Abstract: Disclosed are a self-cleaning washing machine and a control method thereof. The washing machine includes inner and outer drums defining a chamber therebetween, a wave wheel, a water drainage apparatus, cleaning pellets provided in the chamber for cleaning drum walls between the inner and outer drums, and an isolating structure for preventing the cleaning pellets from escaping from the chamber. The isolating structure includes a filtration mechanism arranged in the water drainage apparatus to prevent the cleaning pellets from being flushed away when water is drained, and/or a grid mechanism arranged at the bottom of the inner drum to prevent the cleaning pellets from entering the inner drum. Operably, in the water-draining and/or spin-dry process, the inner drum is controlled to carry out different actions, making the cleaning pellets together with the water flow through a water drainage opening to be collected by a water drainage valve.

Abstract: A washing machine includes an inner tub arranged in an outer tub and a rotatable wave wheel. As every 1 kg load is increased, the height difference h1 between the clothes and water satisfies the formula h1=(?D2h?4V1)/(K?D2), wherein D is the diameter of the inner tub, h is the height of the wave wheel, V1 is the volume of the wave wheel, and K is the optimal clothes load between the wave wheel and the inner tub within the wave wheel height. The clothes overturn periodically while rotating along with the wave wheel. The clothes move towards the center of the wave wheel along the wave wheel while moving upward, overturn outwards in a uniform wobble way after reaching the climax of the wave wheel and fall to the bottom of the inner tub along the inner tub wall, and move towards the center of the wave wheel again.

Abstract: A self-cleaning washing machine includes an inner drum, an outer drum and a chamber defined therebetween. The chamber is provided with cleaning pellets rotatable with water flow for cleaning walls of the inner and outer drums. An inner surface of the bottom of the outer drum includes at least one structure of: an inclined area formed on the inner surface along a circumferential direction with a height near a center of the bottom of the outer drum higher than that near a side wall of the outer drum; an annular water channel formed on the inner surface, being adjacent to the side wall of the outer drum, and recessed along the circumferential direction; and a water blocking convex rib formed on the inner surface corresponding to a side of the water drainage port along a rotation direction of the inner drum during dewatering.

Abstract: A music washing machine and a control method thereof. The washing machine includes a motor for introducing a washing water flow. The motor is connected to a control device for performing mutual conversion between a rotation and stopping ratio and/or the rotation speed of the motor and a musical characteristic signal, so that the music emitted by an output device synchronizes with the rotation and stopping ratio and/or the rotation speed of the motor during working of the washing machine. By a conversion device of the washing machine, mutual conversion between the rotation and stopping ratio and/or the rotation speed of the motor of the washing machine and the musical characteristic signal is performed, so that the output device emits music corresponding to the rotation and stopping ratio and/or the rotation speed of the motor during working of the washing machine.

Abstract: A dryer includes a sealed drum, a heat pump system, a vacuum device and a steam generating device. The steam generating device connects with the interior of the drum to introduce hot steam into the interior of the drum. The vacuum device connects with the interior of the drum. The heat pump system is arranged external to the drum. Heat generated by the heat pump device is exchanged with the outer surface of the drum through a liquid medium so as to heat the wet clothes in the drum. Simultaneously, damp-hot air mixed with the water vapor in pumped from heating clothes in the drum by the vacuum device and the hot steam pumped into the drum and contacted with clothes are cooled and condensed into water. The water produced by damp-hot air is connected with water provided by the steam generating device.

Abstract: Disclosed are a self-cleaning washing machine and a control method. The washing machine comprises an outer drum (1), an inner drum (2), a wave wheel (3) and a water drainage apparatus (4), wherein cleaning pellets (6) to clean the inner wall of the outer drum and the outer wall of the inner drum are provided in a chamber (5) between the inner drum (2) and the outer drum (1).
