The invention relates to a dishwasher comprising a water cup, a drainage
system, and a rinse
system and a circulation
filter system, which are communicated with the water cup, wherein a rinse
pump chamber and a circulation
pump chamber, which are independent from each other, are arranged in the dishwasher, a rinse pump is arranged in the rinse
pump chamber, a
filtration device is arranged on the water cup, the water inlet of the rinse pump chamber is communicated with the water cup, and the water outlet is connected with a sprinkling device of the rinse
system; and a circulation pump is arranged in the circulation pump chamber, the water inlet of the circulation pump chamber is communicated with the water cup, a filter screen and
slag cuter blades are arranged at the water inlet, the water outlet of the circulation pump chamber is communicated with a circulation filter chamber, the upper part of the circulation filter chamber is provided with a circulation filter screen, and the lower part of the circulation filter chamber is provided with a
slag discharge opening communicated with a drainage system. The dishwasher of the invention uses the independent circulation pump to provide water for a circulation filter, so that food residues can be filtered, circulation water and tableware can be prevented from suffering secondary
pollution, and the flow rate and the
hydraulic pressure of rinsing water can not be weakened; and therefore the cleaning efficiency of the dishwasher is increased, and water and
energy consumption is reduced.
