Abstract
An oil suction propeller structure for a hermetically sealed compressor includes a rotor, a crank shaft pressure-inserted in the rotor, an oil guide piece pressure-inserted in a lower portion of the crank shaft, a lower wing fixedly inserted in the oil guide piece and soaked in an oil, an upper wing having a width thereof wider than that of the lower wing, and an intermediate portion extending from the lower wing and gradually broadening in width toward the upper wing. The oil suction propeller structure improves oil supply capacity, and minimizes a whirling sound and a dropping noise which may occur during the rotation of the oil guide piece and the oil suction propeller thereof, for thereby enhancing reliability of the hermetically sealed compressor.
