摘要： A microwave oven includes a cavity in which food is accommodated, a magnetron for generating microwaves, and a waveguide to supply microwaves generated from the magnetron into the cavity. The waveguide has substantially a truncated cone configuration in which the cross sectional area at the cavity side is greater than the cross sectional area at the magnetron side, and an output antenna of the magnetron is disposed to project from the bottom of the waveguide at the magnetron side into the inner space of the waveguide. The microwave oven further includes a flat radiation antenna fixed in the inner space of the waveguide around the output antenna of the magnetron while maintaining distances from the waveguide and the output antenna of the magnetron in which no spark is generated. Therefore, the radiation area for emitting the microwaves is increased significantly to improve heating nonuniformity within the cavity.
摘要翻译：微波炉包括容纳食物的空腔，用于产生微波的磁控管，以及将从磁控管产生的微波提供到空腔中的波导。波导具有基本上截头圆锥形构造，其中空腔侧的横截面面积大于磁控管侧的横截面面积，并且磁控管的输出天线设置为从磁控管的波导底部突出一侧进入波导的内部空间。微波炉还包括固定在波导的内部空间中的扁平辐射天线，围绕磁控管的输出天线，同时保持距离波导和不产生火花的磁控管的输出天线的距离。因此，用于发射微波的辐射面积显着增加以改善腔内的加热不均匀性。

摘要： The present invention relates to a microwave heating device, and in particular, a microwave heating device with a microwave heating element mounted on the surface of a heating dish on which food is placed inside a heating chamber. The microwave heating device according to the present invention includes a heating chamber for placing an object to be heated; a magnetron for generating microwaves; a waveguide for supplying the microwaves generated by the magnetron through the bottom of the heating chamber; a heating dish on which the object to be heated is placed; a microwave heating element positioned on the bottom surface of the heating dish to generate heat by absorbing microwaves; and an access passage for allowing the microwaves supplied by the waveguide to reach above the heating dish from below the heating dish. The object on the heating dish is heated by the heating dish, which is heated by the microwave heating element and by microwaves that reach above the heating dish. Therefore, the surface and the inside of the object can be heated in a simple and quick heating operation.
