Bent Oven Gas Burner Layout for Uniform Chamber Heating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Straight tubular gas burners in oven appliances occupy valuable space, cause unbalanced heating, and lead to excessive radiant heat transfer, material degradation, and temperature differences within the cooking chamber, affecting baking and self-clean performance.
Innovation Solution
A bent gas burner tube configuration is used, with elongated portions positioned below the floor panel at side and front portions, distributing heat more uniformly and conserving space by recessing the central area of the floor panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a straight tubular gas burner is used, then the burner structure is simple, but the burner occupies large volume space below the cooking chamber
Solution Approach 1:
The gas burner tube is bent into a curved configuration that extends along the side walls and front/rear portions of the cooking chamber, utilizing the lateral and depth dimensions more efficiently. This dimensional redistribution allows the burner to achieve adequate heating coverage while reducing the vertical profile and occupying less volume space below the cooking chamber compared to a straight tubular design.
2Ease of manufacture
If a straight tubular gas burner is used, then the burner installation is simple, but the heating distribution becomes unbalanced with excessive heat at the center
Solution Approach 1:
The bent gas burner tube positions combustion outlets at specific locations along the side walls and front/rear portions of the cooking chamber, creating localized heating zones that distribute heat more uniformly. This non-uniform spatial distribution of heat sources compensates for the natural tendency toward center concentration, achieving balanced heating without requiring complex installation procedures.
3Use of energy by moving object
If the floor panel is positioned close to the burner, then the heating efficiency is high, but the floor panel temperature becomes excessively high causing radiant heat transfer and material degradation
Solution Approach 1:
The bent gas burner tube configuration acts as an intermediary heat distribution system, positioning combustion outlets to deliver heat directly to the cooking chamber air and surfaces rather than concentrating it on the floor panel. This indirect heating approach maintains heating efficiency while preventing excessive floor panel temperatures that would cause harmful radiant heat transfer and material degradation.

AI summary
An oven appliance with a cabinet having a cooking chamber is provided. A floor panel is positioned within the cabinet at the cooking chamber. A gas burner includes a tube. The tube is bent such that a first elongated portion of the tube is positioned below the floor panel at a first side portion of the floor panel and a second elongated portion of the tube is positioned below the floor panel at a front portion of the floor panel.
