Rear-Wall Gas Oven Burner Layout for Clean Combustion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Gas oven ranges face contamination and cleaning difficulties due to openings in the bottom surface that allow food and matter to flow into the burner chamber, leading to potential malfunctions and reduced cooking chamber capacity.
Innovation Solution
A burner assembly is installed on the rear wall of the cooking chamber, with a recessed bottom to increase capacity, featuring a plate with partitions to guide air and flames, and an air inlet to prevent incomplete burning, ensuring efficient heat transfer and minimizing contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If openings are provided in the bottom surface of the cooking chamber to transfer heated air, then heat transfer efficiency is improved, but food and matter can flow into the burner chamber causing contamination and malfunction
Solution Approach 1:
A cover member is introduced as an intermediary component between the cooking chamber and burner chamber. This cover member includes openings that allow heated air to pass through while preventing food and matter from entering the burner chamber, thus resolving the contradiction between heat transfer efficiency and contamination prevention
Solution Approach 2:
The cover member is segmented with multiple openings distributed across its surface, allowing selective passage of heated air while blocking contaminants. The partition within the cover member further segments the flow path to optimize heat transfer while maintaining contamination barriers
2Power
If a burner chamber is provided below the cooking chamber for convective heating, then heating efficiency is improved, but the cooking chamber capacity is reduced
Solution Approach 1:
The burner chamber is repositioned from a vertical arrangement below the cooking chamber to a horizontal arrangement at the rear wall. This dimensional change allows the cooking chamber to maintain its full vertical capacity while the burner operates efficiently in a separate spatial plane, resolving the contradiction between heating efficiency and cooking capacity
3Power
If the burner is installed below the cooking chamber, then convective heating is achieved, but cleaning difficulty increases due to contamination risk
Solution Approach 1:
The cover member acts as a protective intermediary that prevents food and matter from reaching the burner chamber during cooking and cleaning operations. This isolation makes the burner chamber accessible and easy to clean while maintaining its convective heating function
Solution Approach 2:
The burner assembly is extracted from its traditional below-chamber position and repositioned to the rear wall, separating it from the main cooking space. This extraction eliminates the contamination pathway that made cleaning difficult, while the burner retains its convective heating capability through the cover member openings

AI summary
A gas oven range may include a cavity forming a cooking chamber in which food may be cooked and a burner assembly installed on a rear wall of the cavity to heat the cavity. The burner assembly may include a burner having flame holes formed therein, a plate supporting the burner, and a cover covering the burner to form a burner chamber. An inlet may guide air from the cooking chamber into the burner chamber, and a partition may be provided between the cover and the plate to partition air flowing from the cooking chamber into the burner chamber from flames generated by the burner.
