Directional Ignition Electrode Structure for Precise Gas Range Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional gas stoves with piezo ignition electrodes suffer from inaccurate ignition due to flames extending in all directions, often resulting in prolonged or failed ignition.
Innovation Solution
An ignition electrode with a specially designed ┐-shaped structure featuring a groove on the ceramic jacket limits ignition direction, combined with a positioning collar and compression spring for secure attachment, ensuring precise ignition by directing the flame generation at the edge of the electrode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a traditional piezo ignition electrode is used, then the ignition system is simple and reliable, but the ignition accuracy is poor due to flames extending in all directions
Solution Approach 1:
The ignition electrode is segmented into multiple functional parts: a piezo element for generating sparks, a ceramic insulator for electrical isolation, and a directional flame guide structure. This segmentation allows each component to perform its specific function optimally, with the flame guide directing the flame in a controlled direction to improve ignition accuracy.
Solution Approach 2:
The ignition electrode employs an asymmetric design where the ceramic insulator has a specific geometric shape with a flat side and a curved side. This asymmetric configuration, combined with the directional flame guide, ensures that the flame is directed towards the burner in a specific direction rather than extending uniformly in all directions, thereby improving ignition accuracy.
2Reliability
If the ignition electrode structure is simplified, then manufacturing is easier, but ignition reliability decreases due to prolonged or failed ignition
Solution Approach 1:
The ignition electrode combines multiple functions into a single integrated component: the piezo element, ceramic insulator, and directional flame guide are assembled together as one unit. This merging ensures that all necessary functions (spark generation, electrical isolation, and flame direction) are present in a compact structure, improving ignition reliability without requiring multiple separate components.
Solution Approach 2:
The ignition electrode is pre-assembled with the directional flame guide structure already in place during manufacturing. This preliminary configuration ensures that the flame will be directed correctly from the moment of ignition, eliminating the need for additional adjustment or alignment steps that would complicate manufacturing while ensuring reliable ignition performance.

AI summary
The present invention relates to an ignition electrode for gas stoves and a gas stove with such an ignition electrode. Accordingly, an ignition electrode (1, 1) is proposed, which comprises an electrode (3, 3) and a ceramic jacket (2, 2) surrounding it from the outside and is characterized in that on the upper side of the ceramic jacket (2, 2 ) a structure for limiting the ignition direction (4, 23) of the electrode (3, 3) is formed. With an ignition electrode designed in this way, ignition can be carried out at a desired point in a desired direction, as a result of which ignition can be carried out more precisely and more effectively.
