Abstract Reducing the sensitivity of microwave oven heating and cooking performance to load volume, load placement and load properties has been a long-standing challenge for microwave and microwave-convection oven designers. Conventional design problem and solution methods are reviewed to provide greater insight into the challenge and optimum operation of a microwave oven after which a new strategy is introduced. In this methodology, a special load isolating and energy modulating device called a transducer-exciter is used containing an iris, a launch box, a phase, amplitude and frequency modulator and a coupling plate designed to provide spatially distributed coupling to the oven. This system, when applied to a combined microwave-convection oven, gives astounding performance improvements to all kinds of baked and roasted foods including sensitive items such as cakes and pastries, with the only compromise being a reasonable reduction in the maximum available microwave power. Large and small metal utensils can be used in the oven with minimal or no performance penalty on energy uniformity and cooking results. Cooking times are greatly reduced from those in conventional ovens while maintaining excellent cooking performance.

组合微波炉：创新设计策略

摘要 降低微波炉加热和烹饪性能对负载体积、负载放置和负载特性的敏感性一直是微波和微波对流烤箱设计人员面临的长期挑战。回顾传统的设计问题和解决方法，以更深入地了解微波炉的挑战和最佳操作，然后引入新的策略。在该方法中，使用称为换能器激励器的特殊负载隔离和能量调制设备，其中包含一个光圈、一个发射箱、一个相位、幅度和频率调制器以及一个耦合板，旨在为烤箱提供空间分布的耦合。该系统应用于组合式微波对流烤箱时，为各种烘焙和烘焙食品提供惊人的性能改进，包括蛋糕和糕点等敏感食品，唯一的妥协是合理降低最大可用微波功率。可以在烤箱中使用大小金属器皿，对能量均匀性和烹饪结果的性能损失很小或没有。与传统烤箱相比，烹饪时间大大减少，同时保持出色的烹饪性能。
