Preliminary note: Some peers may suspect machine-translations for patents even in cases of European manufacturing location, but machine-translations for patents are normally marked accordingly. Patent applications in Europe may be machine-translated or not, in USA this would be strange.

The term "Wäschesperre" consist of two particles: “Wäsche” (laundry, lint, clothes, underwear) and “Sperre” (lock, locking, blockage, barrier).

Item 4 is shown in figures 1 -4 .

A removable filter assembly includes a perforate grid portion openly facing the interior of a tumbling chamber and effectively forming a portion of the stationary bulkhead engageable by the tumbling fabrics and further includes a fine mesh filter screen disposed in the path of air being drawn through the tumbling chamber. Lint and other particles removed from the airflow are collected on the fine mesh screen and trapped within the assembly between the perforate portion and the fine mesh screen which are removable from the bulkhead as a unit.
:
SUMMARY OF THE INVENTION It is an object of the instant invention to provide an improved filter assembly disposed in a stationary bulkhead and removable as a unit for efficient cleaning.

It is a further object of the instant invention to provide an improved filter assembly disposed in a stationary bulkhead and including a perforate housing portion forming a portion of the bulkhead openly facing the interior of the tumbling chamber and removable from the bulkhead.

It is still a further object of the instant invention to provide a bulkhead filter assembly including a housing defining a perforate portion cooperatively disposed in a stationary bulkhead openly facing the tumbling chamber for contact by tumbling articles therein and further including a perforate screen mounted on the filter housing for filtering lint from the airflow and retaining the lint within the filter assembly for removal from the dryer apparatus.

The instant invention achieves these objects in a drying apparatus having a stationary bulkhead at the front of the machine in which is positioned a bulkhead filter assembly having a housing effectively forming a portion of the bulkhead and defining a perforate portion openly facing the tumbling chamber. A filter screen, disposed adjacent to the perforate portion for filtering particles from the air and retaining the particles within the assembly, is removable from the apparatus with the housing.
:
The filter means 73 includes a lint filter screen 103 and peripheral frame 104 that generally mates with the recess 100 in the rearwardly extending flange 99 of filter housing 94 and is thus supportable by the housing 94 in the air duct 70. The filter means 73 is removably retained in the recess 100 of the peripheral flange 99 by a pair of downwardly extending tabs 105 engageable with openings in the filter housing flange 99 and by a detent 106 extending downwardly from the upper filter housing flange 99.
As previously indicated the filter assembly 69 is removable from its operative position by gripping the upper handle 101 and sliding the assembly 69 toward the center of the access opening 57 so that the filter assembly 69, including the filter housing 94 and the filter means 73, is removed from the dryer apparatus as a unit. The lint is collected on the side of the filter screen 103 interior to the filter assembly 69 so that upon removal of the filter assembly 69 from the drying apparatus, lint is effectively trapped within the assembly.

@ wakana M
Considering the different patents with figures, it should also be possible to circumscribe the function without translating this rare term. You will see, that most tumble driers have a similar device to prevent clothes, esp. small parts like underwear and lints to be swallowed by the vent outlet. The technical details may vary from manufacturer to manufacturer, but all have sieves, screens, filters, etc.
