[0050] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0051] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0052] In the description of this application, "first feature" and "second feature" may include one or more of the features. In the description of this application, "multiple" means two or more. In the description of this application, "above" or "below" the second feature may include direct contact between the first and second features, or contact between the first and second features through another feature between them. In the description of this application, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0053] In existing technology, the bracket for mounting the motor in an outdoor air conditioning unit is generally housed separately within the casing and connected to the chassis, top cover, and other structures. This places the motor between the impeller and the heat exchanger. An air guide ring is located on the inner side of the casing's panel, and airflow exits from the panel's outlet under the impeller's drive. Because the bracket, as a separate component, is located between the impeller and the heat exchanger, it obstructs airflow, reducing flow velocity and heat exchange efficiency.

[0054] To address the technical problems existing in the prior art, a solution for integrally molding the support and panel is disclosed in the related technology to reduce the flow loss of air between the impeller and the heat exchanger and improve the heat exchange effect.

[0055] However, molding the support and panel as a single unit essentially relocates the support between the rotor and the mesh cover on the panel. The airflow that performs work on the rotor must first pass through the support and then through the mesh cover before exiting. As a result, compared to existing solutions, the distance between the rotor blade tips and the support is reduced. This causes the airflow to collide with the support, generating stronger turbulent vortex shedding, thus increasing noise.

[0056] Furthermore, since the bracket and panel are integrally molded, it is unavoidable that grooves will form on the bracket and / or panel facing the impeller. This will cause some airflow to flow between the grooves and not be able to be delivered outwards. In addition, a separate air guide ring needs to be set. When the air guide ring is assembled with the bracket and panel, a seamless connection cannot be achieved. Therefore, the high-speed rotating impeller will also fill the assembly gaps with gas, thereby generating abnormal low-frequency noise.

[0057] Therefore, this application proposes a panel assembly for an outdoor air conditioning unit. By setting an air guide component on the inner side of the bracket, the first air guide component can cover the inner side of the bracket near the inner peripheral wall of the air guide ring, thereby controlling the boundary layer on the surface of the bracket at the blade tip of the impeller, reducing the wake region of the wind field, reducing pressure resistance, reducing vortex shedding, and thus reducing noise.

[0058] The panel assembly 10 of an air conditioner outdoor unit according to an embodiment of the present application is described below with reference to Figures 1-10.

[0059] As shown in Figures 1-4, the panel assembly 10 of the outdoor unit of the air conditioner according to the embodiment of this application includes a panel 11 and a bracket 12. The panel 11 is provided with an air outlet 1c, the bracket 12 is provided at the air outlet 1c, and the bracket 12 is connected to the panel 11. The bracket 12 is used to install the motor of the fan assembly 30.

[0060] The panel assembly 10 also includes an air guide component 13, which can be disposed on the inner side of the panel 11. It should be noted that the inner side of the panel 11 here refers to the side of the panel 11 facing the fan wheel 32 when the panel assembly 10 is applied to the outdoor unit of the air conditioner. Conversely, the outer side of the panel 11 refers to the side of the panel 11 facing the external space of the outdoor unit of the air conditioner.

[0061] Specifically, the air guiding component 13 includes an air guiding ring 131 and a first air guiding element 132. The first air guiding element 132 is connected to the inner peripheral wall of the air guiding ring 131. The air guiding ring 131 is disposed opposite to the air outlet 1c and located inside the panel 11. The first air guiding element 132 is disposed inside the bracket 12 and covers the part of the bracket 12 near the inner peripheral wall of the air guiding ring 131, that is, the first air guiding element 132 covers the junction of the air guiding ring 131 and the bracket 12.

[0062] According to the embodiments of this application, the panel assembly 10 of the outdoor unit of the air conditioner can achieve the air guiding effect by setting the air guide component 13 and using the air guide ring 131, thereby reducing the problem of airflow backflow and allowing more air to be discharged from the air outlet 1c. The first air guide component 132 can cover the assembly gap between the air guide ring 131 and the bracket 12, reducing the airflow entering the assembly gap, thereby reducing noise (e.g., low-frequency noise).

[0063] As shown in Figure 2, according to some embodiments of this application, the first air guide 132 has a plurality of spaced recesses 1320 on the side away from the bracket 12.

[0064] The wall surface of the recess 1320 can form a concave spherical surface; multiple recesses 1320 can be evenly arranged on the side surface of the first air guide 132 away from the bracket 12.

[0065] Therefore, by providing a recess 1320 on the side surface of the first air guide 132 away from the support 12, the boundary layer on the surface of the support 12 at the blade tip of the impeller 32 can be controlled, the wake region of the wind field can be reduced, the pressure drag can be reduced, thereby reducing the resistance to airflow at this position, reducing vortex shedding, and further reducing noise.

[0066] When the wall of the recess 1320 is formed as a concave spherical surface, the center of the sphere containing the concave spherical surface can be located on the side surface of the first air guide 132 away from the support 12 or on the extension surface of that surface.

[0067] In some embodiments, the diameter d0 of the sphere containing the concave sphere can be 2mm-3mm. For example, the diameter d0 of the sphere containing the concave sphere can be 2mm, 2.5mm, 3mm, etc. By limiting the size of the concave sphere, the airflow resistance at this location can be further reduced.

[0068] In some embodiments, the minimum distance M1 between the edges of two adjacent concave spherical surfaces is 0.5-1 mm, for example, M1 can be 0.5 mm, 0.7 mm, 0.9 mm, or 1 mm. In still other embodiments, the distance M2 between the centers of the spheres containing two adjacent concave spherical surfaces is 2.5-3 mm, for example, M2 can be 2.5 mm, 2.7 mm, 2.9 mm, or 3 mm. This configuration can further reduce the airflow resistance of the first air guide 132.

[0069] As shown in Figure 1, according to some embodiments of this application, the bracket 12 includes a mounting part 121 and a plurality of support legs 122. The mounting part 121 is used to mount a motor. The plurality of support legs 122 are arranged circumferentially at intervals in the mounting part 121. One end of each support leg 122 in the length direction is connected to the mounting part 121, and the other end of each support leg 122 in the length direction is connected to the panel 11.

[0070] In the above technical solution, by setting the bracket 12 to include the mounting part 121 and multiple support feet 122, the weight of the bracket 12 can be reduced, which is conducive to achieving lightweight design. On the other hand, the installation reliability and stability of the bracket 12 can be guaranteed, thereby ensuring the installation reliability and stability of the fan assembly 30. Furthermore, an air passage is formed between two adjacent support feet 122, allowing the air at the air outlet 1c to flow out normally.

[0071] As shown in Figures 1 and 4, there are multiple first air guides 132, and each of the multiple first air guides 132 covers the portion of the multiple support feet 122 near the inner peripheral wall of the air guide ring 131.

[0072] In other words, each support foot 122 is provided with a first air guide 132 near the inner peripheral wall of the air guide ring 131. Thus, multiple first air guides 132 can cover the assembly gap between the air guide ring 131 and each support foot 122, thereby significantly reducing noise.

[0073] As shown in Figure 3, in some embodiments, the support foot 122 has flanges 1221 extending toward the inside of the support foot 122 on both sides in the width direction. This arrangement can improve the structural strength and deformation resistance of the support foot 122, thereby improving the installation reliability and stability of the motor.

[0074] Furthermore, the first air guide 132 includes a first top air guide plate 1321, which is connected to the inner peripheral wall of the air guide ring 131. The first top air guide plate 1321 covers the space between the two flanges 1221 of the support foot 122 and one end of the two flanges 1221.

[0075] Because the support foot 122 has flanges 1221 on both sides in the width direction, the inner side of the support foot 122 forms a groove. This causes some airflow to flow between the grooves and cannot be sent out. In addition, there will be an assembly gap between the air guide ring 131 and the support foot 122 (especially at the location of the flanges 1221). The impeller 32 will fill the assembly gap with gas, thereby generating abnormal low-frequency noise.

[0076] In the above technical solution, by using the first top air guide plate 1321 to cover the space of the two flanges 1221 of the support foot 122 near the air guide ring 131 and one end of the two flanges 1221 (the end away from the body of the support foot 122), not only can the part of the groove near the air guide ring 131 be covered, but also the assembly gap between the air guide ring 131 and the support foot 122 can be covered, thereby reducing the airflow entering the groove, that is, reducing the scouring effect, improving the airflow pattern, and reducing noise.

[0077] In some examples, the surface of the first top air guide plate 1321 facing away from the support foot 122 is a convex arc surface. By setting the surface of the first top air guide plate 1321 facing away from the support foot 122 as a convex arc surface, the airflow pattern of the support foot 122 near the inner peripheral wall of the air guide ring 131 can be improved from a square column flow to a cylindrical flow, thereby improving the airflow pattern and reducing noise.

[0078] In some examples, the two sides of the support foot 122 in the width direction are connected to the panel 11 by an arc transition. This increases the width of the part where the support foot 122 connects to the panel 11, thereby further improving the structural strength of the bracket 12. The two sides of the first top air guide plate 1321 in the width direction are arc-shaped so that the shape of the first top air guide plate 1321 matches the shape of the inner peripheral wall of the support foot 122 near the air guide ring 131. This can fully cover the inner side of the support foot 122 near the inner peripheral wall of the air guide ring 131, reducing noise generation.

[0079] As shown in Figure 3, in some examples, the first air guide 132 also includes two side air guide plates 1322, which are connected to both sides of the first top air guide plate 1321 in the width direction, and the two side air guide plates 1322 are respectively located on the side of the two flanges 1221 away from each other.

[0080] In other words, the first air guide 132 can cover the inner side of the support foot 122, or it can cover both sides of the support foot 122 in the width direction. This can prevent airflow from entering the assembly gap between the first air guide 132 and the support foot 122, reduce vortex shedding, and thus reduce noise.

[0081] It is understandable that in the above technical solution, connecting multiple first air guides 132 only to the inner peripheral wall of the air guide ring 131 can simplify the structure of the air guide component 13 and simplify the production process.

[0082] As shown in Figures 1-3 and 5-6, in some embodiments, the air guiding component 13 further includes a plurality of second air guiding elements 133, which are correspondingly disposed on the inner side of the plurality of support legs 122, and each second air guiding element 133 extends along the length direction of the support leg 122. By providing a plurality of second air guiding elements 133, the wind-catching effect of the support leg 122 can be reduced, thereby reducing noise.

[0083] In some examples, the support foot 122 has flanges 1221 extending inward toward the side of the support foot 122 on both sides in the width direction. This arrangement can improve the structural strength and deformation resistance of the support foot 122, thereby improving the installation reliability and stability of the motor. The second air guide 133 includes a second top air guide plate 1331, which covers one end of the two flanges 1221 of the support foot 122.

[0084] Because the support foot 122 has flanges 1221 on both sides in the width direction, a groove is formed on the inner side of the support foot 122, which causes some airflow to flow between the grooves and cannot be sent out.

[0085] In the above technical solution, by using the second top air guide plate 1331 to cover one end of the two flanges 1221 of the support foot 122 (the end away from the body of the support foot 122), the groove can be covered, reducing the airflow entering the groove, that is, reducing the scouring effect, improving the airflow pattern, and reducing noise.

[0086] In some specific examples, the surface of the second top air guide plate 1331 facing away from the support foot 122 is a convex arc surface. Thus, by setting the surface of the second top air guide plate 1331 facing away from the support foot 122 as a convex arc surface, the airflow pattern can be improved from the turbulence of a square column to a flow pattern similar to that around a cylinder, thereby reducing noise.

[0087] It should be noted that the height of the convex arc surface of the second top wind guide plate 1331 should be as small as possible. If the height of the convex arc surface is too large, the distance between the convex arc surface and the wind turbine 32 will be too close, which will result in a relatively high vortex shedding noise under high turbulent kinetic energy conditions.

[0088] As shown in Figures 3 and 5, in some specific examples, the second air guide 133 further includes two positioning plates 1332. The two positioning plates 1332 are connected to both sides of the second top air guide plate 1331 in the width direction, and both positioning plates 1332 are inserted into the space between the two flanges 1221 of the support foot 122. That is, a part of the second air guide 133 fills the space between the two flanges 1221 of the support foot 122.

[0089] This design avoids the wind-catching effect in the groove of the support foot 122 and improves the airflow pattern. On the one hand, the positioning plate 1332 can play a supporting role to realize the positioning and installation of the second air guide 133, ensuring the installation reliability and stability of the second air guide 133. On the other hand, it can make the width of the projection of the second air guide 133 in the plane perpendicular to the rotation axis of the motor less than or equal to the width of the projection of the support foot 122 in the same plane, avoiding increasing the air outlet resistance and affecting the power value under the same air volume.

[0090] As shown in Figure 3, in some specific examples, the connection position between the positioning plate 1332 and the second top air guide plate 1331 has a limiting step 1333, which stops at one end of the flange 1221.

[0091] In the above technical solution, the limiting step 1333 can, on the one hand, block the assembly gap between the positioning plate 1332 and the flange 1221 of the support foot 122, preventing the impeller 32 from injecting gas into the assembly gap and generating abnormal low-frequency noise. On the other hand, it can stop the flange 1221 at the end away from the support foot 122 body, realize the positioning and installation of the second air guide 133, thereby further improving the installation reliability and stability of the second air guide 133.

[0092] As shown in Figures 3 and 6, in some embodiments, the first air guide 132 and the second air guide 133 are connected and at least partially overlap in the length direction of the support leg 122, and at least a portion of the flange 1221 is inserted into the gap between the first air guide 132 and the second air guide 133.

[0093] Specifically, in the embodiment where the first air guide 132 includes a side air guide plate 1322, the gap S1 between the flange 1221 and the side air guide plate 1322 can be 0.2mm-0.4mm. For example, the gap S1 between the flange 1221 and the side air guide plate 1322 can be 0.2mm, 0.3mm, 0.4mm, etc.

[0094] In an embodiment where the second air guide 133 includes a positioning plate 1332, the gap S2 between the flange 1221 and the positioning plate 1332 can be 0.2mm-0.4mm. For example, the gap S2 between the flange 1221 and the positioning plate 1332 can be 0.2mm, 0.3mm, 0.4mm, etc.

[0095] In the embodiment where the first air guide 132 includes a side air guide plate 1322 and the second air guide 133 includes a positioning plate 1332, the gap S3 between the side air guide plate 1322 and the positioning plate 1332 located on the same side can be 1mm-1.5mm. For example, the gap S3 between the side air guide plate 1322 and the positioning plate 1332 located on the same side can be 1mm, 1.2mm, 1.5mm, etc., so that the flange 1221 of the support foot 122 can be inserted into the gap between the side air guide plate 1322 and the positioning plate 1332, thereby achieving a full coverage effect.

[0096] The positioning plate 1332 can have a rectangular cross-section, and its thickness S4 can be 1mm-1.5mm, and its length S5 can be 6mm-10mm, etc. For example, the thickness S4 of the positioning plate 1332 can be 1.2mm, and the length S5 can be 8.5mm.

[0097] As shown in Figures 5 and 6, in some embodiments, one end of each second air guide 133 is connected to the first air guide 132, and the other ends of any two adjacent second air guides 133 are connected through a connecting part 1334, so that multiple second air guides 133 can be connected together to ensure the structural strength of the air guide component 13 and improve the reliability of the air guide component 13.

[0098] In some embodiments, the support leg 122 has a structural reinforcement portion 1222 extending along its length direction at the middle of its width direction, further improving the structural strength of the bracket 12. The structural reinforcement portion 1222 can be a reinforcing recess 1320 or a reinforcing protrusion, and is located at the middle of the support leg 122 in the width direction.

[0099] As shown in Figures 7 and 8, according to a further embodiment of this application, the air guide ring 131 includes a first ring body 1311 and a second ring body 1312. The first ring body 1311 is fixed to the panel 11, and the second ring body 1312 is connected to the end of the first ring body 1311 away from the panel 11. The inner peripheral wall of the first ring body 1311 is formed as a cylindrical surface extending in a direction perpendicular to the panel 11, that is, the first ring body 1311 is formed as a straight line, and the inner peripheral wall of the second ring body 1312 is formed as an arc surface that gradually expands in a direction away from the first ring body 1311.

[0100] In the above technical solution, the air guide ring 131 is configured as described above. On the one hand, it can better achieve the air guiding effect, reduce the airflow backflow problem, and allow more air to be discharged from the air outlet 1c. On the other hand, it facilitates the forming of the air guide ring 131 and can also improve the structural strength and deformation resistance of the air guide ring 131.

[0101] As shown in Figure 8, in some examples, the length of the inner peripheral wall of the first ring body 1311 (i.e., the axial length of the first ring body 1311) is L1, the blade height of the impeller 32 of the wind turbine assembly 30 is H, and L1 is 0.18H-0.21H. For example, the length L1 of the inner peripheral wall of the first ring body 1311 can be 0.18H, 0.19H, 0.2H, 0.21H, etc.

[0102] The radius of the circle containing the inner circumference of the second annular body 1312 is R1, and the diameter of the end of the inner circumference of the guide ring 131 closest to the first annular body 1311 is d1, where R1 is 0.048d-0.05d. For example, the radius R1 of the circle containing the inner circumference of the second annular body 1312 can be 0.048d1, 0.049d1, 0.05d1, etc.

[0103] Compared with related technologies, the embodiments of this application reduce the length L1 of the inner peripheral wall of the first ring 1311 and increase the radius R1 of the circle containing the inner peripheral wall of the second ring 1312. This reduces the overall length of the guide ring 131, decreases the structural size of the guide ring 131, lowers the cost, reduces the risk of the guide ring 131 colliding with the impeller 32, and also increases the air intake of the guide ring 131, thus slowing down the flow separation of airflow within the first ring 1311.

[0104] For ease of understanding, a specific embodiment of this application will be used as an example below for comparison with a comparative example.

[0105] In the comparative example, the air guiding component includes an air guiding ring, which includes a first ring body and a second ring body arranged sequentially and connected along its axial direction, with the first ring body disposed close to the panel.

[0106] The structural dimensions of the wind guide ring are quantified by the blade height H of the wind turbine. The length of the first ring of the wind guide ring is 0.3H, and the overall length of the wind guide ring is 0.47H. The diameter of the inner circumference of the second ring near the first ring is D, the diameter of the second ring away from the first ring is 1.05D, the radius of the circle containing the inner circumference of the second ring is 0.034D, and the radius of the circle containing the outer circumference of the second ring is 0.032D.

[0107] In contrast, in a specific embodiment of this application, with the overall duct space dimensions remaining unchanged, the length L1 of the first ring 1311 of the air guide ring 131 of the air guide component 13 is 0.21h, and the overall length L2 of the air guide ring 131 is 0.36h, where h = 0.88H ~ 1H; the diameter of the inner peripheral wall of the second ring 1312 near the position of the first ring 1311 is d, and the diameter of the inner peripheral wall of the second ring 1312 away from the position of the first ring 1311 is 1.09d, where d = 1D ~ 1.0378D; the radius R1 of the circle containing the inner peripheral wall of the second ring 1312 is 0.0486d, and the radius R2 of the circle containing the outer peripheral wall of the second ring 1312 is 0.0426d.

[0108] By comparison, it was found that, compared with the air guide ring 131 of the comparative air guide component 13, the length of the first ring 1311 of the air guide ring 131 in this embodiment is reduced, and the radius of the circle containing the inner peripheral wall of the second ring 1312 is increased.

[0109] Using the same outdoor unit 100 of the air conditioner as the test object, only the air guide component 13 in the above two sets of embodiments was replaced. The test data of the two sets are compared as follows:

[0110] Table 1 Test data of the air guide components in the comparative example

[0111] Table 2 Test data of the air guide component in the embodiments of this application

[0112] As can be seen from Tables 1-2 and Figures 9-10, in this embodiment, because the air guide component 13 is provided on the inward side of the bracket 12, the scouring effect at the groove of the bracket 12 is reduced, and the air volume of the fan assembly 30 is increased at the same speed. When the air volume is 2800, the power can be reduced by 4.3W and the noise can be reduced by 2.4dB, which significantly improves the working efficiency of the fan assembly 30 and also improves the air supply noise.

The motor is disposed on the bracket 12 and is connected to the fan wheel 32 to drive the fan wheel 32 to rotate.

[0115] When the outdoor unit 100 of the air conditioner is working, the outside air of the outdoor unit 100 is driven by the impeller 32 of the fan assembly 30 to form an airflow, and enters the receiving cavity 1a through the air inlet 1b to exchange heat with the heat exchanger 20, and finally is discharged to the outside of the outdoor unit 100 from the air outlet 1c.

[0116] The air conditioner outdoor unit 100 according to the embodiments of this application can reduce noise by adopting the panel assembly 10 of the air conditioner outdoor unit described above.
