  • Patent number: 8746016
    Abstract: A suspension (1) of a washing machine has a mechanical assembly resting on the bottom of the cabinet (3) by means of a lower cushion including plates (5 and 7) and shock absorbers (6) and a liquid containing casing (4). The suspension system (1) is intended to absorb the movement of the mechanical (wash group) assembly during a centrifugal spin, reducing the transmissibility of forces/movements to the external cabinet (3), while the liquid containing casing provides a cost-effective counterbalance within the system.

  • Patent number: 8739581
    Abstract: A washing machine includes a water tub, an electric motor, and a control device. The motor comprises a stator including a stator coil, a rotor magnet arranged circumferentially with respect to the rotor, and a control device. The rotor magnet includes a permanent magnet. When the control device applies a first voltage to the stator coil in a wash step of the washing operation, the rotor magnet is magnetized so that a magnetic flux of the rotor magnet acting on the stator is increased without reversal of a direction of magnetization. When the control device applies a second voltage to the stator soil in a dehydration step of the washing operation, the rotor magnet is magnetized so that a magnetic flux of the rotor magnet acting on the stator is reduced without reversal of a direction of magnetization as compared with the magnetic flux in the wash step.

  • Patent number: 8561438
    Abstract: A complex washing machine is disclosed. The complex washing machine includes an auxiliary washing machine that is capable of serving as a pedestal for a main laundry machine, such as a washing machine or a drying machine, and performing a washing operation. The auxiliary washing machine is suitable for washing a small amount of laundry while the auxiliary washing machine serves as a pedestal for supporting the main washing machine, which is placed on the auxiliary washing machine. A bearing housing, which supports a rotary shaft of a motor, and a bottom plate of a tub are connected to each other via a gasket. Consequently, the vibration generated from the tub during washing is minimized.

  • Patent number: 8561439
    Abstract: A fabric treating machine according to the present invention comprises a connector which is disposed at an outer tub and is connected to a driving part which is disposed at either the center or the off-center position of the connector optionally. Therefore, not only the direct driving motor but the indirect driving motor can be disposed without change of the outer tub and the connector. Because the common use of the outer tub is possible regardless of the connecting method of the driving part, there are the advantages that the cost is reduced and productivity and assembly are improved.
