Single Loop Burner Design for Uniform Heating in Cooking Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooking devices with burners lack uniform heating capabilities, leading to inefficient food cooking due to uneven flame distribution and heat collection.
Innovation Solution
A burner design featuring a combustion unit with a single loop shape, comprising an inner and outer part with strategically placed flame holes, ensures uniform fuel flow and flame generation, preventing heat accumulation in the middle and enhancing radiant heating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a conventional burner with multiple flame holes is used, then the burner structure is simple, but the heating uniformity deteriorates due to uneven flame distribution and heat accumulation in the middle
Solution Approach 1:
The combustion unit is divided into multiple combustion parts (first combustion part, second combustion part, etc.), each with its own flame holes. This segmentation allows independent control and optimization of flame generation in different regions, preventing heat accumulation in the middle and improving overall heating uniformity
Solution Approach 2:
The combustion unit is designed with a single loop shape configuration, transitioning from a simple linear or radial arrangement to a closed-loop dimensional structure. This allows flames to be distributed along the entire perimeter of the loop, creating uniform radiant heating from all directions and eliminating the heat accumulation problem in the center
2Productivity
If flame holes are spaced at predetermined distances in a conventional burner, then the manufacturing is simple, but the flame distribution becomes uneven causing inefficient cooking
Solution Approach 1:
The combustion unit is segmented into multiple combustion parts with flame holes distributed across different sections. Each combustion part contributes to the overall flame distribution, ensuring that flames are generated uniformly along the entire loop structure rather than relying on precise spacing of individual holes in a single structure
Solution Approach 2:
Different combustion parts are positioned to create appropriate flame density in different local regions. The single loop shape ensures that each section of the loop receives appropriate fuel flow and generates proportional flame output, achieving local optimization of flame distribution that collectively produces uniform overall heating
3Stability of the object's composition
If a single loop shaped combustion unit is implemented, then uniform heating is achieved, but the device complexity increases
Solution Approach 1:
Multiple combustion parts are merged into a single integrated loop-shaped combustion unit. This merging combines the functions of multiple separate burners into one unified structure, achieving uniform heating through the loop configuration while maintaining a compact and integrated design that does not excessively increase device complexity
