The inner container 8 can prevent washing water from flowing into the exhaust section 3-4 from the inlet of the exhaust section 3-4 beyond the inlet of the return air section 3-3 during washing, so as to keep the inner circulation in the inner container 8 and the outer circulation outside the inner container 8 relatively stable.

Referring to fig. 4, in the present embodiment, the return air section 3-3 is provided with a heating member 34 capable of heating the low-humidity gas flowing through the return air section 3-3 so that the drying effect of the low-humidity gas flowing back into the inner container 8 from the first gas outlet k1 is more excellent.

The mixed gas flows along the air duct 3, and when flowing through the inertial separation section 3-2, particularly the inertial separation bending part 3-2A, under the action of inertia, the mixed gas forms flowing water drops on the inner peripheral wall 32 corresponding to the outer bending of the inertial separation bending part 3-2A, and enters the water drainage channel 3A through the water removal port 32A, so that the water-vapor separation effect of the inertial separation section 3-2 on the mixed gas is formed. In the case where the moisture content of the hot and humid gas is large, the water droplets form a thin and flowing film of water on the inner peripheral wall 32, and can be continuously discharged from the water discharge port 32a into the water discharge passage 3A.

In the present embodiment, the drain 3A is communicated with the exhaust section 3-4, and water droplets entering the drain 3A through the dewatering port 32a finally flow into the exhaust section 3-4 and are discharged together with the high-humidity gas, so as to solve the problem of the treatment of separated water after the water-vapor separation. Because the exhaust section 3-4 is discharged outside the inner container 8, the moisture content in the inner container 8 can be gradually reduced under the continuous action of the air path circulation mechanism in the embodiment, which is beneficial to the overall inner environment drying effect and efficiency in the inner container 8.
