Gas Burner Nozzle Layout for Lower Profile and Easier Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas burners have a heightened top burner part due to the need for a space to install the nozzle and allow gas to flow upwards, increasing the overall height and complicating the cleaning process, which exposes the upper plate to external elements and makes it difficult to maintain cleanliness.
Innovation Solution
The design incorporates a nozzle installation part that protrudes through a hole in the upper plate, allowing the nozzle to be positioned above the plate, reducing the internal height of the burner body and using supporting parts with reduced horizontal cross-sectional areas for easier cleaning, while preventing foreign substances from entering the burner assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the nozzle is installed inside the burner body below the upper plate, then the gas can flow upward through the burner body, but the longitudinal height of the burner body must be increased to accommodate the nozzle installation space and gas flow path
Solution Approach 1:
The nozzle is inverted from its conventional position inside the burner body to protrude upward through the upper plate. This inversion eliminates the need for internal nozzle installation space and upward gas flow path within the burner body, thereby reducing the longitudinal height of the burner body while maintaining functional integrity
2Ease of operation
If the burner head is separated from the burner body for cleaning, then the burner head and cap can be cleaned, but the hole in the upper plate is exposed to the outside making it difficult to clean the upper plate and allowing water or foreign substances to enter
Solution Approach 1:
The nozzle serves as an intermediary element that protrudes through the upper plate, creating a sealed interface between the burner interior and exterior. This intermediary structure allows the upper plate to be cleaned without exposing internal components to foreign substances, as the nozzle itself can be removed and cleaned separately while maintaining the sealing function
3Length of moving object
If the nozzle installation part protrudes through the upper plate, then the internal height of the burner body is reduced, but the supporting parts must have reduced horizontal cross-sectional areas to facilitate cleaning
Solution Approach 1:
The supporting parts are designed with non-uniform cross-sectional areas, featuring reduced horizontal dimensions in regions that require cleaning access. This local quality modification allows the supporting parts to maintain structural function while facilitating easier cleaning, as the reduced cross-sectional areas create smoother surfaces and fewer crevices where debris can accumulate
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 configuration minimizes the overall height of the gas burner, enhances the cleanability of the upper plate, and prevents the introduction of substances into the burner, thereby maintaining cleanliness and reducing the height of the cooking appliance.
Implementation Method 1
A nozzle 154 is horizontally installed at the nozzle installation part 152, and an injection hole 155 through which the gas is injected is formed at a lower side of the nozzle 154 in a direction perpendicular to a gas injection direction
Implementation Method 2
A guide part 134 which guides the mixed gas flowing part 132 to flow along an upward direction toward the burner cap 140 may be provided at the burner head 130
Implementation Method 3
a burner in which a gas is burnt to cook the food in the oven chamber
