Scroll compressor

Abstract

The invention provides a scroll compressor. The scroll compressor comprises a movable scroll plate and a static scroll plate; the movable scroll plate comprises an inner side molded line, an outer side molded line and a tooth head molded line; the static scroll plate comprises an inner side molded line, an outer side molded line and a tooth head molded line; the movable scroll plate inner side molded line comprises a first arc section and a first involute section; the static scroll plate outer side molded line comprises a fourth arc section and a fourth involute section; the first arc sectionis located on the side, away from the first tooth head molded line, of a first inner disengagement point, and the fourth arc section is located on the side, away from the second tooth head molded line, of a second outer disengagement point; and / or the movable scroll plate outer side molded line comprises a second arc section and a second involute section; the static scroll plate inner side moldedline comprises a third arc section and a third involute section; and the second arc section is located on the side, away from the first tooth head molded line, of the first outer disengagement point,and the third arc section is located on the side, away from the second tooth head molded line, of the second inner disengagement point. According to the scroll compressor provided by the invention, rapid exhaust can be achieved, exhaust overcompression is reduced, and the efficiency of the compressor is improved.

Description

technical field [0001] The present application relates to the technical field of compressors, in particular to a scroll compressor. Background technique [0002] The scroll compressor has the advantages of simple structure, small size, light weight, low noise, high mechanical efficiency and stable operation. A scroll compressor is a fluid machine that achieves gas compression by means of volume changes. The dynamic and static scrolls are the main parts of the pump body. The most commonly used profiles of the dynamic and static scrolls are circular involutes and their correction curves. The phase angle difference between the movable scroll and the fixed scroll is 180 degrees. The movable scroll moves under the drive of the crankshaft and meshes with the fixed scroll to form a series of crescent-shaped airtight chambers that are isolated from each other and whose volume changes continuously. When the compression chamber After the refrigerant inside is compressed to the positi...

The phase angle difference between the movable scroll and the fixed scroll is 180 degrees. The movable scroll moves under the drive of the crankshaft and meshes with the fixed scroll to form a series of crescent-shaped airtight chambers that are isolated from each other and whose volume changes continuously. When the compression chamber After the refrigerant inside is compressed to the position of the disengagement point of the profile line, the compression chamber communicates with the discharge port of the fixed scroll and starts to exhaust. Because it still needs to rotate at a certain angle from the disengagement of the scroll profile line to the large opening exhaust, this There will be over-compression problems in the process, which will increase the compression power consumption
