Gas Oven Reflector Layout for Efficient Combustion and Heat Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Gas oven ranges face inefficiencies in heat transfer and combustion efficiency, leading to incomplete combustion and potential harmful gas production.
Innovation Solution
A reflector is installed between the oven chamber ceiling and burner to reflect heat and flames towards food, while also creating a compartmentalized space for efficient combustion and exhaust of combustion gases, preventing leaks and incomplete combustion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a reflector is installed to reflect heat and flames toward food, then heat transfer efficiency is improved, but device complexity increases
Solution Approach 1:
The reflector is divided into multiple functional segments: a reflection surface for redirecting heat, a combustion chamber for controlled burning, and an exhaust channel for gas discharge. This segmentation allows each part to perform its specific function efficiently while maintaining overall system manageability and reducing complexity through functional specialization.
2Productivity
If the reflector compartmentalizes the oven chamber for efficient combustion, then combustion efficiency is improved, but the oven chamber volume available for food is reduced
Solution Approach 1:
The combustion chamber and exhaust channels are arranged in a three-dimensional configuration that utilizes vertical and lateral spaces above and around the food placement area. This spatial arrangement allows combustion processes to occur in dimensions that do not directly compete with food storage space, thereby maintaining both combustion efficiency and adequate oven volume.
3Loss of energy
If exhaust holes are provided in the reflector, then combustion gas discharge is improved, but heat retention efficiency deteriorates
Solution Approach 1:
The exhaust holes are strategically positioned and sized to provide localized gas discharge pathways in specific areas of the reflector. This localized approach allows combustion gases to be efficiently removed from critical zones while maintaining heat retention in food-facing areas, thus balancing heat retention efficiency with harmful gas discharge.

AI summary
A gas oven range and a reflector are provided. The gas oven range comprises an oven chamber in which food is cooked and an upper burner inside the oven chamber. The reflector reflects flame and heat and divides the oven chamber into a combustion space and an exhaust space. An exhaust hole is formed in the reflector to discharge combustion gas to the exhaust space, which is generated by combustion of gas at the burner in the combustion space. Therefore, incomplete combustion of gas is prevented, and leakage of flame and radiant heat generated by combustion of gas is prevented, thereby improving gas combustion efficiency.
