Abstract

A tableware sterilizing and drying apparatus of the present invention includes a rotatable base plate, several frames, and a fixation wheel. The frames have rotatable members, which are revolved by rotation of the base plate, and rotated by engagement or contaction of the fixation wheel. Thus, the rotatable member is provided for tableware to be placed thereon. The tableware is then brought drying and sterilizing with flipping motion. Surface of the tableware can be fully dried and sterilized.

Claims
