Abstract: PURPOSE: A water saving device in electric washing machine is provided to improve a structure of a dehydrating tub, so that the consumption amount of water and detergent is saved. CONSTITUTION: A water saving device in electric washing machine comprises a dehydrating openings(311) partially perforated on an upper end of a dehydrating tub(30) in which laundry is thrown and a buoyancy member(38) arranged between a bottom surface of the dehydrating tub(30) and a water reservoir(20) so as to close a drain hole(361) formed on the bottom surface of the dehydrating tub(30) by being floated by means of buoyancy. Accordingly, upon washing and rinsing processes, an adequate amount of washing water is feed into the dehydrating tub(30) containing laundry while the water flows into the water reservoir(20) up to a lower water level than that of the dehydrating tub(30), so that water consumption amount required in the washing and rinsing processes is considerably reduced. Also, since a time required to feed water is shortened, consumption electric power is reduced. In addition, since the using amount of detergent as well as water is reduced, water pollution caused by life waste water is reduced.
