Extractor Hood with Removable Inner Element for Easy Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing extractor hoods are difficult to clean due to housing parts being exposed to incoming air, making it challenging to access and maintain the internal components effectively.
Innovation Solution
An elastically deformable plastic inner element is used to cover the distance between the intake and outlet openings of the viewing hood, allowing for easy detachment and cleaning, with features like air guiding elements to improve airflow and reduce turbulence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If housing parts are exposed to incoming air in existing extractor hoods, then air can be guided from intake to outlet opening, but the housing parts become difficult to access and clean
Solution Approach 1:
The housing is divided into a removable inner element and a stationary outer housing. The inner element can be detached for cleaning while the outer housing remains in place, solving the contradiction between exposed housing parts and cleanability.
Solution Approach 2:
The inner element is extracted as a separate removable component from the housing. This allows the inner element to be taken out for cleaning without disassembling the entire housing structure, improving accessibility while maintaining structural integrity.
2Ease of operation
If an inner element is added to cover the distance between intake and outlet openings, then cleaning becomes easier, but the device structure becomes more complex
Solution Approach 1:
The inner element combines multiple functions: it serves as a structural component guiding air from intake to outlet opening, and simultaneously as a removable cleaning element. This merging reduces the need for additional separate components.
Solution Approach 2:
The inner element is designed to perform multiple functions: structural support, air guidance, and easy cleaning access. This multi-functionality reduces overall device complexity while improving maintainability.
3Ease of operation
If the inner element is made of elastically deformable plastic, then detachment force is reduced for easier cleaning, but the structural strength may be compromised
Solution Approach 1:
The inner element is made of elastically deformable plastic, allowing it to flex during attachment and detachment. This flexibility reduces the force required for removal while maintaining sufficient structural strength for normal operation.
Solution Approach 2:
The material properties of the inner element are optimized to have specific elastic characteristics. The material is chosen to provide adequate strength during operation while allowing easy detachment when cleaning is required, balancing strength and ease of removal.
