Abstract: PURPOSE: A power coupling unit structure of a microwave oven as a hood is provided to use a power cord for only the microwave oven in case of separating the power cord from the microwave oven. CONSTITUTION: A microwave oven as a hood consists of an inlet socket molded in one side of the microwave oven; a power cord plug inserted into the inlet socket; and a power cord separately molded from the microwave oven. A guide protrusion(112) is molded in any one between the inlet socket and the power cord plug and a guide groove is molded in the other one between the inlet socket and the power cord plug. Thus, the inlet socket and the power cord are not compatible so an exclusive power cord for the microwave oven is necessary. Therefore, troubles caused by rated current difference are prevented.
