Abstract: A laundry treatment machine may include an outer tub having an opening at a top through which laundry is inserted. The outer tub may contain wash water for washing the laundry. An inner tub may be rotatably provided inside the outer tub. A pulsator may be rotatably provided at a bottom of the inner tub to generate a current or flow of water flowing at a lower part of the inner tub. A water current generating protrusion that protrudes inward from a peripheral surface of the inner tub and extends upward from a bottom end of the inner tub may generate a current or flow of water flowing along an upper part of the inner tub.

Abstract: A vibration limiter of a washing machine is disclosed. The vibration limiter includes a housing installed at one of a cabinet and a tub, a contact plate disposed within the housing such that the contact plate comes into contact with the other of the cabinet and the tub when the tub vibrates, a spring for elastically supporting the contact plate, a rotating member rotatable by at least one of the spring and the contact plate, and an oil damper engaged with the rotating member. The oil damper complementarily acts with the spring, to effectively absorb vibration. Accordingly, it is possible to reduce the size of the spring and to secure enhanced reliability even after prolonged use.
