Title:
MEAL SERVING WAGON, MEAL SERVING WAGON OF ELECTROMAGNETIC INDUCTION HEATING, AND DISHES
Document Type and Number:
Japanese Patent JP2002355129
Kind Code:
A
Abstract:
To provide a meal serving wagon of electromagnetic induction heating, which can generate stable heating by setting a correcting means to a change in power voltage of commercial AC power.
Dishes are heated by electromagnetic induction heating using an inverter, which comprises a resonant circuit which drives coils of electromagnetic induction heating connected in parallel to resonate with a resonant condenser, a switching transistor which adjusts input to the load of the resonant circuit, and a control device which outputs gate signals to the switching transistor in order to correct and regulate the change of input to the load of the resonant circuit according to a change in source voltage.
