When the water flows into the washing tub 111 to meet the washing requirement, the spray pump 153 and the water inlet valve 167 are both closed to close the washing water path, and the dishwasher 10 starts the dish washing operation.

By providing the spray pump 153, the water inlet valve 157, the drain valve 167 and the drain pump, the on/off of the washing water path can be controlled to prevent the washing water from flowing out of the first drain port 117 and the second drain port 118 to cause waste of the washing water flow in the process of injecting the washing water into the washing tub 111.

In some embodiments, when the first wash water path is opened, the spray pump 153 and the blowdown pump are activated, the water inlet valve 157 is opened, and when the second wash water path is opened, the spray pump 153 is activated, the water inlet valve 157 and the blowdown valve 167 are opened.

When the filter element 140 needs to be cleaned, the spray pump 153 and the sewage pump are started, the water inlet valve 157 is opened, the cleaning water flows through the spray pump 153, the water inlet pipe 155 and the filter cavity 141, and washes the inner cavity wall of the filter element 140, and then the residue adhered to the inner cavity wall of the filter element 140 is mixed with the cleaning water flow to form cleaning sewage, and the cleaning sewage flows out of the water collecting tank 115 and is discharged to the outside of the dishwasher 10 under the action of the sewage pump. Meanwhile, the cleaning water flow can dredge the filtering hole from the inner side of the filtering piece 140, and flow into the space between the wall of the filtering slot 113 and the filtering piece 140 through the filtering hole, so as to wash the outer side cavity wall of the filtering piece 140, and then the residue adhered to the outer side cavity wall of the filtering piece 140 is mixed with the cleaning water flow to form cleaning sewage, and is discharged out of the dishwasher 10 through the sewage discharge pipe 163.

In addition, the spraying pump 153, the water inlet pipe 155, the sewage pump, the sewage pipe, the water inlet valve 157 and the sewage valve 167 are matched to control the on-off of different water paths, and the requirements of the dishwasher 10 on different functions can be met.

It should be noted that in this particular embodiment, the dishwasher 10 also includes three sewerage circuits. The washing tank 111, the plane filter plate 130, the filter tank 113, the filter holes, the filter cavity 141, the water collecting tank 115, the first sewage draining port 117 and the sewage pump form a first sewage draining path together; the washing tank 111, the plane filter plate 130, the filter tank 113, the second sewage draining outlet 117 and the sewage draining pipe form a second sewage draining waterway together; the washing tub 111, the soil discharge passage 121, the filter chamber 141, the water collecting tub 115, the first soil discharge port 117, and the soil discharge pump together form a third soil discharge water path. The washing sewage after the washing of the bowls is finished can be discharged through any one or two or three sewage discharge water paths.

In addition, it is worth mentioning that, because the lifting cup 120 and the filtering member 140 are both hollow structures, when the washing wastewater in the washing tank 111 directly enters the water collecting tank 115 through the sewage discharge channel 121 and the filtering cavity 141 of the lifting cup 120, the particle size of the residue carried in the washing wastewater is large, and if the first sewage discharge member 161 does not have a large pressure capable of drawing and discharging the residue in the sewage discharge process, the residue may be accumulated in the water collecting tank 115 to block the water collecting tank 115. In this embodiment, since the first drainage member 161 is a drainage pump, the drainage pump can draw the sewage and the residue to the outside under a larger pressure, so as to ensure a better cleaning effect of the filter member 140. Since the residue flowing between the wall of the filter tank 113 and the filter member 140 is filtered by the flat filter plate 130, the residue at this position has a smaller particle size and is less difficult to discharge. The residue can be directly discharged to the outside of the dishwasher 10 through the drain pipe with the washing sewage carried. Compared with a sewage pump, the sewage discharge pipe occupies a smaller volume and has lower cost. Therefore, by arranging the drain pipe, the manufacturing cost of the dishwasher 10 can be effectively reduced under the condition that the requirement of draining outside the filtering piece 140 is met, and the miniaturization of the dishwasher 10 is convenient to realize. Alternatively, the drainage pipe may be a single drainage pipe, or a plurality of sub drainage pipes 1632 may be connected end to end in sequence and communicated with each other.

In some embodiments, the drain assembly 160 further includes a manifold 165, and each of the first drain member 161 and the second drain member 163 communicates with the outside through the manifold 165. Specifically, the sewage pump has a sewage discharge end and a collecting end, the sewage discharge end is communicated with the first sewage discharge port 117, the collecting end is communicated with the collecting pipe 165, and residues on the inner side cavity wall of the filter member 140 can be discharged to the outside through the collecting pipe 165. And the two opposite ends of the drainage pipe are respectively communicated with the second drainage port 118 and the manifold 165, so that the residue on the outer side cavity wall of the filter member 140 can be discharged to the outside through the manifold 165.

Through setting up collecting pipe 165, can converge the sewage that flows through dredge pump and blow off pipe the back and discharge from same pipeline, consequently, at the in-process of installation dish washer 10, only externally install one can with collecting pipe 165 intercommunication and be used for receiving wash sewage and wash the structure of sewage can to in order to simplify dish washer 10's the installation degree of difficulty.

In some embodiments, the bottom of the filter tank 113 protrudes to form a water blocking rib 119, and the water blocking rib 119 is used for blocking the sewage flowing into the filter tank 113 in the filter tank 113.

In order to prevent the washing sewage flowing into the filter tank 113 from the washing tank 111 or the washing sewage flowing into the filter tank 113 from the filter cavity 141 through the filter holes from overflowing to other positions of the base 110 to pollute the internal structure of the dishwasher 10, the bottom of the filter tank 113 is further provided with a water blocking rib 119, and the water blocking rib 119 can block the washing sewage or the washing sewage between the outer side of the filter element 140 and the wall of the filter tank 113 in the filter tank 113, and ensure that the washing sewage or the washing sewage is effectively discharged from the second sewage discharge outlet 118, thereby effectively improving the cleaning reliability of the filter element 140.

In some embodiments, the spray member 151 includes a hollow spray main body 1512 and a plurality of spray arms 1514, the plurality of spray arms 1514 are disposed at intervals along a circumferential direction of the spray main body 1512 and are communicated with the spray main body 1512, the spray main body 1512 is communicated with the water inlet pipe 155, and the spray arms 1514 are provided with spray holes 1516.
