Title: HIGH-FREQUENCY HEATING DEVICE
Abstract:
This high-frequency heating device (1a) is provided with a first generator (8), a surface wave exciter (9), and a first coupler (12). The first generator (8) generates microwaves. The surface wave exciter (9) has multiple metal plates (11) arranged periodically at a prescribed interval in the propagation direction of the microwaves, and propagates microwaves in a surface wave mode to heat an object to be heated (6). The first coupler (12) is provided in an intermediate portion of the surface wave exciter (9) in the propagation direction (D) of the microwaves such that microwaves generated by the first generator (8) are supplied over the first coupler (12) to the surface wave exciter (9). This invention makes it possible to more uniformly heat an object to be heated.
