[0025] In the air conditioner outdoor unit, the wind wheel 200 is located inside the area surrounded by the wind guide ring 100. Along the air outlet direction of the wind guide ring 100, the front end of the wind guide ring 100 is the air outlet end, and the rear end of the wind guide ring 100 is the air inlet end, and the air inlet end is located at the rear side of the blades 210 of the wind wheel 200. This scheme is the same as the technical scheme of the air conditioner outdoor unit in which the rear end of the blades 210' of the wind wheel 200' is located at the rear side of the air inlet end (referred to as the comparative scheme, see Figure 3 , number 100' is an air guide ring, number 200' is a wind wheel, number 210' is a blade), under the same rotation speed of the wind wheel 200, the air volume of the wind beam blown out from the air outlet end of the air guide ring 100 of this scheme is greater than the air volume of the wind beam blown out from the air outlet end of the air guide ring 100' of the comparative scheme; under the same air outlet volume, the noise of the wind beam blown out from the air outlet end of the air guide ring 100 of this scheme is less than the noise of the wind beam blown out from the air outlet end of the air guide ring 100' of the comparative scheme.

[0026] The air inlet end may be coplanar with the rear end of the blade 210 of the wind wheel 200 (not shown in the diagram); or Figure 2 As shown, the air inlet end is located on the rear side of the rear end of the blade 210 of the wind wheel 200, etc.; the above can all achieve the purpose of this application, and its purpose does not deviate from the design concept of the utility model, and will not be repeated here, and should all fall within the protection scope of this application.

In addition, the peripheral wall of the air guide ring 100 also includes a transition connection section 120, which connects the contraction section 110 and the expansion section 130.

[0028] It can be that the busbar of the transition connecting section 120 is parallel to the axis of the air guide ring 100 (not shown in the figure); or it can be that Figure 2As shown, the transition connection section 120 is inclined from back to front toward the radial outer side of the air guide ring 100, etc.; the above can achieve the purpose of this application, and its purpose does not deviate from the design concept of the utility model, and will not be repeated here, and should all fall within the protection scope of this application.

[0029] The air outlet end may be coplanar with the front end of the blade 210 of the wind wheel 200; or the air outlet end may be located on the front side of the front end of the blade 210 of the wind wheel 200 along the air outlet direction of the air guide ring 100, etc. All of the above can achieve the purpose of the present application, and its purpose does not deviate from the design concept of the present utility model, and will not be repeated here, and should all fall within the protection scope of the present application.

[0030] In some embodiments, Figure 2 As shown, the air outlet assembly further includes a driving motor 300 , which is located at the rear side of the wind wheel 200 and connected to the wind wheel 200 , and is used to drive the wind wheel 200 to rotate.

[0031] In some embodiments, Figure 2 As shown, the air conditioner outdoor unit also includes a shell and a heat exchanger. The heat exchanger is arranged in the shell, and the air outlet assembly is located on the front side of the heat exchanger.

[0032] In some embodiments, Figure 2 As shown, in the axial direction of the air guide ring 100, the distance between the rear end of the blade 210 of the wind wheel 200 and the air inlet end is X, the minimum inner diameter (inner diameter is diameter) of the air guide ring 100 is D, the minimum distance between the blade 210 of the wind wheel 200 and the peripheral wall of the air guide ring 100 is S, the maximum distance between the rear end of the blade 210 of the wind wheel 200 and the front end of the blade 210 of the wind wheel 200 is H (wherein, H≥25mm), the curvature radius of the contraction section 110 is Ri, the curvature radius of the expansion section 130 is Ro, 0≤X / D≤10%, 0.2%≤S / D≤1%, 5mm≤Ri≤0.3H, 5mm≤Ro≤0.2H; the transition connection section 120 is inclined from back to front toward the radial outer side of the air guide ring 100, and the angle K between the generatrix of the transition connection section 120 and the axis of the air guide ring 100 is not greater than 5 degrees.

[0033] Compared with the technical solution in which the rear end of the blade 210 of the wind wheel 200 is located at the rear side of the wind inlet end (the minimum inner diameter of the air guide ring 100 of the two solutions is the same, and the wind wheel 200 is exactly the same), Figure 4 As shown in FIG. 1 , at the same speed of the wind wheel 200 (the speed is 900 rpm), the air volume of the wind beam blown out from the air outlet end of the wind guide ring 100' of the comparative solution is 7416 CMH, and the air volume of the wind beam blown out from the air outlet end of the wind guide ring 100 of this solution is 8259 CMH. The air volume of this solution is increased by about 11.4% compared with the air volume of the comparative solution; and, as Figure 4As shown, the comparison scheme will experience stalling when the air volume is around 5000CMH, but this scheme will not experience stalling. Figure 4 In the figure, m is the air volume-total pressure curve of this scheme, n is the air volume-total pressure curve of the comparison scheme, and p is the air volume-total pressure curve of the air conditioner outdoor unit system resistance.

[0034] Compared with the technical solution in which the rear end of the blade 210' of the wind wheel 200' is located on the rear side of the air inlet end of this solution (the minimum inner diameter of the air guide ring of the two solutions is the same, and the wind wheels are exactly the same), under the same air output volume (the air output volume is 7421CMH), the rotation speed of the wind wheel 200 of this solution is 820rpm and the wind output noise is 58.3dB(A), while the rotation speed of the wind wheel 200' of the comparative solution is 900rpm and the wind output noise is 60.8dB(A). The rotation speed of the wind wheel 200 of this solution is less than the rotation speed of the wind wheel 200', and the noise of the wind beam blown out from the air outlet end of the air guide ring 100 of this solution is less than the noise of the wind beam blown out from the air outlet end of the air guide ring 100 of the comparative solution.

[0035] It can be X / D=0; or it can be X / D=5%; or it can be X / D=10%, etc.; it can be S / D=0.2%; or it can be S / D=0.6%; or it can be S / D=1%, etc.; it can be K=2 degrees; or it can be K=3 degrees; or it can be K=5 degrees, etc.; all of the above can achieve the purpose of this application, and its purpose does not deviate from the design concept of the utility model, and will not be repeated here, and should all fall within the protection scope of this application.
