When the circulating water pump 31 is operated, the water in the water tank 11 is pumped into the water spraying device 34 by the circulating water pump 31, and water is sprayed to the dishes through the water spraying nozzles, so that the circular washing is realized.

As shown in fig. 11, the drain assembly 1 includes a sump 11, a first pipe 12, a drain pump 13, a drain pipe 132, and a blocking structure 14. The tank 11 is a collection device for the liquid (e.g., water) used for washing. The drain pump 13 serves to discharge the liquid collected in the sump 11 to the outside. Both ends of the first pipeline 12 communicate with the water tank 11 and the drain pump 13, respectively, to communicate the water tank 11 with the drain pump 13. The first pipe 12 is provided with a blocking structure 14, and the blocking structure 14 can conduct or block the first pipe 12.

Specifically, the first pipeline 12 includes a first pipe segment 121, a resistance pipe segment 123, and a second pipe segment 122. One end of the first pipe segment 121 is communicated with a position on the side wall of the water tank 11 near the bottom wall, and the other end of the first pipe segment 121 is communicated with the resistance pipe segment 123. One end of the second pipe section 122 is communicated with the drain pump 13, and the other end of the second pipe section 122 is communicated with one end of the resistance pipe section 123 far away from the first pipe section 121. The resistance pipe section 123 comprises an elbow structure 1231 and a connecting pipe 1232, wherein the elbow structure 1231 is located on one side of the first pipe section 121 close to the opening of the water tank 11 and arches towards the opening side of the water tank 11; the two ends of the elbow structure 1231 are respectively connected to a connecting pipe 1232, and the two connecting pipes 1232 are respectively connected to the first pipe segment 121 and the second pipe segment 122. The elbow structure 1231 and the two connecting pipes 1232 form an inverted V-shaped structure to further increase the height difference between the elbow structure 1231 and the first pipe segment 121 through the connecting pipes 1232. The blocking structure 14 is disposed in the elbow structure 1231 and is movably connected to the wall of the first pipeline 12. The connecting pipe 1232 may have a straight pipe structure or a pipe section structure with other shapes. The water inlet of the drain pump 13 is in communication with the first conduit 12 and the water outlet of the drain pump 13 is in communication with the drain conduit 132. Wherein an end of the drain line 132 remote from the drain pump 13 extends outside the housing 2 to facilitate outward drainage.

When the drainage pump 13 is operated, a negative pressure can be generated in a portion of the first pipeline 12 between the blocking structure 14 and the water inlet of the drainage pump 13 under the action of the drainage pump 13, so that a pressure difference is generated between two ends of the blocking structure 14, and the blocking structure 14 moves relative to the pipe wall of the first pipeline 12 under the action of the pressure, thereby conducting the first pipeline 12. When the first pipeline 12 is in a conducting state, the liquid in the water tank 11 is discharged outwards under the action of the drainage pump 13; when the first pipeline 12 is in the blocking state, the blocking structure 14 blocks the liquid or air in the first pipeline 12 to reduce the air in the water tank 11 flowing into the drainage pump 13, so as to reduce the noise generated by internal gas-liquid mixing during the operation of the drainage pump 13, and simultaneously, the height difference between the bent pipe structure 1231 and the first pipe section 121 is utilized to prevent the residual liquid in the water tank 11 from contacting with the blocking structure 14 after the drainage is finished.

When the dish washing apparatus is in the circulation washing state, the drain pump 13 is in the stop state, the blocking structure 14 blocks the first pipeline 12, and the circulation water pump 31 operates to circularly wash the dishes. After the tableware cleaning device finishes cleaning, the tableware cleaning device enters a drainage state, the circulating water pump 31 is stopped, and the drainage pump 13 is started to run, so that outward drainage is realized.

Fig. 12 shows another implementation of resistance tube segment 123 in this embodiment. The resistance pipe section 123 comprises an elbow structure 1231 and a connecting pipe 1232, wherein the elbow structure 1231 is positioned on one side of the first pipe section 121 close to the opening of the water tank 11 and arches towards the opening side of the water tank 11; one end of the elbow structure 1231 is in communication with the first tube segment 121 via a connecting tube 1232, and the other end of the elbow structure 1231 is in direct communication with the second tube segment 122. The blocking structure 14 is disposed in the bent pipe structure 1231, and after the drain assembly 1 is assembled, the bent pipe structure 1231 and the blocking structure 14 have a height greater than that of the first pipe segment 121.

Above combine the figure to explain in detail the technical scheme of the utility model, can effectively reduce the air volume that flows in the drain pump to there is the phenomenon of noise because of inside gas-liquid mixture in the time of alleviating the drain pump operation, simultaneously, drainage component's simple structure need not to install check out test set additional, is favorable to control cost.
