A centrifugal impeller and associated air fryer, aimed at addressing the technical issue arising from the defective design of fan blade structure found in existing comparable products. This deficiency results in inadequate uniformity of airflow and temperature field distribution, diminished cooking performance, and reduced baking success rate. The body of the centrifugal impeller is irregular inclined fan blade, irregular inclined fan blade is a cross-flow fan blade; wherein round disc plate on the inner side below annular plate of irregular inclined fan blade is formed by outwardly stamping and protruding. The irregular inclined fan blades of the structure are used in the air fryer featuring rear air heating. These blades are positioned within the back heat shield to facilitate the circulation of air within hot air channel of cavity. The air in cold air channel is circulated through the use of stirring fan blades located behind irregular inclined air blades.
A centrifugal impeller, the body of the centrifugal impeller is an irregular inclined fan blade, an inclined spacer is provided on the circumferential surface between the annular plate and the round disc plate of the said irregular inclined fan blade. Lugs on both sides of the inclined spacer are inserted into the holes of the annular plate and the round disc plate, then bent and fixed as one. The center of the round disc plate is equipped with the through-shaft hole. The said irregular inclined fan blade is a cross-flow fan blade;
