The outer tub 52 is fixed and does not rotate, the door seal 3 is connected to the opening 521 of the outer tub 52, the inner side of the door seal 3 is provided with the inductive switch 4, the inductive switch 4 can be an electromagnetic inductive switch 4 or a photoelectric inductive switch 4, the inductive switch 4 is electrically connected with the control unit, and the inductive switch 4 is used for detecting whether clothes are exposed out of the door seal 3 or the outer tub 52.

Since the door seal 3 is filled with washing water during the washing process of the drum washing machine, and the rotation speed of the inner tub 51 is low during the washing process, even if the laundry is exposed out of the door seal 3 or the outer tub 52, the laundry is not abraded. And at drum type washing machine's dehydration stage, interior bucket 51 rotational speed is up to 1400 revolutions/mi n, and the fast-speed rotation of interior bucket 51 can cause wearing and tearing to the clothing that exposes door seal 3 or outer bucket 52, the utility model discloses a prevent that the clothing from causing wearing and tearing in the dehydration process and set up the fender clothing structure.

When the drum washing machine finishes washing clothes and enters a dehydration stage for dehydration, the inductive switch 4 is powered on and is in a working state. The inner tub 51 rotates, when the laundry rotates along with the inner tub, if no laundry is exposed out of the outer tub 52 or the door seal 3, the inductive switch 4 is not triggered, and at this time, the dehydration stage normally proceeds until the dehydration stage is finished.

When the laundry is dehydrated in the dehydration stage, when the laundry rotates along with the inner drum, if the laundry exposes out of the outer tub 52 or the door seal 3 and is caught on the door seal 3 at the opening 521 of the outer tub 52, the laundry will trigger the inductive switch 4, and the inductive switch 4 transmits a signal to the control unit, at this time, the inner tub 51 stops rotating, and the dehydration stops.

The control unit judges whether the number of times of entering the step of adjusting the barrier clothes reaches a preset number of times, wherein the preset number of times is 3. And when the times of the barrier adjusting stage do not reach the preset times, the control unit controls to enter the barrier adjusting stage.

In the step of adjusting the barrier: when the inductive switch 4 stops working, the control unit controls the traction motor 7 to pull and retract the traction wire 10, so that the end of the traction wire 10, far away from the opening 521, of the connecting rod 9 rotates around the rotating shaft 11 in a direction close to the traction motor 7, the end of the connecting rod 9, near the opening 521, abuts against the force receiving portion 131 of the blocking rib 13, moves from the side close to the traction motor 7 to the side far away from the traction motor 7 on the abutting surface 133 of the force receiving portion 131, and meanwhile, the end of the connecting rod 9, near the opening 521, constantly presses the force receiving portion 131 of the blocking rib 13 to drive the blocking rib 13 to move towards the inner side of the door seal 3 until when the end of the connecting rod 9, near the opening 521, abuts against the limiting block 134 of the force receiving portion 131, and the clothes blocking portion 132 of the blocking rib 13 at least partially extends out of the inner side of the door seal 3.

The inner tub 51 is operated clockwise at a low speed, and after the inner tub 51 is rotated for a predetermined time, the traction motor 7 releases the traction wire 10 to allow the elastic member 14 to apply an elastic force to the barrier rib 13 to reset the position of the barrier rib 13, that is, the elastic member 14 can apply an elastic force to the barrier rib 13 to reset the clothes blocking portion 132 of the barrier rib 13 back to the accommodating channel of the door seal 3. The preset time in this embodiment is 10 seconds.

The control unit controls the re-start of the induction switch 4 and simultaneously the inner tub 51 rotates, and detects whether laundry is exposed out of the door seal 3 or the outer tub 52 through the induction switch 4.

When the inductive switch 4 still detects that clothes are exposed out of the door seal 3 or the outer barrel 52, the control unit judges whether the times of entering the clothes blocking adjusting stage reach the preset times, and when the times of entering the clothes blocking adjusting stage do not reach the preset times, the control unit controls to enter the clothes blocking adjusting stage; when the times of the clothes blocking adjusting stage reach the preset times, the inductive switch 4 stops working, and the control unit controls the alarm on the drum washing machine to give an alarm, so that a user is reminded of needing to open the door cover 2 for manual intervention.

And detecting whether the manual intervention is finished or not, and controlling an alarm on the drum washing machine to alarm continuously by the control unit when the manual intervention is not finished. It may be provided that it is possible to detect whether the manual intervention is completed by detecting whether the user opens the door 2. When the manual intervention is completed, the control unit controls to start the inductive switch 4, and simultaneously the inner barrel 51 rotates, and whether clothes are exposed out of the door seal 3 or the outer barrel 52 is detected through the inductive switch 4.

When the inductive switch 4 still detects that the laundry is exposed from the door seal 3 or the outer tub 52, the above control process is repeated. When the inductive switch 4 does not detect that the clothes are exposed out of the door seal 3 or the outer tub 52, the dehydration stage is normally performed until the dehydration stage is finished.

In some embodiments, the inductive switch 4 may be replaced by a proximity switch, and the method for detecting whether the laundry is exposed from the door seal 3 or the outer tub 52 by the proximity switch is the same as the inductive switch 4, and will not be described herein.

The utility model discloses a traction motor 7 is received and is drawn traction wire 10, make traction wire 10 stimulate connecting rod 9 keep away from the one end of opening 521 and revolute 11 to the direction rotation that is close to traction motor 7, connecting rod 9 is close to opening 521's one end butt in the atress portion 131 that keeps off muscle 13, by one side that is close to traction motor 7 on the butt face 133 of atress portion 131 to one side of keeping away from traction motor 7 and remove, connecting rod 9 is close to opening 521's one end and extrudees constantly the atress portion 131 that keeps off muscle 13 with the inboard removal of keeping off clothing portion 132 to door seal 3 of ordering about fender muscle 13 simultaneously, keep off clothing portion 132 at least part and stretch out to the inboard of door seal 3 until keeping off muscle 13. When the inner tub 51 is rotated, the laundry exposed to the door seal 3 or the outer tub 52 may be rotated as the inner tub 51 is rotated, and when the laundry contacts the clothing blocking portion 132, the laundry may be guided by the obliquely extending clothing blocking portion 132 and withdrawn into the washing chamber 511, thereby solving the problem of laundry exposure.
