Compressor Muffling Chamber Across Multiple Members
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing compressor designs face limitations in effectively reducing noise generated by the compression mechanism due to restricted muffling space, which is constrained by the sizes of components.
Innovation Solution
The compressor incorporates a muffling chamber formed across multiple members, allowing for a larger muffling space and improved noise reduction by increasing the size of the muffling chamber in the direction where members overlap, thereby enhancing the noise reduction effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the muffling chamber is formed within a single component, then the structure is simple, but the muffling space is restricted and noise reduction effect is insufficient
Solution Approach 1:
The muffling chamber is segmented across multiple components (cylinders and intermediate partition plate) rather than being contained within a single component. This segmentation allows the total muffling volume to be distributed across several parts, achieving a larger overall muffling space while maintaining structural simplicity through the modular arrangement of existing components.
Solution Approach 2:
The muffling chamber is formed by merging the internal spaces of multiple components (upper cylinder, lower cylinder, and intermediate partition plate). By combining the void spaces of these separate components into a unified muffling chamber, the patent achieves a larger total muffling volume without adding separate dedicated muffling components.
2Object-affected harmful factors
If the muffling chamber size is increased, then the noise reduction effect is improved, but the component sizes must be increased accordingly
Solution Approach 1:
By merging the internal spaces of multiple existing components into a shared muffling chamber, the patent achieves a larger total muffling volume without proportionally increasing the size of individual components. The combined void space of multiple components creates an enlarged muffling chamber that would be difficult to achieve within a single component of comparable size.
3Object-affected harmful factors
If the communication hole diameter is increased to reduce noise, then the noise is reduced, but the component size is constrained by manufacturing limitations
Solution Approach 1:
The noise reduction function is segmented across multiple components forming the muffling chamber, rather than relying on a single large communication hole. This allows each component to maintain its standard manufacturing dimensions while the collective arrangement of multiple components achieves the desired noise reduction through a larger distributed muffling volume.

Function Achieved in This Case
This configuration effectively reduces noise in the compression mechanism by increasing the transmission loss of sound frequencies, particularly in the range of 1 kHz or less, leading to improved noise suppression.

AI summary
A compressor (1) includes a drive mechanism (10) and a compression mechanism (100) that is driven by the drive mechanism (10). The compression mechanism (100) has a discharge passage (P) in which a refrigerant compressed in the compression mechanism (100) flows, and a plurality of members (40, 50, 60, 70, 80) disposed to overlap each other. The discharge passage (P) includes a muffling chamber (M), an inflow passage (I) connected to the inflow end of the muffling chamber (M), and an outflow passage (O) connected to the outflow end of the muffling chamber (M). The muffling chamber (M) is formed across two or more members of the plurality of members (40, 50, 60, 70, 80).
