  • Patent number: 10244918
    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.
