Burner Cover Flow Guide for Food-Contamination Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional oven ranges have design flaws that allow food leftovers to contaminate the burner chamber, making cleaning difficult and reducing cavity capacity due to the installation of the lower burner under the oven chamber.
Innovation Solution
A cooking device design featuring a burner cover with an air inlet hole and a flow guide that changes the air flow direction, allowing for a combustion chamber separate from the oven chamber, preventing contamination and facilitating cleaning while maximizing cavity capacity by relocating the burner assembly to the rear wall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the burner chamber is provided under the oven chamber to enable convective heating, then heating efficiency is improved, but food leftovers can enter the burner chamber through the open bottom surface causing contamination
Solution Approach 1:
The patent divides the heating system into separate combustion chamber and oven chamber, with the combustion chamber positioned at the rear wall rather than under the oven chamber. This segmentation prevents food leftovers from falling into the combustion chamber while maintaining convective heating capability through dedicated air inlet holes and flow guides.
Solution Approach 2:
The patent introduces a burner cover with flow guides as an intermediary structure that directs air flow from the air inlet holes toward the ignition unit. This mediator ensures proper mixing of air and gas while preventing direct exposure of the combustion chamber to food particles in the oven chamber.
2Power
If the burner is installed under the oven chamber, then convective heating is achieved, but cleaning becomes difficult due to the open bottom surface
Solution Approach 1:
By relocating the combustion chamber to the rear wall and separating it from the oven chamber, the patent creates a closed structure that can be easily removed and cleaned. The burner cover and flow guides are designed as separate components that facilitate maintenance while preserving convective heating function through controlled air flow paths.
3Power
If the lower burner is installed under the oven chamber, then heating function is provided, but cavity capacity is reduced by the burner installation space
Solution Approach 1:
The patent relocates the combustion chamber from the vertical space under the oven chamber to the horizontal rear wall position. This dimensional change allows the oven chamber to utilize the full vertical height for food storage, maximizing cavity capacity while the combustion chamber occupies the rear wall space for heating operations.
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
Prevents food leftovers from entering the burner chamber, enhances cleaning efficiency, and increases the cooking device's cavity capacity by relocating the burner assembly, ensuring effective and efficient cooking operations.
Implementation Method 1
a flow guide provided in the burner cover and configured to be operated by a flow resistance of air flowing a space between the ignition unit and the burner
Implementation Method 2
a burner which cooks the food in the oven chamber by burning a gas

AI summary
A cooking device includes a frame to form a cooking chamber; a burner cover disposed inside the frame and to form a combustion chamber and have an air inlet hole in which air is introduced; a burner in the combustion chamber; an ignition device in the combustion chamber and to have an ignition unit for igniting a mixed gas discharged from the burner; and a flow guide to change a flow direction of the air which is introduced through the air inlet hole at a side of the ignition unit, wherein the flow guide is formed as a portion of the burner cover protrudes to the combustion chamber by forming.
