Abstract

The invention relates to a whirl eliminating structure, a mixed-flow fan assembly and an air conditioner. The whirl eliminating structure comprises a whirl eliminating wheel cover (20) with a throughinner cavity, a whirl eliminating hub (30) located in the inner cavity of the whirl eliminating wheel cover (20), and a whirl eliminating blade (40), wherein a whirl eliminating runner (50) is formedbetween the whirl eliminating hub (30) and the whirl eliminating wheel cover (20); the whirl eliminating blade (40) is connected between the wall of the inner cavity and the outer wall of the whirl eliminating hub (30); and the whirl eliminating runner (50) is provided with an inflection point (M3) adjacent to an outlet (52) of the whirl eliminating runner (50) and a radial pole value point (M2) located between an inlet (51) and the inflection point (M3) of the whirl eliminating runner (50) on a center track line (53) from the inlet (51) to the outlet (52) on the longitudinal section of the axis (Z) of a whirl eliminating structure. The air supply performance can be improved.

Description

technical field [0001] The present disclosure relates to the field of fans, in particular to a racemic structure, a mixed-flow fan assembly and an air conditioner. Background technique [0002] The air duct system is one of the components used in the air conditioner to accelerate the heat exchange of the air in the air conditioner's operating area. In the air circuit system of the air conditioner, the designer selects and matches the appropriate fan according to the actual needs corresponding to the different models and specifications of the air conditioner to meet the working quality and comfort of the air conditioner. [0003] In order to meet the air volume and pressure head indicators of the air conditioner, the air path system of some air conditioners known to the inventor uses a mixed flow fan. Contents of the invention [0004] After research, it is found that some mixed-flow fans in air conditioners known to the inventor have the problem of inclined air outlet and...
