A draining anti-siphon device has a water outlet pipe comprising a first water pipe and a second water pipe which are connected with each other, the pipe diameter of at least part of the second water pipe is larger than the pipe diameter of the first water pipe, one end of an air pipe is communicated with the second water pipe, and the communicating position of the air pipe and the second water pipe is located at a radial surface of the second water pipe, so that siphon reverse flow is prevented by means of a diameter changing structure of the air pipe and the water outlet pipe. In a washing machine, the draining anti-siphon device is mounted on a draining hose, the air pipe of the draining anti-siphon device is communicated with the outer drum of the washing machine.

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.

A suspender disengagement detection apparatus for a washing machine, comprising pressure sensors and a controller. The pressure sensors are electrically connected to the controller. The controller is electrically connected to a drive motor of the washing machine. In a working process of the washing machine, the pressure sensors are mounted on the joint of at least one suspender and the housing of the washing machine, and/or the joint of the suspender and the suspender base of the outer tub of the washing machine to detect a pressure, and a detection result is fed back to the controller; and the controller determines, whether a suspender is disengaged according to feedback information, and further controls the change in a working state of the drive motor of the washing machine.

A variable damping shock absorber has a sleeve and a piston rod, one end of the sleeve being an opening and the other end being closed, one end of the piston rod being inserted through the opening and slidable in an axial direction inside the sleeve. Two sets of friction plates are arranged in the axial direction between an inner wall of the sleeve and an outer wall of the piston rod. A friction plate is fixed in the axial direction with the inner wall of the sleeve, and a sliding friction force between each friction plate set and the outer wall of the piston rod gradually decreases from the closed end to the opening end of the sleeve. The structure can ensure that the damping force is variable under different load and rotational speed conditions.

Variable damping shock absorber

A water-saving washing machine and a control method are provided. The washing machine includes a washing drum and an outer drum, where a circulating pipeline is arranged between an outer drum drainage outlet and an outer drum water inlet, a drainage pump and a main filter are arranged on the circulating pipeline, a pre-filter is further arranged on the circulating pipeline, the pre-filter is located between the drainage pump and the main filter, and a compactness of a filter screen of the pre-filter is lower than that of a filter screen of the main filter.
