  • Patent number: 8756958
    Abstract: An impulse type shock wave flash dyeing machine is disclosed. A row of joint nozzles can send out high-speed air flows to prompt fibrous fabric to spread out and move in the dyeing machine through the effect of impulse. Dyes or processing agents may be converted into fine mist and is carried by the high-speed air flows to blast the fibrous fabric (3). Therefore, the dyes or processing agents can enter the fibrous fabric (3) quickly and can diffuse or spread out in the fibrous fabric (3) swiftly through strong elastic and inelastic collisions as well as the effect of shock wave. Such collisions and effect can impart enough energy to the dyes or processing agents and convert non-activated molecules into activated molecules. In addition, the effect of corona discharge may be used to generate high-energy particles and hence the goals of clean and swift processes may be achieved.

  • Publication number: 20140033444
    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 the 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.

  • Publication number: 20110016638
    Abstract: In a washing machine according to the present invention, if a washing step is ended, a distribution step that the inner tub containing the washing water is rotated in one direction and fabrics is distributed to a side wall of the inner tub and the washing water is discharged to outside is performed. Because a fabric is evenly distributed in the distribution step, a dehydration step can be performed without carrying out a separate procedure for avoiding unbalance. Therefore, energy such as washing time and power used during the operation of the washing machine and amount of water used can be saved. Also, since a washing machine according to the present invention rotates the inner tub not only during the distribution step but also during the hydration step afterwards, operation of a clutch used to selectively rotate the pulsator and the inner tub at the time of entering to the dehydration step from the distribution step is not required.

  • Patent number: 7614262
    Abstract: An automatic washing machine comprises a spin tube coupled to the basket and an agitator shaft coupled to an agitator mounted in the basket. A motor coupled to the agitator shaft applies a torque the agitator shaft and thereby the agitator in first and second torque directions. A clutch couples the spin tube to the agitator shaft for cooperative rotation of the basket and the agitator regardless of the rotational direction of the agitator shaft. Because of the dual directionality of the clutch, reversing the motor simultaneously dynamically brakes the basket and the agitator, thereby eliminating the need for a separate friction brake for the basket.

  • Patent number: 7506525
    Abstract: An automatic washing machine comprises a wash tub and a wash plate movably mounted within the wash tub for imparting mechanical energy to articles of fabric in the wash tub. The wash plate comprises a base and a blade that extends from the base and terminates in a tip. According to the invention, at least the tip of the blade is formed by an insert. The insert is made from a relatively hard and wear resistant material that is different than the material of the impeller body. As a result, the wear resistance and performance of the impeller is improved without significantly increasing the overall cost of the impeller.

  • Patent number: 7216516
    Abstract: A wobble joint particularly useful for supporting a wash plate in a wash basket of an automatic washing appliance includes inner and outer races formed with mating part-spherical surfaces having common centers of curvature about a longitudinal axis of the joint. Anti-rotation structure acts between the inner and outer races to prevent relative rotation of the races about the longitudinal axis, and cooperates with the part-spherical surfaces to restrict the races to two degrees of tilting movement about respective tilt axes disposed perpendicular to the longitudinal axis and to one another, such that one of the races is thereby supported for wobbling movement relative to the other of the races. In a washing appliance application, the wash plate is fixed to the outer race and wobbles relative to the inner race.

  • Patent number: 7131159
    Abstract: A method of controlling a wobbling washing machine which performs a washing operation, a rinsing operation, and a disentangling operation by wobbling a washing plate. The disentangling operation includes wobbling the washing plate at a speed higher than a wobbling speed of the washing plate for performing the washing or rinsing operation. The method allows a load of laundry to be effectively disentangled by a wobbling action of the washing plate at a motor's rotating speed which is preset to be higher than the motor's rotating speed at the washing or rinsing operation. The method further includes performing the disentangling operation before and after each of a first spin-drying operation and a final spin-drying operation to further minimize tangling of the laundry.
