DISH WASHER AND METHOD FOR CONTROLLING SAME

摘要

Provided are a dish washer and a method for controlling same so as to remove filth remaining in a bottom and a filter of a washing tub. When a washing water is injected from a nozzle while a vane is positioned in a reference position during a draining cycle, the reflection angle of the vane is tilted backward, and the washing water is injected strongly to the rear wall of the washing tub so that the washing water is formed as a fast and strong water flow along the bottom plate of the washing tub, and as the fast and strong water flow flows along the bottom plate of the washing tub, filth remaining on the bottom plate, especially on the filter, of the washing tub can be removed. In addition, a small amount of water is used to wash the filter automatically, even in a case that an excessive amount of filth is stacked in a filter of an upper end of a sump blocking the filter during a washing cycle such as a pre-washing and a main washing; and a washing performance can be improved efficiently by determining accurately whether filter blocking or bubble generation is a cause of problems for lowered washing performance due to rough circulation of the washing water.
