Multi-Burner Cooktop Control for Even Griddle Heat Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cooktop appliances with multiple gas burners face challenges in evenly heating a griddle due to uneven heat distribution, leading to 'hot spots' and difficulties in balancing heat output, which can result in uneven cooking and potential overheating.
Innovation Solution
A cooktop appliance with a panel featuring two burner assemblies and control valves, allowing for single-burner or multi-burner modes, where the controller independently or cooperatively positions the valves to manage gas flow and heat output across multiple burners for even griddle heating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple gas burners are used to heat a griddle, then the heating area is increased, but heat distribution becomes uneven creating hot spots
Solution Approach 1:
The patent combines multiple burner assemblies (first and second burners) to operate cooperatively as a single heating unit. The controller synchronizes the operation of multiple burners to function as one integrated heat source, distributing heat more evenly across the griddle surface and eliminating hot spots while maintaining increased heating area.
2Adaptability or versatility
If multiple burners operate independently, then each burner can be controlled separately, but balancing heat output becomes difficult
Solution Approach 1:
The controller monitors and regulates the operation of multiple burner assemblies, adjusting their individual outputs to achieve balanced heat distribution. By implementing control feedback mechanisms, the system automatically compensates for variations in burner performance, making heat balancing straightforward while preserving independent control capability for each burner.
3Area of stationary object
If an integrated griddle is used over multiple burners, then heat coverage is improved, but airflow to burners is blocked
Solution Approach 1:
The griddle is designed as a segmented or modular structure that allows airflow to pass through or around it to the burner assemblies. By dividing the griddle into sections with airflow channels or gaps, the system maintains adequate oxygen supply for combustion while still providing broad heat coverage across the cooking surface.
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 consistent and even heat distribution across a griddle placed over multiple burners, preventing overheating and ensuring uniform cooking results.
Implementation Method 1
The heated portions utilize one or more heating sources to output heat... burners may be included with each heated portion
Implementation Method 2
The first control valve may be in fluid communication with the first burner assembly to selectively direct a flow of gas thereto
