The exhaust section 3-4 is located on the outer curved side of the closest inertial separation bending part 3-2A, and the return section 3-3 is located on the inner curved side of the closest inertial separation bending part 3-2A.

The water-steam separation device of the embodiment is applied to the inner container of the dish-washing machine, and has the main functions of dividing the gas which flows through the air duct 3 and has certain humidity into high-humidity gas and low-humidity gas, wherein the low-humidity gas can be used for drying bowls and chopsticks in the inner container of the dish-washing machine, and the high-humidity gas is discharged out of the inner container of the dish-washing machine. The gas flowing in the air duct 3 can generate a gradient in moisture content when flowing through the inertia separation bending part 3-2A, the moisture content of the gas which is closer to the outer bending part 3-2A is higher, the moisture content of the gas which is closer to the inner bending part 3-2A is lower, and the gas flows into the air return section 3-3 and the exhaust section 3-4 by utilizing the characteristic and according to the arrangement of the positions of the air return section 3-3 and the exhaust section 3-4, the moisture content of the part of the gas flowing into the air return section 3-3 is obviously lower than that of the part flowing into the exhaust section 3-4, namely, the split flow is formed, the low-moisture gas flows into the air return section 3-3, and the high-moisture gas flows into the exhaust section 3-4.

It should be noted that the low-humidity gas and the high-humidity gas in this embodiment are not limited to specific humidity of the two gases, but the humidity of the gas entering the return air section 3-3 is relatively lower than that of the gas entering the exhaust air section 3-4, and thus the two gases are respectively referred to as low-humidity gas and high-humidity gas.

In another embodiment, the top of the moisture condensation box 71 has two through openings, the gas discharge pipe 73 and the moisture discharge pipe 72 are respectively inserted into the two through openings, the inlet of the gas discharge pipe 73 and the outlet of the moisture discharge pipe 72 are lower than the corresponding through openings, a partition 711 is arranged in the moisture condensation box 71 and between the gas discharge pipe 73 and the moisture discharge pipe 72, and a circulation opening is formed between the partition 711 and the top of the moisture condensation box 71. The partition 711 divides the vapor condensation chamber into two chambers, and after the high-humidity gas discharged from the moisture discharge pipe 72 enters the bottom of one side chamber, the moisture thereof is gradually intercepted by the filter screen or the like, the high-humidity air with reduced moisture content enters the other side chamber through the flow port, and then enters the gas discharge pipe 73 from the bottom thereof and finally is discharged from the second gas outlet k2.
