Gas Stove Burner Cap with Segmented Rings for Uniform Heat
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gas stove burners experience uneven heating due to large areas without combustion points, leading to low temperatures and increased gas consumption, which affects cooking efficiency and taste.
Innovation Solution
A burner cap design with multiple burner rings distributed evenly around the cap body, including a structure for secondary air supply, enhances combustion efficiency and reduces CO and NOx emissions by ensuring uniform flame distribution and adequate air supplementation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If additional burners are arranged on the peripheral edge of the outer burner cap, then heat output is improved, but large areas without combustion points remain between the combustion rings
Solution Approach 1:
The burner cap is divided into multiple combustion rings with burners distributed across different levels and circumferential positions. The burners are segmented into inner and outer combustion rings, with each ring containing multiple burners spaced around the circumference, ensuring comprehensive coverage of the burner cap surface.
Solution Approach 2:
Burners are arranged not only in the circumferential direction but also in the radial direction at different distances from the center. This multi-dimensional arrangement creates overlapping combustion zones that eliminate dead areas, ensuring every region of the burner cap contributes to heating.
2Ease of manufacture
If large areas are allocated free of combustion points, then manufacturing is simplified, but uneven heating occurs on the container underside
Solution Approach 1:
Different regions of the burner cap are equipped with burners according to their specific heating requirements. The density and arrangement of burners are optimized for each local area, ensuring that regions requiring more heat receive correspondingly more combustion points, while maintaining manufacturing feasibility.
3Productivity
If more combustion rings are implemented, then heating efficiency is improved, but device complexity increases
Solution Approach 1:
Multiple combustion rings and their associated burners are integrated into a single burner cap structure. The inner and outer combustion rings share common support elements and gas supply pathways, reducing the number of separate components and simplifying assembly while maintaining the multi-ring combustion configuration.
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
The solution provides improved heat output, reduced emissions, and more efficient combustion, resulting in faster cooking times and better taste, while simplifying production and installation.
Implementation Method 1
external and internal combustion points are typically arranged on the upper side... additional burners arranged in a ring shape on its peripheral edge facing the inner burner cap... areas without combustion points between the combustion rings
Implementation Method 2
conveying troughs 7 for secondary air... during operation of the burner, the secondary air can flow into this cavity... and thus be guided into the lower area of the burners that are in operation

AI summary
The present invention relates to a burner cap for gas stoves and a gas stove burner with such a burner cap. According to the invention, a burner cap for gas stoves is proposed, comprising a cap body (1) that is approximately circular and has a base (9), wherein a concave gas receiving chamber is formed on the underside of the cap body and several combustion points (3) penetrating the cap body are arranged on the cap body, characterized in that at least one concentrically arranged, pointed projection (4) is located on the base, which comprises at least two separate, pointed sections, wherein each of the sections has an outwardly chamfered surface (5) facing away from the circular center of the cap body, on which the combustion points (3) are located.Such a burner cap allows for a more even distribution of the combustion points on the burner cap of the gas stove, resulting in a more even flame distribution and better heating performance during burner operation.
