  • Patent number: 7568366
    Abstract: A drum type washing machine including a tub installed in a cabinet is disclosed. The drum type washing machine includes a drum performing washing, a motor rotating the drum, bearing housings having bearings to support a rotation shaft, a suspension connected to the bearing housings and the cabinet to mitigate vibration generated during rotation of the drum, a bracket installed to the bearing housings to form the rear side of the tub, and a gasket installed between the bracket and the tub to seal the tub and to prevent vibration from being transmitted from the bracket to the tub. Volumes of the tub and the drum can be easily increased without increasing the volume of the cabinet. Even when the volume of the washing machine is changed, only one of the tub and the bearing is housings, which is not applicable to the drum type washing machine having the changed washing capacity, is selectively replaced. Thus parts can commonly used in various drum type washing machine having different volume.

  • Patent number: 7428954
    Abstract: Disclosed herein is a damper for use in a drum type washing machine, which can support a tub of the washing machine and absorb vibration of the tub. The damper comprises a cylinder, a piston partially inserted inside the cylinder, and a fixed damping member and movement prevention means, which are installed around an inserted portion of the piston inside the cylinder so that they are spaced apart from each other, and adapted to allow the piston to be stably supported inside the cylinder even in case that a tub of the washing machine vibrates in a non-axial direction of the cylinder and piston, thereby restricting a relative angular rotation of the cylinder and piston and preventing rubbing and collision caused between a lower end of the cylinder and the piston.

  • Patent number: 7412852
    Abstract: The present invention provides a washer, damper thereof, and control method thereof, by which noise is reduced by adjusting a damping force of the damper in a manner of turning on/off power of the damper according to an oscillation frequency of a vibrating body such as a washer. The control method reduces noise by supplying power to a damper in an excessive vibration state of a vibrating body such as a washer or by cutting off the power supplied to the damper in a normal vibration state of the vibrating body.

  • Publication number: 20080072693
    Abstract: Provided are a scent supply apparatus and a washing/drying machine including the same. The scent supply apparatus of a washing/drying machine including a tub in a casing, and a guide duct carrying air into the tub, is detachably installed at one side of the guide duct and supplies a scent into the tub. Because the scent supply apparatus is installed in the guide duct, the scent may be forcibly supplied into the washing/drying machine by the air being introduced into the tub from the guide duct. Accordingly, the scent may be actively supplied into the washing/drying machine, without depending only on its own diffusion, thereby improving scent supply efficiency. Also, when the scent source is exhausted and there is a need for replenishment thereof, a user may easily perform the replenishment of a scent source.

  • Patent number: 7325422
    Abstract: In a washing method of a drum type washing machine, a large amount of the laundry can be more effectively washed by effectively transmitting a mechanical force to the laundry by repeatedly and forcedly rotating a drum forward (or clockwise) or backward (or counterclockwise) for a short predetermined time. Through continuous rotation of the drum of the drum type washing machine, a falling washing is performed such that the laundry in the drum is washed by falling by a gravity, or a reversing washing is performed such that the laundry is washed by repeatedly rotating the drum forward (or clockwise) or backward (or counterclockwise) for a short predetermined time, thereby improving energy efficiency through economizing a washing time and washing water according to the amount of the laundry, and also preventing a waste of power by driving a heater at a proper time.
