PURPOSE: A structure of cross flow fan of wall mounted type indoor unit is provided to increase blowing capacity discharged through an outlet by increasing intensity of rotating turbulence of fluid generated as the cross flow fan rotates. CONSTITUTION: A blade row(20b) is added on an inside of another blade row(20a) formed on an outside of a cross flow fan(20) so that the cross flow fan has double rows of blades. The blade row added to the inside forms a circular blade row perpendicular to one side of a circle separated from the blade row placed on the outside at fixed interval and has a blade profile identical with the blade row placed on the outside. |
