Compressor Side Felt Structure for Terminal Block Noise Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Noise leakage from air conditioner compressors, particularly due to gaps between the side felt and terminal block cover, compromises noise blocking efficiency and serviceability.
Innovation Solution
A noise blocking device with a side felt structure that includes a terminal block cover felt and a holding member, such as a belt, to maintain the shape and reduce gaps, ensuring effective noise isolation while allowing for easy assembly and disassembly of the terminal block cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a side felt structure with an opening for the terminal block is used, then serviceability is improved, but noise leakage increases
Solution Approach 1:
The side felt is divided into two functional parts: a main body portion that surrounds the compressor for noise blocking, and a separate terminal block cover felt that can be opened or closed. This segmentation allows the terminal block area to be accessible when needed while maintaining noise isolation when closed.
Solution Approach 2:
The terminal block cover felt is designed to be movable between open and closed positions, allowing dynamic adjustment between serviceability (open) and noise blocking (closed) modes, rather than being a fixed structure.
2Ease of manufacture
If a gap is provided between the opening and cover, then assembly is simplified, but noise blocking performance deteriorates
Solution Approach 1:
The terminal block cover felt uses a flexible felt material that can be molded into a cover shape. This flexible material allows for easier assembly while still providing effective noise blocking when properly positioned, replacing rigid structures that would require precise gaps.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances noise blocking performance by minimizing leakage through the side felt opening and facilitates serviceability by maintaining the shape of the side felt, thus reducing noise emission and maintaining terminal block accessibility.
Implementation Method 1
a holding member comprising a belt disposed in an area around the opening and having a fixed end configured to be fixed to the area around the opening and a free end configured to provide a force maintaining a shape of the side felt
Implementation Method 2
felt with high noise-absorption performance may be applied to the outer circumferential surface of the compressor

AI summary
Various embodiments of the present disclosure relate to a side felt structure applied to reduce noise emitted from a compressor in an air conditioner. To this end, a device for reducing noise of an air conditioner may comprise: a terminal block disposed to protrude from the outer peripheral surface of a compressor; a side felt disposed to encompass the compressor, and including an opening allowing the terminal block to be seen from the outside; and a terminal block cover felt extending from one side of the opening formed in the side felt, so as to open/close at least a portion of the opening.
