A washing machine in which a detergent case is located below a washing tub unit and detergent and wash water are supplied from the detergent case to the washing tub unit by a pump. An overflow hole to prevent overflow of water to the outside the detergent case is provided on the detergent case, and the detergent and the wash water do not overflow the detergent case and are discharged to an outside of the washing machine through the overflow hole when the pump breaks down.

Washing machine and detergent case thereof

A washing machine having a structure which stably supports a hose or a wire used in the washing machine to prevent sagging or movement of the hose or the wire. The washing machine includes a main body, a spin basket disposed within the main body, an upper cover connected to the upper portion of the main body, a detergent box connected to the bottom surface of the upper cover to supply detergent to the inside of the spin basket, a water supply valve connected to the rear end of the upper cover, a water supply hose connecting the water supply valve to the detergent box, and a support bracket connected to the bottom surface of the upper cover to support the water supply hose so as to prevent sagging of the water supply hose.

Washing machine

A drum type washing machine includes a housing; a spin tub rotatable by a driving motor through a rotating shaft; a balancer installed at a rear section of the spin tub; a shaft flange including a hub section to fixedly install the rotating shaft and a plurality of arm sections extending radially outward from the hub section and mounted to the spin tub so as to uniformly transfer the rotational force to the spin tub; and a rear cover provided on the rear section of the spin tub. The balancer is disposed adjacent to the rear cover and the shaft flange such that the first annular-shaped member contacts the shaft flange and the second annular-shaped member contacts the rear cover.

Drum type washing machine

A washing machine in which performance of a balancer is improved and a control method thereof. The washing machine includes at least one balancer housing provided with a ring-shaped channel, at least one mass body movably disposed in the channel, a confinement unit to confine the at least one mass body to the at least one balancer housing so as to allow the at least one mass body to be rotated under the condition that the at least one mass body is fixed to the at least one balancer housing, an adjustment unit to release confinement of the at least one mass body so as to allow the at least one mass body to descend due to gravity during rotation of the drum, and a control unit to control the adjustment unit so that unbalanced load is offset by the at least one mass body.

Washing machine and control method thereof

A front loading washing machine including a housing; a water reservoir installed in the housing for containing washing water; a spin tub provided in the water reservoir to hold laundry to be washed, the spin tub having an annular recess and rotating with respect to a horizontal axis of the washing machine; and at least one balancer installed in the annular recess of the spin tub, the balancer comprising an annular shaped race formed of a plastic material.

Washing machine having balancer

A washing machine is provided having at least one balancer and a method of manufacturing a balancer thereof is further provided, the method and machine capable of reducing a manufacturing cost and an assembly time, and allowing the balancer assembled to a spin tub to be easily replaced with a new balancer. The balancer applied to the washing machine and the method of manufacturing the balancer of the washing machine are adapted such that a pipe is formed in an annular shape and is assembled to a spin tub, so that a manufacturing cost and an assembly time can be reduced to improve mass productivity. Further, when the balancer is determined to fail after being assembled to the spin tub, the balancer can be rapidly and conveniently replaced with a new balancer, so that material costs can be reduced.

Washing machine having balancer and method of manufacturing balancer thereof

A drum type washing machine including a balancer capable of rapidly reducing vibration of a spin tub. The drum type washing machine includes a spin tub which is rotated by receiving rotational force from a driving motor through a rotating shaft, a rear balancer having an annular shape and being coupled to the spin tub, and a shaft flange provided at a center portion thereof with the rotating shaft and coupled to the spin tub so as to uniformly transfer the rotational force to the spin tub. The rear balancer is supported on a rear surface of a rear cover by the shaft flange. Thus, the balls accommodated in the balancer are prevented from moving out of the balancer, even if the balancer is broken due to long-period use.

Disclosed herein is a washing machine including an overflow defined through a portion of one side of an upper part of a tub and formed in the shape of a cutout and guide ribs protruding from the outer circumference of the tub to guide wash water drained through the overflow. The overflow is formed by cutting one side of the upper part of the tub, so that the washing machine has a simple overflow structure.

Tub with overflow and washing machine having the same

A drum type washing machine including a housing, a rotating spin tub to hold laundry to be washed and a ball balancer coupled to the spin tub to compensate for a dynamic imbalance during rotation thereof. The ball balancer includes a first plastic member and a second plastic member joined to each other to form a closed internal space in which a plurality of balls and viscous fluid are accommodated, the first plastic member includes a first side wall, a second side wall and a connecting wall to form a three-sided annular-shaped structure having an open side, and the second plastic member is adapted to cover the open side of the first plastic member. A diameter of each of the balls is smaller than a depth of the three-sided annular-shaped structure measured from the connecting wall to a top of the first side wall.

A drum type washing machine including a housing, a spin tub, and a ball balancer coupled to the spin tub, the ball balancer including a first plastic member and a second plastic member joined to each other to form an annular-shaped race, the first plastic member including a first side wall, a second side wall and a connecting wall to form a three-sided annular-shaped structure having an open side, and the second plastic member adapted to cover the open side, the three-sided annular-shaped structure having a U-shaped cross-section with a first rounded inside corner formed between the first side wall and the connecting wall and a second rounded inside corner formed between the second side wall and the connecting wall. A radius of curvature of each of the first and second rounded inside corners is greater than a radius of curvature of opposite diagonal inside corners of the annular-shaped race.

A drum type washing machine, including a housing, a spin tub to hold laundry to be washed, the spin tub rotating with respect to a horizontal axis of the washing machine, and a ball balancer coupled to the spin tub to compensate for a dynamic imbalance during rotation thereof, the ball balancer including a first plastic member and a second plastic member joined to each other to define a closed internal space in which a plurality of balls and viscous fluid are accommodated, the first plastic member having an open side, and the second plastic member adapted to cover the open side of the first plastic member. The first plastic member includes a plurality of supports formed on an outer surface thereof to establish contact with the spin tub, and the ball balancer is fastened to the spin tub via a plurality of screw members.

A front loading washing machine including a housing; a water reservoir installed in the housing to contain washing water; a spin tub provided in the water reservoir to hold laundry to be washed, the spin tub rotatable with respect to a horizontal axis of the washing machine, the spin tub including a cylindrical body, a front cover and a rear cover, the front cover having a front wall with an opening formed therein for receiving laundry and an annular recess having a predefined depth formed in the front wall of the front cover such that an outer annular side wall defining the annular recess establishes direct physical contact with a predefined area of an inner surface of the cylindrical body; and at least one balancer installed in the annular recess of the spin tub, the balancer comprising an annular shaped race formed of a plastic material.
