Abstract:
An impeller washing machine, comprising an outer tub (2), an inner tub (3) and an impeller (4). The inner tub (3) can rotate relative to the outer tub (2), and the impeller (4) can rotate relative to the inner tub (3). The impeller washing machine further comprises a power system (5) and a housing (6), wherein the power system (5) comprises a gear shifting mechanism (52); the gear shifting mechanism (52) comprises an upper gear sleeve (521), a connector (522) and a lower gear seat (523); and the housing (6) is sleeved on the outer side of a part of the power system (5). When the connector (522) is connected to the upper gear sleeve (521), the impeller washing machine is in a rotary tub washing mode in which the inner tub (3) and the impeller (4) rotate in the same direction; when the connector (522) is connected to the lower gear seat (523), the impeller washing machine is in an impeller washing mode in which the inner tub (3) does not move and the impeller (4) rotates; and when the connector (522) is neither connected to the upper gear sleeve (521) nor connected to the lower gear seat (523), the impeller washing machine is in a hand scrubbing mode in which the inner tub (3) and the impeller (4) rotate in opposite directions.
