In this embodiment, the outer tub 2 is connected with a drain pipe 4 for discharging washing water, and the other end of the drain pipe 4 extends to the outside of the machine body 1. When the washing machine executes the dewatering procedure, the water drain pipe 4 connected with the outer cylinder 2 is opened, and the air flow blown into the outer cylinder 2 from the outside of the machine body 1 is at least partially discharged from the water drain pipe 4, so that the dewatering water flow separated from the load is discharged from the water drain pipe 4. Preferably, in order to increase the exhaust rate of the tub 2, the exhaust duct 13 communicating with the tub 2 may be opened to allow the air flow portion flowing out of the tub to flow out of the exhaust duct when the washing machine performs the dehydration process.
In this embodiment, when the washing machine starts the dewatering process, the air flow is blown into the outer tub 2, so that the circulating air flow is blown at intervals during the whole running period of the dewatering process, and thus, the maximum efficiency is ensured that too much foam is not generated in the outer tub 2.
