Abstract

The invention discloses a rotary compressor comprising a seal housing. The seal housing comprises an electrodynamic motor formed by a motor stator with a motor winding, and a motor rotor arranged on the inner diameter of the motor stator; a rotary-type compression device which is arranged on the lower end of the motor and is driven by the motor; a rotor fan arranged on the upper end part of the motor rotor; and an exhaust pipe opening a hole to an oil separation chamber formed between the seal housing and the upper side of the motor. By running of the motor rotor, a fluid in the oil separation chamber passes through the rotor fan, and then flows to the inner circumference of the motor winding. According to the rotary compressor of the embodiment of the invention, by arrangement of the rotor fan, the oil discharge amount from the compressor to a refrigeration circulation system is reduced. Therefore, not only the reliability of the compressor is enhanced, also the efficiency reduction of a heat exchanger can be prevented. In addition, by arrangement of refrigerant cycle of the rotor fan, the motor winding temperature is decreased, so that faults caused by motor efficiency reduction and burning loss can be prevented.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a rotary compressor. Background technique [0002] The characteristic of the rotary compressor is that, in principle, oil is required in the compression chamber to prevent gas leakage, so the refrigerant discharged from the compression chamber is mixed with a large amount of oil. Therefore, there arises a problem that the amount of oil discharged from the exhaust pipe to the refrigerating cycle increases, and the amount of oil in the compressor casing decreases. Various methods have been tried in the past for its improvement, but the effect is not good. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, an object of the present invention is to provide a rotary compressor capable of reducing the amount of oil discharged. [0004] A rotary compressor according to an embodiment of the pre...
