| 主权项 | 1. A high-frequency heating apparatus, comprising: a heating chamber to which a heating plate for loading a subject to be heated thereon is detachably attached; a microwave generating unit; a waveguide for transmitting a microwave from the microwave generating unit; a rotation antenna for radiating the microwave into the heating chamber from the waveguide; a driving unit for rotating the rotation antenna; an operating portion capable of choosing a grill menu by which the subject to be heated put on the heating plate is heated and a hot-up menu by which the subject to be heated is heated without the heating plate; and a controlling unit for controlling the driving unit based on an output signal from the operating portion; wherein the controlling unit controls the driving unit to vary a direction of a sharp portion of a radiation directivity of the rotation antenna in response to the output signal from the operating portion, wherein the controlling unit controls the driving unit to rotate the rotation antenna to a predetermined rotation position and to oscillate the rotation antenna within a predetermined degree of the rotation of the rotation antenna around the predetermined rotation position. | ||
