摘要： An inner drum of a washing machine has a plurality of hollow lifting ribs arranged on the side wall of the drum that communicate with the interior of the drum. At least one drainage port communicating with the hollow portions of the lifting ribs is formed in the side wall of the drum. A sealing valve is located inside each lifting rib at each drainage port. During high-speed rotation of the drum, valve bodies of the sealing valves move along a radial center direction of the drum under a centrifugal force, to open the drainage ports. Through this arrangement, discharging water flow in the drum to the outside from the hidden drainage ports is achieved. Meanwhile, centrifugal force during the high-speed rotation of the drum is used to control valve cores of the sealing valves such that the drainage ports are automatically opened for drainage from the drum.

摘要： An inner drum cover is provided at a drum opening of an inner drum of a washing machine, the inner drum cover is used to open or close the drum opening, so that the inner drum forms a closed container after the drum opening is closed by the inner drum cover. The inner drum can perform washing after the inner drum cover is correspondingly fastened to the drum opening, so that clothes only come into contact with washing water in the sealed inner drum in a washing process. In this way, a case in which the clothes are contaminated because washing water between the inner drum and an outer drum flows into the inner drum is avoided, washing cleanliness of the washing machine is greatly improved, and incomplete washing of the clothes caused by contamination of the washing water between the inner drum and the outer drum is avoided.

摘要： The disclosure relates to a draining structure of a washing machine and a draining method. An inner drum is installed in a housing of the washing machine. The inner drum is a tapered drum with a smaller diameter at one end and a larger diameter at the other end. A draining flow passage is arranged at the larger diameter end. One end of the draining flow passage communicates with the larger diameter end. The other end of the draining flow passage penetrates the inner drum and communicates with a drain pipe. The inner drum rotates and washing water flows to the larger diameter end along the tapered inner wall by centrifugal force. Washing water is drained out from the inner drum through the draining flow passage arranged at the larger diameter end and then drained out through the drain pipe to realize the discharge of washing water.

摘要： A sealing valve plug structure includes a valve plug column corresponding to the drain opening formed in the side wall of an inner drum, and a counterweight hinged to the upper end of the valve plug column. The sealing valve installation structure is installed on the side wall of the drum, and the reset spring is clamped between the sealing valve installation structure and the valve plug column. The counterweight is used to generate an action, under the action of centrifugal force, to open the drain opening, and the valve plug column is reset by the reset spring to make the valve plug block the drain opening, to thereby open and close the drain opening. A cleaning-free washing machine having an inner drum sealed by the sealing valve plug structure is also disclosed.

摘要： A laundry device comprises an outer tub, an inner tub, an inner magnetic ring and an outer magnetic ring. One of the inner magnetic ring and the outer magnetic ring is directly or indirectly fixed on a bottom wall of the inner tub and positioned at the outer side of the bottom wall of the inner tub, and the other one is directly or indirectly fixed on a bottom wall of the outer tub and positioned at the inner side of the bottom wall of the outer tub. An upper end face and a lower end face of the inner magnetic ring have the same polarity as the upper end face and the lower end face of the outer magnetic ring so that a radial repulsion between the inner magnetic ring and the outer magnetic ring is used to suppress vibration of the inner tub and/or the outer tub.
