Abstract
A time-saving front-loading washing machine comprises a hosing, a door, an outer tub transversely arranged inside the housing, a cylinder transversely arranged inside the outer tub, and lifting ribs on the inner wall of the cylinder. The outer tub is provided with a front cover plate which is provided with a washings access hole and a beater access hole. A beater is transversely disposed at the top of an inner cavity of the cylinder and comprises a transversely extending beater plate and a rotary shaft extending forward from the center of a front disc plug. The beater rotates in a direction opposite to the rotation direction of the cylinder. When washings carried in the cylinder are about to reach the top of the cylinder, the beater plate rotating in a direction opposite to the rotation direction of the cylinder touches the washings that attach the cylinder and strips off the washings from the cylinder, so that washing is complete. If the front-loading washing machine has the dewatering function, the beater can transversely move into or out of the cylinder; during dewatering, the rear disc plug locates inside the beater access hole and plugs the beater access hole, and no influence occurs to dewatering.
