摘要:
The problem to be solved by the invention is to restrain local heating peculiar to microwave heating to thereby realize the uniform heating of an object to be heated and thus enhance the condition of the object to be heated after heated. In a microwave heating method for supplying microwaves into a heating chamber 11 storing therein an object to be heated to heat the object to be heated, microwaves are supplied into the heating chamber 11 to heat the object to be heated; the temperature of the object to be heated is measured to check whether a given temperature difference has been generated in the temperature distribution of the object to be heated; and, when the given temperature difference has been generated, the minute particles of water are supplied into the heating chamber 11 to change the permittivity distribution state within the heating chamber 11, thereby changing the distribution of electric fields caused by the microwaves supplied into the heating chamber 11.

A compact and highly controllable impedance-varying-unit, a microwave device using the same unit, and a high-frequency-heating appliance using the same unit are provided. The impedance varying unit includes a rectangular waveguide-section as a main body made of metallic material, an open end of waveguide-section working on microwave in a microwave cavity, a terminal end of waveguide-section closed by metallic material, a rotary movable body made of non-metallic material, and a driver for the movable body. A rotating angle or a position of the movable body is controlled, so that an impedance at the open end is varied and transmission status of microwave is changed, thereby variably controlling a standing wave distribution. Controlling the standing wave distribution allows an object in the cavity to be selectively heated or uniformly heated. Further, the standing wave produced in the microwave cavity is sequentially varied, so that the object can be selectively heated or uniformly heated. The present invention solves the problem of spark production, and provides a compact as well as highly controllable impedance varying unit, a microwave device using the same unit and a high-frequency-heating appliance using the same unit.

In a microwave heating device of the present invention, a heating-chamber input portion is adapted to direct, to a heating chamber, microwaves having propagated through a waveguide tube and having passed through the positions where microwave radiating portions are formed, thereby realizing a state where progressive waves are dominant among the microwaves propagating through the waveguide tube, so that the microwave radiating portions are caused to radiate, to the inside of the heating chamber, microwaves based on the progressive waves propagating through the waveguide tube. This enables uniformly heating an object to be heated, without using a rotational mechanism.
