Abstract

The invention relates to a racemization structure, a mixed flow fan assembly and an air conditioner. The racemization structure comprises a racemization wheel cover (20), a racemization wheel hub (30), and racemization blades (40), wherein a through inner cavity is formed in the racemization wheel cover (20); the racemization wheel hub (30) is located in the inner cavity of the racemization wheelcover (20); the racemization blades (40) are connected between the cavity wall of the inner cavity and the outer wall of the racemization wheel hub (30); the intersection interfaces of the racemization blades (40) and the racemization wheel hub (30) are blade root sections (41); the intersection interfaces of the racemization blades (40) and the racemization wheel cover (20) are blade outer edge sections (42); the projections of contour lines of at least one of the blade root sections (41) and the blade outer edge sections (42) on a longitudinal section passing through an axis of the racemization structure each comprise a drag line; and a first included angle between a tangent of the portion, corresponding to a front edge (43) of the corresponding racemization blade (40), of each drag lineand the axis is greater than a second included angle between the tangent of the portion, corresponding to a tail edge (44) of the corresponding racemization blade (40), of the drag line and the axis.According to the racemization structure, the mixed flow fan assembly and the air conditioner, 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...
