Upper-Intake Stove Burner with Segmented Airflow for Heat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing household stove burners with upper intake air and super-high power suffer from poor heat dissipation performance, leading to increased load and significant load reduction gradients over time.
Innovation Solution
The stove burner design includes a central and outer ring air intake system with specific diameter variations, slow flow and steady flow plates, and flame stabilizing features to improve heat dissipation, featuring a small semicircular outer ring pre-mixing cavity and gaps between air intake tubes to enhance air flow management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a conventional household stove burner with upper intake air is used, then it can achieve basic cooking function, but the heat dissipation performance is poor resulting in increased load and great load reduction gradient
Solution Approach 1:
The air intake system is segmented into multiple independent channels: central fire air intake tube, outer ring air intake tubes (left and right), and primary air intake cavity. Each channel has specific diameter variations (inner screw cavity diameter greater than light tube portion diameter) to optimize airflow distribution and heat dissipation independently, resolving the contradiction between energy loss and load stability
Solution Approach 2:
Different parts of the air intake system have different structural characteristics: the central fire air intake tube has a central inner screw cavity with specific diameter ratio to light tube portion, the outer ring air intake tubes have left and right inner screw cavities with similar diameter ratios, and the primary air intake cavity has central, left, and right air intake portions. These local structural variations optimize heat dissipation in different zones while maintaining overall load stability
2Stability of the object's composition
If the outer ring pre-mixing cavity is made small semicircular with slow flow and steady flow plate, then the airflow becomes more controlled, but the device complexity increases
Solution Approach 1:
The slow flow and steady flow plate is pre-installed in the outer ring pre-mixing cavity to regulate airflow characteristics before the air-fuel mixture reaches the combustion zone. This preliminary airflow control ensures stable combustion without requiring complex real-time adjustment mechanisms, achieving airflow stability while limiting complexity increase
Solution Approach 2:
The outer ring pre-mixing cavity is designed with a specific small semicircular geometry and the slow flow and steady flow plate modifies flow parameters (velocity, direction) to achieve controlled airflow. This geometric parameter optimization provides airflow stability without adding excessive structural complexity

AI summary
A household stove burner with upper intake air and super-high power includes a cup body, a distributor base, a central distributor, an outer ring distributor, an ignition needle and an induction needle. The household stove burner further includes an air intake base, a central air intake tube, a left air intake tube and a right air intake tube, and a gap is between the central air intake tube and a light tube portion of the central fire air intake tube. A gap is between the left air intake tube and the light tube portion of the left outer ring air intake tube, a gap is between the right air intake tube and the light tube portion of the right outer ring air intake tube, a lower end of an air intake cavity of the distributor base is docked with an outer ring pre-mixing cavity, an outer interface of the outer ring distributor is inserted into an outer ring fuel gas tank, and an inner ring wall plate of the outer ring fuel gas tank is inserted into the outer ring distributor. An outer ring flame stabilizing slot and a flame stabilizing plate are arranged on the outer ring distributor to prevent the generation of the outer ring firm flame. The central air intake tube and the light tube portion of the central fire air intake tube are arranged at intervals, the left air intake tube and the light tube portion of the left outer ring air intake tube are arranged at intervals, and the right air intake tube and the light tube portion of the right outer ring air intake tube are arranged at intervals, so that the heat dissipation performance is improved.
