Abstract
Disclosed is a microwave heating apparatus which comprises a turntable for reducing the irregularity of heat with the rotation movement of a subject to be heated within a heat chamber, a bread casing used for automatically performing an entire process of kneading raw ingredients, fermentation, gas escape, baking and the like, a first driving shaft made of a metal pipe and provided to drive a kneading blade mounted within the bread casing, and a second driving shaft made of a microwave-permeable dielectric substance provided to drive the turntable, the second shaft being arranged to pierce a hollow portion of the first driving shaft. According to the aforementioned construction, the turntable and the kneading blade can be effectively driven by the respective optimum motors. A choke cavity and a disk shaped conductive plate prevent microwave energy from leaking out of the heat chamber along the respective driving shafts.
