<p>PURPOSE:To make the wiring for a large current as short as possible and to suppress a voltage drop due to the wiring by providing a driving power source of a microwave generator near a battery. CONSTITUTION:A driving power source 7 of an electronic range main body 3 which is installed to operate in a cabin is composed of a DC-DC converter, and its output voltage can be raised to a voltage to allow a microwave generator 6 to carry out a desired operation. In consideration of earthing a heating chamber to the body of an automobile, the microwave generator is composed to be insulated from the heating chamber. This insulating structure is made with a waveguide 5 to connect the microwave generator and the heating chamber, and the waveguide 5 is composed of two members 5a and 5b. And since a driving power source 7 is arranged near a battery 2 provided in an engine room, a voltage drop due to the wiring can be restricted at a minimum, and the power utilizing efficiency of the power source can be maintained at a high level.</p> |
