Centrifugal wind wheel and air conditioner

The invention discloses a centrifugal wind wheel and an air conditioner, and relates to the technical field of air conditioners. The centrifugal wind wheel comprises a positioning ring and a plurality of blades. The multiple blades are arranged in the positioning ring in an annular array mode and fixedly connected with the positioning ring, the ends, close to the center point of the positioning ring, of the blades are provided with first end points, the multiple first end points jointly define an inner circle, and the range of the ratio of the diameter of the inner circle to the inner diameter of the positioning ring is 0.7-0.75. Compared with the prior art, the centrifugal wind wheel provided by the invention has the advantages that the inner circle of which the ratio of the diameter to the inner diameter of the positioning ring is 0.7-0.75 is adopted, so that the flowing property of an air flow field can be improved, the flow speed attenuation is reduced, the air outlet speed is increased, the air supply st
