摘要

The apparatus has heating units for heating food stored in a cooking chamber of the apparatus. One of the heating units is mounted in series with the other two heating units, where the second and third latter heating units are mounted in parallel. Cutting units (C, D, E, F) i.e. switch, are mounted respectively in series with the second and third latter heating units. A grid resistor (13) and a transformer are mounted in parallel, where an electric resistor is mounted at proximity of the grid resistor.
