bars 2 has an air outlet area that gradually increases from the air inlet side to the air outlet side, which is conducive to gas expansion, reduces wind resistance, and thus reduces air conditioning energy consumption.
[0042] The teardrop shapes of the horizontal gratings 1 and the vertical gratings 2 may be the same or different.
[0043] In some embodiments, the distance between two adjacent transverse bars 1 or two adjacent vertical bars 2 is 7.8-8.5 mm. It should be noted that the mesh size of the mesh structure composed of the transverse bars 1 and the vertical bars 2 needs to be smaller than the size of a finger to prevent the user's finger from reaching into the device through the mesh and causing personal injury.
[0044] The cross section of the transverse bars 1 and / or the vertical bars 2 is in the shape of a teardrop. The thinner the teardrop shape is, the smaller the wind resistance of the transverse bars 1 and / or the vertical bars 2 is. Specifically, the height of the transverse bars 1 and / or the vertical bars 2 at the large end is h, and the width of the transverse bars 1 and / or the vertical bars 2 is l. The smaller the ratio of h / l is, the thinner the teardrop shape is, and the lower the wind resistance is. Therefore, on the basis of ensuring the strength of the transverse bars 1 and / or the vertical bars 2, the smaller the ratio of h / l is, the better. In some embodiments, the height of the transverse bars 1 and / or the vertical bars 2 at the large end is h, which is 4 mm, and the width of the transverse bars 1 and / or the vertical bars 2 is l, which is 8 mm. It should be noted here that h and l of the transverse bars 1 and / or the vertical bars 2 are not limited to the above embodiments, and can also be other sizes.
[0045] Optionally, the ratio h / l of the transverse bars 1 and / or the vertical bars 2 does not exceed 1 / 2.
[0046] In other embodiments, the length of the small end can be appropriately extended to increase the difference between the length of the small end and the length of the large end, that is, the length of the wind-guiding portion of the horizontal bars 1 and / or the vertical bars 2 is extended, and the length of the windward portion of the horizontal bars 1 and / or the vertical bars 2 is shortened, which can also reduce wind resistance.
[0047] Optionally, the length of the large end does not exceed 1 / 2 of the length of the small end.
[0048] In some embodiments, the height and length of the large end may be shortened simultaneously to achieve the purpose of reducing wind resistance.
[0049] In order to further reduce wind loss, in some embodiments, the windward end of the large end is arc-shaped and the leeward end of the small end is pointed, so as to reduce the vortex formed at the small end and reduce wind loss.
[0050] In some embodiments, the arc angle of the windward end of the large end is 120°-160°, and the angle of the small end is 10°-30°.
[0051] In some embodiments, the first torsion angles of the first bars 11 of two adjacent transverse bars 1 are the same, that is, the first torsion angles of the first bars 11 of all transverse bars 1 located on the first side of the vertical central axis of the air outlet grille are the same.
[0052] In some embodiments, the first torsion angles of the first bars 11 of two adjacent transverse bars 1 are different, that is, the first torsion angles of the first bars 11 of all transverse bars 1 located on the first side of the vertical central axis of the air outlet grille have multiple angles. Specifically, the first torsion angle can be designed according to the rotary cutting angle, and the first torsion angle changes gradually.
[0053] In some embodiments, the second torsion angles of the second bars 12 of two adjacent transverse bars 1 are the same, that is, the second torsion angles of the second bars 12 of all transverse bars 1 located on the second side of the vertical central axis of the air outlet grille are the same.
[0054] In some embodiments, the second torsion angles of the second bars 12 of two adjacent transverse bars 1 are different, that is, the second torsion angles of the second bars 12 of all transverse bars 1 located on the second side of the vertical central axis of the air outlet grille have multiple angles. Specifically, the second torsion angle can be designed according to the rotary cutting angle, and the second torsion angle changes gradually.
[0055] In some embodiments, the torsion angles of the first bar 11 and the second bar 12 of the same transverse bar 1 may be the same or different.
[0056] In an embodiment where the torsion angles of the first and second gratings 11 and 12 of the same transverse grating 1 are different, the first torsion angle of the first grating 11 and the second torsion angle of the second grating 12 are designed according to the rotary shear angle of the air outlet.
[0057] In some embodiments, the first twist angle and the second twist angle are 5°-20°.
[0058] Optionally, the first torsion angle and the second torsion angle are 10°-15°

[0061] In related technologies, such as Figure 1 As shown, the cross section of the horizontal grid bar 1 is a long strip with rounded ends. 3 / h, the air volume attenuation ratio is 7.8%;
[0062] In the embodiment in which the cross section of the transverse grid bar 1 is in the shape of a water drop, at a wind volume of 6949 m 3 / h, the air volume attenuation ratio is 6.3%, and the wind loss is reduced;
[0063] In the embodiment where the cross section of the transverse grating 1 is teardrop-shaped and the transverse grating 1 is located on both sides of the vertical center axis of the air outlet grille, the twist angle of the first grating 11 and the second grating 12 is 15°, at an air volume of 7002m 3 / h, the wind volume attenuation ratio is 5.9%, and the wind loss reduction is more obvious.
