ELECTROMAGNETIC CHAMBER ELEMENT COOLING STRUCTURE OF MICROWAVE OVEN COMPRISING HOOD

摘要

PURPOSE: A cooling efficiency of electromagnetic chamber elements are maximized to improve reliability of the electromagnetic chamber elements and to reduce manufacturing cost. CONSTITUTION: A vent motor assembly(40) is installed in upper part of a cavity(20) to form air flow for hood function and heat discharging of an electromagnetic chamber element. An intake air grill(50) intakes outer air to upper part of the cavity by a suction force of the vent motor assembly. Electromagnetic chamber elements are installed in an air flow passage through the upper part of the cavity.
