For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

Based on the problem pointed out in the background art that the drum assembly of the existing drum washing machine is very humid after washing the clothes, which is easy to breed bacteria and produce peculiar smell, and cause secondary pollution to the clothes washed subsequently. The present invention provides a drum washing machine. The purpose is to make the drum washing machine have a ventilation function without changing the structure of the original drum washing machine as much as possible, so that after washing the clothes, the residual water inside the drum assembly can be air-dried to ensure that the drum assembly is dry and avoid breeding. Bacteria and odors are generated, and the user will not cause secondary pollution to the clothes when the user uses the drum washing machine to wash the clothes again, and there is no need to make major structural changes to the drum washing machine, the structure is simple, the production cost is saved, and the user experience is improved.

Specifically, as shown in FIGS. 1 and 2 , the front-loading washing machine of the present invention includes a case 1 and a tub assembly disposed in the case 1 , and the tub assembly includes an outer tub suspended in the case 1 through a plurality of elastic damping members 2. Rotate the inner cylinder 3 arranged in the outer cylinder 2 and the window pad 4 connected with the outer cylinder 2. The window pad 4 is also connected with the clothes feeding port of the box 1. The inner cylinder 3 is driven by a combination of a motor and a belt or Driven by a direct-drive motor, the door glass of the drum washing machine can be tightly fitted with the window pad 4 to achieve sealing when it is closed. The inlet of the water pipe is communicated with the clothes treatment agent feeding box 5, and the outlet of the water inlet pipe is communicated with the cylinder assembly. After the external water enters the clothes treatment agent feeding box 5, the clothes treatment agent and water are injected into the outer cylinder 2 through the water inlet pipe together. The laundry treatment agent feeding box 5 is in communication with the outside world, the height of the inlet of the water inlet pipe is higher than that of the outlet of the water inlet pipe, and the water inlet pipe is preferably communicated with the outer cylinder 2 . When the front-loading washing machine performs the washing procedure, firstly, water is injected into the outer tub 2 through the water inlet pipe until the washing water level is reached, and then the water inlet is stopped. At this time, there is still water in the water inlet pipe and a water seal is formed.

As shown in Figure 1, the drum washing machine of the present invention also includes an air inlet pipe 7 connecting the outside with the drum assembly and a siphon device connected with the water inlet pipe. The air inlet pipe 7 is provided with an air inlet fan 8, and the siphon device is arranged in When the front-loading washing machine performs the ventilation procedure, the water in the water inlet pipe can be discharged, so that the water inlet pipe can be communicated with the outside world. After the air inlet fan 8 is turned on, the outside air can be introduced into the outer cylinder 2 through the air inlet pipe 7, and the air in the outer cylinder 2 will enter the water inlet pipe. After entering the water inlet pipe, the water level in the siphon device will rise under the action of air pressure, until the siphon device is triggered to generate a siphon phenomenon. The air in the water can continue to enter the clothes treatment agent delivery box 5 after entering the water inlet pipe. Since the clothes treatment agent delivery box 5 is connected to the outside world, the outer cylinder 2 is in a conductive state with the outside world, and then in the air inlet. Under the action of the fan 8, ventilation is realized, so that the inside of the drum assembly is air-dried and the odor in the drum assembly is discharged, so as to avoid breeding of bacteria and secondary pollution to subsequent laundry washing.

Preferably, as shown in Figures 1 to 5, the water inlet pipe is a U-shaped water inlet pipe 6, the siphon device is a siphon pipe 9, and the siphon trigger position of the siphon pipe 9 is located at the height of the entrance of the U-shaped water inlet pipe 6 and the U-shaped water inlet pipe. 6 between the height positions of the exit. During normal washing of the drum washing machine, water is injected into the outer tub 2 first, and the external water (generally connected to tap water) enters the clothing treatment agent dispensing box 5 and then enters the U-shaped water inlet pipe 6 through the entrance of the U-shaped water inlet pipe 6. The water level in the U-shaped water inlet pipe 6 rises continuously and enters the outer cylinder 2 through the outlet of the U-shaped water inlet pipe 6. The siphon trigger position of the siphon pipe 9 is higher than the outlet of the U-shaped water inlet pipe 6. Due to the principle of the connector, the U-shaped water inlet The water in the water pipe 6 can only enter the outer cylinder 2 without causing the siphon 9 to trigger the siphon phenomenon, and after the water injection is completed, the U-shaped water inlet pipe 6 stores water and completely closes the transverse section of the U-shaped water inlet pipe 6 and at least A part of the vertical section is water-sealed for the U-shaped water inlet pipe 6 (as shown in Figure 3). When the drum washing machine executes the ventilation program, the air inlet fan 8 is turned on, and the outside air is introduced into the air inlet duct 7 by the air inlet fan 8, and then the air enters the outer cylinder 2, and the air in the outer cylinder 2 will pass through the U-shaped inlet. The outlet of the water pipe 6 enters the U-shaped water inlet pipe 6, and then exerts downward pressure on the water in the U-shaped water inlet pipe 6 under the action of air pressure, so that the water level in the siphon 9 rises (as shown in Figure 4), until When the siphon trigger position is reached, the siphon 9 discharges the water in the U-shaped water inlet pipe 6, so that the U-shaped water inlet pipe 6 is released from the water seal, and then the gas can enter the clothing treatment agent delivery box 5 through the inlet of the U-shaped water inlet pipe 6, and then discharge to the outside world (as shown in FIG. 5 ), and since the siphon trigger position of the siphon pipe 9 is lower than the entrance of the U-shaped water inlet pipe 6, the water in the U-shaped water inlet pipe 6 will not enter into the laundry treatment agent dispensing box 5, and thus will not be discharged. It will cause the front-loading washing machine to overflow. In the above, as an alternative, the U-shaped water inlet pipe 6 can also be replaced with a structure such as a V-shaped water inlet pipe. Those skilled in the art can flexibly set the shape and structure of the water inlet pipe according to the internal layout space of the drum washing machine in practical applications. The adjustment and change of the shape and structural style of the water inlet pipe do not constitute a limitation to the present invention, and should all be limited within the protection scope of the present invention. In a preferred situation, the siphon pipe 9 is communicated with the bottom of the transverse section of the U-shaped water inlet pipe 6, through such a setting, the water in the U-shaped water inlet pipe 6 can be completely emptied when the drum washing machine performs the ventilation procedure, Avoid residues.

In addition, the air inlet duct 7 can be communicated with the outer cylinder 2, and can also be communicated with the folded portion of the window pad 4. Of course, it is most preferable to communicate with the folded portion of the window pad 4. Through this arrangement, the outside air can first enter the The wrinkled part of the window pad 4 enters the outer cylinder 2 again, and the wrinkled part of the window pad 4 and the outer cylinder 2 can be air-dried at the same time, so that there is no dead space inside the cylinder assembly to air dry, avoid the breeding of bacteria inside the cylinder assembly, and do not require the user to repeatedly clean At the same time, it can avoid secondary pollution to the clothes washed subsequently. Further, when the air inlet pipe 7 is communicated with the outer cylinder 2, it is preferably communicated with the top of the outer cylinder 2 to prevent the water in the outer cylinder 2 from flowing back into the air inlet pipe 7 during washing. When the pleated part of 4 is connected, it is preferable to communicate with the top of the pleated part of the window pad 4, and it is also avoided that the water in the outer tub 2 flows back into the air inlet pipe 7 during washing.

Preferably, as shown in FIG. 1 , an anti-foam overflowing member 10 is provided in the air inlet duct 7 , and the anti-foaming overflowing member 10 may be a one-way valve or a combined structure of a damper. For example, the anti-foam overflow member 10 includes a door body, a first permanent magnet and a second permanent magnet, the door body is rotatably arranged in the air intake pipe, the first permanent magnet is arranged on the door body, and the second permanent magnet is arranged along the inlet of the air intake pipe. The wind direction is set on the upstream side of the door body, and the magnetic properties of the first permanent magnet and the second permanent magnet are different. When the intake fan 8 is turned on, the air flow generated by the intake fan 8 can overcome the first permanent magnet and the second permanent magnet. The suction between the magnets makes the door body rotate from the closed position to the open position, so that the outside air enters the outer cylinder 2. When the air inlet fan 8 stops, the door body passes through the connection between the first permanent magnet and the second permanent magnet. The suction between the two stays in the closed position, preventing the foam from overflowing. For another example, the anti-foam overflowing member 10 includes a door body, a first permanent magnet and a second permanent magnet, the door body is rotatably arranged in the air inlet pipe, the first permanent magnet is arranged on the door body, and the air flow of the second permanent magnet air inlet pipe is The direction is set on the downstream side of the door body, and the magnetic properties of the first permanent magnet and the second permanent magnet are the same. When the intake fan 8 is turned on, the air flow generated by the intake fan 8 can overcome the difference between the first permanent magnet and the second permanent magnet. The repulsive force between the two makes the door body rotate from the closed position to the open position, so that the outside air enters the outer cylinder 2. When the air intake fan 8 stops, the door body passes through the gap between the first permanent magnet and the second permanent magnet. The repulsive force remains in the closed position, preventing the foam from overflowing. Of course, the above-mentioned first permanent magnet and second permanent magnet can also be replaced with elastic torsion springs, that is, the door body is rotatably arranged in the air inlet duct 7 through the elastic torsion spring, and the opening of the air inlet fan 8 can make the door body overcome the elastic torsion The torsional force of the spring opens the air inlet duct 7 , and after the air inlet fan 8 is closed, the elastic torsion spring resets the door and closes the air inlet duct 7 . Those skilled in the art can flexibly set the specific structure of the anti-foam overflowing member 10 in practical applications. Such adjustments and changes to the specific structure of the anti-foaming overflowing member 10 do not constitute a limitation to the present invention, and should be limited to the protection of the present invention. within the range. In a preferred situation, along the air inlet direction of the air inlet duct 7, the air inlet fan 8 is arranged on the upstream side of the anti-foam overflowing member 10. Through this arrangement, the air inlet fan 8 will not come into contact with the foam and cause the occurrence of Short circuit situation, improve the safety of the drum washing machine.

Preferably, an air filter member is provided in the air inlet pipe 7, and the air filter member can adopt the structure of a single-stage filter screen or a multi-stage filter screen, or adopt other filter structures, so as to prevent external dirt from entering the outer cylinder 2. .
