Abstract: A washing machine including a washing tub capable of improving a washing effect and dehydration efficiency of the laundry is provided. The washing machine includes: a body; a washing tub configured to be rotatably provided in the body, accommodate a laundry therein, and have a cylindrical shape; a plurality of recessed portions configured to be formed in an inner circumferential surface of the washing tub and be arranged in the plural in a circumferential direction of the washing tub to form a pattern; and first dehydrating holes configured to be formed in the respective recessed portions, wherein the respective recessed portions are formed in a length direction of the washing tub.

Abstract: Disclosed herein is a dishwasher including a spray unit fixed to one sidewall of a wash tub and a reflecting plate assembly to reflect wash water sprayed from the spray unit onto dishes and to linearly reciprocate in a spray direction of the wash water sprayed from the spray unit. The dishwasher further includes a drive unit to drive the reflecting plate assembly, and a cam unit to transmit driving force of the drive unit to the reflecting plate assembly. The drive unit includes a motor to generate rotational force, and a belt forming a closed loop and caused to make cyclic movement by the motor. The cam unit is engaged with the belt to transmit power of the belt to the reflecting plate assembly. The cam is alternately engaged with first and second portions of the belt to cause the reflecting plate assembly to reciprocate.

Abstract: A dish washing machine is provided herein. The dish washing machine includes a switching assembly configured to change a direction of washing water sprayed by a spray unit. The switching assembly includes a switching unit configured to change the direction of the washing water. The switching assembly also includes a damping unit configured to lessen vibrations of the switching unit. Using this structure, the direction of the washing water is efficiently changed by the switching unit, and vibrations and noise are lessened.
