WASHING MACHINE DRUM

The technical area of the invention concerns drums of wash automats, which exhibit openings in cylinder-like form, which turn with the help of an electrical engine around the longitudinal axle of the drum on the surface.

The washing machine drums consist generally of a cylinder-like corpus, which is installed to the caustic solution container with its axle in horizontal position, a cylinder-like corpus, which exhibits a closed rear wall element of the same and an open wall element as front charging hole for the additional load of the clothing in its internal area.

There are also drums with größ erer amount of filling, whereby in this case both wall elements are closed, if in the side panel a for this purpose appropriate opening is present.

In any case the drums of the washing machines are provided with numerous openings, which are so appropriate on their lateral and round surface, daß the number of openings a remarkable broad diameter exhibits, in order to attain an optimal wash result. Auß the number of openings is limited for erdem to increase in order not to harm the side panel of the drum, since at present the tendency exists, the speeds of the centrifuge procedure and for the case, daß the drum as consequence of a increased number of openings and one groß EN of diameter the same would be impaired, can it to a Reiß EN and even for the damage of the clothes with their friction on the edges of the mentioned openings come, because their punched cutout normally exhibits lack and therefore edges, which attack both by friction as well as by getting stuck the clothes.

Regardless of its drums are well-known with washing machines with a decreased number of openings and a small diameter, whereby de Oberfläche of the drum wall works less attacking. Auß to erdem the decrease of the diameter of the openings does not permit depressing sections of the clothing, which against it with groß EN diameters the case is.

The available invention concerns, as in the title is expressed to this describing description, the drum of a washing machine, the characteristic exhibits a presenting element on the contact range of the clothes to have, so that the aggressiveness, the articles of clothing are exposed to which normally by the appropriate edges of the openings and are provided with those the side of the drums of the washing machines, is avoided.

Task of the invention is to be avoided, daß the articles of clothing, which are entered into the drum of a washing machine, during their washing process are impaired as well as to prevent, daß the drum when washing aggressive articles, as, damage suffers shoes.

Those erfindungsgemäß e drum of the washing machine exhibits the characteristic, daß the drum trained in form of a cylinder-like corpus with a rear wall and a Vorderwand, whose mentioned cylinder-like corpus on its side exhibits openings for passing the water contained in the caustic solution container for the internal area of the drum, had at least a presenting element, which is arranged on the side of the drum, where their openings are present, and on a range or on none the rear wall and a range or none the Vorderwand, the aggressive effects on the articles of clothing and on the wash drum it minimizes. Auß erdem the admission of the presenting element varies the vibration way and - frequency of the drum, whereby the noises of the washing machine are reduced.

It is insignificantly, whether the washing machine a front loader is appropriate for higher additional loads or, there the presenting element for all kinds of washing machine angepaß t will can.

With an execution variant the presenting element can be arranged in the internal area of the drum and exist of a foil made of plastic material with holes of small diameter, which are very numerous, around the Durchfließ EN of the water into the drum inside to favour, however exhibit a very small diameter, so that the articles of clothing when hurling with high speeds by passing through these suffers no damage. In this way the drum from rustproof steel does not need mirror-similar processing, which is no longer visible more attractively, but for the customer. That whenever the presenting element or interior foil is not removable.

The mentioned foil can be likewise flat, exhibit a graining or different geometrical forms. The geometrical forms are very important, since on a flat rotation drum a presenting foil can be entered, which consists of plastic and only one piece, which integrates Wasserbrechelemente, which usually exhibit the drums in the usual washing machine remarks made of metal.

The geometrical forms of smaller Größ e with curvatures serve a more careful treatment of the clothes, because they avoid the articles of clothing still more from the metal drum beabstanden and, daß it at them get stuck. They reduce likewise in considerable way the noise of the washing process, since it comes to no friction between metal parts, which can exhibit the articles of clothing, but above all if articles größ eren weight to be washed, which are cushioned with stronger Kraft against the drum to strike and.

A further effect of the curvatures or the raised training consists of it, daß it as memory of water serve, which they release during the washing process as well as a showering effect on the articles of clothing, in the moment, in which the drum terminated the rotation, to exactly cause.

These raised training can be present, as preceding already mentions, even in more pronounced forms, in the kind of Wasserbrechelementen, whereby the production of these indispensable elements on metal drums is avoided, whereby it comes with the production to a saving. Since it is manufactured in a foil from one or more pieces, all raised kinds of training can be used, which favour the movement of the Kleidungstücke in the drum as well as the washing process.

This foil can be in principle made of plastic or also metal, in the kind of a thin foil or also a mesh or a metal net with a rather closed mesh network, whereby it one still größ eren impression at cleanliness lends.

This foil can fix itself during the washing process due to the own centrifugal energy, if however necessary, it cannot with removable or removable tie-clips at the openings of the drum or by means of screws or rivets, if a stationary form is preferred, is attached.

The removable version represents an advantage, since it can be used in washing processes, where it is actually necessary, for example when washing heavy articles such as footwear, or if groß e centrifuge speeds are necessary. And there is then also the possibility of arranging the presenting element in already available drums there the Größ EN of the drums usually standard versions correspond. And in the case, daß the foil would be damaged, would be easily exchangeable it.

With another variant of the execution the presenting element can insist that of a plastic volume, on the Auß enfläche fastened is prevented, whereby a part of the plastic passes through the openings of the drum and in their internal area in wart form in-been enough, over a cover and a protection of the edges of the mentioned openings to specify and, daß the clothes are damaged.

The volume mentioned knows the Auß enfläche of the drum totally or partly cover and can to these by suitable means be fastened, such like tie-clip, screws, etc., although to its attachment also the adjustment is sufficient, which the warts of the plastic volume, which pass through in the openings, experience.

And to the differentiation or lending a more attractive character, for example, daß the clothes in the drum in the eye jump, exhibit the presenting element another or the same color of the material of the drum, whereby it lends a new and attractive aesthetics to the washing machine drum.

For the case, daß it from plastic material exists, can the foil mentioned by means of injection or another procedure be manufactured, that the production of foils of different Größ EN, forms, colors, etc., permitted, whereby it must be provided in each case with openings, in order to permit the flow of the washing water.

For the case, daß the foil metal-like is, can it out very fine wires, in the purpose helpful a form and a Größ EN manufactured its.

And schließ lich, by at the disposal to a drum, which is to be used more versatile, becomes an enormous improvement in the efficiency of the wash puts - and centrifuge procedure reaches.

With all these characteristics presenting elements can be used into geometrical and functional variations, depending upon model and achievement.

To the completion of the following description and over to a better understanding regarding the characteristics of the invention to help, the available describing description a drawing set is added, by which the novelties and advantages of the washing machine drum with the improvements of the invention are better understood.

• Figure 1. - Shows a perspective scrap view of a drum with the presenting element, which is arranged in their inside, whereby the mentioned presenting element consists of a foil with openings of small diameter and raised training in the form of curvatures.
• Figure 2. - Shows an opinion in the partial section of a drum gemäß a cutting plane, which lies perpendicularly to the rotation axle of the drum, with which arrangement of the presenting element in the internal area, whereby the mentioned presenting element of a foil with openings of small diameter and raised training consist in the form of curvatures, in which the washing water collects, which enters by the openings of the drum and enters the moment, in which it stops the rotation, it the kind of rains by the small holes of the foil.
• Figure 3. - Shows a perspective opinion of a presenting element in form of a foil, which consists of plastic, in order to the internal area of the drum to be introduced.
• Figure 4. - Shows the perspective of a drum with the presenting element in volume form, that auß EN on the side of the drum is arranged.
• Figure 5. - Shows a cutaway view gemäß the cut line A-B of the figure 1, where the presenting element with the warts, which are arranged in the openings of the side of the drum, is to be seen.

With regarding the mentioned figures a drum 1 in cylinder-like training is to be seen, those by a wall, which corresponds to its rear wall, is closed, in its arrangement on the caustic solution container of a washing machine and with its front opening 2 for additional load.

In the figure 3 a presenting element in form of a foil 3 made of plastic is to be seen, by a Einspritzteil of different raised training 2 in the form of curvatures, how you can recognize raised training in the figure 1 as well as in the form of Wasserbrechelementen 8 are formed, which is so arranged, daß it sufficient consistency exhibits, in order to remain clinging in the internal area of the drum 1 with sufficient flexibility, in order to introduce it by the front wall 2, which is the opening to the Zuladen of the clothes which can be washed into a washing machine with front loader.

The curvatures 7 call a showering effect, as in the figure 2 is represented, out, if the drum 1 in the current wash program stops the rotation and the water between them and the drum 1 for a short instant is stopped.

The volume 3 consists of plastic material and has some tie-clips, which engage into the openings 4 of the drum 1, so that it not while to the rotation of the washing process by the articles of clothing is along-pulled. The foil 3 is provided with small holes of smaller diameter, than those the drum 1, whereby it groß e density per unit area exhibit.

The side of the drum 1, where the openings 4 meet are without interruption, without daß they mechanically to be worked on are or the Wasserbrechelemente added must, since these are integrated in the foil 3.

The presenting element can consist on the other hand of a thin metal plate, whereby those holes in größ erer or smaller number and with größ erem or smaller diameter to exhibit can, in order to permit the flow of the washing water. It can consist also of a metal net with fine twisted wire and expressed closed network.

In figure one can see 4, like the mentioned drum 1 with a volume 6 from plastic material is equipped, this in coating form on the lateral Auß enfläche adheres, the volume to 6, which is so trained from plastic material, daß some of it by the openings 4 of the drum 1 passes through and in its internal area projects, by disguising the edges of the same openings 4 and forms warts 5, as is to be seen 5 in the detail of the cut of the figure.

If the presenting element auß EN is arranged and from a volume 6 exists, can this the side of the drum 1 totally or partly coat and by that bloß e adhering the warts 5 with their attachment on the openings 4 to this to stick remain or it can be fixed by screws, clips, tie-clip etc.

If the presenting element is arranged on the other hand inside and consists of a foil 3, it can by itself, by which centrifugal Kraft, which is produced during the revolution of the drum 1, are fixed.
