Title: HIGH-FREQUENCY HEATING DEVICE
Abstract:
This high-frequency heating device (1A) is provided with a generator (8), a surface wave exciter (10), couplers (12a, 12b), and a phase change unit (14). The generator (8) generates microwaves. The surface wave exciter (10) has a periodic structure and propagates microwaves in a surface wave mode to heat an object to be heated (6). Multiple microwaves are supplied to the surface wave exciter (10) over the multiple couplers (12a, 12b) provided at the end of the surface wave exciter (10). The phase change unit (14) changes the phase difference between the multiple microwaves. With this invention, by changing the orientation of the electric field distribution (20) formed on the surface wave exciter (10), it is possible to control the position of the heating region and the degree of heating in the heating region.
