Abstract: A tub and a washing machine having the same which omit an air chamber cap, thereby reducing production costs and decreasing the number of water leakage points. The tub of the washing machine includes a diaphragm extended downward from the inner surface of the tub to form an air chamber at one side of the lower portion of the tub, and a drain hole formed beneath the air chamber to discharge wash water.

Abstract: A drum washing machine allows a plurality of electric wires to be easily secured in a cabinet, in addition to reinforcing strength of a top plate. The drum washing machine includes a cabinet having an opening at an upper portion thereof, a top plate to cover the opening, and a reinforcement placed at a predetermined position of the opening to support and reinforce the top plate. A wire holder is provided at a predetermined portion of the reinforcement to hold the electric wires arranged in the cabinet. The drum washing machine is provided with the reinforcement, which reinforces the strength of the top plate, and allows the electric wires to be easily arranged and held in the cabinet.

Abstract: A drum type washing machine in which wash water fed to a tub via a water supply pipe is directly supplied into a drum. The washing machine includes a housing, a tub arranged in the housing to contain wash water therein, a drum rotatably mounted in the tub, a water supply pipe adapted to supply wash water into the tub, and a water supply guide unit provided at the tub, to guide the wash water from the water supply pipe to be directly supplied into the drum. Since the wash water is directly supplied into the drum, laundry contained in the drum is wetted by the wash water, immediately after the supply of the wash water. Thus, it is possible to reduce the wash time for the laundry.

Abstract: A drum washing machine which reduces the number of balance weights installed on the rear surface of a tub, and prevents the tub from being cracked due to eccentric rotation. The drum washing machine includes a bearing housing installed on the tub for supporting a rotary shaft; and a bearing housing bracket fixing the bearing housing to the tub, and serving as a balance weight for reducing vibration generated due to the eccentric rotation of a rotary drum. The drum washing machine further includes a balance weight detachably attached to the tub separately from the bearing housing bracket. The bearing housing bracket may be made of cast iron. The weight of the bearing housing bracket may be at least three times the weight of the balance weight. The thickness of the bearing housing bracket is gradually reduced from an opening to an edge portion.

Abstract: A drum type washing machine includes a cabinet which defines an outer appearance of the washing machine, a water tub set inside the cabinet to contain wash water therein, a rotary tub having spin drying perforations and rotatably set in the water tub, and a water turbine which is mounted at an open front of the rotary tub and rotates along with the rotary tub to spray the wash water contained in the water tub into the rotary tub. The water turbine includes an external member having an annular shape, and an internal member having an annular shape corresponding to the external member. The internal member is arranged apart from the external member by a predetermined interval. A vane unit is set between the external and the internal members, and raises the wash water contained in the water tub and sprays the wash water into the rotary tub.

Abstract: A drum type washing machine includes a cabinet, a fixed drum set in the cabinet to contain wash water therein, a rotary drum rotatably set inside the fixed drum, a pump which forcibly pumps out the wash water contained in the fixed drum, and a water circulation device which feeds the wash water pumped by the pump into the rotary drum in a washing operation. The water circulation device includes a storing unit and a spraying unit. The storing unit defines a space which temporarily holds the wash water pumped by the pump, and is provided between rear panels of the fixed drum and the rotary drum. The storing unit guides the wash water to the rear panel of the rotary drum. The spraying unit is provided at the rear panel of the rotary drum, and sprays the wash water contained in the storing unit into the rotary drum.

Abstract: A washing machine which includes the outer casing having a box-shaped body to define a frame thereof and upper and lower plates. The upper plate is mounted to an upper portion of the body, and the lower plate is mounted to a lower portion of the body. The lower plate is integrated with a lower reinforcing plate to reinforce the strength of a lower portion of a rear surface of the body. The washing machine of the present invention reduces a number of parts, thus allowing the outer casing to be easily manufactured and enhancing productivity. Further, the washing machine allows the lower plate and the lower reinforcing plate to be made of a thin steel plate when the outer casing is manufactured, thus reducing manufacturing costs of the outer casing.

Abstract: A drum washing machine with a washing water circulation unit adapted to completely dissolve detergent supplied together with washing water and to enhance washing efficiency. During a washing operation, the washing water contained in a fixed drum is raised or drawn to a center portion of a rear panel of a rotatable drum by turning force of the rotatable drum and then sprayed into the rotatable drum through a nozzle. The circulated washing water accelerates the dissolution of the detergent, and the sprayed washing water directly impinges on laundry, thereby shortening the amount of time required to wet the laundry with the washing water. Therefore, the washing efficiency of the drum washing machine can be remarkably enhanced using only a small quantity of the washing water.
