PURPOSE:To restrain the generation of temperature grade as well as to enable the quick application of heat while enhancing productivity and quality as well by enabling microwave in a beam shape to continuously be reflected reciprocally between two reflectors, and thereby enabling microwave to convergently pass through a heated article. CONSTITUTION:When a microwave beam 2 injected out of an incident port 4 is reflected by the upper section of a reflecting surface 5, the beam is continuously reflected reciprocally between the reflecting surface 5 and a reflecting surface 6, this thereby causes the beam to convergently pass through the center section of a space between the reflecting surfaces 5 and 6, so that the intensity of the electromagnetic field at the center section is thereby increased by a factor of 5 through 10. This thereby causes a heated article 7 rested at the center section to be quickly heated by continuously reflecting wave because microwave convergently passes through the article. By this constitution, the heated article can be uniformly heated from its inside, the generation of temperature grade within the heated article can also be restrained, the article can concurrently be equally heated, and both productivity and quality can thereby be enhanced during heating processes. |
