  • Patent number: 10045680
    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.

  • Patent number: 9980625
    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.

  • Patent number: 9782052
    Abstract: A nozzle assembly and a dishwasher having the same. The dishwasher includes a main body, a wash tub, and at least one first nozzle assembly to wash the objects received in the wash tub. The first nozzle assembly includes a main nozzle configured to be rotatable about a rotation axis thereof, plural injection holes, a first flow path defined in the main nozzle for movement of wash water to be sprayed out toward the objects, a sub nozzle provided at the main nozzle, the sub nozzle internally defining a second flow path for movement of wash water to be sprayed out in a radial direction of the main nozzle, and a valve coupled to the main nozzle to open or close the second flow path. Providing the nozzle assembly with the first and second flow paths independent of each other may reduce noise due to collision of wash water.

  • Patent number: 9706896
    Abstract: A dishwasher having a spray unit fixed at a washing tub and configured to spray wash water, and a conversion assembly provided as to convert the direction of the wash water being sprayed from the spray unit toward a tableware basket. The conversion assembly includes a vane rotatably provided while disposed as to face with respect to the spray unit such that the direction of the converted wash water is adjusted. Through the structure as such, the spraying range of the wash water is extended, and may be able to minimize noise from the striking of the wash water against an inside wall or door of the dishwasher.
