Title: HIGH-FREQUENCY HEATING DEVICE
Abstract:
This high-frequency heating device (1a) is provided with a generator (8), a surface wave exciter (10), a first coupler (12), and a reuse 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). The first coupler (12) is provided on one end (15) of the surface wave exciter (10). Microwaves generated by the generator (8) are supplied to the surface wave exciter (10) over the first coupler (12). The reuse unit (14) reuses the microwaves that have traveled from one end (15) of the surface wave exciter (10) and reached another end of the surface wave exciter (10) positioned in the propagation direction of the microwaves for heating of the object to be heated (6). This invention makes is possible to reuse microwaves that have not been absorbed by the object to be heated for heating of the object to be heated.
