Innovation Solution
A top burner design featuring an outer burner with flame holes and an inner burner, along with a flame transfer slit to efficiently transfer flames and reduce imperfect combustion, ensuring uniform heating and effective fire transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a single burner is used, then the structure is simple, but the heating uniformity of food is poor
Solution Approach 1:
The burner is divided into multiple independent burners (first burner, second burner, third burner) arranged in different positions. Each burner has its own flame holes and can operate independently or in combination, enabling uniform heating across different areas of the food container while maintaining relative structural simplicity through modular design.
2Productivity
If fire transfer between burners is not implemented, then the structure is simple, but the combustion efficiency is poor
Solution Approach 1:
A flame transfer passage is provided that allows flame from the first burner to transfer to the second burner, and from the second burner to the third burner. This intermediary structure enables sequential ignition and improves combustion efficiency by ensuring complete burning of gas, while the passage design integrates smoothly into the existing burner structure.
3Productivity
If flame transfer between burners is implemented, then the combustion efficiency is improved, but the risk of food-induced combustion increases
Solution Approach 1:
The flame transfer passage is designed as a separate, dedicated channel that extracts the flame transfer function from the main combustion area. This isolated pathway prevents food placed on the burner surface from interfering with the flame transfer process, eliminating the risk of food-induced combustion while maintaining improved combustion efficiency.
4Temperature
If multiple burners are used, then the heating uniformity is improved, but the gas mixing and combustion control becomes difficult
Solution Approach 1:
Multiple burners share common gas supply channels and control mechanisms, merging the control functions into a unified system. This allows simultaneous operation of multiple burners with coordinated gas flow distribution, maintaining heating uniformity across different zones while simplifying operation through centralized control.
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 achieves uniform heating of food and reduces imperfect combustion, enhancing cooking efficiency and operational reliability by effectively transferring flames between burners.
Implementation Method 1
a first burner provided with a plurality of flame holes that form flame by combusting mixed gas; a second burner provided with a plurality of flame holes that form flame by combusting the mixed gas
Implementation Method 2
a flame transfer slit transferring the flame formed through the flame holes of the first burner to the second flame holes of the second burner

AI summary
A top burner and a cooker having the top burner are provided. A flame transfer slit for guiding the flame formed by the combustion of the mixed gas at an outer burner to an inner burner. A shielding member is provided to shield the flame transfer slit. Therefore, the object to be heated is uniformly heated and the flame transfer from the outer burner to the inner burner can be effectively realized.
