The residue flows back to the drain cavity 22 .

working principle:

When the dishwasher performs the washing process, the food residues are initially filtered by the flat filter 3 and then flow into the filter chamber 21 of the water cup 2 and are stored in the food residue collection chamber 42 of the filter 4. The inlet of the filter 4 is provided with a stop Rib 41, a funnel-shaped structure is formed between the retaining rib 41 and the retaining rib 41. Due to the blocking of the retaining rib 41, the food residue flowing into the food residue collection chamber 42 cannot flow out of the food residue collection chamber 42, thereby improving the filter 4 pair. Food scraps collection capability. At the same time, the water in the inner tank 1 passes through the filter screen 431 of the filter 4 and enters the washing device 7 along the circulating water outlet 43 and the water outlet 211 of the filter cavity 21 to perform water circulation washing, thereby realizing water recycling.
