Gas Stove Burner Shell Structure for Heat Transfer and Drip Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Gas stoves lack a flame heat transfer regulating apparatus, leading to inefficient heating and the issue of dripping liquid substances burning on the cooktop, causing cleanliness problems.
Innovation Solution
A removable apparatus comprising an improved inner hollow shell and outer wall, designed to regulate flame heat transfer by reflecting radiated heat and directing convective heat, while also retaining dripping liquids with a circular valley structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a gas stove burner is used for cooking, then heating function is provided, but heating efficiency is low and combustible gas is wasted
Solution Approach 1:
The patent converts the harmful scattered radiated heat into beneficial heating by using the outer wall to reflect and redirect heat flow toward the cooking utensil. The outwardly radiated heat that would normally be wasted is now captured and redirected to heat the utensil and surrounding air, improving heating efficiency while reducing combustible gas consumption.
Solution Approach 2:
The patent changes the thermal parameters of the cooking environment by introducing a structured apparatus that modifies heat distribution patterns. The inner hollow shell and outer wall create controlled convection currents and redirect radiation, transforming the thermal field to concentrate heat where needed, thereby improving heating efficiency.
2Productivity
If a gas stove burner is used for cooking, then heating function is provided, but dripping liquid substances burn on the cooktop causing cleanliness problems
Solution Approach 1:
The patent introduces the inner hollow shell as an intermediary structure between the burner and the cooktop. This shell captures dripping liquid substances before they reach the cooktop surface, preventing burning and soiling. The intermediary structure allows the heating function to continue while blocking the harmful path of dripping liquids.
3Productivity
If flame heat transfer is not regulated, then simple burner structure is maintained, but heating efficiency is low
Solution Approach 1:
The patent segments the heat transfer regulation function into distinct components: the inner hollow shell for capturing and directing convective heat, and the outer wall for reflecting radiated heat. This segmentation allows each component to perform a specific heat regulation function, improving heating efficiency while maintaining a relatively simple overall structure that can be added to existing burners.
Solution Approach 2:
The apparatus performs multiple functions simultaneously: it regulates convective heat transfer through the inner hollow shell, reflects radiated heat through the outer wall, and prevents liquid dripping onto the cooktop. This multi-functionality improves heating efficiency without requiring multiple separate devices, thereby limiting the increase in device complexity.

AI summary
The removable apparatus includes an outer wall and improved inner hollow shell which are both positioned on the cooktop of a gas stove to surround an upper section of a burner, where the outer wall surrounds the hollow shell. The improved inner hollow shell is a closed preferably circular hollow member having a larger section connected to a smaller section thereby forming a valley of space to retain dripping liquid substance in cooking. A plurality of openings penetrate through the larger section, wherein more openings are located to its low part. The outer wall has multiple openings which evenly penetrate therethrough. Many extensions projecting upwardly are spaced apart onto a top edge of the outer wall to support a cooking utensil. The apparatus is served as a flame heat transfer regulator for achieving high heating efficiency in cooking and a liquid substance retainer for easily maintaining the cooktop clean.
