Cooking Container Airflow Holes for Uniform Hot-Air Recirculation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous cooking apparatuses fail to distribute heat uniformly within the cooking compartment, leading to inhomogeneous cooking and inefficient energy use due to the conformation of return exits and internal container barriers.
Innovation Solution
The apparatus features a suction mouth connected to through holes on the lateral and base walls of the internal container, allowing for a forced circulation of hot air that recirculates and distributes heat uniformly across the food, with holes extending along the container's height and arranged in overlapping rows.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the return exit is positioned in the upper part of the cooking chamber without through holes in the internal container, then the structure is simple, but the hot air flow does not penetrate through the food, resulting in non-uniform cooking and excessive energy consumption
Solution Approach 1:
The invention divides the internal container into multiple sections by creating through holes in its walls. These holes segment the container's interior space, allowing hot air to pass through different zones of the food rather than flowing along a single surface path, thereby achieving uniform cooking while maintaining structural simplicity
Solution Approach 2:
The invention transitions from surface-level hot air circulation to three-dimensional penetration by introducing vertical through holes through the container walls. This dimensional change enables hot air to flow through the depth of the food, not just across the surface, resolving the contradiction between simple structure and uniform cooking
2Object-affected harmful factors
If the internal container acts as a barrier to protect food, then food protection is improved, but the hot air flow path is constrained, preventing deep penetration and causing non-uniform cooking
Solution Approach 1:
The internal container is transformed from a solid barrier into a porous structure with through holes. This allows the container to simultaneously protect food (by containing it) and permit hot air penetration (by providing flow paths through the walls), resolving the contradiction between protection and heat distribution
3Manufacturing precision
If through holes are added to the internal container to improve heat distribution, then cooking uniformity is improved, but the device complexity increases
Solution Approach 1:
The container structure is segmented into multiple zones defined by the through holes, allowing independent control of hot air flow paths. This segmentation achieves uniform cooking across different food layers while the modular nature of the holes keeps the manufacturing process relatively simple
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 solution ensures uniform heating of food, optimizing cooking results and reducing energy consumption by ensuring all parts of the food are evenly cooked and energy is used efficiently.
Implementation Method 1
at least one heating device
Implementation Method 2
at least one element to generate a flow of air to the food... the flow of air must be distributed uniformly inside the container and between the food
