Claims (1)

[Scope of claim for utility model registration] (1) A high-frequency heating cooker in which high-frequency radio waves generated by a high-frequency oscillation power source are introduced into the heating chamber through a power supply opening provided in the ceiling wall of the heating chamber through a waveguide. A hemispherical dielectric body facing the power supply opening is bulged integrally with the waveguide on the ceiling surface of the waveguide at a position directly above the power supply opening formed in the ceiling wall of the heating chamber. A high-frequency heating cooker characterized by: (2) The height of the bulge of the hemispherical dielectric body, which is bulged out integrally with the ceiling surface inside the waveguide facing the power supply opening opened in the ceiling wall of the heating chamber, is one-half of the total height of the waveguide. A high-frequency heating cooker according to claim 1 of the utility model registration claim, characterized in that: (3) The scope of claim 1 for registration of a utility model, characterized in that the diameter of the hemispherical dielectric body integrally bulging on the ceiling surface inside the waveguide is one-half of the total height of the waveguide, or The high-frequency heating cooker according to any one of Item 2.
