平２−６８８８５号公報参照)。2. Description of the Related Art In general, in a high-frequency heating apparatus such as a microwave oven, a high-frequency oscillator such as a magnetron is provided on one of side walls of a box-shaped housing forming a heating chamber, and cooking on a turntable in the heating chamber is performed through a power supply port. It is configured to absorb and heat an object by irradiating it with an electromagnetic wave (for example, see Japanese Patent Application Laid-Open No. 2-68885).

ている。However, in the above-described conventional high-frequency heating apparatus, the cooking object is irradiated because the power supply port of the high-frequency oscillator is located only on a part of one side of the heating chamber housing. There is a problem that the electromagnetic waves are not always uniformly absorbed by the cooked food, causing uneven heating. As a result, for example, inconvenience such as not being able to properly thaw frozen food is caused.

大幅にアップする難点がある。[0004] For this reason, for example, the above-mentioned uneven heating can be prevented by rotating the food at a constant speed by the turntable, or by positively reflecting and diffusing an electromagnetic wave by providing a separate stirrer fan or the like. Although an improved configuration is adopted, it is not possible to sufficiently eliminate uneven heating by simply rotating the food with a turntable, and there is a problem that if a stirrer fan is separately provided, the product cost will increase significantly. .
