Abstract: A washing machine contains a wash tub, an impeller and a motor. Clothing is put into the tub and the load is detected. Water is added until the water level is below or equal to load height. To begin washing, the impeller drives the clothing to overturn, resulting in generating three types of water flows: agitating flow, enhancing flow and balancing flow. At first, the agitating flow breaks the balance of the load to disperse clothing, then the enhancing flow overturns clothing for washing. Finally, the balancing flow maintains the circulation path for the load balance overturning. Single sequential control or repeatedly alternating cycle control of the three types of water flows can be adopted for washing. The invention can save water, improve washing efficiency and avoid intertwining of clothing, characterized by full-range, thorough, repeated and efficient washing.

Abstract: A dual-stroke safety switch of a washing machine has a control switch mounted in a base, and a control rod movably connected to the base. The control switch comprises a first control switch and a second switch. The control rod has two motion strokes respectively for controlling the switch-off of the first control switch and the second switch, and the motion stroke for the switch-off of the first control switch is less than the motion stroke for the switch-off of the second control switch. The different strokes of the control rod substantially reflect different degrees of eccentricity of a water tub. The switch-off of the first control switch indicates that small eccentricity of the water tub takes place, and the switch-off of the second control switch indicates that there is serious eccentricity.

Abstract: A first positioning structure is arranged at the bottom of the inner tub of a washing machine, and a second positioning structure is arranged at the bottom of the outer tub. When the two positioning structures come into concave-convex cooperation, the inner tub is locked; and when the two positioning structures separate from each other, the inner tub is unlocked. A locking hole is formed at the bottom of the inner tub; a stretchable and contractible locking rod is arranged at the bottom of the outer tub; when the locking rod projects into the locking hole, the inner tub is locked; and when the locking rod separates from the locking hole, the inner tub is unlocked. During washing, the inner tub is locked without water between the inner tub and the outer tub.

Abstract: A reduction clutch for positioning an inner tub has an input shaft connected to an output shaft. An input shaft sleeve is connected to an output shaft sleeve. A clutch shaft sleeve slides axially downward to connect to a driving device and slides upward to connect to a fixed disk at one position in the circumferential direction. The positioning of the input shaft sleeve, the output shaft sleeve and an inner tub in the circumferential direction is achieved by the connecting position. A first water drainage hole is arranged at the bottom of the inner tub. An included angle between a protrusion on the upper portion of the clutch shaft sleeve and the first water drainage hole of the inner tub is equal to an included angle between a recess on the fixed disk fitting with the protrusion and the water drainage control mechanism on the outer tub.

Abstract: A self-cleaning washing machine includes an outer tub and an inner tub, a chamber between the outer tub and the inner tub is provided with cleaning particles for cleaning the inner wall of the outer tub and the outer wall of the inner tub, an accommodating chamber for collecting the cleaning particles is connected to a drainage outlet of the outer tub; a shield cover arranged at the drainage outlet rises or falls with the change of the water level in the washing machine or the control device to open or at least partially close the drainage outlet so that the cleaning particles flow into the chamber or back into the accommodating chamber. By setting the shield cover, the cleaning particles are not sucked out from the accommodating chamber and enter between the inner tub and the outer tub to avoid noise when the washing machine is dewatering.

Abstract: A self-cleaning drum washing machine, comprises a coaxial drum and outer tub. Cleaning particles are arranged between the drum and the outer tub. Structures between the drum and the outer tub opposite to each other are smooth. A flange is fixedly connected to the bottom of the drum; the outer portion of the flange has a smooth structure or an enclosed cavity is arranged on the outer portion of the drum bottom; the flange is arranged in the cavity; a shaft hole is arranged at the center of the cavity; and a drum shaft sticks into the cavity through the shaft hole and is connected to the flange. The smooth structures go against the attachment of dirt, so that the outer wall of the drum and the inner wall of the outer tub can be conveniently cleaned by the cleaning particles.
