Ventilation apparatus and air conditioner including the same
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ventilation apparatuses for air conditioners face challenges with contamination of the ventilation pipe due to dust and maintenance difficulties, including cumbersome filter cleaning or replacement.
Innovation Solution
The ventilation apparatus includes a detachable extension tube with a cup-shaped air filtering part that gradually decreases in diameter, providing a larger filtration area while minimizing pipe contamination and facilitating easy maintenance by allowing the filter to be inserted into the ventilation pipe through a connection portion between the inlet and extension tubes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the filter is built into the main body of the ventilation apparatus, then the filtration function is provided, but the ventilation pipe inner surface is contaminated by dust and maintenance becomes cumbersome
Solution Approach 1:
The filter is separated from the main body and positioned independently within the ventilation pipe. The filter can be removed and installed separately without disassembling the main body, allowing easy maintenance while maintaining the filtration function.
Solution Approach 2:
The filter is extracted from the main body structure and placed as a separate component in the ventilation pipe. This extraction allows the filter to be easily removed for cleaning or replacement without affecting the main body or other components.
2Ease of manufacture
If a traditional filter structure is used, then filtration is provided, but the filtration area is limited and flow resistance increases
Solution Approach 1:
The filter adopts a cylindrical shape that extends along the ventilation pipe axis, utilizing the longitudinal dimension of the pipe. This dimensional approach significantly increases the filtration surface area compared to traditional flat filters, improving both filtration capacity and air flow efficiency.
Solution Approach 2:
The filter is designed to be inserted into the ventilation pipe, with the filter structure nested within the pipe's internal space. The filter's cylindrical shape allows it to fit snugly within the pipe diameter, maximizing the use of available space while maintaining large filtration area.
