Steam Cooker Timing Control for Chamber Steam Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Steam supplied into the cooking chamber of steam cookers often leaks out, leading to inefficient cooking and potential damage to the cooker components.
Innovation Solution
A method for controlling a cooker that generates radiant heat and convection heat, with a steam generator operating independently of the heating source, ensuring steam is supplied effectively and safely into the cooking chamber by preset timing controls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the steam generator operates independently with preset timing control, then steam is supplied effectively into the cooking chamber, but the control system complexity increases
Solution Approach 1:
The steam generator operates independently with preset timing control, generating and supplying steam into the cooking chamber before the heating source starts heating. This preliminary action ensures that steam is already present in the cooking chamber when heating begins, improving cooking efficiency and food quality without requiring complex real-time coordination between steam generation and heating operations
2Productivity
If steam is supplied into the cooking chamber, then cooking effectiveness is improved, but steam leaks out causing energy loss
Solution Approach 1:
The patent acknowledges that steam may leak out of the cooking chamber but converts this potential harm into a benefit by continuously generating steam independently of the heating cycle. The independent preset timing control ensures that steam is replenished at optimal moments, transforming the energy loss from leaking steam into an opportunity to maintain steam presence in the chamber more effectively
3Loss of time
If the steam generator starts before the heating source, then steam is established in the chamber earlier, but the operational timing control becomes more complex
Solution Approach 1:
The steam generator is configured to start at preset time points before the heating source begins operation. This preliminary action establishes steam in the cooking chamber earlier, reducing the time needed for steam cooking to become effective. The preset timing control simplifies the coordination by using predetermined schedules rather than complex real-time adjustments

AI summary
A method for controlling a cooker is provided. The method for controlling the cooker includes generating radiant heat and convection heat supplied into a cooking chamber by a heating source and operating a steam generator to generate steam supplied into the cooking chamber. When a signal for starting an operation of the steam generator is input before an operation of the heating source starts, the operation of the steam generator starts at a preset time point regardless of a time point at which the operation of the heating source starts. Also, when a signal for starting an operation of the steam generator is input after an operation of the heating source starts, the operation of the steam generator starts at a time point at which the signal is input. Thus, the food may be effectively and safely cooked using the steam.
