Description

Drum of a careful treat machine of the clothes.

Field of the art of the invention

The present invention relates to a drum of a careful clothing treating machine, in particular of a washing machine, a washer dryer, a dryer, or similar, according to the general concept of claim 1. The invention further affects a careful treating machine of the clothes with such a drum.

Background of the invention

From EP 1 568 812 A2 and EP 1 505 188 A2, it is known respectively, as in Fig. 12 depicted, a corresponding drum 200 of a washing machine according to the concept general of claim 1, with a drum housing 400 in its basic shape in cylindrical principle, with a cylindrical shaft, the which constitutes the axis of rotation A, around which the housing of 400 drum is rotatable. The drum housing 400 has a section main housing 400a in the form of a tube, with a first and second front wall 400b, 400c, which are joined with a first and second axial edge zone of the main section of 400a housing The drum 200 also has at least one element of reinforcement, which surrounds the main housing section 400a in the outer perimeter of the drum and acts against a bulging of the main section of housing 400a under the influence of force centrifuge (indicated in Fig. 12 by means of a thick line interrupted) during drum rotation 200. Thanks to this ensures a reliable connection of the first and second front wall 400b, 400c with the first and second axial edge zone of the main section of housing 400a, which could otherwise be damaged during a rapid rotation of drum 200 and a strong bulge of the main housing section 400a. The element reinforcement is respectively in both of the documents mentioned in the prior art, a 500 or reinforcement belt metal reinforcement belt, that is a metal tape of a thin metal sheet.

While the 500 reinforcement belt represents basically a high quality solution, manufacturing and application of the 500 reinforcement belt to the drum is however, in which respects manufacturing techniques and assembly techniques quite complicated and expensive, and requires tools and machines special. The cross section of the reinforcement belt 500 must be almost always carried slightly to the arch form, so that the convex side of the belt can then be placed in such a way that the edges of the strip 500 do not rub the drum afterwards. He applied from the 500 reinforcement belt to the prestressed low drum demands also a high aparative effort, as well as special precautions or tensioning elements in the same reinforcement belt 500. Such type 500 reinforcement belts are for that reason not adaptable or only adaptable with extreme high stresses to different sizes and shapes of drums, for example of different washing machines or machines for careful treatment of clothing.

Description of the invention

The invention is therefore based on the task, respectively the technical problem of creating a drum with a reinforcing element of the type named at the beginning, which is manufactured in a simple way and in an effective way and is applicable to the main housing section, and still acts reliably against a bulge of the main housing section during a fast rotation of the drum, and which can also be used For different sizes and drum shapes. In addition, it must be put available a careful machine for treating clothes with such type of drum

This task will be solved according to a first aspect by means of a drum in accordance with the invention, with the characteristics of claim 1.

This drum of a careful treat machine of clothes, in particular of a washing machine, of a washer-dryer, dryer, or similar, is provided with: an essentially cylindrical drum housing in its basic form, with a central cylindrical axis, which forms an axis of rotation around which the drum is rotatable, where the housing drum has a main section of tube-shaped housing with a first and a second front wall, which are joined with a first and a second axial edge zone of the main housing section; and at least one reinforcing element, the which surrounds the main housing section on the outer perimeter of the drum and acts against a bulge of the main section of housing during a drum rotation under the influence of the centrifugal force, characterized in that the reinforcing element is at least one string-shaped element, which surrounds at least one the outer perimeter of the main housing section. He drum is characterized in that the reinforcing element is at least one string-shaped element, which wraps at least one the perimeter of the main housing section.

Under a rope-shaped element in the sense of the invention, it is understood that each type of element is made with at least one wire or at least one fiber or at least a similar elongated ductile filament or element (and therefore also flexible) for the transmission of tensile forces. He rope-shaped element is made from a plurality of loose wires, cords, fibers or filaments, which for example they are twisted, braided or in (one) other way and optional way, grouped into one or more fascicles The rope-shaped element also has a some elasticity The shape of the cross section or the shape of the cross section profile of the rope-shaped element is, in essence preferably circular, elliptical, or at least rounded.

Since in the case of the drum in accordance with the invention, the reinforcing element is an element in the form of string, can this be attached to the drum or its section main casing in a simple way and way, in what It respects manufacturing techniques and assembly techniques. He rope-shaped element can for example be unwound during the manufacture simply of a coil, cut to length needed and wrapped to the drum and fixed to it. For this they are not necessary tools or special machines. As an element in string elements are also allowed to use standard elements, such as standard stainless steel wire ropes, or similar. These already have a conventional cross section circular or rounded, which ensures that the element in rope form in final state of assembled and in operation of drum, do not rub on its outer side. In contrast to the described above state of the art, it is not necessary in this case no treatment or deformation of the reinforcing element.

The rope-shaped element is wrapped also under prestressing, around the outer perimeter of the main section of housing and fixed in this state, fit relatively simple and without expensive operating means. Due to the ductility of the rope-shaped element, can it also be easily wrapped in several turns and with a step angle (or also with different local passage angles) around the main housing section, and in this sense he can reach in case of need different sites of the outer perimeter of the main housing section. This allows to reinforce the drums, in places under special effort, in a manner and manner simple and effective. The rope-shaped element is usable also for the reinforcement of drums of different size and / or drums of different types of machines carefully treated the clothing, without an essential adaptation or modification of the rope-shaped element and its tools mounting. The manufacture of the drum in accordance with the invention It is for this reason, compared to drums already known, more Simple, more effective and cheaper. Beyond that, the element acts by safely and reliably counteracting a unwanted bulging of the main housing section, during fast drum rotation (for example 1400 turns per minute or more).

Other preferred and advantageous features of embodiment of the drum in accordance with the invention, are subject of claims 2 to 26, which find support below in the description of the examples of preferred embodiment.

The task that underlies the invention is solved in more by a careful treat machine of the clothing according to the invention, with the characteristics of the claim 27.

The machine of careful treatment of clothes, in particular a washer, a washer dryer, a dryer, or similar, has a drum according to one or more of the claims 1 to 26.

With the careful clothing treating machine In principle, the same technical advantages that have been achieved are achieved set out above, in context with the drum in compliance with the invention

Preferred embodiments of the invention with aggregate design details and other advantages are described and clarified below in depth, under reference to attached drawings.

Description of a preferred embodiment

In the following description and in the drawings, to avoid repetitions, as long as none is necessary other differentiation, will also be designated with the same symbol components and equal parts.

A view is shown in Fig. 1 longitudinal schematic out of scale, through a drum 2 in accordance with the invention (here: a drum of a washing machine), according to a first embodiment. This drum 2 has a drum housing 4, in its essentially cylindrical basic form, with a central cylindrical axis, which forms an axis of rotation A, around which drum 2 is rotatable. Drum housing 4 it presents a main section of tube-shaped housing 4a, with a first and a second front wall 4b, 4c, which are joined with a first and a second axial edge zone RB_ {1}, RB_ {2} (in the drawing, indicated respectively with a circle with dashed line and dot). The union takes place in this example by a folded joint 6. A joint is also possible welded, an integral formed of the cited parts, or any other  appropriate optional union.

The drum 2 also has at least one element of reinforcement, which surrounds the main housing section 4a in the outer perimeter of drum 2, and acts against an arc of the main housing section 4a during drum rotation 2 under the influence of centrifugal force (in Fig. 1 indicated through an interrupted thick line).

This ensures good durability of the folded joint 6 and thereby a safe and reliable connection of the first and a second front wall 4b, 4c, with the first and a second axial edge zone RB 1, R 2 of the section main housing 4a, which could otherwise be damaged, in the case of a rapid rotation of the drum 2 and a strong arching of the main housing section. 4th. As indicated in the drawing, the reinforcing element is at least one element in the form of string 8 (briefly referred to below string 8), the which wraps at least once the outer perimeter of the section main housing 4a. In the present embodiment it is provided A simple wrap. In the final state of assembling the rope 8, this wraps the main housing section 4a preferably under pretense.

As can be seen in Fig. 1, the rope 8, with respect to the axial extension of the main housing section 4th, it is ordered in a middle area of it.

As rope 8, in this embodiment a standard steel rope, stainless steel, resistant to corrosion. The rope 8 has a diameter of approximately 2.5 mm and essentially a round cross section. Depending on the size of the drum 2 and the expected rotation speed, you can find with Every application, of course, also other diameters. Rope 8 it is preferably made of a plurality of elements separate twisted, fasciculated or otherwise grouped. In a very simple realization can however be also a unique wire or similar

For rope 8 they are basically usable also other appropriate materials, that is, other material stainless or anticorrosive. Thus, the rope 8 can be produced for example also of a plurality of non-metallic fibers, with a plurality of filaments or a material of a compound of fibers

More details can be obtained from Figs. 2 and 3 of drum 2 in accordance with the invention. Fig. 2 shows in this case a schematic perspective exterior view of a first site of drum 2 in accordance with the invention of (the) Fig. 1, with a view in the direction of its longitudinal direction, or axial direction (compare reference symbol A).

       \ global \ parskip0.900000 \ baselineskip
    

And Fig. 3 shows an exterior view schematic perspective of a second drum 2 site in in accordance with the invention of Fig. 1, also seen in direction to its longitudinal direction, or axial direction.

As sketched in Fig. 3, the section main tube-shaped housing 4a, is manufactured from a basic plate-shaped material (here: steel plate stainless), which is deformed into a tube-shaped structure and on two edges of the plate that correspond to each other, embedded over an area of lace B_ {F} extended along in principle parallel to the cylindrical axis A. The fitting area B_ {F} extends especially the width of the main housing section 4a. At present example both edges of the plate are joined by means of a folded joint V_ {F}. For reinforcement of the folded joint V_ {F} is the same, beyond the lace zone B_ {F}, provided with several ribs 10, whose respective axes longitudinal 10_ {A} extend essentially in (the) perimeter direction of the main housing section 4a. In more, the main housing section 4a presents on its surface outer perimeter several bends in the form of groove 12, which extend essentially parallel to the axis of rotation A, which form respectively on the inside of the main section of housing 4a a type of shovel-shaped breaker. The area of transition of the bends in the form of groove 12 with the surface outer perimeter of the main housing section 4a is rounded.

The rope 8 in this example is shaped as a finite string, whose ends 8a, 8b in the assembled state (it is that is, in a state of attachment to the main housing section 4a) are linked together by means of a rope binding element 14. The rope 8 may in principle be shaped however also as an endless rope, for example in the form of a rope cancel. The rope binding element 14 is preferably a rope binding element, which is chosen from a group of rope binding elements, comprising: a union by shape, a friction driven joint, an adhesion joint or glued, in particular one joint per knot, one per braid, one per interlaced, one spliced, a welded joint (strong), a solder joint (soft or brass), a cast iron joint, a union by clamps or by pressure, (for example also by two bolted elements or partial elements rivets), a joint by interlocking, a union by hitch, a combination of at least two of the previously named elements of rope union As rope connection element 14 it is used in this example a connecting element by clamps or by pressure, as described in more detail below.

As can be recognized in Fig. 2, the rope binding element 14 is ordered to the first site of the drum 2, in accordance with the invention, in the area of one of the slot-shaped bends 12. Depending on the quantity of the slot-shaped bends 12 distributed around the perimeter of the drum 2, is this first site (see Fig. 2), referred to in principle circular cross section of drum 2, section of the second side (see Fig. 3). In three corners the first side is facing straight approximately 120 ° to the second site, in two, four, eight etc. 12 corners preferably facing 180 °. He rope binding element 14 is arranged, at least in part (here: with its lower side), inside corner 12. Since the second site (see Fig. 3) that site is, which presents the zone of elongated lace B_ {F}, the rope binding element 14 in this example of embodiment is thus ordered to an area of the perimeter of main housing section 4a apart (preferably exactly opposite) of the lace zone B_ {F} elongated. In the area of the second site runs the rope 8 preferably through one of the grooved bends 10, of such that it secures the rope 8, in the axial direction (compare with A) of drum 2, against lateral sliding.

In Fig. 4, which shows a view Longitudinal schematic through the rope 8, are illustrated further technical details of the rope 8 and its connecting element of rope 14. The rope connection element 14 has at least one first connection element 14a, which is fixed or is attachable to the first end of rope 8a, and at least one second connection element 14b, which is fixed or can be fixed to the second end of rope 8b. Each connection element 14a, 14b it has a rope junction zone 14a1, 14b1, in which it is fitted the respective end 8a, 8b of the rope 8. The respective rope junction zone 14a1, 14b1 is pressed with the end 8a or 8b respective belonging. Both connection elements 14a and 14b are formed insertable to each other. The element of connection 14b is in this case structured in capsule form and it has a reception area in the form of a tube 14b3 with a zone of deformation 14b3. The connecting element 14a is formed as a kind of bolt. The connection element 14a has a head 14a2 with an outside diameter, which is insignificantly more smaller than the inside diameter of the reception area 14b3 of the corresponding connecting element 14b in capsule form, of such  so that both connection elements 14a, 14b are allowed to be inserted Easily in each other. Head 14a2 splices a cylindrical section extended along, passing through a step or shoulder, which has a smaller diameter than it has the head 14a2 and forms the rope junction zone 14a1. Fit alternative this zone 14a1 can present in its outer perimeter for example also several protrusions in the form of rings or others appropriate elements for a union logical-conclusive. The connection element 14b it has a limiter 16 for the head 14a2 of the connecting element 14 to.

To facilitate assembly to the main section of housing 4a, the rope 8 is in this example already pre-assembled as a mounting unit, with the rope binding element 14 or well its loose components, which has a mounting length L_ {M} default. For mounting length L_ {M} it is valid in this example:

L_ {M} = L_ {A} - D_ {X}

In this case, L_ {A} is the length of the outer perimeter of the main housing section 4a, in the zone in which the rope 8 must be located, and D_ {X} is a relevant measurement length for subsequent elastic tensioning reversible of the rope 8. In this example, it is the actual length of rope L_ {S}, to which it must be cut for the manufacture of the above-mentioned assembly unit the rope 8, somewhat smaller than that of the mounting length L_ {M}, since the connection elements 14a and 14b themselves have a certain length.

Fig. 5a shows a schematic view longitudinally through the rope 8 or the mounting unit of Fig. 4 in a first unmounted state, in which the rope 8 Loosely wrap the main housing section 4a (no represented). Fig. 5b shows a schematic view longitudinally through the rope 8 of Fig. 4 in a second state, in which it is mounted, and its rope ends 8a, 8b a through the rope binding element 14 are firmly attached each other, and in which the rope 8 envelops the main section 4a housing under pretension.

When the rope 8 is in the first status (Fig. 5a) and connection elements 14a and 14b are inserted together, the head 14a2 of the connecting element 14a is positioned at a predetermined distance D_ {X} in front of the limiter 16. In this way, the rope 8 or the named mounting unit, a first wrap length default, which corresponds here to the mounting length L_ {M} and which, as already said, is somewhat shorter than the length of the outer perimeter L_ {A} of the main housing section 4th. To be able to carry the rope 8 or the assembly unit now to the above mentioned second state, the rope 8 is tensioned until head 14a2 reaches limiter 16 (Fig. 5b). The area of reception 14b3 serves in this case in parallel as an element of guided for head 14a2. Tensioning can take place with a relatively simple tool, which is attached to both connection elements 14a, 14b. In the second state (Fig. 5b) the 8 string or the reversible and elastic mounting unit, is then extended to a second predetermined length of wrap, which is somewhat larger than the first default wrap length and corresponding in principle with the length of the outer perimeter L_ {A} of the main section of 4a housing. In this way, the rope 8 in the assembled state, Wraps the main housing section 4a under pretense. Is Obviously they define, with predefined string parameters, drum parameters and a preset mounting length L_ {M}, the rope binding element 14 or the actuation joint of its connection elements 14a, 14b and the limiter 16, the length of the second round and the magnitude of the prestressing of the rope 8. The rope binding element 14 exercises in this example at the same time, the function of a string tension element and security element.

In order to reach the prestressing of the rope 8 mentioned above, it is basically also possible to use a rope 8 or a mounting unit, which / which it has in the second been a length which is less than the perimeter length exterior L_ {A} of the main housing section 4a. This it would mean, however, that the drum 2 by means of the string 8 It is then locally strongly pressed into itself. This possibility should be widely avoided, since the sheet metal Drum 2 is usually very thin.

A compound form is also possible from of the first and second variant, and represents in practice a real solution, since not only rope 8 but also the drum 2 always show a certain elasticity or compromise. In the second state (Fig. 5b) the deformation zone 14b2 of the right connecting element 14b is plastically deformed and pressed to the outer perimeter of the rope junction zone 14a1, such that the material of the deformation zone 14b2 surrounds head 14a2 both in (the) radial direction and in the axial. The rope connection element 14 therefore configures a type of pressure terminal, where both connection elements  14a, 14b, in pressed state, referred to the address longitudinal of the rope 8, have a shape logical-conclusive. The rope union is by such reason reliably secured and cannot be released even during high drum rotation speeds 2.

Fig. 6 shows a schematic view longitudinally through a rope binding element 18 of the rope 8. This rope binding element 18 resembles the element  of rope connection 14 of Fig. 4, 5a and 5b. As opposed to this, however, has two connection elements 18a, 18b, which are structured respectively as the element of connection 14a of the variant of Figs. 4, 5a and 5b. It also has the construction according to Fig. 6 a separate intermediate capsule 18c, with a left and right lace opening, in which they are inserts the first and second connection elements 18a, 18b, which are attached respectively with a rope end 8a, 8b. The intermediate capsule 18c has an inner wall of separation 18c1, whose lateral surfaces serve respectively as limiter 16 for a head 18a2, 18b2 of the respective elements connection 18a, 18b. The intermediate capsule 18c works by consequently as a limiting element separate from the element of rope junction 18, to which at least one first is assigned and a second connection element 18a, 18b is assigned to it. The securing connection elements 18a, 18b to the capsule intermediate 18c, and with it the union of the ends of the rope, as well as the tensioning of the rope 8 takes place in analog form with the variant according to Fig. 4, 5a and 5b. That is to say that the heads 18a2 and 18b2 are close, and the areas of capsules 18c2 are pressed on the rope junction zones 18a1, 18b1 of the connection elements 18a, 18b and surround the respective head 18a2, 18b2 in radial and axial direction. The intermediate capsule 18c it also serves as a tension and secured element for the rope and connection elements 18a, 18b.

For the aforementioned mounting length L_ {M} is valid in this variant:

L_ {M} = L_ {A} - (D_ {X1} + D_ {X2})

D_ {X1} and D_ {X2} can be the same or unequal The sum of D_ {X1} + D_ {X2} must correspond as possible with the value D X of the example according to Fig. 4, 5a and 5b, in order to achieve tensioning relationships in the rope 8, when this one is in the above mentioned second state.

Fig. 7 shows a schematic side view out of scale of a drum 2, in accordance with the invention, of according to a second embodiment. In this variant it involves the string 8 several times the outer perimeter of the main section of housing 4a, that is in several turns W1 to Wx. Laps neighbors run in this example extended, directly next to each other of the other, that is to say in principle without intermediate spaces. Of the the same way is possible, however, to provide an intermediate space between turns W1 to neighboring Wx. Rounds W1 to Wx of the 8 string may be wrapped, with equal pitch angles and / or different, around the main housing section 4a.
