Cooker Steam and Microwave Timing Control to Prevent Component Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Steam supplied into the cooking chamber may be discharged, leading to inefficient cooking and potential damage to the cooker components.
Innovation Solution
A method for controlling a cooker that oscillates microwave energy and generates steam, with the steam generator operating independently of the high-frequency heating source, and air circulation to prevent steam leakage through porous parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If steam is supplied into the cooking chamber before high-frequency heating starts, then cooking effectiveness is improved, but steam may be discharged leading to potential damage to cooker components
Solution Approach 1:
The control unit initiates steam generator operation at a preset time separately from when the high-frequency heating source starts, based on when the steam generation signal is input. This preliminary timing control ensures steam is available for effective cooking while preventing premature steam discharge that could damage components.
2Adaptability or versatility
If steam generator operates independently of high-frequency heating source, then cooking flexibility is improved, but control complexity increases
Solution Approach 1:
The control unit receives steam generation signals and automatically determines the operation start time of the steam generator based on preset timing rules. This feedback-based automatic control provides cooking flexibility while simplifying user operation despite the independent operation of multiple components.
3Manufacturing precision
If air circulation is operated during steam generation, then steam distribution is improved, but energy consumption increases
Solution Approach 1:
The convection part operates periodically during steam generation rather than continuously. The control unit manages the convection operation to coincide with steam generation phases, improving steam distribution uniformity while reducing unnecessary energy consumption during non-steam phases.

AI summary
A cooker controlling method is provided. The cooker controlling method includes oscillating microwave supplied to a cooking chamber, by a high-frequency heating source, and generating steam supplied to the cooking chamber, by a steam generator. In a case a signal for initiating the operation of the steam generator is input before the operation of the high-frequency heating source is started, the operation of the steam generator is initiated at a preset time separately of a time when the operation of the high-frequency heating source is started, and in a case a signal for initiating the operation of the steam generator is input after the operation of the high-frequency heating source is started, the operation of the steam generator is initiated at a time when the signal is input. Therefore, the food may be effectively and safely cooked using the steam.
