[0073] In a specific implementation, the dishwasher further includes a drainage pump, which discharges the washing water in the water cup component through the drainage pipe 100 .

[0074] At present, the working status of small tabletop dishwashers on the market is mainly divided into the following stages: drainage-water inlet-washing-drying. The washing stage of the dishwasher is the main stage of the dishwasher, which can be specifically divided into: drainage-water inlet-washing. When the dishwasher works normally, this stage will cycle three times. The preparation stage of the dishwasher is mainly about water intake. There is a flow valve on the water inlet pipe 90 of the dishwasher. When the water volume reaches a predetermined value, the dishwasher starts washing. A large amount of water will be sprayed on the tableware through the upper spray arm 60 and the lower spray arm 70 of the inner tank under the action of the washing pump, and then the peeled residue and the washing water flow to the drainage channel 10 together; after entering the drainage channel 10, the two layers of filter elements in the drainage channel 10 play a role, the upper filter element can intercept most of the residue, and the lower filter element can also intercept a small part of the residue. At this time, the upper filter element can be pulled out, the residue can be poured out, and the cleaning can be done; during this process, the dishwasher can continue to work, and the lower filter element can ensure that there are no large particles of residue at the bottom of the drainage channel; after the upper filter element is cleaned, it is put back into the drainage channel, and the lower filter element can be pulled out, the residue can be poured out, and the cleaning can continue, and it can also be put back after cleaning. The filter element can ensure that the sewage at the bottom of the drainage channel will not be blocked when passing through the drainage pump or the washing pump, causing damage to the water pump.

[0075] Specifically, after the tableware is rinsed for the last time, most of the large particles of residue are basically peeled off, and then the dishwasher drains the sewage and continues to take in water. After the dishwasher is finished taking in water, the washing pump will work again. At this time, the dishwasher enters the cycle washing stage. There are fewer residues in this stage, and the two layers of filters can play their corresponding roles, and the number of times the filter is dumped will be reduced; the dishwasher will repeat the above stages 3 times. Then, the dishwasher enters the drying stage. Under the action of the fan, the hot air will gradually dry the tableware. At this time, both layers of filters need to be pulled out for cleaning, and then put back after cleaning. This can remove the odor of the residue and extend the storage time of the tableware. The above drainage channel structure is adopted to solve the residue problem of the dishwasher well, and the filter dumping residue is convenient and released less frequently. At the same time, it also improves the washing efficiency of the dishwasher and ensures the washing quality of the dishwasher. Compared with other dishwashers on the market, this residue discharge structure is low in cost and convenient for residue discharge.

[0076] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0077] The drainage component of the present invention comprises a drainage channel 10, at least two filters 30 and at least two sealing doors 40.
