  • Patent number: 11761137
    Abstract: A washing machine and a method for controlling the same are provided. The washing machine includes a first rotary tub, a first driver configured to rotate the first rotary tub, a second rotary tub, a second driver configured to rotate the second rotary tub, and at least one processor configured to control the first driver and the second driver in a manner that the first rotary tub and the second rotary tub rotate. If a rotation speed of the first rotary tub is equal to or higher than a first reference speed, the at least one processor controls the second driver such that a rotation speed of the second rotary tub increases to a target speed and then decreases.

  • Patent number: 6644621
    Abstract: The present invention relates to an ABS solenoid valve. The ABS solenoid valve comprises: a housing coupled within a modulator block; a receiving unit disposed within the housing; a plunger mounted on the receiving unit and having a projection in one end; a compressive spring coupled with the plunger adjacent to the projection; a valve seat supported by the compressive spring and received within the housing; a coupling channel disposed within the valve seat; an orifice communicating with the coupling channel of the valve seat and coupling with a side of the housing; a flow path disposed within the orifice; a channel pipe communicating with the flow path, a flow groove disposed in an outer periphery of the valve seat; and a discharge port disposed in the housing and the orifice and communicating with the flow groove of the valve seat. The channel grooves are disposed in the outer periphery of the valve seat to simplify a fabricating process.
