Problems solved by technology

[0002] It is pointed out in related technologies that the axial flow wind wheel itself has low wind pressure (the total pressure of the fan is low), and the air supply distance is short. The low wind pressure means that the fan has a low ability to overcome the resistance of the surrounding environment. In hot weather, once the axial-flow wind wheel equipped with it cannot effectively overcome the wind resistance around the installation structure, the heat of the heat exchanger in the shell of the outdoor unit cannot be effectively discharged, which will easily cause the air conditioner to trip and stop at high temperature; for split indoor As far as the machine is concerned, low wind pressure (low air supply distance) means that the indoor ambient air cannot be sufficiently disturbed, which will inevitably affect the overall temperature rise and temperature drop rate in the room

Embodiment 1

[0098] refer to Figure 1-Figure 3 , the axial flow wind wheel 100 comprises: a coaxial inner hub 12 and an outer hub 11, three evenly distributed inner blades 3 are arranged between the inner hub 12 and the outer hub 11, and three evenly distributed first blades 3 are arranged on the outer hub 11. Outer blades 21 and six evenly distributed second outer blades 22, wherein the three inner blades 3 correspond to the three first outer blades 21 in the circumferential direction of the outer hub 11, and each corresponding inner blade 3 corresponds to Each first outer blade 21 can constitute a small hub ratio propeller axial flow blade 2000 with a complete aerodynamic configuration, and two second outer blades 22 are arranged between each adjacent two first outer blades 21, each The second outer blades 22 are axial flow blades 3000 with a large hub ratio, and the rotation planes of the inner blades 3 and the outer blades are approximately in the same plane, thereby reducing the desi...

Embodiment 2

[0102] like Figure 4 As shown, the structure of this embodiment is substantially the same as that of Embodiment 1, wherein the same components use the same reference numerals, and the only difference is that the three inner blades 3 and the three first outer blades 21 are located on the circumference of the outer hub 11. Up is not a one-to-one correspondence, but staggered from each other.

[0103] refer to Figure 4 , the connection line between the installation position of each first outer blade 21 on the inner peripheral wall of the outer hub 11 and the center of the outer hub 11, and the closest inner blade 3 (that is, the closest inner blade to the outer hub 11 in the circumferential direction) 3) There is a certain angle α between the installation position on the inner peripheral wall of the outer hub 11 and the line connecting the center of the outer hub 11, so that the periodic pressure pulsation noise ( That is, the waveforms of the rotation noise of the axial flow...

Embodiment 3

[0105] like Figure 5 As shown, the structure of the present embodiment is substantially the same as that of the second embodiment, wherein the same components use the same reference numerals, and the only difference is that the number of inner blades 3 is different.

[0106] refer to Figure 5 , there are five evenly distributed inner blades 3 between the inner hub 12 and the outer hub 11, so that by adjusting the number of inner blades 3, the overall air supply volume of the axial flow rotor 100 can be improved and the axial flow rotor 100 can be reduced. power and noise.

Abstract

The invention discloses an axial flow wind wheel and an air conditioner with the axial flow wind wheel. The axial flow wind wheel comprises an outer wheel hub, an inner wheel hub, a plurality of outer blades and a plurality of inner blades, wherein the inner wheel hub is arranged in the outer wheel hub; the outer blades are arranged on the outer peripheral wall of the outer wheel hub and are arranged in the circumferential direction of the outer wheel hub at intervals; the inner blades are arranged between the inner peripheral wall of the inner wheel hub and the inner peripheral wall of the outer wheel hub and are arranged in the circumferential direction of the inner wheel hub at intervals. According to the axial flow wind wheel, the inner blades and the outer blades are simultaneously arranged on the axial flow wind wheel, so that the overall air-out air trajectory of the axial flow wind wheel can be effectively clipped, the air-out effect of the axial flow wind wheel is effectively improved, and the air sending distance and the air sending power are taken into account by the axial flow wind wheel.

Description

technical field [0001] The invention relates to the field of air conditioning equipment, in particular to an air conditioner with an axial flow wind wheel. Background technique [0002] It is pointed out in related technologies that the axial flow wind wheel itself has low wind pressure (the total pressure of the fan is low) and the air supply distance is short. The low wind pressure means that the fan has a low ability to overcome the resistance of the surrounding environment. In hot weather, once the axial flow wind wheel equipped with it cannot effectively overcome the wind resistance around the installation structure, the heat of the heat exchanger in the outdoor unit casing cannot be effectively discharged, which will easily cause the air conditioner to trip and stop at high temperature; for split indoor As far as the machine is concerned, low wind pressure (low air supply distance) means that the indoor ambient air cannot be sufficiently disturbed, which will inevitabl...
