ABSTRACT:
A dewatering apparatus of an automatic washing machine includes: an unbalance sensor mounted on a controller mounted into a top cover for sensing unbalance of a washing tub during a dewatering cycle; a magnet mounted on the washing machine door and a hall sensor mounted on the controller opposite to the magnet when the door is closed, for sensing whether the door is opened during the dewatering cycle. The unbalance sensor includes a casing in which a roller freely rolls, wherein a displacement (during unbalance of the washing tub) of the roller from a neutral position, is detected by, for example, a photo switch, press switch, or electrical switch, whereby a state of unbalance can be identified.
