Simultaneously, by making the air outlet protrude relative to the base towards the side opposite to the inner cavity of the casing, the risk of the air outlet collapsing is reduced, thereby achieving the purpose of enhancing the structural strength of the air outlet grille and preventing deformation. Furthermore, since the guide ring is located on the outer periphery of the air outlet, the increase in wind resistance due to the guide ring can be reduced, thereby reducing the impact of the air outlet grille on the airflow and ensuring the heat dissipation performance of the outdoor unit.

If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0024] In the description of this utility model, unless otherwise explicitly defined, terms such as setting, installing, connecting, assembling, and cooperating should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0025] Air conditioner outdoor units typically use axial fans to carry the heat from the condenser to the outside through the air outlet and air filter, thus cooling the condenser. The structure of the air filter affects the condenser's heat dissipation efficiency. Generally speaking, adding an air filter will reduce the airflow, but it ensures safety.

[0026] Typically, the air outlet area of ​​an air outlet grille is a perforated structure, making it prone to collapse and deformation. Related technologies use ribs added to the air outlet area to enhance structural strength and prevent deformation. However, directly adding ribs to the outlet area increases air resistance, affecting airflow and significantly reducing its volume. This leads to poorer condenser heat dissipation, ultimately impacting the normal operation and performance of the air conditioner.

[0027] Therefore, referring to Figures 1 to 6 As shown, the first aspect of this utility model provides an outdoor unit, which is a component of an air conditioner. Generally, an air conditioner also includes an indoor unit, and a refrigerant pipe is provided between the outdoor unit and the indoor unit to transfer heat through the refrigerant within the pipe, thereby achieving cooling or heating.

[0028] Reference Figure 1 and Figure 2As shown, the outdoor unit includes a housing 100 and an exhaust grille 200. Typically, the outdoor unit also includes at least a condenser 130 and a fan 140. The housing 100 is assembled from a base, side panels, and a top cover, wherein the lower end of the side panel is connected to the base, the top cover is connected to the upper end of the side panel, and an inner cavity 110 is defined between the base, side panels, and top cover. The condenser 130 and the fan 140 are both installed within the inner cavity 110.

[0029] Reference Figure 2 As shown, the housing 100 is provided with an air outlet 120. Specifically, the side panel includes a front panel, and the air outlet 120 is located on the front panel, meaning the air outlet 120 is located on the front side of the housing 100. The shape of the air outlet 120 can be circular, elliptical, rectangular, or other shapes. The air outlet 120 communicates with the inner cavity 110. The condenser 130 is located behind the air outlet 120, and the fan 140 is located between the condenser 130 and the air outlet 120, with the air inlet of the fan 140 facing the condenser 130 and the air outlet facing the air outlet 120. Therefore, when the air conditioner is running, the fan 140 can drive airflow to quickly carry the heat from the condenser 130 to the outside of the housing 100 through the air outlet 120, thereby cooling the condenser 130.

[0030] Reference Figure 1 , Figure 2 and Figure 5 As shown, the air outlet grille 200 is installed on the outside of the housing 100 and located on the side near the air outlet 120. Specifically, the air outlet grille 200 is installed on the front panel away from the inner cavity 110 and facing the air outlet 120. The air outlet grille 200 and the front panel can be fixedly connected by clips, screws, etc. Typically, the air outlet grille 200 is provided with multiple air outlet holes 2123, which communicate with the air outlet 120. On the one hand, this meets the air cooling requirements; on the other hand, the diameter of the air outlet holes 2123 is usually small, which can prevent users' fingers from entering the inner cavity 110, improve safety, and ensure that the air conditioner complies with safety regulations.

[0031] Reference Figure 2 and Figure 4 As shown, it can be understood that the air outlet mesh cover 200 includes a mesh cover body 210 and a guide ring 220. The mesh cover body 210 is generally plate-shaped. The guide ring 220 is connected to the side of the mesh cover body 210 facing the air outlet 120, that is, the guide ring 220 is connected to the inner side of the mesh cover body 210, and the guide ring 220 is protruding inward relative to the mesh cover body 210.

[0032] Reference Figure 2 and Figure 4As shown, it can be understood that the shape of the guide ring 220 can be circular, elliptical, rectangular, or other shapes. Generally speaking, the shape of the guide ring 220 is basically the same as that of the air outlet 120. The guide ring 220 is arranged around the outer periphery of the air outlet 120. The projections of the edge of the air outlet 120 and the guide ring 220 on the front panel can coincide, or the projection of the edge of the air outlet 120 can be located inside the projection of the guide ring 220. Therefore, the guide ring 220 avoids the air outlet range of the air outlet 120 (i.e., the range surrounded by the edge of the air outlet 120) to reduce the increase in air resistance caused by the guide ring 220.

[0033] Reference Figure 4 and Figure 5 As shown, the mesh cover body 210 includes a base 211 and an air outlet 212. The base 211 is located radially outside the guide ring 220, and the air outlet 212 is located radially inside the guide ring 220. In other words, the structure surrounded by the guide ring 220 on the mesh cover body 210 is the air outlet 212, and the structure on the mesh cover body 210 located outside the guide ring 220 is the base 211. Alternatively, the base 211 can be understood as being connected to the outer periphery of the air outlet 212. Typically, the base 211 is a flat plate structure, and the air outlet 2123 is located on the air outlet 212. The shape of the air outlet 212 is basically the same as the shape of the guide ring 220, and along a direction perpendicular to the mesh cover body 210, the projection of the air outlet 120 falls on the air outlet 212. Therefore, the air inside the inner cavity 110 can be discharged to the outside of the housing 100 through the air outlet 120 and the air outlet hole 2123 of the air outlet section 212 under the drive of the fan, so as to achieve heat dissipation and cool down the condenser 130.

[0034] Because the air outlet 212 is equipped with air outlet holes 2123 to meet heat dissipation requirements, the air outlet 212 is prone to collapse and deformation.

[0035] Therefore, referring to Figure 2 and Figure 3 As shown, it can be understood that the air outlet 212 protrudes from the side opposite to the inner cavity 110 relative to the base 211; that is, the air outlet 212 protrudes outward. Specifically, the air outlet 212 protrudes outward as a whole, and the air outlet 212 bulges outward. Therefore, by making the air outlet 212 protrude, its bending stiffness can be enhanced to a certain extent, thereby reducing the risk of collapse or deformation of the air outlet 212. Reference Figures 2 to 4As shown, it can be understood that by setting a guide ring 220 between the base 211 and the air outlet 212 of the air outlet cover 200, the guide ring 220 can enhance the overall bending stiffness of the air outlet cover 200. Combined with the protruding air outlet 212 to enhance the bending stiffness of the air outlet 212, the overall structural strength of the air outlet cover 200 is enhanced, preventing deformation of the air outlet cover 200. At the same time, since the guide ring 220 is located on the outer periphery of the air outlet 120, it can reduce the increase in wind resistance caused by the guide ring 220, thereby reducing the impact of the air outlet cover 200 on the air volume, that is, reducing the attenuation of the air volume, so as to ensure the heat dissipation performance of the outdoor unit.

[0036] It is understandable that the wall thickness of the guide ring 220 is 2mm to 2.5mm along the radial direction of the guide ring 220, which effectively ensures the structural strength of the air outlet mesh cover 200.

[0037] Reference Figure 2 and Figure 3 As shown, it can be understood that, in a cross-section parallel to the thickness direction of the mesh body 210, the outline of the air outlet 212 on the side opposite to the inner cavity 110 is arc-shaped. Specifically, along the protruding direction of the air outlet 212, the air outlet 212 has a structure that is high in the middle and low around the edges, and the outer endpoints of the air outlet 212 are located on a reference spherical surface. This reduces the space occupied by the air outlet 212, which is beneficial to reducing the overall size of the outdoor unit. At the same time, the air outlet 212, which is protruding outward and has a structure that is high in the middle and low around the edges, has a certain degree of air-gathering effect, causing the air to move towards the central axis of the fan 140 during the air outlet process, which is beneficial to increasing the air outlet distance, thereby carrying heat to a position further away from the casing 100, which is beneficial to improving the heat dissipation effect. The air outlet 212, which has a structure that is high in the middle and low around the edges, is simple to manufacture.

[0038] It is understood that in other embodiments, the outline of the air outlet 212 on the side away from the inner cavity 110 in a cross section parallel to the thickness direction of the mesh body 210 may also be a polygonal shape, a rectangle, etc. The shape of the air outlet 212 is not specifically limited here.

[0039] Reference Figure 3 As shown, it can be understood that the maximum protrusion height of the air outlet 212 relative to the base 211 is defined as H. H can be understood as the maximum distance between the outer side of the air outlet 212 and the outer side of the base 211 in the thickness direction of the mesh body 210. In this embodiment, the protrusion height is greatest at the middle position of the air outlet 212, that is, H is the distance between the middle position of the air outlet 212 and the outer side of the base 211 in the thickness direction of the mesh body 210. Here, the middle position of the air outlet 212 can be understood as the intersection of the outer side of the air outlet 212 and the central axis of the fan 140.

[0040] Reference Figure 3 As shown, it can be understood that the maximum protrusion height H of the air outlet 212 relative to the base 211 satisfies: 10mm ≤ H ≤ 13mm. If H < 10mm, the protrusion height of the air outlet 212 is too small, and the air outlet 212 is prone to collapse or deformation; if H > 13mm, the protrusion height of the air outlet 212 is too large, which on the one hand leads to a larger external unit size, which is not conducive to installation, and on the other hand, the contact area between the air outlet 212 and the air increases, increasing wind resistance. Therefore, 10mm ≤ H ≤ 13mm, for example, H = 10mm, H = 11mm, H = 12mm, H = 12.5mm, or H = 13mm, etc., to enhance the structural strength of the air outlet grille 200, while reducing the increase in wind resistance and the increase in the external unit size.

[0041] Understandably, setting the guide ring 220 on the outer periphery of the air outlet 120 and limiting the protrusion height H of the air outlet 212 to 10mm≤H≤13mm can reduce the increase in wind resistance to a certain extent, but it will still lead to an increase in wind resistance and a decrease in air volume of about 7%.

[0042] Therefore, referring to Figure 2 and Figure 4 As shown, it can be understood that, to further reduce wind resistance, based on the arrangement of the guide ring 220 around the outer periphery of the air outlet 120, the smallest inscribed circle of the guide ring 220 is larger than the largest circumscribed circle of the air outlet 120. That is, the area surrounded by the guide ring 220 is larger than the area surrounded by the edge of the air outlet 120, and on the projection plane of the air outlet mesh 200 in the thickness direction, the projection of the air outlet 120 is located inside the projection of the guide ring 220. This increases the space surrounded by the guide ring 220, that is, increases the area of ​​the air outlet 212, and increases the air outlet area of ​​the air outlet 212, thereby reducing wind resistance and increasing the air volume.

[0043] Reference Figure 2 and Figure 4As shown, it can be understood that the radius of the largest circumscribed circle of the air outlet 120 is defined as R1, and the radius of the smallest circumscribed circle of the guide ring 220 is defined as R2, satisfying: 15mm ≤ R2 - R1 ≤ 30mm. Making R2 - R1 > 15mm increases the air outlet area of ​​the air outlet 212 and reduces the increase in wind resistance caused by the guide ring 220, resulting in an airflow increase of at least 200 m³ / h, approximately 8%, thus reducing the impact on airflow. Making R2 - R1 < 30mm avoids the drawback of a decrease in the structural strength of the air outlet grille 200 due to an excessively large area of ​​the air outlet 212 and an excessively small area of ​​the base 211. Therefore, by ensuring that 15mm≤R2-R1≤30mm, such as R2-R1=15mm, R2-R1=19mm, R2-R1=23mm, R2-R1=26mm, or R2-R1=30mm, the impact on the airflow is reduced while maintaining the structural strength of the air outlet mesh 200, thereby improving the heat dissipation effect.

[0044] Reference Figure 1 , Figure 4 and Figure 6 As shown, the air outlet 212 includes a plurality of first grilles 2121 and a plurality of second grilles 2122, wherein the length of the first grilles 2121 is greater than the length of the second grilles 2122. The plurality of first grilles 2121 are arranged at equal intervals radially along the guide ring 220, and the plurality of second grilles 2122 are respectively connected between two adjacent first grilles 2121, such that a generally rectangular air outlet 2123 is defined between two adjacent first grilles 2121 and two adjacent second grilles 2122. It is readily understood that the air outlet 212 has a plurality of air outlets 2123, which are arranged in a generally rectangular array. The projections of the plurality of first grilles 2121 onto a projection plane perpendicular to the thickness direction of the mesh body 210 are respectively arranged obliquely relative to the height direction of the outdoor unit; for example, the angle between the first grilles 2121 and the height direction of the outdoor unit is 40°, 45°, or 60°, etc. Therefore, when rainwater or other liquids fall on the air outlet 212, the liquid can flow downwards along the first grid 2121, thereby reducing the risk of liquid flowing into the inner cavity 110, effectively protecting electronic components such as the fan 140, ensuring the normal operation of the outdoor unit, and improving reliability.

[0045] It is understandable that, since the first grille 2121 is arranged at an angle relative to the height of the outdoor unit, the first grille 2121 will warp and deform due to stress concentration, causing the entire air outlet cover 200 to warp and deform, affecting assembly and aesthetics.

[0046] Therefore, referring to Figure 4 and Figure 5As shown, it can be understood that multiple ribs 2111 are provided on the side of the base 211 facing the inner cavity 110. These ribs 2111 are arranged at equal intervals along the radial direction of the guide ring 220. The projections of these ribs 2111 onto the projection plane perpendicular to the thickness direction of the cover body 210 are respectively arranged at an inclination relative to the height direction of the outdoor unit, and the inclination of the ribs 2111 is equal to the inclination of the first grille 2121. This equality can be absolute or a small difference. That is, the first grille 2121 is parallel or coincident with the ribs 2111. Similarly, this parallelism can be absolute or approximately parallel. Therefore, by providing the ribs 2111, the stress of the first grille 2121 can be offset, preventing warping and deformation of the air outlet cover 200 due to stress concentration. This helps ensure the flatness of the assembly surface of the air outlet cover 200, facilitating assembly and improving aesthetics. Furthermore, it is easy to understand that by setting the ribs 2111, the bending stiffness of the base 211 can be enhanced, thereby further increasing the structural strength of the air outlet grille 200 and preventing deformation. The height of the ribs 2111 is 3.75mm to 5mm, effectively ensuring the structural strength of the base 211.

[0047] Reference Figure 6 As shown, it can be understood that the air outlet 2123 is configured as a rectangle. It is easy to understand that the first grille 2121 forms the long side of the air outlet 2123, and the second grille 2122 forms the short side of the air outlet 2123. Generally speaking, to ensure sufficient airflow, the long side of the air outlet 2123 is relatively large.

[0048] Reference Figure 6 As shown, it can be understood that the maximum spacing between two adjacent first grille bars 2121 is defined as L1, and the maximum spacing between two adjacent second grille bars 2122 is defined as L2. In this embodiment, L1 < L2. The maximum spacing L1 between two adjacent first grille bars 2121 satisfies: 9.2mm ≤ L1 ≤ 9.8mm. For example, L1 = 9.2mm, L1 = 9.4mm, L1 = 9.5mm, L1 = 9.7mm, or L1 = 9.8mm, etc., to optimize the size of the air outlet 2123. On the one hand, this avoids the disadvantage of a large decrease in air volume due to the size of the air outlet 2123 being too small. On the other hand, it avoids the size of the air outlet 2123 being too large, thereby preventing the user's fingers from entering the inner cavity 110, improving safety, and ensuring that the air conditioner complies with safety regulations.

[0049] Understandably, although the outward protrusion of the air outlet 212 has a certain air-gathering effect, the air-gathering effect is still not ideal and the air outlet distance is insufficient.

[0050] Therefore, referring to Figure 3 , Figure 5 and Figure 6As shown, it can be understood that the guide ring 220 protrudes into the inner cavity 110 relative to the first grille 2121 and the second grille 2122. That is, along the thickness direction of the air outlet grille 200, the height of the guide ring 220 is greater than the height of the first grille 2121 or the second grille 2122. Therefore, the portion of the guide ring 220 that protrudes relative to the first grille 2121 and the second grille 2122 can guide the air towards the central axis of the fan 140, i.e., provide a concentrating effect, thereby enhancing the concentrating effect during the air outlet process, increasing the air outlet distance, and improving the heat dissipation effect.

[0051] Reference Figure 3 and Figure 6 As shown, the air outlet 2123 includes a first section 2124 and a second section 2125. The first section 2124 and the second section 2125 are connected and arranged sequentially along the air outlet 120. That is, the first section 2124 is located at the end of the second section 2125 closest to the inner cavity 110. In a cross-section perpendicular to the thickness direction of the air outlet cover 200, the cross-sectional area of ​​the first section 2124 decreases along the air outlet 120. In other words, the first section 2124 has a converging shape along the air outlet 120. Therefore, the first section 2124 can guide air to its central axis, thereby achieving a concentrating effect, which helps to increase the air outlet distance and carry heat further away from the housing 100, thus improving heat dissipation.

[0052] Reference Figure 6 As shown, it can be understood that along the air outlet direction of vent 120, the ratio of the depth of the first hole segment 2124 to the depth of the second hole segment 2125 is 2 to 4. If the ratio of the depth of the first hole segment 2124 to the depth of the second hole segment 2125 is too small, the air gathering effect of the first hole segment 2124 will be poor, affecting the heat dissipation effect of the outdoor unit. If the ratio of the depth of the first hole segment 2124 to the depth of the second hole segment 2125 is too large, the opening of the first hole segment 2124 near the second hole segment 2125 will be too small, the wind resistance will increase, resulting in a greater decrease in the air volume and affecting the heat dissipation effect of the outdoor unit. Therefore, the ratio of the depth of the first hole segment 2124 to the depth of the second hole segment 2125 is 2 to 4, for example, the ratio of the depth of the first hole segment 2124 to the depth of the second hole segment 2125 is 2, 2.8, 3.2, 3.8 or 4, etc. By reasonably setting the ratio of the depth of the first hole segment 2124 to the depth of the second hole segment 2125, the heat dissipation effect of the outdoor unit can be improved.

[0053] The air conditioner of the second aspect of this utility model includes the outdoor unit of the first aspect of this utility model.

[0055] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
