PURPOSE: To relieve a physically handicapped person and a person having a weak grip of the pain of wringing work of a dish towel, a wet towel. etc., and to obtain a function of requiring dehydration in a cooking course in a device in which a sink and a small centrifugal dehydrator are combined.

CONSTITUTION: A dehydration basket 7 is smoothly rotated without horizontal vibration, supported by a roller 4. A driving motor 14 and the dehydration basket 7 are not directly coupled with a rotating shaft and a magnetic flywheel 13 applies magnetic force to the metal disc of the bottom part of the dehydration basket 7 so that the dehydration basket 7 is rotated by the action of magnetic force of the magnet flywheel 13 through a connecting shaft 10. Therefore, the dehydration basket 7 is freely attachable and detachable to and from a dehydrator body.
