MULTI-BLADE BLOWER AND AIR CONDITIONING DEVICE

In a multi-blade blower according to the present invention, each blade of an impeller is provided with a first edge and a second edge which are ends in the rotation axis direction of the impeller. Thefirst edge of each blade is connected to a main plate of the impeller. The second edge of each blade faces an intake port. In addition, in the same blade, the distance between the rotation axis and the inner circumferential end gradually increases from a first intermediate section, located between the first edge and the second edge, toward the second edge, and the entrance angle gradually increases from the first intermediate section toward the second edge. In addition, when the outer circumferential end of the blade is observed in a radial direction perpendicular to the rotation axis, the outer circumferential end assumes an approximately straight-line shape that is approximately parallel with the rotation axis. 在本发明的多叶片送风机中，叶轮的各叶片具备第一端和第二端作为所述叶轮的旋转轴方向的端部。各所述叶片的所述第一端与所述叶轮的主板连接。各所述叶片的所述第二端与吸气口相向。另外，在观察同一所述叶片时，所述旋
