Internal Flame Burner Layout for Bottom-Focused Heating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional burners suffer from heat loss as the flame-generated heat flows along the sides of containers instead of being concentrated on the bottom, leading to inefficient heating of contents.
Innovation Solution
The burner design includes a first and second burner head with mixing pipes and a burner cap, where the gas mixture is supplied through a support wall and inner wall configuration, ensuring the flame is produced inside the burner and concentrated on the container bottom, with the second burner positioned to enhance heat distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If flame is produced at the side of the burner, then the container can be heated, but heat flows along the side of the container causing heat loss
Solution Approach 1:
The patent inverts the conventional burner design by producing the flame inside the burner body rather than at the side. The gas mixture is supplied through mixing pipes within the burner head, and the flame is generated internally, directing heat downward onto the container bottom. This inversion resolves the heat loss problem by concentrating thermal energy where it is needed most.
Solution Approach 2:
The burner design implements local quality by creating different functional zones: the inner wall region for flame generation, the support wall for structural support, and the downward-directed flame path for concentrated heating. The gas mixture is supplied locally through mixing pipes positioned to create an internal flame, ensuring heat is generated precisely where it can be most effectively transferred to the container bottom.
2Productivity
If flame is produced at the side of the burner, then cooking can proceed, but heat concentration on container bottom is poor
Solution Approach 1:
By inverting the flame production location from side-mounted to internal, the patent achieves superior heat concentration on the container bottom. The flame is generated within the burner head and directed downward, creating intense localized heating that accelerates cooking while improving thermal efficiency.
Solution Approach 2:
The patent transitions from horizontal/side flame delivery to vertical/downward flame delivery. The gas mixture is supplied horizontally through mixing pipes, but the flame is directed vertically downward onto the container bottom. This dimensional change in heat delivery optimizes thermal contact and concentration on 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 configuration ensures that heat is effectively concentrated on the bottom of the container, reducing heat loss and improving cooking efficiency by directing the flame to focus on the container's bottom.
Implementation Method 1
Gas is ejected from a nozzle and supplied, as a gas mixture including gas mixed with air, into the gas chamber, and burned as it is discharged through the flame holes, thereby producing flame

AI summary
A burner is provided. The burner may include a burner head having mixing pipes through which an air-gas mixture may flow, and a burner cap seated on the burner head and having an opening formed therein. The burner head may include a support wall along its periphery supporting the burner cap thereon and an inner wall formed within the periphery of the support wall, the inner wall having a plurality of flame holes. The center of the burner cap may be positioned within the opening.
