Efficient Gas Burner Design for Cooking Appliances
Here’s PatSnap Eureka !
Summary
Problems
Existing gas burners for food cooking appliances face inefficiencies in directing flames towards the central portion of cooking containers, requiring multiple components and ad hoc solutions to prevent grates from becoming unbalanced, leading to increased costs and complexity.
Innovation solutions
A gas burner design featuring a vertically extending Venturi effect chamber within a flame divider with integrated appendices and a cap having elongated portions, which are tapered and coupled to form a pan supporting grate, allowing for efficient flame direction and reducing the need for additional components and balancing systems.

General conflict description:
Principle concept:
If the cap is laid on the flame divider with substantially circular design, then the air-gas mixture comes out substantially horizontally, but it becomes very difficult to direct the burner flames upwards towards the central portion of the bottom of cooking containers
Why choose this principle:
The flame divider is designed with asymmetric appendices extending in specific directions, and the cap has asymmetric elongated portions corresponding to these appendices. This asymmetric configuration guides the flames in specific directions towards the central portion of cooking containers, resolving the inability to direct flames upwards that existed with the symmetric circular design.
Principle concept:
If the cap is laid on the flame divider with substantially circular design, then the air-gas mixture comes out substantially horizontally, but it becomes very difficult to direct the burner flames upwards towards the central portion of the bottom of cooking containers
Why choose this principle:
The appendices and elongated portions add a dimensional element to the otherwise planar circular design. By extending these elements radially outward, the design creates three-dimensional flame guidance structures that direct flames vertically upward towards the cooking container center, transforming the two-dimensional horizontal flow into three-dimensional directed flow.

Abstract
The present invention relates to a gas burner (1;1'), in particular for a food cooking appliance, said burner (1, 1') comprising: – a cup (10; 10') comprising an injector (11, 11') for letting out gas coming from a duct (12, 12') that supplies gas to said burner (1, 1'); – a flame divider (20; 20') associated with said cup (10, 10') and comprising a Venturi effect chamber (21; 21'), in particular said chamber (21, 21') being positioned substantially coaxial to said injector (11, 11'); – a cap (30; 30') associated with said flame divider (20; 20') so as to allow gas to come out through a plurality of apertures (22; 22') of said flame divider (20; 20') and/or of said cap (30; 30'). The invention is characterized in that said flame divider (20; 20') is so designed as to comprise at least three appendices (23; 23') extending from a central portion (23C; 23C) of the flame divider (20; 20'), and said cap (30; 30') is so designed as to comprise at least three elongated portions (33; 33') coupled to said appendices (23; 23') and extending from a central area (33C; 33C) of said cap (30; 30'). The invention is further characterized in that said cap (30; 30') is integrated with a pan supporting grate (40; 40').
