Plate-shaped grill with full-surface cooking zone
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plate-shaped grills with induction or mass heating elements experience local temperature unevenness and delays in heating, leading to inconsistent grilling conditions across the grill surface, which affects the homogeneity of food grilling and flavor.
Innovation Solution
A plate-shaped grill design with a surface heating element that covers the entire underside of the grill plate, typically a sandwich structure with a resistance wire embedded in a mica fragment layer between aluminum plates, ensuring even and simultaneous heating across the entire surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If one or more induction or mass heating elements are used that act at specific points, then the heating structure is simple and energy consumption is reduced, but local temperature unevenness and heating delays occur
Solution Approach 1:
The heating element is divided into multiple independent heating zones (first heating element, second heating element, etc.) that can be independently controlled. Each heating element corresponds to a specific region of the grill plate, allowing localized heating control while maintaining overall temperature uniformity through coordinated operation of multiple segments.
2Temperature
If the entire underside of the grill plate is connected to surface heating elements, then temperature uniformity is improved, but device complexity and energy consumption increase
Solution Approach 1:
Different regions of the grill plate are equipped with heating elements according to their specific heating requirements. The heating elements are strategically positioned to address local temperature variations, ensuring each area receives appropriate heating intensity rather than uniform heating across the entire surface.
Solution Approach 2:
Instead of providing heating elements across the entire underside of the grill plate, heating elements are positioned only at critical locations where temperature control is most needed. This partial action approach achieves sufficient temperature uniformity while avoiding the complexity and energy consumption of full-surface heating elements.
3Reliability
If heating elements are positioned away from the edges, then safety is improved, but heating efficiency and speed decrease
Solution Approach 1:
The heating elements are arranged in a multi-dimensional configuration on the grill plate surface, utilizing both radial and axial dimensions. This spatial arrangement allows heating zones to extend toward the edges for improved heating efficiency while maintaining safe distances through proper positioning and spacing in different dimensional directions.
