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 small size pulsator-type automatic washing machine comprises a housing, a control panel seat mounted on the top of the housing, a pedestal mounted at the bottom of the housing, an outer tub and an inner tub mounted inside the housing. A direct driving motor and a bearing block are mounted at the bottom of the outer tub. The motor is mounted on the outer tub by fixing elements, and a motor shaft is coupled with a pulsator shaft inside the bearing block. A fastener strap fixes the motor and the bearing block together onto the outer tub of the washing machine, thus reducing occupied space of the washing machine while improving a variety of installation mechanism of conventional washing machine. An insulation unit is disposed in the joint between the motor shaft and the tub shaft, such that the two parts cannot be in direct contact.

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: A washing machine for automatically adding the detergent by negative pressure comprises a water inlet, a detergent container and a tub. A main inflow waterway and a rinse waterway are provided between the water inlet and the tub. A dosing container which communicates with the detergent container is provided between the rinse waterway and the tub. A venturi tube is provided in the main inflow waterway. Due to venturi effect, the main inflow water stream becomes narrower and the water inflowing velocity is accelerated, so that a relative vacuum area which communicates with the dosing container is formed at the rear side of the venturi tube outlet, negative pressure is generated in the dosing container, and the detergent in the detergent container.

Abstract: A seal unit is adapted to a gas dryer. The seal unit is assembled on the chamber rear wall, an end of heating disk is compressing on the seal unit. Said seal unit includes seal loop shaped as a ring, this seal loop is composed of inner fix part with the shape of flat-sheet ring and outer seal part shaped as a closed ring. The seal unit can, bring effective sealing performance, decrease the leakage of hot-air, quicken drying speed and have high efficiency. Additionally, the seal unit can, be easily produced, have high reliability and have better consistency of production quality.

Abstract: The present invention has disclosed a washing machine with improved waterway system, said waterway system is comprising softening-electrolysis waterway, modifier-liquid waterway and ion-exchange-resin regeneration waterway, when this washing machine is at work, modifier-liquid combined with alkaline-electrolysis water could replace detergent for washing; meantime, said ion-exchange-resin regeneration waterway could greatly prolong the service life of softening-electrolysis system, and avoid the refluence of wastewater to cause pollution in the washing machine in prior art.

Abstract: This invention is concerning a gas dryer, especially a seal unit of gas dryer. The seal unit is assembled on the chamber rear wall, an end of heating disk is compressing on the seal unit. Said seal unit comprises seal loop shaped as a ring, this seal loop is composed of inner fix part with the shape of flat-sheet ring and outer seal part shaped as a closed ring. This seal unit involved in this present invention would bring effective sealing performance, decrease the leakage of hot-air, fast drying speed and have high efficiency. Additionally, the seal unit is of easily produced, high reliability and better consistency of production quality.

Abstract: A washing machine which has no need of adding detergent by the user and the washing method thereof the said washing method comprises balancing setting the PH surface tension electrical conductivity and hardness of the washing liquid in a certain range, washing in general automatic washing machine with the use of a high PH electrolyzed water combined with a regulator; in which the PH of the said washing liquid is in the range of 8.5-1 I, the electrical conductivity of it is in the range of 261 us/cm-875 us/cm the surface tension is in the range of 2540 mN/m, the hardness is in the range of 5-400 ppm, if necessary 0.20.
