    • A utensil for supporting microwave heatable material in a microwave oven is provided with a microwave responsive illuminator including a light source connected to a suitable antenna for receiving microwave energy and directing it to the light source. The oven has an energy distributor disposed for varying localized field intensities of microwave energy in the oven to promote uniform cooking of the heatable material. When the localized field intensity of the microwave energy adjacent the antenna rises periodically above a predetermined value, the antenna receives sufficient energy to cause illumination of the light source. When the localized field intensity falls below the predetermined value, the antenna receives insufficient energy for maintaining the illumination and the light source is extinguished. Thus, the energy distributor, in addition to promoting uniform cooking of the heatable material, also causes intermittent illumination or flashing of the light source to enhance attractiveness of the utensil. Further, the use of an antenna to receive varying amounts of microwave energy from the oven eliminates the requirement for sophisticated auxiliary circuitry to produce intermittent illumination or flashing of the light source.
    • 用于在微波炉中支持微波可加热材料的器具设置有微波响应照明器,其包括连接到用于接收微波能量并将其引导到光源的合适天线的光源。 烘箱具有能量分配器,其设置用于在烤箱中改变微波能量的局部场强,以促进可加热材料的均匀蒸煮。 当邻近天线的微波能量的局域化强度周期性地超过预定值时,天线接收足够的能量以引起光源的照明。 当局部场强降低到预定值以下时,天线接收不足以维持照明的能量,光源熄灭。 因此,除了促进可加热材料的均匀烹调之外,能量分配器还导致光源的间歇照明或闪光,以增强器具的吸引力。 此外,使用天线从烤箱接收不同量的微波能量消除了对复杂辅助电路产生间歇照明或光源闪烁的要求。

    • A microwave heating appliance having a metallic member supporting a body comprising ferrite bonded to an outer surface of the metallic member with a grooved inner surface of the metallic member contacting a food body to be heated by thermal energy generated from microwave energy absorbed by the ferrite body and transferred through the metallic member to the food body. An additional metallic member forms a container for the food body, and adjacent peripheral areas of the two metallic members provide substantial microwave sealing between the two metallic members thereby substantially shielding the food body from the microwave energy when the appliance is placed in a microwave oven. Upper and lower surfaces of the interior of the appliance contain grooves to form corrugated surfaces which contact the food body and which permit juices produced by heating the food body to flow away from regions of contact between the corrugated surfaces and the food body.
    • 一种微波加热器具,其具有金属构件,所述金属构件包括铁氧体,所述金属构件与所述金属构件的外表面接合,所述金属构件的带槽的内表面与要被加热的食品体接触,所述热能由由所述铁氧体本体吸收的微波能量产生的热能 并通过金属构件转移到食物体上。 附加的金属构件形成用于食物体的容器,并且两个金属构件的相邻周边区域在两个金属构件之间提供实质的微波密封,从而当将器具放置在微波炉中时基本上屏蔽食物与微波能量。 器具内部的上表面和下表面包含凹槽以形成与食物体接触的波纹表面,并且允许通过加热食物体而产生的果汁从波纹表面与食物体之间的接触区域流出。
