       [0002]     The present invention relates to a front-loading drum-type washing machine including a drum rotatably mounted in a suds container, further including a bellows seal which is disposed between the suds container and the appliance housing for sealing the door opening area and which has formed thereon a laundry deflector in the region of the twelve o&#39;clock position, said laundry deflector being directed towards the drum, the washing machine further including a conduit for supplying water, wash or rinse liquid to the door opening area.  
       BACKGROUND  
       [0003]     In front-loading washing machines, it has become common practice to make the door opening relatively large, thereby making it easier for user to load and unload the drum. This requires, inter alia, a large opening in the front of the drum. Since the drum diameter is defined by the standardized housing widths, the width of the annular ring that acts as the front drum end wall is necessarily reduced because of the enlarged opening. As a consequence of this reduction in width, laundry is more likely to be pushed over the edge of the front drum end wall as the drum rotates, and then get jammed between the door glass and the bellows seal. Therefore, it is has been proposed, for example, in WO 02/12612 A1, to provide a laundry deflector in the region of the bellows seal and, more specifically, in the twelve o&#39;clock position. The laundry deflector is formed on the door sealing ring such that it is directed toward the drum and serves to return the laundry back into the rotating drum. For automatic washing machines having a large drum volume, it is necessary to reinforce the laundry deflector because of the high weight of the laundry. To this end, it is proposed in WO 02/12612 A1 that the clamping ring used to secure the bellows seal to the suds container be provided with a loop to be inserted into the laundry deflector. This may lead to difficulties during manufacture, because it is necessary to position the bellows seal on the suds container and the loop into the deflector at the same time, while also having to tighten the clamping ring in the process.  
         [0004]     In front-loading washing machines, it is also known to introduce water, wash or rinse liquid into the suds container or the drum in the area of the door opening. In the process, the liquid is either sprayed directly onto the laundry (DE 197 31 667 A1), or directed onto the door glass (DE 295 20 300 U1). In both cases, the wall of the bellows seal has an opening formed therein through which the liquid is passed into the interior of the drum via a nozzle or a hose line. A combination of direct injection and introduction by flushing via the door glass known from DE 197 31 667 A1. There, the tubular member, or the nozzle, directed toward the drum has formed therein an opening which is located in the immediate vicinity of the bellows seal and is directed toward the door glass.  
         [0005]     To provide for wetting of the laundry, it is necessary to use a nozzle that projects from the swinging fold. This results in the laundry rubbing against the nozzle, which causes wear of the laundry. German Patent Application DE 37 38 388 A1 describes a laundry appliance having a bellows seal which has an inflow channel formed in the inner wall thereof. This channel has an opening directed toward the drum, and thus provides for direct wetting of the laundry. This channel is located in the flat portion of the bellows seal and is deformable in nature, thus preventing damage to laundry items entering this region. In document WO 02/12612 A1, it is proposed to insert a nozzle as a separate part into a laundry deflector.  
         [0006]     German Patent Application DE 199 61 459 A1 describes a laundry appliance which has sensors disposed in the region of the door opening in the upper portion thereof. The laundry appliance described in DE 41 26 966 A1 has an illuminating device mounted in the bellows seal to illuminate the drum. These additional components are disposed in the portion of the bellows seal that is directed toward the housing opening, and thus in the movable portion thereof.  
       SUMMARY  
       [0007]     In view of the above, it is an object of the present invention to increase the stability of the laundry deflector in a front-loading drum-type washing machine of the type mentioned at the outset, and at the same time to simplify the design and manufacture of the washing machine, while also ensuring gentle treatment of the laundry.  
         [0008]     The present invention provides a front-loading drum-type washing machine. The washing machine includes an appliance housing; a suds container; a drum rotatably disposed in the suds container; and a bellows seal disposed between the suds container and the appliance housing and configured to seal a door opening area of the appliance housing. The bellows seal includes a laundry deflector disposed in a region of a twelve o&#39;clock position thereof. The laundry deflector is directed towards the drum and includes a channel system forming an opening in a wall of the bellows seal. A conduit is provided configured to supply at least one of water, wash liquid and rinse liquid to the door opening area, the conduit being in fluid connection with the opening in the wall of the bellows seal.

     DETAILED DESCRIPTION  
       [0013]     Advantages that can be achieved with the present invention are seen in the fact that by incorporating the channel system for liquid supply, there is no obstruction in the path of the laundry to be treated. This reduces the risk of damage occurring to the laundry. In addition, since the laundry deflector is positioned closer to the drum, and thus closer to the laundry, a more uniform wetting of the laundry is achieved. This completely eliminates the need for additional nozzles to ensure door glass flushing and laundry wetting at the classical positions. Another advantage results from that fact that the laundry deflector is stiffened by incorporation of the channel system. Finally, the combination of different functions into the laundry deflector allows for a reduction in the number of parts, thus simplifying assembly.  
         [0014]     According to the present invention, this is achieved in that the wetting of the laundry is performed by the laundry deflector while, in addition, door glass flushing can be performed together with the wetting of the laundry. To this end, the laundry deflector has a channel formed therein which, on the one hand, wets the laundry and, on the other hand, supplies water for flushing the door glass.  
         [0015]     For this purpose, it is convenient to manufacture the laundry deflector from elastic or partially elastic solid material, and to form the channel therein as a bore or through-hole. When the laundry deflector is integrally connected to the bellows seal, the laundry deflector is usually made of the same material as the bellows seal, and preferably of an elastomer.  
         [0016]     In a suitable embodiment, the laundry deflector originates at and extends radially from the hammer section toward the center of the door opening area. The laundry deflector has an extension formed on the outer end thereof, said extension pointing toward the interior of the drum and partially covering the gap between the hammer section and the edge of the drum opening. Thus, laundry items entering this region are reliably pressed against the laundry deflector and returned back into the drum by means of the laundry deflector.  
         [0017]     In an advantageous embodiment, the channel branches at a branch point, the branch channel for laundry wetting being directed toward the drum, and the branch channel for door glass flushing being directed forwardly toward the door glass. To control the amount of water required for door glass flushing, on the one hand, and for laundry wetting, on the other hand, the branch channel for laundry wetting has a larger cross-sectional area than the branch channel for door glass flushing. Thus, the water jet entering through the main channel is divided according to its intended functions.  
         [0018]     In an advantageous refinement of the present invention, the main channel extends in the region of the hammer section of the bellows seal, while the branch channels extend below the hammerhead region of the bellows seal. Furthermore, the upper portion of the main channel is enlarged to receive a connecting member for a water supply hose.  
         [0019]     It is advantageous if the connecting member, which is in the form of a tubular member, extends relatively far into the main channel. As a result, the tubular member acts as a reinforcement of the laundry deflector. For this purpose, it is convenient to manufacture the tubular member from a hard plastic. To further improve the fit of the connecting member, it is convenient for the inherently rugged connecting member to be secured to the suds container, i.e. to the front end wall in the area of the suds container opening, by means of a fastening element. For this purpose, it is possible to use, for example, a screw but other fasteners, such as insertion pins or clamps, could also be used.  
         [0020]     In an advantageous refinement of the present invention, a sensor and a light-emitting means can be incorporated in the laundry deflector, in addition to the water channel. Thus, in particular, the accesses points, which were usually distributed over the entire area of the swinging fold, are limited to one area, and more specifically to the region of the laundry deflector. This provides a bellows seal that ensures gentle treatment of the laundry.  
         [0021]      FIG. 3  shows a front-loading drum-type washing machine  22  having a housing  4  and a suds container  3  disposed in housing  4 . A drum  11  is rotatably mounted within suds container  3 . A bellows seal  1  extends in door opening area  2  between front appliance housing  4  and suds container  3 . In the operational position, door glass  24  extends at least partially into housing  4  in door area  2 . When washing machine  22  is in its normal position, a laundry deflector  5  is disposed or formed on the wall of bellows seal  1  in the upper region thereof, said laundry deflector extending toward drum  11 , i.e., toward the edge thereof.  
         [0022]      FIG. 1  is a sectional detail view showing a bellows seal  1  for a laundry appliance, especially a front loader. Bellows seal  1  is integrated into the laundry appliance in such a manner that it is disposed between the fragmentarily illustrated suds container  3  and machine housing  4  (also shown only fragmentarily) in order to seal door opening area  2 . In the front view of bellows seal  1  shown in  FIG. 2 , a laundry deflector  5  is disposed on bellows seal  1  in the twelve&#39;o clock position, said laundry deflector pointing toward the drum.  
         [0023]     As illustrated in  FIG. 1 , laundry deflector  5  originates at and extends from hammer section  6  toward the interior of the door opening area  2 . The laundry deflector has an extension  23  formed on the outer end thereof, said extension pointing substantially axially toward the interior of the drum. This extension  23  at least partially covers the gap between hammer section  6  and the edge of the opening of drum  11 .  
         [0024]     As shown in the cross-sectional view, wetting of the laundry is performed via laundry deflector  5  in the direction of arrow  6 , the liquid supply for laundry wetting  6  also providing for door glass flushing in the direction of arrow  7 . For this purpose, hammer section  15  and laundry deflector  5  are manufactured from an elastic or partially elastic solid material in which is formed a channel system  8  which supplies water for laundry wetting  6  on the one hand and for door glass flushing  7  on the other. Channel system  8  has a branch point  9 , one branch channel  10 , which is for laundry wetting  6 , being directed toward drum  11 . Another branch channel  12  is directed forwardly toward the fragmentarily illustrated door glass  24 .  
         [0025]     As shown in the cross-sectional view, branch channel  10 , which is for laundry wetting  6 , has a larger cross-sectional area than branch channel  12  for door glass flushing  7 . Branch channels  10  and  12  are approximately orthogonal to one another, main channel  8 . 1  being directed approximately toward door glass flushing  7 . Bellows seal  1  itself has a swinging fold  13  and, adjacent thereto, a hammer shaped section which, in turn, has contiguous therewith a shoulder  14  for engagement with the edge of suds container  3 . Laundry deflector  5  is integrally formed below the so-called hammer section  15 , main channel  8 . 1 . extending in the region of hammer section  15  of bellows seal  1 . Branch channels  10  and  12  are located below hammerhead region  16  of bellows seal  1 . The upper portion of main channel  8 . 1  is adapted to receive a connecting member  17 , so that a water supply hose  18  can be attached to connecting member  17 .  
         [0026]     As can be seen in the cross-sectional view, the upper portion of main channel  8 . 1  is enlarged, so that connecting member  17 , which is formed from hard plastic and takes the form of a tubular member  19 , can extend, or be inserted, relatively far into main channel  8 . 1 . This, in conjunction with water supply hose  18  and the deeply inserted tubular member  19  of connecting member  17 , creates a vibration damper, especially in the region of laundry deflector  5 . The damping action is advantageously assisted if connecting member  17  is additionally connected directly to suds container  3 , or secured to the edge of suds container  3  by means of a fastening element  22 , as shown in  FIG. 1 . In the present example, the attachment is by means of a screw inserted into the material of suds container  3 . Other fastening elements, such as insertable pins or clamps, could also be used. Using this fastener  22 , laundry deflector  5  is particularly well stabilized relative to suds container  3 .  
         [0027]     The elevation view A of  FIG. 2  illustrates the situation on the outlet side toward drum  11  ( FIG. 1 ), showing, on the one hand, the opening region of branch channel  10  in the middle of laundry deflector  5 , and, to the left thereof, an opening region  20  which may be intended for a light-emitting means, and, to the right of thereof, a further opening region  21  which may be intended for a sensor. Sensor  21  is preferably an optical sensor and serves to detect any laundry (not shown) that may have been pulled into the gap between bellows seal  1  and drum edge  11  ( FIG. 1 ) in this area. When such a condition is detected, suitable steps may be initiated, such as aborting the spin cycle and/or redistributing the laundry. Furthermore, the sensor may be used to detect high foam volume or to sense the condition of the wash liquid (turbidity, conductivity, pH, etc.).  
         [0028]     The present invention is not limited to the embodiments described herein; reference should be had to the appended claims.
