[0050] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0051] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
[0052] In the description of the present utility model, "first feature" and "second feature" may include one or more of the features. In the description of the present utility model, "plurality" means two or more. In the description of the present utility model, the first feature "above" or "below" the second feature may include the first and second features being in direct contact, or the first and second features being in contact not directly but through another feature between them. In the description of the present utility model, the first feature "above", "above" and "above" the second feature include the first feature being directly above and obliquely above the second feature, or simply means that the first feature is higher in level than the second feature.
[0053] In the prior art, the bracket for installing the motor of the air conditioner outdoor unit is generally separately arranged in the shell, and connected to the chassis, top cover and other structures, so that the motor is located between the wind wheel and the heat exchanger, and an air guide ring is provided on the inner side of the panel of the shell. Driven by the wind wheel, the air flows out from the air outlet of the panel. Since the bracket is located between the wind wheel and the heat exchanger as a separate component, it will hinder the movement of the air flow, reduce the flow rate and heat exchange efficiency.
[0054] In order to solve the technical problems existing in the prior art, the related art discloses a solution of integrally forming a bracket and a panel, so as to reduce the flow loss of the airflow between the wind wheel and the heat exchanger and improve the heat exchange effect.
[0055] However, forming the bracket and the panel in one piece is equivalent to transferring the position of the bracket to between the wind wheel and the mesh cover on the panel. The airflow that passes through the wind wheel needs to pass through the bracket first and then flow out through the mesh cover. In this way, compared with the existing technical solutions, the distance between the top of the wind wheel blade and the bracket is reduced, and the collision of the airflow with the bracket will produce a vortex shedding phenomenon with strong turbulent kinetic energy, thereby increasing noise.
[0056] Moreover, since the bracket and the panel are integrally formed, it is inevitable that a groove facing the wind wheel is formed on the bracket and / or the panel, which causes part of the airflow to flow between the grooves and cannot be sent out. In addition, a separate air guide ring is required, and when the air guide ring is assembled with the bracket and the panel, it is impossible to achieve a seamless connection. Therefore, the high-speed rotating wind wheel will also inject air into the assembly gap, thereby generating abnormal low-frequency noise.
[0057] To this end, the present application proposes a panel assembly for an air conditioner outdoor unit. By arranging an air guide component on the inner side of the bracket, the first air guide component can cover the portion of the inner wall of the inner side of the bracket close to the air guide ring, thereby controlling the boundary layer of the bracket on the surface of the wind wheel blade top, reducing the wake area of the wind field, reducing the pressure difference resistance, reducing vortex shedding, and thus reducing noise.
[0058] Reference below Figure 1-Figure 10A panel assembly 10 of an air conditioner outdoor unit according to an embodiment of the present invention is described.
[0059] like Figure 1-Figure 4 As shown, the panel assembly 10 of the air-conditioning outdoor unit according to the embodiment of the utility model 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, and the bracket 12 is used to install the motor of the fan assembly 30.
[0060] The panel assembly 10 further 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 wind wheel 32 when the panel assembly 10 is applied to the air conditioner outdoor unit, and conversely, the outer side of the panel 11 refers to the side of the panel 11 facing the external space of the air conditioner outdoor unit.
[0061] Specifically, the air guide component 13 includes an air guide ring 131 and a first air guide member 132. The first air guide member 132 is connected to the inner wall of the air guide ring 131. The air guide ring 131 is arranged opposite to the air outlet 1c and is located on the inner side of the panel 11. The first air guide member 132 is arranged on the inner side of the bracket 12, and the first air guide member 132 covers the part of the inner wall of the bracket 12 close to the air guide ring 131, that is, the first air guide member 132 covers the junction of the air guide ring 131 and the bracket 12.
[0062] According to the panel assembly 10 of the air conditioner outdoor unit of the embodiment of the utility model, by setting the air guide component 13, the air guide ring 131 is used to achieve the air guide effect, reduce the air flow backflow problem, and allow more air to be discharged from the air outlet 1c. The first air guide member 132 is used to cover the assembly gap between the air guide ring 131 and the bracket 12, reduce the air flow entering the assembly gap, and thus reduce noise (such as low-frequency noise).
[0063] like Figure 2 As shown, according to some embodiments of the present invention, a plurality of recesses 1320 arranged at intervals are provided on a side of the first air guide 132 facing away from the bracket 12 .
[0064] The wall surface of the recess 1320 may form a concave spherical surface; a plurality of recesses 1320 may be evenly arranged on the surface of one side of the first air guide 132 facing away from the bracket 12 .
[0065] Therefore, by setting a recess 1320 on the surface of the first air guide 132 facing away from the bracket 12, the boundary layer of the surface of the bracket 12 at the blade top of the wind wheel 32 can be controlled, the wake area of the wind field can be reduced, the pressure difference resistance can be reduced, and the resistance to the airflow at this position can be reduced, reducing vortex shedding, thereby further reducing noise.
[0066] When the wall surface of the recess 1320 is formed as a concave spherical surface, the center of the sphere where the concave spherical surface is located can be located on the side surface of the first air guide 132 facing away from the bracket 12 or on the extended surface of the surface.
[0067] In some embodiments, the diameter d0 of the sphere where the concave spherical surface is located can be 2mm-3mm. For example, the diameter d0 of the sphere where the concave spherical surface is located can be 2mm, 2.5mm, 3mm, etc. By limiting the size of the concave spherical surface, the wind resistance at this position can be further reduced.
[0068] In other 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, 1 mm. In still other embodiments, the distance M2 between the centers of the balls where two adjacent concave spherical surfaces are located is 2.5-3 mm, for example, M2 can be 2.5 mm, 2.7 mm, 2.9 mm, 3 mm, etc. This arrangement can further reduce the wind resistance of the first air guide 132 to the airflow.
[0069] like Figure 1 As shown, according to some embodiments of the utility model, the bracket 12 includes a mounting portion 121 and a plurality of supporting feet 122, the mounting portion 121 is used to mount the motor, the plurality of supporting feet 122 are arranged at intervals in the circumferential direction of the mounting portion 121, one end of each supporting foot 122 in the length direction is connected to the mounting portion 121, and the other end of each supporting foot 122 in the length direction is connected to the panel 11.
[0070] In the above technical solution, by configuring the bracket 12 to include a mounting portion 121 and a plurality of supporting legs 122, on the one hand, the weight of the bracket 12 can be reduced, which is conducive to achieving a lightweight design, and on the other hand, the installation reliability and stability of the bracket 12 can be ensured, thereby ensuring the installation reliability and stability of the fan assembly 30, and an air outlet is formed between two adjacent supporting legs 122, so that the wind at the air outlet 1c can flow out normally.
[0071] Among them, Figure 1 and Figure 4 As shown, there are multiple first air guide members 132 , and the multiple first air guide members 132 cover the inner circumferential wall of the multiple supporting legs 122 close to the air guide ring 131 in a one-to-one correspondence.
[0072] That is to say, each supporting foot 122 is provided with a first air guide member 132 on the inner wall close to the air guide ring 131, so that a plurality of first air guide members 132 can cover the assembly gap between the air guide ring 131 and each supporting foot 122, thereby greatly reducing noise.
[0073] like Figure 3As shown, in some embodiments, both sides of the support foot 122 in the width direction have flanges 1221 extending toward the inner side of the support foot 122. 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 member 132 includes a first top air guide plate 1321 , which is connected to the inner circumferential wall of the air guide ring 131 , and covers the space between the two flanges 1221 of the support foot 122 and one end of the two flanges 1221 .
[0075] Since the supporting foot 122 has flanges 1221 on both sides in the width direction, a groove is formed on the inner side of the supporting foot 122, which will cause part of the airflow to flow between the grooves and cannot be sent out, and there will be an assembly gap between the air guide ring 131 and the supporting foot 122 (especially the position where the flange 1221 is located), and the wind wheel 32 will inject gas into the assembly gap, 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 between the two flanges 1221 of the supporting foot 122 near the air guide ring 131 and one end of the two flanges 1221 (the end away from the supporting foot 122 body), not only the part of the groove close to the air guide ring 131 can be covered, but also the assembly gap between the air guide ring 131 and the supporting foot 122 can be covered, thereby reducing the airflow entering the groove, that is, reducing the wind-driving effect, improving the airflow flow pattern, and reducing noise.
[0077] In some examples, the surface of the first top air guide plate 1321 on one side facing away from the support foot 122 is a convex arc surface. By setting the surface of the first top air guide plate 1321 on one side facing away from the support foot 122 as a convex arc surface, the airflow pattern of the inner peripheral wall of the support foot 122 close to the air guide ring 131 can be improved from square column flow to cylindrical flow, so that the airflow pattern is improved, thereby reducing noise.
[0078] In some examples, both sides of the support foot 122 in the width direction are connected to the panel 11 in an arc transition, so that the width of the portion where the support foot 122 is connected to the panel 11 can be increased, thereby further improving the structural strength of the bracket 12. Both sides of the first top air guide plate 1321 in the width direction are formed into an arc shape, so that the shape of the first top air guide plate 1321 matches the shape of the inner circumferential wall of the support foot 122 close to the air guide ring 131, and the inner side of the support foot 122 close to the inner circumferential wall of the air guide ring 131 can be fully covered to reduce the generation of noise.
[0079] like Figure 3As shown, in some examples, the first air guide member 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] That is to say, the first air guide 132 can cover the inner side of the supporting foot 122, or it can cover both sides of the supporting foot 122 in the width direction. This can prevent the airflow from entering the assembly gap between the first air guide 132 and the supporting foot 122, reduce vortex shedding, and thus reduce noise.
[0081] It can be understood that, in the above technical solution, the plurality of first air guide members 132 are connected only to the inner circumferential wall of the air guide ring 131 , which can simplify the structure of the air guide component 13 and the production process.
[0082] like Figure 1-Figure 3 , Figure 5-Figure 6 As shown, in some embodiments, the wind guide member 13 further includes a plurality of second wind guide members 133, and the plurality of second wind guide members 133 are arranged one by one on the inner side of the plurality of support legs 122, and each second wind guide member 133 extends along the length direction of the support leg 122. By providing a plurality of second wind guide members 133, the wind-driving effect of the support leg 122 can be reduced, thereby reducing noise.
[0083] In some examples, both sides of the support foot 122 in the width direction have flanges 1221 extending toward the inner side of the support foot 122, so that the structural strength and anti-deformation ability of the support foot 122 can be improved, thereby improving the installation reliability and stability of the motor. The second air guide 133 includes a second top air guide plate 1331, and the second top air guide plate 1331 covers one end of the two flanges 1221 of the support foot 122.
[0084] Since both sides of the support foot 122 in the width direction have flanges 1221 , a groove is formed on the inner side of the support foot 122 , which causes part of the airflow to flow between the grooves and cannot be sent out.
[0085] In the above technical solution, by using a second top air guide plate 1331 to cover one end of the two flanges 1221 of the supporting foot 122 (the end away from the supporting foot 122 body), the groove can be covered to reduce the airflow entering the groove, that is, reduce the wind-driving effect, improve the airflow pattern, and reduce noise.
[0086] In some specific examples, the side surface of the second top air guide plate 1331 away from the support foot 122 is a convex arc surface. Therefore, by setting the side surface of the second top air guide plate 1331 away from the support foot 122 as a convex arc surface, the airflow pattern can be improved from a square column spoiler to a cylindrical flow, thereby reducing noise.
[0087] It should be noted that the height of the convex arc surface of the second top wind guide plate 1331 is 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 wheel 32 will be too close, which will cause high vortex shedding noise under high turbulent kinetic energy conditions.
[0088] like Figure 3 and Figure 5 As shown, 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 1331 in the width direction, and the two positioning plates 1332 are inserted into the space between the two flanges 1221 of the support foot 122. In other words, a portion of the second air guide 133 fills the space between the two flanges 1221 of the support foot 122.
[0089] With such a configuration, on the basis of avoiding the wind-shaking effect in the groove of the supporting foot 122 and improving the airflow pattern, on the one hand, the positioning plate 1332 can play a supporting role to realize the positioning installation of the second air guide 133 and ensure the installation reliability and stability of the second air guide 133; on the other hand, the width of the projection of the second air guide 133 in the plane perpendicular to the rotation axis of the motor can be made less than or equal to the width of the projection of the supporting foot 122 in the plane, thereby avoiding increasing the wind resistance and affecting the power value under the same air volume.
[0090] like Figure 3 As shown, in some specific examples, a connection position between the positioning plate 1332 and the second top air guide plate 1331 has a limiting step 1333 , and the limiting step 1333 is stopped 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 supporting foot 122 to prevent the wind wheel 32 from injecting gas into the assembly gap, thereby generating abnormal low-frequency noise; on the other hand, it can be stopped at the end of the flange 1221 away from the supporting foot 122 body to achieve the positioning installation of the second air guide member 133, thereby further improving the installation reliability and stability of the second air guide member 133.
[0092] like Figure 3 and Figure 6As shown, 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 supporting foot 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 an embodiment where the first air guide member 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.

On the other hand, it is convenient for the molding of the air guide ring 131 and can also improve the structural strength and anti-deformation ability of the air guide ring 131.
[0101] like Figure 8 As shown, in some examples, the length of the inner circumferential 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 wind wheel 32 of the wind turbine assembly 30 is H, and L1 is 0.18H-0.21H. For example, the length L1 of the inner circumferential wall of the first ring body 1311 can be 0.18H, 0.19H, 0.2H, 0.21H, etc.

[0103] Compared with the related art, the embodiment of the present application can reduce the overall length of the air guide ring 131, reduce the structural size of the air guide ring 131, reduce costs, reduce the risk of collision between the air guide ring 131 and the wind wheel 32, and increase the air intake of the air guide ring 131, thereby slowing down the flow separation of the airflow in the first ring body 1311.
[0104] For ease of understanding, a specific embodiment of the present application is taken as an example below to compare and illustrate with a comparative example.
[0105] In the comparative example, the air guide component includes an air guide ring, and the air guide ring includes a first ring body and a second ring body which are sequentially arranged and connected along the axial direction thereof, and the first ring body is arranged close to the panel.
[0106] The structural dimensions of the air guide ring are quantified using the blade height H of the wind wheel. The length of the first ring body of the air guide ring is 0.3H, and the overall length of the air guide ring is 0.47H. The diameter of the inner circumferential wall of the second ring body at a position close to the first ring body is D, and the diameter of the second ring body at a position far from the first ring body is 1.05D. The radius of the circle where the inner circumferential wall of the second ring body is located is 0.034D, and the radius of the circle where the outer circumferential wall of the second ring body is located is 0.032D.
[0107] In comparison, in a specific embodiment of the present application, when the size of the entire air duct space remains unchanged, the length L1 of the first ring body 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, wherein h=0.88H~1H; the diameter of the inner circumferential wall of the second ring body 1312 at a position close to the first ring body 1311 is d, and the diameter of the inner circumferential wall of the second ring body 1312 at a position far from the first ring body 1311 is 1.09d, and d=1D~1.0378D; the radius R1 of the circle where the inner circumferential wall of the second ring body 1312 is located is 0.0486d, and the radius R2 of the circle where the outer circumferential wall of the second ring body 1312 is located is 0.0426d.
[0108] By comparison, it is found that, relative to the air guide ring 131 of the air guide component 13 in the comparative example, the length of the first ring body 1311 of the air guide ring 131 in the embodiment of the present application is reduced, and the radius of the circle where the inner wall of the second ring body 1312 is located is increased.
