Scroll compressor

Abstract

The present invention provides a scroll compressor, to solve the performance deteriorating problem generated by over pressure loss as the communicating path connected to the discharge outlet is narrower regardless whether or not the coolant gas in the compressing chamber achieves the prescribed pressure. Nearly simultaneously before or after the invention is separated by a first compression chamber (15a), the discharge outlet (18) passes across the vortex disc teeth (13a) of rotary scroll discs (13) to lead to the structure of the first compression chamber, as the discharge outlet (18) forms an opening directly in the first compression chamber (15a), and the communicating path can be thoroughly ensured added with the gap between the vortex disc teeth of the two rotary scroll discs, therefore the over-compression loss can be reduced.

Description

technical field [0001] The invention relates to a scroll compressor used in refrigerating devices such as heating and cooling air conditioners, refrigerators, or heat pump water heaters. Background technique [0002] Generally speaking, in the existing scroll compressors used for refrigeration, air-conditioning or refrigeration equipment, the fixed scroll and the orbiting scroll with spiral scroll teeth erected from the mirror plate are engaged with each other. A compression chamber is formed between them. When the orbiting scroll is rotated along a circular orbit by the rotation limiting structure on the basis of limiting the rotation, the compression chamber moves while changing the volume, and performs operations such as suction, compression, and exhalation. The refrigerant gas is gradually compressed with the rotation of the orbiting scroll, becomes high pressure as it moves toward the center, and is discharged into the inner space of the airtight container when it reac...

Problems solved by technology

[0005] However, in the conventional structure described above, the point corresponding to the curling start angle of the wrap tooth outer wall of the orbiting scroll is in the rotation angle range of 15° to 40° after being separated from the wrap tooth inner wall of the fixed scroll. Inside, the discharge port communicates with the first compression chamber, so there is still the possibility of causing overcompression

Especially in the process of low compression ratio operation with the highest frequency in actual use, this overcompression obviously exists, leading to the problem of increased loss
