Partitioned Oven Burner Layout for Even Heat Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cooking appliances face challenges in evenly distributing heat due to the placement of burners at the bottom, leading to hotspots and difficulty in cleaning, as well as potential food contamination and inefficient air circulation.
Innovation Solution
A cooking appliance design featuring a partitioned cooking chamber with a burner assembly located at the rear, utilizing a fan to circulate heated air and a burner cover that defines a combustion chamber, allowing for improved air flow and heat distribution, while preventing food from contaminating the burner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the burner is placed at the bottom of the cooking chamber, then the structure is simple, but heat distribution is uneven causing hotspots
Solution Approach 1:
The burner is repositioned from the bottom (vertical dimension) to the rear wall (horizontal dimension), changing the spatial arrangement from bottom-up heating to rear-forward heating. This dimensional shift enables better heat distribution across the cooking chamber while maintaining structural simplicity.
2Ease of manufacture
If the burner is placed at the bottom of the cooking chamber, then installation is easy, but cleaning is difficult due to food contamination risk
Solution Approach 1:
The burner assembly is extracted from the bottom position and relocated to the rear wall, separating it from the food preparation area. This extraction eliminates the contamination risk while preserving installation simplicity, as the rear wall provides adequate access for maintenance and cleaning operations.
3Device complexity
If conventional air circulation is used without a fan, then the device is simpler, but heat distribution efficiency is poor
Solution Approach 1:
A fan is introduced to create forced air circulation within the cooking chamber, replacing passive convection with active pneumatic flow. This pneumatic system efficiently distributes heated air throughout the chamber, significantly improving heat distribution efficiency while adding only moderate complexity to the overall device.
