[0032] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0033] The air outlet grille 100 of an air conditioner according to an embodiment of the present invention will be described below with reference to the accompanying drawings. As Figures 1-10 shown, the air outlet grille 100 of the air conditioner according to the embodiment of the present invention includes a plurality of ribs 1, and each rib 1 includes a body 11, a first diversion section 12, and a second diversion section 13.

[0034] The body 11 has an air inlet side 111 and an air outlet side 112 that are opposite to each other in the width direction of the rib 1. The first diversion section 12 is connected to the air inlet side 111 of the body 11, and the second diversion section 13 is connected to the air inlet side 111 of the body 11. The first diversion section 12 and the second diversion section 13 are arranged along the length direction of the rib 1. The first diversion section 12 and the second diversion section 13 of the air outlet grille 100 are located on both sides of the rotating shaft of the blower of the air conditioner.

[0035] The rib 1 has a first side and a second side opposite to each other in its thickness direction. The first diversion section 12 deflects towards the first side relative to the body 11, and the second diversion section 13 deflects towards the second side relative to the body 11. In other words, the first diversion section 12 and the second diversion section 13 deflect in opposite directions relative to the body 11, that is, the deflection direction of the first diversion section 12 relative to the body 11 is opposite to the deflection direction of the second diversion section 13 relative to the body 11.

[0036] When the blower of the air conditioner operates, the airflow blown by the rotating blower has a certain deflection angle in the horizontal direction. That is to say, under the rotation of the blower blades, the horizontal component of the velocity and the vertical component of the velocity of the airflow blown by the blower are not directly facing the air outlet grille (ribs), but have a certain deflection angle, and the deflection direction is the same as the rotation direction of the blower (blower blades). The profile line of the ribs of the air outlet grille in the related art is perpendicular to the vertical plane where the air outlet grille is located. As a result, the airflow blown by the blower impacts the air outlet grille and causes aerodynamic losses, thereby not only reducing the air outlet efficiency, but also increasing the aerodynamic noise.

[0037] By deflecting the first diversion section 12 and the second diversion section 13 in opposite directions relative to the body 11, and making the deflection directions of the first diversion section 12 and the second diversion section 13 correspond (match) to the rotation direction of the blower, the inclination directions of the first diversion section 12 and the second diversion section 13 can be made substantially consistent with the flow direction of the airflow. Thus, the angle of the airflow impacting the first diversion section 12 and the second diversion section 13 can be effectively reduced, so as to effectively reduce the impact force of the airflow on the first diversion section 12 and the second diversion section 13, thereby effectively reducing the aerodynamic losses and noise (as Figure 11 shown), significantly increasing the air volume, and significantly reducing the motor power of the blower (as Figure 12 shown).

[0038] Therefore, by using the air outlet grille 100 according to the embodiment of the present invention, the aerodynamic losses and noise can be effectively reduced, the air volume can be significantly increased, and the motor power of the blower can be significantly reduced.

[0039] The present invention also discloses an outdoor unit of an air conditioner. The outdoor unit of the air conditioner according to the embodiment of the present invention includes a blower and an air outlet grille 100. The first diversion section 12 and the second diversion section 13 of the air outlet grille 100 are located on both sides of the rotating shaft of the blower. The deflection directions of the first diversion section 12 and the second diversion section 13 correspond (match) to the rotation direction of the blower.

[0040] Correspondingly, the outdoor unit of the air conditioner according to the embodiment of the present invention has the advantages of small aerodynamic losses, low noise, large air volume, low motor power of the blower, and low energy consumption.

[0041] As Figures 1-10As shown, the air outlet grille 100 includes a plurality of ribs 1, and the plurality of ribs 1 are spaced apart in the thickness direction of the ribs 1. Optionally, the thickness direction of the ribs 1 may be consistent with the horizontal direction or the vertical direction. That is, the plurality of ribs 1 may be spaced apart in the horizontal direction or the vertical direction.

[0042] Each rib 1 includes a main body 11, a first diversion section 12, a transition section 14, and a second diversion section 13. The main body 11 may be straight, for example, the main body 11 is in the shape of a flat plate.

[0043] As Figures 2-5 shown, the first diversion section 12 is a straight section, for example, the first diversion section 12 is in the shape of a flat plate. As Figures 7-10 shown, the first diversion section 12 is an arc-shaped section, for example, the first diversion section 12 is in the shape of a circular arc. As Figures 2-5 shown, the second diversion section 13 is a straight section, for example, the second diversion section 13 is in the shape of a flat plate. As Figures 7-10 shown, the second diversion section 13 is an arc-shaped section, for example, the second diversion section 13 is in the shape of a circular arc.

[0044] The main body 11 has an air inlet side 111 and an air outlet side 112 that are opposite to each other in the width direction of the rib 1. For example, the width direction of the rib 1 is consistent with the front-rear direction, the fan is located behind the rib 1 (air outlet grille 100), and the air flow blown out by the fan flows through the air outlet grille 100 from the rear to the front. The air inlet side 111 of the main body 11 is the rear side of the main body 11, and the air outlet side 112 of the main body 11 is the front side of the main body 11.

[0045] As Figures 3-5 and Figures 8-10 shown, the first diversion section 12, the transition section 14, and the second diversion section 13 are all connected to the air inlet side 111 of the main body 11. The first diversion section 12, the transition section 14, and the second diversion section 13 are arranged along the length direction of the rib 1. That is, the transition section 14 is located between the first diversion section 12 and the second diversion section 13 in the length direction of the rib 1.

[0046] Optionally, the front side of the first diversion section 12 is connected to the rear side of the main body 11, the front side of the transition section 14 is connected to the rear side of the main body 11, and the front side of the second diversion section 13 is connected to the rear side of the main body 11. The front side of the transition section 14 is the air outlet side 144 of the transition section 14, and the rear side of the transition section 14 is the air inlet side 143 of the transition section 14.

[0047] The thickness direction of the transition section 14 is the same as that of the main body 11, and the width direction of the transition section 14 is the same as that of the main body 11. That is to say, the transition section 14 is directly opposite to the main body 11 in the width direction of the rib 1, and the transition section 14 does not deflect relative to the main body 11. By providing the transition section 14 between the first diversion section 12 and the second diversion section 13, the part of the rib 1 located between the first diversion section 12 and the second diversion section 13 can be prevented from being distorted, thereby effectively increasing the structural strength of the rib 1 and reducing the processing difficulty of the rib 1.

[0048] The transition section 14 is opposite to the rotating shaft of the fan in the axial direction of the rotating shaft of the fan. The area where the transition section 14 is located (the second area 32 of the air outlet grille 100) belongs to the air flow intersection area, and the horizontal component of the air flow velocity (the vertical component of the velocity) is generally parallel to the main body 11. By making the transition section 14 not deflect relative to the main body 11, the horizontal component of the air flow velocity (the vertical component of the velocity) can be made generally parallel to the transition section 14, so as to effectively reduce the impact force of the air flow on the transition section 14, and further effectively reduce the aerodynamic loss and noise.

[0049] Optionally, the transition section 14 is connected to both the first diversion section 12 and the second diversion section 13, so as to further improve the structural strength of the rib 1 and reduce the processing difficulty of the rib 1.

[0050] The rib 1 has a first side and a second side opposite to each other in its thickness direction, that is, the first side of the rib 1 and the second side of the rib 1 are opposite to each other in the thickness direction of the rib 1. The first diversion section 12 deflects relative to the main body 11 towards the first side, and the second diversion section 13 deflects relative to the main body 11 towards the second side. The deflection axes of both the first diversion section 12 and the second diversion section 13 are parallel to the length direction of the rib 1.

[0051] The length direction, width direction, and thickness direction of the main body 11 (transition section 14) are respectively the same as the length direction, width direction, and thickness direction of the rib 1. The length direction of the first diversion section 12 (second diversion section 13) is the same as the length direction of the rib 1.

[0052] The length direction of the rib 1 is as shown by the arrow C in Figure 1 and Figure 6 , the thickness direction of the rib 1 is as shown by the arrow D in Figure 1 and Figure 6 . The width direction of the rib 1 is as shown by the arrow E in Figure 3 and Figure 8 . The up-down direction is as shown by the arrow F in Figure 1 and Figure 6 , the left-right direction is as shown by the arrow G in Figure 1 and Figure 6 , and the front-back direction is as shown by the arrow H in Figure 3 and Figure 8as shown by arrow J in

[0053] As Figures 1-5 shown, a plurality of ribs 1 are arranged at intervals in the horizontal direction, the length direction of the rib 1 is consistent with the vertical direction, and the thickness direction of the rib 1 is consistent with the horizontal direction. For example, the width direction of the rib 1 is consistent with the front-back direction, and the thickness direction of the rib 1 is consistent with the left-right direction.

[0054] The main body 11 is arranged vertically, the transition section 14 is arranged vertically, the thickness direction of the main body 11 and the transition section 14 is consistent with the horizontal direction (such as the left-right direction), and the width direction of the main body 11 and the transition section 14 is consistent with the front-back direction. The first diversion section 12, the transition section 14 and the second diversion section 13 are arranged in the vertical direction.

[0055] For example, the first diversion section 12 is located above the transition section 14, and the second diversion section 13 is located below the transition section 14. The transition section 14 faces the rotating shaft of the fan in the front-back direction (the width direction of the rib 1), the first diversion section 12 is located above the rotating shaft of the fan, and the second diversion section 13 is located below the rotating shaft of the fan.

[0056] When the fan rotates clockwise (viewed from front to back), a part of the air flow blown out by the fan flows through the first diversion section 12 from the left rear to the right front, and another part of the air flow blown out by the fan flows through the second diversion section 13 from the right rear to the left front.

[0057] As Figures 2-5 shown, correspondingly, the first diversion section 12 deflects relative to the main body 11 around the vertical direction (the length direction of the rib 1) towards the left side (the first side) of the rib 1, so that the air inlet side 121 (the rear side) of the first diversion section 12 is located on the left side of the air outlet side 122 (the front side) of the first diversion section 12. The second diversion section 13 deflects relative to the main body 11 around the vertical direction (the length direction of the rib 1) towards the right side (the second side) of the rib 1, so that the air inlet side 131 (the rear side) of the second diversion section 13 is located on the right side of the air outlet side 132 (the front side) of the second diversion section 13. Thus, the deflection directions (deflection angle directions) of the first diversion section 12 and the second diversion section 13 can correspond to the rotation direction of the fan.

[0058] When the fan rotates counterclockwise (viewed from front to back), a part of the air flow blown by the fan flows from the right rear to the left front through the first diversion section 12, and another part of the air flow blown by the fan flows from the left rear to the right front through the second diversion section 13. Correspondingly, the first diversion section 12 deflects relative to the main body 11 around the vertical direction (the length direction of the rib 1) towards the right side (the first side) of the rib 1, so that the air inlet side 121 of the first diversion section 12 is located on the right side of the air outlet side 122 of the first diversion section 12. The second diversion section 13 deflects relative to the main body 11 around the vertical direction (the length direction of the rib 1) towards the left side (the second side) of the rib 1, so that the air inlet side 131 of the second diversion section 13 is located on the left side of the air outlet side 132 of the second diversion section 13. Thus, the deflection directions (deflection angle directions) of the first diversion section 12 and the second diversion section 13 can correspond to the rotation direction of the fan.

[0059] By deflecting the first diversion section 12 relative to the main body 11 around the vertical direction towards the left side (or the right side) of the rib 1, the first diversion section 12 can be made to be generally parallel to the horizontal component of the velocity of the air flow blowing towards the first diversion section 12, or the air inlet side 121 of the first diversion section 12 can be made to be generally tangent to the horizontal component of the velocity of the air flow blowing towards the first diversion section 12, so that the first diversion section 12 can better divert the air flow, effectively reducing the impact force of the air flow on the first diversion section 12, thereby effectively reducing the aerodynamic loss and noise, significantly increasing the air output, and significantly reducing the motor power of the fan.

[0060] Similarly, the second diversion section 13 is generally parallel to the horizontal component of the velocity of the air flow blowing towards the second diversion section 13, or the air inlet side 131 of the second diversion section 13 is generally tangent to the horizontal component of the velocity of the air flow blowing towards the second diversion section 13, so that the second diversion section 13 can better divert the air flow, effectively reducing the impact force of the air flow on the second diversion section 13, thereby effectively reducing the aerodynamic loss and noise, significantly increasing the air output, and significantly reducing the motor power of the fan.

[0061] As Figure 1 and Figure 2 shown, a plurality of reinforcing ribs 2 are provided between adjacent two ribs 1, and the plurality of reinforcing ribs 2 are arranged at intervals in the vertical direction to improve the structural strength of the air outlet grille 100.

[0062] As Figures 6-10 shown, the plurality of ribs 1 are arranged at intervals in the up and down direction, the length direction of the rib 1 is consistent with the horizontal direction, and the thickness direction of the rib 1 is consistent with the up and down direction. For example, the width direction of the rib 1 is consistent with the front and back direction, and the length direction of the rib 1 is consistent with the left and right direction.

[0063] The main body 11 is arranged horizontally, and the transition section 14 is arranged horizontally. The thickness direction of the main body 11 and the transition section 14 is consistent with the up-down direction, and the width direction of the main body 11 and the transition section 14 is consistent with the front-back direction. The first diversion section 12, the transition section 14, and the second diversion section 13 are arranged in the horizontal direction.

[0064] For example, the first diversion section 12 is located on the left side of the transition section 14, and the second diversion section 13 is located on the right side of the transition section 14. The transition section 14 faces the rotating shaft of the fan in the front-back direction (the width direction of the rib 1). The first diversion section 12 is located on the left side of the rotating shaft of the fan, and the second diversion section 13 is located on the right side of the rotating shaft of the fan.

[0065] When the fan rotates clockwise (viewed from the front to the back), a part of the air flow blown by the fan flows from the lower rear to the upper front through the first diversion section 12, and another part of the air flow blown by the fan flows from the upper rear to the lower front through the second diversion section 13.

[0066] As Figures 7-10 shown, correspondingly, the first diversion section 12 deflects relative to the main body 11 around the horizontal direction (the length direction of the rib 1) towards the lower side (the first side) of the rib 1, so that the air inlet side 121 (the rear side) of the first diversion section 12 is located below the air outlet side 122 (the front side) of the first diversion section 12. The second diversion section 13 deflects relative to the main body 11 around the horizontal direction (the length direction of the rib 1) towards the upper side (the second side) of the rib 1, so that the air inlet side 131 (the rear side) of the second diversion section 13 is located above the air outlet side 132 (the front side) of the second diversion section 13. Thus, the deflection directions (deflection angle directions) of the first diversion section 12 and the second diversion section 13 can correspond to the rotation direction of the fan.

[0067] When the fan rotates counterclockwise (viewed from the front to the back), a part of the air flow blown by the fan flows from the upper rear to the lower front through the first diversion section 12, and another part of the air flow blown by the fan flows from the lower rear to the upper front through the second diversion section 13. Correspondingly, the first diversion section 12 deflects relative to the main body 11 around the horizontal direction (the length direction of the rib 1) towards the upper side (the first side) of the rib 1, so that the air inlet side 121 of the first diversion section 12 is located above the air outlet side 122 of the first diversion section 12. The second diversion section 13 deflects relative to the main body 11 around the horizontal direction (the length direction of the rib 1) towards the lower side (the second side) of the rib 1, so that the air inlet side 131 of the second diversion section 13 is located below the air outlet side 132 of the second diversion section 13. Thus, the deflection directions (deflection angle directions) of the first diversion section 12 and the second diversion section 13 can correspond to the rotation direction of the fan.

[0068] By deflecting the first air guiding section 12 relative to the main body 11 around the horizontal direction towards the lower side (or upper side) of the rib 1, the first air guiding section 12 can be made substantially parallel to the vertical component of the velocity of the air flow blowing towards the first air guiding section 12, or the air inlet side 121 of the first air guiding section 12 can be made substantially tangent to the vertical component of the velocity of the air flow blowing towards the first air guiding section 12, so that the first air guiding section 12 can better guide the air flow, effectively reducing the impact force of the air flow on the first air guiding section 12, thereby effectively reducing the aerodynamic loss and noise, significantly increasing the air output, and significantly reducing the motor power of the fan.

[0069] Similarly, the second air guiding section 13 is substantially parallel to the vertical component of the velocity of the air flow blowing towards the second air guiding section 13, or the air inlet side 131 of the second air guiding section 13 is substantially tangent to the vertical component of the velocity of the air flow blowing towards the second air guiding section 13, so that the second air guiding section 13 can better guide the air flow, effectively reducing the impact force of the air flow on the second air guiding section 13, thereby effectively reducing the aerodynamic loss and noise, significantly increasing the air output, and significantly reducing the motor power of the fan.

[0070] As Figure 6 and Figure 7 shown, a plurality of reinforcing ribs 2 are provided between two adjacent ribs 1, and the plurality of reinforcing ribs 2 are arranged at intervals in the horizontal direction to improve the structural strength of the air outlet grille 100.

[0071] As Figures 2-5 and Figures 7-10 shown, the main body 11 includes a first section 113, a second section 114, and a third section 115 arranged in sequence along the length direction of the rib 1. The first air guiding section 12 is connected to the first section 113, the transition section 14 is connected to the second section 114, and the second air guiding section 13 is connected to the third section 115. Specifically, the first air guiding section 12 is connected to the air inlet side (rear side) of the first section 113, the transition section 14 is connected to the air inlet side (rear side) of the second section 114, and the second air guiding section 13 is connected to the air inlet side (rear side) of the third section 115.

[0072] Optionally, the surfaces of the first section 113 and the second section 114 on the second side are flush, and the surfaces of the second section 114 and the third section 115 on the first side are flush. This can make the structure of the rib 1 and the air outlet grille 100 more reasonable and the appearance more beautiful. As Figure 2 shown, the right side surface 1131 of the first section 113 is flush with the right side surface 1141 of the second section 114, and the left side surface 1142 of the second section 114 is flush with the left side surface 1151 of the third section 115. As Figure 7 shown, the upper side surface 1132 of the first section 113 is flush with the upper side surface 1143 of the second section 114, and the lower side surface 1144 of the second section 114 is flush with the lower side surface 1152 of the third section 115.

[0073] Optionally, the surfaces of the transition section 14 and the second section 114 on the second side are flush, and the surfaces of the transition section 14 and the second section 114 on the first side are flush. This can make the structure of the rib 1 more reasonable. As Figure 9 shown, the upper side surface 141 of the transition section 14 is flush with the upper side surface 1143 of the second section 114, and the lower side surface 142 of the transition section 14 is flush with the lower side surface 1144 of the second section 114.

[0074] As Figure 1 , Figure 2 , Figure 6 and Figure 7 shown, the air outlet grille 100 includes a first region 31, a second region 32, and a third region 33. The first diversion sections 12 of the plurality of ribs 1 are located in the first region 31, the transition sections 14 of the plurality of ribs 1 are located in the second region 32, and the second diversion sections 13 of the plurality of ribs 1 are located in the third region 33. The area of the first region 31 is equal to the area of the third region 33, and the area of the first region 31 is greater than the area of the second region 32, that is, the area of the third region 33 is greater than the area of the second region 32.

[0075] Thus, the first diversion section 12 located in the first region 31 and the second diversion section 13 located in the third region 33 can more fully divert the airflows flowing through the first region 31 and the third region 33 respectively, thereby further preventing the airflows from hitting the main body 11, further reducing the aerodynamic loss and noise, and further increasing the air volume flowing through the air outlet grille 100.

[0076] Correspondingly, the first sections 113 of the plurality of ribs 1 are located in the first region 31, the second sections 114 of the plurality of ribs 1 are located in the second region 32, and the third sections 115 of the plurality of ribs 1 are located in the third region 33.

[0077] In Figure 1 and Figure 2 , the horizontal velocity components of the airflows blowing towards the first region 31 and the third region 33 have a certain deflection angle, and the deflection angle direction is the same as the rotation direction of the fan (fan blade). Therefore, the deflection directions of the first diversion section 12 and the second diversion section 13 correspond (match) to the rotation direction of the fan (fan blade). The second region 32 belongs to the airflow intersection area, and the horizontal velocity component of the airflow blowing towards the second region 32 has no deflection angle. Therefore, the transition section 14 does not deflect relative to the main body 11.

[0078] In Figure 6 and Figure 7Among them, the vertical component of the air flow velocity blowing towards the first region 31 and the third region 33 has a certain deflection angle, and the deflection direction is the same as the rotation direction of the fan (blades). Therefore, the deflection directions of the first diversion section 12 and the second diversion section 13 correspond (fit) to the rotation direction of the fan (blades). The second region 32 belongs to the air flow convergence region, and the vertical component of the air flow velocity blowing towards the second region 32 has no deflection angle. Therefore, the transition section 14 does not deflect relative to the main body 11.

[0079] As Figures 8-10 shown, the first diversion section 12 is an arc-shaped section, the second diversion section 13 is an arc-shaped section, and the dimensions of the first diversion section 12, the second diversion section 13, and the transition section 14 in the thickness direction of the rib 1 are equal to each other. This can enable the rib 1 and the air outlet grille 100 to have higher structural strength.

[0080] Optionally, the first diversion section 12 is an arc-shaped section, and the second diversion section 13 is an arc-shaped section. The dimension of the first section 113 in the thickness direction of the rib 1 is H, and the dimension of the third section 115 in the thickness direction of the rib 1 is H. The spacing between two adjacent first sections 113 in the thickness direction of the rib 1 is N, and the spacing between two adjacent third sections 115 in the thickness direction of the rib 1 is N. For example, the thickness of the first section 113 is equal to the thickness of the third section 115. (N - H) is less than or equal to 12 mm.

[0081] This can prevent the fingers of users and staff from reaching into the air conditioner through the gap between two adjacent ribs 1, thereby preventing the fingers from being scratched by the fan, so as to effectively improve the safety of the air outlet grille 100 and the air conditioner and successfully pass the test finger test. Since the dimension of the second section 114 in the thickness direction of the rib 1 is greater than the dimension of the first section 113 in the thickness direction of the rib 1, the difference between the spacing between two adjacent second sections 114 in the thickness direction of the rib 1 and the dimension of the second section 114 in the thickness direction of the rib 1 is also less than 12 mm.

[0082] As Figures 3-5 shown, the first diversion section 12 is a straight section, and the second diversion section 13 is a straight section. The thickness of each of the first diversion section 12, the transition section 14, and the second diversion section 13 gradually increases along the direction from the air inlet side of the rib 1 to the middle part 15 of the rib 1, and the thickness of the main body 11 gradually decreases along the direction from the middle part 15 of the rib 1 to the air outlet side of the rib 1.

[0083] In this way, the widths (areas) of the flow channels between two adjacent first flow guiding sections 12, between two adjacent transition sections 14, and between two adjacent second flow guiding sections 13 can be gradually reduced along the direction from the air inlet side of the rib 1 to the middle part 15, so as to increase the flow velocity of the air flow, reduce the air pressure, and further reduce the reverse pressure gradient resistance of the air flow, making the air outlet smoother, so as to further increase the air volume flowing through the air outlet grille 100.

[0084] Moreover, the width (area) of the flow channel between two adjacent bodies 11 can be gradually increased along the direction from the middle part 15 to the air outlet side of the rib 1, so as to reduce the flow velocity of the air flow, reduce turbulence, and further reduce noise.

[0085] Specifically, the air inlet sides 121 of the first flow guiding sections 12, the air inlet sides 143 of the transition sections 14, and the air inlet sides 131 of the second flow guiding sections 13 constitute the air inlet side of the rib 1. The air outlet sides 112 of the bodies 11 constitute the air outlet side of the rib 1. The connection parts of the first flow guiding sections 12, the transition sections 14, and the second flow guiding sections 13 with the bodies 11 constitute the middle part 15 of the rib 1.

[0086] The dimension of the rib 1 in its width direction is W, and the dimension of the body 11 in the width direction of the rib 1 is W1, where 0.4 ≤ W1 / W ≤ 0.6. This can not only make the body 11 have sufficient width to prevent the air flow from having a deflection angle when flowing out of the air outlet grille 100, but also make the first flow guiding section 12 and the second flow guiding section 13 have sufficient width to further improve the flow guiding effect of the first flow guiding section 12 and the second flow guiding section 13, and further prevent the air flow from hitting the body 11, further reducing the aerodynamic loss and noise.

[0087] When the outdoor unit of the air conditioner is installed in a groove position or there are louvers blocking the outdoor unit of the air conditioner, there is no obstacle directly in front of the air outlet grille 100, and there are often obstacles above, below, and on the sides of the air outlet grille 100. By preventing the air flow from having a deflection angle when flowing out of the air outlet grille 100, the air flow flowing out of the air outlet grille 100 can flow straight ahead (i.e., horizontally forward), preventing the air flow from hitting the obstacles, and further preventing the air flow from accumulating, so as to reduce the air outlet resistance and improve the heat exchange effect.

[0088] That is to say, when W1 / W < 0.4, it will cause the width of the body 11 to be too small, and then cause the air flow to have a deflection angle when flowing out of the air outlet grille 100. When W1 / W > 0.6, it will cause the widths of the first flow guiding section 12 and the second flow guiding section 13 to be too small, resulting in a weak flow guiding effect of the first flow guiding section 12 and the second flow guiding section 13, and then causing the air flow to hit the body 11, increasing the aerodynamic loss and noise.

[0089] Optionally, 0.45 ≤ W1 / W ≤ 0.55. This can not only make the body 11 have sufficient width to prevent the air flow from having an angular deviation when flowing out of the air outlet grille 100, but also make the first diversion section 12 and the second diversion section 13 have sufficient width to further improve the diversion effect of the first diversion section 12 and the second diversion section 13, thereby preventing the air flow from hitting the body 11 and further reducing the aerodynamic loss and noise.

[0090] Further optionally, 0.51 ≤ W1 / W ≤ 0.54. This can not only make the body 11 have sufficient width to prevent the air flow from having an angular deviation when flowing out of the air outlet grille 100, but also make the first diversion section 12 and the second diversion section 13 have sufficient width to further improve the diversion effect of the first diversion section 12 and the second diversion section 13, thereby preventing the air flow from hitting the body 11 and further reducing the aerodynamic loss and noise.

[0091] As Figures 2-5 shown, the first diversion section 12 is a straight section, and the second diversion section 13 is a straight section. The width of the first diversion section 12 is W2, and 1 ≤ W2 / W1 ≤ 1.5. This can not only make the body 11 have sufficient width to prevent the air flow from having an angular deviation when flowing out of the air outlet grille 100, but also make the first diversion section 12 have sufficient width to further improve the diversion effect of the first diversion section 12, thereby preventing the air flow from hitting the body 11 and further reducing the aerodynamic loss and noise.

[0092] That is to say, when W2 / W1 < 1, it will cause the width of the first diversion section 12 to be too small, resulting in a weak diversion effect of the first diversion section 12, and then causing the air flow to hit the body 11, increasing the aerodynamic loss and noise. When W2 / W1 > 1.5, it will cause the width of the body 11 to be too small, and then cause the air flow to have an angular deviation when flowing out of the air outlet grille 100.

[0093] Optionally, the width of the second diversion section 13 is W3, and 1 ≤ W3 / W1 ≤ 1.5. This can not only make the body 11 have sufficient width to prevent the air flow from having an angular deviation when flowing out of the air outlet grille 100, but also make the second diversion section 13 have sufficient width to further improve the diversion effect of the second diversion section 13, thereby preventing the air flow from hitting the body 11 and further reducing the aerodynamic loss and noise.

[0094] That is to say, when W3 / W1 < 1, it will cause the width of the second diversion section 13 to be too small, resulting in a weak diversion effect of the second diversion section 13, and then causing the air flow to hit the body 11, increasing the aerodynamic loss and noise. When W3 / W1 > 1.5, it will cause the width of the body 11 to be too small, and then cause the air flow to have an angular deviation when flowing out of the air outlet grille 100.

[0095] Further optionally, 1.15 ≤ W2 / W1 ≤ 1.35, 1.15 ≤ W3 / W1 ≤ 1.35. This can not only make the body 11 have sufficient width to prevent the airflow from having an angular deviation when flowing out of the air outlet grille 100, but also make the first diversion section 12 and the second diversion section 13 have sufficient width to further improve the diversion effect of the first diversion section 12 and the second diversion section 13, thereby preventing the airflow from hitting the body 11 and further reducing the aerodynamic loss and noise.

[0096] Further optionally, 1.21 ≤ W2 / W1 ≤ 1.24, 1.21 ≤ W3 / W1 ≤ 1.24. This can not only make the body 11 have sufficient width to prevent the airflow from having an angular deviation when flowing out of the air outlet grille 100, but also make the first diversion section 12 and the second diversion section 13 have sufficient width to further improve the diversion effect of the first diversion section 12 and the second diversion section 13, thereby preventing the airflow from hitting the body 11 and further reducing the aerodynamic loss and noise.

[0097] As Figures 2-5 shown, the first diversion section 12 is a straight section, and the included angle α1 between the first diversion section 12 and the body 11 is greater than or equal to 12 degrees and less than or equal to 30 degrees. This not only makes the first diversion section 12 have a large angular deviation to further improve the diversion effect of the first diversion section 12, thereby preventing the airflow from hitting the body 11 and further reducing the aerodynamic loss and noise, but also can prevent the diversion effect of the first diversion section 12 from being weakened due to too large an angular deviation of the first diversion section 12, increasing the front shielding area of the first diversion section 12, and affecting the appearance of the air outlet grille 100.

[0098] That is to say, when the included angle α1 between the first diversion section 12 and the body 11 is less than 12 degrees, the diversion effect of the first diversion section 12 will be weak due to too small an angular deviation of the first diversion section 12, resulting in the airflow hitting the body 11 and increasing the aerodynamic loss and noise. When the included angle α1 between the first diversion section 12 and the body 11 is greater than 30 degrees, it will not only cause the front shielding area of the first diversion section 12 to be too large and affect the appearance of the air outlet grille 100, but also cause the angular deviation of the first diversion section 12 to exceed the angular deviation of the airflow, weakening the diversion effect of the first diversion section 12.

[0099] As Figures 2-5 shown, the second diversion section 13 is a straight section, and the included angle α2 between the second diversion section 13 and the body 11 is greater than or equal to 12 degrees and less than or equal to 30 degrees. This not only makes the second diversion section 13 have a large angular deviation to further improve the diversion effect of the second diversion section 13, thereby preventing the airflow from hitting the body 11 and further reducing the aerodynamic loss and noise, but also can prevent the diversion effect of the second diversion section 13 from being weakened due to too large an angular deviation of the second diversion section 13, increasing the front shielding area of the second diversion section 13, and affecting the appearance of the air outlet grille 100.

[0100] That is, when the included angle α2 between the second flow guiding section 13 and the main body 11 is less than 12 degrees, the flow guiding effect of the second flow guiding section 13 will be weak due to the too small deflection angle of the second flow guiding section 13, and then the airflow will impact the main body 11, increasing the aerodynamic loss and noise. When the included angle α2 between the second flow guiding section 13 and the main body 11 is greater than 30 degrees, it not only causes the front shielding area of the second flow guiding section 13 to be too large, affecting the appearance of the air outlet grille 100, but also causes the deflection angle of the second flow guiding section 13 to exceed the deflection angle of the airflow, weakening the flow guiding function of the second flow guiding section 13.

[0101] Optionally, the included angle α1 between the first flow guiding section 12 and the main body 11 is greater than or equal to 18 degrees and less than or equal to 24 degrees, and the included angle α2 between the second flow guiding section 13 and the main body 11 is greater than or equal to 18 degrees and less than or equal to 24 degrees. This not only further improves the flow guiding effects of the first flow guiding section 12 and the second flow guiding section 13, thereby preventing the airflow from impacting the main body 11, further reducing the aerodynamic loss and noise, but also can prevent the flow guiding functions of the first flow guiding section 12 and the second flow guiding section 13 from being weakened due to the too large deflection angles of the first flow guiding section 12 and the second flow guiding section 13, increasing the front shielding areas of the first flow guiding section 12 and the second flow guiding section 13, and affecting the appearance of the air outlet grille 100.

[0102] Further optionally, the included angle α1 between the first flow guiding section 12 and the main body 11 is greater than or equal to 21 degrees and less than or equal to 24 degrees, and the included angle α2 between the second flow guiding section 13 and the main body 11 is greater than or equal to 21 degrees and less than or equal to 24 degrees. This not only further improves the flow guiding effects of the first flow guiding section 12 and the second flow guiding section 13, thereby preventing the airflow from impacting the main body 11, further reducing the aerodynamic loss and noise, but also can prevent the flow guiding functions of the first flow guiding section 12 and the second flow guiding section 13 from being weakened due to the too large deflection angles of the first flow guiding section 12 and the second flow guiding section 13, increasing the front shielding areas of the first flow guiding section 12 and the second flow guiding section 13, and affecting the appearance of the air outlet grille 100.

[0103] Optionally, the included angle α1 between the first flow guiding section 12 and the main body 11 is equal to the included angle α2 between the second flow guiding section 13 and the main body 11.

[0104] As Figures 7-10 shown, the first flow guiding section 12 is an arc section, and the central angle of the first flow guiding section 12 is greater than or equal to 10 degrees and less than or equal to 60 degrees. That is, the tangent line L1 of the air inlet side edge 125 (such as the rear side edge) of the side surface (such as the upper side surface 123 or the lower side surface 124) of the first flow guiding section 12 in the thickness direction of the rib 1 forms an included angle α3 with the width direction (such as the front-rear direction) of the rib 1, which is greater than or equal to 10 degrees and less than or equal to 60 degrees.

[0105] This not only further improves the flow guiding effect of the first flow guiding section 12, thereby preventing the airflow from hitting the main body 11, further reducing the aerodynamic loss and noise, but also can prevent the airflow flowing through the pressure surface of the air outlet grille 100 from separating due to the excessive angle α3, resulting in an increase in aerodynamic loss and noise.

[0106] That is to say, when the central angle (angle α3) of the first flow guiding section 12 is less than 10 degrees, the flow guiding effect of the first flow guiding section 12 will be weak, thereby causing the airflow to hit the main body 11, increasing the aerodynamic loss and noise. When the central angle (angle α3) of the first flow guiding section 12 is greater than 60 degrees, the airflow flowing through the pressure surface of the air outlet grille 100 will separate, resulting in an increase in aerodynamic loss and noise.

[0107] As Figures 7-10 shown, the second flow guiding section 13 is an arc section, and the central angle of the second flow guiding section 13 is greater than or equal to 10 degrees and less than or equal to 60 degrees. That is to say, the tangent L2 of the air inlet side edge 135 (such as the rear side edge) of the side surface (such as the upper side surface 133 or the lower side surface 134) of the second flow guiding section 13 in the thickness direction of the rib 1 forms an angle α4 with the width direction (such as the front-rear direction) of the rib 1 that is greater than or equal to 10 degrees and less than or equal to 60 degrees.

[0108] This not only further improves the flow guiding effect of the second flow guiding section 13, thereby preventing the airflow from hitting the main body 11, further reducing the aerodynamic loss and noise, but also can prevent the airflow flowing through the pressure surface of the air outlet grille 100 from separating due to the excessive angle α3, resulting in an increase in aerodynamic loss and noise.

[0109] That is to say, when the central angle (angle α4) of the second flow guiding section 13 is less than 10 degrees, the flow guiding effect of the second flow guiding section 13 will be weak, thereby causing the airflow to hit the main body 11, increasing the aerodynamic loss and noise. When the central angle (angle α4) of the second flow guiding section 13 is greater than 60 degrees, the airflow flowing through the pressure surface of the air outlet grille 100 will separate, resulting in an increase in aerodynamic loss and noise.

[0110] Optionally, the central angle (angle α3) of the first flow guiding section 12 is greater than or equal to 25 degrees and less than or equal to 45 degrees, and the central angle (angle α4) of the second flow guiding section 13 is greater than or equal to 25 degrees and less than or equal to 45 degrees. This not only further improves the flow guiding effects of the first flow guiding section 12 and the second flow guiding section 13, thereby preventing the airflow from hitting the main body 11, further reducing the aerodynamic loss and noise, but also can prevent the airflow flowing through the pressure surface of the air outlet grille 100 from separating, thereby preventing an increase in aerodynamic loss and noise.

[0111] Further optionally, the central angle (included angle α3) of the first flow guiding section 12 is greater than or equal to 31 degrees and less than or equal to 34 degrees, and the central angle (included angle α4) of the second flow guiding section 13 is greater than or equal to 31 degrees and less than or equal to 34 degrees. Thereby, not only the flow guiding effects of the first flow guiding section 12 and the second flow guiding section 13 are further improved, and further the airflow is prevented from hitting the main body 11, and the aerodynamic loss and noise are further reduced, but also the separation of the airflow flowing through the pressure surface of the air outlet grille 100 can be prevented, and further the aggravation of the aerodynamic loss and the increase of the noise can be prevented.

[0112] The dimension of the first flow guiding section 12 in the thickness direction of the rib 1 is jointly determined by the thickness of the first flow guiding section 12 and the central angle (included angle α3) of the first flow guiding section 12. The dimension of the second flow guiding section 13 in the thickness direction of the rib 1 is jointly determined by the thickness of the second flow guiding section 13 and the central angle (included angle α4) of the second flow guiding section 13. Optionally, the central angle (included angle α3) of the first flow guiding section 12 is equal to the central angle (included angle α4) of the second flow guiding section 13.
