Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing burner designs for cooktops often have complex structures with multiple burner caps, leading to increased production costs and difficulty in cleaning, while lacking independent control over inner and outer-ring fires and inefficient fire spread.
Innovation Solution
Integration of inner-ring and outer-ring burner holes on a single burner cap, with oblique orientations and flame-stabilizing grooves, allowing independent control and efficient fire spread without additional structures, and utilizing separate chambers and ejector tubes for gas stabilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple burner caps are used for inner-ring and outer-ring burners, then independent control of inner and outer-ring fires is achieved, but the structure becomes complex and production efficiency decreases
Solution Approach 1:
The burner cap is segmented into an inner-ring region and an outer-ring region with distinct burner holes and chambers, allowing independent control of inner and outer-ring fires while using a single integrated cap structure. The inner-ring burner holes communicate with the inner-ring chamber, and outer-ring burner holes communicate with the outer-ring chamber, enabling functional independence without structural multiplication.
Solution Approach 2:
The patent merges the inner-ring burner cap and outer-ring burner cap into a single integrated burner cap structure. This unified design reduces the number of separate components while maintaining the functional separation needed for independent control of inner and outer-ring combustion zones.
2Adaptability or versatility
If multiple burner caps are used, then independent fire control is possible, but cleaning convenience deteriorates
Solution Approach 1:
By combining the inner-ring and outer-ring burner caps into one integrated structure, the patent creates a unified surface that is easier to clean compared to multiple separate caps. The planar top surface of the single burner cap allows for simplified maintenance while preserving independent fire control through the segmented chamber design.
3Productivity
If inner-ring and outer-ring burner holes are integrated on the same burner cap, then production efficiency improves, but fire spread efficiency may deteriorate
Solution Approach 1:
The patent positions the outer-ring burner holes above the inner-ring burner holes in the vertical dimension, creating a stacked arrangement on the same burner cap. This spatial configuration in the vertical dimension enables efficient fire spread from the inner-ring to outer-ring burners while maintaining production efficiency benefits of a single cap structure.
4Speed
If inner-ring burner holes extend obliquely upward, then fire spread to outer-ring burner holes is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent applies different orientation characteristics to different regions of the burner cap. The inner-ring burner holes extend obliquely upward at specific angles optimized for fire spread, while the outer-ring burner holes have their own orientation optimized for their position. This localized optimization of hole orientations achieves effective fire spread while allowing standard manufacturing processes to handle the precision requirements for each region independently.
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
Simplifies the burner cap structure, improves production efficiency, enhances cleaning convenience, and achieves stable, efficient fire spread and combustion, resulting in improved thermal and cooking performance.
Implementation Method 1
the inner-ring burner holes extend obliquely upward toward the central region of the burner cap, the inner-ring fire will gather toward the middle and upward, which is not only beneficial to spreading fire from the inner-ring burner holes to the outer-ring burner holes
Implementation Method 2
a circle of flame-stabilizing grooves connected end to end and facing a central region of the burner cap are circumferentially arranged on the inner side wall, and the flame-stabilizing grooves are in communication with the inner-ring chamber through the inner-ring burner holes

AI summary
A burner head for a cooktop, a burner, and a cooktop are provided. The burner head includes a burner cap and a burner cap base. The burner cap is covered on the burner cap base, the burner cap matches the burner cap base to form an inner-ring chamber and an outer-ring chamber, the burner cap is provided with a plurality of inner-ring burner holes in communication with the inner-ring chamber and a plurality of outer-ring burner holes in communication with the outer-ring chamber, the burner cap includes an inner side wall and an outer side wall disposed opposite to each other, and the burner cap further includes a centripetal ring-shaped top wall located between the inner side wall and the outer side wall and extending obliquely downward, characterized in that the inner-ring burner holes are circumferentially arranged spaced apart on the inner side wall, and the outer-ring burner holes are circumferentially arranged spaced apart on the ring-shaped top wall. The inner-ring burner holes and the outer-ring burner holes are integrated and arranged on the same burner cap, so that a quantity of burner caps is reduced, which not only simplifies the structure of the burner head, but also helps to improve the production efficiency of the burner cap and even the entire cooktop. In addition, fire can be spread without using a complex fire spread structure.
