Induction Hob Dual-Temperature Control for Food Core
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current induction cooking appliances lack precise control over both the cooking medium temperature and the inner temperature of the food, leading to inconsistent cooking results, especially for certain types of food that require specific temperature control.
Innovation Solution
A cooking appliance and method that allows automatic regulation of heat power based on two temperature values: one for the cooking medium and another for the central area of the food, using temperature probes and a control unit to ensure the food reaches the optimal cooking temperature, regardless of the cooking medium or food thickness, with user interface programming options for various cooking techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If temperature control is based only on cooking vessel or cooking medium temperature, then the control system is simple, but the food inner temperature cannot reach the optimum point for consumption
Solution Approach 1:
The patent divides the temperature measurement function into two separate sensors: one for measuring the cooking medium temperature and another for measuring the food inner temperature. This segmentation allows independent monitoring of both temperatures, enabling precise control of food cooking while maintaining a relatively simple overall system structure.
Solution Approach 2:
The patent introduces a microcontroller as an intermediary that receives temperature data from both sensors and automatically adjusts the heating power accordingly. This intermediary component coordinates the control logic, eliminating the need for complex manual control while achieving precise food temperature regulation.
2Reliability
If manual temperature adjustment is used, then the device structure is simple, but stable and accurate cooking process cannot be guaranteed
Solution Approach 1:
The patent implements a closed-loop feedback system where temperature sensors continuously monitor both the cooking medium and food inner temperatures, and the microcontroller automatically adjusts the heating power based on this feedback. This ensures stable and accurate cooking process while maintaining simple device structure through automated control logic.
3Manufacturing precision
If cooking time is extended at lower temperatures, then food properties are better preserved, but cooking time increases
Solution Approach 1:
The patent employs dynamic temperature control that automatically adjusts heating power based on real-time temperature measurements. The system can operate at lower temperatures for extended periods to preserve food quality, or increase temperature when needed to reduce cooking time, providing flexible adaptation to different cooking requirements.
