Compressor Soundproof Cover With Accessible Terminal Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing soundproof covers for compressors in air-conditioning apparatuses hinder the efficient connection of cables to terminal units, as they cover the terminal units, leading to decreased workability.
Innovation Solution
A design that includes a terminal unit on the compressor's outer surface for electrical connections, a side soundproof cover that leaves the terminal unit exposed, and a detachable terminal cover that can be attached to the side soundproof cover to provide soundproofing while allowing easy access for cable connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the entire compressor is covered with a soundproof cover, then sound insulation is improved, but cable connection workability deteriorates
Solution Approach 1:
The soundproof cover is divided into a main body cover and a separate terminal cover. The main body cover covers the compressor, while the terminal cover is detachably attached to expose the terminal unit for cable connection. This segmentation allows independent access to the terminal unit without removing the entire soundproof cover, resolving the contradiction between sound insulation and cable connection workability.
Solution Approach 2:
The terminal cover is designed to be detachably attached to the main body cover, allowing the coverage state of the terminal unit to change dynamically. When cable connection is needed, the terminal cover can be removed to expose the terminal unit; when not needed, it can be attached to maintain sound insulation. This dynamic adjustability resolves the contradiction between maintaining sound insulation and enabling cable connection access.
2Object-affected harmful factors
If the terminal unit is covered with the soundproof cover, then soundproofing is improved, but accessibility for cable connection deteriorates
Solution Approach 1:
The soundproof cover is segmented into a main body cover for the compressor and a separate terminal cover for the terminal unit. This allows the terminal unit to be covered when needed for soundproofing while enabling easy exposure by removing only the terminal cover for cable connection, maintaining both soundproofing and accessibility.
Solution Approach 2:
The terminal cover is extracted as a separate detachable component from the main body cover. This extraction allows the terminal unit to be selectively covered or exposed independent of the main compressor coverage, achieving both soundproofing when covered and accessibility when the terminal cover is removed.

AI summary
An outdoor unit of an air-conditioning apparatus includes: a terminal unit that is provided on an outer peripheral surface of a compressor, and electrically connects components provided in the compressor and outside the compressor; a side soundproof cover that covers the outer peripheral surface of the compressor except for the terminal unit; and a terminal cover that covers the terminal unit exposed from the side soundproof cover to the outside of the side soundproof cover, and soundproofs the terminal unit. The terminal cover is attached to the side soundproof cover such that the state of the terminal cover can be changed between a state in which the terminal cover covers the terminal unit and a state in which the terminal cover does not cover the terminal unit.
