Abstract: The present invention relates to a washing machine comprising an outer tub containing water, and an inner tub disposed in the outer tub to accommodate laundry and rotated about a horizontal axis. The washing machine includes: a motor for providing rotational force; an outer shaft that has a first hollow, and rotates the inner tub; an inner shaft disposed in the first hollow and rotated by the motor; a pulsator disposed in the inner tub and coupled with the inner shaft; a planetary gear train for transmitting rotational force of the motor; a carrier mover which has an outer circumferential surface that is spline-coupled to an inner circumferential surface of the outer shaft, and an inner circumferential surface that is screwed with an outer circumferential surface of the clutch carrier; and a stopper restricting movement of the carrier mover, thereby achieving various washing modes with a simple mechanism by rotating the inner tub and the pulsator.

Abstract: A reciprocating compressor includes a cylinder that defines an inner space, a piston that is located in the inner space of the cylinder and that defines a compression space configured to receive refrigerant, a discharge cover that is coupled to a side of the cylinder and that defines a discharge space configured to receive refrigerant discharged from the compression space, and a valve plate that is located at a side space defined at the side of the cylinder and that partitions the side space into the compression space and the discharge space. The valve plate defines a discharge hole through which the compression space and the discharge space communicate with each other, in which the discharge hole includes an inlet that faces the compression space and an outlet that faces the discharge space. The inlet and the outlet have different shapes.
