Solution Overview
Problem
The high-frequency heating cooking system described in JP H10-160166 A often results in insufficient heating of food due to power-saving measures during microwave heating, which can lead to incomplete cooking.
Innovation Solution
A heating cooking apparatus and method that includes a microwave supply unit, an image capturing unit, and a communication unit, where the controller reduces the intensity of microwaves during image transmission to prevent interference and then increases the intensity or supply time after transmission to ensure thorough heating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the intensity of microwaves is reduced during communication to prevent radio wave interference, then communication stability is improved, but heating effectiveness deteriorates
Solution Approach 1:
The microwave supply unit operates in periodic cycles, alternating between normal heating mode and reduced-power communication mode. The controller temporarily reduces microwave intensity only during image transmission periods, then restores full power afterward, achieving both stable communication and effective heating through time-based periodic operation
Solution Approach 2:
The controller predicts the total amount of energy required for heating before communication occurs. Based on this prediction, it pre-calculates and determines the appropriate extended heating time in advance, so that when communication interrupts heating, the system can compensate by extending duration rather than reducing power, ensuring complete heating is achieved
2Power
If the intensity of microwaves is maintained at high level during communication, then heating effectiveness is improved, but radio wave interference increases
Solution Approach 1:
The system uses periodic action by temporarily suspending high-power microwave operation during communication intervals. The controller synchronizes microwave supply with communication timing, reducing power only when image transmission occurs, thereby eliminating radio wave interference while minimizing impact on overall heating effectiveness through the periodic resume of full power
3Reliability
If the cooking time is extended to compensate for power reduction during communication, then heating completeness is improved, but productivity deteriorates
Solution Approach 1:
The controller performs preliminary calculation of the total energy required for complete heating before communication interrupts the process. Based on this advance prediction, it determines the precise extension time needed and implements it efficiently after communication, minimizing the overall time penalty while ensuring heating completeness is achieved

AI summary
A heating cooking apparatus includes a microwave supply unit, an image capturing unit, a communication unit, and a controller. The microwave supply unit supplies microwaves to an object to be heated and heats the object to be heated. The image capturing unit captures an image of the object to be heated. The communication unit transmits an image capturing result generated by the image capturing unit to a server. The controller controls the microwave supply unit such that an intensity of microwaves is reduced to be less than an intensity of microwaves before the communication unit transmits the image capturing result while the communication unit transmits the image capturing result to the server. After the communication unit transmits the image capturing result, the controller controls the microwave supply unit such that at least one of an intensity of microwaves or a supply time period of the microwaves is increased.
