Elevated Gas Burner Support Frame With Top-Breathing Airflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gas cooktops face issues with debris accumulation and cleaning difficulties around gas burners due to their proximity to the cooktop floor, leading to discoloration and restricted airflow, which affects flame performance and appearance.
Innovation Solution
A cooking vessel support system with a support frame that elevates the gas burner above the cooktop floor, incorporating an internal passageway to draw primary air from above and mix it with injected gas, providing a 'top-breathing' burner configuration that minimizes interference from internal airflow and allows for easier cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the gas burner is disposed on the cooktop floor or on a pedestal, then the burner is supported and positioned, but debris accumulates around the burner and pedestal making cleaning difficult
Solution Approach 1:
The gas burner is elevated from the cooktop floor to a higher position in the vertical dimension, supported by a cooking vessel support system. This vertical separation creates clearance between the burner and cooktop surface, preventing debris accumulation in the intersection areas and enabling easier cleaning of the cooktop floor.
2Ease of manufacture
If the gas burner is close to the cooktop floor, then the burner is compact and easy to install, but the flame heats and bakes debris onto the cooktop floor causing discoloration
Solution Approach 1:
The burner is positioned in the vertical dimension above the cooktop floor, creating sufficient clearance to prevent the flame from directly heating and baking debris onto the cooktop surface. This vertical separation eliminates the discoloration problem while maintaining a compact overall structure.
3Device complexity
If the gas burner is close to the cooktop floor, then the structure is compact, but secondary air availability is restricted affecting flame performance
Solution Approach 1:
Elevating the burner in the vertical dimension creates additional space for secondary air to reach the burner from above the cooktop floor. The internal passageways are configured to draw secondary air from this elevated position, ensuring adequate airflow for proper combustion and flame performance while maintaining structural compactness.
4Stability of the object's composition
If the cooking vessel support is fixed, then the structure is stable, but the cooktop floor and burner components are difficult to clean and maintain
Solution Approach 1:
The cooking vessel support system is designed to be removable rather than fixed, allowing it to be dynamically repositioned. The support can be easily removed from the cooktop floor to provide access for cleaning the floor and for maintenance of the burner components, then reinstalled to provide structural stability during cooking operations.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances cleanability, maintains a visually appealing appearance by reducing debris accumulation, and improves flame production and performance by ensuring proper airflow and separation from the cooktop floor.
Implementation Method 1
The support frame includes an internal passageway in fluid communication with the gas burner and configured to draw primary air into the support frame at a location above the cooktop floor and to mix the primary air with an injected gas to provide an air-gas mixture

AI summary
A cooking appliance is provided, including a cooktop floor and a removable cooking vessel support system on the cooktop floor. The cooking vessel support system includes a support frame configured to support a cooking vessel above a gas burner, the support frame having at least a first arm supporting the gas burner above and spaced apart from the cooktop floor. The support frame includes an internal passageway in fluid communication with the gas burner and configured to draw primary air into the support frame at a location above the cooktop floor and to mix the primary air with an injected gas to provide an air-gas mixture. At least a portion of the internal passageway is formed in the first arm of the support frame such that the air-gas mixture is guided by the internal passageway through the first arm to the gas burner.
