ABSTRACT:
Disclosed is a microwave oven comprising, a body divided into a cooking chamber and a device chamber, a magnetron installed in the device chamber of the body, a high voltage condenser and a high voltage transformer, and a blower for cooling elements installed in the device chamber. The blower comprises a fan for forcedly blowing air, and a motor having a stator, a rotor, and at least one fixing rod. The stator is equipped with a bobbin with a coil wound thereon. The stator provides the fan with a driving force. The fixing rod is extended from the stator and coupled with a rear panel of the body. The fixing rod passes through the rear panel, and is formed with a screw part at an end part thereof which is assembled with a nut. The blower for cooling the devices for generating microwave is directly fixed onto the rear panel of the body without using a bracket. Accordingly, unit cost is reduced due to a reduced amount of elements. In addition, the number of processes for assembling the blower is reduced, and the assembling efficiency as well as a productivity increase.
