Abstract:
An impeller of a centrifugal fan includes multiple blades arranged annularly around a rotational axis, a main plate, a shroud, main plate-side welded portions between main plate-side blade axial ends of the blades and the main plate, and shroud-side welded portions between shroud-side blade axial ends of the blades and the shroud. The main plate is arranged opposite to main plate-side blade axial ends. The shroud is arranged opposite to shroud-side blade axial ends. The main plate-side welded portions have main plate-side welding holes that are recesses extending through the main plate to portions of the main plate-side blade axial ends. The shroud-side welded portions have shroud-side welding holes that are recesses extending through the shroud to portions of the shroud-side blade axial ends.

Claim (Index 15):
An apparatus for manufacturing an impeller of a centrifugal fan, the impeller being manufactured by welding between multiple blades arranged annularly around a rotational axis and a main plate and a shroud, the main plate and the shroud being respectively arranged opposite to two blade axial ends that are both ends of each of the blades along a direction of the rotational axis, the apparatus comprising:\n a main plate-side ultrasonic horn directed to each of the blades and the main plate to weld between the main plate and a main plate-side blade axial end that is one of the two blade axial ends of each of the blades, the main plate-side ultrasonic horn including main plate-side insertion portions that are inserted through the main plate to portions of the main plate-side blade axial ends; and a shroud-side ultrasonic horn directed to each of the blades and the shroud to weld between the shroud and a shroud-side blade axial end that is the other of the two blade axial ends of each of the blades, the shroud-side ultrasonic horn including shroud-side insertion portions that are inserted through the shroud to portions of the shroud-side blade axial ends.
