[0037] Next, refer to Figures 1-7 Describe the air conditioner outdoor unit 100 according to an embodiment of the present utility model.

[0038] Please refer to Figures 1-3 , the air conditioner outdoor unit 100 according to an embodiment of the present utility model includes a housing assembly 10, a heat exchanger 20, and a fan assembly 30.

[0039] The housing assembly 10 has a receiving cavity 101, an air inlet 102, and an air outlet 103. Both the air inlet 102 and the air outlet 103 are in communication with the receiving cavity 101. The housing assembly 10 includes a panel 11, and the air outlet 103 is provided on the panel 11. The heat exchanger 20 is disposed in the receiving cavity 101 and is arranged close to the air inlet 102. The fan assembly 30 is disposed in the receiving cavity 101, and the impeller 32 of the fan assembly 30 is arranged close to the air outlet 103. The impeller 32 is located between the heat exchanger 20 and the motor 31 of the fan assembly 30.

[0040] When the air conditioner outdoor unit 100 operates, the external air of the air conditioner outdoor unit 100 forms an air flow under the drive of the impeller 32 of the fan assembly 30, enters the receiving cavity 101 through the air inlet 102, exchanges heat with the heat exchanger 20, and finally is discharged to the outside of the air conditioner outdoor unit 100 from the air outlet 103.

[0041] Furthermore, the air conditioner outdoor unit 100 further includes a mounting bracket 40. The mounting bracket 40 is provided at the air outlet 103 and is detachably connected to the panel 11. The mounting bracket 40 can be used to mount the motor 31 of the fan assembly 30, and the impeller 32 is connected to the motor shaft of the motor 31, so that the mounting bracket 40, the motor 31, and the impeller 32 can be assembled into an integral body.

[0042] For the air conditioner outdoor unit 100 according to the embodiment of the present invention, by arranging the mounting bracket 40 at the air outlet 103 and detachably connecting it to the panel 11, the number of structural members connected to the mounting bracket 40 is reduced, the installation difficulty of the mounting bracket 40 is lowered, and the mounting bracket 40 and the fan assembly 30 can be disassembled and installed as an integral body, with simple operation, which is also beneficial to improving the installation accuracy of the fan assembly 30, thereby improving the use reliability of the air conditioner outdoor unit 100.

[0043] It should be noted that, in this embodiment, the air inlet 102 can be provided on the back plate 13 of the housing assembly 10 opposite to the panel 11, and the heat exchanger 20 can include a first heat exchange part 21 opposite to the back plate 13; the air inlet 102 can also be provided on the side plate 14 of the housing assembly 10 adjacent to the panel 11, and the heat exchanger 20 can include a second heat exchange part 22 opposite to the side plate 14; of course, the air inlet 102 can be provided on the back plate 13 and the side plate 14 of the housing assembly 10, and the heat exchanger 20 includes a connected first heat exchange part 21 and a second heat exchange part 22, and the first heat exchange part 21 is opposite to the back plate 13, and the second heat exchange part 22 is opposite to the side plate 14.

[0044] Please refer to again Figure 3 and further refer to Figure 4, according to some embodiments of the present utility model, the mounting bracket 40 has a first connection hole 401, and the panel 11 has a second connection hole 110. The mounting bracket 40 is mounted on the panel 11 through fasteners, and the fasteners pass through the first connection hole 401 and the second connection hole 110.

[0045] Specifically, the mounting bracket 40, the motor 31 of the fan assembly 30, and the wind wheel 32 can be first assembled into an integral body, and then the mounting bracket 40 is mounted on the panel 11 through fasteners. When it is necessary to repair or replace other structures such as the motor 31, the fasteners can be removed, so that the mounting bracket 40, the motor 31 of the fan assembly 30, and the wind wheel 32 can be removed as a whole.

[0046] The way that the mounting bracket 40 is mounted on the panel 11 through fasteners makes the mounting and dismounting of the mounting bracket 40 convenient and easy to implement, and can also ensure the mounting reliability of the mounting bracket 40, thereby improving the mounting reliability of the fan assembly 30.

[0047] Please refer to again Figure 2 and Figure 4 , according to some embodiments of the present utility model, the mounting bracket 40 includes a mounting portion 41 and a plurality of support feet 42. The mounting portion 41 is connected to the motor 31, and the plurality of support feet 42 are arranged at intervals in the circumferential direction of the mounting portion 41. The first end in the length direction of each support foot 42 is connected to the mounting portion 41, and the second end in the length direction of each support foot 42 is detachably connected to the panel 11.

[0048] Specifically, the first connection hole 401 can be provided at the second end in the length direction of each support foot 42, and a plurality of second connection holes 110 are correspondingly provided on the panel 11. The plurality of second connection holes 110 are arranged in the circumferential direction of the air outlet 103, so that each support foot 42 is connected to the panel 11 through fasteners.

[0049] In the above technical solution, by setting the mounting bracket 40 to include the mounting portion 41 and the plurality of support feet 42, on the one hand, the weight of the mounting bracket 40 can be reduced, which is beneficial to realizing the lightweight design. On the other hand, the mounting reliability and stability of the mounting bracket 40 can be ensured, thereby ensuring the mounting reliability and stability of the fan assembly 30. And an air passage is formed between two adjacent support feet 42, so that the air at the air outlet 103 can flow out normally.

[0050] Among them, the mounting portion 41 and the plurality of support feet 42 can be integrally formed, that is, the mounting bracket 40 is an integrally formed part. For example, the mounting bracket 40 can be integrally formed by stamping a sheet metal part, which is beneficial to ensuring the structural strength of the mounting bracket 40 and improving the anti-deformation ability of the mounting bracket 40. Further, the number of the support feet 42 of the mounting bracket 40 can be three, four, five or more than five.

[0051] To improve the structural strength and installation reliability of the mounting bracket 40, the width of the second end in the length direction of the support leg 42 is greater than the width of the middle part in the length direction of the support leg 42.

[0052] Please refer to Figure 6 , in some embodiments, multiple support legs 42 are divided into at least two support groups, and the distance between adjacent two support groups is greater than the distance between adjacent two support legs 42 in each support group.

[0053] That is to say, multiple support legs 42 can be centrally arranged in groups. For example, multiple support legs 42 can be divided into two support groups, and multiple support legs 42 in the two support groups can be centrally arranged in the upper region and the lower region above the mounting part 41 respectively; or, multiple support legs 42 in the two support groups can be centrally arranged in the left region and the right region of the mounting part 4141 respectively.

[0054] With such a setting, an air passing opening can be formed between adjacent two support legs 42 in a local area, thereby improving the vortex shedding noise caused by the tip leakage flow of the wind wheel 32.

[0055] Please refer to Figure 7 , in some embodiments, multiple support legs 42 are evenly and spacedly arranged in the circumferential direction of the mounting part 41. That is to say, the distance between adjacent two support legs 42 at the same position is equal.

[0056] In this embodiment, a first connection hole 401 is provided at one end of each of the multiple support legs 42 away from the mounting part 41, and multiple second connection holes 110 are provided on the panel 11. The number of the first connection holes 401 and the number of the second connection holes 110 can be equal, so that the multiple first connection holes 401 and the multiple second connection holes 110 are in one-to-one correspondence in position and are connected in one-to-one correspondence with multiple fasteners.

[0057] Of course, the number of the second connection holes 110 provided on the panel 11 can be greater than the number of the first connection holes 401, so that the installation angle of the mounting bracket 40 on the panel 11 can be adjusted as needed.

[0058] In the above technical solution, by arranging multiple support legs 42 evenly and spacedly in the circumferential direction of the mounting part 41, the structural strength of each region of the mounting bracket 40 can be made more uniform, the stress of the fan assembly 30 acting on the mounting bracket 40 can be more dispersed, the installation reliability and stability of the fan assembly 30 can be improved, and in this way, the rotation speed of the fan assembly 30 can be increased, thereby improving the working efficiency of the fan assembly 30.

[0059] It should be noted that the mounting bracket 40 can also be arranged in other structural forms, and the characteristics exhibited by the mounting brackets 40 of different structural forms can be applied to different models of the fan assembly 30 to meet different requirements.

[0060] In order to improve the structural strength of the mounting bracket 40, in some embodiments, the support leg 42 has a structural strengthening portion 420, and the structural strengthening portion 420 extends along the length direction of the support leg 42. Among them, the structural strengthening portion 420 can be a strengthening recess or a strengthening protrusion, and the structural strengthening portion 420 is located in the middle of the width direction of the support leg 42.

[0061] In other embodiments, flanges 43 are respectively provided on both sides of the support leg 42 in the width direction, and flanges 43 can also be provided on the outer periphery of the mounting portion 41, thereby improving the structural strength of the mounting bracket 40.

[0062] Please refer to again Figure 4 and Figure 5 , in some embodiments, the first end of each support leg 42 includes a connecting portion 421 and a limiting portion 422. The limiting portion 422 is arranged at an angle with the connecting portion 421. The connecting portion 421 is located on the outer periphery of the air outlet 103, and the connecting portion 421 is detachably connected to the outer surface of the panel 11. The limiting portion 422 is arranged inside the air outlet 103 and the limiting portion 422 abuts against the edge of the air outlet 103. Among them, in the embodiment where the first connection hole 401 is provided on the support leg 42, the first connection hole 401 can be provided on the connecting portion 421.

[0063] Thus, by providing the limiting portion 422 and the connecting portion 421, and arranging the limiting portion 422 at an angle with the connecting portion 421, the connecting portion 421 and the limiting portion 422 are in contact with different positions of the panel 11 respectively, and the connecting portion 421 and the limiting portion 422 can abut against the panel 11 from different directions, which can further improve the installation reliability and stability of the mounting bracket 40, thereby ensuring the installation reliability and stability of the fan assembly 30.

[0064] Please refer to again Figure 4 , according to some embodiments of the present invention, the air conditioner outdoor unit 100 further includes an air guide ring 5012, and the air guide ring 5012 is connected to the panel 11 and surrounds the air outlet 103.

[0065] In the above technical solution, by providing the air guide ring 5012, the air guiding effect can be achieved, so that the air flow formed by the fan assembly 30 can be discharged from the air outlet 103 under the guidance of the air guide ring 5012, reducing the occurrence of the air return problem.

[0066] Among them, a part of the wind wheel 32 can extend into the air guide ring 5012. Due to manufacturing errors, it is very difficult for the rotation axis of the wind wheel 32 to coincide with the central axis of the air guide ring 5012, and there may be a certain deviation. There is a gap (tip clearance) between the wind wheel 32 and the air guide ring 5012. If the tip clearance is too large, a large tip leakage vortex will be formed, resulting in increased noise and reduced working efficiency of the fan assembly 30.

[0067] Compared with the technical solution in the related art of connecting the mounting bracket 40 to the heat exchanger 20, the panel 11 and the chassis, in the embodiment of the present application, by connecting the mounting bracket 40 to the panel 11, not only can the installation steps of the mounting bracket 40 be simplified, but also the deviation between the central axis of the mounting bracket 40 and the central axis of the air guide ring 5012 can be reduced. Based on this, the diameter of the wind wheel 32 can be appropriately increased as needed, and the working efficiency of the fan assembly 30 can be improved.

[0068] In addition, since the diameter of the wind wheel 32 is increased, the tip clearance can be reduced, which can not only improve the vortex shedding noise caused by the tip leakage flow, but also prevent the air flow outside the housing assembly 10 from flowing into the accommodation cavity 101 through the tip clearance, thereby hindering the outward discharge of the air flow and avoiding increasing the function of the fan assembly 30, thus affecting the heat exchange performance.

[0069] In some embodiments, the radius of the mounting bracket 40 is R1, and the radius of the air guide ring 5012 is R2, and R1 is 1.025 - 1.075 times that of R2. The radius of the mounting bracket 40 here refers to the maximum vertical distance between the end of the mounting bracket 40 far from its center and its central axis. The radius R1 of the mounting bracket 40 can be 1.025 times, 1.035 times, 1.045 times, 1.055 times, 1.065 times, 1.075 times, etc. of the radius R2 of the air guide ring 5012, whereby the structural reliability of the mounting bracket 40 can be ensured.

[0070] In some embodiments, the gap M (tip clearance) between the wind wheel 32 and the air guide ring 5012 of the fan assembly 30 is 5 mm - 7 mm. For example, the gap M between the wind wheel 32 and the air guide ring 5012 of the fan assembly 30 can be 5 mm, 5.5 mm, 6 mm, 6.5 mm, 7 mm.

[0071] Compared with the technical solution in the related art of connecting the mounting bracket 40 to the heat exchanger 20, the panel 11 and the chassis, in the embodiment of the present application, by connecting the mounting bracket 40 to the panel 11, the deviation between the central axis of the mounting bracket 40 and the central axis of the air guide ring 5012 can be reduced. Based on this, the diameter of the wind wheel 32 can be appropriately increased as needed, so that the tip clearance can be reduced, and thus the vortex shedding noise caused by the tip leakage flow can be improved.

[0072] In some embodiments, the air guide ring 5012 is integrally formed with the panel 11. By integrally forming the air guide ring 5012 with the panel 11, on the one hand, the connection structure between the air guide ring 5012 and the panel 11 can be omitted, ensuring the connection reliability between the air guide ring 5012 and the panel 11, and also simplifying the production process, thereby reducing the production cost. On the other hand, the air guide ring 5012 and the panel 11 are connected together, which can improve the structural strength and anti-deformation ability of each other.

[0073] In some embodiments, the impeller 32 of the fan assembly 30 includes a plurality of blades 321. The projections of the side edges of the plurality of blades 321 on the side away from the rotation axis of the impeller 32 in a plane perpendicular to the rotation axis are on the same circumference, and the center of the circumference is located on the central axis of the air guide ring 5012. That is to say, the radius of the impeller 32 is equal to the radius at the trailing edge of the impeller 32.

[0074] Please refer to again Figure 1 , the housing assembly 10 further includes a protective cover 60. The protective cover 60 is provided on the outer side of the panel 11, and the protective cover 60 is detachably connected to the panel 11. The protective cover 60 has an air outlet area 61, and the air outlet area 61 is disposed opposite to the air outlet 103.

[0075] Specifically, the protective cover 60 is provided with a first mounting hole, and the panel 11 is provided with a second mounting hole. The protective cover 60 and the panel 11 can be detachably connected by a fastener, and the fastener passes through the first mounting hole and the second mounting hole. The air outlet area 61 on the protective cover 60 can be a grille structure, or the air outlet area 61 has a plurality of spaced air outlet holes.

[0076] In the above technical solution, by providing the protective cover 60, on the basis of ensuring the air outlet effect, it can not only protect the internal structure of the housing assembly 10, but also prevent foreign objects, even human hands or small animals from entering the housing assembly 10, reducing potential safety hazards.

[0078] Since the air conditioner outdoor unit according to the embodiment of the present invention has the above technical effects, the air conditioner according to the embodiment of the present invention also has the above technical effects, that is, by adopting the above air conditioner outdoor unit 100, the installation and disassembly difficulty of the air conditioner can be reduced, and the use reliability of the air conditioner can be improved.
