The drainage chamber's water inlet 31 communicates with the sewage outlet 12 via a drainage conduit 21, while the drainage chamber's water outlet 32 ​​connects to the terminal drain pipe 50.

[0031] Specifically, the drainage pump 20 is a centrifugal pump, the impeller is a centrifugal impeller, the drainage portion 11 serves as a pump casing, and the sewage outlet 12 is located at the periphery of the impeller of the drainage pump 20 .

[0032] Under the centrifugal action of the drainage pump 20, the sewage in the water cup 10 can be discharged from the drainage part 11 and the water in the water cup 10, discharged into the drainage conduit 21 from the drainage port 12, and then flows through the drainage cavity of the respirator 30, and finally discharged from the terminal drainage pipe 50.

[0033] Furthermore, in order to drain the residual water at the bottom of the inner tank, a first self-priming pump 40 can be used in addition to the above-mentioned drainage waterway to actively drain the residual water in the inner tank.

[0034] Reference Figure 2 、 Figure 5 As shown, a residual water drain outlet 13 is opened at the lower part of the drain part 11. The residual water drain outlet 13 is located at the lowest point of the inner cavity of the water cup 10 and the inner cavity of the drain part 11, so that the water in the water cup 10 and the drain part 11 can automatically flow downward to the residual water drain outlet 13.

[0035] The dishwasher's drainage circuit also includes a first self-priming pump 40. The water inlet of the first self-priming pump 40 is connected to the residual water drain port 13 via a first water conduit 41, and the water outlet of the first self-priming pump 40 is connected to the drainage chamber water inlet 2 35 via a second water conduit 42. After drainage is completed, the first self-priming pump 40 can replenish the drainage of the dishwasher. The residual water in the water cup 10 at the bottom of the inner tank can be actively sucked into the first self-priming pump 40, and then sent from the water outlet of the first self-priming pump 40 to the drainage chamber of the respirator 30, thereby draining the residual water at the bottom of the dishwasher's inner tank. Preferably, the first self-priming pump 40 can be a self-priming diaphragm pump, or a pump of a certain type that can achieve active self-priming drainage.

[0036] In this embodiment, the water cup 10, the breather 30, the water softener 100 and the second self-priming pump 110 constitute the water inlet channel of the dishwasher, which is used to supply water to the inner tank of the dishwasher.

[0037] The respirator 30 has a water inlet chamber, which is connected to a water inlet port 33 and a water outlet port 34.
