Rear-Wall Burner Layout for Uniform Cooking and Cleaner Ovens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cooking appliances face challenges in air circulation and heat distribution due to the placement of burners at the bottom, leading to inefficient cooking and difficulty in cleaning, as well as potential food residue issues from burner placement.
Innovation Solution
The cooking appliance design includes a burner assembly positioned at the rear wall of the cavity, with a partition plate and fan system that enhances air circulation and heat distribution by creating a separate combustion chamber and exhaust passage, preventing the burner from contacting food residue and improving cooking efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the burner is placed at the bottom of the cooking chamber, then the structure is simple, but the heat distribution is inefficient and cleaning is difficult
Solution Approach 1:
The burner is repositioned from the bottom surface to the rear wall of the cooking chamber, changing its spatial location to enable better heat distribution patterns and improve cooking efficiency while maintaining structural simplicity
2Ease of manufacture
If the burner is placed at the bottom of the cooking chamber, then the structure is simple, but food residue contamination occurs
Solution Approach 1:
The burner is extracted from its conventional bottom position and relocated to the rear wall, separating it from the area where food residue accumulates, thereby eliminating contamination risk while preserving structural simplicity
3Productivity
If a fan system is added to improve air circulation, then heat distribution is enhanced, but device complexity increases
Solution Approach 1:
The fan system is configured to utilize the existing burner placement and chamber geometry to generate beneficial air circulation patterns, allowing the system to self-regulate heat distribution without requiring complex control mechanisms or additional components
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 enhances air circulation and heat distribution, ensuring more uniform cooking and reducing the risk of food residue contamination, while simplifying cleaning by eliminating direct contact between the burner and the bottom of the appliance.
Implementation Method 1
a fan to allow the air within cooking chamber to flow, the fan to discharge the air within the burner cover through the opening of the burner cover
Implementation Method 2
a burner disposed within the cooking chamber to generate flame for supplying heat to the cooking chamber
