MICROWAVE HEATING DEVICE

摘要

A microwave heating device of the present invention comprises a heating chamber housing an object to be heated, a microwave generation portion generating a microwave, a waveguide portion propagating the microwave, and a plurality of microwave radiating portions radiating the microwave in the heating chamber, wherein the microwave radiating portions are arranged in a direction orthogonal to a direction of electric field and to a direction of propagation within the waveguide portion, and centers of the microwave radiating portions are arranged at positions corresponding to approximate node positions of the electric field within the waveguide portion. The microwave heating device is enabled to make uniform heat distribution in the object to be heated, without using a driving mechanism.
