Extractor Hood Outlet Grille with Rotatable Air Direction Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing extractor hoods lack the ability to adapt to varying spatial conditions in kitchens, such as different ceiling heights and wall positions, leading to impaired performance and user discomfort due to inefficient air discharge.
Innovation Solution
The outlet grille of the extractor hood can be adjusted in angular positions using bayonet connections or screw slots, allowing for flexible alignment and orientation to direct air flow away from the user and optimize efficiency, even in compact kitchens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the outlet grille is fixed in a single position, then the structure is simple and easy to manufacture, but the extractor hood cannot adapt to varying spatial conditions in different kitchens
Solution Approach 1:
The outlet grille is designed to be rotatable about a vertical axis, allowing it to change its angular position dynamically. This enables the air discharge direction to be adjusted according to the specific spatial conditions in different kitchens, such as ceiling height and wall position, thereby resolving the contradiction between adaptability and structural simplicity.
2Ease of operation
If the outlet grille aligns directly with the fan outlet, then the air flow resistance is minimized, but the air flow may be directed towards the user causing discomfort
Solution Approach 1:
The rotatable outlet grille allows the air discharge direction to be dynamically adjusted. By rotating the grille to different angular positions, the system can optimize the balance between user comfort and air discharge efficiency, directing air away from the user while maintaining effective ventilation.
3Adaptability or versatility
If the outlet grille is designed with adjustment mechanisms, then it can accommodate diverse kitchen layouts, but the manufacturing complexity and cost increase
Solution Approach 1:
The adjustment mechanism is designed as a simple rotation about a vertical axis, which can be implemented with minimal mechanical components. This approach provides the necessary adaptability for diverse kitchen layouts while keeping the manufacturing process relatively simple and cost-effective.
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
This adjustment enhances user comfort by preventing direct air flow towards the user and improves extractor hood efficiency by reducing flow resistance, accommodating diverse kitchen layouts and user preferences.
