Specifically, the wrapped-around tube housing of the fan assembly 8 is connected to the first valve port 51 through the ventilation hose 62, the drain inlet 4 is connected to the second valve port 52 through the connection hose 46, and the drain tube 92 may be directly connected to the third valve port 53.

The main differences between this embodiment and the first embodiment are: the three-way valve is used for replacing the two original plunger type electromagnetic valves. The three-way valve can realize three valve positions to conduct any two valve ports, wherein when the second valve port 52 and the third valve port 53 of the three-way valve are conducted, the drainage and air inlet pipeline 4 is communicated with the drainage pipe 92, so that the drainage function can be realized; when the first valve port 51 and the second valve port 52 of the three-way valve are communicated, the drainage air inlet pipeline 4 is communicated with the ventilation hose 62, so that the drying function can be realized; when the first valve port 51 and the third valve port 53 of the three-way valve are conducted, the second valve port 52 can be blocked, the normal washing function is realized, and the air inlet pipeline can be provided with an air inlet control valve to prevent water in the drainage pipeline from flowing back into the air inlet pipeline to influence the work of the fan assembly 8.

Optionally, the three-way control valve is an electric three-way valve, which can be customized as desired.

Example three:

In this embodiment, as shown in fig. 17-19, the bottom wall of the lower cup is provided with a drainage pipe 91 communicated with the cavity, the drainage pipe is provided with a drainage hole, a drainage control valve 72 for opening and closing the drainage hole is arranged in the drainage pipe, the side wall of the lower cup is provided with an air inlet pipe 90 communicated with the cavity, the air inlet pipe is provided with an air inlet hole, and an air inlet control valve for opening and closing the air inlet hole is arranged in the air inlet pipe.

In this embodiment, the drainage pipeline 91 is independent of the air inlet pipeline 90, air inlet and water outlet are realized through different passages respectively, each pipeline is controlled respectively, and flexibility of machine control is improved.

The main differences between this embodiment and the first embodiment are: the drain pipe 91 is disposed separately from the inlet pipe 90, wherein the drain pipe 91 is located at the same position as the drain inlet pipe in the first embodiment, and the inlet pipe 90 is provided on the side wall of the lower cup 3.

Optionally, a drainage port 911 is provided on the drainage pipeline 91, the drainage port 911 is communicated with a sewer pipe through a drainage pipe, an air inlet port 614 is provided on the air inlet pipeline 90, and the air inlet port 614 is communicated with the fan assembly through a ventilation hose.

Compared with the first embodiment, the dishwasher of the embodiment can flexibly place the position of the air inlet pipeline.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, i.e. all equivalent changes and modifications made according to the present invention are covered by the scope of the claims of the present invention, which is not illustrated herein.
