The invention discloses an inclined flow air wheel and an air conditioner with the same. The inclined flow air wheel comprises a hub and multiple blades. The hub is a hollowed rotating body, and an arc outer diameter of an intake end of the hub is D; the multiple blades are arranged on the outer peripheral wall of the hub at intervals; the blades comprise first edges contacted with the outer peripheral wall of the hub, second edges aligned to the first edges, third edges connected between the first edges and the second edges and near an exhaust end of the hub, and fourth edges connected between the first edges and the second edges and near the intake end of the hub; and a plane of intersecting points between the second edges and the fourth edges and two end points of the first edges is supposed as a reference surface, in projections of the blades on the reference surface, the linear sizes of two end points of the first edges, the second edges, the third edges and the fourth edges are respectively L1, L2, L3 and L4, wherein L1 is 1.1 D, L2 is 1.2 D, L3 is 0.8 D, and L4 is 0.6 D. The inclined flow wind wheel is high in air volume and low in noise.
