摘要： Cleaning particles are arranged in a space between the inner tub and the outer tub of a washing machine. A drainage and dewatering control method comprises: opening a drainage valve; determining the amount of the cleaning particles per each unit volume of water in the space; and controlling the rotating speed of the inner tub. Drainage and dewatering processes are divided into at least two control stages according to the amount of the cleaning particles per each unit volume of water in the space, different rotating ways of the inner tub are set in respective stages, and the rotating speed of the inner tub is higher in the stage that the amount of the cleaning particles per unit volume of water is larger. A control stage is selected according to the detected amount of the cleaning particles per unit volume of water in the space.

摘要： A washing machine includes an outer barrel and an inner barrel rotatably arranged in the outer barrel. During the washing/rinsing process, the inner barrel contains water, and there is no water between the inner barrel and the outer barrel. A drainage hole is arranged on the bottom of the inner barrel. A drain-sealing device and a driving device are arranged on a bottom of the inner barrel. The drain-sealing device comprises a sealing part cooperating with the drainage hole to control the opening/closing of the drainage hole, and a connecting part connected with the driving device. During washing/rinsing, the sealing part of the drain-sealing device keeps the drainage hole closed. During draining/dehydrating, the drain-sealing device opens the drainage hole under the action of the driving device. The drain-sealing device and the driving device are installed on the inner barrel, and rotate with the the inner barrel during dehydrating.

摘要： A pulsator of washing machine and a washing machine, a base body of the pulsator is disk-shaped. A central portion is arranged at and protrudes from a center of the base body of the pulsator, on an upper surface of the base body is provided with and a stirring blade protruding the base body and a groove, the stirring blade extends from the central portion of the base body to a outer periphery of the base body. Moreover, a bottom surface of the base body is provided with a smoothly undulating surface corresponding to the upper surface. The undulating surface does not stiffly protrude from the bottom surface of the base body, so there is no hard angle formed between the undulating surface, or between the undulating surface and the other surface of the base body.
