In the utility model, the height of the waterway top plate 4 from the inner tank bottom plate 3 is 96mm.

On the top surface of the waterway roof 4, a sprinkler mounting seat 5 is fixed, and the sprinkler system 7 is sealed and fixed on the waterway roof 4 through the sprinkler mounting base 5, and the installation surface of the spraying system 7 and the waterway roof 4 is set. There is a sealing ring to prevent the washing water from overflowing. The sprinkler system 7 has a built-in diversion pipe, one end of the diversion pipe is connected to the water jet outlet of the sprinkler system 7, and the other end passes through the center of the sprinkler mounting base 5 and the waterway roof 4, and then connects with the water circulation system 1 fixedly installed under the waterway roof 4 In communication, the washing water in the water circulation system 1 is introduced into the spray system 7 and sprayed out. According to needs, multiple sprinkler mounting bases 5 and sprinkler systems 7 can be provided. In the utility model, the top surface of the spraying system 7 is a plane, and the height of the top surface from the inner tank bottom plate 3 is not much 130mm, which is 125mm in the utility model.

The water circulation system 1 is integrally detachably installed on the inner tank bottom plate 3, which facilitates installation and maintenance, reduces the operating space reserved for installation, and reduces the volume of the sealed space 6. From the perspective of height, the waterway can be fully reduced. The distance between the top plate 4 and the inner container bottom plate 3 realizes that the height of the waterway top plate 4 from the inner container bottom plate 3 is not more than 100mm, thereby reducing the overall height of the dishwasher. The water circulation system 1 is sealed and connected with the bottom plate 3 of the inner tank and the side wall 2 of the inner tank as a whole, and the seal between the waterway roof 4 and the sidewall 2 of the inner tank is realized by the sealing strip 8, so that the waterway system with frequent water leakage and the waterway roof 4 The washing water will not enter other parts in the sealed space 6 through the installation gap between the waterway top plate 4 and the inner tank side wall 2, and will not affect or even damage other parts during the operation of the dishwasher.

The water circulation system 1 is a layered waterway system as shown in Figure 2, comprising at least two waterway installation plates, a water tank 9 for water storage, and a layered waterway structure between the two waterway installation plates.
