MICROWAVE OVEN WITH INDUCTION HEATING COOKER AND ITS CONTROL METHOD

摘要

The present invention relates to a microwave oven capable of induction heating, dielectric heating, induction heating and alternating heating and a control device thereof.;In the apparatus of the present invention, the induction heating coil is installed on the bottom of the cooking chamber, and the heat insulator is installed on the upper portion of the induction heating coil. The induction heating unit and the magnetron including the induction heating coil are provided. An induction / dielectric heating unit comprising a dielectric heating unit including; A high frequency power supply unit for supplying high frequency power to the induction / dielectric heating unit by intermitting a DC power source by rectifying an input AC power source; A switching control unit controlling an intermittent operation of the high frequency power supply unit; A door opening / closing detecting unit for detecting an open / closed state of the door; And a microprocessor for selectively connecting the DC power source to the induction heating unit or the dielectric heating unit according to the load sensing unit for detecting the material of the cooking vessel and the opening / closing state of the door and the material of the cooking vessel.
