  • An air inflow fan 8 is arranged in the air inflow pipe 7.
  • the siphon device is arranged to be capable of discharging water in the water inflow pipe when the drum washing machine executes a ventilation program, so that the water inflow pipe is communicated with the outside. After 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 level in the siphon device will rise under the action of air pressure after the air enters the water inflow pipe, until the siphon device is triggered to siphon.
  • the siphon device can discharge the water in the water inflow pipe, 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.
  • 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 water inflow pipe is a U-shaped water inflow pipe 6
  • the siphon device is a siphon pipe 9
  • a siphon trigger position of the siphon pipe 9 is located between the height position of the inlet of the U-shaped water inflow pipe 6 and the height position of the outlet of the U-shaped water inflow pipe 6.
  • the water level in the U-shaped water inflow pipe 6 continuously rises, and the water enters the outer cylinder 2 through the outlet of the U-shaped water inflow pipe 6.
  • the siphon trigger position of the siphon pipe 9 is higher than the outlet of the U-shaped water inflow pipe 6. Due to the principle of communicating vessel, the water in the U-shaped water inflow pipe 6 can only enter the outer cylinder 2 without causing the siphon pipe 9 to be triggered to siphon; after water injection is completed, water is stored in the U-shaped water inflow pipe 6 and completely seals a horizontal section and at least part of a vertical section of the U-shaped water inflow pipe 6, that is, the U-shaped water inflow pipe 6 is water sealed (as shown in FIG. 3 ).
  • the air inflow fan 8 When the drum washing machine executes the ventilation program, the air inflow fan 8 is turned on, and the outside air is introduced into the air inflow pipe 7 by the air inflow fan 8; then the air enters the outer cylinder 2.
  • the air in the outer cylinder 2 will enter the U-shaped water inflow pipe 6 through the outlet of the U-shaped water inflow pipe 6, and then under the action of air pressure, a downward pressure is applied to the water in the U-shaped water inflow pipe 6 so that the water level in the siphon pipe 9 rises (as shown in FIG. 4 ) until the siphon trigger position is reached.
  • the siphon pipe 9 discharges the water in the U-shaped water inflow pipe 6, so that the water seal in the U-shaped water inflow pipe 6 is released, thus enabling the air to enter the clothing treatment agent dispenser 5 through the inlet of the U-shaped water inflow pipe 6, and further be discharged to the outside (as shown in FIG. 5 ). Moreover, since the siphon trigger position of the siphon pipe 9 is lower than the inlet of the U-shaped water inflow pipe 6, the water in the U-shaped water inflow pipe 6 will not enter the clothing treatment agent dispenser 5, and therefore the drum washing machine will not be subject to overflow.
  • the U-shaped water inflow pipe 6 can also be replaced by a V-shaped water inflow pipe and other structures.
  • the siphon pipe 9 is communicated with the bottom of the horizontal section of the U-shaped water inflow pipe 6.
  • the air inflow pipe 7 can be communicated with the outer cylinder 2, and can also be communicated with a wrinkle part of the window gasket 4. Of course, it is most preferred that the air inflow pipe 7 is communicated with the wrinkle part of the window gasket 4.
  • the outside air can first enter the wrinkle part of the window gasket 4 before entering the outer cylinder 2, and can air-dry the wrinkle part of the window gasket 4 and the outer cylinder 2 at the same time, so that the interior of the cylinder assembly is air-dried with no dead corner, thus avoiding bacteria breeding inside the cylinder assembly.
  • 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.
  • a foam overflow prevention member 10 is arranged in the air inflow pipe 7, and the foam overflow prevention member 10 can be a one-way valve or a combined structure of dampers.
  • the foam overflow prevention member 10 includes a door, a first permanent magnet and a second permanent magnet.

  • the foam overflow prevention member 10 includes a door, a first permanent magnet and a second permanent magnet. The door is rotatably arranged in the air inflow pipe, the first permanent magnet is arranged on the door, and the second permanent magnet is arranged on a downstream side of the door in the air flow direction of the air inflow pipe.
  • 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.
  • the air inflow fan 8 enables the door to open the air inflow pipe 7 against a torsional force of the elastic torsional spring. After the air inflow fan 8 is turned off, the elastic torsional spring resets the door to close the air inflow pipe 7.
  • the air inflow fan 8 is arranged on the upstream side of the foam overflow prevention member 10 in the air inflow direction of the air inflow pipe 7. Through such an arrangement, the air inflow fan 8 will not contact the foam to cause short circuit, thus improving the safety of the drum washing machine.
  • the air inflow pipe 7 is provided therein with an air filtering member.
  • the air filtering member can be of a structure of a single-stage filter screen or a multi-stage filter screen, or be of other filtering structures, so as to prevent external dirt from entering the outer cylinder 2.
