  • Patent number: 9735652
    Abstract: A washing machine includes a tub; a drum arranged in the tub; and a motor mounted on the rear wall, the motor including a stator and a rotor. The stator includes a stator core, a first insulator and a second insulator. The rotor includes a rotor frame including a bottom, air inlets formed at the bottom, and a side wall extended from the bottom. The first insulator is disposed between the stator core and the bottom of the rotor frame, the first insulator including at least one heat dissipation hole. The second insulator is disposed between the stator core and the rear wall of the tub, the second insulator including at least one guide member to position the second insulator on the rear wall of the tub. The guide member is exposed through the dissipation hole when the stator is coupled to the rear wall of the tub.

  • Publication number: 20070163284
    Abstract: Structure for enhancing efficiency in a cooling system for a Kimchi storage containing a plurality of storage chambers includes a compressor, a condenser, a capillary tube, and an evaporator which are sequentially tubularly connected to one another. An accumulator is arranged along a suction pipe (or an inhalation tube) which is an outlet tube of each evaporator associated within each of the plurality of storage chambers. Coolant is sent to and collected in the accumulator from each evaporator through the suction pipe. Simultaneously, the coolant collected in the accumulator is sent to the compressor through s suction pipe (or an exhaust tube). The capillary tube connected between the condenser and the evaporator contacts the accumulator to perform a heat exchange. It is preferable that the capillary tube is arranged to pass through the inside of the accumulator.
