Cold Air Guide With Inclined Ribs for Uniform Ice Making
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ice making in refrigerators is inefficient due to non-uniform cold air distribution, leading to longer ice production times.
Innovation Solution
The implementation of a cold air guide system within the ice making compartment that directs and distributes cold air uniformly across the ice making tray, utilizing inclined guide ribs and a hollow guide body to concentrate and redirect cold air flow effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If cold air is introduced into the ice making compartment without guidance, then the ice making compartment receives cold air, but the cold air distribution is non-uniform and ice making time is extended
Solution Approach 1:
The cold air guide acts as an intermediary device between the cold air inlet and the ice making tray. It receives cold air from the inlet and redirects it toward the tray, ensuring uniform distribution. The guide body with its specific geometry (inclined guide ribs, curved surfaces) mediates the airflow path, transforming the non-uniform cold air flow into a uniform distribution pattern that accelerates ice making while reducing time loss.
2Manufacturing precision
If cold air is introduced directly without guidance, then the structure is simple, but the cold air distribution uniformity is poor
Solution Approach 1:
The cold air guide implements local quality by creating different geometric features at different locations within the guide body. The inclined guide ribs are positioned specifically to redirect airflow at certain angles, while curved surfaces are located to enhance flow uniformity. This localized geometric variation ensures uniform cold air distribution across the ice making tray without requiring a completely complex overall structure.
