  • the air inflow fan 8 is turned on, the outside air can be introduced into the outer cylinder 2 through the air inflow pipe 7, and the air in the outer cylinder 2 will enter the water inflow pipe.
  • the water discharge pump 11 can discharge the water in the water inflow pipe through the water suction pipe 9, thus releasing the water seal in the water inflow pipe.
  • the air in the outer cylinder 2 can continue to enter the clothing treatment agent dispenser 5 after entering the water inflow pipe. Since the clothing treatment agent dispenser 5 is communicated with the outside, the interior of the outer cylinder 2 is communicated with the outside, so as to achieve ventilation under the action of the air inflow fan 8, so that the interior of the cylinder assembly is air-dried and the odor in the cylinder assembly is discharged at the same time, thus avoiding bacteria breeding and secondary pollution to subsequent clothing washing.

  • the air inflow pipe 7 when the air inflow pipe 7 is communicated with the outer cylinder 2, it is preferred that the air inflow pipe 7 is communicated with the top of the outer cylinder 2 to prevent the water in the outer cylinder 2 from flowing back into the air inflow pipe 7 during washing.
  • the air inflow pipe 7 is communicated with the wrinkle part of the window gasket 4, it is preferred that the air inflow pipe 7 is communicated with the top of the wrinkle part of the window gasket 4, which also prevents the water in the outer cylinder 2 from flowing back into the air inflow pipe 7 during washing.

  • the magnetic properties of the first permanent magnet and the second permanent magnet are the same.
  • an air flow generated by the air inflow fan 8 can overcome a repulsive force between the first permanent magnet and the second permanent magnet to make the door rotate from a closed position to an open position, so that the outside air enters the outer cylinder 2.
  • the air inflow fan 8 is turned off, the door is kept in the closed position through the repulsive force between the first permanent magnet and the second permanent magnet, so as to prevent foam from overflowing.
  • the first permanent magnet and the second permanent magnet described above can also be replaced by an elastic torsional spring, that is, the door is rotatably arranged in the air inflow pipe 7 through the elastic torsional spring.
