Multi-level gas burner having ultra low simmer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gas burners typically fail to provide both high heat output and ultra-low simmer capabilities simultaneously, lacking sufficient control over heat output and distribution.
Innovation Solution
A multi-level gas burner with separate, individually controllable gas supplies for each level, utilizing a multi-valve system to adjust heat distribution by changing the air-gas mixture supply to the lower and upper burner sections, allowing for independent operation of dual flame rings to achieve a wide range of heating options from 500 BTU to 22,000 BTU or greater.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a conventional gas burner is designed for high heat output, then it can provide high power cooking (22,000 BTU or greater), but it cannot provide ultra-low simmer capabilities (500 BTU)
Solution Approach 1:
The burner is divided into two separate burner sections: an upper burner section for high power cooking and a lower burner section for ultra-low simmer. Each section has its own separate air-gas mixture supply system, allowing independent control of flame intensity and height. This segmentation enables the burner to provide both high heat output (22,000+ BTU) and ultra-low simmer (500 BTU) capabilities simultaneously or independently.
2Adaptability or versatility
If a separate simmer burner is added to provide low BTU output, then ultra-low simmer capability is achieved, but device complexity increases
Solution Approach 1:
The patent merges two separate burner functions (high power cooking and ultra-low simmer) into a single integrated burner assembly. The upper and lower burner sections are vertically stacked and share a common body structure, while maintaining separate air-gas mixture supplies. This merging approach provides dual functionality without requiring two completely separate burner units, thus limiting the increase in device complexity.
3Adaptability or versatility
If a gas burner cycles on/off to reduce heat output, then simmer functionality is achieved, but heat distribution control is insufficient
Solution Approach 1:
The lower burner section can be dynamically adjusted in height relative to the upper burner section, allowing continuous variation of flame position and heat distribution pattern. This dynamic adjustment capability provides smooth transition between different heat output levels and patterns, enabling precise control from ultra-low simmer to high power cooking without relying on simple on/off cycling.
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 design provides greater control over heat output and distribution, minimizing the risk of scorching by enabling precise adjustment of heat intensity and location, thus offering a broader range of cooking options.
Implementation Method 1
a first air-gas mixture for the lower burner section and a second injection point for receiving a second air-gas mixture for the upper burner section

AI summary
A cooking appliance is provided, including a multi-level gas burner with a body having a lower burner section on a lower side and an upper burner section on an upper side. The lower burner section is separated from the upper burner section. The lower side of the body has a first injection point for receiving a first air-gas mixture for the lower burner section and a second injection point for receiving a second air-gas mixture for the upper burner section. The first injection point is partitioned from the second injection point thereby separating the first air-gas mixture from the second air-gas mixture. The body includes a passageway fluidly connecting the second injection point on the lower side of the body to the upper burner section on the upper side of the body.
