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 dishwasher including a washing tub having a bottom plate having an opening, a nozzle having a spraying hole configured to spray water, the nozzle passing through the opening, and a sealing member configured to seal the opening. The bottom plate includes a base portion on which the nozzle is installed, and a protruding portion extending downward from the base portion to form the opening, the nozzle includes a support portion on the base portion, and a nozzle side portion facing the protruding portion. A part of the support portion contacts the base portion and another part of the support portion is spaced apart from the base portion according to an inclination of the base portion, where the sealing member is disposed between the protruding portion and the nozzle side portion. The spraying trajectory of the water can thus be kept constant despite the inclination deviation of the base portion.

Abstract: Provided are a dish washing machine capable of effectively removing garbage which remains at the bottom of a washing tub and a filter and a method of controlling the same. When washing water is sprayed from a nozzle while a vane is positioned at a reference position during a drainage operation, since a deflection angle of the vane is bent back and the washing water is strongly sprayed toward a rear wall of a washing tub, the washing water may form a fast and strong water current over a bottom plate of the washing tub, and the fast and strong water current may remove garbage which remains at a filter while flowing over the bottom of the washing tub. Also, even when an excessive amount of garbage is accumulated at a filter at a top end of a sump and blocks the filter during a washing operation such as preliminary washing, main washing, etc., the filter is automatically washed using a small amount of water, thereby eliminating inconvenience of a user to directly separate and wash the filter.
