PROBLEM TO BE SOLVED: To provide a heating cooker that can utilize both a heating method having high energy saving performance for concentrically heating a heating target, and a heating method having uniform heating performance for uniformly heating the overall heating target, and easily switch both the methods with each other.SOLUTION: A heating cooker comprises a heating chamber in which food is accommodated, microwave generating means for generating microwaves to be supplied to the heating chamber, and a waveguide which is provided outside the heating chamber so as to communicate with the heating chamber. The microwave generation means comprises a semiconductor element capable of setting a phase and an oscillation frequency. Output terminals of the plural microwave generation means are connected to the waveguide. The microwaves generated by the microwave generation means are combined in the waveguide and then supplied into the heating chamber.SELECTED DRAWING: Figure 1 |
