Integrated Venturi Gas Burner Assembly for Easier Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gas burner assemblies have complex production processes due to a high number of components or complex geometric structures, leading to high costs and difficulty in cleaning.
Innovation Solution
A simplified gas burner assembly comprising a burner cap, burner crown, and burner body, where the Venturi pipe is integrated within these components, reducing the number of parts and using a horizontal gap for air inlet, allowing for easier production and assembly, and featuring sloped flame ports for increased efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the gas burner assembly comprises a relative high number of components, then the production of the gas burner assembly is complex and causes high costs, but the functional requirements can be met
Solution Approach 1:
The patent merges multiple separate components into three integrated components: the Venturi pipe is combined with the burner crown and burner body, the holding element is integrated into the burner crown, and the connecting elements are incorporated into the component interfaces. This merging reduces the total component count while maintaining all necessary functions, directly resolving the contradiction between manufacturing ease and device complexity.
2Device complexity
If some single components have a complex geometric structure, then the number of components can be reduced, but it is not easy to clean such complex components
Solution Approach 1:
The patent combines the Venturi pipe functionality directly into the burner crown and burner body with smooth, continuous surfaces that do not create hidden corners or complex geometries. This merging approach maintains component simplicity for easy cleaning while achieving the desired reduction in total component count.

AI summary
The present invention relates to a gas burner assembly (10), in particular for a gas cooking hob, comprising a burner cap (12), a burner crown (14) and a burner body (16). The burner cap (12) is arranged or arrangeable upon the burner crown (14). The burner crown (14) is arranged or arrangeable upon the burner body (16). The gas burner assembly (10) comprises at least one elongated horizontal Venturi pipe (32, 34). An upper part (32) of the Venturi pipe is formed in a lower portion of the burner crown (14). A lower part (34) of the Venturi pipe (32) is formed in the burner body (16). At least one chamber (46, 52) is formed in an upper portion of the burner crown (14). The burner crown (14) includes at least one circumferential wall (22, 24) enclosing the at least one chamber (46, 52) and including a plurality of flame ports (26, 28). The burner crown (14) includes at least one passage opening (38) connecting an outlet of the Venturi pipe (32, 34) to the at least one chamber (46, 52). The Venturi pipe is formed by its upper part (32), its lower part (34) and the passage opening (38). A horizontal gap (60) is formed between the burner crown (14) and the burner body (16), wherein the horizontal gap (60) is provided as an inlet for primary air (56) and secondary air (58).
