Scroll Compressor Variable-Capacity Member Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scroll compressors are complex and have a worsened outer appearance due to the need for external valves, pipes, and separate flow paths, making installation inconvenient.
Innovation Solution
A scroll compressor design that integrates a variable-capacity member within the housing, allowing refrigerant to bypass from the compression chamber to the suction space through a flow path distribution portion and valve portion, eliminating the need for external components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If external valves, pipes, and separate flow paths are used to enable capacity variation, then the compressor can vary its capacity, but the device complexity increases and the outer appearance is worsened
Solution Approach 1:
The patent merges the valve and flow path distribution functions into an integrated variable-capacity member that is built inside the housing. This combines multiple external components (valve, pipes, separate flow paths) into a single integrated component, reducing device complexity while maintaining capacity variation capability
Solution Approach 2:
The variable-capacity member is nested within the housing, with the flow path distribution portion and valve portion integrated inside the compressor body. This nesting approach eliminates external components and simplifies the overall configuration while enabling capacity variation
2Adaptability or versatility
If external valves and pipes are installed for capacity control, then capacity variation is enabled, but the ease of manufacture decreases and installation becomes inconvenient
Solution Approach 1:
By merging the valve and flow path distribution into a single integrated variable-capacity member, the patent reduces the number of separate components that need to be manufactured and assembled. This integration simplifies the manufacturing process and improves installation convenience while maintaining capacity variation functionality
3Adaptability or versatility
If a complex controller is used to control rotational speed for capacity variation, then capacity can be varied, but the device complexity increases
Solution Approach 1:
The patent extracts the capacity control function from the rotational speed control approach. Instead of using a complex controller to adjust rotational speed, the invention uses a simpler variable-capacity member with a valve that can be directly controlled to bypass refrigerant, eliminating the need for complex rotational speed control electronics

AI summary
The present invention provides a scroll compressor and a manufacturing method therefor, the scroll compressor comprising: a housing having a suction space in which a flow path, into which a refrigerant is suctioned, is formed and a flow path accommodation space allowing communication between a compression chamber and the suction space; a rotary shaft provided inside the housing so as to rotate; a compression part having an orbiting scroll orbitally provided at the rotary shaft and a fixed scroll coupled to the orbiting scroll so as to engage therewith, thereby forming the compression chamber between the fixed scroll and the orbiting scroll so that the refrigerant can be discharged; and a variable-capacity member which is provided in the housing so as to allow communication with the flow path accommodation space, and which can open/close at least a portion of the flow path provided therein, so that some of the refrigerant compressed in the compression chamber can make a detour to the suction space through the flow path accommodation space inside the housing.
