Scroll compressor

Abstract

A scroll compressor of the present invention comprises: a main housing having a suction port for sucking a refrigerant from the outside; a driving unit provided inside the main housing for generating rotational power; a scroll compression unit comprising a rotational scroll rotated by a rotational power transmitted through the driving unit and having a spiral rotational wrap, and a fixing scroll coupled with the main housing so as to have a fixed location and including a spiral fixing wrap to be engaged with the spiral rotational wrap; and an outlet housing coupled with the main housing and having an inlet port for receiving the high-pressure refrigerant compressed at the scroll compression unit, and an outlet port for discharging the refrigerant received through the inlet port. The outlet housing comprises: an outlet path spirally formed from an inlet and connected to the outlet port formed on an outer circumference of the outside thereof; a connective path formed along the circumferential direction corresponding to the path direction of the outlet path and connected to the outlet path; and a resonance chamber connected to the outlet path through the connective path, and having an expanded volume in comparison with the volume of the connective path so as to reduce noise and pulsation of the refrigerant discharged from the scroll compression unit.

Description

technical field [0001] The present invention relates to a scroll compressor, and more particularly, to a scroll compressor capable of reducing noise and pulsation of discharged fluid. Background technique [0002] In general, a scroll compressor is one that includes scroll teeth and compresses fluid using relative motion between a fixed scroll that is fixed regardless of the rotation of a drive shaft and an orbiting scroll that rotates with the rotation of a drive shaft. equipment. [0003] As one of these scroll compressors, a scroll compressor having a sealing structure for a back pressure chamber disclosed in Korean Patent No. 0912515 includes: a casing, a drive unit for generating torque, a A suction unit that sucks fluid from the outside, a fixed scroll with a helical wrap for compressing the fluid sucked through the suction unit, an orbiting scroll with a helical wrap that meshes with the wrap of the fixed scroll The scroll compression unit and the discharge port thr...

AI Technical Summary

Problems solved by technology

[0004] However, the noise and pulsation due to the fluid are large in the scroll compressor having the above-mentioned characteristics compared with the swash plate compressor, so that the noise causes discomfort and a decrease in performance

[0005] Additionally, in prior art scroll compressors, excessive discharge of fluid can result in reduced efficiency and oil starvation, thus reducing reliability

Therefore, in some cases, a lesser amount of fluid discharge is obtained by using an oil separator with a complicated structure, but it is also economically disadvantageous because of an increase in manufacturing cost
