| (54) | Microwave oven with induction heating function |
| (57) An improved microwave oven with an induction heating function capable of selectively
using a microwave oven or an induction heat function without any interruptions from
a microwave oven heating circuit and an induction heating circuit when cooking food,
which includes a microcomputer for generating a cooking mode selection control signal
and a pulse width modulation signal in accordance with a cooking mode selection key
input and for controlling a selection operation of the microwave heating circuit and
the induction heating circuit; a relay drive circuit for generating a first drive
signal and a second drive signal in accordance with a cooking mode selection control
signal outputted from the microcomputer and for outputting a certain drive signal;
and first and second relays, selectively switched by the first drive signal or the
second drive signal outputted from the relay drive circuit, for supplying an electric
voltage of a power supply circuit to the microwave heating circuit and the induction
heating circuit. |
