Abstract
A microwave oven with a control panel including a case, a circuit board mounted to the case, and a coupling device adapted to couple the case and the circuit board. The coupling device includes a plurality of coupling members protruded from an inner surface of the case. Each of the coupling members has an engagement protrusion at a protruded end thereof. The coupling device also includes a plurality of engagement holes provided at the circuit board at positions corresponding to respective coupling members so that the engagement holes are engaged with the engagement protrusions of the coupling members, respectively. Accordingly, it is possible to mount the circuit board to a rear side of the case in the interior of the case without using fixing screws, in accordance with a single-pass mounting process, thereby achieving an enhancement in the productivity of circuit boards and a reduction in manufacturing costs.
