Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] The following description refers to the air outlet grille 100 according to the first aspect of the present invention.

[0037] According to the embodiment of the present utility model, the air outlet grille 100, such as Figure 1 and Figure 2 As shown, the air outlet grille 100 includes: end ribs 1 and first air guide ribs 2. The end ribs 1 extend along a first direction X. There are multiple first air guide ribs 2 extending along the first direction X. The multiple first air guide ribs 2 are spaced apart along a second direction Y. In the second direction Y, the end ribs 1 are located on the outermost side of the multiple first air guide ribs 2. An air outlet channel 3 is defined between the end ribs 1 and the adjacent first air guide ribs 2, and between adjacent first air guide ribs 2. The first direction X and the second direction Y intersect. The surface of the end ribs 1 that participates in defining the air outlet channel 3 includes a first air guide surface 11 and a second air guide surface 13. The second air guide surface 13 is located on the air outlet side of the first air guide surface 11. In the second direction Y, the second air guide surface 13 is located on the side of the first air guide surface 11 away from the first air guide ribs 2.

[0038] The air outlet grille 100 is used for air outlet. An air outlet channel 3 is defined between the end rib 1 and the adjacent first air guide rib 2, and an air outlet channel 3 is also defined between the adjacent first air guide rib 2. Airflow can flow out from the air outlet channel 3.

[0039] The end rib 1 is located on the outermost side of the first air guide rib 2 in the second direction Y. Multiple first air guide ribs 2 are spaced apart along the second direction Y, and both the end rib 1 and the first air guide ribs 2 extend along the first direction X. Thus, the end rib 1 and the first air guide ribs together define the air outlet range extending along the first direction X and the second direction Y. The air outlet channel 3 extends along the first direction X, and multiple air outlet channels 3 are arranged spaced apart along the second direction Y. Multiple air outlet channels 3 allow large airflow to pass through, and the regularly arranged air outlet channels 3 have a good guiding effect on the airflow, which can improve the smoothness of airflow.

[0040] An air outlet channel 3 is also defined between the end rib 1 and the first air guide rib 2 adjacent to the end rib 1. The surface of the end rib 1 includes a first air guide surface 11 and a second air guide surface 13. The second air guide surface 13 is located on the air outlet side of the first air guide surface 11, and the first air guide surface 11 is located on the air inlet side of the second air guide surface 13. When the airflow flows out from the air outlet channel 3, it first flows through the first air guide surface 11 and then flows through the second air guide surface 13.

[0041] In the second direction Y, the second air guide surface 13 is located on the side of the first air guide surface 11 away from the first air guide rib 2, that is, the second air guide surface 13 is set away from the defined air outlet channel 3 relative to the first air guide surface 11. Therefore, the air outlet channel 3 defined by the second air guide surface 13 is constructed as a widened section, the outflow area of ​​the airflow increases suddenly, and the air pressure drops. Therefore, the airflow will be quickly drawn into the section of the air outlet channel 3 defined by the second air guide surface 13 and quickly diffused out. The dashed line with arrows in the figure indicates the direction of airflow.

[0042] The second air guide surface 13, which participates in defining the air outlet channel 3, is constructed with an flared section, which increases the coverage of the airflow in the second direction Y and reduces airflow backflow. The second air guide surface 13 is positioned opposite the first air guide surface 11 and away from the first air guide rib 2, further reducing the contact between the airflow and the second air guide surface 13. When delivering cold airflow, it reduces the occurrence of condensation on the second air guide surface 13, thereby reducing the impact of condensation accumulation on the surrounding environment.

[0043] According to the embodiment of the present utility model, the air outlet grille 100, by setting a second air guide surface 13 that is opposite to the first air guide surface 11 and away from the first air guide rib 2, can reduce airflow backflow and reduce the contact between airflow and the second air guide surface 13, thereby reducing the generation of condensation on the second air guide surface 13.

[0044] In some embodiments of this utility model, such as Figure 2 As shown, the air outlet end of the first air guide surface 11 extends obliquely toward the air outlet channel 3 and away from the second air guide surface 13.

[0045] The air outlet end of the first air guide surface 11 extends closer to the air guide rib 2 relative to the second air guide surface 13. Therefore, the air outlet channel 3 defined by the first air guide surface 11 is formed as a narrow section. The first air guide surface 11 guides the airflow in a direction away from the second air guide surface 13, which can not only further reduce the contact between the airflow and the second air guide surface 13, but also increase the airflow speed. The airflow is accelerated in the air outlet channel 3 defined by the first air guide surface 11, which can blow the airflow passing through the air outlet grille 100 further to obtain a longer air delivery distance and improve the airflow coverage.

[0046] When delivering cold air, it can improve the situation of cold air sinking too quickly and enhance the effect of preventing cold air from blowing directly; by increasing the delivery distance of cold air, it can also reduce the accumulation of cold air on the second direction Y side of the air outlet grille 100 and its impact on nearby structures, thereby reducing the condensation on nearby structures.

[0047] In some embodiments of this utility model, such as Figure 2 As shown, the end rib 1 also includes a third air guide surface 12, which is located between the first air guide surface 11 and the second air guide surface 13. The third air guide surface 12 intersects with the first air guide surface 11, and the third air guide surface 12 intersects with the second air guide surface 13.

[0048] The third air guide surface 12 is located between the first air guide surface 11 and the second air guide surface 13, and the airflow flows through the first air guide surface 11, the third air guide surface 13 and the second air guide surface 13 in sequence.

[0049] The third air guide surface 12 does not continue to extend along the extension direction of the first air guide surface 11; the third air guide surface 12 intersects with the first air guide surface 11. The third air guide surface 12 does not extend in the same direction as the second air guide surface 13; the third air guide surface 12 intersects with the second air guide surface 13.

[0050] Therefore, the third air guide surface 12 connected between the first air guide surface 11 and the second air guide surface 13 can change the shape of the air outlet channel 3 defined by the end rib 1, thereby improving the air outlet effect of the air outlet channel 3.

[0051] For example, the third air guide surface 12 extends obliquely in a direction away from the air outlet channel 3 and away from the first air guide surface 11. The section of the air outlet channel 3 defined by the third air guide surface 12 is formed as a widened section, which can increase the coverage of the airflow in the second direction Y and reduce airflow backflow. The third air guide surface 12 is positioned away from the first air guide rib 2 relative to the first air guide surface 11, which can also reduce the contact between the airflow and the third air guide surface 12. When delivering cold airflow, the occurrence of condensation on the third air guide surface 12 can be reduced, thereby reducing the impact of condensation accumulation on the surrounding environment. Furthermore, since the second air guide surface 12 is connected to the air outlet end of the third air guide surface 12, the contact between the airflow and the second air guide surface 12 can be further reduced.

[0052] Optionally, the third air guide surface 12 has a larger tilt angle relative to the second air guide surface 13 and is further away from the first air guide rib 2. The third air guide surface 12 defines an air outlet channel 3 with a larger flow area, while the flow area of ​​the air outlet channel 3 defined by the second air guide surface 13 continues to increase but tends to be gentler. This can stably guide the airflow and reduce airflow backflow.

[0053] Alternatively, the third air guide surface 12 has a smaller inclination angle relative to the second air guide surface 13 and further away from the first air guide rib 2. The third air guide surface 12 defines an air outlet channel 3 with an increased flow area, and the second air guide surface 13 defines an air outlet channel 3 with an even larger flow area. This can further reduce the contact between the airflow and the second air guide surface 12. When delivering cold airflow, it can reduce the condensation on the second air guide surface 13, thereby reducing the impact of condensation accumulation on the surrounding environment.

[0054] For example, the third air guide surface 12 extends obliquely toward the air outlet channel 3 and away from the first air guide surface 11. The air outlet channel 3 formed by the third air guide surface 12 is a narrowed section, and the third air guide surface 12 extends obliquely relative to the first air guide surface 11, thus further guiding the airflow away from the second air guide surface 13. This not only further reduces the contact between the airflow and the second air guide surface 13, but also further increases the airflow velocity, enabling the airflow passing through the air outlet grille 100 to be blown further, thereby achieving a longer air delivery distance and improving the airflow coverage.

[0055] In some embodiments of this utility model, such as Figure 2 As shown, the third air guide surface 12 extends obliquely in a direction away from the air outlet channel 3 and away from the first air guide surface 11. The section of the air outlet channel 3 defined by the third air guide surface 12 is formed as a widened section, which increases the coverage of the airflow in the second direction Y and reduces airflow backflow. The third air guide surface 12 is positioned away from the first air guide rib 2 relative to the first air guide surface 11, further reducing the contact between the airflow and the third air guide surface 12. When delivering cold airflow, condensation on the third air guide surface 12 is reduced, thereby reducing the impact of condensation accumulation on the surrounding environment. Furthermore, since the second air guide surface 12 is connected to the air outlet end of the third air guide surface 12, the third air guide surface 12 is positioned further away from the first air guide rib 2, further reducing the contact between the airflow and the second air guide surface 12.

[0056] In some embodiments of this utility model, such as Figure 2 As shown, on the longitudinal section of the end rib 1 parallel to the second direction Y, the line connecting the air outlet end of the second air guide surface 13 and the air outlet end of the first air guide surface 11 is the first connecting line 14, and the third air guide surface 12 is located on the side of the first connecting line 14 away from the air outlet channel 3.

[0057] A longitudinal section is drawn along the second direction Y, and a line is drawn between the air outlet end of the second air guide surface 13 and the air outlet end of the first air guide surface 11, which is called the first connecting line 14. It can be understood that if the third air guide surface 12 is not provided, then the first connecting line 14 will participate in defining the air outlet channel 3 on the air outlet side of the first air guide surface 11, and the airflow will directly diffuse out along the flared opening formed by the first air guide surface 11.

[0058] By setting a third air guide surface 12, which is located on the side of the first connecting line 14 away from the air outlet channel 3, and the second air guide surface 13 located on the air outlet side of the third air guide surface 12, which is also located on the side of the first connecting line 14 away from the air outlet channel 3, the third air guide surface 12 is located further away from the air outlet channel 3 than the first connecting line 14. However, the airflow still follows a similar path to the air outlet channel 3 defined by the first air guide surface 11. Therefore, the contact between the airflow and the third air guide surface 12 and the second air guide surface 13 can be reduced, thereby reducing the condensation on the third air guide surface 12 and the second air guide surface 13 and reducing the impact of condensation accumulation on the surrounding environment.

[0059] In some embodiments of this utility model, such as Figure 2 As shown, the angle between the third air guide surface 12 and the first connecting line 14 is α3, where 5° < α3 < 20°.

[0060] When the angle α3 between the third air guide surface 12 and the first connecting line 14 is too large, the space formed by the third air guide surface 12 and the second air guide surface 13 increases, and the airflow is prone to accumulate in the space and generate turbulence, which is not conducive to airflow. When the angle α3 between the third air guide surface 12 and the first connecting line 14 is too small, the airflow is prone to contact with the third air guide surface 12 and the second air guide surface 13, which easily leads to condensation.

[0061] Therefore, it is optimal to limit the included angle α3 between the third air guide surface 12 and the first connecting line 14 to 5° < α3 < 20°. This not only facilitates the smooth flow of air through the third air guide surface 12 and the second air guide surface 13, but also reduces the condensation on the third air guide surface 12 and the second air guide surface 13.

[0062] Optionally, the included angle α3 between the third air guide surface 12 and the first connecting line 14 can be 7°, 10°, 15°, 12°, 18°, etc.

[0063] In some embodiments of this utility model, such as Figure 2 As shown, the angle between the third air guide surface 12 and the reference plane m is α2, where 15° < α2 < 45°, and the reference plane m is perpendicular to the second direction Y and parallel to the first direction X.

[0064] The first direction X is perpendicular to the second direction Y, and the reference plane m is parallel to the first direction X and perpendicular to the second direction Y.

[0065] When the angle α2 between the third air guide surface 12 and the reference plane m is too large, the angle between the third air guide surface 12 and the first air guide surface 11 decreases, and the space of the groove formed by the third air guide surface 12 relative to the first air guide surface 11 increases. This is not only detrimental to the structural stability of the end rib 1, but also makes the space defined by the third air guide surface 12 prone to turbulence, which is not conducive to airflow. Conversely, when the angle α2 between the third air guide surface 12 and the reference plane m is too small, the airflow is more likely to come into contact with the third air guide surface 12, which easily leads to condensation on the third air guide surface 12.

[0066] Therefore, it is optimal to limit the angle α2 between the third air guide surface 12 and the reference plane m to 15° < α2 < 45°. This not only reduces the contact between the airflow and the third air guide surface 12 and reduces the condensation generated on the third air guide surface 12, but also helps to stabilize the airflow.

[0067] Optionally, the angle α2 between the third air guide surface 12 and the reference plane m can be 20°, 25°, 30°, 35°, 40°, etc.

[0068] In some embodiments of this utility model, such as Figure 2 As shown, on the longitudinal section of the end rib 1 parallel to the second direction Y, the distance H between the air outlet end of the third air guide surface 12 and the air outlet end of the end rib 1 is ≥2mm.

[0069] This allows the second air guide surface 13 to have sufficient length, enabling it to guide the airflow and thus improve the air outlet effect.

[0070] In some embodiments of this utility model, such as Figure 2 As shown, the angle between the first air guiding surface 11 and the reference plane m is α1, where 3° < α1 < 15°, and the reference plane m is perpendicular to the second direction Y and parallel to the first direction X.

[0071] Both the end rib 1 and the first air guide rib 2 extend along the first direction X, which is perpendicular to the second direction Y. The reference plane m is parallel to the first direction X and perpendicular to the second direction Y.

[0072] An angle α1 between the first air guide surface 11 and the reference plane m that is too large or too small is not conducive to airflow. When the angle α1 between the first air guide surface 11 and the reference plane m is too large, the area occupied by the first air guide surface 11 inward in the air outlet channel 3 is too large, which increases the resistance to airflow and is not conducive to airflow. Alternatively, the first air guide surface 11 needs to extend a large dimension in the first direction X, occupying a large space. When the angle α1 between the first air guide surface 11 and the reference plane m is too small, the effect of the first air guide surface 11 in increasing the airflow velocity is weak, which is also not conducive to airflow.

[0073] Therefore, it is optimal to limit the angle α1 between the first air guide surface 11 and the reference plane m to 3° < α1 < 15°. This can accelerate the airflow, allow the airflow to achieve a longer delivery distance, improve the airflow coverage, and reduce the airflow resistance, which is beneficial to the airflow flow.

[0074] Optionally, the angle α1 between the first air guide surface 11 and the reference plane m can be 4°, 5°, 7.5°, 10°, 12°, etc.

[0075] In some embodiments of this utility model, such as Figure 3 As shown, the surface of the first air guide rib 2 used to participate in defining the air outlet channel 3 is the fourth air guide surface 21. The fourth air guide surface 21 is formed as an inclined surface that is inclined relative to the reference plane m, wherein the reference plane m is perpendicular to the second direction Y and parallel to the first direction X.

[0076] An air outlet channel 3 is defined between one of the adjacent end ribs 1 in the first air guide rib 2 and the other two adjacent first air guide ribs 2. By setting the fourth air guide surface 21 that defines the air outlet channel 3 as an inclined surface that is inclined relative to the first direction X, the airflow can be guided in the inclined direction X when passing through the air outlet grille 100, thereby increasing the coverage of the airflow or improving the air delivery effect.

[0077] Optionally, an air outlet channel 3 is defined between two adjacent first air guide ribs 2. The fourth air guide surface 21 of the first air guide ribs 2 defining the air outlet channel 3 in the second direction Y can be set as an inclined surface. That is, the two side walls of the air outlet channel 3 in the second direction Y extend at an inclination relative to the reference plane m, so that the airflow is guided at an inclination.

[0078] Alternatively, the first air guide rib 2 may be configured as an inclined surface on the same side of the air outlet channel 3 defined in the second direction Y, that is, one side wall of the air outlet channel 3 in the second direction Y extends in a direction parallel to the reference plane, and the other side wall of the air outlet channel 3 in the second direction Y extends at an inclination relative to the reference plane m, so that the airflow is guided at an inclination.

[0079] For example, such as Figure 3 As shown, the first direction X is the front-to-back direction, the second direction Y is the up-to-down direction, the reference plane m is the horizontal plane, and the fourth air guide surface 21 is set upward relative to the reference plane m along the airflow direction, so as to guide the airflow upward and throw the airflow to a higher place, thereby increasing the coverage of the airflow.

[0080] For example, the first direction X is the front-to-back direction, the second direction Y is the up-to-down direction, the reference plane m is a horizontal plane, and the fourth air guide surface 21 is inclined downward relative to the reference plane m along the airflow direction, thereby pressing the airflow down and reducing the direct airflow.

[0081] In some embodiments of this utility model, such as Figure 3 As shown, the angle between the fourth air guide surface 21 and the reference plane m is α4, where 0° < α4 < 15°.

[0082] When the angle α4 between the fourth guide surface 21 and the reference surface is too large, the fourth guide surface 21 tends to extend along the second direction Y. Although the guiding angle increases, the obstruction of airflow also increases, which will increase airflow resistance. Therefore, setting the angle α4 between the fourth guide surface 21 and the reference surface to 0° < α4 < 15° is optimal. This can guide the airflow and reduce airflow resistance, which is beneficial to airflow.

[0083] Optionally, the angle α4 between the fourth air guide surface 21 and the reference surface can be 2°, 5°, 8°, 10°, 14°, etc.

[0084] In some embodiments of this utility model, such as Figure 3 As shown, the air inlet end of the first air guide rib 2 is provided with a guide surface 22, which is inclined in the direction of the air outlet channel 3.

[0085] The guide surface 22 is tilted toward the air outlet channel 3, which can guide the airflow toward the air outlet channel 3, which is conducive to the airflow flowing into the air outlet channel 3, thereby improving the airflow flow in the air outlet grille 100.

[0086] In some embodiments of this utility model, the guide surface 22 is constructed as an arc-shaped surface, which can reduce wind resistance, provide better guidance for airflow, and facilitate airflow into the air outlet channel 3.

[0087] In some embodiments of this utility model, such as Figure 4 As shown, at least one first air guide rib 2 has a plurality of air guide protrusions 23 spaced apart along the first direction X at its air inlet end.

[0088] The air inlet end of the first air guide rib 2 is provided with multiple air guide protrusions 23 spaced apart along the first direction X. Therefore, the air inlet end of the first air guide rib 2 is wavy in the first direction X. By setting the air guide protrusions 23, the air can be dispersed, which can reduce wind resistance and facilitate the airflow into the air outlet channel 3; and it can also allow the air to diffuse and wrap around the air outlet end of the first air guide rib 2, reducing the generation of condensate.

[0089] In some embodiments of this utility model, such as Figure 2 and Figure 4As shown, in the third direction Z, the length of the end rib 1 is greater than the length of the first air guide rib 2, and the third direction Z is set perpendicular to the first direction X and the second direction Y respectively.

[0090] The airflow direction is similar to the third direction Z. By reducing the size of the first air guide rib 2 in the third direction Z, the contact between the airflow and the first air guide rib 2 can be reduced, thereby reducing the generation of condensation on the first air guide rib 2.

[0091] In some embodiments of this utility model, such as Figure 2 and Figure 4 As shown, the air outlet grille 100 also includes a second air guide rib 4, which intersects with a plurality of first air guide ribs 2.

[0092] The air outlet grille 100 includes intersecting first air guide ribs 2 and second air guide ribs 4, which can improve the structural stability of the air outlet grille 100, reduce the shaking or deformation of the air outlet grille 100, improve the working stability of the air outlet grille 100, and help reduce air outlet noise.

[0093] Furthermore, by setting intersecting first air guide ribs 2 and second air guide ribs 4, users can be prevented from directly putting their hands in, which can improve the situation where users accidentally put their hands in during cleaning or other activities.

[0094] In some embodiments of this utility model, in the third direction Z, the length of the second air guide rib 4 is less than the length of the first air guide rib 2, and the third direction Z is respectively set perpendicular to the first direction X and the second direction Y.

[0095] The airflow direction is similar to the third direction Z. By reducing the size of the second air guide rib 4 in the third direction Z, the contact between the airflow and the second air guide rib 4 can be reduced, thereby reducing the generation of condensation on the second air guide rib 4.

[0096] Furthermore, since the length of the second guide rib 4 is less than the length of the first guide rib 2, the condensation generated on the second guide rib 4 can be received by the first guide rib 2, which can reduce the impact of condensation accumulation and flow down on the surrounding environment.

[0097] In some embodiments of this utility model, such as Figure 1 As shown, the air outlet grille 100 includes a decorative area 100a and an air outlet area 100b. In the second direction Y, the decorative area 100a is located on one side of the air outlet area 100b. The air outlet area 100b is provided with end ribs 1 and a plurality of first air guide ribs 2. The end ribs 1 are ribs of the air outlet area 100b facing the decorative area 100a.

[0098] The air outlet grille 100 includes a decorative area 100a and an air outlet area 100b. The air outlet area 100b defines an air outlet channel 3 and is used to guide the airflow. The air outlet area 100b is provided with end ribs 1 and multiple first air guide ribs 2. The end ribs 1 are positioned close to the decorative area 100a relative to the multiple first air guide ribs 2. The decorative area 100a is a solid structure with higher structural strength and can be used for the assembly and connection of the air outlet grille 100.

[0099] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the decorative area 100a includes a decorative panel 5 and a decorative rib 6, the decorative rib 6 extending along a first direction X and protruding from the decorative panel 5.

[0100] The decorative ribs 6, like the end ribs 1 and the multiple first air guide ribs 2, protrude from the decorative panel 5, which can make the overall unity of the decorative area 100a and the air outlet area 100b stronger and improve the visual separation between the decorative area 100a and the air outlet area 100b.

[0101] The air conditioner 1000 of the second aspect of the present invention is described below with reference to the accompanying drawings.

[0102] According to an embodiment of the present utility model, the air conditioner 1000, such as Figure 5 As shown, the air conditioner 1000 includes: a housing 200, the housing 200 being provided with an air outlet grille 100, the air outlet grille 100 being the air outlet grille 100 according to the first aspect embodiment of the present utility model.

[0103] According to the embodiment of the present utility model, by setting the air outlet grille 100 of the first aspect of the present utility model, the air supply range of the air conditioner 1000 can be increased, thereby improving the air outlet heat exchange effect of the air conditioner 1000, and reducing the condensation at the air outlet of the air conditioner 1000, thus improving the impact of condensation dripping on the surrounding environment during the operation of the air conditioner 1000.

[0104] In some embodiments of this utility model, such as Figure 5 and Figure 6 As shown, the air conditioner 1000 has a first direction X which is the front-to-back direction and a second direction Y which is the up-and-down direction. The end ribs 1 and the first air guide ribs 2 of the air outlet grille 100 are spaced apart in the up-and-down direction. In the airflow direction, the first air guide surface 11 of the end rib 1 is inclined downward relative to the horizontal surface, and the third air guide surface 12 is inclined upward relative to the horizontal surface.

[0105] In some embodiments of this utility model, such as Figure 5 and Figure 6As shown, the housing 200 is provided with a first air outlet 201, and the front surface of the housing 200 is provided with a mounting groove 202; the air outlet grille 100 includes a decorative area 100a and an air outlet area 100b, the air outlet area 100b is provided with end ribs 1 and multiple first air guide ribs 2, the decorative area 100a is located in the mounting groove 202, and the air outlet area 100b is positioned directly opposite the first air outlet 201.

[0106] The decorative area 100a is a solid structure and is used for the installation of the air outlet grille 100. The decorative area 100a is located in the mounting groove 202, which can improve the installation stability of the air outlet grille 100 and improve the overall integrity of the air outlet grille 100 after installation. After the decorative area 100a is installed in the mounting groove 202, the air outlet area 100b is directly opposite the first air outlet 201. The air from the first air outlet 201 is sent out through the air outlet grille 100. The cooperation between the decorative area 100a and the mounting groove 202 can also play a positioning role for the air outlet area 100b, which can improve the working stability of the air outlet area 100b.

[0107] In some embodiments of this utility model, such as Figure 5 and Figure 6 As shown, the decorative area 100a is located above the air outlet area 100b. The airflow from the air outlet area 100b has a longer delivery distance. When delivering cold air, it can reduce the situation where the cold air directly gathers in the decorative area 100a from the air outlet area 100b, thereby reducing the condensation at the decorative area 100a.

[0108] In some embodiments of this utility model, such as Figure 6 As shown, an insulation component 300 is provided between the end rib 1 and the housing 200.

[0109] The end ribs 1 are positioned close to the decorative area 100a relative to the multiple first air guide ribs 2. Therefore, in the air outlet area 100b, the end ribs 1 are closest to the solid structure of the casing 200. By providing a heat insulation component 300 between the end ribs 1 and the casing 200, the impact of airflow-induced temperature changes on the casing 200 caused by the end ribs 1 can be reduced. When the air conditioner 1000 delivers cold air, the temperature of the end ribs 1 drops. By providing the heat insulation component 300, the temperature drop near the air outlet of the casing 200 can be mitigated, thereby reducing the generation of condensation on the casing 200.

[0110] In some embodiments of this utility model, such as Figure 6 As shown, the housing 200 is provided with an air guide assembly 400, which defines an air guide channel 401. The upper wall of the air guide channel 401 is inclined downward and extends inclined towards the air outlet grille 100.

[0111] The upper wall of the air guide channel 401 extends downward at an angle, which can guide the airflow downward at an angle. When the airflow passes through the air outlet grille 100, it flows downward at an angle, thereby reducing the contact between the airflow and the end rib 1 located at the upper end of the first air outlet 201, and reducing the generation of condensation on the end rib 1.

[0112] In some embodiments of this utility model, such as Figure 6 As shown, the housing 200 includes a face frame 7 and a front panel 8. The front panel 8 is located on the front side of the face frame 7, and the air outlet grille 100 is located on the front panel 8. A portion of the face frame 7 is located between the air guide channel 401 and the air outlet grille 100.

[0113] The front panel 8 is located on the front side of the face frame 7. The face frame 7 supports the installation of the front panel 8, and part of the face frame 7 is located between the air guide channel 401 and the air outlet grille 100. The face frame 7 can also transport airflow.

[0114] Optionally, the air vent grille 100 and the front panel 8 are integrated, providing strong overall integrity and structural stability, reducing relative sway and thus minimizing airflow noise. Alternatively, the air vent grille 100 and the front panel 8 can be separate components, formed separately and then snap-fitted together. Separate components facilitate the disassembly of the air vent grille 100, making subsequent cleaning easier or allowing for its individual replacement.

[0115] In some embodiments of this utility model, such as Figure 6 As shown, the portion of the face frame 7 located between the upper wall of the air guide channel 401 and the air outlet grille 100 is provided with a planar guide section 71.

[0116] The upper wall of the air guide duct 401 is inclined downward and extends obliquely toward the air outlet grille 100. The guide section 71 is connected between the upper wall of the air guide duct 401 and the air outlet grille 100. The guide section 71 is constructed as a horizontal plane, so that there is a smooth transition between the upper wall of the air guide duct 401 and the air outlet grille 100.

[0117] The guide section 71 connects the upper wall of the air guide channel 401 and the end rib 1. The upper wall of the air guide channel 401 extends downward at an angle, guiding the airflow downward at an angle. The guide section 71 smoothly transitions between the guide channel and the end rib 1, guiding the airflow to the end rib 1. The end rib 1 is provided with a first air guide surface 11, which extends downward at an angle. The first air guide surface 11 further guides the airflow downward and allows the airflow to achieve a longer delivery distance. The end rib 1 is also provided with a third air guide surface 12, which extends upward at an angle. This reduces the contact between the downward-flowing airflow and the third air guide surface 12, thereby reducing the generation of condensation on the third air guide surface 12.
