Definitions

• the invention relates to a loadable from the front laundry treating machine, preferably a washing machine, with a swinging in the device housing lye container and with a washing tub rotatable in the tub, with a material-elastic sleeve through which the tub is liquid-tightly connected to the edge of its front loading port to the housing side feed opening, and a door closing the housing side opening with a frusto-conical bulging towards the interior of the drum.
• truncated cone is to be understood below as a conical body with an arbitrary base surface with continuous arcs of arbitrary radii, eg, in addition to circular base surfaces also with oval, elliptical or egg-shaped base surfaces.
• the invention is described below with reference to a washing machine, but it can also find application in a laundry drying machine.
• the inwardly directed region of the filling body has a structure in the form of planar, raised elevations and depressions.
• this molded wavy or corrugated structure of the projecting into the laundry treatment space filling body of the entry of mechanics is to be reinforced in the laundry.
• the proposed shape does not have a positive effect, because the structure of the surface no repellent force component but acting in small areas of the fabric parts of the laundry flexing is done.
• the moving with the rotating drum laundry could also be trapped in the gap between the edge of the laundry drum and the cuff, which increases the risk of damage to the laundry to a special degree and the start of the drum during washing and spinning difficult or even prevent. This will also overburden the drive motor. Such dangers are particularly present when the drum is filled to its maximum capacity with laundry.
• laundry deflectors have been developed in addition to the filler as additional components.
• DE 103 59 01 1 B3 it is proposed to attach an annular elastic laundry deflector to the tub so that the space between the filler and the cuff is at least partially filled. The resulting narrowing of the annular gap reduces the risk that the laundry can penetrate into this room.

• this axial force component conveys the laundry forced into the front drum region back into the middle region of the drum and prevents laundry from entering the critical region of the gap between the sleeve and the filling body, without first making contact with the sleeve.
• the tendency of the laundry or portions thereof to be pushed forward out of the drum opening increases.
• the inventive shape of the packing results in the advantage that to the same extent, i. Also with increasing speed the tendency increases, by the drum-inward acting force, the laundry acts to bring back into the drum back.
• the surface resembling the shape of a sickle can be dimensioned and shaped discontinuously. Notwithstanding the preferred form with a constant pitch, the sickle surface may have a partially non-uniform slope along its extent.
• the Abweiser Ober of the packing can also be influenced by the fact that in the region of the indentation, the lateral surface area has a changing cone angle.
• the filler has two oppositely oriented imprints, whereby a deflecting effect is achieved in both directions of rotation of the drum.
• the oppositely directed recesses are designed symmetrical or asymmetrical.
• the symmetrical embodiment has the effect that equally large deflecting forces are transmitted to the laundry in both directions of rotation.
• in Main direction produces a stronger Abweiser Sign than in the opposite direction of rotation.
• the inventively designed washing machine reduces the friction of the laundry in the region of the filling opening and the risk that laundry out of the filling opening of the drum is conveyed out.
• the filler according to the invention causes a particularly gentle rejection of the laundry from the region of the filling opening. Friction damage to the laundry is significantly reduced and the service life of the cuff is increased.
• the additional expense associated with the invention is limited to the one-time production of a modified injection mold for the specially designed packing.
• the manufacturing process in the production of the filler as well as its installation in the frame of the loading door remain unchanged. Further adjustments or additional built-in parts are not required.

• the tub 2 and the drum 4 each have an opening 3 at the front, which are concentric with each other and lie almost in the same plane - therefore they both have the same reference number - and on which the drum 4 can be loaded and unloaded with the laundry.
• the opening corresponding to the feed opening 3 of the tub 2 / the drum 4 provided in the device housing opening is sealingly connected via a material-elastic rubber sleeve 5 with the opening 3 of the tub 2 and closed with a hinged door 6 hinged.
