Oven Burner Cover Layout for Cleanable Convective Heating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cooking devices, such as oven ranges, face issues with contamination and cleaning due to the open bottom surface that allows food leftovers to enter the burner chamber, and the installation of a lower burner reduces cavity capacity.
Innovation Solution
A cooking device design featuring a frame with a burner and burner cover that includes a stabilizer with a body, barrier, and fastening unit to manage airflow and prevent contamination, while maintaining a closed bottom surface for improved cleaning and increased cavity capacity by positioning the burner assembly at the rear wall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the bottom surface of the oven chamber is open to allow air circulation for convective heating, then heating efficiency is improved, but food leftovers can enter the burner chamber causing contamination and cleaning difficulties
Solution Approach 1:
The oven chamber bottom surface is segmented into multiple air circulation holes rather than being completely open, allowing controlled air flow while preventing food leftovers from entering the burner chamber
Solution Approach 2:
A lower burner cover is introduced as an intermediary component between the oven chamber and the lower burner, featuring air circulation holes that enable heating efficiency while blocking contamination paths
2Productivity
If a lower burner is installed under the oven chamber to provide convective heating, then heating performance is improved, but the cavity capacity is reduced due to the burner installation space
Solution Approach 1:
The lower burner is repositioned from a vertical installation under the oven chamber to a horizontal installation at the rear wall, utilizing the depth dimension of the oven chamber to maintain cavity capacity while achieving convective heating performance
3Productivity
If the bottom surface of the oven chamber is open for air circulation, then convective heating is enabled, but cleaning the oven chamber becomes difficult
Solution Approach 1:
The bottom surface is segmented into discrete air circulation holes rather than being completely open, maintaining convective heating capability while providing a closed surface that is easier to clean
Solution Approach 2:
The lower burner cover serves as an intermediary structure that provides air circulation holes for heating while presenting a cleanable surface, separating the air flow function from the structural bottom 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

AI summary
A cooking device includes a frame to form a cooking chamber; a burner disposed in the cooking chamber and to generate a flame for supplying heat to the cooking chamber; a burner cover in which the burner is installed and having a plate with an outlet opening through which an air passes; a fan to flow an air of the cooking chamber; and a stabilizer to reduce an influence of the air on a flame of the burner when the air of the cooking chamber passes through the outlet opening of the burner cover by the fan. The stabilizer includes: a body having an opening for air passage; a barrier extended from the body; and a fastening unit for fastening the body to the burner cover, and while the fastening unit is fastened to the burner cover, the body is spaced apart from the plate of the burner cover.
