External Dust Charging Layout for Air Cleaner Flow Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioning apparatuses have suboptimal air cleaning performance due to the placement of the ionizing part, which causes flow resistance and inefficient space usage, leading to decreased air conditioning efficiency.
Innovation Solution
An air conditioning apparatus with an electric charge device positioned outside the main body to charge dust particles, coupled with a filter device using dielectric barrier discharge for dust collection and a power source that applies different frequencies for cleaning, allowing for improved dust collection and user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the ionizing part is disposed at a rear side of the suction part, then the structure is simplified, but air cleaning performance deteriorates and flow resistance increases
Solution Approach 1:
The ionizing part is extracted from the main body and disposed outside the air conditioning apparatus. This allows the ionizing function to be separated from the airflow path, eliminating the flow resistance problem while maintaining air cleaning performance. The ionizing part can be positioned independently to optimize both structural simplicity and cleaning efficiency.
2Volume of stationary object
If the ionizing part is disposed inside the main body, then space occupancy is reduced, but the apparatus size increases when the ionizing part is enlarged
Solution Approach 1:
The ionizing part is extracted from the main body and positioned externally. This allows the main body to maintain a compact size while the ionizing part can be sized appropriately for optimal performance without constraining the overall apparatus dimensions. The external positioning resolves the conflict between internal space constraints and ionizing part size requirements.
3Volume of stationary object
If the ionizing part is disposed at the rear side, then installation space is saved, but only a portion of air passes through the ionizing part
Solution Approach 1:
The ionizing part is extracted and positioned outside the main body where it can process air more effectively. The external positioning allows for better air flow through the ionizing part without restricting the main body's internal space, thereby improving the proportion of air that receives ionization treatment while maintaining compact installation dimensions.
